Deciphering the core microbes and their interactions in spontaneous Baijiu fermentation: A comprehensive review.

The spontaneous Baijiu fermentation system harbors a complex microbiome that is highly dynamic in time and space and varies depending on the Jiuqu starters and environmental factors. The intricate microbiota presents in the fermentation environment is responsible for carrying out various reactions. These reactions necessitate the interaction among the core microbes to influence the community function, ultimately shaping the distinct Baijiu styles through the process of spontaneous fermentation. Numerous studies have been conducted to enhance our understanding of the diversity, succession, and function of microbial communities with the aim of improving fermentation manipulation. However, a comprehensive and critical assessment of the core microbes and their interaction remains one of the significant challenges in the Baijiu fermentation industry. This paper focuses on the fermentation properties of core microbes. We discuss the state of the art of microbial traceability, highlighting the crucial role of environmental and starter microbiota in the Baijiu brewing microbiome. Also, we discuss the various interactions between microbes in the Baijiu production system and propose a potential conceptual framework that involves constructing predictive network models to simplify and quantify microbial interactions using co-culture models. This approach offers effective strategies for understanding the core microbes and their interactions, thus beneficial for the management of microbiota and the regulation of interactions in Baijiu fermentation processes.

Association of Cytokines with Clinical Indicators in Patients with Drug-Induced Liver Injury.

Objective: To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury (DILI) caused by different drugs and their correlation with clinical indicators. Method: The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests (RUCAM) scoring criteria and clinically diagnosed with DILI. Based on Chinese herbal medicine, cardiovascular drugs, non-steroidal anti-inflammatory drugs (NSAIDs), anti-infective drugs, and other drugs, patients were divided into five groups. Cytokines were measured by Luminex technology. Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results: 73 patients were enrolled. Age among five groups was statistically different ( P = 0.032). Alanine aminotransferase (ALT) ( P = 0.033) and aspartate aminotransferase (AST) ( P = 0.007) in NSAIDs group were higher than those in chinese herbal medicine group. Interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) in patients with Chinese herbal medicine (IL-6: P < 0.001; TNF-α: P < 0.001) and cardiovascular medicine (IL-6: P = 0.020; TNF-α: P = 0.001) were lower than those in NSAIDs group. There was a positive correlation between ALT ( r = 0.697, P = 0.025), AST ( r = 0.721, P = 0.019), and IL-6 in NSAIDs group. Conclusion: Older age may be more prone to DILI. Patients with NSAIDs have more severe liver damage in early stages of DILI, TNF-α and IL-6 may partake the inflammatory process of DILI.

An Innovative Preauricular Free Flap Pedicled with Retrograde Vascular (PFFPRV) for Pediatric Nasal Reconstruction.

SUMMARY: Nasal reconstruction in pediatric patient is very challenging and it requires consideration of later nasal development. Herein, we introduce an innovative preauricular free flap pedicled with retrograde vascular (PFFPRV) for pediatric nasal reconstruction. In this PFFPRV technique, the retrograde superficial temporal vessels were used as the flap pedicle. The lateral alar artery and angular vein were used as vessels of the nasal recipient zone. The flap vessels were anastomosed directly to the recipient area vessels without additional vessel transplantation. Eight pediatric patients with nasal defects underwent this operation. All patients were followed up for more than 2 years. Patients' medical history data were retrospectively analyzed. Preoperative and postoperative facial photos were compared and analyzed. The satisfaction of patient's parents with the aesthetic results was assessed. All patients were successfully operated without intraoperative complications. None of the procedures required additional blood vessel grafts. One patient developed a vascular crisis the next day after the surgery and underwent vascular exploration operation. The free flaps of all patients survived without wound infection or necrosis. The color difference of flap gradually became unobvious. The transplanted flap did not show obvious contracture or retraction, and the nose was symmetrical and developed well. The parents of all patients were satisfied with the surgical results. We think this PFFPRV technique can be a reasonable alternative strategy for reconstruction of pediatric nasal defect, with no adverse effect on nasal development and no need of vascular transplantation. LEVEL OF EVIDENCE: Level IV, therapeutic study.

