Health effects of social connectedness in older adults living in congregate long-term care settings: A systematic review of quantitative and qualitative evidence.

BACKGROUND: The overall impact of social connectedness on health outcomes in older adults living in nursing homes and assisted living settings is unknown. Given the unclear health impact of social connectedness for older adults in congregate long-term care settings worldwide, a comprehensive systematic review is required to evaluate the overall relationship between social connectedness and health outcomes for them. OBJECTIVES: The purpose of this article was to synthesize the literature regarding the health impact of social connectedness among older adults living in nursing homes or assisted living settings. METHODS: Using PRISMA guidelines, we identified eligible studies from Scopus, MEDLINE, PsycINFO, CINAHL and Cochrane databases (1990-2021). Bias and quality reporting assessment was performed using standardized criteria for cohort, cross sectional and qualitative studies. At each stage, ≥ 2 researchers conducted independent evaluations. RESULTS: Of the 7350 articles identified, 25 cohort (follow-up range: 1 month-11 years; with two also contributing to cross sectional), 86 cross sectional, eight qualitative and two mixed methods were eligible. Despite different instruments used, many residents living in nursing homes and assisted living settings had reduced social engagement. Quantitative evidence supports a link between higher social engagement and health outcomes most studied (e.g. depression, quality of life). Few studies evaluated important health outcomes (e.g. cognitive and functional decline). Most cohort studies showed that lack of social connectedness accelerated time to death. CONCLUSIONS: Social connectedness may be an important modifiable risk factor for adverse health outcomes for older adults living in nursing homes and assisted living facilities. Most studies were cross sectional and focused on quality of life and mental health outcomes. Longitudinal studies suggest that higher social engagement delays time to death. Evidence regarding other health outcomes important to older adults was scant and requires further longitudinal studies.

Supporting Diverse Family Caregivers: Key Stakeholder Perspectives.

This study aimed to understand the perspectives of key stakeholders regarding strategies for better supporting culturally and ethnically diverse family caregivers, aiming to incorporate them into the Recognize, Assist, Include, Support, and Engage (RAISE) Family Caregivers Advisory Council's proposed National Strategy. The Strategy, published in 2022, identified priority actions to support the growing population of people providing unpaid care to people of all ages with disabilities, with a goal of improving the health and well-being of both the family caregiver and the person receiving support. Researchers conducted extensive outreach to purposively diverse stakeholder organizations, using six stakeholder strategy sessions with representatives from 42 groups in December 2020 to identify preliminary themes. During July-October 2021, 17 key informant interviews and 16 stakeholder listening sessions were held, involving 103 different organizations. Qualitative data analysis using an inductive approach was used to identify key themes. A significant issue for diverse caregivers is widespread lack of self-identification as caregivers, which is tied to a lack of awareness of potentially helpful services and supports; culturally appropriate outreach is critical to ensure access to services, as well as access to centralized resources and funding for community- and faith-based organizations. A community health worker model was recommended. Tailored activities, involving trusted community- and faith-based groups, as well as investments in caregiver- and culturally-specific supports, are critical for reaching the diverse family caregivers who most need supports. Raising awareness of caregiving among and taking advantage of the expertise of professionals working with diverse communities is also crucial.

[Excess Oxygen Supply for Different Time Periods Affect Energy Metabolism in Rat Alveolar Epithelial Type â ¡ Cells].

