OBJECTIVE: To observe the effect of the direct stimulation of acupuncture at extraocular muscle attachment point on acquired extraocular muscle palsy. METHODS: Thirteen patients with acquired extraocular muscle palsy were treated with acupuncture directly at extraocular muscle (paralytic muscle) attachment point. Firstly, the intraocular conjunctival sac drops of topical anesthetic (procaine hydrochloride eye drops) were administered, 0.2 mL each time, once every 10 minutes, for a total of 3 times. Acupuncture was delivered immediately after the third drop. The sterile acupuncture needle for single use, 0.25 mm×25 mm, was inserted at the anatomical location of the corneal limbal attachment of paralytic extraocular muscle, with an angle of 10° to 15° formed between the needle tip and extraocular muscle, and a depth of 0.3 mm to 0.5 mm. Pivoted by the needle tip, the eyeball was moved passively towards the direction of normal action of orbital muscle, 30 to 50 times until the patient felt soreness of the eyeball; afterwards, the needle was removed. After acupuncture, levofloxacin eye drops were administered once (0.2 mL) at the affected eye. The treatment was given twice a week, and completed when diplopia disappeared. Before and after treatment, the diplopia and the synoptophore circumference were observed respectively. RESULTS: After 7 to 24 (15.46±5.56) times of direct stimulation with acupuncture at extraocular muscle attachment point, the symptoms of diplopia disappeared in 13 patients, the eye position restored to orthophoria, and the circumference of synoptophore was reduced to be (4.04±0.82)° from (19.38±3.98)° detected before treatment (P<0.05). CONCLUSION Acupuncture directly at extraocular muscle attachment can attenuate diplopia and improve ocular muscle function in patients with acquired extraocular muscle palsy.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

BACKGROUND: Owing to the high prevalence of antibiotic resistance in Helicobacter pylori ( H. pylori ) in China, bismuth-containing quadruple therapies have been recommended for H. pylori eradication. This study compared the efficacy and safety of quadruple regimens containing vonoprazan vs . esomeprazole for H. pylori eradication in a patient population in China. METHODS: This was a phase 3, multicenter, randomized, double-blind study. Patients with confirmed H. pylori infection were randomized 1:1 to receive quadruple therapy for 14 days: amoxicillin 1000 mg and clarithromycin 500 mg after meals, bismuth potassium citrate 600 mg before meals, plus either vonoprazan 20 mg or esomeprazole 20 mg before meals, all twice daily. The primary outcome was the eradication rate of H. pylori , evaluated using a 13 C urea breath test at 4 weeks after treatment. The non-inferiority margin was at 10%. RESULTS: The study included 510 patients, 506 of whom completed the follow-up assessment. The primary analysis revealed eradication rates of 86.8% (210/242) and 86.7% (208/240) for vonoprazan and esomeprazole therapy, respectively (treatment difference: 0.1%; 95% confidence interval [CI]: -5.95, 6.17; non-inferiority P  = 0.0009). Per-protocol analysis showed eradication rates of 87.4% for vonoprazan and 86.3% for esomeprazole (treatment difference: 1.2%; 95% CI: -5.03, 7.36; non-inferiority P  = 0.0004). Vonoprazan and esomeprazole were well tolerated, with similar safety profiles. CONCLUSION: Vonoprazan was found to be well-tolerated and non-inferior to esomeprazole for eradicating H. pylori in patients from China. TRIAL REGISTRATION ClinicalTrials.gov , NCT04198363.

In China, the crude oil supply is highly dependent on overseas countries, and thus strengthening crude oil self-sufficiency has become an important issue of the national energy security. Tertiary oil recovery, especially polymer flooding, has been widely applied in large oil fields in China, which can increase the recovery rate by 15%-20% compared with water flooding. However, the widely used oil flooding polymers show poor thermal stability and salinity tolerance, complicated synthesis ways of monomers, and environmental unfriendliness. Moreover, the polymer flooding induces problems including pore plugging, heterogeneity intensification, high dispersion of remaining oil resources, pressure rise in injection wells, and low efficiency circulation of injection medium, which restrict the subsequent recovery of old oil fields. Here, we systematically review the developing and current situations of polymer flooding, introduce the innovative biomanufacturing of oil flooding polymers and their monomers or precursors as well as low-cost bio-based chemical raw materials for multiple compound flooding. The comprehensive study of the relationships between microbial fermentation metabolites and polymer flooding will reveal the green and low-carbon paths for polymer flooding. Such study will enable the application of enzymes produced by microorganisms in polymer production and polymer plugging removal after polymer flooding as well as the application of microbial metabolites such as biosurfactants, organic acids, alcohols, biogas, and amino acids in enhancing oil recovery. This review suggests that incorporating biomanufacturing into polymer flooding will ensure the high productivity and stability for crude oil production in China.