The effect of refined psychological pain nursing combined with IMB nursing on the pain, sleep and quality of life of patients after cervical cancer surgery.

To explore the effect of refined psychological pain nursing combined with information-motivation-behavioral (IMB) care model on the pain, sleep and quality of life of patients after cervical cancer surgery, so as to provide reference and basis for the nursing of patients after cervical cancer surgery. The clinical data of 798 postoperative cervical cancer patients who were nursing in our hospital from January 2018 to December 2022 were included in this retrospective study and divided into the control group (n = 382) and observation group (n = 416) according to the different care methods. The control group used refined psychological pain nursing, and on this basis, the observation group used IMB nursing to observe and compare the differences in pain, sleep and quality of life between the 2 groups. There was no significant difference in pain between the 2 groups before nursing (P > .05). After nursing, the pain of both groups was significantly improved. The scores of NRS, VAS, and PSEQ of the observation group were significantly better than those of the control group (P < .001). After nursing, the quality of life scores such as emotion, cognition, society, and overall health were significantly higher in the observation group than those of the control group, while physical, fatigue, nausea, vomiting, and pain were significantly lower than those of the control group (P < .05). The negative emotion score of the observation group was significantly lower than that of the control group (P < .001). The residual urine volume and urinary tract infection rate of the observation group were significantly lower than those of the control group (P < .05). The bladder function was significantly better than that of the control group (P < .05). The analgesic effect of refined psychological pain nursing combined with IMB nursing on patients after cervical cancer surgery is better than that of refined psychological pain nursing alone, which can promote pain recovery and further improve the quality of life and sleep quality of patients.

An Innovative Stent Consisting of Expanded Polytetrafluoroethylene and Ear Cartilage in Rhinoplasty For Asians: Application I of Dai's Exogenous Extension Stent Concept.

BACKGROUND: Restricted ventilation is common after rhinoplasty with an endogenous extension stent. The authors proposed an exogenous extension stent concept for Asian rhinoplasty patients to avoid this problem. Herein, we introduce an innovative stent in rhinoplasty for Asians, which is an application of this concept. METHODS: An L-shaped expanded polytetrafluoroethylene is hand-carved, and the long arm is placed at the nose back to improve the flatness of the nose, while the short arm supports the nasal column to raise the nose tip. The prosthesis does not occupy nasal volume and therefore theoretically does not affect nasal ventilation. The fan-shaped ear cartilage was placed at the nasal tip to prevent visualization of the nasal tip. The safety and effectiveness of this method were verified through 20 years of clinical practice. The difficulty of learning and popularizing the method was tested through the course of rhinoplasty among 22 plastic surgeons. RESULTS: After 20 years of clinical practice, it was found that this stent could not only effectively improve the nasal dorsum and tip morphology, but also did not actually affect the nasal volume and thus did not affect the nasal ventilation of patients. Among the trainees in plastic surgery, we found that it was not difficult to learn this method of rhinoplasty and the trainees could complete the prosthesis carving well after standardized training. CONCLUSION: This stent consisting of expanded polytetrafluoroethylene and ear cartilage is suitable in rhinoplasty for Asians with significant advantages, one of which is that it has no risk of resulting in restricted nasal ventilation. LEVEL OF EVIDENCE: Level IV.

External Z-plasty Technique for Correction of Alar Retraction in Asian Patients.

