Sleep disorder is a common complication in elderly patients with cerebral infarction, which seriously affects the rehabilitation process and quality of life of patients. Currently, the treatment of sleep disorders mainly consists of pharmacological and non-pharmacological interventions. Although pharmacological treatment has a certain effect, there are many adverse reactions, especially for elderly patients with declining body function, whose use carries a higher risk. It is of great significance to develop a reasonable individualized non-pharmacological intervention to prevent and treat the accompanying sleep disorders after cerebral infarction. This paper provides a brief review of present status, influencing factors and non-pharmacological interventions of sleep disorders in patients with acute cerebral infarction.

Objective To verify the accuracy of γ spectrometry by analyzing the results of national interlaboratory comparisons of radionuclide analysis by γ spectrometry from 2018 to 2023. Methods A statistical analysis was conducted on the results from multiple years of participation in the national interlaboratory comparisons of radionuclide analysis by γ spectrometry. The measurement results of radionuclide specific activities in soil were analyzed to provide technical support for improving the capability to analyze radionuclides in soil. Results The laboratory participated in six interlaboratory comparisons and conducted 23 radionuclide analyses by γ spectrometry from 2018 to 2023. The relative deviation was −12.20% to 8.11%, the |Z_test| was 0 to 0.61, the U_test was 0 to 0.62, and the U_rel was 0.07 to 0.12. The overall pass rate was 100% and the excellent rate was 33.3%. In addition, 21 of the 23 (91.3%) radionuclide analyses showed full scores in experiment operation. However, the total scores were relatively low due to multiple oversights and lack of rigor in the preparation of the test reports, which prevented the laboratory from qualifying for the excellence evaluation process, resulting in a relatively low excellent rate. Conclusion The interlaboratory comparisons indicate that the measurements of radionuclides in this laboratory were all qualified, with full scores for experiment operation in several analyses. These results demonstrate that the soil radionuclide analysis system based on γ spectrometry is reliable and stable.

OBJECTIVE To observe the effects of Panax quinquefolium-Acorus calamus on learning and memory abilities in diabetes mellitus(DM) mice and investigate the mechanism of Panax quinquefolium-Acorus calamus in treating diabetic cognitive impairment(DCI) through network pharmacology and animal experiments. METHODS Diabetic mouse model was established by intraperitoneal injection of streptozotocin(80 mg·kg−1), followed by 8 weeks of oral administration and assessment of drug efficacy using the Morris water maze. The active ingredients and targets of Panax quinquefolium-Acorus calamus were collected using TCMSP, Swiss Target Prediction, and Gene Cards. The protein-protein interaction network of "Traditional Chinese Medicine-Ingredient-Disease targets" was constructed using the String platform and Cytoscape, visualized, and subjected to enrichment analysis using the Metascape database. The anti-DCI mechanism of Panax quinquefolium-Acorus calamus was examined through ELISA and Western blotting, while changes in hippocampal neurons of diabetic mice were observed using HE staining. RESULTS Panax quinquefolium-Acorus calamus reduced the escape latency of diabetic mice(P<0.05), without significant impact on swimming speed. Network pharmacology results indicated that the main components of Panax quinquefolium-Acorus calamus in treating DCI were ginsenoside Re, ginsenoside Rh2, and shanjin phenol, which regulated the Nrf2-Keap1 signaling pathway to treat DCI. Animal experiments demonstrated that Panax quinquefolium-Acorus calamus increased SOD activity(P<0.05), decreased MDA levels(P<0.01), enhanced the expression of HO-1, Keap1, Nrf2 in mouse brain(P<0.01), and alleviated the loosening of granule cell arrangement and nuclear condensation in the hippocampal CA1, CA3, and DG regions. CONCLUSION Using animal experiments combined with network pharmacology, this study preliminarily elucidates the potential targets and mechanisms of Panax quinquefolium-Acorus calamus in intervening DCI, and predictes the molecular basis for its intervention in DCI through molecular docking, providing insights for further in-depth research on Panax quinquefolium-Acorus calamus.

