Abstract
This clinical value-oriented comprehensive evaluation of drugs was carried out in accordance with Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021), with the qualitative and quantitative evaluation methods adopted. Based on the evidence-based medicine, epidemiology, clinical medicine, pharmacoeconomics, mathematical statistics, and health technology evaluation(HTA), the clinical value of Ginkgolide Injection was evaluated from the "6+1" dimension by giving weight to the criterion level and index level and calculating with multi-criteria decision analysis(MCDA) model and CSC v2.0. After entering the market, Ginkgolide Injection has been subjected to phase Ⅳ clinical trial, spontaneous reporting system(SRS)-based data monitoring, systematic review and Meta-analysis, acute toxicity and long-term toxicity assays, active monitoring, and RCTs, and the evidence of safety was sufficient. The results of active monitoring showed that the incidence of adverse reactions was 0.09%(rare), mainly manifested as flushing, dizziness, rash, nausea, and vomiting. According to the nested case-control study, the adverse reactions of this drug had nothing to do with the product batch, implying that the drug quality was controllable. The adverse reactions mainly resulted from the pharmacodynamic reactions. Because the drug was effective in resisting platelet aggregation, the resulting adverse reactions such as flushing, dizziness, headache, and phlebitis were caused by vasodilation. Skin rash and gastrointestinal symptoms were mainly attributed to the patients' sensitivity to drugs and their own allergic constitution. According to the sufficiency of evidence and the incidence of adverse reactions in the safety research, the safety of Ginkgolide Injection was grade A. The results of Meta-analysis showed that Ginkgolide Injection combined with conventional western medicine was superior to conventional western medicine in improving the clinical effective rate, neurological function score, and activity of daily living score of patients with cerebral infarction. The validity evidence was evaluated according to the PICO principle to be high. According to the GREAD evaluation principle, the quality of such evidence as clinical effective rate, National Institute of Health stroke scale(NIHSS), and Barthel Index(BI) was evaluated, and the results demonstrated that the evidence quality of clinical effective rate and activity of daily living score was medium. The effectiveness of Ginkgolide Injection was grade A. According to the economic report of Ginkgolide Injection, it had short-term and long-term pharmacoeconomic advantages in the treatment of ischemic stroke, and the economic evidence value was good. According to the CASP economic evaluation checklist, the overall quality evaluation results of the economic report are basically clear. To be specific, the economic evidence quality was high. Based on the comprehensive economic evidence quality and economic value, the economy of this drug was grade A. The innovation of this product was evaluated from three aspects: clinical innovation, enterprise service system innovation, and industrial innovation. Ginkgolide Injection could be used 24 h after intravenous thrombolysis for improving patients' neurological function without increasing bleeding, indicating its important clinical innovation. There were many innovations in ensuring drug supply, especially at the grass roots, drug safety, effectiveness, and reasonable price, which has provided reference for establishing enterprise philosophy, managing drug resources, developing process and technology, and determining enterprise management and marketing. Therefore, its innovation was grade A. The drug had no special medication plan in use, exhibiting good suitability for doctors, nurses, and patients. The suitability was grade B. Compared with similar drugs, its price was at a medium level, meaning good affordability, sufficient production capacity, and easy accessibility. Its accessibility was therefore grade B. This drug belonged to Chinese medicinal injection. The large-sample real-world research revealed rich human use experience, so it was grade C for the traditional Chinese medicine characteristic. According to the comprehensive evaluation, the clinical value of Ginkgolide Injection in the treatment of cerebral infarction fell into class A.

