Objective To study the dynamic changes and clinical significance of pulmonary function (PF) in segmental mycoplasma pneumonia (SMPP) children and make the dynamic analysis of X-ray features.Methods Eighty-three SMPP children treated from June 2013 to December 2014 in Jinshan Institute of the Sixth People's Hospital of Shanghai were selected and the PF changes at acute phase, recovery phase and rehabilitative period was monitored and all the patients received the imageological diagnosis.The Pulmonary function includes forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), forced expiratory volume ratio(FEV1/FVC), peak expiratory flow(PEF), and maximum expiratory flow (FEF25-75).Pulmonary function and imageological diagnosis of two groups was compared.Results Compare the acute phase and recovery phase and rehabilitative period of 83 SMPP Children, at acute phase, FVC ((1.58±0.49), (1.76 ±0.62),(2.08±0.84) L),FEV1((1.27±0.46),(1.58±0.53),(1.83±0.66) L),FEV1/FVC((79.64±6.61)％,(85.25±7.38)％,(87.24±8.61)％),PEF((2.61±0.84),(3.15±0.92),(3.52±1.06) L/s), FEF25 ((2.29±0.83), (2.86± 0.95), (3.26± 0.98) L/s), FEF50 ((1.51 ± 0.52), (2.12 ± 0.64), (2.26±0.63) L/s),FEF75((0.58±0.42),(0.76±0.46),(1.02±0.42) L/s) and FEF25-75 ((0.61±0.33),(0.87±0.36), (1.01 ±0.41) L/s) of two groups were reduced, especially FEF25, FEF50, FEF75 and FEF25-75.At recovery phase and rehabilitative period ,the indicators were significantly better than those of acute phase (P＜ 0.05);for SMPP children at acute phase, FVC ((1.51 ± 0.44), (1.31 ± 0.36) L) and FEV 1 ((1.46±0.56), (1.21±0.48) L) in the lesions of multiple parts was significantly lower than that of lesions of single part(P＜0.05).At acute phase, X-ray majorly showed the unilateral lesion with increased density and blurring edges in lung lobe or segment.After 14 d, the condition was obvious improved;a few cases still had the blurring textures and thickening conditions after 2 weeks.Conclusion For SMPP children at acute phase,the major and micro airway function is damaged in different extent.It is majorly expressed as restrictive ventilation dysfunction,especially micro airway function.At recovery phase, PF is obviously improved.The damage of major airway function in the multiple parts of lung lobe is more serious than that of lesions in the single part.

