OBJECTIVE: To observe the effects of point-moxibustion with Zhuang medicinal thread on differentially expressed genes (DEGs) in the dorsal root ganglion (DRG), tissue morphology, and the expression of Fc epsilon RI (FcεRI) pathway proteins spleen tyrosine kinase (Syk) and membrane spanning 4-domain A2 (MS4A2) in rat model of postherpetic neuralgia (PHN), and to explore the potential mechanism by which this therapy alleviates pain sensitization. METHODS: Thirty-nine male Sprague-Dawley (SD) rats were randomly divided into a control group, a model group, and a moxibustion group, with 13 rats in each group. The PHN model was established in the model and moxibustion groups by intraperitoneal injection of resiniferatoxin. In the moxibustion group, bilateral L₄-L₆ "Jiaji" (EX-B2) points were treated with point-moxibustion with Zhuang medicinal thread from day 7 post-modeling, with two cones per acupoint per session, every other day for a total of 10 sessions. Mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured at 1 day before modeling and on days 1, 4, 7, 13, 19, and 25 after modeling. After intervention, HE staining was used to observe DRG morphology. RNA sequencing was performed to analyze DEGs in DRG and conduct bioinformatics analysis. The expression of Syk and MS4A2 mRNA and proteins in the FcεRI pathway in DRG was detected by quantitative PCR and Western blot. RESULTS: Compared with the control group, the model group exhibited decreased MWT (P<0.05) and increased TWL (P<0.05); histopathological analysis revealed neuronal atrophy, nuclear displacement, and intracellular vacuoles, with a slightly loose arrangement; the RNA-Seq identified 3,207 DEGs (1,997 upregulated and 1,210 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly increased (P<0.01). Compared with the model group, the moxibustion group showed increased MWT (P<0.05) and decreased TWL (P<0.05), with relatively normal neuronal morphology; the RNA-Seq identified 426 DEGs (250 upregulated and 176 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly decreased (P<0.05). Venn diagram analysis identified 156 DEGs that showed a reversal in expression trends after treatment, including Syk and MS4A2, which are associated with pain sensitization. KEGG pathway analysis indicated that these DEGs were primarily enriched in the FcεRI pathway. CONCLUSION Point-moxibustion with Zhuang medicinal thread could alleviate pain sensitization in PHN rats, possibly by inhibiting the FcεRI signaling pathway and downregulating the expression of Syk and MS4A2.

Objective:To discuss the clinical manifestations and laboratory examination results of agranulocytosis and reactive plasmacytosis(RP)in the patient with Graves'disease(GD)after treated with methimazole(MMI),and to provide the basis for the clinicians to differentiate RP from multiple myeloma(MM).Methods:The clinical manifestations,laboratory examinations,diagnosis and treatment processes of one patient with GD agranulocytosis complicated with RP were analyzed,and the related literatures were reviewed.Results:The patient had a history of GD and abdominal infection.Upon admission,a complete blood count revealed a significant decrease in white blood cell count accompanied by neutropenia,and a smear re-examination showed suspicious plasma cells.The bone marrow cytology examination results showed the percentage of bone marrow plasma cells was 33％,and the percentage of plasma cells in peripheral blood was 4％;the serum immunoglobulin results showed polyclonal hyperplasia;the serum immunofixation electrophoresis results were negative;the flow cytometry analysis results indicated the immunophenotype of the plasma cells was normal.Based on the medical history and laboratory results,MM was largely excluded,supporting the diagnosis of RP.Neutropenia was considered to be related to medication,so MMI was discontinued,granulocyte colony-stimulating factor was administered to increase the number of white blood cells,and specialized GD treatment was conducted after controlling the abdominal infection.The patient had a good prognosis,and his blood count was normal upon re-examination 6 months later.Conclusion:Agranulocytosis complicated with RP in the GD patients is clinically rare.Serum immunofixation electrophoresis,blood cell morphology,and cell immunophenotype analysis are helpful for the accurate diagnosis.After actively treating the primary disease causing RP,the patient's prognosis is favorable.

Objective To investigate the clinical efficacy of arthroscopic simple repair technique and en-hanced repair technique in the treatment of chronic lateral ankle instability(CLAI).Methods Forty-one cases of CLAI treated in the General Hospital of Northern Theater Command of PLA from January 2018 to January 2019 were selected and conducted arthroscopic lateral ankle ligament repair or enhanced repair treatment.The follow up data in 39 cases were complete.Among them,18 cases conducted the anterior talofibular ligament repair with wire anchor under arthroscopy and were included in the repair group,while 21 cases conducted the arthroscopic enhanced repair with linear anchors and knots free anchors and were included in the enhanced re-pair group.The postoperative follow up lasted for 12 months.The VAS score and AOFAS ankle-hind foot score before operation and in postoperative,3,6,12 months were compared between the two groups.The effi-cacies of treating CLAI by the two operation modes were evaluated.Results The preoperative VAS score and AOFAS ankle-hind foot score had no statistical differences between the two groups(P＞0.05).The VAS score at postoperative time points had no statistical difference between the enhanced repair group and repair group(P＞0.05).The AOFAS ankle-hind foot score in the enhanced repair group was higher than that in the repair group,and the difference was statistically significant(P＜0.05).No serious complications occurred in the grouped patients during the follow up period.Conclusion In terms of pain and ankle function,the effect of arthroscopic enhanced repair in treating CLAI is better than that of simple repair.

Objective:Under the background of "new medical science", to construct a whole-process education path with "education as the driving force - moral cultivation as the core", and to provide a decision-making basis for the reform, innovation, and development of humanistic quality education in medical colleges.Methods:Five-year clinical medical students (freshman to fifth graders) from Qiqihar Medical University were selected as the research objects. The evaluation model and questionnaire of humanistic quality of clinical medical students were constructed by literature analysis. The Questionnaire Star platform was used to investigate and collect data by random sampling of clinical medical undergraduates, and the data results were analyzed by SPSS 26.0 to explore the path of building the whole-process education.Results:The empirical research on the cultivation of humanistic quality of medical students showed that the average humanistic attitude score of medical students was (3.47±0.75) points. From the perspective of gender, the scores of humanistic cognition, attitude, and behavior of male students were 2.81, 3.68, and 3.22 points, respectively, which were all significantly higher than those of female students (2.52, 3.22, and 2.95 points, respectively) ( P<0.05). The data from freshmen to the fifth graders showed that humanistic cognition, attitude, and behavior scores all presented an increasing trend with the grade. Using the "Knowledge, Attitude/Belief, Practice" model, it was found that the cognitive rate of humanistic quality of medical students was relatively ideal, and the awareness rate of medical students in different grades was different. The cross analysis showed that the effect of ideological morality and political literacy education on medical students in medical colleges had a significant cross-relationship with multiple choice questions. Conclusion:The humanistic quality of clinical medical students needs to be improved, and the cultivation of medical humanistic quality should run through the whole process from the first year to the fifth year, so as to improve the comprehensive training of professional ability and promote the all-round development of medical students.
