To study the relationship between HLA DRB1*07 and the susceptibility to HBV in the Han nationality in Guangdong Province. 100 chronic HBV carrier individuals, 21 HBV spontaneously cleared individuals and 70 HBV unexposed individuals all of Han nationality in Guangdong Province were entered in this study. The expression of HLA DRB1*07 alleles were detected by polymerase chain reaction sequence specific primer, and IFN ? and IL 4 levels in plasma of HBV chronic carrier individuals were measured by using ELISA kits. The results showed that the positive rate of HLA DRB1*07 in chronic HBV carriers was 30%, which was markedly higher than that in HBV spontaneously cleared individuals(4 76%) and HBV unexposed individuals (8 5%) as well ( P

Objective To explore the method for establish the temporal lobe epilepsy model in SD rats with stereotactic technique and to study the characteristic of electroencephalography (EEG) after epileptic seizure. Methods Kainic acid was injected into right hippocampus via stereotactic technique in 20 rats, and the behavior of rat was recorded by a video camera. The electrical activity changes of brain were recorded by EEG in bilateral hippocampus, amygdala and frontal lobe. Results According to Racine's scale, 6 rats were typeⅤ,10 rats were type Ⅳ,3 rats were type Ⅲ,1 rat was type Ⅱ. The spike wave was originated from hippocampus and spread to amygdala and frontal lobe. Pathologic changes showed that prolonged seizures induced pyramidal cell loss and death in hippocampus. Conclusions The method to establish kainic acid induced temporal lobe epilepsy model with stereotactic technique was credible, economical and useful. The spike wave originated from hippocampus was the basic feature of EEG of temporal lobe epilepsy model in rats.

Objective To observe the effects of soybean isoflavone in attenuating trans fatty acids-induced athero-sclerosis in rats .Methods The rats were randomly divided into normal diet group、trans fatty acids group、soybean isoflavone group and trans fatty acids +soybean isoflavone group .Research kit was used to test the amounts of TG , HDL,LDL and IL-6,TNF-αin rats'blood.Bovine aortic endothelial cells were cultured and divided into control group,trans fatty acids group and trans fatty acids group +soybean isoflavone group .Western blot was performed to test the NF-κB phosphorylation ,as well as to determine ICAM-1 and VCAM-1 protein contents in bovine aortic endo-thelial cells.Results Compared with normal diet group ,the amounts of TG,LDL,IL-6,TNF-αincreased evidently (P<0.05), whereas the amounts of HDL decreased evidently (P<0.05) in the rats'blood of trans fatty acids group . After the soybean isoflavone intervened ,the amounts of TG,LDL,IL-6,TNF-αall decreased (P<0.01), meanwhile the amounts of HDL increased significantly (P<0.01).Soybean isoflavone inhibited NF-κB phosphorylation induced by trans fatty acids ( P<0.01) .The high expression of ICAM-1 and VCAM-1 induced by trans fatty acids was de-creased by soybean isoflavone when comparing with those in the control group ( P<0.01 ) .Conclusions Soybean isoflavone has a role in attenuating trans fatty acids trans fatty acids-induced atherosclerosis in rats .

OBJECTIVETo explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.

METHODSTotally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.

CONCLUSIONSMore severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.

Objective To understand the health status of medical staffs in a tertiary hospital of Chongqing City to provide the basic information and scientific basis for formulating the interventional measures.Methods The physical examination data of 1 397 medical staffs in 2013 and 2 178 medical staffs in 2015 were selected as the research objects and performed the summary analysis according to the abnormal indexes distribution,sex and age.Results A total of 1 397 persons completed the physical examination in 2013,the abnormal indexes were detected in 1 250 people,the detection rate of sub-health status was 89.48％;2 178 people in 2015 completed the physical examination,the abnormal indicators were detected in 2 046 people,the detection rate of sub-health status was 93.94％.The comparison of two-year health examination data showed the different degrees of increasing trend in bilateral breast hyperplasia,gallbladder polyps,thyroid cysts,low density lipoprotein cholesterol.Conclusion The health status of medical staffs is not optimistic,so the self health care consciousness of medical staffs needs to be elevated.

OBJECTIVE:To evaluate the therapeutic effect of compound glycyrrhizin plus mizolastine for patients with generalized neurodermatitis(GND)and its influence on patietents' psychology.METHODS:60 patients with GND were randomly assigned to receive compound glycyrrhizin plus mizolastine(treatment group)or mizolasitine alone(control group)for 28 days.The psychological factors were examined before and after treatment using self-rating anxiety scale(SAS),and the curative effects and the psychological changes between two groups were compared.RESULTS:The SAS scores of treatment group and control group were 30.53? 1.50 and 33.20? 1.67,respectively(P

Objective To explore the clinical significance of serum clara cell secretory protein(CC16),total immunoglobulin E(TIgE)and eosinophil cationic protein(ECP)in children with asthma.Methods Serum were collected from 59 cases during asthmatic acute attacks,29 asthmatic children who were in mild conditions,and 30 cases who were in moderate to severe conditions,and 30 healthy children.Serum CC16 concentration were measured by enzyme-linked immunosorbent assay(ELISA),TIgE and ECP concentration were measured by uniCAP100.Results The levels of CC16 in serum of asthmatic children during acute attacks were significantly lower than that in control group(t=2.93 Pa

Osteoclasts are derived from pluripotent stem cells in bone marrow and spleen.They play a critical role in inflammation-induced bone loss and joint destruction because in the absence of them,bone de- struction does not occur even when inflammation exists.Synovioblasts in an inflamed joint can secrete numerous inflammatory factors,including tumor necrosis factor alpha(TNF-?)and interleukin-1(IL-1)which not only induce inflammatory reactions but also elevate osteoclast formation and function indirectly or directly through promoting RANKL expression.In this wdy the inflammatory reactions are associated with bone loss and destruction. In this article,we focus on the recent progress in study of TNF-?,IL-1 and osteoclast-target therapies in management of osteoclast-mediated inflammatory bone loss.TNF-?promotes differentiation of osteoclast precursor cells in the peripheral blood and spleen,which causes a marked increase in mature osteoclasts in a diseased joint.However, IL-I supports osteoblast survival and regulates the recombination of osteoclast cytoskeleton,which further stimulates bone resorption.Since osteoclast-target therapies may inhibit osteoclast formation and function,they are becoming more and more important for inflammation-induced bone loss and joint destruction.
