ABSTRACT

Neutralizing antibodies (NAbs) can prevent and treat infections caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, continuously emerging variants, such as Omicron, have significantly reduced the potency of most known NAbs. The selection of NAbs with broad neutralizing activities and the identification of conserved critical epitopes are still urgently needed. Here, we identified an extremely potent antibody (55A8) by single B-cell sorting from convalescent SARS-CoV-2-infected patients that recognized the receptor-binding domain (RBD) in the SARS-CoV-2 spike (S) protein. 55A8 could bind to wild-type SARS-CoV-2, Omicron BA.1 and Omicron BA.2 simultaneously with 58G6, a NAb previously identified by our group. Importantly, an antibody cocktail containing 55A8 and 58G6 (2-cocktail) showed synergetic neutralizing activity with a half-maximal inhibitory concentration (IC50) in the picomolar range in vitro and prophylactic efficacy in hamsters challenged with Omicron (BA.1) through intranasal delivery at an extraordinarily low dosage (25 g of each antibody daily) at 3 days post-infection. Structural analysis by cryo-electron microscopy (cryo-EM) revealed that 55A8 is a Class III NAb that recognizes a highly conserved epitope. It could block angiotensin-converting enzyme 2 (ACE2) binding to the RBD in the S protein trimer via steric hindrance. The epitopes in the RBD recognized by 55A8 and 58G6 were found to be different and complementary, which could explain the synergetic mechanism of these two NAbs. Our findings not only provide a potential antibody cocktail for clinical use against infection with current SARS-CoV-2 strains and future variants but also identify critical epitope information for the development of better antiviral agents.

ABSTRACT

Following Delta, Omicron variant triggered a new wave of SARS-CoV-2 infection globally, adaptive evolution of the virus may not stop, the development of broad-spectrum antivirals is still urgent. We previously developed two hetero-bivalent nanobodies with potent neutralization against original WT SARS-CoV-2, termed aRBD-2-5 and aRBD-2-7, by fusing aRBD-2 with aRBD-5 or aRBD-7, respectively. Here, we resolved crystal structures of these nanobodies in complex with RBD, and found the epitope of aRBD-2 differs from that of aRBD-5, aRBD-7. aRBD-2 binds to a conserved epitope which renders its binding activity to all variants of concern (VOCs) including Omicron. Interestingly, although monovalent aRBD-5 and aRBD-7 lost binding to some variants, they effectively improved the overall affinity when transformed into the hetero-bivalent form after being fused with aRBD-2. Consistent with the high binding affinities, aRBD-2-5-Fc and aRBD-2-7-Fc exhibited ultra-potent neutralization to all five VOCs; particularly, aRBD-2-5-Fc neutralized authentic virus of Beta, Delta and Omicron with the IC50of 5.98[~]9.65 ng/mL or 54.3[~]87.6 pM. Importantly, aRBD-2-5-Fc provided in vivo prophylactic protection for mice against WT and mouse-adapted SARS-CoV-2, and provided full protection against Omicron in hamster model when administrated either prophylactically or therapeutically. Taken together, we found a conserved epitope on RBD, and hetero-bivalent nanobodies had increased affinity for VOCs over its monovalent form, and provided potent and broad-spectrum protection both in vitro and in vivo against all tested major variants, and potentially future emerging variants. Our strategy provides a new solution in the development of therapeutic antibodies for COVID-19 caused by newly emergent VOCs.

