OBJECTIVE: To investigate the result of child-type micro-sensitive mattress sleep monitor on obstructive sleep apnea-hypopnea syndrome in children. METHOD: The PSG and child-type micro-sensitive mattress sleep monitor were synchronously performed on 58 cases of children with OSAHS. The breathing and sleep metrics were compared. RESULT: By PSG monitoring, 41 cases were diagnosed as mild OSAHS, 14 cases were moderate and 3 cases were severe. The results of mattress system monitoring showed mild OSAHS in 37 cases, 16 cases of moderate and severe OSAHS in 5 cases. Seven patients diagnosed as mild OSAHS monitored by PSG were classified as moderate by mattress system monitoring; three cases diagnosed as mild OSAHS by mattress system monitoring system were diagnosed as moderate by PSG. Among 14 cases of children diagnosed as moderate by PSG, three cases were diagnosed as mild by mattress system monitor and two cases as severe. Children diagnosed as severe by PSG got the same result by mattress system monitor. Two kinds of sleep monitoring methods were compared and there were no statistically significant difference in AHI (t = 2.316, P > 0.05), deep and shallow sleep constituent ratio (t = 2.280, t = 2.388, PF > 0.05). while there was significant difference in REM period Sleep constituent ratio (t = 3.135, P < 0.01). CONCLUSION Child-type micro-sensitive mattress is in good agreement with the PSG for diagnosing OSAHS in children, which can be used as a monitoring method in clinical work.

Objective To investigate the distribution of five indicators of hepatitis B(HBV-M)and its relationship with liver function parameters and HBV-DNA load in patients with chronic HBV infection in different stages.Methods The serum samples were collected from 456 patients infected with HBV.The HBV-M,liver functional parameters and HBV-DNA level were quantita-tively detected.According to the stages of disease,the patients were divided into 3 groups including chronic hepatitis B group(inclu-ding mild subgroup,moderate subgroup and severe subgroup),liver cirrhosis group(including compensatory subgroup,decompen-sated subgroup)and hepatocellular carcinoma goup.Results The ratio of HBsAg,HBeAg,HBcAb positive pattern(135 pattern) and HBsAg,HBeAb,HBcAb positive pattern(145 pattern)in the three groups were statistically different(P <0.05).In each chron-ic hepatitis B subgroup,both ALT and AST levels of 135 pattern were significantly higher than the other two patterns(P <0.05). In each liver cirrhosis subgroup and hepatocellular carcinoma group,there were statistically significant differences in ALB and TBIL levels between the three patterns(P <0.05 ).In each group,the HBV-DNA level of 135 positive pattern were significantly higher than the other two patterns(P <0.05).Conclusion With the advancement of chronic hepatitis B,there is a downtrend in the ratio of 135 pattern and increasing trend in the ratio of 145 pattern.If the stage of hepatitis B is discriminated,ALT,AST,ALB TBIL and HBV-DNA level were closely related to HBV-M pattern.

Objective To observe the effects of acetyl-l-carnitine (ALC) on autophagy, apoptosis and motor function after acute spinal cord injury (ASCI) in rats. Methods Thirty-six adult female Sprague-Dawley rats were randomly divided into sham operation group (Sham group, n=12), simple spinal cord injury group (SCI group, n=12), ALC treatment group (ALC group, n=12). Spinal cord injury model at the level of T10 segment was established using Allen's method. They were assessed with Basso-Beattle-Bresnahan (BBB) scale three days after injury. Then the rats were sacrificed, and the expression of microtubule associated protein 1 light chain 3 (LC3)-II in spinal cord was detect-ed with Western blotting and immunofluorescent labeling, and the number of apoptotic cells were assessed with TUNEL staining. Results The expression of LC3-II and the number of apoptotic cells increased in SCI group compared with those in Sham group (P<0.01), while the BBB score decreased (P<0.001). The expression of LC3-II increased and the number of apoptotic cells decreased in ALC group compared with those in SCI group (P<0.001), while the BBB score increased (P<0.01). Conclusion ALC may promote autophagy, and inhibit apopto-sis to improve the locomotor function after ASCI.

[ ABSTRACT] AIM:To illustrate the effect of methylene blue ( MB) on T-lymphocyte subsets and oxidative stress of the thymus in rats with paraquat ( PQ) poisoning.METHODS: Male SD rats ( n=40) were randomly assigned to 4 groups:normal group, control group, low-dose (2 mg? kg-1? d-1 ) MB group and high-dose (4 mg? kg-1? d-1 ) MB group.After 72 h, the pathological morphological changes of the thymus were observed under microscope with HE staining. The SOD activity and MDA content were measured by colorimetry method.The expression of Bcl-2, Bax, CD4 and CD8 was determined by immunohistochemical method.RESULTS:In MB group, the thymus tissue showed good corticomedul-lary demarcation.MDA content decreased and SOD activity increased, indicating that the ability of antioxidation enhanced. Bcl-2 and Bax expression was down-regulated, Bcl-2/Bax ratio increased, and CD4 positive cells increased.CONCLU-SION:MB protects against oxidative damage induced by PQ, and regulates the distribution of T-lymphocyte subsets in the cortex and medulla, thus relieving the persistent body damage.

