Rapid and living guidelines are those developed in response to public health emergencies in a short period of time using a scientific and standardized approach. Subsequently, they provide timely and credible recommendations for decision makers through regular and frequent updates of clinical evidence and recommendations. In this paper, we introduced the definition of rapid and living guideline as well as analyzed the basic characteristics of eight rapid and living guidelines in the field of traditional Chinese medicine (TCM) published till 2023 June, summarizing three core methodological issues in relation to how to rapidly develop guidelines, how to formulate recommendations when there is lack of evidence, and how to ensure the timeliness of guidelines. Based on the analysis of current rapid and living guidelines, it is implicated that there is necessity to carry out rapid and living guideline in the field of TCM, and the methodology of rapid integration of multivariate evidence in the field of TCM needs to be further explored; furthermore, it is necessary to further explore the obstacles of implementation of guidelines and promote timely updating, all of which provide certain theoretical references for relevant guideline developers and researchers.

It is necessary to develop rapid and living guidelines in order to improve the evidence translation and guidance for clinical practice in emergency situations, and to enhance the participation of traditional Chinese medicine (TCM) in management of emergencies. This paper introduced the process of developing rapid and living guidelines of TCM and divided it into three stages, that is preparation, rapid development and dynamic updating, which highlights the features of rapid development, high quality, and dynamic updating and the integration with the predominance of TCM. By comparing with general guidelines on composition, personnel number, timing to formulate and communication patterns of the guideline working groups, as well as the content and number of clinical questions, this paper mainly gave suggestions on how to formulate a concise but authoritative team during the preparation stage, how to efficiently manage the guideline team and promote the development process from conflict of interest management, working and communication mode adjustment, and how to formulate and update the important and prioritized clinical questions, all of which may provide reference for the development of TCM rapid and living guidelines.

The lack of direct evidence is an important problem faced in the formation of recommendations in rapid living guidelines of traditional Chinese medicine under public health emergencies, and the supplementation of indirect evidence can be a key method to solve this problem. For the collection of evidence, the type of evidence required, including direct and indirect evidence, should be clarified, and ‘direct first’ principle for selecting evidence can be set to standardize and accelerate the guideline development. When integrating evidence, recommendations can be formed directly if there is sufficient direct evidence, while regarding insufficient direct evidence, recommendations need to be supplemented and improved by integrating indirect evidence. In addition, when the body of evidence contains evidence from multiple sources, it is suggested to rate the evidence according to “higher rather than lower” principle. Finally, when forming recommendations, the level of evidence, safety and economic efficiency should be taken into consideration to determine the strength of the recommendation.

In developing rapid and living guidelines of traditional Chinese medicine (TCM) in response to public health emergencies, it is important that evidence continue to be reviewed, and clinical questions and recommendations updated if necessary, due to the rapid changes in disease progression and the continuous generation of relevant research evidence. This paper proposed that the updating scope in dynamic mode should first be identified; then evidence monitoring should be carried out in four aspects, including clinical research, related guidelines or laws and regulations, disease progression, as well as clinical use of recommendations and clinical needs; finally, based on the results of the evidence monitoring, different options should be made, including revising the clinical questions, updating the evidence and recommendations, and withdrawing the guideline.

Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.

