Objective:To evaluate the effect of continuing intervention on prophylactic application of antibiotics in sterile operation in urology department by clinical pharmacist to provide reference for the clinical prophylactic application of antibiotics. Methods:All cases of discharged patients underwent sterile operation in urology department of our hospital from July 2010 to June 2014 were divided into three groups according to the intervention time and methods: non-intervention group(n=141), stage Ⅰ intervention group(n=139), stage Ⅱ intervention group (n=162) and stage Ⅲ intervention group (n=137). The prophylactic application of antibiotics was statistically analyzed. Results:After the continuing intervention, the prophylactic application rate of antibiotics in the three inter-vention groups was decreased significantly from 100% before the intervention respectively to 34. 5%,18. 5% and 14. 6% after the in-tervention (P<0. 01). The rationality rate of prophylactic application was improved significantly from 36. 9% before the intervention respectively to 58. 3%, 63. 3% and 85. 0% after the intervention (P<0. 01). The course of prophylactic application was decreased significantly from (138.2 ±31.6)h respectively to (89.9 ±48.0)h,(72.8 ±32.5)h and(45.1 ±29.5)h (P<0.01) and the post-operative infection rate was decreased from 2. 8% respectively to 2. 1%,1. 8% and 1. 4%. Conclusion:The pharmaceutical interven-tion is feasible and valid to improve the rational prophylactic use of antibiotics in urological surgery.

Whole blood viscosity 1, whole blood viscosity 2 and whole blood viscosity 3 decreased and IgG, IgA and IgM increased after treatment compared with before in the patients, but there were no statistically significant differences (P>0.05). Conclusion Movable cupping has clinically a certain improving effect on bodily sub-health status.

OBJECTIVETo investigate the semen quality and its influencing factors in preconception males in Nanjing area so as to provide some evidence for working out effective intervention measures.

METHODSTotally 687 men receiving preconceptional physical examination were enrolled in this study. A questionnaire survey was conducted among the subjects along with an analysis of their semen quality.

RESULTSThe median of sperm concentration was 63.3 x 10(6)/ml (95% CI [19.88-119] x 10(6)/ml). The median of grade a sperm was 33.03% (95% CI [19.38-55.05]%), that of grade a + b sperm was 52.08% (95% CI [39.53-69.37]%), and that of teratosperm was 91.75% (95% CI [69-100]%). The median concentration of seminal plasma PMN-elastase was 195.55 ng/ml (95% CI [76.16-3330.38] ng/ml) and that of seminal plasma zinc was 7.62 μmol/L (95% CI [1.5-23, 45] μmol/L). The positive rates of Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), and Gardnerella vaginalis (GV) were 42.4%, 0.3%, and 2.4%, respectively. The median of sperm DNA fragmentation index (DFI) of those whose wives had a history of adverse pregnancy was 20.25% (95% CI [2.15-68.25]%). Multivariate logistic regression analysis suggested that mental stress (OR 1.567, 95% CI [1.081-2.27]) and sedentariness (OR 1.772, 95% CI [1.211-2.592]) were independent risk factors for asthenospermia.

CONCLUSIONThe sperm quality of preconception males in Nanjing area is not encouraging, and it can be improved by changing undesirable lifestyle and reducing mental stress.

This study was designed to explone whether catalpol exerts a protective effects on kidney of diabetic rats and its possible mechanism.Insulin-like growth factor- I ( IGF- I ) and protein kinase B (PKB/Akt)mRNA and protein expression in kidney of diabetic rats were up-regulated as results of assessments by RT-PCR,immunohistochemistry and Western blot.Catalpol could partially reduce IGF- Ⅰ and Akt expressions in kidney of diabetic rats,and thus alleviate the damage of kidney.

OBJECTIVETo investigate the effect of intravenous bone marrow-derived mesenchymal stem cell (MSC) transplantation for early intervention of lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice.

METHODSThirty-six mice were randomized into control group, PBS-treated ALI group, and MSC-treated ALI group. In the latter two groups, mouse models of ALI were established by intranasal instillation of LPS, and 1 h later, the 4th passage of MSCs isolated from the bone marrow of mice or PBS were administered via the tail vein. The histological findings, lung wet/dry (W/D) weight ratio, neutrophil count and protein and cytokine contents in the bronchoalveolar lavage fluid (BALF), and myeloperoxidase (MPO) level in the lung tissue were analyzed at 24 h after MSC administration. Engraftment of MSCs in the recipient lung was determined by fluorescent PKH26 staining and flow cytometry.

RESULTSCompared with the control group, PBS-treated ALI group showed significantly higher protein levels, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and neutrophil count in the BALF and MPO content in the lung tissue, with also severe damage of lung histology. MSCs administration significantly reduced the lung W/D weight ratio, the levels of protein, TNF-α, IL-6 and neutrophil count in the BALF and MPO content in the lung tissue, and obviously lessened the lung injury 24 h after the transplantation. MSC administration also significantly increased the level of IL-10 in the BALF.

CONCLUSIONIntravenous MSC transplantation can effectively improve the lung histology, attenuate the inflammatory response, reduce pulmonary edema in the early stage of LPS-induced ALI in mice, and such effects are independent of MSC engraftment in the lungs.

