OBJECTIVE To study the rational use of antibiotics in a comprehensive general hospital.METHODS The clinical data of 583 cases used the five kinds of most frequently antibiotics during Nov 20-26,2006 in a comprehensive general hospital were collected and analyzed.RESULTS The total five kinds of most frequently antibiotics used in this hospital were the third generation of cephalosporins,cefoperazone/tazobactam(Kaisi),flomoxef(Fuomaning),cefoperazone/tazobactam(Kaishute),cefpiramide(Xibaiao) and cefoperazone/tazobactam(Xianbita).The daily frequency of these antibiotics was rational to the drug metabolic dynamics characteristics.Some patients received the long time therapy of antibiotic,the longest one was 22 days.The frequency of over-doses in these patients was 19.9%.CONCLUSIONS Antibiotics use is apparently rational in this hospital and the training and education for drug use should be enhanced in the future.

Objective To study the feasibility and safety of the diagnostic coronary angiography by transradial approach with modified 5 F universial catheter.Methods Retrospective analysis was performed in 268 randomly chosen patients undergoing diagnostic coronary angiography by transradial approach,either with 5 F universial catheter(universial group,n=133) or 5 F modified universial catheter(modified group,n=135).The success rate and the duration of operation and fluoroscopy,the rate of error entry into branch vessel between the 2 groups were compared.Results The success rate for angiography was 87.2%(116/133) in the universal group and 97.0%(131/135) in the improved group(P

In the investigation of patients with internal disc disruption, a discography has been the best method to decide whether intervertebral disc is normal or abnormal. Magnetic resonance imaging (MRI) of the spine is a new technique which offers an alternative method of obtaining this information. Some authors have reported MRI was more accurate than discography, but other reports have indicated discography was more useful test in symptomatic lumbar disc disease. The authors performed retrospective study to evaluate the diagnostic value of the image findings of MRI and discography in the internal disc disruption. Image findings of MRI and discography were analyzed comparing to pattern of provocative pain during discography. The concordant pain at discography was considered as a gold standard for evaluation of the diagnostic value of these modalities. The image findings of MRI and discography for 60 discs of 21 patients were graded and compared with the pain response at discography. The validity and predictive value (PV) of these modalities were calculated and the correlation between these image findings was evaluated. The sensitivities of discography and MRI were 83.3% and 90.9% respectively. The specificities of these findings were 47.1% and 46.7%. The positive PV of discography and MRI were 52.6% and 55.6%, and the negative PV were 80% and 87.5% respectively. There was no statistical significance in these discrepancies. The determinations of symptomatic disc level based on image findings are unreliable. The MRI can be considered as a screening test for internal disc disruption since it is non-invasive and sensitive diagnostic tool. The fusion level should be decided by the pain pattern at discography.

Objective To systematic review the efficacy of Bifidobacterium preparation in Helicobacter pylori ( HP ) eradication therapy. Methods We systematically reviewed clinical research about the efficacy of probiotics in Helicobacter pylori eradication in multiple data-base( PubMed, EMBASE, Medline, OVID, Web of Science); After screening and assessing the quality of the data, we used RevMan 5.3.5 software and Stata 12.0 software for data analysis, then we used GRADE pro3.6.1 software assessing the quality of results.Results Six studies were included with 1396 patients,there were 690 patients in experimental group and 706 patients in control group.Compared with control group, the eradication rates calculated by per-protocol analysis [RR=1.19,95%CI(1.12,1.26),Z=5.87 (P<0.00001)]and intention-to-treat analysis[RR=1.18,95%CI(1.07,1.31),Z=3.33(P=0.0009)]in experimental group was higher,the number of diarrhea[RR=0.43,95%CI(0.23,0.79),Z=2.73(P=0.006)]/the number of nausea[RR=0.67,95%CI(0.56,0.81),Z=4.19 (P<0.0001)]/the number of taste disorders[RR=0.61,95%CI(0.32,1.13),Z=1.57(P=0.12)]in experimental group was lower.The quality of results:the eradication rates calculated by per-protocol analysis was high quality, intention-to-treat analysis and the number of nausea and the number of diarrhea was moderate quality,the number of taste disorders was low quality.Egger’s test showed there was no evidence of substantial publication bias.Conclusion Bifidobacterium preparations during standard triple HP therapy may improve the eradication rate and reduce adverse reactions.

