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.

Objective To observe the relationship of awake bispectral index (BISawake) and the postoperative cognitive dysfunction (POCD). Methods 100 patients aged 60~75 years with ASA status Ⅰ~Ⅱ, underwent elective lower abdominal surgery with intravenous anesthesia (propofol, remifentanyl and rocuronium). The BIS was adjusted in 40~60 during the surgery. Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction (ISPOCD). Results 8 patients withdrew for unwilling or serious complications. The BISawake was more than 65 in 68 patients (group A), and less than 65 in 24 patients (group B). The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A. Conclusion Lower BISawake may be associated with the decline of postoperative cognitive function.

Objective To explore the significance of 1.5-Tesla MRI in the early diagnosis of prostate cancer,and analyze the imaging features in T2WI which are helpful for the diagnosis on early prostate cancer.Methods The clinical data of patients with PSA < 20 μg/L who received prostate biopsy between Feb.2006 and Jan.2011 were reviewed including pelvic MRI and biopsy results.We retrospectively analyzed T2WI image features and evaluated the signal of peripheral zone,seminal vesicles,prostate capsule and the relationship with their surrounding tissues.The results of the reading were analyzed with reference to histopathologic evaluation of prostate biopies.Results Among 359 patients,137 patients were diagnosed prostate cancer and 332 cases were found with low signal lesions on peripheral zone of T2WI.Univariate logistic regression analysis showed that age and PSA are closely related to the diagnosis of prostate cancer (P < 0.05).Low signal lesions on peripheral zone of T2WI are more helpful for the diagnosis of prostate cancer on the image.Number,shape,margin of lesions,the contour of the prostatic capsule,the boundary of peripheral zone and transitional zone are significantly associated with the diagnosis of prostate cancer.Through multivariate logistic regression analysis,it was found that age (P < 0.05),PSA (P < 0.05),prostate volume (P < 0.05),lesion shape (flaky vs nodular,P < 0.05 ; diffuse vs nodular,P < 0.05) and the contour of the prostatic capsule (disappearing vs completely clear,P < 0.05) are risk factors of prostate cancer.The areas under receiver operating characteristic curve are 0.833 (P < 0.05).Conclusions In T2WI,lesion shape and the contour of the prostatic capsule are risk factors of prostate cancer.Age,PSA,prostate volume are also significantly associated with the diagnosis of prostate cancer.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.
