The relationship of MITF gene expression and promoter methylation with plumage colour in quail

1. This study focused on the relationship between MITF mRNA expression and plumage colour in quail and the effect of promoter methylation on the expression of MITF mRNA.2. The CDS region of MITF mRNA was cloned by RT-PCR, followed by DNA sequencing. The RT-qPCR method was used to analyse the expression levels of MITF mRNA in dorsal skin tissue in Korean quail and Beijing white quail. The promoter region of the MITF gene was cloned, and the CpG island was predicted by the CpGplot program. The methylation levels of the CpG island were analysed using BS-PCR technology.3. Quail MITF mRNA contains a 1,476 bp complete ORF, which encodes a 492 amino acid residue protein. The MITF protein has no signal peptide or transmembrane region. The expression of MITF mRNA in dorsal tissue of Korean quail was significantly higher than that in Beijing white quail (p < 0.01). Abundant cis-elements and a 346 bp CpG island were found in the promoter region of the MITF gene. The average methylation level of the CpG island was 22 (22%) in Korean quail, and 46 (30%) in Beijing white quail (p < 0.05).4. The hypermethylation of the MITF gene promoter region in Beijing white quail resulted in a decrease in expression level, which was related to white feather colour.

A sensitive bimetallic copper/bismuth metal-organic frameworks-based aptasensors for zearalenone detection in foodstuffs

Electrochemical aptasensors have emerged as promising platforms for effectivelydetection of various target analytes. Here, we developed a sensitive and selective electrochemical aptasensor for zearalenone (ZEN) determination based on a bimetallic organic framework (CuBi-BPDC). The results of HR-TEM, FE-SEM, XPS, etc. indicate the CuBi-BPDC possessing mixed nodes of Cu(II) and Bi(III) and multilayered nanosheets bearing nanoparticles. Due to its improved electrochemical activity and strong affinity for aptamers, the CuBi-BPDC-based aptasensor obtains a low limit of detection of 0.19 fg mL-1 (IUPAC S/N = 3) in a wide range of 1 fg mL-1-10 ng mL-1 via EIS and 0.73 fg mL-1 from 0 fg mL-1 to 1 × 107 fg mL-1 via DPV for ZEN detection, respectively. Moreover, the excellent selectivity allows this aptasensor to specifically identify ZEN from other interfering substances in raw milk and rice, indicating the potential applicability of the CuBi-BPDC-based aptasensor in sensitive and selective detection of ZEN.

[Medicinal Characteristics of Shao Jiu in Compendium of Materia Medica]

Modern Bai Jiu(liquor) was called Shao Jiu in ancient times.By consulting ancient books, it was found that there was a distillation and preparation process of Shao Jiu before the Ming Dynasty, but due to its high toxicity, the scope of application was limited, and there were few records of its medicinal use.However many records of its medicinal use was found in the Compendium of Materia Medica(«»).By comparing the medical books that recorded Shao Jiu in previous dynasties, it is found that the Compendium of Materia Medica comprehensively records the relevant cognition and application of the medicinal use of Shao Jiu for the first time. The book lists in detail the causes of the toxicity of Shao Jiu and the methods to avoid it, comprehensively expounds its characteristics, efficacy and indications, lists a variety of ways to use it, skillfully uses Shao Jiu to treat syphilis sores, and proposes that high-concentration Shao Jiu can be used as a solvent for medical liquor.The record of Shao Jiu in the Compendium of Materia Medica had a profound impact on the medical liquor of later generations.The use of Shao Jiu in the Qing Dynasty continued to expand, and the types of medicinal liquor were also constantly enriched. The record of Shao Jiu in the Compendium of Materia Medica can also provide a reference for the medicinal use of modern liquor.

Willingness to vaccinate against herpes zoster in Chinese urban population: a mixed-methods study

OBJECTIVE

Although the herpes zoster vaccine has been available in mainland China since June 2020, residents' knowledge of herpes zoster and the herpes zoster vaccine is poor, and vaccination rates are low, especially among the elderly, who are at high risk for herpes zoster. This study assessed willingness to be vaccinated against herpes zoster and factors associated with vaccination among urban residents in China.

METHODS

A mixed-methods study was conducted in community health centres from August 2022 to September 2022. We used convenience sampling to select 2864 residents from 9 Chinese cities for the quantitative study and 67 adults for the qualitative study. A structured questionnaire was used for the quantitative study, and data were collected through face-to-face interviews. Multinomial logistic regression was used to analyse factors associated with willingness to vaccinate. Qualitative data were analysed using thematic analysis of barriers to herpes zoster vaccination.

RESULTS

A total of 2864 eligible respondents were included in the study. Of these, 42.67% intended to receive the herpes zoster vaccine, 21.44% refused and 35.89% were hesitant. The results of the quantitative and qualitative analyses showed that the factors associated with respondents' willingness to be vaccinated against herpes zoster included: personal characteristics such as gender, age and income; knowledge and attitudes about herpes zoster and the vaccine; vaccine characteristics such as efficacy, safety and price; and other factors such as pain tolerance and accessibility to vaccination.

CONCLUSION

The low willingness to vaccinate, especially among the elderly, is mainly related to their poor knowledge and negative attitude towards the infection and vaccination. Therefore, health education about herpes zoster, immunisation promotion, and improvement of accessibility and affordability would be valuable in China.

The application of policy composite indicators to predicting the health risk and recovery: a global comparative investigation

OBJECTIVES

There emerges increasing doubt regarding whether the policy composite indicators are applicable to the COVID-19 pandemic. A few early studies demonstrate that the association between some composite indicators of policy preparedness and the risk of COVID-19 is statistically insignificant, and the relation between any composite indicators and recovery process (e.g., vaccination coverage) remains unexplored. To examine the relation between composite indicators and pandemic risk (as well as the vaccination coverage) with robustness, this study applies different policy preparedness indicators by using data from multi-sources.

STUDY DESIGN

A cross-sectional analysis was performed.

METHOD

Regression analysis is adopted to examine the relation between four policy preparedness indicators (i.e., [1] International Health Regulations core capacity index, [2] Global Health Security Index, [3] epidemic preparedness index, and [4] World Governance Index) and COVID-19-confirmed cases/death/vaccination coverage at different time points. The linear regression is performed, and the spatial distribution of indicators are illustrated.

RESULTS

Countries with higher ranking in policy preparedness indexes can experience less severity of pandemic risk (e.g., confirmed cases and mortality) and faster recovery process (e.g., higher vaccination coverage). However, slight disparity in effectiveness exists across different indicators.

CONCLUSION

Results show that the policy preparedness indicators have predictive value of the confirmed cases, mortality, and vaccination coverage of COVID-19 pandemic, given sufficiently long-time span is observed.

Study on the determinants of health professionals' performance on diabetes management care in China

BACKGROUND

As the direct providers of diabetes management care in primary health care facilities (PHFs) in China, health professionals' performance on management care of diabetes determines the quality of services and patients' outcomes. This study aims to analyze the key determinants of health professionals' performance on diabetes management care in PHFs in China.

METHODS

We conducted a cross-sectional study in 72 PHFs in 6 cities that piloted the contracted family doctor service (CFDS). Self-developed questionnaire was used to measure three kinds of factors (capacity, motivation and opportunity) potentially influencing the performance of health professionals. The performance of diabetes management care in the study was measured as whether health professionals delivered 7 service items required by the National Basic Public Health Service Guideline with a total of 7 points and was divided into three grades of good, medium and bad. The questionnaire is self-administered by all the health professionals involved in the study with the number of 434. The Chi-square tests were used to compare differences of performance on diabetes management care among health professionals with different characteristics. The ordinal logistic regression was used to analyze the determinants on the performance of diabetes management care.

RESULTS

Health professionals who got higher score on diabetes knowledge test had odds of better performance on diabetes management care (OR = 1.529, P < 0.001). health professionals with higher degree of self-reported satisfaction on training (OR = 1.224, P < 0.05) and perception of decreasing workload (OR = 3.336, P < 0.01) had odds of better performance on diabetes management care. While health professionals with negative feeling on information system support had odds of worse performance on diabetes management care (OR = 0.664, P < 0.01).

CONCLUSIONS

Attention should be paid to the training of health professionals' knowledge on diabetes management capacity. Furthermore, measures to improve training for health professionals could satisfying their needs for self-growth and improve the motivation of health professionals. The information system supporting management care should be improved continuously to improve the health professionals' working opportunities and decrease the workload.

