This study was aimed to observe the effect of Danzhi Jiangtang Capsule ( DJC ) on expression of solu-ble thrombomodulin ( sTM ) and soluble endothelial cell protein C receptor ( sEPCR ) in experimental rats of type 2 diabetes mellitus (T2DM). This study also explored possible mechanisms of Yiqi Yangyin Huoxue method on vascular endothelial tissue and discussed mechanisms of prevention and management of T2DM vascular lesions . A total of 60 male Sprague-Dawley ( SD ) rats were fed for one week and then randomly divided into the nor-mal control group ( group N , n = 12 , rats were fed with routine food ) and diabetes mellitus group ( n = 48 , rats were fed with high-fat diet). After 4 weeks, rats in the diabetes mellitus group were injected with strepto-zotocin ( STZ ) to induce T2DM . According to the blood glucose level , rats were divided into three groups , wh ich were the model group (group M), pioglitazone (group P), and pioglitazone combined with DJC (group D). Group P was treated with pioglitazone (10 mg?kg-1?d-1), group D was given pioglitazone (10 mg?kg-1?d-1) and DJC ( 0 . 47 g?kg-1?d-1 ) . The group N and group M were treated with sodium chloride ( 5 mL?kg -1?d-1 ) . After four-week drug administration , the levels of sTM , sEPCR , PT , APTT and FIB in each group were tested . The results showed that compared with the control group , the levels of sTM , sEPCR and FIB in group M , group P and group D were significantly increased ( P < 0 . 05 ) , and the levels of PT and APTT were obviously reduced ( P < 0 . 05 ) . Compared with group P , the levels of sTM , sEPCR , FIB of group D were significantly reduced ( P< 0 . 01 ) , and the level of APTT was significantly increased ( P < 0 . 05 ) . However , there was no significant dif-ference in the increasing of PT. It was concluded that the Yiqi Yangyin Huoxue method can reduce the levels of sTM and sEPCR , and effectively improve coagulation . The possible mechanisms of protective effect on the vascular endothelium can be from reducing levels of sTM and sEPCR in order to enhance the activity of anti-coagulation and fibrinolysis , regulate the function of blood coagulation to improve hypercoagulable state .

ObjectiveTo determine the serum level of anti-aminoacyl-tRNA synthetase (ARS)antibody in patients with polymyositis (PM) and dermatomyositis (DM) and to investigate the value of anti-ARS antibody for diagnosing interstitial lung diseases(ILD) in patients with PM/DM compared with anti-Jo-1 antibody.MethodsSerum anti-ARS antibody concentrations were measured by ELISA in 109 adult PM/DM patients,20 patients with SLE,20 patients with RA and 50 healthy controls.T test,Mann-Whitney U test,chi-square test or Fisher exact test were used to compare the sensitivity and specificity for diagnosing ILD in PM/DM patients between anti-ARS antibody and anti-Jo-1 antibody.Moreover,McNemar test was employed to analyze the correlation between the clinical features and anti-MDA5 antibody in PM/DM patients.Results The serum positive rate of anti-ARS antibody was 37.9％,7.8％,10％,0 and 0 in PM/DM patients with ILD and without ILD,patients with SLE and RA and healthy controls,respectively.Serum anti-ARS antibody levels and positive rate in the PM/DM patients with ILD were significantly higher when compared with PM/DM patients without ILD,patients with SLE and RA and healthy controls (X2=-13.5,5.45,10.57,15.17; P＜0.01 ).Anti-ARS antibody presented a significantly higher sensitivity for diagnosing ILD in patients with PM/DM compared to anti-Jo-1 antibody (P＜0.01).The rate of fever and ILD were significantly higher in anti-ARS positive group than anti-ARS negative group(X2=12.55,13.53; P＜0.05),while heliotrope rash and shawl sign occurred more often in anti-ARS negative group(X2=5.7,5.8; P＜0.05).Additionally,follow-up study showed that the serum anti-ARS antibody were all negative in nine patients who died of PM/DM with ILD (P＜0.05).ConclusionSerum anti-ARS antibody is a stronger predictor for early diagnosis of PM/DM with ILD compared to anti-Jo-1 antibody.The detection of anti-ARS antibody can be widely applied to clinical practice.

Objective To evaluate the valuse of endoscopic ultrasonography ( EUS ) for upper gastrointestinal submucosal lesions and the role of Photoshop in differentiating leiomyoma and stromal tumors. Methods Data of 656 patients with upper gastrointestinal submucosal lesions evaluated by EUS and receiving endoscopic submucosal dissection ( ESD ) from April 2010 to March 2015 were collected and retrospectively analyzed. The goldern standard for lesions size and origin was the intraoperative diagnosis of ESD, and that of the type of lesions ( leiomyoma, stromal tumor, ectopic pancreas, lipoma, etc.) was pathological and immunohistochemical finding. The consistency of diagnosis of the EUS was evaluated. In addition, Photoshop was used to differentiate diagnosis of leiomyoma and stromal tumors which were confirmed by pathology and immunohistochemistry. Results The consistency in diagnosing the size and lesion origins was 92?56%(560/605) and 88?43%(535/605)between EUS and ESD intraoperative result. The consistency in pathological types of EUS was 79?34%(480/605). Photoshop was used to analyze the EUS images of 177 stromal tumor and 241 leiomyoma. The gray value of stromal tumor was significantly higher than that of leiomyoma(59?97 VS 39?39, t=43?27, P<0?05).The echo of stromal tumor was higher. The standard deviation of gray value of leiomyoma were significantly lower than that of the stromal tumor ( 4?81 VS 5?42, t = 2?83, P < 0?05 ) , indicating the echo uniformity of leiomyoma was better. Conclusion EUS shows high accuracy rate for upper gastrointestinal submucosal lesions, providing more accurate basis for endoscopic therapy. EUS combined with Photoshop is helpful for differentiating stromal tumor from leiomyoma.

