The correlation between serum Klotho levels and frailty in elderly people / 中华老年医学杂志

Objective:To examine the correlation between serum Klotho levels and frailty in elderly people.Methods:In this cross-sectional study, 150 community-dwelling elderly people aged 65 years and over were enrolled.Subjects were divided into a frail(n=50, 33.3%), a pre-frail(n=47, 31.3%)and a non-frail(n=53, 35.3%)group based on the Fried phenotype.General participant data, routine laboratory test results, short physical performance battery(SPPB)results and human body composition data were collected.Serum Klotho protein levels were measured by an enzyme-linked immunosorbent assay.The relationship between serum Klotho protein levels and frailty was analyzed by using Spearmen's correlation analysis and Logistic regression analysis.Results:Klotho protein levels were lower in the frail group than in the non-frail group( P=0.001), whereas differences between the frail group and the pre-frail group and between the pre-frail group and the non-frail group were not statistically significant(all P>0.05).When Klotho protein levels were classified into four quartiles, i.e., Q 1, Q 2, Q 3, and Q 4, using three cut-off vales(2.28, 3.52, and 5.09 mg/L), the prevalences of frailty were 51.4%(19/37), 39.5%(15/38), 24.3%(9/37)and 18.4%(7/38), respectively.The prevalence of frailty decreased with increasing Klotho protein levels( χ2=11.204, P=0.011).Spearman correlation analysis showed that the Klotho protein level was negatively correlated with frailty( r=-0.310, P<0.001).Multivariate Logistic regression analysis results showed that age( OR=1.109, 95% CI: 1.011-1.217, P=0.028)and sarcopenia( OR=6.511, 95% CI: 1.279-33.147, P=0.024)were risk factors for frailty, while walking( OR=0.104, 95% CI: 0.033-0.326, P<0.001), a high SPPB score( OR=0.780, 95% CI: 0.627-0.970, P=0.026), and a high Klotho protein level( OR=0.752, 95% CI: 0.581-0.974, P=0.031)were protective factors against frailty. Conclusions:The serum Klotho protein level may be used as a parameter for the assessment of frailty.It is negatively correlated with frailty, suggesting that elderly people with low serum Klotho protein levels are at high risk of developing frailty.

Regulatory effect of caveolin-1 in liver diseases / 临床肝胆病杂志

Caveolin-1 （CAV1） is a structural protein of caveolae on the plasma membrane and is an important regulatory factor for liver function. CAV1 regulates hepatic lipid deposition， lipid and glucose metabolism， mitochondrial function， and hepatocyte proliferation through various molecular pathways. Therefore， CAV1 plays a crucial role in maintaining liver physiology during the metabolic regulatory processes such as hepatic steatosis and hepatocyte proliferation. Furthermore， CAV1 is also involved in the development and progression of different types of liver injury， hepatitis， and liver cirrhosis. This article reviews the role of CAV1 in liver-related diseases and its mechanism in the regulation of liver macrophages， so as to provide a theoretical basis for targeting CAV1 in the treatment of liver-related diseases.

Quality evaluation of Indigo Naturalis based on multi-component quantification combined with chemometrics / 中国药房

