OBJECTIVETo observe the supplementary analgesic effect of electroacupuncture and its influence on the maintenance of anesthesia and the speed of recovery of patients undergoing craniotomy.

METHODSEighty cases of supratentorial tumor resection were randomly divided into group A and group S, 40 cases in each group. All the patients were anesthetized with 2% Sevoflurane. The patients in group A received electroacupuncture at Hegu (LI 4) and Waiguan (TE 5), Jinmen (BL 63) and Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40) from anesthesia beginning to the end of operation, and in group S without electroacupuncture. The end-tidal Sevoflurane concentration, minimum alveolar concentration (MAC), bispectral index (BIS) and the information during anesthesia recovery stage were recorded, respectively.

RESULTSThe end-tidal concentration and MAC of Sevoflurane in group A at all times were significant lower than those in group S (P<0.05, P<0.01) with a Sevoflurane saving of 9.62% on average. The BIS in group A during a few phases were higher than that in group S (all P<0.05). During anesthesia recovery stage, the time of each phase in group A was significantly shorter than that in group S (all P<0.01). No dysphoria and one case with nausea and vomiting were shown in group A, but in group S, 2 patients had dysphoria and 3 patients had nausea and vomiting.

CONCLUSIONElectroacupuncture combined with Sevoflurane anesthesia can decrease the dosage of Sevoflurane, shorten the recovery time of anesthesia and improve the quality of anesthesia recovery of the patients undergoing resection of supratentorial tumor.

OBJECTIVETo investigate the association between the exons 2 to 4 of the MICA gene and ankylosing spondylitis (AS).

METHODSBy PCR-SSOP, DNA samples from 56 AS patients and 112 random healthy individuals, as normal control were genotyped to analyse the polymorphism in exons 2, 3, 4 of the MICA alleles.

RESULTSMICA*008 was dominant in MICA allele,accounted for 32.14% and 30.36% in AS patients and normal controls respectively. The frequency of MICA*007 was significantly increased in AS patients, when compared with normal controls (chi-square=10.18, P<0.05, RR=2.50). No difference was found in the other MICA alleles. The haplotype analysis revealed that there were the strong linkage disequilibrium between MICA and HLA-B of AS patients, and normal controls. There was a difference in MICA*007-B27 between two groups (chi-square=18.46, P<0.05, RR=7.47). Both HLA-B27 and MICA*007 were strongly associated with AS. Stratified analysis showed that HLA-B27 was significantly relative to AS,while it was not found between MICA*007 and AS.

CONCLUSIONThe increased frequency of MICA alleles may be due to its strong linkage disequilibrium with HLA-B27.

In order to study the distribution of virulence genes of Listeria monocytogenes (Lm) in Hebei Province,29 virulence genes of Lm,including Listeria monocytogenes pathogenicity islands Ⅰ (LIPI-Ⅰ:prfA,plcA,plcB,hlyA,mpl and actA),10 internalins genes (inlA,inlB,inlC,inlD,inlE,inlF,inlG,inlH /C2,inlI and inlJ) and the other 13 virulence-associated genes (bsh,srtA,iap,sigB,virR,mprF,dltA,dltB,dltC,dltD,srtB,fbpA and hpt) were detected by PCR.Results showed that in the 91 Lm strains,the detection rate of 23 virulence genes were 100％.The 29 virulence genes of 26 Lm strains were all detected,and 65 Lm strains had different deletion of 6 virulence genes inlD,inlF,inlG,inlH /C2,inlJ and mpl.The deletion rate of inlG and inlF were 60.44％ and 54.95％,respectively,following by mpl gene,with a deletion rate of 19.78％.According to the absence of virulence genes,91 strains could be divided into 10 subtypes,and the dominant virulence subtypes was type Ⅰ with all 23 virulence genes.The deletion rate of virulent genes in Shijiazhuang was higher than that in northern Hebei.It is suggested that the rate of virulence gene of food-borne Lm in Hebei Province is high,and the virulence gene deletion patterns has diversity and regional differences.

