Monocots and eudicots have more conservative flower water use strategies than basal angiosperms.

Water balance is crucial for the growth and flowering of plants. However, the mechanisms by which flowers maintain water balance are poorly understood across different angiosperm branches. Here, we investigated 29 floral hydraulic and economic traits in 24 species from ANA grade, magnoliids, monocots, and eudicots. Our main objective was to compare differences in flower water use strategies between basal angiosperms (ANA grade and magnoliids) and derived group (monocots and eudicots). We found that basal angiosperms had richer petal stomatal density, higher pedicel hydraulic diameter, and flower mass per area, but lower pedicel vessel wall reinforcement and epidermal cell thickness compared to monocots and eudicots. We also observed significant trade-offs and coordination among different floral traits. Floral traits associated with reproduction, such as floral longevity and size, were strongly linked with physiological and anatomical traits. Our results systematically reveal the variation in flower economic and hydraulic traits from different angiosperm branches, deepening understanding of flower water use strategies among these plant taxa. We conclude that basal angiosperms maintain water balance with high water supply, whereas monocots and eudicots maintain a more conservative water balance.

Efficacy and safety of dupilumab in the treatment of kimura's disease.

BACKGROUND: Kimura's disease (KD) is a rare chronic inflammatory condition characterized by nodules and lymphadenopathy in the head and neck region, exhibiting type II inflammation. Dupilumab is commonly used against type II inflammation. AIM: To evaluate the efficacy and safety of dupilumab in KD patients. DESIGN: The real-world study was conducted in a hospital in China. METHODS: Six male patients with a mean age of 24.50 ± 15.47 years were treated with dupilumab following the same protocol as that for atopic dermatitis (AD). Clinical and laboratory indicators, such as maximum nodule diameter, blood eosinophil count, eosinophil percentage, and total serum IgE levels were assessed at baseline, week 12, and week 24. Adverse events were documented. Paired t-tests and one-way ANOVA were used for statistical analysis. RESULTS: The results showed significant reductions in the longest nodule diameter at week 12 (P = 0.008) and week 24 (P = 0.001) compared to baseline. Blood eosinophil count decreased by 57.95% (P = 0.024) at week 12 and 90.59% (P = 0.030) at week 24. Eosinophil percentage decreased by 58.44% (P = 0.026) at week 12 and 89.37% (P = 0.013) at week 24. Total serum IgE levels decreased by 78.02% (P = 0.040) at week 12 and 89.55% (P = 0.031) at week 24. The presence of AD did not affect the results. One patient experienced temporary facial erythema after 32 weeks of treatment, which resolved with topical treatment. No other adverse events were reported. CONCLUSION: Dupilumab demonstrated effectiveness in treating KD without severe adverse events.

3D Printed Ion-Responsive Personalized Transdermal Patch.

Microneedle patches are easy-to-use medical devices for transdermal administration. However, the insufficient insertion of microneedles due to the gap between planar patches and contoured skin affects drug delivery. Herein, we formulate a prepolymer for high-fidelity three-dimensional (3D) printed personalized transdermal patches. With the excellent photoinitiation ability of 2-(4-methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine (Tz), a high-fidelity and precise microneedle patch is successfully fabricated. Upon irradiation of the white illuminator, the doped gold nanoparticles (AuNPs) in the patch release heat and promisingly induce sweat production. With the introduction of Na+, the dominant component of sweat, the curvature of the produced transdermal patch is observed due to the ion-induced network rearrangement. The alkanethiol-stabilized AuNP with an end group of a carboxyl group causes controlled drug release behavior. Furthermore, the irradiation-induced photothermal heating of AuNP can facilitate the sustainability of drug release thanks to the substantially increased particle size of AuNP. These findings demonstrate that the developed prepolymer is a promising candidate for the production of transdermal patches fitting the curvature of the body surface.

[Feasibility and efficacy of pre-management of superior laryngeal artery in endoscopic surgery for hypopharyngeal cancer].