OBJECTIVE To evaluate the quality of Indigo Naturalis， and to provide reference for the quality control of Indigo Naturalis. METHODS UPLC-MS/MS method was used to determine the contents of 6 indole alkaloids （indigo， indirubin， isatin， tryptanthrin， indole and indole-3-carboxaldehyde） in Indigo Naturalis from different origins. Cluster analysis， principal component analysis and partial least squares-discriminant analysis （PLS-DA） were used to evaluate the quality of Indigo Naturalis from different origins. RESULTS The contents of indigo， indirubin， isatin， tryptanthrin， indole and indole-3-carboxaldehyde in Indigo Naturalis from different origins were 20 320.83-26 585.01， 1 327.69-3 102.25， 141.69-894.50， 2.17-5.27， 2.14-5.93 and 1.69-4.34 μg/g， respectively. The Indigo Naturalis from different areas were clustered into two categories by cluster analysis. Samples S1， S2， S4， S6， S7， S9 and S10 were clustered into category Ⅰ， and samples S3， S5， S8， S11 and S12 were clustered into category Ⅱ. Indigo Naturalis from different origins was evaluated with 3 principal components. The results showed that category Ⅰ sample scored higher and had better quality， while category Ⅱ sample scored lower and had worse quality. PLS-DA showed that indigo， indirubin， tryptanthrin and isatin were the main substances that reflected the quality difference of Indigo Naturalis. CONCLUSIONS The quality of Indigo Naturalis from different origins is different， and the quality of Indigo Naturalis of different batches from the same area is not stable. The quality evaluation method of Indigo Naturalis established in this paper is stable and reliable， which can provide a basis for the quality control of Indigo Naturalis.

CT parameter changes and imaging analysis of each cerebral lobe in patients with monophasic depression / 中国基层医药

Objective:To analyze the imaging changes of patients with monophasic depression based on the changes in CT parameters of each cerebral lobe.Methods:A total of 100 patients with monophasic depression who received treatment in Department of Radiology, Shaoxing 7 th People's Hospital between June 2019 and June 2021 were included in the observation group. An additional 100 healthy individuals who concurrently received physical examination were included in the control group. CT scan of the brain was performed in all participants. CT value of each cerebral lobe was compared between the two groups. Results:CT values of the left frontal lobe and left temporal lobe in the observation group were (40.88 ± 2.01) HU and (40.21 ± 3.01) HU, respectively, which were significantly lower than those in the control group ( tleft frontal lobe = 2.94, P = 0.004; tleft temporal lobe = 3.29, P = 0.001). CT values of the right frontal lobe and right temporal lobe in the observation group were (40.09 ± 2.52) HU and (44.93 ± 3.03) HU, respectively. There were no significant differences in CT values of the right frontal lobe and right temporal lobe between the two groups ( tright frontal lobe = 1.89, P = 0.060; tright temporal lobe = 1.89, P = 0.060). There were no significant differences in CT values of the left and right occipital lobes and the left and right parietal lobes between the two groups (all P > 0.05). One-way analysis of variance revealed that the CT values of the left and right frontal lobes were negatively correlated with age (-0.441, -0.211) and course of disease (-0.445, -0.191) (both P < 0.05); the CT values of the left and right frontal lobes were not significantly correlated with 24-item Hamilton Depression Rating Scale score and the number of attacks (all P > 0.05). The CT values of the left and right temporal lobes (-0.207, -0.213), the left and right occipital lobes (-0.185, -0.195) and the left and right parietal lobes (-0.185, -0.180) were negatively correlated with age (all P < 0.05). The CT values of the left and right temporal lobes, the left and right occipital lobes, and the left and right parietal lobes were not significantly correlated with course of disease, 24-item Hamilton Depression Rating Scale score, and the number of attacks (all P > 0.05). Conclusion:The left and right frontal lobe and the left temporal lobe are atrophic in patients with monophasic depression. The degree of atrophy is closely related to the course of disease. Therefore, these findings can be used as a reference for imaging diagnosis of degenerative diseases of the central nervous system.

Effects of overall planning on staff burnout and group blood donation errors / 中国输血杂志

【Objective】 To analyze the causes of staff burnout and various errors during group blood donation in blood centers, and to explore the significance of overall planning to improve above problems. 【Methods】 Various errors occurred during group blood donation from January 2016 to December 2020 in a blood center were selected as the research object. Job burnout related survey data including emotional exhaustion (MBI-EE), work attitude (MBI-DP), sense of achievement (MBI-PA) etc. were collected. The influence of six variables, including blood collection quantity, staff, order control, plan compliance, overload blood collection and over-stock blood collection, on the occurrence of errors was analyzed, and an ordered logistic regression model was established. After optimizing overall planning measures, the occurrence of errors and the improvement of burnout were compared. 【Results】 In addition to the volume of blood collected (P>0.05), the other five variables had significant influence on the occurrence of errors (P0.05). 【Conclusion】 Scientific inventory management and effective blood collection assessment measures are helpful to improve work quality, and the ordered Logistic regression model has a good fitting degree for error rectification. Analyzing the occurrence of errors during blood collection and supply from the influencing factors is conducive to formulate corrective and preventive measures and promote the continuous improvement of work quality.

