Objective: To construct an evaluation index system of cervical cancer prevention and control literacy, so as to provide an assessment tool for cervical cancer prevention and control literacy. Methods: The preliminary framework for cervical cancer prevention and control literacy was designed based on literature review. Twenty-one experts with both theoretical and practical experience in cervical cancer prevention and control were invited to participate in two rounds of Delphi consultation. The weights of indicators were determined by the percentage weighting method and product method, and the response rate, authority level, opinion concentration degree, and coordination degree of experts were evaluated. Results: Twenty-one experts participated in the consultation, including 3 males and 18 females. There were 11 experts with a doctor's degree, 7 with a master's degree and 3 with a bachelor's degree. All of them had senior professional titles and had more than 10 years of working experience. The recovery rates of the two rounds of consultations were 100.00% and 95.24%, the authority coefficients were 0.963 and 0.948, and Kendall's coefficients of concordance were 0.175 and 0.148 (both P<0.05), respectively. The final cervical cancer prevention and control literacy evaluation index system included 3 primary indicators (basic knowledge and concepts: 0.334; healthy lifestyle and behaviors: 0.338; basic skills: 0.328), 12 secondary indicators, with "capability to accurately acquire, comprehend, evaluate and apply health information" having the highest weight (0.166), and 51 tertiary indicators, with "HPV vaccination" (0.086), "consulting on relevant issues" (0.082), and "expressing personal perspectives" (0.080) having relatively higher weights. Conclusion The evaluation index system of cervical cancer prevention and control literacy serves as a valid assessment tool for women of appropriate age, providing the reference for developing targeted health education to enhance cervical cancer prevention and control literacy.

OBJECTIVE: To analyze the rules of moxibustion for low back pain by ZHOU Meisheng by using data mining and knowledge graph technology. METHODS: Taking the medical cases of moxibustion for low back pain from ZHOU Meisheng's legacy manuscripts and existing works as the research objects, information on disease types, symptoms, tongue manifestations, pulse conditions, syndrome patterns, moxibustion methods and acupoints were collected.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Grooming,as an evolutionarily conserved repetitive behavior,is common in various animals,including humans,and serves essential functions including,but not limited to,hygiene maintenance,thermoregulation,de-arousal,stress reduction,and social behaviors.In rodents,grooming involves a patterned and sequenced structure,known as the syntactic chain with four phases that comprise repeated stereotyped movements happening in a cephalocaudal progression style,beginning from the nose to the face,to the head,and finally ending with body licking.The context-dependent occurrence of grooming behavior indicates its adaptive significance.This review briefly summarizes the neural substrates responsible for rodent grooming behavior and explores its relevance in rodent models of neuropsychiatric disorders and neurodegenerative diseases with aberrant grooming phenotypes.We further emphasize the utility of rodent grooming as a reliable measure of repetitive behavior in neuropsychiatric models,holding promise for translational psychiatry.Herein,we mainly focus on rodent self-grooming.Allogrooming(grooming being applied on one animal by its conspecifics via licking or carefully nibbling)and heterogrooming(a form of grooming behavior directing towards another animal,which occurs in other contexts,such as maternal,sexual,aggressive,or social behaviors)are not covered due to space constraints.

BACKGROUND:Cerebral ischemic stroke is one of the main fatal and disabling diseases in the clinic,but only a few patients benefit from vascular recanalization in time,so it is urgent to explore new and effective therapy.As one of the critical pathological changes of ischemic stroke,the glial scar formed mainly by astrocytes is one major cause that hinders axonal regeneration and neurological recovery at the late stage of stroke. OBJECTIVE:To elucidate the pathological process and crucial signal regulatory mechanism of astrocytes in the formation of glial scar after ischemic stroke,as well as the potential therapeutic targets,to provide a theoretical reference for intervening astrocytic scar formation against ischemic stroke effectively,and novel strategies for promoting post-stroke rehabilitation. METHODS:The relevant articles published in CNKI,PubMed and Web of Science databases from 2010 to 2022 were retrieved.The search terms were"Ischemic stroke,Brain ischemi*,Cerebral ischemi*,Astrocyt*,Astroglia*,Glial scar,Gliosis,Astrogliosis"in Chinese and English.Finally,78 articles were included after screening and summarized. RESULTS AND CONCLUSION:(1)Astrocytes play an important role in the maintenance of central nervous system homeostasis.After ischemic stroke,astrocytes change from a resting state to an active state.According to the different severities of cerebral ischemic injury,astrocyte activation changes dynamically from swelling and proliferation to glial scar formation.(2)Mature astrocytes are stimulated to restart the cell cycle,then proliferate and migrate to lesions,which is the main source of the glial scar.Neural stem cells in the subventricular zone,neuron-glial antigen 2 precursor cells and ependymal precursor cells in the brain parenchyma can also differentiate into astrocytes.Endothelin-1,aquaporin 4,ciliary neurotrophic factor and connexins are involved in this process.In addition,chondroitin sulfate proteoglycan,as the main component of the extracellular matrix,forms the dense glial scar barrier with proliferated astrocytes,which hinders the polarization and extension of axons.(3)Activation or inhibition of crucial signal molecules involved in astrocyte activation,proliferation,migration and pro-inflammation functions regulate the glial scar formation.Transforming growth factor beta 1/Smad and Janus kinase/signal transducer and activator of transcription 3 are classical pathways related to astrogliosis,while receptor-interacting protein 1 kinase and glycogen synthase kinase 3β are significant molecules regulating the inflammatory response.However,there are relatively few studies on Smad ubiquitination regulatory factor 2 and Interleukin-17 and their downstream signaling pathways in glial scar formation,which are worthy of further exploration.(4)Drugs targeting astrogliosis-related signaling pathways,cell proliferation regulatory proteins and inflammatory factors effectively inhibit the formation of glial scar after cerebral ischemic stroke.Among them,the role of commonly used clinical drugs such as melatonin and valproic acid in regulating glial scar formation has been verified,which makes it possible to use drugs that inhibit glial scar formation to promote the recovery of neurological function in patients with stroke.(5)Considering the protective effects of glial scar in the acute phase,how to choose the appropriate intervention chance of drugs to maintain the protective effect of the glial scar while promoting nerve regeneration and repair in the local microenvironment is the direction of future efforts.

