Objective To explore EEG characteristics and the therapeutic effect in children with electrical status epilepticus during slow sleep(ESES).Methods The eligible ESES cases in our center from 2014 to 2020 were included.The age at diagnosis of ESES,the duration of ESES,spike wave index(SWI)during wakefulness and the distribution of spike wave during the period of ESES,age at seizure onset,the clinical syndromes and the outcomes after treatment were analyzed.The ESES cases were divided into 4 groups according to the distribution of spike wave:focal ESES,unilateral ESES,bilateral asymmetric ESES,multiple foci ESES.The SWI during the awake stage were divided into 3 groups based on the different rates:≤20%,21%～49%,≥50%.The therapeutic outcomes were classified into three groups:satisfactory response,seizure control and ineffective.Results 50 cases were included,with 32 males and 18 females.The average onset age of ESES was 6 years and 7 months,and the average duration of ESES was 28 months.A significant correlation between the distribution of ESES and the thera-peutic effects was found,bilateral asymmetric ESES had a good therapeutic effects,while multiple foci ESES showed a poor therapeutic effects.The duration of ESES was significantly correlated with therapeutic effects,and the efficacy was worse when the duration was longer than 1 year.A significant relationship between the SWI during wakefulness of ESES and the therapeutic effects was detected,the patient with SWI≤20%during wakefulness had a good therapeutic effect.There was a negative correlation between the onset age of ESES and the duration of ESES and SWI index during wakefulness.There was a positive correlation between the duration of ESES and SWI index during wakefulness.Conclusion Our results suggest that onset age,distribution,duration and SWI during wake-fulness of ESES were correlated with therapeutic outcomes,The patient with SWI≤20%during wakefulness had a good therapeutic effect and have unfavorable outcomes with ESES last more than 1 year.The earlier onset of ESES,the longer duration of ESES and higher SWI during wakefulness will be showed..

Rheumatoid arthritis(RA)is an autoimmune disease with the basic pathological manifestation of synovial inflammation.Symmetric poly-articular pain and swelling are the main symptoms in clinical practice,and even extra-articular manifestations and comorbidities such as interstitial fibrosis and coronary artery disease are triggered,which seriously affect the quality of life of patients.Traditional Chinese medicine(TCM)has achieved good clinical efficacy in the prevention and treatment of RA with the advantages of multi-pathway,multi-target,multi-component,and less toxic side effects,and plays an important role in the treatment of RA.Recently,many studies have demonstrated that Chinese medicine monomers and Chinese herbal compound can control inflammation,reduce angiogenesis,induce apoptosis of synovial fibroblasts,and inhibit their proliferation,invasion and migration by regulating the PI3K/Akt signaling pathway,so as to play a key role in the treatment of RA.For this reason,the article summarizes current knowledge regarding the PI3K/Akt signaling pathway and its role in RA,as well as summarizes the current research progress of TCM in the treatment of RA by regulating the PI3K/Akt signaling pathway.The aim of this review is to provide theoretical bases for the prevention and treatment of RA and the development of new drugs.

Ankylosing spondylitis(AS)is a typical spinal arthritis characterised by inflammatory back pain,which seriously affects the health and quality of life of patients.The clinical efficacy of Chinese medicine in the treatment of ankylosing spondylitis is clear,but the mechanism is not clear,and the existing animal models cannot be well applied to the evaluation of Chinese medicine in the treatment of ankylosing spondylitis.Therefore,this paper summarizes the existing animal models based on Chinese and Western medicine clinical diagnosis,disease characteristics,etiology and Chinese medicine evidence,and finds that among the existing animal models,the proteoglycan-induced arthritis mouse model has a higher Chinese and Western medicine clinical fit than the other models,but lacks the corresponding Chinese medicine evidence model evaluation.The other animal models had a higher Western clinical match,but lacked the characteristics of the Traditional Chinee Medicine(TCM)syndrome.As ankylosing spondylitis is a chronic inflammatory autoimmune disease with complex pathogenic factors,the existing animal models cannot better simulate the clinical symptoms.Therefore,the establishment of animal models of ankylosing spondylitis with the characteristics of Chinese and Western clinical evidence is a future research priority for AS TCM.

