Establishment of abdominal aortocaval fistula in adenine-induced renal failure rats / 中华肾脏病杂志

Objective:To explore the construction of abdominal aortocaval fistula (ACF) model in adenine-induced renal failure rats, and to provide a suitable animal model for subsequent mechanism and intervention researches.Methods:Adult female Sprague-Dawley rats (250-300 g) were fed with 0.75% adenine diet (renal failure group, n=60) and the same diet without adenine (control group, n=10) for 4 weeks, and the rats were randomly grouped by block randomization method with a ratio of 6∶1. Thirty rats in the renal failure group were randomly selected by block randomization method at a ratio of 1∶1 to undergo laparotomies to establish ACF models (renal failure+ACF group). The serum creatinine, blood urea nitrogen detection and Masson staining were used to evaluate the establishment of renal failure model. Small animal ultrasound imaging system was applied to verify the successful construction of the ACF model. After 6 weeks of ACF observation, blood samples were collected from the heart of rats, and ACF-vascular tissues were collected for pathological study (HE staining). Results:At 4 weeks of feeding, compared with the control group, serum creatinine [(63.8±23.5) μmol/L vs. (33.0±3.8) μmol/L, Z=3.651, P<0.001] and blood urea nitrogen [(13.1±6.9) mmol/L vs. (5.3±0.6) mmol/L, Z=3.254, P=0.001] in the renal failure group were both higher. Masson staining showed renal tubulointerstitial inflammatory cell infiltration, renal tubular epithelial cell atrophy, interstitial fibrosis and vascular injury. Five rats sacrificed after ACF surgeries, and the survival rate was 83.3%. Doppler ultrasound showed turbulent blood flow of arterial to venous shunt at the anastomosis of open ACF (23/25) in the renal failure+ACF group. HE staining showed typical eccentric neointimal hyperplasia in the outflow tract of ACF vein in the renal failure+ACF group. Conclusions:The adenine-induced ACF rat model is successfully constructed, and ACF shows typical eccentric neointimal hyperplasia. The ACF construction would provide a reliable animal model to study the mechanism and intervention of neointimal hyperplasia for autologous arteriovenous fistula.

Pachymaran regulates pyroptosis of liver cancer cells via SQLE/NLRP3/GSDMD signaling pathway / 中国病理生理杂志

AIM:Using bioinformatics analysis and experiment validation to explore the differential expres-sion genes related to abnormal lipid metabolism in hepatocellular carcinoma(HCC)and the molecular mechanism of pachymaran affecting pyroptosis through squalene epoxidase(SQLE)/nucleotide-binding oligomerization domain-like re-ceptor protein 3(NLRP3)/gasdermin D(GSDMD)signaling pathway.METHODS:(1)The GEO,GSEA,DAVID,STRING and GEPIA databases were employed to screen abnormal lipid metabolism-related differentially expressed genes in HCC.(2)The tumor tissues from HCC patients(n=9)were collected to verify the differential expression of SQLE.(3)The inhibitory effect of pachymaran on the viability of human HCC cell line HepG2 was measured by CCK-8 assay.(4)The HepG2 cells were divided into control group and pachymaran(800 mg/L)group.The cell migration was analyzed by wound-healing assay,and RT-qPCR was used to measure SQLE mRNA expression.(5)The HepG2 cells with overexpres-sion of SQLE(OE-SQLE)were divided into 5 groups as follows:control group,overexpression negative control(OE-NC)group,OE-SQLE group,OE-NC+pachymaran group,and OE-SQLE+pachymaran group.The mRNA and protein expres-sion levels of SQLE and pyroptosis-related factors were determined by RT-qPCR and Western blot.Colorimetric method and ELISA were used to measure lactate dehydrogenase(LDH),interleukin-1β(IL-1β)and IL-18 levels.The necrosis of HepG2 cells was analyzed by flow cytometry.RESULTS:The SQLE gene was screened through bioinformatics analysis,and its mRNA expression was significantly increased in tumor tissues from HCC patients(P＜0.01).In cell experiments,treatment with 800 mg/L pachymaran for 48 h had a significant inhibitory effect on HepG2 cell viability,and the expres-sion of SQLE mRNA was reduced(P＜0.01).After overexpression of SQLE,the mRNA and protein levels of pyroptosis-re-lated factors,necrotic rate,and LDH,IL-1β and IL-18 levels were significantly decreased(P＜0.05).After treatment with pachymaran,the above indicators were significantly increased(P＜0.05).CONCLUSION:The SQLE is abnormal-ly highly expressed in HCC,and pachymaran can affect the growth of HCC cells by activating the NLRP3/GSDMD pyropto-sis pathway through SQLE.