ABSTRACT

SARS-CoV-2 has infected more than 400 million people around the globe and caused millions of deaths. Since its identification in November 2021, Omicron, a highly transmissible variant, has become the dominant variant in most countries. Omicrons highly mutated spike protein, the main target of vaccine development, significantly compromises the immune protection from current vaccination. We develop an mRNA vaccine (SOmicron-6P) based on an Omicron-specific sequence. In mice, SOmicron-6P shows superior neutralizing antibodies inducing abilities to a clinically approved inactivated virus vaccine, a clinically approved protein subunit vaccine, and an mRNA vaccine (SWT-2P) with the same sequence of BNT162b2 RNA. Significantly, SOmicron-6P induces a 14.4[~]27.7-fold and a 28.3[~]50.3-fold increase of neutralizing activity against the pseudovirus of Omicron and authentic Omicron compared to SWT-2P, respectively. In addition, two doses SOmicron-6P significantly protects Syrian hamsters against challenge with SARS-CoV-2 Omicron variant and elicits high titers of nAbs in a dose-dependent manner in macaques. Our results suggest that SOmicron-6P offers advantages over current vaccines, and it will be helpful for those with weak immunity.

ABSTRACT

Fusion with host cell membrane is the main mechanism of infection of SARS-CoV-2. Here, we propose a new strategy to double block SARS-CoV-2 membrane fusion by using Harringtonine (HT), a small-molecule antagonist. By using cell membrane chromatography (CMC), we found that HT specifically targeted the SARS-CoV-2 S protein and host cell TMPRSS2, and then confirmed that HT can inhibit pseudotyped virus membrane fusion. Furthermore, HT successfully blocked SARS-CoV-2 infection, especially in the delta and Omicron mutant. Since HT is a small-molecule antagonist, it is minimally affected by the continuous variation of SARS-CoV-2. Our findings show that HT is a potential small-molecule antagonist with a new mechanism of action against SARS-CoV-2 infection, and thus HT mainly targets the S protein, and thus, greatly reduces the damage of the S proteins autotoxicity to the organ system, has promising advantages in the clinical treatment of COVID-19.

ABSTRACT

Coronavirus disease 2019 (COVID-19), which is triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, continues to threaten global public health. Developing a vaccine that only requires single immunization but provides long-term protection for the prevention and control of COVID-19 is important. Here, we developed an adeno-associated virus (AAV)-based vaccine expressing a stable receptor-binding domain (SRBD) protein. The vaccine requires only a single shot but provides effective neutralizing antibodies (NAbs) over 598 days in rhesus macaques (Macaca mulatta). Importantly, our results showed that the NAbs were kept in high level and long lasting against authentic wild-type SARS-CoV-2, Beta, Delta and Omicron variants using plaque reduction neutralization test. Of note, although we detected pre-existing AAV2/9 antibodies before immunization, the vaccine still induced high and effective NAbs against COVID-19 in rhesus macaques. AAV-SRBD immune serum also efficiently inhibited the binding of ACE2 with RBD in the SARS-CoV-2 B.1.1.7 (Alpha), B.1.351 (Beta), P.1/P.2 (Gamma), B.1.617.2 (Delta), B.1.617.1/3(Kappa), and C.37 (Lambda) variants. Thus, these data suggest that the vaccine has great potential to prevent the spread of SARS-CoV-2.

ABSTRACT

Accumulating mutations in the SARS-CoV-2 Spike (S) protein can increase the possibility of immune escape, challenging the present COVID-19 prophylaxis and clinical interventions. Here, 3 receptor binding domain (RBD) specific monoclonal antibodies (mAbs), 58G6, 510A5 and 13G9, with high neutralizing potency blocking authentic SARS-CoV-2 virus displayed remarkable efficacy against authentic B.1.351 virus. Each of these 3 mAbs in combination with one neutralizing Ab recognizing non-competing epitope exhibited synergistic effect against authentic SARS-CoV-2 virus. Surprisingly, structural analysis revealed that 58G6 and 13G9, encoded by the IGHV1-58 and the IGKV3-20 germline genes, both recognized the steric region S470-495 on the RBD, overlapping the E484K mutation presented in B.1.351. Also, 58G6 directly bound to another region S450-458 in the RBD. Significantly, 58G6 and 510A5 both demonstrated prophylactic efficacy against authentic SARS-CoV-2 and B.1.351 viruses in the transgenic mice expressing human ACE2 (hACE2), protecting weight loss and reducing virus loads. These 2 ultrapotent neutralizing Abs can be promising candidates to fulfill the urgent needs for the prolonged COVID-19 pandemic.

