OBJECTIVE:
To elucidate how spinal manipulative therapy (SMT) exerts its analgesic effects through regulating brain function in lumbar disc herniation (LDH) patients by utilizing resting-state functional magnetic resonance imaging (rs-fMRI).
METHODS:
From September 2021 to September 2023, we enrolled LDH patients (LDH group, n=31) and age- and sex-matched healthy controls (HCs, n=28). LDH group underwent rs-fMRI at 2 distinct time points (TPs): prior to the initiation of SMT (TP1) and subsequent to the completion of the SMT sessions (TP2). SMT was administered once every other day for 30 min per session, totally 14 treatment sessions over a span of 4 weeks. HCs did not receive SMT treatment and underwent only one fMRI scan. Additionally, participants in LDH group completed clinical questionnaires on pain using the Visual Analog Scale (VAS) and the Japanese Orthopedic Association (JOA) score, whereas HCs did not undergo clinical scale assessments. The effects on the brain were jointly characterized using the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo). Correlation analyses were conducted between specific brain regions and clinical scales.
RESULTS:
Following SMT treatment, pain symptoms in LDH patients were notably alleviated and accompanied by evident activation of effects in the brain. In comparison to TP1, TP2 exhibited the most significant increase in ALFF values for Temporal_Sup_R and the most notable decrease in ALFF values for Paracentral_Lobule_L (voxelwise P<0.005; clusters >30; FDR correction). Additionally, the most substantial enhancement in ReHo values was observed for the Cuneus_R, while the most prominent reduction was noted for the Olfactory_R (voxelwise P<0.005; clusters >30; FDR correction). Moreover, a comparative analysis revealed that, in contrast to HCs, LDH patients at TP1 exhibited the most significant increase in ALFF values for Temporal_Pole_Sup_L and the most notable decrease in ALFF values for Frontal_Mid_L (voxelwise P<0.005; clusters >30; FDR correction). Furthermore, the most significant enhancement in ReHo values was observed for Postcentral_L, while the most prominent reduction was identified for ParaHippocampal_L (voxelwise P<0.005; clusters >30; FDR correction). Notably, correlation analysis with clinical scales revealed a robust positive correlation between the Cuneus_R score and the rate of change in the VAS score (r=0.9333, P<0.0001).
CONCLUSIONS
Long-term chronic lower back pain in patients with LDH manifests significant activation of the "AUN-DMN-S1-SAN" neural circuitry. The visual network, represented by the Cuneus_R, is highly likely to be a key brain network in which the analgesic efficacy of SMT becomes effective in treating LDH patients.

ObjectiveTo investigate the effect of rutin on the browning of 3T3-L1 preadipocytes and the mechanism. MethodCell counting kit-8 (CCK-8) assay was used to detect the effect of different concentration of rutin (3.125, 6.25, 12.5, 25, 50, 100, 200 μmol·L-1) on 3T3-L1 cell activity, and Western blot to examine the effect of rutin (12.5, 25, 50 μmol·L-1) on the expression of thermogenesis-associated proteins uncoupling protein 1 (UCP1), PR domain containing 16 (PRDM16) and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) in adipocytes. After the optimal concentration of rutin was determined, the effect of rutin on lipid droplet formation in adipocytes was observed based on oil red O staining, and the expression of nuclear respiratory factor 1 (NRF1), nuclear respiratory factor 2 (NRF2) and mitochondrial transcription factor A (TFAM), which were the landmark proteins of mitochondrial biosynthesis, was detected by Western blot. ResultCompared with the blank group, 200 μmol·L-1 rutin inhibited 3T3-L1 cell activity (P<0.01). Compared with the blank group, at the concentration of 12.5, 25, 50 μmol·L-1 rutin significantly promoted the expression of thermogenesis-associated proteins (UCP1, PRDM16, and PGC-1α) (P<0.01), which was determined as the optimal concentration. Compared with the blank group, 50 μmol·L-1 rutin significantly increased the immunofluorescence intensity of mitochondrial UCP1 protein in 3T3-L1 cells (P<0.01) and the expression of the markers of mitochondrial biosynthesis (NRF1, NRF2, and TFAM) (P<0.01). In addition, 50 μmol·L-1 rutin significantly inhibited lipid droplet formation of 3T3-L1 adipocytes (P<0.01). ConclusionRutin inhibited lipid droplet deposition in 3T3-L1 adipocytes and increased the expression of thermogenesis-related proteins (UCP1, PRDM16, and PGC-1α) and markers of mitochondrial biosynthesis (NRF1, NRF2, and TFAM), thereby inducing the browning of 3T3-L1 adipocytes. This lays a basis for the development of drugs that safely regulate the browning of white cells.

