Objective To investigate the relationship between the changes of serum human surfactant pro-tein D(SP-D)and vascular cell adhesion molecule-1(sVCAM-1)levels and postoperative fracture healing and short-term prognosis in patients with traumatic rib fractures.Methods A total of 102 patients with traumatic rib fractures who were treated in Banan Hospital Affiliated to Chongqing Medical University from January 2020 to December 2021 were selected as the research objects.After 8 months of treatment,the healing status of the patients was analyzed and divided into non-healing group(21 cases)and healing group(81 cases).Ac-cording to the pulmonary contusion,the patients were divided into pulmonary contusion group(19 cases)and non-pulmonary contusion group(83 cases).The serum levels of SP-D and sVCAM-1 were compared between the healing group and the non-healing group,and between the pulmonary contusion group and the non-pulmo-nary contusion group.The relationship between the changes of serum SP-D and sVCAM-1 levels and postop-erative fracture healing and short-term prognosis in patients with traumatic rib fractures were studied.Results The levels of SP-D and sVCAM-1 in the healing group were lower than those in the non-healing group(P＜0.05).The levels of SP-D and sVCAM-1 in the non-pulmonary contusion group were lower than those in the pulmonary contusion group(P＜0.05).Serum SP-D and sVCAM-1 levels were independent risk factors for postoperative fracture healing and short-term prognosis.Conclusion The changes of serum SP-D and sVCAM-1 levels in patients with traumatic rib fractures are related to fracture healing and short-term prognosis,which can be used as an important reference for prognosis evaluation.

Objective To analyze the combined effect of body mass index(BMI)and age with cancer occurrence among a hypertensive population in Minhang District,Shanghai.Methods Participants of this study were 212 394 hypertensive patients without cancer in Minhang District,Shanghai,registered in the electronic health information system from 2007 to 2015.Age and BMI were included as smoothing functions in the generalized additive Cox proportional risk model.The bivariate response model was constructed to visualize results using surface plots and to comprehensively analyze the association of BMI and age with the risk of cancer occurrence.Results A total of 22 141 participants developed cancer by Dec 31,2018.The association between age and the risk of cancer incidence showed an overall linear trend while the association between BMI and the risk of cancer incidence showed an overall"U"shape.BMI at about 26 kg/m2 showed the lowest risk of cancer incidence.The risk of cancer occurrence increased with increasing age in people with different BMIs.The associations between BMI and the risk of cancer incidence were different at different age groups:there was no significant association between BMI and the risk of cancer incidence in the young people(20-44 years).While in the middle-aged and older people aged over 45 years,BMI was associated with the risk of cancer incidence in a"U"shape.The lowest risk of cancer incidence was around the BMI of 26 kg/m2.Conclusion BMI among the population with hypertension should be controlled in a reasonable range,especially in the middle-aged and older population,to prevent cancer occurrence.

italic>Artemisia argyi is a traditional Chinese medicine in China, which is used as medicine with its leaves. The leaves of A. argyi mainly contain flavonoids, phenolic acids, volatile oils and other compounds, and have a variety of pharmacological activities. AP2/ERF transcription factors are abundant in plants and are mainly involved in plant growth and development, abiotic stress response and secondary metabolite biosynthesis regulation. However, there are few reports on the AP2/ERF gene family and its functions in A. argyi. In this study, we systematically identified the AP2/ERF gene family in A. argyi genome, and analyzed its phylogenetic tree, protein physicochemical properties, subcellular localization, conserved motifs, promoter elements, and expression patterns. The results showed that a total of 204 AP2/ERF transcription factors were identified in A. argyi genome, encoding proteins consisting of 88-483 amino acids with a relative molecular mass of 10-52.94 kDa and a theoretical isoelectric point of 4.62-9.88. Subcellular prediction showed that the majority of AP2/ERFs were located in the nucleus, cytoplasm, and the minority of them is located in the membrane and chloroplasts. According to the Arabidopsis AP2/ERF family classification, A. argyi AP2/ERF proteins were divided into four subfamilies: Soloist, AP2, ERF (B3, B4, B5, B6), and DREB (A1, A2, A4, A5, A6), among which DREB family accounted for the largest proportion, and the same subfamily had similar conserved motifs. cis-Acting element analysis showed that AP2/ERF promoters have a large number of elements responding to light and abiotic stress. Expression pattern analysis showed that most of the genes of the AP2/ERF family were dominantly expressed mainly in roots and stems, of which 19 were dominantly expressed in leaves, 77 would be induced to be expressed by methyl jasmonate, of which 16 genes were both dominantly expressed in leaves and induced to be expressed by methyl jasmonate, and these AP2/ERF genes may be the key regulatory genes for the synthesis of active ingredients in A. argyi leaves.This study lays the foundation for the functional study of AP2/ERF family genes and their regulating roles in the active components biosynthesis in A. argyi leaves.