Correlation between life events and apheresis platelet donors lapsing / 中国输血杂志

【Objective】 To explore the causes of apheresis platelet donors lapsing in Huzhou area, so as to provide basis for better maintenance of blood donor team. 【Methods】 The data of 1 128 platelet donors from November 1, 2018 to October 31, 2021 were collected, and they were divided into regular blood donor group and lapsed blood donor group, and their work situation, social relations and donation process were investigated through questionnaire survey.Based on the basic characteristics of blood donors, 15 variables were set and analyzed by t test, chi-square test and multivariate logistic regression analysis using SPSS 23.0 software. 【Results】 There were 602 (53.37%, 602/1 128) regular blood donors and 526 (46.63%, 526/1 128) lapsed blood donors in the donor bank during recent 3 years.No significant differences were found in age, gender, educational background, blood donation reaction as well as the satisfaction to service attitude and technical level of blood station staff between the two groups (P>0.05), but significant difference was noticed in whether they were freelancers or changed jobs recently, the working hours per week (h), whether they had friends who donated platelets, had relatives who received/had a serious disease, had children or not, whether satisfied with the frequency of recruitment, and whether the donation was convenient (P<0.05, P<0.01). Multivariate logistic regression analysis showed that recruitment frequency (OR=2.679), convenience of blood donation (OR=2.486), having friends who donated blood (OR=1.791), the working hours per week (OR=1.011), changing jobs (OR=0.558) and having children (OR=0.465) were included in the final regression model and were the influencing factors of blood donor lapsing(P<0.01). 【Conclusion】 Platelet donor lapsing is prominent in Huzhou, therefore efficient communication approaches should be established between blood stations, between blood donors and blood donor, and between blood banks; personalized service should be adopted to maintain apheresis platelet donors.

Silencing AEBP2 Inhibits the Proliferation and Migration of Hepatocellular Carcinoma Cells via the PI3K/Akt Signaling Pathway / 中国生物化学与分子生物学报

Adipocyte enhancer binding protein 2, as a component protein of Polycomb repressive complex (PRC2), is involved in the proliferation and migration of many tumor cells. However, its role in HCC is still unclear. In this study, we identify that AEBP2 was upregulated in HCC samples from the UALCAN and Kaplan-Meier Plotter database, which was correlated to the overall survival time of HCC patients. Real-time quantitative PCR and Western blotting confirmed that the expression of AEBP2 in HCC cells was higher than normal liver cells. After silencing AEBP2 in HepG2 and Huh-7 cells, the effects of the proliferation, apoptosis, migration and invasion were detected by colony formation, CCK-8, flow cytometry, scratch healing and Transwell chamber, respectively. Compared with the control group, down-regulation of AEBP2 expression inhibited the proliferation, migration and invasion in HepG2 and Huh-7 cells, as well as promoted apoptosis (P<0. 05). Immunofluorescence and Western blotting results showed that AEBP2 silencing inhibited epithelial-mesenchymal transformation (EMT) (P < 0. 05). Bioinformatics analysis showed that AEBP2 is involved the PI3K/Akt signaling pathway. Western blotting results confirmed that silencing AEBP2 down-regulated the expression levels of PI3K, p-AKT (S473), mTOR, MMP-2 and MMP-9 proteins (P<0. 05). In addition, the effects of AEBP2 silencing on HepG2 cells migration and invasion could be reversed by PI3K/Akt pathway agonist insulin-like Growth Factors (IGF-1) (P < 0. 01). In summary, our study showed that AEBP2 promoted the proliferation and migration of HCC cell by regulating PI3K/AKT pathway. This study provided a theoretical basis for the role of AEBP2 in HCC.

