Storage, Disposal, and Use of Opioids Among Cancer Patients in Central China: A Multi-Center Cross-Sectional Study.

OBJECTIVE: Unsafe opioid-related practices can lead to abuse, diversion, and accidental overdoses. In this study, we aimed to describe the patterns and beliefs regarding the storage, disposal, and use of opioids among Chinese patients with cancer in their home settings, which remain unclear. METHODS: A multicenter cross-sectional survey was conducted in Hubei Province from October 2022 to June 2023. We collected information on the storage, disposal, and use of opioids among cancer pain inpatients in the oncology department. Logistic regression was used to estimate the factors associated with unsafe disposal and use of opioids. RESULTS: The survey included 221 patients with a median age of 62 years. Only 3.2% stored their opioids under lock and key, and 49.8% were unaware of proper disposal methods. Nearly one-fifth (19.5%) reported having received information on the safe storage (14.0%) and/or disposal (10.0%) of opioids. A total of 44.3% reported unsafe use by sharing (1.8%), losing (4.1%), or taking opioids at a higher dose than prescribed (42.5%). Patients who did not receive information on the safe disposal of opioids (OR = 4.57, P = .0423), had a history of alcohol use (OR = 1.91, P = .0399), and used opioids other than morphine (OR = 2.31, P = .0461) had higher odds of unsafe disposal practices. Individuals with an associate degree/bachelor's degree or above were less likely to dispose of (OR = 0.36, P = .0261) and use (OR = 0.31, P = .0127) opioids unsafely. CONCLUSION: A significant proportion of Chinese patients with cancer exhibit unsafe practices in the storage, disposal, and use of opioids. The study highlights an urgent need for implementing routine education programs and drug "take-back" initiatives to improve opioid-related practices.

Inequity in the utilization of the home and community integrated healthcare and daily care services in older adults with limited mobility in China.

BACKGROUND: This study aimed to analyze the needs and utilization of the home and community integrated healthcare and daily care services ("home and community care services" for short) among older adults in China and to investigate the inequity in services utilization. METHODS: Cross-sectional data were obtained from the 2018 China Health and Retirement Longitudinal Study. Needs and utilization rates of the home and community care services in older adults of 60 years old and above were analyzed. Binary logistic regression analysis was performed to explore the factors associated with services utilization among older adults with limited mobility. Concentration index, horizontal inequity index, and Theil index were used to analyze inequity in services utilization. Decomposition analyses of inequity indices were conducted to explain the contribution of different factors to the observed inequity. RESULTS: About 32.6% of older adults aged 60 years old and above had limited mobility in China in 2018, but only 18.5% of them used the home and community care services. Among the single service utilization, the highest using rate (15.5%) was from regular physical examination. Limited mobility, age group, income level, region, self-assessed health, and depression were statistically significant factors associated with utilization of any one type of the services. Concentration indices of any one type service utilization and regular physical examination utilization were both above 0.1, and the contribution of income to inequity were both over 60%. Intraregional factor contributed to about 90% inequity of utilizing any one type service, regular physical examination and onsite visit. CONCLUSIONS: This current study showed that older adults with needs of home and community care services underused the services. Pro-rich inequities in services utilization were identified and income was the largest source of inequity. The difference of the home and community care service utilization was great among provinces but minor across regions. Policies to optimize resources allocation related to the home and community care services are needed to better satisfy the needs of older adults with limited mobility, especially in the low-income group and the central region.

Dynamic changes in water resources and comprehensive assessment of water resource utilization efficiency in the Aral Sea basin, Central Asia.

