Objective To evaluate the relationship of the hepatocyte growth factor (HGF) and the nuclear matrix protein 22 (NMP22) in urine and the stage and grade of bladder uroepithelium carcinoma.Methods A total of 48 post-operative patients (males 39, females 9) with bladder cancer enrolled in this study were perfused with THP. The voided urine of all the patients before and 6 months after perfusion were recovered selectively. HGF and NMP22 ELISA kits were used to detect bladder cancer. Results The recurrence rate was 12.5 %. The HGF level had positive correlation with the stage and grade of bladder uroepithelium carcinoma (P ＜0.05). The NMP22 level had positive correlation with the grade of bladder cancer. The sensitivity and specificity of HGF, NMP22 and cytology were 100 % (6/6), 83.3 % (5/6), 66.7 %(4/6) and 61.9 % (26/42), 57.1% (24/42), 97.6 % (41/42), respectively. Conclusion The HGF and NMP22 are both valuable tumor markers in the urine of bladder uroepithelium carcinoma. They have intimate relation with the stage and grade of bladder uroepithelium carcinoma. Hence combined with cytology, they could be selected as the significance level of early screening and diagnosing.

Objective To evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free repair of inguinal hernia. Methods A randomized, prospective double-blind control trial was performed to evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free mesh repair in 180 cases of inguinal hernia from March 2007 to March 2008. Intravenous cefuroxime ( 1.5 g ) was given immediately before the surgery in two groups followed by postoperative administration of cefuroxime 1.5 g twice a day for 3 days in test group compared with NS infusion in the control group. Postoperatively 16 patients (8. 89 per cent) could not be contacted at any point, giving a response rate of91. 11%. The total number of subjects for per- protocol (PP) analysis was 180, 84 cases in test group and 80 cases in control group. Results Complete data were available for 164 patients, 3 ( 1.83 per cent) developed surgical site infection (SSI) including 2 cases of surgical site infection in test group and 1 case of superficial incision surgical site infection in control group. The differences were not statistically significant. The time to follow up was 12 -29 months, the mean follow up time in test group was (15.6 ±2.2) months and (18 ±3)months in control group respectively. 93.33% patients in test group were followed up and 88. 89% patients in control group. There were not hernia recurrence and side effect of antibiotics reported in the two groups.Conclusions To prevent SSI, it is necessary to use preoperative antibiotics prophylaxis just one time for inguinal hernia repair.

Objective To study the relationship of soluble LAIR (sCD305 and CD3060) expression in recipient serum with cytomegalovirus (CMV) pneumonitis after renal transplantation. Methods Nineteen serum specimens from recipients were divided into CMV pneumonitis group (n=10) and control group (n=9). Then the concentrations of sCD305 and CD3060 were quantitated with sandwich ELISA. The data were analyzed by using student t test. Results sCD305 was skewness distributed in both 2 groups, was 0.000-3.039 μg/L in CMV pneumonitis group and 0.000-8.375 μg/L in con-trol group. CD3060 was skewness distributed in CMV pneumonitis group and the concentration was 0.000-0.017μg/L. CD3060 was mormally distributed in control group and the concentration was 0.046±0.035 μg/L. There was significant difference of CD3060 (P=0.000) concentrations and no sig-nificant difference of sCD305(P=0.316) concentrations in 2 groups, respectively. Conclusions The concentration of CD3060 is low in CMV pneumonitis patients. The combination of CMV PP65 antigen detection and CD3060 detection is helpful for the early and precise diagnosis of CMV pneumonitis in renal transplantation patients.

Objective To observe the protein expressions of PI3Kp110, pAkt, pGSK3β of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt) signaling pathway in the whole blood of patients with Kashin-Beck disease and analyze the status of PI3K/Akt signaling pathway. Methods Patients with Kashin-Beck disease ( KBD group ) were from six counties ( Xunyi , Linyou , Yongshou , Qianyang , Changwu and Long County) of Shannxi Province in Kashin-Beck disease areas , and the healthy controls (control group) were matched by age and sex. Venous blood was collected from patients and healthy controls. Trizol method was applied to extract the whole blood protein; protein expression levels of PI3K/Akt signaling pathway in whole blood were detected by Western blotting; the gray values were observed and recorded by the sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE) and GDS-8000 gel imaging analysis system. Differences between the two groups were assessed by Student’s t-test. Results Compared age and sex between KBD group and control group, differences were not statistically significant(t=0.701, P>0.05;χ2=0.400, P>0.05). The protein expression levels of PI3Kp110, pAkt and p-GSK3β in KBD group were higher than that in control group(156.1 ± 92.1 vs. 79.5 ± 21.5, 113.7 ± 15.2 vs. 43.3 ± 10.7 and 105.9 ± 17.5 vs. 37.3 ± 12.0, respectively) and the differences were statistically significant (t=2.563, 6.567, 7.916; all P < 0.05 or < 0.01). Conclusion The PI3Kp110, pAkt and p-GSK3β expressions of signaling pathway proteins in the whole blood of patiens with Kashin-Beck disease are up-regulated significantly and the status of PI3K/Akt signaling pathway is activated.

