ABSTRACT

Blocking immune checkpoint programmed cell death receptor 1 (PD-1) or programmed death receptor-ligand 1 (PD-L1) can enhance anti-tumor activity of effector T cells. However, the lack of response in many patients to PD-1/PD-L1 therapy remains a question. Improving the immunosuppressive tumor microenvironment (TME) to enhance the efficacy of immune checkpoint inhibitors has become a promising cancer treatment strategy. We constructed a liposome system (PD-L1/siCXCL12-Lp) of CXCL12 siRNA and anti-PD-L1 peptide with matrix metalloproteinases (MMPs) responsiveness, which combined the TME regulation of siCXCL12 and the immune regulation of anti-PD-L1 peptide. All animal experiments were approved by the Biomedical Ethics Committee of Peking University. The authors found that PD-L1/siCXCL12-Lp directly down-regulated the expression of CXCL12 in vitro (33.8%) and in vivo (15.5%). It also effectively increased the ratio of CD8+/Treg by 20.0%, which helped the anti-PD-L1 peptide to better exert its immune effect. The combination therapy significantly inhibited tumor growth (52.08%) with great safety, which explored a new idea for cancer immunotherapy.

ABSTRACT

COVID-19 pandemic caused by SARS-CoV-2 infection severely threatens global health and economic development. No effective antiviral drug is currently available to treat COVID-19 and any other human coronavirus infections. We report herein that a macrolide antibiotic, carrimycin, potently inhibited the cytopathic effects (CPE) and reduced the levels of viral protein and RNA in multiple cell types infected by human coronavirus 229E, OC43, and SARS-CoV-2. Time-of-addition and pseudotype virus infection studies indicated that carrimycin inhibited one or multiple post-entry replication events of human coronavirus infection. In support of this notion, metabolic labelling studies showed that carrimycin significantly inhibited the synthesis of viral RNA. Our studies thus strongly suggest that carrimycin is an antiviral agent against a broad-spectrum of human coronaviruses and its therapeutic efficacy to COVID-19 is currently under clinical investigation.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy.@*METHODS@#A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted.@*RESULTS@#In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period.@*CONCLUSION@#HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation.

ABSTRACT

OBJECTIVE@#To study the clinical features of children with Guillain-Barré syndrome (GBS) and the significance of Brighton criteria in childhood GBS.@*METHODS@#A retrospective analysis was performed on the medical data of 72 children with GBS. Brighton criteria were used for the grading of diagnostic certainty (level 1 as the highest level, and level 4 as the lowest level). A Spearman's rank correlation analysis was used to evaluate the correlation of auxiliary examinations with the level of diagnostic certainty of Brighton criteria.@*RESULTS@#A total of 72 children with GBS were enrolled, with a mean age of onset of (98±32) months. All children (100%, 72/72) had weakness of bilateral limbs and disappearance or reduction of tendon reflex, and limb weakness reached the highest level of severity within 4 weeks. Of all the 72 children, 68 (94%) had positive results of neural electrophysiological examination and 51 (71%) had positive results of cerebrospinal fluid (CSF) examination, and the positive rate of neural electrophysiological examination was significantly higher than that of CSF examination (@*CONCLUSIONS@#Most of the children with GBS meet Brighton criteria level 1, and the positive results of CSF examination and neural electrophysiological examination play an important role in improving the level of diagnostic certainty of Brighton criteria. Neural electrophysiological examination has a higher positive rate than CSF examination in the early stage of the disease.

ABSTRACT

Objective:To evaluate the effect of hierarchical diagnosis and treatment model of childhood bronchial asthma in Shanghai Pudong New Area.Methods:According to the principle of proximity, children aged 6 months-17 years who were diagnosed with bronchial asthma at Shanghai Children′s Medical Center from July 2016 to May 2017 were divided into two cohorts: the specialized hospital group and the community hospital group.Twelve months of treatment and follow-up were conducted.The asthma control level, Childhood Asthma Control Test (C-ACT) score, medication adherence and health economic indicators were collected.Results:A total of 524 children were included for data analysis and divided into the specialized hospital group (300 cases) and the community hospital group (224 cases). According to the Global Initiative for Asthma(GINA) criteria, there was no statistical difference in monthly asthma control level between the two groups (all P>0.05). In the 12 th month, the well-controlled rate of the specialized hospital group increased by 12.4% ( P<0.01), and that of the community hospital group increased by 22.9% ( P= 0.015). According to the C-ACT criteria, there was no statistical difference in the monthly well-controlled rate between the two groups (all P>0.05), and the rate maintained an upward trend.The rates of patients with good compliance in the specialized hospital group and the community hospital group at the 12 th month of hierarchical diagnosis and treatment were 78.3%(235/300 cases) and 75.0%(168/224 cases), respectively, and the difference was not statistically significant ( P=0.370). After 12 months of hierarchical diagnosis and treatment, the number of asthma attacks were 1.0 and 2.0 ( P=0.269), and the hospitalization rates for asthma were 3.0%(9/300 cases) and 4.9%(11/224 cases), respectively in the specialized hospital group and the community hospital group, and the diffe-rence was not statistically significant ( P=0.259); the number of respiratory infections in the specialized hospital group (2.0 times) was lower than that in the community hospital group (3.0 times), and the total cost of treatment in the community hospital group (2 471.5 Yuan) was lower than that in the specialized hospital group (3 445.5 Yuan), and the difference was statistically significant ( Z=-3.308, -3.336, all P<0.01). Twelve months after hierarchical diagnosis and treatment, the number of asthma attacks, the number of respiratory infections and the hospitalization rate for asthma in the two groups were all lower than those in the first 12 months of hierarchical diagnosis and treatment, and the difference was statistically significant (all P<0.01). Conclusions:Hierarchical diagnosis and treatment model of childhood asthma in Shanghai Pudong New Area can improve asthma control level, C-ACT score and asthma medication adherence, and enhance health economic benefits, thus it′s an effective way to manage childhood asthma.

