ObjectiveTo evaluate the effect of antihypertensive and lipid-regulating Chinese patent medicine combined with conventional Western medicine in the treatment of hypertension with dyslipidemia. To carry out the evidence synthesis of clinical research and provide evidence-based evidence support for clinical decision-making. MethodThe databases including China National Knowledge Infrastructure （CNKI），Wanfang Data Knowledge Service Platform （WF），VIP，SinoMed，Embase，PubMed，Web of Science （WOS），and the Cochrane Library were searched for randomized controlled trials （RCT） of all listed Chinese patent medicines in the treatment of hypertension with dyslipidemia from the establishment of the databases to April 15，2023. The literature was screened and extracted，and the risk of bias tool 2.0 （RoB2） was used to assess the quality and risk of bias of the methodology. Revman 5.4.1 software was used to analyze the outcome indicators. Grading of Recommendations Assessment，Development and Evaluation （GRADE） was applied to assess the quality of evidence formed by clinical research data. The inclusion and recommendation of Chinese patent medicines in the National Drug Catalogue for Basic Medical Insurance，Work-related Injury Insurance and Maternity Insurance （2022） and domestic guidelines and consensus were searched to form a bubble chart. ResultA total of 15 studies were included. The evaluation of the methodological quality of each study showed that the risk of bias stemmed from the lack of blinding and allocation concealment，and low sample size. The comprehensive analysis of clinical studies showed that Dengzhan Shengmai capsules combined with rosuvastatin and amlodipine besylate，Yindan Xinnaotong capsules combined with simvastatin and levamlodipine tablets，Xiaoshuan Tongluo capsules combined with nifedipine controlled release tablets and pravastatin sodium tablets，Xinshubao capsules combined with atorvastatin calcium tablets and irbesartan，Wenyading capsules combined with enalapril，and Jiangzhining tablets combined with conventional Western medicines were all superior to conventional Western medicines used in the control group in improving systolic blood pressure （SBP），diastolic blood pressure （DBP），cholesterol （TC），triglyceride （TG），low density lipoprotein cholesterol （LDL-C），and high density lipoprotein cholesterol （HDL-C）. There was no significant difference in the incidence of adverse reactions between the two groups. The GRADE evaluation of the main outcome indicators showed that the evidence quality of SBP and incidence of adverse reactions was graded as B，that of DBP as C，and that of total TC，TG，LDL-C，and HDL-C as D. The evaluation of Chinese patent medicines covered by medical insurance and recommended by guidelines and consensus showed that Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules belonged to class B drugs of medical insurance，and were recommended for 7，6 and 3 times in the guidelines and consensus，respectively. ConclusionCompared with simple medicine treatment，Chinese patent medicine combined with conventional Western medicine has more advantages in improving blood pressure and blood lipid，and shows higher safety. Among them，Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules have stronger clinical applicability and economy. All the trials included in this article adhered to the principle of randomization and reported the outcome measures. However，the quality of evidence in related clinical studies was low. In terms of trial design，large-sample，multi-center，blinded randomized controlled trials based on the consolidated standards of reporting trials （CONSORT） statement are still needed for comprehensive trial designs and reporting，to further improve the GRADE quality evaluation and guideline formulation under the guidance of evidence-based medicine，so as to provide higher quality evidence-based research evidence for clinical decision-making.