Objective: To explore the feasibility and efficacy for the dissection and ligation of the superior laryngeal artery in endoscopic surgery for hypopharyngeal cancer. Methods: Eight cadaveric heads were selected, and the laryngopharynxes were harvested. The positions of the superior laryngeal arteries entering the larynxes were dissected and observed under endoscopic vision, and their anatomical characteristics were summarized. Twenty-nine patients (all were male, aged 39-74 years old) with hypopharyngeal cancer who underwent transoral endoscopic surgery at the Department of Otorhinolaryngology Head and Neck Surgery of the Second Xiangya Hospital, Central South University from January 2018 to December 2019 were selected, and the patients were randomly divided into two groups by drawing lots, namely, the superior laryngeal artery was actively dissected and occluded during surgery in observation group (n=15) or not in control group (n=14). The differences in surgical time, bleeding volume, postoperative complications, and postoperative disease-free survival rate were compared between the two groups. Statistical analysis was conducted using SPSS 25.0 software. Results: The entry point of the superior laryngeal artery into the larynx was approximately at the level of the superior edge of the thyroid cartilage, and entered the larynx at the posterior one-third of the lateral wall of the pyriform fossa. The superior laryngeal artery might be determined through endoscopic exploration in all patients of observation group. The endoscopic surgery time [(40.00±7.56) minutes] and intraoperative bleeding volume [(24.00±8.28) ml] in the observation group were respectively less than those [(48.57±14.06) minutes and (42.86±15.41) ml] in the control group, and the differences were statistically significant (t=-2.064, P=0.049; t=-4.064, P=0.001). There was no case with postoperative bleeding in the observation group, but with one case of postoperative bleeding in the control group. Total disease free survival rate was 86.2% and there was no significant difference in disease free survival rates between the two groups during a follow-up period of at least 36 months (P=0.986). Conclusion: Dissection of the superior laryngeal artery during endoscopic surgery for hypopharyngeal cancer is feasible, and pre-management and occlusion of the superior laryngeal artery can effectively reduce intraoperative bleeding.

[Regulation of oral microbiota homeostasis and oral diseases].

Oral microbiome consists of diverse bacteria, viruses, fungi, and protozoan populations, with whose stability, functionality, and assembly process are regulated by complex interactions between the host and microbes. High-throughput sequencing technology provides insights into the classification structure, genomic composition, function, and dynamical changes of oral microbiome under healthy and morbid conditions. This review aims to outline the establishment and homeostasis maintenance of regulating oral microbiome, as well as the common oral disease-related microbial imbalance, influencing factors and emerging methods. With perspectives from microbiology, immunology, and multi-omics, we can delve into the complex molecular dialogue between the human body and microbes. Deep understandings of the assembly principles, intercellular signals, stress adaptability, and triggering factors of microbial imbalance are crucial for developing new diagnostic technologies, treatment plans, and custom probiotics. These methods can precisely target and minimize disruption to the oral microbiome. Regulating oral microbiome by using methods such as small molecules, diet, prebiotics, probiotics, phages offers new opportunities to enhance oral and overall health.

Dietary supplementation of proteases on growth performance, nutrient digestibility, blood characteristics and gut microbiota of growing pigs fed sorghum-based diets.

Low-tannin sorghum is an excellent energy source in pig diets. However, sorghum contains several anti-nutritional factors that may have negative effects on nutrient digestibility. The impacts of proteases on growth performance, nutrient digestibility, blood parameters, and gut microbiota of growing pigs fed sorghum-based diets were studied in this study. Ninety-six pigs (20.66 ± 0.65 kg BW) were allocated into three groups (eight pens/group, four pigs/pen): (1) CON (control diet, sorghum-based diet included 66.98% sorghum), (2) PRO1 (CON + 200 mg/kg proteases), (3) PRO2 (CON + 400 mg/kg proteases) for 28 d. No differences were observed in growth performance and apparent total tract digestibility (ATTD) of nutrients between CON and PRO1 groups. Pigs fed PRO2 diet had increased (P < 0.05) BW on d 21 and 28, and increased (P < 0.05) average daily gain during d 14-21 and the overall period compared with pigs fed CON diet. In addition, pigs fed PRO2 diet had improved (P < 0.05) ATTD of gross energy, CP, and DM compared with pigs fed CON and PRO1 diets. Pigs fed PRO2 diet had lower (P < 0.05) plasma globulin (GLB) level and higher (P < 0.05) plasma glucose, albumin (ALB) and immunoglobulin G levels, and ALB/GLB ratio than pigs fed CON and PRO1 diets. Furthermore, pigs fed PRO2 diet had decreased (P < 0.05) the relative abundance of Acidobacteriota at the phylum level and increased (P < 0.05) the relative abundance of Prevotella_9 at the genus level. The linear discriminant analysis effect size analysis also showed that pigs fed PRO2 diet had significantly enriched short-chain fatty acid-producing bacteria, such as Subdoligranulum and Parabacteroides. In conclusion, protease supplementation at 400 mg/kg improved the growth performance of growing pigs fed sorghum-based diets, which may be attributed to the improvement of nutrient digestibility, host metabolism, immune status and associated with the altered gut microbiota profiles.