Continuity of health care: measurement and application in two rural counties of Guangxi Province, China

BACKGROUND

Continuity of care (COC) is highly regarded in health promotion and health system strengthening. However, there is a lack of multidimensional quantitative assessment of continuity, making it challenging to evaluate and compare. Our objective was to create a novel measurement for COC and apply it in two rural counties in China to assess its validity and feasibility in evaluating health system reform.

METHOD

This study conducted a scoping literature review on COC, examining existing frameworks and indicators. Following an online expert poll, a composite indicator was developed using the analytical hierarchy process (AHP). The measurement tool was then applied to assess the current state of COC in two rural counties in China. In addition to descriptive analysis, demographic and economic characteristics were analyzed for their association with COC scores using t-tests and multiple linear regression models.

RESULTS

The final COC measurement encompasses three dimensions, six sub-dimensions, and ten individual indicators, which integrated and improved the current frameworks and indicators. Relational continuity, informational continuity, and management continuity were identified as the primary dimensions of COC measurement. The COC score is 0.49 in County A and 0.41 in County B, with information continuity being the highest-scoring dimension. Notably, the disparity in continuity scores is most pronounced among individuals with varying attitudes towards health, demonstrating a positive correlation.

CONCLUSION

The construction of the composite indicator in this study offers a scientific and effective metric for comprehensively measuring continuity of care. The empirical data analysis conducted in Western China serves as an illustrative application of the indicator, demonstrating its efficiency. The results obtained from this analysis provide a solid foundation and valuable reference for strengthening the health system.

Contrast-enhanced magnetic resonance angiography in the identification of prostatic arterial anatomy in patients with benign prostatic hyperplasia: prospective comparison with digital subtraction angiography

AIM

To evaluate the utility of contrast-enhanced magnetic resonance angiography (CE-MRA) for identifying prostatic artery (PA) anatomy in patients with benign prostatic hyperplasia (BPH) before PA embolisation (PAE), using digital subtraction angiography (DSA) as the reference standard.

MATERIALS AND METHODS

A total of 176 patients underwent pelvic CE-MRA at 3 T. DSA was performed within the following 7 days. Two interventional radiologists compared the CE-MRA findings with DSA findings to assess the anatomy of the PAs. The rates of correct identification of the origins and collaterals of the PAs by CE-MRA were calculated. The utility for predicting the optimal X-ray tube angle obliquity for visualising the origins of the PAs by CE-MRA was evaluated. An exact McNemar's test was used to compare the detection rates of the PAs and the collaterals with DSA versus CE-MRA. A two-sided p-value of <0.05 was considered statistically significant.

RESULTS

Of the 376 PAs identified by DSA, CE-MRA correctly identified the origins of 369 vessels (98.1%), with a 1.9% false-negative rate and no false-positive results. Of the 57 total collaterals identified by DSA, CE-MRA identified 50 vessels correctly (87.7%), with a 12.3% false-negative rate and no false-positive results. No significant differences were observed between CE-MRA and DSA in the identification of the PA origins (p=0.824) and the collaterals (p=0.327). The optimal degree for an oblique projection to visualise the origins of the PAs could be predicted accurately (100%) by pre-procedural CE-MRA.

CONCLUSION

CE-MRA before PAE can reliably predict the PA anatomy and facilitate procedural planning.

Investigation of the relationships among respiratory syncytial virus infection, T cell immune response and intestinal flora

The aim of this work was to evaluate the relationships among respiratory syncytial virus infection, T cell immune response and intestinal flora. Peer-reviewed papers published in English were collected through extensive searches performed in PubMed, Web of Science, Google Scholar, and China National Knowledge Infrastructure databases. The articles were reviewed to extract relevant information on the immune responses of Th1/Th2 and Treg/Th17 to respiratory syncytial virus infection in the body. RSV (Respiratory syncytial virus, RSV) infection leads to imbalance between Th1/Th2 and Treg/Th17 immune cells, resulting in Th2 or Th17 dominant immune responses, which can generate immune disorder and aggravate clinical symptoms. Intestinal micro-organisms play very important roles in maintaining stable immune environment, stimulating immune system maturation and balancing Th1/Th2 and Treg/Th17 immune systems in children. In our review of various papers from around the world, we speculated that the steady state of intestinal bacteria was disturbed after children got infected with RSV, resulting in intestinal flora disorder. Then, the imbalance between Th1/Th2 and Treg/Th17 immune cells was increased. Both intestinal flora disorder and RSV infection could cause cellular immunity imbalance of Th1/Th2 or Treg/Th17, eventually leading to disease deterioration and even a vicious cycle. Normal intestinal flora can maintain immune system stability, regulate the dynamic balance of Th1/Th2 and Treg/Th17 and prevent or mitigate adverse consequences of RSV infection. Because probiotics can improve intestinal barrier function and regulate immune response, they can effectively be used to treat children with recurrent respiratory tract infections. Using conventional antiviral therapy strategy supplemented with probiotics in the treatment of clinical RSV infection may be better for the body.

Correlation between input on public health services and work motivation among primary health workers in China

BACKGROUND

The integration of public health services into primary health care has been advocated and practiced worldwide for better management of preventable diseases. Health policy makers in China have started the reforms to better integrate public health services and clinical services, but public health services in China still remained neglected in primary health system. This study aimed to explore the input of Chinese primary health workers on delivering public health services and its association with their intrinsic working motivation in China.

METHODS

Data were collected from a cross-sectional survey conducted in 2019. Participants in this survey included 803 primary health workers in 75 primary health institutions in China. Questions about the input on clinical and public health services delivery and intrinsic working motivation were asked. A multiple linear regression model was adopted to investigate the correlation between intrinsic working motivation and the time input on public health service. The robustness of this model was checked with a generalized linear model.

RESULTS

Intrinsic motivation was found to have negative association with health workers' input on public health (β: -1.01, p < 0.05), with the robustness checked with a generalized linear model. The significance of this association differed in the group of urban community health centers and rural township health center. Other factors that had significant relationship with the input on public health services include the being nurses instead of doctors (p < 0.01), being a member of family doctor team (p < 0.01), recognition on relative importance of clinical services (p < 0.01), and perception on better exterior support (p < 0.01).

CONCLUSION

With higher intrinsic working motivation, primary health workers tended to spend less time on public health services. It reflected that doctors and nurses in primary healthcare institutions still perceived clinical treatment services as their main work responsibility and source of career recognition. Organizational level supports and system level policies should guide the primary health workers to increase their awareness on the importance of public health services and to cultivate their internal interests on public health services, in order to ensure sustainable input and performance improvement on public health services in primary health system in China.

A guideline for economic evaluations of vaccines and immunization programs in China

This study aimed to develop a consensus framework for economic evaluations of vaccines as a national guideline in China. Some unique and important aspects were particularly emphasized. Nineteen Chinese experts in the field of health economics and immunization decision-making were nominated to select and discuss relevant aspects of vaccine economic evaluations in China. A workshop attended by external experts was held to summarize unique and important aspects and formulate consensus recommendations. There were ten unique and/or important aspects identified for economic evaluations of vaccines in China, including study perspectives, comparator strategies, analysis types, model choices, costing approaches, utility measures, discounting, uncertainty, equity, and evaluation purposes. Background information and expert recommendations were provided for each aspect. Economic evaluations of vaccines should play an important role in China's immunization policy-making. This guideline can help improve the quality of economic evaluations as a good practice consensus.

[The textbooks in the North China Medical College]

The North China Medical College typically represented medical colleges for traditional Chinese medicine in the 1930s when many of them were set up. It was based on the principles of centring on traditional Chinese medicine, following western medicine and integrated medicine in teaching. This led to the emergence of a great number of people with a high level of traditional Chinese medicine and strong belief in it. In terms of the textbooks and handouts for western medicine, compared to similar textbooks in other medical colleges, such as the Medical College of Xie He, at that time, the textbooks in the North China Medical College covered a variety of perspectives and categories. It was found that 20 textbooks for western medicine in the North China Medical College were designed reasonably in content and were simple and applicable in teaching. More importantly, it contained some traditional Chinese medicine in different degrees, with its typical characteristics. The course design and textbook compilation provided references for the teaching in contemporary medical universities.

