RESUMO
Intestinal macrophages play crucial roles in both intestinal inflammation and immune homeostasis. They can adopt two distinct phenotypes, primarily determined by environmental cues. These phenotypes encompass the classically activated pro-inflammatory M1 phenotype, as well as the alternatively activated anti-inflammatory M2 phenotype. In regular conditions, intestinal macrophages serve to shield the gut from inflammatory harm. However, when a combination of genetic and environmental elements influences the polarization of these macrophages, it can result in an M1/M2 macrophage activation imbalance, subsequently leading to a loss of control over intestinal inflammation. This shift transforms normal inflammatory responses into pathological damage within the intestines. In patients with ulcerative colitis-associated colorectal cancer (UC-CRC), disorders related to intestinal inflammation are closely correlated with an imbalance in the polarization of intestinal M1/M2 macrophages. Therefore, reinstating the equilibrium in M1/M2 macrophage polarization could potentially serve as an effective approach to the prevention and treatment of UC-CRC. This paper aims to scrutinize the clinical evidence regarding Chinese medicine (CM) in the treatment of UC-CRC, the pivotal role of macrophage polarization in UC-CRC pathogenesis, and the potential mechanisms through which CM regulates macrophage polarization to address UC-CRC. Our objective is to offer fresh perspectives for clinical application, fundamental research, and pharmaceutical advancement in UC-CRC.

@#Abstract: Objective This article summarizes the clinical characteristics and diagnosis and treatment experience of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 in Hainan Province. Methods The clinical data and treatment of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 admitted to Haikou designated hospital on August 15, 2022 were retrospectively analyzed. Results A 107-year-old female patient was admitted to the hospital with "fever and cough for 1 day". Two of her family members have infected with COVID-19. The patient initially developed fever, accompanied by cough, expectoration, a little white sticky sputum, accompanied by sore throat, muscle pain, fatigue. Nucleic acid test was positive in throat swab, indicating Omicron variant BA.5.1.3 infection. The patient was diagnosed as mild COVID-19 and treated with antiviral therapy, Chinese medicine conditioning, anticoagulation, electrolyte disorder regulation and symptomatic treatment for 9 days. The patient's clinical symptoms were relieved, and she was cured and discharged after two negative nucleic acid tests. One week later, the patient recovered well. Conclusions Omicron variant BA.5.1.3 is highly infectious, and comprehensive treatment such as antiviral treatment and traditional Chinese medicine treatment has achieved good efficacy. For elderly patients, attention should be paid to maintaining the stability of organ function and internal environment, which is helpful to improve the prognosis of patients.
RESUMO
OBJECTIVE: To evaluate the effects of an integrated childbirth education intervention on reducing childbirth fear, anxiety, and depression, and improving dispositional mindfulness. DESIGN: A two-arm parallel, single-blind randomised controlled trial. SETTING: A teaching hospital in Northern Taiwan. PARTICIPANTS: Pregnant women ≥ 20 years of age with a singleton pregnancy (12-24 weeks gestation) and their support partners were recruited. All women included in the study had a score of ≥ 7 points on a fear of childbirth visual analogue scale. INTERVENTIONS: The intervention group (n = 53) received an 8-week course in a childbirth education programme, which included (1) childbirth education using simulation-based learning that highlighted coping with labour pain and (2) instruction in mindfulness breathing, body scans, stretching, sitting meditation, and mindfulness walking. Support partners were invited to participate. The control group (n = 53) received the usual standard prenatal care. MEASUREMENTS: The primary outcome of fear of childbirth was assessed using the Wijma Delivery Expectancy/Experience Questionnaire. The secondary outcomes of anxiety, depression, and dispositional mindfulness were assessed with the Edinburgh Postpartum Depression Scale, State-Trait Anxiety Inventory Scale, and the Mindful Attention Awareness Scale, respectively. Repeated data were collected at baseline, 36 weeks gestation, and 1 week postpartum. FINDINGS: Ninety-one mothers completed the study, with a mean age of 33.9 years (SD = 4.4), and most were primipara (n = 83). The baseline measurements did not differ between the groups. Compared with the control group, there were significant differences in all measures from baseline for the intervention group: the scores were significantly lower for fear of childbirth (mean difference (MD) =-14.8 â¼ -23.7, p < .01), symptoms of anxiety (MD =-7.4 â¼ -6.4, p < .01), and depression (MD =-3.7 â¼ -3.5, p < .01); the levels of dispositional mindfulness were significantly higher (MD =4.9 â¼ 5.7, p < .01) at 36 weeks gestation, and 1 week postpartum. CONCLUSION AND IMPLICATIONS FOR PRACTICE: The 8-week integrated childbirth education intervention was effective in reducing the fear of childbirth in pregnant women. The mindfulness techniques were easily learnt and applied by the participants. Using these techniques during pregnancy and labour enhanced participants' mental health and coping. The integrated childbirth education which includes pregnant women and their support partners could be easily taught by midwives in other contexts.

