Objective To investigate efficacy and effect on liver function of the experimental therapy with balloon catheter to block the main artery temporarily and then pressurize chemoembolization to treat hypovascular liver cancer. Methods Eighty patients with hypovascular liver cancer requiring interventional therapy were randomly divided into two groups.The experimental group was treated with the new therapy and the control group was treated with traditional therapy. The lipiodol-filling status and maximum diameter of the tumor was analyzed for a midterm outcome,and the change of AFP and liver function were evaluated.Mann-Whitney test was used for data between two groups,Friedman test was used for data of each group,and Spearman nonparameter relevant analysis was used for efficacy indexes.Results ( 1 ) All Patients have confirmed diagnosis of hypocvascular liver cancer and got balanced baseline. ( 2 ) Lipiodol-filling status:the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 1,3,12 months (Z =-2.135,- 2.939,- 2.686 ; P =0.034,0.004,0.007 ),but no statistically significant difference in 6 month ( Z =- 1.170,P =0.242 ).The status of lipiodol-filling of experimental group ( x2 =2.593,P =0.459 ) was more stable than control group ( x2 =10.886,P =0.012).(3) Maximum diameter of the tumor:the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 3,12 months ( Z =- 2.734,- 2.733 ; P =0.006,0.006),but no statistically significant difference in 1,6 month ( Z =- 1.692,- 1.895 ;P =0.091,0.058). But neither of two groups showed statistically significant difference in change of maximum diameter of the tumor ( x2 =5.500,P =0.139 ; x2 =6.509,P =0.089 ).Relation between lipiodol-filling and maximum diameter showed positive correlation in 3 month ( r =0.257,P =0.035 ). (4) Stratified analysis was used for data of AFP according to AFP value before therapy,and two groups showed no statistically significant difference for patients belonging to 20-1000 μg/L by Pearson Chi-square test. (5)Two groups showed no statistically significant difference for data of liver function before therapy and in 1,3,6months ( Z =- 1.073,- 1.314,-0.518,-0.549;P=0.308,0.189,0.604,0.583).Conclusions According to the midterm result of this experiment,the experimental therapy increased lipiodol-filling and decreased maximum diameter of the tumor significantly in 3 and 12 months correspondingly,but no significant difference was observed in AFP and liver function between groups yet. So the long-term efficacy and its influence to lung metastasis and survival rate need further research.

Objective To observe the effect of Chinese herbal fumigation combined with CPM promote the function recovery after Postoperative Patellar Fracture. Methods Eighty patients with patellar fracture were randomly divided into treatment group (40 cases) and control group (40 cases). The control group was treated with CPM. The treatment group was treated with Chinese Herbal Fumigation and CPM. After 8th weeks, the clinical curative effect, knee range of motion and KSS knee score were observed and compared. Results The effect rate of the treatment group was 87.5% (35/40), and the control group was 65.0% (26/40). The difference was statistically significant (χ2=5.591, P<0.01). After treatment, the range of motion of knee joint (138.38°± 7.82°vs. 0.29°± 7.83°, t=10.338), KSS knee function score (88.38 ± 9.52 vs. 3.46 ± 9.36, t=2.330) of the treatment group were higher than those in the control group (P<0.01 or P<0.05). Conclusions The Chinese medicine fumigation combined with CPM functional exercise could accelerate the recovery of knee function and reduce the complications of fracture after patellar fracture.

