ObjectiveTo investigate the high risk factors,etiology,diagnosis,treatment and precaution of venous thromboembolism (VTE) in pregnancy and puerperium. MethodsData of 16 cases of VTE admitted in Department of Obstetrics and Gynecology,Peking Union Medical College Hospital from January 1992 to April 2011 were analyzed retrospectively.The differences of blood routine test and coagulation function between VTE patients (study group) and normal pregnant women (control group) were compared by paired t test in this case-control study.Results All patients were diagnosed by color Doppler ultrasound or CT pulmonary artery angiography.Five cases (31.2 ％) occurred before delivery and 11 (68.8 ％) occurred during postpartum.Two cases (12.5 ％)complicated by pulmonary thromboembolism,and one of them died.Six cases (37.5％) were older than or equal to 35 years old,and 12 cases (75.0％) had gestational complications.The hematocrit in study group were lower than that in control group (0.29±0.06 vs 0.39±0.02,t=4.56,P=0.01).There was no statistical difference between the coagulation function of the two groups.After anticoagulant therapy or surgery,15 cases recovered.One pulmonary thromboembolism patients complicated with rheumatic cardiac disease remained shock after anti-coagulants was administered,then died of hemorrhage of respiratory tract after inferior vena cava filter placement. Conclusions VTE is likcly to happen in puerperium than in pregnancy.There are no good screening indicators for thromboembolism during pregnancy and puerperium.Anticoagulation is recommended to be the first line therapy.For women with high risk of thromboembolism,it is suggested to prevent actively and treat early to decrease the complications and long-term sequelea.

Objective To investigate the effects of H. pylori infection on cyclooxygenase 2 (COX 2) expression in gastric antral mucosa. Methods Antral biopsies were taken from 46 patients with chronic gastritis and H. pylori infection before and after anti H. pylori treatment. COX 2 protein was stained by immunohistochemical method. Gastritis and H. pylori infection status were graded according to the updated. Sydney system. Results Cytoplasmic staining of COX 2 protein could be detected in epithelial cell both before and after eradication of H. pylori . The mean percentage of the cells staining with COX 2 was significantly higher in H. pylori infected mucosa, compared with the mucosa after successful H. pylori eradication [(20.1?13.1)% vs (13.8?5.9)%, P

OBJECTIVE:To explore the effects of alendronate sodium on bone mineral density (BMD) and bone marker in prostate cancer elderly patients after medical castration therapy. METHODS:In perspective study,84 elderly patients undergoing medical castration therapy were selected and divided into treatment group(45 cases)and control group(39 cases)according to ran-dom number table. Control group received medical castration therapy+Calcium carbonate D3 tablets,1 tablet,po,qn;treatment group was additionally given Alendronate sodium tablets 70 mg,po,once a week,1 week after routine treatment,on the basis of control group. Treatment course of 2 groups lasted for 12 months. The levels of 25-OH-D,testosterone,BMD and bone marker were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:3 cases of treatment group and 1 case of control group dropped out of the study. Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,25-OH-D levels of 2 groups were increased slightly,but there was no statistical significance(P>0.05);tes-tosterone level of 2 groups were decreased significantly compared to before treatment,with statistical significance (P<0.05). 12 months after treatment,BMD of lumbar vertebra,collum femoris and hip were increased significantly in treatment group,while those were decreased significantly in control group;there was statistical significance in above indexes between 2 groups(P<0.05). The levels of N-terminal midfragment of osteocalcin,procollagen Ⅰ N-terminal propeptide and β-crosslaps were decreased signifi-cantly in treatment group,while those were increased significantly in control group;there was statistical significance in above in-dexes between 2 groups (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Alendronate sodium can prevent bone loss and reduce the rate of bone turnover in elderly patients with prostate cancer receiving medical castration therapy.

A total of 185 patients with type 2 diabetes mellitus (T2DM) were consisted of male group (n =95) and postmenopausal female group (n =90).The parameters of fasting plasma glucose,HbA1c,fasting insulin,fasting C peptide,homeostasis model assessment insulin resistant index (HOMA-IR) and β-cell function (HOMA-β),blood lipid,body mass index,and waist to hip ratio were collected and analyzed by Pearson correlation analysis and stepwise multiple regression analysis.The relationships between osteocalcin and these parameters were investigated.The results revealed that osteocalcin was negatively correlated with HbA1C (P＜0.05),and osteocalcin was an independent relevant factor affecting HbA1Clevels.Osteocalcin may be involved in the regulation of glucose metabolism in T2DM.

Objective To investigate the effect of carteolol hydrochloride eye drops on 24-hour variation of intraocular pressure (IOP). Methods The 30 patients who had never used any anti-glaucoma eye drops were chosen, and their 24-hour variation of IOP (at 2:00 AM, 6:00 AM, 10:00 AM, 2:00 PM, 6:00 PM, 10:00 PM) were measured. Then carteolol hydrochloride eye drops were used twice a day (7:00 AM and 7:00 PM), 1-2 drops each time. Fifteen days later, their 24-h IOP was measured again and the data were analyzed. Results The average IOP at six monitoring points before treatment were (19.77±2.51) mm Hg, (19.52±2.34) mm Hg, (20.38±2.71) mm Hg, (20.07±3.65) mm Hg, (19.97±4.10) mm Hg and (19.97±4.31) mm Hg, the corresponding data after 15 days of treatment were (17.12±2.38) mm Hg, (17.42±2.60) mm Hg, (18.18±2.36) mm Hg, (18.02±3.77) mm Hg, (17.72±3.17) mm Hg and (17.35±3.40) mm Hg (t=11.68, P=0.000). The difference before and after treatment was (2.46±2.05) mm Hg during day and (2.17±1.88) mm Hg during night, and no significant difference was found between them. Conclusions Carteolol hydrochloride eye drops could significantly reduce the IOP, the decreased extent of 24-h IOP is stable.

