Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(01):-
Objective To detect normal rat jejunum epithelial cells to learn about the distribution of peptide YY(PYY)receptor and measured two important parameters of PYY receptor so as to explore the target that PYY binds to and display its physiological function.Methods Receptor radioligand assay was conducted by using 125I-PYY to detect normal rat jejunum epithelial cells.We also measured receptor dissociation constant(Kd),the affinity or the ability that the receptor could bind ligand;maximum binding capacity(Bmax),the concentration of binding site;and Hill coefficient.Results There were PYY receptors in normal rat jejunum epithelial cells.Dissociation constant(Kd)of PYY receptor was(386.69?129.95)pmol/L.Maximum binding capacity(Bmax)was(303.21?116.85)fmol/mg protein.Hill coefficient was 1.PYY receptor had high affinity.Conclusion There are distributions of PYY receptors in normal rat jejunum epithelial cells.Kd means that PYY receptor has high affinity.Bmax means that the number of receptors is limited and decides the characters of saturability.We think that PYY directly inhibits secretion by binding to PYY receptor in jejunum epithelial cells when PYY inhibiting jejunum secretion.

6.Research on Ancient Literature of the Correlation Between Psoriasis and External Infection of Six Evil Factors
Chinese Journal of Information on Traditional Chinese Medicine 2015;(7):11-13
Psoriasis is a recrudescent chronic inflammatory dermatosis which is called“tinea”in ancient times. Its pathogenesis is not only associated with changes in the blood and body fluids, but also has close connection with external infection of six evil factors. This article sorted data of pathogenesis and treatment from the perspective of external infection of six evil factors, and discovered that pathogenesis of psoriasis includes external factors of four evils of wind, cold, damp and heat and internal factors of blood deficiency and blood dryness. Ancient treatment was based on dispelling wind, clearing away heat and moistening dryness. The pathogenesis can be summarized as follows:wind and poison attack skin and hinder blood production. The treatment can be “let in air for detoxification, enrich blood and moister dryness, cooling and activating blood”, blood and functional status of organs of patients should be observed, with a purpose to provide references and basis for modern clinical prevention and treatment of psoriasis.

Aim to explore the adverse drug reactions (ADR) characteristic and calculate the ADR incidence of Dengzhan Xixin injection (DZXX). A multicenter, large sample, and prospective cohort study was conducted from August 2012 to December 2014. A total of 31 724 patients using DZXX were observed. A total of 31 724 patients with 15 ADR cases among 31 724 patients, accounting for 0.06% , were reported. There were 8 male patients ADRs and 7 female patients with ADRs. ADRs included skin rashes, itching, headache, red face, abdominal pain, etc. 1 case with rhubarb radix scutellariae allergies. These ADRs happened from 5 min to within 0.5 h after DZXX were used to treat patients. ADR patients discontinued treatment, of which 2 patients used promethazine for recovery and improvement. There were 2 cases with different DZXX concentration, out of the normal range. DZXX injection could cause some ADRs. Users must not ignore these and be careful of its related side effects. This study was a cohort with large sample, which should produce strong evidence for clinical practice. However, there was still weak evidence to conclude that it was a safe Chinese medicine injection in clinical practice.

Objective:
To investigate the prevalence and influencing factors of dyslipidemia among adult residents in Hefei City, so as to provide the evidence for formulating the dyslipidemia control strategy.
Methods:
A total of 10 812 permanent residents at ages of 18 years were randomly sampled from 5 counties (districts) in Hefei City using a multi-stage stratified cluster random sampling method. Participants' demographic features, dietary behaviors and development of chronic diseases were collected using questionnaire surveys, and the height, body weight, waist circumference and blood lipids were measured. The prevalence of dyslipidemia was analyzed, and the factors affecting the development of dyslipidemia were identified using a multivariable logistic regression model.
Results:
Totally 10 812 valid questionnaires were recovered, with an effective recovery rate of 92.02%. The participants had a male to female ratio of 0.85∶1, a mean age of (51.89±12.56) years. The prevalence of dyslipidemia was 25.20%, and hypertriglyceridemia and low high-density lipoprotein cholesterol (HDL-C) were predominant types of dyslipidemia, with prevalence of 12.70% and 10.20%, respectively. Multivariable logistic regression analysis showed that urban areas (OR=1.340, 95%CI: 1.219-1.474), age of 40 years and older (40 to 59 years, OR=1.181, 95%CI: 1.047-1.333; 60 to 88 years, OR=1.321, 95%CI: 1.154-1.513), alcohol consumption (OR=1.205, 95%CI: 1.093-1.329), insufficient physical activity (OR=1.217, 95%CI: 1.111-1.332), static behavior duration of 3 h/d and longer (OR=1.126, 95%CI: 1.027-1.234), overweight (OR=1.162, 95%CI: 1.045-1.291), obesity (OR=1.310, 95%CI: 1.097-1.564), central pre-obesity (OR=1.236, 95%CI: 1.102-1.387), central obesity (OR=1.414, 95%CI: 1.247-1.603), hypertension (OR=1.279, 95%CI: 1.107-1.477), diabetes (OR=2.192, 95%CI: 1.820-2.640), medical insurance (OR=0.594, 95%CI: 0.395-0.893) and self-rated “very good/good” oral health (OR=0.731, 95%CI: 0.576-0.927) were factors affecting the development of dyslipidemia.
Conclusion
The risk of dyslipidemia is high among adult residents living in urban areas, middle-aged and elderly residents, residents with alcohol consumption, insufficient physical activity, overweight, obesity, central pre-obesity, central obesity, hypertension and diabetes.
