·AIM:To study the effects of phacoemulsification on ocular surface and corneal endothelial cells in cataract patients with diabetes mellitus.·METHODS:This study used a retrospective analysis of the clinical data to compare curative effect, the research object was 98 cases ( 98 eyes ) of cataract patients with phacoemulsification from January 2016 to December 2016 in our hospital. Patients were divided into the observation group and the control group according to whether diabetes merged. The observation group had 50 cases of cataract patients with diabetes, the control group had 48 cases of pure cataract patients. Two groups of patients underwent phacoemulsification surgery and transparent corneal incision, surgeries were completed by the same doctor, no xeroma before surgery. Preoperative glycemic control was normal for diabetic patients, no changes in eye fundus. Observation of ocular surface at postoperative 1, 3, 7d and 1mo was taken. Dry eye symptoms, lacrimal film breakup time ( BUT ) , corneal fluorescein staining ( FL ) score, SchirmerⅠtest ( SⅠt ) and corneal endothelial cell density were compared.·RESULTS: Dry eye symptom score of the two groups before and after operation had significant difference;data of the observation group at postoperative 7d and 1mo was significantly higher than that of the control group, there was statistical significance (P<0. 05), there was no significant difference at 1 and 3d after operation (P>0. 05 ). BUT of the two groups before and after surgery showed significant difference; data of the observation group at 7d and 1mo after operation was significantly lower than that of the control group, there was statistical significance ( P<0. 05 ); at 1 and 3d after operation there was no significant difference (P>0. 05). The FL score of the two groups before and after surgery had significant difference, and at 3, 7d and 1mo after operation, data of the observation group was significantly higher than that of the control group, there was statistical significance ( P< 0. 05 ); there was no significant difference at postoperative 1d (P>0. 05). The two groups' before and after surgery SⅠt had significant difference, at 1, 3, 7d and 1mo after operation, data of the observation group was significantly higher than that of the control group, there was statistical significance (P< 0. 05 ). Corneal endothelial cell density showed apparent difference of the two groups before and after surgery;at 1, 3, 7d and 1mo after operation, data of the observation group was significantly lower than that of the control group, there was statistical significance ( P<0. 05).· CONCLUSION: Phacoemulsification has significant effects on tear film break-up time, SⅠt and dry eye symptoms in patients with diabetes mellitus, which may be related to the impaired repair ability of diabetic patients.

To explore the method of explants directly induced bud and establish the tissue culture system of mutiple shoot by means of direct organogenesis, core bud and daughter bulbs (the top of bud stem expanded to form daughter bulb) of T. edulis were used as explants and treated with thidiazuron (TDZ) and 1-naphthlcetic acid (NAA). The results showed that the optimal medium for bud inducted form core bud and daughter bulb were MS + TDZ 2.0 mg x L(-1) + NAA 4.0 mg x L(-1) and MS +TDZ 2.0 mg x L(-1) + NAA 2.0 mg x L(-1) respectively, both of them had a bud induction rate of 72.92%, 79.22%. The optimal medium for cluster buds multiplication was MS + TDZ 0.2 mg x L(-1) + NAA 0.2 mg x L(-1), and proliferation coefficient was 2.23. After proliferation, cluster buds rooting occurred on MS medium with IBA 1.0 mg x L(-1) and the rooting rate was 52.6%, three to five seedlings in each plant. Using core bud and daughter bulb of T. edulis, the optimum medium for adventitious bud directly inducted from daughter bulb, core bud and cluster bud multiplication were screened out and the tissue culture system of multiple shoot by means of direct organogenesis was established.

OBJECTIVETo examine the relationships between overweight, obesity and indices as satisfaction of life, trait anxiety, depression, self concept etc. in male and female junior middle school students.

METHODSA questionnaire survey was administered to 1818 participants in a middle school in Hefei city, Anhui province. This contents of survey would include Multidimensional Students' Life Satisfaction Scale (MSLSS), Center for Epidemiologic Studies Depression Scale (CES-D), Trait Anxiety Inventory (TAI), and Piers-Harris Children's Self Concept Scale (PHSCS). Anthropometric measures were taken together with the calculation of body mass index (BMI). The students were divided into normal-weight, overweight and obesity groups by BMI separate criteria. Gender differences of mental health status and group differences of mental health among normal-weight, overweight obesity students were analyzed. Relationships between BMI and the scores of MSLSS, CES-D, TAI, PHSCS were estimated among boys and girls respectively.

