Objective To evaluate the clinical value of carbon nanoparticles suspension in gallbladder carcinoma lymphadenectomy.Methods 21 cases of gallbladder carcinoma who received radical resection from January 2008 to August 2013 were randomly divided into experimental group (11 cases received carbon nanoparticles injection into the subserosa around the tumor before operation) and control group (10 cases did not receive any tracer).The number of dissected lymph nodes,black-stained lymph nodes and positive lymph nodes were analyzed.Results A total of 138 lymph nodes were resected in experiment group,average 12.546±5.047 lymph nodes per patient,which was significantly more than that in control group in which there were overall 87 lymph nodes,average 8.700±2.497 lymph nodes per patient (t =2.176,P =0.042).The blacken rate of lymph nodes in experimental group was 56.522 ％ (78/138).There were 46 metastasis lymph nodes out of 79 blacken lymph nodes,and the positive rate was significantly higher than that of non-blacken lymph nodes [58.228 ％ (46/79) vs 38.983 ％ (23/59),P=0.039].There was no local or systemic adverse reaction occurred in experimental group.Conclusions Carbon nanoparticles suspension maybe helpful for lymphadenectomy during radical gallbladder carcinoma dissection to reduce operating damage and be safe.

Objective To investigate the clinical effect of low molecular weight heparin (LMWH) and pressure pump on perioperative deep vein thrombosis (DVT) in patients with hip fracture and analyze the effect of LMWH on coagulation function. Methods Retrospective analysis of 95 cases hip fractures patients with clinical data, according to the preventive medication of DVT were divided into LMWH group of 42 cases and LMWH joint pressure pump group of 53 cases. The incidence rate of DVT and the degree of limb swelling after operation in two groups were observed. The differences of blood coagulation function indexes, blood rheology and hip function recovery were compared between the two groups. Results The the incidence rate of DVT in combination group was 1.89% (1 cases ), lower than LMWH group of 14.29% (6 cases )(χ2=5.278,P=0.022). After two weeks' treatment, the difference of anterior thigh circumference and calf circumference in combination group was less than LMWH group (P<0.05). The prothrombin time (PT) and activated partial thromboplastin time (APTT) in two groups post-treatment were lower than those pre-treatment, the D-dimer (D-D) was higher than that pre-treatment(P<0.05), but there was no significant difference between two groups. After 3 months' treatment, the Harris functional independence measure (FIM) in combination group was higher than that in LMWH group (P<0.05). Conclusion LMWH combined with pressure pump could significantly reduce the incidence of perioperative DVT in patients with hip fracture, improve the blood coagulation function and hip function.

The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

Objective To evaluate the feasibility and effect of three-points ablation approach in in treatment of typical atrial flutter guided by CARTO. Methods Twenty-six patients with typical atrial flutter diagnosed by ECG and electrophysiological study (EPS) were enrolled in this study. Activation sequence mapping and linear ablation were performed in 11 patients (conventional group) . Three-points guided linear ablation with CARTO system was performed in another15 patients (three-points group) . Results There was no significant difference in the success rate between the two groups. Both the procedure and fluoroscopic time in three-points group were significantly shorter than that in conventional group [(72.66±29.82) vs (102.52±32.61) min;(4.26±2.76) vs (7.32±3.16) min] . Conclusions The three-points ablations approach is as safe and effective as conventional ablation approach in treatment of typical atrial flutter;however,the former can significantly shorten the procedure time and fluoroscopy time.

AIM: To assess the role of surface free radicals and electromotive voltage of fibrous mineral dusts in rabbit pulmonary alveolar macrophage injuries induced by fibrous mineral dusts. METHODS: Changes in cell death ratio, malandialdehyde (MDA) and cellur electrophoresis ratio, lactate dehydrogenate (LDH)and superoxide dismitase(SOD) activities were determined, the technique of cell culture and Scanning electron Microscopy were used to examine the change of membranous permeability, charge and cellular shape. RESULTS: Fibrous wollastonite and tabulate clinoptilolite, which had no OH-, had no cytotoxicity, while fibrous sepiolite, fibrous palygorskite, fibrous brucite and chrysolite asbestos damaged pulmonary alveolar macrophages in various degrees because of the different OH- levels. All the six fibrous mineral dusts changed the cellular electrophoresis ratio. CONCLUSION: The surface electromotive voltage of fibrous mineral dusts is not an important factor, and the cytotoxicity of them may be related to OH- levels on the mineral dust surface.

