Chinese Circulation Journal 2015;(12):1191-1194
Objective: To explore the clinical efficacy of positive airway pressure biphasic (BiPAP) non-invasive ventilation for treating the patients with severe pre-eclampsia combining acute heart failure (AHF).
Methods: A total of 84 patients with severe pre-eclampsia combining AHF treated in our hospital from 2008-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups: Control group, the patients received routine treatment for pre-eclampsia and AHF,n=41 and Observation group, based on routine treatment, the patients received assistant BiPAP ventilation,n=43. The changes at before and 3h after treatment of cyanosis, dyspnea, pulmonary rales, heart rate (HR), respiratory rate (RR), arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2), arterial carbon dioxide partial pressure (PaCO2), pH value and plasma levels of BNP were compared between 2 groups.
Results:①Comparison of before vs after treatment in both groups: HR (times/min) in Control group (90±8 vs 110±14) and Observation group (80±6 vs 112±12); RR (times/min) in Control group (24±5 vs 33±8) and Observation group (18±4 vs 35±7); PaCO2 (mmHg) in Control group (41.3±4.3 vs 48.4±5.6) and Observation group (29.7±5.4 vs 47.8±3.9); BNP (ng/L) in Control group (87.50±8.00 vs 133.00±8.00) and Observation group (69.50±8.30 vs 138.00±6.92); SaO2 (%) in Control group (93.0±3.7 vs 80.5±4.7) and Observation group (97.1±3.4 vs 81.2±4.2); PaO2 (mmHg) in Control group (80.3±5.8 vs 80.5±4.7) and Observation group (89.1±6.2 vs 53.2±5.4), allP<0.05.②After treatment, compared with Control group, Observation group presented obviously decreased HR, RR, PaCO2 and BNP; signiifcantly increased SaO2 and PaO2, allP<0.05. PH was similar between 2 groups,P>0.05.
Conclusion: Assistant BiPAP ventilation may treat the patients with severe pre-eclampsia combining AHF, it could improve HF symptom and hypoxia. The clinical signiifcance should be conifrmed by further investigation.

Objective To study the clinical efficacy and effects on CRP levels of ambroxol in treatment of pulmonary infections.Methods 68 patients with pulmonary infection were selected and divided into the observation group(n =34)and control group by using the random number table method(n =34).The observation group was treated with ammonia bromine atomization inhalation treatment,while the control group was treated with alpha chymo-trypsin atomization inhalation therapy.The clinical effect and duration of symptoms and signs disappeared of the two groups were compared,and serum CRP level changes in the two groups before and after treatment were also compared. Results After treatment,the clinical total effective rate was 91.2% of the observation group.And the total effective rate was 70.6% in control group,the comparison between the two groups had statistically significant difference (χ2 =4.316,P <0.05).Compared with the control group,the observation group patients symptoms disappear time(3.1 ± 0.5)d,pulmonary symptoms disappear time(4.1 ±1.7)d,body temperature returned to normal time(4.1 ±1.6)d and hospital stay(8.4 ±2.8)d were significantly shortened,the differences were statistically significant (t =2.879, 2.918,3.025,3.972,all P <0.05 ).The serum CRP levels in patients of the observation group was (22.45 ± 9.27)mg/L,which of the control group was (33.45 ±14.67 )mg/L,both were significantly lower than before treatment,the difference was statistically significant (t =6.314,5.126,all P <0.05).The lower degree of serum CRP level in the observation group was obviously better than tha in the control group,the difference was statistically significant (t =6.263,P <0.05).Conclusion The ambroxol can achieve significant clinical effect on treatment of pulmonary infections,which can significantly shorten the patientˊs symptoms and lung signs disappear time and length of hospital stay,etc.It can reduce the serum CRP level,and is worth popularization and application in clinic.

