Objective:To systematically evaluate the intervention effect of acceptance commitment therapy on anxiety disorder.Methods:The full-text databases of Web of Science Core Collection, MEDLINE, KCI-Korean Journal Database, SciELO Citation Index, SpringerLink, Pubmed, EMBASE, Cochrane Library, CNKI Wanfang and Weipu were searched and randomized controlled studies related to acceptance commitment therapy for patients with anxiety disorder were collected.All randomized controlled studies met the criterion were included.Meanwhile, the literature quality of the included literatures was evaluated.The outcome indicators such as anxiety index, psychological flexibility and quality of life index were selected, and RevMan 5.3 software was used to analyze the literature data that met the inclusion criteria.Results:A total of 12 studies with 1 062 patients were included, including 513 cases in ACT group and 549 cases in control group.Meta analysis showed that ACT can effectively reduce anxiety level of patients with anxiety disorder (MD=-0.58, 95% CI: -0.85- -0.32, P<0.001), anxiety level in follow-up period (MD=-0.42, 95% CI: -0.75- -0.08, P=0.01), improving psychological flexibility (MD=0.46, 95% CI: 0.24~0.68, P<0.001); In the study of CBT(cognitive behavioral therapy) as the control group, there was no significant difference between ACT group and control group, among which after intervention (MD =-0.06, 95% CI: -0.47- 0.36, P=0.79), follow-up period (MD = 0.17, 95% CI: -0.07-0.41, P=0.16) .In the study with the control group as the blank control, ACT can reduce the anxiety level of patients with anxiety disorder (MD =-0.76, 95% CI: -0.97- -0.56, P<0.001), and the difference is statistically significant.Excluding the non-blank control study, ACT can reduce the anxiety level of patients with anxiety disorder (MD =-0.82, 95% CI: -1.09--0.55, P<0.001) in the studies where the proportion of women is greater than or equal to 70%.In the study of 50%-70% females, ACT can reduce the anxiety level of patients with anxiety disorder (MD =-0.68, 95% CI: -1.09 --0.28, P=0.01). All the differences were statistically significant.There was no significant difference between ACT and the control group for quality of life(MD=0.24, 95% CI: -0.01-0.49, P=0.06). Conclusion:ACT has a certain effect on patients with anxiety disorder, which not only improves the anxiety level of patients, but also keeps the effect of anxiety improvement during the follow-up period, and the improvement of psychological flexibility has also been verified.The immediate and long-term efficacy of ACT is similar to that of CBT, which further improve the reliability of ACT curative effect.Gender difference has not been confirmed for the therapeutic effect.ACT has no obvious improvement on the quality of life, and the conclusion of this study needs more randomized controlled studies with large samples and high quality to verify it.

Objective Based on the theory of"lung governs the skin and hair"in"Yellow Emperor's Inner Classic",this paper analyzes the medication rules of whitening and freckle-removing.The aim of this study is to provide reference for the clinical practice of traditional Chinese medicine(TCM)theory and the medication in TCM cosmetics.Methods"Chinese Medical Classics"was used to search the records of whitening and freckle-related drugs.The frequency,nature,flavor,meridian tropism and compatibility laws of TCM for whitening and freckle-removal were analyzed by statistics and association rules.The network pharmacology research was used to analyze the whitening and freckle-removing effects and mechanisms of high-frequency drugs.Then,the potential active ingredients were analyzed.The whitening and anti-freckle effect was verified through cytotoxicity experiments and melanin content detection.Results A total of 171 external prescriptions were selected in eligible articles,including 261 Chinese medicinals,most of which were pungent and belong to the lung meridian.The most frequently used Chinese medicinals was"Erbai Yixin"(EBYX,Angelicae Dahuricae Radix,Typhonii Rhizoma,Asari Radix et Rhizoma).Network pharmacological analysis showed that the core targets of EBYX for whitening and removing freckles are TP53,EGFR,ALB,etc.,which are mainly involved in oxygen perception and response,skin immune regulation,skin cell growth,differentiation,stress,inflammatory response,and other biological processes.Based on the results of molecular docking,biological analysis proved that the active ingredients of EBYX are chrysophanol,gallic acid and caffeic acid,which have inhibitory effects on the proliferation of melanoma cells and melanin production.Conclusion Most of the ancient prescriptions for whitening and removing freckles are pungent and belong to the lung meridian,which embodies the theory of"lung governs the skin and hair".The high-frequency drug EBYX may play a role by regulating skin redox,immunity and inflammation.The active ingredients of EBYX have an inhibitory effect on melanin formation.This study enriches the scientific connotation of TCM whitening and freckle-removing prescriptions based on the theory of"lung governs the skin and hair",realizes interdisciplinary integration and provides support for the modernization of TCM.

