The control group received traditional nursing,the experiment group received specific nursing. The quality of life was surveyed by SF-36 Scale and Olson Marriage Quality Test. [Result]The quality of life of experiment group was improved significantly(P

Objective To summarize countermeasures on common problems of microendoscopic discectomy(MED). Methods Microendoscopic discectomy was performed in 104 cases of lumbar disc herniation by using the MED system(Sofamor Danek Group,USA).Frequently encountered problems during the operation were reviewed and summarized. Results Conversions to open surgery were required in 4 out of 104 cases due to bleeding or adherence.Among the rest of 100 cases,dural injury occurred in 3 cases,with 1 case accompanying leakage of cerebrospinal fluid.Of the 100 cases(115 intervertebral spaces),the average operation time was 50 min(range,30~90 min) and the average hemorrhage amount was 80 ml(range,20~400 ml) for each intervertebral space.The 100 cases were followed for 3~32 months(average,18 months).According to the Macnab criteria,the curative effects were classified as excellent in 65 cases,good in 29 cases,and fair in 6,the rate of excellent or good effects being 94.0%(94/100). Conclusions The most frequent problems during MED are bleeding and prolonged excision of the ligamenta flava.Strict adherence to technique,acquaintance with the weakness of the ligamenta flava,and familiarity with anatomic structures of the vertebral vein system and its relationship with abdominal pressure,are very important in the prevention and treatments of surgical complications.

Objective To investigate the expression and significance of MMP-3 in knee joint synovium of different stage in osteoarthritis (OA) patients. Methods MMP-3 protein were detected by immunohistochemical method in knee synovial tissues from 90 OA patients (the OA group) and OA group was divided into 3 subgroups according to Kellgren and LawrenceX-ray diagnosing standards: the gradeⅠ(n = 30), gradeⅡ (n = 30) and grade Ⅲ subgroups (n = 30). 30 patients were enrolled as control group. Immunohistochemistry was used to detect the expression of MMP-3 protein in the tissue. Results The expression level of MMP-3 protein in OA group was significantly higher that in the normal synovium (P < 0.05). There existed significant difference in the expression of MMP-3 protein between the grade Ⅲ subgroup and the gradeⅠ, or Ⅱsubgroups (P < 0.05). The expression of MMP-3 protein related positively to the severity of OA (r = 0.912, P < 0.05). Conclusion The expression of MMP-3 protein related closely to the pathogenic mechanism of OA. It may serve as an important indicator of early diagnosis and the activity of OA.

Objective To provide therapeutic strategy by investigating the anxiety and depression status as well as the correlated impact factors in patients with chronic prostatitis. Methods The self-rating anxiety scale (SAS)and self-rating depression scale (SDS)were employed to evaluate psychological response of 360 patients with chronic prostatitis. Results Both the average scores of SAS and SDS in patients with chronic prostatitis were higher than normal levels of Chinese population. The impact factors for anxiety included income status, educational level and disease course. Conclusions The mental health status of chronic prostatitis patients is poor and certain factors affect the occurrence of anxiety and depression. Therefore, it is necessary to treat the patients with supportive psychotherapeutic intervention and with combined approaches.

Objective To analyze the effect of mesporous calcium silicate (m-CS)/calcium sulfate cement (CSC),m-CSC for short,in bone defect repair.Methods Setting time and compressive strength of the m-CSC (15 m-CSC as group Ⅰ and 30 m-CSC as group Ⅱ) were tested.CSC was used as the control.Cement samples were immersed in Tris-HCl solution,andin vitro degradation of the m-CSC was measured.Cell morphology and cell proliferation as well as differentiation on the samples were assessed.The cements were implanted into the traumatic femoral defects in rabbits,and the in vivo degradability and osteogenesis of the cements were investigated by histological evaluation after implantation for 4,8 and 12 weeks.Results Addition of m-CS into CSC prolonged the setting time (7.8 min in group Ⅰ and 10.5 min in group Ⅱ),obviously longer than 3.7 min in control group and did not have obvious effect on compressive strength of the cements.Weight loss of m-CSC solution was obviously lower (61.8 wt％ in group Ⅰ and50.3 wt％ in group Ⅱ),compared to70.4 wt％ in control group,pH value in group Ⅱ decreased from 7.40 to 7.26,while decreased from 7.40 to 6.86 in control group,m-CSC could promote cell proliferation and differentiation compared to CSC.At postoperative 12 weeks,histological sections showed massive new bony tissue (55.2％) in group Ⅱ,obviously higher than 25.6％ in control group.Conclusion m-CSC exhibits good biocompatibility,degradability and osteogenesis,and can promote bone regeneration in bone defect repair.

