Objective To construct an animal model with a high consistency of trigeminal neuralgia,this paper systematically reviewed and summarized the existing animal models based on the etiology and pathogenesis analysis of Chinese and western medicine,clinical diagnostic criteria and evaluation indexes of animal models.Methods Literatures on animal models of trigeminal neuralgia were consulted through CNKI and PubMed databases,the etiology and pathogenesis of Chinese and western medicine in the treatment of TN,diagnostic criteria of Chinese and western medicine,model replication objects in common animal models of trigeminal neuralgia,model replication methods and consistency of clinical manifestations of Chinese and western medicine were summarized and analyzed.Results At present,the most widely used model is the"infraorbital nerve injury"surgical model,which has high similarity in pathological manifestations with the clinical features of trigeminal neuralgia.Secondly,the chemical induction model of"penicillin injection"showed significant effect of inducing acute pain-like reactions.The photochemical induction model can effectively avoid the influence of factors such as tightness during surgical modeling process on the experimental results.Conclusion The current modeling method of integrated traditional Chinese and western medicine is still in the stage of exploration and has not formed a mature theoretical system.Therefore,we should actively invest more resources to develop animal models more closely related to traditiona Chinese medicine(TCM)syndromes in future research.The purpose is to provide strong theoretical basis and experimental support for the treatment of trigeminal neuralgia with integrated Chinese and western medicine.

Objective To explore the effect of occupational skills relearning programme on hemiplegic arm motor function and ac-tivities of daily living(ADL)in stroke patients. Methods From February,2022 to August,2023,74 stroke patients in Guangdong Work Injury Rehabilitation Hospital were enrolled and randomly divided into control group(n=37)and experimental group(n=37).The control group received conventional rehabilitation training,and the experimental group received additional occupational skills relearning programme,for three weeks.They were assessed with Fugl-Meyer Assessment-Upper Extremi-ties(FMA-UE),Functional Test for the Hemiplegic Upper Extremity-Hong Kong(FTHUE-HK),Motor Activity Log(MAL)-amount of use(AOU)and MAL-quality of movement(QOM),modified Barthel Index(MBI),and Stroke Impact Scale(SIS)-Hand and SIS-ADL before and after treatment. Results The scores in all assessments improved significantly in both groups(|t|>3.597,P<0.05)after treatment,while the scores of FMA-UE,FTHUE-HK,MAL-AOU,MAL-QOM were higher in the experimental group than in the control group(|t|>2.352,P<0.05). Conclusion Occupational skills relearning programme could promote the recovery of hemiplegic arm motor and activity,and facilitate the use of the hemiplegic arm in daily life in stroke patients.

Objective To explore the effect midazolam combination with propofol on postoperative recovery in patients undergoing laparoscopic cholecystectomy. Methods A total of 162 patients who were admitted to the hospital for laparoscopic cholecystectomy from April 2019 to January 2021 were selected. According to different anesthesia methods, they were divided into control group (midazolam anesthesia) and observation group (midazolam combined with propofol anesthesia), with 81 cases in each group. The stress index levels before and after operation, MoCA scores before operation (T₀), 24 h after operation (T₁) and 48 h after operation (T₂), sleep quality at T₀, the first day after operation (T₃) and the second day after operation (T₄), the perioperative recovery were compared between the two groups. Results The levels of Cor and NE, the recovery time of eyes opening, extubation, orientation, and the incidence of adverse reactions in the observation group were lower than those in the control group (P<0.05). Observation group MMSE score when T₁, T₂, T₃, T₄ sleep quality score were higher than control group (P<0.05). Conclusion Midazolam combined with propofol was safe and had good postoperative recovery in patients undergoing laparoscopic cholecystectomy.

OBJECTIVE: To discuss the diagnosis and effective treatment of cystic lymphangiomas located in head and neck in children. METHOD: Fifteen cystic lymphangiomas,diagnosed with pathological evidence, located in head and neck in children were retrospectively analyzed including clinical characteristics, diagnosis, treatment and follow-up data. RESULT: CT and ultrasonography were used to evaluate the size, shape and extent of lymphangiomas in all patients. All patients were treated with surgery. Complete resection was performed in 14 cases, and subtotal resection in one case. Two post-operative complications were found,one was paralyses of mandibular branch of facial nerve, another was Horners syndrome. Tracheotomy operation was done in one case,and the tracheal cannula was taken away before discharged from hospital. Fourteen patients were followed up. There was no recurrence during the follow-up from 6 months to 8 years, while one case who suffered from Horner's syndrome after operation was not cured. CONCLUSION CT and ultrasonography are effective to diagnose cystic lymphangiomas and evaluate the security of clinical treatment. Total or subtotal resection is effective to treat cystic lymphangiomas.

OBJECTIVE: To analyze the clinical characteristics and treatment of bilateral and unilateral sudden sensorineural hearing loss (SSHL) and figure out the differences between bi-and unilateral sudden sensorineural hearing loss, and further improve the diagnosis and treatment of SSHL. METHOD: The retrospective study was based on 334 patients with SSHL (315 with uni-SSHL versus 18 with bi-SSHL) and all of the patients were in-patients. RESULT: The incidence of bi-SSHL was 5.4% of patients with SSHL. There was no significant difference on the clinical features such as age, gender, interval from onset of symptoms to seeing doctors and associated symptoms between bi-and unilateral SSHL. 27.8% of the patients with bi-SSHL had preexisting diabetes mellitus, which was significantly higher than the rate of the uni-SSHL (9.8%, P<0.05). Hearing loss was more profound in the uni-SSHL ones, however, the hearing improvements were better than their counterparts. The overall effective rate of the two groups was 58.4% and 13.9% respectively. Earlier diagnosis and treatment with steroids would have a good prognosis. CONCLUSION Unilateral SSHL is more common than bilateral SSHL. Bilateral SSHL occurs more common with preexisting diabetes mellitus and has worse prognosis compared to unilateral SSHL. The earlier steroid treatment the better prognosis.
