OBJECTIVE To establish the project approval evaluation system for traditional Chinese medicine （TCM） preparations in medical institutions guided by new drug conversion， to improve the success rate of approval for TCM preparations in medical institutions and lay the foundation for the later drug conversion. METHODS Research and development team used the literature research method and brainstorming method to list and organize relevant elements of project evaluation and determine the initial indicator system. Experts were consulted using the Delphi method to confirm the evaluation index. The weights were calculated based on the proportion of importance scores for each indicator and assigned specific scores to each item. The indicator system was used to evaluate 31 TCM preparations applied for filing by various departments of our hospital from April to July 2023. RESULTS After two rounds of 17 experts’ consultation， the final TCM preparation system included five primary indicators， i.e. theoretical basis， clinical research foundation， pharmaceutical foundation， prescription， and clinical value， as well as 17 secondary indicators including prescription source， traditional Chinese medicine theory， clinical positioning and so on. Human experience was considered as the item which would be rejected as one vote. Based on the above indicator system， our hospital further improved the filing and project approval process for TCM preparations in medical institutions. Among the 31 TCM preparations applied for filing by various departments from April to July 2023， 8 TCM preparations with a score ≥65 were selected for development. CONCLUSIONS The evaluation system is objective， comprehensive， and highly operable. It is suitable for the selection of TCM preparations in medical institutions before research and development.

Objective:To explore the characteristics, clinical manifestations and gene mutation types of Cornelia de Lange syndrome (CdLs), and to improve the understanding of the disease.Methods:Clinical data and gene test results of a pediatric case of CdLs diagnosed in the First Affiliated Hospital of Xinxiang Medical University in August 2019 were analyzed retrospectively.Results:A female patient with 2 years and 8 months old presented a special appearance with a low and flat nose, a wide eye distance, audition ears, a downward inclination of the mouth corner, a high arch of the jaw and a small jaw deformity, who had recurrent seizures, speech and mental retardation.The result of gene test showed the mutation of SMC1A gene c. 2923C > T, and thus the patient was diagnosed as type 2 CdLs. Conclusions:CdLs is a rare genetic metabolic disease with special facial features and physical signs.There is only one case of CdLs with gene mutation of SMC1A in China through literature review.The mutation of SMC1A gene c. 2923C>T in CdLs cases has not been reported at home and abroad, which expands the variation spectrum of the SMC1A gene.

【Objective:】 Using classic moral dilemma cases, this paper investigates the choice tendency of medical students when facing the moral dilemma, and analyzes their cognitive status and characteristics when facing the "moral dilemma", in order to provide effective enlightenment for optimizing the teaching cases of medical ethics. 【 Method:】 771 medical students in Shanghai Jiao Tong University School of Medicine were investigated by electronic questionnaire and SPSS 20.0 for statistical description and statistical analysis. 【Result:】 In the emergency room doctors and transition scenes, medical students tend to the principle of maximum happiness, and in the ring track scene and pedestrian overpass scene, they tend to the principle of deontology; In the loop track scene and pedestrian overpass scene, boys are more inclined to deontological principles than girls, and undergraduates are more inclined to deontological principles than postgraduates, and the difference is statistically significant (P<0.05). 【Conclusion:】 Although medical students have different moral tendencies in different scenes, they generally do not agree with the practice of sacrificing one person to save five people. Especially when more rigorous sacrifice conditions cause greater moral pressure, the vast majority of medical students will tend to the latter between utilitarianism and deontological principles.

Single-cell genomics provides substantial resources for dissecting cellular heterogeneity and cancer evolution. Unfortunately, classical DNA amplification-based methods have low throughput and introduce coverage bias during sample preamplification. We developed a single-cell DNA library preparation method without preamplification in nanolitre scale (scDPN) to address these issues. The method achieved a throughput of up to 1800 cells per run for copy number variation (CNV) detection. Also, our approach demonstrated a lower level of amplification bias and noise than the multiple displacement amplification (MDA) method and showed high sensitivity and accuracy for cell line and tumor tissue evaluation. We used this approach to profile the tumor clones in paired primary and relapsed tumor samples of hepato-cellular carcinoma (HCC). We identified three clonal subpopulations with a multitude of aneuploid alterations across the genome. Furthermore, we observed that a minor clone of the primary tumor containing additional alterations in chro-mosomes 1q, 10q, and 14q developed into the dominant clone in the recurrent tumor, indicating clonal selection during recurrence in HCC. Overall, this approach provides a comprehensive and scalable solution to understand genome hetero-geneity and evolution.

