Currently, the drug delivery system (DDS) based on nanomaterials has become a hot interdisciplinary research topic. One of the core issues is drug loading and controlled release, in which the key lever is carriers. Vaterite, as an inorganic porous nano-material, is one metastable structure of calcium carbonate, full of micro or nano porous. Recently, vaterite has attracted more and more attention, due to its significant advantages, such as rich resources, easy preparations, low cost, simple loading procedures, good biocompatibility and many other good points. Vaterite, gained from suitable preparation strategies, can not only possess the good drug carrying performance, like high loading capacity and stable loading efficiency, but also improve the drug release ability, showing the better drug delivery effects, such as targeting release, pH sensitive release, photothermal controlled release, magnetic assistant release, optothermal controlled release. At the same time, the vaterite carriers, with good safety itself, can protect proteins, enzymes, or other drugs from degradation or inactivation, help imaging or visualization with loading fluorescent drugs in vitro and in vivo, and play synergistic effects with other therapy approaches, like photodynamic therapy, sonodynamic therapy, and thermochemotherapy. Latterly, some renewed reports in drug loading and controlled release have led to their widespread applications in diverse fields, from cell level to clinical studies. This review introduces the basic characteristics of vaterite and briefly summarizes its research history, followed by synthesis strategies. We subsequently highlight recent developments in drug loading and controlled release, with an emphasis on the advantages, quantity capacity, and comparations. Furthermore, new opportunities for using vaterite in cell level and animal level are detailed. Finally, the possible problems and development trends are discussed.

With the publication of several phase Ⅱ and Ⅲ clinical studies, the multidisciplinary diagnostic and therapeutic strategies for early resectable non-small cell lung cancer (rNSCLC) are rapidly evolving. These studies have elucidated the significant effects of neoadjuvant and adjuvant therapies on improving the prognosis of rNSCLC patients, while also highlighting the urgent need to revise and refine corresponding treatment protocols and clinical pathways. In response, the International Association for the Study of Lung Cancer has assembled a diverse, multidisciplinary international expert panel to evaluate current clinical trials related to rNSCLC and to provide diagnostic, staging, and treatment recommendations for rNSCLC patients in accordance with the 8th edition of the AJCC-UICC staging system. The consensus recommendations titled "Neoadjuvant and adjuvant treatments for early stage resectable non-small cell lung cancer: Consensus recommendations from the International Associationfor the Study of Lung Cancer" outline 20 recommendations, 19 of which received over 85% agreement from the experts. The recommendations indicate that early rNSCLC patients should undergo evaluation by a multidisciplinary team and complete necessary imaging studies. For stage Ⅱ patients, consideration should be given to either adjuvant therapy following surgery or direct neoadjuvant/perioperative treatment, while stage Ⅲ patients are recommended to receive neoadjuvant chemoimmunotherapy followed by surgery. Postoperatively, adjuvant immunotherapy should be considered based on the expression levels of programmed cell death ligand 1, along with testing for other oncogenic driver mutations. For patients with epidermal growth factor receptor or anaplastic lymphoma kinase mutations sensitive to tyrosine kinase inhibitors, corresponding adjuvant targeted therapy is recommended. These recommendations aim to provide personalized and precise treatment strategies for early rNSCLC patients to enhance the efficacy of neoadjuvant and adjuvant therapies. This article provides an in-depth interpretation of these consensus recommendations.

AIM To explore the clinical effects of Supplemented Baihe Gujin Decoction on elderly patients with postoperative pulmonary infection following non-small cell lung cancer surgery.METHODS Ninety-two patients were randomly assigned into control group(46 cases)for 1-week intervention of conventional treatment,and observation group(46 cases)for 1-week intervention of both Supplemented Baihe Gujin Decoction and conventional treatment.The changes in clinical effects,TCM syndrome scores,immune function indices(CD3+,CD4+,CD8+,CD4+/CD8+),inflammatory indices(CRP,PCT,TNF-α),serum indices(sTREM-1,CD40L,NLR)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome scores,CD8+,inflammatory indices,serum indices(P＜0.05),and increased CD3+,CD4+,CD4+/CD8+(P＜0.05),especially for the observation group(except for CD4+,CD8+)(P＜0.05).CONCLUSION For the elderly patients with postoperative pulmonary infection following non-small cell lung cancer surgery,Supplemented Baihe Gujin Decoction can safely and effectively relieve clinical symptoms,enhance immune functions,reduce serum sTREM-1,CD40L levels and NLR,and control inflammatory responses.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

