Objective To investigate the effects of tanshinol on the proliferation,apoptosis and NF-?B activation in rat hepatic stellate cells(HSCs) after IL-1? inducement,and to elucidate the anti-fibrotic molecular mechanisms of tanshinol.Methods The rat HSCs was isolated with collagenase in situ liver recirculation perfusion and cultured in vitro.The cells were divided into 5 groups: normal control,IL-1? treatment group(10 ng/ml),and tanshinol group 1,2 and 3.The later 3 groups were pretreated with tanshinol at the concentrations of 0.062 5,0.125 and 0.25 mmol/L respectively followed by 10 ng/ml IL-1? treatment 1 h later.MTT colorimetric assay was used to detect the proliferation of HSCs.AO/EB immunoflurorescence microscopy and combination Annexin-V-FITC/PI double-labelimmunofluorescence with flow cytometer were employed to examine the apoptosis of HSCs.Synthesis and secretion of collagen Ⅲ were detected by the quantitative immunocytochemical assay and ELISA respectively.The amounts of cytoplasm p-I?B? and NF-?B p65,and nuclear NF-?B p65 in HSCs were determined by Western blotting.Immunocytochemical staining and Western blotting were used to observe nuclear translocation of NF-?B p65.Results IL-1? increased the proliferation of HSCs(P

Objective To investigate the error monitoring function damages on the patients with schizo?phrenia ( SCH) . Methods A total of 32 patients with schizophrenia were compared with matched 34 health con?trols ( HC) on the error monitoring tasks which were compiled by E?Prime. Results The comparison between SCH group ((713.22±174.52)ms,( 491.14±170.29) ms,( 1060.31±130.84) ms,(8.28±12.55)time,( 8.00± 7.53)time respectively) and HC group ((560.73±156.94) ms,(395.62±188.03) ms,(989.85±104.33) ms, (2.97±4.13) times,(3.12±6.50) times) on the reaction time of choice,assessment,incongruent condition,the numbers of uncertain and the numbers of dropout were significant ( t=-3.737, P=0.000;t=-2.159, P=0.035;t=-2.426, P=0.018;t=-2.282, P=0.022;t=-2.824, P=0.006) . The SCH group and HC group did not signifi?cantly difference in Full Correct((124.72±23.74)/(131.74±21.96)times),Full Error((15.69±17.64)/(13.35± 18.63)times),Part Correct((6.83±10.40)/(4.21±7.03)times),Part Error((2.91±10.91)/(0.62±1.10)times) and Accuracy((0.831±0.161)/(0.874±0.159))(P>0.05).There was no significantly correlation among the course of disease,HAMA,HAMD and the error monitoring. Conclusion These results demonstrate that the error monitoring function damages on the patient with SCH may be involved in the dysfunction of anterior cingulate cortex.

Objective To evaluate the safety and effectiveness of the treatment by selective β 1 receptor blockers on patients with chronic obstructive pulmonary disease (COPD).Methods Eighty cases of COPD Ⅲ (stable period) inpatient with or without coronary heart disease were collected in The Second People's Hospital of Shanghai from September 2012 to November 2013.The patients were randomly divided into testing group (Metoprolol treatment group) and control group (regular treatment group) with 40 cases for each group.Metoprolol group therapy based on the use of conventional metoprolol tablets,an initial dose of metoprolol 12.5 mg/d,titrated to the appropriate dose based on heart rate and tolerance of the morning resting heart rate of 55 to 60 times/min that reached the target dose of metoprolol continuous medication for 12 months.Blood gas analysis were recorded before and after treatment,pulmonary function,and 6 min walk test (6MWT) and were chronic lung disease Assessment Test (CAT) Rating.The control group was administrated regular treatment while the testing group added small dose of Metoprolol with titration to an appropriate dose on this basis.12 months in a row,and assessed the end stage.Results (1) After the application of selective β receptor blockers on testing group,no statistically significant difference (P＞0.05) in the values of FEV1 in anticipation value％ (testing group:(45.45 ± 4.68) ％ vs.(43.32 ± 4.84) ％;control group:(44.23 ± 4.68) ％ vs.(42.58 ±4.24)％),PaO2(testing group:(75.92± 10.78) mmHg vs.(74.86± 11.21) mmHg;control group:(70.23 ±6.45) mmHg vs.(72.36±7.28) mmHg) and PaCO2(testing group:(46.28±8.28) mmHg vs.(47.46±10.22) mmHg);control group:(44.54 ± 8.89) mmHg vs.(42.36 ± 7.45) mmHg) before and after treatment.But the 6MWD (testing group:(287 ± 23) m vs.(384± 34) m;control group:(284 ± 25) m vs.(295 ±21) m) and COPD appraisal test(CAT) (testing group:(21±7) score vs.(17±6) score);control group:(22 ±5) score vs.(20± 6) score) had improved significantly compared with that before treatment,with significant difference(t=4.903,4.784;P＜0.05).Conclusion Selective β receptor blockers have no effect on the airway resistance of COPD patients and reduction on pulmonary function.It can also increase the exercise tolerance and enhance the living quality for improving clinical prognosis.

