Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.

Objective To compare the sensitivity and specificity of Leptospira interrogans using loop-mediated isothermal amplification (LAMP) and real-time PCR technology, then looking for a rapid,sensitive and specific methods for the detection of Leptospira interrogans. MethodsIn accordance with lipL41 gene from Leptospira interrogans, primers for LAMP and real-time PCR were designed and used to detect Leptospira interrogans in cultured 15 reference strains of 15 serogroups in China, then compared the sensitivity and specificity of the two methods in the detection of Leptospira interrogans. ResultsThe LAMP reaction could be completed within 30 min, and whole process of it less than 60 min. The whole real-time PCR reaction could be finished at about 60 min. Both of them had the same detection sensitivity and specificity,the lower detection limits in the reactions was approximately 100 copies and there was no false positive occurred. ConclusionBoth LAMP and real-time PCR were time-saving and had the same sensitivity and specificity. But LAMP reaction could be done under a constant temperature conditions, and need not a special expensive equipment. Therefore, as a sensitive and specific method for quantifying Leptospira interrogans,the LAMP assay was more rapidly and convenient than conventional methods.

ObjectiveThe purpose of the study was to summarize the characteristics of cellular and humoral immunity in children with Kawasaki's disease (KD),and to explore the role of cellular and humoral immunity in the pathogenesis of KD.MethodsOne hundred and ninety-six subjects with KD were diagnosed and observed.The serum IgG,IgM,IgA and C3,C4 levels were detected by velocity scatter turbidimetry.The levels of T lymphocyte subsets,natural killer cells (NK cells),and B cells were analyzed by flow cytometry.Chi-square test,independent t-test and Spearman analysis were adopted to analyze data.ResultsOne hundred and seventy-two cases were diagnosed as typical KD,24 cases were incomplete KD,17 cases were refractory KD,179 cases responded to IVIG therapy,and 34 cases were CAL.The occurrence of coronary artery lesion (CAL) in the refractory KD group was 52.9％,which was evidently higher than those patients responding to IVIG therapy(14.0％,P＜0.05).In the group of KD,the level of CD19 absolute value(1165±556)/μl was higher than that in the control group(P＜0.05),the ratio of CD4/CD8 (2.19±0.77) was higher than that in the control group (P＜0.05),the levels of serum IgM ( 1.41 ±0.45) g/L,IgA (0.81 ±0.35) g/L,C3 ( 1.31 ±0.26) g/L were higher than those in the control group (P＜0.05),the levels of CD8 (671±308)/μl,NK (337±233)/μl absolute value were lower than those in thc control group (P＜0.05).In refractory KD subgroup,the levels of CD19 absolute value,serum IgM,C3 and the ratio of CD4/CD8 were higher than those in the subgroup responding to IVIG therapy(P＜0.05),while the levels of CD8,NK absolute value were lower than those in the latter(P＜0.05).In the CAL subgroup,the levels of CD19 absolute value,serum IgM,IgA and the ratio of CD4/CD8 were higher than those in the non-CAL subgroup (P＜0.05),while the levels of CD8,NK absolute value were lower than those in the latter(P＜0.05).The differences of all data between typical KD subgroup and incomplete KD subgroup were insignificant (P＞0.05).The severity grade of CAL was positively correlated with the ratio of CD4/CD8(P＜0.05).ConclusionThere are cellular immunity and humoral immunity disturbances in the acute stage of KD,while cellular immunity disturbances are more striking.Cellular immunity and humoral immunity are all involved in the pathogenesis of KD.The immunity dysfunction is more significant in refractory KD and CAL.The occurrence rate of CAL is high in refractory KD.The ratio of CD4/CD8 is relevant to the severity of vascular injury.

The study aims to develop a rapid, sensitive and specified method of liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) for simultaneous determination of amlodipine, benazepril and benazeprilat in human plasma using amlodipine-d4 and ubenimex as internal standards (ISs). Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the positive mode for mass spectrometric detection. Analytes and ISs were extracted from plasma by simple protein precipitation. The reconstituted samples were chromatographed on a C18 (100 mm x 4.6 mm, 5 microm) column with mixture of methanol-acetonitrile-5 mmol.L- ammonium acetate-formic acid (30 : 30 : 40 : 0.1) as mobile phase at a flow rate of 0.6 mL.min-1. The standard curves were demonstrated to be linear in the range of 0.02 to 6.00 ng.mL-1 for amlodipine, 0.2 to 1,500 ng.mL-1 for benazepril and benazeprilat with r2>0.99 for each analyte. The lower limit of quantitation was identifiable and reproducible at 0.02, 0.2 and 0.2 ng mL-1 for amlodipine, benazepril and benazeprilat, respectively. The intra-day and inter-day precision and accuracy results were within the acceptable limit across all concentrations. The plasma samples were stable after four freeze-thaw cycles and being stored for 93 days at -20 degrees C. The method was applied to a pharmacokinetic study of a fixed-dose combination of amlodipine and benazepril on Chinese healthy volunteers.

