ABSTRACT

@#Netrin-1 is a neuronal axon guidance factor, a soluble protein secreted by the cell floor, and is among the most widely studied members of the Netrins family.Netrin-1 has the diversity of receptors, and its binding to different receptors can activate different biological effects, resulting in multiple functions. Recent studies have revealed that Netrin-1 is closely associated with neural axon guidance, inflammatory responses, neovascularization, apoptosis, and other responses. It can act not only in the central nervous system, but also in many systemic diseases such as those of the respiratory and cardiovascular systems, making it an important target for the treatment of these diseases. In the field of ophthalmology, Netrin-1 is closely associated with optic nerve hypoplasia(ONH), corneal disease, diabetic retinopathy(DR), age-related macular degeneration(ARMD), and retinoblastoma(RB), and has very promising applications in the prevention and treatment of these diseases. In this review, we will explore the association of Netrin-1 with ocular diseases and its role.

ABSTRACT

Captopril can have nephrotoxic effects, which are largely attributed to accumulated renin and "escaped" angiotensin II (Ang II). Here we test whether angiotensin converting enzyme-1 (ACE1) inhibition damages kidneys via alteration of renal afferent arteriolar responses to Ang II and inflammatory signaling. C57Bl/6 mice were given vehicle or captopril (60 mg/kg per day) for four weeks. Hypertension was obtained by minipump supplying Ang II (400 ng/kg per min) during the second 2 weeks. We assessed kidney histology by periodic acid-Schiff (PAS) and Masson staining, glomerular filtration rate (GFR) by FITC-labeled inulin clearance, and responses to Ang II assessed in afferent arterioles in vitro. Moreover, arteriolar H2O2 and catalase, plasma renin were assayed by commercial kits, and mRNAs of renin receptor, transforming growth factor-β (TGF-β) and cyclooxygenase-2 (COX-2) in the renal cortex, mRNAs of angiotensin receptor-1 (AT1R) and AT2R in the preglomerular arterioles were detected by RT-qPCR. The results showed that, compared to vehicle, mice given captopril showed lowered blood pressure, reduced GFR, increased plasma renin, renal interstitial fibrosis and tubular epithelial vacuolar degeneration, increased expression of mRNAs of renal TGF-β and COX-2, decreased production of H2O2 and increased catalase activity in preglomerular arterioles and enhanced afferent arteriolar Ang II contractions. The latter were blunted by incubation with H2O2. The mRNAs of renal microvascular AT1R and AT2R remained unaffected by captopril. Ang II-infused mice showed increased blood pressure and reduced afferent arteriolar Ang II responses. Administration of captopril to the Ang II-infused mice normalized blood pressure, but not arteriolar Ang II responses. We conclude that inhibition of ACE1 enhances renal microvascular reactivity to Ang II and may enhance important inflammatory pathways.

ABSTRACT

Drug-induced liver injury (DILI) is one of the common adverse drug reactions and is the main cause of withdrawal of drugs after marketing, which has attracted more and more attention of the public, and herb-induced liver injury (HILI) is a special type of DILI. In recent years, the frequent occurrence of HILI not only seriously endangers the health of patients, but also causes the controversy over the safety of traditional Chinese medicine. Therefore, this article reviews the potential risk factors for HILI from the three aspects of "patient", "drug", and "use", so as to provide a basis for the objective identification, prevention, and control of HILI and a reference for the construction of traditional Chinese medicine pharmacovigilance system represented by liver injury.

ABSTRACT

Liver fibrosis is the common consequence of various chronic liver injuries and is mainly characterized by the imbalance between the production and degradation of extracellular matrix, which leads to the accumulation of interstitial collagen and other matrix components. Matrix metalloproteinases (MMPs) and their specific inhibitors, i.e., tissue inhibitors of metalloproteinases (TIMPs), play a crucial role in collagen synthesis and lysis. Through a literature review, this article reviews the experimental studies of liver fibrosis based on MMPs/TIMPs, summarizes the components that may exert an anti-liver fibrosis effect by affecting the expression or activity of MMPs/TIMPs, and attempts to clarify the mechanism of MMPs/TIMPs in regulating collagen homeostasis, so as to provide support for the development of anti-liver fibrosis drugs.

