Transcriptomics technology has shown remarkable application effects in multiple disease fields, but its application in severe burns, especially in the field of burn sepsis, is still superficial. The use of transcriptomics and big data methods to solve the long-standing challenges of severe burns, especially in the field of burn sepsis, has great prospects and significance. This article comprehensively discusses the application value, current status, and future prospects of transcriptomics in the study of severe burns, especially burn sepsis, in order to provide new ideas for the treatment of severe burns.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To observe the efficacy and safety of the M receptor antagonist Bencycloquidium bromide nasal spray in treatment of seasonal allergic rhinitis with runny nose as the main symptom.

Objective:To evaluate the early efficacy and safety of transnasal endoscopic decompression in the annulus of zinn (AZ) region for refractory dysthyroid optic neuropathy (DON) and to preliminarily analyze the correlated factors of postoperative visual function outcome.Methods:From July 2021 to January 2023, 35 patients (56 eyes) with DON who received AZ area decompression in Peking University Third Hospital were included retrospectively, including 9 males (13 eyes) and 26 females (43 eyes), aging (52.2±12.0) years. Among them, 35 eyes underwent two-wall (medial and inferior) orbital decompression using an endonasal endoscopic approach, while 21 eyes received three-wall (medial, lateral, and inferior) orbital decompression through a combined approach. Key parameters such as best corrected visual acuity (BCVA), visual field (MD value), eyeball prominence, intraocular pressure, and complications were recorded. Postoperative data were collected one month after surgery. The statistical analysis was performed using paired t-test and Spearman correlation analysis. Results:Significant outcomes were observed post surgery in BCVA, visual field, intraocular pressure and proptosis ( t value was 8.37, 6.17, 4.50, and 9.20, respectively, all P<0.001). The reduction in proptosis was statistically significant between the 2-wall and 3-wall orbital decompression groups ( t=-2.82, P=0.007). Changes in BCVA, visual field, and intraocular pressure before and after surgery was greater in the 3-wall orbital decompression group compared to 2-wall orbital decompression group, although the difference was not statistically significant (all P>0.05). Change in postoperative visual acuity and visual field was significantly positively correlated with preoperative visual acuity and preoperative visual field (all P<0.001). Similarly, change in intraocular pressure and proptosis was positively correlated with preoperative intraocular pressure and preoperative protrusion (all P<0.001). Preoperative diplopia was reported in seven patients (20.0%), and two new cases (5.7%) were noted post-operation, which resolved within 3 months after surgery. Conclusions:Endoscopic endonasal decompression of the AZ area is a safe and effective surgical treatment for DON, with notable improvements in BCVA. Furthermore, three-orbital wall decompression seems to yield better outcomes in terms of eye retraction.

This study aimed to uncover underlying mechanisms and promising intervention targets of heart failure (HF)-related stroke. HF-related dataset GSE42955 and stroke-related dataset GSE58294 were obtained from the Gene Expression Omnibus (GEO) database. Weighted gene co-expression network analysis (WGCNA) was conducted to identify key modules and hub genes. Gene Ontology (GO) and pathway enrichment analyses were performed on genes in the key modules. Genes in HF-and stroke-related key modules were intersected to obtain common genes for HF-related stroke, which were further intersected with hub genes of stroke-related key modules to obtain key genes in HF-related stroke. Key genes were functionally annotated through GO in the Reactome and Cytoscape databases. Finally, key genes were validated in these two datasets and other datasets. HF-and stroke-related datasets each identified two key modules. Functional enrichment analysis indicated that protein ubiquitination, Wnt signaling, and exosomes were involved in both HF-and stroke-related key modules. Additionally, ten hub genes were identified in stroke-related key modules and 155 genes were identified as common genes in HF-related stroke. OTU deubiquitinase with linear linkage specificity (OTULIN) and nuclear factor interleukin 3-regulated (NFIL3) were determined to be the key genes in HF-related stroke. Through functional annotation, OTULIN was involved in protein ubiquitination and Wnt signaling, and NFIL3 was involved in DNA binding and transcription. Importantly, OTULIN and NFIL3 were also validated to be differentially expressed in all HF and stroke groups. Protein ubiquitination, Wnt signaling, and exosomes were involved in HF-related stroke. OTULIN and NFIL3 may play a key role in HF-related stroke through regulating these processes, and thus serve as promising intervention targets.

