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 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.
4.A randomized, controlled, multi-centre clinical study on the efficacy of flupenthixol melitracen in the treatment of patients with functional dyspepsia accompanied by depression
Chinese Journal of Digestion 2013;33(7):446-450
Objective To explore the efficacy of flupenthixol melitracen in the treatment of functional dyspepsia (FD) and its effects on receptivity expansion and visceral sensitivity.Methods A randomized,controlled,multi-centre study was carried out.The FD patients with depression were divided into anti-depression group and control group.The patients of both groups received omeprazole and mosapride treatment for eight weeks.The patients of anti-depression group added flupenthixol melitracen and psychotherapy.Before the treatment,by the end of the second,fourth,sixth and eighth week of the treatment,the scores of upper gastrointestinal symptoms and adverse effects of the patients of the two groups were recorded,the psychological status was evaluated by Hamilton depression scale and the gastric receptivity expansion and visceral sensitivity were assessed by water loading test (WLT).The data were analyzed by t test and chi-square test.Results Among two hundred and fifty enrolled FD patients with depression,245 patients (129 in anti-depression group,116 in control group) were enrolled in intention-to treat analysis.Before the treatment and by the end of the eighth week of the treatment,the scores of upper gastrointestinal symptoms of anti depression group were 12.23±4.45 and 2.31±2.13 (t=22.837,P=0.008),the control group were 12.29± 4.62 and 8.58±3.76 (t=6.708,P=0.184).By the end of the eighth week of treatment,the difference between the two groups was statistically significant (t =16.261,P<0.05).By the end of the fourth and eighth week of treatment,the total effective rates of the improvement of upper gastrointestinal symptoms of anti-depression group were 76.0% (98/129) and 83.7% (108/129),control group were 14.7 % (17/116) and 25.9 % (30/116),the differences between the two groups were statistically significant (x2 =92.191 and 83.117,both P<0.05).By the end of the eighth week of treatment,the total effective rate of the improvement of depression of anti depression group was 71.3% (92/129),which was higher than that of control group (23.3%,27/116),the difference between two groups was statistically significant (x2 54.434,P<0.01).Before the treatment,the maximum WLT volume of anti depression group was (850±130) mL,by the end of the eighth week of treatment was (1400±210) mL (t=25.292,P<0.01).Before the treatment and by the end of the eighth week of treatment,the maximum WLT volumes of control group were (800± 120) mL and (960±140) mL (t=9.345,P<0.01).All the adverse effects of anti depression therapy were mild.Conclusion The treatment of flupenthixol melitracen can improve the efficacy in patients with FD,relieve the depression status,improve gastric receptivity expansion and visceral sensitivity with a good safety and tolerability.
5.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.

Chinese Journal of Biochemical Pharmaceutics 2015;35(10):85-87
Objective To observe effect of Rho kinase inhibitor combined with hyperbaric oxygen on the recovery of neurological function after spinal cord injury in patients with thoracolumbar fractures.Methods A total of 80 cases of thoracolumbar fractures combined with spinal cord injury patients as the research object, the packet by the standards of admission of single and double serial number, odd numbers were divided into control group, even number were divided into treatment group (40 cases in each group); two groups underwent surgical treatment, control group was given single usage fasudil treatment, treatment group was given hyperbaric oxygen therapy for auxiliary therapy on the basis of control group, Continuous treatment for two months.Compared neurological function scoring, grading, blood superoxide dismutase (SOD) , epithelial growth factor (EGF) , lipid peroxide (LPO) and adverse reactions pre-and post-treatment between two groups of patients.Results After treatment,total effective rate of treatment group (92.50%), ASIA sensory, movement scores were significantly higher than control group (75.00%)(P<0.05);Content of SOD and EGF of treatment group were significantly higher than control group(P<0.05);the adverse reaction rate (12.50%) was significantly lower than that of control group (32.50%)(P<0.05).Conclusion Rho kinase inhibitor combined with hyperbaric oxygen can significantly improve the degree of injury, neurological function and blood SOD, EGF, LPO content in patients with lumbar vertebral fractures combined with spinal cord injury, and the adverse reactions are few, has definite clinical effect.
8.Roles of connexin in breast cancer
Journal of International Oncology 2014;41(4):273-276
The previous studies identify connexin as a tumor suppressor gene,which inhibits the occurrence and development of breast cancer.However,some researches of resent years demonstrate that the expression level of connexin in a large part of metastatic breast cancer is elevated and connexin may promote breast cancer metastasis.Therefore,connexin may play different roles by different mechanisms in the occurrence,development,invasion and metastasis of breast cancer.Rational use of connexin in breast cancer treatment can be beneficial to breast cancer patients.
