Pinellia ternata, belonging to the Pinellia genus within the Araceae family, is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation, necessitating urgent new variety protection efforts. The distinctness, uniformity, and stability (DUS) testing of the plant variety is the basis for protecting new plant varieties, and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata, agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years, and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits, 19 leaf traits, six flower traits, two fruit traits, two tuber traits, five bulbil traits, and one ploidy trait. These traits could be divided into 22 quality characters, 12 quantitative characters, and four pseudo-quantitative characters, as well as seven groups, including plants, leaves, flowers, fruit, tubers, bulbils, and ploidy. By searching for standard traits, 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties, safeguarding breeders' rights, and promoting the development of the P. ternata industry.

Objective:To evaluate the value of ultrasonography in the differential diagnosis of cystic biliary atresia (CBA) and choledochal cyst (CC) in infants.Methods:CBA or CC children <3 months of age diagnosed by surgery in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2015 to 2023 were collected, and the differences in general conditions and ultrasound manifestations between CBA group and CC group were retrospectively analyzed.Results:Among the 55 children, 30 were in CBA group and 25 were in CC group. The mean length diameter and width diameter of cysts in the CBA group were about (1.45±1.05)cm and (1.04±0.73)cm, respectively, which were significantly smaller than those in the CC group (5.41±2.98)cm and (3.21±2.90)cm ( P<0.001). The incidence of fibrous plaque (50.0%, 15/30) and abnormal gallbladder morphology (73.3%, 22/30) in the CBA group was significantly higher than that in the CC group [4.0%(1/25) and 16.0%(4/25), respectively]. The incidence of intrahepatic biliary mud deposition (52.0%, 13/25) and intrahepatic biliary duct dilation (64.0%, 16/25) in the CC group was significantly higher than that in the CBA group [0, 3.3%(1/30), respectively]. Conclusions:There are some differences in ultrasonography between CBA and CC children. The length and width of cysts in children with CC are significantly larger than those in children with CBA, and biliary mud deposits or intrahepatic bile duct dilatation are seen in the cysts. The incidence of fibrous plaque and abnormal gallbladder morphology in CBA children is significantly higher than that in CC children.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

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).

IgA nephropathy (IgAN) is one common type of glomerulonephritis caused by a deposition of immune complexes in mesangium and partial capillary loops. It is also an important risk factor for end-stage renal disease (ESRD). Kidney transplantation (KT) has been an ultimate treatment for IgAN patients progressing into ESRD. However, there is still a high risk of recurrence after transplantation. Currently no effective treatment is available for recurrent IgAN. This review summarized the latest researches of managing IgAN recurrence after KT, such as optimal treatment, immunosuppression, complement therapy and surgery.

Objective:
: The spontaneous intracerebral hemorrhage (ICH) remains a significant cause of mortality and morbidity throughout the world. The purpose of this retrospective study is to develop multiple models for predicting ICH outcomes using machine learning (ML).
Methods:
: Between January 2014 and October 2021, we included ICH patients identified by computed tomography or magnetic resonance imaging and treated with surgery. At the 6-month check-up, outcomes were assessed using the modified Rankin Scale. In this study, four ML models, including Support Vector Machine (SVM), Decision Tree C5.0, Artificial Neural Network, Logistic Regression were used to build ICH prediction models. In order to evaluate the reliability and the ML models, we calculated the area under the receiver operating characteristic curve (AUC), specificity, sensitivity, accuracy, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR).
Results:
: We identified 71 patients who had favorable outcomes and 156 who had unfavorable outcomes. The results showed that the SVM model achieved the best comprehensive prediction efficiency. For the SVM model, the AUC, accuracy, specificity, sensitivity, PLR, NLR, and DOR were 0.91, 0.92, 0.92, 0.93, 11.63, 0.076, and 153.03, respectively. For the SVM model, we found the importance value of time to operating room (TOR) was higher significantly than other variables.
Conclusion
: The analysis of clinical reliability showed that the SVM model achieved the best comprehensive prediction efficiency and the importance value of TOR was higher significantly than other variables.

Objective:To explore the risk factors related to acute rejection (AR) after pediatric kidney transplantation (KT).Methods:Retrospective analysis was performed for 189 pediatric KT recipients from September 2011 to August 2022.They were divided into two groups of AR (n=33) and non-AR (n=156).Univariate and multivariate Logistic regression analyses were performed for identifying potential risk factors of AR.And the effects of AR on graft function and survival were also examined.Results:During follow-ups, a total of 33(17.5%) patients developed AR with a 1-year cumulative incidence of AR of 16.9%(32/189).Univariate analysis revealed that median time on dialysis was longer in AR group than that in non-AR group (19 vs. 11 months, P=0.034).Median age of donors (12 vs. 24 months, P=0.033), median weight of donors (9.5 vs. 12 kg, P=0.025) and median donor/recipient body weight ratio (0.36 vs. 0.50, P=0.005) were lower in AR group than those in non-AR group.And the proportion of subtherapeutic tacrolimus (TAC) trough level was higher in AR group than that in non-AR group (45.5% vs. 21.2%, P=0.004).Multivariate regression analysis indicated that subtherapeutic TAC trough level was an independent risk factor for AR ( OR=2.977, 95% CI: 1.314-6.743, P=0.009).At the last follow-up, serum creatinine and eGFR were (78.4±24.3) vs. (74.6±24.7) μmol/L and (85.3±26.3) vs. (89.5±24.2) ml·min -1·1.73 m -2 in AR and non-AR groups respectively.There were no significant differences.1/5-year patient survival rate was both 97% in AR group and both 99.4% in non-AR group; 1/5-year graft survival rate both 90.9% in AR group and was 98.1% and 97.4% in non-AR group.No significant inter-group differences existed in patient and graft survival. Conclusions:Although an occurrence of early AR does not negatively impact graft outcomes, the incidence of AR remains high after pediatric KT.Therefore prompt diagnosis and treatment of AR should be strengthened.

Objective:To explore health utility value, evaluate health-related quality-of-life(QOL)of pediatric liver transplantation(LT)recipients and examine its influencing factors to provide rationales for related health economic evaluations.Methods:This cross-sectional QOL was conducted through a questionnaire in pediatric LT recipients aged 5-17 years.The interviewees undergoing initial LT from June 2013 to September 2021 were reviewed regularly.Those children and their parents unwilling to participate or failing to understand the contents of questionnaire were excluded.The questionnaire was designed on the basis of Child Health Utility 9D Instrument(CHU9D)and answered online by one of primary caregiver.Chinese score system of CHU9D was employed for converting the responses into health utility values and the influencing factors were analyzed.Univariate analysis was performed by nonparametric tests and multivariate analysis by multiple linear regression model. P<0.05 was deemed as statistically significant. Results:A total of 140 valid questionnaires were obtained.Mean age of pediatric LT recipients was(7.95±2.74)years and mean postoperative time(4.90±2.17)years.Among them, 19 cases had experienced acute rejection and 101(72.1%)cases were living-related LT recipients.CHU9D scale indicated that average health utility value was(0.85±0.14)points.Univariate analysis revealed that age( P=0.008), education level( P<0.001)and primary disease( P=0.010)influenced the postoperative level of QOL.Multivariate analysis indicated that QOL was correlated with education level(behind schedule: 95% CI: -0.146, -0.034, P=0.002; leave of absence: 95% CI: -0.251, -0.068, P=0.001). Conclusions:Health utility of pediatric LT recipients is high with an excellent QOL.Poor QOL is associated with absence from school or dropping out of school.
