Objective To study the clinical characteristics and medication patterns of Wangbi Tablets in treating patients with knee osteoarthritis(KOA)in the real world and to analyze the advantages and specific features of Chinese patent medicines in treating advantage disease.Methods A prospective case registry study was conducted,registering 3 000 patients from 30 TCM and Western medicine hospitals across China from April 2019 to December 2021.Data on gender,age,BMI,Chinese medicine staging(CMS),K-L grading,medication duration,VAS score,medical history and combined medication were collected for descriptive analysis.Comparisons were made between different stages and between single-use and combined-use groups.The Apriori algorithm was used for association analysis of combined medications.Results A total of 2 999 patients were included,with 2 063 females(68.79%)and 936 males(31.21%).The average age was(56.89±8.90)years.The average BMI was(23.80±2.88)kg/m2.The proportion of patients in CMS I was 512(17.07%),with a VAS median score of 8,while the proportion of patients in CMS Ⅱ was 2 181(72.73%),with a VAS median score of 6.The proportion of patients in CMS Ⅲ was 306(10.20%),with a VAS median score of 3;316 cases(10.54%)were classified as K-L grade I,2 477 cases(82.59%)as grade Ⅱ,204 cases(6.80%)as grade Ⅲ,and 2 cases(0.07%)as grade Ⅳ.Medication analysis indicated that the single-use group(1507 cases,50.25%)was larger than the combined-use group(1 492 cases,49.75%).In terms of the number of drugs used in combination,one(39.01%)and two(38.14%)were the main types;in terms of medication types,combination therapy with Western medicine(62.27%)and simultaneous use of Western medicine and other Chinese materia medica(26.14%)were the main methods;the top three drugs with the highest frequency of combination use were glucosamine capsules,imrecoxib tablets and sodium hyaluronate injection.The top three drug combinations with the highest support were"Huoxue Zhishang Powder+imrecoxib tablets","glucosamine capsules+imrecoxib tablets"and"glucosamine capsules+sodium hyaluronate injection".Inter-group comparisons showed that the medication duration for Wangbi Tablets in CMS I was longer than in CMS Ⅱ and CMS Ⅲ(P<0.01).The proportion of patients on monotherapy in CMS I(62.11%)was higher than in CMS Ⅱ(46.54%)and CMS Ⅲ(56.86%)(P<0.001).Among patients in CMS I(16.41%)and CMS Ⅲ(21.24%),the highest proportion used one combined medication,whereas in CMS Ⅱ,the highest proportion was for those using two combined medications(20.50%).In all three groups,CMS I(19.53%),CMS Ⅱ(33.70%)and CMS Ⅲ(30.72%),the highest proportion of combined medications was Western medicine.Conclusion More than half of the patients treated KOA with Wangbi Tablets alone.Approximately one-fifth of the patients were in CMS I,with a median pain score of 8.The average duration of medication for patients in CMS I,CMS Ⅱ and CMS Ⅲ decreases,and there is no obvious pattern in the medication method at different stages;combination therapy is represented by"Huoxue Zhishang Powder+imrecoxib tablets"and"glucosamine capsules+imrecoxib tablets".

Objective To construct an evidence-based practice program of discharge preparation services for hip replacement patients based on the best evidence,and to evaluate its clinical effects,aiming to provide references for the implementation of relevant interventions.Methods Knowledge to Action Framework was used as a guide to summarise the best evidence on discharge preparation services for hip replacement patients and to select services based on clinical context.We selected 38 hip replacement patients and 17 healthcare professionals from the De-partment of Orthopaedic Surgery at a tertiary A hospital in Shanghai in September-October 2023 to conduct a baseline review,identify facilitating and hindering factors,and develop a practice protocol.We also selected 38 hip replacement patients and 17 healthcare professionals from November-December 2023 on this ward for evidence-based practice.Nurses'rates of completion of review indicators,levels of knowledge of discharge preparation ser-vices,and discharge planning competencies were compared before and after practice.Patients'readiness for dis-charge,hip function,and unplanned readmissions were also compared before and after the practice.Results After evidence-based practice,nurses'completion rates of review indicators,knowledge of discharge preparation services,and discharge planning competencies were higher than baseline levels(P＜0.05).Hip replacement patients showed a significant improvement in readiness for discharge and hip function(P＜0.001).Conclusion The implementation of an evidence-based practice program of discharge preparation services improves nurses'knowledge and skills,and also contributes to the discharge readiness and hip function of hip replacement patients.

