Impact of administrative state capacity determinants on sustainable healthcare.

Public administration implements government policies through prudent administrative practices and state capacity. Based on Asia's political and administrative proficiency and paradox, this study explores the administrative state capacity determinants-bureaucratic quality (BQ) and military in politics (MP)-and their interaction with sustainable public health quality (PHQ) in Asia from 2006 to 2020. With its focus on the scenario and Asian state administrative issues, Goal 04: Health and Well-being of Sustainable Development Goals has been the core aspect of state capacity and sustainable development. Applying the generalized method of moments (GMM) econometric estimation, the study finds that the high risk of poor BQ due to political pressures and policy inconsistency has significantly and negatively impacted PHQ in Asia. In contrast, by overtaking the administration, a high degree of MP and military dominancy has been a progressive force for PHQ in Asia. The interaction of BQ and MP negatively affects the state's social development due to conflict of interest and shredding policy outcomes. This is the first study that deals with the nexus between sustainable development and administrative state capacity determinants of Asia's public sector. The paper finds that an effective and prudent administrative collaboration and expertise-sharing between the bureaucracy and the military accelerates sustainable healthcare in Asia. Furthermore, the study believes that a healthy institutional collaboration will help overcome the development loopholes in Asia, promote PHQ, and accelerate regional development.

CS-NO suppresses inhibits glycolysis and gastric cancer progression through regulating YAP/TAZ signaling pathway.

CONTEXT: Gastric cancer (GC) is a significant contributor to global mortality and is recognized for its elevated prevalence and fatality rates. Nitric Oxide (NO) plays a role in multiple aspects of cancer metastasis and progression. CS-NO is a polysaccharide-based biomaterial with NO-releasing properties that shows promising therapeutic potential. Nonetheless, the action mechanism of CS-NO in GC is still largely unclear. METHODS: The present study employed various experimental techniques, including CCK-8 assay, colony formation assay, EdU staining, and transwell assays, to evaluate the proliferation, migration, and invasion of GC cells. Additionally, ELISA was utilized to measure glucose uptake, lactate production, and cellular ATP levels in GC cells. In vivo investigations on nude mice were conducted to validate the in vitro results. OBJECTIVE: The present study aimed to examine the potential anti-tumor properties of CS-NO on GC through in vitro and in vivo investigations, while also exploring the underlying mechanisms involved. RESULTS: Our data suggested that CS-NO might prevent GC cell invasion and migration. Decreased expressions of GLUT1, HK2, and LDHA further demonstrated that CS-NO significantly suppressed aerobic glycolysis in GC cells. The administration of CS-NO resulted in a significant reduction of YAP and TAZ levels in GC cells. Our data further show that CS-NO treatment could inhibit GC cancer growth in mice, consistent with the significant decrease in Ki67, GLUT1 and YAP expression levels. DISCUSSION AND CONCLUSION: These findings could reveal the good effects of CS-NO therapy on inhibiting GC.

Methodological Study on the Establishment of HLA/HPA Gene Bank of Platelet Donors and Its Clinical Application.

The current study aimed at establishing a large-scale platelet donor database with known HPA and HLA genotypes in Ningbo, to provide matched platelets for the clinic and prevent the occurrence of ineffective immune platelet transfusion refractoriness (PTR). The platelet banks of clinical donor wtih HLA-A, HLA-B, HPA1, HPA2, HPA3, HPA4, HPA5, HPA6, HPA10, HPA15 and HPA21 genotyps were established. Meanwile, the platelet gene matching was performed on the donor. It was found that there were phenotype polymorphisms in 1000 donnors with HPA1, HPA2, HPA3, HPA4, HPA5, HPA6, HPA10, HPA15 and HPA21 genotyps, and allel polymorphism distribution in donnors with HPA1, HPA2, HPA3, HPA4, HPA5, HPA6, HPA15, HPA21 genotyps. The frequency of HPA10 was a gene, and not b gene, showing a single linear distribution. The HPA 2, HPA3, HPA15 system were the most polymorphic with three phenotypes: aa, ab, bb. In the HLA-A allele, the highest frequency is A*11:01 (24.25%). There were 13 alleles that were greater than 1%, such as A*24:02, A*02:01, A*33:03, and the accumulated frequency reached 96.20%. In the HLA-B allele, the highest gene frequency was B*40:01 (13.40%). There were 24 alleles that were greater than 1%, such as B*46: 01, B*58: 01, B*15: 01, and the accumulated frequency reached 91.60%. Platelet antibody cross matching was performed on 100 blood samples from patients with thrombocytopenia after multiple platelet transfusions. The number of consistent samples was 46 (46%). Twenty patients were transfused with platelet cross matching. Among them, 18 patients had obvious improvement in clinical symptoms and good hemostatic effect after transfusion, which was judged to be effective. Platelet donor HPA and HLA-A, B antigen genotyping database provided patients with individual appropriate platelets, and provided the effectiveness of immune platelet infusion ensuring effective platelet transfusion.

