Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.

OBJECTIVE To provide reference for the subsequent landing of national medical insurance negotiated drugs （referred to as “national negotiated drugs”） at the provincial level. METHODS By reviewing the data publicly released by the official websites of National Healthcare Security Administration and the Healthcare Security Administration of Zhejiang Province， combined with policy documents， the descriptive analysis was conducted on the number of tertiary medical institutions， the actual allocation of national negotiated drugs， the availability rate of national negotiated drugs， the allocation rate of national negotiated drug varieties， and the allocation rate of medical institutions of various cities in Zhejiang province. The Spearman rank correlation test was used to analyze the correlation between the number of types of national negotiated drugs equipped in tertiary medical institutions in Zhejiang province and the per capita disposable income， the number of tertiary medical institutions equipped with national negotiated drugs， and the implementation time of disease diagnosis-related grouping （DRG） of various cities in Zhejiang province. RESULTS As of the first quarter of 2022， 135 tertiary medical institutions in Zhejiang province were equipped with a total of 261 types of national negotiated drugs， accounting for 94.91% of the 2021 edition of the National Negotiated Drugs Catalogue （275 types）. The allocation rates of Goserelin acetate sustained-release implant， Sacubitril valsartan sodium tablets， Alteplase for injection and other varieties were at high level， and the types of national negotiated drugs equipped were highly coincident with the top 10 causes of death with disease of urban and rural residents in Zhejiang province. The tertiary medical institutions in Hangzhou had the most types of national negotiated drugs， with 230 types， while Quzhou had the lowest， with only 34 types； allocation rate of national negotiated drugs in medical institutions of Zhoushan was the highest （100%）， while that of Lishui was the lowest （57.14%）. The types of national negotiated drugs equipped were positively correlated with per capita disposable income in various cities and the number of tertiary medical institutions equipped with national negotiated drugs （P＜0.01）， and there was no significant correlation with the length of implementation of DRG （P＞0.05）. CONCLUSIONS mail：lanyao@mails.tjmu.edu.cn The landing of national negotiated drugs in Zhejiang province is generally good， with a high rate of equipping tertiary medical institutions with national negotiated drugs and a high rate of equipping drug varieties. Therefore， it is recommended that the provincial implementation of national negotiated drugs should be multi-faceted， and policy-making departments should adopt a dual-channel of “unbundling” and “driving” to smooth the drug chain into hospitals. The health insurance sector should improve the “dual channel” management mechanism to share the pressure on hospitals to use drugs. At the same time， it should also improve the multi-level medical security system and raise the level of reimbursement of medical insurance for national negotiated drugs.

Objective: To investigate the clinical effectiveness of anterior cervical discectomy and fusion (ACDF)plus plating in the treatment of unstable Hangman's fractures. Methods: A retrospective case series study was carried out to analyze 12 patients who received ACDF plus plate internal fixation for unstable Hangman's fracture admitted to Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from July 2014 to July 2018. There were nine males and three females, aged 24-70 years with an average of 46.2 years. According to Levine-Edwards typing, there were seven patients of type Ⅱ, four patients of type Ⅱ A and one patient of type Ⅲ. There were two patients of grade D and 10 patients of grade E according to the American Spinal Injury Association (ASIA) classification. The operation time, intraoperative blood loss and the operational complications were recorded. At 3 days, 1, 3, 6, 12 and 24 months after operation, the height of intervertebral disc, physiological curvature of cervical spine, fracture healing and bone graft fusion were evaluated. The recovery of neurological function was assessed by ASIA, and the neck pain relief and function improvement was assessed by visual analogue scale (VAS) and the neck disability index (NDI). Results: All patients were followed for 6-48 months(mean, 27.7 months). The operation time ranged from 50-100 minutes, with an average of 72.5 minutes. The intraoperative blood loss was 30-120 ml (mean, 65.8 ml). No serious complications occurred during and after operation. Two patients had dysphagia after operation, and the symptoms were relieved at the follow-up of 3 months. All patients achieved bony fusion of C_2-3 within the 6 month follow-up. No subsidence or migration of cages and significant loss of intervertebral space height were observed. The patient's neck and occipital pain was relieved obviously, and the flexion, extension and rotation of cervical spine were good. The neurologic dysfunction of two patients of ASIA Grade D recovered after surgery, and the final ASIA grade was E. The VAS score was decreased from 5.0 (4.0, 6.0)points preoperatively to 1.0(0, 1.0)points at the last follow-up (P<0.01). The NDI score was improved from (28.5±6.4)points preoperatively to (5.3±2.7)points at the last follow-up (P<0.01). Conclusion ACDF combined with plate internal fixation can provide immediate postoperative stability, high fusion rate, less complications, less pain, and satisfactory function recovery.

