Achondroplasia (ACH) is a common inherited skeletal dysplasia (inherited dwarfism) that compromises quality of life across the lifespan. In 2021, vosoritide became the first approved precision therapy for ACH and is now available in more than 40 countries. Compared with prior symptomatic measures, vosoritide has demonstrated favorable efficacy and a reassuring safety profile. Nevertheless, existing international ACH guidelines largely emphasize complication management and symptomatic care, and there is no unified consensus on pharmacologic therapy. To address this gap, an international expert group developed the International Consensus Guidelines for the Implementation and Monitoring of Vosoritide Therapy in Patients with Achondroplasia providing systematic recommendations that span the continuum of care - from initial patient contact and pre-treatment assessment to medication counseling, injection training, and long-term outcome monitoring. These recommendations complement and refine current management and nursing protocols for individuals with ACH and offer practical guidance for clinicians across diverse regions. This article highlights key elements of the guideline to provide evidence-based support and clinical direction for healthcare professionals in China treating children with ACH using vosoritide.

BACKGROUND:Hippocampal injury caused by aortic coarctation has been poorly studied,and combined detection of tumor necrosis factor α,nuclear factor κB and ionized calcium binding adaptor molecule-1 expression in aortic dissection has not been reported.OBJECTIVE:To observe histomorphologic changes in the hippocampus of a mouse model of aortic dissection and investigate the expression and significance of tumor necrosis factor alpha,nuclear factor kappaB and ionized calcium binding adaptor molecule-1 in the hippocampus of aortic dissection mice.METHODS:Sixteen healthy 3-week-old male C57BL/6 mice were randomly divided into two groups:control group and aortic dissection group,with eight mice in each group.In the aortic dissection group,mice were given β-aminopropionitrile monofumarate as drinking water for 4 weeks,and the angiotensin Ⅱ microinfiltration pump was then implanted to establish an animal model of aortic dissection.Mice in the control group were given normal diet and water.After the model was established,the maximum diameter of the ascending aorta was measured,hematoxylin-eosin staining and EVG staining were performed to evaluate the model formation rate,and the levels of inflammatory factors tumor necrosis factor α and interleukin 6 in serum were detected by enzyme-linked immunosorbent assay.The hippocampus was dissected and stained with hematoxylin-eosin to observe the pathological changes of the hippocampus in brain sections.The protein expression of tumor necrosis factor α,nuclear factor κB and ionized calcium binding adaptor molecule-1 was detected by western blot analysis.RESULTS AND CONCLUSION:(1)Compared with the control group,the maximum diameter of the ascending aorta in the aortic dissection group was significantly enlarged.(2)Hematoxylin-eosin staining of the aorta showed obvious thickening of the middle aorta and destruction and disorder of the aortic wall structure in mice.Neurons in the CA1 and CA3 regions of mice were sparsely arranged,reduced in size,and showed pyknosis with deeply stained nuclei.(3)Serum levels of inflammatory factors tumor necrosis factor α and interleukin 6 were increased in the aortic dissection group compared with the control group(P＜0.01).(4)The expression levels of tumor necrosis factor α,nuclear factor κB,phosphorylated nuclear factor κB,and ionized calcium binding adaptor molecule-1 in the hippocampus were increased in the aortic dissection group compared with the control group(P＜0.05).To conclude,microglial activation and increased expression of tumor necrosis factor α and nuclear factor κB may be involved in hippocampal neuron injury in aortic dissection mice.

Liver cancer is one of the most common malignant tumors in the digestive system and ranks sixth among newly diagnosed malignant tumors worldwide. Transforming growth factor-β （TGF-β） regulates cell differentiation， proliferation， apoptosis， and other physiological and pathological mechanisms and exerts cancer-suppressive and pro-cancerous dual effects in the process of tumor development. In recent years， with the continuous exploration of the mechanism of liver cancer， it has been found that the conversion of the cancer-suppressive effect into a pro-cancerous effect of this pathway plays a key role in the development of liver cancer. Traditional Chinese medicine （TCM） provides a unique perspective for the classification， diagnosis， and treatment of liver cancer with its comprehensive regulatory effects of multi-components， multi-targets， and multi-pathways. This paper summarized that the cancer-suppressive mechanisms of the TGF-β signaling pathway included promoting cancer cell cycle arrest， apoptosis， autophagy， et al， while the pro-cancerous mechanisms included promoting cancer cell proliferation， invasion and metastasis， immunosuppression， angiogenesis， et al. The TCM compounds intervening this pathway were sorted out， including Jianpi Huayu compound， Fuyang Baoyuan compound， Yipi Yanggan compound， Fuzheng Jiedu compound， compound Astragalus and Salvia， Biejia Jianwan， Dahuang Zhechong pill， and Qingxiang powder. The single TCMs mainly included Schizocapsa plantaginea， Dendrobii Caulis， Gleditsia sinensis， and Dracaena cochinchinensis. The active ingredients of TCM are mainly concentrated on flavonoids， alkaloids， glycosides， phenolics， terpenoids， polysaccharides， and other kinds of compounds. At the same time， it summarized that the liver cancer inhibition mechanism of TCM by regulating this pathway mainly included promoting apoptosis of liver cancer cells， blocking the cell cycle， and inhibiting liver cancer cell proliferation， migration， invasion， angiogenesis， immune escape， etc. The mechanism aims to give full play to the advantages of TCM and precisely regulate the TGF-β signal， thereby exerting positive anti-tumor effects， opening up a new direction for the precise targeted treatment of liver cancer， and providing a scientific basis and a new strategy for the application of TCM in the treatment of liver cancer.

