BACKGROUNDMumps virus infection is a potentially serious viral infection of childhood and early adulthood. In China, live attenuated S(79) mumps vaccine has been licensed for pediatric use since 1990. The objective of this study was to determine the effectiveness of live attenuated S(79) mumps vaccine against clinical mumps in outbreaks.

METHODSCases were selected from mumps outbreaks in schools in Guangzhou between 2004 and 2005. Each case was matched by gender, age and classroom. Vaccination information was obtained from Children's EPI Administrative Computerized System. Vaccine effectiveness (VE) was calculated for 1 or 2 doses of S(79) vaccine with 95% confidence intervals (CI).

RESULTSOne hundred and ninety-four cases and 194 controls were enrolled into the study. VE of the S(79) mumps vaccine for 1 dose versus 0 confer protection 80.4% (95% CI, 60.0%-90.4%) and VEs against mumps in outbreaks for 1 dose of mumps vaccine are similar among those children aged 4-9 years and aged over 10 years old.

CONCLUSIONThe live attenuated S(79) mumps vaccine can be effective in preventing clinical mumps outbreaks.

Objective　To evaluate the therapeutic effect of rapid angulation rotation traction for lumbar intervertebral disc protrusion. Methods　A total of 88 patients (66 male and 22 female;age: 18-65), with a history of 2 days to 10 years were analyzed. Among them 20 cases were central protrusion 68 cases were lateral protrusion. Traction range: 60-65 mm, angle: 20°-25°, rotation degree: 20°-25°, traction time: 3 s-1 min. The process of treatment was computer designed. The traction was then 1 to 3 times, with a interval of 4-7 days between two treatments. Results　The effective rate was 96% for the case with history <1 month 96% and 85% for cases with history >1 month (P<0.01). The effective rate was 62% for central protrusion, and 87% for lateral protrusion respectively. χ2 test showed the difference was not significant. Conclusion　The rapid angulation rotation is an effective treatment for lumbar inter-vertebral disc protrusion and this non operative method should be used as early as possible.

BACKGROUNDNeoadjuvant chemoradiation is now considered the standard care for locally advanced rectal carcinoma (T3-4 or/and N1-2 lesions), but the accuracy of staging examinations including endorectal ultrasonography (ERUS) and MRI is far from excellent. In addition, the above staging equipment or professionals who perform the examinations may not be available in some hospitals, while preoperative colonoscopy and biopsy are usually obtainable in most hospitals. The objective of the present study was to investigate the clinical and pathological characteristics of locally advanced rectal carcinoma and identify candidates for neoadjuvant chemoradiation.

METHODSThis was a retrospective study. Patients who were treated for rectal cancer at Changhai Hospital from January 1999 to July 2008 were identified from our prospectively collected database. Statistical analysis was performed using SPSS Software System (version 15.0). The Mann-Whitney test, chi-square test and multivariate Logistic regression analysis were performed.

RESULTSA total of 1005 cases were included in this research, of which 761 cases were identified as locally advanced rectal carcinoma depending on postoperative TNM staging. The results of multivariate Logistic regression analysis indicated seven independent risk factors that could be used to predict a locally advanced rectal carcinoma independently: a high grade (including poor differentiation and undifferentiation) (OR: 3.856; 95% CI: 2.064 to 7.204; P = 0.000); large tumor size (OR: 2.455; 95% CI: 1.755 to 3.436; P = 0.000); elevated preoperative serum CEA level (OR: 1.823; 95% CI: 1.309 to 2.537; P = 0.000); non-polypoid tumor type (OR: 1.758; 95% CI: 1.273 to 2.427; P = 0.001); the absence of synchronous polyps (OR: 1.602; 95% CI: 1.103 to 2.327; P = 0.013); the absence of blood in stool (OR: 1.659; 95% CI: 1.049 to 2.624; P = 0.030); and a greater circumferential tumor extent (OR: 1.813; 95% CI: 1.055 to 3.113; P = 0.031). Based on these findings, a Logistic equation was established, the accuracy of which was 64% according to the information of the additional 50 cases.

CONCLUSIONSSome independent risk factors related with locally advanced rectal carcinoma were identified, based on which it is possible to establish a Logistic equation as a tool to predict candidates of neoadjuvant chemoradiation. Further research about optimization of the equation is warranted.

