Objective:To explore the clinical value of X-ray and CT in detecting unusual mediastinal mass.Methods:The chest plain films and CT scans were performed in all 9 cases .Results:Nine cases proved by operation and pathology included liposarcoma(two cases),multiple neurinoma(two cases),neuroendovrine cartinoma(two cases),endodermal sinus tumor(two cases)and thymas cacinoid (one case).Conclusion:X-ray and CT can localze the mediastinal mass,CT has more significance in detecting the internal morphology of mediastinal mass and its relationship with the surrounding tissues.But there is still a limitation for X-ray and CT in detecting the quality of some mediastinal carcinomas.

Objective:To investigate the regulation of acupuncture on γ-interferon (INF-γ) and tumor necrosis factor (TNF) of lung cancer-operative cases. Methods: to determine the INF-γ and TNF contents in the blood serum of lung cancer patients by double antibody sandwich immuno-enzymatic method (ELISA); to measure the INF-γ and TNF contents of 30 lung cancer patients in the acupuncture anesthesia group and 30 lung cancer patients in general anesthesia group before the operation and at the 8th days, the 12th day after the operation respectively and make comparison between the two groups. Results:The pre-operation INF-γ contents of the two groups showed no significant difference (P＞0.05); the post-operation INF-γ contents of the two groups showed significant difference at 8th day and 12th day after the operation (P＜0.05); the acupuncture anesthesia group was superior to the general anesthesia group; the self-comparison of the anesthesia group showed significant difference at the 12th day and 8th day after the operation (P＜0.05); the pre-operation TNF contents of the two groups showed no significant difference (P＞0.05) and the post-operation TNF contents of the two groups showed significant difference at the 8th day and 12th day after the operation (P＜0.05). Conclusion:Acupuncture can increase the serum INF-γ and TNF contents of lung cancer patients and therefore regulate the immunity of the patients.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.

METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.

RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.

CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.

Objective To comparing the diagnostic and therapeutic strategies for patients with benign prostatic hyperplasia(BPH) between doctors in general hospitals and community hospitals,and to provide scientific clues for the standardization in medical practice.Methods General and community hospitals in urban China were selected via the stratified sampling.127,325 outpatients in these hospitals from December 2011 to December 2012 were randomly recruited.Results The average age of patients was(67.82±8.62) years.There were significant differences in I-PSS,prostate volume,urinary flow rate(UFR) and result of digital rectal examination(DRE) between patients in general and community hospitals.The rates of diagnostic applications were different between doctors in the two kinds of hospitals except I-PSS.Compared with community hospitals,DRE was more frequently applied while ultrasonic inspection and UFR test were less used in general hospitals in North China.A totally opposite situation was observed in East China as compared with the north.The application rates of DRE and UFR test were lower and ultrasonic inspection rate was higher in community hospitals than in general hospitals in South China.Pharmacotherapy was the most common treatment for BPH patients in both types of hospitals(97.53 ％).The rates of drug combinations were statistically different but both were close to 75％ in the two types of hospitals.In community hospitals,the percentage of patients receiving watchful waiting with severe symptoms and signs were lower than that of patients receiving watchful waiting with moderate symptoms and signs,but the percentage of patients receiving operation was not significantly increased.On the contrary,the percentage of patients receiving operation with severe symptoms and signs was higher than that of patients receiving operation with moderate symptoms and signs in general hospitals,but the percentage of patients receiving watchful waiting was not decreased.Conclusions Applications of diagnostic methods are significantly different between doctors in general hospitals and community hospitals and vary among regions.Therapeutic strategies are correlated with the severity of obstructive symptoms or signs.The medication strategy is similar between the two types of doctors.