The Patatin-like Phospholipase Domain Containing Protein 7 (PNPLA7) Facilitates M2 Polarization of Macrophages Through a PPARγ-Dependent Mechanism / 中国生物化学与分子生物学报

Lysophosphatidylcholine (LPC) modulates the dynamic and integral process of macrophage polarization in immune responses, tissue inflammation and remodeling. Patatin-like phospholipase domain containing protein 7 (PNPLA7) was identified as an LPC-preferring lysophospholipase recently. However, the expression and role of PNPLA7 in macrophage polarization remained unknown. In the present study, PNPLA7 was found to be upregulated in the process of macrophage polarization toward an alternatively activated (M2) phenotype stimulated with interleukin 4 (IL-4) (P<0.05). We found that knockdown and overexpression of PNPLA1 decreased and increased the expression of M2 marker genes, including arginase 1 (Argl) and chitinase-like 3 (Ym\ ), respectively (P<0.05). Further studies showed that PNPLA7 regulated the expression of peroxisome proliferator activated receptor-γ (P P A R γ) at the mRNA and protein levels during M2 polarization (P < 0.05). However, the phosphorylation of signal transducer and activator of transcription 6 (STAT6) was not influenced by PNPLA7. These findings suggest that PNPLA7 favors macrophage anti-inflammatory M2 polarization through a PPAR

General screening principles and inheritance paths of classic prescriptions in Tibetan medicine / 中国中药杂志

Due to the profound theoretical rationale, perfect diagnosis and treatment system, and characteristic medicinal resources, Tibetan medicine has been passed down to the present day as one of the four traditional medicine systems all over the world. With the development of modern society and the change in people's concept of seeking medical services, Tibetan medicine has gradually attracted wide attention by virtue of its natural, green and safe diagnosis and treatment characteristics, which enables it to be vigo-rously developed and inherited. There are numerous ancient books on Tibetan medicine, covering a large number of ancient prescriptions, which has laid a solid foundation for later scholars to thoroughly investigate the diagnosis and treatment rules in Tibetan medicine and apply them to modern clinical practice. Screening the classic prescriptions that meet modern clinical needs from those numerous ancient books is a new direction in the inheritance and development of Tibetan medicine. On the basis of historical origin and current application status of ancient prescriptions in Tibetan medicine, this paper preliminarily elaborated the definition of classic prescriptions of Tibetan medicine and their general screening principles and precautions, and also discussed the modern inheritance paths of classic prescriptions in Tibetan medicine from basic research, post-marketing evaluation, and the development of novel preparations. Considering the shortcomings in the present study, the key technical issues mentioned need to be more deeply explored and analyzed in future studies.

Report standards for clinical comprehensive evaluation of Chinese patent medicine / 中国中药杂志

The clinical comprehensive evaluation of drugs is an important basis for the return of clinical value, decision-making of medical and health authorities, and allocation of medical resources. In July 2021, the National Health Commission issued the Guidelines for the Management of Clinical Comprehensive Evaluation of Drugs(trial version 2021), which required the evaluation to be implemented from the six dimensions(safety, effectiveness, economy, innovation, suitability, and accessibility), and made detailed arrangements for the clinical comprehensive evaluation of drugs. As Chinese patent medicine differs from chemical medicines in terms of effective components and action modes, the clinical comprehensive evaluation of Chinese patent medicine should highlight the characteristics and advantages of traditional Chinese medicine(TCM) on the basis of general requirements of comprehensive clinical evaluation of drugs. At present, in the clinical comprehensive evaluation of Chinese patent medicine, unified report standards have not yet been generated, resulting in the uneven quality of existing reports. To standardize the clinical comprehensive evaluation report of Chinese patent medicine and improve its quality, the editorial team, based on the relevant policy documents of clinical comprehensive evaluation of drugs, formulated the clinical comprehensive evaluation report standards for Chinese patent medicine in combination with the previous practice and expert opinions. The report standards, containing seven sections with 15 items determined, focus on data source, evaluation content, evidence synthesis, quality control, and evaluation results supported with detailed interpretations to help researchers better understand and apply the report standards for clinical comprehensive evaluation of Chinese patent medicine, improve the report quality, and provide references for the decision-making by the national medical management authorities.

