Objective To investigate the prognostic factots by analyzing clinicopathologlcal characteristics of 972 cases of colonic carcinoma. Methods Clinical and pathological data of 972 patients with colonic carcinoma treated surgically were studied by univariate and multivariate analysis,survival rate was calculated by life-table method and compared by Log-rank test. Results The univariate analysis indicated that the predictors of survival were age,perioperative blood transfusion, perioperative carcinoembryonic antigen(CEA)level,tumor gross type,depth of tumor invasion,lymphatic invasion,liver metastasis,extrahepatic metastasis,local recurrence、peritoneal seeding,pathological type,TNM stage and type of lymph node clearance.The multivariate analysis indicated that the independent predictors of suivival were age,periopemtive CEA level,tumor gross type,lymphatic invasion,liver metastasm,extrahepatic metastasis,local recurrence、peritioneal seeding,pathological type,type of lymph node clearance and TNM stage. Confclusions Lymphatic invasion is the most important independent prognostic factor of patients with colonic carcinoma treated surgically.

Objective To examine HOXA11,ER and PR expression in human endometrial hyperplasia and adenocarcinoma.Methods The immunohistochemistry was applied to analyze the level of HOXA11、ER and PR expression in the proliferative endometria,simple hyperplasia and endometrial adenocarcinoma.Results The expression level of HOXA11 in the endometrial hyperplasia and adenocarcinoma was significantly higher than that of proliferative endometrium(P

Objective To observe the resection of the scapholunate interosseous ligament (SLIL)and its subregions on the three-dimensional(3-D)movement of the scaphoid and lunate so as to discuss the role of SLIL in the 3D flexion-extension motion of the scaphoid and lunate.Methods Twelve upper extremities(six left extremities and six right extremities)from adult cadaver were used in this study and divided into five groups:normal group,proximal subregion resection group,proximal subregion plus dorsal subregion resection group,proximal subregion plus palmar subregion resection group and whole SLIL resection group.The 3-D laser scan and reconstruction technique were used for meusure ment of the 3-D flexion-extension motion of the scaphoid and lunate.Results In the normal group,the scaphoid and lunate flexed and the radial deviated at the same direction during wrist flexion-extension motion.At the same time,there was minimal scaphoid and lunate pronation-supination during wrist flexionextension.After resection of the proximal and palmar(or dorsal)subregions of the SLIL,some different movements were found compared with the normal specimen.Whole SLIL resection resulted in increase of the flexion motion of the scaphoid but decrease of the palmar flexion of the lunate.Conclusions 3-D laser scanning and image reconstruction techniques can accurately measure the 3D motion of the scaphoid and lunate.Partial or whole resection of SLIL may exert significant effect on the flexion-extension motion of the scaphoid and lunate.However,the proximal subregion of SLIL has no prominent effect on the motion of the scaphoid and lunate.

Objective To detect serum oxytocin and highly sensitive C-reactive protein (hs-CRP) levels in obese and type 2 diabetes mellitus(T2DM) subjects and investigate the relationships between serum oxytocin levels and hs-CRP, glycolipid metabolism, insulin resistance and pancreas β cell function. Methods A total of 176 subjects were enrolled in the study, including 88 patients with newly-diagnosed type 2 diabetes ( T2DM) and 88 subjects with normal glucose tolerance(NGT). NGT and T2DM groups were further divided each into normal weight (NW) and obese(OB) subgroups. Obesity was defined as body mass index(BMI)≥25 kg/ m2 according to the WHO-Western Pacific Region diagnostic criteria (2000). 75g oral glucose tolerance test ( OGTT) was performed in all subjects. Fasting plasma glucose ( FPG), 2 h postprandial plasma glucose (2hPG), fasting insulin ( FINS), 2h postprandial serum insulin(2hINS), HbA1C and lipids were also determined. Insulin resistance and pancreas β-cell function were determined by homeostasis model assessment ( HOMA-IR, HOMA-β). Highly sensitive C-reactive protein(hs-CRP) level was determined by chemiluminescence immunoassay and fasting serum oxytocin level was determined by ELISA. Results Serum oxytocin level was lower in T2DM group than that in NGT group(P<0. 01), while serum hs-CRP level was higher in T2DM group than that in NGT group(P<0. 01). The level of serum oxytocin in subjects with obesity was also lower than that in subjects with NW in both NGT and T2DM groups [7. 16(6. 45-8. 82) vs 7. 98(7. 03-9. 17) ng/ L and 9. 23(8. 16-10. 36) vs 9. 86(8. 77-12. 06) ng/ L, P<0. 05]. The level of serum hs-CRP in subjects with obesity was higher than that in subjects with NW in both NGT and T2DM groups [0. 99(0. 25-1. 97) vs 0. 54(0. 19-0. 91) mg/ L and 3. 47(1. 63-6. 20) vs 1. 65(0. 81-3. 81) mg/ L, P<0. 05]. Serum oxytocin level was negatively correlated with hs-CRP, BMI, WC, WHR, HbA1C , FPG, 2hPG, FINS, 2hINS, total cholesterol, triglycerides, LDL-C and HOMA-IR, while was positively correlated with HOMA-β(P<0. 05). Subjects within the upper serum hs-CRP tertile had lower level of oxytocin when compared to subjects in the middle or lower serum hs-CRP tertiles(P<0. 05 ). Conclusion Serum oxytocin level was decreased in subjects with type 2 diabetes as well as with obesity. Serum oxytocin level was closely correlated with inflammation, glycolipid metabolism, insulin resistance, and pancreas β cell function. It may play an important role in the pathogenesis of obesity and T2DM.