Objective:To investigate the short-term efficacy and safety of Donafenib as postoperative adjuvant therapy for patients with high risk of recurrence after radical resection of hepatocellular carcinoma (HCC).Methods:The propensity score matching (PSM) and retrospective cohort study was conducted. The clinicopathological data of 157 HCC patients with high risk of recurrence after radical resection who were admitted to 6 medical centers, including The First Affiliated Hospital of Nanjing Medical University et al, from June 2021 to February 2023 were collected. There were 128 males and 29 females, aged (59±10)years. Of 157 patients, 101 cases undergoing Donafenib as postoperative adjuvant therapy were divided into the the Donafenib group, and 56 cases under-going no systemic postoperative adjuvant therapy were divided into the control group. Observation indicators: (1) PSM and comparison of general data of patients between the two groups after matching; (2) postoperative treatment; (3) follow-up and survival of patients; (4) analysis of risk factors affecting recurrence-free survival of patients. PSM was done based on the principle of optimal perfect matching, with the clamp value of 0.5, and the Donafenib group and the control group were matched at a ratio of 1.25∶1. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and/or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Kruskal-Wallis H test. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and the Log-Rank test was used for survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) PSM and comparison of general data of patients between the two groups after matching. Of 157 patients, 126 cases were successfully matched, including 70 cases in the Donafenib group and 56 cases in the control group, respectively. The elimination of tumor number confounding bias ensured comparability between the two groups after PSM. (2) Postoperative treatment. After PSM, of 70 patients in the Donafenib group, there were 23 cases receiving Donafenib monotherapy, 26 cases combined with transcatheter arterial chemoembolization (TACE), 14 cases combined with immunotherapy, and 7 cases combined with TACE+immunotherapy. Of 56 patients in the control group, there were 37 cases receiving postoperative follow-up alone and 19 cases combined with TACE. (3) Follow-up and survival of patients. All 157 patients were followed up, and the follow-up time of the 101 patients in Donafenib group and the 56 patients in control group were 10.1(range, 6.3-14.6)months and 22.2(range, 15.1-25.5)months, respectively. During the follow-up period, 70 patients in the Donafenib group experienced treatment-related adverse reactions, inclu-ding 8 cases of grade 3 adverse reactions, 23 cases of grade 2 and 39 cases of grade 1 adverse reactions, respectively. After PSM, the postoperative 12-, 18-month recurrence-free survival rates were 83.7%, 83.7% in the 70 patients of Donafenib group and 67.8%, 58.9% in the 56 patients of control group, respectively, showing a significant difference in the postoperative recurrence-free survival time between the two groups ( hazard ratio=0.395, 95% confidence interval as 0.176-0.888, P<0.05). (4) Analysis of risk factors affecting recurrence free survival of patients. Results of multivariate ana-lysis showed that microvascular invasion, vascular thrombus, clinical stage as ⅢA were independent risk factors affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=2.181, 2.612, 2.612, 95% confidence interval as 1.028-4.629, 1.128-6.047, 1.128-6.047, P<0.05), Donafenib as postoperative adjuvant therapy was an independent protective factor affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=0.457, 95% confidence interval as 0.227-0.920, P<0.05). Results of further analysis showed that after PSM, there were significant differences in the postoperative recurrence-free survival time in patients with different clinical factors, including male, age ≥60 years, tumor diameter >5 cm, positive microvascular invasion, positive hepatitis B virus infection, alpha fetoprotein <200 μg/L, between the Donafenib group and the control group ( hazard ratio=0.283, 0.202, 0.174, 0.345, 0.273, 0.180, 95% confidence interval as 0.114-0.707, 0.044-0.937, 0.038-0.794, 0.128-0.929, 0.091-0.819, 0.052-0.620, P<0.05). Conclusion:Donafenib as postoperative adjuvant therapy can effectively reduce the short-term recurrence rate in patients with high risk of recurrence after radical resection of HCC, with good safety and tolerance.

