Objective To investigate the related factors of clinical incidence and the ultrasound diagnostic value of endometrial polyps (EMP).Methods A total of 278 patients with clinical abnormal vaginal bleeding,menorrhagia,infertility,cervical polyps or physical examination showing EMP received vaginal ultrasound and hysteroscopy.The related clinical factors were recorded and single factors and multivariate unconditional Logistic regression analysis were carried.Results The univariate analysis showed that the number of pregnancy,menopause,placing intrauterine device,oral comtraceptives,history of hormone therapy,chronic endometritis,cervical polyp,merger endometriosis and obesity were the statistically significant factors of EMP incidence (P ＜ 0.05 or ＜ 0.01),which were used as dependent variables for multivariate Logistic regression analysis,indicating that menopause,chronic endometritis,history of hormone therapy and cervical polyp significantly affecting EMP incidence (P ＜ 0.05),with OR values of 4.068,4.122,3.770 and 3.983 respectively.Conclusion Menopause,chronic endometritis,history of hormone therapy,cervical polyps are the related risk factors of EMP.

Hepatitis B virus (HBV) is a major cause of chronic liver disease, and frequently results in hepatitis, cirrhosis, and ultimately hepatocellular carcinoma. HBV polymerase (Pol) is an essential viral protein that is important for HBV replication and might be involved in the development of hepatocellular carcinoma. Protein-protein interactions appears to be crucial for its role. The aim of this study was to screen and identify the proteins that interact with Pol using a co-immunoprecipitation-based LC-MS/MS identification technique. The HBV Pol gene was amplified by polymerase chain reaction (PCR) and cloned into pCDNA3.1(+). The recombinant plasmid pCDNA3. 1(+)-Pol-flag was transfected into HeLa cells. Liquid chromatography and tandem mass spectrometry (LC-MS/MS) identified 45 proteins that co-immunoprecipitated with flag-tagged HBV Pol. Eleven of these have previously been reported as proteins that interact with HBV Pol. A proof-of-concept-based Ingenuity Pathway Analysis (IPA, www.ingenuity.com) was used to characterize the functions and pathways of these 45 identified proteins and HBV Pol. Among these proteins, four proteins may play a role in three major molecular cellular networks, and are therefore worthy of further investigation.

Objective To investigate the efficacy and toxicity of neoadjuvant chemotherapy of modified FOLFOX7 regimen in the treatment of advanced gastric cancer. Methods The clinical data of 30 patients with advanced gastric cancer who had been admitted to Beijing Friendship Hospital from June 2005 to January 2009 were retrospectively analyzed. All patients received modified FOLFOX7 regimen [oxaliplatin (100 mg/m~2) + fluorouracil (2400 mg/m~2) + calcium folinate (400 mg/m~2)] for 2-4 courses before operation. The efficacy and toxicity of the modified FOLFOX7 were evaluated before and after the operation. All data were analyzed via chi-square test. Results The pre-and postoperative downstaging rates were 27% (8/30) and 47% (14/30), respectively. The total effective rate of modified FOLFOX7 regimen was 43% (13/30). Complete remission was observed in 1 patient. The toxicity was mild. Radical resection was accomplished in 28 patients (93%). There was no statistical difference between the 2 criteria in evaluating the efficacy of modified FOLFOX7 regimen (χ~2= 2.584, P>0.05). Conclusion Modified FOLFOX7 regimen is effective and well-tolerable for patients with advanced gastric cancer.

