The effect of massage therapy on pain after surgery: A comprehensive meta-analysis

BackgroundFindings on the usefulness of massage therapy (MT) in postoperative pain management are often inconsistent among studies.ObjectivesThis study’s aim is to conduct a meta-analysis of randomized controlled trials (RCT) to clarify the effects of massage therapy in the treatment of postoperative pain.MethodsThree databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) were searched for RCTs published from database inception through January 26, 2021. The primary outcome was pain relief. The quality of RCTs was appraised with the Cochrane Collaboration risk of bias tool. The random-effect model was used to calculate the effect sizes and standardized mean difference (SMD) with 95 % confidential intervals (CIs) as a summary effect. The heterogeneity test was conducted through I². Subgroup and sensitivity analyses were used to explore the source of heterogeneity. Possible publication bias was assessed using visual inspection of funnel plot asymmetry.ResultsThe analysis included 33 RCTs and showed that MT is effective in reducing postoperative pain (SMD, −1.32; 95 % CI, −2.01 to −0.63; p = 0.0002; I² = 98.67 %). A similar significant effect was found for both short (immediate assessment) and long terms (assessment performed 4–6 weeks after the MT). Remarkably, we found neither the duration per session nor the dose had an impact on the effect of MT and there seemed to be no difference in the effects of different MT types. In addition, MT seemed to be more effective for adults. Furthermore, MT had better analgesic effects on cesarean section and heart surgery than orthopedic surgery.LimitationsPublication bias is possible due to the inclusion of studies in English only. Additionally, the included studies were extremely heterogeneous. Double-blind research on MT is difficult to implement, and none of the included studies is double-blind. There was some heterogeneity and publication bias in the included studies. In addition, there is no uniform evaluation standard for the operation level of massage practitioners, which may lead to research implementation bias.ConclusionsMT is effective in reducing postoperative pain in both short and long terms.     

Neighborhood resources associated with frailty trajectories over time among community-dwelling older adults in China

Background and objectivesRecent research has identified neighborhoods as an important contributor to later-life frailty. However, little is known about how neighborhood resources are associated with frailty trajectories over time, especially in developing countries. This study examines the impact of neighborhood physical and social resources on the trajectories of frailty over time among older people in China.Research design and methodsUsing the four waves of the China Health and Retirement Longitudinal Study (2011–2018), 5673 respondents aged 60 and above at baseline were included for analyses. Multilevel growth modeling was fitted to estimate the effects of neighborhood resources on frailty trajectories over a 7-year period, controlling for individual-level characteristics.ResultsOlder Chinese people who lived in neighborhoods with better basic infrastructures and a greater number of voluntary organizations were less frail at baseline. Accessible exercise facilities were associated with a lower initial level of frailty only among rural older adults, while higher community-level socioeconomic status (SES) was associated with a lower initial level of frailty only among urban older adults. Over the 7-year follow-up period, better basic infrastructures and accessible exercise facilities were associated with a slower increase rate of frailty scores among rural residents.Discussion and implicationsNeighborhood resources are important contributors to the level of frailty among older Chinese people. Our findings of significant urban-rural differences have important implications for designing and implementing infrastructure development and community building programs in rural and urban China.     

基于免疫机制从“脾虚生痰湿”论治多发性抽动症的研究＊

多发性抽动症的发病率逐年升高，严重影响儿童生长发育及心理健康。中医治疗多发性抽动症（脾虚痰湿型）取得显著效果，但作用机制仍不明确。近年来，诸多研究表明“脾虚生痰湿”和免疫系统之间存在密切关系，还揭示了免疫机制在抽动症发病中起重要作用。本文通过概述多发性抽动症（脾虚痰湿型）的病机与免疫之间的关系，发现多发性抽动症（脾虚痰湿型）患者免疫状态与大脑皮质-基底节-丘脑-皮层回路异常密切相关，细胞免疫损伤参与了多发性抽动症的发生和发展。并分析了健脾化痰祛湿中药治疗多发性抽动症的潜在机制，为从“脾虚生痰湿”论治多发性抽动症提供相关科学依据。     