In this paper, two cases of primary familial and congenital polycythemia (PFCP) were reported, and the literature was reviewed. PFCP is a rare autosomal dominant inherited disease caused by a gain-of-function mutation in the EPOR gene, resulting in a loss of negative regulation of erythrocyte proliferation. The two patients were young women with simple polycythemia and clear family history, and identified to carry the truncated mutation c.1316G>A (p.W439*) of EPOR gene. At present, there is no unified treatment plan for PFCP. Currently, there is no standardized treatment for PFCP; management primarily aligns with guidelines for polycythemia vera, focusing on preventing thrombotic complications. This article discusses the clinical features of PFCP, EPOR gene mutations, and their pathogenic mechanisms, while providing diagnostic and therapeutic recommendations based on existing literature.

Objective:To investigate the clinical efficacy of minimally invasive double anchoring combined with percutaneous kyphoplasty (PKP) for Kümmell disease.Methods:The clinical data of 24 patients with Kümmell disease who were treated with minimally invasive double anchoring combined with PKP in Cangzhou People's Hospital from October 2022 to March 2024 were retrospectively analyzed. Among them, there were 2 T 10 vertebrae, 5 T 11 vertebrae, 7 T 12 vertebrae, 6 L 1 vertebrae, and 4 L 2 vertebrae. There were 6 males and 18 females. The average age was 72.05±4.52 years (range, 66-80 years). The bone mineral density T value was -3.41±0.77 (range, -2.5-4.5). The stages of Li's Kümmell disease included 13 cases of stage II and 11 cases of stage III. The operation time, intraoperative blood loss, and volume of bone cement injected were recorded. The vertebral index, vertebral angle and Cobb angle of diseased segment were measured before and after operation. The visual analogue scale (VAS) was used to assess the degree of pain, the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) low back pain scale were used to assess spinal function. The Medical Outcome Study short form 36 item health survey (SF-36) was used to assess the general health status of the patients. The postoperative symptom recovery was evaluated by Odom criteria. Results:The mean operative time of the 24 patients was 35.32±6.86 min, the injected volume of bone cement was 4.39±1.72 ml, and the intraoperative blood loss was 16.56±5.21 ml. All patients were followed up for 10 to 14 months, with an average of 11.7 months. Postoperative CT examination showed that the screw positions were satisfactory, and no loosening or displacement of bone cement mass occurred. On the first day after surgery, the vertebral body index, vertebral body angle and Cobb angle of diseased segment were 77.71%±2.75%, 12.40°±1.53° and 25.77°±4.49°, respectively, which represented significant improvements from the preoperative values of 43.09%±5.66%, 22.12°±2.92° and 46.98°±5.68° before surgery ( P<0.05). At the last follow-up, the values were 76.18%±2.32%, 12.41°±2.53°, 26.14°±4.87°, respectively, which were significantly improved compared with those before surgery ( P<0.05), but there was no statistical significance compared with the first day after surgery ( P>0.05). The VAS, ODI and JOA scores on the first day after surgery were 2.11±0.87 points, 22.46±5.49 points and 27.68±2.45 points, respectively, which were significantly improved compared with those before surgery 7.50±0.98 points, 76.25±8.56 points and 14.96±4.91 points ( P<0.05). At the last follow-up, the values were 2.26±0.88, 23.87±3.25 and 26.58±2.77, respectively, which were significantly improved compared with those before surgery ( P<0.05), and there was no statistical significance compared with the first day after surgery ( P>0.05). All 24 patients completed SF-36 scale assessment, and the results showed that there were statistically significant differences in physiological function, physiological role, physical pain, general health status, social function scores and mental health between the patients before surgery and the last follow-up ( P<0.05), while there were no statistically significant differences in vitality and emotional function ( P>0.05). At the last follow-up, the Odom criteria showed excellent results in 18 cases, good in 4 cases, and fair in 2 cases. Conclusions:The application of minimally invasive double anchoring (single nail fixation) combined with PKP in the treatment of Kümmell disease can effectively prevent the loosening and displacement of bone cement masses, and the fixation effect is satisfactory, which can restore the height of the injured vertebrum, reduce kyphosis and improve spinal function. The clinical symptoms of the patients were significantly improved, and the quality of life was enhanced.