Treatment of Liver Fibrosis after Hepatitis B with TCM Combined with NAs Evaluated by Noninvasive Diagnostic Methods: A Retrospective Study.

Objective. Chronic hepatitis B liver fibrosis is an important intermediate link in the development of liver cirrhosis. A retrospective cohort study was conducted in Longhua Hospital affiliated to the Shanghai University of Traditional Chinese Medicine in order to prove whether integrated traditional Chinese and Western medicine could improve the incidence of CHB complications and clinical prognosis. There are 130 patients with hepatitis B liver fibrosis (being treated from 2011-2021) included in the study, and the patients were divided into 64 TCM users (NAs combined with TCM) and 66 TCM nonusers (NAs antiviral therapy). The serum noninvasive diagnostic model (APRI, FIB-4) and LSM value were used to classify the stages of fibrosis. The results showed that the LSM value was decreased significantly in TCM users compared with TCM nonusers (40.63% versus 28.79%). Indicators of FIB-4 and APRI of TCM users have improved significantly compared with that of TCM nonusers (32.81% versus 10.61% and 35.94% versus 24.24%). The AST, TBIL, and HBsAg levels in TCM users were lower than those in TCM nonusers, and the HBsAg level was inversely correlated with the CD3+, CD4+, and CD8+ in TCM users. The PLT and spleen thickness of TCM users also were improved considerably. The incidence rate of end-point events (decompensated cirrhosis/liver cancer) in TCM nonusers was higher than that of TCM users (16.67% versus 1.56%). The long course of the disease and a family history of hepatitis B were the risk factors for disease progression, and long-term oral administration of TCM was the protective factor. As a result, the serum noninvasive fibrosis index and imaging parameters in TCM users were lower than those of TCM nonusers. Patients in the treatment of NAs combined with TCM had better prognoses such as a lower HBsAg level, a more stable lymphocyte function, and a lower incidence of end-point events. The present findings suggest the effect of TCM combined with NAs in the treatment of chronic hepatitis B liver fibrosis is better than that of single drug treatment.

Tumor-associated macrophages-derived exo-let-7a promotes osteosarcoma metastasis via targeting C15orf41 in osteosarcoma.

BACKGROUND: Osteosarcoma (OS) immune environment is complexed and the immune factors-related to OS progression need to be explored. Tumor-associated macrophages (TAMs) are regarded as immune suppressive and tumor-promoting cells. However, the underlying mechanisms through which TAMs function are still fragmentary. Here, we aim to explore the underlying mechanisms by which TAMs regulate OS progression. METHODS: TAMs from OS tissues were isolated by flow cytometry. Exosomes derived from TAMs were separated using ultracentrifugation and western blotting. Transmission electron microscopy (TEM), and flow cytometry were constructed to characterize TAMs-derived exosomes. Additionally, the differential MicroRNAs (miRNAs) and genes were detected through RNA sequencing, and further validated using real-time PCR (RT-PCR). OS cell metastasis ability was assessed using transwell invasion and scratch wound healing assays. MiRNAs mimic and lentiviral vectors were utilized to explore the effects on OS progression. RESULTS: Exosome secreted by TAMs accelerated the OS metastasis. Let-7a level was upregulated in TAMs derived exosomes, which downregulated C15orf41 by targeting 3'-untranslated region (UTR). Furthermore, overexpressing let-7a enhanced invasion and migration by blocking the transcription of C15orf41. In consistent, up-regulating let-7a promoted OS progression and made the prognosis to be worse, which can be reversed by C15orf41 overexpression. CONCLUSION: This study highlighted the critical role of TAMs-derived exosomes in OS progression and explored the potential value of the let-7a/C15orf41 axis as an indicator or target for OS.

