Objective To evaluate the efficacy and safety of CT-guided 125I seeds implantation for the treatment of abdominal wall incision metastasis of gastrointestinal malignancies.Methods The clinical data of 17 patients with abdominal wall incision metastasis of gastrointestinal malignancies(17 lesions in total),who received CT guided 125I seeds implantation at the Third Affiliated Hospital of Soochow University of China between January 2011 and December 2021,were collected.The treatment planning system was used to make preoperative planning for CT-guided 125I seeds implantation.Follow-up visit was performed once every 3 months to assess the local control rate,treatment-related adverse effects,and degree of pain relief.Results Successful CT-guided 125I seeds implantation was accomplished for the 17 lesions of gastrointestinal malignant tumor incision metastasis.A total of 372 125I seeds were implanted with an average of 21.9 seeds per lesion.The average prescription dose was 100 Gy per lesion.The average survival time was 9.8 months.CT scan performed at 3 months after first-time implantation showed that among the 17 lesions complete remission was obtained in 3,partial remission in 6,stable disease in 7 and progression in one,with a local control rate of 94.1％.The postoperative 6-month and 12-month local objective remission rates were 63.6％and 33.3％respectively,disease control rates were 100％and 50％respectively.Before treatment 8 patients had local pain,and 3 months after treatment pain relief was observed in 6 patients,and in 2 patients the NRS pain score was decreased by ≥ 2 points.No serious postoperative complications occurred.Conclusion For the treatment of abdominal wall incision metastasis of gastrointestinal metastasis,CT-guided 125I seeds implantation is clinically safe and effective.(J Intervent Radiol,2024,33:655-658)

Objective To identify the relationship between nephritis activity, autophagy and inflammation in patients with SLE. Methods Western blot analysis was used to detect the expression of microtubule-associated protein 1 light chain 3 (LC3) and P62 in peripheral blood mononuclear cells (PBMCs) of SLE patients with lupus nephritis and non-lupus nephritis patients. Tumor necrosis factor α (TNF-α) and interferon γ (IFN-γ) in the serum of SLE patients were determined by ELISA. The correlation between LC3II/LC3I ratio and SLE disease activity score (SLEDAI), urinary protein, TNF-α and IFN-γ levels was analyzed by Pearson method. Results The expression of LC3 was increased and P62 was decreased in SLE patients. TNF-α and IFN-γ were increased in the serum of SLE patients. LC3II/LC3I ratio was positively correlated with SLEDAI (r=0.4560), 24 hour urine protein (r=0.3753), IFN-γ (r=0.5685), but had no correlation with TNF-α (r=0.04 683). Conclusion Autophagy is found in PBMCs of SLE, and the autophagy is correlated with renal damage and inflammation in patients with lupus nephritis.

Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF's anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.

ObjectiveTo observe the effect of surface sensation training on walking function of patients after anterior cruciate ligament reconstruction (ACLR). MethodsFrom January to November, 2021, 56 ACLR inpatients in Beijing Rehabilitation Hospital were randomly divided into control group (n = 28) and experimental group (n = 28). The control group received routine rehabilitation training of 45 minutes a time, while the experimental group received routine rehabilitation training of 30 minutes and surface sensation training of 15 minutes a time, for eight weeks. Their toe-out angle and affected side impulse percentage of plantar seven zones were measured before and after intervention. ResultsThe toe-out angle of both the healthy and the affected sides decreased in both groups after intervention (t > 4.615, P < 0.001), and it was less in the affected side in the experimental group (t = 2.263, P < 0.05). The impulse percentage in heel medial and heel lateral areas increased in both groups after intervention (t > 4.221, P < 0.001), and it was more in the experimental group (t > 3.651, P < 0.01); while the impulse percentage in middle foot, foot intermediate and foot lateral areas decreased in both groups (t > 3.174, P < 0.01), and it was less in foot intermediate and foot lateral areas in the experimental group (t > 2.366, P < 0.05); the impulse percentage decreased in foot medial and toe areas in the experimental group (t > 3.508, P < 0.01), but there was no significant difference between two groups (t < 1.608, P > 0.05). ConclusionSurface sensation training can further improve the foot deflection and distribution of impulse of affected side in patients after ACLR during walking, to normalize the load patterns.

