Objective:To explore the effect of repetitive high-frequency magnetic stimulation (H-F rTMS) of the dorsolateral part of the prefrontal cortex (DLPFC) combined with smoking-related cues on nicotine addicts′ cigarette craving, the concentration of exhaled CO and sleep quality.Methods:Sixty nicotine addicts were randomly divided into groups A, B and C, each of 20. All were given H-F rTMS five times a week for two weeks, while those in groups A and B watched smoking and non-smoking pictures for ten minutes, respectively. Before and after the intervention, all of the subjects self-reported their cigarette cravings using a visual analogue scale. Exhaled CO (CO ppm) was measured and the Pittsburgh sleep quality index (PSQI) was evaluated. Results:After the intervention the average craving score, CO ppm and PSQI score had improved significantly in all three groups. The average craving score and CO ppm of group A were both significantly better than in the other two groups. Conclusions:rTMS can significantly improve cigarette craving, CO ppm and sleep quality of cigarette adicts. Viewing smoking-related pictures as an addition to rTMS can even better the effects of rTMS.

The clinic ability training is the important tache of cultivating postgraduates with the degree of clinical medicine and the clinic ability training's quality control is the important issue.This paper analyzed the existent problems in cultivation at present and expatiated the steps and countermeasure we ought to adopt in light of the actual condition of our university.

The important sign of scaling graduate culture quality is the quality of doctor degree papers.By strengthening the doctor degree management and carrying out the system of outside university experts' double blind judge,the doctor degree papers can be appraised scientifically,reasonably,impersonally and justly so as to achieve the aim of promoting the quality of doctor degree thesis.

Objective: Throughing the investigation and analysis of seven cases of acute lung injury caused by a welding operation, the hazards and production pathways of harmful gases such as phosgene and nitrogen oxides are understood, which will serve as a reference for preventing similar events in the future. Methods: Throughing the accident scene environment investigation and clinical case analysis, combined with the laboratory test results, carried on the comprehensive analysis. Results: The accident caused a total of 7 people to suffer from acute lung injury to varying degrees. Three of them were sent to the ICU ward for treatment due to acute respiratory failure. After active treatment, 7 people were discharged from the hospital with obvious relief. Conclusion Welding is also a kind of profession that causes the high incidence of acute lung injury accidents. It is necessary to strengthen the knowledge training and protection awareness education of welding workers to avoid the occurrence of acute harmful gas poisoning accidents.

Objective To explore the efficacy of debridement and primary suture for mesh-related infections after tension-free inguinal hernia repair.Methods From January 2007 to December 2013,208 cases with nesh infections following inguinal hernia repairs were treated with debridement in Department of Hernia and Abdominal Wall Surgery of Beijing Chaoyang Hospital,147 cases were treated with primary suture (suture group) and 61 cases were treated with dressing change (open group).Results The mean time of mesh infection was (8.37 ± 6.89) months.The results of bacterial culture in the two groups were similar.First grade healing rate of suture group was 80.95％ (119/147),compared to zero percent in open group.Length of stay [(20.86 ± 7.90) d vs.(31.82 ± 11.50) d,t =3.47,P =0.034] and hospital cost [(3 200 ± 5 800) yuan vs.(26 500 ± 6 600) yuan,t =4.51,P =0.02] in suture group were less than in open group.No patients developed recurrent hernia in suture group compared with one recurrence in open group.Conclusions Debridement and primary suture for mesh-related infections after tension-free inguinal hernia repair could increase the rate of first grade healing,shorten average length of hospital stay and reduce total costs.

Objective:To investigate anye effect of magnetic stimulation of the sacral nerve (SMS) on acontractile detrusor disorder.Methods:Thirty spinal cord injury patients with neurogenic bladder dysfunction were randomly divided into a stimulation group and a sham group, each of 15. In a first experiment the stimulation group was treated with SMS (over S3) with a bladder volume of 100ml on the 1st day, 200ml on the 2nd day, and 300ml on the 3rd day. Each SMS session involved a total of 1500 pulses at 15Hz in 10-second bursts with 30-second intervals. For the sham group the treatment was ostensibly identical, but the coil was rotated 90 degrees. Maximum detrusor pressure was assessed before and immediately after each SMS session. In a second experiment the bladder volumes were adjusted to 200-300ml ultrasonically before treatment. Both groups were treated twice a day, 5 days a week for 4 weeks. Maximum detrusor pressures were detected at the bladder volumes of 0ml, 100ml, 200ml and 300ml before and after the 4 weeks of treatment.Results:The stimulation group′s average pressures at 200ml and 300ml had increased significantly immediately after SMS and were then significantly higher than the sham group′s averages. After 4 weeks of treatment the stimulation group′s maximum pressures were significantly higher than before treatment at all of the bladder volumes tested, and were significantly better than those of the sham group.Conclusions:SMS can significantly improve detrusor functioning, but the effect is related to bladder volume.

Porcine deltacoronavirus (PDCoV) has been recently recognized as an emerging viral pathogen that causes diarrhea in newborn piglets. A total of 254 small intestinal or fecal samples collected from 10 provinces including Henan, Hunan, Zhejiang, Jiangxi, Anhui, Hebei, Heilongjiang, Jiangsu, Shandong and Shanghai between 2014 and 2015, were screened by quantitative RT-PCR targeting the viral M gene. Eleven PDCoV positive samples were identified with a total positive rate of 4.33%. An indirect enzyme-linked immunosorbent assay (ELISA) was developed based on the recombinant S1 protein of PDCoV. This assay was used to test 609 serum samples of pigs with diarrhea symptoms collected from 10 provinces between 2015 and 2016. The positive rate of PDCoV antibody was 44.17% (269/609). The two methods can be used to monitor the PDCoV epidemiology in the levels of PDCoV specific RNA or antibody, helping better prevent and control PDCoV.