Effectiveness of a mHealth intervention on hypertension control in a low-resource rural setting: A randomized clinical trial.

Background: Despite the increasing popularity of mHealth, little evidence indicates that they can improve health outcomes. Mobile health interventions (mHealth) have been shown as an attractive approach for health-care systems with limited resources. To determine whether mHealth would reduce blood pressure, promote weight loss, and improve hypertension compliance, self-efficacy and life quality in individuals with hypertension living in low-resource rural settings in Hubei, China. Methods: In this parallel-group, randomized controlled trial, we recruited individuals from health-care centers, home visits, and community centers in low-resource rural settings in Hubei, China. Of 200 participants who were screened, 148 completed consent, met inclusion criteria, and were randomly assigned in a ratio of 1:1 to control or intervention. Intervention group participants were instructed to use the Monitoring Wearable Device and download a Smartphone Application, which includes reminder alerts, adherence reports, medical instruction and optional family support. Changes in the index of Cardiovascular health risk factors from baseline to end of follow-up. Secondary outcomes were change in hypertension compliance, self-efficacy and life quality at 12 weeks. Results: Participants (n = 134; 66 in the intervention group and 68 controls) had a mean age of 61.73 years, 61.94% were male. After 12 weeks, the mean (SD) systolic blood pressure decreased by 8.52 (19.73) mm Hg in the intervention group and by 1.25 (12.47) mm Hg in the control group (between-group difference, -7.265 mm Hg; 95% CI, -12.89 to -1.64 mm Hg; P = 0.012), While, there was no difference in the change in diastolic blood pressure between the two groups (between-group difference, -0.41 mm Hg; 95% CI, -3.56 to 2.74 mm Hg; P = 0.797). After 12 weeks of follow-up, the mean (SD) hypertension compliance increased by 7.35 (7.31) in the intervention group and by 3.01 (4.92) in the control group (between-group difference, 4.334; 95% CI, 2.21 to -6.46; P < 0.01), the mean (SD) hypertension compliance increased by 12.89 (11.95) in the intervention group and by 5.43 (10.54) in the control group (between-group difference, 7.47; 95% CI, 3.62 to 11.31; P < 0.01), the mean (SD) physical health increased by 12.21 (10.77) in the intervention group and by 1.54 (7.18) in the control group (between-group difference, 10.66; 95% CI, 7.54-13.78; P < 0.01), the mean (SD) mental health increased by 13.17 (9.25) in the intervention group and by 2.55 (5.99) in the control group (between-group difference, 10.93; 95% CI, 7.74 to 14.12; P < 0.01). Conclusions: Among participants with uncontrolled hypertension, individuals randomized to use a monitoring wearable device with a smartphone application had a significant improvement in self-reported hypertension compliance, self-efficacy, life quality, weight loss and diastolic blood pressure, but no change in systolic blood pressure compared with controls.

