Objective To analyze the research hotspots,frontiers,and trends in clinical randomized controlled trials(RCTs)on acupuncture-moxibustion for post-stroke shoulder-hand syndrome(SHS)over the past decade using bibliometric and knowledge mapping methods.Methods The clinical RCTs on acupuncture-moxibustion for post-stroke SHS from five Chinese and English databases were retrieved,including CNKI,Wanfang,VIP,PubMed,and Web of Science(WOS).CiteSpace and VOSviewer were employed for analysis,and visualized knowledge maps were generated.Results A total of 1 226 Chinese and 20 English articles were included,with both reaching publication peaks in 2021.The top three institutions in terms of output were Huguosi Traditional Chinese Medicine Hospital Affiliated to Beijing University of Chinese Medicine,The Second Affiliated Hospital of Heilongjiang University of Chinese Medicine,and Heilongjiang University of Chinese Medicine.The most prolific author was Song Fengjun,while Pei Jian had the highest centrality.The five most frequently used keywords were shoulder-hand syndrome,stroke,acupuncture-moxibustion,rehabilitation training,and joint mobility.Emerging research topics included activities of daily living,limb function,and range of motion.Conclusion Clinical research on acupuncture-moxibustion for post-stroke SHS holds significant developmental potential.Strengthening international collaboration to explore therapeutic mechanisms is recommended,and researchers should continue optimizing treatment protocols to enhance the quality of clinical evidence.

Objective:To induce an experimental autoimmune encephalomyelitis(EAE)model by MOG-specific TCR trans-genic mice(2D2TCR transgenic mice),and to investigate effect of exogenous ERMAP on T cells in spleen of MOG35-55-induced 2D2TCR transgenic mice.Methods:EAE models were established in two groups of 2D2TCR transgenic mice(Control-Ig treatment for control group and ERMAP-Ig fusion protein treatment for experimental group),with 9 mice per group.Severity of spinal cord injury of MOG35-55-induced EAE in mice was assessed based on daily clinical scores(DAI),HE and LFB staining results;autoreactive T cells(CD4+Vα3.2+Vβ11+),T cell proliferation activation indicators CD69(CD4+Vα3.2+Vβ11+CD69+)and Ki67(CD4+Vα3.2+Vβ11+Ki67+),Treg(CD4+Vα3.2+Vβ11+CD25+Foxp3+)and Th17 cells(CD4+Vα3.2+Vβ11+IL-17A+)in spleen were detected by flow cytome-try;IL-17A,IL-6,IFN-γ and TGF-β expressions in spinal cord tissues were detected by qRT-PCR.Results:In MOG35-55-induced 2D2TCR transgenic mouse EAE model,ERMAP-Ig fusion protein treatment group showed milder inflammatory infiltration and demye-lination in spinal cord,decreased proportion of autoreactive T cells,decreased proportion of activated and proliferating T cells,increased proportion of Treg,inhibition of Th17 cell differentiation,less inflammatory cell aggregation and cytokine production,and increased expression of anti-inflammatory factors in spinal cord.Conclusion:ERMAP may be involved in development of EAE in 2D2TCR transgenic mice by inhibiting T cell proliferative activation and promoting Treg cell production.

Objective To study the effects of different color light stimulus, duration of stimulus and day/night training on the incentive conditioned reflex of rats,and to provide a data basis for the methodology of incentive conditional reflection experiments. Methods Three experiments were included in this study. During the experiment 1, a total of 30 male 8-week-old Wistar rats were divided into three groups:red light stimulation group,yellow light stimulation group and blue light stimulation group. During the experiment 2, a total of 32 male 8-week-old Wistar rats were divided into three groups:the group I(with a light stimulation duration of 10 s), the group II(with a light stimulation duration of 30 s), and the group III(with a light stimulation duration of 60 s). During the experiment 3,a total of 16 male 8-week-old Wistar rats were randomly divided into two groups,of which the first group was trained at 9:00 a.m. every day, and the second group was trained at 21:00 every day. All the laboratory animals were given reward conditioned reflex training, and indicators such as the number of correct nose pokes,the number of incorrect nose pokes,the ratio of correct nose pokes and so on were counted and calculated. Results During the experiment 1,there was no significant difference in the numbers of correct nose pokes and incorrect nose pokes,movement distances and average speeds of the rats among the three groups. During the experiment 2,compared with the group with a light duration of 10 s,the rats in the groups with a light duration of 30 s or 60 s had a higher number of correct nose pokes(P< 0.05). Moreover,on the 13th and 14th days,the ratio of correct nose pokes of the group with a light duration of 30 s was significantly higher than that of the group with a light duration of 10 s(P< 0.001). During the experiment 3,there were no significant differences in the number of correct nose pokes and the nose poke accuracy of the rats between the two groups. Conclusions In the reward conditioned reflex test, red,yellow and blue light stimuli have similar reward prediction effect. When stimulated with the same light, the time of stimulation has an impact on the learning ability of the rats,and an appropriate extension of stimulation is beneficial to the formation of conditioned reflex in them. The day/night training has no effect on the learning and memory ability of the rats.

RNA editing, especially A-to-I RNA editing, is a common post-transcriptional modification in mammals. Adenosine deaminase acting on RNA (ADAR) is a key protein for A-to-I editing, which converts the adenosine group of a double-stranded RNA to creatinine group by deaminating it, resulting in a change of nucleotide sequence. There are 3 types of ADARs (ADAR1, ADAR2, ADAR3) that have been found in recent years. The abnormalities of ADARs are closely related to many human diseases such as viral infections, metabolic diseases, nervous system diseases, and tumors.

This study is to investigate the antitumor activity of CIP-36 on multidrug resistant human oral squamous carcinoma cell line (KBV200 cells) in vitro and the possible anticancer mechanisms. MTT assay, Hoechst fluorescein stain, RT-PCR and immunohistochemistry were carried out on KBV200 and KB cells. The growth of many tumor cells was obviously inhibited by CIP-36, especially the multidrug resistant cells KBV200. Obvious apoptosis could be observed in the Hoechst 33342 staining experiments. The results of RT-PCR showed that the levels of p53, p21, caspase-3 and bax mRNA increased, and meanwhile the expression of mdr-1 and bcl-2 mRNA decreased in a dose-dependent manner. The data were significantly different from that of vehicle. The expression of P-gp significantly decreased with the increasing dosage of CIP-36 examined by immunohistochemistry. It can be concluded that CIP-36 could change resistance-related genes and proteins to overcome multidrug resistance in the KBV200 cell line.
