OBJECTIVE: To screen the optimal regimen of acupuncture and moxibustion for obstructive sleep apnea hypopnea syndrome (OSAHS), so as to provide the evidences for clinical decision-making. METHODS: From 7 databases in Chinese and English i.e. the Full-Text Database of China Journal Network (CNKI), Wanfang Data Knowledge Service Platform (Wanfang), VIP Information Chinese Journal Service Platform (VIP), Chinese Biomedical Literature Database (SinoMed), PubMed, Web of Science (WOS) and Cochrane Library, randomized controlled trial (RCT) articals of OSAHS treated with acupuncture and moxibustion were searched. The quality of evidence was evaluated with the modified Jadad scale, the evaluation index was established and the optimal regimen of acupuncture and moxibustion for OSAHS was screened by multi-index decision analysis. RESULTS: A total of 10 RCTs were included, and the filiform needling therapy was optimal in treatment of OSAHS. The acupoints included Lianquan (CV23), Danzhong (CV17), Zhongwan (CV12), and bilateral Kongzui (LU6), Pishu (BL20), Fenglong (ST40), Zusanli (ST36), Yinlingquan (SP9) and Zhaohai (KI6). Zusanli (ST36) received the reinforcing method, Pishu (BL20) and Fenglong (ST40) were stimulated with the reducing technique, and the rest acupoints with the uniform reinforcing-reducing. Each acupoint was manually manipulated once every 10 min during the needle retention for 30 min. Acupuncture was delivered once a day, 5 times a week and for consecutive 4 weeks. Among the included literature, the severity of disease was not reported in detail, the filiform needling was the dominant intervention, the local acupoints such as Lianquan (CV23) and Panglianquan (Extra) were mainly selected. The apnea-hypopnea index and the minimum oxygen saturation were taken as the evaluation indexes, and the effect was evaluated in reference to the generally accepted standards. The attention to safety evaluation was insufficient, the report on methodology was not adequate and the quality was low. CONCLUSION Filiform needling is the dominant therapy of acupuncture and moxibustion for OSAHS, and the local acupoints are considered specially. But the quality of clinical research should be improved.

Human alphaherpesvirus 2 (HSV-2) is the main pathogen resulting human genital herpes, which poses a major threat to the socio-economic development, while there is no effective vaccine. In this study, we developed a novel lipopolyplex (LPP)-delivered mRNA vaccine expressing the HSV-2 envelope glycoprotein gD and evaluated its immunogenicity in mice. The mRNA vaccine was prepared from the genetically modified gD mRNA synthesized in vitro combined with the LPP delivery platform and it was named gD-ORI mRNA. The expression of gD antigen in the mRNA vaccine was validated in vitro by Western blotting and indirect immunofluorescence assay, then the immune responses induced by this mRNA vaccine in mice were evaluated. The immunization with gD mRNA alone induced strong humoral and cellular immune responses in mice. Robust and long-lasting gD-specific IgG antibodies were detected in the mouse serum after booster immunization with gD-ORI mRNA. The immunized mice exhibited a Th1/Th2 balanced IgG response and robust neutralizing antibodies against HSV-2, and a clear dose-response relationship was observed. The gD-specific IgG antibodies were maintained in mice for a long time, up to 18 weeks post-booster immunization. At the same time, multifunctional gD-specific CD4⁺ and CD8⁺ T cells in vaccinated mice were detected by intracellular cytokine staining (ICS). This novel gD-expressing mRNA vaccine delivered by LPP induces strong and long-lasting immune responses in mice post booster immunization and has a promising prospect for development and application. This study provides scientific evidence and reference for the development of a new mRNA vaccine for HSV-2.

Objective To investigate the effects of liraglutide on the gut microbiota of db/db diabetic mice and the predictive value of the microbial structure for the hypoglycemic efficacy.Methods The db/db mice were randomly divided into control group and liraglutide group(0.4 μg/g).Fasting blood glucose levels were measured in the mice,and fecal samples were collected to determine the structure of the gut microbiota.Results Compared with the control group,the liraglutide group exhibi-ted a significant increase in the average number of operational taxonomic unit(OTU)(P＜0.01).The number of observed species,Chao1 index and ACE index were all significantly higher in the liraglutide group than those in the control group(P＜0.05).Additionally,the liraglutide group showed a signifi-cant increase in the relative abundance of Firmicutes and a significant decrease in the abundance of Actinobacteria compared with the control group(P＜0.01).The percentage decrease in blood glucose levels in db/db mice was positively correlated with the abundance of Pseudomonadaceae and negatively correlated with the abundances of Clostridiaceae and Peptostreptococcaceae.Conclusion Liraglutide treatment can modulate the structure of the gut microbiota,increasing the number of OTU and diversity,particularly enhancing the abundance of beneficial bacteria such as Clostridium,Lachnospira and Oscillospira.The gut microbiota structure in mice serves as a predictive factor for the hypoglycemic efficacy of liraglutide,with diabetic mice exhibiting a higher abundance of Pseudomonas being more likely to benefit from liraglutide-induced hypoglycemic therapy.

