OBJECTIVE: To evaluate the clinical effect and safety of acupuncture manipulation on treatment of intractable facial paralysis (IFP), and verify the practicality and precision of the Anzhong Facial Paralysis Precision Scale (Eyelid Closure Grading Scale, AFPPS-ECGS). METHODS: A multicentre, single-blind, randomized controlled trial was conducted from October 2022 to June 2024. Eighty-nine IFP participants were randomly assigned to an ordinary acupuncture group (OAG, 45 cases) and a characteristic acupuncture group (CAG, 44 cases) using a random number table method. The main acupoints selected included Yangbai (GB 14), Quanliao (SI 18), Yingxiang (LI 20), Shuigou (GV 26), Dicang (ST 4), Chengjiang (CV 24), Taiyang (EX-HN 5), Jiache (ST 6), Fengchi (GB 20), and Hegu (LI 4). The OAG patients received ordinary acupuncture manipulation, while the CAG received characteristic acupuncture manipulation. Both groups received acupuncture treatment 3 times a week, with 10 times per course, lasting for 10 weeks. Facial recovery was assessed at baseline and after the 1st, 2nd and 3rd treatment course by AFPPS-ECGS and the House-Brackmann (H-B) Grading Scale. Infrared thermography technology was used to observe the temperature difference between healthy and affected sides in various facial regions. Adverse events and laboratory test abnormalities were recorded. The correlation between the scores of the two scales was analyzed using Pearson correlation coefficient. RESULTS: After the 2nd treatment course, the two groups showed statistically significant differences in AFPPS-ECGS scores (P<0.05), with even greater significance after the 3rd course (P<0.01). Similarly, H-B Grading Scale scores demonstrated significant differences between groups following the 3rd treatment course (P<0.05). Regarding temperature measurements, significant differences in temperatures of frontal and ocular areas were observed after the 2nd course (P<0.05), becoming more pronounced after the 3rd course (P<0.01). Additionally, mouth corner temperature differences reached statistical significance by the 3rd course (P<0.05). No safety-related incidents were observed during the study. Correlation analysis revealed that the AFPPS-ECGS and the H-B Grading Scale were strongly correlated (r=0.86, 0.91, 0.93, and 0.91 at baseline, and after 1st, 2nd, and 3rd treatment course, respectively, all P<0.01). CONCLUSIONS Acupuncture is an effective treatment for IFP, and the characteristic acupuncture manipulation enhances the therapeutic effect. The use of the AFPPS-ECGS can more accurately reflect the recovery status of patients with IFP. (Trial registration No. ChiCTR2200065442).

Objective: To evaluate the safety and efficacy of the emergency infusion protocol for universal red blood cells by analyzing its clinical application in patients treated at our hospital's war trauma and emergency center. Methods: Data were collected from 133 patients who received universal red blood cell transfusion in the war trauma center of our hospital from January 2016 to December 2024. The basic information, universal red blood cell transfusion volume, compatible blood components, transfusion volume, blood routine (Hb, Hct), liver and kidney function (ALT, AST, TBil, DBil, creatinine, etc.) and coagulation function (PT, APTT, Fib, etc.) before and after transfusion were retrospectively analyzed. Results: Among the 133 patients who received a total of 374 units of universal red blood cells, the 24-hour survival rate was 62.4% (83/133). Spearman correlation analysis showed a positive correlation between shock index and universal red blood cell transfusion volume (r=0.283, P<0.05). Patients were stratified by universal red blood cell transfusion volume (≤ 3 U vs ≥ 4 U). The low volume group had less homotypic red blood cell transfusion volume and total transfusion volume at different time points, and the difference was statistically significant: within 2 h [2(2, 4)vs 4(3, 7), P=0.033<0.05], 0~24 h [6(4, 9) vs 8(6, 14), P=0.028<0.05], total transfusion volume [13(8, 20)vs 19(12, 35), P=0.021<0.05]. No acute hemolytic transfusion reaction occurred within 24 hours after transfusion of universal red blood cell. Conclusion: Universal red blood cells are safe for use in emergency treatment. Furthermore, the shock index combined with the volume of universal red blood cells transfused can predict subsequent transfusion requirements and enables the early reservation of compatible blood, thereby preventing delayed resuscitation.