The Aral Sea Basin in Central Asia faces significant challenges in improving water utilization and treatment because of frequent transboundary river water disputes and shortages of water resources. However, the traditional water resource utilization efficiency (WRUE) assessment models generally have the defect of over-validating evaluation results. To solve this problem, this study used the Coefficient of Variation method to constrain the self-contained weights in the traditional Data Envelopment Analysis (DEA) to construct an improved CV-DEA model, and assessed the WRUE of the Aral Sea Basin countries during 2000-2018 and compared the WRUE with that of the countries in the Mekong River Basin and Northeast Asia, then explored the factors influencing water utilization. The conclusions were drawn: since 1960, the runoff from the upper Amu Darya and Syr Darya rivers increased significantly, while the runoff from the lower Amu Darya River into the Aral Sea declined. Meanwhile, the water area of the Aral Sea shrank from 2.56 × 104 km2 to 0.70 × 104 km2 in 2000-2018, with the Northern Aral Sea remaining stable while the southern part shrinking sharply. The WRUE of the Aral Sea Basin (0.599, on average) was higher than that of the Mekong River Basin (0.547) and lower than that of Northeast Asia (0.885). Kazakhstan and Uzbekistan had the highest WRUE of 0.819 and 0.685 respectively, and the WRUE in both two countries improved from 2000 to 2018. Tajikistan (0.495) and Turkmenistan (0.402) experienced decreases in WRUEs. The high input redundancy of agricultural water consumption was the main driving force affecting WRUE in the basin.

In situ electro-generated Ni(OH)2 synergistic with Cu cathode to promote direct ammonia oxidation to nitrogen.

To solve the problem of low removal rate and poor N2 selectivity in direct electrochemical ammonia oxidation (EAO), commercial Ni foam and Cu foam were used as anode and cathode of the EAO system, respectively. The coupling effect between the cathode and anode promoted nitrogen cycling during the reaction process, which improved N2 selectivity of the reaction system and promoted it to achieve a high ammonia removal rate. This study showed that the thin Ni(OH)2 with oxygen vacancy formed on the surface of Ni foam anode played an effective role in the dimerization of intermediate products in ammonia oxidation to form N2. This electrochemical system was used to treat real goose wastewater containing 422.5 mg/L NH4+-N and 94.5 mg/L total organic carbon (TOC). After treatment, this electrochemical system achieved good performance with an ammonia removal rate of 87%, N2 selectivity of 77%, and TOC removal rate of 72%. Therefore, this simple and efficient system with Ni foam anode and Cu foam cathode is a promising method for treating ammonia nitrogen wastewater.

Effects of temperature on cathepsin B, cathepsin D and acid phosphatase during embryo development of the hard tick Haemaphysalis longicornis.

The effects of temperature on the expression patterns and enzyme activity of cathepsin B (HlCatB), cathepsin D (HlCatD) and acid phosphatase (HlACP) during the embryo development of Haemaphysalis longicornis (bisexual population) were investigated in this study. Eggs were exposed to 20 °C (low temperature), 26 °C (normal temperature), and 30 °C (high temperature) immediately after laying, and collected on odd days of embryo development to measure HlCatB, HlCatD and HlACP gene expression using quantitative real-time PCR, as well as three enzyme activities using spectrophotometry. Then the associations between mRNA expression levels of three enzymes and their enzyme activities were assessed. Compared with normal temperature, the mRNA expression peaks of HlCatB were higher and appeared later at low and high temperatures and the activity of HlCatB increased on most days of embryonic development at high temperature. As for HlCatD, the expression peak appeared later at low temperature, but earlier at high temperature. The activity peaks of HlCatD were lower and appeared earlier at low and high temperatures. As for HlACP, the expression peak was higher and appeared later at low temperature, whereas it formed no prominent peak at high temperature. The activity peak of HlACP was higher at low temperature, but lower at high temperature. The linear regression analysis showed that activities of three enzymes were associated with their mRNA expression levels (P < 0.05). Three enzymes are involved in the embryo adaptation to temperature stress. Moreover, the mRNA expression level may be another factor affecting its enzyme activity.

Voriconazole-induced severe skin allergy and neurological adverse event in a liver failure patient: A case report.

