1.Diagnosis and treatment of chronic pancreatitis with mass in the head of the pancreas
International Journal of Surgery 2010;37(9):612-615,封3
Chronic pancreatitis (CP) with mass and pancreatic cancer are difficult to identify from the Clinical performance. Imaging methods in the diagnosis of the CP with mass play an important role, which is very helpful for the indications for surgery of the hands, of resectable pancreatic head tumor, and surgical options, as well as estimates of the difficulty of the surgery. At present, we have taken the CP with mass as a precancerous lesion of pancreatic cancer. Surgical strategy in CP with mass has been directed at the pancreatic head with a variety of tactics including pancreatoduodenectomy ( Whipple procedure with or without pylorus preservation) and partial resection of the pancreatic duct drainage( Frey operation, Beger operation ). Once the diagnosis of the CP with mass was confirmed surgical treatment should be performed by pancreatoduodenectomy, which by not only the pancreatic head mass was resected, the bile ducts and pancreatic ducts and obstruction of the duodenum were lifted, but also the potential causes of pancreatic cancer were ruled out. Pancreatoduodenectomy has great risk for the big mass of pancreatic head, but the partial head resection can be accomplished with relative safety.

4.The expression and effect of interleukin-13 in renal tissues in patients with primary glomerulonephritis
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(02):-
Objective To study the expression of interleukin-13(IL-13) in renal tissues of several common pathologic types of primary glomerulonephritis(PGN).Methods Immunohistochemistry was used to examine the expression of IL-13 in renal tissues of 81 patients with PGN and 10 normal control cases.The correlation analysis was performed with biochemical and pathological indicators.Results Extensive expression of IL-13 was found in renal tissues of patients with PGN.The expression of IL-13 in renal tissues was positively correlated with the concentration of blood urea nitrogen,serum creatinine,the quantitation of urine protein and the crescent formation in glomerular(r=0.325,0.275,0.291,0.231,respectively).It was negatively correlated with glomerular filtration rate and serum albumin(r=-0.448,-0.296,respectively).Conclusion IL-13 participates in the process of inflammation reaction and crescent formation in the renal tissues in patients with PGN,and is correlated with the progression of renal function and the level of urea protein.
5.Multidrug resistance-associated protein 1( MRP1/ABCC1 ) polymorphism: from discovery to clinical application
Journal of Central South University(Medical Sciences) 2011;36(10):927-938
Multidrug resistance-associated protein 1 (MRP1/ABCC1) is the first identified member of ABCC subfamily which belongs to ATP-binding cassette (ABC) transporter superfamily.It is ubiquitously expressed in almost all human tissues and transports a wide spectrum of substrates including drugs,heavy metal anions,toxicants,and conjugates of glutathione,glucuronide and sulfate.With the advance of sequence technology,many MRP1/ABCC1 polymorphisms have been identified.Accumulating evidences show that some polymorphisms are significantly associated with drug resistance and disease susceptibility.In vitro reconstitution studies have also unveiled the mechanism for some polymorphisms.In this review,we present recent advances in understanding the role and mechanism of MRP1/ABCC1 polymorphisms in drug resistance,toxicity,disease susceptibility and severity,prognosis prediction,and methods to select and predict functional polymorphisms.
6.Endoscopic endonasal dacryocystorhinostomy assisted by image guidance system to chronic dacryocystistis.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(17):1343-1346
OBJECTIVE:
To estimate the value of nasal endoscopic dacryocystorhinostomy combined image guidance system in treating chronic dacryocystistis.
METHOD:
Thirteen cases (14 eyes) performed surgeries with nasal endoscopic dacryocystorhinostomy combined image guidance system from January 2010 to August 2013 were retrospectively analyzed. Their clinical data were analyzed and the effect of the surgery was evaluated.
RESULT:
All patients were followed-up for more than half a year. Of all patients,12 eyes were cured, 2 eyes were improved and 0 eyes were noneffective. The total treatment effectiveness was 100%. There was no complication for all cases.
CONCLUSION
Nasal endoscopic dacryocystorhinostomy combined image guidance system is an effective and reliable treatment method for chronic dacryocystistis, especially for intraoperative location of lacrimal sac and control of operating process.

Journal of International Oncology 2017;44(2):151-154
High resolution magnetic resonance imaging (HRMRI) has become an indispensable tool for multidisciplinary teams addressing locally advanced rectal cancer.Preoperative HRMRI is accurate in predicting tumor stage and poor prognostic features,such as circumferential resection margin and extramural venous invasion,et al.HRMRI is a precise diagnostic tool to select who may benefit from neo-adjuvant therapy and to avoid over treatment in those patients who can proceed directly to surgery,thus achieving better prognosis and quality of life for patients with locally advanced rectal cancer.
10.Inhibitory effect and its molecular mechanisms of MicroRNA-34a on human na-sopharyngeal carcinoma CNE-2 cell line subcutaneous xenograft tumor in nude mice
Chinese Journal of Immunology 2015;(7):912-916
Objective:To investigate the inhibitory effect and its possible molecular mechanisms of MicroRNA-34a(miR-34a) on the human nasopharyngeal carcinoma CNE-2 cell line subcutaneous xenograft tumor in nude mice.Methods: The human nasopharyngeal carcinoma CNE-2 cell line was cultured in vitro.miR-34a and Scrambled miRNA recombinant plasmids were successfully established and stably transfected into CNE-2 cells.Fifteen six-week-old male nude mice were divided randomly into three groups:miR-34a group(5 mice) ,Scrambled miRNA group(5 mice) ,Blank control group(5 mice).Different CNE-2 cells were subcuta-neously injected on the back near right lower limb.Tumor volumes were examined every 7 days.Mice were executed on the 35 days,and the eventual average tumor volumes and weights were examined.Total RNA and protein were isolated from tumors,and the expression of miR-34a,CDK6,and Bcl-2 mRNA and protein were determined by qRT-PCR and western blot,respectively.Results: The relative expressions of miR-34a was significantly up-regulated in miR-34a transfected group compared to Scrambled miRNA transfected group (P<0.05).Eight subcutaneous xenograft tumor models were successfully established.The nude mice of miR-34a transfected group appeared a smaller tumor volume compared to the other two groups at the beginning of 21th day( P<0.05).The eventual average tumor volumes in miR-34a group,Scrambled miRNA group and blank control group were(351.37±98.19)mm3,(798.75±91.04)mm3 and
(849.62±101.32) mm3 ,respectively,and the eventual average tumor weights in miR-34a group,Scrambled miRNA group and blank control group were(0.81±0.13)g,(1.47±0.21)g and(1.58±0.37)g,respectively.Both the eventual average tumor volumes and weights in miR-34a group were lower compared to the other two groups(P<0.05).qRT-PCR results revealed that the expression of miR-34a in miR-34a transfected group was significantly higher than in the other two groups,while the mRNA and protein expression of CDK6 and Bcl-2 were lower than the other two groups ( P<0.05 ) .Conclusion: miR-34a may inhibit the growth of human nasopharyngeal carcinoma CNE-2 cell line subcutaneous xenograft tumor in nude mice by down-regulating CDK6 and Bcl-2.
