Objective To observe the effect of different needling retaining times in clinical curative effect of acupuncture on the treatment of periarthritis humeroscapularis.Methods A total of 60 patients, who met the inclusion criteara, were randomly divided into 2 groups according to random number table method, 30 patients in each group. Both groups were treated with the same acupuncture therapy for 20 times, but the needling retaining times were different as 20 minutes and 40 minutes. The curative effect rates, Visual Analog Scale (VAS) and Constant-Murley Score (CMS) were evaluated.Results After the treatment, the VAS scoresin 40mins group was significantly lower than that in the 20 mins group (2.67 ± 1.03vs.3.60 ± 1.48,t=-3.251, P<0.01); the CMSin 40 mins group was significantly higher than the 20 mins group (73.20 ± 10.88vs.66.47 ± 12.62,t=-2.199,P<0.05). The curative effect rates of the 40 mins group was 26.7% (8/30), which was significantly higher than 3.3% (1/30) in the 20 mins group (χ2=4.706,P=0.030). The total effective rates in the 40 mins group was 90.0% (27/30), which was significantly higher than 96.7% (29/30) in the 20 mins group (χ2=0.268,P=0.605).Conclusions Acupuncture treatment for the patients with periarthritis humeroscapularis showed that the 40 minutes of needling retaining times had better symptom improvement and restore function effects than 20 minutes, however the total effective rate was no significant difference.

OBJECTIVETo identify the expression characteristics of the 1700001022RIK (RIKEN cDNA 1700001022) gene in mice and explore its function by bioinformatic analysis.

METHODSUsing the expression profile of gene microarray, we detected the expression of a new testis-specific gene, 1700001022RIK, in mice. We analyzed its expression characteristics in the testis tissue and their changes in different developmental stages of the testis by RT-PCR, real-time RT-PCR, Western blot, and immunohistochemistry. We performed bioinformatic analysis using a bioinformatic software.

RESULTSThe 1700001022RIK gene was specifically expressed in the mouse testis in an age-dependent manner, most highly in the adult mice. The 1700001022RIK protein was mainly expressed in the spermatogonia, spermatocytes, and round spermatids of the adult mice. Bioinformatic analysis showed that the 1700001022RIK protein amino acid sequence had a high similarity in human and mice, which indicated that this gene was highly conserved in mammals.

CONCLUSION1700001022RIK is a testis-specific gene mainly expressed in the spermatogonia, spermatocytes, and round spermatids of seminiferous tubules, which might be involved in the regulation of spermatogenesis.

OBJECTIVETo evaluate the soft profile and hard tissue changes after maxillary protraction with skeletal anchorage implant in treatment of Class III malocclusion during growth period.

METHODS18 patients with skeletal Class III malocclusion were treated with maxillary protraction for about 9 months, (3.5 +/- 0.1) N, with skeletal anchorage implant and face mask. Cephalometric records were analyzed to assess the changes of maxillo-facial structure of the hard and soft tissue before and after treatment.

RESULTSAll patients' Class III profiles were corrected. Maxillary growth increased, chin clockwise rotated, facial convexity angle increased, lower lip protrusion decreased. Facial vertical height ratio, nasolabial angle, upper lip protrusion and mentolabial sulcus changed unconspicuously. Upper incisors kept in sites, lower incisor upright, maxilla moved forwards. SNA, ANB significantly increased. SNB decreased and the mandible clockwise rotated.

CONCLUSIONThe maxilla is effectively protracted without significant rotation by using skeletal anchorage implant. The undesired effects of conventional protraction therapies, such as labial tilt of upper anterior teeth and extrusion of the maxillary molars, are reduced or eliminated with skeletal anchorage implant. These effects can conspicuously correct profiles of the patients with skeletal Class III malocclusion, make the profile more harmonious and aesthetic.

In this study, a 15-mer phage display peptide library was employed to pan against human rotavirus immobilized on solid phase. 4 different peptides were selected and could bind with rotavirus particles specifically. Plaque reduction neutralization test and MTT analysis results indicated that 3 of the peptides can inhibit rotavirus infecting in vitro. A peptide which sequence is QSNPIHIITNTRNHP showed the best efficiency--93% neutralization infectivity. Two other peptides, A and B, showed 40% and 50% neutralization infectivity respectively. Amino sequence analysis results indicate the 3 peptides containing 2 conserved motifs: SNPIHII and NIP. No putative trypsin hydrolysis site was found in C peptide, however, 4 and 3 potential sites were found in A and B peptides respectively. Using trypsin inhibitor, both A and B peptides showed the similar antiviral effect as that of C peptide. It suggests that the intactness of the 2 conserved motifs play an important role in counteracting virus infection. According to the results of this study, peptide C is hopeful to be exploited as an antiviral peptide drug.

