Objective To investigate the protective effects of isoflurane preconditioning plus mild hypothermia on isolated rat hearts against ischemia-reperfusion (I/R) injury. Methods Fifty male SD rats weighing 250-300 g were randomly divided into 5 groups ( n = 10 each): group Ⅰ control (group C); group Ⅱ I/R; group Ⅲ isoflurane preconditioning (group P); group Ⅳ mild hypothermia (group M) and group Ⅴ isoflurane preconditioning + mild hypothermia (group PM). The animals were anesthetized with intraperitoneal pentobarbital 40 mg/kg. The hearts were immediately removed and perfused with Krebs-Hensleit (K-H) solution aerated with 95% O2 and 5% CO2 at 10 kPa via aorta at 37℃ in a Langendorff apparatus. The hearts were made globally ischemic for 30 min followed by 60 min reperfusion in group Ⅱ-Ⅴ. In group P and PM the hearts were perfused with K-H solution saturated with 1.0% isoflurane for 15 min followed by 15 min washout before ischemia.In group M and PM the hearts were made ischemic at 31 ℃ and perfused at 37℃. LVEDP, LVSP, dp/dtmax,dp/dtmm and HR were measured after equilibration (baseline), immediately before ischemia, and at 30 and 60 min reperfusion. The infarct size and cytochrome C level in cytoplasm and mitochondria of myocytes were measured.Motochondrial ultrastructure was examined using electron microscope. Results Cardiac function was significantly better, the infarct size significantly smaller, the cytochrome C level in cytoplasm significantly lower, while the cytochrome C level in mitochondria of myocytes significantly higher in group Ⅲ-Ⅴ than in group Ⅱ and in group Ⅴ than in group Ⅲ. The cytochrome C level in cytoplasm was significantly lower, while the cytochrome C level in mitochondria of myocytes significantly higher in group Ⅴ than in group Ⅳ. Less damage to mitochondria was observed in group PM than in group I/R, P and M. Conclusion Isoflurane preconditioning combined with mild hypothermia provides better protection against myocardial I/R injury by attenuating the release of cytochrome C from mitochrondria.

Objective To evaluate the perioperative nutritional risk of patients with colorectal cancer. Methods Totally, the nutritional risk of 144 colorectal cancer patients who were newly admitted to our hospital and were radiotherapy-naive or chemotherapy-naive were evaluated using Nutritonal Risk Screening 2002 (NRS2002 ) before operation and two weeks after operation. Meanwhile, hemoglobin, serum levels of albumin and prealbumin, total lymphocyte count were measured and the postoperative complications were observed. Results The incidence of preoperative nutritional risk was 22. 91% (33/144). The predicted incidence of postoperative nutritional risk was 43. 06% (62/144), while the actual incidence was 54. 86% (79/144) (x2 =4. 016, P < 0.05). About 10. 13% of patients whose preoperative nutritional risk score≥3 experienced complications, while only 1. 54% of patients whose preoperative nutritional risk score < 3 had complications (x2 = 3. 065, P < 0.05). Conclusions The perioperative (especially postoperative) nutrition risk is high in patients with colorectal cancer. Patients with higher nutrition risk tend to experience postoperative complications.

Objective To discuss the clinical features, diagnostic methods and treatment of the primary hepatic sarcomas. Methods The clinical data of 4 patients with primary hepatic sarcoma admitted to our hospital from January 1998 to December 2008 were viewed. Results There were 3 males and 1 female with age from 25 to 65 years. Abdominal pain, fatigue, weight loss and mass were among the complains. All 4 cases were misdiagnosed as liver cyst, liver cancer and liver adenoma respectively, and final diagnosis was established only by laparotomy and pathology. They were malignant mesenchymoma, carcinosarcoma, leiomyosarcoma and malignant fibrous histiocytoma respectively. Till now, 3 cases were still alive (respectively 4, 56 and 84 months after surgery), 1 case died intraoperatively. One case recurred 5 years after the operation. Conclusions Primary liver sarcoma is difficult to diagnose. Postoperative pathology and immunohistochemical examination remain the mainstay for final diagnosis. The prognosis is dependent on pathological type, differentiation, tumor invasion and metastasis.

