[Objective] To explore the cytoprotecfion of hydrogen sulfide (H_2S) against cobalt chloride (CoCl_2)-induced apeptosis in PC12 cells and the underlying mechanisms. [Methods] CoCl_2 (a chemical hypoxia-mimetic agent) was used to establish the chemical hypoxia-induced PC12 cell injuries model. Sodium hydrosulfide (NaHS) was used as a H_2S donor. The viability of PC12 cells was measured by CCK-8 assay. The percentage of apeptotic cells was assessed by propidium iodide stain flow cytometry (FCM). The morphological change of apeptotic cells was tested by using the chromatin dye Hoechst 33258. The mitochondrial membrane potential (MMP) was analyzed by rhodamine 123 staining and photofluorography. The level of reactive oxygen species (ROS) in PC12 cells was measured by DCFH-DA staining and photofluorography. [Results] CoCl_2 induced a decrease in cell viability and an increase in percentage of apeptosis in PC12 cells along with dissipation of MMP as well as overproduction of ROS. When PC12 cells were treated with Naris 30 min before CoCl_2 treatment a decrease in viability of PC12 cells induced by 600 μmol/L CoCl_2 was concentration-dependently blocked by NaHs (100, 200, and 400 μmol/L). Pretreatment with NaHS at 200 and 400 μmol/L obviously reduced the apepetotic percentage of PC12 cells induced by 600 μmol/L CoCl_2 and inhibited the dissipation of MMP and overproduction of ROS. [Conclusion] H_2S protected PC12 cells against CoCl_2-induced apeptosis, which may be associated with the inhibition of H_2S on the dissipation of MMP and overproduction of ROS induced by CoCl_2.

Objective: To investigate the causal relationship between antioxidant nutrients and pregnancy complications, so as to provide the reference for the prevention and treatment of pregnancy complications. Methods: Data of seven antioxidant nutrients including vitamin A, vitamin C, vitamin E, selenium, zinc, copper and iron were collected from genome-wide association study (GWAS) Catalog database, and data of four pregnancy complications including gestational diabetes mellitus, pre-eclampsia, spontaneous abortion and preterm birth were collected from the Finland database. Single nucleotide polymorphism (SNP) data were collected, and 27 SNPS strongly correlated with seven antioxidant nutrients were selected as instrumental variables. Mendelian randomization (MR) analyses were performed using the inverse-variance weighted (IVW) method with seven antioxidant nutrients as exposures factors and four pregnancy complications as outcome variables. The heterogeneity was assessed using the Cochran's Q test, the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression, and the robustness of the results was verified with the leave-one-out. Results: Cochran's Q test showed heterogeneity of MR results between vitamin C and gestational diabetes mellitus, preeclampsia and preterm birth, between vitamin E and iron and gestational diabetes (all P<0.05), and a random effect model was employed. There was no heterogeneity in other results (all P>0.05), and a fixed effect model was employed. MR analysis results showed that there was no causal association between seven antioxidant nutrients and the risk of four pregnancy complications (all P>0.05). MR-PRESSO test and the MR-Egger regression identified no horizontal pleiotropy of instrumental variables (both P>0.05). Conclusion This study did not find genetically predicted associations of antioxidant nutrients with pregnancy complications.

