		                        			Chloral hydrate is a safe and effective sedative hypnotic medicine. Patients can usually calm down or fall asleep quickly after taking it. It has great clinical value and practical needs in children ’s sedation. However ,the nature of chloral hydrate itself and various factors such as ambient temperature and light affect its stability of the preparation ,most of chloral hydrate preparations are still used in clinic in the form of hospital preparations. Therefore ,developing chloral hydrate preparation with single dose ,long validity period and automatic mass production is the prospect and goal of its subsequent development. Based on it,this study collects and reviews the relevant literatures on various preparations of chloral hydrate and their clinical application by searching the Chinese and English databases.

		                        			OBJECTIVE To establish the fingerprint of Huatan qushi huoxue decoction (HQHD),and to explore the effects of processing and decoction methods on its components. METHODS Using salvianolic acid B as reference ,HPLC fingerprints of 10 batches of single and mixed decoction of crude drugs ,single and mixed decoction of processed products (original formula referred to 8 ingredients were crude drugs ;processed formula referred to processed products of Alisma orientale ,Salvia miltiorrhiza , Curcumae Radix and Bupleuri Radix ,and crude drugs of other ingredients ;single decoction referred to the mixing of each ingredient after being decocted separately ;mixed decoction refers to decocting after mixing all ingredients )were stablished by Similarity Evaluation System of Chromatographic Fingerprints of Traditional Chinese Medicine (2012 edition). The similarity evaluation,common peak identification and attribution ,chemical pattern recognition analysis were also carried out. RESULTS There were 37 common peaks in each fingerprint of 10 batches of single and mixed decoction of crude drugs ,single and mixed decoction of processed ,the similarities with control fingerprint were higher than or close to 0.950. Nine common peaks were identified,i.e. rutin (peak 12),hesperidin(peak 13),salvianolic acid B (peak 16),quercetin(peak 20),silybin(peak 22), luteolin(peak 23),autrantio-obtusin(peak 29),23-acetylalismol C (peak 34),saikosaponin b 2(peak 35);decoction pieces of 8 ingredients all contributed to the fingerprints of HQHD. Principal component analysis (PCA)showed that the 4 kinds of HQHD samples were grouped into one category ,respectively. The clustering result of partial least squares-discriminant analysis was consistent with that of PCA. Corresponding components of peak 1,15,17,18 and 36,salvianolic acid B and luteolin m ay be the differential markers of the quality for mixed decoction samples of crude drugs and processed products ; corresponding components of peak 1,7,17-19,salvianolic acid B and hesperidin may be the differential markers of the quality for single decoction samples of crude drugs and processed products;corresponding components of peak 1,17-19,36, salvianolic acid B and luteolin may be the differential markers of the quality for single decoction and mixed decoction samples of crude drugs ;corresponding components of peak 7,17-19,21, hesperidin,salvianolic acid B ,rutin,luteolin and autrantio-obtusin may be the differential markers of the quality for single decoction and mixed decoction samples of processed products. CONCLUSIONS The established fingerprint of HQHD is stable and reliable. The quality differential components of different decoction samples are luteolin ,hesperidin,etc. The quality differential components of samples processed or not are rutin ,hesperidin,autrantio-obtusin,etc.