Work Motivation of Primary Health Workers in China: The Translation of a Measurement Scale and Its Correlation with Turnover Intention

Background

High turnover intention, as a manifestation of low work motivation, is a crucial barrier to strengthening primary health systems worldwide, including in China. Targeting those being less motivated will be a realistic choice to retain primary health workers. This study translate, adapt, and validate the Work Motivation Scale for Health Workers (WMSHW) scale to directly measure and rate health workers' motivation composition based on Self-Determination Theory, and assessed how health workers with different levels of motivation being associated with the turnover intention.

Methods

The process of translation and cross-cultural adaptation followed the recommendations of international guidelines. Participants include 1341 health workers within 75 primary health institutions from 6 provinces in China. The reliability and validity of the scale was analyzed. Cluster analysis in a person-centered approach and logistic regression analysis was used to understand how different combinations of motivations related to intention to leave.

Results

Confirmatory factor analysis indicated that the modified five-factor model had a better fit than the other models in accordance with the original English version. The factor loads were high and ranged from 0.70 to 0.9. Cronbach's alpha coefficients for five dimensions of the Chinese WMSHW ranged from 0.81 to 0.94, indicating the scale's high internal consistency. Four distinct clusters of work motivation were found in this study, representing low motivated, highly controlled, highly autonomous and highly motivated primary health workers. Compared with low motivation group, both controlled and autonomous motivation groups were more likely to have lower turnover intention. The negative relationship between motivation and intention to leave became stronger with the level of motivation increasing: highly controlled cluster (OR: 0.47; 95% CI: 0.35-0.63), highly autonomous (OR: 0.27; 95% CI: 0.18-0.41) and highly motivated (OR: 0.20; 95% CI: 0.15-0.27).

Conclusion

The Chinese version of WMSHW showed satisfactory reliability and validity and can be used as an instrument for measuring and rating the work motivation of Chinese health workers. The primary health workers were grouped into four motivation levels based on this scale. Both controlled and autonomous motivation could work in reduce the turnover intention, and the influence of autonomous motivation on retaining was stronger.

Incentives Promoting Contracted Family Doctor Service Policy to Improve Continuity and Coordination in Diabetes Patient Management Care in China

Background

As the first step toward building a gatekeeping system in China, the governments have introduced a contracted family doctor service (CFDS) policy in primary healthcare (PHC) facilities. This study was to examine the association between apply of incentive to improve the implementation of CFDS and the performance on diabetes management care.

Methods

We conducted a cross-sectional study in 72 PHC facilities in 6 cities that piloted the CFDS. Multivariate regression models were applied, based on a sample of 827 PHC providers and 420 diabetic patients.

Results

PHC providers who reported the performance being linked with increased income were 168.1 and 78.0% more likely to have good continuity and coordination of diabetes patient management care, respectively. Additional one-point percentage of PHC providers whose performance on CFDS was assessed was associated with 7.192 times higher probability of patients with control of blood glucose.

Discussion

Inclusion of incentives rewarding better performance on CFDS were associated with better delivery process and outcome performance on diabetes management care.

Conclusion

Design and implementation of the incentive should be accompanied with the policy of CFDS, in order to increase the proportion of performance-related income of PHC providers, thereby improving the quality of diabetes management care.

An extension of the RIGHT statement for introductions and interpretations of clinical practice guidelines: RIGHT for INT

OBJECTIVE

The purpose of the extension of the RIGHT Statement for INTroductions and INTerpretations of Clinical Practice Guidelines (RIGHT for INT) is to promote the development of comprehensive and clear articles that introduce and interpret clinical practice guidelines.

METHODS

The RIGHT for INT checklist was developed following methods recommended by the EQUATOR Network. The development process included three stages. In the first stage, a multidisciplinary team of experts was recruited by email and WeChat and further divided into three groups (a steering group, a consensus group, and a secretariat group); in the second stage, the initial items were collected by literature review and brainstorming; and in the third stage, the final items were formed through a Delphi survey and expert consultation.

RESULTS

A total of 40 initial items were collected through literature review and brainstorming. A final checklist of 27 items was formed after the Delphi survey and expert consultation. The RIGHT for INT checklist contains items on the following 10 topics: title, abstract, background of guideline interpretation, background of guideline development, guideline development methodology, recommendations, strengths, and limitations, implications for local guidelines and clinical research, dissemination and implementation, and reporting quality.

CONCLUSION

The RIGHT for INT checklist provides guidance for guideline interpreters on how to introduce and interpret clinical practice guidelines in a scientific and comprehensive manner.

Willingness to accept COVID-19 vaccine among the elderly and the chronic disease population in China

A cross-sectional field survey was conducted from November 2020 to January 2021 among 7259 participants to investigate the public perception, willingness, and information sources for COVID-19 vaccination, with the focus on the elderly and non-communicable chronic disease (NCD) population. Multiple logistic regressions were performed to identify associated factors of the vaccination willingness. The willingness rate of the elderly to accept the future COVID-19 vaccine (79.08%) was lower than that of the adults aged 18-59 (84.75%). The multiple analysis didn't identify significant relationship between NCD status and the vaccination intention. The main reasons for vaccine hesitancy by the public were: concern for vaccine safety, low infection risk, waiting and seeing others getting vaccinated, concern of vaccine effectiveness and price. Their relative importance differed between adults aged 18-59 and the elderly, and between adults aged 18-59 with or without NCD. Perception for vaccination importance, vaccine confidence, and trust in health workers were significant predictors of the vaccination intention in both age groups. The elderly who perceived high infection risk or had trust in governments were more likely to accept the vaccine. Compared with the adults aged 18-59, the elderly used fewer sources for COVID-19 vaccination information and more trusted in traditional media and family, relatives, and friends for getting vaccination recommendations. To promote vaccine uptake, the vaccination campaigns require comprehensive interventions to improve vaccination attitude, vaccine accessibility and affordability, and tailor strategies to address specific concerns among different population groups and conducted via their trusted sources, especially for the elderly.

Satisfaction of Township Hospitals Health Workers on How They Are Paid in China

BACKGROUND

Township Hospitals (THs) are crucial providers in China's primary health delivery system. Low job satisfaction of THs health workers has been one of biggest challenges to strengthening the health system in China. Even huge amounts of studies confirmed low remuneration level as a key demotivating factor though few studies have explored the feelings of health workers on how they were paid.

OBJECTIVE

To analyze how the key design of Performance-based Salary System (PBS) influences the satisfaction of health workers on the payment system in China's THs.

METHOD

A cross-sectional study was conducted in 47 THs in Shandong China, and a total of 1136 participants were recruited. Expectancy theory was applied to design the measurements on designs of PBS. The associations between PBS design and satisfaction of health workers were analyzed by logistic regression.

RESULTS

Three key components of PBS design were all related to the satisfaction of health workers. Those health workers who were aware of assessment methods were more likely to be satisfied with how they were paid (OR = 2.44, p < 0.001) compared with those being not aware of the methods. The knowledge on personal performance was also associated with being satisfied (OR = 3.34, p < 0.001). The percentage of floating income in total income was negatively associated with the satisfaction, and one percentage point increase in floating income proportion could result in the possibility of being satisfied decreasing by 2.82% (95%CI -4.9 to -0.7, p = 0.01). Subgroup analysis found that only in those with lower value on monetary income, the negative influence of more floating income was significant.

CONCLUSIONS

When policymakers or managers apply performance-related payment to incentivize certain work behavior, they should pay attention to the design details, including keeping transparency in the performance assessment criteria, clear performance feedback, and setting the proportion of the performance-related part based on the preference of health workers in certain cultural settings.

The safety and efficacy of transarterial chemoembolisation with bleomycin for hepatocellular carcinoma unresponsive to doxorubicin: a prospective single-centre study

AIM

To investigate the safety and efficacy of transarterial chemoembolisation (TACE) with bleomycin for hepatocellular carcinoma (HCC) unresponsive to doxorubicin.

MATERIALS AND METHODS

A randomised controlled trial was undertaken of HCC patients resistant to TACE with doxorubicin to assess the survival benefits of the experimental group (TACE with bleomycin) compared with the control group (TACE with doxorubicin). One hundred and seventy patients were allocated randomly between December 2015 and December 2017, and 80 patients of each group were analysed. The modified response evaluation criteria in solid tumours (mRECIST) was used to evaluated the tumour response every 4-6 weeks. The primary endpoint was median progression-free survival (mPFS) and median overall survival (mOS). Safety was assessed by post-procedure complications.

