OBJECTIVETo investigate whether the major histocompatibility complex class I chain-related gene A gene (MICA) polymorphism and serum soluble MICA level were associated with the occurrence and development of colorectal cancer.

METHODSDNA samples from 117 colorectal cancer patients and 113 healthy individuals from Yangzhou in Jiangsu province were genotyped by using the polymerase chain reaction (PCR) and sequence-specific primer (SSP) method and PCR based sequencing. In addition, polymorphism at position 129 was also analyzed by PCR-SSP. Serum levels of soluble MICA were measured by a sandwich ELISA method.

RESULTSNeither the extracellular nor the transmembrane region polymorphisms of MICA gene were associated with the occurrence and the different stages of colorectal cancer. In contrast, the frequency of the methionine residue at position 129 was significantly decreased in the patient group. Soluble MICA levels in sera were increased in the late stages of colorectal cancer.

CONCLUSIONAlthough there was no genetic susceptibility attributed to MICA gene polymorphism with regard to development of colorectal cancer, serum levels of soluble MICA may be a diagnostic marker of advanced stages.

Results The positive expression rate of HPV16/18,p53,p21~(WAF1),MDM2 in ISCC was markedly higher than in CIN and NCE.We found the difference between HPV31/33 and lymph node transfer.Significant relation- ship was observed between p53 protein expression and histological grade and lymph node metastasis of the cancer.There was positive correlation between the expression of p21~(WAF1) protein and the depth of invasion(P

Objective To investigate the sanitation status of centralized air ventilation system in Putuo District of Shanghai, to analyze correlation between different indexes and to provide basis for improving the health status of public places and strengthening health supervision. Methods According to the requirements of WS 394-2012 The Sanitation Criterion of the Centralized Air Ventilation System in Public Places, 18 centralized air ventilation systems in public places in Putuo District of Shanghai were randomly selected for sampling, testing and evaluation during 2014-2018, and 9 indexes of air supply, inner surface of air duct and indoor air were analyzed for correlation. Results The overall qualified rate of centralized air ventilation system in 10 hotels, 4 restaurants and 4 supermarkets was 86.0%.The over standard rate of PM₁₀, bacteria and fungi in air supply was 3.4%, 31.8% and 33.0%, respectively, but β-hemolytic streptococcus was not detected.The dust amount and microbial index on the inner surface of the air duct were up to standard.Another two indexes of fresh air quantity and Legionella pneumophila were tested in the hotel.The qualified rate of fresh air quantity was 25.6%, the positive rate of Legionella pneumophila type 1(LP1) in cooling water was 30.0%, and no Legionella pneumophila was detected in condensate water.The correlation analysis of 9 indexes showed that there was a significant positive correlation between PM₁₀ in air supply and in indoor air; the amount of microbial pollution on the inner surface of air duct and in air supply; and the amount of microbial pollution in air supply and in indoor air. Conclusions In Putuo District, the general sanitary condition of the centralized air ventilation system in public places is not to be optimistic.The qualified rate of bacteria and fungi in the air supply and fresh air quantity is low, and Legionella pneumophila was detected.The indoor air quality can be improved by installing efficient air purification device and regular cleaning and disinfection.

Objective To investigate the attitudes of urban and rural community members toward total banning on smoking in public places and to explore the factors associated with these attitudes, in three counties/cities in China. Methods A cross-sectional study was conducted in three counties/cities in 2004, including Xin' an county of Henan province, Anyi county of Jiangxi province, and Mianzhu city of Sichuan province. A total of 5642 residents at age of 18-69 years old were interviewed face-to-face with a uniform questionnaire by locally-trained interviewers, through a random three-stage stratified sampling in each county. Factors were assumed to be associated with attitudes, using chi-square test in univariate analysis and non-conditional logistic regression model in multivariate analysis. Results The prevalence of current smoking among respondents was 44.3%. 80.7% (1379/1709) of the current smokers reported smoking often or sometimes in public places. Only 9.6% (479/4983) of the respondents reported that their indoor workplaces had totally banned on smoking. 43.5% of the respondents supported a total smoking ban strategy in pubic venues. The results of multivariate logistic regression model showed that eight factors were significantly associated with support for the total smoking ban in public places included region, residency, age, gender, education, smoking status, awareness about passive smoking hazards, and hearing of any message on tobacco control through media differences of rates regarding the factors as: residents in urban to rural areas (OR=1.29), elderly to youngsters (30-49 vs. 18-29, OR=1.46; 50-69 vs. 18-29, OR=1.71), female to male(OR=1.27), high-educated to less-educated ones, quitters to current smokers (OR=1.90), nonsmokers to current smokers (OR=2.01). Those who know messages on health hazards of passive smoking (OR=2.26), or heard of message on tobacco control through media (OR= 1.43). Conclusion Results from our study revealed that a thorough smoke-flee policy in public places should be developed and implemented in these three counties/cities.

OBJECTIVETo evaluate the performance of 18F-FDG three-head tomography with coincidence imaging and serum tumor marker assays in identifying lung lesions in 104 patients with abnormal findings on chest X-ray or computer tomography.

METHODSA prospective evaluation of 18F-FDG coincidence imaging and the measurement of 3 serum markers for lung cancer ( carcinoembryonic antigen, CYFRA21-1 and neuron specific enolase) were performed within one week in 104 inpatients with suspected lung malignancy. All images were analyzed visually. It was considered positive for malignancy if the 18F-FDG uptake was increased relative to that in the adjacent lung tissue, and was focal. The serum tumor marker test was considered positive for malignancy if the serum level of at least one marker was elevated.

