ObjectiveTo evaluate the effects of Esmolo on the hemodynamic and tissue oxygenation of the patients with septic shock and tachycardia.MethodsSeventy four septic shock patients with tachycardia were enrolled and randomized into Esmolo-treated group and control group after early goal-directed therapy (EGDT).The patients in Esmolo group were given intravenous Esmlol to decrease the heart rate to below 110 beats per minute.Hemodynamic data and tissue oxygenation parameters,such as Heart rate (HR),Mean Artery Pressure ( MAP),Central Venous Pressure ( CVP),Cardiae Index ( CI),Stroke Volume Index ( SVI),Systemic Vascular Resistance Index (SVRI),Lactate,Centrol Venous Oxygen Saturation (SCVO2 ) were recorded before and 2,3,4 hours after the Esmolol treatment.Results Heart rate of Esmolol group was reduced at all time points after treatment,The difference of that from the control group was significant ( H R: [ 108 ± 16 ] beats/min vs.[ 132 ± 18 ] beats/min,[ 101 ± 14] beats/min vs.[ 135 ± 19 ] beats/min,[ 106 ± 21 ] beats/rin vs.[ 129 ± 14]beats/min,all P ＜ 0.01 ).Compared to the control group,Stroke Volume Index of Esmolol group was significantly increased at each time point ( SVI: [32 ± 12] ml/m2 vs.[22 ±8] ml/m2,[34 ± 14] ml/m2 vs.[21 ±6] ml/m2,[37 ± 10] ml/m2vs.[23 ±9] ml/m2,all P ＜0.05).Lactate of Esmolol group was significantly decreased at the end of the 3rd,4th hour of Esmolol treatment ( lactate: [ 1.6 ± 1.1 ] mmol/L vs.[ 2.7 ± 1.2 ]mmol/L,[ 1.3 ± 0.9 ] mmol/Lvs.[ 2.8 ± 1.4 ] mmol/L,both P ＜ 0.01.There were no significant differences in MAP,CI,SVRI,SCVO2 between the two groups at each time point ( all P ＞ 0.05 ).Conclusion Esmolol can reduce heart rate significantly,improve cardiac work and tissue perfusion in septic shock patients with tachycardia.It is a feasible and safe treatment for this kind of patients.

Objective To summary the clinical data of pediatric renal transplantation from multiple renal transplant centers in China,and analyze the factors influencing the therapeutic outcomes of pediatric renal transplantation.Methods From March 1986 to May 2010,the clinical data of 138 children who underwent renal transplantation in eight centers of renal transplantation in China were retrospectively analyzed.Results The one-year patient and graft survival rate was 99.3％ and 95.7％respectively.Acute rejection episodes occurred in 38 cases (27.5％),15 cases suffered delayed graft function (DGF),and graft functions were returned to normal in all recipients within one month.Moreover,other complications included transplant renal artery stenosis in 8 cases (5.8％),ureteral necrosis in 2 cases (1.4％),urinary fistula in 5 cases (3.6％),hypertension in 57 cases (41.3 ％),hyperlipidemia in 38 cases (27.5％),hirsutism in 32 cases (23.2％),drug-induced liver damage in 26 cases (18.8％),urinary tract infection in 25 cases (18.1％ ),gingival hyperplasia in 22 cases (15.9％),pulmonary infection in 21 cases (15.2％),bone marrow suppression in 12 patients (8.7％),herpes simplex in 10 cases (7.2％),and diabetes in 8 cases (5.8％).The body weight was increased by 4 to 13 kg and the body height was increased by 2 to 7 cm during the first year posttransplantation. Conclusion The careful perioperative management, rational use of immunosuppressive agents,strengthening the follow-up management of children and social support,and improving compliance were the key points to obtain good outcomes in pediatric renal transplantation.

