OBJECTIVE:To observe clinical efficacy and safety of tanshinone ⅡA sulfonate combined with alprostadil in the treatment of acute cerebral infarction. METHODS:56 patients with acute cerebral infarction were randomly divided into treatment group(36 cases)and control group(20 cases). Control group was given tanshinone ⅡA sulfonate 60 mg intravenously,qd,for 10 days. Treatment was additionally given Alprostadil injection 10 μg intravenously,30 min drop lrote,qd,the two group for 10 days,on the basis of control group. Therapeutic efficacy and BI were observed at the end of a treatment course. RESULTS:The ef-fective rate of treatment group and control group were 91.67% and 75.00%,with statistical significance(P<0.05). BI score of 2 groups after treatment were better than before,and the treatment group was better than the control group after treatment,with statis-tical significance (P<0.05). No obvious ADR wad found in both groups. CONCLUSIONS:Tanshinone ⅡA sulfonate combined with alprostadil is effective in the treatment of acute cerebral infarction with good safety.

There is a high prevalence of gastric cancer in China,but most of the patients are diagnosed at advanced stages,when chemotherapy is regarded as an important component of the multimodal treatment.Chemotherapy has demonstrated advantages over best suppor-tive care in prolonging survival and improving quality of life.Over the past 40 years,the clinical responses of two or three-drug combination chemotherapy regimens have been accepted,and 5-fluorouracil,cisplatin and epirubicin have been most frequently used in gastric cancer.Recently,the therapeutic effects of advanced gastric cancer treated by new regimen consisted of docetaxel,irinotecan,oxaliplatin and capecitabine have been further enhanced.The molecular targeted agent,cetuximab and bevacizumab,combined with chemotherapy,would be more promising therapeutic regimens in the treatment of advanced gastric caner.

Objective To investigate the effects of flurbiprofen axetil for preemptive analgesia on hemodynamics and stress levels in patients undergoing neurosurgery.Methods 60 patients undergoing neturosurgery were enrolled in the study.The patients were randomly divided into the flurbiprofen group (Group F,n =30) or the control group (Group C,n =30).HR,MAP and serum norepinephrine (NE),epinephrine (E) levels were measured at 30min before the end of operation (T0),immediately after the end of operation (T1),immediately after extubation (T2).Results The changes in MAP,HR and serum NE,E levels in Group F at T1 and T2 were less than those of Group C (all P ＜ 0.0 1).Conclusion Flurbiprofen axetil for preemptive analgesia may suppress the stress response during recovery period in neurosurgical patients,and keep the hemodynamic index stable.

Objective To evaluate the influence of dexmedetomidine（Dex） on sedation and requirement of propofol during anesthesia induction. Methods Thirty patients（ASA Ⅰ or Ⅱ） undergoing selective operation were randomly divided into 2 groups：Dexmedetomidine group （group D,n=15） or control group （group C,n=15）. Patients in the group D received 1 μg/kg dex diluted to 10ml over 10 min by pumped infusion and patients in the group C was simply recieved normol saline at the same way.Twenty minutes after administrating the drug,patients in both groups were pumped propofol at the speed of 0.4 mg·kg-1·min-1. When holding up jaw without movement,patients received 1 μg/kg fentanyl and 0.6 mg/kg rocuronium,and endotracheal intubated 1.5 minutes later. RE,SE,Ramsay sedation scale of the patients were recorded before（T0） and after 5,10,20 minutes（T1-T3） of drug adminstration.The minimum dose and total dose of propofol during induction were recorded.Results Compared with group C and T0,RE and SE in group D decreased obviously at T1-T3 （P0.01）,while Ramsay sedation scale rised significantly （P0.01）. Compared with group C,the minimum dose and the total dose of propofol decreased obviously in group D during induction （P0.01）.Conclusion Dexmedetomidine causes sadetive without respiratory depression,and has the propofol sparing effect during anesthesia induction.

