AIM: To investigate the effect of relieving liver-qi recipes(Radix Bupleuri,Radix Paeoniae Alba,Fructus Aurantii,etc.) on the neuro reproductive endocrine in female rats under psychologic stress. METHODS: The psychologic stress induced syndrome of liver-qi stagnation in female rats was established by tail pinch.The hypothalamus pituitary and serum levels of NE,DA,5 HT,5-HIAA,DOPAC,HVA and the serum FSH,LH,E2,T,P,PRL in rats of any groups were measured. RESULTS: The levels of NE in hypothalamus pituitary and FSH,LH,E2,P in serum of model rats were lower and the contents of DA,5-HT,5-HIAA in hypothalamus pituitary and in serum and NE,T in serum were significantly higher than those of the normal control.The serum P and LH in the complex group were elevated.The descending NE in hypothalamus pituitary and FSH,E2 in serum increased and the ascended DA,5-HT,5-HIAA in hypothalamus pituitary and NE,5-HT,T in serum significantly descresed in the shugan group and the complex group.The enhance of NE in hypothalamus pituitary and FSH,P in serum and the reduction of 5-HT in hypothalamus pituitary and 5-HT,NE,T in serum were also obversed in the bushen group. CONCLUSION: Regulating liver-qi and tonifying the kidney recipes could improve the function of neuro reproductive endocrine system which could be attenuated or disturbed by psychologic stress.

0.05), but serum levels of, SS, SP and VIP were higher than those of control group (P05). When the intensity reached 120dB, gastrointestinal transit was accelerated significantly(P

Objective: The bacteriostatic, antiviral, anti inflammatory and antipruritic effects of Mieryongkang Ointment (Rhizoma Coptidis, Radix Sophorae Flavescentis, Fructus Cnidii, Herba Violae, etc) in the treatment of vaginitis were investigated. Methods: By the methods of tube bacteriostatic test in vitro, histamine phosphate allergic pruritic tolerance in guinea pig, xylene induced ear acute inflammatory oedema of mouse and egg albumin caused foot swelling of rat, the pharmacological effects were observed. Results: Mieryongkang Ointment could inhibit and/or destory staphylococcus aureus, staphylococcus albus, gonococcus, trichomonad and human immunodeficiency virus in tube trial. It also increased the itching threshold value of histamine phosphate allergic pruritic tolerance in guinea pig and decreased the rates of swelling in ear acute inflammatory oedema of mouse induced by xylene and egg albumin caused in foot of rat after using the drug in skin. Conclusion:Mieryongkang Ointment has bacteriostatic, antiviral, anti inflammatory and relieving the itch.

The expression of phenylalnine ammonia lyase (LJPAL1) is closely related to the content of active compounds in Lonicera japonica. In this paper, a prokaryotic expression vector is constructed and LJPAL1 protein is expressed in E. coli. Three antigen sites were synthesized to peptide antigen and prepared polyclonal antibody of Anti-LJT-1, Anti-LJT-2 and Anti-LJT-3, separately. Antibody Anti-LJT-2 was screened using Western blotting. And indirect ELISA was built using Anti-LJT-2. The results of this study will be a base for honeysuckle chemical quality and evaluation kits.

Vorapaxar,a novel antagonist of the protease-activated receptor 1 (PAR-1 ),can inhibit the clotting process. Deuterium-labeled vorapaxar was required for the analysis of clinical sample as an internal stand-ard. Starting for unlabeled vorapaxar,four-step reactions including hydrolysis,condensation,transesterification and hydrogen-deuterium exchange were carried out to synthesize [D8]vorapaxar effectively for the first time. All intermediates and final products were confirmed by NMR and high resolution mass spectrometry (HRMS).Impor-tantly,the prepared [D8]vorapaxar could meet the requirements of sample analysis as the internal standard.

