Construction of SARS-CoV-2 receptor binding domain molecular probe and its application in the isolation of neutralizing antibodies / 中国热带医学

@#Abstract: Objective　To construct SARS-CoV-2 receptor binding domain molecular probe for monoclonal memory B cell sorting and obtain RBD specific neutralizing antibodies from peripheral blood mononuclear cells (PBMCs) of COVID-19 convalescents by single-cell sorting. Methods　The SARS-CoV-2 RBD sequence was downloaded from GenBank, and the Avi tag and 6-histidine tags were added at the C-terminal. After codon optimization, it was chemically synthesized, cloned into the pDRVI1.0 vector, expressed after transfection of 293F cells, and biotinylated consequently. RBD-specific B cells were sorted out with this probe1 from the PBMCs of convalescents recovered from COVID-19. After B cells were lysed, the variable regions of heavy chain and light chain were amplified, cloned into the antibody expression vector, and transfected into 293F cells to express the antibody. Then the antibody was purified from the supernatant using protein A column and SARS-CoV-2 pseudovirus was used to test their neutralizing activity. Results　RBD-Avi probe was produced and successfully biotinylated sequentially with an efficiency of 30%-50%. Western blot analysis revealed that the biotinylated probe was recognized by the antibodies purified from COVID-19 convalescent plasma. Using this probe, 7 and 16 RBD-specific memory B cells were successfully isolated from the PBMCs of two convalescent individuals, accounting for 0.24% and 0.17% of the total cell population, respectively. After amplifying the variable regions of antibody heavy and light chains from the lysed B cells, 7 and 12 pairs of antibody heavy-light chains were obtained. A total of 16 antibodies were expressed in the convalescent individuals, and most of the purified antibodies showed neutralizing activity against the pseudovirus, with IC50 values of 6 antibodies below 1 μg/mL. The IC50 values of XJ-A9 and SCF-F1 against the wild-type pseudovirus were 0.07 μg/mL and 0.35 μg/mL, respectively. Conclusion　The SARS-CoV-2 RBD molecular probe constructed in this study has good antigenicity, and the isolated antibodies present neutralizing activity against wild-type SARS-CoV-2 pseudovirus.

Innovative Teaching of "Doctor-patient" Friendly Model for Diabetes from the Perspective of Deep Blended Learning / 中国医学伦理学

The teaching of diabetes has always been the focus and difficulty of clinical internal science teaching. How to skillfully integrate theoretical knowledge into clinical practice and help students deeply master medical knowledge and clinical skills is a topic that clinical teaching teachers are considering. Under the background of analyzing the concept and connotation of deep blended learning, this paper constructed the diabetes "doctor-patient" friendly model teaching process in the perspective of deep blended learning from the three stages of "learning situation analysis and independent learning" in the early stage, "ability improvement and in-depth research" in the middle stage, and "reflection and ability expansion" in the later stage. This paper expounded the positive role of the "doctor-patient" friendly model of diabetes in clinical teaching from three main aspects: improving the integration effect of theory and practice, fully meeting students’ learning needs, and increasing the connection between doctors, patients, and students.

Structure-guided discovery of potent and oral soluble epoxide hydrolase inhibitors for the treatment of neuropathic pain

Soluble epoxide hydrolase (sEH) is related to arachidonic acid cascade and is over-expressed in a variety of diseases, making sEH an attractive target for the treatment of pain as well as inflammatory-related diseases. A new series of memantyl urea derivatives as potent sEH inhibitors was obtained using our previous reported compound 4 as lead compound. A preferential modification of piperidinyl to 3-carbamoyl piperidinyl was identified for this series via structure-based rational drug design. Compound A20 exhibited moderate percentage plasma protein binding (88.6%) and better metabolic stability in vitro. After oral administration, the bioavailability of A20 was 28.6%. Acute toxicity test showed that A20 was well tolerated and there was no adverse event encountered at dose of 6.0 g/kg. Inhibitor A20 also displayed robust analgesic effect in vivo and dose-dependently attenuated neuropathic pain in rat model induced by spared nerve injury, which was better than gabapentin and sEH inhibitor (±)-EC-5026. In one word, the oral administration of A20 significantly alleviated pain and improved the health status of the rats, demonstrating that A20 was a promising candidate to be further evaluated for the treatment of neuropathic pain.

