BACKGROUND:Emerging evidence shows that rs6756667 SNP EPAS1-A alele is beneficial for, however, the GG genotype is detrimental for adaptation to high-altitude hypoxia in Tibetan populations.
OBJECTIVE:To compare the EPAS1 gene rs6756667 polymorphism between Tibetan elite endurance athletes and Tibetan non-physical education major students and analyze its relationship to aerobic exercise capacity.
METHODS:Forty Tibetan athletes in Ganzi Tibetan middle and long distance athletes sports teams (athlete group) and forty Tibetan non-physical education major students in Ganzi (student group) were included in this study. The EPAS1 gene rs6756667 polymorphic loci were determined using PCR high-resolution melting analysis. The genetic polymorphism data from this study were compared withthe data from previous studies. Increase values of bone mineral density in the pelvis, upper and lower limbs were determined by dual-energy X-ray absorptiometry.
RESULTS AND CONCLUSION:There were significant differences in the genotype frequencies of EPAS1 rs6756667 AA, AG and GG between student group(50%, 47.5%, 2.5%)and athlete group(72.5%, 27.5%, 0;P< 0.05). The genotype frequency of GG was significantly increased in student group compared with athlete group (P< 0.05). There were differences in the frequencies of A alele and G alele between both groups (95%CI:0.459-0.908,P=0.011).Bone mineral density inthe pelvis, upper and lower limbs and whole body was significantly higher in student group than athlete group (P< 0.05). These findings suggest that EPAS1 gene rs6756667 polymorphism is related to aerobic capacity of Tibetan elite endurance athletes. rs6756667 SNP EPAS1-A alele is beneficial for, however, the GG genotype is detrimental for adaptation to high-altitude hypoxia in Tibetan athletes.

MicroRNA(miRNA) is a class of non-coding RNA that plays an important role in gene expression and controlling. In recent years,the role of miRNA in the development of the disease has aroused great interest. Abnormal osteoclastogenesis and persistent inflammatory response induced by wear particles or osteoblast differentiation and maturation is the main cause of aseptic loosening in joint replacements. New researches shows that persistent inflammatory response, osteoclastogenesis and osteoblast differentiation are closely associated with miRNA, suggesting that there are certain relations between miRNA and aseptic loosening of prostheses. Additionally, the alteration of the expression levels of some miRNA may be curative for aseptic loosening. With the findings of the new miRNA targets, the important role of miRNA is further confirmed.

Chronic kidney disease (CKD) is a serious chronic disease with high incidence, poor prognosis, and a variety of complications. Indoxyl-sulfate (IS) and p-cresol sulfate (PCS) are two typical gut-derived uremic toxins, which are produced by the co-metabolism of intestinal microbes and the host. With the progression of CKD, gut-derived uremic toxins such as IS and PCS accumulate in patients with CKD and thereafter accelerate the progression of CKD. Gut microbiota is closely related with CKD, and targeting gut microbiota to regulate gut-derived uremic toxins synthesis and metabolic pathways may be a promising strategy to delay the progression of CKD. In this paper, the relationship between gut microbiota, gut-derived uremic toxins, and CKD was analyzed, and the strategy to delay the progression of CKD by targeting gut microbiota and uremic toxins metabolism pathway was proposed.

Objective To investigate the current situation of the prevention and contml of iodine deficiency disorders(IDD)in Hubei Province,SO as to provide a policy.making basis for controlling work of IDD. Methods Using the method of proportional population sampling(PPS),30 eounties were seiected in Hubei Province.In each selected county,1 primary school was chosen.In every primary school,40 pupil8 aged 8～10 years were selected to examine thyroid size,intelligent quotient(IQ),and salt iodine contents at their home.In the selected pupils,2 boys and 2 girls were chosen to determine their urinary iodine contents in each age grouD.Twenty pupils in the above school and 5 housewives ileal"to this school were tested in health education questionnaire. Results The median of salt iodine was 30.1 mg/kg,and the rate of comsuming qualified iodized salt was 96.2% (1154/1200).The rates ofchild goiter were 6.5%(78/1200)by palpation and 4.1%(49/1200)by B ultrasound.The median of urinary iodine Was 358.4μg/L and mean of the IQ was 105.3±14.4.The rate of qualified scores of both students and housewives Was 25.5%(153/600)、90.7%(136/150).Conclusions The current Bituation of iedine nutrition is good.The goal of eliminating IDD has been achieved in Hubei Province.

Hepatic encephalopathy is a common metabolic neuropsychiatric syndrome in the development of end-stage liver disease. Since the concept of intestinal-liver-brain axis was proposed, the relationship between the pathogenesis of hepatic encephalopathy and the gut microbiota has been a hot research topic. In recent years, studies have confirmed that gut microbiota is involved in and affects various pathological processes of hepatic encephalopathy. This article combines the latest research progress at home and abroad to elaborate on the research status of regulating gut microbiota and thus interfering with the pathological process of hepatic encephalopathy, hoping to provide new ideas and methods for the intervention of hepatic encephalopathy based on the regulation of gut microbiota.

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.

ObjectiveTo observe the 2-8 years' follow-up results of percutaneous laser disc decompression(PLDD) on cervical spondylotic radiculopathy,and to identify factors affecting the outcome of PLDD.MethodsEighty-seven patients with cervical spondylotic radiculopathy were treated consecutively by PLDD in our hospital from December 2002 to June 2009,who were followed up for 2-8 years.There were 32males and 26 females,with the mean age of 51.8 years (range,26-74).The results were evaluated according to the Japanese Orthopedic Association's score of cervical spondylotic radiculopathy(JOA 20 score) and numeric rating scales (NRS) after surgery.Two years after the operation,the excellent and good rate of JOA score of patients with different genders,ages and duration of each subgroup will be compared.ResultsThe excellent and good rate were 37.9％,51.7％,65.5％,81.0％,82.8％,80.9％,72.4％ and 72.7％ at 1,3,6months and 1,2,4,6,8 years after operation respectively.Significant difference was found between the time points of 6 months to eight years after operation and that of one month after operation.The NRS score of the pain symptoms at the final follow-up was significantly reduced(P＜0.05).The excellent and good rate of patients whose course of disease (93.3％) was less than 18 months was significantly higher than that of those whose course of disease was over than 18 months(71.4％) two years after operation (P＜0.05).Conclusion The intermediate-term curative effect of PLDD for the treatment of cervical spondylotic radiculopathy is reliable and stable,and the postoperative curative effect may be influenced by patients' duration of disease.
