OBJECTIVE To study drug resistance status of infected bacteria in abdominal surgical wound for their countermeasures. METHODS The abdominal surgical infection of a hospital was investigated from Jan 2000 to Dec 2004.Bacterial isolation and identification were carried out complying with National Operation Procedure of The Clinical Laboratory.Drug sensitivity test was performed with KB method. RESULTS The infection rate was 4.1%.The species were predominated by Gram-negative bacilli(71.1%),especially Escherichia coli(17.2%),Pseudomonas aeruginosa(16.7%) and Klebsiella pneumoniae(12.7%),and they all beared high antibiotics resistance. CONCLUSIONS Special attention should be paid to abdominal surgical wound infection.

Objective To evaluate the influence of duration of laser irradiation on histomorphometric meas- urements in experimentally tenotomized and repaired rabbit Achilles tendons and to explore the best irradiation time. Methods A total of 20 male New Zealand rabbits aged 10-12 weeks were used and randomly divided into 4 groups:a control group and three experimental groups.All the animals underwent surgical excised and then repair of their Achillis tendon.The animals in the control group were then treated with sham laser irradiation,while those in the three experimental groups were treated with 10,20 and 30 minutes of He-Ne laser irradiation(632.8 nm, 18.9 mW)daily,respectively,for 14 days.On the 28th day after surgical operation,the animals were sacrificed and their Achilles tendons were sampled.HE stain and Van Geison stain were used to observe morphometric changes of tendons.The SDS-PAGE electrophoresis method and CS-930 photodensity scan instrument were employed to measure the content of typesⅠandⅢcollagen.Results it was shown that laser irradiation enhanced cell proliferation,cel- lular content,granulation tissue formation and collagen deposition in laser-treated tendons,especially in those irradia- ted for 20 minute daily,as compared to the control group.TypeⅠand typeⅢcollagen levels were significantly in- creased at the 28th day in the healing tendons and the ratio of collagenⅢtoⅠincreased in all the 3 experimental groups,and the increase of both collagen content and ratio of collagen typeⅢtoⅠwas significantly greater in those ir- radiated 20 minutes daily(P

Objective To translate questionnaire for urinary incontinence diagnosis (QUID) into Chinese and to test its reliability and validity. Methods The English version of QUID was translated into Chinese. The clinaical data of 95 patinents with urinary incontinence who were test by urinary dynamic study in Peking Union Medical College Hospital from May 2014 to May 2015 were analyzed prospectively. The reliability of QUID was evaluated by completing QUID twice. The validity of QUID was evaluated by the standard of urinary dynamic study. Results Internal consistency (Cronbach α) of the items that pertained to stress urinary incontinence (SUI) and to urge urinary incontinence (UUI) were 0.91 and 0.89, respectively. Test-retest reliability (Kappa) was 0.795 and criterion validity (Kappa) was 0.62. Sensitivity and specificity were 83%(43/52) and 86%(37/43), respectively, for SUI, and 72%(13/18) and 86%(66/77), respectively, for UUI. Conclusions QUID has good reliability and validity. It could be used in Chinese urinary incontinence women.

Objective To investigate the characteristics and influencing factors leading to sudden cardiac death (SCD) of incarcerated prisoners. Methods Seventy-five SCD cases of prisoners between 2000 and 2013 in Henan province were collected, and environment, psychological and physical factors were retro-spectively analyzed. Combined with histopathological results, specific factors of SCD were also studied. Results In the 75 cases, 21 cases (28%) had definite chronic past medical histories, and 75 cases (100%) had cardiovascular disease confirmed by autopsy. Conclusion Due to presence of the potential cardiac diseases, special incarcerated environment, psychological stress, and body-restraint might be the precipitat-ing factors in SCD of those prisoners.

Objective To investigate the effect of quality control circle on reducing incidence of fecal incontinence dermatitis of intensive care unit (ICU) patients. Methods Quality control circle team was set up and theme was determined then retrospective analysis was carried out for the occurrence of defect in patients with fecal incontinence dermatitis from January to May 2014 before quality control circle activities. Occurrence reasons were explored and corrective measures were formulated and implemented.After the implementation of quality control circle,the occurrence of defect from June to October 2014 was observed. Results After the implementation of quality control circle,the occurrence of fecal incontinence dermatitis reduced from 24.5%(24/98) to 10.4% (10/96) and the difference was statistically significant,χ2=6.65, P<0.05. Conclusion Quality control circle is effective for reducing the occurrence of ICU fecal incontinence dermatitis and continual improvement of nursing quality.

OBJECTIVE To discuss the infection rate of Chlamydia trachomatis(Ct) and Ureaplasma urealyticum(Uu) in patients with non-gonococcal infection.METHODS Fluorescence quantitative PCR method was used on 1025 cases and 30 cases of NGU patients for Ct and Uu detection.RESULTS Of 1025 NGU patients,positive Ct alone accounted for 156 cases,the positive rate was 15.22%.505 cases were separate Uu,the positive rate was 49.27%.Ct,Uu mixed in 217 cases,the positive rate was 21.17%.The detection rate was 85.66%.Uu infection rate in women was more than that in men(?2 = 104.56 P0.05).of control group,the Ct Uu Results negative.CONCLUSIONS In NGH patients,Uu is most common pathgen in man and woman.To diagnosis of NGU,Uu and Ct should be followed by Ct infection rate but no gender tested at the same time to avoid missed diagnosis.