Preparation and characterization of fenugreek leaf flavonoids and their protective effects against oxidative damage to hepatocytes / 中国中药杂志

The present study investigated the main components of fenugreek(Trigonella foenum-graecum L.) leaf flavonoids(FLFs) and their antioxidant activity. FLFs were prepared and enriched by solvent extraction, and the flavonoids were characterized by high-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(HPLC-Q-TOF-MS/MS). The protective effect of FLFs against H_2O_2-induced stress damage to L02 hepatocytes was also investigated. Firstly, the cell viability was measured by MTT assay. The oxidative stress injury model was induced by H_2O_2 in L02 cells. The release of lactate dehydrogenase(LDH), the content of reduced glutathione(GSH) and malondialdehyde(MDA), and the activities of superoxide dismutase(SOD) and catalase(CAT) were measured by assay kits. Hoechst fluorescence staining was performed to observe the cell apoptosis. The expression levels of c-Jun N-terminal kinase(JNK), extracellular signal-regulated kinase 1/2(ERK1/2), nuclear factor erythroid-2 related factor 2(Nrf2), heme oxygenase 1(HO-1), and their phosphorylated proteins were detected by Western blot. Based on the MS fragment ion information and data in databases, FLFs contained eight flavonoids with quercetin and kaempferol as the main aglycons. The cell viabi-lity assay revealed that as compared with the conditions in the H_2O_2 treatment group, 3.125-25 μg·mL~(-1) FLFs could increase the viability of L02 cells, reduce LDH release and MDA content in a dose-dependent manner, potentiate the activities of SOD, CAT, and GSH, decrease the phosphorylation of JNK and ERK1/2 proteins, and up-regulate the expression of Nrf2 and HO-1. The results of fluorescence staining showed that the nucleus of the H_2O_2 treatment group showed concentrated and dense strong blue fluorescence, while the blue fluorescence intensity of the FLFs group decreased significantly. FLFs showed a protective effect against H_2O_2-induced oxidative damage in L02 cells, and the underlying mechanism is associated with the enhancement of cell capability in clearing oxygen free radicals and the inhibition of apoptosis by the activation of the MAPKs/Nrf2/HO-1 signaling pathway. The antioxidant effect of fenugreek leaf is related to its rich flavonoids.

Active components of Descurainia sophia improve lung permeability in rats with allergic asthma by regulating airway inflammation and epithelial damage / 中国中药杂志