Recent studies have suggested the potency of berberine (BBR) for multiple cancer treatments, including multiple myeloma (MM). However, the direct target and underlying mechanism of BBR remain largely understood in MM. Here, we demonstrated that BBR inhibited cell proliferation and acted synergistically with bortezomib in MM.1S cells. BBR treatment induced MM cell cycle arrest by downregulating several cell cycle-related proteins. Murine double minute 2 (MDM2) as a BBR-binding protein was identified by surface plasmon resonance image (SPRi) analysis and molecular docking. Overexpression of MDM2 is associated with MM progression and a poor prognosis. Knockdown MDM2 by siRNA transfection can repress MM malignant progression and attenuate the BBR sensitivity to MM.1S cells. BBR treatment induced the degradation of MDM2 through the ubiquitin-proteasome system and reactivated P53/P21 in MM cells. Overall, our data has illustrated that MDM2, as a binding protein of BBR for the first time, may serve as a potential therapeutic option for MM.

Objectives: The research aim was to perform a systematic review and meta-analysis evaluating the ability of acupressure to reduce anxiety. Design: Randomized controlled trials were obtained through a search of electronic medical databases (four in English and one in Chinese) from inception to October 5, 2020. Two authors searched the databases, evaluated studies' methodological quality, and performed data extraction independently. The final studies for analysis were identified after discussion with the third author. Results: We obtained 27 studies for our systematic review and meta-analysis. Eight studies had a low overall risk of bias, and 13 had some bias concerns with methodological quality. According to the results, acupressure significantly reduced patient anxiety (standardized mean difference = 1.152; 95% confidence interval: 0.847-1.459, p < 0.001), and the study heterogeneity was high (Q = 299.74, p < 0.001, I2 = 91.333%). Two studies reported acupressure-associated adverse events. We also performed a sensitivity analysis by omitting one outlier study, which had the largest effect size; however, high heterogeneity remained (I2 = 87.816%). A subgroup analysis revealed significant differences between participant types (Q = 46.573, p < 0.001), levels of methodological quality (Q = 6.228, p = 0.044), and massage equipment (Q = 4.642, p = 0.031). Conclusions: Our meta-analysis suggests that acupressure can alleviate anxiety. Acupressure was more effective for inpatients and preoperative patients when finger massage was applied. In individuals with anxiety and a stable hemodynamic status, acupressure could be a promising treatment option. However, the substantial heterogeneity across studies means that any inference from the results should be performed cautiously.

