ABSTRACT
@#Abstract: Objective To understand the density changes and seasonal fluctuation of larvae and adults of Aedes albopictus in Hainan Province from 2017 to 2021, and to provide a scientific basis for the prevention and control of dengue fever and other vector-borne diseases in Hainan Province. Methods The Breteau index method was used to monitor the larvae of Aedes mosquitoes, and the breeding sites of all small indoor and outdoor water containers and their larvae was checked and recorded. The adult mosquitoes were monitored by double lamination and light trap. Results A total of 1 962 adult female Aedes albopictus mosquitoes were captured in Hainan Province from 2017 to 2021, accounting for 2.17% of the total captured mosquitoes. There were significant differences in mosquito species composition in different habitats in different years (χ2=312.258, P<0.01). In 2017, the density of mosquitoes in livestock sheds was the highest (9.71 per lamp·night), but the composition ratio of Aedes albopictus was the lowest (1.29%). In 2020, the mosquito density in hospitals was the lowest (2.22 mosquitoes per lamp·night), and in 2019, the proportion of Aedes albopictus in residential areas and hospitals was the highest (3.27% on average).The mosquito density in different habitats was the lowest in 2020. The proportion of Aedes albopictus in residential areas and livestock sheds showed an increasing trend from 2017 to 2021, while the proportion of other habitats showed significant fluctuations. The proportion of Aedes albopictus in hospitals showed an obvious decreasing trend in 2020. From 2017 to 2021, the average mosquito density was 5.97, 4.26, 3.82, 3.39 and 3.68 mosquitoes per lamp·night, respectively, showing a decreasing trend year by year except 2021. Except for 2019, the lure index also showed a decreasing trend, with an average value of 1.5/(hour·net), showing a decreasing trend year by year. From 2017 to 2021, the annual average density of Aedes albopictus in Hainan Province was 0.09 mosquitoes per lamp·night, showing obvious seasonal fluctuation. The Breteau index showed a slow decline from 2017 to 2021, and its annual peak was between June and August, which was 1-2 months later than the peak of adult mosquito density. Conclusions The population density of Aedes albopictus in Hainan shows obvious seasonal characteristics. Mosquito control activities should be carried out according to the seasonal characteristics of mosquitoes to reduce the risk of dengue fever and other infectious diseases.
ABSTRACT
At present, a considerable proportion of patients with obsessive-compulsive disorder (OCD) cannot be effectively relieved by standard drug and psychotherapy, so researchers have turned their attention to new directions of physiotherapy. Repetitive transcranial magnetic stimulation (rTMS), as an adjuvant therapy for refractory OCD, is a non-invasive nerve stimulation technique. Many studies have shown that rTMS is effective in the treatment of OCD. However, there were also disputes in the selection of stimulation targets, parameter settings and so on. This article systematically combs the setting and application of standard rTMS in the treatment of OCD, and comprehensive therapeutic effect of rTMS, and then discusses the deficiency of treatment so far, in order to put forward the future development direction and promote clinical treatment progress.
ABSTRACT
Objective@#To investigate the prognostic factors of primary liver cancer treated with transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA), and then to establish a prognostic model.@*Methods@#Clinicopathological and follow-up data of 145 patients who underwent TACE combined with RFA from January 2010 to December 2012 were retrospectively analyzed. Univariate and multivariate survival analyses were performed using the Cox proportional hazards model, and the prognostic model was established.@*Results@#The 1, 2, and 3-year survival rates were 92.6%, 81.4% and 66.2%, respectively. The 3-year recurrence and metastasis rate was 64.8%.Multivariate analysis showed that female cases and higher serum albumin levels were the protective factors for the 3-year overall and relapse-free survival of patients(P<0.05 for all). High levels of alpha-fetoprotein (AFP), alanine aminotransferase (ALT), total bilirubin (TBIL), portal vein thrombosis and higher Child Pugh stages were the independent risk factors for the 3-year overall survival(P<0.05 for all). High levels of AFP, TBIL, portal vein thrombosis and advanced stages of BCLC staging (B and C) were the independent risk factors for tumor recurrence and metastasis(P<0.05 for all). The predictive model established based on the multivariate analysis showed good sensitivity and specificity. The area under ROC curve were higher than 0.90.@*Conclusions@#The prognosis of liver cancer patients treated with TACE combined with RFA is affected by various clinicopathological factors. The systematic evaluation of the relevant factors before treatment may help to select proper patients and improve prognosis.
