Objective To investigate the clinical efficacy of the traditional Chinese medicine(TCM)throat opening and brightening method in treating unilateral vocal cord paralysis(UVCP).Methods Sixty patients with UVCP were prospectively collected and randomly assigned to two groups:the Chinese herbal medicine group(trea-ted with Buyang Huanwu Decoction,n=30)and the throat opening and brightening method group(treated with TCM throat opening and brightening method,n=30).The clinical studies that had utilized injection laryngoplasty for the treatment of UVCP(historical control group).Evaluation indicators included the voice handicap index-10(VHI-10),GRBAS-G,objective acoustic measurements of voice(vocal intensity,F0,shimmer,jitter,HNR),and aerodynamic measurements(maximum phonation time,MPT).Results Before treatment,no significant differences were observed between the two groups in all the evaluation indicators(P＞0.05).Post-treatment,the throat open-ing and brightening method group demonstrated significant improvements in VHI-10,GRBAS-G,shimmer,jitter,HNR,and MPT compared to pre-treatment values(P＜0.01),and these improvements were superior to those in the Chinese herbal medicine group.Pre-treatment VHI-10,GRBAS-G,and shimmer scores in the throat opening and brightening method group were significantly higher than those in the historical literature group(P＜0.01).Af-ter treatment,no significant differences were noted in any assessed parameters between the two groups(P＞0.05).Conclusion The TCM throat opening and brightening method significantly enhances phonatory function and quality of life in patients with UVCP,showing comparable efficacy to injection laryngoplasty.

Objective:To explore the mediating effect of dyadic coping between perceived social support and family cohesion and adaptability and happiness in spouses of patients with post-stroke motor impairments.Methods:From December 2023 to May 2024, a total of 366 spouses of patients with post-stroke motor impairments who received treatment at the First Affiliated Hospital of Zhengzhou University were recruited as study participants. Data were collected using the general information, perceived social support scale, dyadic coping inventory, Chinese version of the family cohesion and adaptability scale(FACESⅡ-CV), and memorial University of Newfoundland scale of happiness. The AMOS 21.0 software was utilized to construct a structural equation model to examine the mediating effect of dyadic coping between perceived social support, family cohesion and adaptability and happiness.Results:The spouses of patients with post-stroke motor impairments reported overall scores for perceived social support (62.80±12.80), dyadic coping (117.07±20.78), family cohesion and adaptability (115.96±19.51), and happiness (22.27±7.29). Family cohesion and adaptability was positively correlated with dyadic coping and perceived social support ( r=0.614, 0.520, both P<0.01).Spousal happiness was positively correlated with dyadic coping and perceived social support ( r=0.296, 0.202, both P<0.01).The spouses recognized that perceived social support had a positive correlation with dyadic coping ( r=0.479, P<0.01).Dyadic coping played a partial mediating effect between perceived social support and family cohesion and adaptability as well as happiness, accounting for 32.41% (0.211/0.651) and 44.39% (0.190/0.428) of the total effect, respectively. Conclusion:Dyadic coping is the mediating variable of family cohesion, adaptability and happiness of spouses of patients with post-stroke motor impairments. Medical staff should try to construct a dyadic coping intervention plan to improve the dyadic coping level of spouses of patients with post-stroke motor impairments, so as to improve their family happiness index.

In the context of global climate change, the impact of ambient temperature change on cardiovascular health has become increasingly significant. Epidemiological studies have shown that both high and low temperature can lead to the occurrence of adverse cardiovascular outcomes. For example, exposure to low temperature and high temperature, and diurnal temperature difference can increase the risk of cardiovascular diseases (CVD) mortality. Exposure to cold and heat, heatwaves and cold spells may induce myocardial infarction. Low temperature, high temperature and variations in temperature can increase the risk of heart failure. There are complex interactions among the effects of temperature and humidity, wind speed, radiation, precipitation and air pollution on adverse cardiovascular outcomes. Valnerable groups such as the elderly, patients with chronic diseases, and outdoor workers are particularly susceptible to temperature-related CVD risks. The mechanisms by which temperature affects adverse cardiovascular outcomes involves hemodynamic changes, autonomic nervous system dysregulation, blood rheology alterations, as well as inflammation and metabolic abnormalities, but many research gaps remain. Future studies should conduct in-depth research on mechanisms, individual differences, climate change impacts, and public health interventions to provide more effective policies and interventions to reduce the burden of CVD.

