Autophagy-regulated strategies in pre-clinical studies of inflammatory bowel disease / 药学学报

Inflammatory bowel disease (IBD) is a group of chronic idiopathic colorectal inflammatory diseases with a progressive and unpredictable course, including ulcerative colitis (UC) and Crohn's disease (CD). Abnormal intestinal inflammation and immune response contribute to the pathogenesis of IBD. Autophagy as an essential catabolic process in cells, has been demonstrated to have associations with a variety of inflammatory diseases including IBD. Here, we review the relationship between autophagy dysfunction and the process of IBD. The progress of several autophagy regulators for intestinal epithelial cells and macrophages is highlighted (inflammasome inhibitors, intestinal flora regulators, and other signal regulators) in the current studies on IBD.

Characteristics of Self-esteem and Life Position of Children with Mild Intellectual Disability / 中国康复理论与实践

Objective To study the characteristics of self-esteem and life position of children with mild intellectual disability and the effects of adaptive behavior on self-esteem and life position. Methods From November, 2019 to January, 2020, 162 children with mild intellectual disabilities in Shanghai were investigated and evaluated with Adaptive Behavior Assessment System-Second version (ABAS-Ⅱ), Rosenberg Self-esteem Scale (SES) and Life Position Scale (LPS). Structural equation model was used to explore the specific effects of adaptive behavior on self-esteem and life position. Results The score of SES was (23.52±5.49), which was slightly lower than the norm (28.75±4.86) (t = -12.140, P < 0.001). The score of LPS was (50.76±11.85). Structural equation model showed that conceptual skill in adaptive behavior negatively affected life position (B = -0.450, P < 0.05); social skill (B = 0.480, B = 0.331, P < 0.05) and practical skill (B = 0.490, B = 0.294, P < 0.05) positively affected both life position and self-esteem. Conclusion Self-esteem decreases in children with mild intellectual disability, and the life position reached the theoretical median level. Among adaptive behavior, both social skill and practical skill positively affect self-esteem and life position, while conceptual skill negatively affects life position.

Effect of Shaoyaotang on Expressions of TLR4, NF-κB p65 and IL-6 in Rats with Damp-heat Ulcerative Colitis / 中国实验方剂学杂志

Objective:To explore the mechanism of Shaoyaotang in the treatment of ulcerative colitis (UC) based on toll-like receptor 4 (TLR4)/nuclear factor kappaB (NF-κB) signaling pathway. Method:A total of 50 Wistar rats were selected, including half male and half female. The damp-heat UC rat model was replicated by the methods of the combination of diseases and syndromes and the combination of 2, 4, 6-nitrobenzene sulfonic acid (TNBS) and ethanol. After the successful modeling, the model rats were randomly divided into model group, salazulesulfonate group, and low, medium and high-dose Shaoyaotang groups, and 10 rats (half male and half female) were selected as the blank control group. Low, medium and high-dose Shaoyaotang groups were given 6, 12, 24 g·kg-1 by gavage, and salazonyl arsenic group was given 1 g·kg-1 by gavage. Blank control group was given the equal volume of normal saline for 21 consecutive days. Colon samples were collected after the last administration, and the expressions of TLR4, NF-κB p65 and IL-6 mRNA in colon tissues were detected by fluorescent quantitative polymerase chain reaction (Real-time PCR）, and the expressions of TLR4, NF-κB p65 and IL-6 protein in colon tissues were detected by Western blot. Result:Compared with the blank control group, the relative expressions of TLR4, NF-κB p65, IL-6 mRNA and protein in the model group were significantly increased (P<0.05). Compared with the model group, the expression levels of TLR4, NF-κB p65 and IL-6 mRNA and protein in the salazopyridine group and Shaoyaotang groups were significantly decreased (P<0.05). Conclusion:Shaoyaotang can inhibit the development of UC by regulating the expressions of TLR4, NF-κB p65 and IL-6 mRNA and proteins in the TLR4/NF-κB pathway.

Interpretation of the pharmaceutical part of Expert Consensus on the Safe and Rational Use of Aminophylline in Children / 中国实用儿科杂志

Theophylline is one of the most widely prescribed drugs worldwide for the treatment of asthma and chronic obstructive pulmonary disease(COPD),and it has been used clinically for more than 80 years. Due to the many adverse reactions and narrow therapeutic window,theophylline and its derivatives have gradually become the third or fourth options in clinical treatment of asthma,especially after the application of inhaled glucocorticoids and β2-ceptor agonists in asthma with good therapeutic effect. However,with the further elucidation of asthma pathogenesis and the in-depth study of theophylline's mechanism of action,as well as the development of specific drug formulations of theophylline such as sustained-release and controlled-release dosage forms,the therapeutic position of theophylline in asthma treatment has been consolidated and understood in a new way. In this paper,the pharmacology and pharmacokinetic parts of "Expert Consensus on the Safe and Rational Use of Aminophylline in Children" are explained in detail,so as to provide reference for rational application of aminophylline in pediatrics.