ObjectiveTo evaluate the quality of research and evidence related to antihypertensive Chinese patent medicines combined with western medicines for the treatment of hypertension， synthesize and update the evidence， form expert consensus， and provide evidence for clinical decision-making. MethodThe databases of China National Knowledge Infrastructure （CNKI）， WanFang Data Knowledge Service Platform （WanFang）， Vip Chinese Science and Technology Journal Database （VIP）， Chinese Biomedical Literature Service System （Sinomed）， National Library of Medicine （PubMed）， Cochrane Library， Web of Science， and US Clinical Trials Registry were searched for randomized controlled trials of antihypertensive Chinese medicine combined with western medicine for the treatment of hypertension from database construction to July 31， 2022. The quality of the literature was evaluated using the bias risk assessment tool in Cochrane Handbook 6.3. Evidence synthesis of main outcome indicators was performed using R software. The Grading of Recommendations Assessment， Development， and Evaluation profiler （GRADEprofiler） 3.6 was employed to evaluate the quality of evidence. Expert consensus was formed based on the Delphi method after two rounds of voting. Result64 pieces of literature were included， and the results of literature quality evaluation and risk of bias showed that 70.31% （45/64） of the studies indicated some risks， and 29.69% （19/64） indicated high risks. Compared with conventional western medicines， the combination of Chinese patent medicines with western medicines can significantly lower systolic pressure （SBP） and diastolic pressure （DBP）， increase the effective rate of antihypertensive， reduce the incidence of adverse reactions， endothelin-1， and traditional Chinese medicine syndrome scores. Egger's test showed that Songling Xuemaikang capsules reduced SBP and DBP. Tianma Gouteng granules reduced SBP and DBP and increased the effective rate of antihypertensive， and Xinmaitong capsules reduced SBP and increased the effective rate of antihypertensive， without significant publication bias. Songling Xuemaikang capsules increased the effective rate of antihypertensive， and Xinmaitong capsules decreased DBP， with significant publication bias. The results of the GRADE evidence quality evaluation showed that most evidence was at grades B and C. Finally， four strong recommendations and 14 weak recommendations were formed. ConclusionCompared with conventional western medicines for the treatment of hypertension， antihypertensive Chinese patent medicines combined with western medicines have advantages in reducing blood pressure and improving drug use safety， but they are mostly weak recommendations in terms of efficacy， and more high-quality evidence is needed.

ObjectiveTo systematically collect， analyze， and evaluate the randomized controlled trials （RCT） of Chinese patent medicine combined with western medicine in the treatment of hypertension， map the evidence， and provide reference for the future clinical research and formulation of guidelines and policies. MethodThe relevant articles were retrieved from China Biology Medicine disc， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， PubMed， Embase， and Cochrane Library with the time interval from inception to December 31， 2022. The RCT of Chinese patent medicines combined with western medicine in the treatment of hypertension were included. The research characteristics and methodological quality were analyzed and evaluated. ResultA total of 330 RCTs of treating hypertension with Chinese patent medicines combined with Western medicine were included in this study， all of which were published in Chinese. These RCTs involved 88 Chinese patent medicines and 37 788 patients， and 46% of RCT had the sample size ≥100 patients. Eighty-seven percent of RCT showed the study period within 3 months. All the interventions in the RCTs were Chinese patent medicine + western medicine vs western medicine. Among the evaluation indicators， blood pressure， response rate， TCM syndrome score， endothelial cell function， and safety were mainly concerned. In terms of methodological quality， most articles did not mention the generation of random sequences， allocation concealment， or blinding method. The blinding evaluation of outcomes showed low risks of bias， and there was insufficient information to judge whether there was selective bias or other bias. ConclusionThere were many Chinese patent medicines used in combination with western medicine in the treatment of hypertension， and they were mainly taken orally. The existing RCT had problems such as small sample size， unclear clinical value positioning， imperfect design failing to reflect the value of Chinese patent medicines， unreasonable measurement indicators， and non-standard measurement methods. Future research should solve the above problems， improve the research quality， value， and authenticity， and enhance the reliability and extension of evidence.

Objective To establish an early prediction model for the diagnosis of severe acute pancreatitis based on the improved machine learning models,and to analyze its clinical value.Methods A case-control study was conducted on 352 patients with acute pancreatitis admitted to the Gastroenterology and Hepatobiliary Surgery Departments of the Army Medical Center of PLA and Emergency and Critical Care Medicine Department of No.945 Hospital of Joint Logistics Support Force of PLA from January 2014 to August 2023.According to the severity of the disease,the patients were divided into the severe group(n=88)and the non-severe group(n=264).The RUSBoost model and improved Archimead optimization algorithm was used to analyze 39 routine laboratory biochemical indicators within 48 h after admission to construct an early diagnosis and prediction model for severe acute pancreatitis.The task of feature screening and hyperparameter optimization was completed simultaneously.The ReliefF algorithm feature importance rank and multivariate logistic analysis were used to analyze the value of the selected features.Results In the training set,the area under curve(AUC)of the improved machine learning model was 0.922.In the testing set,the AUC of the improved machine learning model reached 0.888.The 4 key features of predicting severe acute pancreatitis based on the improved Archimedes optimization algorithm were C-reactive protein,blood chlorine,blood magnesium and fibrinogen level,which were consistent with the results of ReliefF algorithm feature importance ranking and multivariate logistic analysis.Conclusion The application of improved machine learning model analyzing the laboratory examination results can help to early predict the occurrence of severe acute pancreatitis.