ObjectiveTo investigate the effects of atorvastatin （ATV） on the proliferation and differentiation of rat bone marrow mesenchymal stem cells （BMSCs）， periodontal ligament stem cells （PDLSCs）， and dental pulp stem cells （DPSCs） in vitro， and to validate the regulatory effect of ATV on periodontal bone formation and tooth movement using a rat orthodontic tooth movement （OTM） model. MethodsThe effects of ATV on the proliferation and osteogenic/odontogenic differentiation of rat BMSCs， PDLSCs， and DPSCs were assessed in vitro. CCK-8 assay was used to detect the proliferation of the three types of cells. Alkaline phosphatase （ALP） staining and Alizarin Red staining were employed to evaluate osteogenic differentiation capacity. Western blot was used to detect the expression of osteogenesis-related proteins ［collagen type I （COL-I）， Runt-related transcription factor 2 （Runx2）， bone morphogenetic protein-2 （BMP-2）， osteocalcin （OCN）］ and the odontogenesis-related protein dentin sialophosphoprotein （DSPP） in BMSCs， PDLSCs and DPSCs. An OTM rat model was established， with rats randomly assigned to an ATV gavage group and a control group. The ATV gavage group received daily oral administration of ATV at a dose of 20 mg/kg， while the control group received an equal volume of solvent by gavage. Tooth movement distance was measured via Micro-CT on days 7， 14， and 21. Histomorphology of periodontal tissues was observed using Hematoxylin and Eosin （HE） staining and Masson staining. The gene and protein expression levels of osteogenic markers （BMP-2， Runx2， OCN） on the tension side of the first molar were detected by qRT-PCR and immunohistochemistry， respectively. ResultsATV at concentrations of 1×10⁻⁶ mol/L and 1×10⁻⁷ mol/L significantly promoted the proliferation and osteogenic/odontogenic differentiation of BMSCs， PDLSCs， and DPSCs， manifested as enhanced ALP activity， increased mineralized nodule formation， and up-regulated expression of osteogenic/odontogenic proteins COL-I， Runx2， BMP-2， OCN， and DSPP （P<0.001）. In the OTM model， compared with the control group， the ATV gavage group showed a significant reduction in tooth movement distance （P<0.05）， enhanced osteogenic activity in periodontal tissues， and significantly increased gene （P<0.001） and protein （P<0.05） expression of BMP-2， Runx2， and OCN on the tension side of the first molar. ConclusionATV enhances periodontal osteogenesis by promoting osteogenic/dentinogenic differentiation， thus inhibiting tooth movement.

ObjectiveZheng’s San Qi San (ZSQS) power, a classic traditional Chinese medicine (TCM) formula, is used for treating soft tissue injuries involving muscles, tendons, and ligaments. However, its underlying therapeutic mechanisms remain unclear. This study aimed to screen and identify pharmaceutically active ingredients and their candidate biomolecule targets, and further elucidate the molecular mechanism of ZSQS in the treatment of skeletal muscle injury. MethodsNetwork pharmacology was employed to construct “ZSQS-component-target”, “protein-protein interaction (PPI)” and “active ingredient-core protein-pathway” networks to predict the key active ingredients and potential core targets of ZSQS for skeletal muscle injury. The predicted results were then validated via microarray data from the GEO database. Molecular docking was then performed to assess the binding ability between the screened active ingredients of ZSQS and the candidate core targets. Moreover, liquid chromatography-mass spectrometry (LC-MS) was used for qualitative and quantitative analysis to verify the active components of the drug and ZSQS serum. Finally, an animal model of eccentric exercise-induced skeletal muscle injury and a myotube cell model of oxidative stress-induced injury were established to validate the effects of ZSQS and its interventional effects on the biological functions of critical targets, thereby demonstrating the potential therapeutic mechanism of ZSQS. ResultsAmong the 111 active components identified in ZSQS and their corresponding 204 targets related to the skeletal muscle injury repair process, 14 core targets (including AKT1) and 4 core active components (quercetin, luteolin, kaempferol, and β‑sitosterol) were screened out, while the corresponding metabolites of quercetin, luteolin and kaempferol were detected in the ZSQS serum. Among these targets, 5 candidate genes (IL-6, CASP3, HIF1A, STAT3, and JUN) overlapped with the differential expression screening results with GEO data, and IL-6 was confirmed to be enriched in the PI3K/AKT pathway. Combined with the prediction results of the AKT expression levels, these findings suggest that the phosphorylation level of AKT1 plays a core role in the therapeutic mechanism of ZSQS. Molecular docking analysis further revealed that the PH domain of AKT1 had high binding energy with all 4 core active components, as verified by LC-MS. Finally, animal model studies have shown the promoting effect of ZSQS administration on skeletal muscle injury repair and its possible antioxidant damage mechanism. Cell model studies further demonstrated that ZSQS-containing serum, core active ingredient combination therapy, and quercetin monomer could increase the phosphorylation level of AKT, promote the nuclear translocation of Nrf2, upregulate the expression of downstream antioxidant enzymes (SOD, GPx, and GR), and inhibit the expression of inflammatory factors (IL-6 and TNF-α), thereby alleviating oxidative stress and the inflammatory response. ConclusionZSQS alleviates skeletal muscle injury mainly by activating the AKT/Nrf2 signaling pathway, enhancing cellular antioxidant and anti-inflammatory capabilities. The results of this study provide a scientific basis for the clinical application and modernized development of ZSQS.

