0.05). Conclusion:The effect of intravenous vecuronium made in Xianju Pharmaceutical Co. for neuromuscular blockade is definite and safe.

Objective To investigate in knowledge rate of 120 first aid and satisfaction rate with emergency services among Nanchong citizens. Methods 360 patients who received prehospital first aid from three hospitals and their accompanies were selected from January to June 2010. The investigation content included knowledge rate of 120 first aid and satisfaction rate with emergency services. Results Results showed that about half of those surveyed still did not know the emergency phone"120" and its function, lacked self-help and self-protection knowledge, some respondents felt quite helpless upon daily life of electric shock, gas poisoning, coma and traumatic accidents. The attitude of the majority of emergency personnel was good or better, but still very stiff or irresponsible attitude existed in those few. This undermined the "120" and the image of credibility and emergency personnel. Conclusions There is an urgent need for universal coverage of on-site first aid knowledge and enhance awareness of first aid. Full-time staff in emergency department must pay close attention to the knowledge of first aid training, mastering the technique of bleeding control and bandaging, fixing, handling and CPR, as well as the use of instruments and equipment equipped in vehicles. Only in this way can we continuously improve the treatment of critically ill patients and increase survival rate.

Objective To explore the relationships between brain-derived neurotrophic factor gene G196A polymorphisms and psychopathology and the cognitive function in schizophrenic patients.Methods 224 patients and 220 normal controls were examined with polymerase chain reaction(PCR),denaturing polyacrylamide gel electrophoresis and silver staining to determine genotype and allele of G196A.Clinical symptoms were assessed with the Positive and Negative Symptom Scale (PANSS).Cognitive function was assessed with Wisconsin card sorting test (WCST) and Trail Making Test(CPT).To analyse the differences of the scores of Scale for the Assessment of Positive Symptoms(SAPS) and Scale for the Assessment of Negative Symptoms (SANS) among the patients with the genotype G/G,G/A and A/A.At the same time,the differences of the performance of WCST and CPT were analyzed.Results ①There were no significant differences of the genotypes G/G,G/A and A/A and allele G and A between patients and controls.②There were significant differences of the genotypes A/A between patients with Positive Symptoms and patients with Negative Symptoms (x2 =4.558,P ＜ 0.05).③There were no significant differences in the performances of complete categorizations and persistent wrong numbers of WCST and the performances of CPT among three groups of patients with genotype G/G,G/A and A/A (One-Way ANOVA,all P ＞ 0.05).Conclusion BDNF gene G196A polymorphisms are not associated with schizophrenia and the cognitive function but are associated with positive symptoms of schizophrenia.

OBJECTIVE To investigate the use of a chlorine dioxide-based dental unit waterline(DUWL) treatment to reduce the colonization and growth of heterotrophic bacteria.METHODS Twenty-two dental units with self-contained water systems were randomly selected.Three of the units and tap water served as controls.Twenty-three water samples were taken at baseline and once a week for five weeks.They were serially diluted,spread-plated in duplicate onto R2A agar plates and incubated at 37 ℃ for 7 days.RESULTS At baseline,the 3 control DUWLs had a median count of 8440 colony-forming units/milliliter(CFU/ml) and the 19 treated DUWLs had a median count of 9160 CFU/ml.By week 1,18 of the 19 treated DUWLs had counts of less than 200 CFU/ml,and by week 4,the median count for all of the treated DUWLs was 0 CFU/ml.The measurement at week 5 showed that the reduction to below 200 CFU/ml had been maintained.Scanning electron examination revealed a similar results,with biofilm accumulation more evident in the untreated control specimens.CONCLUSIONS Using a chlorine dioxide-based disinfectant in DUWLs can achieve the American Dental Association(ADA) goal of less than 200 CFU/ml of heterotrophic bacteria per milliliter of unfiltered output water.

