Objective:To discuss the role of incision for short-term outcomes of simultaneous resection in synchronous colorec-tal liver metastases (sCRLM). Methods:We reviewed the data of 37 patients who underwent simultaneous resection between January 2009 and December 2014 in our department and compared the short-term outcomes between Mercedes and midline incisions. Results:Mercedes and midline incisions were used in 19 and 18 patients, respectively. The two groups showed similarities in patient characteris-tics, major hepatectomy, surgery time, blood loss, and hilar block time. The midline group comprised more rectal cancer patients (P<0.001). The two groups did not differ significantly in complication incidence (47.4%vs. 16.7%, P=0.08) and postoperative stay time (22.1 ± 9.5 d vs. 17.2 ± 6.7 d, P=0.08). At body mass index (BMI)<25, the complication incidence (P=0.046) and postoperative stay time (P=0.051) were lower in the midline group than in the Mercedes group. Conclusion:Midline incision provided similar exposure in simultaneous resection for sCRLM and was better than Mercedes incision in rectal cancer patients. Patients with midline incision may attain better short-term outcomes if BMI is<25.

Objective To evaluate the relationship of metabolic syndrome (MS) and MS components with thyroid nodule. Methods A total of 10 357 subjects ( age ＞ 18 years old) who received physical checkup at the Second Affiliated Hospital of Dalian Medical University between June 2009 and June 2010 were enrolled in this retrospective study. Anthropometric parameter, fasting plasma glucose (FPG),serum lipid profile, blood uric acid, alanine aminotransferase and thyroid ultrasonography were measured. Results The prevalence of thyroid nodule,MS,and thyroid nodule + MS was 46. 96% ,23. 6%,and 11.6%, respectively. The prevalence of thyroid nodule was significantly higher in MS patients than in non MS patients ( 75.9% vs 38. 0%, P ＜ 0. 05 ). Multifactor logistic analysis showed that MS, body mass index (BMI) and FBG (β vales were 0. 78,1.22,and 0. 62,respectively; odds ratios were 4. 167,3. 876,and 2. 359, respectively; all P ＜ 0. 05 ) were independently correlated with the development of thyroid nodule. Conclusions Significantly increased prevalence of thyroid nodule could be found in MS patients. BMI and FBG may be independent risk factors of thyroid nodule.

Objective To determine the relationship between normal weight obesity (NOW) and cardiovascular risk factors.MethodsA total of 940 adults who received a health examination in out hospital were recruited in a cross-sectional study,and 407 with a body mass index (BMI) of18.5 to 25 kg/m2were enrolled for further analysis.Body fat percentage ( BF％ ) was measured by bioelectrical impedance analysis (BIA),and the subjects were assigned to the NOW group ( BF％ ≥25％ for male or BF％ ≥35％for female) or the control group ( BF％ ＜ 25％ for male or BF％ ＜ 35％ for female).Cardiovascular risk factors and their detection rates were compared between the two groups by using independent sample t test and x2 test.The correlationbetweenNOW and cardiovascular risk factors was assessedbylogistic regression.Results The prevalence of NOW in men and women were13.1％ and14.9％,respectively.The prevalence of NOW was increased with age ( x2 =6.90,P ＜0.05 ).Systolic blood pressure (SBP),diastolic blood pressure ( DBP ),total cholesterol ( TC ),triglycerides ( TG ),low-density lipoprotein cholesterol ( LDL-C) and serum uric acid (SUA) were significantly increased in the NOW group (t values were 2.97,2.44,2.54,5.09,2.71and 3.91,respectively; all P ＜ 0.05 ) ; whereas high-density lipoprotein cholesterol ( HDL-C) was significantly decreased in the NOW group (t =-3.90,P ＜ 0.05 ).The prevalence of hypertension,hyperglycemia,high triglyceride,low HDL-C,dyslipidmia and hyperuricemia was increased in the NOW group in comparison with the control group ( x2 values were 6.76,5.58,14.50,11.97,10.97 and 8.76,respectively;allP＜ 0.05 ).LogisticregressionshowedNOWincreasedtheriskof hypertension,hyperglycemia,dyslipidmia or hyperuricemia by 2.186,2.120,2.088 or 4.175 times.After adjustment for age and gender,the risk for hyperuricemia was decreased to 3.491,but remained statistically significant higher.Conclusions NOW may be correlated with cardiovascular risk factors,and those with NOW could be at higher risk for cardiovascular diseases.

