Objective To explore the risk factors of incontinent-associated dermatitis (IAD) in MICU. Methods A retrospective analysis of 141 cases of MICU incontinence in our hospital was done in IAD. The risk factors of IAD were analyzed by single factor and logistic regression analysis. Results The incidence of IAD in MICU fecal incontinence was 43.97%.The risk factors of IAD in MICU incontinence included the amount of defecate,age,body temperature (all P<0.05). Conclusion The incidence of IAD in patients with MICU incontinence is higher.The risk factor for IAD in patients with ICU incontinence are the amount of defecate, age and body temperature.These high-risk factors should be well-considered and relative measures should be done.

To determine the impact of IL-23 knockdown by RNA interference on the development and severity of ovalbumin (OVA)-induced asthmatic inflammation, and the potential mechanisms in mice, the IL-23-specific RNAi-expressing pSRZsi-IL-23p19 plasmid was constructed and inhaled into OVA-sensitized mice before each challenge, as compared with that of control mice treated with alum or budesonide. Inhalation of the pSRZsi-IL-23p19, significantly reduced the levels of OVA-challenge induced IL-23 in the lung tissues by nearly 75%, determined by RT-PCR. In addition, knockdown of IL-23 expression dramatically reduced the numbers of eosinophils and neutrophils in BALF and mitigated inflammation in the lungs of asthmatic mice. Furthermore, knockdown of IL-23 expression significantly decreased the levels of serum IgE, IL-23, IL-17, and IL-4, but not IFNgamma, and its anti-inflammatory effects were similar to or better than that of treatment with budesonide in asthmatic mice. Our data support the notion that IL-23 and associated Th17 responses contribute to the pathogenic process of bronchial asthma. Knockdown of IL-23 by RNAi effectively inhibits asthmatic inflammation, which is associated with mitigating the production of IL-17 and IL-4 in asthmatic mice.

Objective To investigate the expression characteristics of T lymphocyte subsets in peripheral blood of patients with newly diagnosed multiple myeloma(MM),as well as the equilibrium relationship between the ratio of helper T cells 17(Thl7)and CD4+CD25+Foxp3+regulatory T cells(Treg cells),and analyze their clinical significance in the pathogenesis of MM.Methods The proportion of CD3+,CD3+CD4+,CD3+CD8+cells,Th17 cells,Treg cells in peripheral blood and the ratios of CD3+CD4+/CD3+CD8+、Th17/Treg were analyzed between the 30 patients with MM in newly diagnosed and 20 healthy volunteers(control group),then analysis the differences between MM patients and control group.In 30 cases of newly diagnosed MM patients(patient group)and 20 healthy volunteers(control group),total T cells in peripheral blood(CD3+),auxiliary T cells /induced T cells(CD3+CD4+),the inhibitory T cell /cytotoxic T cells(CD3+CD8+),the ratio of(CD3+CD4)/(CD3+CD8+),the percentages of Th17 cells and Treg cell and the ratio of Thl7 and Treg were detected,and the differences between MM patients and control group were compared.Results The ratio of inhibition/cytotoxic T cells(CD3+CD8+)in the patient group was higher than that in the control group(P<0.05).(CD3+CD4+)/(CD3+CD8+)ratio in the patient group was lower than that in the control group(P<0.05);in the patient group,the ratio of Th17 cells in peripheral blood of patients was(5.9 ± 1.9)%,which was increased compared with the control group(4.0 ± 0.9)%(P<0.05);the ratio of Treg cells in the patient group was(1.2 ± 0.3)%,which was decreased com-pared with the control group(2.1 ± 0.4%)(P< 0.05);and the ratio of Th17/Treg cells was significantly higher in the patient group,and the difference was statistically significant(P<0.05).Conclusion Peripheral blood T cell subsets disorder exists in pa-tients with MM,Thl7/Treg cell imbalance caused by the increase of Thl7 cell ratio and the decrease of the ratio of Treg cells,and the imbalance of immune system may play a role in the occurrence and development of MM,and has some guiding value for the prognosis.

