Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

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.

Aim To clarify the differential proteins of mammary tissues in Xihuang pills(XHP)against hy-perplasia of mammary glands(HMG)based on quanti-tative proteomics technology and validate them,and to explore the mechanism of action.Methods SD rats were randomly divided into blank group,model group and XHP group,with 10 rats in each group.Except for the blank group,estrogen and progesterone were injec-ted intramuscularly to establish a rat model of mamma-ry hyperplasia for 30 d.After XHP was administered for 14 d,the rats in each group were observed to have morphological changes in the apparent morphology of the mammary tissues,and pathological changes in the mammary tissues were stained with hematoxylin-eosin staining(HE),and the differentially expressed pro-teins(DEPs)in the groups were screened by quantita-tive proteomics technology and subjected to bioinforma-tics analysis,and Western blot to verify the key DEPs.Results Compared with the model group,the appar-ent pathological morphology of the XHP group was sig-nificantly improved,the diameter of the nipple height of the rats was significantly reduced(P＜0.01),and the degree of histopathology was significantly allevia-ted.Quantitative proteomics identified 4,299 DEPs in mammary tissue,and bioinformatics analysis of 14 DEPs with consistent changes between the XHP group and the blank group relative to the model group re-vealed that they were related to the regulation of mus-cular systemic processes,regulation of muscle contrac-tion,DNA replication,and pre-initiation of DNA repli-cation.Western blot results showed that,compared with the model group,rat mammary tissue of the XHP group showed significantly lower levels of ACLY and ALDOC protein expression levels were significantly re-duced and BIN1 protein expression levels were signifi-cantly increased(P＜0.01).Conclusions XHP may exert its anti-mammary hyperplasia effect through the regulation of BIN1,ACLY and ALDOC protein lev-els,the regulation of DNA replication,the regulation of pre-initiation of DNA replication and muscular sys-temic processes,and the regulation of muscle contrac-tion.

NLRP3 can recruit proteins such as ASC and pro-caspase1 to form NLRP3 inflammasomes after being stimulated by pathogen and danger signals in vivo,and then induce pyropto-sis and promote the inflammatory reactions to maintain the home-ostasis.However,the overactivation of NLRP3 inflammasomes is closely related to many inflammatory and autoimmune diseases in humans.Targeted inhibition of NLRP3 inflammasomes can sig-nificantly inhibit inflammation and alleviate the relative symp-toms.Therefore,it is an important research direction for treating diseases of NLRP3 inflammasome that searching for effective in-hibitors targeting NLRP3 inflammasome activation and achieving clinical transformation.This review summarizes the latest re-search progress based on the sources of NLRP3 inflammasome inhibitors.

Objective To explore the clinical efficacy of high hip center technique total hip arthroplasty(THA)for CroweⅡ and Ⅲ developmental dysplasia of hip(DDH)and severe hip osteoarthritis(HOA).Methods From January 2018 to Jan-uary 2020,74 patients with Crowe type Ⅱ and Ⅲ DDH and severe HOA were admitted,and 37 cases of anatomical hip center reconstruction were taken as control group,including 7 males and 30 females,aged from 42 to 65 years old with an average of(58.40±4.98)years old,body mass index(BMI)ranged from 18 to 29 kg·m-2 with an average of(23.02±2.21)kg·m-2.Thirty-seven routine high hip center technical reconstruction were performed as study group,including 5 males and 32 females,aged from 41 to 65 years old with an average of(57.31±5.42)years old,BMI ranged from 18 to 29 kg·m-2 with an average of(23.14±2.07)kg·m-2.The patients presented with hip pain,limited function and range of motion,and gait instability before surgery.All patients underwent THA,the control group underwent intraoperative anatomical hip center reconstruction,and the study group underwent intraoperative high hip joint reconstruction.The perioperative indicators of the two groups were com-pared.The hip joint function,balance function and gait of the patients were evaluated before surgery,3 months,6 months,and 12 months after surgery.The length difference of both lower limbs,horizontal distance of rotation center,vertical distance of ro-tation center and femoral eccentricity were measured before operation and 1 year after operation.The incidence of complica-tions in the two groups during the operation and postoperative follow-up was counted.Results The operation time of the study group was shorter than that of the control group,and the intraoperative blood loss was less than that of the control group(P＜0.05).After 12-months follow-up,1 was lost to followvup in study group and 2 were lost to follow-up in control group.The Har-ris scores and Berg balance scale(BBS),pace,stride frequency and single step length in the study group were higher than those in the control group at 3 months and 6 months after operation(P＜0.05);there was no statistically significant difference between the two groups in the indexes 12 months after operation(P＞0.05).The vertical distance of the center of rotation of the study group was greater than that of the control group 12 months after operation(P＜0.05),and there was no significant difference in the length difference of the lower limbs,the horizontal distance of the center of rotation,and the femoral eccentricity between two groups(P＞0.05).There were no complications in either group.Conclusion The long-term effects of TH A in patients with DDH and severe HO A were similar between the two central hip reconstruction methods,and the safety was good,and the high hip central reconstruction technique could shorten the operation time and reduce the amount of intraoperative blood loss.At the same time,it has certain advantages in early recovery of hip joint function,balance function and walking function of patients.

