OBJECTIVEChina began providing antiretroviral therapy to people living with HIV/AIDS (PLWHA) in 2003. This study was to investigate the living conditions, including quality of life and happiness, and need for palliative care of end-of-life PLWHA in rural Henan.

METHODSOne hundred end-of-life AIDS patients were selected from Weishi, Zhenping and Tanghe counties in Henan, using convenience sampling. The World Health Organization Quality of Life for HIV (WHOQOL-HIV) BREF Chinese Version was used to measure the quality of life and the Memorial University of Newfoundland Scale of Happiness (MUNSH) was employed to measure subjective welfare. Qualitative interviews and focus group discussions were undertaken to learn about the palliative care provided and the specific needs of the end-of-life patients.

RESULTSPatients' overall quality of life was moderate (12.62±1.97). Highest scores were in the spirituality/religion/personal beliefs, higher than the average scores in the Chinese population (P<0.01), while psychological (13.58±2.06) and environment (12.50±3.28) domain scores were similar to the latter (P>0.05). Both independence (12.15±2.15) and physiological (14.04±3.16) domain scores were lower than the average of the people living with HIV/AIDS in other studies (P<0.01); however, all were in the moderate range. The average MUNSH score was 21.00±6.20, which was also moderate. The in-depth interviews indicated that the Henan Provincial Government's policy of treatment and care had a beneficial impact on end-of-life AIDS patients, although the care components could be improved.

CONCLUSIONSLiving conditions of the end-of-life AIDS patients were moderate, and the HIV/AIDS palliative care model used was beneficial to them. Care could be improved by assisting the family unit as a whole.

OBJECTIVETo investigate the effect of EBV immediate-early protein Zta on cell cycle of Daudi cells and the involved mechanisms.

METHODSThe expression vector encoding Zta was constructed and electroporated into Daudi cells. Flow cytometric analysis was used to detect the cell cycle, Western blot to the protein levels of p21, Rb and E2F-1.

RESULTSThe vector was constructed successfully, the expression of Zta protein inhibited the proliferation of Daudi cells and promoted cell cycle from G(0)/G(1) phase \[(30.0 ± 3.4)%\] to S phase \[(47.7 ± 1.1)%\]. Meanwhile, Rb expression was significantly downregulated, E2F-1 and p21 expression upregulated by Zta.

CONCLUSIONZta could promote G(0)/G(1) phase to S phase transition in Daudi cells, which might be associated with the reduced expression of Rb and increased expression of E2F-1 and p21 protein.

This study was aimed to investigate the immunological effect of modified dendritic cells (DC) which inducing cytotoxic T cells (CTL) against lymphoma cells. The DC were isolated from the lymph node and peripheral blood of patients with diffuse large B cell lymphoma (DLBCL). DC were transfected with recombinant adenovirus vector carrying human p53 gene (rAd-p53-DC). The expression of p53 gene was detected by flow cytometry. Western-blot was used to detect the expression of P53. ELISA was used to detect IL-12 level in supernatant. The mixed lymphocyte reaction (MLR) was used to detect the proliferative ability of auto-lymphocyte stimulated by DC. The lactate dehydrogenase (LDH) release test was used to determine the cytotoxicity of CTL. The results indicates that the expressions of DC surface molecule (except for CD1a) such as CD83, CD80, CD86 and HLA-DR were significantly higher in experiment group than that in control group and blank control group. The secretion of IL-12 in supernatant was higher in experiment group than that in control group. The autologous T lymphocyte proliferation and cytotoxic activity against the same kind of DLBL-cells increased in experiment group as compared with control group and blank control group (P < 0.05). The ability to stimulate T lymphocyte proliferation increased with the rising of the ratio of DC and T lymphocyte. However, there was statistically significant difference between rAd-p53-DC derived from Lymph node and peripheral blood (P < 0.05). It is concluded that rAd-p53-transfected DC can induce CTL response in vitro against lymphoma cells.

OBJECTIVETo observe the intervention of liuwei dihuang pill (LDP) on therapeutic effectiveness and adverse reaction of hormonotherapy in treating nephrotic syndrome.

METHODSPatients allocated in two groups were medicated with initial dose of prednisone 1 mg/kg once a day at 8 am in the morning. After being medicated for 8 to 12 weeks, the dose of prednisone was decreased by 5.0 mg every 2 weeks till 0.5 mg/kg per day. Then the medication was changed to that two days' dosage orally take once a day with the daily dose reduced by 5.0 mg/kg every 2 to 3 weeks, and maintained at 0.4 mg/kg once every two days. At same time, necessary symptomatic treatment was given. To the treated group oral administration of LDP 8 capsules was given additionally, 3 times per day until prednisone decreased to maintenance dose.

