OBJECTIVE To explore the hotspots of aging adaptation of drug package inserts， and to provide evidence for the development of aging adaptation of drug package inserts in China. METHODS The relevant English literature on drug package inserts for the elderly published from 2012 to 2022 was retrieved from Web of Science Core Collection； bibliometric analysis was performed by using VOSviewer and CiteSpace software， to explore research hotspots in this field， and summarize obstacles and solutions for the development of this field. RESULTS & CONCLUSIONS This study collected a total of 335 literature related to the aging adaption of drug package inserts， from 819 research institutions in 51 countries （regions）， involving 2 174 authors. The research development of drug package insert adaptation for the elderly has slowed down in the past decade， and developed countries such as the United States and Japan dominate this field. Authors such as Wolf from Northwestern University in the United States， have the largest number of publications（12 literature）. The research focuses in this field include the risk management of medication for the elderly， the updating of medication information for the elderly in drug package inserts， and the understanding and compliance of the elderly with drug package inserts and their influencing factors. The solutions to related obstacles in the development of aging adaption in drug package inserts include improving the visibility and readability of drug package inserts， filling in the information on elderly medication in drug package inserts， and so on. China can learn from the experiences and methods of other countries， conduct investigations into the influencing factors of elderly package inserts and pharmacokinetic studies based on the characteristics of the Chinese population， and improve the safety of medication for elderly patients in multiple dimensions.

AIM:To explore the effect of high aspherical lenticule on controlling low myopia.METHODS: Prospective study. A total of 100 patients aged 7 to 12 years old with low myopia who visited our hospital from May 1 to 31, 2022 were collected. They were divided into two groups with 50 cases in each group according to the wishes of patients. The control group was given single vision glasses after optometry, while the study group was given high aspherical lenticule. The myopia progression(absolute value), axial length(AL)growth, transition rate to moderate myopia, and AL negative growth rate over 6 mo and 1 a were compared between the two groups.RESULTS: The myopia progression and the AL growth of study group was lower than that of the control group after 6 mo and 1 a(all P<0.001).The negative growth rate of AL after 6 mo of treatment was significantly higher than that of the control group(P<0.001). The transition rate to moderate myopia between the two groups was not statistically significant(P=0.62); while the transition rate to moderate myopia in the study group was significantly lower than that in the control group after wearing lens for 1 a(P<0.001), and there was no statistically significant difference in AL negative growth rate between the two groups(P=0.12). Compare with single vision glasses, high aspherical lenticule achieved an 88.2% control rate for low myopia progression over 6mo and a 90.0% control rate of AL growth. The control rate for low myopia to moderate myopia was 66.7%; while the control rate of myopia progression growth was 75.6% after wearing lens for 1a, the control rate of AL growth was 69.2%, and the control rate of the transition rate to moderate myopia was 88.9%.CONCLUSION: For children and adolescents aged 7 to 12 with low myopia, high aspherical lenticule was more effective than single vision glasses in controlling myopia, making it one of the optimal choices for myopia control.

Objective To explore the effects of prohibitin 2(PHB2)on sensitivity of non-small cell lung cancer cell line A549 to erlotinib(Erl)and its potential mechanisms.Methods RACK1-specific small interfering RNA was transfected in A549 cells for knocking-down of PHB2.The effects of PHB2 inhibition on cell proliferation and apop-tosis induced by Erl were observed.The colocalization of microtuble-associated protein light chain 3 alpha(LC3)and mitochondria was visualized by MitoTracker staining and green fluorescent protein-microtuble-associated protein light chain 3 alpha(GFP-LC3)transfection.Cell proliferation was detected by 5-ethynyl-2′-deoxyuridine(EdU)staining.Cell colony formation was evaluated by colony forming assay.Apoptotic index of A549 cells was evaluated by TUNEL.Western blot was used to measure the expressions of PHB2 and LC3Ⅱ.Mitochondrial transmembrane potential,cytochrome c and respiratory chain complexⅠ/Ⅱ/Ⅴactivity were analyzed by the commercially availa-ble kits.Results Compared with the siPHB2 and siCtrl+Erl group,the EdU-positive A549 cells and the number of cell colonies decreased significantly(P＜0.05),while the TUNEL-positive A549 cells increased significantly(P＜0.05)in the siPHB2+Erl group.In addition,compared with the siPHB2 and siCtrl+Erl group,mitochondrial transmembrane potential and respiratory chain complexⅠ/Ⅱ/Ⅴactivity decreased significantly(all P＜0.05)and the levels of cytochrome c increased in mitochondrial fractions(P＜0.05)and decreased in cytosolic fractions(P＜0.05)in the siPHB2+Erl group.Conclusions PHB2 inhibition significantly improves sensitivity of A549 cells to Erl,which may be explained by inhibition of PHB2-mediated mitochondrial autophagy.