Objective To evaluate the value of blood coagulation biomarkers in orthopaedic traumatic patients after surgery and analyze its diagnostic values for venous thrombosis embolism.Methods In thiscase control study, we consecutive enrolled 108 traumatic patients after surgery.54 patients have thrombosis and other 54 patients have no thrombosis.Blood was taken 3 -4 days after surgery.Routine coagulation screening test , FDP(fibrinogen/fibrin degradation products) , D dimer and new item such as TM( thrombomodulin) , TAT( thrombin-anti-thrombin complex) , t-PAIC( tissue-type plasminogen activator-plasminogen activator inhibitor complex),PIC(plasmin-anti-plasmin complex) were tested.The difference between groups of these biomarkers was compared, and then the receiver operation curve ( ROC) was drew to determine the diagnostic cut-off point and diagnostic performance.Results ALL blood coagulation biomarkers in orthopaedic traumatic patients after surgery were significantly increased.The group of patients with thrombosis have higher TM(9.04 ±2.06) IU/ml,t-PAIC(10.15 ±4.23) ng/ml, PIC(1.15 ±0.70)μg/ml, D dimer(5.31 ±5.10) ng/ml than group without thrombosis TM(7.50 ±1.70) IU/ml, t-PAIC (6.97 ±2.56)ng/ml, PIC(0.93 ±0.84)μg/ml,D dimer(2.35 ±2.12)ng/ml,and P=0.000 2,<0.000 1,<0.000 1,<0.000 1, respectively.However, TAT(4.79 ±4.32)ng/ml, (6.51 ±5.92)ng/ml, FDP (8.87 ±7.68 )μg/ml, ( 4.91 ±4.67 )μg/ml showed no difference between thrombosis groupand no thrombosis group, (P=0.212 3,0.050 8; respectively).The area under the ROC curve of TM, t-PAIC, PIC and D-dimer were 0.718 5,0.741 6,0.648 0,0.670 0, respectively; P values were <0.000 1,<0.000 1, 0.009 3,0.004 1, respectively; cut-off values were 11.15 IU/ml, 10.65 ng/ml, 1.36 μg/ml, 7.69 ng/ml, respectively;positive likelihood ratios were 9.00,11.29,3.66,14.60, respectively;specificity were 98.15%,96.23%, 90.20%, 97.96%, respectively; the diagnostic rates were 20.3%, 46.3%, 35.8%, 25.9%, respectively.Conclusions There were coagulation and fibrinolysis system activated in orthopaedic traumatic patients after surgery.TM, t-PAIC, PIC, D dimer were good biomarkers for the diagnosis of thrombosis after trauma surgery.TAT was not fit for screening thrombosis after surgery because of influence of anti-coagulation.

This study was carried out to evaluate the anti-inflammatory and free radical scavenging activities of flavans from flex centrochinensis S. Y. Hu in vitro and their structure-activity relationship. LPS-stimulated RAW 264.7 macrophage was used as inflammatory model. MTT assay for cell availability, Griess reaction for nitric oxide (NO) production, the content of TNF-alpha, IL-1beta, IL-6 and PGE, were detected with ELISA kits; DPPH, superoxide anion and hydroxyl free radicals scavenging activities were also investigated. According to the result, all flavans tested exhibited anti-inflammatory effect in different levels. Among them, compounds 1, 3, 4 and 6 showed potent anti-inflammatory effect through the inhibition of NO, TNF-alpha, IL-lp and IL-6, of which 1 was the most effective inhibitor, however, 2 and 5 were relatively weak or inactive. The order of free radical scavenging activities was similar to that of anti-inflammatory activities. Therefore, these results suggest that 3, 4 and 6, especially of 1, were,in part responsible for the anti-inflammatory and free radical scavenging activity of Ilex centrochinensis. Hydroxyl group at 4'-position of B-ring plays an important role in the anti-inflammatory and free radical scavenging capacities.

Objective To explore the role of hydrogen peroxide in mesenteric artery contraction of cirrhotic rats with portal hypertension,which was induced by bile duct ligation.Possible mechanism in RhoA/ROCK signal pathway was also part of the focus.Methods The bile duct ligation-induced cirrhotic rats and normal rats (control group) were treated equally with PEG-catalase(10 000 U/kg-1 · d-1,ip.) or by its vehicle for 8 days.Then the level of H2O2 in mesenteric arteries was detected.The contractile response to norepinephrine of arterioles was analyzed by vascular perfusion system.The protein expressions of the α1 adrenergic receptor,β-arrestin-2 and Rho kinase-1 (ROCK-1),and the activity of ROCK-1 were measured by western blot.In addition,the interaction of α1-adrenergic receptor with β-arrestin-2 was assessed by co-immunoprecipitation.Results Compared to normal rats,the dose-response curve of the mesenteric arterioles in response to norepinephrine shifted to the right,and the EC 50 increased in the rats with portal hypertension.PEG-catalase treatment can decrease the hydrogen peroxide level in arteries,thus significantly lowered EC50 and improved the reactivity to norepinephrine of the mesenteric arterioles in portal hypertension rats.No significant difference in the α1-adrenergic receptor amounts was observed among groups.There was remarkable decreases in the protein expressions of β-arrestin-2 and its interaction with the α1-adrenergic receptor in cirrhotic rats with PEG-catalase treatment.PEG-catalase also increased the amount and activity of ROCK-1 in cirrhotic rats.Conclusions The level of hydrogen peroxide increases in the mesenteric arteries in bile duct ligation-induced cirrhotic rats.And it enhances the β-arrestin-2 expression and its interaction with the α1-adrenergic receptor,which subsequently decreases the amount and activity of ROCK as well as the contractility of mesenteric arteries in response to vasoconstrictors.

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95％ confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84％ (33/3913),0.35％ (14/3985),0.44％(17/3888),0.54％ (21/3909),0.91％ (35/3860) in women (x2 =15.676,P =0.003) and 1.18％(180/15 238),1.26％ (191/15 170),1.11％ (170/15 323),1.45％ (221/15 216),1.82％ (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95％ CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.
