Objective To explore the relationship between basic motor skills and social interaction ability in school-age children with moderate autism,and the mediating role of executive function and the realization path.Methods A cross-sectional design was used to investigate 117 school-age children with autism from Sep.to Dec.2020.The level of basic motor skills was assessed by the test of gross motor development(TGMD),the impairment of executive function was assessed by the behavior rating inventory of executive function(BRIEF),and the social disorder was assessed by the social responsive scale-second edition(SRS-2).Pearson correlation analysis was used to explore the interrelationship,and structural equation modeling was applied to explore the path relationship.Results There was a significant negative correlation between the level of basic motor skills and SRS-2 scores(r=-0.312,P＜0.001).There were significant negative correlations between the level of basic motor skills and the BRIEF scores of inhibition(r=-0.336,P＜0.001),switching(r=-0.325,P＜0.001),affective control(r=-0.338,P＜0.001),task initiation(r=-0.240,P=0.009),working memory(r=-0.278,P=0.002),and planning(r=-0.224,P=0.015).The SRS-2 score was positively correlated with the BRIEF scores of inhibition(r=0.378,P＜0.001),switching(r=0.299,P=0.001),affective control(r=0.417,P＜0.001),task initiation(r=0.246,P=0.007),working memory(r=0.409,P＜0.001),and monitoring(r=0.258,P=0.005).Executive function played a complete intermediary role between basic motor skills and social interaction ability(B=-1.912,95％confidence interval:-3.116 to-1.069).Conclusion In school-age children with moderate autism,executive function and social interaction ability change positively with the level of basic motor skills.Basic motor skills can affect social interaction ability through the mediating role of executive function,and inhibition and affective control are important pathways to achieve this.

The use of checkpoint-blockade antibodies is still restricted in several malignancies due to the modest efficacy, despite considerable success in anti-tumor immunotherapy. The poor response of cancer cells to immune destruction is an essential contributor to the failure of checkpoint therapy. We hypothesized that combining checkpoint therapy with natural-product chemosensitizer could enhance immune response. Herein, a targeted diterpenoid derivative was integrated with the checkpoint blockade (anti-CTLA-4) to improve immunotherapy using thermosensitive liposomes as carriers. In vivo, the liposomes enabled the co-delivery of the two drug payloads into the tumor. Consequently, the regulatory T cell proliferation was restrained, the cytotoxic T cell infiltration was enhanced, and the profound immunotherapeutic effect was achieved. In addition, the immunotherapeutic effect of another clinically used checkpoint antibody, anti-PD-1, also benefited from the diterpenoid derivative. Of note, our mechanism study revealed that the targeted diterpenoid derivative increased the sensitivity of cancer cells to immune attack via THBS1 downregulation and the resultant destruction of THBS1-CD47 interaction. Collectively, co-delivering THBS1 inhibitor and checkpoint blockade is promising to boost cancer immunotherapy. We first time discovered that THBS1 suppression could strengthen checkpoint therapy.

Messenger RNA (mRNA) is the template for protein biosynthesis and is emerging as an essential active molecule to combat various diseases, including viral infection and cancer. Especially, mRNA-based vaccines, as a new type of vaccine, have played a leading role in fighting against the current global pandemic of COVID-19. However, the inherent drawbacks, including large size, negative charge, and instability, hinder its use as a therapeutic agent. Lipid carriers are distinguishable and promising vehicles for mRNA delivery, owning the capacity to encapsulate and deliver negatively charged drugs to the targeted tissues and release cargoes at the desired time. Here, we first summarized the structure and properties of different lipid carriers, such as liposomes, liposome-like nanoparticles, solid lipid nanoparticles, lipid-polymer hybrid nanoparticles, nanoemulsions, exosomes and lipoprotein particles, and their applications in delivering mRNA. Then, the development of lipid-based formulations as vaccine delivery systems was discussed and highlighted. Recent advancements in the mRNA vaccine of COVID-19 were emphasized. Finally, we described our future vision and perspectives in this field.