MethodRaw264.7 cells were cultured in vitro by serum pharmacological method， and the hypoxia model of RAW264.7 cells was established by stimulating RAW264.7 cells with cobalt chloride （CoCl₂）. The cells were randomly divided into blank group， CoCl₂ hypoxia model group （200 mmol·L^-1）， Biejiajian Wan low-dose group （200 mmol·L^-1+0.55 g·kg^-1 Fuzheng Quyu capsules）， medium-dose group （200 mmol·L^-1+1.1 g·kg^-1 Biejiajian Wan）， and high-dose group （200 mmol·L^-1+2.2 g·kg^-1 Biejiajian Wan） and Fuzheng Quyu capsule group （200 mmol·L^-1+0.56 g·kg^-1 Biejiajian Wan）. Cell proliferation was detected by cell counting kit-8 （CCK-8）， and the gene expression of hypoxia inducible factor-1α （HIF-1α）， interleukin-1β （IL-1β） and interleukin-6 （IL-6） in macrophages was detected by real time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The expression of macrophage polarization-related protein and HIF-1α/nuclear factor-kappa B （NF-κB） signaling pathway-related protein was tested by Western blot， and the distribution and expression of NF-κB signaling pathway-related protein and HIF-1α were determined by cell immunofluorescence. ResultCompared with the conditions in the blank group， the proliferation of RAW264.7 cells was inhibited after CoCl₂ stimulation for 24 hours （P<0.05）， the mRNA expression of HIF-1α， IL-1β and IL-6 in the model group were increased （P<0.05）， the protein expression of HIF-1α and M1 macrophage phenotypic proteins IL-6 and tumor necrosis factor-α （TNF-α） was boosted while that of M2 macrophage phenotypic protein interleukin-10 （IL-10） was reduced （P<0.05）， the protein expression of NF-κB p65， phosphorylation （p）-NF-κB p65， phosphorylated NF-κB inhibits protein kinase α/β （p-IKKα/β） and phosphorylated NF-κB inhibits protein α (p-IκBα） was elevated （P<0.05）， the nuclear expression of HIF-1α and NF-κB p65 was promoted. Compared with the conditions in the model group， after 24 hours of treatment with corresponding drug-containing serum， each treatment group promoted the proliferation of RAW264.7 cells （P<0.05）， the mRNA expression levels of HIF-1α， IL-1β and IL-6 in macrophages were reduced （P<0.05）， the protein expression of HIF-1α， IL-6 and TNF-α was decreased， while that of CD163 and IL-10 was increased （P<0.05）， the protein expression of NF-κB p65， p-NF-κB p65， p-IKKα/β and p-IκBα was lowered （P<0.05）， the nuclear expression of HIF-1α and NF-κB p65 was inhibited. ConclusionBiejiajian Wan could modulate the polarization of macrophages， attenuate the injury of macrophage-associated inflammatory response under hypoxia， and thus delay the progression of liver fibrosis， which might be related to its regulation of HIF-1α/NF-κB signaling pathway.

Objective To investigate the relationship between BMI and blood lipids, blood glucose and blood uric acid. Methods A total of 3 860 employees from a university who underwent physical examination in 2018 were selected and divided into obesity group, fat group, normal group and lean group according to their body mass index. The levels of blood lipids, fasting blood glucose and blood uric acid among different groups were analyzed and compared. Results There were a total of 1,889 people in the obesity group and fat group, accounting for 48.94% of the total. The weight difference among the different groups was statistically significant (P＜0.05), while there was no statistical significance in age difference among different groups. The height in the obese group and fat group was significantly different compared with the normal group. There were significant differences in the levels of triglyceride (TG), high-density lipoprotein (HDL-C) and blood uric acid (UA) in the different groups (P<0.05). The fasting blood glucose level (GLU) in both the obesity group and fat group was significantly different compared with the normal group (P<0.05). With the increase in body weight index, the proportion of high blood fat, fatty liver, hyperglycemia and high blood uric acid all increased significantly as compared with the normal group or the lean group, and the differences were statistically significant (P<0.05). The proportion of fatty liver and hyperuricemia in the male was higher than that in the female. Conclusion The risk of high blood fat, fatty liver, hyperglycemia and hyperuricemia in college faculty and staff was significantly increased with the increase of BMI. It is suggested that the college employees should have a balanced diet, increase exercise, and control BMI within a reasonable range.
