OBJECTIVE To investigate the protective effects and potential mechanism of penehyclidine hydrochloride （PHC） on myocardial ischemia-reperfusion （I/R） injury in mice through the macrophage migration inhibitory factor （MIF）/adenosine monophosphate-activated protein kinase （AMPK） signaling pathways. METHODS Male C57BL/6 mice were randomly divided into sham operation group， I/R group， I/R+PHC group （PHC 20 μg/kg）， I/R+ISO-1 group （MIF inhibitor 35 mg/kg）， I/R+ PHC+ISO-1 group （with the same dosage as each single drug group）， with 8 mice in each group. Except for the sham operation group， the myocardial I/R injury model was prepared by coronary artery ligation. Thirty minutes before ligation， mice in each drug group were injected with 1 mL of the corresponding drug solution through the tail vein. After 120 min of reperfusion， the levels of cardiac function indexes [heart rate， stroke volume， ejection fraction， cardiac output， left ventricular posterior wall thickness in systole （LVPWs）， left ventricular posterior wall thickness in diastole （LVPWd）]， serum inflammatory factors [interleukin-6 （IL- 6）， IL-10， tumor necrosis factor-α （TNF-α）] in mice were detected in each group； the pathological changes and ultrastructure of myocardial tissue were observed， and the protein expressions of B cell lymphoma-2 （Bcl-2）， phosphorylated AMPKα （p-AMPKα） and MIF in myocardial tissue were detected. RESULTS Compared with the sham operation group， the myocardial cells in the I/R group were loosely arranged， with severe infiltration of inflammatory cells and obvious mitochondrial damage. Serum levels of IL-6 and TNF-α and protein expression of p-AMPKα in myocardial tissue were significantly increased or upregulated， while heart rate， stroke volume， ejection fraction， cardiac output， LVPWd and serum level of IL-10 were significantly decreased （P＜0.05）. Compared with the I/R group， the myocardial tissue lesions in the I/R+PHC group were alleviated； serum levels of IL-6 and TNF-α were decreased significantly， while heart rate， stroke volume， ejection fraction， cardiac output， LVPWs， LVPWd， serum level of IL-10， and protein expressions of Bcl-2， p- AMPKα and MIF in myocardial tissue were significantly increased or upregulated （P＜0.05）. However， myocardial tissue lesions of mice in the I/R+ISO-1 group worsened， with most quantitative indicators significantly deteriorating （P＜0.05）； MIF inhibitor could generally reverse the protective effect of PHC on I/R mice （P＜0.05）. CONCLUSIONS PHC can improve cardiac function， reduce myocardial inflammation， and restore the ultrastructure of myocardial tissue in I/R mice. These effects may be related to the activation of the MIF/AMPK signaling pathway.

Objective:To investigate the neuroprotective effect of histone deacetylase 3 (HDAC3) specific inhibitor RGFP966 on traumatic brain injury (TBI) and its mechanism in rats.Methods:Forty-eight SD rats were randomly divided into sham-operated group, TBI group, TBI+vehicle group and TBI+RGFP966 group ( n=12). Rats in the later 3 groups accepted hydraulic impact brain injury to establish TBI models; and then, RGFP966 (dissolved in 1% DMSO at a dose of 10 mg/kg) was injected intraperitoneally 30 min after modeling, twice a day for 3 d, in TBI+RGFP966 group; same amount of DMSO was injected into TBI+vehicle group at the same time. Three d after modeling, neurological function was tested by modified neurological severity score (mNSS), water content of brain tissues was detected by dry-wet weight method, proportion of injured neurons at the frontal cortical tissues on the affected side was detected by Nissl staining, expressions of HDAC3 and pyroptosis related proteins were detected by immunohistochemical staining and Western blotting, and serum content of inflammatory factors was detected by ELISA. Results:Three d after modeling, compared with the TBI+vehicle group, the TBI+RGFP966 group had significantly decreased mNSS scores (9.83±0.75 vs. 6.67±0.82), water content of the injured cerebral cortex (82.73%±0.36% vs. 80.92%±0.66%), proportion of damaged neurons (75.60%±7.44% vs. 55.87%±4.10%), and HDAC3 protein expression (0.67±0.09 vs. 0.51±0.07), and significantly increased acetylated H3 (Ace-H3) and acetylated H4 (Ace-H4) protein expressions (0.81±0.02 vs. 1.22±0.02; 0.74±0.01 vs. 1.07±0.02), and statistically decreased protein expressions of nuclear factor-κB (NF-κB, 1.20±0.05 vs. 0.94±0.04), NOD-like receptor thermal protein domain associated protein 3 (NLRP3, 0.72±0.02 vs. 0.40±0.03), Caspase-1 containing cysteine (Caspase-1), dermatin D N-terminal fragment (GSDMD-N, 0.71±0.03 vs. 0.52±0.01), significantly decreased NF-κB and NLRP3 immunohistochemical staining scores, and significantly decreased serum contents of tumor necrosis factor-α, interleukin(IL)-1β and IL-18 ( P<0.05). Conclusion:Early intervention with RGFP966 after TBI can reduce the pyroptosis and inflammatory reaction of nerve cells and play neuroprotective role, whose mechanism may be related to inhibited activation of NF-κB/NLRP3/GSDMD pathway.