Objective To discuss the correlation between gastrointestinal symptoms concomitant with chronic migraine and sleep disorders,anxiety and depression.Methods Self-rating Anxiety Scale (SAS),Self-rating Depression Scale (SDS),Pittsburgh Sleep Quality Index (PSQI) and Gastrointestinal Symptom Rating Scale (GSRS) were adopted to conduct comparative analysis on gastrointestinal symptoms,anxiety,depression,sleep disorders,and related risk factors in 151 chronic migraine patients who conformed to International Headache Society International Classification of Headache Diseases-Ⅱ diagnostic code and 151 healthy controls in the Third Affiliated Hospital of Qiqihar Medical University from January 2015 to December 2017.Results PSQI scores (8.46±2.54 vs 4.53±1.95,t=2.913,P＜0.05),SAS scores (53.24± 11.66 vs 39.58±8.63,t=3.112,P＜0.05),SDS scores (51.09±8.80 vs 36.11±5.74,t=3.520,P＜0.05),and GSRS scores (4.53 (3.74,5.32) vs 1.29 (0.73,1.31),Z=30.804,P＜0.05) were all higher in migraine patients than that in healthy controls,and the differences were all statistically significant.In chronic migraine patients,139 (92.05％) had one gastrointestinal symptom at least,and the overall incidence of each gastrointestinal symptom was abdominal distension (60 cases,39.74％),exhaust increase (51 cases,33.77％),and endless defecation (43 cases,28.48％),etc.,in turn.Multiple regression analysis showed that headache degree,frequency,PSQI scores,SAS scores,and SDS scores were the main risk factors of gastrointestinal symptoms concomitant with chronic migraine.GSRS scores of chronic migraine patients presented positive correlation with PSQI scores (r=0.65,P=0.000),SAS scores (r=0.42,P=0.000),and SDS scores (r=0.48,P=0.000),respectively.Conclusion Chronic migraine patients are easy to be accompanied with gastrointestinal symptoms,and headache degree and frequency,sleep disorders,depression and anxiety are the main risk factors of concomitant gastrointestinal symptoms.

Objective: To analyze the morbidity, clinical characteristics, therapeutic outcomes and prognosis of cardiac lymphoma. Methods: Individual patient data were obtained from pathology defined 10 cases of cardiac lymphoma from Jan 2000 to Jun 2016. The patient’s general information, clinical manifestation, pathological diagnosis, laboratory examination, cardiac involvement feature, cardiac complications, treatment, therapeutic effect and prognosis were analyzed. Results: Of 3 918 cases of lymphoma patients, 10 cases of cardiac involvement were identified, including primary cardiac lymphoma (PCL) in 1 case, secondary cardiac lymphoma (SCL) in 9 cases. Of the 10 patients in our analysis, the male-to-female ratio was 3∶2, with a median age of 55 (19-88) years old. The most presenting complaints were dyspnea in 7 cases, followed by chest pain in 5 cases, fatigue in 2 patients and edema in 2 cases. Pathological types included diffuse large B cell lymphoma (DLBCL) in 7 cases, T cell lymphoma (T-LBL) in 1 case, Hodgkin’s lymphoma (HL) in 1 case, and Burkitt lymphoma (BL) in 1 case. The sites of the heart affected by lymphoma in the PCL patient were right and left atriums with multiple nodules; and for SCL, the sites were mainly pericardium associated with a pericardial effusion in 5 cases, a pericardial mass in 2 cases. Congestive heart failure affects 7 patients and cardiac arrhythmias were identified in 4 cases mainly sinus tachycardia, atrial fibrillation and atrioventricular block. Except one untreated because of old age and poor performance, the rest of 9 patients were treated by either chemotherapy in 4 cases or chemotherapy combined radiotherapy (including the extracardiac sites) in 5 patients. With the median follow-up of 9 months, the one PCL patient achieved partial response (PR) , progress free survival (PFS) for 6 months and the overall survival (OS) for 21 months; in the cohort of 6 SCL patients cardiac involved at diagnosis, complete response (CR) was achieved in 1 case (16.7%) , PR in 3 cases, progressing disease (PD) in 2 cases, with the median PFS for 5 months and the median OS for 19 months; and for the other 3 SCL patients cardiac involved at progression, PR was achieved in 2 case and death in 1 case, with the median PFS for 4 months and the median OS unavailable because of censored data. Conclusion Cardiac lymphoma represents a rare subset of lymphoma, the most common type is DLBCL, and the main clinical manifestations are dyspnea and chest pain, always combined by arrhythmia and congestive heart failure. The main therapeutic regimen for cardiac lymphoma includes combined chemotherapy and the prognosis for patients with either PCL or SCL is usually poor.

Objective: To investigate the risk factors of poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for severe aplastic anemia (SAA) . Methods: Clinical data from 111 SAA patients who received allo-HSCT were analyzed retrospectively. Factors including age, gender, interval to transplantation, the level of serum ferritin before transplantation were analyzed by Cox multivariate regression analysis. Results: Among the 111 patients who underwent allo-HSCT, 16 developed PGF (14.4%) . Multivariate analysis showed donor type (HR=2.656, 95%CI 1.204-5.858, P= 0.016) and the level of serum ferritin before tansplantation (HR=3.170, 95%CI 1.400-7.180, P=0.006) were significant risk factors for PGF. Conclusion Unrelated donor transplantation and the high level of serum ferritin before transplantation are risk factors for PGF.

