Objective To summarize complications and early clinical effect of less invasive stabilization system and the femoral condylar support plates in treatment of AO type C distal femoral fractures. Methods We reviewed 46 patients who had internal fixation of AO type C distal femoral fractures. Of all 46 patients, 25 were with less invasive stabilization sys-tem and 21 were with femoral condylar support plates fixation. Comparative analysis was performed using intraoperative in-dex, postoperative complications and the Evanich score at follow-up. Results All 46 patients were followed up with a mean time of 19.6 months after surgery. The difference in incision length, blood loss, fracture healing time was significant between the 2 groups(P＜0.05)but not in the duration of operations and hospital stays(P>0.05). The statistical signifi-cance was also found in the total incidence of postoperative complications and the Evanich score at the last follow-up(P＜0.05). Conclusion Patients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time, less postoperative complications and better functional recovery compared with femoral condylar sup-port plates. Less invasive stabilization system had became an ideal internal fixation in treatment of AO type C distal femoral fractures.

Objective To explore the reason for remedy radical operation after endoscopic submucosal dissection (ESD) for early gastric cancer.Methods The clinical data of 26 early gastric cancer cases who received remedy radical gastrectomy after ESD between January 2012 to March 2015 in Nanjing Drum Tower Hospital were analyzed retrospectively.Results All cases were followed up and mid follow-up was 25 months.There was no death nor tumor reccurence cases during the follow-up.Three cases suffered from complications in radical surgery for gastric cancer including afferent jejunal loop obstruction,adhesive intestinal obstruction,stomach paralysis respectively,all were cured by conservative therapy.Postoperative pathology found lymph node metastasis in 3 cases.Conclusions En bloc resection and negative resection margin,as well as free lymphatic metastasis are two important factors determing the survival of early gastric cancer patients undergoing ESD treatment.

OBJECTIVE: To explore the laws of traditional Chinese medicine (TCM) syndromes in unstable angina, and to establish the preliminary diagnostic criteria for TCM syndromes. METHODS: Multi-center prospective research on TCM syndromes in 815 cases of unstable angina was done with the nonlinear dimension reduction by factor analysis. RESULTS: There were five extracted factors in factor analysis: F1, F2, F3, F4 and F5. F1 was yin deficiency of heart and kidney, F2 was deficiency of both heart and spleen, F3 was intermingled phlegm and blood stasis, F4 was qi deficiency and blood stasis, and F5 was yang deficiency and coagulated cold. Qi deficiency and blood stasis (F4) syndrome accounted for the maximum proportion. The diagnostic criteria for TCM syndromes were preliminarily and respectively established. CONCLUSION: Qi deficiency and blood stasis is the key factor of pathogenesis. The factor analysis can help us classify traditional Chinese medicine syndromes and establish the preliminary diagnostic criteria.