Objective To investigate the correlation and consistency between the parameters of thromboelastography(TEG)and routine coagulation tests,and to evaluate the application value of the two methods in heparin anticoagulation monitoring and coagulation function monitoring in patients receiving extracorporeal membrane oxygenation(ECMO)therapy.Methods A total of 138 patients who recieved ECMO in the Department of Critical Care Medicine of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2021 to December 2022 were selected.A total of 317 pairs of ordinary TEG and heparinase-modified TEG(hmTEG)parameters measured simultaneously were analyzed for correlation and consis-tency with activated partial thromboplastin time(APTT),fibrinogen(Fib),and platelet count(Plt),and the parameters tested when ECMO was established and 24 hours after ECMO operation were compared.Results The correlation coefficient between R values and APTT of hmTEG(r=0.441,P<0.05)was lower than that of ordinary TEG(r=0.547,P<0.05).The parameters α-Angle and K value of ordinary TEG were not correlated with Fib(P>0.05),while as for hmTEG,the correla-tion was 0.359(P<0.05)and-0.343(P<0.05),respectively.The correlation between MA value of hmTEG and Plt was 0.456(P<0.05),which was much lower than its correlation with Fib(r=0.715,P<0.05).APTT and hmTEG had moderate agreement in judging the anticoagulant effect of UFH(P<0.05).Plt at 24 hours after ECMO was significantly lower than that at establishment of ECMO(P<0.05).Fib,APTT and hmTEG parameters were not significantly different between the two groups(P>0.05).Conclusion The parameters of hmTEG can better reflect the real level of coagulation factors in patients receiving ECMO.The results of hmTEG and APTT are complementary to assess whether heparin in ECMO patients is over-dosed,and hmTEG has unique advantages.Routine coagulation tests and TEG cannot replace each other,and the combina-tion of them can achieve better anticoagulation and coagulation management.

Objective:To investigate the role and probable mechanism of miRNA-181a in nonalcoholic fatty liver disease.Methods:HepG2 cells were treated with palmitic acid to construct a nonalcoholic fatty liver disease cell model, and the expression of miR-181a and lipidosis in the cells were measured. Transforming growth factor-β (TGF-β) was used to examine the effect of miR-181a expression in HepG2 cells. The miR-181a, lipidosis, reduced glutathione and reactive oxygen species (ROS) were determined by controlling and regulating the miR-183 expression levels after transfection with miR-181 mimics and inhibitors in HepG2 cells. The miR-181a target genes were predicted by bioinformatics analysis, and verified by real-time fluorescent quantitative PCR and western blotting. The independent sample t-test was used for the comparison between the two independent samples, and the comparison between multiple groups were accorded with the normal distribution, homogeneity of variance, and one-way analysis of variance.Results:Lipidosis was significantly increased after palmitic acid treatment in HepG2 cells, and the expression level of miR-181a was significantly increased than control group. After HepG2 cells were transfected with miR-181a inhibitors, the expression of miR-181a, triglycerides and reactive oxygen species were down-regulated, and reduced glutathione, predicting the mRNA and protein expression of target gene silencing information regulator 2 related enzyme 1 were up-regulated. However, the results were contrary to the above changes after transfection with miR-181a mimics.Conclusion:miR-181a participates in lipidosis and promotes lipid peroxidation in nonalcoholic fatty liver disease. miR-181a may affect the pathogenesis and progression of nonalcoholic fatty liver disease by inhibiting the expression of silencing information regulator 2 related enzyme 1.

AIM: To compare the effects of different doses of alfentanil on tracheal intubation conditions, hemodynamic parameters and recovery quality in children undergoing tonsillectomy. METHODS: Ninety children undergoing tonsillectomy were randomly divided into 3 groups, and received alfentanil 20 μg/kg (A20 group), 40 μg/kg (A40 group) and 60 μg/kg (A60 group) for anesthesiainduction respectively, 30 cases in each group. The remaining anesthesia induction and maintenance protocols were the same. The Helbo-Hansen scores of the three groups were evaluated, and the MAP and HR before anesthesia induction (T0), before tracheal intubation (T1), immediately after tracheal intubation (T2), and 1 min after intubation (T3) as well as the recovery time of spontaneous breathing, eye opening time, extubated time, agitation score in PACU, and adverse drug reactions were recorded. RESULTS: Compared with A20 group, the total values of Helbo-Hansen score and cough scores in group A40 and A60 were lower (P<0.05). Compared with T0, the MAP at T1-T3 were decreased in group A40 and A60, and HR increased at T2 and T3 in group A20 while HR slowed down at T1 in group A40, and at T1-T3 in group A60 (P<0.05). Compared with A20 group, children in group A40 had lower MAP and slower HR at T1-T3, while those in group A60 had lower MAP and slower HR at T1-T3 (P<0.05). The recovery time of spontaneous breathe and extubated time were prolonged in group A60 (P<0.05). CONCLUSION: During the anesthesia induction period of tonsillectomy in children, both afentanil 40 μg/kg or 60 μg/kg combined with propofol 3 mg/kg and rocuronium 0.3 mg/kg can provide satisfactory intubation condition, while the vital signs are more stable during anesthesia induction in afentanil 40 μg/kg group and rapid extubation after operation can be achieved.

