OBJECTIVE: Meta-analysis of the clinical efficacy of plate and external fixator fixation in the treatment of AO-C type distal radius fractures. METHODS: PubMed, Embase, Cochrane Medical Library, Web of Science, CNKI, Wanfang, VIP and SinoMed databases were searched for all literature on randomized controlled clinical trials of AO-C distal radius fractures. The search time limits were from each database. The database will be established until June 30, 2023. The included studies were extracted according to the Cochrane Handbook (Version 6.3, 2022) for information extraction and literature quality evaluation. RevMan 5.4 was used to evaluate the risk of Publication bias, test heterogeneity and Perform Meta-analysis. The outcome indicators were:imaging anatomy indicators (volar inclination angle, ulnar deviation angle, radial height), wrist joint mobility (flexion, extension, rotation, ulnar deviation), complication rate, and comparison of surgical treatments (operative blood loss, operation time, hospitalization time, fracture healing time) and wrist joint function scores and related scales. RESULTS: (1) A total of 28 studies were included, with a total of 2 192 patients, including 1 096 cases in the plate internal fixation group and 1 096 cases in the external fixation group.(2) Meta analysis results showed:the surgical treatment situation of the external fixation group:surgical blood loss MD=-37.93, 95%CI(-48.54, -27.31), P<0.000 01;operation time MD=-31.58, 95%CI(-48.96, -14.20), P<0.000 4;hospitalization time MD=-4.58, 95%CI(-5.44, -3.71), P<0.000 01;the fracture healing time MD=-0.88, 95%CI(-1.35, -0.41), P<0.000 2, which were significantly better than that of the plate internal fixation group(P<0.05).(3) The two groups:palmar inclination angle MD=-0.17, 95%CI(-0.95, 0.61), P=0.68;ulnar declination MD=0.22, 95%CI(-0.73, 1.17), P=0.65, radial height MD=-0.24, 95%CI(-1.15, 0.67), P=0.60;flexion and extension MD=-5.63, 95%CI(-11.85, 0.58), P=0.08;rotation MD=-5.80, 95%CI(-12.77, 1.17), P=0.10, radioulnar deviation MD=-2.86, 95%CI(-10.87, 5.15), P=0.48;complication rate RR=0.96, 95%CI(0.63, 1.46), P=0.83;Gartland-Werley clinical wrist score MD=0.13, 95%CI(-0.80, 1.06), P=0.78;excellent and good rate of Gartland-Werley wrist clinical score RR=0.93, 95%CI(0.87, 1.01), P=0.08;excellent and good rate of Cooney wrist score RR=0.99, 95%CI(0.62, 1.59), P=0.98;wrist DASH score MD=-4.67, 95%CI(-14.96, 5.62), P=0.37;the differences were not significant (P>0.05). CONCLUSION Compared with internal fixation with plate, external fixation can significantly reduce the amount of surgical bleeding, shorten the operation time, hospitalization time and fracture healing time, and its imaging anatomical indicators, wrist mobility, and complications can be significantly reduced in treating AO-C distal radius fractures. Rates and wrist function scores were equivalent.

Mitochondrial DNA (mtDNA) acts as a damage-associated molecular pattern to activate the stimulator of interferon genes (STING) signaling in macrophages, promoting tissue inflammation. However, its role in acute myocardial infarction (AMI) remains unclear. Macrophage-specific Sting1 knockout mice were used to validate STING's pathological role in AMI. Cardiac and liver mtDNA were used to activate macrophages in co-culture systems with cardiomyocytes to assess fibrosis and hypertrophy. Panaxatriol saponin (PTS) was tested for its ability to block mtDNA-driven macrophage activation and subsequent cardiomyocyte damage. STING-PTS binding ability was analyzed. AMI rats received PTS to evaluate its effects on myocardial inflammation and ventricular remodeling. In vivo, macrophage-specific Sting1 knockout reduced myocardial inflammation and injury after AMI. In vitro, mtDNA-activated macrophages induced cardiomyocyte fibrosis and hypertrophy through STING signaling. PTS suppressed mtDNA-driven macrophage activation by directly binding STING, thereby blocking inflammatory cascades. In AMI rats, PTS treatment attenuated acute inflammation and reversed ventricular remodeling. These findings establish the mtDNA-STING axis in macrophages as a critical driver of post-AMI inflammation and identify pharmacological STING inhibition with PTS as a promising therapeutic strategy. The study bridges genetic validation with translational applications, highlighting macrophage STING as a novel target for ischemic heart disease management.

