ABSTRACTIntroductionAllergic rhinitis has a severe impact on patients’ life quality, and the incidence rate keeps increasing. Moxibustion is widely used for treating allergic rhinitis, and quantity is the basis of moxibustion efficacy. The purpose of this study is to evaluate the relationship between the different quantities of moxibustion and the efficacy of moxibustion in the treatment of allergic rhinitis. This study may be conductive to the standardization of moxibustion and furnish the mechanism of dose-effect relationship of moxibustion with data and new ideas.Methods and analysisThis randomized, placebo-controlled clinical trial will include 33 patients with allergic rhinitis who will be randomly assigned into three groups in a 1:1:1 ratio: high-dose moxibustion group, low-dose moxibustion group and sham moxibustion control group. All groups will be treated once every other day, 20 days for one treatment course. And the patients will receive treatment for 2 courses with an interval of 2 days between courses. We will conduct a follow-up 30 days later after completion of treatments. The primary outcome measure is Total Nasal Symptom Score, carried out at baseline, 3, 6 and 10 weeks. Secondary outcome measure is Rhino Conjunctivitis Quality of Life Questionnaire, carried out at baseline, 6 and 10 weeks.Ethics and disseminationThis trail has been approved by the IRB of Shanghai TCM-Integrated Hospital, Shanghai University of TCM. The results of the trial will be disseminated in peer-reviewed journals.Trial registration numberChiCTR2100050373; Pre-results.Strengths and limitations of this studyA randomised, placebo-controlled and parallel clinical trial will be conducted to test if ginger interposed moxibustion would have curative effect on allergic rhinitis and reveal the preliminary dose-effect relationship of moxibustion.This study will set high-dose moxibustion group and low-dose moxibustion group to test if more quantities of ginger interposed moxibustion would achieve better therapeutic effects on allergic rhinitis.Further study should be carried out to test if the curative effect of ginger interposed moxibustion would be positively correlated with the quantities.

The clinical therapeutics of traditional Chinese medicine (TCM) constitutes a complicated process which involves theory, diagnosis, and formula prescription with specific herbal dosage. Zhang Zhong-Jing’s classic work, Treatise on Febrile and Miscellaneous Diseases, has been influencing TCM practice for almost 2000 years. However, during this extended period of time in Chinese history, the Chinese weight measurement system experienced noticeable changes. This change in the weight measurement system inevitably, and perhaps even negatively, affected TCM herbal dosage determination and treatment outcome. Thus, in modern society, a full understanding of the accuracy of herbal dose selection has a critical importance in the TCM daily practice of delivering the best treatment to the patients suffering from different illnesses. In the 973 Project of the Chinese National Basic Research Program, expert consensus on classic TCM formula dose conversion has been reached based on extensive literature review and discussion on the dose–effect relationship of classic TCM formulas. One “liang” (两) in classic TCM formulas is equivalent to 13.8[Formula: see text]g. However, based on many TCM basic and clinical studies of variable herbal formula prescriptions and herbal drug preparations, the rule of one liang equals 13.8[Formula: see text]g should be adjusted according to different disease conditions. Recommended by the committee on TCM formula dose–effect relationship of the China Association of Chinese Medicine and the World Federation of Chinese Medicine Societies, the following expert consensus has been reached: (i) One liang converts to 6–9[Formula: see text]g for the severely and critically ill patients. (ii) One liang converts to 3–6[Formula: see text]g for the patients suffering from chronic diseases. (iii) One liang converts to 1–3[Formula: see text]g in preventive medicine. The above conversions should be used as a future TCM practice guideline. Using this recommended guideline should enhance the effectiveness of daily TCM practice.

