Objective To investigate the relationship between CT lung volume parameters(CT-LVP)and pulmonary function grade in patients with idiopathic pulmonary fibrosis(IPF)and its prediction of acute exacerbation.Methods A total of 204 patients with IPF were selected and divided into mild group(67 cases),moderate group(72 cases)and severe group(65 cases)according to the semi-quantitative scoring method of high-resolution computed tomography(HRCT).The correlation between CT-LVP and pul-monary function parameters(PFP)were analyzed.The predictive value of CT-LVP for acute exacerbation in severe IPF was ana-lyzed.Results The whole lung volume(WLV),normal lung volume(NLV)and normal lung volume percentage(NLV%)in severe group were lower than those in mild and moderate groups,whereas interstitial lung disease volume(ILDV)and interstitial lung disease volume percentage(ILDV%)were higher than those in mild and moderate groups,with statistical significance(P<0.05).WLV,NLV,ILDV,NLV%,ILDV%showed strong correlations with forced expiratory volume in 1 second percentage(FEV1%),forced expiratory volume in 1 second to forced vital capacity ratio(FEV1/FVC),diffusing capacity of the lung for carbon monoxide percent-age(DLCO%),and residual volume to total lung capacity ratio(RV/TLC).Receiver operating characteristic(ROC)curve analysis showed that the combination of WLV,NLV,ILDV,NLV%and ILDV%had higher accuracy in predicting acute exacerbation,area under the curve(AUC)>0.75(P<0.05).Conclusion CT-LVP is closely related to PFP,and the accuracy of CT-LVP combination in predicting acute exacerbation is high,which provides a theoretical basis for preventing acute exacerbation of IPF.

Epidermal growth factor receptor inhibitor (EGFRI) -related paronychia is a condition clearly related to EGFRI therapy, characterized by periungual erythema, edema, purulent exudates, periungual or subungual granulomatous lesions, and sometimes accompanied by thinning, fragility or even splitting and seperation of nail plates. Inhibition of epidermal function, inflammation and secondary infections, as well as angiogenesis are the core processes in the occurrence and development of EGFRI-related paronychia. This review summarizes epidemiology, pathogenesis, clinical manifestations, prevention and treatment of EGFRI-related paronychia.

Objective To investigate the expression changes of serum circRNA membrane bound O-acyltransferase 2(circRNA MBOAT2)and circRNA recombinant actinin 4(circRNA ACTN4)in patients with cholangiocarcinoma and their relationship with prognosis.Methods 96 patients with cholangiocarcinoma treated at the First Hospital of Handan City from January 2020 to January 2022 in Department of Hepatobiliary Surgery were regarded as as the cholangiocarcinoma group.Additionally,85 patients with intraductal stones and 90 healthy volunteers were collected as the stone group and control group,respectively.Quantitative real-time reverse transcription PCR(qRT-PCR)was applied to detect the expression levels of circRNA MBOAT2 and circRNA ACTN4.χ2 test was applied to analyze the relationship between circRNA MBOAT2 and circRNA ACTN4 and clinical pathological features.Pearson was applied to analyze the correlation between circRNA MBOAT2 and circRNA ACTN4 in patients with cholangiocarcinoma.ROC was applied to analyze the diagnostic value of circRNA MBOAT2 and circRNA ACTN4 in the occurrence of cholangiocarcinoma.COX was applied to analyze the influencing factors of poor prognosis in patients with cholangiocarcinoma.Kaplan-Meier method was applied for survival analysis.Results circRNA MBOAT2(1.24±0.38)and circRNA ACTN4(1.27±0.42)in cholangiocarcinoma group were higher than those in stone group(1.02±0.31,1.05±0.34)and control group(0.83±0.24,0.78±0.21),and the stone group was higher than that in control group,with statistically significance(t=5.016～14.025,all P<0.05).There was a positive correlation between circRNA MBOAT2 and circRNA ACTN4 in patients with cholangiocarcinoma group(r=0.428,P<0.05).Combined diagnosis of MBOAT2 and ACTN4 was better than single diagnosis of cholangiocarcinoma(Z=4.063,4.004,all P<0.05);circRNA MBOAT2 and circRNA ACTN4 were correlated with clinical staging and lymph node status(t=5.091～5.984,all P<0.05).Positive lymph node status and elevated levels of circRNA MBOAT2 and circRNA ACTN4 were independent risk factors for mortality(HR=1.527,1.582,1.727,all P<0.05).The cumulative survival rate of patients with high expression of circRNA MBOAT2(23.40%vs 46.94%)and circRNA ACTN4(24.00%vs 47.83%)was lower than that of patients with low expression(χ2=5.809,5.946,all P<0.05).Conclusion The serum levels of circRNA MBOAT2 and circRNA ACTN4 increase with the progression of the disease,and the combination of the two has certain value in diagnosing the occurrence of cholangiocarcinoma.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

Nonalcoholic fatty liver disease （NAFLD） is a multisystem disease associated with obesity， insulin resistance， and dyslipidemia and has a complex pathogenesis. Studies have shown that gut microbiota dysbiosis is closely associated with the onset of NAFLD， and traditional Chinese medicine treatment can improve the laboratory markers and clinical symptoms of NAFLD patients by regulating intestinal microbiota and its metabolites. This article elaborates on the association between NAFLD and gut microbiota， the involvement of gut microbiota dysbiosis in the pathogenesis of NAFLD， and the possible mechanism of traditional Chinese medicine treatment in improving NAFLD from the perspective of gut microbiota， in order to provide new ideas for the treatment of NAFLD.

A 69-year-old male patient with cervical discitis received linezolid treatment for two months.The white blood cell count,red blood cell count,hemoglobin,and platelet count of the patient were all below normal ranges.Simultaneously,the blood lactate level increased to 2.6 mmol·L-1,and he experienced blurred vision and worsening olfactory dysfunction.After discontinuing linezolid,treatment with erythropoietin injections and Diyu Shengbai tablets was initiated.The blood parameters gradually returned to normal,as did the lactate level,and the vision and olfactory impairment of the patient were improved.Using Naranjo's assessment scale indicated that the adverse drug reaction was"probably relevant"such as pancytopenia,elevated lactate,visual disturbances,and exacerbated olfactory dysfunction,were likely to be due to linezolid.While severe adverse reactions to linezolid typically manifest in isolation,clinicians and pharmacists should remain vigilant for the simultaneous occurrence of multiple adverse reactions.The onset of adverse reactions is associated with the duration of therapy,dosage,and the patient's baseline health.Monitoring of drug levels and relevant parameters during treatment can help in early detection of such adverse reactions.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.