Objective:To construct a novel respiratory syncytial virus (RSV) vaccine based on a recombinant influenza virus vector and evaluate its immune protective effects in mice.Methods:A recombinant H1N1 influenza A virus (IAV) expressing the extracellular domain (Gecto) of RSV A2 G protein was constructed and rescued, named as PR8NAGecto/WSN. After in vitro verification of the Gecto expression and PR8NAGecto/WSN growth kinetics, a single dose of PR8NAGecto/WSN was used to immunize BALB/c mice through intranasal administration to evaluate the efficacy of PR8NAGecto/WSN by assessing humoral (IgG, neutralizing antibody), mucosal (IgA) and cellular immunity (IFN-γ ELISPOT). Four weeks after immunization, the mice were challenged with RSV A2 or RSV B9320 to evaluate the protective effects of PR8NAGecto/WSN by analyzing mouse body weight changes, lung tissue virus titers and pathological changes. Results:A single-dose intranasal immunization with PR8NAGecto/WSN induced robust humoral, mucosal and cellular immunity in mice. Moreover, the mice in the immunized group had lower lung virus loads and mild lung pathological damages following the challenge with RSV A or RSV B subtype as compared with the control group.Conclusions:A single-dose intranasal immunization with PR8NAGecto/WSN induces robust immunity and provide protection against RSV A and B challenges in mice. This study provides new ideas and reference for the development of novel mucosal vaccines against RSV.

Gastrointestinal graft versus host disease is one of the most severe complications after hematopoietic stem cell transplantation, which can occur in patients of any age groups. Its clinical manifestations include nausea, vomit, abdominal pain, diarrhea and the like. Severe gastrointestinal graft versus host disease could directly influence the patients' clinical prognosis and therapeutic efficacy of transplantation. Here we had a review of the research progress on nutritional support and diet management strategies for gastrointestinal graft versus host disease. It is of great clinical significance to form a step-wise nutritional support model to reduce the risk of malnutrition in patients with gastrointestinal graft versus host disease, which would contribute to improving patients' general condition, relieving digestive tract symptoms, and reducing the risk of complications.

