This study primarily investigates the effect of Liuwei Dihuang Pills on the activation and proliferation of female germline stem cells(FGSCs) in the ovaries and cortex of mice with premature ovarian failure(POF), and how it improves ovarian function. ICR mice were randomly divided into the control group, model group, Liuwei Dihuang Pills group, Liuwei Dihuang Pills double-dose group, and estradiol valerate group. A mouse model of POF was established by intraperitoneal injection of cyclophosphamide. After successful modeling, the mice were treated with Liuwei Dihuang Pills or estradiol valerate for 28 days. Vaginal smears were prepared to observe the estrous cycle and body weight. After the last administration, mice were sacrificed and sampled. Serum levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-Müllerian hormone(AMH) were measured by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe ovarian morphology and to count follicles at all stages to evaluate ovarian function. Immunohistochemistry was used to detect the expression of mouse vasa homolog(MVH), a marker of ovarian FGSCs. Immunofluorescence staining, using co-labeling of MVH and proliferating cell nuclear antigen(PCNA), was used to detect the expression and localization of specific markers of FGSCs. Western blot was employed to assess the protein expression of MVH, octamer-binding transcription factor 4(Oct4), and PCNA in the ovaries. The results showed that compared with the control group, the model group exhibited disordered estrous cycles, decreased ovarian index, increased atretic follicles, and a reduced number of follicles at all stages. FSH and LH levels were significantly elevated, while AMH and E_2 levels were significantly reduced, indicating the success of the model. After treatment with Liuwei Dihuang Pills or estradiol valerate, hormone levels improved, the number of atretic follicles decreased, and the number of follicles at all stages increased. MVH marker protein and PCNA proliferative protein expression in ovarian tissue also increased. These results suggest that Liuwei Dihuang Pills regulate estrous cycles and hormone disorders in POF mice, promote the proliferation of FGSCs, improve follicular development in POF mice, and enhance ovarian function.

This study explored the mechanism of Xiangsha Liujunzi Decoction(XSLJZD) in the treatment of functional dyspepsia(FD) based on inositol-requiring enzyme 1(IRE1)/apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase(JNK) pathway-mediated autophagy in interstitial cells of Cajal(ICC). Forty-eight SPF-grade male SD suckling rats were randomly divided into a blank group and a modeling group, and the integrated modeling method(iodoacetamide gavage + disturbance of hunger and satiety + swimming exhaustion) was used to replicate the FD rat model. After the model replications were successfully completed, the rats were divided into a model group, high-dose, medium-dose, and low-dose groups of XSLJZD(12, 6, and 3 g·kg~(-1)·d~(-1)), and a positive drug group(mosapride of 1.35 mg·kg~(-1)·d~(-1)), and the intervention lasted for 14 days. The gastric emptying rate and intestinal propulsion rate of rats in each group were measured. The histopathological changes in the gastric sinus tissue of rats in each group were observed by hematoxylin-eosin(HE) staining. The ultrastructure of ICC was observed by transmission electron microscopy. The immunofluorescence double staining technique was used to detect the protein expression of phospho-IRE1(p-IRE1), TNF receptor associated factors 2(TRAF2), phospho-ASK1(p-ASK1), phospho-JNK(p-JNK), p62, and Beclin1 in ICC of gastric sinus tissue of rats in each group. Western blot was used to detect the related protein expression of gastric sinus tissue of rats in each group. Compared with those in the blank group, the rats in the model group showed decreased body weight, gastric emptying rate, and intestinal propulsion rate, and transmission electron microscopy revealed damage to the endoplasmic reticulum structure and increased autophagosomes in ICC. Immunofluorescence staining revealed that the ICC of gastric sinus tissue showed a significant elevation of p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins and a significant reduction of p62 protein. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. Compared with the model group, the body weight of rats in the high-dose and medium-dose groups of XSLJZD was increased, and the gastric emptying rate and intestinal propulsion rate were increased. Transmission electron microscopy observed amelioration of structural damage to the endoplasmic reticulum of ICC and reduction of autophagosomes, and the p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins in the ICC of gastric sinus tissue were significantly decreased. The p62 protein was significantly increased. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. XSLJZD can effectively treat FD, and its specific mechanism may be related to the inhibition of the expression of molecules related to the endoplasmic reticulum stress IRE1/ASK1/JNK pathway in ICC and the improvement of autophagy to promote gastric motility in ICC.

