ObjectiveTo study the changing law of appearance color and physicochemical properties of Angelicae Sinensis Radix Carbonisata（ASRC） during the processing by color space method combined with statistical analysis， so as to provide reference for determining the processing endpoint and evaluating the quality of the decoction pieces. MethodsTaking processing time（4， 8， 12， 16 min） and temperature（180， 200， 220， 240 ℃） as factors， ASRC decoction pieces with different processing degrees were prepared in a completely randomized design. Then， the brightness value（L^*）， red-green value（a^*）， yellow-blue value（b^*）， and total chromaticity value （E^*ab） of the decoction pieces were determined by spectrophotometer， the color difference value（ΔE） was calculated， and the data of colorimetric values were analyzed by discriminant analysis. At the same time， the pH， charcoal adsorption， and contents of tannins， 5-hydroxymethylfurfural（5-HMF）， tryptophan， chlorogenic acid， ferulic acid， senkyunolide I， senkyunolide H and ligustilide of ASRC with different processing degrees were determined by pH meter， ultraviolet and visible spectrophotometry and ultra-high performance liquid chromatography（UPLC）. Principal component analysis（PCA） was used to analyze the data of physicochemical indexes， after determining the processing technology of ASRC， the canonical discriminant function was established to distinguish the decoction pieces with different processing degrees， and leave-one-out cross validation was conducted. Finally， Pearson correlation analysis was used to explore the correlation between various physicochemical indexes and chromaticity values. ResultsWith the prolongation of the processing time， L^*， a^*， b^* and E^*ab all showed a decreasing trend， and the established discriminant model based on color parameters was able to distinguish ASRC with different processing degrees. The pH showed an increasing trend with the prolongation of processing time， and the charcoal adsorption， and the contents of tannins， 5-HMF， and tryptophan all showed an increasing and then decreasing trend. Among them， the charcoal adsorption， contents of tannin and 5-HMF reached their maximum values successively after processing for 8-12 min. While the contents of chlorogenic acid， ferulic acid， senkyunolide I， senkyunolide H and ligustilide decreased with the increase of processing time， with a decrease of 60%-80% at 8 min of processing. Therefore， the optimal processing time should be determined to be 8-12 min. PCA could clearly distinguish ASRC with different processing degrees， while temperature had no significant effect on the processing degree. The 12 batches of process validation results（10 min， 180-240 ℃） showed that except for 3 batches identified as class Ⅱ light charcoal， all other batches were identified as class Ⅲ standard charcoal， and the chromaticity values of each batch of ASRC were within the reference range of class Ⅱ-Ⅲ sample chromaticity values. The correlation analysis showed that the chromaticity values were negatively correlated with pH and charcoal adsorption， and positively correlated with contents of tryptophan， chlorogenic acid， ferulic acid， senkyunolide I， senkyunolide H， and ligustilide. And both pH and charcoal adsorption were negatively correlated with the contents of the above components， but the charcoal adsorption was positively correlated with the content of 5-HMF. ConclusionThe chromaticity values and the contents of various physicochemical indicators of ASRC undergo significant changes with the prolongation of processing time， and there is a general correlation between chromaticity values and various physicochemical indicators. Based on the changes in color and physicochemical indicators， the optimal processing time for ASRC is determined to be 8-12 min. This study reveals the dynamic changes of the relevant indexes in the processing of ASRC， which can provide a reference for the discrimination of the processing degree and the quantitative study of the processing endpoint.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To investigate the correlation between serum vitamin D level and central precocious puberty(CPP)in girls.Methods A total of 103 girls(case group)with central precocious puberty from Ningbo Woman and Children's Hospital and 53 healthy girls(control group)from health check-ups in Ningbo Women and Children's Hospital were collected as subjects.The serum levels of 25-hydroxyvitamin D3[25(OH)D3]in the two groups were detected by chemiluminescence method.The weight and height of girls in the case group were measured.The serum levels of follicle-stimulating hormone(FSH)and its peak value,luteinizing hormone(LH)and its peak value,estradiol(E2),prolactin(PRL),human chorionic gonadotropin(HCG)and thyroid function were measured by radioimmunoassay.The peak value of LH/FSH was calculated.B ultrasound examination of uterine adnexa was completed to calculate uterine volume and bilateral ovarian volume.According to the results of serum 25-(OH)D3,girls in the case group were divided into normal vitamin D group and vitamin D deficiency group,and the differences of hormone levels,uterine and ovarian development between the two groups were compared.Results The serum level of 25-(OH)D3 in case group was lower than that in control group,and the vitamin D deficiency rate in case group was higher than that in control group,with statistical significance(P<0.05).The age of breast nodules in vitamin D deficiency group was lower than that in vitamin D normal group(P<0.05).There were no significant differences in body weight,height,body mass index(BMI),uterine volume and left ovarian volume between vitamin D normal group and vitamin D deficiency group(P>0.05),and the right ovarian volume in vitamin D deficiency group was significantly higher than that in vitamin D normal group(P<0.05).There were no significant differences in serum levels of FSH,LH,PRL,HCG,peak value of FSH and thyroid function between normal and deficient groups(P>0.05).The levels of E2,LH and LH/FSH in vitamin D deficiency group were significantly higher than those in vitamin D normal group(P<0.05);25-(OH)D3 was negatively correlated with LH/FSH peak(r=-0.197,P<0.05),but was not significantly correlated with thyroid function,FSH,LH,PRL,E2,HCG,FSH and LH peak(P>0.05).Conclusion Vitamin D deficiency is associated with central precocious puberty in girls.Vitamin D deficiency may lead to early onset of precocious puberty.Vitamin D deficiency may affect the hypothalamic-pituitary-gonadal axis function,resulting in changes in reproductive hormone indexes and consequent increase in ovarian volume in girls.

