Objective: To observe the therapeutic efficacy of acupuncture combined with hyperbaric oxygenation for cervical spondylosis of nerve root type in acute phase.
Methods: One hundred cases with cervical spondylosis of nerve root type in acute phase were randomly divided into two groups, with 50 patients in each group. The patients in the treatment group were treated by acupuncture combined with hyperbaric oxygenation, and those in the control group only received the same acupuncture therapy as the treatment group. The therapeutic efficacy was evaluated after 2 courses of treatment.
Results: In the treatment group, 27cases were cured, 9 cases showed markedly effective, and 4 cases were invalid, and the recovery rate was 67.5%, the total effective rate was 90.0%; in the control group, 18 cases were cured, 17 cases showed markedly effective, 15 cases were invalid, and the recovery rate was 36.0%, the total effective rate was 70.0%. There were statistically significant differences between two groupsin the recovery rate and the total effective rate (bothP<0.05). The average cure time of the treatment group was (15.56±7.13) d, and that of the control group was (22.13±7.78) d, which also had significant difference between the two groups (P<0.05).
Conclusion: Acupuncture combined with hyperbaric oxygenationhas rapid and reliable effects for cervical spondylosis of nerve root type in acute phase.

Objective To investigate the clinical value of intraoperative iodine-125 seed implanttation in treating pancreatic carcinoma. Methods Seventy-five patients (fourty-one men, thirty-four women;median age 54 years) with pancreatic adenocarcinoma were enrolled into the study. Thirty-one patients (group A) were accepted tumor resection,eighteen patients(group B) were implanted radioactive iodine-125 seeds into the tumors by a combination of bypass surgery, twenty-six patients(group C) were treated by bypass surgery.Results Sixty-seven patients were followed up. The median survival time was 19, 12 and 7 months in group A,B,C respectively, among which the difference was significant (P ＜ 0.05). The response rate(CR+PR) was 50 % and the effective rate of pain relieving was 80% in the group B. The 97.4 % of accordance rate of seed number was demonstrated by CT film, but the accordance rate of seed space distribution was only 56 %.Conclusion At present, the active resection of the pancreatic carcinoma, including the superior mesenteric vein and the retropancreatic fusion fascia, is essential for a curative resection. The combination of Intraoperative iodine-125 brachytherapy and bypass surgery is safe and effective for pancreatic carcinoma.The seed space distribution completed by seed computer therapeutic plan needs further study.

BACKGROUND: Establishment of individual femoral model can describe the stereochemical structure of femoral accurately,which is conductive to measuring femoral anatomic forms. This model possesses unified standard, and removing the potential confounding factors, thus, it is more suitable for biomechanical test.OBJECTIVE: To explore a method for establishing an accurate individual femoral model.METHODS: A male, healthy, volunteer was selected from General Hospital of Tianjin Medical University, and the cross section of femur was successive scanned by 16 slice CT. In accordance with Dicom 3.0 standard, the CT image was reconstructed using Mimics software to establish the space model, and UG software was used to type on the workpiece, and cimatron software was used to sort, then set the coordinate system of computer numerical control machining, clamp and correct the workpiece to produce mold toolpath, so the mold was established. The femur model made by mould was compared with the femur by the method of point cloud.RESULTS AND CONCLUSION: An individual femur model was produced. The comparison results of point cloud showed that error was in allowing range. This is an advisable method to make a femoral model, which can achieve predetermined requirement.

BACKGROUND:At present,there are many established femoral finite element studies,but previous studies focused on femoral biomechanics of the outside are few.OBJECTIVE:To establish three-dimensional finite element model of structure of the proximal femur,and to analyze its biomechanics in normal standing position to provide reasonable evidence for clinical application.DESIGN,TIME AND SETTING:A three-dimensional finite element model analysis was performed in General Hospital of Tianjin Medical University from December 2008 to April 2009.PARTICIPANTS:One male volunteer aged 30 years was enrolled at General Hospital of Tianjin Medical University.Femur lesion or injury was excluded by means of X-ray.METHODS:The primitive femur CT data were adopted according to Dicom 3.0 standard in Mimics so as to obtain the primitive three-dimensional femur model which was established via threshold defining,region enlarging and morphological performing.The primitive model was remeshed and combined with ANSYS software to create a final finite-element model.The model obtained by using the Mimics was loaded with 200 N vertical loading to check out the difference of the stress distribution.MAIN OUTCOME MEASURES:Using 200 N as the external load in the vertical direction,the Vonmises stress distribution of the femur was detected.RESULTS:The applications of Mimics and Ansys software could create a finite element model of proximal femur.It was found that the correspondent relationship between stress and structure in proximal femur was verified.CONCLUSION:Mimics can build more three-dimensional finite element models in line with the proximal femoral mechanical structure and mechanical properties.The mechanical properties of the femur are more credible,and the results of the analysis support the clinical application of the guidance.

Objective To analyze the immunization coverage of 23-valent pneumococcal polysac-charide vaccine(PPV23)in a large population in Guangzhou and to evaluate its safety by analyzing the ad-verse events following immunization(AEFI)reported to the passive surveillance system. Methods Immu-nization data of PPV23 in Guangzhou from 2010 to 2015 were collected from Information Management System of Biological Products and the Information System of Immune Programming of Guangzhou. AEFI reported to the AEFI Information System during 2010 to 2015 was collected for safety evaluation. The collected data were analyzed by using descriptive methodology. Results A total of 621 059 doses of PPV23 were pre-scribed in Guangzhou from 2010 to 2015. Most of the recipients were children younger than 10 years old,ac-counting for 79. 44% . Only 9. 38% of the subjects received PPV23 were older than 60 years. A total of 243 AEFI cases were reported at a rate of 39. 13 cases per 100 000 doses,among which 199 cases(32. 04 / 105 ) showed minor vaccine reactions,25 cases(4. 03 / 105 )occurred adverse events,16 cases(2. 58 / 105 )de-veloped coupled diseases and 3 cases(0. 48 / 105 )were classified as psychogenic reactions. No rare adverse reactions were observed. Conclusion The majority of people immunized with PPV23s in Guangzhou were children,while the immunization coverage among the elderly was relatively low. PPV23 was safe for vaccina-tion as the reported AEFI cases were similar to that of other vaccines.