ABSTRACT
Objective To evaluate the clinical value of CT-guided 125I particle implantation combined with iliac artery infusion chemotherapy in treating refractory and recurrent pelvic malignant tumors.Methods A total of 35 patients with refractory and recurrent pelvic malignant tumor,who were admitted to authors' hospital during the period from January 2013 to January 2016 to receive CT-guided 125I particle implantation combined with iliac artery infusion chemotherapy,were selected and used as the study group,while other 39 patients with refractory and recurrent pelvic malignant tumor received simple 125I particle implantation and were used as the control group.The short-term and long-term curative effect,as well as the improvement of clinical symptoms,were compared between the two groups.Results The objective effective rate and the benefit rate in the study group were 60.0％ (21/35) and 85.7％ (30/35) respectively,while those in the control group were 53.8％ (21/39) and 84.6％ (33/39) respectively,the differences between the two groups were not statistically significant (P=0.594 and P=0.894 respectively).In the study group the mean disease progressionfree period was 12.2 months,which was 3.6 months longer than that of 8.6 months in the control group,the difference between the two groups was statistically significant (P=0.002).The recurrence rates in the study group and the control group were 40.0％(12/30) and 57.6％ (19/33) respectively,the difference between the two groups was statistically significant (P=0.018).The mean preoperative and postoperative KPS values in the study group were 72.4 points and 82.7 points respectively,which in the control group were 68.9 points and 79.1 points respectively;in each group statistically significant difference existed between the preoperative KPS value and the postoperative one (P=0.043 and P=0.039 respectively),however,no statistically significant difference in postoperative KPS value existed between the study group and the control group (P=0.745).Conclusion For the treatment of refractory and recurrent pelvic malignant tumors,CT-guided 125I particle implantation is an effective therapy,however,combination use of iliac artery infusion chemotherapy can reduce the incidence of tumor recurrence and prolong the disease progression-free period.
ABSTRACT
Objective To investigate the feasibility and safety of the double J tube removal from ureter under fluoroscopy observation. Methods The medical records of patients in our department from April 2013 to March 2015, who performed“double J tube removal and/or replacement”were retrospectively reviewed and analyzed. These data included gender and age of the patient, position of the double J tube end in the bladder, removal method, fluoroscopy time, postoperative complications and so on. The removal methods were divided into a direct method and an indirect method. The direct method means using the ring of a gooseneck snare to hitch directly the end of double J tube in the bladder, and pulling it to the urethral orifice. For the indirect method, a guide wire and a gooseneck snare first were sent into the bladder to clip the double J tube, then, the ring of the gooseneck snare was used to hitch the end of the guide wire to withdraw the gooseneck snare and the guide wire to the urethral orifice, and the double J tube was pulled to the urethral orifice. The double J tube end position in the bladder had direct relationship with the choice of removal method. The author divided the double J tube end position in the bladder into A type, B1 type, B2 type, and C type. The bladder was divided into four quarters equally. Direct method was suitable for all types, while indirect method was only suitable for B2 and C type. Between April 2013 and September 2014, all patients were treated by the direct method;between October 2014 and March 2015, all patients with B1 and A type were treated by the direct method, and all patients with B2 and C type were treated by the indirect method. According to the success rate of operation, fluoroscopy time, the incidence of different complications, the efficacy and safety were determined. Results This study recruited a total of 49 patients, including 6 males and 43 females, who underwent 114 times of“double J tube removal”. On average, double J tube was removed 2.3 times per case. The overall success rate was 96.5% (110/114). The application of direct method was 92 times, and the success rate was 95.7%(88/92). The application of indirect method was 22 times, and the success rate was 100%(22/22). In this study, there were 4 failures to remove the double J tube, all of which happened in the direct method for the C type of patients. In the successful 110 cases, the average fluoroscopy time was (11.3+9.5) min. The application of direct method was 88 times, and the average fluoroscopy time was (12.3 ± 10.3) min; the application of indirect method was 22 times, and the average fluoroscopy time was (7.6±3.8) min. There were 10 cases with pain in urethral orifice, in which 9 cases was treated with direct method and one with indirect method. There were 5 cases with gross hematuria complicated in direct method. The overall incidence rate of the complications was 13.2% (15/114). All of postoperative complications resolved spontaneously. Conclusion The direct way and the indirect way to remove ureteral double J tube fluoroscopically are feasible and safe .
