Objective To analyze the features of drowning victim s with psychiatric disorders to support further investigation on such cases. Methods O ne hundred and five archives of drowning victim s with psychiatric disorders from January 2010 to June 2014 in H arbor Public Security Subbureau, Shanghai Public Security B ureau were reviewed. The decedents’ general inform ation, autopsy findings, case inves-tigation data and disease histories were statistically analyzed. Results O f the 105 cases, 104 were sui-cides. Most decedents were poorly educated. Most suicides occurred in warm clim ate, and the corpses were usually found within 2 days. Most decedents had no suicide history and notes, but had abnorm al m ental or behavior changes before suicide. D epression, depression status and schizophrenia were the m ain types of psychiatric disorders, and only 9 decedents had received regular therapies before their deaths. Conclusion Mental disorder is a high risk factor in the drowning victim s. G uardians should be aware of psychotic abnorm al behaviors, especially during warm clim ate seasons.

OBJECTIVE:
To analyze the case characteristics of poisoning by exhaust gas of the imperfect combustion of natural gas and provide references for forensic identification and prevention of such accidents.
METHODS:
Twenty-two cases of poisoning by exhaust gas of the imperfect combustion of natural gas in Minhang District during 2004 to 2013 were collected. Some aspects such as general conditions of deaths, incidence time, weather, field investigation, and autopsy were retrospectively analyzed.
RESULTS:
In the 22 cases, there were 15 males and 16 females. The age range was between 2 and 82 years old. The major occurring time was in January or February (8 cases in each) and the cases almost occurred in small area room (21 cases). There was wide crack next to the exhaust port when the gas water heater was been used in all cases.
CONCLUSION
There are more prone to occurrence of exhaust gas poisoning of imperfect combustion of natural gas in small area room with a ventilation window near the exhaust port of gas water heated. It shows that the scene of combustion exhaust gas poisoning should be more concerned in the cold season.

0.05),which were (5.64?2.00)d in single-circle group,(5.80?3.74)d in double-circle group,(6.22?2.76)d in triple-circle group.According to the treatment effects,CEA value decreased during pre-and post-neoadjuvant chemotherapy in each groups(P0.05).Through our survey,used different neoadjuvant chemotherapy circle,patients in single-circle group and double-circle group were completely accepted within full confidence;but receptance of strategy in triple-circle group was 66.7 %(12/18).All operations were suc- cessful.The difference of postoperative aerofluxus time between single-circle group and double-circle group had sta- tistical significance(P0.05).Conclusion Analyzing neoadjuvant chemo- therapy circles,time between neoadjuvant chemotherapy and operation,treatment effect and operation results,it is a feasible and secure colorectal cancer multi-discipinary strategy for patients in West China that choose the treatment of neoadjuvant chemotherapy with double-circle and short preparation time.

1000 IU/L,TBil 40~250 mg/L,and mild liver dysfunction at beginning of the disease,but acute severe hepatic lesion occurred due to the use of antibiotics,immunodepressant or NSAIDs.Three patients developed liver function failure and died,7 patients' liver function recovered to nor- mal by increasing dosage of glucocorticoid.Conclusion AOSD with mild liver dysfunction is frequently en- countered.During the treatment,acute severe hepatic lesion may occur due to certain drugs.Therefore,any drug used in AOSD with mild liver dysfunction should be cautious.Once acute severe hepatic lesion happens, increases the dosage of glucocorticoid promptly can improve prognosis.

