Objective To compare the efficacy of intralesional glucocorticoid injection with a needle-free injector versus an ordinary injector for the treatment of keloid. Methods A total of 60 patients with keloid were enrolled and randomly divided into two groups by using a random number table to receive intralesional injection of compound betamethasone with a needle-free injector(n=31)or an ordinary injector(n=29). The injection was given at a dose of 0.2 ml/cm3 once every 3 weeks for 3 sessions. Parameters for therapeutic efficacy were assessed, adverse reactions were recorded, and clinical pictures were taken before and after each treatment. Statistical analysis was carried out by the Mann-Whitney U test and chi-square test with the SPSS 19.0 software. Results Compared with the ordinary injector group, the needle-free injector group showed significantly different injection time during the first and second treatment (U=299.000, 773.500, respectively, both P=0.000), as well as duration of pain after the first injection(U=730.000, P=0.003). After three sessions of treatment, there was a significant difference in the volume, height, hardness of keloid, scores for pain, itching and appearance, and number of injection points between the needle-free injector group and ordinary injector group (U=295.000, 336.500, 264.000, 464.000, 451.500, 308.000, 233.500, P=0.001, 0.007, 0.000, 0.041, 0.043, 0.003, 0.001, respectively). No significant differences were observed in the incidence of adverse reactions between the two groups(all P>0.05). Moreover, the interval for lesion recurrence was significantly shorter in the needle-free injector group(11.8 days, 95%CI:10.96-12.6 days)than in the ordinary injector group(21.2 days, 95%CI:13.96-28.45 days). Conclusion Compared with the ordinary injector, the needle-free injector shows better efficiency for the treatment of keloid with decreased difficulty in injection and improved compliance in patients.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4% at the 1-month follow-up and 96.4% at the 3-month follow-up in the treatment group. The total effective rate was 33.3% at the 1-month follow-up and 28.9% at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Objective To investigate the effects of preventive chemotherapy for hepatocellular carcinoma (HCC) exceeding Milan criteria after liver transplantation. Methods The clinical data of 243 patients who had undergone orthotopic liver transplantation for HCC exceeding Milan criteria from April 2001 to July 2007 were retrospectively analyzed. Of all patients, 162 received preventive chemotherapy after transplantation. Results The 1- and 3-year survival rates and disease-free survival rates were not statistically different between patients who had received chemotherapy (78.5%, 63.7% ; 76.8%, 52.5% ) and those without chemotherapy (56.6%, 39.1%; 69.3%, 64.7% ) (X2 = 3.084, 0.444, P > 0.05). Cox regression analysis demonstrated that postoperative chemotherapy was not an independent factor affecting the survival rates of HCC patients without vascular invasion, but an independent factor affecting the survival rates of HCC patients with vascular invasion. Conclusions Early preventive chemotherapy could obviously increase the survival rate and delay the tumor recurrence of patients with HCC exceeding Milan criteria, especially for HCC patients with vascular invasion.