The incidence of diabetes has been on the rise as the result of lifestyle changes, especially the high-fat diet and reduced exercise. Thus, it has become a global public health problem and it is an urgent task to explore effective therapy. There has been an explosion of research on the relationship of transforming growth factor-β (TGF-β) signaling pathways with diabetes complications and tumors, but the role of the pathways in the occurrence and progression of diabetes remains unclear. TGF-β signaling pathways can be activated by many factors, directly or indirectly leading to the apoptosis of islet β cells and insulin resistance (IR), and thus they are expected to become new targets for the treatment of diabetes. TGF-β-related signaling pathways involve AMP-activated proteinkinase (AMPK), protooncogene (c-Myc), Ski-relatednovel protein N (SnoN), Smad ubiquitination regulatory factor 1 (Smurf1), miR-335-5p, and other signaling molecules. They participate in the occurrence and development of IR, apoptosis of islet β cells, insulin secretion disorder, fibrosis of adipocytes, and metabolic disorder of adipocytes, and inhibit the browning of white adipose tissue, playing an important part in the pathological process of human diabetes. According to traditional Chinese medicine (TCM), the pathogenesis of diabetes is the deficiency of Qi and Yin, and the late stage is characterized by the syndrome of Qi deficiency, and Yang deficiency and blood stasis, which should be treated according to the principle of replenishing Qi and nourishing Yin, warming Yang and activating blood. It has been found that the efficacy of some Chinese medicinals and compound prescriptions on diabetes is closely related to the TGF-β signaling pathways. This paper reviews TGF-β-associated signaling pathways, elucidating the roles of them in pathogenesis of diabetes, and analyzes the relationship of TGF-β-associated signaling pathways with the effect of compound Chinese medicine prescriptions against diabetes. This study is expected to lay a theoretical basis for the research on the treatment diabetes.

Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ2 test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.

To provide references for the diagnosis and treatment of congenital granular cell tumor (CGCT), by comprehensive analysis of the clinical data, histopathological and immunohistochemical results. Patients with CGCT were involede, from March 2015 to November 2020, at the Department of Oral and Maxillofacial Surgery of the First Affiliated Hospital of Zhengzhou University. A total of 6 children, aged 3-16 days, 1 male and 5 female, 5 maxillary and 1 mandibular, with maximum tumor diameter of 6-70 mm, were included. The lesions of CGCT were single and connected to the alveolar ridge by a pedicle. The surface of the tumor was covered with a vascular network, and two cases had ulcers on the surface of the tumor. All 6 cases had the tumor removed surgically and there was no recurrence or metastasis in the follow-up visit. Although CGCT is rare, it is a benign tumor and generally does not recur or metastasize after surgery, and has a good prognosis. The prenatal imaging, clinical manifestations after delivery, pathological characteristics and immunohistochemical analyses may provide reference for early diagnosis and treatment of CGCT.