		                        			ObjectiveOn the basis of sensory evaluation, the changes of volatile components in gecko before and after processing were compared, and the odor correction effect of different processing methods of gecko was discussed. MethodRaw products, fried yellow products, vinegar processed products, wine processed products, talcum powder scalding products and white wine sprayed products after scalding talcum powder of gecko were prepared, and 10 odor assessors were invited to evaluate the 6 samples in turn by sensory evaluation. Headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) and relative odor activity value (ROAV) were used to analyze the key odor components, and multivariate statistical methods were used to analyze the difference of volatile components between raw and processed products of gecko. Taking water-soluble extract and protein contents as internal indicators, sensory evaluation score and content ranking of differential components as external indicators, and assigning a weight of 0.25 to them respectively, the comprehensive scores of raw products and processed products of gecko were calculated to evaluate the odor correction effect of each processing method. ResultThe average sensory evaluation scores of the raw products, fried yellow products, vinegar processed products, wine processed products, talcum powder scalding products and white wine sprayed products after scalding talcum powder of gecko were 1.6, 5.2, 6.2, 6.1, 7.2 and 8.0, respectively. ROAV results showed that key components affecting odor of gecko were 2-ethyl-3,5-dimethylpyrazine, isovaleraldehyde, trimethylamine, 1-octen-3-ol, n-octanal, nonanal, 2-methylnaphthalene, γ-octanolide, 2-heptanone and phenol. Principal component analysis (PCA) significantly distinguished raw products from processed products. Orthogonal partial least squares-discriminant analysis (OPLS-DA) results showed that there were 16, 13, 16, 16, 16 differential components between raw products, fried yellow products, vinegar processed products, wine processed products, talcum powder scalding products and white wine sprayed products after scalding talcum powder of gecko. Among these differential components, there were 4 common components, namely, the contents of different odor components (2-methylnaphthalene and 2-ethyl-p-xylene) decreased, while the contents of different flavor components (2-decanone and 2,3,5-trimethylpyrazine) increased. The comprehensive scoring results showed that the odor correction effect of each processed products was in the order of talcum powder scalding products>wine processed products>vinegar processed products>fried yellow products>white wine sprayed products after scalding talcum powder. ConclusionTalcum powder scalding is a better method to improve the odor of gecko, and it can provide an experimental basis for the processing of gecko to correct the odor.

Methods A total of 117 patients with cervical cancer who underwent surgical treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to January 2017 were selected and randomly divided into control group (n=58) and observation group (n=59) by the random number table method. Routine nursing was given to both groups, on the basis of which the observation group adopted nurse-patient's co-participation management method to exercise the bladder function, and the recovery status of cervical cancer patients' bladder function after surgery was compared between the two groups. Results The residual urine volume of the observation group was less than 100% and the proportion of spontaneous urination was significantly higher than that of the control group. The proportion of reattached catheter was significantly lower than that of the control group (P<0.05). The patients in the observation group had less exhaust time and fewer hospitalization days than the control group, and the difference was statistically significant (P< 0.05). The incidence of urinary retention in the observation group (8.47%) was significantly lower than that in the control group (20.69%), and the first extubation success rate of the observation group (91.52%) was significantly higher than that of the control group (63.79%), with a statistical difference (P<0.05). Conclusions The nurse-patient's co-participation can improve the effect of postoperative bladder function recovery in patients with cervical cancer, and significantly reduce the incidence of complications.

OBJECTIVETo induce Mycobacterium tuberculosis (MTB) resistance with ofloxacin (Ofx) of stepwise increasing concentration in vitro, investigate stability to fluoroquinolone (FQs) antibiotic of MTB, and analyze the molecular mechanism and mutation specialty of drug resistance preliminarily.
METHODSMTB Standard strain H37RV and 24 clinical isolates susceptible to Ofx were selected and experimentally serially subcultured in liquid culture medium containing increasing concentration of Ofx and induced the drug resistance to Ofx. Variety of Minimal Inhibitory Concentrations (MICs) to FQs drugs were detected by microwell-MIC-test method. Mutations of quinolone resistance determining region (QRDR) of gyrA gene were sequenced and identified. Relationship of different mutation sites and drug resistant degree were analyzed. A total of 6 MTB clinical isolates resistant to Ofx and induced drug resistant isolates in vitro were serially subcultured in liquid culture medium without drug. Variety of drug resistant stability, including MIC and mutation of gyrA gene were detected.
RESULTSMIC values of 21 Ofx susceptible isolates after induction were eight times higher than before, which were induced to drug resistant strains successfully and also resistant to Lfx and Mfx. Hot mutations of QRDR of gyrA gene were detected by sequencing, except one strain. Mutation of codon 94 occurred in 60% (12/20) of the strains with mutations and corresponding value of 50% Minimal Inhibitory Concentrations(MIC50) was ≥ 8 µg/ml. In all, 4 of 6 MTB clinical isolates resistant to Ofx harbored mutation of codon 90 (67%) , but the corresponding value of MIC50 was 2 µg/ml. After 21 serially subcultured in liquid culture medium without drug, MIC values of 6 clinical isolates resistant to Ofx were not changed obviously and mutations were also not changed. After 11 times serially subcultured in culture medium without drug, MIC values of induced drug resistant strains were also not changed obviously, but new mutations were detected in QRDR of 3 isolates.
CONCLUSIONMTB strains resistant to three kinds of FQs antibiotic were obtained by induction in vitro with Ofx. Codons 88, 94 mutations of QRDR of gyrA gene were related to the high level FQs drug resistance of MTB. Drug resistant stability of MTB to FQs was strong, and it is difficult for MTB to resume susceptibility.