Objective To investigate the expression and prognostic significance of P-JAK2, P-STAT3 and mutant p53 in cervical lesions. Methods A total of 153 cervical biopsies of patients from Gynecology Department, The Second Hospital of Tianjin Medical University were recruited during December 2013 to June 2015. Fifty-seven cases of squamous carcinoma of cervix (SCC), 36 cases of low grade intraepithelial neoplasia (LSIL), 30 patients with high grade intraepithelial neoplasia (HSIL) and 30 cases of normal cervix (NC) were included in the study. Gene chip method was used to detect high-risk hu-man papillpmavirus(HR-HPV)infection. Hematoxylin-eosin staining was used to make pathological diagnosis. Immunohis-tochemical assay was used for the detection of P-JAK2, P-STAT3 and mutant type p53 protein expression in cervical le-sions. Results (1) HR-HPV infection rate and P-JAK2 expression were significantly higher in SCC group than those of HSIL group, LSIL group and NC group (P<0.05). (2) The expression of P-STAT3 and mutant type p53 were significantly higher in SCC group than those of LSIL group and NC group (P<0.05). However, there was no significant difference between SCC group and HSIL group. (3) The positive expressions of P-JAK2 and P-STAT3 showed significant differences in different FIGO stages, histopathological grade, lymph node metastasis and HR-HPV infection in SCC group, respectively ( P<0.05). There were significant differences in the positive expression of mutant type p53 between different FIGO stages and HR-HPV infection (P<0.05). (4) There was positive correlation between P-JAK2, P-STAT3, positive expression of mutant type p53 and HR-HPV infection in SCC tissues (P<0.05). There was a positive correlation between P-STAT3, p53 expression and HR-HPV infection (P<0.05). There was a positive correlation between mutant p53 expression and HR-HPV infection (P<0.05). Conclusion P-JAK2, P-STAT3 and mutant p53 protein expression rates are high in SCC group than those of NC and SIL groups, which may be associated with HR-HPV infection, cervical cancer occurrence and progression.

Objective To evaluate the clinical outcomes and correction accuracy of posttraumatic varus and valgus knee deformities using the Taylor Spatial Frame (TSF).Methods From June 2006 to December 2010,26 patients with posttraumatic varus and valgus knee deformities who had been treated with the TSF combined with less invasive high tibial osteotomy (HTO) or supracondylar femur osteotomy (SFO) were retrospectively analyzed,including 19 males and 7 females with an average age of 39 years.There were 20 cases of posttraumatic varus knees and 6 valgus knees.Twenty one patients were treated with HTO and 3 with SFO,2 with HTO and SFO simultaneously.During the operation,the TSF was firstly assembled and then the parameters of the frame were measured followed by less invasive percutaneous osteotomy.Correction was started seven to ten days after the operation following the time schedule provided by the computer program.Correction of the struts were performed 3 times per day,with a total movement of 0-3 mm.Results Through 7-35 days frame adjustments,20 cases of deformities were fully corrected.X-ray showed that the mechanical axis deviations of the tibia and femur all were recovered to normal range,and the deformity of rotation,angulation and crispation were fully corrected.Six cases had residual slight angulation or crispation deformity ( ＜ 4° or ＜ 10 mm).Through the second 4-10 days frame adjustments,these 6 cases of deformities were fully corrected finally.New bone formation and consolidation on the osteotomy site were good.The fixators were removed from 2.5-6.0 months after surgery and the appearance of the limbs and the patients' gait recovered to normal and the keen pain disappeared.All patients were followed up for 12-60 months and without the recurrence of the deformity.Eleven cases occured pin site infection and were controlled by use of the sensitive antibiotics.One case occured refracture of the distal femur osteotomy site 1.5 months after frame removal.Through conservative treatment,the fracture finally healed.Conclusion Posttraumatic varus and valgus knee deformities can be effectively corrected by using TSF and with a high accuracy.

Objective To discuss the influence of comprehensive rehabilitative nursing by traditional Chinese medicine(TCM)the neural function impairment, activity of daily living(ADL)and accompanying complications of patients in acute phase of cerebral apoplexy. Methods 238 patients from 3 cooperative hospitals from September in 2004 to September in 2006 were randomly chosen and divided into the test group(117 cases)and the control group(121 cases).The medication treatment in the two groups were basically the same. The comprehensive rehabilitative nursing with traditional Chinese medicine was adopted in the test group and the control group received routine nursing intervention. The clinical nerve function limitation score(CNS)and the ADL were evaluated within the first week and the 4th week after intervention. The incidence rate of complications was also determined. Results The CNS and ADL results in the observation group were better than those in the control group(P＜0.01).The incidence rate was lower than that in the observation group. Conclusion The comprehensive rehabilitative nursing by TCM could facilitate the functional recovery of limbs and improve activity of daily living.This intervention could be applied in clinic, family and community because of its characteristics such as simplicity, feasibility and little adverse effect.
