Objective:This study aims to analyze the threshold changes in distortion product otoacoustic emissions（DPOAE） and auditory brainstem response（ABR） in adult Otof-/- mice before and after gene therapy, evaluating its effectiveness and exploring methods for assessing hearing recovery post-treatment. Methods:At the age of 4 weeks, adult Otof-/- mice received an inner ear injection of a therapeutic agent containing intein-mediated recombination of the OTOF gene, delivered via dual AAV vectors through the round window membrane（RWM）. Immunofluorescence staining assessed the proportion of inner ear hair cells with restored otoferlin expression and the number of synapses.Statistical analysis was performed to compare the DPOAE and ABR thresholds before and after the treatment. Results:AAV-PHP. eB demonstrates high transduction efficiency in inner ear hair cells. The therapeutic regimen corrected hearing loss in adult Otof-/- mice without impacting auditory function in wild-type mice. The changes in DPOAE and ABR thresholds after gene therapy are significantly correlated at 16 kHz. Post-treatment,a slight increase in DPOAE was observeds,followed by a recovery trend at 2 months post-treatment. Conclusion:Gene therapy significantly restored hearing in adult Otof-/- mice, though the surgical delivery may cause transient hearing damage. Precise and gentle surgical techniques are essential to maximize gene therapy's efficacy.

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery.Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients,and is widely recommended as a first-line clinical treatment.But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices.To address this issue,this consensus,based on a comprehensive literature review and clinical experiences of experts,systematically summarizes the indications,target patients,and contraindications of minimally invasive tooth extraction,the overall workflow of this procedure(preoperative preparation,surgical steps,postoperative management,postoperative instructions,medications,and follow-up),and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Objective To analyze the impact of mini plate and cannulated screw internal fixation on joint function recovery in patients with posterior malleolus fracture.Methods A total of 150 patients with posterior malleolus fractures,treated at our hospital from March 2021 to June 2023,were included in this study.They were divided into two groups using the odd-even number method.The control group consisted of 75 patients who underwent cannulated screw internal fixation,while the study group comprised 75 patients who received mini plate internal fixation.Clinical indicators,ankle range of motion,ankle function,and health status were compared and analyzed between the two groups.Additionally,levels of inflammatory factors,postoperative complications,and clinical efficacy were assessed.Results In terms of operation time and intraoperative blood loss,there was no statistically significant difference between the two groups(P＞0.05).However,the study group exhibited shorter ambulation days,fracture healing time,and hospitalization days compared to the control group(P＜0.05).Moreover,the study group demonstrated significantly improved ankle dorsiflexion,ankle plantar flexion,foot varus and foot valgus range of motion compared to the control group(P＜0.05).Additionally,higher AOFAS score and KPS score were observed in the study group as compared to the control group(P＜0.05).Furthermore,levels of IL-6,IL-8 and CRP were lower in the study group than in the control group(P＜0.05).The incidence of postoperative complica-tions was also lower in the study group than in the control group(P＜0.05).Conclusion Mini plate internal fixa-tion for posterior malleolus fracture yields ideal outcomes by promoting improvement in clinical indicators and ankle range of motion while effectively enhancing ankle function,reducing inflammatory reaction as well as minimizing postoperative complications.

Objective To investigate the predictive value of procalcitonin(PCT),interleukin-6(IL-6),heparin binding protein(HBP),and C-reactive protein(CRP)in cerebral infarction(CI)complicated with pulmonary infection.Methods 145 CI patients treated in Jiangning Hospital Affiliated to Nanjing Medical University from July 2022 to June 2023 were selected as the CI group.Ac-cording to whether combined with pulmonary infection,they were divided into the co-infected group(n=76)with pulmonary infection and the simple CI group(n=69)without pulmonary infection.61 healthy volunteers performed physical examination in our hospital at the same time were enrolled as the control group.The general clinical data from each group were collected and their serum biochemical indicators were compared.The multivariate Logistic regression was used to analyze the risk factors of CI complicated with pulmonary in-fection and the receiver operating characteristic(ROC)curve was constructed.The area under the ROC curve(AUCROC)was used to evaluate the diagnostic value of each index for CI complicated with pulmonary infection.Results Age,PCT,IL-6,HBP,and CRP were the independent risk factors of CI complicated with pulmonary infection(P＜0.05).The ROC curve analysis showed that each in-dex of PCT,IL-6,HBP,and CRP had a certain value in predicting CI combined with pulmonary infection.The sensitivity and specific-ity of the combination detection of PCT,IL-6,HBP,and CRP were 85.47%and 75.36%,respectively,which were significantly high-er than that of the single detection of PCT,IL-6,HBP,and CRP(P＜0.05).Conclusion The levels of serum PCT,IL-6,HBP,and CRP are highly expressed in CI patients combined with pulmonary infection.They can be used for the diagnosis of CI combined with pulmonary infection.The combination detection of the four indexes can effectively improve the diagnosis accuracy of CI complicated with pulmonary infection.