Objective To analyze the effect of low-dose methylprednone sodium succinate combined with erythromycin in the treatment of Mycoplasma pneumoniae infection with elevated lactate dehydrogenase(LDH)in children.Methods Children with Mycoplasma pneumoniae pneumonia(MPP)complicated with elevated LDH were divided into control group and treatment group by random number table method.The control group was given erythromycin treatment,and the treatment group was given low-dose methylprednisolone sodium succinate combined with erythromycin treatment.Clinical efficacy and clinical symptom disappearance time were recorded in both groups.Pulmonary X-ray signs,immune function[T cell subsets(CD4+,CD8+,CD4+/CD8+)],immunoglobulin(Ig)A,IgM and serum LDH were compared between the two groups before and after treatment,and the adverse drug reactions of treatment were observed.Results There were 51 cases in control group and 51 cases in treatment group.The total effective rate in treatment group was 96.00％,which was significantly higher than 81.63％in control group(P＜0.05).The fever abatement times in treatment group and control group were(4.22±0.87)and(5.46±0.98)d;cough disappearance times were(6.31±0.98)and(7.49±1.10)d;disappearance times of pulmonary rales were(7.36±1.14)and(8.61±1.23)d,all with significant difference(all P＜0.05).After treatment,the patchy infiltrating shadow sign rates in treatment group and control group were 2.00％and 16.33％;the bronchial wall thickening sign rates were 4.00％and 18.37％,all with significant difference(all P＜0.05).After treatment,IgA levels in treatment group and control group were(0.55±0.11)and(0.68±0.12)g·L-1;IgM levels were(0.90±0.19)and(1.18±0.21)g·L-1;LDH levels were(229.45±10.30)and(240.18±11.17)U·L-1,all with significant difference(all P＜0.05).The total incidence of adverse drug reactions in treatment group and control group were 6.00％and 4.08％respectively,without significant difference(P＞0.05).Conclusion Erythromycin combined with low-dose methylprednone in systemic treatment of children with MPP and elevated LDH has a significant efficacy,and it can promote the reductions of inflammation and immune disorders and accelerate the disease outcomes,and it is safe and reliable.

Objective To investigate the effects of circ_UBE2C on the proliferation and glycolysis of lung cancer cells and its mechanism of action.Methods The expression of circ_UBE2C,miR-107,and hexokinase 2(HK2)in lung cancer tissues and normal lung tissues were analyzed based on the The Cancer Genome Atlas(TCGA)database.Kaplan-Meier survival curve was plotted to analyze the correlation between circ_UBE2C/miR-107/HK2 expression and survival of the lung cancer patients.qRT-PCR was used to detect the expression of circ_UBE2C and miR-107,and Western blotting was employed to measure the expression of HK2 and PCNA in human normal lung epithelial cells(BEAS-2B)and human lung cancer cell lines(A549,NCI-H460,and NCI-H1299).Then A549 and NCI-H1299 cells were divided into the blank group(NC),circ_UBE2C knockdown group(si-circ),HK2 knockdown group(si-HK2),simultaneous knockdown of miR-107+HK2 group(miR-inhibitor+si-HK2),and simultaneous knockdown of circ_UBE2C+miR-107 group(si-circ+miR-inhibitor).CCK-8 assay and colony formation assay were employed to measure the proliferation of above cell groups.The glucose uptake,lactate generation,and ATP production in the cells were measured by glucose uptake colorimetric assay kit,lactic acid detection kit,and ATP content determination kit,respectively.Seahorse XF glycolytic stress test and Seahorse XF cellular mitochondrial stress test were respectively performed to detect the extracellular acidification ratio(ECAR)and cellular oxygen consumption ratio(OCR).The targeting relationship between the circ_UBE2C and miR-107,and miR-107 and HK2 was validated by dual-luciferase reporter gene assay.Results Compared with normal lung tissues,the expression of circ_UBE2C and HK2 was up-regulated,while that of miR-107 was down-regulated in lung cancer tissues(P＜0.05).The expression of circ_UBE2C and HK2 was elevated,and that of miR-107 was reduced in A549 and NCI-H1299 cells when compared with BEAS-2B cells(P＜0.05).Survival analysis showed that the patients with high expression of circ_UBE2C and HK2 or low expression of miR-107 had shorter survival(P＜0.05).Compared with the NC group,both si-circ and si-HK2 resulted in significantly reduced proliferation,glucose uptake,lactate generation,ATP production,and ECAR and OCR values in A549 and NCI-H1299 cells(P＜0.05).Dual luciferase reporter gene assay confirmed that circ_UBE2C could directly bind to and negatively regulate miR-107 expression.HK2 was then identified as a downstream target of miR-107.Compared with the si-HK2 group,the proliferative ability and glycolysis level of A549 and NCI-H1299 cells were significantly increased in the miR-inhibitor+si-HK2 group and the si-circ+miR-inhibitor group.Conclusion Knockdown of circ_UBE2C significantly suppresses the proliferation and glycolysis of lung cancer cells via targeting up-regulation of miR-107 and then exerting inhibitory effect on HK2 expression.