Objective To investigate the effect and mechanism of Efferocytosis Relatived LncRNA (EFRL) on homocysteine-induced atherosclerosis in macrophage efferocytosis. Methods RAW264.7 cells were cultured in vitro, and the Control group (0 μmol/L Hcy) and Hcy intervention group (100 μmol/L Hcy) were set up. After GapmeR transfection of macrophages with Hcy intervention, EFRL knockdown negative control group (Hcy combined with LNA-NC) and EFRL knockdown group (Hcy combined with LNA-EFRL) were set up. High-throughput sequencing was applied for different expression of LncRNA MSTRG. 88917.16 (EFRL), UCSC was used to analyze its conservation, CPC and CPAT were used to analyze its ability to encode proteins, and GO and KEGG were used to analyze related biological functions. The localization of LncRNA EFRL in macrophages was analyzed by nucleoplasmic separation and RNA-FISH. Quantitative real-time PCR was used to detect the expression levels of LncRNA EFRL and its target gene SPAST in Hcy-treated macrophages. The apoptosis rate of Jurkat cells induced by UV was detected by flow cytometry. In vitro efferocytosis assay combined with immunofluorescence technique was used to analyze macrophage efferocytosis. ELISA was used to detect the levels of interleukin 1β(IL-1β) and IL-18. Results The new LncRNA MSTRG.88917.16 was identified and named EFRL(Efferocytosis Relatived LncRNA). UCSC, CPC and CPAT analyses showed that LncEFRL is highly conserved and does not have the ability to encode proteins. GO and KEGG analyses suggested that LncEFRL may be involved in macrophage efferocytosis. LncRNA EFRL was localized in the nucleus of macrophages as determined by nucleoplasmic separation and RNA-FISH. In comparison to the Control group, the expression levels of LncRNA EFRL and its target gene SPAST in the Hcy group were increased. In comparison to the Control group (0 min), the apoptosis rate of the experimental group (15, 30 min) Annexin V is more than 85%. Compared with Hcy combined with LNA-NC group, Hcy combined with LNA-EFRL group had enhanced macrophage efferocytosis and reduced levels of inflammatory factors. Compared with Hcy combined with LNA-NC group, the expression level of SPAST in Hcy combined with LNA-EFRL group was decreased. Conclusion Inhibition of EFRL expression can alleviate the process of Hcy inhibiting macrophage efferocytosis, and the mechanism is related to the regulation of the downstream target gene SPAST by EFRL.

OBJECTIVE:
To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS).
METHODS:
Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed.
RESULTS:
The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×109/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months.
CONCLUSIONS
Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×109/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

5.Research Progress of the Wnt/β-catenin Signaling Pathway in the Regulation of Oxidative Stress and Its Impact on the Hematopoietic System --Review.
Journal of Experimental Hematology 2025;33(3):927-930
Excessive generation of reactive oxygen species (ROS) can lead to oxidative-antioxidative imbalance in the organism, resulting in oxidative stress. Hematopoietic stem/progenitor cells (HSPCs) exhibit high sensitivity to changes in ROS levels, and high levels of ROS can impair self-renewal capacity of HSPCs, leading to oxidative damage and even death. Wnt/β-catenin signaling pathway regulates hematopoiesis and plays an important role in determining the fate of stem cells, such as self-renewal, proliferation and differentiation of HSPCs. Studies have shown that Wnt/β-catenin signaling pathway is also closely related to oxidative stress. This article summarizes the relevant literature, and reviews the role of Wnt/β-catenin signaling pathway in oxidative stress, its impact on hematopoietic system, and the current research status of related mechanisms.