		                        			Objective To investigate mutations in immediate early ( IE) gene ORF62 of three var-icella vaccine Oka strains ( vOka ) including two strains produced in China and their parental Oka strain (pOka), and then to further elucidate its possible roles in attenuation mechanism by comparing their ORF 62 promoter sequences and its activities , ORF62 coding regions and its transactivities .Methods ORF62 pro-moter-reporter plasmids and ORF62-expressing plasmids of pOka and three vOka strains ( vOka-BK from Changchun BCHT Biotechnology Co ., vOka-SH from Shanghai Institute of Biological Product Co .Ltd., and vOka-GSK from GlaxoSmithKline plc, as control) were constructed, respectively.ORF62 promoter regions and coding regions of the four strains were sequenced and then compared with each other .Differences of ac-tivities of the ORF62 promoter, and transactivities of the ORF62-encoded IE62 upon immediate early (ORF4), early (ORF28) and late (ORF67) gene promoters between pOka and vOka strains were assayed with transient transfection technique .Results Compared with pOka strain , three vOka strains had a con-sistent T deletion mutation at site 110 050 in ORF62 promoters, which did not result in any change of tran-scription factor binding motif .However , activities of ORF62 promoters from three vOka strains were signifi-cantly lower than those of pOka strain .Three consistent substitution mutations were observed in ORF 62 cod-ing regions of three vOka strains and three new enzyme restriction sites including SmaⅠ, NaeⅠand BssHⅡwere generated, respectively.Transactivities of IE62 from three vOka strains upon ORF4, ORF28 and ORF67 promoters were significantly higher than those of pOka both in CV-1 and MeWo cells , except that vOka-SH IE62 showed significantly lower transactivities upon ORF 4 promoter than those of pOka strain in CV-1 cells.Conclusion Consistent T deletion mutation at site 110 050 in ORF62 promoters of three vOka strains might be responsible for the reduced promoter activities and the changes of IE 62 transactivities .How-ever , it seemed that cell types have no significant effect on ORF 62 promoter activity or IE 62 transactivity be-tween pOka and vOka strains .