[Establishment and efficiency test of a clinical prediction model of bronchopulmonary dysplasia associated pulmonary hypertension in very premature infants].

Objective: To develop a risk prediction model for identifying bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH) in very premature infants. Methods: This was a retrospective cohort study. The clinical data of 626 very premature infants whose gestational age <32 weeks and who suffered from BPD were collected from October 1st, 2015 to December 31st, 2021 of the Seventh Medical Center of the People's Liberation Army General Hospital as a modeling set. The clinical data of 229 very premature infants with BPD of Hunan Children's Hospital from January 1 st, 2020 to December 31st, 2021 were collected as a validation set for external verification. The very premature infants with BPD were divided into PH group and non PH group based on the echocardiogram after 36 weeks' corrected age in the modeling set and validation set, respectively. Univariate analysis was used to compare the basic clinical characteristics between groups, and collinearity exclusion was carried out between variables. The risk factors of BPD associated PH were further screened out by multivariate Logistic regression, and the risk assessment model was established based on these variables. The receiver operating characteristic (ROC) area under curve (AUC) and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the model's discrimination and calibration power, respectively. And the calibration curve was used to evaluate the accuracy of the model and draw the nomogram. The bootstrap repeated sampling method was used for internal verification. Finally, decision curve analysis (DCA) to evaluate the clinical practicability of the model was used. Results: A total of 626 very premature infants with BPD were included for modeling set, including 85 very premature infants in the PH group and 541 very premature infants in the non PH group. A total of 229 very premature infants with BPD were included for validation set, including 24 very premature infants in the PH group and 205 very premature infants in the non PH group. Univariate analysis of the modeling set found that 22 variables, such as artificial conception, fetal distress, gestational age, birth weight, small for gestational age, 1 minute Apgar score ≤7, antenatal corticosteroids, placental abruption, oligohydramnios, multiple pulmonary surfactant, neonatal respiratory distress syndrome (NRDS)>stage Ⅱ, early pulmonary hypertension, moderate-severe BPD, and hemodynamically significant patent ductus arteriosus (hsPDA) all had statistically significant influence between the PH group and the non PH group (all P<0.05). Antenatal corticosteroids, fetal distress, NRDS >stage Ⅱ, hsPDA, pneumonia and days of invasive mechanical ventilation were identified as predictive variables and finally included to establish the Logistic regression model. The AUC of this model was 0.86 (95%CI 0.82-0.90), the cut-off value was 0.17, the sensitivity was 0.77, and the specificity was 0.84. Hosmer-Lemeshow goodness-of-fit test showed that P>0.05. The AUC for external validation was 0.88, and the Hosmer-Lemeshow goodness-of-fit test suggested P>0.05. Conclusions: A high sensitivity and specificity risk prediction model of PBD associated PH in very premature infants was established. This predictive model is useful for early clinical identification of infants at high risk of BPD associated PH.

[Attitude toward sexual health education and its correlates among community-based older adults in Shanghai].

