1.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.
2.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.
3.The causes and countermeasures of non-response to anti-vascular endothelial growth factor therapy
Chinese Journal of Ocular Fundus Diseases 2016;32(4):444-448
The therapeutic response of anti-vascular endothelial growth factor (VEGF) differs among individuals.According to the changes of central retinal thickness,intraretinal fluid,subretinal fluid,best corrected visual acuity and other morphological or functional manifestations after treatment,the performance of the treated eyes can be classified as optimal response,poor response and non-response.A variety of factors could account for poor or non-response to anti-VEGF,such as genomic polymorphism and specific genomic risk alleles,lesion characteristics,vitreous and macular structural abnormalities,resistance to anti-VEGF drug,and the role of pericytes and others.The common counter measures include increasing the dosage,shortening the injection interval and replacing with another alternative drug,inhibition of pericytes,relieving vitreomacular anatomical abnormalities.It is still worthy of further exploration that how to assess individual reasons for non-response,so that we can give proper treatment to reduce the excessive use of anti-VEGF drugs and improve the clinical management of ocular neovascularization diseases.

0.05).The effective rates of the two treatment schemes were 90%,87%.The cost effectiveness ratio were 108.61 and 76.35.Conclusion Homemade octreotide is better in the treatment of severe acute pancreatitis.
7.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.
8.Clinical Study on Actovegin in the Treatment of 38 Patients with Diabetic Peripheral Neurapathy(DPN)
Journal of Medical Research 2006;0(06):-
Objective To observe the effect of actovegin on diabetic peripheral neurapathy (DPN).Methods 76 patients with DPN were divided into treatment and control groups at random.Two groups were treated routinely with general treatment on DM and the treatment group was added routine dose of actovegin while the control group were treated with Methycobal.After 8 weeks,the effective rate,MCV and SCV were determined.Results The general effective rate and MCV and SCV in treatment group were higher markedly than control group.Conclusion Actovegin can improve DPN effectively.

To observe the effects of Danshen on the growth of hepatocellular carcinoma in the SD rats, a model of malignant obstructive jaundice was established by inoculation of transplanted tumor into the hepatic portal with the walker-256 hepatocarcine line, which resulted in the obstruction by the infiltration and metastasis of hepatocellular carcinoma. SD rats were divided into 4 groups: the rats were treated by 0.9 % NS (n=24, control group), inosine+vitamin C (n=40, InV group), Danshen (n=40, DS group) and 5-FU (n=40, 5-FU group), respectively. The liver function, morphological changes and the expressions of PCNA, VEGF and ICAM-1 in carcinoma foci, peri-carcinoma tissues, adjacent lobe (left-internal lobe) and lung tissues were observed after the treatment with the 4 agents. Our results showed that the protective effect of Danshen on liver function was significantly better than that of NS and 5-FU (P<0.01). No significant difference in protective effect was observed between DS group and InV group (P>0.05). Danshen also provided protective effect on the morphological damage of liver caused by obstructive jaundice. The rates of carcinoma-inhibition and metastasis inhibition were significantly higher than those of NS and inosine+vitamin C (P<0.01). No significant difference in this regard existed between DS group and 5-FU group (P>0.05). The expressions of PCNA,VEGF and ICAM-1 PCNA, VEGF and ICAM-1 in carcinoma foci, peri-carcinoma tissues, adjacent lobe (left-internal lobe) and lung tissues were lower than those in control group and InV group, with the differences being significant (P<0.01). No significant differences were found between DS group and 5-FU group in the expression levels of PCNA and VEGF (P>0.05) but ICAM-1 (P<0.05). It is concluded that Danshen injection not only has protective effects on liver injury caused by obstructive jaundice, but can inhibit the proliferation and growth of hepatocarcinoma, interfere with the vascularization of tumors, prevent recurrence and metastasis of hepatocarcineoma.
10.Research advances in molecular prediction of recurrence and metastasis of primary liver cancer after liver transplan-tation
Journal of Clinical Hepatology 2014;30(12):1361-1365
Liver transplantation is an essential treatment of primary liver cancer,but the postoperative high risk of recurrence and metastasis has seriously affected the effect of liver transplantation.With the development of molecular biology,researchers have found numerous molec-ular markers potentially related to the recurrence and metastasis of liver cancer after liver transplantation.These markers,including genes, proteins,tumor markers,and serum viruses,are summarized,and their predictive values for tumor recurrence and metastasis after liver transplantation are analyzed.A growing number of molecular markers have been found,but which is not enough for clinical guidance.There-fore,more studies are needed to identify appropriate molecular markers of tumor recurrence and metastasis after liver transplantation.
