Objective:To provide a scoping review of domestic and international studies on the influencing factors of frailty in stroke inpatients, and to provide guidance for interventional studies on debility in stroke inpatients in China.Methods:A systematic search of domestic and international literature databases, including China National Knowledge Infrastructure, WanFang, VIP, China Biomedical Literature Database, PubMed, Web of Science, Embase, Cochrane Library, CINAHL was conducted about the status and its influencing factors of frailty in stroke inpatients. The retrieval time limit was from database establishment to November 23, 2023. The included literature was extracted, analyzed, and summarized according to the reporting specifications of the scope review guidelines.Results:Thirty-six articles were included, all of the 36 papers reported the prevalence of frailty in patients with stroke. The top three countries with the highest prevalence were China (15.3%-86.9%), the United Kingdom (28%-78%), and Italy (31.37%). The risk factors of stroke frailty were categorized mainly into 4 themes: social demographic factors, physical health factors, disease-related factors, and psychological and social background factors.Conclusions:The confidence of frailty in stroke patients of a higher level at home and abroad, and the risk factors involved are complex and diverse. It is suggested that future studies need to conduct large-sample, multicenter longitudinal studies to clarify the causal relationship, strengthen the exploration of controversial factors of stroke debility, and carry out more targeted intervention studies, so as to reduce the incidence of frailty and improve the recovery process of patients.

[Objective]To analyze the manipulation and acupoint selection rules of Tuina treatment for adolescent idiopathic scoliosis(AIS).[Methods]Clinical research literature on Tuina treatment for AIS was searched in databases such as China National Knowledge Infrastructure(CNKI),VIP Database,WanFang Data,China Biology Medicine disc(CBMdisc)and PubMed from database establishment date to November 31,2024.Frequency statistics,association rules and cluster analysis were performed on the data by using R Studio 4.3.0 software,and the analysis results were visualized.[Results]A total of 122 clinical research articles on Tuina treatment for AIS were included,among which 116 were Chinese articles and 6 were English articles.These studies were extracted 122 tuina prescriptions,which involved 75 types of Tuina techniques,with a total application frequency of 376 times.The technique with the highest application frequency was the kneading method.A total of 19 acupoint prescriptions were extracted,involving 48 acupoints with a frequency of 119,among which Shenshu was the most frequently used acupoint.The acupoints mainly belonged to the Bladder Meridian of Foot-Taiyang,the Governing Vessel,the Kidney Meridian of Foot-Shaoyin,the Liver Meridian of Foot-Jueyin and some Extra-meridian Points.Among the combinations of manipulations and acupoints,kneading and Shenshu were used most frequently in combination with other manipulations and acupoints.Association rule network analysis showed that Dachangshu,Shenshu,Weizhong and Chengfu were strongly correlated among acupoints;kneading,pressing and Tuina were strongly correlated among manipulations.In the cluster analysis results,high-frequency acupoints formed 5 effective clusters and high-frequency manipulations formed 3 effective clusters.[Conclusion]Tuina treatment of AIS mainly uses loosening and pulling manipulations as a supplement,focusing on adjusting the balance of Yin and Yang of the spine;the selection of acupoints is mainly in local part combined with those along the meridians.

Objective: To explore the changes of mechanosensitive channels Piezos (Piezo 1 and Piezo 2) in neurogenic bladder (NB) of young rats and their effects，so as to provide reference for clinical search of new therapeutic targets. Methods: A total of 30 female young SD rats were divided into 5 groups based on random number table method：sham operation group (sham)，2-week nerve transection group (NB-2W)，6-week nerve transection group (NB-6W)，2-week nerve transection + Piezos inhibitor group (NB-P-2W) and 6-week nerve transection + Piezos inhibitor group (NB-P-6W)，with 6 rats in each group.The NB models were constructed by transecting the L6 and S1 spinal nerves of young rats.The NB-2W and NB-6W groups were not intervened after modeling，while the NB-P-2W and NB-P-6W groups were intraperitoneally injected with Piezos inhibitor GsMTx4 (10 mg/kg) every 2 days after modeling.Bladder cystometry and ultrasound were performed after 2 and 6 weeks of transection.The expressions of Piezos and fibrosis-related indexes (Collagen Ⅰ and α-smooth muscle actin) were detected in bladder tissues. Results: The results of bladder cystometry showed that the basal bladder pressure in NB-2W group was significantly increased，while it was slightly decreased but was still higher in NB-6W group than in the sham group (P<0.05).Basal bladder pressure was lower in NB-P-2W group than in NB-2W group，but was higher than that in the sham group; basal bladder pressure was lower in NB-P-6W group than in NB-6W group，but higher than that in the sham group (P<0.05).Compared with the sham group，the NB-2W and NB-6W groups had firstly increased and then decreased maximum cystometric capacity (MCC) (P<0.05).Compared with NB-2W group，NB-P-2W group had lower bladder leakage point pressure (BLPP)，but higher MCC and bladder compliance (BC) (P<0.05).Compared with NB-6W group，NB-P-6W group had significantly lower BLPP but higher MCC and BC (P<0.05).HE and MASSON staining and ultrasound results showed that，with the extension of nerve transection time，bladder fibrosis gradually worsened，the bladder wall became rough and thickened，calculi were visible inside，and hydronephrosis gradually appeared; the degree of fibrosis in NB-P-2W and NB-P-6W groups was less than that in NB-2W and NB-6W groups，and no hydronephrosis was observed in the upper urinary tract.In addition，Western blotting and immunohistochemical results showed that NB-2W and NB-6W groups had significantly higher relative expression levels of Piezos，Collagen Ⅰ and α-SMA than the sham group (P<0.01)，while NB-P-2W and NB-P-6W groups had lower relative expression levels of Piezos,Collagen Ⅰ and α-SMA than NB-2W and NB-6W groups (P<0.01). Conclusion: The increased expressions of mechanosensitive channels Piezos in NB young rats may be involved in the progression of bladder fibrosis，but its mechanism needs further study.

