OBJECTIVETo investigate the treatment for tibial exposure wounds.

METHODS39 patients with tibial exposure wounds were divided into three groups according to the exposure location (upper, medium and below). The local muscular flaps were designed to cover the tibial exposure, followed by skin grafts and VSD. VSD was removed one week later.

RESULTSAll the muscular flap and skin graft survived. Mild epidermis erosion happened in 2 cases, which healed spontaneously after dressing. The patients were followed up for 3-6 months with good healing and no walking malfunction.

CONCLUSIONSThe local muscular flap combined with skin graft and VSD is a simple and effective method for tibial exposure wound with short healing time and high successful rate.

Objective 　To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods　253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results　Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions　Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.

Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Objective:We aimed to explore the clinical features, computed tomography (CT) findings, treatment, and prognosis of bronchopulmonary carcinoid. Methods:Clinical data of 31 patients with primary carcinoid tumor of the lung were retrospectively re-viewed. The prognostic factors were analyzed via Cox univariate and multivariate analyses. Results: Clinical symptoms included coughing or expectoration in 17 of the 31 cases, hemoptysis or blood-stained sputum in 7 cases, and chest pains or shortness of breath in 8 cases. Six cases were asymptomatic. The CT scans showed round or oval nodules with clear boundaries, and enhancement CT scans indicated mild, homogeneous enhancement. Immunohistochemistry results revealed the positive expression rates of synaptophy-sin (Syn), chromogranin A (CgA), and neuron-specific enolase (NSE) were 90.3%(28/31), 87.1%(27/31), and 90.3%(28/31), respec-tively. Therapy and prognosis results were as follows:28 of the total number of patients underwent surgery, among which 3 underwent postoperative adjuvant therapy, 2 received chemotherapy; and only 1 refused treatment. The 1-year overall survival rates were 100%(18/18) and 92.3%(12/13), whereas the 3-year survival rates were 94.4%(17/18) and 69.2%(9/13) in the typical and atypical carcinoid cases, respectively. Cox univariate analysis results revealed that lymphatic metastasis (P=0.02), tissue types (P=0.017), TNM stage (P=0.005), and therapies (P=0.01) were the prognostic factors. Cox multivariate analysis results showed that lymphatic metastasis (P=0.032) and tissue types (P=0.002) were the independent prognostic factors. Conclusion:Compared with other lung cancers, the bron-chopulmonary lung carcinoid has no special clinical manifestation in clinical and radiographic images. The diagnosis was mainly based on histopathology results. Surgery was the main and effective treatment, whereas chemotherapy and radiotherapy showed unsatisfactory results. The overall prognosis was satisfactory. However, the atypical carcinoid was inferior to the typical carcinoid in terms of progno-sis. Pathological typing and lymph node metastasis were significant prognostic factors.

Objective To investigate the compound donkey-hide gelatin syrup in reducing adverse reactions of qi-blood weakness patients caused by clozapine.Methods 132 patients from Psychiatric Hospital of Yunnan Province between January 2010 and June 2010 were randomly divided into a treatment group and a control group.Both groups were taken clozapine orally.On this basis,the treatment group was taken compound donkey-hide gelatin syrup and the control group was taken placebo syrup.After 8 weeks treatment for both groups,the PANSS,TESS,physical examination and experiment examination were observed to evaluate the clinical efficacy and safety.Results ① the total curative effect:the treatment group was 73.53％,the control group was 65.63％,showing statistical difference (x2=2.543,P＜0.05).② PANSS scores changes before and after the treatment:PANSS score at 2,4,6,8 weeks after the treatment of both groups were [(72.51 ±27.55),(60.54±24.03),(53.12± 15.27),(48.15± 11.88) in treatment group respectively,and (70.71 ±23.90),(58.89± 18.95),(53.06± 14.38),(48.98 ± 9.78) in the control group,respectively],both showing significant difference than the same group before the treatment [(103.99±39.12) in the treatment group,(99.78±34.35) in the control group] (P＜0.05).But there was no statistical significance between two groups (F=2.413,P＞0.05).③ adverse reactions:during the treatment liver function,blood cell analysis,dystonia,Parkinson's obstacle,akathisia,abnormal gastrointestinal reaction,heart rate,heart rate variability and blood pressure in the treatment group was significantly lower than the control group (x2=4.562,P＜0.05).Conclusion Compound donkey-hide gelatin syrup can effectively relieve adverse reactions in qi-blood weak psychosis patients after clozapine treatment and improve their drug tolerance.

Objective To investigate the clinical characteristics,distribution and drug sensitivity of pathogens causing intravenous catheter-related bloodstream infections (CRBSIs) in pediatric intensive care unit (PICU) so as to use antibiotics reasonably.Methods All patients with CRBSIs in PICU of Guangdong General Hospital from September 2009 to September 2014 were investigated and the drug resistance profiles of pathogens causing CRBSIs were also analyzed retrospectively.Results Between 2009 and 2014,there were totally 10 834 catheter days and 23 episodes of CRBSIs with an incidence of 2.1 infections per 1 000 catheter days.Catheter indwell time ＜ 7 days in 9 cases (39.1％),8 to 14 days in 10 cases (43.5％),14 to 21 days in 4 cases (17.4％).There were 13 strains (56.6％) of gram-positive bacteria,5 strains (21.7％) of gram-negative bacteria and 5 strains (21.7％) of fungi.The main pathogens causing CRBSIs were coagulase negative Staphylococci (7 strains,30.4％),Staphylococcus aureus (3 strains,13.0％),Candida albicans(3 strains,13.0％),Candida parapsilosis(2 strains,8.7％),and Enterobacter cloacae (2 strains,8.7 ％).The susceptibility to Vancomycin,Linezolid and Teicoplanin of coagulase negative Staphylococ cus such as S.epidermidis and to Imipenem,Piperacillin/Tazobactam,Cefoperazone/ Sulbactam and Amikacin of gram-positive bacteria arrived at 100.0％,respectively.The candida were 100％ susceptible to Amphotericin B,5-Flucytosine,Fluconazole and Voriconazole.Twenty-one cases (91.3％) received antibiotic treatment versus no antibiotic in 2 cases (8.7％).The average number of antibiotic kinds administered on the patients with fungal infection was 4.4,bacteria were 1.4.Ten cases (43.5％) treatment with 1 kind of antibiotic,4 cases (17.4％) with 2,4 cases (17.4％) with 3,5 cases (21.7％) with more than 3.Twenty-two cases (95.7％) cured and 1 case died (4.3％).Conclusions The major species of pathogen causing CRBSIs was coagulase negative staphylococci in PICU.It is critical for clinicians to guard against fungal infection because of prolonged catheter indwelling time and more antibiotics administered before indwelling catheter.It is effective way to prevent the CRBSIs by reasonably using antibiotics and shortening the time of catheter indwelling.Monitoring CRBSIs pathogenic bacteria distribution and drug susceptibility helps reasonable administration of antibiotics in the earlier time.