RESULTS

The study was completed in October 2018. Objective response rate (ORR) of the experimental group was 27.5% (22/80), mPFS and mOS was 5.8 and 8.1 months. ORR of the control group was 7.5% (6/80), mPFS and mOS was 2.9 and 4 months. The ORR were significantly different between two groups (χ² = 0.348, p<0.05). The differences of mPFS and mOS between the two groups were statistically significant (χ² = 2.865, p<0.05 and χ² = 0.926, p<0.05, respectively). There were no significant difference in post-procedure complications (p>0.05) and no major complications occurred.

CONCLUSION

It is suggested that TACE with bleomycin is a safe and effective method for HCC and bleomycin can be a second-line chemotherapeutic agent for the HCC patients unresponsive to TACE with doxorubicin.

Prevalence and factors associated with hepatitis B virus infection among household members: a cross-sectional study in Beijing

HBV prevention and control presents a global public health priority because of the tremendous economic and healthcare burdens involved. This study was designed to investigate the status of HBV epidemics among household members, and to analyze the risk factors of HBV infection in couples and their offspring. A total of 1,035 couples and 541 offspring were included. We sourced the data from a population-based serological survey conducted by the Beijing Center for Disease Prevention and Control in 2014. Chi-square test and multiple logistic were used to assess differences in the prevalence of categorical variables, and identify risk factors for HBV infection and exposure in couples and offspring after controlling for confounding factors. In couples, the prevalence of chronic HBV infection was 4.3% and the prevalence of exposure 32.7%. The prevalence of chronic HBV infection in offspring was 0.9%, and the prevalence of exposure 8.7%. Sharing syringes with others and living with a spouse who was infected or exposed to HBV were associated with a significantly higher risk for transmission of HBV for couples. In offspring, maternal HBV infection was a significant risk factor for HBV exposure. This study provides evidence that having household members infected or exposed to HBV increases the risk of HBV transmission, and in order to achieve better control of HBV infection effective strategies must be established to prevent intra-familial transmission.

Payment methods for healthcare providers working in outpatient healthcare settings

BACKGROUND

Changes to the method of payment for healthcare providers, including pay-for-performance schemes, are increasingly being used by governments, health insurers, and employers to help align financial incentives with health system goals. In this review we focused on changes to the method and level of payment for all types of healthcare providers in outpatient healthcare settings. Outpatient healthcare settings, broadly defined as 'out of hospital' care including primary care, are important for health systems in reducing the use of more expensive hospital services.

OBJECTIVES

To assess the impact of different payment methods for healthcare providers working in outpatient healthcare settings on the quantity and quality of health service provision, patient outcomes, healthcare provider outcomes, cost of service provision, and adverse effects.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase (searched 5 March 2019), and several other databases. In addition, we searched clinical trials platforms, grey literature, screened reference lists of included studies, did a cited reference search for included studies, and contacted study authors to identify additional studies. We screened records from an updated search in August 2020, with any potentially relevant studies categorised as awaiting classification.

SELECTION CRITERIA

Randomised trials, non-randomised trials, controlled before-after studies, interrupted time series, and repeated measures studies that compared different payment methods for healthcare providers working in outpatient care settings.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We conducted a structured synthesis. We first categorised the payment methods comparisons and outcomes, and then described the effects of different types of payment methods on different outcome categories. Where feasible, we used meta-analysis to synthesise the effects of payment interventions under the same category. Where it was not possible to perform meta-analysis, we have reported means/medians and full ranges of the available point estimates. We have reported the risk ratio (RR) for dichotomous outcomes and the relative difference (as per cent change or mean difference (MD)) for continuous outcomes.

MAIN RESULTS

We included 27 studies in the review: 12 randomised trials, 13 controlled before-and-after studies, one interrupted time series, and one repeated measure study. Most healthcare providers were primary care physicians. Most of the payment methods were implemented by health insurance schemes in high-income countries, with only one study from a low- or middle-income country. The included studies were categorised into four groups based on comparisons of different payment methods. (1) Pay for performance (P4P) plus existing payment methods compared with existing payment methods for healthcare providers working in outpatient healthcare settings P4P incentives probably improve child immunisation status (RR 1.27, 95% confidence interval (CI) 1.19 to 1.36; 3760 patients; moderate-certainty evidence) and may slightly increase the number of patients who are asked more detailed questions on their disease by their pharmacist (MD 1.24, 95% CI 0.93 to 1.54; 454 patients; low-certainty evidence). P4P may slightly improve primary care physicians' prescribing of guideline-recommended antihypertensive medicines compared with an existing payment method (RR 1.07, 95% CI 1.02 to 1.12; 362 patients; low-certainty evidence). We are uncertain about the effects of extra P4P incentives on mean blood pressure reduction for patients and costs for providing services compared with an existing payment method (very low-certainty evidence). Outcomes related to workload or other health professional outcomes were not reported in the included studies. One randomised trial found that compared to the control group, the performance of incentivised professionals was not sustained after the P4P intervention had ended. (2) Fee for service (FFS) compared with existing payment methods for healthcare providers working in outpatient healthcare settings We are uncertain about the effect of FFS on the quantity of health services delivered (outpatient visits and hospitalisations), patient health outcomes, and total drugs cost compared to an existing payment method due to very low-certainty evidence. The quality of service provision and health professional outcomes were not reported in the included studies. One randomised trial reported that physicians paid via FFS may see more well patients than salaried physicians (low-certainty evidence), possibly implying that more unnecessary services were delivered through FFS. (3) FFS mixed with existing payment methods compared with existing payment methods for healthcare providers working in outpatient healthcare settings FFS mixed payment method may increase the quantity of health services provided compared with an existing payment method (RR 1.37, 95% CI 1.07 to 1.76; low-certainty evidence). We are uncertain about the effect of FFS mixed payment on quality of services provided, patient health outcomes, and health professional outcomes compared with an existing payment method due to very low-certainty evidence. Cost outcomes and adverse effects were not reported in the included studies. (4) Enhanced FFS compared with FFS for healthcare providers working in outpatient healthcare settings Enhanced FFS (higher FFS payment) probably increases child immunisation rates (RR 1.25, 95% CI 1.06 to 1.48; moderate-certainty evidence). We are uncertain whether higher FFS payment results in more primary care visits and about the effect of enhanced FFS on the net expenditure per year on covered children with regular FFS (very low-certainty evidence). Quality of service provision, patient outcomes, health professional outcomes, and adverse effects were not reported in the included studies.

AUTHORS' CONCLUSIONS

For healthcare providers working in outpatient healthcare settings, P4P or an increase in FFS payment level probably increases the quantity of health service provision (moderate-certainty evidence), and P4P may slightly improve the quality of service provision for targeted conditions (low-certainty evidence). The effects of changes in payment methods on health outcomes is uncertain due to very low-certainty evidence. Information to explore the influence of specific payment method design features, such as the size of incentives and type of performance measures, was insufficient. Furthermore, due to limited and very low-certainty evidence, it is uncertain if changing payment models without including additional funding for professionals would have similar effects. There is a need for further well-conducted research on payment methods for healthcare providers working in outpatient healthcare settings in low- and middle-income countries; more studies comparing the impacts of different designs of the same payment method; and studies that consider the unintended consequences of payment interventions.

[Application effect of sustainable skin-stretching device in scalp and soft tissue defect]

Objective: To explore the application effect of sustainable skin-stretching device in scalp and soft tissue defect. Methods: From June 2017 to January 2020, 5 patients (3 males and 2 females, aged 31-57 (38.0±2.1) years) with large area of scalp and soft tissue defect and skull exposure were admitted to Department of Reparative and Reconstructive Surgery of the Second Hospital of Dalian Medical University. The wound area ranged from 16.0 cm×8.0 cm to 18.0 cm×12.0 cm. The sustainable skin-stretching device was installed after debridement operation for scalp wound. The wound was stretched from the 3rd day after installation of the device, at a basic speed of 1 mm/d and finished for 3 times on average. During stretching, close attention was paid to the changes in blood flow of the wound margin and the subjective feeling of the patients. When the result was negative in the squeezing and pinching test for wound margin after stretching, the further stretching was stopped, the final stretching state was maintained for 3 days, and the wounds were sutured directly. The wound healing during stretching of sustainable skin-stretching device and the occurrence of complications were observed. The rest wound areas after stretching for 5, 10, 15, and 20 days were measured. The wound healing and hair growth were observed during follow-up. Results: All the wounds of 5 patients was sutured directly after stretching for 19-23 d. There was no tension blister on the margin of wounds during stretching, and the margin of wounds healed well after being sutured without skin necrosis. After stretching treatment for 5-20 d, the wound areas were gradually decreased. During follow-up of 2-11 (4.5±1.5) months, the elasticity, color, feeling, and regenerated hair growth of the stretched scalp tissue were close to those of the surrounding normal skin tissue. The linear scar formed on the margin of wounds, but no scar formed on the wounds. Conclusions: The application of sustainable skin-stretching device can reduce the difficulty in repairing scalp and soft tissue defect, with the regenerated hair growing well after treatment, which is worthy of clinical promotion.