Objective:To investigate the expression and significance of Toll-like receptor 4 (TLR4) in renal tissue and peripheral blood of children with idiopathic nephrotic syndrome(INS).Methods:The renal biopsy tissues of 78 children with INS diagnosed in the First Affiliated Hospital of Xinxiang Medical University from October 2015 to June 2018 and normal renal tissues of 21 children (control group 1) were collected, and the expressions of TLR4 in the renal tissue was detected by using immunohistochemical method.The expression of TLR4 in different renal pathological types and clinical types of INS was compared, and the correlation of TLR4 with 24-hour urinary protein and serum albumin was analyzed.The expression levels of TLR4 in peripheral blood of children with INS before and after treatment (active stage and remission stage) and 23 healthy children (control group 2) were detected by enzyme linked immunosorbent assay(ELISA). The serum expression levels of TLR4 in different renal pathological types and clinical types of INS were compared, and the correlation of TLR4 with 24-hour urinary protein and serum albumin was analyzed; The correlation between TLR4 expression in renal tubules and in the serum of children with INS was also analyzed.Results:(1)Compared with the expression of TLR4 in normal renal tissues[(0.93±0.26)%], the expression of TLR4 in glomeruli and interstitium of all pathological types of INS [mesangial proliferative glomerulonephritis (MsPGN): (0.93 ± 0.21)%, focal segmental glomerulosclerosis (FSGS): (1.02±0.25)%, membranous glomerulonephritis(MN): (1.03±0.09)%, minimal change disease(MCD): (1.02±0.27)%]was not significantly different ( F=0.741, P=0.562), but the expression of TLR4 in renal tubules[MCD: (82.94±4.62)%, MN: (63.54±1.98)%, MsPGN(42.32±2.97)%, FSGS: (22.60±2.07)%] was significantly increased ( F=1 929.842, P<0.01), Especially, the expression of TLR4 in renal tubules of MCD type INS was significantly higher than that of MN, MsPG N and FSGS [MCD: (82.94±4.62)%, MN: (63.54±1.98)%, MsPGN: (42.32±2.97)%, FSGS: (22.60±2.07)%], and the differences were statistically significant(all P<0.01). TLR4 expression in renal tubules was the highest in steroid-sensitive nephrotic syndrome (SSNS) type and the lowest in INS patients with steroid-resistant nephrotic syndrome (SRNS) type, and the differences were statistically significant( F=220.951, P<0.01). (2)The expression of serum TLR4 in INS children at the active stage [MsPNG: (143.36±12.99) ng/L, FSGS(75.94±7.29) ng/L, MN(210.22±14.66) ng/L, MCD(283.93±21.58) ng/L]was significantly higher than that in INS children at remission stage [MsPNG: (29.51±4.93) ng/L, FSGS(15.66±3.78) ng/L, MN(45.40±5.73) ng/L, MCD(62.29±7.90) ng/L]and control group 2[(0.69 ± 0.33) ng/L], and the differences were statistically significant(all P<0.01); the expression of serum TLR4 in INS children at remission stage was significantly higher than that in the control group 2 ( F=286.287, P<0.01). TLR4 had the highest expression level in serum of MCD type INS children at active and remission stages, followed by MN and FSGS successively.The expression of serum TLR4 was highest in SSNS and lowest in SRNS, and the differences were statistically significant ( F=147.438, P<0.01). (3)The expression of TLR4 in renal tubules of children with INS[(62.82 ±20.94)%]was positively correlated with the expression of TLR4 in serum[(213.26±73.33) ng/L] ( r=0.852, P< 0.05). The expression levels of TLR4 in renal tubules and serum of INS patients at active stage were positively correlated with 24-hour urinary protein level[(123.05±33.55) mg/kg] ( r=0.401, 0.427, all P<0.05), and negatively correlated with serum albumin level[(19.54±3.55)g/L] ( r=-0.602, -0.617, all P<0.05). Conclusions:The expression of TLR4 in renal tubules and serum of children with INS increases, and may be related to different renal pathological types and clinical types of children with INS, as well as disease activity.
