Objective:To sinicize the English version of the rapid eye movement sleep behavior disorder symptom severity scale (RBDSSS) and to evaluate the reliability and validity of the Chinese version of RBDSSS (RBDSSS-C) among Chinese patients with rapid eye movement sleep behavior disorder (RBD).Methods:RBDSSS-C was ultimately formed through translation, back translation and revision according to the Brislin's translation model, including patient version (RBDSSS-PT) and bedpartner version (RBDSSS-BP). A questionnaire survey was conducted among 120 RBD patients to test the reliability and validity of the RBDSSS-C, using Cronbach’s α coefficient, Spearman-Brown coefficient, Spearman correlation analysis, content validity index and factor analysis. The correlation between RBDSSS-C and RBDQ-HK was examined.Results:For the Chinese version of RBDSSS-PT, the Cronbach’s α was 0.795, the split-half reliability was 0.756, and the test-retest reliability was 0.940. Item-level content validity indices (I-CVI) ranged from 0.833 to 1.000, and the scale-level CVI (S-CVI) was 0.937.For the Chinese version of RBDSSS-BP, the Cronbach’s α was 0.712, the split-half reliability was 0.813, and test-retest reliability was 0.950, with both I-CVI and S-CVI at 1.000.The scores of Chinese version of RBDSSS-PT and RBDSSS-BP were both significantly correlated with RBDQ-HK scores ( r=0.638, P<0.001 for RBDSSS-PT; r=0.639, P<0.001 for RBDSSS-BP). Factor analysis confirmed both single-factor structure for RBDSSS-PT and RBDSSS-BP.RBDSSS-PT showed χ2/ df=3.930, CFI=0.954, TLI=0.937, and RMSEA=0.093; RBDSSS-BP showed χ2/ df=8.300, CFI=0.975, TLI=0.966, and RMSEA=0.079. These results indicated adequate model fit. Conclusion:RBDSSS-C has good reliability and validity, and can be used as a reliable and effective tool to evaluate the severity of symptoms in Chinese RBD patients.

Soy is a vital source of plant carbohydrates.However,it poses significant allergenic risks,particularly to young children and animals.Among the various proteins in soy,β-conglycinin,which con-stitutes approximately 30％of total soy carbohydrates,is a primary allergen.Undigested β-conglycinin can lead to intestinal damage by inhibiting cell growth,disrupting the cytoskeleton,and inducing apopto-sis.It can also enter the lymphatic and circulatory systems,triggering allergic reactions.Conventional ELISA methods for detecting β-conglycinin rely on polyclonal or monoclonal antibodies,which are limited by their large molecular weight,difficulty in accessing the protein core,and sensitivity to acidic and bas-ic conditions.To address these limitations,this study aimed to develop nanobodies(Nbs)against β-con-glycinin.Nbs,derived from the variable regions of heavy-chain antibodies found in camelids,have a mo-lecular weight approximately one-tenth that of conventional antibodies.They offer advantages such as small size,stable structure,high specificity,and strong affinity.A female alpacas was immunized five times using β-conglycinin,which showed a heavy chain antibody potency of 1∶16 000 by ELISA.Pe-ripheral blood lymphocytes were subsequently isolated and total RNA was extracted.The variable region of the heavy-chain antibody was amplified via PCR,and recombinant plasmids were constructed and transformed into the E.coli competency strain ER2738.The resulting library contained about 3.5×108 CFU/mL,which increased to 1.15×1012 PFU/mL after phage rescue,with a 100％Nbs gene insertion rate,indicating high diversity.Its Nbs phage output was significantly enriched by four rounds of solid-phase elution with an enrichment rate of 155.9.Four rounds of solid-phase panning yielded 35 positive clones,all of which shared the same amino acid sequence upon sequencing.The selected Nb was ex-pressed in a prokaryotic system,and its binding ability to β-conglycinin was confirmed using Western blotting and ELISA.The results demonstrated excellent specificity and affinity.This research lays the groundwork for developing a rapid and efficient detection method for β-conglycinin using Nbs,potentially enhancing food safety and allergen management.

