Objective To explore the influence of the extract of wen-pi-tang on the memory and SOD and MDA of normal mice and cerebral ischemia reperfusion mice.Method The mice were divided into normal group,sham operation group,model group,aqueous extract and alcohol extract of wen-pi-tang (1.0 g/kg,0.5 g/kg,0.25g/kg).Model mice with cerebral ischemia reperfusion were made by blocking bilateral common carotid artery.The influence on memory behavior of normal mice and mice with cerebral ischemia reperfusion were tested by gavage for 10 days with extract of wen-pi-tang through step-down and step-through tests.Then SOD activity and content of the MDA were tested.Result In step-down test,compared with normal group,extract of wen-pi-tang with all doses made normal mice' latency longer,error frequency fewer,with high does clearest (P＜0.05)(latency:(187.17±99.00) s,(270.73±44.73) s,(260.45±63.78) s,error frequency(1.75± 1.71) times,(0.45±0.69) times,(0.75±0.97) times) ;in step-through test,compared with normal group,aqueous extract with high and middle doses and alcohol extract with longe doses could made latency of cerebral ischemia reperfusion mice longer and error frequency fewer (latency(157.15±84.91) s,(250.63±58.98) s,(251.12±78.22) s,(245±84.82) s,error frequency(2.15± 1.22) times,(0.75±0.89) times,(0.75± 1.16) times,(0.625 ±0.92) times) (P＜0.05) ; extract of wen-pi-tang with high and middle does increased SOD activity obviously compared with normal group(P＜0.05),and the content of MDA was obviously lower compared with normal group(P＜0.05,P＜0.01).Conclusion Extracts of wen-pi-tang can improve the memory function of normal mice,and the memory of cerebral ischemia reperfusion mice.The mechanism can be related to the increase of SOD activity and the decrease of the content of MDA.

Objective: To observe effects of Ficus carica polysaccharide (FCPS) on tumor bearing mice. Methods: The model of S 180 bearing mice and EAC bearing mice were established, tumor cells were inoculated under the skin of right armpit or in abdominal cavity in mice after FCPS being administered orally for ten days, to calculate inhibitive rate of tumor and survial time of mice. Results: FCPS could significantly prevent the growth of tumor, there were no effects on survival time of mice.Conclusion: FCPS had a good antineoplastic effect. It is worth further study.

Objective To analyze the application of dexmedetomidine in intracranial arterial stenting and its influence on the serum myocardial enzyme ,cardiac troponin I(cTnI) and left ventricular ejection fraction (LVEF). Methods From March 2015 to March 2017,94 cases with intracranial arterial stenting in the People's Hospital of Lishui were divided into control group and observation group by the random number table method ,with 47 cases in each group.The control group was treated with conventional anesthesia ,the observation group was treated with dexme-detomidine.The enzyme creatine phosphate kinase isoenzyme (CK -MB),creatine phosphate kinase (CK),cTnI, LVEF,inflammatory factor, neural function, brain oxygen metabolism and complications in the two groups were compared.Results After surgery,the CK-MB,CK,cTnI levels of the observation group were lower than those of the control group[(35.27 ±4.41) U/L,(488.30 ±61.03) U/L,(3.85 ±0.49) μg/L vs.(46.40 ±5.79) U/L, (611.21 ±76.40)U/L,(4.72 ±0.59)μg/L],the LVEF of the observation group was higher than that of the control group[(45.60 ±5.72)%vs.(43.12 ±5.39)%],the differences were statistically significant (t＝10.484,8.619, 7.777,2.163,all P＜0.05).The interleukin -6(IL-6) and interleukin -8(IL-8),tumor necrosis factor -α (TNF-α),S-100β,specificity enolization enzyme(NSE),cerebral metabolic rate of oxygen(ERO2),arterial blood oxygen saturation(PaO2),carotid venous blood oxygen saturation (SjvO2) of the observation group were better than those of the control group(t＝5.794,6.177,15.065,6.964,5.606,3.147,2.116,2.807,all P＜0.05).The inci-dence rate of complication of the observation group was lower than that of the control group (χ2＝17.091,P＜0.05). Conclusion Application of dexmedetomidine in intracranial arterial stenting can protect myocardium , inhibit the serum levels of myocardial enzyme ,cTnI rise,and is conducive to the recovery of LVEF.

