Objective To explore the relationship of vertebral artery hypoplasia (VAH) with acute posterior circulation cerebral infarction (APCCI).Methods One hundred and eighty-nine consecutive patients diagnosed as having acute cerebral infarction admitted to our hospital from March 2015 to March 2016 were enrolled in our study;retrospective analysis was performed on their clinical and radiographic data to compare the general clinical characteristics of patients with posterior circulation infarction (PCI) and anterior circulation infarction (ACI).VAH was conformed by cranial magnetic resonance angiography (MRA),vertebral artery ultrasound or cranial MRA+vertebral artery Ultrasound.The infarction lesions in VAH patients with APCCI were typed;the correlation between vertebral artery diameter's differences and National Institute of Health stroke scale (NIHSS) scores in VAH patients with APCCI was illuminated.Results In 189 consecutive patients with acute cerebral infarction,32 (16.93%) were with VAH;after exclusion of 8 with infarction in both anterior and posterior circulation,90 (49.72%) were in PCI group while 91 (50.28%) in the ACI group.Univariate analysis showed that statistical differences were noted between the two groups in triglyceride (TG) and VAH levels (P<0.05).In 23 patients with APCCI with VAH,brain stem infarction consisted of 9 patients (5 VAHs were ipsilateral to the infarction,3 VAHs contralateral and one bi-VAH),cerebellum infarction consisted of one patient (ipsilateral side),thalamus infarction 10 patients (4 VAHs were ipsilateral to the infarction,and 6 VAHs contralateral),occipital lobe infarction 2 patients (one ipsilateral and one contralateral) and cerebellum with thalamus infarction one patient (the side of VAH was ipsilateral to the cerebellum and contralateral to the thalamus).After excluding one patient with bi-VAH,in 22 patients with APCCI combined with VAH,significantly positive correlation between vertebral artery diameter's differences and NIHSS scores was noted (r=0.560,P=0.000).Conclusions It might be the best assessment standard of VAH measured by combination of transcranial MRA and vertebral ultrasound.TG and VAH may be risk factors of APCCI,and VAH could be one independent risk factor of APCCI.The side of VAH is usually ipsilateral to the brain stem and cerebellum infarction,while contralateral to the thalamus infarction in APCCI patients with VAH.Also,vertebral artery diameter's differences are positively correlated with NIHSS scores.

Objective:To design and implement a network-based quality management system for tumor radiotherapy.Methods:The system consists of B/S framework-based three-layer structures including the application layer, system service layer and data layer. It utilizes Nutz as the development framework to develop web applications, MySQL as the system database, Java programming language for system development, Tomcat as a system application server for project release and IE, Google and other mainstream browsers to achieve client access server functions.Results:The system can support integrated information management and service of quality control institutions at the provincial, municipal and county levels. The functions include procedure management, case management, quality control management, notification announcement, data management and system management, etc. The system has been set up and tested in the cooperation units, and the operation and function are in good condition.Conclusion:The system can support the assessment of online quality control, which is conducive to information analysis and sharing, promotes the standardization and normalization of quality control and improves work efficiency. Case management function can monitor the diagnosis and treatment processes of patients, establish continuous electronic record, deliver rational treatment and rehabilitation guidance plan, which play a pivotal role in the evaluation of tumor radiotherapy.

To observe the protective effect of alpha-mangostin (α-MG) on focal segmental glomurular sclerosis (FSGS) induced by adriamycin.
Methods: Adriamycin nephropathy (AN) model was induced by adriamycin (10 mg/kg) via a tail vein. Then the mice were treated with α-MG (12.5 mg/kg) or normal salin once daily for 6 weeks. At the end of 6 weeks, the mice were sacrificed, and the kidneys and blood samples were collected. Histopathology of the kidneys were analyzed under the optical microscope. The serum levels of biochemical indicators, such as serum creatinine (SCr), blood urea nitrogen (BUN) and cholesterol were determined. The levels of superoxide anion, malondialdehyde (MDA), and glutathione (GSH), the activity of superoxide dismutase (SOD) and catalase (CAT) in kidney tissues were determined. Serum levels of IL-1β, IL-18, IL-10 and adiponectin were determined. The levels of TGF-β1, collagen I (Col I), α-SMA, silent information regulator 1 (Sirt1) and the nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) in kidney tissues were determined using immunohistochemical staining, Western blot, and RT-PCR.
Results: The levels of SCr, proteinuria, urine protein to creatinine ratio and serum cholesterol were attenuated in AN mice after α-MG treatment, while creatinine clearance rate and serum albumin were upregulated (P<0.05). α-MG treatment alleviated the glomerular and interstitial fibrosis, downregulated the expression of fibrosis markers, such as Col I and α-SMA (P<0.05). α-MG treatment reduced the production of superoxide anion, the levels of MDA and GSH, and increased the activity of CAT and SOD (P<0.05). α-MG treatment inhibitd the generation of pro-inflammatory cytokines, such as IL-1β and IL-18 and promoted the production of anti-inflammatory cytokines, such as the IL-10 and adiponectin (P<0.05); α-MG treatment promoted the expression of Sirt1, inhibitd the expression of NLRP3 in kidney tissues (P<0.05).
Conclusion: α-MG could attenuates FSGS of mice induced by adriamycin ameliorate and improve renal function. α-MG exerts its anti-inflammatory and anti-oxidative effects by up-regulation the expression of Sirt1 and suppression of NLRP3.

OBJECTIVETo evaluate the therapeutic efficacy and related risk factors of acute myelogenous leukemia (AML) patients treated with unrelated cord blood transplantation (UCBT).
METHODSA retrospective analysis was performed on the clinical data of 58 AML patients that consisted of 1 case of M0, 1 case M1, 35 cases M2, 3 cases M4, 14 cases M5, 3 cases M6, and 1 case acute mixed leukemia, respectively. Of them, 1 case AML secondary to myelodysplastic syndrome, and 36 in first complete remission (CR1), 14 in second complele remission (CR2), 8 in non- remission (NR), 43 cases were refractory or high-risk patients(70.1%). The median age was 14.5 years with the median weight of 45 kg, 49 patients received sUCBT and 9 dUCBT. All the patients conditioned with intensified myeloablative regimen and received a combination of Cyclosporine A(CsA)and mycophenolate mofetil(MMF)to prevent graft- versus- host disease(GVHD).
RESULTS56 out of 58 patients achieved engraftment with implantation rate 96.6%. The median time of ANC≥0.5×10⁹/L was 17(12-37)days, and that of PLT≥20× 109/L 33(17-140)days respectively. 24 cases developed acute GVHD(aGVHD), the incidence rate of grade Ⅱ to Ⅳ aGVHD was 30.4%. The chronic GVHD(cGVHD)was occured in 7 patients of the 49 evaluable patients, all were limited. The estimated 3-year overall survival(OS)and disease-free survival (DFS)were(60.3±6.4)% and(60.1±6.5)% respectively. And the cumulative incidences of 3-year nonrelapse mortality(NRM)and relapse were 33.3% and 9.1% respectively. The 3- year OS rates of AML patients were(66.0 ± 6.7)% for CR and(25.0 ± 15.3)% for NR, differences were statistical significance.
CONCLUSIONFor AML patients, UCBT was conducive to improve outcome with lower incidences of cGVHD and relapse, the patients after transplantation could obtain high quality of life.