Purpose: Loss-of-function mutations in the adenomatous polyposis coli (APC) gene are common in metastatic colorectal cancer (mCRC). However, the characteristic of APC specific mutations in mCRC is poorly understood. Here, we explored the clinical and molecular characteristics of N-terminal and C-terminal side APC mutations in Chinese patients with mCRC. Materials and Methods: Hybrid capture-based next-generation sequencing was performed on tumor tissues from 275 mCRC pati-ents to detect mutations in 639 tumor-associated genes. The prognostic value and gene-pathway difference between APC specific mutations in mCRC patients were analyzed. Results: APC mutations were highly clustered, accounting for 73% of all mCRC patients, and most of them were truncating mutations. The tumor mutation burden of the N-terminal side APC mutations group (n=76) was significantly lower than that of the C-terminal side group (n=123) (p < 0.001), further confirmed by the public database. Survival analysis showed that mCRC patients with N-terminus side APC mutations had longer overall survival than C-terminus side. Tumor gene pathway analysis showed that gene mutations in the RTK/RAS, Wnt and transforming growth factor β signaling pathways of the C-terminal group were significantly higher than those of the N-terminal group (p < 0.05). Additionally, KRAS, AMER1, TGFBR2, and ARID1A driver mutations were more common in patients with C-terminal side APC mutations. Conclusion APC specific mutations have potential function as mCRC prognostic biomarkers. There are obvious differences in the gene mutation patterns between the C-terminus and N-terminus APC mutations group, which may have certain guiding significance for the subsequent precise treatment of mCRC.

italic>Artemisia argyi (A. argyi) is a Chinese herbal medicine in China. The main active components are volatile oils, flavonoids, and other compounds, which have various pharmacological activities. Methoxylated flavonoids are the main active ingredients in A. argyi. Flavonoid O-methyltransferase (FOMT) is a key enzyme in the O-methylation of flavonoids. In order to further understand the function and characteristics of FOMT proteins, this paper carried out the whole genome mining and identification of FOMT genes in A. argyi and performed phylogenetic, chromosomal localization, gene sequence characterization, subcellular localization prediction, protein structure, gene structure analysis, and expression pattern analysis. The results showed that a total of 83 FOMT genes were identified in the genome of A. argyi. The phylogenetic tree shows that FOMT genes are divided into two subgroups, CCoAOMT (caffeoyl CoA O-methyltransferase) subfamily (32 genes) and COMT (caffeic acid O-methyltransferase) subfamily (51 genes). Gene sequence analysis showed that the number of amino acids encoded by FOMT was 70-734 aa, the molecular weight was 25 296.55-34 241.3 Da, and the isoelectric point was 4.51-9.99. Compared with 32 members of the CCoAOMT subfamily, nearly 1/3 of the 51 members of the COMT subfamily were hydrophobic proteins and 2/3 were hydrophilic proteins. Subcellular localization prediction showed that more than 80% of CCoAOMT subfamily members were located in the cytoplasm, and 96% of COMT subfamily members were located in the chloroplast. COMT subfamily members have more motifs than CCoAOMT subfamily members. The N-terminal motifs of COMT subfamily proteins are relatively variable, while the C-terminal motifs are relatively conserved. Expression pattern analysis showed that CCoAOMT subfamily members were mainly expressed in roots, while COMT members were mainly expressed in leaves. Some FOMTs showed the tissue expression specificity by real-time quantitative PCR analysis, especially in leaves. In this study, we identified and analyzed the FOMT gene family in A. argyi, and provided a theoretical basis for further research on the function of FOMTs and the biosynthesis of methylated flavonoids in A. argyi.

