Objective To study the correlation between the level of serum high sensitivity C-reactive protein (hs-CRP) and induced sputum cell counts,pulmonary function and asthma control test (ACT) in order to investigate the clinical application value of serum hs-CRP for the acute exacerbation bronchial asthma patients.Methods Thirty acute exacerbation bronchial asthma patients were collected as asthma group,14 healthy people during the same period were collected as control group.The fasting serum hs-CRP was examined in control group and before and after treatment of 5-7 d in asthma group.The induced sputum was obtained by ultrasonic atomizer 4.5％ sodium chloride,and the percentage of eosinophils (EOS％),neutrophil,macrophages,lymphocytes was calculated.The pulmonary function index was determined in control group and before and after treatment in asthma group.ACT score was performed in asthma group.The correlation between the serum hs-CRP and induced sputum differential leukocyte count,the pulmonary function index and ACT score was analyzed by Spearman correlation analysis.The effect of the serum hs-CRP and induced sputum EOS％ on inflammatory response of acute exacerbation bronchial asthma was evaluated by receiver operating characteristic (ROC) curve analysis.Results Two cases were excluded in asthma group.The serum hs-CRP before and after treatment in asthma group was higher than that in control group[4.18(2.12-11.12) and 3.40(2.02-8.91) mg/L vs.1.48(1.03-4.81) mg/L,H =18.939,P＜ 0.01].The serum hs-CRP before treatment was higher than that after treatment in asthma group (P ＜ 0.01).In asthma group,the serum hs-CRP had positive relationship with induced sputum EOS％ (r =0.849,P =0.000).There were negative correlations between the serum hs-CRP and the pulmonary function index such as one second forced expiratory volume percent predicted,one second forced expiratory volume occupied vital capacity ratio,maximum mid-expiratory flow percentage of predicted (r =-0.617,-0.559,-0.398,respectively,P =0.000,0.002,0.036,respectively).It was also found that the serum hs-CRP and ACT score had the remarkable Spearman linear correlation (r =-0.511,P =0.005).The area under the ROC curve of the serum hs-CRP was 0.713 (P =0.003).Conclusions There are significant correlations between the serum hs-CRP and induced sputum EOS％,pulmonary function,ACT score in the acute exacerbation bronchial asthma patients.It is found that hs-CRP could be considered as one of the potential marker to evaluate the systemic inflammation level of bronchial asthma.

Objective:To clarify the neuroprotective effects of neural cell adhesion molecule (NCAM) derived peptide P2 on in vitro cultured neuron and ischemic stroke rat. Methods:Primary cortical neurons were extracted and cultured, and CCK-8 method was used to observe the protective effect of different concentrations of P2 on cortical neurons under oxygen-glucose deprivation (OGD) conditions.The levels of apoptosis-related proteins and extracellular signal regulated kinase 1/2 (Erk1/2) were observed by Western blot. Clean grade male SD rats were selected for animal experiments. The middle cerebral artery occlusion (MCAO) method was used to establish the rat model of cerebral ischemia/reperfusion injury. The rats with successful model were divided into sham operation group, MCAO group and MCAO+ P2 group according to the random number table, with 12 rats in each group. After operation, rats in MCAO+ P2 group were subcutaneously injected with 1 mg/kg P2 once a day until 14 days after operation, and rats in the other two groups were subcutaneously injected with 0.9% sodium chloride solution of the same volume.Beam-walking test was used to evaluate the motor function of rats.Immunofluorescence staining and Western blot were used to detect the in-situ apoptosis of neuronal cells and the expression of Erk1/2 in ischemic penumbra of rat brains, respectively. All statistical analyses were performed using SPSS 22.0.Repeated measurement ANOVA was used to evaluate the beam-walking experimental data, and one-way ANOVA were used to analyze other experimental data among multiple groups.Results:Compared with OGD group, 0.5, 1.0 and 2.0 μmol/L P2 improved the activity of neurons under OGD conditions, of which 1 μmol/L P2 had the best effect ((2.436±0.284), (1.551±0.410), P<0.05). Western blot showed that the protein levels of bax ((76.120±3.232)%, (88.965±5.208)%, P<0.05), cleaved caspase-3 ((76.736±4.306)%, (97.781±8.111)%, P<0.05) and cleaved caspase-9 ((88.833±6.581)%, (104.962±4.788)%, P<0.05) in 1 μmol/L P2 treated group were all lower than those in OGD group, while the protein levels of bcl-2 ((56.146±3.882)%, (43.170±6.945)%, P<0.05) and phosphorylated Erk1/2 ((73.583±8.557)%, (55. 219±4.615)%, P<0.05) in 1 μmol/L P2 treated group were both higher than those in OGD group. Compared with MCAO group, on the 14th day after P2 intervention, the slip ratio of hindlimb of the paralyzed hind limbs of rats was lower ((23.438±11.540)%, (41.733±13.631)%, P<0.05), the apoptosis rate of neurons around the focus was lower ((13.144±6.485)%, (26. 699±6. 402)%, P<0.05), and the level of phosphorylated Erk1/2 protein in the brain tissues around the infarct focus was higher ((74.062±7.458)%, (53.327±7.093)%, P<0.05). Conclusion:Low doses of neural cell adhesion molecule derived peptide P2 exert neuroprotective effects on OGD neurons and ischemic stroke rats. The underlying mechanism may be related to the activation of Erk.

Stem cells have been a hot spot in medical research for a long time and have unique advantages in tissue repair, diagnosis and treatment of diseases. With the development of regenerative medicine, stem cells have been widely studied and applied in reproductive medicine, such as improving ovarian function and repairing endometrial damage. These efforts are achieved primarily through the use of mesenchymal stem cells(MSCs) from a variety of sources. However, the application of stem cells also faces problems such as low cell retention rate and medical ethics. This article focuses on the research progress and clinical application of MSCs (not involving embryonic stem cells) in the field of female reproductive medicine.
