OBJECTIVE To investigate the effects of medicated serum of Siwutang on autophagy of ovarian granulosa cells (KGN cells) in polycystic ovarian syndrome (PCOS) and its underlying mechanism. METHODS Blank serum and different- concentration medicated serum of Siwutang were prepared by intragastric administration of normal saline and different doses of Siwutang [0.52, 1.04, 2.08 g/(kg·d)] in 3-month-old female SD rats. After screening the intervention concentration of Siwutang medicated serum, KGN cells were divided into control group (without any treatment), dehydroepiandrosterone (DHEA) group (treated with 50 μmol/L DHEA for 48 h), blank serum group (treated with 50 μmol/L DHEA for 48 h and with 10% blank serum for 72 h) and medium-concentration of Siwutang medicated serum group (treated with 50 μmol/L DHEA for 48 h and with 10% medium-concentration Siwutang medicated serum for 72 h). The number of autophagosomes was observed in each group, and protein expressions of pathway-related proteins [fructose-1, 6-bisphosphatase 1 (FBP1),mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR)], autophagy-related proteins [p62, microtubule-associated protein 1 light chain 3 (LC3)] and mRNA expression of FBP1 were also detected. The (transfected) cells were further divided into Siwutang group (treated with 10% medium dose of Siwutang medicated serum for 72 h after 48 h intervention with 50 μmol/L DHEA), Siwutang+si-NC group [negative control small interfering RNA (siRNA) transfected cells treated with 50 μmol/L DHEA for 48 h, and then with 10% medium-concentration of Siwutang medicated serum for 72 h] and Siwutang+si-FBP1 group (FBP1 siRNA transfected cells treated with 50 μmol/L DHEA for 48 h, and then with 10% medium-concentration Siwutang medicated serum for 72 h). The effects of knocking down FBP1 on the above-mentioned effects of Siwutang were detected. RESULTS Compared with control group, DHEA group exhibited an increase in the number of autophagosomes, an elevated LC3-Ⅱ/LC3-Ⅰ and p-mTOR/mTOR, as well as increases in protein and mRNA expressions of FBP1, and decreased protein expression of p62 (P<0.05). Compared to both DHEA group and blank serum group, the medium-concentration of Siwutang medicated serum group showed a decrease in the number of autophagosomes, a decrease in LC3-Ⅱ/LC3-Ⅰ, and increases in p-mTOR/mTOR, protein expression of p62, protein and mRNA expressions of FBP1 (P<0.05). After knocking down FBP1, compared with Siwutang+si-NC group, Siwutang+si-FBP1 group showed a significant decrease in cell viability, protein expression of p62 , protein and mRNA expressions of FBP1 as well as p-mTOR/mTOR, and an increase in LC3-Ⅱ/LC3-Ⅰ (P<0.05). CONCLUSIONS Siwutang can promote the phosphorylation of mTOR protein by up- regulating the protein and mRNA expressions of FBP1 in KGN cells, thus inhibiting autophagy of KGN cells.

[Objective] To explore the influencing factors of quality monitoring index on the nucleic acid pooling detection mode and continuously improve the detection quality of nucleic acid laboratory. [Methods] The quality monitoring indicators (NAT reactive rate, NAT resolution reactive rate, NAT invalid batch rate, NAT invalid result rate, equipment failure rate) and causes of invalidity in our laboratory from January 1, 2020 to December 31, 2022 were retrospectively analyzed. The quality monitoring indicators of the laboratory during 2020 to 2022 were compared longitudinally. The quality monitoring indicators of the laboratory in 2022 were compared horizontally with the overall level in Shandong for the same period to find the differences. [Results] From 2020 to 2022, a total of 218 686 samples were detected, the NAT reactive rate was 0.15‰ (32 samples in total), the resolution reactive rate was 39.02%, the invalid batch rate was 1.06%, the invalid result rate was 1.18%, and the equipment failure rate was 3.58%. There were no differences in the NAT reactive rate, NAT resolution reactive rate and NAT invalid batch rate among different years (P>0.05), but there were differences in the invalid result rate (P<0.05). Equipment failure was the main cause of invalid results (56.53%). Compared with other laboratories in Shandong, there were differences in the NAT reactive rate and invalid result rate (P<0.05). There were differences in the reaction rate, resolution rate and invalid result rate among different reagents (P<0.05). Compared with other two laboratories using the same manufacturer's reagent, there were differences in the reactive rate and invalid result rate (P<0.05), but no difference in the resolution rate and invalid batch rate (P>0.05). [Conclusion] Establishing quality indexes for process control and regular analysis can timely detect potential risks in laboratory operation. The use of quality indicators to implement self-comparison and inter-laboratory comparison can help the laboratory systematically and scientifically evaluate its own operating status and formulate corresponding quality management strategies, thereby improving the laboratory's testing capacity and ensure the safety of blood use.

