Dryness is an important concept in the theory of traditional Chinese medicine， which is closely related to the transformation of the body， etiology and pathogenesis. As one of the medicinal properties of Chinese materia medica， there are various types of Chinese materia medica with dryness. Atractylodis Rhizoma（AR） is a representative medicine with warm and dry properties， which has the function of drying dampness and strengthening the spleen. Due to its strong dryness， it can cause certain adverse reactions. In clinical practice， stir-fried AR with bran is often used as medicine. The dryness of AR is closely related to its efficacy， but the underlying mechanism of the relationship between dryness and efficacy is still unclear. At present， the research on dryness Chinese materia medica has been increasing year by year， but there are still problems such as insufficient systematic research， insufficient in-depth research and lack of research on the mechanism of dryness effect， which limit the breakthrough of the theory of processing for slowing down dryness， and hinder the precise application of dryness Chinese materia medica in clinical practice. Therefore， this article comprehensively reviewed the differences in dryness characterization indicators of different Chinese materia medica by searching domestic and foreign literature， focusing on the relevant research on dryness of AR. A systematic summary and induction were made from the characterization indicators， research techniques of dryness markers， the influence of processing on dryness of AR， and the application mining of dryness of AR. The results showed that the dryness characteristics of AR mainly included the upregulation of macroscopic indicators such as water intake， urine output and whole blood viscosity， as well as energy metabolism indicators， the downregulation of water metabolism indicators， and pathological changes such as submandibular gland acinar atrophy. Based on the changes of dryness and component content of AR after processing， it is determined that the main dryness components of AR may be volatile components such as β-eudesmol and atractylon. Due to its dryness， AR is mainly used to treat diseases such as spleen deficiency， rheumatism and edema. However， the current understanding of the correlation between dryness and efficacy of AR is still insufficient， and there are still many bottlenecks in understanding and explaining its dryness. In the future， systematic evaluation and characterization should be carried out to find the common mechanism of AR exerting dryness and efficacy， providing reference for the rational clinical use.

Objective To study the changes in serum autophagy markers in children with retinopathy of prematurity(ROP)and its clinical value.Methods Premature infants who were screened for ROP in our hospital from January 2020 to December 2022 were selected as the study subjects.Those screened out with ROP at 4-6 weeks of birth were assigned to the ROP group and those without ROP to the control group.The levels of serum autophagy markers LC3-Ⅱ,Beclin-1 and P62 were detected at the 3rd day,1st,2nd and 3rd weeks of birth.The two groups were compared in terms of serum autophagy markers.The diagnostic efficacy of serum autophagy markers on ROP was analyzed.Results There was no significant difference in serum LC3-Ⅱ,Beclin-1 and P62 levels between the ROP group and control group at the 3rd day of birth(P>0.05).At the first,second and third weeks of birth,how-ever,the ROP group showed significantly lower levels of serum LC3-Ⅱ and Beclin-1 but higher level of P62 com-pared to the control group(both P<0.05).The levels of serum LC3-Ⅱ,Beclin-1 and P62 at the first,second and third weeks of birth had diagnostic value for ROP.The children in the ROP group who did not receive mechanical ventilation and oxygen inhalation,and did not develop with sepsis and bronchopulmonary dysplasia showed lower serum LC3-Ⅱ and Beclin-1 levels and higher P62 levels at the first,second and third weeks of birth compared to those without the above-mentioned treatment as well as those complications(all P<0.05).In the ROP group,those with severe ROP showed lower serum LC3-Ⅱ and Beclin-1 levels and higher P62 levels at the 3rd day,and 1st,2nd and 3rd week of birth(all P<0.05).Conclusion The levels of serum autophagy markers in children with ROP show significant changes since the first week of birth,so they have diagnostic efficacy for the diseases.

BACKGROUND:The most prominent transcription factor activated by tumor stem cells in osteosarcoma is EZH2,and silencing of EZH2 has been reported to inhibit osteosarcoma cell growth.Studies have confirmed that bovine serum albumin-chitosan nanoparticles are a drug delivery vector with excellent biocompatibility and biodegradability,and the albumin carrier can provide tumor-targeted drug delivery function. OBJECTIVE:To investigate the effect and mechanism of bovine serum albumin-chitosan nanoparticles loaded with EPZ6438(EZH2 inhibitor)for the treatment of osteosarcoma. METHODS:(1)Bovine serum albumin-chitosan nanoparticles loaded with and without EPZ6438 were prepared.The drug encapsulation rate and drug release rate of serum albumin-chitosan nanoparticles loaded with EPZ6438 were detected.(2)MG-63 cells were divided into four groups and added with PBS(control group),serum albumin-chitosan nanoparticle extract solution(blank nanoparticle group),EPZ6438 solution(free drug group),and serum albumin-chitosan nanoparticle extract loaded with EPZ6438(drug-loaded nanoparticle group),respectively.After 3 days of culture,cell apoptosis was detected by flow cytometry and the expression of caspase-3 mRNA was detected by RT-PCR.(3)Twelve nude mice were selected and the subcutaneous tumor-bearing mouse model was established by injecting MG-63 cell suspension under the armpit.After successful modeling,the mice were randomly divided into four groups for intervention.Normal saline(control group),serum albumin-chitosan nanoparticle solution(blank nanoparticle group),EPZ6438 solution(free drug group)and serum albumin-chitosan nanoparticle solution loaded with EPZ6438(drug-loaded nanoparticle group)were injected into tumor tissues,with three animals in each group.After 7 days of injection,the tumor volume and frozen sections of tumor tissue were observed by TUNEL staining. RESULTS AND CONCLUSION:(1)The drug encapsulation rate of the nanoparticles was about 8.8%,and the nanoparticles had a good drug release effect in pure water.The drug release amount was(34.72±1.93)μg at 24 hours,(48.58±1.10)μg at 72 hours,(49.18±1.24)μg at 120 hours,and(50.25±1.13)μg at 168 hours.The drug release reached the plateau at 120 hours,and the release rate was about 97.9%.(2)After 3 days of cell culture with MG-63,the apoptotic rate in the control group and blank nanoparticle group was lower than that in the free drug group and drug-loaded nanoparticle group(P<0.001),and the expression of caspase 3 mRNA was lower than that in the free drug group and drug-loaded nanoparticle group(P<0.000 1).(3)After 7 days of injection,the tumor volume of nude mice in the drug-loaded nanoparticle group was smaller than that in the other three groups(P<0.05),and the percentage of TUNEL-positive cells in tumor tissue was higher than that in the other three groups(P<0.000 1).(4)The results verify that serum albumin-chitosan nanoparticles loaded with EPZ6438 can inhibit the growth of osteosarcoma by inducing apoptosis of tumor cells.
