The purpose of this multi-institutional Phase II trial study was to prospectively investigate the efficacy of the herbal medicine TJ-14 for acute radiation-induced enteritis (ARE). TJ-14 was administered orally as a first-line treatment for ARE. The primary end point was efficacy at 1 week. The secondary end points were: (i) the efficacy of TJ-14 at 2 and 3 weeks after its administration, (ii) the quality of life score (FACT-G) at 1, 2 and 3 weeks after its administration, and (iii) adverse events. If the efficacy of TJ-14 was observed in eight patients or fewer, its efficacy was rejected. Results: Forty patients receiving pelvic radiotherapy were enrolled. Of these, 22 developed ARE and received TJ-14. Among these, 19 had cervical cancer and 9 received chemoradiotherapy. TJ-14 efficacy was shown in 19 out of the 22 patients (86%). Stool frequency per day at 1 week significantly decreased (mean ± SD: 4.9 ± 2.1 vs 3.7 ± 1.9, P = 0.02). This effect continued at 2 (2.2 ± 1.4, P = 0.004) and 3 weeks (2.1 ± 0.9, P = 0.05). Thirteen out of the 22 patients (59%) continued TJ-14 until the end of radiotherapy. FACT-G score deterioration was not observed after the administration of TJ-14. Grade 1 hypokalemia was observed in 4 patients, and Grade 1 constipation in 3. We concluded that TJ-14 is sufficiently promising to be examined in a Phase III trial. A randomized controlled trial is currently being planned.

Selecting Transfemoral Access or Upper Extremity Access for Renal Denervation Based on Vascular Morphology: Long-term Results.
J Clin Hypertens (Greenwich)

Department of Cardiology, National Center for Cardiovascular Diseases and Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Article Synopsis
- - The study compared the long-term effectiveness and safety of renal denervation through transfemoral access (TFA) and upper extremity access (UEA) in patients with resistant hypertension, analyzing data from 85 patients treated at Fuwai Hospital from 2012 to 2019.
- - Results indicated that TFA had a shorter fluoroscopy time, while both groups had similar procedure times and contrast volumes, with no serious complications reported.
- - Follow-up data showed no significant differences in blood pressure changes, antihypertensive medication use, or renal function between TFA and UEA, though more adverse events were reported in the TFA group without significant difference.
Interactions between natural products and cancer treatments: underlying mechanisms and clinical importance.

Natural products, also referred to as dietary supplements, complementary and alternative medicines, and health or food supplements are widely used by people living with cancer. These products are predominantly self-selected and taken concurrently with cancer treatments with the intention of improving quality of life, immune function and reducing cancer symptoms and treatment side effects. Concerns have been raised that concurrent use may lead to interactions resulting in adverse effects and unintended treatment outcomes.

Article Synopsis
- Weak acids with pH values between 4-7 are linked to gastroesophageal reflux disease (GERD) symptoms, particularly heartburn, by increasing production of prostaglandin E (PGE).
- This study found that weak acids elevate PGE levels in both normal and cancerous esophageal cells, with the most significant production occurring at pH 4-5.
- The research suggests that targeting pH levels in the treatment of GERD could help alleviate symptoms, as interventions that inhibit certain pathways related to PGE production showed effectiveness.