ABSTRACT

Objective:To investigate the role of microRNA-187-5p (miR-187-5p) on osteoporosis (OP) as well as the related molecular mechanism.Methods:The level of miR-187-5p and tartrate-resistant acid phosphatase (TRAP, the osteoclast marker) was quantitatively detected in TRANKL-induced OP group and control (con) group by reverse transcription-quantitative PCR (RT-qPCR) ; Cell counting kit 8 (CCK8) was used to measure the viability of murine macrophage cell line (RAW264.7) ; Western blot was used to detect the expression of p65 and TNFα. Moreover, the dual luciferase reporter assays was applied to detect the interaction between miR-187-5p and p65.Results:The osteoclast proliferation determined by CCK8 and the mRNA level of TRAP detected by RT-qPCR demonstrated that the growth of osteoclast was inhibited in OP group compared with that in con group ( P=0.008; P=0.017) , which reversed by miR-187-5p mimic stimulation ( P=0.023; P=0.037) . The miR-187-5p was lowly expressed in OP group compared with that in con group ( P=0.031) ,which was increased by miR-187-5p mimic treatment compared with miR-187-5p NC treatment ( P=0.041) . Moreover, western blot indicated that the protein level of p65 and TNFα in OP group were up-regulated compared with that in con group ( P=0.034; P=0.024) , which restored by the miR-187-5p mimic co-incubation ( P=0.028; P=0.036) . Moreover, the RT-qPCR indicated that the mRNA level of p65 in OP group was also increased compared with that in con group ( P=0.039) , and the miR-187-5p mimic co-incubation decreased the mRNA level of p65, compared with miR-187-5p NC group ( P=0.025) . The dual luciferase reporter assays indicated that there was an interaction between miR-187-5p and p65. Conclusion:miR-187-5p alleviates OP through inhibiting the activity of osteoclast via RANKL/NFκB signaling

ABSTRACT

Objective:To observe the effect of modified Si Junzitang on the level of lactic acid in gastric mucosa and the expression of Carboxylic acid transporter 1(MCT1), monocarboxylic acid transporter 4(MCT4), and extracellular matrix metalloproteinase inducer (CD147)in rats with gastric precancerous lesions(GPL). Method:Seventy-four SD male rats were randomly divided into normal group (12 rats) and model group (62 rats). <italic>N</italic>-methyl-<italic>N'</italic>-nitro-<italic>N</italic>-nitrosoguanidine(MNNG)-ammonia compound method was used to establish GPL rat models, and at the 9<sup>th</sup> week, the model rats were randomly divided into model group, folic acid group(2.7 mg·kg<sup>-1</sup>), modified Si Junzitang high, medium and low dose groups(12.6, 6.3, 3.15 g·kg<sup>-1</sup>), with 12 rats in each group. After intragastric administration for 12 weeks, the general conditions of the rats were observed. Hematoxylin-eosin(HE)staining was used to observe the histopathological changes of gastric mucosa in rats, chemical colorimetry was used to detect the content of lactic acid in gastric mucosa; immunohistochemistry and real-time polymerase chain reaction(Real-time PCR)were used to detect MCT1, MCT4, CD147 protein and mRNA expression in gastric mucosal tissues. Result:Modified Si Junzitang significantly improved the pathological manifestations in GPL rats such as gastric mucosal epithelial gland structure, disorder of arrangement and cell atypia. Compared with the normal group, the lactic acid content of the gastric mucosa tissue in the model group increased significantly(<italic>P</italic><0.01), and the protein and mRNA expressions of MCT1, MCT4, CD147 significantly increased(<italic>P</italic><0.05, <italic>P</italic><0.01). Compared with the model group, the lactic acid content in each dose group of modified Si Junzitang was significantly reduced(<italic>P</italic><0.05, <italic>P</italic><0.01), and the protein expression levels of MCT4 and CD147 were also significantly reduced in each dose group of modified Si Junzitang(<italic>P</italic><0.05, <italic>P</italic><0.01). The mRNA expression of MCT4 was significantly reduced in the middle and high dose groups(<italic>P</italic><0.05, <italic>P</italic><0.01), and the mRNA expression of CD147 was significantly reduced in the high dose group(<italic>P</italic><0.05). Modified Si Junzitang showed no significant regulatory effect on MCT1. Conclusion:Modified Si Junzitang can significantly improve the abnormal histopathology of gastric mucosal epithelium in GPL model rats. Its mechanism may be related to down-regulating the overexpression of MCT4 and CD147, inhibiting lactic acid outflow, and improving the acidic microenvironment of gastric mucosal epithelium.

