RESUMEN
BACKGROUND: Changes to the wound dressing frequently cause pain. Some adverse side effects of pharmacologic pain management may cause problems or even impede wound healing. There is no systematic study of non-pharmacologic therapies for pain during wound dressing changes, despite the gradual promotion of non-pharmacologic pain reduction methods. OBJECTIVES: To give clinical wound pain management a new direction, locating and assessing non-pharmacological interventions regarding pain brought on by wound dressing changes are necessary. METHOD: The researchers conducted a comprehensive literature review on non-pharmacological interventions for pain during wound dressing changes across five databases: PubMed, Web of Science, Medline, Embase, and the Cochrane Library spanning the period from January 2010 to September 2022. The evaluation of literature and data extraction was carried out independently by two researchers, and in cases of disagreement, a third researcher participated in the deliberation. To assess the risk of bias in the literature, the researchers utilised the Cochrane Handbook for Reviews of Interventions, version 5.1.0. RESULTS: In total, 951 people were involved in 11 investigations covering seven non-pharmacological therapies. For pain triggered by dressing changes, virtual reality (VR) distraction, auditory and visual distractions, foot reflexology, religious and spiritual care, and guided imaging demonstrated partially positive effects, with hypnosis therapy and jaw relaxation perhaps having a weak effect. CONCLUSION: The key to managing wounds is pain management. According to our review, there is some indication that non-pharmacologic interventions can help patients feel less discomfort when having their wound dressings changed. However, the evidence supporting this view is weak. It needs to be corroborated by future research studies with multicentre and large samples. To promote and use various non-pharmacologic interventions in the future, it is also necessary to build standardised and homogenised paths for their implementation.

Objective: To investigate the preference of elderly patients for "Internet + Nursing Service", so as to provide reference for accurately matching their service needs. Methods: Based on discrete choice experiments, the elderly patients' "Internet + Nursing Service" choice preference questionnaire was prepared, and 410 elderly patients were interviewed face-to-face. The Conditional Logit Model was used for quantitative analysis of the experimental data. Results: The six attributes included in the study had a significant impact on the elderly patients' preference for "Internet + Nursing Service" (P < .05). Among non-economic attributes, "medical insurance reimbursement ratio -70%" has the highest utility (.263, P < .001), with "hospital size - larger (.205, P < .05)" and "medical insurance reimbursement ratio -50%" (.188, P < .05) ranking second and third, respectively. The relative importance of the attribute of medical insurance reimbursement proportion is the highest (26.44%), and the relative importance of service content is the lowest (9.78%). If the proportion of medical insurance reimbursement increases from 30% to 70%, patients are willing to pay 202.9 yuan, and the probability of choosing "Internet + Nursing Service" increases by 6.1%. Conclusion: Patients prefer to choose a higher proportion of medical insurance reimbursement, a larger medical institution, a higher level of nurses, low single service costs, a basic package, and "Internet + Nursing Service" led by the government and hospitals. Improvement of the price and medical insurance payment policy is recommended, along with the enhancement of the ability of primary nursing services, strengthening of the management of Internet enterprise platforms, and scientific assessment of the needs of patients for personalized nursing services.
RESUMEN
Objective: Symptom Management Theory has been extensively used in guiding clinical practice to reduce patients' symptom burden, improve their outcomes and quality of life. However, concerning various participants, settings and methods, the effectiveness of practice and research based on the theory was inconsistent, which hindered the further implementation of this theory in clinical practice. Thus, this study aims to systematically evaluate the effectiveness of the Symptom Management Theory in guiding clinical practice. Methods: Systematic review. An online search of Chinese and English databases, including SinoMed, CNKI, WanFang Library, VIP database, MEDLINE, PubMed, Embase, Web of Science database, and Cochrane Library up to December 2023. This systematic review was conducted in accordance with the Joanna Briggs Institute critical appraisal checklist for randomized controlled trials and controlled clinical trials. The literature appraisal and extraction were independently conducted by two researchers. The third person was consulted if there was any disagreement between the two researchers. Results: A total of 20 articles (15 randomized controlled trials and five controlled clinical trials) were finally included. The overall quality of the articles was high. Additionally, the results showed that symptom management measurements based on the Symptom Management Theory could reduce the severity of patient's symptoms, alleviate their distress, relieve patients' anxiety and depression and improve their quality of sleep and quality of life. Conclusion: The Symptom Management Theory positively influenced clinical symptom management. It could provide theory-based symptom management methods in clinical practice to reduce patients' severity and burden of symptoms, level of anxiety, depression and distress. More high-quality original research should be conducted to further explore the theory's influence in guiding clinical practice in the future.
