Objective To study the clinical efficacy of the injection Salvia (freeze-dried, abbr: Salvia powder needle), with fallopian tube recanalization on the treatment of oviduct obstructive infertility. Methods One hundred and ninety-five patients of oviduct obstructive infertility were enrolled in this study and divided into drug group and control group. Salpingography with modified catheter, recanalization and perfusion operation were performed in both two groups. Salvia powder, gentamicin, α-ACT and dexamethasone were injected into test group, while Gentamicin, α-ACT and dexamethasone were injected into control group. Recanalization rate of fallopian tube, rate of intrauterine gestation and rate of ectopic pregancancy were measured and compared between two groups. Results Twelve months after operation, recanalization of fallopian tube of test group and control group was 94.39% and 85.87%, respectively. Twenty-four months after operation, intrauterine gestation rate of test group and control group was 50.00% and 35.71%, respectively. Conclusion Salvia powder combined with modified recanalization operation is helpful to improve the rate of intrauterine gestation.

The migration-time in transient isotachophoresis (tITP) separation is affected by sample salinity as the dependence of ITP time on sample-zone conductivity.The sample-to-sample variation of migration-time in microchip tITP-CGE analysis is an undesired factor for precise DNA sizing.In this work, a DNA sizing method that based on relative migration-time proportion (RMP) was developed to eliminate the effect of sample salinity on sizing precision.RMP was defined as the ratio of the migration-time difference between the target fragment and the lower marker to that between the upper marker and the lower marker.The RMP values were tested to be reproducible in microchip tITP-CGE separations irrespective of sample salinity.Size of a target DNA was predicted by fitting its RMP value to the equation derived from RMPs of standard DNA ladder vs.DNA sizes.The precision and reproducibility of the sizing method were validated testing multiple standard PCR amplicons.Experimental results showed that the RMP method is simple and reliable, thus well suited to precise DNA sizing with microchip tITP-CGE analysis.

Objective To investigate the role of platelet indices in the differentiation of thrombocytopenia caused by bone marrow diseases and thrombocytopenia caused by non-marrow diseases.Methods Mean platelet volume(MPV),platelet crit(PCT)and platelet size deviation width(PDW)of 76 othromboeytopenia(TP)patients,66 immune thrombocytopenia purpura(ITP)patients,8 secondary thrombocytocritpenia purpura(STP)patients,8 acquired pure megakaryocytic thrombocytopenia purpura(AATP)patients,140 malignant hematological diseases(MHD)(including acute leukemia,aplastic anemia and myelodysplastic syndromes)patients and 100 healthy people were respectively determined by blood cell analyzer Cell-Dyn 3700.Result Compared with control group,the MPV of the patients with MHD significantly decreased,and then the PDW of them increased.For patients with STP,the MVP and PDW markedly increased.The MVP of patients with AATP was normal,and PDW significantly increased.The MPV,PCT and PDW of ITP and TP showed marked difference(P＜0.01).In contrast with the control group,the MPV,PCT and the PDW of patients with hemopathy and patients with ITP were remarkably different(P＜0.01).Compared with the marrow TP and the non-marrow TP or control group,MPV and PDW showed significant difference(P＜0.01).During the effective treatment of patients with ITP,PLT increased and then MPV and PDW decreased.Conclusion The level changes of MPV and PDW,in particular MPV can primarily judge the cause of thrombocytopenia (MPV＜reference value as caused by bone marrow diseases but MPV＞reference value as caused by bone marrow diseases).In addition,during the effective treatment of patients with ITP,with changes of MPV and PDW present 5 days earlier than that of PLT,may used to observe the therapeutic effect.Myelodysplastic syndromedynamic observation of the platelet parameter helps for the differential diagnosis,judgment of the states of the diseases and observation of the effectiveness of therapy of ITP.

Objective To assess the characteristics of abdominal hernia and summarize the therapeutic efficacy of mesh plug tension-free hernioplasty in elderly ventral hernia. Methods All 207 elderly patients with abdominal hernia who were admitted to our hospital during January 1999 to December 2001 and received the mesh plug tension-free hernioplasty were analyzed retrospectively. Results There were 405 patients receiving the mesh plug tension-free hernioplasty from 1999 to 2001, in whom 207 had elderly ventral hermia. Among the 207 elderly patients, 144 had inguinal oblique hernia, 38 direct hernia, 11 direct and indirect hernia, 6 sliding hernia, 6 incisional hernia, 1 femoral hernia, and 1 femoral and inguinal direct hernia. Postoperative complications were urinary retention(8 cases), hypoincisional hematoma(4), scrotal hydroceles(1), and incisional infection (1). One hundred eithty-seven patients were followed-up for 4-40 months and no recurrence was found. Conclusions The mesh plug tension-free hernioplasty is of advantages for elderly abdominal hernia, such as simpleness in performance and a good therapeutic effect. It is especially suitable for the elderly patients due to less trauma and low recurrence rate. It is also important to pay attention to the postoperative complications to the elderly.

