Objective To assess the methodology,reporting quality and intervention reporting quality of randomised controlled trials(RCT)of acupuncture for chronic obstructive pulmonary disease(COPD).Methods Randomized controlled trials of acupuncture for the treatment of chronic obstructive pulmonary disease from the establishment of the database to March 1,2023 through computer system search of CNKI,Wanfang,VIP,SinoMed,and PubMed databases.Two researchers independently conducted literature search,relevant data extraction,etc.,and assessed the quality of reports using the bias assessment tools ROB2,CONSORT Extended Statement and STRICTA List of Cochrane Systematic Review Manuals.Results After excluding non-compliant articles through the developed exclusion criteria,31 RCT remained.A methodological assessment of the included RCT according to the Cochrane website bias assessment tool ROB2 showed that 9 studies(29.03%)were at high risk of bias and no studies at low risk of bias.The CONSORT extended statement based on non-drug randomized controlled trials evaluated the quality of the literature,indicating that the reporting rate in terms of methods,results,trial protocol registration,etc.was low.The results of the evaluation according to the entries in the STRICTA list show that most of the literature does not describe the details of acupuncture and the background of the therapist in sufficient detail,but the reasonableness of acupuncture treatment is relatively complete.Conclusion At present,the quality of randomized controlled trials of acupuncture for COPD is generally low,and it is recommended that future researchers strictly follow the internationally recognized CONSORT statement and STRICTA list for trial protocol design and study result reporting.

Objective : To investigate the effects of milk derived pentapeptide prolin⁃glycine⁃proline⁃isoleucine⁃pro⁃ line ( PGPIP) on chronic alcoholic liver injury in mice and its related molecular mechanism . Methods : Forty C57BL/6 mice were randomly divided into control group , model group , glutathione(GSH) group , PGPIPN group .The mice model of chronic alcoholic fatty liver was established by 10 d ad libitum oral feeding with the Lieber⁃DeCarli(LD) ethanol liquid diet plus one binge . Drug intervention was given at the same time . Based on the reported RNA sequencing data in gene expression omnibus (GEO) database , the differential expression of liver endoplasmic reticulum stress⁃related genes was analyzed by cluster heat map . Liver hematoxylin⁃eosin (HE) staining was used to analyze the pathological effects of each treatment group on alcoholic liver injury in mice . Oiled Red O staining was used to analyze the effects of each treatment group on the accumulation of liver lipid droplets in mice . Transtransduction protein expression was detected by Western blot . Results : The pathological examination of PGPIP group was similar to that of Control group , and the liver injury of mice was significantly reduced . The accumulation of lipid droplets in the liver of mice in the model group was manifested as mixed lipid droplets of different sizes , and PGPIP treatment significantly reduced the accumulation of liver lipid droplets induced by alcohol . PGPIP had significant effects on the PERK⁃eIF2α⁃ATF4 pathway and the expression of transcriptional activator 6 ( ATF6 ), Cleaved Caspase 3 protein . Conclusion Pentapeptide PGPIP can alleviate chronic alcoholic fatty liver and liver injury in mice . The mechanism may be attributed to reducing the accumulation of lipid droplets in hepatocytes , en⁃ doplasmic reticulum stress , and hepatocyte apoptosis .

Objective : To investing ate the milk-derived hexapeptide PGPIPN and its truncated pentapeptide PGPIP to alleviate chronic alcoholic liver injury in mice and its associated molecular mechanisms． Methods : Sixty Kun- ming mice were randomly divided into control group，model group，GSH group，PGPIPN group，and truncated pen- tapeptide PGPIP group．The model of chronic alcoholic liver injury in mice was established by gavage with gradient alcohol． Drug intervention was given at the same time for 12 weeks． Liver HE staining was used to analyze the pathological effects of each treatment group on alcoholic liver injury in mice．Primary mouse hepatocytes and human normal hepatocyte line L-02 were isolated and cultured in vitro．The appropriate PGPIPN induction concentrations of both cells were determined by WST-1 method． L-02 cells were induced at different times． The expression of FoxO3a and phosphorylated FoxO3a protein were detected by Western blot to determine the appropriate induction time．The subcellular localization of FoxO3a in L-02 cells was detected by cellular immunofluorescence．The mR- NA changes of FoxO3a and MnSOD genes in primary hepatocytes and L-02 cells of mice in different treatment groups were detected by qRT-PCR. Results : The pathological examination of PGPIPN group and PGPIP group was similar to that of GSH group，and the liver injury of mice was significantly reduced．Medium and high concentra- tions of PGPIPN were respectively selected to induce mouse primary hepatocytes and L-02 cells．At 16 hours，the expression of FoxO3a protein in L-02 cells increased significantly．FoxO3a protein was mainly expressed in the nu- cleus．In addition，mRNA levels in both types of cells increased significantly after induction with the corresponding dose of PGPIPN． Conclusion PGPIPN and truncated pentapeptide PGPIP can reduce chronic alcoholic liver injury in mice．The mechanism may be to reduce alcohol-induced oxidative stress through FoxO3a-MnSOD signaling path- way.