Objective To observe the imaging features of partiallythreaded screw fixation using in various kinds of C2 pedicel fracture.Methods CT image materials of 160 Chinese Han patients who suffered from atlantoaxial injury without vertebral body and pedicle fracture of C2 was included in this study,including 120 males and 40 females.Pedical trajectory selected according to Ebraheim method in threedimensional CT reconstruction was analyzed in ADW 4.4 workstation.The posterior wall fracture of C2 vertebral body,isthmus fracture and fractures under C2 laminar were simulated according to clinical observation.The trajectory length (partiallythreaded screw length) from entry point to anterior cortical bone of C2,bolt shank length from entry point to fracture line and fillet of screw length from fracture line to anterior cortical bone of C2 were measured.Relations between height,gender and partiallythreaded screw length bolt shank and fillet of screw length was evaluated.Results Male height was 167±7.9 cm on average,and female was 156±6.6 cm.The length of partiallythreaded screw was 29 mm in male and 25 mm in female on average.Height and gender was positively correlated with partiallythreaded screw length.In posterior wall fracture of C2 vertebral body,length of bolt shank was an average of 17 mm in male and 15mm in female,while fillet of screw length was 12 mm in male and 10 mm in female.The mean length of bolt shank was 14mm in male and 13 mm in female,while mean fillet of screw length was 15 mm in male and 12 mm in female in isthmus fracture.In fractures under C2 laminar,length of bolt shank was 10 mm in male and 9 mm in female on average,while mean fillet of screw length was 18 mm in male and 15mm in female.Conclusion The length of partiallythreaded screw used in posterior axial pedicle fracture may have a close correlation to length and height.The length of bolt shank and fillet of screw was different according to the position of the fracture.

Objective To compare the osteogenesis effect of platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) and investigate the methods of repairing bone defect with PRF.Methods Four defects measuring 7 mm in diameter were made in the parietal bone of 16 New Zealand white rabbits.The defects named A,B,C,and D and were filled with PRF,PRF-mixed Bio-Oss (BO),PRP-mixed BO,and PRP separately.Every four rabbits were sacrificed at postoperative 2,4,8,and 12 weeks and defects were examined grossly,radiographically,and histologically.Besides,bone mineral density and bone trabecular area were determined and expressed as gray-scale values.Results Newly regenerated bone appeared at all defect areas at postoperative 2 weeks.Thereafter,more bone formations were observed over time and area B demonstrated the best bone healing followed by area C,A,and D in succession.Bone trabecular area in areas A,B,C,and D was 10.95 ± 0.58,15.45 ± 0.79,10.22 ± 0.43,and 6.58 ± 0.64 at postoperative 2 weeks with significant differences in pair comparison (F =22.869,P ＜0.01),followed by some increase at postoperative 4 and 8 weeks.Whereas,bone trabecular area in areas A,B,C,and D increased largely at postoperative 12 weeks (35.09 ± 0.58,59.44 ± 0.60,50.75 ± 1.56,and 30.94 ± 1.19) and showed significant difference when compared in a pair (F =1 002.904,P ＜ O.01).Conclusion PRF is superior to PRP in promoting bone formation,but a much better effect of PRF/BO composite is observed in bone repair.

Objective To evaluate the clinical efficacy and adverse reactions of alizarin combined with anti-tuberculosis therapy for multidrug resistant pulmonary tuberculosis (MDR-PTB).Methods A total of 200 confirmed MDR-PTB patients admitted in the Affiliated Hospital of Hangzhou Normal University during June 2013 and June 2015 were enrolled in the study.Patients were randomly divided into study group and control group (100 in each).Both groups were given standard anti -tuberculosis treatment for 8 months, and additional alizarin was given to study group .Chi-square test was used to assess the differences in clinical efficacy, sputum negative conversion rate, cavity closure and lesion absorption rate , as well as the incidence of adverse reactions between two groups ( including patients categorized according to TCM syndrome ). Results There were 39 markedly effective cases, 51 improved cases, 10 ineffective cases in study group, and 22 markedly effective cases, 35 improved cases, 43 ineffective cases in the control group.The total effective rate in study group was significantly higher than that in control group (90% vs.57%, χ2 =28.262, P <0.01).For patients with TCM syndrome differentiation as phlegm -heat stagnating lung and those with qi-stagnation induced blood-stasis, alizarin combination therapy had significantly higher total effective rate than standard anti -tuberculosis treatment (78.78% vs.63.33%, χ2 =7.187, P <0.05;95.74% vs.42.31%, χ2 =73.997, P <0.01), but the difference was not observed in patients with TCM syndrome differentiation as deficiency of qi and blood (95.00% vs.88.89%, χ2 =5.025, P >0.05). There was no significant difference in sputum negative conversion rate between two groups (76% vs.55%,χ2 =2.190, P >0.05).The cavity closure and lesion absorption rate in study group ( 91%) was significantly higher than that in the control group (54%,χ2 =38.294, P <0.01).The adverse reaction rate in study group was 27%, which was significantly lower than that in control group (66%, χ2 =30.570, P <0.01).Conclusion Alizarin in combination with standard anti -tuberculosis therapy can improve the clinical efficacy and reduce adverse reactions in treatment of MDR -PTB.