The incidence of esophagogastric junction cancer (EGJC) is rising dramatically both in western countries and in China.For type Ⅱ EGJC,controversies over the optimal surgical approach still remain.More and more studies support the abdominal transhiatial extended gastrectomy to be superior to the abdominothoracic combined approach.The aim of this report is to evaluate the feasibility and safety of laparoscopic transabdominal hiatal extended gastrectomy for surgical treatment of type Ⅱ and Ⅲ esophagogastric junction cancer.Based on clinical experience of 95 patients who underwent laparoscopic tansabdominal hiatal extended gastrectomy,we conclude that laparoscopic transabdominal hiatal extended gastrectomy is feasible and safe,offering a safer and simpler way of intramediastinal dissection and digestive tract reconstruction at experienced hands as compared with open surgery.This procedure also offers the merit of longer esophageal resection length without entering the pleural cavity.

0.05). Conclusions There is no difference in immune responses to rectal cancer patients undergoing laparoscopic total mesorectal excision with anal sphincter preservation and those having open surgery.

This study was conducted to explore whether cholecystokinin-B/gastrin receptor (CCKBRwt) gene and its alternative splicing variant (CCKBRi4sv) are expressed in human gastric carcinomas cell line and tissues, and to find out their relationship with the development and progression of human gastric carcinoma. The mRNA expression levels of CCKBRwt and CCKBRi4sv were detected in 30 human gastric carcinomas and normal tissues adjacent to cancer, 10 gastritis specimens, 2 autopsied normal stomach specimens as well as in a gastric carcinoma cell line SGC-7901 cells. The results revealed that the transcripts of CCKBRwt and CCKBRi4sv were observed in all of the human gastric specimens tested, but only CCKBRwt was expressed in gastric cancer cell line SGC-7901 cells. The expression levels of the two receptors were not correlated with the differentiation and metastases of gastric cancers. From the results, we infer that human gastric tissues simultaneously express CCKBRwt and CCKBRi4sv, and CCKBRi4sv may have unknown physiological functions in gastric epithelial cells.

OBJECTIVETo evaluate the effect of placement of urethral catheter combined with lidocaine on urethral irritation caused by postoperative indwelling catheters.

METHODSA total of 120 male surgical patients requiring postoperative indwelling catheters between June 2011 and January 2012 were divided into two equal groups for placement of painless urethral catheter combined with bladder washing with lidocaine on the first postoperative day, or for routine catheter placement only. The symptoms of urethral irritation such as urethral pain, urinary urgency, and perineal discomforts were observed and compared between the two groups.

RESULTSIn patients with painless urethral catheter placement combined with bladder washing with lidocaine, 11 developed urethral irritation symptoms, as compared to 24 in the patients with routine catheter placement only, showing a significant difference between the two groups (P<0.05).

CONCLUSIONPlacement of painless urethral catheter combined with bladder washing with lidocaine can significantly reduce the incidence of urethral irritation due to postoperative indwelling catheters.

OBJEVTIVETo investigate the expression of cysteine-rich secretory protein 2 (CRISP2) in spermatozoa of patients with asthenozoospermia and explore its clinical significance.

METHOSSemen samples were collected from 24 normal volunteers and 24 patients with asthenozoospermia for detecting CRISP2 mRNA and protein expressions using qRT-PCR and Western blotting, respectively. The correlation of CRISP2 expressions with sperm morphology, progressive motility and fertility prognosis were analyzed in patients with asthenozoospermia.

RESULTSCRISP2 protein expression was obviously lowered in the ejaculated spermatozoa of patients with asthenozoospermia as compared to the normal volunteers, but no significant difference in CRISP2 mRNA expression was found between the two groups. Correlation analysis showed that CRISP2 protein expression was positively correlated with normal sperm morphology (r=0.6182, P=0.0037) and progressive motility (r=0.6309, P=0.0029). Follow-up study of the patients revealed a higher fertility rate in patients with a relatively high CRISP2 protein expression than in those with low CRISP2 protein expression (80.0% vs 20.0%, P=0.0230).

CONCLUSIONThe expression level of CRISP2 protein is positively correlated with normal sperm morphology and progressive motility. A reduced CRISP2 protein expression indicates poor fertility prognosis of patients with asthenozoospermia, suggesting the potential value of CRISP2 as a novel therapeutic target for treating asthenozoospermia.

OBJECTIVETo observe the effect of activation of Notch1 signaling pathway by Notch intracellular domain (NICD) plasmid transfection on pancreatic cancer cell proliferation and explore the underlying mechanism.

METHODSThe transfection rates were observed under microscope with fluorescence stimulation, and mRNA expression levels of Hes1 were detected by real-time PCR. Cell proliferation changes were evaluated by CCK-8 after NICD and control plasmid transfection in pancreatic cancer cells. Caspase 3 activity was examined using a caspase 3 detection kit.

RESULTSThe transfection rates of NICD plasmid were up to 80% by fluorescence stimulation observation. Hes1 expression was significantly increased after NICD plasmid transfection, suggesting the activation of Notch1 signaling pathway. NICD plasmid transfection significantly promoted cancer cell proliferation compared to control plasmid transfeciton. The activities of caspase 3 were obviously decreased after NICD plasmid transfection in 3 pancreatic cancer cell lines.

CONCLUSIONActivation of Notch1 signaling pathway by NICD plasmid transfection can promote the proliferation of pancreatic cancer cells by inhibiting the apoptosis pathway.