AIM:To investigate the inhibitory ef-fect of Zushima ointment on inflammation and bone destruction in CIA mice.METHODS:SPF grade male DBA/1 mice were used,6 were random-ly selected as the normal group,and 18 CIA mice that were successfully modelled were randomly di-vided into the model group,the plaster group(1.0 g/kg),and the fuselage group(0.12 g per time)ac-cording to the random number table method,6 mice in each group,and each administered group was given medication according to the body mass,and saline was given to both the normal and model groups.The normal group and the model group were given saline,and breathable adhesive paper was applied once a day for 4 h/session for 4 consec-utive weeks.The arthritis scoring index was used to observe the changes of arthritis symptoms and ar-thritis index scores of mice in each group.Micro-CT was used to observe the damage of hind paw of mice,real-time fluorescence PCR was used to de-tect the mRNA expression of IL-17,IL-1β and TNF-αin ankle joint tissues,and immunohistochemistry was used to detect the expression of OPG and RANKL proteins in ankle joint tissues,and hematox-ylin-eosin(HE)staining was used to observe the pathological changes of synovial tissues after the treatment.The pathological changes of synovial tis-sue were observed after hematoxylin-eosin(HE)staining,and the changes of osteoclasts in ankle joint tissue were observed by anti-tartaric acid phosphatase(TRAP)method.RESULTS:Compared with the normal group,the arthritis index score of the model mice was significantly higher(P＜0.05).Micro-CT showed severe bone erosion in the hind paws of the mice,destruction of the bone surface and reduction of bone volume.The expression of IL-17,IL-1β and TNF-α mRNA(PCR)in the ankle joint tissues was significantly higher(P＜0.05).Im-munohistochemistry showed that the relative ex-pression of OPG protein in the ankle joint tissues was reduced(P＜0.05).Immunohistochemistry showed a decrease in the relative expression of OPG protein(P＜0.01)and an increase in the rela-tive expression of RANKL protein(P＜0.01).HE re-sults showed moderate inflammatory cell infiltra-tion,swelling of synovial cells,massive formation of vascular opacities and synovial hyperplasia;an increase in the number of osteoclasts,roughness of the surface of articular cartilage tissue,severe bone destruction and thinning of the cartilage lay-er.Compared with the model group,the arthritic symptoms of mice in the cream group and the futa-lin group were relieved and the arthritis index score was reduced;the bone density of the mice's hind paws improved,effectively relieving osteopo-rosis;the expression of IL-17,IL-1β and TNF-αmRNA(PCR)in the ankle joint tissue was signifi-cantly reduced(P＜0.05);the immunohistochemical results showed that the relative expression of OPG protein was increased(P＜0.05),the relative expres-sion of RANKL protein decreased(P＜0.01).HE re-sults showed that synovial cell enlargement was significantly improved,mild inflammatory cell infil-tration,synovial hyperplasia was not obvious;the number of broken bone was reduced,articular car-tilage destruction was significantly improved and relieved,and the thickness of cartilage layer was significantly increased.CONCLUSION:Ancestral hemp poultice relieves local symptoms of RA,re-duces the expression of inflammatory factors and attenuates the inflammatory response,possibly by inhibiting osteoclast differentiation and activation through modulation of the OPG/RANKL signalling axis,which further ameliorates the biological ef-fects of articular bone and cartilage destruction.

Osteoporosis (OP) is a prevalent metabolic bone disease with a complex pathogenesis that has not yet been fully elucidated. Recent studies have revealed that the Toll-like receptor 4 (TLR4) signaling pathway plays a significant role in the development and progression of OP. TLR4, a crucial immune receptor primarily expressed in immune cells, is involved in inflammatory responses and immune regulation. The TLR4 signaling pathway influences bone metabolism and remodeling through multiple mechanisms. Therefore, investigating the role of the TLR4 signaling pathway in OP is of great significance for its prevention and treatment. Research targeting the TLR4 signaling pathway provides novel insights and approaches for OP therapy. Future studies should further explore the mechanisms of the TLR4 signaling pathway, develop therapeutic agents that modulate this pathway, and validate their efficacy in OP through clinical trials, thereby offering more options for the clinical management of OP.

Objective:Hepatocellular carcinoma (HCC) is the fourth most dominant cancer in the world and the second leading cause of cancer-related deaths in the China. With the increase in the incidence of metabolic syndrome (MS) in the population, the correlation between MS and HCC has gradually been recognized. MS manifests as non-alcoholic fatty liver disease (shortly known as NAFLD) in the liver. A large number of research results has shown that the development of fatty liver is closely related to the occurrence of HCC, in which lipid metabolism plays a key regulatory role, and lipid metabolism is regulated by fatty acid binding protein (FABP). This study signifies the lipid metabolism analysis and the key FABP expression conditions in HCC.Methods:Data of patients who were first diagnosed with primary HCC between January 2016 to July 2019 were collected, and were divided into two groups according to the etiology, namely the viral and non-viral hepatitis-related HCC group. The relationship between MS-related factors and HCC was analyzed by t-test and chi square test. The expressions of FABP1, FABP4 and FABP5 were detected in cancer and adjacent tissues by immunohistochemistry, and the expressions of FABP1, FABP4 and FABP5 in HCC with fatty liver were detected by immunofluorescence. Finally, the expressional characteristics of the above-mentioned FABPs in HCC patients were analyzed with different clinicopathological features.Results:There were statistically significant differences in the rate of abnormal lipid metabolism and the number of abnormalities in MS-related factors between the viral and non-viral hepatitis-related HCC group. FABP1, FABP4, and FABP5 expression in HCC tissues were lower than the corresponding adjacent tumor tissues. Compared with simple HCC, FABP1, FABP4, FABP5 expression were increased in HCC tissues with steatosis, and the expression of FABP was closely related to the clinical characteristics of patients.Conclusion:Abnormal lipid metabolism is closely related to non-viral hepatitis-related HCC. The expression of lipid metabolism regulatory proteins FABP1, FABP4, and FABP5 are down-regulated in HCC tissues, but up-regulated in HCC with fatty liver, suggesting that the relationship between MS, especially dyslipidemia, and HCC should be paid attention to in clinical practice for early intervention. FABP1, FABP4, FABP5 may regulate HCC occurrence and development.

