OBJECTIVETo analyze rationality of internal fixation with original fixation in the second operation for femoral nonunion.

METHODSA retrospective study was conducted to analyze the clinical data of 19 femoral nonunion patients treated by internal fixation with original fixation in the second operation since January 2009 to July 2014, including 14 males and 5 females with an average age of (43.63 ± 3.95) years old ranging from 18 and 75 years old. The original fixations involved plate fixation in 11 cases and interlocking intramedullary nail in 8 cases (including 3 cases of retrograde interlocking intramedullary nails). There were 13 cases of atrophic nonunion and 6 cases of hypertrophic nonunion in pathological classification. After second operation, the fracture healing time, Harris hip score and range of motion of the knee joint was recorded and compared with preoperative.

RESULTSAfter the second operatioin, all patients were followed up for 6 to 30 months with an average of (18.67 ± 7.59) months. All patients got fracture healing, and the fracture radiological healing time was from 7 to 29 months with an average of (15.78 ± 4.97) months. Harris hip scores were improved from preoperative 62.37 ± 19.48 to postoperative 87.42 ± 8.86. The range of motion of the knee joint was improved from preoperative (52.16 ± 20.10)° to postoperative (96.32 ± 22.10)°.

CONCLUSIONIt has a better clinical healing rate for using original fixation to treat femoral nonunions, and theoretically speaking it was rationality.

Objective To investigate the clinical efficacy of combination of umbilical compress therapy with Xiaotan Lishui Gel and intraperitoneal chemotherapy with cisplatin in patients with gastric cancer ascites. Methods A total of 78 patients were included and divided randomly into treatment group (39 patients) and control group (38 patients). Patients of both groups received intraperitoneal chemotherapy with cisplatin, and the treatment group received additionally umbilical compress therapy of Xiaotan Lishui Gel. Two weeks were regarded as a course of treatment. All patients were followed up for 180 days. The total effective rate, puncture-free survival, interval time of puncture, median survival time, life quality, improvement of symptoms and safety of the two groups were observed. Results Finally 73 patients completed the observation. The total effective rate was 56.76%(21/37) in the treatment group and 33.33%(12/36) in the control group, with statistical significance (P=0.044). The puncture-free survival and interval time of puncture were 59 d and 62 d, respectively, and 49 d and 54 d in the control group, respectively (P<0.05). There was no difference in median survival time between the two groups. Karnofsky performance status in the treatment group was significantly higher than the control group (P=0.012), and decreased mobility, abdominal pain, abdominal distension, early satiety and urinary frequency in the treatment group were better improved than the control group (P<0.05). Conclusion Combination of umbilical compress therapy with Xiaotan Lishui Gel and intraperitoneal chemotherapy with cisplatin can postpone the ascites increasing speed of patients with gastric cancer ascites, and improve patients’ life quality.
