Objective:To analyze and compare the fishy components in raw, stir-fried, liquorice-processed, vinegar-processed and wine-processed products of Pheretima aspergillum, and explore the material basis and processing principle of fishy smell of P. aspergillum. Method:Heracles Ⅱ ultra-fasted gas chromatography electronic nose technology combined with chemometrics was used for the overall analysis of volatile components in raw P. aspergillum and its processed products. Headspace gas chromatography-mass spectrometry (HS-GC-MS) was used to analyze and identify the volatile compositions in the raw products and processed products. Gas chromatographic conditions were as following：temperature program (initial temperature at 60 ℃, kept for 5 min, up to 120 ℃ with the heating rate of 3 ℃·min-1, and then up to 230 ℃ with the heating rate of 10 ℃·min-1 and finished), the inlet temperature at 280 ℃, high purity helium as the carrier gas, the flow rate of 1.0 mL·min-1, the split ratio of 20∶1. Mass spectrum conditions were as following：electron impact ionization (EI), electron collision energy of 70 eV, ion source temperature of 230 ℃, quadrupole temperature at 150 ℃, scanning range of m/z 50-550. The relative content of each component was calculated by peak area normalization. Result:Principal component analysis (PCA) and discriminant factor analysis (DFA) of the electronic nose showed that the raw products and its processed products could be clearly distinguished from each other. Among them, the difference between raw products and stir-fried, liquorice-processed products was small, but the difference between raw products and vinegar-processed, wine-processed products was large. A total of 25, 27, 22, 26 and 33 components were respectively identified from raw, stir-fried, liquorice-processed, vinegar-processed and wine-processed products of P. aspergillum, there were 13 common components in these products, including 4 aldehydes (isovaleraldehyde, 2-methylbutyraldehyde, hexanal, benzaldehyde), 2 ketones (2-heptanone, 2-tridecanone), 1 carboxylic acid (lauric acid), 4 heterocyclic compounds (2-methylpyrazine, 2,5-dimethyl pyrazine, 2-pentylfuran, 2-ethyl-6-methyl pyrazine), 1 amine (trimethylamine) and 1 alcohol (1-octen-3-ol). Conclusion:The odorous components in the raw products are mainly derived from aldehydes (isovaleraldehyde, 2-methylbutyraldehyde, isobutyraldehyde, 2-ethylhexanal, hexanal) and amines (trimethylamine). Odorous components of P. aspergillum can be reduced effectively by stir-fried and liquorice, vinegar, wine processing, while flavoring substances can be increased by wine processing to cover its ugly odor. This paper can provide scientific basis for the deodorization of P. aspergillum by processing, and also provide reference for the analysis and correction of ugly odor of other animal medicines.

Effect of Dihydrotestosterone on CostimulatoryMolecules in a Mouse Model of Graves' Disease / 中国医学科学杂志(英文版)

Objective Graves' disease is the most common autoimmune thyroid disease and its prevalence and clinical manifestations are disparate between females and males. Costimulatory molecules play an essential role in regulating autoimmune responses. The objective of this study was to determine if expression of inhibitory molecules was correlated with treatment by dihydrotestosterone (DHT) in an BALB/c mouse model of experimental autoimmune Graves' disease.Methods Female BALB/c mice were immunized three times with thyroid stimulating hormone receptor A-subunit encoded by adenovirus to establish a Graves' disease model. Three different doses of DHT or a matching placebo were administered by implantation of slow-release pellets a week before the first immunization. Four weeks after the third immunization, the mice were euthanatized, and then the spleen and thymus were removed. Total thyroxine and free thyroxine levels in serum of mice were detected using a radioimmunoassay kit. Real-time polymerase chain reaction was performed to estimate the expression of costimulatory molecules in lymphocytes from the spleen and thymus. Flow cytometry was used to analyze the percentage of CD4 T cells in splenic lymphocytes. Quantitative data were compared with unpaired -tests. Correlation between two variables was analyzed using Analysis of Variance.Results Treatment with DHT can dramatically reduce total thyroxine and free thyroxine levels. Higher expression of programmed death-1 was found in the spleen of Graves' disease mice receiving 5 mg of DHT treatment (0.635±0.296 . 0.327±0.212; =2.714, =0.014), similarly, T-cell immunoglobulin domain and mucin domain 3 (TIM-3) in both the spleen (1.004±0.338 . 0.646±0.314; =2.205, =0.022) and the thymus (0.263±0.127 . 0.120±0.076; =3.221, =0.004) also increased after 5 mg of DHT treatment compared with the parallel placebo model mice. Moreover, the percentage of CD4 T cells declined in the splenic lymphocytes of Graves' disease mice treated with 5 mg of DHT (19.90%±3.985% . 24.05%±2.587%; =2.804, =0.012). A significant negative association was observed between expression of TIM-3 in the spleen and serum levels of total thyroxine (=-0.7106, =0.014) as well as free thyroxine (=-0.6542, =0.029).Conclusion This study demonstrates that DHT can ameliorate experimental autoimmune Graves' disease, which may occur by up-regulating expression of programmed death-1 and TIM-3 and inhibiting development of CD4 T cells.

