ObjectiveTo evaluate the effect of psychological and behavioral intervention combined with varenicline smoking cessation clinics and to analyze predictors of successful quitting.Methods Subjects were collected from quitters who went to receive consultation and intervention in “smoking and related diseases” clinic at Zhongshan Hospital,Fudan University from March 2009 to September 2010.Eligible subjects were screened and divided into strengthen follow-up group and control group.The 4 weeks continuous abstinence rate from week 9 through week 12 were observed logistic regression model and used to analyze the predictors of successful quitting.Results Subjects who are addicted to nicotine received strengthening psychological and behavioral intervention combined with varenicline in smoking cessation clinics.The total continuous cessation rate during the 9th-12th week was 52.3％,with 60.9％ (28/46) and 46.2％ (30/65) of strengthen follow-up group and control group respectively.The most frequent adverse effects were nausea 39.6％ (44/111),insomnia and abnormal dreams 17.1％ ( 19/111 ).Adverse effects were tolerable and withdraw symptoms were few.Preparation and medication time can be used as predictors of successful quitting.Conclusion The quit rate of varenicline therapy combining with strengthen intervention is high and strengthening psychological and behavioral intervention could increase the success rate more obviously,which is a good choice for cessation therapy in smoking cessation clinics.Better preparation and regular adequate treatment can improve quit rate.

A total of 133 smokers visiting our smoking cessation clinic from February 2009 to September 2010 were studied.The data were collected during initial assessments and over a follow-up period of 24 months.Long-term abstinence rate was observed.And logistic regression was employed to identify the independent predictors of successful quitting.There were 132 males and 1 female with a mean age of 47 years.They smoked an average of 26 cigarettes per day.The mean duration of smoking was 25 years.Among them,57 smokers (42.9％) were severely nicotine dependent and 76 smokers (57.1％) were followed up for 24 months.And 20 smokers (26.3％) maintained 24 month abstinence.The predictor of avoiding relapse was immediate family members being nonsmokers.

Objective To know the quality of iodized salt and the current situation of the salt coverage in Tibet,and to provide scientific basis for proposing proper prevention and control measures to Iodine dificiency disorders(IDD). Methods In 2008, according to the "Sampling Methods of the Main Products in the Salt Industry",one batch fifteen salt samples were collected in iodized salt processing factory in Tibet. Five townships were chosen in each county based on 5 different directions of east, south, west, north and center. If the monitoring county has less than five townships, then all of the townships were sampled. In each township, four villages were selected withrandom sampling and importance sampling. In each township, 15 households were selected for salt collection. Results A batch of 15 salt samples in a salt processing plant were tested, and all of them were qualified with salt iodine(34.6±1.58) mg/kg. A total of 21 107 edible salt samples were tested, and 11 203 of them were qualified iodized salt. These results meant that the provincial iodized salt coverage rate was 53.08%. Shannan iodized salt coverage rate was 94.31% (3395/3600) which was the highest in Tibet. Those of Nagqu, Changdu, Ngari were lower, they were 29.84% (897/3006), 24.94% (823/3300) and 17.08% (205/1200), respectively. Conclusions The quality of iodized salt in Tibet is up to the national standard, but the coverage rate of iodized salt is very low.We suggest that the strategy should be carried out according to the national overall program strategy and supplement iodized oil capsule for special groups.

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) plus oxiracetam in treating mild vascular dementia (VD) and seek its underlying mechanism. Methods: Ninety-six patients with mild VD were randomized into an observation group and a control group, with 47 cases in the observation group and 49 cases in the control group. The control group received oral oxiracetam capsules for treatment, and the observation group was given additional Tuina treatment. Before and after treatment, the mini-mental state examination (MMSE) was adopted to assess the patient's cognitive function; the activities of daily living (ADL) scale was used to evaluate their ability to conduct daily activities; changes in the serum inflammatory factors and oxidative stress indicators were also detected. Results: After treatment, the serum content of malondialdehyde (MDA) decreased in both groups (P<0.05) and was lower in the observation group than in the control group (P<0.05); the serum contents of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) increased in both groups (P<0.05) and were higher in the observation group than in the control group (P<0.05); the serum contents of interleukin (IL)-1, tumor necrosis factor (TNF)-α, IL-6, and IL-8 declined in both groups (P<0.05) and were lower in the observation group than in the control group (P<0.05). After the intervention, the levels of systolic velocity (Vs) and mean velocity (Vm) of the middle cerebral artery elevated, and the pulsatility index (PI) dropped in patients in the two groups, showing significant intra-group differences (P<0.05); the levels of Vs and Vm in the observation group were higher than those in the control group, and the PI was lower in the observation group than in the control group, showing significant between-group differences (P<0.05). The MMSE and ADL scores increased in both groups after the intervention (P<0.05) and were higher in the observation group than in the control group (P<0.05). Conclusion: In the treatment of mild VD, Tuina plus oxiracetam can improve the cerebral blood supply, ADL, and cognitive function; the mechanism may be associated with the reduction of oxidative stress damages and inflammatory reactions.

