Objective To explore the extrahepatic bile duct stones after reoperation cause analysis and coun-termeasures.Methods Clinical data of 150 patients with liver surgery gallstone surgery again were retrospectively analyzed,according to the first reason for liver from gallstone surgery will be divided into the three groups:group hepa-tolithiasis ( group A,100 cases) ,gallstones group ( group B,30 patients) ,common bile duct stones group ( group C, 20 cases) .The reasons for reoperation were analyzed.Results In intrahepatic bile duct stones reoperation patients, the recurrence of liver gallstones was 98 cases(65.3%),common bile duct cysts and Caroli disease was 35 cases (23.3%),anastomotic stenosis in 17 cases(11.3%);The postoperative complication rate of group A(44.0%) was significantly higher than that of group B(13.3%) and group C(15.0%)(χ2 =9.32,5.88,all P<0.05);The sec-ondary and post-operative inflammation stone recurrence within 5 years of group A was 32.0%,which was significant-ly higher than 6.7%of group B and 10.0%of group C(χ2 =7.67,3.97,all P<0.05).Conclusion The intrahe-patic bile duct stones are the main types of reoperation after liver gallstones,gallstones and liver recurrence is the main cause of its secondary surgery.It should be make clear the disease cause of preoperation, take a different surgical options for patients with different types of stones,prevention,and avoid the occurrence of postoperative complications, which can effectively reduce the risk of secondary surgery to alleviate the suffering of patients.

Objective: To observe the efficacy of mirtazapine in the treatment of depression after cerebral infarction and its effect on rehabilitation of neurological functions. Methods:117 patients with acute cerebral infarction comorbid with major depression were randomly allocated to two groups treated with mirtazapine (57 cases) or not (60 cases). Hamiltion Depression Rating Scale (HAMD), Zung's Self-rating Depression Scale(SDS), modified Edingburgh-Scandinavian Stroke Scale (SSS) and Activity of Daily Living(ADL) were measured at baseline, 2 weeks, 4 weeks, 8 weeks and 6 months after randomization.Results:At the end of 6 months trial, the effective rate for depression of mirtazapine group was 100%, including 41 with relief (41/57, 71.9%); while that of control group was 13.4% (3/60), with only 4 with relief (6.7%). For neurological function, 78.9% (45) patients in mirtazapine group had significant improvement, that number in control group was 31 (51.7%). From the third week, patients in mirtazapine group had better ADL results than baseline (31.2?11.2/39.2?15.8), at the end of 6 months, their activity of daily life was much better than that of control (15.7?5.4/21.8?9.7, t=4.17,P

Objective To observe the effects of levodopa on verbal and spatial working memory in elderly patients with Parkinson's disease (PD).Methods The modified Smith working memory software were applied to study the verbal and spatial working memory in 32 PD patients before and 8 weeks after treatment with levodopa and benserazide hydrochloride tablets.The results of PD patients were compared with those in 32 normal controls matched for age,sex and education.Results The correct rates of phonological verbal and coordinate visuospatial working memory were significantly lower in the PD patients without treatment than in the normal controls (both P＜0.01).The correct rates of semantic verbal and categorical visuospatial working memory had no significant differences between the PD patients without treatment and the normal controls (both P＞0.05).The correct rates of phonological verbal working memory and coordinate visuospatial working memory were significantly higher in the PD patients after administration of levodopa and benserazide tablets than in PD patients without treatment [(88.6±6.5)％ vs.(82.1 ± 6.6)％,(84.2±8.8)％ vs.(75.2±8.9)％,respectively,both P＜0.01],but there were no significant differences in the correct rates of semantic verbal working memory and categorical visuospatial working memory between the above two groups (both P＞0.05).The correct rates of phonological verbal,semantic verbal,coordinate visuospatial and categorical visuospatial working memory were negatively correlated with the course of disease,and had no correlations with age and the degree of education.Conclusions Levodopa can improve the functions of phonological verbal working memory and the coordinate visuospatial working memory,but has no effect on the semantic verbal working memory and the categorical visuospatial working memory.It is postulated that dopamine replacement therapy may have double dissociable effects on the different working memories.

Objective To study the clinical features and surgical strategies of thoracic spinal stenosis caused by ossification of posterior longitudinal ligament(OPLL).Methods From January 2004 to March 2009,21 cases of thoracic spinal stenosis casued by OPLL,including 13 males and 8 females,received surgical treatments.Those cases aged from 34 to 71 years,with an average of 51.2 years old.The courses of disease were from 2 to 50 months,averaged 11 months.The lesions located in upper thoracic(T1-T4)for 4 cases,in middle thoracic(T5-T8)for 7 cases,in lower thoracic(T9-T12)for 10 cases.Nine cases were associated with ossification of ligamentum flavum(OLF),and 8 cases combined with cervical OPLL.Eleven cases received laminectomy and 10 cases received anterolateral decompression.Results The operation time was 90 to 240 min for posterior laminectomy with an average of 140 min,and 110 to 360 min for anterolateral decompression with an average of 240 min.All cases had no worse postoperative symptoms,neurological complications,subarachnoid cavity or wound infection.Japanese Orthopaedic Association(JOA)score was 8 to 15 with an average of 9.17±1.63 in 6 months after surgery.Nerve function improvement was excellent for 8 cases,good for 6 cases,fair for 5 cases and poor for 2 cases.The excellent and good rate was 66.7%.JOA score was 8-15,averaged 10.23±1.64,in 12 months after surgery.Nerve function improvement was excellent for 8 cases,good for 7 cases,fair for 4 cases,and poor for 2 cases.The excellent and good rate was 71.4%.Conclusion Thoracic spinal stenosis result from OPLL,which often combine with cervical OPLL and OLF,often show multiple manifestations.Posterior laminectomy and anterolateral decompression are suitable for those conditions.

