OBJECTIVE: To provide the experience and demonstration for the transformation of acupuncture-moxibustion techniques standards from Chinese national standards to international standards. METHODS: Questionnaire research, literature research, semi-structured interviews and expert consultation were used. RESULTS: The safety of acupuncture-moxibustion techniques was evaluated through literature research, and based on the results of the questionnaire survey, expert interviews, and expert consultation, 11 main bodies and structure of the former Chinese national standard, Technical Benchmark of Acupuncture and Moxibustion: General Rules for Drafting, were adjusted and optimized in accordance with the requirements of international standard (including the language, normative references, purpose, scope, applicable environment, target population, work team, terms and definitions, general principles and basic requirements, structural elements and text structure, and compilation process); and the first international standard, World Federation of Acupuncture-Moxibustion Societis (WFAS) Technical Benchmark of Acupuncture and Moxibustion: General Rules for Drafting was formulated to specify the general rules for drafting. CONCLUSION The 3 key questions, "international compatibility", "technical operability" and "safety" should be solved technically on the basis of explicit international requirements. It is the core technical issue during transforming the national standards of technical benchmark of acupuncture and moxibustion into international standards.

Mechanical pain is one of the most common causes of clinical pain, but there remains a lack of effective treatment for debilitating mechanical and chronic forms of neuropathic pain. Recently, neurotoxin GsMTx4, a selective mechanosensitive (MS) channel inhibitor, has been found to be effective, while the underlying mechanism remains elusive. Here, with multiple rodent pain models, we demonstrated that a GsMTx4-based 17-residue peptide, which we call P10581, was able to reduce mechanical hyperalgesia and neuropathic pain. The analgesic effects of P10581 can be as strong as morphine but is not toxic in animal models. The anti-hyperalgesic effect of the peptide was resistant to naloxone (an μ-opioid receptor antagonist) and showed no side effects of morphine, including tolerance, motor impairment, and conditioned place preference. Pharmacological inhibition of TRPV4 by P10581 in a heterogeneous expression system, combined with the use of Trpv4 knockout mice indicates that TRPV4 channels may act as the potential target for the analgesic effect of P10581. Our study identified a potential drug for curing mechanical pain and exposed its mechanism.

Objective:To investigate the clinical and electroencephalogram (EEG) characteristics of pattern-sensitive epilepsy (PSE).Methods:This retrospective case summary study enrolled 4 pediatric patients with PSE treated at the Peking University People′s Hospital from January 2015 to September 2023.The clinical data, EEG findings, treatments, and prognosis were retrospectively analyzed.Results:Among the 4 patients, 3 were female, and 2 had developmental delays before the onset of the disease.Spontaneous seizures occurred in 3 cases, including spasticity and tonic seizures in case 1, atypical absence seizures, myoclonic seizures, and general tonic-clonic seizures in case 3, and eyelid myoclonic seizures in case 4.All 4 cases exhibited pattern-induced reflex seizures, and pattern-induced seizures with photosensitivity were monitored by EEG in 3 cases.Of the 3 cases, 1 had myoclonic seizures, 1 had eyelid myoclonic seizures, and 1 had both myoclonic seizures and focal to bilateral tonic-clonic seizures.Two out of the 4 patients were diagnosed with epilepsy syndromes: Lennox-Gastaut syndrome and epilepsy with eyelid myoclonia.All 4 patients had interictal discharges, including 2 cases of generalized discharges, 1 case of multifocal discharges combined with generalized discharges, and 1 case of anterior head discharges.Three cases underwent the detection of whole exon gene and copy number variation, and 1 case showed a novel heterozygous mutation c. 73T>C(p.W25R) in the MBD5 gene on chromosome 2.Three patients were treated with antiseizure medication (ASM), while 1 did not receive ASM treatment because the seizures were all induced.However, none of the 4 had seizures under control after 5 to 10 years of follow-up. Conclusions:PSE is more common in female children and may co-occur with developmental delays and intellectual disabilities.In PSE children, the EEG shows mostly generalized discharges, spontaneous seizures, induced seizures, and predominantly generalized seizures coexist.Reflex seizures in PSE patients are more difficult to control with ASM treatment.