BACKGROUNDAmyloidosis is a collection of diseases in which different proteins are deposited. Amyloid deposits occur in systemic and organ-limited forms. In both systemic and localized forms of the disease, lung can be involved. The aim of this study was to explore the different respiratory manifestations of amyloidosis.

METHODSChest radiology, clinical presentations, bronchoscopic/laryngoscopic findings and lung function data of 59 patients with amyloidosis involving respiratory tract collected during January 1986 to March 2005, were analysed.

RESULTSOf the 16 cases with localized respiratory tract amyloidosis, 8 had the lesions in the trachea and the bronchi, 2 in the larynx and the trachea, 5 in the larynx and/or the pharynx, and 1 in the lung parenchyma. Of 43 systemic amyloidosis with respiratory tract involvement, 3 had the lesions in bronchi, 13 in lung parenchyma, 33 in pleura, 8 in mediastina, 1 in nose and 1 in pharynx. Chest X-rays were normal in most cases of tracheobronchial amyloidosis. CT, unlike chest X-rays, showed irregular luminal narrowing, airway wall thickening with calcifications and soft tissue shadows in airway lumen. Localized lung parenchymal amyloidosis presented as multiple nodules. Multiple nodular opacities, patch shadows and reticular opacities were the main radiological findings in systemic amyloidosis with lung parenchymal involvement. In pleural amyloidosis, pleural effusions and pleural thickening were detected. Mediastinal and/or hilar adenopathy were also a form of lung involvement in systemic amyloidosis. The major bronchoscopic findings of tracheobronchial amyloidosis were narrowing of airway lumen, while nodular, 'tumour like' or 'bubble like' masses, with missing or vague cartilaginous rings, were detected in about half of the patients.

CONCLUSIONSLocalized respiratory tract amyloidosis mostly affects the trachea and the bronchi. Chest X-rays are not sensitive to detect these lesions. Systemic amyloidosis often involves lung parenchyma and the pleura. Open lung biopsy or pleural biopsy should be performed for the diagnosis.

This study was aimed to investigate whether the extracts of Celastrus orbiculatus enhanced the invasion function of maspin tumor inhibitor gene through the construction of maspin overexpression human gastric carcinoma MGC803 cell line. Maspin was cloned into plasmid GV208-EGFP eukaryotic expression vector. And then, the recombinant plasmid GV208-maspin-EGFP was transfected into human gastric carcinoma MGC803 cells. After the maspin overexpression MGC803 cell were treated with Celastrus orbiculatus extracts in different concentrations (10, 20, 40 μg·mL-1), the invasion effects were detected by Transwell chamber assay. The results showed that after the successful construction of maspin overexpression cell line, the number of cells invading through Matrigel was obviously decreased in the Transwell chamber assay. It also showed drug concentration dependency. It was concluded that maspin gene can inhibit invasion of gastric carcinoma MGC803 cells. Simultaneously, the extracts of Celastrus orbiculatus can enhance the function of maspin gene.

Objective:To analysis clinical curative effect of laparoscopic radical prostatectomy bladder cancer and influence on serum levels of ferritin (SF),soluble interleukin-2 receptor (SIL-2 R) and rumor specific growth factor (TSGF).Methods:98 cases of bladder cancer who were treated in our hospital from August 2012 to February 2016 were selected and randomly divided into the control group 0=49) and the research group (n=49).The patients in the control group were treated with open radical radical cystectomy,while the patients in the research group were treated with laparoscopic radical cystectomy.Then the operation time,intraoperative blood loss,anal exhaust time,hospitalization,the lymph node cleaning,the serum levels of SF,SIL-2R,TSGF,white blood cells and cortisol,the complications and recurrence rate in the two groups were observed and compared.Results:The operation time of research group was longer than that of the control group,while the intraoperative blood loss,the hospitalization and the anal exhaust time were less than those of the control group,and the differences were statistically significant (P＜0.05).There was no statistically significant difference about the numbers of the lymph node and the recurrence rate between two groups (P＜0.05).After treatment,the serum levels of SF,SIL-2R and TSGF in the two groups decreased,while there was no statistically significant difference between the two groups (P＞0.05);After treatment,the white blood cell count and cortisol rise in the two groups increased,while the research group was lower than that of the control group (P＜0.05).Conclusion:LRC and ORC clinical efficacy similar,both of which can reduce the serum levels of SF,SIL-2R and TSGF of patients with laparoscopic radical prostatectomy bladder cancer.