Objective To investigate the serum levels of microRNA-892b(miR-892b)and growth-associat-ed oncogene product β(GROβ)in patients with gastric cancer and their clinical significance.Methods A total of 124 patients with gastric cancer admitted to the hospital from February 2019 to February 2022 were select-ed as the gastric cancer group,and 100 volunteers with normal gastroscopy were selected as the control group during the same period.Serum levels of miR-892b and GROβ were detected in the two groups,and the rela-tionship between serum levels of miR-892b and GROβ and clinicopathological characteristics of patients with gastric cancer was analyzed.Multivariate Cox regression analysis was used to explore the influencing factors of prognosis of patients with gastric cancer.Results The serum level of miR-892b in gastric cancer group was lower than that in control group,and the serum level of GROβ was higher than that in control group(P＜0.05).There were statistically significant differences in serum miR-892b and GROβ levels in gastric cancer pa-tients with different degrees of differentiation,maximum tumor diameter lymph node metastasisand TNM stage(P＜0.05).A total of 124 patients with gastric cancer were followed up for one year after discharge,91 patients survived,and the overall survival rate was 73.39％.The one year overall survival rate of gastric cancer patients was related to the degree of differentiation,maximum tumor diameter,lymph node metastasis and TNM stage(P＜0.05).The overall survival rate of gastric cancer patients with high expression of serum miR-892b and low expression of GROβ was higher than that of patients with low expression of serum miR-892b and high expression of GROβ(P＜0.05).Multivariate Cox regression analysis showed poor differentia-tion(HR=1.839,95％CI 1.048-3.227),lymph node metastasis(HR=1.791,95％CI 1.076-2.982),TNM stage Ⅲ-Ⅳ(HR=1.660,95％CI 1.015-2.715),low expression of serum miR-892b(HR=3.040,95％CI 1.592-5.805),high expression of serum GROβ(HR=2.277,95％CI 1.503-3.451)were risk fac-tors for the prognosis of gastric cancer patients(P＜0.05).Conclusion The serum level of miR-892b is de-creased and the level of GROβ is increased in patients with gastric cancer,which is closely related to the occur-rence and development of gastric cancer.The expression of miR-892b and GROβ is related to the clinicopatho-logical characteristics and prognosis of patients,and can be used as a biological indicator to evaluate the prog-nosis of patients with gastric cancer.

Objective:To explore the mechanism of acupuncture combined with sand therapy on bone biomechanics and immune function in rabbits with knee osteoarthritis based on G protein coupled signal.Methods:Totally 35 rabbits were randomly divided into normal group, model group, sand therapy group, acupuncture and moxibustion group and combined group, with 7 rabbits in each group. Except for the normal group, all other groups were prepared with knee osteoarthritis models. After 12 h modeling, rabbits in the sand therapy group and the combined group were treated with sand therapy. Rabbits in the acupuncture and moxibustion group and the combined group received acupuncture stimulation intervention therapy. Rabbits in normal group and model group only moved freely. The levels of IgG, IgM and IgA in serum and IL-1β and TNF-α were detected by ELISA method. The biomechanical properties of femur were measured by American Instron universal material experimental machine. The pathological changes of rabbits in each group were observed by HE staining. Protein expression levels of Gαs, cAMP and Gi in rabbit cartilage tissues were detected by Western blot.Results:Compared with model group, the levels of IgG, IgM and IgA increased ( P<0.05)l the levels of IL-1β and TNF-α decreased ( P<0.05); the maximum load, breaking load, structural stiffness and capacity absorption of rabbits in sand therapy group, acupuncture group and combined group increased ( P<0.05); the expressions of Gαs and cAMP protein increased ( P<0.05), while the expression of Gi protein decreased ( P<0.05). Conclusion:Acupuncture combined with sand therapy in the treatment of knee osteoarthritis can effectively improve the bone strength of osteoarthritis, reduce the inflammatory response, balance the expression of G protein and improve the imbalance of immunoglobulin.

