Objective: To observed the effect of a curcumin-based vaginal gel combined with electroporation for the treatment of vulvovaginal candidiasis (VVC) caused by Candida albicans. Methods: Temperature-sensitive in situ gels (ISG) were prepared using poloxamers 407 and 188 as matrices. The mass ratio of poloxamer 407 and poloxamer 188 was 7:1 with a gelation temperature of approximately 29°C and gelation time of 2.5 min. Results: Electroporation increased the transmucosal permeability of the model drug, doxorubicin and improved the antifungal effects of curcumin. In vitro antifungal experiments showed that the number of fungal colonies in curcumin ISG combined with electroporation was lower than that in pure curcumin ISG. In vivo pharmacodynamic experiments showed that, compared to the model group, curcumin ISG with electroporation inhibited the growth of C. albicans, alleviated vaginal mucosal edema, and reduced the inflammatory response. Conclusion Curcumin ISG combined with electroporation has substantial potential for the efficient clinical treatment of VVC.

Aim To analyze the incidence of major adverse cardiovascular and cerebrovascular events(MACCE)in patients with different types of acute coronary syndrome(ACS)undergoing coronary artery rotational atherec-tomy(RA)within two years.Methods 268 patients with ACS who underwent RA in the Department of Cardiology,Nanjing Drum Tower Hospital,Affiliated Hospital of Medical School of Nanjing University,between November 2011 and December 2022 were retrospectively included.According to whether ST-segment elevation myocardial infarction(STEMI)occurred,they were divided into 25 cases in the ST-segment elevation myocardial infarction(STEMI)group and 243 cases in the non-ST-segment elevation acute coronary syndrome(NSTE-ACS)group.The NSTE-ACS group included unstable angina pectoris(UAP)and non-STEMI(NSTEMI).The basic information and intraoperative data related to percutaneous coronary intervention(PCI)in the two groups were collected,and the occurrence of MACCE(including car-diovascular death,non fatal myocardial infarction,worsening heart failure,ischemic stroke and target vessel revasculariza-tion)within two years after RA was followed up and analyzed.Results Compared with the NSTE-ACS group,the STEMI group had a higher incidence of MACCE and cardiovascular mortality during the two-year follow-up period(10.3％and 0.4％vs.28.0％and 8.0％;P＜0.05).There was no statistical difference between the incidence of target vessel revascularization,nonfatal infarction,ischemic stroke and worsening heart failure between the two groups(P＞0.05).According to subgroup analysis based on enrollment periods,the results showed that over time(2011-2017 compared to 2018-2022),the incidence of MACCE in all patients within two years after RA showed a decreasing trend(18.97％vs.6.58％).Combined with previous studies,gender,hypertension,diabetes,renal insufficiency,smoking and left ven-tricular ejection fraction(LVEF)were included in the Cox regression model.It was found that the use of intravascular ul-trasound(IVUS)was an independent factor to reduce the incidence of MACCE in ACS patients within two years after RA(HR=0.333,95％CI:0.153～0.723,P＜0.01).Kaplan-Meier analysis showed that among ACS patients undergoing RA,the cumulative incidence of MACCE events was higher in the STEMI group than that in the NSTE-ACS group(P＜0.05).Conclusion STEMI patients have a higher incidence of MACCE and cardiovascular mortality within two years after RA compared to NSTE-ACS patients,and the use of IVUS during RA surgery can reduce the incidence of MACCE in ACS patients after RA.

