OBJECTIVE: To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation. METHODS: The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded. RESULTS: All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation ( P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients' satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level. CONCLUSION Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.

Objective:To investigate the clinicopathological characteristics, treatment methods and prognosis of renal primary neuroendocrine neoplasms.Methods:The clinical data of 42 patients with renal neuroendocrine neoplasms admitted to the First Affiliated Hospital of Zhengzhou University from October 2011 to June 2021 were retrospectively analyzed.There were 17 males and 25 females. The median age was 60.0 (50.0, 67.0) years old.The CT enhancement scan lesion was slightly intensified with less intensification than normal renal parenchyma.The clinic manifestation included lumbar abdominal pain in 7 cases, hematuria in 3 cases, abdominal distension in 1 cases, and asymptomatic in 8 cases. The average diameter of tumor was 8.0 (4.0, 10.0) cm. The tumor of 13 cases was in the left, and 6 cases was in the right. 6 cases were in T 1 stage, 11 cases were in T 2, 11 cases were in T 3, and 14 cases were in T 4.17 cases had lymph node metastasis, 11 cases had distant metastasis.The surgical method was radical nephrectomy in 27 cases, nephrectomy in 5 cases and interventional embolization in 4 case, and no operation in 6 cases, including 5 with chemotherapy alone and 1 with supportive care.Patients were classified by WHO Classification of renal tumors of the urinary system and the male reproductive organs (2016) into high-differentiated renal neuroendocrine tumors (NET, including carcinoid and atypical carcinoids) and high-grade renal neuroendocrine carcinoma (NEC, including small cell neuroendocrine carcinoma and large cell neuroendocrine carcinoma). The clinicopathological characteristics and prognosis of the 2 groups were compared, and the Cox proportional regression risk model was used to analyze the clinical factors affecting the prognosis. Results:In the NET group, 12 cases were carcinoids and 7 cases were atypical carcinoids. In the NEC group, 23 cases were small cell carcinomas.The mean Ki-67 index of 42 cases was 35% (4.5%, 62.5%). The proportion of positive expression of the neuroendocrine markers CD56, chromogranin A (CgA), and synapsin (Syn) were (37/42), (15/42), and (38/42), respectively. A total of 42 patients were followed up, and the median follow-up time was 60 (35, 99) months, and the median survival time was 25 (15, 60) months. The 3-year and 5-year overall survival rates were 40.0% and 21.2%. The 3-year and 5-year overall survival rates in the NET group were 72.6% and 42.3%.The 3-year and 5-year overall survival rates in the NEC groups were 6.3% and 0, respectively. The mean Ki-67 index was 3% (2%, 10%) in the NET group, 2 patients received postoperative chemotherapy and 3 patients had early progression after initial treatment.The mean Ki-67 index in the NEC group was 60% (40%, 80%), 15 patients received postoperative chemotherapy, and 13 patients had early progression of initial treatment.There were statistically differences in treatment method, postoperative chemotherapy, Ki-67 index, and early disease progression (all P <0.05) between the two groups.The results of univariate analysis showed that sex, age, early progression, treatment method, tumor differentiation, and Ki-67 index were all factors influencing patient prognosis (all P <0.05). Cox multivariate analysis showed that poorly differentiated NEC ( HR=13.964, P=0.003) and early progression ( HR=3.626, P=0.018) were independent risk factors for patient survival, and renal radical surgery ( HR=0.197, P=0.033) was independent protective factors for patient survival. Further subgroup analysis showed that the median survival time of the NEC patients with adjuvant chemotherapy after surgery was significantly longer compared with the patients without adjuvant chemotherapy (21 and 9 months, P=0.012). Conclusions:Primary renal neuroendocrine tumors are clinically rare, often manifested as lumbar and abdominal pain, and radical renal surgical treatment is preferred.The NET has a better prognosis and NEC prognosis is extremely poor, but NEC patients can have survival benefit from chemotherapy. NEC and early progression of the disease are independent prognostic risk factors, and radical renal surgical treatment is an independent protective factor for prognosis.