RESUMEN
OBJECTIVE: To explore the anti-tumor effect of safflower yellow (SY) against hepatocellular carcinoma (HCC) and the underlying potential mechanism. METHODS: An in vitro model was established by mixing Luc-Hepa1-6 cells and CD3+CD8+ T cells, followed by adding programmed cell death protein 1 (PD-1) antibody (Anti-mPD-1) with or without SY. The apoptosis was detected by flow cytometry and the level of inflammatory cytokines was determined by enzyme-linked immunosorbent assay. The protein levels of programmed cell death 1 ligand 1 (PD-L1), chemokine ligand (CCL5), C-X-C motif chemokine ligand 10 (CXCL10) were measured by Western blot. An in situ animal model was established in mice followed by treatment with anti-mPD-1 with or without SY. Bioluminescence imaging was monitored with an AniView 100 imaging system. To establish the FAK-overexpressed Luc-Hepa1-6 cells, cells were transfected with adenovirus containing pcDNA3.1-FAK for 48 h. RESULTS: The fluorescence intensity, apoptotic rate, release of inflammatory cytokines, and CCL5/CXCL10 secretion were dramatically facilitated by anti-mPD-1 (P<0.01), accompanied by an inactivation of PD-1/PD-L1 axis, which were extremely further enhanced by SY (P<0.05 or P<0.01). Increased fluorescence intensity, elevated percentage of CD3+CD8+ T cells, facilitated release of inflammatory cytokines, inactivated PD-1/PD-L1 axis, and increased CCL5/CXCL10 secretion were observed in Anti-mPD-1 treated mice (P<0.01), which were markedly enhanced by SY (P<0.05 or P<0.01). Furthermore, the enhanced effects of SY on inhibiting tumor cell growth, facilitating apoptosis and inflammatory cytokine releasing, suppressing the PD-1/PD-L1 axis, and inducing the CCL5/CXCL10 secretion in Anti-mPD-1 treated mixture of Luc-Hepa1-6 cells and CD3+CD8+ T cells were abolished by FAK overexpression (P<0.01). CONCLUSION: SY inhibited the progression of HCC by mediating immunological tolerance through inhibiting FAK.

Okra flowers are a good source of polysaccharides and flavonoids, with biological activities of anti-inflammatory action and modulation of the gut microbiota. Previously, we reported that flavonoid-rich extracts from okra flowers (AFE) presented effective anti-colorectal cancer (CRC) activity in CRC cells as well as xenograft models, but their role in colitis-associated cancer (CAC) is unidentified. In this study, we aimed to evaluate the effects of AFE and APE (polysaccharides extracted from okra flowers) on the CAC symptoms of azoxymethane (AOM)/dextran sodium sulfate (DSS)-intervened mice. The results showed that APE and AFE exert potent efficacy in inhibiting colitis and colorectal tumorigenesis stimulated by AOM/DSS, characterized by decreased colonic shortening, DAI score, and tumor numbers. Compared with the control group, APE/AFE alleviated the microbiota dysbiosis driven by AOM/DSS. In addition, AFE elicited its anticancer activity through regulation of NFκB/IL-6/Stat3, JAK2/Stat3, MAPKs, PI3K/AKT, and Wnt/ß-catenin signal transductions in AOM/DSS mice, which was consistent with a vitro model of CT26 cells, while APE treatment exhibited anticancer activity through regulation of Nrf2/IL-6, MAPKs, PI3K/AKT, and Wnt/ß-catenin signal transductions in the AOM/DSS mouse model. Collectively, our studies revealed, for the first time, that flavonoids and polysaccharides from okra flowers possess the ability to attenuate colitis and colorectal tumorigenesis, with them having great potential to become promising candidates against CRC.

