Objective To explore the cognitive function of the theory of mind(TOM) in early-onset schizophrenia from faux pas recognition and belief understanding dimensions.Methods 41 early-onset schizophrenias (EOS) and 40 normal adolescents were interviewed by the Chinese version of faux pas recognition task and theory of mind picture-sequencing task(ToM-PST),then early-onset schizophrenias cognitive features were analyzed.Results ①In faux pas recognition task,compared with healthy subjects,EOS showed significantly less total scores (16.11±6.34 vs 20.86±7.79,P＜0.05)and subscores of understanding faux pas questions (9.88±4.11 vs 13.27± 6.07,P＜0.05).In faux pas recognition scores(6.72±2.60vs 7.58±2.20) and control questions(9.83±0.44vs 9.97± 0.16) had no statistically significant difference (P＞0.05).②In ToM-PST task,early-onset schizophrenic patients also had significantly less total score(17.29±3.38 vs 21.48± 1.73,P＜0.01),subscores of understanding first order belief,first order error belief,second order belief,second order error belief,third order error belief,sense of reality,reciprocity,fraud,detecting fraud compared to normal controls had significant difference (all P＜ 0.05 or 0.01).③ The correlation between clinical course time and PANSS score and its subscores of the theory of mind picture-sequencing and faux pas task was non-significant(P＞0.05)except the subscores of understanding the first order belief (P＜0.01).Conclusion The theory of mind is apparent damage in early onset schizophrenia and non-significant correlation is found with psychiatric symptoms.

Objective:To explore the application of failure mode and effects analysis (FMEA) in low-energy X-ray intraoperative radiotherapy (IORT), analyze its potential risks in IORT, and preliminarily explore the feasibility of FMEA in optimizing IORT management and reducing the occurrence of potential risks.Methods:An FMEA working group was established by the IORT team (1 radiologist, 1 radiology physicist, 2 surgeons, and 2 nurses) to apply the FMEA methodology to conduct a systematic risk assessment. The process modules were established, the potential failure modes and causes for each module were analyzed, the severity (SR), frequency of occurrence (OR) and likelihood of detection (DR) of failure modes were scored and the risk priority number (RPN) was calculated: RPN= SR × OR × DR. The possible errors and potential clinical impact of each part of the radiotherapy process were prospectively analyzed and understood, the causes and current measures were analyzed for each failure mode and preventive measures were proposed and risk management measures were taken accordingly.Results:The IORT process was divided into 8 modules with 14 failure modes. The highest OR value was unsatisfactory target area confirmation (7 points), the highest SR value was equipment failure to discharge the beam (10 points), the highest DR value was wrong key entry after dose calculation (7 points), the highest RPN values were unsatisfactory target area confirmation (210 points) and ineffective protection of endangered organs (180 points). Weaknesses were corrected according to priorities, workflows were optimized and more effective management methods were developed.Conclusion:FMEA is an effective method of IORT management and contributes to reducing the occurrence of potential risks.

【Objective】 To explore the difference of total protein (TP) content, coagulation factor VIII (FⅧ) activity and Fib content in different common plasma products, and to further provide basis for the establishment and refinement of relevant quality standards of common plasma products. 【Methods】 Samples involved in the experiment included frozen plasma and cryoprecipitated frozen plasma derived from whole blood and eukocyte-depleted whole blood. The TP content determination was carried out by biuret method. The FⅧ activity (FⅧ: C) and Fib content were determined by coagulation method. 【Results】 The TP content( g/L) in frozen plasma and cryoprecipitated frozen plasma derived from whole blood and eukocyte-depleted whole blood were 59.64±4.78 vs 58.09±4.1 vs 52.20±3.57 vs 51.89±1.50, respectively, and the FⅧ: C( %) were 109.63±43.38 vs 27.06±7.09 vs 71.83±21.64 vs 21.66±3.86,, and the Fib content (g/L) were 2.19±0.39 vs 1.30±0.24 vs 2.04±0.37 vs1.22±0.15, respectively. There was a significant difference in TP content between other common plasma products (P<0.05) while similar between frozen plasma and cryoprecipitated frozen plasma derived from eukocyte-depleted whole blood (P>0.05). There was significant difference in FⅧ: C among four common plasma products (P<0.05). The Fib content of cryoprecipitated frozen plasma was significantly lower than that of frozen blood, and there was no significant difference in Fib content among other common plasma products (P>0.05). 【Conclusion】 The TP content and FⅧ: C of common plasma products are closely related to the initial blood and preparation process. It is suggested that the quality standard of common plasma products should be further refined, and the establishment of cryoprecipitated frozen plasma relevant quality standard and clinical indications should be considered.