Objective·To analyze the clinical and genetic characteristics of Chinese pediatric patients with Barth syndrome(BTHS)and provide data to support the prevention and treatment of BTHS.Methods·Eighteen pediatric patients diagnosed with BTHS at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,from January 2010 to November 2023,were included.Clinical data(age,birth weight,family history,electrocardiogram,echocardiogram,urine tandem mass spectrometry,complete blood count,blood biochemistry,and genetic test results)were collected to analyze the clinical characteristics,genetic findings,and prognoses of the patients.Results·The study included 18 male patients with BTHS(including 2 monozygotic twins),consisting of one Yi ethnic and 17 Han Chinese patients.The median age at diagnosis was 3.0(1.0,5.6)months.Fifteen patients experienced decreased cardiac function at disease onset,with a left ventricular ejection fraction(LVEF)below 50%.Dilated cardiomyopathy(DCM)was observed in 15 patients,left ventricular non-compaction(LVNC)in 12 patients,and myocardial hypertrophy in 9 patients.During the diagnosis and follow-up,QTc interval prolongation occurred in 9 patients,ventricular arrhythmias in 2 patients,neutropenia in 9 patients,and monocytosis in 10 patients.Urine tandem mass spectrometry revealed 3-methylglutaconic aciduria(3-MGCA)in 8 of 13 tested patients.Fifteen types of TAZ gene mutation were identified in the 18 patients,including 5 novel mutations.Genetic testing of the parents of 16 patients indicated maternal inheritance in 15 cases.The median follow-up period was 8.5(2.6,29.3)months,during which 12 patients died.The median age at death was 7.5(6.0,12.8)months.Causes of death included heart failure(7 cases,with 4 concurrent infections),sudden death(3 cases),ventricular fibrillation(1 case),and accidental death(1 case).Conclusion·BTHS is a rare genetic disorder with multisystem involvement.Its primary clinical manifestations include cardiomyopathy and neutropenia.The condition typically presents early in life,with severe progression and poor prognosis.Prompt recognition,accurate diagnosis,and early intervention are essential for managing this disease.

To evaluate five methods in the estimation on the rate of case fatality during the epidemics of diseases based on the summarizing data. Case fatality rates,derived from the simulation data,2003 SARS epidemic data in Hong Kong,Singapore Beijing and the 2013 H7N9 epidemic data in mainland China were analyzed,using these 5 methods. Results from the simulation analysis discovered that the relative errors and the standard deviations of the Chen[7,8] (method 3),Chen[9] (method 4) were minor with high accuracy. Data from the analysis on 2003 SARS epidemic was noticed that the estimation from method 3,4 in Hong Kong and Singapore both showing high veracities. Since the case fatality rate reported in Beijing was not a constant value,method 5 showed low accuracy even though it was close to the final case fatality rate. Data from the 2013 H7N9 epidemic showed that the estimations of method 1,2,3,4 were all higher than that in the method 5, suggesting that method 3,4 could be used to estimate the case fatality rates of epidemics more precisely.