ABSTRACT
Objective To isolate, culture and identify mouse umbilical cord mesenchymal stem cells( mUCMSCs) and to study whether they can be induced to differentiate into adipocytes, chondrocytes and osteoblasts.Methods The mUCMSCs were isolated and expanded by adherent culture from fresh mouse umbilical cord.The morphological characteris-tics of the resulting cells were observed under inverted phase contrast microscope, and their expression of mesenchymal sur-face markers was identified and analyzed by flow cytometry.Then mUCMSCs were induced to differentiate into chondro-cytes, adipocytes and osteoblasts in vitro.Results Fibroblast-like cells could be isolated from the fresh umbilical cord by adherent culture.These adherent cells highly expressed mesenchymal markers including CD29, CD90 and CD105 while low expression of CD34.The cells were successfully induced to differentiate into chondrocytes, adipocytes and osteoblasts. Conclusions The mUCMSCs isolated from fresh mouse umbilical cord by adherent culture have potential of differentiation into chondrocytes, adipocytes and osteoblasts.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the impact of college students' evening exercise on their sleep quality, so as to provide a scientific basis for college students to choose an appropriate method of exercise and improve their sleep quality.</p><p><b>METHODS</b>From September to October in 2012, Multi-stage cluster random sampling method was used to select the 5997 college students in Anhui province. The status of college students' exercise and their sleep quality were investigated by the general situation questionnaire, Physical activity rating scale-3(PARS-3), Rating of perceived exertion(RPE) and Pittsburgh sleep quality index(PSQI). Kruskal-Wallis test was used to analyze the impact of evening exercise on sleep quality and multivariate unconditional logistic regression was used to analyze the factors of sleep quality in evening excise students.</p><p><b>RESULTS</b>The median of PSQI total score among 5806 college students was 5 and 1030(17.7%) students had poor sleep quality. The median of the PSQI scores was the same (5 points) for evening exercise group, daytime exercise group,daytime and evening exercise group and non-exercise group (1406, 1514, 1244, 1642 respectively). The difference was not statistically significant (χ(2) = 2.80, P = 0.42). Compared to non-exercise population, the OR (95%CI) value of evening exercise' impact on sleep quality was 0.90(0.73-1.10). Compared to very light evening exercise, the OR (95%CI) value of moderate and large amount of evening exercise' impact on sleep quality was 0.58 (0.44-0.75) and 0.67 (0.48-0.93) respectively; Compared to other sports, the OR (95%CI) value of badminton, rope skipping and jogging' impact on sleep quality was 0.72 (0.55-0.93), 0.38 (0.21-0.70) and 0.76 (0.60-0.95) respectively and they were all protective factors of sleep quality. Compared to small exercise intensity, the OR (95%CI) value of moderate, vigorous and very vigorous exercise intensity' impact on sleep quality was 1.68 (1.13-2.52), 2.38 (1.48-3.83) and 3.18 (1.72-5.90) respectively and they were harmful factors of sleep quality.</p><p><b>CONCLUSION</b>There was no impact of evening exercise on sleep quality for college students. Type of sports should be adequately chosen for evening exercise. College students can take moderate and large amount of evening exercise but should avoid activities of vigorous intensity.</p>

Objective To examine the association between folic acid supplements during peri-conception and the related adverse birth outcome.Methods Pregnant women who received first prenatal care at 4 municipal-level medical institutions in Maanshan,from Oct.2008 to Oct.2010 were selected as the target population.All participants were asked to complete a self-administered questionnaire which including data on demographic characteristics,interval,complications and frequency of taking folic acid etc.,during pregnancy.The follow-up-records after delivery would include factors as:fetal weight,height,circumference of head,chest circumference of the neonates.Finally,4448 valid questionnaires were gathered,including 