Objective To analyze trend changes of disease burden of hypertensive nephropathy (HTN) between 2012 and 2023 in Chongqing, and to provide the suggestion for HTN prevention and treatment. Methods Death cases of HTN from Chongqing death registration data between 2012 and 2023 were analyzed to calculate indicators such as mortality, age standardization mortality rate (ASMR), rate of years of life lost (YLL) and Average years of life lost. The mortality of HTN between male and female, urban and rural were compared by Chi-square test. The trend change was explained by average annual percent of change (AAPC). Results The mortality and standardized mortality of HTN in Chongqing decreased from 5.44/100 000 and 3.13/100 000 in 2012 to 2.76/100 000 and 1.07/100,000 in 2023 respectively. The average annual percent change (AAPC) was -5.41% and -8.35% respectively, and the differences in the change trends were statistically significant (P<0.01). The mortality and standardized mortality of HTN in males and females decreased with AAPC of 5.50%, 8.07%, 5.27% and 8.69% respectively, and the differences in the change trends were all statistically significant (all P< 0.05). From 2012 to 2014, 2019 and 2021, the mortality rate of HTN in rural areas was higher than that in urban areas (all P < 0.05). The mortality and standardized mortality of HTN in rural areas decreased with AAPC of 6.58% and 9.46% respectively, and the differences in the change trends were all statistically significant (all P<0.05). The rate of YLL and standardized YLL of HTN in Chongqing decreased from 96.02/100 000 and 60.42/100 000 in 2012 to 44.98/100 000 and 21.49/100 000 in 2023 respectively. The AAPC was -5.83% and -7.80% respectively, and the differences in the change trends were statistically significant (both P < 0.05). AYLL of HTN were 17.88 years in 2012, and it was 17.08 years in 2023. There were no statistically significant differences in the changes (both P > 0.05). The standardized AYLL of HTN in rural areas increased at an average annual rate of 1.14%, and the difference was statistically significant (P < 0.05). Conclusion The mortality and YLL rate of HNT in Chongqing was lower than it in China. Moreover, its trend was decreased. It should be strengthened early screening and healthy management of HNT.

Hereditary hemochromatosis is a rare autosomal genetic disorder that can cause multi-organ dysfunction in the liver,pancreas,spleen,heart and pituitary gland,with diverse clinical manifestations,make the diagnosis difficult.In recent years,with the deepening of clinical understanding and the development of genetic diagnosis tools,the diagnostic rate of this disease has increased significantly.In this paper,we report a case of hereditary hemochromatosis type 3 involving multiple organs and complicated by severe heart failure,aiming to improve the clinicians'understanding of this disease and reduce the leakage and misdiagnosis.

Literature research on ancient books of traditional Chinese medicine （TCM） is an important carrier for inheriting the academic achievements and thoughts of TCM， and a key step for continuing the Chinese civilization and realizing the great rejuvenation of the Chinese nation. Based on this， the paper puts forward the purpose of sorting out TCM ancient books：to explore the treasure of traditional culture， reveal its significance， carry forward its spirit， learn from its experiences， so as to make a contribution to the development of TCM. And this paper expounds several major problems in the literature research， that is， paying attention to the phenomenon of "stubborn bass"， avoiding the trend of "latecomers turning inferior"， attaching importance to the hidden trouble of "making comments on behalf of the ancients". Then， this paper discusses the methodology of carrying out accurate research and revealing the true nature and true value of scholarship with the idea of confucian orthodoxy， the rules of not forgetting the original intention and the scientific method. Taking the materia medica archaeology as an example， the author shared the practical exploration of how to crack the historical code with scientific and technological means， so as to provide useful reference for the literature research on TCM ancient books.