Objective:To determine the expression of circular RNA-SEC31A(circSEC31A) in pancreatic cancer and investigate the effects on the invasion and migration of pancreatic cancer cells and the underlying molecular mechanism.Methods:Differentially expressed circRNAs between pancreatic cancer cells (BXPC-3, PANC1, CaPan-2, SW1990) and human normal pancreatic cells (HPDE) were identified by qRT-PCR. Then, two cell lines with high circSEC31A expression were selected to conduct next experiments. According to the sequence of the back-splicing site in circSEC31A, siRNAs for downregulation of circSEC31A were designed and transfected by liposome to silence circSEC31A in pancreatic cancer cells, and grouped as followed siR-circSEC31A#1 and siR-circSEC31A#2. Meanwhile, siR-NC group transfected with non-specific siRNA served as control. Transwell assays and wound healing assays were operated to evaluate the functional role of circSEC31A on the invasion and migration of pancreatic cancer cells. RNA Pull-down assay with circSEC31A probe and oligo control probe was used to screen the miRNA combining with circSEC31A and the effects of miRNA on cell invasion and migration of pancreatic cancer cells were validated. The effect of miR-200c-3p and circSEC31A silencing on the expression of PDK1 mRNA was identified by qRT-PCR. The protein expression of PDK1, downstream Akt and p-Akt after circSEC31A silencing was verified by Western blotting assays.Results:The relative expression level of circSEC31A in HPDE (1.000±0.120) was obviously lower than that in BXPC-3 (1.920±0.130), SW1990 (2.93±0.528), PANC1 (4.557±0.692) and CaPan-2 (5.247±0.194), and all the differences were statistically significant ( P<0.001). Compared with the PANC1 siR-NC group (1301.3±94.6) and CaPan-2 siR-NC group (1835.0±70.1) per 100 high power field, transwell assays showed that the numbers of invasive pancreatic cancer cells was highly decreased in PANC1 siR-circSEC31A#1 group (727.3±92.9), siR-circSEC31A#2 group (792.0±18.1), CaPan-2 siR-circSEC31A#1 group (718.0±90.6), siR-circSEC31A#2 group (692.7±84.8). Wound healing assays showed that silencing circSEC31A decreased the wound healing rate of pancreatic cancer cells in PANC1 siR-circSEC31A#1 group (20.667±3.215)%, siR-circSEC31A#2 group (20.000±4.583)%, CaPan-2 siR-circSEC31A#1 group (28.000±8.185)%, siR-circSEC31A#2 group (29.667±5.686)%, compared with the PANC1 siR-NC group (55.000±4.359)% and CaPan-2 siR-NC group (69.000±3.606)%. RNA Pull-down assays showed that compared with PANC1 oligo probe group (1.000±0.091) and CaPan-2 oligo probe group (1.000±0.153), miR-200c-3p was significantly enriched in the PANC1 circSEC31A probe group (2.237±0.175) and CaPan-2 circSEC31A probe group (2.166±0.156). Compared with PANC1 siR-NC group (939.3±57.0) and CaPan-2 siR-NC group (786.7±51.5) per 100 high power field, the numbers of invasive pancreatic cancer cells were up-regulated in PANC1 siR-miR-200c-3p group (1206.0±99.1) and CaPan-2 siR-miR-200c-3p group (1838.0±105.7), while the low numbers of invasive pancreatic cancer cells were observed in PANC1 siR-miR-200c-3p+ siR-circSEC31A group (932.7±116.4) and CaPan-2 siR-miR-200c-3p+ siR-circSEC31A group (785.3±58.8). Compared with PANC1 siR-NC group (1.000±0.103) and CaPan-2 siR-NC group (1.000±0.107), the relative expression of PDK1 mRNA in PANC1 siR-miR-200c-3p group (1.898±0.159) and CaPan-2 siR-miR-200c-3p group (2.102±0.337) was upregulated. Furthermore, the expression of PDK1 mRNA was decreased in the siR-miR-200c-3p+ siR-circSEC31A group (0.980±0.070, 1.015±0.079). Western blot assays showed that the expression of PDK1 protein in PANC1 siR-NC group, siR-circSEC31A#1 group, siR-circSEC31A#2 group was 0.767±0.086, 0.281±0.191, 0.333±0.062 and in CaPan-2 siR-NC group, siR-circSEC31A#1 group, siR-circSEC31A#2 group was 0.712±0.038, 0.353±0.061, 0.308±0.018. The expression of p-Akt protein in PANC1 siR-NC group and siR-circSEC31A group was 0.741±0.050, 0.114±0.027, 0.139±0.041. In addition, p-Akt protein expression in CaPan-2 siR-NC group and siR-circSEC31A group was 0.823±0.052, 0.141±0.045, 0.280±0.089. PDK1 and p Akt expression in siR circSEC31A group was obviously lower than those in sir NC group. All the differences between either groups above were statistically significant ( P<0.05). Conclusions:circSEC31A is upregulated in pancreatic cancer cells, which facilitates the invasion and metastasis of pancreatic cancer cells via miR-200c-3p/PDK1/Akt signaling pathway, supporting that circSEC31A may function as a new diagnostic and therapeutic target for pancreatic cancer patients.