Research progress of sphingosine kinase and sphingosine-1-phosphate (S1P) /S1P receptor signaling in tumor microenvironment / 药学学报

Sphingosine kinase (SphK), sphingosine-1-phosphate (S1P) and S1P receptor (S1PR) are involved in the tumor biological processes such as tumor cell proliferation and migration, and play an important role in the development of cancer. In recent years, researchers have increasingly focused on the interaction between cancer cells and the tumor microenvironment. The tumor microenvironment is genetically stable and can be induced to an antitumor phenotype, which has significant therapeutic advantages. Studies have shown that SphK/S1P/S1PR can regulate multiple aspects of the tumor microenvironment. This review summarizes the effects of SphK and S1P/S1PR signaling on the tumor microenvironment from four perspectives: tumor immune microenvironment, cancer associated fibroblasts, tumor angiogenesis and tumor hypoxic microenvironment, and also outlines potential drug research related to these signal molecules, aiming to elucidate the role of SphK/S1P/S1PR in tumor occurrence and development and provide new ideas for the research of anti-tumor drugs.

Application of meridian and acupoint diagnosis of three yin meridians of foot in the treatment for gynecological diseases with acupuncture and moxibustion / 中国针灸

With three representative types of gynecological diseases (dysmenorrhea, pelvic inflammation, polycystic ovary syndrome) as examples, the application methods of meridian and acupoint diagnosis for gynecological diseases treated with acupuncture and moxibustion are discussed. During clinical diagnosis and treatment, it is recommended to examine the patient's leg segment along the three yin meridians of foot, aiming to explore the positive reactions of the meridians and acupoints (color, shape, skin temperature, sensory abnormalities, etc.). Acupuncture and moxibustion treatment at this positive reaction place can improve the clinical efficacy. Meridian and acupoint diagnosis could provide basis for meridian syndrome differentiation, thus guiding the selection of acupoint prescriptions; it is also helpful to clarify the deficiency, excess, cold and heat of the disease nature, thus guiding the selection of acupuncture and moxibustion methods. In addition, it is an auxiliary method to estimate the prognosis and outcome of the disease.

Application of cochlear nerve action potential monitoring in the resection of vestibular schwannomas / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the application of cochlear nerve action potential (CNAP) monitoring in the resection of vestibular schwannoma, especially evaluating its significance for hearing preservation. Methods: From April 2018 to December 2021, 54 patients with vestibular schwannoma who underwent resection via retrosigmoid approach were collected in Chinese PLA General Hospital. Before surgery, all patients had effective hearing (AAO-HNS grade C or above). Brainstem auditory evoked potential (BAEP) combined with CNAP monitoring was performed during surgery. The CNAP monitoring was combined with continuous monitoring and cochlear nerve mapping. And patients were divided into hearing preservation group and non-preserved group according to postoperative AAO-HNS grade. SPSS 23.0 software was used to analyze the differences of CNAP and BEAP parameters between the two groups. Results: A total of 54 patients completed intraoperative monitoring and data collection, including 25 males (46.3%) and 29 females (53.7%), aged 27-71 years with an average age of 46.2 years. The maximum tumor diameter were (18.1±5.9) mm (range 10-34 mm). All tumors were totally removed with preserved facial nerve function (House-Brackmann grade I-II). The hearing preservation rate of 54 patients was 51.9% (28/54). During surgery, the V wave extraction rate of BAEP waveform was 85.2% (46/54) before tumor resection, 71.4% (20/28) in the hearing preservation group after tumor resection, and disappeared in the hearing preservation group (0/26). CNAP waveform was elicited in 54 patients during operation. Differences were found in the distribution of CNAP waveforms after tumor resection. The waveforms of the hearing-preserving group were triphasic and biphasic, while those in the non-preserving group were low-level and positive. For hearing preservation group, the amplitude of N1 wave after tumor resection was significantly higher than that before tumor resection[14.45(7.54, 33.85)μV vs 9.13(4.88, 23.35)μV, P=0.022]; However, for the non-preserved group, the amplitude of N1 wave after tumor resection was significantly lower than that before tumor resection [3.07(1.96, 4.60)μV vs 6.55(4.54, 9.71)μV, P=0.007]; After tumor resection, the amplitude was significantly higher than that of the unreserved group [14.45(7.54, 33.85)μV vs 3.07(1.96, 4.60)μV, P<0.001]. Conclusions: BAEP combined with CNAP monitoring is conducive to intraoperative hearing protection, and the application of cochlear nerve mapping can prompt the surgeon to avoid nerve injury. The waveform and N1 amplitude of CNAP after tumor resection have a certain value in predicting postoperative hearing preservation status.