BACKGROUND: Neural axon regeneration is one of the difficulties that must be overcome in treatment of injury of central nerve system. Significant therapeutic effects have been obtained in transplantation of neural stem cells (NSCs), embryonic stem cells (ESCs) and Schwann cells. But the bottleneck situation of insufficiency of cell provider has limited the development on it.OBJECTIVE: To observe directional-differentiation of retinoic-acid induced ESCs so as to find optimal condition for neuronal differentiation.DESIGN: Non-randomized controlled experiment was designed.SETTING: Teaching-Research Room of Histology and Embryology, Department of Basic Medicines. Third Military Medical University of Chinese PLAMATERIALS: The experiment was performed in Staff Room of Histology and Embryology, Third Military Medical University of Chinese PLA from January to May 2000. Eighteen Kunming mice in disoestrus were employed, of which. 12 mice were female and 6 mice male. They were placed in same cage at ratio of 2:1 for mating. The date of pregnancy was recorded. MESPU35 ESC line was prepared.METHODS: Removed head. internal organs and four limbs, feeder-layer Feeder-layer adherent culture was used to proliferate MESPU35 ESCs.Classic 4-/4+ method [The embryoid body (EB) grew naturally for 4 days,without retinoic acid added. In the coming 4 days, retinoic acid was added to induce neural EB of high proportion] was applied to induce the directional differentiation of the nerve. EB was cultured with serum of different concentrations. Phase contrast microscope was used to observe nerve-like EB in serum of different concentrations and to count numbers. ②Immunocytochemical technique was used to observe cellular morphological charac ters at various differentiating phase spots (5th. 9th, 14th days) and with retinoic acid at various concentrations. Flow cytometer (FCM) was used to count the proportion of differentiated neurons.MAIN OUTCOME MEASURES: ①Estimated measurement of the length of process and cell body during formation of neural EB after retinoic-acid induced differentiation of MESPU35 ESCs. ② Observation of cell morphology with immunocytochemical staining and proportion of differentiated cells assayed with FCM.RESULTS: ①It was discovered with phase contrast microscope that serum of different concentrations affect neural directional differentiation after EB formation to certain extent. Excessively high and low concentrations of serum reduced the proportion of neural differentiation of EB. The differentiating proportion is high in serum with 5% concentration. ② It is observed with immunocytochemical technique that the proportions of NF200 positive cell and glial fibrillary acidicprotein (GFAP) positive cell in differentiation of MESPU35 ESCs induced by retinoic acid were increased with phase spots in differentiation and increased concentration of retinoic acid. NF200 positive cell is transformed as multipolar neurons from absence of process in morphology. The processes of GFAP positive cell became longer and linked among each other as reticular pattern finally. ③ It was assayed with FCM that the proportion changes of GFAP positive cell and NF200 positive cell manufactured in differentiation were similar to immunocytochemical one.CONCLUSION: Retinoic acid in combination with proper concentration of serum and differentiating phase spots can induce neural-differentiation of MESPU35 ESC at high proportion and its differentiating regulation is in the patterns of concentration dependence and time dependence.

Objective To study the effect of ovarian estrogen on the expression of estrogen receptor beta (ER beta) of the basal forebrain of mice. Methods Ovariectomized (OVX) mice were used as animal model, and nickel ammonium sulfate intensified immunohistochemical SP technique was used to detect the changes of ER beta expression in the basal forebrain. Results The expression of ER beta in the basal forebrain of mice decreased dramatically, after OVX decreased to the lowest levels at 3 d after OVX, increased gradually, and recovered to normal level 20 d later. Conclusion Ovarain estrogen can regulate the expression of ER ? of the murine basal forebrain, indicating that estrogen, via ER ?, can regulate the nerous structure and function of the basal forebrain, which may be the mechanism of estrogen replacement therapy on Alzheimer′s brain.

In order to study the structure-function relationship in the protein which is incorporated with p-nitro-L-phenylalanine,the method of MD(Molecular Dynamics) simulation was established and successfully used in the analysis of protein which contains p-nitro-L-phenylalanine.The force field of CHARMM can only stimulate protein with natural amino acid in NAMD.Compared with phenylalanine,p-nitro-L-phenylalanine just has one more group of nitro.If the parameter of group of nitro was defined,the protein containing p-nitro-L-phenylalanine can be simulated.CGenFF-paramchem was used to calculate the energy and topological structure of p-nitro-L-phenylalanine' s new bonds (r),angles (θ),dihendrals (φ) and improper angle (ψ).And then the new defined parameter and topology information was input into the related parameter files and topology files in CHARMM.On the basis of correct parameter,NAMD can successfully simulate the modified BAFF(B lymphocyte stimulator) which contains p-nitro-L-phenylalanine.The changes in structure indicated that there might be new B cell epitopes.The temperature distribution of each frame in the process of dynamics stimulation was in accord with normal distribution,which proved the defined force field parameters was feasible.The RMSD of whole protein solution systemis 2.5.Calculate each resides' RMSF in BAFF,the RMSF of p-nitro-L-phenylalanine's residue is 3.7,which is obviously higher than that of the other residues in β-pleated sheet,and close to the loop rings,indicate that there might be variation in the area of p-nitro-L-phenylalanine residue and might produce new comformational epitopes.The results of MD stimulation will guide the immunogenicity experiments of p-nitro-L-phenylalanine modified proteins.
