Objective:To observe the effect of noninvasive positive pressure ventilation (NIPPV) and high-flow nasal cannula oxygen therapy (HFNC) on the prognosis of patients with coronavirus disease 2019 (COVID-19) accompanied with acute respiratory distress syndrome (ARDS).Methods:A retrospective study was conducted in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology when authors worked as medical team members for treating COVID-19. COVID-19 patients with pulse oxygen saturation/fraction of inspiration oxygen (SpO 2/FiO 2, S/F) ratio < 235, managed by medical teams [using S/F ratio instead of oxygenation index (PaO 2/FiO 2) to diagnose ARDS] from February to April 2020 were included. The patients were divided into NIPPV group and HFNC group according to their oxygen therapy modes. Clinical data of patients were collected, including general characteristics, respiratory rate (RR), fraction of FiO 2, SpO 2, heart rate (HR), mean arterial pressure (MAP), S/F ratio in the first 72 hours, lymphocyte count (LYM), percentage of lymphocyte (LYM%) and white blood cell count (WBC) at admission and discharge or death, the duration of dyspnea before NIPPV and HFNC, and the length from onset to admission. The differences of intubation rate, all-cause mortality, S/F ratio and RR were analyzed, and single factor analysis and generalized estimation equation (GEE) were used to analyze the risk factors affecting S/F ratio. Results:Among the 41 patients, the proportion of males was high (68.3%, 28 cases), the median age was 68 (58-74) years old, 28 cases had complications (68.3%), and 34 cases had multiple organ dysfunction syndrome (MODS, 82.9%). Compared with HFNC group, the proportion of complications in NIPPV group was higher [87.5% (21/24) vs. 41.2% (7/17), P < 0.05], and the value of LYM% was lower [5.3% (3.4%-7.8%) vs. 10.0% (3.9%-19.7%), P < 0.05], the need of blood purification was also significantly lower [0% (0/24) vs. 29.4% (5/17), P < 0.05]. The S/F ratio of NIPPV group gradually increased after 2 hours treatment and RR gradually decreased with over time, S/F ratio decreased and RR increased in HFNC group compared with baseline, but there was no significant difference in S/F ratio between the two groups at each time point. RR in NIPPV group was significantly higher than that in HFNC group after 2 hours treatment [time/min: 30 (27-33) vs. 24 (21-27), P < 0.05]. There was no significant difference in rate need intubation and hospital mortality between NIPPV group and HFNC group [66.7% (16/24) vs. 70.6% (12/17), 58.3% (14/24) vs. 52.9% (9/17), both P > 0.05]. Analysis of the factors affecting the S/Fratio in the course of oxygen therapy showed that the oxygen therapy mode and the course of illness at admission were the factors affecting the S/F ratio of patients [ β values were -15.827, 1.202, 95% confidence interval (95% CI) were -29.102 to -2.552 and 0.247-2.156, P values were 0.019 and 0.014, respectively]. Conclusion:Compared with HFNC, NIPPV doesn't significantly reduce the intubation rate and mortality of patients with COVID-19 accompanied with ARDS, but it significantly increases the S/F ratio of those patients.

The proportion of HT- 29 cells at G 2/M phase in TAG groups as well as those at G 0/G1 phase in medium-dose group were increased significantly ；the proportion of HT- 29 cells at S phase in TAG groups as well as those at G 0/G1 phase in high-dose group were decreased significantly （P＜0.05 or P＜0.01）. Survival rate ，migration rate and invasion rate of HUVEC were decreased significantly in TAG groups ，and tube number was also decreased significantly at each time point during 4-24 h（P＜0.01）. CONCLUSIONS ：TAG have inhibitory effect on the proliferation of human colon cancer HT- 29 cells and HUVEC，can change HT- 29 cell cycle ，inhibit the migration ，invasion and tube formation of HUVEC.

