OBJECTIVETo assess the efficacy and safety of Xifeng Zhidong Tablet (XZT) in treating tic disorder children patients of internal disturbance of Gan-wind with phlegm syndrome (IDGWPS).

METHODSA stratified randomized, double-blinded, parallel control of placebo, multi-center trial was conducted in 160 subjects from 5 hospitals in China. They were randomly assigned to 2 groups, the test group and the control group, 80 in each group. Those in the test group were treated with XZT, while those in the control group were treated with placebos. The therapeutic course was 4 weeks for all. The effectiveness indicators covered main indicators and secondary indicators. Yale global tic severity scale (YGTSS) was taken as the main indicators. The amelioration of social function impairment, efficacy, single index of Chinese medical syndromes, Chinese medical syndrome efficacy as well as disappearance rate of single Chinese medical symptoms were evaluated as secondary indicators. The safety indicators included clinical adverse events, vital signs, blood/urine/stool routines, renal and liver functions, and electrocardiogram (ECG).

RESULTSAs for main indicators, the score of YGTSS decreased from 22.10 +/- 6.38 to 11.34 +/- 6.58 in the test group, while it decreased from 22.65 +/- 6.70 to 16.82 +/- 6.53 in the control group, showing statistical difference when compared with the same group before treatment (P < 0.01). Besides, the decrement was more significant in the test group after treatment (P < 0.05). As for secondary indicators, the total effective rate was 83.54% in the test group and 34.18% in the controlled group, showing statistical difference between the two groups (P < 0.05). As for social function impairment, 20,38, 16, 3, 1 case(s) in the test group were ranked as normal, minimal, mild, moderate, obvious degree, while 1, 24, 45, 7, and 0 case(s) in the control group were ranked as normal, minimal, mild, moderate, obvious degree. Better effect was obtained in the test group (P < 0.05).As for Chinese medical syndrome efficacy, it was 87.34% in the test group and 64.56% in the control group (P < 0.05). As for single index of Chinese medical syndromes, the disappearance rate of motor tics, irritability, dreaminess, abnormal tongue proper,abnormal tongue fur, and abnormal tongue pulse condition was 78.67%, 34.72%, 62.26%, 34.62%, 58.97%, and 39.74%, respectively in the test group, while they were 34.67%, 13.11%, 21.82%, 15.58%, 25.97%, and 19.48%, respectively in the control group. Better results were shown in the test group (P < 0.05). Totally 5 adverse events occurred. The incidence of adverse events was 3.75% in the test group and 2.53% in the control group.

CONCLUSIONSAfter 4 weeks of XZT treatment, the integral of YGTSS could be obviously reduced, the degree of social function impairment ameliorated, and Chinese medical syndromes improved. In addition, no adverse reaction occurred in this study.

BACKGROUNDIn the past several decades we have seen multiple advances in the reconstruction for girls born with vaginal agenesis. This study aimed to evaluate the technical feasibility, anatomical and functional outcomes of one-stage laparoscopic and gasless laparoscopic vaginoplasty with sigmoid colon for the patients of vaginal agenesis (Mayer-Rokitansky-Kuster-Hauser syndrome).

METHODSWe did a retrospective review of a total of 150 women with Mayer-Rokitansky-Kuster-Hauser syndrome treated at Beijing Anzhen Hospital, Capital Medical University from March 2006 to August 2010. The patients were divided into the CO2 pneumoperitoneum laparoscopic group and the abdominal wall lift of gasless laparoscopic group. Sigmoid colon vaginoplasty approaches were performed in all of the patients. The surgical techniques, perioperative results, complications, anatomical and functional outcomes of vaginoplasty were recorded.

RESULTSAll procedures were performed successfully. Significant differences in the operative time and intraoperative blood loss existed in the laparoscopic vaginoplasty group compared with the gasless laparoscopic vaginoplasty group. The patients who underwent sigmoid colon vaginoplasty had good cosmetic results without the problem of excessive mucus production. The postoperative complications were minimal. During a mean follow-up of 15.6 months, no stenosis or shrinkage was encountered. The subjective sexual satisfaction rate with the surgical outcomes in all patients was 83.3%.

CONCLUSIONSLaparoscopic or gasless laparoscopic vaginoplasty with sigmoid colon are effective and feasible approaches for women with congenital vaginal agenesis. The procedures have satisfactory anatomical and functional results.

Objective To investigate the image changes of proton magnetic resonance spectroscopy (1H-MRS) in children with epilepsy and their clinical significance. Methods Sixty-four patients with epilepsy,admitted to our hospital from March 2008 to March 2011,and 10 healthy children as control group were chosen in our study; the patients were divided into MR normal group and MR abnormal group according to the results of MR imaging. All of them received 1H-MRS examination on the hippocampal area.The ratio of NAA/Cho+Cr was compared between each 2 groups. Results No significant differences on the ratio of NAA/Cho+Cr were noted between the fight and left sides in all the groups (P＞0.05).The ratio of NAA/Cho+Cr was significantly different:MR normal group and control group enjoyed obvious difference as compared with MR abnormal group (P＜0.05); however,MR normal group and MR abnormal group existed no statistically significant differences (P＞0.05). Conclusion 1H-MRS is more sensitivity than MRI in children with epilepsy,therefore,1H-MRS can find the lesions earlier than MR imaging.

