Objective To explore the optimum time of removal of preoperative double J stent before adjuvant radiotherapy in cervical cancer. Meth?ods A total of 90 patients with cervical cancer who underwent radical surgery between January 2014 and March 2015 were retrospectively analyzed. In addition,these recruited patients also underwent preoperative placement of double J stent and had them removed before the adjuvant radiotherapy. The patients were then divided into three groups based on the time of removal of double J stent. Group A(n=21)had the stent removed 2 to 4 weeks after the surgery;group B(n=46)had the stent removed 4 to 5 weeks after the surgery;group C(n=23)had the stent removed greater than or equal to 5 weeks after the surgery. The complications caused by stent placement and their improvement after stent removal were compared among the three groups. Finally,the optimum time of stent removal was determined. Results The overall incidence of complications caused by stent placement in group B(23.91%)was significantly lower(P<0.05)than that in group A(47.62%)and group C(56.52%). The most frequent among these complications were bladder irritation(8.70%)and fever(8.70%). The incidence of hydronephrosis exacerbation after stent removal in group A (28.57%)was significantly higher(P<0.05)than that in group B(6.52%)and group C(4.35%). All the other complications were alleviated or disappeared after the removal in all the three groups. There were no significant difference(P>0.05)among the three groups concerning glomerular filtration rate,serum urea nitrogen,and serum creatinine. Conclusion The incidence of complications caused by preoperative double J stent place?ment increased along with the duration of placement,but the exacerbation of hydronephrosis should be concerned if the stent is removed too early. Therefore,the optimal time of stent removal is 4 to 5 weeks after the surgery.

Objective To investigate antimicrobial resistance of Escherichia coli (E.coli )isolated from patients with bloodstream infection,and provide evidence for rational use of antimicrobial agents in clinical practice.Methods BacT/A-lert automated blood culture system and VITEK 2 automated identification system were used for bacterial culture and identi-fication.Antimicrobial susceptibility testing and detection of extended-spectrum β-lactamases (ESBLs)-producing strains were performed by Kirby-Bauer method.Results From 2009 to 2011 ,a total of 235 strains of E.coli were isolated from patients with bloodstream infection,90 (38.30%)of which were ESBLs positive strains.The resistant rates of ESBLs-producing strains to ampicillin,cefotaxime and ceftriaxone were all 100%,but susceptibility rate to imi-penem/cilastatin and meropenem were all 100%,to cefmetazole and amikacin were >90%.The resistant rate of non-ESBLs-producing strains to ampicillin was the highest (70.63%),susceptibility rate to imipenem/cilastatin and meropenem were both 100%,to amikacin,cefotaxime,and cefmetazole were all >95%.The resistant rate of ES-BLs-producing strains was significantly higher than that of the non-ESBLs-producing strains.Ofβ-lactamase inhibi-tor,only susceptibility rate of ESBLs-producing E.coli to cefoperazone/sulbactam was>90%,susceptibility rates to piperacillin/tazobactam and ticarcillin/clavulanate were both<80%.Conclusion Antimicrobial resistant rate of ESBLs-producing strains causing bloodstream infection is high,individualized treatment strategies should be made according to antimicrobial resistance of bacteria causing infection in patients.

Objeetive To explore the effects of renal artery calcification on the progression of diabetic nephropathy (DN),the activation and its role of bone morphogenetic protein 2(BMP2) signal pathway in renal artery of rats.Methods Sixty male SD rats were randomly divided into control group(CON group),DN group and DN with vascular calcification group (DN+VDN group).Rats of group DN and DN + VDN were fed with high sugar and fat diet and injected with streptozocin (STZ) into abdominal cavity to induce diabetes.After diabetic models were successfully made,rats of group DN+ VDN were treated by vitamin D3 plus nicotine.The rats were sacrificed at 8th,12th and 16th week respectively and the levels of renal function,blood glucose and 24 h urinary protein (24-h Upro) were measured.The pathologic changes to the renal artery were observed by yon-Kossa staining and the calcium content was detected by calcium assay kit.The pathologic changes to the kidney were observed by HE.Immunohistochemistry was applied to detect the protein expression of BMP2/Smad1/Runx2/ Osterix signal pathway in the renal artery and real-time PCR were applied to detect the mRNA expression levels of BMP2 and Runx2.Results The calcium content and the deposition of black granules in DN group were significantly higher than those in group CON and lower than DN + VDN group at each time point (P ＜ 0.05).The renal function indices in group DN and group DN+VDN were gradually increased in 8th,12th and 16th weeks,and were higher than those in group CON (P ＜ 0.05).Compared with that in DN group,although the level of BUN,Scr,Cys C and 24-h Upro in DN+VDN group rats were higher at different time point,the level of Cys C at each time point and the level of 24-h Upro in the 16th week showed significant differences (P ＜ 0.05).The pathological damages of the kidney in group DN and DN+VDN showed a continual worsening trend and the pathological changes of the kidney in group DN+VDN were more serious than those in group DN.Furthermore,the levels of BMP2/Smad1/Runx2/Osterix signal protein and BMP2,Runx2 mRNA in DN rats were higher than those in CON group,lower than DN+VDN group at each time point (P ＜ 0.05).Correlation analysis demonstrated that calcium content was positively correlated with serum BUN,Scr,Cys C,24-h Upro and the expression of BMP2,Runx2 mRNA (r=0.835,0.705,0.829,0.897,0.641,0.683,P ＜ 0.01,respectively).Conclusion Renal artery calcification may participate in and promote the progression of DN,and the BMP2 signal pathway may be an important regulating factor in DN with renal artery calcification.

