Résumé
What are the new contents of the guideline since 2010?A.Patients with primary and non-primary sclerosing cholangitis (PSC) are included in these guidelines for the diagnosis and management of cholangiocarcinoma.B.Define "related stricture" as any biliary or hepatic duct stricture accompanied by the signs or symptoms of obstructive cholestasis and/or bacterial cholangitis.C.Patients who have had an inconclusive report from MRI and cholangiopancreatography should be reexamined by high-quality MRI/cholangiopancreatography for diagnostic purposes. Endoscopic retrograde cholangiopancreatography should be avoided for the diagnosis of PSC.D. Patients with PSC and unknown inflammatory bowel disease (IBD) should undergo diagnostic colonoscopic histological sampling, with follow-up examination every five years until IBD is detected.E. PSC patients with IBD should begin colon cancer monitoring at 15 years of age.F. Individual incidence rates should be interpreted with caution when using the new clinical risk tool for PSC for risk stratification.G. All patients with PSC should be considered for clinical trials; however, if ursodeoxycholic acid (13-23 mg/kg/day) is well tolerated and after 12 months of treatment, alkaline phosphatase (γ- Glutamyltransferase in children) and/or symptoms are significantly improved, it can be considered to continue to be used.H. Endoscopic retrograde cholangiopancreatography with cholangiocytology brushing and fluorescence in situ hybridization analysis should be performed on all patients suspected of having hilar or distal cholangiocarcinoma.I.Patients with PSC and recurrent cholangitis are now included in the new unified network organ sharing policy for the end-stage liver disease model standard.J. Liver transplantation is recommended after neoadjuvant therapy for patients with unresectable hilar cholangiocarcinoma with diameter < 3 cm or combined with PSC and no intrahepatic (extrahepatic) metastases.

Objective: To describe the distribution characteristics of hypertension among adult twins in the Chinese National Twin Registry (CNTR) and to provide clues for exploring the role of genetic and environmental factors on hypertension. Methods: A total of 69 220 (34 610 pairs) of twins aged 18 and above with hypertension information were selected from CNTR registered from 2010 to 2018. Random effect models were used to describe the population and regional distribution of hypertension in twins. To estimate the heritability, the concordance rates of hypertension were calculated and compared between monozygotic twins (MZ) and dizygotic twins (DZ). Results: The age of all participants was (34.1±12.4) years. The overall self-reported prevalence of hypertension was 3.8%(2 610/69 220). Twin pairs who were older, living in urban areas, married, overweight or obese, current smokers or ex-smokers, and current drinkers or abstainers had a higher self-reported prevalence of hypertension (P<0.05). Analysis within the same-sex twin pairs found that the concordance rate of hypertension was 43.2% in MZ and 27.0% in DZ, and the difference was statistically significant (P<0.001). The heritability of hypertension was 22.1% (95%CI: 16.3%- 28.0%). Stratified by gender, age, and region, the concordance rate of hypertension in MZ was still higher than that in DZ. The heritability of hypertension was higher in female participants. Conclusions: There were differences in the distribution of hypertension among twins with different demographic and regional characteristics. It is indicated that genetic factors play a crucial role in hypertension in different genders, ages, and regions, while the magnitude of genetic effects may vary.

Objective: To describe the distribution characteristics of hyperlipidemia in adult twins in the Chinese National Twin Registry (CNTR) and explore the effect of genetic and environmental factors on hyperlipidemia. Methods: Twins recruited from the CNTR in 11 project areas across China were included in the study. A total of 69 130 (34 565 pairs) of adult twins with complete information on hyperlipidemia were selected for analysis. The random effect model was used to characterize the population and regional distribution of hyperlipidemia among twins. The concordance rates of hyperlipidemia were calculated in monozygotic twins (MZ) and dizygotic twins (DZ), respectively, to estimate the heritability. Results: The age of all participants was (34.2±12.4) years. This study's prevalence of hyperlipidemia was 1.3% (895/69 130). Twin pairs who were men, older, living in urban areas, married,had junior college degree or above, overweight, obese, insufficient physical activity, current smokers, ex-smokers, current drinkers, and ex-drinkers had a higher prevalence of hyperlipidemia (P<0.05). In within-pair analysis, the concordance rate of hyperlipidemia was 29.1% (118/405) in MZ and 18.1% (57/315) in DZ, and the difference was statistically significant (P<0.05). Stratified by gender, age, and region, the concordance rate of hyperlipidemia in MZ was still higher than that in DZ. Further, in within-same-sex twin pair analyses, the heritability of hyperlipidemia was 13.04% (95%CI: 2.61%-23.47%) in the northern group and 18.59% (95%CI: 4.43%-32.74%) in the female group, respectively. Conclusions: Adult twins were included in this study and were found to have a lower prevalence of hyperlipidemia than in the general population study, with population and regional differences. Genetic factors influence hyperlipidemia, but the genetic effect may vary with gender and area.

