  • Common Frequently Used Financial Terminology: Explanations & Practical Applications

    Preface

    Financial terms widely appear in scenarios including personal wealth management, stock and fund investment, cross-border trade, bank lending, and financial news. Although many professional terms seem obscure, they are closely linked to ordinary people’s income, savings, asset planning and corporate operation. This article categorizes the most globally universal financial terms by usage scenarios, paired with plain-language explanations and real-life or commercial application cases, helping overseas readers, small and micro business practitioners and new investors quickly grasp relevant knowledge. Written from a neutral popular science perspective, this guide mainly focuses on the functions and practical uses of financial instruments.

    Table of Contents (Six Sections Covering Scenarios from Personal Finance to Cross-border Business)

    Section 1: Basic Personal Finance (Most Commonly Used in Daily Life)

    Liquidity

    Plain explanation: The ability to convert assets into cash rapidly without suffering substantial losses.
    Application scenarios: Current deposits feature high liquidity and can be withdrawn at any time; real estate and large-denomination time deposits have low liquidity and require a long period to be converted into cash.

    Annualized Rate of Return

    Plain explanation: Converting returns generated over a certain investment period into an annual percentage to compare the profitability of different financial products horizontally.
    Application scenarios: If a 3-month financial product yields a 2% return, its annualized rate of return can be calculated for comparison with the interest rate of one-year time deposits.

    Compound Interest

    Plain explanation: Also known as interest upon interest. Interest generated by the principal keeps earning new interest in the next interest calculation cycle.
    Application scenarios: Long-term regular fund investment and bank compound-interest deposits deliver increasingly remarkable asset appreciation benefits as the investment period extends.

    Equal Principal and Interest / Equal Principal Repayment

    Plain explanation: Two mainstream repayment methods for mortgage loans. The monthly repayment amount remains fixed under the equal principal and interest method; the equal principal method requires fixed monthly principal repayment with gradually decreasing interest, leading to higher repayment pressure in the early stage.
    Application scenarios: These two repayment modes are widely adopted for housing loans, consumer installment plans and business loans.

    Personal Credit Report

    Plain explanation: A credit record compiled by financial institutions to document individuals’ borrowing, repayment and credit card performance, serving as the core reference for banks to approve loan applications.
    Application scenarios: Excessive overdue credit records may result in rejected applications for housing loans or car loans.

    Section 2: Investment & Wealth Management (High-frequency Terms for Funds, Stocks, Bonds and Asset Allocation)

    Asset Allocation (Diversified Investment)

    Plain explanation: Avoid putting all capital into a single product. Split funds across various asset types such as deposits, funds, bonds and gold to reduce overall investment loss risks.
    Application scenarios: An individual allocates 60% of capital to stable bond funds, 30% to index funds and keeps 10% in current cash to hedge against losses caused by declines in a single market.

    Public Funds & Private Equity Funds

    Plain explanation: Public funds raise capital openly from all individual investors with low investment thresholds and strict regulatory oversight; private equity funds are only offered to high-net-worth individuals and professional institutions with more flexible investment strategies.
    Application scenarios: Stock funds and bond funds purchased by ordinary investors via wealth management platforms all belong to public funds.

    Index Funds

    Plain explanation: Passively managed funds that track the performance of broad market or industry indices. Instead of relying on fund managers’ subjective stock selection, they mirror overall market trends with lower management fees.
    Application scenarios: CSI 300 and S&P 500 index funds are popular long-term regular investment products among global investors.

    Price-to-Earnings Ratio (P/E Ratio)

    Plain explanation: A core indicator to measure the valuation level of a stock, indicating how many years it will take to recoup the investment based on the company’s current earnings. A higher P/E ratio generally means the asset is overvalued.
    Application scenarios: Comparing the P/E ratios of two listed companies in the same industry helps judge which stock offers better investment value.

    Price-to-Book Ratio (P/B Ratio)

    Plain explanation: The ratio of a company’s share price to its net asset value per share, often used to evaluate the valuation of enterprises in capital-intensive industries.

    Treasury Bonds & Corporate Bonds

    Plain explanation: Treasury bonds are issued with sovereign credit guarantee and carry extremely low risk; corporate bonds are issued by listed companies and large enterprises, offering slightly higher yields than treasury bonds with a small risk of default.

    Profit Taking & Stop-Loss

    Plain explanation: Setting pre-determined profit targets and loss limits in advance to sell assets automatically once price thresholds are reached, avoiding holding positions out of greed or suffering massive investment losses.

