ABSTRACT
Background Overweight/obesity in children are a global health issue. Preschool age is an important stage of children's growth and development and dietary behaviors, so it is crucial to explore dietary behavior characteristics and childhood overweight/obesity. Objective To explore the association between dietary behavior characteristics and overweight/obesity in preschool children in Shanghai, and the consistency of children's eating behavior characteristics with their parents'. Methods The children aged 3 to 6 years in 5 kindergartens in Shanghai in 2015 were selected by convenience sampling and surveyed. Their height and weight were measured. Children's and parents' dietary behavior characteristics were self-reported by their parents. According to the weight-for-height recommended by the World Health Organization, excess weight was calculated by the following formula: excess-weight%=[(measured weight - standard weight)/standard weight×100%]; obese is determined at excess-weight% > 20%, overweight: excess-weight% at 10%-20%, normal weight: excess-weight% at −10%-<10%. Chi-squared test and t test were used to compare the differences of demographic and dietary behavior characteristics between overweight/obese and normal weight children. Multiple logistic regression models were used to evaluate the association between dietary behaviors and overweight/obesity. The consistency of dietary behavior characteristics was tested between children and their parents. Results Among the 897 preschool children, 217 (24.2%) were overweight/obese and 680 (75.8%) were of normal weight. The birth weight [(3439±472) g vs. (3361±418) g] and proportion of monthly household income < 10000 yuan (17.1% vs. 10.7%) in the overweight/obese children were significantly higher than those in the normal weight children, and there were no statistical differences in sex, age, gestational age, time of adding complementary foods, outdoor activities after school every day, and parental BMI. After adjusting for potential confounders such as sex, age, household income, outdoor activities after school every day, and parental overweight/obesity, frequently having puffed food (OR=2.46, 95%CI: 1.20-4.95), western-style fast food (OR=3.52, 95%CI: 1.41-8.79), and carbonated drinks (OR=2.92, 95%CI: 1.37-6.13), often eating a lot (OR=1.51, 95%CI: 1.09-2.08) and having a good appetite (OR=2.60, 95%CI: 1.87-3.62), having regular meals (OR=1.48, 95%CI: 1.07-2.03), and fast eating (OR=3.37, 95%CI: 2.10-5.42) were positively associated with children's overweight/obesity (P<0.05). Children's partial/picky eating was inconsistent with fathers' behavior (P<0.05), while the other dietary behaviors were similar with both mothers' and fathers'. Conclusion Eating behavior characteristics of preschool children are associated with overweight/obesity, and affected by their parents. Early identifying dietary behavior problems and improving dietary habits of children might be an effective strategy in preventing and controlling the occurrence and development of obesity in childhood.
ABSTRACT
Objective@#To differentiate the inflow and outflow channels of gastric varices in cirrhotic portal hypertension patients using multi-slice spiral CT (MSCT), and to assess the relationship between calculable CT volume of gastric varices and the amount of tissue adhesive.@*Methods@#97 cases with cirrhotic gastric varices who were admitted from November 2013 to August 2017 were selected. The type and shape of gastric varices were observed before tissue glue injection treatment by MSCT. The correlation between CT volume of gastric varices and the amount of tissue adhesive was evaluated by Spearman rank correlation coefficient and Univariate linear regression analysis.@*Results@#MSCT showed that Le, g type had the highest proportion (54.6%), followed by Le, g, Lg (20.6%). Le, Lg and Lgf type accounted for 17.5%, and 5.2%, respectively, while Lgf+b accounted for 2.1%. On MSCT, varices of the gastric fundus were in the direction from bottom to top, and 75% of the fundus had a large curved side varices combined with gastric and renal shunt. Under the gastroscopy, varices in the small curved side of the gastric fundus from near to far were formless. In addition, varices in the large curved side of the gastric fundus when observed from different angles to the direction of blood flow (reverse gastroscope) were 72.7% (near and far) or 20.5 % (far and near). There was a positive correlation between CT volume (R = 0.97, P < 0.001) and the amount of tissue adhesive (Y1 = 0.35 + 0.65X1, Univariate linear regression equation; ρ = 0.89, P < 0.001, Spearman correlation analysis).@*Conclusion@#MSCT can recognize the vascular shape and inflow and outflow channels of gastric varices. A positive correlation between CT volume and the amount of tissue adhesive, suggested that the CT volume measurement before treatment could be used as one of the method to predict the amount of tissue adhesive.