BACKGROUND: Degenerative osteoarthritis (OA) often leads to pain and stiffness of the affected joints, which may affect the physical performance and decrease the quality of life of people with degenerative knee OA. Compared to traditional exercise, tai chi is a safe exercise with slow movements which can facilitate physical functioning and psychological well being, and might be suitable for improving the physical activities of older adults with knee OA. Therefore, this study investigated the impacts of tai chi exercise on the functional fitness of community-dwelling older adults with degenerative knee OA. METHODS: Sixty-eight community-dwelling older adults with knee OA were recruited from the local community to participate in this randomized controlled clinical trial. All subjects were randomly assigned to either an TCE group that practiced tai chi exercise (TCE) (n = 36) or a control group (CON) (n = 32) that received regular health education programs twice per week for 12 weeks. Outcome measurements were determined using functional fitness tests before and after the intervention, including a 30-s chair stand (number of repeats), 30-s arm-curl (number of repeats), 2-min step (number of steps), chair sit-and-reach (reaching distance, cm), back-scratch flexibility (distance between hands, cm), single-leg stand (time, s), functional reach (reaching distance, cm), 8-foot up-and-go (time, s), and 10-m walk tests (time, s). Pre-post comparisons of functional fitness were analyzed using the ANCOVA test with SPSS software version 18.0. RESULTS: Results revealed that participants' functional fitness in the TCE group had significantly higher adjusted mean post-tests scores than that in the CON group after the intervention, including the 8-foot up-and-go (s) (mean difference [MD]=-2.92 [-3.93, -1.91], p = 2.39*10- 7), 30-s arm curl (MD = 4.75 (2.76, 6.73), p = 1.11*10- 5), 2-min step (MD = 36.94 [23.53, 50.36], p = 7.08*10- 7), 30-s chair stand (MD = 4.66 [2.97, 6.36], p = 6.96*10- 7), functional-reach (MD = 5.86 [3.52, 8.20], p = 4.72*10- 6), single-leg stand with eyes closed (MD = 3.44 [1.92, 4.97], p = 2.74*10- 5), chair sit-and-reach (MD = 3.93 [1.72, 6.15], p = 0.001), and single-leg stand with eyes opened (MD = 17.07 [6.29, 27.85], p = 0.002), with large effect sizes (η²=0.14 ~ 0.34). CONCLUSIONS: Community-dwelling older adults with knee OA in the TCE group had better functional fitness performances after the 12-week tai chi intervention than those receiving only health education.

This study aims to establish a quantitative method of 4 aristolochic acids-DNA adducts in mice kidney and liver based on high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) for monitoring the content changes of aristolochic acids-DNA adducts. A Shiseido Capcellpak AQ C_(18) column(3 mm×100 mm, 3 µm) was used, with a mixture of 0.2% acetic acid-5 mmol·L~(-1) ammonium acetate as the aqueous phase and methanol as the organic phase for gradient elution. The multiple reaction monitoring(MRM) scanning method under positive mode by electrospray ionization(ESI) was performed for the detection of the aristolochic acids-DNA adducts which formed by combining aristolochic acid â /â ¡ with deoxyadenosine, deoxyguanosine, and deoxycytidine, respectively. Balb/c mice were given Guanmutong extract by gavage, and the relative content of aristolochic acids-DNA adducts in liver and kidney samples were analyzed within 60 days. It was found that the concentration of 4 aristolochic acids-DNA adducts in the kidney was significantly higher than that in the liver, and there were about 15.87 adducts in per 1×10~6 normal deoxynucleosides, which was 4.5-7.5 times than that of the liver. What's more, some adducts can still be detected on the 30 th day after administration. The concentration of the adducts in the liver was highest on the first day after administration, and a second peak appeared during the 7 th to 14 th days. The results indicated that aristolochic acids-DNA adducts are difficult to eliminate in vivo, and it is of great significance to study the mechanism of liver and kidney injury of aristolochic acid.