Mechanisms of triiodothyronine on maturation and differentiation of B cells / 医学研究生学报

Objective Higher expression of B-cell activating factor (BAFF) in patients with Graves' disease can activate B cells and increase proportion of plasma cells. However, the mechanism is still unclear. This study aims to investigate the effects of T3 on the BAFF level and plasma cell ratio in bone marrow, spleen and peripheral blood of mice, and to explore the mechanism of T3 in affecting the mature and differentiation of B cells. Methods 80 C57BL/6J mice were randomly divided into control group and T3 group, and were given isotonic saline or T3 5/10μg once a day for 6 weeks, respectively. The levels of T3 in peripheral blood of each group were measured with ELISA. Flow cytometry was used to detect the proportion of B220+CD138+ plasma cells and IgM, IgG and IgD expression of B cells in the spleen, bone marrow and peripheral blood. Immunohistochemistry, Western blot and PCR were performed to determine the expression of BAFF in spleen and thyroid. ELISA was used to determine the expression of BAFF in peripheral blood. Results Compared with control group, the levels of T3 in peripheral blood, diet and drinking water in the T3 group were significantly increased after 6 weeks T3 intervention. The mRNA and protein expression of BAFF in spleen mononuclear cells of T3 group (2.03±0.52, 0.50±0.03) were higher than those in control group (1.06±0.19, 0.05±0.01) (P<0.01). HE staining showed that the white medulla in the spleen of the T3 group increased and merged. Flow cytometry indicated that the proportion of spleen plasma cells and antibody expression of B cells in T3 group [(3.92±1.55)%, (75.76±8.88)%] increased compared with control group [(2.43±1.18)%, (65.26±8.38)%] (P<0.05); Proportion of bone marrow plasma cells [(8.48±3.62)%] and antibody expression [(40.63±18.96)%] in T3 group were significantly increased compared with control group [(4.96±3.11)%, (22.89±7.32)%](P<0.05); Peripheral plasma cell ratio [(8.56±4.27)%] and antibody expression [(76.15±9.44)%] were lower than those in control group [(14.70±4.76)%, (84.20±3.98)%](P<0.05); Compared with control group [(5.98±0.78) pg/mL], the BAFF level in peripheral blood increased [(7.61±1.72) pg/mL] (P<0.01). Immunohistochemistry showed that the expression of BAFF increased in mononuclear cells of thyroid of the T3 group. Conclusion T3 could activate BAFF expression in bone marrow, spleen, peripheral blood and thyroid mononuclear cells, and induce differentiation of bone marrow and spleen B cells, thus causing pathological changes in thyroid tissue. Such mechanisms might play an important role in the pathogenesis of thyroid autoimmune diseases.

Effects of thyroid hormones on cardiac function in mice by inducing expression of B-cell activating factor in cardiomyocytes / 医学研究生学报

Objective　High levels of triiodothyronine (T3) can lead to hyperthyroid heart disease, but its mechanism is unclear. This study aims to investigate the effects of T3 on the expression of B-cell activating factor (BAFF) in cardiomyocytes and to explore its possible role in the pathogenesis of hyperthyroid heart disease.　Methods　Sixty healthy C57BL/6J mice were selected and randomly divided into two groups: the experimental group and the control group. The experimental group received intraperitoneal injection of T3 at 5 μg/ml, one time/d, for 42 consecutive days. The concentrations of serum T3 and tetraiodothyronine (T4) were detected by radioimmunoassay; ELISA was used to determine BAFF expression in peripheral blood, and the cardiac index and the transverse diameter of myocardial cells in each group were determined. Immunohistochemistry and Western blot were used to detect the expression of BAFF protein in myocardium and of myocardial tumor necrosis factor-α (TNF-α) protein; the expression of BAFF mRNA in myocardium was detected by Real-Time PCR; flow cytometry (FCM) was used to detect changes in the proportion of B-cells in the heart.　Results　Compared with the control group, the serum T3 concentration, cardiac index, BAFF and myocardial cell transverse diameter of the experimental group significantly increased (P<0.05), and the T4 concentration decreased (P<0.05). Under the light microscope, the cardiomyocytes of the control group were normal, while those of the experimental group were hypertrophied and disordered in structure. Compared with the control group (0.765±0.164), BAFF protein expression significantly increased in the experimental group (1.865±0.290) (P<0.05). Compared with the control group (0.537±0.089), the expression of TNF-α protein significantly increased in the experimental group (0.737±0.065) (P<0.05). Correlation analysis of T3 with BAFF gene expression in cardiomyocytes and BAFF level in peripheral blood showed that T3 was positively correlated with both the former with a correlation coefficient of 0.637 (P<0.01) and the latter with 0.778 (P<0.01). For FCM, compared with the control group [(12.40±1.09)%], the proportion of myocardial B-cells increased in the experimental group [(16.12±0.631)%] (P<0.05).　Conclusion　High concentration of T3 can promote the expression of BAFF in myocardial cells and lead to the activation of B-cells, thus increasing the inflammatory response and leading to myocardial hypertrophy.

