ABSTRACT
Malignant tumors have surpassed stroke and coronary heart disease to become the main cause of death before the age of 70 in the world. The incidence of malignant tumors is increasing year by year， which seriously affects the living standards and social and economic development of Chinese people. Surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy are the main means of Western medicine to intervene in tumors， which are of great significance for prolonging the survival time of patients. However， there are many disadvantages such as adverse reactions and drug resistance. Traditional Chinese medicine has become a research hotspot in recent years because of its definite curative effect and wide application in tumor treatment. Xiao Chaihutang is derived from the Treatise on Febrile and Miscellaneous Diseases. It is composed of Bupleuri Radix， Scutellariae Radix， Ginseng Radix， Pinelliae Rhizoma， Glycyrrhizae Preparata Radix， Ginger， and Jujube. It has the effects of reconciling Shaoyang， reconciling cold and heat Yin and Yang， soothing the liver， and relieving depression. This prescription and the prescriptions based on it are widely used in various stages of tumors. This study summarized the Chinese and foreign research of Xiao Chaihutang in the field of tumors in the past 10 years and explored the role and mechanism of Xiao Chaihutang in blocking precancerous lesions， controlling the development of malignant tumors， reducing the occurrence of adverse reactions after intervention， and alleviating common complications， with a view to expanding the clinical medication ideas.
ABSTRACT
Objective To investigate the expression level and diagnostic value of serum DNA polymerase α(DNA pol α)in Alzheimer's disease(AD),and analyze its diagnostic efficacy in AD.Methods A total of 100 patients of dementia of Alzheimer's type(DAT)and 43 patients of mild cognitive impairment(MCI)from Xuanwu Hospital Capital Medical University from March 2019 to April 2023 were included in this study,and 68 healthy individuals of the same age group were collected as the HC group.The expression level of DNA pol α was detected in each group,and the diagnostic value of DNA pol α in AD was analyzed by receiver oper-ating characteristic(ROC)curve.Results The expression level of DNA pol α in DAT group was higher than those in the MCI group(P＜0.05)and the HC group(P＜0.001).The expression level of DNA pol α showed an increasing trend as AD progressed.The expression level of DNA pol α was negatively correlated with Mini Intelligent Mental State Examination Scale(MMSE)score and Montreal Cognitive Assessment Scale(MoCA)score(r=-0.155 3,-0.203 7,P＜0.05).The area under the curve(AUC)of DNA pol α for diagnosing DAT was 0.682,and the sensitivity was 0.900.The AUC for diagnosing MCI was 0.546,and the sensitivity was 0.977.The AUC for differential diagnosis of MCI and DAT was 0.664,the sensitivity was 0.780,and the specificity was 0.535.Conclusion The expression level of DNA pol α is significantly increased in AD patients with DAT,and its expression level is related to the progression of AD,suggesting that DNA pol α has the pos-sibility to be a potential blood biomarker for the diagnosis of AD.