Objective: The objective of this study was to identify the risk factors for postoperative pathological escalation of endometrial cancer in patients with a pathologic diagnosis of endometrial intraepithelial neoplasia (EIN) before surgery. Some of the clues from the preoperative assessment were used to build a nomogram to predict the likely pathological escalation after surgery, and to explore the feasibility of sentinel lymph node biopsy in these patients with possible pathological escalation. Methods: This was a retrospective analysis of patients who underwent surgical treatment for EIN diagnosed before surgery between 2018 and 2023 in The Obstetrics and Gynecology Hospital of Fudan University. parameters including clinical, radiological and histopathological factors were analyzed by univariate and multivariate logistic regression to determine the correlation with pathology upstaging. A nomogram based on the multivariate results was developed to predict the probability of pathology upstaging. A total of 729 patients were included, divided into training set and validation set. 484 patients were used to build the model. This nomogram was subsequently validated using 245 patients. Results: Upstaging to endometrial carcinoma occurred in 115 (23.8 percent) of 484 women treated between 2018 and 2023 in training set. A lager endometrial thickness (at least 15 mm), menopause, hypertension, HE4, and endometrial blood were significantly associated with upstaging. A nomogram developed using these factors demonstrated good predictive performance (area under the receiver operating characteristic curve (AUC)=0.6808; 95% confidence interval [CI]=0.6246–0.7369). The nomogram showed similar predictive performance in the validation data set, based on another 245 women (AUC=0.7821; 95% CI=0.7076–0.8567). Conclusion This study developed a novel nomogram based on the 5 most important factors, which can accurately predict invasive cancer. It is common for women with preoperative diagnosis of EIN to experience pathological progression to endometrial cancer. For some patients with postoperative pathological escalation, we found lymph node metastasis. This nomogram may be useful to help doctor decide whether to perform sentinel lymph node biopsy for surgical staging in these EIN patients. According to the nomogram, simultaneous sentinel lymph node biopsy in patients with high probability of postoperative pathological upgrading can provide better guidance for postoperative adjuvant treatment of endometrial cancer and avoid the occurrence of secondary surgery.

Background: Several risk factors have been identified that compromise the treatment outcome in patients with early-to-mid-stage cervical cancer (CC) who are primarily treated with radical surgery. However, there is no report on the impact of intraoperative frozen pathology examination of vaginal margins on the prognosis of patients with CC. This study aimed to conduct a randomized controlled trial (RCT) to determine whether selective vaginal resection can reduce the incidence of operative complications and the risk of postoperative radiotherapy. The impact of the length of the vagina removed in radical hysterectomy (RH) on prognosis and quality of life (QoL) for IB2–IIA2 CC patients will be investigated. Methods A multicenter, non-inferiority, RCT at 7 institutions in China is designed to investigate the effect of intraoperative frozen pathology exam of vaginal margin in RH on the survival outcomes for patients with IB2–IIA2 CC. Eligible patients aged 18–70 years will be randomly assigned online by one-to-one random allocation to receive intraoperative frozen pathology exam of vaginal margin or not. If frozen pathology indicates positive margin, continue resection of 1 centimeter of vaginal tissue until negative margin is achieved. The primary end point is 2-year disease-free survival (DFS). Adverse events (AEs) caused by further vagina resection, 5-year DFS, 2-year overall survival (OS), 5-year OS and AEs caused by radiotherapy and QoL are secondary end points. A total of 310 patients will be enrolled from 7 tertiary hospitals in China within 3-year period and followed up for 5 years.Trial Registration: Chinese Clinical Trial Registry Identifier: ChiCTR2000035668