Objective:To assess the feasibility of free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection in patients with supratentorial intracerebral hemorrhage (sICH), and to evaluate the accuracy of catheter placement.Methods:Fifty-two sICH patients received free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection in our hospital from January 2018 to December 2019 were chosen (free-handed conical craniotomy group); 30 sICH patients received frameless stereotactic puncture and drainage at the same time period were selected (stereotactic puncture group). The clinical data of these patients were retrospectively analyzed. The CT results were analyzed, and differences of relative error (RE) as the indicator of catheter placement accuracy were compared between the two groups.Results:Mobile CT was successfully performed in all patients from free-handed conical craniotomy group, and sufficient information was provided for surface projection in all patients. The percentages of patients with satisfactory results of catheter placement (RE<1) in the free-handed conical craniotomy group and stereotactic puncture group were 92.3% and 90.0%; one patients from the free-handed conical craniotomy group had repeated puncture. There was no significant difference in postoperative RE between the two groups (0.52±0.33 vs. 0.53±0.29, P>0.05). Subgroup analysis of different hematoma locations and volumes also showed no statistically significant difference in postoperative RE ( P>0.05). Conclusion:Free-handed conical craniotomy and drainage guided by novel 16-slice mobile CT-assisted surface projection is feasible in sICH patients, and the accuracy of catheter placement is similar with frameless stereotactic puncture and drainage.

Intracranial venous sinus thrombosis is a special type of cerebral vascular disease. It usually originates from the later period of wasting disease, brain trauma, puerperium, blood disease, heart disease, eye/nasal/facial infection, meningitis and septicemia. It occurs in different age and sex. Infants, young children, frail elderly people, postpartum women, chronic disease patients are prone to be affected.Because of lacking of typical clinical manifestations, the clinical diagnosis and treatment of this disease is difficult and easily leading to misdiagnosis and mistreatment, which affects the prognosis of the patients.Because of lacking of standardized diagnosis and treatment strategy, different methods are needed. According to the proceeding reports, we reviewed the current progress of the diagnosis and treatment of intracranial venous sinus thrombosis.

OBJECTIVETo evaluate the efficacy and safety of mechanical thrombectomy with the Solitaire AB device in recanalization of patients with acute ischemic stroke of posterior circulation.

METHODSThe clinical data of 17 consecutive patients with acute ischemic stroke of posterior circulation, treated with the Solitaire AB device from August 2011 to August 2015 in Department of Neurosurgery, the Military General Hospital of Beijing People's Liberation Army, were extracted and then retrospectively analyzed. There were 12 male and 5 female patients with a median age of 60 years (ranging from 44 to 75 years). Among them, 8 cases occluded in basilar artery, 4 cases occluded in vertebral artery and 5 cases occluded in vertebral plus basilar artery. Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after treatment, measured by National Institute of Health stroke scale (NIHSS) score, were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after treatment.

RESULTSFifteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath time were above 7.5 hours. The NIHSS score at 7 days was 11±10, which was significantly decreased compared to the admission NIHSS score 17±5 (t=2.949, P=0.009). No symptomatic intracranial hemorrhage case was found after thrombectomy. At 90 days, one patient died(mRS 6), one patient seriously disabled (mRS 5), two patients moderately seriously disabled (mRS 4), four patients resulted in moderate outcome (mRS 3) and the other 9 patients achieved good outcome (mRS 0 to 2). The dead and seriously disabled cases were both due to failure in recanalization. Two moderately seriously disabled cases were probably attributed to their severe admission condition (NIHSS >20) and prolonged time (onset to sheath time >6 hours).

CONCLUSIONMechanical thrombectomy with the Solitaire AB device contributes to a high rate of recanalization with a low probability of complication and improves functional outcome in patients with acute ischemic stroke of posterior circulation.

Objective To explore the intra-arterial therapies and prognostic predictors of anterior circulation stroke patients.Methods Fifty-nine anterior circulation stroke patients,admitted to our hospital from May 2011 to June 2014,were divided into two groups:intra-arterial therapy (IAT) group (n=25,thrombolysis in myocardial infarction [TIMI] grade Ⅱ～Ⅲ after IAT) and multi-modal therapy (MMT) group (n=34,onset time longer than 6 h or achieving no good effect afterIAT);their clinical data and follow up data were reviewed and summarized.National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity;and modified Rankin scale (mRS) was performed three months after the stroke to reveal the clinical outcomes.The t test,chi-square test and multivariable Logistic regression analysis were performed to analyze the related prognosis factors.Results The mean age of the patients was 59.8±1.3 years.MMT patients had significantly higher baseline admission NIHSS scores as compared with those inIAT patients (18.3±4.2 vs.12.6±4.3,t=l 1.88,P=0.000);MMT patients had a significantly higher patent flow rate as compared withIAT patients (82.4％ vs.56.0％,x2=4.878,P=0.027).Besides,the MMT patients had a significantly longer time till accepting treatment (5.8±1.4 vs.5.3±0.9,t=4.735,P=0.000);In multivariate analysis,age,time getting treatment,NIHSS scores at discharge are predictors for poor outcomes,while perfect recanalization was associated with favorable outcome.Conclusions MMT can be used for patients with severe admission NIHSS scores,and it may enjoy higher patency rate than IAT.Good vessel recanalization is the only predictor for favorable outcome.

