Objective To explore the differences in scapular motion and shoulder function between patients suffering from rotator cuff tears(RCT)with and without type Ⅲ scapular dyskinesis(SD).Meth-ods Between September 2021 and March 2023,sixteen patients suffering from rotator cuff tears with SD(SD group)and 17 counterparts without SD(non-SD group)were recruited from the Sports Hospital of the General Administration of Sport of China.Their scapular motion was assessed by measuring three parameters in the X-rays,including scapular spine line(LSS),scapular upward rotation angle(SU-RA),and coracoid upward shift distance(CUSD).Moreover,their shoulder range of motion in flexion,abduction and external rotation were recorded,and further evaluated using the Pain Visual Analog Scale(VAS)and American Shoulder and Elbow Surgeons Score(ASES).Results No significant differenc-es were found between the two groups in the average score of SURA,CUSD and LSS at 0°～30° shoul-der abduction,or in that of CUSD and LSS at 60°～90°shoulder abduction.However,the average SU-RA score of the SD group at 60°～90°shoulder abduction was significantly greater than the other group(P<0.05).The shoulder ranges of motion during active flexion,abduction and external rotation were significantly smaller in the SD group than in the non-SD group(P<0.05).Moreover,the average VAS score in the SD group was significantly higher than the non-SD group(P<0.05),while the average ASES score was significantly lower than the latter group(P<0.05).Conclusions RCT patients type III SD exhibits greater scapular upward rotation during shoulder abduction compared to those without SD.Moreover,the former patients suffer from more severe pain and have worse shoulder range of motion and functional performance than the latter.

Objective:To summarize the clinical characteristics and efficacy of hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy.Methods:Eleven patients with hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy admitted to Neurosurgical Center, 988 th Hospital of PLA Joint Logistic Support Force from June 2011 to September 2019 were chosen in our study; primary diseases included meningioma in 7 patients, contusion and laceration of frontal lobe in 2, hypertensive cerebral hemorrhage in 1, and obsessive-compulsive disorder in 1 patient. Epilepsy was the first symptom after craniotomy. Clinical characteristics and efficacy of these patients were analyzed retrospectively; seizure control efficacy was evaluated by Engel grading. Results:First seizure occurred 4 h-7 d after craniotomy in these 11 patients, including 2 with focal sensory retention seizure, 3 with focal bilateral tonic-clonic seizure, and 6 with general tonic-clonic seizure. Follow-up cranial CT revealed hematoma in surgical region, adjacent cortex or subcortex in 9 patients (hematoma volume: 15-50 mL); emergency craniotomy (hematoma clearance) and decompressive craniectomy was performed in 5 patients; only emergency craniotomy (hematoma clearance) was performed in 3 patients; conservative treatment was performed in 1 patient. A small amount of diffuse bleeding with severe cerebral edema in the surgical region appeared in 2 patients, and the transient limb paralysis gradually recovered after 2 months of conservative treatment. Follow-up was performed for (4.5±1.7) years ([2.3-7.0] years). During the last follow-up, 4 patients were normal, 5 patients had mild to moderate hemiplegia, 1 had mild decreased vision in the right eye, and 1 had long-term coma. Epileptic control efficacy analysis indicated that 8 had Engel grading I and 3 grading II.Conclusion:Complete removal of hematoma and inactivated brain tissues can effectively control seizures and rebleeding in patients with hemorrhage resulted from cortical venous infarction.

Objective:To investigate the imaging and electrophysiological characteristics, surgical methods and efficacies of preschoolers with refractory temporal lobe epilepsy.Methods:A retrospective data study was conducted on 27 patients with refractory temporal lobe epilepsy accepted surgical treatment in our hospital from June 2014 to January 2019. By combined with clinical manifestations, preoperative epileptogenic zones were evaluated by imaging data, such as MR imaging, MR spectroscopy and positron emission tomography-CT, and interictal and ictal video-electroencephalogram (VEEG) data. During the surgery, cortical electroencephalography (ECoG) and deep electrode monitoring were used to monitor and locate the abnormal discharge areas to guide the surgical excision of epileptic zone. Engel grading was used to evaluate the efficacy after surgery.Results:All children had typical clinical manifestations of temporal lobe epilepsy; abnormal signal images were found in one side of the temporal lobe and the hippocampus in MR imaging; epileptic discharges were originated from one side frontotemporal region in interictal and ictal VEEG. Obviously persistent or paroxysmal spike waves, spike waves and slow spikes and spike composite waves were intraoperatively discovered by ECoG and depth electrode electroencephalography in the temporal lobe. All patients accepted standard anterior temporal lobectomy+lesion resection+peripheral abnormal discharge resection of the temporal lobe cortex; partial insular lobe was excised and frontal cortex was performed low power thermal coagulation in two patients. Follow-up was performed for 6 months; Engel grading I was reported in 22 patients (81.5%), Engel grading II in 3 patients (11.1%), and Engel grading III in 2 patients (7.4%).Conclusion:Early surgery and moderate extension of resection under intraoperative ECoG and deep electrode monitoring are the key factors to improve the surgical efficacy of preschoolers with refractory temporal lobe epilepsy.