RESULTSThe prevalence rates of overweight and obesity of boys (21.5%, 7.7%) were significantly higher than in girls (8.0%, 2.8%). Difference of the MSLSS scores in gender was significant among normal-weight group (P = 0.002). The difference of the CES-D scores in gender was significant among overweight group (P = 0.046). There were significant group differences of the CES-D scores, TAI scores, and PHSCS scores among normal-weight, overweight and obese girls (P < 0.05). Both the CES-D score and TAI score of obese girls were higher than normal-weight girls (P = 0.012 and P = 0.035). The PHSCS score of obese girls was lower than normal-weight girls (P = 0.014) and the group difference of the CES-D score was also significant between overweight and normal-weight girls (P = 0.025).

CONCLUSIONBoth prevalence rates of overweight and obesity of boys were higher than that in girls. Nevertheless, level of mental health level among girls with overweight and obesity were lower than that in boys.

Objective To make epidemiological investigation on children and teenagers with congenital heart disease (CHD) from October 2015 to November 2016 in three counties in Zhaotong area. Methods The examination was divided into the following two phases: primary screening, secondary screening. Standardized echocardiographic examination was performed for the students with suspected CHD. we combined comprehensive analysis of electrocardiogram, X-ray and cardiac catheterization to make a clear diagnosis for patients. The index of prevalence rate of CHD, the types of the disease, and gender of the patients in 14957 children and teenagers were statistically analyzed. Results Altogether 61 cases of CHD were discovered. The total prevalence of CHD was 4.08‰ (61 of 14957 cases), the prevalence rate in male was 4.55‰, in female was 3.61‰, No difference of the prevalence rate was found between male and female (χ2=0.823, P＞0.05);the difference among different age groups had no statistical significance (χ2=4.692, P＞0.05);The prevalence rate of CHD in Qiaojia was 5.17‰, in Daguan was 6.36‰, and in Zhenxiong was 3.03‰, There was no significant difference in the prevalence rate among different countries (χ2=5.897, P＞0.05). In terms of the types of the disease, atrial septal defect accounted for the first (37.7％ ), followed by ventricular septal defect (26.2％ ) and patent ductus arteriosus (19.7％ ), others types of CHD were rare. Conclusion The prevalence of CHD in investigated area is slightly higher than the average level of the nationwide. The main types of CHD are atrial septal defect, ventricular septal defect and patent ductus arteriosus.

OBJECTIVETo investigate the recovery duration of manual lifting tasks.

METHODS30 college student volunteers with gender equally distributed were involved in the simulated stoop-, squart- and semi squart-lifting tasks in the laboratory. Signals of electromyography (EMG) at the back muscles (left and right thorax m. erector spinae, LT(10) and RT(10); left and right lumbar m. erector spinae, LL(3) and RL(3)) and electrocardiography (ECG) were recorded during the rest intervals. The percentage of maximum voluntary electrical activation (MVE%), EMG median frequency (MF), and heart rate (HR) were analyzed to predict the recovery time required.

RESULTSDuring the break, MVE% at 4 back muscles of all the male subjects were recovered to resting level within 5 minutes and 91.8% were within 2 minutes. Except for RL(3) after squat- and stoop-lifting task, the MVE% of female subjects went back to resting level within 3 minutes and 67.8% were within 2 minutes. The MF of male subjects were recovered in 10 minutes and 74.9% within 2 minutes, with the exception of RL(3) after stoop- and squat-lifting tasks. All the female MF were recovered in 8 minutes and 83.4% were within 2 minutes. However, during the last 20 minute break after the lifting tasks, the MVE% and MF of all male and female subjects were recovered, while HR came back to resting level within 14 and 5 minutes, respectively.

CONCLUSIONSFor the three manual lifting tasks with 25% MVC workload lasting for 4.5 min, a break of 15 minutes is sufficient for most erectors spinae to recover from local muscle load. However, in terms of the HR, a break of 15 minutes is enough for the recovery of systematic load.