Objective To explore the characteristics of event-based prospective memory (EBPM) and time-based prospective memory (TBPM) impairments in patients with Parkinson's disease (PD). Methods EBPM and TBPM were examined in 87 PD patients and 85 healthy controls. And both of them were divided into two groups: aged group (≥60 years old) and non-aged group (＜60 years old). Results (1) The scores of EBPM were significantly lower in aged PD patients and non-aged PD patients than in age-matched control groups [(2. 5±0. 4) vs. (5.8± 1.3),(3.9±2.4) vs. (6.3±1.5), both P＜0. 01]. There were no significant differences in the scores of EBPM between aged PD patients or non-aged PD patients and their age-matched control groups [(3.6±0.5) vs. (3.8±0.8), (4.8±0.9) vs. (4.9±0.9), both P＞0.05]. (2)The Hoehn-Yahr grade in PD patients was significantly correlated with scores of EBPM, but not with scores of TBPM.Conclusions The patients with PD have an impairment in EBPM, but not in TBPM. The impairment of EBPM may be related to the disease severity of PD.

Objective To explore the surgical strategies of thoracic spinal stenosis with dural ossification. Methods One-hundred and eight patients with thoracic spinal stenosis were treated. Dural ossification was found in 29 cases during operation from January 2004 to June 2008. There were 19 males and 10females, with an average age of 56.4 years (42-74 years). The course of disease was 13 months (2-48months). The lesion was located in T1-T4 in 4 cases, T5-T8 in 5 cases, and T9-T12 in 20 cases. All the patients were treated by posterior lamina resection. Both ossificated dural and ossificated yellow ligament were resected in 16 patients. Decompression was performed with partial ossification remaining on dural surface in 13 cases. JOA score was used to evaluate the outcomes 1, 3 and 12 months after operation. Results The average operation time was 140 min, and average bleeding was 300 ml. Dural incisions were repaired with a wound drainage in 11 cases. Seven cases appeared cerebrospinal fluid leakage which healed in 3-5 days.Dural incisions were not repaired without wound drainage in 5 cases. Cerebrospinal fluid leakage occurred in these cases healed in 5-7 days. Thirteen cases treated with floating method did not appear cerebrospinal fluid leakage. All patients did not undergo subarachnoid infection and the aggravation of original nervous system symptoms. According to JOA score, all patients were evaluated as excellent in 22 cases, good in 5 and fair in 2 cases, and excellent and good rate was 93%. Conclusion For thoracic spinal stenosis with dural ossification, resection of both ossificated dural and ossificated yellow ligament and complete decompression with partial ossification remaining on dural surface is safe and reliable. Dural ossification does not influence the prognosis, but increase operative difficulty and risk.

Objective To investigate the selection of surgery and clinical outcomes of upper cervical injuries.Methods 25 upper cervical injury patients were involved in this retrospective study from November 2011 to June 2014.Including 20 males and 5 females with mean age of 37.1 years old (range,14-55 years old).Individual operation methods were based on the comprehensive evaluation of specific situations including the clinical manifestation,the type of the injuries and the imaging data.HaloVest distraction was applicated before operation.The surgery by anterior approach were performed for 7 patients and posterior approach were performed for 18 patients.Preoperative and postoperative American Spinal Injury Association (ASIA) grade and Functional Independence Measurement (FIM) score were studied to evaluate the nerve functional restoration.Imaging data before and after the operation were contrasted to evaluate the reduction of the fracture,the bone union,the fusion of the bone graft and the condition of the internal fixation.Wilcoxon Singed Rank Test was applied to compare the FIM score between pre-operation and last follow-up.Results 15 patients presented neurological function deficit because of cervical spinal cord compromise.All cases were followed up for 6-35 months (mean 18.2 months),showing good clinical and radiological effects.Solid fusion was obtained in all patients among 3-12 months.The ASIA grade improved by an average of 1.1 (6 months after operation) and 1.2 (12 months after operation).There was significant difference in FIM score between pre-operation and last follow-up.One patient got cerebrospinal fluid leakage.Conservative treatment was implemented with the Trendelenburg position,rehydration fluids and so on.Removal of drainage tube 8 days later when the drainage was less than 30 ml/24 h.No incision infection,cerebrospinal fluid leakage,migration or breakage of internal fixation was observed at the last follow-up.Conclusion The type of upper cervical injuries are complicated,the characteristics of fracture,dislocation and nerve injury in different patients are different.The specific situation should be evaluated comprehensively to make individual operation methods.The success of the operation requires the proficiency of the anatomic basis,the biomechanical characteristics,precise entrance point and direction in operation,appropriate diameter of the screw and suitable depth of the screw road.

Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.