Objective The purpose of this study was to provide a more effective method for researching the prevention and treatment of Graves'disease by comparing the effects of two plasmid vectors expressing the human thyrotropin receptor(TSHR)A subunit gene in inducing an animal model of Graves'disease via electroporation.Methods Plasmids pcDNA3.1-THSR A,and pTriEx1.1-THSR A expressing the TSHR A subunit were constructed and used to induce Graves'disease by intramuscular injection with immediate electroporation once every 3 weeks for a total of 4 times.Mice in the control group were injected with PBS.One week after the second electroporation,blood was collected to measure serum thyrotropin receptor antibody(TRAb).Three weeks following the last electroporation,echocardiography was performed on the mice.Mice were sacrificed 4 weeks after the last electroporation;blood,thyroid,and orbital tissues were collected;serum total thyroxine(TT4)was measured;and histological examination was performed.Results The average concentrations of serum TRAb in the pcDNA3.1-TSHR A group(n=15)and the pTriEx1.1-TSHR A group(n=13)were(6.9±2.0)U/L and(7.5±2.2)U/L,respectively.The latter was significantly higher than that in the control group(4.9±0.5)U/L(P=0.033).The average concentrations of serum TT4 in the pcDNA3.1-TSHR A group and pTriEx1.1-TSHR A group were(41.4±23.8)ng/mL and(63.2±53.7)ng/mL,respectively,both higher than that in the control group:(20.2±4.0)ng/mL(P＜0.01).Thyroid pathology showed thyroid follicular epithelial hyperplasia with T-cell infiltration in the model group.Echocardiography showed that the left ventricle mass in the pTriEx1.1-TSHR A group was higher than those in the control group(P=0.007)and pcDNA3.1-TSHR A group(P=0.012).Orbital pathology showed fibrotic changes in the extraocular muscles of mice in the model groups.Conclusions Both pcDNA3.1 and pTriEx1.1 expressing the TSHR A subunit were able to induce Graves'disease in mice by electroporation,and the efficiency of the two plasmids in inducing hyperthyroidism and Graves'ophthalmopathy was similar.The efficiency of pTriEx 1.1-TSHR A in inducing thyrotoxic heart disease was better than that of pcDNA3.1-TSHR A.

[Objective]To analyze the effect of lever positioning manipulation(LPM)on the stress and strain of lumbar spine and intervertebral disc in different regions by using three-dimensional finite element technique,so as to reveal the biomechanical mechanism of manipulation.[Methods]A three-dimensional finite element model of the whole lumbar spine was constructed based on lumbar CT images,and the validity of the model was verified.The finite element model was used to analyze and compare the differences in the stress and strain of lumbar vertebrae and intervertebral discs by LPM at different manipulation points.[Results]The finite element model constructed indicates the point of manipulation is about 15 mm beside the L4 spinous process,the stress around the L4-5 intervertebral disc is large and the intermediate stress is small.The minimum strain point of the L4-5 intervertebral disc is about the lateral area of the intervertebral disc.The stress and strain of other intervertebral discs are similar to those of L4-5 intervertebral discs.The nucleus pulposus of L4-5 intervertebral disc move forward relatively to the lumbar spine;the stress under the lumbar pedicle is large,L4 has a certain degree of activity in the direction of extension,left bending and right rotation.Manipulation point is in the L4 spinous process,the stress around the L4-5 intervertebral disc is large and the intermediate stress is small.The minimum strain point of the L4-5 intervertebral disc is about the central area of the intervertebral disc.The stress and strain of other intervertebral discs are similar to those of L4-5 intervertebral discs.The nucleus pulposus of L4-5 intervertebral disc move forward relatively to the lumbar spine;the stress under the lumbar pedicle is large,and L4 has activity in the extension direction,and the activity in other directions is almost zero.[Conclusion]The LPM has the tendency to restore lumbar curvature and correct lumbar scoliosis and rotation.It can make the lumbar intervertebral disc move closer to the middle and make the nucleus pulposus move forward relatively to the posterior edge of the lumbar spine to reduce disc herniation and release compression.In the treatment of lumbar disc herniation,the manipulation points of the corresponding position can be selected according to the prominent position.