Synthetic biology is a crucial tool for the development of the bio-industry and bio-economy, representing a significant aspect of new quality productive forces. As a core course for graduate students in bioengineering, Synthetic Biology plays a vital role in ensuring the supply of essential talents for the development of the bio-industry in the new era. To better serve regional economic development and provide high-level talents for China's progress in the bio-industry, we analyzed typical issues encountered in the past teaching activities, set up a multi-disciplinary teaching team, optimized the course contents, adjusted the teaching mode, and mobilized students' learning interest. With the application of scientific research project as the starting point, we guided students to think and discuss deeply through the simulation of application writing and project defense, which improved students' critical thinking and innovative thinking. With industrialization as a focus, we explored a new training model combining production, education, and research through the joint practice base of the university and enterprises introduced typical cases of biomanufacturing to encourage students to engage in scientific research. The teaching reform significantly enhances the comprehensive abilities and national sentiments of graduate students. This paper hopes to serve as a reference for colleagues engaged in teaching in this field.

  Objective  To promote the development of high-quality health standards in China and summarize the characteristics of global health standards management systems and development processes.  Methods  We conducted a systematic search of relevant databases and the websites of standardization institutions. A descriptive method was used to analyze the basic characteristics of the standard management systems and development processes.  Results  The majority of the investigated countries and organizations primarily implement voluntary standards, with the exception of Chinese and the European Committee for Standardization that enforce compulsory standards. All countries and organizations have health standards at the national, group, and enterprise levels. In China and Japan, standards authorities are subordinate to the government, while in other countries or organizations, they operate as independent civil societies. The development process for health standards generally involves five stages: "Project/Proposal → Draft → Enquiry → Review → Publication". However, the specific steps in the development of health standards vary across different countries and organizations. Furthermore, China ranks high in the number of both standards and health standards issued, but the proportion of health standards is only 2.06%.  Conclusions  There are significant differences between China and other countries in terms of the management system and development process of health standards. To promote the management and development of high-quality health standards in China, we recommend promoting the coordination mechanism for standard development, increasing efforts to publicize standards and evaluate the implementation effect, strengthening the construction of personnel for the development of health standards, optimizing the efficiency of standard development and improving the internationalization level of health standards.

This article employs a multidisciplinary approach encompassing traditional Chinese medicine, history, philology, and exegetics to comprehensively examine the historical evolution of auricular acupoint therapy and otomedicine. Originating in China, systematized in Europe, and currently advancing through modern research and development led by China, this study traces the historical context of otological practices. It outlines the foundational principles of otomedicine as depicted in the Huangdi Neijing, elucidates the accumulation of ancient otomedical knowledge within this framework, reviews the systematic establishment and theoretical underpinnings of auricular acupoints, and delineates the process of formulating auricular acupoint standards. Through case studies such as " ear-brain interconnection" and " ear treatment of encephalopathy", it illustrates the interdisciplinary nature of ear medicine research and development. The article aims to illuminate the historical transition from ear therapy to ear medicine within the contemporary context and the emergence of auricular point-guided ear medicine. By drawing on historical insights and looking toward the future, it provides a foundation for the ongoing development of the ear medical specialty, offering insights for integrating non-drug therapies into China′s healthcare system and global health initiatives.