Objective To summarize the experience of long-term survival in patients after simulta- neous kidney-pancreas transplantation(SKPT)with modified enteric drainage(ED).Methods From October 2001 to July 2004,6 patients with end-stage renal disease due to Type 1 diabetes underwent SKPT with modified ED,ie,side-to-side anastomosis between the duodenum of donors and jejunum of recipients. The medication regimen included:mycophenolic acid 500 mg and tacrolimus 2 mg before operation;methyl- prednisolone(MP)1.0 during operation;and 2-dose anti-IL-2 receptor monoclonal antibody(2 cases)or antihuman thymocyte globulin(ATG)(4 cases)for immune induction therapy;MP was used on the first 3 d after transplantation,triple immunosuppressive therapy(tacrotimus,mycophenolic acid and prednisone)was used on the second d after transplantation.Anticoagulants such as low molecular heparin or alprostadil were used for 7-10 d to prevent thrombosis in pancreas graft.Somatostatin was used as prophylaxis for graft pan- creatitis.Ganciclovir was used to prevent cytomegalovirus infection when renal graft gradually recovered 3 to 5 d after transplantation.The follow-up was from 1 year and 3 months to 4 years and 1 month.Results Transplantation was successful in all 6 cases.The blood sugar levels were 6-16 mmol/L.Low-dose insulin was used for 5-10 d,then the blood sugar levels returned to normal range.One of 6 patients experienced nephrotoxicity because of high tacrolimus blood concentration at 7 d after operation;after 3 dialyses and re- duction of tacrolimus dose,the renal allograft regained normal function.Three cases experienced alimentary tract hemorrhage at 14,20 and 22 d,respectively,after operation;the bleeding was stopped after treatment. There were no complications such as pancreatic fistula,intestinal fistula and thrombosis early after operation. All the patients are now alive,specifically,1 survived over 4 years,3 over 3 years,1 over 2 years,and 1 over 1 year.All had normal blood sugar free of insulin use.Five cases had normal renal graft function,with normal sCr,and 1 had sCr＞400?mol/L. Two cases were admitted to hospital due to upper respiratory infection and furuncles in the skin of head 6 months and 2 years,respectively,after operation.They were both cured.No complications such as urinary infection,metabolic acidosis and dehydration occurred.Conclusions SKPT is effective for the treatment of end-stage renal disease due to Type 1 diabetes.SKPT with modified ED are relatively simple with physiological compatibility and fewer complications.High quality of donated organs, HLA matching,pancreatic drainage pattern,rational periopcrative medications and infection late after trans- plantation are important factors affecting the long-term survival of the patients.

OBJECTIVETo compare the accuracy of preoperative assessment in differentiation and grading of rectal adenocarcinoma.

METHODSOne hundred consecutive patients diagnosed as invasive rectal cancer by colonoscopy biopsy and undergone operation in the Changhai Hospital from March 2006 to May 2008 were studied retrospectively. Patient characteristics, examination records, operative and pathologic reports were reviewed. The slides of preoperative biopsy and postoperative pathologic specimen were reviewed to identify the differentiation by a single pathologist. The results of preoperative biopsy were compared to those of postoperative specimen which was considered as final diagnosis. The accuracy of preoperative assessment of differentiation was calculated. Patients were then divided into two groups based on the preoperative differentiation:the low-grade tumor including well and moderately differentiated tumors, and the high-grade tumor consisting of poorly differentiated and undifferentiated tumors. The accuracy of grading was also calculated.

RESULTSThe accuracy of preoperative assessment of differentiation was 72%, with 20% overgrading and 8% undergrading, while the accuracy of preoperative grading was 91%, with 4% overgrading and 5% undergrading. The accuracy of grading was significantly higher than that of specific differentiation(P<0.01).

CONCLUSIONThe grading of preoperative biopsy has high accuracy rate and should be considered in clinical practice.

OBJECTIVETo evaluate the effect of computer assisted navigation system in the treatment of unilateral zygomatic complex fractures.

METHODSFive patients with unilateral zygomatic complex fractures were included in this study.Preoperative design, intraoperative real-time navigation and postoperative evaluation with chromatogram were executed in the unaffected and affected side.

RESULTSUsing computer assisted navigation system, the position and direction of the affected side of the unilateral zygomatic complex fracture were confirmed and shown real-time on the screen. The global maximal deviation was less than 2 mm between the affected side and the mirror side of the healthy side with chromatogram.

CONCLUSIONSComputer assisted navigation system can instruct the treatment of unilateral zygomatic complex fractures effectively. The global comparison with chromatogram is more objective for the unilateral zygomatic complex fractures.

BACKGROUNDCerebral venous thrombosis (CVT) may lead to serious neurological disorders; however, little is known about the risk factors for recurrent CVT. Our aim was to determine the association between elevated fibrinogen and decreased high-density lipoprotein cholesterol (HDL-C) levels with recurrent CVT.

