1.Progress of indicators in the diagnosis of neonatal sepsis
International Journal of Pediatrics 2013;(2):148-151
Newborns,especially premature newborns,because of immature of immune function,have high incidence of sepsis.Today sepsis is still an important cause of neonatal death and poor prognosis.Unfortunately,clinical signs of sepsis are non-specific,so early diagnosis and treatment of the newborn infant with suspected sepsis are essential to prevent severe complications.Blood culture is the gold standard for diagnosis of sepsis,but the positive rote is low.Indicators in diagnosis of sepsis included acute phase reaction proteins,cytokines,cell surface antigen and bacterial DNA testing.This article compares and analyzes the indicators in diagnosis of neonatal sepsis.
2.DNA methylation in pancreatic carcinogenesis
Cancer Research and Clinic 2013;(2):133-135
Pancreatic cancer is one of the most malignant gastrointestinal tumors,characterized by a poor prognosis,absence of specific clinical symptoms and signs,prone to metastases and lack of response to conventional therapy.1 year survival rate of this disease increased to about 20 % by gemcitabine,but the morbidity and mortality rates are still higher and higher in the whole worldwide.DNA methylation is one of the mechanisms of epigenetics which is the study of heritable changes in gene expression that are not coded in the DNA sequence itself.It seems that DNA methylation indeed plays an important role in the development and progression of pancreatic cancer.
4.Apoptosis and mitochondrial membrane potential change of gastric smooth muscle cells in diabetic rats
Basic & Clinical Medicine 2006;0(10):-
Objective To investigate the pathogenesis of gastroparesis in diabetic rats.Methods SD rats were randomly divided into control group and diabetes group.Ten weeks later,gastroparesis model was established.The apoptosis rate and mitochondrial membrane potential of the gastric smooth muscle cells were detected by flow cytometry.Cytochrome C was detected by immunohistochemistry.Results Compared with rats in control group:(1)Typical symptoms of diabetes mellitus appeared;The rate of gastric residual pigment was significantly higher(P
5.The role of connexin 43 of heart tissues in experimental diabetic myocardial lesion
Chinese Journal of Diabetes 2006;14(4):288-289
The immunohistochemical staining showed the connexin 43 (Cx43) was strongly expressed (average gray value, AGV=230±5), distributed at junction area and intercalated disks of cardiocytes in normal rats,and much less expressed (AGV 193±4) (P<0.01) and distribution-disorganized in STZ-induced diabetic rats. This may be associated with the pathogenesis of diabetic myocardial lesions.
6.STUDIES OF ARTERIAL DISTRIBUTION OF THE M?LATISSIMUS DORSI, GRACILIS, TENSOR FASCIAE LATAE, GASTROCNEMIUS, SOLEUS
Acta Anatomica Sinica 1955;0(03):-
The arteries of the M. latissimus dorsi, gracilis, tensor fasciae latae, gastrocncmius and soleus were studied on 100 Chinese cadavers (40 fetus and babies, 60 adults) by dissection and arteriography. The origin, number, diameter and distribution of these arteries were observed, and were investigated quantitatively by means of MAGISCAN-Ⅰ Image Analyser.Based on the studies of the vascular anatomy of muscles. We classified the arterial distribution into three patterns: Type Ⅰ: The muscle of this group was supplied by one or two main arteries which coursed the entire muscle belly, as in: M. tensor fasciae latae, gastrocnemius, soleus. Type Ⅱ: The muscle of this group had a segmental supply of several arteries, which is distributed partially in muscle belly, as in: M. gracilis, soleus. Type Ⅲ: The musele of this group had a combination of both patterns of vascular arrangement, as in: M. latissimus dorsi, soleus.The muscles of Type Ⅰ and Type Ⅱ could often be divided into several regions which were based on the distribution of each branch of the artery.
7.Quality control study on Bidouyan mixture
Chinese Journal of Primary Medicine and Pharmacy 2013;20(17):2563-2565,后插1
Objective To explore the application of HPLC method in the determination of contents of ephedrine hydrochloride in Bidouyan mixture.Methods A HPLC method detected by one wavelength-210 nm for ephedrine hydrochloride had been developed.The chromatographic procedure for determination was carried out using DiamonsilTM C 18 (250mm x 4.6mm,5 μm) as an analytic column gradient eluted with a mixture consisting of acetonitrile and 0.05% H3PO4.Results The ranges of calibration curve of ephedrine hydrochloride was 0.011 ~ 0.277mg/ml.The established HPLC method was applied to determine 15 samples of Bidouyan mixture.The results showed that the ranges of ephedrine hydrochloride was 0.10 ~ 0.23mg/ml.Conclusion A simple,effective and feasible HPLC method to determine the contents of ephedrine hydrochloride was established for the quality control of Bidouyan mixture.
8.Research progress of proteomics techniques for the pathogenesis and early diagnosis in pancreatic cancer
International Journal of Surgery 2011;38(6):399-401
Therapeutic effect of pancreatic cancer depends on early detection and effective treatment.The early diagnosis of pancreatic cancer is so difficult that the discovery of pancreatic cancer is often in mid and late stages,so the treatment of meaning is not so satisfying.In recent years the rapid study of proteomics has brought great hope in the early discovery of pancreatic cancer to make it the post-genome era of functional genomics research in hot areas.Separating and identifying the serum、juice and tissue of patients with pancreatic cancer to find out the different proteins between normal and sick individuals can provide theoretical base and new ideas for the pathogenesis and early diagnosis of pancreatic cancer.
9.Analysis on program design and implementation of multi-sectoral and social participation projects
Chinese Journal of Disease Control & Prevention 2008;0(04):-
Relying on the R3 GF program,the present paper attempts to analyze the standards of multi-sectoral social participation projects design and implementation,to construct the key indicators and to explore the experience and bias,as well as to provide recommendations on how to improve performance and outcomes of small grant projects by multi-sectors.