OBJECTIVETo describe a form of interstitial lung disease pathologically characterized by small airway-centered interstitial fibrosis (ACIF).

METHODSWe analyzed the clinical, pulmonary functional, radiographic, and histologic characteristics of one ACIF case in Peking Union Medical College Hospital and reviewed 12 cases in literatures.

RESULTSClinically, patients presented with chronic cough and progressive dyspnea. Pulmonary function tests showed restrictive ventilatory pattern. Bronchoalveolar lavage showed a mild increase in lymphocytes in most cases. Chest radiography revealed diffuse reticulonodular infiltrates, with thickening of the bronchial walls and surrounding fibrosis. The key finding in histopathology was a distinctive pattern of ACIF centered on membranous and respiratory bronchioles.

CONCLUSIONSACIF is a disease that do not fit into any known category of interstitial lung disease. Whether it is a unique disease remains to be determined.

OBJECTIVETo assess the value of color Doppler ultrasonography, contrast-enhanced ultrasound and detection of serum CA-125 levels in the differential diagnosis of ovarian masses.

METHODSThe findings of color Doppler ultrasonography, contrast-enhanced ultrasound and the serum levels of CA-125 were comparatively analyzed in 65 patients with ovarian masses, and the diagnostic accuracy of the 3 methods was estimated.

RESULTSOf the 65 cases of ovarian masses, 21 of the 35 patients with benign ovarian masses had serum CA-125 levels below 35 U/ml , and 28 of the 30 patients with malignant masses showed CA-125 levels over 35 U/ml. Color Doppler ultrasonography identified 30 benign and 22 malignant cases, but failed to produce definite results in 13 cases (including 5 with benign and 8 with malignant masses). By contrast-enhanced ultrasound, benign masses were found in 34 cases and malignant masses in 29 cases, and misdiagnosis occurred in 2 cases (including 1 case of thecoma and 1 of ovarian borderline tumor). With serum CA-125 detection, color Doppler ultrasonography and contrast-enhanced ultrasound, the diagnostic sensitivity for ovarian masses was 66.7%, 73.3%, and 96.7%, and the specificity was 60.0%, 85.7%, and 97.1%, respectively.

CONCLUSIONSDetection of serum CA-125 level and ultrasound examinations help in the diagnosis and differential diagnosis of benign and malignant ovarian masses. Compared with serum CA-125 detection and color Doppler ultrasonography, contrast-enhanced ultrasound is more informative on perfusion patterns of the ovarian masses to result in higher accuracy in early and differential diagnosis of the ovarian masses.

OBJECTIVETo examine the correlation between the health-related quality of life measured by the St. George's Respiratory Questionnaire (SGRQ) and the commonly used physiological measures in lymphangioleiomyomatosis (LAM).

METHODSThis study retrospectively analyzed the SGRQ scores and other measures (the Borg scale of breathlessness at rest, 6-minute walking distance, blood oxygen levels, and pulmonary function) of patients diagnosed and confirmed with LAM. Altogether 38 patients between June 2007 and November 2009 were included.

RESULTSThe mean values of the SGRQ three components (symptoms, activity, and impacts) and total scores in the LAM patients were 46.95 +/- 28.90, 58.47 +/- 25.41, 47.89 +/- 29.66, and 51.11 +/- 26.35, respectively. The SGRQ total or component scores were correlated well with the Borg scale of breathlessness, 6-minute walking distance, partial pressure of oxygen in arterial blood, spirometry and diffusion capacity of lung. There were poor correlations between SGRQ score and residual volume or total lung capacity. In our preliminary observation, sirolimus improved the SGRQ total and three component scores and the Borg scale of breathlessness significantly after 101-200 days of treatment (n = 6).

CONCLUSIONSThe SGRQ score in LAM is correlated well with physiological measures (Borg scale of breathlessness, 6-minute walking distance, blood oxygen levels, and pulmonary function tests). The SGRQ could therefore be recommended in baseline and follow-up evaluation of patients with LAM. Treatment with sirolimus, an inhibitor of mammalian target of rapamycin, may improve the quality of life and patient's perception of breathlessness in LAM.