Objective To study the changes of gastrointestinal movement function in rats with chronic unpredictable mild stress(CUMS) and explore the mechanisms underlying it.Methods The rats were divided into stress model group and control group.The stress model rats were induced by 21-day chronic unpredictable mild stress as well as social-isolated fed.The rate of ink propulsion of gastrointestinal tract and the contraction of intestinal canal in rats were observed.Immunohistochemistry was adopted to detect the expression of OT in rats.Results (1) After the models were induced,weight-gain and sucrose preference of model group ((69.97 ± 9.81) g,(49.05± 5.98) g) were lower than those in control group ((116.27 ± 13.60) g,(83.51 ± 3.08) g) (P < 0.001),and both the crossing-score and rearing-score ((24.00 ± 13.52),(3.90 ± 2.51)) were lower than those in control group ((53.60 ± 27.98),(11.50 ± 8.85)) in the open-field test.(2) The rate of ink propulsion of model group ((67.33 ± 6.24) %) was decreased when compared to the control group ((76.83 ± 10.00) %) (P < 0.05),and the intestinal canal contraction amplitude and contraction frequency ((1.37 ± 0.18) g,(0.58 ± 0.02) S-1) were lower than those in control group ((1.88 ± 0.13) g),(0.62 ± 0.04) S-1) (P < 0.05).(3) Compared with the control group (6.07 ± 3.71),OT immunoreactive substance was increased in model group (59.17 ± 16.08) of rats (P<0.001).Conclusion Chronic stress can cause the decrease in gastrointestinal movement function of rats.These changes may be related to the increased expression of OT in paraventricular nucleus.

OBJECTIVE:
To analyze the features of drowning victims with psychiatric disorders to support further investigation on such cases.
METHODS:
One hundred and five archives of drowning victims with psychiatric disorders from January 2010 to June 2014 in Harbor Public Security Subbureau, Shanghai Public Security Bureau were reviewed. The decedents' general information, autopsy findings, case investigation data and disease histories were statistically analyzed.
RESULTS:
Of the 105 cases, 104 were suicides. Most decedents were poorly educated. Most suicides occurred in warm climate, and the corpses were usually found within 2 days. Most decedents had no suicide history and notes, but had abnormal mental or behavior changes before suicide. Depression, depression status and schizophrenia were the main types of psychiatric disorders, and only 9 decedents had received regular therapies before their deaths.
CONCLUSION
Mental disorder is a high risk factor in the drowning victims. Guardians should be aware of psychotic abnormal behaviors, especially during warm climate seasons.

BackgroundDiabetic retinopathy (DR) is the result of the cytokine network disorders,the imbalance of angiogenic factor and vascular inhibitory factor is the start factor.ObjectiveTo analyze the levels of CXC chemotatic factors of type 2 diabetes mellitus patients,evaluate the clinical application value of them in different clinical types of DR using receiver operating characteristic (ROC)analysis and to approach the new way of individualized treatment.Methods This was a prospective research.The gold standard was ophthalmolscope and fundus fluorescein angiography.The levels of CXC chemotatic factors and multiplicaiton factors were measured in 96 cases with type 2 diabetes mellitus (66 cases with retinopathy and 30 cases without retinopathy as control).The assessment tasks were performed for these index and courses of DR with ROC curve.Results The expression of age,course of disease has significant difference in different courses of DR ( F =8.507,P =0.001 ; F =28.143,P =0.000).Compared with the control group,the expression of growth-related oncogene-α ( GROα ) ( t =- 2.172,P =0.035,AUC =0.625 ),whole blood viscosity 200 ( t =- 3.724,P =0.001,AUC =0.904 ) and neutrophilic leukocyte (t=-2.562,P =0.013,AUC =0.577 ) has significant difference in the group of mild NPDR.Compared with the control group,the expression of interferon-γ-inducible protein 10 ( IP-10 ) ( t =-3.591,P =0.001,AUC =0.592 ),platelet derivation growth factor-BB ( PDGF-BB ) ( t =- 3.233,P =0.003,AUC =0.735 ),vascular endothelial growth factor(VEGF) ( t =- 3.617,P =0.001,AUC =0.776 ),C peptide ( t =- 3.366,P =0.002,AUC =0.962 ),leukocyte ( t=-3.201,P =0.003,AUC =0.852) and neutrophilic leukocyte(t =-4.201,P=0.000,AUC =0.852) has significant difference in the group of moderate and severe NPDR.ConclusionsCXC chemotatic factors may act as reactivator in the pathogenesis of DR,GROα and IP-10 may be useful for clinical monitoring of the severity of DR,and evaluating the imbalance state of chemotatic factors maybe a new approach to clinical monitoring and prognosis of DR.