190 premature,147 small for gestational age and 104 low birth weight babies.Descriptive statistics and logistic regression models were used for data analysis.Results Data showed that the weight,height and head circumference of the fetels at birth among pregnant women who had taken supplementary standard folic acid during peri-conception period or only during the first trimester,were all better than those pregnant women who had not taken the standard folic acid supplements.After adjustment for potential confounders as gestational weeks,maternal age,mather' s education level,results from the logistic regression showed that intake of standard folic acid supplements appeared a protective factor for those babies who were smaller than the gestational age (RR=0.45,95％ CI:0.24-0.86),at premature delivery (RR=0.52,95％ CI:0.32-0.87) or with low birth weight (RR=0.39,95％CI:0.19-0.80).However,data from this study showed that provision of folic acid supplements to the pre-pregnant or at first trimester alone did not make obvious impact on those babies as prematured,small for gestational age and at low birth weight.Conclusion Standardized provision of folic acid supplements during peri-conceptional period could improve the outcomes of birth.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between aggressive behaviors, parent-child separation and experience of childhood abuse among junior high school students.</p><p><b>METHODS</b>A total of 1417 students in ordinary junior high schools from 3 townships in Huoshan, Anhui were involved in this study. Self-made questionnaire was used to estimate aggressive behaviors, parent-child separation in childhood, child abuse and social demographic information of the students under this study.</p><p><b>RESULTS</b>Related scores (2.52 ± 0.78) on physical aggression in boys was higher than in girls (2.29 ± 0.79) while the scores related to anger (2.60 ± 0.82) and hostility (2.58 ± 0.80) in girls, were higher than those in boys (2.41 ± 0.75, 2.47 ± 0.78), all with statistically significant differences (P < 0.05). Scores related to different types of aggressive behaviors and the scores in total, were higher in students from the senior class (P < 0.001). Scores on items as verbal aggression, hostility and in total, were higher in those adolescents which had undergone maternal-child separation during their childhood (P < 0.05). Scores on hostility and in total, were higher in those adolescents which had suffered from father-child separation during their childhood (P < 0.05). Scores related to anger, hostility and in total, were higher in those adolescents which had undergone both parent-child separation when they were much younger (P < 0.05). Students who had suffered from various types of repeated abuse showed higher scores in various types of aggressive behaviors and in total, than those who did not have the same experience. Most of the differences among groups were statistically significant (P < 0.05).</p><p><b>CONCLUSION</b>Students that suffered parent-child separation in their earlier childhood and with repeated experiences of abuse in childhood appeared to be risk factors causing aggressive behaviors to develop during the age of adolescence.</p>

Transcatheter arterial chemoembolization (TACE) was the preferred method of non-operation treatment for hepatocellular carcinoma (HCC).Radical resection of HCC remains difficult,extrahepatic metastasis was not easy to deal with,and repeated treatment aggravated the liver injury,so the long-term efficacy was poor.Sorafenib could control tumor angiogenesis and block the proliferation of tumor cells.A male patient with primary HCC and in the stage Ⅱb according to the Chinese clinical liver cancer staging system was treated by TACE combined with sorafenib and antiviral treatment in Henan Cancer Hospital.After the treatment,the intrahepatic lesions were inactive,and the pulmonary metastasis was partially relieved.The patient was followed up till May 2012,and the survival time was 39 months.The hepatic function was normal,and the hepatitis B virus (HBV) replication was negative.No intervention treatmentrelated complications were detected,and the KPS score was 100.