Objective To observe the effect of excess oxygen supply for different time periods on the mitochondrial energy metabolism in alveolar epithelial type Ⅱ cells. Methods Rat RLE-6TN cells were assigned into a control group (21% O2 for 4 h) and excess oxygen supply groups (95% O2 for 1,2,3,and 4 h,res-pectively).The content of adenosine triphosphate (ATP),the activity of mitochondrial respiratory chain complex V,and the mitochondrial membrane potential were determined by luciferase assay,micro-assay,and fluorescent probe JC-1,respectively.Real-time fluorescence quantitative PCR was employed to determine the mRNA levels of NADH dehydrogenase subunit 1 (ND1),cytochrome b (Cytb),cytochrome C oxidase subunit I (COXI),and adenosine triphosphatase 6 (ATPase6) in the core subunits of mitochondrial respiratory chain complexes Ⅰ,Ⅲ,Ⅳ,and Ⅴ,respectively. Results Compared with the control group,excess oxygen supply for 1,2,3,and 4 h down-regulated the mRNA levels of ND1 (q=24.800,P<0.001;q=13.650,P<0.001;q=9.869,P<0.001;q=20.700,P<0.001),COXI (q=16.750,P<0.001;q=10.120,P<0.001;q=8.476,P<0.001;q=14.060,P<0.001),and ATPase6 (q=22.770,P<0.001;q=15.540,P<0.001;q=12.870,P<0.001;q=18.160,P<0.001).Moreover,excess oxygen supply for 1 h and 4 h decreased the ATPase activity (q=9.435,P<0.001;q=11.230,P<0.001) and ATP content (q=5.615,P=0.007;q=5.029,P=0.005).The excess oxygen supply for 2 h and 3 h did not cause significant changes in ATPase activity (q=0.156,P=0.914;q=3.197,P=0.116) and ATP content (q=0.859,P=0.557;q=1.273,P=0.652).There was no significant difference in mitochondrial membrane potential among the groups (F=0.303,P=0.869). Conclusion Short-term excess oxygen supply down-regulates the expression of the core subunits of mitochondrial respiratory chain complexes and reduces the activity of ATPase,leading to the energy metabolism disorder of alveolar epithelial type Ⅱ cells.

Comparison of different sedatives in children before general anaesthesia for selective surgery: A network meta-analysis.

WHAT IS KNOWN AND OBJECTIVE: It is estimated that 60% of children undergoing anaesthesia develop severe preoperative anxiety. The anxiety is associated with adverse reactions. Sedatives such as dexmedetomidine, midazolam, clonidine, ketamine, and melatonin can be used as premedication against preoperative anxiety. However, no consensus has been reached on the choice of pre-anaesthetic sedatives in children before selective surgery. Therefore, the current network meta-analysis (NMA) was carried out to evaluate different sedatives in children aged between 1 and 7 before general anaesthesia for selective surgery. METHODS: Randomized clinical trials (RCTs) were retrieved from Pubmed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science databases from inception to October 22, 2021. Primary outcomes showed satisfactory sedation at parent separation and also at induction or mask acceptance. Secondary outcomes were those related to added benefits and side effects. The present NMA was conducted using the R software. Results of the study were reported as Relative Risk (RR) or Mean Difference (MD) at a 95% credible intervals (CrIs). RESULTS AND DISCUSSION: A total of 48 trials were included in the present study. It was found that the effectiveness of dexmedetomidine, midazolam, clonidine, and ketamine were superior to that of placebo in satisfactory sedation at parent separation and induction or mask acceptance. There was no significant difference between melatonin and placebo in satisfactory sedation at induction or mask acceptance. Dexmedetomidine, ketamine, clonidine, and melatonin were superior to placebo in reducing emergence delirium (ED). In addition, midazolam prolonged the length of stay in the post anaesthesia care unit (PACU) as compared with placebo. Dexmedetomidine caused a significant reduction in systolic blood pressure (SBP) and heart rate (HR). Nevertheless, it was noted that the hemodynamic changes were roughly within safety limits. WHAT IS NEW AND CONCLUSION: It was evident that the studied drugs can provide effective sedation with exception of melatonin and placebo. However, it was found that midazolam, ketamine, and clonidine lead to several side effects. The findings of the present study supported that dexmedetomidine, especially intranasal administration, has potential in the optimal selection of the sedatives for premedication in children. This is because the drug has effective sedation, reduced incidence of ED, side effects, and onset time.

