OBJECTIVE:
To observe the clinical efficacy of auricular electroacupuncture for post-stroke dysphagia in the pharyngeal phase.
METHODS:
Eighty-two patients with post-stroke dysphagia in the pharyngeal phase were randomized into an auricular electroacupuncture group (41 cases) and a swallowing electrical stimulation group (41 cases, 1 case dropped out). In the auricular electroacupuncture group, electroacupuncture was applied at auricular points, i.e. Xin (CO15) and Yanhou (TG3), using disperse-dense wave, in frequency of 2 Hz/10 Hz, 30 min a time. In the swallowing electrical stimulation group, swallowing electrical stimulation was delivered for 30 min a time. Both groups were treated once daily for 4 weeks. The functional oral intake scale (FOIS) grade, as well as the hyolaryngeal complex displacement, the pharyngeal constriction rate (PCR) and the pharyngeal delay time (PDT) under video fluoroscopic study of swallowing (VFSS) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups.
RESULTS:
Compared before treatment, the FOIS grade was improved (P<0.01), the forward and upward displacement amplitude of hyoid bone and thyroid cartilage was increased (P<0.05), and the PCR and PDT were decreased (P<0.05) after treatment in the two groups. After treatment, compared with the swallowing electrical stimulation group, the FOIS grade was superior (P<0.01), the upward displacement amplitude of hyoid bone and thyroid cartilage was larger (P<0.05) and the PCR and PDT were lower (P<0.05) in the auricular electroacupuncture group. The total effective rate was 85.4% (35/41) in the auricular electroacupuncture group, which was higher than 62.5% (25/40) in the swallowing electrical stimulation group (P<0.05).
CONCLUSION
Auricular electroacupuncture can effectively trigger pharyngeal initiation and improve post-stroke dysphagia in the pharyngeal phase.

Enzymes are widely used in chemical and pharmaceutical industries because of their advantages of high efficiency and specificity. However, the shortcomings of the free enzymes, such as poor stability and difficulty in recycling, limit their application. Therefore, the immobilization and application of enzymes have become one of the research hotspots. The selection of the immobilization carriers is a critical step in the process of enzyme immobilization. Metal-organic frameworks(MOFs), a kind of porous materials, are formed by the coordination of metal ions or metal clusters with organic ligands. As an emerging immobilization carrier, its advantages such as high porosity, strong stability, and surface modifiability make it ideal for immobilized enzyme carriers. By immobilizing the free enzyme on MOFs, the above mentioned deficiencies of the free enzymes can be effectively solved, which greatly broaden the applicable condition. Ligand fishing is a method to find receptor-specific ligands from complex components, which has the advantages of high efficiency, simple sample pretreatment and high specificity. The MOF-enzyme complex formed by enzyme immobilization can act as a "fishing rod" for ligand fishing, which can screen out the targets from the complex system of components. The complex chemical composition and various active ingredients of traditional Chinese medicine(TCM) make the ligand fishing technology to play a big role in the screening of enzyme inhibitors from TCM. And the screened enzyme inhibitors are expected to be further developed into the lead compounds with good efficacy and low adverse effects, so the immobilized enzymes of MOFs have a wide application in the screening of active ingredients from TCM. Based on this, this paper summarized the methods of immobilized enzymes of MOFs in recent years, analyzed the characteristics, advantages and disadvantages of each method, and summarized the laws of preparation conditions and mechanisms. Meanwhile, the application and future development of immobilized enzymes of MOFs in the field of enzyme inhibitor screening from TCM were also summarized and prospected, with a view to providing a reference for the development of natural ingredients and the modernization of TCM.