Objective: To understand the attitudes toward sexual health education and its correlates among community-based older adults in Shanghai, China. Methods: From June 2020 to December 2022, a cross-sectional survey was conducted among community residents aged ≥50 in Shanghai through multi-stage sampling. The estimated sample size was 735. The questionnaire included sociodemographic characteristics, health characteristics, and history of sexual health education. The multivariable logistic regression model was used to assess the correlates of attitudes toward sexual health education among community-based older adults. Results: A total of 824 participants (489 males and 335 females) with age of (65.1±8.1) years were included, whose main age distribution was 60-69 years (45.3%). The prevalence of supporting sexual health education among older adults was 49.4% (45.2% of men and 55.5% of women). Males (aOR=0.61, 95%CI: 0.44-0.83), aged 70 years and older (aOR=0.62, 95%CI: 0.40-0.94), urban residents (aOR= 2.54, 95%CI: 1.81-3.58), self-reported very good or excellent health status (aOR=1.64,95%CI: 1.04-2.58), having depressive symptoms (aOR=0.37,95%CI: 0.15-0.85), and having a history of sexual health education (aOR=8.64,95%CI: 4.62-17.70) were associated with their attitude toward sexual health education. Conclusions: The proportion of community-based older adults in Shanghai who support sexual health education was not high. Their attitudes toward sexual health education were associated with their self-reported health status, depressive symptoms, and history of sex education. Health professionals and institutions should focus on community-based older adults with key characteristics and tailor interventions to promote the willingness to receive sexual health education among older adults in China and to promote the popularity of sexual health education in this population.

[Utilization of sexual and reproductive health services and its correlates among community- based older adults in Chongqing].

Objective: To investigate the utilization of sexual health services among community-based older adults in Chongqing and explore its potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 years was conducted in Chongqing between June 2020 and December 2022. A questionnaire including information on demographic characteristics, general health, sexual health status, and sexual health services utilization was collected. Sexual health and reproductive services utilization was defined as having ever been tested for human immunodeficiency virus (HIV), or having had a male/gynecological reproductive health examination in the past year. Logistic regression was used to examine the correlates of the utilization of sexual health services. Results: A total of 794 community-based older adults participated in the study (482 were male, and 312 were female). The mean age was (62.8±8.2) years. The proportion of HIV testing was 18.0%, and the proportion of reproductive health examination was 10.1% among community-based older adults. The results of multivariate logistic regression analysis showed that the age group of 60-69 years (aOR=0.37, 95%CI: 0.18-0.76), female (aOR=11.34, 95%CI: 5.71-22.52), monthly income ≥5 000 yuan (aOR=3.05, 95%CI: 1.01-9.27), being sexual activity (aOR=4.99, 95%CI: 2.23-11.15) was significantly associated with had a reproductive health examination in the past year. Conclusions: The proportion of sexual health services utilization among older adults was low. Older sexual health education should be further strengthened, the close relationship between older adults should be correctly guided and dealt with, and the sexual health services suitable for the older population should be formulated.

[Condom use and its correlates among community-based older adults in Chongqing].

Objective: To understand the current status of condom use and its correlates among community-based older adults in Chongqing, China. Methods: Cross-sectional study based on a multistage sampling method was conducted in Chongqing from June 2020 to December 2022. The estimated sample size was 735. Through face-to-face interviews, the investigators collected the sociodemographic characteristics, sexual behavior characteristics, awareness of AIDS prevention knowledge, etc. A multivariable logistic regression model was used to explore the correlates of condom use during the last sexual behavior among the participants. Results: A total of 761 participants were included in this study, with 476 males and 285 females, whose average age was (63.8±8.2) years old, mainly in the age group of 60-69 years (44.5%). Among the participants, the rate of condom use during the last sexual behavior was 9.7%. The multivariable logistic regression analysis indicated that correlates of condom use during the last sexual behavior included urban household registration (aOR=2.34, 95%CI: 1.12-4.89), monthly income of 1 000-4 999 Yuan, and 5 000 Yuan and above (aOR=4.49, 95%CI: 1.31-15.41; aOR=16.33, 95%CI: 4.30-62.00), self-assessed sexual behavior risk as very risky/relatively risky (aOR=3.97, 95%CI: 1.40-11.31), awareness of AIDS prevention knowledge (aOR=0.36, 95%CI: 0.21-0.62). Conclusions: The rate of condom use among community-based older adults in Chongqing is low. Comprehensive intervention measures should be taken in combination with the characteristics and needs of community-based older adults to improve awareness of AIDS prevention knowledge and perception of AIDS risk and promote condom use among this population.