Training primary healthcare workers in China's township hospitals: a mixed methods study

Background

Primary health care (PHC) was a keystone toward achieving universal health coverage and Sustainable Development Goals (SDGs). China has made efforts to strengthen its PHC institutions. As part of such efforts, regular in-service training is crucial for primary healthcare workers (PHWs) to strengthen their knowledge and keep their skills up to date.

Objective

To investigate if and how the existing training arrangements influenced the competence and job satisfaction of PHWs in township hospitals (THs).

Methods

A mixed method approach was employed. We analyzed the associations between in-service training and competence, as well as between in-service training and job satisfaction of PHWs using logistic regression. Interviews were recorded, transcribed, and analyzed using NVivo12 to better understand the trainings and the impacts on PHWs.

Results

The study found that training was associated with competence for all the types of PHWs except nurses. The odds of higher competence for physicians who received long-term training were 3.60 (p < 0.01) and that of those who received both types of training was 2.40 (p < 0.01). PHWs who received short-term training had odds of higher competence significantly (OR = 1.710, p < 0.05). PHWs who received training were more satisfied than their untrained colleagues in general (OR = 1.638, p < 0.01). Specifically, physicians who received short-term training (OR = 1.916, p < 0.01) and who received both types of training (OR = 1.941, p < 0.05) had greater odds of general job satisfaction. The odds ratios (ORs) of general job satisfaction for nurses who received short-term training was 2.697 (p < 0.01), but this association was not significant for public health workers. The interview data supported these results, and revealed how training influenced competence and satisfaction.

Conclusions

Considering existing evidence that competence and satisfaction serve as two major determinants of health workers’ performance, to further improve PHWs’ performance, it is necessary to provide sufficient training opportunities and improve the quality of training.

[Feasibility study of contrast injection scheme based on body mass and iodine flow rate in coronary computed tomography angiography with wide detector CT]

Objective: To investigate the feasibility of coronary computed tomography angiography (CCTA) with the individualized contrast medium injection scheme based on body mass and iodine flow rate by using wide detector CT at 100 kV. Methods: From May 2018 to July 2018,270 patients with clinically suspected coronary artery disease underwent CCTA in TEDA International Cardiovascular Hospital. They were randomly divided into three groups, 90 cases in each group: group A was 0.5 ml/kg, group B was 0.6 ml/kg, the flow rate of contrast medium injection in group A and group B was (body mass×25 mg)/the concentration of contrast medium,group C was 0.8 ml/kg and the flow rate of contrast medium was 5 ml/s. Iohexol (iodine concentration 350 mgI/ml) was used in all three groups. The CT values of the aorta root in the three groups, the CT value of the middle segment of LAD and RCA, SNR、CNR、SD of the aortic root, subjective score of coronary artery and effective dose (ED) were compared. Results: There was no significant difference in CT value of aortic root, CT value of middle LAD and RCA, SNR、CNR、SD of the aortic root, subjective score of coronary artery among group A, group B and group C (all P>0.05). The flow rates of the three groups of contrast agents were statistically different (4.5±0.5 vs 4.5±0.5 vs 5, P=0.015), and there was no statistical difference between group A and group B (P>0.05) but lower than group C (P=0.015); the amount of contrast agent in the three groups was statistically different (32±3 vs 38±4 vs 53±7, P<0.001), group A<B Group<C group; there was no significant difference in ED between the three groups (1.5±0.5 vs 1.5±0.6 vs 1.3±0.6, P=0.613). Conclusions: CCTA imaging with a wide body detector based on a 0.5 ml/kg contrast agent dosage and a flow rate of ((body mass × 25)/350) ml/s individualized injection scheme can ensure the image quality while reducing the total amount of contrast agent and realizing individualized iodine flow rate.

How Can One Strengthen a Tiered Healthcare System through Health System Reform? Lessons Learnt from Beijing, China

How one can reshape the current healthcare sector into a tiered healthcare system with clarified division of functions between primary care facilities and hospitals, and improve the utilization of primary care, is a worldwide problem, especially for the low and middle-income countries (LMICs). This paper aimed to evaluate the impact of the Beijing Reform on healthcare-seeking behavior and tried to explain the mechanism of the change of patient flow. In this before and after study, we evaluated the changes of outpatient visits and inpatient visits among different levels of health facilities. Using the monitored and statistical data of 373 healthcare institutions 1-year before and 1-year after the Beijing Reform, interrupted time series analysis was applied to evaluate the impact of the reform on healthcare-seeking behavior. Semi-structured interviews were used to further explore the mechanisms of the changes. One year after the reform, the flow of outpatients changed from tertiary hospitals to community health centers with an 11.90% decrease of outpatients in tertiary hospitals compared to a 15.01% increase in primary healthcare facilities. The number of ambulatory care visits in primary healthcare (PHC) showed a significant upward trend (P < 0.10), and the reform had a significant impact on the average number of ambulatory care visits per institution in Beijing's tertiary hospitals (p < 0.10). We concluded that the Beijing Reform has attracted a substantial number of ambulatory care visits from hospitals to primary healthcare facilities in the short-term. Comprehensive reform policies were necessary to align incentives among relative stakeholders, which was a critical lesson for other provinces in China and other LMICs.

Health system reforms in China a half century apart: Continuity but adaptation

Well-functioning governance arrangements are an essential, but often overlooked or poorly understood contributor to high quality health systems. Yet governance systems are embedded in institutional structures and shaped by cultural norms that can be difficult to change. We look at a country that has implemented two major health system reforms separated by half a century during which it has undergone remarkable political, economic, and social change. These are the Chinese Patriotic Health Campaign (PHC), beginning in the 1950s, and the New Cooperative Medical Scheme (NCMS), in the 2000s. We use these as case studies to explore how governance arrangements supported the design and implementation of policies implemented on a large scale in these quite different contexts. Drawing on review of archival documents, published literature, and semi-structured interviews with key policy makers, we conclude that few aspects of governance underwent fundamental changes. In both periods, the policy design stage included encouragement of sub-national tiers of government to pilot policy options, accumulate evidence, and disseminate it to others facing similar challenges, all facilitated by clear lines of accountability and a willingness by those at the top of the hierarchy to learn lessons from lower levels. At the implementation stage, rapid scaling up benefitted from leadership by national institutions that could enact regulations and set policy goals and targets for lower tiers of government, evaluating the performance of local government officers in terms of their ability to implement policy, while encouraging local government to pilot innovative measures. These findings highlight the importance of a detailed understanding of governance and how it is shaped by context, demonstrating continuity over long periods even at times of major social, political, and economic change. This understanding can inform future policy development in China and measures to strengthen governance aspects of reforms elsewhere.

Rheological behavior of molecular vs network chalcogenide supercooled liquids

The viscoelastic behavior of supercooled glass-forming liquids along the binary join As₄S₃-GeS₂ with As₄S₃ contents varying from 81.25 to 9 mol. % and correspondingly with structures varying from predominantly molecular to a three-dimensional tetrahedral network is studied by small-amplitude oscillatory shear parallel plate rheometry. The storage shear modulus G' shows a scaling behavior of G'(ω) ∼ ωⁿ in the terminal (low-frequency) regime, where n varies between 1 and 2 and shows an increasingly anomalous departure from the expected value of 2 (Maxwell scaling) with increasing molecule content. A concomitant departure from the Maxwell scaling is also observed for the loss modulus G″ at frequencies above the G'-G″ crossover. On the other hand, the variation in the phase angle δ with the complex modulus indicates that the molecular liquid does not display a purely viscous response even at the lowest frequencies. These results, combined with an analysis of the relaxation spectra of these liquids, suggest that the anomalous behavior of molecular liquids may be linked to their rather broad relaxation spectrum and the presence of slow relaxation processes associated with molecular clusters. Additionally, these liquids are also characterized by a wide high-frequency plateau in the relaxation spectral density that can be linked to the rotational dynamics of the constituent molecules. Such fundamental differences between the rheological behavior of molecular and network liquids may explain the significantly higher fragility of the former.

