ObjectiveTo investigate the therapeutic effects and mechanism of decoctions from four kinds of processed products of Aconiti Radix Lateralis Praeparata(ARLP) in deficiency-cold syndrome. MethodsA total of 36 SD rats were randomly divided into the control group, model group, Shengfupian(SFP) group, Paofuzi(PFZ) group, Heishunpian(HSP) group and Paofupian(PFP) group with 6 rats in each group. Except for the control group, rats in other groups were administered hydrocortisone sodium succinate via intramuscular injection to induce a cold deficiency syndrome model. After 14 consecutive days, each ARLP decoction pieces was administered via continuous gastric lavage at a dose of 12 g·kg-1·d-1 for 7 d, while the control and model groups received an equivalent volume of physiological saline. After the end of administration, body weight, spleen weight and thymus weight were measured for calculating the spleen and thymus indexes. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of adrenal tissue. The fully automatic biochemistry analyzer was used to measure the total cholesterol(TC), triglyceride(TG), lactic dehydrogenase(LDH) and lactate(LAC) levels in serum. Enzyme-linked immunosorbent assay(ELISA) was employed to measure the contents of 17-hydroxycorticosteroid(17-OHCS), cortisol(CORT), triiodothyronine(T3), thyroxine(T4), thyrotropin(TSH), immunoglobulin(Ig) M, IgG, cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP). Western blot was used to measure the protein expression levels of protein kinase A(PKA), cAMP response element-binding protein(CREB), silent information regulator 1(Sirt1) and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α). And high performance liquid chromatography(HPLC) was used to determine the content of major alkaloids, followed by Pearson correlation analysis with pharmacodynamic indicators. ResultsAfter modeling, compare with the control group, the model rats exhibited symptoms such as lethargy and loose stools, mild abnormalities were observed in adrenal tissue structure, and both spleen and thymus indices were significantly reduced(P<0.01). Thyroid, adrenal and immune system functions were suppressed, with decreased serum cAMP level and significantly elevated cGMP level(P<0.01). Compared with the model group, the adrenal injury by hydrocortisone sodium succinate were repaired and the spleen index were increased significantly in all four ARLP groups(P<0.05, P<0.01). The thymus index in SFP and PFZ groups were increased significantly(P<0.05). The contents of T3, TSH, 17-OHCS and CORT were increased significantly in SFP and PFZ groups(P<0.05). In addition, the content of IgG in SFP, PFZ and PFP groups were increased significantly(P<0.01), while the content of IgM in PFZ and HSP groups were also increased significantly(P<0.05). Regarding the cyclic nucleotide system, PFZ significantly elevated cAMP level while reducing cGMP level(P<0.05), exhibiting the most pronounced effect among the four decoction pieces. For energy metabolism indicators, PFZ significantly improved abnormal markers including TC, TG, LDH, and LAC(P<0.05). HSP showed marked improvement effects on TG, LDH, and LAC(P<0.05). Both PFZ and SFP significantly elevated the expression levels of PKA, CREB, Sirt1, and PGC-1α proteins(P<0.01). Additionally, the diester alkaloids in ARLP showed a strong positive correlation with TG, IgG, and CORT, a strong negative correlation with LAC, a moderate positive correlation with T4, and moderate negative correlations with cAMP and spleen index. Monomeric alkaloids showed strong positive correlations with TG and IgG, strong negative correlations with LAC, moderate positive correlations with CORT and T4, and moderate negative correlations with cAMP and spleen index. However, the content of water-soluble alkaloids showed strong positive correlations with TC, LDH, 17-OHCS, T3, TSH, and thymus index, moderate positive correlations with cAMP, CORT, T4, and spleen index, and moderate negative correlation with cGMP. ConclusionAmong different processed ARLP decoction pieces, PFZ processed according to ZHANG Zhongjing's method exhibits the most potent warming and cold-dispelling effects. Its pharmacological actions are mediated through regulating the thyroid, adrenal, immune, cyclic nucleotide systems, and material-energy metabolism pathways. Among these, water-soluble alkaloids show strong or moderate correlations with more indicators of deficiency-cold syndrome and exhibit the highest content in PFZ. Therefore, PFZ processed according to ZHANG Zhongjing's method may exert its warming and cold-dispelling effects through water-soluble alkaloids.

