Factors Influencing the Initiation Time of Forensic Psychiatric Assessment of Criminal Cases in Hunan Province / 法医学杂志

Objective To discuss the related factors influencing the initiation time of forensic psychiatric assessment by analysis of the initiation time of forensic psychiatric assessment of criminal cases in Hunan Province. Methods Related data in assessment files of criminal cases accepted by 8 forensic psychiatric assessment institutions in Hunan Province from January 1, 2011 to December 31, 2016 were extracted. The Logistic regression analysis was used to explore the factors influencing the initiation time of forensic psychiatric assessment. After using property score matching （PSM） to control the influence of confounding factors, the efficiency of public security organs to initiate assessments of suspects with （without） mental disorders and with （without） responsibilities were compared. Results A total of 4 346 cases were included. The Logistic regression analysis suggested that the factors independently related to the initiation time of assessment include： cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime （all P<0.05）. The initiation time of assessment of suspects diagnosed with mental disorder was shorter than those with none （P<0.05）; the initiation time of assessment of suspects without criminal responsibility was shorter than those with responsibility （P<0.05）. After using PSM to control confounding factors, the differences above still existed. Conclusion The cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime are factors that influence the efficiency of public security organs to initiate forensic psychiatric assessments. Under the current assessment initiation mode, forensic psychiatric assessment of suspects who have mental disorders, especially those with no responsibility may be given priority to initiate.

Prognostic factors affecting survival of 211 cervical adenocarcinoma patients / 预防医学

Objective This study was conducted to determine the prognostic factors of cervical adenocarcinoma.Methods Between July 2008 and June 2013, 211 consecutive patients were treated because of International Federation of Gynecology and Obstetrics(FIGO) stage IA-IVB cervical adenocarcinoma.Overall survival was analyzed by the Kaplan-Meier method.Results One-year OS rate was 96.2%,and 3-year OS rate was 88.6%,and 5-year OS rate was 74.7%.Patients'age,FIGO stage,postoperative clinicopathological factors such as depth of stromal invasion,number of pelvic lymph node metastasis and para-aortic lymph node metastasis,were analyzed to discriminate their prognostic role.In the univariate analysis, age,FIGO stge,deep stromal invasion, lymph-vascular space invasion, number of pelvic lymph node metastasis,para-aortic lymph node metastasis were associated with poorer survival(P< 0.05).In the cox analysis, age (RR=4.940,95%CI:1.925-12.678),pelvic lymph node metastasis(RR=2.391,95%CI:1.311-4.360),para-aortic lymph node metastasis (RR=6.344,95%CI:1.007-39.990)and FIGO stage(Ⅲ vs I,RR=5.315,95%CI:2.760-12.203;Ⅳ vs I,RR=9.932,95%CI:2.905-18.846)were independent prognostic factors of invasive cervical adenocarcinoma.Conclusion Early detection and early treatment is very important for cervical adenocarcinoma patients.Give the patient suitable and maybe more aggressive adjuvant therapy according to surgical pathology is helpful for imporving adenocarcinoma treatment.

Comparison of major bioactive components from leaves of Chrysanthemum morifolium / 中国中药杂志

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

The influence of smoking on the routine parameters of semen quality / 中华流行病学杂志

Objective To explore the effect and heaviness of smoking on the routine parameters of semen quality.Methods A total of 727 eligible subjects including 421 smokers and 306 nonsmokers were selected in 2004-2006 in Hebei,Shanxi,Guizhou,Zhejiang and Shandong provinces.Data on background information,general demographic characteristics,exposure to smoking and related confounding factors were obtained through a questionnaire survey.Semen samples of all the subjects were collected during the period of study.Parameters of semen were examined according to the manual recommended by WHO.Results Four models from the multiple logistic regression regarding the semen routine parameters were used as the dependent variables to be fitted in descending order respectively,while six confounders including area,age,abstinence time,education level,history of alcohol intake and the exposure to pesticides atc.,were adjusted.Results showed that smoking could affect the sperm viability,with significantly higher proportion of abnormal sperm viability seen in the smoking group (OR= 1.77,95％ CI:1.12-2.80).Proportions regarding the abnormal mobility and morphology of sperms in the smoking group were also significantly higher than in the control group,with OR values as 1.51 (95％CI:1.00-2.27) and 2.55 (95％CI:1.68-3.88) respectively.The density of sperms was significantly decreased in the smoking groups who smoked more than 20 cigarettes per day (OR= 1.70,95％CI:1.05-2.76) or the total numbers of cigarette consumption exceeding 150 000(OR=1.84,95％CI:1.03-3.29).Conclusion Smoking showed adverse effects on the quality of semens,especially for heavy or long-term smokers.