Objective: To investigate the epidemiology and hospitalization costs of pediatric community-acquired pneumonia (CAP) in Shanghai. Methods: A retrospective case summary was conducted on 63 614 hospitalized children with CAP in 59 public hospitals in Shanghai from January 2018 to December 2020. These children's medical records, including their basic information, diagnosis, procedures, and costs, were extracted. According to the medical institutions they were admitted, the patients were divided into the children's hospital group, the tertiary general hospital group and the secondary hospital group; according to the age, they were divided into <1 year old group, 1-<3 years old group, 3-<6 years old group, 6-<12 years old group and 12-18 years old group; according to the CAP severity, they were divided into severe pneumonia group and non-severe pneumonia group; according to whether an operation was conducted, the patients were divided into the operation group and the non-operation group. The epidemiological characteristics and hospitalization costs were compared among the groups. The χ2 test or Wilcoxon rank sum test was used for the comparisons between two groups as appropriate, and the Kruskal-Wallis H test was conducted for comparisons among multiple groups. Results: A total of 63 614 hospitalized children with CAP were enrolled, including 34 243 males and 29 371 females. Their visiting age was 4 (2, 6) years. The length of stay was 6 (5, 8) days. There were 17 974 cases(28.3%) in the secondary hospital group, 35 331 cases (55.5%) in the tertiary general hospital group and 10 309 cases (16.2%) in the children's hospital group. Compared with the hospitalizations cases in 2018 (27 943), the cases in 2019 (29 009) increased by 3.8% (1 066/27 943), while sharply declined by 76.2% (21 281/27 943) in 2020 (6 662). There were significant differences in the proportion of patients from other provinces and severe pneumonia cases, and the hospitalization costs among the children's hospital, secondary hospital and tertiary general hospital (7 146 cases(69.3%) vs. 2 202 cases (12.3%) vs. 9 598 cases (27.2%), 6 929 cases (67.2%) vs. 2 270 cases (12.6%) vs. 9 397 cases (26.6%), 8 304 (6 261, 11 219) vs. 1 882 (1 304, 2 796) vs. 3 195 (2 364, 4 352) CNY, χ2=10 462.50, 9 702.26, 28 037.23, all P<0.001). The annual total hospitalization costs of pediatric CAP from 2018 to 2020 were 110 million CNY, 130 million CNY and 40 million CNY, respectively. And the cost for each hospitalization increased year by year, which was 2 940 (1 939, 4 438), 3 215 (2 126, 5 011) and 3 673 (2 274, 6 975) CNY, respectively. There were also significant differences in the hospitalization expenses in the different age groups of <1 year old, 1-<3 years old, 3-<6 years old, 6-<12 years old and 12-18 years old (5 941 (2 787, 9 247) vs. 2 793 (1 803, 4 336) vs. 3 013 (2 070, 4 329) vs. 3 473 (2 400, 5 097) vs. 4 290 (2 837, 7 314) CNY, χ2=3 462.39, P<0.001). The hospitalization cost of severe pneumonia was significantly higher than that of non-severe cases (5 076 (3 250, 8 364) vs. 2 685 (1 780, 3 843) CNY, Z=109.77, P<0.001). The cost of patients who received operation was significantly higher than that of whom did not (10 040 (4 583, 14 308) vs. 3 083 (2 025, 4 747) CNY, Z=44.46, P<0.001). Conclusions: The number of children hospitalized with CAP in Shanghai decreased significantly in 2020 was significantly lower than that in 2018 and 2019.The proportion of patients from other provinces and with severe pneumonia are mainly admitted in children's hospitals. Hospitalization costs are higher in children's hospitals, and also for children younger than 1 year old, severe cases and patients undergoing operations.

