BACKGROUND: Is the inhibition of the hematopoietic stem progenitor cell (HSPC) proliferation and differentiation after human cytomegalovirus (HCMV) infection associated with abnormal expression of infected cell proliferated gene?OBJECTIVE: To observe the HOXB6-mRNA expression in the process of proliferation and differentiation of HCMV-infected HSPC into colony-forming unit granulocyte-macrophage (CFU-GM) and colony-forming unit erythroid (CFU-E).DESIGN: A controlled observation.SETTING: Laboratory for Molecular Biology, Affiliated Hospital of Luzhou Medical College, Lanzhou, Gansu Province, China.MATERIALS: All cord blood (CB) specimens were provided by the Obstetrics Department of Affiliated Hospital of Luzhon Medical College. They were collected from the umbilical vein of normal term neonates delivered spontaneously. All neonate mothers were healthy and HBS-Ag-negative. HCMV-IgM antibody revealed by routine ELUSA and HCMV-DNA checked by PCR were undetectable. Written informed consent for the laboratory measurements was obtained from each neonate mother, and the protocol was approved by the hospital's Ethics Committee. HCMV-AD169 strains were obtained from the Institute of Virology, Chinese Academy of Preventive Medicine. All-trans retinoic acid (ATRA, lot No. 20010126) was provided by Chongqing Huapont Pharm. Co., Ltd., China.METHODS: This study was performed at the Laboratory of Molecular Biology (state-level), Affiliated Hospital of Luzhou Medical College of Luzhou Medical College from April 2006 to April 2007. Cord blood mononuclear cells were separated for HSPC culture. According to different interventions, the study consisted of 4 groups. Control group: no HCMV virus solution was added and equal volume of culture medium was added instead. HCMV group: 105 PFU/mL HCMV-AD169 virus solution was added to the culture system. ATRA group: ATRA was added into the cultivation system at the final concentration of 60 μ mol/L. HCMV+ATRA group: ATRA was added into the HCMV group, and its final concentration was also 60 μ mol/L.MAIN OUTCOME MEASURES: In each group, cells were harvested on days 3,7 and 12. HOXB6 mRNA expression levels in CFU-GM and CFU-E were detected by real-time fluorescent-based quantification PCR.RESULTS: In the control group, both CFU-E and CFU-GM expressed HOXB6-mRNA. The HOXB6 mRNA expression was increased as a function of time. The HOXB6-mRNA expressed by CFU-E reached its peak level on day 12, while that expressed by CFU-GM reached its peak level on day 7. Compared to control group, the expression levels of CFU-E and CFU-GM HOXB6-mRNA genes in normal cord blood were significantly lower in the HCMV group (P＜0.05)and significantly higher in the ATRA group (P＜0.05) at each time point after HCMV infection. Furthermore, the expression levels were significantly higher in the ATRA+HCMV group than in the HCMV group at each time point(P＜0.05-0.01).CONCLUSION: HOXB6-mRNA expression is stable and lasting in the proliferation and differentiation of HSPC into CFU-GM and CFU-E. HCMV could down regulate HOXB6 gene expression, and ATRA could up regulate HOXB6 gene expression.

BACKGROUND: Clinically, in patients undergoing hematopoietic stem cell transplantation (HSCT), human cytomegalovirus (HCMV) can be associated with delayed platelet engraftment, phenotypically abnormal peripheral blood leukocytes, and graft rejection, possibly through a direct viral effect on hematopoietic progenitor cells after HCMV infection. OBJECTIVE: To investigate the inhibitory effect of ganciclovir (GCV) on proliferation of colony forming unit (CFU) granulocyte-macrophage (CFU-GM), CFU-erythroid (CFU-E), CFU T-lymphocyte (CFU-TL), CFU-multipotential (CFU-Mix) and CFU-megakaryocyte (CFU-Mk) progenitor cells of cord blood (CB) and the protective effects on them. DESIGN: Contrast observational study.SETTING: Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College.PARTICIPANTS: A total of 20 cord blood (CB) samples (with 10 mL for each sample) from fetal umbilical vein of normal term spontaneous delivery neonates were provided by the Department of Gynaecology and Obstetrics, Affiliated Hospital of Luzhou Medical College. All the patients were informed and agreed with the experiment.METHODS: The experiment was carried out in the Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College from June 2004 to December 2006. Colony forming unit-assay was applied to observe the suppression effect of HCMV-AD169 strain on CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk of CB with the presence of GCV. The techniques of polymerase chain reaction (PCR) and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk. Normal progenitor cells culture system was regarded as blank control group; normal progenitor cells culture system with inactivated HCMV fluid as inactivated (IV) control group.MAIN OUTCOME MEASURES: ① The number and maintaining duration of colonies of cultured progenitor cells were counted by using a light inverted phase contrast microscope. ② The techniques of PCR and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured progenitor cells.RESULTS: ① Number and lasting time of colonies: The numbers of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk colonies in the HCMV infection group were significantly less than those in the blank control group (P < 0.01). The maintaining duration of colonies in the HCMV infection group was significantly shorter than that in the blank control group (P < 0.01). HCMV-DNA copies of colony cells of GCV group decreased significantly by using fluorescence quantification PCR compared with HCMV group (P < 0.01), while negative in blank control and inactivated control in CFU-MK and CFU-Mix. ② CFU Growth rate: The Growth rate of colonies was 37.4%, 74.2%, 40.1%, 67.4% and 38.9% of CFU-GM, CFU-E, CFU-TL, CFU-Mix and FU-MK, respectively. ③ CFU-HCMV-AD169 DNA: Fluorescence quantification PCR showed that nucleonic acid content of progenitor cells after GCV-affected HCMV infection was decreased as compared with that after HCMV infection (P < 0.01).CONCLUSION: The differentiation and proliferation of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk are significantly inhibited after infected with CMV-AD169 strain. The growth of hematopoietic progenitor cell after HCMV-AD169 infection is promoted by GCV, which suggests that GCV has an effect of anti-HCMV in vitro.

Objective To investigate the effect of acupuncture at point Neiguan on mouse myocardial hypertrophy.Methods Thirty-sixty healthy C57BL6 mice were randomized into blank, model and treatment groups, 12 rats each. In the treatment group, an acupuncture needle was inserted into point Neiguan and retained for 15 min, once daily. After nine days of treatment, the ratios of cardiac weight/tibial length were compared between the groups. Left ventricular myocardial tissues were processed by Masson trichrome staining in every group of mice. The differences in myocardial fiber arrangement and collagen fiber distribution between the groups were observed under the ordinary optical microscope in 100 times of field of vision. Sarcomere structure, myofibril arrangement, collagen fibers and mitochondria in injured myocardial tissues were observed by transmission electron microscopy. Results Heart rate increased significantly in the model group and decreased significantly in the acupuncture group compared with the blank group. Cardiac weight and the ratios of cardiac weight/tibial length increased significantly in the model and acupuncture groups compared with the blank group (P<0.01) and decreased significantly in the acupuncture group compared with the model group (P<0.01). In the model group, myocardial tissues had compensatory hypertrophy with incontinuous status, and myocardial transverse striations had severe disorder/disruption, karyopyknosis appeared and cytoplasmic eosinophilic change became obvious in few of the rats. The results were better in the acupuncture group than in the model group. In the model group, part of myofibrils had focal fusion, interstitial collagen fibers proliferated and mitochondria had swelling and compensatory increase. The results were also better in the acupuncture group than in the model group.Conclusions Acupuncture at point Neiguan can reduce the production of collagen fibers and mitochondria, improve the arrangement of sarcomere structure and delay the progression of myocardial hypertrophy.