Objective To test the reliability of the Chinese version of tridimensional personality questionnaire(TPQ) and to explore three-dimentional personality characteristics of heroin dependence. Methods Personality characteristics of 358 heroin dependers,114 male smoker and 200 normal controls were investigated using the TPQ. 78 heroin depender were examined 10 days later to test the reliability of TPQ.Results (1) Retest reliabilities of the three higher-order dimensions of the novelty seeking(NS),reward dependence(RD) and harm avoidance(HA) were all good( r =0.87,P <0.01;r =0.84,P <0.01,r =0.64,P <0.01).The dimension's Alpha split of NS or HA were 0.72 and 0.71,respectively. While RD's Alpha split was just 0.29. (2) NS was higher but not significantly in the heroin-dependenc group than normal controls(P =0.09),but the former had significantly higher HA and lower RD [(15.25±5.95) vs (13.22±6.27),t =13.65,P <0.01;(17.08±3.28) vs(18.29±3.83),t =15.07,P <0.01]. (3)There were significantly sex differences in all the three higher-order dimensions of TPQ in the heroin-dependence group( P <0.01). Male heroin dependers had significantly higher NS ,higher HA and lower RD than male controls[(16.99±4.76) vs(15.29±4.60), P =0.002;(14.46±6.01) vs (12.31±6.00),P =0.002],and male heroin dependers had significantly higher NS,lower RD than male smokers( P <0.001).Compared with female controls,female heroin dependers only had significantly higher HA.Conclusion Reliability of the TPQ is good. Sex difference in personality characteristics of heroin depender exits. Male heroin depender have high NS,high HA,and low RD,which can provide scientific data for early intervention of heroin dependence.

Objective: To investigate the clinical characteristics, diagnosis, treatment, and prognostic factors of pancreatic neuroendocrine neoplasms (PNENs). Methods: From August 2004 to August 2016, the clinical data of 63 patients with PNENs in the Sir Run Run Shaw Hospital, an affiliate of the Zhejiang University School of Medicine, were retrospectively analyzed. The data included age, gender, function, tumor location, tumor size, pathological characteristics, lymph nodes, metastasis, and treatment. Association of these factors with PNEN prognosis was proven by univariate analysis and multivariate analysis. Results: In our study, the patients' overall survival time was between 5 and 127 months; the median time was about 46.6 months. Moreover, the survival rates in three years and five years are 88.8％ and 84.1％ respectively. Univariate analysis showed that factors such as lymph node metastasis, liver metastasis, vascular invasion, TNM staging and pathological grading, and radical operation were associated with prognosis (P<0.05). We did not prove any of the factors to be an independent factor associated with poor short-term outcome by multivariate analysis. Conclusion: PNENs are rare low-grade malignant tumors with heterogeneity, which is why they can be erroneously diagnosed. AJCC TNM staging in 2017 and the WHO pathological classification in 2010 can actively guide the prognosis evaluation. The lymph node metastasis, liver metastasis,and vascular invasion affected the prognosis of PNENs. Patients with radical operation had improved prognosis.

Objective To understand the awareness rate of pulmonary tuberculosis(TB) prevention and control among residents in Beijing, so as to provide basis for giving publicity on knowledge of pulmonary tuberculosis prevention and control.Methods Residents in Beijing were randomly selected for questionnaire survey, the main content of questionnaire included The 2006 national survey on knowledge, attitudes and practice about tuberculosis prevention and control, the core knowledge of pulmonary TB prevention and control, as well as the related symptoms of suspected tuberculosis were also included.Results A total of 520 questionnaires were collected, 503 of which were qualified, the effective rate was 96.73%.Among respondents, the total awareness rate of five core knowledge about pulmonary TB prevention and control was 40.87%, 78.93% of the respondents knew that pulmonary TB was a chronic respiratory infectious disease which could seriously damage people's health,48.51% knew that the majority of patients with pulmonary TB could be cured as long as they persisted in correct treatment, only 19.68% knew that examination and treatment of pulmonary TB in the county (district) level TB control institutions could enjoyed national free policy.Nearly 53.48% of respondents knew 4 or more suspected pulmonary TB symptoms, only 7.36% of respondents could recognize all eight symptoms of pulmonary TB.Conclusion Residents in Beijing have low awareness of pulmonary TB prevention and control knowledge.If patients in the early stage of pulmonary TB can not identify symptoms, it is not only delay treatment and increase the spread of tuberculosis, but also induce the transmission of multidrug-resistant Mycobacterium tuberculosis, so produce more challenges to pulmonary TB prevention and control.