Objective: To investigate the effects of basic fibroblast growth factor (bFGF) on healing of Mycobacterium tuberculosis infective wound in New Zealand rabbit after debridement. Methods: Thirty-two New Zealand rabbits (3 to 4 months old, no matter male or female) were intradermally injected with 0.1 mL of complete Freund′s adjuvant on the buttocks. Six weeks later, each rabbit was injected with 0.5 mL 5×10⁷ colony forming unit/mL Bacillus Calmette-Guerin on both sides of the back to reproduce the model of Mycobacterium tuberculosis infective wound in New Zealand rabbit. After successful modeling, the 32 rabbits were divided into growth factor (GF) group, antituberculosis drug (AD) group, combined treatment (CT) group, and blank control (BC) group according to the random number table, with 8 rabbits in each group. After a complete debridement, the wounds of rabbits in group GF were treated with recombinant bovine bFGF gel (300 IU/cm^2, about 0.45 g for each wound), the wounds of rabbits in group AD were covered with gauze which was impregnated with 6 mL isoniazid injection and 0.15 g rifampicin powder-injection, the wounds of rabbits in group CT were covered with gauze which was impregnated with isoniazid injection and rifampicin powder-injection after being treated with recombinant bovine bFGF gel as before, the wounds of rabbits in group BC were covered with sterile gauze, with dressing change of once every two days until the wounds were completely healed. Immediately after surgery and on post surgery day (PSD) 7, 14, 21, and 28, the wounds of rabbits in each group were observed with naked eyes and photos. On PSD 7, 14, 21, and 28, the wound healing rate was calculated and the complete healing time of wound was recorded. On PSD 7, 14, 21, and 28, the tissue samples of wound edge were collected for histomorphological observation with hematoxylin and eosin staining and Masson staining. On PSD 21, the number of microvessels was counted with immunohistochemical method. On PSD 7, 14, 21, and 28, the content of hydroxyproline in wound edge was determined by enzyme-linked immunosorbent assay. The numbers of samples of above-mentioned experiments were all 8. Data were processed with analysis of variance for repeated measurement, analysis of variance of factorial design, one-way analysis of variance, least significant difference test and Bonferroni correction. Results: (1) The rabbits in four groups all survived to the end of experiment. Immediately after surgery, edema was observed in basal wounds of rabbits in the four groups. On PSD 7, the wounds of rabbits in the 4 groups were contracted with scabs and less edema. The wounds of rabbits in groups GF and CT became redder. On PSD 14, the wounds of rabbits in the 4 groups contracted obviously. There were no obvious exudates in wounds of rabbits in groups AD and CT, while 1 wound of rabbit in group GF and 2 wounds of rabbits in group BC became red and swelling with purulent exudates. On PSD 21, wounds of rabbits in groups GF and CT were basically healed, while 2 wounds of rabbits in group BC healed slowly with purulent secretion. On PSD 28, wounds of rabbits in the 4 groups were basically healed, while 2 wounds of rabbits in group BC hardly healed with redness and swelling. (2) From PSD 7 to 28, the wound healing rates of rabbits in groups GF, AD, and CT were significantly higher than those in group BC (P<0.05). On PSD 14 and 21, the wound healing rates of rabbits in groups GF and CT were significantly higher than those in group AD (P<0.05). From PSD 7 to 28, the wound healing rates of rabbits in group GF were close to those in group CT (P>0.05). (3) The complete healing time of wounds of rabbits in groups GF, AD, and CT was significantly shorter than that in group BC (P<0.05). The complete healing time of wounds of rabbits in groups GF and CT was significantly shorter than that in group AD (P<0.05). The complete healing time of wounds of rabbits in group GF was close to that in group CT (P>0.05). (4) On PSD 7, a large number of inflammatory cells infiltration were observed in wound tissue of rabbits in the 4 groups and a few epithelial cells were observed in wound tissue of rabbits in groups GF, AD, and CT. On PSD 14, more epithelial cells were observed in wound tissue of rabbits in groups GF and CT, and an obvious reduction of inflammatory cells infiltration was observed in wound tissue of rabbits in groups AD and CT. On PSD 21, there was a complete wound tissue structure and distinctive nuance of dyeing in wound tissue of rabbits in groups GF and CT while thinner new epithelium in wound tissue of rabbits in groups AD and BC, and inflammatory cell infiltration was observed in wound tissue of rabbits in group BC. On PSD 28, there was a complete wound tissue structure in wound tissue of rabbits in the 4 groups, the new epithelium in wound tissue of rabbits in groups GF, AD, and CT was thicker than that in group BC. (5) On PSD 7 and 14, the quantity of collagen fibers in wound tissue of rabbits in groups GF and CT was larger than that in the other two groups. On PSD 21, a large quantity of fibroblasts and well reorganized collagen fibers were observed in wound tissue of rabbits in groups GF and CT, a moderate quantity of fibroblasts and collagen fibers in a random arrangement were observed in wound tissue of rabbits in group AD, and a little quantity of fibroblasts and collagen fibers were observed in wound tissue of rabbits in group BC. On PSD 28, the quantity of collagen fibers in wound tissue of rabbits in the 4 groups was close to that of normal skin tissue, and the collagen fibers performed more well reorganized in wound tissue of rabbits in groups GF and CT. (6) On PSD 21, the numbers of microvessels per 200-time visual field in wound edge of rabbits in groups GF (31.6±1.2), AD (27.5±1.3), and CT (32.8±1.6) were significantly higher than the number in group BC (22.3±1.7, P<0.05). The numbers of microvessels in wound edge of rabbits in groups GF and CT were significantly higher than the number in group AD (P<0.05). The number of microvessels in wound edge of rabbits in group GF was close to that in group CT (P>0.05). (7) On PSD 7 and 28, there were no statistically significant differences in content of hydroxyproline in wound edge of rabbits in the 4 groups (F=0.916, 1.752, P>0.05). On PSD 14 and 21, the content of hydroxyproline in wound edge of rabbits in groups GF, AD, and CT was significantly higher than that in group BC (P<0.05). The content of hydroxyproline in the wound edge of rabbits in groups GF and CT was significantly higher than that in group AD (P<0.05). The content of hydroxyproline in the wound edge of rabbits in group GF was close to that in group CT (P>0.05). Conclusions bFGF can be used solely or combined with AD to promote Mycobacterium tuberculosis infective wound healing in New Zealand rabbit after complete debridement of wound, which is better than single use of AD.

