BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

Following the principles of evidence-based medicine,in accordance with the structure and drafting rules of standardized documents,based on literature research,according to the characteristics of chronic cough in children and issues that need to form a consensus,the TCM Guidelines for Diagnosis and Treatment of Chronic Cough in Children was formulated based on the Delphi method,expert discussion meetings,and public solicitation of opinions.The guideline includes scope of application,terms and definitions,eti-ology and diagnosis,auxiliary examination,treatment,prevention and care.The aim is to clarify the optimal treatment plan of Chinese medicine in the diagnosis and treatment of this disease,and to provide guidance for improving the clinical diagnosis and treatment of chronic cough in children with Chinese medicine.

Objective To explore the role of Panax notoginseng saponins(PNS)in regulating the expression of sortilin and ATP-binding cassette transporter A1(ABCA1)in macrophages,and the effect of PNS on inhibiting formation of foam cells and the potential mechanism of PNS adjusting sortilin expression and cholesterol metabolism.Methods The macrophages were divided into five groups as follows:group A(only added with cell culture),group B(transfected with negative control lentivirus),group C(transfected with lentivirus-mediated sortilin overexpression),group D(transfected with lentivirus-mediated sortilin overexpression+60 μg·mL-1PNS),group E(transfected with lentivirus-mediated sortilin overexpression+10 μmol·L-1 mitogen-activated protein kinase kinase(MEK)inhibitor PD98059+60 μg·mL-1 PNS).The protein contents of sortilin,ABCA1,extracellular signal-regulated kinase(ERK)and phosphorylated-ERK(p-ERK)were evaluated with Western blot.All the cells in five groups were cultured with 50 μg·mL-1ox-LDL to form foam cells.The lipid in macrophages was investigated with red O assay.Results The relative expression levels of sortilin protein were 1.00±0.08,0.91±0.15,2.28±0.13,1.62±0.09 and 2.01±0.08;the relative expression levels of ABCA1 protein were 1.00±0.01,0.92±0.07,0.29±0.04,0.66±0.09 and 0.44±0.07;the ratios of p-ERK/ERK protein were 1.00±0.09,0.92±0.05,1.03±0.12,2.00±0.12 and 1.64±0.14;the contents of lipid in macrophages were(4.82±2.19)％,(6.70±0.88)％,(44.56±4.15)％,(27.66±3.25)％and(41.67±5.45)％.Except the ratios of p-ERK/ERK,the other parameters between group C and group A were statistically significant difference(all P＜0.01).Meanwhile,there were also statistically significant difference between group D and group C as well as group D and group E(P＜0.05,P＜0.01).Conclusion PNS inhibits the lipid accumulation in macrophages through upregulating ABCA1 and downregulating sortilin,and ERK signaling pathway may be as one of important mechanisms influencing the expression of sortilin and ABCA1 mediated by PNS.

Objective To explore the diagnostic efficacy of serum 14-3-3β protein combined with fractional exhaled nitric oxide(FeNO)and conventional ventilatory lung function parameters in diagnosing bronchial asthma(referred to as"asthma")in children.Methods A prospective study included 136 children initially diagnosed with asthma during an acute episode as the asthma group,and 85 healthy children undergoing routine health checks as the control group.The study compared the differences in serum 14-3-3β protein concentrations between the two groups,analyzed the correlation of serum 14-3-3β protein with clinical indices,and evaluated the diagnostic efficacy of combining 14-3-3β protein,FeNO,and conventional ventilatory lung function parameters for asthma in children.Results The concentration of serum 14-3-3β protein was higher in the asthma group than in the control group(P<0.001).Serum 14-3-3β protein showed a positive correlation with the percentage of neutrophils and total serum immunoglobulin E,and a negative correlation with conventional ventilatory lung function parameters(P<0.05).Cross-validation of combined indices showed that the combination of 14-3-3β protein,FeNO,and the percentage of predicted value of forced expiratory flow at 75%of lung volume had an area under the curve of 0.948 for predicting asthma,with a sensitivity and specificity of 88.9%and 93.7%,respectively,demonstrating good diagnostic efficacy(P<0.001).The model had the best extrapolation.Conclusions The combination of serum 14-3-3β protein,FeNO,and the percentage of predicted value of forced expiratory flow at 75%of lung volume can significantly improve the diagnostic efficacy for asthma in children.

