  • Efficacy of Shenlingcao Oral Liquid for Asymptomatic HIV-infected People: A Before-and-after Self-control Study

    ObjectiveTo observe the effects of Shenlingcao oral liquid on HIV-RNA load, CD4+ T cells of HIV carriers. MethodsWe included asymptomatic HIV-infection people from February to April 2012, gave them Shenlingcao oral liquid for oral intake (1 bottle/d, 200 mL/bottle) during 6 months, and observed the changes of HIV-RNA load and CD4+ T cell at different time points (before intake, 2 months, 4 months, and 6 months). ResultsA total of 25 cases were included. The results showed that a tendency existed that CD4+ T cells counts gradually increased along with time; HIV-RNA load did not change regularly; and the total effective rate was steady; and the cases in steady status tended to increase. ConclusionShenlingcao oral liquid is beneficial to the improvement of the immunity of asymptomatic HIV-infected people. Because of limited sample size and study design, the above conclusion should be verified by further conducting large-scale high quality randomized controlled trials.

  • A comparative study on effectiveness of patellar resurfacing against non-resurfacing in total knee arthroplasty

    ObjectiveTo investigate the effectiveness of total knee arthroplasty (TKA) with or without patellar resurfacing.MethodsBetween March 2013 and August 2015, 30 patients (60 knees) with osteoarthritis who met the inclusion criteria were recruited in the study. Of 30 cases, 24 were male and 6 were female with an average age of 57.2 years (range, 37-65 years). The body mass index ranged from 19.5 to 40.3 kg/m2 (mean, 28.2 kg/m2). According to Kellgren-Lawrence grading, there were 8 cases at grand Ⅲ and 22 cases at grand Ⅳ. All patients underwent primary bilateral TKA. The patellar resurfacing was done at the unilateral knee randomly (resurfacing side); the opposite treatment was done at the other side (non-resurfacing side). The indexes of 2 groups were recorded and compared, including the intraoperative blood loss, operation time, knee society score (KSS), " Forgotten Joint” scale (FJS), anterior knee pain, anterior patellar spirant, knee constraint feeling, anterior patellar clunk, muscle power of knee extension, and ability of up and down stairs, weight-bearing flexion, squatting down, cross-legged, knee down, knee extension, and patient satisfaction. Radiographic examination was used to analyze the prosthesis position.ResultsThe operation time were (126±14) minutes and (112±11) minutes in resurfacing side and non-resurfacing side, respectively, showing significant difference between two sides (t=5.103, P=0.030); and there was no significant difference in intraoperative blood loss between two sides (t=3.431, P=0.800). All patients were followed up 2-4 years (mean, 2.6 years). There was no significant difference (P>0.05) between two sides in KSS clinical and functional scores at preoperation and 6 weeks, 6 months, and 2 years after operation; in visual analogue scale (VAS) score of anterior knee pain at preoperation and 6 weeks after operation; in incidences of anterior patellar spirant, knee constraint feeling, anterior patellar clunk, and muscle power of knee extension at 6 weeks, 6 months, and 2 years after operation; in incidences of disability of up and down stairs, weight-bearing flexion, squatting down, cross-legged, knee down, and knee extension at 6 weeks, 6 months, and 2 years after operation; in ratio of FJS score at 2 years after operation. The VAS scores at 6 months and 2 years after operation in resurfacing group were significantly lower than those in non-resurfacing group (Z=–1.997,P=0.046; Z=–2.197,P=0.028). Patient satisfaction of resurfacing side was superior to the non-resurfacing side at 6 weeks after operation (χ2=4.271, P=0.039). Radiographic examination showed no prosthesis loosing occurred.ConclusionThe effectiveness of TKA with patellar resurfacing is better than that with non-resurfacing in patients satisfaction.