COVID-19 pandemic, government response, and policy implications in China, India, Iran, and Pakistan (CIIP).

COVID-19 has been considered as a catastrophic global health response mechanism and demonstrated the international preparedness for the outbreak as well as government initiatives. This study aims to evaluate the comparative analysis of government response in China, India, Iran, and Pakistan (CIIP) countries regarding their policy enforcement on combating COVID-19 by using stringency, socioeconomic, and health containment indices. The proposed study analyzed the policy implications in CIIP from January 1, 2020 through July 21, 2020. Data have been collected from the European Union, World Health Organization, Humanitarian Exchange, and a selected National Database. Results show that despite a high degree of government's strict policies in India and Pakistan, they have been failing to control the brutality of the COVID-19. In contrast, the politics of China and Iran appear to be very successful in combating the situation in COVID-19. This study concludes that countries with ample resources and stronger coping strategies should provide developing countries with the mean for mitigating and improve their socioeconomic and economic crises, which hindered their consistent policy enforcement during the COVID-19 pandemic.

Acupuncture Combined with Three-Step Analgesic Drug Therapy for Treatment of Cancer Pain: A Systematic Review and Meta-Analysis of Randomised Clinical Trials.

OBJECTIVE: The purpose of this study was to systematically evaluate the efficacy and safety of acupuncture combined with the WHO three-step analgesic drug ladder for cancer pain. METHODS: The Cochrane Library, PubMed, and CNKI Database of Systematic Reviews were searched. Using the Cochrane Register for Randomized Controlled Trials, the quality of the included literature was evaluated, and the meta-analysis was carried out with RevMan 5.3 software. RESULTS: Compared with three-step analgesia alone, acupuncture combined with three-step analgesia for cancer pain increased pain relief response rates (RR = 1.12, 95% CI: 1.08∼1.17, P < 0.00001), reduced NRS score (SMD = -1.10, 95% CI: -1.86∼-0.35, P=0.004), reduced the rate of side effects (RR = 0.45, 95% CI: 0.38∼0.53, P < 0.00001), including nausea (P < 0.00001), vomiting (P=0.008), constipation (P < 0.00001), and dizziness (P=0.010), reduced the burst pain rate (SMD = -1.38; 95% CI: -2.44∼-0.32, P=0.01), shortened analgesia effect onset time (P=0.004), and extended the duration of response (P < 0.0001). CONCLUSION: For the treatment of cancer pain, acupuncture combined with three-step analgesic drugs is better than using only three-step analgesic drugs.

Role of foreign direct investment interaction to energy consumption and institutional governance in sustainable GHG emission reduction.

The theme of the environmental upgrades and Sustainable Development Goals (SDGs) of the United Nations is "Better Environment, Better tomorrow." This study uses regulatory quality (RgQ) and energy consumption per capita (EC) as explanatory variables and foreign direct investment (FDI) as an integrating variable with RgQ and EC and examines their impacts on greenhouse gas (GHG) emissions from 2001 to 2018 in panel Asian economies. The findings indicate that EC negatively impacts GHG emissions, while RgQ positively promotes the reduction of GHG emissions in Asia. In addition, FDI has an integrating role, as sufficient FDI inflows significantly enhance clean energy use and EC efficiency. Such inflows also support and improve Asia's regulation quality by upgrading standardization investments and technology deployment to enhance institutional quality and achieve SDGs. FDI inflows have thus been vital in environment upgrading in Asia and regional sustainable environmental development.