Insufficient calcium intake during growth is a global public health concern. The aim of this study was to investigate the effects of dietary menaquinone-7 (MK-7) on bone accrual in growing Sprague-Dawley rats under calcium restriction. Following 13 weeks of treatment, various bone quality parameters, including microarchitecture, were measured. Fecal and cecal samples were subjected to microbiome (16S rRNA gene sequencing) analyses, while metabolomics analysis of the cecum and humerus samples was analyzed based on UHPLC-Q/TOF-MS. We found that calcium deficiency diminished the richness of the microbiome and disrupted microbiome composition, accompanied by an elevation in the relative abundance of Parasutterella. Furthermore, calcium insufficiency escalated the level of isovaleric acid and modified the metabolic profiles. MK-7 supplementation significantly increased the cortical thickness, cortical bone area, and the calcium content of the femur. Apart from improving bone calcium deposition and diminishing bone resorption, the mechanisms underlying the beneficial effects of MK on bone quality also involve the modulation of the host's metabolic pathways and the composition of gut microbiota. The gut-bone axis holds promise as an efficacious target for ameliorating calcium deficiency in children's bone quality, and MK-7 is a promising dietary supplement from this perspective.
RESUMEN
The liver is exposed to several harmful substances that bear the potential to cause excessive liver damage ranging from hepatitis and non-alcoholic fatty liver disease to extreme cases of liver cirrhosis and hepatocellular carcinoma. Liver ailments have been effectively treated from very old times with Chinese medicinal herbal formulations and later also applied by controlled trials in Japan. However, these traditional practices have been hardly well characterized in the past till in the last decades when more qualified studies have been carried out. Modern advances have given rise to specific molecular targets which are specifically good candidates for affecting the intricate mechanisms that play a role at the molecular level. These therapeutic regimens that mainly affect the progression of the disease by inhibiting the gene expression levels or by blocking essential molecular pathways or releasing cytokines may prove to play a vital role in minimizing the tissue damage. This review, therefore, tries to throw light upon the variation in the therapies for the treatment of benign and malignant liver disease from ancient times to the current date. Nonetheless, clinical research exploring the effectiveness of herbal medicines in the treatment of benign chronic liver diseases as well as prevention and treatment of HCC is still warranted.

Gastric cancer is one of the most common malignant tumors in the world. As the intestine is downstream of the digestive tract, the occurrence of gastric cancer may have a certain significant impact on it. Therefore, it is particularly important to find out the intestinal bacteria closely related to gastric cancer, to identify the specific flora related to gastric cancer, and to maintain the stability of the core structure of intestinal microecology in patients with gastric cancer. Based on this, the fecal samples of gastric cancer patients and healthy people were collected, and the diversity and composition of intestinal flora in patients with gastric cancer were analyzed by 16S rRNA sequencing technology. We found that there was no significant difference in the diversity and abundance of intestinal flora between gastric cancer patients and healthy people. The relative abundance of Faecalibacterium, Bifidobacterium, and Subdoligranulum in the intestinal tract of patients with gastric cancer was significantly lower than that in healthy people, while the relative abundance of Enterococcus, Streptococcus, and Bacteroides was increased. This study found that there were six kinds of intestinal microflora closely related to the occurrence of gastric cancer, which provided a theoretical basis for further exploring the pathogenesis of gastric cancer.
RESUMEN
Purpose: The goal of this study was to see if electroacupuncture was effective and safe in the management of cerebral infarction. PubMed, Embase, Cochrane Library, and Web of Science were used to conduct a comprehensive literature survey. Methods: Basic features of 7 studies were identified using the searching strategy. The investigation was found in PubMed, Embase, and Web of Science, with the most recent search being in March 2022. "Electroacupuncture," "cerebral infarction," and their permutations were among the MeSH terms and free words used. As literature, two reviewers independently used a standardized form to gather pertinent data from qualifying research. Results: 157 literatures were identified and evaluated. Electroacupuncture improved the BI score in individuals with cerebral infarction (mean difference = 0.10, 95 percent CI: 0.00-0.20, p = 0.04). Electroacupuncture enhanced BI score in individuals with cerebral infarction (mean difference = 0.10, 95 percent CI: 0.00-0.20, p = 0.04). The effects of electroacupuncture increased Fugl-Meyer index in patients with cerebral infarction (mean difference = 25.92, 95% CI: 25.28-26.56, p < 0.00001). Electroacupuncture effects decreased CSS in patients with cerebral infarction in the experiment group (mean difference = -2.10, 95% CI: -2.53--1.67, p < 0.0001). Electroacupuncture also reduced CSS individuals with cerebral infarction in the control group; however, there was no statistically significant (risk difference = 0.06, 95 percent CI: 0.02-0.13, p = 0.12). Conclusion: This study demonstrated that electroacupuncture helped decreased CSS in patients with cerebral infarction.
