Objective To assess the characteristics of abdominal hernia and summarize the therapeutic efficacy of mesh plug tension-free hernioplasty in elderly ventral hernia. Methods All 207 elderly patients with abdominal hernia who were admitted to our hospital during January 1999 to December 2001 and received the mesh plug tension-free hernioplasty were analyzed retrospectively. Results There were 405 patients receiving the mesh plug tension-free hernioplasty from 1999 to 2001, in whom 207 had elderly ventral hermia. Among the 207 elderly patients, 144 had inguinal oblique hernia, 38 direct hernia, 11 direct and indirect hernia, 6 sliding hernia, 6 incisional hernia, 1 femoral hernia, and 1 femoral and inguinal direct hernia. Postoperative complications were urinary retention(8 cases), hypoincisional hematoma(4), scrotal hydroceles(1), and incisional infection (1). One hundred eithty-seven patients were followed-up for 4-40 months and no recurrence was found. Conclusions The mesh plug tension-free hernioplasty is of advantages for elderly abdominal hernia, such as simpleness in performance and a good therapeutic effect. It is especially suitable for the elderly patients due to less trauma and low recurrence rate. It is also important to pay attention to the postoperative complications to the elderly.

Objective To investigate the effect of Dl-3-n-butylphthalide on acute cerebral infarction.Methods In Department of Neurology in the Fifth Hospital of Wuhan from March 2013 to June 2014,100 cases of patients with first onset of acute cerebral infarction were recruited.The participants were divided into 2 groups (control group and treatment group) randomly,with 50 participants in each group.Besides general treatment,the patients of treatment group received intravenous injection of Dl-3-n-butylphthalide in acute phase and orally took soft capsule of Dl-3-n-butylphthalide in recovery phase.All the patients were followed up for 24 weeks.Neurological function and general cognition were assessed separately by national institute of health stroke scale (NIHSS),and mini mental state examination (MMSE) was applied to assess overall cognitive function.Results NHISS score was gradually decreased and MMSE score was increased in both groups.As compared with the control group,NIHSS score and MMSE score were changed significantly in the treatment group.From first onset to 24 weeks after treatment,NHISS score was decreased by 30％ in the control group and 44％ in the treatment group;MMSE score was increased by 17％ in the control group and 32％ in the treatment group.Conclusion Sequential therapy with Dl-3-n-butylphthalide improves neurological function and general cognition faster and more significant for patients with acute cerebral infarction.

ObjectiveToanalyzetheclinicalandimagingcharacteristicsinpatientswithcarotidsteal syndrome ( CSS ) and to investigate its compensatory pathw ays, diagnosis, and treatment. Methods The medical history and imaging data of the patients with CSS were colected. Their vascular lesions, colateral circulation, treatment, and prognosis w ere analyzed. Results A total of 11 patients w ith CSS (8 males and 3 females, mean age 66.7 ±5.1 years) were enroled in the study. Their clinical manifestations were posterior circulation transient ischemic attack (TIA) ( n=9, 81.8%), posterior circulation infarction ( n=1, 9.1%), and anterior circulation TIA ( n=1, 9.1%). A total of 19 pathological arteries w ere found:12 (63.1%) w ith occlusion, 2 (10.5%) w ith subtotal occlusion, 4 (21.0%) w ith severe stenosis and 1 (5.2%) w ith artery dissection. Seven patients (63.6%) w ere bilateral internal carotid artery lesions, 3 (27.2%) w ere unilateral bilateral internal carotid artery lesions, and 1 (9.1%) w as bilateral common carotid artery occlusion. Eleven patients had primary col ateral circulation, including posterior communicating artery patency in 10 patients (90.9%) and anterior communicating artery patency in 1 patient (9.1%). Four patients (36.3%) had secondary col ateral circulation and 1 (9.1%) had tertiary col ateral circulation. Al patients w ere treated w ith medication on the basis of the management of risk factors. Three patients w ere treated w ith stenting and tw o were treated with carotid endarterectomy. No stroke occurred in al patients during folow -up til September 2014. Conclusions The vascular lesions of patients w ith CSS often occur in the extracranial segment of internal carotid artery. Usual y the compensatory blood is through the circle of Wil is. The presentation is ischemia in the stolen arteries. Its diagnosis needs to be examined by digital subtraction angiography. On the basis of medication therapy, some patients may be treated w ith surgery or endovascular intervention.

Objective To investigate the correlation between posterior neck pain and lumbar epidural pressure (LEP)during percutaneous endoscopic lumbar discectomy (PELD).Methods A prospective study was performed on 86 patients undergoing PELD,46 males,40 females,aged 1 9-71 years,with ASA physical status of Ⅰ or Ⅱ.Each patient received lumbar epidural anesthesia.Lum-bar epidural pressure (LEP)was monitored continuously through a lumbar epidural catheter which was connected to a pressure transducer.LEP before the operation (LEPbase ),LEP at the time of pos-terior neck pain (LEPpain )and maximal LEP (LEPmax )were recorded.Results Thirty patients (34.9%)complained of posterior neck pain during the procedure.The lowest LEPmax was 31.0 mm Hg,and the highest LEPmax was 77.0 mm Hg.The LEPmax in patients with neck pain [(60.6± 8.8)mm Hg]was significantly higher than LEPmax in patients without neck pain [(50.7 ± 9.5 ) mm Hg](P <0.01 ).Patients with higher LEPmax had higher probabilities of having posterior neck pain (P <0.01).Conclusion Patients with higher LEPmax had higher probabilities of having posterior neck pain.

