ABSTRACT
Objective:To observe the effect of microelectronic EMG bridge (EMGB) training on the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury. Methods:From March, 2016 to March, 2017, 20 patients with complete cervical 5 spinal cord injury were randomly divided into control group (n = 10) and experimental group (n = 10). The control group received routine wrist extensor muscle training, and the experimental group received EMGB training in addition, for 180 days. The motor function of the affected limb was evaluated by sEMG of extensor carpi radialis longus, Manual Muscle Test (MMT), Wolf Motor Function Test (WMFT) and Spinal Cord Lesion Independence Measure (SCIM). Results:After treatment, the peak value and average value of sEMG of extensor carpi longus of both sides increased in both groups (t > 2.510, P < 0.05), the peak value and average value of the left side were higher (t > 2.759, P < 0.05), and the peak value of the right side was higher (t = 2.691, P < 0.05) in the experiment group than in the control group, however, there was no significant difference in average value of the right side between two groups (t = 2.063, P = 0.054). The scores of MMT increased in both groups (t > 2.569, P < 0.05), and were higher in the experimental group than in the control group (t > 2.278, P < 0.05). The scores of WMFT and SCIM increased in both groups (t > 3.839, P < 0.05), however, there was no significant difference between two groups (t < 1.498, P > 0.05). Conclusion:EMGB training could improve the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury.
ABSTRACT
Objective To compare the incidence of contrast-induced acute kidney injury(CI-AKI) following iso-osmolar iodixanol or low-osmolar iohexol administration in patients with acute myocardial infarction(AMI)undergoing emergent percutaneous coronary intervention(PCI). Methods The study was a prospectiverandomized controlled study.Consecutive patients with AMI were assigned to either the iodixanol group or the iohexol group randomly after they were categorized in different group according to the infarcted walls(inferior and anterior infarction)indicated by electrocardiogram. The primary end point was the incidence of CI-AKI,which is defined as serum creatinine(sCr)increase>25% or>0.5 mg/dl(44 μmol/L)from baseline witin 72 hours. Results Two hundred ninety-seven patients were enrolled and allocated to the iodixanol group(n=149)or the iohexol group(n=148),and CI-AKI occurred in 22.1% of patients in the iodixanol group and 16.9% of patients in the iohexol group (95% confidence interval –14.2% to 3.8%,P for noninferiority<0.002). The incidence of CI-AKI was higher in the anterior infarction group than in the inferior infarction group(21.4% vs. 11.6%,P<0.01). Conclusions In patients with AMI who underwent emergent PCI,iohexol was not inferior to iodixanol on the incidence of CI-AKI,and it is reasonable to avoid selection bias for assigning patients into inferior and anterior infarction group according to the infarcted walls for the future CI-AKI related clinical study.

ABSTRACT
Objective To discuss the clinical features of cerebral schistosomiasis. Methods The clinical data of fourteen patients with cerebral schistosomiasis from March 2010 to March 2016 were collected and analyzed retrospectively. Results The schistosomiasis immunological tests of sera and cerebrospinal fluids from the fourteen patients were all positive. Eosinophils increased in ten cases,and the proportion was 5.1％-60.3％. Schistosoma eggs were found in seven cases by the fecal Kato-Katz method. Fourteen cases were all infected with Schistosome japonicum. Twelve cases were diagnosed as chronic type,and two cas-es as acute type. Thirteen patients received medical treatment,of which twelve were cured,and one improved. One patient re-ceived the surgical resection of the lesion. Conclusion The clinical manifestations of cerebral schistosomiasis mainly include seizure,headache,dizziness and fever. In the enhanced head magnetic resonance imaging(MRI),the lesions are clustered and merged into lumps,which is the characteristic image of cerebral schistosomiasis japonica. The praziquantel treatment can achieve a good prognosis.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the safety and efficacy between endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy ( EST) for common bile duct stones using meta-analysis method.</p><p><b>METHODS</b>Randomizd controlled trials comparing EPBD with EST for common bile duct stones and published from January 1990 to July 2012 were recruited. This meta-analysis was conducted to estimate short-term and long-term complications. Fixed random effect model or random effect model was established to analyze the data.</p><p><b>RESULTS</b>Twelve randomizd controlled trials were included in this analysis. These studies included 1865 patients, 925 of them were treated with EPBD and 940 were treated with EST. The analysis of basic characteristics of these included studies showed that: compared to EST, patients in the EPBD group were younger (OR = -1.16, 95% CI: -1.49 to -0.84, P = 0.00), while in two groups, there were no significant difference (P > 0.05) in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the number of merged duodenal diverticulum, common bile duct diameter, the total follow-up time. Also, compared to EST, the overall stone clearance in the EPBD group was lower (OR = 0.64, 95% CI: 0.42 to 0.96, P = 0.03), pancreatitis incidence was higher (OR = 2.67, 95% CI: 1.61 to 4.43, P = 0.00), incidence of bleeding (OR = 0.12, 95% CI: 0.04 to 0.34, P = 0.00), acute cholecystitis (OR= 0.39, 95% CI: 0.18 to 0.84, P = 0.02), total long-term complication rate (OR = 0.53, 95% CI: 0.36 to 0.77, P = 0.01), stone recurrence rate more than a year were lower (OR= 0.48, 95% CI: 0.26 to 0.90, P = 0.02). While in two groups, there were no significant difference (P > 0.05) in the stone removal on 1 '' attempt, the total near-term complications and acute cholangitis.</p><p><b>CONCLUSIONS</b>On the basis of lower rates of bleeding, EPBD seems to be preferred strategy over EST for endoscopic remove of common bile duct stones in patients who have coagulopathy. Although stone recurrence rate more than a year of EPBD is lower, but the overall stone clearance rate is lower and the risk of pancreatitis is higher than that of EST.</p>