Objective:To investigate the effects of external application of Compound Dahuang Powder combined with acupuncture on the synovial ultrastructure, pathological angiogenesis, and Ras/Raf signaling pathway in rheumatoid arthritis rats.Methods:Totally 100 SPF grade SD rats were selected and divided into normal group, model group, acupuncture group, external application group, and combination group according to random number table method, with 20 rats in each group. Except for the normal group, Freund's complete adjuvant was injected into the bilateral plantars to establish a rheumatoid arthritis model. One week after modeling, the acupuncture group received acupuncture at "Yinlingquan (SP9)" and "Sanyinjiao (SP6)" for 30 minutes, with continuous intervention for 6 days and 7 days as one course of treatment, for a total of 3 courses of intervention. The external application group of rats applied compound Dahuang Powder on the right hind foot and ankle joint, 10 g/time, twice a day, for 7 days as one course of treatment, with a total of 3 intervention courses; the combination group received a combined intervention of acupuncture and external application of compound Dahuang Powder. No intervention was performed in the normal group and model group. The levels of TNF-α and IL-1β in serum of rats in each group were detected using enzyme-linked immunosorbent assay. Transmission electron microscopy was used to observe the ultrastructure of synovial cells. HE staining was used to observe the morphology of synovial tissue. Immunohistochemistry was used to detect vascular endothelial growth factor (VEGF) and its receptor VEGFR2 in synovial tissue. Western blot and RT qPCR were used to detect Ras/Raf protein and mRNA in synovial tissue, respectively.Results:Compared with model group, the levels of TNF-α and IL-1β in serum of rats in acupuncture group and external application group decreased ( P<0.05), the expressions of VEGF and VEGFR2 decreased ( P<0.05), and the expressions of Ras and Raf protein and mRNA in acupuncture group and external application group decreased ( P<0.05). Compared with acupuncture group and external application group, the levels of TNF-α and IL-1β in serum of rats in the combination group decreased ( P<0.05), the expressions of VEGF and VEGFR2 decreased ( P<0.05), and the expressions of Ras and Raf protein and mRNA in the combination group decreased ( P<0.05). The results of synovial cell ultrastructure showed that the nuclear membrane of synovial cells in normal group was good, and the nuclear membrane in model group was seriously damaged. The acupuncture group and external application group had different degrees of improvement, and the combination group had the most significant improvement. HE staining results showed that the joint synovial tissue of the normal group was normal, the joint synovial tissue of the model group had a large amount of inflammatory infiltration, the joint synovial injury of the acupuncture group and the external application group was slightly improved, and the pathological injury of the combined group was significantly reduced. Conclusion:The combination of external application of compound Dahuang Powder and acupuncture can regulate angiogenesis related factors, regulate the Ras/Raf signaling pathway, and improve the ultrastructure of synovial cells in rheumatoid arthritis model rats.

Objective To investigate the effect of progesterone receptor membrane component 1(PGRMC1)mediated autophagy on the sensitivity of liver cancer cells to 125I particles irradiation.Methods Hepatoma cell lines Huh7 and LM3 were exposed to different doses(0,2,4,6 and 8 Gy)of 125I particles,and cell autophagy was observed by transmission electron microscopy(TEM).Then,autophagy inhibitor chloroquine(CQ),agonist rapamycin(Rapa),and PGRMC1 inhibitor AG-205 were used respectively to verify that PGRMC1-mediated autophagy plays a key role in the sensitivity of hepatocellular carcinoma cells to 125I particle irradiation.Cell proliferation,colony formation and apoptosis were detected by CCK-8 assay,clonal formation test and flow cytometry,respectively.The expression levels of PGRMC1,microtubule-associated protein light chain 3-Ⅰ(LC3-Ⅰ),LC3-Ⅱ and p62 were detected by Western blotting.Results Different doses of 125I particles irradiation significantly decreased the proliferation and clonogenesis of Huh7 and LM3 cells(P＜0.05),and increased the apoptotic cells(P＜0.01),in a dose-dependent manner.Compared with the 0 Gy group,the ratio of LC3-Ⅱ/LC3-Ⅰ in Huh7 and LM3 cells was obviously increased,and the expression of p62 was significantly down-regulated in the 6 Gy group.The proliferation capacity and clonal formation ability of Huh7 and LM3 cells were decreased significantly,and their apoptotic cells were increased notably in the 6 Gy+CQ group than the 6 Gy group,while the above results were on the contrary in the 6 Gy+Rapa group.The 6 Gy+AG205 group had notably decreased LC3-Ⅱ/LC3-Ⅰ ratio in the Huh7 and LM3 cells,up-regulated p62 expression,reduced cell proliferation capacity and clone formation ability,and enhanced cell apoptosis when compared with the 6 Gy group,and the above results of the 6 Gy+PGRMC1 group were opposite.Conclusion Increment of PGRMC1 induced by 125I irradiation can promote autophagy,increase the proliferation and clonogenesis,and reduce the apoptosis in hepatocellular carcinoma cells.

