Abstract Ring finger protein 183(RNF183) is an E3 ubiquitin ligase that catalyzes the covalent attachment of ubiquitin molecules to substrate proteins. RNF183 is expressed in tissues such as kidney and testis, and it is mainly localized to the endoplasmic reticulum, Golgi apparatus, and lysosomes in cells. As one of the components of the endoplasmic reticulum membrane, it participates in the endoplasmic reticulum stress-responsive pathway that affects cellular and protein ubiquitination. In recent years, the study of E3 ubiquitin ligase member-RNF183 with various diseases such as colorectal cancer, endometrial cancer and bladder cancer has gradually increased. In this review, the role of RNF183 in colorectal cancer, inflammatory bowel disease and other diseases, as well as biological functions such as endoplasmic reticulum stress are summarized, aiming to provide reference ideas for the study of related diseases.

ObjectiveTo investigate the therapeutic effects and difference in the effects of Arisaematis Rhizoma （AR） before and after processing （i.e.， Arisaematis Rhizoma Preparatum， ARP） with Zingiberis Rhizoma Recens-Alumen on allergic asthma in rats and to provide a basis for the theory of processing improving the efficacy. MethodA rat model of allergic asthma was established in 70 SD rats by intraperitoneal injection of ovalbumin （OVA）-aluminum hydroxide. The rats were administrated with the aqueous extracts of AR （1.2， 0.3 g∙kg^-1） and ARP （1.2， 0.3 g∙kg^-1） aqueous extracts by gavage， and montelukast sodium （0.001 g∙kg^-1） was used as the positive drug. The T helper cell type 1/type 2 （Th1/Th2） ratio in the serum and bronchoalveolar lavage fluid （BALF） and percentages of inflammatory cells in BALF were determined. Polymerase chain reaction （PCR） was employed to determine the mRNA level of mucin 5AC （MUC5AC） in the lung tissue. The pathological changes in the lung tissue were observed by hematoxylin-eosin （HE） staining and PAS staining. Immunohistochemical assay was employed to measure the expression of c-Jun amino-terminal kinase （JNK）， extracellular signal regulated protein kinase （ERK）， and p38 mitogen-activated protein kinase （p38 MAPK） in rat lung tissue. Western blot was employed to determine the protein levels of ERK， p-ERK， JNK， p-JNK， p38， p-p38 in the lung tissue. The effects of AR and ARP were compared based on overall desirability. ResultCompared with the blank group， the levels of interleukin-12 （IL-12） and γ interferon （IFN-γ） in serum and BALF of rats in the model group were significantly lower （P<0.05， P<0.01）， and the levels of interleukin-4 （IL-4）， interleukin-5 （IL-5） and interleukin-13 （IL-13） were significantly higher （P<0.05， P<0.01）. Compared with the model group， the serum and BALF contents of IL-12 and IFN-γ in rats in the montelukast sodium group， high-dose AR group and high-dose ARP group were significantly higher （P<0.05， P<0.01）， and the contents of IL-4， IL-5 and IL-13 were significantly lower （P<0.05， P<0.01）， and the serum contents of IFN-γ in rats in the low-dose AR group and low-dose ARP group were in BALF was significantly higher （P<0.05） and IL-4 and IL-13 were significantly lower （P<0.05， P<0.01）， the percentages of macrophages， lymphocytes， neutrophils， and eosinophils were reduced in BALF， and the expression of JNK/ERK/p38 MAPK signaling pathway and MUC5AC protein was inhibited in lung tissues. Overall assessment of the normalized analysis revealed that the ARP group was slightly more potent than the AR group after administration of the same dose. ConclusionAR and ARP can effectively treat allergic asthma by inhibiting JNK/ERK/p38 MAPK signaling pathway， and the effect is better after concoction， which can provide data support for its "concoction efficiency".