Objective To investigate the restrictive factors in the development of foreign medical education. Methods From the years 2011 to 2013, 350 foreign students conducted a questionnaire survey in Chongqing Medical University, and recovered 339 valid questionnaires. Results Only 33.0%(112/339) students thought that the teacher's English was fluent and 70.2% (238/339) needed to add Chinese class. Additionally, 69.6% (236/339) and 63.1% (214/339) students considered theoretical knowledge and practi-cal experience were not enough. 92.3%(313/339) students came from developing countries in Southeast Asia. 86.1%(292/339) foreign students considered that university management was insufficient. Conclusion The survey found the restrictive factors included students' demand for English and Chinese, lack of medical ex-pertise and practice, the problem of student sources and daily management difficulties and so on.

Objective To investigate the influence of Ulinastatin (UTI) on the hyper-permeability of vascular endothelial cells induced by tumor necrosis factor alpha (TNF-α).Methods Inflammation model was induced by TNF-α in human umbilical vein endothelial cell line (EA.hy926).The experiment was designed into 4 groups:normal group,TNF-α group,UTI group and TNF-α with UTI (U + T) group.Methyl thiazolyl tetrazolium (MTT) method and epithelial voltameter (EVOM) method were used to measure cell viability [absorbance (A) value] and transepithelial electrical resistance (TER) of EA.hy926 cells respectively.The expression of VE-cadherin was measured by reverse transcription polymerase chain reaction (RT-PCR) and immunocytochemistry.Results Compared with normal group,the TER of EA.hy926 cells induced by TNF-α was significantly decreased (67.200 ± 8.937 vs.33.600 ± 8.771,P =0.010).The permeability in EA.hy926 cells increased obviously.The hyper-permeability of EA.hy926 cells induced by TNF-α could be alleviated by UTI at the concentrations of 1-100 U/mL in a dose-dependent manner (40.133 ±7.484 vs.33.600 ±8.771,P=0.382;49.232 ± 3.162 vs.33.600 ± 8.771,P =0.044;63.700 ± 8.515 vs.33.600 ± 8.771,P =0.013).The expression of VE-cadherin mRNA reduced significantly in the TNF-α group (1.089 ±0.018 vs.0.835±0.021,P =0.000) compared with normal group.This effect of TNF-α could be attenuated by UTI.When EA.hy926 cells exposed to UTI at 10 U/mL and 100 U/mL,a significant increase of the expression of VE-cadherin mRNA was observed (0.976 ±0.014 vs.0.835 ±0.021,P =0.001;1.115 ±0.015 vs.0.835 ± 0.021,P =0.000).And the inhibition of UTI manifested a dose-dependent manner (1-100 U/mL).The results of the immunocytochemistry showed that the expression of VE-cadherin in TNF-o group was decreased significantly (0.061 ± 0.013 vs.0.093 ± 0.014,P =0.049) compared with normal group.And the low-expression of VE-cadherin could be alleviated by UTI (0.032 ± 0.004 vs.0.061 ± 0.013,P =0.016).Conclusion The high permeability of EA.hy926 cells induced by TNF-α could be inhibited by UTI at the concentrations of 1-100 U/mL in a dose-dependent manner.

Objective To investigate the imaging and clinical features of Percheron artery infarction.Methods The clinical manifestations,imaging data,treatment,and prognosis of 10 patients with Percheron artery infarction were analyzed.Results All 10 patients had acute onset and had different degrees of consciousness disorders,including vertical gaze palsy (n =3),language disorder (n =3),limb weakness (n =6),and memory impairment (n =4).MRI showed bilateral thalamus infarction.Midbrain V-sign in one patient was observed.Cerebral angiography revealed that one patient had Percheron artery infarction.All 10 patients were improved and discharged,but left with varying degrees of sequelae.Conclusions Percheron artery infarction is rare in clinical practice.The diagnosis is mainly based on clinical manifestations and imaging examinations.Cerebral angiography can diagnose the disease.