With the rapid development of synthetic biology, genetic engineering, and molecular manipulation methods in recent years, microalgae, as representatives of microbial cell factories, have been widely used as hosts in the production of high-value bioproducts, such as oils, pigments, proteins, and biofuels, demonstrating promising prospects of application in biochemical energy, food and drugs, and environmental protection. Despite these advancements, the low production efficiency of microalgae limits their industrial application. In addition to strain improvement and culture condition optimization, the regulation by exogenous chemical additives serves as a promising optimization strategy. This method relies on straightforward phenotypic screening and circumvents the necessity for intricate understanding of molecular targets in the metabolic and catabolic pathways involved in the synthesis of bioproducts. It enables rapid yield increasing of high-value bioproducts from microalgae and obtaining the required phenotypes. Although studies have reported the use of alternatives means such as exogenous additives to improve the growth of microalgae and the yield of high-value bioproducts, the classification and summarization of the types, applications, targeted strains, and molecular mechanisms of these additives are not comprehensive. Here, we review the studies using chemical inducers or enhancers to improve cell growth and high-value bioproduct accumulation in microalgae in recent years. This paper focuses on the types of exogenous additives, the effects of exogenous additives and their combinations on microalgae growth and high-value bioproduct accumulation, and the molecular mechanisms of related effects. We aim to provide information for researchers to use methods of synthetic biology to develop suitable cell chassis and harness microalgae for industrial production.

Objective To investigate the value of secreted frizzled-related protein 1(SFRP1),GATA binding protein 3(GATA3)combined with human papillomavirus deoxyribonucleic acid(HPV-DNA)in predicting the risk of postoperative recurrence of high-grade cervical intraepithelial neoplasia(CIN)with positive thin-prep cytologic test(TCT).Methods A total of 200 patients with high-grade CIN and positive TCT results from July 2021 to July 2023 were selected as study subjects.All patients underwent cervical conization,and were divided into recurrence group and non-recurrence group according to the recurrence status one year after surgery.The clinical data,HPV-DNA viral load,and the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cer-vical tissues were compared between the two groups.The HPV-DNA viral load,SFRP1 mRNA,and GATA3 mRNA expression levels in patients with different CIN grades were compared,and their cor-relations with CIN grade and the risk of postoperative recurrence were analyzed.The predictive val-ues of SFRP1,GATA3,and HPV-DNA for the risk of postoperative recurrence were analyzed.Results Among 200 patients,2 were lost during the follow-up period.The recurrence group(n=30)had higher proportions of CIN grade Ⅲ,glandular involvement,positive surgical margins,high-risk human papillomavirus(HPV),higher HPV-DNA viral load,and a higher proportion of HPV positivity at 6 months after surgery compared with the non-recurrence group(n=168),and the differences were statistically significant(P＜0.05).The relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues of the recurrence group were lower than those of the non-recur-rence group,and the differences were statistically significant(P＜0.001).The HPV-DNA level in pa-tients with CIN grade Ⅲ was higher than that in those with CIN grade Ⅱ,and the relative expres-sion levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were lower than those in patients with CIN grade Ⅱ,and the differences were all statistically significant(P＜0.001).Spearman cor-relation analysis showed that HPV-DNA was positively correlated with CIN grade(P＜0.001),while the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were neg-atively correlated with CIN grade(P＜0.001).Logistic regression analysis showed that HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were independ-ent influencing factors for the risk of postoperative recurrence(P＜0.001).The receiver operating characteristic(ROC)curve results showed that the areas under the curve(AUCs)for predicting the risk of postoperative recurrence by HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were 0.787,0.781,and 0.764,respectively,with sensitivities of 80.00％,76.67％,and 76.67％,and specificities of 74.40％,73.81％,and 67.26％,respec-tively.The AUC for the combined prediction of the risk of postoperative recurrence by the three indica-tors was 0.924,with a sensitivity of 80.00％and a specificity of 93.45％,which was superior to the pre-dictive values of each indicator alone(Z=3.159,3.306,4.018,P＜0.001).Conclusion HPV-DNA,SFRP1,and GATA3 in cervical tissues have certain predictive values for the risk of postoperative re-currence in patients with high-grade CIN and positive TCT results,and combined detection can im-prove the predictive efficacy.

AIM: To investigate the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters in patients with hypertensive retinopathy(HRP).METHODS: A total of 50 patients(22 left eyes and 28 right eyes)with HRP admitted to our hospital from June 2021 to June 2023 were retrospectively included as the experimental group, and 50 healthy physical examination subjects(22 left eyes and 28 right eyes)during the same period were included as the healthy group. Pearson correlation was used to analyze the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters.RESULTS: The AUC values of fundus blood flow parameters and carotid artery ultrasound blood flow parameters and their combined diagnosis of HRP were 0.853, 0.844 and 0.935, respectively. Pearson correlation analysis showed that carotid systolic peak blood flow velocity was negatively correlated with foveal avascular zone(FAZ)area, FAZ circumference and non-circularity index, and positively correlated with macular vascular density(all P<0.05). The end-diastolic blood flow velocity was positively correlated with FAZ area and macular vascular density(all P<0.05). The internal carotid artery resistance index was positively correlated with FAZ area(P<0.05).CONCLUSION: The combination of fundus blood flow parameters and carotid artery ultrasound blood flow parameters in the diagnosis of HRP has good application value in the diagnosis of HRP.

