Objective To investigate the relationships between the neck circumference and cardiovascular risk factors of middle-aged and elder people in a community. Methods Altogether 9 665 community residents ( age≥40 years) were enrolled in the present study. The height, weight, neck circumference, waist circumference, blood pressure, total cholesterol, triglycerides, low density lipoprotein-cholesterol ( LDL-C ) , high density lipoprotein-cholesterol ( HDL-C) , blood glucose, glycosylated hemoglobin, and fasting insulin were measured, and documented in the questionnaire along with other basic information. After adjusted for age, Pearson correlation coefficient was used to analyze the relationship between the neck circumference and the binary variables of cardiovascular risk factors. SPSS16.0softwarewasusedforstatisticalanalysis. Results (1)Theneckcircumferenceswere(37.11±2.79)cm in male and (32. 79 ± 2. 31) cm in female;which were higher in males than females. In both males and females, after adjusted for age, the neck circumference was positively correlated to waist circumference, body mass index, blood pressure, plasma glucose, LDL-C, triglycerides, and insulin resistance, the neck circumference was negatively correlated to HDL-C(all P<0. 05);The neck circumference of males was positively correlated to total cholesterol(P<0. 01);The neck circumference of females was not correlated with total cholesterol(P>0. 05). (2) After adjusted for body mass index and the waist circumference, the neck circumference of males increased with the risk of diabetes ( OR=1. 14, 95% CI 1. 02-1. 28);while the higher neck circumference of females increased the risk of hypertension (OR=1.17,95% CI1.08-1.27),diabetes(OR=1.24,95% CI1.13-1.37),dyslipidemia(OR=1.17,95%CI 1.09-1.27),andinsulinresistance(OR=1.15,95% CI1.06-1.26). Theneckcircumferenceexertedhigher impact on women than it did on men. Conclusion The neck circumference is associated with the cardiovascular risk factors. This association in females is stronger than that in males. The neck circumference seems to be an independent indicator for the cardiovascular risk.

Objective To investigate the association between the neck circumference and central obesity in the elderly.Methods The neck circumference(NC),height,weight,waist circumference (WC) and hip circumference(HC) of 2820 subjects aged over 60 years were detected from some communities in Nanchang.All subjects were divided into different groups,according to the two different obesity indicators of WC and BMI.The relationship between NC and obesity was analyzed.A multiple linear regression analysis was conducted using the Enter method.An R()C curve analysis was employed to judge the tangent point of NC in central obesity.Results The height,weight and BMI were reduced along with age (all P＜0.05),and the waist hip ratio(WHR) was increased along with age(P＜0.01) in the elderly.The NC was decreased along with age in males(P＜0.01),and the WC was increased along with age in females(Pt＜0.01).The NC was longer in males than in females [(36.5±3.0) cm vs.(32.6±2.4) cm,P＜0.01].The NC was increased along with body weight,WC and BMI in the elderly:with each 1 kg increase in body weight,the NC was increased by 0.079 cm in males and 0.139 cm in females;with each 1cm increase in WC,the NC increased by 0.073 cm in males and 0.040 cm in females;with each 1 kg/m2 increase in BMI,the NC increased by 0.121 cm in males and 0.065 cm in females;with 1 year increase in age,the NC was decreased by 0.033 cm in males(all P＜0.05).when obesity was diagnosed according to both BMI and NC,the NC was longer in the obesity group than in the control group,(P ＜ 0.01).The area under receiver operating characteristic(ROC) curve of NC for diagnosing central obesity showed that the area was 0.802 and 0.743 in males and females,and the optimal cut-off value of NC was 36.85 cm and 31.75 cm in males and females,respectively.Conclusions NC is increased along with the increases of body weight,WC and BMI in the elderly.NC is significantly associated with central obesity.NC is more predictive of the central obesity when the value ＞36.85 cm in males and ＞31.75 cm in females.