OBJECTIVETo establish a new method for the determination of fangchinoline and tetrandrine in Stephania tetrandra and Fengtongan capsule by noanqueous capillary electrophoresis.

METHODSeparation was carried out in an uncoated fused capillary (50 cm x 75 microm i.d.) with a running buffer containing 50 mmol x L(-1) ammonium acetate, 1.0% acetic acid and 20% acetonitrile in methanol. A separation voltage of 20 kV and a UV detector wavelength at 214 nm were adopted. Sample was introduced from the anode.

RESULTThe calibration ranges were 1.00, 500 mg x L(-1) for both analytes. Under the optimum conditions, the relative standard deviation (RSD, n = 6) for the migration time of each analyte were 0.09%, 1.9% (intra-day) and 0.63%, 1.9% (inter-day); The RSD for the peak area of each analyte were 0.45%, 5.9% (intra-day) and 2.3%, 5.6% (inter-day), respectively. The contents of the analytes were determined easily with average recoveries 102% for fangchinoline and 105% for tetrandrine in S. tetrandra and 94.6% for fangchinoline and 98.7% for tetrandrine in Fengtongan capsules, respectively.

CONCLUSIONThe proposed method is simple, rapid, accurate and higher repeatable, and can be used to control of the quality of S. tetrandra and Fengtongan capsules.

OBJECTIVEVariable Number of Tandem Repeats (VNTRs) analysis was a recently developed method which could serve as a 'real-time' genotyping tool for Mycobacterium tuberculosis. One hundred and thirteen M. tuberculosis isolates from the patients with tuberculosis in Beijing were analysed using the reference method to study the characters of genetic diversity and genotype.

METHODSThirteen tandem repeat loci (ETR-A, ETR-C, ETR-D, MIRU10, MIRU16, MIRU27, MIRU31, MIRU40, Mtub21, Mtub30, Mtub38, Qublla, Qubllb) in the total genome of MTB were analyzed by PCR and agarose gel electrophoresis method. The characters of the polymorphism of DNA fingerprinting of one hundred and thirteen MTB strains were analyzed with Gel-Pro analyzer 3.1 software and BioNumerics 3.0 software. Results One hundred and thirteen MTB strains were characterized and classified in to four genotype families(type I , type II , type NV, type V ) based on thirteen tandem repeat loci. One hundred and four isolates(92.0%) belonged to type I , the other three genotypes scattered, five strains(4.4%) remaining with type II , while type IV and type V having the same quantity 1.8% (2/113). M. tuberculosis H37Rv belonged to a unattached genotype(type ll ). Conclusion There was obvious length polymorphism in the M. tuberculosis isolates which implied that type I was the epidemic strain clusters in M. tuberculosis in Beijing. VNTRs analysis seemed to be a simple, rapid, sensitive and valuable tool for epidemiological studies of M. tuberculosis complex organisms.

OBJECTIVETo study the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property by observing the action characteristic of 10 traditional Chinese medicines capable of promoting blood circulation and removing blood stasis with neutral property in the microcirculation in rats with heat stagnation and blood stasis syndrome.

METHODThe rat model with heat stagnation and blood stasis syndrome was established by injecting carrageenan and dry yeast, and the rat model with cold stagnation and blood stasis syndrome was built by the body freezing method. Ten traditional Chinese medicines with neutral property, including 5 with hot property and 5 with cold property, were selected for intervention to observe blood flow rate and flow state indicators in rat auricles and make a comparative analysis on action characteristics of traditional Chinese medicines with neutral property.