Journal of Experimental Hematology 2025;33(4):1086-1093
OBJECTIVE:
To investigate the clinical characteristics and prognosis of patients with hemophagocytic lymphohistiocytosis (HLH).
METHODS:
Clinical data of 78 patients with HLH admitted to Gansu Provincial People's Hospital from January 2014 to May 2023 were collected, and the correlation between relevant indicators and patient prognosis was analyzed.
RESULTS:
Among the 78 HLH patients, there were 48 males and 30 females, with a median age of onset of 48 (1-84) years old; 26 patients were treated with chemotherapy, 44 patients were treated with glucocorticoids, immunoglobulin or cyclosporine, 5 patients received symptomatic treatment, 1 patient received plasma exchange, and 2 patients refused treatment. By the end of the follow-up, there were 39 survivors, 35 deaths, and 4 patients lost to follow-up. There was no significant correlation between sex, ferritin, triglycerides, hemophagocytosis, bone marrow cellularity, Epstein-Barr virus (EBV) infection, SUV value of PET-CT, alanine aminotransferase (ALT), interleukin-6 (IL-6), platelet-to-lymphocyte ratio (PLR) and overall survival (OS) of the patients (P >0.05). Patients with age≥60 years, neutrophil-to-lymphocyte ratio (NLR) >0.59, red cell distribution width-to-platelet ratio (RPR) >0.30, lymphocyte-to-monocyte ratio (LMR)≤2.74, red blood cell distribution width (RDW)>16.45%, tumor-associated HLH, aspartate aminotransferase (AST)≥148 U/L, procalcitonin (PCT)≥0.66 ng/ml, neutrophils (NEU) <2×109/L, fibrinogen (FIB)<1.85 g/L, lactate dehydrogenase (LDH)≥1 740 U/L, hemoglobin (Hb)<85 g/L, platelet (PLT)<57×109/L had significantly shorter OS, with statistical significance (P < 0.05). Multivariate analysis showed that LMR≤2.74, RDW>16.45%, LDH≥1 740 U/L, and NEU<2×109/L were independent risk factors affecting OS in HLH patients (P < 0.05).
CONCLUSION
Some blood-based inflammatory markers are significantly associated with OS in patients with HLH. NLR, RPR, LMR, RDW and PCT can be used to assess the prognosis of HLH patients, and RDW and LMR are independent factors affecting OS of HLH patients, which provide greater predictive value for prognosis. Hypercellular bone marrow in HLH patients may indicate a poor prognosis.

ObjectiveTo explore the protective effects of Dahuang Tangluo pills on early diabetic kidkdey disease (DKD) in db/db mice. MethodEight db/m mice were selected as the control group. Forty male db/db mice were selected and blood samples were collected via tail vein to measure fasting blood glucose (FBG). Mice with FBG ≥ 16.7 mmol·L-1, increased urine output, and persistent albuminuria were considered successful in model establishment. After successful modeling, they were randomly divided into a model group, a dapagliflozin group (1.5 mg·kg-1·d-1), and high, medium, and low dose groups of Dahuang Tangluo pills (3.6, 1.8, 0.9 g·kg-1·d-1, respectively), with eight mice in each group. All medication groups were administered orally, while the control and model groups were given an equal amount of distilled water by gavage daily. After continuous administration for 10 weeks, the survival status of the mice was observed, and their body weight, FBG, and kidney function-related indicators were measured. Inflammatory indicators in renal tissues were determined by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining, Masson staining, and electron microscopy were used to observe the pathological changes in renal tissues in each group. Immunofluorescence was employed to examine the expression of advanced glycation end products (AGEs) and receptors for advanced glycation end products (RAGE) proteins. Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot were utilized to detect the gene and protein expression levels of AGEs, RAGE, inhibitor of nuclear factor-κB (NF-κB) kinase (IKK), and NF-κB in the renal tissues of mice in each group. ResultCompared with control group, the model group showed a significant increase in body weight, FBG, serum creatinine (SCr), urinary microalbumin/urine creatinine ratio (ACR), total cholesterol (TC), and triglycerides (TG) (P<0.05). The levels of intercellular adhesion molecule-1 (ICAM-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) in renal tissues were significantly elevated (P<0.05). Renal histopathological staining and electron microscopy revealed loose arrangement, gaps, structural disarray, mesangial proliferation, and significant fibrosis in renal tissues. Real-time PCR results showed a significant increase in the expression of RAGE, IKK, and NF-κB genes in renal tissues (P<0.05). Immunofluorescence results demonstrated a significant increase in the expression of AGEs and RAGE proteins in renal tissues (P<0.05). Western blot results showed a significant increase in the expression of AGEs, RAGE, IKK, and NF-κB proteins in renal tissues (P<0.05). After drug intervention, compared with model group, the dapagliflozin group and the high-dose Dahuang Tangluo pills group showed significant reductions in body weight, FBG, SCr, and ACR (P<0.05), and a significant decrease in TC in mouse serum (P<0.05), while the high-dose Dahuang Tangluo pills group showed a significant decrease in TG in mouse serum (P<0.05). All treatment groups showed a significant reduction in ICAM-1, IL-6, and TNF-α in renal tissues (P<0.05). Renal histopathological staining and electron microscopy showed improved kidney injury, decreased collagen fiber deposition, and reduced mesangial proliferation in all treatment groups. Real-time PCR results showed a significant decrease in the expression of RAGE, IKK, and NF-κB genes in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups (P<0.05). Immunofluorescence results demonstrated a significant decrease in the expression of AGEs and RAGE proteins in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups (P<0.05). Western blot results showed a significant decrease in the expression of AGEs, RAGE, IKK, and NF-κB proteins in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups (P<0.05). ConclusionDahuang Tangluo pills can improve the pathological structure of the kidneys and reduce renal inflammation in DKD mice, possibly through inhibiting the AGEs/RAGE/IKK/NF-κB pathway.

