Objective To explore the effect of microRNA-22-3p (miR-22-3p) regulating the expression of Kruppel-like factor 6 (KLF6) on the cardiomyocyte-like differentiation of bone marrow mesenchymal stem cell (BMSC). Methods Rat BMSC was isolated and cultured,and the third-generation BMSC was divided into a control group,a 5-azacytidine(5-AZA)group,a mimics-NC group,a miR-22-3p mimics group,a miR-22-3p mimics+pcDNA group,and a miR-22-3p mimics+pcDNA-KLF6 group.Real-time fluorescent quantitative PCR (qRT-PCR) was carried out to determine the expression of miR-22-3p and KLF6 in cells.Immunofluorescence staining was employed to detect the expression of Desmin,cardiac troponin T (cTnT),and connexin 43 (Cx43).Western blotting was employed to determine the protein levels of cTnT,Cx43,Desmin,and KLF6,and flow cytometry to detect the apoptosis of BMSC.The targeting relationship between miR-22-3p and KLF6 was analyzed by dual luciferase reporter gene assay. Results Compared with the control group,5-AZA up-regulated the expression of miR-22-3p (q=7.971,P<0.001),Desmin (q=7.876,P<0.001),cTnT (q=10.272,P<0.001),and Cx43 (q=6.256,P<0.001),increased the apoptosis rate of BMSC (q=12.708,P<0.001),and down-regulated the mRNA (q=20.850,P<0.001) and protein (q=11.080,P<0.001) levels of KLF6.Compared with the 5-AZA group and the mimics-NC group,miR-22-3p mimics up-regulated the expression of miR-22-3p (q=3.591,P<0.001;q=11.650,P<0.001),Desmin (q=5.975,P<0.001;q=13.579,P<0.001),cTnT (q=7.133,P<0.001;q=17.548,P<0.001),and Cx43 (q=4.571,P=0.037;q=11.068,P<0.001),and down-regulated the mRNA (q=7.384,P<0.001;q=28.234,P<0.001) and protein (q=4.594,P=0.036;q=15.945,P<0.001) levels of KLF6.The apoptosis rate of miR-22-3p mimics group was lower than that of 5-AZA group (q=8.216,P<0.001).Compared with the miR-22-3p mimics+pcDNA group,miR-22-3p mimics+pcDNA-KLF6 up-regulated the mRNA(q=23.891,P<0.001) and protein(q=13.378,P<0.001)levels of KLF6,down-regulated the expression of Desmin (q=9.505,P<0.001),cTnT (q=10.985,P<0.001),and Cx43 (q=8.301,P<0.001),and increased the apoptosis rate (q=4.713,P=0.029).The dual luciferase reporter gene experiment demonstrated that KLF6 was a potential target gene of miR-22-3p. Conclusion MiR-22-3p promotes cardiomyocyte-like differentiation of BMSC by inhibiting the expression of KLF6.

There is a commonality between jingjin (muscle region of meridian) and the fascial network for coordinating the balance in the body. The occurrence and the progression of tumor may disrupt the overall coordination between the fascial network and jingjin directly or indirectly, thereby, the impairment of this coordination may result in cancer pain. Rooted on the theory of overall balance of the fascial network, and combined with understanding of pain in jingjin theory, professor HUANG Jin-chang emphasizes the importance of "relaxing the knot" in treatment of cancer pain. It is recommended to select the fascia reaction point as the target point, in accordance with the principle of balance adjustment and apply various acupuncture and moxibustion therapies, such as Fu's subcutaneous needling, small-needle scalpel therapy, fire needling, and moxibustion.

