Objective To explore the physical and mental health status on the ‘left behind ’ students in Anhui province and the related influential factors.Methods Stratified cluster sampling method was used to investigate the 682 out of 3421 students from 7 middle schools in both south and north Anhui province,using multidimensional sub-health questionnaire of adolescents (MSQA) and mental health test (MHT),for assessment of the general condition,physical and mental health status.Results 14.22％ of the ‘left behind’ students were in sub-health condition compared to 11.28％ among the normal students,and the mental sub-health status represented 13.64％ for the former and 10.84％ for the latter.In addition,the ‘left behind’ students appeared less content with their life than those of staying with their parents (P＜0.05).MHT scores in the subjects were positively correlated with the scores on MSQA and showed significant difference (P＜0.01).Results from the multiple linear regression analysis showed that the mental health condition among the left behind students was in linear regression relationship with the decreased physical activity (β =1.456,P=0.001 ),emotional problems (β =1.096,P=0.000 ) and problems of social adaptation (β=1.011,P=0.006).The status of physical sub-health in the Anhui province showed that there was no significant difference in each of the study group (P＞0.05).Conclusion Decreased physical activity and emotion aporia as well as difficult social adaptation were major factors leading to degenerated mental health levels in the‘left-behind’ adolescents.The findings suggested that the mental health status could be improved inthis population through better management on their body-health condition.

Objective By exploring the mental health situation of the unattended adolescents in Anhui province. This study aimed at investigating the status of mental health and related influential factors to provide evidence for effective strategies and intervention in physical and mental health improvement of this population. Methods By using stratified cluster sampling method, we conducted an investigation on 3421 subjects,in which 682 were unattended adolescents,from 7 middle schools in both south and north parts of Anhui province. MHT was used to assess the general condition and status of mental health in the adolescents. Results In the population aged 10 to 18 in Anhui province,19.94% of them were unattended adolescents and were found with poor mental health and more prone to loneliness, sensitive and stronger fear as compared with those with parents around, which showed statistical difference (P＜0.05). As for the mental health status of unattended adolescents in different family types, the subjects seemed worse in the north than in the south Anhui regarding the total scores of MHT, self-accusation, physical symptoms and phobic anxiety disorder (P＜0.05). Girl students were also inferior to boys concerning the total scores of MHT, learning anxiety, interpersonal anxiety, self-accusation, sensitivity, physical symptoms and impulsive behavior (P＜0.05). The students in Grade 7 scored lower than those of the upperclassmen on MHT (P＜0.05), and the subjects from township were superior to those of rural areas regarding interpersonal anxiety and loneliness (P＜0.05). Children with siblings appeared worse than their counterparts on the total scores of MHT, including the items of interpersonal anxiety, learning anxiety, self-accusation, sensitivity,physical symptoms, strong fear and impulsive behavior (P＜0.05). Conclusion Generally, the mental health status of unattended adolescents in Anhui province appeared poorer than their counterparts, and relatively worse psychological status was seen in girls, high school students,children with siblings and subjects living in north Anhui or rural areas.

OBJECTIVETo evaluate the safety and efficacy and summarize the initial experience of transcatheter aortic valve implantation (TAVI) for treating patients with severe aortic stenosis.

METHODSFrom October 2010 to May 2011, TAVI using 18 F Corevalve system was applied in 3 patients with severe calcified aortic valve stenosis at high risk for surgery. The efficacy and complications of the procedure were analyzed and the procedure experiences were summarized.

RESULTSTAVI procedure was successful in all 3 cases. The mean operation time was (109.0 ± 22.6) minutes and X-ray exposure time was (24.0 ± 9.5) minutes. The peak pressure gradients after surgery were significantly reduced [from (84 ± 15) mm Hg (1 mm Hg = 0.133 kPa) to (6 ± 3) mm Hg]. A trivial to mild paravalvular leak was observed in all patients post procedure. Case 1 was free from perioperative complications. Case 2 experienced a transient complete left bundle branch block. Case 3 developed 3 degree atrioventricular block and implanted with a permanent cardiac pacemaker, cardiac tamponade which was relieved through conservative treatment, including pericardial puncture and drainage and acute kidney injury.

CONCLUSIONSOur initial experience showed that TAVI using the 18 F Corevalve system is safe and effective for patients with severe calcified aortic valve stenosis at high-risk for surgery, though the procedure may cause some complications. Strict patient selection and proficient surgical techniques may reduce the incidence of complications.

OBJECTIVETo investigate the cause of an outbreak characterized by diarrhea and vomit in a middle school in Huzhou City.

METHODSComprehensive analysis was conducted based on field epidemiological study, clinical characteristics of the cases and laboratory test.

RESULTS578 cases of acute gastroenteritis were found. The attack rate was 23.58%. The most frequently observed clinical symptoms were diarrhea, vomiting, abdominal pain and nausea. Some few had fever. Most cases had slight clinical symptom with a course from 1 to 3 days. The cases were distributed in every class, showing no phenomenon of clustering. Norovirus were detected in 11 out of 15 stool samples by using RT-PCR. 6 were genogroup II norovirus. 3 were genogroup I norovirus. enogroup I and II norovirus were detected at the same time in 2 stool samples (the same student with 2 tests). Case-control study showed that drinking unheated bottled water was risk factor (OR = 2.46, 95% CI = 1.19-5.23), and had a dose response relation with the disease (chi = 24.8 P < 0.01). The epidemic was controlled soon through isolating patients during treatment, providing boiled water, disinfecting and health education.