RESUMEN
In this study, we explored the gene expression patterns of the pituitary gland and hypothalamus of Angus cows at different growth and developmental stages by deep sequencing and we identified genes that affect bovine reproductive performance to provide new ideas for improving bovine fertility in production practice. We selected three 6-month-old (weaning period), three 18-month-old (first mating period), and three 30-month-old (early postpartum) Angus cattle. The physiological status of the cows in each group was the same, and their body conformations were similar. After quality control of the sequencing, the transcriptome analyses of 18 samples yielded 129.18 GB of clean data. We detected 13,280 and 13,318 expressed genes in the pituitary gland and hypothalamus, respectively, and screened 35 and 50 differentially expressed genes (DEGs) for each, respectively. The differentially expressed genes in both tissues were mainly engaged in metabolism, lipid synthesis, and immune-related pathways in the 18-month-old cows as compared with the 6-month-old cows. The 30-month-old cows presented more regulated reproductive behavior, and pituitary CAMK4 was the main factor regulating the reproductive behavior during this period via the pathways for calcium signaling, longevity, oxytocin, and aldosterone synthesis and secretion. A variant calling analysis also was performed. The SNP inversions and conversions in each sample were counted according to the different base substitution methods. In all samples, most base substitutions were represented by substitutions between bases A and G, and the probability of base conversion exceeded 70%, far exceeding the transversion. Heterozygous SNP sites exceeded 37.68%.

OBJECTIVES: To investigate the levels of fat-soluble vitamins A, D, and E in children with obesity and their influencing factors. METHODS: A total of 273 children with obesity who attended the Department of Clinical Nutrition, Xi'an Children's Hospital, from January 2019 to April 2021 were enrolled as the obesity group. A total of 226 children with normal body weight who underwent physical examination during the same period were enrolled as the control group. Anthropometric parameters and body composition were measured for both groups, and the serum concentrations of vitamins A, D, and E were also measured. RESULTS: Compared with the control group, the obesity group had significantly higher serum levels of vitamin A [(1.32±0.21) µmol/L vs (1.16±0.21) µmol/L, P<0.001] and vitamin E [(9.3±1.4) mg/L vs (8.3±1.2) mg/L, P<0.001] and a significant reduction in the level of 25-hydroxyvitamin D [(49±22) nmol/L vs (62±24) nmol/L, P<0.001]. In the obesity group, the prevalence rates of marginal vitamin A deficiency, vitamin D deficiency/insufficiency, and vitamin E insufficiency were 5.5% (15/273), 56.8% (155/273), and 4.0% (11/273), respectively. After adjustment for body mass index Z-score and waist-to-height ratio, serum vitamin A level was positively correlated with age (P<0.001), while vitamins E and 25-hydroxyvitamin D levels were negatively correlated with age in children with obesity (P<0.001). After adjustment for age, the serum levels of vitamin A, vitamin E and 25-hydroxyvitamin D were not correlated with degree of obesity, percentage of body fat, and duration of obesity in children with obesity, while the serum levels of vitamins A and E were positively correlated with waist-to-height ratio (P<0.001). CONCLUSIONS: There are higher serum levels of vitamins A and E in children with obesity, especially in those with abdominal obesity, while serum vitamin D nutritional status is poor and worsens with age. Therefore, vitamin D nutritional status should be taken seriously for children with obesity, and vitamin D supplementation should be performed when necessary.