Preparation of vincristine loaded low density lipoprotein nanoparticles modified by T7 peptide and evaluation of therapeutic effect on glioma / 药学学报

The purpose of this study was to prepare T7 peptide modified vincristine loaded low density lipoprotein (T7-LDL-VCR) nanoparticles to penetrate through blood brain barrier for targeting the brain tumor cells. Firstly, the low density lipoprotein (LDL) nanoparticles were extracted and separated from human serum by density gradient centrifugation method, and then was loaded into the nanoparticle's lipid core by the dry film method, T7 peptide was covalent modified on the surface of the nanoparticles. T7-LDL-VCR was characterized by particle size, entrapment efficiency and peptide attachment efficiency. The fluorescent probe DiR was used to track the brain biodistribution of T7-LDL-VCR in mice bearing intracranial C6 glioma by means of in vivo imaging. The therapeutic effect of nanoparticles was observed with magnetic resonance imaging (MRI). Finally, relative tumor volume and survival curve were determined in mice. The results showed that the mean size of the prepared T7-LDL-VCR nanoparticle was about 30 nm, encapsulation efficiency was 30.1%, and peptide attachment efficiency was 63.88%. As expected, the prepared preparation has good brain targeting and good effect on the treatment of glioma in mice:the relative tumor volumes of T7-VCR-LDL, LDL-VCR and VCR were 30%, 51.50% and 79.25%, respectively; the median survival time (36 days), which was 2, 1.85 and 1.38 fold higher than that of physiological saline, free VCR and LDL-VCR, respectively. This study suggests that dual modified hposomes possessed a better ability penetrating the blood brain barrier to target the brain tumor with significant antitumor activities.

Current status and prospect of translational medicine in nanotechnology / 药学学报

Nowadays, nanotechnologies have shown wide application foreground in the biomedical field of medicine laboratory tests, drug delivery, gene therapy and bioremediation. However, in recent years, nanomaterials have been labeled poisonous, because of the disputes and misunderstandings of mainstream views on their safety. Besides, for the barriers of technical issues in preparation like: (1) low efficacy (poor PK & PD and low drug loading), (2) high cost (irreproducibility and difficulty in scale up), little of that research has been successfully translated into commercial products. Currently, along with the new theory of "physical damage is the origin of nanotoxicity", biodegradability and biocompatibility of nanomaterials are listed as the basic principle of safe application of nanomaterials. Combining scientific design based on molecular level with precision control of process engineering will provide a new strategy to overcome the core technical challenges. New turning point of translational medicine in nanotechnology may emerge.

Expression of aquaporin-1 in rat pleural mesothelial cells and its specific inhibition by RNA interference in vitro / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The discovery of water channel aquaporins (AQPs) has greatly expanded the understanding of the regulation of the water permeability of biological membranes. Aquaporin-1 (AQP1) may be involved in fluid transport in numerous pathological conditions. The objective of the present study was to examine whether AQP1 is present in cultured rat pleural mesothelial cells (PMCs) and to investigate the specific inhibitory effect of RNA interference (RNAi) on AQP1 expression in PMCs, which may provide a new method for the further studies on the relation between expression of AQP1 in PMCs and pleural fluid removal in vivo.</p><p><b>METHODS</b>PMCs were isolated and cultured from rat pleura. The expression of AQP1 in PMCs was confirmed by immunocytochemical staining and reverse transcriptase-polymerase chain reaction (RT-PCR). Two eukaryotic expression plasmid vectors of short hairpin RNA (shRNA) specific for the AQP1 gene of rat sapien were designed and constructed. The recombinant plasmid vectors were transfected into cultured rat PMCs by cation liposomes. Flow cytometry was used to screen the most effective shRNA at 48 hours after transfection. The expressions of AQP1 mRNA and protein were detected by RT-PCR and Western blotting method at 48 hours after transfection.</p><p><b>RESULTS</b>RT-PCR and immunostaining revealed that AQP1 mRNA and protein were present in cultured rat PMCs. Two effective eukaryotic expression plasmid vectors of shRNA specific for the AQP1 gene were constructed successfully. The levels of the expression of AQP1 were inhibited by 83.45%, 90.93%, respectively, at mRNA level and 41.24%, 67.60%, respectively at protein level by two recombinant plasmids at 48 hours after transfection. The expression of AQP1 in PMCs transfected with plasmid was significantly lower than that of the cells transfected with the control plasmid HK and that of the untransfected cells (P < 0.01). There was no significant difference in AQP1 expression between the control group and the group transfected with AQP1 nonspecific shRNAs (P < 0.05).</p><p><b>CONCLUSIONS</b>The expression of AQP1 was present in rat PMCs. The application of shRNA-AQP1 could markedly inhibit the expression of AQP1 in cultured rat PMCs. The use of RNAi is a promising tool for future research into the mechanisms of pleural fluid in vivo.</p>