Objective: To explore the associations between blood pressure trajectories during pregnancy and risk of future pre-eclampsia in a large cohort enrolling pregnant women at gestational age of ~12 weeks from community hospitals in Tianjin. Latent class growth modeling (LCGM) was used to model the blood pressure trajectories. Methods: This was a large prospective cohort study. The study enrolled pregnant women of ~12 weeks of gestation in 19 community hospitals in Tianjin from November 1, 2016 to May 30, 2018. We obtained related information during 5 antepartum examinations before gestational week 28, i.e., week 12, week 16, week 20, week 24 and week 28. LCGM was used to model longitudinal systolic (SBP) and diastolic blood pressure (DBP) trajectories. For the association study, the predictors were set as SBP and DBP trajectory membership (built separately), the outcome was defined as the occurrence of preeclampsia after 28 weeks of gestation. Results: A total of 5 809 cases with known pregnant outcomes were documented. After excluding 249 cases per exclusion criteria, 5 560 cases with singleton pregnancy were included for final analysis. There were 128 cases preeclampsia and 106 cases gestational hypertension in this cohort. Univariate logistic regression and multivariate logistic regression showed the higher baseline SBP level and DBP level were related with increased risk of preeclampsia. Four distinctive SBP trajectories and DBP trajectories from 12 weeks to 28 weeks of gestation were identified by LCGM. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for SBP latent classification trajectory_ 4 was 4.023 (95%CI: 2.368 to 6.835, P<0.001), and the OR for SBP latent classification trajectory_3 was 1.854 (95%CI: 1.223 to 2.811, P=0.004). Logistic regression showed that: using the DBP latent classification trajectory_1 as the reference group, the OR for DBP latent classification trajectory_4 was 4.100 (95%CI: 2.571 to 6.538, P<0.001), and 2.632 (95%CI: 1.570 to 4.414, P<0.001) for DBP latent classification trajectory_2. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for DBP_traj_4 was 2.527 (95%CI: 1.534 to 4.162, P<0.001), and the OR for DBP_traj_3 was 1.297 (95%CI: 0.790 to 2.128, P=0.303), and 2.238 (95%CI: 1.328 to 3.772, P=0.002) for DBP_traj_2. Therefore, BP trajectories from 12 weeks to 28 weeks identified by LCGM served as novel risk factors that independently associated with the occurrence of preeclampsia. Receiver operating characteristic (ROC) curve analysis showed incremental diagnostic performance by combing baseline blood pressure levels with blood pressure trajectories. Conclusion: By applying LCGM, we for the first time identified distinctive BP trajectories from gestational week 12 to 28, which can independently predict the development of preeclampsia after 28 weeks of gestation.

Aim To investigate the anti-tumor effect of celastrol(CEL)on colorectal cancer and the possible targets/mechanisms. Methods The cytotoxic activities of CEL were evaluated against A549, HCT-116, HepG2 by CCK-8 method. Western blotting was used to detect the expression level of STAT3 and its upstream and downstream proteins(JAK2, Survivin, MCL-1)in HCT-116 cells before and after CEL treatment Flow cytometry was applied to assess CEL's apoptosis and cell-cycle arrest effect in HCT-116 cells. SPR detection and molecular docking analysis were performed to further assess the binding ability between CEL and STAT3 protein. Lastly, human colorectal cancer organoid culture was constructed to verify the anti-tumor effect of CEL. Results CEL showed significant cytotoxicity to A549(IC50 = 2.37±0.02 μmol·L-1), HCT-116(IC50 = 1.40±0.21 μmol·L-1)and HepG2(IC50 = 2.52±0.02 μmol·L-1). Additionally, CEL could effectively decrease the level of p-STAT3 and the downstream gene expression of STAT3(Survivin and MCL-1)in a concentration-dependent manner; however, CEL did not affect the total level of STAT3 and upstream kinases JAK2. Moreover, CEL could induce apoptosis of HCT-116 cells concentration-dependently and arrest the cell cycle. According to the SPR analysis, CEL showed a strong binding affinity with the KD value(the equilibrium dissociation constant)of 60.38 μmol·L-1. Molecular docking analysis also suggested that CEL bound to the SH2 domain of STAT3. Lastly, CEL showed much better activity than the positive drug oxaliplatin(L-OHP)on all the colorectal cancer organoids. Conclusions CEL shows a significant anti-colorectal cancer effect, potentially caused by a direct target inhibiting STAT3, inducing apoptosis, and blocking the cell cycle.