Doppler coherence imaging of scrape-off-layer impurity flows in the HL-2A tokamak

A new Doppler coherence imaging spectroscopy interferometer has been developed on the HL-2A tokamak for the scrape-off-layer impurity flow measurement. Its spatial resolution is estimated to be up to ∼0.8 mm in the horizontal direction and ∼9 mm in the vertical direction, with a field of view of ∼34°. Its typical temporal resolution is about 1 ms. This salient feature allows for time-resolved 2D measurements in short-time phenomena on HL-2A, such as edge localized modes. Group delay and interference fringe pattern were calibrated with a dedicated calibration system. The robustness of group delay calibration and the feasibility of the extrapolation model for fringe pattern calibration are demonstrated. In this paper, we report the details of the optical instruments, calibration, and the initial experimental results of this Doppler coherence imaging spectroscopy interferometer.

microRNA-144-3p suppresses human neuroblastoma cell proliferation by targeting HOXA7

OBJECTIVE

Dysregulation of microRNAs (miRNAs) expression often resulted in abnormal cell behaviors. It has been demonstrated that miRs may serve as oncogenic or tumor suppressive functions in tumor. We investigated whether or not miR-144-3p has a role in the progression of human neuroblastoma (NB).

PATIENTS AND METHODS

46 NB patients were enrolled in this study. miR-144-3p expression in NB tissues and cell lines was detected by reverse transcription-quantitative polymerase chain reaction. The biological functions of miR-144-3p in NB were detected by cell counting kit-8 assay, flow cytometry assay, and wound-healing assay. Luciferase activity assay and Western blot assay were performed to validate the direct targets of miR-144-3p.

RESULTS

We found miR-144-3p expression was reduced in NB tissues and cell lines and resulted in the stimulation of cell proliferation, cell cycle progression, and cell migration in vitro. Furthermore, we validated homeobox protein A7 (HOXA7) as a direct target of miR-144-3p.

CONCLUSIONS

Taken together, these results demonstrated the tumor suppressive role of miR-144-3p in NB and may advance the understanding of the underlying mechanisms of miR-144-3p and HOXA7 in NB.

The role of macrophages during breast cancer development and response to chemotherapy

Macrophages play an important role in the immune system as a key host defense against pathogens. Non-polarized macrophages can differentiate into pro-inflammatory classical pathway-activated macrophages or anti-inflammatory alternative pathway-activated macrophages, both of which play central roles in breast cancer growth and progression in a process called polarization of macrophages. Classical pathway-activated and alternative pathway-activated macrophages can transform into each other and their transformational properties and orientation are determined by cytokines in the tumor microenvironment. Tumor-associated macrophages display many functions, such as tissue reforming, participating in inflammation and tumor growth in breast cancer progression. Some cytokines, such as interleukins and transcriptional activators, reside in the tumor microenvironment and influence tumor-associated macrophages. Chemotherapy is a common treatment for breast cancer and macrophages play an important role in mammary tumor cell migration, cancer invasion, and angiogenesis. This review summarizes the activities of tumor-associated macrophages in the mammary tumor, chemotherapeutic processes and some potential strategies for breast cancer therapy.

[Value of lenvatinib for the treatment of advanced hepatocellular carcinoma]

Objective: To observe the safety and efficacy of lenvatinib for the treatment of medium-advanced hepatocellular carcinoma. Methods: A total of 36 patients with medium-advanced hepatocellular carcinoma from the First Medical Center of the Chinese PLA General Hospital were retrospectively analyzed from January 2018 to May 2019. All patients had shown tumor progression after at least 2 sessions of TACE. The patients were consisted of 30 males and 6 females with age range of 35 to 76 (54±10) years. Patients received orally administered lenvatinib at a dose of 12 mg once daily for patients ≥ 60 kg and 8 mg once daily for patients<60 kg. According to modified RECIST criteria the tumor response, disease control rate, overall survival and progression free survival were evaluated once every 6-8 weeks. The adverse events were recorded. Results: No patient was in complete response, 2 cases (5.7%) in partial response, and 5 cases (14.3%) in stable disease, respectively. Disease control rate was 20.0% (7/35), the overall survival was 11.5 months, and the progression free survival was 5.3 months. The overall incidence of adverse events was 66.7% (24/36). The most frequent adverse events were hypertension, proteinuria, hand-foot skin reaction and abdominal distension. Conclusion: Lenvatinib can extend the overall survival in a percentage of medium-advanced hepatocellular carcinoma patients who were unresectable and refractory to TACE. Although the incidence of adverse events is high, most of them are mild and reversible.

The significance of IL-28B and CK-18 M30 levels in the diagnosis of non-alcoholic steatohepatitis in SD rats

AIMS

To investigate the role of IL-28B and CK-18 M30 in the diagnosis of non-alcoholic steatohepatitis (NASH) in rats.

METHODS

The rat NASH model was constructed by high-fat diet feeding and confirmed by liver tissue pathology analysis. The CK-18 M30, IL-28B, liver function and blood lipid were detected. The pathology of liver tissues was observed by H&E staining. The ROC curves of liver pathological scores, IL-28B, and CK-18 M30 were plotted and the sensitivity/specificity of each index was calculated.

RESULTS

The liver tissue pathology at the end of the 12th week met NASH diagnostic criteria. The liver pathological scores of NASH model were higher than those of the control group (P < 0.05). Compared with the control group, the body weight of rats in the NASH group was lower (P < 0.05) and the liver index was higher (P < 0.05). Moreover, the serum levels of alanine aminotransferase, triglyceride, low-density lipoprotein, total cholesterol and CK-18 M30 in the NASH group were higher (P < 0.05) and positively correlated with liver pathological scores (P < 0.05), but IL-28B in serum and liver tissue was lower (P < 0.05) and negatively correlated with liver pathological scores (P < 0.05). According to the ROC curves, the sensitivity/specificity of each index was shown as following: liver pathological scores (1.000/1.000), IL-28B of liver tissue (1.000/0.857), serum CK-18 M30 plus IL-28B (0.857/1.000), serum IL-28B (0.857/0.857) and serum CK-18 M30 (1.000/0.857).

CONCLUSIONS

IL-28B level is related to the pathological changes of livers in SD rats during the development of NASH. The combination of serum CK-18 M30 level and serum IL-28B level may be a promising non-invasive detection method for the diagnosis of NASH.

Job satisfaction, burnout, and turnover intention among primary care providers in rural China: results from structural equation modeling

BACKGROUND

Low job satisfaction, severe burnout and high turnover intention are found to be prevalent among the primary care providers (PCPs) in township health centers (THCs), but their associations have received scant attention in the literature. In light of this, this study aims to examine the relationships between job satisfaction, burnout and turnover intention, and explore the predictors of turnover intention with a view to retaining PCPs in rural China.

METHODS

Using the multistage cluster sampling method, a cross-sectional survey was conducted in Shandong Province, China. 1148 PCPs from 47 THCs participated in this study. Job satisfaction, burnout and turnover intention were measured with a multifaceted instrument developed based on the existing literature, the Maslach Burnout Inventory and the participants' responses to a Likert item drawn from the literature, respectively. The relationships of the three factors were examined using Pearson correlation and structural equation modeling, while the predictors of turnover intention were investigated using multivariate logistic regression.

RESULTS

The subscale that the PCPs were most dissatisfied with was job rewards (95.12%), followed by working environment (49.65%) and organizational management (47.98%). The percentages of the PCPs reporting high-levels of emotional exhaustion, depersonalization and reduced personal accomplishment were 27.66, 6.06, and 38.74%, respectively. About 14.06% of the respondents had high turnover intention. There was a significant direct effect of job satisfaction on burnout (γ = - 0.52) and turnover intention (γ = - 0.29), a significant direct effect of burnout on turnover intention (γ = 0.28), and a significant indirect effect (γ = - 0.14) of job satisfaction on turnover intention through burnout as a mediator. Work environment satisfaction, medical practicing environment satisfaction, and organizational management satisfaction proved to be negative predictors of turnover intention (p < 0.05), whereas reduced personal accomplishment was identified as a positive predictor (p < 0.05).

