The paper reviews systematically Professor FU Wenbin's academic thinking and clinical experience of integrative acupuncture-moxibustion therapy for cranial tinnitus. Professor FU believes that cranial tinnitus refers to psychosomatic comorbidity. This disease is associated mainly with the brain and liver in terms of the disease location. In pathogenesis, the dysfunction of qi movement, disharmony of internal organs and unhealthy conditions of body and mind are involved. In treatment, based on psychosomatic medicine, from the perspective of the integration of body and mind, and in line with the mode of the integrative acupuncture-moxibustion therapy, holistic regimens are used, including acupuncture, moxibustion, auricular acupuncture, etc. to consolidate the therapeutic effect of "tranquilizing the mind and relieving tinnitus".

(+)-Borneol, the main component of "Natural Borneol" in the Chinese Pharmacopoeia, is a high-end spice and precious medicine. Plant extraction cannot meet the increasing demand for (+)-borneol, while microbial biosynthesis offers a sustainable supply route. However, its production was extremely low compared with other monoterpenes, even with extensively optimizing the mevalonate pathway. We found that the key challenge is the complex and unusual dephosphorylation reaction of bornyl diphosphate (BPP), which suffers the side-reaction and the competition from the cellular dephosphorylation process, especially lipid metabolism, thus limiting (+)-borneol synthesis. Here, we systematically optimized the dephosphorylation process by identifying, characterizing phosphatases, and balancing cellular dephosphorylation metabolism. For the first time, we identified two endogenous phosphatases and seven heterologous phosphatases, which significantly increased (+)-borneol production by up to 152%. By engineering BPP dephosphorylation and optimizing the MVA pathway, the production of (+)-borneol was increased by 33.8-fold, which enabled the production of 753 mg/L under fed-batch fermentation in shake flasks, so far the highest reported in the literature. This study showed that rewiring dephosphorylation metabolism was essential for high-level production of (+)-borneol in Saccharomyces cerevisiae, and balancing cellular dephosphorylation is also helpful for efficient biosynthesis of other terpenoids since all whose biosynthesis involves the dephosphorylation procedure.

Objective To Investigate the effect of copper ions on the radiosensitivity of nasopharyngeal carcinoma(NPC)and identify potential targets to improve the efficacy of NPC radiation therapy.Methods The content of copper ions in normal nasopharyngeal epithelial cell line NP69 and a variety of NPC cell lines was detected by a copper microplate assay.After adding 0,5,10,20,50,100,200 μmol/L copper ion solution and 0,0.05,0.1,0.2,0.5,1.0,2.0 mmol/L TEPA solution,CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation.And determine the drug concentration to be used in subsequent experiments.CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation,and to determine the drug concentration used in the copper ion group and TEPA group in the subsequent experiments.CCK-8 assay and clone formation assay were used to detect the changes in radiosensitivity of NPC cells after drug treatment.The DNA damage and MAPK-ERK signaling pathway-related protein expression of NPC cells in each group before and after irradiation were detected by Western blot.Results The content of copper ions in NPC cells was significantly higher than that in normal naso-pharyngeal epithelial cells(P＜0.05).When the concentration of copper ion solution was lower than 50 μmol/L,the radiation resistance of CNE1 cells was improved,and the radiation sensitivity of SUNE1 cells was increased by 0.1～0.2 mmol/L TEPA(P＜0.05).Compared with the control group,the NPC cell radiotherapy resistance of copper ion group was enhanced,and the NPC cell radiotherapy sensitivity of copper ion group was enhanced(P＜0.05).Compared with the control group,the activation degree of MAPK-ERK pathway in copper ion group was up-regulated(P＜0.05).MAPK-ERK pathway inhibitor SCH772984 effectively reversed copper-mediated NPC radiotherapy resistance(P＜0.05).Conclusion The increased copper ion content in NPC cells promoted the radiotherapy resistance of NPC cells by activating the MAPK-ERK signaling pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background Preterm birth-related complications are the leading cause of death in newborns and children under the age of 5 years. Maternal heat exposure has been associated with both sleep status during pregnancy and the increased risk of preterm birth. However, whether sleep status could mediate the association between heat exposure and preterm birth remains unclear. Objective To evaluate the association between maternal heat exposure in early pregnancy and preterm birth, and to further explore potential mediation effect of sleep status on the association between heat exposure and preterm birth. Methods A birth cohort was established in Guangzhou Panyu Maternal Child Health Hospital (Guangzhou Panyu District He Xian Memorial Hospital) from 2017 until now. Pregnant women (with gestational age between 8 and 13 weeks) were included in this study when they presented to the hospital for their first prenatal care visit and signed an informed consent. Then they were followed up until delivery. A total of 3 268 pregnant women were included for the final analysis. Questionnaires were distributed to collect the demographic characteristics, lifestyles, and sleep status of pregnant women. Daily meteorological data during the study period were collected from meteorological monitoring stations in Guangzhou and the average ambient mean temperature of four weeks before the survey was calculated and assigned for each pregnancy. The 75th, 80th, 85th, 90th, and 95th percentiles (P₇₅, P₈₀, P₈₅, P₉₀, and P₉₅) of the average ambient temperature of all pregnant women were used as the thresholds to define heat exposure. Logistic regression was used to evaluate the effects of heat exposure in different definitions on preterm birth and sleep status (sleep duration, night sleep timing, and wake up timing). The mediation effects of sleep status on the relationship between heat exposure and preterm birth were also analyzed. Results Among all the included participants, 165 newborns were preterm births with an incidence rate of 5.0%. Heat exposures with thresholds of P₉₀ and P₉₅ increased the risk of preterm birth, with ORs (95%CIs) of 1.66 (1.04-2.57) and 1.90 (1.03-3.33), respectively (P<0.05). Heat exposures with thresholds of P₇₅, P₈₀, P₈₅, P₉₀, and P₉₅ decreased the sleep duration (<9 h vs. ≥9 h, control group: ≥9 h), and the ORs (95%CIs) were 1.51 (1.25-1.83), 1.44 (1.17-1.77), 1.35 (1.08-1.70), 1.43 (1.09-1.87), and 1.45 (1.00-2.13), respectively. Heat exposures with P₇₅ and P₈₀ thresholds resulted in earlier wake up timing (<8: 00 vs. ≥8: 00, control group: <8: 00), with ORs (95%CIs) of 0.77 (0.63-0.93) and 0.76(0.61-0.93), respectively. No significant association was observed between heat exposure and night sleep timing. The mediation analyses showed that under heat exposure with P₉₀ threshold, a statistically significant mediation effect was observed for sleep duration, and the proportion mediated was 6.07% (95%CI: 0.17%-25.00%) (P<0.05). No significant mediation effect was observed for night sleep timing and wake up timing. Conclusion An elevated risk of preterm birth after heat exposure in early pregnancy may be partly mediated through reducing sleep duration.
