Main clinical manifestations were lesion of skin and its appedants (62.04%) and gastrointestinal injury (16.06%). Most of them were mild and medium ADR. CONCLUSION: Great importance should be attached to the rational use of LVFX injection and ADR monitoring to guarantee the safety of patients.

Objectives To investigate the association between HLA-DQB1 alleles and Han Chinese with generalized pustular psoriasis (GPP) from Shandong. Methods The distributing frequencies of HLA-DQB1 alleles were detected with polymerase chain reaction-sequence specific primers (PCR-SSP) in 38 GPP patients and 94 healthy subjects from Shandong. Results ①The frequencies of HLA-DQB1*0201 and *0603 alleles increased significantly in GPP patients compared with those of the healthy controls(Pc = 0.005 and Pc = 0.013 , respectively), and the frequency of HLA- DQB1*0604 alleles decreased (OR = 0.08, Pc = 0.039). ②There were significant association between the GPP patients with a previous history of psoriasis vulgaris and HLA-DQB1*0201 and *0603 alleles (OR = 32.31, Pc = 0.005; OR = 12.42, Pc = 0.005, respectively), and between the GPP patients without the history and HLA-DQB1*0602 alleles (OR = 5.60, Pc = 0.039). Conclusions HLA-DQB1*0201 and *0603 alleles are significantly associated with the Chinese patients with GPP in Han population from Shandong. There is a significant heterogeneity in the GPP patients with and without the history of psoriasis vulgaris.

Objectives:To investigate the effects of early enteral feeding(EEF) after hemorrhagic shock(HS) on gut structure and function,hormones for stress and metabolism and nutritional conditions. Methods:Seventy two Wistar rats were randomly divided into sham shock group(SS),HS group(HS) and post HS EEF gorup(HSE).HSE group was fed with ENSURE and HS group was fed with normal saline.EEF was started within 1 hour after resuscitation.The body weight,liver weight,musculus gastrocnemius weight,nitrogen content in liver and musculus gastrocnemius,total plasma protein level,albumin level,MDA(malondialdehyde) and Na + K + ATPase activity in stomach and jejunum mucosa, the change of liver function, the levels of glucagon,cortisol and insulin,and the pathological changes in stomach, small intestine and liver were investigated at 2,6,24,48 h after resuscitation. Results:When compared with HS group,the weight of body,liver and musculus gastrocnemius,the nitrogen content in liver and musculus gastrocnemius,the levels of total plasma protein and albumin and the liver function were significantly better in the HSE group.MDA content was less and Na + K + ATPase activity was higher in HSE group than those in HS group.The glucagon and cortisol levels were significantly lower and the insulin level was significantly higher in HSE group than those in HS group.The pathological changes in the stomach,intestine and liver in HSE group got an obvious improvement. Conclusions:After HS,EEF is helpful to maintain visceral organ function,reduce the stress and hypermetabolic response and improve the nutritional conditions.