Objective To measure the costs of primary health services in the community for developing government compensation standard and prediction of budget in 201 5.Methods Literature review and panel discussions were used to build the index database.A two-round Delphi expert consultation determined the work to do and steps for community healthcare standards.60 community health centers were sampled by stratified random sampling for survey,and the work hours,workload and service volume of respective services in 2013 were measured according to the service standards of primary care.Results The community primary care consists of the categories of outpatient services,nursing care, laboratory tests and drug management,totaling 20 services and 88 working procedures.The total work hours of primary healthcare service at 60 community health centers were 2 557 187.9 hours,which is adjusted to 2 959 21 5.1 hours based on workload coefficients.Based on the income standards of employees at the community health centers investigated,and the human cost price which was recommended by the experts,the total costs of primary healthcare of the 60 centers were 245 million,248 million and 318 million respectively,and the average cost was 71.0 yuan,71.8 yuan and 92.1 yuan per visit respectively.By such standards,the government should subsidize 38.9 ~ 60.0 yuan per visit to the centers.The total expenditure of primary healthcare of all communities in Shenzhen in 201 5 was predicted to be 314 to 407 million,for which the government is expected to subsidize 1.68~2.58 billion.Conclusion The subsidies for community primary healthcare fall short as the cost per visit runs up in 2013 to 71.0 yuan per visit or more,far above the current subsidy of 32.1 yuan per person.The subsidy per visit should be made 50.0 yuan in 201 5.

OBJECTIVETo investigate the insulin-like growth factor-I (IGF-I) gene and polypeptide expression in cultured rat osteoblast (ROB) and the role of IGF-I in mediating the cell-to-cell communication by mimicking the pharmacokinetics of parathyroid hormone (PTH).

METHODSThe ROB was cultured with three kinds of treatment: (1) Control (Ctr), the cells were cultured without PTH during the first 6 hours and the subsequent 42 hours in a 48-hour cycle; (2) Intermittent exposure to PTH (Itm), the cells were cultured with PTH during the first 6 hours, but without PTH in the subsequent 42 hours; and (3) Continuous exposure to PTH (Ctu), the cells were cultured with PTH during the first 6 hours and the subsequent 42 hours.

RESULTSThe bone-forming activities of ROB were increased in Itm and inhibited in Ctu. The IGF-I mRNA content in Itm cells was elevated only during the first 6 hours and that in Ctu cells was elevated at any time during an incubation cycle. The free IGF-I concentration in the medium of Itm cells was generally higher and that of the Ctu cells was generally lower compared with those of the Ctr cells. The IGF-I antibody significantly reduced the alkaline phosphatase activity within the cells of Ctr and Itm.

CONCLUSIONSPTH rapidly and constantly stimulates the IGF-I gene transcription of osteoblast. There was an obvious discrepancy between the IGF-I mRNA content within the osteoblast and the free IGF-I level around the osteoblast in either mode of PTH action. The IGF-I might be important for osteoblast-osteoblast communication and bone-forming activity, not only in intermittent PTH administration, but also in the physiological functioning of osteoblasts.

Objective To study the validity of RAND-UCLA (Rand Corporation and University of California at Los Angeles) consensus panel method in developing guidelines of referral indications for low back pain (LBP).Methods Evidence-based clinical guidelines for LBP management at community level and its referral guidelines published since 2001 and other tools were retrieved with varied tools.All clinical guidelines met inclusion criteria were evaluated with clinical studies and evaluation tools (AGREE).An pool of indication items was established based on evidence for developing referral indications for LBP, which were added by RAND-UCLA consensus panel method, and alternative referral indications were selected and clinical guidelines for LBP referral were established.Results A total of 15 copies of clinical guidelines from nine countries or regions were included in it after critical appraisal.Four copies of referral guidelines from two countries were included.Referral indications for LBP were derived directly from the RAND-UCLA consensus panel process, consisting of 44 referral indications for three groups (immediate, urgent and routine referral).Conclusions The RAND-UCLA consensus panel method is a more useful and practical tool in developing clinical guidelines, referral guidelines, which is worthwhile being recommended and spread.