As population aging progresses,musculoskeletal health will serve as one of the most important indicators of health status in older adults.Studies related to the promotion of vitamin D absorption by drugs are now more common,but the drugs are accompanied by subsequent side effects.Notably,several non-pharmacological therapies are also being investigated for their respective effects on promoting vitamin D absorption.The purpose of this paper is to analyze the mechanism of vitamin D in osteoporosis,and to discuss the progress of research on the promotion of vitamin D absorption by acupuncture,tui na and acupuncture point burial,as well as by sunlight,diet,aerobic exercise,tai chi and aerobics,in order to provide a reference for clinical and scientific research on the selection of appropriate methods to promote vitamin D absorption.At the same time,it provides a non-pharmacological way to control bone loss for people with long-term home bone loss and osteoporosis.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.

We reported a case of microcephaly-capillary malformation(MIC-CAP)caused by STAMBP gene variant,in order to improve the clinical diagnosis and treatment.The patient is a 3-month-old male with recurrent convulsions and the main clinical manifestations are multiple forms of seizures,microcephaly,multiple small capillary malformations in the skin,and generalized hypotonia.The genetic test showed that a heterozygous variant in the STAMBP gene was present in the child.Both parents were heterozygous carriers.He was administrated various anti-seizure medications and ketogenic diet,but still had frequent seizures.He then underwent corpus callosotomy,and was followed up until he was 4 years and 10 months old.The post operational outcome was grade IV on Engel's classification.Based on the clinical data of 22 patients in literature,in addition to severe psychomotor retardation,microcephaly,and cutaneous capillary malformations,early-onset drug-refractory epilepsy is also a major feature of MIC-CAP syndrome,which is clinically rare and has a poor prognosis;Callosotomy may help to reduce seizures in the short term.However,the long-term outcome is poor.STAMBP gene is the main responsible gene for this syndrome.

Objective The purpose of this study was to examine effects of Isopsoralen on the osteoblast proliferation and differentiation and find its possible molecular mechanisms for anti-osteoporosis.Methods OCT-1 cells were cultured with common methods.While growing well,cells were cultured with 3 doses(10 μg·mL-1,30u μg·mL-1 and 60 μg·mL-1)of Isopsoralen for 48 h,or with purified bone morphogenetic protein 2(BMP2)protein(50 ng·mL-1).We first determined the effect of Isopsoralen on cell proliferation by MTT assay.The real time RT-PCR was also used to quantify changes in the mRNA levels of several genes,such as BMP2,Runt-related transcription factor 2(Runx2),and Osterix(Osx).We also used the Western blot analysis to evaluate the expression of Runx2 and Osx proteins.At last we used the BMP2loxp/loxp mice to isolate the primary calvaria osteoblasts,cultured with Isopsoralen of the best dose for 48 h after the in vitro conditional gene knockout technology,and tested the gene expressions of Runx2 and Osx.And the alkaline Phosphatase(ALP)staining was also performed.Result Isopsoralen(10 μg·mL-1)can promote osteoblast proliferation obviously.From the real time RT-PCR analysis,Isopsoralen can enhance the BMP2 mRNA levels,the effect of 10 μg·mL-1 was the best,and 30 μg·mL-1 followed.In addition,we found that Isopsoralen(10 μg·mL-1)can enhance the Runx2 mRNA levels significantly.We also found that lower doses of Isopsoralen can enhance the Osx mRNA levels,the effect of 30 μg·mL-1 was the best,and 10 μg·mL-1 followed.From the Western blot analysis,low doses of Isopsoralen(10 μg·mL-1 and 30 μg·mL-1)can stimulate the expression of Runx2 protein.Besides,three doses of Isopsoralen can stimulate the expression of Osx protein,and the effect of 10 μg·mL-1 and 30 μg·mL-1 are better.Finally,the results of in vitro conditional gene knockout experiment showed that the overexpression of Runx2 and Osx genes in osteoblasts,as well as ALP staining,induced by Isopsoralen are BMP2 dependent.Conclusions In this study,we firstly demonstrate that Isopsoralen can stimulate osteoblast proliferation and differentiation by mediating BMP2/Runx2/Osx signaling pathway.
