- Abstract
Background: Chronotropic incompetence (CI) severely limits exercise tolerance due to impaired heart rate responses. This study investigated whether pacemaker with closed-loop stimulation (DDD-CLS) pacing, which provides rate acceleration in response to exertion, could enhance lung function and cardiopulmonary capacity compared pacemaker without CLS pacing in patients with CI., Methods: This randomized crossover trial included 32 patients with CI who were compared to each CLS and DDD pacing over 2 months. Spirometry was used to assess the forced vital capacity (FVC). Cycling-based cardiopulmonary exercise testing (CPET) measured peak oxygen uptake (peak VO
2 )., Results: DDD-CLS pacing yielded significantly higher FVC (2.2 ± 0.8 L) versus DDD pacing (2.0 ± 0.7 L), p = 0.036, a 3.2% improvement. Moreover, those in the DDD-CLS mode showed a significantly higher FEV1 of 1.8 ± 0.6 L compared to the DDD mode of 1.7 ± 0.5 L (p = 0.03). Compared with DDD pacing, DDD-CLS pacing also achieved superior peak VO2 (14.9 ± 4.0 vs 12.2 ± 3.7 mlO2 /kg/min, p < 0.001) and peak heart rate (106.9 ± 9.7 vs 98.3 ± 19.8 bpm, p = 0.013). DDD-CLS and DDD pacing modes showed significant correlations between FVC and peak VO2 and between peak VO2 and peak heart rate during CPET., Conclusions: Compared with DDD mode, DDD-CLS pacing provided physiological chronotropic support to improve cardiopulmonary function during exertion, which enhanced lung capacity in patients with CI., Competing Interests: Declaration of competing interest None declared., (Copyright © 2024 Formosan Medical Association.

- Abstract
Important concepts in leadership management related to the field of medical care management include servant leadership, charismatic leadership, and transformational leadership. Since the 2020 emergence of the coronavirus pandemic, the world has faced the immediate challenges of epidemic prevention and control. Although national government and medical system officials as well as scholars have weighed in on this issue, their leadership does not appear to line up the core ideas of leadership. Daft and Lengel (2000) examined the influence of fusion leadership on individuals and organizations. The fusion of many nuclei of leadership intentions will produce great power and influence. To elucidate the concept of integrated leadership for individuals and organizations in the post-pandemic healthcare system, this paper summarizes the defining characteristics of fusion leadership based on the conceptual analysis method of Walker and Avant (2019). Concurrently, we confirm the antecedents and consequences of fusion leadership, use different cases to illustrate the analysis, and share the reference indicators and measurements of fusion leadership to provide a reference for healthcare system administrators.

- Abstract
Non-alcoholic fatty liver disease(NAFLD), as a metabolic stress liver injury disease, is one of the most common chronic liver diseases, which seriously threatens people's health. The pathogenesis of NAFLD is very complex. A large number of studies show that the hepatic mitochondrial dysfunction leads to the disorder of hepatic glucose and lipid metabolism, oxidative stress, and inflammation, thus inducing hepatocyte apoptosis, which plays an important role in the progression of NAFLD. In recent years, researchers have begun to focus on developing drugs that slowed the progression of NAFLD by regulating the hepatic mitochondrial function. Chinese medicine has a good curative effect on the treatment of NAFLD, with the advantages of high safety and few side effects. Various studies have shown that Chinese medicine prevented and treated NAFLD by regulating the mitochondrial function. Therefore, this paper summarized the relationship between NAFLD and mitochondria, and the mechanism of Chinese medicine(single Chinese medicine, Chinese medicine monomer, and Chinese medicine compound prescription) in the prevention and treatment of NAFLD by regulating mitochondrial function. This paper is expected to provide references for clinical application of traditional Chinese medicine in the treatment of NAFLD by regulating mitochondrial function.

- Abstract
The article describes the author's nursing experience providing psychiatric homecare to a patient with chronic schizophrenia using the concept of resilience. Holistic nursing assessments were conducted via clinical observations during home visits every two weeks from May 24th to September 20th, 2018. Through these assessments, the main health problems of the patient were defined as ineffective self-health management, ineffective coping skills, and insufficient resilience. The nursing interventions implemented were designed to establish the patient's capacity to effectively and correctly self-manage health status, achieve emotional accommodation, and reduce parent-child conflicts. In order to enhance the resilience of the patient, the patient was guided to review important support resources over the course of illness, to detect the barriers of returning society, to apply the beneficial skills of health management, and then extend the status of employment and to enhance self-fulfillment.

