ObjectiveTo explore the mechanism by which Xiaoyaosan regulates HPT axis dysfunction in the rat model with the syndrome of liver depression and spleen deficiency by observing its effect on the glycoprotein hormone α-subunit (CGA)/glutathione peroxidase 2 (GPX2)/thyroid-stimulating hormone β-subunit (TSHβ) pathway for thyroid hormone synthesis. MethodsSeventy-two male SD rats were randomized into six groups: normal, model, high-dose (16.7 g·kg-1), medium-dose (8.35 g·kg-1), and low-dose (4.175 g·kg-1) Xiaoyaosan, and fluoxetine (0.001 8 g·kg-1) groups, with 12 rats in each group. The rat model of liver depression and spleen deficiency was induced by chronic restraint stress for 21 days. The intervention groups were treated with Xiaoyaosan decoctions or fluoxetine suspension, respectively. After modeling, hematoxylin-eosin staining was employed to observe morphological changes in the thyroid and pituitary tissue of the rats. Serum levels of triiodothyronine (T3), tetraiodothyronine (T4), and thyroid-stimulating hormone (TSH) were measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of TSH receptor (TSHR) in the thyroid tissue, thyrotropin-releasing hormone receptor (TRHR) and TSHβ in the pituitary tissue, and thyrotropin-releasing hormone (TRH), CGA, GPX2, and TSHβ in the hypothalamic tissue. ResultsCompared with the normal group, the model group showed significant atrophy and irregularity of thyroid follicles, a marked reduction in colloid secretion, extensive vacuolar degeneration of adenocytes in the anterior pituitary, lowered serum levels of T3, T4, and TSH (P<0.01), and down-regulated mRNA and protein levels of TSHR in the thyroid tissue, TRHR and TSHβ in the pituitary tissue, and TRH, CGA, GPX2, and TSHβ in the hypothalamic tissue (P<0.01). Compared with the model group, high- and medium-dose Xiaoyaosan and fluoxetine alleviated the pathological changes in the thyroid and pituitary tissue, outperforming the low-dose Xiaoyaosan group. Moreover, they elevated the serum levels of T3, T4, and TSH (P<0.05, P<0.01). The serum TSH level was also elevated in the low-dose Xiaoyaosan group (P<0.05). The mRNA and protein levels of TSHR in the thyroid, TRHR and TSHβ in the pituitary, and TRH, CGA, GPX2, and TSHβ in the hypothalamus were up-regulated in the high- and medium-dose Xiaoyaosan groups (P<0.05, P<0.01). Additionally, the mRNA and protein levels of TSHβ in the hypothalamus were up-regulated in the low-dose Xiaoyaosan group (P<0.01). In the fluoxetine group, the mRNA and protein levels of TSHR in the thyroid, TRHR in the pituitary, and TRH, CGA, and GPX2 in the hypothalamus were up-regulated (P<0.05, P<0.01). ConclusionThe downregulation of CGA/GPX2/TSHβ pathway may be one of the biological mechanisms underlying HPT axis dysfunction in the rat model with the syndrome of liver depression and spleen deficiency. Xiaoyaosan may regulate the HPT axis dysfunction by up-regulating the CGA/GPX2/TSHβ pathway.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ(CaMKⅡ)/cAMP-response element binding protein (CREB) signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet, intraperitoneal injection of isoproterenol (ISO), and chronic unpredictable mild stress (CUMS). A total of 108 SD male rats were randomly divided into normal group, model group, high (23.4 g·kg-1), medium (11.7 g·kg-1), and low (5.85 g·kg-1) dose groups of modified Chaihu Shugansan, CaMKⅡ inhibitor (KN93) group, and KN93 + high, medium, and low dose groups of modified Chaihu Shugansan, with 12 rats in each group. From the first day of modeling to the end of modeling, drugs were administered once a day. In the seventh and eighth weeks, the KN93 group and the KN93 + high, medium, and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week, behavioral tests including sucrose preference, open field, and elevated plus maze were conducted. Electrocardiogram (ECG) lead Ⅱ changes were observed in each group of rats, and hematoxylin-eosin (HE) staining was performed to observe changes in heart tissue. Serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and lactate dehydrogenase (LDH) were measured by using an enzyme-labeled instrument. Creatine kinase (CK) and creatine kinase-MB (CK-MB) were detected by ultraviolet spectrophotometry, while serum monocyte chemoattractant protein-1 (MCP-1) was measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue, and Western blot was performed to assess protein expression of CaMKⅡ, phosphorylated (p)-CaMKⅡ, CREB, and p-CREB. ResultsCompared to the normal group, the model group showed significant reductions in sucrose preference rate, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01). The ECG showed ST-segment elevation, and HE staining showed serious degeneration of myocardial fibers, disordered arrangement, and infiltration of a large number of inflammatory cells. In addition, serum TC and LDL levels increased (P<0.01), and HDL level decreased (P<0.01). CK, CK-MB, LDH, and MCP-1 levels significantly increased (P<0.05, P<0.01). The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue (P<0.05, P<0.01), but those increased in the heart tissue (P<0.01). Compared to the model group, the high, medium, and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01), as well as decreased serum CK, CK-MB, LDH, and MCP-1 levels (P<0.05, P<0.01). KN93 also reduced ST-segment elevation, alleviated the degeneration degree of myocardial fibrosis, and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced (P<0.05, P<0.01). The KN93 + high, medium, and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression, possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway, with the high-dose modified Chaihu Shugansan showing the best effects.