[ ABSTRACT] AIM:In this study, we aim to obtain the induced pluripotent stem cells ( iPSCs) from the patients with sporadic Alzheimer disease ( AD) .METHODS:Three typical Alzheimer’ s patients were chosen, and the epithelial cells were isolated from their urine.We reprogrammed these cells into induced pluripotent stem cells by transfection of 4 factors (Oct4, Sox2, Klf4 and SV40LT) with the technique of electro-transfection.After getting these iPSCs, we continue to differentiate them into neural cells by a specific method—dual inhibition of Smad signaling.RESULTS: The primary cells from 3 AD patients were successfully reprogrammed to iPSCs, and these patients-derived iPSCs were differentiated into neural cells.There was no significant difference, during iPSCs reprogramming and neural differentiation, between cells from AD patients and normal people.CONCLUSION: The urine cells from AD patients were able to transfer to iPSCs, functional neurons and neurogliocytes.

Objective To investigate thyroid hormone nuclear receptor expression in peripheral blood mononuclear cells (PBMCs) and its relation with injury severity in patients with severe multiple trauma.Methods Twenty-eight patients with severe muhiple trauma and another 26 healthy subjects as control were enrolled in the study.At 2 days after injury,the levels of free triiodothyronine (FT3),free thyroxine (FT4) and thyroid-stimulating hormone (TSH) in peripheral venous blood were determined by using immunoradiometry,and the expressions of mRNA of the thyroid nuclear receptors (TRα and TRβ) in PBMCs were measured by using real-time RT-PCR.Results FT3 concentration in peripheral venous blood was significantly decreased in patients with severe multiple trauma versus healthy subjects.Concurrently,the expressions of TR mRNA (TRα and TRβ) were significantly decreased in PBMCs of patients with severe multiple trauma compared with healthy subjects (TRα mRNA:3.86 ±0.54 vs.5.24 ± 1.17,P ＜0.05;TRβ mRNA:9.86±2.27 vs.13.57 ±2.45,P ＜0.05).Pearson correlation analysis showed that FT3 concentration and the expression of TRβ mRNA correlated negatively with injury severity score (ISS) in patients with severe multiple trauma (r=-0.445,-0.496,P=0.018,0.007).Conclusions These data provide the evidence of a lowered activity of the thyroid signaling pathway in PBMC and a significantly negative correlation between FT3 concentration and the expression of TRβ mRNA in respect of injury severity in patients with severe multiple trauma.Additional investigations are needed to further determine the roles of the thyroid signaling pathway in adverse outcomes in the wake of severe multiple trauma.

Objective To evaluate the efficacy of metformin(MTF) in treatment of clomiphene (CC)-resistant patients with polycystic ovary syndrome (PCOS).Methods The published articles of randomized controlled trial (RCT) of comparison of MTF combined with CC and CC alone in treatment of CC-resistant PCOS were searched in PubMed,EMBASE,OVID,EBSCO databases and Cochrane Library,and these studies were screened under inclusion and exclusion criteria.The quality of included studies and extract data of comparison of ovulation rates and pregnancy rates were evaluated.And the Meta-analysis using statistic software RevMan 5.0 was completed.ResultTotal of 333 patients in total 8 trials were included.Meta analysis showed that MTF plus CC led to a significantly higher clinical ovulation rate ( OR =7.31,95 ％ CI:2.57 - 20.76,P ＜ 0.05 ) and pregnancy rate ( OR =7.93,95 ％ CI:2.45 - 25.63,P ＜ 0.05 ) than that of CC alone.Conclusion MTF can increase ovulation and pregnancy rates of CC-resistant PCOS women.

ObjectiveTo investigate the expression of Twist protein in adenocarcinoma of prostate and clinicopathological features and explore its roles in the carcinogenesis and progression of adenocarcinoma of prostate and its relationship with prognosis.MethodsThe expression of Twist was detected in 70 cases with adenocarcinoma of prostate and 30 cases with side cancer tissue by immunohistochemistry (EnlivionTM).ResultsThe expression of Twist protein in adenocarcinoma of prostate was higher than side cancer tissue.The expression of twist was related to Gleason grade,clinical stage and bony metastasis (P＜0.05),but it was not related to the age (P＞0.05).The survival rate of Twist protein positive patients was significant lower than negative patients(x2=9.52,P＜0.01).ConclusionsTwist might be an important biological marker for malignant transformation and invasion and metastasis adenocarcinoma of prostate,and the up-regulation of the expression of Twist reflects more invasion and poor prognosis.
