Six cervical discs specimens were obtained in the surgical operation with patients with traumatic cervical injury served as the control. The specimens were analyzed for IL 1?、TNF ? by use of ELISA method, NO was measured by optical density assays. Results The contents of IL 1?,TNF ? and NO in disc of CSM patients increased significantly when compared with the control group. Conclusion The results of the present study indicated that IL 1?,TNF ? and NO may be involved in the pathogenesis of CSM.

ObjectiveTo investigate the efficacy of invasive-noninvasive sequential mechanical ventilation (MV) in senile patients with severe community-acquired pneumonia (CAP).Methods A prospective study was conducted. The patients with severe CAP aged≥ 75 years admitted to Department of Respiratory Intensive Care Unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from November 2012 to July 2014, with refusal to have tracheostomy, were enrolled. All patients meeting the diagnostic criteria of CAP and severe CAP were first admitted into the Department of Emergency, and they were found to need MV without absolute contraindication for noninvasive ventilation (NIV) in RICU. The patients were mechanically ventilated via endotracheal intubation (ETI), and they were randomly divided into invasive-noninvasive sequential MV group (sequential MV group) and conventional MV group. NIV was initiated immediately when patients matched the conditions for early extubation in the sequential MV group. Oxygen therapy (5 L/min) via a Venturi mask was provided when the indications of conventional extubation were met. The baseline data and clinical characteristics were recorded, the risk factors of death were analyzed by logistic regression analysis, and 60-day survival rate was analyzed by Kaplan-Meier curve. Results Ninety-one senile patients with severe CAP were enrolled, among them 28 patients died within 60 days, with a mortality rate of 30.77%. No significant difference in 60-day mortality was found between sequential MV group (n = 44) and conventional MV group [n = 47, 25.0% (11/44) vs. 36.2% (17/47),χ2 = 1.331,P = 0.249]. In the sequential MV group, the incidence of ventilator-associated pneumonia (VAP) was significantly decreased [27.3%(12/44) vs. 55.3% (26/47),χ2 = 7.350,P = 0.007], and the rate of ETI≥2 times was increased [59.1% (26/44) vs. 29.8% (14/47),χ2 = 5.095,P = 0.024] as compared with conventional MV group. Compared with survival group, the patients in non-survival group showed a higher incidence of cerebrovascular disease (60.7% vs. 25.4%,P = 0.002), higher acute physiology and chronic health evaluationⅡ (APACHEⅡ) score (26.46±2.59 vs. 24.41±2.47,P = 0.001), British Thoracic Society confusion, uremia, respiratory rate, blood pressure,≥75 years (CURB-75 score, 4.00±0.47 vs. 3.68±0.53,P = 0.013), a longer total duration of MV (days: 21.18±10.02 vs. 14.56±7.62,P = 0.002), and a higher ratio of ETI≥ 2 times (53.6% vs. 33.3%,P< 0.001). It was revealed by multivariate logistic regression analysis that ETI≥ 2 times and comorbidity of cerebrovascular infarction were independent predictors of a worse outcome in the senile patients [odds ratio (OR) = 9.677, 95% confidence interval (95%CI) = 3.075 - 30.457,P< 0.001;OR = 5.386, 95%CI = 1.781 - 6.284,P = 0.003]. It was showed by Kaplan-Meir survival analysis that ETI times and concurrent cerebrovascular infarction imparted significant effects on the 60-day survival rate (χ2 = 40.805,P= 0.000;χ2 = 4.425, P = 0.035).ConclusionInvasive-noninvasive sequential MV may not improve the outcome of senile patients with severe CAP, and ETI≥ 2 times and concurrent cerebrovascular disorders drastically lowered the survival rate.

Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.

Objective To investigate the value of global longitudinal strain (GLS) in detecting severe coronary artery stenosis (SCAS) in patients with coronary artery disease. Methods Fourty-two patients with SCAS confirmed with coronary arteriongraphy (CAG) underwent two-dimensional strain echocardiography. GLS, wall motion score index (WMSI) and left ventricular ejection fraction (LVEF) were obtained. Taking CAG as gold standard, the sensitivity, specificity and areas under the ROC curve (AUC) of definition of SCAS with GLS, WMSI and LVEF were calculated, respectively. Fifteen healthy volunteers were recruited as control. Results ①Definition of one or more branches with severe stenosis: The sensitivity and specificity was 77.51% and 100% with GLS of -17.50% as a cutoff value, 70.01% and 100% with WMSI of 1.00, and 57.51% and 100% with LVEF of 59.21%. ②Definition of two or more than two branches with severe stenosis: The sensitivity and specificity was 62.52% and 80.81% with GLS of -11.05% as a cutoff value, 56.22% and 65.31% with WMSI of 1.60 and 56.21% and 65.42% with LVEF of 54.31%. ③The correlation coefficient was 0.78 between GLS and LVEF, and -0.82 between WMSI and LVEF. The AUC of detecting one or more branch with severe stenosis with GLS, WMIS and LVEF was 0.87, 0.80 and 0.78, respectively, and AUC of GLS was more than that of LVEF (P＜0.01). AUC of detecting two or more than two branches with severe stenosis with GLS, WMIS and LVEF was 0.76, 0.64 and 0.64, AUC of GLS was more than that of LVEF and WMSI (all P＜0.01). Conclusion GLS can be used in detecting SCAS, and the value of GLS is better than that of WMIS and LVEF.

