Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

Objective:To investigate the current situation of nurses′ death attitudes, death competency and death education need in tertiary care hospitals, and analyze their relationship and to provide suggestions and guidance for clinical death education.Methods:This was a cross-sectional survey. From January to March 2022, a random sample of 1 902 nurses from five tertiary hospitals in Hunan Province Changsha City was selected as the study population. The general information questionnaire the Death Attitude Profile-Revised (DAP-R), Coping with Death Scale (CDS) and Death Education Needs Scale were used to investigate the current situation of nurses′ death attitudes, death competency and death education needs in tertiary hospitals, and the correlations among them were analyzed.Results:The 1 837 valid questionnaires were finally collected. The total score of death attitude was (91.37 ± 11.26) points, the total score of death competency was (109.25 ± 21.67) points and the total score of death education needs was (214.13 ± 28.64) points. Natural acceptance was positively correlated with death education needs ( r=0.458, P<0.05), escape acceptance was positively correlated with death education needs ( r=0.312, P<0.05), convergent acceptance was positively correlated with death education needs ( r=0.347, P<0.05), death avoidance was negatively correlated with death education needs ( r=-0.291, P<0.05), and death competency was positively correlated with death education needs ( r=0.356, P<0.05). Conclusions:Nurses had some degree of positive death attitudes, moderate level of death competency and higher need for death education. The death education need was positively correlated with positive death attitudes and death competency. The death education should be strengthened to cultivate positive death attitudes and improve death competency to improve the quality of end-of-life care and the quality of patient death.

Liver is the central hub regulating energy metabolism during feeding-fasting transition. Evidence suggests that fasting and refeeding induce dynamic changes in liver size, but the underlying mechanisms remain unclear. Yes-associated protein (YAP) is a key regulator of organ size. This study aims to explore the role of YAP in fasting- and refeeding-induced changes in liver size. Here, fasting significantly reduced liver size, which was recovered to the normal level after refeeding. Moreover, hepatocyte size was decreased and hepatocyte proliferation was inhibited after fasting. Conversely, refeeding promoted hepatocyte enlargement and proliferation compared to fasted state. Mechanistically, fasting or refeeding regulated the expression of YAP and its downstream targets, as well as the proliferation-related protein cyclin D1 (CCND1). Furthermore, fasting significantly reduced the liver size in AAV-control mice, which was mitigated in AAV Yap (5SA) mice. Yap overexpression also prevented the effect of fasting on hepatocyte size and proliferation. Besides, the recovery of liver size after refeeding was delayed in AAV Yap shRNA mice. Yap knockdown attenuated refeeding-induced hepatocyte enlargement and proliferation. In summary, this study demonstrated that YAP plays an important role in dynamic changes of liver size during fasting-refeeding transition, which provides new evidence for YAP in regulating liver size under energy stress.

Preoperative and postoperative corneal condition, UCVA, best corrected visual acuity(BCVA)and the values of corneal endothelial, maximum keratometry(Kmax), thinnest corneal thickness(TCT), anterior and posterior surfaces of the cornea K1, K2, biomechanically corrected intraocular pressure(bIOP), applanation time 1(A1T), applanation length 1(A1L), applanation velocity 1(A1V), applanation time 2(A2T), applanation length 2(A2L), applanation velocity 2(A2V), highest concavity deformation amplitude(HCDA), radius at highest curvature(HCR), highest concavity peak distance(HCPD)and stiffness parameter at first applanation(SP-A1)were recorded.RESULTS: There were differences between UCVA(LogMAR; 1.06±0.49, 0.78±0.39)and BCVA(LogMAR; 0.48±0.34, 0.38±0.29)before and at 6mo after surgery(P<0.05), but there were no differences in corneal endothelial cells(2917.39±288.38 vs. 2959.19±336.27 cells/mm2, P=0.477). There were differences among Kmax, TCT, anterior surface K1 and K2 and posterior surface K1 before and after surgery(P<0.05), and all increased at 1mo after surgery then returned to preoperative level at 3mo after surgery, while there was no difference in the posterior K2. Furthermore, there were statistical significance in A1T, HCPD and SP-A1 before and after surgery(P<0.05), while there were no statistical significance in A1L, A1V,A2T, A2L, A2V, HCDA, HCR and bIOP(P>0.05).CONCLUSION: Epithelial-off accelerated CXL can prevent the progression of keratoconus within half year after surgery, and it has certain safety.