Objective To investigate the relationship of parity and other reproduction-associated factors with metabolic syndrome(MS) in middle-aged and elderly women in Nanchang community.Methods Female permanent residents over 40 years old were sampled for a routine examination and a questionnaire survey covering basic information,5 894 subjects were enrolled and identified as effective cases.MS was diagnosed according to the standard of China Diabetes Society in 2004.Factors including age,education,profession,marital status,parity,child-bearing history of macrosomia,breastfeeding,menarche age,and menopausal age were analyzed in order to find their relationship with MS.The univariate logistic analysis was followed by binary logistic regression analysis if P＜0.05,and OR value and confidence interval were calculated.Results Univariate logistic regression analysis showed that age,education,profession,parity,breastfeeding,and menopausal age were influencing factors of MS (all P ＜ 0.05).There was no correlation to marital status,miscarriage history,child-bearing history of macrosomia,menarche age with MS(all P＞0.05).Binary Logistic regression analysis showed that the risk of MS increased with age:OR =1.51 (95 ％ CI 0.98-2.32) during 50-59 years,OR =2.10 (95 ％ CI 1.34-3.30) during 60-69 years,and OR =2.63 (95 ％ CI 1.61-4.31) in cases aged over 70 years,as compared to the group aged 40-49 years.The risk in non-manual workers increased about 34 percent OR =1.33 (95 ％ CI 1.04-1.70),compared with manual workers.The risk of MS increased with parity,being OR =1.46 (95％ CI 1.14-1.88),OR =1.78 (95％ CI 1.30-2.43),and OR =1.84 (95％ CI 1.24-2.72),with 2,3,and 4 child-bearings respectively as compared to cases with only one childbearing.The risk of MS was reduced with advancing menopausal age being about 6 percent reduction with each increased year of menopausal age(OR =0.94,95％ CI 0.90-0.99).There was no difference between education,breastfeeding and MS(P＞005).Conclusion Multiple parity,earlier menopausal age,less manual work,and aging seem to be the risk factors of MS in women.

Objective To explore the efficacy of targeted care for sleep by analyzing polysomnography (PSG) of the different stages of night sleep in patients with depressive disorder. Methods 80 depressive patients met the recruited criteria from Feb 2015 to Feb 2016 were sample-randomly divided into research group with targeted care and controlled group with routine nurse by random number table. PSG of each case was analyzed and Hamilton Depression Scale (HAMD) and Self-Rating Depression Scale (SDS) were used to assess at baseline and endpoint during 4 weeks period. Results Total sleep time, sleep efficiency, N3 and rapid eyes movement ratio of PSG were (395.74 ± 29.31) min, (80.42±1.92)%, (19.11±2.29)%and (16.01±2.55)%in research group, (372.34±24.37) min, (72.61 ± 1.64)%, (13.61 ± 2.38)%and (13.87 ± 2.03)%in controlled group (t=2.892-13.361, P<0.05). SDS at 2nd week and 4th week were (45.28 ± 6.28) points and (32.62 ± 4.65) points in research group, (48.63±7.54) points and (36.32±4.34) points in controlled group (t=-4.12,-4.43, P<0.05). HAMD at 2nd week and 4th week were (15.92 ± 2.62) points, (9.94 ± 2.32) points in research group, (18.27 ± 3.41) points and (12.45 ± 2.21) points in controlled group (t=-3.51,-4.35, P<0.05). Conclusions Efficacy of targeted care for sleep in patients with depressive disorder is better and sooner, and the intervention is good for both sleep quality and mood level.

Objective To evaluate the efficacy and safety of the hyper-CVAD/MA regimen as an intensified treatment option for 28 T cell and aggressive/highly aggressive B cell NHL in Chinese patients. Methods Clinical data of 28 NHL patients treated with hyper-CVAD/MA regimen from Jan 2005 to Sep 2008 were retrospectively analyzed. Results 27 NHL patients were available for the efficacy analysis, with a response rate of 70.4 %. For the 13 B cell lymphoma cases, the response rate was 84.6 %. The main toxicity was Grade Ⅲ or Grade Ⅳ myelosuppression in all cases and 2 treatment related deaths. Conclusion Hyper-CVAD/MA regimen had a high response rate in T cell and aggressive /highly aggressive B cell NHL lymphoma, companied by significant toxicity when treating Chinese patients. Further clinical practices are needed to pick up a suitable dose which can balance efficacy and safety.

Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.

