Objective To investigate the multi spiral computed tomography(MSCT)characteristics and biological behaviors of advanced gastrointestinal signet ring cell carcinoma(SRCC),so as to provide accurate preoperative type,stage and personalized choice of treatment strategy in clinical practice.Methods The clinical manifestations,five tumor markers and MSCT imaging data of 26 cases(group A)with advanced gastrointestinal SRCC confirmed by surgical or endoscopic biopsy and pathological immunohistochemistry were analyzed retrospectively,and 44 cases(group B)of advanced non-signet ring cell carcinoma(NSRCC)during the same period were randomly selected as the control group.The clinical manifestations,five tumor markers and MSCT imaging features of groups A and B were analyzed.Results There were no significant differences in gender,tumor location,tumor thickness(T)and length(L),and five tumor markers between groups A and B(P＞0.05).There were significant differences in age,main symptoma,tumor thickness-to-length ratio(TLR),angle between cancerous edge and normal tissue(CNA)(P＜0.05).However,age of group A and group B[group A≤50 years old(12/26,46％),group B＞50 years old(42/44,95％)],main symptom(x2=19.085,P＜0.05),tumor TLR(Z=-2.044,P＜0.05)and CNA(x2=14.776,P＜0.05)were significantly different(P＜0.05).Conclusion SRCC affects younger patients and is more likely to originate from the middle and lower parts of the stomach and rectum,with lower TLR,obtuse angle of CNA,and"caterpillar-like"characteristics of colorectal SRCC.

Objective To investigate the current status of knowledge-attitude-practice of cardiac rehabilitation in patients undergoing coronary artery bypass grafting(CABG) and analyze its influencing factors. Methods From July to November 2022, 288 patients with CABG in the coronary heart disease surgery center of Beijing Anzhen Hospital Affiliated to Capital Medical University were conveniently included, and general information questionnaire and cardiac rehabilitation knowledge and practice questionnaire were used to investigate the general situation and the level of knowledge-attitude-practice of cardiac rehabilitation in patients with coronary heart disease. Results A total of 290 questionnaires were sent out in this study, and 288 were effectively collected, with an effective recovery rate of 99.31%. The total score of the questionnaire was (106.81±13.35), and the total score rate was 62.83%, including the knowledge questionnaire scoring (39.34±9.13), belief questionnaire scoring (32.86±3.39) and behavior questionnaire scoring (34.61±3.54). The scoring rates of knowledge, attitude and practice questionnaire were 46.28%, 82.15% and 76.91%, respectively. Multiple linearregression analysis showed that patients who lived in rural areas, had education background of primary school or below, were farmers, had public health insurance, and had no previous coronary intervention, had lower levels of knowledge-attitude-practice of cardiac rehabilitation (P < 0.05). Conclusion The knowledge-attitude-practice of cardiac rehabilitation, especially the level of knowledge, in patients with CABG is needed to be improved. The factors that affect the level of knowledge-attitude-practice of cardiac rehabilitation in this population are diversified, suggesting that individual cardiac rehabilitation guidance should be implemented according to different people and local conditions, and diversified cardiac rehabilitation models should be established to improve the long-term and compliance of cardiac rehabilitation.

Objective:To analyze the status of the dyadic coping in spouses of young and middle-age cervical cancer patients undergoing synchronous radiotherapy and chemotherapy, and to explore the influencing factors in bi-directional of patients and their spouses.Methods:With the convenience sampling method, a total of 150 cervical cancer patients undergoing synchronous radiotherapy and chemotherapy who were hospitalized in the Radiotherapy Department of Tianjin Medical University Cancer Institute and Hospital from March 2021 to February 2022 and their spouses were selected. A cross-sectional study was conducted by the Dyadic Coping Inventory, the Lock-Wallace Marital Adjustment Test, the General Self-Efficacy Scale, the Hospital Anxiety and Depression Scale, etc. Besides, multiple linear regression was used to identify predictors of the dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy.Results:The total score of dyadic coping, marital quality, general self-efficacy, anxiety and depression in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (121.69 ± 19.67), (97.23 ± 25.05), (25.13 ± 5.19), (9.98 ± 3.46), (8.19 ± 4.06) points. The scores of anxiety and depression of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (10.57 ± 3.60), (9.10 ± 4.12) points. Multiple linear regression analysis showed that factors of the patients′ anxiety and depression, spouse′s perception of marital quality, spouse′s general self-efficacy, changes in family relationship, family income, and period of radiotherapy were the main influencing factors ( P<0.01), which accounted for 55.7% of total variation. Conclusions:The level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy was medium, the marriage quality remains to be further improved,and its influence factors involved in the bi-directional of patient and spouse, including patients′ anxiety and depression, the changes of the family relationship, period of radiotherapy, spouses perception of marital quality and self-efficacy and family income. Clinical medical staff can improve the level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy by improving their cognition of disease, reducing the incongruence of dyadic illness appraisals, and taking multiple measures to reduce the economic burden felt of the spouses.

