Objective To explore the role of indole-3-propionic acid(IPA)in the pathogenesis of metabolic associated fatty liver disease(MAFLD)induced by high-fat diet(HFD)in order to reveal the role and related mechanism of adipose tissue metabolism in the process.Methods A mouse model of MAFLD was induced by HFD.Male C57BL/6J mice(6～7 weeks old)were randomly divided into control group(CON),HFD group,and HFD+IPA intervention group(HFD+IPA).The CON group was fed with control diet,and the HFD group and HFD+IPA group were fed with 60％of high-fat diet.The experiment period was 12 weeks,and IPA was administered at 20 mg/(kg·d)for 6 weeks starting from the 7th week.The body weight and food intake of each group were monitored weekly.After the intervention,the body composition of mice was detected by animal body composition analyzer.After the mice were euthanized,the morphological and structural changes in the liver and adipose tissues were observed by HE staining,the indicators relevant to lipid metabolism in the serum,l iver and adipose tissues were detected by automatic blood biochemical analyzer and biochemical kits,and the mRNA expression changes of lipid metabolism and inflammation related genes were detected by qRT-PCR.Results Compared with the CON group,the HFD group had significantly increased body weight and body fat percentage,obvious lipid deposition in the liver,obviously elevated serum alanine aminotransferase,aspartate aminotransferase,liver triglyceride and total cholesterol levels(P＜0.05),and raised mRNA levels of liver fatty acid transporter CD36(P＜0.05),while IPA intervention significantly reversed the above changes(P＜0.05).IPA intervention significantly inhibited the HFD-induced enlargement of visceral and brown fat cells,reduced the content of visceral adipose tissue(VAT)and serum level of free fatty acids(P＜0.05),and increased the mRNA expression levels of VAT lipolysis(HSL,CGI58),browning genes(Cidea,ND5,UCP1,Prdm16)(P＜0.05),as well as those of brown adipose tissue(BAT)lipolysis(HSL,ATGL)and fatty acid beta oxidation(Cpt1a,PPARα)genes(P＜0.05).Meanwhile,the mRNA levels of TNF-α,IL-1β,CXCL1 and CCL2 in VAT and BAT were decreased after IPA intervention(P＜0.05).Conclusion IPA can improve the occurrence of MAFLD induced by HFD,and its mechanism may be closely associated with its regulation of BAT and VAT morphology,and the mRNA expression of metabolic function and inflammation related genes.

Objective To explore the effect of chenodeoxycholic acid(CDCA)on the expression of glucagon-like peptide-1(GLP-1)in the intestine of mice induced by high-fat diet(HFD)through farnesoid X receptor(FXR),and investigate the related mechanism.Methods Forty C57BL/6 mice were divided into control group,HFD group,HFD+CDCA group,HFD+Z-Gug(FXR antagonist)group,and HFD+CDCA+Z-Gug group,with 8 animals in each group.During intervention for 8 weeks,body weight and 24-hour food intake were measured every week.At the 8th week,oral glucose tolerance test(OGTT)and intraperitoneal glucose tolerance test(IPGTT)were conducted.After the mice were sacrificed,the serum levels of GLu,TG,CHO,LDL-C and HDL-C were detected;the expression levels of GLP-1 and FXR in intestinal tissues were detected by immunofluorescence assay;and the mRNA levels of TNF-α,IL-6,IL-1β,Gcg and FXR were detected by RT-qPCR;the serum level of GLP-1 was detected by ELISA,and the proportion of intraepithelial lymphocytes(IELs)subsets and the expression of CD26/DPP4 were detected by flow cytometry.Results Compared with the control group,the HFD group had increased body weight,abnormal serum glucose and lipid metabolism,impaired oral glucose tolerance,and weakened secretion of gastrointestinal hormones(P＜0.05),enhanced FXR expression at mRNA and protein levels,declined Gcg mRNA level and GLP-1 secretion level(P＜0.05),increased mRNA levels of intestinal inflammatory factors TNF-α,IL-6 and IL-1β(P＜0.05),raised proportions of TCRαβ+IELs,TCRαβ+CD8αα+IELs,and TCRαβ+CD8αβ+IELs but reduced proportion of TCRγδ+IELs,and increased total CD26/DPP4 expression in IELs(P＜0.05).Compared with the HFD group,HFD+CDCA treatment resulted in significantly increased body weight,impaired oral glucose tolerance,decreased secretion of gastrointestinal hormones,increased FXR mRNA and protein expression,and decreased Gcg mRNA expression and GLP-1 secretion(P＜0.05);decreased proportions of TCRαβ+IELs,TCRαβ+CD8αα+IELs and TCRααβ+CD8αβ+IELs but increased proportion of TCRγδ+ cells in IELs,and increased expression of total CD26/DPP4 in IELs(P＜0.05),which were significantly improved after Z-Gug intervention(P＜0.05).Conclusion CDCA may inhibit the expression and secretion of GLP-1 in intestinal tissue by activating FXR,and reduce the secretion of GLP-1.At the same time,CDCA may inhibit the expression of related inflammatory factors,regulate the proportions of IELs subsets,up-regulate the expression level of CD26/DPP4,promote the degradation of GLP-1 and aggravate insulin resistance.