ABSTRACT
Objective To study the effect of NAD(P)H:quinone oxidoreductase 1(NQO1)expression lev-el on prognosis in patients with hepatitis B virus-related hepatocellular carcinoma(HBV-HCC).Methods A total of 103 patients with HBV-HCC underwent surgical treatment in Seventh People's Hospital of Shanghai University of Traditional Chinese Medicine from March 2019 to January 2020 were enrolled.The cancer tissue and adjacent normal tissues were extracted during surgery.Immunohistochemical staining was used to detect the expression of NQO1 in tissues.The clinical and pathological data of patients were collected,and the rela-tionships between high and low expression of NQO1 and pathological characteristics were discussed.A 3-year follow-up was conducted,and the Kaplan-Meier survival curve was drawn and Log-rank test was conducted on median survival time.Then COX model analysis was used to analyze the factors affecting the prognosis of HBV-HCC patients.Results The positive rate of NQO1 in HBV-HCC tissues was 84.47％(87/103)and the high expression rate was 59.22％(61/103).The positive rate and the high expression rate of NQO1 in HBV-HCC tissues were higher than those in adjacent normal tissues(P＜0.05).There were statistically significant differences in tumor maximum diameter,number of lesions,American Joint Committee on Cancer(AJCC)staging,and vascular invasion between patients with high and low expression of NQO1(P＜0.05).The 3-year follow-up results denoted that the median survival time of patients was 37 months,and no cases were lost in follow-up.Among 103 patients,there were 34 dead cases with an overall survival rate of 66.99％(69/103)and 42 recurrence cases with a recurrence-free survival rate of 59.23％(61/103).Kaplan-Meier survival curve re-sults showed that the overall survival rate and recurrence-free survival rate were 52.46％(32/61)and 50.82％(31/61)in NQO1 high expression group,which were lower than 88.10％(37/42)and 71.43％(30/42)in NQO1 low expression group(P＜0.05).COX model analysis results showed that high expression of NQO1,tumor maximum diameter ≥5 cm,multiple lesions,AJCC stage Ⅲ to Ⅳ and vascular invasion were independ-ent risk factors for prognosis(P＜0.05).Conclusion NQO1 is highly expressed in HBV-HCC tissue,and is related to the clinicopathological characteristics of patients,so it could be used as an independent biomarker for evaluating prognosis.

ABSTRACT
Acute kidney injury(AKI)is a global public health problem with high morbidity,high mortality and costly treatment cost.The pathogenesis of AKI is very complex,and the treatment strategies for AKI are lim-ited,then it is very matter to explore the pathophysiological mechanism and potential therapeutic targets of acute kidney injury.N6-methyladenosine(m6A)is the most abundant and extremely conservative epigenetic modification in eukaryotic,which is a dynamic and reversible process involving in splicing,nuclear export,translation,stabil-ity,and higher structure of RNA,and regulated by three regulatory factors:methyltransferase,demethylase and methylated reading protein.Current studies have found that m6A plays an important regulatory role in AKI and can be a potential therapeutic target for AKI.In this review,we provide a brief description of m6A and summarize the impact of m6A on AKI and possible future study directions for this research.
ABSTRACT
BACKGROUND:Immunotherapy enhances the anti-cancer immune response in many ways,so combined immunotherapy is a better choice.Ultrasound-targeted microbubble destruction technique delivers drugs,genes,antibodies and cytokines directly to the cytoplasm of immune cells and enhances the immune response.However,the application of ultrasound-targeted microbubble destruction technique in the treatment of ovarian cancer with both CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody has not been reported. OBJECTIVE:To investigate the effect of ultrasound irradiation on the proliferation and migration of ovarian cancer cells with CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody double targeted nanobubbles. METHODS:IOSE-80 normal ovarian epithelial cells,SKOV3 and CAOV3 ovarian cancer cells were cultured and expanded.Double labeling fluorescence immunoassay was used to co-locate CXC chemokine receptor 4 and programmed death-ligand 1 protein.Western blot assay was used to detect the relative expression of CXC chemokine receptor 4 and programmed death-ligand 1 protein in three kinds of cells and screen out the experimental cells,i.e.,pure nanobubbles,nanobubbles carrying CXC chemokine receptor 4 antibody,nanobubbles carrying CXC chemokine receptor 4 and programmed death-ligand 1 antibody.SKOV3 ovarian