RESULTSTherapeutic effect in the treated group was significant better than that in the control group (P < 0.05). Urinary protein, plasma albumin, triglyceride (TG) and total cholesterol (TC) in both groups were obviously improved (P < 0.05 or P < 0.01). However, as compared with the control group, the improvement was better, and the recurrent rate was lower (P < 0.05) in the treated group. Scores of Yin-deficiency caused excessive Fire syndrome and incidence rate of adverse reaction in the treated group were lower than those in the control group (P < 0.05 or P < 0.01).

CONCLUSIONLDP can markedly improve the therapeutic effectiveness and counteract the adverse reaction of hormonotherapy in treating nephrotic syndrome, and reduce the recurrence of the disease.

AIMClinical studies stated that low molecular weight compounds (< 1.0 kd) extracted from the new born calf liver could effectively inhibit the proliferation of tumor cells. In this report, we observed inhibition effects and their regulative mechanisms of taurine, ornithine, carnosine on the proliferation of HL-60 cells.

METHODSThree active ingredients, i.e., taurine, ornithine and carnosine were separated by ion-exchange chromatographic column and identified from the low molecular weight filtrate of new born calf liver. MTT assay was used to test the survival rate of HL-60 cells and normal lymphocytes treated by the three ingredients. The various effects of the three compounds on HL-60 cells were respectively evaluated by agarose gel electrophoresis, ESR and immunohistochemical methods.

RESULTSThese compounds effectively inhibited the proliferation of HL-60 cells and induced apoptosis which was determined by apoptotic changes in morphology and nuclear DNA degradation. Whereas no inhibition effects on normal lymphocytes were observed. In addition, the results of ESR showed that the activity of oxygen radical within HL-60 cells treated with there compounds decreased to trace level. Furthermore, in the immunohistochemical experiments, we found that the level of p45/skp2 in HL-60 cells decreased while the level of p27/kip increased.

CONCLUSIONThe taurine, ornithine and carnosine compounds can selectively suppress tumor cells proliferation by regulating the level of cell cycle proteins.

Histone lysine methyltransferase EZH2 has been reported to be frequently overexpressed in hepatocellular carcinoma (HCC) tissues and associated with hepatocarcinogenesis. However, the exact mechanism of EZH2 up-regulation in HCC has not been determined. In this study, we used murine hepatocyte AML12 cells to investigate the role of hepatitis B virus X protein (HBx) in regulating the expression of mEZH2. Western blot analysis demonstrated that the expression level of mEZH2 protein in AML12 cells was up-regulated by HBx in a dose-dependent manner. To further investigate the mechanism of mEZH2 overexpression, the 2500 bp regulatory sequence upstream from the first exon of the mEZH2 gene was amplified from AML12 genomic DNA and constructed into a luciferase reporter plasmid. The luciferase activity of the mEZH2 promoter significantly increased in AML12 cells co-transfected with HBx plasmid, and deleting the -486/-214 promoter region decreased HBx-induced mEZH2 promoter activation by nearly 50%. The -486/-214 region was then analyzed in the TRANSFAC 6.0 database and a typical E2F1-binding site was found. Mutation of this E2F1-binding site or knockdown of E2F1 expression by RNAi led to a dramatic decrease in HBx-induced activation of the mEZH2 promoter and mEZH2 overexpression in AML12 cells. These results provide evidence that HBx up-regulates mEZH2 expression by transactivating the mEZH2 promoter through E2F1 transcription factor, thereby providing new epigenetic evidence for the carcinogenic effect of HBx.

Objective To investigate the prognostic value of different stages of TNM in patients with appendiceal neuroendocrine tumors (NETs). Methods The clinical data of 40 cases of NETs were analyzed, and follow-up data were staged by the ENETS and AJCC TNM staging system. Kaplan-Miere survival curves were used to compare survival differences in patients with different stages of TNM. Results Of the 40 patients, no one was diagnosed as appendiceal NETs before surgery. Twenty-one patients were diagnosed as acute appendicitis, 16 were diagnosed as chronic appendicitis and 3 were suspected as appendiceal tumors due to thickening of the lumen before surgery. No clinical manifestations were found in 40 patients before surgery including diarrhea, abdominal pain, facial flushing, asthma-like seizures and other carcinoid syndrome performance. All patients underwent appendectomy, and appendix NETs were diagnosed by pathology after surgery. In 40 appendical NETs patients, 15 cases were classified as stageⅠ(37.5%), 10 cases were classified as stageⅡA (25%), 2 cases were classified as stageⅢA (5%), 13 cases were classified at stageⅢB (32.5%), and no patients were classified as stageⅣ. The median survival times (months) were 27, 22, 21 and 18 for patients with different stages, and there were no significant differences in survival times between four stages (χ2=0.8988,P>0.05). Conclusion The clinical features of appendical NETs are nonspecific. The diagnosis of appendical NETs is based on pathological examination and immunohistochemistry. There are no correlation between different TNM stages and prognosis of patients.
