0.05).The ultramicrostructure of cells detected by electron microscope showed that GJIC function in transfected group was higher than that in the other two groups.While in migration assay,the numbers of cells in lower chamber passing through the membrane in transfected group,blank control group and negative control group were 112?23,306?49 and 322?91, respectively;with significant differences among 3 groups(P

Objective:To investigate the expressions of peripheral lymph node addressin(PNAd)andGlcNAc-6-sulfotransferase(GlcNAc6ST)in endometrium and their impacts on implantation.Methods:PNAd expression in endometrium was examined by immunohistochemistry and Western Blot from 75women(12 from healthy women,in proliferative phase;63 from sterile women,of whom,27 were inearly-secretory and 36 in mid-secretory phase).GlcNAc6ST mRNA was examined by real-time PCR in41 sterile women.The 63 sterile women had underwent ⅣF-ET and were consequently divided into clini-cal pregnant(29 cases)and nonpregnant(34 cases)groups.Results:(1)PNAd localized to the mem-brane and cytoplasm of luminal and glandular epithelia.Staining was patchy and much less intense duringthe proliferative phase than during the secretory phase.In Western Blot of PNAd,four bands appeared,which were Sgp200,CD34,MAdCAM-1,GlyCAM-1 respectively,and each was positively correlatedwith the others significantly.The former three molecular levels were significantly higher during the secre-tory phase as compared with the proliferative phase.Message RNA of GlcNAe6ST was positive in all ca-ses and showed no correlation with any component of PNAd.(2)The expressions of CD34 and GlyCAM-1,but not Sgp200 and MAdCAM-1,were significantly higher in pregnant women than in nonpregnantones.However,the GlcNAc6ST mRNA level did not differ between groups.(3)No significant differ-ence was found in female age,methods of fertilization,thickness of endometrium on day hCG,cumulativeembryo score(CES)and mean score of transferred embryo(MSTE)between the groups.Conclusion:PNAd expression in the human endometrium fluctuates with the menstrual cycle.Elevated CD34 and Gly-CAM-1 during the secretory phase might be stimulative factors for embryo implantation.Defect in PNAdexpression may account for a portion of unexplained infertility.

Objective To evaluate the clinical effect of traditional Chinese medicine fumigation and herbal plaster for the patients with anal abscess. Methods A total of 140 patients with anal abscess were randomly divided into 2 groups, 70 in each group. The control group were treated with different operation methods according to the patient's health condition. the Potassium Permanganate solution (1:5 000) bath was used after surgery in the conventional anti anti-infection treatment; and the observation group were treated with herbal fumigation and plaster on the basis of the control group. The wound was treated in the both groups in the following 3 months after operation. The wound swelling disappearance, carrion shedding and healing time, pain relief, medical records of infection and recurrence were measured after the treatment and follow-up period. Results The total effective rate of the observation group was 100% (70/70), and the control group was 91.4% (64/70). The difference between the 2 groups was statistically significant (χ2=4.322,P=0.037). After 3, 7 days, the pain relief in the observation group was better than that in the control group (Z=9.742, 16.860,P=0.008, 0.001). After treatment, the observation group swelling (4.9 ± 0.7 dvs. 6.1 ± 0.7 d,t=10.142), carrion shedding time (3.8 ± 0.5 dvs. 4.2 ± 0.4 d,t=5.227), the wound healing time (22.1 ± 4.0 dvs. 26.9 ± 4.0 d,t=7.099) were lower than those in the control group (P<0.01). During follow-up, 4 cases (5.7%) with secondary infection and 2 cases (2.9%) with recurrence were in the observation group, but 20 cases (28.6%) and 6 cases (8.6%) in the control group.There were significantly difference of the secondary infection and recurrence between two groups (χ2= 6.092,8.934,P= 0.034, 0.001). 2 groups of secondary infection, the differences were statistically significant. Conclusions The combination of traditional Chinese medicine fumigation and herbal plaster could improve the wound healing time, reduce the secondary infection and recurrence rates of patients with anal abscess.

OBJECTIVETo investigate the comprehensive treatment of stage-IIIb testicular non-seminomatous germ cell tumor (NSGCT) based on the chemotherapy with cisplatin, etoposide and bleomycin (BEP) and nerve-sparing laparoscopic retroperitoneal lymph node dissection (nsLRPLND).

METHODSWe reported a case of stage-IIIb testicular NSGCT, analyzed the clinical data and treatment methods and reviewed the relevant literature.

RESULTSThe patient underwent chemotherapy with etoposide (0. 18 g/d for the first 3 days), cisplatin (30 mg/d for the first 5 days), and bleomycin (30 mg/d on day 2, 9 and 16) for 3 cycles, followed by nsLRPLND. Both chemotherapy and surgery were successfully performed. The operation time was 175 min, with intraoperative blood loss of 50 ml, but no severe perioperative complications. No recurrence and distant metastasis were found during the 6-month follow-up after surgery.

CONCLUSIONThe comprehensive treatment based on BEP chemotherapy and nsRPLND can be used as an option for stage-IIIb testicular NSGCT.

Human tumor suppressor gene beclin 1 regulates cell growth through autophagy. The mRNA expression of beclin 1 was reported to be down-regulated in breast cancer with high frequency of loss of heterozygosity (LOH). However, there was no report about the expression levels or the regulatory mechanisms of beclin 1 in gastric and colorectal cancer. Both the mRNA and protein expression levels of beclin 1 was detected in the tissues of gastric and coiorectai cancers, as well as the aberrant DNA methylation and LOH related to the expression of beclin 1. By comparing with normal tissues adjacent to the tissue of these tumors, it was found that beclin 1 mRNA expression levels were significantly decreased in gastric tumor tissue. Furtherly by explorating the 5' region of beclin 1 gene sequence, a large and dense CpG island was discovered and meanwhile methylations in the promoter and the intron 2 regions of beclin 1 were found in both gastric and colorectal tumors. And LOH was found in gastric tumors. These findings suggested that aberrant DNA methylation, as well as LOH, were involved in the regulation of beclin 1 expression in gastric and colorectal cancer.

Objective To evaluate the efficacy of preoperative regional intra-arterial chemotherapy (RIAC) in the treatment of resectable pancreatic head carcinoma. Methods The clinical data of 50 patients with resectable pancreatic head carcinoma who had been admitted to the Research Institute of Pancreatic Diseases of Fudan University from December 2006 to July 2007 were retrospectively analyzed. Patients were randomly divided into2 groups (n =25 in each group): patients in group A were treated with preoperative RIAC followed by regional pancreaticoduodenectomy, and patients in group B were treated with surgical procedure routinely. The lymphatic metastases in the 50 specimens of pancreatic head carcinoma were detected by histological examination with hematoxylin and eosin (HE) staining, and lymphatic micrometastases were detected by immunohistochemical method with staining of cytokeratin AE1/AE3 in 10 specimens with negative HE staining of the lymph nodes in each group. Results There was no significant difference in the incidence of complications, the length of hospital stay and the 1-, 2-year survival rates between the 2 groups (χ2 = 0.12, 2.88, P > 0.05). The incidence of positive lymph node metastasis in group A was 7.1% (52/734), which was significantly higher than 22.1% (118/532) in group B (χ2 = 60.01, P < 0.05). The incidence of lymphatic micrometastasis was 9.4% (30/319) in group A, and 9.1% (23/252) in group B, with no statistical difference between the 2 groups (χ2= 0.01, P > 0.05). Conclusions Preoperative RIAC is helpful in improving the prognosis of patients with resectable pancreatic head carcinoma by reducing the incidence of lymphatic metastasis and decreasing tumor stage.