Ca2+ leak via ryanodine receptor type 2 (RyR2) can cause potentially fatal arrhythmias, and RyR2 mutations have been shown in the aetiology of catecholaminergic polymorphic ventricular tachycardia. We report the case of a patient with catecholaminergic polymorphic ventricular tachycardia resulting from a RYR2 mutation who had not only typical electroencephalogram changes, but also epileptiform discharges in electroencephalogram. We believe the changes were closely related to the RYR2 mutation.

Objective To explore the association of serum cytokine levels with disease activity in patients with dermatomyositis (DM) and clinically amyopathic dermatomyositis (CADM),especially their association with skin lesions and interstitial lung disease (ILD).Methods Enzyme-linked immunosorbent assay (ELISA) and cytometric beads array (CBA)were performed to detect the serum levels of interleukin (IL)-2,IL-4,IL-6,IL-10,IL-17A,IL-18,tumor necrosis factor (TNF) and interferon (IFN)-γin 40 patients with DM or CADM,as well as in 16 health checkup examinees (healthy control group).Then,the association of serum cytokine levels with skin lesions,inflammatory biomarkers and severity of ILD was analyzed.Results The patients with DM/CADM showed significantly higher serum levels of IL-6 (37.8 ±45.8 pg/ml),IL-10 (16.1 ± 7.2 pg/ml) and IL-18 (492.0 ± 193.1 pg/ml) compared with the healthy controls (12.0 ± 2.7 pg/ml,7.7 ± 1.4 pg/ml,191.1 ± 39.2 pg/ml,respectively,all P ＜ 0.001),and there were no significant differences in the serum levels of the other 5 cytokines between the above 2 groups.The serum level of IL-6 was significantly higher in patients with elevated erythrocyte sedimentation rate (ESR) than in those with normal ESR (49.7 ± 46.8 pg/ml vs.29.1 ± 45.4 pg/ml,P =0.008).The patients with raised C-reactive protein (CRP) levels showed significantly higher serum levels of IL-6 (68.7 ± 59.7 pg/ml) and IL-18 (635.1 ± 232.8 pg/ml) compared with those with normal CRP levels (IL-6:30.6 ± 40.3 pg/ml,P =0.013;IL-18:440.2 ± 164.7 pg/ml,P =0.020).Moreover,the patients with elevated levels of lactate dehydrogenase (LDH) showed significantly higher serum levels of IL-10 (18.4 ± 6.9 pg/ml),IL-17A (19.6 ±6.7 pg/ml) and IL-18 (529.4 ± 197.2 pg/ml) compared with those with normal LDH levels (IL-10:10.7 ±4.8 pg/ml,P ＜ 0.001;IL-17A:11.4 ± 6.6 pg/ml,P =0.001;IL-18:404.9 ± 158.0 pg/ml,P =0.037).No significant difference in the cytokine levels was observed between the patients with elevated creatine kinase (CK) levels and those with normal CK levels.The patients with Gottron's papules/sign showed significantly higher serum levels of IL-18 (513.7 ± 187.2 pg/ml) compared with those without Gottron's papules/sign (297.1 ± 140.4 pg/ml,P ＜ 0.05).The serum levels of IL-10 and IL-18 were significantly higher in the patients with DM/CADM complicated by ILD (18.0 ± 6.7 pg/ml,552.3 ± 192.8 pg/ml,respectively) than in those without ILD (11.6 ± 6.5 pg/ml,351.4 ± 101.0 pg/ml,respectively,both P =0.001).Conclusion Serum levels of IL-6,IL-10 and IL-18 are highly associated with inflammatory biomarkers,skin lesions and ILD in patients with DM/CADM.

Objective: To investigate the prevalence and related factors of dyslipidemia among children and adolescents aged 6-17 years in 7 provinces in China. Methods: Using the method of stratified cluster random sampling, 93 primary and secondary schools were selected from Guangdong, Hunan, Liaoning provinces, Shanghai, Chongqing, Tianjin municipalities and Ningxia Hui Autonomous Region in China, 2012. A total of 16 434 students aged 6-17 years old with completed physical and lipid profiles parameters were selected into this study from above 93 primary and secondary schools. Dyslipidemia was determined by the definition of Expert Advice on Prevention and Treatment of Dyslipidemia in Children and Adolescents in 2009. Logistic regression model was used to explore the factors related to dyslipidemia. Results: The prevalence of elevated total cholesterol, elevated triglyceride, elevated low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol, and dyslipidemia was 5.4% (887 cases), 15.7% (2 578 cases), 3.0% (492 cases), 13.5% (2 221 cases) and 28.5% (4 679 cases) among children and adolescents aged 6-17 years, respectively. Sugary drinks intake ≥once per week (OR=1.14; 95%CI: 1.05-1.24), sedentary time >10 hours per day (OR=1.14, 95%CI: 1.01-1.28), overweight (OR=1.50, 95%CI: 1.33-1.70), and obesity (OR=2.62, 95%CI: 2.31-2.96) were significantly associated with the prevalence of dyslipidemia. Conclusion The prevalence of dyslipidemia was high among children and adolescents aged 6-17 in 7 provinces in China, 2012. Sugary drinks intake ≥once per week, sedentary time >10 hours per day, overweight and obesity might be the risk factors of dyslipidemia among children and adolescents.