CONCLUSIONThis was an infectious diarrhea outbreak caused by norovirus. The suspected transmission ways were drinking unheated bottled water and contact daily.

Comminuted fracture of distal femur is a common lower limb injury from traffic accidents, especially from motor accidents. Routine dynamic condylar screw (DCS) or 95-degree condylar plate (CP) sometimes cannot solve the bone defect in the center of alignment and contralateral diaphysis for the reason of absent screw anchor point, especially for AO C2.2-2.3 types. Many authors recommended open reduction and fixation with less invasive stabilization system (LISS) as the treatment of choice, but there are still problems in fusion and alignment. In this study, we reported our experiences with the use of bone splint technique in the high-energy commimuted fracture of distal femur with central and medial bone defect in adolescents.

Objective To explore surgical treatment of gliomas involving the motor eloquent area. Methods Twelve cases of gliomas involving precentral gyrus were underwent awake surgery procedures assis- ted with neuronavigation and brain functional mapping by cortical electrical stimulation.Results Eleven ca- ses acquired accurate location of both lesions and eloquent areas by neuronavigation and direct cortical stimula- tion.7 cases of motor cortices and 2 cases of motor speech centers were confirmed during the operation.Re- section,verified by postoperative MRI,was total in 8 cases (66.7%) and subtotal in 4 patients.Histological examination revealed an infiltrative glioma in all cases (8 low grade astrocytomas,2 high grade astrocytomas and 2 glioblastoma).Four patients had no postoperative deficit,while the other 8 patients were impaired, with,in all cases except one,complete recovery in 7 days to one month.Conclusion Direct cortical elec- trical stimulations and awake surgery offer a reliable,precise and safe method,allowing functional mapping es- pecially useful in case of infiltrative cerebral tumors in eloquent areas.This technique allows improvement in the quality of tumoral resection and concurrently a minimization of the risk of definitive postoperative neurologi- cal deficit.

OBJECTIVETo compare the efficacy of telbivudine monotherapy and telbivudine combination therapy with adefovir in patients with nucleos(t)ide-naive chronic hepatitis B, high-level hepatitis B virus (HBV) load and hepatitis B e antigen (HBeAg)-positivity, and to explore the relationship between treatment regimen adherence and treatment outcomes.

METODSA retrospective study was performed with 123 HBeAg-positive, high-level viral load (HBV DNA≥10(7) copies/ml), nucleos(t)ide-naive chronic hepatitis B patients. Fifty-three of the patients received combination therapy with telbivudine and adefovir dipivoxil,while 70 patients received the telbivudine monotherapy. All patients were tested for rates of conversion to HBV DNA-negative status,alanine aminotransferase (ALT) normalization, HBeAg seroconversion, drug resistance, and side effects at treatment weeks 12, 24, and 48. Treatment regimen adherence was assessed through self-reporting, and interviews were used to explore the relationships to treatment outcomes. The chisquare test, t test and Fisher's exact test were used for statistical analyses.

RESULTSThe rates of HBV DNA negative conversion in the combination group at treatment weeks 12, 24 and 48 were 62.3% (33/53), 88.7% (47/53) and 94.3% (50/53) and were significantly different from those in the monotherapy group at weeks 12 and 24.The rates of ALT normalization were significantly different between the two groups at treatment week 12 (94.3% vs. 77.1%). The rate of HBeAg seroconversion in the combination group at treatment week 48 was 39.6%, and significantly different than that of the monotherapy group. The rates of drug-resistance in the combination and monotherapy groups at treatment week 48 were 3.8% and 11.4%, and the proportion of non-adherence to the treatment regimen was 53.3%, which significantly affected treatment outcome. No side effects occurred in either treatment group.

CONCLUSIONTelbivudine combination treatment with adefovir was more effective than telbivudine monotherapy and elicited a low drug resistance rate in nucleos(t)idenaive chronic hepatitis B patients with high-level HBV load and HBeAg-positivity. Adherence to the therapy regimen was a key factor influencing treatment outcomes.

OBJECTIVETo investigate the efficacy of heated humidified high-flow nasal cannula (HHHFNC) and nasal continuous positive airway pressure (nCPAP) in preterm infants aged 26-31(+6) weeks with respiratory distress syndrome after ventilator weaning.

METHODSA total of 161 preterm infants were randomly divided into two groups after ventilator weaning: HHHFNC treatment (n=79) and nCPAP treatment (n=82). The two groups were subdivided into 26-28(+6) weeks and 29-31+6 weeks groups according to the gestational age. The treatment failure rate, reintubation rate within 7 days after extubation, incidence of complications, and mortality during hospitalization were compared between the two groups.

RESULTSThe treatment failure rate and reintubation rate showed no significant differences between the HHHFNC and nCPAP groups. The preterm infants aged 26-28(+6) weeks in the HHHFNC group had a significantly higher treatment failure rate than those in the nCPAP group (P<0.05), while the reintubation rate showed no significant difference. As for the preterm infants aged 29-31(+6) weeks, the treatment failure rate and reintubation rate showed no significant differences between the two groups. The incidence of complications and mortality showed no significant differences between the HHHFNC and nCPAP groups.

CONCLUSIONSIn preterm infants aged 29-31(+6) weeks, HHHFNC has a similar efficacy as nCPAP after ventilator weaning, while in those aged less than 29 weeks, HHHFNC should be used with great caution if selected as the first-line noninvasive respiratory support.