cancer cells in the logarithmic growth phase were taken and divided into six groups for treatment.Group A was added with McCoy's 5A medium.Group B was added with McCoy's 5A medium containing stromal cell-derived factor-1.Group C was added with pure nanobubble solution and McCoy's 5A medium containing stromal cell-derived factor-1.Group D was added with nanobubble solution containing CXC chemokine receptor 4 antibody and McCoy's 5A medium containing stromal cell-derived factor-1.Group E was added with nanobubble solution containing CXC chemokine receptor 4 and programmed death-ligand 1 antibody and McCoy's 5A medium containing stromal cell-derived factor-1.Pure nanobubble solution was added in group F.After ultrasonic irradiation for 120 seconds and incubation for 48 hours,the survival rate of cells was measured by CCK-8 assay,and the healing and migration ability of cells in groups B-E were measured by wound healing test. RESULTS AND CONCLUSION:(1)Immunofluorescence staining showed that CXC chemokine receptor 4 and programmed death-ligand 1 protein could be expressed in all three kinds of cells.Western blot assay showed that the expression levels of CXC chemokine receptor 4 and programmed death-ligand 1 in SKOV3 and CAOV3 ovarian cancer cells were significantly higher than those in IOSE-80 normal ovarian epithelial cells(P<0.05).(2)CCK-8 assay results exhibited that the cell survival rate of group B was higher than that of group A(P<0.05).The cell survival rate of group F was lower than that of group A(P<0.05).The cell survival rate of groups B-E decreased gradually,and there were significant differences between the two groups(P<0.05).(3)Wound healing test demonstrated that the cell healing rate of groups B-E decreased gradually,and there were significant differences between the two groups(P<0.05).(4)The results show that the use of CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody double targeted nanobubbles under ultrasound-targeted microbubble destruction can significantly inhibit the proliferation and migration of ovarian cancer cells.

observation group at T2 and T3 were significantly lower than those in the control group(P＜0.05);there were no significant differences in Ppeak and TV between the two groups at T1 and T4(P＞0.05).RR and partial pressure of end-tidal carbon dioxide(PetCO2)at T1-T4 showed no significant differences between the two groups(P＞0.05).The pH values at T0-T5 showed no significant differences between the two groups(all P＞0.05).The OI at T,had no significant difference compared to that at T0 in both groups(P＞0.05);OI at T2-T5 in both groups was significantly lower than that at T0(P＜0.05);OI in the observation group at T2-T5 was significantly higher than that in the control group(P＜0.05).Qs/Qt at T2-T5 was significantly higher than that at T0 and T1 in both groups(all P＜0.05);Qs/Qt in the observation group at T2-T5 was significantly lower than that in the control group(P＜0.05).At T3 and T5,serum SP-A and IL-6 levels in both groups were significantly higher than those at T0(P＜0.05);serum SP-A and IL-6 levels in the observation group at T3 and T5 were significantly lower than those in the control group(P＜0.05).At T3 and T5,serum IL-10 level in the control group were significantly lower than that at T0,while serum IL-10 level in the observation group were significantly higher than that at T0(P＜0.05).Serum IL-10 level in the observation group at T3 and T5 were higher than that in the control group(P＜0.05).At T3 and T5,serum MDA level in the control group was significantly higher than that at T0(P＜0.05);serum MDA level in the observation group showed no significant difference compared to that at T0(P＞0.05);serum MDA level in the observation group was significantly lower than that in the control group(P＜0.05).At T3 and T5,serum SOD level in the control group was significantly lower than that at T0,while serum SOD level in the observation group was significantly higher than that at T0(P＜0.05);serum SOD level in the observation group was significantly higher than that in the control group(P＜0.05).Four patients in the observation group experienced symptoms of unilateral recurrent laryngeal nerve block,and one patient experienced brachial plexus nerve block,but all improved within 24 hours after surgery.No other adverse reactions were observed during follow-up.Within 72 hours postoperatively,one patient in the control group experienced hypoxemia.Conclusion Preoperative ultrasound-guided SGB has lung-protective effects on patients undergoing OLV in thoracoscopic surgery,which significantly improves OI,reduces intrapulmonary shunts,and inhibits inflammatory response and oxidative stress.