BACKGROUND: Current strategies for correcting alar retraction mainly include cartilage grafting and composite grafting, which are relatively complicated and may produce injury to the donor site. Herein, we introduce a simple and effective external Z-plasty technique for correcting alar retraction in Asian patients with poor skin malleability. METHODS: Twenty-three patients were presented with alar retraction and poor skin malleability, and they were very concerned about the shape of the nose. These patients undergoing external Z-plasty surgery were analyzed retrospectively. In this surgery, no grafts were needed, and the location of the Z-plasty was according to the highest point of the retracted alar rim. We reviewed the clinical medical notes and photographs. During the postoperative follow-up period, patients' reported satisfaction with aesthetic outcome were also evaluated. RESULTS: The alar retraction of all the patients was successfully corrected. The postoperative mean follow-up period was 8 months (range: 5-28 mo). No incidents of flap loss, recurrence of alar retraction, or nasal obstruction were observed during postoperative follow-up. Within postoperative 3-8 weeks, minor red scarring was visible at the operative incisions in most patients. However, these scars turned unobvious after postoperative 6 months. There were 15 cases (15/23) being very satisfied with the aesthetic outcome of this procedure. Seven patients (7/23) were satisfied with the effect and the invisible scar of this operation. Only one patient was dissatisfied with the scar, but she was satisfied with the correction effect of the retraction. CONCLUSION: This external Z-plasty technique can be an alternative method for correction of alar retraction with no need of cartilage grafting, and the scar can be unobvious with fine surgical suture. However, the indications should be limited in patients with severe alar retraction and poor skin malleability, who should not particularly care about the scars.

The impact of hospital-family integrated continuation nursing based on information technology on patients unhealthy mood, family function and sexual function after cervical cancer surgery.

The objective of this study was to explore the impact on hospital-family integrated continuation care based on information technology on the negative emotions, family function, and sexual function of patients after cervical cancer surgery. The clinical case data onto 114 postoperative cervical cancer patients who were nursing in our hospital from July 2019 to July 2021 were selected and were divided into a control group and an observation group. The control group used routine nursing care, and on this basis, the observation group used information technology as the basis for hospital-family integrated continuation care, and we observed and compared the differences in the 2 groups of patients bad mood, family function, and sexual function. The score of anxiety (P = .017), depression (P = .009), fatigue rating (P = .012), and anger (P < .001) in the observation group after care were significantly lower than those in the control group. Problem solving, role, emotional response, emotional involvement, and family function total score in the observation group after care was significantly lower than those in the control group (P < .05). Sexual desire score, sexual arousal score, vaginal lubrication score, orgasm score, sexual satisfaction score, dyspareunia score, and Female Sexual Function Inventory total scores in the observation and control groups after care were significantly higher than those before care (P < .05). The sexual function scores in the observation group after care was significantly higher than those in the control group (P < .05). The hospital-family integrated continuation care based on information technology is more effective than conventional nursing care for patients after cervical cancer surgery.

Continuous dynamic identification of key genes and molecular signaling pathways of periosteum in guided bone self-generation in swine model.

BACKGROUND: Guided bone self-generation with periosteum-preserved has successfully regenerated mandibular, temporomandibular and interphalangeal joint. The aim of this study was to investigate the dynamic changes of gene expression of periosteum which was involved in the guided bone self-generation. METHODS: Rib defects of critical size were created in mature swine with periosteum-preserved. The periosteum was sutured into a sealed sheath that closed the bone defect. The periosteum of trauma and control sites were harvested at postoperative 9 time points, and total RNA was extracted. Microarray analysis was conducted to identify the differences in the transcriptome of different time points between two groups. RESULTS: The differentially expressed genes (DEGs) between control and trauma group were different at postoperative different time points. The dynamic changes of the number of DEGs fluctuated a lot. There were 3 volatility peaks, and we chose 3 time points of DEG number peak (1 week, 5 weeks and 6 months) to study the functions of DEGs. Oxidoreductase activity, oxidation-reduction process and mitochondrion are the most enriched terms of Go analysis. The major signaling pathways of DEGs enrichment include oxidative phosphorylation, PI3K-Akt signaling pathway, osteoclast differentiation pathway and Wnt signaling. CONCLUSIONS: The oxidoreductase reaction was activated during this bone regeneration process. The oxidative phosphorylation, PI3K-Akt signaling pathway, osteoclast differentiation pathway and Wnt signaling may play important roles in the guided bone self-generation with periosteum-preserved. This study can provide a reference for how to improve the application of this concept of bone regeneration.

Recent developments in the immunopathology of COVID-19.