Mating-Type Genes Play an Important Role in Fruiting Body Development in Morchella sextelata.

True morels (Morchella spp.) are edible mushrooms that are commercially important worldwide due to their rich nutrition and unique appearance. In recent years, outdoor cultivation has been achieved and expanded on a large scale in China. However, the mechanisms of fruiting body development in morels are poorly understood. In this study, the role of mating-type genes in fruiting body development was researched. Fruiting bodies cultivated with different mating-type strains showed no difference in appearance, but the ascus and ascospores were slightly malformed in fruiting bodies obtained from the MAT1-1 strains. The transcript levels of mating-type genes and their target genes revealed that the regulatory mechanisms were conserved in ascomycetes fungi. The silencing of mat1-2-1 by RNA interference verified the direct regulatory effect of mat1-2-1 on its target genes at the asexual stage. When cultivated with the spawn of single mating-type strains of MAT1-1 or MAT1-2, only one corresponding mating-type gene was detected in the mycelial and conidial samples, but both mat1-1-1 and mat1-2-1 were detected in the samples of primordium, pileus, and stipe. An understanding of the mating-type genes' role in fruiting body development in M. sextelata may help to understand the life cycle and facilitate artificial cultivation.

A comparison of mood, quality of life and executive function among narcolepsy type 1 patients with or without ADHD symptoms in China.

OBJECTIVE: To investigate the prevalence of core attention-deficit/hyperactivity disorder (ADHD) symptoms in Chinese narcolepsy type 1 (NT1) patients and to explore mood, quality of life, and executive function in narcolepsy patients with or without ADHD and the response to Methylphenidate Hydrochloride Extended-release tablets (ER-MPH) treatment. METHOD: A total of 267 pediatric NT1 patients (194 males and 73 females, 5-17 years old) were evaluated for ADHD symptoms by a psychiatrist using the DSM-IV diagnostic criteria of the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI Kid) from February 2011 to July 2013 at Peking University People's Hospital. All patients underwent Stanford Sleep Inventory (SSI) evaluation and polysomnography followed by multiple sleep latency tests (MSLT) before ER-MPH treatment. Neuropsychological evaluations, including the Inventory of Subjective Life Quality (ISLQ), Depression Self-resting Scale for Children (DSRS-C), Screening for Child Anxiety-related Emotional Disorders (SCARED) and Barratt Impulsiveness Scale (BIS), were performed before and after 16 weeks of ER-MPH treatment. Executive abilities were assessed by the Behavior Rating Inventory of Executive Function-parent version (BRIEF-P). The narcolepsy symptoms, evaluated by the Pediatric Sleep Questionnaire (PSQ), and ADHD symptoms were assessed before and after treatment in NT1 patients with ADHD. RESULT: Seventy-seven of 267 (28.8%) NT1 patients had ADHD symptoms, with 73 patients being inattentive type (ADHD-I) and 4 patients being combined type (ADHD-C). Despite similar objective sleep parameters, NT1 patients with ADHD symptoms experienced higher anxiety levels, more impulsive behaviors, lower health-related quality of life and worse executive functions than those without ADHD (p<0.05). Methylphenidate treatment was effective in improving daytime sleepiness in NT1 patients with ADHD (PSQ, 16.7 ± 2.1 vs 13.5 ± 1.9, p<0.05) but was ineffective on ADHD symptoms (ADHD-RS, 25.3 ± 9.1 vs 26.4 ± 8.9, p>0.05). CONCLUSION: A high prevalence of ADHD (28.8%) was identified in children and adolescents with NT1. Comorbid ADHD symptoms were associated with increased levels of mood disorders and lower quality of life. ER-MPH treatment could reduce daytime sleepiness but not ADHD symptoms in narcolepsy patients with ADHD, suggesting that new treatment strategies are needed for this group of patients.

The fate of co-existent cadmium and arsenic during Fe(II)-induced transformation of As(V)/Cd(II)-bearing ferrihydrite.

