In order to provide some useful inspiration for domestic laboratory standardized management of the laboratory records and laboratory reports, it proposed laboratory management recommendations, including emphasizing on the laboratory process records, the integrity of laboratory reports and the correctness of laboratory results, strengthening the laboratory report Remarks functions to increase the added value, cultivating clinical awareness of the clinical tests to enhance communication, and staff attached to the specimen and test data preservation

Objective To compare two types of digestive reconstruction and postoperative complications after total gastrectomy in patients with gastric carcinoma. Methods Roux-en-Y esophagojejunostomy and P-type Roux-en-Y esophagojejunostomy were performed in 50 patients with gastric carcinoma after total gastrectomy. The operating time and postoperative complications were observed. Results The gastrointestinal symptoms for Roux-en-Y esophagojeju-nostomy and P-type Roux-en-Y esophagojejunostomy serve as : diarrhea ( 11.8% and 12.1% ), dumping syndrome (3.9% and 3.3% ) and reflux esophagitis(5.9% and 6.0% ) ,the incidence of the difference was not significant ( than,P>0.05 ). The postoperative complications in P-type Roux-en-Y esophagojejunostomy( 13.1% ) slightly higher that Roux-en-Y esophagojejunostomy( 11.1% ) ,but the difference was not significant( P>0.05 ). Roux-en-Y esoph-agojejunostomy average operative time(3.1±0.3)h was significantly reduced than P-type Roux-en-Y esophagojeju-nostomy(3.7±0.2)h(t=3.35,P<0.05). Conclusion Roux-en-Y esephagojejunostomy and P-type Roux-en-Y esophagojejunostomy is a suitable type after total gastrectomy for patients with gastric carcinoma, but the former opera-tive time was shorter.

Objective To study the relationship between operative procedures and complication of colorectal carcinoma with acute colonic obstruction in the elderly patients. Methods 65 elderly patients undergoing emergency operation for acute colonic obstruction were analyzed retrospectively. One stage tumor resection and anastomosis was performed in 25 cases with right-side colonic lesion and in 26 cases with left-side colonic lesion, Hartmann operation in 8 cases, Dixon operation in 4 cases and proximal colostomy in 2 cases. Results In 65 cases, 13 cases of postopera-tive complications,the rate was 20.0% (13/65) ,which infected with toxic shock two cases,four cases of pulmonary infection,anastomotic leakage two cases, wound infection, split 2 cases, death three cases, the mortality rate was 4.6%. The rates of postoperative complications in right-side colonic lesion, left-side colonic lesion, Hartmann opera-tion and Dixon operation were 69.2% ,0,30.7% and 0 respectively(P < 0.05 ～ 0.01). Conclusion Acute obstruc-tion of colon cancer,the right-side colonic lesion were safe,feasible and few complications in colorectal carcinoma with acute colonic obstruction.

Objective: To compare the incidences of root cracks after canal instrumentation with HyFlex CM system and the ProTaper Universal system .Methods:Sixty mandibular incisors were mounted in resin blocks with simulated periodontal ligaments , and the apex was exposed .The control group of 20 teeth was not prepared , and the other 40 teeth were divided into 2 experimental groups ( n=20 ) .The 40 root canals of the experimental groups were instrumented using HyFlex CM and ProTaper Universal to the major apical foramen ( AF).The horizontal sections 1 mm, 2 mm, and 3 mm from the apex were observed under an optical stereomicroscope at 25 ×magnification .The presence of cracks was noted . Results:No cracks were found in the control teeth .Cracks were found in 1 of 20 ( 5%) teeth in HyFlex CM group , and 17 of 20 ( 85%) teeth in ProTaper Universal group .The difference between the two experimental groups was statistically significant (P<0.01).Conclusion: The HyFlex CM files caused fewer root cracks than the ProTaper Universal files during the root canal instrumentation .

