ABSTRACT
As a pattern recognition receptor, CD36 antigen participates in a series of pathophysiological processes, and has well been documented in transfusion medicine. This article reviews the discovery, structure and expression of CD36, the type and frequency of CD36 antigen deletion, as well as the relationship between anti-CD36 and transfusion-related immune diseases.

ABSTRACT
Objective To investigate the MRI findings of recurrent supurative colangitis complicated by intrahepatic cholangiocarcinoma and clinical diagnostic value.Methods 264 patients with recurrent suppurative cholangitis who were admitted into the hospital during June 2010 to July 2014 were selected as the research objects.All of the patients were given magnetic resonance imaging(MRI)and surgical pathological examination or biopsy.The Resultsof surgical pathological examination certified that there 43 patients(52 lesions)complicated by intrahepatic cholangiocarcinoma.The results of pathological examination were taken as the golden standard to evaluate the accuracy, specificity and sensitivity of MRI in the clinical diagnosis of recurrent supurative colangitis complicated by intrahepatic cholangiocarcinoma.The MRI findings were analuzed.ResultsAmong the 264 patients with recurrent supurative cholangitis in this group, there were 43 patients(52 lesions)with complicated intrahepatic cholangiocarcinoma confirmed by surgical pathological examination or biopsy, accounting for 16.3% of total number of subjects;MRI results showed that 218 cases were true negative, 41 cases true positive, 2 cases false negative and 3 cases false positive.The diagnostic sensitivity was 95.3%(41/43), specificity 98.6%(218/221)and the accuracy 98.1%(259/264).Conclusion MRI in the diagnosis of recurrent supurative cholangitis complicated by intrahepatic cholangiocarcinoma is of higher accuracy, sensitivity and specificity.MRI findings are obvious.It is worthy of clinical promotion.
ABSTRACT
Objective To research the clinical value between gene polymorphism of human platelet alloantigens (HPA) 1-6, 9, 15 and platelet transfusion refractoriness ( PTR) .Methods Totally 40 patients with platelet transfusion refractoriness( PTR) were randomly selected, and patients and donors’ peripheral blood specimens were collected and tested these samples with platelet GP specific antibodies, and judged the results of platelet transfusion, and with the help of the combination of PCR and direct sequencing for classification of HPA 1-6,9,15 antigens and observe the percent platelet recovery ( PPR ) after the same type of platelet transfusion, and explore the relationship between HPA gene polymorphism and PTR. Results There was no HPA-b gene was found neither on patients and donors’ HPA 1,4,9, showed the distribution of aa homozygous form; HPA 5,6 were mainly aa homozygous form, little bb homozygous form was discorvered.And HPA 2,3,15 were distributed of polymorphism, the frequency of HPA 2,3,5,6,15 were found with polymorphism.Conclusion For these patients who were happened with PRT many times, in addition to taking HLA into account, HPA gene polymorphism are also need to be considered.Most people only need to test patients and donors’ HPA2,3,15 gene to decrease the occurrence of PTR significantly when making HPA matching.
ABSTRACT
Objective To investigate the role of p38 MAPK in the trypsin-induced injury in human esophageal epithelial cells.Methods Primary cultured human esophageal epithelial cells were stimulated with trypsin (20,40,and 80 μg/ml) for4 hours,phosphorylation of p38 MAPK was evaluated by Western blotting.Primary cultured human esophageal epithelial cells were stimulated with trypsin (40 μg/ml) and treated with p38 MAPK inhibitor (SB203580,1 and 10 μmol/L) simultaneously.Four hours later,the cells were collected for analysis.Results Western blotting results revealed that stimulation with trypsin enhanced phosphorylation of p38 MAPK,indicating that trypsin activated p38 MAPK in esophageal epithelial cells.SB203580 treatment suppressed trypsin-induced expression of pro-inflammatory cytokines including interleukin-8 (IL-8),cyclooxygenase 2 (COX2),and tumor necrosis factor alpha (TNFcα).Finally,SB203580 treatment suppressed trypsin-induced upregulation of protein expression of inducible nitric oxide synthase (iNOS),and subsequently reduced nitric oxide (NO) levels.Conclusions The regulation of p38 MAPK was involved in the trypsin-induced injury in esophageal epithelial cells.