Objective To discuss the impact of target exposure via retrosigmoidal approach in surgical injury based on virtual reality anatomic models.Methods CT and MR imaging data of 15 adult cadaver heads were utilized to establish three-dimensional anatomy models of petrous bone.Surgical routes exposing different targets though retrosigmoidal approach were simulated by selecting osseous landmark points on the calvaria and skull base.Special form and sequence of anatomic structures in different routes were observed.Volumes of anatomic tissues were measured.Results All the surgical routes passed below the transverse sinus and lateral to the cerebellum.Route a exposed the lower cranial nerve and anterior inferior cerebellar artery;when reached the jugular tubercle,the route exposed inferior petrous sinus.Route b exposed the anterior inferior cerebellar artery,labyrinth and facial-acoustic nerve complex.Route c passed the medial to the superior petrous sinus and exposed the facial-acoustic nerve complex;when being arrived at petrous apex,the route exposed the trigeminal nerve,superior cerebellar artery and cavernous sinus.The volumes of the lower cranial nerve,osseous structures,cerebellum and artery were significantly different in models adopted different routes (P＜0.05);the volume of the lower cranial nerve was as follows:route c＞route a＞route b,the volume of osseous structures was as follows:route c ＞route b＞route a,the volume of cerebellum was as follows:route b ＞route a＞route c,and the volume of artery was as follows:route a ＞route c＞route b.Venous structure involved in route a ([68.91 ±1.91] mm3) was larger than that in route c ([248.92±11.26] mm3) with statistical significance (P＜0.05),and route b did not involve venous structure.Conclusions Targets in skull base has significant impaction on the size of anatomic structures involved in the route of retrosigmoidal approach.Relationship between injury and exposure can be evaluated objectively by the volume measurement.

Objective To investigate the effect of sodium nitroprusside sustained release on cognitive function, S-100βprotein and VILIP-1 in pituitary tumor surgery patients.Methods 156 cases of pituitary tumor patients were selected and divided into two groups according to random number table method,78 patients in each group.All patients underwent general anesthesia induction,the experimental group treated with 0.5~6 μg ( kg· min) infusion of sodium nitroprusside induced hypotension by micro pump at the beginning of operation.MMSE was used to determine the cognitive function of 2 groups of patients 1 day before operation and 2 days after operation,S-100βand VILIP-1 content were determined by ELISA before anesthesia,after surgery,and 0,12,24,48 h after operation.Results There was no statistical significance between the 2 groups in the incidence of postoperative cognitive dysfunction.Compared with control group, the operation time, bleeding volume and the recovery time of the experiment group were lower(P<0.05).S-100βprotein and VILIP-1 showed increased at first and then decreased at the peak of 24h;compared with the normal group, the levels of S-100βprotein and VILIP-1 of the cognitive impairment were higher ( P <0.05 ).Compared with the control group, the levels of S-100βprotein and VILIP-1 of the experiment group were lower(P <0.05).Conclusion Sodium nitroprusside sustained release controlled hypotension can reduce the level of cognitive disorder, patients of S-100βprotein and visinin-like protein 1 and has certain directive significance to the clinical.

OBJECTIVETo conduct a clinical trial of ketogenic diet (KD) in patients with acute spinal cord injury (SCI) and evaluate its safety and feasibility by measuring blood ketone bodies and blood glucose levels.

METHODTen patients with acute SCI were recruited in the trial during the period from May, 2012 to October, 2013. The patients received a standard KD after fasting for 48 h. The levels of blood ketone, blood glucose and uric ketone were tested daily, and routine blood examination, electrolytes, liver and kidney function, body mass index (BMI), sensory and motor function, and adverse reactions were monitored weekly to assess the safety and feasibility of KD.

RESULTSKD treatment lasted for a mean of 12.9 days (4 to 29 days) in these patients. In all the patients, blood ketone level increased during the fasting and maintained a level above 2.0 mmol/L after taking KD, while the uric ketone level ranged from +++ to ++++. The blood glucose level was in the normal range during KD. Except for blood chloride level and BMI, routine blood test results, electrolytes, liver and kidney function showed no significant changes after KD. No significant changes were observed in the sensation of light touch and pinprick. The average motor ASIA score increased from 33.3 to 35.1 after KD. Gastrointestinal dysfunction (diarrhea, nausea, poor appetite, gastric pain, and abdominal distension) was recorded in 5 patients, hypoglycemia occurred in one patient early after KD, and one patient experienced urticaria during KD. All the adverse reactions were relieved after symptomatic treatments.

CONCLUSIONThis preliminary clinical trial demonstrated that KD could increase ketone bodies level and maintain a normal blood glucose level, suggesting its safety and feasibility in patients with acute SCI.