Background and purpose:Through detection of MG7-Ag expression in various types of gastric mucosa biopsy tissues as well as serum,we studied their correlation and its clinical application value in the role of prediction of gastric precancerosis and its clinical significance.Methods:Using 125 samples of gastric mucosa biopsy tissues and corresponding sera(12 samples of normal gastric mucosa,21 samples of superficial gastritis,24 samples of gastric mucosal erosion and ulcer,15 samples of atrophic gastritis,22 samples of dysplasia,31 samples of gastric cancer)MG7-Ag expression in tissues was detected by SP immunohistochemical two-step staining;enzyme-linked immunosorbent assay was used to detect serum content of antigen MG7.Results:No expression of MG7 was detected in 12 samples of normal gastric mucosa and the positive expression rate of MGT-Ag was 93.55% in 31 samples of gastric cancer.In the order of superficial gastritis,gastric mucosal erosion,ulcer,atrophic gastritis,dysplasia and gastric cancer,expression rate of MG7 was increased sequentially(P

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

OBJECTIVETo investigate the dynamic changes of neurofilaments (NFs) proteins in spinal cords of hens with phenylmethylsulfonyl fluoride (PMSF) pretreatment for exploring the mechanism of tri-o-cresyl phosphate (TOCP)-induced delayed neuropathy (OPIDN).

METHODAdult Roman hens were randomly divided into three groups, control, TOCP and PMSF + TOCP. Birds in PMSF + TOCP set were pretreated with PMSF, 24 hours later, hens in both TOCP group and PMSF + TOCP group were administrated with TOCP at a single dosage of 750 mg/kg. Then all animals were sacrificed on the corresponding time-points of 1, 5, 10, and 21 days respectively after dosing of 750 mg/kg TOCP. The spinal cords were dissected, homogenized, and centrifuged at 100,000 x g. The levels of high molecular neurofilament (NF-H), medium molecular neurofilament (NF-M) and low molecular neurofilament (NF-L) in both pellet and supernatant fractions of spinal cords were determined by SDS-PAGE and Western-blotting.

RESULTSThe hens in TOCP group showed paralysis gait at the end of 21-day experimental period. The levels of NFs proteins in spinal cords changed obviously. Compared with control, the NFs in pellet showed a dramatic decrease on day 10 and then followed by a recovery. In the supernatant, the NFs proteins showed similar changes, which decreased significantly on day 10 and almost recovered control on day 21. Such as, NF-L, NF-M and NF-H decreased by 51%, 86% and 38% on day 10. The OPIDN signs were not observed in PMSF + TOCP group, and imbalances of NFs were obviously alleviated. Compared with control, only NF-M in pellet increased by 21% (P < 0.05) on day 21, others remained no changes; The levels of NF-H and NF-M in supernatant respectively increased by 19% and 35% on day 21, others were no significant statistical differences.

CONCLUSIONTOCP may induce imbalance of NFs levels in progress of OPIDN, and PMSF pretreatment may protect animals from OPIDN by reducing above changes, which may explain that TOCP-induced imbalance of NFs may be connected with the occurrence and development of OPIDN.

OBJECTIVETo demonstrate the changes of resting energy expenditure (REE), substrate metabolism and body composition in cancer patients.

METHODSFrom September 2004 to March 2008, REE, carbohydrate oxidation (CO) and fat oxidation (FO) in 936 cancer patients and 840 control subjects were measured by indirect calorimetry. Bioelectrical impedance appliance was applied to assess intracellular fluid, extracellular fluid, fat mass (FM) and fat free mass (FFM) in the two groups.

RESULTSNo difference in REE was found between the cancer patients and non-cancer patients [(1452.2 +/- 196.4) kcal/d vs. (1429.5 +/- 182.6) kcal/d, P = 0.136]. But REE/FFM and REE/pREE were elevated in cancer patients than in controls (all P < 0.05). Of the cancer patients, 48.6% were hypermetabolic, 42.9% normal and 8.5% hypometabolic, while those were 22.5%, 58.5% and 19.0% in controls. Cancer patients had higher FO [(77.8 +/- 11.3) g/min vs. (67.1 +/- 12.1) g/min, P = 0.000], lower CO and npRQ [(68.7 +/- 10.5) g/min vs. (88.8 +/- 12.1) g/min, P = 0.000; 0.782 +/- 0.012 vs. 0.810 +/- 0.014, P = 0.000]. Cancer patients exhibited lower FM and FFM [(14.9 +/- 4.5) kg vs. (18.4 +/- 5.2) kg, P = 0.000; (44.4 +/- 7.2) kg vs. (46.1 +/- 8.1) kg, P = 0.008].

CONCLUSIONSElevated REE is common in cancer patients. Substrate metabolism of the cancer patients features in increased FO, decreased CO and npRQ, which is correlated with the elevated REE. FM and FFM loses in proportion in cancer patients.

OBJECTIVETo investigate the expression of metabotropic glutamate receptor 4 (mGluR4) in cardiomyocytes differentiated from mouse embryonic stem cells (ES cells).

METHODSES cells were differentiated into cardiomyocytes with hanging-drop cultures. Retinoic acid (RA) and dimethyl sulfoxide (DMSO) were used as positive and negative controls, respectively. The co-expression of cardiac sarcomeric protein (α-actinin or troponin-T) and mGluR4 were verified by immunocytochemistry and flow cytometry analysis. The mRNA and protein expressions of mGluR4 were verified by RT-PCR and Western blot analysis, respectively. Meanwhile, the expression of mGluR4 in prenatal mouse heart was also examined.

RESULTSmGluR4 was expressed in both mouse ES cells and ES cell-derived cardiomyocytes. The level of mGluR4 protein expression decreased during the maturation of the cardiomyocytes. The co-expression rate of mGluR4 and Troponin T in the beating embryoid bodies (EBs) was only (3.00 ±1.00)%. On the other hand, mGluR4 gene and protein expressions showed remarkable down-regulation in the development of mouse fetal heart, which was not detected in mouse adult heart.

CONCLUSIONThe expression of mGluR4 is down-regulated in the cardiomyocyte differentiation of ES cells. The trend of expression is consistent with that in the prenatal mouse heart development.
