Objective To discuss the effects of BuShenHuoXue on ovarian granulose cell apoptosis of DOS rats induced by GTW. Methods Sixty 12 -week -old female SD rats were randomly divided into 6 groups:control, model GTW,low dose of BuShenHuoXue Formula, middle dose of BuShenHuoXue Formula, high dose of BuShenHuoXue Formula, and LiuWeiDiHuang soup group. The ovary index, pathomorphological configuration,the level of E_2 and FSH in blood serum, and the expression of granular cell apoptosis protein Bcl - 2, Bax and Caspase - 3 was obserred after giving rats the different drugs separately. Results The expression of Bcl - 2, Caspase - 3 : as compared with control,the model, BuShenHuoXue low dose had a significant difference ( P

Objective To observe the clinical efficacy of integrated traditional Chinese and western medicine in the treatment of infertility resulted from ovulation dysfunction.Methods 106 patients with ovulation dysfunction were divided into observation group(n =56)and control group(n =50)in stratified randomization.Both two groups were given clomiphine to induce ovulation.Futhermore,the observation group was added Chinese herb recipe.Both two groups were treated for 3 menstruations.The basic body temperature,follicle development,endometrium depth, ovulation and pregnancy were observed.The serum levels of E2,LH and FSH were detected.Results There was no difference in the basic body temperature between the two groups(P >0.05).After treatment,the basic body tempera-ture of the observation group was obviously superior to that of the control group(χ2 =0.627,P =0.049),there was no difference in the endometrium depth between the two groups(P >0.05).After treatment,the endometrium in the observation group was significantly better than before treatment and that in the control group(t =5.132,P <0.05). After treatment,the serum levels of E2 ,LH and FSH in the observation group were all improved more obviously than those in the control group(t =6.489,5.167,6.035,all P <0.05).The efficacy of the two groups was higher than that of the control group(χ2 =6.049,P =0.048).Conclusion The method of integrated traditional Chinese and western medicine can promote the development of follicle and endometrium,improve levels of E2,LH and FSH,enhance ovula-tion rate and pregnancy rate in the treatment of infertility resulted from ovulation dysfunction,which is worthy of clini-cal promoting.

Objective To investigate the physics technique and quality assurance (QA) during radiotherapy in the institutions from the East Guangdong province,aiming to provide reference for the construction of radiotherapy discipline and rational allocation of resources in the primary hospitals from the eastern Guangdong province.Methods From March 15 to May 20,2016,the general conditions,radiotherapy equipment,available technique and quality assurance (QA) in the medical institutions from eastern Guangdong were investigated and analyzed by online combined with on-spot surgery.Results There were 8 institutions which provided radiotherapy with 966 ward beds,a daily capacity of 632 patients and 222 radiotherapy practitioners.Radiotherapy equipment included 12 linear accelerators,5 after-loading devices,1γ-knife,8 CT simulators and 9 radiotherapy planning systems.Five institutions performed IMRT/VMAT,IGRT and ART.Dose verification was performed before precision radiotherapy delivery in all institutions except for 1 center.QA procedures were missing for the linear accelerators,CT simulators and after-loading devices.Short-term advanced studies and hand-by-hand teaching were the main approaches for staff professional training.Conclusions The resource allocation for radiotherapy in the medical centers from the eastern Guangdong province is scarce.The technique and QC levels greatly differ among different institutions.Standard QA protocols are urgently to be established and implemented.Extensive attentions should be paid to the the professional training for technicians.

ObjectiveTo identify the chemical components of Houpo Wenzhongtang in vivo and in vitro and to analyze the pharmacokinetic properties of the index components in rats with deficiency-cold of spleen and stomach. MethodThe chemical components of Houpo Wenzhongtang was analyzed and identified by ultra performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry（UPLC-Q-TOF-MS/MS）. Six rats were randomly selected from 18 SD rats as the blank group， and the remaining rats were given lard and cold vinegar for a long time to construct a rat model with deficiency-cold of spleen and stomach. After successful modeling， the rats were randomly divided into the model group and Houpu Wenzhongtang group（13.5 g·kg^-1， calculated as crude drug）. The administration group was given the corresponding dose of Houpu Wenzhongtang by gavage， and the blank group and the model group were given the same amount of distilled water by gavage. Enzyme-linked immunosorbent assay（ELISA） were used to measure gastrin（GAS） and motilin（MTL） levels in each group. At the same time， plasma samples were collected at different time points after administration， and blood-entry prototype components and metabolites of Houpo Wenzhongtang were analyzed by UPLC-Q-TOF-MS/MS. On this basis， plasma concentrations of magnolol， honokiol， alpinetin and hesperidin in Houpo Wenzhongtang were determined by ultra performance liquid chromatography coupled with triple quadrupole/linear ion trap mass spectrometry（UPLC-QTRAP-MS/MS）， and the pharmacokinetic parameters were calculated using DAS 2.0 software. ResultA total of 79 chemical components， including 44 flavonoids and 11 lignans， were identified in Houpo Wenzhongtang. Meanwhile， 18 blood-entry prototype components and 27 metabolites were identified， the main metabolic pathways of metabolites were glucuronidation， sulfation， oxidation and hydrolysis， and phase Ⅰ and phase Ⅱ were the two primary forms of metabolism. Pharmacokinetic results showed that among the four index components， the time to peak（t_max） values of magnolol and honokiol were consistent and exhibited similar drug metabolism characteristics， the t_max of alpinetin was the shortest， and the absorption rate was the fastest， which had the earliest peak plasma concentration levels， and hesperidin had the shortest mean residence time（MRT_0-t） and the highest metabolic rate in rats. ConclusionThis study clarifies the blood-entry prototype components and their metabolites of Houpo Wenzhongtang in the rat model of deficiency-cold of spleen and stomach， and reveals the pharmacokinetic characteristics of the main active ingredients， which can provide a scientific basis for the study of pharmacodynamic material basis of this formula and its clinical application in treating the syndrome of deficiency-cold of spleen and stomach.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
