Objective To explore the change and the spectra of opportunistic infections in AIDS patients after antiretroviral treatment in He′nan province.Methods Inpatients of post treatment with disease in accordance with the criteria were selected from the Sixth People′s Hospital of Zhengzhou.A retrospective study was carried out, including the content such as gender,age,infection route,treatment time,the date of complication,and CD4+T lympho-cyte counts when the patient with complications.Disease were divided into four group:opportunistic infections,adverse drug reactions,tumor,cardio-cerebrovascular disease and diabetes mellitus.Statistic case number and incidence of every kinds of the disease in the different stages of HAART.Results (1)1 001 cases of patients were involved in the result analysis.People of 41-60 years old,the peasants and peasant workers,accounted for 57.4%and 78.9%.The infection route was mainly through blood transmission and blood collection, accounting for 83.45%.Most of the patients come from Zhumadian, Xuchang, Zhoukou, Nanyang, which were high -incidence area in He′nan.( 2 ) In 1 001 patients of post treatment, the rate of opportunistic infections was 58.4%, while adverse drug reactions was 30.5%.Bacterial pneumonia,extrapulmonary tuberculosis,oral cavity fungal infection and tuberculosis were common in opportunistic infections of patients of post treatment.The main adverse reactions were allergic dermatitis,liver injury and myelosuppression.The liver cancer case was the highest ( 8/29 ) .( 3 ) 1 001 cases were divided into 6 groups according to different count of treatment time,during 3 months of treatment,the incidence rate of opportunistic infec-tions and adverse drug reactions was the highest,accounted for 75.2% and 41.6%.After 5 years of treatment,the incidence rate of cardio-cerebrovascular disease and diabetes mellitus was 6.39%.With the prolonging of HAART time,incidence of opportunistic infections and adverse drug reactions remarkably reduced,but the occurence rate car-dio-cerebrovascular disease and diabetes mellitus increased.Conclusion In AIDS patients after HAART in He′nan at present,opportunistic infections and adverse drug reactions are main diseases and used to occur during three months after HAART.Attention will be focused on tumor, cardio -cerebrovascular disease and diabetes mellitus in AIDS patients of long-term survival.

Objective To study the inhibitory effect of arsenic trioxide(AS2O3)on the tumor growth of breast cancer line MDA-MB-435s implanted subcutaneously in nude mice and its mechanism.Methods BALB/C-nu/nu nude mice were subcutaneously injected with MDA-MB-435s breast cancer cells that are ER-positive,and treated with intraperitoneal injection of AS2O3 and DDP in different concentrations.The implanted tumor was weighed,and tumor inhibition rates were calculated.The expression of PTEN and Caspase-7 induced by AS2 03 were examined by immunohistochemical method.Results The growth of implanted tumor was markedly inhibited with DDP,low dose and high dose AS2O3,and the inhibitory rates were 48.68%,32.80%,66.67%respectively.The immunohisto chemical staining showed that the number of PTEN and Caspase-7 protein increased markedly(P＜0.05).Conclu sions AS2O3 inhibits the growth of human breast cancer cell implanted tumor.The molecular mechanism of AS2O3 on induction of apoptosis of breast cancer cells may be throush increasing the expression of PrrEN and Caspase-7(P ＜0.05).

Objective:To analyze the clinical characteristics of primary acute myeloid leukemia (AML) (non-M3 type) in children suffering from different levels of platelet count(PLT).Methods:In the Tumor Hospital of Zhengzhou University from January 2014 to December 2018, laboratory and clinical data of 247 de novo primary AML pediatric patients were retrospectively reviewed.According to the PLT before treatment, patients were divided into very low platelet group (VLG), low platelet group (LG) and non-lowing platelet group (NLG), with<50×10 9/L, ≥50×10 9/L but <125×10 9/L and ≥125×10 9/L as the boundaries.All patients were followed up until June 30, 2019.Meanwhile, the follow-up data was obtained by consulting medical records or by telephone.SPSS 17.0 software was applied for data analysis. Results:In general clinical features, a different group of hemoglobin (Hb) content, fusion gene AML- ETO and clinical risk stratification were statistically significant in different PLT groups ( χ2=11.270, 12.115 and 12.848, respectively, all P<0.05). However, the differences of other indicators in different groups of PLT were not statistically significant (all P>0.05). There were no statistically significant differences in terms of 3-year disease-free survival(DFS) rate (59.3%, 36.3%, 50.4%) among the 3 groups (all P>0.05). The median total survival(OS)time(40.5 months)and 3-year OS rate(41.0%) of NLG patients were significantly higher than those of VLG(23.1 months, 30.1%)and LG(14.1 months, 18.2%)patients, with statistically significant differences( χ2=7.798 and 6.553, respectively, all P<0.05). The univariate analysis of gender, white blood cell(WBC), Hb, PLT, lactic dehydrogenase(LDH), FLT3-ITD, NPM1, DNMT3A, CEPBA, C-KIT, AML-ETO, molecular genetic prognosis, complete remission(CR), and hemopoietic stem cell transplantation(HSCT) displayed that DNMT3A mutation was an adverse factor that affects patients′ OS ( χ2 =5.834, P<0.05), and the positive factors that influences OS were non-reducing PLT before treatment, and obtaining CR and subsequent HSCT ( χ2=7.798, 79.168, and 31.337, respectively, all P<0.05). Multi-factor analysis revealed that the independent protective factors that affect patients′ OS were the non-reducing PLT before treatment, and obtaining CR and subsequent HSCT( Wald=42.760, 15.918, and 10.183, respectively, all P<0.05). Conclusions:Before treatment, non-reducing PLT is a protective factor for primary childhood AML patients, and the prognosis is satisfying.

