Terpine-4-ol is abundant in nature. As a cyclic monoterpenoid compound, terpine-4-ol is distributed in a variety of natural plants. It is the main component and the key active substance in many traditional Chinese essential oils, such as Melaleuca alba essential oil and coral ginger essential oil. Terpine-4-ol has anti-microbial, anti-tumor, insecticidal, anti-inflammatory, and other effects. It can treat cancer, as well as oral and cardiovascular diseases with great safety. In terms of antibacterial activity, terpine-4-ol can destroy bacterial cell walls, improve membrane permeability, and regulate bacterial migration, reproduction, and other related genes to inhibit bacterial activity. In terms of antifungal activity, terpine-4-ol can bind with ergosterol in fungal cell walls to cause fungal death. In terms of insecticidal activity, terpine-4-ol can inhibit Na+ and K+-ATPase activity and cause the death of the insect. In terms of anticancer activity, terpine-4-ol can regulate the expression of apoptosis-related proteins in cancer cells, so as to control the apoptosis of cancer cells. In this paper, the pharmacological activity and action mechanism of terpine-4-ol were reviewed to provide a reference for further research and utilization of terpine-4-ol.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Dysmenorrhea is a common gynecological disease in clinic, with primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea is usually not accompanied by organic lesions in genital organs, which is mainly related to the increase of prostaglandin content in endometrium during menstruation. Secondary dysmenorrhea is accompanied by organic lesions of reproductive organs, often associated with local lesions of reproductive organs, but also with patients' mental factors and neuroendocrine factors.The incidence of dysmenorrhea is as high as 73.8%, and there is no radical cure method, which has a great impact on the life, work and learning of patients. Chinese medicine essential oil widely exists in aromatic Chinese medicine, with antibacterial, antioxidant and anticancer activities. It can regulate neuroendocrine function, anti-inflammatory and analgesic effects, and improve mood by regulating the levels of prostaglandins, oxytocin and other hormones in the body and regulating the emotions of patients, there by alleviating dysmenorrhea to a certain extent. In recent years, many scholars have made more in-depth research on Chinese medicine essential oil in alleviating dysmenorrhea, but there is a lack of comprehensive collation of such studies. In this regard, the author has systematically sorted out the generation and classification of dysmenorrhea, the mechanism of action of essential oil of traditional Chinese medicine to alleviate dysmenorrhea and the application of essential oil of traditional Chinese medicine in the field of dysmenorrhea by consulting relevant literature in Chinese and foreign languages in recent years, so as to provide reference for the treatment of dysmenorrhea.

To investigate the feasibility and clinical efficacy of free graft of vascularized iliac bone flap based on deep iliac circumflex vessels for the treatment of osteonecrosis of femoral head (ONFH). Methods Twelve cases of ONFH(13 hips) received free graft of vascularized iliac bone flap based on deep iliac circumflex ves-sels from April, 2016 to July, 2017.The average Harris score was (74.7±6.9) in the second stage and (68.6±9.2) in the third stage. After debriding the necrosis bone of the femoral head, the contralateral vascularized iliac bone flap had been harvested, and then implanted into the femoral head. The deep iliac circumflex artery and its accompanying vein were anastomosed with the transverse branch (or ascending branch) of the lateral circumflex femoral artery and con-comitant vein respectively. The herringbone brace was used for hip fixation for 3 weeks after operation. X-ray exami-nation (1, 3, 6, 9 and 12 months after operation, respectively) and Harris hip score (6 and 12 months after operation, respectively) were performed to evaluate the recovery results of the femoral head. Scores were recorded and analyzed by paired t-test.The difference was considered to statistically significant if P<0.05. Results The patients were fol-lowed-up for 15(12-20)months. The iliac bone flap of 12 patients (13 hips) healed well. There was no necrosis and collapse in 12 hips, except 1 femoral head collapsed slightly because of weight loading too early. The average Harris score was (91.6±4.5) of the second stage and (84.8±6.1) of the third stage. Compared with scores before the operation, the difference was statistically significant (P<0.05). Conclusion Free vascularized iliac bone grafting based on deep iliac circumflex vessels is an ideal treatment for ONFH head in middle and advanced stage.
