To explore the relationships between traditional Chinese medicine (TCM) constitutional types and overweight or obesity so as to provide evidence for adjusting constitutional bias and preventing and treating obesity.

Medicinal animals are important part of Traditional Chinese medicine resources in China. Cytochrome c oxidase subunit I (COI) was selected as the standard DNA barcoding sequence for animal medical materials. In this study, the 51 animal species from 45 animal medical materials in the Chinese Pharmacopoeia were selected and the intra-specific variation and the inter-specific divergence, the barcoding gap, the identification efficiency of their COI sequences were analyzed. The results showed that the inter-specific divergence is higher than intra-specific distance. The barcoding gap existed between inter-specific sequence divergence and intra-specific dis-tance. The identification efficiencies were 100% both at the genus and species level except the Arthropoda. The cluster dendrogram exhibited that different species distinguished from others. Therefore, COI sequence as a bar-code is suitable to identify the species of animal medical materials in Chinese Pharmacopoeia.

Objective:To explore the basic biological characteristics of lncRNA B230352I09 and its role in the process of myocardial injury.Methods:We analyzed the biological characteristics of lncRNA B230352I09 on the UCSC website and predicted the possible binding protein of lncRNA B230352I09 by the catRAPID. Real-time fluorescence quantitative (RT) PCR method was applied to detect the expression of lncRNA B230352I09 in heart tissues at different time points (0, 1, 3, 7d) within 7 days after birth, the organs distribution and expression of lncRNA B230352I09 in neonatal mouse and the expression pattern of lncRNA B230352I09 in the heart of mice with myocardial injury. In addition, we constructed hypoxia model by culturing primary cardiomyocytes to detect the effect of lncRNA 230352I09 overexpression on hypoxic cardiomyocyte apoptosis by Hoechst staining kit, the effect of lncRNA B230352I09 overexpression on ROS content of hypoxic cardiomyocyte by DCFDA probe and changes in mitochondrial membrane potential of hypoxic cardiomyocytes by JC-1 Fluorescent probes.Results:Full-length of mouse B230352I09 was 663bp, located in the chr7:123031415-123066439 forward strand. RBBP6 gene was adjacent to B230352I09, which may be the target of lncRNA B230352I09 by catrapid prediction analysis. With the development of the heart, the expression level of lncRNA B230352I09 showed a gradual downward trend. The main expression organs of lncRNA B230352I09 in 1-day-old mice were heart, brain, kidney and liver. In heart tissue, lncRNA B230352I09 expression in non-cardiomyocytes was significantly less than in cardiomyocytes [ (1.0± 0.03) vs. (9.2± 3.29), P=0.013]. After myocardial injury, the expression level of lncRNA B230352I09 showed an increasing trend compared with the normal developing mice, but there was no statistical significance. Hoechst staining showed that lncRNA B230352I09 could inhibit the apoptosis of hypoxic cardiomyocytes. Detecting the content of ROS in cardiomyocytes showed that compared with the hypoxia group, the generation of ROS was significantly reduced in the lncRNA B230352I09 overexpression group ([(3.8±0.71) vs. (1.65±0.56), P=0.015]). JC-1 fluorescent probe was used to detect the mitochondrial membrane potential, and the results showed that the mitochondrial membrane potential of cardiomyocytes in the lncRNA B230352I09 overexpression group was significantly higher than that in the hypoxia group. Conclusions:In heart tissue, lncRNA B230352I09 was mainly expressed in cardiomyocytes. LncRNA B230352I09 has a protective effect in the process of myocardial injury in mice, mainly by inhibiting apoptosis of cardiomyocytes, reducing ROS production, and protecting mitochondrial membrane potential of cardiomyocytes.

AO type C thoracolumbar fractures are the most serious type of spinal fractures. Among them, the non-displaced type C fractures are easy to be misdiagnosed and mistreated because of their atypical imaging manifestations and few associated neurological symptoms, which ultimately lead to serious consequences such as treatment failure and paralysis. MRI examination is crucial for a correct diagnosis, but most orthopedic surgeons make a diagnosis largely based on the results of X-ray and CT examinations, in which type C fractures are easily misdiagnosed as type B. Non-displaced type C fractures involve three-column injuries and require surgical treatment, for which the key is to fully reconstruct the stability of the three columns. However, in the current clinical practice, it is common to use simple posterior fixation only, resulting in treatment failure. To this end, the authors conducted an in-depth discussion on the diagnosis and treatment of non-displaced AO type C thoracolumbar fractures, aiming to improve orthopedic clinicians ′ understanding and awareness of their significance.

