Qingchang suppositry induced remission in patients with mild-to-moderate ulcerative proctitis: a multicenter, prospective, randomized, parallel-controlled clinical trial.

OBJECTIVE: To evaluate the efficacy and safety of Qingchang suppository (, QCS), a preparation of Chinese herbal medicine, in the induction of remission in patients with mild-to-moderate ulcerative proctitis (UP). METHODS: We performed a multicenter, prospective, randomized, parallel-controlled trial to evaluate the efficacy of QCS induction therapy in 140 adult patients with mild-to-moderate UP and TCM syndrome of dampness-heat in large intestine. The patients were randomized to receive QCS (study group) or Salicylazosulfapyridine (SASP) suppository (control group) one piece each time, twice a day, per anum for 12 weeks. Mayo score and main symptoms score were evaluated at weeks 0, 2, 4, 8 and 12, rectosigmoidscopy was taken at weeks 0, 4, 8 and 12, Geboes score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and safety indexes were assessed at weeks 0 and 12. The primary efficacy endpoint is clinical remission rate, the secondary efficacy endpoints are clinical response rate, mucosa healing rate, Geboes score, the remission rates of the main symptoms, the median day to the remission of the symptom, etc. RESULTS: There were no statistical difference in the clinical remission rates, the clinical response rates, the mucosa healing rates, Geboes score, ESR and CRP between the two groups. The remission rates of tenesmus and anal burning sensation of the study group were significantly higher than those of the control group (76.5% vs 25.0%, P = 0.009; 74.51% vs 29.63%, P = 0.003). The median day to the remission of purulent bloody stool of the study group was significantly less than that of control group [11 (1, 64) vs 19 (2, 67), P = 0.007]. The patients receiving QCS had a significantly higher mucosa healing rate at week 4 than the patients receiving SASP suppository (71.42% vs 52.85%, P = 0.023). No adverse event occurred in the study group while the adverse events incidence of the control group was 5.7% (P = 0.049). CONCLUSIONS: QCS could induce the remission of UP as effectively and safely as SASP suppository, and was superior to SASP suppository in relieving the symptoms of tenesmus, anal burning sensation and purulent bloody stool and the time to reach mucosa healing.

Tumor necrosis factor-α inhibitors for the treatment of four cases of hidradenitis suppurativa / 中华皮肤科杂志

Four male cases of hidradenitis suppurativa (Hurley stage Ⅱ/Ⅲ) aged 20 - 45 years were collected from Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from August 2017 to December 2019. All the patients presented with sinuses, abscesses and scars on the buttocks, axillary and inguinal regions, and showed a poor response to previous treatment with antibiotics, glucocorticoids, retinoids, traditional Chinese medicine, etc. The patients were treated with intravenous drips of infliximab at a dose of 5 mg/kg at weeks 0, 2 and 6, followed by an every-9-week treatment regimen, or with subcutaneous injection of adalimumab at a dose of 80 mg at weeks 0 and 2, followed by an every-3-week regimen at a dose of 40 mg. Two patients experienced infusion reactions after intravenous drips of infliximab, and then were switched to adalimumab. Three of these patients achieved hidradenitis suppurativa clinical response, whereas 1 showed no response.

Study on tissue distribution of psoraleae fructus decoction in rats / 中国中药杂志

Advanced technologies are used to clarify the meridian tropism theory of traditional Chinese medicine is an important part of theoretical studies of traditional Chinese medicine. In this article, modern pharmacokinetic method was used to investigate tissue distribution characteristics of psoralen and isopsoralen of Psoraleae Fructus decoction in rats, in order to provide research ideas and experimental basis for the meridian tropism theory. In this study, various tissue samples such as heart, liver, spleen, lung, kidney, brain and spermary were collected at different times after oral administration with FP decoction, in order to determine concentration of psoralen and isopsoralen by HPLC. Pharmacokinetic parameters were calculated by DAS 2.0 software. The study results showed that HPLC indexes of psoralen and isopsoralen in various tissues of rats met the determination requirements of biological samples. Both components were distributed in all of the tissues, with AUC(0-t) order of liver > lung approximately kidney > heart > brain approximately spleen > spermary. There was significant difference between liver, kidney, lung and other tissues (P < 0.05). MRT(0-t) of both psoralen and isopsoralen were about 10 h. Therefore, psoralen and isopsoralen showed stronger targeting selection in liver, kidney and lung.

Effects of di'ao xinxuekang soft capsule on lipid peroxidation and the endothelial function in patients with coronary heart disease / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effects of Di' ao Xinxuekang Soft Capsule (DK) on the plasma levels of superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO), and endothelin (ET) in patients with coronary heart disease (CHD), and to study its underlying mechanisms.</p><p><b>METHODS</b>Totally 100 patients with CHD confirmed by coronary angiography were randomly assigned to two groups, the control group (60 cases) and the DK treatment group (40 cases). Patients in the control group received conventional therapy, while those in the DK treatment group received DK additionally. The therapeutic course for all was 3 months. The plasma levels of SOD, MDA, ET, and NO were determined pre-treatment, 4, 8, and 12 weeks after treatment.</p><p><b>RESULTS</b>Compared with before treatment, the serum levels of SOD and NO increased and the levels of MDA and ET decreased at each time point. Besides, better effects were obtained in the DK treatment group (P < 0.05).</p><p><b>CONCLUSION</b>DK possibly played a role in inhibiting lipid peroxidation and improving the endothelial dysfunction.</p>