Objective:To analyze the Chinese thyroid imaging reporting and data system (C-TIRADS) classification combined with ultrasonic shear wave elastography (SWE) and super microvascular imaging technology (SMI) in the diagnosis of benign and malignant thyroid nodules.Methods:Clinical data of 125 patients undergoing thyroid nodule surgery in the Department of Ultrasound Medicine, Shantou Central Hospital were retrospectively analyzed. There were 35 males and 90 females. The disease duration was (3.45±1.32) years, ranging from 3 months to 7 years; the age was (55.45±3.31) years old, ranging from 25 to 70 years old; the maximum diameter of the nodule is (12.13±5.76) mm, ranging from 5.0 to 42.9 mm. C-TIRADS classification, SWE, SMI and pathological diagnosis results of ultrasonic nodules in patients were analyzed. The diagnostic performance of C-TIRADS classification, SWE, SMI and combined diagnosis of malignant nodules were analyzed. SPSS 21.0 software was used to analyze the data, and the measurement data were consistent with the normal Statistical distribution, independent t test was performed for comparison between two groups; count data were expressed as rate (%), and χ2 test was used. Results:A total of 180 lesions were detected this time. According to pathological diagnosis, there were 114 benign nodules and 66 malignant nodules; the malignant percentage of C-TIRADS 4B nodules was the highest, reaching 72.00% (36/50) ; Emix of malignant nodules, Emax and Emean were (15.98±6.56) kPa, (84.22±24.23) kPa and (63.29±15.89) kPa respectively, which were significantly higher than those of benign nodules (13.56±4.68) kPa, (48.33±14.46) kPa and (37.32±12.63kPa) ( t=2.49, 8.76, 9.07, P<0.05) ; Type IV malignancy accounted for the highest proportion in SMI classification of thyroid nodules, which was 78.95%; the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the joint diagnosis were 94.64%, 92.85%, 94.64%, 42.85%, 90.16%, higher than the single C-TIRADS classification (89.65%, 75.00%, 89.65%, 37.50%, 80.55%), SMI (82.35%, 55.56%, 89.36%, 32.60%, 78.33%), and SWE diagnosis (81.08%, 56.00%, 90.22%, 28.57%, 77.22%). The difference was statistically significant ( P<0.05) . Conclusions:Compared with the diagnostic efficiency of SWE, SMI and C-TIRADS classification alone, the combined use of the three has higher diagnostic efficiency for benign and malignant thyroid nodules. The abuse of invasive procedures can be reduced or avoided.

In order to solve the problem of strong subjectivity and difficulty in quantification,clinical objectification mainly adopts the techniques of image processing,computer vision and machine learning.The acquisition and processing of prior knowledge is a key link in the objectification of inspection,as well as an important elaboration of the quantification of subjective judgment and macro performance in objectification research.However,there is still a lack of in-depth summary and parametric processing of prior knowledge.Based on the analysis of the current research status of objectification of inspection,this paper uses data mining technology to summarize the experience of TCM inspection.Moreover,the observation information can be transformed into quantifiable digital features through natural language processing and representation learning.Meanwhile,the application of deep learning can realize automatic diagnosis and analysis of observation images to improve accuracy and efficiency,and promote the process of TCM modernization.