CONCLUSIONS

Plagued by low job satisfaction and severe burnout, the PCPs in rural China may have high turnover intentions. Job satisfaction had not only negative direct effects on burnout and turnover intention, but also an indirect effect on turnover intention through burnout as a mediator. Targeted strategies should be taken to motivate and retain the PCPs.

Governance function analysis of the Patriotic Health Movement in China

Background

Health system governance is critical to the operation of a country's health system and its overall performance. This study analyzes the role of health system governance in driving health policy innovation and effective implementation.

Methods

A retrospective review is applied to collect, analyze and synthesize information from publications and policy documents relevant to the implementation of a typical health policy, the Patriotic Health Movement.

Results

The analysis of governance highlighted a number of features underpinning this policy. These included highest authority prioritizing health system development, specific health policies being prioritized within the national development agenda, strong political will to promote the policies drawing on the advantages of the highly hierarchal administrative system in China, and accumulating evidence from local experience to support policy making. It was also found that the formation of these governance practices and how they drove policy innovation and implementation were both closely related to the political and socio-economic contexts in China.

Conclusion

Given that many low- and middle- income countries are strengthening their health systems aimed at UHC, this study demonstrates that along with drawing lessons from health policies or interventions, addressing factors in each governance domain is critical in adapting the policy design to other settings and the effective operation of policies in other settings.

Motivating factors on performance of primary care workers in China: a systematic review and meta-analysis

OBJECTIVE

Although China has made remarkable progress in strengthening its primary healthcare system, lack of well-performed primary health workforce is still the bottleneck of deepening the reform. The objective of this review is to understand the current profile of Chinese primary care workers (PCWs) and their motivating factors of performance and propose targeted policy suggestions on improving their work performance.

DESIGN

Systematic review.

METHODS

A systematic search of PubMed and MEDLINE was conducted to identify articles published from January 1, 2000, to June 2, 2018. Quality assessment and data extraction for the studies closely relevant to performance of PCWs in China were conducted by two reviewers independently. A preliminary framework containing different levels of factors influencing PCWs' motivation based on existence, growth and relatedness (ERG) theory guided the synthesis analysis. In addition, we used a random-effects model to pool individual studies on job satisfaction and estimate the overall job satisfaction of PCWs.

RESULTS

A total of 36 articles were included; 16 (23 882 participants) in the meta-analysis. Regarding the individual level of motivation, 3 overarching themes and 12 subthemes were developed. The subthemes of financial incentives, career advancement and work itself were frequently mentioned and have more influences on PCWs' performance. Moreover, the healthcare system reform policies have inevitable and complex impacts on different levels of human needs, and then influences on the motivation and performance of PCWs. Meta-analysis showed that the overall job satisfaction score among PCWs was 3.30, just reaching a satisfied rating and varied in different regions.

CONCLUSIONS

This study suggests low work satisfaction among PCWs in China, with financial incentives and career advancement being two most important motivating factors. Efforts to improve the work performance in PCWs should give priority to these motivating factors and systematically take into account the health policy's impacts on performance of PCWs.

Contextual Factors Associated with Burnout among Chinese Primary Care Providers: A Multilevel Analysis

Burnout is a common and growing phenomenon in the health care setting. The objective of the present study is to examine contextual factors in the workplace associated with burnout among primary care providers (PCPs) in Shandong Province, China. A cross-sectional survey was conducted among 951 PCPs nested within 48 primary health institutions (PHIs). Burnout was measured using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). We used two-level random intercept linear regression models to examine individual- versus workplace-level risk factors for burnout. The result revealed that 33.12%, 8.83% and 41.43% PCPs were experiencing a high degree of emotional exhaustion (EE), depersonalization (DP) and low personal accomplishment (PA). In multilevel analysis, the most significant and common individual-level predictors of burnout were lack of perceived work support and autonomy. At the institutional level, workload was positively related to EE (odds ratio (OR): 6.59; 95% confidence interval (CI): 3.46-9.72), while work support was related to higher PA (OR: 3.49; 95% CI: 0.81-6.17). Greater attention should be paid to the influence of the work environment factors (workload and work support) to prevent burnout. Strategies such as increasing human resources allocated to PHIs and establishing a supportive work environment are encouraged to prevent and reduce burnout among PCPs in China.

Transarterial embolisation with bleomycin and N-butyl-2-cyanoacrylate -Lipiodol mixture for symptomatic polycystic liver disease: preliminary experience

AIMS

To evaluate the therapeutic effect and safety of transarterial embolisation using a bleomycin-Lipiodol mixture and N-butyl-2-cyanoacrylate (NBCA)-Lipiodol mixture (BNL) for the treatment of polycystic liver disease (PLD).

MATERIALS AND METHODS

From June 2012 to July 2018, a total of consecutive 14 symptomatic patients (13 women and 1 man; mean age, 49.3±9.9 years) with PLD were referred and underwent transcatheter arterial embolisation (TAE) with BNL.

RESULTS

Technical success was achieved in all cases. PLD-related severe symptoms were improved remarkably in 13 of the treated patients. The mean maximum abdominal circumference decreased significantly from 100.6±9.4 to 94.9±9.1 cm (p<0.01). The total liver volume decreased significantly compared with pre-TAE in 13 patients at 6-12 months after TAE. It decreased from 9,776±2,219 to 8,303±2,009 cm³ (p<0.01). There were no major complications associated with the procedure.

CONCLUSION

TAE with the bleomycin-Lipiodol mixture and NBCA-Lipiodol mixture may be an effective method for treating symptomatic PLD patients, with improvement of symptoms and shrinkage of cyst volume.

Job satisfaction of the primary healthcare providers with expanded roles in the context of health service integration in rural China: a cross-sectional mixed methods study

OBJECTIVE

Against the backdrop of integrating public health services and clinical services at primary healthcare (PHC) institutions, primary healthcare providers (PCPs) have taken on expanded roles. This posed a potential challenge to China as it may directly impact PCPs' workload, income, and perceived work autonomy, thus affecting their job satisfaction. This study aimed to explore the association between the expanded roles and job satisfaction of the PCPs in township healthcare centers (THCs), the rural PHC institutions in China.

METHODS

A cross-sectional study using mixed methods was conducted in 47 THCs in China's Shandong province. Based on a sample of 1146 PCPs, the association between the proportion of PCPs' working time spent on public health services and PCPs' self-reported job satisfaction was estimated using the logistic regression. Qualitative data were also collected and analyzed to explore the mechanism of how the expanded roles impacted PCPs' job satisfaction.

RESULTS

One hundred eighty-four physicians and 146 nurses undertook increased work responsibilities, accounting for 15.91% and 12.61% of the total sample. For those spending 40-60%, 60-80%, and more than 80% of the working time providing public health services, the time spent on public health was negatively associated with job satisfaction, with the odds ratio being 0.199 [0.067-0.587], 0.083 [0.025-0.276], and 0.030 [0.007-0.130], respectively. Qualitative analysis illustrated that a majority of the PCPs with expanded roles were dissatisfied with their jobs due to the heavy workload, the mismatch between the income and the workload, and the low level of work autonomy. PCPs' heavier work burden was mainly caused by the current public health service delivery policy and the separation of public health service delivery and regular clinical services delivery, a significant challenge undermining the efforts to better integrate public health services and clinical services at PHC institutions.

CONCLUSION

The current policies of adding public health service delivery to the PHC system have negative impacts on PCPs' job satisfaction through increased work responsibilities for PCPs, which have led to low work autonomy and the mismatch between the income and the workload. The fundamental reason lies in the fragmented incentives and external supervision for public health service delivery and clinical service delivery. Policy-makers should balance the development of clinic and public health departments at the institutional level and integrate their financing and supervision at the system level so as to strengthen the synergy of public health service provision and routine clinical service provision.

