OBJECTIVE:To provide reference for the rational utilization of narcotic drugs in cancer pain patients. METH-ODS:In retrospective survey,2275 prescriptions of narcotic drugs for cancer pain patients in outpatient and emergency depart-ment of our hospital during 2014-2016 were analyzed statistically in respects of general information,drug amount,consumption sum and DDDs,etc. RESULTS:The proportion of male patients and female patients with cancer pain in our hospital were 65.63%and 34.37% within 3 years,mainly aged 21-90. The consumption amount and sum of narcotic drugs in our hospital increased year by year. Dosage forms were mainly tablet. The consumption amount,sum and DDDs of Morphine hydrochloride sustained-release tablets took up the first places among narcotic drugs. And those of Pethidine hydrochloride injection were the lowest. CONCLU-SIONS:The utilization of narcotic drugs is rational in outpatient and emergency department of our hospital on the whole. Morphine preparations are the predominant analgesic drugs for patients with cancer pain.

Objective To investigate the effects of S100B on the expressions of dopamine receptors and the synthesis,metabolism of neurotransmitters dopamine,5-hydroxytryptamine which are related to the abnormal motor coordination of Parkinson's disease (PD).Methods The hS100B transgenic mice were established.The mice were divided into S100B transgenic group (TG,n =14),S100B knockout group (KG,n =14) and the non-transgenic control group (CG,n =14).The motor coordination ability of mice was measured by the Rota-rod test.The expressions of dopamine D1 receptor (D1DR),dopamine D2 receptor (D2DR),tyrosine hydroxylase (TH) and phosphorylated TH at Ser19,Ser31,Ser40 in brain tissue were detected by reverse transcription polymerase chain reaction and Western blotting.The levels of Tyr,levodopa,dopamine,homovanillic acid,Trp,5-hydroxytryptamine and 5-hydroxyindoleacetic acid in mesencephalon were measured by high performance liquid chromatography with fluorescence detection.Results Compared with CG,the motor coordination ability of mice (s) showed progressive decline in TG (3 months:4.60±0.30vs4.25±0.21,q =5.194;6 months:4.52±0.31 vs4.07±0.22,q =6.139;9 months:4.43 ± 0.25 vs 3.60 ± 0.18,q =13.484;all P ＜ 0.05),the expressions of D2DR mRNA and protein decreased (1.34 ± 0.13 vs 0.48 ± 0.07,q =21.578;1.05 ± 0.15 vs 0.69 ± 0.10,q =8.063,both P＜0.05) and phosphorylated TH at Serl9 and Ser40 increased (0.95 ±0.10 vs 1.14-0.13,q =4.972;0.94 ± 0.12 vs 1.17 ± 0.14,q=5.382,both P＜ 0.05),the levels of levodopa,dopamine and homovanillic acid were elevated (87.04 ± 11.77 vs 115.28 ± 16.80,q =4.764;56.66 ± 9.87 vs 72.96 ± 11.02,q=3.923;26.58 ± 8.11 vs 38.65 ± 6.67,q=3.981,all P＜ 0.05),the leve1 of 5-hydroxytryptamine was reduced (925.50 ± 74.26 vs 637.87 ± 56.76,q =11.084,P ＜ 0.05),the ratios of homovanillic acid/dopamine and 5-hydroxyindoleacetic acid/5-hydroxytryptamine increased (0.45 ± 0.05 vs 0.54±0.08,q =3.325;0.94±0.07 vs 1.42±0.12,q =12.367,both P＜0.05) in the brain of TG at the age of 9 months old.There was no significant difference of detection indexes between KG and CG.Conclusions S100B plays an important role in the development of PD and the brain-specific S100B transgenic mice can be used to investigate the function of S100B gene on the development of PD.

The content of benzyl isothiocyanate (BITC) which as the enzymatic hydrolysis product of benzyl glucosinolate through thioglucosidase was determined by HPLC. The content of benzyl isothiocyanate (BITC) which as the enzymatic hydrolysis product of benzyl glucosinolate through thioglucosidase was determined by HPLC. The chromatography condition was as follows: Kaseisorb LC ODS 2000 (4.6 mm x 150 mm, 5 min) column with the mobile phase of acetonitrile(A)-water( B) under gradient elution (0-5 min, 3%-8% A; 5-9 min, 8%-48% A; 9-23 min, 48%-62% A; 23-28 min, 62%-99% A); the flow rate was 1.0 mL x min(-1) with 10 microL injection volume; detection wavelength was 246 nm and temperature of column was 40 degrees C. The content of benzyl glucosinolate was in the range of 10.76-17.91 g x L(-1). The method is simple, accurate and good reproducibility which can be used for the determination of benzyl glucosinolate in Lepidium meyenii, effectively.