Anterior plate fixation of the cervical spine provides good primary stability to allow early mobilization without significant external support. Despite the obvious advantages of anterior cervical fixation, neurological injury resulting from the direct trauma of a drill bit or screw are possibile with this technique. In addition, screw loosening leading to dyphagia has been reported. The cervical spine locking plate (CSLP) system maintains the mechanical advantages of internal fixation and eliminate the neurological risks of perforating the posterior cortex. The purpose of this study is to review our experience with this device, to critically assess its ability to stabilize the cervical spine, and to assess for complications associated with this device. The authors reviewed 28 consecutive patients in whom the CSLP system was applied between April 1994 to April 1995. Average age was 44 years ranged from nineteen to seventy-two. Patients with trauma were eight and degenerative diseases were twenty. Eighteen screws were inserted in C3 bodies, twenty-four in C4, forty-one in C5, thirty-six in C6, twenty-four in C7, two in Tl and nine on grafted bone. With a mean follow-up of 15 months, 27 of 28 patients went on to fusion. Mean time to fusion was three months (range 2-5). Fusion status of one patient was considered as uncertain. Three patients had screws placed in the disc rather than in bone. One patient suffered deep wound infection, which developed to tracheoesophagial fistula. No patient showed neurological injury as a result of this device.

Five fractions,Ⅰ(R_f0.06)、Ⅱ(R_f0.21)、Ⅲ(R_f0.45)、Ⅳ(R_f0.60)、Ⅴ(R_f0.75)have been obtained after HT-toxin from race 1 of Exserohilum turcicum 99-2 isolated by TLC. In all of these fractions,only fractions Ⅱ had specific toxicity to the corn leaves with Ht1 gene. Then fractions Ⅱ-1、Ⅱ-2、Ⅱ-3 were isolated from fractions Ⅱ by HPLC purification,and the bioassay result showed only fraction Ⅱ-3 was toxigentic to corn leaves with Ht1 gene but non-toxigentic to corn leaves without Ht1 gene. Fractions Ⅱ-1、Ⅱ-2 and Ⅱ-3 were scanned by UV-Vis spectrophotometer. It was shown that the fractions Ⅱ-1 and Ⅱ-2 had analogous spectrum,and especially the fraction Ⅱ-3 had a special peak at 300nm.

ObjectiveTo assess the clinical features of noncompaction of ventricular myocardium (NVM) in children. Methods The clinical data from ifve children with NVM were analyzed, including clinical manifestations, ultrasonic cardio-gram(UCG), electrocardiogram, chest X-ray, the process of diagnosis and treatment, and follow up.Results In ifve patients (3 boys and 2 girls) aged 3 months to 12 years, four of them were hospitalized because of pneumonia with heart failure. None of the ifve patients had thromboembolism. Heart enlargement was observed in all ifve patients on chest X-ray. By 2D ultrasonography, 2 patients had cardiac apex involvement, and 3 patients showed involvement of left ventricular wall and interventricular septum. In one patient, congenital partial defect of the endocardial cushion was observed. All patients were followed up for 3 to 36 months. One patient died of heart failure, 3 patients survived, and one patient was lost to follow-up.Conclusions The common clinical manifestation of NVM is the heart failure. UCG is preferred for NVM diagnosis. In children with refractory pneumonia and heart failure, NVM should be suspected.

Objective:To explore the prevalence rate of suicidal ideation and its risk and protective factors in military personnel.Methods:A total of 2071 military personnel were investigated by stratified random cluster sampling in May to August of 2015.The Question 7 of Beck Depression Scale (BDI) was used to test suicide ideation (item 7 score ≥ 1 was dovetailed in suicide ideation group).Family,social demographic and occupational factors were assessed with the self-made general characteristics questionnaire.The data were analyzed with multiple stepwise logistic regression.Results:There were 382 (18.4％) military personnel whose scores of item 7 were ≥1.Family history of suicide (OR =42.97,95％ CI =29.14-63.35),surrounding suicide (OR =2.46,95％ CI =1.75-3.46),drinking (OR =1.64,95％ CI =1.31-2.07) and level of education (OR =1.38,95％ CI =1.01-1.90) were risk factors of suicidal ideation.Protective factors were (OR =0.60,95％ CI =0.50-0.72) and station (OR =0.15,95％ CI =0.03-0.64).Conclusion:It suggests that in suicidal prevention for military,more attention is deserved paying to those military personnel who have family history of suicide,surrounding suicide,drinking habit,and are stationed in remote areas and air force.
