Objective To compare the effect of the oxytocin, dinoprostone suppositoriesository and cervical dilation balloon in odinopoeia of late pregnancy.Methods A total of 90 patients with late pregnancy singletons primipara were randomly divided into 3 groups with 30 cases in each group. Patients in the group A were treated by dinoprostone suppositoriesository, patients in the group B were treated by oxytocin, patients in the group C were treated by the cervical dilation balloon, the cervical, childbirth, complications and newborns in the 3 groups were observed and compared. Results Compared with group B and group C, late pregnancy induced labor curative effect in group A was better:cervical Bishop score was higher after intervention 6h and 12 h (P<0.05), and promote cervical mature rate and success rate of induced labor were higher(P<0.05), labor time was shorter (P<0.05).The incidence of delivery complications was lower(P<0.05).Conclusion Dinoprostone suppositories can reduce labor time significantly in the treatment of late pregnancy, and improve the success rate of induced labor, the effect is superior to oxytocin and cervical dilation balloon.

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

Objective To examine the effect function of platelet(Pt)assemble rate(PLTAR) and the change of protein kinase B(PKB) active by cilostazol (CS)and aspirin (AS)on elderly patients with acute coronary sydrome(ACS). Methods Forty-eight elderly patients with ACS were divided randomly into two groups:CS group (100 mg,n=26),AS group (300 mg,n=22).Twenty-six healthy elderly were into the group of normal control(NC group) . The CS group and AS group were treated by routine anticoagulation and antiplatelet.PLTAR and PKB activity were measured at 10 minutes before treatment and at 7 days after treatment 3.5,6.0,24.0 hours. Results The maximum PLTAR in elderly CS group and AS group was elevated significantly compared with NC group(P

Objective To investigate the effect of berberine on endoplasmic reticulum stress PERK apoptosis pathway in HK-2 cells by high fructose.Methods HK-2 cells were grown in DMEM/F12, containing 10% fetal bovine serum (FBS) and divided randomly into four groups: normal control group (Group C); Fructose group (Group F): it contains 25mmol/L fructose culture; Berberine group (Group B): 25mmol/L fructose + 10μmol/L berberine treatment group; TUDCA group (Group T):25mmol/L fructose +2μmol/L TUDCA culture group; Cells were collected after culturing 24h. The expression of glucose-regulated protein 78 (GRP78), CHOP protein and the phosphorylation levels of PERK, eIF2α were tested by Western blotting. The cell cycles were detected by flow cytometry and the apoptosis of cells were detected by TUNEL staining.ResultsWestern blotting showed that the expression of GRP78 and CHOP protein in group F was significantly higher than that in group C, and the levels of p-PERK and p-eIF2α in group F were significantly higher than those in group F. Compared with group F, GRP78, CHOP, p-PERK and p-eIF2α in group B and T were significantly lower (P<0.05). The expression of GRP78, CHOP, p-PERK and p-eIF2α in group B had no significant difference. Flow cytometry and TUNEL staining showed that the cell viability of fructose group was significantly lower than that of C group, and the apoptotic index was significantly higher than that of group C (P<0.05). Compared with group F, the activity of HK-2 cells in group B and T significantly increased, otherwise the apoptosis index significantly decreased, and the difference was statistically significant (P<0.05). Compared with group T, the viability index and apoptosis rate of group B had no significant difference (P>0.05).Conclusion Persistent high fructose can activate the intracellular PERK pathway in HK-2 cells, causing endoplasmic reticulum stress. Berberine can inhibit the fructose-induced PERK and eIF2α phosphorylation, down-regulated the expression of GRP78, CHOP protein, thus by regulating PERK Pathways to alleviate cell cycle arrest and reduce cell apoptosis.

Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.

BACKGROUNDProtectin D1 (PD1), derived from docosahexaenoic acid, has been shown to control and resolve inflammation in some experimental models of inflammatory disorders. We investigated the protective roles of protectin D1 in pulmonary inflammation and lung injury induced by lipopolysaccharide (LPS).

METHODSMice were randomly assigned to six groups (n = 6 per group): sham-vehicle group, sham-PD1 group, sham-zVAD-fmk group, LPS-vehicle group, LPS-PD1 group, and LPS-PD1-zVAD-fmk group. Mice were injected intratracheally with 3 mg/kg LPS or saline, followed 24 hours later by intravenous injection of 200 µg/mouse PD1 or vehicle. At the same time, some mice were also injected intraperitoneally with the pan-caspase inhibitor zVAD-fmk. Seventy-two hours after LPS challenge, samples of pulmonary tissue and bronchoalveolar lavage fluid were collected. Optical microscopy was used to examine pathological changes in lungs. Cellularity and protein concentration in bronchoalveolar lavage fluid were analyzed. Lung wet/dry ratios and myeloperoxidase activity were measured. Apoptosis of neutrophils in bronchoalveolar lavage fluid (BALF) was also evaluated by flow cytometry.

RESULTSIntratracheal instillation of LPS increased neutrophil counts, protein concentration in bronchoalveolar lavage fluid and myeloperoxidase activity, it induced lung histological injury and edema, and also suppressed apoptosis of neutrophils in BALF. Posttreatment with PD1 inhibited LPS-evoked changes in BALF neutrophil counts and protein concentration and lung myeloperoxidase activity, with the outcome of decreased pulmonary edema and histological injury. In addition, PD1 promoted apoptosis of neutrophils in BALF. The beneficial effects of PD1 were blocked by zVAD-fmk.

CONCLUSIONPosttreatment with PD1 enhances resolution of lung inflammation during LPS-induced acute lung injury by enhancing apoptosis in emigrated neutrophils, which is, at least in part, caspase-dependent.