Objective: To understand the vision status of primary and secondary school students in Beijing, in order to provide scientific reference for myopia prevention and control. Methods: From 2018 to 2021, a stratified cluster sampling method was used to monitor myopia among 191 293 primary and secondary school students selected from 6 urban areas and 10 suburban areas in Beijing. Myopic screening was in accordance with the "standards for children and adolescents myopic screening", and was measured by an automatic desktop computer optometer under non-cycloplegic conditions. Statistical analysis was used by Chi-square test. Results: The total myopia rate of primary and middle school students in Beijing from 2018 to 2021 were 60.7%, 57.6%, 59.2% and 59.7%, respectively. In 2018, the myopia rates of primary school students, middle school students, regular high school students and vocational high school students were 38.3%, 77.3%, 88.3% and 73.2% respectively. In 2019, they were 34.7%, 76.4%, 87.7% and 72.0%, respectively; in 2020, they were 37.5%, 76.8%, 86.8%, 74.9%; in 2021, they were 38.7%, 77.4%, 86.5% and 74.9 % respectively. Significant differences in educational stage were observed ( χ 2=7 386.07, 11 104.28, 9 850.08, 9 714.59, P <0.01). From 2018 to 2021, the overall myopia rate of girls (62.1%) was higher than that of boys (56.5%)( χ 2=613.75, P <0.01). The myopia rate of girls were higher than that of boys in each year, and significant differences in educational stage were observed, respectively( χ 2=120.47, 163.47, 168.01, 162.24, P <0.01). The overall myopia rate of urban students(63.0%) was higher than that of suburban students (56.0%)( χ 2=978.82, P <0.01). The myopia rate of urban students were higher than that of suburban students every year, and significant differences in educational stage were observed, respectively ( χ 2=86.71, 240.96, 302.56, 409.30 , P < 0.01 ). Conclusion The detection rate of myopia rate of primary and middle school students in Beijing is still high. It is necessary to strengthen the publicity and intervention of poor visual acuity in primary and middle school students, especially among urban area students, with the aim of effectively control and reduction in the myopia rate, and the improvement of student visual health.

The objective of this study was to examine the effects of electroacupuncture on the expression of ATP-binding cassette transporter A1(ABCA1),ATP-binding cassette transporter G1(ABCG1),and class B type Ⅰ scavenger receptor(SR-B Ⅰ)genes and proteins in peritoneal macrophages of atherosclerotic rabbits.The study aimed to explore the mechanism underlying the treatment of atherosclerosis(AS)with electroacupuncture.Methods Twenty-six male New Zealand rabbits were randomly divided into the negative control group(n=7)and the modeling group(n=19)using a random number table method.The negative control group rabbits were fed a regular diet,while the modeling group was induced with a combination of high-fat feed and common carotid artery balloon injury surgery to create an AS model.After successful modeling,the rabbits in the modeling group were further divided into the model group,the electroacupuncture group,and the atorvastatin group,with 6 rabbits in each group.The rabbits in the electroacupuncture group received electroacupuncture at"'Neiguan'(PC6)","'Zusanli'(ST36)",and"'Guanyuan'(ST25)"acupoints,using a density wave,a current of 1 mA,and a frequency of 4 Hz/20 Hz,once a day.The needle was retained for 20 minutes each time,and a total of 4 courses of treatment were conducted,with 6 days per course.The rabbits in the atorvastatin group were administered atorvastatin calcium tablet suspension(1 mg/kg)orally once a day,for 6 days per course,with a total of 4 courses.After the interventions,HE staining was performed to observe the morphological changes in the common carotid artery tissue of the rabbits.Peritoneal macrophages were collected from the rabbits,and the mRNA expression levels of ABCA1,ABCG1,and SR-B Ⅰ were measured using real-time fluorescence PCR.The protein expression levels of ABCA1,ABCG1,and SR-B Ⅰ were detected using Western blotting.Results The negative control group exhibited smooth intima of common carotid artery in rabbits,while the model group displayed damaged intima of common carotid artery,thickened artery walls,and the formation of atherosclerotic plaques.The electroacupuncture group and atorvastatin group showed significant improvements in wall thickening and a reduction in plaque area.Compared with the negative control group,the mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits in the model group were reduced(P＜0.01).Compared with the model group,the electroacupuncture group and atorvastatin group exhibited increased mRNA and protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in abdominal macrophages of rabbits(P＜0.01).Furthermore,the atorvastatin group demonstrated increased mRNA levels of ABCG1 and SR-B Ⅰ,as well as increased protein expressions of ABCA1,ABCG1,and SR-B Ⅰ in peritoneal macrophages of rabbits,in comparison to the electroacupuncture group(P＜0.01).Conclusion Electroacupuncture can enhance the expressions of ABCA1,ABCG1,and SR-B Ⅰ mRNA and protein in abdominal macrophages of AS rabbits,thereby promoting the process of cholesterol reverse transport.This may be one of the mechanisms underlying the effectiveness of acupuncture in the treatment of AS.