BACKGROUND:Berberine has the potential to induce osteogenic differentiation of various mesenchymal stem cells under normal conditions and special conditions such as high glucose,infection and inflammation.It is a natural small molecule drug that can induce bone formation in seed cells instead of growth factors,and has great application prospect in bone tissue engineering. OBJECTIVE:To review and summarize the research progress in the osteogenic mechanism and efficacy of berberine,especially its osteogenic potential under high glucose,infection and inflammation conditions,and its biological safety,so as to provide theoretical basis for its development and application in bone tissue engineering. METHODS:PubMed,WanFang,and CNKI were searched for relevant literature using the keywords of"berberine,bone defects,bone repair,bone regeneration,osteoinductive,osteoporosis,osteoblast,osteoclast,bone tissue engineering,bone,high glucose,diabetes,inflam*,infect*"in English and Chinese,respectively.A total of 105 literatures were selected for review. RESULTS AND CONCLUSION:Berberine can be used to treat multiple diseases including bone diseases,and it has the ability to promote bone regeneration.This article systematically reviews the mechanism of berberine on bone regeneration and in vivo and in vitro studies.Studies have shown that it can play a role in bone repair by promoting osteogenesis,inhibiting osteoclast formation and activity,and preventing osteoporosis.It shows excellent osteogenic differentiation potential mainly via Wnt/β-catenin,PI3K/AKT,EGFR/MEK/p38MAPK,cAMP/PKA/CREB,ERK and other signaling pathways.Berberine can also relieve the inhibition of osteogenic differentiation caused by high glucose,infection and inflammation,which provides more possibilities for the treatment of bone defects in patients with diabetes or infection and inflammation in the bone defect site.Berberine also has the advantages of low toxicity,low price,easy access(currently it can be synthesized),which is a relatively ideal bone induction potential drug.In recent years,the application of berberine in the treatment of bone defect tends to be localized,mainly through the combination with bone tissue engineering technology to improve bioavailability,and has shown good bone repair effect and excellent biological safety in animal experiments.In addition,preclinical experiments have shown splendid bone regeneration potential in the conditions of diabetes,local infection and inflammation.In the future,more studies are needed to fully reveal the osteogenic mechanism and biological safety of berberine,and seek the most suitable controlled release loading system to make artificial bone replacement materials with good mechanical strength,efficacy and biological safety.

Objective:To evaluate the practical value of the up-converting phosphor technology (UPT) in the field fast detection of plague, and to provide scientific basis for its promotion and application in the field work of plague monitoring.Methods:In September 2020, a total of 116 samples (including 4 samples for epidemic determination) were collected at the plague epidemic site in Menghai County, Yunnan Province, including 24 human blood and lymphatic fluid samples, 83 rat liver and muscle samples, and 9 rat blood samples. In March 2023, a total of 12 rat liver and muscle samples were collected from Lijiang City for on-site monitoring of plague outbreak (all of them were outbreak determination samples). All of the above samples were tested for Yersinia pestis antibody and antigen using the up-converting phosphor technology. At the same time, haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were conducted to compare the detection process and results of different experimental methods, the advantages and disadvantages of the up-converting phosphor technology for detecting Yersinia pestis were analyzed, and the feasibility of using this detection method in the field of plague epidemic monitoring was judged. Results:The plague epidemic samples site in Menghai County, Yunnan Province were tested by up-converting phosphor technology, and 19 samples were found to be positive for Yersinia pestis (1 antibody-positive and 18 antigen-positive). Among the samples determined, 4 samples with positive results of Yersinia pestis were detected by up-converting phosphor technology, and the results of their haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture were all positive. All samples from Lijiang City were tested by up-converting luminescence technology, two samples were positive for Yersinia pestis(antigen-positive). The results of haemagglutination test and real-time fluorescence quantitative PCR were positive, and one sample was positive for bacterial culture. The time required for up-converting phosphor technology, haemagglutination test, real-time fluorescence quantitative PCR, and bacterial culture were 0.5, 4.0, 2.5 and 72.0 h, respectively. Conclusions:The results of Yersinia pestis detection by up-converting phosphor technology are basically consistent with the results of haemagglutination test, real-time fluorescence quantitative PCR and bacterial culture, but the time used is relatively short. When the number of samples is large, this method can be used preferentially in the field work of plague outbreak monitoring, which can quickly complete the preliminary judgement of plague outbreak, and save a lot of time and economic resources for the next step of plague prevention and control work.