Résumé
Panacis Quinquefolii Radix is the dry root of Panax quinquefolium, which is a perennial plant of Araliaceae. The plant has a long growth cycle and serious growth barrier problem, which leads to the use of pesticides. As a result, the pesticide residues in Panacis Quinquefolii Radix are arousing great concern. This paper reviews the research findings on the investigation, detection methods, content analysis and risk assessment of pesticide residues in Panacis Quinquefolii Radix since 1993, and compares the pesticide residue limit standards of different countries and regions. The pesticide residues in Panacis Quinquefolii Radix have been changing from organochlorines with high toxicity to triazines and triazoles with low toxicity. The pesticide residues are generally low, while the pollution of pentachloronitrobenzene and other pesticides still exist. The detection method has evolved from chromatography to chromatography-mass spectrometry. There are no reports of health risks caused by pesticide residues of Panacis Quinquefolii Radix. Pesticide residue is a major factor restricting the sound development of Panacis Quinquefolii Radix industry in China. Therefore, we suggest to improve the registration of pesticides applied to the plant, popularize mature ecological planting mode and supporting technology, and strengthen the research on the risk assessment and limit standard of pesticide residue in Panacis Quinquefolii Radix.

Lonicera Japonica Flos is the dried bud or nascent flower of Lonicera japonica(Caprifoliaceae). The plant suffers from various diseases and pests in the growth period and thus pesticides are often used. As a result, the resultant pesticide residues in Lonicera Japonica Flos have aroused great concern. This review summarized the investigation, detection methods, content analysis, and risk assessment of pesticide residues in Lonicera Japonica Flos since 1996, and compared the maximum residue limits among different countries and regions. The results showed that the pesticide residues were detected in Lonicera Japonica Flos from different production areas, and only some exceeded the limits. The residual pesticides have changed from organochlorines to new types such as tebuconazole and nitenpyram. The detection method has upgraded from chromatography to chromatography-mass spectrometry. Most pesticide residues will not cause health risks, except carbofuran. Pesticide residues limit the development of Lonicera Japonica Flos industry in China. In practice, we should improve the drug registration of Lonicera Japonica Flos, promote ecological prevention and control technology, and formulate and promote pesticide residue limit standard of Lonicera Japonica Flos.

OBJECTIVE@#To investigate the correlation between serum vitamin D level and clinical outcomes after repair of rotator cuff tears.@*METHODS@#A total 122 patients who met the inclusion criteria and were followed up for 12 months from March 2018 to March 2020 were analyzed retrospectively, including 50 males and 72 females with an average age of(62.10±8.39) years old (ranged, 34 to 82 years old). All patients were divided into deficiency group(vitamin D<20 μg/L) and control group(vitamin D≥20 μg/L), including 62 cases in the deficiency group, with vitamin D (14.80±3.18) μg/L;60 cases in the control group, with vitamin D(25.17±5.64) μg/L. The two groups were compared in terms of age, gender, body mass index(BMI), tear size, degree of retraction, degree of fatty infiltration, injury factors, postoperative pain VAS score, postoperative shoulder joint function score, and re-tear rate. The age of all patients was divided into two categories:<60 years old and ≥60 years old;BMI was divided into <24 kg/m2 and ≥ 24 kg/m2;tear size was divided into ≤3 cm and >3 cm;retraction degree was divided into ≤2 cm and >2 cm;fat infiltration was divided into ≤2 grade and >2 grade;and the course of the disease was ≤3 months and >3 months. The correlation between Sugaya re-tear type and the variables listed above were analyzed and calculated.