Objective To investigate the anti-apoptosis effect of transgiutaminase 2 (TG2)in osteosarcoma cell line MG-63 and to explore the mechanism of inhibiting apoptosis of tumor cells.Methods The TG2-tgrgeted siRNA was designed,and the hypoxia culture model of MG-63 cells was established by a hypoxia incubator and the cells were divided into four groups:normal oxygen group,the cells were cultured under normal oxygen;hypoxia group, the cells were cultured in hypoxic incubators;control siRNA hypoxia group,the cells were cultured in hypoxic incubators after transfection of control siRNA;TG2 siRNA hypoxia group , the cells were cultured in hypoxic incubators after transfection of TG2 siRNA.The expressions of Bax and cytochrome C (Cyt C)and the apoptotic rates were observed at different time (6,12,24,48,and 72 h)after hypoxia culture.Microtiter plate assay was performed to monitor the intracellular TG2 activity.RT-PCR was used to detect the mRNA expressions of TG2 and Bax.The expressions levels of TG2,Bax and Cyt C were observed by immunohistochemical staining and Western blotting method.The apoptotic rates were analyzed using flow cytometry.Results Compared with normal oxygen group,the activity of TG2,the mRNA and protein expression levels of TG2 in hypoxia group and control siRNA hypoxia group were increased remarkably with the prolongation of the hypoxia time (P<0.01);the expression level of Bax protein was decreased significantly (P<0.01 ), but the expression level of Bax mRNA had no significant change (P>0.05);the expression levels of Cyt C protein in cytoplasm and mitochondria and the apoptotic rates had no markedly changes (P>0.05).Compared with hypoxia group and control siRNA hypoxia group,the expression levels of mRNA and protein of TG2 in TG2 siRNA hypoxia group were decreased significantly at different time points (P<0.01);the protein expression levels of Bax and Cyt C in cytoplasm and the apoptotic rates were increased markedly (P<0.01 );the expression level of Cyt C in mitochondria was decreased (P<0.01).Conclusion TG2 can inhibit the apoptosis of tumor cells through down-regulating the Bax expression and preventing Cyt C releasing into the cytoplasm.

Abstract: Objective　To investigate the growth and development of HIV-infected children initiating antiretroviral therapy (ART) and its influencing factors. Methods　This retrospective cohort study was conducted in Guangxi. HIV-infected children initiating free antiretroviral therapy (ART) from 2004 to 2019 were included. Z-score was calculated according to the Chinese Child Growth and Development Standard, the Cox-Stuart test was used for trend analysis, and the generalized estimating equation was used to analyze HAZ (Height-for-age Z-score)≥-2 and WAZ (Weight-for-age Z-score)≥-2 influencing factors. Results　A total of 943 children with HIV infection were enrolled in the cohort. The median HAZ at baseline and 1, 2, 5, and 10 years after treatment was -2.47, -2.14, -1.94, -1.55, -1.23, respectively, and the median WAZ was -1.85, -1.40, -1.30, -1.21, -1.09, respectively. By Cox-Stuart trend test, HAZ and WAZ showed an upward trend with the treatment time (P<0.05). The proportions of HAZ≥-2 at baseline and at 1, 2, 5, and 10 years after treatment were 38.1%, 46.5%, 51.6%, 66.8%, and 74.6%, respectively, and the proportions of WAZ≥-2 were 57.1%, 76.9%, 81.1%, 85.8% and 89.2%, respectively. According to Cox-Stuart trend test, the proportions of HAZ≥-2 and WAZ≥-2 increased with the treatment time (P<0.05). The results of multivariate generalized estimating equation analysis showed that the associated factors with HAZ≥-2 were that age at ART initiation was 3-7 years old (aOR=0.71, 95%CI: 0.53-0.94), age at ART initiation was >7 years old (aOR=0.66, 95%CI: 0.47-0.93), CD4 cell counts before ART was <200/μL (aOR=0.64, 95%CI: 0.47-0.87), WHO clinical stage before ART was Stage Ⅲ/Ⅳ (aOR=0.74, 95%CI: 0.56-0.97) and time on ART (aOR=1.01, 95%CI: 1.01-1.01); the associated factors with WAZ≥-2 were male (aOR=0.72, 95%CI: 0.53-0.97), WHO clinical stage before ART was Stage Ⅲ/Ⅳ (aOR=0.63, 95%CI: 0.45-0.86) and time on ART (aOR=1.01, 95%CI: 1.01-1.01). Conclusion　Antiretroviral therapy can effectively improve the growth and development status of children with HIV infection, but a large proportion of children still have stunted growth and development in the 10th year after treatment. It is necessary to strengthen the training of antiretroviral treatment staff and the publicity and education of parents of children infected with HIV. Improve the effect of antiviral treatment and guide children's nutrition reasonably.

