Objective To evaluate the effect of twaist circumference(WC)on the blood pressure,lipid and glucose metabolism. Methods A baseline investigative data from community intervention target population for cardiovascular disease in Liuzhou was used. There were 7 660 residents (male was 3 894,female was 3 766),average aged 40.5?12.2 years. Their height,weight,WC,blood pressure,fasting plasma lipid and fasting plasma glucose(FPG) were detected. By WC length,they were divided as M

Objective To study the regulation of quorum sensing molecule tyrosol and farnesol on biofilm formation of Candida albicans. Methods Candida albicans biofilms of clinic isolates and standard strain SC5314 were built when quorum sensing molecule existed. And inverted microscope was used to observe the morphology of C. albicans cells. RT-PCR and MTT assay were carried out to investigate the effect of quorum sensing molecule on expression of the two genes (HTA1 and EFG1) and cytoactive. Results Tyrosol could not promote hyphae development and cytoactive of C. albicans biofilms. The expression of HTA1 of C. albicans in biofilms was up-regulated by tyrosol but EFG1 was not. The inhibitory effect of farnesol on hyphae development, cytoactive and gene expression were not changed by addition of tyrosol. Conclusion Tyrosol can make C. albicans biofilms active in early stage. But when tyrosol and farnesol were simultaneously added, the effect of tyrosol were masked by farnesol. And C. albicans cells were more sensitive to farnesol than to tyrosol.

OBJECTIVE To determine the distribution of pathogens of bacterial infection in respiratory intensive care unit (RICU) to provide reference for the prevention of hospital infection. METHODS To collect specimens of the patients received endotracheal intubation from Jan 2006 to Dec 2006 in our RICU,to identify pathogens and drug sensitivity test. RESULTS We isolated 105 pathogenic bacteria from 626 specimens of the 58 patients,the G-bacilli accounted for 64.76%,G+ cocci accounted for 20.95%,fungi accounted for 12.38%; Acinetobacter baumannii was one of the main G-bacilli accounted for 19.05%. Staphylococcus aureus of G+ cocci for 9.52%,and Candida albicans of fungi for 7.62%; from 105 pathogens,65 from the respiratory tract,15 from the for urinary tract,eight from a catheter tube,six from the digestive tract,five from the blood,four from the various drainage tubes and two from the incision secretions. CONCLUSIONS Hospital infection pathogens exist in the respiratory tract infection in hospitalized patients of respiratory ICU with risk factors of age,underlying diseases,time in the intensive care unit,ventilator time and the use of invasive procedures in a certain relationship.

Objective To investigate the clinical significance of PET-CT to diagnose breast cancer and the axiUary lymph nodes metastasis. Methods 40 patients with breast cancer performed PET-CT were enrolled in the research. Qualitation the primary tumor and accuracy of PET-CT were evaluated on pathological results and compared with axillary lymph nodes dissection. To analyzed the concordance of the size of primary tumor on pathological result with B-mode ultrasonic and PET-CT and the correlation with the SUV. Results The accuracy, sensitivity and specificity of PET-CT in identifying breast cancer were 95%, 94%, 100%. The accuracy, sensitivity and specificity of PET-CT based on the situation of the axillary lymph node dissection were 88.2% 89.2% 83.3%. A significant association was found between tumor weiweihong and PET-CT, furthermore it had not association with SUV. Conclusion The diagnosis of PET-CT in identifying breast cancer and the axillary lymph node metastasis basically conforms to pathology. It possesses high sensitivity and specificity especially in identifying the size of the primary lesion. It offers a beneficial method to determine the axillary lymph node dissection and reasonable therapeutic regimen.

Objective To investigate the influence of remote care management on the diet compliance and disease recurrence of patients with pancreatitis. Methods Seventy-four simple pancreatitis patients in our hospital from January 2013 to March 2014 were involved and numbered according to the administration order and divided into the observation group and the control group according to the random number table with 37 cases in each group. The two groups accepted conventional health education during hospitalization time. The control group was given intensive classes after discharge, while the observation group received remote care management. Twelve months later, the rate of disease recurrence and diet compliance of the two groups were observed and compared. Results After the management, the observation group was superior to the control group in diet compliance. The rate of disease recurrence was significantly lower in the observation group than that of the control group (all P<0.05). Conclusion The remote care management can effectively improve the diet compliance of pancreatic patients, lower the recurrence rate, and have positive effect on prognosis.

OBJECTIVE:To optimize water reflux extraction technology of Jiuwei yiwei mixture. METHODS:With the over-all score of the content of salvianoli acid B,a water-soluble component of the principal drug Salvia miltiorrhiza,the content of pae-oniflorin in Paeonia Radix Rubra and dry ointment yield rate as the observed index,and taking soaking time,extraction time, amount of water added,and extraction times as the factors,L9(34)orthogonal test was designed to optimize the extraction technolo-gy of Jiuwei yiwei mixture. And the verification test was conducted. RESULTS:The optimal technology was to add water with an amount 8 times as much as that of the drugs to soak them for 1 h and to conduct extraction twice,1 h for each. The overall scores of 3 batches of samples in the verification test were respectively 98.793,99.078 and 99.220(RSD<2%,n=3). CONCLUSIONS:The optimal technology for Jiuwei yiwei mixture is stable and feasible.

Objective To explore the changes and significance of serum tumor necrosis factor-?(TNF-?),interleukin-1?(IL-1?),IL-6 and IL-10 in rats with acute necrotizing pancreatitis(ANP).Methods Sixty-four Wistar rats were randomly divided into 2 groups: sham operation group(SO group n=32) and ANP group(n=32).The ANP model was established by using retrograde injection of Sodium Taurocholate into cholangiopancreatic duct.The changes of serum endotoxin(ET),TNF-?,IL-1?,IL-6 and IL-10 in different groups and different time points were observed.Results The levels of serum ET,TNF-?,IL-1?,IL-6 and IL-10(except IL10 of ANP group in 16h) in rats of ANP group were significantly higher than those of SO group(P

Objective To explore the spread patterns of retropharyngeal lymph node (RLN) metastasis of nasopharyngeal carcinoma. Methods From July 2003 to March 2005, three hundred and three patients with nasopharyngeal carcinoma in initial treatment were enrolled in this study. All patients underwent magnetic resonance imaging (MRI) before treatment, meanwhile measured the minimal and maximal axial diameters, the longitudinal diameter and the central and craniocaudad locations of each positive RLN. Results A total number of 264 positive RLN were found in 177 patients. The minimal and maximal axial diameters and longitudinal diameter of positive RLN were 9.9, 12.9 and 22.4 mm, respectively. Ipsilateral metastatic RLN were noted as follows: two nodes in 21 patients, three nodes in 3 patients and four nodes in 1 patient. According to the longitudinal central location of 263 positive lateral RLN, the numbers of nodes at occipital bone, C1, C1/C2, C2, C2/C3 and C3 were 27, 166, 40, 23, 5 and 2, respectively; the mean minimal axial diameters of nodes were 6.8, 9.9, 12.5, 10.4, 9.3 and 8.0 mm, respectively. Conclusion Multiple metastatic ipsilateral RLN are not common in NPC. The rate of RLN metastasis shows the trend of decreasing from vertebral C1 to C3.The maximal diameters of RLN are in the C1/C2 intervertebral space, and reveal a decreasing frequency along the craniocaudal directions of occipital and vertebral C1.