Objective To assess the role of 68Ga-N,N′-bis(2-hydroxy-5-(carboxyethyl)benzyl) ethylenediamine-N,N′-diacetic acid(HBED-CC)-(Ahx)Lys-CO-Glu(PSMA-11) PET/CT on the detection of metastatic lesions from castration-resistant prostate cancer (CRPC).Methods Sixteen patients with CRPC who underwent 68Ga-PSMA-11 PET/CT between January 2015 and November 2015 were recruited in this study.Mean age of patients was (72±9) years.The PSA levels were 4-12 356 μg/L, Gleason score was 7-10.PET/CT was performed at 1 h postinjection of 68Ga-PSMA-11.Patient-based analysis and lesion-based analysis were performed.ROI analysis was used to calculate the tumor uptake (SUVmax).Final diagnosis was based on histopathology and results of other imaging examinations(99Tcm-MDP imaging, MRI).χ2 test was used to compare the diagnostic efficiencies of PET and CT.Results No adverse effects were observed in patients.68Ga-PSMA-11 PET/CT showed moderate physiologic uptake in salivary glands and proximal small intestine, with predominant tracer clearance by the kidneys.All patients were positive on 68Ga-PSMA-11 PET/CT.Bone metastasis was found in 16 patients, liver metastasis in 2 patients (5 lesions), and lymph node metastasis in 4 patients (26 lesions).The SUVmax of liver, lymph node and bone metastases were 15.06±2.77, 7.54±5.20, 19.01±16.96, respectively.The diagnostic sensitivity, specificity and accuracy on bone metastasis with 68Ga-PSMA-11 PET and CT were 96.30%(52/54) vs 61.11%(33/54), 3/3 vs 1/3, 96.49%(55/57) vs 59.65%(34/57).The sensitivities and accuracies of the two modalities were significantly different(χ2=19.943, 22.593, both P<0.01).Conclusions 68Ga-PSMA-11 PET/CT could precisely detect both primary and metastatic lesions of CRPC, suggesting that it is of great value for the clinical management and treatment.

Objective To investigate the effect of POSTN protein on the proliferation of chondrocytes of tibial plateau in old rats.Methods Cartilage cells collected from the tibial plateau of old rats were cultured in vitro to the third generation.Then the cells were divided into 3 groups:POSTN group,PBS group and POSTN antibody group.The proliferations of the three groups at 24 h,48 h and 72 h were determined by EDU method.The expression of Notch1 protein was detected by immunohistochemistry in all groups at the same time.Female 20-month-old Sprague-Dawley rats were randomly divided into 3 groups:POSTN protein injection group,Phosphate Buffered Saline (PBS) injection group and POSTN antibody injection group.Twelve weeks after the operation,related reagents were injected 3 times consecutively at day 1,day 3,day 5 and EDU was injected into joints at day 1.At 2 weeks after injection,the rats were killed and the knee tibial plateau was taken to observe the proliferation of the cartilage cells.Results At 24 h,there were differences between the three groups O(F=27.32,P=0.017).The proliferation rates of POSTN group [(23±8)％] and PBS group [(21±10)％] were higher than that of POSTN antibody group (16±5)(P=0.003,P=0.011).At 48 h,there were differences between the three groups (F=35.34,P＜0.01).The proliferation rate of POSTN group [(36±11)％] was higher than that of the other groups [(22±6)％],(18±6)％(P=0.021,P＜0.01).At 72h,there were differences between the three groups (F=52.62,P=0.000).The proliferation rate of POSTN group [(56±17)％] was the highest one,the proliferation rate of PBS group [(31±8)％] was the medium,and the POSTN antibody group [(26±7)％] was the lowest one (all P＜0.05).As for Notch1 protein expression in chondrocytes,there were differences between the three groups (F=26.72,P＜0.01).The Notch1 protein was the most frequently expressed in POSTN protein-injection group and the least in the anti-POSTN group.In rats,the proliferation rate of the chondrocytes in the medial tibia plateau of the knee of POSTN protein injection group [(36±14)％],which was the highest,and that of the POSTN antibody injection group [(10 ±4)％] was the lowest (all P＜0.05).Conclusion POSTN protein can promote the proliferation of chondrocytes knee OA rats.POSTN antibody injection has been shown to induce the proliferation of chondrocytes.The POSTN protein may promote the proliferation of chondrocytes by activating the Notch signaling pathway.
