Neurogenesis is sustained throughout adulthood in the mammalian brain due to the proliferation and differentiation of adult neural progenitor cells found in the subventricular zone of the lateral ventricles and subgranular zone of the dentate gyrus. This review covers recent findings that elucidate different aspects of regulation of neurogenesis, including proliferation, migration and differentiation into mature neurons and functional integration into the existing neural circuits. Furthermore, this review also discusses the effects of pathological conditions on adult neurogenesis in both rodent models and human patients as well as some of the potential problems or limitations in neurogenesis research, which may shed some light on developing novel research strategies for replacement treatment of neurological disorders.

The basic nursing quality is an important dial of the general administration level and the basic personnel quality of a hospital.Many causes have led to the down trend of the basic nursing quali- ty.After a specific analysis of the causes of such a trend,important measures and solutions have been put forth,The first is to strengthen the moral education of the profession and upgrade the quality of the nursing staff.The second is to adopt the "group responsibility" administration and gradually carry out a systimatic integrated nursing so that a transformation of nursing models is put to practice,The third is to broaden the outlet of human resources so that personnel are rationally employed and the rate of job— taking raised.The last one is to heighten the initiative of the nursing staff through the rational opera- tion of the "incentive"mechanism in accordance with the law of values.

Objective To determine species, counts, and seasonal variation of airborne pollen in the center of Nanchang. Methods Pollen counts were done with Durham gravity method on the top of the building in the campus of Jiangxi Medical College, Nanchang, April 1, 2000-March 31,2002. Results There were airborne pollens in all seasons of the year in atmosphere of Nanchang, which included about 47 species. The highest airborne presence (percent of total yearly pollen counts) was for Ambrosia(35.73%); followed by Pinaceae (15.94%), Artemisia (11.94%), Gramineae (5.88%), Cupressaceae (5.64%), Cunningha-mia R.Br.(5.12%), Chenopodium-Amaranthus (5.03%) , and Humulus(2.02%). The dispelling period showed a double curve: the first peak occured in Mar. and Apr. (22.56% and 11.98% respectively). The predominant pollens were tree pollen (Pinaceae, Cupressaceae, Cunninghamia R.Br., Moraceae and Salix). The second peak occured in Aug., Sep., and Oct. (9.61%, 23.77%, 19.57% respectively). The predominant pollens were grass pollen (Ambrosia, Artemisia, Gramineae, Chenopodium-Amaranthus and Humulus). Gramineae had been scattering all seasons, but it's counts were not high in every month. Conclusion There are airborne pollens dispelling in atmosphere of Nanchang in the whole year, whose dispelling period shows a double curve (the first peak occurs in Mar. and Apr. And second peak occurs in Aug. Sep. and Oct.) and the predominant pollens are Ambrosia, Pinaceae, Artemisia, Gramineae, Cupressaceae, Cunninghamia R.Br., Chenopodium-Amaranthus and Humulus. This study provides useful scientific information for production of specific allergen and for clinical prevention, specific diagnosis, specific therapy of allergic deseases.

To examine the occurrence of neuron activation,neurodegeneraion and cell death,and the correlation among them in the hippocampus after status epilepticus.Methods CFV,Fluoro Jade B and c-Fos staining were done at multiple time points after pilocarpine induced status epilepticus.Results In the stratum granulosum of dentate gyrus,c-Fos positive neurons increased significantly at 1 h,2 h and 1 d after status epilepticus (P ＜0.01 or 0.05).However,almost no Fluoro Jade B staining cell was found in the stratum granulosum in the experiment and control groups,and no obvious difference was shown on the numbers of CFV staining cells in this area among all groups.In the hilus of dentate gyrus of different groups,there were no c-Fos positive neurons in all groups.In the hilus,the number of Fluoro Jade B staining cells significantly increased at 2 h and 1 d after the status epilepticus (P ＜0.01 ),and the number of CFV staining neurons dramatically decreased 1 d after the status epilepticus ( P ＜ 0.01 ) compared with the control.In the stratum pyramidale of CA1,the numbers of c-Fos positive neurons at 30 mim,1 h,2 h and 1 d,and Fluoro Jade B staining cells at 2 h and 1 d after the status epilepticus significantly increased (P ＜ 0.01 or 0.05 ),while no obvious difference in the number of CFV staining cells in the stratum pyramidale of CA1 among different groups was shown.Conclusion There is no direct correlation among cell activation,neuron degeneration and cell death in the hippocampus of mice after pilocarpine induced status epilepticus.