ABSTRACT

Six dimensional syndrome differentiation theory, put forward by professor GU Xiao-hong at Beijing University of Chinese Medicine based on her theoretical teaching and clinical experience, emphasizes that the syndrome differentiation should be carried out from six dimensions including etiology, disease location, disease stage, disease condition, pathology, and disease nature, which is conducive to clinical thinking training and formation of traditional Chinese medicine (TCM). The differentiation and treatment of Baihutang syndrome frequently seen in cold damage and warm disease still need to be explored. Guided by the six dimensional syndrome differentiation theory coupled with diverse viewpoints of cold damage and warm disease schools, this paper summarized and reinterpreted the understandings and thoughts of GU Xiao-hong and YU He, warm disease specialists of two generations. Considering the lung-stomach dysfunction caused by the internal invasion of exogenous pathogens, Baihutang syndrome was staged into Qi aspect. In this stage, exuberant pathogens and sufficient healthy Qi allowed the prevailing of internal heat and the consumption of body fluid, manifested as high fever, profuse sweating, thirst, and the pulse corresponding to interior excess and heat syndrome. This paper also pointed out that the Baihutang syndrome involved both lung and stomach, and the adoption of Baihutang contributed to preventing tu from restricting shui in the case of extreme excess of Yang brightness and protecting the kidney Yin. As revealed by the dynamic analysis of prognosis of Baihutang syndrome based on the six dimensional syndrome differentiation theory, even though the Baihutang syndrome could be present in both cold damage and warm disease, the specific disease stage, transmission and change, condition, prognosis, pathology, and medication differed. On this basis, a series of prescriptions have been modified from Baihutang, which has expanded the application scope of Baihutang and enriched its research value, thus better promoting its clinical application.

ABSTRACT

Objective:To create a prediction model that could be used to stratify the risk of cardiac rehabilitation in patients with stable coronary artery disease by using test data based on cardiopulmonary exercise testing (CPET) and general clinical data. Methods:A total of 114 patients with stable coronary artery disease were consecutively enrolled from the Cardiology Coronary Artery Disease Database of our hospital from December, 2014 to December, 2018, all the patients underwent CPET before coronary angiography. LASSO was used for feature selection. A nomogram was formulated based on the results of multivariate Logistic regression analysis using the RMS package of R. The predictive power was assessed with Receiver Operating Characteristic Curve. Results:Seven predictors were identified based on LASSO: coronary angiography results, the maximum value of ventilatory equivalent for carbon dioxide (EqCO2max), lymphocyte count, fasting blood glucose levels, cardiac muscle enzyme positivity, blood homocysteine and blood urea nitrogen levels. Combined with clinical experience and weighting analysis, the final four factors were included for Logistic regression modeling: coronary angiography results, EqCO2max, lymphocyte count and fasting blood glucose levels. The area under the curve was 0.875 for the model. Conclusion:EqCO2max and lymphocyte count are key predictors for stable coronary heart disease and can be used to identify patients at high risk for cardiac rehabilitation. A risk stratification model based on CPET and laboratory tests can be used to assess risk stratification for cardiac rehabilitation in patients with stable coronary artery disease.

ABSTRACT

Objective:To investigate the status of cardiac rehabilitation after percutaneous coronary intervention (PCI) in rural areas. Methods:A total of 2264 patients after PCI in our hospital from January, 2016 to December, 2019 were selected. The awareness rate of patients on cardiac rehabilitation knowledge was investigated through WeChat, telephone and questionnaire. Patients were divided into rehabilitation group (n = 326) and non-rehabilitation group (n = 1809) according to whether they participated in cardiac rehabilitation. Results:There were 2135 valid questionnaires. The awareness rate of cardiac rehabilitation in PCI patients with coronary heart disease in rural areas was 44.9%, the participation rate was 15.2%, and the participation rate of outpatient heart rehabilitation was only 0.56%. The scores of the MOS Item Short Form Health Survey (SF-36) were higher in the rehabilitation group than in the non-rehabilitation group (t > 4.65, P < 0.05). Conclusion:In rural areas, the knowledge of cardiac rehabilitation is poor for patients after PCI, the participation rate is low, the control rate of risk factors is low, and most patients do not return to farm work. It is important to take a way to improve the awareness and participation of cardiac rehabilitation for patients after PCI, to ensure the exact control of cardiovascular risk factors of patients.
