By analyzing medical painting artworks from ancient and modern times， both in China and abroad， this paper explored the visual narrative functions and their historical evolution. The study revealed that in ancient times， medical painting art was mostly set against religious and mythological backgrounds， portraying the mysterious and supernatural aspects of disease. With the advent of the Renaissance， painting art gradually broke free from religious constraints and began to depict disease more realistically. In modern times， painting art has further embodied humanistic care and ethical spirit， and has gradually integrated narrative therapy and health communication， reflecting the integration of medical science and humanistic spirit. This evolutionary process not only witnessed the development of medical science and the transformation of human health concepts but also revealed the changes in the narrative characteristics of medical painting art from obscurity to clarity， from metaphor to concreteness， and from a one-sided focus on biological aspects to an emphasis on medical， social， and humanistic aspects.

【Objective】 To investigate the frequency of platelet antibodies in voluntary blood donors and patients in Zhongshan, Guangdong Province, and to study the specificity and cross-matching of platelet antibodies. 【Methods】 Platelet antibodies of blood donors and patients were screened by solid-phase immunoadsorption (SPIA), rechecked by flow cytometry (FCM), and antibody specificity was identified by PakPlus enzyme immunoassay, and platelet cross-matching was simulated by SPIA. 【Results】 A total of 1 049 blood donor samples and 598 patient samples were tested, with 6 (0.57%) and 49 (8.19%) samples positive for SPIA,respectively(P<0.05); In SPIA positive samples, the positive concordance rate of FCM in blood donors and patients was 100% vs 95%, and that of enzyme immunoassay was 100% vs 88%. Among the initial screening positive samples of blood donors, 5 were anti-HLA Ⅰ antibodies, accounting for 83%, and 1 was anti CD36 antibody, accounting for 17%, with an incidence rate of 0.10%. Among the 14 samples of enzyme immunoassay positive patients, 2 were anti-GP Ⅱb/Ⅲa, 1 was anti-GP Ⅱa/Ⅱa, 8 were anti HLA Ⅰ, and 3 were mixed antibodies (HLA Ⅰ, GP Ⅱb/Ⅲa, GP Ⅰa/Ⅱa). According to the types of antibodies, HLA Ⅰ antibodies were the most common, accounting for 65% (11/17), followed by HPA related anti GP, accounting for 35% (6/17). The majority of patients had a platelet antibody positive typing rate below 30%, accounting for 71.4% (10/14). 【Conclusions】 The positive rate of platelet antibody of patients in Zhongshan area is significantly higher than that of voluntary blood donors, and most of them are anti-HLA Ⅰ and anti-GP, and the incidence of anti-CD36 is extremely low. Therefore, it is necessary to establish a known platelet antigen donor bank, and at the same time, carry out platelet antibody testing and matching of patients, which is helpful to solve the issue of platelet transfusion refractoriness.

Aquaporins (AQPs) are water channel proteins that facilitate the transport of water molecules across cell membranes. To date, seven AQPs have been found to be expressed in mammal kidneys. The cellular localization and regulation of the transport properties of AQPs in the kidney have been widely investigated. Autophagy is known as a highly conserved lysosomal pathway, which degrades cytoplasmic components. Through basal autophagy, kidney cells maintain their functions and structure. As a part of the adaptive responses of the kidney, autophagy may be altered in response to stress conditions. Recent studies revealed that autophagic degradation of AQP2 in the kidney collecting ducts leads to impaired urine concentration in animal models with polyuria. Therefore, the modulation of autophagy could be a therapeutic approach to treat water balance disorders. However, as autophagy is either protective or deleterious, it is crucial to establish an optimal condition and therapeutic window where autophagy induction or inhibition could yield beneficial effects. Further studies are needed to understand both the regulation of autophagy and the interaction between AQPs and autophagy in the kidneys in renal diseases, including nephrogenic diabetes insipidus.