OBJECTIVE To provide a reference for the safe use of drugs in patients with complex venous thromboembolism （VTE） and acute renal insufficiency. METHODS Clinical pharmacists participated in the management of anticoagulant therapy for a patient with complex VTE complicated with acute renal insufficiency， and evaluated the patient as high-risk thrombosis and bleeding based on their medical history， laboratory test results， etc.； combined with the complexity of thrombosis and renal insufficiency， clinical pharmacists suggested that enoxaparin sodium should be used in the acute stage of thrombosis （5 to 21 days after onset）， and then warfarin should be adopted for oral anticoagulation treatment. Because the patient’s anticoagulation was not up to the standard （the target range of the international normalized ratio was 2-3）， clinical pharmacists suggested increasing the warfarin dose， detecting the warfarin metabolism genotype， and adjusting the warfarin dose according to the genotype； at the same time， clinical pharmacists developed an anticoagulation monitoring plan to ensure the safety of anticoagulation treatment. RESULTS Doctors had adopted all the recommendations of clinical pharmacists. The patient did not experience adverse events such as bleeding or worsening of thromboembolism during anticoagulation in the hospital. When the anticoagulation met the standards， the patient was allowed to be discharged with medication. CONCLUSIONS By participating in the anticoagulation treatment management of patients with complex VTE and acute renal insufficiency， clinical pharmacists have assisted doctors in formulating personalized anticoagulation plans to promote the compliance with the anticoagulation treatment standard and ensure the safety and effectiveness of medication for patients.

Objective:To investigate the treatment options for multiple myeloma patients with central nervous system involvement (CNS-MM) , as well as their clinical characteristics and prognostic factors.Methods:Between January 2011 and January 2022 our center diagnosed 18 people with CNS-MM. A retrospective analysis was done on the clinical information from the initial diagnosis and central nervous system involvement, and it was compared to 1∶3 matched newly diagnosed MM from the same period. Analysis was done on the clinical characteristics and survival rates of the two groups.Results:In patients with CNS-MM, the median time of onset was 14.2 (0.9-79.6) months and the median overall survival (OS) was 30.5 months from initial diagnosis and only 3.8 months in patients after CNS involvement. The CNS-MM patients showed more IgD type ( P=0.010) , severer anemia ( P=0.014) , a higher proportion of bone marrow plasma cells ( P=0.013) , more extramedullary lesions ( P=0.001) , and increased lactic dehydrogenase (LDH) ( P=0.009) when compared to the control group. Lenalidomide or pomalidomide-based combinations had higher rates of hematology and CNS remission than bortezomib or daratumumab-based regimens (75.0% vs 16.7% , P=0.019) . Patients who received IMiD-based regimens and had 2 high-risk factors at initial diagnosis (high LDH and extramedullary lesions) had a significantly lower incidence of CNS-MM ( P=0.026) . At the initial diagnosis, LDH ( P=0.008, HR=7.319, 95% CI 1.663-32.219) and extramedullary lesions ( P=0.006, HR=8.054, 95% CI 1.828-35.486) were independent risk factors for the occurrence of CNS-MM. Conclusion:Patients with CNS-MM had a poor prognosis. Patients with high LDH or extramedullary lesions at the time of the initial diagnosis are more likely to have CNS-MM. The prognosis of this patient may be improved by immunoregulator-based therapy.

Objective:To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM) .Methods:The clinical characteristics, adverse reactions, efficacy, and prognosis of 46 patients with RRMM treated with daratumumab in Shanghai Changzheng Hospital from September 2017 to March 2020 were retrospectively analyzed.Results:All patients were treated with daratumumab-based regimen: 8 in the Dd group, 35 in the DRd group, and 3 in the DVd group. With a median follow-up of 9.6 months, the overall response rate (ORR) was 75% [complete remission (CR) rate 18.2% ] among the 44 patients available for evaluation. The ORRs of patients resistant to bortezomib, lenalidomide, and both were 70.6% , 69.2% , and 63.6% , respectively. The CR rates of patients resistant to bortezomib, lenalidomide, and both were 17.6% , 11.5% , and 13.6% , respectively. No significant difference was observed in ORR and CR rates among the three groups. The ORRs of the DRd, DVd, and Dd groups were 85.3% , 66.7% , and 28.6% , respectively ( P=0.007) . The median PFS of 46 patients was 8.9 months, the median OS was not reached, and the 1-year OS rate was 74% . The median PFS and OS in the DRd group were longer than those in the Dd group (PFS: 14.4 months vs 2.0 months; OS: not reached vs 5.2 months) . After treatment with daratumumab, neutropenia is the most common hematological adverse reaction above grade 3. Non-hematological adverse reactions are mainly infusion-related adverse reactions and infections. Prognostic analysis showed that patients with extramedullary invasion had shorter PFS and OS compard with patients without extramedullary invasion (PFS: 5.7 vs 14.4 months, P=0.033; OS: 6.3 months vs not reached, P=0.029) . The OS of patients with an ECOG score of 3-4 was significantly shorter than patients with an ECOG score of 1-2 (5.9 months vs not reached, P=0.004) . Conclusion:Daratumumab-based regimens have good efficacy and safety in the treatment of RRMM.