ABSTRACT
Objective To investigate the association between psychological sub-healthy status and risks on injuries and related predictors among adolescents in China,in order to develop reasonable intervention programs.Methods Adolescents were selected from middle schools and colleges in eight cities.Baseline status on sub-healthy that related to psycho-pathology was measured using the Multidimensional Sub-health Questionnaire of Adolescents (MSQA).Data on Self- or unintentional injuries were collected using a standardized injury surveillance questionnaire every 3 months,for three times (T0,T1,T2 and T3).Results A total of 12 113 students completed the study.Prevalence rates related to self-injury among boys and girls were 19.4％ and 19.9％,respectively.The rates of having more than 4 types of self-injuries in boys and girls were 4.7％ and 4.2％,respectively.Boys had a significantly higher unintentional injury rate than that of girls (62.2％ vs.57.3％ ).The differences in the rates of having more than 4 types of unintentional injury between boys (3.8％) and girls (3.4％) were also statistically significant.Rates on self- and unintentional-injuries increased in T1,T2 and T3 when the psychological symptoms had an increase.Data from Multiple regression analysis demonstrated that the baseline psychological sub-healthy status was a predictive factor for higher risk of self- and unintentional- injuries at each of the follow-up waves.Conclusion Sub-healthy status of psycho-pathology was associated with an increased risk on self-and unintentional injuries among adolescents.Integrative psycho-pathological and behavioralintervention programs might help in reducing the risk of injuries among the Chinese adolescents.
ABSTRACT
Objective To explore the relationship between body mass index (BMI) and physical fitness index (PFI) among children and adolescents.Methods The study sample included 8941 students aged 7 to 18 years in Anhui who attended the Physical Fitness and Health Surveillance program of Chinese School Students,in 2010.Within each sex- and age-specific group,students were classified into five BMI categories which were:very low,BMI ＜5th percentile; low,BMI ≥5th but ＜15th percentiles; normal,BMI ≥15th but ＜85th percentiles; high,BMI ≥85th but ＜95th percentiles; and very high,BMI ≥95th percentiles.Z-scores based on urban-rural,sex- and age-specific means and standard deviations were calculated,and the sum of Z-scores for the fitness tests was used as a PFI.Differences in PFI between BMI categories were compared with ANOVA.Sex- and grade-specific regressions of PFI on BMI were done by using a linear model.Results For 8941 students,the PFIs on very low,low,normal,high and very high group were-1.77,-0.91,0.32,-0.17 and -0.54,respectively,and showed an inverted U shape.The normal BMI group students presented the highest PFI.Data from Linear regression analysis revealed that PFI was significantly positively correlated with BMI,while negatively associated with BMI square,which indicated that PFI was the quadratic function of BMI.When BMI was increasing,PFI showed a parabolic curvilinear.Conclusion Relationships between BMI and PFI were parabolic curvilinear among the children and adolescents aged 7 to 18 in Anhui province.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prevalence of common psychosomatic symptoms among Chinese adolescents and the influence on 6 months later suicide and self-injurious behavior.</p><p><b>METHODS</b>Based on the cluster sampling method, the participants who were recruited from 8 cities from 3 areas in China, including Eastern areas (Beijing, Shaoxing and Guangzhou), Middle areas (Ezhou, Harbin and Taiyuan) and Western areas (Guiyang and Chongqing), were administered by multidimensional sub-health questionnaire of adolescents (MSQA) in March 2008. Demographics, life style, psychosomatic symptoms, suicide and self-injurious behavior were also assessed. A total of 17 622 questionnaires were valid at baseline. Six months later, 14 407 questionnaires were eligible for two waves investigation. Analysis of Pearson chi-square and logistic model regression analysis were employed to compare the incidence of psychosomatic symptoms, suicide and self-injurious behaviors among different areas and to explore the possible risk factors of those symptoms and behaviors.