AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.

We studied the epidemiological characteristics of human bocavirus 4 (HBoV4) in children with a- cute gastroenteritis in Lanzhou (China). A total of 331 stool specimens were collected from children aged < 5 years with acute diarrhea at the First Hospital of Lanzhou University between July 2012 and June 2013. Specimens of HBoV were identified by nested polymerase chain reaction assays. Compared with related sequences in GenBank, the HBoV-positive strain isolated in the present study was,quite surprisingly, a rare genotype named HBoV4. This strain was a typical HBoV4,with high levels of nucleotide and amino acid homology to the Thailand strain, JQ267789 (98.9% and 98.7%, respectively), and the USA strain, GQ506568 (97.6% and 97.4%, respectively). This is the first report of HBoV4 as the causative agent for acute gastroenteritis in pediatric patients in China. This strain is one of two genotypes of HBoV that are currently circulating.

This study aimed to amplify major genome segments (VP7, VP4, VP6, VP2 and NSP2-5) of porcine G3 group A rotavirus (GARV) LLZ212 isolated in our laboratory, determine their genotypes, and explore the evolutionary relationships between G3 GARV strains isolated from humans and pigs in Lulong County, Hebei Province, China. Major genome segments of seven GARV strains were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the segments were sequenced. The genome segments of seven GARV strains were determined by the online RotaC genotyping tool (RotaC v2.0). The reference sequences of each GARV genome segment were downloaded from GenBank. Homology and phylogenetic evolutionary analyses were conducted using the MEGA 5.0 and DNAStar software packages. LLZ212 isolated from pigs in Lulong had the following genotype: G3-P[8]-I5-C1-N1-T1-E1-H1. All human GARV strains had the following genotype: G3-P[8]-I1-C1-N1-T1-E1-H1. The VP7, VP4, NSP4 and NSP5 genes of the LLZ212 strain had the highest nucleotide identities with the human GARV E885, CMH014/07, Wa and RMC321 strains, respectively, and these clustered together in a sublineage. The VP6, NSP4 and NSP5 genes of the LLZ212 strain shared the highest nucleotide identities with the porcine GARV PRG921 strain, while VP2 associated most closely with porcine GARV OSU strain, and these also clustered in a sublineage. A rare porcine G3-P[8]-I5-C1-N1-T1-E1-H1 GARV strain was identified, which may represent a reassortment between porcine and human viruses. In conclusion, the VP7, VP4, NSP4 and NSP5 genes of LLZ212 share high levels of sequence identity with human GARV, while VP2, VP6, NSP2 and NSP3 cluster with porcine GARV.

Objective To investigate the effect of selenium on proliferation and apoptosis of chondrocytes of articular cartilage cultured in vitro in Kaschin-Beck disease(KBD) patients and normal person, to explore the role of selenium in control of KBD, and to provide evidence for selenium's effect on the growth of normal cartilage cells. Methods The articular cartilage samples of grade Ⅱ and Ⅲ KBD patients were selected according to the national "Clinical Diagnosis of KBD" (GB 16003-1995). Chondrocytes of 5 KBD and 5 non-endemic normal accidentswere separated and cultured in vitro. KBD group and control group were given different doses of selenium (0,0.0125,0.0250,0.0500,0.1000,0.2500,0.5000,1.0000 mg/L, respectively). Methyl thiazolyl tetrazolium (MTT),flow cytometric analysis, and immunocytochemical staining were used to observe the effect of selenium on cell growth and apoptosis in KBD and normal persons. Results MTT results showed that the cell proliferation rate in each dosage group of the control group at the 6th day(0.086 ± 0.025,0.077 ± 0.012,0.073 ± 0.027,0.071 ± 0.017,0.058 ± 0.028,0.052 ± 0.028 and 0.046 ± 0.037) was significantly lower than that of 0 mg/L group(0.138 ± 0.026,all P < 0.05);the average cell proliferation rate was negative( - 0.001 ± 0.001, - 0.003 ± 0.000, - 0.003 ± 0.001and - 0.004 ± 0.001 ) in 0.1000 - 1.0000 mg/L dose group, which was significantly lower than that of the 0 mg/L group(0.025 ± 0.003, all P < 0.05);compared with 0 mg/L group(0. 115 ± 0.011), the KBD 0.2500 mg/L dose group promoted cell proliferation(0.128 ± 0.037, P < 0.05), the KBD 1.0000 mg/L dose group inhibited cell growth (0.071 ± 0.019, P < 0.05). The apoptotic rate of 0.0500 - 1.0000 mg/L dose control group [ (18.88 ± 0.02)%,(17.58 ± 0.01)%, (17.09 ± 0.04)%, (56.00 ± 0.02)%, (57.85 ± 0.03)% ] were higher than that of the 0 mg/L group[(13.51 ± 0.01)%, all P < 0.05];compared with 0 mg/L group[(25.84 ± 0.02)%], the apoptotic rate in KBD 0.0250 - 0.2500 mg/L dose group [ ( 13.69 ± 0.02) %, ( 15.96 ± 0.03 ) %, ( 16.68 ± 0.03 ) %, ( 16.67 ± 0.02) % ]were lower, and the apoptotic rate in 0.5000, 1.0000 mg/L dose group [ (59.58 ± 0.03)%, (73.48 ± 0.04)% ] were significantly higher(all P < 0.05). The Fas expression in KBD 0.0500 - 0.2500 mg/L dose groups[ (41.2 ± 1.5)%,(40.3 ± 2.0)%, (50.2 ± 2.5)%] were lower than those of the same dose control group with selenium intervention [(52.4 ± 1.0)%, (67.2 ± 4.0)%, (75.1 ± 5.0)%, all P < 0.05], the caspase-3 expression in KBD 0.0500,0.1000 mg/L dose groups[ (40.8 ± 1.1 )%, (45.1 ± 2.1 )%] were lower than those of the same dose control group with selenium intervention[ (68.0 ± 3.0)%, (70.6 ± 3.5)%, all P < 0.05 ]. Conclusions Appropriate dose of selenium supplementation (0.1000 - 0.2500 mg/L) could promote the growth of KBD chondrocyte, decrease cell apoptosis,but have a damage when the dose of selenium > 0.5000 mg/L;doses of selenium that could promote the growth of KBD chondrocyte does not mean to promote the growth of normal cartilage cells in vivo.