ABSTRACT
OBJECTIVE To establish the project approval evaluation system for traditional Chinese medicine （TCM） preparations in medical institutions guided by new drug conversion， to improve the success rate of approval for TCM preparations in medical institutions and lay the foundation for the later drug conversion. METHODS Research and development team used the literature research method and brainstorming method to list and organize relevant elements of project evaluation and determine the initial indicator system. Experts were consulted using the Delphi method to confirm the evaluation index. The weights were calculated based on the proportion of importance scores for each indicator and assigned specific scores to each item. The indicator system was used to evaluate 31 TCM preparations applied for filing by various departments of our hospital from April to July 2023. RESULTS After two rounds of 17 experts’ consultation， the final TCM preparation system included five primary indicators， i.e. theoretical basis， clinical research foundation， pharmaceutical foundation， prescription， and clinical value， as well as 17 secondary indicators including prescription source， traditional Chinese medicine theory， clinical positioning and so on. Human experience was considered as the item which would be rejected as one vote. Based on the above indicator system， our hospital further improved the filing and project approval process for TCM preparations in medical institutions. Among the 31 TCM preparations applied for filing by various departments from April to July 2023， 8 TCM preparations with a score ≥65 were selected for development. CONCLUSIONS The evaluation system is objective， comprehensive， and highly operable. It is suitable for the selection of TCM preparations in medical institutions before research and development.

ABSTRACT
Cardiovascular diseases are preventable and controllable, and the disease burden caused by them can be reduced after preventive intervention. Attentions should be paid to the prevention of disease causes. For high-risk population, it is necessary to conduct early screening of cardiovascular diseases, control risk factors, reduce exposure level, prevent and control the occurrence or progression of diseases. Clinical prevention services are to evaluate risk factors of health in clinical sites, which can prevent diseases by personalized intervention measures. Clinical prevention services for high-risk population with cardiovascular diseases are generally at a low level in China. This article reviews the early screening, risk factors and clinical prevention services for high-risk population with cardiovascular diseases.
ABSTRACT
Deucravacitinib is a selective tyrosine kinase 2 inhibitor. It has shown certain therapeutic potential for various immune system diseases， and its use in systemic lupus erythematosus （SLE） is currently in the clinical trial stage. Deucavacitinib is easily absorbed by oral administration and can cause pharmacological effects within 24 hours. Compared with placebo， after 32 weeks of treatment， patients in the deucravacitinib group who meet the SLE response index 4 have a higher proportion， and a higher response rate in the British Isles Lupus Assessment Group’s comprehensive lupus assessment， cutaneous lupus erythematosus disease area and severity index of 50， low disease activity status， and activity， swelling， and tenderness joint counts. In terms of safety， the incidence of adverse events such as rash and acne is higher in the deucravacitinib group than placebo group， but further observation was still needed. At present， more studies are evaluating the cost-effectiveness and safety of deucravatinib in the treatment of SLE， with the expectation of more data validation of deucravatinib’s therapeutic potential.
ABSTRACT
With the accelerated aging society in China, the incidence of biliary surgical diseases in the elderly has increased significantly. The clinical characteristics of these patients indicate that improving treatment outcomes and realizing healthy aging are worthy of attention. How to effectively improve the treatment effect of geriatric biliary surgical diseases has attracted widespread attention. This paper reviews and comments on the hotspots and difficulties of biliary surgery in older patients from six aspects: (1) higher morbidity associated with an aging society, (2) prevention and control of pre-operative risks, (3) extending the indications of laparoscopic surgery, (4) urgent standardization of minimally invasive surgery, (5) precise technological progress in hepatobiliary surgery, and (6) guarantee of peri-operative safety. It is of great significance to fully understand the focus of controversy, actively make use of its favorable factors, and effectively avoid its unfavorable factors, for further improving the therapeutic effects of geriatric biliary surgical diseases, and thus benefits the vast older patients with biliary surgical diseases. Accordingly, a historical record with the highest age of 93 years for laparoscopic transcystic common bile duct exploration has been created by us recently.