Objective:To explore the status quo and influencing factors of self-management behavior in high-risk stroke patients, so as to provide a basis for improving their self-management behavior.Methods:From March to June 2023, convenience sampling was used to select 395 high-risk stroke patients admitted to the First Affiliated Hospital of Naval Medical University as the study subject. A survey was conducted on patients using the General Information Questionnaire, Self-management Behavior Scale for High-risk Stroke Patients, and Cerebral Apoplexy Knowledge Questionnaire. Pearson correlation was used to analyze the correlation between self-management behavior and stroke knowledge. A total of 395 questionnaires were distributed, and unqualified questionnaires (such as regular or repetitive responses, conflicting options before and after) were excluded. Finally, 387 valid questionnaires were collected, with an effective response rate of 97.97%.Results:The score of the Self-management Behavior Scale for High-risk Stroke Patients for 387 high-risk stroke patients was (137.60±25.47), with a score indicator of 62.53%, which was at a moderate level. The score of the Cerebral Apoplexy Knowledge Questionnaire was (19.26±10.19), which was at a low level. The random forest algorithm showed that the importance order of influencing factors was stroke knowledge, number of ways to obtain health information, educational level, number of risk factors, frequency of physical examinations, medical insurance, age, work situation, and gender. The Lasso regression indicated that there were four influencing factors corresponding to the minimum error. The top four factors in importance were included in multiple linear regression, and the results showed that educational level, number of risk factors, number of ways to obtain health information, and stroke knowledge were the influencing factors of self-management behavior in high-risk stroke patients ( P<0.05) . Conclusions:The self-management behavior of high-risk stroke patients was at a moderate level. Medical and nursing staff should strengthen stroke knowledge education, provide personalized education for different risk factors, and improve the self-management of the target population to reduce the incidence of stroke.

【Objective】 To investigate the effects of the loss of exon 1 of TFE3 on nuclear localization of chimeric TFE3 protein in TFE3 translocation renal cell carcinoma (TFE3 tRCC). 【Methods】 The localization of TFE3 protein in TFE3 tRCC and clear cell renal cell carcinoma (ccRCC) were detected with immunochemistry. The exon retention of TFE3 gene in TFE3 tRCC was analyzed in databases and literatures. The plasmids containing TFE3 full-length and different-length of TFE3 exons which were constructed to pCDH-MCS-EGFP-Puro were transfected into HEK293T using Lipo Fiter^TM. The localization of EGFP protein in HEK293T cells were detected with confocal microscopy. The localization of TFE3 protein and truncated TFE3 protein were detected with Western blotting. The mRNA expression of the downstream genes of TFE3 protein were detected with q-PCR. 【Results】 Strong nuclear signal of TFE3 protein was observed in TFE3 tRCC, whereas TFE3 protein in ccRCC was mainly localized in cytoplasm. The results of fluorescence imaging and Western blotting showed that TFE3 full-length protein was expressed both in nucleus and cytoplasm, and the expression of truncated TFE3 protein was mainly localized in nucleus. The q-PCR analysis demonstrated that the deletion of exon 1 in TFE3 gene led to a higher transcriptional level of targeted genes of TFE3 protein. 【Conclusion】 The loss of exon 1 in TFE3 played a critical role in preventing TFE3 protein from entering the nucleus. In TFE3 tRCC, the loss of exon 1 in TFE3 gene leads to the nuclear localization of TFE3 fusion protein and activation of its downstream target genes. This mechanism promises to uncover the occurrence and development of TFE3 tRCC.

Objective To explore the influence factors of the metabolic syndrome in the continuous ambu-latory peritoneal peptide(CAPD)patients. Methods A total of 104 CAPD in the PD center of the First and the Second Affiliated Hospital of Guangxi Medical University from June 2014 to June 2016 were enrolled in this study. Patients were divided into the metabolic syndrome(MS)and the non-metabolic syndrome(non-MS)group. The clinical data of patients with MS and non-MS was compared,and the influence factors of the MS in PD patients were analyzed. Results Twelve patients were diagnosed as metabolic syndrome. Significant differences in age, urine volume,serum phosphorus(P)and uric acid(UA)were observed between group MS and non-MS(P<0.05). Twenty people were overweight,with the prevalence rate of 19.2%. Compared with the normal and overweight group,age,high density lipoprotein(HDL),P and serum iron were statistically significant(P < 0.05). Thirty-one people were diagnosed as dyslipidemia,with the prevalence rate of 29.8%. Compared with the normal group, albumin,UA,BMI and D/P were statistically significant in the dyslipidemia group(P < 0.05). Ten patients were diagnosed as hyperglycemia,with the prevalence rate of 9.6 %. Significant differences in hemoglobin and the dia-stolic blood pressure(DBP)were found between the hyperglycemia group and the normal group(P < 0.05). Age and P were shown as independent risk factors for PD patients with MS(P<0.05,respectively).Conclusion The peritoneal dialysis patients were more likely to have metabolic syndrome than the normal population.Age and serum phosphorus are the factors influencing the occurrence of MS in peritoneal dialysis patients.