To explore the effect of Internet+diet self-management intervention technology on the blood pressure control of hypertension high-risk population through the intervention of hypertension high-risk population in Haikou City community, so as to provide scientific evidence for the prevention and treatment of cardiovascular diseases (CVD). The multi-stage cluster sampling method was used, and 295 hypertension high-risk participants were recruited from 15 communities in Haikou City from July to December 2021. The 15 communities were randomly divided into three groups: blank group, traditional group and Internet plus group by random number table method. The blank group referred to the group (99 participants) that did not take special intervention measures but the routine interventions in accordance with the "National Basic Public Health Service Standards (the Third Edition) Health Education Service Standards". On the basis of the blank group, the traditional group (95 participants) was intervened by giving additional traditional methods such as holding lectures and distributing popular science books. The Internet plus group (101 participants) was given additional Internet measures on the basis of the intervention of the traditional group. After 6 months, questionnaires, laboratory biochemical tests, and physical measurements were conducted. SPSS 25.0 software was applied for data analysis. Measurement data that followed normal distribution were statistically described by using mean±standard deviation, analysis of variance was used for inter group comparisons before intervention, analysis of covariance was used for inter group comparisons after intervention, and Bonferroni adjustment was used for pairwise comparisons between groups. Measurement data that did not follow the Normal distribution were represented by M (Q₁, Q₃). The rank sum test was used for inter group comparison. The k sample Kruskal Wallis single factor ANOVA was used to compare the distribution between different groups. Counting data were described by composition ratio or rate. Under the premise of balanced comparison between groups before intervention, Chi-squared test was used for inter group comparison after intervention, and Bonferroni adjustment method was used for pairwise comparison between groups. The results showed that a total of 295 participants were included, with males accounting for 35.6% (105) and females accounting for 64.4% (190). The age ranged from 55 to 74 years old, with an average age of (64.69±5.73) years. The number of married accounted for 95.6% (282 participants). There were no statistically significant differences in gender, age, family history, education level, occupation, marital status, drinking habits, regular exercise, dietary status, SBP (systolic blood pressure), DBP (diastolic blood pressure), pulse pressure difference, BMI (body mass index), folic acid, and 24-hour urine sodium among the three groups upon enrollment (P values>0.05). After the intervention, the drinking rate was as follows: Internet plus group (29, 28.7%)2=28.948, P<0.001); Regular exercise rate was higher in the Internet plus group (37, 36.6%) than in the traditional group (18, 18.9%) and the blank group (16, 16.2%) (χ²=13.476, P=0.001). After the intervention, compared with the participants in the blank group, the intake of energy, carbohydrate, dietary fiber, sodium and folic acid in the Internet plus group were significantly different (all P<0.05); Compared with the participants in the traditional group, the energy, carbohydrate and dietary fiber intake of the participants in the Internet plus group were significantly different (all P<0.05). After the intervention, the blood pressure levels in the Internet plus group [ SBP: (128.95±6.55) mmHg, DBP: (79.88±5.75) mmHg ] and the traditional group [ SBP: (129.63±8.41) mmHg, DBP: (79.77±7.73) mmHg ] were lower than those in the blank group [ SBP: (132.93±8.41) mmHg, DBP: (82.42±7.76) mmHg ] (SBP: F=9.417, P<0.001; DBP: F=6.967, P=0.001), the 24-hour urinary sodium level in the Internet plus group (143.63±38.58) mmol/24 h was lower than that in the traditional group (163.31±35.67) mmol/24 h and the blank group (154.14±35.52) mmol/24 h (F=11.509, P<0.001). In conclusion, compared with the traditional intervention mode, the "Internet plus diet self-management intervention" mode is more likely to promote the development of a healthy lifestyle for people at high risk of hypertension, effectively improve blood pressure and 24-hour urine sodium level, and facilitate CVD prevention.