Objective To observe the influence of carotid endarterectomy in cognitive functions of patients with symptomatic carotid stenosis.Methods Forty-three patients admitted to our hospital and performed carotid endarterectomy from February 2013 to August 2014, were enrolled in the study.Cognitive functions of the patients were evaluated by Montreal cognitive function assessment (MoCA) and cerebral blood flow (CBF) by cerebral perfusion CT scan three days before and three months after operation, respectively.According to the MoCA scores after operation, the patients were divided into significant improvement group and non-significant improvement group, and their cerebral hemodynamics indexes were compared.Results (1) As compared with those before operation (24.1±2.2, 0.97±0.08), the MoCA scores (26.02±2.9) and relative cerebral blood volumes (rCBV, 1.00±0.08) three months after operation were significantly different (P＜0.05).(2) The postoperative relative CBF, rCBV and relative mean transmit time in the significant improvement group were significantly improved as compared with those preoperative indexes (P＜0.05);whereas, these values in the non-significant improvement group didn't show significant difference between preoperative and postoperative indexes(P＞0.05).Conclusion Carotid endarterectomy may help to improve the cognitive function in those patients with symtompatic carotid stenosis, and the effect might be associated with the improvement of cerebral perfusion.

Objective To explore the clinical efficacy and safety of hyper-early embolotherapy in treatment of intracranial ruptured aneurysm.Methods A retrospective analysis was made on 33 patients with intracranial ruptured aneurysm.Preoperative Hunt-Hess grade:grade Ⅰ-Ⅱ in 16 patients,gradeⅢin 5 patients,grade Ⅳ in 9 patients,grade Ⅴ in 3 patients.All patients were confirmed with subarachnoid hemorrhage (SAH) by angiography and then underwent embolization under general anesthesia by detachable coils within 6 h from onset.Results After operation,25 patients (75.8％) recovered well,4 patients (12.1％) were with mild disability with paralysis and aphasia,4 patients (12.1％) were dead (1 patient for intraoperative aneurysm rupture,1 patient for postoperative pneumonia,1 patient for infection of hematoma at puncture site and 1 patient for postoperative gastrointestinal bleeding).Followed up 1-6 months,no rebleeding occurred.Conclusions Hyper-early embolotherapy could avoid rebleeding of the aneurysm,and relieve the vasespasm,without increasing the intra-operative rebleeding rate.Moreover hyper-early embolotherapy could greatly decrease the mortality of poor-grade SAH patients.

Objective To explore the method and management of pre-hospital care and raise the level of traffic injuries in pre-hospital care by summarizing the clinical features of death patients with severe tragic accident trauma Methods The basic data of 62 death patients with severe traffic accident trauma was analyzed according to death report statistics of severe traffic accident trauma from January 1st,2005 to December 31th,2008 Results Brain injury death accounted for most of traffic accident trauma death.The mortality rate of brain injury in the wounded wag 8.28%(13/157),but of asphyxia and hemorrhagic shock was 2.55%(4/157),3.18%(5/157)respectively in 2005.With the development of treatment and rescued in time, the mortality rate reduced to 6.11%(11/180),0,0.56%(1/180)in 2008.Conclesions It should be trying to shorten the time of pre-hospital care for pafients with trsffic accident trauma,especially in patients combined with hemorrhagic shock,asphyxia,severe brain injury.It is concluded that rapid and effective pre-hospital care can significantly reduce death rate and self-help or each other rescue training would also be effective to reduce mortality.

In order to compare the clinical characteristics of familial and non-familial bullous lichen planus (BLP), the archival data of 36 BLP patients with positive family history and 21 BLP patients with negative family history diagnosed according to the clinical features and histopathology were collected in our department from 1956 to 2003. The clinical features were analyzed and compared. There were significant differences between familial and non-familial BLP in age of onset, duration of disease and extension of eruption (P＜0.01). It was concluded that familial BLP appeared to differ from the non-familial form in its earlier age of onset, longer duration of the disease, more extensive eruption and more tendency to involve nails. Hereditary factors may play a role in the pathogenesis of familial BLP.
