Objective To investigate the predictive value of serum oncogene[proliferation-related gene(C-myc),transformation gene(N-ras),silk/threonine kinase 1(PLK1),fibroblast growth factor 2(FGF2)]protein levels in patients with hepatitis B associated hepatocellular carcinoma(HCC)after hepatic arterial chemoem-bolization(TACE).Methods A total of 127 patients with hepatitis B-associated hepatocellular carcinoma ad-mitted to a hospital from July 2016 to January 2021 were selected and divided into death group and survival group according to the follow-up results.The serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels were determined by double-antibody sandwich enzyme-linked immunosorbent assay.Univariate and multivari-ate Cox analysis were used to analyze the risk factors of serum oncogene C-myc,N-ras,PLK1 and FGF2 pro-tein levels in patients with hepatitis B-associated hepatocellular carcinoma after TACE.The receiver operating characteristic curve was used to evaluate the prognostic value of the serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels,and the patients were divided into high expression group and low expression group ac-cording to the corresponding cutoff value.Kaplan-Meier survival curve was used to evaluate the prognosis of different serum oncogene C-myc,N-ras,PLK1 and FGF2 protein level.Results Multivariate Cox regression a-nalysis indicated that TNM stage Ⅲ to Ⅳ(HR=2.998,95％CI:1.239-7.257),portal vein metastasis(HR=3.737,95％CI:1.941-7.193),abdominal metastasis(HR=3.482,95％CI:1.709-7.097),Child-Pugh grade B(HR=2.587,95％CI:1.045-6.406),high serum oncogene C-myc protein level(HR=1.224,95％CI:1.090-1.374),high serum oncogene N-ras protein level(HR=1.218,95％CI:1.097-1.353),high serum oncogene PLK1 protein level(HR=1.237,95％CI:1.110-1.379)and high serum oncogene FGF2 protein level(HR=1.141,95％CI:1.060-1.228)were independent risk factors for the prognosis of hepatitis B-asso-ciated hepatocellular carcinoma patients after TACE(all P＜0.05).The overall survival rate of low expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level was significantly higher than that of high expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level,the difference was statistically significant(all P＜0.001).Conclusion Serum oncogene C-myc,N-ras,PLK1,FGF2 protein levels have predic-tive value for the prognosis of patients with HBV-related liver cancer after TACE.