Enuresis alarm therapy for preschool children with primary monosymptomatic nocturnal enuresis: A report of 95 cases / 中国实用儿科杂志

OBJECTIVE: To explore the effectiveness of enuresis alarm therapy on preschool children with primary monosymptomaticnocturnal enuresis(PMNE). METHODS: Totally 95 PMNE preschool children aged 3.5 to 6 years admitted between January 2017 and July 2018 to Department of Nephrology,Affiliated Children's Hospital of Capital Institute of Pediatrics,were randomly divided into two groups:alarm group(53 cases)and control group(42 cases). The alarm group was managed by enuresis alarm therapy,while the control group received basic treatment. Treatment ceased after 12 weeks of training or when the cases achieved 14 consecutive dry nights(meaning successful treatment). The relapse cases were recorded 1 month after stopping treatment. The alarmtherapy was performed again in the relapse cases for another course. RESULTS: Seven cases(13.2%)discontinued intervention in the alarm group. The response of the alarm therapy in the remaining 46 patients was as follows:full response(FR)in 29 cases(63.0%),partial response(PR)in 7 cases(15.2%),no response(NR)in 10 cases(21.7%). A total of 25 patients achieved 14 consecutive dry nights in FR cases. Successful treatment requires a minimum course of treatment for 42 days. Relapse occurred in 11 cases within the first 1 month after stopping treatment,and 8 relapse patients responded to another course of alarm therapy. Three cases(7.1%)lost to follow-up in the control group. The response of the control group in the remaining 39 patients was as follows:FR in 0 case,PR in 17 cases(43.6%)and NR in 22 cases(56.4%). No cases achieved successful treatment in the control group. The full response rate was significantly different between two groups(Fisher's exact test χ~2=55.10,P=0.00). Half(5 cases)of NR patients were less than 4 years old,while in the FR+PR patients,the percentage of children under 4 years old was only 8.3%(3 cases)in alarm therapy group(Pearson chi-square test,χ~2=9.457,P=0.007). No severe adverse events occurred in all cases. CONCLUSION: Enuresis alarm therapy is a safe and effective way to treat PMNE preschool children. The enuresis alarm provided gradual effects and require more than 1 month in achieving successful effect. The appropriate age for alarm treatment is over four years old.

Comparison of chemical constituents between Cyathula offinalis and adulterant and their admixture by HPLC characteristic chromatogram fingerprint combined with chemometrics / 中国中药杂志

Cyathula capitate is the main adulterant of C.offinalis. According to the literature reported, there are obvious differences in properties, taste and pharmacological activity between C. capitate and C.offinalis. Therefore, C. capitate can only be used as a local conventional medicine and can't be a substitute for C. offinalis. Since the appearance of C.capitata is very similar to the C.offinalis and the content of cyasterone also can reach the limit of the current pharmacopoeia standard, the C.capitata is mostly sold in the form of impersonation oradmixture, which seriously affected the safety of the clinical medication and the development of the genuine crude drugs. In view of this, HPLC characteristic fingerprint was used to reveal the difference of multi-ingredients of C. offinalis, C. capitata and their admixture. According to the HPLC chromatogram of C.offinalis, C. capitata. and their admixture, 65 different components were obtained to set up a peak area data matrix of 26×65, which was applied to perform the characteristic peak difference analysis, similarity analysis, hierarchical clustering analysis HCA and principal component analysis (PCA). Characteristic peak difference analysis showed that the characteristic peaks of C. capitata and their admixture are more and higher respond than those of C. offinalis. The 9 characteristic peaks were used to distinguish C. capitata, 2 of which were used to distinguish C. offinalis mixed with 5% C. capitata. UV spectra of 9 characteristic peaks are mostly similar to the end absorption spectra of saponins, indicating that C. capitata may contain a large amount of saponins. By the reference fingerprint of C.offinalis established, the similarity analysis showed that the similarity degree of C. offinalis are higher than 0.942, while the similarity degree of C. capitata, C.offinalis mixed with 5% C. capitata are less than 0.383 and 0.399. C.offinalis, C. capitata, C.offinalis mixed with 5% C. capitata could be obviously divided into 3 classes by HCA and PCA. These results showed that there are obvious difference in the chemical composition of C. offinalis, C. capitata and their admixture, which could provide evidence for their identification.

