Research progress on the relationship between air pollution and chronic kidney disease / 公共卫生与预防医学

Objective To explore the relationship between exposure to air pollutants and chronic kidney disease. Methods We searched and screened the literature on air pollutant exposure and CKD, using Pubmed, Medline, Embase, and Cochrane databases from inception to May 1, 2020. Chronic exposure to air pollutants and risk of chronic kidney disease were estimated. Results Air pollutants can cause kidney damage to varying degrees, and PM2.5 and PM10 can increase the risk of chronic kidney disease. CO, NO2(NOX) and SO2 may increase the risk of chronic kidney disease. Conclusions Exposure to air pollutants, especially particulate matter( PM2.5 and PM10) ，is associated with an increased risk of chronic kidney disease.

Analysis ofZhangZhong-jing’s Acupuncture-moxibustion Treatment Characteristics and Academic Thought / 上海针灸杂志

This article sorts out and analyzes acupuncture-moxibustion items inTreatise on Cold Damage DiseasesandSynopsis of Prescriptions of the Golden Chamberand proposes regularities in application of and the characteristic ofZhangZhong-jing’s acupuncture and moxibustion. Acupuncture was often used for unblocking and regulating meridional qi and clearing and purging excessive heat. Moxibustion was often used for warming yang and remedying deficiency or dispersing and unblocking yang qi. Because of convenient operation, acupuncture-moxibustion therapy was often used to treatdangerous and serious diseases. Acupuncture and moxibustion were often combined with herbal prescriptions and other therapeutic methods to improve therapeutic effects, especially on difficult and complicated diseases.ZhangZhong-jing’s guiding thought ofacupuncture-moxibustion treatment first advocates treatment of diseases from the root and meanwhile, pays attention to treatment of both symptoms and causes of diseases. Secondarily, it emphasizes acupuncture-moxibustion treatment based on syndrome differentiation and especially values pulse condition, meridians and acupuncture points. It has abundant contents in treating the same disease with different methods and often selects specific acupoints. Thirdly, it favours preventive treatment of diseases, andwhether prevention of diseases before they arise or prevention of diseases from exacerbating was embodied in his acupuncture-moxibustion treatment.

KRT 9 Gene Mutations in Three Chinese Pedigrees with Epidermolytic Palmoplantar Keratoderma / 中华皮肤科杂志

Objective To investigate the keratin 9 gene mutation in epidermolytic palmoplantar keratoderma (EPPK) and its relationship with clinical manifestations. Methods Three Chinese pedigrees with EPPK were studied. Polymerase chain reaction (PCR) was performed to amplify the seven exons encoded by keratin 9. Denaturing high-performance liquid chromatography (DHPLC), DNA sequencing and allele-specific PCR were used to reveal the sequence variation in the PCR products. Results An insertion-deletion mutation in the exon 1 of keratin 9 497delAinsGGCT, was revealed in all 3 EPPK families, resulting in the keratin 9 change from tyrosine166 to tryptophan and leucine (Y166delinsWL). Allele-specific PCR confirmed that the mutation was not a commonly seen polymorphism, but a novel mutation which has not been reported in The Human Intermediate Filament Mutation Database (http://www.interfil.org). Conclusions A new keratin 9 gene mutation, 497delAinsGGCT, is found in these Chinese EPPK pedigrees, which may be the genetic basis of EPPK.

Relationship between Heart Rate Variability and Cold-Heat/Deficienc y-Excess Syndromes in TCM / 中医杂志

Objective To study the characteristics of heart rate variabili ty (HRV) in states of calm supine position, supine position and counting, and ca lm upstanding position, and the relationship with TCM syndromes of cold-h eat and deficiency-excess. Methods Totally 233 patient s diagnosed by TCM & western medicine with different syndromes were divided into five groups. B y comparing the general changes of frequency domain of HRV under three kinds of condition s, the variation of HRV indexes was measured in the excess heat syndrome group ( 64 cases), deficiency cold syndrome group (16 cases), cold-heat complex syndrom e group (38 cases), yin deficiency with fire syndrome group (67 cases), and defic iency of both yin and yang syndrome group (48 cases). Results The low frequenc y (LF) and low frequency normalized unit (LFNU) manifested sympathetic nervous a ctivity were augmented and were related with the yang syndrome and heat syndrome obvi ously. The high frequency (HF) and high frequency normalized unit (HFNU) manifes ted parasympathetic nervous activity were augmented and were related with the yi n syn drome and cold syndrome. The increased LF/HF reflected the yang syndrome and hea t syndrome. The decreased LF/HF reflected yin syndrome and cold syndrome. The co ndition of counting had a weighing influence on the diagnosis of yang syndrome a nd heat syndrome. And the condition of upstanding played a weighing role in defi ciency syndrome and cold syndrome. Conclusion The law o f changes of HRV under three kinds of condition is helpful in syndrome differentiation of cold-heat an d deficiency-excess.