Objective To investigate the cognition level and behavior compliance of blood pressure measurement in community residents and analyze the related influencing factors, and to provide evidence for community health management and blood pressure control. Methods A questionnaire survey was conducted to investigate 4470 community patients. Questionnaires included basic personal information，blood pressure measurement cognition, and blood pressure measurement behavior related issues. SPSS 19.0 was used to analyze the basic information, blood pressure measurement cognition, and pressure measurement behavior of the survey subjects. Logistic regression was performed to analyze relevant factors affecting blood pressure measurement cognition and behavior compliance. Results The overall cognitive compliance rate for blood pressure measurement among the visiting community patients was 31.52%. Age, education level, and chronic disease had a statistically significant impact on the cognitive knowledge (P<0.05). The overall behavior compliance rate of blood pressure measurement among the community patients was 23.69%. The cognition, age and education had a statistically significant impact on the overall behavior compliance rate of blood pressure measurement (P<0.05). Conclusion The cognitive level and standardized behavior of blood pressure measurement of community patients need to be improved. More attention should be paid to the elderly, low education level residents and community residents without chronic diseases, to promote community residents to form correct and standardized behavior of blood pressure measurement through health education.

Objective To investigate the predictive value of the diagnostic model constructed by CT radiomics combined with clin-ical and CT features for the P53 mutation status in lung adenocarcinoma.Methods The data of 177 patients with lung adenocarcinoma were retrospectively collected,including 75 cases of P53 mutant type and 102 cases of wild type.They were randomly divided into training cohort(n=123)and validation cohort(n=54)in a 7∶3 ratio.The region of interest(ROI)was delineated using MaZda software,and the features were screened using the least absolute shrinkage and selection operator(LASSO).The predictive model was devel-oped based on logistic regression analysis,and its diagnostic efficacy was evaluated.Results There were statistically significant differences in lesion diameter,maximum solid component diameter,lobulation sign,and lymph node metastasis between the two groups in the training cohort(P＜0.05).The area under the curve(AUC)in the training cohort of the radiomics score model,clinical imaging feature model,and combined model were 0.778,0.759,and 0.817,and the AUC in the validation cohort were 0.668,0.722,and 0.783,respectively.The clinical decision curve suggested that the combined model demonstrated superior clinical net benefits.Conclusion The combined model constructed by CT radiomics,lesion diameter,and lymph node metastasis has better predictive value for the P53 mutation status in lung adenocarcinoma.

Objective To retrospectively analyze the efficacy and safety of combined hetrombopag in the treatment of cancer therapy induced thrombocytopenia(CTIT)after chemotherapy for germ cell tumors.Methods The data of patients with CTIT ≥ grade Ⅲcombined with chemotherapy for intracranial germ cell tumors admitted from January 2021 to March 2024 were collected and analyzed,and 33 patients met the enrollment criteria.The patients in the study group were treated with oral hetrombopag combined with subcutaneous injections of recombinant human thrombopoietin(rhTPO)or interleukin-11(IL-11),and those in the control group were treated with subcutaneous injections of rhTPO or IL-11.The differences of the two groups of patients in platelet counts,platelet-raising response rate,mean onset of action time,and prolongation of the next cycle of treatment before and after the treatment were compared to each other,and the adverse reactions of the two groups were also counted.Results The platelet counts of patients in both groups were improved post-treatment,with no statistical significance between the two groups for platelet count elevation on days d1,d2,and d3 of the medication(P＞0.05).The platelet elevation counts of the study group were significantly elevated on day d(7±3)after the medication compared with the control group,with a statistically significant difference(P＜0.05),and the rate of platelet elevation response increased with time prolongation.The mean time to onset of drug administration was 3(3,5)in the study group and 4(3,7)in the control group,with no statistically significant difference(P＞0.05).The incidence of prolongation of the time to the next cycle of treatment was 54.5％in the study group and 81.8％in the control group,and the difference between the two groups was not statistically significant(P＞0.05).Two patients in the study group developed mild reversible liver function abnormalities.Conclusion The efficacy of hetrombopag combined with subcutaneous injection of t rhTPO or IL-11 in the treatment of thrombocytopenia after chemotherapy for intracranial germ cell tumors is reliable,and it can significantly elevate platelet counts with tolerable adverse effects.

Rare diseases pose significant diagnostic and therapeutic challenges,carrying a high disease burden,their management critically reflects a nation's public health resilience.Currently,China faces key challenges such as scarce treatments,fragmented services,and low drug accessibility in rare disease care,which urgently require systemic solutions.Digital-intelligent technology as a key breakthrough are expected to resolve the challenges in this field.Although its application in the field of rare diseases is gradually expanding,there is a lack of systematic compilation of studies to elucidate how to precisely enhance the precision,synergy and sustainability of diagnosis and treatment.The key challenges in rare disease care concentrate in four areas:inefficiency in prenatal screening,uneven distribution of medical resources,low efficiency in social organization collaboration,and ineffective information dissemination.The"4C"strategy,based on digital-intelligent technology,can address these issues:①coordination,boost prenatal screening awareness and capacity via digital-intelligent platforms to strengthen prevention;②cooperation,deepen collaboration within specialist networks,empowering institutions to enhance diagnostic capacity;③co-creation,empower support organizations to optimize resources,efficiency;④cognition,minimize information dissipation through efficient platforms,improving patient and family quality of life.This establishes an integrated digital-intelligent rare disease model encompassing"screening-diagnosis-treatment-care".
