Objective To investigate and analyze the related factors about the occurrence of thyroid diseases induced by interfer‐on in treating the chronic hepatitis B .Methods A retrospective analysis and following up of 213 interferon‐treated patients with chronic hepatitis B were performed .They were treated for 48 weeks and Logistic regression analysis was performed to evaluate the risk factors of thyroid dysfuncion .Patients were followed up for 48 weeks after drug withdrawal .Results In 213 patients received interferon therapy ,there were 38 cases suffered thyroid dysfunction ,nine of which were hypothyroidism including six cases of Hashimoto′s disease and 3 cases of non‐autoimmune thyroid dysfunction ,six of which were hyperthyroidism including 3 cases of Grave disease and 3 cases of destructive thyroiditis ,five of which were subclinical hyperthyroidism and 18 of which were subclinical hypothyroidism .Until 48 weeks of following‐up after treatment ,all patients with thyroid function was normal .Logistic regression a‐nalysis showed that the risk factors of female(OR=3 .696) ,hepatitis C virus infection over the same period (OR=3 .675) and pre‐stored anti‐thyroid peroxidase antibody(OR=2 .008) were correlated independently with the suffering of interferon induced thyroid diseases in the chronic hepatitis B patients .Conclusion For patients with chronic hepatitis B virus using interferon therapy ,espe‐cially the woman who pre‐stored anti‐thyroid peroxidase antibody in a large number and infected with hepatitis C virus ,the clinical therapy should monitor the related index of thyroid function regularly to prevent the happening of thyroid diseases .

Objective To discuss the appropriate timing of providing enteral nutrition through nasojejunal tube for patients with severe craniocerebral injury.Methods 126 cases of patients were divided into 3 groups randomly,providing enteral nutrition through naso-jejunal tube for the first group,the second group and the third group within 12～24 hours,48 hours later and 72 hours later after injury respectively.The nutrition situation of 3 groups was recorded 6 hours later,48 hours later,on the 5th day and the 10th day,including indicators such as total serum protein,blood albumin,serum creatinine,etc and complication cases of diarrhea,hemorrhage of digestive tract,palirrhea,aspiration,inhalation pneumonia and so on within 2 weeks after injury.Results In terms of indicators of albumin,creatinine 48 hours after injury and total protein,albumin and creatinine on the 5th day and 10th day,the first group were better than the second and third group,there were statistic differences between the three groups.Complication comparison within 2 weeks after injury:the difference of palirrhea cases among the three groups was significant,the third group had a higher ratio than the first and second group.And there was no statistic difference in the other indicators like diarrhea,hemorrhage of digestive tract,aspiration and inhalation pneumonia.Conclusions It is high time that patients with simple severe craniocerebral injury are provided with enteral nutrition through naso-jejunal tube within 12 to 24 hours,which can improve patients nutrition situation without the increase of the complications.

To investigate the pathogenesis of Broca-like and Wernicke-like conduction aphasia. Methods 7 cases with Broca-like aphasia (Group A), 7 cases with Wernicke-like aphasia (Group B) and 10 healthy volunteers (Group C) participated in the study. Broca'sarea, Wernicke's area, and the arcuate fasciculus were analyzed by diffusion tensor imaging, and their fractional anisotropy (FA) weremeasured and compared; The fiber construction of Broca's and Wernicke's areas were also compared by diffusion tensor imaging-fibre tractography.Results In Group C, All of the FA was higher in the left hemisphere than in the right hemisphere (P<0.05); In Group A, the FA ofthe Broca's area and anterior segment of the arcuate fasciculus were less in the left than in the right hemisphere (P<0.05)； In Group B, theFA of the Wernicke's area and posterior segment of the arcuate fasciculus were less in the left than in the right (P<0.05). Conclusion Conductionaphasia results not only from arcuate fasciculus destruction, but also from disruption of the associated cortical area. A lesion involvingBroca's area and the anterior segments of the arcuate fasciculus would lead to Broca-like conduction aphasia, whereas a lesion involvedWernicke's area and posterior segments of the arcuate fasciculus would lead to Wernicke-like conduction aphasia.

