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.

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.

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.

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.

AIM: To investigate the efficacy and safety of paclitaxel albumin assisted platinum chemotherapy in the treatment of recurrent and metastatic cervical cancer based on tumor factors and inflammatory status. METHODS: A total of 100 patients with recurrent and metastatic cervical cancer in our hospital from January 2020 to January 2023 were randomly divided into two groups: 50 patients in the control group were treated with paclitaxel-assisted nedaplatin regimen, and 50 patients in the study group were treated with paclitaxel-assisted nedaplatin regimen. The short-term efficacy, tumor factors, inflammatory factors, relapse-metastasis related indexes, quality of life, functional status and adverse reactions were compared between the two groups. RESULTS: The total remission rate of the study group (72.00%) was higher than that of the control group (48.00%) (P<0.05). In the study group, after one and three cycles of treatment, serum cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carbohydrate antigen 724 (CA724), squamous cell carcinoma antigen (SCC Ag), interleukin-4 (IL-4), interleukin-6 (IL-6), tumor necrosis factor - α (TNF-α) The levels of serum microrna-367 (mir-367), microrna -383 (mir-383), quality of life (QOL) and Karnofsky functional status score (KPS) in the tumor patients were significantly higher than those in the control group (P<0.05); There was no significant difference in the incidence of nausea / vomiting, diarrhea, fatigue, leukopenia and allergic reactions between the study group and the control group during treatment (P>0.05), but the total incidence of adverse reactions (12.00%) was lower than that of the control group (32.00%) (P<0.05). CONCLUSION: Paclitaxel albumin-assisted nedaplatin has a reliable effect in the treatment of recurrent and metastatic cervical cancer, which can further reduce the level of tumor factors, relieve inflammation, and has high safety.