OBJECTIVE To explore the correlation between changes in intestinal toxicity and changes in component composition of the Mongolian medicine Euphorbiae pekinensis Radix(EPR)before and after processing with milk.METHODS Mice were given 95%ethanol extract of raw EPR,milk-processed EPR and water-processed EPR by gavage.The purgative effect and intestinal inflam-matory toxicity changes of EPR before and after milk processing were investigated using the fecal water content and the levels of inflam-matory factors TNF-α and IL-1β in each intestinal segment of mice as indicators;LC-MS/MS was used to analyze the composition changes of the 95%alcohol extract of EPR before and after milk processing.RESULTS Compared with the blank group,the raw and water processed products of EPR could significantly increase the water content of mouse feces and the levels of TNF-α and IL-1β in each intestinal segment(P＜0.05);compared with the raw product group,all indicators in the milk processing group were significantly reduced(P＜0.05),while there was no significant difference in the water processing group,indicating that water processing cannot at-tenuate toxicity,and the auxiliary material milk is the key auxiliary material to reduce the toxicity of EPR.Mass spectrometry analysis results showed that a total of 50 components were identified in EPR,including 38 terpenoid components,6 phenolic acid components,and 6 other components.The content of each component decreased to varying degrees after milk processing.Principal component analy-sis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)were performed on the mass spectrum data of raw ma-terials and products,and it was found that the components of raw materials and products can be obviously clustered into 2 categories.13 differential components of raw materials and products were screened through t test,and 11 of which were terpene compo-nents,indicating that the composition of terpene components changed significantly after milk processing.17 components derived from EPR were detected in the residual liquid of milk excipients after processing,of which 16 were terpenoids,indicating that the terpenoid components of EPR were transferred to the excipient milk during the soaking and processing processes.CONCLUSION The toxicity of EPR is reduced and the purgative effect is alleviated after milk processing.The attenuation mechanism may be that during the milk soaking and processing processes,terpenoid components are transferred to the milk,and the content of toxic components in the decoc-tion pieces is reduced,thereby reducing the toxicity.

OBJECTIVE To improve the quality evaluation method of Platycodonis Radix, to study the differences in the quality of three-years-old Platycodonis Radix under different harvesting periods, and to determine the optimal harvesting period of Platycodonis Radix. METHODS The leachate, ash, moisture, refractive index and the content of six saponins were used as the quality evaluation indexes. The differences between the herbs of Platycodonis Radix at different harvesting periods were characterized with the help of mathematical and statistical methods. And link the entropy weight method, gray correlation analysis and TOPSIS method were combined to obtain the statistical analysis of the relevant indexes and the quality ranking information of the herbs in different harvesting periods. RESULTS There were significant differences between the quality evaluation indexes of three-years-old Platycodonis Radix at different harvesting periods. The added multi-indicator testing had improved the quality evaluation system of Platycodonis Radix and enhanced the "Drug properties-Effectiveness" linkage of the herbs. And the results of the comprehensive quality evaluation model showed that the herbs harvested around October 21 (Frost’s Descent) were ranked best in terms of comprehensive index. CONCLUSION In order to ensure the quality of Platycodonis Radix, the best harvesting period for three-years-old Platycodonis Radix is determined around the "Frost’s Descent" season, taking into account the characteristics of the herbs' appearance and the material basis of herbs.