Here we report a case of an acute-on-chronic liver failure (ACLF) patient with diffused skin allergy pervading from the chest, abdomen, back, knees to perineum, with red colour and partially desquamation as well as a neurological adverse (insomnia) event after voriconazole treatment. CASE SUMMARY: A 40-year-old man with liver failure in our hospital had received voriconazole for invasive fungal infection therapy, and while waiting for liver transplantation exhibited a severe diffuse rash and a neurological adverse event. WHAT IS NEW AND CONCLUSION: To the best of our knowledge, this is the first report of a liver failure patient who suffered a severe allergy accompanied with a neurological adverse event after voriconazole administration.

Integration of UPLC-QE-MS/MS and network pharmacology to investigate the active components and action mechanisms of tea cake extract for treating cough.

The active components and mechanisms of tea cake extract (TCE) were investigated for treating cough. The components of TCE were tentatively identified by ultrahigh-performance liquid chromatography coupled with Q-Exactive MS/MS (UPLC-QE-MS/MS), whose targets were obtained from the Swiss Target Prediction database and the Traditional Chinese Medicine Systems Pharmacology database and analysis platform. Cough-related targets were retrieved from the Gene Cards and Online Mendelian Inheritance in Man database. After the intersection targets had been obtained, enrichment analysis of Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were determined, and the protein-protein interaction network and active compound-intersection target-KEGG pathway network were constructed. Core active compounds and their targets were validated with molecular docking. A total of 78 compounds were identified from TCE, including 24 flavonoids, 17 phenolic acids, 10 alkaloids, seven organic acids, five triterpenes, five amino acids, five coumarins, three carbohydrates, one anthraquinone and one other. A total of 347 intersection targets were obtained. The top five GO terms with the most significant P-values were responses to oxygen-containing compounds and organic substances, chemical and cellular responses to chemical stimulus, and regulation of biological quality. The top five KEGG pathways with the most significant P-values were: the PI3K-Akt signaling pathway, lipids and atherosclerosis, human cytomegalovirus infection, fluid shear stress and atherosclerosis, and proteoglycans in cancer. The top five core active compounds were quercetin, genistein, luteolin, kaempferol and emodin. The top five core targets were protein kinase B (Akt1), prostaglandin-endoperoxide synthase 2 (PTGS2), mitogen-activated protein kinase 1/3 (MAPK1/3) and phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1). The top five core active compounds could stably bind to their targets with LibDockScores higher than 100. Tea cake extract plays the antitussive role via multiple components and targets. Core targets (AKT1, MAPK1, MAPK3 and PIK3R1) and core components (quercetin, genistein, luteolin and kaempferol) involved in the PI3K-Akt signaling pathway are worth more attention in subsequent validation experiments.

Validation of the patient-reported experience measure for care in Chinese hospitals (PREM-CCH).

BACKGROUND: A psychometrically validated instrument to measure patient experience in Chinese public hospitals would be useful and is currently lacking. Our research team developed the Patient-Reported Experience Measure for Care in Chinese Hospitals (PREM-CCH). We aimed to validate this PREM-CCH in the present study. METHODS: Data were drawn from a cross-sectional patient survey in 2016. Complete responses from 2293 outpatients and 1510 inpatients were included. Separate psychometric evaluation was carried out on outpatient and inpatient PREM-CCHs in terms of exploratory factor analysis, internal consistency, construct validity and criterion validity. RESULTS: The validated outpatient PREM-CCH contained 22 items and five Factors, i.e. Communication and information, Professional competence, Medical costs, Efficiency, and Hospital recommendation. The validated inpatient PREM-CCH contained 19 items and six Factors, i.e. Communication and information, Professional competence, Medical costs, Efficiency, Health outcomes, and Hospital recommendation. The PREM-CCH showed satisfactory internal consistency, construct validity and criterion validity. CONCLUSIONS: The PREM-CCH is one of the first validated instruments capturing patient experience of care in the context of Chinese public hospitals. It performed well in the psychometric evaluation. It consists of a basic set of items important to patients that could be applicable to public hospitals in China and actionable to inform quality improvement initiatives.

Exploring pathways to outpatients' satisfaction with health care in Chinese public hospitals in urban and rural areas using patient-reported experiences.