Objective·To develope an auditory brainstem implant(ABI)vocoder based on cochlear implant(CI)vocoder characteristics and ABI electrode array topology,and to verify its reliability.Methods·An"n-of-m"coding strategy CI/ABI vocoder was constructed based on MATLAB.Within each frame,only the envelopes of the n channels with the highest energy were selected.The interaction coefficient(IC)(range:1?3),channel numbers(range:5?22),and electrode array topology(CI/ABI)were adjustable parameters,allowing for the synthesis of simulated speech.Psychoacoustic evaluation was employed,recruiting normal hearing subjects to perform closed-set simulated phoneme perception.The phoneme recognition accuracy(20 vowel questions/condition,11 consonant questions/condition)was compared with the corresponding conditions of CI and ABI from reference literature to determine the IC value of the vocoder and verify its reliability.Results·The vocoder successfully synthesized all test stimuli.In the closed-set CI-simulated speech recognition,the simulated vowel and consonant recognition accuracy for IC2 and IC3 conditions showed no significant difference compared to the accuracy reported in the CI reference literature(P＞0.05).The difference in vowel and consonant accuracy between IC2 and the literature was smaller than that between IC3 and the literature(vowel|d|=1.6%vs.20%,consonant|d|=8.4%vs.9.9%),thus determining the optimal interaction coefficient of this model as 2.Subsequently,when modifying the electrode array topology to ABI,it was found that the simulated phoneme recognition accuracy for a 16-channel ABI was significantly lower than that for the 16-channel CI group,consistent with the reported literature.The simulated vowel and consonant accuracy within the 5?8 channel range for ABI showed no significant difference(P＞0.05),also aligning with the trend reported in the literature.Conclusion·A CI/ABI vocoder based on"n-of-m"coding strategy is established and the optimal IC is determined.The established ABI encoder has been evaluated for high reliability through psychoacoustic experiments.It provides suitable technical means for validating ABI-specific coding strategies.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective This study aimed to investigate the lipid-lowering activity of LFBEP-C1 in high glucose-fed Caenorhabditis elegans(C.elegans). Methods In this study,the fermented barley protein LFBEP-C1 was prepared and tested for its potential anti-obesity effects on C.elegans.The worms were fed Escherichia coli OP50(E.coli OP50),glucose,and different concentrations of LFBEP-C1.Body size,lifespan,movement,triglyceride content,and gene expression were analyzed.The results were analyzed using ANOVA and Tukey's multiple comparison test. Results Compared with the model group,the head-swing frequency of C.elegans in the group of LFBEP-C1 at 20 μg/mL increased by 33.88%,and the body-bending frequency increased by 27.09%.This indicated that LFBEP-C1 improved the locomotive ability of C.elegans.The average lifespan of C.elegans reached 13.55 days,and the body length and width of the C.elegans decreased after LFBEP-C1 intake.Additionally,LFBEP-C1 reduced the content of lipid accumulation and triglyceride levels.The expression levels of sbp-1,daf-2,and mdt-15 significantly decreased,while those of daf-16,tph-1,mod-1,and ser-4 significantly increased after LFBEP-C1 intake.Changes in these genes explain the signaling pathways that regulate lipid metabolism. Conclusion LFBEP-C1 significantly reduced lipid deposition in C.elegans fed a high-glucose diet and alleviated the adverse effects of a high-glucose diet on the development,lifespan,and exercise behavior of C.elegans.In addition,LFBEP-C1 regulated lipid metabolism mainly by mediating the expression of genes in the sterol regulatory element-binding protein,insulin,and 5-hydroxytryptamine signaling pathways.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.

Hepatohilar cholangiocarcinoma is a common malignant tumor of the biliary system,and radical surgery is one of the important treatment methods.Due to the narrow space at the hi-lum and the high rate of anatomical variation,radical surgery is challenging.By using medical imag-ing technology and 3D reconstruction,surgeons can accurately determine the stage and classifica-tion of hilar cholangiocarcinoma preoperatively.They can assess the tumor's resectability by Ac-cording to the bile duct separation limit points(U point,P point)and anticipate the impact of portal vein,bile duct,and arterial variations on the surgical plan,thereby improving the rate of radical re-section and reducing complication rates.
