Effect of multi-glycosides of Tripterygium wilfordii on renal injury in diabetic kidney disease rats through NLRP3/caspase-1/GSDMD pyroptosis pathway / 中国中药杂志

This study investigated the effect of multi-glycosides of Tripterygium wilfordii(GTW) on renal injury in diabetic kidney disease(DKD) rats through Nod-like receptor protein 3(NLRP3)/cysteine-aspartic acid protease-1(caspase-1)/gsdermin D(GSDMD) pyroptosis pathway and the mechanism. To be specific, a total of 40 male SD rats were randomized into the normal group(n=8) and modeling group(n=34). In the modeling group, a high-sugar and high-fat diet and one-time intraperitoneal injection of streptozotocin(STZ) were used to induce DKD in rats. After successful modeling, they were randomly classified into model group, valsartan(Diovan) group, and GTW group. Normal group and model group were given normal saline, and the valsartan group and GTW group received(ig) valsartan and GTW, respectively, for 6 weeks. Blood urea nitrogen(BUN), serum creatinine(Scr), alanine ami-notransferase(ALT), albumin(ALB), and 24 hours urinary total protein(24 h-UTP) were determined by biochemical tests. The pathological changes of renal tissue were observed based on hematoxylin and eosin(HE) staining. Serum levels of interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression of pyroptosis pathway-related proteins in renal tissue, and RT-PCR to determine the expression of pyroptosis pathway-related genes in renal tissue. Compared with the normal group, the model group showed high levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), low level of ALB(P<0.01), severe pathological damage to kidney, and high protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01). Compared with the model group, valsartan group and GTW group had low levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), high level of ALB(P<0.01), alleviation of the pathological damage to the kidney, and low protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01 or P<0.05). GTW may inhibit pyroptosis by decreasing the expression of NLRP3/caspase-1/GSDMD in renal tissue, thereby relieving the inflammatory response of DKD rats and the pathological injury of kidney.

Prospective observation of breakthrough cases and analysis of antibody dynamic changes after two doses of varicella / 中华预防医学杂志

Objective: To investigate the breakthrough rate and antibody level of children vaccinated two doses varicella vaccine in Tianjin city, and to compare them with those vaccinated one dose. Methods: A total of 1 112 children who were vaccinated two doses varicella vaccine were selected as the experimental group. According to the same street and township, children who had received only one dose within one year of age difference, and whose first injection time was less than one month from the first dose of varicella vaccine in the experimental group were selected as the control group. A three-year prospective observation was conducted on the incidence of varicella in the two groups. 108 pairs of children in the two groups were selected to collect antivaricella serum in the first to third year. The rate of breakthrough cases, antibody level and antibody positive rate were compared by χ2 test, t-test and variance analysis between and within the two groups in three years. Results: The cumulative breakthrough rate of the experimental group was 0.54%(6/1 112), which was lower than that of the control group 3.96% (44/1 112, χ²=29.544, P<0.001). The GMC level of antibody in the experimental group decreased year by year (F=18.291, P<0.001), and the GMC level in the control group also decreased year by year (F=91.383, P<0.001). There was significant difference in GMC level between the two groups (P<0.001). The difference of antibody positive rate in the experimental group was statistically significant in three years (χ²=11.107, P<0.01), there was significant difference in the positive rate between the first year and third year (P<0.01), there was no significant difference in the positive rate of the control group in three years (χ²=3.351, P>0.05). The positive rate of the experimental group was higher than that of the control group (P<0.001). Conclusion: Two doses varicella vaccine can significantly improve the antibody level and positive rate, but it still shows a downward trend with the extension of time. It is necessary to consider strengthening immunization according to the actual situation.

In vivo fate study of drug nanocarriers: the applications of environment-responsive fluorescent dyes / 药学学报

The in vivo fate is a crucial factor that governs the successful translation of nanoformulations. However, one of the current biggest challenges is with the real-time monitoring of the body of the nanoparticles themselves. Conventional radioactive or fluorescent probes give signals even after they are disassociated from the particle matrix, generating interference to bioimaging and leading to misjudgment of results. Environment-responsive fluorescent dyes are regarded as promising tools due to signal switching in response to the changes in the environment. Currently, there are three categories of dyes in bioimaging of nanoparticles based on Förster resonance energy transfer (FRET), aggregation-induced emission (AIE) and aggregation-caused quenching (ACQ). They have similar characteristics that strong fluorescence is emitted when they are embedded in the matrix of nanocarriers, whereas the fluorescence quenches upon release from the matrix due to dissociation of nanocarriers. The fluorescence switching reflects the existing status of the nanocarriers and therefore helps to interpret the in vivo behaviors. FRET and AIE probes have been widely used in elucidating the interactions between nanoparticles and cell models. However, they show intrinsic defects in studying in vivo fate of nanoparticles. ACQ-based dyes are sensitive to water, a universal factor in the biological environment. Therefore, with the help of bioimaging equipment, the in vivo trafficking process of nanoparticles can be unraveled. This review article tends to provide an overview on the rationale, pros and cons and applications of the three categories of environment-responsive fluorescent dyes in the investigation of the in vivo fate of nanocarriers.