		                        			Objective To establish a novel method to screen for anti-varicella-zoster virus (VZV) compounds with our previously generated reporter cell line for VZV, MV9G. MethodsMV9G cells were directly infected with cell-free virus of Oka vaccine strain (vOka) for 2 hours( CFV direct-infection) or cocultured with vOka-infected MeWo cells containing cell-associated virus for 48 hours (CAV co-culture) to promote expression of the reporter gene firefly luciferase. Antiviral compounds including heparin, mannose-6-phosphate( M-6-P), acyclovir( ACV ), resveratrol and roscovitine were added in the medium before or after the virus infection. Inhibitory effects( IC50 ) of the antiviral compounds were analyzed by comparing firefly luciferase activities of MV9G cells in the presence of antiviral compounds with those in the absence. Results Antiviral compounds inhibited luciferase activities of MV9G cells activated by CFV direct-infection and/or CAV co-culture in different levels. The reductions of luciferase activities statistically correlated with those of viral foci shown by immunostaining with a monoclonal antibody against VZV immediate early 62 antigens (IE62) in controls. Among these compounds, heparin, M-6-P, and 2.5 μmol/L of roscovitine inhibited CFV-activated more strongly than CAV-activated luciferase activities, whereas ACV and resveratrol inhibited CAV-activated more strongly than CFV-activated luciferase activities. Cell-associated ACV-resistant strains,Kanno and rOka YSR, activated luciferase activities of MV9G cells, too. However, the inhibitory concentrations (IC50) of ACV to the ACV-resistant strains were much higher than those to the ACV-sensitive strains,pOka and CaGu. ConclusionThe CFV direct-infection and CAV co-culture assays were useful to screen for antiviral compounds targeting the early and late phases of VZV infection, respectively. The VZV reporter cell-based assays may provide a simple, rapid, sensitive, and high-throughput method to screen for anti-VZV compounds.

		                        			Objective To investigate correlation between the results of drug susceptibility and the extent of drug-resistances in Mycobacterium tuberculosis clinical isolates. Methods Liquid culture and MTT test were used. Twelve anti-TB drug MICs and drug susceptibility testing of the 163 MTB strains from random clinical isolates were detected, which including RFP, INH, SM, EBM, OFLX, LVFX, MOX, AMK,CPM, PTA, CLA and PAIN. Results There are 67% (42/62) Mycobacterium tuberculosis strains resistant to SM, 63% (51/81) Mycobacterium tuberculosis strains resistant to INH, 77% (50/65) Mycobacterium tuberculosis strains resistant to RFP, 41% ( 15/37 ) Mycobacterium tuberculosis strains resistant to AMK,41% (12/29) Mycobacterium tuberculosis strains resistant to CPM, 20% (12/60) Mycobacterium tuberculosis strains resistant to EMB and 43% (25/58) Mycobacterium tuberculosis strains resistant to OFLX which MICs were equal to or more than 16 μg/ml, 8 μg/ml, 8 μg/ml, 16 μg/ml and 4 μg/ml, 4 μg/ml and 8 μg/ml,respectively. There were significant differences in the MICs of OFLX, LVFX and MOX in OFLX resistant strains (2-128, 1-32 and 0.0625-1 μg/ml, respectively) by ANOVA ( F = 16.874, P < 0.001 ). The MICs of SM, INH, RFP, EMB, OFLX, AMK and CPM in isolates resistant to six or seven drugs (0.5-128,2-64,0.25-128,1-32,1-64,0.5-128 and 1-128 μg/ml,respectively) were higher than those (0.25-128,0.0625-64,0.25-32,0.25-2,0.125-2,0.5-4 and 1-4 μg/ml,respectively) in isolates resistant to one or two drugs (F=20.066, 40.499, 47. 197, 70.373, 91.432, 41.840 and 21.547, respectively, P <0.05). The MICs of SM, INH, RFP and EMB in isolates resistant to four drugs (1-128,2-64,0.25-128 and 1-32 μg/ml,respectively ) were higher than those ( 0.25-128,0.0625-64, 0.25-64 and 0.25-2 μg/ml,respectively) in isolates resistant to one or two drugs (F = 26.242, 23.563, 31.541 and 64.469,respectively, P <0.05).The MICs of RFP in MDR isolates (2-64 μg/ml) were higher than those (0. 25 μg/ml) in other resistant isolate except M DR isolates (F = 5.613, P <0.05). Conclusions The study shows that there are associations between the results of routine drug susceptibility testing and the resistant extent of anti-TB drugs. This could help doctors select more effective anti-TB regimen for TB patients according to the correlations.