ABSTRACT

Inflammasomes play an important role in the innate immunity of the liver; however, the excessive activation of inflammasomes can lead to liver inflammation and injury. The mechanism of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome-mediated liver injury has been extensively studied. Related studies have shown that the development of various liver diseases may be associated with the excessive activation of inflammasomes, especially NLRP3 inflammasome. This article reviews inflammasomes, the activation mechanism of NLRP3 inflammasome, and the role of NLRP3 inflammasome in different liver diseases, so as to provide a reference for the treatment targets of liver diseases from the perspective of NLRP3 inflammasome.

ABSTRACT

Objective:To investigate the clinical efficacy of autologous peripheral blood hematopoietic stem cell transplantation (HSCT) in treatment of lymphoma.Methods:The clinical data of 41 lymphoma patients undergoing autologous peripheral blood HSCT at the Affiliated Hospital of Jining Medical University between January 2014 to December 2020 were retrospectively analyzed. There were 6 cases of Hodgkin lymphoma and 35 cases of non-Hodgkin lymphoma. The mobilization regimens included chemotherapy drugs + granulocyte colony-stimulating factor (G-CSF) + thrombopoietin (TPO) or chemotherapy drugs + G-CSF. The pre-conditioning schemes before transplantation were listed as follows: BEAM (mustine + cytarabine + etoposide + melphalan) regimen + decitabine in 26 patients, BEAM regimen in 12 patients, BEAM regimen + chidamide in 3 patients. The progression-free survival (PFS), overall survival (OS), related complications, prognoses after transplantation were observed. The effects of clinical staging, B symptom,International Prognostic Score Index (IPI), extranodal involved sites, hemoglobin (Hb), lactic dehydrogenase (LDH), β 2-microglobulin (β 2-MG), transplantation regimen and the status before transplantation on PFS and OS after transplantation were evaluated. Results:Among 41 patients, 37 patients (90.24%) achieved complete remission (CR), 2 patients (4.88%) achieved partial remission (PR) and 2 patients loss assessment data (4.88%) before autologous peripheral blood HSCT. The median karyocyte count was 12.74×10 8 /kg [(3.91-22.68)×10 8/kg] in 24 patients with the complete data of stem cell collection, the median CD34 positive cell count was 6.74×10 6/kg [(0.91-50.47)×10 6/kg]. All 41 patients had hematologic reconstruction. The median time of platelet implantation was 11 d (7-32 d) and the median time of granulocyte implantation was 9 d (8-16 d). All patients achieved CR after transplantation and no one case had transplantation-related death. By the end of follow-up, 33 cases (80.49%) had no progression of disease, 8 cases (19.51%) died. The OS rates of 12-month, 24-month and 72-month were 93.4%, 85.3% and 60.9%, respectively after transplantation. The PFS rates of 12-month, 24-month and 72 month were 93.3%, 84.0% and 84.0%, respectively. Median PFS and OS had not been reached. There were no statistically significant differences in the PFS and OS of patients with different gender, clinical staging, B symptom, IPI score, extranodal involved sites, Hb, LDH, β 2-MG and the status before transplantation(all P > 0.05) . The PFS and OS of patients receiving BEAM regimen + decitabine were better than those of patients receiving BEAM regimen alone (all P < 0.05). Conclusions:Autologous peripheral blood HSCT is effective in treatment of lymphoma. Moreover, BEAM regimen + dicitabine preconditioning regimen can achieve longer survival time compared with BEAM regimen alone.