Objective:To establish a new classification system for distal clavicle fracture and evaluate its clinical effectiveness.Methods:A retrospective case series study was conducted to analyze the clinical data of 101 patients with distal clavicle fracture admitted to First Affiliated Hospital of Nanjing Medical University from January 2015 to March 2022, including 57 males and 44 females, aged 19-86 years [(53.8±14.0)years]. Before treatment, patients were routinely subjected to bilateral anteroposterior radiography of the shoulder joints to measure the length of the fractured fragments, coracoclavicular distance, and acromioclavicular distance. According to the correlation between the location of the fracture line and the insertion of the coracoclavicular ligament, distal clavicle fracture was divided into three types: type I, with the fracture line lateral to the coracoclavicular ligament region; type II, with the fracture line in the coracoclavicular ligament region; type III, with the fracture line medial to the coracoclavicular ligament region. According to the injury severity of the coracoclavicular ligament and acromioclavicular ligament, type I was further subdivided into type IA, IB, IC and ID, and type II fracture was further subdivided into type IIA, IIB, IIC, IID and IIE. All the 101 patients were classified and randomly reclassified at an interval of 3 months by 10 senior and 10 junior shoulder surgeons according to the new classification method. Kappa coefficients were used to evaluate the inter- and intra-observer consistency of the new classification. Fifty-two patients with stable fracture (types IA, IB, IIC, and IID) were treated non-surgically, while 49 patients with unstable fracture (types IC, ID, IIA, IIB, IIE, and III) were treated surgically, including 26 patients with anatomic coracoclavicular ligament reconstruction, 9 with locking plate fixation, 8 with clavicle hook plate fixation, 4 with anatomic coracoclavicular ligament reconstruction combined with locking plate fixation, and 2 with anatomic coracoclavicular ligament reconstruction combined with tension screw fixation. The patients were assessed using the visual analogue scale (VAS) and Constant-Murley shoulder score before treatment and at 3, 6, 12, and 18 months after treatment. The coracoclavicular distance and acromioclavicular distance on the anteroposterior radiographs of the healthy and affected shoulder joints were measured at 3, 6, 12, and 18 months after treatment, and fracture healing time and complications were observed.Results:The length of the fractured fragments was 12.9 (9.7, 17.6)mm in patients with type I fracture, 24.7 (21.8, 27.8)mm in patients with type II fracture, and 43.6 (41.2, 46.9)mm in patients with type III fracture ( P<0.01). There were no significant differences in the coracoclavicular distance and acromioclavicular distance of the affected and healthy shoulders among the patients with types IA, IB, IIC, IID, and III fracture ( P>0.05); For the patients with types IC, IIA, IIB and IIE fracture, the coracoclavicular distance of the affected shoulder was significantly increased compared with that of the healthy shoulder ( P<0.01), while there was no significant difference in the acromioclavicular distance of the affected and healthy shoulders ( P>0.05). Both of the inter- and intra-observer consistency of the new classification was good. The inter- and intra-observer Kappa values were 0.69 and 0.71 respectively among the senior shoulder surgeons, and 0.61 and 0.64 respectively among the junior shoulder surgeons. All the patients were followed up for 18-104 months [28(23, 32)months]. At 3, 6, 12 and 18 months after treatment, the VAS scores of non-surgical patients were 3(2, 3)points, 2(1, 2)points, 1(0, 1)points and 0(0, 1)points respectively, significantly decreased compared with 6(5, 6)points before treatment ( P<0.01); the VAS scores of surgical patients were 3(2, 3)points, 2(1, 2)points, 1(1, 1)points and 0(0, 1)points respectively, significantly decreased compared with 6(5, 7)points before treatment ( P<0.01); the Constant-Murley shoulder scores of non-surgical patients were (76.6±5.3)points, (84.3±5.0)points, (88.4±4.0)points and (91.9±3.8)points respectively, significantly higher than (42.7±5.2)points before treatment ( P<0.01); the Constant-Murley shoulder scores of surgical patients were (77.4±4.6)points, (84.4±4.7)points, (87.6±3.7)points and (91.7±4.0)points respectively, significantly higher than (42.8±5.3)points before treatment ( P<0.01). At 3, 6, 12 and 18 months after treatment, the coracoclavicular distance of the affected shoulder in non-surgical patients was not significantly different from that before treatment ( P>0.05), while the acromioclavicular distance of the affected shoulder in surgical patients was significantly reduced compared with that before treatment ( P<0.01). There were no significant differences in the coracoclavicular distance of the healthy shoulder or bilateral acromioclavicular distance in non-surgical and surgical patients at 3, 6, 12, and 18 months after treatment compared with those before treatment ( P>0.05). Fractures were healed within 12 months after treatment in all the patients, without dislocation or subluxation of the acromioclavicular joint, internal fixation failure or internal fixator breakage. Eight patients treated with clavicular hook plate fixation had shoulder pain associated with limited mobility after operation, and all underwent a second operation to remove the clavicular hook plate at 12 months after operation. Conclusions:The new classification system for distal clavicle fracture is established, which comprehensively considers the position of the fracture line, injury of the coracoclavicular and acromioclavicular ligaments, and fracture stability. The new classification system exhibits good inter- and intra- observer consistency, and the effectiveness of its preliminary clinical application is satisfactory.

Objective:To analyze the main active components and potential molecular mechanism of Yishen Tongluo Prescrip-tion(YTP)in the treatment of male infertility based on network pharmacological technology.Methods:We searched and sorted the main active components of YTP and their individual potential targets in the databases of Systematic Pharmacology of Traditional Chinese Medicine(TCM)and Bioinformatics Analysis Tool of the Molecular Mechanism of TCM,and screened the targets related to male infer-tility diseases in the databases of Genecards,DisGeNET and OMIM.We made a Venn diagram by intersecting the predicted targets of YTP and those of male infertility diseases,constructed visualized networks for the association of the intersection targets and protein-pro-tein interaction(PPI)using the Cytoscape software and STRING platform respectively,and conducted gene ontology(GO)and KEGG enrichment analyses using the DAVID database and R language"Cluster Profiler"software package respectively.Results:A total of 99 active components,250 targets of YTP,4 397 targets of male infertility and 127 common targets were identified.GO analysis re-vealed that the biological processes of the common targets mainly included transcriptional regulation of RNA polymerase promoter Ⅱ,regulation of gene expressions,regulation of apoptosis,responses to estrogen,and cell responses to hypoxia.KEGG analysis showed significant enrichment of the common targets in the estrogen signaling pathway,cell apoptosis pathway,AGE-RAGE signaling pathway in diabetic complications,and TNF signaling pathway.Conclusion:Through network pharmacology,we identified the main active components of YTP and its multi-target and multi-pathway mechanism in the treatment of male infertility,which has paved the ground for animal and cell experiments in verifying the action mechanism of YTP on male infertility.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.
