claudin protein is the major component of tight junctions complex between cells,which plays an important role in cells junction and adhesion. Its specific expression in different tissues directly affects the biological behavior of tumor cells. In pancreatic tumors, the claudin's expression provides an important refer-ence for the diagnosis and treatment of tumors. In addition, claudin are involved in the proliferation and ap-optosis of tumor cells. In the treatment of tumors, claudin-mediated targeting therapy has great prospects forthe same.

The serum levels of visceral adipose tissue-derived serine protease inhibitor (vaspin)were measured in 65 elderly type 2 diabetic patients with carotid atherosclerosis( T2DM + CA group), 63 elderly type 2 diabetic patients without carotid atherosclerosis (T2DM group ) and 55 normal elderly individuals( NC group)by enzyme-linked immunosorbent assay. The results showed that the serum vaspin levels in T2DM + CA group were significantly lower than those in T2DM group[(0. 23 ± 0. 13 ) μg/L vs.(0. 41±0. 16)μg/L, P ＜0. 01]. The serum vaspin levels in T2DM + CA group and T2DM group were significantly lower than those in NC group respectively[(0. 63 ± 0. 11 ) μg/L, P ＜ 0. 01 and P ＜ 0. 05].Logistic regression analysis showed that high sensitivety C-reactive protein and Homeostasis Model Assessment insulin resistance index (HOMA-IR) were negatively correlated with serum vaspin levels,which indicates that lower serum vaspin levels might be associated with the pathogenesis of carotid atherosclerosis in elderly type 2 diabetic patients.

OBJECTIVE:To observe therapeutic efficacy and safety of Zhenqi fuzheng granules in the adjunctive treatment of cervical cancer. METHODS:86 patients with cervical cancer were randomly divided into control group(43 cases)and observation group (43 cases). Control group was given intravenous dripping of Diphenhydramine hydrochloride injection 20 mg,Granisetron hydrochloride and glucose injection 5 mg,Cimetidine injection 20 mg at 0.5 h before chemotherapy. After 0.5 h of intravenous drip-ping,the patients received chemotherapy:Docetaxel injection 40 mg/m2,d1,d8,intravenous dripping;Cisplatin for injection 25 mg/m2,d1-3,intravenous dripping;21 d as a cycle,a total of 4-6 cycles. On the basis of control group,observation group was addi-tionally given Zhenqi fuzheng granules 5 g,twice 2 day. Clinical efficacies of 2 groups were observed as well as T cell subsets in-dexes [CD3+,CD4+,CD8+,natural killer cell(NK)],KPS scores,termination,terminal time,the times of chemotherapy and the oc-currence of toxic reaction before and after treatment. RESULTS:The total remission rate of observation group was significantly higher than that of control group;the proportion of termination of chemotherapy in observation group was significantly lower than control group;terminal time of chemotherapy was significantly shorter than control group;the times of chemotherapy was signifi-cantly more than control group;the incidence of gastrointestinal reaction,anemia,thrombocytopenia and leukopenia were signifi-cantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in liver function dam-age,renal function injury and stomatitis between 2 groups (P>0.05). Before treatment,there was no statistical significance in T cell subsets indexes and KPS scores between 2 groups(P>0.05). After treatment,CD3+,CD4+ and NK cells in observation group were significantly higher than before treatment and control group,while CD8+ was significantly lower than before treatment and control group;KPS scores of 2 groups were significantly higher than before,and the observation group was significantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in T cell subsets indexes of con-trol group before and after treatment(P>0.05). CONCLUSIONS:On the basis of routine treatment,Zhenqi fuzheng granules can improve therapeutic efficacy,immune function and the quality of life,moreover,reduce toxic reaction in patients with cervical can-cer.

Objective The electrophysiological parameters of atrioventricular conduction function in patients with atrioventricular nodal reentry tachycardia (AVNRT)were analyzed,and to explore the effect of different ablation endpoints on atrioventricular conduction function in patients with AVNRT.Methods 96 cases with AVNRT under-went radiofrequency catheter ablation (RFCA)of slow conduction pathway.According to whether the slow pathway eliminated,the patients were divided into the slow pathway disappeared group and slow tracks remaining group.Preop-erative and postoperative intracavitary electrophysiological examination and atrioventricular function data were recor-ded,including before and after radiofrequency ablation of bundle of HIS,PA,AH,HV interval,atrioventricular prequel venturi point(AVN -WKB),ventriculoatrial retrograde venturi point(VAN -WKB),atrioventricular node prequel effective refractory period(AVB -WKB).Patients were followed up by telephone for a year.Then,a comparative anal-ysis of preoperative and postoperative was done.Results RFCA of AVNRT patients with atrioventricular node pre-quel time effect:RFCA and preoperative ratio,after his bundle electrogram PA,ah,HV interval had no significant changes(P >0.05).Effect of RFCA surgery on patients with AVNRT refractory atrioventricular node prequel:com-pared with RFCA before surgery,postoperative slow pathway disappear fast pathway shortening of effective refractory period[preoperative(287.5 ±46.2)ms,postoperative(260.2 ±55.6)ms,t =2.901,P =0.005],slow pathway effec-tive refractory period[disappear preoperative(243.3 ±43.2),postoperative(0.0 ±0.0)ms,t =43.290,P =0.000], AV node Wenckebach point in advance before operation[(261.3 ±44.3)ms,postoperative(293.2 ±46.2)ms,t =3.828,P =0.000];group after slow pathway to improve fast pathway effective refractory period without obvious change (P >0.05 ),the slow pathway effective refractory period in high concentration [preoperative (242.2 ± 42.8)ms,postoperative(281.2 ±41.3 )ms,t =3.879,P =0.000〗,atrioventricular node Wenckebach point in advance before operation[(261.5 ±43.5)ms,postoperative(291.3 ±46.5)ms,t =2.769,P =0.007〗.Comparison between groups,after slow pathway disappeared group fast pathway effective refractory period was significantly shorter in the slow diameter improvement group,but between the two groups in the atrioventricular node Wenckebach point differences was not statistically significant(P >0.05).There was no recurrence in the follow -up after a year of slow path loss and slow pathway.Conclusion RFCA caused by slow pathway to disappear or modified two slow pathway ablation right AVNRT patients atrioventricular time had no effect,but all the atrioventricular junction the prequel's point advance.The atrioventricular node slow pathway disappear fast and effective pathway refractory period short-ened,slow pathway improved the slow pathway effective refractory period.RFCA surgery done by the slow pathway dis-appeared or slow pathway ablation is effective in patients with AVNRT,and there was no significant recurrence rate in both groups within 1 year.