</p><p><b>RESULTS</b>At baseline, rates of total common physiological and psychological symptoms were 24.1% (4255/17622) and 30.9% (5447/17622), respectively, with the highest being eating and drinking too much (6.4%, 1130/17622) and hardly feel ease to learn at home (11.8%, 2087/17 622). In males, the rate of common psychological symptoms (30.7%, 2637/8599) was higher than physiological symptoms (24.0%, 2061/8599) (P < 0.05); in females, the rate of common psychological symptoms (31.1%, 2810/9023) was higher than physiological symptoms (24.3%, 2194/9023) (P<0.05). The rate of the common psychosomatic symptoms in senior high school students (46.8%, 2905/6208) were significantly higher than those in middle high school students (37.3%, 2337/6262) and college students (33.2%, 1711/5152) (all P values <0.05). Students from Western areas had the highest incidences of the common physiological and psychological symptoms (30.2%, 1471/4871; 40.6%, 1979/4871), higher than students from Middle areas (22.4%, 1443/6453; 27.0%, 1743/6453) and Eastern areas (21.3%, 1341/6298; 27.4%, 1725/6298) (all P values <0. 05). Results from multiple logistic regression showed that physical symptoms > or = 2 at baseline were shared risk factors for suicidal ideation (RR = 1.44, 95% CI:1.16 - 1.79), attempted suicide (RR = 1.79, 95% CI: 1.22 - 2.61) and self-injurious behaviors (RR = 1.39, 95% CI: 1.17 - 1.66) 6 months later. Psychopathological symptoms > or = 4 at baseline was the shared risk factors for suicide ideation (RR = 1.74, 95% CI: 1.39 -2.17), attempted suicide (RR = 2.08, 95%CI: 1.39 - 3.11) and self-injurious (RR = 1.90, 95%CI: 1.59 - 2.28) 6 months later.</p><p><b>CONCLUSION</b>It is common in Chinese adolescents who have multiple psychosomatic symptoms simultaneously. What's important is that those common psychosomatic symptoms are shared risk factors of later suicidal and self-injurious behaviors.</p>

Objective To examine the association between self-assessed somatotypes and depression related symptoms.Methods The study sample included 5555 students aged 9 to 18 years who had attended the Physical Fitness and Health Surveillance of Chinese School Students(2010)in Chizhou city,Anhui province.Association between self-assessed somatotypes,body mass index(BMI)and depression symptom were examined.Results There was a slight consistency between self-assessed somatotypes and BMI in both boys and girls(Kappa=0.217,P=0.000; Kappa=0.203,P=0.000).Significant difference in the prevalence of depression was found among weight misperception groups in both genders(x2=145.223,P=0.000).The prevalence of umderestimation of somatotypes was significantly higher in boys than in girls,while the result was reversive on the prevalence of overestimation.Additionally,the prevalence of depression was higher in girls than in boys(x2=5.199,P=0.023).Through logistic regression,data showed that self-assessed somatotypes and miscalculated groups were significantly associated with depressive symptoms.Compared to the group that self-assessment as being normal,those students when self-assessed as being slim,overweight or obesity were more likely to be depressive,with odds ratio(ORs)as 1.255(95％CI:1.066-1.478),1.538(95％CI:1.275-1.856)and 1.713(95％ CI:1.035-2.834),respectively.Overestimated and underestimated somatotypes appeared to be risk factors causing symptoms of depression(OR=1.705,95％CI:1.382-2.105; OR=1.241,95％CI:1.059-1.454).Conclusion Slight consistency was found between self-assessed somatotypes and BMI,while the misjudged somatotypes were the risk factor related to depressive symptoms.It was suggested that life skills education should be carried out as preventive intervention approach,to improve the physical and mental health well-being of children and adolescents.