OBJECTIVE:To gain a clear idea of difference of drug requirement and DDD between senile women and men patients,so as to provide a scientific basis for safely,effectively,economically and rationally preventing and treating diseases of senile patients and improving their quality of life METHODS:A 2-year(1998～1999)prescription database,which was set up by PRESCRIPTION ANALYSIS research group of 22 hospitals in Beijing,was used for this study Information of senile out-p_atients(≥60 years old)was collected and analysed Foxpro software was used for statistics and analysis RESULTS:The prescription rate for senile male patients was 11 6%,whereas that for senile female patients was 8 3% Proportion of injection for per hundred male out-patients was 17 0% and that for female patients was 20 4% The main kinds of drugs used for both male and female patients were cardiovascular drugs and vitamins,the DDDs of which were lower than those defined by WHO and drug directions,however,the DDDs for male patients were higher than those for female The rate of consultation for cardiovascular disease was high in both sexes Prostate diseases in senile male patients and diabetes in female should be given more concern The drugs used for both sexes accorded with National Essential Drugs List(men 85%;women 87 5%) CONCLUSIO_N:The rate of prescription and DDDs for senile male patients were higher than those for female,however,the proportion of injections for per hundred male patients was lower than that for female

Obstructive sleep apnea hypopnea syndrome(OSAHS)is a serious health hazard in children.It can cause damage to multiple systems, including cardiovascular, metabolic, endocrine and neurocognitive systems, especially for cognitive impairment.OSAHS may cause sleep fragmentation and intermittent ventilation abnormalities due to repeated partial or total upper airway obstruction, resulting in hypoxemia and hypercarbia, affect attention, intelligence, memory, language, executive function, etc.

Objective To clarify the features of malignant ovarian neoplasms arising from ovarian endometriosis Methods A total of 26 women with malignant ovarian neoplasms arising from ovarian endometriosis were analyzed retrospectively Results Dysmenorrhea and pelvic mass were the most common clinical features Among 18 cases who underwent B ultrasound or color doppler ultrasound examination, solid foci in the pelvic masses were found in 10 cases The main histologic types of ovarian malignancy were endometrioid adenocarcinoma and clear cell carcinoma Microscopically atypical endometriosis with the tumors were found in 15 cases International Federation of Gynecology and Obstetrics stage:stage Ⅰ 21(81%)cases,stage Ⅱ 3(12%)cases,stage Ⅲ 2 (8%)cases Conclusions Clinical diagnosis of malignant ovarian neoplasms arising from ovarian endometriosis in early stage is difficult, and B ultrasound examination is more valuable for diagnosis It is suggested that close serutiny of endometrial hyperplasia, cellular atypia and malignancy in ovarian endometriosis be essential to understand the origin and development of malignant neoplasms arising from ovarian endometriosis

Objective To find antitumor cOnstituents from Tripterygium hypoglaucum.Methods The chloroform extract of T.hypoglaucum was separated by silica gel column chromatography and preparative HPLC.The structures of compounds isolated were identified by spectral analysis and chemical evidence.Results Seven compounds were isolated and identified as rhein ethyl ester(1),chrysophenol(2),physcion(3),emodin(4),wilfordine(5),wilforgine(6),and wilforine(7).The cytotoxic activities of the compounds against cancer cell lines were assayed.Conclusion Compound 1 is a new natural compound with strong activities against human cancer cell lines (A2780 and OVCAR-3).Compounds 2-4 are isolated from this genus plants for the first time.The possible structure-activity relationship among compounds 1-4 shows that the methoxy group or oxyethyl moiety might be responsible for the cytotoxity.