Ubiquitous co-existence of arsenic (As) and cadmium (Cd) in smelting operations and mine drainage presents a major challenge to the environment. Fe(II)-induced ferrihydrite transformation into secondary, more crystalline minerals often controls the geochemical behavior of associated contaminants including arsenate (As(V)) and Cd(II) in natural and contaminated environments. However, the fate of co-existent As(V) and Cd(II) and the underlying mechanism during this transformation process remain unclear. In this contribution, ferrihydrite containing co-precipitated Cd(II) and As(V) with Fe(II) under diverse pH conditions has been investigated. Results from powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), and Raman spectra show that the co-existence of As(V) and Cd(II) significantly retards the transformation rates of As(V)/Cd(II)-bearing ferrihydrite to more stable iron oxides and reduces that from the newly formed lepidocrocite to goethite. Compared to Cd(II), the co-existent As(V) has stronger influence on the compositions of the transformation products. Chemical analysis shows that phosphate-unextractable As(V) and 0.4 M HCl unextractable Cd(II) both increase as the reaction proceeds during the recrystallization of As(V)/Cd(II)-bearing ferrihydrite, indicating that both As(V) and Cd(II) partially transform to a more stable phase. The co-existent Cd(II) has negligible effects on the As(V) redistribution, but the co-existent As(V) at high loadings has a significant modification in the distribution of Cd(II) during the transformation, which reduces the liberation of Cd(II) into solution, thus decreasing the mobility of Cd(II). These findings have important implications for understanding the mobility and fate of the co-existent As(V) and Cd(II) under natural anoxic environments, remediating the co-existent contaminants, and predicting the long-term behavior of As(V) and Cd(II) in natural and contaminated environments.

TTK predicts triple positive breast cancer prognosis and regulates tumor proliferation and invasion.

This study was conducted to investigate the expression of the spindle assembly checkpoint kinase tyrosine/threonine kinase (TTK) in triple positive breast cancer (TPBC) and its effect on TPBC cells. We analyzed the status of TTK in 69 TPBC samples using immunohistochemistry. The correlation between TTK and clinicopathological parameters was analyzed using a chi-squared test. The prognostic value of TTK was evaluated using Kaplan-Meier survival curves. We analyzed the role of TTK in the invasion and proliferation of TPBC cells in vitro and in vivo. The mean age of the 69 patients with TPBC enrolled in this study was 53 years (range: 29-86 years). TTK expression was positively correlated with tumor size (p=0.034), p53 status (p=0.023), TNM stage ([p=0.023), and Ki-67 index (p<0.001). The Kaplan-Meier curves revealed that TTK expression was correlated with poor disease-free survival (p=0.001) and overall survival (p=0.050). Multivariate proportional hazard regression analyses showed that TTK and TNM staging were significant independent predictors of disease-free survival (p=0.007 and p=0.034, respectively). Additionally, TTK knockdown inhibited the invasion and proliferation of the BT474 TPBC cell line. The findings of this study indicate that TTK overexpression is associated with cancer progression and prognosis in patients with TPBC, whereas TTK knockdown inhibits the invasion and proliferation of TPBC cells. Thus, TTK might serve as a prognostic marker for TPBC.

The Role of Ophiopogonin D in Atherosclerosis: Impact on Lipid Metabolism and Gut Microbiota.