Objective:To investigate the relationship between 21-gene recurrence risk score (21-Gene RS) and the prognosis and clinicopathological features of hormone receptor (HR) positive, HER2-negative early breast cancer patients who did not receive neoadjuvant therapy.Methods:A total of 469 patients with HR positive and HER2-negative early breast cancer who received surgical treatment in the First Affiliated Hospital, Zhejiang University School of Medicine from January 2014 to October 2017 were selected. Their clinicopathological data were retrospectively analyzed. Tumor tissue samples were collected from patients, and the expression of 21-gene was detected by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). The 21-Gene RS was calculated according to the Trial Assigning Individualized Options for Treatment (TAILORx) RS grouping and National Surgical Adjuvant Breast and Bowel Project B-20 (NSABP B-20) RS grouping principles. Patients were divided into low (21-Gene RS<11 or 21-Gene RS<18), intermediate (11≤21-Gene RS<26 or 18≤21-Gene RS<31) and high (21-Gene RS≥26 or 21-Gene RS≥31) risk groups, and the clinicopathological features and prognostic differences of patients in different risk groups were compared. Statistical data were compared by chi-square test. Survival analysis was performed using Kaplan-Meier curve analysis and the differences between groups were compared using Log-rank test. Multivariate analysis was conducted by COX regression analysis.Results:Based on TAILORx RS grouping, the proportions of low-risk, intermediate-risk and high-risk groups among the 469 patients were 18.8% (88/469), 48.2% (226/469) and 33.0% (155/469), respectively. Based on NSABP B-20 RS grouping, the proportion of low-risk, intermediate-risk and high-risk groups were 43.1% (202/469), 37.5% (176/469) and 19.4% (91/469), respectively. The association of 21-Gene RS with histological grading, luminal typing, Ki-67 expression, and chemotherapy and treatment modalities were statistically significant ( P<0.05) regardless of TAILORx RS grouping or NSABP B-20 RS grouping. Kaplan-Meier survival curve suggested poor prognosis in high-risk group ( P<0.05, Log-rank test). Multivariate COX regression analysis showed that surgical method and 21-Gene RS were risk factors affecting the prognosis of patients. Conclusions:21-Gene RS is significantly associated with the prognosis of patients with HR-positive, HER2-negative, early-stage breast cancer not receiving neoadjuvant therapy, as well as with their clinicopathological characteristics such as patients′ histologic grade, luminal typing, Ki-67 expression, and whether or not they are treated with chemotherapy or other treatment modalities.The 21-Gene RS threshold of 11 and 26 or 18 and 31 can be used to grade the prognosis in Chinese patients with early-stage breast cancer. More researches are needed to guide the selection of postoperative adjuvant therapy for patients with HR-positive and HER2-negative early-stage breast cancer.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective To investigate the effect of recombinant tissue-type fibrinolytic plasminogen activator(rt-PA)intravenous thrombolysis followed by the addition of tirofiban at different times on neurovascular function in patients with acute ischemic stroke(AIS).Methods A total of 120 patients with AIS admitted to the Neurology Department of Beijing Geriatric Hospital from March 2020 to March 2023 were selected as the research subjects,and all patients received intravenous throm-bolysis with rt-PA.According to the different times of adding tirofiban after intravenous thrombolysis treatment,the patients were divided into the early group(within 6 hours after thrombolysis,n=52),intermediate group(6-12 hours after thrombolysis,n=38)and late group(12-24 hours after thrombolysis,n=30).The neurological function[National Institutes of Health Stroke Scale(NIHSS)score,modified Rankin scale(mRS)score],vascular function[von Willebrand factor(vWF),vascular endothelial cell-calcineurin(VE-cadherin),thrombomodulin(TM)],inflammatory factors[high-sensitivity C-reactive protein(hs-CRP),homocysteine(Hey),interleukin-1 β(IL-1 β)]levels were compared among the three groups before and after treatment.The incidence of adverse events during treatment was recorded.Results Before treatment,there was no significant difference in NIHSS and mRS scores of patients among the three groups(P＞0.05);NIHSS and mRS scores of patients in the three groups after treatment were significantly lower than those before treatment(P＜0.05);after treatment,NIHSS and mRS scores of patients in the early group were significantly lower than those in the intermediate and late groups,and those in the intermediate group were significantly lower than those in the late group(P＜0.05).Before treatment,there was no statistically significant difference in vWF,VE-cadherin,and TM levels of patients among the three groups(P＞0.05);the levels of vWF,VE-cadherin and TM of patients in the three groups after treatment were significantly lower than those before treatment(P＜0.05);after treatment,the levels of vWF,VE-cadherin,and TM of patients in the early group were significantly lower than those in the intermediate and late groups(P＜0.05);after treatment,the levels of vWF of patients in the late group was significantly higher than that in the intermediate group(P＜0.05),and there was no statistically significant difference in the levels of VE-cadherin and TM of patients between the intermediate group and late group(P＞0.05).Before treatment,there was no significant difference in the levels of hs-CRP,Hcy,and IL-1 β of patients among the three groups(P＞0.05);the levels of hs-CRP,Hcy,and IL-1 β of patients in the three groups after treatment were significantly higher than those before treatment(P＜0.05);after treatment,the levels of hs-CRP,Hcy,and IL-1 β of patients in the early group were significantly lower than those in the intermediate and late groups,and the levels of hs-CRP,Hcy,and IL-1 β of patients in the intermediate group were significantly lower than those in the late group(P＜0.05).During the treatment period,there was no significant difference in the incidences of symptomatic cerebral hemorrhage of patients among the three groups(P＞0.05);the incidences of reocclusion and cardiopulmonary complications in the early group were significantly lower than those in the intermediate group and late group(P＜0.05);there was no significant difference in the incidence of reocclusion and cardiopulmonary complications of patients between the intermediate group and late group(P＞0.05).Conclusion The addition of tirofiban at different times after rt-PA intravenous thrombolysis can promote the recovery of neurological function and vascular function in AIS patients,and also can inhibit the inflammatory mediator response,of which the best effect is achieved by the addition of tirofiban at an early stage after rt-PA intravenous thrombolysis.