ABSTRACT

OBJECTIVE@#To compare the clinical therapeutic effect on diarrhea-predominant irritable bowel syndrome (IBS-D) of spleen deficiency and damp excess among fire needling therapy with filiform needle combined with acupoint application therapy, simple acupoint application therapy and pinaverium bromide tablets, and explore the mechanism on the improvements in IBS-D.@*METHODS@#A total of 150 patients with IBS-D of spleen deficiency and damp excess were randomized into a combined treatment group (50 cases, 14 cases dropped off), an acupoint application group (50 cases, 16 cases dropped off ) and a western medication group (50 cases, 13 cases dropped off ). In the western medication group, pinaverium bromide tablets were prescribed for oral administration, 50 mg per time, three times a day. In the acupoint application group, the herbal plaster of @*RESULTS@#Except the score for abdominal pain in the acupoint application group and the scores for abdominal pain and abdominal distention in the western medication group after 7 days of treatment, the scores for abdominal pain, abdominal distention, defecation frequency, stool form and incomplete bowel movement after 7 and 28 days of treatment were all reduced as compared with those before treatment in each group separately (@*CONCLUSION@#The combined treatment with the fire needling therapy with filiform needle and the acupoint application therapy effectively relieves the clinical symptoms, improves the quality of life and strengthens the immunity in the patients with IBS-D. The therapeutic effect of this combined regimen is better than either simple acupoint application therapy or the oral medication of pinaverium bromide. The mechanism may be related to the regulation of the levels of T lymphocyte subsets and the modulation of the expressions of 5-HT3R and 5-HT4R mRNA in colon tissue.

ABSTRACT

Objective:To observe the clinical characteristics of patients with visual impairment caused by fungal sphenoid sinusitis and analyze the influencing factors related to visual prognosis.Methods:A retrospective clinical study. From January 2006 to December 2020, 44 patients (55 eyes) with visual impairment caused by fungal sphenoid sinusitis confirmed by imaging and pathological examination in the Department of Ophthalmology of Beijing Tongren Hospital were included in the study. Patients was first diagnosed in the Department of Ophthalmology due to monocular or binocular vision loss, or binocular diplopia, limited eye movement and ptosis. All patients underwent visual acuity examination and fundus color photography. CT examination of paranasal sinus or orbit was performed in 37 cases; magnetic resonance imaging (MRI) of paranasal sinus, brain or orbit was performed in 34 cases. All patients underwent endoscopic sinus opening combined with intrasinus lesion clearance; 14 cases were treated with antifungal drugs after operation. The average follow-up time was 59.61±37.70 months. Comparison of clinical characteristics between invasive and non-invasive fungal sphenoid sinusitis were by χ 2 test or Fisher exact test. The influencing factors with P<0.2 in univariate analysis were selected for multivariate regression analysis. Results:Among the 44 patients, there were 19 males and 25 females; the ratio of male to female was 1:1.3; the average age of visual symptoms was 61.48 ± 12.17 years; 23 cases (52.3%, 23/44) suffered from immune dysfunction, including 21 cases of diabetes mellitus. The visual acuity decreased in 33 cases (44 eyes) (75.0%, 33/44). There were 15 cases of binocular diplopia with eye movement disorder (34.0%, 15/44), including 6 cases with visual impairment. The visual acuity of the affected eye was no light perception-0.8. There were 35 cases with headache (79.5%, 35/44). Nasal symptoms were found in 14 cases (31.8%, 14/44). There were 40 and 4 cases of Aspergillus and Mucor infection in sphenoid sinus, respectively. Among the 37 cases who underwent CT examination of paranasal sinus or orbit, there were soft tissue filling in the sinus cavity, including 19 cases of high-density calcification in the sinus cavity (51.4%, 19/37); bone defect of sinus wall were in 24 cases (64.9%, 24/37). There were 26 cases (70.3%, 26/37) of sinus wall osteosclerosis. MRI of paranasal sinus, brain or orbit was performed in 34 cases. T1WI of sphenoid sinus lesions showed low signal, high signal and equal signal in 14, 10 and 9 cases, respectively; T2WI showed high signal, low signal and equal signal in 13, 16 and 2 cases respectively. After enhancement, the lesions were strengthened in 11 cases, no obvious enhancement in 23 cases, and the surrounding mucosa was thickened and strengthened. The lesions involved the orbital apex and cavernous sinus in 18 and 16 cases, respectively; orbital apex and cavernous sinus were involved in 12 cases. Six months after operation, visual acuity was significantly improved in 27 eyes (65.9%, 27/41); visual acuity did not improve in 14 eyes (34.1%, 14/41). Multivariate regression analysis showed that the change of sinus wall osteosclerosis was associated with higher visual acuity improvement rate (odds ratio= 0.089, 95% confidence interval 0.015-0.529, P=0.008). Conclusions:Fungal sphenoid sinusitis related visual impairment is relatively common in elderly female patients with low immune function; monocular vision loss with persistent headache is the most common clinical symptom; imaging findings of sphenoid sinus lesions are an important basis for diagnosis. Sphenoid sinus opening combined with sinus lesion clearance is an effective treatment. After operation, the visual acuity of most patients can be improved. The prognosis of visual acuity was relatively good in patients with hyperplasia and sclerosis of sphenoid sinus wall bone.

