Brain organoid-on-chip platforms have emerged as groundbreaking tools in neural disease modeling and drug discovery, offering a unique and highly accurate simulation of human organ physiology and function compared with traditional cell culture systems. This technology is a harmonious fusion of organ-on-a-chip and organoid culture technologies, leveraging their strengths to provide the most realistic in vitro replication of the in vivo environment, both physically and biologically. As both technologies continue to advance rapidly, this platform is highly promising in vitro platform for disease modeling. In this review, we summarize the historical developments, recent advancements, limitations, and future prospects of brain organoid-on-chip technology, aiming to illuminate the transformative potential of this platform in advancing our understanding and treatment of neural diseases.

Objective To explore the feasibility and effectiveness of otoacoustic emission (OAE) in hearing screening for preschool children .Methods A total of 616 preschool children aged 3～6 (mean age 4 .6 years old) were included in this study .All the subjects received transiently evoked otoacoustic emission (TEOAE) test by trained personnel .The children who failed the hearing screening received diagnostic examination in the hearing ex-amination center .Results Of 616 children ,66 (10 .71％ ) failed the hearing screening and 16 children received audi-ological assessment .In these 16 children ,8 had otitis media with effusion (5 with mild conductive hearing loss ) ,5 had impacted cerumen ,3 had normal hearing ,and none had sensorineural hearing loss .Conclusion OAE can be used effectively in the hearing screening for preschool children .But how to improve the referral rate of children who failed the hearing screening needs further discussion .

Objective To observe the clinical effect of auricular bean-burying therapy in acupoints for patients with hepatocellular carcinoma after interventional therapy.Methods A total of 48 patients with hepatocellular carcinoma were divided into control group and observation group.The control group received western conventional nursing.The observation group applied auricular seeds.Pain scores and sleep quality were compared between two groups.Results The intervention group had lower painscores and quality of sleep at 2,3 and 7 d after intervention had lower than the control group (P ＜ 0.05).Conclusion Auricular bean-burying therapy in acupoints can effectively improve postoperative pain,and improve sleep quality for patients with hepatocellular carcinoma after interventional therapy.

Objective To investigate the effects of Baduanjin exercise on the fatigue and quality of life in patients with moderate inflammatory bowel disease (IBD).Methods Totally 63 moderate IBD patients who were treated via the IBD diagnosis and treatment platform Nanjing Hospital of Chinese Medicine between March and July 2017 and met the inclusion criteria were selected and randomly divided into the control group (n=31) and the observation group (n=32) according to the random number table. Patients in the control group received general guidance for anti-fatigue via the WeChat platform on the basis of conventional medication, while patients in the observation group did Baduanjin exercise in addition to general guidance and medication. The fatigue and quality of life scores were compared between the two groups.Results The observation group scored lower on the whole and in the dimensions of general fatigue, physiological fatigue, less physical activities and mental fatigue than the control group after intervention (t=6.403, 6.746, 4.440, 3.409, 3.893;P< 0.05); but there was no significant difference in the dimension of lower enthusiasm between the two groups (t=0.486,P>0.05). In terms of the quality of life, the observation group scored higher on the whole and in the dimensions of bowel symptoms and general symptoms (t=-2.045, -2.254, -6.870;P<0.05); but there was no significance in the dimensions of emotional function and social function between the two groups (t= -0.041, 0.257;P>0.05).Conclusions Baduanjin exercise in traditional Chinese medicine can alleviate the fatigue symptoms in moderate IBD patients and improve their quality of life.

Aim To investigate the effect of Ding''s herb enema prescription on intestinal tissue related target in rat colitis induced by dextran sulfate sodium(DSS), and to elucidate the mechanism of Ding''s herb enema prescription in improving the intestinal inflammation and intestinal fibrosis.Methods Rats were fed with 3.5％ DSS.The rats were randomly divided into positive drug group, model group, Control group, and Ding''s herb enema prescription group.The positive drug group was treated with mesalazine enema, and Ding''s herb enema prescription group was treated with Ding''s herb enema prescription.The colon mucosa was taken once a day for 6 weeks.The changes of intestinal inflammatory response and intestinal fibrosis related proteins were detected by GSR-CAA-67 antibody protein array, and the differentially expressed proteins were screened out.Results Eight proteins showed statistical differences, including IFN-γ, erythropoietin(EPO), TIMP-2, TIM-1, IL-6, TIMP-1, TNF-α, IL-22 (P<0.05).On the other hand, Ding''s herb enema prescription and mesalazine significantly antagonized the effect of IL-6 and TIMP-1 (P<0.05).The antagonized effect of Ding''s embolization enema on TNF-α and IL-22 was also significant(P<0.05), but mesalazine had no similar effect (P>0.05).Conclusions Ding''s herb enema prescription has the effect of multiple targets, which may improve the intestinal inflammatory response and intestinal fibrosis to achieve the purpose of treatment of ulcerative colitis(UC).

Objective To establish multiple short tandem repeat (STR) amplification by fluorescence labeling polymerase chain reaction (PCR) for monitoring the effect of allogeneic hematopoietic stem cell transplantation .Methods Sixty‐five patients were analyzed .DNA from peripheral blood of donors and recipients in pre transplantation and post transplantation were extracted , 15 STR loci and sexual loci were amplified by PCR .Results After allo‐HSCT ,54 patients obtained type of donors ,but 3 patients did not ;eight patients showed mixed chimerism .Two cases of type of donor converted into mixed chimerism and two cases of mixed chimerism converted into type of donors after some time .The time of earliest detection ,duration and transformation of each state was different .The earliest detection showed on the 16th day after surgery ,and the last one showed five months later .As to the du‐ration ,the shortest and longest were two months and seven months ,respectively .Conclusion The key factors that significantly in‐fluence the application of STR‐PCR in monitoring the effect of allogeneic hematopoietic stem cell transplantation were samples ,STR loci and proper monitoring time .So to establish the suitable method for this region could truly take maximum advantage of the PCR‐STR method .While a appropriate detecting time and STR loci should be chose .