基于临床观察文本解析痛经辨治规律研究

整体护理联合加速康复外科应用于小儿尿道下裂修复术的效果

目的探讨整体护理联合加速康复外科(ERAS)措施应用于小儿尿道下裂修复术的效果。方法选择2019年3月至2021年5月中山市博爱医院收治的80例尿道下裂修复术的患儿作为研究对象,按照随机数字表法将其分为参照组(40例)与实验组(40例)。参照组采取传统护理方案,实验组采取整体护理联合ERAS,比较两组干预后并发症发生率、满意度及下床活动时间、切口愈合时间、术后首次排便时间、住院时间,使用儿童疼痛评估量表(FLACC)评估患儿疼痛程度。结果实验组并发症总发生率低于参照组,总满意度高于参照组,差异有统计学意义(P<0.05);实验组下床活动时间、切口愈合时间、术后首次排便时间、住院时间均短于参照组,10 d内排便次数低于参照组,差异有统计学意义(P<0.05)。护理前两组FLACC评分比较,差异无统计学意义(P>0.05);两组护理后FLACC评分低于护理前,且护理后实验组FLACC评分低于参照组,差异有统计学意义(P<0.05)。结论在小儿尿道下裂修复术中给予整体护理联合ERAS措施,可促进患儿尽快康复,减轻其疼痛程度,降低并发症发生率,缩短住院时间,提升患儿家属满意度,值得临床借鉴。     

The efficacy of a Persian herbal formulation on functional bloating: A double-blind randomized controlled trial

BackgroundBloating is a common gastrointestinal complaint which is difficult to treat.ObjectiveThis study investigated the efficacy and compliance of a formulation called KAASER comprised of Trachyspermum ammi (L.) Sprague seed, Zingiber officinale Roscoe. rhizome and Piper nigrum L. berry in the treatment of functional bloating.Design, setting, participants and interventionA total of 106 patients with functional bloating, between 20 and 50 years of age, participated in this double-blind randomized controlled trial. Patients were divided into 3 parallel groups that received 500 mg of placebo, dimethicone or KAASER, three times a day for 2 weeks.Main outcome measuresThe frequency and severity of bloating were primary outcomes, while the frequencies of eructation, defecation, borborygmus and early satiation were secondary outcomes. All parameters were evaluated at the beginning (week 0), and also weeks 2, 4 and 10 of the study, through self-report checklists with a scoring system.ResultsAmong the 84 patients who completed the study, the frequency and severity of bloating (P < 0.001), the frequencies of eructation, defecation and borborygmus (P = 0.03) were significantly improved in the group receiving KAASER (36 patients) compared with the dimethicone (35 patients) and placebo (35 patients) groups, during the 3 phases of follow-up. These significant differences persisted through the 2 and 8 weeks of follow-ups after cessation of medication (week 4 and 10). In early satiation, no significant differences were observed among the 3 groups.ConclusionThe results showed that KAASER can be effectively used to treat patients suffering from bloating. Bloating, eructation, defecation and borborygmus in the KAASER group remained significantly improved after 2 and 8 weeks of cessation of medication, making this mechanism an interesting area for further investigation.Trial registrationRegistration trial IRCT2015100324327N on Iranian Registry of Clinical Trials.     

“阳化气，阴成形”：卵巢癌的中医证治

卵巢癌属于妇科恶性肿瘤之一,其发病率逐年上升趋势,属中医的"癥瘕"范畴。秉承《素问》"阳化气,阴成形"之旨来探讨卵巢癌的病机及治疗,认为"阳化气"不足,"阴成形"太过为卵巢癌发病的一个重要原因,并由此提出温补阳气的卵巢癌治疗原则,指出该原则应贯穿整个卵巢癌治疗的始终。
