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.

[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

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 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 investigate the relativity of the lupus anticoagulant(LAC), anticadiolipin antibody(aCL) - IgG,aCL-IgM,aCL-IgA levels and clinical symptoms of systemic lupus erythematosus (SLE), and to determine the significance of the LAC level in the prognosis of idiopathic thrombocytopenic purpura (ITP) by detecting the LAC and aCL-IgG, IgM,IgA levels in 310 children with SLE and 249 children with ITP. Methods Kadin-cephalin clotting time(KCCT) and correcting test to detect the plasma LAC level and to the serum aCL- IgG, IgM, IgA levels with enzyme - linked immunosorbent assay. Results In SLE group, there were 66.1% patients with higher LAC among whom 45.9% patients suffered from lupus nephritis , aCL subantibody level elevated in 46.8% patients (90.2% IgG and/or IgM) serum; 46.9% and 11.7% patients suffered from central nervous system diseases and blood diseases with SLE respectively. In ITP group, 36.2% patients with LAC positive were diagnosed as SLE by detecting the serum antinuclear antibody level, and 7.6% suffered from SLE subsequently in the period of 2 months to 2.4 years. Conclusions The LAC and aCL subantibody levels may have an important relativity with the clinical symptoms of SLE. The LAC is the predominant pathologic autoantibody in patients with lupus nephritis, and the aCL subantibody( IgM, IgG) levels were related to lupus thromboangiitis. The IAC level of children with ITP should be monitored in order to determine the prognosis of the disease as soon as possible.

Objective:To evaluate effects of different medication forms of dexmedetomidine on perioperative cognitive function in elderly patients undergoing radical operation of gastric carcinoma, and Ramsay sedation score.Methods:A total of 150 patients aged 65 years and 75 years scheduled for elective radical operation of gastric carcinoma from December 2018 to December 2019 in Shanxi Provincial Cancer Hospital were enrolled, and they were divided into 3 groups according to random number table method: different medication forms of dexmedetomidine groups (group A, group B) and the control group (group C), 50 cases in each group. The patients in group A and group B continued to pump dexmedetomidine at a rate of 0.5 μg·kg -1·h -1 and 0.3 μg·kg -1·h -1 respectively for 15 min before induction of anesthesia. And the patients in group C were given intravenous pumping of an equal volume of 0.9% NaCl for 15 min. Subsequently, patients in group A and group B received continuous intravenous infusion of 0.3 μg·kg -1·h -1 for 30 min before the end of operation, the patients in group C received 0.9% NaCl infusion of equal volume until the end of operation. The cognitive function of the patients was measured by using the Monterey cognitive assessment scale (MoCA) the day before surgery and on day 1,3 and 7 after surgery, and the incidence of perioperative neurocognitive disorder (PND) was counted. Ramsay sedation score at 30 min, 24 h and 48 h after surgery was compared among the three groups. Results:There were 3 patients in group A and 3 patients in group C were excluded because they were transferred to ICU due to serious postoperative complications. There were significant differences in MoCA score among the three groups on day 1, 3, 7 after operation (all P < 0.01); MOCA score of group A, B and C on day 7 after operation was (26.9±0.7) scores, (26.6±1.0) scores, (26.3±1.2) scores, respectively, and the difference between group A and group C was statistically significant ( P < 0.01). The incidence of PND among the three groups on day 1, 3, 7 after surgery had statistically significant differences (all P < 0.05), and the incidence of PND in group A was lower than that in group B and C (all P < 0.05). Ramsay sedation score among the three groups at 30 min and 24 h, 48 h after operation showed statistically significant differences (all P < 0.01), and that in group C was lower than that in group A and group B, and the differences were statistically significant (all P < 0.01). Ramsay sedation score at 24 h after operation in group A was high than that in group B and group C (all P < 0.01). Conclusions:Dexmedetomidine assisted with anesthesia can reduce the incidence of PND in elderly patients undergoing radical operation of gastric carcinoma and enhance the sedative effect. What's more, the most obvious effect is the infusion of 0.5 μg·kg -1·h -1 before anesthesia induction.