Objective To study the clinicopathologic features and explore the potential prognostic factors of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma).Methods 86 patients diagnosed with MALT lymphoma were retrieved and divided into 2 subgroups according to the location of tumor,namely gastric (32 cases) and non-gastric (54 cases) subgroup.Histological characteristics were reassessed on hematoxylin-eosin staining slides,and immunophenotypic features were determined by immunohistochemical staining.Interphase fluorescence in-situ hybridization (FISH) was carried out to detect the cytogenetic abnormalities.Results There were no significant difference of clinical behavior,histology,and immunophenotype between gastric and non-gastric subgroups.In addition,FISH detected t(14;18) in 9 ％ (4/45) and t(11;18) in 12 ％ cases (6/50) respectively.Among the 20 cases treated with H pylori (HP) eradication,a significantly lower remission rate was observed in cases with bcl-10 (20 ％) nuclear expression or those harboring t(11;18) (33 ％) compared with those in the negative group (73 ％,91％)(x2 =3.842 and 4.639,P =0.035 and 0.031,respectively).For the 35 non-gastric patients with follow-up data,males (35 ％) and patients older than 60 yrs (25 ％) tended to have a lower remission rate as compared to females (60 ％) and those younger than 60 yrs (63 ％) (x2 =3.905 and 7.373,P =0.048 and 0.007,respectively).Moreover,progression-free survival rate was significantly lower in patients with higher stage (ⅢⅣ) (25 ％) and without t(14;18) (50 ％) than that in patients with stage Ⅰ-Ⅱ (52 ％) and with t(14;18)(75 ％).The differences had statistical significance (x2 =4.207 and 4.363,P =0.040 and 0.037,respectively).Conclusion MALT lymphoma in general is an indolent B-cell non-Hodgkin’ s lymphoma which more frequently occurs in the elderly people.Differences in the response to treatment or the prognosis are observed between gastric and non-gastric MALT lymphoma patients.

Objective To evaluate clinicopathologic features and prognosis of primary gastric anaplastic large cell lymphomas (ALCL).Methods Clinical data and parafiin blocks of 4 patients diagnosed with primary gastric ALCL were obtained. The diagnosis of all cases was based on the criteria of WHO classification of hematolymphoid neoplasm.Furthermore,chromosomal rearrangement involving ALK gene was detected by interphase fluorescence in situ hybridization (FISH) and Epstein-Barr virus (EBV) status was determined by in situ hybridization(ISH) for EBV-encoded small RNAs (EBERs).Results The patients (3 males and 1 female) were from 27 to 87 years old, with a median age of 58.5 years. All the four cases presented with a solitary ulcerative mass in stomach. Morphologically, the normal architecture of gastric wall was effaced by the diffuse infiltration of tumor cells in which the characteristic hallmark cells were easily identified.The tumor cells of all cases showed a consistently strong expression of LCA and CD30,and CD3e was expressed in 3 of the 4 cases.Both ALK expression and ALK gene rearrangements were negative in all cases.Two cases underwent total or partial gastrectomy followed by CHOP chemotherapy. Another one patient was treated with chemotherapy and autologous stem cell transplantation. None of these 3 patients developed a relapse or progression till the last follow-up on Nov 30,2011. While the rest one patient refused to take any treatment and died 20 months after diagnosis. Conclusions Primary gastric ALCL is very rare and usually ALK negative. Its pathologic features as well as the clinical outcome are quite similar to the ALK negative ALCL from other sites, except the more frequently positive CD3e Early diagnosis and proper therapy are of great significance to the prognosis.

OBJECTIVETo study the clinicopathologic features, differential diagnosis and prognosis of primary bone anaplastic large cell lymphoma(ALCL).