ObjectiveQuorum-sensing (QS) and small regulatory RNA (sRNA) play key regulatory roles in many signaling cascades of Pseudomonas aeruginosa. To investigate whether sRNA is involved in P. aeruginosa QS system, screening QS system-related sRNA, and to construct sRNA overexpression and deletion strains of Pseudomonas aeruginosa for further study of sRNA function.MethodsSRNA associated with the QS system was screened by qPCR and RNA-sequencing (RNA-seq). The target gene were amplified by PCR and inserted into the overexpression vector pROp200 or the homologous recombination vector pGSM-MR, respectively. The connection reaction solution of pROp200-sRNA and pGSM-ΔsRNA was transformed into Escherichia coli DH5a and SM10lp, respectively. The recombinant vectors were identified by PCR. The pROp200-sRNA was transformed into PAO1 by heat shock method, and the pGSM-ΔsRNA was transferred from SM10lp to PAO1 by conjugation. SRNA overexpression and deletion strains were identified by PCR, DNA sequencing and qPCR, the determination of the growth curves and the pyocyanin levels of strains.ResultsFive QS -associated sRNA P26, P5316.1, P30, P34 and AmiL were successfully screened by RNA-seq and qPCR. PCR, DNA sequencing and qPCR showed that sRNA of AmiL, P30 and P34 overexpression and knockout were successful. Compared with wild-type strain, sRNA overexpression and knockout had no significant effect on bacterial growth curve. It were notably that overexpression of AmiL and P30 inhibited and increase the production of pyocyanin, respectively (P<0.01), while deficiency of AmiL and P30 in the genome resulted in significantly increase and decrease of pyocyanin, respectively (P<0.01). Overexpression and deletion of P34 had no significant effect on pyocyanin synthesis (P>0.05).ConclusionThe sRNA overexpression and deletion strains have been successfully constructed and can be used to study the regulatory relationship between sRNA and QS systems, and to further functional study.

【Objective】 To investigate the temperament factor scores and typing characteristics in infants with early eczema, aiming to provide evidence for early intervention in infant eczema. 【Methods】 It was a retrospective and 1: 2 matched case-control study. Using the domestic standardized Early Infancy Temperament Questionnaire(EITQ), we evaluated the temperament factor scores and temperament types of 56 one-month-old eczema infants and 112 healthy infants and then compared the results. 【Results】 The distribution of temperament types is featured with significantly higher proportion of the male infants with D type and I-D type but significantly lower proportion of the male infants with E type and I-E type in the eczema group compared with those in the control group(all P<0.001). Univariate logistic regression analysis of temperament dimension demonstrated that activity, rhythmicity, adaptability and intensity were the influencing factors of eczema (all P<0.05). Multivariate logistic regression analysis(backward stepwise) of temperament dimension showed that adaptability and intensity were the independent influencing factors, and infants in eczema group had strong adaptability and weak intensity. 【Conclusion】 Infants with early eczema have strong adaptability and weak intensity, we should provide early intervention based on their temperament characteristics.