OBJECTIVE To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification. METHODS From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR. RESULTS Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis. CONCLUSION This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.

Objective To analyze the differences in aging-related information between Chinese and American drug instruction for common chronic disease in the elderly,and to propose policy recommendations for the aging-related drug instruction in China.Methods Ten common chronic disease treatment drugs for elderly patients were selected,and through the random sampling method,the drug manuals of one domestic manufacturer were randomly selected for each drug by the random number method,and one American drug manual was selected as a sample from the dailymed website,and the information related to elderly people in the various items of the drug manuals was statistically analyzed by using Excel for comparative analysis.The average reading level of the patient version of the U.S.drug instructions was calculated using the Readability Formulas Scoring System;the readability of the Chinese drug instructions was assessed by the Health Education Text Material Suitability Scale.Results Compared with the U.S.drug instruction,the drug instruction for common chronic diseases of the elderly in China were updated less frequently and at a slower pace;the drug instruction with information on medication for elderly patients were fewer than those of the U.S.drug instruction,and the content of the drug instruction was not well documented;and the drug instruction were poorly readable,which was not conducive to the comprehension of the elderly patients.Conclusion China is in urgent need of reforming the aging of drug instructions,and it is recommended that,for chronic disease medications for elderly patients,we should increase the number of clinical trials conducted on the elderly,improve and complete the drug information for the elderly in the drug instructions,and produce"drug instructions for elderly patients"that are suitable for the elderly to read and understand.

Objective To evaluate the status of home medication safety among elderly patients with chronic diseases and analyze its influencing factors in urban and rural areas of Henan Province.Methods Convenient sampling method was adopted.Data was collected through a designed and optimized questionnaire.Pharmacists conducted in-home surveys.Excel and SPSS 26.0 software were used for data analysis.Results A total of 352 valid questionnaires were analyzed.Most respondents were aged 60～70 years,with a female proportion of 56.2%,and 52.0%of them had a junior high school education or lower.The top-ranked chronic diseases were hypertension(62.2%)and hyperlipidemia(33.2%),and 61.1%of patients suffered from multiple chronic diseases.Antipyretic and analgesic drugs were most common in home medicine cabinets(90.1%).The proportion of drugs being stored in accordance with the instructions(46.9%)was slightly low,and 93.8%of the elderly handled expired drugs improperly.Awareness of medication guidance services was low(34.9%).Logistic regression analysis showed that factors such as education level and monthly income had significant effects on the understanding of drug package insert,rational drug storage,proper disposal of expired drugs,and awareness of medication guidance services(P<0.05).Conclusion There are still some potential safety risks in the home medication use of elderly patients with chronic diseases in urban and rural areas of Henan Province.It is necessary to enhance education on drug storage and medication guidance,particularly for low-income and less-educated groups,to improve the safety of home medication use.