Chronic atrophic gastritis (CAG), a common digestive system disease, has an unclear pathogenesis. Currently, it is mostly believed to be related to Helicobacter pylori (Hp) infection, immune factors, dietary factors, bile reflux, long-term use of antibiotics and anti-inflammatory drugs, and other factors. Ferroptosis is a regulated cell death mechanism that is iron-dependent and characterized by disruption of iron metabolism and accumulation of lipid peroxides. More and more studies have found that ferroptosis is closely related to the onset of CAG. Professor LI Diangui, a master of traditional Chinese medicine, first proposed the turbid toxin theory, which holds that spleen deficiency and turbid toxin is the main pathogenic mechanism of CAG. Abnormal iron metabolism regulation is a prerequisite for the accumulation of turbid toxin in CAG, and ferroptosis is in accordance with the pathogenic mechanism (spleen deficiency and turbid toxin) of CAG. This article explores the pathological mechanism of spleen deficiency and turbid toxin in CAG from the perspectives of iron metabolism, oxidative stress, and lipid peroxidation, providing theoretical support of traditional Chinese medicine for the modern research on CAG. It enriches the modern scientific connotation of the turbid toxicity theory and provides new ideas and breakthrough points for the clinical treatment of CAG.

AIM: To investigate the specific molecular mechanism of Yinqiao Powder in affecting macrophage polarization in herpes simplex keratitis(HSK)through the cyclic GMP-AMP synthetase(cGAS)-stimulator of interferon genes(STING)-interferon regulatory factor 3(IRF3)molecular pathway.METHODS:Human corneal epithelial cells(HCE-T)were divided into control, HSK, and HSK + Yinqiao Powder groups. M0 macrophages were grouped as Ctrl, HSV-1, HSV-1+oe-cGAS, HSV-1+Yinqiao Powder, and HSV-1+oe-cGAS+Yinqiao Powder. Conditional medium(CM)from each group of M0 macrophages was collected to intervene in HCE-T cells and divided into Ctrl-CM, HSV-1-CM, HSV-1+oe-cGAS-CM, and HSV-1+Yinqiao Powder-CM groups. Cell viability was detected by MTT assay, and apoptosis was detected by TUNEL assay. ELISA was used to detect the concentrations of Arg-1 and iNOS in cell supernatants, and Western blotting was used to detect the relative protein expressions of cGAS, STING, and IRF3. Balb/c mice were divided into control, model, and drug groups. The model and drug groups were inoculated with HSV-1 on the cornea of Balb/c mice using the corneal scratch method to construct an HSK mouse model, and the drug group was treated with Yinqiao Powder. The incidence and mortality of the three groups were compared on days 1, 3, 5, 7, and 14 after modeling.RESULTS:Compared with the control group, the HCE-T cell viability in the HSK group was decreased but apoptosis was increased, which was reversed by Yinqiao Powder intervention. Compared with the Ctrl group, the Arg-1 concentration in the cell supernatant of the HSV-1 group was decreased, the iNOS concentration was increased, and the protein expressions of cGAS, STING, and IRF3 were decreased. Compared with the HSV-1 group, the Arg-1 concentration was increased, the iNOS concentration was decreased, and the protein expressions of cGAS, STING, and IRF3 were enhanced in the HSV-1+oe-cGAS group and the HSV-1+Yinqiao Powder group, and the same results were obtained in the HSV-1+oe-cGAS+Yinqiao Powder group. Compared with the Ctrl-CM group, the HCE-T cell viability was decreased and apoptosis was increased in the HSV-1-CM group, which was reversed by overexpressing cGAS in macrophages or intervening with Yinqiao Powder. In vivo experiments found that Yinqiao Powder intervention could improve the pathological progression of keratitis.CONCLUSION:Yinqiao Powder inhibits M1 polarization of macrophages through the cGAS-STING-IRF3 molecular pathway, thereby delaying the progression of HSK.

Objective To analyze the changes of liver and kidney function, blood glucose and lipid metabolism at different follow-up time points of different treatment regimens, and to provide reference for clinical optimization and adjustment of medication in HIV/AIDS patients. Methods The changes of liver and kidney function, blood glucose and lipid metabolism at seven follow-up time points were analyzed retrospectively. The baseline blood collection time of HIV /AIDS patients was set as the starting point, and the final follow-up time was set as the end point. The seven follow-up points were 0, 3, 6, 9, 12, 18 and 24 months respectively. Results There were statistically significant differences in the distribution of sex, age, education, marital status, WHO staging, infection route, and baseline CD4+T lymphocyte count among 605 enrolled patients based on different treatment regimens. Liver function: The level of T-Bil in group E was higher than that of baseline at 9M, 12M, 18M and 24M after treatment (P<0.01); In group F, the level of T-Bil was higher than that of baseline at 9M after treatment (P=0.001); The levels of ALT in group C at the six follow-up points after treatment were higher than the baseline (P<0.001); The level of AST in group C was higher than that of baseline after 3M and 6M treatment (P<0.05). Renal function: The level of UREA in group C was higher than that in baseline after 6M treatment (P=0.007); The level of UREA in group F was higher than that in the baseline after 12M treatment (P<0.001); The level of UA in group F was higher than that of baseline after 3M, 6M and 12M treatment (P<0.05). Blood lipid and blood glucose: The levels of Glu at some follow-up points after ART treatment in group A and group C were higher than that at baseline (P<0.05); The levels of TG at some follow-up points in group A, group E and group F after ART treatment were higher than those at baseline (P<0.05); The levels of TC at some follow-up points in group A, group B, group C, group E and group F after ART treatment were all higher than the baseline (P<0.05). Conclusion Regular monitoring of changes in laboratory indicators of different treatment regimens during ART is of great importance to the prognosis of patients. Different laboratory indicators should be monitored according to different treatment regimens to effectively prevent adverse reactions caused by different treatment regimens.