Objective:To investigate the drug resistance of newly diagnosed HIV-1 infected patients in Shanghai and to provide reference value for clinical antiretroviral therapy (ART).Methods:The peripheral venous blood plasma of 196 newly diagnosed HIV-1 infected patients screened according to the inclusion and exclusion criteria at the Shanghai Public Health Clinical Center from April to June 2023 was collected, HIV-1 RNA was extracted, the pol region was amplified by reverse transcription-polymerase chain reaction (RT-PCR) for sequencing, the mutation sites and ART drug resistance were analyzed.Results:The plasma of 196 newly diagnosed HIV-1 infected patients was amplified successfully in 162 cases (amplification success rate was 82.65%). The subtypes consisted of CRF07_BC(51.23%), CRF01_AE (27.78%), and others (6.79%), CRF55_01B (5.56%), B (3.70%), CRF01_AE/B (3.70%) and CRF08_BC (1.23%). The overall transmitted drug resistance rate was 7.41%, the protease inhibitors (PIs), non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs), nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), integrase inhibitors (INSTIs) resistance rates were 3.09%, 3.70%, 0.00% and 0.62%, respectively. The proportion of NNRTIs-related mutation sites in B (66.67%) and CRF55_01B (88.89%) was higher than that in CRF07_BC (13.25%); the proportion of NNRTIs-related mutation sites in CRF55_01B (88.89%) was higher than that in CRF01_AE (22.22%) and other subtypes (18.18%), the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that the probability of PIs-related mutation sites in CRF01_AE/B was 21.71 times that of CRF07_BC[odds ratio ( OR)=21.71, 95% confidence interval ( CI): 3.36-140.27, P=0.001]. Conclusions:The transmitted drug resistance among newly diagnosed HIV-1 infected patients in Shanghai is at the moderate epidemic level, mainly NNRTIs and PIs-related drug resistance, and the INSTIs resistance rate is low, the use of INSTIs in ART regimens should be considered.

Objective:To investigate the effects of Zhibai Dihuang Pills on neurons of cognitive dysfunction in D-galactose (D-gal) model mice.Methods:Totally 60 male mice were divided into four groups using a random number table method: control group, model group, donepezil group, and Zhibai Dihuang Pills group, with 15 mice in each group. Except for the control group, the other groups were subcutaneously injected with D-galactose solution at a dosage of 125 mg/kg once a day for 8 weeks to prepare the aging model. Mice in the donepezil group were intragastrically administered donepezil solution at a dosage of 0.65 mg/kg, and those in the Zhibai Dihuang Pills group were intragastrically administered Zhibai Dihuang Pills solution at a dosage of 1.56 g/kg. The control group was intragastrically administered an equal volume of physiological saline once a day for 8 weeks. The object recognition test and Morris Water Maze were used to assess object recognition memory and spatial learning memory abilities of mice in each group, respectively. Hematoxylin-Eosin (HE) staining and Nissl staining were employed to observe the morphology of neurons in the hippocampal region; Golgi staining was used to observe neuronal dendritic spines; Western Blot was used to detect the protein expression levels of PI3K, p-Akt/Akt, glycogen synthase kinase 3β (GSK3β), postsynaptic density protein-95 (PSD-95), and synaptophysin (SYP) in the hippocampus region; RT-qPCR was performed to detect mRNA expression of PI3K, Akt and GSK3β in the hippocampus region.Results:Compared with the model group, the recognition index in both the donepezil group and the Zhibai Dihuang Pills group increased ( P<0.05), the escape latency was shortened ( P<0.05), the platform crossings times and the target quadrant dwell time increased ( P<0.05), the number of nerve cells in the hippocampal region increased, arranged closely, the number of Nissl bodies increased, the morphology returned to normal, and the density of dendritic spines increased; the protein expressions of PI3K, PSD-95, and SYP in the hippocampal region and the ratio of p-Akt/Akt increased ( P<0.01), the mRNA level of PI3K increased ( P<0.01 or P<0.05), and the protein and mRNA levels of GSK3β decreased ( P<0.01 or P<0.05). Conclusion:Zhibai Dihuang Pills can improve the learning and memory ability and rescue neuronal damage in D-gal model mice, and the mechanism may be related to the activation of PI3K/Akt pathway and the restoration of synaptic connections.