There has been an important change in the clinical characteristics and immune profile of Coronavirus disease 2019 (COVID-19) patients during the pandemic thanks to the extensive vaccination programs. Here, we highlight recent studies on COVID-19, from the clinical and immunological characteristics to the protective and risk factors for severity and mortality of COVID-19. The efficacy of the COVID-19 vaccines and potential allergic reactions after administration are also discussed. The occurrence of new variants of concerns such as Omicron BA.2, BA.4, and BA.5 and the global administration of COVID-19 vaccines have changed the clinical scenario of COVID-19. Multisystem inflammatory syndrome in children (MIS-C) may cause severe and heterogeneous disease but with a lower mortality rate. Perturbations in immunity of T cells, B cells, and mast cells, as well as autoantibodies and metabolic reprogramming may contribute to the long-term symptoms of COVID-19. There is conflicting evidence about whether atopic diseases, such as allergic asthma and rhinitis, are associated with a lower susceptibility and better outcomes of COVID-19. At the beginning of pandemic, the European Academy of Allergy and Clinical Immunology (EAACI) developed guidelines that provided timely information for the management of allergic diseases and preventive measures to reduce transmission in the allergic clinics. The global distribution of COVID-19 vaccines and emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with reduced pathogenic potential dramatically decreased the morbidity, severity, and mortality of COVID-19. Nevertheless, breakthrough infection remains a challenge for disease control. Hypersensitivity reactions (HSR) to COVID-19 vaccines are low compared to other vaccines, and these were addressed in EAACI statements that provided indications for the management of allergic reactions, including anaphylaxis to COVID-19 vaccines. We have gained a depth knowledge and experience in the over 2 years since the start of the pandemic, and yet a full eradication of SARS-CoV-2 is not on the horizon. Novel strategies are warranted to prevent severe disease in high-risk groups, the development of MIS-C and long COVID-19.

Dynamic transcriptome analysis of NFAT family in guided bone regeneration with occlusive periosteum in swine model.

OBJECTIVE: To investigate the dynamic expression of NFAT family of periosteum in guided bone regeneration process. MATERIAL AND METHODS: The swine ribs on one side were used as the trauma group and the contralateral side as the control group. After rib segment was removed, periosteum was sutured to form a closed cavity mimicking guided bone regeneration. The periosteum and regenerated bone tissue were collected at nine time points for gene sequencing and hematoxylin-eosin staining. The expression data of each member were extracted for analysis. Expression correlations among various members were analyzed. RESULTS: Staining showed the guided bone regeneration was almost completed 1 month after the operation with later stage for bone remodeling. The expression levels of each member in both groups changed greatly, especially within postoperative 1.5 months. The expression of NFATc1 and NFATC2IP in trauma group was significantly correlated with those of control group. The foldchange of each member also had large fluctuations especially within 1.5 months. In the trauma group, NFATc2 and NFATc4 were significantly upregulated, and there was a significant aggregation correlation of NFAT family expression between the various time points within one month, similar to the "pattern-block" phenomenon. CONCLUSION: This study revealed the dynamic expression of NFAT family in guided bone regeneration, and provided a reference for the specific mechanism. The first 1.5 months is a critical period and should be paid attention to. The significant high-expression of NFATc2 and NFATc4 may role importantly in this process, which needs further research to verify it.

Clinical Evaluation for Sublingual Immunotherapy With Dermatophagoides farinae in Polysensitized Allergic Asthma Patients.

