ObjectiveTo construct a family-centered care model for children with tuberculosis based on the double ABC-X model, and to evaluate its clinical effects. MethodsFrom December 2022 to October 2023, 64 newly admitted children with tuberculosis who met the criteria and their caregivers were recruited from the tuberculosis department of Shanghai Public Health Clinical Center were randomly divided into an experimental group (32 cases) and a control group (32 cases).The control group was given a conventional health care, while the experimental group was given a family-centered health care intervention based on the double ABC-X model, in which a multidisciplinary care team provided personalized information and emotional support for the caregivers and their children. Medication adherence of the children, caregiver’s teading burden, and disease management competence were compared between the 2 groups. ResultsA total of 29 cases in the experimental group and 27 cases in the control group completed the intervention. At 12 weeks of intervention, the medication adherence score (7.72±0.45 vs 7.41±0.50, P<0.05) and disease management competence score (36.97±7.85 vs 31.56±7.30, P<0.05) were higher in the experimental group than that in the control group while the caregiving burden score (31.79±13.40 vs 40.04±9.01, P<0.05) and difficulty of disease management score (30.41±12.41 vs 38.56±9.48, P<0.05) were lower than that in the control group. At 24 weeks of intervention, the medication adherence score (7.34±0.97 vs 6.70±1.14, P<0.05) and disease management competence score (42.07±6.93 vs 35.63±7.32, P<0.05) were higher in the experimental group than that in the control group as well, but the caregiving burden score (31.62±11.72 vs 39.63±10.17, P<0.05) and difficulty of disease management score (30.59±10.87 vs 37.81±9.32, P<0.05) were lower than that in the control group. ConclusionFamily-centered care based on the double ABC-X model can effectively promote medication adherence among children with tuberculosis, reduce caregivers’ care burden and disease management difficulties, and improve caregiver’s disease management competence.

Objective To investigate the effect of aqueous extract of Scrophularia ningpoensis(AESN)on AMP-activated protein kinase(AMPK)activity in INS-1 cells under high glucose(HG)conditions.Methods INS-1 cells were cultured in HG medium and treated with different concentrations of AESN.The influences of AESN on cell viability and pyroptotic body formation were detected using the CCK-8 assay.Western blotting was used to observe the effects of AESN on AMPK expression and phosphorylation.The effect of AESN on AMPK activity was measured using time-resolved fluorescence resonance energy transfer(TR-FRET)assay.Results Compared with normal glucose controls,INS-1 cells exposed to HG showed decreased cell viabilities and increased formation of pyroptotic bubbles using CCK-8 assay.Western blotting results indicated that HG exposure led to a decrease in intracellular AMPK phosphorylation levels.However,co-incubation with AESN under HG exposure AESN treatment increased the cell viabilities and phosphorylation of AMPK and decreased the pyroptotic bubbles formation in a concentration-dependent manner.In addition,the results of TR-FRET revealed that AESN treatment effectively increased AMPK activity in a concentration-dependent manner.Conclusion AESN has an activating effect on AMPK activity in HG-treated INS-1 cells.

Objective To investigate the relationship among circulating soluble major histocompatibility complex class Ⅰ-related chain A(sMICA),soluble major histocompatibility complex class Ⅰ-related chain B(sMICB),the activity of systemic lupus erythematosus(SLE)and autoantibodies.Methods A total of 156 SLE patients(SLE group)and 103 healthy volunteers(control group)who underwent physical examination in outpatient physical examination center were selected from the Qianjiang Hospital Affiliated to Chongqing University from January 2020 to January 2023.According to SLE disease activity score(SLEDAI),these SLE patients were divided into mild activity group(n=43),moderate activity group(n=69),and severe activity group(n=44).Serum levels of sMICA and sMICB,and the proportion of autoantibodies and peripheral blood NK cells were detected.Spearman or Pearson method was used to analyze the correlation among sMICA,sMICB,score,autoantibodies and peripheral blood NK cells proportion.Receiver operating characteristics(ROC)curve was used to evaluate the value of sMICA and sMICB in the diagnosis of SLE activity.Results Serum sMICA(173.65±23.92 pg/ml)and sMICB(96.35±15.74 pg/ml)levels in SLE group were higher than those in control group(32.51±6.27 pg/ml,12.03±2.47 pg/ml),while the proportion of CD3-CD56+NK cells(12.02％±2.65％)in peripheral blood was lower than that in control group(18.35％±3.71％),and the differences were statistically significant(t=58.498,53.897,-16.010,all P＜0.05).Serum sMICA and sMICB levels in severe active group were higher than those in moderately active group and mildly active group(t=8.192,12.352;19.652,23.742,all P＜0.05),and the proportion of CD3-CD56+NK cells in peripheral blood was lower than that in moderate and mild active groups(t=8.154,10.658,P＜0.05).The differences in positive rates of anti-dsDNA antibody,anti-nuclear antibody,anti-nucleosome antibody and anti-histone antibody in SLE patients with different disease activities were significant(x2=8.795,7.216,7.539,8.946,all P＜0.05).Serum sMICA and sMICB levels in SLE patients were positively correlated with SLED AI score,anti-dsDNA antibody,anti-nuclear antibody,anti-nucleosome antibody and anti-histone antibody(r=0.206～0.402,all P＜0.05),and negatively correlated with the proportion of CD3-CD56+NK cells in peripheral blood(r=-0.563,-0.427,all P＜0.05).The areas under the curve of SLE in severe active group diagnosed by sMICA and sMICB alone were 0.652 and 0.704,respectively.The area under the curve of SLE in severe active group diagnosed by sMICA and sMICB combined with SLE was 0.812,which was higher than that by the single diagnosis(Z=3.050,2.346,all P＜0.05).Conclusion The increased serum sMICA and sMICB levels in SLE patients were associated with the increased positive rate of SLE autoantibodies,the decreased proportion of NK cells in peripheral blood and the enhanced disease activity,which could be used as potential markers of SLE.