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.
ABSTRACT
Study on features of acupoints with resistance test in the past half century is reviewed in this article. Mechanism and technology of the method are introduced as well as its shortcomings. The determination method of signal transmission along meridians with the combination of electrical network theories and practice is advanced. And the result of a series experiments on one meridian at the superficial part of the body are given as well. Thus, it is concluded that the signals of the point-in/point-out and the signals along a non-meridian path with the same distance are significantly different, which gives a verification of the feasibility of the method by using electrical network theories to set out characteristics of signal transmission along meridians dynamically.

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.
ABSTRACT
<p><b>OBJECTIVE</b>Solar ultraviolet (UV) radiation is an important environmental factor that affects human health. The understanding of diurnal variations of UV radiation at anatomical sites may be helpful in developing ways to protect humans from the harmful effects of UV radiation.</p><p><b>METHODS</b>In order to characterize the diurnal variations, the UV exposure values were measured at 30 min intervals by using Solar-UV Sensors and a rotating manikin in Shenyang city of China (41 degrees 51'N, 123 degrees 27'E). Measurement data for four representative days (in each of the four seasons respectively) were analyzed.</p><p><b>RESULTS</b>The diurnal variations in solar UV radiation at the shoulder, the forehead and the chest were similar to those associated with a horizontal control measurement. However, the diurnal variations at the eye and the cheek exhibited bimodal distributions with two peaks in spring, summer and autumn, and a unimodal distribution in winter. The UV exposure peaks at the eye and the cheek were measured at solar elevation angles (SEA) of about 30 degrees and 40 degrees , respectively.</p><p><b>CONCLUSION</b>The protection of some anatomical sites such as the eye from high UV exposure should not be focused solely on the periods before and after noon, especially in the places and seasons with high SEA.</p>

<p><b>OBJECTIVE</b>To study the effects of strychnos alkaloids on the proliferation of adult rat neuroprogenitor cells.</p><p><b>METHODS</b>Strychnos alkaloids free of strychnine and brucine were extracted from Strychnos nux vomica, and the effects of Strychnos alkaloids on the survival of HEK293 and PC12 cells were evaluated using MTT assay. In vitro cultured adult rat neuroprogenitor cells isolated from the hippocampus were treated with different concentrations of Strychnos alkaloids for 2 days, and the cell proliferation was assessed using BrdU incorporation assay.</p><p><b>RESULTS</b>At the concentration above 0.5 mg/ml, Strychnos alkaloids produced toxic effect against HEK293 cells (P<0.0001), while for PC12 cells, Strychnos alkaloids inhibited the cell survival at the concentration as low as 5 microg/ml (P<0.0001). After 2 days of exposure to 50 microg/ml Strychnos alkaloids, the neuroprogenitor cells showed significantly decreased number of BrdU-positive cells (P<0.01), but the total cell number remained stable when compared with that of the control cells (P>0.05), whereas at the concentration of 100 microg/ml, Strychnos alkaloids produced obvious cytotoxicity against the neuroprogenitor cells.</p><p><b>CONCLUSION</b>Strychnos alkaloids can significantly inhibit the proliferation of adult rat neuroprogenitor cells, and this effect is probably selective, suggesting the potential of Strychnos alkaloids as a new drug for treatment of neurocytoma.</p>