Objective To observe the serum cortisol level in ischemic stroke patients with obstructive sleep apnea syndrome (OSAS),and discuss the influence factors and its correlation with severity of cerebral infarction.Methods Two hundred ischemic stroke patients with onset of 6 h to 3 weeks,admitted to our hospital from July 2015 to April 2017,were recruited;all patients were monitored with polysomnography.According to apnea hypopnea index (AHI),all patients were divided into ischemic stroke without OSAS group (AHI＜5/h,n=89) and ischemic stroke with OSAS group (AHI≥ 5/h,n=111).Moreover,according to AHI,patients from ischemic stroke with OSAS group were divided into three subgroups,namely,mild subgroup (5/h ≤AHI＜15/h),moderate subgroup (15/h ≤AHI＜30/h) and severe subgroup (AHI ≥30/h).According to National Institutes of Health Stroke Scale (NIHSS) scores,all subjects were divided into a group of NIHSS scores no more than 10 and a group of NIHSS scores＞10.The general clinical data,biochemical indices,early morning blood pressure,serum cortisol level and sleeping parameters were detected and compared among the groups,and the main factors affecting serum cortisol levels were identified by multivariate linear regression analysis.Results (1) The serum cortisol level in ischemic stroke with OSAS patients ([195.41±75.31] μg/L) was significantly higher than that of ischemic stroke without OSAS patients ([158.65±77.28] μg/L,P＜0.05);the serum cortisol level in ischemic stroke with mild OSAS subgroup ([227.32±75.12] μg/L) was significantly increased as compared with that in the ischemic stroke with moderate OSAS subgroup and ischemic stroke with severe OSAS subgroup ([191.27±71.50] μg/L and [175.21±75.13] μg/L,P＜0.05).(2) The serum cortisol level of group of NIHSS scores＞10 was significantly higher than that of group of NIHSS scores ≤ 10 (P＜0.05).(3)AHI,NIHSS scores,longest duration of apnea,and lowest blood oxygen saturation at night had significant effects on serum cortisol levels.Serum cortisol levels increased with AHI (β=89.984,95％CI:71.325-108.644,P=0.000) and NIHSS scores (β=0.923,95％CI:0.377-1.468,P=0.001),increased with the longest sleep apnea (β=0.804,95％CI:0.262-1.325,P=0.000),and decreased with the lowest blood oxygen saturation at night (β=-0.709,95％CI:-0.290--0.041,P=0.000).Conclusion The serum cortisol level in cerebral infarction patients with OSAS was increased,and the higher the severity of cerebral infarction and OSAS is,the higher the serum cortisol level is.

Objective To analyze the role of a key intracellular signaling molecule GSK3β in hepatocyte apoptosis induced by endoplasmic reticulum stress (ERS).Methods Using mouse hepatoma cell lines(Hepa 1) as cell apoptosis model triggered by tunicamycin,an endoplasmic reticulum stress inducer.One hour before Hepa 1 apoptosis induced by tunicamycin,SB216763 specifically inhibited the activity of GSK3β.Living cells/apoptotic cells were detected using acetoxymethyl (AM)/propidium iodide (PI) staining; Furthermore,the measurement of lactate dehydrogenase(LDH) of cell culture supernatant to evaluate the apoptosis.We detect p-GSK3β,GSK3β,the ERS-related protein(GRP78,CHOP and caspase-12) and caspase-3,cleaved caspase-3 protein expression using Western blot.Results Endoplasmic reticulum stress induced by tunicamycin promotes GSK3β activity; Inhibition of GSK3β activity alleviates endoplasmic reticulum stress:the expression of GRP78,CHOP and caspase-12 expression are inhibited.At the same time,GSK3β activity inhibition significantly reduced the endoplasmic reticulum stress-induced apoptosis:compared to cell apoptosis model group,the intervention group of SB216763 showed that the level of LDH decreased significantly,and PI staining of apoptotic cells was also significant reduction.Western blot results showed that the inhibition of GSK 3 β activity reduced reactive cleaved caspase-3 protein.Conclusion GSK3β is an important signaling molecule in the apoptosis pathway induced by endoplasmic reticulum stress ;Endoplasmic reticulum stress promotes hepatocyte apoptosis by mediating GSK3β.

AIM: To explore the roles of heat shock protein 90 (HSP90) in the blockage of hydrogen sulfide (H2S) against chemical hypoxia-mimetic agent (cobalt chloride, CoCl_2)-induced oxidative stress injuries in H9c2 cardiac cell. METHODS: H9c2 cells were treated with CoCl_2 to set up the chemical hypoxia-induced the model of cardiomyocyte injury. Sodium hydrosulfide (NaHS, a H2S donor) was added into medium for 30 min before CoCl_2 treatment. ATP content was detected by high performance liquid chromatogram (HPLC). Mitochondrial membrane potential (MMP) was measured by rhodamine123 (Rh123) staining and photofluorography. The activity of superoxide dismutase (SOD) was observed using a SOD kit. The expression of heme oxygenase-1 (HO-1) was evaluated by Western blotting. RESULTS: CoCl_2 at concentration of 600 μmol/L significantly reduced SOD activity, ATP level and MMP, and enhanced the expression of HO-1 in H9c2 cells. Pretreatment with 400 μmol/L NaHS dramatically inhibited the cytotoxicity induced by CoCl_2, increased SOD activity, ATP level and MMP, decreased HO-1 expression. 17-allylamino-17 demethoxygeldanamycine(17AAG), an inhibitor of HSP90, obviously blocked the inhibitory effect of H2S on the CoCl_2-induced cytotoxicity, reduced the levels of ATP and MMP, increased HO-1 expression. However, no significantly influence on SOD activity was observed. CONCLUSION: HSP90 may mediate the cardioprotection of H2S via inhibiting the oxidative stress induced by chemical hypoxia.