Objective To explore the effects and mechanism of Shentao Ruangan Prescription on hepatocellular carcinoma.Methods MTT assay was used to detect the activity of Shentao Ruangan Prescription against HepG2 cells and the effects of PI3K/Akt/MAPK inhibitors(LY294002,Akti,MEKi,JNKi),apoptosis inhibitor(Z-VAD)and autophagy inhibitor(Wortmanin)in human hepatoma cells.),ferroptosis inhibitor(Ferrostatin-1)and cell necrosis inhibitor(Necrostatin-1)on the inhibition of HepG2 activity of human hepatoma cells by Shentao Ruangan Prescription.LDH method was used to detect the toxicity of Shentao Ruangan Prescription on HepG2 cells;Real-time PCR experiment tested the effect of Shentao Ruangan Prescription on the pyroptosis marker IL-1β in human hepatoma cells HepG2;Western blot experiment explored the effect of Shentao Ruangan Prescription on the Akt/ERK signaling pathway in human hepatoma HepG2 cells and the expression of Akt,ERK,P-ERK,the key proteins of apoptosis signaling pathway Caspase 3,PARP,Bcl2,Bax,and the expression of pyroptosis marker Cleavaged Caspase-1.Results Shentao Ruangan Prescription Can effectively inhibit the activity of human hepatoma HepG2 cells.LY294002,Wortmanin,Akti,MEKi,JNKi,Z-Vad,Ferrostatin-1,Necrostatin-1 had no significant effect on the inhibition of HepG2 activity by total extract(water extract),supernatant and precipitation.Shentao Ruangan Prescription promoted the release of LDH in human hepatoma HepG2 cells,causing cytotoxicity.It inhibited HepG2 pyroptosis markers in human hepatoma cells and the expression of IL-1β and Cleavaged Caspase-1 and decreased the protein expression of Akt in human hepatoma cells HepG2 but inversely increased Caspase3 protein expression.Conclusion Shentao Ruangan Prescription has the effect of inhibiting the activity of hepatocellular carcinoma cells and anti-hepatocellular carcinoma,and its mechanism may be related to inhibiting the expression of Akt and promoting the expression of Caspase3.At the same time,Shentao Ruangan Prescription reduces the expressions of IL-1β and Cleavaged Caspase-1,which may inhibit cell pyroptosis.The inhibitory effect of Shentao Ruangan Prescription on the activity of liver cancer cells is likely to be independent of programmed death modes such as autophagy and necrotizing apoptosis,and PI3K/Akt/MAPK signal transduction.The total extract of Shentao Ruangan Prescription has better anti-hepatoma activity than its water-soluble and alcohol-soluble components,and its water-soluble and alcohol-soluble components may have synergistic effect.

Objective:To explore the role of continuous renal replacement therapy (CRRT) combined with extracorporeal carbon dioxide removal (ECCO 2R) in the treatment of children with respiratory failure. Methods:The clinical data of 12 children with respiratory failure who were treated with CRRT+ECCO 2R in PICU of Jinan Children's Hospital from July 2020 to August 2022 were collected and analyzed retrospectively. The outcomes and the external pipeline usage of the patients were observed, and the blood gas analysis and ventilator parameters before 1 h and after 1, 6, 12 and 24 h of the treatment were compared by one-way ANOVA with LSD post hoc correction. Results:Six patients successfully withdrew from CRRT+ECCO 2R and mechanical ventilation, three patients were transferred to ECMO treatment. Three cases died after voluntary withdrawal of treatment, and two cases died due to treatment failure. The mortality rate was 41.7%. After continuous treatment of CRRT+ECCO 2R for 15 to 112 h, two cases experienced extracorporeal circuit obstruction. After 1 h of treatment, PaCO 2 decreased from (64.67±24.4) mmHg to (49.42±15.54) mmHg, pH increased from (7.28±0.20) to (7.38±0.11), FiO 2 decreased from (0.85±0.13) to (0.78±0.15), PC decreased from (19.42±4.34) cmH 2O to (17.75±4.00) cmH 2O. After 24 h of treatment, PaCO 2 decreased to (39.2±5.55) mmHg, pH increased to (7.41±0.04), FiO 2 decreased to (0.46±0.11), and PC decreased to (13.8±3.36) cmH 2O, and the differences were statistically significant compared with before treatment ( P < 0.05). Conclusions:The combination of CRRT and ECCO 2R therapy can safely substitute for partial lung ventilation/perfusion function, and play a role in protecting right heart function and improving lung-kidney interaction. It can be considered as an option for extracorporeal respiratory, circulatory, and renal support, and consequently has broad prospects.