Abstract
The clinical comprehensive evaluation of drugs is an important basis for the return of clinical value, decision-making of medical and health authorities, and allocation of medical resources. In July 2021, the National Health Commission issued the Guidelines for the Management of Clinical Comprehensive Evaluation of Drugs(trial version 2021), which required the evaluation to be implemented from the six dimensions(safety, effectiveness, economy, innovation, suitability, and accessibility), and made detailed arrangements for the clinical comprehensive evaluation of drugs. As Chinese patent medicine differs from chemical medicines in terms of effective components and action modes, the clinical comprehensive evaluation of Chinese patent medicine should highlight the characteristics and advantages of traditional Chinese medicine(TCM) on the basis of general requirements of comprehensive clinical evaluation of drugs. At present, in the clinical comprehensive evaluation of Chinese patent medicine, unified report standards have not yet been generated, resulting in the uneven quality of existing reports. To standardize the clinical comprehensive evaluation report of Chinese patent medicine and improve its quality, the editorial team, based on the relevant policy documents of clinical comprehensive evaluation of drugs, formulated the clinical comprehensive evaluation report standards for Chinese patent medicine in combination with the previous practice and expert opinions. The report standards, containing seven sections with 15 items determined, focus on data source, evaluation content, evidence synthesis, quality control, and evaluation results supported with detailed interpretations to help researchers better understand and apply the report standards for clinical comprehensive evaluation of Chinese patent medicine, improve the report quality, and provide references for the decision-making by the national medical management authorities.

Abstract
The safety of modern Chinese medicine has attracted increasing attention from society. Experts and scholars have carried out extensive in-depth research on the safety of commonly used Chinese medicines from various aspects such as safety monitoring, clinical research, and experimental analysis. The findings in the safety performance of Chinese medicines can inspire the mining and analysis of relevant signals in the drug safety alerts. A variety of methods are employed for the mining of risk signals or analysis and screening of relevant signals to accurately determine the correlation between medication and adverse reactions. The safety signal acquisition and mining techniques are the technical basis for the safety risk management of medicine products after Chinese medicines are marketed, which is critical in drug safety alerts. To accurately collect the safety signals of Chinese medicines and effectively and rapidly track, determine, and assess the sources of signals are important technical links in drug risk management. The ultimate purpose of safety signal discovery is to achieve normalized risk management through downgrading drugs from a high-risk level to a low-risk level.The five main steps in the standard drug risk management are listed below: to extensively collect predicted risk signals; to accurately identify drug risks by the techniques such as data mining; to evaluate the risks with process-based quality risk control; to employ management measures minimizing the impact of drug risks for risk management; to update and apply risk assessment to clinical evaluation after medication.

Abstract
To explore the immune status of patients with drug-induced liver injury caused by Polygonum multiflorum preparations,and analyze their immune characteristics. Case-control design was used to collect the cases of drug-induced liver injury caused by P. multiflorum preparations through key specialized surveillance. Five matching factors,namely type of P. multiflorum preparations,gender,age,basic diseases and concomitant medication were controlled. According to the ratio of 1 ∶ 1,cases of patients who took P. multiflorum preparations but with no liver injury were monitored at prospective hospitals. The demographic information,disease information,medication information and laboratory examination information of the two groups were recorded,and venous blood was collected. The gene sequence was detected by high-throughput sequencing technology,and the characteristics of TCR immune repertoire of the two groups were analyzed. A total of 46 pairs of patients were enrolled in the study. The results showed significant differences in the number of CDR3 and clone species,the length of amino acid sequence in CDR3 region,the abundance of V gene and J gene,the cross-linking of V-J gene and the diversity of immune repertoire between patients with drug-induced liver injury and patients without liver injury. The immunohistochemical diversity and high-frequency V-J cross-linking characteristics of patients with liver injury caused by P. multiflorum preparations were found,which provided a reference for screening out drug users to reduce the occurrence of liver injury caused by P. multiflorum preparations.

Abstract
Objective: To identify the therapeutic efficacy of lithium chloride (LiCl) on phosphatase and tensin homolog deleted on chromosome ten (PTEN)-deficient tumors. Methods: First, the Catalogue of Somatic Mutations in Cancer for mutation spectrum of human endometrial carcinoma samples was analyzed. Second, the relationship between PTEN abundance and LiCl inhibition of endometrial cancer cell lines using Pten(+/+) and Pten(-/-) mouse embryonic fibroblast (MEF) lines was investigated. Moreover, potential alterations of mammalian target of rapamycin (mTOR) signaling pathway after treatment with LiCl were checked.Last,LiCl's efficacy on PTEN null tumors was studied. Results: PTEN was mutated in 39% of endometrial carcinomas. LiCl preferentially inhibited the proliferation of PTEN-deficient endometrial carcinoma cells and MEFs. Furthermore, LiCl blocked PTEN-deficient tumor development. Mechanistically, LiCl down-regulated mTOR signaling. Conclusions: PTEN is the most frequently mutated gene in endometrial carcinoma.By targeting mTOR signaling pathway,LiCl is a promising regimen for the treatment of tumors with PTEN deficiency.

