Objective To investigate the etiology and prevention of venous thrombosis (VT) following laparoscopic cholecystectomy (LC). Methods A retrospective analysis on clinical records of 12 cases of VT following 258 cases of LC in this hospital from January 2002 to June 2004 was carried out. Results [WTBZ]The operation time was 17~58 min (mean, 38 min), and the intraoperative blood loss was 15~100 ml (mean, 45 ml). In 11 cases of superficial vein thrombosis, on a treatment for 6~8 days the symptoms of redness, swelling, heat, and pain vanished. Re-examinations of color Doppler ultrasonography revealed disappearance of thrombosis, and an anticoagulation therapy with Warfarin was given. Follow-ups for 6~12 months found no recurrence. In 1 case of deep femoral vein thrombosis accompanying pulmonary embolism, an anticoagulation therapy was employed for 4 months and a follow-up for 6 months showed no recurrence. Conclusions The development of VT following LC is correlated to patients' high-risk factors, carbon dioxide pneumoperitoneum, and anesthesia administration. Emphasis should be on active countermeasures during peri-operative period.

Human Y chromosome contains sex determining region and the genes associated with spermatogenesis.Genomics of the human Y-chromosome association with male infertility appeared and new exploration for male infertility was formed.Though the genes of Y chromosome lack of meiotic recombination,Y chromosome did not disappear,but also it is being in evolution.It includes several families of satellite sequences and the alphoid repeats,Alu repeats associated with male infertility.A total of 107 genes were listed in the database in Y chromosome.The male specific region on Y(MSY) harbours 156 transcription units of which half(78) are suspected to encode proteins,27 protein or protein families identified,11 protein only expressed in the testis associated with spermatogenesis.It is likely that the genes on Y chromosome play an important role not only on spermatogenesis,but also on prostate,brain or other organs.

Fifteen min after adding nimodipine 50 ?mol/L, the contractility of the left atrial muscle decreased from 100 % of control to 55.5 +4.2 o/o and its inhibitory effect was equal to the effect of verapamil (25 ?mol/L ) . Nim at the same concentration inhibited strongly the positive staircase phenomenon but could not reverse it into the negative staircase phenomenon as verapamil 25 ?mol/L did. The same concentration of Nim suppressed significantly the post rest contraction. On the contrary, the post rest contraction was not affected by verapamil at 25 ?mol/L. In addition, Nim 50 ?mol/L reversed or prevented significantly the ouabain-induced arrhythmias in isolated left atria. These results suggest that the negative ino-trbpism of Nim may be related not only to the inhibition of Ca2 + influx to the cells and also to the decrease of the intercellular Ca2+ release and that Nim might present the possibility in treating arrhythmias or other heart disease

BACKGROUND: When the liver affected severe damage or excalation, liver stem cells rapidly proliferated and differentiated into mature liver cells to repair liver tissue. However, liver regeneration is a complicated multiple signal molecular regulatory process and related genes and proteins that participated in regulation remain unclear. OBJECTIVE: To investigate the expressions of CD34 and Delta-like-1 protein in rat liver regenerated tissues after partial hepatectomy. METHODS: Rat hepatic regeneration models were established after hepatectomy. Expressions of ATPase, proliferating cell nuclear antigen (PCNA), CD34 and Delta-like-1 protein were detected by hematoxylin-eosin staining, enzyme-histochemistry and immunohistochemistry method at various time points. RESULTS AND CONCLUSION: At the early stage of liver regeneration, the expression of ATPase was down-regulated, and the expressions of CD34 and Delta-like-1 protein were up-regulated. At the middle stage, the expression of ATPase was increased to the normal level, and the expressions of CD34 and Delta-like-1 protein were down-regulated. The expression of PCNA protein was continuously up-regulated. These suggest that the expressions of ATPase, CD34 and Delta-like-1 protein were different at different stages of hepatic regeneration, which means that different signal molecules were cooperated during the hepatic regeneration, and Notch-Delta signal pathway takes part in the pathogenesy.

Purpose: The aim of the present study was to investigate the expression of breast cancer resistance protein (BCRP) in primary breast carcinoma and to determine whether such expression can predict survival. Methods: Expression of BCRP in 60 breast cancer patients was determined by immunohistochemistry on formalin-fixed, paraffin-embedded tumor section. The relationship between the expression of BCRP with the clinicphathological characteristics and the prognosis of breast cancer patients were also analyzed. Results: ①BCRP expression was observed in 21 of 60 (35%) cases.② BCRP expression was more frequently observed in patients with lymph node metastasis or hormone receptor (P 0. 05) .③Kaplan-Meier analyses revealed that BCRP expression associated only with disease-free survival (DFS) (P 0. 05) . ④In univariate and multivariate Cox regression analyses, tumor size, lymph node metastasis and estrogen receptor (ER) was associated with DFS and OS (P

One-and-a-half syndrome with facial diplegia, also referred to as the fifteen-and-a-half syndrome, is an extremely rare clinical entity caused by involvement of bilateral tegmentum of pons. Herein, we report a 52-year-old male who presented with one-and-a-half syndrome with left facial paralysis, which was consistent with the so-called eight-and-a-half syndrome. Brain magnetic resonance imaging showed pontine infarction. Five days after initiation of antiplatelet therapy, the patient developed right facial paralysis, a diagnosis of fifteen-and-a-half syndrome was made, repeat MR imaging revealed bilateral pontine tegmentum infarction. Fifteen-and-a-half syndrome is a newly proposed concept associated with pontine infarction. The clinicoradiological features of this specific disease are as yet unclear due to its extreme rarity. The current case would help advance the current understanding of the disease spectrum of pontine infarction.