Palliative care not only embodies modern life perspectives, but also encompasses significant traditional Chinese cultural elements.The primary objective of palliative care is to alleviate patient suffering, preserve their dignity, and facilitate a peaceful passing.Traditional Chinese medicine, known for its simplicity, accessibility, affordability, and efficacy in disease prevention and treatment, adopts a holistic approach to address systemic pain through personalized treatment based on symptom differentiation.This approach aims to enhance the quality of life for terminally ill patients.To equip palliative care providers with essential clinical skills in traditional Chinese medicine, the National Center of Gerontology and Beijing Palliative Care Guidance Center collaborated with experts and scholars to develop guidelines focusing on common end-of-life symptoms.Through extensive deliberation, expert evaluation, and revisions, this guidance document was crafted as a valuable resource for palliative care practitioners, traditional Chinese medicine clinicians, and researchers in the field.

ObjectiveTo investigate the effect of 1，25（OH）₂D₃ on the level of peroxisome proliferator-activated receptor-γ （PPAR-γ） in the liver， the phenotype of hepatic macrophages， and liver inflammation in a rat model of nonalcoholic steatohepatitis （NASH）， as well as the mechanism of 1，25（OH）₂D₃ improving liver inflammation. MethodsAfter 1 week of adaptive feeding， 24 specific pathogen-free Wistar rats were randomly divided into normal group ［choline-supplemented L-amino acid-defined （CSAA） diet］， normal+1，25（OH）₂D₃ group ［CSAA diet+1，25（OH）₂D₃］， model group ［choline-deficient L-amino acid-defined diet （CDAA） diet］， and model+1，25（OH）₂D₃ group ［CDAA diet+1，25（OH）₂D₃］， with 6 rats in each group. The dose of 1，25（OH）₂D₃ was 5 μg/kg for intraperitoneal injection twice a week for 12 weeks. The serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） were measured， liver histopathology was observed， and SAF score was assessed. M1 hepatic macrophages and M2 hepatic macrophages were measured to analyze in the change in the phenotype of hepatic macrophages， and ELISA was used to measure the levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， interleukin-4 （IL-4）， and interleukin-10 （IL-10） in liver tissue， and qPCR was used to measure the mRNA level of PPAR-γ. The two-factor analysis of variance was use for comparison between groups， and the least significant difference t-test was used for further comparison； the Pearson method was used for correlation analysis. ResultsCompared with the normal group， the model rats with CDAA diet-induced NASH had significant increases in the serum levels of AST and ALT （P=0.019 and P<0.001）， the SAF score of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， and the ratio of M1 and M2 hepatic macrophages （P<0.001）， as well as a significant increase in the level of TNF-α （P<0.001） and a significant reduction in the level of IL-4 in liver tissue （P=0.025）. The 1，25（OH）₂D₃ group had significant reductions in the serum levels of ALT （P<0.001）， the SAF score of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， and the ratio of M1 and M2 hepatic macrophages （P=0.001）， the level of IL-1β （P<0.001） and a significant increase in the level of M2 hepatic macrophages （P=0.017）， the level of IL-10 （P=0.039）， the level of IL-4 （P<0.001）， the level of PPAR-γ （P=0.016）. There were significant interactions between CDAA diet-induced NASH model and 1，25（OH）₂D₃ in serum the levels of AST and ALT （P=0.007 and P=0.008）， the SAF scores of liver histopathology （P<0.001）， the level of M1 hepatic macrophages （P<0.001）， the level of M2 hepatic macrophages （P=0.008）， the ratio of M1 and M2 of hepatic macrophages （P=0.005）， the level of TNF-α （P<0.001）， the level of IL-10 （P=0.038）， the level of IL-4 （P<0.001） and the level of PPAR-γ （P=0.009）. The correlation analysis showed that PPAR-γ was negatively correlated with the ratio of M1 and M2 hepatic macrophages （r=-0.415， P=0.044） and was positively correlated with M2 hepatic macrophages （r=0.435， P=0.033）， IL-10 （r=0.433， P=0.035）， and IL-4 （r=0.532， P=0.007）. ConclusionThis study shows that 1，25（OH）₂D₃ improves liver inflammation in NASH by activating PPAR-γ to regulate the phenotypic transformation of hepatic macrophages.

Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.
