Objective To analyze the evaluation value of the standard deviation of erythrocyte volume distribution width(RDW-SD),erythrocyte volume distribution width standard deviation and platelet ratio(RPR)and erythrocyte volume distribution width standard deviation and lymphocyte ratio(RLR)in the de-compensation stage of cirrhosis in primary biliary cholangitis(PBC).Methods The blood routine indexes of 68 patients with PBC admitted and treated in this hospital from January 2019 to June 2021 were retrospective-ly analyzed and divided into the compensation stage(n=36)and decompensation stage(n=32)according to the diagnostic standard.2 mL venous blood was extracted from the patient on an empty stomach in the early morning.The red blood cell(RBC),mean corpuscular volume(MCV),hemoglobin(Hb),hematocrit(HCT),mean erythrocyte hemoglobin content(MCHC),RDW-SD,white blood cell(WBC),neutrophil absolute value(N#),lymphocyte absolute value(L#),platelet count(PLT),mean platelet volume(MPV),platelet volume distribution width(PDW),etc.were detected.The platelet to lymphocyte ratio(PLR),RPR and RLR were calculated.The influencing factors of decompensation stage of PBC cirrhosis were analyzed by binary logistic regression,and the receiver operating characteristic(ROC)curve was used to analyze the diagnostic values of different indicators in the decompensation stage of PBC cirrhosis.Results There were statistically significant differences in age,RBC,Hb,HCT,RDW-SD,L #,PLT,RPR and RLR between the compensation group and decompensation group in PBC cirrhosis(P＜0.05).The binary logistic regression analysis showed that the age[odds ratios(OR)=1.087,95％confidence intervals(CI):1.015-1.165,P＜0.05],RDW-SD(OR=1.144,95％CI:1.030-1.270,P＜0.05)and RLR(OR=1.041,95％CI:1.007-1.075,P＜0.05)were the independent risk factors for progressing to the decompensation stage in the patients with PBC cirrhosis com-pensation stage.The ROC curve analysis showed that the areas under ROC curve(AUC)of RDW-SD,RPR and RLR for the diagnosis alone of decompensation stage of PBC cirrhosis were 0.726,0.778 and 0.798,re-spectively,and the differences were not statistically significant(P＞0.05).Conclusion Combined with the age factor,regular monitoring of RDW-SD,RPR and RLR levels has a high predictive value for the develop-ment of PBC cirrhosis compensation stage to decompensation stage.

Objective To investigate the effects of comprehensive nutrition management on glycolipid metabolism and pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods A total of 121 pregnant women with GDM at 24-28 weeks gestation who were registered in the obstetrics department of 6 sub-central hospi-tals in China from May 2021 to July 2021 were included in this study and were randomly divided into intervention group(n=74)and control group(n=47).The intervention group received intensive comprehensive nutrition man-agement,including at least 6 outpatient interventions,individualized nutrition management and a half-day standard-ized outpatient education on gestational diabetes mellitus,continuous dynamic blood glucose monitoring and micro-blood glucose monitoring,and routine check of glycated albumin and urine every 4 weeks.Body weight,body com-position and diet and exercise implementation procedures and fetal development as well as complications were recor-ded.The control group received conventional nutritional guidance.The two groups were compared for difference in blood glucose related indicators at 37 weeks of gestation,weight gain before delivery,some lipid metabolism indica-tors,pregnancy outcomes,and oral glucose tolerance test(OGTT)at 42 days postpartum.Results Compared with the control group,the level of prenatal fasting blood glucose(P=0.006),intravenous plasma glucose(P=0.009)and blood ketone(P = 0.044)in the intervention group was significantly reduced.There was no significant difference in weight gain and weight attainment rate between the two groups.The 2-hour postpartum OGTTs of preg-nant women in the intervention group(P=0.006)were significantly lower than those in the control group,and the incidence of preeclampsia and postpartum blood loss were lower than those in the control group but no statistical difference was found.For newborns,the incidence of macrosomia(P=0.042)and planation(P=0.048)in the in-tervention group was slightly lower than that in the control group,and the results were statistically different.Other adverse pregnancy outcomes were not statistically different between the two groups.Conclusions Intensive compre-hensive nutrition management has a positive impact on the control of the blood glucose in pregnant women and im-proves the maternal and neonatal outcomes of women with GDM.