BACKGROUND: This study aimed to measure outpatients' general satisfaction with and experiences of different aspects of health care in Chinese public hospitals and to investigate to what extent general satisfaction could be explained by patients' experiences in public hospitals located at urban and rural areas. METHODS: Data on 4782 outpatients were derived from a patient survey in 9 city-level (urban) and 16 county-level (rural) public hospitals across China in 2016. According to Donabedian's model, questions on patients' experiences were categorized into six aspects under "structure" and "process", with general satisfaction representing "outcome". The Chi-square tests were used to test the differences in patients' experiences and general satisfaction between urban and rural areas. The Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to estimate effects of patients' experiences on general satisfaction. RESULTS: Compared with respondents in rural areas, there were significantly higher percentages of respondents in urban areas reporting satisfaction and positive experiences in most aspects. As manifested by the path coefficients in PLS models, the positive effect of professional competence (0.197) on general satisfaction was the most significant in respondents at urban areas, followed by communication and information (0.183), and caring attitudes and emotional support (0.174). Among respondents at rural areas, the positive effect of environment facilities (0.199) was the most significant, followed by caring attitudes and emotional support (0.188), and professional competence (0.179). The PLS models explained 44.9 and 46.0% of variations in patient satisfaction at urban and rural areas, respectively. CONCLUSIONS: Levels of patient satisfaction and experiences at Chinese public hospitals were higher in urban than in rural areas. Outpatients' experiences of professional competence, caring attitudes and emotional support were strongly related to their satisfaction in both settings. However, among respondents in urban areas, experiences of communication and information were more strongly related to satisfaction, whereas among respondents in rural areas, experiences of environment and facilities were more strongly related to satisfaction.

[Comprehensive mass spectrum analysis of two flavone-6,8-C-di-glycosides and its application by high resolution electrospray ionization tandem mass spectroscopy in both negative and positive ion modes].

The tandem mass spectrum of apigenin-6,8-C-di-glucoside( 1) and apigenin-6-C-glucose-8-C-rhamnoside( 2) were obtained by high resolution electrospray ionization mass spectrometry( HR-ESI-MS/MS) in both positive and negative ion modes. The elemental composition of each ion was determined according to its accurate mass-to-charge,hence,the fragmentation pathways of each compound were proposed in both negative and positive ion modes. Comprehensive analysis of each ion and its proposed fragmentation pathways of the two compounds was initially conducted in both negative and positive ion mode HR-ESI-MS/MS to explore the diagnostic ions for flavone-6,8-C-di-glycosides and the characteristic ions for each compound and their cleavage rules. The results showed that a family of fragmentation ions with m/z 353,325,311,297 in ESI(-)-MS and m/z 355,325,307,295 in ESI( +)-MS could be the diagnostic ions of flavone-6,8-C-di-glycoside,and characteristic neutral loss could be assigned to glycosyl substitution,for example,neutral losses of C_4H_8O_4( 120),C_3H_6O_3( 90),C_2H_4O_2( 60) for glucoside substitution while neutral losses of C_4H_8O_3(104),C_3H_6O_2( 74),C_2H_4O( 44) for rhamnoside substitution. Furthermore,only one H_2O loss from mother ion( [M-H]-) was observed for 1 & 2 in ESI(-)-MS while five to six H2 O loss from mother ion( [M+H]+) was observed for 1 & 2 in ESI( +)-MS to produce a family of ions by subsequent loss of H_2O,which could be applied for glucosyl difference. The flavone-6,8-C-di-glycosides in both ESI( +)-MS and ESI(-)-MS showed the cleavage similarity at sugar substitutions. However,there were much more differences by the fragmentation pathways and neutral losses between ESI( +)-MS and ESI(-)-MS as following,hyperconjugation ions by subsequent loss of H_2O from precursor ions of flavone-6,8-C-di-glycosides in ESI( +)-MS were not observed in ESI(-)-MS; the subsequent neutral loss of CH_2O in ESI( +)-MS were rarely observed in ESI(-)-MS; the loss of CO only happen at C-ring of flavone ESI( +)-MS other than glycosyl position in ESI(-)-MS; the C4-chain neutral loss of flavone-6,8-C-di-glycosides happened at 8-C-glycosyl position other than at 6-C-glycosyl position. The above cleavage rules and diagnostic ions of ESI( +)-MS were successfully applied for the structure identification of 4 flavone-6 C,8 C-diglycosides from the stem extract of Dendrobium officinale as vicenin Ⅱ,vicenin Ⅰ,isoschaftoside,schaftoside as well as one flavone-O-glysoside named rutin,which were supported by ESI(-)-MS data as well.

