Matrix metalloproteinases-9(MMP-9) is an important gene in coloreetal cancer occurrence and development.MMP-9 can induce cell proliferation,angiogenesis and neoplasm infiltration,and then leads to coloreetal cancer invasion and metastasis.MMP-9 can not only play the role individually in coloreetal canccr invasion and migration,but also can cooperate with other genes.MMP-9 is a key protease in terminal metastasis of coloreetal cancer.

OBJECTIVE: To present the surgical outcomes of advanced epithelial ovarian cancer (AEOC) since the implementation of a personalized approach and to validate multiple predictive models for R0 resection. METHODS: Personalized strategies included: 1) Non-invasive model: preoperative clinico-radiological assessment according to Suidan criteria with a predictive score for all individuals. Patients with a score 0–2 were recommended for primary debulking surgery (PDS, group A), or otherwise were counseled on the choices of PDS, neoadjuvant chemotherapy (NAC, group B) or staging laparoscopy (S-LPS). 2) Minimally invasive model: S-LPS with a predictive index value (PIV) according to Fagotti. Individuals with a PIV < 8 underwent PDS (group C) or otherwise received NAC (group D). Intraoperative assessment (with Eisenkop, peritoneal cancer index [PCI], and Aletti scores) and surgical results were prospectively collected. RESULTS: Between September 2015 and August 2017, 161 pathologically confirmed epithelial ovarian cancer patients were included. A total of 52 (32.3%) patients had a predictive score of 0–2, and 109 (67.7%) patients had a score ≥ 3. Among these individuals, 41 (25.5%) patients received S-LPS. Finally, 110 (68.3%) patients underwent PDS (A+C), and 51 (31.7%) patients received NAC (B+D). The R0 resection rates in PDS and NAC patients were 56.4% and 60.8%, respectively. The area under the curve (AUC) of Suidan criteria was 0.548 for group (A+C). The AUC of Fagotti score was 0.702 for group C. The AUC of Eisenkop, PCI, and Aletti scores were 0.808, 0.797, and 0.524, respectively. CONCLUSION: The Suidan criteria were not effective in these AEOC patients. S-LPS was helpful in decision-making for PDS and should be endorsed in the future.

The standardization of pediatric Tuina is beneficial to pediatric Tuina practitioners in a norm practices. The paper collects the content from teaching textbooks, TCM ancient books and database literature, and tries to develop the technical specifications of pediatric Tuina by four rounds Delphi surveys and expert consensus. This specification covers the manipulation of pediatric Tuina, the position of acupoints, the effects of acupoints and the diagnosis and treatment of pediatric Tuina, including indications, contraindications, cautious use, operation steps and methods.

Regenerative endodontic procedures, based on dental pulp biology, use the basic principles of tissue engineering to promote the functional regeneration of dental pulp-dentin complexes. Good results have been achieved in the treatment of young permanent teeth with pulp necrosis or apical periodontitis. There have also been preliminary clinical explorations of the treatment of mature permanent teeth in recent years. The key to successful treatment is controlling infection as well as promoting tissue repair and regeneration. Moderate root canal mechanical preparation is allowed in the therapy of mature permanent teeth, while it is not recommended in the treatment of young permanent teeth. The choice of root canal irrigation and intracanal antisepsis requires a comprehensive consideration of the antibacterial effects, biological safety, and possible complications, such as crown discoloration and root canal calcification. The development of bioceramic materials provides more options for crown sealing materials, but further clinical evaluation is needed. In addition to traditional blood clot scaffolds, new types of tissue scaffolds represented by platelet-rich plasma, platelet-rich fibrin, concentrated growth factors and other platelet concentrates have been developed. Long-term and large-scale studies are needed to evaluate the actual clinical efficacy of these new scaffolds and the efficacy of their combined application with blood clots.

ObjectiveTo explore sleep disturbance in preschool children with autism spectrum disorder (ASD) and analyze the relationship between sleep disturbance and social behavior. MethodsFrom December, 2020 to December, 2022, 221 preschool children with ASD from Beijing Bo'ai Hospital and other two institutes, and 246 healthy preschool children socially recruited were investigated with Children's Sleep Habits Questionnaire (CSHQ). A total of 47 ASD children and 47 healthy children were selected from them to wear a sleep monitoring watch for seven days, while the ASD children were evaluated with Gesell Development Diagnosis Scale (GDDS), Psychoeducational Profile-Third Edition (PEP-3), Autism Diagnostic Observation Schedule-2 (ADOS), Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS) and Social Responsiveness Scale (SRS). ResultsAll the factor-scores were more in the ASD children than in the healthy children (t > 2.491, P < 0.05), except that of daytime sleepiness. The prevalence of sleep disturbance (CSHQ ≥ 41) was 89.6% in ASD children, which was more than that of the healthy children (76.8%) (χ2 = 13.360, P < 0.001). The sleep problems in ASD children included bedtime resistance, sleep anxiety, sleep duration, sleep onset delay, parasomnias and sleep disordered breathing. ASD children were shorter in total bedtime, shorter in total sleep time, longer in sleep latency, longer in awake time and lower in sleep efficiency (|t| > 2.001, P < 0.05), compared with those of healthy children. For ASD children, the total bedtime negatively correlated with GDDS-language, PEP-3-expressive language, PEP-3-communication and PEP-3-maladaptive behaviors (r < -0.300, P < 0.05); the sleep efficiency negatively correlated with total score of CARS (r = -0.365, P < 0.05); sleep latency correlated with GDDS-social, PEP-3-cognitive, PEP-3-expressive language, PEP-3-receptive language, PEP-3-visual-motor imitation, PEP-3-characteristic verbal behaviors, PEP-3-communication, original score of ADOS, ADOS-social affect, and total score of CARS (|r| > 2.90, P < 0.05); and total awake time positively correlated with total score of CARS (r = 0.406, P < 0.05). ConclusionSleep disturbance is prevalent and various in preschool ASD children, and influence their social behaviors.