The influence of inner cell mass (ICM) and trophectoderm (TE) score on pregnancy outcomes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts: S-ICM B/TE B group (n=91), the single blastocyst transfer of ICM B and TE B; D-ICM B/TE B group (n=579), double blastocysts transfer of ICM B/TE B; D-ICM B/TE C group (n=35), double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group (n=36), double blastocysts transfer of TE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group (74.96% vs. 57.14%, 57.43% vs. 37.14%, and 48.62% vs. 25%, respectively, P<0.05 for all). Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group (74.96% vs. 50%, and 57.43% vs. 33.33%, both P<0.05). Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy (OR=3.05, CI 1.70-5.46, P<0.001), while the trophectoderm score was a better one for early abortion (OR=0.074, CI 0.03-0.19, P<0.001). Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group (46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P<0.05), but there was no significant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Single ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy outcomes.

Objective:To investigate the clinicopathological characteristics and prognosis of invasive micropapillary carcinoma (IMPC) of the breast. Methods:Data of 65 IMPC cases obtained from the Fourth Hospital of Hebei Medical University between Janu-ary 2009 and December 2011 were retrospectively analyzed. The expression of epithelial membrane antigen (EMA) was evaluated us-ing immunohistochemistry (IHC) to detect the micropapillary component in the tumor. The patients were divided into 4 groups based on the percentage of micropapillary component:≤10%, 11%-30%, 31%-50%, and>50%. Expressions of estrogen receptor (ER), pro-gesterone receptor (PR), and HER-2 were analyzed by IHC. Kaplan-Meier method, Log rank test, and multivariate Cox proportional hazard model were used to determine the factors affecting post-treatment survival. Results:Of the 65 cases, 12 were simple IMPC, 46 were IMPC with invasive ductal carcinoma, and 7 were other invasive carcinoma cases. The≤10%, 11%-30%, 31%-50%, and>50%micropapillary component groups comprised 7.69%(5/65), 44.62%(29/65), 26.15%(17/65), and 21.54%(14/65) of the total cases, re-spectively. Statistically significant differences were found in the four groups (P<0.01). IHC results showed that the positive rates of ER, PR, and HER-2 in the IMPC tissues were 76.92%(50/65), 67.69%(44/65), and 24.62%(16/65), respectively. Statistical differences ex-isted among the groups (P<0.05). Kaplan-Meier method indicated that positive rate of lymph node metastasis, the proportion of IMPC, vascular invasion, and the expression of ER, PR, and HER-2 significantly affect survival time of IMPC cases (P<0.05). Conclusion:Positive rate of nodal metastasis, the proportion of IMPC, vascular invasion, and the expression of ER, PR, and HER-2 are correlated with the prognosis of IMPC.

Objective To compare the clinical efficacy and safety of isotretinoin erythromycin gel, a gel containing isotretinoin (0.05%) and erythromycin (2%), versus adapalene gel in the treatment of mild to moderate acne vulgaris. Methods A multicenter, randomized, open, parallel-controlled clinical study was conducted. A total of 192 patients with mild to moderate (Grade Ⅰ -Ⅲ ) acne vulgaris were enrolled in this study according to the grading criteria for acne severity in guidelines for the treatment of acne in China. Efficacy analysis was carried out in 169 patients and safety analysis in 190 patients. The patients were classified into trial group (n = 86) and control group (n = 83 ) to be treated with isotretinoin erythromycin gel or adapalene gel once a night for 6 weeks. Patients were evaluated at the baseline, on week 2, 4 and 6 during the treatment for the count of comedones (both open and closed), inflammatory papules and pustules, severity of acne and local or general adverse effects. Results After the start of treatment, the response rate gradually increased and severity of acne decreased in both groups. On week 6, the total response rate was 51.16% in the trial group and 40.96% in the control group (P ＞ 0.05), while a greater reduction in the count of pustules and inflammatory lesions was observed on week 4 and 6 in the trial group with a lower severity grade of acne compared with the control group (P ＜ 0.05 or 0.01 ). Adverse reactions were similar in both groups and manifested as tolerable local irritation. Conclusions The efficacy of isotretinoin erythromycin gel is similar to that of adapalene gel in the treatment of mild to moderate acne vulgaris, however, isotretinoin erythromycin gel seems superior to adapalene gel in reducing inflammatory lesions and rapidly improving severity of acne vulgaris.