Background: Many studies have demonstrated the efficacy of single-allergen sublingual immunotherapy (SLIT) in polysensitized patients with allergic rhinitis (AR), but less is reported in polysensitized patients with allergic asthma (AS). Method: Data of 133 adult patients with house dust mite (HDM)-induced AS who had been treated for 3 years were collected. These patients were divided into the control group (treated with low to moderate dose of inhaled glucocorticoids and long-acting ß2 agonists, n = 37) and the SLIT group (further treated with Dermatophagoides farinae drops, n = 96). The SLIT group contained three subgroups: the single-allergen group (only sensitized to HDM, n = 35), the 1- to 2-allergen group (HDM combined with one to two other allergens, n = 32), and the 3-or-more-allergen group (HDM combined with three or more other allergens, n = 29). The total asthma symptom score (TASS), total asthma medicine score (TAMS), and asthma control test (ACT) were assessed before treatment and at yearly visits. Forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) was assessed before treatment and at the end of SLIT. Results: TASS and ACT scores in the control group were significantly higher than that in the single-allergen group and the 1- to 2-allergen group after 1, 2, and 3 years of SLIT and significantly higher than that in the 3-or-more-allergen group after 3-year SLIT (all p < 0.05). TAMS of the control group was significantly higher than that of the other three groups after 0.5, 1, 2, and 3 years of SLIT (all p < 0.05). FEV1/FVC in the control group was significantly higher than baseline after 3 years of immunotherapy (p < 0.05). Conclusion: Patients sensitized to HDM with/without other allergens showed similar efficacy after 3 years of SLIT. However, the initial response of patients with three or more allergens was slower during immunotherapy process.

Correcting Wide Alar Base and Flare With Combined Sill and Alar Excision in Asian Patients.

BACKGROUND: Obvious scar and deformities are commonly observed with incision anterior to the alar-facial groove in alar excision surgery. The authors explored modified sill and alar excision to correct wide alar base and flare synchronously and decreased incident of unacceptable scar and deformities in Asian patients. METHODS: The authors conducted a retrospective cohort study including 52 consecutive patients undergoing this surgery. Contrary to previous studies, the incision for alar excision was located in the alar-facial groove and was closed by intracutaneous suture. Scars were assessed with visual analog scale and the Stony Brook Scar Evaluation Scale. Ratio of the interalar distance to intercanthal distance, nostril shape, and nostril symmetry was recorded. RESULTS: The mean follow-up time was 18 months. Visual analog scale results showed 50 patients (96.2%) reported unnoticeable scar and 2 noticeable but acceptable scar. Stony Brook Scar Evaluation Scale results indicated 49 patients (94.2%) with good scar outcomes and 3 (5.8%) with moderate scar outcomes. The mean ratio of interalar distance to intercanthal distance reduced significantly from preoperative 1.10 to postoperative 1.02. The frequency of horizon-shaped nostrils changed from preoperative 16 cases (30.8%) to postoperative 2 cases (3.8%). The frequency of the pear-shaped (preferred shape) nostrils improved from preoperative 15 cases (28.8%) to postoperative 26 cases (50.0%). The frequency of symmetrical nostril shape improved from preoperative 36 patients (69.2%) to 42 (80.8%). There were no patients with complications like alar deformities, and patients' dissatisfaction. CONCLUSIONS: When performing sill and alar excision in Asian patients, the authors recommended a modified approach with the incision for alar excision being placed in the alar-facial groove and closed by intracutaneous suture, which can avoid obvious scar and deformities in Asian patients.Level of evidence: Level 4.

Study on the mechanism of active components of Liupao tea on 3CLpro based on HPLC-DAD fingerprint and molecular docking technique.

Liupao tea, a drink homologous to medicine and food. It can treat dysentery, relieve heat, remove dampness, and regulate the intestines and stomach. The objective of this study is to explore the material basis and mechanism of Liupao tea intervention in COVID-19 and to provide a new prevention and treatment programme for COVID-19. We used high performance liquid chromatography to analyze the extract of Liupao tea and establish its fingerprint. The main index components of the fingerprint were determined using SARS-COV-2 3-chymotrypsin-like protease (3CLpro ), and an in vitro drug screening model based on fluorescence resonance energy transfer was used to evaluate its inhibitory activity in vitro. The fingerprint results showed that the alcohol extract of Liupao tea contained gallic acid, epigallocatechin gallate (EGCG), caffeine, epicatechin gallate, rutin, and ellagic acid. The molecular docking binding energies of the six index components of SARS-CoV-2 3Clpro were all less than -5.0 kJ/mol and showed strong binding affinity. The results of in vitro activity showed that the IC50 of EGCG was 8.84 µmol/L, which could inhibit SARS-CoV-2 3Clpro to a certain extent. This study unleashed that EGCG has a certain inhibitory effect on SARS-CoV-2 3CLpro , and Liupao tea has a certain significance as a tea drink for the prevention of COVID-19. PRACTICAL APPLICATIONS: The objective of this study was to explore the material basis and mechanism of Liupao tea intervention in COVID-19 and to provide a new prevention and treatment programme for COVID-19. The molecular docking binding energies of the six index components of Liupao tea with SARS-CoV-2 3CLpro were all less than -5.0 kJ/mol, among them, the enzyme activity experiment shows that EGCG has a certain inhibitory effect on SARS-CoV-2 3CLpro , it can be used as a potential SARS-CoV-2 3CLpro inhibitor. We predicted that the understandings gained in the current research may evidence that Liupao tea has a certain significance as a tea drink for the prevention of COVID-19.

