OBJECTIVE Metastasis-associated in colon cancer-1 (MACC1) is an oncogene that has been newly identified. It promotes tumor proliferation and invasion via the MET pathway. Our study investigated the effects of Saikosaponin-b(SS-b) on the proliferation and apoptosis of HepG2 cells and its regulation on MACC1/c-Met/Akt signaling pathway. METHODS HepG2 cells were treated with SS-b (10-800 g·L-1) for 48 h in vitro. The CCK-8 assay was used to assess cell proliferation, and cell apoptosis was determined by Hoechst33258 staining, AnnexinⅤ/PI staining and caspase 3 assay. RT-PCR was used to examine the expression of MACC1, c- MET and hepatocyte growth factor (HGF) mRNA. MACC1 protein was detected by Western blot and immunohistochemistry. The protein expressions of p-c-MET, c-MET, p-AKT, AKT, p-BAD, BAD were measured by Western blot. RESULTS SS-b inhibited the growth of HepG2 cells in dose-dependent way and induced cell apoptosis significantly. HepG2 cells showed karyopyknosis, fragmentation and fluorescence highlight in SS-b treatment group. FCM results showed that apoptosis rate of HepG2 cells increased with SS- b concentration. The immunofluores?cence results showed that the MACC1 expression decreased significantly in HepG2 cells treated with SS-b. The expression levels of MACC1, c-MET and HGF mRNA in HepG2 cells were significantly inhibited by SS-b. SS-b also significantly decreased the protein expressions of MACC1, p-c-MET and p-AKT while increased the expression of p-BAD and caspase 3 in HepG2 cells(P<0.05). CONCLUSION SS-b inhibited the proliferation and induced the apoptosis of HepG2 cells by targeting the MACC1/c-Met/Akt signaling pathway.

External snapping hip(ESH) is a vague term used to describe palpable or auditory snapping with hip movements with or without pain. The pathogenesis of ESH is related to the specific anatomical structure and friction factor. The clinical symptom is auditory snapping during activities, physical examination, X-ray, magnetic resonance imaging(MRI), dynamic ultrasound and other imaging techniques can be used to diagnose. Conservative medical management includes rest, avoidance of aggravating activities, and antiinflammatory medications. Treatment Patients with mild symptoms can achieve good results by medication, rest and physiotherapy. Surgical treatment for patients with ineffective conservative treatment was performed. All kinds of open surgery method can achieve good clinical curative effect, arthroscopic surgery is gradually been promoted due to small trauma, less complications. Besides, there are some reports that traditional treatments such as massage, acupuncture and acupotomology have achieved good clinical results, which deserve further study and promotion.

Objective To investigate the mechanism of improvement of gait behavior in PD rat models by low frequency electrical stimulation of pedunculopontine tegmental nucleus (PPTN) by optogenetics method. Methods (1) Twenty-four healthy adult male SD rats were randomly divided into a sham-operated group 1, a lesion group 1 and a photoactivation group (n=8); normal saline was injected into the right medial frontal tract (MFB) of the sham-operated group 1; 6-hydroxydopamine (6-OHDA) was injected into the lesion group 1 and photoactivation group to induce PD models; two weeks after modeling, injection of adeno-associated virus hsynapsin-ChR2-mcherry into the right PPTN of the three groups was performed, and the photoactivation group received blue-ray stimulation by implanting optical fibers into the PPTN at the same time. (2) Twenty-four healthy adult male SD rats were randomly divided into a sham-operated group 2, a lesion group 2 and a photoinhibition group (n=8);normal saline was injected into right MFB of the sham-operated group 2; 6-OHDA was injected into the lesion group 2 and photoinhibition group to induce PD models; two weeks after modeling, injection of adeno-associated virus hsynapsin-NpHR-mcherry into the right PPTN of the three groups was performed, and the photoinhibition group received yellow-ray stimulation by implanting optical fibers into the PPTN at the same time. (3) Three weeks after injection of adeno-associated virus, Catwalk gait analysis was used to assess the behavioral ability of rats in each group. Results (1) As compared with the sham-operated group 1, lesion group 1 had significantly increased front claw spacing and back front claw spacing, and significantly decreased stride length and pressure of damaged lateral and contralateral limbs, and significantly decreased swing speed of contralateral limb (P<0.05); as compared with those in the lesion group 1, the front claw spacing and back claw spacing were significantly shortened, and stride length and pressure of damaged lateral and contralateral limbs were statistically increased in the photoactivation group (P<0.05). (2) As compared with the sham-operated group 2, lesion group 2 had significantly increased front claw spacing and back front claw spacing, significantly decreased stride length of damaged lateral limb, and significantly decreased pressure and swing speed of damaged lateral and contralateral limbs (P<0.05); no significant differences were noted on the front claw spacing and back front claw spacing, pressure and swing speed of damaged lateral and contralateral limbs between lesion group 2 and photoinhibition group (P>0.05). Conclusion The mechanism of low frequency electrical stimulation of PPTN improving gait behavior of PD rat models is related to activation of PPTN neurons.