Background Epithelial-mesenchymaltransition (EMT)isamajorcontributortothe pathogenesis of posterior capsular opacification(PCO).Kruppel-like factor 6 (KLF6) is a zinc finger protein,which can be stimulated by high glucose in proximal tubule cells and involved in transforming growth factor beta (TGF-β)induced EMT of diabetic nephropathy.ObjectiveThis study was designed to investigate the effect of high glucose on the expression of KLF6 and its target genes( TGFB1,TGFBR1,COLIA1,HSP47) in human lens epithelial cells (LECs).MethodsHuman LECs(SRA01/04) were cultured and exposed to different concentration of glucose.The expressions of KLF6 mRNA and protein were analyzed by real time polymerase chain reaction( real time PCR) and western blot after treatment with high glucose.The expressions of KLF6 target genes were analyzed by real time PCR to evaluate the EMT of SRA01/04 cells.ResultsCompared with the control group(5.5 mmol/L),the relative mRNA levels of t-KLF6 and wt-KLF6 in SRA01/04 treated with high glucose(22.2,44.4,66.6 mmol/L) increased obviously (F =72.53,42.02,P＜0.01 ).Then,the concentration of 22.2 mmol/L was used in the next experiments.The relative mRNA levels of t-KLF6 and wt-KLF6 increased to the peaks after treatment with high glucose for 12 h,and began to decrease after 24 h until lower levels after 48 h ( F =100.12,125.52,P ＜ 0.01 ).Western blot showed that the expression of KLF6 protein was also upregulated by high glucose treatment.With the promotion of the expression of KLF6 gene,the relative mRNA levels of TGFB1,TGFBR1,COLlAl and HSP47 of treated cells also respectively increased after treatment for 12 h,and began to decrease after 24 h until nearly at the levels of the control groups after 48 h( F=6.73,162.35,64.39,12.05,P＜0.05 ).ConclusionsIt was concluded that high glucose induced the expression of KLF6 in human LECs,and KLF6 transiently stimulated the expression of target genes TGFB1,TGFBRl,COLlAl and HSP47 which were mainly involved in the mechanism of EMT.

Free fatty acids generated from the metabolites of fat have been demonstrated to stimulate the neutrophils to produce reactive oxygen species ( ROS) such as hydrogen peroxide and chlorous peroxide .It has shown that free fatty acid is closely related with myocardial, vascular endothelium, liver, lung and other tissue damage.The mechanism of erythrocyte injury is oxidation of mem-brane polyunsaturated fatty acids and cytosolic hemoglobin by ROS .High levels of free fatty acids can increase the formation of active reaction molecular ROS , thus initiating the oxidative stress reaction .Active molecules can oxalate and damage the DNA , protein, lipid and other molecules of RBC .It has revealed the relationship between free fatty acids and erythrocytes injury , which provided a new di-rection in the research of oxidative anemia .This article reviews the advances in the research of this subject in recent years .

Objective To analyze the demographic characteristics,composition characteristics as well as influencing factors of the cost of hospitalization of patients with lung cancer in Gansu Province in order to help reduce their expenses. Methods The basics,healthcare records and expenses of patients diagnosed with lung cancer in a third-level grade-A hospital in Lanzhou were extracted between 2010 and 2014 through the hospital information system(HIS)database.The Wilcoxon rank-sum test was used to analyze the difference of expense composition over the past five years and the difference between subgroups.The forward,backward and stepwise selection method was used to select variables and the multi-linear regression analysis was adopted to explore the influencing factors of the cost of hospitalization.Results A total of 2778 eligible lung cancer patients were collected.The statistical analysis showed that western medicine cost (36.39%)and treatment cost (22.46%)accounted for the most of the total expense.The length of hospital stay was the No.1 influencing factor of the cost of hospitalization,followed by the acceptance of surgery,the year of admission and charge type. Conclusion Regulating drug use,enhancing treatment regimens,giving psychological guidance,strengthening hospital management and improving medical resources allocation may be effective measures to reduce the cost of hospitalization and lighten the economic burden for lung cancer patients in Gansu Province.