Objective: To analyze the expression of sigma factor in drug resistance gene mutations of Mycobacterium tuberculosis (MTB), so as to provide a reference for the drug resistance mechanism of tuberculosis. Methods: Clinical sputum specimens of outpatients at Tianjin Center for Tuberculosis from 2018 to 2022 were collected. A total of 899 MTB-positive strains were obtained by culture, and 492 phenotypically sensitive strains and 407 phenotypically resistant strains were identified by an in vitro phenotypic drug susceptibility test. Thirty drug-sensitive strains of MTB were randomly selected, and 98 drug-resistant strains with specific resistance phenotypes were chosen; all were subjected to melting curve analysis for detection of drug-resistance gene mutations. The strains were divided into sensitive strains without gene mutation, isoniazid-resistant strains with inhA mutation or katG mutation, rifampicin-resistant strains with rpoB mutation, and multigene mutation-resistant strains with inhA+rpoB mutation or katG+rpoB mutation. The mRNA relative expression of sigma factor was detected by fluorescence quantitative PCR, and the ratio of sigma factor mRNA relative expression between the experimental strain and the standard strain >2 was used to screen for highly expressed sigma factor. The differences in sigma factor mRNA relative expression and high expression rate between drug-resistant gene mutant strains and sensitive strains were analyzed. Results: Thirty sensitive strains and 90 drug-resistant strains were included. Among them, there were 16 strains with inhA mutation, 22 strains with katG mutation, 13 strains with rpoB mutation, 15 strains with inhA+rpoB mutation, and 24 strains with katG+rpoB mutation. Compared to the sigma factors of the sensitive strains, the mRNA expression levels of sigG and sigI in inhA-mutated strains, sigF, sigG, sigH, sigI, sigJ, and sigL in katG-mutated strains, and sigF, sigG, sigH, sigJ, and sigL in rpoB-mutated, inhA+rpoB-mutated, and katG+rpoB-mutated strains were significantly higher (all P<0.05). Additionally, the high-expression rates of sigI in inhA-mutated strains, sigF, sigG, sigI, sigJ, and sigL in katG-mutated and inhA+rpoB-mutated strains, and sigF, sigG, sigH, sigJ, and sigL in rpoB-mutated and katG+rpoB-mutated strains were also higher (all P<0.05). Conclusion Compared to sensitive MTB strains, sigI showed higher relative expression of mRNA and high-expression rate in inhA-mutated strains, and sigF, sigG, sigJ, and sigL had higher mRNA relative expression and high-expression rates in katG-mutated, rpoB-mutated, and multi-drug-resistant strains.

[Objective]To investigate and explore the characteristics and influencing factors of glucose metabolism in children with β-thalassemia major(β-TM)after allogeneic hematopoietic stem cell transplantation(allo-HSCT).[Methods]The follow-up data of 41 patients with β-TM who underwent HSCT at Hematopoietic Stem Cell Transplantation Department of Children's Medical Center of Sun Yat-sen Memorial Hospital,Sun Yat-sen University were retrospectively analyzed.Their glucose metabolism characteristics were evaluated through laboratory tests and the related influencing factors were analyzed.[Results]In the study,41.46％(17/41)of patients developed abnormal glucose homeostasis after HSCT.Among them,82.35％(14/17)characterized by insulin resistance,but no cases of diabetes mellitus were found.The results of insulin releasing test and oral glucose tolerance test(OGTT)showed that 45.00％(9/20)of patients had abnormal insulin releasing curve and 40.0％(8/20)had delayed serum glucose peak.The average age of HSCT in abnormal glucose homeostasis group was significantly older than that in the normal glucose homeostasis group[(8.8±3.9)years old vs(6.0±3.1)years old,P=0.015].[Conclusions]Patients with β-TM after HSCT may develop abnormal glucose homeostasis,consists largely of insulin resistance.The elder age of HSCT(≥7 years old)is a risk factor for abnormal glucose homeostasis in β-TM patients after HSCT.It is recommended to regularly monitor glucose metabolism indicators in β-TM children after HSCT,especially in elderly transplant recipients.

With the rapid development of social economy， the number of patients with nervous system diseases has increased， and the incidence of the population has a trend of younger， which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua， a Chinese medicinal material. Artemisinin and its derivatives， in addition to the antimalarial effect， also have anti-parasitic， anti-fungal， anti-viral， hypoglycemic， hypolipidemic， anti-tumor， and anti-inflammatory effects， showing a wide range of pharmacological activities. In the past five years， research on the new pharmacological effects of artemisinin and its derivatives has been deepening， and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention， including anti-neuroinflammation， anti-oxidative stress， maintaining the stability of the blood-brain barrier， regulating the release of neurotransmitters， repairing neuronal damage， and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019－2024， this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke， neurodegenerative diseases， neuroimmunological diseases， neuralgia， and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs， innovative drug development， and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases， including hypertension， arrhythmia， and heart failure， is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter， nitrogen dioxide， ozone， carbon monoxide， and sulfur dioxide are closely related to the occurrence of cardiovascular diseases， and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024， this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress， inflammatory response， thrombosis， extracellular vesicle release， endoplasmic reticulum stress， apoptosis， endothelial dysfunction， autonomic nervous system imbalance， and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases， the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases， providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated， becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist （GLP1-RA） and sodium glucose cotransporter-2 inhibitors （SGLT2） are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports， this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases （e.g.， hyperglycemia， insulin resistance， and inflammation）， related targets such as apolipoprotein C-Ⅲ （APOC3）， S100 calcium-binding protein A8/A9 （S100A8/A9）， growth/differentiation factor-15 （GDF-15）， and NACHT， LRR， and PYD domains-containing protein 3 （NLRP3）， advanced glycation end products， insulin resistance， endothelial dysfunction， endoplasmic reticulum stress， mitochondrial dysfunction， and intestinal flora disorder. In addition， this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients （e.g.， baicalein， puerarin， curcumin， notoginsenoside， and tanshinone Ⅱ_A）， single herbal medicines （e.g.， Astragali Radix， Ginseng Radix et Rhizoma， Sophorae Flavescentis Radix， Cinnamomi Cortex， and Corni Fructus）， and compound formulas （e.g.， Buzang Tongluo Fang， Yiqi Yangyin Huoxue Fang， Shenqi Fang， Huangqisan， Danggui Buxue Tang， and Liuwei Dihuang Wan） of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress， ameliorating dyslipidemia and insulin resistance， protecting islet β cell function， repairing endothelial damage， inhibiting smooth muscle cell proliferation， foam cell formation， macrophage polarization， and cardiac hypertrophy and fibrosis， and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B （IRS/PI3K/Akt）， peroxisome proliferator-activated receptor α/γ （PPAR α/γ）， nuclear factor-kappa B （NF-κB）， adenosine 5′-monophosphate （AMP）-activated protein kinase （AMPK）， hypoxia-inducible factor-1-BCH domain-containing protein （HIF-1-BNIP）， vascular endothelial growth factor/hypoxia-inducible factor-1α （VEGF/HIF-1α） and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.

