ObjectiveTo investigate the effects of Huangqi Jianzhongtang （HQJZ） on macrophage polarization and fat consumption in cancer cachexia （CC） mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） was used to control the quality of HQJZ. （1） In vitro experiment： HQJZ-containing serum was prepared， and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages （RAW264.7） were cultured and randomly divided into six groups， including a blank group， a classically activated macrophages （M1） group， an alternatively activated macrophages （M2） group， a HQJZ + blank group， a HQJZ+M1 group， and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86， inducible nitric oxide synthase （iNOS）， CD206， and arginase-1 （Arg1） was detected by real-time quantitative polymerase chain reaction （Real-time PCR ）. （2） In vivo experiment： Thirty-two BALB/c mice were randomly divided into a control group， a model group， a medroxyprogesterone acetate （MPA） group， and a HQJZ group. Except for the control group， the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA （0.13 g·kg^-1·d^-1） or HQJZ （13.13 g·kg^-1·d^-1） by gavage， respectively， while mice in the control and model groups were given an equal volume of saline by gavage， with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers （iNOS， Arg1， CD86， CD206） and fat browning-related genes uncoupling protein 1 （UCP1） and peroxisome proliferator-activated receptor γ （PPARγ） in epididymal adipose tissue. Western blot （WB） was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography （micro-CT） was used to measure residual fat volume， and hematoxylin-eosin （HE） staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro， the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that， compared with the blank group， Arg1 expression decreased in the HQJZ+blank group （P<0.05）， CD206 showed a downward trend without statistical significance， while iNOS and CD86 expression were significantly increased （P<0.05）. Compared with the M1 group， Arg1 and CD206 expression decreased in the HQJZ+M1 group （P<0.05）. Compared with the M2 group， CD206 expression decreased in the HQJZ+M2 group （P<0.05）， CD86 expression increased significantly （P<0.01）. In vivo， Real-time PCR results showed that， compared with the control group， CD86 and CD206 expression levels were significantly increased in the model group （P<0.01）. Compared with the model group， CD206 expression in the MPA group was significantly decreased （P<0.01）. In the HQJZ group， CD206 was significantly decreased （P<0.01）. WB results showed that， compared with the model group， protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group （P<0.05， P<0.01）. micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group （P<0.05）. HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group （P<0.05）. ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization， thereby delaying fat consumption in CC mice.

Objective:To evaluate the effect of different interventions in post-percutaneous coronary intervention (PCI) patients with kinesiophobia using network Meta-analysis.Methods:Computerized search of randomized controlled trials and quasi-experiment related to kinesiophobia interventions for post-PCI patients in WanFang database, China National Knowledge Infrastructure, China Biology Medicine, VIP database, Web of Science, PubMed, Cochrane Library and Embase was conducted with a time frame of searching from the establishment of the library to August 3, 2023. Literature screening, data extraction and literature quality evaluation were carried out independently by two researchers. Network Meta-analysis was performed using Stata 17.0 software.Results:A total of 13 literatures were included, including 9 randomized controlled trials and 4 quasi-experiments.Network Meta-analysis showed that cognitive behavioral therapy ( SMD = -4.08, 95% CI -6.49 --1.67), cognitive behavioral therapy combined with cardiac rehabilitation ( SMD = - 3.02, 95% CI -5.43 -- 0.61), dual heart medical intervention ( SMD = - 2.48, 95% , - 4.87 - - 0.09) can reduce the level of exercise fear in patients after PCI, and the difference were statistically significant compared with routine nursing (all P< 0.05). Ranked probability plots showed that the effects of the nine interventions in reducing kinesiophobia in post-PCI patients were cognitive behavioral therapy, cognitive behavioral therapy combined with cardiac rehabilitation, adaptive leadership theory-based intervention, dual heart medical intervention, COX health behavior interaction model, health education based on the behavioral change wheel, graded exposure therapy, mindfulness intervention, and high-intensity interval training in descending order of effectiveness. Conclusions:Cognitive behavioral therapy was the most effective intervention for kinesiophobia in post-PCI patients, but more high-quality randomized controlled trials are needed to further verify this conclusion.