Psoriasis, an immune-mediated inflammatory disease, is associated with poor pregnancy outcomes. Emerging evidence indicates that these defects are likely attributed to compromised oocyte competence. Nevertheless, little is known about the underlying associated mechanisms between psoriasis and poor oocyte quality. In this study, we construct an imiquimod-induced chronic psoriasis-like mouse model to review the effects of psoriasis on oocyte quality. We discover that oocytes from psoriasis-like mice display spindle/chromosome disorganization, kinetochore-microtubule mis-attachment, and aneuploidy. Importantly, our results show that melatonin supplement in vitro and in vivo not only increases the rate of matured oocytes but also significantly attenuates oxidative stress and meiotic defects by restoring mitochondrial function in oocytes from psoriasis-like mice. Altogether, our data uncover the adverse effects of psoriasis symptoms on oocytes, and melatonin supplement ameliorates oxidative stress and meiotic defects of oocytes from psoriatic mice.

Background: Alzheimer's disease (AD) is the most common cause of dementia. The emerging data suggest that cognitive decline occurred in the setting of Aß accumulation with synaptic dysfunction, which started to happen at preclinical stages. Then, presymptomatic intervention is more critical to postponing AD processing. Traditional Chinese medicine has a long history of treating and preventing dementia. Findings have shown that the decoction of Panax notoginseng and Gardenia jasminoides Ellis enhances memory functions in patients with stroke, and their main components, Panax notoginseng saponins (PNS) and geniposide (GP), improved memory abilities in experimental AD models. Since herbal medicine has advantages in protection with few side effects, we wish to extend observations of the NeuroProtect (NP) formulation for reducing amyloid-ß and restoring synaptic structures in APP/PS1 transgenic mice. Methods: APP/PS1 transgenic mice and their wild-type littermates were fed with control, NP, and their components from 4 to 7 months of age. We assessed the synaptic structure by Golgi staining, analyzed the amyloid deposits by Thioflavin-S staining, and measured related protein levels by Western blot or ELISA. We used the Morris water maze and shuttle box test to evaluate cognitive functions. Results: Compared to WT mice, APP/PS1 mice are characterized by the accumulation of amyloid plaques, reducing synaptic structure richness and memory deficits. NP prevents these changes and ameliorates cognitive deficits. These effects may have been due to the contribution of its components by inhibition of insoluble amyloid-ß deposition and restoration of synaptic structures. Conclusion: These findings reveal a beneficial effect of NP on AD progression under an early intervention strategy and provide a food supplement for AD prevention.
RESUMEN
With the accumulation of knowledge on the relation between psychological stress and gut microbiota, there is growing interest in controlling stress and/or mood disorders via probiotic supplementation. We aimed to examine the effect of probiotic Bifidobacterium bifidum TMC3115 (TMC3115) supplementation using a sub-chronic and mild social defeat stress murine model in this study. TM3115 supplementation maintained body weight gain and alleviated a polydipsia-like symptom induced by the stress. In the analyses of fecal and cecal bacterial profiles, expansions of Proteobacteria in stressed mice and increases in Actinobacteria and Bifidobacterium in mice supplemented with TMC3115 were observed. There was no marked difference in the diversity of cecal bacteria between the tested mice. Elevated serum levels of inflammatory markers such as tumor necrosis factor (TNF)-α and interleukin (IL)-6 were observed in the stressed mice, while TMC3115 only reduced the IL-6 level. These findings suggest that TMC3115 supplementation confers tolerance to psychosocial stress in the host through modulation of the gut microbiota and alleviation of stress-induced inflammatory responses. Furthermore, it may be expected to exert prevention and treatment of disorders related to peripheral IL-6, including depression.

BACKGROUND: Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology is widely used in disease treatment and medicinal plant improvements due to its advantages, such as easy operation, low time consumption, and high efficiency. However, potential off-target risks still exist in practical applications and need to be solved urgently. OBJECTIVES: This study aimed to review the application progress of CRISPR/Cas9 technology in the field of disease treatment and medicinal agriculture in recent years. Furthermore, the study discusses the ways to reduce the off-target effect of CRISPR/Cas9 technology, providing a reference for the further application of this technology. METHODS: CiteSpace software was used to analyze relevant literature data from 2013 to August 2021, and search results were retrieved from Web of Science, PubMed, and CNKI databases. RESULTS: In the field of disease treatment, CRISPR/Cas9 technology has great potential to cure challenging human diseases and has been widely used in drug target development, drug design, and screening. In crop breeding, CRISPR/Cas9 accelerates the improvement of crop varieties and shortens the number of years of crop breeding. By adjusting the length and GC content of sgRNA and changing the concentration of Cas9/sgRNA complex to reduce the off-target effect of CRISPR/Cas9 technology, the target genes can be manipulated more accurately. CONCLUSION: CRISPR/Cas9 technology is an indispensable and key technology in the field of disease treatment and medicinal plants. With the in-depth study of the off-target effect, CRISPR/Cas9 technology can have broader application prospects in the fields of medicine and medicinal agriculture.

