Objective To investigate the association of the polymorphism of rs3750344 and rs1435252 of G-protein family GABABR2 gene with obesity in population of Uygur and Han. Methods 785 Uygur subjects from Xinjiang and 425 Han subjects from Jinan Maternity and Child Care Hospital were recruited by epidemiology survey. Exposure indicators such as body mass index (BMI), total cholesterol (Tch), triglyceride (TG), fasting glucose (Glu) concentration were measured. Two single nucleotide polymorphisms (SNPs) of rs3750344 and rs1435252 of GABABR2 gene were typed with Taqman. Linkage disequilibrium and haplotype were analysed with Haploview software. Results The frequency of rs1435252 was significantly different in AA carries of Uygur subjects between overweight group (12.5%) and normal weight group (6.6%), the subject with AA genotype significantly increased risk of overweight (OR=1.43, 95% CI: 1.06~1.91). The frequency of rs1435252 was significantly different in A alleles carries of Han subjects between obesity group (80.0%) and normal weight group (65.2%), the subject with A alleles significantly increased risk of obesity (OR=2.13, 95%CI: 1.18~3.86). The C alleles of rs3750344 significantly decreased risk of obesity (OR=0.69, 95%CI: 0.49~0.97) in Uygur, but the significance disappeared after controlling for covariates of age and gender. Conclusion The rs1435252 A allele of GABABR2 gene is a risk factor for overweight or obesity in population of Uygur and Han.

Using a UPLC-MS/MS (MRM) and cocktail probe substrates method, the metabolic fingerprint of the compatibility of Radix Aconite (RA) and Radix Paeoniae Alba (RPA) and its effect on CYP450 enzymes were investigated. These main CYP isoforms include CYP 1A2, CYP 2C, CYP 2E1, CYP 2D and CYP 3A. Compared with the inhibition effect of RA decoctions on CYP450 isoforms, their co-decoctions of RA and RPA with different proportions can decrease RA' inhibition on CYP3A, CYP2D, CYP2C and CYP1A2, but can not reduce RA' effect on CYP2E1. The metabolic fingerprints of RA decoction and co-decoctions with different proportions of RPA in CYP450 of rat liver were analyzed by UPLC-MS. Compared with the metabolic fingerprints of RA decoction, the intensity of diester-diterpenoid aconitum alkaloids decreased significantly, while the intensity of monoester-diterpenoid alkaloids significantly increased in the metabolic fingerprints of co-decoctions of RA and RPA. The results suggest that RA coadministration with RPA increased the degradation of toxic alkaloid and show the effect of toxicity reducing and efficacy enhancing.

Objective To analyze the feasibility of body surface electrodes instead of multipair esophageal electrodes for the evaluation of neural respiratory drive in patients with COPD. Methods Diaphragm electromyo-gram(EMG)from body surface electrodes and multipair esophageal electrodes,was recorded in 29 patients with stable COPD recruited from outpatient clinic. Changes of neural respiratory drive of two kinds of electrodes during resting and maximal isocapnic ventilation (MIV) were observed before and after inhalation of bronchodilators. Results Ventilation significantly improved ,RMS-sur and RMS-eso significantly decreased after the inhalation of bronchodilators during resting and MIV. RMS-sur and RMS-eso were significantly correlated(r=0.660,P<0.01). Conclusion EMG from the surface electrodes may be a useful and noninvasive technique to evaluate neural respi-ratory drive in patients with COPD.

HK-2 cells were cultured with various concentrations of glucose and insulin for 12,24,48,72 h.Transforming growth factor-?_1(TGF-?_1) protein in supematant was measured by ELISA,while TGF-?_1 mRNA expression was assessed by RT-PCR.Data showed that high concentration of glucose and insulin up-regulated the expression of TGF-?_1 in HK-2 cells through different pathways.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.

Background and Objectives: Low-intensity pulsed ultrasound (LIPUS) promotes differentiation and regulates biological functions of various stem cells, but its effect on the endothelial differentiation of periodontal ligament stem cells (PDLSCs) is unclear. This study investigated the effect of LIPUS on endothelial differentiation and angiogenesis in PDLSCs and the role of the mechanically sensitive ion channel Piezo1 in this process. Methods: and Results: PDLSCs obtained from healthy people were used for endothelial induction, and 10 μg/ml lipopolysaccharide (LPS) was used to simulate the inflammatory state. The induced cells were treated with LIPUS (50 mW/cm2 , 1.5 MHz) to study its effect on the endothelial differentiation of PDLSCs and the tube formation of differentiated cells. PCR, flow cytometry, immunofluorescence, and Matrigel tube formation assays were used to detect the differentiation and tube formation of PDLSCs. GsMTx4 was used to inhibit the expression of Piezo1, and the role of the Piezo1 pathway in the endothelial differentiation and microvascular formation of PDLSCs after LIPUS treatment was studied. The data showed that LIPUS increased endothelial differentiation and angiogenesis in PDLSCs under inflammatory or noninflammatory conditions. The use of an inhibitor weakened the effect of LIPUS. Conclusions This study demonstrated that LIPUS can activate the expression of Piezo1 and promote the endothelial differentiation and microvascular formation of PDLSCs.