Objective:To evaluate the survival outcomes of radiotherapy in patients with newly-diagnosed metastatic head and neck squamous cell carcinoma (HNSCC) based on data from the Surveillance, Epidemiology and End Results (SEER) database.Methods:A total of 1226 patients newly-diagnosed with metastatic HNSCC between 2010 and 2015 were selected from the SEER database. There were 762 patients (62.1%) in the radiotherapy group and 464 patients (37.9%) in the non-radiotherapy group. Kaplan-Meier method was used to calculate the cancer-specific survival (CSS) and overall survival (OS). The effect of radiotherapy on survival was assessed by Cox multivariate regression and Propensity score-matched analyses (PSM). According to the results of multivariate analysis, the patients were further divided into low-, intermediate- and high-risk groups, and the effect of radiotherapy on survival was analyzed in different risk groups.Results:The median CSS and OS time of the whole group was 11.0 months and 10.0 months, respectively. For patients in the radiotherapy group and non-radiotherapy group, the median CSS time was 13.0 months and 6.0 months, and the median OS time was 12.0 months and 6.0 months, respectively. Multivariate analysis showed that age (CSS, P=0.045;OS, P=0.002), primary tumor site (CSS, P=0.021;OS, P<0.001), T stage (CSS, P=0.001;OS, P=0.002), N stage (CSS, P=0.002;OS, P<0.001), number of metastatic organs (CSS, P<0.001;OS, P<0.001), surgery (CSS, P<0.001;OS, P<0.001), radiotherapy (CSS, P<0.001;OS, P<0.001), and chemotherapy (CSS, P<0.001;OS, P<0.001)were the independent prognostic factors. After PSM, patients with and without radiotherapy in the low-,intermediate-,and high-risk groups, the 3-year CSS rates were 62.5% vs 23.5%( P=0.008), 22.4% vs 15.7%( P=0.001)and 10.5% vs 9.6%( P=0.203), respectively; the 3-year OS were 58.0% vs 20.8%( P=0.002), 19.8% vs 12.7%( P=0.001)and 7.0% vs 6.1%( P=0.166), respectively. Conclusion:Radiotherapy significantly improves CSS and OS in the low- and intermediate-risk groups, but patients in the high-risk group do not benefit from radiotherapy.

Objective:To assess the efficacy and toxicity of chemoradiotherapy in the treatment of early stage extranodal nasal-type NK/T-cell lymphoma (ENKTCL).Methods:Retrospective review was conducted for 174 patients with pathological proved early stage ENKTCL who were treated in the Department of Radiation Oncology, Peking University Cancer Hospital & Institute. The Kaplan-Meier survival analysis was adopted to calculate the local-regional control (LRC), overall survival (OS), and progression free survival (PFS), and the Log-rank test COX regression model were applied to univariate and multivariate analyses.Results:The patients in this study included 102 and 72 patients diagnosed with Ann Arbor stage-Ⅰ and stage-Ⅱ, respectively. Among them, two patients received radiotherapy alone and 172 patients were treated with combined chemoradiotherapy. The overall response rate of all the patients was 94.2%, with a complete response (CR) rate of 87.9% (153). Furthermore, the rates of 5-year OS, PFS, and LRC were 87.3%, 83.1%, and 91.9%, respectively. The most common toxicities during the chemotherapy and radiotherapy included myelosuppression and oral mucositis, with grade ≥ 3 myelosuppression and grade ≥ 3 oral mucositis accounting for 62.1% and 10.9% of all patients, respectively. As shown by multivariate analysis, the adverse prognostic factors for OS included age > 60, B symptoms, and stage Ⅱ, while the adverse prognostic factors for PFS included age > 60 and stage Ⅱ. Meanwhile, the PFS rate was significantly improved by increasing the radiation dose (≥ 50 Gy vs.<50 Gy), and the 5-year PFS rates of the two groups were 83.5% and 76.5%, respectively [hazard ratio ( HR) 0.374; 95% CI, 0.169-0.826; P=0.015]. Conclusions:A good therapeutic effect can be achieved for early stage NK/T-cell lymphoma and the toxicities after combined chemoradiotherapy can be tolerated.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.