Objective To describe the distribution of body mass index (BMI) and evaluate the prevalence of overweight and obesity among first to sixth graders in 8 Chinese provinces.Methods Data came from the baseline survey of the Chinese Center for Disease Control and Prevention (CDC) funded project Study on Intervention Models for Main Chronic Diseases among children in China.A stratified random cluster sampling strategy was used to select study participants in 8 provinces,including Inner Mongolia,Jiangsu,Anhui,Shandong,Hunan,Guangxi,Gansu provinces,and Chongqing,with diverse geographical and economic level distributions in China.Counties in each province were stratified into three strata according to economic level,and one county was selected systematically from each stratum.In each county,one urban and one rural elementary school were randomly selected ; and in each school,2-3 classes were randomly selected from each of 1-6 grades.All students in these selected classes were invited for participation.Physical examination was performed by trained local CDC staff using standardized instruments to measure height and weight.Overweight and obesity were diagnosed based on the BMI classification standards for Chinese children and adolescents by Working Group for Obesity in China (WGOC).Results A total of 26558(14225 boy,12333 girl) students aged 6-12 years eventually participated in 8 provinces.The average age was 9.3 ±1.8 years old.Mean BMI among boys (17.0 kg/m2) was higher than that among girls (16.4 kg/m2,t =19.60,P＜0.01).There were statistically significant differences in mean BMI of each age group of boys and 6-11 age groups of girls between urban and rural regions and among those with three economic levels (P＜0.05).The 85th and 95th percentiles of BMI among boys aged 7-11 years in urban region were higher than BMI reference in the standards from WGOC.Lower percentiles were observed among girls aged 7-12 years in rural region.The prevalence of overweight and obesity were 9.3％ and 6.5％ among schoolchildren aged 7-12 years.The prevalence of overweight among boys (10.9％) was higher than that among girls(7.6％,x2 =88.89,P＜0.01) ; while prevalence of obesity were 8.0％ among boys and4.7％ among girls,respectively (x2 =107.17,P＜0.01).The prevalence of overweight was 11.3％ in urban and 7.4％ in rural children(x2 =131.94,P＜0.01).The prevalence of obesity was 8.7％ in urban and 4.3％ in rural children(x2 =188.99,P＜0.01).The prevalences of overweight were 10.3％,8.6％ and 9.0％ in individuals with high,medium,and low economic levels,respectively(x2 =10.76,P＜0.01) ; while the prevalences of obesity were 8.2％,5.6％,and 5.4％,respectively (x2 =51.71,P ＜ 0.01).Conclusions The overall prevalence of overweight and obesity in Chinese school children was high.The prevalence in urban region with high economic level was significantly higher than that in rural region with middle and low economic level.The nutritional and behavioral intervention programs are needed to control the rising trend of obesity in children.

OBJECTIVETo investigate the effects of rhodiola on expression of vascular endothelial cell growth factor (VEGF) and angiogenesis in aortic atherosclerotic plaque of rabbits.

METHODSThirty male New Zealand rabbits were randomly divided into 3 groups equally, i. e. the control group (A) fed with common diet and treated with distilled water, the high fat diet group (B) and the rhodiola group (C) fed with diet containing 1.5% cholesterol and treated respectively with distilled water and rhodiola (1 mL/kg per day), all the treatments were administered via gastrogavage once a day for 9 successive weeks. Level of blood lipids in various groups was determined and compared at the end of the experiment. Meanwhile, the tissue sample of aorta was taken for observation through HE and Sudan red staining, for detecting the CD34 positive response intensity by immunohistochemical staining and the VEGF expression by Real-time fluorescent quantitative PCR and Western blot.

RESULTSDetermination of blood lipids showed that in Group C, TC was 42.01 +/- 1.99 mmol/L, TG 4.83 +/- 0.75 mmol/L and LDL-C 38.40 +/- 0.74 mmol/L, all lower than those in Group B (70.74 +/- 2.66 mmol/L, 8.75 +/- 0.78 mmol/L and 51.05 +/- 0.34 mmol/L, respectively), showing statistical difference between groups (P < 0.05). The intima/media tunica thickness ratio and the CD34 positive area of plaque in Group C were all lower than those in Group B (0.35 +/- 0.03 vs 0.43 +/- 0.03 and 29.12 +/- 2.56% vs 39.28 +/- 3.48%, P <0.05). Besides, the VEGF expression in atherosclerotic plaque was also lower in Group C than that in Group B.

CONCLUSIONRhodiola has the effects of inhibiting atherosclerosis formation, decreasing the VEGF expression and suppressing the angiogenesis in the plaque.

OBJECTIVETo investigate the effects of Shexiang Baoxin Pill (SBP) in intervening atherosclerosis and myocardial infarction (AS-MI) in experimental animals, and inspect its influences on angiogenesis.

METHODSTwenty male New-Zealand rabbits were made into AS-MI model, and randomly divided into 2 groups equally. Group A was fed with high-fat diet for control; Group B was fed with high-fat diet but intervened with SBP. The cardiac function and the positive area of plaque were determined. The CD34 positive response intensity at infarcted marginal zone and aorta vessel wall, and the capillary density of myocardium were measured by immunohistochemical staining. In addition, the protein expressions of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR-2) were detected by Western blot.

RESULTSCompared to Group A, the cardiac function was obviously improved (P<0.05) and the plaque positive area (%) was significantly decreased in Group B (45.82 +/- 3.68 vs 82.56 +/- 4.97, P<0.01). The CD34 positive response intensity and the capillary density as well as VEGF and VEGFR-2 expressions in infarcted marginal zone in Group A were higher than those in Group B (P<0.01); but these parameters at aorta vessel walls were lower in Group A than in Group B (P<0.01).

CONCLUSIONSBP could advance the angiogenesis in the marginal zone of infarction, improve heart function, and embarrass angiogenesis in atherosclerotic plaque.