The level of serum soluble interleukin-2 receptor(sIL-2R)was measured in 103 patientswith hepatitis B and 26 hepatitis B virus(HBV)carriers by enzyme-linked assay.The sIL-2Rconcentration were elevated significantly in each type of hepatitis B patients and HBV carriers,compared with control group(P

ObjectiveTo investigate the concentration of water fluoride and the application of water defluoridation projects in Suizhou,and to provide a basis for water improvement and prevention of the disease.MethodsCross-sectional study was carried out to investigate completely the water defluoridation projects built between 1986 and 2009 in the area under Suizhou's jurisdiction; 3 source water and terminal water samples of the projects in use were collected,respectively; 1 water sample was collected,respectively in the 3 projects with out-ofcommission or discarded water sources that used to be major water supply,for detection of fluoride,chloride,total hardness,heavy metals and other indicators.ResultsA total of 21 projects were investigated,14 projects were in normal use (66.7％),7 projects were out of order and abandoned (33.3％).Of the 14 projects normally used,13projects with water fluoride concentration ≤ 1.0 mg/L(92.9％)and 1 project with water fluoride concentration higher than 1.0 mg/L(7.1％),the concentration of water fluoride in the 7 abandoned projects was higher than 1.0 mg/L(100％).Arsenic and lead levels of all the water samples were normal.There were two water samples with iron content exceeded the standard,and one total hardness of water samples exceeded the standard in the normally used 14 peripheral water sources.One chloride content exceeded the standard,one manganese content exceeded the standard,two iron content exceeded the standard and three total hardness exceeded the standard in the seven abandoned projects.ConclusionsSome defluoridation projects are stopped using and abandoned in Suizhou,and the water fluoride exceeds the standard.

Objective To study the clinicopathologic features of brain tumors in patients with medically intractable epilepsy. Methods The clinical, radiologic and pathologic features of brain tumors in thirty-six patients with intractable epilepsy encountered during the period from 2008 to 2014 in the Epilepsy Center of Haidian Hospital were retrospectively reviewed. Results There were 18 males and 18 females in thirty-six patients. The mean age of seizure onset and disease duration were (14.05 ± 1.67) years and (10.04 ± 1.19) years respectively. The histological types of brain tumors included ganglioglioma (12/36, WHO gradeⅠ,1/36, WHO gradeⅡ), dysembryeplastic neuroepithelial tumor (2/36, WHO gradeⅠ), pleomorphic xanthoastrocytoma (1/36, WHO gradeⅡ), angiocentric glioma (1/36, WHO gradeⅠ), astrocytoma (4/36, WHO gradeⅡ), oligoastrocytoma (1/36, WHO gradeⅡ, 2/36, WHO gradeⅠ-Ⅱ), oligodendroglioma (1/36, WHO gradeⅠ-Ⅱ,1/36, WHO grade Ⅱ), cavernous hemangioma (4/36) and Sturge-Weber syndrome (1/36). Most of these tumors were located in temporal lobe (25/36, 69.4%). Patients were followed up for 0.5-7 years after operation. One patient was lost for follow up. Seizure outcome after the epilepsy operation revealed that 28 patients (77.8%) had Engel gradeⅠ, 4 patients (11.1%) had Engel gradeⅡ,2 patients (5.6%) had Engel gradeⅢ,1 patient (2.8%) had Engel gradeⅣ. Conclusion Brain tumors in patients with medically intractable epilepsy are almost low grade tumors of the nervous system. Focal cortical dysplasia is existed in most brain tissues from the epilepsy operation. Low grade tumors of the nervous system have close relation with focal cortical dysplasia in patients with medically intractable epilepsy. It is possible that the classifications of pathology diagnosis has connection with prognosis.

BACKGROUND: During spinal orthopedic repair, the main difficulty is to maximize the correction of the deformity, simultaneously, to reduce the incidence of trauma and complications, especial y to avoid the corresponding spinal nerve injury. OBJECTIVE: To evaluate the curative effect of one-stage posterior pedicle subtraction osteotomy of apical vertebra with transpedicular instrumentation in the treatment of rigid angular kyphosis of thoracolumbar spine. METHODS: We retrospectively analyzed the data of 42 cases of rigid angular kyphosis of thoracolumbar spine that were treated by one-stage posterior pedicle subtraction osteotomy of apical vertebra with transpedicular instrumentation. Al patients received detailed imaging examination before and after operation. Kyphosis angle, Frankel grading and perioperative complications were recorded in al patients. X-ray films or CT films showed the bone graft fusion during fol ow-up. RESULTS AND CONCLUSION: Patients were fol owed up for 10-36 months after treatment. The average time of bone graft fusion was 5.1 months. Cobb’s angle of kyphosis was corrected from 78.4° (38°-110°) preoperatively to 7°(-8°-24°) at 10 days after treatment. The correction rate was 90%. The average angle during final fol ow-up was 7.9°, with an average loss of 0.9°. In 16 paresis patients, Frankel grading results showed grade B in 0 case, grade C in 3 cases, grade D in 5 cases, and grade E in 8 cases during final fol ow-up, showing significant improvement as compared with that pre-treatment (P < 0.05). Among 42 patients, 5 cases had complications. At 7 months after treatment, there were screw and titanium rod loosening at the distal end of the fusion segment in 1 case, cerebrospinal fluid leakage in 2 cases, transient double lower limb weakness in 1 case, pain in one side of lower limb in 1 case, and no severe complications appeared. These results verified that one-stage posterior pedicle subtraction osteotomy of apical vertebra with transpedicular instrumentation could achieve satisfactory clinical outcomes in rigid angular kyphosis of thoracolumbar spine. The internal fixation was stable and with a high fusion rate and few complications. The medium-term effect was satisfactory.