Objective To prepare a bionic artificial bone scaffold using a room temperature three dimensional (3D) printing technique and evaluate its biocompatibility and bioactivity in vitro.Methods A room temperature 3D printing technique was applied to fabricate 3D bionic artificial bone scaffolds using collagen/hydroxyapatite.The physico-chemical structure,porosity and mechanical strength of the scaffolds were assessed.The extract liquid of scaffolds was cocultured with bone mesenchymal stem cells (BMSCs) to evaluate the toxicity of scaffolds.There were 3 experimental groups:blank control with no scaffolds,printed scaffolds group and non-printed scaffolds group.The condition of BMSCs on the scaffolds was observed via scanning electron microscopy(SEM) and immunostaining.3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay and SEM were applied to monitor the proliferation of BMSCs on the scaffolds.At last,alkaline phosphatase (ALP) activity and mRNA expression levels of osteogenesis-related genes were detected to assess the osteoinductive property of the scaffolds.Results The 3D printed scaffolds fabricated in the present study were characterized by highly interconnected pores which were controllable and even in size.The cross section of the scaffolds presented an irregular honeycomb-like microstructure.The porosity of printed 3D scaffolds (71.14％ ± 2.24％) was significantly higher than that of non-printed scaffolds (59.04％ ±2.98％) (P ＜ 0.05).The physico-chemical structures of the materials were preserved after printing without additional cytotoxicity.The MTT results at 7 and 14 days revealed that the printed scaffolds had a significantly more cell numbers than the non-printed scaffolds(P ＜ 0.05).SEM showed that the BMSCs adhered well onto the printed scaffolds and proliferated and migrated through the pores.Compared with the blank control,the printed scaffolds showed obviously better osteogenic outcomes.Conclusion The 3D bionic artificial bone scaffolds of collagen/hydroxyapatite manufactured by a room temperature 3D printing technique can provide a good extracellular matrix for BMSCs to proliferate and differentiate.

Objective To identify differences in the anal sphincter surface electromyography (sEMG)variables in spinal cord injury (SCI) subjects with different severities. Methods One hundred and ten SCI patients' impairments were classified as ASIA A,B,C or D using the International Standards for the Neurological Classification of Spinal Cord Injury.The evaluation was pedormed using sEMG equipment with an inserted anal sensor electrode and the Glazer pelvic floor muscle sEMG protocol.The sEMG variables were recorded and compared. Results There was no significant difference in sEMG variables between groups A and B,but the mean and maximum sEMG values of groups C and D in flick contractions ( 1 s),tonic contractions ( 10 s),and endurance contractions (60 s) were significantly higher than those of group A.Compared with group C,the mean and maximum sEMG values of group D were all significantly higher. Conclusions The sEMG data from the anal sphincter during contractions decreases significantly after SCI.Glazer's pelvic floor muscle sEMG protocol is a noninvasive and convenient real-time assessment.It is a useful complementary tool for quantitative assessment of the pelvic floor muscles of SCI patients.

Designed the degenerate primers of alcohol dehydeogenase and L-lactate dehydrogenase to aug- ment Ethanoligenens harbinense B49 genomic DNA, and obtained about 780 bp and 610 bp PCR product respectively. Augmented flank sequences of the two PCR fragments with the Cassette PCR method. Similar- ity alignment showed that the products of the cloned DNA were very high similar to those of alcohol dehy- drogenase genes and L-lactate dehydrogenase genes respectively. One of the two sequences was 1902 bp long, and the ORF of adh was 1101 bp long and encoded 366 amino acids. Its putative molecular weight was about 39.71 kD, its calculational isoionic point was pH 5.93. The maximal identity and positive was 51% and 73% with Clostridium thermocellum ATCC 27405 adh. The other one was 2490 bp long, and the ORF of adh was 951 bp long and encoded 316 amino acids. Its putative molecular weight was 34.23 kD, its calcula-tional isoionic point was pH 6.09. The maximal identity and positive was 55% and 74% with Bacillus megaterium L-ldh. Successfully cloning these two genes would not only enrich the gene resources of L-lactate dehydrogenase and alcohol dehydrogenase genes, but also give the scientific warrant for the meta- bolic engineering research and the construction of the gene-engineering bacteria.