OBJECTIVES: To investigate the distribution of body mass index (BMI) and risk factors for obesity in children with Diamond-Blackfan Anemia (DBA). METHODS: The children with DBA who attended National Clinical Research Center for Blood Diseases, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, from January 2003 to December 2020 were enrolled as subjects. The related clinical data and treatment regimens were recorded. The height and weight data measured within 1 week before or after follow-up time points were collected to calculate BMI. The risk factors for obesity were determined by multivariate regression analysis in children with DBA. RESULTS: A total of 129 children with DBA were enrolled, among whom there were 80 boys (62.0%) and 49 girls (38.0%), with a median age of 49 months (range 3-189 months). The prevalence rate of obesity was 14.7% (19/129). The multivariate logistic regression analysis showed that the absence of ribosomal protein gene mutation was closely associated with obesity in children with DBA (adjusted OR=3.63, 95%CI: 1.16-11.38, adjusted P=0.027). In children with glucocorticoid-dependent DBA, obesity was not associated with age of initiation of glucocorticoid therapy, duration of glucocorticoid therapy, and maintenance dose of glucocorticoids (P>0.05). CONCLUSIONS There is a high prevalence rate of obesity in children with DBA, and the absence of ribosomal protein gene mutation is closely associated with obesity in children with DBA.

Objective: To explore the differences in subsequent analysis between metagenomic and 16Sr DNA sequencing in compositionally characterizing gut microbiota of healthy elderly. Methods: By using a panel study design, five monthly repeated measurements were performed among 76 healthy older people in Jinan City, Shandong Province. Their fecal samples were collected, and genomic DNA was extracted and analyzed through metagenomic and 16Sr DNA sequencing to compare the composition and diversity of gut microbiota. The correlation between species abundance and α diversity was analyzed by Pearson correlation analysis, and the correlation between species abundance and β diversity was determined by Procrustes analysis. Results: The age of 76 participants was (65.07±2.75), and the body mass index was (25.03±2.40) kg/m². There were 38 males and 38 females. A total of 345 fecal samples were obtained from five monthly repeated measurements . Compared with 16S rDNA sequencing, metagenomic sequencing showed more annotated species at each level. The difference in the number of two sequencing species increased with the decrease of the level. Although there were significant differences in species richness between the two sequencing methods. Their species richness was highly correlated at both phylum (r=0.88, P<0.001) and genus (r=0.77, P<0.001) levels. Bacteroidetes and Firmicutes were the common dominant species. Gut microbiota diversity analysis further showed that there was a significantly positive correlation between α diversity (r=0.70, P<0.001) and β diversities (M²=0.84, P<0.05) in the two groups. Conclusion: The annotation efficiency of metagenomic sequencing is much higher than that of 16S rDNA sequencing. The two sequencing methods are consistent in phylum abundance as well as α diversity.

This study used pharmacology combined with metabolomics to explore the effect of Amygdalus mongolica total extract on bleomycin induced pulmonary fibrosis in rats. The rat model of pulmonary fibrosis was established by intratracheal injection of bleomycin and treated with the total extract of Amygdalus mongolica. The pathological changes of lung tissue were evaluated by hematoxylin and eosin (HE) and Masson staining, the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in lung tissue were detected, and transforming growth factor β1 (TGF-β1), Smad family member 3 (Smad3), α-smooth muscle actin (α-SMA) pathway index expression in lung tissue was detected by fluorescence quantitative PCR. UPLC-Q-TOF/MS was used to study serum metabolomics to explore the changing patterns of biomarkers and the metabolic pathways affected by them. The results showed that compared with the model group, the medium (1.5 g·kg^-1) and high (3.0 g·kg^-1) doses of Amygdalus mongolica total extract could significantly reduce the lung index, significantly increase the activity of SOD in serum and lung tissue, reduce the degree of alveolar inflammation and pulmonary fibrosis, and reduce MDA in serum and lung tissue, and significantly reduce TGF-β1, Smad3, α-SMA mRNA expression in lung tissue. Serum metabolomics profile analysis identified 25 significantly different metabolites, the Amygdalus mongolica total extract can participate in linoleic acid metabolism, glycerophospholipid metabolism and alpha-linolenic acid metabolism by reducing five key biomarkers: lysoPE(0∶0/22∶5(4Z,7Z,10Z,13Z,16Z)), lysoPC(20∶0/0∶0), PC(20∶5(5Z,8Z,11Z,14Z,17Z)/15∶0), 12,13-dihydroxy-9-octadecenoic acid (12,13-DHOME), 9,10-dihydroxy-12-octadecenoic acid (9,10-DHOME) to affect pulmonary fibrosis. This study preliminarily revealed the action mechanism of Amygdalus mongolica total extract against pulmonary fibrosis in rats, and provided a reference basis for the clinical application of Amygdalus mongolica. The animal experiments were approved by the Medical Ethics Committee of Baotou Medical College (No.20170315).