Objective We aimed to investigate whether sex hormone levels including total testosterone, estradiol, estradiol/total testosterone, and dehydroepiandrosterone ( DHEA ) were associated with macrovascular complications among Shanghai community-dwelling diabetic men. Methods Relying on the Environmental Pollutant Exposure and Metabolic Diseases in Shanghai (METAL) study (ChiCTR1800017573, www.chictr.org.cn), 2147 male diabetic participants were recruited from 10 communities. Carotid plaques and common carotid artery ( CCA) diameters were detected by carotid ultrasound. Cardiovascular disease ( CVD) was defined as a self-reported diagnosis of CVD, including coronary heart disease, myocardial infarction, or stroke. Results ( 1) The prevalence of CVD in this study was 36. 0％, and patients with CVD had higher rates of hypertension and dyslipidemia than those without CVD. ( 2) After controlling for multiple factors, serum DHEA levels were negatively correlated with the prevalence of CVD while estradiol levels were positively correlated with both the prevalences of CVD and carotid plaque, estradiol/total testosterone ratio was also positively correlated with the prevalence of CVD. ( 3) In subgroup with unilateral/bilateral CCA plaque, and after controlling for multiple factors, total serum testosterone was negatively associated with the mean CCA diameter. Conclusion The incidence of macrovascular complications was lower in male diabetic patients with higher serum total testosterone and DHEA levels and lower estradiol levels, suggesting that sex hormone levels may be a window for the diagnosis and treatment of diabetic macrovascular complications.

Objective: To construct a Tat-dependent MazF expression vector pcDNA3.1-GFP-HA-MazF-U3TAR. Methods: HIV-1 U3TAR and MazF gene were amplified from pCR2.1-U3TAR and pET28a-MazF, respectively. Two gene fragments were linked together to form U3TAR-MazF by an overlapping PCR, and then cloned into pMD18T. An N-terminal HA tag was added to MazF to form U3TAR-MazF-HA. After double enzyme digestion using EcoR I and Hind Ⅲ, U3TAR-MazF-HA was reversely inserted into pcDNA 3.1 to form pcDNA3.1-HA-MazF-U3TAR. Then, a fluorescent reporter gene GFP was inserted into the downstream of U3TAR to form pcDNA3.1-GFP-HA-MazF-U3TAR. Results: The co-transfection experiments with pcDNA3.1-tat-flag showed that pcDNA3.1-GFP-HA-MazF-U3TAR is Tat dependent. MazF was expressed only under the presence of Tat. In addition, compared with the cells transfected with pcDNA3.1-GFP-HA-MazF-U3TAR, less green fluorescent signal was observed in the cells co-transfected with pcDNA3.1-GFP-HA-MazF-U3TAR and pcDNA3.1-tat-flag, indicating that expressed MazF down-regulated the expression of GFP. Conclusions The expression vector pcDNA3.1-GFP-HA-MazF-U3TAR will provide an important tool for the development of MazF-based AIDS gene therapy strategies.

Objective: To evaluate the postoperative clinical effects of balloon sinuplasty on chronic rhinosinusitis. Methods: PubMed, OVID, Embase, Cochrane Library, Proquest, Web of Science, Sinomed, Wan Fang and CNKI database (from established time to March of 2017) were searched for trials about the chronic rhinosinusitis treated by balloon sinuplasty. The relavent literatures were screened, and the prospective control studies were chosen. Lund-Mackay and SNOT-20 scores were used as the outcome idicators, and the methodological quality of the literatures were evaluated strictly. The extracted data were analyzed by Revman 5.3 software. Results: A total of 7 prospective before-after self-controlled studies were included, and the overall quality of which was relatively high. Meta-analysis showed that the Lund-Mackay scores at 6 months post-operation, the SNOT-20 scores at 6 months and more than 1 year post-operation were significant lower than baseline when balloon sinuplasty used in the surgery; the SNOT-20 scores at more than 1 year post-operation was lower than baseline when a standalone ballon sinuplasty was performed. All the results was statistically significant (P<0.05), and all the SMD were more than 0.8. Conclusions The postoperative effect of balloon sinuplasty on chronic rhinosinusitis is obvious, and the subjective symptoms in patients is relieved effectively.