Impact of COVID-19 pandemic on sustainability determinants: A global trend.

For the last six months till today, the world had had no luck in defeating COVID-19. This study examined the impact of the COVID-19 Pandemic on sustainability determinants, with the time arisen from December 27, 2019, through June 30, 2020. This study considers quantitative COVID-19 dashboard data with sustainable determinants; old age group, people exposed to air pollution, and countries with the most international travelers. Applying linear regression examines that COVID-19 behavior concerning the aging population and countries host the most international travelers, more positively significant than people exposed to PM2.5% air pollution, respectively. This study made a novel contribution by analyzing two variables' interaction; first, the aging population and the countries that host the most international travelers. Secondly, the aging population and people exposed to air pollution are vulnerable to COVID-19 globally, a novel concept comprehensively. Results show that countries with aging populations are more exposed to COVID-19, and its interaction term host the most international travelers. It also analyses that the aging population and its interaction with people exposed to air pollution are also vulnerable to COVID-19 but marginally lesser than the former. However, their behavior varies from country to country, making room for future study to analyze a more in-depth analysis. It gives a different dimension to consider other risk factors of COVID-19 by bearing in mind its unique contagious characteristics, which will help policymakers draft a sound epidemic preparedness policy to tackle the unforeseen crisis. It gives a thought of provoking to policy practitioners for the risk characteristics of COVID-19, which needs a reassessment to epidemic risk management to deal with this, and future unforeseen crisis by considering Sustainable Development Goals.

These measures have remained sustainable and consistent, which made China resumption the economy and state development affairs. Furthermore, the second wave of COVID-19 was also under control due to sustainable policy enforcement during the first wave. In strengthening the health system and e-government system, China's 6G successful invention will make china's institutional structure to the next level and sustainable in combating future calamities and projected forthcoming waves of COVID-19.

Based on BATMAN-TCM to Explore the Molecular Mechanism of Xihuang Pill Regulating Immune Function to Treat Breast Precancerous Lesions.

OBJECTIVE: The specific mechanism of Xihuang Pill in the treatment of breast precancerous lesions and breast cancer has not yet been elucidated. METHODS: In our study, BATMAN-TCM (a Bioinformatics Analysis Tool for Molecular mechanisms of Traditional Chinese Medicine) was used to forecast the relationship among chemical components, immune targets, and diseases of each herb in Xihuang Pill and constructed a component-target-disease network. Taking breast precancerous lesion model rats as the research object, the molecular mechanism of Xihuang Pill regulating immunity was analyzed. RESULTS: BATMAN-TCM prediction showed that 309 genes were enriched in the biological process of "immune system response", which was the target of Xihuang Pill to regulate the immune system. The target of breast cancer disease and the genes related to Xihuang Pill's immune system response were crossed, and 88 cross genes were obtained. According to the enrichment results of GO/KEGG pathway, T cell activation was found to be the most relevant. We select Th1 cells (IL-2, IFN-γ) and Th2 cells (IL-4, IL-10) among them for animal experiment verification. The results show that Xihuang Pill can upregulate the serum IFN-γ and IL-2 levels, reduce the IL-4 and IL-10 levels, and regulate the balance of Th1/Th2 cells in the peripheral blood of rats with breast precancerous lesions. CONCLUSION: Xihuang Pill targets a variety of immune-related molecules related to breast precancerous lesions and is a traditional Chinese medicine formula that effectively regulates immune function.

Detection and Fitness of Dicarboximide-Resistant Isolates of Alternaria alternata from Dendrobium officinale, a Chinese Indigenous Medicinal Herb.

