IgG4-related disease (IgG4-RD) is a newly recognized fibro-inflammatory condition of autoimmune etiology in recent twenty years, mainly manifesting as mass-forming lesions in single or multiple organs. In the past, it was often missed or misdiagnosed as inflammation or tumor. Patients may die from multiple organ failure due to end-stage fibrosis if they are not treated promptly. However, the number of clinically confirmed cases has gradually increased with the improvement of diagnostic level in recent years, and these patients have benefited greatly after receiving early treatment. Although patients generally respond well to traditional immunosuppressors including glucocorticoids and disease-modifying anti-rheumatic drugs, refractory and recurrent cases, even patients with glucocorticoid contraindication are common. Important mechanistic insights have been derived from studies of B-cell depletion therapy, but greater awareness of the pathophysiology of IgG4-RD is still badly needed to identify novel therapeutic targets. In this article, we reviewed the pathogenesis progress and promising therapy of IgG4-RD to seek better clinical management of IgG4-RD.

Diabetes & Metabolism Journal 2022;46(6):843-854
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.

In order to reveal the distribution and population characteristics of endophytic fungi from Zanthoxylum nitidum and the antibacterial potential,this study performed molecular identification and analyzed the genetic diversity and antibacterial activity of endophytic fungi from Z. nitidum in Guangxi. Through culture and molecular identification,35 strains,belonging to 15 genera,12 families,10 orders,4 classes,and 2 phyla,were isolated from various tissues of Z. nitidum,of which Colletotrichum and Fusarium were the dominant genera,respectively accounting for 20% of total strains. The diversity of endophytic fungi was significantly different among roots,stems,and leaves,as manifested by the significantly higher Shannon index( H') in stems( 1. 678) than in roots( 0. 882 1) and leaves( 0. 515 4). The antimicrobial activity analysis showed that 14. 28% of endophytic fungi inhibited at least one indicator pathogen. Among them,Fusarium sp. ZN-34 and Fusarium sp. ZN-26 separately demonstrated the strongest inhibitory effect on Escherichia coli and Staphylococcus aureus. In general,Fusarium sp. ZN-26 and Phialemoniopsis plurioloculosa ZN-35 were advantageous in suppressing the two bacteria owing to the broad spectrum and strong efficacy. In summary,Z. nitidum in Guangxi boasts rich endophytic fungi with the majority showing strong antibacterial activity,which can be used as candidates for the extraction and separation of basic antibacterial substances and the development of natural antibacterial agents.

Lysophosphatidic acid (LPA), a bioactive lipid medium, plays an important role in the development and progression of ovarian cancer. Doxorubicin hydrochloride (DOX) is a first-line drug in the ovarian cancer clinical therapy, while the effect and molecular mechanism of LPA in the ovarian cancer with DOX treatment is still unclear. This study intended to explore the effect and molecular mechanism of LPA in ovarian cancer treated with DOX. SKOV3 and OVCAR-3 cells of human ovarian cancer and Chinese hamster ovary cells were treated with control, LPA (lOp-mol/L), DOX (2jjLmol/L) and LPA (10jJLmol/L) + DOX (2p,mol/L) respectively for 24 hours. The morphological changes of SKOV3 cells were observed under optical microscope and transmission electron microscope. Results showed that LPA reduced cell death and the degree of chromatin aggregation in SKOV3 cells treated with DOX; RT-qPCR showed that LPA treatment could down-regulate the mRNA levels of caspase-3 in DOX-treated SKOV3 cells (P<0. 05); Western blot showed that LPA treatment could reduce caspase-3 and cleaved caspase-3 levels treated with DOX in SKOV3, OVCAR-3 and CHO cells (P<0. 05); Flow cytometry using Annexin V/PI double staining showed that LPA could down-regulate apoptosis in SKOV3 cells treated with DOX (P<0. 05); DCFH-DA method was used to detect intracellular levels of reactive oxygen species (ROS) in SKOV3 cells. It was found that LPA reduced the intracellular ROS level treated with DOX (P<0. 05). Our preliminarily study showed the effect of LPA in the apoptosis of ovarian cancer treated with DOX, which may provide a reference for the drug therapy of ovarian cancer targeting LPA.