Gastric Mammalian Target of Rapamycin Signaling Contributes to Inhibition of Ghrelin Expression Induced by Roux-En-Y Gastric Bypass.

BACKGROUND/AIMS: Roux-en-Y Gastric Bypass, RYGB, is the most effective strategy to control body weight in morbid obesity. RYGB leads to rapid improvement of glycemic status and weight loss, which are largely attributed to the alteration of gastrointestinal hormones including ghrelin. The current study examined potential mechanisms of altered ghrelin synthesis after RYGB. METHODS: Gastric mammalian target of rapamycin (mTOR) signaling, ghrelin synthesis and secretion were determined in lean or obese male mice with or without RYGB operation, as well as in obese patients pre- and post-RYGB surgery. Ghrelin expression and mTOR signaling were investigated by western blotting and immunohistochemistry. Ghrelin mRNA levels were detected by real-time PCR. Plasma ghrelin was measured by enzyme immunoassay. RESULTS: mTOR activity in the gastric fundus was significantly lower than in the forestomachs. Both of them were decreased after 24h fasting. A significant negative correlation was found between gastric levels of phospho-S6 (phospho-S6 ribosomal protein) and proghrelin during changes of energy status. mTOR activity was activated, whereas ghrelin expression was inhibited by Roux-en-Y Gastric Bypass in both rodents and human beings. Increment of ghrelin synthesis and decline of mTOR signaling induced by rapamycin were significantly reversed by RYGB in both lean and obese mice. Administration of Ad-S6K1 (adenovirus-mediated p70 ribosomal protein subunit 6 kinase 1) from tail vein suppressed the expression of ghrelin in RYGB-operated mice relative to control animals. CONCLUSION: mTOR is therefore a gastric fuel sensor whose activity is linked to the regulation of ghrelin after Roux-en-Y Gastric Bypass.

What do patients care most about in China's public hospitals? Interviews with patients in Jiangsu Province.

BACKGROUND: Evaluations on different aspects of the performance of public hospitals in China have been conducted, usually based on indicators developed by literature review and expert suggestions. The patient perspective was not always considered. This study aims to identify what patients care most about in China's public hospitals exclusively from a patient perspective. METHODS: A mix of stratified sampling and typical sampling was used to select 15 public hospitals in Jiangsu Province of China. In each sampled hospital, a convenient sample of six outpatients and six inpatients was selected to conduct face-to-face individual interviews. An interview guide consisting of six open-ended questions was designed. Donabedian's quality of care framework was applied to categorize themes and subthemes, which were generated from patients' interviews by using the conventional content analysis approach. Frequencies of themes and subthemes were counted. RESULTS: Nine key themes were identified regarding patients' concerns about hospital care, which were environment and facilities, professional competence, hospital reputation, and morals of medical staff in the "structure" category of Donabedian's framework, caring attitudes and emotional support, medical costs, communication and information, and efficiency and coordination of care in the "process" category, and health outcomes in the "outcome" category. CONCLUSIONS: This study has identified and prioritized the aspects that patients care most about in China's public hospitals in Jiangsu Province exclusively from a patient perspective. A measurement tool of patient-reported experiences in public hospitals could be built based on this study. Efforts should be made to represent the patient perspective to further improve the reform of public hospitals in China.

Synthesis of MPEG-b-PLLA Diblock Copolymers and Their Crystallization Performance with PDLA and PLLA Composite Films.