PURPOSE: The objective of this study was to conduct a systematic review and meta-analysis to examine the effects of aromatherapy on sleep improvements. METHODS: A search of randomized controlled trials was conducted in four English and two Chinese medical electronic databases. Two authors independently performed the search, assessed the methodological quality, and extracted data. Then, final studies were selected after consensus with the third author. RESULTS: In total, 31 trials met the inclusion criteria, of which four had low risk, while the overall bias in 26 was uncertain in terms of methodological quality. The heterogeneity was high among the trials (Q = 341.544, p < 0.001, I2â¯=â¯91.216%). There was a significant effect of aromatherapy on sleep quality (Hedges's gâ¯=â¯1.103 (95% confidence interval: 0.813Ë1.393, p < 0.001). There was a publication bias (Egger's regression interceptâ¯=â¯7.127, t = 3.055, p = 0.004 and Begg test, Kendall's tau with continuity correction, tauâ¯=â¯0.335 and Zâ¯=â¯2.651, p = 0.008). The subgroup analysis showed that there was a significant difference in the methodological quality among different studies (Qâ¯=â¯18.350, pâ¯<⯠0.001). Sensitivity analyses still revealed high heterogeneity after omitting one study at a time. CONCLUSIONS: The results showed that aromatherapy can be applied by clinical staff to effectively improve sleep quality. However, because there was a high degree of heterogeneity among studies, the inferences of the results need to be applied with caution.

The purpose of this study was to investigate the effects that listening and not listening to music had on pain relief, heart rate variability (HRV), and knee range of motion in total knee replacement (TKR) patients who underwent continuous passive motion (CPM) rehabilitation. We adopted a single-group quasi-experimental design. A sample of 49 TKR patients listened to music for 25 min during one session of CPM and no music during another session of CPM the same day for a total of 2 days. Results indicated that during CPM, patients exhibited a significant decrease in the pain level ( p < .05), an increase in the CPM knee flexion angle ( p < .05), a decrease in the low-frequency/high-frequency ratio (LF/HF) and normalized LF (nLF) of the HRV ( p < .01), and an increase in the normalized HF (nHF) and standard deviation of all normal-to-normal intervals (SDNN; p < .01) when listening to music compared with no music. This study demonstrated that listening to music can effectively decrease pain during CPM rehabilitation and improve the joint range of motion in patients who underwent TKR surgery.

To exert pharmacological effects, no matter therapeutic effect or toxic/side effect, it's necessary to achieve enough plasma concentration. Chinese medical compounds, which contain various ingredients, influence the metabolism of some active ingredients through the interaction of ingredients to improve curative effects or reduce toxic/side effects. Pharmacokinetics can be used to explore how Chinese medical compounds influence the in vivo metabolism of some active ingredients to achieve better curative effects.

AIM: This study investigated the effects of music listening on the anxiety, heart rate variability (HRV), and joint range of motion (ROM) of patients undergoing continuous passive motion (CPM) after total knee replacement surgery. METHOD: An experimental design was used. Participants in the experimental group (n = 49) listened to music from 10 min before receiving CPM until the end of the session (25 min in total) on the first and second day following surgery, whereas participants in the control group (n = 42) did not listen to music but rested quietly in bed starting 10 min before and throughout CPM. RESULTS: Compared with the control group, the experimental group exhibited significantly lower anxiety levels (p < .05) and increased CPM angles (p < .05) during treatment and increased active flexion ROM (p < .05) upon discharge. The low-frequency (LF)/high-frequency (HF) power ratio, normalized LF HRV, and normalized HF HRV of the two groups differed significantly, indicating that the patients in the experimental group had greater parasympathetic activity compared with those in the control group. CONCLUSION: Music listening can effectively reduce patient anxiety and enhance the ROM of their joints during postoperative rehabilitation. Health-care practitioners should consider including music listening as a routine practice for postoperative rehabilitation following orthopedic surgery.