ObjectiveTo discuss the effect of modified Gegen Qinliantang (MGQT) on blood glucose and lipids and Takeda G protein-coupled receptor 5 (TGR5)-related pathways in pancreatic tissue of obese type 2 diabetes mellitus (T2DM) mice. MethodA total of 10 male specific pathogen free (SPF) m/m mice (7 weeks old) and 50 male SPF (7 weeks old) were adaptively fed for one week in SPF laboratory. The m/m mice were included in the blank group. T2DM was induce d in the 50 db/db mice. The model mice were randomized into the model group, metformin group (0.2 g·kg-1), high-dose, medium-dose, and low-dose (31.9, 19.1, 6.4 g·kg-1) MGQT groups, with 10 in each group, and the drug dose was10 mL·kg-1. The model group and the blank group received distilled water of the same volume. The administration lasted 12 weeks (once/day). Fasting blood glucose (FBG) was detected regularly. After 12 weeks of administration, serum levels of glycated serum protein (GSP), serum glucose (GLU), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. Pathological changes in the pancreatic tissue were based on hematoxylin-eosin (HE) staining. Western blot was used to determine the protein expression of TGR5, protein kinase A (PKA), phosphorylated (p)-PKA, cyclic-AMP response element binding protein (CREB), p-CREB, proprotein convertase 1/3 (PC1/3), and glucagon-like peptide-1 (GLP-1) in pancreatic tissues. The level of cyclic adenosine monophosphate (cAMP) in pancreatic tissue was determined by enzyme-linked immunosorbent assay (ELISA). ResultCompared with the blank group, the model group had pathological changes in pancreatic tissue, high levels of FBG, GSP, GLU, TC, TG, and LDL-C (P<0.01), low level of HDL-C (P<0.05), low protein expression of TGR5, p-PKA (Thr197)/PKA, p-CREB (Ser133)/CREB, PC1/3, and GLP-1 in pancreatic tissue (P<0.01), and low content of cAMP in the pancreas (P<0.01). Pancreatic tissue lesion in the treatment groups were milder than that in the model group. Both the high-dose MGQT and metformin can reduce the levels of FBG, GSP, GLU, TC, TG, and LDL-C in db/db mice (P<0.05, P<0.01) and increase the level of HDL-C (P<0.01). Except the GLP-1 protein in the medium-dose MGQT group, the protein expression of TGR5, p-PKA (Thr197)/PKA, p-CREB (Ser133)/CREB, PC1/3, and GLP-1 in the high-dose and medium-dose MGQT groups and the metformin group increased compared with that in the model group (P<0.05, P<0.01). The content of cAMP in the pancreatic tissue of the high-dose and medium-dose MGQT groups and the metformin group was raised compared with that in model group (P<0.05, P<0.01). ConclusionMGQT can improve the glucose homeostasis in db/db mice with T2DM by regulating TGR5/cAMP/GLP-1 signaling pathway-related protein expression.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

OBJECTIVE To establish a quantitative analysis of multi-components by single marker (QAMS) method based on a variety of internal reference substances for the content determination of 6 components in Jinlian qingre granules, such as mangiferin, 2″-O-β-L-galactopyranosylorientin, orientin, veratric acid, vitexin, harpagoside. METHODS The determination was performed on Agilent Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 1 mL/min. The column temperature was 30 ℃, and the detection wavelength was set at 270 nm. Taking orientin, vitexin and 2″-O-β-L-galactopyranosylorientin as internal references, the relative correction factors (RCF) of the other 5 components to be determined and internal substances were determined by QAMS. The contents of 6 components in 21 batches of Jinlian qingre granules were calculated and then compared with the results of the external standard method. RESULTS The contents of mangiferin, 2″-O-β-L-galactopyranosylorientin, orientin, veratric acid, vitexin and harpagoside in 21 batches of samples were determined by QAMS in the range of 0.234-0.516, 1.804-2.270, 2.143-2.606, 0.190-0.223, 0.594-0.782, 0.080-0.152 mg/g; the contents of them determined by external standard method were 0.235-0.523, 1.798-2.265, 2.137-2.599, 0.190-0.224, 0.597-0.786, 0.077-0.151 mg/g, respectively. The percentage difference between the results measured by the two methods should not exceed 4.00%. CONCLUSIONS QAMS has been constructed for the simultaneous determination of 6 components in Jinlian qingre granules based on a variety of internal reference substances. The results obtained by this method are not significantly different from those obtained by the external standard method, and can be used for the quality control of Jinlian qingre granules.