Objective:To investigate the effects of positive end-expiratory pressure (PEEP) setting of mechanical ventilation guided by esophageal pressure in the treatment of patients with traumatic craniocerebral injury combined with acute respiratory distress syndrome (ARDS).Methods:The retrospective cohort study was conducted. From June 2016 to June 2018, 55 patients with traumatic craniocerebral injury combined with ARDS who met the inclusion criteria were admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University. According to PEEP setting method, 28 patients were allocated to esophageal pressure group (17 males and 11 females, aged (40±13) years) and 27 patients were allocated to PEEP-fractional concentration of inspired oxygen (FiO 2) table group (18 males and 9 females, aged (38±10) years). Patients in the 2 groups were treated with mechanical ventilation guided by lung protective ventilation strategy, and the optimal PEEP at 0 (immediately), 24, 48, and 72 h after treatment was determined according to esophageal pressure and PEEP-FiO 2 table, respectively. The mechanical ventilation parameters in the 2 groups were adjusted according to the optimal PEEP. The transpulmonary end-expiratory pressure, pulmonary compliance, oxygen index, central venous pressure, mean arterial pressure, and intracranial pressure at 24, 48, and 72 h after treatment were recorded. Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, independent sample t test, and Bonferroni correction. Results:The optimal PEEP of patients in esophageal pressure group at 0, 24, 48, and 72 h after treatment was (12.4±3.9), (11.2±3.5), (13.4±2.6), and (13.2±3.6) cmH 2O (1 cmH 2O=0.098 kPa), respectively, which was significantly higher than (8.2±2.5), (7.4±2.2), (8.3±2.3), and (8.5±2.5) cmH 2O in PEEP-FiO 2 table group, respectively ( t=4.702, 4.743, 7.849, 5.623 , P<0.01). The transpulmonary end-expiratory pressure and pulmonary compliance at 24, 48, and 72 h after treatment and oxygen index at 48 and 72 h after treatment of patients in esophageal pressure group were significantly higher than those in PEEP-FiO 2 table group ( t=17.852, 20.586, 19.532, 4.752, 5.256, 7.446, 2.342, 4.178, P<0.05 or P<0.01). The central venous pressure of patients in esophageal pressure group at 24, 48, and 72 h after treatment was significantly higher than that in PEEP-FiO 2 table group ( t=12.632, 5.247, 8.994, P<0.01), and there was no statistically significant difference in mean arterial pressure of patients between the 2 groups at 24, 48, and 72 h after treatment ( P>0.05). The intracranial pressure of patients in esophageal pressure group was higher than that in PEEP-FiO 2 table group at 24, 48, and 72 h after treatment, but there was no statistically significant difference between the 2 groups ( P>0.05). Conclusions:For patients with traumatic craniocerebral injury combined with ARDS, the optimal PEEP can be set under the guidance of esophageal pressure method, and the mechanical ventilation parameters adjusted according to the optimal PEEP can improve lung compliance and accelerate recovery of lung function more effectively, with no adverse effect in mean arterial pressure and intracranial pressure.

Objective:To investigate the value of growth differentiation factor-15 (GDF-15) and extravascular lung water index (EVLWI) in severity grading and prognosis prediction of patients with acute respiratory distress syndrome (ARDS).Methods:Patients with ARDS aged 18-75 years admitted to the department of respiratory intensive care unit (RICU) of Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2019 to February 2020 were enrolled. All patients were treated with conventional therapies such as mechanical ventilation, anti-infection, stabilization of water, electrolytes and acid-base environment, blood purification and nutritional support according to their conditions. Besides, the pulse-indicated continuous cardiac output (PiCCO) was performed after admission to the department, and EVLWI before treatment and at 24, 48 and 72 hours of treatment were recorded. Serum GDF-15 level was measured by enzyme linked immunosorbent assay (ELISA) during the same period. Patients were classified as mild, moderate, and severe degree according to the 2012 Berlin Definition of ARDS, and EVLWI and GDF-15 levels in patients with different disease levels before and after treatment were compared. In addition, the length of intensive care unit (ICU) stay, ICU mortality, and 28-day mortality of patients with different GDF-15 or EVLWI levels were analyzed comparatively, with the GDF-15 3 458 ng/L and EVLWI 15 mL/kg as the cut point.Results:A total of 82 patients with ARDS were enrolled, including 22 patients with mild ARDS, 28 patients with moderate ARDS, and 32 patients with severe ARDS. The GDF-15 and EVLWI levels in patients with moderate and severe ARDS at each time point before and after treatment were higher than those in patients with mild ARDS. Both GDF-15 and EVLWI levels in patients with severe ARDS were higher than those in the patients with moderate ARDS. The differences were statistically significant at all the time points except for the difference of GDF-15 levels at 24 hours after treatment (ng/L: 3 900.41±546.43 vs. 3 695.66±604.73, P > 0.05). [GDF-15 (ng/L): 3 786.11±441.45 vs. 3 106.83±605.09 before treatment, 3 895.48±558.96 vs. 3 333.29±559.66 at 48 hours, 3 397.33±539.56 vs. 3 047.53±499.57 at 72 hours; EVLWI (mL/kg): 19.06±1.91 vs. 14.31±1.50 before treatment, 18.56±2.23 vs. 13.26±1.69 at 24 hours, 17.23±1.76 vs. 12.45±1.36 at 48 hours, 15.47±1.81 vs. 11.13±2.19 at 72 hours, all P < 0.05]. According to the cut-off value, there were 23 patients with GDF-15 ≥ 3 458 ng/L and GDF-15 < 3 458 ng/L respectively and there were 23 patients with EVLWI ≥ 15 mL/kg and EVLWI < 15 mL/kg respectively. The length of ICU stay and 28-day mortality in patients with high GDF-15 were significantly higher than those in patients with low GDF-15 [length of ICU stay (days): 21.22±2.69 vs. 15.37±3.14, 28-day mortality: 56.5% vs. 21.7%, both P < 0.05]. The length of ICU stay and 28-day mortality in patients with high EVLWI were also significantly higher than those in patients with low EVLWI [length of ICU stay (days): 18.45±2.61 vs. 14.98±2.75, 28-day mortality: 47.8% vs. 17.4%, both P < 0.05]. Conclusion:To some extent, GDF-15 and EVLWI levels reflect the severity of patients with ARDS, and high GDF-15 and EVLWI levels are significantly associated with poor prognosis in patients with ARDS.