The Salmonella strains isolated from the patients with foodborne illness were tested with serotyping，PFGE molecular classification and drug sensitivity test respectively according to《National foodborne illness surveillance workbook 2019》. Result A total of 3 191 cases of foodborne illness were analyzed. The pre-school children were the highest-risk group of foodborne diseases. Grain and grain product was the main suspicious contaminated food．The main location of eating place was family. A total of 330 samples were tested. The positive detection rate of foodborne illness was 20.30%（73/330）.The main pathogen were Rotavirus and Salmonella,and the detection rates were 11.21%(37/330) and 4.85%(16/330) respectively. The pre-school children were the group with the highest detection rate, which was 57.27% (63/110). The dominant serotype of the 14 Salmonella strains isolated from patients were Salmonella typhimurium and Salmonella enteritis. 14 different genotypes were obtained through PFGE classification and clustering. 64.29% (9/14) of Salmonella strains were multidrug-resistant strains. The drug resistance rates of ampicillin and tetracycline were the highest, which were 71.43%（11/14）and 64.29%（10/14）respectively. Conclusions The publicity and education of food safety should be strengthened and the surveillance network system of food-borne disease should be further improved according to the epidemiological and pathogenic characteristics of foodborne illness in Shiyan in 2019, and the use of clinical antibiotics should be controlled reasonably as well.

Objective:To investigate the diagnostic value of cardiac magnetic resonance (CMR) contrast medium perfusion and delayed contrast enhancement for early myocardial ischemia.Methods:Ninety-one patients with coronary artery stenosis diagnosed by coronary angiography (CAG) between March 2020 and March 2022 in Yiwu Central Hospital were included in this study. These patients underwent first-pass perfusion cardiac magnetic resonance imaging and delayed enhancement examination. Arrival time ( t0), accumulative signal intensity (ASI), relative peak enhancement rate (SI%), maximum intensity of signal enhancement (SIp), and maximum curve slope (α) were statistically analyzed in the CMR contrast agent normal-dose perfusion and low-dose perfusion segments. The diagnostic value of CMR contrast agent perfusion versus CAG for early myocardial ischemia was determined. The signal intensity was compared between enhanced and non-enhanced areas of CMR contrast agent perfusion. Results:There were significant differences in ASI, SI%, SIp, and Slope (α) between normal perfusion and low perfusion segments ( t = 9.62, 10.65, 8.67, 6.93, all P < 0.05). There was no significant difference in the detection rate of lesioned vessels in early myocardial ischemia between CMR contrast agent perfusion and CAG [50.42% (120/238) vs. 51.68% (123/238), χ2 = 1.32, P = 0.163). There was a significant difference in the detection rate of lesioned vessels in myocardial ischemia between CMR contrast agent perfusion and CAG ( χ2 = 15.31, P < 0.001, r = 0.71). The signal intensity value in the delayed enhancement segment was significantly higher than that in the non-delayed enhancement segment [(598.43 ± 40.19) vs. (298.64 ± 70.58), t =19.85, P = 0.001). Conclusion:CMR contrast agent perfusion can effectively evaluate the severity of early myocardial ischemia and locate the diseased blood vessels. Delayed enhancement can determine the location and area of early myocardial ischemia, and can objectively reflect the severity of myocardial ischemia.

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.

OBJECTIVE To compare the effectiveness，safety and economy of bovine pulmonary surfactant （PS） and porcine PS in the treatment of preterm neonates with respiratory distress syndrome （RDS）. METHODS Retrieved from PubMed，Embase， Cochrane Library，CNKI，SinoMed，Wanfang and health technology assessment （HTA） organization websites and relevant database， HTA report，systematic review/meta-analysis and pharmacoeconomic study about bovine PS versus porcine PS in the treatment of preterm neonates with RDS were included from the inception to Feb 2022. Data extraction and quality evaluation were carried out for the included literature，and then research results were summarized and analyzed descriptively. RESULTS A total of 1 HTA report，6 systematic reviews/meta-analyses，and 6 pharmacoeconomic studies were included. There appeared to be no significant differences between bovine PS and porcine PS in terms of time staying in neonatal intensive care unit and extra-pulmonary outcomes. In terms of PS re-treatment，blood gas index，total effective rate and the incidence of patent ductus arteriosus，porcine PS was superior to bovine PS. Results from other indicators，such as mortality， the incidence of bronchopulmonary dysplasia，air leakage syndrome，pulmonary hemorrhage，were still controversial. In terms of economy，there was no statistical difference in average hospital charges and administration cost per dose between two groups （P＞0.05）； compared with porcine PS，mean wastage cost per dose of bovine PS was higher （P＜0.001），and 24 h treatment cost of bovine PS was lower （P＜0.05）； the results of average medication cost were controversial. CONCLUSIONS The effectiveness， safety and economy of bovine PS are found to be similar or inferior to porcine PS. It is not certain whether the inferiority has clinical significance.