Objective: To investigate the roles of N-acetyl-L-cysteine (NAC) against binge drinking-induced fatty liver in mice. Methods: SPF male C57BL/6 mice were randomly divided into 3 groups, i.e. control group, model group, and NAC/ethanol group (n=10). Mice in model and NAC/ethanol groups were exposed to 3 doses of ethanol (6 g/kg bw) to induced fatty liver, while mice in control group received equal volume and equal energy of maltodextrin solution. NAC was administered to mice at 1 h before ethanol exposure (100 mg/kg bw, i.p.). The mice were sacrificed at 6 h after the last ethanol exposure. The liver and epididymal adipose tissues were collected. Histopathological examination and biochemical assay kit were used to evaluate the fat accumulation, while Western-blot was performed to detect the protein levels of some key factors involved in fat metabolism in liver and adipose tissues. Results: Compored with control group mice, the liver index and liver weight were significantly increased compared with model group, the liver index and TG level in NAC/ethanol group mice were all significantly decreased (P<0.05). Histological examination showed NAC effectively suppressed binge drinking-induced fat accumulation in mice liver. In addition, NAC had no significant effects on the protein levels of peroxisome proliferator-activated receptor-α (PPAR-α), Acy-CoA oxidase (ACOX), sterol regulatory element binding protein 1 c (SREBP-1c) and fatty acid synthase (FAS). Furthermore, the protein levels of hormone sensitive lipase (HSL) did not significantly differ among 3 groups, whereas NAC prevented binge drinking-induced increase of HSL phosphorylation at ser563 and ser660. Conclusion NAC could effectively attenuate binge drinking-induced fatty liver, which might be associated with the inhibition of lipid mobilization by suppressing the phosphorylation of HSL.

Objective: To investigate the antagonistic effect of diallyl sulfide (DAS) against peripheral nerve injury induced by n-hexane in rats. Methods: A total of 68 adult male Wistar rats were selected, among which 50 were randomly selected and divided into blank control group, DAS control group (100 mg/kg·bw) , n-hexane model group, low-dose DAS intervention group (50 mg/kg·bw) , and high-dose DAS intervention group (100 mg/kg·bw) . A rat model of peripheral nerve injury was established by n-hexane exposure, and the rats were treated with DAS at different doses. The changes in pyrrole adducts and behavior were observed, a metabolic analysis was performed for serum pyrrole adducts, and the intervention effect was evaluated. The remaining 18 rats were randomly assigned to the n-hexane model group, the low-dose DAS intervention group, and the high-dose DAS intervention group, with 6 rats in each group, as satellite groups used for the toxicokinetic analysis of serum pyrrole adducts. Results: Compared with the blank control group, the n-hexane model group and low-and high-dose DAS intervention groups had a significant reduction in body weight since week 2 (P<0.01) . Compared with the n-hexane model group at the end of the experiment at week 7, the high-dose DAS intervention group had a significantly higher body weight (P<0.05) , while there was no significant difference in body weight between the n-hexane model group and the low-dose DAS intervention group (P>0.05) . The n-hexane model group developed gait abnormality at week 2 of poisoning, while the low-and high-dose DAS intervention groups developed gait abnormality at weeks 3 and 5 of poisoning, respectively. At the end of the experiment, the n-hexane model group and the low-and high-dose DAS intervention groups had a significantly higher gait score than the blank control group (P<0.01) . At the end of the experiment, the n-hexane model group and the low-dose DAS intervention group had significantly shorter latency in rotarod test than the blank control group (P<0.01) , while there was no significant difference in latency between the DAS control group and the high-dose DAS intervention group (P>0.05) . Compared with the n-hexane model group, the low-and high-dose DAS intervention groups had a significant increase in latency in rotarod test (P<0.01) . Compared with blank control group, the n-hexane model group and the low-dose DAS intervention group had a significant increase in mean nerve conduction velocity (P<0.01) , while there was no significant difference between the blank control group and the DAS control group or high-dose DAS intervention group (P>0.05) , and compared with the n-hexane model group, the low-and high-dose DAS intervention groups had a significant increase in nerve conduction velocity (P<0.01) . Compared with the blank control group at the end of the experiment at week 7, the n-hexane model group and the low-and high-dose DAS intervention groups had significant increases in the concentration of pyrrole adducts in serum, urine, and hair (P<0.01) , while there was no significant difference between the blank control group and the DAS control group (P>0.05) , and the high-dose DAS intervention group had a significantly lower concentration of pyrrole adducts in serum, urine, and hair than the low-dose DAS intervention group (P<0.05) . Serum pyrrole adducts reached the peak level at 9-12 hours and then started to decrease. Compared with the n-hexane model group, the high-and low-dose DAS intervention groups had a significantly shorter half-life period of serum pyrrole adducts (P<0.01) . Compared with the n-hexane model group, the high-and low-dose DAS intervention groups had a significant reduction in the area under the curve of serum pyrrole adducts (P<0.05) . Conclusion DAS can antagonize peripheral nerve injury induced by n-hexane.