Objective:To explore the efficacy and mechanism of Danggui Shaoyaosan on rats of nonalcoholic fatty liver disease （NAFLD）. Method:Sixrty SPF SD male rats were randomly divided into normal group， model group，essentiale （0.144 g·kg^-1） and low， middle and high-dose of Danggui Shaoyaosan groups （2.44， 4.88， 9.76 g·kg^-1）. High fat diet were fed to bulid the NAFLD model， and each treatment group was given corresponding drugs at the same time. After 8 weeks， the serum and liver tissue were collected to detect the contents or activities of total cholesterol （TC）， triglyceride （TG）， alanine aminotransferase （ALT）， aspartic acid aminotransferase （AST）， tumor necrosis factor-α （TNF-α） and interleukin-10 （IL-10） in serum， the contents of TC， TG and free fatty acid （FFA） in liver tissue， Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） and Western blot were used to observe the gene and protein expressions of Toll-like receptor 4 （TLR4）， myeloid different factory 88 （MyD88） and c-Jun n-terminal kinase （JNK） and the protein expression of phosphorylation JNK（p-JNK） in liver tissue. Hematoxylin-eosin （HE） staining and Oil red staining to observe the pathological morphological changes of liver. Result:Compared with control group， the contents or activities of TC， TG， ALT， AST and TNF-α in serum， the contents of TC， TG and FFA in liver and the gene and protein expressions of TLR4， MyD88， JNK， and the protein expression of p-JNK in liver tissue of model group were distinctly increased （P<0.01）， the content of IL-10 was significantly decreased （P<0.01）. Compared with model group， the contents or activities of TC， TG， ALT， AST and TNF-α in serum， the contents of TC， TG and FFA in liver and the mRNA and protein expressions of TLR4， MyD88 and JNK， and the protein expression of p-JNK in liver tissue of Danggui Shaoyaosan groups were significantly reduced （P<0.05，P<0.01）， the content of IL-10 in serum of Danggui Shaoyaosan groups was distinctly increased（P<0.05，P<0.01）， HE staining and Oil red staining show that the degree of liver steatosis was alleviated obviously by Danggui Shaoyaosan. Conclusion:Danggui Shaoyaosan has a better treatment on NAFLD by inhibiting TLR4/MyD88/JNK pathway and alleviating the inflammation response.

Objective:To observe Plantaginis Semen's mechanism in treating diarrhea by observing the effect on inflammatory factors in serum and mRNA and protein expressions of aquaporin4 (AQP4) in colon tissue of diarrhea rats. Method:Senne Folium was orally administered to duplicate diarrhea rats. Sixty male SD rats were randomly divided into normal group, model group, hydrochlorothiazide group (9 mg·kg^-1), and low, middle, and high-dose Plantaginis Semen groups (0.95, 1.9, 3.8 g·kg^-1). Senne Folium (20 mL·kg^-1) was intragastrically administered in 5 groups in the morning, except for normal group that was orally given the same dose of distilled water. In the afternoon, each treatment group was orally given the corresponding drugs, while normal group and model group were orally given the same dose of distilled water. The loose stool rate, average degree of loose stool, and diarrhea index were compared according to fecal traits and stool times after 14 days of treatment. The serum and colon tissue were collected to detect the contents of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) in serum. Hematoxylin-eosin (HE) staining was used to observe the pathological morphological changes of colon tissue, and quantiative Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the mRNA and protein expressions of AQP4 in colon tissue. Result:In the model group, the loose stool rate, average degree of loose stool, and diarrhea index were significantly increased (P<0.01), apoptosis and necrosis were observed in the epidermal cells of colonic mucosa, telangiectasia and congestion in lamina propria were obvious, and a few neutrophils were infiltrated, and the contents of TNF-α, IL-6 and CRP in serum increased (P<0.05, P<0.01), the mRNA and protein expressions of AQP4 significantly decreased (P<0.01). Compared with the model group, the loose stool rate, average degree of loose stool, and diarrhea index were significantly decreased in low, middle, and high-dose Plantaginis Semen groups (P<0.01), the apoptosis and necrosis of epidermal cells, telangiectasia and hyperemia and neutrophil infiltration in colonic mucosa were obviously improved, and the contents of TNF-α and CRP in serum significantly decreased (P<0.05, P<0.01), the mRNA and protein expressions of AQP4 increased （P<0.05, P<0.01）. Conclusion:Plantaginis Semen has a better antidiarrheal effect, and its mechanism may be related to inhibition of inflammatory reaction, repair of pathological damage of colonic mucosa, up-regulation of AQP4 expression and promotion of water and fluid metabolism.