MADS-box gene family is a significant transcription factor family that plays a crucial role in regulating plant growth, development, signal transduction, and other processes. In order to study the characteristics of MADS-box gene family in Docynia delavayi (Franch.) Schneid. and its expression during different stages of seed germination, this study used seedlings at different stages of germination as materials and screened MADS-box transcription factors from the transcriptome database of D. delavayi using bioinformatics methods based on transcriptome sequencing. The physical and chemical properties, protein conservative motifs, phylogenetic evolution, and expression patterns of the MADS-box transcription factors were analyzed. Quantitative real-time PCR (qRT-PCR) was used to verify the expression of MADS-box gene family members during different stages of seed germination in D. delavayi. The results showed that 81 genes of MADS-box gene family were identified from the transcriptome data of D. delavayi, with the molecular weight distribution ranged of 6 211.34-173 512.77 Da and the theoretical isoelectric point ranged from 5.21 to 10.97. Phylogenetic analysis showed that the 81 genes could be divided into 15 subgroups, among which DdMADS27, DdMADS42, DdMADS45, DdMADS46, DdMADS53, DdMADS61, DdMADS76, DdMADS77 and DdMADS79 might be involved in the regulation of ovule development in D. delavayi. The combination of the transcriptome data and the qRT-PCR analysis results of D. delavayi seeds indicated that DdMADS25 and DdMADS42 might be involved in the regulation of seed development, and that DdMADS37 and DdMADS38 might have negative regulation effects on seed dormancy. Previous studies have reported that the MIKC^* subgroup is mainly involved in regulating flower organ development. For the first time, we found that the transcription factors of the MIKC^* subgroup exhibited a high expression level at the early stage of seed germination, so we speculated that the MIKC^* subgroup played a regulatory role in the process of seed germination. To verify the accuracy of this speculation, we selected DdMADS60 and DdMADS75 from the MIKC^* subgroup for qRT-PCR experiments, and the experimental results were consistent with the expression trend of transcriptome sequencing. This study provides a reference for further research on the biological function of D. delavayi MADS-box gene family from the perspective of molecular evolution.

Diabetic peripheral neuropathy （DPN） is one of the common complications of diabetes. The disease has a long course with nerve pain and other symptoms， seriously affecting the quality of life of patients. DPN is related to high glucose in vivo， inflammation， oxidative stress， apoptosis， and autophagy， involving phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， and other signaling pathways. At present， the treatment of DPN mainly focuses on symptomatic treatments such as blood glucose control and neurotrophic therapy， but the effect is not ideal. Therefore， it is particularly important to select a reasonable and effective drug to prevent and treat DPN. In recent years， Chinese medicine has played an important role in the treatment of DPN. Many studies have explored the mechanism of Chinese medicine in the treatment of DPN， and it has been found that some Chinese medicine monomers and compounds can regulate signaling pathways to prevent and treat DPN. This paper reviewed the research results of signaling pathways involved in DPN and the regulation of related pathways by Chinese medicine， aiming to provide references for the clinical treatment of DPN.

Objective:To clarify the clinical efficacy of first-line oral antiviral drugs tenofovir alafenamide (TAF), tenofovir disoproxil fumarate (TDF), and entecavir (ETV) in the treatment of chronic hepatitis B (CHB) and their safety profiles with lipid, bone, and kidney metabolism.Methods:458 CHB cases diagnosed and treated at the Department of Hepatology of Integrated Traditional Chinese and Western Medicine of the Third Hospital of Hebei Medical University from February 2010 to November 2022 were selected. TAF (175 cases), TDF (124 cases), and ETV (159 cases) were used as therapies. At 24 and 48 weeks, the virology, biochemical response, changes in liver stiffness measurement (LSM), and bone, kidney, and blood lipid metabolism safety profiles were compared and analyzed.Results:After 24 and 48 weeks of TAF, TDF, and ETV therapy, HBV DNA load decreased by 3.28, 2.69, and 3.14 log10 IU/ml and 3.28, 2.83, and 3.65 log10 IU/ml, respectively, compared with the baseline, and the differences between the three groups were statistically significant, P < 0.001. The complete virological response rates were 73.95%, 66.09%, 67.19%, and 82.22%, 72.48%, and 70.49%, respectively. The incidence rates of low-level viremia were 16.67%, 21.70%, and 23.08%, while poor response rates were 1.11%, 3.67%, and 4.10%. ALT normalization rates were 64.00%, 63.89%, 67.96%, and 85.33%, 80.56%, 78.64%, respectively, and there was no statistically significant difference among the groups. LSM was significantly improved in patients treated with TAF for 48 weeks, P = 0.022. Serum phosphorus level gradually decreased with the prolongation of TDF treatment. The TAF treatment group had a good safety profile for kidney, bone, and phosphorus metabolism, with no dyslipidemia or related occurrences of risk. Conclusion:There are some differences in the therapeutic effects of first-line anti-HBV drugs. TAF has the lowest incidence of low-level viremia after 48 weeks of treatment and has a good safety profile in kidney, bone, and blood lipid metabolism.