Objective:To explore the efficacy of a flat ground exoskeleton robot in improving the walking ability of stroke survivors.Methods:Fifty-eight stroke survivors with mobility difficulties were randomly divided into a robot group ( n=29) and a control group ( n=29). In addition to routine rehabilitation, the control group received conventional walking training, while the robot group underwent exoskeleton robot-assisted gait training. The 30-minute training sessions were held twice a day, 5 days per week for 5 weeks. Before as well as after 2 and 4 weeks of treatment, everyone′s walking ability was tested using the 6-minute walk test (6MWT) and functional ambulation scale (FAC). General lower limb motor function was quantified using the Fugl-Meyer Lower Extremity assessment (FMA-LE). Moreover, gait analysis was conducted before and after 4 weeks of treatment. Results:After 2 and 4 weeks of treatment, the average 6MWT times of both groups were significantly better than before the treatment, with the improvement of the robot group significantly greater than that of the control group after 2 weeks. After 2 and 4 weeks the average FMA-LE and FAC scores of both groups had improved significantly compared with before treatment. After 4 weeks the stride frequency and gait cycle of both groups had improved significantly.Conclusions:Exoskeleton robot-assisted gait training can improve walking ability and lower limb motor function of stroke survivors about as well as conventional walking training.

Objective:To explore the puncture management in hemodialysis patients with difficult new arteriovenous fistula based on the finest evidence-based best practice evidence and evaluate the clinical effects.Methods:A team was formed, according to theoretical framework basing on the evidence of continuous quality improvement model, the best evidence-based interventions were obtained by adopting evidence-based practice. Formulated review indicators, evaluated obstacles and promoting factors in the process of practice, and took corresponding action strategies. From February 2020 to June 2020, 30 patients admitted to the dialysis center of Sir Run Run Shaw Hospital of Zhejiang University were recruited in the baseline review group by convenience sampling method. From September 2020 to January 2021, 30 patients from September 2020 to January 2021 were recruited in the after-effect evaluation group. The baseline review group adopted the original difficult new arteriovenous fistula puncture management scheme, and the after-effect evaluation group adopted the difficult autologous new internal fistula puncture management scheme based on the best evidence. The success rate of one puncture of fistula, the incidence rate of hematoma during puncture and dialysis, the incidence rate of discontinuation of treatment and the compliance with examination indexes were compared in the patients before and after applying for the evidences.Results:Compared with the baseline review group, the success rate of one-time puncture of internal fistula in the aftereffect evaluation group increased from 36.7% (11/30) to 73.3% (22/30), the incidence rate of hematoma during puncture and dialysis were decreased from 33.3%(10/30) to 6.67%(2/30) and 40%(12/30) to 0, the incidence rate of discontinuation of treatment were decreased from 40%(12/30) to3.33% (1/30), the difference was statistically significant ( χ2 values were 6.67-11.88, P<0.05). The implementation rate of review indexes in the aftereffect evaluation group was higher than that in the baseline review group, and the difference was statistically significant ( P<0.05). Conclusions:Evidence-based practice can improve the success rate of difficult new arteriovenous fistula, and reduce the incidence of arteriovenous fistula hematoma, reduce treatment interruption, and better maintain the lifeline of patients.

Objective:To investigate the clinical efficacy of microsurgical resection in primary jugular foramen schwannomas (JFSs).Methods:A retrospective analysis was performed; the clinical data of 58 patients with JFSs treated by microsurgery in Department of Neurosurgery, First Affiliated Hospital of Sun Yat-sen University from May 2012 to June 2021 were collected. Seven patients accepted microsurgery via suboccipital retrosigmoid approach, and 51 patients accepted microsurgery via jugular foramen approach. Fifty-three patients were followed up for 4.5 years (ranged from 0.5-8.5 years); follow-ups included Karnofsky performance status (KPS) scores, postoperative complications, and imaging reexaminations. Results:Fifty patients (86.2%) achieved total tumor resection and 8 (13.8%) subtotal resection. The KPS scores at discharge were 68.6±14.9, which were significantly lower than the preoperative KPS scores (77.6±13.5, t=2.452, P=0.017). During the follow-up, 5 patients(9.4%) had tumor recurrence, and 39 patients (73.6%) had improved symptoms after surgery. One patient (1.9%, modified Samii D type) died of cerebellar hemorrhage and swelling after surgery. The main complications included new/aggravated hoarseness (11/53), cerebrospinal fluid leakage (7/53), new/aggravated dysphagia (5/53), and new facial paralysis (4/53). Conclusion:In microsurgical resection of JFSs, short-term symptoms of the lower cranial nerves may be exacerbated, but long-term results are good.