Objective:To compare the clinical efficacy of the H-Loop knotless double-row technique and the suture bridge technique in repairing L-shaped rotator cuff tears under arthroscopy.Methods:A retrospective analysis was performed on 58 patients with L-shaped rotator cuff injuries who underwent arthroscopic repair at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, between January 2019 and December 2021. The H-Loop knotless double-row technique was used in 16 cases (8 males and 8 females, mean age 63.69±8.78 years), while the suture bridge technique was used in 42 cases (24 males and 18 females, mean age 61.02±7.02 years). The American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles Shoulder Score (UCLA), Simple Shoulder Test (SST), shoulder range of motion, and muscle strength were evaluated and compared between the two groups one year after surgery.Results:The follow-up period was 12.81±0.98 months for the H-Loop group and 13.29±0.94 months for the suture bridge group. No significant differences were found between the groups in terms of age, sex, dominant hand, preoperative symptom duration, tear shape, tear size, or long head tendon amputation (P>0.05). The operative time was significantly shorter in the H-Loop group 67.50±16.02 minutes compared to the suture bridge group 76.67±13.19 minutes ( t=2.234, P=0.031). Additionally, the number of anchors used was significantly lower in the H-Loop group 2.00±0 compared to the suture bridge group 4.14±0.35 ( t=16.573, P<0.001). The ASES scores increased significantly in both groups: from 57.44±15.91 to 92.00±4.41 in the H-Loop group and from 58.21±16.58 to 87.71±6.19 in the suture bridge group ( F=53.439, P<0.001; F=72.511, P<0.001). Similarly, the UCLA scores improved from 20.63±3.79 to 31.56±3.65 in the H-Loop group and from 20.83±5.78 to 30.36±4.71 in the suture bridge group ( F=57.788, P<0.001; F=50.043, P<0.001). The Constant-Murley scores also showed significant improvement: from 68.50±15.31 to 87.5±8.70 in the H-Loop group and from 66.21±16.51 to 86.33±9.14 in the suture bridge group ( F=6.733, P<0.001; F=30.173, P<0.001). SST scores increased from 6.38±3.76 to 9.06±2.59 in the H-Loop group and from 6.55±3.31 to 9.17±2.45 in the suture bridge group ( F=2.847, P<0.001; F=11.096, P<0.001). The shoulder flexion range of motion increased from 158.75°±21.25° to 178.75°±47.07° in the H-Loop group and from 139.29°±45.12° to 179.76°±3.42° in the suture bridge group ( t=3.814, P=0.002; t=5.877, P<0.001). Shoulder abduction motion increased from 145°±45.46° to 178.75°±3.42° in the H-Loop group and from 135.24°±47.07° to 179.76°±1.54° in the suture bridge group ( t=2.952, P=0.001; t=6.185, P<0.001). Muscle strength improved from 53.36±25.21 N to 73.69±24.09 N in the H-Loop group and from 43.31±24.49 N to 61.8±30.07 N in the suture bridge group ( t=4.916, P<0.001; t=5.623, P<0.001). The ASES score at one year post-surgery was significantly higher in the H-Loop group 92.00±4.41 compared to the suture bridge group 87.71±6.19 ( t=2.529, P=0.014). There were no significant differences in UCLA scores, Constant-Murley scores, SST scores, shoulder motion, or muscle strength between the groups ( P>0.05). Conclusion:The H-Loop technique provides a good early curative effect. Compared to the traditional suture bridge technique, the H-Loop technique offers a higher early postoperative ASES score, shorter operative time, and fewer anchors required.