Objective To investigate the effect of exercise diary on arm exercise compliance ofpatients with peripherally inserted centralcatheter (PICC). Methods Thirty patients with PICC hospitalized in our hospital from June to August in 2017 were selected as the control group, where the patients received guidance on functional exercises through arm exercise videos and routine methods. Another thirty-two patients hospitalized in our hospital from September to November of 2017 were selected as the observation group, where in addition to the same treatment as in the control group and these patients received interventions using their self-designed exercise diary for a total of 31 days. Their compliance with functional exercises before and after intervention and the incidences of venous thrombosis after intervention were compared between the two groups. Results After interventions, the compliance rate of arm exercises in the observation group was significantly higher than that of the control group (90.6% vs. 26.7%, P＜0.05). The incidence of venous thrombosis in the observation group was significantly lower than that of the control group (3.1% vs. 30.0% , P＜0.05). Conclusions Exercise diary can improve the arm exercise compliance of PICC patients and prevent the occurrence of venous thrombosis. It is worthy of clinical application and promotion.

To identify the related substances of fusidic acid by LC-MS,separation was performed on an Agilent Extend-C18column(150 mm ×4. 6 mm,3. 5 μm)by linear gradient elution with a mobile phase consisting of methanol,acetonitrile and formic acid. Electrospray positive ionization high resolution TOF/MS was used for the determination of the accurate mass and elemental composition of parent ions of the related substances;triple qua-drupole tandem mass was employed for the mass spectra determination of the product. The structures of the related substances were then figured out through the elucidation of the fragment ions. Fusidic acid and its related sub-stances were adequately separated under the established HPLC conditions. Nineteen major related substances of fusidic acid were detected and speculated by hyphenated techniques. Eleven of them were recorded in European Pharmacopoeia,while the others have not been previously reported. The established LC-MS method is effective for the separation and identification of the related substances of fusidic acid and the results are useful for its storage conditions and quality assurance.

Objective To investigate the establishment of focal cerebral ischemia model in rabbits with the improved suture method.Methods A total of 45 healthy and clean adult New Zealand rabbits were divided into either a sham operation group (n =5) or a model group (n =40) using random number table method before modeling,and the sex was not limited.The self-made head ends of 2-0 fishing lines dipped in paraffin were used as the sutures.The external carotid artery was cut and inserted into a intracranial artery through the internal carotid artery and blocked the origin of middle cerebral artery.The neurological function score was performed after 6 h.The neurological deficit scores ≥2 was successful modeling.The rabbits were killed by anesthesia.The brain slices were stained with 2％ 2,3,5-triphenyl tetrazolium chloride solution.The infarct foci were observed.The diameters of suture head and the depth of suture insertion were compared in the model rabbits with successful modeling,failure,and death in the model group.Results There were 40 rabbits in the model group,six of them died,including 4 died of subarachnoid hemorrhage within 4 h after operation,and 2 died from anesthetic accident.The mortality rate was 15.0％.Seven rabbits failed,mainly because of cerebral vasospasm and the insertion depth of suture was insufficient.Twenty-seven had successful modeling,and the success rate was 67.5％.All the rabbits in the sham operation group survived.The diameter of the suture head and insertion depth in the successful modeling rabbits were compared with the death and failure outcome in rabbits.The difference was statistically significant (diameter:0.52 ± 0.14 mm vs.0.45 ±0.40 mm and 0.58 ±0.17 mm;depth:5.49 ±0.17 cm vs.6.04 ± 0.11 cm and 4.26 ±0.30 cm;all P ＜ 0.05).Conclusions The improved suture method can successfully prepare the focal cerebral ischemia model of middle cerebral artery in rabbits.The method is simple.Its repeatability and practicability are better.