ABSTRACT
Objective To study the relationship between the pain of the patients with lumbar intervertebral disc herniation (LIDH) and the changes of serum cytokine,and to discuss the clinical significance.Methods From January 2014 to December 2016,74 cases of LIDH diagnosed in the 323rd Hospital of the PLA were selected,including 45 males and 29 females,whose age was 46.2± 16.1 years,and the duration 22.6± 7.8 months.According to the VAS pain score,37 cases were mild,23 cases were moderate and 14 cases were severe.The control was 30 cases of healthy physical examination in the same period,18 males and 12 females,age 45.3 ± 15.8 years.All subjects were collected for venous blood on fasting.MDA,superoxide dismutase (SOD),interleukin-6 (IL-6),tumor necrosis factor (TNF),thromboxane (TX),endothelin (ET),prostaglandin E (PGE) and calcitonin (CA) were all measured by radioimmunoassay.The results were analyzed statistically.Results The compared with normal control group,serum cytokines MDA,SOD,IL-6,TNF,TX,ET,PGE and CA increased in different degrees (P＜0.05～0.01).The VAS assessment of severe pain in LIDH was significantly higher than that of mod erate or mild pain (P＜0.05～0.01).Logistic analysis showed that these serum cytokines were closely related to the pain of LIDH (OR=2.415～4.127,95％CI=1.146～11.735,P＜0.05).Conclusion The serum cytokines in patients with LIDH are closely related to the degree of pain,suggesting that these cytokines in serum may affect biochemical metabolism in the process of pain.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression of CHCHD2, a potential tumor marker, in tumor and adjacent tissues from patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Immunohistochemistry was used to detect the expression and location of CHCHD2 in the tumor tissues from 60 patients with NSCLC and 35 adjacent tissues to analyze the correlation of CHCHD2 expression with the clinicopathological variables and overall survival of the patients. The expression profile of CHCHD2 mRNA in NSCLC was analyzed using Oncomine database.</p><p><b>RESULTS</b>The positivity rate of CHCHD2 was significantly higher in the tumor tissues than in adjacent tissues in patients with NSCLC (75.0% vs 17.1%). CHCHD2 positivity in the tumor tissues was associated with lymph node metastasis, pathological TNM stage, and tumor grades but not with age, gender, or histological type of the tumors. Analysis using Oncomine database showed that CHCHD2 mRNA was expressed at significantly higher levels in NSCLC than in normal control group (P<0.05). Kaplan-Meier survival analysis showed that NSCLC patients with a positive expression of CHCHD2 had a significantly shorter overall survival time than those negative for CHCHD2 (P<0.05).</p><p><b>CONCLUSION</b>As a potential tumor marker, CHCHD2 over-expression plays a role in the occurrence and progression of NSCLC and promotes tumor invasion and metastasis, and can potentially serve as an indicator for early diagnosis and prognostic evaluation of NSCLC.</p>
ABSTRACT
AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ. METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared. RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05). CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effectiveness and safety of azithromycin in treatment of bronchial asthma.</p><p><b>METHODS</b>Reports of randomized controlled trials (RCTs) describing azithromycin for treatment of asthma published before December 2013 were searched in CNKI, WANFANG, PubMed and Medline databases. The data of the included RCTs were extracted and the data quality was evaluated by two assessors independently. Meta-analyses were performed with Revman 5.1 software.