Objective:To investigate the predictive value of differential distribution of peripheral lymphocyte subsets before and after the first 131I treatment on the therapeutic response to 131I treatment in patients with papillary thyroid cancer (PTC). Methods:A retrospective study was conducted on 46 PTC patients (16 males, 30 females, age 20-77 years) who underwent total thyroidectomy and received 131I treatment between January 2021 and August 2021 in First Hospital of Shanxi Medical University. Peripheral blood lymphocyte subsets (T, B, CD4 + T, CD8 + T, natural killer (NK), helper T (Th)1, Th2, Th17, and regulatory T (Treg) cells) were measured 1-2 d before and 30 d after 131I treatment. Based on serological and imaging evidence, therapeutic response at 6-12 months post- 131I therapy was categorized as either excellent response (ER) or non-excellent response (NER). Differences of preablative stimulated thyroglobulin (psTg) and clinical baseline characteristics between two groups were assessed by using independent-sample t test, paired t test, or Mann-Whitney U test. Predictive value of lymphocyte subsets before and after 131I treatment for therapeutic response was assessed through logistic regression analysis, ROC curve analysis, and decision curve analysis (DCA). Results:In ER group ( n=33) and NER group ( n=13), most lymphocyte subsets showed different degrees of reduction 30 d after 131I treatment compared to before 131I treatment, such as T, B, CD4 + T and Th1 cells in ER group, as well as T, B, CD4 + T, Th1, Th2, Th17, and Treg cells in NER group ( t values: 2.41-9.57, all P<0.05). Before 131I treatment, NER group had significantly higher levels of psTg, Th2, Th17, and Treg cells compared to the ER group ( t values: from -3.32 to -2.48, U=29.00, all P<0.05). After 131I treatment, most of lymphocyte subsets in NER group (T, B, CD4 + T, CD8 + T, Th1 and Treg cells) showed higher trend than those in ER group but without statistical significances ( t values: from -1.12 to -0.06, all P>0.05). Th2 cells before 131I treatment (odds ratio ( OR)=25.00, 95% CI: 1.36-459.10, P=0.030) was identified as a risk factor for NER. ROC curve analysis indicated that AUCs of psTg and Th2 cells for predicting therapeutic response were 0.932 and 0.790, respectively, which was 0.958 for the combined psTg and Th2 cells. DCA showed that within the threshold probability range of 10%-60%, the curves for psTg, Th2 cells, and the combined psTg and Th2 cells were all higher than the extreme curve, suggesting good effect. Conclusions:Most lymphocyte subsets decrease to varying degrees, and NER group shows a significant decrease 30 d after 131I treatment. Th2 cells may be a risk factor for poor response to 131I treatment, providing a certain value in predicting the therapeutic response to 131I treatment.

Alzheimer's disease （AD） is a deleterious neurodegenerative disorder， which has become a significant public health concern and economic burden. The pathogenesis of AD is complex and involves several hypotheses such as amyloid β-protein （Aβ） deposition， Tau protein hyperphosphorylation， oxidative stress， and inflammation. There is an urgent need for a holism-based comprehensive intervention with multi-pathway， multi-level， and multi-target characteristics， which demonstrates the unique advantage of traditional Chinese medicine （TCM）. Therefore， it is of great significance to conduct and promote research on TCM treatment of AD. Danggui Shaoyaosan （DSS） from the Synopsis of Golden Chamber （《金匮要略》） by ZHANG Zhongjing （150 AD-219 AD） was originally designed for reliving gynecological ailments. It is a classic TCM formula that modulates liver and spleen and dispels blood stasis and water retention. Since the late 1980s when Japanese researchers reported its therapeutic effect on AD， it has been widely used in the clinic with clear effects. The elucidation of the mechanism of this formula helps exert its effects. Hereby， this paper reviewed relative research progress and made an analysis in terms of attenuating aberrant accumulation of Aβ and hyperphosphorylated Tau protein， anti-inflammatory and antioxidant activities， mediating neurotransmitters， ameliorating lipid metabolism， modulating gut microbiota， reduced neuron apoptosis， decreasing intracellular Ca²⁺ overloading， and increasing the expression of estradiol. This paper is expected to provide references for understanding the scientific connotation of DDS in the treatment of AD and lay a solid foundation for further investigation.

