OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:In retrospective study, the distribution,composition and drug resistance of pathogens in our hospital during Jan.-Dec. in 2015 were analyzed statistically. RESULTS:In 2015,a total of 9401 specimens were collected in microbiology laboratory of our hospital;pathogens were detect-ed in 1743 specimens with positive rate of 18.54%;1591 strains of pathogens were isolated,mainly from sputum (59.77%), urine (14.775) and blood sample (8.93%). Totally 347 strains of Gram-positive bacteria(21.81%),991 strains of Gram-negative bacteria (62.29%),253 strains of fungus (15.90%)were detected. Top 4 pathogens in the list of amount were Escherichia coli, Klebsiella pneumoniae,Pseudomonas aeruginosa and Staphylococcus aureus. S. aureus,Streptococcus pneumoniae and Staphylo-coccus haemolyticus were sensitive to vancomycin,linezolid and sodium fusidate,with resistance rate of 0;resistance rates of them to erythromycin were more than 65%. The resistance rate of S. aureus to penicillin was more than 95%,and S. haemolyticus showed high resistance rate to common antibiotics. Drug resistances of E. coli,K. pneumoniae and P. aeruginosa to carbapenems were all lower than 15%,and they were sensitive to polymyxin with resistance rate of 0. Resistance rate of E. coli to quinolones was more than 50%. CONCLUSIONS:The main pathogens are Gram-negative bacteria in our hospital,drug resistance of them are not satisfactory. Drugs most sensitive to main pathogens include vancomycin,linezolid,carbapenems,etc. The inspection of patho-gen drug resistance characteristics should be strengthened,and antibiotics should be selected rationally and normatively according to the results of drug sensitivity test.

Objective To study the protective effect of total flavones of hawthorn leaf (TFHL) on renal ischemia/reperfusion (I/R) in rats.Methods A model of renal I/R was made by clamping double renal pedical for 60 min and reperfusion for 24 h.TFHL (30 or 60 mg/kg) was injected before clamping renal ischemia. The level of serum urea nitrogen(BUN), serum creatinine(Scr), tumor necrosis factor-?(TNF-?),interleukin-1(IL-1) in serum were detected after reperfusion for 1 and 24 h,respectively,and the level of malonaldehyde (MDA) and erythrocuprein (SOD) in renal tissues were measured after reperfusion for 24 h.Results TFHL significantly decreased the level of BUN and Scr, decreased the concentration of TNF-? and IL-1 in serum. Pretreatment with TFHL also enhanced the activity of SOD reduced the concentration of MDA in renal after I/R.Conclusions TFHL has significantly protective effect on renal I/R and markedly improve the renal function. The mec-hanisms are associated with decreasing the lipid peroxidation reaction and reducing the level of TNF-? and IL-1.

The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal (CSM). Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD-1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group (substrate) was used as a control. Levels of initial and final free gossypol (FG), crude protein (CP), amino acids (AA) and in vitro digestibility were assayed. The experiment was done in triplicate. The experimental results indicated that microbial fermentation could greatly decrease (P<0.05) FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM (dry matter), respectively, and their detoxification rate were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, A. niger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA (total amino acids) contents were increased by 7.06% and 11.46%, and the EAA (essential amino acids) were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly (P<0.05). The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly (P<0.05).

Objective To investigate voicing changes of adult patients with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after H-uvulopalatopharyngoplasty (H-UPPP). Methods 56 adult OSAHS pa-tients and 40 healthy people were included in the study. Acoustic parameters and formant frequencies were measured for each patient before and after H- UPPP, and also for the control group. Results Acoustic parameters: each group demonstrated no differences in all the parameters except for normalized noised energy (NNE). NNE increased after H-UPPP. Formant frequency: F1, B1, F2, B2, F3 of OSAHS patients were significantly lower than normal control. There was no significant difference in the formant frequency before operation and one week after; however, F1 and F2 were lower than the normal control one week after surgery. One month after surgery, F1 and F2 were ob-viously higher than that obtained in one week. All the other parameters compared with normal controls showed no significant discrepancies. Conclusion Acoustic characteristics of adult OSAHS patients were different from healthy person. After H-UPPP, the vocal tracts of patients changed, thus causing improvement to the acoustic parameters and voicing qualities, especially at the formant frequency. After the surgery, the formant frequencies of the patients increased gradually to the range of healthy people.

OBJECTIVETo analyze the clinical effect and related risk factors of Gartland type II-III supracondylar fractures of humerus in children in the emergency closed reduction and percutaneous Kirschner wire fixation.
METHODSFrom January 2008 to June 2013,112 children of Gartland type II to III supracondylar humeral fractures were treated in children in emergency closed reduction and percutaneous K-wire fixation, including 72 males and 40 females with an average age of 6.2 years old ranging from 2 to 11 years old. Among them,74 cases were in Gartland type II fractures,38 cases were in type III; The duration from injury to surgery time was 2.5 to 8 hours (averaged 4.6 hours). Elbow cast was applied after operation with the elbow extended of 100 degrees for 4 to 6 weeks, then the gypsum and Kirschner wires were removed.
RESULTSAll patients were follow-up from 6 to 60 months (averaged 12 months). All fractures reached clinical healing. The final follow-up was assessed by Flynn criteria, the result was excellent in 86 cases, good in 23 cases, general in 3 cases, excellent and good rate was 97.3%. Three patients had mild cubitus varus deformity without orthopedic treatment. No pin tract infections, iatrogenic ulnar nerve injury, compartment syndrome, and complications such as Volkmann ischemic contracture occurred.
CONCLUSIONClosed reduction and percutaneous Kirschner wire fixation had advantages of exact reduction, firm fixation, fewer complications ,less pain in children undergoing emergency surgery, and.high success rate, so it is a safe and efficient treatment for humeral supracondylar fracture in children.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).
METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.
RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).
CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.