Objective To develop an ICU patient care difficulty index based on psychosocial factors and to evaluate its reliability and validity,thereby providing a comprehensive tool for assessing the difficulties in ICU patient care.Methods Guided by Guarinoni theory,an index system was developed through systematic literature reviews,semi-structured interviews,two rounds of Delphi expert consultation and the analytic hierarchy process.Based on the drafted system,a questionnaire was formulated.The tests for validity and reliability were conducted on 290 patients selected by convenience sampling.Results The finalised ICU patient care difficulty index system was composed of 5 primary indices(the general condition of the patient,disease condition,nursing condition,social support,and organizational characteristics),13 secondary indices and 27 tertiary indices.The Kendall's coefficient of coordination W values were 0.380 and 0.498,respectively,indicating a statistically significant agreement(both P<0.001).The system demonstrated a robust reliability(Cronbach's α=0.896)and a good internal consistency.Validity was confirmed through a scale level-content validity index(S-CVI)of 0.94 and the item level-content validity indices(I-CVI)ranged from 0.87 to 1.00.Structural validity analysis,based on 8 extracted public factors,showed a cumulative variance contribution rate of 66.34%.Conclusion The ICU patient care difficulty index system shows a high reliability and validity,making it a valuable tool for accurately quantification of the difficulty in ICU patient care.This system provides a scientific basis for allocation of ICU nursing resource and performance distribution.

Aim To explore the effect of astragalosideⅣ(AS-Ⅳ)on lipopolysaccharide(LPS)-induced po-larization and migration of RAW 264.7 macrophages and the underlying mechanism.Methods 1 mg·L-1 LPS was used to construct cell migration model.Scratch assay was utilized to determine cell migration rate.Immunofluorescence staining was utilized to de-tect the expression and location of F4/80,iNOS and Arg-1.CCK-8 assay was used to determine the viabili-ty of RAW 264.7 cells.Griess assay was used to measure NO content.Molecular docking was used to analyze the interaction between AS-Ⅳ and the core tar-gets such as cGAS and STING protein.Western blot was employed to detect the expression of iNOS,Arg-1,cGAS,STING,NF-κB p65 and p-NF-κB p65 protein.Results AS-Ⅳ significantly inhibited the migration and M1 polarization of RAW 264.7 cells induced by LPS.Moreover,AS-Ⅳ could interact with cGAS and STING protein,especially cGAS.Further Western blot assay showed that AS-Ⅳ significantly downregulated the expression of iNOS,cGAS,STING and p-NF-κB p65 protein.Conclusions AS-Ⅳ could promote mac-rophage M1 to M2 polarization,thereby inhibited mac-rophage migration through restraining the cGAS/STING/NF-κB signaling pathway,which provides a new therapeutic target for AS-Ⅳ to improve the early inflammatory response of AS.

Objective To develop a static progressive ankle stretcher for the treatment of functional disorders caused by scar contracture of the Achilles tendon after burn,and to evaluate its application effect.Methods The static progressive ankle stretcher was composed of a plantar support section and a calf support section,which was mainly made of a 3.2 mm-thick medical low-temperature thermoplastic plate,a commercially available 1 mm-diameter steel wire rope,grooved wheels,ice fishing reels with a diameter of about 50 mm,curved folding hinges and a locking threader with a hole diameter of about 1.5 mm.Totally 49 patients with scar contracture after deep Ⅱ to Ⅲ-degree burns of the Achilles tendon admitted to some hospital from March 2021 to January 2023 were prospectively selected and divided into a conventional rehabilitation group(25 cases)and a combined rehabilitation group(24 cases)using a randomized numerical table method.The patients in the conventional rehabilitation group underwent routine scar care such as anti-scarring medication application at home,scar massage,resistance training,joint loosening training in the hospital and compression therapy with the customized compression stockings/pants at the rest of the time,the patients in the combined rehabilitation group were treated with the static progressive ankle stretcher besides the measures taken for the conventional group.The two groups were compared in terms of scarring,ankle function and active dorsiflexion mobility of the ankle joint before and 12 weeks after the treatment,balance and walking ability 4 weeks and 12 weeks after the treatment,adverse events during the treatment and patient satisfaction 12 weeks after the treatment.SPSS 23.0 statistical software was used for data analysis.Results In terms of scarring condition,ankle function and active dorsiflexion mobility of the ankle joint all the patients were improved 12 weeks after the treatment,and the ones in the combined rehabilitation group behaved better than the ones in the conventional group,with the differences being statistically significant(P<0.05).The balance and walking ability 12 weeks after the treatment was better than that 4 weeks after the treatment in the two groups,and the combined rehabilitation group gained advantages over the conventional group in balance and walking ability,with the difference being statistically significant(P<0.05).During the treatment no adverse events due to the static progressive ankle stretcher were found,such as muscle tissue strain,scarred skin rupture,instrument friction and pressure injury.The combined rehabilitation group had higher patient satisfaction than the conventional group 12 weeks after the treatment,with the differences being statistically significant(P<0.05).Conclusion The static progressive ankle stretcher combined with the conventional rehabilitation treatment contributes to improving contracture scar conditions and joint mobility at the Achilles tendon area of the post-burn patients,which helps accelerate the recovery of ankle function after burns and enhance the balance and walking ability of the patients.[Chinese Medical Equipment Journal,2025,46(10):54-59]

