Then the patients were scheduled to undergo HSG.The experimental group was undergone constant speed pump injection and control group manual injection.Observe the effectiveness of the two methods on patients in two groups,respectively.Results The excellent rate of the images in experimental group (94.55%)was significantly higher than the control group (85.45%)and the risk of adverse reactions were significantly decreased in the former.There was statistical difference between the two groups.Conclusion Constant speed infusion pump is a convenient,safe and effective method in hysterosalpinography compared with manual injection,which is worthy of application in clinic.

Objective To study the relation between the levels of protein C(PC),protein S(PS),antithrombin Ⅲ(AT-Ⅲ)with cerebral infarction.Methods 126 patients with cerebral infarction were divided into the groups according to the age,onset time and infarction area and contemporaneous 30 individuals with healthy physical examination were selected as the control group.The levels of PC,PS and AT-Ⅲ were detected.The relation between the change of these indicator levels with the age,onset time and infarction area was analyzed Results The levels of AT-Ⅲ,PC and PS in the acute stage youth group were lower than those in the acute stage middle age and elderly group with statistical differences between them (P <0.05).The level of the AT-Ⅲ,PC and PS in the acute stage group were lower than those in the recovery stage group and the control group,difference had statistical significance(P <0.05).The levels of AT-Ⅲ and PS in the recovery stage group were lower than those in the control group with statistical difference (P <0.05),but the level of PC had no statistical difference between the recovery stage group and the control group.The further study found that the level of AT-Ⅲ,PC and PS in the small infarction group,middle infarction group and large infarction group showed the gradually decreasing trend,the differences had statistical significance (P <0.05).Conclusion The decrease of AT-Ⅲ, PC and PS levels is the importan factor of cerebral infarction occurrence and is closely correlated with cerebral infarction ocurrence especially in the patients less than 45 years old.Observing the change of PC,PS and AT-Ⅲ levels has the important significance for judging the cerebral infarction progression.

Objective To explore the folate receptor mediated (FRD) check and multi-function acetic acid white solution liquid based cervical cytology (TCT) application value in cervical cancer screening.Methods A total of 602 cases of patients was tested with FRD multi-function acetic acid white solution check,and TCT and cervical biopsy pathology examination.With the used of histopathological results as the gold standard,FRD multi-function acetic acid white analysis was compared with the TCT screening inspection results.Results For a total 602 patients with TCT screening,the positive rate was 21.8％ (131/602),including 36 cases of CIN Ⅰ level,41 cases of CIN Ⅱ level,24 cases of CIN Ⅲ level,and 30 cases of cervical invasive carcinoma.For the FRD multifunction white acetate solution screening,its positive rate was 23.8％ (143/602).No statistically significant difference was found between TCT and FRD screening (P ＞ 0.05).The missed diagnosis rate of FRD multi-function white acetate solution screening was 2.6％ in inflammation,and 21.1％ in cervical invasive cancer,and 3.8 ％ in CIN.The missed diagnosis rate of TCT screening was 7.2％ in inflammation,5.3％ in CIN Ⅰ,4.9％ in CIN Ⅱ,and 58.6％ in CIN Ⅲ]; whereas,its detection coincidence rate was 100％ in squamous cells carcinoma (SCC) and adenocarcinoma (AC).FRD multi-function acetic acid white solution screening had a sensitivity 80.92％,specificity 92.14％,positive predictive value 74.13％,and negative predictive value 95.59％.TCT examination had a sensitivity 90.84％,specificity 90.23％,positive predictive value 72.12％,and negative predictive value 97.25％.No significant difference was found between FRD and TCT methods (P ＞ 0.05).Conclusions FRD and TCT methods were both efficient in screening and evaluation for cervical lesions and cervical cancer.Because FRD method is limited in the deep tube for examination of cervical lesions; it cannot completely replace the TCT examination.However,FRD method is reliable,economic,and simple operation; it is suitable for primary hospitals census of cervical cancer

Objective To study the effect of paeonol (PAE) and panax notoginseny saponins (PNS) on the expressions of collagenⅠandⅢprotein and mRNA in rats with acute myocardial infarction (AMI), and to explore the molecular mecha?nism of improving myocardial fibrosis. Methods The rat model of AMI was made using the left anterior descending coro?nary branch ligation.According to the intervention rats were divided into model group, PAE (8 mg/kg) group, PNS (40 mg/kg) group, PAE (4 mg/kg)+PNS (20 mg/kg) group, PAE (8 mg/kg)+PNS (40 mg/kg) group and captopril positive control group (10 mg/kg). Sham operation group, only wear line without ligation. The left ventricular mass index (LVMI) was detected after treatment for 28 d. Masson staining was used to observe changes of myocardial fibrosis. Western blot assay and RT-PCR technique were used to detect protein and mRNA expression levels of collagenⅠandⅢ. Results The values of LVMI were increased in model group compared with those of sham operation group and treatment groups. Compared with PAE group and PNS group, values of LVMI were significantly decreased in PAE (4 mg/kg)+PNS (20 mg/kg) group and PAE (8 mg/kg)+PNS (40 mg/kg) group. There was a more significant decrease in formula high dose group (P < 0.01). The model group showed pathological change. There were different degrees of improvement in pathological structure in all treatment groups, more sig?nificant improvement was found in formula low dose group, formula high dose group and captopril positive control group. There were different degrees of increase in expressions of collagenⅠandⅢprotein and mRNA in model group compared with those of sham operation group and treatment groups. Compared with PAE group and PNS group, the protein and mRNA expression levels of collagenⅠandⅢwere significantly decreased in formula low dose group and formula high dose group,more significant decreased was found in formula high dose group (P<0.05). Conclusion Compound of paeonol and PNS can improve myocardial fibrosis in myocardial infarction rats, which may be related with reduced expressions of collagenⅠandⅢprotein and mRNA.

