ObjectiveBased on functional near-infrared spectroscopy (fNIRS), we investigated the brain activity characteristics of gross motor tasks in children with autism spectrum disorder (ASD) and motor dysfunctions (MDs) to provide a theoretical basis for further understanding the mechanism of MDs in children with ASD and designing targeted intervention programs from a central perspective. MethodsAccording to the inclusion and exclusion criteria, 48 children with ASD accompanied by MDs were recruited into the ASD group and 40 children with typically developing (TD) into the TD group. The fNIRS device was used to collect the information of blood oxygen changes in the cortical motor-related brain regions during single-handed bag throwing and tiptoe walking, and the differences in brain activation and functional connectivity between the two groups of children were analyzed from the perspective of brain activation and functional connectivity. ResultsCompared to the TD group, in the object manipulative motor task (one-handed bag throwing), the ASD group showed significantly reduced activation in both left sensorimotor cortex (SMC) and right secondary visual cortex (V2) (P<0.05), whereas the right pre-motor and supplementary motor cortex (PMC&SMA) had significantly higher activation (P<0.01) and showed bilateral brain region activity; in terms of brain functional integration, there was a significant decrease in the strength of brain functional connectivity (P<0.05) and was mainly associated with dorsolateral prefrontal cortex (DLPFC) and V2. In the body stability motor task (tiptoe walking), the ASD group had significantly higher activation in motor-related brain regions such as the DLPFC, SMC, and PMC&SMA (P<0.05) and showed bilateral brain region activity; in terms of brain functional integration, the ASD group had lower strength of brain functional connectivity (P<0.05) and was mainly associated with PMC&SMA and V2. ConclusionChildren with ASD exhibit abnormal brain functional activity characteristics specific to different gross motor tasks in object manipulative and body stability, reflecting insufficient or excessive compensatory activation of local brain regions and impaired cross-regions integration, which may be a potential reason for the poorer gross motor performance of children with ASD, and meanwhile provides data support for further unraveling the mechanisms underlying the occurrence of MDs in the context of ASD and designing targeted intervention programs from a central perspective.

CONCLUSIONS The process of weight determination in this indicator system is scientifically reasonable， with clear methods and clear interpretations， and is worthy of further optimization and widespread application.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.

Objective:To identify risk factors for infections by multidrug-resistant organisms(MDRO)in elderly patients admitted to the intensive care unit(ICU)based on an retrospective analysis of data from the Medical Information Mart for Intensive Care-Ⅳ v2.0(MIMIC-Ⅳ v2.0).Methods:Structured query language was used to extract basic information, disease severity scores, laboratory test results, medications, medical procedures, and outcome events of elderly patients from MIMIC-Ⅳ v2.0.Patients were divided into a non-MDRO group and an MDRO group based on whether they had MDRO infections.Univariate analysis was performed according to the type of variables.For significant variables identified from univariate analysis, logistic regression was used to calculate the odds ratio and the 95% confidence interval for MDRO infections.The Kaplan-Meier method was used to draw survival curves.The log-rank test was used to analyze the 28-day survival rate.Results:A total of 31 237 cases were enrolled, including 26 032 with non-MDRO infections and 5 205 with MDRO infections.The MDRO infection rate was 16.7%.MDRO were most frequently found in urine cultures, and the most common bacteria belonged to the genus Enterobacter.Multivariate logistic regression analysis showed that age( P=0.006), being male( P<0.001), coronary artery disease( P<0.001), brain disease( P=0.042), hemoglobin( P<0.001), albumin( P<0.001), and mechanical ventilation( P<0.001)were protective factors against MDRO infections.Diabetes( P<0.001), COPD( P<0.001), chronic kidney disease( P<0.001), white blood cell( P=0.001), SAPS Ⅱ( P<0.001), previous use of antibiotics( P<0.001), use of proton pump inhibitors( P<0.001), glucocorticoids( P<0.001), immunosuppressants( P<0.001)and sedatives( P<0.001), and continuous renal replacement therapy(CRRT)( P=0.015)were risk factors for MDRO infections.The 28-day mortality rates of the non-MDRO and MDRO groups were 16.3% and 19.1%, respectively.The log-rank test showed that the difference between two groups was statistically significant( P<0.001). Conclusions:The mortality rate among patients with MDRO infections is higher than among those with non-MDRO infections.Previous use of antibiotics, use of proton pump inhibitors, glucocorticoids, immunosuppressants and sedatives, mechanical ventilation, and CRRT are risk factors for MDRO infections.

AIM To analyze the constituents absorbed into blood and brain from Zhishe Tongluo Capsules.METHODS Sixteen rats were randomly assigned into four groups and given intragastric administration(3.1 g/kg),after which the cerebral ischemia-reperfusion injury(MACO)model was established,the blood and brain tissues were collected,and UHPLC-Q Exactive Focus MS/MS was adopted in the identification of prototype constituents.RESULTS Total 70 constituents were identified,20 of which were found in the blood,mainly including flavonoids,tanshinones and Ligusticum chuanxiong phthalides,and 7 of them could enter the brain through blood-brain barrier.Compared with the normal administration group,the MACO administration group demonstrated added constituents absorbed into blood containing 3-hydroxybenzoic acid,calycosin-7-glucoside,curcumenol,senkyunolide B,dihydrotanshinone I and cryptotanshinone;removed constituents absorbed into brain containing puerarin,elemicin,sedanolide,and added those containing salvianolic acid A,senkyunolide I,dihydrotanshinone I in the left brain tissues(infarcted side).CONCLUSION The constituents absorbed into blood and brain from Zhishe Tongluo Capsules,along with the enhanced absorptions of phthalides,quinones and phenols in MACO rats in vivo may be the active substances for treating cerebral infarction.

