1.An analysis of clinical characteristics of autoimmune pancreatitis
Chinese Journal of Internal Medicine 2010;49(11):943-946
Objective To increase the appreciation of manifestations in autoimmune pancreatitis (AIP) and to decrease misdiagnosis rate by investigating the clinical characteristics of AIP. Methods Clinical data were collected and laboratory ,imaging and histopathology were analyzed from the Chinese PLA General Hospital from 1995 to 2009. Patients with AIP were included in the study. Results Eight patients (male 6, female 2) aged 35-69 (52.4 ±9.4) years were diagnosed as AIP from 2006 to 2009. The main clinical manifestations include intermittent jaundice in 6 cases (6/8), abdominal pain in 5 cases (5/8),weight loss in 4 cases (4/8), and accompanied with other diseases of immune system in 4 cases (4/8).The imaging showed head of pancreas enlargement in 3 cases (3/8) and whole pancreas enlargement in 5 cases (5/8). There is a "banana-peel like" ring around the pancreas and irregular stenosis of pancreatic duct. Massive lymphocytes and plasma cells infiltration and parenchymal fibrosis were shown in pancreatic tissues, bile duct,salivary gland and liver in pathology. Clinical manifestations, laboratory examinations and images in 7 cases (7/8) were improved after treatment with prednisone. Twenty-two of them were misdiagnosed as pancreatic or biliary carcinoma and 21 were performed laparotomy in the period of 1995-2005 ( 23 cases). After 2006, however, the misdiagnosis rate significantly decreased from 95.7% ( 22/23 ) to 0. Conclusions AIP seems to be a systemic autoimmune disease rather than an isolated disorder,markedly overlapping with other autoimmune diseases. Definitive diagnosis can be improved by the detection of immune parameters and pathological examination.
2.Study on expression,purification and biological characteristics of recombinant human interferon-epsilon in E.coli
Chinese Journal of Microbiology and Immunology 2008;28(8):749-753
Objective To construct a novel recombinant human IFN-ε,and to analyze its physi-cal,chemical properties and biological characteristics.Methods Human genomic DNA was used as the template to synthesize IFN-ε gene by PCR.The sequence was cloned into plasmid vector pET-32a(+),and the recombinant plasmid pET-32a(+)/IFN-ε was transformed into E.coli BL2l(DE3).The form of ex-pression product was inclusion bodies.After purification and renaturation.high purity active protein IFN-εwas achieved.The final product was tested for its physical.chemical properties and biological characteristics including anti-viral and anti-proliferative acfivities.Results IFN-ε was expressed in inclusion body in E.coli.After the protein renaturation and purification,the purity was more than 95%.The rhIFN-ε protein had a specific anti-viral activity of about 1.2×103 IU/mg.Its anti-poliferative activity is obvious and can in-duce cells to produce anti-viral protein MxA.Conclusion Human IFN-ε protein was expressed successful-ly.and this protein has anti-virus and anti-prolireration activity.
3.Summary of traditional Chinese medicine in the treatment of cutaneous pruritus
International Journal of Traditional Chinese Medicine 2015;37(12):1145-1148
Cutaneous pruritus is a kind ofdermatosis without primary lesions, which only manifested as the symptoms of secondary scratches and scabbing.Through the overview of such aspects of pruritus as definition, pathogenesis, treatment based on syndrome differentiation, patent medicines, the combination therapy, external treatment by Chinese medicine, the Chinese herb fumigation and steaming therapy, as well as daily nursing were summaried.
4.The expression differences and their signiifcance of the relevant receptors in breast cancer
China Oncology 2015;(2):155-160
ER, PR, HER-2 are signiifcant biological markers in guiding the choice of treatment and evaluating clinical prognosis. As the progression of tumor cells, the expressions of these receptors in recurrent tumors may be different from primary tumors. Nowadays clinicians have realized the necessity of receptor detection in the metastatic lesions. This article summarized the current research status on the above issues.

6.Significance of combined detection of serum Cys-C and Hcy in the diagnosis of early renal injury in children ;with diabetes
Chinese Journal of Diabetes 2016;24(7):610-613
Objective To investigate the combined detection of serum cystatin C (Cys‐C ) and homocysteine (Hcy) for the diagnosis of early renal damage in diabetic children. Methods Data of 97 cases of diabetic children were collected in our hospital. According to the levels of 24 hUAER ,diabetic children were divided into <30 mg group (n=34) ,30~299 mg group (n=42) ,and ≥300 mg group (n=21). 40 cases of healthy children were selected as control group (NC). Laboratory indexes were compared among different groups. The critical values of Cys‐C and Hcy in early diagnosis of renal damage were calculated by receiver operating curve (ROC). Results The levels of Cys‐C and Hcy in <30 mg group were significantly higher than in NC group [Cys‐C (1.04 ± 0.26 ) vs(0.79 ± 0.21 ) mg/L ,Hcy (13.09 ± 2.15) vs(8.57 ± 1.24)μmol/L ,respectively ,P< 0.05]. When Cys‐C cutoff point took 1.02 mg/L ,the diagnosis sensitivity for diabetic nephropathy diagnosis was 86.09% and the specificity was 83.28% ,the maximum diagnostic index reached 1.6937 ,ROC area under the curve was 0.841.When Hcy threshold took 13.00 μmol/L ,the sensitivity was 83.98% and the specificity was 79.24% ,with the maximum diagnostic index 1.6322 and ROC area 0.795.Cys‐C combined with Hcy had a sensitivity of 92.38% and a specificity of 89.17% ,with the maximum diagnostic index 1.764 and ROC area 0.928. Conclusion Cys‐C combined with Hcy detection for early diagnosis of renal injury in diabetic children has important clinical value.

Journal of Peking University(Health Sciences) 2004;0(01):-
T)of PTCH2 were identified and 9 polymorphisms (3 of which were novel) were determined in the present series. Conclusion: Although not as frequent as PTCH1 mutations, PTCH2 germline mutations were detectable in a subset of NBCCS patients with KCOTs. The pathogenetic role of these PTCH2 mutations is yet to be clarified.

Parenteral & Enteral Nutrition 1997;0(02):-
The pro-inflammation cytokine is secreted by cells,and the function is to promote and regulate inflammatory reactions.They include IL-1,IL-6,TNF-? and IFN-?.Researchs have revealed that the levels of serum pro-inflammation cytokinemight increase notably in inflammatory bowel disease patients and they could cause the change of intestinal epithelium tight junctions.