Objective:To evaluate the effect of panaxydol on ventilator-induced lung injury(VILI) in mice, and the relationship with Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor E2-related factor 2 (Nrf2) signaling pathway.Methods:Fifty healthy clean-grade male C57BL/6 mice, aged 6-8 weeks, weighing 20-25 g, were divided into 5 groups ( n=10 each) using a random number table method: control group (group C), VILI group, low-dose panaxydol group (L-PX group, 5 mg/kg), medium-dose panaxydol group (M-PX group, 10 mg/kg) and high-dose panaxydol group (H-PX group, 20 mg/kg). The corresponding doses of panaxydol were intraperitoneally injected for 7 consecutive days once a day in L-PX group, M-PX group and H-PX group. The equal volume of normal saline was given instead in C group and VILI group. Only tracheotomy was performed and animals kept spontaneous breathing for 4 h in group C, and the animals were mechanically ventilated (tidal volume 30 ml/kg, respiratory rate 70 breaths/min, inspiratory/expiratory ratio 1∶2, fraction of inspired oxygen 21%) for 4 h in VILI, L-PX, M-PX and H-PX groups. Blood samples from the femoral artery were collected for arterial blood gas analysis at 4 h of ventilation, and PaO 2 was recorded. The mice were then sacrificed under deep anesthesia, and bronchoalveolar lavage fluid (BALF), lung tissues and serum samples were collected. The concentrations of TNF-α and IL-1β in BALF and serum were measured by enzyme-linked immunosorbent assay. The wet/dry lung weight (W/D) ratio was measured, the protein concentrations in BALF were measured by bicinchoninic acid assay, the pathological changes of lung tissues were examined by HE staining, lung injury was scored, and the level of ROS in lung tissues was detected by DCFH-DA fluorescence probe.The expression of Keap1 and Nrf2 in lung tissues was detected by Western blot. Results:Compared with group C, the PaO 2 was significantly decreased, the lung injury score, W/D ratio, protein concentrations in BALF and concentrations of TNF-α and IL-1β in BALF and serum were increased, the expression of Keap1 and Nrf2 was up-regulated, and the fluorescence of ROS was enhanced in the other four groups ( P<0.05). Compared with group VILI, PaO 2 was significantly increased, the lung injury score was decreased, lung W/D ratio, protein concentrations in BALF, and concentrations of TNF-α and IL-1 β in BALF and serum were decreased, and the fluorescence of ROS was weakened in L-PX, M-PX, and H-PX groups, and the expression of Keap1 was down-regulated, the fluorescence of ROS was weakened, and the expression of Nrf2 was up-regulated in M-PX and H-PX groups ( P<0.05). Compared with group L-PX, PaO 2 was significantly increased, the lung injury score, W/D ratio, protein concentrations in BALF and concentrations of TNF-α and IL-1β in BALF were decreased, the expression of Keap1 was down-regulated, and the expression of Nrf2 was up-regulated and the fluorescence of ROS was weakened in M-PX and H-PX groups ( P<0.05). Compared with group M-PX, PaO 2 was significantly increased, the lung injury score, W/D ratio, protein concentrations in BALF and concentrations of TNF-α and IL-1β in BALF were decreased, the expression of Keap1 was down-regulated, the expression of Nrf2 was up-regulated, and the fluorescence of ROS was weakened in H-PX group( P<0.05). Conclusions:Panaxydol can reduce VILI in mice, and the mechanism may be related to activation of the Keap1/Nrf2 signaling pathway and inhibition of oxidative stress.

Objective:To evaluate the effects of GSK484 on ventilator-induced lung injury (VILI) and neutrophil extracelluar traps (NETs) in mice.Methods:Forty-eight SPF healthy male C57BL/6 mice, aged 5-6 weeks, weighing 15-20 g, were divided into 4 groups ( n=12 each) by a random number table method: spontaneous breathing group (group S), spontaneous breathing+ GSK484 intervention group (group SG), VILI group (group V), and VILI + GSK484 intervention group (group VG). The animals kept spontaneous breathing for 4 h after tracheal intubation in S and SG groups. The animals were mechanically ventilated for 4 h (tidal volume 30 ml/kg, respiratory rate 75 breaths/min, inspiratory/expiratory ratio 1∶2, positive end-expiratory pressure 0 mmHg, fraction of inspired oxygen 21%) in V and VG groups. At 3 days before developing the VILI model, GSK484 4 mg/kg was intraperitoneally injected once a day in SG and VG groups, while the equal volume of normal saline was given instead in S and V groups. Blood samples were collected from the abdominal aorta for blood gas analysis at 4 h of spontaneous breathing or mechanical ventilation, and PaO 2 was recorded. The mice were then sacrificed and bronchoalveolar lavage fluid (BALF) was collected and lung tissues were obtained for microscopic examination of the pathological changes (with a light microscope after HE staining) which were scored and for determination of wet to dry weight ratio (W/D ratio), concentrations of interleukin-1beta (IL-1β), IL-6, tumor necrosis factor-alpha (TNF-α) and myeloperoxidase (MPO) in BALF (by enzyme-linked immunosorbent assay), expression of peptidylarginine deiminase 4 (PAD4), neutrophil elastase (NE), high mobility group box 1 (HMGB1) and citrullinated-histone 3 (Cit-H3) in lung tissues (by Western blot). Results:Compared with S and SG groups, the lung injury score and W/D ratio were significantly increased, PaO 2 was decreased, concentrations of IL-1β, IL-6, TNF-α and MPO in BALF were increased, and the expression of PAD4, NE, HMGB1 and Cit-H3 in lung tissues was up-regulated in V and VG groups ( P<0.05). Compared with group V, the lung injury score and W/D ratio were significantly decreased, PaO 2 was increased, the concentrations of IL-1β, IL-6, TNF-α and MPO in BALF were decreased, and the expression of PAD4, NE, HMGB1 and Cit-H3 was down-regulated in group VG ( P<0.05). Conclusions:GSK484 can alleviate VILI in mice, and the mechanism is associated with inhibition of PAD4, reduction of the production of NETs and attenuation of inflammatory responses in lung tissues.
