OBJECTIVETo explore the best approach to treatment of cesarean scar pregnancy (CSP).
METHODSA total of 138 patients with CSP treated between January and December, 2013 were retrospectively analyzed. The patients were treated with conservative drug therapy, direct curettage, uterine curettage after embolization, or open or transvaginal surgery. The amount of blood loss, proportion of patients with blooding loss greater than 50 mL, hospitalization days, and hospitalization expenses were compared among the groups.
RESULTSThe median volume of blood loss was 370 mL in the conservative treatment group, 59 mL in direct curettage group, 67 mL in interventional therapy group, and 1425 mL in the surgical group, and the proportion of patients with blood loss over 50 mL was 76.9%, 38.8%, 27.5%, and 100% in the 4 groups, respectively. The midian hospital stay of the 4 groups was 9.0, 4.0, 6.0 and 10.0 days, with median hospitalization expenses of 12281.0, 3843.5, 14805.0, and 17202.2 RMB Yuan, respectively. All these data were significantly different among the 4 groups (P<0.05).
CONCLUSIONDirect curettage surgery should be encouraged for treatment of CSP. Embolization therapy can reduce the risk of bleeding but is associated with potential complications and more costly, and should be performed with caution. Open or trasnvaginal surgery can be considered in difficult cases of CSP, and its combination with interventional therapy is an option to better preserving the uterus.

The expression of stretch-activated potassium channel TREK-1 mRNA and protein of hypertrophic myocardium was measured. Using a model of hypertrophy induced by coarctation of abdominal aorta in male Wistar rats, the expression of TREK-1 mRNA and protein was detected by using semi quantitative RT PCR and Western blot respectively. At 4th and 8th week after constriction of the abdominal aorta, rats developed significant left ventricular hypertrophy. As compared to sham operated group, stretch activated potassium channel TREK-1 mRNA was strongly expressed and protein was up regulated in operation groups (P<0.05). It was concluded that the expression of TREK 1 was up regulated in hypertrophic myocardium induced by chronic pressure overload in Wistar rats.

Objective:Gastric adenocarcinoma of the fundic gland type (GA-FG) is rare and often occurs in patients who are not infected with Helicobacter pylori. The current study analyzed and summarized the clinical, endoscopic, and pathological features of GA-FG, in an effort to improve its diagnosis. Methods:Patients who were diagnosed with GA-FG and treated with endoscopic submucosal dissection (ESD) resection at the Department of Gastroenterology, First Affiliated Hospital of Zhejiang Chinese Medical University from January 1st 2020 to October 1st 2022 were included in the study. Their clinical manifestations, endoscopic features, pathological immunohistochemistry, and other characteristics were analyzed.Results:A total of 14 patients with GA-FG were included in the study, 5 males and 9 females, with a mean age of 59 years. Most had no substantial clinical manifestations. Twelve patients were H. pylori-negative, all patients underwent ESD resection, and all patients survived during the follow-up period of 13±9 months. Eleven patients had postoperative endoscopic follow-up records, and no recurrence was detected. Fifteen lesions were detected (2 were present in 1 patient). Twelve were located in the upper 1/3 of the stomach, 10 were ≤ 1 cm in diameter, 12 had a morphology of type 0-Ⅱa, 8 had visible discoloration changes, and 12 had visible vasodilation on the surface. Magnified endoscopy and narrow-band imaging indicated that 12 of the lesions had enlarged marginal crypt epithelium, without any obvious microvascular pattern abnormalities and no obvious borderline. After resection the pathological specimens were all without vascular infiltration, and there was no atrophy of the mucosa at the edge of the lesion. In immunohistochemistry analyses MUC-2 was negative in all cases. MUC5AC was negative in 11 cases, MUC-6 was positive in all cases, and Ki-67 was ≤ 5% in 12 cases. Conclusions:GA-FG is a newly identified type of gastric cancer with low malignancy and a good prognosis. Characteristic discoloration and surface dilated vessels are often evident endoscopically. Enlarged marginal crypt epithelium and no visible boundary lines are often apparent in magnification endoscopy and narrow band imaging.

Dioscoreae Rhizoma formula granules are made from decoction pieces by decocting, extracting, separating, concentrating, drying and granulating, which have the advantages of simple dispensing, convenient use and easy to take without decoction. However, because Dioscoreae Rhizoma is rich in starch and mucus components, its extract powder and formula granules are poorly soluble and difficult to dissolve or disperse completely within 5 min, and the insoluble material is difficult to dissolve completely even after 24 h in water, which affects the quality evaluation of the formula granules and medication psychology of patients. Therefore, by studying the dissolution process and mechanism of Dioscoreae Rhizoma extract and its formula granules, it was found that the special chemical composition of Dioscoreae Rhizoma, the denaturation of starch and its compounding with protein and other substances during the high temperature extraction process, and the contraction of coating membrane during the spray drying process were combined to form the special microstructure of coating membrane covering starch granules, and it is the root cause of poor solubility of Dioscoreae Rhizoma formula granules. Based on the research on the structure, property and function of the powder, this paper proposed a technical strategy to improve the solubility of Dioscoreae Rhizoma formula granules by powder modification process, and experimentally demonstrated that the modified Dioscoreae Rhizoma formula granules could completely dissolve within 2 min, which solved the technical problem and could provide reference for the improvement of solubility of other similar varieties, and promote the high-quality development of traditional Chinese medicine formula granule industry.

OBJECTIVE To evaluate the cost-effectiveness of clopidogrel versus aspirin monotherapy regimens for secondary prevention of ischemic stroke and to provide economic evidence and reference for clinical medication and decision-making. METHODS Based on the CAPRIE trial, a Markov model was constructed; the probabilities of risk events, health utility values, and costs of risk event management were obtained from relevant literature. The cycle length was 6 months, and the time horizon was 10 years. A discount rate of 5% per year was applied. The primary outcomes were total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). Cost-utility analysis was performed for above 2 regimens by using TreeAge Pro software. The one-way sensitivity analysis, probabilistic sensitivity analysis and scenario analysis were conducted to validate the robustness of the analyses. RESULTS Compared with the aspirin regimen (325 mg/d of CAPRIE trial dose), the ICER values of clopidogrel regimen for secondary stroke prevention for 10 years, 20 years and 30 years were 4 284.06, 4 201.20 and 3 986.78 yuan/QALY, respectively, which were E-mail:liuxiaoyanrj@sjtu.edu.cn all less than the willing-to-pay (WTP) threshold of one time 。 China’s per capita gross domestic product (GDP) in 2021. E-mail:scilwsjtu-wb@yahoo.com Compared with the aspirin regimen (clinically recommended dose in China, 100 mg/d), the ICER values of clopidogrel regimen for stroke secondary prevention for 10 years, 20 years and 30 years were 58 238.27, 42 164.72 and 36 164.77 yuan/QALY, respectively, which were all less than WTP threshold. When comparing with aspirin regimen of 325 mg/d, results of one-way sensitivity analysis showed that the cost of clopidogrel and aspirin, probability of the first recurrence of ischemic stroke were sensitive factors of model. Results of probabilistic sensitivity analysis showed that when WTP was set at one time GDP per capita in China in 2021, clopidogrel had a probability of being cost- effective of about 66.5%. Results of scenario analysis showed that neither changing the time horizon to 10, 20 or 30 years nor using different doses of aspirin (50, 100, 150, 200 or 250 mg/d) would not alter any conclusions. CONCLUSIONS Compared with aspirin monotherapy, clopidogrel monotherapy is more cost-effective for secondary prevention of ischemic stroke.
