ObjectiveTo analyze the related data of patients with severe pesticide poisoning in Tongling area, put forward the countermeasures,and provide available basis to improve the level of prevention and treatment of the disease.Methods Forty patients with severe pesticide poisoning admitted to the Department of Critical Care Medicine of Tongling People's Hospital Affiliated to Wannan Medical College from August 2014 to November 2015 were analyzed retrospectively, the clinical data including distributions of sex, ages, kinds of poisoning drugs, causes of poisoning, time from intoxication to admission into a hospital, rescue therapy, prognosis etc.Results In the 40 patients, there were 12 males and 28 females, the ratio between male to female was 1∶2.33, and the number of women was significantly higher than that of men. Their ages ranged from 40 - 60 years, accounting for 37.5% (15/40). The toxic agent the most commonly seen was organic phosphorus pesticide (15 cases, accounting for 37.5%), and cases with mixed poisoning by taking two or more than two kinds of toxic material accounted for 25.0% (10/40). In addition, the cause of poisoning was mainly due to family quarrels (33 cases, accounting for 82.5%). In regard of time between taking toxic material to admission into a hospital, only did 3 cases admit into the hospital within 1 hour (7.5%), and the majority was within 3 hours (15 cases, accounting for 37.5%). The comprehensive treatments were as follows: clear means to clear the toxin,solution (to use antidote to detoxify), maintainance (to maintain the basic vital signs) and exclusion (to exclude other complications early); the curative effect of comprehensive treatments was satisfied, and 3 cases died, accounding for 7.5%.Conclusions The majority of patients with severe pesticide poisoning in Tongling city are adult females, the main cause of taking toxic material is due to family quarrels, and the toxic agent the most commonly seen is organic phosphorus pesticide. Directing to the above high risk factors, the prevention and treatment are carried out, anticipating the incidence, mortality and medical cost can be reduced significantly.

Objective To lay the foundation for studying the synthesis of artemisinin in microorganism,squalene synthase(SS) gene,a key enzyme gene from Saccharomyces cerevisiae,was cloned and a yeast expression vector was constructed.Methods After amplification of SS gene by polymerase chain reaction(PCR),ligation to T-vector and analysis of the cloned sequence,enzyme digestion and reconfirmation of the target gene,the antisense yeast expression vector was constructed by inverted insertion of the target gene into a yeast expression vector,pGAPZ?A,and digested with two restriction enzymes for vertifying the recombinant.Results The length of SS gene was 1335bp.The preliminary sequence data indicated that SS gene obtained from the experiment had a high sequence homology with that from GenBank,except for a few base pairs.The antisense yeast expression vector has been constructed and vertified by digesting with two enzymes.Conclusion SS gene from Saccharomyces cerevisiae has been successfully cloned and sequenced.An antisense yeast expression vector has been also constructed.

To explore the relation of angiotensin-converting enzyme (ACE) and angiotensin II type 1 receptor (AT1R) gene polymorphism with coronary heart disease (CHD) and the severity of coronary artery stenosis, 130 CHD patients who underwent coronary angiography were examined for the number of affected coronary vessels (> or = 75% stenosis) and coronary Jeopardy score. The insertion/deletion of ACE gene polymorphism and AT1R gene polymorphism (an A-->C transversion at nucleotide position 1166) were detected by using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) in CHD patients and 90 healthy serving as controls. The results showed that DD genotype and of ACE were more frequent in CHD patients than that in control group (38.5% vs 14.4%, P<0.001). The frequency of the AT1R A/C genotypes did not differ between the patients and the controls (10% vs 13.1%, P>0.05). The relative risk associated with the ACE-DD was increased by AT1R-AC genotype. Neither the number of affected coronary vessels nor the coronary score differed among the ACE I/D genotypes (P>0.05). But the number of affected coronary vessels and the coronary score were significantly greater in the patients with the AT1R-AC genotype than in those with the AA genotype (P<0.05). In conclusion, DD genotype may be risk factor for CHD and MI in Chinese people, and is not responsible for the development of the coronary artery stenosis. The AT1R-C allele may increase the relative risk associated with the ACE-DD genotype, and may be involved in the development of the stenosis of coronary artery.