Objective To study the influence of long term simulated weightlessness on occurrence of laryngopharyngeal reflux(LPR)in healthy volunteers by detection of pepsin in saliva.Methods During a 90-day head-down tilt bed rest(HDTBR)experiment,11 volunteers(4 from the control group and 7 from the countermeasure group)were recruited in the study in the following seven sessions:before bed rest session(Pre),during bed rest sessions for 3 days(BR3),31 days(BR31),61 days(BR61),85 days(BR85)and post bed rest sessions for 7 days(R7)and 25 days(R25).During each testing session,saliva samples were collected for two consecutive days both in the morning and at night before sleeping.Then pepsin in the saliva was measured by enzyme-linked immunosorbent assay.Scale of otorhinolaryngological symptoms for the duration of"Pre-,During-and Post-"were retrospectively performed.Results Among 288 saliva samples of 11 volunteers,17 saliva samples of 8 volunteers were positive for pepsin.The incidence of LPR was 9.1%(1/11)in the Pre session,and it increased to 36.4%in the BR31 session which was higher than the following consequential sessions(0%in BR31,27.3%in BR61 and 27.3%in BR85).Intriguingly,it rose again to 45.5%in R7 session and decreased to 9.1%until in R25 session.There was no significant difference between the control group and the countermeasure group.Total scores for the scale of otorhinolaryngological symptoms showed that a slight elevation tendency emerged during HDTBR session,compared with the pre-HDTBR session.It recovered during the post bed rest sessions.Conclusion The laryngopharyngeal reflux was found in the Pre,During and Post HDTBR experiment.The incidence was significantly increased both in the BR3 and R7 sessions,which indicates that the change of the posture with the stimulation of gastrointestinal dynamic conditions,despite the changes from vertical to horizontal or from horizontal to vertical,might be the major impact factor contributing to the elevation tendency of the incidence of laryngopharyngeal reflux.

Objective: To find a viable alternative to reduce the number of doses required for the patients with post-traumatic stress disorder (PTSD), and to improve efficacy and patient compliance. Methods: In this study, we used ginger oil, a phytochemical with potential therapeutic properties, to prepare ginger oil patches. High-performance liquid chromatography (HPLC) was used to quantify the main active component of ginger oil, 6-gingerol. Transdermal absorption experiments were conducted to optimize the various pressure-sensitive adhesives and permeation enhancers, including their type and concentration. Subsequently, the ginger oil patches were optimized and subjected to content determination and property evaluations. A PTSD mouse model was established using the foot-shock method. The therapeutic effect of ginger oil patches on PTSD was assessed through pathological sections, behavioral tests, and the evaluation of biomarkers such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), brain-derived neurotrophic factor (BDNF), and melatonin (MT). Results: The results demonstrated that ginger oil patches exerted therapeutic effects against PTSD by inhibiting inflammatory responses and modulating MT and BDNF levels. Pharmacokinetic experiments revealed that ginger oil patches maintained a stable blood drug concentration for at least one day, addressing the rapid metabolism drawback of 6-gingerol and enhancing its therapeutic efficacy. Conclusions Ginger oil can be prepared as a transdermal drug patch that meets these requirements, and the bioavailability of the prepared patch is better than that of oral administration. It can improve PTSD with good patient compliance and ease of administration. Therefore, it is a promising therapeutic formulation for the treatment of PTSD.
