Objective To explore the expression of CD14 and TLR4 ( Toll like receptor - 4) in peripheral blood monocytes during the different stage of cancer patients. Methods The expression of TLR4 and CD14 on peripheral blood monocytes was determined by flow cytometry in 50 healthy control group and 80 patients with malignant tumor who were divided into stable group and advanced group according to the change of the size of tumor measured by image and/or the outcome of tumor makers. Results No significant difference was found in the expression level of CD14 between the different stage of malignant tumor ( stable group and advanced group) and healthy controls [ (6. 1600% ? 2. 32217% ,5. 8629% ? 1. 91896% ) vs (5. 5580% ? 1. 42272% ) ]. The expression of TLR4 in stable group had no significant difference as compared with control group [ ( 10. 4444 ? 3. 16225 ) % vs (8. 8780 ? 5. 24612) % ]. The expression of TLR4 in advanced group was significantly higher than that in controls and stable group [ ( 14. 7286 ? 6. 95213 ) % vs ( (8. 8780 ? 5. 24612) % , ( 10. 4444 ? 3. 16225) % ) (P

BACKGROUND: Lower urinary tract abnormality (LUTA) can lead to end-stage renal disease (ESRD). However, insufficient attention has been paid to these patients in China, and they are usually thought unsuitable for kidney transplantation because of high incidences of graft dysfunction and septic complication.OBJECTIVE: To explore the characteristics and postoperative follow-up after kidney transplantation in four patients with LUTA.DESIGN, TIME AND SETTING: A retrospective analysis of LUTA cases was performed from July 2002 to June 2006 at the Organ Transplantation Center of Chinese PLA, Second Affiliated Hospital of General Hospital of Chinese PLA.PARTICIPANTS: Four ESRD cases of LUTA, who received allograft kidney transplantation.METHODS: Four cases of LUTA experienced detail evaluation before kidney transplantation. Ureter was reimplanted into the original bladder during transplantation and suprapubic cystostomy was performed as urinary drainage.MAIN OUTCOME MEASURES: Patient and graft survival, graft function, urinary tract infection (UTI) and graft rejection were supervised after surgery and quality of life was evaluated.RESULTS: Two patients recovered well with normal renal function and no rejection. Despite the moderate but easily controlled UTI, they handled the urinary diversion well and were satisfied with the quality of life. One patient experienced an acute rejection 17 days after transplantation and survived with functional graft until now after the rejection was reversed. One patient lost the graft for repeated hemorrhage at the site of vascular anastomosis, and then returned to hematodialysis.CONCLUSION: Kidney transplantation is suitable but special for patients with LUTA. Careful evaluation before transplantation, suitable urinary drainage and rigorous follow-up after surgery are keys to the success of kidney transplantation for this subgroup of patients.

Iatrogenic gastrointestinal perforation is one of the severe adverse events of endoscopic therapeutic procedure. For acute iatrogenic perforation,management by endoscopic techniques is a simple and rapid modality to close the perforation with minimal invasiveness and avoiding the traditional surgical trauma. Endoclips,suture with special instruments,covered stents,degradable sheets combined with tissue adhesive,and combined endoscopic techniques such as snares combined with endoclips,are the major endoscopic therapeutic modalities for closure of iatrogenic gastrointestinal perforation. In this article,the current status and progress of endoscopic management for acute iatrogenic gastrointestinal perforation were reviewed.

BACKGROUNDWheat-dependent exercise-induced anaphylaxis (WDEIA) is a complex disease resulting from interaction of environmental and genetic factors. The aim of this study was to investigate the association of three single nucleotide polymorphisms (SNPs) (IL-4-C590T, IL-4RA A1727G and IL-10-A627C) with WDEIA.

METHODSSNP genotyping was conducted among the case subset composing 51 patients with WDEIA and four control subsets by sequencing DNA yielded from polymerase chain reaction (PCR). Statistical analysis of genotype/allele's frequencies between cases and controls were carried out through Fisher's exact test with the software of SPSS16.0.

RESULTSFor IL-4-C590T, there were statistically significant differences of genotype frequencies in case-control 1 (P = 0.03) and case-control 4 (P = 0.001) and statistically significant differences of allele frequencies in three case-control models (case-control 1: OR = 4.27 (95%CI = 1.40 - 13.07), P = 0.009; case-control 3: OR = 1.99 (95%CI = 1.13 - 3.50), P = 0.02; case-control 4: OR = 2.39 (95%CI = 1.49 - 3.84), P = 0.001). All other association studies showed no statistically significant (P > 0.05).