Objective The non intrusive ultrasound combined with western medicine in the treatment of chronic prostatitis prostate/research and analysis of the effect of chronic pelvic pain syndrome.Methods96 cases of chronic prostatitis patients who were treated in our hospital from September 2016 to were randomly divided into the observation group, the control group 1 and the control group2.The observation group was treated with western medicine in the treatment of non intrusive prostate ultrasound;1 patients in the control group were given a single non intrusive prostate ultrasound treatment;control group 2 given a single treatment with Chinese and Western medicine.The clinical symptoms and NIH-CPSI scores were evaluated before and after treatment in each group.ResultsComparison between groups of patients before treatment NIH-CPSI score, no significant difference;after treatment, the NIH-CPSI score has decreased, there are obvious differences (P<0.05);the patients in the observation group were decreased significantly, the total score before treatment (26.21±2.20), the total score after treatment (11.77±1.90), there are obvious the difference (P<0.05).The treatment groups were compared with the efficiency, the total efficiency of observation group was 93.75%, the control group of 1 patients with the total effective rate was 75%, the control group of 2 patients with the total effective rate was 68.75%, there was significant difference in the treatment effect, with statistical significance (P<0.05).ConclusionNon intrusive ultrasound combined with western medicine in the treatment of prostate in compared with non intrusive ultrasound therapy and Western medicine alone in the treatment of prostate, has more significant treatment effect, should strengthen the clinical application and promotion.

Objective To examine the surgical treatments for obstructive jaundice caused by bile duct strictures after hepat-ic transcatheter arterial chemoembolization(TACE).Methods Clinical data were retrospectively analyzed of 9 patients who de-veloped bile duct strictures among 229 patients after TACE between June 1994 and March 2011 in People’s Hospital of Zhe-jiang Provincial and the Second Affiliated Hospital of Zhejiang University.There were 6 cases of primary liver cancer,and 3 ca-ses of metastatic liver cancer.Obstructive jaundice occurred 5 to 16 months after TACE treatment.The median time was 8 months.Results All the nine patients with bile duct strictures suffered different degrees of obstructive j aundice,which was cured after surgical operations or PTC + stenting in 7 patients and significantly relieved by percutaneous transhepatic cholangic drainage(PTCD)in 2 ones.Two patients with obstructive j aundice after TACE for primary liver cancer were followed up for 3 years,and no recurrence of hepatic carcinoma and bile duct obstruction was found.The other 7 patients were followed up for 3 to 13 months,and they all died of deterioration of primary disease.Conclusion Patients with obstructive jaundice caused by bile duct strictures after TACE benefit from surgical operations or intervention treatment.Different surgical strategies are selected based on the characteristics of primary disease,the site and extent of bile duct stricture.

Objective To investigate the value of partial hepatectomy in the treatment of hilar cholangiocarcinama( HCC). Methods In this report, 42 patients with hilar cholangiocacinoma treated surgically were analyzed retrospectively. Results Of the 42 patients, 34 cases (81%) underwent surgical resection. In these 34 cases, 15 cases were treated by local resection, 8 cases by a combination of right lobectomy, 3 cases by left lobectomy, 4 cases by left lobectomy and caudate lobectomy, 1 case by left lateral lobectomy and caudate lobectomy, 3 cases by quadrate lobectomy. Curative resection was performed in 25 patients. The median survival rate in patients with curative resection was 28 months, while that with palliative operation was 14 months. The 1-, 2-, and 4-year survival rates of curative resection were 90% , 73% , and 28% , respectively. The 1-, and 2-year survival rates of palliative operation were 57% , and 27%. Conclusion Survival rates in patients with curative resection were better than that of palliative operation. Radical resection in many cases demands a combined liver resection.
