Phosphatase and tensin-homolog deleted on chromosome 10 (PTEN) is an important cancer suppressor gene. Its pathogenic mutation leads to PTEN hamartoma tumor syndrome (PHTS), a rare syndrome also known as Cowden syndrome, which is relevant to early-onset hereditary breast cancer (BC). In this paper, we report three patients with unilateral multicentric BC and synchronous and metachronous bilateral BC who harbored PTEN gene mutations, and summarize the clinical manifestations, pathological characteristics, diagnosis, treatment and follow-up outcomes to provide reference for management of PTEN gene mutation-related BC among the Cowden syndrome population.

Objective:To identify the risk factors and to construct a predictive model for early postnatal mortality (with the first 7 days of life) in extremely preterm infants.Methods:This retrospective study involved 244 extremely preterm infants with a gestational age of 22 to 27 weeks and 6 days, born at the Affiliated Hospital of Jining Medical College from January 2017 to December 2022. They were divided into an early survival group ( n=140) and an early mortality group ( n=84), based on survival for ≥7 days after birth. LASSO and logistic regression were used to select risk factors for early mortality. A nomogram predictive model was constructed using the R software program. The goodness-of-fit tests, area under the curve (AUC), calibration curves, and decision curves were used to evaluate its performance and clinical usefulness. Results:LASSO regression and multivariate logistic regression analyses showed that breech delivery ( OR=3.055, 95% CI: 1.125-8.296), intubation in the delivery room ( OR=4.320, 95% CI: 1.328-14.053), diagnosis of grade Ⅲ-Ⅳ neonatal respiratory distress syndrome within 6 h after birth ( OR=11.552, 95% CI: 3.056-43.677), and use of adrenaline in the delivery room ( OR=10.706, 95% CI: 1.454-78.816) were risk factors for early mortality in extremely preterm infants. Conversely, large gestation age ( OR=0.234, 95% CI: 0.125-0.436), antenatal administration of corticosteroids to promote fetal lung maturity ( OR=0.046, 95% CI: 0.014-0.145), and the use of pulmonary surfactant within 6 h after birth ( OR=0.021, 95% CI: 0.004-0.122) were protective factors against mortality. The goodness of fit test of the early death risk nomogram prediction model for extremely preterm infants indicates a good fit ( P=0.702). The AUC of the model was 0.963 (95% CI: 0.943-0.983), with a sensitivity of 0.904 (95% CI: 0.806-0.949), specificity of 0.892 (95% CI: 0.829-0.938), and accuracy of 0.880. Decision curve analysis indicated that a threshold probability>2% would yield a net benefit. Conclusions:Breech delivery, intubation in the delivery room, use of adrenaline in the delivery room, and the diagnosis of grade Ⅲ-Ⅳ neonatal respiratory distress syndrome within 6 h post-birth are independent risk factors for early mortality in extremely preterm infants. Large gestational age, antenatal administration of corticosteroids to promote fetal lung maturity and use of pulmonary surfactant within 6 h after birth are protective factors. The constructed prediction model based on the aforementioned factors can quantitatively, conveniently, and intuitively assess the risk of early mortality in extremely preterm infants.

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Abstract: Objective　To develop a real-time fluorescent quantitative RT-PCR (qRT-PCR) method for qualitative and quantitative Chikungunya virus (CHIKV) analysis. Methods Based on the systematic analysis of the genomic sequences of Chikungunya and its related arboviruses, the specific nucleic acid sequences for Chikungunya virus were screened and identified, and then the primers and TaqMan probe were designed. Meanwhile, the human GAPDH gene was used as an internal reference. The reaction system for qRT-PCR was systematically optimized by L9(34) orthogonal design, and a rapid detection method for Chikungunya by qRT-PCR based on TaqMan probe methods was established. The sensitivity, specificity, reproducibility, and coverage of the established method were analyzed in detail. The standard curve was made, and the absolute quantitative method was established using the cloned nucleic acid fragments as positive samples. Results　A real-time fluorescent quantitative RT-PCR assay was developed for the qualitative and quantitative analysis of Chikungunya virus. The reaction system included Chikungunya virus and reference internal gene specific primers and probe, RT/Taq enzyme mixture, reaction buffer, and negative and positive reference. The established method obtained positive results with the ROSS strain of ECSA subtype, LR2006 strain of IOL branch, 181/25 strain of Asian type and Dongguan 2010 epidemic strains of Chikungunya virus, but there was no cross-reaction with other 18 arboviruses belonging to Flaviviruses, Alphaviruses and Bunyavirus. The minimum detection limit of the established method was 5.80 copies/mL, and a linear relationship was observed between the amount of input plasmid DNA and fluorescence signal value over a range of 5.80×102 copies/mL to 5.80×1010 copies/mL, and the correlation coefficient was 0.999 5. The qRT-PCR amplification efficiency was 91%, and the intra-assay variations and inter-assay variations were 0.01-0.07 and 0.03-0.11, respectively. Conclusions　The TaqMan qRT-PCR method developed in this study can qualitatively and quantitatively detect Chikungunya virus rapidly with specificity and sensitivity, providing a technical method for the prevention and control of this viral disease.