- Abstract
Hydrogen sulfide (H
2 S), an endogenous signaling gaseous molecule, is involved in various physiological activities, including vessel relaxation, regulation of cellular bioenergetics, inflammation, and angiogenesis. By using xenograft orthotopic implantation of prostate cancer PC3 cells and subsequently comparing bone metastatic with primary tumor-derived cancer cells, we find that H2 S-producing enzyme cystathionine γ-lyase (CTH) is upregulated in bone-metastatic PC3 cells. Clinical data further reveal that the expression of CTH is elevated in late-stage prostate cancer patients, and higher CTH expression correlates with poor survival from The Cancer Genome Atlas (TCGA) prostate cancer RNA-seq datasets. CTH promotes NF-κB nuclear translocation through H2 S-mediated sulfhydration on cysteine-38 of the NF-κB p65 subunit, resulting in increased IL-1β expression and H2 S-induced cell invasion. Knockdown of CTH in PC3 cells results in the suppression of tumor growth and distant metastasis, while overexpression of CTH in DU145 cells promotes primary tumor growth and lymph node metastasis in the orthotopic implanted xenograft mouse model. Together, our findings provide evidence that CTH generated H2 S promotes prostate cancer progression and metastasis through IL-1β/NF-κB signaling pathways., (© 2019 The Authors.

- Abstract
The early onset breast cancer patients (age ≤ 40) often display higher incidence of axillary lymph node metastasis, and poorer five-year survival than the late-onset patients. To identify the genes and molecules associated with poor prognosis of early onset breast cancer, we examined gene expression profiles from paired breast normal/tumor tissues, and coupled with Gene Ontology and public data base analysis. Our data showed that the expression of GAS7b gene was lower in the early onset breast cancer patients as compared to the elder patients. We found that GAS7 was associated with CYFIP1 and WAVE2 complex to suppress breast cancer metastasis via blocking CYFIP1 and Rac1 protein interaction, actin polymerization, and β1-integrin/FAK/Src signaling. We further demonstrated that p53 directly regulated GAS7 gene expression, which was inversely correlated with p53 mutations in breast cancer specimens. Our study uncover a novel regulatory mechanism of p53 in early onset breast cancer progression through GAS7-CYFIP1-mediated signaling pathways.

- Abstract
This study quantified five perfluorocarboxylic acids (PFCAs) and two perfluorosulfonic acids in cereals, meats, seafood, eggs, pork liver, and milk in Taiwan using ultra-performance liquid chromatography-tandem mass spectrometry and evaluated the dietary exposure of the general population and pregnant women using per capita consumption and a questionnaire, respectively. Perfluorooctanoic acid (PFOA) and PFCAs of 10-12 carbons were found in almost all of the samples in considerable concentrations in rice and pork liver, reaching as high as 283 ng/g (PFOA in pork liver); the levels are two to three orders of magnitude higher than previous reports. Perfluorooctane sulfonate (PFOS), the most frequently mentioned perfluoroalkyl substance, was rarely detected in many food items (detection frequencies <20% in rice, flour, pork, chicken, salmon, squid, eggs, and milk) at <0.4 ng/g, except for beef, pork liver and some seafood (detection frequencies: 100%, GMs: 0.05-3.52 ng/g). Compared to populations in Western countries, people in Taiwan are exposed to much more perfluorohexanoic acid, PFOA, perfluorodecanoic acid, and perfluoroundecanoic acid (11.2, 85.1, 44.2, and 4.45 ng/kg b.w./day, respectively), mainly due to the higher contaminations in food. The exposure of 8.0 μg PFOA/person/day in the 95 percentile of pregnant women was due to their frequent consumption of pork liver., (Copyright © 2018. Published by Elsevier B.V.)

