Objective To study the risk factors of pulmonary embolism and comparison of the effect of different therapy.Methods Risk factors of 182 patients with pulmonary embolism were analyzed retrospectively.The patients were randomly divided into simple drug group and drug joint intervention group.Simple drug group was given heparin and warfarin,or jiont urokinase fibrinolytic therapy.The drug joint intervention group was given the same drug therapy joint vena cava filter implantation and/or catheter broken bolt therapy.After different treatment,the clinical prognosis was compared between the two groups.Results Of 182 patients with pulmonary embolism,the elderly and smoking prevalence rate increased significantly,deep vein thrombosis,cardiovascular disease,cancer,blood system diseases,trauma and surgery,chronic lung disease,fracture and orthopaedic surgery were the main risk factors.The effective rate and mortality between the pure drug therapy group and drug joint intervention group had no significant differences(x2 =0.145,P ＞ 0.05).Conclusion The incidence of pulmonary embolism is closely related to the risk factors.Cancer is one of the important diseases caused by pulmonary embolism.In a timely manner to give the antithrombotic drug treatment has great significance to the prognosis of pulmonary thromboembolism,there was no significant difference compared with the antithrombotic joint intervention.

OBJECTIVETo explore the molecular mechanism of moxibustion at stomach meridian acupoints for precancerous lesions of chronic atrophic gastritis (CAG).

METHODSFifty male SD rats were randomly divided into a normal group, a model group, a stomach meridian group, a control point group and a vitacoenzyme group, 10 rats in each group. The CAG precancerous lesion model was made in all the groups except the normal group. The rats in the normal group and model group were bundled for 30 min per day; the rats in the stomach meridian group and control point group were bundled and treated with moxibustion at stomach meridian acupoints or control points for 30 min per day; the rats in the vitacoenzyme group were treated with intragastric administration of vitacoenzyme, once per day. All the treatment was given for 20 weeks. The pathological morphological change of gastric mucosa was observed under optical microscope; the expression of epidermal growth factor (EGF), transforming growth factor alpha (TGF-alpha), vascular endothelial growth factor (VEGF), gastric mucosal proliferatig cell nuclear antigen (PCNA), argyrophilic protein of nucleolar organizer regions (Ag-NORs) in gastric mucosal cells were detected by enzyme linked immuno sorbent assay (ELISA).

RESULTSCompared with the normal group, in the model group the gastric mucosal cells showed dysplasia and the expression of EGF, TGF-alpha, PCNA, VEGF, Ag-NORs in gastric mucosa cells in the model group was increased significantly (all P < 0.05). Compared with the model group, the gastric mucosa lesion gradually recovered and the expression of EGF, TGF-alpha, PCNA, VEGF, Ag-NORs in gastric mucosal cells was gradually decreased in the stomach meridian group, control point group and vitacoenzyme group, in which the stomach meridian group had the most significant effects (all P < 0.05).

CONCLUSIONMoxibustion at stomach meridian acupoints can obviously decrease the expression of cell proliferative factors in gastric mucosa in rats with CAG precancerous lesions, inhibit the gastric mucosal cell dysplasia, and promote the recovery of gastric mucosa.

Objective To analyze the clinical significance of four kinds of microalbuminuria detection in early diagnosis of iodinated contrast agent damage to kidney by studying four elements in the patients' urine:microalbumin (mAlb),immunoglobulin G (IgG),α1-microglobulin (α1-MG) and β2-microglobulin (β2-MG).Methods 106 patients who have received percutaneous coronary interventional therapy were chosen and divided into group A(angiography dose ＜ 100ml,n =51) and group B (angiography dose ≥ 100ml,n =55) according to the amount of contrast agent used.Changes in the amount of mAlb,IgG,α1-MG and β2-MG levels,serum creatinine(Scr),endogenous creatinine clearance rate(eGFR) in the urine of the patients before and after the surgery were observed.Results Postoperative α1-MG and β2-MG levels in the urine of group A higher than before surgery (t =-6.748,-11.173,all P ＜0.0 5).2 4 hours after the surgery,mA1b,IgG,α1-MG and β2-MG levels in group B were elevated than before surgery,and the differences were significant(t =-6.223,-3.518,-11.532,-10.773,all P ＜ 0.05).Two groups had significant differences in terms of mAlb,IgG,α1-MG and β2-MG levels after the surgery (F =27.306,4.704,5.118,19.011,all P ＜ 0.05).Conclusion Four kinds of microalbuminuria detecting are conducive to early diagnosis of iodinated contrast agent damage to kidney and assessing the damage degree.The contrast agent damage to kidney first occurs as the renal tubular damage.When the contrast agent was used at a dosage of more than 100ml,glomerular damage occurred.

OBJECTIVETo detect the expression levels of programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) in the peripheral blood of patients with oral squamous cell carcinoma (OSCC) and to discuss their biological and clinical significance.

METHODSPD-1/PD-L1 expression on the surface of T-lymphocytes and the counts of T-lymphocyte subpopulations of peripheral blood in 82 patients with OSCC (OSCC group) and 25 healthy controls (control group) were examined via flow cytometry. The expression levels of soluble PD-1 (sPD-1) and soluble PD-L1 (sPD-L1) in the serum were observed through enzyme-link immunology method. The data were tested and analyzed with SPSS 17.0 software.

RESULTSThe percentage of CD8+ T cells in the OSCC group was significantly higher than that in the control group (P<0.05), whereas the percentages of CD3+ and CD4+ T cells as well as CD4+/CD8+ ratio were significantly lower than those in the control group (P<0.05). The positive rates of PD-1 and PD-L1 in CD3+ and CD4+ T cells in OSCC peripheral blood were remarkably higher than those in the control group (P<0.01). Difference was not observed between the expression levels of sPD-1 in the serum of OSCC group and those in the control group (P>0.05), but the average of sPD-L1 was remarkably higher than that in the control group (P<0.05). sPD-L1 expression was related to clinical stage, tumor cell differentiation, and lymph node status (P<0.05) but not related to sex, age, tumor location, and tumor size.