The expression of dentin sialophosphoprotein (DSPP) is the marker for cells differentiated into odontoblasts. This study attempted to analyze the DSPP promoter and build the reporter LacZ expression system driven by this promoter, which allows convenient and quick detection of odontoblast cells. First, we separated the human dental mesenchymal cells in which the expression of DSPP can be effectively induced by dexamethasone. Second, four 5' flanking regions of human DSPP gene (- 4 000-+54, -2 500-+54, -1 447-+54 and -1 027-+54) were analyzed, the results showed that the highest promoter activity lied in the -2 500-+54 region. The promoter activity is reduced when the 5' flanking region was extended from -2 500 to -4 000 bp upstream from the transcription start site; The promoter activity are also decreased when the 5' flanking regions were shorted from -2 500 to -1 447 bp and from -1 447 to -1 027 bp, indicating that potential suppresser elements are lied in the region between -4 000 and -2 500 bp and potential activator elements are lied in the region between -2 500 and -1 027 bp. Then we constructed the lentiviral report vector phDSPP-LacZ containing the -2 500-+ 54 promoter region in front of the LacZ gene. The expression of LacZ was detected using X-Gal staining in both human dental mesenchymal cells and immortalized human dental mesenchymal cells infected with phDSPP-LacZ. The phDSPP-LacZ lentiviral vector may provide a more convenient method to detect the expression of DSPP in human odontogenic differentiation, tooth development and tooth regeneration studies.

OBJECTIVETo analyze the influence factors of body image dissatisfaction among children and adolescents with normal weight.

METHODSThe primary and middle school students who were selected from Changping district of Bejing city using the stratified cluster sampling method were measured body height, weight, and waist circumference. Body image cognitive attitude of students or their parents was surveyed using 'Ma figural shape'. The cognitive attitude of obesity risk factors was surveyed by self-designed questionnaires. The students with normal weight were selected according to 'reference norm for screening overweight and obesity in Chinese children and adolescents (WGOC) in 2005' and 'reference norm for screening underweight in Chinese children and adolescents aged 6-19 years'. The association between body image dissatisfaction and cognitive attitude of obesity risk factors was analyzed for each gender.

RESULTSThe study validly surveyed and measured 680 students, and there were 36.6% (249/680) students with overweight or obesity, 4.0% (27/680) students with underweight, and 59.4% (404/680) students with normal weight. Prevalence of body image satisfaction, expecting to be thinner, and to be fatter in students with normal weight was 32.7% (132/404), 35.1% (142/404), and 32.2% (130/404), respectively. The prevalence of expecting to be thinner in females and middle students was higher than that in males and primary students (46.4% (102/220) vs 21.8% (40/184)), (39.8% (88/221) vs 29.5% (54/183)), respectively; χ² values were 26.65 and 4.67 respectively (P < 0.05). The prevalence of expecting to be fatter in males was higher than that in females ((42.9% (79/184) vs 23.2% (51/220)) (χ² = 17.91, P < 0.001). The concordance ratio on body image cognitive attitude between students and their parent was 60.4% (244/404), and the consistency coefficient was 0.41 (P < 0.001). The factors including parents expecting their children to be thinner, the negative attitude on less drinking sugary beverages and having breakfast per day might increase the risks of children expecting to be thinner in males, the OR (95% CI) value were 5.20 (1.51-17.89), 3.43 (1.11-10.59), and 6.53(1.14-37.58), respectively. The parents expecting their children to be fatter might increase the risk of children expecting to be fatter in males, the OR (95% CI) value were 7.57 (3.47-16.52). The factors including parents expecting their children to be thinner, and the positive attitude on less eating high calorie snacks might increase the risk of children expecting to be thinner in females, the OR (95% CI) value were 65.74 (8.45-511.21) and 3.03 (1.01-9.09), respectively. The parents expecting their children to be thinner or fatter might increase the risk of children expecting to be fatter in females, the OR (95% CI) value were 17.38 (1.53-197.74) and 9.64 (3.98-23.35), respectively.

CONCLUSIONThe prevalence of body image dissatisfaction among students with normal weight was high, and the concordance ratio on body image cognitive attitude between themselves and their parents was low. Guiding students to have the correct cognitive attitude on less drinking sugary beverages, having breakfast per day, and less eating high calorie snacks may be conducive to prevent body image dissatisfaction.
