Objective To establish a fast and accurate technique of identifying the pachytene spermatocytes,round spermatids and elongating and condensing spermatids during STA-PUT velocity sedimentation.Methods Using STA-PUT velocity sedimentation method to isolate the pachytene spermatocytes, round spermatids and elongating and condensing spermatids from mouse testes.To determine the cell populations` distribution,each tube of cell fraction was then partially transfered to the 96 plate well,and each well was added with acridine orange dye.Then each well was analyzed using fluorescence microscopy.Results Three types of spermatogenic cells can be identified quickly and accurately by it`s specific cytoplasm/nucleus character using the acridine orange dye staining under fluorescence detection.Conclusions A rubust method to quickly and accurately determine the pachytene spermatocytes,round spermatids and elongating and condensing spermatids during STA-PUT velocity sedimentation is successfully developed.

Objective To evaluate the effects of nasal non-Hodgkin′s lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI);and to analyze the impact factors of prognosis. Methods 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N-NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0Gy with a range of 35.2 to 75.5Gy, with added 30Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results The local control rate was 12%,69%,76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively(P=0.057).The 5-year survival rate was 9%,52%,63% and 83%,respectively(P=0.032). Multi-factor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis .Conclusions Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system.For some N-NHL patients with good financial condition, APBSCT combined with TBI is a good choice.

Objective To learn the change trend of live newborn birth condition from 1987 to 2011 in Hongjiang people′s hospi-tal .Methods Cluster sampling was adopted and altogether 2 711 singleton live newborns in 1987 ,1995 ,2005 ,2011 year were retro-spectively analyzed .Results From 1987 to 2011 ,the birth weight changes of live newborn overall showed an increasing trend .The sex ratio of birth appeared rising after 1995 ,especially apparent in parous wowen and rural areas .Incidence of macrosomia showed an increasing trend ,the post-term infant delivery rate decreased after 1995 .Low birth weight infant and premature infant birth rate trend was not obvious .Conclusion 25 years in Hongjiang people`s hospital ,the overall trend of live newborn birth outcomes is good which prompts that the quality of perinatal care in the hospital is improved .In the future ,the perinatal health care should focuse on taking effective comprehensive measures to control the growth of the birth sex ratio and the incidence of macrosomia .

As an important lipid in cell membrane and lipoprotein,sphingomyelin(SM)has widespread and considerable biological functions.It has close relation to the occurrence and development of atherosclerosis(AS),and the change of its concentration has become a seperate risk of atherosclerosis.Sphingomyelin synathase(SMS),the key enzyme in synthesis of SM,might become a new target for treatment of AS because of its expression and activity could directly influence the pathophysilogical process of AS.Here the recent reports about the structure and biological functions of SMS are summarized,and its role in AS and the possibilities of it being a potential drug target for AS therapy are reviewed.
