OBJECTIVETo explore effective pretreated methods for hydrosalpinx before frozen embryo transfer (FET).

METHODSA randomized controlled study was performed on 229 FET cycles of hydrosalpinx patients. They were assigned to two groups by random digit table, Group A (94 cases), Group B (89 cases), and Group C (46 cases). Patients in Group A received transvaginal aspiration of hydrosalpinx combined with auricular point sticking. Those in Group B received transvaginal aspiration of hydrosalpinx group. Those in Group C received no transvaginal aspiration of hydrosalpinx. Pregnancy outcomes of FET, endometrial and subendometrial blood flow distribution on the embryo transfer day were compared among the three groups.

RESULTSThere was no statistical difference in the endometrial thickness on FET day, the number of transfer embryos, the number of transferred good quality embryos among the three groups (P > 0.05). The clinical pregnancy rate and the embryo implantation rate were significantly higher in Group A than in Group C (P < 0.05), and the clinical pregnancy rate was significantly higher in Group A than in Group B (P < 0.05). The early abortion rate and the transfer cycle cancel rate were significantly lower in Group A than in Group C (P < 0.05). Type A endometrial and subendometrial blood flow distribution was dominant in Group A, which was significantly higher in Group A than the rest two groups (P < 0.05). Type A distribution rate was also significantly higher in Group B than in Group C (P < 0.05).

CONCLUSIONTransvaginal aspiration of hydrosalpinx combined with auricular point sticking before FET could improve the endometrial receptivity and improve outcomes of IVF.

Objective To analyze the genetic characteristics of breakthrough varicella-zoster virus infection during the varicella outbreaks in Minhang District of Shanghai in 2013-2014. Methods Samples of the varicella-zoster liquid were collected from patients with chickenpox in Minhang District in 2013-2014 and used for the extraction of genomic DNA. The open reading frame ( ORF) of 22 and 62 regions were se-quenced and further analyzed by using bioinformatics methods. Results A total of 24 samples were success-fully collected and sequenced, and all of them were wild strains. Among the 24 varicella-zoster virus strains, 23 strains were highly homologous to the parental strain ( P-Oka) and the vaccine strain ( V-Oka) , indica-ting that they belonged to J genotype. Only one strain, whose genotype was between M and E, was highly ho-mologous to the mosaic( M) CA123 strain ( M1 genotype) , indicating that it might belong to M1 genotype. Conclusion The epidemic strains of varicella-zoster virus in Minhang District were mainly J genotype. Lo-cal epidemic of M and other genotypes of varicella-zoster virus also existed. There were some gene variations in different strains of J genotype. These varicella-zoster virus strains of non-vaccine genotypes might be one of the reasons causing the breakthrough cases of chicken pox.

AIM: To explore the probable mechanisms of diabetes-induced arrhythmias. METHODS: Diabetes was induced in male SD rats,using a single injection of alloxan into tail vein. Untreated age-matched animals were used as controls. All animals were observed by 2,4,6 and 8 weeks,respectively. Transmembrane potentials were recorded with conventional glass microelectrodes. RESULTS: Action potential duration(APD) at all level (APD10,APD20,APD30,APD50,APD70,APD90) was significantly lengthened in right ventricular papillary muscle from week 2 of diabetes. At week 8,APD was more lengthened at any level of repolarization than that at week 2. No differences were observed in the maximum rate of depolarization(V_ max ),overshoot(OS) and action potential amplitude(APA) as well as the resting membrane potential(RP) from the 2th to 8th week of diabetes. CONCLUSION: The results indicate that prolongation of APD may be prominently responsible for the increased incidence of cardiac re-entry-arrhythmias and sudden death,especially at late stages of diabetes.

Objective To evaluate the accuracy and clinical application of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in diagnosis of occupying lesions in upper digestive tract and its pe-ripheral areas. Methods The data of 64 patients who underwent EUS-FNA for occupying lesions in upper di-gestive tract, between July 2006 and December 2007, were retrospectively analyzed. Results EUS-FNA was successfully performed on 62 patients, with a success rate of 96.88%. The overall diagnostic accuracy, sensi-tivity, specificity, positive predictive value and negative predictive value of EUS-FNA for occupying lesions in upper digestive tract and its peripheral areas were 88.71%, 86.54%, 100.00%, 100.00%, and 58.82%, respectively. There was no significant difference between the foei larger and smaller than 3cm (P > 0.05), re-garding the diagnostic accuracy and average puncture numbers. Diagnostic accuracy of those with real-time cy-tolngical evaluation was significantly higher than those without (P=0.029), and the puncture numbers were less (P=0.001). Among the total 99 punctures, the positive diagnostic accuracy of those with 5ml negative pressure suction was significantly higher than those of 10 ml (P = 0.044). Conclusion EUS-FNA is a safe and applicable approach to diagnosis of occupying lesions in upper digestive tract and its peripheral areas with higher diagnostic accuracy, sensitivity, specificity and positive predictive value. Moreover, the real-time cyto-logical evaluation and adequate negative pressure might facilitate the diagnosis accuracy.

OBJECTIVETo investigate the influence of Kudou Shencha decotion on INF-y, ICAM-1, MCP-1 levels of prostate tissue homogenate in immunity prostatitis model rats.

METHODForty Wistar male rats were divided into 5 groups randomly: Kudou Shencha decotion group with high dosage and low dosage, Qianleitai group, the model control group and normal group. The rat model of chronic nonbacterial prostatitis was established by multiple hypodermical injection of the suspension of prostatic protein purification with Freund's completed adjuvant. The level of intercellular adhesion molecule (ICAM-1), interferon gamma (INF-gamma) and monocyte chemotactic protein-1 (MCP-1) were measured by enzyme linked immunosorbent assay (ELISA).

RESULTThe content of ICAM-1 and MCP-1 in the model group was higher than that of the normal group (P < 0.05), the content of ICAM-1 was obviously decreased in Kudou Shencha decotion group with high dosage (P <0.05), the contents of MCP-1 were all obviously decreased in Kudou Shencha decotion groups and Qianlietai group. Compared with the model group, the contents of INF-gamma in all treatment groups were decreased insignificantly.

CONCLUSIONKudou Shencha decotion has the action of lowering the level of ICAM-1 and MCP-1, which may be one of the mechanisms of Kudou Shencha decotion in the therapy of chronic prostatitis.

Objective To explore the activated brain region of acute epilepsy in cat model induced by pentylenetetrazol(FFZ)with manganese enhanced-functional MR imaging(ME-fMRI),and evaluate the application of ME-fMRI on localization of the activated brain.Methods Forty cats were divided into 4 groups by random number table method as epileptic A and B groups as well as control A and B groups. Cats of epileptic groups were injected with PTZ(55 mg/kg)intramuscularly,and those of control groups were injected with the saline at same dose.The behavior change in the epileptic and control group A was observed and electroencephalogram(EEG)was also undertaken.Cats of epileptic and control group B were performed ME-fMRI,and the percentage of the enhanced signal intensity was then calculated.Results After injection with PTZ(55 mg/kg)intramuscularly,epileptic seizure was all evoked,and then EEG recording showed spike-wave and polyspike-wave complexes.The neocortex of cats of epileptic group B was diffusely phanero-enhanced on ME-fMRI.The percent enhancement of signal intensity in cortex of frontal lobe,parietal lobe and occipital lobe was(34.6?5.7)% and that in cortex of temporal lobe with(22.9? 6.5)%,whereas those of control group B with(14.9?4.5)% and(11.6?3.2)% respectively.And there was significant difference between the above different localization of the brain in the two groups (t=-10.43,-5.46 respectively,P
