Objective To explore the regulating mechanism of inducible nitric oxide synthase(iNOS) in hepatic injury of obstructive jaundice (OJ) in vivo and in vitro experiments. Methods (1) Rat hepatocytes were isolated by in situ collagenase perfusion and primary culture. Hepatocytes were pretreated with various concentrations of iNOS inhibitor SMT for 20 min. After pretreatment, 50?M GCDC was added for an additional 24hr. Cells were next detected by FCM and TUNEL.(2) Experimental obstructive jaundice (BDL) was induced by double ligation of the bile duct in rats. After BDL for 3d、7d、14d、and 21d, the apoptotic status in liver of all rats were determined with TUNEL, and iNOS protein in liver of OJ was ditermined with immunohistochemistry method. Results (1) SMT decreased GCDC-induced apoptosis in a concentration-dependent manner. (2) The apoptotic rate of liver was related to length of time of OJ. Apoptosis index (AI) was highest from rats with 14d bile duct ligation. The stronger the iNOS expression, the higher was the number of apoptotic cells that was found in OJ. Conclusions iNOS is involved in the regulation and the occurrence and progression of hepatic injury of obstructive jaundice.

Objective To evaluate the effect of silver needle injection therapy on rat with sports muscle injury. Methods Twenty-one healthy male Wistar rats were randomly divided into the injury group (n = 3),the silver needle group (n=12) and the control group (n=3). The expressions of bFGF and GDNF in gastrocnemius muscle tendon junction were detected on 7 d ,14 d and 28 d post-injury. Results No significant difference in the appearance of the injured tissue was found in both two groups on 7 d post-injury. The appearance of the injured tissue was better in the silver needle group than that in the control group on 14 d and 28 d post-injury. The tissue was almost normal in the therapy group on 28 d post-injury; The expression of bFGF in the therapy group was higher than that in the injury control group on 7 d and 14 d post-injury (P < 0.01). The expression of bFGF markedly decreased in the therapy group compared with the control group (P < 0.01) on 28 d post-injury. The expression of GDNF in the therapy group was higher than that in the injury control group on 7 d ,14 d and 28 d post-injury (P<0.01). Conclusion The silver needle injection therapy has the therapeutic effect on sports muscle injury reparation, which can increase the expression of bFGF and GDNF efficiently.

Objective To investigate the expression of protease-activated receptors (PARs) in colon mucosal tissue of patients with diarrhea-predominant irritable bowel syndrome (D-IBS). Methods Colon mucosa tissues were obtained from 28 D-IBS patients and 18 normal controls by colonoscopy.The expression of PARs was detected using Western blotting and real-time PCR. Data were analysed by SPSS 18. 0 softwave, and comparisons between groups were done using Mann-Whitney U test.Results There was no difference in expression of PAR1 between D-IBS patients and normal controls (P=0. 300). The expressions of PAR2 and PAR4 were higher in D-IBS patients than those in normal controls (0.99±0.67 vs 0.63±0.38, P=0.038 and 0.37±0. 14 vs 0.25±0. 11, P=0.013,respectively). The results of real-time PCR were in accordance with those of Western blotting.Conclusion The increased expressions of PAR2 and PAR4 in colon mucosa of D-IBS patients indicate that these two PAR receptors may be involved in the process of D-IBS.

Objective Rapid elevation of the IgG antibody against Candida Enolase ( Eno ) has been observed in patients with invasive candidosis in an early stage .The present study was to confirm the association of Candida colonization with humoral im-mune anamnestic response of the dominant antigen . Methods Twenty-four mice were randomized into group 1 treated by oral Candi-da colonization plus intraperitoneal infection ( immunocompetent , n=8) , 2 treated with immunosuppressant in addition to the treatment of group 1 ( immunocompromised , n=8) , 3 treated by oral Candida colonization only ( immunocompetent , n=4) and 4 treated by in-traperitoneal injection only( immunocompetent, n=4).The number of Eno-specific memory B-cells in the spleen and the levels of IgG , IgM and IgA antibodies were determined in the peripheral blood of the immunocompetent and immunocompromised invasive candidiasis mice . Results At 7 days after invasive infection , there were significantly more Eno-specific memory B-cells in the mice of groups1 ( 47.25 ± 13.81) and 2 (43.14±15.95) than in groups 3 (8.00±3.74) and 4(8.50±2.38) (P<0.01), with no statistically significant differences between either groups 1 and 2 or groups 3 and 4 (P >0.05).Eno-IgG antibodies were detected in the serum of the mice of the first two groups in the early stage of invasive infection and positively corre -lated with antigen-specific memory B-cells (r=0.737,P <00.1 ). Conclusion Rapid elevation of the Eno-IgG antibody level in the early stage of invasive infection after Candida colonization may be attributed to the rapid proliferation of humoral immune memory cells.

