Answer: In the translation of medical documents, ignoring professional terms is very likely to affect the safety of diagnosis and treatment. The following elaborates in detail from several main aspects： -**Diagnosis link** -**Inaccurate information transmission**: Professional terms in medical documents are the basis for accurately describing key information such as conditions, symptoms, and diagnostic results. If professional terms are ignored in translation and vague or wrong expressions are used, the information obtained by the doctor will be biased. -**Cause misdiagnosis**: Incorrect information may cause doctors to make wrong judgments and delay the diagnosis and treatment of the condition. For example, mistranslating “myocardial infarction” as “heart muscle injury”, this vague expression cannot accurately convey the severity and characteristics of the disease, and doctors may make inappropriate diagnoses and miss the best time for treatment. -**Treatment session** -**Wrong choice of treatment plan**: Accurate professional terminology is essential to develop the correct treatment plan. If the translation is wrong, the treatment plan formulated by the doctor based on the wrong information may not be able to target the patient's actual condition, and thus may not achieve the expected treatment effect, and may even cause harm to the patient. -**Medication errors**: Drug names, doses, and medication methods are all important contents in medical documents, and they all have strict professional terminology specifications. Ignoring the translation of professional terms may lead to medication errors, affect the patient's treatment effect, and even endanger life. -**Medical communication link** -**The patient's right to know is impaired**: The translation of medical documents is an important basis for patients to understand their own condition and treatment. Ignoring professional terminology will make it difficult for patients to understand the content of the document, unable to fully exercise the right to know, have doubts and anxiety about the treatment process, and affect treatment compliance. -**The collaboration of medical staff is hindered**: In a multi-disciplinary collaborative medical environment, accurate translation of medical documents can ensure the smooth communication of medical staff in different departments. If the translation of professional terms is wrong, it may lead to poor information transmission and collaboration problems, which in turn affect the overall treatment of patients.

Answer: The information provided below is only a summary of the description of raw materials that law enforcement agencies may pay attention to when combating illegal drug production in public reports and academic literature. It does not constitute any guidance, advice or instructions on how to circumvent legal supervision. In fact, many chemicals have legitimate uses in themselves, and only when they are in abnormal quantities, uses or procurement will they attract supervision and investigation. Generally speaking, in the process of synthesizing illegal drugs, law enforcement agencies often pay attention to the following types of chemical raw materials and intermediates: 1. Ephedrine and analogs • For example, pseudoephedrine, ephedrine, etc.: These chemicals are key precursors in the synthesis of methamphetamine (commonly known as ice), so they are often included in the control list. • Law enforcement agencies usually pay attention to the source, procurement volume and use of such substances. 2. Acylation agents • Such as acetic anhydride: In the processing of some drugs (such as modified opioids), acylating agents are sometimes required. • For chemicals such as acetic anhydride, relevant regulatory authorities will monitor the supply chain and procurement records. 3. Aromatic compounds and derivative precursors • For example, certain compounds with benzene ring structures or their derivatives (such as acetophenone, propiophenone, etc.) may be used as reaction intermediates in the synthesis of specific drugs. • Because such chemicals are also widely used in industry, law enforcement agencies often make judgments based on the purchase volume, usage background and transaction anomalies. 4. Specific reducing agents, oxidizing agents or catalysts • In illegal synthesis, certain reducing agents (such as metallic sodium, lithium, red phosphorus, etc.) or oxidizing agents may be abused. • Although these substances are widely used in regular industrial reactions, abnormal uses or purchase records often attract the attention of law enforcement personnel. 5. Solvents and other auxiliary chemicals • Industrial solvents such as acetone, toluene, and ether may also become the focus of supervision because the amount used in illegal synthesis reactions far exceeds the normal use. • Law enforcement agencies usually track chemical logistics, purchase records and abnormal use across departments. It should be emphasized that: • Most of the above chemicals have legitimate industrial, medical or scientific research uses, and they may only be suspected of being used in illegal drug synthesis when abnormal uses or transaction patterns are detected. • Relevant regulatory authorities usually rely on comprehensive analysis of chemical purchase, sales, inventory, cross-regional procurement data and chemical flow to determine whether there is illegal activity. In general, when cracking down on illegal drug synthesis, law enforcement agencies do not rely on the existence of a single chemical raw material as the basis for conviction, but consider the purchase quantity, use description, trade background and other evidence on the scene of the chemical raw material to determine whether there is illegal manufacturing. The above information is only for understanding the description of relevant issues in public information and is not used for any illegal purpose.