ObjectiveTo investigate the clinical features and pregnant outcomes of the pregnant women with congenital adrenal hyperplasia (CAH) 21-hydroxylase deficiency (21-OHD).MethodsThe clinical features,therapies,pregnant outcomes of the pregnant women with 21-OHD were retrospectively reviewed in Peking Union Medical College Hospital,from January 2005 to April 2011.ResultsThere were 8 pregnant womenwith 21-OHD including 5siinplevirilizing patientsand 3nonclassical 21-OHD women.Eightpatientswereacceptedprogestationalandprenatalcontinuallowerglucocorticoid treatment.During the gestational period,the dosage of glucocorticoid was adjusted in one pregnancy.The serum level of 17-alpha hydroxyprogesterone (17-OHP) were elevated after pregnancy [ (70 ± 38 ) versus (24 ±23) nmol/L,P ＜ 0.05].The fertility and offspring rate of 8 patients was 8/12,the fertility and offspring rate of patients who started treatment at preadolescence was significantly increased (4/5 versus 4/7).Four patients were accepted genital reconstructive surgery ( clitorectomy,clitoroplasty,vulvoplasty) before pregnancy.The incidence of GDM was 1/8.All patients selected caesarean at from 37 +6 gestation weeks to 39+6 gestation weeks.The average newborn birth weight was (3210 ± 447 ) g,and height was (48 ±2) cm of 8 neonates,none of them was CAH.Conclusions Medical and surgical therapy provides satisfactory fertility and pregnancy outcomes for women with 21-OHD.It is safe to pregnant women with 21-OHD and their fetus in continual lower glucocorticoid treatment.The dosage of glucocorticoid should be carefully adjusted during the pregnancy individually according to serum level of 17-OHP.

Objective To compare the efficacy of pantoprazoh based short-term quadruple regimens in the treatment of Helicobacter pylori (H. Pylori) infection for 4 days,5 days or 7days. Methods 166 patients with H. Pylori associated severe gastritis were randomly divided into pantoprozole quadruple regimens of 4-day group (n =61) ,5-day group (n = 54) or 7-day group (n = 51). The regimen was pantoprazole 40 mg,bismuth potassium citrate 220 mg,elarithromycin 250 mg and amoxicillin 1 g twice daily. The patients received pantoprazole for 1 week, bismuth potassium citrate for 2 weeks,clarithromycin and amoxicillin for 4 days,5 days or 7 days respectively. The H. Pylori eradication and symptomatic relief was determinded by 13C-UBT at least 4 weeks after the therapy. Results The H. Pylori eradication rates of 4-day,5-day or 7-day panteprazole quadruple regimens were 73.8% (45/61) ,75.9% (41/54) and 80.4% (41/51) respectively. The pain relief rates were 82.4% (42/51) ,85.1% (40/47) and 88.9% (40/45) in 4-day,5-day and 7 day group. Conclusion The 4-day and 5- day pantoprazoh based quadrual therapy is a short- term, effective, safe and lower therapeutic- cost regimen for H. Pylori eradication.

By using the high resolution mass spectrometer TripleTOF 5600 , three kinds of standard proteins including bovine serum albumin ( BSA) , ovalbumin ( OVA) and lysozyme C( LYZC) were analyzed, and the correlationship between the ion intensity of mass spectrometry and the relative content of protein sample was investigated. The protein samples were digested by trypsion and diluted to 1-1024 fmol in 7 μL. The ion counts per second ( cps) were used to stand for the amounts of proteins and peptides. Then the correlation between sum of ion intensity ( cps) of all the peptides, number of peptides detected and the amount of proteins was investigated. By comparing the change of values of the same sample in three parallel experiments, a linear relationship between these indexes and the amount of proteins within 1-1024 fmol was found when the cps was more than 1000. Usually, the maximal ion intensity was no more than 1. 5 times of the minimum value for same peptide in triplicate experiments, which suggested that the 3 times or more change of ion intensity was the minimum threshold to determine the differences of proteins amounts in different samples. This study provides a relative quantitative analysis method using qualitative data of high resolution and high scan speed mass spectrometry, which can quickly and easily provide reference for biological and medical research.

Because of the particularity and the complexity of integrated management of food, government regulators must perform the whole process of quality control and trace to evaluate and judge the merits of food instead of only depending on product standards.Quality metrics is a new concept for the food industry, and can be regarded as the comprehensive evaluation and measurement for product quality and the standard for judging the quality of food products.Request for Quality Metrics Guidance for Industry was issued, which not only established a new model for the quality control of pharmaceutical industry, but also provided a new way of quality management for the inspection organization.By introducing the contents of Request for Quality Metrics Guidance for Industry issued by the US FDA, on the basis of summarization and thought, the quality management and evaluation of pharmaceutical industry was compared, and the feasibility and applicability of quality metrics management in inspection and testing field, especially in food testing field was evaluated.In this paper, the concept of quality metrics was extended to the level of food inspection laboratory management with hope to provide ideas for the future development of food quality management model.