[Sexually active status and its correlates among community-based older adults in Tianjin].

Objective: To understand the sexually active status among community-based older adults aged ≥50 years in Tianjin, China, and to explore the potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 was conducted between June 2020 and December 2022. The estimated sample size was 735. The survey collected questionnaire information through face-to-face interviews with investigators, including sociodemographic, health, and sexual lifestyle characteristics. The multivariable logistic regression model was used to assess correlates of sexually active status. Results: A total of 776 study participants (510 males and 266 females) were included, whose major age distribution was 50-59 years (45.9%). The overall sexual activity prevalence of the participants was 45.6%. Older age (60-69: aOR=0.67, 95%CI: 0.45-0.99; ≥70: aOR=0.12, 95%CI: 0.07-0.21), being male (aOR=1.93, 95%CI: 1.32-2.82), living in urban area (aOR=0.18, 95%CI: 0.12-0.28), living with spouse/married (aOR=2.80, 95%CI: 1.41-5.58), living alone (aOR=0.51, 95%CI: 0.27-0.96), having difficulty climbing stairs or walking (aOR=0.55, 95%CI: 0.31-0.97), having chronic diseases (one chronic disease: aOR=0.55, 95%CI: 0.36-0.85; two or more chronic diseases: aOR=0.53, 95%CI: 0.33-0.84) were associated with sexually active status among older adults. Conclusions: Many community-based older adults remained sexually active. There was an association between physical health and sexually active status among community-based older adults. Incorporating sexual health services into healthcare services for community-based older adults could be advocated, with a concurrent emphasis on enhancing the awareness and competence of providing sexual health services among community-based healthcare workers.

[Appropriate selection of multimodal fundus imaging approaches].

With the advancement of science and technology, fundus imaging modalities are rapidly changing and constantly being introduced, playing an important role in the diagnosis and treatment of fundus diseases, as well as in follow-up and prognostic assessment. Clinicians need to update their knowledge and concepts, rationally select a variety of imaging tests for diagnostic and therapeutic purposes, and consider the use of different test protocols in different clinical scenarios. This article summarizes the advantages and limitations of commonly used fundus imaging techniques based on the international research findings and personal clinical experience, with the aim of providing guidance and reference for the rational selection of multimodal fundus imaging approaches in clinical practice.

Single-stage computer-assisted approach for tumour resection and functional restoration of Brown class III maxillary defects-titanium mesh and zygomatic implants combined with vascularized anterolateral thigh flap.

The functional restoration of Brown class III maxillary defects is a challenging endeavour in oral and maxillofacial surgery. Conventional reconstruction techniques with osseous free flaps have certain limitations, such as the need for multiple operations and greater patient morbidity. This study introduces a single-stage computer-assisted approach for tumour resection and functional restoration of these defects using titanium mesh, zygomatic implants, and a vascularized anterolateral thigh flap (ALTF). Virtual surgical planning was used to simulate tumour resection, titanium mesh placement, and zygomatic implant insertion. Surgery was performed under the guidance of mixed reality and surgical navigation. The tumour was resected by total hemimaxillectomy, and the reconstruction was performed using a pre-bent patient-specific titanium mesh for the orbital floor and two zygomatic implants placed and exposed through tunnels in an ALTF. The ALTF survived without any perioperative complications. A fixed prosthesis with built-in titanium frame was delivered 4 months postoperatively. At the 1-year follow-up, there was no tumour recurrence, the implants were osseointegrated, and aesthetics and masticatory function were satisfactory. An occlusal force of 155 N was attained on the reconstructed side, compared to 127 N on the non-surgical side.

[Effects and mechanism of glycine on rat cardiomyocytes pretreated with serum from burned rats].