Black spot, caused by Alternaria alternata, poses a severe threat to the industry of Dendrobium officinale, a Chinese indigenous medicinal herb. Dicarboximide fungicides (DCFs) have been intensively used to control this disease for decades in China, and offer excellent efficacy. The resistance of phytopathogenic pathogens against DCFs are reportedly selected in fields; however, the DCF resistance of A. alternata from D. officinale is not well understood. The isolates of A. alternata with low procymidone resistance (ProLR) were detected in the commercial orchards of D. officinale in China in 2018 and biochemically characterized in this study. The result showed that the ProLR isolates were selected in the commercial orchards with a resistance frequency of 100%, and no significant difference in mycelial growth, sporulation, and virulence was observed among the ProLR and procymidone-sensitive (ProS) isolates. A positive cross-resistance pattern was exhibited between procymidone and iprodione. Results of amino acid sequence alignment of AaOS-1 from the tested isolates showed that all of the ProLR genotypes could be categorized into two groups, including group I (mutations at AaOs-1) and group II (no mutation). Under procymidone (5.0 µg/ml) treatment conditions, the AaOs-1 expression levels increased in the ProS isolates and ranged from approximately 2.94- to 3.69-fold higher than those under procymidone-free conditions, while the AaOs-1 expressions of the ProLR isolates were significantly lower than those in the ProS isolates under the same conditions. The data indicated that the mutations at AaOs-1 are involved in the DCF resistance of A. alternata selected in the D. officinale orchards.

Detection and Biological Characteristics of Alternaria alternata Resistant to Difenoconazole from Paris polyphylla var. chinensis, an Indigenous Medicinal Herb.

Black spot caused by Alternaria alternata (BSAA) is one of the most common diseases of Paris polyphylla var. chinensis, causing yield losses in China. Demethylation inhibitors (DMIs) have been used to control this disease in China for decades. Some farmers have complained about the decreased efficacy of DMIs against BSAA. The objective of this study was to detect and characterize the resistance of A. alternata against difenoconazole from P. polyphylla var. chinensis during 2018. Of the 22 isolates of A. alternata obtained from Sichuan Province in the southwest of China, 20 were resistant to difenoconazole. Mycelial growth rates and sporulation of the difenoconazole-resistant (DfnR) isolates were not different from those of the difenoconazole-sensitive (DfnS) isolates. No cross resistance between difenoconazole and tebuconazole or propiconazole was observed. Mutations were identified at gene AaCYP51 of DfnR isolates based on the sequence alignment of the DfnR and DfnS isolates. All of the mutations could be divided into three resistant genotypes, I (K715R + Y781C), II (K715R + D1140G + T1628A), and III (no mutation). The docking total score of the DfnS isolates was 5.6020, higher than the resistant genotype I (4.4599) or the resistant genotype II (3.8651), suggesting that the DMI resistance of A. alternata may be caused by the decreased affinity between AaCYP51 and difenoconazole.

A Network Pharmacology-Based Identification Study on the Mechanism of Xiao-Xu-Ming Decoction for Cerebral Ischemic Stroke.

OBJECTIVE: We used the network pharmacological analysis method to explore the mechanism of multicomponent, multitarget, and multiway actions of Xiao-Xu-Ming decoction (XXMD) for cerebral ischemic stroke (CIS), which provided a basis on the research of innovative drugs. METHOD: We used the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) to retrieve the active ingredients and targets of 12 herbs of XXMD; we used the Gene Expression Omnibus (GEO) database of the National Center for Biotechnology Information (NCBI) to screen for differentially expressed genes in CIS to obtain the disease targets of CIS and to intersect it with the action targets of XXMD, and then the target drug efficacy is obtained. We used Cytoscape 3.6 software to construct the drug-active ingredient-action target interaction network of XXMD to treat CIS and conduct protein-protein interaction (PPI) network and topology analysis. The action target Gene Ontology (GO) biological processes and metabolic pathways in Kyoto Encyclopedia of Genes and Genomes (KEGG) of XXMD to treat CIS were enrichment analyzed with R software. RESULT: We screened out 226 active ingredients and 3646 action targets for XXMD. Among them, XXMD to treat CIS has 144 active ingredients, 12 targets, and proteins in the core network of PPI having STAT3, HIF1A, etc. Pathway enrichment analysis was based on the GO and KEGG biological processes involved in active oxygen metabolism, smooth muscle cell proliferation, cytokine production, angiogenesis, redox coenzyme metabolism, and oxidative stress. The main action processes are significantly associated with CIS signal pathways involved in microRNAs, ovarian steroid hormones, NF-кB signaling pathway, Th17 cell differentiation pathway, HIF-1 signaling pathway, folic acid synthesis pathway, galactose metabolism, and fructose and mannose metabolism. CONCLUSION: This study initially clarified the main targets and pathways of XXMD in the treatment of CIS, which can lay the foundation for further research on its pharmacological effects.

