This study aims to explore the synergistic effects of the main components in salvianolic acids for Injection(SAFI) on key pathological events in cerebral ischemia, elucidating the pharmacological characteristics of SAFI in neuroprotection. Two major pathological gene modules related to endothelial injury and neuroinflammation in cerebral ischemia were mined from single-cell data. According to the topological distance calculated in network medicine, potential synergistic component combinations of SAFI were screened out. The results showed that the combination of caffeic acid and salvianolic acid B scored the highest in addressing both endothelial injury and neuroinflammation, demonstrating potential synergistic effects. The cell experiments confirmed that the combination of these two components at a ratio of 1∶1 significantly protected brain microvascular endothelial cells(bEnd.3) from oxygen-glucose deprivation/reoxygenation(OGD/R)-induced reperfusion injury and effectively suppressed lipopolysaccharide(LPS)-induced neuroinflammatory responses in microglial cells(BV-2). This study provides a new method for uncovering synergistic effects among active components in traditional Chinese medicine(TCM) and offers novel insights into the multi-component, multi-target acting mechanisms of TCM.

Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

ObjectiveTo further study the pathogenic role of different types of Chlamydia trachomatis （CT） proteins in tubal factor infertility， evaluate the clinical detection value of Chlamydia trachomatis protein antibody in predicting tubal factor infertility. MethodsA total of 58 cases of tubal factor infertility （TFI）， 41 cases of fertile controls （FC） and 18 cases of infertile controls （IFC） were included. For serum detection， first， CT-IgG ELISA kit was used to detect the expression of CT-IgG in serum of three groups of people； then， 6 kinds of Chlamydia trachomatis proteins were expressed and purified in the early stage to establish the antibody test for these proteins， and ELISA detection method was used to detect the expression of their antibodies in the serum of TFI group， FC group and IFC group， respectively； and finally， the antibody OD value of the 6 kinds of Chlamydia trachomatis proteins in the three groups of subjects were statistically described， and CT-IgG was used as the reference standard to draw the receiver operating characteristic curve （ROC curve） of each CT antibody. The Youden Index determines the cutoff value for each antibody. Taking TFI as the reference class， two disordered multiple classification logistic regression models were established with the FC and IFC groups， respectively； and the reference class was used to explore the value of various antibodies and age in predicting TFI， FC and IFC of Chlamydia trachomatis. The back-off method was used to screen the variables. ResultsThe OD value of CT376 antibody in the TFI group was higher than that in the FC group （0.86 vs. 0.60， P=0.026）. The CT376 antibody OD value in the TFI group was higher than that in the IFC group （0.86 vs. 0.64， P=0.026）. The CT443 antibody OD value in the IFC group was higher than that in the TFI group （0.59 vs. 0.34， P=0.036） and higher than that in the FC group （0.59 vs. 0.30， P=0.02）. The multiple classification logistic regression analysis established between TFI and FC showed that CT-IgG ［P<0.001， OR=0.084， 95%CI （0.025， 0.284）］， CT376 antibody ［P=0.068， OR=0.359， 95%CI （0.120， 1.078）］. CT-IgG is an independent risk factor for tubal infertility， and CT376 antibody cannot be an independent risk factor for tubal infertility. The multiple classification logistic regression analysis established between TFI and IFC showed that among infertile patients， CT-IgG ［P<0.05， OR=0.194， 95%CI （0.046， 0.817）］， CT376 antibody ［P<0.05， OR=0.176， 95%CI （0.038， 0.818）］ and CT381 antibody ［P<0.05， OR=0.112， 95%CI （ 0.016， 0.796）］ were independent risk factors for tubal infertility. ConclusionThe expression of CT376 antibody in tubal infertility patients is higher than that in fertile and infertile controls， suggesting that CT-induced tubal factor infertility may be related to CT376. CT-IgG， and CT376 antibodies are meaningful in predicting CT-induced tubal factor infertility.

