OBJECTIVETo compare the efficacy differences between acupoint catgut-embedding combined western medicine (ACCWM) and simple western medicine (WM) for treatment of epilepsy of generalized seizures type.

METHODSFifty-two patients with epilepsy of generalized seizures type were randomly divided into an ACCWM group (n=30) and a WM group (n=22). Dazhui (GV 14), Yaoshu (GV 2), Jiuwei (CV 15), Qihai (CV 6) were selected in the ACCWM group as the main acupoints combined with routine antiepileptic drugs, Valpromide was taken orally, 2.0 g/d for adult, 50 mg/kg x d for child. The WM group was treated with routine antiepileptic drugs. The epilepsy score and the attack frequency one year before the treatment and one year during treatment were observed and the therapeutic effects in the two groups were compared.

RESULTSThe epilepsy score and the attack frequency were both decreased in the two groups (P<0.01, P<0.05), and the epilepsy score in the ACCWM group decreased significantly (6.57 +/- 3.29 vs 10.73 +/- 2.54, P<0.05). The total effective rate of 90.0% (27/30) in the ACCWM group was superior to that of 68.2% (15/22) in the WM group (P<0.05).

CONCLUSIONThe therapeutic effect of ACCWM is superior to that of simple western medicine in treating epilepsy of generalized seizures type. It can improve significantly the attack symptoms so as to enhance life quality of the patients with epilepsy.

OBJECTIVETo study the genetic pathogenesis of myasthenia gravis (MG) caused by cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene polymorphisms and regulation function of transcription factor.

METHODSELISA assay was used to determine the expression level of serum sCTLA-4 in MG. Four single nucleotide polymorphisms (SNPs) of CTLA-4 at exon 1 +49, promoter -318, -1661, -1772 were analyzed by restriction fragment length polymorphism (RFLP). Transcription factor nuclear factor 1(NF-1) and c/EBPbeta binding site were confirmed by chromatin immunoprecipitation(CHIP) assay.

RESULTSIt was found that the frequencies of the GG+49 genotype and G+49 allele are higher in MG patients with thymoma than those in patients of thymic hyperplasia and normal thymus subgroups. T/C-318 is not correlated with MG. The frequency of CT-1772 genotype is significantly higher in MG patients, especially in MG patients with thymoma, when compared with that in healthy controls. Meanwhile, the frequency of the G-1661 allele and GG-1661 genotype is lower in MG patients. Linkage disequilibrium (LD) between each SNPs in promoter -1772, -1661, -318 and coding sequence 1 (CDS 1) +49 is apparent. sCTLA-4 levels in patients' sera are correlated with the haplotype and genotype. T/C-1772 and A/G-1661 SNPs change the sequence of transcription factor NF-1 and c/EBPbeta binding sites. DNA variants lose site-specific binding activity of transcription factor regulated by lectin ConA and PHA.

CONCLUSIONThere are strong positive linkages among four SNPs. C/T-1772 and A/G-1661 polymorphisms can result in inefficient transcription of CTLA-4 gene. T>C-1772 mutation also affects gene splicing. These SNPs may constitute a factor of susceptibility to disease.

OBJECTIVETo study the correlation between the lung pixel indexes of multi-slice spiral CT (MSCT) and pulmonary function test (PFT), and to explore the CT features of histograms of lung attenuation.

METHODSMSCT scan and pulmonary function test (PFT) were separately performed in 127 subjects within one week. The total lung was scanned with MSCT at full inspiration, full expiration, and normal respiration. The lung pixel indexes were measured by Pulmo pulmonary quantitative software. These indexes include PI(-910Huin), PI(-960HUEX), PI(-910Huin), PI(-960Huex), PI(-910(Hun), PI(-960Hun), PI(910Huex/in), and the histograms of lung attenuation.

RESULTSCorrelation existed between all the lung pixel indexes of MSCT and PFT. PI(-910Huex/in showed the best correlation with FEV1/FVC (r = 0.901, P < 0.01). Three distribution patterns were found in the histograms of lung attenuation of total lung, including double-peak distribution (n = 28), similar normal distribution (n = 81), and partial distribution (n = 18).

CONCLUSIONThe lung pixel indexes of MSCT have significant correlation with PFT and can be used to assess the pulmonary function.

OBJECTIVETo observe the efficacy difference between meridian cosmetology and western medicine in the treatment of chloasma and explore the impacts of meridian cosmetology on E2 and PRGE.

METHODSThree hundreds cases of chloasma were randomized into a meridian cosmetology group and a western medication group according to the visit sequence, 150 cases in each one. In the meridian cosmetology group, the meridian regulation, acupuncture based on pattern/syndrome differentiation [at the body acupoints such as Qihai (CV 6), Xuehai (SP 10), Zusanli (ST 36), Sanyinjiao (SP 6), Ganshu (BL 18), Pishu (BL 20) and Shenshu (BL 23), etc.] and the local surrounding needling therapy on the chloasma skin lesion were adopted. In the western medication group, the oral administration of Vitamin C and E was prescribed for 3 months. The clinical efficacy was observed for the patients in the two groups. Additionally, 30 cases were collected from the meridian cosmetology group randomly for the detection of estrogen (E2) and progestin (PRGE) before and after treatment.

