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.

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 explore the current status of medication literacy among urban elderly patients with chronic diseases in Anhui Province,aiming to reveal the factors influencing their medication literacy,and to propose targeted measures for improvement.Methods This research involved 381 participants aged 60 and above.It was conducted in Anhui province between December,2022 and January,2023,with data collected through face-to-face interviews by pharmacists.Single-factor analysis and ordinal multi-class logistic regression analysis were conducted to determine factors affecting medication literacy.Results Medication literacy cognition and medication literacy behavior were rated as good among urban older adults in Anhui province of the 294 valid questionnaires.Those who did not understood package insert exhibited significantly lower medication literacy behavior than those who fully understood[estimate=-1.224,95%CI=(-2.130,-0.317),P<0.01].Elderly patients with chronic diseases faced issues such as an inability to read or understand drug instructions in the investigation.90.48%of elderly patients with chronic diseases never heard or seldom heard of medication guidance services.Conclusion Medication literacy among urban elderly patients with chronic diseases is generally good in Anhui province.The ability to understood drug instructions significantly influenced the medication literacy of urban elderly patients with chronic diseases.Modifying the drug instructions to meet the reading needs of the elderly patients with chronic diseases and developing pharmaceutical care could effectively enhance rational drug use among this demographic.

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.

Novel therapeutic approaches targeting key genes and regulatory molecules of hepatocellular carcinoma (HCC) have gradually been carried out in clinical practice. Hypoxia-inducible factor (HIF), as a critical factor for hepatocellular carcinoma cells to adapt to the hypoxic microenvironment, mediates changes in the transcription of many genes. HIF has a wide range of target genes and can promote metabolic reprogramming, angiogenesis, invasion and metastasis, and immune escape of cancer cells by regulating various signaling pathways. Hypoxia-inducible factor 1α (HIF-1α), as the main member of the HIF family, can provide new ideas and insights for exploring potential targets for HCC treatment.

Objective To analyze the hepatitis B virus infection with extreme reduction of cholinesterase(CHE)not caused by liver synthesis dysfunction,and to explore its clinical significance.Methods The clinical data of 2 rare cases hospitalized in the 3rd people's hospital of Kunming in July 2021 and February 2022,including liver function,coagulation function,hepatitis B markers,hepatitis B virus volume,and whole exon sequencing,were collected and analyzed,and literature was reviewed.Results CHE was extremely reduced in 2 patients with HBV infection,liver synthesis function was good,and whole exon sequencing showed the presence of butyrylcholinesterase(BCHE)gene mutation.Conclusion The extremely low CHE in this case is not due to liver function disorder.Exon sequencing detected mutations in the BCHE gene in two patients.Screening for BCHE mutations may be necessary in patients with extremely low cholinesterase levels not due to liver dysfunction.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

[Objective]To observe the dynamic changes of serum LH levels in different GnRH-along protocols ,and investigate the relationship between GnRH-adosage and LH levels ,and compare the clinical outcomes among different GnRH-a long protocols.[Methods]In this retrospective study,1.0 mg,0.8 mg,0.375 mg long-acting and 0.1 mg/d,0.05 mg/d short-acting GnRH-a long protocols were included from January to June in 2015 at the Reproductive Medicine Center of the First Affiliated Hospital of Sun Yat-Sen University. Serum LH levels were evaluated from a total of 250 women at the four time points,on the day before gonadotropin stimulation(Gn0),the fourth day of Gn stimulation(Gn4),the seventh day of Gn stimulation(Gn7),and the HCG administration day(HCG day),then the relationship between serum LH levels and the dosage of GnRH-a were analyzed. The number of oocytes retrieved,fertilization rate,good quality embryos rate,blastocyst transferred rate,the number of transferred embryos,implantation rate and clinical pregnancy rate were also compared.[Results]Among the long-acting groups,LH levels in 0.375 mg group were higher than those in 1.0 mg and 0.8 mg groups at the four time points(P<0.05). Total Gn dose,duration of Gnstimualtion and HMG dosage of 1.0 mg protocol and 0.8 mg protocol were significantly higher than those of 0.375 mg group(P < 0.05). In addition,the implantation rate showed an increasing tendency when the level of LH increases(P>0.05). In short-acting groups,the LH levels in 0.05 mg/d protocol were significantly lower than those in the 0.1 mg/d group at Gn0,Gn7 and HCG day(P<0.05). Total Gn dose,du?ration of Gn stimulation and HMG dosage did not show significant difference between 0.05mg and 0.1mg group. What′s more,the im?plantation rate in 0.1 mg/d group was higher than in 0.05 mg/d group(P>0.05).[Conclusion]Among the long-acting groups,the smaller amount of GnRH-a was administrated ,the higher LH levels during ovarian stimulation and implantation rate the patients ob?tained. As to the short-acting groups,the LH level and implantation rate in 0.1 mg/d group is higher than those in 0.05 mg/d group.

Objective To explore the effect of a multimodal electroencephalogram ( EEG) data visualiza-tion system on the motor imagery ability of stroke survivors. Methods Twenty stroke patients were randomly di-vided into an experimental group and a control group, each of 10. Both groups were provided with brain-computer interface-based motor imagery ( MI) training. At the same time, the experimental group was monitored and guided using an online, multimodal EEG data visualization system developed in our department. The classification accuracy ( CA) and event-related desynchronization ( ERD) of the 2 groups′ motor imagery were compared before and after the treatment. Results Before the treatment, no significant differences in the average CA of MI were found be-tween the experiment group (50.92±2.08) and the control group (49.35±4.20)(P>0.05). After the treatment, however, the experimental group′s average CA had increased to (64.52±5.27), significantly higher than that of the control group (51.18±5.02). When the stroke patients imaged affected upper extremity movements, obvious ERD was observed in the α frequency around the bilateral central motor regions of both groups, especially in the experi-mental group, but without significant differences between the two groups. However, no significant changes were found in the ERD of theβwaves of the two groups( P>0.05) . Conclusion The proposed online multimodal elec-troencephalogram data visualization system can help stroke patients imagine movements actively. It is worth sprea-ding in clinical practice.