OBJECTIVE: To assess the influence of FLT3 expression on the prognosis of patients with acute myeloid leukemia (AML) by cell experiment and clinical data analysis. METHODS: Models for FLT3 over-expression and interference-expression in AML cells were constructed. The level of BAK gene expression and its protein product was determined, along with the proliferation and apoptosis of leukemia cells. FLT3 gene expression and FLT3-ITD variant were determined among patients with newly diagnosed AML. RESULTS: Compared with the interference-expression group, the level of BAK gene expression and its protein in FLT3 over-expression AML cells was significantly lower (P < 0.001), which also showed significantly faster proliferation (P < 0.001) and lower rate of apoptosis (P < 0.001). The expression level of FLT3 gene among patients with newly diagnosed AML was also significantly higher compared with the healthy controls (P < 0.001). The FLT3 gene expression of FLT3-ITD positive AML patients was higher than that of FLT3-WT patients (P = 0.002). Survival analysis showed that AML patients with high FLT3 expression in the medium-risk group had a lower complete remission rate and overall survival rate compared with those with a low FLT3 expression (P < 0.001). CONCLUSION Over-expression of FLT3 may influence the course of AML by promoting the proliferation of leukemia cells and inhibiting their apoptosis, which in turn may affect the prognosis of patients and serve as a negative prognostic factor for AML.

Objective:To explore the impact of home enteral nutrition (HEN) on the treatment strategy of patients with high position intestinal fistula.Methods:The clinical and follow-up data of 36 patients with high position intestinal fistula requiring HEN treated in Beijing Tsinghua Changgung Hospital from Jan 2021 to Sep 2023 was retrospectively analyzed.Results:Among the 36 cases, 2 had indwelling nasogastric tubes, 12 had indwelling nasojejunal nutritional tubes, and 22 had percutaneous jejunostomy. The incidence of HEN-related complications in patients was 13.9%, and there were no serious catheter complications.During HEN, high position intestinal fistula healed in 19 cases (52.8%), returned to the hospital for the next stage of intestinal fistula treatment in 11 cases (30.6%), needed to return to the hospital for nutritional support in 1 case (2.8%), and intestinal fistula aggravated to terminate HEN in 2 cases (5.6%).Conclusion:Under the management of professional team, HEN via nasogastric/jejunal nutritional tube or percutaneous jejunostomy is safe and feasible in patients with high intestinal fistula.

Objective: Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is a recently recognized high-risk T lymphoblastic leukemia subgroup. The optimal therapeutic approaches to adult patients with ETP-ALL are poorly characterized. In this study, we explore the efficacy and outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for ETP-ALL. Methods: The clinical data of 23 patients with ETP-ALL receiving allo-HSCT from 2010 to 2018 were retrospectively analyzed. Patients with ETP-ALL were diagnosed based on the characteristic immunophenotypes. Second-generation sequencing was done in all patients. As to the donors, 12 patients had haploidentical donors (Haplo-HSCT) , 7 HLA-matched sibling donors (Sib-HSCT) and 4 HLA-matched unrelated donors (URD-HSCT) . Before transplantation, 19 patients achieved complete remission (CR) and 4 patients without. Results: The main clinical features of ETP-ALL included high white blood cell counts in 5 patients, splenomegaly in 14, lymphadenopathy in 19, and thymus masses in 5. According to cytogenetic and molecular characteristics, 11 patients had gene mutations related to myeloid tumors, and 7 with high risk Karyotype. After first induction regimen, 14/23 patients achieved CR. 5 patients reached CR after more than 2 cycles of chemotherapy, while another 4 patients did not reach CR. After allo-HSCT, 22 patients were successfully implanted. The median time of granulocyte and platelet reconstitution was +12 and +19 days. One patient died of transplant-related infection at +14 days. The estimated 18-month overall survival (OS) and relapse-free survival (RFS) rates were (55.0±14.4) % and (48.1±14.7) % respectively. Transplant-related mortality was 4.3%. The median OS in patients achieving CR before transplantation was 20 months, however, that in patients without CR was only 13 months. OS and RFS between haplo-HSCT and sib-HSCT were comparable (P=0.460 and 0.420 respectively) . Conclusions Allo-HSCT is an effective therapy in some patients with ETP-ALL. Salvage HSCT cannot overcome the poor outcome. Haplo-HSCT and sib-HSCT in ETP-ALL patients have the similar clinical outcome.
