Objective: To determine the relationship between serum omentin-1 concentration and bone mineral desity in postmenopausal women, and the adipose influence of tissue on bone mineral density (BMD). Methods: BMD values of 336 participants were measured by dual-energy-x-ray absorptiometry (DEXA) at various skeletal sites: the anteroposterior spine, femeral neck, total hip (T-hip) and total body BMD (TBMD). Body compositions including lean tissue mass (LTM) and body fat mass (FBM) were measured by DEXA. hTe plasma concentrations of adipocytokines (omentin-1, adiponectin,leptin,resistin,visfatin, andapelin) were measured by ELISA. Results: hTe overweight and obese groups had higher T-hip,femerol neck, intertrochanter BMDthan the nomal weight group. Plasma omentin-1 was negatively correlated with anteroposterior spine, femeral neck, trochanter, intertrochanter, T-hip and Ward’s BMD, after adjustment for age, BMI and fat body mass, and the correlation was not significant. Multiple stepwise regression anlysis revealed that lean body mass, menopause duration and estrogen level were the most important variables affecting the BMD and each explained 12.2%–13.7%, 6.9%–13.1%, 0.9%–1.7% of the variance. Serum adiponectin was independently associated with T-hip, lumbar spine and total BMD. Conclusion: Plasma omentin-1 is not significantly correlated with BMD in postmenopausal women. Lean body mass, menopause duration and estrogen level are the most important variables affecting the BMD. Serum adiponectin is an independent predictor of T-hip, lumbar spine and total BMD.

Objective To randomly compare the therapeutic effect and safety between Levetiracetam (LEV) and Phenobarbital (PB) in the treatment of neonatal seizures.Methods A total of 61 infants with acute convulsion were randomly divided into 2 groups:LEV group (n =30) and PB group (n =31) during January 2013 to December 2014 in Urumqi Children's Hospital.All neonates received routine management including etiology treatment and adverse drug reaction monitoring.In the LEV group,subjects received oral formulation of LEV with initial loading dose 30 mg/kg,followed by 15 mg/kg twice a day.If the seizures were not controlled completely,PB treatment was added until seizures were completed controlled.If seizures were controlled quickly,the dose of PB was gradually reduced and LEV was used as monotherapy.The subjects in PB group received intramuscular or intravenous injection of PB with 10 mg/kg as the first dose,then 5 mg/(kg · d) oral PB was administered,if seizures were not controlled,LEV treatment was added,then dose of PB was gradually reduced until seizures were controlled completely,and then patients were switched to LEV monotherapy gradually.The drug adverse reactions were observed.Results (1) After LEV or PB monotherapy,66.7％ (20/30 cases) and 54.8％ (17/31 cases) of the subjects obtained sustainable seizure free respectively.Although,there was a higher control ratio in LEV group,but no significant difference was observed between the 2 groups (P ＞0.05).(2) LEV group (16/30 cases,53.33％) had higher rapid seizure control ratio with seizure controlled within 24 h after first dosage administration than that of PB group (8/31 cases,25.80％),and there was significant difference (x2 =4.841,P =0.028).Further more,if adding the cases who had to change to use another comparative one (LEV or PB) due to their seizures failure control with the first one treated,LEV group (21/44 cases,47.72％) still had higher rapid seizure control ratio in total patients than that of PB group(10/41 cases,24.39％),and there was significant difference (x2 =4.988,P =0.026).(3) Eight cases who changed to LEV after PB as the first treatment drug failed obtained sustainable seizure free.(4) One case in PB group with transient urinary retention was observed but the symptom disappeared 36 h after PB withdrawal,and no significant drug adverse reaction was observed in LEV group.Conclusion LEV is more rapid and safe for seizure control of neonates than PB.