METHODSTwelve patients diagnosed with primary bone ALCL were retrospectively reviewed. The clinicopathologic features, immunohistochemic findings and results of in situ hybridization for EB virus were analyzed.

RESULTSOf the 12 patients, the male-to-female was 7: 5 with a median age of 17.5 years (range from 9 to 64 years). Bone pain was the presenting symptom in all patients. Radiographic examination demonstrated solitary osteolytic lesion in 8 patients and multiple lesions in the rest 4 patients. Spine (7 cases) was the most common site to be involved, followed by ilium (5 cases), sacrum (2 cases), humerus (1 case) and collarbone (1 case). Ten patients were available with the follow-up data including 5 ALK-positive and 5 ALK-negative patients, and the follow-up time was 2 to 47 months. Interestingly, the 3 dead patients were ALK-negative whereas 5 of 7 ALK-positive patients achieved remission.

CONCLUSIONSPrimary bone ALCL is a rare type of non-Hodgkin lymphoma and it more frequently involves the axial skeleton. Boys and young males are more commonly affected. Patients usually present at an early stage and have a relatively favorable prognosis. Expression of ALK protein may be associated with a favorable prognosis in primary bone ALCL.

OBJECTIVETo investigate the clinicopathologic features of adult-onset autoimmune enteropathy (AIE).

METHODSA case of adult-onset AIE was described along with a literature review.

RESULTSA 41-year-old male patient was admitted for intractable diarrhea for more than three months despite of any dietary restriction or anti-inflammatory therapy. Fat globule was observed by stool examination and Sudan III staining of the stool was positive. Enteroclysis showed weak movement and few plica of small intestine, while colonoscopy appeared normal. Small bowel biopsies revealed villus atrophy and increased crypt apoptotic bodies and lymphocytic infiltration in deep crypt. Although without significant surface intro-epithelial lymphocytosis, there were a large number of monocytes, lymphocytes, plasmacytes and neutrophilic granulocytes infiltrating in the lamina propria. Morphologically, the colonic mucous was similar to the small intestine although cryptitis and crypt abscess were significant in the former. Serum IgG anti-goblet cell antibody was demonstrated by indirect immunofluorescence. Other causes of diarrhea were excluded on the base of medical history, histopathology and other accessory examinations before the diagnosis of AIE was made. The patient had a complete remission after steroid treatment without recurrence for eight months during the follow-up even after steroid withdrawal for five months.

CONCLUSIONSAIE is exceedingly rare and timely diagnosis is important for successful therapy. Histological differential diagnoses should include ulcerative colitis, celiac disease, lymphocytic colitis, etc. The final diagnosis should be based on histological examination combined with the patient history, clinical manifestation, endoscopy finding and serological testing.

Objective:To review the clinicopathological characteristics and analyze the prognostic factors of hepatoid adenocarcinoma of stomach(HAS).Methods:From August 2012 to June 2017,30 patients with HAS were diagnosed in Daycare of Peking University Cancer Hospital.Clinicopathological data and follow-up information of these patients were retrospectively collected and analyzed.Re-sults:The median age of these 30 patients was 58 years at diagnosis,with a male-to-female ratio of 2.75:1.Twenty-nine patients were confirmed to have lymph node metastases and 7 patients had distant metastases.Ten patients died because of the cancer within the follow-up period.The 1-and 3-year survival rates were 60% and 52%,respectively.Cox multivariate regression revealed that elevated serum CA199 levels,higher lymph node staging,not having undergone radical surgery,and stronger immunohistochemical(IHC)stain-ing intensity of alpha fetoprotein(AFP)were independent poor prognostic factors.Conclusions:Elevated serum CA199 levels,lymph node staging,and IHC staining intensity of AFP are verified in this study as independent risk factors of poor outcome in HAS patients. Early detection and diagnosis of the disease may improve the clinical prognosis.Multidisciplinary team discussions are important in making therapy decisions and radical surgery should be performed whenever possible.