This study explored the curative effect and underlying mechanisms of a traditional Chinese medicine compound prescription, Bushen-Yizhi formula (BSYZ), in ibotenic acid (IBO)-induced rats. Morris water maze and novel object recognition tests showed that BSYZ significantly improved spatial and object memory. Brain immunohistochemistry staining showed that BSYZ significantly up-regulated expression of choline acetyltransferase (ChAT) and nerve growth factor (NGF) in the hippocampus and cortex. The protein tyrosine kinase high-affinity receptor TrkA was slightly increased in the hippocampus and cortex, and significantly enhanced in the nucleus basalis of Meynert (NBM) after BSYZ intervention. The immunoreactivity of the p75 low-affinity receptor in BSYZ-treated rats was significantly strengthened in the cortex. Similar expression trends of nerve growth factor (NGF), TrkA, and p75 mRNA were observed in the hippocampus and cortex. Additionally, BSYZ reversed IBO-induced disorders of acetylcholine (ACh) levels, ChAT, and cholinesterase (ChE) in the cortex, which was consistent with the changes in mRNA levels of ChAT and acetylcholinesterase (AChE). Expression of ChAT and AChE proteins and mRNA in the hippocampus was up-regulated, whereas the apoptosis-relative protein cleaved caspase-3 was decreased after administration of BSYZ. Moreover, changes in cell death were confirmed by histological morphology. Thus, the results indicated that the BSYZ formula could ameliorate memory impairments in IBO-induced rats, and it exerted its therapeutic action probably by modulating cholinergic pathways, NGF signaling, and anti-apoptosis. Overall, it is suggested that the BSYZ formula might be a potential therapeutic approach for the treatment of Alzheimer's disease (AD) and other cholinergic impairment-related diseases.

BACKGROUND: We performed the first meta-analysis of clinical studies by investigating the effects of eye-movement desensitization and reprocessing (EMDR) therapy on the symptoms of posttraumatic stress disorder (PTSD), depression, anxiety, and subjective distress in PTSD patients treated during the past 2 decades. METHODS: We performed a quantitative meta-analysis on the findings of 26 randomized controlled trials of EMDR therapy for PTSD published between 1991 and 2013, which were identified through the ISI Web of Science, Embase, Cochrane Library, MEDLINE, PubMed, Scopus, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature electronic databases, among which 22, 20, 16, and 11 of the studies assessed the effects of EMDR on the symptoms of PTSD, depression, anxiety, and subjective distress, respectively, as the primary clinical outcome. RESULTS: The meta-analysis revealed that the EMDR treatments significantly reduced the symptoms of PTSD (g =â-0.662; 95% confidence interval (CI): -0.887 to -0.436), depression (g =â-0.643; 95% CI: -0.864 to -0.422), anxiety (g =â-0.640; 95% CI: -0.890 to -0.390), and subjective distress (g =â-0.956; 95% CI: -1.388 to -0.525) in PTSD patients. CONCLUSION: This study confirmed that EMDR therapy significantly reduces the symptoms of PTSD, depression, anxiety, and subjective distress in PTSD patients. The subgroup analysis indicated that a treatment duration of more than 60 min per session was a major contributing factor in the amelioration of anxiety and depression, and that a therapist with experience in conducting PTSD group therapy was a major contributing factor in the reduction of PTSD symptoms.

BushenYizhi formula (BSYZ), a traditional Chinese medicine formula consisting of six herbs has been reported to possess a neuroprotective effect. The present study aimed to investigate the effects of BSYZ on learning and memory abilities, as well as oxidative stress and neuronal apoptosis in the hippocampus of scopolamine (SCOP)induced senescence in mice, in order to reveal whether BSYZ is a potential therapeutic agent for Alzheimer's disease (AD). A highperformance liquid chromatography (HPLC) fingerprint was applied to provide a chemical profile of BSYZ. Extracts of BSYZ were orally administered to mice with SCOPinduced memory impairment for two weeks. The learning and memory abilities were determined by the Morris water maze test. The oxidant stressrelated indices, such as activity of superoxide dismutase (SOD) and levels of glutathione (GSH) and malondialdehyde (MDA) were examined in hippocampus of SCOPtreated mice. The cell death ratio was assessed by TUNEL staining, while apoptoticrelated proteins including Bcl2 and Bax were determined by immuno-fluorescent staining and western blot analysis. Caspase3 was determined by western blot analysis. Consequently, a chromatographic condition, which was conducted at 35ËC with a flow rate of 0.8 ml/min on the Gemini C18 column with mobile phase of acetonitrile and waterphosphoric acid (100:0.1, v/v), was established to yield common fingerprint chromatography under 203 nm with a similarity index of 0.986 within 10 batches of BSYZ samples. BSYZ at a dose of 2.92 g/kg significantly improved the cognitive ability, restored the abnormal activity of SOD and increased the levels of MDA and GSH induced by SCOP. Moreover, the neural apoptosis in the hippocampus of SCOPtreated mice was reversed by BSYZ by regulating the expression of Bcl2, Bax and caspase3. The results demonstrated that BSYZ had neuroprotective effects in SCOPinduced senescence in mice by ameliorating oxidative stress and neuronal apoptosis in the brain, supporting its potential in AD treatment.