This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

[Purpose]To analyze the incidence and mortality of lung cancer in Zhejiang cancer regi-stration areas in 2021 and trends from 2000 to 2021.[Methods]Using data from Zhejiang cancer registration areas from 2000 to 2021,the crude rate,age-standardized rate by Chinese standard population(ASRC)and the world standard population(ASRW),and composition ratio were calcu-lated to describe the incidence and mortality in 2021.Joinpoint regression was employed to ana-lyze temporal trends over the 22 years,calculating the annual percentage change(APC),average annual percentage change(AAPC),and their 95％confidence intervals(CI).[Results]The crude incidence rate of lung cancer in 2021 was 128.58/105,with an ASRC of 68.74/105,ac-counting for 24.22％of all cancers;the crude mortality rate was 51.55/105,with an ASRC of 21.58/105,constituting 27.98％of all cancer deaths.Both crude incidence rate(AAPC=5.73％,P＜0.001)and ASIRC(AAPC=4.14％,P＜0.001)of lung cancer showed significant increasing trends from 2000 to 2021.The crude mortality rate increased slowly(AAPC=1.76％,P＜0.001),while the ASMRC(AAPC=-0.40％,P=0.035)exhibited a modest decline.The increase in incidence was more pronounced in females than males,though no statistically significant difference was observed in mortality trends.The incidence rates in urban and rural areas showed similar growth trends;the crude mortality rate in rural areas was growing significantly faster than that in urban areas,and the decline in the ASRC was only statistically significant in urban areas.The incidence rate was in-creasing in all age groups.The mortality rate was declining among younger people(＜65 years old).The age group of 15～44 years old demonstrated a greater increase in incidence and a sharper decline in mortality than those aged 45 years old and above.[Conclusion]From 2000 to 2021,Zhejiang Province experienced a marked rise in lung cancer incidence with escalating disease burden.Despite severe population aging,ASRC of mortality declined steadily,reflecting effective prevention and control measures.

OBJECTIVE To investigate the distribution of Candida and predict the detection trend in the southern and northern campuses of Affiliated Hospital of Jiangnan University,Wuxi,between 2021 and 2024.METHODS A total of 27 056 patients with common Candida infections from the southern and northern campuses of Affiliated Hospital of Jiangnan University between 2021 and 2024 were selected to analyze the distribution of Candida species and predict the detection trend.RESULTS Among the 27 056 patients,there were 11 061 males and 15 995 fe-males,aged from 1 to 101 years,with a median age of 68 years.Over the past four years,the top five most com-monly detected Candida species in the hospital were Candida albicans,Candida glabrata,Candida tropicalis,Candida parapsilosis and Candida krusei.Statistically significant differences were found in infection characteris-tics among patients with C.albicans and C.glabrata in terms of gender,age,specimen source and related diseases(P＜0.05).From 2021 to 2024,the number of detected cases declined in 2022 and then rebounded(P＜0.001).Among the detected patients,those aged 70 and above accounted for the highest proportion.Regarding the distribution of specific diseases,the top three were vaginitis(4 176 cases,15.43％),bacterial pneumonia(1 842 cases,6.81％)and cancer(1 279 cases,4.73％).Patients with vaginitis were mainly infected with C.albicans,while patients with bacterial pneumonia were predominantly infected with C.albicans and C.glabrata.The LSTM model showed a good fit to the training set,with an root-mean-square error(RMSE)of 145.03 and an mean absolute error(MAE)of 131.19.Model predictions indicated that the number of patients with Candida in-fections in the hospital would remain low from Jan.to May 2025,which was basically consistent with actual clini-cal observations(RMSE=94.71,MAE=84.00).CONCLUSIONS The common diseases associated with Candi-da infections in the hospital include vaginitis,bacterial pneumonia and cancer.C.albicans and C.glabrata are the main pathogenic species,and the infection situation is relatively severe.The LSTM model performs well in short-term prediction and dynamic analysis of Candida detection trends.
