Objective To explore the effect of infrared ray treatment on improving fat granules survival rate and reducing postoperative complications in autologous fat transplantation. Methods The patients who received autologous fat transplantation were divided into infrared ray group and control group.Each group was further divided into breast group and face group. These cases in infrared ray group were radiated for 30 minutes with infrared ray 24 hours later after surgery, once a day for sequential 5 days.No treatment was given to the control group. The survival status and complication were observed and statistically analyzed. Results Infrared ray treatment could increase fat granules survival rate after autologous fat transplantation, but no significant effect was acheived on reducing complications. Conclusion Infrared ray treatment is an effective way to enhance the survival rate of fat granules.

Heart rate is the most common index to directly monitor the level of physical stress by comparing the subject's heart rate with an appropriate "target heart rate" during exercise. However, heart rate only reveals the cardiac rhythm of the complex cardiovascular changes that take place during exercise. It is essential to get the dynamic response of the heart to exercise with various indices instead of only one single measurement. Based on the rest-workload alternating pattern, this paper screens the sensitive indices of exercise load from electrocardiogram (ECG) rhythm and waveform, including 4 time domain indices and 4 frequency domain indices of heart rate variability (HRV), 3 indices of waveform similarity and 2 indices of high frequency noise. In conclusion, RR interval (heart rate) is a reliable index for the realtime monitoring of exercise intensity, which has strong linear correlation with load intensity. The ECG waveform similarity and HRV indices are useful for the evaluation of exercise load.

ObjectiveTo investigate the clinical effect of Dahuang Zhechong capsules combined with entecavir in the treatment of chronic hepatitis B (CHB) patients with liver fibrosis. MethodsA total of 100 CHB patients with liver fibrosis who visited or were hospitalized in Shenzhen Hospital of Peking University from October 2014 to January 2016 were enrolled and randomly divided into Western medicine group and combined treatment group, with 50 patients in each group. The patients in the Western medicine group were given entecavir, and those in the combined treatment group were given Dahuang Zhechong capsules in addition to entecavir. The course of the treatment was 48 weeks. The changes in liver function, HBV DNA load, four serum parameters of liver fibrosis, liver stiffness, and aspartate aminotransferase-to-platelet ratio index (APRI)/FibroIndex were observed in both groups. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. ResultsBoth groups showed significant reductions in serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and HBV DNA load after 48 weeks of treatment (all P＜0.05). After treatment, the four serum parameters of liver fibrosis all returned to normal after treatment, and the serum levels of hyaluronic acid, type Ⅲ precollagen, and type IV collagen showed significant differences between the two groups (all P＜005), and the portal vein diameter, thickness of the spleen, liver stiffness and APRI/FibroIndex also showed significant differences between the two groups (both P＜0.05). The combined treatment group had a significantly higher overall response rate than the Western medicine group (920% vs 720%, χ2=6.775, P=0009). ConclusionDahuang Zhechong capsules combined with entecavir have a better effect in the treatment of CHB patients with liver fibrosis compared with entecavir alone.