Paroxysmal kinesigenic dyskinesia secondary to pseudohypoparathyroidism: a report of 2 cases and literature review / 中华神经科杂志

Objective:To explore the clinical characteristics of paroxysmal kinesigenic dyskinesia (PKD) secondary to pseudohypoparathyroidism (PHP), so as to improve the clinicians′ understanding of the disease.Methods:The clinical data of 2 cases of PKD secondary to PHP in Beijing Tiantan Hospital, Capital Medical University from June 2022 to October 2022 were summarized, and the related literature was reviewed to analyze the pathogenesis, clinical manifestations, laboratory examination and imaging characteristics of the disease, as well as its treatment and prognosis.Results:Ten cases of PKD secondary to PHP were previously reported. A total of 12 cases (including these 2 cases) were included in the study, of which 7 were males (7/12) and 5 were females (5/12). The onset age was 8-23 years. The clinical manifestations of the disease included paroxysmal limb torsion, limb stiffness, limb tremor, throwing movements, and dance like movements. There were 3 cases (3/12) who had seizure at the same time. Ten cases (10/12) were induced by exercise, while 2 cases (2/12) were not mentioned the inducing factor. Eleven cases (11/12) with paroxysmal symptoms lasting less than 2 minutes can be relieved automatically. Only 1 case had a family history. Laboratory examination of all patients showed low calcium, high phosphorus and significant elevation of parathyroid hormone. The head CT scans of 10 cases (10/12) showed multiple intracranial calcifications. There were 9 cases (9/12) alone received the supplementation of calcium and active vitamin D, while 3 cases (3/12) were additionally treated with antiepileptic drugs. All cases had good prognosis.Conclusions:PHP is a rare cause of secondary PKD. A small number of patients can have seizures at the same time. Most patients have a good prognosis after receiving calcium and active vitamin D supplementation.

Absence status epilepsy: a case report and literature review / 中华神经科杂志

Objective:To improve the knowledge of clinicians about absence status epilepsy (ASE).Methods:The ictal clinical manifestations, the interictal and ictal phase electroencephalogram (EEG) characteristics of 1 patient with ASE in the Department of Epilepsy, Beijing Tiantan Hospital, Capital Medical University on November 20, 2022 were analyzed, and the pathogenesis, clinical and EEG characteristics, differential diagnosis, treatment experience of ASE were summarized by retrospective analysis combined with previous literature review.Results:The patient was a 38-year female, with onset age of 18 years. The main clinical manifestations were repeated prolonged decline of consciousness with generalized tonic-clonic seizures. The long-range video EEG showed generalized spike-slow wave and slow wave sporadic in the interictal period, and continuous or sub-continuous 2.5-3.0 Hz generalized spike-slow wave discharge in the ictal period, and the laboratory and imaging findings were normal. A total of 17 patients consistent with ASE diagnosis were reported in 7 English literatures, and there were totally 18 cases (including this patient) analyzed in this paper. ASE is a specific subtype of idiopathic generalized epilepsy (IGE). The ratio of male to female was 1∶1. The onset age of 16/18 patients was in youth to middle age, and the average onset age was 25.3 years. Absence status epilepticus was the representative or main seizure type, and 15/18 patients presented with infrequent generalized tonic-clonic seizures, no independent myoclonic seizures were found. The interictal EEG showed generalized or incomplete generalized spike-wave or poly spike-wave discharges around 3.0 Hz under normal background, and may have focal non-localizing discharges. The ictal EEG presented as continuous or sub-continuous rhythmical or non-rhythmical≥2.5 Hz (mainly 2-4 Hz) generalized spike or poly spike-wave discharges. ASE mainly needed to be distinguished from de novo late-onset absence status epilepticus, adult IGE with phantom absences. The first choice of drugs included valproate sodium and lamotrigine. The correct drug selection resulted in better prognosis. Conclusions:ASE is clinically rare. By far, its pathogenesis is not well understood. ASE can easily be misdiagnosed as non-epileptic or focal seizure. For patients with late onset, infrequent generalized tonic-clonic seizures who are clinically consistent with IGE, ASE is necessary to be vigilant when there are long-term changes in consciousness, response ability and behavior. Long-term video EEG monitoring should be perfected in time to avoid misdiagnosis and mistreatment.