Objective:To explore the early identification, diagnosis and pathogenesis of childhood acute lymphoblastic leukemia (ALL) complicated with cytokine release syndrome(CRS).Methods:The clinical data of childhood ALL complicated with CRS admitted to Shenzhen Children's Hospital in February 2021 were retrospectively analyzed. The relevant literature was reviewed.Results:The little girl was 2 months and 11 days of age and was diagnosed with ALL with MLL rearrangement positive by bone marrow aspiration because of abdominal mass and abnormal hemogram. She had recurrent high fever with pulmonary imaging characteristic changes during the early intensive induction chemotherapy, accompanied by the elevated interlukin (IL)-2, IL-6, IL-10 and interferon (IFN)-γ. Finally, she was diagnosed with ALL complicated with CRS. Glucocorticoid therapy showed a good efficacy and her clinical symptoms improved.Conclusions:ALL complicated with CRS is essentially induced by cytarabine syndrome drugs in the chemotherapy. The main clinical manifestations include recurrent high fever accompanied by the elevated IL-2, IL-6, IL-10 and IFN-γ. The symptomatic and supportive therapy is usually based on glucocorticoids. Early identification and diagnosis can reduce adverse drug reactions and improve the life quality of children.

Objective:To investigate the value of antithrombin Ⅲ (AT-Ⅲ) in evaluating patients with decompensated hepatitis B liver cirrhosis and complicated with esophagogastric variceal bleeding (EVB).Methods:From January 1, 2018 to December 31, 2021, clinical data of 193 hospitalized patients with hepatitis B liver cirrhosis diagnosed in the Second Hospital of Shanxi Medical University were retrospectively analyzed, which included coagulation indicator (AT-Ⅲ), liver function indicators (total bilirubin, etc.), abdominal ultrasound results (portal vein diameter, portal vein blood flow velocity), and the occurrence of esophagogastric varices. According to the presence or absence of main complications, 193 patients with hepatitis B liver cirrhosis were divided into compensated group (60 cases) and decompensated group (133 cases). According to the presence or absence of EVB, 133 patients of decompensated group were divided into non-bleeding subgroup (96 cases) and bleeding subgroup (37 cases). The above indicators were compared among compensated group, decompensated group and their subgroups. The independent related factors of decompensated hepatitis B liver cirrhosis and EVB were analyzed. The level of AT-Ⅲ of each group were compared, and the relationship between AT-Ⅲ and Child-Pugh score was analyzed. The diagnostic capability of AT-Ⅲ in decompensated hepatitis B liver cirrhosis and complicated with EVB were analyzed. Mann-Whitney U test, independent sample t test, chi-square test, multiple logistic regression analysis, Pearson correlation analysis and receiver operating characteristic curve (ROC) analysis were used for statistical analysis. Results:The total bilirubin level of the decompensated group was higher than that of the compensated group, the portal vein diameter was larger than that of the compensated group, and the portal vein blood flow velocity was lower than that of the compensated group (31.50 μmol/L (21.90 μmol/L, 48.80 μmol/L) vs. 19.40 μmol/L (15.00 μmol/L, 25.50 μmol/L); (14.31±3.53) mm vs. (12.57±3.83) mm; (13.39±3.49) cm/s vs. (15.08±4.28) cm/s), and the differences were statistically significant ( Z=-5.76, t=-2.78 and 2.40; P<0.001, =0.006 and 0.018). The incidence of esophagogastric varices of the compensated group and the decompensated group was compared (40.0%, 24/60 vs. 87.2%, 116/133), and the difference was statistically significant ( χ2=64.06, P<0.001). The diameter of portal vein of the bleeding subgroup was larger than that of the non-bleeding subgroup, and the portal vein blood flow velocity was lower than that of the non-bleeding subgroup ((15.54±4.23) mm vs. (13.87±3.16) mm; (12.05±3.12) cm/s vs. (13.85±3.51) cm/s), and the differences were statistically significant ( t=-2.15 and 2.23, P=0.034 and 0.028). The AT-Ⅲ levels gradually decreased in the non-bleeding subgroup and bleeding subgroup of the compensated group and decompensated group, which were (79.52±16.02)%, (63.91±19.96)% and (35.92±13.69)%, respectively, the difference was statistically significant ( F=5.71, P=0.018). The AT-Ⅲ level of the compensated group was higher than that of the non-bleeding subgroup and the bleeding subgroup of the decompensated group, and the AT-Ⅲ level of the non-bleeding subgroup of the decompensated group was higher than that of the bleeding subgroup, and the differences were statistically significant ( t=5.11, 13.74 and 7.84, all P<0.001). The results of multivariate logistic regression analysis showed that total bilirubin and AT-Ⅲ were independent related factors of decompensation of hepatitis B liver cirrhosis ( OR (95% confidence interval (95% CI) 1.060 (1.018 to 1.104) and 0.945 (0.922 to 0.970), P=0.005 and <0.001). AT-Ⅲ was an independent related factor of decompensation of hepatitis B liver cirrhosis and complicated with EVB ( OR(95% CI) 0.902 (0.856 to 0.950, P<0.001). AT-Ⅲ was negatively correlated with Child-Pugh score ( r=-0.559, P<0.001). ROC analysis showed that the cut-off values of AT-Ⅲ in the diagnosis of decompensated stage of hepatitis B liver cirrhosis and complicated with EVB were 62.5% and 61.5%, the sensitivity was 88.3% and 89.2%, the specificity was 70.7% and 61.5%, and the area under the curve (95% CI) was 0.815 (0.755 to 0.874, P<0.001) and 0.899 (0.828 to 0.971, P<0.001), respectively. Conclusion:AT-Ⅲ is an important indicator in evaluating the severity of disease progression in patients with hepatitis B liver cirrhosis, and it has a certain clinical value in evaluating the bleeding tendency of patients with decompensated hepatitis B liver cirrhosis and complicated with esophagogastric varices.