</p><p><b>RESULTS</b>Eight RCTs were identified. Meta-analysis of the data showed that compared with the control group, azithromycin treatment significantly improved the patients' PEF (WMD=0.15, 95%CI=0.06-0.24, P=0.001), scores of asthma control test (ACT) (WMD=1.59, 95%CI=0.95-2.23, P<0.00001), and FEV1% (WMD=1.44, 95%CI=0.40-2.49, P=0.007), but the improvement of FEV1% was observed only in Chinese patients (WMD=1.48, 95%CI=0.40-2.57, P=0.007). The scores of asthma control questionnaire (WMD=0.07, 95%CI=-0.11-0.25, P=0.45) or asthma quality of life questionnaire (WMD=-0.06, 95%CI=-0.42-0.31, P=0.77) were not affected by azithromycin. No severe adverse events were reported in these included studies.</p><p><b>CONCLUSION</b>Azithromycin for asthma treatment can improve PEF, ACT and FEV1% (in Chinese patients only) but shows no significant effect on the quality of life of the patients. Azithromycin is well tolerated and may therefore be beneficial as adjuvant therapy for asthma.</p>

<p><b>BACKGROUND</b>Sclerostin, expressed exclusively by osteocytes, is a negative regulator of bone formation. To gain insights into the action of sclerostin in postmenopausal osteoporosis, we evaluated serum sclerostin levels in postmenopausal women and investigated its possible associations with bone turnover markers in patients with postmenopausal osteoporosis.</p><p><b>METHODS</b>We detected serum sclerostin, and measured lumbar spine bone mineral density in 650 Chinese postmenopausal women. We also assessed serum levels of β-isomerized C-terminal crosslinking of type I collagen, intact N-terminal propeptide of type I collagen, N-mid fragment of osteocalcin, 25-hydroxyvitamin D, and estradiol.</p><p><b>RESULTS</b>Serum sclerostin levels were lower in postmenopausal osteoporotic women compared with non-osteoporotic postmenopausal women ((38.79 ± 7.43) vs. (52.86 ± 6.69) pmol/L, P < 0.001). Serum sclerostin was positively correlated with lumbar spine bone mineral density (r = 0.391, P < 0.001) and weakly negatively correlated with β-isomerized C-terminal crosslinking of type I collagen, intact N-terminal propeptide of type I collagen, N-mid fragment of osteocalcin (r = -0.225, P < 0.001; r = -0.091, P = 0.046; r = -0.108, P = 0.018; respectively) in postmenopausal osteoporosis. There was no significant association of serum sclerostin with age, body mass index, 25-hydroxyvitamin D, and estradiol (r = -0.004, P = 0.926; r = 0.067, P = 0.143; r = 0.063, P = 0.165; r = -0.045, P = 0.324; respectively).</p><p><b>CONCLUSION</b>Sclerostin may be involved in the pathogenesis of postmenopausal osteoporosis and may play a role in bone turnover.</p>

·AIM: To evaluate the efficacy and safety of intravitreal triamcinolone acetonide(TA) as treatment for macular edema associated with retinal vein occlusion(RVO).·METHODS: The study group consisting 30 patients (30 eyes) with RVO combined with macular edema received intravitreal 4mg TA. Changes in best-corrected visual acuity (BCVA), intraocular pressure(IOP), examination with slit-lamp microscope, fluorescein angiography and optical coherence tomography(OCT) were observed during the follow-up. Statistical analysis was conducted with SPSS 12.0 software.·RESULTS: The visual acuity(VA) of all patients was significantly improved and the central macular thickness (CMT) was significantly relieved. There was no correlation between course, age, CMT before injection and the type of RVO. There was positive correlation between visual acuity before injection and after injection.·CONCLUSION: Intravitreal injection of TA is an easy-operated and safe therapy. After injection, macular edema can be rapidly relieved. VA at baseline is the predictor for the prognosis of VA. Some patients experience recurrence of macular edema between 3 to 6 months after injection.