ABSTRACT

Objective:To summarize the medium-term outcomes of single kidney transplantation from senile deceased donors aged above 65 years.Methods:Forty-three kidney recipients from donors aged above 65(old-aged donor group, OAD) and 43 kidney recipients of the same age and gender from donors aged 18 to 49 years(standard-criteria donor group, SCD) were retrospectively reviewed.The survival outcomes of patients and grafts, renal functions, the incidence of delayed graft function(DGF)and other complications were recorded within the 3-year follow-up post-transplantation.Results:The 3-year patient survival rates were 95.3% both in OAD and SCD and the 3-year death-censored graft survival rates 92.7% and 97.6% respectively.The serum levels of creatinine were significantly higher in OAD than that in SCD( P<0.05). And lower estimated glomerular filtration rate(eGFR)was found in OAD as compared with SCD( P<0.05). No significant difference existed in the incidence of DGF(OAD 20.9% and SCD 18.6%, P>0.05), acute rejection (OAD 4.7% and SCD 2.3%, P>0.05)or proteinuria(OAD 27.9%and SCD 14.0%, P>0.05). Conclusions:Single kidney transplantation from old-aged deceased donors may achieve excellent medium-term survival outcomes of patients and grafts.It can expand the donor pool though kidney functions were not as good as those of SCD.

ABSTRACT

BACKGROUND@#Postural tachycardia syndrome (POTS) is a common childhood disease that seriously affects the patient's physical and mental health. This study aimed to investigate whether pre-treatment baseline left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) values were associated with symptom improvement after metoprolol therapy for children and adolescents with POTS.@*METHODS@#This retrospective study evaluated 51 children and adolescents with POTS who received metoprolol therapy at the Peking University First Hospital between November 2010 and July 2019. All patients had completed a standing test or basic head-up tilt test and cardiac echocardiography before treatment. Treatment response was evaluated 3 months after starting metoprolol therapy. The pre-treatment baseline LVEF and LVFS values were evaluated for correlations with decreases in the symptom score after treatment (ΔSS). Multivariable analysis was performed using factors with a P value of  0.050). However, responders had significantly higher baseline LVEF (71.09% ± 4.44% vs. 67.17% ± 4.88%, t = -2.789, P = 0.008) and LVFS values (40.00 [38.00, 42.00]% vs. 36.79% ± 4.11%, Z = -2.542, P = 0.010) than the non-responders. The baseline LVEF and LVFS were positively correlated with ΔSS (r = 0.378, P = 0.006; r = 0.363, P = 0.009), respectively. Logistic regression analysis revealed that LVEF was independently associated with the response to metoprolol therapy in children and adolescents with POTS (odds ratio: 1.201, 95% confidence interval: 1.039-1.387, P = 0.013).@*CONCLUSIONS@#Pre-treatment baseline LVEF was associated with symptom improvement after metoprolol treatment for children and adolescents with POTS.