Gut microbiota has been proven to play an important role in many metabolic diseases and cardiovascular disease, particularly atherosclerosis. Ophiopogonin D (OPD), one of the effective compounds in Ophiopogon japonicus, is considered beneficial to metabolic syndrome and cardiovascular diseases. In this study, we have illuminated the effect of OPD in ApoE knockout (ApoE[Formula: see text] mice on the development of atherosclerosis and gut microbiota. To investigate the potential ability of OPD to alleviate atherosclerosis, 24 eight-week-old male ApoE[Formula: see text] mice (C57BL/6 background) were fed a high-fat diet (HFD) for 12 weeks, and 8 male C57BL/6 mice were fed a normal diet, serving as the control group. ApoE[Formula: see text] mice were randomly divided into the model group, OPD group, and simvastatin group ([Formula: see text]= 8). After treatment for 12 consecutive weeks, the results showed that OPD treatment significantly decreased the plaque formation and levels of serum lipid compared with those in the model group. In addition, OPD improved oral glucose tolerance and insulin resistance as well as reducing hepatocyte steatosis. Further analysis revealed that OPD might attenuate atherosclerosis through inhibiting mTOR phosphorylation and the consequent lipid metabolism signaling pathways mediated by SREBP1 and SCD1 in vivo and in vitro. Furthermore, OPD treatment led to significant structural changes in gut microbiota and fecal metabolites in HFD-fed mice and reduced the relative abundance of Erysipelotrichaceae genera associated with cholesterol metabolism. Collectively, these findings illustrate that OPD could significantly protect against atherosclerosis, which might be associated with the moderation of lipid metabolism and alterations in gut microbiota composition and fecal metabolites.

Daporinad in vitro metabolite profiling via rat, dog, monkey and human liver microsomes by liquid chromatography/quadrupole-orbitrap mass spectrometry.

RATIONALE: Daporinad is a novel and potent inhibitor of nicotinamide phosphoribosyl transferase with potential antineoplastic and antiangiogenic activities. We aimed to explore the metabolites of daporinad generated from liver microsomes and to propose metabolic pathways. METHODS: The metabolites were generated by individually incubating daporinad (10 µM) with liver microsomes at 37°C for 60 min. The metabolites were identified by ultra-high-performance liquid chromatography/quadrupole-orbitrap mass spectrometry (UPLC/Q-Orbitrap-MS) using electrospray ionization in positive ion mode. They were deduced by accurate MS and MS/MS data. RESULTS: In total, 16 metabolites were found and their identities were characterized. In rat, dog and human, they were minor; in monkey, M11 was the most abundant. Daporinad was metabolized mainly through N-dealkylation, amide hydrolysis, hydrogenation, oxygenation and dehydrogenation. There was no human-specific metabolite. CONCLUSIONS: The current study provided an overview of the metabolism of daporinad, which is helpful in predicting in vivo metabolites and in selecting animal species for toxicology studies.

Assessment of patient experiences following total sacrectomy for primary malignant sacral tumors: A qualitative study.

BACKGROUND AND OBJECTIVES: Few reports have investigated patient experiences following total en bloc sacrectomy. The aims of this study were to obtain a deeper understanding of patients' personal experiences, needs, and satisfaction with the treatment to reveal areas in which perioperative and long-term patient care can be improved. METHODS: A qualitative design was applied to examine patient experiences and supportive care needs. Patients treated between 2007 and 2017 were identified from our institutional database. RESULTS: A total of 28 survivors were interviewed (13 females, age 13-75 years). Eight themes were identified: the effect of surgery on patients' (a) daily lives, (b) social activities, (c) work or school activities, (d) and family lives; (e) acceptance of ostomy surgery; (f) need for guidance regarding long-term rehabilitation; (g) satisfaction with the medical services provided in the hospital; and (h) satisfaction with the treatment outcomes. CONCLUSION: Total en bloc sacrectomy can yield satisfactory oncological outcomes; however, the procedure is a life-changing event for patients and their families. Physicians must provide long-term support and guidance after surgery to enable patients to fully understand and cope with the changes in their lives.

Modulatory effect of International Standard Scalp Acupuncture on brain activation in the elderly as revealed by resting-state fMRI.