ABSTRACT
The process of injury and repair in airway epithelium involves cell spreading and migration followed by cell proliferation. IQ domain GTPase-activating protein 1 (IQGAP1) acts in a series of cell processes, but has not been clarified in lung epithelial cells. In this study, a widely used model of injury and repair in vitro by scratching bronchial epithelial cells (BECs) was utilized to investigate the function of IQGAP1. The results showed that IQGAP1 was abundant in BECs of mouse, rat, pig and human. IQGAP1 was colocalized with tubulin cytoskeleton, but was destroyed by nocodazole, a microtubule disassembly reagent. IQGAP1 mRNA and protein expressions increased at 6-9 h after scratching. In addition, overexpression of IQGAP1 translocated β-catenin from the cytoplasm into the nucleus and activated the Tcf/Lef signal. Scratching altered the associations of IQGAP1 with β-catenin, adenomatous polyposis coli (APC) and cytoplasmic linker protein-170 (CLIP-170). Silencing IQGAP1 expression by small interference RNA (siRNA) blocked the wound closure. It is concluded that IQGAP1 signal is involved in the wound closure of BECs induced by scratching.

AIM:To explore the inhibitive effects of cervical lymphadenectomy on kerstoplasy after alkaline burns.METHODS:The Wistar rats' corneas were transplanted into Sprague-Dawley(SD)rats' eyes which were randomly divided into 4 groups:group A(control group);group B,the cervicallymphadenectomy group;group C,corneal transplantation after the alkali burn injury;group D,cervical lymphadenectomy following group C.Out of 6 rats in each group,the cornea of one rat Was used for mawophage immunohistochemistry at day 14 after the transplantstion,and the remaining 5 rats were used for studying corneal immune rejection with a slit lamp.The time when allograft rejection occurred was recorded and mean survival times(MST)were compared among the groups.RESULTS:Compared with the MST of group A(10.40±1.14 days),the MST of group B(46.30±9.46 days)Was significantly longer(P＜0.05).MST of grafts between group C(7.00± 1.58 days)and group D(15.00±3.39 days)was also significant (P＜0.05).At 14th day after the transplantation,there was no CD68 immunoreactivity in the graft of group B,and CD68 proteins were expressed to some extent in the grafts of group A and D.However,in the graft of group C,the expression of proteins Was dramatically up-regulated.CONCLUSION:Cervical lymphadenectomy therapy has a significant effect in preventing corneal allograft rejection in normal and alkali burned oorneai beds.
ABSTRACT
The effect of glycogen synthase kinase 3beta (GSK3beta) has been repeatedly implicated in cell proliferation, but studies on the effect of GSK3beta in different cell lines with different stimuli have drawn different conclusions. To investigate the direct effect of GSK3beta on cell growth in human lung adenocarcinoma cell line A549, we changed its activity by transient transfection with two kinds of GSK3beta mutant plasmids, constitutively active form S9A-GSK3beta and dominant negative form KM-GSK3beta. Twenty-four hours later, cell counting, flow cytometry and Western blot detection were made respectively. The results showed that enhancing GSK3beta activity caused a decrease in cell number, as well as a higher percentage of cells at G(1) phase. Further, the expression of cyclin D1 was down-regulated by GSK3beta. Taken together, our observations suggest that GSK3beta may induce G(1) cell cycle arrest in a cyclin D1-dependent fashion and therefore possibly plays a growth-inhibitory role in A549 cells.

The NA genes of 395 strains of human H3N2 influenza virus isolated from 1996 to 2005 in China were sequenced, analyzed with bioinformatics tools. The NA nucleotide sequence of phylogenetic tree showed a main evolution branch with multiple short side branches. The strains in the same year may be divided into several branches. There was an obvious lag between vaccine strains recommended by WHO and the Chinese circulating strains in phylogenetic tree of the NA nucleotide. The result also showed no amino acid deletion and insertion in the NA. In NA antigen sites, where including residues 197-199 aa, 431-434 aa and 339-347aa the mutation was higher, in contrast, the residues including 153 aa, 328-336 aa, 367-370aa and 400-403 aa, the mutation was lower. Besides the antigenic determinant sites, there also had the other amino acid mutated highly, such as 18, 23, 30, 93, 143, 208, 216, 221, 249, 265, 267, 307, 385 and 437 aa, among them 143 and 267 mutation were higher than that in antigenic determinant sites, their biological significance are not clear yet. The neuraminidase active-site residues in NA were highly conservative and the same were the disulphide bond and the glycosylation sites in NA. In conclusion, our analysis provides some information for influenza prevention and control and the NA inhibitor medicine application.