Objective To investigate the effects of Gandou Fumu Decoction on liver fibrosis,iron metabolism,and ferroptosis in patients with hepatolenticular degeneration(Wilson disease,WD).Methods Seventy-eight hospitalized patients with WD characterized by kidney and liver deficiency,with phlegm and blood stasis,from the Department of Neurology,the First Affiliated Hospital of Anhui University of Chinese Medicine,were randomly assigned to two groups using a random number table method.The control group(n=39)received sodium dimercaptosulfonate in combination with a low-copper and high-protein diet.The observation group(n=39)received the same treatment as the control group,with the addition of Gandou Fumu Decoction(one dose per day,taken twice daily,in the morning and evening).Both groups underwent six treatment cycles,each lasting eight days.Ultrasonographic parameters,including portal vein main trunk diameter(PVMD),portal vein velocity(PVV),shear wave velocity(SWV),liver stiffness measurement(LSM),serum liver fibrosis markers(hyaluronic acid[HA],laminin[LN],procollagen typeⅢN-terminal peptide[PⅢNP],collagen type Ⅳ[CⅣ],aspartate aminotransferase to platelet ratio index[APRI],fibrosis-4 index[FIB-4]),and iron metabolism indicators(serum iron[SI],ferritin[FT])were compared before and after treatment.The relationship between baseline iron metabolism markers and ultrasonographic parameters,as well as serum liver fibrosis markers,was analyzed.Clinical efficacy,traditional Chinese medicine(TCM)syndrome scores,and adverse reactions were also compared between the groups.Additionally,bioinformatics analysis was performed to identify potential targets of Gandou Fumu Decoction for WD treatment.Peripheral blood mononuclear cells were collected from a normal group of 20 healthy individuals,as well as from both the control and observation groups before and after treatment.Real time fluorogenic quantitative PCR was performed to validate the expression changes of these targets across the groups.Results Compared with pre-treatment values,no significant changes were observed in PVMD levels in either group after treatment.No significant change in PVV was observed in the control group,whereas a significant decrease was noted in the observation group(P＜0.01).SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,FIB-4,and FT levels were significantly reduced compared to pre-treatment levels(P＜0.05,P＜0.01),whereas SI remained unchanged.Compared with the control group,the observation group had no significant difference in PVMD but had significantly lower PVV,SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,FIB-4,and FT levels(P＜0.05,P＜0.01),whereas SI remained unchanged.The total effective rate of treatment in the observation group was significantly higher than that in the control group(P＜0.05).Both groups showed a significant reduction in TCM syndrome scores after treatment(P＜0.01),with a significantly greater reduction observed in the observation group(P＜0.01).No significant adverse reactions were reported during treatment.Before treatment,there was no significant correlation between the SI of both groups and PVMD,PVV,SWV,LSM,HA,LN,PⅢNP,CⅣ,APRI,and FIB-4.In the observation group,FT showed a positive correlation with SWV,LSM,LN,PⅢNP,CⅣ,APRI,and FIB-4(P＜0.05,P＜0.01),while in the control group,FT showed a positive correlation with HA,LN,PⅢNP,CⅣ,APRI,and FIB-4(P＜0.01).After treatment,in the control group,SI showed a positive correlation with APRI and FIB-4(P＜0.05,P＜0.01),but there was no significant correlation between SI in the observation group and FT in both groups with the above-mentioned indicators.Bioinformatics analysis identified four potential targets of Gandou Fumu Decoction for treating WD,namely heme oxygenase 1(HMOX1),peroxisome proliferator-activated receptor alpha(PPARα),small heat shock protein B1(HSPB1),and mitogen-activated protein kinase 3(MAPK3).Compared to the normal group,both the control and observation groups had significantly lower PPARαand HSPB1 expression and significantly higher HMOX1 and MAPK3 expression before treatment(P＜0.01).Compared to before treatment within the same group,both groups showed significantly increased PPARα and HSPB1 expression and significantly decreased HMOX1 and MAPK3 expression after treatment(P＜0.05,P＜0.01).After treatment,the observation group had significantly higher PPARα and HSPB1 expression and lower HMOX1 and MAPK3 expression than the control group(P＜0.05,P＜0.01).Conclusion Gandou Fumu Decoction demonstrates remarkable advantages in improving clinical efficacy,Chinese medicine syndrome scores,iron metabolism,liver fibrosis progression,ultrasound imaging parameters,and ferroptosis-related biomarkers expression in patients with WD,with a favorable safety profile.