Cow′s milk protein allergy (CMPA) is one of the most common presentations of food allergy seen in early childhood.It is an abnormal immune response caused by cow′s milk protein.CMPA can be clinically subdivided into either immediate-onset IgE mediated or delayed onset non-IgE mediated, or both.At present, concerns regarding the early and timely diagnosis of CMPA have been high-lighted over the years and there are many expert consensus on CMPA in China, but these consensus did not distinguish IgE mediated or non-IgE mediated CMPA.In view of the obvious clinical differences between the two type of CMPA and non-IgE mediated CMPA is more common in infancy, experts focus on pediatric gastroenterology, allergy/immunology, dermatology, nutrition and child healthcare convened by the Allergy Prevention and Control Professional Committee of Chinese Preventive Medicine Association present this guideline to help practitioners in primary care settings to early recognize and make suitable management of non-IgE mediated CMPA in China.The guideline incorporates the cutting-edge international guidance and the actual situation of Chinese children describing in detail the types, clinical features, diagnosis and nutritional intervention of non-IgE mediated CMPA.There are 42 recommendations in 7 categories in total referring to the common questions related to non-IgE mediated CMPA.

Genome mining for the search and discovery of two new globin-like enzymes, TriB fromFusarium poae and TutaA from Schizophyllum commne, are involved in the synthesis of two linear terpenes tricinonoic acid (1) and 2-butenedioic acid (3). Both in vivo heterologous biosynthesis and in vitro biochemical assays showed that these two enzymes catalyzed the C-C double bond cleavage of a cyclic sesquiterpene precursor (-)-germacrene D (7) and a linear diterpene backbone schizostain (2), respectively. Our work presents an unusual formation mechanism of linear terpenes from fungi and expands the functional skills of globin-like enzymes in the synthesis of terpene compounds.

Objective:To investigate the application value of Hisense computer-assisted surgery system (CAS) three-dimensional reconstruction in the precision treatment of pediatric liver tumors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 82 children with liver tumors who were admitted to Affiliated Hospital of Qingdao University from January 2013 to September 2021 were collected. There were 39 males and 43 females, aged 13(19)months. Children underwent upper abdominal dynamic enhanced computed tomography (CT) examination, and three-dimensional reconstruction was performed on CT images of arterial, equili-brium and venous phases with Hisense CAS. Surgical feasibility and scheme were evaluated and conducted based on the results of upper abdominal dynamic enhanced CT examination, and then revised according to three-dimensional reconstruction results of Hisense CAS. Observation indicators: (1) comparison of surgical scheme between two-dimensional enhanced CT images and three-dimensional reconstruction results of Hisense CAS; (2) intraoperative and postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination to detect postoperative compli-cations and residual liver compensation up to November 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(IQR) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Comparison of surgical scheme between two-dimensional CT images and three-dimensional reconstruction results of Hisense CAS. ① Based on the two-dimensional CT images, 42 cases of 82 children could undergo one-stage resection and 40 children could not. However, based on the three-dimensional reconstruction results of Hisense CAS, 48 cases of 82 children could undergo one-stage resection and 34 children could not. There were 6 children with one-stage resection feasibility based on the three-dimensional reconstruction results of Hisense CAS rather than the two-dimensional CT images. For the 34 children undergoing chemotherapy firstly, 31 cases had surgical feasibility after chemotherapy based on the two-dimensional CT images and 3 cases could not undergo surgery because of unapparent tumor regression or tumor surrounding impor-tant vessels. However, the 34 children had surgical feasibility after chemotherapy based on the three-dimensional reconstruction results of Hisense CAS. The revision rate of surgical feasibility was 11.0%(9/82) for the 82 children. ② Based on the two-dimensional CT images, 15 cases of 82 children underwent liver left lobectomy, 21 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 13 cases underwent extended left hemihepatectomy, 23 cases underwent extended right hemihepatectomy, 3 cases underwent segmental hepatectomy. However, based on the three-dimensional reconstruction results of Hisense CAS, 20 cases of 82 children underwent liver left lobectomy, 29 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 7 cases underwent extended left hemihepatectomy, 14 cases underwent extended right hemihepatectomy, 5 cases underwent segmental hepatectomy. The revision rate of surgical scheme was 36.6%(30/82) for the 82 children. (2) Intraoperative and postoperative situations. The operation time, volume of intraoperative blood loss, duration of postoperative hospital stay of the 82 children were (182±18)minutes, 20(10)mL, (10.2±1.9)days, respectively. (3) Follow-up. All the 82 children were followed up for 10 (range, 2?18)months. There was no obvious complication occurred to the 82 children after surgery, and the residual liver can satisfy the liver compensation of body. All the children survived well.Conclusion:Three-dimensional reconstruction of Hisense CAS is conducive to judging the surgical feasibility and formulation of accurate surgical plan of children with liver tumors.