Background/Aims: Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disease characterized by recurrent abdominal pain and bowel dysfunction. However, the majority of previous neuroimaging studies focus on brain structure and connections but seldom on the inter-hemispheric connectivity or structural asymmetry. This study uses multi-modal imaging to investigate the abnormal changes across the 2 cerebral hemispheres in patients with IBS. Methods: Structural MRI, resting-state functional MRI, and diffusion tensor imaging were acquired from 34 patients with IBS and 33 healthy controls. The voxel-mirrored homotopic connectivity, fractional anisotropy, fiber length, fiber number, and asymmetry index were calculated and assessed for group differences. In addition, we assessed their relevance for the severity of IBS. Results: Compared with healthy controls, the inter-hemispheric functional connectivity of patients with IBS showed higher levels in bilateral superior occipital gyrus, middle occipital gyrus, precuneus, posterior cingulate gyrus, and angular gyrus, but lower in supplementary motor area. The statistical results showed no significant difference in inter-hemispheric anatomical connections and structural asymmetry, however negative correlations between inter-hemispheric connectivity and the severity of IBS were found in some regions with significant difference. Conclusions The functional connections between cerebral hemispheres were more susceptible to IBS than anatomical connections, and brain structure is relatively stable. Besides, the brain areas affected by IBS were concentrated in default mode network and sensorimotor network.

OBJECTIVETo investigate the epidemiology of pediatric human immunodeficiency virus (HIV) infection in six provinces of China.

METHODSA cross-sectional study was conducted in six provinces with the highest HIV prevalence. Surveys on demographics and HIV-related questions (transmission modes, time of diagnosis, clinical stage, laboratory test) were distributed to clinicians in these provinces. Descriptive and bivariate analyses were performed on the completed surveys.

RESULTSSurvey results of 650 children [405 males and 245 females; average age: (7.9 +/- 3.2) years] were eligible for analysis. The interval between possible transmission and diagnosis was (7.1 +/- 3.2) years. The location distribution was as follows: 570 cases (87.7%) in Henan Province, 23 cases (3.5%) in Guangxi Province, 21 cases (3.2%) in Yunnan Province, 19 cases (2.9%) in Hubei Province, 10 cases (1.5%) in Anhui Province, and 7 cases (1.1%) in Shanxi Province. Transmission routes included mother-to-child transmission (75.1%), blood transfusion/ plasma donation (15.7 %), and injecting drug use (IDU, 0.5%). Former plasma donation (FPD) was the main transmission route in some provinces (Henan, Shanxi, Hubei, and Anhui), while IDU was the main transmission route in other provinces (Guangxi and Yunnan). The average age in the FPD provinces was significantly higher than that in IDU provinces [(8.1 +/- 3.2) vs. (5.4 +/- 2.2) years, P <0.001]. Among 178 patients in all six provinces who required treatment (on the basis of CD4 count or WHO staging), 133 (74.7%) did not receive treatment and 45 (25.3%) received antiretroviral therapy.

CONCLUSIONMother-to-child transmission is the main transmission mode in pediatric patients. Efforts should be made to strengthen the diagnosis and treatment of pediatric HIV/AIDS patients.

To observe the effect of geniposide on non-alcoholic fatty liver disease (NAFLD), and discuss the mechanism of geniposide for NAFLD from the aspect of free fatty acid, forty healthy Wistar male rats were randomly divided into normal group, model group, geniposide and Xuezhikang group. The rats in normal group were fed with normal diets, and the rats in other 3 groups were given with high-fat diet for 8 weeks to induce the NAFLD models. From the week 5 to end of week 8, the rats in geniposide and Xuezhikang group were intervened with corresponding medicines. The body weight, liver wet weight, and fat weight of the rats were recorded. Visual and pathological changes in hepatic tissues were observed with HE staining. The contents of TG, FFA, FAS, AMPK, ACCase and Malonyl-CoA in hepatic tissue, contents of CHO and LDL-C in serum and activities of AST and ALT in serum were detected by using corresponding methods. The results showed that the body weight, liver wet weight, and fat weight of the rats, CHO, LDL-C, ALT and AST levels in serum, TG, FFA, FAS, ACCase and Malonyl-CoA levels in hepatic tissues of the rats in model group were significantly higher than those in normal group (P<0.01), while AMPK activity was significantly lower than that of the normal group (P<0.01), with obvious visual and pathological steatosis in hepatic tissues, and inflammatory injury occurred in model group. Compared with the model group, body weight of the rat, fat weight, levels of FFA in hepatic tissues, ALT and AST activities in serum, liver wet weight, TG, FAS, ACCase and Malonyl-CoA levels were significantly decreased in geniposide group (P<0.01), while the AMPK activity in hepatic tissues was significantly increased (P<0.05),with improvement in visual and pathological performance. Compared with the model group, liver wet weight, fat weight, TG and FFA levels in hepatic tissues, and LDL-C level in serum were significantly decreased in Xuezhikang group (P<0.05). Compared with Xuezhikang group, the body weight of rat, fat weight and FFA level in hepatic tissues were significantly lower in geniposide group (P<0.01), but with no significant difference in other aspects. These findings indicated that geniposide was highly effective in improving the pharmacological effect of NAFLD induced by high-fat diet, and the mechanism was achieved through AMPK-ACCase-Malonyl-CoA-FFA axis.