Objective:To explore the application effect of 5E nursing guided by empowerment theory in patients undergoing liver cancer resection.Methods:Using the purposive sampling method, a total of 88 patients who underwent liver cancer resection surgery in Zhumadian Central Hospital from July 2020 to July 2022 were selected as the research objects. They were divided into the control group ( n=44) and the observation group ( n=44) by the random number table method. The control group was given 5E nursing, while the observation group was given 5E nursing guided by empowerment theory. The improvement of gastrointestinal function between the two groups was compared by the first anal defecation time, the first anal exhaust time and the recovery time of bowel sound. Visual Analogue Scale (VAS) was used to evaluate postoperative pain, General Self-Efficacy Scale (GSES) was used to evaluate self-efficacy, and hope level was assessed by Herth Hope Index (HHI). After treatment, the compliance and occurrence of digestive tract discomfort were compared between the two groups. Results:The first anal defecation time, first anal exhaust time and bowel sound recovery time in observation group were less than those in control group ( P<0.05). Postoperative pain score of observation group was lower than that of control group 48 hours after operation ( P<0.05). After nursing, the GSES, HHI and compliance scores of the observation group were higher than those of the control group ( P<0.05), and the incidence of gastrointestinal discomfort symptoms in the observation group was lower than that in the control group ( P<0.05) . Conclusions:The 5E nursing guided by empowerment theory can effectively improve the compliance, self-efficacy and hope level of liver cancer resection patients, reduce pain, promote postoperative recovery and reduce the incidence of gastrointestinal discomfort symptoms.

Objective:To explore the application effect of nursing intervention based on the information-motivation-behavioral skills (IMB) model in perioperative nursing of children undergoing concealed penis phalloplasty.Methods:Using the convenient sampling method, a total of 86 children who were admitted to and underwent concealed penis phalloplasty in Jiaxing Maternity and Child Health Care Hospital were selected as the research objects from January 2022 to January 2023. They were randomly divided into the observation group and the control group, with 43 cases in each group. The control group was treated with routine nursing mode, and the observation group was treated with IMB model nursing intervention based on routine nursing. The heart rate (HR) and mean arterial pressure (MAP) levels of children in the two groups were recorded at five time points, such as after preoperative visit (T 0), when leaving the preparation room period (T 1), before anesthesia induction (T 2), when leaving the anesthesia recovery room (T 3) and 24 h postoperative follow-up (T 4). The children were evaluated using Children's Emotional Adjustment Scale Preschool Version (CEAS-P), Modified Yale Preoperative Anxiety Scale (m-YPAS), the Induction Compliance Checklist (ICC) and Pediatric Anesthesia Emergence Delirium (PAED) . Results:After intervention, the CEAS-P scores in the observation group were higher than those in the control group, while the m-YPAS, ICC and PAED scores were lower than those in the control group, and the differences were statistically significant (all P<0.01). There were statistically significant differences in HR and MAP levels of children undergoing concealed penis phalloplasty between the two groups at different time points ( P<0.01). HR and MAP levels at T 0, T 1, T 2, T 3 and T 4 in observation group were lower than those in control group, and the differences were statistically significant (all P<0.05). There was statistically significant differences in the interaction between nursing intervention and HR and MAP over time ( P<0.01) . Conclusions:Nursing intervention based on the IMB model can effectively relieve the psychological anxiety of children with concealed penis phalloplasty in perioperative period and improve surgical safety.

A 31-year-old man sought medical evaluation for a 2-year history of edema and proteinuria, with prior pathology suggesting atypical membranous nephropathy (MN). Despite treatment with a combination of steroids, calcineurin inhibitors, and four courses of rituximab (1 g, intravenous injection), the patient′s nephrotic syndrome showed no relief (24 h urine protein peaked at 31.18 g/d), indicating refractory nephrotic syndrome. Later in the disease course, a sudden surge of creatinine level (322.5 μmol/L) prompted a renal biopsy, which revealed concurrent acute interstitial nephritis. Further treatment involving steroids, cyclophosphamide, and a fifth rituximab infusion (1 g, intravenous injection) resulted in improvement in renal function (serum creatinine: 322.5?147 μmol/L), but the MN failed to achieve partial relief. Subsequent treatment with the novel humanized CD20 monoclonal antibody obinutuzumab (1 g, intravenous injection) was initiated. In the latest follow-up, anti-phospholipase-A2-receptor antibody (PLA2R) antibody were negative, B cells were eliminated, serum albumin was 36 g/L, urine protein-to-creatinine ratio was 4 810 mg/g, and serum creatinine was 162 μmol/L. This case underscores the potential efficacy of obinutuzumab in refractory MN. For advanced MN cases, prompt identification of the cause of acute kidney injury is crucial, emphasizing the need for targeted interventions to potentially stall renal function decline.