ObjectiveThe type 2C protein phosphatases （PP2C） are involved in numerous plant signal transduction pathways. They mainly participate in plant stress response and regulate second metabolites biosynthesis via negatively regulating MAPK signaling pathway. Herein，we were to identify and analyze PP2C （CsPP2C） gene family from hemp genome，in hope of providing comprehensive insights for studying CsPP2C function during the development of hemp. MethodMolecular Evolutionary Genetics Analysis （MAGA）-X was used to construct phylogenetic tree. Expert Protein Analysis System （ExPASy），WoLF PSORT，Multiple EM for Motif Elicitation （MEME），Batch Conserved Domain Search （Batch-CD-Search），PlantCare，and TBtools were used，respectively，to predict CsPP2C physicochemical properties，subcellular localization，conserved motifs，protein structure，cis-element in promoter and collinearity with Arabidopsis PP2C. Cannabis sativa transcriptome and Real-time polymerase chain reaction（Real-time PCR） were used to analyze and verify gene expressions，respectively. ResultFifty-two CsPP2C with conserved domains were identified from the entire genome of hemp，encoding proteins ranging from 244 to 1 089 aa in length and with molecular weights ranging from 26.76 to 122.53 kDa. Those genes were mainly distributed in the nucleus，cytoplasm and chloroplast. The 47 CsPP2C were divided into 10 subfamilies，and the remaining 5 were not clustered. Seven pairs of homologous genes between hemp and Arabidopsis thaliana were identified according to collinear analysis. The light-responsive elements and abscisic acid elements are most abundant in the prediction. The gene expression heat map showed varied expression pattern of CsPP2C in different tissues. Real-time PCR results of three CsPP2C were consistent with transcriptome data. Moreover，alternative splicing analysis showed that some CsPP2C had alternative-splicing genes during evolution. ConclusionWe predicted and analyzed CsPP2C gene family in genomic scale and showed that CsPP2C are involved in many biological processes，whereby provides foundation for CsPP2C functional study.