    Section 3: Capital Market Terminology (General Terms for Stock Markets and Corporate IPOs)

    IPO (Initial Public Offering)

    Plain explanation: The first time a private company issues shares to the public, lists on a stock exchange, and raises capital for corporate expansion by selling equities.
    Application scenarios: New energy and biopharmaceutical companies complete IPOs to secure funds for production line expansion and R&D investment.

    Total Market Capitalization

    Plain explanation: Calculated by multiplying a listed company’s total share volume by its current share price, reflecting the overall valuation of the enterprise in the capital market.

    Turnover Rate

    Plain explanation: The frequency of stock trading within a certain period. A higher turnover rate indicates more active trading of the stock.

    Restricted Shares

    Plain explanation: Shares held by company founders and strategic investors that are subject to a lock-up period. They can only be freely traded on the secondary market once the lock-up term expires to prevent sharp stock price drops caused by large-scale concentrated sell-offs.

    Going Long & Going Short

    Plain explanation: Going long means buying assets at a low price and selling at a high price to earn spreads when price growth is expected; going short involves borrowing assets to sell first and repurchasing them at a lower price later to make profits from anticipated price declines.

    Section 4: Corporate & Cross-border Trade Finance (Common Terms for Foreign Trade and Small Businesses)

    LPR (Loan Prime Rate)

    Plain explanation: A market-based benchmark interest rate adopted by commercial banks for corporate and personal loans, dynamically adjusted according to market capital supply and demand.
    Application scenarios: Interest rates for personal housing loans and small business operating loans are mostly set based on LPR plus a fixed spread.

    Working Capital Loan

    Plain explanation: Short-term bank loans granted to enterprises to cover raw material procurement, staff salaries and daily operational turnover costs.

    Banker’s Acceptance Bill

    Plain explanation: A payment instrument guaranteed by a bank for unconditional payment upon maturity. Enterprises can use it instead of cash in trade settlements to ease short-term cash flow pressure.

    Letter of Credit (L/C)

    Plain explanation: The most widely used settlement tool in international trade. Acting as a third-party guarantor, a bank must release payment to exporters once compliant shipping documents are submitted, effectively preventing default risks for both parties in cross-border transactions.
    Application scenarios: Chinese machinery manufacturers often adopt letters of credit when exporting equipment to buyers in Europe and the United States.

    Factoring

    Plain explanation: Enterprises transfer accounts receivable from downstream clients to financial institutions to receive payment in advance. The financial institution will then collect outstanding payments from debtors, helping enterprises revitalize outstanding funds.

    Section 5: Macroeconomics & Risk Control (Essential Terms for Understanding Global Financial News)

    CPI (Consumer Price Index) / Inflation

    Plain explanation: CPI tracks price changes of daily consumer goods and services. A continuous rise in CPI signals inflation, which reduces purchasing power as the same amount of money can buy fewer goods.
    Application scenarios: In high-inflation environments, households tend to allocate assets to real estate, commodities and equity products to hedge against currency depreciation.

    Spot Exchange Rate & Forward Exchange Rate

    Plain explanation: The spot exchange rate refers to the real-time price for immediate foreign currency conversion; the forward exchange rate locks in an exchange rate for currency exchange scheduled on a specific future date.
    Application scenarios: Foreign trade enterprises lock forward exchange rates to avoid revenue losses caused by exchange rate fluctuations.

    Monetary Policy

    Plain explanation: Central banks adjust interest rates, reserve requirement ratios and other tools to regulate the total money supply in the market, aiming to curb inflation or stimulate economic growth.

    Foreign Exchange Reserves

    Plain explanation: National holdings of foreign currencies, gold, overseas bonds and other assets, used to stabilize domestic exchange rates, guarantee cross-border debt repayment and balance international trade.

    Financial Leverage

    Plain explanation: Borrowing external capital to expand the scale of investment with personal funds. It magnifies potential returns while simultaneously increasing the risk of investment losses.

    Section 6: Advanced Financial Derivatives (Commonly Used for Corporate Risk Hedging and Institutional Investment)

    Futures

    Plain explanation: Standardized contracts signed by two parties to trade commodities, stock indices, foreign exchange and other underlying assets at a fixed price on a future date. Futures can be used for speculative trading or to hedge against price volatility of raw materials.

    Options

    Plain explanation: Investors pay a small premium to obtain the right to buy or sell specified assets at an agreed price in the future. The maximum loss is limited to the premium paid, making options far less risky than futures.

    Hedging

    Plain explanation: Enterprises use derivatives such as futures and forward contracts to lock in raw material procurement costs or product export prices, offsetting operational risks triggered by drastic market price swings.