Objective:To investigate the correlation between the levels of CC chemokine ligand 2 (CCL2) and periostin (POSTN) in serum and alveolar lavage fluid of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) complicated with respiratory virus infection and lung function.Methods:From March 2020 to March 2023, 96 patients with acute exacerbation of COPD admitted to our hospital were collected. Among them, 34 patients with concurrent respiratory virus infection were included in the infected group, and 62 patients without respiratory virus infection were included in the uninfected group. Enzyme linked immunosorbent assay (ELISA) was applied to detect the expression levels of CCL2 and POSTN in serum and alveolar lavage fluid. Pearson method was applied to analyze the correlation between CCL2 and POSTN levels in serum and alveolar lavage fluid of infected patients and lung function indicators.Results:The levels of CCL 2 ( t=12.633, 9.253 2, 2) and POSTN ( t=12.370, 7.383) were significantly increased in the infected group compared with the uninfected group ( P<0.05). Compared with the uninfected group, the 6-minute walking test (6 MWT), peak expiratory flow rate (peak expiratory flow, PEF), forced expiratory volume at the first second (forced expiratory volume in one second, FEV 1), and the forced lung capacity (forced vital capacity, FVC), FEV 1/FVC, and maximum middle breath mean flow rate (maximal mid-expiratory flow curve, MMEF) were significantly lower ( t=14.141, 24.165, 22.421, 21.223, 5.278, 29.456, P<0.05). Correlation analysis showed that the levels of CCL2 and POSTN in the serum and alveolar lavage fluid of the infected group were negatively correlated with the levels of 6MWT, PEF, FEV1, FVC, FEV1/FVC, and MMEF ( P<0.05). Conclusions:CCL2 and POSTN levels were highly expressed in serum and alveolar lavage fluid of patients with respiratory virus infection during acute exacerbation of COPD, which were closely related to lung function.

Root canal therapy is the primary treatment method for pulpal and periapical diseases.Various advanced endodontic instruments for mechanical preparation have been marketed.The emergence of nickel-titanium rotary instru-ments has greatly improved the efficiency of root canal preparation.New demands have been put forward for nickel-tita-nium rotary instruments as a result of the deepening of clinicians'awareness of root canal anatomy system as well as the purpose and prognosis of root canal treatment.These clinical-oriented demands accelerate instrument reform and innova-tion.This work presents new marketed nickel-titanium systems and discusses the advantages and limitations of these sys-tems and how they perform in terms of the efficiency and outcome of root canal preparation.

Objective:To determine the effects of early enteral nutrition (EEN) on the short-term prognosis of patients receiving veno-arterial extracorporeal membrane oxygenation (VA-ECMO).Methods:61 patients admitted to the Coronary Care Unit (CCU) of Henan Provincial Peoples' Hospital from February 2022 to March 2023 to receive VA-ECMO treatment were selected as the study objects according a retrospective survey. The patients were divided into an achievement group ( n=34) and a non-achievement group ( n=27) based on whether the feeding amount reached 70% or over of the target calories (25kcal/kg.d) on the 7th day of ECMO treatment. The general characteristics, disease information, complications, and prognosis between the two groups after ICU admission were recorded and compared. A multivariable Cox proportional hazards model was used to evaluate the impact of various factors on clinical outcomes. Kaplan-Meier analysis was used to draw survival curves for the two groups, and the predictive value of the ratio of actual EN intake to target energy was calculated by plotting the ROC curve. Results:A total of 61 patients were included, with an overall in-hospital mortality rate of 50.82% (31/61), with 32.35% (11/34) in the achievement group, and 70.37% (19/27) in the non-achievement group. Cox regression analysis revealed that the occurrence of hypoxic-ischemic encephalopathy (HR=0.341, 95% CI:0.119-0.975), ECOM weaning failure ( HR=0.269, 95% CI:0.111-0.651), and achieving EN targets on the 7th day of VA-ECMO treatment ( HR=10.891, 95% CI:1.178-100.718) were independent factors for patient mortality during hospitalization. The ROC curve for the percentage of EN achievement on the 7th day of VA-ECMO treatment and in-hospital mortality showed an area under the curve of 0.755, with a cutoff value of 0.73. Conclusion:The presence of ischemic hypoxic encephalopathy, ECOM weaning failure, and whether achieving EN targets or not is closely related to the prognosis of VA-ECMO patients. Patients who achieving EN targets of over 73% had the lowest in-hospital mortality rate. Therefore, more attention should be paid to the energy intake of VA-ECMO patients to reduce their risk of mortality.