Objective:To understand the epidemiology of rubella and the genetic characteristics of the virus circulating during the period 2021-2022, providing basic scientific data for rubella prevention and control in China.Methods:National rubella incidence data for the period 2021-2022 were obtained from the Infectious Disease Surveillance System module and the Surveillance Report Management module of the China′s Disease Prevention and Control Information System. Positive rubella virus(RuV)isolates were obtained from the National Measles/Rubella Laboratory Network. Two nucleotide (nt) fragments [F1-480 (8 633-9 112 nt) and F2-633 (8 945-9 577 nt)] located in the E1 gene were amplified and determined by reverse transcription polymerase chain reaction (RT-PCR), and the target gene (E1-739) was obtained after collating and splicing. The sequences obtained in this study were used to construct a phylogenetic tree with the reported reference strains for genotype and lineage identification. Additionally, the phylogenetic analysis was performed to assess their genetic relatedness of RuV strains prevalent in China during 2018-2020 from GenBank database.Results:In 2021-2022, the rubella incidence in China was 0.06/100, 000 (2021: 840 cases; 2022: 784 cases), with cases primarily concentrated in the western and southern provinces. Age distribution analysis showed that rubella cases in 2021-2022 was mainly in children under 5 years of age (2021: 34.17%, 287/840; 2022: 42.09%, 330/784), with the highest proportion in children aged 0-2 years. Further analysis of the immunization history of cases revealed that in the 8-23 months age group, a significant proportion of cases had received only one dose of rubella containing vaccine (RCV); cases in the 2-14 years age group were mainly among children who had received two or more doses of RCV; however, cases over 15 years of age were primarily found in individuals who had not received RCV or had unknown immunization history. National virological surveillance data showed that totally 22 RuV virus isolates were obtained, from 6 provinces in China during 2021-2022, which belonged to lineage 1E-L2 (11 strains) and 2B-L2c (11 strains). And these viruses displayed high genetic homology with RuV prevalent from 2018 to 2020.Conclusions:The incidence of rubella in China was maintained at a low level during 2021-2022, and the prevalent RuV strains were lineage 1E-L2 and 2B-L2c.

Objective:To investigate the feasibility,safety and effectiveness of robot-assisted laparo-scopic buccal mucosa graft ureteroplasty in the treatment of complex long proximal ureteral stricture.Methods:The clinical data of 20 patients with proximal ureteral stricture undergoing robot-assisted lapa-roscopic buccal mucosa graft ureteroplasty admitted to the Department of Urology,Peking University First Hospital and Beijing Jiangong Hospital from July 2022 to January 2023 were prospectively collected and analyzed.Intraoperative conditions,postoperative complications and follow-up data were also recorded and analyzed.Results:The operations under robot-assisted laparoscopy were performed successfully in all the 20 patients without conversion to traditional laparoscopic surgery or open surgery.The study in-cluded 14 males and 6 females with a mean age of(41±11)years(range:19 to 60 years)and a mean body mass index of(24.3±3.6)kg/m2(range:18.2 to 31.8 kg/m2).There were 9 cases on the left side and 11 cases on the right side.The strictures of all the patients were located in the proximal segment of the ureter(including the ureteropelvic junction).The mean preoperative serum creatinine was(92.2±23.3)μmol/L(range:49.2 to 138.9 μmol/L),and the mean length of ureteral stricture was(2.8±0.9)cm(range:1.0 to 4.0 cm).Ten patients had previously undergone unsuccessful reconstructive surgery.During the operation,12 patients received posteriorly augmented anastomosis with ventral onlay.The mean length of the buccal mucosa graft harvested during the operation was(3.1±0.6)cm(range:2.0 to 4.3 cm),and the median width was 1.5 cm(range:1.0 to 2.0 cm).The omentum flap was used to wrap the reconstructed ureteral segment in all the 20 cases.The median operative time was 154 min(range:113 to 300 min),and the median estimated blood loss was 45 mL(range:0 to 100 mL).The median postoperative hospital stay was 4 d(range:4 to 14 d).The mean postoperative follow-up time was(15.0±1.7)months(range:12.5 to 17.9 months),and the surgical success rate was 100.0％in this study.After surgery,11 patients reported mild discomfort at the oral donor site,2 patients deve-loped urinary tract infection,and no postoperative complications were reported in the other 7 patients.The mean serum creatinine was(90.9±23.9)μmol/L(range:60.0 to 153.0 μmol/L)six months after surgery.Conclusion:Robot-assisted laparoscopic buccal mucosa graft ureteroplasty for the treatment of complex long proximal ureteral stricture has satisfactory efficacy without severe complications,which has shown good feasibility,safety and effectiveness.However,large sample studies and long-term follow-up are still needed to evaluate its long-term efficacy.