Abstract:This study aims to investigate the genetic characteristics of group A rotavirus (GARV) G9P[8] strains from infantile diarrhea samples in Hebei Lulong region from 2009 to 2011. We randomly selected five GARV G9P[8] strains in Hebei Lulong region from 2009 to 2011, amplified the 11 gene fragments of GARVs by RT-PCR, and analyz their full-genome sequences by homology and phylogenetic analysis with DNAStar and MEGA. The nucleotide homology between strains LL11131077 and LL11131083 in 2011 was significantly higher than hat etween them and the other three strains in 2009 and 2010. The G9P[8] GARVs circulating in Hebei Lulong region from 2009 to 2011 elenged to the same genotype as the prevalent G9P[8] GARVs in other parts of the world. However,the two strains in 2011, compared with those in 2009 and 2010, were located in a different sub-branch of the phylogenetic tree and had amino acid mutations at many sites.

This study aimed to study the epidemiological and clinical characteristics of human bocavirus 1-4 (HBoV1-4) in children with acute diarrhea in Lanzhou and to investigate the association between HBoV and acute gastroenteritis. A total of 331 stool samples were collected from children aged under 5 years with acute diarrhea at the Department of Pediatrics, the First Hospital, Lanzhou University, between July 2012 and June 2013. Nested PCR was used to screen for HBoV and a general PCR was employed to screen other common diarrhea viruses. We found human bocavirus 1, 2, 3 and 4 in 26, 15, 7 and 1 cases, respectively. There was no specific seasonal distribution of HBoV, with infections occurring throughout the year. HBoV was mostly found in children aged between 7 and 12 months, with a mean age of 11.04 months (+/- 6.92 months), and 93.88% of affected children were aged under 2 years. Overall, 71.3% of mixed infections were mixed and the majority of other infections were caused by rotavirus. There was no statistical difference in the incidence of fever and vomiting associated with HBoV infection. A rare virus strain, HBoV4 (LZFB086), was identified, which showed highest levels of nucleotide sequence identity (99.0%) with a single Thai HBoV strain (JQ267789). No case of HBoV2B was found. In conclusion, HBoV1 was a major etiological pathogen of HBoV in pediatric cases in Lanzhou. HBoV4 was detected in feces for the first time in China. The rate of mixed infections was high and rotavirus was dominant. The data presented suggests that HBoV is not a major causative agent of gastroenteritis.

Objective To investigated the effect of TangNaiKang (TNK) on VEGF protein expression of GK rats Thoracic aorta. Methods 51 male GK rats were divided into five groups randomly: model group, pioglitazone group, and TNK treatment group (low, immediate and high dose). Another 10 male Wistar rats were served as normal control group. GK rats were fed with high-grease forage, while normal control group was fed with a standard diet. Fasting blood glucose, general HE staining and VEGF protein expression were detected by immunohistochemistry. Results The fasting glucose had a significant decline in TNK treatment groups. HE staining showing TNK can ameliorate intima thickness, reduce hyperplasia of shallow vascular smooth muscle cell, and improve wavy and plexiform arrangement of elastic lamina. Immunohistochemistry also showed that TNK decreased VEGF protein expression of great vessels. Conclusion TangNaiKang can prevent and cure diabetic vascular complication of GK rats.