Objective:To observe the thermesthesia thresholds of the heat-sensitive acupoints in patients with knee osteoarthritis (KOA), and to provide scientific evidence for acupoint selection based on acupoint sensitization. Methods:Forty-six patients with KOA of swelling type were recruited. By using the quantitative thermesthesia testing, the thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance at Xuehai (SP 10), Neixiyan (EX-LE 4) and Yinlingquan (SP 9) were detected. The subjects were then divided into heat-sensitive groups and non-heat-sensitive groups according to whether there was a phenomenon of heat-sensitive moxibustion sensation at each acupoint, to compare the thermesthesia thresholds between the two groups. Results: The thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance were respectively (38.21±2.03)℃ , (44.4,±1.8,)℃ and (48.,9±0.,4)℃ in the heat-sensitive group of Xuehai (SP 10), versus (3,.,,±1.93)℃ , (42.91±2.0,)℃ and (4,.9,±1.14)℃ in the non-heat-sensitive group of Xuehai (SP 10); the thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance were respectively (3,.4,±1.,,)℃ , (44.,,±1.,3) , and (4,.48±0.4,) in the heat℃℃-sensitive group of Neixiyan (EX-LE 4), versus (3,.92±1.,9)℃ , (42.,2±1.94)℃ and (4,.,3±0.41)℃ in the non-heat-sensitive group of Neixiyan (EX-LE 4); the thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance were respectively (3,.30±2.23)℃ , (44.39±1.92)℃ and (4,.,,±0.,8)℃ in the heat-sensitive group of Yinlingquan (SP 9), versus (3,.0,±1.8,)℃ , (42.,3±1.88)℃ and (4,.91±0.,2)℃ in the non-heat-sensitive group of Yinlingquan (SP 9). The statistical analyses showed that the thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance of each heat-sensitive group (all the three acupoints) were significantly higher than those of each corresponding non-heat-sensitive group (P<0.01). Conclusion:There were differences in the thermesthesia thresholds between heat-sensitized and non-heat-sensitized acupoints in patients with KOA of swelling type; and the thermal sensation threshold, thermal pain threshold, and threshold of thermal pain tolerance of the heat-sensitized points were significantly higher than those of the non-heat-sensitized ones.

Objective To study the efficacy of hyperbaric oxygen(HO)for the delayed encephalopathy after acute carbon monoxide poisoning(DEACMP)Method One hundred and eleven patients who were diagnozed as the DEACMP from November 2000 to March 2007 in Tangdu Hospital the Fourth Military Medical University were randomly divided into two groups.Thirty-six cases were treated by onventional approach(group A),and 76 cases by HO besides conventional treatment(group B).The efficacy of HO was evaluated after 4courses of treatment. The curative effects were evaluated as(1)cured:clinical symptoms and signs fully disappeared,abnormal electroencephalogram recovered,patients were completely self-help and competent enough for routine work.(2)improved:chnical symptoms and signs partly disappeared,abnormal electroencephalogram partly recovered,patients were partial self-help and incompetent enough for routine work.(3)inefficacy:patient's condition didn't changed.Data were expressed as((x)±s)and analyzed with the chi-quare test and t-test.The statistical significance was established as P＜0.05.Results In group B,62(81.58%)were in good recover,9(11.84%)improved and 5(6.94%)were inefficacy;while in group A:21(58.33%)were in good recover,5(13.89%)were improved and 10(27.78%)were inefficacy.The effciency rate in group B was significantly higher(93.42%)than that(72.22%)in group A(P＜0.05),and the required time for the therapeutic effect noticed time in group B were significantly shorter(P＜0.05)Conclusions HO Can improve the therapeutic effects on DEACMP

Objective To investigate the efficacy and safety of Levertiracetam (LEV) in treating the neonates with intractable seizure, those who had under gone failed Phenobarbital (PB) treatment previously switched to or added LEV treatment currently.Methods Totally 14 neonates,designed as intractable seizure by clinical data and video electroencephalography(VEEG) and failed to PB treatment were enrolled in the study, and all neonates were switched to LEV or LEV + PB treatment.The initial loading dose of LEV was 30 mg/kg, followed by 15 mg/kg twice a day if symptoms were controlled 8-12 h,if not, followed by 30 mg/kg once.All neonates were switched to LEV monotherapy after the symptoms were controlled 48-72 h,if the symptoms could not be controlled by combined therapy of PB and LEV after 72 h, other therapies were administered.Electrocardiogram breath synchronous monitoring was performed during the first 72 h treatment.VEEG was performed during 1-3 months follow-up.Results (1) The symptoms of 8 (57.14％) out of 14 cases were completely controlled,2 neonates(14.29％) reduced seizure more than 50％ ,4 neonates(28.57％) failed to LEV or LEV + PB treatment,as a result,all of those neonates were switched to other treatments.(2) No drug adverse effect was observed.(3) One neonate died of hypoxic-ischemic encephalopathy combined with multiple organ failure during follow-up period, 7 cases were seizure-free with normal VEEG, 5 cases were switched to or added other antiepileptic drugs because of uncontrolled symptoms, and one neonate discontinued the follow-ups.Conclusions The high efficiency and safety of LEV for the treatment of the newborn seizures were proved by small samples of patients.And currently there is no evidence to prove PB might increase neuronal excessive apoptosis of the brain and the cognitive impairment, and more clinical researches are needed to promote LEV as a gleam of rescue medications of neonatal seizure as soon as possible.

