2. The pathogenic characteristics and ethnic differences of diabetic retinopathy
Medical Journal of Chinese People's Liberation Army 2020;45(6):663-671
Diabetic retinopathy (DR) is one of the most common microangiopathies of diabetes mellitus (DM). It is due to abnormal blood glucose metabolism caused by insufficient insulin secretion or decreased activity. Its pathogenesis is complex, related to multi-gene inheritance and environmental factors. At present, the etiologic study of DR has been gradually deepened at home and abroad, but the epidemiological study of minority DR is lacking. This paper reviews DR's characteristics, ethnic differences and its characteristics in ethnic minority.

Medium-chain fatty acids (MCFAs) are mostly generated from dietary triglycerides and can penetrate the blood-brain barrier. Astrocytes in the brain use MCFAs as an alternative energy source. In addition, MCFAs have various regulatory and signaling functions in astrocytes. However, it is unclear how astrocytes sense and take up MCFAs. This study demonstrates that decanoic acid (DA; C10), a saturated MCFA and a ligand of G(αs) protein-coupled receptors (G(αs)-GPCRs), is a signaling molecule in energy metabolism in primary astrocytes. cAMP synthesis and lactate release were increased via a putative G(αs)-GPCR and transmembrane adenylyl cyclase upon short-term treatment with DA. By contrast, monoamine oxidase B-dependent gamma-aminobutyric acid (GABA) synthesis was increased in primary cortical and hypothalamic astrocytes upon long-term treatment with DA. Thus, astrocytes respond to DA by synthesizing cAMP and releasing lactate upon short-term treatment, and by synthesizing and releasing GABA upon long-term treatment, similar to reactive astrocytes. Our data suggest that astrocytes in the brain play crucial roles in lipid-sensing via GPCRs and modulate neuronal metabolism or activity by releasing lactate via astrocyte-neuron lactate shuttle or GABA to influence neighboring neurons.

Aim To investigate the effect of Aesculus hippocastanum seed extract(AH) on concanavalin A (ConA)-induced acute liver injury in mice,and to ex-plore whether the mechanism was related to the inhibi-tory effect of AH on oxidative stress and c-Jun N-termi-nal kinase (JNK). Methods ConA(20 mg·kg-1) was administered via tail vein injecting to induce he-patic damage in mice. The groups of AH were given at 12.5,25,50 mg·kg-1by oral gavage separately for 20 days. The serum levels of AST,ALT,TP,and Alb were determined by automatic biochemical analyzer and the A/G ratio was calculated. TNF-α and IFN-γ levels were assayed by ELISA. The liver tissue was attained by HE and the histopathological changes were calculat-ed. The MDA, SOD, GSH contents of liver tissues were assayed by related kits. The activity of caspase-3 was detected by spectrophotometry. The expressions of cytochrome C and Bax, Bcl-2, p-JNK and p-Akt were detected by Western blot. Results The serum levels of ALT, AST, IFN-γ and TNF-α in AH groups were significantly lower than those in ConA-injured group, while the levels of TP,Alb and A/G were significantly higher. The SOD and GSH levels of liver tissues signif-icantly increased and MDA level decreased; liver his-topathological changes were consistent with those of the serological indicators, and AH treatment significantly reduced the pathological damage induced by ConA. In AH group,the expression of cytochrome C,caspase-3, Bax/Bcl-2 ratio and p-JNK markedly decreased, while the expression of p-Akt protein increased compared with ConA model group. Conclusion AH could sig-nificantly protect the ConA-induced acute liver injury in mice via inhibition of ROS and JNK pathway.

Objective To explore the relationship between the volatile components in Angelicae Sinensis Radix from different regions of Gansu Province and its growing environment with metabolomics based on GC-MS. Methods The GC-MS method was used for detecting the volatile components in Angelicae Sinensis Radix from 31 different regions in Gansu province, and principal component analysis (PCA) and partial least squares (PLS) methods were used for analyzing and evaluating its relationship with the growing environment. Results The results of PCA showed that the volatile components in Angelicae Sinensis Radix from different regions in Gansu province were related to the altitude and the soil types. The PLS method could divide 31 samples of Angelicae Sinensis Radix from different regions in Gansu Province into three groups according to the difference of altitude. There were significant differences in the volatile components in the samples taken at different altitude regions. After analyzing linear loading plots from PCA and PLS, 11 charateristic components were screened out, including 7 compounds were identified by the retrieval of NIST11 database. Conclusion The volatile components in Angelicae Sinensis Radix from different regions in Gansu Province are closely related to the altitude and the soil type.

Objective To analyze the injury death status and potential loss due to injury death in monitoring area in shaanxi province from 2015 to 2017, so as to provide a scientific basis for preventing and controlling injury. Methods Descriptive epidemiological method was used to analyze the cause of injury death data. Health economics was used to calculate the potential losses caused by injury death,calculate mortality,standardized death rate,constituent ratio,years of potential life lost(PYLL),average number of years lost(AYLL),working years of potential life lost(WPYLL),average working years of potential life lost(AWPYLL),potential economic lost(PEL). Results The average mortality of injury was 55.76 per 100 000(standardized rate was 45.83 per 100 000) in Shaanxi province from 2015 to 2017.The average injury mortality of male was higher than female,and countryside was higher than city.The leading causes of injury death were traffic accidents,falls,suicide,poisoning. Drowning and homicide were the main types of AYLL,male was higher than female and countryside was high than city.PYLL,WPYLL and PEL in traffic accident were 88 218 person-years,56 413 person-years and 2.728 billions of Yuan,and all of them were higher in male than female, and higher in city than countryside. PYLL,WPYLL and PEL in suicide were 16 789 person-years,10 868 person-years and 0.526 billions of Yuan, higher in female than male, and higher in countryside than city. Conclusions Injury has become a serious public health problem endangering people’s life and health in Shaanxi province,and also the leading cause of death in loss of labor and potential economic loss.

BACKGROUND/AIMS: Fragmented care in nephrology can cause treatment delays. Nephrologists are qualified to perform vascular access-related procedures because they understand the pathophysiology of renal disease and perform physical examination for vascular access. We compared treatment delays associated with tunneled hemodialysis catheter (TDC) placement between interventional radiologists and nephrologists. METHODS: We collected data by radiologists from January 1, 2011 through December 31, 2011 and by nephrologists from since July 1, 2012 through June 30, 2013. We compared the duration from the hemodialysis decision to TDC placement (D-P duration) and hemodialysis initiation (D-H duration), catheter success and the complication rate, and the frequency and the usage time of non-tunneled hemodialysis catheters (NDCs) before TDC placement. RESULTS: The study analyzed 483 placed TDCs: 280 TDCs placed by radiologists and 203 by nephrologists. The D-P durations were 319 minutes (interquartile range [IQR], 180 to 1,057) in the radiologist group and 140 minutes (IQR, 0 to 792) in the nephrologist group. Additionally, the D-H durations were 415 minutes (IQR,260 to 1,091) and 275 minutes (IQR, 123 to 598), respectively. These differences were statistically significant (p = 0.00). The TDC success rate (95.3% vs. 94.5%, respectively; p = 0.32) and complication rate (16.2% vs. 11%, respectively; p = 0.11) did not differ between the groups. The frequency (24.5 vs. 26%, respectively; p = 0.72) and the usage time of NDC (8,451 vs. 8,416 minutes, respectively; p = 0.91) before TDC placement were not statistically significant. CONCLUSIONS: Trained interventional nephrologists could perform TDC placement safely, minimizing treatment delays.
