Objective To explore the significance of changes of matrix metalloproteinase-9 (MMP-9),interleukin-6 (IL-6),and tumor necrosis factor-alpha (TNF-oα) protein level in the cerebrospinal fluid (CSF) of children with viral encephalitis (VE).Methods The concentration of neuron-specific enolase (NSE),structural proteins 100B (S100B),and MMP-9,IL-6,TNF-α in the CSF of VE children were detected by an enzyme linked immunosorbent assay,and the correlations of them were analyzed.Results NSE,S100B,MMP-9,IL-6,TNF-α protein expression could be found significantly higher than those in the control group,and there were significant differences according to statistics expression trends(all P ＜0.05).The NSE protein expression was significantly positive related with S100B in the VE group (r =0.467,P =0.009),and the concentration was markedly negative related with the duration of viral encephalitis (r =-0.472,P =0.008).MMP-9,IL-6 protein expression were significantly positive related with NSE,S100B respectively (r =0.698,P =0.00 ; r =0.559,P =0.00 ; r =0.812,P =0.00 ; r =0.664,P =0.00).TNF-α protein expression was positive related with CSF S100B(r =0.363,P =0.049),but there was no correlation between TNF-α and NSE (r =0.245,P =0.193).Conclusions The neurons and the neuroglial cells are damaged in the viral encephalitis children.MMP-9,IL-6,TNF-α protein may participate in the pathological damage process of nerve cells in VE children in different degrees.

Objective To observe and compare the clinical characteristics of colorectal related multiple primary carcinoma (MPC) and colorectal carcinoma (CRC) for promoting early diagnosis and treatment of colorectal related MPC. Methods Pathological and clinical documents of clearly staged CRC and colorectal related MPC cases from Jul. 1997 to Nov. 2007 were retrospectively analyzed. Results 573 colorectal carcinoma cases were analyzed, including 45 MPC (7.85 %). Parenteral multiple carcinoma originated most frequently from stomach, and then breast, ovary, lung, small intestine and other sites. Among all multiple primary colorectal carcinomas (MPCC), ascending colon carcinoma was most frequent (34.0 %).While among CRC cases, rectal cancer cases was most frequent(36.5 %). Comparing CRC and MPCC, there were no significant difference in terms of tumor family history. Median morbidity age was 57 years and 63 years respectively. Cases with previous colonic polyps accounted for 20.0 % of all MPC cases, while only 0.9 % of all CRC cases. The mOS of CRC and MPC was 93.7 month and 64.8 month respectively. Most frequent pathological type of CRC and MPC were both well-moderately differentiated adenocarcinoma, but more mucinous adenocarcinoma cases were observed in MPC. Conclusion Colorectal related MPC are relatively common among colorectal carcinoma patients. More patients with MPC especially MPCC has colonic polyp. mOS of MPC is shorter than that of CRC, indicating the poor prognosis of MPC compared with CRC.MPCC has multiple colonic polyps, shorter interval of secondary carcinomas, and shorter mOS, worse prognosis than MPC with parenteral tumor.

Objective To evaluate the repot of common hepatic duct defect caused by Type Ⅱ or Type Ⅲ Mirizzi syndrome laparoscopically.Methods Eight cases of Type Ⅱ or Type Ⅲ Mirizzi syndrome treated under laparoscopy were analyzed retrospectively.Among them six cases were identified as Mirizzi Ⅱ and a defect on the lateral wall of common hepatic duct was found and repmred by suturing the stubble of cystic duct.The two Mirizzi Ⅲ cases had a defect on front and lateral wall or back and lateral wall of common hepatic duct respectively.Both defects were repaired by a patch from the infundibulum of galllbladder. Results All the 8 cases underwent laparoscopic subtotal cholecystectomy followed by repair of common hepatic duct defect.The operation lasted for 80～150 min(mean 110 min).There was no recurrence of the symptoms after 6～24 months follow up.Conclusion The familiarity of the anatomical characters of Mirizzi syndrome and the skillful suture technique under laparoscopy are both necessary.

Objective:Influence of clinicopathological characteristics and different therapy patterns on the overall survival of patients with gastric cancer with bone metastasis was investigated. Methods:A total of 146 gastric cancer patients with bone metastasis were enrolled from December 1996 to December 2014. Data of clinicopathological characteristics, treatment methods, and overall survival were collected. Univariate and multivariate analyses were performed using log-rank tests and Cox's proportional hazard model, respec-tively. Results:A total of 51 (34.9%) patients had synchronous metastasis, while 95 (65.1%) had metachronous metastasis. Moreover, 35 (24.0%) patients only had bone metastasis, while 111 (76.0%) patients were complicated with other organ metastases, such as liver (30.0%), peritoneal (24.0%), lung (15.1%), and bone marrow (7.5%). After diagnosis of bone metastasis, bisphosphonates, bone radio-therapy and bone surgery were applied in 99 (67.8%), 34 (23.3%), and 5 (3.4%) patients, respectively. Additionally, 96 (65.6%) patients received palliative chemotherapy. The median overall survival was 5.8 months (95%CI:4.284-7.316). Multivariate analysis revealed that KPS<80 (P=0.030), bone marrow metastasis (P<0.001), elevated serum CA199 (P<0.001), and without palliative chemotherapy (P<0.001) were independent poor prognostic factors. Conclusion:The outcome of gastric cancer with bone metastasis is very poor, espe-cially in patients with bone marrow metastasis, worse KPS, and elevated CA199. Palliative chemotherapy may be beneficial for the sur-vival of these patients.

Chronic prostatitis is a highly prevalent disease of unclear etiology. Researches show that autoimmune reaction is one cause of the problem. An effective animal model may help a lot to understand the pathogenesis and find proper diagnostic and therapeutic strategies of the disease. Currently used autoimmune prostatitis-related animal models include those of age-dependent spontaneous prostatitis, autoimmune regulator-dependent spontaneous prostatitis, self antigen-induced prostatitis, and steroid-induced prostatitis. Whether an animal model of autoimmune prostatitis is successfully established can be evaluated mainly from the five aspects: histology, morphology, specific antigens, inflammatory factors, and pain intensity.

Objective To explore the relationship between the serum level of E-selectin and S128R polymorphisms in the exon 4 of E-selectin gene and acute myocardial infarction (AMI) in local Han peoples. Method The genotype of E-selectin were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 168 patients with acute myocardial infarction and 200 healthy controls,and the serum level of E-selectin was measured by enzyme-linked immunosorbent assay (ELISA).Results There was significant difference in frequencies of allele and genotype in S128R polymorphism between acute myocardial infarction and control groups respectively,The relative risk suffered from acute myocardial infarction of SS genotype was 2.234 times of the SR genotype (OR=2.234,95% CI:1.112～4.437),The serum E-selectin level was significantly higher among carriers of SR genotype as compared with SS genotype (41.65?8.87)?g/L vs (34.23?6.72)?g/L,P
