Objective To observe the effects of Fuyanshu Capsule on phenol mucilage-induced endometritis rats and the possible anti-inflammation mechanism of the therapeutic effects.Methods Chronic endometritis in rats was induced by injection of phenol mucilage suspension into the uterus.Sixty female SD rats were randomly divided into 6 groups,namely,sham-operation group (distilled water,10mL/kg),model group,Jinji capsule group (0.65 g/kg),and Fuyanshu Capsule groups (1.8 g/kg,0.9 g/kg and 0.45 g/kg).After the rats were treated 28 days with corresponding medicine by intragastric administration,the pathology of the endometrium and changes of tumor necrosis factor α(TNF-α)and interleukin-2 (IL-2)levels were detected to evaluate the effects of Fuyanshu Capsule. Results Fuyanshu Capsule (1.8 g/kg and 0.9 g/kg)ameliorated the body weight reduction caused by endometritis in rats.Fuyanshu Capsule (1.8 g/kg,0.9 g/kg and 0.45 g/kg)reduced the ratio of the swelling uterus and ovaries to body weight of the rats.It ameliorated obviously the hyperplasia,necrosis and degeneration of endometrial epithelia and infiltration of inflammatory cells.The capsule (1.8 g/kg)decreased the serum IL-2 level in the rats with phenol mucilage-induced endometritis. Conclusion The anti-inflammatory effect of Fuyanshu Capsule on chronic endometritis induced by phenol mucilage in rats may be related to the decrease of IL-2 level.

Objective To investigate the episodes and influencing factors on self-harm and to explore the relationship between self-harm episodes and suicidal psychology and behaviors in college students. Methods Four universities were selected using cluster sampling method in Anqing city and Chaohu city. Totally, 2713 college students completed this survey. Data were analyzed by Pearson Chi-square and logistic regression. Results In the last six months, rates of highly lethal self-harm,less lethal self-harm with visible tissue damage, self-injury without visible tissue damage,self-harmful behaviors with latency damage, other self-harmful behaviors with menticide were 1.9%,5.5%, 15.3%, 21.2% and 17.0% respectively. The total rate of self-harm was 31.3%. 73.1% of the students with self harmful experiences had the above mentioned behaviors more than 3 times in the last six months. The top 3 reasons for taking self-harm actions were: having learning problems (43. 1% ), failed love affairs (25.0%) and having conflicts with others (23.9%). There were different influencing factors among different kinds of self-harm episodes. Depression was the risk factor of self-harm. The higher score of having high self-esteem was the protective factor of all kinds of self-harm actions except highly lethal ones. Higher score of difficulties in identifying feelings was one of the risk factors. The rates of suicidal psychology and behaviors in students with self-harm were significantly higher than those in students without those behaviors. Result from linear x2 test indicated that the graveness of tissue damage of self-harm was higher along with the rates of suicidal psychology and behaviors (P＜0.01). Conclusion Among 2713 college students, about 1/3adolescents having experienced self-harm in the last 6 months, many with repeated ones. Depression and difficulties in identifying feelings were the two risk factors while self-esteem was the protective factor related to most of the self-harm cases.

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.

BACKGROUND:Abnormal activation of lymphocytes and nuclear factorκB-dependent non-specific inflammation are two major manifestations of joint damage in rheumatoid arthritis. Co-stimulatory signal CD40/CD40L is the dominant co-stimulatory factor in the recognition and activation of T cel s. IκBαeffectively inhibits nuclear factorκB pathway, prevent the inflammation in the central link, and suppress the damage caused by inflammatory factor in the synovial tissue.
OBJECTIVE:To investigate the therapeutic effect of double gene co-expressing adenovirus vector on arthritis based on an arthritis model rat transfected by CD40LIg-IRES2-IκBαco-expressing adenovirus vector.
METHODS:The pAdCD40LIg-IRES2-IκBαco-expressing adenovirus vector was established. Arthritic model was established through multi-subcutaneous injections of complete Freund's adjuvant of type col agen II (1 g/L) into Wistar rats. Then 20 arthritic rats were divided into two groups:untreated group and transfection group, receiving an injection of saline and pAdCD40LIg-IRES2-IκBαadenovirus vector to distal joint cavity of limbs, respectively.
RESULTS AND CONCLUSION:At 14 days post-transfection, compared with the untreated group, the mean arthritis index score, the CD40L expression of lymphocytes in synovial fluid, the nuclear factor-κB p65 expression in synovial tissue, and levels of interleukin-2, interleukin-6, tumor necrosis factor-α, matrix metal oproteinase-3 and matrix metal oproteinase-9 in synovial fluid of rats in transfection group were significantly lower than those in untreated group. Focal transfection of the CD40LIg-IκBαco-expression adenovirus vector can effectively inhibit arthritic symptoms, and reduce the expressions of inflammatory cytokine in synovial fluid and inflammatory molecule in synovial tissue of arthritic rats, which shows good therapeutic effect.