BACKGROUNDS: Cardiovascular disease (CVD) remains the leading cause of deaths nationwide. However, little is understood about its temporal trend and corresponding influence on longevity improvements. We aimed to describe the updated tendency in CVD mortality and to quantify its impact on life expectancy (LE) increase in China. METHODS: All-cause mortality rates were calculated with population sizes from the National Bureau of Statistics and death counts from the National Health Commission. We estimated CVD mortality rates by allocating age- and sex-based mortality envelopes to each CVD subtype based on its proportion derived from the Disease Surveillance Points system. The probability of CVD premature deaths and LE were calculated with life tables and we adopted Arriaga's method to quantitate age- and cause-specific contributions to LE gains. RESULTS: During 2013 to 2018, the age-standardized mortality rate of CVD decreased from 289.69 (95% confidence interval [CI]: 289.03, 290.35)/100,000 to 272.37 (95%CI: 271.81, 272.94)/100,000, along with a decline in probability of CVD premature deaths from 9.05% (95%CI: 9.02%, 9.09%) to 8.13% (95%CI: 8.10%, 8.16%). The gap in CVD mortality across sexes expanded with more remarkable declines in females, especially for those aged 15 to 64 years. Among major subtypes, the probability of premature deaths from hemorrhage stroke declined fastest, while improvements of ischemic stroke and ischemic heart disease were limited, and there was an increase in stroke sequelae. LE in China reached 77.04 (95%CI: 76.96, 77.12) years in 2018 with an increase of 1.38 years from 2013. Of the total LE gains, 21.15% (0.29 years) were attributed to reductions of CVD mortality in the overall population, mostly driven by those aged >65 years. CONCLUSIONS The general process in reducing CVD mortality has contributed to longevity improvements in China. More attention should be paid to prevention and control of atherosclerotic CVD and stroke sequelae, especially for the elderly. Working-age males also deserve additional attention due to inadequate improvements.

BACKGROUND: The clinical trials of new anti-tumor drugs are prospering in China. The acceptance of clinical trials in patients is an important factor affecting the speed and quality of clinical trials. Previous studies have investigated the acceptance of clinical trials in those cancer patients, who have never participated in a trial. This study is designed to investigate and compare the acceptance and related causes of clinical trials in cancer patients who have once participated in a clinical trial or not. METHODS: From June 2018 to April 2019, a standardized questionnaire-based survey was conducted among two groups of cancer patients classified by history of clinical trial participation in Cancer hospital, Chinese Academy of Medical Science, mainly focusing on their overall acceptance of clinical trials and related considerations, including the role of attending doctors, as well as group differences between the two participants. RESULTS: A total of 538 patients were enrolled with an average age of 53.5 years old, 51.1% of whom were males, and 43.3% of whom have never participated in a clinical trial. Overall, 502 patients (93.3%) were willing to or recommend their relatives or friends to participate in clinical trials, and patients with history of clinical trial participation had higher willingness (96.6% vs 90.8%, P=0.008). Patients were most likely to be motivated by expectation of optimal treatment (100.0% vs 99.3%) for both those who had once participated in a clinical trial or those not, respectively followed by financial burden reduction (56.0%) and recommendation by attending doctor (43.7%). The main reasons for unwillingness-to-participate for those who had once participated in a clinical trial were abandoning other treatment options, divided into control group or additional visits, while for those who had never participated in a clinical trial, ineffective treatment or serious adverse reactions were their main concerns. In the decision-making of clinical trial participation, 88% patients highly valued the role of recommendation by attending doctors. Among patients without trial participation history, 60.9% of those had no unwillingness-to-participate expressed that recommendation by attending doctors would change their decisions. The study also reported patients' preferences for information and access to clinical trials. CONCLUSIONS The acceptance of clinical trials in cancer patients in our hospital is generally high, especially in patients who had a history of trial participation. It's of substantial significance to give full play to the role of doctors in improving the acceptance of clinical trials of cancer patients in China.