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression of indoleamine 2, 3-dioxygenase (IDO) in breast cancer and its correlation with clinicopathologic factors and prognosis.</p><p><b>METHODS</b>The expression of IDO, CD31, CD105 proteins in 40 specimens of breast cancer were assessed by immunohistochemistry.</p><p><b>RESULTS</b>The overexpression rate of IDO in breast cancer was 67.5% (27/40), and expression of IDO was closely associated with clinical stage and lymph nodes metastasis. The disease-free survival rate in patients with IDO overexpression was not significantly lower than that in patients with negative or low expression of IDO (P > 0.05). Moreover, the expression of IDO was positively correlated with CD105-labeled microvessel density (r = 0.659, P < 0.05).</p><p><b>CONCLUSIONS</b>Expression of IDO is associated with clinical stage and lymph nodes metastasis, and microvessel densitty. IDO expression may promote the growth and metastasis of breast cancer, probably via the increased agiogenesis. A larger sample study is needed to verify whether the prognosis of beast cancer is significantly correlated with IDO expression.</p>

Objective To investigate the prevalence of love affairs and intimate partner violence,and to explore the relationship between intimate partner violence and other mental health and risk behavior in college students.Methods Three universities were selected using cluster sampling method in Hefei and Wuhu.Totally.2575 college students completed an anonymous questionnaire.Intimate partner violence,depression,satisfaction of school life,self-esteem,suicidal psychology and behavior were evaluated to estimate the relationship between intimate partner violence and mental health/risk behavior.Results There were 46.9%students reported that they had intimate partner currently or in the past.The rate of having intimate partner in male students was higher than that in female students(x2=44.13,P<0.001).And the rates were higher in sophomores and juniors than in freshmen(x2=161.84,P<0.05).There were 21.1% students had sexual behavior with their intimate partners.But only 21.8%(34/156)intimate partners reported that they used condom every time.There were 11.5%(18/156)intimate partners reported that they never took any contraception.There were 18.6%(29/156)students reported that they were pregnant or led to their girlfriend becoming pregnant,but only less than 50.0% adolescents induced abortion in a legal hospitals.The rates of being the victim of physical assault,emotional abuse,sexual coercion,the total intimate partner violence were 18.0%,33.6%,5.1%.37.1%.The rates of being the victim of physical assault,emotional abuse,total intimate partner violence in male adolescents were higher than those in female adolescents,but the rate of sexual coercion was on the contrary(x2=70.21,13.25,14.04,5.77,P<0.05).Among the intimate partners who had suffered from intimate partner,74.2%(345/446)students had underwent more than 3 times.and 47.1% had underwent more than 2 types of intimate partner violence.The score of depression was highest in the victims of intimate partner violence,but the scores of self-esteem and school life satisfaction were on the contrary(F=4.00,16.39,8.76,P<0.05).The rates of suicidal ideation,suicidal plan,suicidal preparative and attempted suicide were highest in the victims of intimate partner violence(x2=13.80,9.72,8.52,11.96,P<0.05).Conclusion The rate of having sexual behavior with their intimate partners was high in college students,but their self-protection awareness was insufficient.In the present study,a high prevalence of intimate partner violence among university students was observed,and highlighted a need for attention to the other mental health and risk behavior in adolescents with intimate partner violence.