Objective:To explore the anti-inflammatory effect and safety of two non-steroidal anti-inflammatory drugs in the phacoemulsification combined with intraocular lens (IOL) implantation.Methods:A randomized, double-blind, clinical trial was conducted.A total of 90 age-related cataract patients (90 eyes) who were diagnosed in Qingdao Eye Hospital Affiliated to Shandong First Medical University were enrolled from October 2020 to February 2021.The patients were randomized to diclofenac sodium group and bromofenac sodium group by random number table method, with 45 cases (45 eyes) in each group.All patients underwent phacoemulsification combined with IOL implantation, and 0.1% diclofenac sodium eye drops (preservative-free), 4 times a day, and 0.1% pramiphene eye drops, 2 times a day were applied in the perioperative period.The duration of continuous medication treatment and follow-up time were 6 weeks.The subjective symptoms of the patients were scored before and after surgery.The amount of tear fluid secretion was detected by Schirmer I test, and the tear film breakup time was recorded with the Oculus dry eye analyzer.Corneal fluorescein staining was observed under a slit lamp microscope with cobalt blue light.Anterior chamber flash was measured by slit-lamp biomicroscopy.The thickness of central macular area and the presence of macular cystoid edema was measured by optical coherence tomography.Visual acuity, noncontact intraocular pressure (IOP) and the drug safety were examined and evaluated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Qingdao Eye Hospital (No.[2020]60).All patients were informed about the surgery and postoperative medication and signed the informed consent form.Results:All subjects had no intraoperative complications, and completed treatment and follow-up as required.The preoperative, 1-day postoperative, 1-week postoperative, 6-week postoperative subjective symptom scores were (0.47±0.73), (0.56±0.62), (0.33±0.48), and (0.51±0.66) points in the diclofenac group, and (0.47±0.51), (0.75±0.61), (0.64±0.65), and (0.78±0.77) points in the bromfenac group.There were statistically significant differences in the subjective symptom scores at different time points between the two groups ( Fgroup=5.001, P=0.028; Ftime=2.920, P=0.035), and the subjective symptom scores of diclofenac sodium group were significantly lower than those of bromofenac sodium group (all at P<0.05).The preoperative, 1-week postoperative, 6-week postoperative tear secretion volume were (5.87±2.37), (6.07±2.53), and (6.29±0.25) mm in diclofenac sodium group, and (7.36±2.74), (6.29±3.46), and (5.80±2.76) mm in bromofenac sodium group.There was statistically significant difference in the tear secretion volume between the two groups before surgery ( F=6.910, P=0.012), but there was no significant difference on postoperative weeks 1 and 6 ( F=1.121, 0.772; P=0.729, 0.384).The preoperative, 1-week postoperative, 6-week postoperative non-invasive tear break-up time (NIBUT) were (8.00±6.28), (6.68±5.24), and (6.17±5.00) seconds in diclofenac sodium group, and (6.40±5.28), (4.50±2.46), and (5.39±5.39) seconds in bromofenac sodium group.There was no significant difference in NIBUT between the two groups ( Fgroup=3.415, P=0.068).There was significant difference in NIBUT within groups among different time points ( Ftime=4.358, P=0.020).The 1-day postoperative, 1-week postoperative, 6-week postoperative corneal epithelial staining score were (1.40±0.81), (0.13±0.34), (0.00±0.00) points in diclofenac sodium group, and (1.38±0.89), (0.22±0.47), and (0.00±0.00) points in bromofenac sodium group.There was no statistically significant difference in the corneal epithelial staining score between the two groups after surgery ( Fgroup=0.110, P=0.741).There were statistically significant differences in corneal epithelial staining scores within groups among different time points ( Ftime=175.054, P<0.01).The 1-day postoperative, 1-week postoperative, 6-week postoperative anterior chamber flare classification were 1.13±0.51, 0.13±0.34, and 0.00±0.00 in diclofenac sodium group, and 1.02±0.34, 0.16±0.37, and 0.00±0.00 in bromofenac sodium group.There was no significant difference in the overall anterior chamber flash between the two groups ( Fgroup=0.045, P=0.507).There were statistically significant differences in anterior chamber flash within groups among different time points ( Ftime=322.331, P<0.001).There was no significant difference in the preoperative and 6-week postoperative macular fovea thickness between both groups ( t=-0.221, -0.374; both at P>0.05).The incidence of macular cystoid edema 6 weeks after operation was 0% in both groups.Subjects tolerated the two tested drugs well.Eight adverse events occurred in this study, all of which were mild postoperative IOP elevation, including 3 in diclofenac sodium group with an incidence of 6.67% and 5 in bromofenac group with an incidence of 11.1%.IOP returned to normal in all the patients 1 week after stopping the use of drug. Conclusions:Two nonsteroidal anti-inflammatory drugs are safe and effective for anti-inflammatory treatment after cataract phacoemulsification combined with IOL implantation.The new diclofenac sodium eye drops are more comfortable than bromfenac sodium eye drops.

Osteosarcoma,which primarily affects children and adolescents,is a highly malignant bone tumor with high rates of disability and mortality.Therefore,the exploration of biological markers related to its occurrence,development,and prognosis is crucial.Genome-wide association studies have revealed the vital role of genetic polymorphisms in the pathogenesis of osteosarcoma.This study aims to provide new insights into reliable biomarkers of osteosarcoma through the analysis of the functional single-nucleotide polymor-phisms of tumor-related genes.