The aim of this study was to prepare tandem multimeric proteins of BmSPI38, a silkworm protease inhibitor, with better structural homogeneity, higher activity and stronger antifungal ability by protein engineering. The tandem multimeric proteins of BmSPI38 were prepared by prokaryotic expression technology. The effects of tandem multimerization on the structural homogeneity, inhibitory activity and antifungal ability of BmSPI38 were explored by in-gel activity staining of protease inhibitor, protease inhibition assays and fungal growth inhibition experiments. Activity staining showed that the tandem expression based on the peptide flexible linker greatly improved the structural homogeneity of BmSPI38 protein. Protease inhibition experiments showed that the tandem trimerization and tetramerization based on the linker improved the inhibitory ability of BmSPI38 to microbial proteases. Conidial germination assays showed that His6-SPI38L-tetramer had stronger inhibition on conidial germination of Beauveria bassiana than that of His6-SPI38-monomer. Fungal growth inhibition assay showed that the inhibitory ability of BmSPI38 against Saccharomyces cerevisiae and Candida albicans could be enhanced by tandem multimerization. The present study successfully achieved the heterologous active expression of the silkworm protease inhibitor BmSPI38 in Escherichia coli, and confirmed that the structural homogeneity and antifungal ability of BmSPI38 could be enhanced by tandem multimerization. This study provides important theoretical basis and new strategies for cultivating antifungal transgenic silkworm. Moreover, it may promote the exogenous production of BmSPI38 and its application in the medical field.

9.Research progress of Hedgehog signaling pathway inhibitors in anti-tumor field
China Pharmacy 2023;34(8):1014-1019
Hedgehog (Hh) signaling pathway plays an important regulatory role in the process of cell proliferation, differentiation and tissue formation. Proper intensity and action time of Hh signal are crucial for the normal development of various tissues of the body, and its abnormal activation will lead to the occurrence and development of most malignant tumors, including breast cancer, liver cancer, pancreatic cancer, and lung cancer, which makes Hh signaling pathway an ideal target for anti-tumor drug research and development. At present, the main targets of Hh signaling pathway inhibitors include Hh ligand, receptor Smoothened (Smo) and transcription factor Gli. Among them, the compounds that depend on the Hh ligand pathway still remain at the stage of laboratory research because they cannot act on the non-classical Hh signaling pathway. The special structure of Smo protein enables it to combine with drugs efficiently and selectively, which is a powerful and effective drug target. Therefore, Smo selective inhibitors have been an active field of related research, and many Smo inhibitors have entered the clinical use or trial stage. Gli can regulate multiple carcinogenic genes, promote abnormal cell proliferation and lead to tumor, and can also cause feedback inhibition to Hh signaling pathway. Therefore, the development of drugs that can inhibit the activity of Gli has broad prospects. In the future, a combination of multiple pathway inhibitors can be designed to avoid drug resistance and other side effects.

OBJECTIVES:
To investigate the reliability and accuracy of deep learning technology in automatic sex estimation using the 3D reconstructed images of the computed tomography (CT) from the Chinese Han population.
METHODS:
The pelvic CT images of 700 individuals (350 males and 350 females) of the Chinese Han population aged 20 to 85 years were collected and reconstructed into 3D virtual skeletal models. The feature region images of the medial aspect of the ischiopubic ramus (MIPR) were intercepted. The Inception v4 was adopted as the image recognition model, and two methods of initial learning and transfer learning were used for training. Eighty percent of the individuals' images were randomly selected as the training and validation dataset, and the remaining were used as the test dataset. The left and right sides of the MIPR images were trained separately and combinedly. Subsequently, the models' performance was evaluated by overall accuracy, female accuracy, male accuracy, etc.
RESULTS:
When both sides of the MIPR images were trained separately with initial learning, the overall accuracy of the right model was 95.7%, the female accuracy and male accuracy were both 95.7%; the overall accuracy of the left model was 92.1%, the female accuracy was 88.6% and the male accuracy was 95.7%. When the left and right MIPR images were combined to train with initial learning, the overall accuracy of the model was 94.6%, the female accuracy was 92.1% and the male accuracy was 97.1%. When the left and right MIPR images were combined to train with transfer learning, the model achieved an overall accuracy of 95.7%, and the female and male accuracies were both 95.7%.
CONCLUSIONS
The use of deep learning model of Inception v4 and transfer learning algorithm to construct a sex estimation model for pelvic MIPR images of Chinese Han population has high accuracy and well generalizability in human remains, which can effectively estimate the sex in adults.