ObjectiveTo investigate the effectiveness and toxicity of CyberKnife in the treatment of lung metastases.MethodsTreatment details and outcomes were reviewed for 93 targets of 48 histologically verified patients treated by CyberKnife at the CyberKnife Center of Tianjin between September 2006 and June 2010.The median tumor volume was 6.0(0.2 - 135.2) cm3,the median biological equivalent dose was 140.8(53 - 180) cGy (α/β =10),the median fraction was 3(1-7) times and the median isodose line was 81％ (71％-91％ ).ResultsThe rate of follow-up is 96％.33 cases were followed up for more than 2years.The effective rate was 90.3％.Two targets of 2 patients locally progressed.The 1-and 2-year local control rates,overall survival (OS) rates and progression-free survival (PFS) rates were 98％ and 98％,83％ and 63％,and 64％ and 37％,respectively.Univariate analyses showed that age older than 60 versus ≤60 years tended to be predictor for PFS ( x2 =3.45,P =0.063 ) ;The PFS of patients who had single lesion was better than patients with multiple lesions ( x2 =4.49,P =0.034 ) ; patients with disease-free interval longer than 18 months had better OS ( x2 =6.50,P =0.011 ).Five patients were reported to experience treatment-related grade 1 radiation pulmonary injury,and one each for subcutaneous fibrosis with pigmentation,grade 2 and grade 3 adverse event.ConclusionsFor patients with lung metastatic lesion,CyberKnife is an effective option with high local control rate and little acute reaction.The long-term outcome and toxicity need further study.

Objective To investigate the pathogen distribution and risk factors of pulmonary infection after acute cervical spinal cord injury (ACSCI) in an attempt to offer reference for early antiinfection therapy.Methods The study comprised 223 cases who were admitted from October 2011 to October 2014.There were 149 males and 74 females,at (43.3 ± 13.5) years of age.Species of pathogens identified were gram-positive,gram-negative and mixed.Effects of age,gender,injury types and tracheotomy on pathogen distribution were analyzed.Results Gram-negative infection was found in 114 cases (51.1％),with tracheotomy accounting for 7.0％ of the cases and death accounting for 1.8％ of the cases,and the main causative pathogens were Klebsiella pneumonia,Escherichia coli,Pseudomonas aeruginosa and Acinetobacter baumannii.Gram-positive infection was found in 41 cases (18.4％),with tracheotomy accounting for 12.2％ of the cases and death accounting for 7.3％ of the cases,and the main causative pathogens were Staphylococcus aureus and Streptococcus pneumonia.Mixed infection was found in 68 cases (30.5％),with tracheotomy accounting for 22.1％ of the cases and death accounting for 13.2％ of the cases.Gender had no significant correlation with pathogen distribution.For the cases of complete spinal cord injury and tracheotomy,the ratio of mixed infection increased significantly (P ＜ 0.05).For the cases younger than 30 years,the pathogens were mainly gram-positive bacteria (P ＜ 0.05).Conclusions Main pathogens of pulmonary infection after ACSCI are gram-negative bacteria.The cases younger than 30 years are associated with higher risk of grampositive infection,while the cases with complete injury or tracheotomy are associated with higher risk of mixed infection.

A significant proportion of patients with chorea-acanthocytosis (ChAc) fail to respond to standard therapies. Recent evidence suggests that globus pallidus internus (GPi) deep brain stimulation (DBS) is a promising treatment option; however, reports are few and limited by sample sizes. We conducted a systematic literature review to evaluate the clinical outcome of GPi-DBS for ChAc. PubMed, Embase, and Cochrane Library databases were searched for relevant articles published before August 2021. The improvement of multiple motor and nonmotor symptoms was qualitatively presented. Improvements in the Unified Huntington’s Disease Rating Scale motor score (UHDRS-MS) were also analyzed during different follow-up periods. A multivariate linear regression analysis was conducted to identify potential predictors of clinical outcomes. Twenty articles, including 27 patients, were eligible. Ninety-six percent of patients with oromandibular dystonia reported significant improvement. GPi-DBS significantly improved the UHDRS-motor score at < 6 months (p < 0.001) and ≥ 6 months (p < 0.001). The UHDRS-motor score improvement rate was over 25% in 75% (15/20 cases) of patients at long-term follow-up (≥ 6 months). The multiple linear regression analysis showed that sex, age at onset, course of disease, and preoperative movement score had no linear relationship with motor improvement at long-term follow-up (p > 0.05). GPi-DBS is an effective and safe treatment in most patients with ChAc, but no reliable predictor of efficacy has been found. Oromandibular dystonia-dominant patients might be the best candidates for GPi-DBS.

Objective of this study was to evaluate the efficacy and safety of haploidentical or unrelated donor hematopoietic stem cell transplantation (HSCT) for patients with severe aplastic anemia (SAA). Twenty patients with SAA received allogeneic HSCT from haploidentical or unrelated donors (14 from haploidentical donors and 6 from unrelated donors) from November 2005 to May 2011. Conditioning regimen consisted of fludarabine (FLU), cyclophosphamide (Cy) and anti-thymocyte immunoglobulin (ATG). The patients were administrated with G-CSF-primed bone marrow and mobilized peripheral blood as grafts from haploidentical donor or only mobilized peripheral blood from the unrelated donor. The results showed that the median time of neutrophil and platelet engraftment were 14 (11 - 20) d and 17 (13 - 31) d respectively. All patients who achieved engraftment had complete hematologic recovery with complete donor chimerism, except for two patients who developed graft failure in 2 months after transplantation. Four cases developed acute grade IIGVHD. The chronic GVHD occurred in 7 of the 16 evaluable cases (6 limited, 1 extensive). 14 patients got disease-free survival with follow-up to January 2012. The disease-free survival rate was 68.9%. It is concluded that the haploidentical or unrelated donor hematopoietic stem cell transplantation may become a viable therapeutic option for severe aplastic anemia patients who lack suitable human leukocyte antigen-matched donors and fail immunosuppressive therapy.