- Abstract
Aim: Religious social networks are well known for their capacity to improve individual health, yet the effects of friendship networks within the Buddhist context remain largely unknown. The present study aimed to compare health status and social support in community-dwelling older adults according to their level of Buddhist social network (BSN) involvement, and to examine the association between BSN involvement and functional health among older adults., Methods: A cross-sectional survey was carried out among 427 Buddhist community-dwelling older adults aged ≥60 years in Nakhon Pathom, Thailand. Data were collected from home-based personal interviews using a structured questionnaire. Health status was defined according to the measures of basic and advanced activities of daily living (ADL), the 15-item Geriatric Depression Scale and subjective quality of life. Perceived social support was assessed across the four dimensions of tangible, belonging, emotional and information support. Multiple logistic regression was used for analysis., Results: Older adults with BSN involvement reported better functional, mental and social health status, and perceived greater social support than those without BSN involvement. In addition, BSN involvement was positively associated with independence in basic and advanced ADL. After adjusting for age, sex, education, income, morbidity and depressive symptoms, BSN showed a strong association with advanced ADL and a weak association with basic ADL., Conclusion: The results show that involvement in BSN could contribute positively to functional health, particularly with regard to advanced ADL. Addressing the need for involvement in these networks by older adults might help delay functional decline and save on healthcare costs., (© 2014 Japan Geriatrics Society.)

- Abstract
We assessed the occurrence of nonylphenol (NP) and bisphenol A (BPA) in tap water supplied through polyvinyl chloride (PVC), stainless steel, and galvanized pipes. Water samples were collected from selected households in Taipei and Kaohsiung (Northern and Southern Taiwan, respectively) in different seasons to elucidate the effects of pipeline materials and ambient temperatures on NP and BPA concentrations in tap water. We detected higher concentrations of NP in tap water from households using PVC pipes (64-195 ng/L) than from those using stainless steel pipes (17-44 ng/L) and galvanized pipes (27-96 ng/L). To verify that water can absorb NP and BPA from PVC pipes, we sealed Milli-Q and tap water in PVC and stainless steel pipes to assess the potential release of NP and BPA from the pipes into the water. Both NP and BPA concentrations initially increased with contact time in the PVC pipes, and the concentration profiles during the retention appeared to be more strongly affected by ambient temperatures. Concentration variations in the stainless steel pipes were smaller than those in the PVC pipes.

- Abstract
Depression in older adults erodes their health, quality of life and the economy. Existing interventions are not feasible for broad application at the community. Postcard intervention only requires a few resources, and previous studies have shown its effectiveness for patients following drug overdose, self-harm and hospitalisation for major depression. The purpose of the present study is to evaluate the effectiveness of a postcard intervention. Participants were community-dwelling individuals, aged 65 or older, who eat meals alone and with the score of 4 or higher on the 15-item Geriatric Depression Scale (GDS-15). We enrolled 184 eligible participants, with 93 in the intervention and 91 in the control arm. Postcards were sent to participants once a month for eight months. Primary outcome was the GDS-15 score at post-intervention. Secondary outcomes were quality of life and activities of daily living. There was no significant difference in primary and secondary outcomes between completers of the intervention and the control arm. However, most of the participants who received intervention thought the intervention was effective. The postcard intervention for depression in community-dwelling elderly people in Japan is neither feasible nor effective. However, the descriptive results suggest that the intervention may be effective given different parameters., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Aim: The 25-item Kihon Checklist (KCL) is the official self-administered questionnaire tool to screen frail older adults, consisting of seven categories: physical strength, nutritional status, oral function, houseboundness, cognitive function, depression risk and a score of more than 9 out of 1-20 items. The aim of the present study was to evaluate the relationships between each category of the KCL and newly certified cases under the Long-Term Care Insurance (LTCI) in Japan during 24 months., Method: The study population consisted of 883 community-dwelling adults aged 65 years or older uncertified by LTCI completing a questionnaire, which included the KCL and scales of basic/advanced activities of daily living (ADL), quality of life (QOL), and depressive symptoms. The participants were categorized into the risk or non-risk group depending on the official criteria of each KCL category. The outcome was the incidence of newly certified cases by LTCI during 24 months. The difference between the risk and non-risk group was analyzed by Cox regression hazard models., Results: Scores in basic/advanced ADL and QOL were higher, and the score in the geriatric depression scale was lower in the non-risk than the risk group in KCL criteria. In men, the incidence of newly certified cases was higher in the risk group of the physical strength category after adjusting for age and the other categories of the KCL., Conclusion: The physical strength category in men was the only significant predictor of the incidence of newly certified cases by LTCI. Further studies are required to improve the assessment item of cognitive function in KCL under LTCI., (© 2014 Japan Geriatrics Society.)