OBJECTIVE To study the prediction effect of TCM physical personality and constitution on the risks of MD complicated with CHD.METHODS TCM physical personality and constitution of 110 T2MD patients were tested by five pat-tern personality inventor and five-five constitution.CHAID model of decision tree in EXCEL and SPSS was used to establish disease risk model of MD complicated with CHD predicted by TCM personality and constitution types.And the prediction ac-curacy of the model was evaluated.RESULTS Tested by cross validation,the prediction accuracy of MD disease model estab-lished with the Shao-yin personality,Yin-cold constitution and blood-stasis constitution as the predictor variables was relatively higher(93.6%),and three rules for predicting CHD risk were obtained.CONCLUSIONS The prediction rules of the MD complicated with CHD by TCM personality and constitution are consistent with the traditional understanding of Chinese medi-cine,which provides a reference for high-risk population's early screening,CHD prevention and treatment,clinical differentia-tion and treatment.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

OBJECTIVE: To investigate the predictive value of blood cell ratios and inflammatory markers for adverse prognosis in patients with primary Sjögren's syndrome (PSS) combined with coronavirus disease 2019 (COVID-19). METHODS: We retrospectively collected clinical data from 80 patients with PSS and COVID-19 who visited the Rheumatology and Immunology Department of the First Affiliated Hospital of Nanchang University from December 2022 to February 2023. Inclusion criteria were (1) meeting the American College of Rheumatology (ACR) classification criteria for Sjögren's syndrome; (2) confirmed diagnosis of COVID-19 by real-time reverse transcription polymerase chain reaction or antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); (3) availability of necessary clinical data; (4) age > 18 years. According to the clinical classification criteria of the "Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia (trial the 10th Revised Edition)", the patients were divided into the mild and severe groups. Disease activity in primary Sjögren' s syndrome was assessed using the European League Against Rheumatism (EULAR) Sjögren' s syndrome disease activity index (ESSDAI). Platelet-lymphocyte ratio (PLR), C-reactive protein-lymphocyte ratio (CLR), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and other laboratory data were compared between the two groups within 24-72 hours post-infection. RESULTS: The mild group consisted of 66 cases with an average age of (51. 52±13. 16) years, and the severe group consisted of 14 cases with an average age of (52.64±10.20) years. Disease activity, CRP, platelets, PLR, and CLR were significantly higher in the severe group compared with the mild group (P < 0.05). Univariate analysis using age, disease activity, CRP, platelets, PLR, and CLR as independent variables indicated that disease activity, CRP, PLR, and CLR were correlated with the severity of COVID-19 (P < 0.05). Multivariate logistic regression analysis further confirmed that PLR (OR=1.016, P < 0.05) and CLR (OR=1.504, P < 0.05) were independent risk factors for the severity of COVID-19 in the critically ill patients. Receiver operator characteristic (ROC) curve analysis showed that the area under the curve (AUC) for PLR and CLR was 0.708 (95%CI: 0.588-0.828) and 0.725 (95%CI: 0.578-0.871), respectively. The sensitivity for PLR and CLR was 0.429 and 0.803, respectively, while the highest specificity was 0.714 and 0.758, respectively. The optimal cutoff values for PLR and CLR were 166.214 and 0.870, respectively. CONCLUSION PLR and CLR, particularly the latter, may serve as simple and effective indicators for predicting the prognosis of patients with PSS and COVID-19.

The present study systematically sorted out the existing research on Qilong Capsules in the treatment of ischemic stroke with Qi deficiency and blood stasis syndrome and comprehensively evaluated its clinical evidence and value to highlight the advantages and characteristics of products and provide references for the decision-making of national pharmaceutical management departments. Based on the evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, and pharmacoeconomics, the qualitative and quantitative evaluation of "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, and accessibility, as well as characteristics of traditional Chinese medicine(TCM) was performed with multi-criteria decision analysis(MCDA) mo-del using the information, such as public data, literature data, pharmaceutical research, and questionnaire survey, and CSC v2.0 was used to calculate the clinical value of Qilong Capsules. The evaluation results were grade A, B, C, or D. Spontaneous reporting system(SRS) monitoring data, literature reports, clinical trials, and other multi-source safety evidence showed that the main adverse reactions of this drug included dry mouth, nausea, and rash, and no severe adverse reactions was found. The evidence was sufficient with small and controllable known risks, and the safety was grade A. Meta-analysis showed that Qilong Capsules combined with conventional western medicine in the treatment of acute ischemic stroke was superior to the control group in improving neurological deficits, clinical total response rate, patients' activities of daily living, and hemorheological indexes. The level of evidence was high with manifest clinical significance, and the effectiveness was grade A. The results of pharmacoeconomic research showed that Qilong Capsules combined with conventional western medicine in the treatment of ischemic stroke were advantageous in cost-effectiveness as compared with conventional western medicine alone, but the incremental effect was not significant. The quality evaluation results of the economic report were comparatively clear, and the economy was grade B. Aiming at major cerebrovascular diseases in the society and giving full play to the advantages of TCM, Qilong Capsules focused on the inheritance of classics and scientific and technological innovation, and innovation was grade B. The results of the questionnaire survey showed that the technical characteristics and drug application could meet the medication needs of clinical doctors and patients, and the suitability was grade B. The price level of this drug was comparatively high and the affordability was good since the treatment cost accounted for a small proportion of disposable income. The drug accessibility was good with a wide range of drug sales, sufficient production capacity, and sustainable medicinal materials resources, and was grade B. This drug was derived from the classic prescription Buyang Huanwu Decoction with rich experience of human application, which could regulate Qi and blood circulation, and the section of TCM characteristics was grade B. Based on the evidence evaluation results of "6+1" dimensions of Qilong Capsules, the comprehensive evaluation of clinical value was class A. It is suggested that it can be transformed into relevant policy results of basic clinical medication management according to procedures.