ObjectiveTo investigate the effect and mechanism of Mori Folium extract on the glucose and lipid metabolism disorders in the liver of rats with type 2 diabetes mellitus (T2DM) through the phosphatidylinositol 3-kinase/protein kinase B/peroxisome proliferation-activated receptor α/carnitine palmitoyl transferase-1 (PI3K/Akt/PPARα/CPT-1) signaling pathway. MethodThe T2DM model was induced by the high-fat diet combined with the intraperitoneal injection of streptozotocin (STZ). The model rats were randomly divided into a model group, a metformin (0.2 g·kg-1) group, and a Mori Folium water extract (4.0 g·kg-1) group according to blood glucose and body weight. In the 8-week administration, fasting blood glucose was measured at the same time every week. The histomorphological and fat changes in the rat liver were observed by hematoxylin-eosin (HE) staining and oil red O staining. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in the serum were measured by biochemical methods. Western blot (WB) was used to quantitatively detect the protein expression of p-PI3K,PI3K,p-Akt,Akt,PPARα,and CPT-1 in the rat liver. ResultAfter 8-week administration, the blood glucose of rats was higher in the model group than that in the control group (P<0.01), and lower in the Mori Folium water extract group than that in the model group (P<0.01). The results of HE staining showed that the liver tissue structure of the control group was complete, and the hepatocytes were arranged radially around the central vein, while the hepatocyte injury in the model group was obvious. Compared with the model group, the Mori Folium water extract group showed improved vacuolar degeneration and no lesions such as small bile duct hyperplasia. Oil red O staining showed that there was no obvious steatosis and necrosis in the hepatocytes of rats in the control group, and no lipid droplets in the hepatocytes were observed, while the model group showed increased lipid droplets. Mori Folium significantly reduced the lipid droplets in the liver. Biochemical analysis showed that the levels of TC, TG, LDL-C, AST, and ALT in the model group were significantly higher than those in control group (P<0.01). The levels of TC, TG, LDL-C, AST, and ALT in the Mori Folium water extract group were significantly lower than those in the model group (P<0.05,P<0.01). WB showed that the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 in the model group were lower than those in the control group (P<0.01). Mori Folium water extract could increase the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 (P<0.05 or P<0.01). ConclusionThe hypoglycemic mechanism of Mori Folium water extract may be related to the regulation of the PI3K/Akt/PPARα/CPT-1 signaling pathway.

ObjectiveTo investigate the medicinal effect of total flavonoids of mulberry leaves on regulating liver lipid metabolism disorder in diabetes mellitus type 2 (T2DM) rats, and the mechanism based on liver peroxidase proliferators activate receptors-α (PPAR-α) and carnitine palmityl transferase-1 (CPT-1) proteins. MethodTotal flavonoids of mulberry leaves were extracted and purified by ethanol extraction + macroporous resin purification and then identified. T2DM rat model was induced by high fat diet (HFD) + streptozocin(STZ)method. Rats with blood glucose ≥ 11.1 mmol·L-1 were divided into three administration groups with the high dose (300 mg·kg-1), medium dose (150 mg·kg-1), and low dose (75 mg·kg-1) of total flavonoids of mulberry leaves for 8 weeks, respectively, to observe the weight and blood glucose of the rats. The pathological changes of rat livers were observed by hematoxylin-eosin (HE) staining. Biochemical method was used to detect the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C) of blood lipid metabolism in rats. The messenger ribonucleic acid (mRNA) and protein expressions of PPAR-α and CPT-1 were determined by real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultAfter 8 weeks of intervention of total flavonoids of mulberry leaves, compared with the control group, the food intake, liver index, and fasting blood glucose of rats in the model group increased significantly (P<0.01). Compared with the model group, the food intake, fasting blood glucose, and liver index of rats in the administration groups decreased significantly (P<0.01). The results of HE staining showed that the liver tissue structure of rats in the control group was complete and there was no obvious abnormality. The model group showed vacuolar degeneration and inflammatory infiltration of hepatocytes of rats. There was no obvious abnormality in the liver structure of rats in the administration groups. The results of blood lipid showed that compared with the control group, the levels of TC, TG, and LDL-C increased significantly (P<0.01), but the level of HDL-C decreased significantly (P<0.01) in the model group. Compared with the model group, the levels of TC, TG, and LDL-C decreased significantly (P<0.05, P<0.01), whereas the level of HDL-C increased significantly (P<0.01) in the administration groups. The results of Real-time PCR showed that compared with the control group, the mRNA expression of PPAR-α and CPT-1 of rats in the model group decreased significantly (P<0.01). Compared with the model group, the mRNA expressions of PPAR-α and CPT-1 of rats in the high-dose group increased significantly (P<0.01). The results of Western blot showed that compared with the control group, the protein expressions of PPAR-α and CPT-1 of rats in the model group decreased significantly (P<0.01). Compared with the model group, the protein expressions of PPAR-α and CPT-1 of rats in the high-dose group increased significantly (P<0.05, P<0.01). ConclusionTotal flavonoids of mulberry leaves can effectively reduce blood glucose and improve liver lipid metabolism disorder in T2DM rats. The total flavonoids of mulberry leaves could regulate lipid metabolism and play a hypoglycemic role by activating and regulating PPAR-α and CPT-1 proteins and promoting oxidative decomposition of fatty acids.
