RESUMO

Objective To observe the clinical efficacy of modified Huanglian Wendan Decoction for treatment of tic disorder (TD) children with syndrome of wind stirring due to phlegm-heat; To detect its effects on peripheral-blood miR-429 expression. Methods Eighty cases of TD children were randomly divided into treatment group and control group,with 40 cases in each group.In the treatment group,children were treated with modified Huanglian Wendan Decoction, one dosage a day, twice a day, orally. In the control group, TD children were treated with haloperidol, 0.03 mg/(kg?d), orally, according to the symptom to adjust dose, and the maximum amount did not exceed 0.08 mg/(kg?d). 30 d was a treatment course for both groups. The treatment lasted for three courses. Before and after 3 months of clinical observation, the severity of disease was evaluated by TCM syndrome and Yale Global Tic Severity Scale (YGTSS) score. Clinical efficacy and TCM syndrome efficacy were evaluated; the level of miR-429 in peripheral blood was detected; the adverse reactions were observed. Results The total effective rate of clinical efficacy was 82.5% (33/40) in treatment group and 80.0% (32/40) in the control group, without statistical significance (P>0.05); The total effective rate of TCM syndrome efficacy was 92.5% (37/40) in treatment group and 75.0% (30/40) in the control group, with statistical significance (P<0.05). Compared with before treatment, the YGTSS score and TCM syndrome score significantly decreased after treatment (P<0.01), and the TCM syndrome score in the treatment group was much lower than the control group after treatment (P<0.05). Compared with before treatment, miR-429 level in both groups increased obviously after treatment (P<0.01), and the miR-429 level in the treatment group was much higher than the control group after treatment (P<0.05). There were mild constipation (1 cases), diarrhea (2 cases), and anorexia (2 cases) in the treatment group, and obvious lethargy (3 cases) and dizziness (3 cases) in the control group. Conclusion Modified Huanglian Wendan Decoction shows obvious effects for treating TD, and can up-regulate miR-429 of peripheral-blood.

RESUMO

objective To evaluate the acute toxicity of recombinant trivalent human papillomavirus (HPV) vaccines.Methods Wistar rats were randomly divided into negative control and HPV groups with 20 rats in each group.Rats in HPV groups were sc administered with a single-dose of 1.5 mL of HPV vaccines (three times of human dose/each rat),while rats in negative control group were given equal volume of saline.The clinical state of animals was observed,and the body mass changes were detected.Rats were dissected after 15 d of treatment and examined by gross pathology.Results Following a single injection with high-dose HPV vaccines,there were not obvious abnormalities in clinical symptom.Compared with negative control group,the body weight of rats from HPV vaccines-treated group had no significant difference.No obvious macro-pathological change was found in all animals.Conclusion Single sc injection with recombinant trivalent HPV vaccines is well tolerated and no obvious toxicological change is found in Wistar rats.These results will facilitate further preclinical safety studies of HPV vaccines.

RESUMO

<p><b>BACKGROUND</b>Internal metallic stents have been widely used in clinical practice, but a high postoperative restenosis rate limits its application. The purpose of this study was to determine the effect of intrabiliary radiation on muscle formation and biliary duct remodeling after biliary duct balloon injury in dogs.</p><p><b>METHODS</b>Twenty male dogs (15 - 20 kg) were randomly divided into treatment group (n = 10) and control group (n = 10). Balloon overstretching injury was induced using a balloon catheter placed across the biliary duct. Subsequently, a 103Pd radioactive stent was positioned at the target site in each animal in the treatment group, providing the injured biliary duct with a radiation dose of 12.58 x 10(7) Bq. Dogs in the control group received Ni-Ti stents. All the dogs were killed one month after initial injury. The injured sections were dissected free from the dogs, and were processed for histological and morphological study. Cross-sections were stained with hematoxylin-eosin, Masson's trichrome, and Verhoef-van Giesen. Muscle formation area and lumen area were determined using a computer-assisted image analysis system.</p><p><b>RESULTS</b>Compared with the control group, 103Pd radioactive stents significantly reduced muscle formation area (78.3%, P < 0.01), and percentage area of stenosis [control stents: (60.0 +/- 21.6)%, 103Pd radioactive stents: (31.6 +/- 9.5)%]. In addition, in the treatment group, the biliary duct lumen area was significantly larger than that in the control group (P < 0.01).</p><p><b>CONCLUSIONS</b>103Pd radioactive stents providing a radioactive dose of 12.58 x 10(7) Bq are effective in reducing muscle formation and biliary duct remodeling after balloon overstretching injury.</p>