The specific mechanisms by which acupuncture affects the central nervous system are unclear. In the International Standard Scalp Acupuncture system, acupuncture needles are applied at the middle line of the vertex, anterior parietal-temporal oblique line, and the posterior parietal-temporal oblique line. We conducted a single-arm prospective clinical trial in which seven healthy elderly volunteers (three men and four women; 50-70 years old) received International Standard Scalp Acupuncture at MS5 (the mid-sagittal line between Baihui (DU20) and Qianding (DU21)), the left MS6 (line joining Sishencong (EX-HN1) and Xuanli (GB6)), and the left MS7 (line joining DU20 and Qubin (GB7)). After acupuncture, resting-state functional magnetic resonance imaging demonstrated changes in the fractional amplitude of low frequency fluctuations and regional homogeneity in various areas, showing remarkable enhancement of regional homogeneity in the bilateral anterior cingulate, left medial frontal gyrus, supramarginal gyrus, right middle frontal gyrus, and inferior frontal gyrus. Functional connectivity based on a seed region at the right middle frontal gyrus (42, 51, 9) decreased at the bilateral medial superior frontal gyrus. Our data preliminarily indicates that the international standard scalp acupuncture in healthy elderly participants specifcally enhances the correlation between the brain regions involved in cognition and implementation of the brain network regulation system and the surrounding adjacent brain regions. The study was approved by the Ethics Committee of the China-Japan Union Hospital at Jilin University, China, on July 18, 2016 (approval No. 2016ks043).

Long-term acupuncture treatment has a multi-targeting regulation on multiple brain regions in rats with Alzheimer's disease: a positron emission tomography study.

The acute effect of acupuncture on Alzheimer's disease, i.e., on brain activation during treatment, has been reported. However, the effect of long-term acupuncture on brain activation in Alzheimer's disease is unclear. Therefore, in this study, we performed long-term needling at Zusanli (ST36) or a sham point (1.5 mm lateral to ST36) in a rat Alzheimer's disease model, for 30 minutes, once per day, for 30 days. The rats underwent 18F-fluorodeoxyglucose positron emission tomography scanning. Positron emission tomography images were processed with SPM2. The brain areas activated after needling at ST36 included the left hippocampus, the left orbital cortex, the left infralimbic cortex, the left olfactory cortex, the left cerebellum and the left pons. In the sham-point group, the activated regions were similar to those in the ST36 group. However, the ST36 group showed greater activation in the cerebellum and pons than the sham-point group. These findings suggest that long-term acupuncture treatment has targeted regulatory effects on multiple brain regions in rats with Alzheimer's disease.

TIEG1 Represses Smad7-Mediated Activation of TGF-ß1/Smad Signaling in Keloid Pathogenesis.

Transforming growth factor-ß (TGF-ß)/Smad signaling plays a key role in excessive fibrosis and keloid formations. Smad7 is a negative feedback regulator that prevents activation of TGF-ß/Smad signaling. However, the regulatory mechanism for Smad7 in the keloid pathogenic process remains elusive. Here, we show that expression of TIEG1 is markedly higher in keloid fibroblasts, whereas protein, mRNA, and promoter activity levels of Smad7 are decreased. When TIEG1 was knocked down with small interfering RNA, both the promoter activity and protein expression of Smad7 were increased, whereas collagen production and the proliferation, migration, and invasion of keloid fibroblasts were decreased. In contrast, TIEG1 overexpression led to a decrease in Smad7 expression and Smad7 promoter activity. Upon TGF-ß1 stimulation, TIEG1 promoted Smad2 phosphorylation by down-regulating Smad7. Luciferase reporter assays and chromatin immunoprecipitation assays further showed that TIEG1 can directly bind a GC-box/Sp1 site located between nucleotides -1392 and -1382 in the Smad7 promoter to repress Smad7 promoter activity. Taken together, these findings show that TIEG1 is highly expressed in human keloids and that it directly binds and represses Smad7 promoter-mediated activation of TGF-ß/Smad2 signaling, thus providing clues for development of TIEG1 blocking strategies for therapy or prophylaxis of keloids.