Objective　Acinetobacter baumannii (A. baumannii) is a commonly infective bacterium in the hospital. This study aims to analyze its molecular epidemiological characteristics, detect the carrying rate of efflux pump and regulatory protein genes, and investigate the effects of tigecycline on the efflux pump and expression of regulatory protein genes.　Methods　A total of 183 A. baumannii strains were collected from inpatients of the affiliated hospital of Jiangsu University from May 2017 to March 2019. They were divided into an antimicrobial-resistant group (one or more antimicrobial-resistant strains, 139 strains) and a sensitive group (the drugs in the drug sensitivity test were all non-resistant strains, 44 strains). Repeated sequence PCR was used for homology analysis of the strains, and pulse-field gel electrophoresis (PFGE) was used as the gold standard for homology analysis to verify and compare some strains. PCR was used to detect the occurrence of drug resistance-related genes. Based on homology analysis, efflux pump carrying rate detection and antibiotics sensitivity test results, 6 clinical strains carrying all efflux pump genes but different resistance phenotypes were selected as experimental strains, including sensitive strains (SAB), the multidrug resistance strain (MDRAB) and the extensively drug-resistant strain (XDRAB). All strains were induced in vitro with the minimum inhibitory concentration (MIC) of tigecycline. The induced strains were categorized as induction group, and the same strains cultured in LB agar without tigecycline was used as a control group. MIC was used to analyze the tigecycline susceptibility, and RT-qPCR was used to detect the gene expression of efflux pumps, such as TetB, AbaQ and regulatory proteins (AdeS and BaeS), in drug-resistant strains.　Results　Homology analysis showed that there were 45 clonal groups in the detected clinical isolates, with no obvious outbreak of epidemic clonal groups. Efflux pumps and regulatory proteins were widely distributed in the clinical isolates, and the expression of AdeB, TetB, AbeS, AdeS in MDRAB and XDRAB is significantly higher than that insensitive group SAB. Continuous in vitro induction with tigecycline could increase the antimicrobial resistance of some clinical strains and even significantly increase the expression levels of efflux pumps and regulatory proteins.　Conclusion　A. baumannii is widely distributed in the clinic, and efflux pumps and regulatory proteins might play an important role in drug resistance process. The unreasonable use of tigecycline could enhance the tolerance of A. baumannii by up-regulating the expression of some bacterial efflux pumps.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective: To explore a predictive nomogram for the result of prostate biopsy based on Prostate Imaging Reporting and Data System version 2(PI-RADS v2)combined with prostate specific antigen (PSA) and its related parameters, and to assess its ability to diagnose prostate cancer by internal validation. Methods: We retrospectively analyzed the clinical data of 509 patients who underwent transrectal prostate biopsy guided by ultrasound during the period from January 2014 to December 2018 in the Department of Urology, First Affiliated Hospital of Xiamen University. In 509 cases, the mean age was (68.1±7.2) years. The mean prostate volume(PV) was (55.8±30.7) ml. The mean tPSA value was (19.86±18.94) ng/ml. The mean value of fPSA was (2.63±3.60) ng/ml and the mean f/tPSA was 0.14±0.08. The mean PSAD was (0.46±0.52) ng/ml2. Based on the PI-RADS v2, score 1 point have 37 cases, score 2 point have 131 cases, score 3 point have 152 cases, score 4 point have 102 cases, score 5 point have 87 cases. Of these patients, we randomly selected 80% (407 cases) as development group, and the other 20% (102 cases) as validation group. Univariate and multivariate logistic regression analysis of the development group was performed to identify the independent influence factors that can predict prostate cancer (PCa), thereby establishing a predictive model for the result of prostate biopsy. In the development group, validation group and tPSA was between 4.1-20.0 ng/ml, the model was evaluated by analyzing the receiver operating characteristic (ROC) curve, calibration curve and decision curve, and compared to PSA, fPSA, f/tPSA, PSAD, PI-RADS v2. Results: Among the 509 patients enrolled in the study, the detection rate of PCa was 43.0% (219/509). In the development group, the logistic regression analysis demonstrated that patient age (OR=1.113), f/tPSA (OR=0.004), PV (OR=0.986), PSAD (OR=11.023), digital rectal examination (DRE) texture (OR=2.295), transabdominal ultrasound (TAUS) with or without hypoechoic (OR=2.089), and PI-RADS v2 (OR=1.920) were independent factors for PCa (P<0.05). The nomogram based on all variables was established. In the development group, the area under the curve (AUC) of the model (0.883) was greater than those of tPSA (0.686), fPSA (0.593), f/tPSA (0.626), PSAD (0.777), PI-RADS v2 (0.761). In the validation group, the area under the curve of the model (0.839) was greater than those of tPSA (0.758), fPSA (0.666), f/tPSA (0.648), PSAD (0.832), PI-RADS v2 (0.803). In patients whose tPSA was between 4.1-20.0 ng/ml, the area under the curve of the model (0.801) was greater than those of tPSA (0.570), fPSA (0.426), f/tPSA (0.657), PSAD (0.707), PI-RADS v2 (0.701). The calibration curve of the nomogram indicated that the prediction curve was basically fitted to the standard curve, and the Hosmer-Lemeshow showed thatχ²=5.434, P=0.710, both suggested that the prediction model had better calibration ability. The decision curve showed that the model based on PI-RADS v2 had high clinical application value. Conclusions The nomogram based on PI-RADS v2 had a high predictive value for prostate cancer and could significantly improve the diagnostic performance. It had better diagnostic value than PSA and its related parameters. It also provided important guidance for the prostate cancer on clinical treatment of patients to some extent.