Impact of Gender Difference on Anxiety in COVID-19 Patients in Quarantine Wards.

OBJECTIVE: This study aimed to investigate the gender difference in anxiety in novel coronavirus pneumonia (COVID-19) patients in the quarantine ward during the outbreak. METHODS: The self-rating anxiety scale (SAS) was used on the seventh day of isolation to analyze the anxiety levels of a total of 242 suspected or confirmed COVID-19 patients in the quarantine wards of two hospitals; 232 of these patients (112 males and 120 females) completed the anxiety scoring. The anxiety scores were compared between male and female patients using the t-test, and a scatter diagram was used for analysis. RESULTS: The SAS scores of females in quarantine wards were higher than those of males at seven days of isolation. CONCLUSION: Women with COVID-19 are more prone to anxiety than men while in isolation. It is necessary to give more attention to female patients in quarantine wards in the future, and psychological counseling may be necessary.

Multidrug Resistance of Gastric Cancer: The Mechanisms and Chinese Medicine Reversal Agents.

Chemotherapy is the main clinical treatment method of gastric cancer. Multidrug resistance (MDR) has become a common phenomenon with the development of tumors, which alleviates the effect of chemotherapy and makes it difficult to break the bottleneck of survival rate of advanced gastric cancer. Therefore, the exploration of MDR reversal agents for gastric cancer is the focus and also the difficulty of current treatment. Currently, the researches on the mechanisms of drug resistance in gastric cancer have been continuously deepened, which reveal different pathways and targets of MDR, laying a solid foundation for studying reversal agents. As a kind of natural medicine, traditional Chinese medicine (TCM) owns the characteristics of low toxicity, high safety and effectiveness. It can inhibit the occurrence, growth and metastasis of tumors, and reverse MDR via multiple pathways and mechanisms, the pathological function of which has become a research hotspot in recent years. TCM reversers are mainly divided into Chinese medicine monomers, Chinese patent medicines, and Chinese herbal compounds. With certain quantity and advantage, TCM reversers for MDR play an important role in the clinical treatment and show great potential in gastric cancer.

Reduction of cyclophosphamide-induced DNA damage and apoptosis effects of ginsenoside Rb(1) on mouse bone marrow cells and peripheral blood leukocytes.

The present study investigated the protective effects of ginsenoside Rb(1) (GRb(1)) against genotoxicity induced by cyclophosphamide (CP). Single cell gel electrophoresis, flow cytometry assay with annexin V-FITC/propidine iodide (PI) and acridine orange (AO)/ethidium bromide (EB) staining assay were employed to measure DNA damage and cell apoptosis, respectively. The activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) and the malondialdehyde (MDA) content were also investigated by a number of colormetric methods. The results showed that the CP produced significant DNA damage and cell apoptosis in mouse bone marrow cells or peripheral blood leukocytes, markedly inhibited the activities of T-SOD and GPx, and markedly increased the MDA content. GRb(1) significantly inhibited DNA damages and cell apoptosis in mouse bone marrow cells or peripheral blood leukocytes induced by CP and antagonized the reduction of CP-induced T-SOD and GPx activities, and inhibited the increase in MDA content induced by CP. The anti-tumor study of GRb(1) showed that GRb(1) did not affect the anti-tumor activities of CP. In conclusion, GRb(1) had significant protective effects against DNA damage and apoptosis induced by CP.
