Objective: Our purpose was to explore the change regularity of β-glucuronidase (β-G) in body of patients with Non-Hodgkin malignant lymphoma. Methods: β-G was examined synchronously both in the serum and in the tumor tissue of 13 cases patient with Non-Hodgkin malignant lymphoma by using the method of enzymlinked immunsorbent assay (ELISA) and immunohistochemistry separately. Among them, 3 cases were studied by using the immuno electron microscopic technique. Results: β-G was highly expressed both in the serum and tumorous tissue in patients with non-Hodgkin malignant lymphoma and there was obviously difference as compared with the control group (P<0.01). Conclusion: The combined detection with functional and morphological methods to β-G, it may be assistant target to early discovery and early diagnosis of Non-Hodskin malignant lymphoma.

Objective:To understand cognition and satisfaction degree of mental health service among residents in Weifang,and provide reference for further development of mental health work.Methods:6174 residents were selected with random sampling method and a cognition survey was conducted using a self-designed questionnaire.Among them,553 residents were selected to investigate their satisfaction with mental health service.Results:The residents have unscientific cognition on mental health service,and they did not understand the delivery of community mental health services.Residents who have received mental health service were more satisfied with informed consent and patient privacy protection,and had low satisfaction with the clinic environment and the charge of inspection items.Conclusions:To improve residents' cognition and satisfaction of mental health service,we should further perfect the professional mental health institutions and personnel recruiting,and forcefully carry out mental health education.

Objective:This article is to study the quality of life and the situation of social support for the elderly in Weifang while analyzing the correlation between them.Methods:This study was undertaken among elderly aged over 60 followning the European five D health scale and Social Support Rating Scale.The results were analyzed statistically.Results:On the living quality of elderly in Weifang,the EQ-SD index was (0.78 ±0.12) and the EQ -VAS index was (76.42 ± 14.67).The result from each scale shows a tremendous health issue among the elderly in Weifang.On the other hand,the situation of social support for the elderly in Weifang appeared optimistic.Still,this situation can be improved in practical supports.Also,there was significant negative correlation between EQ-5D and SSRS (r =0.260,P ＜ 0.05).Results of multiple linear regression show that the subjective support and objective support may enter the regression equation.Conclusion:To conclude,the city of Weifang awaits improvements in aged care and social support for the elderly.Only by this chance the quahty of life of the elderly may be improved.

Objective:To evaluate the long-term outcomes of posterior release, reduction, fixation, and fusion for irreducible atlantoaxial dislocation (AAD).Methods:Between January 2005 and June 2016, a total of 31 patients with irreducible AAD who had received posterior approach surgery were included. Among them, there were 13 males and 18 females, the average age was 39.1±13.5 years (range 9-72 years). The clinical data of the eligible individuals were collected and analyzed. Neck disability index (NDI) and Japanese Orthopaedic Association (JOA) scores were recorded to evaluate the recovery of neck and neurological functions. The atlantodental interval (ADI), clivus-canal angle (CCA), and cervico-medullary angle (CMA) were measured to evaluate the reduction of AAD. C 0-C 2 angle and C 2-C 7 angle were measured to evaluate the recovery of cervical alignment. For individuals with basilar invagination, the distances from the tip of odontoid process to Chamberlain line and Wackenheim line were measured to assess the reduction in the vertical direction. The duration of bony fusion and complications were also analyzed. Results:The mean follow-up period was 82.7±26.4 months (range 61-170 months). In terms of functional scores, the NDI dropped from 43.41%±11.60% before surgery to 12.19%±6.97% at the six months follow-up, and 9.45%±7.51% at the last follow-up ( F=89.56, P<0.001). The JOA increased from 9.48±2.41 points before surgery to 14.71±1.42 points at the six months follow-up, and 14.97±1.47 points at the last follow-up ( F=52.89, P<0.001). Regarding the horizontal and vertical dislocations, the ADI decreased from 9.16±2.32 mm before surgery to 1.39±1.04 mm at the six months follow-up, and 1.29±1.08 mm at the last follow-up ( F=189.61, P<0.001). The distance from the tip of odontoid process to Chamberlain line decreased from 11.15±4.35 mm before surgery to 2.03±2.83 mm at the six months follow-up, and 2.15±3.02 mm at the last follow-up ( F=37.58, P<0.001). The distance from the tip of odontoid process to Wackenheim line reduced from 6.81±2.57 mm before surgery to -2.23±1.58 mm at the six months follow-up, and -2.27±1.58 mm at the last follow-up ( F=122.16, P<0.001). For the amelioration of the compression on medulla and spinal cord, the CCA increased from 113.68°±12.67° before surgery to 143.39°±7.38° at the six months follow-up, and 142.39°±7.13° at the last follow-up ( F=67.13, P<0.001). The CMA increased from 115.71°±13.69° before operation to 145.58°±10.78° at the last follow-up ( F=41.44, P<0.001). Regarding the curvature of the cervical spine, the C 0-C 2 angle recovered from 1.94°±15.82° before surgery to 14.84°±6.45° at the last follow-up ( F=11.97, P<0.001), and the C 2-C 7 angle ameliorated from 27.26°±8.49° before operation to 19.26°±5.44° at the last follow-up ( F=11.13, P<0.001). Bony fusion was achieved in all cases, the fusion time was 9.71±2.55 months (range 5-15 months). A total of five complications occurred in the cases (two cerebrospinal fluid leakages, one deep infection, one transient neurologic deficit, and one dysphagia). They were all cured with corresponding treatments. In the last follow-up, none of the cases developed failure of internal fixation or re-dislocation. Conclusion:Posterior approach release, reduction, fixation and fusion technique is a safe and efficient surgical strategy with favorable long-term follow-up outcomes for irreducible AAD.