ABSTRACT

@#Objective    To compare the perioperative results of hybrid coronary revascularization (HCR), off-pump coronary artery bypass (OPCAB) and percutaneous coronary intervention (PCI) in elderly patients with three-vessel coronary artery disease involving left anterior descending (LAD) branch and explores the safety of surgery. Methods    We prospectively enrolled patients with coronary heart disease over 65 years who were admitted to General Hospital of People’s Liberation Army from January 2018 to September 2019. Coronary angiography results were all three-vessel lesions involving the anterior descending artery. After preoperative examination and assessment by the cardiovascular team, all patients were suitable for OPCAB or PCI treatment. According to the patient’s preference, HCR, OPCAB or PCI were performed. The preoperative baseline data and perioperative results were collected, and SPSS 22.0 was used for statistical analysis. Results    A total of 110 patients met the criteria and were included in the study, 28 in the HCR group, 45 in the OPCAB group, and 37 in the PCI group, with an average age of 71.4±5.6 years. There was no statistical difference in the preoperative baseline data of patients among the three groups. The intubation time (P=0.039), perioperative drainage volume (P<0.001), blood transfusion (P=0.021) in the HCR group were lower than those in the OPCAB group. There was no statistical difference in the main organ adverse events (MOAE, P=0.096) and in-hospital mortality (P=0.784) among the three groups of patients. The use of antibiotics in the PCI group was significantly lower than the other two groups (P<0.001). Conclusion    HCR combines the advantage of CABG and PCI including proved long-term patency rate with left internal mammary artery-LAD grafting, less trauma and superior long-term patency with PCI in non-LAD territory. Compared with OPCAB and PCI, there is no increase in perioperative major organ adverse events and in-hospital mortality. It is a safe and reliable minimally invasive myocardial revascularization technique for elderly patients with three-vessel coronary artery disease involving the anterior descending artery.

ABSTRACT

Currently, there are no approved specific antiviral agents for 2019 novel coronavirus disease (COVID-19). In this study, ten severe patients confirmed by real-time viral RNA test were enrolled prospectively. One dose of 200 mL convalescent plasma (CP) derived from recently recovered donors with the neutralizing antibody titers above 1:640 was transfused to the patients as an addition to maximal supportive care and antiviral agents. The primary endpoint was the safety of CP transfusion. The second endpoints were the improvement of clinical symptoms and laboratory parameters within 3 days after CP transfusion. The median time from onset of illness to CP transfusion was 16.5 days. After CP transfusion, the level of neutralizing antibody increased rapidly up to 1:640 in five cases, while that of the other four cases maintained at a high level (1:640). The clinical symptoms were significantly improved along with increase of oxyhemoglobin saturation within 3 days. Several parameters tended to improve as compared to pre-transfusion, including increased lymphocyte counts (0.65x109/L vs. 0.76x109/L) and decreased C-reactive protein (55.98 mg/L vs. 18.13 mg/L). Radiological examinations showed varying degrees of absorption of lung lesionswithin 7 days. The viral load was undetectable after transfusion in seven patients who had previous viremia. No severe adverse effects were observed. This study showed CP therapy was welltolerated and could potentially improve the clinical outcomes through neutralizing viremia in severe COVID-19 cases. The optimal dose and time point, as well as the clinical benefit of CP therapy, needs further investigation in larger well-controlled trials. Significance StatementCOVID-19 is currently a big threat to global health. However, no specific antiviral agents are available for its treatment. In this work, we explored the feasibility of convalescent plasma (CP) transfusion to rescue severe patients. The results from 10 severe adult cases showed that one dose (200 mL) of CP was welltolerated and could significantly increase or maintain the neutralizing antibodies at a high level, leading to disappearance of viremia in 7 days. Meanwhile, clinical symptoms and paraclinical criteria rapidly improved within 3 days. Radiological examination showed varying degrees of absorption of lung lesions within 7 days. These results indicate that CP can serve as a promising rescue option for severe COVID-19 while the randomized trial is warranted.