Objective To explore the relationships between headache and pulmonary function,chronic lung disease(CLD)in middle-aged and elderly people in China.Methods This cross-sectional study collected data from participants aged 45 and above in the 2015 China Health and Retirement Longitudinal Study(CHARLS).Headache was diagnosed based on self-report,and CLD and asthma were defined by self-reported doctor diagnoses or a combination of health assessments and medication use.Peak expiratory flow(PEF)was used as an indicator of pulmonary function.Multivariable logistic regression model was used to analyze the correlations between PEF,asthma,CLD,and headache.Relationship between PEF and headache was analyzed by restricted cubic spline(RCS)analysis and subgroup analysis.Results Among 12 661 middle-aged and elderly participants,the prevalence of headache was 14.42%(1 826/12 661),with a prevalence of 9.07%(558/6 151)in males and 19.48%(1 268/6 510)in females.After full adjustment for covariates,each 1 L/s increase in PEF was associated with a 7%reduction in the risk of headache(odds ratio[OR]=0.93,95%confidence interval[CI]0.90-0.96,P＜0.001).Categorizing PEF into quartiles(Q1-Q4),as the increase of PEF,the risk of headache significantly decreased(ORs for Q2,Q3,and Q4 were 0.92,0.82,and 0.72,respectively,Ptrend＜0.001).Additionally,asthma(OR=1.78,95%CI 1.43-2.20,P＜0.001)and CLD(OR=2.21,95%CI 1.92-2.53,P＜0.001)were positively associated with the risk of headache.RCS analysis indicated a negative linear correlation between PEF and the risk of headache(Poverall＜0.001,Pnon-linear=0.57).Subgroup analysis revealed that a history of hypertension had a significant impact on the negative association between PEF and headache(Pinteraction＜0.001).Conclusion There is a significant negative correlation between PEF and headache among middle-aged and elderly people in China,while asthma and CLD are positively associated with headache.Improving lung function in middle-aged and elderly populations may be an effective strategy for preventing or alleviating headache.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective:To investigate the clinical and pathological features of congenital hepatic fibrosis (CHF).Methods:The clinical and pathological findings of 20 patients diagnosed with CHF from 2017 to 2023 were retrospectively analyzed.Results:Among the 20 patients, 8 were males and 12 were females with a median age of 21.5 years. Mostly patients were admitted to the hospital with cirrhosis, portal hypertension and upper gastrointestinal bleeding. Pathological features were diffuse fibrosis in the portal area, formation of fibrous septa of varying width, segmentation of the liver parenchyma, with hyperplasia of small bile ducts. Among them, 1 case (5%) was complicated with Caroli's disease, and 1 case (5%) was HNF1α hepatocellular adenoma. IHC GS showed that was positively expressed in acinar region 3 in 75% cases.Conclusion:CHF is mainly manifested by portal hypertension and its complications. Histopathology is the gold standard for diagnosis. The possibility of CHF should be considered first in children and adolescents with portal hypertension but no history of hepatitis, and complicated kidney disease. The positive pattern of acinus-3 region of GS in IHC is helpful for the diagnosis of CHF.

Purpose: The aim of our study was to investigate the value of baseline and preoperative neutrophil-to-lymphocyte ratio (NLR) in predicting the pathological response and disease-free survival (DFS) of neoadjuvant chemotherapy alone or combined with programmed cell death-1 (PD-1) checkpoint inhibitors in patients with resectable non‒small cell lung cancer (NSCLC). Materials and Methods: Resectable NSCLC patients who underwent neoadjuvant chemotherapy alone or combined with PD-1 checkpoint inhibitors between January 2018 and January 2020 were included. Peripheral venous blood samples of the patients were collected within 3 days prior to the first neoadjuvant treatment and within 3 days prior to surgery. Results: A total of 79 patients in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group and 89 patients in neoadjuvant chemotherapy alone group were included. Thirty-five point four percent of the patients achieved pathological complete response (pCR) in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group, whereas only 9.0% reached pCR in the group of neoadjuvant chemotherapy. High NLR level were correlated with poor pathological response and DFS in neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors group. Multivariate analysis revealed that baseline NLR could independently predict pathological response and DFS in the neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group. Conclusion High NLR level were correlated with poor pathological response and shorter DFS in patients with NSCLC undergoing neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors. Meanwhile, baseline NLR could independently predict response to pathological response and DFS, revealing its potential as a screening tool in NSCLC patients who received neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors.

