Objective To investigate the risk factors for deep vein thrombosis (DVT) of lower limbs after laparoscopic surgery.Methods A total of 230 patients underwent laparoscopic surgery were selected in Huanggang Central Hospital from January 2014 to August 2016.The patients were divided into DVT group and non-DVT group according to DVT of the lower limbs,and the related risk factors for DVT of lower limbs after laparoscopic surgery were analyzed.Results In the 230 patients,there were 10 patients with DVT of lower limbs and 220 patients without DVT of lower limbs,the incidence of DVT of lower limbs was 4.35％ (10/230).Logistic regression analysis showed that age ≥40 years old,operation time ≥120 min,postoperative ambulation time ≥ 30 h,the intraoperative position of high-head and low-foot,plasma D-Dimer level ≥0.5 mg · L-1 were the independent risk factors for DVT of lower limbs after laparoscopic surgery (P ＜ 0.05).Conclusion There is a certain incidence of DVT of the lower limbs after laparoscopic surgery.The effective prevention measures should be taken to reduce the incidence of DVT after laparoscopic surgery according to the related factors of DVT.

Background Cytokines play a crucial role in mediating immune tolerance or immune rejection of corneal transplantation.However,the study on the expression of cytokines in corneal graft is seldom.ObjectiveThe purpose of the study is to investigate the change of cytokine expression in allografts at different time points after corneal transplantation.Methods BALB/c and C57BL/6 mice aged 6 to 8-week old were used to establish autologous and allografts keratoplasty models.BALB/c mouse was use as donor and receipt in autologous group,and the cornea of C57BL/6 mouse was used to graft on the BALB/c mouse in the allografts group.The graft inflammation was clinically scored,and graft inflammatory scores of ≥5 or opaciflcation scores of ≥2 were identified as rejection.BALB/c mice were randomized into normal control group(3 mice)and allografts group(15 mice).Reverse transcriptPCR (RT-PCR) was used to detect the expression of interleukin-4 (IL-4) mRNA,interferon-γ (IFN-γ) mRNA,IL-10mRNA and tumor necrosis factor(TNF-α) mRNA in graft 6 hours and 1 day,3,7,14 days after operation.Results The corneal graft opacification score was ＜2 and inflammatory score was ＜5 in the 10 mice with autologous keratoplasty until 60 days with the survival rate 100％.The edema,opacification and new blood vessel were seen in the BALB/c mice received allografts keratoplasty.The inflammatory score was ≥ 5 and the opacification score was ≥2 24 days after surgery with the rejection rate 100％,in the allografts group,and the graft survival time was (17.80±4.66)days.RT-PCR showed that IL-4 and IFN-γ were positively expressed,and IL-10 and TNF-α were absently expressed in normal mouse cornea.In the allografts keratoplasty mice,positive responses for IL-4,IFN-γ and IL-10 were found in 6hours after operation,but TNF-α was absent.From 1 day through 3 days after operation,the expressions of IL-4,IFN-γand TNF-α were enhanced but IL-10 was disappeared in the graft.IL-10,IFN-γ and TNF-α were expressed till the 7th day,but on the 14th day,only IL-10 was detected in graft in the allografts keratoplasty mice.Conclusions TNF-αis a main factor among the variety of cytokines that may influent corneal allograft rejection locally.

[Objective]To evaluate the clinical application and results of the anterolateral acromial approach with minimal incision in the treatment of proximal humerus fracture.[Method]From December 2006 to December 2008,42 patients with proximal humeral fracture were treated by the anterorlateral acromial approach using locking plate.There were 25 males and 17 females.All the fractures were classified with AO/OTA classification.There were 5 A2-fractures,11A3-fractures,7 B1-fractures,12 B2-fractures,3 C1-fractures,4 C2-fractures.Anterolateral acromial approach with minimal incision was applied and the deltoid muscle was seperated to expose the fracture fragments.Under direct vision the direct and indirect reduction of the fractures were performed.The locking plate was inserted distally beneath the deltoid muscle and between the distal plate and the humeral shaft was adjusted through another small skin incision on the lateral upper arm.Locking screws were inserted to the proximal and distal plate.Operation time,incision length,blood loss,reduction,Neer scores at 1 year were analyzed in different time points.[Result]All the cases were completed with minimal incision.There were significant differences(P

Objective To evaluate the diagnostic accuracy of ultrasound miniature probe(UMP)examination in tumor invasion(T staging) and local lymphatic node metastasis(N staging) for colorectal carcinoma. Methods Preoperative UMP examinations(12 MHz) were performed on 53 patients with colorectal carcinoma undergoing surgeries.The diagnosis accuracy of UMP examination in T and N staging was determined by comparison of the results of operation exploration and histopathologic findings. Results The accuracy in T staging for colorectal carcinoma was 86% with UMP examination,and that for early stage colorectal carcinoma was 100%.The accuracy,sensitivity and specificity in N staging for colorectal carcinoma were 81%,77%,and 84%,respectively with UMP examination. Conclusion UMP examination works well in determining T stage of colorectal carcinoma,especially for early stage colorectal carcinoma and those with tumor stenosis.

Objective To determine the inhibitive effect of interferon-a on hepatic metastasis of colon cancer. Methods Metastatic model of human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into the colon wall of nude mice.The mice were randomly divided into 4 groups:(1)Control group(receiving saline solution only);(2)5-FU treatment group;(3) IFN-?-2b treatment group;and(4)5-FU combined with IFN-?-2b treatment group(combined group). 5-FU and IFN-?-2b were given via peritoneum injection 1 time/2 days for eight weeks.The mice were killed at nine weeks.The tumors were weighed,the microvessel density(MVD) was detected,and the liver was examined histologically in order to discover the micrometastasis. Results In control group, 5-FU group,IFN-2b group and combined group,the tumor weight was(1.53?0.78)g,(0.87?0.59)g,(0.81?0.43)g and ( 0.23?0.09)g, respectively;the tumor inhibition rate was 0,43.1%,47.1% and 84.9%, respectively;the hepatic metastasis rate was 85.7%,78.6%,21.4% and 0 respectively.MVD in IFN-? group and combined group was significant lower than that in control group and 5-FU group. Conclusions IFN-? can inhibit the growth and hepatic metastasis of orthotopic implanted human colon cancer by inhibiting the tumor angiogenesis.It may be more effective when INF-? combined with cyotoxic agents.

Aim To investigate the protective effect of non-mitogenic human acidic fibroblast growth factor (nm-haFGF) on cerebral ischemia-reperfusion injury in mice. Methods Cerebral ischemia-reperfusion model was made by ligating bilateral carotid for 20 minutes in mice. These mice were randomly divided into model group( iv NS), two doses of nm-haFGF (iv 25、50 ?g?kg-1) groups, rhaFGF group(iv 50 ?g?kg-1) and sham- operated group. Step down test and Y-type electric maze were used to examine the effect of nm-haFGF on learning and memory of mice, then Even′s Blue(EB) level and NO level in brain of these mice were measured. Results The nm-haFGF significantly decreased numbers of errors of mice in 5 min in step down test and in Y-type electric maze test; EB and NO levels in brain of these mice were lower than those of model group respectively. Conclusion The nm-haFGF can protect cerebral ischemia-reperfusion injury in mice.