OBJECTIVE: To determine the thermic effect of food (TEF) in a Chinese mixed diet in young people. METHODS: During the study, the participants were weighed and examined for body composition every morning. The total energy expenditure (TEE) of the participants was measured by the doubly labeled water method for 7 days, and during this period, basal energy expenditure was measured by indirect calorimetry and physical activity energy expenditure was measured by an accelerometer. The value obtained by subtracting basal energy expenditure and physical activity energy expenditure from TEE was used to calculate TEF. RESULTS: Twenty healthy young students (18-30 years; 10 male) participated in the study. The energy intake of the participants was not significantly different from the Chinese Dietary Reference Intake of energy ( P > 0.05). The percentage of energy from protein, fat and carbohydrate were all in the normal range. The intakes of fruits, milk and dietary fiber of the participants were significantly lower than those in the Chinese Dietary Guidelines ( P < 0.05). There was no significant difference in the body weight of the participants during the experiment ( P > 0.05). When adjusted for body weight, there was no significant difference in either TEE or basal energy expenditure between the male and female participants ( P > 0.05). In addition, there was no significant difference in physical activity energy expenditure and TEF between the male and female participants ( P > 0.05). The percentage of TEF in TEE was 8.73%. CONCLUSION The percentage of TEF in TEE in a Chinese mixed diet in young people was significantly lower than 10% ( P < 0.001). A value of 10% is usually considered to be the TEF in mixed diets as a percentage of TEE.

Aim To explore the effect of astragaloside IV (AS-IV) on cell proliferation and collagen expression in cardiac fibroblasts (CFs) of rats induced with angiotensin II (Ang II) and its mechanism. Methods CFs were pretreated with short-chain acyl-CoA dehydrogenase (SCAD) siRNA1186 for 12 h and then co-treated with Ang TJ and AS-IV for 36 h. The expressions of SCAD, α-SMA, collagen I and collagen III in CFs were detected by Western blot. mRNA expression levels of SCAD, a-SMA, collagen I and collagen III in CFs were detected by quantitative real-time PCR. The SCAD enzymatic activity, the content of ATP, hydroxyproline and free fatty acid were measured by detection kits. Results The expression of α-SMA, collagen I and collagen III were up-regulated (all P < 0. 01) in CFs induced by Ang II compared with the control cells, and the expression and enzymatic activity of SCAD significantly decreased (P < 0. 01, P< 0. 05). The content of ATP decreased (P < 0.01), and the content of hydroxyproline and free fatty acids increased (all P < 0.01). Compared with Ang II group, SCAD expression and enzymatic activity, and ATP content were significantly increased (all P < 0.01) in Ang II + AS-TV group, but the content of hydroxyproline and free fatty acids, and the expression of α-SMA, collagen I and collagen III significantly decreased (all P < 0.01). However, compared with the Ang II + NC group, there was no significant difference in all indices in the Ang II + SiRNA1186 + AS-TV group. The protective effect of AS-TV on Ang II -induced cell proliferation and collagen expression in CFs was eliminated by the interference of SCAD SiRNA1186. Conclusions AS-IV may inhibit Ang II-induced cell proliferation and collagen expression in CFs by activating SCAD.