Objective:To analyze the current status of red blood cell transfusion in very preterm infants (VPI) (gestational age at birth <32 weeks) from Chinese Neonatal Network (CHNN) in 2022.Methods:This cross-sectional study was based on the CHNN VPI cohort. It included 6 985 VPI admitted to CHNN 89 participating centers within 24 hours after birth in 2022. VPI with major congenital anomalies or those transferred to non-CHNN centers for treatment or discharged against medical advice were excluded. VPI were categorized based on whether they received red blood cell transfusions, their gestational age at birth, the type of respiratory support received during transfusion, and whether the pre-transfusion hemoglobin levels exceeded the thresholds. General characteristics, red blood cell transfusion rates, number of transfusions, timing of the first transfusion, and pre-transfusion hemoglobin levels were compared among different groups. The incidence of adverse outcomes between the group of VPI who received transfusions above the threshold and those who received transfusions below the threshold were compared. Comparison among different groups was conducted using χ2 tests, Kruskal-Wallis H tests, Mann-Whitney U test, and so on. Trends by gestational age at birth were evaluated by Cochran-Armitage tests and Jonckheere-Terpstra tests for trend. Results:Among the 6 985 VPI, 3 865 cases(55.3%) were male, with a gestational age at birth of 30.0 (28.6, 31.0) weeks and a birth weight of (1 302±321) g. Overall, 3 617 cases (51.8%) received red blood cell transfusion, while 3 368 cases (48.2%) did not. The red blood cell transfusion rate was 51.8% (3 617/6 985), with rates of 77.7% (893/1 150) for those born before 28 weeks gestational age and 46.7% (2 724/5 835) for those born between 28 and 31 weeks gestational age. A total of 9 616 times red blood cell transfusions were administered to 3 617 VPI, with 632 times missing pre-transfusion hemoglobin data, and 8 984 times included in the analysis. Of the red blood cell transfusions, 25.6% (2 459/9 616) were administered when invasive respiratory support was required, 51.3% (4 934/9 616) were receiving non-invasive respiratory support, while 23.1% (2 223/9, 616) were given when no respiratory support was needed. Compared to the non-transfusion group, the red blood cell transfusion group had a higher rate of pregnancy-induced hypertension in mothers, lower rates of born via cesarean section and mother′s antenatal steroid administration, smaller gestational age, lower birth weight, a higher proportion of small-for-gestational-age, multiple births, and proportions of Apgar score at the 5 th minute after birth ≤3 (all P<0.05). They were also less likely to be female, born in hospital or undergo delayed cord clamping (all P<0.01). Additionally, higher transport risk index of physiologic stability score at admission were observed in the red blood cell transfusion group ( P<0.001). The number of red blood cell transfusion was 2 (1, 3) times, with the first transfusion occurring at an age of 18 (8, 29) days, and a pre-transfusion hemoglobin level of 97 (86, 109) g/L. For VPI ≤7 days of age, the pre-transfusion hemoglobin levels for invasive respiratory support, non-invasive respiratory support, or no respiratory support, respectively, with no statistically significant differences between groups ( H=5.59, P=0.061). For VPI aged 8 to 21 days and≥22 days, the levels with statistically differences between groups (both P<0.01). Red blood cell transfusions above recommended thresholds were observed in all respiratory support categories at different stages of life, with the highest prevalence in infants aged 8 to 21 days and≥22 days who did not require respiratory support, at 90.1% (264/273) and 91.1%(1 578/1 732), respectively. The rate of necrotizing enterocolitis was higher in the above-threshold group ( χ2=10.59, P=0.001), and the duration of hospital stay was longer in the above-threshold group ( Z=4.67, P<0.001) compared to the below-threshold group. Conclusions:In 2022, the red blood cell transfusion rate was relatively high among VPI from CHNN. Pre-transfusion hemoglobin levels frequently exceeded recommended transfusion thresholds.