BACKGROUND: Macrophage colony-stimulating factor (M-CSF)/receptor activator of nudeer kappa B ligand (RANKL), two types of cytokines co-induce myeloid stem cells to form osteoclasts, is a kind of new method to harvest ostaoclasts with high purity and quantity, but there is lack of uniform cultivation standard. OBJECTIVE: To construct an effective M-CSF/RANKL induced mice myeloid stem cells inducing osteoclast differentiation cultivation system. METHODS: Myeloid stem cells ware obtained from ICR mice and then cultured for 24 hours in a-minimum essential medium containing M-CSF, at cell density of 10~7/L, 10~8/L, 10~9/L. Then 10 μg/L M-CSF and 20, 50, 100 μg/L RANKL were added into culture medium. Tartaric-resistant acid phosphatase stained was performed to observe the transition process from stem cell to osteoclast, as well as cell morphology and stain situation after culture, and positive stained osteoclasts were counted. We compared the influence of different induction conditions to the quantity of osteoclast. RESULTS AND CONCLUSION: A small quantity of osteoclasts contained many red positive beads in the intracytoplasm were observed at 3 days. There were positive beads with hypochromatic dikeryon in cells. A large amount of positively stained osteoclests were seen after 6-day cultudng, which maintained dikaryon. After 9-day culturing, positively stained colossal multinudear cells occurred, became larger and maintained three nuclei. At certain cell density, 100 μg/L RANKL could induce to form more osteoclasts compared with other 2 concentrations (P < 0.05); at certain RANKL concentration, the osteoclasts formation at cells density of 10~8/L was dramatically greater than other 2 cell densities (P < 0.05); the number of osteoclasts was the most when the concentration of RANKL was 100 μg/L and cell density of 10~8/L (P < 0.05). When osteoclasts are induced by M-CSF/RANKL from mudne myeloid stem cells, the best concentration of RANKL is 100 μg/L and cells density is 10~8/L.

Objective To estimate effects of AG490, a selective inhibitor of JAK2/STAT3 signaling pathway, on the biological behavior of human keloid?derived fibroblasts (HKFs), and to explore their possible mechanisms. Methods In vitro cultured human skin fibroblasts(HSFs)and HKFs were both divided into several groups to be treated with AG490 at different concentrations (12.5, 25, 50, 75, 100 μmol/L), with those receiving no treatment serving as the control group. Then, cell counting kit?8(CCK?8)assay was performed to evaluate cellular proliferative activity of HSFs and HKFs after 24?, 48?and 72?hour treatment, flow cytometry to estimate cell cycle distribution and apoptosis rate in HKFs after 24?hour treatment, reverse transcription(RT)?PCR to measure STAT3 and cyclin D1 mRNA expressions in treated HKFs as well as STAT3 mRNA expression in untreated HSFs and HKFs after 24?hour culture, and Western blot analysis to measure the protein expressions of STAT3 and p?STAT3 in HSFs and HKFs after 24?hour treatment. Results CCK?8 assay showed that the proliferation inhibition rates of both HSFs and HKFs gradually increased along with the increase in AG490 concentrations and treatment duration, and the inhibitory effects increased in both dose?and time?dependent manners(all P<0.05). Besides, when cells were treated with the same concentrations of AG490 for same durations, the proliferation of HKFs were inhibited to a greater extent than that of HSFs(all P<0.05). As flow cytometry revealed, along with the increase of AG490 concentrations, the proportion of HKFs in G1 phase and the apoptosis rate in HKFs both increased gradually(all P < 0.01), while the proportion of HKFs in G2 phase gradually decreased(all P < 0.01), and the proportion of HKFs in S phase remained insignificantly changed. RT?PCR showed that the mRNA expression of STAT3 was significantly higher in untreated HKFs than in untreated HSFs after 24?hour normal culture(P < 0.05). After 24?hour treatment with AG490, the mRNA expressions of STAT3 and cyclin D1 in HKFs gradually decreased with the increase of AG490 concentrations. Correlation analysis revealed that the mRNA expression of cyclin D1 was positively correlated with that of STAT3 in AG490?treated HKFs (r = 0.855, P < 0.01). Western blot analysis showed that the protein expressions of both STAT3 and p ? STAT3 gradually decreased in HKFs and HSFs along with the increase of AG490 concentrations(all P < 0.05), and were significantly lower in HKFs than in HSFs (both P < 0.05). Conclusion AG490 can effectively inhibit HKF proliferation by selectively blocking the JAK2/STAT3 signaling pathway.