Objective To study the effect of paeonol (PAE) and PNS on the expression of transforming growth factor (TGF)- beta 1/ Smad2/3 pathway in rats with acute myocardial infarction (AMI), and the possible molecular mechanism thereof. Methods Model of AMI was made using left anterior descending coronary branch ligation. According to the inter?vention methods rats were divided into model group, PAE group (8 mg·kg-1), PNS group (40 mg·kg-1), PAE (4 mg·kg-1)+PNS (20 mg·kg-1) low dose group, PAE (8 mg·kg-1)+PNS (40 mg·kg-1) high dose group and captopril positive control group (10 mg · kg-1). Rats without ligation were used as Sham operation group. Left ventricular systolic blood pressure (LVSP), left ventricular diastolic pressure (LVEDP) and the maximum rise and fall rate (/dtmax DP) were detected after 28-day treat?ment. HE staining was used to observe changes of myocardial tissue. The protein expression levels of TGF-β1 and Smad2/3 were detected by Western blot assay. Results There were significant differences in parameters used for detecting treatment group and model group, formula group and single drug group, formula high dose group and formula low dose group (P <0.01). The model group showed pathological changes. All treatment groups showed different degrees of pathological improve?ment. There was the most significant improvement in formulae group and captopril group. Compared with the model group, TGF-β1 and Smad2/3 protein expressions were decreased in treatment group. The expression levels of TGF-β1 and Smad2/3 were significantly decreased in formula group than those of PAE group and PNS group, and lower levels in formula high dose group than those of formula low dose group (P<0.05). Conclusion Paeonol and PNS can inhibit the expressions of TGF-β/Smad 2/3 protein in rats with AMI, by blocking TGF-β/Smad pathway.

Objective To evaluate short-term and long-term prognosis of revascularization in patients with acute coronary syndrome. Methods A total of 6005 patients who received coronary revascularization in our institution between July 2003 and September 2005 were enrolled. The patients were followed up in clinic or by telephone after discharge between September 2006 and November 2006. The clinical and prognosis data of all-cause mortality, neo-myocardial infarction, nonfatal stroke, and rerevascularization of ST-segment elevation myocardial infarction ( STEMI ) , non ST-segment elevation myocardial infarction ( NSTEMI) and major adverse cardiovascular and cerebrovascular events ( MACCE) were analyzed. Results Among 4865 acute coronary syndrome patients, 955 cases were STEMI; 263 cases were NSTEMI; and 3647 cases were unstable angina ( UA) pectoris. There were no significant difference for in-hospital mortality and late mortality ( 18 month survival 96% , 98% and 98% ) between patients with STEMI, NSTEMI and UA. Patients with UA had lower MACCE rate (18 month non-MACCE survival of STEMI, NSTEMI and UA group were 86% , 86% , and 89% respectively). Conclusions Despite different clinical characteristics, patients with STEMI, NSTEMI and UA undergoing revascularization had similar short-term and long-term mortality. Patients with UA had lower MACCE rate.

This study determined the profile of renal insufficiency in patients without chronic kidney disease(CKD)undergoing coronary revascularization and elucidated the effect of renal insufficiency of different degrees on clinical outcomes after revascularization and examined whether the reasonable choice of the mode of revasoularization could favourably influence prognosis.Methods Patients undergoing coronary revascularization were grouped by estimated creatinine clearance(CrCl)(Group Ⅰ,CrCl≥90 ml/min;Group Ⅱ,60 CrCl<90 ml/min;Group Ⅲ,30≤CrCl<60 ml/min;Group Ⅳ,CrCl<30 ml/min).We evaluated the relationship between the CrCl and the clinical outcomes of all of the patients.Results The mean Scr level of 2896 patients was(80.0±35.4)μmol/L There were 1035 patients(35.7%)in Group Ⅰ,1337 patients(46.2%)in Group Ⅱ,524 patients(18.1%)in Group Ⅲ and no patient in Group Ⅳ.During hospitalization,significant difference was found among Group Ⅰ-Ⅲ on mortality (1.0%.2.5% and 2.9%,P=0.009)and major adverse cardiar cerebra tvents(MACCE)(1.4%,3.5% and 4.6%.P=0.001).Compared with the normal renal function group,there were significantly higher rate of mortality(2.5% vs.1.0%,P=0.007).new-onset myocardial infarction(1.0% vs.0.2%,P=0.018)and MACCE(3.5% vs.1.4%,P=0.002)in miid renal insufficiency(Group Ⅱ).During follow-up,there were significant difference among Group Ⅰ-Ⅲ on mortality(2.0%,3.0% and 5.7%,P=0.002),stroke(1.0%,1.8% and 3.1%,P=0.023)and MACCE(9.9%,10.3% and 16.6%,P=0.001).The independent risk factors for all-cause death in patients after revascularization were the mode of revascularization(OR 8.332,95% CI 2.386-22.869,P=0.001).age(OR 1.184,95% CI 1.020-1.246,P=0.001).and the level of CrCl(OR 0.503,95% CI 0.186-0.988,P=0.045).In patients with normal renal function and mild renal insufficiency.the all-cause mortality after PCI was significantly lower that than after CABG(both P<0.01).Conclusions Renal insufficiency is common in patients without CKD undergoing coronary revascularization,even mild renal insufficiency is correlated with adverse clinical outcomes after revascularization.In patients with normal renal function or mild renal insufficiency,the mode of revascularization might lead to a prognostic difference.

