Objective To explore the effect of meridian push press cooperating with medicinal food therapy on the quality of life in patients with angina disease. Methods Random parallel controlled clinical research was used in this research. 122 patients with angina disease were divided into four groups: 31 in the meridian push press group, 30 in the medicinal food therapy group. 31 in the meridian push press cooperating with medicinal food therapy group, and 30 in the control group. The control group was treated with the conventional treatment and nursing, the other three groups were treated with not only the conventional treatment and nursing, but also the meridian push press treatment, medicinal food therapy and meridian push press cooperating with medicinal food therapy. There were 3 courses of treatment and each course of the treatment was lasted in 2 weeks. The quality of life in patients with angina disease was evaluated by the Seattle Angina Questionnaire (SAQ), the MOS item short from health survey (SF-36) and the nitroglycerin consumption.Results Degree of physical activity limitation scores in Seattle Angina Questionnaire for four groups were different[(65.77 ±8.55), (66. 17 ±8.31), (74.68 ±4.28) and (62.63 ±8.45)], with a statistical significance( F = 14. 15 ,P ＜ 0. 01 ). Four groups of patients after 3 courses of treatment in the Seattle Angina Questionnaire, the MOS item short from health survey and the nitroglycerin consumption were significantly different by analysis of variance (F=8.55,7.53,8.46;P＜0. 01). Conclusions The meridian push press cooperating with medicinal food therapy can improve the curative effect and quality of life in patients with angina disease. It will provide the basis for TCM nursing and the research results can be promote to the community nursing to play a role of secondary prevention.

The patient,a 11-year-old boy,presented with a 4-year history of erythema and vesicles on the face and arms as well as a 4-month history of tumor and ulcer on the extremities,accompanied by progressive fatigue and intermittent fever.The patient had a body temperature of 37.7℃.No lymph node involvement was observed.Cutaneous examination revealed minimally indurated pink-red patches on the face and nose and dusky red firm nodules and tumors of varying sizes on the extremities.The nodules ranged from 2.0 cm to 18 cm in diameter,some had necrosis and black crusts on the surface.Ulcers were observed in some of the larger nodules;many of the ulcers extended into the muscle layer.White purulent discharge was seen on the surface of many of the nodules.The lesions were sharply demarcated,firm,tender, and surrounded by small satelite nodules.Histologically,there were large quantities of irregularly shaped, middle-sized tumor cells with clear cytoplasm,large twisted nuclei and prominent chromatin,infiltrating from the epidermis to subcutaneous tissue.The tumor cells infiltrating the follicles and eccrine sweat glands were either distributed perivascularly in a nest shape,or dispersed.There were broken nuclei and reactive histio- cytic infiltration in the dermis and subcutaneous tissue.Immunohistologically,the tumor cells were positive for cytoplasmic CD3 around the nuclei,for CD56,CD45RO and T cell intracellular antigen-l,and partly for CD30,CD8 and Ki67.Epstein-Barr virus-encoded nuclear RNA was positive with in situ hybridization. TCR?-2 gene rearrangement was positive in these tumor cells.A diagnosis of hydroa vacciniforme-like primary cutaneous NK/T-cell lymphoma was made.Therefore,this is a case report of hydroa vaccini- forme-like primary cutaneous NK/T-cell lymphoma with primary involvement in the skin;the condition was slowly progressive over 51 months.

To explore the growth and development and analyze the quality of the parthenocarpy fruit induced by exogenous hormones of Siraitia grosvenorii. the horizontal and vertical diameter, volume of the fruit were respectively measured by morphological and the content of endogenous hormones were determined by ELISA. The size and seed and content of mogrosides of mature fruit were determined. The results showed that the fruit of parthenocarpy was seedless and its growth and development is similar to the diploid fruit by hand pollination and triploid fruit by hand pollination or hormones. But the absolute value of horizontal and vertical diameter, volume of parthenocarpy fruit was less than those of fruit by hand pollination, while triploid was opposite. The content of IAA, ABA and ratio of ABA/GA was obviously wavy. At 0-30 d the content of IAA and ABA of parthenocarpy fruit first reduced then increased, content of IAA and GA parthenocarpy fruit was higher than that of fruit by hand pollination. Mogrosides of parthenocarpy fruit was close to pollination fruit. Hormones can induce S. grosvenorii parthenocarpy to get seedless fruit and the fruit shape and size and quality is close to normal diploid fruit by hand pollination and better than triploid fruit by hormone or hand pollination.