Objective:To investigate the application value of virtual reality laparoscopic simulator training in laparoscopic transabdominal preperitoneal hernioplasty (TAPP).Methods:The prospective cohort study was conducted. Twenty young physicians from The First Affiliated Hospital of Harbin Medical University with ≥3 years of clinical experience in general surgery and no foundation in laparoscopy were selected for training during July to August 2023. Physicians were divided into two groups based on random number table method. Physicians undergoing virtual reality laparoscopic simulator training were divided into the virtual reality group, and physicians undergoing regular laparoscopic simulator training were divided into the regular group. Two groups of physicians were trained using laparoscopic simulator for 10 days (2 hours for each skill, with a total of 6 hours per day for 3 skills), and the training covered basic laparoscopic surgical skills such as clamping, cutting and suturing and knotting. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups were conducted using the independent sample t test and the paired ttest was used for intra group comparison. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test. Results:(1) Physicians situation before training. A total of 20 physicians were selected for eligibility. There were 13 males and 7 females, aged 31(range, 30?34)years. There are 7 males and 3 females in the virtual reality group, with age of (31.5±1.4)years and the TAPP simulation surgery time of (42±4)minutes before training. There are 6 male and 4 female students in the regular group, with age of (31.2±1.0)years and the TAPP simulation surgery time of (42±4)minutes before training. There was no significant difference in gender, age, TAPP simulation surgery time between the two groups of physicians ( P>0.05), confounding bias ensured comparability. (2) Basic skills of physicians before and after training. For physicians in the virtual reality group, the clamping score was 5.1±1.0, the cutting score was 4.9±1.0, the suturing and knotting score was 4.7±1.5 before training. The clamping score was 8.0±1.3, the cutting score was 7.9±1.5, the suturing and knotting score was 6.6±1.3 after training. There were significant differences in the above indicators before and after training ( t=?5.75, ?5.21, ?3.07, P<0.05). For physicians in the regular group, the clamping score was 5.3±1.0, the cutting score was 5.0±1.2, the suturing and knotting score was 4.3±1.5 before training. The clamping score was 7.1±1.2, the cutting score was 6.7±1.3, the suturing and knotting score was 5.7±1.1 after training. There were significant differences in the above indicators before and after training ( t=?3.73, ?3.16, ?2.42, P<0.05). (3) Completion of simulated surgical situations before and after training. The time of completing TAPP simulation surgery for virtual reality group after training was (29±3)minutes, versus (42±4)minutes before training, showing a significant difference before and after training ( t=7.69, P<0.05). The time of completing TAPP simulation surgery for regular group after training was (36±4)minutes, versus (42±4)minutes before training, showing a significant difference before and after training ( t=3.75, P<0.05). The time of completing TAPP simulation surgery of virtual reality group after training was shorter than that of regular group, showing a significant difference between the two groups ( t=?3.89, P<0.05). Conclusion:Both of virtual reality and regular laparoscopic simulator can enhance the basic laparoscopic surgical skills and the proficiency of TAPP simulation surgery of physicians, and the training effect of virtual reality laparoscopic simulators is better.