OBJECTIVE:
To explore the genetic bases of 3 patients with periventricular nodular heterotopia and epileptic seizure.
METHODS:
The clinical data of three patients presenting with periventricular nodular ectopic with epileptic seizure were analyzed. Whole exome sequencing (WES) was performed on the patients, and Sanger sequencing was used to validate the suspected variants.
RESULTS:
In three female patients, head MRI showed nodular gray matter ectopic in the bilateral ventricle. WES identified the heterozygous c.2720del T(p.Leu907Argfs*39) variant of FLNA gene in case 1 and her mother (case 2), and heterozygous c.1387_1390del GTGC(p.Val463Profs*34) of FLNA gene in case 3. According to the American College of Medical Genetics and Genomics standards and guidelines, the c.2720delT(p.Leu907Argfs*39) and c.1387_1390del GTGC (p.Val463Profs*34) variants of FLNA gene were predicted to be pathogenic (PVS1+PM2+PP1) and likely pathogenic(PVS1+PM2), respectively.
CONCLUSION
The c.2720delT(p.Leu907Argfs*39) and c.1387_1390del GTGC(p.Val463Profs*34) variants of FLNA gene may be the genetic cause of the three patients.

8.mTOR signaling pathway abnormality and epilepsy
Chinese Journal of Neurology 2020;53(10):829-835
Mammalian/mechanistic targets of rapamycin (mTOR) consist in two functional complexes, mTORC1 and mTORC2, which modulate the essential physical process in organism through responding to growth factor, glutamine, neurotransmitter and so on. Overaction of mTOR pathway in the central nervous system is responsible for epilepsy. The article reviews the existing reports to analyze and conclude the phenotypes of the mTOR related epilepsies as well as the likely mechanism, and to provide reference for the diagnosis and treatment of mTOR related epilepsy.

Objective:To investigate the prevalence of dental caries of 4-year-old children in Miyun District of Beijing by international caries detection and assessment system(ICDAS),to detect the caries activity Cariostat value and to analyze the correlation between the Cariostat value and dental caries.Methods:Totally 815 children aged 4 years in 7 kindergartens in Miyun District of Beijing were recrui-ted.The clinical examination of all children was conducted by one examiner using ICDAS.The oral de-birs and plaques were collected by one doctor who recorded the Cariostat scores.The results of clinical examination were compared between genders.At the same time,the prevalence of dental caries,the mean d3-6ft/d3_6fs and d1-6ft/d1-6fs among high Cariostat scores group(2.0-3.0),medium Cariostat scores group(1.5)and low Cariostat scores group(0-1.0)were compared.The distributions of incipi-ent caries in different Cariostat scores groups were compared among children with incipient caries only.Results:All the children had incipient caries,and 78.3%of the children had cavitated caries with ICDAS score of 3 or above.The mean d1-2t scores were 9.76±3.65,the mean d3-6ft scores was 4.64±4.43 and the mean d1-6ft scores were 14.41±3.42.The incipient caries with ICDAS score of 1-2 were widely distributed,accounting for 67.7%of the total numbers of caries.There was no significant diffe-rence in caries prevalence and caries experience between genders(P>0.05).The proportion of children with high Cariostat scores in boys(43.6%)was higher than that in girls(33%)and the difference was statistically significant(P<0.05).With the increase of Cariostat scores,the prevalence of cavitated caries,the mean d3-6ft/d3-6fs and d1-6ft/d,_6fs scores in children was on the increase and the difference among the three groups was statistically significant(P<0.05).For children with incipient caries only,the distribution of incipient caries in different Cariostat scores groups was no significant difference(P>0.05).Conclusion:ICDAS can detect early enamel demineralization of deciduous teeth in children.The prevalence of dental caries among 815 4-year-old children in Miyun District of Beijing is more serious,and incipient caries is widely distributed in children.Cariostat value reflects the status of cavi-tated caries and has no correlation with the distribution of incipient caries.Therefore,the combined ap-plication of ICDAS and Cariostat caries activity detection method is helpful for the detection of incipient caries and screening of caries high-risk children,which has great significance for the comprehensive ma-nagement of caries in children and the formulation of early preventive measures.
