OBJECTIVE To study the distribution and drug resistance of the cancer patient′s pathogenic bacteria.METHODS The clinical nosocomial infection of 1451 cancer patients was analyzed by using the soft WHONET-5.RESULTS Of 955 strains isolated from sputa,the G-bacilli were 31.2%,and their main bacteria were Pseudomonas aeruginosa and Klebsiell pneumoniae,the G+ coccis were 31.2%,and their main bacteria were Staphylococcus epidermidis,and the fungi were 43.3%,and their main molds were Candida.albicans.Of 284 strains isolated form stool,the G-bacilli were 64.4%,and their main bacteria were Eschericha coli,the G+ cocci were 10.2% and their main bacteria were S.epidermidis,and fungi were 25.5%.Of 72 strains isolated from blood,the G-bacilli were 62.5%,and their main bacteria were E.coli,the G+ cocci were 30.5% and the fungi were 7.0%.Of 140 strains isolated from pharyngeal swab,the G-bacilli were 15.0%,and the G+ cocci were 43.0% and the fungi were 42.0%.The results of sensitivity tests showed as followed: The G-bacilli had a highly sensitive to imipenem,and had a high drug resistance against the first and second generation cephalosporin,ampicillin,piperacillin.The G+ cocci were highly sensitive to vancomycin and had a high drug resistance against oxacillin,penicillin,and erythromycio,the fungi had an obvious drug resistance against azoles.CONCLUSIONS It is high prevalence of ESBLs among MRS,and Staphylococcus.The application and selection of antibiotics must be based on the results of sensitivity tests,and the drug resistance of pathogenic bacteria must be controlled.

Background and purpose:New treatment strategies should be explored for non-small cell lung cancer (NSCLC) patients after the failure of the epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). To compare the efficacy and toxicities of chemotherapy in combination with EGFR-TKI or single chemotherapy in advanced NSCLC patients with EGFR-TKI resistence. Methods:In this study, 18 patients were enrolled. Eight patients were treated by chemotherapy combined with EGFR-TKI (CE group);10 patients were treated by single chemotherapy (E group), 21 days for one cycle. All patients received at least 2 cycles of treatment. Results:All 18 patients had been evaluated. The CE group was similar to the E group in objective response rate (ORR:25%vs 10%, P=0.832). The CE group was higher than the E group in disease control rate (DCR:87.5%vs 30%, P=0.046). The median PFS was longer in CE group (3.5 months vs 2.4 months, P=0.05). The CE group was higher than the E group in rash (75%vs 10%, P<0.05). The grade 3-4 toxicities did not have significantly differences between the two groups (P>0.05). Conclusion:Though there was no significant difference in ORR between the 2 groups (P>0.05), the CE group was superior to the E group in DCR and PFS. Patients with retreatment of advanced NSCLC after the failure of EGFR-TKI can be controlled by continued EGFR-TKI and chemotherapy.

Objective To investigate the incidence of sub-health fatigue among medical workers exposing to radioactive rays, and to observe the therapeutic effect of Bushen Jianpi recipe on sub-health fatigue. Methods An investigation was carried out among 1 056 medical workers exposing to radioactive rays which were from the medical and sanitary institutions of Guangzhou city. Sixty cases subjecting to the inclusion criteria were sampled from the investigated population by epidemiological methods for the randomized controlled trial. The subjects were evenly randomized into treatment group and control group. Both groups received health education and health-promoting lifestyle, and the treatment group was given self-prescribed Bushen Jianpi recipe additionally. The treatment lasted for 4 weeks. The scores of Multidimensional Fatigue Inventory ( MFI-20) and Sub-health Measurement Scale Version 1.0 ( SHMS V1.0) were observed before and after treatment, and the therapeutic effect was evaluated after treatment. Results ( 1) We got 976 effective questionnaires, and the effective response rate was 92.4%. Among the admitted 976 workers, the incidence of sub-health state was 66.8% (652/976) and that of sub-health fatigue is 31.4% ( 205/976). ( 2) The total effective rate was 80.0% in the treatment group and was 36.7% in the control group, the difference being significant ( P<0.01). ( 3) After treatment, the scores of MFI-20 and SHMS V1.0 were decreased in the treatmeat group, and fatigue symptom scores were decreased in the control group ( P<0.05 or P<0.01) , the decrease in the treatment group being superior to that in the control group ( P<0.05 or P<0.01). Conclusion The incidence of sub-health fatigue is popular in the medical workers exposing to radioactive rays, and Bushen Jianpi recipe has an effect on improving the sub-health fatigue.

The upper limb motor function of two groups was evaluated by Fugl-Meyer Assessment (FMA) before and after treatment.ResultsAfter 28 days treatment, scores of FMA of two groups were all raised significantly, but it was significantly greater for the treatment group than the control group (P<0.01).ConclusionIt is shown that acupuncture combined with training of the rehabilitation apparatus can improve the upper limb motor function and activity of daily living of patients with ischemic stroke.

