OBJECTIVE To provide reference for Smilax glabra quality control. METHODS UPLC method was established to simultaneously determine the contents of 5-O-caffeoylshikimic acid， neoastilbin， astilbin， neoisoastilbin， isoastilbin， engelitin， resveratrol and isoengelitin in 20 batches of S. glabra from different areas （No. S1-S20）. The quality evaluation of 20 batches of samples was performed by chemometrics； the differential biomarkers that affected the quality of S. glabra were screened. RESULTS The measured 8 components had good linear relationship within the range of measured concentration （r≥0.999 6）. RSDs of precision， repeatability and stability tests （24 h） were all lower than 2.00% （n＝6）. The average recoveries varied between 97.60% and 106.40% （RSDs were all lower than 2.00%， n＝6）. Cluster analysis showed that the samples produced in Zhejiang （S1-S5） and Jiangxi （S6-S10） were clustered into one category； the samples produced in Hunan （S11-S15） were clustered into one category； the samples produced in Yunnan （S16-S20） were clustered into one category. Principal component analysis showed that the first two principal components could represent 85.60% information of 8 components in S. glabra. Partial least squares-discriminant analysis showed that variable importance projection values of 5-O-caffeoylshikimic acid， astilbin， isoastilbin and neoastilbin were all greater than 1. CONCLUSIONS There are differences in the contents of the above 8 components in S. glabra from different origins； 5-O-caffeoylshikimic acid， astilbin， isoastilbin and neoastilbin may be differential markers affecting the quality of S. glabra.

Objective To investigate the risk factors for recurrence of persistent atrial fibrillation(AF)after radiofrequency ablation with circumferential pulmonary vein isolation+top line+back wall line based on the features of cardiac imaging and serum biomarkers,and then to establish a nomogram risk prediction model.Methods A total of 172 patients with persistent AF admitted to our hospital from June 2022 to September 2023 were enrolled and then according to recurrence or not in 6 months after surgery,they were divided into the recurrence group(51 cases)and the non-ecurrence group(121 cases).Before surgery,routine electrocardiography,and transthoracic and esophageal echocardiography were performed,while blood routine indicators and related biochemi-cal indicators were measured.All patients underwent radiofrequency ablation with circumferential pulmonary vein isolation,top line,and back wall line.They were followed up for 6 months after surgery.Binary logistic analysis was used to analyze the independent risk factors for postoperative recurrence,and then a nomogram risk prediction model was constructed and its diagnostic per-formance was evaluated.Results Lager LAD,higher LAVI,neutrophil count and NLR,and ele-vated BNP and CRP levels,while lower LAAFV,LAAEV and LAAEF were observed in the re-current group than those in the non-recurrent group(P＜0.01).Binary logistic regression analysis showed that elevated LAVI(OR=1.160,95％CI:1.006-1.337),decreased LAAEV(OR=0.740,95％CI:0.583-0.940),decreased LAAEF(OR=0.608,95％CI:0.422-0.877),elevated BNP(OR=1.017,95％CI:1.004-1.030),and higher NLR(OR=10.116,95％CI:1.316-77.755)were independent risk factors for recurrence after radiofrequency ablation of pulmonary vein isolation+top line+posterior wall line in persistent AF patients(P＜0.05,P＜0.01).The AUC value of the nomogram model constructed with LAVI,LAAEV,LAAEF,BNP and NLR in predicting postop-erative recurrence was 0.889(95％CI:0.833-0.932).Conclusion The cardiac imaging parame-ters LAVI,LAAEV and LAAEF,and serum biomarkers BNP and NLR are closely associated with postoperative recurrence of persistent AF in patients after radiofrequency ablation with cir-cumferential pulmonary vein isolation+top line+back wall line,and the relevant nomogram mod-el has better diagnostic value for postoperative recurrence.

AIM: To explore the molecular mechanism of sequoiaflavone affecting gastric cancer cells. MEHTODS: Gastric cancer cell line AGS cells were treated with gradient concentrations of sequoiaflavone, and then induced by PI3K/AKT signaling pathway activator. The optimal inhibitory concentration and time of semi-inhibitory concentration of red cedar flavonoid on AGS cells were detected by CCK-8, and the changes of cell proliferation, migration and invasion ability were detected by colony formation assay, transwell assay and wound healing assay. PI3K/AKT signal pathway related proteins p-PI3K, PI3K, p-AKT and AKT were detected by western blot. RESULTS: Sequoiaflavone inhibited AGS cells in a concentration-dependent manner. The half inhibitory concentration was 0.5 mmol/L, the optimal treatment time was 48 h. The protein expression of p-PI3K and p-AKT was down regulated. The proliferation, migration and invasion of AGS cells were decreased after treated with sequoiaflavone. After treated with PI3K / AKT signal pathway activator, the protein expression level of pPI3K and p-AKT was partially reversed, and the ability of cell viability, proliferation, migration and invasion was also partially improved. CONCLUSION: Inactivation of PI3K/AKT signaling pathway caused by sequoiaflavone inhibited gastric cancer cells proliferation, migration and invasion ability.

