Several models about epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKI)as first-line treatment in advanced NSCLC show different results.Combination with chemotherapy and EG-FR-TKIs did not indicate survival advantage.However,sequential chemotherapy in EGFR-TKIs and a single agent of EGFR-TKIs as first-line treatment of advanced NSCLC have made tremendous breakthrough,and give a new path in individual treatment of advanced NSCLC.Also EGFR mulatious in targeted therapy of advanced NSCLc has a sood predictive value of the etticacy.

Far beyond simulating manual work with the computer system,hospital informatization entails a combination of information technology with hospital professional work.With a fully understanding of working procedure in hospital,an effective concordance based on informatization requirements is conducted so that the management and the collection of the information can follow the information flow,logistics,capital flow,working flow and organization flow.Management mode and organization framework of the hospital are also adjusted.Thus the hospital operation quality and efficiency are improved,and patients are offered seamless and continuous service,which really reflects the service theory: "Patient First".

AIM: To develop a method of determining notoginsenoside R_1,ginsenoside Rg_1 and ginsenoside Rb_1 in Naomaitai Capsules(Radix et Rhizoma Ginseng Rubra,Radix et Rhizoma Notoginseng,Radix Angelicae Sinensis,etc.) by HPLC. METHODS: Notoginsenoside R_1,ginsenoside Rg_1 and ginsenoside Rb_1 were determined by HPLC gradient elution method,Inertsil-ODS-3(5 ?m 4.6 mm?250 mm) column with Acetonitrile-water as the mobile phase was used for gradient elution.The flow rate was at 1.0 mL/min and the detective wavelength was at 203 nm.The column temperature was at 35 ℃. RESULTS: There was a good linear relationship at a range of 0.205-1.539 ?g for notoginsenoside R_1(r=0.999 6),the average recovery of 98.07%, and RSD of 0.51%(n=5),0.838-6.285 ?g for ginsenoside Rg_1(r=0.999 4),the average recovery of 97.66%,and RSD of(0.53%)(n=5),0.822-6.165 ?g for ginsenoside Rb_1(r=0.999 6),the average recovery of 98.19%,and RSD of 0.44%(n=5). CONCLUSION: The method is simple,reproducible and accurate with a strong specificify,and can be used for the quality control of Naomaitai Capsules.

METHODS:Folium Isatidis,Radix et Rhizoma Rhei,menthol in Qinghuo Tablets were identified by TLC.Indirubin and emodin were determined by HPLC.Agilent-ODS-3(5 ?m,4.6 mm?250 mm) column was used.The column temperature was at 25 ℃.Methanol-0.5% H_3PO_4(75∶25) was used as a mobile phase.The detection wavelength was at 289 nm.The flow rate was 1.0 mL/min. RESULTS:Folium Isatidis,Radix et Rhizoma Rhei,menthol could be detected by TLC.Indirubin showed a good linear relationship at the range of 0.071 4-0.714 ?g,r=0.999 7.The average recovery was 98.95%,and RSD was 0.57%.Emodin showed a good linear relationship at the range of 0.204-2.04 ?g,r=0.999 8.The average recovery was(99.01%),and RSD was 0.79%. CONCLUSION:The established method is rapid,accurate,reproducible with a strong specificify.

Objective To explore the relationship between heart rate variability(HRV)and serum high sensitivity C-reactive protein(hs-CRP)in type 2 diabetic aged patients.Methods Totally 30 aged patients with type 2 DM were enrolled in this study who were selected from the outpatients and inpatients of Department of Gerontology in the Third People's Hospital of Chongqing,and another 30 non-diabetic matched individuals were recruited as control.Their serum hs-CRP and 24 hour-electrocardiography were examined.HRV was assessed by calculating the indices based on statistical operation on RR intervals(time domain analysis)from 24-hour Holter recording,including:standard deviation of normal to normal RR intervals(SDNN),standard deviation of 5-minute mean RR intervals(SDANN)and square root of differences between adjacent NN intervals(rMSSD).Linear correlation analysis was carried out between their serum hs-CRP and HRV.Results HRV parameters of type 2 DM patients were significantly lower than those of non-diabetic patients,but hs-CRP values were significantly higher than those of control.Linear correlation analysis indicated that HRV was in a positive correlation with hs-CRP in type 2 diabetic aged patients.Conclusion Altered autonomic nervous function may be associated with altered serum hs-CRP in aged patients with type 2 diabetes mellitus.

A backup data center near the primary data center using Storage Area Network is built with Fiber Channel technology. The specific disaster recovery software used to synchronize the two centers a highly reliable safety and expandable data storage management system with adequate redundancy is developed. Thus disaster recovery service can be provided for the hospital information system when disaster happens. To avoid the system risk and maintain the continuity of the hospital's activities the damaged part of the system will be taken over from.

Objective To investigate the characteristics of risk factors and coronary angiography (CAG)in young patients with acute myocardial infarction(AMI).Methods A total of 36 consecutive AMI female patients (age≤44 years)who underwent coronary angiography were retrospectively retrieved from the database,and 90 AMI patients whose age >44 years who also underwent coronary angiography were enrolled as a control (elderly)group.Characteristics of risk factors and coronary angiography were com-pared between the two groups.Results The risk factors:BMI,family history of coronary heart disease and high triglycerides(TG)were major in the youth group.The percentage of single-branch lesion was lower in the young patients.The prevalence of left anterior descending (LAD)was higher in the young patients(P <0.05).Conclusions The main risk factors in young and elderly patients are significantly different.The out-comes of CAG in the young patients show the coronary lesion are mostly single vessel lesion,and early inter-vention may improve prognosis.

Objective To observe the nursing effect of closed needle-free style injection connector in endoscopic nasobiliary drainage (ERCP). Methods From June 2013 to June 2014, 400 patients of the common bile duct stones underwent ERCP technique and placed nasobiliary were divided into two groups according to chronological. Between June 1st, 2013 and December 20th, 200 patients were set as control group, between December 21th, 2013 and June 30, 2014, 200 patients were set as experimental group. For the control group, the nasobiliary duct was directedly connected to the disposable drainage bag. For the experimental group, the nasobiliary duct was connected to closed needle-free style injection connector, and then to the drainage bag. The incidences of the detached connection, the fracture of the connection with the nasobiliary duct, bile leakage from the connection, and post-ERCP infection were compared between two groups. Results The incidence of bile leakage, crack pipes, separation and postoperative infection occurred at the junction nasobiliary rates in the experimental group were 0,0,0,2%(4/200), which were far lower than 35% (70/200),11% (22/200), 6% (12/200), 6%(12/200) of the control group. The difference was statistically significant (χ2=31.75~169.60, P < 0.01). Conclusions The application of closed needle-free style injection connector can effectively avoid the detachment and fracture of the connection, the occurrence of bile leakage, and post-ERCP infection. This will be helpful to decrease the burden of nursing care and increase patients′satisficationdegree.

Objective To investigate the clinical intervention effect of superficial needling at point Fenglong on gastroscopy side reaction.Methods Eighty-two gastroscopy patients were randomly allocated to treatment and control groups, 40 cases each. The treatment group received gastroscopy and superficial needling at point Fenglong, and the control group, gastroscopy and sham acupuncture at point Fenglong. The pain score and the incidence of nausea and vomiting were observed in the two groups during gastroscopy.Results There was a statistically significant difference in the pain score between the two groups (P<0.05). The incidence of nausea and vomiting was 31.7% in the treatment group and 65.9% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Superficial needling at point Fenglong can effectively reduce the incidence of gastroscopy side reaction.