Objective To analyze the cognitive changes and influencing factors in patients with lacunar cerebral infarction after carotid artery intervention therapy. Methods Sixty lacunar cerebral infarction combined with carotid stenosis patients treated with artery intervention therapy (intervention therapy group) and 68 lacunar cerebral infarction without carotid stenosis patients treated with drug therapy (drug therapy group) were selected. The neuropsychological test was completed at entry and 1, 6, 12 months after entry, and the results were compared with 60 healthy controls (control group). The cognitive changes were observed. The neuropsychological test included mini mental state examination (MMSE), Montreal cognitive assessment scale (MoCA) and cognitive field test. Results There were statistical differences in other scores except the Stroop test C section and Wechsler adult intelligence scale (WAIS-RC) picture arrangement subtest at entry in intervention therapy group and drug therapy group compared with control group (P<0.05). There were no statistical differences in the all scores at entry between drug therapy group and intervention therapy group (P>0.05). In intervention therapy group, the MMSE scores, MoCA total score, Rey-Osterrieth complex figure test (ROCFT), auditory verb learning test (AVLT), and the WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). MMSE score, MoCA total score, long-time delayed recall of ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, semantic category fluency test of performing function and digit span backwards subtest of WAIS-RC 6 months after entry were significantly better than those at entry:(27.8 ± 2.2) scores vs. (26.4 ± 1.9) scores, (20.7 ± 2.3) scores vs. (19.3 ± 2.0) scores, (12.4 ± 3.2) scores vs. (10.8 ± 2.6) scores, (54.3 ± 10.6) scores vs. (49.9 ± 10.9) scores, (12.4 ± 2.0) scores vs. (11.2 ± 2.8) scores, (12.9 ± 2.0) scores vs. (10.6 ± 2.6) scores, (17.5 ± 4.0) scores vs. (15.4 ± 3.4) scores and (4.0 ± 0.9) scores vs. (3.5 ± 0.9) scores, and there were statistical differences (P<0.05). In drug therapy group, there were no statistical differences in the all scores 1 and 6 months after entry, compared with that at entry (P>0.05);the MMSE score, MoCA total score, ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function and digit span backwards subtest of WAIS-RC 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). There were no statistical differences in all scores 12 months after entry between intervention therapy group and drug therapy group (P>0.05). In patients intervention therapy group, Logistic regression analysis showed that the MoCA score was related with age, hypertension and low education level (P<0.01 or<0.05), but was not related with smoking, diabetes and interventional treatment (P>0.05). Conclusions Cognitive impairment in patients with lacunar cerebral infarction and carotid stenosis is severe and extensive, but most cognition disorders can improve to normal level 12 months after artery intervention therapy.

Objective: To observe the feasibility and clinical curative effect of anatomical reduction and fixation of lesser trochanter through posterior-lateral approach for the treatment of comminuted femoral intertrochanteric fractures in elderly patients. Methods: A total of 19 cases with comminuted femoral intertrochanteric fracture, aged 60 to 84 years were enrolled in this study.According to Evans-Jensen classification, 13 cases had type Ⅱ B and 6 cases had type Ⅲ femoral fracture.Through the posterior-lateral approach, the lesser trochanter was fully exposed, reduced and fixed by screw.The proximal and distal femur were well fixed with dynamic hip screw(DHS)or proximal femoral locking plate(PFLP). The lesser trochanter reduction was observed by intraoperative vision and postoperative X-ray.The function evaluation after hip surgery was performed by using Sanders hip function score. Results: All 19 patients obtained the anatomic reattachment in the lesser trochanter.All patients were followed up for an average of 18 months.After treatment, the Sanders hip function score were excellent in 7 patients(36.8%), fine in 12 cases(63.2%). And curative efficacy was good in all cases(100%). There was no significant difference in the curative effect between patients with different classification and gender. Conclusions Through the posterior-lateral approach, the surrounding structures of the lesser trochanter can be fully exposed, and the lesser trochanter can be anatomically repositioned.The posterior-lateral approach to anatomical reduction and fixation of lesser trochanter is an effective and feasible method for the treatment of comminuted intertrochanteric fracture in the elderly.