@*RESULTS@#There were no major complications such as joint infection, anchor withdrawal and revision surgery in any of the 122 patients who were followed up on. There were no statistical differences in age, gender, injury factor, BMI, tear size, degree of retraction, degree of fatty infiltration, and duration of disease between the two groups (P>0.05). The Constant-Murley scores, UCLA scores, and ASES scores of the two groups all improved considerably after surgery(P<0.05);however, there was no statistical differences in the postoperative shoulder function scores between the two groups (P>0.05). There was significant difference in VAS between the two groups 1 month and 3 months after operation, with vitamin D deficiency group scoring higher, and there was no significant differences 6 and 12 months after operation. Tear size(>3 cm), degree of retraction(>2 cm), degree of fatty infiltration(>2 degree) were all shown to be the independent risk factors for retear after surgery by Logistic regression analysis(P<0.05). The comparison between the two groups of patients using a 2×5 row list showed that the Sugaya classification of rotator cuff re-tear(grade Ⅰto Ⅴ) between the vitamin D deficiency group and the control group was statistically different(t=14.228, P=0.007). It was discovered that the Sugaya classification after surgery was statistically different between the two groups.@*CONCLUSION@#Vitamin D deficiency is not correlated with clinical function scores and re-tear rate, however it is associated with the early postoperative pain (1 and 3 months) and the quality of rotator cuff healing (Sugaya classification) after surgery.

Objective: To describe the distribution characteristics of type 2 diabetes in twins in Chinese National Twin Registry (CNTR), provide clues and evidence for revealing the influence of genetic and environmental factors for type 2 diabetes. Methods: Of all twins registered in the CNTR during 2010-2018, a total 18 855 twin pairs aged ≥30 years with complete registration information were included in the analysis. The random effect model was used to describe the population and area distribution characteristics and concordance of type 2 diabetes in twin pairs. Results: The mean age of the subjects was (42.8±10.2) years, the study subjects included 10 339 monozygotic (MZ) twin pairs and 8 516 dizygotic (DZ) twin pairs. The self-reported prevalence rate of type 2 diabetes was 2.2% in total population and there was no sighificant difference between MZ and DZ. Intra-twin pairs analysis showed that the concordance rate of type 2 diabetes was 38.2% in MZ twin pairs, and 16.0% in DZ twin pairs, the difference was statistically significant (P<0.001). The concordance rate of type 2 diabetes in MZ twin parts was higher than that in DZ twin pairs in both men and women, in different age groups and in different areas (P<0.05). Further stratified analysis showed that in northern China, only MZ twin pairs less than 60 years old were found to have a higher concordance rate of type 2 diabetes compared with DZ twin pairs (P<0.05). In southern China, the co-prevalence rate in male MZ twin pairs aged ≥60 years was still higher than that in DZ twin pairs (P<0.05). Conclusion: The twin pairs in this study had a lower self-reported prevalence of type 2 diabetes than the general population. The study results suggested that genetic factors play a role in type 2 diabetes prevalence in both men and women, in different age groups and in different areas, however, the effect might vary.

Objective: To describe the distribution characteristics of coronary heart disease in adult twins recruited from Chinese Twin Registry (CNTR), and provide clues and evidence for the effect of genetic and environmental influences on coronary heart disease. Methods: By using the data of CNTR during 2010-2018, a total of 34 583 twin pairs aged ≥18 years who completed questionnaire survey and had related information were included in the current study to analyze the population and area distribution characteristics of coronary heart disease. Random effect models were used to compare the differences between groups. The concordane rate of coronary heart disease were calculated respectively in monozygotic (MZ) twin pairs and dizygotic (DZ) twin pairs to estimate the heritability. Results: The twin pairs included in this analysis were aged (34.2±12.4) years. The overall prevalence rate of coronary heart disease in twin pairs was 0.7%. Twin pairs who were women, older, obese and lived in northern China had higher prevalence of coronary heart disease (P<0.05). Intra-pair analysis in the same-sex twin pairs found that the concordane rate of coronary heart disease was higher in MZ twin pairs (25.3%) than in DZ twins (7.4%), and the difference was statistically significant (P<0.001). The overall heritability of coronary heart disease was 19.3% (95%CI: 11.8%-26.8%). Stratified by gender, age and area, the concordane rate was still higher in MZ twin pairs than in DZ pairs. Participants who were women, aged 18-30 years or ≥60 years and lived in northern China had a higher heritability of coronary heart disease. Conclusion: The distribution of coronary heart disease in twin pairs differed in populations and areas. The prevalence of coronary heart disease was affected by genetic factors, but the effect varied with age, gender and area.