Diagnosis and surgical treatment of middle lobe disease of lung: report of 163 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To discuss the principle of diagnosis and surgical treatment of middle lobe diseases of right lung.</p><p><b>METHODS</b>We analysed the clinical data and prognosis of 163 patients who suffered from middle lobe diseases of right lung and received surgical treatment.</p><p><b>RESULTS</b>There were 97 men and 66 women in the group with the ratio 1.5:1, whose age arranged from 13 to 74 years. The shortest course was one week, and the longest 25 years. The average course was 30.3 months. 78 of 163 patients with tumors were malignant (47.9%) and 85 benign (52.1%). The number of the patients below 50 years old was 91 and 81.3% of them were benign, which was very markedly higher than that of the patients with malignant tumors (P < 0.01). The number of the patients above 50 years old was 72 and 84.7% were malignant, which was very markedly higher than that of the patients with benign tumors (P < 0.01); 8 of 11 patients (72.7%, 8/11) who suffered from tuberculosis combined with bronchoactesis. One of this group died from respiratory failure after operation, packed accumulation of fluid between lobes happened in seven cases (4.3%). The survival rate of 1, 3, 5 years of malignant patients at stages I, II were 88.4%, 62.8%, 51.2%, for that at stages III, IV were 76.5%, 41.2%, 14.7%. All of the four patients who received vage-resection, their malignant tumors recurred in one year after operation. No benign lesion recurred in 10 years.</p><p><b>CONCLUSION</b>(1) It should be noticed that nearly half of middle lobe disease were malignant, especially to those whose ages were above 50 years old. (2) When the diagnosis is hard to be confirmed, open-thoracic exploration should be performed in order not to delay the treatment or enlarge the range of lung resection. (3) Most of middle lobe tuberculosis may be combined with bronchoactesis. (4) Setting drainage tube may be useful to decrease the risk of interlobe accumulation of fluid. (5) Vage resection is not suitable for carcinoma of middle lobe of lung.</p>

Retrospective studies on 713 cases chronic obstructive pulmonary disease / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the diagnostic criteria of severity of chronic obstructive pulmonary diseases (COPD), early intervention, and the effect of health education on the relationship between smoking and health.</p><p><b>METHODS</b>Data from 713 remissive COPD patients who had results of pulmonary function test in the past 10 years were reviewed. All patients were classified by correlative diagnostic criteria, and the results were compared with the diagnostic criteria of WHO Global Initiative for chronic obstructive lung disease (GOLD). Other indexes such as history of smoking, quantity of smoking and the rate of giving up smoking were also analyzed.</p><p><b>RESULTS</b>According to the diagnostic criteria set by the Chinese Respiratory College in 1997 and traditional pulmonary function criteria, 339 patients were identified as having severe COPD, taking up 56.0% of all COPD patients; 200 patients were moderate (28.0%); 114 patients were mild (16.0%). FEV(1)/FVC in mild COPD patients was 70.5% +/- 1.1%, higher than the criteria of 70% in GOLD. Three hundred and thirty-five patients were smokers, taking up 46.9% of total patients. In these patients, 312 patients were men (93%) and 23 patients were women (7%). The average smoking history was 32.9 years, and the average quantity of daily smoking was 22. Two hundred sixteen patients had given up smoking which took up 64.5% of all the smokers.</p><p><b>CONCLUSIONS</b>It was debatable that FEV(1)/FVC was decisive criteria for COPD diagnoses by GOLD and the revised diagnostic criteria of Chinese Respiratory College in 2002. It might miss diagnosing a number of COPD patients who having combined ventilatory disturbance or were in earlier stages. Only 15.9% of mild COPD patients had seen a doctor, that indicated a very low rate of early intervention which was disadvantageous for the prevention and cure of COPD. In contrast to the rate of 28.0% when giving up smoking in ordinary people who had received general intervention, the rate of giving up smoking in COPD patients remained 64.5% much higher and was dissatisfactory. Health education should be improved to include measures to give up smoking.</p>
