Further researches of medical reagents play an important role on increasing therapeutic effect and reducing adverse effect, which are fitted for the emergent requirements of clinical medicine and the development of medical researches and pharmaceutical industry. Extended release preparation may offer the human body with a suitable blood-drug concentration, reduce the administration and obtain the satisfactory efficiency. The profound administration system and treated site broaden the preparation technique of extended release reagents and the development of new preparations. Generally, extended release reagents are prepared to delay the drug release based on the eligible materials, which should be selected according to the influence of physiologic factors on the performance of extended release reagents, such as drug absorption, distribution, metabolism, and time of extended release, etc. There are various kinds of extended release materials, and over 40 varieties have been applied for the current production. This paper is designed to introduce the development of medical extended release materials and the effect of extended release fluorouracil.

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.

Neuroanatomy knowledge is the key to improve the teaching quality of neurosurgery and anatomy teachers' participation in neurosurgery teaching can obviously improve teaching effect. Combined with case-based teaching, we enabled medical students to master the system knowledge from the basic to the clinical , cultivating their clinical thinking ability and the ability to solve clinical problems. Cooperation between clinical medicine teachers and basic medicine teachers can promote the update of knowledge, work out teaching plans together, and improve the quality of teaching.

This article reviews the recent representative studies in this field, and analyzes the effects of the application of statins in the treatment of acute ischemic stroke on prognosis.

Objective To study current situation of creativity among medical students and its influential factors, and to explore structural equation model about influential factors of creativity. Methods The sample was randomly chosen by using cluster-based sampling method, 413 students in medical university were tested by Williams creativity scale and the influential factors of creativity questionnaire. Results Among the medical student's creativity characters, the most extrusive character was challenge(2.35±0.26), the more important were curiosity(2.29±0.28) and risk-taking(2.21±0.27), and imagination(2.04±0.33) was less important. The structural equation model of influential factors of creativity implied that mental health was the most important factor about improving medical student creativity and by changing study style could promote creativity of medical students. Conclusion By establishing structural equation model, we not only study the influential factors of creativity in realistic view, but also master important extent of each influential factors theoretically.

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.

[Abstract ] Objective Ubiquitin carboxyl hydrolase L1(UCH-L1) is a neuron cytoplasm protein and increased UCH-L1 lev-el in cerebrospinal fluid( CSF) indicates brain injury.The study aimed to indentify UCH-L1 level in CSF of patients with subarachnoid hemorrhage(SAH) and assess the prognosis value of UCH-L1. Methods Retrospective analysis was made on 40 aneurismal SAH patients hospitalized in our department from August 2014 to February 2015.In the experiment group, CSF was taken by lumbar punc-ture in day1-day3, day5-day7, and day8-day10 after subarachnoid hemorrhage.In the control group, a single CSF sample was collect-ed during spinal anesthesia before surgery in 10 patients without neurologic disease.ELISA was applied to determine the concentration of UCH-L1 in CSF followed by comparison.Analysis was also made on relationship of the changes of UCH-L1 and modified rankins scale( MRS) 6 months later. Results CSF UCH-L1 concentrations in all SAH patients were significantly increased in day1-day3 ( P<0.05) after SAH, peaked in day5-day7 (P<0.01) and elevated un-til days 8-10 ( P<0.01 ) .MRS at 6 months showed a significant correlation with CSF levels of UCH-L1 in day5-day7 ( correlation co-efficient CC=0.691, P=0.001) and day8-day10 (CC=0.583,P=0.03), but not in days1-day3 (CC=0.364,P=0.08).SAH pa-tients with a good outcome at 6 months ( MRS<4) had much lower UCH-L1 levels in day5-day7 ( P=0.001) and day8-day10 ( P=0.041) than those with a poor outcome (MRS≥4).Higher UCH-L1 level at day5-day7 was a predictive marker of poor outcome in bi-nary logistic regression analysis (P=0.003); Conclusion The study suggests that increased CSF UCH-L1 level in day5-day7 after SAH is correlated with higher MRS and predicts an adverse clinical outcome 6 months after SAH.

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.
