Objective To investigate the prescription patterns and potential therapeutic mechanisms of traditional Chinese medicine(TCM)in treating laryngopharyngeal reflux disease(LPRD)based on data mining and network pharmacology.Methods The clinical data from 1 016 LPRD patients treated at the Guangdong Provincial Hospital of Chinese Medicine between February 1,2012,and December 30,2023 were collected.Frequency analysis,property and flavor analysis,meridian tropism analysis,efficacy classification,association rule mining,and cluster analysis were performed on the effective TCM prescriptions to identify medication rules.Core herbs were screened,and their therapeutic mechanisms were explored using network pharmacology.Results A total of 1 976 prescriptions involving 139 medicinals(23 644 medicinal frequencies)were analyzed.The top five most frequently-used medicinals were Glycyrrhizae Radix et Rhizoma(Gancao),Poria(Fuling),Citri Reticulatae Pericarpium(Chenpi),Bombyx Batryticatus(Jiangcan),and Galli Gigerii Endothelium Corneum(Jineijin).The herbs predominantly exhibited sweet flavor and neutral property,with a primary affinity for the lung meridian.The most common therapeutic categories were deficiency-tonifying herbs and phlegm-resolving herbs.The herb combination"Gancao-Chenpi-Fuling"was identified as the core prescription for LPRD.Network pharmacology analysis of this combination revealed 11 shared targets between the core herbs and LPRD,including three key targets.The core herbs may alleviate LPRD by modulating the interleukin-17(IL-17)signaling pathway,tumor necrosis factor(TNF)signaling pathway,and cancer-related pathways.Conclusion TCM treatment for LPRD should primarily target the lung,and employs herbs with mild-sweet properties and tonifying effects,supplemented by phlegm-resolving herbs.The core combination"Gancao-Chenpi-Fuling"may exert therapeutic effects by regulating key targets such as IL-1B,TNF,and IL-6,thereby modulating the IL-17 signaling pathway,TNF signaling pathway,and cancer-related pathways to mitigate inflammatory responses in LPRD.

Chronic kidney disease(CKD)is a chronic renal structural and functional disorder caused by multiple causes(history of kidney injury>3 months),with complex etiology and high inci-dence,which will eventually lead to end-stage re-nal disease(ESRD).Common chronic kidney diseas-es include diabetic nephropathy,polycystic ne-phropathy,nephrogenic diabetes insipidus and re-nal fibrosis.At present,there is still a lack of effec-tive specific treatment for chronic kidney disease.The Apelin system is an endogenous physiological regulator.Studies have shown that Apelin is in-volved in the occurrence and development of the above diseases mainly through the regulation of kidney body fluids and blood vessels,and the regu-lation of kidney glucose and lipid metabolism and immunity.This article aims to review the role of Apelin in chronic kidney diseases in recent years,and provide ideas for the treatment and drug de-velopment of kidney diseases with Apelin as a new target.

Immune-related kidney disease is one of the causes of end-stage renal disease and an important disease type that threatens public health. Farnesoid X receptor (FXR) is a nuclear receptor activated by bile acids, involved in regulating gene expression related to bile acid, lipid, and glucose metabolism. In recent years, the role of FXR in renal immune regulation has received attention. FXR participates in the occurrence and development of immune-related kidney diseases by regulating the differentiation, polarization, activation, recruitment, adhesion, infiltration, and cytokine release of immune cells such as macrophages, dendritic cells, natural killer cells, T lymphocytes, and B lymphocytes. This article reviews renal immune-regulatory mechanisms of FXR in recent years and its potential role in immune-related kidney diseases, to provide a theoretical basis for the prevention and treatment of immune-related kidney diseases targeting FXR.

Objective:To summarize the clinical phenotypes and genetic characteristics of Noonan syndrome-like disorder with loose anagen hair 2 (NSLH2) caused by PPP1CB variants. Methods:A case summary.Clinical data, laboratory findings, and imaging studies were collected from a patient with NSLH2 treated at Guangdong Women and Children Hospital in January 2024.Genomic DNA was extracted from the proband and his parents for whole-exome sequencing, with pathogenic variants verified by Sanger sequencing.Literature review was conducted to analyze clinical phenotypes, genetic features, and management approaches in NSLH2.Results:The patient manifested short stature, developmental delay, distinctive facial features, sparse eyebrows, slow hair growth, coarse hair texture, and hypotrichosis.Whole-exome sequencing identified a de novo heterozygous PPP1CB variant (c.146C>G, p.Pro49Arg).Literature review identified 26 reported cases (including this one), with cardinal features including developmental delay, impaired hair growth, abnormal hair texture, characteristic facies, congenital heart disease, short stature, and central nervous system abnormalities. Conclusions:NSLH2 is an autosomal dominant disorder caused by PPP1CB variants with characteristic manifestations.Genetic testing should be considered for children presenting with distinctive facies, developmental delay, impaired hair growth, and abnormal hair texture to establish a definitive diagnosis.

