ABSTRACT
<p><b>OBJECTIVES</b>To investigate whether three strains of probiotics, L. acidophilus, L. rhamnosus, and L. sporogenes, had signifificant inhibitive effects on Helicobacter pylori (H. pylori).</p><p><b>METHODS</b>This is a 4-week, randomly assigned, parallel-group, doubled-blind, and placebo-controlled study. Fifty patients with a positive H. pylori infection urea breath test (△UBT) result > 10% and without ulcer symptoms were randomized into a treatment group and a placebo group by a computer generated allocation sheet with 1:1. These subjects took one capsule of probiotics or placebo twice daily. The primary measurement was the change in △UBT values.</p><p><b>RESULTS</b>The △UBT values during the 4-week treatment period and the 2-week follow-up period were not signifificantly different between the treatment group and the placebo group, indicating that the inhibitive effects on H. pylori were comparable between both groups. The monocyte count (%) was 5.77±1.11 in the treatment group versus 5.09±1.12 in the placebo group (P=0.044), and the basophile count was 0.55±0.32 in the treatment group versus 0.36±0.23 in the placebo group (P=0.024) at week 2 of the treatment period, both of which reached statistical signifificance. The monocyte count was 5.75±1.26 in the treatment group and 4.72±0.99 in the placebo group at the end of the follow-up period (P=0.003).</p><p><b>CONCLUSION</b>There was no signifificant inhibitive effects of the three probiotic strains (L. acidophilus, L. rhamnosus, and L. sporogenes) on H. pylori. Probiotics can not play the same role as antibiotics in the eradication of H. pylori, the role of probiotics is likely to be important as adjuvant to the triple or quadruple therapy for H. pylori, especially in resistance cases.</p>

<p><b>OBJECTIVE</b>To observe the effect of combining red yeast rice and Lactobacillus casei (L. casei) in lowering cholesterol in patients with primary hyperlipidemia, the later has also been shown to remove cholesterol in in vitro studies.</p><p><b>METHODS</b>A double-blind clinical trial was conducted to evaluate the cholesterol-lowering effect of the combination of red yeast rice and L. casei. Sixty patients with primary hyperlipidemia were recruited and randomized equally to either the treatment group (red yeast rice + L. casei) or the control group (red yeast rice + placebo). One red yeast rice capsule and two L. casei capsules were taken twice a day. The treatment lasted for 8 weeks, with an extended follow-up period of 4 weeks. The primary endpoint was a difference of serum low-density lipoprotein cholesterol (LDL-C) level at week 8.</p><p><b>RESULTS</b>At week 8, the LDL-C serum level in both groups was lower than that at baseline, with a decrease of 33.85±26.66 mg/dL in the treatment group and 38.11±30.90 mg/dL in the control group; however, there was no statistical difference between the two groups (P>0.05). The total cholesterol was also lower than the baseline in both groups, yet without a statistical difference between the two groups. The only statistically signifificant difference between the two groups was the average diastolic pressure at week 12, which dropped by 2.67 mm Hg in the treatment group and increased by 4.43 mm Hg in the placebo group (P<0.05). The antihypertensive activity may be associated with L. casei. Red yeast rice can signifificantly reduce LDL-C, total cholesterol and triglyceride.</p><p><b>CONCLUSION</b>The combination of red yeast rice and L. casei did not have an additional effect on lipid profifiles.</p>
ABSTRACT
<p><b>OBJECTIVE</b>Animal studies have demonstrated a lipid-modulating effect of yun-cai tea. However, little is known about the lipid-lowering effect in humans.The aim of this study was to evaluate the lipid lowering effects and safety of yun-cai tea in patients with elevated lipid levels in a human clinical trial.</p><p><b>METHODS</b>This was a 12-week, randomly assigned, parallel-group, double-blind, and placebo-controlled pilot clinical study. Sixty primary hyperlipidemia patients were included and randomly assigned to the yun-cai tea group (30 patients) and the placebo group (30 patients), for 8 weeks of treatment and 4 weeks of follow-up. The primary endpoint was changes in plasma low-density lipoprotein-cholesterol (LDL-C) at 8 weeks. The secondary endpoints included total cholesterol (TC) and triglycerides (TG).</p><p><b>RESULTS</b>Our results revealed no statistically signifificant differences in LDL-C and TC between the two groups. Despite the lack of a statistically signifificant difference in the level of TG between the two groups, a declining trend was noted. A signifificant reduction of TG was observed in the yun-cai tea group at week 8, compared to baseline (P=0.048). The incidence of stomach discomfort, gastroesophageal reflfl ux, diarrhea, and constipation was slightly higher in the yun-cai tea group. No other signifificant adverse events were found.</p><p><b>CONCLUSION</b>It is unlikely that yun-cai tea used had a blood lipid reduction effect. Further larger scale clinical trials with a longer duration and larger dose are necessary.</p>
