Objective To determine the relationship between zinc and nutritional status or immunity in patients with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis (CAPD). Methods Forty-five stable CAPD patients undergoing peritoneal dialysis were enrolled in this study. The dietary zinc intake and serum zinc levels were investigated, and the results were compared with the gender- and age-matched healthy populations (n = 45). The relationship between dietary zinc intake and serum zinc levels and subjective global assessment (SGA) score, blood cell counts, serum albumin (ALB), prealbumin (PA), C-reactive protein (CRP),and lymphocyte subsets were analyzed. Results The percentages of inadequate dietary zinc intake (P= 0. 007)and low blood zinc (P = 0. 036) were significantly higher in CAPD patients than in healthy group. CD8 levels were significantly lower (P = 0. 000) while CD4/CD8 ratio was significantly higher (P = 0. 033) in CAPD patients than in healthy group. In CAPD patients, correlation analysis showed that dietary zinc intake was significantly correlated with serum prealbumin levels (r = 0. 577, P = 0. 000), but was negatively correlated with SGA score (r = - 0.354,P = 0. 015) and CRP (r = - 0.354, P = 0. 015); however, it was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Serum zinc level was significantly positively correlated with hemoglobin (r= 0. 411, P=0.005), hematocrit (r=0.345, P=0.023), WBC (r=0.318, P=0.035), SGA score (r=0.417, P=0. 005), and CRP (r=0.342, P = 0. 027), but was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Conclusions Zinc deficiency is common among patients with CAPD. Adequate dietary zinc intake can facilitate protein synthesis and improve the overall nutritional status. High serum zinc concentrations are beneficial for the synthesis of hemoglobin and the improvement of anemia.

Phytantriol (PT), ethanol (ET) and water were used to prepare in situ cubic liquid crystal (ISV2). The pseudo-ternary phase diagram of PT-ET-water was constructed and isotropic solution formulations were chosen for further optimization. The physicochemical properties of isotropic solution formulations were evaluated to optimize the composition of ISV2. In situ hexagonal liquid crystals (ISH2) were prepared based on the composition of ISV2 with the addition of vitamin E acetate (VitEA) and the amount of VitEA was optimized by in vitro release behavior. The phase structures of liquid crystalline gels formed by ISV2 and ISH2 in excess water were confirmed by crossed polarized light microscopy and small angle X-ray scattering, respectively. Rheological properties of ISV2 and ISH2 were studied by a DHR-2 rheometer. In vitro drug release studies were conducted by using a dialysis membrane diffusion method. Pharmacokinetics was investigated by determination of sinomenine hydrochloride (SMH) concentration in synovial membrane after intra-articular injection of SMH-loaded ISH2 in adjuvant-induced arthritis rats. The optimal ISV2 (PT/ET/water, 64 : 16 : 20, w/w/w) loaded with 6 mg x g(-1) of SMH showed a suitable pH, injectable and formed a cubic liquid crystalline gel in situ with minimum water absorption in the shortest time. The optimal ISV2 was able to sustain the drug release for 144 h. The optimal ISH2 system was prepared by addition of 5% VitEA into PT in the optimal ISV2 system. This ISH2 (PT/VitEA/ET/water, 60.8 : 3.2 : 16 : 20, w/w/w/w) was an injectable isotropic solution with suitable pH. The new ISH2 was able to sustain the drug release for more than 240 h. Local pharmacokinetics study indicated that the retention time and AUC(0-∞) of ISH2 group were increased significantly compared with that of SMH solution group and the AUC(0-∞) of ISH2 group was 6.01 times higher than that of SMH solution group. The developed ISH2 was suitable for intra-articular injection that may apply to patients in the treatment of rheumatoid arthritis.