Chemicals possessing reactive electrophiles can denature innate proteins leading to undesired toxicity, and the overdose-induced liver injury by drugs containing electrophiles has been one of the major causes of non-approval and withdraw by the US Food and Drug Administration (FDA). Elucidating the associated proteins could guide the future development of therapeutics to circumvent these drugs' toxicities, but was largely limited by the current probing tools due to the steric hindrance of chemical tags including the common "click chemistry" labels. Taking the widely used non-steroidal anti-inflammatory drug acetaminophen (APAP) as an example, we hereby designed and synthesized an APAP analogue using fluorine as a steric-free label. Cell toxicity studies indicated our analogue has similar activity to the parent drug. This analogue was applied to the mouse hepatocellular proteome together with the corresponding desthiobiotin-SH probe for subsequent fluorine-thiol displacement reactions (FTDRs). This set of probes has enabled the labeling and pull-down of hepatocellular target proteins of the APAP metabolite as validated by Western blotting. Our preliminary validation results supported the interaction of APAP with the thioredoxin protein, which is an important redox protein for normal liver function. These results demonstrated that our probes confer minimal steric perturbation and mimic the compounds of interest, allowing for global profiling of interacting proteins. The fluorine-thiol displacement probing system could emerge as a powerful tool to enable the investigation of drug-protein interactions in complex biological environments.
ABSTRACT
ObjectiveTo determine the influence of COVID-19 prevention and control on the epidemic characteristics and dynamics of notifiable infectious diseases in the first quarters， Zhejiang Province， and to explore more effective countermeasures against infectious diseases. MethodsDescriptive epidemiology was conducted to determine the change in notifiable infectious diseases during the prevention and control of COVID-19 in Zhejiang Province by retrieving the data of notifiable infectious diseases from 2017 to 2022 in the Chinese information system for disease control and prevention. Cumulative reported new cases of notifiable infectious diseases in the first quarters of 2017‒2019 were compared with that of 2020‒2022. ResultsA total of 546 753 cases of notifiable infectious diseases were newly reported in the first quarters of 2017‒2019， with an average incidence of 321.92/105. In contrast， a total of 509 908 cases of notifiable infectious diseases were newly reported in the first quarters of 2020‒2022， during which the COVID-19 epidemic occurred， with an average incidence of 270.39/105. The incidence in 2020‒2022 significantly declined by 51.53/105， compared with that in 2017‒2019 （χ²=8 072.06， P<0.001）. In the first quarters of 2020‒2022， the average incidence of zoonotic diseases and vector-borne diseases decreased by more than 50%. In addition， the incidence of respiratory， enteric， blood-borne， and sexually transmitted diseases declined to certain degree. ConclusionThe decline in the newly reported cases of non-COVID-19 notifiable infectious diseases in the first quarters of 2020‒2022 indicates that the countermeasures against COVID-19 epidemic， such as multi-disease co-prevention， multi-sectoral collaboration， societal mobilization and personal hygiene and protection， may also decrease the incidence of multiple infectious diseases. It suggests the countermeasures are effective， which would provide evidence for routine prevention and control of infectious diseases in future.