Methoxy poly(ethylene glycol)-block-poly(L-lactide) (MPEG-b-PLLA) has a wide range of applications in pharmaceuticals and biology, and its structure and morphology have been thoroughly studied. In the experiment, we synthesized MPEG-b-PLLA with different block lengths using the principle of ring-opening polymerization by controlling the amount of lactic acid added. The thermodynamic properties of copolymers and the crystallization properties of blends were studied separately. The crystallization kinetics of PDLA/MPEG-b-PLA and PLLA/MPEG-b-PLA composite films were studied using differential scanning calorimetry (DSC). The results indicate that the crystallization kinetics of composite films are closely related to the amount of block addition. The crystallinity of the sample first increases and then decreases with an increase in MPEG-b-PLLA content. These results were also confirmed in polarized optical microscope (POM) and wide-angle X-ray diffraction (WAXD) tests. When 3% MPEG-b-PLLA was added to the PDLA matrix, the blend exhibited the strongest crystallization performance.

LncRNA SNHG1 alleviates myocardial ischaemia-reperfusion injury by regulating the miR-137-3p/KLF4/TRPV1 axis.

AIMS: Myocardial ischaemia-reperfusion injury (MIRI) contributes to serious myocardial injury and even death. Long non-coding RNAs (lncRNAs) have been reported to play pivotal roles in the occurrence and development of MIRI. Here, the detailed molecular mechanism of lncRNA SNHG1 in MIRI was explored. METHODS AND RESULTS: A cell model of MIRI was established through hypoxia/reoxygenation (H/R) stimulation. Cell viability and pyroptosis were evaluated utilizing MTT, PI staining, and flow cytometry. Interleukin (IL)-1ß and IL-18 secretion levels were examined by ELISA. The gene and protein expression were detected by RT-qPCR and western blot, respectively. Dual luciferase reporter gene, RIP and ChIP assays were performed to analyse the molecular interactions. The results showed that lncRNA SNHG1 overexpression alleviated H/R-induced HL-1 cell pyroptosis (all P < 0.05). LncRNA SNHG1 promoted KLF4 expression by sponging miR-137-3p. miR-137-3p silencing alleviated H/R-induced pyroptosis in HL-1 cells (all P < 0.05), which was abolished by KLF4 knockdown (all P < 0.05). KLF4 activated the AKT pathway by transcriptionally activating TRPV1 in HL-1 cells (all P < 0.05). TRPV1 knockdown reversed the alleviation of SNHG1 upregulation on H/R-induced pyroptosis in HL-1 cells (all P < 0.05). CONCLUSIONS: These results showed that lncRNA SNHG1 assuaged cardiomyocyte pyroptosis during MIRI progression by regulating the KLF4/TRPV1/AKT axis through sponging miR-137-3p. Our findings may provide novel therapeutic targets for MIRI.

Development and Application of a Physiologically Based Pharmacokinetic Model for Elagolix in the Adult and Adolescent Population.

INTRODUCTION: Endometriosis, a common and distressing gynecological condition, affects fertility and causes pain, is often managed with medications such as Elagolix. The present study aimed to construct a physiologically based pharmacokinetic (PBPK) model for elagolix to predict its pharmacokinetics in different populations, including those with special conditions, to enhance treatment strategies for endometriosis. METHODS: The PBPK model was optimized using observational data based on the oral administration of elagolix in a healthy Chinese population under fasting conditions. Model accuracy was further verified by comparing the predicted postprandial elagolix concentration data for healthy Chinese individuals with observed data and by comparing these values with the predicted values in a US population model with renal injury or following multiple-dose administration. RESULTS: Elagolix pharmacokinetic (PK) profiles in the Chinese and American populations exhibited no differences that were attributable to ethnicity. The model predicted in vivo PK in adolescents aged 14-18 years, revealing no clinically significant differences in the effects of elagolix between adolescents and adults. In addition, no predicted PK differences in individuals with overweight were observed. However, notable variations emerged in those classified as obesity class 2 and above compared to healthy individuals. CONCLUSION: Our study presents a novel PBPK model for elagolix in healthy Chinese women, addressing a clinical data gap for its use in adolescents and obese patients. By validating the model with real-world factors, including diet and renal impairment, we provide initial pharmacokinetic predictions for these populations, contributing to a more informed clinical approach.