The long-period CT perfusion imaging leads to an excess amount of radiation dose to the patient. However, the radiation dose could be significantly reduced if a previous normal-dose image is acquired before a set of low-dose scans of perfusion, and a filtering processing is performed on the differences between the current low-dose images and the previous normal-dose image, then the results are added to the previous image. But the selection of plenty of parameters makes the algorithm complicated. This paper proposes an innovative approach performed in sinogram domain instead of in image domain. First a normal-dose image and a set of low-dose projection data are acquired before the perfusion. Second the perfusion information is commendably reconstructed with sparsity constraints of the differences between current low-dose perfusion sinograms and previous low-dose sinogram. Finally, the reconstructed perfusion information is added to the previous normal-dose image. The proposed method was validated by simulated experiments with a set of brain CT perfusion images, which showed that the new method provided more accurate perfusion information; the time-attenuation curve was more close to that for normal-dose scan and the mean transit time more repeatable.

Methods To the residents lived in the city of Nanning in Cuangxi Province, a questionnaire survey was used to acquaint relevant information. The AFB1-albumin adducts (AAA) levels were screened by enzyme-linked immunosorbent assay and the liver function detected using a Bekman LX20 Chemistry Analyzer and diagnostic agents from Randox, UK. Results AAA level was significantly higher (P<0.05) in the people with lowincome, having habits of smoking, drinking, eating bulk rice, and eating rice that had been saved for a time of more than 30 days, and keeping regularly dining out. Conclusions The level of income and the lifestyle are related with Aflatoxin Bl exposure. The risk factors about Aflatoxin Bl exposure include consumption of bulk rice, regularly dining out, and drinking.

OBJECTIVETo investigate the mechanism and the suppression effect of human cytomegalovirus (HCMV) on hematopoietic system.

METHODSSemi-solid culture system was used to observe the effect of HCMV AD169 strain on colony forming unit granulocyte/macrophage (CFU-GM), CFU-erythroid (CFU-E), CFU-multipotent (CFU-Mix) and CFU-megakaryocyte (CFU-MK) growth. The techniques of in situ polymerase chain reaction (IS-PCR) and polymerase chain reaction (PCR) were used to demonstrate the existence of HCMV DNA in the colony cells of cultured CFU-GM, CFU-Mix, CFU-MK and CFU-E, respectively. The immediate early antigen (IEA) mRNA in CFU-MK and late antigen (LA) mRNA in CFU-E were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). HCMV early protein P52 was detected with immunohistochemical technique.

RESULTSHCMV AD169 suppressed the differentiation and proliferation of CFU-GM, CFU-E, CFU-Mix and CFU-MK in vitro significantly (P < 0.05). The suppression was dose-dependent. HCMV DNA was successfully detected in CFU-GM, CFU-Mix, CFU-MK colony cells from viral infection groups by IS-PCR, and was detected in CFU-E by PCR, while it was negative in blank control or mock control groups. CFU-MK colony cells expressed HCMV IEA mRNA with the size of 340 bp in virus infection groups of 10(3) plague forming unit (PFU), 10(4) PFU and 10(5) PFU, respectively. The HCMV LA mRNA was detected by RT-PCR and was 263 bp long in positive control group of HCMV-infected human embryonic fibroblasts. The expression of HCMV LA mRNA in CFU-E was negative. The early protein P52 of HCMV in 10(4) PFU group was also identified by immunohistochemical staining.

CONCLUSIONHCMV AD169 strains inhibited the differentiation and proliferation of CFU-GM, CFU-E, CFU-Mix and CFU-MK by the infection of the hematopoietic progenitors. HCMV might cause the suppression of hematopoiesis by direct infection, which is thought to be one of the reasons of HCMV infection associated with thrombocytopenia, neutropenia and anemia.

The study was purposed to investigate the proliferation and the suppression effect of human cytomegalovirus (hCMV) on human promyelocyte cell line HL-60, and to study whether hCMV can induce apoptosis of HL-60 via direct infection in vitro and its mechanism. Promyelocyte cell line HL-60 and hCMV AD169 strain were co-cultured. PCR was used to detect the direct infection of HL-60 cells by hCMV IEA expression. The apoptosis cells were analyzed by morphologic observation, DNA ladder formation, flow cytometry with Annexin V/PI stain. The results indicated that hCMV AD169 suppressed the differentiation and proliferation of HL-60 cells in vitro significantly (P < 0.05). The suppression was dose-dependent. hCMV DNA was successfully detected in HL-60 cells of viral infection groups by PCR. The apoptotic cells were confirmed by morphologic observation and DNA ladder formation. The results of flow cytometry showed that the percentage of apoptotic cells increased along with the increase of hCMV titer and the time after infection. It is concluded that the promyelocyte can be infected directly by hCMV AD169 strain. hCMV AD169 strain inhibited the differentiation and proliferation of promyelocyte. The apoptosis of HL-60 cells can be induced by hCMV infection. With the increase of viral infectious titer and the time after infection, the percentage of apoptotic cells also increase and produce in dose-dependent and time- dependent manner. Induced apoptosis may be one of the mechanisms of granulocytopenia induced by hCMV infection.