Objective To explore the changes of placental growth factor (PLGF) in patients with acute coronary syndrome (ACS).Methods One hundred and twelve patients were divided into four groups according to clinical data and coronary angiography:non-coronary artery disease (non-CAD) group (27 cases),stable angina (SA) group (28 cases ),unstable angina (UA) group (29 cases) and acute myocardial infarction (AMI) group (28 cases).Fifty-seven patients with ACS were divided into single lesion group (19 cases),twice lesion group ( 16 cases) and triple lesion group (22 cases) by coronary angiography,and 0-7 scores group (23 cases),8-15 scores group (27 cases) and 16-32 scores group (7 cases) by Jenkins scores.The serum PLGF levels of all the cases were determined on admission.The serum PLGF levels of 40 cases receiving percutaneous coronary intervention (PCI) were determined at 30 min before operation,the first and second day after operation.Results The serum PLGF levels of AMI group and UA group were (38.33 ±10.14) ng/L and (37.44 ± 13.32) ng/L respectively,which were significant higher than that of SA group [(20.90 ± 3.88) ng/L] and non-CAD group [(20.34 ±4.53) ng/L](P＜ 0.01),and there was no significant difference between AMI group and UA group,SA group and non-CAD group (P ＞0.05).There was no significant difference in the serum PLGF level among triple lesion group,twice lesion group and single lesion group (P ＞ 0.05 ).There was no significant difference in the serum PLGF level among 0-7 scores group,8-15scores group and 16-32 scores group (P ＞ 0.05).The serum PLGF level of patients receiving PCI on the first day after operation [ (32.03 ± 7.41 ) ng/L] was significantly higher than that before operation [ (23.86 ± 6.91 ) ng/L](P＜ 0.05 ),and on the second day after operation the serum PLGF level [ (29.37 ± 6.99) ng/L] was less than that on the first day after operation,showing a fall tendency(P＞ 0.05).Pearson correlation analysis showed that the serum PLGF levels in patients with ACS were not related with cardiac troponin T and creatine kinase isozyme-MB (r =-0.158,P=0.421;r =0.302,P=0.118).Conclusion The serum PLGF level of ACS patients is an inflammatory marker reflecting coronary atherosclerotic plaque destabilizing or plaque ruptured,and may also play an important role in early diagnosis of the borderline case of ACS.

Objective To investigate the mechanism of treatment of lung cancer with Bacillus Calmette-Guerin Polysaccharides nucleic acid (BCG-PSN) combined with Cyclophosphamide(Cy). Methods 130 mice were divided into three groups (A,B and C groups). Gruop A was further divided into four subgroups . Subgroup A-1 was given normal saline orally 0.25mg/10g?d -1 ; Subgroup A-2 was given levomisole PO. 0.25mg/10g?d -1 ; Subgroup A-3 was given BCG-PSN PO.0.325mg/10g?d -1 and subgroup A-4 was given BCG-PSN by intra-abdominal injection 0.25mg/10g?d -1 . Group B was given identical drugs with group A, after fifth day given 20% sheep red blood cell 0.2ml by intra-abdominal injection for five days . Gruop C divided into five subgroups;Subgroup C1-4 were given same drugs with group A,then given 0.4% Cy by subcutaneous injection 0.25mg/10g?d -1 from fifth day to tenth day.Subgroup C-5 was normal contral group, was given normal saline 0.25mg/10g?d -1 PO and subcutaneous injection 0.25mg/10g?d -1 .Results Oral administration alone or intra-abdominal injection in subgroup A-4 obviously enhanced the phagocytosis of macrophages.The subcutaneous injection of Cy could obviously decrease anti-tumour immunity, including activity of interleukin-2 (IL-2),natural killer(NK) cell, lyphocyte trasformation, and macrophages phagocytosis. BCG-PSN could increase and rehabilitate above anti-tumour immunological function. Conclusions Combinative treatment of BCG-PSN with Cy could remarkable enhance the immunocompetence.This experiment may provide a theoretical evidence for BCG-PSN combined with chemotheapeutic agents applied to treat the lung cancer.