- Abstract
Risk perception is one of the core factors in theories of health behavior promotion. However, the association between knowledge, risk perception, and depressed mood in depression is unknown. The aim of this study was to clarify the relationships between subjective knowledge, risk perception, and objective scores of depression in community-dwelling elderly people in Japan. A total of 747 elderly participants (mean age: 76.1, female: 59.8%) who completed the 15-item Geriatric Depression Scale (GDS-15) along with items assessing subjective knowledge and risk perception were included in the analysis. We assessed the correlation between subjective knowledge and risk perception, and then compare GDS-15 scores by level of subjective knowledge and risk perception. Subjective knowledge was weakly associated with risk perception and related to lower GDS-15 scores in a dose-response pattern, which did not change after adjusting for age, gender, basic activities of daily living (ADL), instrumental ADL, years of education and history of depression. There was no significant association between risk perception and GDS-15 scores. The relationship between knowledge, risk perception, and depressed mood in younger generations is unclear, but warrants examination., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Background: The mothers of children with attention-deficit hyperactivity disorder tend to experience depression at higher levels because of the poor social interaction and deviant behaviors of their children. These depressed mothers often harm themselves and negatively impact their family and community., Purpose: This study examines maternal depression and its related factors in the mothers of school-aged children with attention-deficit hyperactivity disorder., Methods: A cross-sectional study with a purposive sampling of 100 mothers of school-age children with attention-deficit hyperactivity disorder was developed. Data were collected using a structured questionnaire that included the Parenting Stress Index (PSI), social support scale, and the Beck Depression Inventory (BDI). The Pearson product moment correlation and stepwise multiple regression were used to analyze data., Results: The findings showed that almost half of the mothers with school-aged ADHD children suffered higher pa-renting stress and that 34% required professional psychiatry referral. In addition, 40% of the participants suffered from depression. Higher levels of parenting stress were associated with a higher incidence of depression (r = .647, p < .001). Participants with better social support had lower depression levels (r = -.327, p < .01). 'Parenting stress' and having a monthly total household income of ≤ NT$40,000 were significant predictors of maternal depression. 'Maternal stress' was the most significant predictor, with a total explained variance of 41.9% (R(2) change = 41.9%)., Conclusions: The results of this study are intended to help medical staff better care for the mothers of school-aged children with ADHD. These results will assist in the evaluation of maternal depression, parenting stress, and levels of required social support. It will especially help in the evaluation of maternal depression symptoms of those mothers of low socioeconomic status with high parenting stress. Providing these mothers with parental training, education on effective parenting and discipline strategies, and better social support may effectively reduce maternal depression, which will help minimize the negative impacts of this depression on the family and the community.

- Abstract
This study sampled six times of river water, sediment, and tilapia (Oreochromis niloticus) in the Dan-Shui River, Taipei, Taiwan; 10 feminizing compounds were analyzed using ultra-performance liquid chromatography-tandem mass spectrometry. Bisphenol A (508 ± 634 ng/L, geometric mean (GM) 303 ng/L) and nonylphenol (491 ± 570 ng/L, GM 328 ng/L) were the most abundant among analytes in the river water. Nonylphenol (770 ± 602 ng/g wet weight, GM 617 ng/g wet weight) was also the highest in sediment. Fish may uptake nonylphenol and nonylphenol ethoxylates from river water and sediment because there were significant correlations between the concentrations in these matrixes and those in fish tissues (r s ranged from 0.21 to 0.49, p < 0.05). The bioaccumulation of nonylphenol, nonylphenol ethoxylates and bisphenol A in gonad, eggs, and liver was much higher than that in muscle (e.g. mean bioaccumulation factors of nonylphenol were 27,287, 20,971, 9,576 and 967, respectively) and might result in low liver fractions in fish body weights (0.66 % ± 0.39 %, GM 0.55 %) and the skewed sex ratio of fish (male to female = 0.52). This innovative study linked the environmental and internal doses statistically in the globally distributed wild fish by analyzing feminizing compounds in water, sediment, and four fish tissues including gonad and eggs.

- Abstract
We investigated the 15-item Geriatric Depression Scale (GDS-15) with regard to its factors and, reproducibility, as well as its relationship to activities of daily living, social factors, medical conditions, and quality of life for community-dwelling elderly people in Japan. The study population consisted of 736 community-dwelling elderly participants aged 65 or older. Exploratory factor analysis of the data and correlation coefficients between factors and activities of daily living, quality of life, social factors, and medical conditions were calculated for two consecutive years. The reproducibility of the results was also evaluated. As the result, GDS-15 had three reproducible factors specified as follows: factor I, "energy loss and pessimistic outlook"; factor II, "positive mental status (reversed)"; and factor III, "empty feeling." Comparing our findings with a review of research in this area, positive items (excluding "feel full of energy") seem to compose an universal factor. Factor I correlated best with quality of life, factor II with activities of daily living, and factor III with subjective cognitive function. These results suggest the GDS-15 can be used to assess the functional ability and quality of life, as well as depressive mood in older adults., (Copyright © 2013 Elsevier Ireland Ltd.