OBJECTIVE: To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength. METHODS: A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.5 years). Preoperative visual analogue scale (VAS) score was 6.0±1.6. CSA measurements were obtained from standard anteroposterior X-ray films before operation, and patients were divided into two groups based on CSA measurements: CSA>35° group (group A) and CSA≤35° group (group B). Handheld dynamometry was used to measure the muscle strength of various muscle group in the shoulder (including the supraspinatus, infraspinatus, subscapularis, and anterior, middle, and posterior bundles of the deltoid). The muscle strength of the unaffected side was compared to the affected side, and muscle imbalance indices were calculated. Muscle imbalance indices between male and female patients, dominant and non-dominant sides, and groups A and B were compared. Pearson correlation analysis was used to examine the relationship between muscle imbalance indices and CSA as well as VAS scores. RESULTS: Muscle strength in all muscle groups on the affected side was significantly lower than on the unaffected side ( P<0.05). The muscle imbalance indices for the supraspinatus, subscapularis, infraspinatus, and anterior, middle, and posterior bundles of the deltoid were 14.8%±24.4%, 5.9%±9.7%, 7.2% (0, 9.1%), 17.2% (5.9%, 26.9%), 8.3%±21.3%, and 10.2% (2.8%, 15.4%), respectively. The muscle imbalance indices of the anterior bundle of the deltoid, supraspinatus, and infraspinatus were significantly lower in male patients compared to female patients ( P<0.05); however, there was no significant difference in muscle imbalance indices among other muscle groups between male and female patients or between the dominant and non-dominant sides ( P>0.05). There was a positive correlation between the muscle imbalance indices of infraspinatus and VAS score ( P<0.05), and a positive correlation between CSA and the muscle imbalance indices of middle bundle of deltoid ( P<0.05). There was no correlation between the muscle imbalance indices of other muscle groups and VAS score or CSA ( P>0.05). Preoperative CSA ranged from 17.6° to 39.4°, with a mean of 31.1°. There were 9 cases in group A and 33 cases in group B. The muscle imbalance indices of the anterior bundle of the deltoid was significantly lower in group A compared to group B ( P<0.05), while there was no significant difference in muscle imbalance indices among other muscle groups between group A and group B ( P>0.05). CONCLUSION Patients with RCT have a phenomenon of deltoid muscle strength reduction, which is more pronounced in the population with a larger CSA.

OBJECTIVE: To explore the clinical characteristics of hospitalized patients with hematologic diseases complicated with carbapenem-resistant organisms (CRO) infection and analyze the risk factors of 30-day all-cause mortality. METHODS: The clinical data and laboratory test data of 77 hospitalized patients with hematologic diseases complicated with CRO infection in department of hematology of the Third Hospital of Shanxi Medical University from January 2015 to December 2020 were retrospectively analysed, the risk factors of 30-day all-cause mortality after CRO infection were analyzed by multivariate logistic regression. RESULTS: Among the total of 77 patients with hematologic diseases complicated with CRO infection, 29 died and 48 survived within 30 days of infection, with a case fatality rate of 37.66%. A total of 93 strains of CRO were isolated from these patients, of which Acinetobacter baumannii had the highest detection rate (25.81%, 24/93), followed by Pseudomonas aeruginosa (18.28%, 17/93). The lung was the most common site of CRO infection. The detected pathogens were highly resistant to carbapenems, and 64.52% (60/93) of the pathogens were resistant to imipenem with minimum inhibitory concentration (MIC)≥16 μg/ml. The results of the univariate analysis showed that albumin concentration <25 g/L (P =0.048), serum creatinine concentration≥120 μmol/L (P =0.023), age-adjusted Charlson comorbidity index (ACCI) (P =0.037) and primary treatments (supportive treatment, immunosuppressive therapy, chemotherapy, HSCT) (P =0.048) were significantly associated with 30-day all-cause mortality after infection. The results of multivariate logistic regression analysis showed that when CRO infection confirmed, albumin concentration <25 g/L (P =0.014, OR=6.171), serum creatinine concentration≥120 μmol/L (P =0.009, OR=10.867) were independent risk factors for 30-day mortality of patients with hematologic diseases complicated with CRO infection. CONCLUSION The mortality rate of CRO-infected patients with hematologic diseases is high. The detected pathogenic bacteria are highly resistant to imipenem. The albumin concentration <25 g/L and the serum creatinine concentration≥ 120 μmol/L at diagnosis of CRO infection were independent risk factors for 30-day mortality of the patients with hematologic diseases.

