Objective:To study the application of conicity index (CI),body mass index (BMI),waist-to-hip ratio (WHR) and body fat ratio (BFR) in abdominal obesity in maintenance hemodialysis (MHD) patients. Methods The patients who received dialysis treatment in the hemodialysis center of the Third Affiliated Hospital of Chongqing Medical University from September to December 2023 were selected by fixed-point cluster sampling,and the age,dialysis age,height,weight,biochemical examination indexes and other information of the study subjects were collected,and the body composition analysis was performed using InBody S10 and the visceral fat area was used as the basis for the determination of abdominal obesity. The applications of body mass index,body fat ratio,waist-to-hip ratio and conicity index in predicting abdominal obesity in MHD patients were compared. Results A total of 151 patients were enrolled,including 65 patients with abdominal obesity MHD and 86 patients with non-abdominal obesity MHD. The results showed that there were significant differences in gender,weight,BMI,visceral fat area,body fat ratio,waist-to-hip ratio,conicity index and the prevalence of diabetes between patients with abdominal obesity and non-abdominal obesity (all P<0.05). The consistency test results showed that the consistency between using BMI,body fat percentage,and waist hip ratio to determine abdominal obesity with visceral fat area method was weak,with the conicity index Kappa coefficient having the largest value (P<0.05).The analysis of receiver operating characteristic (ROC) curve showed that the area under the ROC curve of conicity index was the highest,0.765,indicating the highest diagnostic efficacy (P<0.05) in MHD patients. Conclusion Conicity index,body mass index,waist-to-hip ratio and body fat ratio can be used in the diagnosis of abdominal obesity in MHD patients,among which the conicity index is more effective.

Histone deacetylases(HDACs)can deacetylate histones,leading to tighter DNA binding,and thereby playing a role in inhibiting gene transcription.On the contrary,histone deacetylase inhibitors(HDACis)can promote chromatin relaxation,enabling various transcription factors to bind specifically to DNA and activate transcription genes.Dental stem cells(DSCs)are human adult stem cells.These cells have the characteristics of less damage and low immune rejection during sampling,and are especially important seed cells in the process of osteogenesis,odontogenesis and other differentiation.A large number of experimental studies have shown that HDACs and HDACis together play important roles in cell division and differentiation,signal transduction,regulation of cellular inflammation and other life processes.This review summarizes the research progress of HDACs and HDACis in regulating osteogenic and odontogenic differentiation of DSCs,aiming to provide insights into the study of the interaction between HDACs and HDACis,and potentially guide clinical application of DSCs in the treatment of tooth and bone injury.

BACKGROUND: Clinical outcomes are poor if patients with acute heart failure (AHF) are discharged with residual congestion in the presence of renal dysfunction. However, there is no single indication to reflect the combined effects of the two related pathophysiological processes. We, therefore, proposed an indicator, congestion and renal index (CRI), and examined the associations between the CRI and one-year outcomes and the incremental prognostic value of CRI compared with the established scoring systems in a multicenter prospective cohort of AHF. METHODS: We enrolled AHF patients and calculated the ratio of thoracic fluid content index divided by estimated glomerular filtration rate before discharge, as CRI. Then we examined the associations between CRI and one-year outcomes. RESULTS: A total of 944 patients were included in the analysis (mean age 63.3 ± 13.8 years, 39.3% women). Compared with patients with CRI ≤ 0.59 mL/min per kΩ, those with CRI > 0.59 mL/min per kΩ had higher risks of cardiovascular death or HF hospitalization (HR = 1.56 [1.13-2.15]) and all-cause death or all-cause hospitalization (HR = 1.33 [1.01-1.74]). CRI had an incremental prognostic value compared with the established scoring system. CONCLUSIONS In patients with AHF, CRI is independently associated with the risk of death or hospitalization within one year, and improves the risk stratification of the established risk models.

italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

OBJECTIVE: Melittin, a cell-penetrating peptide, improves the efficiency of many non-viral gene delivery vectors, yet its application in viral vectors has not been well studied. The non-pathogenic recombinant adeno-associated virus (rAAV) vector is an ideal in vivo gene delivery vector. However, its full potential will only be achieved after improvement of its transduction efficiency. To improve the transduction efficiency of rAAV2 vectors, we attempted to develop a melittin-based rAAV2 vector delivery strategy. METHODS: The melittin peptide was inserted into the rAAV2 capsid either in the loop VIII of all viral proteins (VPs) or at the N terminus of VP2. Various rAAV2-gfp or -fluc vectors were subjected to quantitative real-time polymerase chain reaction and Western blot assays to determine their titers and integrity of capsid proteins, respectively. Alternatively, the vectors based on wild-type capsid were pre-incubated with melittin, followed by transduction of cultured cells or tail vein administration of the mixture to C57BL/6 and BALB/c nude mice. In vivo bioluminescence imaging was performed to evaluate the transgene expression. RESULTS: rAAV2 vectors with melittin peptide inserted in the loop VIII of VPs had low transduction efficiency, probably due to dramatically reduced ability to bind to the target cells. Fusing the melittin peptide at the N-terminus of VP2 produced vectors without the VP2 subunit. Interestingly, among the commonly used rAAV vectors, pre-incubation of rAAV2 and rAAV6 vectors with melittin significantly enhanced their transduction efficiency in HEK293 and Huh7 cells in vitro. Melittin also had the ability to increase the rAAV2-mediated transgene expression in mouse liver in vivo. Mechanistically, melittin did not change the vector-receptor interaction. Moreover, cell counting kit-8 assays of cultured cells and serum transaminase levels indicated melittin had little cytotoxicity. CONCLUSION Pre-incubation with melittin, but not insertion of melittin into the rAAV2 capsid, significantly enhanced rAAV2-mediated transgene expression. Although further in vivo evaluations are required, this research not only expands the pharmacological potential of melittin, but also provides a new strategy to improve gene therapy mediated by rAAV vectors.

OBJECTIVE: To compare the therapeutic effect between Hunyuan moxibustion and oral western medication on diarrhea-predominant irritable bowel syndrome（IBS-D）of spleen and kidney yang deficiency. METHODS: Sixty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a Hunyuan moxibustion group and a western medication group, 30 cases each group. The Hunyuan moxibustion group was treated with Hunyuan moxibustion at Guanyuan（CV 4），40 min each time, once a day; in the western medication group，loperamide hydrochloride capsules (2 mg each time, 3 times a day) and bacillus licheniformis live capsules (0.5 g each time, 3 times a day) were given orally.Both groups were treated for 20 days. The scores of irritable bowel syndrome（IBS）symptom severity scale（IBS-SSS）, IBS quality of life scale (IBS-QOL) and TCM symptom grading quantitative were observed before and after treatment, and the clinical efficacy and safety were evaluated in the two groups. RESULTS: After treatment，each item scores and total scores of IBS-SSS in the two groups were lower than those before treatment（P<0.05）, and the total scores of IBS-QOL were higher than those before treatment (P<0.05)；each item score and total score of IBS-SSS in the Hunyuan moxibustion group were lower than those in the western medication group (P<0.05), and the total score of IBS-QOL in the Hunyuan moxibustion group was higher than that in the western medication group (P<0.05).After treatment, each item score and total score of TCM symptom grading quantitative in the Hunyuan moxibustion group were lower than those before treatment (P<0.05), the abdominal pain, diarrhea, lack of appetite scores and total score in the western medication group were lower than those before treatment (P<0.05)；and the abdominal pain, soreness and weakness of waist and knees, fear to cold and cold limbs scores and total score in the Hunyuan moxibustion group were lower than those in the western medication group (P<0.05).The total effective rate was 90.0%（27/30）in the Hunyuan moxibustion group, which was higher than 73.3%（22/30）in the western medication group (P<0.05). No adverse reactions occurred in both groups during treatment. CONCLUSION Hunyuan moxibustion can effectively improve the symptom severity and quality of life in patients with IBS-D of spleen and kidney yang deficiency, especially in improving the symptoms of abdominal pain, soreness and weakness of waist and knees, fear to cold and cold limbs.Its therapeutic effect is superior to western medication.

OBJECTIVE: To investigate the clinical efficacy of dexamethasone vitreous cavity implants (Ozurdex) for the treatment of macular edema (Irvine-Gass Syndrome) after cataract surgery. METHOD: Eight patients (eight eyes) with Irvine-Gass syndrome were enrolled for vitreous injections with Ozurdex. The patients included six men (six eyes) and two women (two eyes) with a mean age of 67.12 ± 11.92 years. Changes in the patients best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure were compared before and after treatment. RESULT: The mean visual acuity BCVA of the patients was 0.81 ± 0.26 before implantation, which improved to 0.20 ± 0.12, 0.13 ± 0.09, and 0.15 ± 0.13 at 2 weeks, 1 month, and 3 months after implantation, respectively ( P < 0.001). The patient's mean CMT before implantation was 703.00 ± 148.88 μm, and it reduced to 258.87 ± 37.40 μm, 236.25 ± 28.74 μm, and 278.00 ± 76.82 μm at 2 weeks, 1 month, and 3 months after implantation, respectively ( P < 0.001). CONCLUSION The dexamethasone vitreous cavity implant (Ozurdex) is a safe and effective treatment, which can effectively improve patient's visual acuity and reduce macular edema associated with cataract surgery.

PURPOSE: To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS: A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS: There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.