RESULTSThe effective rate in the meridian cosmetology group was 92.6% (126/136), which was superior to 67.0% (75/112) in the western medication group (P < 0.05). For the patients collected from the meridian cosmetology group, as compared with that before treatment, E2 level was decreased (P < 0.01) and PRGE level was increased (P < 0.05).

CONCLUSIONThe meridian cosmetology achieves the superior efficacy as compared with the western medication group for the chloasma and it can regulate the levels of E2 and PRGE.

BACKGROUNDEmergence agitation is a common problem in pediatric anesthesia, especially after sevoflurane induction and maintenance anesthesia. The purpose of this study was to investigate the effect of sufentanil to reduce emergence agitation after sevoflurane anesthesia in children undergoing adenotonsillectomy compared with fentanyl.

METHODSOne hundred and five children, aged 3 - 11 years, were randomly allocated to receive normal saline (control group), sufentanil 0.2 µg/kg (S2) or fentanyl 2 µg/kg (F2) 1 minute after loss of the eyelash reflex. Anesthesia was induced and maintained with sevoflurane. Time to tracheal extubation, recovery time, Paediatric Anesthesia Emergence Delirium (PAED) scale, and emergence behavior were assessed.

RESULTSThe incidence of severe agitation was significantly lower in S2 and F2 groups vs. the control group, 4/32 and 15/34 vs. 24/34 respectively, (P = 0.002, 0.009, respectively). PAED scales were significantly different among three groups (P = 0.007), and lower in the S2 and F2 groups than in the control group (P = 0.007 and P = 0.025, respectively). And the incidence of severe agitation and the PAED scale score was significantly different between the S2 and F2 groups (P = 0.007, P = 0.019, respectively). Time to tracheal extubation and recovery time were similar in all three groups.

CONCLUSIONSAdministration of sufentanil at 0.2 µg/kg after induction of anesthesia reduced emergence agitation in children receiving sevoflurane anesthesia for adenotonsillectomy compared with fentanyl. This was without delaying the recovery time or causing significant hypotension.

OBJECTIVETo investigate safe range of acetabular prosthesis angle and the optimum combination of cup and neck in the range of activities of daily living (ADL).

METHODSA three-dimensional generic parametric and kinematic simulation module of THA was developed. Range of motion (ROM) of flexion > or = 110 degrees, internal-rotation > or = 30 degrees at 90 degrees flexion, extension > or = 30 degrees and external rotation > or = 40 degrees were defined as the normal criteria for desired ROM for activities of daily living (ADL), and ROM of flexion > or = 120 degrees, internal-rotation > or = 45 degrees at 90 degrees flexion, extension > or = 30 degrees and external rotation > or = 40 degrees as the severe criteria. The range of the changes in the general head-neck ratios (GR), the femoral neck anteversion (FA), the operative anteversion (OA) and operative inclination (OI) of the cup component were 2-2.92, 0 degrees-30 degrees, 0 degrees-70 degrees, 10 degrees-60 degrees respectively. For the collodiaphyseal angle (CCD) of 135 degrees, the corresponding OA related to the OI which every 5 degrees was calculated, and described using dots and lines in a coordinate system in which OI of acetabular cup was the horizontal ordinate and OA of acetabular cup was the vertical ordinate. All data was analyzed by SAS 6.12 software.

RESULTSLarge GR greatly increased the size of safe range and it was recommended that GR be more than 2.37 when the CCD-angle was 135 degrees as it further increases the size of safezone. The size of cup safety range of the severe criteria was smaller than normal criteria. When the CCD-angle was 135 degrees, the optimum relationship between OA of acetabular and FA of the normal criteria and the severe criteria can be estimated by the formula: Y1=-0.816X1 + 39.76 (R2=0.993), Y2=-0.873X2 + 47.04 (R2=0.999) respectively.

CONCLUSIONLarge GR greatly increases the size of safe-zone and it is recommended that GR be more than 2.37, so it extends the acceptable range of error that clinicians cannot avoid it completely. The larger range of the hip motion, the smaller size of the cup safe-zone,but can retrieve by increase the GR. The OA is negative with FA.

OBJECTIVETo investigate the serologic type, phage-biotype and toxic factor of Vibrio cholerae isolated from different sea products, analyze the relation between the Vibrio cholerae in sea products and cholera epidemiology, and provide references for forecasting cholera epidemic situation and drawing out a preventing plan.

METHODThe biotype of strains isolated was analyzed by using type and phage-biotype serological methods. The toxic gene was detected by PCR.

RESULTSThe constituent ratio of V. cholerae O139, Ogawa and Inaba were, respectively, 48.44%, 20.31% and 31.25% in 64 strains of V. cholerae. The result of phage-biotype showed that the 26 strains of V. cholerae O1 were all non-epidemic strains. The result of toxic gene detecting showed that positive rate of V. cholerae O139 was higher than those of Ogawa and Inaba.

CONCLUSIONThe positive rate of toxic gene in V. cholerae O139 was high and the V. cholerae O139 was mainly in turtle, breed aquatics water and crustacean, so these sea products were the important sectors in cholera prevention and control.