Objective: To study the artificial planting technique of Centella asiatica. Methods: The yield and the total content of asiaticoside and madecassoside in C.asiatica were used as evaluating indicators. And the influences of different factors such as soil type, planting density, base fertilizer, fertilization, and shading degree on planting effect were investigated. Results: C.asiatica was suitable to be planted in peat soil/perlite (1∶1), the planting density was 20 cm × 20 cm, the base fertilizer was organic fertilizer/ compound fertilizer (1∶1) and its consumption was 7.5 g/m2, urea (18 g/m2) was applied after 4 months and compound fertilizer (45 g/m2) was applied after 5 months, the appropriate shading degree was 75%. Conclusion: The research results could be used to establish the GAP planting base of C.asiatica.

Rapid Onset of the Effects of Combined Selective Serotonin Reuptake Inhibitors and Electroacupuncture on Primary Depression: A Meta-Analysis.

OBJECTIVES: To evaluate the efficacy and safety of combined selective serotonin reuptake inhibitors (SSRIs) and electroacupuncture therapies for the early treatment of primary depression. METHODS: Randomized controlled trials (RCTs) were analyzed to compare therapy combining SSRIs and electroacupuncture to SSRI therapy alone. The RCTs were identified by searching, among others, PubMed, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Chongqing VIP database for Chinese Technical Periodicals, WANFANG DATA, and the Chinese Biological Medical Literature Database. Scores from Self-Rated Depression Scale (SDS), the Hamilton Depression Scale (HAMD), the Side Effect Rating Scale (SERS), and the Treatment Emergent Symptom Scale (TESS) were analyzed and coded by two independent investigators and used to evaluate the safety and efficacy of treatment. Statistical analyses were performed using RevMan 5.2 software. RESULTS: Six RCTs were analyzed. The meta-analysis revealed that the combined therapy of SSRIs and electroacupuncture were associated with superior scores on the HAMD, SDS, and SERS measures compared with SSRIs alone after 1-4 weeks of treatment: HAMD scores, mean difference (MD)(1 week), 2.32 (95% confidence interval [CI](1 week), 1.47-3.16, p(1 week)<0.00001); MD(2 weeks), 2.65 (95% CI(2 weeks), 1.81- 3.50, p(2 weeks)<0.00001); MD(4 weeks), 2.70 (95% CI(4 weeks), 1.90-3.51, p(4 weeks)<0.00001); SDS scores: MD(1 week), 3.13 (95% CI(1 week), 1.22-5.03, p(1 week) = 0.001); MD(2 weeks), 4.05 (95% CI(2 weeks), 0.22-7.87, p(2 weeks) = 0.04); MD(4 weeks), 5.02 (95% CI(4 weeks), 1.61-8.43, p(4 weeks) = 0.004); SERS scores: MD(2 weeks), 2.20 (95% CI(2 weeks), 1.43-2.96, p(2 weeks)<0.00001); MD(4 weeks), 2.12 (95% CI(4 weeks), 1.42-2.83, p(4 weeks)<0.00001). However, two of the aforementioned outcomes were rated as medium quality because of heterogeneity, as assessed using the Grading of Recommendations Assessment, Development and Evaluation system. CONCLUSIONS: The available evidence suggests that the early treatment of primary depression using both SSRI and electroacupuncture therapies is more efficient than treatments with SSRIs alone and leads to a better and earlier control of depressive symptoms.

Lateralisation of cerebral response to active acupuncture in patients with unilateral ischaemic stroke: an fMRI study.

