RESUMEN
As an important element of medical and health sector innovation, the translation of scientific and technological achievements plays a key role in promoting their clinical application and meeting the medical needs of the people. The authors sorted out the problems in such translation at these affiliated hospitals in terms of " people", " finance", " material", and " system". Starting from 2017, the Tenth People′s Hospital Affiliated to Tongji University has explored such practices as establishing hospital-led clinical medical science and technology innovation parks and technology service limited companies. These practices aimed to address the issues of insufficient hospital scientific and technological innovation capabilities and the gap between the hospital′s operation mechanism to translate its scientific and technological achievements and the enterprises and the market. The clinical medical science and technology innovation park integrating administration, industry, education, research, medicine and application, has taken multiple measures to attract excellent research talents and projects from within and beyond the hospital, promote the implementation of innovative scientific research projects. The hospital also established a health industry mode with engagement of social capital from large enterprises. The Technology Services Co., Ltd. was based on the incubation and translation of hospital achievements, combining market and clinical needs, promoting multi-party cooperation between hospitals and external enterprises, improving the chain operation mechanism of hospital scientific and technological achievements translation work, and alleviating the problem of insufficient research pilot funds and productibility funds by means of hospital-led fundraising. The number of patent authorizations of hospitals had increased from 23 cases in 2018 to 105 in 2022, and the amount of patent conversion had increased from 2 million yuan in 2020 to 11 million yuan in 2022. It is recommended that affiliated hospitals of universities further improve the organizational structure of achievement translation, strengthen their professional talent teams, improve their operation mechanism of achievement translation, build a platform for medical school-enterprise cooperation, and improve the evaluation mechanism of translation assessment, in order to promote a virtuous cycle of hospital′s scientific and technological achievement translation work.
RESUMEN
BACKGROUND@#Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA.@*METHODS@#A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease.@*RESULTS@#The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production.@*CONCLUSION@#Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

Objective To explore the clinical and endoscopy features of Mallory-Weiss Syndrome(MWS),and summarize the experience on the diagnosis and treatment of MWS. Methods We retrospectively analyzed the clinical data of cases of MWS. Results Including 11 cases homeostasis by endoscopy 31 cases received conservative treatment except 1 case by surgery. All cases were cured. Conclusion Endoscopy is the first choice of diagnosing MWS. It,s the effective homeostasis measure.
RESUMEN
ATP binding cassette transporter (ABCT),a membrane transporting protein existing in mammalian, bacterial, fungal and many other types of cells, is correlated with multidrug resistance in many cells. To date 10 ABCT have been described in Candida albicans , but only CDR1 and CDR2 genes were associated with multidrug resistance. Moreover, their encoding proteins Cdr1p and Cdr2p have many functions such as efflux pump and phospholipid translocator. The progress in the study of Cdr1p and Cdr2p proteins mediating multidrug resistance in Candida albicans was summarized in the paper.