ABSTRACT
AIM:To investigate the changes in the macular microvasculature in eyes with central retinal artery occlusion(CRAO)and paracentral acute middle maculopathy(PAMM).METHODS: Retrospective study. A total of 27 cases(27 eyes)who diagnosed with CRAO-PAMM and 29 patients(29 eyes)diagnosed as CRAO but with no PAMM were hospitalized in our hospital from January 2020 to December 2021. There were 33 normal people(33 eyes)who underwent physical examination in our hospital selected as control group. Optical coherence tomography angiography(OCTA)was used to measure retinal blood flow and thickness parameters in the 3 mm×3 mm area of the macula. The correlation among macular retinal blood flow density, retinal thickness, foveal avascular zone(FAZ)area, FAZ perimeter, acircularity index(AI), flow density in a 300-μm-wide region around the FAZ(FD-300)and lesion area, best corrected visual acuity(BCVA)in the CRAO-PAMM group was analyzed.RESULTS: Among the three groups, there were significant differences in the overall and parafoveal blood flow density of superficial capillary layer(SCP)and deep capillary layer(DCP), foveal thickness, FAZ area, FAZ perimeter, AI and FD-300(all P<0.05). In the CRAO-PAMM group, the lesion area was negatively correlated with DCP overall and parafoveal blood flow density(r=-0.569, P=0.002; r=-0.543, P=0.004), and positively correlated with the parafoveal thickness(r=0.606, P=0.001); BCVA(LogMAR)was negatively correlated with DCP foveal and parafoveal blood flow density(r=-0.433, P=0.024; r=-0.515, P=0.006), and positively correlated with FAZ area, perimeter and lesion area(r=0.484, P=0.011; r=0.531, P=0.004; r=0.417, P=0.030).CONCLUSION:Patients with CRAO and PAMM have lower macular blood flow density, heavier macular edema and poorer visual acuity, and BCVA may be influenced by both lesion area and FAZ area.
ABSTRACT
Objective:To investigate the effect of ultrasound-guided stellate ganglion block (SGB) on cerebral oxygen metabolism and serum S100B protein during carotid endarterectomy (CEA).Methods:Patients aged 40-75 years old, classified as Grade Ⅱ-Ⅲ by the American Society of Anesthesiologists (ASA), and underwent elective CEA under general anesthesia at the Affiliated Suzhou Hospital of Nanjing Medical University from June 2021 to April 2023 were prospectively enrolled. They were randomly divided into an SGB group and a control group. Before anesthesia induction, the SGB group underwent ipsilateral SGB under the ultrasound guidance, while the control group did not undergo SGB. The right subclavian vein catheterization was performed under the ultrasound guidance during the general anesthesia. The mean arterial pressure (MAP) and heart rate (HR) were recorded before induction of general anesthesia (T0), during tracheal intubation (T1), before vascular occlusion (T2), after vascular opening (T3), and at the end of surgery (T4), as well as the pressure of the jugular vein bulb at each time point from T1 to T4. Arterial blood and jugular venous bulb blood were collected at various time points for blood gas analysis. Jugular venous bulb oxygen saturation (SjvO 2), arteriovenous oxygen content difference (AVDO 2), cerebral oxygen extraction rate (COER), lactate production rate (LPR) and lactate oxygen index (LOI) were calculated. The serum S100B concentration in the jugular vein bulb blood at various time points was detected with enzyme-linked immunosorbent assay. The incidence of postoperative hoarseness, hematoma, dizziness, diaphragmatic nerve block, nausea, and vomiting were recorded. Results:A total of 82 patients conducted CEA were included, with 41 patients in the SGB group and 41 in the control group. During anesthesia induction and surgery in the SGB group, HR was significantly lower than that in the control group, and the MAP and HR during tracheal intubation and at the beginning of surgery were also more stable than those in the control group (all P<0.05). In the SGB group, the changes in SjvO 2, AVDO 2, and COER were relatively smaller from T1 to T3, while SjvO 2 increased, and AVDO 2 and CEOR decreased at T4. In contrast, the control group showed a decrease in SjvO 2, AVDO 2, and COER at T3 and a slight increase at T4. At all time points, SjvO 2 in the SGB group was significantly higher than that in the control group ( P<0.05). AVDO 2 and COER in both groups gradually decreased over time, and the control group was significantly higher than the SGB group at all time points (all P<0.05). LPR and LOI increased at T1 to T4 in both groups, reaching their highest value at T3 and decreasing at T4. There was statistically significant difference at T4 and at T2 in the control group (all P<0.05). The LPR and LOI of the control group were significantly higher than those of the SGB group at all time points (all P<0.05). In addition, the serum S100B levels in both groups increased first and then decreased, but the T2-T4 levels in the SGB group were significantly lower than those in the control group at all time points (all P<0.05). The incidence of perioperative adverse events in the SGB group was significantly lower than that in the control group ( P<0.05). Conclusion:Performing ipsilateral SGB before CEA surgery can effectively inhibit stress response, maintain intraoperative hemodynamic stability, improve brain tissue oxygen supply, and have a certain neuroprotective effect.