Background:The diagnostic accuracy of APRI and FIB-4 for liver fibrosis in patients with chronic hepatitis B is nothigh,especially for significant liver fibrosis (F≥2). Noninvasive diagnosis for liver fibrosis has become a research hotspot;and the diagnostic value of APRI combined with FIB-4 is not clear. Aims:To investigate the diagnostic value ofAPRI combined with FIB-4 for significant liver fibrosis in patients with chronic hepatitis B. Methods:A total of 171patients with chronic hepatitis B from January 2011 to October 2016 at General Hospital of Xinjiang Military Region wereenrolled. Liver biochemical indices,routine blood test and liver biopsy pathology were performed. APRI and FIB-4 werecalculated,ROC curve was drawn,and cutoff value of APRI and FIB-4 for diagnosing significant liver fibrosis wasdetermined,and mode of APRI combined with FIB-4 for diagnosing significant liver fibrosis was established. Results:Withthe increase in degree of liver fibrosis,APRI and FIB-4 were gradually increased (P < 0. 05). Area under ROC curve(AUC)for APRI and FIB-4 were 0. 812 and 0. 770,respectively. The sensitivity of FIB-4 for diagnosing significant liverfibrosis was higher than that of APRI. Sensitivity,specificity,negative predictive value,positive predictive value,andaccuracy of APRI combined with FIB-4 for diagnosing significant liver fibrosis were superior to APRI or FIB-4 used alone;and the specificity,accuracy of mode 2 were superior to mode 1. Conclusions:APRI combined with FIB-4 can increasethe accuracy for diagnosing significant liver fibrosis.

Objective To study the role of endothelial cells on the inflammatory cytokine release in septic shock through the septic shock serum stimulating human primary endothelial cells (HPAEC) and peripheral blood mononuclear cells(PBMC).Methods PBMC isolated from healthy people by density gradient centrifugation.HPAEC cell surface markers CD144 and von Willebrand factor(vWF) molecule expression by RT-PCR and Western blot.Serum levels of IL-6,TNF-α,MCP-1 from septic shock patients and healthy human detected by ELISA.HPAEC and PBMC were stimulated with the isolated serums and LPS,respectively.ELISA was used to detect the supernatant IL-6,TNF-α,MCP-1 levels.HPAEC membrane molecules ICAM-1 expression was detected by flow cytometry with serum shock and LPS stimulation.Supernatant levels of IL-6,TNF-α,MCP-1 of HPAEC with S1P1 receptor agonist CYM-5442 pretreatment was detected by ELISA after shock serum stimulation.Results Endothelial cell markers CD144 and vWF molecules could be detected in the HPAEC.Levels of inflammatory cytokines IL-6,TNF-α,MCP-1 in patients with septic shock serum were significantly higher than healthy people (P＜0.01).PBMC and HPAEC with LPS or shock serum treatment respectively,compared with normal group,levels of inflammatory cytokines in the culture supernatant were significantly higher(P＜0.01).For PBMC,the level of inflammatory cytokines between shock group and LPS group were not significantly different (P＞0.05).But for HPAEC,levels of inflammatory cytokines in the supernatant of the shock group compared to the LPS group was significantly higher (P＜0.01).Similarly,when two cells after LPS stimulation,IL-6,TNF-α levels of HPAEC's supernatant were significantly lower than PBMC' s (P＜0.01),MCP-1 levels was no difference (P＞ 0.05).But when the stimulation of shock serum,HPAEC of IL-6,TNF-α levels and PBMC no significant difference (P ＞0.05).MCP-1 was significantly increased (P＜0.01).Shock patients serum stimulation S1P1 receptorspecific agonist CYM-5442 pretreatment of HPAEC with pretreatment of S1P1 receptor specific agonist CYM-5442,the culture supernatant of inflammatory cytokines IL-6,TNF-α,MCP-1 levels were significantly lower (P＜0.01).Conclusion Endothelial cells may play a central role on the release of inflammatory cytokine during septic shock.