The treatment of cancer mainly involves surgical excision supplemented by radiotherapy and chemotherapy. Chemotherapy drugs act by interfering with tumor growth and inducing the death of cancer cells. Anti-tumor drugs were developed to induce apoptosis, but some patient's show apoptosis escape and chemotherapy resistance. Therefore, other forms of cell death that can overcome the resistance of tumor cells are important in the context of cancer treatment. Ferroptosis is a newly discovered iron-dependent, non-apoptotic type of cell death that is highly negatively correlated with cancer development. Ferroptosis is mainly caused by the abnormal increase in iron-dependent lipid reactive oxygen species and the imbalance of redox homeostasis. This review summarizes the progression and regulatory mechanism of ferroptosis in cancer and discusses its possible clinical applications in cancer diagnosis and treatment.
RESUMEN
The purpose of this study was to explore the hypouricemic effect in hyperuricemia mice of triterpenoid acids from Inonotus obliquus (TAIO), and decipher of the underlying xanthine oxidase inhibitory mechanism. Measurement of xanthine oxidase (XO) inhibitory activity was assayed. Organ indexes and serum biochemical indicators were measured in potassium oxonate-induced hyperuricemia mice. Studies showed that TAIO had the strong inhibitory effect on XO activity, and its inhibition type was mixed and reversible. In vivo, TAIO decreased efficiently uric acid level, hepatic XO, serum blood urea nitrogen activities in hyperuricemia mice. Indicating that TAIO may ameliorate kidney damage and relieve inflammation in hyperuricemic mice, and had the inhibitory effect on XO activity. Furthermore, eight triterpenoids were identified by Ultra performance liquid chromatography electrospray quadrupole time of flight mass spectrometry. These findings proved that triterpenoids from Inonotus obliquus would have potential biological characteristics and effect on controlling hyperuricemia and gout as an active supplement. PRACTICAL APPLICATIONS: There are a large amount of evidence indicating that hyperuricemia and gout are related to the hypertension and obesity. And gout and hyperuricemia are also possible connection with cardiovascular disease and metabolic syndrome. Currently, xanthine oxidase is the target of many kinds of chemical drugs at present, but the therapeutic drugs used in clinical medicine will produce more or less side effects. Therefore, the aim of this study was to explore the material basis of effective substances for reducing uric acid in Inonotus obliquus and to evaluate its effect. This study can provide a promising application of Inonotus obliquus in the fields of functional foods or medicines for gout and hyperuricemia.

The effect of perioperative acupuncture on accelerating gastrointestinal function recovery has been reported in colorectal surgery and distal gastrectomy (Billroth-II). However, the evidence in pancreatectomy and other gastrectomy is still limited. A prospective, randomized controlled trial was conducted between May 2018 and August 2019. Consecutive patients undergoing pancreatectomy or gastrectomy in our hospital were randomly assigned to the electroacupuncture (EA) group and the control group. The patients in the EA group received transcutaneous EA on Bai-hui (GV20), Nei-guan (PC6), Tian-shu (ST25), and Zu-san-li (ST36) once a day in the afternoon, and the control group received sham EA. Primary outcomes were the time to first flatus and time to first defecation. In total, 461 patients were randomly assigned to the groups, and 385 were analyzed finally (EA group, n = 201; control group, n = 184). Time to first flatus (3.0 ± 0.7 vs 4.2 ± 1.0, P < 0.001) and first defecation (4.2 ± 0.9 vs 5.4 ± 1.2, P < 0.001) in the EA group were significantly shorter than those in the control group. Of patients undergoing pancreatectomy, those undergoing pancreaticoduodenectomy and intraoperative radiation therapy (IORT) surgery benefitted from EA in time to first flatus (P < 0.001) and first defecation (P < 0.001), while those undergoing distal pancreatectomy did not (P flatus=0.157, P defecation=0.007) completely. Of patients undergoing gastrectomy, those undergoing total gastrectomy and distal gastrectomy (Billroth-II) benefitted from EA (P < 0.001), as did those undergoing proximal gastrectomy (P=0.015). Patients undergoing distal gastrectomy (Billroth-I) benefitted from EA in time to first defecation (P=0.012) but not flatus (P=0.051). The time of parenteral nutrition, hospital stay, and time to first independent walk in the EA group were shorter than those in the control group. No severe EA complications were reported. EA was safe and effective in accelerating postoperative gastrointestinal function recovery. Patients undergoing pancreaticoduodenectomy, IORT surgery, total gastrectomy, proximal gastrectomy, or distal gastrectomy (Billroth-II) could benefit from EA. This trial is registered with NCT03291574.