Hypertriglyceridemia （HTG） is the second leading cause of acute pancreatitis in China and can be caused by primary factors， namely gene mutations， which may lead to recurrent hypertriglyceridemic acute pancreatitis （HTG-AP） and difficulties in effective control of triglyceride. This article reports an adult Chinese male patient who experienced eight attacks of HTG-AP and was found to carry a de novo heterozygous mutation， p.K327N， of the GPD1 gene， which may cause the persistent high level of triglyceride and recurrent attacks of HTG-AP.

Objective Screening for sensitive biomarkers for predicting and analyzing drug-induced renal toxicity,accelerates drug early development.Methods Focuses on epithelial cells of proximal convoluted tubules in human renal cortex(human kidney-2,HK-2)cells as the research object,screening for highly sensitive biomarkers using three nephrotoxic drugs(cisplatin,gentamicin,and aristolochic acid Ⅰ).Results The sensitivity of biomarkers in intracellular fluid is higher than in extracellular fluid,compared to detecting a single biomarker in the intracellular fluid.The combined detection of β2-microglobulin(β2-MG)and neutrophil gelatinase-associated lipocalin(NGAL)improved the accuracy of renal toxicity evaluation.Conclusion Based on the HK-2 cell model,the combined detection of β2-MG and NGAL in intracellular fluid can be used to predict renal toxicity in the drug's early development stage.

Objective To investigate the characteristic volatile organic compounds(VOCs)in exhaled breath and their diagnostic value in mice with early stage radiation injury.Methods The thermal desorption gas chromatography-mass spectrometry(TD-GC/MS)technique was used to analyze VOCs in exhaled breath of irradiated mice by 60Coγ-ray with 800 cGy.The characteristic VOCs in the early stage of radiation injury were identified,and a diagnostic model was established.Results The 30-day survival rate of mice was 4.2%.There were significant differences in characteristic VOCs at 7 hours after radiation injury,and thirty characteristic VOCs related to early-stage radiation injury were identified.The diagnostic value of differential metabolites in mice after irradiation was evaluated via the ROC curve,and the area under the ROC curve(AUC)of a single compound exceeded 0.8.The diagnostic model was constructed by screening 9 potential biomarkers of exhalation through Fisher discriminant analysis,and its sensitivity and specificity were close to 100%.Conclusion Analysis of VOCs in exhaled breath is expected to provide a non-invasive diagnostic method for early screening and diagnosis of radiation injury.

AIM:To investigate the effect of Bushen formulae(BHF)on bone metabolism and its possible mechanism in ovariectomized rats with high salt intake.METHODS:According to the random number table method,80 SPF-grade Sprague-Dawley rats were divided into sham group,ovariectomy(OVX)group,medium-high-salt diet(MSD)group,high-salt diet(HSD)group,BHF group,BHF with normal saline(BHF+NS)group,BHF+MSD group,and BHF+ HSD group,with 10 rats in each group.After modeling,different diets and BHF formula interventions were administered,and the concentrations of sodium chloride added to MSD group and HSD group were 2%(w/w)and 8%(w/w),respective-ly.The dose of BHF was 7.8 g·kg-1·d-1,once a day,and the treatment lasted for 12 weeks.Bone density,bone microar-chitecture,bone parameters,bone metabolism biomarkers,bone histopathological changes,the expression of epithelial sodium channel α(ENaCα),Na-Cl cotransporter(NCC),and voltage-gated chloride channel 3(ClC-3)proteins in bone tissue were detected in each group.RESULTS:Compared with sham group,the rats in OVX group had reduced bone density and destroyed bone microstructure.Compared with OVX group,the bone microstructure in MSD and HSD groups was more significantly damaged,while the levels of bone formation markers,bone glycoprotein(BGP)and type Ⅰ procolla-gen N-terminal peptide(PINP),were significantly increased in HSD group(P<0.05).Moreover,the levels of bone re-sorption markers,such as amino-terminal cross-linked telopeptides of type Ⅰ collagen(NTX),carboxy-terminal cross-linked telopeptides of type Ⅰ collagen(CTX)and tartrate-resistant acid phosphatase(TRACP),were significantly in-creased(P<0.05),indicating that bone metabolism was in high-conversion state.High-salt diet accelerated the structural destruction of bone trabeculae,and Western blot results showed that high-salt diet caused decreases in the protein expres-sion levels of ENaCα and ClC-3 and an increase in the protein expression level of NCC in femoral tissues(P<0.05).After BHF intervention,the expression of relevant ion channels caused by high salt could be regulated to different degrees.CONCLUSION:Bushen formulae could differentially regulate the expression of relevant ion channels ENaCα,ClC-3,and NCC induced by high salt to different degrees,which has certain ameliorative and therapeutic effects on the imbalance of bone metabolism.
