With the increasing incidence of pelvic fractures, the concept of damage control was applied to the treatment of severe pelvic fractures, and the principle of phased treatment and indications were put for-ward. Meanwhile, the development of damage control surgery, which improves the survival rate and reduces the disability rate of patients, brings the treatments of pelvic fractures to a new stage.

[Objective] Posteroanterior weight-bearing radiographs,made with the knee in 45 degrees of flexion while the patient was standing on the homolateral foot,were compared with the weight-bearing anteroposterior radiographs with both knees in full extention,in order to find a more sensitive method to detect knee osteoarthritis.[Methods]Seventeen osteoarthritis knees were radiographed in the weight-bearing anteroposterior view with both knees in full extention and in the weight-bearing posteroanterior view with the knee in 45 degrees of flexion while standing on the homolateral foot.The minimum joint space width of all the radiograph were measured.The data were analysed statistically with SPSS 11.5.[Results]The mean minimum joint space width of the medial compart in extended knee view and standing on the homolateral foot were 4.65 mm?1.44 mm and 2.52 mm?1.69 mm,respectively(P

Objective To evaluate the correlation of interval from injury to surgery with outcome for central cervical spinal cord injury syndrome.Methods A retrospective analysis was done for 31 patients with central cervical spinal cord injury syndrome treated surgically between March 2007 and March 2011.According to the timing of surgical intervention,the patients were divided into early operative group (＜7 days from injury,n =14) and late operative group (≥7 days from injury,n =17).Japanese Orthopedic Association (JOA) score on admission,at postoperative half-year and at final follow-up were recorded and compared between the two groups.JOA recovery rate was determined and analyzed for correlation with operation time point.Results Mean follow-up was (16.1 ± 4.5) months (range,12-25 months).All patients had different degree of neurological recovery.JOA recovery rate in early operative group was apparently better than that in late operative group at final follow-up (P ＜ 0.01).JOA recovery rate at follow-up was negatively correlated with intervals between injury and surgery (r =-0.763,P ＜ 0.01).Conclusion For patients with central cervical spinal cord injury syndrome,time from injury to surgery is negatively correlated with outcome,indicating that early surgery may be associated with better outcomes.

Objective To discuss the clinical significance of percutaneous cervical diskectomy (PCD) in the management of radicular type cervical spondylosis. Methods A retrospective analysis was carried out on clinical records of 106 radicular type cervical spondylosis cases treated by PCD from July 1993 to June 2002. Results Follow-up observations for 6 months～8 years(mean 3.6 years) in 91 cases showed the outcomes were excellent in 36 cases, good in 40, and unchanged in 15, the rate of excellent-or-good results being 83.5%. Conclusions PCD has an excellent therapeutic effect for nerve-root symptoms resulted from cervical disc herniation, such as numbness and pain of the upper extremities or shoulders.

Objective To investigate the subthreshold depression for long-term survivors after breast cancer surgery and its effect on their quality of life (QOL). Methods The self-made general questionnaire, Centre for Epidemiological Studies Depression Scale (CES- D), Hamihon Rating Scale for Depression and Functional Assessment of Cancer Therapy- Breast were used to investigate the subthreshold depression and its effect on their QOL for 210 long-term survivors after breast cancer surgery. The difference in general conditions and score of QOL between the subthreshold depression and non-subthreshold depression groups was also compared. Results The subthreshold depression with incidence rate of 46.67%(98/210) was observed for the log-term survivors after breast cancer surgery in this study. The results indicated that the age (≤50) (OR=5.627, 2.662,P<0.01), marriage (unmarried, divorced or widowed) (OR=5.087, P<0.01), employment (unemployed, sick leave or retired) (OR=2.077,P<0.05) and low income (<3000 RMB/month) (OR=3.375,P<0.01) were the key factors that led to the occurrence of subthreshold depression. The score of QOL for the subthreshold depression group were lower than those of the non-subthreshold depression group (t=-6.653--2.926,P<0.01), and had a significantly negative correlation with score of depression and QOL (β=-0.362--0.132). Conclusions A high incidence rate of subthreshold depression for long-term survivors after breast cancer surgery was observed. The incidence rate of subthreshold depression increased for the patients with younger age, low income,unmarried or unemployment. Due to their low QOL, attentions should be paid to the early detection and early prevention for the long-term survivors with subthreshold depression after breast cancer surgery.

Objective To observe the management effect of pressure pain point and painful tubercle in occiput-neck part on tension-type headache (TTH). Methods 380 TTH patients were treated by palpating the central and both sides part from the external occipital protuberance to the spinous processes of neck; recording the total number and position of pressure pain points and painful tubercles; kneading, hitting and pressing all recorded pressure pain points and painful tubercles.Results After 1-6 times treatment, 283 were cured and 58 were effected. The efficiency ratio is 89.7%. Conclusion Muscle obstacle in occiput-neck part plays an important role in TTH. Massage therapy has a significant effect on pressure pain points and painful tubercle.

We applied bilingual teaching in internal medicine for students in our school from 2003 in order to cultivate medical students of high quality and to improve their ability in using professional foreign language.We analyzed our experiences from the aspects of teaching object,selection of teachers and teaching methods and summarized some problems during the process.We got the conclusions that only through strengthening bilingual teaching materials compiling,training young teachers and adopting diversified bilingual teaching means,can we achieve better bilingual teaching effect.

Objective To demonstrate the frequency changes in immune cells on secreting interleukin-10 (IL-10),interferon-? (IFN-?),tumor necrosis factor-? (TNF-?) and interleukin-4 (IL-4) under the stimulation of a mimic 7-amino acid peptide of HCV HVR1 (7P),and to explore the mechanism of such changes. Methods The peripheral blood mononuclear cells (PBMCs) were isolated from healthy people and co-cultured with 7P. Intracellular cytokine staining was performed using antibodies against IL-10,IFN-?,TNF-? and IL-4. The related cells were harvested on a FACSCalibur flow cytometer,and then analyzed with FACSCalibur software. Results Compared to the controls,the frequency of immune cells secreting IFN-? was significantly increased in both CD4+CD8-,CD4-CD8+ T cells and NK,NKT cells (P

Objective To compare the effect of Devine surgery with different fixed positions in the treatment of concealed penis.Methods According to the different fixed positions,45 patients with concealed penis in our hospital from January 2010 to February 2015 were divided into two groups:20 patients were treated with the method that fixing the scapus penis to dermis of the penis' root (group A);the other 25 patients were treated with the method that fixing the scapus penis to pectineal fascia (group B).The surgical success rate,the penile length,and the edema time after surgery between two groups were compared.Results There was no significant difference in surgical success rate and edema time between two groups (P ＞ 0.05).But the penile length of group B was longer than that of group A after surgery (P ＜ 0.05).Conclusion In the treatment of concealed penis with Devine surgery,comparing to the method which fixing scapus penis to dermis of penis'root,the method which fixing scapus penis to fascia pectinea is much better in penile length and penile appearance.
