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.

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.

The levels of CGRPαin serum and placental tissues of pregnant women were deter- mined by ELISA . The rats pregnant normally. A hypotension rat model was established by intragastric administra- tion of risserpine . 50 rats were randomly divided into control group , model group , pregnancy group , model + preg- nancy group , model + pregnancy + phenylephrine group , with 10 rats in each group . Body weight of the rats was continuously monitored during the 2nd to 6th week of risserpine administration . Systolic blood pressure was meas- ured at the end of the 6th induction week . And the peripheral blood sample and placental tissues were collected and the levels of CGRPαwere determined . Results : The detection of CGRPαlevels in the pregnant women serum and placental tissues showed that compared with Anesthesia-0 group , CGRPαlevels in Anesthesia-1-4 groups serum were higher (P < 0. 05) . Compared with Anesthesia-3 group , serum CGRPαlevels in Anesthesia-4 group were higher (P < 0. 05) . Compared with Anesthesia-2 group , CGRPαlevels in Anesthesia-4 group serum were higher (P < 0. 05) . Compared with Anesthesia-0 group , tissues CGRPαlevels in Anesthesia-4 group were higher (P < 0. 05) . Compared with Anesthesia-3 group , CGRPαlevels in Anesthesia-4 group tissues were higher (P < 0. 05) . Compared with Anesthesia-2 group , CGRPαlevels in Anesthesia-4 group tissues were higher ( P < 0. 05) . From the 2nd to 6th week of hypotension modeling induction , compared with pregnancy group , body weight decreased in the model + pregnancy group and the model + pregnancy + phenylephrine group (P < 0. 05) . There was no signifi- cant difference in baseline systolic blood pressure among all groups (P > 0. 05) . At the end of the 6th week , com- pared with pregnancy group , systolic blood pressure decreased in model + pregnancy group and model + pregnancy + phenylephrine group(P < 0. 05) ; the levels of CGRPαin serum and placental tissues increased ( P < 0. 05) . Compared with model + pregnancy group , systolic blood pressure increased in model + pregnancy + phenylephrine group (P < 0. 05) . Conclusion The poor response of pregnant women with hypotension during caesarean section under intraspinal anesthesia to the treatment of phenylephrine may be related to the increased levels of CGRPαin placenta and peripheral blood .

BackgroundSevere mental disorders are characterized by high recurrence rate， high disability rate， high rates of harmful incidents， and low treatment-seeking rate， with affected patients demonstrating increased frequencies of dangerous behaviors. Ningxia Hui Autonomous Region has implemented community management for patients with severe mental disorders across the region since 2004， while the current status and regional characteristics of the managed patients remain unclear. ObjectiveTo analyze the current status of management and treatment of patients with severe mental disorders in Ningxia Hui Autonomous Region， and to explore their regional distribution characteristics， so as to provide references for optimizing regional prevention and control strategies. MethodsPatients with severe mental disorders diagnosed and registered in the Severe Mental Disorder Management Information Platform of Ningxia Hui Autonomous Region from August 1， 2011 to December 31， 2021 were selected. Patients' basic information， management indicators， and treatment metrics were extracted from the platform， followed by descriptive statistical analysis of the corresponding data. ResultsAs of December 31， 2021， the permanent resident population of Ningxia Hui Autonomous Region was 6 946 540， with 29 787 registered patients with severe mental disorders. The majority of the patients were female （50.25%）， aged 18-59 years （79.01%）， with educational level of junior high school or below （84.63%）， married （52.87%）， farmers （56.01%）， and diagnosed with schizophrenia （55.91%）， while ethnic minority patients accounted for a relatively high proportion （31.35%）. In 2021， the reported prevalence rate of severe mental disorders in Ningxia Hui Autonomous Region was 0.43%， with standardized management and regular medication adherence rates at 90.39% and 66.34%， respectively. The standardized management rate in 8 counties/districts （36.36%） was lower than the average level of Ningxia Hui Autonomous Region， while 10 counties/districts （45.45%） showed below-average medication adherence rates， of which 6 counties/districts（60.00%） were located in the south-central region. ConclusionPatients with severe mental disorders in Ningxia Hui Autonomous Region are predominantly young and middle-aged adults with low level of education， and those in the central-southern region demonstrate lower medication adherence. ［Funded by Key Research and Development Program Project of Ningxia Hui Autonomous Region （number， 2023BEG02029）］

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.

Objective::To use fetal heart quantification ( fetal HQ) technology to compare the coarctation of the aorta (CoA) and normal fetal heart structure and systolic function and to assess whether there are abnormalities in the fetal heart structure and systolic function associated with CoA. Methods::This prospective cohort study was conducted from May 2020 to December 2022 and involved 18-40-week-old singleton pregnancies and 30 fetuses diagnosed with CoA using fetal echocardiography at the General Hospital of Ningxia Medical University and Peking University First Hospital Ningxia Women’s and Children’s Hospital, China. The control group contained 60 normal fetuses. The following parameters were recorded and analyzed statistically: four-chamber view (4CV) end-diastolic long diameter, 4CV epicardial-contralateral epicardial transverse maximum diameter, 4CV global sphericity index (GSI), left ventricular (LV) and right ventricular (RV) 24-segment end-diastolic diameter (EDD), 24-segment sphericity index (SI), LV-fractional area change (LV-FAC), LV-longitudinal strain (LV-LS), RV-fractional area change (RV-FAC), RV-longitudinal strain (RV-LS), and LV and RV 24-segment transverse fractional shortening (FS). Measurement data were compared between the two groups using an independent sample t test, with P < 0.05 indicating statistically significant differences. Moreover, the correlation between gestational age and GSI, LV-FAC, LV-LS, RV-FAC, and RV-LS was assessed. Results::Within and between observer comparisons of the parameters associated with major cardiac function revealed an intragroup correlation coefficient of >0.9, indicating high consistency, and a coefficient of variable of <1 %, indicating low variability. Correlation analysis revealed no obvious correlation between gestational age and GSI, LV-FAC, LV-LS, RV-FAC, and RV-LS. A comparison of the four-chamber morphological structural parameters of the hearts in the two groups revealed that when compared with the control group, the 4CV end-diastolic long diameter was shortened in fetuses in the CoA group and the epicardial-contralateral epicardial transverse maximum diameter was wider, while the GSI was lower ( P < 0.05). A comparison of the LV and RV morphological structure parameters between the two groups revealed that when compared with the control group, the LV’s 24-segment EDD was smaller in the CoA group, the RV’s 24-segment EDD was greater in the control group, the SI of the LV’s segments 16-24 was greater than in the control group, and the SI of the RV’s segments 7-24 was less than in the control group (all P < 0.05). When compared with fetuses in the control group, the LV’s segments 16-24 were greater in the CoA group, whereas the RV’s segment 6-24 was smaller ( P < 0.05). When compared with the control group, LV-FAC, RV-FAC, and LS were lower in the CoA group ( P < 0.05). The FS of the LV segments 1-24 and the FS of the RV segments 1-16 were smaller in the CoA group than in the normal group ( P < 0.05). Conclusion::Fetal HQ, a new simple technique that offers rapid analysis and high repeatability, can quantitatively evaluate structural and systolic function changes in fetuses with CoA.