CONCLUSIONSIL-4-C590T may be related to the susceptibility of WDEIA, and the minor allele C might be a potential risk factor accounting for WDEIA. IL-4RA A1727G and IL-10-A627C might not be involved in the occurrence of WDEIA.

ObjectiveTo evaluate and compare the outcomes of missed Monteggia fractures in children treated with ulnar angulation-distraction osteotomy and plate fixation or external fixation.Methods Nineteen patients,including 11 boys and 8 girls who presented with missed Monteggia fracture,were reviewed from July 2005 to June 2011.Twelve children (Group A) were treated with ulna angulation osteotomy and plate fixation,and 7 eases(Group B) with ulna angulation-distraction osteotomy and external fixator.Thirteen patients were classified as type Bado Ⅰ,and six as type Bado Ⅲ.The age,the delay from injury to surgery,complications,elbow and forearm function,and the healing time of the osteotomy were compared.ResultsAll 19 patients were followed up.The duration of missed dislocation was from 6 to 36 months (mean,10 months).Redislocation of the radiocapitellar joint occurred after surgery in one case in group A.Forearm compartment syndrome occurred in one case after surgery in group B.All patients,except one,regained full elbow flexion in group A and B,various forearm pronation limitation were noted in all patients (mean,15°).The average healing of osteotomy of group A and B was 8 weeks(6-15 weeks) and 22 weeks (10-44 weeks).ConclusionThe ulnar angulation-distraction osteotomy could correct the ulnar deformity in children of missed Monteggia fractures,which is the key issue to be corrected.Both of the fixation strategies can obtain the same treatment results.Preoperative assessment is most important,plate internal fixation was recommended for young age and short delay cases,on the contrary,we prefer to choose external fixator.

Objective To investigate the effects of lipopolysaccharide(LPS) on the tryptophan-kynurenine(TRP) metabolic pathway in rat brains and provide new evidence for the relationship between inflammation and depression.Methods Rats in LPS group were given a single dose of 3.5 mg/kg LPS.while the rats in control group were given the same dosage of saline.The dialysis in ventro-hippocampus were collected by microdialysis within 8 hours and then the TRP,KYN and KA were detected by LC-MS/MS.And the expression of indoleamine 2,3-dioxygenase was detected by Western-blot.Results The level of TRP((550.15± 107.96) pmol/L) and KYN ((337.95±62.73) pmol/L) showed a time-dependent increase after administration LPS 4 h compared with the control group(TRP (368.38±59.31) pmol/L,KYN (172.80±43.96) pmol/L),while KA level in the circulation exhibited a trend to decrease,especially at 7 h ((3.47±0.62) pmol/L,P＜0.05).The ratio of KYN/TRP significantly increased at about 5 h (0.69±0.11,P＜ 0.05),and an ratio of KA/KYN (0.02±0.00) was dramatically decreased after administering LPS 4 h compared with the control group (0.05±0.01)(P＜0.05).Most of the analytes showed more dramatic changes around 4 h to 8 h.LPS group(1.48±0.37) increased the protein expression of indoleamine 2,3-dioxygenase compared with the control group(1.00±0.24) (P＜0.01).Conclusions LPS may cause tryptophan metabolic abnormalities and accelerate the way of kynurenine metabolism,leading to decreased the kynurenic acid status.

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.

Objective · To investigate the smoking hypertensive elderly, find out the status of smoking in this population, and explore effective system intervention. Methods · The smoking hypertensive elderly in Waigang Town of Shanghai who received free antihypertensive drugs were recruited to investigate and descriptively analyze the smoking status of them with questionnaires. Results · There were 77.6% of the smoking hypertensive elderly who began to smoke in the age of 13 to 25, and nearly 70% smoking for more than 40 years. There were 59.5% of these people smoking 11 to 29 cigarettes daily in recent 3 years, and 41.6% spending 200-299 yuan on smoking monthly. Conclusion · Currently almost 70% of the smoking hypertensive elderly, who receives free antihypertensive drugs, have been smoking for more than 40 years, and the average number of cigarettes smoked daily is big. It is clear that the health education attached to the policy of providing free antihypertensive drugs has not changed the behavior. Therefore, medical personnel still needs to contact the illness and smoking hazards to help the elderly reduce smoking. Besides, it proves that tobacco control should be implemented in the young population to control epidemic at the early stage.

Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.