Study on mechanism of Cuscutae Semen flavonoids in improving reproductive damage of Tripterygium Glycosides Tablets in rats based on high-throughput transcriptome sequencing / 中国中药杂志

Tripterygium Glycosides Tablets has good anti-inflammatory and immunomodulatory activities,but its reproductive damage is significant. Previous studies of the research group have found that Cuscutae Semen flavonoids can improve spermatogenic cell damage caused by Tripterygium Glycosides Tablets by regulating spermatogenic cell cycle,apoptosis and related protein expression,but the mechanism of action at the gene level is still unclear. In this study,Illumina high-throughput sequencing platform was applied in transcriptional sequencing of spermatogenic cells of rats after the intervention of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets. Differentially expressed genes were screened out and the GO enrichment and KEGG pathway analysis of differentially expressed genes were conducted to explore the mechanism of Cuscutae Semen flavonoids in improving reproductive injury caused by Tripterygium Glycosides Tablets. The results showed that 794 up-regulated genes and 491 down-regulated genes were screened in Tripterygium Glycosides Tablets group compared with the blank group. Compared with Tripterygium Glycosides Tablets,440 up-regulated genes and 784 down-regulated genes were screened in the Cuscutae Semen flavonoids+Tripterygium Glycosides Tablets group. Among them,the gene closely related to reproductive function is DNMT3 L. Analysis of GO function and KEGG signaling pathway enrichment showed that the above differentially expressed genes were mainly enriched in cell,cell process,catalytic activity,binding,ovarian steroid synthesis,thyroid hormone and other functions and pathways. The thyroid hormone signaling pathway was the common enrichment pathway of the two control groups. In a word,Cuscutae Semen flavonoids has a good treatment effect on male reproductive damage caused by Tripterygium Glycosides Tablets. The mechanism may be closely related to up-regulation of DNMT3 L genes and intervention of thyroid hormone signaling pathway. At the same time,the discovery of many different genes provides valuable information for study on the mechanism of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets compatibility decreasing toxicity and increasing efficiency.

To preliminarily investigate the effect of Tripterygium Glycosides Tablets( TGT) combined with traditional Chinese medicine( TCM) on the fertility and female menstruation on persons who have took during childhood. The children with henoch-schonlein purpura( HSP) or henoch-schonlein purpura nephritis( HSPN) who treated with TGT under 18 years old and now older than 18 years old( including 18 years old) during January 1998 to December 2010 were selected in our research. The content of follow-up visit included marriage,marriage age,fertility and child health; and unmarried female patients were asked whether they had menstrual abnormalities. The data of the unmarried female patients,including age,clinical classification,TCM syndrome type,initial dose and other related factors that may affect menstrual cycle,was analyzed by using binary logistic regression analysis. A total of 195 patients who met the criteria were followed up in this study,and 26 patients married for more than 1 year. Among the 26 married patients,1 HSP patient had no birth planning due to rheumatoid arthritis,and the remaining 25 patients all had given birth or were pregnant. The 169 unmarried patients included 89 female patients. Among the 89 female patients,4 cases refused to tell the menstrual situations,72 cases had normal menstruation( 84. 7%),13 cases had abnormal menstruation( 15. 3%),and there was no case of amenorrhea. Logistic regression analysis results showed that the age,clinical classification,TCM syndrome type and initial dose had no correlation with abnormal menstruation. Our results demonstrated that TGT has no effect on adulthood fertility among patients who took TGT combined with traditional Chinese medicine during childhood.

Comparison of Clinical Features between Noroviral and Rotaviral Gastroenteritis

OBJECTIVE: Rotavirus and norovirus are the most common pathogens causing acute gastroenteritis in children. As the incidence of noroviral gastroenteritis increases, it is becoming more important to identify the clinical features of noroviral infection. We compared the clinical features of noroviral gastroenteritis and rotaviral gastroenteritis. METHODS: This study included 79 children with noroviral and 151 children with rotaviral gastroenteritis, who were admitted to the Soonchunhyang University Gumi Hospital between January 2013 and December 2014. We reviewed their medical records and compared the clinical features of gastroenteritis between the two groups respectively. RESULTS: In those belonging to the norovirus group, the mean age was 29.65 months, which was younger than that of the rotavirus group, at 34.74 months. Patients suffering from noroviral gastroenteritis experienced more vomiting (5.6 episodes/day) than diarrhea (3.5 episodes/day). Vomiting, diarrhea, and fever were all less severe in those suffering from noroviral gastroenteritis. It is commonly noted that patients with noroviral infection have vomiting and diarrhea without fever (55.0%), while those with rotaviral infection present with vomiting, diarrhea, and fever (44.3%). CONCLUSION: Although noroviral gastroenteritis is less severe than rotaviral gastroenteritis, the incidence of noroviral infection is increasing, and the mean age group infected with this virus is getting younger; thus, noroviral infection must be considered in the differential diagnoses in young patients with gastroenteritis.

A case of gastric trichobezoar causing psychiatric problems / 소아과

Trichobezoar is characterized by the accumulation of hair in the gastrointestinal tract and usually occurs in those who have trichotillomania, other psychiatric disorders, or neurologic problems. Trichobezoar typically presents as gastric obstruction, including abdominal pain, vomiting, anorexia, and weight loss. A 9-year-old girl visited our clinic with the complaint of abdominal discomfort and vomiting. A review of her medical history revealed that she had trichophagia since the age of 5, and she felt that her parents had been strict with her. She underwent gastrotomy, during which a large trichobezoar was removed. This case highlights the importance of psychiatric and comprehensive approaches in patients with trichobezoar.
