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 explore the classification and influencing factors of family resilience and post-traumatic growth in patients with spinal tumor.Methods:A cross-sectional investigation was conducted among 219 inpatients with spinal tumor admitted from July 2021 to July 2022. The General Demographic Information questionnaire, Chinese-Family Resilience Assessment Scale, Posttraumatic Growth Inventory, Family Crisis-Oriented Personal Evaluation Scales (F-COPES), and Social Support Rating Scale (SSRS) were used in the study. The ordinal and multivariate logistic regression analyses was applied to identify the factors associated with the classification of family resilience and post-traumatic growth.Results:Of the 219 patients, there were 62 cases of primary spinal tumors (28.3%). According to the results of latent profile analysis, the respondents were classified into three categories by family resilience and post-traumatic growth, namely family difficulty-resistant type ( n=38, 17.4%), general resilience-struggle type ( n=99, 45.2%) and family adaptation-growth type ( n=82, 37.4%). There were significant differences in occupational status, commitment to housework, family atmosphere( χ2=10.75, P=0.025; χ2=6.95, P=0.031; χ2=11.37, P=0.017), and total score of F-COPES and SSRS ( F=25.95, P<0.001; F=19.06, P<0.001)among three groups. Ordinal and multivariate logisitc regression analyses showed that retirement ( OR=2.928, 95% CI:1.098-7.808, P<0.05), family coping ( OR=1.113, 95% CI:1.063-1.165, P<0.05), and social support ( OR=1.226, 95% CI:1.103-1.362, P<0.05) were independently associated with family resilience and post-traumatic growth in patients with spinal tumor. Conclusion:Patients with spinal tumor have significant differences in characteristics by family resilience and post-traumatic growth. As a result, more targeted interventions should be provided for different categories of spinal tumor patients in the future.

Chronic myeloid leukemia (CML) is a slowly progressing hematopoietic cell disorder. Sphingosine kinase 1 (SPHK1) plays established roles in tumor initiation, progression, and chemotherapy resistance in a wide range of cancers, including leukemia.However, small-molecule inhibitors targeting SPHK1 in CML still need to be developed. This study revealed the role of SPHK1 in CML and investigated the potential anti-leukemic activity of hirsuteine (HST), an indole alkaloid obtained from the oriental plant Uncaria rhynchophylla, in CML cells. These results suggest that SPHK1 is highly expressed in CML cells and that overexpression of SPHK1 represents poor clinical outcomes in CML patients. HST exposure led to G2/M phase arrest, cellular apoptosis, and downregulation of Cyclin B1 and CDC2 and cleavage of Caspase 3 and PARP in CML cells. HST shifted sphingolipid rheostat from sphingosine 1-phosphate (S1P) towards the ceramide coupled with a marked inhibition of SPHK1. Mechanistically, HST significantly blocked SPHK1/S1P/S1PR1 and BCR-ABL/PI3K/Akt pathways. In addition, HST can be docked with residues of SPHK1 and shifts the SPHK1 melting curve, indicating the potential protein-ligand interactions between SPHK1 and HST in both CML cells. SPHK1 overexpression impaired apoptosis and proliferation of CML cells induced by HST alone. These results suggest that HST, which may serve as a novel and specific SPHK1 inhibitor, exerts anti-leukemic activity by inhibiting the SPHK1/S1P/ S1PR1 and BCR-ABL/PI3K/Akt pathways in CML cells, thus conferring HST as a promising anti-leukemic drug for CML therapy in the future.

Objective:
To investigate the sonographic features of appendicitis in preterm infants.
Methods:
A total of 28 cases of premature infants with acute appendicitis diagnosed by bedside abdominal ultrasound in the First Hospital of Jilin University from November 2012 to January 2019 were recruited. Basic clinical information, abdominal ultrasound images, surgical results, management and outcomes were collected and analyzed. Descriptive statistical methods were used for data analysis.
Results:
Among the 28 cases, 21 (75.0%) were males and seven (25.0%) were females. All of them were diagnosed as having acute appendicitis with perforation according to the bedside ultrasound. Five (17.8%) presented direct signs of appendicitis, i.e. partial structure of the appendix and perforation site. The other 23 (82.2%) showed indirect signs, including heterogeneous echotexture or hypoechoic patterns between the liver and right kidney in six cases, heterogeneously hypoechoic areas between the bowels in the right lower abdomen in seven cases, and dissociative effusion between the bowels in the right lower abdomen with poor sound transmission and disorder of surrounding intestinal structure in ten cases. Twenty-one out of the 28 cases (75.0%) exhibited bowel wall thickening at right lower abdomen, absence of intestinal peristalsis and effusion echoes between the intestines with poor sound transmission. Emergent surgeries were performed and diagnoses of appendicitis with perforation were confirmed. All the 21 cases were discharged after full recovery. Seven cases (25.0%) showed confined cystic images and received conservative treatment. One of them developed adhesive intestinal obstruction during follow-ups and underwent surgical treatment, during which local formations of wrapping after appendiceal perforation and obstruction due to surrounding intestinal adhesion were observed. The other six cases recovered after conservative management with gradually reduced peritoneal effusion, normal omental echo patterns and improved inflammatory indicators and abdominal symptoms, and no ileus occurred during follow-ups after discharge.
Conclusions
Symptoms of appendicitis in preterm infants are non-specific, and perforation is more likely to be seen. Bedside ultrasonography mainly shows indirect signs of appendicitis, and direct signs in some infants. Bedside ultrasound can be an essential tool for the diagnosis of these conditions with high accuracy.
