Objective:To investigate the effects of rifaximin treatment outcomes on complications and 24-week survival rate in cirrhotic patients with refractory type ascites.Methods:A retrospective cohort study was conducted on 62 cases with refractory ascites, and were divided into rifaximin treatment group (42 cases) and control group (20 cases) according to the actual treatment conditions. Rifaximin treatment group patients were administered oral rifaximin-α 200 mg four times daily for 24 consecutive weeks, and the other treatments were basically the same in both groups. Fasting body weight, ascites, complications and survival rate between the two groups were observed. Measurement data of the two groups using t-test, Mann-Whitney U test, and repeated measures analysis of variance were compared. χ2 test or Fisher's exact test were used to compare the enumeration data between the two groups. Kaplan-meier survival analysis was used to compare the survival rates. Results:At 24-week of rifaximin treatment, patients average body weight was reduced by 3.2 kg and the average ascites depth was reduced by 4.5 cm with B-ultrasound measurement, while in the control group at 24-week, the average body weight was reduced by 1.1 kg and the average ascites depth was reduced by 2.1 cm with B-ultrasound measurement, and the differences between the two groups were statistically significant ( F=4.972, P=0.035; F=5.288, P=0.027). Hepatic encephalopathy incidence of grade II or above, hospitalization rates due to exacerbation of ascites, and spontaneous bacterial peritonitis were significantly lower in the rifaximin treatment group than those in the control group (2.4% vs. 20.0%, χ2=5.295, P=0.021; 11.9% vs. 50.0%, χ2=10.221, P=0.001; 7.1% vs. 25.0%, χ2=3.844, P=0.050). The 24-week survival rate was 83.3% in the rifaximin treatment group and 60.0% in the control group, P=0.039. Conclusion:Rifaximin treatment can significantly improve ascites symptoms, reduce the incidence of cirrhosis complications and improve the 24-week survival rate in cirrhotic patients with refractory type ascites.

Superchilling is an emerging technology for meat preservation; however, the temperature changes during the process have been commonly ignored. Thus, the effects of temperature fluctuations on meat quality during superchilling are yet to be evaluated. In our study, pork loins and salmon fillets were stored for several days (0, 8, 15, 23, and 30 d) under different temperature fluctuations based on -3.5 ℃ as the target temperature. The results showed that after 15 d of superchilling storage, the values of total volatile basic nitrogen, total viable count, and lipid oxidation were significantly (P<0.05) altered in the ±2.0 ℃ fluctuation group compared with the constant temperature group. On the contrary, there was no significant difference in these parameters between the ±1.0 ℃ fluctuation group and the constant temperature group after 30 d of storage. In addition, irregular temperature changes significantly accelerated the modulation of various indicators. In brief, temperature fluctuations and irregular temperature changes accelerated the destruction of muscle structural integrity, increased the water loss, gradually widened the water loss channels, and thereby reduced the edibility by accelerating the spoilage of meat.

Objective To study topological structure of a new type of three-dimensional (3D) printed height increasing insoles for leg length discrepancy (LLD) and its effect on biomechanics of lower limbs. Methods Topological structure for middle and rear part of the insole was optimized by solid isotropic microstructures with penalization (SIMP), the force was loaded and the boundary conditions were set according to force area of the insole, and the height increasing insole with thermoplastic polyurethanes (TPU) materials was printed by selected laser sintering (SLS). The insoles were used in 9 patients with LLD, visual analogue scale (VAS) and Maryland foot function scores were used to compare pain and foot function changes of patients before and after using the insole, and the 3D gait analysis system was used to compare spatiotemporal parameters and vertical ground reaction force (vGRF) of both lower limbs. Result sAfter the patient wore 3D printed insole, VAS scores decreased, Maryland foot function scores increased, vGRF of both lower limbs decreased, and the difference of cadence, stance phase and swing phase in both lower limbs decreased. Conclusions The 3D printed height increasing insole after topology optimization can improve coordination of lower limb movement, reduce ground impact, relieve pain and improve foot function, thus providing an effective personalized orthopedic plan for LLD treatment in clinic.