Objective:To explore the value of Glasgow coma score (GCS) combined with optic nerve sheath diameter (ONSD) in predicting the death risk of patients with cerebrocardiac syndrome (CCS).Methods:From January 2021 to September 2021, 83 patients with CCS secondary to severe traumatic brain injury (sTBI) in our hospital were collected and divided into a survival group ( n = 37) and death group ( n = 46) according to CCS-related death. The clinical data including age, sex, underlying diseases, head CT imaging manifestations, electrolytes, blood glucose, C-reactive protein (CRP), neuron-specific enolase (NSE), lactate dehydrogenase (LDH), creatine kinase (CK), creatine phosphokinase isoenzyme (CKMB), intracranial pressure (ICP), ONSD, cardiac color ultrasound, acute physiology and chronic health evaluationII (APACHEⅡ ) and GCS were analyzed and compared between the two groups. The proportion and dosage of vasoactive drugs used at admission, daily fluid balance volume during hospitalization, total amount of sedative and analgesic drugs, and average daily dose were analyzed and compared between the two groups. The independent risk factors for CCS-related death were analyzed using multivariate logistic regression. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of the independent risk factors in CCS-related death. Results:In this study, 55.4% of the patients died of CCS. The ONSD, ICP change rate, right ventricular Tei index and NSE in the death group were higher than those in the survival group, with statistically significant differences ( P < 0.05), while the GCS in the death group was significantly lower than that in the survival group, with a statistically significant difference ( P < 0.01). ONSD ( OR = 23.890, 95% CI: 5.526-103.286, P < 0.001), GCS ( OR = 17.066, 95% CI: 1.476-197.370, P = 0.023) and ICP change rate ( OR = 0.060, 95% CI: 0.007-0.477, P = 0.008) were the independent risk factors for CCS-related death. The area under the ROC curve (AUC = 0.897) of ONSD combined with GCS in evaluating CCS-related death was larger than that of ONSD, ICP change rate alone and the corresponding AUC of 1/GCS (0.876, 0.785, 0.800, respectively), with the advantages of non-invasive, dynamic monitoring and low inspection costs. Conclusions:The mortality rate of CCS is high. ONSD, GCS and ICP change rates are independently correlated with the death of CCS patients. ONSD combined with GCS is an ideal indicator for clinical prediction of CCS-related death.

Objective To explore the effect of lentiviral vector-mediated somatostatin (SST) expression on seizures induced by hippocampal kindling in rats.Methods Adult Sprague-Dawley rats were randomly divided into the sham group (Sham),epilepsy group (EP),Lenti-pSyn-EGFP (LV-EGFP) group and Lenti-pSyn-SST-2A-EGFP (LV-SST) group.The rats in LV-EGFP group were subsequently electrically hippocampal kindled and LV-EGFP (5 μl) was injected into dentate gyrus (DG).The rats in LV-SST group were kindled and LV-SST (5 μl) was injected into the dentate gyrus (DG),medial entorhinal cortex (MEC) or amygdala (Amy).Seizure severity was evaluated and immunohistochemical staining was employed to detect the expression of SST,neuron specific nuclear protein (NeuN) and microtubule associated protein 2 (MAP2).Results The current values to the first stage V seizure of LV-SST (DG) group,LV-SST (MEC) group or LV-SST (Amy) group ((143.8±3.8)μA,(142.5±4.1)μA,(142.5±5.3) μA,respectively) were significantly increased compared with that of epilepsy (EP) group ((136.3±5.3)μA),and V stage current values of LV-SST groups in each stimulation day were higher than that of EP group except the fifth stimulation day (P<0.05).After kindling,SST expression and NeuN-positive neurons of EP group and LV-SST groups were less than that of Sham group in CA1,CA3 and DG.SST and NeuN neurons loss in LV-SST groups were less than that of EP group (P<0.05) and MAP2 immunohistochemistry stainings in LV-SST groups were higher than that in EP group.Conclusion Lentiviral vector-mediated somatostatin expression suppresses seizures and can rescue the neuronal damage of seizure induced by kindling in hippocampus,which may provide a new method of gene therapy for temporal lobe epilepsy.

Objective To observe the clinical efficacy of HE’s needling method (three ways for unblocking) in treating mild simple obesity due to dampness from spleen deficiency.Method Forty eligible subjects with mild simple obesity due to dampness from spleen deficiency were randomized into group A and group B, 20 cases in each group. Group A was intervened by mild unblocking method plus intensive unblocking method from HE’s needling method, and group B was by mild unblocking method plus warm unblocking method. The obesity-related indexes were observed before and after treatment, and the clinical efficacies were compared.Result The body weight and Body Mass Index (BMI) were significantly changed after intervention in the treatment group (P<0.05). The body weight was significantly changed after treatment in the control group (P<0.05). After treatment, there were no significant differences in comparing the obesity-related indexes (body weight, BMI, waist circumference, hip circumference, and waist-hip ratio) between the two groups (P>0.05). The total effective rate was 55.0% in the treatment group versus 10.0% in the control group, and the difference was statistically significant (P<0.01).Conclusion HE’s needling method is effective in treating mild simple obesity due to dampness from spleen deficiency, and mild unblocking method plus intensive unblocking method can produce a more significant efficacy compared to mild unblocking method plus warm unblocking method.

Objective To explore the effect of lentiviral delivery green fluorescent protein in different brain regions on the transfection of dentate gyrus neurons.Methods Lenti-pSyn-EGFP was stereotaxic injected into dentate gyrus (DG),Cornu Ammonis 1 (CAl) of hippocampus and medial entorhinal cortex (EC) of rats.All animals were perfused with 4％ paraformaldehyde.Their brains were cut into 30 μm sections which were performed with Nissl fluorescent staining.Results The resuts showed that the GFP positive cells in DG area of DG,CA1,EC,DG-EC groups were (18.0± 1.0),(17.0±0.6),(17.3±0.6),(18.3±0.6) respectively,and there was no statistical difference among each group(P＞0.05).Conclusion Lentivirus delivery in EC and CA1 both can transfect DG neurons.This is a useful method to transfect dentate gyrus neurons instead of injecting lentivirus into DG directly and avoid the lesion of DG.