Analysis of glycosylated hemoglobin in apheresis platelet donors / 中国输血杂志

【Objective】 To investigate the level of glycosylated hemoglobin (HbA1c) in apheresis platelet donors, so as to further ensure the safety of apheresis platelet donors and provide guidance for the recruitment strategy. 【Methods】 Apheresis platelet donors from July 2018 to December 2020 were selected and venous blood was drawn. The glycosylated hemoglobin detection was conducted for donors who had never did this before or did this 3 months ago, and glycosylated hemoglobin >6.0% was regarded as abnormal. 【Results】 A total of 986 blood donors were detected, among which 32 donors with abnormal glycosylated hemoglobin were found, rated at 3.25%. With the increase of age and BMI(height and body mass index), the proportion of abnormal glycosylated hemoglobin increased, but the 51~60 age group and BMI > 28.0 group were not the highest, which may be related to the source of samples.The rate of abnormal glycosylated hemoglobin was highest in 40~50 years old group (5.43%, 15 / 276) and BMI ranged of 24.0~27.9 (4.04%, 9 / 223), and lowest (0.85%, 1 / 118) in 18~25 years old group and BMI >28.0(none). 【Conclusion】 The abnormal glycosylated hemoglobin is closely related to age and BMI. Therefore, we should give priority to young and underweight donors when recruiting blood donors, which can improve efficiency and maximize the safety of blood donors.

Evaluation on the laparoscopic repair in children with ureterovesical junction malformation through internal or external bladder / 中华实用儿科临床杂志

Objective:To evaluate the therapeutic characteristics of laparoscopic repair in children with ure-terovesical junction malformation through internal or external bladder.Methods:From February 2018 to August 2019, 29 cases of hydronephrosis combined with ureter expansion treated in the First Affiliated Hospital of Zhengzhou University, with 17 boys and 12 girls confirmed through the preoperative examinations.Inspection results revealed 15 cases of ureteropelvic junction obstruction, 12 cases of vesicoureteral reflux, and 2 cases of single ectopic ureter.Totally, 21 cases were treated by pneumovesical laparoscopic Cohen means, including 17 unilateral cases and 4 bilateral cases, 5 cases of ureterocele, and 8 cases of ureteral clipping.A total of 8 cases were treated by laparoscopic Lich -Gregoir surgical treatment, including 7 unilateral cases and 1 bilateral case.Meanwhile, 4 cases of ureteral clipping were performed among them.There was 1 case of duplex kidney with the ectopic upper ureter outside iliac blood vessels, 1 case of bilateral cryptorchidism and 1 case of unilateral cryptorchidism.Ureteral stents were implanted for those with ureteral tailoring.The catheters were removed 7 days after operation, and the indwelling ureteral stents were removed by cystoscope under general anesthesia after about 6 weeks.Results:All the cases with hydronephrosis and ureteral dilatation were completed in laparoscopic surgery, without open surgery or blood transfusion, 21 cases were treated by pneumovesical laparoscopic Cohen means, with the average time being 1.8 hours in unilateral side and 2.8 hours in bilateral sides.At the same time, 8 cases were treated by laparoscopic Lich-Gregoir means, with the unilateral average time being 1.7 hours and bilateral time being 3.0 hours.All cases were followed up at an average month of 9 (4-20 months), and all children underwent voiding cystourethrography 4 months after the operations.The voiding cystourethrogram(VCUG) of all the cases was confirmed successfully, with only 1 case of vesicoureteral reflux in level Ⅲ, and their hydronephrosis were relieved.There was no vesicoureteral reflux in the others.The short-term urinary retention occurred in 1 patient with bilateral ureteral reimplantation in Lich-Gregoir group, and the symptom disappeared after 1 week of indwelling catheterization.Among them, 1 patient in Cohen group had hematuria that disappeared gradually for 4 days after surgery.There were no significant differences in operation time and postoperative recovery between the two groups.The length of hospital stay in laparoscopic Lich -Gregoir group was slightly longer than that in pneumovesical laparoscopic Cohen group.Conclusions:As for children with ureterovesical junction malformation, laparoscopic Lich-Gregoir surgery is suitable for the ectopia of ureter opening, overexpansion of ureter, and other abdominal malformation complicated and expansive ureter without tortuosity.Pneumovesical laparoscopic Cohen surgery is suitable for hydronephrosis and ureteral expansion with ureterocele, especially with the symptom of dysuria, and ureteral tortuosity obviously.The two ways are safe and reliable, and the advantages and disadvantages should be weighed before being chosen.