ABSTRACT

Objective:To explore the epidemic situation and brucellosis in key occupational populations of brucellosis monitoring sites in Jiangsu Province, and provide a basis for development of prevention and control strategies against brucellosis.Methods:From 2013 to 2017, according to the requirements of the "National Brucella Surveillance Programme", two brucellosis monitoring sites in Yixing City of Wuxi and Huaiyin District of Huai'an, Jiangsu Province were established to monitor brucellosis. Brucellosis epidemic data were collected and analyzed of the two monitoring sites in Yixing City and Huaiyin District from 2013 to 2017 (data were from Jiangsu Provincial Legal Infectious Disease Reporting System). Blood samples were collected from the general occupational populations (health check-up population) and the key occupational populations (people engaged in livestock trading, livestock slaughtering, and the fur, milk and meat processing) in the monitoring sites. Tiger red plate agglutination test (RBPT) and serum tube agglutination test (SAT) were used for serological examination. Results:From 2013 to 2017, a total of 18 cases of brucellosis were reported at the two monitoring sites in Yixing City and Huaiyin District, Jiangsu Province, including 13 males and 5 females, with a male to female sex ratio of 2.6∶1.0; the age of onset was mainly 35 - 64 years, accounting for 72.22% (13/18); the time of onset was mainly from January to June, accounting for 94.44% (17/18); and the occupational distribution was mainly farmers, accounting for 77.78% (14/18); there was no epidemic and outbreaks of brucellosis. A general occupational populations survey was conducted in 17 743 cases, serological tests were negative, no infection and no signs and symptoms were found in the two monitoring sites. In 2013 - 2017, a total of 113 cases of serological tests were positive in the key occupational populations of brucellosis in Jiangsu Province, with a positive rate of 7.83% (113/1 444), and the overall trend was downward year by year ( t = 6.463, P < 0.05). Among them, the positive rates in Yixing City and Huaiyin District were 11.79% (106/899) and 1.28% (7/545), respectively. The difference between different regions was statistically significant (χ 2 = 51.926, P < 0.01). The positive rates of occupational groups engaged in livestock trading, livestock slaughtering, and the fur, milk and meat processing were 5.10% (20/392), 9.74% (49/503), and 8.01% (44/549), respectively. The differences were statistically significant between different occupations (χ 2 = 6.618, P < 0.05); and the positive rates of livestock slaughtering occupations and the fur, milk and meat processing occupations were higher than that of livestock trading occupations ( P < 0.05). Conclusions:The positive rate of brucellosis in key occupational populations has showed a general downward trend, the livestock slaughtering occupations and the fur, milk and meat processing occupations are more susceptible to Brucella infection. It is still necessary to strengthen the health education for the key occupational populations of brucellosis and inspection and quarantine work for prevention of the epidemic of brucellosis in humans.

ABSTRACT

OBJECTIVE@#To compare the mid- and long-term outcomes of patients receiving mitral valve replacement through robotically assisted and conventional median sternotomy approach.@*METHODS@#The data of 47 patients who underwent da Vinci robotic mitral valve replacement in our hospital between January, 2007 and December, 2015 were collected retrospectively (robotic group). From a total of 286 patients undergoing mitral valve replacement through the median thoracotomy approach between March, 2002 and June, 2014, 47 patients were selected as the median sternotomy group for matching with the robotic group at a 1:1 ratio. The perioperative data and follow-up data of the patients were collected, and the quality of life (QOL) of the patients at 30 days and 6 months was evaluated using the Quality of Life Short Form Survey (SF-12). The time of returning to work postoperatively and the patients' satisfaction with the surgical incision were compared between the two groups.@*RESULTS@#All the patients in both groups completed mitral valve replacement successfully, and no death occurred during the operation. In the robotic group, only one patient experienced postoperative complication (pleural effusion); in median sternotomy group, one patient received a secondary thoracotomy for management of bleeding resulting from excessive postoperative drainage, and one patient died of septic shock after the operation. The volume of postoperative drainage, postoperative monitoring time, ventilation time, and postoperative hospital stay were significantly smaller or shorter in the robotic group than in the thoracotomy group (@*CONCLUSIONS@#Robotically assisted mitral valve replacement is safe and reliable. Compared with the median sternotomy approach, the robotic approach is less invasive and promotes faster postoperative recovery of the patients, who have better satisfaction with the quality of life and wound recovery.

