ABSTRACT
Objective:To evaluate the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative cellular immune function in the patients undergoing posterior spinal internal fixation.Methods:Ninety patients, aged 40-70 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective posterior spinal internal fixation in our hospital, were divided into 2 groups ( n=45 each) using a computer-generated table of random numbers: routine group and experiment group.Total intravenous anesthesia was used in routine group, while total intravenous anesthesia combined with TEAS was applied in experiment group.In experiment group, bilateral Zusanli and Sanyinjiao acupoints were stimulated with 2/15 Hz disperse-dense waves at the intensity that could be tolerated by patients at 30 min before induction of anesthesia, maintaining with 2/100 Hz disperse-dense waves from the end of induction until the end of operation at the same stimulation intensity before induction.Bilateral Neiguan and Taichong acupoints were stimulated for 30 min each time with 2/15Hz disperse-dense waves once a day at 1st-4th days after operation.In routine group, the electrodes were connected at the same time period, but no stimulation was given.Venous blood samples were collected before induction of anesthesia, at 1 h after surgery, and on 1st, 3rd, and 5th days after surgery, and the percentage of CD3 + , CD4 + , CD8 + T lymphocytes, CD4 + /CD8 + ratio, WBC count and percentage of neutrophils (NE%) were determined by flow cytometry, and the consumption of intraoperative anesthetics, use of postoperative analgesics, nausea and vomiting, dizziness, infection and length of hospital stay were recorded. Results:Compared with routine group, the total consumption and consumption index of remifentanil were significantly decreased, the percentage of CD3 + T lymphocytes was increased on 3rd and 5th postoperative days, the NE% was decreased on 1st postoperative day, and the incidence of dizziness was decreased ( P<0.05), and no significant change was found in the other indicators in experiment group ( P>0.05). Conclusions:Perioperative TEAS can improve postoperative cellular immune function and has a certain potential value in preventing postoperative infection in the patients undergoing posterior spinal internal fixation.
ABSTRACT
Objective The effect of electronic cigarettes (e-cigarettes) on smoking reduction,cessation and human health remains controversial,meanwhile,studies tocused on e-cigarettes are limited.We conducted this meta-analysis in purpose of helping figuring out the controversy.Methods PubMed, Medline,Embase,Cochrane library,CNKl and Wanfang Databases were searched for articles published up to May 2014.All studies discussing the relationship between e-cigarettes and smoking reduction,smoking cessation or human health were included.The fixed or random-eftect model was used to pool the relative risk(RR).Outcome 4 articles were included based on the inclusion and exclusion criteria,there were totally 7 002 subjects.Meta-analysis indicated that there was significant difference in e-cigarettes and smoking reduction,RR=1.88,95％ CI:1.07-3.32,P=0.09.The Meta-analysis showed that e-cigarettes were available in smoking cessation.RR=1.55,95％ CI:1.24-1.95,P=0.001.Conclusion Tiffs meta-analysis indicated that e-cigarettes were helpful in smoking cessation.Nonetheless,the articles included were too few to credibly support the outcome.Hence,more high-quality,randomized blind and large sample experiments are needed to verify the results.
ABSTRACT
Objective To explore the predictive value of microvessel density(MVD)and blood vessel invasion(BVI)in hepatic metastasis from early-stage rectal cancer.Methods MVD and BVI in the tumor tissue from 380 patients with stage I and II rectal cancer was determined by immunohistochemical S-P method with anti-CDIOS antibody and anti-CD34 antibody,respectively.Multinomial logistic regression was performed to analyze the predictive value of MVD and BVI in hepatic metastasis from early-stage rectal cancer.Results CD105 was expressed in newborn blood vessels,not in normal blood veseels.in the rectal cancer tissue.MVD was correlated with histological type and infiltration depth(P＜0.05).Besides histological type and infiltration depth,BVI was also correlated with histological grade.Multivariate analysis revealed that histological type,tumor infiltration depth,BVI,adjuvant therapy,and MDV were independent predictors of hepatic metastasis from rectal cancer.The risk of hepatic metastasis in patients with postive expression of either MVD or BVI or both were significant higher than that in patients with low expression of MVD and those without BVI expression[hazard ratio(95%CI),4.210(2.182-11.214)].Conclusion BVI and MVD are independent predictors of hepatic metastasis from stage I and II rectal cancer.Combined detection of MVD and BVI may help to predict the clinical outcome of patients with early-stage rectal cancer.
ABSTRACT
Objective To detect the clinical factors related with liver metastasis in young patients with rectal cancer.Methods Three hundred and fifty young patients with rectal cancer were collected to set up the database.Single and multi-factor Logistic regression was applied to indicate the independent factors relating to liver metastasis.The regression equation to predict probability of liver metastasis from rectal cancer was established.Results Liver metastasis was 120 cases (34.3%).Single-factor analysis revealed that patho-organization type,pathologytype,infiltration extent,blood vessel invasion (BVI),TNM stage,operation character,the preoperative level of carcino-embryonic antigen,histology grading were related with liver metastasis.Multi-factor analysis revealed that only BVI (P=0.001),TNM stage (P=0.001),pathoorganization type (P=0.005),the preoperative level of CEA (P=0.008) and operation character (P=0.032) were independent factors to predict probability of liver metastasis.Conclusions Rectal cancer of young patients who being with BVI,advanced phase,high preoperative level of CEA,radical operation or poor differentiation degree,are apt to develop liver metastasis.They should be given further individualized intensive adjuvant treatment.

Ulcer complicated bleeding in 7 cases (33.3%) and perforation in 5 cases (23.8%). Diagnostic rate of preoperative X-ray and gastroscopic examine was 57.1% and 100%, respectively. Of 21 patients 18 (85.7%) were treated by upper partial gastrectomy, and 3 (14.3%) by total gastrectomy. All were not operative death and anastomotic leak.</p><p><b>CONCLUSIONS</b>upper partial gastrectomy can resect focus of ulcer and decrease secretion of stomach acid. It is a simple and ideal pattern of operation for patients with benign ulcer of the gastric cardia.</p>

Objective To evaluate total gastrectomy and regular lymph node dissection for the treatment of advanced cardiac cancer. Methods Three hundred and eighty-seven patients with advanced cardiac cancer underwent total gastrectomy D2+ procedure. The relationships between depth of invasion, lymph node metastasis,the number of metastastic lymph nodes dissected and postoperative survival rate were analyzed. Results The 3-year and 5-year survival rates were 47.3% and 34.2% , respectively. Metastatic rate of N3 lymph node was 4. 8% and 15. 2% in advanced cardiac patients of PT3 and PT4, respectively. Survival rates significantly decreased along with the increase of lymph node metastasis. The 3-year and 5-year survival of patients who had less than 15 lymph nodes dissected was significantly poorer than those who had more than 15 lymph nodes dissected, respectively. The postoperative complication rate and mortality rate of the two groups were 14. 2% and 2. 52% , respectively. Conclution To improve the quality of life and survival rate, D2 + radical total gastrectomy should be performed for advanced cardiac cancer, and when indicated resection of spleen and/or body and tail of the pancreas should be performed.