OBJECTIVE:To optimize the formulation of Compound tripterygium hypoglaucum gel. METHODS:Using the comprehensive score(total score was 15.0)composed by forming property,glossiness,uniformity,viscosity,pH,spreadable prop-erty and stability as indexes,using the usage amount of carbomer 940,propylene glycol,triethanolamine and extracts in formula as study factors,orthogonal test was designed to optimized the formulation of Compound tripterygium hypoglaucum gel,and the verification test was conducted. RESULTS:The optimal matrix formulation was as follow as carbomer 9401.0 g,azone 2.0 g,so-dium bisulfite 0.4 g,extracts 50 mL,propylene glycol 10 g,triethanolamine 1.0 g,adding water to 100 g. The average comprehen-sive score of the gel in verification test was 14.8 (RSD=1.35%,n=3). CONCLUSIONS:The optimized formulation of Com-pound tripterygium hypoglaucum gel shows good forming property,the quality meets the requirements.

Myelodysplastic syndromes ( MDS ) represent a heterogeneous group of clonal hematopoietic disorders with diverse clinical course .Because of the heterogeneity and the lack of molecular markers to monitor disease progression, clinical management of MDS patients is challenging .Recently, with the development of molecular analysis techniques , an increasing number of MDS related molecular biomarkers have been reported.In this review, we will discuss the clinical applications of the newly reported molecular makers in terms of diagnosis , prognosis and treatment.These markers may improve the diagnosis and prognostic assessment systems of MDS , which may potentially be used to guide decision making in the individual therapy.

The mutation status of calreticulin gene (CALR) is helpful for the diagnosis of JAK2 / MPL mutation-negative myeloproliferative neoplasms (MPN), and is closely related to the MPN progression and prognosis.Currently, Sanger sequencing, PCR-fragment analysis, high resolution melting, Taqman RQPCRand the next generation sequencing have been reported to be used to detecting the CALR gene mutations.A proper method for CALR mutation detection and a right laboratory diagnostic procedure according to the MPN-related molecular markers will facilitate the rapid and effective diagnosis and treatment of MPN.

Objective To investigate operation time on biliary duct stone with acute gallstone pancreatitis.Methods The clinical data of 44 patients with acute gallstone pancreatitis who were admitted to Department of General Surgery,Taicang First People's Hospital for surgical management from January 2011 to December 2013 were retrospectively analyzed.Patients were divided into early surgery group and delayed surgery group according to the timing.Early surgery group was defined as the patients whose symptoms of pancreatitis were basically disappeared after conservative treatment and surgery was performed within two weeks,while delayed surgery group was defined as the patients who underwent surgery after two weeks.Results Of the 44 acute gallstone pancreatitis cases,18 patients were males,and 26 were females,with median age of 54 years old (range 26-83 years old).Forty-two cases were mild acute pancreatitis and the other two cases were severe acute pancreatitis.Preoperative imaging indicated both cholecystolithiasis and choledocholithiasis in 5 patients,cholecystolithiasis alone in 39 patients.The 5 patients underwent cholecystectomy and choledocholithotomy with T-tube drainage.Among these 5 cases,one patient with concomitant acute suppurative cholangitis had an emergency surgery,two patients with Ranson score ≤3 had early surgery,and two patients with Ranson score ≥4 had delayed surgery,and all the patients were cured and discharged.Thirty-nine cases with cholecystolithiasis alone were treated with laparoscopic cholecystectomy.Among the 39 patients,25 patients underwent early laparoscopic cholecystectomy,and the other 14 patients underwent delayed surgery,and all the patients were cured and discharged.When compared with delayed group,the average age and Ranson score of early group were lower [(46 ± 12) yrs vs (64 ± 11) yrs and (1.0 ± 0.5) vs (1.5 ± 0.8)],and the median hospital length of stay and the cost were significantly less in the early group than those in the delayed group [(14.0 ± 2.8) d vs (18.1 ± 3.3) d and (17 899 ± 3461) Yuan vs (23 710 ± 3230) Yuan],and the difference between the two groups was statistically significant (P＜0.05).Nevertheless,there was no difference between the operation time and recovery time.There was no conversion to open surgery or post-operative complication in the two groups.Conclusions For severe acute pancreatitis,the delayed operation is recommended when the symptom of pancreatitis is completely improved after conservative management,while for mild acute pancreatitis,early surgery does not increase operation difficulty and complication,and it can decrease the length of hospital stays and costs.