OBJECTIVETo investigate the mechanism of the acupoint sticking therapy with Chuanfuling for preventing and treating asthma.

METHODSThirty male SD rats were randomly divided into a control group (normal saline, p.i. +no acupoint sticking+ normal saline, spray inhalation), model group (normal saline with ovalbumin, p.i. +no acupoint sticking+ normal saline with ovalbumin, spray inhalation), and acupoint sticking group (normal saline with ovalbumin, p.i. +acupoint sticking with Chuan fuling+normal saline with ovalbumin, spray inhalation), 10 rats in each group. The incubation period of nodding breath, symptom of asthmatic attack, expression level of interleukin-4 mRNA (IL-4 mRNA) and interferon-gamma mRNA (IF-gamma mRNA), as well as pathological changes on the middle leaf of right lung, were observed in each group.

RESULTS(1) Comparing with the control group, the model group was showed that the expression level of IL-4 mRNA in the peripheral blood cells (PBMC) was increased, while hyperemia, edema and eosinocyte (EOS) invasion of lung tissue was more serious (P < 0.01). (2) Comparing with the model group, the acupoint sticking group was showed that the expression level of IL-4 mRNA in PBMC was decreased, the incubation period of nodding breath was prolonged for induced asthma on the fifth and seventh time with lower frequency, while in the lung tissue EOS invasion was reduced (P < 0.05), but there were no significant changes on the hyperemia and edema (P > 0.05).

CONCLUSIONAcupoint sticking for treating asthma of model rats with Chuanfuling can inhibit the expression level of IL-4 mRNA in PBMC, and the release of the inflammatory mediator and cytokine from the EOS to the air passage, in order to reduce the injury of epithelial layer and high reaction on the air passage.

OBJECTIVETo investigate the correlation between blood flow assessed by CT perfusion imaging and characteristics of microvascular ultrastructure in non-small cell lung cancer (NSCLC).

METHODStwenty-eight patients with non-small cell lung cancer proven surgically and pathologically underwent perfusion CT examination. The patients were divided into a hyper-perfusion group and a hypo-perfusion group by the median value of blood flow, and then the differences of microvascular ultrastructure in the two groups were analyzed.

RESULTSThe median BF value of the 28 patients was 36.40 ml×100 g(-1)×min(-1). Take this median value as the boundary, the group with hypo-perfusion showed a significantly lower BF value than the group with hyper-perfusion [(30.84 ± 4.79) ml×100 g(-1)×min(-1) vs. (49.67 ± 10.89) ml×100 g(-1)×min(-1), t = -5.925, P < 0.001]. The group with lymph node metastasis showed a significantly lower BF value than the group without lymph node metastasis [(30.78 ± 5.24) ml×100 g(-1)×min(-1) vs. (50.73 ± 11.16) ml×100 g(-1)×min(-1), t = 3.490, P = 0.015]. The maturity of microvessels of the hyper-perfusion group was higher than that of the hypo-perfusion group. Under the electron microscope, the microvessels in the hypo-perfusion group showed a more narrow lumen, poorer integrity of basement membrane, a more close relationship between cancer cells and microvascular wall, and cancer cells were more easily seen in the microvascular lumen.

CONCLUSIONThe blood flow value of CT perfusion imaging may be related with the abnormal microvascular ultrastructure, and may be helpful to the prediction of metastasis risk in NSCLC.

Objective: To explore the relevant gene, signaling pathway for permanent atrial fibrillation (pAF) occurrence in order to provide the molecular basis of the pathogenesis of pAF. Methods: Our research included in 2 groups: pAF group, n=7 patients and Control group, n=4 healthy subjects with sinus rhythm. Agilent 4x44K microarray was used to analyze the mRNA in left atrium for differential gene expression profile. Based on Gene Ontology, KEGG and Biocarta databases, differentially expressed genes were studied for their relevant function and signaling pathway. Furthermore, the genes with significant differences were verified by quantitative real time PCR (qRT-PCR) in pathological specimen from 5 pAF patients and 5 normal heart donors. Results: The expression profile identified 987 abnormally expressed genes, 567 of them were down-regulated and 420 were up-regulated. 9 genes with significant differences were verified by qRT-PCR in pathological specimen and the changes were similar to microarray; those genes were closely related to pAF by involving left atrium fibrosis, electrical remodeling, inflammation, cellular stress response, metabolism and transcription regulation. GO and Pathway analysis indicated that down-regulated genes were mainly involved in metabolic processes; up-regulated genes had the effects on cellular stress response, immune response and platelet activation. Conclusion: Microarray technology identified some important genes related to pAF occurrence; such genes involved in left atrial structural and functional remodeling via affecting cellular metabolism, inflammation, immune response and thrombogenesis in relevant patients.