Objective To systematically analyze the current status of outcomes reporting in clinical trials on treating stasis acute mastitis with Traditional Chinese Medicine breast massage.Methods We searched CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, Embase, Cochrane library, JBI, CINAHL, PsycINFO, Clinical Trials Registry Platform portal, Clinical Trials Registry, Australian New Zealand Clinical Trials Registry, Center Watch Registry from inception to May 15, 2022 to find randomized controlled trials, non-randomized controlled trials, case series and cohort studies which reported the outcomes of stasis acute mastitis managed with Traditional Chinese Medicine breast massage, with search terms of mastitis, acute mastitis, lactation mastitis, puerperal mastitis, breast problem, breast engorgement, milk stasis, blocked ducked, breast pain, breast massage, and acupoint massage. Outcomes and the measurement schemes (measurement methods, timing of assessing outcome, frequency of assessing outcome, measurers) were extracted from the included studies. We used the Management of Otitis Media with Effusion in Children with Cleft Palate (MOMENT) to assess the quality of each study, then categorized outcomes derived from the included studies into different domains according to the Outcome Measures in Rheumatology Arthritis Clinic Trials (OMERACT) Filter 2.1 framework.Results We identified 85 clinical trials, in which 54 different outcomes were reported. A total of 81.2% (69/85) of studies were assessed as medium quality with a mean score of 2.6, and 18.8% (16/85) as low quality with a mean score of 0.9. These outcomes were organized in three core areas. Lump size (89.4%, 76/85) was the most frequently reported outcome, followed by breast pain (69.4%, 59/85) and milk excretion (68.2%, 58/85). Five methods were used to assess lump size and four methods to assess breast pain.Conclusions The outcomes reported in clinical trials regarding stasis acute mastitis treated by Traditional Chinese Medicine breast massage are heterogeneous. Developing a core outcome set to achieve consistent standards for reporting outcomes and modalities for validation of the outcomes is clearly warranted.

Coronary heart disease (CHD) and stroke are the most well-known cardiovascular diseases, which share many common pathological basis. Yindan Xinnaotong soft capsule (YDXNT) is a commonly used Chinese patent medicine in the treatment of stroke and CHD. However, its action of mechanism of co-treatment for stroke and CHD is still unclear. The aim of this study was to explore the common mechanism of YDXNT in co-treatment of CHD and stroke using network pharmacology, experimental verification and molecular docking. An integrated literature mining and databases of IPA, ETCM, HERB, Swiss Target Prediction, OMIM and GeneCards were used to screen and predict active ingredients and potential targets of YDXNT in co-treatment of CHD and stroke. The protein-protein interaction network, GO analysis and pathway analysis were analyzed by IPA software. The effect of YDXNT on core targets was verified by immunofluorescence. UPLC-QTOF/MS and molecular docking were used to screen and predict the main active constituents of YDXNT and their interactions with core targets. A total of 151 potential targets are predicted for YDXNT in co-treatment of CHD and stroke. Hypoxia-inducible factor-1α (HIF1α)-matrix metalloproteinase-9 (MMP9)-mediated HIF1α signaling pathway serves as one of the common mechanisms. YDXNT could reduce the increase of mitochondrial fluorescence intensity and the protein expression of HIF1α and MMP9 in HL-1 and HA induced by oxygen and glucose deprivation/reperfusion (OGD/R) in a dose-dependent manner. Baicalin may be the material basis for treating stroke and CHD with YDXNT. In conclusion, the HIF1α signaling pathway is one of the common key mechanisms of YDXNT in the co-treatment of stroke and CHD. The study provides support and basis for the in-depth scientific connotation of the traditional Chinese medicine theory of "same treatment to different diseases".

BACKGROUND: Cholecystectomy is a standard surgery for patients suffering from gallbladder diseases, while the causal effects of cholecystectomy on colorectal cancer (CRC) and other complications are still unknown. METHODS: We obtained genetic variants associated with cholecystectomy at a genome-wide significant level ( P value <5 × 10 -8 ) as instrumental variables (IVs) and performed Mendelian randomization (MR) to identify the complications of cholecystectomy. Furthermore, the cholelithiasis was also treated as the exposure to compare its causal effects to those of cholecystectomy, and multivariable MR analysis was carried out to judge whether the effect of cholecystectomy was independent of cholelithiasis. The study was reported based on Strengthening the Reporting of Observational Studies in Epidemiology Using Mendelian Randomization guidelines. RESULTS: The selected IVs explained 1.76% variance of cholecystectomy. Our MR analysis suggested that cholecystectomy cannot elevate the risk of CRC (odds ratio [OR] =1.543, 95% confidence interval [CI]: 0.607-3.924). Also, it was not significant in either colon or rectum cancer. Intriguingly, cholecystectomy might decrease the risk of Crohn's disease (OR = 0.078, 95% CI: 0.016-0.368) and coronary heart disease (OR = 0.352, 95% CI: 0.164-0.756). However, it might increase the risk of irritable bowel syndrome (IBS) (OR = 7.573, 95% CI: 1.096-52.318). Cholelithiasis could increase the risk of CRC in the largest population (OR = 1.041, 95% CI: 1.010-1.073). The multivariable MR analysis suggested that genetic liability to cholelithiasis could increase the risk of CRC in the largest population (OR = 1.061, 95% CI: 1.002-1.125) after adjustment of cholecystectomy. CONCLUSIONS The study indicated that cholecystectomy might not increase the risk of CRC, but such a conclusion needs further proving by clinical equivalence. Additionally, it might increase the risk of IBS, which should be paid attention to in clinical practice.

We reported the discovery of six novel coumarins, toddasirins A-F (1-6), each endowed with modified isoprenyl or geranyl side chains, derived from the roots of Toddalia asiatica. Comprehensive structural elucidation was achieved through multispectroscopic analyses, single-crystal X-ray diffraction experiments, and advanced quantum mechanical electronic circular dichroism (ECD) calculations. Furthermore, the anti-inflammatory activity of these compounds was assessed. Notably, compounds 1-3 and 6 demonstrated notable inhibitory effects on nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW 264.7 cells, with 50% inhibitory concentration (IC₅₀) values of 3.22, 4.78, 8.90, and 4.31 μmol·L^-1, respectively.
