Objective To explore the risk factors of the chronic subdural hematoma(CSDH) drilling drainage recurrence.Methods The clinical data of 252 CSDH patients were retrospectively analyzed.All patients underwent trephination and drainage treatment,there were 40 cases with postoperative recurrence of hematoma.Multivariate logistic analysis of linear regression was used to analyze the risk factors for postoperative hematoma recurrence.Results In this study,of 252 CSDH patients received trepanation and hematoma,the probability of recurrence was 15.9 ％ (40/252).Single factor analysis showed that the size of hematoma,CT shows the density of hematoma,postoperative drainage volume,operation time,review the CT intracranial pneumatosis,age,hematoma midline shift could increase the recurrence possibility.Logistic multivariate analysis showed that he size of hematoma,CT shows the density of hematoma,postoperative drainage volume,age were independent risk factors of recurrence of hematoma drainage in patients with CSDH after drilling.Conclusion The influence factor of recurrence of hematoma in CSDH patients received trepanation and drainage is complex,we should strengthen the intraoperative,postoperative nursing and operation to reduce postoperative recurrence of CSDH.

Objective To investigate the expressions of microRNA-21,microRNA-143,and microRNA-145 in the sera of patients with nasopharyngeal carcinoma (NPC),and their assessment vales in the recurrence,metastasis,and prognosis of NPC patients.Methods From January 2012 to January 2014,80 NPC patients in our hospital Department of Internal Medicine and Head and Neck Surgery was used as tumor group,80 cases of healthy volunteers as control.The real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the expression levels of microRNA-21,microRNA-143,and microRNA-145 in the sera.Results Expression of microRNA-21 in NPC patients was significantly higher than that in healthy control group with statistically significant difference (P ＜ 0.05).The expressions of microRNA-143 and microRNA-145 in NPC patients was significantly lower than those in healthy control group with significant difference (P ＜ 0.05).At the same time,those microRNAs were significantly associated with tissue differentiation,invasion,and metastasis.Conclusions Increased microRNA-21 expression level in NPC patients,and decreased expression of microRNA-143 and microRNA-145 in NPC patients play an important role in differentiation,invasion,and metastasis in the development process of NPC.microRNAs can be used as a new index in the auxiliary diagnosis of NPC and the evaluation of recurrence,metastasis,and prognosis evaluation.

Objective To explore the relevance of high density lipoprotein cholesterol (HDL-C) level and resistance of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in advanced non-small cell lung cancer (NSCLC).Methods In a total of 87 NSCLC patients harboring EGFR mutation treated with EGFR-TKI, the correlations of pre-treatment levels of soluble HDL-C between efficacy and resistance of EGFR-TKI were analyzed by Kaplan-Meier method and Cox proportional hazard model.Results Patients with normal HDL-C (≥0.94 mmol/L) had a better disease control rate (DCR) than those with low HDL-C (＜0.94 mmol/L) [94.5 ％ (52/55) vs 65.7 ％ (21/32), P ＜ 0.001].The results of univariate analysis showed that patients with normal HDL-C had longer progress free survival (PFS) (HR =0.27, 95 ％ CI 0.164-0.444, P ＜ 0.001).The results of multivariate Cox proportional hazard model analysis with sex, pathologic histology, smoking history and mutation type showed that only HDL-C group had a significant difference (P ＜ 0.001).The same results were showed when stratified by sex and smoking history (female: P ＜ 0.001, male: P =0.002;Smoker: P ＜ 0.001, non-smoker: P =0.014).Conclusion Normal pre-treatment serum levels of HDL-C are associated with a better outcome and longer progression-free survival in NSCLC patients treated with EGFR-TKI, which may be a predictive marker for a better response.

Objective To investigate the impact of rivaroxaban and low molecular weight heparin on hidden blood loss after unilateral first half artificial hip replacement surgery.Methods According to the digital table,a total of 80 cases because of femoral neck fractures in elderly patients with unilateral arthroplasty artificial hip and a half after surgery were randomly divided into the rivaroxaban group and low molecular weight heparin (LMWH) group,40 cases in each group.In both groups,respectively,after 12 h begin daily oral rivaroxaban 10 mg and subcutaneous low molecular weight heparin 5 000 u,compared the two groups around the actual amount of perioperative blood loss,blood loss was dominant,recessive blood loss and hidden blood loss accounts,the actual percentage of total blood loss,and recorded 35d bleeding events.Results The total amount of blood loss,dominant blood loss,hidden blood loss and the hidden blood loss accounted for the actual percentage of the total amount of blood loss of the rivaroxaban group were (671.00 ± 55.61) mL,(313.88 ± 14.53) mL,(350.00 ± 29.41) mL,(52.00 ± 5.22) ％,respectively,which of the the LMWH group were (662.00 ± 30.19) mL,(288.87 ± 15.33) mL,(372.00 ± 35.10) mL,(56.00 ± 6.71) ％,there were no significant differences between the two groups (t =0.93,0.93,0.83,1.03,all P ＞ 0.05).Conclusion For patients first underwent unilateral hip replacement surgery artificial half,perioperative using rivaroxaban or LMWH has no significantly differences in hidden risk of bleeding and bleeding event rate.

Objective To investigate the effects of dexmedetomidine pretreatment on lung injury for patients after liver surgery. Meth-ods Sixty patients who had liver surgery in our hospital from August 2009 to February 2014 were equally divided into the treatment group and the control group, with 30 patients in each group. Both of the two groups were given one-lung ventilation anesthesia. Patients in the treatment group were given continuous intravenous infusion of dexmedetomidine after induction of anesthesia while paitents in the control group were not. In the time of before induction of anesthesia (T0), closed chest (T1), immediately after surgery (T2), all patients were given the gas analysis, expression of inflammatory cytokines and lung function testing and analysis. Results The diastolic blood pressure and heart rate at time points of T0, T1 and T2 in the two groups showed no significant difference (P> 0. 05). And the expression of TNF-αand SP-D at time points of T1 and T2 in the two groups were significantly higher than those at T0 (P<0. 05);while the expression of TNF-αand SP-D in the treatment group were significantly lower than those in the control group at time points of T1 and T2 (P<0. 05). The plateau air-way pressure and airway resistance in the treatment group at T2 and T3 were significantly lower than that at T1 (P<0. 05), and there were statistically significant differences compared with the control group (P<0. 05). Conclusion The dexmedetomidine pretreatment for the liver surgery patients can inhibit the inflammatory response, while improve lung airway plateau pressure and airway resistance. It has no significant effect for blood, so it can play a protective role for lung function.