Hepatopoietin Cn (HPPCn) Generates Protective Effects on Acute Liver Injury.

Objective: To observe the protective role of hapatopoietin Cn (HPPcn) on acute liver injury. Methods: Six hours after 10 mmol/L CCl4, 150 mmol/L ethanol, or 0.6 mmol/L H2O2 treatment, SMMC7721 human hepatoma cells were incubated with 10, 100, or 200 ng/ml recombinant human HPPCn protein (rhHPPCn) for an additional 24 h. The cell survival rate was analyzed using the CCK-8 assay. The CCl4-induced apoptosis of SMMC7721 cells was detected by flow cytometry. Then, the levels of glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), malondialdehyde (MDA), lactate dehydrogenase (LDH), glutathione peroxidase (GSH-PX), and superoxide dismutase (SOD) in SMMC7721 cell lysates and cell culture supernatant were detected. SMMC7721 cells were treated with different concentrations of rhHPPCn (0, 10, and 100 ng/ml). The cell proliferation indexes (BrdU incorporation and PCNA expression) were detected by immunohistochemistry (IHC). An acute liver injury mouse model was established by a one-time intraperitoneal injection of 20% CCl4 at a volume of 5 ml/kg body weight. One hour after CCl4 injection, 1.25 or 2.5 mg rhHPPCn/12 h/kg body weight was injected via the tail vein. The serum levels of GOT and GPT were detected at different time points. Pathological changes in the liver were evaluated. PCNA expression levels were observed by IHC. Results: rhHPPCn increased the survival rate of SMMC7721 cells and inhibited chemical toxicity-induced cell apoptosis. The levels of GOT, GPT, MDA, and LDH in the cell supernatant were significantly reduced, while GSH-PX and SOD were significantly increased after rhHPPCn treatment in the CCl4-treated SMMC7721 cells. BrdU incorporation and PCNA expression increased in a concentration-dependent manner, indicating that rhHPPCn promotes cell proliferation. The results showed that rhHPPCn significantly reduced the serum levels of GOT and GPT in CCl4-induced acute liver injury mice. rhHPPCn alleviated the tissue damage and increased PCNA expression, indicating the promotion of proliferation after acute injury. Conclusion: rhHPPCn protects hepatocytes from chemical toxins by promoting proliferation and inhibiting apoptosis in vivo and in vitro. Our study provides new insights for the clinical treatment of acute liver injury.

Thoracoscopic Repair by Simplified Mattress Sutures for Diaphragmatic Hernia in the Neonate When No Posterolateral Diaphragmatic Rim Exists.

Purpose: The aim of this retrospective study is to describe our initial experience by using new simplified mattress sutures with syringe needle for congenital diaphragmatic hernia (CDH) in neonates when no posterolateral rim of diaphragm exists. Methods: A retrospective review of the new simplified technique in 15 cases from February 2015 to February 2018 at a single institution was performed. In the procedure, two to three primary suture sites were taken from the relative intercostal region of the body surface. Two 2-0 nonabsorbable sutures around the rib were inserted between the anterior rim of the defect and the relative rib through a syringe needle. Knot tying was made extracorporally and the knots were under the skin of intercostals space. Results: Among the patients, 9 were male and 6 were female. The age was 10 minutes-1 day when admitted, 10 were term newborns, and 5 were premature. The mean operative time was 37.5 minutes (range, 25-60 minutes) for each CDH repair. No cases required conversion to open surgery, blood loss was minimal. The mean follow-up duration was 18.5 months (range 3-27 months), with no deaths, and no single case of recurrence. Conclusion: We have found this simple technique to be a useful adjunct in the thoracoscopic management of selected cases with CDH. It has the advantages of reduced operative time, simplicity, and feasibility and has the value of clinical popularization.

Laparoscopic Ileocolic Pexy as Preventive Treatment Alternative for Ileocolic Intussusception With Multiple Recurrences in Children.