OBJECTIVE: Acupuncture is beneficial in treating stroke neuropsychiatric symptoms. The present study aimed to identify functional brain response to active acupuncture in patients with unilateral ischaemic stroke using functional MRI (fMRI). METHODS: A total of 10 patients aged 47-65 years with left hemispheric ischaemic stroke received single-session manual acupuncture at the TE5 point of the affected (right) forearm. A 6-min tactile control procedure in which an acupuncture needle tip was alternately touched and removed from the skin at the acupuncture point for 30 s each was performed first, followed by active acupuncture in a blocking paradigm consisting of six 30-s twist blocks of rotation interspersed between six 30-s blocks of rest. A whole brain scan was simultaneously conducted on a 3.0-T imager. Activated and deactivated brain regions during tactile stimulation and active acupuncture relative to rest were obtained via group analysis. RESULTS: Compared to tactile stimulation, needling with twist manipulation modulated many more widespread brain areas. All the brain areas activated and deactivated by active acupuncture relative to tactile stimulation were distributed in the primary sensorimotor and medial frontal cortex of the unaffected, but not the affected hemisphere. CONCLUSIONS: Active acupuncture results in lateralisation of functional cerebral response to the contralateral unaffected hemisphere in patients with unilateral stroke. This lateralisation may represent an effect of acupuncture in enhancing a compensatory process by redistributing functions into the intact cortex, particularly in the unaffected hemisphere.

[Effects of pomegranate flowers polyphenols on liver PON expression of diabetes combining non-alcoholic fat liver diseases rats].

To investigate the protective effects and possible mechanism of pomegranate flowers polyphenols (PFP) on liver function of rats with diabetes combining non-alcoholic fat liver diseases, diabetes combining nonalcoholic fat liver disease model rats were established with high calorie feeding and small dose intraperitoneal injection of streptozotocin (STZ). Model rats were randomly divided into: model group, metformin group, pomegranate flowers polyphenols low, medium and high dose group (75, 150 and 300 mg x kg(-1)). After four weeks treatment, the levels of FPG, blood fat profiles and serum insulin, ALT, AST levels, SOD and MDA in the liver and serum separately were analyzed with biochemical methods. Paraoxonase (PON1 and PON3) mRNA and protein expression in liver were checked by RT-PCR and immunohistochemical method. Pathological changes of the liver were observed. FPG, IRI, non-HDL-C and transaminase significantly reduced and HDL-C raised in the each PFP dose group; Furthermore, compared with model group, fat drops in liver cells significantly reduced, antioxidant ability enhanced, PON1 mRNA and protein expression level in liver increased significantly. The protective effects of PFP against diabetes combining non-alcoholic fat liver diseases rats might through the increase liver PON1 mRNA and protein expression further enhanced the body antioxidant capacity and reduced IRI so as to ameliorate the rat hepatic steatosis.

A 6-week randomized controlled trial with 4-week follow-up of acupuncture combined with paroxetine in patients with major depressive disorder.

Acupuncture possesses the antidepressant potential. In this 6-week randomized controlled trial with 4-week follow-up, 160 patients with major depressive disorder (MDD) were randomly assigned to paroxetine (PRX) alone (n = 48) or combined with 18 sessions of manual acupuncture (MA, n = 54) or electrical acupuncture (EA, n = 58). Treatment outcomes were measured mainly using the 17-item Hamilton Depression Rating Scale (HAMD-17), Self-rating Depression Scale (SDS), clinical response and remission rates. Average PRX dose taken and proportion of patients who required an increased PRX dose due to symptom aggravation were also obtained. Both additional MA and EA produced a significantly greater reduction from baseline in score on HAMD-17 and SDS at most measure points from week 1 through week 6 compared to PRX alone. The clinical response was markedly greater in MA (69.8%) and EA (69.6%) groups than the group treated with PRX alone (41.7%, P = 0.004). The proportion of patients who required an increase dose of PRX due to symptom aggravation was significantly lower with MA (5.7%) and EA (8.9%) than PRX alone (22.9%, P = 0.019). At 4 weeks follow-up after completion of acupuncture treatment, patients with EA, but not MA, continued to show significantly greater clinical improvement. Incidence of adverse events was not different in the three groups. Our study indicates that acupuncture can accelerate the clinical response to selective serotonin reuptake inhibitors (SSRIs) and prevent the aggravation of depression. Electrical acupuncture may have a long-lasting enhancement of the antidepressant effects (Trial Registration: ChiCTR-TRC-08000278).