Objective · To explore the association between cerebrospinal fluid (CSF) protein level and peripheral nerve demyelination in patients with Guillain-Barré syndrome (GBS). Methods · Clinical and biochemical data of 86 patients with GBS were retrospectively analyzed. According to electromyograms examination of peripheral nerve, GBS patients were divided into group with demyelination and group with axonal degeneration, and their clinical and biochemical characteristics were compared between the two groups. The correlation between CSF protein level and peripheral nerve demyelination was assessed by Spearman's correlation analysis. Results · Between the group with demyelination and group with axonal degeneration,there was no significant difference in gender, age, Hughes score, respiratory infection, gastrointestinal infection, erythra, ganglioside sodium injection and immunoglobulin G (IgG) index (P>0.05). Significant higher level of CSF protein, CSF albumin/serum albumin, IgG, and 24 h IgG intrathecal synthesis rate were detected in group with demyelination than that of in group with axonal degeneration (P<0.01). CSF protein level was positively correlated with peripheral nerve demyelination (r=0.345, P=0.001). Conclusion · The incidence of peripheral nerve demyelination increased accompanied with CSF protein level, and analysis of CSF protein level may be helpful in investigating the immunologic mechanism of peripheral nerve demyelination in GBS patients.

BACKGROUNDAcute-on-chronic hepatitis B liver failure (ACLF-HBV) is a clinically severe disease associated with major life-threatening complications including hepatic encephalopathy and hepatorenal syndrome. The aim of this study was to evaluate the short-term prognostic predictability of the model for end-stage liver disease (MELD), MELD-based indices, and their dynamic changes in patients with ACLF-HBV, and to establish a new model for predicting the prognosis of ACLF-HBV.

METHODSA total of 172 patients with ACLF-HBV who stayed in the hospital for more than 2 weeks were retrospectively recruited. The predictive accuracy of MELD, MELD-based indices, and their dynamic change (D) were compared using the area under the receiver operating characteristic curve method. The associations between mortality and patient characteristics were studied by univariate and multivariate analyses.

RESULTSThe 3-month mortality was 43.6%. The largest concordance (c) statistic predicting 3-month mortality was the MELD score at the end of 2 weeks of admission (0.8), followed by the MELD: sodium ratio (MESO) (0.796) and integrated MELD (iMELD) (0.758) scores, DMELD (0.752), DMESO (0.729), and MELD plus sodium (MELD-Na) (0.728) scores. In multivariate Logistic regression analysis, the independent factors predicting prognosis were hepatic encephalopathy (OR = 3.466), serum creatinine, international normalized ratio (INR), and total bilirubin at the end of 2 weeks of admission (OR = 10.302, 6.063, 5.208, respectively), and cholinesterase on admission (OR = 0.255). This regression model had a greater prognostic value (c = 0.85, 95%CI 0.791 - 0.909) compared to the MELD score at the end of 2 weeks of admission (Z = 4.9851, P = 0.0256).

CONCLUSIONSMELD score at the end of 2 weeks of admission is a useful predictor for 3-month mortality in ACLF-HBV patients. Hepatic encephalopathy, serum creatinine, international normalized ratio, and total bilirubin at the end of 2 weeks of admission and cholinesterase on admission are independent predictors of 3-month mortality.

OBJECTIVETo describe the different sex, age and grade distribution of coping behavior and its psychological effects on weight, and to analyze the correlation between overweight, obesity and unhealthy psycho-behaviors related to weight control in adolescents.

METHODSA survey was conducted among students of grade 1 and grade 2 at a junior middle school in Hefei. Students completed the anonymous. questionnaire including the demographic characteristics of adolescents and parents, self-assessed weight status and adolescents' psycho-behaviors related to weight control. Anthropometric measures were taken together with body mass index (BMI) calculated. Students were divided into obesity,overweight and control groups by BMI separate criteria and by self reporting, respectively.

RESULTSAmong all the students, 17.4% reported having unhealthy psychological feelings related to weight control including 3.8% reported having unhealthy behaviors related to weight control and 19.1% of them reported having unhealthy psycho-behaviors related to weight control. The rates of unhealthy psychological feelings, unhealthy behaviors and total unhealthy psycho-behaviors related to weight control among girls (20.6%, 4.3%, 22.6%) were all higher than those among boys (14.5%, 3.3%, 15.8%) (P < 0.05). The rates of unhealthy psychological feelings, unhealthy behaviors and total unhealthy psycho-behaviors related to weight control in obese individuals both assessed by BMI and assessed by self reporting appeared to be the highest (P < 0.05). In addition,data showed that obesity and overweight assessed both by BMI separate criteria and by self-reporting appeared positive correlations with the rates of unhealthy psycho-behaviors related to weight control. Moreover, the relationship between obesity or overweight assessed by the two methods and unhealthy psycho-behaviors related to weight control did not alter by other factors.

CONCLUSIONUnhealthy psycho-behaviors related to weight control of girls are more severe than boys. The relationship between obesity and unhealthy psychological feelings and behaviors related to weight control does not alter by other factors such as social factors.