RESULTANOVA showed that among the 10 traditional Chinese medicines with neutral property, 6 such as Typhae Pollen, Sappan Lignum and Vaccariae Semen can obviously increase the blood flow rate (P < 0.01 or P < 0.05) in the above two models; all of the 5 traditional Chinese medicines with cold property can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat model with heat stagnation and blood stasis syndrome, but only Salvia miltiorrhiza can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, while other medicines showed no notable effect; among the 5 traditional Chinese medicines with hot property, Carthamus tinctorius and Ligusticum chuanxiong can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, but had no obvious effect to the blood flow rate in the rat models with heat stagnation and blood stasis syndrome. According to the analysis on average blood flow rate, traditional Chinese medicines with natural and cold properties showed similar effect on heat stagnation and blood stasis syndrome and better effect in increasing blood flow rate than those with hot property; those with natural and hot properties showed similar effect and better effect in increasing blood flow rate than those with cold property.

CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with those with cold property; wile under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with the Chinese medicinal herbs with hot property. This indicates the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property to some extent.

OBJECTIVETo investigate the incidence of malignant tumors among fluoride-exposed workers in aluminum industry.

METHODSSampling points were set in the working positions at different radii around an workshop for treating the waste gas from aluminum electrolysis, and the concentrations of fluoride ions, aluminum, and benzo[a]pyrene (B[a]P) in air were measured by electrode method, atomic absorption spectrophotometry, and high performance liquid chromatography, respectively. The incidence of tumors among the workers in the aluminum plant from 1995 to 2009 was investigated by questionnaires and medical records and then statistically analyzed.

RESULTSThere was a negative correlation between the concentrations of fluoride and aluminum and the radius around the fluoride source at each sampling point. B[a]P was not detected at each sampling point. The crude incidence rate of tumors among factory workers was 117.95/100 000 (standardized rate = 58.81/100 000); the standardized incidence rate of tumors was higher in female workers than in male workers (male-to-female ratio = 1:2.64). The peak age of onset of tumors was 40 ∼ 49 years. The most and second most common tumors were liver cancer and lung cancer in male workers and breast cancer and lung cancer in female workers. Compared with the unexposed population in the city where the aluminum plant was located, the female fluoride-exposed workers had an increased tumor incidence, 2.14 times that of the city's average level, and the fluoride-exposed workers had a younger age of onset of tumors and approximately the same types of tumors.

CONCLUSIONFluoride exposure may lead to an increasing trend in tumor incidence among female workers in aluminum industry.

OBJECTIVETo further study the characteristics of drugs with neutral property in two-way application and conditioned dominance by observing the action characteristic of 10 traditional Chinese medicines with neutral property in hemorheological indicators of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats.

METHODThe model of heat stagnation and blood stasis syndrome rats was established by injecting carrageenan and dry yeast, while the model of cold stagnation and blood stasis syndrome rats was established by body freezing. Subsequently, 10 traditional Chinese medicines with neutral property, 5 traditional Chinese medicines with heat property and 5 traditional Chinese medicines with cold property were selected for intervention to observe the changes in such indicators as whole blood viscosity, plasma viscosity and hematocrit and analyze the action characteristics of drugs with neutral property.

RESULTANOVA showed that among six of the 10 traditional Chinese medicines with neutral property, including Typhae Pollen, Sarcandrae Herba and Sappan lignum, could obviously increase the hemorheological indicators of both heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats; five traditional Chinese medicines with cold property, such as Salviae Miltiorrhizae Radix et Rhizoma, Leonuri Herba, Rhei Radix et Rhizoma, could significantly ameliorate the hemorheological indicators of heat stagnation and blood stasis syndrome rats (P < 0.01 or P < 0.05), and Salvia Miltiorrhiza Radix et Rhizoma alone could ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.05); all of the five traditional Chinese medicines with heat property could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.01), among which Carthami Flos and Notoginseng Radix et Rhizoma could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats. According to the average high-shear blood viscosity analysis, drugs with neutral property showed similar action characteristics to those with cold property in ameliorating hemorheology indicators of heat stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity; and traditional Chinese medicines with neutral property have the similar action characteristics to those with heat property in improving the hemorheology indicators of cold stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity.

CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with cold property; but under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with heat property. This indicates that traditional Chinese medicines with neutral property show both heat and cold properties under he conditions of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome.