Effects of valsartan on renal interstitium fibrosis in rats after unilateral ureteral obstruction / 第二军医大学学报

Objective To study the effect of valsartan, an angiotensin II type I receptor antagonist AT1RA), on renal interstitium fibrosis(RIF)in rats with unilateral ureteral obstruction (UUO), and to discuss the possible mechanisms. Methods Thirty-five Sprague-Dawley rats were randomly divided into sham-operation, model and valsartan groups. The rat UUO model was established. From the day after operation, the rats in sham-operation and model groups received intragastric valsartan and sodium chloride in tales doses. The serum creatinine (SCr), blood urea nitrogen (BUN), angiotensin- II (Ang II ) in blood plasma, N-acetyl-β-D-glucosaminidase(NAG)and 24 h urine β2-microglobulin(β2-MG)were examined 4 weeks after operation. The renal tissues of the obstructed sides were harvested; H-E staining and Masson staining were used to observe the tubulointerstitial lesions; and immunohistochemistry staining was used for semiquantitative analysis of alpha-smooth muscle actin(α-SMA), fibronectin(FN), plasminogen activator inhibitor-1 (PAI-1), transforming growth factor-beta 1 (TGF-β1), and hepatocyte growth factor(HGF). Results Compared with those in the sham-operation group, SCr, BUN, Ang II, NAG and (β2- MG levels, and the expression of α-SMA, FN, PAI-l, and TGF-β1 in model group were significantly higher(P0. 05). The expression levels of orSMA, FN, PAI-l, and TGF-β1 in valsartan group were significantly lower than and the expression of HGF was significantly higher than those in the model group(P<0. 01). Conclusion Valsartan does not improve the tubular and glomerular functions, but it can inhibit production of Ang-II. Valsartan may inhibit renal interstitial fibrosis by inhibiting renal tubule epithelial mesenchymal transdifferentiation and reducing extracellular matrix deposition through blocking up Ang Q, inhibiting overexpression of α-SMA, FN, PAI-l, and TGF-β1, and inducing the HGF expression.

Effect of 5-HT and postsynaptic 5-HT1 A on the mood and recogniztion of the repeated restraint stress in rats / 中南大学学报(医学版)

OBJECTIVE@#To explore the role of 5-HT and postsynaptic 5-HT1A receptors in the stress adaptation.@*METHODS@#p-PCA was used to deplete the 5-HT in rats. The 5-HT1A agonist 8-OH-DPAT and antagonist WAY100635 were used to determine the effect of postsynaptic 5-HT1A receptors on the ratso behaviors in the Elevated Plus-Maze test, the Forced Swimming test, and the Morris Water Maze test.@*RESULTS@#Compared with the intact rats, the 5-HT depleted rats showed more seriously anxious behaviors in the Elevated Plus-Maze test and more obvious learned helplessness in the Forced Swimming test. After having been stressed the 5-HT depleted rats showed significantly impaired learning and memory compared with the intact rats according to Morris Water Maze test. Activation of postsynaptic 5-HT1A receptors by 8-OH-DPAT in the 5-HT depleted rats or the 5-HT depleted stress rats significantly decreased the symptoms of anxiety and learned helplessness behaviors which were prevented by the treatment of WAY100635. The 8-OH-DPAT and WAY100635 had no obvious effect on the 5-HT depletion or 5-HT depleted stress rats in the Morris Water Maze test.@*CONCLUSION@#Deficiency of 5-HT in rats may suppress its ability to stress adaptation. Activation of post-synaptic 5-HT1A receptors can attenuate the anxiety and depressive behavior symptoms, and facilitate rats to adapt stress.