ObjectiveThe purpose of this study was to analyze the correlation between SUVmax on primary prostate lesion of two-phase ⁶⁸Ga-PSMA-11 PET/CT and the clinicopathological features of patients with preliminary diagnosis of prostate cancer. MethodsPET/CT images of 19 patients with prostate cancer first diagnosed in our hospital from November 2017 to September 2020， aged 69.0±7.4 years， were collected. All patients underwent ⁶⁸Ga-PSMA-11 PET/CT dual-phase examination， and radical resection of prostate cancer was performed within two weeks. Semi-quantitative parameters of ⁶⁸Ga-PSMA-11 PET/CT on primary prostate cancer， SUVmax1 in the standard phase imaging， SUVmax2 in the delayed phase imaging and SUVmax3 （difference between SUVmax2 and SUVmax1）， were measured by automatic segmentation algorithm method. Clinical and pathological data of each patient were collected. Mann-Whitney U test and ROC curve analysis were used to compare SUVmax and the clinicopathological characteristics of patients in two independent samples. P<0.05 was considered as statistically significant difference. ResultsThe differences of SUVmax1， SUVmax2 and SUVmax3 between GS≤7 group and >7 group were statistically significant（P＜0.05）， and the areas under the ROC curves were 0.845， 0.845 and 0.893， respectively. SUVmax1， SUVmax2 and SUVmax3 were significantly different between ISUP grade ≤2 group and >2 group （P<0.05）， and the areas under the ROC curve were 0.773， 0.784 and 0.852， respectively. The difference of SUVmax3 between T stage ≤T2 group and >T2 group was statistically significant （P<0.05）， while the difference of SUVmax1 and SUVmax2 between T stage ≤T2 group and >T2 group was not statistically significant （P>0.05）. The difference of SUVmax3 between D’ Amico low-medium-risk group and high-risk group was statistically significant （P<0.05）， while the difference of SUVmax1 and SUVmax2 between D’ Amico low-medium-risk group and high-risk group was not statistically significant （P>0.05）. There was no significant difference in SUVmax1， SUVmax2 and SUVmax3 between total PSA ≤20 ng/mL group and >20 ng/mL group （P>0.05）. SUVmax1， SUVmax2 and SUVmax3 were significantly different between positive nerve invasion group and negative group （P<0.05）， and the areas under the ROC curves were 0.872， 0.923 and 0.974， respectively. ConclusionsSUVmax2 and SUVmax3 were positively correlated with multiple clinical and pathological features of prostate cancer. Compared with standard phase imaging， dual-phase imaging of ⁶⁸Ga-PSMA-11 PET/CT may provide more favorable value in predicting the clinical and pathological features of prostate cancer patients before surgery.

Performance management is a key direction of the reform of the national medical and health system, and it is also an important starting point for promoting the development of hospital connotation. In view of the contradiction among the current hospital performance distribution system, this paper proposes a design mentality of performance distribution system based on homogenization subsidy base, and expounds the basic connotation and cognitive basis of homogenization subsidy base. The key elements of the design of the performance distribution system are discussed from four aspects: pre-adjusted total control, coefficientized personnel attendance, same performance appraisal, and homogenization subsidy base. At the same time, this paper also analyzes the characteristics of the performance distribution system based on the homogenization subsidy base. The application prospects of the performance distribution system are prospected from three aspects: the national medical reform requirements, the discipline development discipline and the system's own characteristics.