Abstract While dose escalation of radiotherapy (DERT) has failed to improve overall survival (OS) or progression-free survival (PFS) for glioblastoma in previous studies, a recent phase II clinical trial utilizing 18F-DOPA-PET-directed DERT demonstrated improved PFS in MGMT-unmethylated patients and OS in MGMT-methylated patients compared to historical controls. This planned secondary analysis sought to determine 1) how 18F-DOPA-PET changes RT volumes beyond standard MRI-planning, 2) which patients benefit most and least from this protocol, 3) which are mostly likely to experience clinically significant radionecrosis after DERT, and 4) patterns of failure after DERT. For 69 evaluable patients, median MRI-defined, PET-defined, and combined low-dose gross tumor volumes (GTV51) were 54 cc (range 9-248), 23 cc (0.4-179), and 62 cc (10-260), respectively. Median MRI-defined, PET-defined, and combined high-dose GTVs (GTV76) were 32 cc (range 4-136), 6 cc (0.1-138), and 34 cc (4-162), respectively. 18F-DOPA-PET resulted in a median volumetric expansion of 13% (0-243%) and 5% (0-217%) from MRI-defined low-dose and high-dose GTV’s, respectively. Central failures ( >95% of recurrence tumor volume) occurred within the 76 Gy, 60 Gy, and 51 Gy isodose lines in 32 (46%), 60 (87%), and 64 (93%) patients, respectively. Recursive partitioning analysis stratified patients by OS and PFS. Patients with 18F-DOPA-PET-defined GTV76 > 7.8cc, MRI-defined GTV76 > 42.7cc, and MGMT promotor-unmethylated tumors had the shortest OS, while patients with smaller PET and MRI-defined tumors had the longest OS (median 10.4 vs. 64.6 months, p< 0.001). Similarly, PFS was worst in patients with 18F-DOPA-PET-defined GTV76 > 2.17 cc who had biopsy only (median PFS 3.2 months, p< 0.001). Patients with 18F-DOPA-PET-defined GTV51 > 50 cc had the highest risk of grade 3+ radionecrosis (p< 0.001). In conclusion, larger 18F-DOPA-PET and MRI-defined tumor volumes were associated with worse outcomes, and 18F-DOPA-PET-directed DERT appears to reduce risk of central recurrence in high-dose volumes.

Objective: To study the effects of the ethnic medicine Polygala fallax Hemsl with Guangxi characteristics on the sex hormones and ?-EP in research objective perimenopausal rat models. Methods: 40 female SPF rats were randomly divided into 4 groups, including the normal, model, high-dose and low-dose groups. Rats of three groups except for the normal one were treated with perimenopausal modelling through the method of subcutaneous injection of compound 4-VCD for 15 consecutive days. Rats of the normal and model group were normally fed without any treatment. Rats of the high-dose and low-dose groups were administered by high- and low-dose intragastric administration of the extract of Polygala fallax Hemsl. According to the menstrual cycle of the vaginal smear of the rat, each menstrual cycle is a course of treatment and 6 consecutive courses of treatment would be given. The indexes of serum sex hormones (E2, FSH, LH) and ?-EP of rats in each group were observed after treatment. Results: After the treatment of 6 cycles, for the levels of ?-EP and E2, the model group was lowest (P<0.05), the normal group was highest (P<0.05); and the high-dose group was higher than the low-dose group; For the levels of FSH and LH, the normal group was lowest (P<0.05), the model group was highest (P<0.05), and the high-dose group was lower than the low-dose group. Conclusion: Guangxi characteristic national medicine Polygala fallax Hemsl can effectively improve the levels of serum sex hormones and ?-EP in perimenopausal rat models and relieve the related symptoms with a certain dose-effect relationship.

Background: To mitigate diabetes and its complications in cardiovascular diseases, the antidiabetic agent glimepiride is usually administered with ferulic acid concomitantly in clinics. However, both drugs are prone to be metabolized partly by CYP2C9, thus they have the potential drug-drug interaction affecting the safety and efficacy. Objective: This project aimed to evaluate the pharmacokinetic (PK) effects of ferulic acid (FA) on glimepiride (GLM) and its metabolite hydroxy glimepiride (OH-GLM) in plasma by using the HPLC-MS/MS method. Methods: Healthy male Sprague Dawley (SD) rats were randomly divided into three groups. They received intragastric administration of 0.5% sodium carboxymethyl cellulose (CMC), low-dose FA (20 mg•kg-1), and high-dose FA (40 mg•kg-1) for 8 days, respectively. Rats were given 0.5% sodium CMC or FA on the last day and then uniformly given 1.0 mg•kg-1 glimepiride by gavage. Blood samples were obtained from retro-orbital plexus at the time points of 0.167, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, and 24 h after administration. Plasma samples were analyzed for GLM and its metabolite OH-GLM on an HPLC-MS/MS system. Results: No statistically significant difference was found in the effect of low-dose FA on the pharmacokinetics of GLM. High-dose FA significantly decreased Cmax of GLM by 30.05% and CLz/F of OH-GLM by 47.45%. It also increased Tmax and t1/2z of GLM by 95.87% and 140.00%. Conclusion: Low-dose FA did not alter GLM metabolism, while high-dose treatment of FA caused pharmacokinetics interaction with GLM in rats.
