Potential Role of Probiotics in Ameliorating Psoriasis by Modulating Gut Microbiota in Imiquimod-Induced Psoriasis-Like Mice

Psoriasis is an immune-mediated systemic disease that may be treated with probiotics. In this study, probiotic strains that could or could not decrease interleukin (IL)-17 levels were applied to imiquimod (IMQ)-induced psoriasis-like mice via oral administration. Bifidobacterium adolescentis CCFM667, B. breve CCFM1078, Lacticaseibacillus paracasei CCFM1074, and Limosilactobacillus reuteri CCFM1132 ameliorated psoriasis-like pathological characteristics and suppressed the release of IL-23/T helper cell 17 (Th17) axis-related inflammatory cytokines, whereas B. animalis CCFM1148, L. paracasei CCFM1147, and L. reuteri CCFM1040 neither alleviated the pathological characteristics nor reduced the levels of inflammatory cytokines. All effective strains increased the contents of short-chain fatty acids, which were negatively correlated with the levels of inflammatory cytokines. By performing 16S rRNA gene sequencing, the diversity of gut microbiota in psoriasis-like mice was found to decrease, but all effective strains made some specific changes to the composition of gut microbiota compared to the ineffective strains. Furthermore, except for B. breve CCFM1078, all other effective strains decreased the abundance of the family Rikenellaceae, which was positively correlated with psoriasis-like pathological characteristics and was negatively correlated with propionate levels. These findings demonstrated effects of strain-specificity, and how probiotics ameliorated psoriasis and provide new possibilities for the treatment of psoriasis.     

Comparison of Three Screening Methods for Sarcopenia in Community-Dwelling Older Persons

ObjectiveThe 2019 Asian Working Group on Sarcopenia in Older People (AWGS 2019) recommends using either calf circumference or the strength, assistance in walking, rising from a chair, climbing stairs, and falls (SARC-F) or SARC-F combined with calf circumference (SARC-CalF) questionnaires for sarcopenia screening. The aim of this study was to compare the ability and applicability of calf circumference, SARC-F, and SARC-CalF for screening sarcopenia among community-dwelling older adults.DesignCross-sectional study.Setting and ParticipantsA total of 1050 community-dwelling older people were enrolled.MethodsSarcopenia was diagnosed according to the AWGS 2019 criteria: bioimpedance analysis for appendicular skeletal muscle index, hand grip, and 6-m gait speed test. Participants also completed the SARC-F questionnaire and calf circumference measurement. The screening tools’ performances were evaluated through receiver operating characteristic (ROC) curves, area under the ROC curves (AUC), and sensitivity/specificity analyses.ResultsSarcopenia was identified in 263 (25.0%) participants by the AWGS 2019 criteria. Calf circumference had a sensitivity of 81.4% and a specificity of 77.0%. Sensitivity and specificity of SARC-F for screening sarcopenia were 17.9% and 93.7%, respectively. SARC-CalF improved the sensitivity of SARC-F (47.5%) while keeping similar specificity (92.0%). The AUCs of calf circumference, SARC-F, and SARC-CalF were 0.79 [95% confidence interval (CI), 0.77–0.82], 0.56 (95% CI, 0.52–0.59), and 0.70 (95% CI, 0.67–0.73), respectively. The differences across ROC curves were statistically significant among 3 screening tools (P < .001).Conclusions and ImplicationsThe overall screening ability of calf circumference was better than that of SARC-F and SARC-CalF for sarcopenia in community-dwelling older persons despite gender, age, and cognitive function. SARC-F and SARC-CalF have high specificity but are susceptible to the preceding factors.     

