Objective To investigate the distribution and antimicrobial resistance of clinically isolated pathogens from geriatrics department of a hospital in 2013,so as to provide reference for clinical antimicrobial use.Methods Distribution and antimicrobial resistance of pathogens isolated from patients in a geriatrics department between Janu-ary and December 2013 were analyzed statistically.Results Of 1 896 pathogenic strains,1 289(67.99%)were gram-negative bacteria,439 (26.00%)were gram-positive bacteria,and 114(6.01%)were fungi;the top 4 isolated pathogens were Klebsiella pneumoniae ,Pseudomonas aeruginosa ,Acinetobacter baumannii ,and Escherichia coli .Extended-spec-trumβ-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae accounted for 53.26% and 31.10% of Escherichia coli and Klebsiella pneumoniae respectively;Of Staphylococcus aureus and Staphylococcus epidermidis strains,methicillin-resistant isolates (MRSA and MRSE)accounted for 22.47% and 80.00%,respectively,of Enterococ-cus strains,vancomycin-resistant isolates (VRE)was 3.10%,Klebsiella pneumoniae and Enterobacteriaceae were highly sensitive to imipenem,meropenem and ertapenem.Resistant rate of Acinetobacter baumannii to imipenem and meropenem was 79.48% and 80.35% respectively,Pseudomonas aeruginosa had the lowest resistant rate to amikacin (10.70%). Gram-positive bacteria were highly sensitive to vancomycin and linezolid.Conclusion The major pathogens isolated from the elderly patients are gram-negative bacteria,and antimicrobial resistance is serious,surveillance of antimicrobial resist-ance is important for rational use of antimicrobial agents and control of pathogen resistance.

Objective To investigate the effect of lysostaphin on golden staphylococcal bacteria in vitro and on acestoma tissue.Methods Effects of lysostaphin on golden staphylococcal bacteria,Candida albicans and P.aeruginosa were detected by drug sensitivity test.Quantitative analysis of bacteria was used to detect the effect of lysostaphin on golden staphylococcal bacteria in 29 cases of 10%-30% TBSA.Results Most golden staphylococcal bacteria,as well as Candida albicans could be killed by lysostaphin.Lysostaphin had little effect on P.aeruginosa.Eighty-nine percent bacteria could be killed by lysostaphin after gauze with lysostaphin had been used for over 3 d,indicating lysostaphin may control bacteria quantity and improve survival rate of skin graft on granulation tissue.Gauze with lysostaphin contained biological enzymes and it had no systemic side effects.Conclusion Gauze with lysostaphin may be available on controlling golden staphylococcal bacteria as well as Candida albicans in burnt patients.Lysostaphin is effective in controlling residual trauma infected by golden staphylococcal bacteria.

Objective　To investigate whether matrix metalloproteinase-9 (MMP-9) was synthesized in pregnant cervix during parturition and its source and distribution. Methods　Cervical species (n=10, each weighing about 0.3 g) were taken from pregnant women immediately after delivery. Other cervical species (n=7) were served as negative control from those non-pregnant women but undergoing uterotomy due to other benign diseases. Immunohistochemical method (ABC) was carried out to detect the expression of MMP-9, with a monoclonal antibody against MMP-9. Results　Positive staining of MMP-9 was found in the cytoplasm of polymorphonuclear leukocytes (PMN) that had infiltrated into cervix or located in blood vessels of cervix. Scattered light positive staining were found in some interstitial cells of the cervix. No other cells including fibrocytes and lymphocytes were positive to MMP-9. No positive staining was found in control tissues. Conclusion　There are strong expressions of MMP-9 in pregnant cervix in term labor, derived mainly from infiltrated PMN. MMP-9 may be an important regulator in the process of cervical ripening.

Objective To evaluate the advantage and clinical value of javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma. Method Randomized controlled trials (RCTs) concerning javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma were made on electronic databases of CBM, CNKI, Wangfang, VIP and PubMed from 1990 to February 28, 2015. Quality of the included RCTs was assessed by Jadad scoring , and Meta-analyses were performed by RevMan5.3 software. Results Seven RCTs involving 575 patients were included in Meta-analysis. All studies were in low quality. The results of Meta-analyses showed that Javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma, compared with control groups, could increase the recent curative effect (P < 0.000 01) and improve the quality of live (P = 0.000 8), decrease the hematologic toxicities (P = 0.03) and the incidence rate of radioaction esophagitis (P = 0.02), but not enough evidence was found to prove that it can enhance survival rate (P = 0.25). Conclusions The results of Meta-analysis indicate that javanica oil emulsion injection may have therapeutic effects on the treatment of esophageal carcinoma. Yet the effects of javanica oil emulsion injection still need to be confirmed by large multi-center randomized controlled trials.