【Objective】 To establish the internal quality control standard of leukocyte-depleted suspended red blood cell volume in our center, so as to guide the preparation of components, strengthen the internal quality control and improve the quality of blood preparations. 【Methods】 A total of 1 523 bags of whole blood collected using two manufacturers′ leukocyte-depleted blood bags from March to August 2023 at our center were extracted. The blood before and after filtration were weighed, and the volume of whole blood collected, the volume of filtration loss and the product volume based on the formula and measured specific gravity were calculated. According to the data distribution characteristics, the reference range of leukocyte-depleted suspended red blood cell volume was determined, and the differences of whole blood collection volume, filtration loss capacity and product capacity between the two manufacturers were analyzed. The quality control data of leukocyte-depleted red blood cells over the past year with the difference between another 100 bags of these cells and the reference interval were compared, and the effectiveness of reference interval was validated. 【Results】 The median whole blood collection volume in the sample size was 402.0 mL, with a median filtration loss of 42.4 mL, and an average volume of leukocyte-depleted suspended red blood cells at 322.5 mL. The whole blood collection volume (A: median 404.4 mL; B: median 397.7 mL, P<0.01) and the volume of leukocyte-depleted suspended red blood cell products (A: mean 331.4 mL; B: mean 312.0 mL, P<0.01) using manufacturer A′s leukocyte-depleted blood bag were both higher, with a lower filtration loss capacity (A: median 39.5 mL; B: median 46.6 mL, P<0.01). The standard deviation of the volume of leukocyte-depleted suspended red blood cell was 19.6, and the reference interval was 284.1-360.9 mL.

Few medications are available for meeting the increasing disease burden of nonalcoholic fatty liver disease (NAFLD) and its progressive stage, nonalcoholic steatohepatitis (NASH). Traditional herbal medicines (THM) have been used for centuries to treat indigenous people with various symptoms but without clarified modern-defined disease types and mechanisms. In modern times, NAFLD was defined as a common chronic disease leading to more studies to understand NAFLD/NASH pathology and progression. THM have garnered increased attention for providing therapeutic candidates for treating NAFLD. In this review, a new model called "multiple organs-multiple hits" is proposed to explain mechanisms of NASH progression. Against this proposed model, the effects and mechanisms of the frequently-studied THM-yielded single anti-NAFLD drug candidates and multiple herb medicines are reviewed, among which silymarin and berberine are already under U.S. FDA-sanctioned phase 4 clinical studies. Furthermore, experimental designs for anti-NAFLD drug discovery from THM in treating NAFLD are discussed. The opportunities and challenges of reverse pharmacology and reverse pharmacokinetic concepts-guided strategies for THM modernization and its global recognition to treat NAFLD are highlighted. Increasing mechanistic evidence is being generated to support the beneficial role of THM in treating NAFLD and anti-NAFLD drug discovery.

BACKGROUND: Many studies have investigated heavy metal exposure could increase the occurrence of congenital heart defects (CHDs). However, there are limited data regarding the relationship between cobalt exposure and CHD occurrence in offspring. The aim of this study was to analyze the association between cobalt exposure in mothers and the risk of CHDs in offspring. MATERIALS AND METHODS: In order to explore the association between cobalt exposure and occurrence of congenital heart defect (CHD), a case-control study with 490 controls and 399 cases with CHDs in China were developed. The concentrations of cobalt in hair of pregnant woman and fetal placental tissue were measured and processed by a logistic regression analysis to explore the relationship between cobalt exposure and risk of CHDs. RESULTS: The median concentration of hair cobalt in the control and case group was 0.023 ng/mg and 0.033 ng/mg (aOR, 1.837; 95% CI, 1.468-2.299; P < 0.001), respectively. And the median (5-95% range) fetal placental cobalt concentrations were 19.350 ng/g and 42.500 ng/g (aOR, 2.924; 95% CI, 2.211-3.868; P < 0.001) in the control and case groups, respectively. Significant differences in the middle level of cobalt in hair were found in the different CHD subtypes, including septal defects, conotruncal defects, right ventricular outflow tract obstruction, and left ventricular outflow tract obstruction (P < 0.001). Dramatically, different cobalt concentrations in fetal placental tissue were found in all subtypes of cases with CHDs (P < 0.01). CONCLUSIONS The finding suggested that the occurrence of CHDs may be associated with cobalt exposure.