Objective To analyze the surgical technique of extraperitoneal laparoseopic radical prostatectomy with neurovascular bundle preservation and its effect on micturition control and sexual function in patients with prostate cancer. Methods Twenty-two patients with a median age of 66. 9 years underwent extraperitoneal laparoscopic radical prostatectomy with neurovascular bundle preservation from October 2005 to March 2009 in our hospital and Shanghai Changzheng hospital. All patients had no erectile dysfunction. According to the pathology, there were 2 cases of PIN high grade, 4 cases of Tla-b, 9 cases of Tlc, 4 cases of T2a-b, 2 cases of T2e and 1 case of T3a. Results All operation were successful and no case was conversed to open surgery. The average operation time was 225 min and the mean blood loss was 850ml. The amount of blood loss in 1 case was 1200 ml because of injuring deep dorsal vein of penis. 4 cases received blood transfusion, gatheters of all patients were removed 2 weeks after operation, and three cases with mild incontinence regained continence of urine after 6 months follow-up. No patient occurred postoperative vesicourethral anastomotic leakage of urine. The surgical margin of 1 case was positive. No biochemical index of prostatl cancer recurred during postoperative follow-up of 10-24 months (with an average of 16 months). 20 cases had sexual function recovery after operation. Conclusions The extraperitoneal laparoscopie radical prostatectomy with neurovascular bundle preservation for prostate cancer is a safe and effective treatment method with less bleeding, small damage and less complications. It can guarantee the maximum of micturition control and sexual function, which is worthy to be popularized in the clinic.

Objective To investigate the anesthetic effect and adverse events on different doses of oxyco-done combined with propofol target controlled infusion(TCI)in patients with choledocholithiasis undergoing endo-scopic retrograde cholangio pancreatography(ERCP)with endoscopic sphincterotomy(EST).Methods One hun-dred and twenty patients with choledocholithiasis underwent ERCP with EST in Department of Gastroenterology, Fuzhou General Hospital,from January,2016 to March,2017 were enrolled in this study.Patients were randomly divided into 4 groups(n=30 in each group)including the sufentanil control group(Group A),low dose of oxyco-done group(Group B),moderate dose of oxycodone group(Group C),and high dose of oxycodone group(Group D).Patients in Group A received 0.10 μg/kg intravenous sufentanil,and patients in Group B,C,and D received 0.08 mg/kg,0.10 mg/kg,and 0.12 mg/kg intravenous oxycodone,respectively,at 5 min before induction of gener-al anesthesia followed by propofol TCI. Effect of compartment concentration(Ce)of propofol,mean arterial pres-sure(MAP),and heart rate(HR)at the given time point when patients transferring to operation room(T0),after induction(T1),endoscope through throat(T2),and endoscope through major duodenal papilla(T3)were record-ed.The accumulative dose of propofol,duration of operation,and recovery time were also recorded.Intraoperative sever hypotension,bradycardia,respiratory depression,coughing and moving,and postoperative nausea and vom-iting were recorded. Results Propofol Ce at T1~T3as well as MAP and HR at T2and T3in Group B were signifi-cantly higher than those in Group A,C,and D,respectively(P < 0.05). The accumulative dose of propofol in Group B was more than that in Group A and C,while the accumulative dose of propofol in Group D was less than that in Group A,B,and C,respectively(P<0.01).Recovery time in Group D was longer than that in Group A, B,and C,respectively(P<0.05).Similar incidences of intraoperative sever hypotension,bradycardia,respiratory depression,coughing and moving,and postoperative nausea and vomiting were also observed. Conclusions 0.10 mg/kg intravenous oxycodone at 5 min before induction of general anesthesia combined with propofol TCI presents a favorable anesthetic effect in patients with choledocholithiasis undergoing ERCP with EST without a prolonged recovery time and the increased incidence of adverse events.

Objective To evaluate the relationship between birth weight and nonalcoholic fatty liver diseases (NAFLD) in Chinese primary school students. Methods A cross-section study was conducted in ifve elementary schools in Gao Hang Town, Shanghai and 2163 students were enrolled in the study (1120 boys/1043 girls). Height, body weight, waist circumference and per-cent of body fat (bioelectrical impedance analysis) were measured by professional nutritionist after training. Birth weight, feeding pattern, height and body weight of parents were obtained by a self-completed questionnaire. NAFLD was diagnosed by ultra-sound. The risk factors of NAFLD were analyzed. Results The prevalence of NAFLD in the study population was 8.9%. The prevalence of NAFLD was signiifcantly higher in boys than that in girls (12.5%vs 5.0%, P<0.01). Logistic regression showed that sex (OR=1.97, 95%CI:1.21-3.21) and percent of body fat (OR=1.12, 95%CI:1.07-1.17) were the risk factors of NAFLD, and normal BMI was the protective factor of NAFLD (OR=0.09, 95%CI:0.04-0.19) in the study population. Conclusions The pre-valence of NAFLD is higher in boys than that in girls. Also overweight, and high percent of body fat are risk factors of NAFLD in children.

The revolution involving the current pattern of cultivating medical talents by combining clinical practice and education is a key step to train the high-level practical talents with clinical medicine. In this paper, we analyze the current graduate training management and quality evaluation in clinical medicine. As a result,we find some deficient exist in the present pattern of education management that is recognized as valuing scientific re-search and ignoring the clinical practice,such as a lack of effective feedback and backward in the present assess-ment system.That will inevitably influence the clinical training quality of graduate students with professional degree and lead to an awkward result that the graduate have poor knowledge in both the clinical practice and scientific re-search,resulting in a serious shortage of clinical practical talents.To solve the dilemma,our hospital constructed the intelligent digital information management platform,which has synthesized intelligent schedule,clinical rota-tion management and assessment system.With the perfect platform,the problems including clinical rotation,exam-ination,assessment in cultivating management and monitoring were primely solved. It is realizable to upgrade the graduate management from the traditional extensive management to the refined management mode and to further strengthen management,restraint and feedback system with the intelligent platform. Gradually,the fundamental purpose to cultivate the high-level talents for clinical practice could be achieved.