Objective　To explore the application of time series models based on meteorological factors in the population density of Aedes albopictus in Hainan Province, and to provide a scientific basis for the prevention and control of dengue fever in Hainan Province. Methods　The density of Aedes albopictus in different habitats in 18 cities and counties of Hainan Province from 2017 to 2022 was monitored monthly using the double-mosquito net trapping index and the Breteau index. Mann-Kendall trend test was used to analyze the temporal trends of the two density indices; Spearman's correlation analysis was employed to assess the correlation strength between each meteorological factor and the two indexes, eliminating unrelated variables, and further selecting the final variables through the full-subset regression method. Three time-series models were constructed for the two density indices, with root mean square error (RMSE), mean absolute error (MAE), and other accuracy metrics used to determine the optimal model; predictions for the density indices for 2023-2024 were made. All statistical analyses were performed in R (4.3.1). Results　The net trapping and Breteau indices showed an overall decrease over the years (Z-values of Mann-Kendall trend test were -6.15 and -4.03, respectively, and P<0.05). The meteorological factor most strongly associated with the trap index was the monthly average minimum temperature; monthly mean minimum temperature and monthly mean relative humidity were strongly correlated with the Breteau index. Based on various evaluation indicators, the multivariate time series model demonstrated the highest accuracy. The study predicts one to two peaks in both the trap index and Breteau Index for the years 2023 and 2024, with peak periods occurring between June to September and May to September, respectively. The predicted value for 2023 aligns with the measured value, demonstrating outstanding predictive accuracy. Conclusions　This study has introduced meteorological factors into the seasonal time series model, allowing for more accurate predictions of the density of Aedes albopictus in Hainan Province from 2023 to 2024, providing a model framework for the prevention and control of dengue fever in Hainan Province.

Objective To explore the safety and efficacy of neoadjuvant chemotherapy(NAC)combined with immunotherapy before radical cystectomy plus pelvic lymph nodes dissection(RC-PLND)for muscle-invasive bladder cancer(MIBC).Methods The clinical data of 101 patients with MIBC who underwent neoadjuvant therapy followed by RC-PLND in the Department of Urology,the First Affiliated Hospital of Xi'an Jiaotong University during Jan.2019 and Dec.2023 were retrospectively analyzed,including 71 patients(70.3％)who received NAC(NAC group)and 30(29.7％)who received NAC combined with immunotherapy(NAC combine immunotherapy group).The clinical and pathological data and adverse events during neoadjuvant therapy were compared.Logistic regression analysis was used to explore the independent predictors of pathological complete response(pCR)and pathological partial response(pPR).Results There were no significant differences in the baseline data between the two groups(P＞0.05).However,the proportion of multiple tumors in patients receiving NAC before surgery was significantly higher than that in the NAC combined immunotherapy group(69.0％vs.46.7％,P=0.034).Compared with NAC group,NAC combined with immunotherapy group had significantly improved rate of pathological downstaging and pPR(60.6％vs.83.3％,P=0.026;45.1％vs.70.0％,P=0.022).Furthermore,the rate of pCR in patients undergoing NAC combined immunotherapy was higher than those undergoing NAC,but the difference was not significant(53.3％vs.33.8％,P=0.067).Logistic regression analysis revealed that clinical T-stage and tumor diameter were independent predictors of pCR and pPR(P＜0.05).In addition,the most common adverse events during neoadjuvant therapy were anemia,decreased white blood cells,nausea,and vomiting,but most of them were grade 1-2 and could be relieved through symptomatic treatment.Conclusion NAC combined with immunotherapy is safe and effective,which can improve the rate of pathological downstaging,pPR and pCR,without increasing the incidence of adverse reactions.

Objective:To analyze the effects of a novel type of polydopamine (PDA)-coated porous titanium alloy scaffolds loaded with zoledronic acid-gelatin nanoparticles (ZOL-GNPs) for topical sustained drug release on osteoclasts in vitro. Methods:After porous titanium alloy scaffolds were fabricated using electron beam melting technique and ZOL-GNPs with different ZOL concentrations (0, 1, 10, 50, 100, 500 μmol/L) were prepared by desolvation method, PDA-coated porous titanium alloy scaffolds loaded with ZOL-GNPs were constructed by combining the two. The characteristics of the scaffolds were analyzed. The biomechanics of 3 different scaffolds (bare porous titanium alloy scaffolds, PDA-coated porous titanium alloy scaffolds, and PDA-coated porous titanium alloy scaffolds loaded with ZOL-GNPs) were investigated. Drug release detection was carried out by high performance liquid chromatography on the 1st, 4th, 7th, 14th, 21st, and 28th days respectively. The osteoclasts were inoculated into the novel scaffolds with different ZOL concentrations. The expression of osteoclast-related genes was detected by real-time quantitative (RT)-polymerase chain reaction (PCR); the expression of osteoclast-related proteins was detected by Western-blot.Results:The PDA-coated porous titanium alloy scaffolds loaded with ZOL-GNPs were successfully constructed. Electron microscope scanning showed that the GNPs were well spheroidized, smooth in surface, and uniformly dispersed, with a particle size of (243.6±63.4) nm. The ZOL-GNPs were uniformly compounded on the surface and in the pores of the scaffolds, and the spheres were regular in shape with no adhesion. The biomechanical experiments showed that the elastic moduli of the porous titanium alloy scaffolds under 3 different conditions were (1.81±0.12) GPa, (1.80±0.23) GPa and (1.81±0.15) GPa, showing no significant difference ( P> 0.05). The drug release percentage in the porous titanium alloy scaffolds was obviously high on the first day, and increased gradually and slowly in the subsequent 27 days. In the scaffolds with a low concentration ZOL, more osteoclasts adhered and proliferated; in the 50 μmol/L scaffolds, spheroid cells appeared; the spheroid cells increased and even apoptosis occurred with an increase in the ZOL concentration. RT-PCR showed that the expression of Ctsk gene and TRAP gene increased with the increased ZOL concentration, peaked in the 50 μmol/L scaffolds, and then decreased with the increased concentration, showing statistically significant differences ( P < 0.05). Western-blot showed that the expression pattern of Ctsk and TRAP was similar to that of their related genes. Conclusions:The novel PDA-coated porous titanium alloy scaffolds loaded with ZOL-GNPs demonstrate good mechanical properties and an anti-osteoporosis effect via their topical sustained drug release. The scaffolds with a ZOL concentration of 50 μmol/L may exert the best effect on inhibition of osteoclasts.