Objective: To investigate the effect and mechanism of glycine on rat cardiomyocytes pretreated with serum from burned rats (hereinafter referred to as burn serum). Methods: Experimental research methods were adopted. Thirty gender equally balanced Wistar rats aged 7 to 8 weeks were collected, 10 of which were used to prepare normal rat serum (hereinafter referred to as normal serum), and the other 20 were inflicted with full-thickness burn of 30% total body surface area to prepare burn serum. Primary cardiomyocytes were isolated and cultured from the apical tissue of 180 Wistar rats aged 1 to 3 days by either gender for follow-up experiments. Cells were divided into normal serum group and burn serum group treated with corresponding serum according to the random number table (the same grouping method below). Trypanosoma blue staining was performed at post treatment hour (PTH) 1, 3, 6, 9, and 12 to detect the cell survival rate. Cells were divided into burn serum alone group treated with burn serum for 6 h followed by routine culture of 30 min and 0.4 mmol/L glycine group, 0.8 mmol/L glycine group, 1.2 mmol/L glycine group, 1.6 mmol/L glycine group, and 2.0 mmol/L glycine group treated with burn serum for 6 h followed by culture of 30 min with corresponding final molarity of glycine, i.e., at post intervention hour (PIH) 6.5, the cell survival rate was detected as before. Cells were divided into normal serum group, burn serum alone group, 0.8 mmol/L glycine group, 1.2 mmol/L glycine group, and 1.6 mmol/L glycine group, with the same intervention of 6.5 h as before, respectively. The content of adenosine monophosphate (AMP) and adenosine triphosphate (ATP) was detected by high performance liquid chromatography, and the AMP/ATP ratio was calculated. The protein expressions of phosphorylated mammalian target of rapamycin complex 1 (p-mTORC1), phosphorylated p70 ribosomal protein S6 kinase (p-p70 S6K), phosphorylated eukaryotic translation initiation factor 4E-binding protein 1 (p-4E-BP1), and phosphorylated AMP-activated protein kinase (p-AMPK) were detected by Western blotting. Cells were divided into normal serum group, burn serum alone group, 0.8 mmol/L glycine group intervened as before and 0.8 mmol/L glycine+25 ng/mL rapamycin group treated with burn serum followed by culture with two reagents. The expressions of heat shock protein 70 (HSP70), metallothionein (MT), and tubulin were detected by immunofluorescence method after 30 min of corresponding culture at PTH 1, 3, and 6, i.e., at PIH 1.5, 3.5, and 6.5, and the microtubule morphology was observed at PIH 6.5. The sample number at each time point was 10. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, least significant difference (LSD)-t test, LSD test, and Bonferroni correction. Results: At PTH 1, 3, 6, 9, and 12, the cell survival rates in burn serum group were significantly lower than those in normal serum group (with t values of 4.96, 16.83, 35.51, 34.33, and 27.88, P<0.05). In burn serum group, the cell survival rate at PTH 3, 6, 9, or 12 was significantly lower than that at PTH 1 (P<0.05), the cell survival rate at PTH 6, 9, or 12 was significantly lower than that at PTH 3 (P<0.05), and the cell survival rate at PTH 6 was similar to that at PTH 9 (P>0.05) but significantly higher than that at PTH 12 (P<0.05). Treatment