METHODSThis retrospective cohort study included participants if they had a first episode of objectively defined CVT and were admitted to Xuan Wu Hospital, Capital Medical University from August 2005 to September 2009. Demographic and clinical variables were collected, as well as laboratory parameters, including plasma fibrinogen and HDL-C. Patients with CVT were followed for recurrent symptomatic CVT. Follow-up was through the end of September 2010. Potential predictors of recurrence were analyzed using Cox survival analysis.

RESULTSAt the end of the follow-up, 95 patients were eligible for the study. Twelve of 95 patients (12.6%) had recurred CVT. The median time of recurrence was 7 months (range: 1-39 months). Eight of these 12 (66.7%) experienced recurrence within the first 12 months after their initial CVT. The recurrence rate of CVT was 2.76 per 100 patient-years. Multivariate Cox regression analysis demonstrated that the coexistence of high fibrinogen (>4.00 g/L) and low HDL-C (<1.08 mmol/L) levels at baseline was the only independent predictor for recurrent CVT (hazard ratio: 4.69; 95% confidence interval: 1.10-20.11; P < 0.05). Of the twelve patients with recurrent CVT in our study, 7 (58.3%) had high fibrinogen plus low HDL-C levels. All 7 of these patients took warfarin for 3-12 months, and 6 of 7 had recurrent CVT after the discontinuation of anticoagulant treatment.

CONCLUSIONSConcomitant high fibrinogen and low HDL-C levels may be associated with recurrence of CVT. The effect of potential risk factors related to atherothrombosis on recurrent CVT should be closely monitored.

This study examined the expressions of miR-22 and miR-135a in rats with acute edematous pancreatitis (AEP) and their target genes in order to shed light on the involvement of miR-22 and miR-135a in the pathogenesis of acute pancreatitis (AP). The in vivo model of AEP was established by introperitoneal injection of L-arginine (150 mg/kg) in rats. The miRNA microarray analysis was used to detect the differential expression of miRNAs in pancreatic tissue in AEP and normal rats. The in vitro AEP model was established by inducing the rat pancreatic acinar cell line (AR42J) with 50 ng/mL recombinant rat TNF-α. Real-time quantitative RT-PCR was employed to detect the expression of miR-22 and miR-135a in AR42J cells. Lentiviruses carrying the miRNA mimic and anti-miRNA oligonucleotide (AMO) of miR-22 and miR-135a were transfected into the AR42J cells. The AR42J cells transfected with vehicle served as control. Western blotting was used to measure the expression of activated caspase3 and flow cytometry analysis to detect the apoptosis of AR42J cells. Targets of miR-22 and miR-135a were predicted by using TargetScan, miRanda, and TarBase. Luciferase reporter assay and quantitative real-time RT-PCR were performed to confirm whether ErbB3 and Ptk2 were the target gene of miR-22 and miR-135a, respectively. The results showed that the expression levels of miR-22 and miR-135a were obviously increased in AEP group compared with the control group in in-vivo and in-vitro models. The expression levels of miR-22 and miR-135a were elevated conspicuously and the expression levels of their target genes were reduced significantly in AR42J cells transfected with lentiviruses carrying the miRNA mimic. The apoptosis rate was much higher in the TNF-α-induced cells than in non-treated cells. The AR42J cells transfected with miRNA AMOs expressed lower level of miR-22 and miR-135a and had lower apoptosis rate, but the expression levels of ErbB3 and Ptk2 were increased obviously. It was concluded that the expression levels of miR-22 and miR-135a were elevated in AEP. Up-regulating the expression of miR-22 and miR-135a may promote the apoptosis of pancreatic acinar cells by repressing ErbB3 and Ptk2 expression in AEP.

Background Since the measurement method establishment of serum ferritin abroad in early period of theseventies, the iron deficiency had been divided into two types: the non-anemia and anemia types. In orderto go step further studies, we must ertablish the bemoglobin targets of the two types. Methods One hurdred and fifty-two children in experimontal group, from 6 to 7 years old, and allcome from Qinghai province. There are 29 children in Xining city, 24 in Guide, 26 in Gongbe, 40 in Gui-nan and 33 in Maduo countics. There are 36 health children aged from 6 to 7 years old in the controlgroup, and all comes from Beijing. The Hb, RBC, HCT, HCTW and FEP wcre determined. Results The three targets correlating with Hb (Hb, MCH and MCHC); correlating with RBC (RBC,HCT and MCV); the two targets correlating with RBC_weight (HCTW and CMCW) and correlating withFEP of RBC(FEP and MCEP) have very significant difference between experimental group and control group. Conclusion The determination values of the 10 targets are not same in children in different districts,and the values of all the target: are increased on different degree along with the increase in altitude of ele-vation. There is very important significance on the studies of iron deficiency and altitude hypoxia to establish the normal values of the 10 targets.