AIM: To construct and validate a diagnostic model for early detection of keratoconus based on parameters in Sirius.METHODS: The study comprised of 46 early keratoconus eyes(including 20 right eyes and 26 left eyes in 34 patients)and 46 age- and gender-matched normal eyes(including the right eyes of 46 patients)in the prediction group. The predictive index was constructed using LASSO and Logistic regression analyses based on the topographic, pachymetric and aberrometry variables of Sirius. There were 23 early keratoconus eyes categorized as suspected keratoconus cases by Sirius(including 12 right eyes and 11 left eyes in 23 patients)and 23 age- and gender-matched normal eyes(including the right eyes of 23 patients)included in the application cohort. External validation of predictors was performed for the application cohort.RESULTS: Sirius Keratoconus Index(SKI)was calculated based on the minimum corneal thickness and symmetry index back of Sirius. Highest AUC values were obtained in the prediction group(AUC=0.932)after Logistic regression analysis. The cut-off value of SKI was set at 0.44. Then, the receiver operating characteristic(ROC)curve, calibration plot and nomogram of the diagnostic formula were analyzed for the prediction cohort in detail. Finally, the accuracy of the SKI was evaluated in the application cohort; the sensitivity was 91% and the specificity was 96%.CONCLUSION: SKI based on minimum corneal thickness and symmetry index back of Sirius is a simple and effective method for early detection of keratoconus in the preoperative screening for refractive surgery.

OBJECTIVE: To analyze the clinical features of acute myeloid leukemia (AML)/high-risk myelodysplastic syndrome (MDS) patients aged over 60 years old. METHODS: The clinical data of 61 elderly newly diagnosed patients with AML and high-risk MDS who submitted to the Department of Hematology/Oncology of the First Affiliated Hospital of Tsinghua University from January 2009 to April 16, 2021 were retrospectively analyzed. These patients were divided into chemotherapy group (45 cases) and supportive treatment group (16 cases). The overall survival (OS) was analyzed by Kaplan-Meier method, and the prognostic factors of survival were analyzed by multivariate Cox regression. RESULTS: After 2 cycles of induction chemotherapy, the complete remission (CR) rate was 37.8% (17/45), and overall response rate was 62.2% (28/45) in the chemotherapy group. The median OS in the chemotherapy group and supportive treatment group was 11.3 (0.07-43) and 1.6 (0.33-7.72) months, respectively (P<0.001). The median OS in patients who reached CR or did not reach after 1 cycle of induction chemotherapy was 19.8 (10-30.63) and 8.17 (0.07-43) months, respectively (P<0.05), while after 2 cycles was 22.7 (4.2-43) and 7.26 (0.07-26) months, respectively (P<0.001). Univariate analysis showed that age > 80 years old, CCI score > 2, PS score > 2 and supportive treatment were the adverse prognostic factors for OS. Further multivariate analysis suggested that chemotherapy was the only independent prognostic factor for OS (HR=0.140, 95%CI: 0.048-0.409, P<0.001). In the chemotherapy group, univariate analysis showed that CCI score > 2 and failure to reach CR after induction chemotherapy were poor prognostic factors. Multivariate analysis showed that CCI score > 2 (HR=0.139, 95%CI: 0.050-0.384, P<0.001) and failure to achieve CR after induction chemotherapy (HR=0.103, 95%CI: 0.041-0.259, P<0.001) were the adverse prognostic factors for OS. The patients were tolerant to side-effect of chemotherapy. CONCLUSION Appropriate chemotherapy can prolong the survival of elderly patients with AML and high-risk MDS.

