Background Vancomycin has been increasingly recommended for the management of endophthalmitis,but few research report has been published about the pharmacokinetics of intravitreal vancomycin up to now.It is necessary to have an exact method to measure the concentration of vancomyein in animal eyes after intravitreal injection.Objective This study was to observe and compare the phamacokinetical process of vancomycin in serum,vitreous and aqueous humor between normal and infected rabbit eyes.Methods Seventy-two healthy adult rabbits were randomly divided into normal group and infected group and 36 rabbits for each.The animal models of endophthalmitis were established by intravitreal inoculation of 2000 CFU/ml staphylococcus aureus in the right eyes of rabbits in the infected group.Once endophthalmitis developed,0.1 ml vancomycin ( 10 g/L) solution was injected into the vitreous of every rabbit.The peripheral blood,vitreous and aqueous humor samples were respectively collected in 4 rabbits for each group at 0.5,2,4,6,12,24,48,72 and 84 hours after injection for detection of vancomycin concentration by high performance liquid chromatography(HPLC-UV).3p97 software was used to create fit parameters of pharmacokinetics.This experiment followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission (Version 1988).Results The accuracy of HPLC fitted the detecting request of biological specimen.The concentration-time data of vancomycin in normal rabbit aqueous humor and vitreous was subject to two-compartment model.The pharmacokinetic parameters were separately as following:Cmax was 50.16 mg/L and 751.42 mg/L,t1/2was 51.04 hours and 53.21 hours.The concentration-time data of vancomycin in infected rabbit aqueous humor and vitreous was subject to one-compartment model.The pharmacokinetic parameters were separately as following:Cmaxwas 24.94 mg/L and 687.66 mg/L,t1/2was 11.42 hours and 12.91 hours.The concentration of vancomycin in serum was much lower and almost undectable.The concentration of vancomycin in vitreous was gradually reduced as the prolong of time after injection in both normal group and infected group,but a obvious decline after increased level was scen in aqueous humor.Compared with normal group,the concentrations of vancomycin in both vitreous and aqueous humor were reduced at various time points(P<0.05,P<0.01 ).Conclusions HPLC is simple,highly sensitive and specific for the pharmacokinetic analysis of vancomycon.These results indicate that pharmacokinetic parameters of vancomycin alter in pathological condition,which is helpful for us to establish the better treatment guidelines for endophthalmitis.

Objective To explore the effectiveness and safety of totally laparoscopic distal gastrectomy (TLDG)and laparoscopically assisted distal gastrectomy (LADG)for gastric cancer.Methods The comparative studies of TLDG and LADG published between 2008 and 2014 were searched from PubMed,EMBASE,Chinese Biomedical Literature Database (CBM),China National Knowledge Infrastructure (CNKI). After screening for inclusion, data extraction,and quality assessment,RevMan 5.3 software was used for Meta-analysis.Results Ten studies of 2 212 patients were included in the Meta-analysis,among whom 930 cases underwent TLDG and 1 282 cases underwent LADG.The results of Meta-analysis indicated that compared with LADG,TLDG had the advantages of less blood loss (WMD= - 20.70,95%CI:- 30.81 - - 10.59,P <0.01),less usage of analgesic (WMD=-0.38,95%CI:-0.74 - -0.02,P =0.04),more retrieved lymph nodes (WMD= 2.98,95%CI:0.71 -5.26,P =0.01).However,the Meta-analysis showed no statistically significant differences in the operation time, postoperative time-to-first flatus and oral intake,postoperative hospital stay,length of proximal resection margin, C reaction protein (CRP)level at postoperative day 1,incidence of overall complications and anastomosis-related complications.Conclusion TLDG is safe and effective with less blood loss, less pain than those of LADG. Moreover,it has comparable results to conventional LADG,with no increase of postoperative complications.

Objective To observe the clinical efficacy of intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei) in preventing constipation after craniocerebral injury. Method Two hundred patients with acute craniocerebral injury were randomized into a treatment group and a control group, 100 cases each. The control group received conventional nursing care to prevent constipation, while the treatment group was additionally treated with intradermal needle plus acupoint application with Da Huang (Radix et Rhizoma Rhei). The occurrence of constipation within a week was observed in the two groups. Result The occurrence rate of constipation was 12.0% in the treatment group versus 32.0% in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Intradermal needle plus acupoint application can effectively reduce the frequency of constipation in patients with acute craniocerebral injury.

AIM: To observe the inhibition of c-Met inhibitor on proliferation of lens epithelial cells (LECs).METHODS: Human's LECs were cultured and hepatocyte growth factor (HGF) and K252a were added to second passage of cells supplied with Dulbecco's modified eagle's medium (DMEM). MTT assay was used to examine the proliferation of LECs, and Western-blot was used to detect the expression change of Bcl-2 and Caspase-3.RESULTS: The photodensity (A) of HGF (50nmol/L) + K252a (30nmol/L) was not significantly different from that of DMEM control (P>0.05). The expression of Bcl-2 and Caspase-3 were not significantly different from that in the control group.CONCLUSION: K252a, the inhibitor of c-Met, can effectively inhibit the proliferation of LECs.

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32%.The infection rate in male[47.15%(611/1296)] was significantly higher than females [28.68%(273/952),x2 =34.55,P < 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34% (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24% (420/889)],followed by cadres and staffs[38.38%(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38%(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

ObjectiveTo observe the inhibition effect of docetaxel-loaded lipid microbubbles (DLLM) combined with ultrasound targeted microbubbles destruction (UTMD) on microvessel in rabbit VX2 liver tumor models.MethodsSixty rabbits were randomly divided into 6 groups (n= 10),i.e.Doc group (used docetaxel only),DLLM group (used docetaxel-loaded lipid microbubbles),Doc+US group (used docetaxel combined with ultrasound positioning irradiation),PLM+US group (used microbubbles combined with ultrasound positioning irradiation),DLLM+US group (used docetaxel-loaded lipid microbubbles combined with ultrasound positioning irradiation) and control group.The expression of CD34 and VEGF and microvessel density (MVD) were compared among different groups.ResultsAfter treatment,the expression of CD34 in DLLM+US group was lower,the MVD of DLLM+US group was markedly lower than that of the other groups (P<0.01),while the expression of VEGF in this group was the lowest among all 6 groups (P< 0.01).ConclusionDLLM combined with UTMD can inhibit the generation of microvessels in rabbit VX2 liver tumor,thus inhibit the growth of the tumor.