ObjectiveTo explore the current situation of adverse medical behaviors in oncology patients and propose corresponding countermeasures to reduce the incidence of adverse medical behaviors in oncology patients, standardize their diagnosis and treatment order, and ensure the quality and safety of medical care. MethodsUsing the purposive sampling method, 16 oncology patients and caregivers from 3 communities in a city were selected for semi-structured and in-depth qualitative interviews from October to December 2023. Nvivo 12.0 software was used for data transcription and thematic analysis. ResultsThree themes were extracted. First, the adverse medical behaviors in oncology patients included overtreatment, non-standardized medication, and inaccurate recommendations of exorbitant examination items. Second, the influencing factors of adverse medical behaviors in oncology patients included limitations of the medical system and policy issues, difficulty in defending the rights of patients in a vulnerable position, as well as inadequacy of related ethical supervision and laws and regulations. Third, the countermeasures for adverse medical behaviours in cancer patients mainly encompassed improving the construction of medical systems and policies, optimizing the allocation of medical resources, enhancing the medical ethical literacy of medical personnel, standardizing the professional behaviour of medical personnel, strengthening medical ethical education for patients and enhancing their awareness of the protection of rights and interests, as well as strengthening ethical supervision and evaluation. ConclusionThe adverse medical behaviors in oncology patients are affected by tripartite factors, including medical staff, patients, and the system. The government, medical institutions, medical personnel, and patients should all adopt targeted countermeasures to deal with adverse medical behaviours, thus regulating diagnosis and treatment orders and ensuring the quality and safety of medical care.

ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer (CRC) and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit, followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group, low-dose Xianlian Jiedu prescription (XLJDP-L) group (6.45 g·kg-1·d-1), medium-dose Xianlian Jiedu prescription (XLJDP-M) group (12.9 g·kg-1·d-1), high-dose Xianlian Jiedu prescription (XLJDP-H) group (25.8 g·kg-1·d-1), and 5-fluorouracil (5-FU) group (1×10-3 g·kg-1·d-1). The mice were euthanized after 14 days of continuous intervention, and recurrent tumor tissue was harvested. Hematoxylin and eosin (HE) staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry (IHC) was employed to assess the expression of proliferating cell nuclear antigen (Ki67), vascular endothelial growth factor (VEGF), and platelet-endothelial cell adhesion molecule (CD31) in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 (ANG-2), VEGF, phosphorylated-protein kinase B (p-Akt), protein kinase B (Akt), phosphorylated-phosphatidylinositol 3-kinase (p-PI3K), and phosphatidylinositol 3-kinase (PI3K) in recurrent tumor tissue. ResultsBefore treatment, there were no statistical differences in tumor volume, tumor weight, and body mass among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group, indicating model stability. After treatment, compared with those in the model group, the tumor volume and tumor weight in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01), showing dose dependency. Meanwhile, there were no significant differences in body weight among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group, tumor tissue in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group had loosely arranged cells, increased intercellular spaces, small and shriveled nuclei, light staining, fewer mitotic figures and atypical nuclei, and increased necrotic areas. IHC showed that compared with those of the model group, the positive rates of Ki67, VEGF, and CD31 in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01) in a dose-dependent manner. Western blot results showed that compared with those of the model group, the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly downregulated (P<0.05, P<0.01), and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner (P<0.05, P<0.01). ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2, VEGF, and CD31.