Objective:To investigate the changes and clinical significance of plasma S100A1 protein, nuclear factor-κB p65 (NF-κB p65) and interleukin-6 (IL-6) levels in patients with acute ischemic cerebrovascular diseases.Methods:A total of 141 patients with acute ischemic cerebral infarction (AICI; AICI group) and 20 patients with transient ischemic attack (TIA; TIA group) who received treatment in Northern Jiangsu People's Hospital from April to November 2020 were included in this study. According to the volume of cerebral infarct, the AICI group was subdivided into small-volume cerebral infarct (SCI group, n = 78), moderate-volume cerebral infarct (MCI group, n = 32) and large-volume cerebral infract (LCI group, n = 31) groups. An additional 31 healthy controls who concurrently received physical examination were included as controls (HC group). S100A1, NF-κB p65, and IL-6 levels were compared between AICI, TIA and HC groups and between SCI, MCI and LCI groups. S100A1, NF-κB p65, and IL-6 levels were correlated with the National Institutes of Health Stroke Scale score and the volume of cerebral infarct. The receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of S100A1, NF-κB p65, and IL-6 levels for AICI. Results:S100A1, NF-κB p65, and IL-6 levels in the AICI group were (230.96 ± 39.37) ng/L, (3.99 ± 0.65) mg/L, (13.32 ± 1.57) ng/L, respectively, which were significantly higher than (185.85 ± 43.24) ng/L, (3.58 ± 0.74) mg/L, (11.61 ± 1.67) ng/L in the TIA group ( t = 4.95, 2.39, 4.14, all P < 0.05) and (181.47 ± 27.39) ng/L, (3.51 ± 0.99) mg/L, (11.42 ± 2.34) ng/L in the HC group ( t = 6.54, 3.32, 5.55, all P < 0.05). There were no significant differences in S100A1, NF-κB p65, and IL-6 levels between TIA and HC groups (all P > 0.05). S100A1, NF-κB p65, and IL-6 levels in the LCI group were (254.25 ± 37.07) ng/L, (4.41 ± 0.45) mg/L, and (14.00 ± 1.40) ng/L, respectively, which were significantly higher than (225.42 ± 30.92) ng/L, (3.85 ± 0.64) mg/L, (12.77 ± 1.31) ng/L in the MCI group ( t = 3.04, 3.60, 3.20, all P < 0.05) and (223.98 ± 40.21) ng/L, (3.88 ± 0.66) mg/L, (13.27 ± 1.65) ng/L in the SCI group ( t = 3.79, 4.01, 2.25, all P < 0.05). There were no significant differences in S100A1, NF-κB p65, and IL-6 levels between MCI and SCI groups (all P > 0.05). S100A1 and NF-κB p65 levels in patients with AICI were positively correlated with the volume of cerebral infarct ( r = 0.24, 0.27, both P < 0.05). S100A1 and IL-6 levels in patients with AICI were positively correlated with the National Institutes of Health Stroke Scale score ( r = 0.24, 0.28, both P < 0.05). The areas under the curves plotting S100A1, NF-κB p65, and IL-6 levels against AICI diagnosis were 0.818, 0.667 and 0.754, respectively. The optimal cutoff values were 181.03, 3.50 and 10.79, respectively. The corresponding sensitivities were 95.0%, 76.6% and 97.2%, respectively, and the specificities were 37.3%, 45.1% and 49.0%, respectively. Conclusion:Increased S100A1, NF-κB p65, and IL-6 levels in patients with AICI are closely related to the severity of AICI.