ABSTRACT
Objective:Central nervous system leukemia(CNSL)is one of the main causes of recurrence and death in patients with acute leukemia.This study aims to dynamically monitor minimal residual disease(MRD)in cerebrospinal fluid and bone marrow of patients with different types of acute leukemia by flow cytometry(FCM),and to compare the timeliness and consistency of MRD detection between the 2 methods to further explore the application value of monitoring MRD in cerebrospinal fluid. Methods:A total of 199 patients with acute leukemia admitted to the Guangdong Provincial people's Hospital between October 2018 and January 2022 were retrospectively analyzed,and multiparametric FCM method was adopted to summarize and analyze MRD in cerebrospinal fluid of patients with different types of leukemia and MRD in cerebrospinal fluid and bone marrow specimens of the same patients,and its role in assessing the prognostic value of patients was discussed. Results:Among the 199 acute leukemia cases,a total of 31 cases(15.58%)were positive MRD in the cerebrospinal fluid,of which 18 cases(58%)were detected earlier than the corresponding bone marrow specimens.Among the 19 patients with acute T lymphoblastic leukemia,134 patients with acute B lymphoblastic leukemia,and 46 patients with acute myeloid leukemia counted,there were 4,18,and 9 patients with positive MRD in the cerebrospinal fluid.The Kappa value of the concordance test between the results of cerebrospinal fluid MRD and bone marrow MRD in different types of acute leukemia was only 0.156,demonstrating a low concordance between them. Conclusion:Dynamic monitoring of cerebrospinal fluid MRD by FCM can be used as a monitoring index for central nervous system leukemia,and monitoring cerebrospinal fluid can detect MRD earlier compared with bone marrow,which complements each other as a sensitive index for evaluating prognosis with significant guidance in clinic.
ABSTRACT
Objective To comprehensively assess the strengths and weaknesses of the 24 antihypertensive drugs procured as Volume-based Procurement(VBP)and innovator drugs by using quantitative evaluation system,and to provide a reference for doctors and patients in medication guidance and pharmaceutical decision-making.Methods The Quantitative Evaluation Criteria in the"Quick Guide to Drug Evaluation and Selection in Chinese Medical Institutions"were refined and optimized.The 24 selected VBP and innovator antihypertensive drugs were quantitatively evaluated according to the optimized quantitative evaluation system with the help of Chinese and English databases such as China Knowledge Network,Wanfang data,Wipunet,Embased,PubMed,and Metstr,as well as guideline search tools such as Meikang MCDEX,Drugwise Data,Up To Date,Medical Pulse and other databases etc.Results Among the 24 antihypertensive drugs,only four innovator drug evaluation scores were higher than those of drugs selected as VBP,namely felodipine tablets,Fosinopril sodium tablets,indapamide extended-release capsules,Irbesartan hydrochlorothiazide tablets.there were five main differences in the evaluation scores,namely economy,consistency evaluation,drug expiry date,global use,and the status of manufacturing enterprises.It was found that 83%of the VBP drugs had higher evaluation scores than those of the innovator drugs.The economic score of the innovator drug was low,and the difference in the scores was between 1-11 points.Conclusion By using the quantitative evaluation system to evaluate the antihypertensive drugs,the advantages and disadvantages of the innovator and VBP antihypertensive drugs can be assessed comprehensively,and the digital characteristics of antihypertensive drugs can be given,and the evaluation score can provide the reference basis for the guidance and decision-making of medication for doctors and patients.