Collagen is a major structural protein in the matrix of animal cells and the most widely distributed and abundant functional protein in mammals. Collagen’s good biocompatibility, biodegradability and biological activity make it a very valuable biomaterial. According to the source of collagen, it can be broadly categorized into two types: one is animal collagen; the other is recombinant collagen. Animal collagen is mainly extracted and purified from animal connective tissues by chemical methods, such as acid, alkali and enzyme methods, etc. Recombinant collagen refers to collagen produced by gene splicing technology, where the amino acid sequence is first designed and improved according to one’s own needs, and the gene sequence of improved recombinant collagen is highly consistent with that of human beings, and then the designed gene sequence is cloned into the appropriate vector, and then transferred to the appropriate expression vector. The designed gene sequence is cloned into a suitable vector, and then transferred to a suitable expression system for full expression, and finally the target protein is obtained by extraction and purification technology. Recombinant collagen has excellent histocompatibility and water solubility, can be directly absorbed by the human body and participate in the construction of collagen, remodeling of the extracellular matrix, cell growth, wound healing and site filling, etc., which has demonstrated significant effects, and has become the focus of the development of modern biomedical materials. This paper firstly elaborates the structure, type, and tissue distribution of human collagen, as well as the associated genetic diseases of different types of collagen, then introduces the specific process of producing animal source collagen and recombinant collagen, explains the advantages of recombinant collagen production method, and then introduces the various systems of expressing recombinant collagen, as well as their advantages and disadvantages, and finally briefly introduces the application of animal collagen, focusing on the use of animal collagen in the development of biopharmaceutical materials. In terms of application, it focuses on the use of animal disease models exploring the application effects of recombinant collagen in wound hemostasis, wound repair, corneal therapy, female pelvic floor dysfunction (FPFD), vaginal atrophy (VA) and vaginal dryness, thin endometritis (TE), chronic endometritis (CE), bone tissue regeneration in vivo, cardiovascular diseases, breast cancer (BC) and anti-aging. The mechanism of action of recombinant collagen in the treatment of FPFD and CE was introduced, and the clinical application and curative effect of recombinant collagen in skin burn, skin wound, dermatitis, acne and menopausal urogenital syndrome (GSM) were summarized. From the exploratory studies and clinical applications, it is evident that recombinant collagen has demonstrated surprising effects in the treatment of all types of diseases, such as reducing inflammation, promoting cell proliferation, migration and adhesion, increasing collagen deposition, and remodeling the extracellular matrix. At the end of the review, the challenges faced by recombinant collagen are summarized: to develop new recombinant collagen types and dosage forms, to explore the mechanism of action of recombinant collagen, and to provide an outlook for the future development and application of recombinant collagen.

OBJECTIVE To establish fingerprint, chemical pattern recognition and multi-component quantification analysis of Sanzi powder, and evaluate its quality. METHODS HPLC method was adopted. The fingerprints of 15 batches of Sanzi powder were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). Cluster analysis, principal component analysis and orthogonal partial least squares-discriminant analysis were also conducted. The variable importance in projection (VIP) value greater than 1 was used as the index to screen the differential markers, and the contents of the differential markers were determined by the same HPLC method. RESULTS A total of 21 common peaks in the HPLC fingerprints of 15 batches of Sanzi powder were calibrated, and the similarities of them were 0.994- 0.999; 6 common peaks were identified, including gallic acid (peak 3), garminoside (peak 10), corilagin (peak 11), chebulinic acid (peak 16), ellagic acid (peak 18), crocin Ⅰ (peak 19). According to the results of cluster analysis, YKD2024LH005,No.YKD2023LH062) principal component analysis and orthogonal partial least squares-discriminant analysis, 15 batches of samples could be clustered into two categories: S1, S5, S7, S9, S14 were clustered into one category; S2-S4, S6, S8, S10-S13, S15 were clustered into one category. VIP values of 11 differential components such as corilagin, chebulinic acid and ellagic acid were higher than 1. Among 15 batches of samples, the contents of corilagin, chebulinic acid and ellagic acid ranged 2.667-5.152, 9.506- 13.522, 0.891-1.811 mg/g. CONCLUSIONS Established HPLC fingerprint and multi-component quantification analysis of Sanzi powder are rapid and simple, and can be used for quality evaluation of Sanzi powder by combining with chemical pattern recognition. Eleven components such as corilagin, chebulinic acid and ellagic acid are differential markers affecting the quality of Sanzi powder.
