Objective To analyze the association of polymorphisms of estrogen receptor (ER) α and β genes with systemic lupus erythematosus (SLE) in Chinese Han cohort of Yunnan Province.Methods XbaⅠ and Pvu Ⅱ of ERα gene,Rsa Ⅰ and Alu Ⅰ of ERβ gene were typed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 697 SLE patients and 638 healthy controls.The frequency distribution of the alleles and genotypes were analyzed by Hardy-Weinberg equilibrium test and x2 test.Results ① For ERα gene,the frequency of minor allele of Pvu Ⅱ C in SLE patients was significantly higher than healthy controls (x2=15.427,P=0.001);the allele frequencies of XbaⅠ in SLE patients showed no significant difference compared with healthy controls (P＞0.05).The frequency of minor genotype of Pvu Ⅱ CC in SLE patients was significantly higher than healthy controls (x2=17.371,P=0.011).The frequency of two locus haplotype AATT in SLE patients was significantly lower than healthy controls (x2=6.333,P=0.012);the frequency of the two locus haplotype AACC in SLE patients was significantly higher than healthy controls (x2=7.771,P=0.038).② For ERβ gene,the frequency of minor allele RsaⅠ A in SLE patients was significantly lower than healthy controls (x2=12.595,P=0.013);the allele frequencies of Alu Ⅰ in SLE patients showed no significant differences compared with the healthy controls (P＞0.05).The frequency of minor genotype AA of Rsa Ⅰ in SLE patients was significantly higher than healthy controls (x2=41.456,P=0.000).The frequency of two locus haplotype AAGG in SLE patients was significantly higher than healthy controls (x2=37.063,P=0.000).The frequency of the two locus haplotype AAGA in SLE patients was significantly lower than healthy controls(x2=21.086,P=0.001).③ Pvu Ⅱ C was related with splenomegaly (x2=4.212,P＜0.05).The two locus haplotype AGTC of Xba Ⅰ and Pvu Ⅱ was related with edema (x2=7.898,P＜0.05).Conclusion There are associations between the polymorphisms of ERα and ERβ genes and SLE.The ERα and ERβ genes may be the susceptible genes for SLE in Yunnan Han Chinese Cohort.

Objective To explore the efficacy of intraductal chilled saline perfusion (ICSP) to reduce the thermal bile duct injury during the treatment of radiofrequency ablation (RFA) associating with occlusion of hepatic blood supply in rabbits.Methods 16 healthy New Zealand white rabbits were divided into 2 groups.Rabbits of the ICSP group were placed tubes in the common bile duct after laparotomy,and ICSP was performed during the RFA procedure accompanied with hepatic blood occlusion.While for rabbits of the non-ICSP group,hepatic blood occlusion and RFA were performed without ICSP.RFA electrodes were placed about 5 mm away from the hilus hepatis approximately.Contrast-enhanced ultrasonography (CEUS) was administrated to evaluate the sizes of the ablative zones after the procedure.On post-procedure 6 week,ultrasonography was prerformed to evaluate the changes of the biliary structure,and liver specimens of rabbits wcrc obtained for histopathologic observation of main bile ducts.Results Post-procedure CEUS examination showed that there was no significant difference in the size of the ablative zone between the groups (P ＞0.05).On post-procedure 6 week,rabbits of the ICSP group appeared with biliary dilatation more frequently by ultrasonography (P ＜0.05),and a higher degree of the injury of main bile duct by histopathologic observation (P ＜0.05).Conclusions In treatment of RFA accompanied with hepatic blood occlusion,RFA-induced bile duct injury may be decreased significantly with ICSP.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.

Schizophrenia, described as the worst disease affecting mankind, is a severe and disabling mental disorder. Schizophrenia is characterized by complicated symptoms and still lacks a diagnostic neuropathology, so developing schizophrenia animal models which have quantifiable measures tested in a similar fashion in both humans and animals will play a key role in new therapeutic approaches. According to the symptoms of cognitive impairment and emotional disorder, the N-methyl-d-aspartate (NMDA)-receptor antagonist MK-801 was applied to induce schizophrenia-like behavior in mice. Locomotor activity and prepulse inhibition (PPI) were selected as indices and the effect of clozapine was also investigated in this model. The results showed that compared with the normal group, MK-801-treated mice exhibited significantly increased locomotor activity and impaired PPI, and pre-exposure to clozapine could ameliorate the abnormality and make it back to normal level. These findings suggest that the model we established could be a useful tool for antipsychotic drug screening.

ObjectiveTo assess the differential diagnostic value of serum intestinal fatty acid binding protein (I-FABP)in distinguishing intestinal ischemia patients from acute abdomen patients.MethodsA total of 151 patients with acute abdomen and 17 healthy controls from the PLA General Hospital were enrolled from November,2009 to August,2011. Serum I-FABP levels were measured by ELISA.According to the ROC curve,the cut-off value,sensitivity,specificity,positive likelihood ratio (PLR),negative likelihood ratio ( NLR),positive predietive value (PPV) and negative predictive value (NPV) were calculated. ResultsOf the 151 acute abdomen patients,there were 24 intestinal ischemia patients and 127 without intestinal ischemia.Serum I-FABP level in intestinal ischemia group [( 109.67 ±48.82) μg/L]was significantly higher than those in patients without intestinal ischemia [(36.78 ± 11.25) μg/L]and healthy controls[(8.33 ±6.25) μg/L]( all P values ＜0.01 ).The serum I-FABP cut-off value for the diagnosis of intestinal ischemia was 87.52 μg/L.Serum I-FABP was efficient in terms of sensitivity (0.762),NPV(0.963),PLR(3.05) and NLR (0.24) in the diagnosis of intestinal ischemia.ConclusionI-FABP is potentially useful for discriminating intestinal ischemia from acute abdomen.
