The study process of TCM syndrome spectra of hemopathy is the process to recognize the syndrome characteristics of the onset, development of hemopathy, it bases on norm of TCM symptoms and syndrome. In this course, it could not only find common feature of syndrome,but also analyze distribution regularity of TCM syndrome. Thus to establish sequence of hemopathic syndrome, and to provide the basis for clinic determination of treatment based on syndrome differentiation, and provide the foundation for finding correlation of TCM syndrome and target tests.

Discuss the pathogenesis and treatment strategy of idiopathic thrombocytopenic purpura from the view of insidious pathogenic factors.The invasion,remission and recurrence of ITP implicated the theory model of insidious pathogenic factors,and it applied new thread for syndrome differentiation and treatment.

Objective To study the relationship between the positive expression of human leukocyte antigen B27 (HLA-B27) in different age groups and genders in Uygur and Han nationality in Xinjiang,and explore the clinical value of HLA-B27 in different ethnic groups.Methods From January 2013 to November 2016,1 416 cases of Uygur and Han patients with positive expression of HLA-B27 were detected by flow cytometry.There were 369 cases of Uygur and 1 047 cases of Han.Results Independent samples t-test showed that the positive expression of HLA-B27 in Uygur and Han population was statistically significant (165.22±8.262 vs 163.99±8.113,t=2.479,P=0.013).In male,there was a significant difference in the positive expression of HLA-B27 between Uygur and Han population (165.40 ± 8.237 vs 163.99 ± 8.164,t =2.187,P =0.029).In the age of 41～60 years old and ＞60 years old,the positive expression of HLA-B27 in Uygur was higher than that in Han nationality (166.18 ± 7.650 vs 164.53 ± 8.018,t =2.215,P =0.027;171.63 ± 8.134 vs 167.40 ± 9.469,t =2.126,P=0.035).There was no significant difference in the positive expression of HLA-B27 between Uygur and Han nationality in women,as well as in the age of 20 years and 21～40 years (t=-0.029～1.257,all P＞0.05).Conclusion The investigation showed that the positive expression of HLA-B27 in Uygur was higher than that in Han nationality.The content of HLA-B27 positive expression has racial difference.

This study examined the correlation between osteoporosis and the degeneration of intervertebral discs. Sprague-Dawley rats were maintained up to 22 or 28 months. The femoral bone, tibial bone and lumbar vertebra were histologically studied and the expression of collagen type II and X in intervertebral discs was immunohistochemiscally determined. Several indices for the degeneration of intervertebral discs and osteoporosis and the correlation among them were then analyzed. Close correlations were found among the indices for the degeneration of intervertebral discs, including the relative area of the vascular bud, the ratio of the uncalcified and the calcified layers, the expression of collagen type II and X. The correlation with collagen type X was negative. There existed positive correlations among the indices for osteoporosis, including the thickness ratio of cortical bone, the relative area of bone trabecula, the density of femoral and vertebral body bones, and the maximum stress and strain on bone. Analysis on the relationship of osteoporosis and the disease on disc showed that the indices of osteoporosis were negatively correlated with the indices of the degeneration of intervertebral discs but the expression of collagen type X was positively correlated, with the density of vertebral body bones having the strongest dependence on collagen type X. The maximum stress and strain bore no correlation with the degeneration of intervertebral discs. These results suggest that osteoporosis was negatively correlated with the degeneration of intervertebral discs.

Objective This study is to summarize the experience of microsurgical reconstruction for donor liver anatomical variations of hepatic arteries in orthotopic liver transplantation. Methods During the bench surgery, the anatomy of donors′ hepatic arteries was carefully examined and microsurgical techniques were used for the anomalous arteries. The graft arterial flow was checked by Doppler ultrasound daily in the first week in postoperative period and periodically thereafter. Results The arterial anatomy was anomalousin 20 out of 141 (14%) donor livers. Nine cases (6.3%) needed arterial reconstruction. In these cases, 7(4.9%) aberrant right hepatic arteries originating from superior mesenteric artery were anastomosed to gastro-duodenal arteries and another two aberrant hepatic left or right arteries were anastomosed to the stump of the donor splenic arteries. Conclusions The variations of hepatic arteries in donors are common. To obtain the ideal arterial supply of liver graft, both careful checking on the origin of donor's artery and appropriate plastic performance with refined microsurgical techniques are necessary.