Objective:To observe the clinical efficacy of angiotensin-receptor neprilysin inhibitors (ARNI) in the treatment of maintenance hemodialysis (MHD) with heart failure.Methods:The clinical data of heart failure patients who accepted MHD in Central China Fuwai Hospital were retrospectively collected. All patients accepted regular treatments of heart failure, and then the treatment group was treated with ARNI, while the control group was treated with valsartan. The treatment course was 6 months. The cardiac parameters: left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), pulmonary artery pressure, right ventricular end-diastolic dimension (RVED), right atrial end-diastolic dimension (RAED), N-terminal pro-B-type natriuretic peptide (NT-pro BNP), and serum potassium were collected and compared between the two groups. Multivariate ordered logistic regression analysis was adopted to analyze the influencing factors of treatment effect.Results:A total of 60 MHD patients with heart failure were enrolled with age of (53.92±11.88) years old, 37 males (61.7%), dialysis age of (27.83±12.92) months, and blood pressure of (154.22±15.27) mmHg/(85.43±12.31) mmHg. (1) There was no significant difference of the clinical data and cardiac parameters between the treatment group ( n=30) and the control group ( n=30) before treatment (all P>0.05); (2) After treatment of 6 months, the total effective rate [28/30(93.3%)] in the treatment group was significantly higher than that in the control group [20/30(66.7%)] and the rehospitalization rate [2/30(6.7%)] in the treatment group was significantly lower than that in the control group [10/30(33.3%)] (both P<0.05); (3) After treatment of 6 months, LVEF, LVEDD, LVESD, pulmonary artery pressure, RVED, RAED, NT-pro BNP, and blood pressure were all improved significantly compared with the baseline in both groups (all P<0.05) and there was no significant difference of serum potassium and body weight before and after treatment in the two groups (all P>0.05); (4) After treatment of 6 months, LVEF in the treatment group was higher than that in the control group and LVEDD, LVESD, pulmonary artery pressure, NT-pro BNP, and blood pressure in the treatment group were lower than those in the control group (all P<0.05). There was no significant difference of RVED, RAED, serum potassium and body weight between the two groups after treatment (all P>0.05); (5)The difference values before and after treatment of LVEF, LVEDD, LVESD, NT-pro BNP, body weight, systolic blood pressure, and diastolic blood pressure were different between the two groups (all P<0.05); (6)Therapy method ( β=-1.863, 95% CI -2.948-0.777, P=0.001) and residual urine ( β=-1.686, 95% CI -3.079- -0.293, P=0.018) were independent influencing factors of treatment effect (the treatment effect of ARNI was better than that of valsartan; the treatment effect of patients with normal urine volume was better than that of patients with oliguria and anuria). Conclusions:ARNI can effectively improve cardiac function in MHD patients with heart failure, inhibit ventricular remodeling, and improve disease prognosis.

Objective: To investigate the current prevalence of latent tuberculosis infection (LTBI) among residents living in Nanchuan District, Chongqing Municipality, so as to provide the evidence for formulating LTBI control measures. Methods: The residents living in one street and one township from Nanchuan District were randomly selected using the multistage cluster sampling method during the period between January and April, 2020, and their demographic information, smoking history, history of alcohol consumption, history of contacts with tuberculosis patients and Bacillus Calmette-Guérin ( BCG ) vaccination scars were collected. The infection of Mycobacterium tuberculosis was detected using interferon gamma release assay ( IGRA ), and a positive IGRA test and exclusion of active tuberculosis was defined as LTBI. The prevalence of LTBI was descriptively analyzed among the study subjects. Results: Totally 1 000 residents were recruited, including 381 males and 619 females, with a male to female ratio of 0.62∶1. The mean age was ( 45.87±18.40 ) years. Among all participants, there were 222 smokers ( 22.20% ), 247 subjects consuming alcohol (24.70%), 62 subjects with a history of contacts with tuberculosis patients ( 6.20% ) and 904 subjects with BCG scars ( 90.40% ). A total of 198 residents were diagnosed with LTBI (19.80% prevalence), and a higher prevalence rate of LTBI was seen in men than in women ( 23.36% vs. 17.61%; χ2=4.911, P=0.027 ). The prevalence of LTBI was significantly higher in married/divorced/widowed residents than in unmarried residents ( 24.22% vs. 2.01%; χ2=49.514, P<0.001 ), and significantly greater prevalence was found in smokers than in non-smokers ( 27.93% vs. 17.48%; χ2=11.871, P=0.001 ). The prevalence of LTBI appeared a tendency towards a rise with age ( χ2trend=59.100, P<0.001 ) and body mass index ( χ2trend=9.479, P=0.002 ). Conclusions The prevalence of LTBI is high among residents living in Nanchuan District, notably among elder, male smokers with high body mass index. Risk monitoring and timely interventions are required.
