10 mU/L (GroupⅡ,71 cases) when they were one year old.There were 40 healthy children in control group. The genomic DNA from the peripheral blood was extracted and polymerase chain reaction (PCR) and sequencing were employed to detect the IL-12B gene 3′UTR+1188 SNP.Results The frequency of AA,AC and CC genotype in GroupⅠwere 25.7%,44.3% and 30.0% respectively,and 36.6%, 47.9% and 15.5% in GroupⅡ,48.8%,39.0%,12.2%,in control group,respectively.The differ- ence of frequency of CC genotype and non-CC genotype between GroupⅠand GroupⅡwas significant (x~2=17.078,P

ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

Objective:To compare the efficacy and safety between cryoablation(Cryo)and radiofrequency (RF)ablation in patients with atrioventricular nodal reentrant tachycardia(AVNRT). Methods: A total of 83 patients with AVNRT underwent electrophysiological treatment in our hospital from October 2006 to March 2009 were studied. Patients were divided into two groups according to their own choices. Cryo group (n=41) and RF group (n=42). The clinical characteristics,success rate,procedural time and ablative time were compared between two groups. Results:The procedural time and ablative time in Cryo group was significantly longer than those in RF group (119.14±40.16 min vs.85.86±28.24 min,P=0.001; 1118.91±620.62 s vs.370.97±279.23 s,P<0.001). The acute success rate was achieved in 40/41(97.6%)patients in Cryo group,and 42/42(100.0%) in RF group. Transient AV-block was encountered in 6 (15%) patients in the Cryo group and 5 (11.9%) in RF group (P=0.681). There was no complete atrial-ventricular(AV)conduction block at the end of procedures. There was no recurrence of AVNRT in either Cryo group nor in RF group during 11.6±5.5 months of follow up period.Conclusion:Cryoablation was as effective and safe as RF ablation for AVNRT. Cryo-energy was one kind of alternative ablation energy for AVNRT.

Objective To analyze the characteristic of serum proteins in non-small cell lung cancer (NSCLC) patients, establish serum markers pattern for the diagnosis of NSCLC. Methods Surface enhanced laser desorption ionization time of flight mass spectormetry ( SELDI-TOF-MS) technology was used to analyze serum samples. Bio-marker Pattern Software (BPS) was used to detect the protein peaks. Results Sixteen significantly different pro-tein peaks were found in serum samples in NSCLC patients and healthy controls. Eight up-regulated protein peaks and eight down-regulated protein peaks ( P < 0. 001 ) were identified in serum samples of NSCLC patients. Three up-regulated protein peaks(P <0. 05) were identified in serum samples of patients of NSCLC with smoking history. Two up-regulated protein peaks(P <0. 01) were identified in serum samples of patients of squamous carcinoma comparing with adenocarcinoma. No significantly different protein peak was found in serum samples of NSCLC patients at different clinical stages . Conclusion SELDI - TOF - MS technology can identify different protein peaks and so function as a diagnostic tool with high sensitivity and specificity.

BACKGROUND:Immortalized cervical epithelial cels H8 can become cancerous under the induction of carcinogenic agent, and may cause cervical cancer when there is a cofactor interaction. However, there is stil a lack of effective intervention for female patients with precancerous lesions, and this treatment is blank in the clinic. OBJECTIVE: To explore the effects and mechanism of astragalus injection on apoptosis of human immortalizedcervical epithelial cels H8. METHODS: This study contained two groups: astragalus drug group and the blank control group. (1) Enzyme linked immunosorbent assay (ELISA) was used to detect DNA fragments of apoptotic H8 after astragalus injection. (2) Enzyme-labeling instrument was used to analyze the changes in caspase-3 and caspase-9 activities a fter astragalus injection. (3) Western blot assay was used to detect the protein expression changes of caspase-3, caspase-9 and PARP in H8 cels after astragalus injection. RESULTS AND CONCLUSION: (1) ELISA results showed that at 0, 6, 12 and 24 hours after 20 g/L astragalus injection, DNA fragments were gradualy increased with time prolonged in a time-dependent effect (P < 0.05). (2) Enzyme-labeling instrument demonstrated that at 0, 6, 12 and 24 hours after 20 g/L astragalus injection, caspase-3 and caspase-9 activities increased in a time-dependent manner (P < 0.05). (3) At 0, 6, 12 and 24 hours after 20 g/L astragalus injection, the expression of cleaved caspase-3 and cleaved caspase-9 were gradualy increased in H8 cels (P < 0.05). Cleaved PARP protein expression was gradualy decreased (P < 0.05). These findings indicate that astragalus injection could obviously induce H8 apoptosis, which may be associated with the upregulated protein expression of caspase-3 and caspase-9.
