RESUMEN
Objective To establish a gas chromatography for simultaneous determination of camphor residue and borneolum content in Qingchang Suppository. Methods Gas chromatograph method was used. The chromatographic column was Agilent capillary column(30 m×0.25 mm×0.25 µm). The column temperature was 140 ℃. The sample injection temperature was 250 ℃. The FID detector temperature was 250 ℃. Results Camphor，borneol and isoborneol content showed good linear in the extent of 0.0299~1.497(r=1.000), 0.0205~1.025(r=1.000), 0.0097~0.4830 µg (r=1.000). RSDs of precision，stability and repeatability test results were less than 2%. The recovery was 99.7%, 101.0%, 102.5%. Conclusion This method is simple and quick with accurate result, which could be used for the content determination of Borneol in Qingchang Suppository.
RESUMEN
Objective To improve the quality of prescriptions and promote the rational drug application of Dingqing Tablets by investigating the outpatient prescriptions in a tertiary A hospital. Methods A total of 4 796 prescriptions of outpatient pharmacy patients from August 1, 2020 to August 1, 2021 were extracted from the hospital information system by the hospital information software, focusing on the analysis of indications, usage and dosage, drug interaction, etc. Results 10 departments including hematology department and geriatrics department were used Dingqing Tablets, and the irrationality was mainly manifested in the superposition of drug flavors and drug interactions. Conclusion Dingqing tablets were widely used in clinic and had remarkable curative effect. However, there are certain risks in the use of Dingqing tablets. It is necessary to add medication education and supervision to promote the safe and rational use of drugs in clinic.
RESUMEN
Objective To evaluate the value of DNA quantitative analysis in diagnosis of breast tumor.Methods The data of 128 cases diagnosed with breast disease from Feb.2005 to Jan.2006 in Department of Pathology in Wuhan Center Hospital were collected,among whom 72 cases had benign breast lesion,10 cases had boundary breast lesion and 46 cases had malignant breast disease.Automated DNA imaging cytometry was used to identify DNA indexes of the 128 cases.Results The positive rate was 1.39％ (1/72),30.00％ (3/10) and 78.26％ (36/46) respectively in benign breast lesion,boundary breast lesion and malignant breast disease.The difference had statistical significance (P ＜ 0.05).In invasive ductal breast cancer,the positive rate was 57.14％ (4/7),76.47％ (13/17) and 100％ (18/18) respectively for breast cancer of grade Ⅰ,Ⅱ and Ⅲ.Conclusion Automated DNA imaging cytometry is of some value in analyzing the malignant grade of breast cancer and predicting the prognosis of breast diseases.
RESUMEN
Objective To compared the clinical efficacy of laparoscopic-assisted vaginal and laparotomy in the treatment of early endometrial cancer.Methods CLinical data of 180 patients with endometrial cancer were analyzed retrospectively,which were randomly divided into two groups:The laparotomy group were underwent conventional abdominal hysterectomy and pelvic lymphadenectomy;Laparoscopic group were underwent laparoscopic-assisted vaginal hysterectomy and pelvic lymph node dissection.Operative time,blood loss,recovery time of gastrointestinal function,length of stay,the number of harvested lymph nodes,complications were compared.Results There were no significant differences in operative time,blood loss,the number of lymph nodes cleaned up between two groups(P ＞0.05).Recovery time of gastrointestinal function,and length of stay in the laparoscopic group was significantly shorter than the laparotomy group,the differences were statistically significant(t =2.898,2.564,P ＜0.05).The complication rates(11.0％ vs 19.1％) were no significant difference(P ＞ 0.05).Following up for 3 months to 27 months,recurfence rates(6.6％ vs 5.6％) and survival rates(98.9％ vs 97.8 ％) were no significant difference(all P ＞ 0.05).Conciusion The clinical efficacy of laparoscopic-assisted vaginal surgical treatment for early endornetrial cancer was significantly superior to laparotomy surgery with advantage of minimally invasive,quick recovery.
RESUMEN
Objective To study the clinicopathological and immunohistochemical features of squamous cell carcinoma (SCC) of breast.Methods Three cases with breast SCC were studied by analyzing their clinical data,histomorphology and immunophenotype.The related literature was reviewed.Results The patients were all females.Their ages ranged from 37 to 50 years,with 43 years as the medium.The tumor diameter was 2-9 cm,with 4.3 cm as the medium.Metastasis of axillary lymph node was found in one case,accounting for 33％ of the total.Two cases had painless lumps in their left breasts.One case had a lump with local inflammation,pain and ulcer in her left breast.Histopathological examination showed the polygonal and spindle-shaped cells with eosinophilic cytoplasm were found in cancer nest,as well as the prominent intercellular bridges and keratin pearls were found to be rich in three cases.Interstitial fibrosis with hyalinization and lymphocytic infiltrate around the tumor was also found.Immunohistochemistry showed ER,PR,HER-2,CK18 and SMA were negative while CK,CK14,CK5/6,p63,S-100 and vimentin were positive.Conclusions SCC is a rare subtype of breast carcinoma with distinct histopathological and morphological features.SCC is a typical basal-like breast carcinoma,and the majority of breast SCC appear a basal-like immunophenotype with poor prognosis.