Objective To explore the value of quantitative CT(QCT)for assessing complications of type 2 diabetes mellitus(T2DM).Methods Totally 220 T2DM patients were included and divided into uncomplicated group(n=40),mono-complicated group(n=84)and multi-complicated group(n=96).Bone mineral density(BMD)of L2—L4,as well as visceral adipose tissue(VAT)and subcutaneous adipose tissue(SAT)area were collected using QCT and compared among groups.The operator characteristic curves were drawn,and the area under the curves(AUC)were calculated to observe the value of QCT indicators and comprehensive model based on clinical indicators and QCT indicators for evaluating complications of T2DM.Decision curve analysis(DCA)and clinical impact curve(CIC)analysis were used to analyze the clinical application value of the comprehensive model.Results Significant differences of patients’age,lumbar BMDs and areas of VAT were found among 3 groups(all P＜0.05).The AUC of comprehensive model for differentiating uncomplicated group from mono-complicated group,uncomplicated group from multi-complicated group and mono-complicated group from multi-complicated group was 0.753,0.865,and 0.761,respectively,higher than that of BMD,VAT and SAT area(all P＜0.05).DCA and CIC analyses showed that comprehensive model yielded clinical benefits and had good clinical applicability for assessing complications of T2DM.Conclusion QCT was valuable for assessing complications of T2DM.

The epidemiology and etiology of three suspected cases of imported skin diphtheria infection in Fujian Province were investigated.Secretion samples of patients with skin damage were collected for isolation and culture of Corynebacterium diphtheriae.Biochemical identification and mass spectrum analysis of pure cultures of suspected C.diphtheriae were conduc-ted,the virulence-related genes,including diphtheria toxin reporter(dtxR),toxin A(toxA),and toxin B(toxB)were detec-ted,and multilocus sequence typing(MLST)was performed.All three cases had typical clinical manifestations of cutaneous diphtheria,and C.diphtheriae was isolated from the damaged skin.The virulence genes of two C.diphtheriae strains isolated from two cases were identified as dtxR(+),toxA(-),and toxB(-),and the MLST type was ST-703.The virulence genes of C.diphtheriae isolated from one case were identified as dtxR(+),toxA(+),toxB(+),and the MLST type was ST-248.There is an increased risk of diphtheria in Fujian Province.C.diphtheriae without diphtheria toxin genes can also cause skin diphtheria.

Objective:To compare the efficacy and clinical value of high-throughput sequencing(HTS)and Sanger sequencing in detecting ABL kinase domain mutations in patients with chronic myeloid leukemia(CML).Methods:A total of 198 samples of 147 CML patients from July 2017 to March 2021 in Henan Cancer Hospital were collected and underwent high-throughput sequencing and Sanger sequencing to detect the mutations in ABL kinase domain,and the relevant clinical data were collected for comparative analysis.Results:The proportion of total mutations and ≥ 2 mutations detected by high-throughput sequencing were significantly higher than those detected by Sanger sequencing(P=0.01;P=0.046).≥ 2 mutations were detected in 22 cases,of which 5 cases(22.7％)had compound mutations.High-throughput sequencing can detect low level mutations that cannot be detected by Sanger sequencing.In 198 samples,25(12.6％)were low level mutations,33(16.7％)were high level mutations and 10(5.1％)were mixed high and low level mutations.In the analysis of related clinical factors,the total mutation rate and the low level mutation rate in the optimal period,failure period and warning period were gradually increased(total mutation rate,P=0.016;low level mutation rate,P=0.005).The mutation rate of the samples with additional chromosomal abnormalities was also significantly increased(P=0.009).The mutation rate of patients who received first-and second-line treatment was significantly lower than that of patients who received third-or higher-line treatment(P=0.006).Analysis based on variant allele frequency(VAF)of the mutation site was helpful to visually evaluate the clonal evolution status of TKI-resistance CML cells.Conclusion:High-throughput sequencing is more sensitive and accurate than Sanger sequencing in mutation detection,which is helpful to accurately and visually evaluate TKI treatment response and optimize treatment strategy for CML.
