Objective: To analyze the research hotspots and advancements in weight management for obese children both domestically and internationally, providing a theoretical foundation for future studies of related fields. Methods: Relevant literature for weight management of obese children were retrieved from CNKI, Wanfang, Weipu, Web of Science (WOS) databases for the period from January 1, 2014, to December 31, 2024. Excel, CiteSpace, and VOSviewer were used to analyze annual publication volume, authors, institutions, keywords, and other bibliometric characteristics. Results: A total of 158 Chinese literature and 484 English literature were included. Domestic publications remained stable, while international publications fluctuated but stabilized during 2018-2022. The publication volume and institutional collaboration map indicated that foreign scholars collaborations were concentrated, whereas domestic collaborations were scattered. The foreign scholar with the highest number of publications was Ball (29 articles). And the country with the most publications was the United States (256 articles). Journal dual map overlay indicated future would focus on medicine, internal medicine and clinical medicine. Both domestic and foreign studies focused on participants, weight management methods and monitoring indicators, with foreign studies further exploring research methods. Conclusions In the past decades, weight management methods and specific measures have been a primary focus in this field, with distinct priorities observed between domestic and international scholars. In the future, international exchanges and cooperation should be strengthened, and weight management plans for obese children with Chinese characteristics should be developed according to actual conditions.

BACKGROUND:Numerous scholars have previously researched certain greater tuberosity fractures and the procedures used to treat them.Few researchers,however,have studied the comminuted split fracture of the greater tuberosity of the humerus(Liu-Gang type IV)with rotator cuff tear in great detail. OBJECTIVE:To compare the clinical therapeutic effect of open repair position modified calcaneal plate combined with suture anchors and proximal humeral internal locking system(PHILOS)plate in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV). METHODS:Case data of 30 patients with comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)from May 2012 to May 2022 were retrospectively analyzed.They were divided into the modified calcaneal plate combined with suture anchor group(group A)and the PHILOS with#2 Johnson group(group B),with 15 cases in each group.Intraoperative blood loss,surgical time,and incision length of all patients were recorded.Pain visual analog scale score,Constant-Murley score,as well as shoulder joint abduction,forward flexion,external rotation,and dorsal expansion activities during the last follow-up(>1 year)were evaluated. RESULTS AND CONCLUSION:(1)The surgical incision length and operation time were shorter,and blood loss was less in group A than those in group B(P<0.05).(2)No significant difference in visual analog scale score and Constant-Murley score was detected between the two groups(P>0.05).(3)During the last follow-up,forward flexion in group A was better than that in group B(P<0.05).No significant difference in abduction,external rotation,and dorsal expansion was determined between group A and group B(P>0.05).(4)In terms of complications,there was 1 case of shoulder joint pain and discomfort in group A(7%),2 cases of subacromial impingement syndrome,2 cases of upward movement of nodules,and 2 cases of shoulder joint pain(40%)in group B.There were significant differences in complication rates between the two groups(P=0.031).(5)In summary,the modified calcaneal plate combined with suture anchors in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)could better restore the forward flexion function of the shoulder joint and has a small incision,less blood loss,shorter operation time and fewer complications.

Objective To investigate the role of sodium-glucose cotransporter 1(SGLT1)inhibitor mizagliflozin(MIZA)in autosomal dominant polycystic kidney disease(ADPKD).Methods Western blotting,quantitative polymerase chain reaction(qPCR),and immunofluorescence staining were used to determine the expression and distribution of SGLT1 in kidney tissues of PKD1-/-and PKD1+/+mice,human renal cancer adjacent tissue and ADPKD tissue.Renal cyst lining epithelial cells OX161 and renal tubular epithelial cells UCL93 were treated with MIZA,incubated at 37℃for 24,48,and 72 h,and then were subjected to methyl thiazolyl tetrazolium and colony formation assay to observe cell proliferation.The qPCR method was used to determine the mRNA levels of collagen 1α1,collagen 3α1,and fibronectin 1 in OX161 cells treated with 100 μmol/L MIZA for 48 h.The Madin-Darby canine kidney(MDCK)cell 3D cyst formation assay verified the effect of MIZA on cyst formation.The mRNA-seq technology was used to detect differentially expressed genes between UCL93 cells and OX161 cells,and between OX161 cells and OX161 cells treated with 100 μmol/L MIZA for 48 h,and then the differentially expressed genes were analyzed with Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis.Results The expression level of SGLT1 was significantly increased in the tissues of ADPKD patients and PKD1-/-mice compared to those in normal kidney tissues(P＜0.05,P＜0.01).Immunofluorescence staining revealed that SGLT1 was mainly expressed in the cystic lining epithelial cells.Additionally,MIZA inhibited the proliferation and fibrosis of polycystic kidney cells in a concentration-and time-dependent manner,and also inhibited cyst formation in 3D formation assay in vitro.The mRNA-seq analysis and KEGG enrichment analysis showed that differentially expressed genes between OX161 cells and OX161 cells cultured in 100 μmol/L MIZA for 48 h were mainly enriched in the phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt)and mitogen-activated protein kinase(MAPK)signaling pathways,which were the same as those between OX161 cells and UCL93 cells.Conclusion The SGLT1 inhibitor MIZA may inhibit the proliferation and fibrosis of polycystic kidney cells through signaling pathways such as PI3K-Akt and MAPK,delaying the growth of polycystic kidney,and it is a potential therapeutic target for ADPKD.