ABSTRACT
Objective To investigate the prevalence and influencing factors related to abuse and negligence against the elderly in the rural areas. Methods 975 elderly over 60 years from 41counties in Anhui province were included. All participants completed an anonymous questionnaire including items as: educational background, marital condition, income, child-discipline, rude action to parents, daily activities, physical functions, having chronic illness, abuse and negligence against the elderly, etc. Results In the last year, rates of common physical abuse, serious physical abuse,emotional abuse, financial exploitation, negligence, overall abuse and negligence against the elderly were 4.5%, 1.5%, 26.9%, 4.9%, 7.2%, 29.9% respectively. Among the 281 victims, 80.4% reported that they were suffered more than 3 times of abuse and neglect episodes, and 34.9% reported that they were suffered more than 2 forms of abuse and negligence. The primary sadism was carried out by the daughter-in-law or son-in-law (43.2%) of the elderly. Low activity on daily life and having chronic illness were the risk factors causing common physical abuse while better education was the protective factor to it, Low ability in managing daily activity of living was the risk factor causing serions physical abuse. Less active on daily life and having rude action to parents were the risk factors to emotional abuse, but being strict with their children was the protective factor to emotional abuse. Less active on daily life, often beating their children and having rude action to parents were the risk factors related to financial exploitation. Less active on daily life, having rude action to parents and having bad physical functions were the risk factors causing negligence. Less active on daily life and having rude manner to parents were the risk factors of overall elderly abuse and negligence, but being strict with their children was protective factor to the abuse and negligence against the elderly. Conclusion High prevalence on abuse and negligence against the elderly was seen in the rural areas of China. Different forms on elderly abuse and negligence were affected by different factors that called for more attention to be paid to those elderly with lower ability in managing their daily life.
ABSTRACT
Objective This paper aimed to report the rate of suicide attempts among adolescent and young students of eight cities in China, and to examine the impact of related psychosocial factors on suicide attempts. Methods The investigation was obtained in senior and junior high school and college students in eight cities of China. All of the 17 622 participants were recruited to complete anonymous questionnaires regarding their experiences of suicide attempts and related psychosocial factors. Results Overall, 2.2 percent of the respondents reported that they had experienced attempted suicide during the previous year. Scores on high anxiety (OR=2.61,95%CI: 1.64-4.16),high depression (OR=2.05, 95%CI: 1.35-3.10),suicide idea (OR= 14.21, 95%CI: 9.88-20.43),suicide plan(OR=3.50,95%CI:2.59-4.73) were revealed as common risk factors while the whole time span being accompanied by mothers during juvenile years (OR=0.38, 95% CI: 0.20-0.74) seemed to be protective factor for suicide attempts through multivariate logistic regression analysis. Conclusion Our results showed that emotional symptom, idea and plans for suicide were statistically associated with suicide attempted in high school and college students.
ABSTRACT
<p><b>BACKGROUND</b>S100A8 and S100A9 are two members of the S100 protein family characterized by the presence of two Ca2+-binding sites of the EF-hand type. Previous studies suggested that the whole S100 family displays significant functions in tumor growth, progression and invasion. This study aimed to determine the expression of the two indices of the family, S100A8 and S100A9, in lung cancer tissues and normal lung tissues and its correlation with clinical features.</p><p><b>METHODS</b>A total of 60 cases with a variety of clinical data that were diagnosed with different histological subtypes of lung cancer were investigated. Semi-quantitative reverse transcriptase-PCR (Sq-Rt-PCR) and immunohistochemical staining of cancer, adjacent and peripheral lung tissues were executed to distinguish the expression patterns of S100A8 and S100A9 and to further clarify their correlation with clinical features.</p><p><b>RESULTS</b>Immunohistochemical staining of both proteins showed a significant up-regulation in lung cancer tissue (S100A8, S100A9, P<0.0001), and PCR revealed that the levels of S100A8 and S100A9 expression were significantly higher in lung cancer tissues (S100A8 P=0.002/0.004; S100A9 P=0.022/0.026). The higher expression was found to be correlated with the clinical characteristics of adenocarcinoma, inflammation and stage IV lesion.</p><p><b>CONCLUSIONS</b>S100A8, S100A9 up-regulation was found in the lung adenocarcinoma and end stage lung cancer tissue, the correlation of which with their higher expression in inflammatory lung tissues may indicate the collaborative effect of inflammation on the progression of cancer.</p>