ObjectiveTo investigate the mechanism of Danggui Shaoyaosan （DSS） in the improvement of the cognitive ability of SAMP8 mice with Alzheimer's disease （AD） via regulating the ubiquitin-proteasome pathway （UPP）. MethodFifteen SAMR1 mice were used as a normal group， and 60 SAMP8 mice were randomly divided into a model group and DSS high， medium， and low-dose groups （57.6， 28.8， and 14.4 g·kg^-1·d^-1）， with 15 mice in each group. Intragastric administration was conducted for eight continuous weeks. Place navigation and spatial capacity were evaluated by Morris water maze. Pathological structure changes in neurons in the hippocampal CA1 area was detected by hematoxylin-eosin （HE） staining. The protein expression levels of hippocampal β-amyloid protein（Aβ） and phosphorylation（p）-Tau were determined by immunohistochemical staining （IHC） and enzyme-linked immunosorbent assay （ELISA）， and the mRNA and protein expression levels of hippocampal ubiquitin （Ub）， ubiquitin ligase E3 （E3）， 26S proteasome， ubiquitin carboxyl terminal hydrolase-1 （UCHL1）， and UCHL3 were determined by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultAs compared with the normal group， the escape latency was prolonged in the model group （P<0.05） with the reduced number of crossing platform quadrants and time ratio in the platform quadrant （P<0.05）. The model group decreased neurons and condensed cell bodies in the CA1 area， and increased β-amyloid precursor protein （β-APP） and p-Tau positive cells （P<0.05）. In the model group， the protein expression levels of Aβ and p-Tau were increased （P<0.05）， the mRNA and protein expression levels of Ub were increased （P<0.05）， and the mRNA and protein expression levels of E3， 26S proteasome， UCHL1， and UCHL3 were decreased （P<0.05）. As compared with the model group， the escape latency was shortened in the DSS high and medium-dose groups （P<0.05） with an increased number of crossing platform quadrants and residence time ratio （P<0.05）. The pathological changes in CA1 of each DSS group were significantly improved， and the number of β-APP positive staining cells decreased （P<0.05）. The number of p-Tau positive staining cells decreased in the DDS medium and low-dose groups （P<0.05）. The protein expression levels of Aβ and p-Tau in each DDS group decreased （P<0.05）， and the mRNA expression level of Ub in each group decreased （P <0.05）. The mRNA expression levels of 26S， E3， and UCHL3 in the DDS high and medium-dose groups increased （P<0.05）， and the mRNA expression level of UCHL1 in the DDS medium-dose group increased （P<0.05）. The protein expression level of Ub in each DDS group decreased， and the protein expression levels of 26S， E3， UCHL1+3 in the DDS high and medium-dose groups increased （P<0.05）. ConclusionDSS can improve the cognitive ability of SAMP8 mice， and its mechanism may be related to the reduction of the abnormal deposition of Aβ and p-Tau via decreasing the expression of Ub and increasing that of E3， 26S， UCHL1， and UCHL3 in the UPP.

ObjectiveTo investigate the protective effect of Danggui Shaoyaosan （DSS）-contained serum on β-amyloid （Aβ）_1-40-injured rat adrenal pheochromocytoma PC12 cells and its mechanism in regulating ubiquitin-proteasome pathway （UPP）. MethodAβ_1-40 was used to intervene PC12 cells to prepare the cell models of Alzheimer's disease （AD）， and the experiment was divided into the blank， model， and DSS-contained serum high， medium， and low-dose groups （10%， 5%， and 2.5%）. Cell viability and apoptosis were detected using cell counting kit-8 （CCK-8） method and flow cytometry， respectively. The content of Aβ and p-Tau protein was determined by enzyme-linked immunosorbent assay （ELISA）. The ubiquitin （Ub）， ubiquitin ligase E3 （E3）， 26S proteasome， ubiquitin carboxyl terminal hydrolase1 （UCHL1）， and UCHL3 protein expressions of UPP were displayed using immunofluorescence cytochemistry （ICC）， and the mRNA and protein expression levels of Ub， E3-parkin， 26S， UCHL1， and UCHL3 were determined by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultThe data of the CCK8 experiment verified that 5 μmol·L^-1 and 48 hours were the optimal conditions for modeling Aβ_1-40-injured PC12 cells. As compared with the blank group， the cell viability rate in the model group decreased （P<0.05） with an increased apoptosis rate （P<0.05）， the content of Aβ and p-Tau contents was elevated （P<0.05）， the mRNA and protein expression levels of Ub increased， and the mRNA and protein expression levels of 26S， E3， and UCHL1+3 decreased （P<0.05）. As compared with the model group， the cell viability rate in the DSS-contained medium-dose group increased （P<0.05）， whereas the apoptosis rate in each DSS-contained group decreased （P<0.05）. The content of Aβ in each DDS-contained group decreased （P<0.05）， and the content of p-Tau in the DDS-contained high and medium-dose groups decreased （P<0.05）. The mRNA expression level of Ub decreased， and that of 26S increased in each DDS-contained group （P<0.05）. The mRNA expression level of UCHL1 in the DDS-contained medium-dose group increased （P<0.05）， and the mRNA expression levels of E3 and UCHL 3 in the DDS-contained high and medium-dose groups increased （P<0.05）. The protein expression level of Ub in each DDS-contained group decreased， and the protein expression levels of 26S， E3， and UCHL1+3 in the DDS high and medium-dose groups increased. The DSS-contained serum medium-dose group exerted the optimal effect. ConclusionDSS-contained serum can increase cell viability rate， reduce cell apoptosis rate， eliminate Aβ and p-Tau protein deposits， and exert protective effects on Aβ_1-40-injured PC12 cells. Its mechanism may involve UPP via decreasing the expression of Ub and increasing that of 26S， E3， UCHL1， and UCHL3.