ABSTRACT

OBJECTIVE: To study improvement effects of Panax notoginsenoside(PNS) on cisplatin-induced renal injury model rats and its effects on related factors. METHODS: Totally 72 SD rats were randomly divided into blank group, model group, positive drug group and PNS low-dose, medium-dose, high-dose groups, with 12 rats in each group. Except for blank group, other groups were given cisplatin via tail vein (3 mg/kg×4 times) to establish renal injury model. Since the first day after the first injection of cisplatin, positive group was given anfostine solution intraperitoneally (1.0 mg/kg); PNS groups were given PNS solution intraperitoneally (15.63, 31.35, 62.70 mg/kg); blank group and model groups were given constant volume of normal saline 0.2 mL, for consecutive 60 d. The 24 h urine of rats was collected; the contents of β-N-acetylaminoglycosidase(NAG) and 24 h urine protein (Upro/24 h) were detected; the serum contents of Scr and BUN were detected. mRNA and protein expression of CTGF, TGF-β1, Col-1, TIMP-1 and PAI-1 in renal tissue were determined by RT-PCR and immunohistochemistry respectively. RESULTS: Compared with blank group, the contents of NAG and Upro/24 h in urine, serum contents of Scr and BUN, mRNA and protein expression levels of CTGF, TGF-β1, Col-1, TIMP-1 and PAI-1 in renal tissue were increased significantly (P<0.05). Compared with model group, the contents of above urine and serum biochemical indicators were decreased significantly in PNS groups; mRNA expression of CTGF and TGF-β1 and protein expression of CTGF, TGF-β1, Col-1 and TIMP-1 in renal tissue of rats in PNS groups, mRNA expression of Col-1 in PNS high-dose group, and mRNA expression of TIMP-1 and protein expression of PAI-1 in PNS medium-dose and high-dose groups were decreased significantly (P<0.05). Compared with positive group, the contents of NAG and Upro/24 h in urine were decreased significantly in PNS medium-dose and high-dose groups (P<0.05). CONCLUSIONS: PNS can effectively improve the renal function of cisplatin-induced renal injury model rats, and relieve cisplatin-induced renal fibrosis by decreasing the expression of renal fibrosis related factors as CTGF, TGF-β1, Col-1, TIMP-1 and PAI-1 in renal tissue.

ABSTRACT

Objective To explorer effect of integrated traditional chinese and western medicine on hyperthyroidism and on blood glucose metabolism disorder. Methods 70 cases of patients with hyperthyroidism during March 2014 to March 2016 were randomly divided into two groups with 35 cases respectively ,and control group were treated with propylthiouracil,while observation group were treated with traditional chinese medicine on the basis of the control group.Before and after treatment,serum thyroid stimulating hormone(TSH), triiodothyronine(FT3), thyroxine(FT4 ) and fasting plasma glucose (FPG) , 2 hours postprandial blood glucose(2hPG)were detected respectively,the curative effect and adverse reactions were observed. Results After treatment,the levels of TSH,FT3 and FT4 of the both two groups were significantly ameliorative (P<0.05),and FT3 ,FT4 of the observation group were significantly more ameliorative than the control group (P<0.05).The levels of FPG,2hPG of two groups were significantly depressed (P<0.05),and those of the observation group were significantly lower than those of the control group (P<0.05).The clinical effective rate of the observation group was significantly higher than those of the control group (P<0.05).Adverse reactions of two groups were not significantly different. Conclusion The treatment of hyperthyroidism with traditional chinese and western medicine can significantly improve the clinical curative effect and regulate the blood glucose metabolism, and the safety is high.