Objective To evaluate the efficacy of endotracheal tube (ETT) with injecting medicine for continuous airway topical anesthesia in inhibiting responses to an indwelling ETT after operation in the patients undergoing maxillofacial surgery. Methods Sixty patients of both sexes, aged 18-64 yr, weig-hing 45-75 kg, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, scheduled for elective maxillofacial surgery under general anesthesia, were divided to control group ( group C) and ETT with in-jecting medicine for continuous airway topical anesthesia group (group E) by a random number table meth-od, with 30 patents in each group. ETT was indwelled until the patients were admitted to intensive care unit (ICU) after the end of surgery, midazolam 0. 02-0. 03 mg∕kg was intravenously injected, and sufentanil was intravenously infused at a rate of 0. 02-0. 10 μg·kg-1·h-1for sedation. In group E, 2% lidocaine 2 ml was injected through the ETT with injecting medicine every 2 h to perform airway topical anesthesia. The equal volume of normal saline was injected through the ETT with injecting medicine every 2 h to maintain the Ramsay sedation score ≥2 in group C. The occurrence of hypertension, tachycardia and bucking and seda-tive requirements were recorded within 24 h after admission to ICU. The concentrations of norepinephrine and methoxyepinephrine in urine were determined by enzyme-linked immunosorbent assay at 24 h after ad- mission to ICU. Results Compared with group C, the frequency of hypertension, tachycardia and bucking were significantly decreased, the consumption of midazolam and sufentanil was reduced, and the concentra-tions of norepinephrine and methoxyepinephrine in urine were decreased in group E (P＜0. 05). Conclusion ETT with injecting medicine can markedly inhibit responses to an indwelling ETT after operation when used for continuous airway topical anesthesia in the patients undergoing maxillofacial surgery.

OBJECTIVE To investigate the improve-ment functions of flavonoid compounds on temozolomide(TMZ)-,aging-or AD model-induced dysregulation of hip-pocampal NSC lineage progression,retardancy of den-dritic spine maturation in new-born neurons,as well as impairment of hippocampal-related learning and memory.METHODS We applied 30-week-old neural stem cell(NSC)specific promoter Nestin-GFP and NestinCreERT2:Rosa26-LSL-tdTomato transgenic mice and 16-week-old AD model 5XFAD transgenic mice,together with hippo-campal microinjection(ih),endogenous fluorescence trac-ing and immunofluorescent staining.RESULTS Both fla-vonoid compound A and its functional derivative flavo-noid compound B dose-dependently improved TMZ-,aging-or AD-induced defects of hippocampal NSC lin-eage progression and the maturation of dendritic spines of newborn neurons,thereby improving hippocampus related learning and memory.CONCLUSION This paper provides a new idea and treatment strategy for the devel-opment of new flavonoids that can promote neurogene-sis for neurodegenerative diseases and aging.

Target trail emulation is an observational research method, which can use real-world data (such as observational data and historical data) to carry out research design according to the design principles of randomized controlled trials (RCT) when RCT cannot be carried out. The intervention group and the control group were classified by simulating random grouping. Finally a high-reliable conclusion similar to RCT can be obtained. This paper summarizes the basic concepts and application process of target trail emulation based on the effect of statins on the prognosis of myocardial infarction in diabetic patients to provide reference for the application of this method in real world.

Objective:To analyze the relationship between early-life famine exposure and the risk of metabolic syndrome in Chinese population.Methods:Relevant literature on the relationship between early-life famine exposure and the risk of metabolic syndrome in the Chinese population was retrieved from databases such as CNKI, Wanfang, VIP, CBM, Web of Science, and PubMed. The search was conducted from the inception of the databases up to October 2022. Two researchers independently extracted and systematically evaluated the data from the literature, and meta-analysis was performed using Stata 16.0 software. Results:A total of 12 publications met the inclusion criteria, including 71 470 study subjects. Meta-analysis results showed that early-life famine exposure increased the risk of metabolic syndrome in the Chinese population( OR=1.28, 95% CI 1.16-1.40). Subgroup analysis showed that both fetal famine exposure( OR=1.25, 95% CI 1.03-1.52) and childhood famine exposure( OR=1.29, 95% CI 1.15-1.45) increased the risk of developing metabolic syndrome compared to the non-exposed group, and this significant association was only found in the female population. Conclusion:Early-life exposure to famine may increase the risk of developing metabolic syndrome in adulthood in the Chinese population, particularly among females.