The recurrence and metastasis of tumor are the main reasons for the failure in malignant tumor treatments, searching for the best target to prevent the tumor recurrence and metastasis is the focus of tumor research. Research showed that tumor stem cells are the vital factor of malignant tumor recurrence and metastasis, there is no method of target regulating the function of tumor stem cells now. Traditional Chinese Medicine have played a good role in preventing tumor recurrence and metastasis according to the previous studies, so we can suppose that tumor stem cells may be the final target of TCM in preventing tumor recurrence and metastasis. To expand the effect and study the mechanism of action we should introduce the tumor stem cells into the study of TCM in treating malignant tumor.

Objective To evaluate the role of (99)Tc(m)-MDP SPECT/CT bone fusion imaging in diagnosis and treatment strategy establishment of patients with bone metastatic malignancy.Methods Retrospective study was carried out on 66 patients (55 patients with primary malignant tumors,11 patients with primary benign bone disease) chosen from 117 patients who had undergone whole body bone scintigraphy and SPECT/CT fusion imaging examination.Comparison was carried out on diagnostic efficacy for bone metastases and changes of treatment between SPECT/CT fusion imaging and other anatomical imaging (CT and/or MR).Cases excluded are extensive bone metastases and no final diagnosis of patients.Results For diagnosis of patient with bone metastasis and bone metastasis lesion,the sensitivity of SPECT/CT fusion imaging was (90.62％,93.88％),specificity (79.41％,89.47％) and accuracy (84.84％,90.97％),while sensitivity of simple anatomical imaging was (59.38％,51.02％),specificity (94.11％,94.73％) and accuracy (77.27％,79.86％),with a significant difference (P ＜ 0.05).SPECT/CT fusion imaging changed 30.31％ (20/66) the patient's treatment plan,while 16.67％ (11/66) for simple anatomical imaging,with a significant difference (P ＜ 0.05).Conclusions SPECT/CT fusion imaging could increase the accuracy of diagnosis of bone metastases and have an important role in establishing the treatment strategy.

Objective To investigate the effects of oral calcitriol pulse therapy combined with resin adsorption in treatment of severe secondary hyperparathyroidism.Methods Thirty-two hemodialysis patinents were randomly divided into three groups:oral calcitriol pulse therapy(CP group,12 cases),oral calcitriol pulse therapy combined with resin adsorption group(CP+RA group,10 cases),and resin adsorption group(RA group,10 cases).Serum immunoreactive parathyroid hormone(iPTH),albumin,urea,creatinine,hemoglobin levels were detected before treatment and 1,2,3 months after treatment respectively.Serum calcium and phosphorus levels were also detected every half a month.Results The clearance rate of resin adsorption Was decreased significantly every time(P<0.05).Serum iPTH in CP+RA group decreased significantly 2 months after treatment.Serum iPTH3 months after treatment in CP+RA group[(598.50 ±317.45)ng/L]was less than that in CP group[(1008.67±436.85)ng/L]and RA group[(1464.60±411.27)ns/L](P<0.05).Conclusion Oral calcitriol pulse therapy combined with resin adsorption can clear iPTH safely and effectively.