Acupuncture Point Selection Patterns for Chemotherapy-Induced Nausea and Vomiting: A Data Mining Analysis.

INTRODUCTION: Chemotherapy-induced nausea and vomiting (CINV) significantly impacts the quality of life of cancer patients undergoing treatment, often leading to treatment interruptions and compromised adherence to therapy. Our objective was to identify patterns for selecting the optimal acupoints and explore the treatment principles behind forming effective acupoint combinations for CINV. METHODS: Clinical trials were retrieved from eight databases. Descriptive statistics analysis was performed, followed by association rule mining, network analysis, hierarchical cluster analysis, and correlation analysis, all implemented with R software. RESULTS: In summary, this study investigated the potential acupoints and combinations for CINV treatment in 104 published controlled clinical trials and randomized controlled trials. 104 prescriptions involving 48 acupoints were extracted. ST36, PC6, CV12, SP4, LI4, and ST25 appeared to be the most frequently used acupoints for CINV. Stomach Meridian, Conception Vessel (Renmai), and Pericardium Meridian were the most common selected meridians. The lower limbs, chest, and abdomen appeared as the predominant sites for acupoint selection. Co-occurrence network analysis indicated that ST36, PC6, and CV12 were central key node acupoints. The clustering analysis displayed the treatment principle of "harmonizing the stomach, stopping vomiting, and descending counterflow." Association rule mining revealed that the combination of CV4, CV12, ST36, CV6, and PC6 emerged as the optimal acupoint combination for effectively treating CINV. CONCLUSION: Overall, our research provides evidence-based optimal acupuncture prescription for acupuncturists to treat CINV and presents a complementary therapy for chemotherapy physicians as well as patients to address CINV symptoms.

Current scenario and challenges of clinical pharmacists to implement pharmaceutical care in DRG/DIP payment hospitals in China: a qualitative interview study.

Purpose: The Diagnosis-Related Group (DRG) or Diagnosis-Intervention Packet (DIP) payment system, now introduced in China, intends to streamline healthcare billing practices. However, its implications for clinical pharmacists, pivotal stakeholders in the healthcare system, remain inadequately explored. This study sought to assess the perceptions, challenges, and roles of clinical pharmacists in China following the introduction of the DRG or DIP payment system. Methods: Qualitative interviews were conducted among a sample of clinical pharmacists. Ten semi-structured interviews were conducted, either online or face to face. Thematic analysis was employed to identify key insights and concerns related to their professional landscape under the DRG or DIP system. Results: Clinical pharmacists exhibited variable awareness levels about the DRG or DIP system. Their roles have undergone shifts, creating a balance between traditional responsibilities and new obligations dictated by the DRG or DIP system. Professional development, particularly concerning health economics and DRG-based or DIP-based patient care, was highlighted as a key need. There were calls for policy support at both healthcare and national levels and a revised, holistic performance assessment system. The demand for more resources, be it in training platforms or personnel, was a recurrent theme. Conclusion: The DRG or DIP system's introduction in China poses both opportunities and challenges for clinical pharmacists. Addressing awareness gaps, offering robust policy support, ensuring adequate resource allocation, and recognizing the evolving role of pharmacists are crucial for harmoniously integrating the DRG or DIP system into the Chinese healthcare paradigm.

Application of nano-radiosensitizers in non-small cell lung cancer.