In line with the new WHO definition for health and reference of comprehensive health assessments of elderly overseas, the paper screened and set the weight for comprehensive health assessment indicators for military officers, establishing a general health assessment model as a result 402 military officers were subject to Comprehensive Health Assessments, and the outcomes were compared with subjective assessment of experts. The results of both methods are highly coincidental. It proves Comprehensive Health Assessment as a scientific quantitative health assessment method, with promising perspectives in health management in the future.

Objective:To discuss the causes and effective measures of prevention and treatment of chylous fistula after central lymph node dissection (CLND) of thyroid cancer. Methods:A total of 6 127 patients who underwent CLND of thyroid cancer in the Tianjin Medical University Cancer Institute and Hospital between July 2013 and June 2015 were analyzed;of which, 14 patients acquired the complication of postoperative chylous fistula. The following conservative treatments were initially performed:systemic therapy, local pressure bandaging, normal pressure drainage, 50%glucose injection, or pingyangmycin injection through a drainage tube. Surgical op-eration was then conducted when the efficacy of the treatment was poor. Results:After the conservative treatment of the 14 patients, the drainage volume gradually decreased in 12 patients, and surgery was performed on the remaining two patients. Conclusion:The CLND of thyroid cancer must be carefully conducted to prevent postoperative chylous fistula. An active conservative treatment must be the first option when chylous fistula occurs. Surgery must only be performed if the treatment is invalid.

Objective To investigate the influence of two different dose of atorvastatin on the prognosis and endothelial function in post-PCI acute coronary syndrom patients.Methods 92 post-PCI ACS patients were randomly divided into two groups,atorvastatin 20mg and atorvastatin 10 mg group.In each group the patients were treated with atorvasta- tin 20mg or 10mg respectively.After one month we add or decrease the dose of atorvastatin according to the blood lipid level.After 12 month the blood lipid level、FMD、NO、ET、NOS、UAP、AMI were compared between two groups. Results The clinical setting have no significant association between two groups before treating,After treated 1 and 12 month the TC,LDL-C level were significantly decreased as compared with the base level before treating in each group. After treated 1 month,in atorvastatin 20 mg group the TC,LDL-C level were significantly decreased and NO、NO/ET level were significantly higher than those in atorvastatin 10 mg group.During 12 month follow up the incidence of angina pectoris onset and rehospitalization were significantly higher in atorvastatin 10 mg group(P

Objective To investigate the efficacy of dexmedetomidine in preventing postoperative delirium in elderly patients undergoing laparoscopic radical resection for cervical cancer. Methods Eighty American Society of Anesthesiologists physical status Ⅱor Ⅲ patients, aged 65-75 yr, weighing 45-80 kg, scheduled for elective laparoscopic radical resection for cervical cancer, were divided into 2 groups (n= 40 each) using a random number table: dexmedetomidine group (group D) and routine group (group R). Dexmedetomidine was infused at a rate of 0. 5 μg·kg-1 ·h-1 after anesthesia induction until the end of operation in group D, while the equal volume of normal saline was given instead in group R. Delirium rating scale was used to assess the development of delirium within 3 days after operation. Blood samples were collected from the jugular bulb before anesthesia induction (T0 ), at the end of operation (T1 ) and at 1, 6 and 24 h after operation (T2-4 ) to determine the serum concentrations of S100β protein, neuron-spe-cific enolase, tumor necrosis factor-alpha and interleukin-1beta (IL-1β) by enzyme-linked immunosorbent assay. Results Compared with group R, the incidence of postoperative delirium was significantly de-creased (38％∕2％), the serum concentrations of S100β protein, neuron-specific enolase, tumor necrosis factor-alpha and IL-1β were decreased at T1-4 , and the serum concentrations of IL-1β protein were de-creased at T2-4 in group D (P<0. 05). Conclusion Infusing dexmedetomidine at 0. 5 μg·kg-1 ·h-1 from the end of anesthesia induction until the end of operation can effectively prevent the development of delirium following laparoscopic radical resection for cervical cancer, and the mechanism is related to inhibiting in-flammatory responses and reducing brain injury in elderly patients.

With the advancement and development of life science and technology,many problems in liver surgery have been solved,and the surgical procedures of liver surgery have been continuously developed and the indications for surgery have been continuously expanded.Benign and malignant lesions and even donor liver can be performed under laparoscopy.The indications for laparoscopic liver resection are expanding,from superficial liver resection to a wider range of anatomical resection.At the same time of technological advancement,along with the development of the humanistic spirit,liver resection is not only the removal of lesions,but the pursuit of rehabilitation,which is "the best rehabilitation with minimal trauma".Laparoscopic liver resection has been greatly developed due to the spread of the concept of "precise medicine".
