ObjectiveTo evaluate the effect of low dose of dexamethasone on the blood glucose concentration in patients undergoing craniotomy. Methods20 consecutive patients undergoing craniotomy without a preexisting metabolic disorder were prospectively randomized into 1 of 2 groups: Dexamethasone (group D, n=10) and Normal Saline (group S, n=10), who were given dexamethasone 10 mg intravenous bolus or a saline placebo preoperatively. Arterial glucose concentrations were measured immediately before and after treatment and hourly for 5 hours intraoperatively. ResultsThe arterial glucose concentration in group D increased significantly(F=3.133,P<0.05), while those in group S keep stable. Compared with group S, arterial glucose concentration in group D increased significantly 180 min after dosing(P<0.01). ConclusionIf dexamethasone is used during craniotomy, perioperative blood glucose level should be carefully monitored and controled.

Objective To investigate the clinical treatment of brucellosis spondylitis (BS) through combination of Mongolian medicine and Western medicine.Methods From December 2010 to June 2015,51 patients which were diagnosed BS at the Department of Brucellosis Hulunbuir People's Hospital were enrolled in this study.After injecting etimicin sulfate and levofloxacin for two weeks,rifampin and doxycycline were administrated orally with Silver pearl pill,Pearl pill and Yunxiang pill (tid) for one treatment cycle which contained three courses of each treatment for 3 weeks.Before and after the treatment,the clinical features and imaging examination results were observed of 2 cases and then followed up for one year.Results Before the treatment,any spinal segment can be affected especially the lumbar spine.Two cases of cervical damage,5 cases of thoracic vertebrae,47 cases of lumbar spine,2 cases of sacral vertebrae,and 39 cases of vertebral abscess were found.After treatment,low back pain symptoms disappeared in 10 cases of the patients.Thirty-nine patients with low back pain symptoms and limited movement.Two patients with low back pain aggravated,MRI examination of the lumbar spine showed lesions increased and abscess formation.The effective rate of Mongolian herbal medicine and Western medicine treatment was 96.1％ (49/51).Conclusion The combined treatment of BS through combination of Mongolia medicine and Western medicine is effective.

Objective To analyze the epidemiological characteristics of Mycobacterium tuberculosis by enterbaeterial repetitive intergenic consensus-polymerase chain reaction(ERIC-PCR)DNA fingerprint. Methods Mycobacterium tuberculosis positive sputum samples between September 2003 to May 2006 were collected and cultured.Chromosomal DNA were extracted and ERIC-PCR DNA fingerprinting was analyzed by software,such as RAPD PHYLIP and Treeview.Results A total of 42 different fingerprints were detected.Phylogenetic analysis showed that they could be classified into three clusters,the clustering rate was 72.6%.The characteristics of ERIC-PCR fingerprint patterns were related to age,drug resistance,and type of resistance.Conclusions ERIC-PCR DNA fingerprinting technique used in this study is good for epidemiological studies with its strong discrimination,simplicity and rapidness.A high level of recent transmission is found in our city.

OBJECTIVETo evaluate the clinical efficiency of selective cyclo-oxygenase-2 (COX-2) inhibitor compared to traditional nonselective NSAIDs for the prevention of heterotopic ossification (HO) after total hip arthroplasty (THA).

METHODSBy searching Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials) and Science Citation Index et al, only randomised controlled studies of selective COX-2 inhibitors VS nonselective COX-1 and COX-2 inhibitors for the prevention of HO after THA were included. The quality assessment of included studies was evaluated according to the standard of the Cochrane Collaboration, and the data were analysised by statistic software Stata 10.0. The HO incidence of both groups in different degrees was compared.

RESULTSFour eligible randomised controlled trials of totally 808 patients were included. Meta-analysis results showed that no statistically significant difference was found in overall incidence of HO (RR = 1.08, 95% CI: 0.71-1.64,P = 0.73), incidence of moderate severe HO (Brooker II and III) (RR = 0.83, 95% CI: 0.48-1.42, P = 0.49) and any grade of Brooker classification between two groups. In all included studies, 16 patients receiving nonselective COX inhibitor (4.4%) discontinued treatment because of gastrointestinal toxicity,whereas 10 patients in the selective COX-2 inhibitor group (2.7%) discontinued for gastrointestinal side effects.

CONCLUSIONThe selective COX-2 inhibitors are as equally effective as nonselective NSAIDs for the prevention of HO after THA. Considering the side effects of nonselective NSAIDs, selective COX-2 inhibitors were recommend for the prevention of HO after THA.

Recombination plasmid pMM085 possessed both immunogens heat-labile enterotoxin(LT) and fimbriae antigen K88 of enterotoxigenic Escherichia coli (ETEC). Althouth vaccine strain MM-3 carrying pMM085 had good effect to protect piglets against diarrhea due to ETEC infections,it was not ideal live vaccine for pMM085 bringing chloramphenicol resistance gene (cat). To solve the problem,the host-plasmid balanced lethal system was introduced which including the replacement of cat gene by asd gene and transformation the new plasmid to the strain X6097 which asd gene was knocked out in its chromosome. Considering pMM085 was a big plasmid (23kb) and traditional genetic manipulations was not easy to carry on,?-Red recombination system was adopt in this work to realize the replacement of cat gene by asd gene. The results indicated that ?-Red recombination system was convenient and efficient to reconstruct big plasmid.

Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.

OBJECTIVETo explore the effect of maternal cypermethrin exposure during lactation on learning and memory ability in adult female offspring, as well as the possible mechanism.

METHODSTwelve maternal mice were randomly divided into 6.25 mg/kg cypermethrin, 25.0 mg/kg cypermethrin and control groups (four dams each group, ten pups each dam, half male half female, twenty female pups each group). Maternal mice were orally administered with different doses of cypermethrin (6.25 and 25 mg/kg/d) once daily from postnatal day1 (PND1) to PND21. Maternal mice in control group were treated with corn oil. The learning and memory ability of female offspring were observed by using water labyrinth task for continuously seven days on PND60. All the female offspring were killed and the brain and hippocampus were detached after the test. The expression level of NMDA receptor NR1 protein in hippocampus was detected by Western-blotting.

RESULTSThere were no statistically significant in the difference in weight of body and brain among three groups (P > 0.05). Through the Repeated one way ANOVA, the learning time of latency in the 25.0 mg/kg cypermethrin group [(31.3 ± 17.0) s] were significantly longer than that in the control group [(21.0 ± 14.0) s] (P < 0.05). The memory time of latency in the 25.0 mg/kg cypermethrin group [(24.6 ± 21.1) s] were significantly longer than that in the control group [(14.1 ± 16.3) s] (P < 0.05). However, the difference of the wrong number among groups was not statistically significant in the test (P > 0.05).

CONCLUSIONMaternal cypermethrin exposure during lactation disturbs learning and memory ability in adult female offspring in a degree, which maybe caused by the reduction of protein level of hippocampus NR1.

Objective To evaluate the application of non-bioartificial liver support system (ALSS) combined with liver transplantation(LT) in treating mid-or end-stage chronic severe hepati- tis.Methods ALSS plus liver transplantation were employed in treating 28 patients with mid-or end- stage chronic severe hepatitis.Clinical data from the patients before and after treatment were collect- ed.The survive rate of ALSS plus LT group were compared with that of medication group 99 cases and medication plus ALSS group 30 cases.The data were analyzed with t test and X~2 test.Results After 57 times ALSS treatment,the serum total bilirubin(TBil),prothromin time(PT),bile acid, blood urea nitrogen(BUN),creatnine(Cr) and ammonia of all the 28 patients got improved(P 0.05).The clinical symptoms and signs of the patients were ameliorated at median 3 d(1～153 d). All patients were bridged to liver transplantation successfully after median 20 d(1～153 d).The 3 and 6 months post-operation survival rate of ALSS plus LT group(71.4%,71.4%) were significantly higher than those in medication group(18.2%,11.1%) and medication plus ALSS group(36.7%, 26.6%)(P

Objective To evaluate the long-term efficacy of total laparoscopic radical gastrectomy combined with delta-shaped anastomosis in treatment of distal gastric cancer. Methods The clinical data of 128 patients with distal gastric cancer who underwent laparoscopic radical gastrectomy from January 2014 to April 2016 were retrospectively reviewed. According to the different surgical methods, patients were divided into TLDG plus DA treatment group (DA group, 72 cases) and LADG plus TA treatment group (TA group, 56 cases). The operation time, intraoperative blood loss, disconnection time, postoperative exhaust time, lymph node dissection, hospitalization time and postoperative complications were recorded. Patients were followed up monthly by call, to April 2017. Results The blood loss [(55.6 ± 12.5) vs (85.6 ± 15.8) ml] and postoperative exhaust time [(2.5 ± 1.0) vs (4.5 ± 1.5) d] were significantly lower in the DA group than that in TA group (P < 0.05). There was no significant difference between the two groups in the operation time, the removal time, the number of lymph node dissection and the hospitalization time (P > 0.05). The incidence of anastomotic stenosis (0.00％ vs 7.14％), anastomotic fistula (0.00％ vs 8.93％) and anastomotic bleeding (0.00％ vs 7.14％) in DA group was significantly lower than that in TA group (P < 0.05). All the patients were followed up for 16 to 62 months in DA group. 16 patients died of tumor recurrence or metastasis, and the cumulative survival rate was 77.78％. TA group were all effective follow-up, the follow-up time of 15 to 61 months, 14 patients died of tumor recurrence or metastasis, the cumulative survival rate of 75.00％. There was no significant difference in cumulative survival rate between DA group and TA group (P > 0.05). Conclusion In the treatment of distal gastric cancer, there is a certain advantage in the effect of laparoscopic radical gastrectomy plus delta-shaped anastomosis in the treatment of distal gastric cancer over tubular anastomosis.