ABSTRACT

OBJECTIVE:To provide reference for establishing stan dardized construction standard system of “internet+TCM pharmacy”. METHODS : Questionnaire through literature review , investigation and expert consultation were compiled. A questionnaire survey was carried out among TCM staff to understand the current situation and problems of “internet + TCM pharmacy”in Chinese medical institutions. Based on the results of the questionnaire ,a frame of standardized construction standard system for “internet+TCM pharmacy ”was tried to constructed. RESULTS & CONCLUSIONS:A total of 74 questionnaires were distributed and 74 were returned ,including 1 invalid questionnaire ,with an effective rate of 98.65%. Among the 73 respondents, more than 60% were from TCM hospitals ,or with the title of vice senior or above ,and 55(75.3%)were national TCM characteristic technology inheritance talents. The survey results showed that more than 80% of TCM pharmacies in medical institutions were equipped with full-time reviewers ,provided decocting service ,set up decocting room ,and carried out distribution service,and could achieve the same-day or part of the same-day delivery. More than half of the respondents believed that the prescriptions of TCM decoction pieces in their medical institutions were issued in strict accordance with the relevant requirements , the rational drug use monitoring software was used ,and the error analysis of relevant work links was carried out regularly , prescription coping training was regularly carried out for dispensers ,and decoction knowledge and operation process training were carried out for decoction personnel. However ,the vast majority of respondents (67,accounting for 91.8%)thought that their medical institutions only used traditional methods to control and evaluate the quality of finished decoction products. The results of the evaluation of the importance of 6 links and 17 key points of operation showed that the highest concentration of opinions was the quality of decoction pieces ,and the key points of operation were special drug treatment. The results of principle component analysis and maximum variance analysis showed that current construction of “internet+TCM pharmacy ”was mainly reflected in the two dimensions as TCM decocting ,consultation and distribution servi ces. Statistical analysis indicated that there were significant differences in staff training ,awareness of laws and policies , regular error analysis ,patient satisfaction survey ,optimization of payment and consulting services among different levels and categories institutions (P<0.05). It was necessary to carry out the standardization construction of “internet+TCM pharmacy”. It is suggested that the standard system for standardized construction of“Internet + TCM pharmacy ”should be established from 5 aspects:basic construction conditions ,the standardization of procurement and acceptance ,the standardization of dispensing ,the standardization of decocting and distribution service and the standardization of pharmaceutical consultation services.

ABSTRACT

This paper introduced the basic definition, application scope, advantages and challenges of the master protocol, basket design, umbrella design and platform trial, and put forward the idea of using master protocol, basket design and umbrella design in Chinese medicine(CM) by considering the characteristics of CM and research experiences. The author pointed out that master protocol, basket design and umbrella design, as a high-efficiency research and design strategy, can be used in the clinical research on the treatment of the same disease with different therapies, the treatment of different diseases with the same therapy and the combination of diseases and CM syndromes. In particular, the exploration from the classification of CM syndromes can supplement the gaps in the cli-nical research on CM syndromes. In the application of such designs, it is also necessary to pay attention to their potential challenges and develop reasonable and feasible plans on research implementation, management and statistical analysis in advance to meet these challenges.

ABSTRACT

Objective::To investigate the effect of serum containing Yanghetang (YHT) on the apoptosis of MCF-7 cells in breast cancer based on the mitogen-activated protein kinase (p38)/signal transduction and transcriptional activator 3 (STAT3) signal pathway. Method::YHT liquid with crude drug 1 g·mL-1 was prepared. Female SD rats were randomly divided into control group (distilled water), and high, medium and low-dose YHT groups (24, 12, 6 g·kg-1). YHT-medicated serum was prepared, and 10%medicated serum was used to intervene MCF-7 cells. Cell proliferation and cytotoxicity assay (CCK-8) was used to detect the effect of serum containing YHT on MCF-7 cell proliferation, apoptosis of MCF-7 cells was detected by flow cytometry protein expressions of p38 and STAT3 were detected by Western blot, Quantitative Real-time PCR (Real-time PCR) was used to detect the expressions of B-cell lymphoma/leukemia-xl(Bcl-xl) and Survivin mRNA. Result::CCK-8 assay showed that YHT serum inhibited the proliferation of MCF-7 cells in a time and dose-dependent manner compared with the blank group. The inhibitory effect was most obvious in the high-dose group, with the inhibition rates of 38%, 45%and 54%at different time points (P<0.01). Flow cytometry showed that, compared with the blank group, the apoptosis rate in the medium and high-dose groups increased significantly in a dose-dependent manner, with the apoptosis rates at 11.6%and 16.5%respectively (P<0.05, P<0.01). Western blot analysis showed that, compared with the blank group, the expressions of p38 and STAT3 protein was decreased in high, medium-dose YHT groups (P<0.01) in a dose-dependent manner. Compared with the blank group, the expressions of Bcl-xl and Survivin mRNA were decreased in high, medium-dose YHT groups (P<0.05, P<0.01) in a dose-dependent manner. Conclusion::YHT serum can promote the apoptosis of MCF-7 cells in breast cancer, which may be related to the p38/ STAT3 signaling pathway.