  • New Advances in Cancer Research from Guangxi Medical University: Innovative Therapeutic Strategies to Conquer Treatment Resistance

    Introduction

    Cancer remains one of the most severe global public health challenges. Traditional mainstream cancer treatments including radiotherapy, chemotherapy and targeted therapy often face a common bottleneck: treatment resistance. Once cancer cells develop tolerance to conventional therapies, patients will suffer from disease progression and poor survival outcomes. To break this dilemma, research teams from multiple affiliated hospitals of Guangxi Medical University have launched in-depth explorations on three prevalent malignant tumors—nasopharyngeal carcinoma, glioma and EGFR-mutant non-small cell lung cancer. A series of innovative therapeutic schemes have been verified through preclinical experiments and multicenter clinical trials, with relevant research findings published in top international academic journals. These studies provide feasible new treatment directions for patients with drug-resistant cancers worldwide. This article systematically sorts out these latest research breakthroughs and interprets core professional medical terms for global readers.

    1. Engineered Exosome Delivery System Helps Reverse Radiation Resistance in Nasopharyngeal Carcinoma

    Nasopharyngeal carcinoma is a highly prevalent malignant tumor in South China and Southeast Asia. Radiotherapy serves as the first-line treatment for this disease, yet nearly 30% of patients eventually develop radiation resistance, which directly leads to treatment failure.

    A research group from the First Affiliated Hospital of Guangxi Medical University clarified a key pathogenesis of radiotherapy resistance in nasopharyngeal carcinoma. The overexpression of the SP1 protein can induce the abnormal proliferation of tumor blood vessels. These deformed blood vessels build a protective barrier for cancer cells, greatly weakening the killing effect of radiation on tumor tissues.

    To break this protective shield, the research team developed an engineered exosome delivery system. As a kind of biological nanoparticle carrier, engineered exosomes can accurately transport inhibitory drugs to abnormal tumor blood vessels without damaging normal human tissues. After repairing the structure of tumor blood vessels, radiotherapy can regain its expected anti-tumor efficacy. Compared with traditional systemic chemotherapy, this targeted delivery method effectively reduces adverse side effects on healthy organs and tissues, bringing new treatment hopes to patients with recurrent and radiation-resistant nasopharyngeal carcinoma.

    2. Intermittent Fasting: An Economical Adjuvant Treatment for Glioma

    Glioma is an aggressive intracranial malignant tumor with limited available treatment options. Conventional surgery combined with chemoradiotherapy often brings heavy economic burdens and severe physical side effects to patients. Therefore, exploring low-cost and safe auxiliary treatment methods has long been a research hotspot in neuro-oncology.

    A research team from the Institute of Life Sciences of Guangxi Medical University has published relevant research results in a sub-journal of Nature. The study confirmed that intermittent fasting exerts subtype-specific anti-tumor effects on Tp53 mutant glioma. By regulating the composition of intestinal flora and methionine metabolism in the human body, intermittent fasting changes the level of N⁶-methyladenosine (m⁶A) RNA methylation, further inhibits the overactivation of the TGF-β tumor-promoting signaling pathway, and significantly slows the proliferation and invasion of glioma cells.

    This research provides reliable experimental evidence for non-drug adjuvant anti-cancer therapy. As an easy-to-implement intervention method, intermittent fasting can be combined with standard clinical treatment regimens to improve the prognosis of glioma patients while controlling medical costs.

    3. Targeted Combined Chemotherapy Optimizes Survival Outcomes of EGFR-Mutant Lung Cancer Patients

    EGFR mutation is the most common gene variation in non-small cell lung cancer. For patients with concurrent tumor suppressor gene co-mutations, single targeted therapy often fails to achieve long-term disease control.

    Researchers from the Affiliated Cancer Hospital of Guangxi Medical University participated in a global multicenter clinical trial, whose research paper was published in CA: A Cancer Journal for Clinicians, the highest-impact journal in the field of oncology. The trial data proved that compared with single targeted drugs, the combined regimen of targeted therapy and chemotherapy can significantly prolong progression-free survival and overall survival for this group of lung cancer patients.

    This research revises the previous single-drug treatment strategy for EGFR-mutant lung cancer with complex gene variations and forms a standardized precision treatment reference scheme for clinical oncologists around the world.