Expression levels of steroids synthase such as Star, Cyp11a1, Cyp21a1, Hsd3b2, Cyp11b1, Cyp11b2, Cyp17a1, and Hsd17b3 mRNA were detected by Real time quantitative PCR (RT-qPCR).</p><p><b>RESULTS</b>Y1 cell proliferation was obviously inhibited by 100 and 200 micromol/L Ost, and its inhibitory effect was more significant in 0.1% serum medium. Compared with the negative control group, gene expressions of Star, Cyp11a1 , Cyp21a1, Hsd3b2, Cyp11b1, Cyp17a1, and Hsd17b3 were significantly enhanced in the posi- tive control group (P < 0.05). Y1 cell corticosterone levels significantly increased in 50 micromol/L Ost treatment group after 24-and 48-h intervention (P < 0.05). Contents of corticosterone increased more obviously in 25 and 50 +/- mol/L Ost treatment groups after 48-h intervention, as compared with 24-h intervention (P < 0.01). After 24-h intervention, expression levels of Star, Cyp21a1, and Hsd3b2 genes were significantly up-regulated in 25 and 50 lLmol/L Ost groups (P < 0.05). Star gene expression was further enhanced after 48-h intervention (P < 0.05). However, Ost showed no effect on Cyp11a1 (P > 0.05). Additionally, gene expressions of Cyp11b1 and Cyp17a1 were significantly enhanced by 10, 25, and 50 pLmolIL Ost after treatment for 24 and 48 h (P < 0.05). Ost showed no obvious effect on Cyp11b2 and Hsd17b3 expressions.</p><p><b>CONCLUSION</b>Ost could regulate adrenal cortex function and promote corticosterone synthesis and secretion through strengthening gene expressions of steroidogenic enzymes.</p>

Study progress of pathogenesis of primary nocturnal enuresis in children / 中华实用儿科临床杂志

Primary nocturnal enuresis is a common childhood disorder,increasingly seen as part of a heterogeneous phenomenon.Nocturnal polyuria,overactive bladder,high arousal thresholds and genetics are in various combinations,central to enuresis pathogenesis.Psychiatric problems also play important roles in the pathogenesis of primary nocturnal enuresis.There are still underlying pathophysiological mechanisms to be discussed and researched.

Clinical characteristics and prognosis of congenital solitary kidney combined with renal damage in children / 中华实用儿科临床杂志

Objective To analyze the clinical characteristics and the prognosis of congenital solitary kidney in 9 children and to find the causes of renal impairment and factors associated with the prognosis.Methods The clinical data of 9 children with congenital solitary kidney in Beijing Children's Hospital Affiliated to Capital Medical University were analyzed,retrospectively.Data of long-term prognosis were collected through follow-up study.Results Five girls and 4 boys were involved in the analysis,ranging from 3.9 to 16.0 years old.The mean inpatient age was 9.9 yearsold.The patients showed different symptoms in renal impairment of solitary kidney:9 patients with proteinuria,and 3 of them had manifestation of asymptomatic proteinuria,in the early stage,3 with abnormalities of renal functions,3 diagnosed as nephrotic syndrome,and 2 with purpuric nephropathy.In the ultrasound examination of renal morphology,4 cases had normal echo image,5 cases had enhanced echo image and 2 patients had developmental malformation of the solitary kidney.The patients received follow-up visits within 1.5 to 7.0 years.The disease deteriorated into chronic kidney disease (stage 4-5) in 3 patients,1 patient underwent dialysis treatment,1 patient developed consistent and progressive proteinuria;whereas proteinuria disappeared in 4 patients and renal functions remained normal.Conclusions The renal impairment of congenital solitary kidney is mainly manifested as proteinuria,without symptoms in the early stage.In some patients,renal impairment can deteriorate into abnormalities of renal function or renal failure.The early ultrasound screening of the urinary system is recommended.Long-term follow-up should be conducted in children of solitary kidney to find early renal impairment and take appropriate treatment for them,thus to delay the occurrence and deterioration of renal impairment.