Objective To investigate the protective effects of vascular endothelial growth factor-165 (VEGF165) transfected the endothelial progenitor cells (EPCs) mediated by lentivirus on acute lung injury (ALI) in rats. Methods The mononuclear cells from the male Sprague-Dawley (SD) rats were isolated and cultured to get the EPCs for study. The lentivirus vector carrying the human VEGF165 gene was constructed. According to the random number table method, 90 male SD rats were divided into ALI model group, phosphate buffer solution (PBS) group, EPCs treatment group, none transfected EPCs treatment group and VEGF165 transfected EPCs treatment group, and the rats in each group were subdivided into 4, 12 and 48 hours subgroups, with 6 rats in each subgroup. The rat model of ALI was reproduced by intravenous injection of oleic acid (0.15 μL/g). Then each treatment group was given PBS, EPCs, none transfected EPCs and VEGF165 transfected EPCs respectively with the same volume of 0.2 mL. For the groups with cells, about 1×106cells were contained. Abdominal aortic blood and lung tissue were harvested at 4, 12 and 48 hours. Arterial blood gas analysis was performed. The lung wet/dry weight ratio (W/D) was calculated. The expressions of induced nitric oxide synthase (iNOS), endothelin-1 (ET-1) and VEGF165 were determined by enzyme-linked immunosorbent assay (ELISA). After dyed with hematoxylin-eosin (HE), the lung tissue pathology was observed and the lung injury score was performed. Results Compared with the ALI model group, the arterial partial pressure of oxygen (PaO2) in EPCs, none transfected EPCs and VEGF165 transfected EPCs treatment groups was significantly increased from 4 hours, and lung W/D, expressions of iNOS and ET-1 were significantly decreased, and VEGF165 expression was significantly increased. Compared with the EPCs treatment group, the increase in PaO2, the decrease in lung W/D and expressions of iNOS and ET-1, and the increase in VEGF165 expression in VEGF165 transfected EPCs treatment group were more significant [4 hours: PaO2(mmHg, 1 mmHg = 0.133 kPa) was 82.84±10.69 vs. 72.34±9.36, lung W/D ratio was 4.83±0.23 vs. 5.55±0.37, iNOS (ng/mg) was 8.77±1.10 vs. 14.84±1.34, ET-1 (ng/mg) was 103.41±5.66 vs. 153.08±5.12, VEGF165 (ng/mg) was 130.56±12.16 vs. 83.03±5.95; 12 hours: PaO2(mmHg) was 91.67±6.81 vs. 78.5±8.81, lung W/D ratio was 4.44±0.35 vs. 5.32±0.25, iNOS (ng/mg) was 7.23±0.24 vs. 14.04±1.18, ET-1 (ng/mg) was 91.98±3.52 vs. 125.99±7.55, VEGF165 (ng/mg) was 164.49±5.71 vs. 96.61±6.12]; individual parameters reached valley value or peak value at 48 hours [lung W/D ratio was 4.26±0.30 vs. 4.89±0.15, iNOS (ng/mg) was 5.79±0.85 vs. 12.72±1.10, ET-1 (ng/mg) was 74.53±7.10 vs. 108.33±5.84, VEGF165 (ng/mg) was 237.43±10.79 vs. 134.24±11.99, all P < 0.05]. Over time, lung tissue injury in each group was gradually increased, and the lung injury score was gradually increased. The lung injury score at 48 hours in the EPCs, none transfected EPCs and VEGF165 transfected EPCs treatment groups were lower than that in the ALI model group. Compared with the EPCs treatment group, the VEGF165 transfected EPCs treatment group had a lower score at 48 hours (8.50±1.05 vs. 10.50±1.05, P < 0.05). Conclusion The transplantation of EPCs which were transfected with VEGF165 mediated by lentivirus could obviously improve the oxygen pressure, reduce the lung water seepage, decrease the iNOS and ET-1 expressions in lung tissue, and had obvious protective effects on ALI.

OBJECTIVETo screen for carriers of SMN1 gene mutation, which underlies spinal muscular atrophy (SMA), in 4931 pregnant women from Liuzhou region of Guangxi, and to determine the carrier rate.

METHODSCombined denaturing high-performance liquid chromatography (DHPLC) and multiple PCR techniques were used to detect the copy number of SMN1 gene. The carrier frequency was calculated. The spouse of the carrier was also screened, and prenatal diagnosis was provided to the couples who were both positive.

RESULTSAmong the 4931 pregnant women, 61 were found to harbor only one copy of the SMN1 gene, which yielded a carrier rate of 1.2%. Subsequent testing has identified 1 fetus carrying homozygous deletions of the SMN1 gene.

CONCLUSIONThe carrier rate of SMA mutation in Liuzhou region is slightly lower than that of other regions of southern China. DHPLC can effectively screen the carriers of SMA mutation and provide a basis for genetic counseling and prenatal diagnosis.