Objective To determine the effect of fast passage for patients' access to the emergency department of hospital on rescuing and triaging the traumatic casualties referred from the site of accident by collision between two bullet trains occurred at Wenzhou station on 23 July 2011 in order to accumulate experience of treating large number of traumatized casualties happened in a major accident or disaster.Methods A retrospective study was carried out to collect the data including the different courses of treatment for various types of injury in casualties and the length of stay of traumatized patients with different degrees of severity in the emergency department after casualties entered into the emergency department of hospital via fast passage.Results There were 136 traumatic casualties referred to hospital within 72 hours after the bullet train accident occurred at Wenzhou station.The average length of stay of patients with uncomplicated single injury in the hospital was 27min,and the average length of stay of 108 patients with multiple injuries in the emergency department was 62 min.In last year,the annually average length of stay of casualties in emergency department was 50 min longer when there was no fast passage available for patient to enter into.Conclusions The fast passage for casualties entering into emergency department not only guarantees the traumatized patients rescued in no time after bullet train accident but also shortens the length of stay in the Emergency Department.

This study was aimed to explore differential effects of various sections of the velvet antler on promoting cell proliferation in vitro. The NRK-49F cell line from rat kidney fibroblasts was used as the cell model. The cell proliferation rates of the water extracts from the upper, middle and lower section of fresh velvet antler were measured by the MTT method. BCA method was used in the detection of protein concentration. The SDS-PAGE method was used in the analysis of difference composition of the sample protein. The results showed that soluble protein content of the upper, middle and lower section were 17.89, 16.04 and 6.89 mg·mL-1, respectively. From the top to the base, the soluble protein content of velvet antler was decreased. After 24 h treatment, when the protein concentration of the upper and middle section samples of the velvet antler were 800 μg·mL-1 and 600 μg·mL-1, the cell proliferation promoting rates reached the maximum, which were 66.76% and 64.36%, respectively. And when the lower section sample of the velvet antler was 1 000 μg·mL-1, the cell proliferation promoting rates reached the maximum, which was 58.87%. After 48 h treatment, when the upper and middle section samples of the velvet antler were 800μg·mL-1, the cell proliferation promoting rates reached the maximum, which were 219.56% and 215.86%, respectively. And when the lower section sample of the velvet antler was 1 000 μg·mL-1, the cell proliferation promoting rates reached the maximum, which was 169.20%. The velvet antler on the proliferation of cells was much better than the 10% fetal bovine serum. The figure of SDS-PAGE showed the slight difference in the protein composition of three part of the velvet antler. It was concluded that all samples had promoting effects on cell proliferation with concentration-depen-dent, and the main protein in different part of the velvet antler had minor differences.

Biohydrogen production from corncob by dark fermentation was reported for the first time. The effects of the pretreatment condition, substrate concentration and initial pH on the hydrogen production were investigated in batch cultivations. The maximum hydrogen yield of 107.9 mL/g-TVS and hydrogen production rate of 4.2 mL/g-TVS .h(-) were obtained under the condition of 1% HCl pretreating substrate for 30 min, 10 g/L substrate concentration and initial pH8.0. The content of hemicellulose in corncob decreased significantly from 42.2% to 3.0% after HC1 pretreatment. The contents of cellulose, hemicellulose and lignin in the acid pretreated corncob decreased slightly in hydrogen producing process. The results indicate that the acid pretreatment of the substrate plays a key role in the conversion of corncob into biohydrogen. Fourier transform infrared spectroscopy (FTIR) was used to study the changes in the corncob composition during the treatment of chemical-microbial process. It was shown that the amorphous domains of cellulose and hemicellulose were hydrolyzed into fermentable asccharides through HCl pretreatment and the microorganisms had a devastating effect on the crystallinitiy of the cellulose.