Objective:To investigate the efficacy of oblique lumbar interbody fusion (OLIF) combined with percutaneous transforaminal endoscopic decompression (PTED) and posterior pedicle fixation through Wiltse approach in the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis.Methods:From June 2017 to February 2022, 103 patients (50 males and 53 females) of lumbar spondylolisthesis accompanied with lumbar spinal stenosis were performed with OLIF combined with PTED and posterior pedicle fixation. The mean age was 64.1±5.2 years (range, 42-87 years). All involved cases were single-segment and included 83 cases of L 4, 5, 17 cases of L 3, 4, and 3 cases of L 2, 3. Among them, 94 cases were performed for the first time, and other 9 were revision surgery treated by posterior lumbar laminectomy previously. The visual analog scale (VAS) was used to evaluate the low back pain and leg pain, and the Oswestry disability index (ODI) was used to evaluate the lumbar function. The VAS and ODI scores were recorded respectively before the operation, at discharge, 1, 3, 6 months after the operation and at the last follow-up. Macnab criteria was used to evaluate the clinical efficacy at the last follow-up. At the same time, imaging measurements were conducted, including the anterior and posterior disc height, segmental lordotic angle, percentage of slip on lateral X-ray film and the vertebral canal area on axial MRI before and after surgery. Results:All of 103 patients were successfully operated in one stage with an average operation time of 177.7±21.5 min (range, 155-220 min), and an average intraoperative blood loss of 55.9±18.3 ml (range, 30-150 ml). The mean follow-up time were 15.1±2.6 months (range, 6-36 months). There were significant differences in both VAS scores of back and leg and ODI scores at each postoperative time point when compared with preoperative ( F=508.25, F=1524.82, F=1148.68, P<0.001). Macnab criteria of the last follow-up was evaluated as follow: excellent in 85 cases, good in 14, fair in 4, and the excellent and good rate was 96.1%. The radiographic results showed the mean immediate postoperative anterior disc height, posterior disc height, segmental lordotic angle, percentage of slip and axial area of the vertebral canal were 15.23±2.97 mm, 9.32±2.31 mm, 14.36°±4.18°, 3.89%±3.11%, 113.37±47.27 mm 2, and thus all of those increased significantly compared to the mean preoperative 11.93±3.17 mm, 7.21±2.03 mm, 6.15°±3.99°, 23.66%±7.79%, 57.63±28.91 mm 2, respectively ( t=7.84, t=7.07, t=14.91, t=27.62, t=9.68, P<0.001). All cases achieved bony fusion during 6-12 months after operation. The incidence of surgery-related complications was 10.7% (11/103). There were 3 cases of end plate fracture and 2 cases of dural injury, which had no complaint after operation. There was 1 case of pedicle screw entering into the spinal canal by mistake, and the symptoms of nerve damage appeared after operation. After 1 year it basically returned to normal. There were 2 cases of thigh numbness and 1 case of psoas major weakness after operation, all of which relieved after 4 weeks. There was 1 case continuous pain of abdominal incision after surgery. There was 1 case of cage subsidence at the last follow-up. Conclusion:OLIF combined with PTED and posterior pedicle fixation through Wiltse approach is a minimally invasive surgical method for the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis. With the combined minimally invasive techniques, the decompression, fusion and fixation of the lumbar spine can be fulfilled perfectly. It has the advantages of minimally invasive, good clical outcome, few complications and rapid rehabilitation.

It discusses the advantages, disadvantages, and application scenarios of these designs. Additionally, it explores the benefits of Bayes decision-making in clinical trials for rare diseases. The aim is to provide a reference for designing and implementing small sample clinical trials for rare diseases.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

The theory of"lung governing skin and hair"has always occupied an important position in the clinical practice of traditional Chinese medicine.However,in western medicine,the close correlation between the lungs and the skin in health and disease has not been established.The difference between these two medical views has triggered an urgent need for the scientific interpretation and clinical application of the theory of"lung governing skin and hair"in western medicine.Therefore,the purpose of this paper is to discuss the application of"lung governing skin and hair"in chinese medicine and the correlation between the lung and the skin in western medicine from the connotation and history of"lung governing skin and hair"in Chinese medicine.In addition,we will discuss the common pathologic biomarkers of lung and skin diseases in western medicine and the co-morbidities between lung and skin,with the aim to provide new ideas for the clinical diagnosis and treatment of lung and skin diseases and modern research,as well as providing a direction for the integration of the theory of"lung governing skin and hair"into the clinical practice of western medicine.