AIM To observe the protective effects of Qigu Capsule-medicated serum on C2C12 myotube cell atrophy induced by dexamethasone.METHODS The Qigu Capsule-medicated serum was prepared.C2C12 cells cultured in vitro were divided into the normal control group,the dexamethasone group,the 10%blank serum group and the 10%Qigu Capsule-medicated serum group for 48 h,corresponding drug treatment,followed by 24 h culture with 10 μmol/L dexamethasone except the control group,and had cell viability detection by CCK-8 method.With their myotube cells intervened accordingly by the aforementioned regime following 6-7 days differentiation with 2%horse serum induction,the C2C12 cells had their myotube cells diameter measured;and the expressions of proteins related to MyHC,MuRF-1,Atrogin-1 and PI3K/Akt signaling pathway detected by Western blot.The impact of PI3K inhibitor LY294002 on the diameter of myotube cells and the expression of MuRF-1,Atorgin-1 and PI3K/Akt signaling pathway related proteins were detected as well.RESULTS Compared with the normal control group,the dexamethasone group and the blank serum group were observed with decreased viability of C2C12 cells(P<0.01),decreased diameter of myotube cells(P<0.01),increased protein expressions of MuRF-1 and Atrogin-1(P<0.01),and decreased expression of MyHC protein and phosphorylation levels of PI3K,Akt,mTOR and FoxO3a(P<0.01).Compared with the dexamethasone group,the Qigu Capsule-medicated serum group showed increased viability of C2C12 cells(P<0.01);increased diameter of myotube cells(P<0.01);decreased protein expressions of MuRF-1 and Atrogin-1(P<0.01);and increased expression of MyHC protein and phosphorylation levels of PI3K,Akt,mTOR and FoxO3a(P<0.05,P<0.01).The intervention of LY294002 upon the Qigu Capsule-medicated serum group offset the anti-muscular tube atrophy effect(P<0.01),increased the protein expressions of MuRF-1 and Atorgin-1(P<0.01),and decreased the phosphorylation levels of PI3K,Akt,mTOR and FoxO3a(P<0.05,P<0.01).CONCLUSION The Qigu Capsule-medicated serum can alleviate the atrophy of C2C12 myotubes induced by dexamethasone,and its mechanism may be related to the activation of PI3K/Akt signaling pathway.

WHO Guideline on Country Pharmaceutical Pricing Policies,published in 2020,outlines 10 commonly used pricing methods internationally.However,due to the unique composition of costs for traditional Chinese medicine(TCM),directly applying pricing methods designed for chemical and biological drugs may lead to discrepancies.Currently,in China,drug pricing primarily in-volves internal reference pricing,tender negotiation pricing,promoting the use of quality-assured generic and biosimilar drugs,and centralized procurement.It systematically analyzes various pricing methods and identifies their applicability and underlying reasons concerning the pricing of TCMwithin the medical insurance system.The method of value-based pricing and increasing price transparency has advantages for the pricing regulation of traditional Chinese medicine under medical insurance.

OBJECTIVE: Clinical characteristics and outcome in COVID-19 with brucellosis patients has not been well demonstrated, we tried to analyze clinical outcome in local and literature COVID-19 cases with brucellosis before and after recovery. METHODS: We retrospectively collected hospitalization data of comorbid patients and prospectively followed up after discharge in Heilongjiang Infectious Disease Hospital from January 15, 2020 to April 29, 2022. Demographics, epidemiological, clinical symptoms, radiological and laboratory data, treatment medicines and outcomes, and follow up were analyzed, and findings of a systematic review were demonstrated. RESULTS: A total of four COVID-19 with brucellosis patients were included. One patient had active brucellosis before covid and 3 patients had nonactive brucellosis before brucellosis. The median age was 54.5 years, and all were males (100.0%). Two cases (50.0%) were moderate, and one was mild and asymptomatic, respectively. Three cases (75.0%) had at least one comorbidity (brucellosis excluded). All 4 patients were found in COVID-19 nucleic acid screening. Case C and D had only headache and fever on admission, respectively. Four cases were treated with Traditional Chinese medicine, western medicines for three cases, no adverse reaction occurred during hospitalization. All patients were cured and discharged. Moreover, one case (25.0%) had still active brucellosis without re-positive COVID-19, and other three cases (75.0%) have no symptoms of discomfort except one case fell fatigue and anxious during the follow-up period after recovery. Conducting the literature review, two similar cases have been reported in two case reports, and were both recovered, whereas, no data of follow up after recovery. CONCLUSION These cases indicate that COVID-19 patients with brucellosis had favorable outcome before and after recovery. More clinical studies should be conducted to confirm our findings.

Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.