Role of epigenetic regulation of biological clock genes in tumors / 中国药理学通报

The circadian clock is regulated at the molecular level by transcriptional-translational feedback loop of clock genes, which ensures that a variety of physiological processes have a-round 24 h circadian rhythms, including cell metabolism, cell proliferation, cell apoptosis and tumorigenesis, to maintain the homeostasis. Thus, the disturbance of circadian clock will disrupt homeostasis, causing various diseases, including neoplasm, metabolic syndrome, Parkinson's disease, COPD and cardiovascular diseases. Disturbance of circadian clock is closely related with tumorigenesis, and acts on various molecules and pathways leading to tumorigenesis, including oncogene and tumor suppressor gene, cell cycle, metabolic reprogramming, immune escape, endocrine disruption, alteration of gastrointestinal microbiome. This review focuses on changes in clock genes expression which disrupt cell cycle and may play a role in tumorigenesis, and epi-geneties, an important way to regulate gene expression, which can alter clock gene expression, thus playing an important role in the process of " the alternation of clock gene expression-disruption of cell cycle-tumorigenesis".

Corticostriatal Neurons in the Anterior Auditory Field Regulate Frequency Discrimination Behavior / 神经科学通报·英文版

The anterior auditory field (AAF) is a core region of the auditory cortex and plays a vital role in discrimination tasks. However, the role of the AAF corticostriatal neurons in frequency discrimination remains unclear. Here, we used c-Fos staining, fiber photometry recording, and pharmacogenetic manipulation to investigate the function of the AAF corticostriatal neurons in a frequency discrimination task. c-Fos staining and fiber photometry recording revealed that the activity of AAF pyramidal neurons was significantly elevated during the frequency discrimination task. Pharmacogenetic inhibition of AAF pyramidal neurons significantly impaired frequency discrimination. In addition, histological results revealed that AAF pyramidal neurons send strong projections to the striatum. Moreover, pharmacogenetic suppression of the striatal projections from pyramidal neurons in the AAF significantly disrupted the frequency discrimination. Collectively, our findings show that AAF pyramidal neurons, particularly the AAF-striatum projections, play a crucial role in frequency discrimination behavior.

Concurrent Tuberculous Meningoencephalitis and Anti-NMDAR Encephalitis: A Case Report.

Background: Cases of tuberculosis triggering the development of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis are absent. Case Presentation: Herein, we report, for the first time, the case of a patient who developed anti-NMDAR encephalitis likely due to tuberculosis. The patient, a 33-year-old man, experienced weight loss during the previous 2 years, along with acute headache, fever, cognitive deficits, and right ophthalmoplegia. Based on these findings and on data from magnetic resonance imaging and cerebrospinal fluid antibody analysis, tuberculous meningoencephalitis combined with anti-NMDAR encephalitis was diagnosed. Marked clinical and brain imaging improvement were observed after antituberculosis and high-dose corticosteroid treatment initiation, which persisted during the 3 months of follow-up. Conclusions: This case suggests that anti-NMDAR encephalitis may arise after tuberculosis infection. Therefore, clinicians must be aware of this possibility, especially when cognitive and new neurological symptoms suddenly occur.
