Objective To estimate the success rate of emergency endoscopic treatment in patients with esophagogastric variceal bleeding using self-made gastroscope outer casing and to investigate bow to prevent complications. Methods A total of 11 patients with esophagogastric variceal bleeding underwent endoscopic treatment with self-made gastroscope outer casing, which consisted of a wire reinforced plastic casing (1.05 cm in inner diameter, 1.35 cm in outer diameter and 50 cm in length), a 3.8 cm×3.8 cm balloon fixed on the casing head and its cavity connected to the gas pipeline placed in casing tail, an anti-reflux pad in the insert entrance of the endoscope tail as well.as a flushing hole. The endoscopy was introduced to the esophagus or stomch together with outer casing to wash and pump the hematocele out from the side of flushing hole. In patients with hemorrhagic lesion in esophageal vein, the balloon was used to press bleeding vein and intravascular sclerotherapy was performed simutanously. In those with hemorrhagic lesion in gastric vein, the balloon was pressed on esophageal vein near to the cardia and intravascular sclerotherapy was performed. Results During the process of examination, the hemorrhagic lesion was fully exposed because of flushing, and bleeding was controlted in all patients after sclerotherapy. No complication such as aspiration or perforation was seen. Conclusions For emergency endoscopic treatment of esophagogastric variceal bleeding, gastroscope outer casing is helpful in removing intragastric hematocele and maintaining a clear field of vision. It can be effectively improving the efficacy of sclerot herapy.

Objective:This study aimed to compare rectal cancer tumor volume parameters measured by MRI sequences (T1WI, T2WI, and DWI) and/or CT with those by pathological specimen. Methods:Twenty-two patients with rectal cancer were prospectively enrolled. MRI sequences including T1WI, T2WI, and DWI, and/or CT of the pelvis were performed before operation. Volume parameters, such as tumor length along the rectal axis, maximum tumor width perpendicular to rectal axis, and tumor actual area in that perpendicular plane, were measured on T1WI, T2WI, DWI, and CT, respectively, for each patient. The respective pathological parameters were further measured in surgical specimen after total mesorectal excision. The two kinds of parameter values measured in imaging and pathology were statistically compared and accuracy appraisal was performed. Results:The mean Lpath-L was 4.06±1.14 cm. The mean LT1-L, LT2-L, LDWI-L, and LCT-L were 3.91± 1.51, 4.62±1.41, 3.39±1.05, and 3.94±1.23 cm, respectively. Correlation coefficients were 0.688, 0.635, 0.688, and 0.720 (P<0.05). An average 6 mm overestimation was found in T2WI, and 1 to 6 mm underestimation in T1WI, DWI, and CT in length values compared with those measured in surgical specimen. The mean Lpath-W was 2.56 ±0.94 cm. The mean LT1-W, LT2-W, LDWI-W, and LCT-W were 3.62±0.99, 3.66±0.76, 3.23±0.58, and 3.64±1.04 cm, respectively. The magnitude of mean overestimation ranged from 5.1 to 11.1 mm. The Apath was 4.30 ±2.83 cm2. AT1, AT2, ADWI, and ACT were 8.98±3.90, 8.99±3.43, 8.41±3.09, and 9.63±4.40 cm2, respectively, which double overestimated the tumor area in the perpendicular rectal plane. Conclusion:The difference in longitudinal length between MRI sequences/CT and pathological specimen was in the range of?6 mm to 6 mm. The mean maximum tumor width and areas in the maximum tumor perpendicular plane were overestimated. This study indicated that gross tumor volume delineation based on CT or MRI for rectal cancer irradiation should be conservative in the axial images of rectum, and meticulous consideration is required along the rectum.

Objective To explore the expression of Metastasis-associated in colon cancer-1 (MACC1) in patients with nasopharyngeal carcinoma (NPC), and its relationship with clinical pathologic characteristics and prognosis Methods The expression of MACC1 was detected in 130 cases of NPC and the relationship among the MACC1 expressions, clinical pathologic characteristics and prognosis of NPC was analyzed. Results Positive expression rate of MACC1was 68.5% in the NPC and MACC1 expression was associated with advanced T stages, lymph node metastasis and advanced clinical stages of NPC (P < 0.05). The results of Kaplan-Meier survival analysis showed that the five year overall survival rate in patients with positive expressions of MACC1 (45.9%) was significantly lower than that of those with negative expressions (73.7%) and the difference was statistically significant (P < 0.05), Cox multi-factor analysis results showed that MACC1 expression was an independent prognostic factor for NPC (P = 0.004). Conclusion MACC1 abnormal expression is closely related to the invasion and metastasis of NPC and it is expected to become a new target for gene therapy of NPC.