Base on the Kawakita powder compression equation, a general theoretical model for predicting the compression characteristics of multi-components pharmaceutical powders with different mass ratios was developed. The uniaxial flat-face compression tests of powder lactose, starch and microcrystalline cellulose were carried out, separately. Therefore, the Kawakita equation parameters of the powder materials were obtained. The uniaxial flat-face compression tests of the powder mixtures of lactose, starch, microcrystalline cellulose and sodium stearyl fumarate with five mass ratios were conducted, through which, the correlation between mixture density and loading pressure and the Kawakita equation curves were obtained. Finally, the theoretical prediction values were compared with experimental results. The analysis showed that the errors in predicting mixture densities were less than 5.0% and the errors of Kawakita vertical coordinate were within 4.6%, which indicated that the theoretical model could be used to predict the direct compaction characteristics of multi-component pharmaceutical powders.

Objective The purpose of this study was to assess isokinetic strength of lower extremities and find out weak muscles in Chinese elite fencers. Methods Bilateral peak torque of flexors and extensors of hip, knee and ankle in 26 national fencers,aged 23.1±2.36 yrs,were tested isokinetically at speeds of 60 and 240 deg/sec. Results (1)Hip: compared with 60 deg/sec,peak torques of bilateral extensors significantly decreased at 240 deg/sec (P<0.05), no significant difference in flexors(P>0.05); At two velocities, flexor peak torques in leading leg of men fencers were significantly higher than trailing one(P<0.05),no significant difference was found in women(P>0.05);Flexor/extensor torque ratio was lower than normal at two velocities in all fencers. (2)Knee: strength of flexors and extensors in 60 deg/ sec and extensor in 240 deg/sec of men fencers were significantly different between leading and trailing legs (P<0.05); No difference at two velocities were found in women fencers;knee flexor/extensor ratio of both legs were 0.56,0.54 for women and 0.6,0.67 for men respectively at 60 deg/sec;knee flexor/extensor ratio were within normal range at 240 deg/sec. (3)Ankle:men's peak torque in leading ankle of flexor and extensor were significantly higher than trailing leg at 60 deg/sec(P<0.05);no difference were found at 240 deg/sec for men and women (P>0.05); ankle flexor/extensor ratio were lower than normal at two velocities in all fencers. Conclusion (1)Bilateral asymmetry in isokinetic muscle strength exists in men fencers,but not obvious in women fencers. (2)Weak muscles for fencers were hip extensor,knee flexor,especially in leading knee and ankle extensor.

Objective To observe the effect of combination of Tju103 and CTLA4-Ig on engraftment, graft versus host disease (GVHD), graft versus leukemia (GVL) and anti-infection post major histocompatibility complex (MHC) haploidentical bone marrow transplantation in mice in order to seek an effective access to transplantation with less GVHD and more potential GVL and anti-infection.Methods In the presence of the recipient's antigen (normal CB6F1, H-2 bd) as a stimulus for induction of specific immune tolerance, T cells from the MHC haploidentical donors (C57BL/6, H-2 b) were first in vitro cultured with Tju103 and CTLA4-Ig, then were transfused with the donors' bone marrow cells into the preconditioned recipients. At last, the effect of combination of Tju103 and CTLA4-Ig on hematopoietic rebuilding, GVHD, GVL and anti-infection was observed in compared with CsA, Tju103 and CTLA4-Ig as controls.Results The only irradiated group (group A): All the mice (10 mice) died of failure of hematopoiesis within 11 days post irradiation, of which most (8 mice) died within 4～7 days post transplantation. The CTX-treated leukemia group (group B): All the mice (10 mice) died of leukemia within 16～23 days post leukemia cells infusion (11～18 days post BMT). CTX treatment prolonged the survival time. The only transplanted group (group C): The mice began to die from day 16 post transplantation, and all (10 mice) died of GVHD within 3 weeks. The CsA prophylaxis group (group D): 4 mice died within 8～22 days after transplantation, of which one died of leukemia, two died of infection and one died of GVHD, and the remaining 6 survived over 30 days post transplantation. The Tju103 treated group (group E): 4 mice died within 9～26 days post transplantation, of which one died of leukemia, one died of infection and two died of GVHD, and the remaining 6 mice survived over 30 days post transplantation. The CTLA4-Ig treated group (group F): 3 mice died within 14～23 days after transplantation, of which one died of infection and two died of GVHD, and the remaining 7 survived over 30 days post transplantation. The Tju103/CTLA4-Ig treated group (group G): one died of GVHD on day 19 after transplantation, and the remaining 9 mice survived over 30 days post transplantation. Conclusions CsA, Tju103 or CTLA4-Ig alone could prolong survival time and reduce incidence and degree of GVHD severity. But CTLA4-Ig could spare much ability of GVL and anti-infection while Tju103, just like CsA, couldn't. Combination of both was the most favorable way for transplantation with the most remarkable efficiency on prolongation of survival time and reduction of GVHD.