- Abstract
We used logotherapy concepts to manage the mental impact of recurrent cancer on a patient. The patient had received radiotherapy for nasopharyngeal carcinoma approximately one year prior to the March 9th - April 21st, 2011 nursing care period. The authors interacted with the patient during the care period via personal observation and telephone interview. Patient data was also collected from medical staff. Integral nursing assessment disclosed that the patient faced several major nursing issues, including death anxiety, pain, and sleep disturbance. This report describes how logotherapy was utilized to enable the patient better understand his condition and ultimately allow him to identify and pursue renewed meaning and happiness in life. Logotherapy helped alleviate the death anxiety caused by recurrent cancer and helped the patient self-reconfirm the meaning of life.

- Abstract
Objective: To compare the effects of intra-articular hyaluronic acid (HA; ARTZ) and transcutaneous electric nerve stimulation (TENS) in the treatment of patients with knee osteoarthritis., Design: A prospective, randomized controlled trial., Setting: Rehabilitation clinic of a teaching hospital., Participants: Patients with knee osteoarthritis (N=50; aged 51-80y) were randomly assigned to the HA group (n=27) or the TENS group (n=23)., Interventions: The HA group received intra-articular HA injection into the affected knee once a week for 5 consecutive weeks, and the TENS group received a 20- minute session of TENS 3 times a week for 4 consecutive weeks., Main Outcome Measures: The primary outcome measures used were the visual analog scale (VAS) for pain and the Lequesne index. The secondary outcome measures were range of motion of the knee, walking time, pain threshold, patient global assessment, and disability in activities of daily living. All subjects were assessed at baseline, and at 2 weeks, 2 months, and 3 months after the treatments were completed., Results: The TENS group exhibited a significantly greater improvement in VAS than the HA group at 2 weeks' follow-up (4.17 ± 1.98 vs 5.31 ± 1.78, respectively; P=.03). In addition, the TENS group also exhibited a significantly greater improvement in the Lequesne index than the HA group at 2 weeks' follow-up (7.78 ± 2.08 vs 9.85 ± 3.54, respectively; P=.01) and at 3 months' follow-up (7.07 ± 2.85 vs 9.24 ± 4.04, respectively; P=.03)., Conclusions: TENS with silver spike point electrodes was observed to be more effective than intra-articular HA injection for patients with knee osteoarthritis in improving the VAS for pain at 2 weeks' follow-up as well as the Lequesne index at 2 weeks' and 3 months' follow-up., (Copyright © 2013 American Congress of Rehabilitation Medicine.

- Abstract
This study developed and validated a method of measuring the feminizing chemicals 4-tert-octylphenol, 4-nonylphenol, nonylphenol monoethoxycarboxylate (NP(1)EC), nonylphenol monoethoxylate (NP(1)EO), nonylphenol diethoxylate (NP(2)EO), estrone, 17β-estradiol, estriol, 17α-ethinyl estradiol and bisphenol A in river water, sediment, and tissue using ultra-high performance liquid chromatography/tandem mass spectrometry (UHPLC/MS/MS) and isotope-dilution techniques. Water samples were pretreated using disk-type automated solid-phase extraction (SPE). Solid samples of sediment, fish, and clams were treated with matrix solid-phase dispersion (MSPD) using C(8) adsorbent. Eluents were directly passed following alumina cartridges for cleanup. The signal intensity of analytes on electrospray ionization (ESI) was compared with that of atmospheric pressure photoionization (APPI). The analytes were separated on a UHPLC C(18) column with aqueous 10-mM ammonium acetate for NPEOs and aqueous 10-mM N-methylmorpholine for the other compounds. On-line cleanup was evaluated using two-dimensional liquid chromatography (2-D LC). ESI could provide satisfactory response for all of the analytes. Though APPI did not offer suitable response for NP(1)EO, NP(2)EO and NP(1)EC, it provided better signal intensities for the steroid estrogens (1.0-2.4 times) and the phenols (3.2-4.4 times) than ESI. UHPLC shortened chromatographic time to less than 10 min. Disk-type automated SPE and MSPD dramatically increased the throughput of sample preparation. The extraction efficiency on surface water samples ranged from 10% to 91%. The extraction efficiency of MSPD on sediment, fish, and clams was 51-101%, 36-109%, and 30-111%, respectively. Acidic alumina cleanup was essential for the analysis of the tissue sample, and reduced matrix effects better than 2-D LC on-line cleanup. The limits of detection (LODs) in water ranged from 0.81 ng/L to 89.9 ng/L. The LODs in sediment and tissue ranged from tens of pg/g wet weight to only a few ng/g wet weight. This method proved to be accurate and reproducible, as both quantitative biases and relative deviations remained smaller than 20% at three spiked levels., (Copyright © 2011 Elsevier B.V.