【Objective】 To investigate the quality of cryoprecipitates prepared from buffy coat-derived plasma of fresh whole blood at room temperature 20℃-24℃ isolated at different time periods, explore the optimal time for preparing cryoprecipitates, so as to improve the utilization rate of blood. 【Methods】 A total of 250 bags of whole blood collected by CPDA-1 and stored at 20℃-24℃ from October 2020 to December 2020 were randomly selected as the experimental group, and divided into groups A1 (0-8 h), A2 (8-10 h), A3 (10-12 h), A4 (12-14 h) and A5 (14-16 h) (with 50 bags in each group) according to the preparation time point. The upper-buff-coat plasma was separated and quickly frozen as the source for cryoprecipitates. Meanwhile, another 50 bags of fresh frozen plasma prepared within 0-16h after routine storage at 2℃-6℃ were randomly selected as the control group (group B), which was used as the raw plasma to make cryoprecipitate. Coagulation factor Ⅷ (Ⅷ factor) and fibrinogen (FIB) were detected, and the effect of different preparation time and different storage temperature on the content of factor Ⅷ and FIB and the pass rate were compared. 【Results】 In comparison to the control group, the Ⅷ factor content of groups A4 and A5 was significantly decreased, and the differences between groups A4, A5 and B were statistically significant (P<0.001). There was no statistically significant difference in the effect of preparation of buffy coat-derived plasma on the FIB quality of cryoprecipitate in different time periods (P>0.05). The Factor Ⅷ content ≥60 IU/ bag prepared from buffy coat-derived plasma accounted for 96.4% (1.5 U) in the experimental group. 【Conclusion】 The buffy coat-derived plasma prepared within 12 h at 20℃-24℃ is suitable for preparing 2 U cryoprecipitate coagulation factor, while that prepared within 12-16 h is suitable for preparing 1.5 U cryoprecipitate coagulation factor.

Sudden unexpected death in epilepsy(SUDEP)is the leading cause of accidental death in epileptic patients.The postictal generalized EEG suppression(PGES)is related to SUDEP.The age,seizure type,tonic seizure/tonic muscle contraction,ictal and post-ictal respiratory dysfunction and autonomic dysregulation is associated with PGES with significant individual variation.Progressive slowing of clonic phase(PSCP)in generalized tonic-clonic seizures(GTCS)is an independent predictor of the onset and prolongation of PGES.

Grape (Vitis vinifera L.) in production is frequently exposed to inadequate light, which significantly affects its agronomic traits via inhibiting their physiological, metabolic and developmental processes. To explore the mechanism how the grape plants respond to the weak light stress, we used 'Yinhong' grape and examined their physiology-biochemistry characteristics and transcriptional profile under different levels of weak light stress. The results showed that grape seedlings upon low intensity shading treatments were not significantly affected. As the shading stress intensity was strengthened, the epidermis cells, palisade tissue, and spongy tissue in the leaves were thinner, the intercellular space between the palisade tissue and spongy tissue was larger compared with that of the control, and the activities of superoxide dismutase, catalase and peroxidase were decreased gradually. Additionally, the soluble protein content increased and the free proline content decreased gradually. Compared with the control, significant changes in plant photosynthetic characteristics and physiology-biochemistry characteristics were observed under high intensity of shading (80%). RNA-seq data showed that the differentially expressed genes between CK and T2, CK and T4, T2 and T4 were 13 913, 13 293 and 14 943, respectively. Most of the enrichment pathways were closely related with the plant's response to stress. Several signaling pathways in response to stress-resistance, e.g. JA/MYC2 pathway and MAPK signal pathway, were activated under weak light stress. The expression level of a variety of genes related to antioxidation (such as polyphenol oxidase and thioredoxin), photosynthesis (such as phytochrome) was altered under weak light stress, indicating that 'Yinhong' grape may activate the antioxidation related pathways to cope with reactive oxygen species (ROS). In addition, it may activate the expression of photosynthetic pigment and light reaction structural protein to maintain the photosynthesis activity. This research may help better understand the relevant physiological response mechanism and facilitate cultivation of grape seedlings under weak light.