【Objective】 To investigate the frequency of CD36 deletion and gene mutation in voluntary blood donors of Zhongshan city, and to explore the possibility of establishing local CD36 negative platelet donor bank. 【Methods】 Platelet CD36 antigen was detected by ELISA in 1 654 voluntary blood donors.Some of the negative samples were confirmed by flow cytometry, and genotyping was also performed. 【Results】 Platelet CD36 antigen was negative in 27 cases, accounting for 1.6% (27/1654), among which 1.6% (18/1149) were males and 1.8% (9/505) were females.No significant difference was noticed between males and females in CD36 antigen deletion cases (P>0.05). Fifteen CD36 negative samples were randomly selected, genotyped and sequenced, with type I deletion in 1 case[ 6.7% (1/15)], type Ⅱ deletion in 14 cases[ 93.3% (14/15)], and gene mutation in exon 3-14 detected in 8 cases. 【Conclusion】 The frequency of platelet CD36 antigen deletion in Zhongshan is comparable to that in other southern regions of China.The establishment of CD36 negative platelet donor bank is conductive to improve the effectiveness of platelet transfusion.

【Objective】 To understand the frequency and significance of anti-" Mi^a" (anti-" Mi^a" mixtures of antibodies) in local population in Zhongshan, and the influence of different experimental conditions on the activity of human anti-" Mi^a" . 【Methods】 The microplate-based agglutination assay and polybrene method were used to screen anti-" Mi^a" in 3 587 blood samples from voluntary blood donors and patients using O type red blood cells with positive Mi^a antigen, then.rechecked by tube method and microcolumn gel card method. 【Results】 The frequency of anti-" Mi^a" was 1.06% (38/3 587), among which 60.5% (23/38) were IgM and 39.5% (15/38) were mixture of IgM and IgG; 0.61% (13/2 135) in local blood donors and 1.72% (25/1 452) in patients(P<0.01). 65.8% (25/38) of the population carrying anti-" Mi^a" had a history of immunity. 57.9% (22/38) were identified to be anti-" Mur" and 42.1% (16/38) anti-" Mi^a" using GP.Vw erythrocyte. The appropriate incubation time for anti-" Mi^a" test was 10 min. 【Conclusion】 The frequency of anti-" Mi^a" was relatively high among blood donors and patients in Zhongshan, and most of the anti-" Mi^a" carriers had a history of immunity. Most anti-Mi^a antibodies were active in saline, and some of them were mixture of IgM and IgG. It may be helpful to include Mi^a positive red blood cells in the irregular antibody screening cell panel to improve the safety of blood transfusion.

Objective To explore the effectiveness of the fallopian tubes embolization for the hydrosalpinx before in vitro fertilization and embryo transfer(IVF-ET).Methods The fallopian tubes embolization was performed on 46 hydrosalpinx patients-Fimt the hysterosalpingography was performed to show the positions and shape of the hydrosalpinx.Then the hydrops was drawn into the celiac cavity in order to be absorbed after performing fallopian tube recanalization. Finally,transv(o)ihal therapy was performed,putting the embolization microcoils into the fallopian tube through a micro-catheter.One month after the fallopian tubes embolization,hystemsalpingography was conducted to check for the effectiveness of the embolization.After 3 months.all the 46 patients received the treatment of IVF-ET,Results The interventional treatment of 82 fallopian tubes obtained one time success among 46 cases of fallopian tubes embolization.Among them,obvious results were achieved in 72 fallopian tubes,taking up 88%0f tIle total;effective results were seen in 10 fallopian tubes.accounting for 12%0f the total.No one was invalid.In the same period,compared with the 91 cases of non-hydrosalpinx as the control group.the embolization group of patients achieved a higher fertilization rate(69%),and clinical pregnancy rate(41%),compared with the control group(63%and 39%respectively),but without a significant difference(P>0.05).However,the ectopic pregnancy rate(O)and the abortion rate(8%)were significantly lower than the control group(8%,16%respectively;P<0.05).Conclusions Fallopian tubes embolization used in hydrosalpinx treatment before IVF-ET is an innovative approach,simple,safe,economical,with no negative impact on ovarian functiorr It can significantly increase the clinical pregnancy rate and prevent the occurrence of tubal pregnancy.It is a feasible and effective method.