Abstract
A consequent tendency toward high-performance quantum information processing is to develop the fully integrated photonic chip. Here, we report the on-chip generation and manipulation of entangled photons based on reconfigurable lithium-niobate waveguide circuits. By introducing a periodically poled structure into the waveguide circuits, two individual photon-pair sources with a controllable electro-optic phase shift are produced within a Hong-Ou-Mandel interferometer, resulting in a deterministically separated identical photon pair. The state is characterized by 92.9±0.9% visibility Hong-Ou-Mandel interference. The photon flux reaches ∼1.4×10(7) pairs nm-1 mW-1. The whole chip is designed to contain nine similar units to produce identical photon pairs spanning the telecom C and L band by the flexible engineering of nonlinearity. Our work presents a scenario for on-chip engineering of different photon sources and paves the way to fully integrated quantum technologies.

Abstract
Anti-Stokes/Stokes asymmetries under surface enhanced Raman scattering (SERS) conditions are studied for a wide variety of SERS-active media and different analytes. Evidence is provided for the existence of underlying resonances that create these asymmetries. We show here that these resonances are associated with the electromagnetic coupling between the analyte (probe) and the metal. The work demonstrates the use of the anti-Stokes/Stokes ratio as a tool to understand the hierarchy of resonances in the SERS problem, which is essential for quantification purposes.

Abstract
A novel mechanism of H0 and strangelet production in hadronic interactions within the Gribov-Regge approach is presented. In this approach the H0 is produced by the same mechanism as usual hadrons, namely, by disintegration of the remnant formed by the exchange of pomerons between the two protons. Rapidity and transverse momentum spectra of the observed hadrons are well described in this approach. In contrast to traditional distillation approaches, here the production of multiple (strange) quark bags does not require large baryon densities or a quark gluon plasma. We calculate the rapidity and transverse momentum distributions as well as the 4pi multiplicity of the H0 for sqrt[s]=17 GeV (Super Proton Synchrotron) and 200 GeV (Relativistic Heavy Ion Collider). In both cases the H0, if it exists, should be observable by the present experiments.

Abstract
The Omega/Omega ratio originating from string decays is predicted to be larger than unity in proton-proton interactions at SPS energies ( E(lab) = 160 GeV). The antiomega dominance increases with decreasing beam energy. This surprising behavior is caused by the combinatorics of quark-antiquark production in small and low-mass strings. Since this behavior is not found in a statistical description of hadron production in proton-proton collisions, it may serve as a key observable to probe the hadronization mechanism in such collisions.

Abstract
A water-soluble polysaccharide, RHG, was isolated from the roots of Hedysarum polybotrys Hand.-Mazz. It was shown to be homogeneous by electrophoresis and gel filtration. Its average molecular weight was estimated to be 1.4 x 10(4). Methylation analysis, periodate oxidation, Smith degradation, IR, NMR and KI-I2 reaction showed that RHG is a (1-4) linked alpha-D-glucan to which the glucosyl side chains are attached at O-6 of the glucosyl residues of the main chain.