OBJECTIVETo observe the outcome of the fractured immature anterior permanent teeth after pulpotomy by X-ray measurement.

METHODSA total of 31 (25 cases) fractured immature anterior permanent teeth after pulpotomy was reviewed. Radiographic measurements were performed on 12 cases with unilateral fractured central incisors and completely formed roots after pulpotomy and 100 (50 subjects) healthy maxillary central incisors.

RESULTSThe roots development continued after pulpotomy, and the root length and periapical configuration were both similar to the healthy teeth, but some root canals became narrow or even nearly obturated at the root apex. There was no significant difference in root canal width between healthy right and left maxillary central incisors at the site of 1/4 [right: (0.67 +/- 0.14) mm, left: (0.66 +/- 0.12) mm, P > 0.05], 1/2 [right: (1.05 +/- 0.19) mm, left: (1.04 +/- 0.17) mm, P > 0.05], 3/4 [right: (1.78 +/- 0.34) mm, left: (1.76 +/- 0.30) mm, P > 0.05] of root, but the root canal width of the fractured incisors at the same site was significantly different from that of the contralateral healthy incisor, the 1/4 site pulpotomy: (0.70 +/- 0.23) mm, control: (0.99 +/- 0.17) mm, the 1/2 site pulpotomy: (1.16 +/- 0.24) mm, control: (1.51 +/- 0.25) mm; the 3/4 site pulpotomy: (1.96 +/- 0.34) mm, control: (2.24 +/- 0.36) mm.

CONCLUSIONSThere was a tendency that the root canals of fractured teeth after pulpotomy became narrowed and obturated. It should not be followed up for too long to perform root canal treatment when roots completely formed.

Background Implantation of phakic posterior chamber intraocular corrective lens(ICL)is a new choice for correction of high myopia.Different from laser assisted in situ keratomileusis,implantation of phakic posterior chamber ICL will allow the good imaging quality because it remaines the matched relationship between cornea and lens.But its visual quality after operation is concerned by patient and ophthalmologists.ObjectiveThis study was to observe the effectiveness of implantation of posterior chamber phakic ICL on visual quality in patients with high myopia.Methods Eighty-four high myopia eyes of 42 patients accepted implantation of posterior chamber phakic ICL and follow-up of 6-month duration.The visual acuity,refractive status,wavefront,contrast sensitivity and accommodation were examined and compared before and after surgery.This clinical study complied with Declaration of Helsinki.The written informed consent was obtained from each patient before operation.Results A prospective observational trial design was used.The uncorrected visual acuity and best corrected visual acuity after operation were better than preoperative ones in all of the patients.The eye numbers of ＞ 0.3 were increased after operation in comparison with before operation with a stable result among 1 day,1 month and 6 months after surgery (x2 =10.70,P＞0.05).Spherical equivalent refraction was(-15.38 ± 1.03)D before surgery and(+0.55 ±0.06)at 1 day,(-1.22±0.09)D at 1 month and(-0.68 ± 0.06)D after 6 months,showing a significant difference among them(F=16 559.90,P＜0.05).Total aberrations and higher-order aberrations were 11.00±0.25 and 0.43 ±0.05 before surgery,the wavefront aberrations were 2.21 ± 0.56 and 0.47±0.04 at 6 months after surgery with significant difference(t =1.65,P =0.10).Each spatial frequency contrast sensitivity and glare sensitivity on photopic and seotopie conditions in postoperation were higher compared with the preoperative(P＜0.05).The accommodation in 1 month and 6 months after surgery was greater than that of preoperative in the patients ＜-16 D(preoperation:2.75 ± 1.20 ; postoperation 1 month:5.75 ± 1.44,postoperation 6 months:6.00 ± 1.52)(P＜ 0.05),however,in the ＞-16 D group,no considerably change in accommodation was seen after surgery(F=1597.70,P＜0.05).No significant difference was found in accommodation between before and after surgery in ＞-16 D group(F=2.67,P＞0.05).Conclusions Visual quality of high myopia is obviously improved after implantation of posterior chamber phakic ICL,but its long-term outcome is need to further study.

Objective To explore the association between estimated glomerular filtration rate (eGFR) and metabolic syndrome (MS) . Method The data were from the China Health and Nutrition Survey (CHNS) . The data included the physical measurement and biochemical markers of adults of CHNS in 2009. Finally, 7309 individual observations were included in the analysis. Results According to the criteria of MS, 2034 patients were diagnosed as MS, and the prevalence was 27.83%. There were 1508 (74.14%) patients had moderate reduced eGFR in MS patients, and 3357 individuals (63.64%) were diagnosed as moderate reduced eGFR in non-MS patients. There was significant difference between two groups (X2=72.13, P<0.001) . The incident of moderate reduced eGFR was positively associated with fasting plasma glucose (OR=1.22, 95%CI: 1.06-1.42, P=0.005), triglyceride (OR=1.21, 95%CI: 1.05-1.38, P=0.005) and negatively associated with HDL-C (OR=1.23, 95% CI: 1.06-1.41, P=0.004) . Conclusion The MS and its components might be the influencing factors of developing moderate reduced eGFR, and the screening should be focused on the population with MS.