OBJECTIVE To predict the amount of colorants used in the preparation of placebo of Chinese medicine by construc-ting particle swarm optimization-back propagation neural network PSO-BPNN compound granules,and to provide a new idea for the simulation of placebo color of Chinese medicine compound granules.METHODS The BP neural network was used to establish the model of sample color parameters L,a?,b?and pigment mass fraction.The global search ability of particle swarm optimization algo-rithm was used to optimize the weight and bias of BP neural network to prevent the local minimum value of the model.The linear reduc-tion weight coefficient method and the introduction of mutation operator were used to improve the global optimization ability of particle swarm optimization algorithm.The color comprehensive evaluation index(ΔE)was used as the objective evaluation standard to verify the test results.RESULTS The training results show that the fitting accuracy of the improved PSO-BP neural network was up to 98.31%.The prediction results show that the prediction error of the improved PSO-BP neural network was the smallest,and the mean absolute percentage error(MAPE),root mean square error(RMSE)and mean color difference(ΔE)were 0.411 5,2.164 6 and 2.56,respectively.The verification samples of three kinds of particles were prepared for verification.The ΔE of the verification sample and the model drug were 1.73,2.63 and 4.11,respectively.The color difference between the two groups and the model drug was small by visual evaluation.CONCLUSION The BP neural network based on the improved particle swarm optimization algorithm can simulate the prediction of the amount of colorants used in the preparation of Chinese medicine compound granules,and can be used as a recommended optimization model for placebo color matching research.

Objective:To investigate the clinical effect of respiratory intervention training in feeding of preterm infants, so as to provide reference for feeding interventions in preterm infants.Methods:From March 2021 to October 2021, the 80 preterm infants hospitalized in the Neonatal Intensive Care Unit of Xuzhou Central Hospital were selected and divided into intervention group (40 cases) and control group (40 cases) according to the random table method in a prospective study. The common nursing was given in the control group, the respiratory intervention training was given on this basis in the intervention group, once a day for two weeks. The intervention effect was evaluated by the time of indwelling gastric tube, hospital stay, feeding reaction, feeding related complications and satisfaction rate of catch-up growth. The oral feeding ability of preterm infants was evaluated by the non-nutritive sucking (NNS) score and preterm infants oral feeding readiness assessment scale (PIOFRAS) score.Results:The time of indwelling gastric tube and hospital stay was (15.3 ± 8.7), (28.9 ± 9.8) d in the intervention group and (21.7 ± 9.8), (34.6 ± 12.2) d in the control group, the difference was significant ( t=3.12, 2.32, both P<0.05). After intervention, the differences of respiratory number, heart rate and pulse oxygen saturation were (6.5 ± 1.3) beats/min, (11.2 ± 1.5) beats/min, 0.048 ± 0.015 in the intervention group and (11.2 ± 1.2) beats/min, (16.5 ± 1.3) beats/min, 0.082 ± 0.018 in the control group, the differences were significant ( t=16.39, 16.40, 9.35, all P<0.05). The incidence of feeding-related complications was 25.0% (10/40) in the intervention group and 55.0% (22/40) in the control group, the difference was significant ( χ2=7.50, P<0.05). The satisfaction rate of catch-up growth was 77.5%(31/40) in the intervention group and 40.0%(16/40) in the control group, the difference was significant ( χ2=12.78, P<0.05). The scores of NNS and PIOFRAS at 7 d, 10 d and 14 d after intervention were (13.73 ± 2.24), (29.98 ± 6.67), (49.08 ± 16.37) points and (15.28 ± 1.41), (25.08 ± 3.10), (31.03 ± 3.00) points in the intervention group and (10.30 ± 2.18), (15.68 ± 2.42), (28.60 ± 3.61) points and (12.60 ± 1.22), (17.15 ± 1.51), (23.75 ± 3.87) points in the control group, the differences were significant ( t values were -14.53--6.94, all P<0.05). Conclusions:The respiratory intervention training can effectively shorten the transition time from tube feeding to complete oral feeding in preterm infants, reduce feeding reaction and the incidence of feeding-related complications, and promote the coordination of feeding behavior, so as to improve oral feeding ability and catch-up growth of preterm infants.

Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.