Alzheimer's disease (AD) is a neurodegenerative disease that is characterized by the accumulation of senile plaque and neurofibrilary tangle formation in the brain, including the cerebral cortex and hippocampus. Nowadays, the first-line treatment for AD is the application of acetylcholinesterase inhibitors. However, acetylcholinesterase inhibitors are basically anti-symptomatic for a limited aspect of AD pathology and are associated with serious side-effects. With the advantage of multiple targets, pathways and systems, Chinese herbal compounds hold promising potential for the development of drugs for the treatment of AD. Over the past few years, with the development of Chinese herbal compounds and in vitro pharmacological studies, cell-based disease models are one of the main methods used to screen Chinese herbal compounds for potential efficacy. Testing the efficacy of possible anti-Alzheimer's disease drugs and the development of new drugs are hindered by the lack of objective high-throughput screening methods. Currently, the assessment of the effects of drugs is usually made by MTT assays, involving laborious, subjective, low-throughput methods. Herein, we suggest a novel application for a real-time cell monitoring device (xCELLigence) that can simply and objectively assess the effective composition of Chinese herbal compounds by assessing amyloid-ß peptide Aß1-42-induced apoptosis in PC12 cells. We detected the proliferation and motility of the cells using a fully automated high-throughput and real-time system. We quantitatively assessed cell motility and determined the real-time IC50 values of various anti-AD drugs that intervene in several developmental stages of Aß1-42-induced apoptosis in PC12 cells, Then, we identified the optimal time phase by curative efficacy. Our data indicate that this technique may aid in the discovery and development of novel anti-Alzheimer's disease drugs. It is possible to utilize a similar technique to measure changes in electrical impedance as cells attach and spread in a culture dish covered with a gold microelectrode array that covers approximately 80% of the area on the bottom of a well. As cells attach and spread on the electrode surface, it leads to an increase in electrical impedance of 9-12. The impedance is displayed as a dimensionless para-meter termed the cell index, which is directly proportional to the total area of tissue culture well that is covered by the cells. Hence, the cell index can be used to monitor cell adhesion, spreading, morphological variation and cell density.

OBJECTIVE: To explore the effect of composite salvia injection (CSI) on platelet parameters in children with anaphylactoid purpura (AP) and its clinical significance. METHODS: One hundred and fifty children with AP were assigned to two groups, 80 in Group A and 70 in Group B. They were treated, respectively, with conventional therapy only or conventional therapy combined with CSI. Their platelet parameters, including blood platelet count (BPC), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) were determined at the acute stage and convalescent stage, respectively. RESULTS: At the acute stage, the BPC in AP children of both groups was in the normal range, but significant abnormality was shown in the levels of MPV, PDW and PCT. As for comparisons of these parameters at the convalescent stage, significant difference between the two groups was also shown in terms of MPV, PDW and PCT (P<0.05 or P<0.01). CONCLUSION: Although platelet shows no quantitative change in the pathogenic process of AP, important functional changes are surely existent. CSI could promote the normalization of platelet function.