ObjectiveTo analyze the effects of Danggui Shaoyaosan （DSS） on the gut microbiota of the Alzheimer's disease （AD） model in SAMP8 mice based on 16S rDNA sequencing. MethodTwenty-four SAMP8 mice aged seven months were randomly divided into low-， medium-， and high-dose DSS groups （14.4， 28.8， 57.6 g·kg^-1·d^-1） and a model group according to a random number table， with six rats in each group. Six SAMR1 mice of the same age were assigned to the normal group. After intragastric administration for eight consecutive weeks， 16S rDNA sequencing was performed to detect the gut microbiota of feces in mice. Morris water maze was employed to assess the directional navigation and space exploration ability of mice. Nissl staining was performed to observe the pathological changes of neurons in the hippocampal CA1 area. Enzyme-linked immunosorbent assay （ELISA） was adopted to measure the protein content of hippocampal amyloid β-protein （Aβ） and hyperphosphorylated Tau （p-Tau）. ResultCompared with the normal group， the model group presented a declining α diversity （P<0.05）， markedly altered β diversity， prolonged escape latency （P<0.05）， reduced number of platform crossings and cumulative duration in the targeted quadrant （P<0.05）， decreased neurons and Nissl bodies in the CA1 hippocampal area， and up-regulated Aβ and p-Tau expression （P<0.05）. However， DSS intervention enhanced the α diversity， and medium- and high-dose DSS， especially the medium-dose DSS， could result in α diversity similar to the control group. Moreover， at the phylum level， the abundance of Firmicutes increased （P<0.05）， while the abundance of Bacteroidetes and Proteobacteria decreased （P<0.05）. At the genus level， the abundance of Lactobacillus and other genera increased （P<0.05）， while the abundance of Bacteroides， Helicobacterium， Rikenella， Parabacteroides， Sutterella， and Mucilaginibacter decreased （P<0.05）. The DSS groups also showed shortened escape latency （P<0.05）， increased number of platform crossings and cumulative duration in the targeted quadrant （P<0.05）， increased Nissl bodies （P<0.05）， and reduced Aβ and p-Tau content （P<0.05）. Pearson correlation analysis showed that the abundance of Mucilaginibacter， Bacteroides， and Sutterella was negatively correlated with the cognitive ability of SAMP8 mice， while the abundance of Lactobacillus and Butyricimonas was positively correlated with the cognitive ability of SAMP8 mice. ConclusionDSS can improve the cognitive ability of SAMP8 mice， and its mechanism may be related to the regulation of gut microbiota diversity and community composition.