of 6 h was selected as the follow-up intervention time of burn serum. At PIH 6.5, compared with that in burn serum alone group, the cell survival rate in each glycine group was significantly increased (P<0.05). The cell survival rate in 0.8 mmol/L glycine group was the highest, and 0.8, 1.2, and 1.6 mmol/L were selected as subsequent glycine intervention concentrations. At PIH 6.5, the AMP/ATP ratio of cells in burn serum alone group was significantly higher than that in normal serum group, 1.2 mmol/L glycine group, or 1.6 mmol/L glycine group (P values all <0.05), and the AMP/ATP ratio of cells in 1.6 mmol/L glycine group was significantly lower than that in 0.8 mmol/L glycine group (P<0.05). At PIH 6.5, the protein expressions of p-mTORC1, p-p70 S6K, and p-4E-BP1 of cells in normal serum group, burn serum alone group, 0.8 mmol/L glycine group, 1.2 mmol/L glycine group, and 1.6 mmol/L glycine group were 1.001±0.037, 0.368±0.020, 1.153±0.019, 1.128±0.062, 1.028±0.037, 0.96±0.07, 0.63±0.12, 1.17±0.13, 1.13±0.16, 1.11±0.11, and 0.98±0.06, 0.45±0.08, 1.13±0.05, 0.77±0.12, 0.51±0.13. Compared with those in burn serum alone group, the protein expressions of p-mTORC1, p-p70 S6K, and p-4E-BP1 of cells in normal serum group and each glycine group were significantly increased (P<0.05), while the protein expressions of p-AMPK were significantly decreased (P<0.05). Compared with those in 0.8 mmol/L glycine group, the protein expression of p-4E-BP1 of cells in 1.2 mmol/L glycine group and the protein expressions of p-mTORC1 and p-4E-BP1 of cells in 1.6 mmol/L glycine group were significantly decreased (P<0.05). Compared with those in 1.2 mmol/L glycine group, the protein expressions of p-mTORC1 and p-4E-BP1 of cells in 1.6 mmol/L glycine group were significantly decreased (P<0.05), while the protein expression of p-AMPK was significantly increased (P<0.05). Compared with those in normal serum group, the expression of tubulin of cells in burn serum alone group was significantly decreased at PIH 1.5, 3.5, and 6.5 (P<0.05), while the expression of HSP70 of cells at PIH 1.5 and 3.5 and the expression of MT at PIH 3.5 and 6.5 were significantly increased (P<0.05). The expressions of HSP70 and MT of cells at PIH 1.5, 3.5, and 6.5 and the expression of tubulin at PIH 1.5 and 3.5 in burn serum alone group and 0.8 mmol/L glycine+25 ng/mL rapamycin group were significantly lower than those in 0.8 mmol/L glycine group (P<0.05). At PIH 6.5, compared with that in normal serum group, the cell microtubule structure in burn serum alone group was disordered; the cell boundary in 0.8 mmol/L glycine group was clearer than that in burn serum alone group, and the microtubule structure arranged neatly near the nucleus. Compared with that in 0.8 mmol/L glycine group, 0.8 mmol/L glycine+25 ng/mL rapamycin group had unclear cell boundaries and disordered microtubule structure. Conclusions: Burn serum can cause cardiomyocytes damage in rats. Glycine can significantly up-regulate mammalian target of rapamycin/p70 ribosomal protein S6 kinase/eukaryotic translation initiation factor 4E-binding protein 1 signaling pathway through AMP-activated protein kinase, promote the synthesis of protective proteins HSP70, MT, and tubulin, stabilize the microtubule structure, and exert cardiomyocytes protection function.