Objective To discuss the operation timing,clinical efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of acute biliary pancreatitis.Methods Retrospective analyzed the clinical data of 65 acute biliary pancreatitis patients in First People's Hospital of Jiangxia District,Wuhan city form October 2015 to July 2017,there were 45 males and 30 females,the age was (46.35 ± 8.95) years (range,25-72 years).All patients were treated with ERCP,and divided into 24-72 h group (the time from onset to ERCP treatment 24-72 h) 16 cases,72-120 h group (the time from onset to ERCP treatment 72-120 h) 25 cases and ≥ 120 h group(the time from onset to ERCP treatment ≥ 120 h) 34 cases,recorded and compared the clinical indexes during and after operation,laboratory indexes before and after treatment,incidence of surgical complications,recurrence rate and mortality.The measurement data with normal distribution were expressed as mean ± standard deviation (Mean ± SD),the F test was used for comparison among the three groups,and the t test was used for comparison between the two groups,the count data were compared by x2 test,and the rank sum test was used to compare the incidence of surgical complications.Results The abdominal pain relief time,amylase recovery time,length of stay and hospitalization expenses of the 24-72 h group were (4.48 ± 1.29) d,(3.59 ± 1.22) d,(7.24±1.55) d and (1.55 ±0.31) ten thousand yuan respectively,the 72-120 h group were (7.35 ± 1.76) d,(4.91 ±1.37) d,(13.61 ±2.13) d,(2.02 ±0.37) ten thousand yuan respectively,the ≥120 h group were (11.21 ±2.02) d,(8.86±1.95) d,(21.58±2.86) d,(2.49±0.52) ten thousand yuan respectively,with significant differences between any two groups(P ＜0.05).The serum amylase,total bilirubin,c-reactive protein and white blood cell levels of the 24-72 h group were (319.65 ±58.93) U/L,(14.22 ± 2.84) μmol/L,(31.12 ± 5.35) mg/L and (6.84 ± 1.17) × 109/L respectively,the 72-120 h group were (362.87 ±63.37) U/L,(16.39 ± 3.14) μmol/L,(37.34 ± 6.12) mg/L and (7.93 ± 1.36) x 109/L respectively,the ≥ 120 h group were (452.61 ± 75.49) U/L,(20.28 ± 3.67) μmol/L,(46.19 ± 6.98) mg/L and (9.77 ± 1.52) x 109/L respectively,with significant differences between any two groups (P ＜ 0.05).The incidence of surgical complications,recurrence rate and mortality of the 24-72 h group were 25.00％ (4/16),12.50％ (2/16) and 0 (0/16) respectively,the 72-120 h group were 24.00％ (6/25),12.00％ (3/25) and 0 (0/25) respectively,the ≥120 h group were 29.41％ (10/34),20.59％ (7/34) and 5.88％ (2/34) respectively,with significant differences between 24-72 h group,72-120 h group and ≥ 120 h group (P ＜ 0.05);But there was no significant difference between the 24-72 h group and the 72-120 h group (P ＞0.05).Conclusion In the treatment of acute biliary pancreatitis within 24-72 h and 72-120 h are safe and effective,but the improvement of laboratory indexes within 24-72 h ERCP treatment is more obvious,the length of stay is shorter,the hospitalization expenses is more provincial,and with more clinical advantage.