Objective:To observe the efficacy and adverse reactions of adrenocorticotropic hormone (ACTH) in the treatment of recurrent frequently relapsing nephrotic syndrome (FRNS), and explore the feasibility of treatment of ACTH in children.Methods:From November 2017 to June 2018, in the First Affiliated Hospital of Xinxiang Medical University of a total of 32 cases of FRNS ACTH therapy were all the role of ACTH consecutive 3-8 courses of treatment (when the dosage of prednisone was less than or equal to 0.5 mg/kg, 0.4 U/kg ACTH should be used every day.After 3 days of continuous application, the dosage of Prednisone should be reduced to 1.25-5.00 mg.ACTH was used for 3 days as a course of treatment, and continued to use ACTH for 2 courses until corticosteroid stopped). The number of recurrence, Prednisone maintenance dose, immunosuppressive use, serum cortisol and other relevant experimental indicators and adverse reactions were recorded during the follow-up period after ACTH treatment, and were followed up for 8-15 months.Results:Among the 32 children, the onset age (53.47±25.81) months, the course of disease (35.25±23.87) months, 22 patients (68.75%) had no recurrence after corticosteroid withdrawal, 7 patients (21.87%) had recurrence after corticosteroid withdrawal, and 3 patients (9.37%) had recurrence during corticosteroid withdra-wal.Compared with before ACTH treatment, Prednisone was significantly decreased[(0.08±0.14) mg/(kg·d) vs. (0.23±0.23) mg/(kg·d)], and the difference was statistically significant ( t=3.661, P<0.05), the number of immunosuppressant cases decreased significantly[42.38%(12/32 cases) vs. 58.62%(17/32 cases), χ2= 14.500, P<0.05]. Serum cortisol was measured at 8 Am increased significantly[(11.78±4.64) μg/dL vs. (4.42±3.13) μg/dL, t=7.340, P<0.05]. The results were stable during follow-up, with 2 patients presenting with systemic urticaria once and 1 patient presenting with headache after infusion. Conclusions:ACTH therapy is safe and effective in hormone therapy for child with FRNS, and less adverse reactions.

ABSTRACT

Objective@#To analyse the outcomes and the prognostic factors of patients with sinonasal malignancies following endoscopic endonasal approach, and to compare the pre- and post-operative quality of life.@*Methods@#A retrospective single-center review of 79 patients who underwent endoscopic endonasal approach for sinonasal malignancies in Beijing Tongren Hospital from October 2004 to March 2017 was performed, including 51 males and 28 females, with a median age of 48 years. Data of demography, imaging (including nasal CT and MRI before operation), histopathology and treatment strategy were collected. Recurrence and distant metastasis were diagnosed according to endoscopic examination, MRI and general check-up after surgery. Pre- and post-operative quality of life scores were obtained by sinonasal outcome test-22, visual analog scale and anterior skull base surgery questionnaire. SPSS 22 software was used for statistical analysis.@*Results@#The study consisted of 13 pathological types with sinonasal T1-T4 stage tumors, including cervical lymph nodes and/or distant metastasis. All patients underwent endoscopic endonasal approach surgery. After 43 months of median follow-up time, the overall, disease-free, and recurrence-free survival rates at 1, 3, 5 and 10 years was 97.4%, 92.5%, 92.5% and 83.7%; 83.2%, 68.3%, 56.8% and 33.6%; 84.5%, 66.6%, 58.0% and 34.4%, respectively. Postoperative recurrence was an independent risk factor affecting the overall survival rate (HR=8.852, P=0.044), and preoperative recurrence (secondary surgery) was an independent risk factor affecting the disease-free and recurrence-free survival rate (HR value was 2.237 and 2.095 respectively, P value was 0.029 and 0.047 respectively). After surgery, the olfaction and nasal scab got worse, while the nasal obstruction and breathing were improved.@*Conclusions@#Endoscopic endonasal approach for sinonasal malignancies can achieve satisfactory outcomes, and has obvious advantages in improving the quality of life. Postoperative recurrence and preoperative recurrence are the prognostic factors.