Objective To explore the findings of diaphysial osteosarcoma in long bone on X-ray,CT and MRI, and discuss their clinical features and manifestations for differential diagnosis. Methods Twenty-eight cases with diaphysial osteosarcoma in long bone proved by surgery and pathology were reviewed retrospectively. Eighteen tumors were located in the femur, 4 in fibula, 4 in humerus and 2 in tibia. All of the patients were examined by X-ray, CT and MRI. The imaging manifestations on X-ray, CT and MRI were analyzed, and the relationship of the imaging features with the pathological types was also observed. The imaging signs were correlated with the pathologic findings with a double blind method. Results Of the 28 cases, there were 16 cases with large bone destruction, 22 cases with periosteal reaction on X-ray and CT. On X-ray, 18 cases showed soft tissue mass and 12 cases with neoplastic bone and tumor calcification.While on CT, 22 cases showed soft tissue mass on plain scan and 2 more cases displayed soft tissue mass after the injection of contrast mediun. Sixteen cases showed neoplastic bone and tumor calcification on CT.On MRI, there were 10 cases with bone destruction and periosteal reaction with iso- and hypo-intense on T1WI and iso- signals on T2WI. Twenty-six cases showed soft tissue edema and bone marrow on MRI. The soft mass were iso-signals on T1 WI and iso-hyperintense signals on T2 WI or STIR. The soft tissue edema was found hyperintense signals on T2WI or STIR. The lesions had heterogeneous enhancement especially in bone marrow with edema and adjcent soft tissue. Conclusion The X-ray, CT and MRI can reflect the pathological changes of diaphysial osteosarcoma in long bone from different aspects. Lower incidence, large bone destruction and no pathological fracture were the features of diaphysial osteosarcoma. The osteogenic type is diagnosed easily, but the osteolytic lesion should be differentiated from Ewing sarcoma, malignant giant cell tumor of bone and so on.

Objective To assess the significance of the right paraesophageal node(Ⅵb area) dissection in cN0 stage papillary thyroid microcarcinoma(PTMC)central lymph node dissection.Methods The clinical data of three hundred and five cN0 PTMC patients who underwent radical thyroidectomy from 2010 to 2015 was retrospectively analyzed.The metastasis rate of central compartment(Ⅵa area.Ⅵb area)and the clinical data were collected and analyzed.Results 305 cN0 stage PTMC patients underwent total thyroidectomy and bilateral central compartment dissection or right lobectomy combined with ipsilateral central compartment dissection,the mean diameter of the tumors was 6.75 mm.The incidence rate of central compartment metastasis was 35%.The incidence rate ofⅥb area metastasis was 11.1%.The status ofⅥb area metastasis was correlated with major clinicopathologic parameters such as sex,age<45,tumor diameter≥0.8 cm,bilateral multiple lesions, capsule invasion,VI a lymph node metastasis≥3 were all related risk factors of PTMC VIb area metastasis(χ2=6.913,4.241,4.517,5.185,12.400,34.745,P<0.05).Conclusion Because of the high rate of central lymph node metastasis in patients with PTMC and the poor efficiency in the evaluation for central lymph node metastasis before operation,the right paraesophageal lymph nodes(Ⅵb area)dissection is needed to be done in cN0 stage PTMC patients with tumor size≥0.8 cm,multifocal lesions,membrane invasion,Ⅵa area metastasis≥3,especially male patients.

DNA double-strand break (DSB) is the most severe form of DNA damage, which is repaired mainly through high-fidelity homologous recombination (HR) or error-prone non-homologous end joining (NHEJ). Defects in the DNA damage response lead to genomic instability and ultimately predispose organs to cancer. Nicotinamide phosphoribosyltransferase (Nampt), which is involved in nicotinamide adenine dinucleotide metabolism, is overexpressed in a variety of tumors. In this report, we found that Nampt physically associated with CtIP and DNA-PKcs/Ku80, which are key factors in HR and NHEJ, respectively. Depletion of Nampt by small interfering RNA (siRNA) led to defective NHEJ-mediated DSB repair and enhanced HR-mediated repair. Furthermore, the inhibition of Nampt expression promoted proliferation of cancer cells and normal human fibroblasts and decreased β-galactosidase staining, indicating a delay in the onset of cellular senescence in normal human fibroblasts. Taken together, our results suggest that Nampt is a suppressor of HR-mediated DSB repair and an enhancer of NHEJ-mediated DSB repair, contributing to the acceleration of cellular senescence.
