Benefits in survival and quality of life have been demonstrated in patients with advanced gastric cancer receiving chemotherapy plus optimal supportive care versus optimal supportive care alone.The taxanes, which are among the most promising cytotoxic agents in clinical use have considerable activity in a number of tumor types.Paclitaxel,especially low-dose weekly administration,has shown encouraging activity in the treatment of advanced gastric cancer as a single agent.Patients treated with the low-dose weekly paclitaxel regimen had a statistically superior response rate and time to disease progression as well as clinically significant prolongation of survival.And it offers a new option for those advanced gastric patients such as the aged,poor performance status(PS) or unsuitable for combination chemotherapy,and those even with no indications for rountine chemotherapy.This review is focused on the clinical reports of low-dose weekly administration of paclitaxel for patients with advanced gastric cancer.

Objective To study the value of 5% glucose irrigation for dissection surface hemostasis in laparoscopic conservative treatment of tubal pregnancy. Methods Clinical parameters including numbers of failure in oviduct sparing, the postoperative intraperitoneal bleeding, persistent pregnancy, recurrent tubal pregnancy on the same side and normal uterine pregnancy were compared between the Experimental Group (glucose irrigation for dissection surface hemostasis; 43 cases) and the Control Group (unipolar electrocogulation hemostasis; 43 cases). Results We failed to reserve the oviduct in 10 patients in the Control Group (10/43, 23%) and in no patients in the Experimental Group (0/43) ( ? 2 =11 316, P =0 001). Recurrent tubal pregnancy on the same side was observed in 2 cases in the Control Group (2/34, 6%) and in no cases in the Experimental Group (0/34), without significant differences ( P =0 175). No postoperative intraperitoneal bleeding or persistent pregnancy was seen in both of the groups. Normal uterine pregnancy rates were 44 1% (15/34) in the Experimental Group and 40.0% (10/25) in the Control Group, without significant differences between the two groups ( ? 2 =0 100, P =0 752). Conclusions Use of 5% glucose irrigation is superior to electrocogulation for dissection surface hemostasis in the treatment of tubal pregnancy.

Methods Bacterial identification and antimicrobial susceptibility testing were?performed?with?MicroScan?WalkAway?96?PLUS?bacterial?identification?system.?All?the?data?were?analyzed?by?WHONET5.6?software. Results A total of 1499 clinical isolates were collected during 2015, of which gram positive organisms and gram negative organisms accounted for 24.7% and 75.3%, respectively. Prevalence of MRSA among S. aureus was 37.0% and MRCNS among CNS 86.3%. All (100%) Staphylococcus and E. faecalis isolates were susceptible to vancomycin, daptomycin and linezolid. About 2.8% of the E. faecium isolates were resistant to vancomycin. All the Streptococcus pneumoniae isolates were penicillin-susceptible, mainly isolated from children. The prevalence of extended-spectrum beta-lactamases (ESBLs) positive strains was 52.9% in E. coli, 30.8% in Klebsiella spp. (K. pneumoniae and K. oxytoca) and 25.0% in P. mirabilis. The ESBLs-positive strains showed higher resistance rate than ESBLs-negative strains to most antibiotics. The percentage of the P. aeruginosa isolates resistant to meropenem and imipenem was all 29.4%. The percentage of the Acinetobacter spp. (A. baumannii accounted for 85.5%) strains resistant to imipenem and meropenem was 63.0% and 64.5%, respectively. Conclusions Antibiotic resistance is still serious in Chuzhou First Hospital in 2015, especially the emerging carbapenem-resistant Enterobacteriaceae, which is of great concern.

Objective To investigate the effect of traumatic brain injury on the expressions of glial cell line-derived neurotrophic factor (GDNF) and its receptors in brain stem of rats.Methods 55 male Sprague-Dawley rats were divided into the normal control group, sham surgery group and injury groups. The rats of injury groups were subjected to Marmarou's closed traumatic brain injury and then were subdivided into 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 48 h, 72 h and 5 d groups according to the time elapsed after injury. The expressions of GDNF and its receptors (GFRα-1 and Ret) were tested with immunohistochemistry.Results Mild expressions of GDNF and its receptors were observed in brain stem of rats in the normal control group and sham surgery group. The number of GDNF positive neurons reached the peak level at 2 h in brain stem after injury, and that of GFRα-1 and Ret positive neurons reached the peak level at 4 h after injury.Conclusion The expressions of GDNF and its receptors increase significantly at the early time in brain stem of rats after injury. The similar temporal patterns of expressions of GDNF and its receptors are observed in brain stem after brain injury.