Objective: To investigate the clinicopathological features and differential diagnosis of NTRK3 gene rearrangement thyroid papillary carcinoma (PTC). Methods: The PTC cases without BRAF V600E mutation were collected at Fujian Provincial Hospital South Branch from January 2015 to January 2020. The cases of NTRK3 gene rearrangement PTC were examined using immunohistochemistry and fluorescence in situ hybridization (FISH). The clinical data, histopathological characteristics, immunohistochemical features and molecular pathological changes were retrospectively analyzed. Data from the TCGA PTC dataset and the literature were also studied. Results: A total of 3 PTC cases harboring NTRK3 gene rearrangement were confirmed. All the patients were female, aged from 26,49,34 years. Histologically, two of them demonstrated a multinodular growth pattern. Only one case showed prominent follicular growth pattern; the other two tumors showed a mixture of follicular, papillary and solid growth patterns. All tumors showed a typical PTC nuclear manifestation, with some nuclear pleomorphism, vacuolated foci and oncocytic features. The characteristic formation of glomeruloid follicular foci was present in two cases which also showed psammoma bodies, and tumoral capsular or angiolymphatic invasion. The background thyroid parenchyma showed chronic lymphocytic thyroiditis. Mitotic rates were low, and no cases had any tumor necrosis. The pan-TRK and TTF1 testing was both positive in 3 cases, while S-100 and mammaglobin were both negative in them. FISH studies confirmed the NTRK3 gene rearrangement in all 3 cases. Studies on the TCGA datasets and literature revealed similar findings. Conclusions: NTRK3 gene rearrangement PTC is rare. It may be easily misdiagnosed due to the lack of histological and clinicopathological characteristics. Molecular studies such as pan-TRK immunostaining, FISH and even next-generation sequencing are needed to confirm the diagnosis. Immunohistochemistry of pan-TRK performed in the PTC cases without BRAF V600E mutation can be used as a good rapid-screening tool. With the emergence of pan-cancer tyrosine receptor kinase inhibitors, proper diagnosis of these tumors can help determine appropriate treatments and improve their outcomes.

BACKGROUND: Recently, T-helper 17 (Th17) cells have been proved to play an important role in promoting cervical cancer. But, till now, few study has been carried out to understand the involvement of these cells in efficacy of anti-tumor treatments. This study aimed to investigate the alterations in the percentage of circulating Th17 cells and related cytokines in locally advanced cervical cancer (LACC) patients before and after concurrent chemoradiotherapy (cCRT) and to analyze the correlations between the alterations in Th17 cells and treatment efficacy. METHODS: A prospective study with 49 LACC (International federation of gynecology and obstetrics [FIGO] stage IIB-IIIB) patients and 23 controls was conducted. Patients received the same cCRT schedule and were followed up for 3 years. Circulating Th17 cells (CD3+CD8- interleukin [IL]-17+ T cells) and related cytokines IL-17, transforming growth factor-β (TGF-β), IL-10, IL-23, IL-6, and IL-22 were detected before and after cCRT. Correlations between alterations of circulating Th17 cells and treatment efficacy were analyzed. Kaplan-Meier analysis was used for overall survival (OS) and progression-free survival (PFS). RESULTS: We found that 40 patients finished the entire cCRT schedule and met the endpoint of this study. The percentage of circulating Th17 cells in the LACC patients was higher than that in the controls, and it significantly decreased after cCRT (P < 0.05). After cCRT, patients were divided into two groups based on the average of the Th17 cells declined. The subgroup of patients with a prominent decrease in circulating Th17 cells after cCRT had a higher treatment efficacy and longer PFS and OS times. Compared with the control patients, LACC patients had higher IL-6, IL-10, IL-22, TGF-β levels and a lower IL-23 level (P < 0.05). After cCRT, IL-6, IL-10, IL-17, IL-23 level significantly increased and TGF-β level significantly decreased compared with the levels before cCRT (P < 0.05). CONCLUSION Circulating Th17 cells in the LACC patients (FIGO stage IIB-IIIB) were higher than those in the controls, but they generally decreased after cCRT. A more pronounced decrease in circulating Th17 cells after cCRT was correlated with better therapeutic effect and longer PFS and OS times.