Objective This study was undertaken to examine possible relationship between attempted suicide and underachievement,bullying,low life satisfaction and low self-concept at school.Methods An anonymous self-report survey assessing demographic characteristics and the major risk factors of teenage attempted suicide was completed by students from 16 middle schools in grades seven to twelve in 4 counties of Anhui province (age 10 to 21 years).An anonymous questionnaire was used to rate attempted suicide,bullying involvement and learning performance.Attempted suicide was defined as: experiencing specific suicide actions at least one time during the 12 months preceding the survey.Multidimensional Students' Life Satisfaction Scale and Children' s Self-concept Scale were used to evaluate satisfaction and self-conscience on and at respectively.In total,10 894 respondents substantially completed the survey.Multiple logistic-regression analyses,controlling for socio-demographic variables,was used to analyze if underachievement,bullying,low school life satisfaction and low children' s self-conscience at school had been risk factors.Results 629 participants (5.8%) reported having made at least one attempted suicide within the last 12 months.Students being underachieved were significantly having more attempted suicide events than those excellent students (X2=11.39,P=0.023).Students being both bully-victims and practiced bully were significantly more than those being only practiced bully (28.7% vs.15.8%,P＜0.001),being victims (28.7% vs.10.6%,P＜0.001) or having neither of them (28.7% vs.4.8%,P＜0.001).Results from multiple logistic regression analyses showed that underachievement,bullying,lower school life satisfaction and low self-conscience were risk factors for attempted suicide.Conclusion Data from this study confirmed that school bullying and children' s self-conscience at school were significantly associated with attempted suicide among rural middle school students in Anhui province.It is of importance to improve the school' s environments to reduce the risk of attempted suicide among this group.

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.

Objective To evaluate the predictive values of serum neutrophil gelatinase-associated lipocalin (NGAL), urine NGAL, serum cystatin C (Cys-C) and serum creatinine (Scr) for early delayed graft function (DGF) in kidney transplant recipients. Methods Clinical data, blood and urine samples of 159 kidney transplant recipients were collected. All recipients were divided into the DGF group (n=42) and immediate graft function (IGF) group (n=117) according to the incidence of DGF. Clinical data of all recipients were analyzed. The changes of serum NGAL, urine NGAL, Cys-C and Scr levels were statistically compared between two groups. The predictive values of different markers for early DGF were assessed. Results Among 159 kidney transplant recipients, DGF occurred in 42 cases with an incidence rate of 26.4%. There were statistically significant differences in donor age, cold ischemia time of donor kidney and complement-dependent cytoxicity (CDC) between the two groups(all P < 0.05). Within postoperative 2 weeks, the serum NGAL levels in the DGF group were higher than those in the IGF group (all P < 0.05). The Cys-C, Scr and urine NGAL levels in the DGF group were higher compared with those in the IGF group within 3 weeks after kidney transplantation(all P < 0.001). Serum NGAL, urine NGAL, Cys-C and Scr levels had certain predictive values for early DGF in kidney transplant recipients. Cys-C yielded the highest predictive value with a cut-off value of 4.73 mg/L, sensitivity of 0.833, specificity of 0.812 and area under the curve (AUC) of 0.895. Conclusions Cys-C has higher predictive value for early DGF in kidney transplant recipients compared with serum NGAL, urine NGAL and Scr.

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.

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.

Objective:To investigate the frequency of myeloid dendritic cells (mDC) and plasmacytoid dendritic cells (pDC) in peripheral blood of patients with systemic lupus erythematosus (SLE) and their relationship with renal injury.Methods:The frequency of peripheral mDC and pDC in 102 SLE patients and 10 healthy controls were detected by flow cytometry. The quantitative data were expressed by [ M( P25, P75)]. The measurement data of the two groups with non-normal distribution was analyzed by Mann Whitney U test. The correlation between the two groups was analyzed by Spearman rank correlation analysis and multiple linear regression. Results:The frequency of pDC [14.00%(7.92%, 19.65%) vs 24.55%(19.68%, 32.90%), Z=-3.163, P<0.01] and mDC [21.25%(13.28%, 32.83%) vs 34.85%(24.58%, 41.93%), Z=-2.607, P<0.01] in the peripheral blood of 102 patients with SLE were significantly lower than those of healthy controls. The frequency of pDC [9.09%(7.31%, 17.38%) vs 24.55%(19.68%, 32.90%), Z=-3.033, P=<0.01] and mDC [9.40%(7.88%, 21.60%) vs 34.85%(24.58%, 41.93%), Z=-3.231, P<0.01] in 12 patients with newly diagnosed SLE were also significantly lower than those in healthy controls. After adjustedfor confounding factors, multivariate analysis showed that SLEDAI level was the main factor influencing the frequency of pDC ( P=0.019) and mDC ( P<0.01). In addition, pDC[8.02%(2.25%, 9.97%) vs 16.70%(11.80%, 24.60%), Z=-2.490, P=0.015] and mDC[8.80%(5.99%, 12.80%) vs 20.20%(11.20%, 42.80%), Z=-2.226, P=0.029] in patients with active LN were also significantly lower than that of patients with stable LN. The mDC frequency was positively correlated with the levels of complement C3 ( r=0.455, P<0.01) and C4 ( r= 0.289, P, P<0.01). Conclusion:The frequency of mDC and pDC in SLE patients is significantly abnormal, which is closely related to disease activity. In addition, pDC and mDC may be involved in the occurrence and development of LN.