RESULTS66 patients were proven to have lung cancer by pathology, and 38 patients had benign lung diseases. The sensitivity, specificity, accuracy of 18F-FDG coincidence imaging and serum tumor markers in assessing lung cancers were 80. 0% , 77. 2% , 77. 9% and 56. 0% , 60. 9%, 64. 4% , respectively. 18F-FDG coincidence images in assessing lung lesions showed significantly higher sensitivity, specificity and accuracy than serum tumor markers. Four patients with lung cancer had negative findings on 18F-FDG coincidence images but showed positive serum markers.

CONCLUSION18F-FDG coincidence imaging is a powerful tool for evaluating patients with lung lesions suggestive of malignancy. Although the determination of serum marker levels is less accurate than 18F-FDG coincidence imaging, the combination of a positive 18F-FDG coincidence result and positive tumor markers may be helpful in improving the diagnosis of lung cancers.

OBJECTIVETo evaluate the cardiovascular manifestations of Williams syndrome (WS) confirmed by fluorescence in situ hybridization (FISH).

METHODSBetween July 2004 and January 2007, FISH was used to confirm diagnosis in 71 suspected WS cases by detecting chromosome 7q microdeletion. Cardiovascular abnormalities were assessed by echocardiography and Doppler echocardiography.

RESULTSForty out of 71 patients were detected to have Elastin gene locus microdeletion, 25 patients (25/40, 62.5%) had at least one cardiac anomaly; among these patients, supravalvular aortic stenosis (SVAS) was diagnosed in 18 patients (18/25, 72%) and 6 of them had complex abnormalities. Patent ductus arteriosus was diagnosed in 3 patients (3/25, 12%, 1 was associated with other malformations), isolated pulmonary stenosis in 1 patient (1/25, 4%), isolated coarctation of aorta in 2 patients (2/25, 8%), and hypertension in 2 patients (2/25, 8%), mild aortic regurgitation in 2 patients, mild mitral regurgitation and moderate mitral regurgitation in 3 patients respectively.

CONCLUSIONA detailed cardiac evaluation should be performed in all patients with Williams syndrome due to the high frequency of cardiovascular abnormalities.

OBJECTIVETo investigate the correlation of serum sex hormones and parathyroid hormone (PTH) with the biochemical markers of bone turnover in aged men.

METHODSWe collected the laboratory data of 465 men aged 60- 93 (73. 1 +/- 8. 3) years old, who came for routine physical examinations in our hospital. We obtained the levels of serum follicle- stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), sex hormone binding globulin (SHBG), PTH, 25-hydroxy-vitamin D3 (25(OH) D3), and bone turnover markers C-terminal telopeptide of type I collagen (CTX), osteocalcin (OC) and amino-terminal propeptide of type I procollagen (PINP). We also determined free testosterone (FT) , bioactive testosterone (BT) , testosterone secretion index (TSI) and FT index (FTI), and analyzed the correlation of each index with the biochemical markers of bone turnover.

RESULTSThe concentrations of serum FSH, LH, and SHBG increased, while the levels of FT, BT, TSI, FTI, PTH, CTX, OC and PINP decreased with age, especially in those over 80 years old (P <0.05). PTH was positively correlated with CTX, OC and PINP (r =0. 227, 0. 269 and 0. 162, P <0. 01), even after the adjustment for age, while SHBG negatively correlated with OC (r = -0. 100, P <0.05). The bone turnover markers increased with the elevation of the PTH quartiles, with significant differences between the first and the fourth quartile (P <0. 01). Multiple stepwise regression analysis showed that age was correlated inversely with CTX, OC and PINP ( beta = -0. 126, -0. 141 and -0. 122, P <0.05) , PTH positively with the three markers (beta = 0. 196, 0.279 and 0.189; P <0. 001), and SHBG negatively with OC ( beta = -0. 100, P <0.05) .

CONCLUSIONAging is the fundamental cause of reduced bone turnover in aged men. The levels serum PTH and SHBG are significantly associated with the biochemical markers of bone turnover.

OBJECTIVETo observe the effect of Chuanhuang No.1 Recipe (CHR) on renal function and micro-inflammation in phase 3 chronic kidney disease (CKD) patients.

METHODSTotally 60 phase 3 CKD patients were randomly assigned to the treatment group (treated by CHR) and the control group (treated by Losartan Potassium), 30 in each group. All patients received basic treatment. Patients in the treatment group took CHR decoction, 400 mL each time, one dose per day, while those in the control group took Losartan Potassium, 50-100 mg per day. All medication lasted for 24 weeks. Changes of serum creatinine (SCr), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), serum uric acid (UA), 24 h urinary protein excretion (24 h U-pro), urinary microalbumin (U-Alb), high-sensitivity C-reactive protein (hs-CRP), serum tumor necrosis factor (TNF)-alpha, and serum IL-6 were detected and compared before and after treatment. Efficacy was also compared.

RESULTSCompared with before treatment, SCr and BUN significantly decreased in the treatment group (P<0.05, P<0.01); eGFR in- creased (P<0.05). Only UA obviously decreased in the control group (P<0.05), but with no obvious change in SCr, BUN, or eGFR. Compared with before treatment, 24 h U-pro decreased after treatment in the treatment group (P<0.05), but with less decreased level when compared with the control group. U- Alb was also significantly decreased in the control group (P<0.01). There was statistical difference in 24 h U-pro and U-Alb between the two groups after treatment (P<0.05). Compared with before treatment, hs-CRP obviously decreased after treatment in the two groups, but serum levels of TNF-alpha and IL-6 obviously decreased only in the treatment group (P<0.05). The total effective rate was obviously higher in the treatment group than in the control group (70.00% vs. 43.33%, P<0.01).

CONCLUSIONCHR could efficiently improve the renal function of phase 3 CKD patients and alleviate the micro-inflammation.