Primary central nervous system lymphoma (PCNSL) is a disease with relatively poor prognosis, and radiotherapy is one of the important treatment methods. However, with the widespread application of high-dose methotrexate-based induction chemotherapy regimen and autologous hematopoietic stem cell transplantation consolidation therapy, as well as the impairment of cognitive function after whole brain radiotherapy, the value of radiotherapy has been controversial in the past decade. This article reviews the application of radiotherapy in various treatment stages of PCNSL, the selection of radiotherapy target area and dose, and discusses the value of radiotherapy in the treatment of PCNSL.

Objective: To measure the distance of the lateral, inferior, and superior microfoci from a gross tumor in a pathological speci-men and to provide scientific evidence for margin extension to form the clinical target volume (CTV) in high-dose radiotherapy for rec-tal cancer. Methods: Twenty-eight surgical specimens were collected from patients with rectal cancer who underwent total mesorectal excision (TME) in Hunan Cancer Hospital between October 2016 and April 2017. The nearest distance of the farthest peripheral micro-foci from the gross tumor was measured. The in vivo-in vitro tumor retraction factor (R1) was calculated by measuring the ratio of the tumor's perpendicular depth based on magnetic resonance imaging and immediate surgical specimens. The retraction factor (R2) in the process of pathological specimen makeup was calculated by knot labeling. The distance of microfoci extension was calculated based on that measured in pathological specimens including corrections with R1 and R2 and record as microcarcinoma extension mea-sured in vivo,MEin vivo. Results: Among the 28 pathological specimens, lateral, inferior, and superior microfoci were found in 17 (60.7%), 3 (10.7%), and 0 cases, respectively. The mean R1 was 0.913 and mean R2 was 0.803. The farthest distance measured inferiorly was 28 mm in vivo after correction. The maximum, minimum, and mean measured lateral distances were 12.03 mm, 3.03 mm, and 7.50 mm after correction, respectively. The 95% frequency value was within 10 mm. Conclusions: The lateral microfoci extension was within 10 mm for 95% of the rectal cancer patients. The margin expansion to form the CTV was suggested to be 10 mm for a late-course boost of high-dose radiotherapy for rectal cancer.

BACKGROUNDTo explore the clinical and pathological characteristics and pathogenesis of autoimmunohepatitis (AIH).

METHODSThe serum and liver biopsy specimens and clinical data of 26 cases with patients with AIH were analyzed and scored according to the criteria of International autoimmune hepatitis (IAIHG, 1999). The changes of dendritic cells (DC) in the liver tissues were observed with a panel of DC markers (CD-80/B7-1, CD-86/B7-2, CD-1a and HLA-DR) and immunohistochemistry, and the activation of hepatic stellate cells (HSC) and the expression of TGF-alpha were also detected. Liver tissue specimens from 10 patients with chronic viral hepatitis B and C respectively and 5 normal liver specimens were chosen as controls.

RESULTSMean aggregate scores of 26 AIH cases, including 21 cases of type B (80.8%) and 5 cases of type C (19.2%), which were 18.6 +/- 1.4 and 19.1 +/- 2.1 respectively. There were significant differences between the type B and type C in the average age levels of serum ALT and AST, and alpha-Glo (P <0.001 or P< 0.01 or P <0.05). Histological features of all the AIH liver tissues showed the lesions of chronic active hepatitis such as interface hepatitis/piecemeal necrosis (100%), obvious lobular inflammation (type B 95.2%, type C 100%), bridging necrosis (57.1% type B, 80.0% type C, P<0.05), rosetting of liver cells (71.4% type B, 100% type C, P<0.01), central lobular confluent necrosis (33.3% type B, 80.0% type C, P<0.001), predominant plasmacytic infiltration (type B 95.2%, type C 20.0%, P<0.001). The rates of increased and concentrated DC in the portal and lobular areas, especially in the active lesions in type B and type C AIH were 85.7% (18/21) and 5/5 respectively. It was found that DC and lymphocytes surrounded the hepatocytes which partly expressed HLA-DR antigen, while there were no or a few HLA-DR positive hepatocytes in controls. Meanwhile, the number of alpha-SMA positive HSC and the expression of TGF- were obviously increased in AIH liver tissues.

CONCLUSIONSSeveral clinical and pathological features of AIH were identified in this study. As an antigen-presenting cell, DC might play an important role in the pathogenesis of AIH. In China, sub-type B of AIH might be more frequent than sub-type C and there were differences in clinical aspects, serology and pathology between the two types.