Abstract
The effect of captopril cardioplegia on ischemic and reperfusion myocardium after 3 hours of hypothermic (13 +/- 1 C) arrest and 35 minutes of reperfusion was studied in the isolated working rabbit heart. In comparison with the control group, captopril cardioplegia reduced the content of angiotensin II (381 +/- 56 vs 507 +/- 84 pg/g wt of the control group, P < 0.01) and MDA (50.0 +/- 9.2 vs 85.1 +/- 16.1 pmol/mg pr, P < 0.01) in the reperfusion myocardium; augmented the renin activity of ischemic (1050 +/- 353 vs 669 +/- 301 pg/g wt/h, P < 0.05) and reperfusion myocardium (1261 +/- 421 vs 498 +/- 353 pg/g wt/h, P < 0.01) increased the 6-K-PGF1 alpha/TXB2 ratio in the reperfusion myocardium (by 48.1% of the control group). Meanwhile, captopril cardioplegia could also decrease the content of calcium (0.027 +/- 0.015 vs 0.045 +/- 0.014 microM/mg pr, P < 0.05) and sodium (0.54 +/- 0.26 vs 0.82 +/- 0.15 microM/mg pr, P < 0.05) in the reperfusion myocardium, but had no effect on the potassium content. The results show that the protective effect of captopril on hypothermic myocardium may be related to the free radical scavenging action, inhibition of angiotensin II production, improvement of PGI2/TXA2 ratio and decrease of calcium and sodium overload in the myocardium.

Abstract
The myocardial protective effect of captopril cardioplegia was investigated through the recovery of cardiac functions, biochemical changes and ultrastructural assays in the isolated working rabbit heart after hypothermic ischemic arrest for 3 hours. Hearts were randomly divided into 3 groups with 8 in each. Another 3 groups of hearts (8 in each) were arranged for studying the biochemical changes and ultrastructure during the ischemic period. In the control group (I), the hearts were protected by the modified St. Thomas' cardioplegic solution No. I, while in Group II and III the cardioplegic solutions contained 2.3 mumol/L and 23 mumol/L captopril respectively. The results showed that the percent recoveries of cardiac function in the 23 mumol/L captopril group compared with the control group were 97.9 +/- 9.8% vs 84.9 +/- 7.3% in left ventricular peak systolic pressure (P less than 0.01), 118 +/- 33% vs 79 +/- 20% in +dp/dt max (P less than 0.01), 111 +/- 22% vs 75 +/- 18% in -dp/dt max (P less than 0.01), 145.6 +/- 44.8% vs 76.7 +/- 18% in coronary flow (P less than 0.01), 120.2 +/- 45.7% vs 36.4 +/- 22.2% in aortic flow (P less than 0.01), 127.4 +/- 27.3% vs 56.1 +/- 14% in cardiac output (P less than 0.01), and 118.2 +/- 33.5% vs 52.5 +/- 19.9% in stroke volume (P less than 0.01) respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Bile acid extracts were prepared from grass carp, bighead, common carp, milk fish and tilapia. Injection of the fish bile extracts (3.6 mg/kg, i.v.) into rats increased renal excretion of water, sodium and potassium; decreased blood pressure; and hemolyzed RBCs. The diuretic, natriuretic, hypotensive and hemolytic actions of the bile extracts were stronger in grass carp, bighead and common carp, moderate in milk fish, and weakest in tilapia.

Abstract
It was demonstrated recently that a local renin-angiotensin system (RAS) exists in the heart and coronary vessels, and the angiotensin converting enzyme inhibitors can protect the heart from ischemia. Eight patients with NYHA class II-IV subjected to valve replacement were studied in protecting the heart from global ischemia with captopril during open heart surgery. After the ascending aorta was clamped, 500-1000 ml 4 degrees C modified St. Thomas No 1 cardioplegic solution containing 0.058-0.23 mmol/L captopril was perfused into coronary arteries under pressure until the electrocardiogram showed disappearance of myocardial electroactivity. The cardioplegic perfusion was repeated every 30 minutes thereafter during cardiopulmonary bypass (CPB). All the hearts rebeat after reperfusion either spontaneously or from defibrillation without any trouble. Three patients developed an A-V dissociation which returned to sinus rhythm or atrial fibrillation after a tiny dose of dopamine or isoprenaline intravenously. All the patients weaned from the CPB easily with a stable heart rate and a reasonable MAP. None of them needed inotropic support, even those with severe heart failure before operation did not either, and all recovered uneventfully.