The present study investigated the effect of active components of Descurainia sophia on allergic asthma and explored the underlying mechanism. SD male rats were randomly divided into a normal group(NC), a model group(M), a D. sophia decoction group(DS), a D. sophia fatty oil group(FO), a D. sophia flavonoid glycoside group(FG), a D. sophia oligosaccharide group(Oli), and a positive drug dexamethasone group(Y). The allergic asthma model was induced in rats by intraperitoneal injection of ovalbumin(OVA) and aluminum hydroxide gel adjuvant(sensitization) and atomization of OVA solution(excitation). After modeling, asthma-related indicators, tracheal phenol red excretion, inflammatory cell levels in the peripheral blood, lung permeability index(LPI), and oxygenation index(OI) of rats were detected. The pathological changes of lung tissues were observed by HE staining. Enzyme-linked immunosorbent assay(ELISA) was used to detect the content of inflammatory factors immunoglobulin E(IgE), interleukin-4(IL-4), and interferon-γ(IFN-γ) in the bronchoalveolar lavage fluid(BALF) and the content of endothelin-1(ET-1) and angiotensin-converting enzyme(ACE) in lung tissue homogenate. The serum content of nitric oxide(NO) was detected by colorimetry. Western blot was employed to determine the protein expression of Toll-like receptor 4(TLR4), nuclear factor κB-p65(NF-κB-p65), phosphorylated NF-κB-p65(p-NF-κB-p65), myosin light chain kinase(MLCK), vascular endothelial cadherin(VE cadherin), connexin 43, and claudin 5, and the mechanism of active components of D. sophia on allergic asthma was explored. As revealed by the results, the M group showed extensive infiltration of inflammatory cells around the bronchus of the lung tissues of the allergic asthma rats, thickened bronchial wall, severely deformed alveolar structure, increased number of wheezes, the content of IgE, IL-4, ET-1, and ACE, inflammatory cells, and LPI, and reduced latency of asthma, tracheal phenol red excretion, IFN-γ, NO content, and OI. After the intervention of the active components of D. sophia, the DS, FO, FG, Oli, and Y groups showed improved asthma-related indicators, tracheal phenol red excretion, and lung tissue lesions in allergic asthma rats, and the effects in the FO and Oli groups were superior. The content of inflammatory factors in BALF was recovered in the DS, FO, and Y groups and the FG and Oli groups. The number of inflammatory cells in rats was reduced in the DS and FO groups, and the FG, Oli, and Y groups to varying degrees, and the effect in the FO group was superior. DS, FO, Oli, and Y reduced ET-1, ACE, and LPI and increased NO and OI. FG recovered NO, ET-1, ACE, LPI, and OI to improve lung epithelial damage and permeability. Further investigation of inflammation-related TLR4/NF-κB pathways, MLCK, and related skeleton protein levels showed that TLR4, NF-κB-p65, p-NF-κB-p65, and MLCK levels were increased, and VE cadherin, connexin 43, and claudin 5 were reduced in the M group. DS, FO, FG, Oli, and Y could reduce the protein expression related to the TLR4 pathway to varying degrees, and regulate the protein expression of MLCK, VE cadherin, connexin 43, and claudin 5. It is inferred that the active components of D. sophia improve lung permeability in rats with allergic asthma presumedly by regulating the TLR4/NF-κB signaling pathway to improve airway inflammation, mediating MLCK and connexin, and regulating epithelial damage.

Adherence to adjuvant with therapy imatinib in patients with gastrointestinal stromal tumor: a national multi-center cross-sectional study / 中华胃肠外科杂志

Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.

Early recognition and treatment of intravenous immunoglobulin unresponsive patients with Kawasaki disease / 国际儿科学杂志

The cause of Kawasaki disease(KD) remains unclear.Coronary artery lesions (CAL)can occur in 20％ ～25％ children with untreated KD.The usage of high-dose intravenous immunoglobulin(IVIG) has reduced the incidence of CAL,but some patients will not respond to IVIG and have a higher incidence of CAL.Early recognition of IVIG unresponsiveness patients with KD may help physicians to adjust treatment and to improve the prognosis.Factors related to IVIG unresponsive including clinical characteristics and laboratory findings.Clinical scoring systems were also used to predict IVIG unresponsive KD patients.But there was a lack of a better scoring system or method that have been validated by clinicians.Retreatment with IVIG was a widely accepted therapy in IVIG unresponsive KD patients by now.Using effective agents such as corticosteroids and TNF-α antagonists in a timely way may play an important role to reduce the incidence of CAL in IVIG unresponsive KD patients.But there is no standard treatment protocol for IVIG unresponsive KD currently.This paper reviewed the progress in early recognition and treatment of IVIG unresponsive KD patients to provide reference for clinicians.