Objective Evaluation of the effect of manual reduction with small external fixation on the treatment of elderly Barton fractures.Methods A total of 244 elderly patients with Barton fractures were divided into conservative group (n=126) and operation group (n=118) according to random number table. The conservative group was treated by with manual reduction with small external fixation, and the operation group was treated with open reduction and internal fixation. The complications of the patients, the time of fracture healing, hospitalization time and treatment cost were recorded.The wrist function was evaluated by PRWE wrist score system and Wrightington wrist function score system.The clinical efficacy was evaluated by Gartland-Werley Colles fracture evaluation method.Results The excellent and good effect rate was 91.3% (115/126) in the conservative group and 97.5% (115/118) in the operation group. There was no significant difference between the two groups(χ2=0.857,P=0.354). One year, 6 months, 3 months and 6 weeks after treatment, in the conservative group, the PRWE score (10.4 ± 7.9, 19.1 ± 8.0, 40.5 ± 7.8, 55.7 ± 8.1vs. 80.8 ± 8.2,F=113.665), wrightington score (8.2 ± 3.7, 13.2 ± 4.0, 21.4 ± 3.9, 26.3 ± 4.2vs. 30.1 ± 4.2,F=121.348) were significantly lower than those before treatment (P<0.01). And in the operation group, the PRWE score (10.2 ± 7.8, 15.0 ± 8.0, 26.5 ± 8.0, 44.7 ± 8.2vs. 79.6 ± 8.6,F=81.411), Wrightington score (8.1 ± 3.8, 12.1 ± 4.0, 16.5 ± 4.0, 20.6 ± 4.3vs. 29.8 ± 4.6,F=69.113) were significantly lower than those before treatment (P<0.01). But there was no significant difference in PRWE score and Wrightington scores between the two groups after treatment (t=0.149, 0.104,P=0.881, 0.917, respectively). In the conservative group, the hospitalization time (5.28 ± 2.10 dvs. 12.8 ± 2.21d,t=25.260) was significantly shorter than that of the control group (P<0.01), and the treatment cost (3.26 ± 0.93 thousandvs. 28.66 ± 1.04 thousand,t=200.369) was significantly lower than that in the control group (P<0.01). The overall incidence of complication was 8.7% (11/126) in the conservative group and 17.8% in the surgery group (21/118). There was significant difference between the two groups(χ2=4.396,P=0.036).Conclusions The manual reduction with small splint external fixation was simple, low cost, small trauma, short hospitalization time, and less complications.

Objective To determine the half-effective target effect-site concentration (Ce) (EC50) of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol in patients undergoing transureteroscopic holmium laser lithotripsy. Methods Fifty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr, BMI ＜ 30 kg/m2 , undergoing transureteroscopic holmium laser lithotripsy were randomly divided into 5 groups according to the different C es of sufentanil ( n = 10 each): group S1 (Ce 0.21 ng/ml), group S2(Ce 0.14 ng/ml), group S3(Ce 0.09 ng/ml), group S4(Ce 0.06 ng/ml), group S5(Ce 0.04 ng/ml). TCI of propofol with target plasma concentration set at 2.5-3.0 μg/ml was given. Sufentanil with the corresponding Ce was infused in each group. The ureteroscopes were inserted as soon as the patients lost consciousness and the effect-site concentration of sunfentanil was achieved. The response was defined as positive when body movement occurred within 1 min after insertion of ureteroscopes. The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol and 95% confidence interval (CI) were calculated. Results The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol was 0.084 ng/ml and 95% CI was 0.066-0.107 ng/ml. Conclusion The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes was 0.084 ng/ml when combined with propofol.

Objective: To discuss the effect and safety of continuous pumping for home enteral nutrition after esophagectomy. Methods: The current study retrospectively analyzed the esophageal cancer patients who underwent transthoracic esophagectomy between January 2017 and November 2017 at First Department of Thoracic Surgery, Peking University Cancer Hospital and Institute. There were totally 108 cases, including 88 males and 20 females, with an average age of 62 years. The patients were divided into pump feeding group (n=56) and traditional tube feeding group (n=52). The postoperative short-term safety, weight maintenance, enteral nutrition tolerance and nutritional support complete rate of the 2 groups were compared by χ² test, Fisher exact test and t test, respectively. Results: Compared with traditional tube feeding group, the patient safety in pumping feeding group was significantly better, with complications within 2 months after discharge were 11/52 and 4/56 respectively (χ²=2.393, P=0.035); the weight maintenance was significantly better, the weight loss within 4 weeks after discharge were 3.90 kg and 0.13 kg, respectively (t=7.720, P=0.000); the general enteral complications were significantly lower (26/52 vs. 5/56, χ²=22.225, P=0.000), the nutritional support complete rate was significantly higher (23/52 vs. 55/56, χ²=39.167, P=0.000). Conclusions Continuous pump feeding enteral nutrition support after discharge postoperatively could help improve patient safety after discharge, which is better for weight maintenance of the patients. Pump feeding could also enhance tolerability of tube feeding and ensure the effective accomplishment of nutritional support.
