Objective To study The influence and preventive measures for the test results of total bile acid about blood Lipid testing reagent. Methods In Mindray BS -300 automatic biochemical analyzer, we detected total bile acid of the fresh mixed serum separately, then we tested the same samples after the test items of cholesterol, triglycerides, high -density lipoprotein, low - density lipoprotein. Then using fresh serum mixed with normal saline and blood lipid reagent according to 1: 1 dilution ,we measured TBA. We did cross - contamination corrected test (by the anti - cross - contamination to repeat the first step after the test) and recorded all results and had statistics analysis. Results This experiment found that reagents Ⅰ of TC, TG and the reagent Ⅱ of HDL - C , LDL - C had significant positive interference in determination of TBA results. After being corrected by anti - cross - contamination, the results returned to normal. Conclusion When using the automatic biochemical analyzer, we not only acquired the worker fououed of the equipment, and reagents, determined principle, but also pay attention to cross - contamination among reagents, and then in accordance with the equipment work characteristics to establish the appropriate measures to eliminate them, so made sure the reliability of the experimental data to provide clinic with the true objective and actual diagnosis evidence fundamentally.

Objective To learn the emergency response capacity of health authorities at city level in Shandong province in order to discover loopholes and make improvement. Methods The health emergency questionnaire designed by China Health and Family Planning Commission was used for survey of 1 7 city-level health authorities in Shandong province.Results 52.94% of the health authorities were found with health emergency reserve funding; 100.00% of them with public health emergency contingency plans;94.12% of them having health emergency supplies in kind;100.00% of them having health emergency training for all of the staff;100.00% of them with direct web reporting for public health emergency.Conclusion Such authorities were found with satisfactory health emergency capacity in general.Defects were found with emergency funding shortage,poor training and drilling outcomes, poor material reserves management,and insufficient health emergency personnel.

Objective To study the clinical features,treatment methods and clinical outcomes of acute tibialis posterior tendon rupture.Methods Using [(posterior tibial tendon) OR (tibialis posterior tendon)] AND (rupture OR injury OR disruption OR trauma OR tear) as the search words,we searched the PubMed database to retrieve the 19 articles involving 24 cases of acute tibialis posterior tendon rupture.The injury mechanisms,X-ray manifestations,operational findings,treatment methods and clinical outcomes were analyzed.Results The mechanisms of the fracture-related tibialis posterior tendon rupture included motor accident (50.0％,12/24),falling from a height (41.7％,10/24) and sports injury (8.3％,12/24).The tendon rupture was mostly complicated with malleolar fracture (91.7％,22/24),especially the pronation type (70.8％,17/24).Direct suture of the tendon was adopted in 91.7％ of the cases (22/24).Favorable outcomes were achieved in 95.5％ of the cases (21/24).Conclusions Acute tibialis posterior tendon rupture is mostly seen in high-energy medial malleolus fracture.The mechanism of the rupture might be tendon distraction or bone flake incision.Early operation can lead to favorable outcomes.

This study aimed to summarize the diagnosis and treatment of uncommon complications in esophageal and cardiac cancer operations as well as obtain lessons from the failure. Methods:The etiology, clinical diagnosis, treatment, prevention measures, and factors that contribute to the failure of the uncommon complications were analyzed retrospectively. Results: Results showed ten cured cases and eight death cases (except for the reported eight cases). Conclusion:The following conclusions were ob-tained. 1) The complications described in this paper were rare, but they sometimes occur clinically. If wrong treatment was taken, seri-ous consequences would be expected. 2) Once a jet-like bleeding of aortic esophagus avulsion injury occurs, the surgeon must be calm and take proper treatment to successfully patch up the wounds. 3) The right thoracic approach is a new approach to prevent the injury of azygos vein. 4) Patients with anastomotic stoma fistula easily cause a delay in diagnosis if the leakage was wrapped in the inferior phrenic. 5) Taking preventive measures is the key method for the anastomotic aortoesophageal fistula. 6) Occurrence of pulmonary em-bolism after operation should be monitored. 7) Thoracic gastric mediastinal hernia would cause serious consequences if treatment was not taken at a proper time.

Objective To investigate the etiology,diagnosis and treatment of the delayed gastric emptying after abdominal surgery.Methods From January 2005 to December 2012,the clinical data on diagnosis and treatment of 32 cases of delayed gastric emptying after abdominal surgery were retrospectively analyzed.Results Delayed gastric emptying occurred in 32 cases after 5-8 days after the surgery,which accounted for 40.63％ of gastric surgery.Blood loss was 100-300 mL in 15 cases,9 cases' blood loss was more than 350 mL,accounting for 75％.Thirty cases were cured by conservative treatment,accounting for 93.75％,2 cases on the 20th day after surgery and the 31 th day after surgery to accepted surgery again,accounting for 6.25％.Conclusion The delayed gastric emptying after surgery is closely related to surgical site,methods and surgical sub-injury.Non-occurrence of surgical treatment is the main method to cure this disease.

Objective To study the relationship of serum visfatin level and coronary heart disease (CHD). Methods Eighty eight hospitalized patients were enrolled into the study and divided into CHD group(n = 62) and non-CHD control group(n = 26) according to the angiography results; the CHD group was further divided into single-, double-, multi-vessel affected groups. The serum level of visfatin was measured by ELISA,the lesion severity of coronary arteries was assessed by Gensini coronary scoring system, and the correlation between serum visfatin level and coronary lesion severity was evaluated statistically. Results The level of serum visfatin was significantly higher in CHD group than the control group([ 10. 77 ± 2. 63 ] μg/L vs. [ 7. 13 ± 2. 06 ]μg/L,P ＜ 0. 05). The visfatin level increased along with the the number of stenosis vessels(P ＜ 0. 05). The sermn visfatin levels of no stenosis, single-, double-, multi-vessel groups were(7. 13 ± 2. 06) μg/L,(9. 30±2. 19) μg/L,(10. 81 ± 2. 12) μg/L,(12. 79 ± 2. 20) μg/L respectively. A significant positive correlation was found between coronary lesion severity score and serum visfatin level(r = 0. 483, P ＜ 0. 01). Conclusion The visfatin may be directly related to the initiation and development of coronary diseases. The higher level of serum visfatin was, the more severe coronary artery disease would be.
