Objective:To obsere the clinical efficacy of Hall technology in the treatment of primary molar caries in children with au-tism.Methods:80 children aged 4-8 years with primary molar caries,40 normal children and 40 children with autism,with a total of 153 primary molars.The normal and the autism children were respectively divided into 2 groups(n=20)randomly.The normal children were grouped into resin filling(CR)of 38 teeth and Hall technology group(CH)of 39 teeth,the autistic children were grouped into resin filling(AR)of 37 teeth and Hall technology group(AH)of 38 teeth.Corresponding treatment was given to the pa-tients in the groups.The duration of oral treatment time,Frankl scores,Houpt scores and parental satisfaction scoves were compaired among groups.The patients were followed up for 6,12,18 and 24 months and the treatment outcomes were compared among groups.Results:There was no statistically difference between CH group and AH group in terms of operating time,compliance,Houpt score and follow-up effects(P＞0.05).The satisfaction of parents in the AR group was the lowest(P＜0.05).Hall technology treatment re-mained effective rate was higher than resin filling at the 24 month follow-up(P＜0.05).Conclusion:Hall technology is more effective than traditional resin filling in the treatment of primary molars caries in children with autism.

Extracorporeal membrane oxygenation(ECMO),an effective extracorporeal circulation support system,holds significant importance in the treatment of severe cardiovascular and pulmonary diseases.Effective fixation of ECMO catheters can prevent adverse events such as displacement and accidental extubation,thereby ensuring the effectiveness and continuity of ECMO treatment.At present,various tools such as transparent dressings,surgical dressings,and bandages are commonly used in clinical practice.However,there are problems such as insufficient fixation,unattractive and tidy appearance,and inconvenient replacement.There is still a lack of specific and effective dressings to fix ECMO catheters.Therefore,the medical staff from department of critical care medical of Hospital of Chengdu University of Traditional Chinese Medicine designed ECMO dressing,and obtained the National Utility Model Patent of China(patent number:ZL 202120543021.3),which includes 3 parts:upper dressing,middle dressing,and lower dressing with weak connections in sequence.The top surface of the upper dressing is the upper dressing layer,which is marked with a first scale.The middle part of the bottom surface of the upper dressing layer is fixed with a gauze layer.The top surface of the middle dressing is the middle dressing layer,and the bottom surface of the middle dressing layer is fixedly equipped with a mesh layer along the edges of the 2 length directions.There is a cutting gauze between the 2 mesh layers,and the 2 length edges of the cutting gauze are fixedly connected to the mesh layer.There is a plastic film between the cutting gauze and the middle dressing layer,and cracks are evenly spaced along the length direction of the cutting gauze.The top surface of the middle dressing layer is marked with a second scale.There is an opening at the connection between the lower dressing and the middle dressing,and the bottom surface of the lower dressing is an adhesive layer.This utility model,simple design,good fixing effect,convenient replacement,can avoid catheter slippage and displacement,reduce the occurrence of pressure-related injuries to instruments,and improve the quality of clinical work.It is worth promoting and applying in clinical practice.

Tumor immune microenvironment has been the focus of tumor research in recent years, and its role in tumor regulation has become prominent and has received increasing attention. The imbalance of the tumor immune microenvironment plays an important role in promoting tumor progression, and the adjustment of its instability plays an important role in controlling tumor progression. The theoretical idea of Traditional Chinese Medicine's "Yipingweiqi" is basically the same as that of modern medicine of controlling tumors by maintaining the balance of the immune microenvironment. This study discusses the aspects of tumor immune microenvironment, its destabilization, relationship to tumor progression, importance in Traditional Chinese Medicine, and regulation by Traditional Chinese Medicine with different treatments. In particular, this work focuses on the role of Traditional Chinese Medicine in maintaining the balance of the tumor immune microenvironment and its potential mechanism by using qi benefit, yang warming, dampness eliminating, and heat clearing under the guidance of the principle of "Yipingweiqi". Results will provide reference for the application of Traditional Chinese Medicine in the diagnosis and treatment of tumors.

Malignant pleural effusion is a heterogeneous disease,usually caused by metastasis of other tumors to the pleura,which belongs to the terminal state of malignant tumors.Compared with distant metastases from other sites,malignant pleural effusion brings more pain and difficulty in clinical management,and malignant pleural effusion caused by lung cancer is more common.How to choose personalized treatment for these patients is a problem that has attracted wide attention and controversy at present.Accurate prediction of the survival time and prognosis of patients with malignant pleural effusion can provide a breakthrough for these problems.In this paper,several mature and widely accepted prediction models of malignant pleural effusion are introduced,and some common problems are summarized,in order to provide new ideas for survival prediction of lung cancer with malignant pleural effusion.

At present, there are few relevant studies on gynecological tumors associated with sleep disorders, and there is a lack of research on TCM syndromes, so there is no targeted treatment plan. This article mainly introduces the present situation of diagnosis and treatment of sleep disorders caused by gynecological tumors in Chinese and western medicine, to provide reference for further study.

Objective:To explore the effects of infant sleep patterns on maternal sleep quality.Methods:Three hundred and nineteen pairs of mothers and infants from two grade three class-a hospitals in Nantong City were enrolled. Infant sleep patterns were assessed by the Brief Infant Sleep Questionnaire (BISQ). Maternal sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI). The effect of infant sleep patterns on maternal sleep quality was analyzed by one-way ANOVA followed with multivariate analysis.Results:The maternal sleep quality scored 7.08±2.60. Single factor analysis pointed out that the sleep quality of women whose infants slept in bed near parents, woke up more than 3 times a night, was nocturnal wakefulness more than 60 minutes or nocturnal sleep duration less than 8 hours was significantly worse. After controlling for confounding variables, the way of baby falling asleep, numbers of night wakings, nocturnal sleep duration, maternal age, infant′s gender and primary caregiver were independent factors of maternal sleep quality.Conclusion:Infant sleep pattern is an important factor affecting maternal sleep quality. Nurses should provide information about the sleep patterns of infants to mothers and their family members to promote their babies′ sleep habits so as to improve the maternal sleep quality.