ABSTRACT
Objective To analyze the characteristics of gastroesophageal junction(GEJ) in gastroesophageal reflux disease (GERD) using high resolution manometry (HRM),and the features in different GERD subtypes,reflux esophagitis (RE) and non-erosive gastrooesophageal reflux disease (NERD).Methods Sixty GERD patients were divided into two subtypes,RE (n =33) and NERD(n =27),based on the results of endoscopy.All patients received HRM,and were divided into three subtypes,type Ⅰ,type Ⅱ and type Ⅲ according to the GEJ pressure morphology.HRM results among different subtypes were investigated.Results In 60 GERD patients,the GEJ was divided into three subtypes,including 26 cases of type Ⅰ (RE =14,NERD =12),29 cases of type Ⅱ (RE =14,NERD =15) and 5 cases of type Ⅲ (RE =5).The characteristics of GEJ morphologic subtypes were analyzed.The total length of lower esophageal sphincter(LES) of three GEJ subtypes(type Ⅰ,type Ⅱ and type Ⅲ) were (3.35 ± 0.56) cm,(3.29 ± 0.87) cm and(2.43 ± 0.22)cm,respectively.The LES intra-abdominal length of three GEJ subtypes were(2.41 ± 0.68) cm,(3.07 ± 4.59) cm and (0.00 ± 0.00) cm,respectively.The LES rest pressure of three GEJ subtypes were (22.00 ± 8.00) mmHg,(16.46 ± 8.60) mmHg and (11.07 ± 5.80) mmHg,respectively.The total length of LES were significantly different among three subtypes (P ＜ 0.05).The LES rest pressure were not significantly different among three subtypes (P ＞ 0.05).Among type Ⅰ and type Ⅱ patients,there were no significant difference in LES-CD distance,total length of LES,LES intra-abdominal length and LES rest pressure between RE group and NERD group.Conclusion HRM can clearly distinguish the GEJ subtypes.To some extent,esophageal motility characteristics of the patients with different subtypes GEJ is various.However,it still needs further studies with larger sample size to confirm.
ABSTRACT
Objective To study the regional cerebral glucose utilization with 18 F-fluorodeoxyglucose (FDG) PET and to investigate the correlation between cerebral glucose metabolism and the clinical characteristic of progressive supranuclear palsy (PSP).Methods A total of 13 patients with PSP and 30 matched healthy controls were performed 18F-FDG PET imaging at rest state.Visual inspection and statistical parametric mapping (SPM) were used to investigate regional cerebral metabolic rate of glucose (rCMRglc).Results Based on the visual inspection,PET imaging in the PSP patients showed that the focal hypometabolic areas mainly included the bilateral frontal cortex,midbrain and subcortical structures.Compared to the controls,voxel-based analysis showed that the regional glucose metabolism decreased in bilateral superior,middle frontal gyrus,cingulate gyrus,midbrain and subcortical structures including basal ganglion and thalamus,which were consisted with the clinical characteristics,such as vertical gaze palsy,pseudobulbar palsy,postural instability,axial rigidity,dementia and so on.Conclusion 18 F-FDG PET imaging is helpful for the early diagnosis of PSP.
ABSTRACT
Background and purpose: Reports showed that berbefine not only had an effect ofdetoxification and inflammation but also could induce the cell to apoptosis. Berberine may also inhibit the migration and metastasis of tumor. To investigate the effects and mechanism of berberine on migration and metastasis of A549 cells, the proliferation, mobility and adhesion of A549 cells were observed after incubation with berberine. Methods: The proliferation was determined by MTT. Wound healing assay and adhesion test were used to observe the mobility and adhesion rate. The mRNA and protein expressions of MMP2 and MMP9 were assessed by semi-quantitive RT-PCR and gelatin zymography, respectively. Results: Berberine could significantly inhibit the proliferation ofA549 within a certain range of treating time and dose (P<0.05). The mRNA and protein expression of MMP2 and MMP9 gene were decreased slightly by the treatment ofberberine (P<0.05), especially at dose of 100 μg/ml. Conclusion: Berberine can inhibit the migration and adhesion abilities of A549 cells, probably by down-regulating the expression and activation of MMP2 and MMP9.