OBJECTIVE:To investigate the effects of Qigong pills decoction combined with chemical drugs on hormone levels of polycystic ovarian syndrome(PCOS)patients complicated with infertility. METHODS:A total of 98 PCOS patients complicated with infertility selected from gynaecology department of our hospital during Jul. 2015-Jun. 2016 were divided into observation group and control group according to random number table,with 49 cases in each group. Control group was given Clomiphene ci-trate tablet 50 mg orally,qd,for consecutive 5 d;B-ultrasonography for follicle development was monitored at the 11th day of menstruation,and then they were given Chorionic Gonadotropin for injection 2000 U intramuscularly,qod,if there was not domi-nant follicle >10 mm till the diameter of follicle reached 18 mm. Observation group was additionally given one dose of Qigong pills decoction,every day 400 mL after decocted with water,each 200 mL for morning and night,on the basis of control group. After 3 months of treatment,the levels of FSH,LH,PRL,E2,T,DHEA-S and SHBG,the endometrial thickness,the number of mature follicle and pregnancy rate were compared between 2 groups. RESULTS:Before treatment,there was no statistical signifi-cance in the levels of FSH,LH,PRL,E2,T,DHEA-S or SHBG between 2 groups(P>0.05). 3 months after treatment,the lev-els of PRL,T and DHEA-S in 2 groups were decreased and E2,SHBG were increased significantly;the levels of FSH,PRL,T and DHEA-S in observation group were significantly lower than control group,while the levels of E2 and SHBG were significantly higher than control group,with statistical significance (P<0.05). Endometrial thickness of observation group were significantly higher than that of control group;pregnancy rate (18.37%) was significantly higher than control group (4.08%),with statistical significance (P<0.05). CONCLUSIONS:Qigong pills decoction combined with chemical drugs can help to improve pregnancy rate and regulate serum hormone level in the treatment of PCOS complicated with infertility.

The effect of anisodine on brain monoamine was studied in 30 rats. The brain monoamine levels of caudate nucleus, hippocampus, diencephalon, brain stem and cerebral cortex were estimated by fluoro-metric method in drug-treated rats and saline-treated controls. Only the NE level of the brain stem was significantly increased in anisodine-treated animals 48 hours after injection. There were no significant differences in the dopamine values between anisodine-treated rats and saline-treated controls, while the 5HT and 5HIAA levels were significantly increased in anisodine-treated animals. The relation of brain monoamines to learning and memory is discussed. The increased 5HT and 5HIAA levels caused by anisodine may play a role in the impairment of memory.

Objective Henoch-Sch?nlein purpura(HSP)is a common multisystemic vasculitis in children ,but the exact pathogenesis remains unknown. Pentraxin 3(PTX3),a new kind of inflammatory cytokines,has a strong inflammatory effect,and is involved in occurrence and develop-ment of a variety of autoimmune diseases. The objective of this study is to evaluate the expression of PTX3,interleukin-8(IL-8),tumor necrosis fac-tor-α(TNF-α)and high sensitivity C-reactive protein(hs-CRP)in children with HSP,and explore the clinical significance of PTX3 in HSP devel-opment. Methods Thirty-six children(HSP group)and 17 healthy children(control group)were enrolled in the study. Serum levels of PTX3,IL-8 and TNF-α were detected by enzyme-linked immunosorbent assay. Serum hs-CRP levels were measured by automatic biochemical analyzer. Re-sults The serum levels of PTX3,IL-8,TNF-α,and hs-CRP were up-regulated in HSP group compared with the control group(P<0.05). The levels of PTX3,IL-8,TNF-α,and hs-CRP in patients with joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury were significant-ly higher than those patients without joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury(P<0.05). The expression of PTX3 was positively correlated with the expression of IL-8 and TNF-α(r=0.514,0.833,all P<0.05),but there was no correlation between PTX3 and hs-CRP(r=0.292,P>0.05). The expression of PTX3,IL-8,TNF-α and hs-CRP in HSP patients had no gender difference(all P>0.05). Con-clusion The high expression of PTX3 is related to the degree of inflammation in children with HSP. The up-regulated expression of PTX3 may play an important role in pathogenesis of HSP in children.

Objective To investigate the relationship between phosphatidylinositol 3-kinase catalytic subunit α(PIK3CA) expression and the incidence and different pathological grade of gastric cancer, and the mechanism thereof. Meth-ods The expressions of PIK3CA, serine/threonine protein kinase (pAkt) and cell proliferation associated nuclear antigen (ki-67) in gastric carcinoma and adjacent tissues and normal gastric mucosa were detected by immunohistochemical method. The relationship between expressions of PIK3CA, pAkt and ki-67 and tumorigenesis was analyzed. The expressions of PIK3CA, pAkt and ki-67 in different pathological conditions of gastric tissues were analyzed. The relationship between tu-mor pathologic classification and differentiation were analyzed too. Results There were significantly higher expressions of PIK3CA, pAkt and ki-67 in gastric cancer (P＜0.05), which were the highest in the poorly differentiated gastric adenocarci-noma (P＜0.05). There were a positive correlation between expressions of PIK3CA, pAkt and ki-67 and different pathologi-cal levels of gastric carcinoma and adjacent tissues and normal gastric tissues (P＜0.05). Conclusion PIK3CA may be the initiating factor of PI3K/Akt signaling pathway, which induced phosphorylation of Akt and activation PI3K/Akt signaling pathway, promoting the proliferation, invasion and metastasis of gastric adenocarcinoma.