Radiotherapy stands as a cornerstone in the treatment of numerous malignant tumors, including non-small cell lung cancer. However, the critical challenge of amplifying the tumoricidal effectiveness of radiotherapy while minimizing collateral damage to healthy tissues remains an area of significant research interest. Radiosensitizers, by methods such as amplifying DNA damage and fostering the creation of free radicals, play a pivotal role in enhancing the destructive impact of radiotherapy on tumors. Over recent decades, nano-dimensional radiosensitizers have emerged as a notable advancement. Their mechanisms include cell cycle arrest in the G2/M phase, combating tumor hypoxia, and others, thereby enhancing the efficacy of radiotherapy. This review delves into the evolving landscape of nanomaterials used for radiosensitization in non-small cell lung cancer. It provides insights into the current research progress and critically examines the challenges and future prospects within this burgeoning field.

Availability and quality of emergency obstetric care, an alternative strategy to reduce maternal mortality: experience of Tongji Hospital, Wuhan, China.

The burden of maternal mortality (MM) and morbidity is especially high in Asia. However, China has made significant progress in reducing MM over the past two decades, and hence maternal death rate has declined considerably in last decade. To analyze availability and quality of emergency obstetric care (EmOC) received by women at Tongji Hospital, Wuhan, China, this study retrospectively analyzed various pregnancy-related complications at the hospital from 2000 to 2009. Two baseline periods of equal length were used for the comparison of variables. A total of 11 223 obstetric complications leading to MM were identified on a total of 15 730 hospitalizations, either 71.35% of all activities. No maternal death was recorded. Mean age of women was 29.31 years with a wide range of 14-52 years. About 96.26% of women had higher levels of schooling, university degrees and above and received the education of secondary school or college. About 3.74% received primary education at period two (P2) from 2005 to 2009, which was significantly higher than that of period one (P1) from 2000 to 2004 (P<0.05) (OR: 0.586; 95% CI: 0.442 to 0.776). About 65.69% were employed as skilled or professional workers at P2, which was significantly higher than that of P1 (P<0.05). About 34.31% were unskilled workers at P2, which was significantly higher than that of P1 (P<0.05). Caesarean section was performed for 9,930 women (88.48%) and the percentage of the procedure increased significantly from 19.25% at P1 to 69.23% at P2 (P<0.05). We were led to conclude that, despite the progress, significant gaps in the performance of maternal health services between rural and urban areas remain. However, MM reduction can be achieved in China. Priorities must include, but not limited to the following: secondary healthcare development, health policy and management, strengthening primary healthcare services.

Healthcare professionals' knowledge, attitude and practice towards National Centralized Drug Procurement policy in central China: A cross-sectional study.

Background: National Centralized Drug Procurement (NCDP), an ongoing government-led policy starting in 2019 in China, aimed at reducing drug costs. During the implementation of NCDP, healthcare professionals (HCPs) still have a certain degree of concern about the policy, which affects the clinical use of related drugs. Objective: This study aims to assess the level of knowledge, attitude and practice (KAP) of HCPs towards NCDP policy, together with the associated factors that determine their KAP. Methods: A cross-sectional study was conducted between September and November of 2021 in 30 hospitals in Hubei province in Central China. A self-designed online questionnaire including KAP towards NCDP policy was administered to HCPs. Logistic regression analysis was adopted to identify the factors associated with KAP. Results: A Total of, 742 HCPs completed the questionnaires. 43.4% of HCPs had good knowledge, 24.7% had a positive attitude, and 23.7% held good practice. Through multivariate logistic regression analysis, HCPs who are males, pharmacists, with senior professional titles and 6-10 years of professional working experience contributed to a higher knowledge level. Pharmacists and HCPs with good knowledge were more likely to have positive attitudes, while HCPs with higher education were less likely to have positive attitudes. Pharmacists, HCPs who had 11-20 years of professional working experience, worked in medium-size urban areas or had good knowledge were more likely to have good practice. Good practice is also associated with the positive attitude towards the efficacy of centralized-purchased medicines and impacts of NCDP policy. Conclusion: Only a small percentage of HCPs had good KAP towards NCDP policy. Pharmacists showed better KAP than physicians. The positive attitude towards the efficacy of centralized-purchased medicines and impacts of NCDP policy contributed to better practice. High-quality clinical evidence on the therapeutic effects and safety of the centralized-purchased drugs is needed.
