Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Changzhou City, Jiangsu Province, so as to provide insights into improving prevention and control strategies of dyslipidemia. Methods: Permanent residents aged 35 to 75 years were recruited based on the Early Screening and Comprehensive Intervention Project for High-risk Populations of Cardiovascular Disease in Changzhou City from 2016 to 2023. Demographic information, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were investigated through questionnaire surveys, physical examinations and laboratory tests, and the prevalence of dyslipidemia were analyzed. Factors affecting dyslipidemia were identified using a multivariable logistic regression model. Results: A total of 22 447 residents were surveyed, including 9 142 males (40.73%) and 13 305 females (59.27%), and had a median age of 57.00 (interquartile range, 18.00) years. There were 7 535 cases of dyslipidemia, with a prevalence rate of 33.57%. The prevalence rates of low HDL-C, high TG, high TC, and high LDL-C were 22.27%, 15.89%, 4.06% and 2.27%, respectively. Multivariable logistic regression analysis showed that the residents who were male (OR=1.780, 95%CI: 1.645-1.924), had more than 50 000 yuan of annual household income (OR=1.215, 95%CI: 1.142-1.293), had higher educational level (junior high school/senior high school/technical secondary school, OR=1.138, 95%CI: 1.047-1.237; junior college and above, OR=1.232, 95%CI: 1.095-1.386), smoked frequently (OR=1.504, 95%CI: 1.369-1.653), were overweight (OR=1.763, 95%CI: 1.650-1.885) or obese (OR=2.351, 95%CI: 2.149-2.572), had hypertension (OR=1.478, 95%CI: 1.384-1.579) and diabetes (OR=1.706, 95%CI: 1.586-1.835) had a higher risk of dyslipidemia; while the residents who consumed alcohol at 4 times per week and more (OR=0.619, 95%CI: 0.557-0.688) had a lower risk of dyslipidemia. Conclusions The main types of dyslipidemia are low HDL-C and high TG among residents aged 35 years and above in Changzhou City. The prevalence of dyslipidemia is mainly associated with gender, annual household income, educational level, smoking, alcohol consumption, BMI, hypertension and diabetes.

Objective: To evaluate the effect of nutritional support with low carbohydrate formula (Pulmocare, Abbott, America) in patients with pulmenary disease and respiratory failure. Methods: 60 patients were randomly divided into control group and study group. The study group was given Pulmocare and the control group was given Ensure (standard enteral nutrition,Abbott, America). The lipidemia, serum protein, PaCO 2 ,PaO 2 ,VO 2 ,VCO 2 and RQ were measured before and after therapy. Results: The patients' nutritional status of the two groups was improved significantly. The index of artery blood gas analysis was significantly improved( P

This study is to investigate protective effect of safflor yellow B (SYB) against vascular endothelial cells (VECs) injury induced by angiotensin-II (Ang-II). VECs were cultured and divided into six groups: control group, Ang-II group, Ang-II + SYB (1 micromolL(-1)) group, Ang-II + SYB (10 micromolL(-1)) group, Ang-II + SYB (100 micromolL(-1)) group and Ang- II + verapamil (10 micromolL(-1)) group. Except control group, all of VECs in other groups were treated with Ang- II at the final concentration of 0.1 micromolL(-1). Mitochondria membrane potential (MMP) and free calcium concentration ([Ca2+]i) were measured by laser scanning confocal microscopy, and mitochondria complex IV activity was detected by BCA method. The levels of reactive oxygen species (ROS) in VECs were analyzed by fluorescence detector and apoptosis of VECs was observed by flow cytometer. Caspase 3 was determined by Western blotting method. Comparing with control group, Ang-II was able to increase [Ca2+]i and ROS level, decrease MMP level, inhibit complex IV activity and enhance caspase 3 activity in VECs, as a result, enhance apoptosis of VECs. But SYB could significantly reduce the result induced by Ang- II relying on different dosages (P < 0.05 or P < 0.01). SYB was able to eliminate the effect of Ang-II on VECs via regulating [Ca2+]i, mitochondrial structure and function and inhibiting apoptosis.

Objective To evaluate the feasibility of methylene blue as a method in lymphatic mapping and the effect factors of SLNB identification rate. Methods The results of SLNB in 276 patients with clinical stage T-T2N0M0 breast eaneer were analyzed to evaluate the effect factors of identification rate and false-neg-ative rate of SLNB. Results The identification of SLN was carried out using methylene blne . When the mapping time of SLN and lymphatic were controlled in 20～30 minutes, the SLN could be visualized easily. SLN was successfully identified in 246 of 276 patients (89.1%) ,423 SLNs were retrieved(1～4). The SLN accurately predicted the status of the axilla in 226 of 246 patients (77.3%) yielding a FNR(false negative rate)of 8.1% (20/246) ,false positive rate of0, and an accuracy of 91.9% (226/241). For the identified rate of SLN, the clinical stage of T2N0M0 disease was higher than the clinical stage of T1N0M0 disease (P=0.046,P<0.05), Upper outer quadrant and lower outer quadrant were higher than other evidently (P<0.0010). SLNs were easily retrieved in those cases aged above 50 years than below 50 years (P<0.001).In the view of false-negative rate of SLNB, the FNR rate in patients of 50 years old was less than older ones (P=0.037, P<0.05). No significant correlation was found between the stage of TMN, the expression of ER and PR, histologic status and FNR. Conclusion When SLNB was performed using methylene blue, we found age, clinical stage of TMN, the location of tumor had relationship with the identified rate of SLN. Ag-ing and location of tumor may adversely affect FNR of SLNB.