Objective To investigate the current status of mini-CEX scores among students in the Elderly Service Man-agement program after completing the"Fundamentals of Nursing"course and analyze the influencing factors.Methods A total of 99 students from the Elderly Service Management program at the Wuming campus of Guangxi Medical University were selected as the study subjects.Assessment tools included a general information questionnaire,the Chinese version of the Mini Clinical E-valuation Exercise(mini-CEX),the Self-Rating Scale of Self-Directed Learning(SRSSDL),and a self-learning ability assess-ment scale.Stepwise linear regression analysis was employed to explore the factors affecting mini-CEX scores.Results The total mini-CEX score for the 99 students was 49.00(44.00,55.00).Stepwise linear regression analysis revealed that being a student leader,SRSSDL scores,self-learning ability,and teaching model were significant factors(P＜0.05),explaining 56.8％of the total variance.Conclusion The clinical comprehensive ability of students in the Elderly Service Management program requires enhancement,influenced by multiple factors including teaching model,self-learning ability,and self-directed learning capacity.

OBJECTIVE To establish the fingerprints of Tianma jiannao granules （TJG） and the method for content determination to evaluate the quality of TJG comprehensively combined with chemometric analysis. METHODS High-performance liquid chromatography （HPLC） was used to establish the fingerprints of 13 batches （S1-S3） of TJG and determine the contents of inosine， gastrodin， parishin B and parishin E. Cluster analysis， principal component analysis， and orthogonal partial least squares- discriminant analysis were performed using SPSS 20.0 and SIMCA 18 software； using variable importance projection （VIP） value greater than 1 as a criterion， marker components that affected quality were screened. RESULTS A total of 28 common peaks were identified in the 13 batches of TJG with similarities greater than 0.9， and 7 common peaks were identified， which were gastrodin， p-hydroxybenzyl alcohol， parishin B， parishin E， rhynchophylline， inosine and salidroside. The 13 batches of TJG were clustered into 3 categories， S1-S2， S8-S10 and S12 were clustered into one category； S3 and S7 were clustered into one category； S4-S6， S11 and S13 were clustered into one category. VIP of inosine was greater than 1. The contents of inosine， gastrodin， parishin B and parishin E were 62.637-176.677， 17.821-37.642， 5.748-16.077 and 5.660-13.510 μg/g. CONCLUSIONS The established HPLC fingerprints and content determination method are stable， reliable and highly reproducible， which can be used to evaluate the quality of TJG in combination with chemometric analysis. Inosine may be a marker component that affects the quality of TJG. There are differences in the quality of 13 batches of TJG.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency， it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat， spleen and stomach damp-heat， and spleen deficiency is divided into deficiency of spleen yin， deficiency of spleen qi ， and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories，i.e. stomach-heat and spleen yin-deficiency， stomach-heat and spleen qi-deficiency， and stomach-heat and spleen yang-deficiency， and the main treatment methods are clearing and draining heat， nourishing yin and moistening intestine， clearing dampness and heat， strengthening spleen and qi， clearing dampness and heat， strengthening spleen and warming yang， respectively， with prescriptions as Maziren Pills （麻子仁丸）， Qinlian Pingwei Powder （芩连平胃散）， and Jiawei Lianli Decoction （加味连理汤） accordingly.

[Objective] To explore the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou, and to investigate the correlation between donation frequency and these factors. [Methods] A cross-sectional study was conducted among 13 042 whole blood donors from 17 street blood donation sites of Guangzhou Blood Center from May to August 2020. Descriptive analysis was used to describe the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou. Ordinal multinomial logistic regression model was used to analyze the correlation between donation frequency and these factors. [Results] It was found that some of 13 042 blood donors had unhealthy habits, such as 6.8% (698/10 214，2 828 missing values) had severe tobacco dependence, 30.6% (3 997/13 042) had low exercise levels, 38.8%（5 056/13 042）had poor sleep quality, and 2.2% (271/12 159，883 missing values) had alcohol dependence. In addition, 2.8% (364/13 042) and 1.3% (172/13 042) of the donors may have moderate to severe depression and anxiety symptoms, respectively. The results of the ordinal multinomial logistic regression model showed that exercise level was significantly negatively correlated with the degree of depression and anxiety among blood donors. With the decrease in exercise level, the possibility of depression and anxiety among donors increased significantly. BMI, household income, education level, marital status, donation frequency, alcohol consumption and smoking had no significant correlation with the mental health status of donors. [Conclusion] Improving the exercise habits of blood donors may help enhance their mental health level. It is recommended that blood station staff strengthen the content of exercise when providing health education to blood donors to maintain a healthy lifestyle. It also suggests that there may be a certain degree of under-diagnosis of mental health problems in the process of health consultation before blood donation, and conducting more comprehensive and effective mental health assessments for blood donors is recommended.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2％dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2％ DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.