Objective To analyze the basal conditions of 5 patients with cerebrovascular fibromuscular dysplasia (FMD),and explore the clinical presentation,imaging features,therapies and outcomes of cerebrovascular FMD.Methods Five patients with cerebrovascular FMD,admitted to our hospital from January 2012 to April 2013,were chosen in our study; their medical history and imaging features were collected,and their clinical presentation,imaging features,therapies and outcomes were retrospectively analyzed when combining with literature review.Results Five patients all presented with stroke,including four having hemiplegia as the initial symptom,and one having headache with nausea and vomiting as the main performance.One was diagnosed as having subarachnoid hemorrhage by CT scan,and four had different infarction lesions in lobes and basal ganglia on MRI.Artery dissection was discovered in all patients by cerebral digital substraction angiography,including two with right internal carotid artery dissection,one with right vertebral artery dissection combined with aneurysm in anterior communicating artery associated with "string-of-beads" appearance on C1 segment of right internal carotid artery and left vertebral artery,one with bilateral vertebral artery dissection,and the last one with bilateral internal carotid artery dissection and moyamoya disease-like vessels.No abnormality was discovered in two patients by renal artery angiography.The patient with anterior communicating artery aneurysm was treated with endovascular aneurysm embolization,having poor prognosis.In the remaining 4 patients with cerebral infarction,two were treated with carotid artery stenting,and the other 2 were only given antiplatelet therapy.No patient suffered cerebrovascular accidents during the 12-month follow-up.Conclusions Cerebrovascular FMD is a rare cause of young stroke,and patients with cerebrovascular FMD often manifest headache,neck bruit,carotid artery dissection and stroke.It is particularly important to make definitive diagnosis by performing cerebrovascular imaging examinations and give treatment accordingly.The long term outcome of FMD is not clear now.

The humoral immune response of B cells is the key to the protection of specific immunity, and immune aging reshapes its production and function. The decreased B cell immune function is an indicator of immune senescence. The impaired humoral immune function mediated by antibody secreted by B cells leads to a decline in the response of elderly individuals to the vaccine. These people are therefore more susceptible to infection and deterioration, and have a higher incidence of tumors and metabolic diseases. Activation-induced cytidine deaminase (AID) is an enzyme that triggers immunoglobulin class conversion recombination (CSR) and somatic high frequency mutation (SHM). It decreases during immune senescence and is considered to be a biomarker of decreased B cell function in aging mice and humans. Understanding the inherent defects of B-cell immune senescence and the regulation mechanism of AID in the aging process can provide new research ideas for the susceptibility, prevention and treatment of diseases in the elderly.

Objective To evaluate the incidence, prognosis and influencing factors of lower cranial nerve palsy after microvascular decompression (MVD) in patients with hemifacial spasm (HFS). Methods Clinical data of 1033 patients with HFS, admitted to our hospital from May 2014 to August 2016, were retrospectively analyzed. The incidence of lower cranial nerve palsy after procedure and prognosis of these patients were summarized; and influencing factors were analyzed by statistical method. Results In 1033 patients with HFS, 10 patients (0.97％) had lower cranial nerve palsy after procedure: 6 patients suffered hoarseness, 2 patients suffered dysphasia, and 2 patients were with both symptoms; the symptoms in 6 patients completely recovered within one month, 2 patients within one-3 months, and 2 patients within 3-6 months. No permanent low cranial nerve palsy occurred. There were no statistical significances in age, gender, clinical course, sides, or the types of offending vessels between the lower cranial nerve palsy patients (n=10) and the non-palsy patients (n=1023)(P>0.05). Conclusion Lower cranial nerve palsy is a rare complication after MVD, and type of responsible vessels is not a influencing factor in this complication

Objective　To investigate the changes of serum α-synuclein and white matter structure in Parkinson’s disease patients with different status of cognitive impairment,and to explore the relationship between α-synuclein,changes of white matter structure and cognitive impairment in Parkinson’s disease.Methods 　Sixty patients with Parkinson’s disease were selected and divided into 3 groups according to their cognitive function:the normal cognitive group (PD-N),mild cognitive impairment group (PD-MCI) and dementia group (PDD).Patients with cognitive impairment were assessed with the MMSE and the MoCA.All cases were scanned with routine MRI sequence and diffusion tensor imaging (DTI) sequence.Fractional anisotropy (FA) were measured.The serum levels of α-synuclein were measured by ELISA.Results　The FA values of right temporal lobe,right cingulate posterior bundle,the genu of corpus callosum in PD-M CI group were lower than that in PD-N group (all P<0.05),the same findings were found regarding the FA values of left occipital lobe,left cingulate anterior bundle and the splenium of corpus callosum in the PDD group (all P<0.05).Analysis of logistic regression equation revealed that the genu of corpus callosum might be specific for the brain white matter;and so did left cingulate anterior bundle.The Spearman correlation analysis showed that there was a negative correlation between FA values of left frontal lobe and MoCA total score in PD patients,as well as right temporal lobe,left occipital lobe,left cingulate anterior bundle,right cingulate anterior bundle and the splenium of corpus callosum (all P<0.05),positively correlated between serum α-synuclein concentration and MoCA total score in PD patients (P<0.05).Conclusion　Diffusion tensor imaging might be valuable for the diagnosis of cognitive dysfunction in PD;and there might be a certain relationship between serum α-synuclein and cognitive impairment in Parkinson’s disease.