PURPOSE: Idiopathic intussusception is one of the most common causes of small bowel obstruction in children. To decrease subsequent recurrence and to detect a lead point, an early laparoscopy was performed for children with multiple recurrent ileocolic intussusception. MATERIALS AND METHODS: Between January 2014 and July 2017, a total of 2561 consecutive children with intussusception were treated and followed. There were 110 patients with multiple recurrences, 61 were treated with ileocolic pexy and 49 were not and the results were compared. Using a 5-mm laparoscope and 2 additional transabdominal wall stab incisions, an appendectomy and an ileocolic pexy with nonabsorbable sutures were performed simultaneously for the children after the last successful enema reduction. RESULTS: The mean operative time was 59.4±13.1 minutes (range, 45 to 85 min). No cases required conversion to an open surgery, blood loss was minimal. There was no operative morbidity. Two patients were found with a Meckel's diverticulum, and were removed by slightly enlarged transumbilical incision. The 61 cases were followed up for 4 to 42 months (mean, 19.3±1.1 mo). In the ileocolic pexy group, 2 of 61 (3.2%) got 2 episodes of recurrences. Among the 25 patients with 3 recurrences without undergoing ileocolic pexy, 18 (72%) had 22 episodes of recurrence. Of the 16 patients with 4 recurrences and without ileocolic pexy, 14 (87.5%) had 17 episodes of recurrence. There was statistical difference in recurrent rate among the 3 groups (ileocolonic pexy group vs. 3 recurrences group, P<0.01; ileocolic pexy group vs. 4 recurrences group, P<0.01). CONCLUSIONS: Early preventive laparoscopic ileocolic pexy should be undertaken for the patients with multiple recurrences after the last nonsurgical reduction had been attempted successfully.

Resveratrol inhibits proliferation, promotes differentiation and melanogenesis in HT-144 melanoma cells through inhibition of MEK/ERK kinase pathway.

The present study was aimed to investigate the effect of resveratrol on the viability of HT-144 melanoma cells and formation of melanin. MTT assay was used for analysis of cell viability and western blot for determination of phospho-Mek 1/2, phospho-Erk 1/2 (Tyr-204), Mitf, PBG-D and p-CREB-1 expression. MTT assay results showed that treatment of HT-144 cells with various doses of resveratrol led to a concentration dependent inhibition of proliferation. The antiproliferative activity was significant at 15 µM concentration of resveratrol after 24 h. Western blot analysis revealed that resveratrol caused significant reduction in the expression of phospho-extracellular signal related kinase (p-ERK) and p-MEK 1/2. Additionally, tyrosinase activity was increased by 1.5-6.8-fold on increasing the concentration of resveratrol from 1 to 15 µM. Resveratrol treatment also enhanced the expression of cAMP-response element-binding proteins (CREB) after 24 h. Furthermore resveratrol treatment up-regulated porphobilinogen deaminase (PBG-D) expression in HT-144 cells. Taken together, the study demonstrates that resveratrol treatment inhibits proliferation and promotes melanogenesis of HT-144 cells through inhibition of MEK/ERK pathway. Therefore, resveratrol has a scope for further evaluation against melanogenesis.

Role of clinical nursing path combined with traditional Chinese dialectical nursing in the treatment of knee osteoarthritis.

OBJECTIVE: To investigate the effect of clinical nursing path in combination with Chinese dialectical nursing on patients with knee osteoarthritis. METHODS: Randomized controlled trial of 60 patients with knee osteoarthritis in our hospital between 2012 and 2013 was enrolled. The control group received only routine care by using traditional model, while the experimental group was subjected to routine care with additional Chinese dialectical nursing. RESULTS: No significant difference in WOMAC scores in the two groups after admission (P>0.05). The WOMAC scores were significantly improved in the experimental group 3 weeks after admission (P<0.05). The mastery of disease and self health care knowledge, compliance with the doctor, nursing satisfaction index and the standard rate of health education in intervention group are obviously better than the control group, the difference was statistically significant (P<0.05). Following-up study indicates that the WOMAC scores and readmission rate was significantly decreased in the intervention group (P<0.05). CONCLUSION: Combination of clinical nursing path with Chinese dialectical nursing can significantly improve the clinical presentation, self-care consciousness and the clinical nursing satisfaction, and it is worthy of clinical application.