[Standardized nomenclature of oral microorganisms in Chinese: the 2023 update].

Oral microbial community, as an important part of human microbial community, is closely related to oral and general health. Oral microbiological research has become the forefront of international microbiological research. Standardized and unified nomenclature for oral microorganisms in Chinese is of great significance to support the development of oral medicine research. Standardized translation of microbial names is the basis for writing canonical and authoritative professional textbooks and reference books, which helps students to accurately acquire the characteristics and classifications of oral microbes. Unified translation of oral microorganisms is also conducive to academic communication and cooperation, and plays an important role in oral health education and science popularization, which enables oral microbiology knowledge to be accurately disseminated to the public. Therefore, in order to standardize the words in scientific research, funding application, publications, academic exchanges and science popularization within the field of oral medicine, we have fully discussed and revised the Chinese names of oral microorganisms in 2017 edition and ones of newly discovered oral microbes, finally reaching a consensus to form the 2023 edition of Chinese names of oral microorganisms.

[Analysis the effect of cytokine-induced killer cells combined with mFOLFOX6 regimen in chemotherapy for advanced colorectal cancer].

Objective: To investigate the effect of cytokine-induced killer cells (CIK) combined with mFOLFOX6 regimen (fluorouracil+oxaliplatin+calcium folinate) on advanced colorectal cancer. Methods: 161 patients with advanced colon cancer admitted to the Fourth Clinical College of Xinxiang Medical College, Xinxiang Central Hospital of Henan Province from 2019 to 2021 were selected and divided into the study group (mFOLFOX6 regimen chemotherapy+CIK therapy) with 80 cases and the control group (mFOLFOX6 regimen chemotherapy) with 81 cases. The KPS score, median survival time, progression-free survival time, the proportion of Treg in peripheral blood mononuclear cells, the levels of CD4+, CD4+/CD8+, the expression levels of Foxp3 and CD127 mRNA, the quality-of-life score and the occurrence of toxic and side effects were compared between the two groups before and after chemotherapy. Results: The ages of patients in the study group and the control group were (64.8±7.5) and (66.1±7.0) years old, respectively, and the proportions of males were 62.5% (50 cases) and 50.6% (41 cases), respectively (both P values>0.05). After 2 cycles of chemotherapy and at the end of chemotherapy, the proportions of Treg, Foxp3 and CD127 mRNA in the study group were lower than those in the control group [2 cycles of chemotherapy: (4.33±0.86)% vs (4.89±1.20)%, (0.61±0.22) vs (0.73±0.20), (0.58±0.13) vs (0.70±0.15); after chemotherapy: (2.66±0.70)% vs (3.31±0.84)%, (0.43±0.18) vs (0.51±0.16), (0.41±0.10) vs (0.50±0.13)] (all P values<0.05). The KPS scores of the study group were higher than those of the control group [2 cycles of chemotherapy: (68.41±5.41) points vs (65.38±5.11) points; after chemotherapy: (72.08±5.94) points vs (67.95±5.51) points] (all P values<0.05). The median survival time of the study group was (16.8±2.2) months, which was higher than that of the control group [(11.2±1.8) months]. The progression-free survival time of the study group was also higher than that of the control group [(9.5±1.1) months vs (6.4±1.2) months], and the mortality rate was lower than that of the control group [11.3% (9 cases) vs 31.3% (25 cases)] (all P values<0.001). After chemotherapy, the scores of physical function, emotional function and role function in the study group were higher than those in the control group, and the scores of pains, fatigue and insomnia in the study group were lower than those in the control group (all P values<0.05). Conclusions: CIK combined with mFOLFOX6 regimen for advanced colorectal cancer can improve and regulate the immune function of patients, prolong the survival time of patients, and enhance the quality of life of patients.

[Selection of statistical methods for estimating the association between exposure factors and rare outcomes based on cohort studies].

Odds ratio (OR) and relative risk (RR) are the most commonly used statistical indicators for the estimation of the association between exposure and outcome. In the cohort study with rare outcomes, the estimated OR approximately equals RR, but RR seems more interpretable. The study aims to explore the difference between OR and RR estimated by different multivariate analyses to provide reference for the selection of more appropriate multivariate regression methods and reporting indicators for estimating the association between exposure and rare outcome in cohort studies. This case study used the data from China birth cohort study. Modes of conception and congenital disabilities were regarded as exposure and outcome, respectively. Maternal age, family history of congenital disabilities with clear evidence were included as covariates. Logistic regression, log-binomial regression, and Poisson regression were used to estimate the OR and RR, respectively. Then, OR, RR, and their 95%CI estimated by three regression models were compared. The OR estimated by logistic regression was approximately equal to the RR estimated by log-binomial regression or Poisson regression. However, the RR estimated by log-binomial regression or Poisson regression was closer to 1.00, with a narrower 95%CI. Log-binomial regression or Poisson regression might have non convergence or over dispersion problems. It is recommended to report the RR obtained by log-binomial regression or Poisson regression in the cohort study with rare outcomes if applicable.

[Toxic retinopathy caused by veterinary antiparasitic closantel: a case report].

A 32-year-old female patient presented with bilateral vision loss for 2 months following her intake of various antiparasitic drugs, including closantel, a veterinary drug, for a self-perceived intraocular parasitic infection. Swept-source optical coherence tomography revealed diffuse hyperreflectivity between the outer nuclear layer and the retinal pigment epithelium, as well as the largely indistinguishable outer retinal layers. This case was clinically diagnosed with veterinary closantel-induced toxic retinopathy and had a poor visual prognosis after nerve nutrition and circulation improvement therapy due to the long duration of the disease.