OBJECTIVE: To investigate the expression of CSF3R mutation in acute myeloid leukemia (AML) and analyze its clinical characteristics and prognosis. METHODS: A retrospective study was conducted in 212 patients with AML who were newly diagnosed in the Second Hospital of Shanxi Medical University from January 1th 2018 to June 30th 2021, including 22 patients with CSF3R mutations as mutation group and 190 patients with CSF3R wild type ［66 cases of them were screened by propensity score matching (PSM), as control group］. The early efficacy and survival between the two groups were compared. RESULTS: The median age of patients in the mutation group was 50(17-73) years old, and the ratio of male to female was 1.2:1 The main types were AML with maturation (11 cases) and acute myelomonocytic leukemia (9 cases). Prognostic stratification was carried out according to the risk stratification system of the European leukemia network in 2017, with 16 cases (72.73%) in the middle and high-risk group. At the initial diagnosis, the median count of white blood cell (WBC) was 44.75(1.30-368.71)×10⁹/L, among which 15 cases (68.18%) were >10×10⁹/L, and the median count of platelet (PLT) was 24(4-55)×10⁹/L. CSF3R T618I (68.18%) was a common mutation site, which had concomitant gene mutations, in which CEBPA mutation was the most common (10 cases, 45.45%), but only existed in CSF3R T618I mutation. The CR/CRi rate was 68.18% and 71.21% in the mutant group and the control group (P >0.05), the median over all survival time was 15 months and 9 months (P >0.05), and the median disease-free survival time was 8 months and 4 months (P >0.05), respectively. CONCLUSION Most AML patients with CSF3R mutation are middle-aged patients, the main types are AML with maturation and acute myelomonocytic leukemia, and most of them have middle and high-risk prognosis. CSF3R mutation may not be an independent prognostic marker for newly diagnosed AML patients.

Objective: To evaluate the association between pre-and post-diagnosis body mass index (BMI) and risk of colorectal cancer (CRC) death. Methods: The cohort consisted of 3, 057 CRC patients from Shanghai who were diagnosed from Jan. 1, 2009 to Dec. 31, 2011 and aged from 20 to 74 years. The pre- and post-diagnosis BMI and clinical and lifestyle factors were collected at baseline. Death information was collected using record linkage with the Shanghai Cancer Registry and telephone confirmation during follow-up by the end of 2019. The Cox proportional regression model was used to estimate HR with 95% CI. Results: Analysis by multivariable Cox model showed no association between pre-diagnosis BMI and death risk in both male and female patients. Male patients with a post-diagnosis underweight BMI had an elevated risk of death compared to those in normal weight (HR=1.69, 95% CI: 1.21-2.37), especially in early stage cases. Overweight patients (HR=0.74, 95% CI: 0.61-0.89) and patients with obesity class Ⅰ (HR=0.63, 95% CI: 0.45-0.89)had better survival with decreased risks of death, especially in advanced stage cases. The decreased death risk in patients with obesity class Ⅱ was not significant (HR=0.57, 95% CI: 0.24-1.39). The P(trend) value for decreased risk of death with increased BMI in female patients was statistically significant (P<0.001), and the overweight and obesity class Ⅰ categories had better survival in advanced stage(HR(overweight)=0.62, 95% CI: 0.42-0.93; HR(obesity class Ⅰ)=0.39, 95% CI: 0.16-0.98). Both male and female patients with post-diagnosis BMI loss >2.0 kg/m(2) had an increased death risk when compared with those with stable BMI (change≤1.0 kg/m(2)) between pre- and post-diagnosis. BMI gain after diagnosis did not change death risk. Conclusions: Post-diagnosis BMI in the overweight or obesity class Ⅰ groups might be conducive to prolonging male CRC patients' survival, while underweight might result in poor prognosis. Keeping weight and avoiding excessive weight loss should be suggested for all CRC patients after diagnosis.