【Objective】 To analyze the characteristics and influencing factors of blood transfusion in patients undergoing hepatectomy with hydatid hepatica, so as to provide perioperative blood security of these patients. 【Methods】 A retrospective analysis was performed on 40 hydatid hepatica patients who underwent hepatectomy from June 2011 to June 2021, and they were divided into the transfusion group (n=15) and the non-transfusion group (n=25). The difference in basic information, operative information, blood routine, coagulation function, biochemical parameters and thromboelastogram between the two groups were compared, and the characteristics of perioperative blood transfusion were analyzed. 【Results】 Fifteen(37.5%, 15/40) patients undergoing hepatectomy received blood transfusion, among which 2(5%, 5/40), 10(25%, 10/40) and 11(27.5%, 11/40) received preoperative, intraoperative and postoperative transfusion, respectively. The average transfusion of suspended red blood cells, plasma and cryoprecipitate were 4.77 U, 1 355 mL and 11.9 U respectively, without any adverse reactions of blood transfusion occurred. The operative time, intraoperative blood loss, the number of patients with tumor diameter ≥10 cm/ diameter <10 cm, the number of patients with cholecystectomy, postoperative PT, postoperative APTT and average hospital stay in the transfusion group were higher than those in the non-transfusion group(P<0.05), and the postoperative FIB was lower than those in the non-transfusion group(P<0.05). The blood test results showed that the WBC, AST, ALT and INR 24h after operation were significantly higher than those before operation (P<0.05), while RBC, Hb, ALP, FIB and Angle were significantly lower than those before operation(P<0.05). There were statistically significant differences in WBC, RBC, Hb, ALT, ALP and INR between preoperative and postoperative 3~5 days(P<0.05). The differences of WBC, AST, ALT and FIB 3~5 days after surgery were statistically significant compared with 24 hours after surgery(P<0.05). 【Conclusion】 The size of hepatic hydatid mass, cholecystectomy, intraoperative blood loss, operative time, postoperative PT, postoperative APTT and postoperative FIB were important factors affecting perioperative blood transfusion after hepatectomy, and the main transfusion components were plasma and cryoprecipitate.

【Objective】 To explore the corresponding strategies of blood preparation for placenta previa operation in our hospital according to the situation of blood transfusion during and after operation. 【Methods】 Ninety pregnant women with placenta previa (complete, partial or marginal) undergoing the caesarean operation and blood transfusion in our hospital from January 2011 to September 2020 were selected as the research objects. The corresponding data about intraoperative/postoperative blood loss, blood transfusion and blood preparation were collected, analyzed and compared. 【Results】 There was no significant differences in age between complete and marginal placenta previa(P>0.05), but significant differences in intraoperative/postoperative blood loss and the units of blood transfusion (P<0.05). The blood loss of marginal placenta previa was less (≤1 000 mL) and the units of blood transfusion were mainly 3 (2, 3) U. Complete placenta previa was more likely to cause serious postpartum bleeding (>1 000 mL). The difference between ordering and transfusion units of complete and marginal placenta previa were 0.4 and 0, respectively. When the complete placenta previa was accompanied by placenta increta or placenta percreta, the blood loss was larger (>1 000 mL) and the units of blood transfusion ranged from 4.5 U to 6 U, while the blood loss was generally low (≤1 000 mL) and the units of blood transfusion was concentrated at 3 (2, 4) U without placenta accreta nor implantation.The difference between ordering and transfusion units of complete placenta previa with non-implantation, placenta accreta, placenta increta and placenta percreta were 0.165, 0.33, 0.5 and 1, respectively. 【Conclusion】 For marginal placenta previa, 3U blood is recommended for routine preparation, 3U blood for complete placenta previa with non-implantation or placenta accrete, and 4.5-6U for complete placenta previa with placenta increta or placenta percreta.
