虽然高效抗逆转录病毒治疗已经把艾滋病变成了能够长期管理的慢性传染病，可是患者预后的个体差异比较明显。近些年不良环境暴露被发现是影响艾滋病生存质量、免疫重建、疾病进展的重要外源性因素。环境污染物作为广泛存在而且有可预防的外部风险因素，有着低剂量、长时程、多途径暴露的特点，能够通过免疫毒性、氧化应激、慢性炎症激活、代谢紊乱等多种通路，干扰艾滋病患者的免疫重建进程和病毒抑制效果，进而影响其疾病进展、远期生存结局。本文系统综述了大气污染物、重金属、黄曲霉素、多环芳烃等典型环境污染物与艾滋病患者发病进展及预后转归的关联，深入分析人群易感性差异和当前研究存在的局限，可为优化HIV/AIDS患者的健康管理策略、降低环境相关健康风险、改善患者远期预后给予理论参考和实践依据。

Although highly active antiretroviral therapy has turned AIDS into a chronic infectious disease that can be managed for a long time, the individual differences in the prognosis of patients are obvious. In recent years, adverse environmental exposure has been found to be an important exogenous factor affecting the quality of life, immune reconstruction and disease progression of AIDS. As an external risk factor that exists and has potential intervention, environmental pollutants have the characteristics of low-dose, long-term and multi-channel exposure. They can interfere with the immune reconstruction process and virus inhibition effect of AIDS patients through various pathways such as immunotoxicity, oxidative stress, chronic inflammation activation, and metabolic disorders, thereby affecting their disease progression and long-term survival outcomes. This article systematically reviews the association between typical environmental pollutants such as air pollutants, heavy metals, aflatoxins, and polycyclic aromatic hydrocarbons and the progression and prognosis of AIDS patients. In-depth analysis of the differences in population susceptibility and the limitations of current research can provide theoretical reference and practical basis for optimizing the health management strategies of HIV / AIDS patients, reducing environmental-related health risks, and improving the long-term prognosis of patients.

老年人工股骨头置换术后隐性失血是影响手术的重要因素之一,手术后机体生理、病理的变化是一个较为复杂的过程。目前中医对其病因病机尚无系统研究。临床中常存在辨证思维局限,难以客观、全面揭示该病病因病机的特点,进而导致遣方用药难以把握。该文旨在对老年人工股骨头置换术后隐性失血的病因病机进行探讨,认为该病的证候特点为气血亏虚兼瘀,病性为本虚标实,病位肝脾肾,其中气血亏虚贯穿疾病始终,而气为关键。

Hidden blood loss after artificial femoral head replacement in the elderly is one of the important factors affecting the operation,and the change of physiology and pathology after operation is a complicated process．At present,there is no systematic study on its etiology and pathogenesis in traditional Chinese medicine．In clinical practice,there are limitations of dialectical thinking,which make it difficult to Objective ly and comprehensively reveal the characteristics of the etiology and pathogenesis of the disease,and difficult to prescribe．The purpose of this paper is to explore the etiology and pathogenesis of hidden blood loss after artificial femoral head replacement in the elderly．It is considered that the syndrome of the disease is characterized by deficiency of qi and blood and blood stasis,and the disease is based on deficiency of liver,spleen and kidney,in which deficiency of qi and blood runs through the disease all the time,and qi is the key．

代谢综合征属于中医学“肥胖”“消渴”“脾瘅”等范畴,是以多种代谢异常在同一个体集结出现,包括肥胖、高血糖、血脂异常、高血压以及高尿酸血症等为表现的临床综合征。“浊毒”是由于脏腑功能失常,导致机体产生的生理、病理产物不能及时排出,蕴积体内而化生的致病因素。浊毒致病机体多有面色晦浊、腹胀满、小便浑浊、大便黏腻不爽、黄腻苔、滑数脉等表现。浊毒与代谢综合征的发病机制,在微观和宏观上具有对应性。文章从浊毒与代谢综合征的发病机制出发,对其临床治疗的共同点进行了综述。

Metabolic syndrome falls into the categories of obesity,diabetes and spleen disease in traditional Chinese medicine,and is manifested by various metabolic abnormalities in an individual,including obesity,hyperglycemia,dyslipidemia,hypertension and hyperuricemia. The turbid toxin is a pathogenic factor caused by visceral dysfunction,which leads to the accumulation of physiological and pathological wastes that fail to be eliminated from the body in time. People with turbid toxin are manifested by dull and cloudy complexion,abdominal distension,turbid urine,sticky stool,yellow greasy coating,slippery pulse,etc. The turbid toxin corresponds to the pathogenesis of metabolic syndrome at both micro and macro levels. This paper intends to explore the correlations between the turbid toxin and the pathogenesis of metabolic syndrome and make a review with relevant clinical treatment.

目的 探讨黏附因子E-钙粘蛋白(E-cadherin)和Toll样受体9(TLR9)在系统性红斑狼疮(SLE)发病机制中的作用。方法 随机选取SLE患者41例,健康对照组18例,采用酶联免疫吸附试验(ELISA)法检测血清中sE-cadherin的表达,采用流式细胞技术(FCM)检测外周血单核细胞上TLR9的表达。分析 sE-cadherin,TLR9与系统性红斑狼疮患者病情的活动性。结果 SLE组血清中sE-cadherin的表达水平高于正常组(P=0.00),差异有统计学意义;SLE活动组血清中sE-cadherin表达水平高于稳定组(P=0.06),但差异无统计学意义;SLE组TLR9表达高于健康组(P=0.00),活动组高于稳定期组(P=0.00),差异均有统计学意义;SLE患者TLR9表达与SLEDI呈正相关(r=0.727,P=0.00),差异有统计学意义。结论 血清中sE-cadherin和外周血单核细胞内TLR9均参与了SLE患者病情发展的过程,并且二者在SLE发病机制中可能具有协调作用。

Objective To explore the effect of adhesion molecule E-cadherin and Toll-like receptor-9(TLR9) in the pathogenesis of systemic lupus erythematosus(SLE). Methods 41 patients with SLE and 18 healthy controls were selected randomly.Expression of TLR9 in peripheral blood mononuclear cells determined by FCM. SE-cadherin levels were measured in the serum by ELISA analysis. The correlation between sE-cadherin、TLR9 and the patient's condition of SLE was analyzed. Results Compared with healthy subjects,the expression of sE-cadherin in serum was higher among SLE patients(P=0.00),there was statistically significant between two groups;activity group was higher than inactivity group and healthy controls(P=0.06),but there was no statistically significant between activity group and inactivity group. Compared with healthy subjects,the expression of TLR9 in peripherql blood mononuclear cells was higher among SLE patients(P=0.00);activity group was higher than inactivity group(P=0.00),there was all statistically significant between two groups.The positive correlation was observed between TLR9 expression levels and clinical measure of the SLEDAI(r=0.727,P=0.00),there was statistically significant between two groups. Conclusion SE-cadherin and TLR9 may play an important role in SLE,and may interact with each other which needed further study.

Pulmonary hypertension is a kind of low incidence, but it is often caused by right heart failure and other serious pulmonary vascular disease. The main pathological changes of pulmonary vascular include remodeling and pulmonary vascular contraction, and many kinds of cytokines are involved in the pathogenesis of disease, which is the key to improve the prognosis of the disease.