ABSTRACT

Objective:To study the effects of panax notoginsenosides on the proliferation and oxidation indices of cisplatin-induced nephroxicity in HK-2 cells. Methods:HK-2 cells were cultured in vitro till the number was up to 1 × 106/ml. The cells were inoculated in 96-well culture plate and randomly divided into six groups:normal saline ( NS) group,the model group, the positive control group and the high dose group , medium dose group and low dose group of panax notoginsenosides ( PNS) . The nephroxicity model was dupli-cated with the addition of cisplatin (the final concentration was 6. 25μg·L-1). The model group, positive control group and the three panax notoginsenosides groups was treated with saline solutions, amifostine, panax notoginsenosides at the dose of 100,50 and 25 mg· L-1 , respectively. The cell viability was detected with an MTT method, the content of MDA and the activity of SOD, GSH-PX and LDH were measured and the cell structure was observed. DCFH-DA was used as the fluorescence probe to detect the level of ROS by a fluorescence microplate reader. Results:Compared with those in the model group, the cell viability and the activity of SOD and GSH-PX in the three PNS groups and the positive control group significantly increased (P<0. 05);the content of MDA, the level of ROS and the activity of LDH significantly decreased (P<0. 05); the cell structure was significantly improved. Conclusion: PNS can pro-mote the proliferation of HK-2 cells in vitro, and improve the biochemical parameters and enzyme levels. The results suggest that PNS has a protective effect on HK-2 cell,and the protective mechanisms may be related with its antioxidant effect.

ABSTRACT

Objective To investigate the efficacy of tamsulosin hydrochloride combined with clear stasis and kidney decoction on chronic prostatitis and its influence on immune function and urine flow rate. Methods In this study, 115 patients with chronic prostatitis were selected and divided into treatment group (58 patients) and control group (57 patients) according to the random number table method.The control group used tamsulosin hydrochloride treatment, and the treatment group was treated with clear stasis and kidney decoction on the basis of the control group.The patients in two groups were treated continuously for 4 weeks. The clinical efficacy was evaluated and compared, the changes of immune function, free flow rate and maximum urinary flow rate were measured and compared between two groups.Results The total effective rate of the treatment group was significantly higher than that of the control group:94.83%(55/58)vs.78.95%(45/57)P<0.05.The levels of IgA and IgG before treatment in two groups had no significant differences(P>0.05).After treatment, the levels of IgA and IgG in two groups significantly decreased compared with those before treatment(P<0.05), and the levels of IgA and IgG in treatment group were significantly lower than those in control group(P<0.05).The levels of NIH-CPSI scores and WBC before treatment in two groups had no significant differences (P > 0.05). After treatment, The levels of NIH-CPSI scores and WBC significantly decreased compared with those before treatment(P<0.01), and the levels of NIH-CPSI scores and WBC in treatment group were significantly lower than those in control group (P < 0.01). After treatment lecithin (+- ++) and (+++- +++++) in treatment group was 3,55 cases, in control group was 12,45 cases, and there was significant difference (χ2= 6.392, P = 0.011). Before treatment, the levels of free urine flow rate, maximum urine flow rate, maximum urine flow rate time and residual urine volume in two groups had no significant differences(P>0.05). After treatment, the levels of free urine flow rate and maximum urine flow rate in two groups significantly increased, the levels of maximum urine flow rate time and residual urine volume in two groups significantly decreased, and there were significantly differences compared those before treatment (P < 0.05).The levels of free urine flow rate, maximum urine flow rate, maximum urine flow rate time and residual urine volume between two groups had significant differences after treatment(P<0.01).The adverse reaction rate in control group and treatment group was 3.51%(2/57),6.90%(4/58), and there was no significant difference(χ2=0.414,P=0.667).Conclusions Tamsulosin hydrochloride combined with clear stasis and kidney decoction in patients with chronic prostatitis can significantly relieve the clinical symptoms and improve the immune function of the local prostate, and the effect is exact.