Influence of amlodipine besylate combined metoprolol on serum inflammatory factor levels and cardiac function in aged patients with EH complicated CHF / 心血管康复医学杂志

Objective:To explore influence of amlodipine besylate tablet combined metoprolol on serum inflammatory factor levels and cardiac function in aged patients with essential hypertension(EH)complicated chronic heart failure(CHF).Methods:A total of 98 aged EH+CHF patients treated in our hospital from Jan 2014 to Oct 2015 were se-lected.Patients were randomly and equally divided into metoprolol group(received metoprolol based on routine treatment)and combined treatment group(received amlodipine besylate tablet based on metoprolol group),both groups were treated for six months.Serum levels of interleukin(IL)-1,IL-6 and tumor necrosis factor(TNF)-α, left ventricular end-diastolic dimension(LVEDd),left ventricular end-systolic dimension(LVESd)and left ventric-ular ejection fraction(LVEF)before and six months after treatment,and therapeutic effect were measured and compared between two groups.Results:Compared with before treatment,after six-month treatment,there were significant reductions in serum levels of IL-1,IL-6,TNF-α,LVEDd and LVESd,and significant rise in LVEF in two groups,P=0.001 all;compared with metoprolol group after six-month treatment,there were significant reduc-tions in serum levels of IL-1[(16.21 ± 1.45)ng/L vs.(12.34 ± 1.32)ng/L],IL-6[(46.21 ± 5.32)ng/L vs. (36.42 ± 4.51)ng/L],TNF-α[(23.12 ± 2.14)ng/L vs.(19.25 ± 2.41)ng/L],LVEDd[(51.68 ± 4.74)mm vs. (42.31 ± 4.25)mm]and LVESd[(46.27 ± 4.78)mm vs.(39.06 ± 4.35)mm],and significant rise in LVEF [(43.26 ± 4.37)% vs.(52.95 ± 5.18)%]in combined treatment group,P=0.001 all.Total effective rate of com-bined treatment group was significantly higher than that of metoprolol group(93.88% vs.79.59%),P= 0.037. There was no significant difference in incidence rate of adverse reactions between two groups,P=0.505. Conclu-sion:Amlodipine besylate combined metoprolol possesses significant therapeutic effect on aged EH + CHF patients, which may reduce serum inflammatory factor levels,relieve ventricular remodeling and improve cardiac function.

Analysis of subfoveal choroidal thickness and macular ganglion cell layer thickness in hyperopia anisometropic amblyopic eyes / 上海交通大学学报（医学版）

Objective· To analyze and compare the subfoveal choroidal thickness and macular ganglion cell layer (MGCL) thickness in hyperopia anisometropic amblyopic children between the amblyopic eyes and the fellow eyes.Methods · The subfoveal choroidal thickness and the MGCL thickness were measured by enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT) in 63 hyperopic anisometropic amblyopic children.The value of subfoveal choroidal thickness and the MGCL thickness were compared between the amblyopic eyes and the fellow eyes.The average thickness of the eyes between the different types was compared using the paired t test.Results· Mean subfoveal choroidal thickness was (321.83±12.74) μm and (316.78±18.76) μm respectively in amblyopic and fellow eyes (P 0.182).Mean MGCL thickness was (83.78±4.81) μm in amblyopic eyes and (83.26±4.17) μm in the fellow eyes (P=0.223).Conclusion· Mean subfoveal choroidal thickness and MGCL thickness were not statistically significant between hyperopic anisometropic amblyopic eyes and normal fellow eyes.

Research progress on the role of histone deacetylase 9 in tumors / 中国肿瘤临床

Histone deacetylase 9 (HDAC9) belongs to the IIa subtype of HDACs. It is responsible for changing the structure of chromo-somes and regulating the transcription of genes by catalyzing the deacetylation of H3, H4, and non-histone proteins in vivo. Emerging studies have demonstrated that HDAC9 is closely related to tumors, but their expression and function in different tumors is not the same. This could ultimately lead to the opposite effect of promoting or suppressing tumorigenesis; unfortunately, the mechanisms are not clear. Recently, epigenetic treatment with HDAC deacetylases inhibitors (HDACIs) has become a hot topic and the development of selective HDACIs in combination with chemotherapy, radiotherapy, and immunotherapy has gained traction. However, studies target-ing HDAC9 are limited. This review summarizes the recent studies about HDAC9 in tumors.