Objective:To explore the application and effect of autologous cartilage in rhinoplasty for patients with traumatic hernia and nasal dysfunction.Methods:From January 2017 to April 2019,30 patients with nasal trauma admitted to Department of Otorhinolaryngology Head and Neck Surgery, Daping Hospital, Army Medical University were treated for 6 days to 14 years. All patients were accompanied by different degrees of nasal deformity and nasal ventilatory disorders. They were classified into three categories: light, medium and heavy. All of them were open at the same time. Rhinoplasty and nasal septum deviation correction. For mild to moderate nasal deformity and nasal ventilatory disorders, ear cartilage was used to modify the tip of the nose and strengthen the nasal septal cartilage support to modify the deformity of the nasal back. For severe nasal deformity and nasal ventilatory disorders, we engraved the costal cartilage into a "Y" shaped monolithic stent or flank costal cartilage to form a 2+1 or 4+1 stent, and the costal cartilage stent and the septal cartilage tail end were sutured. Reshape the nasal septum frame support and the nasal column to avoid collapse of the nose.Results:Three patients had a septal hematoma after operation and recovered normally after cleansing. All patients were followed up for 2 months to 2 years, and no complications such as nasal septum perforation and nasal bridge collapse occurred. The postoperative cure rate was 60.0% (18/30). All patients had a grade I nasal drop after surgery, and the effective rate was 100% (30/30). The patient′s preoperative measurement deviation was (6.85±2.43) mm, the postoperative measurement deviation was (2.4±1.58) mm, the preoperative nasal appearance VAS score was (1.93±1.31), and the postoperative nasal appearance VAS score was (6.60±1.16), the difference in facial appearance deviation and VAS score before and after surgery was statistically significant ( P<0.05). All patients had improved nasal ventilation after operation. The preoperative nasal ventilation VAS score was (1.97±1.07), the postoperative nasal ventilation VAS score was (6.53±1.04), and the difference between preoperative and postoperative nasal ventilation VAS scores was statistically significant ( P<0.05). Conclusions:Autologous cartilage is effective in rhinoplasty in patients with traumatic nasal contraction and nasal dysfunction. One stage open rhinoplasty and nasal septum deviation surgery are performed to shorten the treatment time and improve the nasal appearance and nasal ventilation function. The patients got satisfaction.

Objective:To evaluate the effect of exercise on the sleep quality of elderly persons experiencing a sleep disorder so as to provide an evidentiary basis for future studies.Methods:Reports of randomized and controlled trials of the effects of exercise on sleep quality among elderly persons with sleep disorders were extracted from the Cochrane library, PubMed, EMbase, the Web of Science, CNKI and other databases. Reports from the database′s inception to August 28, 2019 were retrieved. All were screened applying inclusion and exclusion criteria, and their methodological quality was evaluated using the Cochrane bias risk tool. The combined effect was analyzed using version 5.0 of the ReMan software.Results:Nine reports covering 928 patients were identified. Meta-analysis showed that compared with the control group, exercise could significantly improve the overall sleep quality of elderly patients with sleep disorders in terms of sleep score, subjective sleep quality, sleep latency, sleep duration, sleep efficiency, degree of sleep disturbance, sleep medication use, and daytime functioning.Conclusion:Exercise can improve the overall sleep quality of patients with a sleep disorder, shortening the sleep latency, improving sleep efficiency, reducing the use of sleep drugs, and improving their daytime functioning. However, it has less effect on subjective evaluations of sleep quality and sleep disorder.

Objective:To explore the influencing factors of 31-day unplanned readmission in obstetrics.Methods:The medical records and relevant clinical data of 29 public hospitals in a province in 2017 were collected to construct a two-level logistic regression model on the influencing factors of 31-day unplanned readmission.Results:In 2017, there were 71 330 obstetric patients discharged from 29 public hospitals, 690 of whom were unplanned readmitted in 31 days, accounting for 0.97%. The type of medical insurance payment, number of previous hospitalization, condition of previous hospitalization, age, history of cesarean section, pregnancy complications and complications during delivery were all the factors influencing the 31-day unplanned readmission of obstetrics.Conclusions:The condition of 31-day unplanned readmission could be influenced by the factors of sociology, previous visit and clinical. These factors should be considered reasonably in the evaluation and management of obstetric quality.