In this article routine treatment and neck acupuncture were used in 95 cases with acutecerebral embolism. The results show that the evaluation of mark with Neurological Function Distress is remarkedly reduced,and cure rate and general effective rate are more higher than routine treatment (contrast,P<0.01) .This study suggests that neck acupuncture is a simple and effective theapy of cerebral embolism.

We developed the monoclonal antibodies against nucleoprotein (NP) of Newcastle disease virus (NDV),and established a double antibody sandwich ELISA method for quantitative determination of NP antigen of NDV (NDV NP ELISA).The recombination NP protein derived from strain F48E9 of NDV were prepared and used to immunize BLAB/c mice.The mouse splenic cells from immunized mice were fused with SP2/0 cells to generate monoclonal antibodies (mAb).The NDV NP specific mAbs were paired to establish a double antibody sandwich ELISA method.The performance of the NDV NP ELISA was evaluated,including specificity,sensitivity,precision,accuracy and linearity.The correlation between the ELISA and PFU virus titer was analyzed by regression analysis method.Two monoclonal antibodies 3C10 and 4E7 were selected to establish double antibody sandwich ELISA for NP antigen of NDV.The linearity and performance of the NDV NP ELISA was characterized.The detection linearity fell in the range of 0.015-0.250 μg/mL (R2 =0.997 4).The detection limit of the assay was 0.015 μg/mL.The recovery was between 88.4％ and 106.01％;the variation coefficient was below 3.4％.In testing of 50 NDV virus samples,this assay performed well and correlated comparably with PFU virus titer (R2 =0.920 9).The NDV NP ELISA for quantitative detection of NDV is a reliable quantifiable assay for detection of NDV NP protein;it provides a new approach for rapid and quantitative detection of Newcastle disease virus.

Objective To study the role of cover-stent and embolization in the treatment of hepatic artery pseudoaneurysm following liver transplantation.Methods 5 patients with hepatic artery pseudoaneurysm after liver transplantation were treated with cover-stent and embolization between May 2010 and July 2013.The clinical features,imaging findings and complications were reviewed.Results All the 5 patients with hepatic artery pseudoaneurysm were successfully treated.2 patients with intrahepatic pseudoaneurysm received embolization.Of the 3 patients with extrahepatic pseudoaneurysm,2 received cover-stent treatment,and 1 patient received embolization.No complications related to the interventional treatment were encountered.2 patients died from multi-organ failure one month after the interventional treatment.Conclusion Cover-stent and embolization were effective and safe to treat patients with hepatic artery pseudoneurysm following liver transplantations.

Objective To study the effect of Dachengqi decoction on expression of triggering receptor on myeloid cell 1(TREM-1)in septic rats in order to further provide a theoretical basis concerning the mechanism of this decoction for treatment of sepsis. Methods 100 male Sprague-Dawley(SD)rats were randomly divided into five groups:normal control,sham operation,sepsis model,low-dose and high-dose Dachengqi decoction groups (each,n=20). The sepsis models were reproduced by cecal ligated perforation(CLP). The low-dose and high-dose Dachengqi decoction groups were lavaged separately by low dose(5 mL/kg)and normal dose(10 mL/kg)Dachengqi decoction at 2 hours before CLP and after CLP twice per day(interval 8 hours),and the other three groups were lavaged with 10 mL/kg normal saline. Five rats in each group were killed randomly at the time points of 6,12,24,48 hours after CLP;the abdominal aorta blood and the liver tissue were collected. The plasma levels of TREM-1,interleukin-6 (IL-6),tumor necrosis factor-α(TNF-α)were tested by enzyme linked immunosorbent assay(ELISA). The expression level of TREM-1 mRNA in the liver was measured by reverse transcription - polymerase chain reaction (RT-PCR). Results Compared with normal control group and sham operation group, the plasma levels of TREM-1, IL-6, TNF-α and the expression of liver TREM-1 mRNA were increased significantly in model group. Compared with model group,the above indexes in low-dose and high-dose Dachengqi decoction groups were reduced obviously,the changes being more marked in the high-dose group;the levels of TREM-1,IL-6 at 6 hours after operation and the levels of TNF-αand TREM-1 mRNA at 24 hours after operation in high-dose group were lower than those of low-dose group〔6 hours TREM-1(ng/L):179.19±4.43 vs. 213.86±2.84,6 hours IL-6 (ng/L):136.80±7.70 vs. 162.90±3.87;24 hours TNF-α(ng/L):71.61±5.07 vs. 108.53±6.29,24 hours TREM-1 mRNA:24.33±3.16 vs. 27.22±3.34,all P<0.05〕. Conclusion The partial mechanism of the efficacy of Dachengqi decoction for treatment of sepsis was probably related to the inhibition of TREM-1 expression.