BACKGROUND: The comparative outcomes of subcutaneous implantable cardioverter-defibrillator (S-ICD) and transvenous ICD (T-ICD) have not been well studied. The aim of this study was to evaluate the safety and efficacy of currently available S-ICD and T-ICD. METHODS: The study included 86 patients who received an S-ICD and 1:1 matched to those who received single-chamber T-ICD by gender, age, diagnosis, left ventricular ejection fraction (LVEF), and implant year. The clinical outcomes and implant complications were compared between the two groups. RESULTS: The mean age of the 172 patients was 45 years, and 129 (75%) were male. The most common cardiac condition was hypertrophic cardiomyopathy (HCM, 37.8%). The mean LVEF was 50%. At a mean follow-up of 23 months, the appropriate and inappropriate ICD therapy rate were 1.2% vs. 4.7% (χ = 1.854, P = 0.368) and 9.3% vs. 3.5% (χ = 2.428, P = 0.211) in S-ICD and T-ICD groups respectively. There were no significant differences in device-related major and minor complications between the two groups (7.0% vs. 3.5%, χ = 1.055, P = 0.496). The S-ICD group had higher T-wave oversensing than T-ICD group (9.3% vs. 0%, χ = 8.390, P = 0.007). Sixty-five patients had HCM (32 in S-ICD and 33 in T-ICD). The incidence of major complications was not significantly different between the two groups. CONCLUSIONS The efficacy of an S-ICD is comparable to that of T-ICD, especially in a dominantly HCM patient population. The S-ICD is associated with fewer major complications demanding reoperation.

Objective To investigate the effect of 3-oxo-C12-HSL on autophagy in mouse alveolar macrophages MH-S cells. Methods MH-S cells were treated with culture supernatants of the mutant and wild type Pseudomonas aeruginosa(PA) strains of LasI gene(3-oxo-C12-HSL synthetic gene) and chemically synthesized 3-oxo-C12-HSL signaling molecules. GFP puncta was observed by laser confocal fluorescence microscopy and the ratio of LC3Ⅱ/LC3Ⅰ was detected by Western blot to detect the formation of autophagic.Autophagic flux was also detected by mo-nitoring the degradation of p62 and the change of chloroquine to LC3Ⅱ/LC3Ⅰratio. Results The supernatant of the culture medium of the wild type PA strain increased the GFP puncta of the MH-S cells(P<0.05) and the ra-tio of LC3Ⅱ/LC3Ⅰ(P<0.01),The mutant PA strain of LasI gene could not cause the above changes related to autophagy. The chemically synthesized 3-oxo-C12-HSL signal molecules could increase the number of autophagic bodies and the expression of LC3Ⅱ (P<0.01). Autophagic substrate p62 was degraded by 3-oxo-C12-HSL. Chloroquine, a lysosomal inhibitor, enhanced LC3Ⅱaccumulation caused by 3-oxo-C12-HSL (P<0.05,P<0.01).Conclusions 3-oxo-C12-HSL increases the level of autophagy in MH-S cells.

Most skin damage caused by ultraviolet B (UVB) radiation is owing to the generation of reactive oxygen species. Phytochemicals can act as antioxidants against UVB-induced oxidative stress. This study investigated the protective effects of the flavone galangin against UVB-induced oxidative damage in human keratinocytes. Galangin efficiently scavenged free radicals and reduced UVB-induced damage to cellular macromolecules, such as DNA, lipids, and proteins. Furthermore, galangin rescued cells undergoing apoptosis induced by UVB radiation via recovering mitochondrial polarization and down-regulating apoptotic proteins. These results showed that galangin protects human keratinocytes against UVB radiation-induced cellular damage and apoptosis via its antioxidant effects.

Fucodiphlorethol G (6'-[2,4-dihydroxy-6-(2,4,6-trihydroxyphenoxy)phenoxy]biphenyl-2,2',4,4',6-pentol) is a compound purified from Ecklonia cava, a brown alga that is widely distributed offshore of Jeju Island. This study investigated the protective effects of fucodiphlorethol G against oxidative damage-mediated apoptosis induced by ultraviolet B (UVB) irradiation. Fucodiphlorethol G attenuated the generation of 2, 2-diphenyl-1-picrylhydrazyl radicals and intracellular reactive oxygen species in response to UVB irradiation. Fucodiphlorethol G suppressed the inhibition of human keratinocyte growth by UVB irradiation. Additionally, the wavelength of light absorbed by fucodiphlorethol G was close to the UVB spectrum. Fucodiphlorethol G reduced UVB radiation-induced 8-isoprostane generation and DNA fragmentation in human keratinocytes. Moreover, fucodiphlorethol G reduced UVB radiation-induced loss of mitochondrial membrane potential, generation of apoptotic cells, and active caspase-9 expression. Taken together, fucodiphlorethol G protected human keratinocytes against UVB radiation-induced cell damage and apoptosis by absorbing UVB radiation and scavenging reactive oxygen species.