    Glossary of Core Medical Terms

    1. Engineered Exosome Delivery System: Manually modified tiny biological carriers that can accurately transport anti-tumor drugs to lesion sites to achieve targeted treatment and reduce systemic side effects.
    2. Radiation Resistance: A biological state in which tumor cells adapt to radiation damage, resulting in significantly reduced radiotherapy efficacy.
    3. Intermittent Fasting: A nutritional intervention strategy with periodic food restriction, applied as an auxiliary anti-tumor treatment in this study.
    4. N⁶-methyladenosine (m⁶A): The most common epigenetic modification on messenger RNA, which can regulate tumor cell proliferation, metastasis and drug resistance.
    5. Immune Checkpoint Inhibitor: A type of anti-cancer drug that reactivates the body’s own immune system to recognize and attack cancer cells.
    6. Targeted Combination Chemotherapy: A treatment mode combining targeted drugs acting on specific cancer gene sites and traditional chemotherapeutic drugs to overcome tumor drug resistance.
    7. Transarterial Chemoembolization (TACE): A minimally invasive local treatment for malignant tumors, which cuts off the blood supply of tumors and locally releases anti-cancer drugs to kill cancer cells.

    Conclusion

    The three cancer research achievements from Guangxi Medical University focus on the most tricky clinical pain point—treatment resistance. From precise nanoparticle drug delivery and low-cost nutritional auxiliary intervention to optimized combined medication schemes, these studies enrich the global arsenal of anti-cancer therapies from multiple dimensions of precision medicine, translational medicine and clinical treatment.

    Medical science is a global collaborative cause. All the above research results are based on international academic communication and cross-regional data cooperation. The research team expects to carry out deeper joint research, clinical trial cooperation and academic exchanges with medical institutions, biopharmaceutical enterprises and scientific research institutions from all over the world. Through open scientific cooperation, these innovative anti-cancer strategies can be continuously optimized, accelerated to clinical transformation, and bring survival benefits to cancer patients in every region of the world.

  • Time Scaling: A System-Oriented New Paradigm for Post-Moore Semiconductor Development

    1. The Historical Track and Bottleneck of Moore’s Law

    Put forward by Gordon Moore in 1965, Moore’s Law has guided the semiconductor industry for over half a century. By geometrically scaling down transistor linewidth from 90nm, 28nm to the current 3nm and 2nm advanced nodes, the industry realized sustained performance improvement.

    Nevertheless, continuous geometric miniaturization is gradually reaching physical boundaries. The investment cost of advanced process fabs has surged exponentially, thermal dissipation challenges become prominent, and the performance improvement brought by each new generation of process technology keeps diminishing. The whole industry is urgently seeking diversified sustainable innovation paths to meet the explosive growth demand of computing capacity from cloud computing, artificial intelligence and data centers.

    2. Core Principle of Time Scaling Innovation

    Time constant τ (tau) describes the required duration for electrical signals to switch status and transmit across circuits, which determines the response speed of electronic devices. Different from the traditional method of indirectly reducing τ by shrinking transistor size, time scaling regards the optimization of τ as the direct core goal of technological iteration.

    It builds a multi-level collaborative optimization framework covering device, circuit, chip and system layers:

    • At the device layer: Optimize the switching speed of single transistors and reduce parasitic resistance and capacitance of metal interconnects;
    • At the circuit layer: Shorten critical signal transmission paths and streamline circuit layout design;
    • At the chip layer: Optimize the collaborative scheduling of computing units, cache and on-chip networks to avoid invalid data migration;
    • At the system layer: Upgrade inter-chip and server communication protocols to cut synchronization and waiting latency among multiple hardware devices.

    This technical paradigm evolves from the System-Technology Co-Optimization (STCO) methodology widely adopted in the chip design field. By matching optimal manufacturing processes and interconnection technologies for different functional modules, the whole computing system can reach the best overall efficiency. Relevant theoretical research points out that systematic time scaling optimization is expected to deliver equivalent computing density performance matching 1.4nm advanced process nodes through architectural and system innovation.

    3. Global Industrial Value and Cooperation Prospect

    Time scaling reshapes the evaluation standard of semiconductor technological progress: the industrial focus shifts from how tiny transistors can be manufactured to how fast the whole computing system can respond.

    For the global industrial chain, this paradigm diversifies technological development options. Enterprises no longer have to participate in fierce advanced process competition relying on high-end lithography equipment. Advanced packaging, chip architecture innovation and software-hardware co-design become core competitive advantages, offering emerging market participants a feasible breakthrough route.

    This innovative technological direction requires open global collaboration. From academic research to industrial technical verification, researchers, engineers and enterprises from all regions can jointly polish relevant theories, iterate technical solutions, and build a more diversified, resilient and sustainable global semiconductor industrial ecosystem.