Objective:To prepare nanosilver-hybridized polylactic acid-glycolic acid copolymer (PLGA) microspheres loaded with simvastatin (SIM), and to evaluate its sustained release effect in vitro. Methods:The emulsification-solvent evaporation method was used to prepare SIM-loaded PLGA microspheres. Silk fibroin (SF) was used to modify the surface of SIM-loaded PLGA microspheres by hydrophobic interaction. Then, the microspheres were continually modified by electrostatic adsorption to chitosan (CTS) and nano-silver (AgNPs) to prepare SF-AgNPs-CTS-SF-SIM-PLGA microspheres. Scanning electron microscope, Fourier transform infrared spectrometer, energy spectrometer, Zeta potential meter were used to analyze the SIM-loaded microspheres. The external release properties of the SIM-loaded microspheres were also investigated.Results:The average diameter of the prepared PLGA microspheres was about 9.67 μm. The results of Fourier transform infrared spectroscopy and energy spectroscopy showed that the AgNPs-CTS-SF-SIM-PLGA microspheres have been successfully constructed. The Zeta potential results indicated that the SIM-loaded microspheres were all in a stable state. The in vitro release results showed that the SF-AgNPs-CTS-SF-SIM-PLGA microspheres had a good in vitro release effect, could delay the drug release rate and prolong the drug release time. Conclusions:The SF-AgNPs-CTS-SF-SIM-PLGA microspheres have antibacterial and osteogenic effects, and exhibit a good in vitro release effect. They can be used for local sustained-release administration in the oral cavity, which make makes them potentially useful in the treatment of periodontitis.

Objective To observe the effect of autophagy inhibitor on the activation of alcohol induced hepatic stel-late cells, and the mechanisms thereof. Methods HSC-T6 cells were cultured in vitro and divided into four groups, includ-ing blank control group, alcohol group, 5 mmol/L 3-MA+alcohol group (low alcohol group) and 10 mmol/L 3-MA+alcohol group (high alcohol group). RT-PCR was used to detect the expression levels ofα-smooth muscle actin (α-SMA) and typeⅠcollagen. The levels of LC3Ⅱ,α-SMA and typeⅠcollagen were detected by Western blot assay. The cell viability of HSC-T6 was detected by MTT assay. Results The mRNA expressions ofα-SMA, typeⅠcollagen and the protein of expressionsα-SMA, typeⅠcollagen and LC3Ⅱwere significantly up-regulated in alcohol group compared with those of control group (P<0.05), while the expressions of those parameters were significantly down-regulated in 10 mmol/L 3-MA+alcohol group (P<0.01). The mRNA and protein levels ofα-SMA and typeⅠcollagen were significantly decreased in two 3-MA-treated groups compared with those in alcohol group (P<0.05). Meanwhile, compared with the 5 mmol/L 3-MA+alcohol group,the protein expressions ofα-SMA, typeⅠcollagen and LC3Ⅱwere significantly decreased in10 mmol/L 3-MA+alcohol group (P < 0.05 ). Compared with the alcohol group,there was significantly lower proliferation activity in all two 3-MA-treated groups (P<0.05). Conclusion 3-MA can inhibit the protein expression of LC3Ⅱ,α-SMA and typeⅠcollagen induced by alcohol in HSC-T6 cells, and inhibit the proliferation of HSC cells.