产褥期乳腺炎影响因素分析

目的探讨导致产妇发生产褥期乳腺炎(PM)的影响因素。 方法选择2020年9月1日至12月31日,在成都市某三甲妇女儿童医院分娩,并进行产后42 d随访的1 162例产妇为研究对象。根据产妇产后42 d内是否发生PM,将其分为PM组(n＝103)与对照组(n＝1 059)。采用本研究自行设计的《产褥期乳腺炎相关影响因素调查问卷》(以下简称为《调查问卷》),联合《中国简式心理状态剖面图(POMS)量表》(以下简称为《POMS量表》),分别对2组产妇进行调查。《调查问卷》内容主要包括产妇一般人口学资料、妊娠及疾病、药物使用、母乳喂养、饮食及生活习惯等10个维度,共计50个条目。《POMS量表》包括心理焦虑等7个维度,共计40个条目。对2组产妇《调查问卷》条目及《POMS量表》评分,采用独立样本t检验、χ²检验及Fisher确切概率法等进行统计学比较。本研究遵循的程序符合病例收集医院医学伦理委员会要求,经过该伦理委员会批准[审批文号：科研伦审2021(29)],并与研究对象签署临床研究知情同意书。2组产妇的年龄等一般临床资料比较,差异无统计学意义(P>0.05)。 结果①本研究纳入产妇的PM发生率为8.9%(103/1 162),产后第3、4周PM发生率最高,分别为2.7%(31/1 162)与2.4%(28/1 162)。②本研究2组产妇围生期补充铁剂及口服益生菌占比,乳头皲裂程度、吸奶器使用时间及频率、乳头保护罩与乳头保护霜使用频率构成比,哺乳衔接姿势正确率,哺乳时乳房疼痛程度、哺乳内衣穿戴率等分别比较,差异均有统计学意义(P<0.05)。③PM组产妇《POMS量表》焦虑评分为(7.1±5.0)分,显著高于对照组的(5.3±4.1)分,并且差异有统计学意义(t＝-3.540、P＝0.001)。④将上述影响产妇发生PM的单因素分析中差异有统计学意义因素,并结合已有研究结果与临床经验,纳入10项影响因素,进行多因素非条件logistic回归分析结果显示,产妇围生期补充铁剂(OR＝3.351,95%CI：1.949~5.758,P<0.001),乳头皲裂(OR＝3.564,95%CI：1.909~6.654,P<0.001),吸奶器使用频率>1次/d(OR＝5.102,95%CI：1.047~24.876,P＝0.044),乳头保护霜使用频率>1次/d(OR＝2.147,95%CI：1.156~3.987,P＝0.016),哺乳衔接姿势不正确(OR＝2.311,95%CI：1.202~4.445,P＝0.012),穿戴不舒适哺乳内衣(OR＝2.322,95%CI：1.008~5.347,P＝0.048),不穿戴哺乳内衣(OR＝3.516,95%CI：1.821~6.789,P<0.001),焦虑评分高(OR＝1.073,95%CI：1.007~1.143,P＝0.029),均为导致产妇发生PM的独立危险因素;而围生期口服益生菌(OR＝0.110,95%CI：0.025~0.478,P＝0.003)是其独立保护因素。 结论通过制定临床干预措施,指导产褥期产妇纠正不正确行为,如围生期补充铁剂、吸奶器与乳头保护霜使用不当,哺乳内衣穿戴及哺乳行为不规范等,提倡产妇围生期口服益生菌,缓解产妇焦虑情绪,对预防产妇PM发生具有重要意义。     

Estimate of Burden and Direct Healthcare Cost of Infectious Waterborne Disease in the United States

Provision of safe drinking water in the United States is a great public health achievement. However, new waterborne disease challenges have emerged (e.g., aging infrastructure, chlorine-tolerant and biofilm-related pathogens, increased recreational water use). Comprehensive estimates of the health burden for all water exposure routes (ingestion, contact, inhalation) and sources (drinking, recreational, environmental) are needed. We estimated total illnesses, emergency department (ED) visits, hospitalizations, deaths, and direct healthcare costs for 17 waterborne infectious diseases. About 7.15 million waterborne illnesses occur annually (95% credible interval [CrI] 3.88 million–12.0 million), results in 601,000 ED visits (95% CrI 364,000–866,000), 118,000 hospitalizations (95% CrI 86,800–150,000), and 6,630 deaths (95% CrI 4,520–8,870) and incurring US $3.33 billion (95% CrI 1.37 billion–8.77 billion) in direct healthcare costs. Otitis externa and norovirus infection were the most common illnesses. Most hospitalizations and deaths were caused by biofilm-associated pathogens (nontuberculous mycobacteria, Pseudomonas, Legionella), costing US $2.39 billion annually.

Relationship between liver fibrosis criteria and syndrome-type of TCM in patients with non-alcoholic fatty liver

To explore the relationship between the liver fibrosis criteria and TCM Syndrome type in patients suffering from non-alcoholic fatty liver. Methods: Seventy-nine patients with non-alcoholic fatty liver diagnosed by B ultrasonography were classified by TCM Syndrome Differentiation and their liver fibrosis criteria was determined and compared with those of the healthy subjects as control. Results: Levels of procollagen Ⅲ (PCⅢ), hyaluronic acid (HA), collagen Ⅳ(CⅣ) and laminin (LN) in the fatty liver group were significantly higher than those in the control group (P＜0.05, P＜0.01). In respect to the TCM Syndrome-types, PCⅢ, CⅣ and LN in patients of Phlegm-stasis combined type were significantly higher than those in patients of Spleen deficiency-Phlegm dampness Syndrome-type and Damp-Heat Syndrome-type (P＜0.05, P＜0.01), while HA in different groups was insignificantly different (P＞0.05). Conclusion: There was trend of liver fibrosis in fatty liver patients. It was indicated that the Phlegm-stasis combined Syndrome-type possibly was the main TCM pathologic factor of the increasing of fibrosis criteria for non-alcoholic fatty liver.

Clinical observation on effect of shuanghuang shengbai granule on chemotherapy induced myelpsuppression in tumor patients and on ultrastructure of bone marrow in mice

To observe the leucocyte increasing effect of Shuanghuang Shengbai Granule (SHSBG) in tumor patients treated by chemotherapy and the bone marrow microenvironment protecting effect in mice.

Methods  

Patients of non-small-cell pulmonary, mammary, gastric or intestinal cancer, who were ready for receiving re-treatment of chemotherapy, were enrolled and divided into 4 groups randomly. The 28 cases in SHSBG group A received chemotherapy combined with SHSBG; the 27 in the SHSBG group B received chemotherapy alone at first, and SHSBG was added when their peripheral white blood cell (WBC) count lowered to <4×10⁹/L; the 33 in control group A and 24 in control group B were treated by the method similar to that applied to SHSBG group A and B respectively but with Rubidate instead of SHSBG. Experimental study of electron microscopic observation on bone marrow ultrastructure in mice was also conducted.