BACKGROUND:With the increase of aging degree, chronic wounds are increasing. There is few method to cure chronic wounds at present, and vacuum sealing drainage has been applied to the clinic.
OBJECTIVE:To investigate the effect of vacuum sealing drainage on the expression of nerve growth factor and the change of microvascular number in the human chronic wounds, and to study the mechanism of accelerating chronic wound healing.
METHODS:Ten patients with chronic wounds were included in this study, including one case of soft tissue defect of chest, one case of osteomyelitis with bone exposure, one case of large area skin defect after amputation stump, two cases of wound infection after skin avulsion injury, two cases of shinbone osteomyelitis, and three cases of postoperative wound infection. The skin around the wounds and granulation tissue within the wounds were col ected before vacuum sealing drainage treatment and at 7, 14 days after vacuum sealing drainage treatment. The nerve growth factor expressions and the microvascular number in the wounds were measured by the immunohistochemical technology. The wound healing was also observed.
RESULTS AND CONCLUSION:The nerve growth factor expressions in fibroblasts and vascular endothelial cel s at 7 and 14 days after vacuum sealing drainage treatment were significantly higher than that before treatment (P<0.001). The microvascular number was also increased after vacuum sealing drainage treatment compared with pre-treatment (P<0.05-0.01). The vacuum sealing drainage treatment reduced necrotic tissue and purulent secretion within the wounds, as wel as swel ing around the wounds. Simultaneously, granulation tissue gradual y became fine granules, bright red, and bleeding easily, thus it is suitable for promoting wound healing.

Objective To evaluate the efficacy and tolerance of antiretroviral therapy (ART)regimen containing lopinavir/ritonavir (LPV/r) as a second-line regimen.Methods Data of acquired immunodeficiency syndrome (AIDS) patients who have received the first-line therapy for over a year and changed to the second-line antiviral therapy regimen containing LPV/r for more than one year were collected retrospectively from the database of free antiviral therapy in Henan Province from January 1,2009 to December 31,2013.Based on the viral load inhibition status after the alteration of the regimen,the patients were assigned to virology failure with first-line therapy group,and successful viral inhibition but poor immunological reconstruction with first-line therapy group.The variation trend of CD4+ T lymphocyte counts of the two groups in 6,12,24 months after changed to the second-line regimen of LPV/r,the virology inhibition rates between 6 and 12 months,12 and 24 months,and occurrence of adverse events were analyzed.Quantitative data were analyzed by rank sum test,and qualitative data were analyzed by chi-square test.Results A total of 4 113 patients were divided into two groups,including the first-line therapy failure group (n=3 802) and poor immunological reconstruction group (n=311).At 6,12 and 24 months after the alteration of the regimen,the CD4+ T lymphocyte counts increased gradually (all P＜0.01).Between 6 and 12 months after the first-line therapy failure group changed to the secondline regimen,viral inhibition rate was 61.65％(1 408/2 284),while that 12 and 24 months was 68.91％(2 044/2 966).The incidences of adverse reaction of the two groups were 21.88％ (832/3 802) and 22.19％(69/311),respectively,which were not significantly different (x2 =0.015,P=0.901).Condusion The ART regimen containing LPV/r still has good viral inhibition effect and immunological reconstruction effect for AIDS patients who failed the initial therapy with poor immunological reconstruction.

AIM:To observe the Toll-like receptor 9 (TLR9) activation in microglia BV-2 cells after oxygen-glucose deprivation and reoxygenation ( OGDR) , and its effects on neuronal apoptosis.METHODS:The BV-2 cell super-natants were collected after the corresponding treatment and added to mouse primary cortical neurons after OGDR for 4 h, followed by normal culture for 24 h.The cells were divided into normal BV-2 group, NC-siRNA group, TLR9-siRNA group, OGDR group, OGDR+NC-siRNA group, OGDR+TLR9-siRNA group and control group (without adding BV-2 cell supernatant) .The changes of the neuronal morphology were observed under an inverted phase-contrast microscope, and the neuronal apoptosis was detected by TUNEL.The protein expression of cleaved caspase-3 was detected by Western blot-ting.RESULTS:After OGDR, the axon turned thin, twisted and broken, and neuronal swelling, decrease in refraction and vacuolar degeneration were observed.The green-stained apoptotic bodies in the neurons in all groups were positive. Compared with control group, the caspase-3 protein levels in other groups were increased.Compared with the normal BV-2 group, the caspase-3 protein in OGDR group and TLR9-siRNA group was increased.Compared with OGDR+TLR9-siRNA group, the caspase-3 protein in TLR9-siRNA group and OGDR group was decreased.CONCLUSION: After OGDR, TLR9 activation in BV-2 cells induces neuronal apoptosis with the increase in caspase-3 protein level.Inhibition of TLR9 expression reduces neuronal damage.