Résumé
BACKGROUND@#Despite the recommendation of inhaled corticosteroids (ICSs) plus long-acting beta 2-agonist (LABA) and leukotriene receptor antagonist (LTRA) or ICS/LTRA as stepwise approaches in asthmatic children, there is a lack of published systematic review comparing the efficacy and safety of the two therapies in children and adolescents aged 4 to 18 years. This study aimed to compare the safety and efficacy of salmeterol/fluticasone (SFC) vs. montelukast (MON), or combination of montelukast and fluticasone (MFC) in children and adolescents aged 4 to 18 years with bronchial asthma.@*METHODS@#A systematic search was conducted in MEDLINE, EMBASE, the Cochrane Library, China BioMedical Literature Database, Chinese National Knowledge Infrastructure, VIP Database for Chinese Technical Periodical, and Wanfang for randomized controlled trials (RCTs) published from inception to May 24, 2021. Interventions are as follows: SFC vs. MON, or combination of MFC, with no limitation of dosage or duration. Primary and secondary outcome measures were as follows: the primary outcome of interest was the risk of asthma exacerbation. Secondary outcomes included risk of hospitalization, pulmonary function, asthma control level, quality of life, and adverse events (AEs). A random-effects (I2 ≥ 50%) or fixed-effects model (I2 < 50%) was used to calculate pooled effect estimates, comparing the outcomes between the intervention and control groups where feasible.@*RESULTS@#Of the 1006 articles identified, 21 studies met the inclusion criteria with 2643 individuals; two were at low risk of bias. As no primary outcomes were similar after an identical treatment duration in the included studies, meta-analysis could not be performed. However, more studies favored SFC, instead of MON, owing to a lower risk of asthma exacerbation in the SFC group. As for secondary outcome, SFC showed a significant improvement of peak expiratory flow (PEF)%pred after 4 weeks compared with MFC (mean difference [MD]: 5.45; 95% confidence interval [CI]: 1.57-9.34; I2 = 95%; P = 0.006). As for asthma control level, SFC also showed a higher full-controlled level (risk ratio [RR]: 1.51; 95% CI: 1.24-1.85; I2 = 0; P < 0.001) and higher childhood asthma control test score after 4 weeks of treatment (MD: 2.30; 95% CI: 1.39-3.21; I2 = 72%; P < 0.001) compared with MFC.@*CONCLUSIONS@#SFC may be more effective than MFC for the treatment of asthma in children and adolescents, especially in improving asthma control level. However, there is insufficient evidence to make firm conclusive statements on the use of SFC or MON in children and adolescents aged 4 to 18 years with asthma. Further research is needed, particularly a combination of good-quality long-term prospective studies and well-designed RCTs.@*PROSPERO REGISTRATION NUMBER@#CRD42019133156.

Regeneration of injured peripheral nerves is an extremely complex process. Nogo-A (neurite outgrowth inhibitor-A) inhibits axonal regeneration by interacting with Nogo receptor in the myelin sheath of the central nervous system (CNS). The aim of this study was to investigate the effects of Nogo-A and its receptor on the repair of sciatic nerve injury in rats. Sprague-Dawley rats (n=96) were randomly divided into 4 groups: control group (control), sciatic nerve transection group (model), immediate repair group (immediate repair), and delayed repair group (delayed repair). The rats were euthanized 1 week and 6 weeks after operation. The injured end tissues of the spinal cord and sciatic nerve were obtained. The protein expressions of Nogo-A and Nogo-66 receptor (NgR) were detected by immunohistochemistry. The protein expressions of Nogo-A, NgR, and Ras homolog family member A (RhoA) were detected by western blot. At 1 week after operation, the pathological changes in the immediate repaired group were less, and the protein expressions of Nogo-A, NgR, and RhoA in the spinal cord and sciatic nerve tissues were decreased (P<0.05) compared with the model group. After 6 weeks, the pathological changes in the immediate repair group and the delayed repair group were alleviated and the protein expressions decreased (P<0.05). The situation of the immediate repair group was better than that of the delayed repair group. Our data suggest that the expression of Nogo-A and its receptor increased after sciatic nerve injury, indicating that Nogo-A and its receptor play an inhibitory role in the repair process of sciatic nerve injury in rats.