RESUMEN
Swertia mileensis, known as Qing-Ye-Dan (QYD), has been documented in Chinese Pharmacopoeia to cure hepatitis. Interestingly, its announced main active component, swertiamarin, could not be detected in the decoction, which indicated that the efficacy of QYD might be attributed to heat-transformed products of swertiamarin (HTPS). Further investigation on HTPS led to the isolation of sweritranslactone D (1), a novel secoiridoid dimer possessing a tetracyclic lactone skeleton, with better hepatoprotective activity than N-acetyl-L-cysteine in vitro.

BACKGROUND: The National Comprehensive Cancer Network's Rectal Cancer Guideline Panel recommends American Joint Committee of Cancer and College of American Pathologists (AJCC/CAP) tumor regression grading (TRG) system to evaluate pathologic response to neoadjuvant chemoradiotherapy for locally advanced rectal cancer (LARC). Yet, the clinical significance of the AJCC/CAP TRG system has not been fully defined. MATERIALS AND METHODS: This was a multicenter, retrospectively recruited, and prospectively maintained cohort study. Patients with LARC from one institution formed the discovery set, and cases from external independent institutions formed a validation set to verify the findings from discovery set. Overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were assessed by Kaplan-Meier analysis, log-rank test, and Cox regression model. RESULTS: The discovery set (940 cases) found, and the validation set (2,156 cases) further confirmed, that inferior AJCC/CAP TRG categories were closely /ccorrelated with unfavorable survival (OS, DFS, LRFS, and DMFS) and higher risk of disease progression (death, accumulative relapse, local recurrence, and distant metastasis) (all p < .05). Significantly, pairwise comparison revealed that any two of four TRG categories had the distinguished survival and risk of disease progression. After propensity score matching, AJCC/CAP TRG0 category (pathological complete response) patients treated with or without adjuvant chemotherapy displayed similar survival of OS, DFS, LRFS, and DMFS (all p > .05). For AJCC/CAP TRG1-3 cases, adjuvant chemotherapy treatment significantly improved 3-year OS (90.2% vs. 84.6%, p < .001). Multivariate analysis demonstrated the AJCC/CAP TRG system was an independent prognostic surrogate. CONCLUSION: AJCC/CAP TRG system, an accurate prognostic surrogate, appears ideal for further strategizing adjuvant chemotherapy for LARC. IMPLICATIONS FOR PRACTICE: The National Comprehensive Cancer Network recommends the American Joint Committee of Cancer and College of American Pathologists (AJCC/CAP) tumor regression grading (TRG) four-category system to evaluate the pathologic response to neoadjuvant treatment for patients with locally advanced rectal cancer; however, the clinical significance of the AJCC/CAP TRG system has not yet been clearly addressed. This study found, for the first time, that any two of four AJCC/CAP TRG categories had the distinguished long-term survival outcome. Importantly, adjuvant chemotherapy may improve the 3-year overall survival for AJCC/CAP TRG1-3 category patients but not for AJCC/CAP TRG0 category patients. Thus, AJCC/CAP TRG system, an accurate surrogate of long-term survival outcome, is useful in guiding adjuvant chemotherapy management for rectal cancer.