Correlation between galectin-3 level in bronchoalveolar lavage fluid and cellular immunity in children with refractory Mycoplasma pneumoniae pneumonia / 中国当代儿科杂志

OBJECTIVE@#To study the correlation of galectin-3 level in bronchoalveolar lavage fluid (BALF) with Mycoplasma pneumoniae (MP) load and cellular immunity of neutrophils and macrophages in the airway in children with refractory MP pneumonia (RMPP).@*METHODS@#A total of 64 children with RMPP who were hospitalized from January 2013 to January 2017 were enrolled. In addition to the conservative medical treatment, all the 64 children with RMPP were given bronchoalveolar lavage in the acute stage (5-7 days after admission) and 48 out of the 64 children were given bronchoalveolar lavage in the recovery stage (10-14 days after admission). Four milliliters of BALF of the affected lung lobe or segment were collected. ELISA was used to measure the level of galectin-3 in BALF supernatant. RT-PCR was used to measure MP load. Hematoxylin and eosin staining was used to measure the percentage of neutrophils and macrophages. Six children with bronchial foreign bodies were enrolled as the control group.@*RESULTS@#The RMPP group had a significantly higher level of galectin-3 in BALF in both the acute and recovery stages than the control group (P0.05). The RMPP group had a significantly higher MP load in BALF in both the acute and recovery stages than the control group (P<0.01), and the MP load in the acute stage was significantly higher than in the recovery stage (P<0.01). In the children with RMPP, galectin-3 level in BALF in the acute stage was positively correlated with MP load and the percentage of neutrophils (r=0.789 and 0.726 respectively; P<0.01).@*CONCLUSIONS@#Galectin-3 is involved in the process of airway inflammation in children with RMPP, and the level of galectin-3 in BALF is positively correlated with MP load. RMPP is a cellular immune inflammatory lesion with the increase of neutrophils and the reduction in macrophages. Galectin-3 is closely associated with neutrophil chemotaxis and luminal infiltration in children with RMPP. MP load gradually decreases with the recovery from RMPP, but it is not completely eliminated by the immune system in the recovery stage. MP infection can increase the consumption of macrophages in children with RMPP.

Effect of group cognitive behavior intervention on self-rated health of middle school students with e-motional disorder / 中华行为医学与脑科学杂志

Objective To explore the effect of group cognitive behavior intervention on self-rated health of middle school students with emotional disorders. Methods From January 2018 to June 2018,79 middle school students with emotional disorders were randomly divided into intervention group ( 41 cases) and control group (38 cases) according to the single or double number of medical records. The control group only received drug treatment,while the intervention group received group cognitive behavior intervention on the basis of drug treatment. All the students in the two groups completed the self-rated health measurement scale before intervention (T0),after intervention (T1) and 8 weeks after intervention (T2). Results (1) There were no significant differences in total health score and dimension score between the two groups before intervention (both P<0. 05). (2)The repeated measurement variance analysis showed that there was a signif-icant group × time interaction effect on total health score and dimensions(P>0. 05). (3) The group effect of physical health was not significant (P>0. 05). The group effect of total mental health, social health and health score at T1 and T2 time points were significant (all P>0. 05). (4)Compared with before intervention, mental health ((123. 34±9. 33),( 122. 63± 9. 11)),social health ((102. 89 ± 7. 28),( 101. 89± 7. 73)) and total health score ((370. 34±17. 99),(367. 63±17. 89)) of intervention group at T1 and T2 increased ( all P<0. 05),while that of control group increased only at T1 (all P<0. 05). Conclusion Group cognitive behavioral intervention has no obvious effect on physical health of middle school students with emotional dis-orders. And group cognitive behavioral intervention can effectively improve their mental health,social health and overall health level,and the long-term effect is better.