Objective: To investigate the clinicopathological and radiological features of benign fibro-osseous lesion (BFOL). Methods: Sixty-five cases of craniofacial BFOL, eight cases of peripheral ossifying fibroma (POF) and one case of low-grade central osteosarcoma diagnosed at Sichuan Provincial People′s Hospital between January 2010 and March 2019 were collected. The clinicopathologic features, hematoxylin-eosin and immunohistochemical (IHC) staining and radiographic features were analyzed. MDM2 gene amplification was detected by FISH in difficult borderline cases. Results: This cohort of BFOLs included 50 cases of fibrous dysplasia (FD), 12 cases of ossifying fibroma (OF), and three cases of juvenile psammomatoid ossifying fibroma (JPOF). The average ages of patients with FD,OF and JPOF were 31.7, 39.2 and 26.0 years respectively. The male to female ratio was 1.0∶1.8.The average age of POF was 47.0 years, with male to female ratio of 1∶7. Patient of low-grade central osteosarcoma was a 48-year-old man. Twenty-seven cases of FD were located in the jaw, and 23 cases were in other craniofacial bones. Nine cases of OF were located in the jaw, and three cases were in the nasal cavity. Two cases of JPOF were in the nasal sinus, and one was in the jaw. All POF were located in the gingiva, and low-grade central osteosarcoma was located in the mandible. The imaging features of FD were luffa-like or ground-glass like signal shadows with poorly defined borders with expansion. OF had clear borders or sclerosing margins. Both JOF and low-grade central osteosarcoma were expansile intraosseously and with focally invasive nodular masses with ground-glass like signal shadows; and POF showed soft tissue mass with bone formation. Histological features of BFOLs showed mixed fibrous and irregular osteoid lesions. FD had no clear relationship with the host bone and no osteoblasts surrounded the bone trabeculae. Osteoblasts rimming was found in OF, and the boundaries of the host bone were clear. JPOF and low-grade central osteosarcoma infiltrated the host bone focally, and the latter showed mild cellular atypia. MDM2 amplification was detected in low-grade central osteosarcoma. Conclusions BFOLs are a group of fibro-osseous lesions with similar morphology in the head and neck and face, but their clinical features and prognosis are different; and their imaging and histological characteristics are also slightly different. Attentions should be given to the combination of clinical, imaging and pathologic features of BFOLs, especially the differential diagnosis between BFOLs and low-grade central osteosarcoma. Molecular detection could be used to assist the diagnosis in difficult cases.

Early weaned piglets suffer from oxidative stress and enteral infection, which usually results in gut microbial dysbiosis, serve diarrhea, and even death. Rice bran oil (RBO), a polyphenol-enriched by-product of rice processing, has been shown to have antioxidant and anti-inflammatory properties both in vivo and in vitro. Here, we ascertained the proper RBO supplementation level, and subsequently determined its effects on lipopolysaccharide (LPS)-induced intestinal dysfunction in weaned piglets. A total of 168 piglets were randomly allocated into four groups of seven replicates (42 piglets each group, (21±1) d of age, body weight (7.60±0.04) kg, and half males and half females) and were given basal diet (Ctrl) or basal diet supplemented with 0.01% (mass fraction) RBO (RBO1), 0.02% RBO (RBO2), or 0.03% RBO (RBO3) for 21 d. Then, seven piglets from the Ctrl and the RBO were treated with LPS (100 μg/kg body weight (BW)) as LPS group and RBO+LPS group, respectively. Meanwhile, seven piglets from the Ctrl were treated with the saline vehicle (Ctrl group). Four hours later, all treated piglets were sacrificed for taking samples of plasma, jejunum tissues, and feces. The results showed that 0.02% was the optimal dose of dietary RBO supplementation based on diarrhea, average daily gain, and average daily feed intake indices in early weaning piglets. Furthermore, RBO protected piglets against LPS-induced jejunal epithelium damage, which was indicated by the increases in villus height, villus height/crypt depth ratio, and Claudin-1 levels, as well as a decreased level of jejunal epithelium apoptosis. RBO also improved the antioxidant ability of LPS-challenged piglets, which was indicated by the elevated concentrations of catalase and superoxide dismutase, and increased total antioxidant capacity, as well as the decreased concentrations of diamine oxidase and malondialdehyde in plasma. Meanwhile, RBO improved the immune function of LPS-challenged weaned piglets, which was indicated by elevated immunoglobulin A (IgA), IgM, β‍‍-defensin-1, and lysozyme levels in the plasma. In addition, RBO supplementation improved the LPS challenge-induced dysbiosis of gut microbiota. Particularly, the indices of antioxidant capacity, intestinal damage, and immunity were significantly associated with the RBO-regulated gut microbiota. These findings suggested that 0.02% RBO is a suitable dose to protect against LPS-induced intestinal damage, oxidative stress, and jejunal microbiota dysbiosis in early weaned piglets.