SUMMARY OBJECTIVE In this study, we aimed to investigate the role of COL6A3 on cell motility and the PI3K/AKT signaling pathway in osteosarcoma. METHODS The relative expression of COL6A3 was achieved from a GEO dataset in osteosarcoma tissue. siRNA technology was applied to decrease the COL6A3 expression in cells, and cell counting kit-8 (CCK-8) assay and colony formation analysis were used to examine the cell proliferation potential. Knockdown COL6A3 made the proliferation and colony formation abilities worse than the COL6A3 without interference. Likewise, in contrast to the si-con group, cell invasion and migration were inhibited in the si-COL6A3 group. Moreover, the western blot results suggested that the PI3K/AKT signaling pathway was manipulated by measuring the protein expression of the PI3K/AKT pathway-related markers, due to the COL6A3 inhibition. CONCLUSION COL6A3 plays a crucial role in modulating various aspects of the progression of osteosarcoma, which would provide a potentially effective treatment for osteosarcoma.
RESUMO OBJETIVO Neste estudo, investigamos a função do COL6A3 na mobilidade celular e na via PI3K/AKT em osteossarcomas. METODOLOGIA A expressão relativa do COL6A3 foi obtida a partir de dados GEO em tecidos de osteossarcoma. O RNA de interferência (siRNA) foi utilizado para reduzir a expressão do COL6A3 nas células, e o teste de contagem de células kit-8 (CCK-8) e a análise de formação de colônias foram realizados para examinar o potencial de proliferação celular. Além disso, o Transwell comprovou os efeitos do si-COL6A3 na invasão celular e migração em células de osteossarcoma. Para medir os níveis de expressão das proteínas e mRNAs, utilizamos transcriptase reversa quantitativa (qRT-PCR) e western blot. RESULTADOS O COL6A3 foi regulado nos tecidos e células do osteossarcoma quando comparado com o controle normal. A redução de COL6A3 reduziu a proliferação e a capacidades de formação de colônias em relação ao COL6A3 sem interferência. Do Mesmo modo, ao contrário do observado no grupo si-con, a invasão e migração celular foram inibidas no grupo si-COL6A3. Além disso, o resultado do western blot sugere que a via PI3K/AKT foi manipulada, medindo a expressão proteica dos marcadores relacionados à PI3K/AKT, devido à inibição do COL6A3. CONCLUSÃO O COL6A3 desempenha um papel crucial na modulação de vários aspectos da progressão do osteossarcoma, o que pode representar um possível tratamento eficaz para a doença.

Objective@#To explore the intervention effect of health education combined with aerobic exercise on adolescent depression,and to provide a reference for depression prevention of adolescents.@*Methods@#A total of 84 adolescent patients with depression in Wuhan Mental Health Center were selected by convenient sampling method. They were divided into two groups according to the order of patients visits (n=42). The control group received routine health education. The experimental group received group health education of emotional intelligence, and cooperated with moderate intensity aerobic exercise. The changes of depression, emotional intelligence and serotonin (5-HT), cortisol and norepinephrine (NE) levels before and after intervention were compared between the two groups.@*Results@#Before intervention, there was no significant difference in scores of Hamilton Depression Scale (HAMD) and Social Disability Screening Schedule (SDSS) between the two groups (t=0.62,1.02,P>0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those before intervention (t=9.62, 10.05, P<0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those in the control group (t=-6.95,-7.32,P<0.05). The scores and total scores of emotional perception, self-management and other management in the experimental group after intervention were significantly higher than those before intervention (t=6.54, 7.21, 5.33 ,6.60, P<0.05). The scores of emotion perception, self-management, others’ management and total scores in the experimental group were significantly higher than those in the control group(P<0.05). compared with before intervention, the levels of 5-HT and NE in the experimental group after intervention were significantly higher, the levels of cortisol were significantly lower (t=4.62, 5.36,-16.54, P<0.05),and the level of 5-HT and NE in the experimental group was significantly higher than that in the control group, and the level of cortisol was significantly lower than that in the control group (t=15.25,8.74,-26.54,P<0.05).@*Conclusion@#The implementation of emotional intelligence group health education and aerobic exercise can effectively reduce the level of 5-HT, improve the level of cortisol, enhance the emotional intelligence of adolescents with depression, and alleviate their depressive mood.