- Abstract
A sensitive method was developed using ultra-high-performance liquid chromatography (UHPLC)/MS/MS with positive electrospray ionization for determining aflatoxin M1 (AFM1) in milk and milk powder. A 50 mL quantity of low-fat liquid milk containing 100 ng/L AFM1, was prepared using immunoaffinity columns with a mean recovery rate of 79% (n = 3). UHPLC columns (BEH C18, BEH HILIC, and HSS T3) greatly reduced the chromatographic time and lowered the instrumental detection limits (IDLs) 16 to 58 times compared to an HPLC column (Betabasic C18). The HSS T3 column was chosen because it provided a low IDL (0.11 pg) and the lowest ion suppression of signal intensity (63.4%) among the tested columns. Matrix-fortified calibration curves were used for quantification and showed good linearity (r > 0.997) at 0.05-500 ng/mL. The LOD was 0.18 ng/kg for milk and 2.08 nglkg for milk powder, based on the signal intensity of the confirmatory product ion (m/z 259.1), which was less abundant than the quantitative product ion (m/z 273.1). Certified reference materials of milk powder at three levels (<0.05, 0.111 +/- 0.018, and 0.44 +/- 0.06 microg/kg) were measured within a day and between days; the results were all close to the certified levels with low variations (RSDs < 15%), showing good precision and accuracy.

- Abstract
Objectives: To explore the risks and rates of readmission and their predictors 14 days, one year, and five years after discharge for the psychiatric population in Taiwan., Methods: This was a prospective study based on claims from 44,237 first-time hospitalized psychiatric patients discharged in 2000, who were followed for up to five years after discharge. The cumulative incidence and incidence density of readmission were calculated for various follow-up periods after discharge, and Cox proportional hazard models were generated to identify the significant predictors for psychiatric readmission., Results: The less than 14-day, one-year, and five-year cumulative incidences were estimated at 6.1%, 22.3%, and 37.8%, respectively. The corresponding figures for incidence density were 4.58, 1.04, and 0.69 per 1,000 person-days, respectively. Certain factors were significantly associated with increased risk of readmission irrespective of the length of follow-up, including male gender, length of hospital stay >15 days, economic poverty, a leading discharge diagnosis of schizophrenia/affective disorders, and residence in less-urbanized regions. Compared to children/adolescents, young adults (20-39 years) were significantly associated with increased risks of

- Abstract
This article reports on the experience of clinical nurses in treating a patient with bipolar disorder who was re-hospitalized following a relapse attributed to poor medical alliance. During the period of nursing care (February 2 to April 7 2009), observation and interviews employed to assess the patient resulted in the three nursing diagnoses of violence risk, disorganized thinking process, and poor medical alliance. With the goal of enhancing medical alliance, an individualized plan of nursing care designed to better understanding the patient's illness history, illness and treatment attitudes, and feelings of ambivalence towards medicines was implemented in order to foster a closer nurse-patient relationship and enhance patient motivation to accept medical treatment to permit a return to a normal life as soon as possible.

- Abstract
Autophagy is a catabolic process by which cells remove long-lived proteins and damaged organelles for recycling. Viral infections may also induce autophagic response. Here we show that hepatitis B virus (HBV), a pathogen that chronically infects approximately 350 million people globally, can enhance autophagic response in cell cultures, mouse liver, and during natural infection. This enhancement of the autophagic response is not coupled by an increase of autophagic protein degradation and is dependent on the viral X protein, which binds to and enhances the enzymatic activity of phosphatidylinositol 3-kinase class III, an enzyme critical for the initiation of autophagy. Further analysis indicates that autophagy enhances HBV DNA replication, with minimal involvement of late autophagic vacuoles in this process. Our studies thus demonstrate that a DNA virus can use autophagy to enhance its own replication and indicate the possibility of targeting the autophagic pathway for the treatment of HBV patients.