OBJECTIVETo assess the stiffness and thickness of the plantar fascia using shear wave elastography (SWE) in healthy volunteers of different ages and in patients with plantar fasciitis.
METHODSThe bilateral feet of 30 healthy volunteers and 23 patients with plantar fasciitis were examined with SWE. The plantar fascia thickness and elasticity modulus value were measured at the insertion of the calcaneus and at 1 cm from the insertion.
RESULTSThe elderly volunteers had a significantly greater plantar fascia thickness measured using conventional ultrasound (P=0.005) and a significantly lower elasticity modulus value than the young volunteers (P=0.000). The patients with fasciitis had a significantly greater plantar fascia thickness (P=0.001) and a lower elasticity modulus value than the elderly volunteers (P=0.000). The elasticity modulus value was significantly lower at the calcaneus insertion than at 1 cm from the insertion in patients with fasciitis (P=0.000) but showed no significantly difference between the two points in the elderly or young volunteers (P=0.172, P=0.126).
CONCLUSIONSWE allows quantitative assessment of the stiffness of the plantar fascia, which decreases with aging and in patients with plantar fasciitis.

【Objective】 To explore the precautions of pre-transfusion examination in patients with antibodies to erythrocyte protective solution, discrepant ABO blood typing results, and positive unexpected antibodies, so as to ensure the safety of blood transfusion. 【Methods】 The screen cells were divided into two groups according to the presence or absence of washing reagent red blood cells in normal saline. One group had untreated forward typing cells, antibody screening cells and identification panel, and the other group had saline-washed reverse typing cells, antibody screening cells and identification panel. The experiments were carried out by microcolumn gel method, saline medium method and polyamine method to analyze the effect of red blood cell preservation solution on serum agglutination reaction of specific patients. 【Results】 Among the 8 patients, forward typing was AB (+ ) in 1 patient, B (+ ) in 4, and A(+ ) in 3, and the reverse typing were interfered. The plasma of 8 patients agglutinated with unwashed reverse typing cells (saline tube method), screen cells and identification panels (saline tube method plus cassette method), while not agglutinated with the polybrene method. The interference was eliminated as using washed reverse typing cells (salinetube method), screen cells and identification panels (saline tube method plus cassette method). 【Conclusion】 The erythrocyte preservation solution affected patients’ blood group typing, but not affected the outcome of blood transfusion as no adverse reactions occurred.

Objective To study the effect of muscle energy techniques with visual feedback on the function of postoperative elbow joint. Methods From October, 2015 to August, 2017, 40 patients after operation for elbow fracture were randomly divided into control group (n=20) and treatment group (n=20). Both groups accepted arthrolysis and exercise guidance at home, while the control group accepted routine muscle energy techniques and the treatment group accepted muscle energy techniques with visual feedback, for eight weeks. They were measured with active range of motion (AROM) of elbow flexion and assessed with Disabilities of the Arm, Shoulder, and Hand (DASH) before and after treatment. Results AROM increased in both groups after treatment (t>15.223, P<0.001), and increased more in the treatment group than in the control group (t=3.072, P<0.01); while the DASH score decreased in both groups (t>27.991, P<0.001), and decreased more in the treatment group than in the control group (t=2.222, P<0.05).Conclusion The muscle energy techniques with visual feedback can improve the motion and function of elbow after operation more effectively.

BACKGROUNDThe aim of this research was to analyze the perioperative factors of regular hepatectomy and irregular hepatectomy. The superiority of the clinical application of the two methods was compared in the perioperative period.
METHODSFrom 1986 to 2011, 1798 patients underwent consecutive liver resections with regular hepatectomy and irregular hepatectomy at the Air Force General Hospital of People's Liberation Army and the General Hospital of Chinese People's Liberation Army. Their medical documentation was investigated retrospectively.
RESULTSIn patients on whom regular hepatectomy and irregular hepatectomy were performed, there was no significant difference in perioperative blood loss, complications, in-hospital mortality, hospital stay, and so on. But in regular hepatectomy, operating time was an independent risk factor (P < 0.001, OR = 1.004).
CONCLUSIONSThere was no significant difference between the perioperative risk of regular hepatectomy and that of irregular hepatectomy.

BACKGROUNDA positive association between the ABO blood types and survival has been suggested in several malignancies. The aim of this study was to assess the role of the ABO blood types in predicting the prognosis of Chinese patients with curatively resected non-small cell lung cancer (NSCLC).
METHODSWe retrospectively analyzed 1601 consecutive Chinese patients who underwent curative surgery for NSCLC between January 1, 2005 and December 31, 2009. The relationship between the ABO blood types and survival was investigated. In addition, univariate and multivariate analyses were performed.
RESULTSGroup 1 (patients with the blood type O or B) had significantly prolonged overall survival (OS) compared with group 2 (patients with the blood type A or AB), with a median OS of 74.9 months versus 61.5 months [hazard ratio (HR) 0.83; 95% confidence interval (CI) 0.72-0.96; P = 0.015]. Additionally, group 1 had significantly longer disease-free survival (DFS; HR 0.86; 95% CI 0.76-0.98; P = 0.022) and locoregional relapse-free survival (LRFS; HR 0.79; 95% CI 0.64-0.98; P = 0.024) than group 2. The association was not significantly modified by other risk factors for NSCLC, including smoking status, pathologic tumor-node-metastasis stage, pT category, pN category, and chemotherapy.
CONCLUSIONSThere is an association between the ABO blood types and the survival of Chinese patients with resected NSCLC. Patients with the blood type O or B had significantly prolonged OS, DFS, and LRFS compared with those with the blood type A or AB.