[A comparative study of prostatic artery embolization in the treatment of benign prostatic hyperplasia with different prostatic volume]

Objective: To compare the efficacy of prostatic artery embolization (PAE) in the treatment of patients with benign prostatic hyperplasia (BPH) with different prostatic volume (PV). Methods: In this single-center, retrospective study, 137 patients, mean age (70±11) years, range 50-89 years, undergoing PAE for BPH between January 2015 and May 2017 in Chinese PLA General Hospital were involved and divided into three groups according to the PV (group A, >80 ml; group B, 40-80 ml; group C, <40 ml). The changes of international prostate symptoms (IPSS) score, quality of life (QoL) score, and maximum urinary flow rate (Q(max)) were compared among the three groups at 1, 6, and 12 months post-PAE. Correlation between the proportion of prostate ischemia at 1 month post-PAE and the proportion of PV reduction at 12 month post-PAE were analyzed, also the correlation between both of them with IPSS and QoL score were analyzed, respectively. Results: Mean baseline prostate volumes were 110 ml in group A (n=62), 67 ml in group B (n=47) and 33 ml in group C (n=28). At 12 months post-PAE, the outcomes of IPSS score and Q(max) in group A were better than those in group B and C (all P<0.05).The proportion of prostate ischemia at 1 month post-PAE and proportion of PV reduction at 12 month post-PAE in group A, B, and C were 61.4%, 49.3%, 38.0%, and 47.3%, 29.3%, 24.6%, respectively. The proportion of prostate ischemia in group A was larger than that in group B and C (P=0.049, 0.004), also the proportion of PV reduction in group A was greater than that in group B and C (P<0.01). The proportion of prostate ischemia at 1 month post-PAE in all three groups were positively correlated with the proportion of PV reduction at 12 month post-PAE (r=0.699, P=0.024; r=0.719, P=0.019; r=0.821, P=0.004), and there were positive correlations between both of them and the improvement of IPSS score at 12 month post-PAE (0.5<r<1.0, all P<0.05), while no correlation with the improvement of QoL score. Conclusions: Patients with BPH with PV larger than 80 ml are more suitable for PAE. The proportion of prostate ischemia and prostate volume reduction after PAE can predict the efficacy of PAE.

Effects of gangliosides on expressions of caspase-3 and NGF in rats with acute spinal cord injury

OBJECTIVE

To investigate the effects of ganglioside [monostalotetra-hexosylganglioside (GM1)] on the expressions of caspase-3 and nerve growth factor (NGF) in rats with acute spinal cord injury (SCI).

MATERIALS AND METHODS

Male Sprague- Dawley (SD) rats were selected and randomly divided into Sham group, SCI group and GM1 administration group. The rats in Sham group, SCI group and GM1 group were subjected to behavioral examinations of Basso Beattie Bresnahan (BBB) and oblique-plate test at 1, 7 and 14 d after operation. The content of methylene dioxyamphetamine (MDA) and the activity of superoxide dismutase (SOD) of every rat in each group were measured by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence staining assay was used to detect the expression levels of caspase-3 and NGF of rats in each group. The messenger ribonucleic acid (mRNA) and protein expressions of caspase-3 and NGF of rats in Sham group, SCI group and GM1 group were detected using reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blotting assay.

RESULTS

The BBB scores and the results of oblique-plate test in Sham group, SCI group and GM1 group at 1, 7 and 14 d showed that the BBB scores and the results of oblique-plate test of rats in each group were significantly decreased at 1 d after SCI, and had different degrees of recovery at 7 and 14 d after injury. The results of ELISA detection revealed that SCI group had increased content of MDA and clearly decreased activity of SOD in comparison with Sham group; at the same time, MDA content in GM1 group was overtly lower than that in SCI group, while SOD activity was enhanced evidently in GM1 group compared with that in SCI group. According to immunofluorescence assay, significantly increased expression of caspase-3 and distinctly decreased expression of NGF were found in SCI group. However, this phenomenon was significantly reversed by GM1. RT-PCR and Western blotting assay severally proved that the mRNA and protein expressions of caspase-3 were raised in SCI group and decreased clearly after the administration of GM1; while the mRNA and protein expressions of NGF was significantly reduced in SCI group and overtly elevated after the administration of GM1. ANOVA showed that there were statistically significant differences in expressions of caspase-3 and NGF among Sham group, SCI group and GM1 group (p<0.05).

CONCLUSIONS

GM1 has an evident effect on the expressions of caspase-3 and NGF in rats with acute SCI, and is able to down-regulate the expression of caspase-3 and up-regulate the expression of NGF, so as to achieve its therapeutic effect on SCI.

The interaction effect of health insurance reimbursement and health workforce on health care-seeking behaviour in China

OBJECTIVE

In China, patients generally seek health care at high-level hospitals, which is leading to escalating medical costs and overloaded hospitals. Some studies have suggested that the health system is an important factor influencing individuals' health care-seeking behaviour; however, this association has not been studied in much depth. We therefore examined the impact of the health system (in terms of the interaction between health insurance reimbursement and health workforce) on health care-seeking behaviour.

METHODS

Drawing on national survey data from 2008 and 2013, we linked individual-level data on choice of health care providers (our index of health care-seeking behaviour) with county-level data on the health workforce and health insurance. We then constructed a multilevel multinomial logistic model to examine the impacts of health insurance reimbursement (indexed as average reimbursement rate [ARR]) and the health workforce (number of registered physicians per 1000 population) at county hospitals and primary health care institutions (PHCs) on choice of inpatient care providers.

RESULTS

Increases in ARR at county hospitals were associated with a greater probability of visiting such hospitals (relative risk ratio [RRR] = 1.23), and this positive impact was even greater in county hospitals with higher physician densities (RRR = 2.76). Greater ARR in PHCs was associated with a 73% lower probability of visiting municipal- and higher-level hospitals; increasing ARR was associated with an even lower probability when physician density in PHCs was considered (RRR = 0.09).

CONCLUSION

Increases in the health insurance reimbursement and health workforce are necessary to improve health care access and thereby health care-seeking behaviour. Thus, comprehensive health system reform is necessary.

Abstract P4-06-30: Adipose PD-L1 modulates checkpoint blockade immunotherapy efficacy in breast cancer

Programmed death-ligand 1 (PD-L1) and its receptor programmed cell death protein 1 (PD-1) play important roles in modulating antitumor immune response and are targeted by checkpoint blockade immunotherapy. While PD-L1 expression in both tumor and host cells is associated with antitumor therapeutic efficacy, the exact contribution of PD-L1 in various tissue and cell compartments to antitumor immune response remains to be elucidated. Here we show that PD-L1 expression is markedly elevated in human and mouse mature adipocytes compared to their preadipocyte counterparts. When co-cultured with mouse splenocytes in vitro, adipocytes prevent anti-PD-L1 antibody from activating CD8+T cells. Genetic ablation of adipose PD-L1 obliterates the inhibitory effect of adipocytes on anti-PD-L1 antibody. Conversely, enforced PD-L1 expression in preadipocytes confers the antibody-inhibitory activity. GW9662, a pharmacologic inhibitor of peroxisome proliferator-activated receptor γ (PPARγ) in adipogenesis, selectively reduces PD-L1 expression in mouse adipose tissue. The same PPARγ antagonist also enhances the antitumor efficacy of checkpoint blockade antibodies for treating multiple mammary tumors. Our findings provide a previously unappreciated approach to bolster anticancer immunotherapy efficacy and suggest a mechanism for the role of adipose tissue in breast cancer progression.

[Transarterial chemoembolization with bleomycin treatment for moderate-advenced hepatocellular carcinoma]

Objective: To investigate the safety and efficacy of transarterial chemoembolization (TACE) using bleomycin for the treatment of medium-advanced hepatocellular carcinoma (HCC). Methods: Between December 2015 and December 2017, a total of 160 patients from the Chinese PLA General Hospital with moderate-advanced HCC whose diagnoses were confirmed by pathology or clinical imaging and were in accord with the Barcelona Clinic Liver Cancer (BCLC) staging criteria were prospectively analyzed.All patients had shown persistent viable tumor or tumor progression after at least 2 sessions of TACE.All patients included 135 males and 25 females , age 35-74 (57±8)years, were randomly divided into two groups, the treatment group: TACE procedures consisted of bleomycin+ pirarubicin+ oxaliplatin+ fluorouracil, the control group: pirarubicin+ oxaliplatin+ fluorouracil, and according to modified RECIST criteria the tumor response was evaluated once every 4-6 weeks, survival analysis was performed, overall survival and progression free survival were evaluated.the adverse events were recorded. Results: Response rate of the treatment group was 27.5%(22/80), the median progression free survival(mPFS)was 5.8 months, and the median overall survival (mOS) was 8.1 months.Response rate of the control group was 7.5%(6/80), mPFS of 2.9 months, and mOS of 4 months.The differences in mPFS and in mOS between the two groups were statistically significant (P=0.009, 0.002 respectively), and no serious adverse occurred. Conclusion: It is suggested that transarterial chemoembolization with bleomycin is safe and effective for medium-advenced HCC.