Background: Insulin-treated patients with long duration of type 2 diabetes mellitus (T2DM) are at increased risk of ketoacidosis related to sodium-glucose co-transporter 2 inhibitor (SGLT2i). The extent of circulating ketone elevation in these patients remains unknown. We conducted this study to compare the serum ketone response between dapagliflozin, an SGLT2i, and sitagliptin, a dipeptidyl peptidase-4 inhibitor, among insulin-treated T2DM patients. Methods: This was a randomized, open-label, active comparator-controlled study involving 60 insulin-treated T2DM patients. Participants were randomized 1:1 for 24-week of dapagliflozin 10 mg daily or sitagliptin 100 mg daily. Serum β-hydroxybutyrate (BHB) levels were measured at baseline, 12 and 24 weeks after intervention. Comprehensive cardiometabolic assessments were performed with measurements of high-density lipoprotein cholesterol (HDL-C) cholesterol efflux capacity (CEC), vibration-controlled transient elastography and echocardiography. Results: Among these 60 insulin-treated participants (mean age 58.8 years, diabetes duration 18.2 years, glycosylated hemoglobin 8.87%), as compared with sitagliptin, serum BHB levels increased significantly after 24 weeks of dapagliflozin (P=0.045), with a median of 27% increase from baseline. Change in serum BHB levels correlated significantly with change in free fatty acid levels. Despite similar glucose lowering, dapagliflozin led to significant improvements in body weight (P=0.006), waist circumference (P=0.028), HDL-C (P=0.041), CEC (P=0.045), controlled attenuation parameter (P=0.007), and liver stiffness (P=0.022). Average E/e’, an echocardiographic index of left ventricular diastolic dysfunction, was also significantly lower at 24 weeks in participants treated with dapagliflozin (P=0.037). Conclusion Among insulin-treated T2DM patients with long diabetes duration, compared to sitagliptin, dapagliflozin modestly increased ketone levels and was associated with cardiometabolic benefits.

OBJECTIVE: To investigate the baseline levels of microorganisms' growth on the hands of anesthesiologists and in the anesthesia environment at a cancer hospital. METHODS: This study performed in nine operating rooms and among 25 anesthesiologists at a cancer hospital. Sampling of the hands of anesthesiologists and the anesthesia environment was performed at a ready-to-use operating room before patient contact began and after decontamination. RESULTS: Microorganisms' growth results showed that 20% (5/25) of anesthesiologists' hands carried microorganisms (> 10 CFU/cm ²) before patient contact began. Female anesthesiologists performed hand hygiene better than did their male counterparts, with fewer CFUs ( P = 0.0069) and fewer species ( P = 0.0202). Our study also found that 55.6% (5/9) of ready-to-use operating rooms carried microorganisms (> 5 CFU/cm ²). Microorganisms regrowth began quickly (1 hour) after disinfection, and increased gradually over time, reaching the threshold at 4 hours after disinfection. Staphylococcus aureus was isolated from the hands of 20% (5/25) of anesthesiologists and 33.3% (3/9) of operating rooms. CONCLUSION Our study indicates that male anesthesiologists need to pay more attention to the standard operating procedures and effect evaluation of hand hygiene, daily cleaning rate of the operating room may be insufficient, and we would suggest that there should be a repeat cleaning every four hours.

Yi Yin, a famous medical scientist and culinary master in the late Xia Dynasty and early Shang Dynasty, developed the Chinese medicinal liquids and Chinese medicinal prescriptions emerged after that. Chinese medicinal prescriptions have attracted much attention because of their unique advantages in the treatment of chronic multifactorial diseases, representing an important direction of drug discovery in the future. Yiyin decoction theory is the superior form of personalized combined medication with advanced consciousness. It is different from not only the magic bullet theory of single component action but also the connotation of modern multi-target drugs. The core of Yiyin decoction theory can be summarized as compound compatibility, multiple effects, and moderate regulation. Compound compatibility refers to that the formulation of Chinese medicinal prescriptions involves the complex synergy and interactions between sovereign, minister, assistant, and guide medicinal materials. Multiple effects mean that the prescriptions employ a variety of mechanisms to exert comprehensive pharmacological effects of nonlinear feedback. Moderate regulation reflects that the prescriptions can accurately regulate the multiple points of the disease biological network as a whole. To solve the mystery of Yiyin decoction theory, we should not only simply study the known active substances(components) and their independent target effects in the mixture, but also mine the "dark matter" and "dark effect" of Chinese medicinal prescriptions. That is, we should learn the neglected atypical pharmacological effects of Chinese medicinal prescriptions and the multi-point nesting mechanism that plays a precise regulatory function in the body. Yiyin decoction theory focuses on the overall pharmacological effect to reflect the comprehensive clinical value of Chinese medicinal prescriptions, which is of great significance for the development of a new model for the evaluation and application of new Chinese medicinal prescriptions in line with the theory of traditional Chinese medicine.
