Nerve agent not only inhibit acetylcholinesterase ( AChE) at an early stage, but also induce prolonged and progressive neuroinflammation and delayed neurodegeneration.Recently, the US National Institute of Health ( NIH) has sponsored some major programs of toxic mechanisms and treatment of nerve agents, which aims at the development of quick and effective treatment to acute intoxication and delayed effect.The experimentally effective new antidotes mainly include AChE-targeting drugs, broad-spectrum reactivators and scavengers, antiinflamatory and nerve protection drugs.

Purpose To detect the incidence rate, average age and the expression of hMLH-1 and hMSH-2 of sporadic colorectal carci-noma ( SCC) with Han and Uygur patients. Methods The expression of hMLH-1 and hMSH-2 was detected in SCC for 60 cases of Uygur and 196 cases of Han by immunohistochemical method, including 60 Uygur and Han cases normal colorectal mucosa ( NCM) . Results The positive rate of hMLH-1 and hMSH-2 proteins expression in the NCM was 100%. There was a marked difference in the positive rate of hMLH-1 in SCC between Han (93. 4%, 183/196)and Uygur (75%, 45/60) (P<0. 05). There was no significance in the positive rate of hMSH-2 in NCM between Han (94. 4%, 185/196) and Uygur (91. 7%, 55/60) (P>0. 05). The average age of Han and Uygur SCC patients were 65. 64 years, 57. 63 years, respectively, and Uygur SCC cases were more likely to be diagnosed at less 40 years old (P<0. 05). The positive rate of hMLH-1 and hMSH-2 expression in the tubular adenoma was 100%. The positive rate of hMLH-1 and hMSH-2 expression in the tubulovillous adenoma in Uygur and Han were 66. 7%( 2/3 ) and 66. 7%( 2/3 ) , and 74. 2%(23/31) and 90. 3%(28/31), respectively, significantly lower than those of tubular adenoma (P<0. 05). The expression of hMLH-1 was positively correlated with that of hMSH-2 in SCC in Han(rs =0. 737, P<0. 05). The expression of hMLH-1 was positive-ly correlated with that of hMSH-2 in SCC in Uygur(rs =0. 383, P<0. 05). There exists marked difference in the positive rate of hM-LH-1 and hMSH-2 among difference age groups (P<0. 05). Conclusion There is a certain loss of hMLH-1 and hMSH-2 expression in SCC in Han and Uygur Chinese, which is related to adenoma and age. The expression of hMLH-1 in SCC tissue among Uygur pa-tients is not resemble to those of Han patients. The average age of Uygur SCC patients is younger than Han, and the positive rate of hMLH-1 is higher. Combined detection of hMLH-1 and hMSH-2 proteins may be used for judging the severity and prognosis of SCC in Xinjiang, which helps improve patients’ treatment program and rationalize their choices.

BACKGROUND:Stroke is the leading cause of death and long-term disability. This study was undertaken to investigate the factors influencing daily activities of patients with cerebral infarction so as to take interventional measures earlier to improve their daily activities. METHODS:A total of 149 patients with first-episode cerebral infarction were recruited into this prospective study. They were admitted to the Encephalopathy Center, Department of Neurology, the First Affiliated Hospital of Wenzhou Medical College in Zhejiang Province from August 2008 to December 2008. The baseline characteristics of the patients and cerebral infarction risk factors on the first day of admission were recorded. White blood cell (WBC) count, plasma glucose (PG), and many others of laboratory targets were col ected in the next morning. Barthel index (BI) was calculated at 2 weeks and 3 months respectively after onset of the disease at the outpatient clinic or by telephone cal . Lung infection, urinary tract infection and atrial fibrillation if any were recorded on admission. The National Institute of Health Stroke Scale (NIHSS) scores and the GCS scores were recorded within 24 hours on and after admission, at the second week, and at the third month after the onset of cerebral infarction respectively. RESULTS:The factors of BI at 2 weeks and 3 months after onset were the initial PG level, WBC count and initial NIHSS scores. Besides, urinary tract infection on admission was also the factor for BI at 3 months. CONCLUSION:Active measures should be taken to control these factors to improve the daily activities of patients with cerebral infarction.
