OBJECTIVE:To provide reference for the timely and accurate judgment of drug fever induced by Piperacillin sodi-um and tazobactam sodium for injection and rational drug use in the clinic. METHODS:The medication,clinical manifestations, laboratory examination results and the physician treatment of 30 inpatients with drug fever induced by Piperacillin sodium and tazo-bactam sodium for injection from Sept. 2013 to Sept. 2014 were analyzed retrospectively and statistically. RESULTS:Most of the drug fever induced by Piperacillin sodium and tazobactam sodium for injection occurred in continuous 7 to 14 d medication,and the cumulative dosages were between 1.3 to 2.7 g/kg;73.3% of the 30 patients had fever during the intravenous drip,with body temperature mainly≥38.5 ℃;the elevation of eosinophil and slightly increase of serum C-reactive protein (CRP) and blood cell sedimentation rate (ESR) could be used as observation indexes of drug fever,but the leucocyte reduce could’t be suitable;the body temperature dropped to normal within 24 to 48 hours after stopped using it. CONCLUSIONS:The drug fever induced by Piperacillin sodium and tazobactam sodium for injection has no correlation with the patients’gender or age,and no special diagnos-tic criteria. But it has certain correlation with duration of medication,cumulative days and dosages and it can be used as reference of judgment with the combination of hematological examination index. Clinicians should improve the understanding and attention about drug fever to stop using suspicious drug in time.

Objective To evaluate the effect of calcitonin gene-related peptide (CGRP) on anoxiareoxygenation (A/R)-induced injury to neonatal rat cardiomyocytes incubated in high glucose medium.Methods Cardiomyocytes were obtained from 1-3-day old Sprague-Dawley rats and cultured in the culture medium containing 15％ bovine calf serum and then seeded onto 6-well plates at a density of 10 × 105/ml (3 ml/well).The cells were randomly divided into 5 groups (n =9 each):normal glucose medium control group (NG group),high glucose medium group (HG group),high glucose medium + A/R group (HG+ A/R group),high glucose medium + A/R + CGRP group (HG + A/R + CGRP group),and high glucose medium + A/R + CGRP+ CGRP8-37 group (HG + A/R + CGRP + CGRP8-37 group).The cells were incubated in normal glucose (5.5 mmol/L) medium for 72 h in NG group.In HG group,the cells were incubated in high glucose (25.0 mmol/L) medium for 72 h.In HG + A/ R group,the cells were incubated in high glucose medium for 72 h and then exposed to 3 h of anoxia followed by 2 h of reoxygenation.In group HG + A/R + CGRP,the cells were incubated in high glucose medium for 72 h,CGRP (final concentration 10-8 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.In HG + A/R + CGRP + CGRP8-37 group,the cells were incubated in high glucose medium for 72 h,CGRP (final concentration 10 8 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.In HG + A/R + CGRP + CGRP8-37 group,the cells were incubated in high glucose medium for 72 h,CGRP8-37 (final concentration 10-8 mol/L) and CGRP8-37 (CGRP receptor antagonist,final concentration 10-7 mol/L) was then added to the culture media and the cells were incubated for 1 h and then underwent A/R.Apoptosis in cardiomyocytes was detected using TUNEL and apoptosis index (AI) was calculated.The lactate dehydrogenase (LDH) activity in the culture medium was analyzed.Results AI and LDH activity were significantly higher in HG group than in NG group,and in HG + A/R group than in HG group.Compared with HG + A/R group,AI and LDH activity were significantly decreased in HG + A/R + CGRP group,while no significant changes were found in HG + A/R + CGRP + CGRP8-37 group.Compared with HG + A/R + CGRP group,AI and LDH activity were significantly increased in HG + A/R + CGRP + CGRP8-37 group.Conclusion CGRP attenuates A/R-induced injury to neonatal rat cardiomyocytes incubated in high glucose medium via combing with CGRP receptor.

Objective To investigate the effects of substance P on anoxia/reoxygenation (A/R) injury to cardiomyocytes of neonatal rats.Methods Cardiomyocytes of neonatal rats were isolated from Sprague-Dawley rats,aged 1-3 days,and were cultured in 6-well plates for 72 h.The cardiomyocytes were then assigned into 4 groups (n =3 each) using a random number table:control group (group C),A/R group,substance P group (group SP) and substance P + D-SP group (group SP + D-SP).The cells were cultured routinely for 6 h in group C and the cells were exposed to 99.9 ％ N2 in an incubator at 37 ℃ for 3 h followed by reoxygenation for 2 h in the other groups.The cells were incubated with substance P with the final concentration of 10-7 mol/L for 1 h before anoxia in group SP.The cells were incubated for 1 h with substance P with the final concentration of 10-7 mol/L and D-SP (a specific antagonist of neurokinin-1 receptor) with the final concentration of 10-6 mol/L before anoxia in group SP + D-SP.The apoptosis rate and lactate dehydrogenase (LDH) activity were detected at the end of reoxygenation using TUNEL assay and LDH assay kit,respectively.Results Compared with C group,the apoptosis rate and LDH activity were significantly increased in A/R,SP and SP+ D-SP groups.Compared with A/R group,the apoptosis rate and LDH activity were significantly decreased in SP and SP + D-SP groups.Compared with SP group,the apoptosis rate and LDH activity were significantly increased in SP + D-SP group.Conclusion Substance P can attenuate A/R injury to cardiomyocytes of neonatal rats,and activation of neurokinin 1 receptors is involved in the mechanism.

Objective To summarize the clinical experience of Gilbert tension-free hernioplasty in the elderly patient under local anesthesia. Methods Seventy-six elderly hernia patients operated by Gilbert tension-free hernioplasty under local anesthesia were analyzed in operating time, postoperative complications, hospitalization days and recurrence rate, etc. Results Patients with abdominal hernia were all cured. The average operation time was 25.7 minutes and the time staying in bed after operation was 2-5 hours. The complications of incision pain, foreign body sensation and scrotum hydroceles after operation were observed in 8, 4 and 3 patients respectively. The average hospitalization period was 2.3 days. All patients were followed-up for 1-12 months and no recurrence and infection were observed. Conclusions Gilbert tension-free hernioplasty under local anesthesia is an ideal operation to treat abdominal hernia for elderly patients with less interference to physiological function, quick recovery and less complications.

Objective To study the effect of siRNA targeting survivin and tumor necrosis factor related apoptosis-inducing ligand on the proliferation and apoptosis of hepatocellular carcinoma ( HCC) cells. Methods siRNA eukaryotic expression vector was constructed and the effects of soluble tumor necrosis factor related apoptosis-inducing ligand ( sTRAIL) on HCC cells were observed. Results The recombinant plasmid Psilence ( + )-survivin was successfully constructed. Survivin mRNA expression inhibition ratio reached 73% by RT-PCR. Observed by MTT method sTRAIL failed to inhibit the survival rate of HepG2、HepG2/Silence( - ) cells at 12 h、24 h、48 h when compared to control groups. With the survivin gene being inhibited, the survival rate of HepG2/Silence( + ) cells(0. 518?0. 017) decreased in 12 h compared to control groups (0. 741?0. 005 ) and reached the lowest level in 48 h ( P

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.