Objective To compare image quality of turbo spin echo(TSE)diffusion tensor imaging(DTI)and echo planar imaging(EPI)DTI for displaying temporal lobe radiation encephalopathy(REP).Methods Thirty nasopharyngeal carcinoma patients with suspected REP disease progression were prospectively enrolled.Subjective evaluation of image sharpness,susceptibility artifacts and deformation of TSE-DTI and EPI-DTI was performed using a 5-point scale,while objective evaluation aimed on the mean diffusion coefficient(MD),fractional anisotropic(FA),signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR)and distortion ratio(DR)were carried on.Results The susceptibility artifacts and deformation scores of TSE-DTI were higher than that of EPI-DTI(P＜0.001).FA of REP edge and normal brain tissue were lower than those of EPI-DTI,with SNR and CNR higher than those of EPI-DTI(both P＜0.001).DR of REP lesions and bilateral temporal lobes were lower than those of EPI-DTI(all P＜0.001).Conclusion Compared with EPI-DTI,TSE-DTI could significantly improve image quality for displaying REP by reducing susceptibility artifacts and deformation of images.

SARS-CoV-2 may have potential effects on the male reproductive system. Evidence has shown that SARS-CoV-2 is not likely to transmit through sexual intercouse. However, male infected with SARS-CoV-2 may experience sexual dysfunction, semen quality decline, testicular damage and abnormal sex hormones. The extent and duration of these damages are still unclear, and further multidimensional research is necessary.

Objective:To investigate the efficacy and safety of cedilanid in the treatment of severe pneumonia in infants and the value of preventing heart failure.Methods:A total of 80 children with severe pneumonia admitted to Dezhou Maternal and Child Health Hospital from January 2019 to December 2020 were selected and randomly divided into the control group and the observation group, with 40 cases in each group. The control group received comprehensive treatment, while the observation group was treated with cedilanid (0.01 mg/kg, one-time intravenous injection) on the basis of the control group. The efficacy of both groups was observed after 5 d of treatment. The incidence of heart failure, correction time of heart failure, improvement time of symptoms and signs, and length of hospitalization time were compared between the two groups; the inflammatory markers, myocardial markers and arterial blood gas indexes were compared between the two groups before and after the treatment.Results:The total effective rate in the observation group was higher than that in the control group, and the incidence of heart failure in the observation group was lower than that in the control group: 90.0% (36/40) vs. 72.5% (29/40), 32.5%(13/40) vs. 10.0%(4/40), the differences were statistically significant ( χ2 = 4.02, 4.10, P<0.05). The improvement time of symptoms and signs (restlessness elimination, respiratory improvement, heart rate improvement and disappearance of rhonchus in lung) in the observation group were less than those in the control group ( P<0.05). The levels of procalcitonin (PCT) and N-terminal pro-brain natriuretic peptide (NT-ProBNP), myocardial troponin I(cTnI), and creatine kinase isoenzyme (CK-MB) in the observation group after treatment were lower than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. The levels of oxygen partial pressure (PaO 2), blood oxygen saturation (SaO 2) and oxygenation index (PaO 2/FiO 2) in the observation group after treatment were higher than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. Conclusions:Early application of small dose of cedilanid in infants with severe pneumonia can effectively reduce the occurrence of heart failure, improve the clinical symptoms and blood gas indicators, with significant curative effect, which is worthy of promotion.