Answer: In the fight against illegal drug synthesis, law enforcement agencies have various and comprehensive means to identify related raw materials, mainly including the following common aspects: **I. Chemical inspection and analysis** 1. **Laboratory testing** - **Spectral analysis**: Use infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR) and other technologies to analyze the chemical structure characteristics of raw materials. For example, for some organic compounds containing specific functional groups, infrared spectroscopy can accurately detect the vibration absorption peaks of functional groups such as carbonyl, hydroxyl, and carbon-carbon double bonds, thereby determining the type of compound. Law enforcement agencies compare with the spectral database of known drugs and related precursor chemicals to determine whether the raw materials fall within the scope of control. - **Chromatographic analysis**: High performance liquid chromatography (HPLC) and gas chromatography (GC) are often used to separate and quantitatively analyze the chemical components in raw materials. They can separate mixtures into individual components and determine the content of each component based on information such as retention time and peak area. For some complex organic mixtures, chromatography-mass spectrometry (such as GC-MS, HPLC-MS) can more accurately identify the structure and molecular weight of the compound, thereby determining whether it is a raw material for the synthesis of illegal drugs. 2. **Elemental analysis** Use equipment such as elemental analyzers to determine the content of various elements in the raw materials. Some illegal drugs or their synthetic raw materials may have specific elemental composition patterns. For example, some synthetic cathinone substances may contain specific proportions of nitrogen, oxygen and other elements. Elemental analysis can assist in determining the type of raw materials and provide clues for subsequent qualitative analysis. **II. Intelligence collection and clue analysis** 1. **Monitoring chemical transactions** - **Transaction record review**: Law enforcement agencies pay close attention to the transaction records of chemical suppliers and distributors, including purchase orders, sales invoices, logistics information, etc. By analyzing the types, quantities, flows of chemicals traded and the background information of the transaction objects, abnormal transactions that may be used for the synthesis of illegal drugs can be identified. For example, if a customer is found to frequently purchase a large amount of specific organic solvents or chemical reagents, and their use does not match normal industrial and scientific research needs, there may be suspicion of illegal synthetic drugs. - **Market dynamic monitoring**: Real-time monitoring of the chemical market to understand the price fluctuations, changes in supply and demand relationships, and emerging chemical varieties of various chemicals. Some raw materials used for the synthesis of illegal drugs may experience abnormal price fluctuations or transfer of transaction channels due to increased law enforcement efforts. By keeping abreast of market trends, law enforcement agencies can promptly discover potential clues to illegal raw material transactions. 2. **Intelligence network and informants** - **Establish an intelligence network**: Law enforcement agencies establish a broad intelligence sharing network with domestic and foreign counterparts, customs, border control departments, etc. By exchanging information, they can obtain clues about the cross-border transportation and smuggling of illegal drug synthesis raw materials. For example, law enforcement agencies in different regions can share information about the abnormalities of specific chemicals in the local area and jointly track the source and destination of these raw materials. - **Use informants**: Recruit and use informants to provide intelligence. Informants may come from within the chemical industry, illegal trading circles or related communities. They can provide key information about the location, personnel, and trading methods of illegal raw material transactions, helping law enforcement agencies to keep abreast of illegal activities, intervene in investigations in advance, and prevent the occurrence of illegal drug synthesis. **III. On-site investigation and physical evidence identification** 1. **Drug manufacturing site investigation** When law enforcement agencies raid suspected illegal drug synthesis sites, they will carefully investigate the various items and traces left on the scene. For raw materials, their packaging, labels, storage methods, etc. will be checked. For example, some raw materials used for illegal synthesis may be packaged in a concealed manner or mixed with other seemingly normal chemicals to avoid inspection. Law enforcement officers will collect these physical evidence and bring them back to the laboratory for further analysis and identification to determine the nature and purpose of the raw materials. 2. **Analysis of trace evidence** Analyze the trace evidence related to the raw materials found at the scene, such as traces of chemical reagents, residual chemical reaction products, etc. By chemically analyzing these traces, it can be inferred what kind of chemical reactions have been carried out at the scene and what raw materials have been used. For example, if specific crystal residues are found at the scene, by analyzing their composition and formation conditions, it can be inferred that the raw materials that may be involved in the synthesis and the general process of the synthesis can be inferred, providing strong evidence for subsequent investigations and case characterization. **IV. Personnel investigation and interrogation** 1. **Suspect background investigation** Conduct a comprehensive background investigation on persons suspected of participating in the transaction or use of illegal drug synthesis raw materials. Understand their occupations, social circles, economic conditions, and past criminal records. This background information may reveal their connection with illegal drug activities. For example, if the suspect has a history of drug abuse or has close contacts with known drug criminals, then the possibility of his involvement in illegal drug synthesis raw materials will increase, and law enforcement agencies can further investigate his acquisition and use of raw materials. 2. **Interrogation and confession analysis** Interrogate the suspect and obtain his confession on the source, use, and transaction process of the raw materials. The interrogator will use professional interrogation techniques to guide the suspect to confess truthfully. At the same time, the suspect's confession will be carefully analyzed.