Objective To investigate the degree of health knowledge and needs for health education of urban and rural inhabitants in Tianjin, and to study strategy of health education and health promotion in community. Methods Using a questionnaire survey, 900 inhabitants were investigated on their health knowledge, behavior, access to knowledge, and health education needs. Results The rate of health knowledge awareness was 65.63%, the rate of health promotion was 67.05%. Logistic regression results showed that the education background level (OR=1.323, 95%CI=1.113～1.573) and income per capita monthly(1.607, 1.317～1.962)were the influential factors for the rate of health knowledge awareness (P

Objective To evaluate the value of real time continuous blood glucose monitoring system (RT-CGMS) versus intermittent blood glucose monitoring (IGM) in the critically ill patients under intensive insulin therapy (IIT).Methods A systematic searching randomized and controlled trials (RCT) in databases was performed for meta-analysis by Review Manager 5.2 software.Outcomes were hypoglycemia episode,alteration of mean blood glucose level,the percentage of time at a blood glucose level within optimal target range,and the early mortalities.Results Six studies,totally 531 patients,were included in this meta-analysis.The pooled SMD of mean blood glucose level was =-0.21 (95％ SMD:-0.43-0.01,P=0.07).The pooled SMD of percentage of time at a blood glucose level within optimal target range was 0.20 (95％ SMD:-0.09-0.49,P =0.18).The pooled OR of hypoglycemia episode frequency was 0.20 (95％ CI:0.09-0.43,P ＜ 0.01).The pooled OR of early mortalities was 0.35 (95％ CI:0.14-0.89,P =O.03).Conclusions In critically ill patients under the intensive insulin therapy,RT-CGMS had obvious beneficial effect on reducing hypoglycemic events.RT-CGMS had no obvious beneficial effect on keeping blood glucose level within optimal target range.

Objective To investigate the impact of the COX-2 specific inhibitor parecoxib on postoperative serum cytokines and early cognitive function in the elderly patients undergoing knee replacement.Methods Seventy-two elderly patients undergoing knee replacement were divided into a control group (group Ⅰ)and parecoxib group (group Ⅱ).MMSE score were compared at preoperative 1 d and postoperative 1 d,3 d,7 d.Before induction of anesthesia (T1 ),postoperative 6 h (T2 ),1 d (T3 ),3 d (T4 ),7 d (T5 ),the serum IL-1β,IL-6 concentrations were measured,meanwhile the serum S-100βwere measured in T2 .Results At postop-erative 1 d,3 d,the MMSE score in group Ⅰ was significantly lower compared with the preoperative (P <0.05).IL-6 in T2 ,IL-1βin T3 increased in both group.In group Ⅱ,three days later,the exaltation of plasma inflammatory factors returned to the preopera-tive level,but this process last untill T5 in group Ⅰ.The plasma concentration of IL-6 in T2 ,T3 ,T4 and IL-1βin T3 ,T4 in group Ⅰwere higher than group II (P <0.05).At T2 ,the serum S-100βin group Ⅰ was (1 625 ± 364)pg/mL higher than group Ⅱ(1 263 ±174)pg/mL(P <0.05).Conclusion The protective effection of COX-2-specific inhibitor parecoxib upon postoperative cognitive decline in elderly patients undergoing orthopedic surgery may be related to inhibition of peripheral cytokine release.

Objective To testify the lung injury induced by cardiopulmonary bypass(CPB) in canine model and observe the influence of CPB on the aquaporin-1 ( AQP1 ) mRNA expression in canine lung. Methods 8 mongrel dogs were used to perform the cardiopulmonary bypass. The hearts arrested for 90 minutes with mild hypothermia and rebeated for 6 hours. The hemodynamics, the ratio of lung dry weight and wet weight, the plasmic osmotic pressure, and the characteristics of light and fine structure were analyzed. The retro-transcription polyase chain reaction ( RT-PCR ) was used to measure the expression of AQP1 mRNA during the CPB. Results The hemodynamic data were stable in different time point during the CPB (P ＞0.05 ). The ratio of lung dry weight and wet weight was getting lower ( P ＜0.001) and the plasmic osmotic pressure was getting higher due to the prolongation of the CPB time and reperfusion time ( P ＜0.01). The light and electron microscopy showed the prominent aggregation of the white blood cell, severe interstitial edema and mild tear of respiratory membrane after 3 hour and 6-hour rebeat. AQP1 mRNA expression in lung was downregulated, 78.4% after 3-hour reperfusion and 55.5% after 6-hour reperfusion respectively, comparing to the level before CPB. Conclusion We recognize that the lung injury and lung edema were severe following 3-hour and 6-hour rebeat in CPB and hypothesize that the down-regulation of lung AQP1 mRNA expression may be a sign of pulmonary interstitial capillary injury induced by CPB.