Objective To analyze the effects of adenohypophysis function after treating with thyrotropin releasing hormone and its clinical significance in patients with brain trauma. Methods There were 22 cases with traumatic brain injuries from July 2010 to September 2012 in Chinese people's Liberation Army nine eight hospital,after injuried within 4 to 12 hours,then 1 1 cases who were given thyrotropin-releasing hormone(TRH)were selected as experimental group,while 1 1 cases who were given the same amount of isotonic saline were selected as control group,then the score of GCS, ICS,RLS85 and the improvement of adenohypophysis function were observed. Results After treatment,the score of glasgow coma scale (GCS ), innsbruck coma scale (ICS),and the reaction level scale (RLS85)between two groups were significantly increased in three days compared with before treatment,and within three days after injury situation,the improvements of ICS and RLS85 in experimental group were better than control group(P<0.05 ). Compared with control group,the levels of each gland pituitary hormone in experimental group were significantly increased(P<0.05 ),and on the third day,the growth hormone (GH)was reduced significantly,finally 50%of that in control group. Conclusion Patients with brain injury treated with thyrotropin releasing hormone,has no significant adverse reactions,with the characteristics of safe and effective.

Objective To investigate the relationship between neurogenic bowel dysfunction (NBD) and substance P in rats suffering from spinal cord injury (SCI). Methods 60 male Sprague-Dawley rats, weighted (220±40) g, were randomly divided into three groups: sham group (n=20), normal group (n=20) and model group (n=20) and then were subdivided into subgroups of 24 h, 1 week, 3 weeks, and 5 weeks respectively after SCI. SCI model was established at thoracic 10 segment of rat with NYU impactor device. The colon tissue of the rats was resected and stored. Substance P in serum and tissue was measured by ELISA. The tissue was examined by real-time RT-PCR and Western blotting to analyze the expression of substance P. Results The colon intestinal transmission function decreased and delineated at minimum value at 3 weeks in the model group. There was statistical significance with respect to the content of substance P in serum and tissue between the sham group and model group at 3 weeks. The expression of substance P in the sham group was (3.12±0.51) times of the model group (P<0.05). Conclusion Substance P may take part in NBD after SCI in rats.

Objective To explore the diagnosis, treatment and pathogenesis of solitary rectal ulcer syndrome (SRUS) in patients with spinal cord injury (SCI). Methods 260 patients with SCI accepted rectal diseases survey, anal examination and anus straight endoscopic. Those who had rectal ulcer also performed biopsy, and patients who had been diagnosed as SRUS were evaluated by the index of International bowel function basic SCI data set, then further accepted non-operative or surgical treatment, and regular reexamination with anal straight colonoscopy for clinical evaluation after discharge. Results and Conclusion Bowel dysfunction, constipation, and anal rectum prolapsed, improper uses of glycerine enema were important causes of SRUS after SCI. Non-operative therapy as well as strengthening defecate management could be an effective treatment for SRUS after SCI.

Objective To investigate the clinical significance of serum anti-Saccharomyces cerevisias antibody (ASCA),anti-outer membrane porin C (anti-OmpC),antibody to Pseudomonas fluorescens-associated sequence I2 (anti-I2 )and antibody to bacterial flagellin (anti-CBirl )in the diagnosis and treatment of inflammatory bowel disease (IBD).Methods From 2011 to 2013,87 patients with IBD were enrolled and divided into Crohn′s disease (CD)group (66 cases)and ulcerative colitis (UC)group (21 cases).A total of 62 age and gender matched healthy individuals were enrolled as the control group. Fasting blood samples (2 mL)of the subjects were collected.The expression of ASCA,anti-OmpC,anti-I2 and anti-Cbirl antibodies was detected with enzyme-linked immunosorbent assay (ELISA)kits.The diagnosis value of each antibody in IBD and the differential diagnostic value of in UC and CD were compared by receiver operating characteristic (ROC)curve.Results The area under the curve (AUC)of ASCA between IBD and the healthy control group,between CD group and UC group was 0.580 and 0.512, respectively;the accuracy in diagnosis was low.The AUC of anti-CBirl between IBD and the healthy control group was 0.617.There was no differential diagnosis significance of the other antibodies.The positive rate of ASCA in IBD group was 62.1 % (54/87),which was significantly higher than that in the control group (38.7%,24/62).The positive rates of anti-OmpC and anti-I2 in IBD group was significantly lower than those in the control group and the differences were statistically significant (both P <0.05).No difference was observed in positive rates of serum antibodies among the others groups (all P >0.05).The specificity,sensitivity,positive predictive value (PPV)and negative predictive value (NPV)of ASCA in differential diagnosis of CD and UC was 52.4%,66.7%,81 .48% and 33.33%,respectively.The specificity and sensitivity of anti-OmpC,anti-I2 and anti-CBirl in differential diagnosis of CD and UC was 81 .0% to 100.0% and 9.1 % to 37.9%,respectively.The specificity,sensitivity,PPV and NPV of double-positive ASCA and anti-I2 in the diagnosis of CD was 57.1 %,86.4%,82.6% and 50.0%, respectively.The positive rate of ASCA and anti-I2 in CD group was significantly higher than that in UC group (84.8%(56/66)vs 57.1 % (12/21 );χ2 =5 .633,P =0.018 ).Conclusions Positive ASCA has some significance in the diagnosis of patients with IBD in our country.The detection of anti-I2 can help to diagnose ASCA negative CD.Because of low sensitivity and positive rate,anti-OmpC and anti-CBirl have limited value in the diagnosis of IBD and the differential diagnosis of UC and CD in our country.
