China Pharmacy 2005;0(23):-
OBJECTIVE: To establish a RP-HPLC method for the content determination of gentiopicroside in Xiaofeng pills.METHODS: The chromatographic column was DiamonsiLTM C18(150 mm?4.6 mm,5 ?m) column with mobile phase consisted of acetonitrile-water(11 ∶ 89) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 254 nm.RESULTS: The linear range of gentiopicroside were 0.205 6~2.056 0 ?g (r=0.999 9) with an average recovery of 96.18%(RSD=1.55%,n=6).CONCLUSION: The method is simple,rapid and accurate for the quality control of Xiaofeng pills.
2.Magnetic resonance imaging in the evaluation of cervical cancer
Journal of International Oncology 2014;41(6):450-454
Magnetic Resonance Imaging (MRI) can form a three-dimensional positioning anatomical imaging.By comparing the tumor volume and signal intensity changes,there is great value of MRI in the assessment of the efficacy of cervical cancer.With the development of imaging,magnetic resonance diffusion weighted imaging (DWI),magnetic resonance spectroscopy (MRS) can provide qualitative and quantitative information of the cellular level,which reflects changes in the treatment of tumor cells.Magnetic resonance imaging can predict early locally advanced cervical cancer neoadjuvant chemotherapy,thus providing an important basis for individualized treatment of patients.

Purpose To study the pathologic types and subtypes distribution of 645 cases of lymphoma in Xinjiang. Methods Clini-cal data of lymphoma from April 2008 to march 2013 in the people’s hospital of Xinjiang Uygur autonomous region in Xinjiang were col-lected and reviewed, including morphological, immunohistochemical and clinical characteristics. According to the WHO classification all the cases were reappraised. Results Of the 645 cases, 558 cases (86.51%) were non-Hodgkin’s lymphoma (NHL) and 82 ca-ses (12.71%) were Hodgkin’s lymphoma (HL). Among NHL cases, 448 cases (80.29%) were B-cell neoplasms and 110 cases (19.71%) were T/NK-cell neoplasms. The commonest subtype was diffuse large B-cell lymphoma (258 cases, comprising 40% of all lymphomas) and extranodal NK/T-cell lymphoma (41 cases, comprising 6.36% of all lymphomas) in B cell lymphoma and T/NK cell lymphoma. Burkitt’s lymphoma and lymphoblastic leukemia/lymphoma were predominanly Uyghurs, but mantle cell lymphoma, follicu-lar lymphoma and extranodal marginal zone lymphoma of mucosa associated lymphoid tissue were predominanly Hans. The most com-mon subtypes of Hodgkin’s lymphoma are mixed cellularity, nodular sclerosis and lymphocyte-rich classical Hodgkin’s lymphoma. Sub-types distribution of Hodgkin’s lymphoma has a certain difference in the different ethnic groups, the age of onset did not present twin peaks and the highest proportion was children. Conclusion The lymphoid neoplasms of Xinjiang displayed some ethnic features simi-lar to those reported in literature as well as other regions of China, whereas the distribution of some subtypes showed some differences.

Objective To explore the value of predicting ovarian response using the antral follicle count in in vitro fertilization(IVF) cycle. Methods 54 patients in our infertility treatment center were observed, in which 6 patients had poor ovarian response and the other 48 patients had good ovarian response. The clinical data, duration and efficacy of treatment were compared between the two groups. Results The mean number of antral follicles and retrieved oocytes in the third day of menstruation in good ovarian response group was significantly higher than that in poor ovarian response group. The clinical pregnancy rate of the good ovarian response group was better than that of the poor one. Conclusions Monitoring the antral follicle count in both ovaries using vaginal ultrasound may predict ovarian response in IVF in the third day of menstruation.

Objective To investigate the effect of caspase-2 and caspase-3 in cisplatin-induced apoptosis in cisplatin-resistant and-sensitive human ovarian cancer cell lines, A2780/DDP and A2780. Methods A2780 and A2780/DDP cells were incubated with various doses(0,5,10,20,40?M) of cisplatin for 24,48 and 72 hours, respectively. The protein expressions of caspase-2 and caspase-3 in the ovarian cancer cell lines were detected by immunohistochemical technology. The apoptotic rate of the ovarian cancer cell lines was determined by TUNEL. Results After cisplatin treated, apoptotic rates of both 2780 and A2780/DDP cell lines increased in time-and dose-dependent manners (P
