By now,the mutations of C-KIT gene and PDGFRA have been regarded as the most important primary incidences.The latest results have revealed the fact that the abnormal expressions of p53,p16,p21 WAF-1,p27 and E-cadherin(cDH1) which were labeled as anti-oncogenes in most of human tumors,existed in the progression of gastrointestinal stromal tumor.Therefore,we put forward the theory that gene mutaion may lead to the instability of DNA that further promotes mutation of short tandem repeat in anti-oncogene coding region,on basis of which,that finally lead to the malignant progession of gastrointestinal stromal tumor by anti-oncogene mutation.

Cellular schwannoma is a rare benign tumor of the peripheral nerves.The tumor is consist of spindle cells which arranged in interwoven bundles,and lacking the mesh district and palisading structure.The tumor cells are abundant,with coarse chromatin,deeply stained nuclei and in multiforms.So the tumor may easily be misdiagnosed as various types of spindle cell sarcoma.Intraperitoneal cellular schwannoma may also be mistaken as gastrointestinal stromal tumors.In this article,the clinical characteristics,diagnosis and treatment of cellular schwannoma were analyzed based on the clinical data of a patient with cellular schwannoma in the gastric wall misdiagnosed as gastric stromal tumor.

OBJECTIVETo investigate the therapeutic effects of an early application of Chaiqin Chengqi Decoction (CQCQD) on severe acute pancreatitis (SAP) complicated with acute respiratory distress syndrome (ARDS).
METHODSForty patients of SAP-ARDS were equally randomized into the early-treated group (ET) and the late-treated group (LT), CQCQD was administered to them immediately and 3 days later after hospitalization respectively. Baseline materials in the two groups at the entry were insignificantly different (P > 0.05), and the same conventional Western medical therapy were available to them all. The Acute Physiology and Chronic Heath Evaluation II (APACHE I) scores, the incidence and sustained time of complications, the occurrence of infection, requirement of operation shifting on day 7, as well as the duration resided in hospital and mortality in patients were observed and compared.
RESULTSComparisons of the above-mentioned clinical indexes between groups showed that the APACHE II score was lower (5.1 +/- 2.0 scores vs 9.3 +/- 4.3 scores, P < 0.01); the incidence of shock was lesser (1/20 vs 7/19); the duration of ARDS, renal failure, cardiac insufficiency, hepatic dysfunction, cerebropathy and enteroplegia, as well as the duration in hospital and the requirement of operation shifting were all shorter significantly (P < 0.05) in the ET group than those in the LT group, but no statistical difference (P > 0.05) was shown in terms of the infection incidence and the mortality.
CONCLUSIONAn early application of CQCQD in the treatment of SAP could shorten the duration of complications and the couse of disease, lower the requirement of operation shifting. But further study with large samples for explore its impact on the infection incidence and the mortality is needed.

Antimicrobial peptides, a cluster of small peptides secreted by the majority of creatures, have been demonstrated with activity against a wide range of microorganisms including bacteria, protozoa, yeast, fungi, viruses and even tumor cells. These peptides have some features such as broad spectrum , high effi-cacy and stability, little drug resistance. A lack of new antibiotics combined with emerging multi-drug resis-tance issues demands that new antimicrobial strategies be explored for treating these infections. It has been proposed that the antimicrobial peptides might form the foundation for a new class of clinically useful an-timicrobials. We review the advantages of these molecules in construction features and bioactivity, with the focus on the mechanism and clinical applications.

Objective To investigate the incidence of hearing disorder and analyse the high-risk factors with hearing injury in newborns with hyperbilirubinemia.Methods The newborns with hyperbilirubinemia who admitted to the department of neonate,were received the distortion product otoacoustic emission(DPOAE)test when they recovered from hyperbilirubinemia;those babies who didn′t pass the first test received screening again in 42 days after birth.Those babies who didn′t pass the second test received auditory brain stem response(ABR)test.Results Fifty-eight(33.2%)newborns didn′t pass the first DPOAE test among 235 newborns with hyperbilirubinemia;11(18.9%)infants didn′t pass the second DPOAE test among 58 infants;5 infants failed to pass the ABR test,the ratio of hea-ring disorder in newborns with hyperbilirubinemia was 2.13%;18(9.9%)newborns didn′t pass the first DPOAE test among 182 normal newborns,and those infants all passed the second DPOAE test.Conclusions Hyperbilirubinemia is high-risk population of hearing disorder.The congenital cytomegalovirus infection,neonatal septicemia and hemolytic disease of newborn are the high risk factors responsible for hearing disorder.All high risk newborns should recieve hearing examination regularly.

OBJECTIVETo investigate DNA aneuploid and P16 expression in biopsy specimens from lung cancer, and to study genetic instability and the application of flow cytometry in lung cancer pernicious degree diagnosis.
METHODSBlood cells and cancer cells in biopsy specimens were marked simultaneously with anti-CD45 and anti-P16 fluorescent antibody, and the ratio of CD45+ P16+ cells and CD4- P16+ cells was compared. DNA content in biopsy specimens from lung cancer was detected by flow cytometry.
RESULTSAmong the 74 cases of lung cancer, there are 46 cases of DNA aneuploid (62.2%). Thirty-seven cases of lung cancer expressed P16 lowly (50%). Twelve cases of lung cancer only expressed P16 lowly (16.22%), 21 cases of lung cancer only expressed DNA aneuploid (28.38%), and 25 cases not only expressed P16 lowly but also expressed DNA aneuploid (33.78%). Indexes of malign degree, such as P16 low expression or DNA aneuploid could be detected in 58 cases among the 74 cases (78.38%) by flow cytometry.
CONCLUSIONP16 low expression and DNA aneuploid are the indexes of lung cancer malign degree, and flow cytometry can be used to study genetic instability and evaluate biopsy specimens from lung cancer.