CONCLUSIONT-lymphocyte subpopulations in the peripheral blood of patients with OSCC developed immunosuppression with different degrees. PD-1 and PD-L1 expression levels on the surface of CD3+ and CD4+ T cells significantly increased. Abnormal increase in sPD-L1 expression may be associated with OSCC development.

ObjectiveTo explore the protective effect of low molecular dextran combined with salvia miltiorrhiza injection against kidney damage from contrast agent after percutaneous coronary intervention(PCI) and the effect of preventing kidney damage.Methods120 patients who underwent PCI were randomly divided into two groups:the treatment group( low molecular dextran combined with salvia miltiorrhiza treatment) and the control group,each group 60 cases.The control group was given the conventional treatment,and the treatment group was treated with 250ml low molecular dextran and 16ml salvia miltiorrhiza injection for 7d on the basis of conventional treatment.The levels of blood urea nitrogen ( BUN ),serum creatinine ( SCR),β2 microglobulin ( β2-MG),24h urine protein were detected before and 1 d,6d after surgery.ResultsAt one day after application of contrast agent,the levels of BUN,SCR,β2-MG,24h urine protein were increased,and returned to baseline level at 6th day.The levels of BUN,SCR,β2-MG,24h urine protein of the treatment group were significantly lower than those of the control group at 6th day ( P ＜ 0.05 ).ConclusionThe low molecular dextran combined with danshen injection treatment in the perioperative period could effectively reduce the kidney impairment from contrast agent and the incidence of renal insufficiency.

Objective To study the frequency of cystic fibrosis transmembrane conductance regulator(CFTR)mutations in patients with congenital bilateral absence of vas deferens(CBAVD).Methods Eighty-five CBAVD patients were collected from May 2007 to May 2009.The diagnosis of CBAVD included azoospermia,normal of 4 sex hormone items,absence of seminal vesicle,normal volume of testicular and epididymis dilated siltation.And 85 normal fertile men served as controls.Genomic DNA was isolated from peripheral blood.The mutations of CFTR exons 10,11 were detected by PCR-single strand conformation polymorphism,and direct sequencing was performed on 85 cases of CBAVD and the control males.Results Of the 85 CBAVD,10 cases(11.8％)exhibited an abnormal CFTR gene mutation,with 4 cases I556V,2 cases M469V,and 1 case of E527N,A F508,L558S,S485C.No mutations were detected in 85 controls.There was a significant difference between the 2 groups(x2 =8.606,P =0.003).Conclusions CBAVD might be caused by the CFTR mutations.The frequencies and the spectrum of CFTR mutations might be different from those Caucasian population in the west country.

OBJECTIVETo analyze the existence and the dynamic cell frequencies of human cells in goats transplanted in utero with human hematopoietic stem cell (hHSC) by using fluorescence in situ hybridization (FISH) technique.

METHODSInterphase FISH (IFISH) with human-specific 17-chromosome satellite DNA and/or human-specific Y-chromosome satellite DNA as probes was performed to analyze the presence and proportions of human cells in 13 transplanted goats. Samples were peripheral blood cells, bone marrow smears and liver touch imprint preparations.

RESULTSOf the 13 transplanted goats, eleven were identified to present human cells. Among them, two goats transplanted with human male HSC were found to have human male cells. The results demonstrated that these transplanted goats were human/goat HSC xenogeneic chimeras. Human cell frequencies decreased with the goat age (months), but the longest survival reached 21 months. During the detected life periods of goats, human cell frequencies in peripheral blood, bone marrow and liver tissues were less than 1@1000, but local human cell frequencies of 207.92@1000 and 392.41@1000 were detected in the liver tissues of 2 transplanted goats.

CONCLUSIONSThe existence and long-term survival of human cells in transplanted goats detected by FISH indicated that goats were appropriate recipients for hHSC in utero transplantation. The lower human cell frequencies in blood and bone marrow, and the higher local human cell frequencies in liver tissues suggested that the microenvironment of goat liver tissues might favor the survival, proliferation and differentiation of human cells.

Objective: To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease(CVD)among Kazakhs population. Methods: The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve. Results: The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001); the area under the curve of MS risk score was close to that of Framingham risk score(0.732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61, 9.33, 14.15, 22.29 vs 3.69, 6.36, 8.47, 16.99). Conclusion MS risk score that included age may be a better predictor of CVD among Kazakhs population.

OBJECTIVE: To analyze the status and influencing factors of the health literacy(HL) of college students in a comprehensive university. METHODS: A total of 3 360 students from in a comprehensive university of Xinjiang Production and Construction Corps was selected using multi-stage stratified cluster random sampling method. The HL level of college students was investigated and evaluated with self-edited Xinjiang Construction Corps College Students Health Literacy Questionnaire. RESULTS: The HL level of college students was 17.1%. The HL level of medical students was higher than that of non-medical students(35.4% vs 10.0%, P<0.01). Logistic regression analysis results showed that among the medical students in grade three or four, those with medium and excellent academic achievement, and Han nationality had a positive effect on their HL level(P<0.01). Among the non-medical students, female and medicine related optional courses had a positive effect on their HL level(P<0.05). Students in the sophomore year had a negative effect on their HL level(P<0.05). CONCLUSION: There is a big difference in the level of HL between medical students and non-medical students. Medical college students and non-medical college students have different factors affecting HL, medical education is related to improving HL.

Objective: To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population. Methods: A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves. Results: The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95%CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95%CI 0.805-0.901). Conclusions The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.
