ABSTRACT
ObjectiveTo study the effect of icariin on the proliferative capacity of hepatocellular carcinoma cell line CLC5 and the underlying mechanism. MethodThe targets of icariin were screened out by network pharmacology， and the target network and protein-protein interaction （PPI） network were constructed to predict the possible targets and pathways of icariin. CCK-8 assay was employed to explore the effects of different concentrations （0， 6.25， 12.5， 25， 50 μmol·L-1） of icariin on the viability of CLC5 cells. Further， CLC5 cells were treated with 0， 25， 50 μmol·L-1 icariin， and the effect of icariin on CLC5 cell proliferation was examined by Edu-488 assay and clone formation assay （CFA）. Western blot was employed to measure the expression levels of proteins in the protein kinase B （Akt）/glycogen synthase kinase 3β （GSK3β）/cell cycle-dependent kinase （CDK） pathway in the CLC5 cells exposed to different concentrations of icariin. ResultNetwork pharmacological analysis revealed that icariin may inhibit the hepatocellular carcinoma via cell cycle arrest and inhibition of tumor cell proliferation. Compared with the blank group， icariin decreased the viability of CLC5 cells in a time- and concentration-dependent manner （P<0.01） and reduced the positive rate of Edu-488 and the colonies in CFA （P<0.05， P<0.01）. Moreover， icariin down-regulated the protein levels of p-Akt， p-GSK3β， CDK4， and CyclinD1 （P<0.05， P<0.01）. ConclusionIcariin may block cell cycle to suppress the proliferation of CLC5 cells via inhibiting the Akt/GSK3β/CDK pathway.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the efficacy and safety of total glucosides of paeony capsule (TGPC) in patients with mild and moderate alopecia areata.</p><p><b>METHODS</b>A total of 86 outpatients were randomly allocated into two groups of TGPC (treatment, 44 cases) and compound glycyrrhizin tablet (control, 42 cases). The treatment group was given oral TGPC, three times daily and 600 mg per time; the control group was given oral compound glycyrrhizin tablets, three times daily and 50 mg per time. In addition, both groups were given 10 mg of vitamin B(2) and tapped the bold patches with massage. The treatment course was three months for both groups. Peripheral blood T-cell subsets (CD3(+)CD4(+), CD3(+)CD8(+), Th, Ts, Th/Ts) of 10 patients randomly selected from each group respectively were tested before and after three months of treatment. The effectiveness and adverse reaction of all cases were observed each month. The safety was evaluated according to the incidence rate of adverse reaction.</p><p><b>RESULTS</b>In the treatment group, the cured and markedly effective rate was 36.36% (16/44), 50.00% (22/44) and 68.18% (30/44) at the end of first, second and third month of treatment, respectively, and the incidence rate of adverse reaction was 13.64% (6/44). In the control group, the cured and markedly effective rate was 38.10% (16/42), 57.14% (24/42) and 71.43% (30/42), respectively, and the incidence rate of adverse reaction was 16.67% (7/42). The cured and markedly effective rate and the incidence rate of adverse reaction were similar in both groups (P>0.05). TGPC and compound glycyrrhizin tablet can inhibit CD3(+)CD4(+) and CD3(+)CD8(+), and decrease the ratio of Th/Ts (P<0.05).</p><p><b>CONCLUSION</b>TGPC is effective and safe in the treatment of alopecia areata.</p>

<p><b>OBJECTIVE</b>To observe the clinical curative effect of Chinese herbal medicine combined with acitretin capsule in treating psoriasis of blood-heat syndrome (P-BH).</p><p><b>METHODS</b>Eighty patients of P-BH were randomly assigned to two groups, 39 in Group A and 41 in Group B. Both was treated with Chinese herbal medicines for clearing heat, cooling blood and removing toxic substance, and acitretin capsule was given to Group A additionally, with 8 weeks as one therapeutic course. The clinical curative effect was compared between groups, and the change of psoriasis activity severe index (PASI) scores before and after treatment was observed.</p><p><b>RESULTS</b>The total effective rate in Group A was 84.2% and that in Group B 68.2%, also showing significance between groups (P<0.01). PASI score lowered significantly after treatment in both groups, showing statistical significance (P<0.01), but no significant difference between groups. Little adverse reaction was found in Group B, while in Group A, the adverse reaction was of even milder degree, which could be alleviated by adjusting the herbal medicine and symptomatic treatment administration.</p><p><b>CONCLUSIONS</b>The effect of Chinese herbal medicine combined with acitretin capsule was superior to Chinese herbal medicine alone in treating P-BH, but the adverse reaction of acitretin capsule could be alleviated by adjusting the herbs used. However, the result is waiting to be verified further by larger samples.</p>