Objective:To determine the median effective dose (ED 50) of 0.5% ropivacaine based on femoral nerve cross-sectional area for ultrasound-guided femoral nerve block. Methods:Patients of both sexes, aged 18-64 yr, of American Society of Anesthesiologists physical status I or Ⅱ, with body mass index of 20-30 kg/m 2, scheduled for elective open reduction and internal fixation for patella fracture or removal of patella fracture by internal fixation, were enrolled in this study.Ultrasonic localization of femoral nerve was performed for measurement of the femoral nerve cross-sectional area, and 0.5% ropivacaine was injected based on the area.ED 50 was determined by Dixon′s up-and-down sequential method.The initial dose was 0.22 ml/mm 2, and the difference between the two successive doses was 0.02 ml/mm 2.The effective block was defined as complete loss of pain sensation in the areas of anterior skin of knee joint, skin on the inner side of the calf and dorsal medial skin of the foot and the degree of motor block was in stages 1-3 assessed using Brunnstrom motor function within 30 min after nerve block.Nerve block was considered ineffective if pain occurred in any nerve distribution area mentioned above.The study was terminated if 7 effective and ineffective alternating waves occurred.ED 50 and 95% confidence interval (CI) were calculated using Probit analysis. Results:Twenty-seven patients were enrolled in the study with the femoral nerve cross-sectional area (75±5) mm 2.ED 50 (95%CI) of 0.5% ropivacaine for ultrasound-guided femoral nerve block was 0.106 (0.069-0.125) ml/mm 2. Conclusion:ED 50 of 0.5% ropivacaine based on femoral nerve cross-sectional area for ultrasound-guided femoral nerve block is 0.106 ml/mm 2.

Objective: To explore the application of the King′s theory for the standardized training of new recruited nurses based on Tower platform. Methods: Totally 167 new recruited nurses were randomly divided into the intervention group (n=84) and the control group (n=83). The nurses in the intervention group were taught with the teaching mode of King′s theory based on Tower platform while the control group were taught with routine teaching. Results: After training, the scores of autonomous learning ability, self-motivated belief, task analysis, self-monitoring and regulation, self-evaluation in the intervention group were 124.30±19.34, 52.47±7.01, 23.01±4.03, 34.24±6.17, 14.58±3.83, higher than those in the control group 116.81±15.52, 50.78±6.01, 21.07±3.72, 31.64±5.38, 13.32±3.01, and the differences were significant (t=-5.540-3.134, P<0.05). The theoretical scores in the intervention group (91.37±3.47) were higher than those in the control group (82.68±6.21), and the differences were significant (t=5.172, P<0.05). The scores of the competency of registered nurses in the intervention group (154.75±32.45) were higher than those in the control group (147.82±27.63), and the differences were significant (t=7.68, P<0.05). The total score of nurses in intervention group was 27.79±3.50, which was significantly higher than 20.75±2.54 in the control group, and the difference was statistically significant (t=-8.682, P<0.05). Conclusions The King′s theory for the standardized training of new recruited nurses based on Tower platform helps to promote the quality of teaching. The training method is well accepted and recognized by the new recruited nurses.

Objective To evaluate the effect of propofol on high-mobility group box 1 protein (HMGB1)/Toll-like receptor 4 (TLR4) signaling pathway during hepatic ischemia-reperfusion (I/R) injury in rats.Methods Thirty-six clean-grade healthy male Sprague-Dawley rats,aged 3 months,weighing 250 -300 g,were divided into 3 groups (n=12 each) using a random number table method:sham operation group (group S),hepatic I/R group (group I/R) and propofol group (group P).Hepatic I/R injury was induced by occluding the portal vein and hepatic artery supplying the left and middle lobes of the liver for 1 h followed by 6-h reperfusion in anesthetized rats.Propofol was infused via the tail vein at a rate of 12 mg ·kg-1 · h-1 starting from 20 min before ischemia until 6 h of reperfusion in group P.The rats were sacrificed at 6 h of reperfusion,and the left lobe of the liver was removed for microscopic examination of the pathological changes which were scored and for determination of the expression of HMGB1,TLR4,tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-6) in liver tissues (by Western blot).Results Compared with group S,pathological scores of liver tissues were significantly increased,and the expression of HMGB1,TLR4,TNF-α and IL-6 was up-regulated in I/R and P groups (P＜0.05).Compared with group I/R,pathological scores of liver tissues were significantly decreased,and the expression of HMGB1,TLR4,TNF-α and IL-6 was down-regulated in group P (P＜ 0.05).Conclusion The mechanism by which propofol reduces liver I/R injury is associated with blocking HMGB-1/TLR4 signaling pathway and inhibiting inflammatory responses in rats.