Objective:To explore the quality management strategy of clinical blood utilization by analyzing the quality control indexes of clinical blood transfusion in Hubei province from 2018 to 2020.Methods:The quality control indexes of clinical blood utilization in 244 secondary or above hospitals in Hubei province from 2018 to 2020 were investigated, including the number of professional and technical personnel per thousand units of blood transfusion, the internal quality control rate of blood transfusion compatibility test, the participation rate of external quality evaluation in blood transfusion compatibility test, the per capita blood consumption of discharged patients, and the development rate of autologous blood transfusion for patients undergoing surgery, and the differences of each index were compared and analyzed.Results:The indexes in Hubei province showed an increasing trend from 2018 to 2020, but there was no significant difference( P>0.05). The distribution of each index in Hubei province was unbalanced( P<0.05). The average blood consumption of discharged patients(0.13±0.14 U), the internal quality control rate of blood transfusion compatibility test(84.92%), the participation rate of external quality evaluation of blood transfusion compatibility test(93.65%) and the development rate of autologous blood transfusion(55.56%) in the tertiary hospitals were significantly higher than those in the secondary hospitals(0.09±0.10 U, 43.22%, 55.08%, 29.66%), while the number of professional and technical personnel of blood transfusion in thousand units(1.34±1.43) in the tertiary hospitals was significantly lower than that in secondary hospitals(2.41±2.39)( P<0.05). The average blood consumption of discharged patients(0.12±0.11 U), the participation rate of external quality evaluation of blood transfusion compatibility(82.18%) and the development rate of autologous blood transfusion(62.64%) in general hospitals were significantly higher than those in specialized hospitals(0.08±0.13 U, 68.57%, 27.14%), while the number of professional and technical personnel in thousand units of blood transfusion(1.44±1.60) was significantly lower than that in specialized hospitals(2.88±2.53)( P<0.05). The internal quality control rate(73.73%), the participation rate of external quality evaluation(87.10%) and the development rate of autologous blood transfusion(52.07%) in public hospitals were significantly higher than those in private hospitals(29.63%, 51.85%, 25.93%), however, the number of professional and technical personnel in blood transfusion(1.70±1.98) was lower than that in private hospitals(3.95±3.21)( P<0.05). Conclusions:The overall quality of clinical blood utilization in Hubei has been steadily increasing. However, the quality of clinical blood was not balanced among different areas. The overall clinical blood utilization quality of tertiary hospitals was significantly higher than the secondary hospitals, the general hospitals was significantly higher than the specialized hospitals, and the public hospitals was significantly higher than the private hospitals. The professional and technical personnel of blood transfusion in tertiary, general and public hospitals need to be strengthened.

ObjectiveTo investigate the clinical effect of laparoscopic splenectomy and pericardial devascularization (LSPD) in patients with portal hypertension and the long-term effect of LSPD. MethodsA total of 40 portal hypertension patients with Child-Pugh A/B liver function who received LSPD in The First Hospital of Jilin University from August to December 2017 were enrolled as surgical group, and 44 portal hypertension patients with Child-Pugh A/B liver function who received conservative treatment during the same period of time was enrolled as internal medicine group. The patients were followed up to June 30, 2019, and liver function parameters, upper gastrointestinal bleeding, and portal vein thrombosis were recorded for all patients at each time point. The t-test was used for comparison of normally distributed continuous data between two groups; an analysis of variance was used for comparison between multiple groups, and the Bonferroni test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution; between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups. The chi-square test was used for comparison of categorical data between groups. ResultsAt 6, 12, and 24 months after discharge, compared with the internal medicine group, the surgical group had a significantly higher level of cholinesterase (t=3.527, 3.849, and 5.555, all P＜0.05) and a significantly lower Child-Pugh score (t=2.498, 2.138, and 2.081, all P＜0.05). Compared with the internal medicine group at 12 and 24 months after discharge, the surgical group had a significantly higher level of albumin (t=3.120 and 2.587, both P＜0.05) and a significantly lower incidence rate of upper gastrointestinal bleeding (χ2=4.947 and 5.155, both P＜0.05). At 24 months after discharge, the surgical group had a significantly lower number of patients who had a significant increase in alpha-fetoprotein level than the internal medicine group (χ2=4.648, P=0.031). At 12 months after discharge, the surgical group had a significantly higher incidence rate of portal vein thrombosis than the internal medicine group (χ2=4.395, P=0.036). The surgical group had significant improvements in albumin (F=2.959, P=0.013), cholinesterase (F=11.022, P＜0001), prothrombin time (H=94.100, P＜0.001), and Child-Pugh score (F=3.742, P=0.003) from admission to 12 and 24 months after surgery. ConclusionIn portal hypertension patients with Child-Pugh A/B liver function, LSPD can improve liver function and reduce the incidence rate of upper gastrointestinal bleeding, and the high incidence rate of portal vein thrombosis can be effectively reduced by oral aspirin and rivaroxaban.

Objective: To assess the association of socioeconomic status with the burden of cataract blindness in terms of year lived with disability (YLD) rates and to determine whether ultraviolet radiation (UVR) levels modify the effect of socioeconomic status on this health burden. Methods: National and subnational age-standardized YLD rates associated with cataract-related blindness were derived from the Global Burden of Disease (GBD) study 2017. The human development index (HDI) from the Human Development Report was used as a measure of socioeconomic status. Estimated ground-level UVR exposure was obtained from the Ozone Monitoring Instrument (OMI) dataset of the National Aeronautics and Space Administration (NASA). Results: Across 185 countries, socioeconomic status was inversely associated with the burden of cataract blindness. Countries with a very high HDI had an 84% lower age-standardized YLD rate [95% confidence interval ( Conclusion Long-term high-UVR exposure amplifies the association of poor socioeconomic status with the burden of cataract-related blindness. The findings emphasize the need for strengthening UVR exposure protection interventions in developing countries with high-UVR exposure.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.