Aim To investigate the role of miR-125 b and its DNA methylation in homocysteine ( Hcy )-in-duced vascular smooth muscle cells( VSMCs) prolifera-tion. Methods VSMCs were stimulated with 0,50, 100, 200, 500 μmol · L-1 Hcy respectively. Then qRT-PCR was used to detect the mRNA levels of miR-125b,and nested-touchdown methylation-specific PCR ( ntMS-PCR) was used to detect the methylation levels of miR-125b. VSMCs were transfected with miR-125b precursor or the inhibitor of miR-125b ,then 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyl tetrazolium bromide ( MTT ) assay was used to reflect the proliferation of VSMCs. The distribution of CpG islands of miR-125b promoter region was analyzed by bioinformatics meth-ods. VSMCs were stimulated with 100 μmol·L-1 Hcy and transfected with or without DNA methylation inhib-itors 5-nitrogen impurity cytidine ( AZC) , then the ex-pression of miR-125b was detected by qRT-PCR. Re-sults The mRNA levels of miR-125 b were decreased in 100,200,500 μmol·L-1 Hcy group compared with 0 μmol·L-1 Hcy group. The precursor of miR-125b could inhibit the proliferation activity and the inhibitor of miR-125 b could increase the proliferation activity of VSMCs cells. Bioinformatics analysis indicated that MiR-125 b promoter region had a CpG island whose length was 792 bp ( 1881-2672 ) . The miR-125 b pro-moter region methylation levels increased after Hcy in-tervention ( P <0. 01 ) . The expression level of miR-125 b increased after AZC intervention ( P <0. 05 ) . Conclusions ① Hcy promotes vascular smooth mus-cle cell proliferation maybe by down-regulating the ex-pression of miR-125b. ② Hcy down-regulates the ex-pression of miR-125 maybe by up-regulating the methy-lation levels of miR-125b promoter region.

Objective: To analyze the association between different sleep behaviors and overweight and obesity of junior high school students in Yangzhou City, and to provide a basis for policies and interventions related to adolescent health management. Methods: A total of 1 589 students in grades 7-9 from two middle schools in Yangzhou City were selected using the cluster sampling method and were administered with sleep time, bedtime, social jetlag difference, and sleep habits. Results: Totally 64.38% were sleep deprived during the school days, 86.78% went to bed too late, 46.51% had a social jetlag of ≥1 h, and 37.44% took a nap every day(Incluldes holidays and school days). Social jetlag length was statistically different between grades( F =6.97, P < 0.01 ). Girls[(0.95±0.65)h] shown significantly higher social jetlag than the boys[(0.76±0.59)h]( t=6.19, P <0.01). Later bedtime on weekends, later wake up time on weekends and poor sleep behavior were risk factors for overweight and obesity in junior high school students( OR=1.20, 1.14, 1.04, P <0.05). Conclusion Junior high school students had less sleep and later bedtimes with the increase of grade, and weekend bedtimes,wake up times and poor sleep behavior were independently associated with the risk of overweight and obesity in junior high school students. Parents and schools should be instructed to pay attention to their sleep health and carry out adolescent sleep health guidance.

Objective: To explore the effects of grandparent involvement in parenting on health related behaviors among urban preschool children, so as to provide a basis for the development of interventions for unhealthy behaviors among preschool children with different parenting pattern. Methods: A total of 5 431 preschool children aged 3-6 years old in Xinbei District, Changzhou City, were selected by census method during January to October, 2022. General household characteristics and health related behaviors of children were investigated by questionnaires, and the differences in health related behaviors with different parenting pattern involving grandparents were explored by the χ 2 test. A multifactorial Logistic regression model was used to analyze the effects of grandparenting on preschool children s health behaviors. Results: About 51.2% of preschoolers were raised by both parents, 46.1 % were co parented by grandparents, and 2.7% were raised by grandparents. After multifactorial Logistic regression analysis controlling for age, gender, annual household income, and family structure, children co parented by grandparents had a reduced risk of screen exposure time>1 h/d ( OR =0.79, P <0.05), with increased risks of outdoor activity time<2 h/d ( OR =1.30, P < 0.05 ), sleep duration <10 h/d ( OR =1.31, P <0.05), sleep difficulties ( OR =1.39, P <0.05) and adverse eating behaviors ( OR =1.20， P < 0.05), compared with children parented by both parents. Children raised by grandparents were at increased risk for outdoor activity time<2 h/d ( OR =2.19) and unhealthy eating behaviors ( OR =1.39) ( P <0.05). Conclusions Compared with children raised by both parents, the incidence of unhealthy behaviors is increased in children raised by parents and grandparents and in children raised by full grandparents. Active intervention should be focused on unhealthy behaviors of preschool children with pareting involving grandparents to promote the physical and mental health of preschool children.
