AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Sedentary bad habits and unhealthy diets in modern lifestyles have led to an upward trend in the incidence of obesity, and a series of diseases related to obesity have also gradually received attention.

Compared with before treatment,TCM syndrome score of 2 groups was decreased,JOA score was increased,serum PGE2,TGF-β1,MMP-2,HIF-1α,and IL-1β were decreased after treatment (P<0.05). After treatment,compared with control group,TCM syndrome score of experimental group was decreased,JOA score was increased,serum PGE2,TGF-β1,MMP-2,HIF-1α,and IL-1β were decreased (P<0.05). Conclusion Long-snake moxibustion combined with modified Duhuo Jisheng Decoction can significantly reduce the inflammatory response of patients with liver-kidney deficiency pattern of lumbar disc herniation,inhibit the secretion of pain mediators,improve lumbar function,and thus improve clinical efficacy.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective:To analyze the adverse psychological state and its influencing factors in patients with dysphagia after cerebral stroke.Methods:In this cross-sectional survey, 120 patients with dysphagia after cerebral stroke in the Department of Neurology, Stroke Center in Henan Provincial People′s Hospital from January 2021 to March 2022 were selected with convenience sampling method for questionnaire survey. The depression anxiety stress scale-21 (DASS-21), family adaption partnership growth affection resolve index (APGAR) and social support rating scale (SSRS) were used to evaluate the adverse psychological state, family care degree and social support in those patients. And general data of the patients were collected too. A total of 120 questionnaires were sent out and reclaimed, among them 116 were valid. One patient withdrew from the study on his own. Finally, 115 patients were included as research objects. Analysis of variance and LSD-t test were used to compare the adverse psychological state of patients with different characteristics, Pearson correlation analysis was used to analyze the correlation between adverse psychological state and family care and social support. The multivariate linear regression analysis was used to analyze the influencing factors of adverse psychological state in patients with dysphagia after cerebral stroke. Results:The total DASS-21 score in the 115 patients with dysphagia after stroke was (43.32±6.58) points, of which, it was (16.02±3.45) points in the depression dimension, (14.55±3.27) points in anxiety dimension, (12.75±4.01) points in stress dimension; the total score of APGAR was (5.15±0.87) points, the total score of SSRS was (28.75±5.16) points. Family care and social support were both negatively correlated with adverse psychological state in those patients ( r=-0.514, -0.433, both P<0.05). Marital status, per capita monthly income, number of complications, family care and social support were the influencing factors of adverse psychological state in patients with dysphagia after cerebral stroke (β′=0.501, -0.365, 0.234, -0.269, -0.372, all P<0.05). Conclusions:Patients with dysphagia after cerebral stroke have a higher degree of adverse psychological state. Marital status, per capita monthly income, complications, family care and social support can affect the mental health in those patients.

Objective:To analyze the duration of the second stage of labor without epidural anesthesia and its association with pregnancy outcome.Methods:This retrospective study involved 12 789 women who delivered without epidural anesthesia in the First Affiliated Hospital of Kunming Medical University from January 1, 2014 to December 31, 2017. These subjects were divided into primipara group (9 517 cases) and multipara group (3 272 cases). Demographic characteristics, maternal and neonatal outcomes and the duration of the second stage of labor were compared between the two groups using two independent samples t-test, Mann-Whitney U test and Chi-square test (Fisher's exact test). Differences in the maternal and neonatal outcomes were also analyzed among different subgroups in primiparae [length of second stage: <1 h group ( n=6 265), ≥1-2 h group ( n=2 305), ≥2-3 h group ( n=831) and ≥3 h group ( n=116)] and multiparae [length of second stage <1 h group ( n=3 144), ≥1-2 h group ( n=102) and ≥2 h group ( n=26)]. The association between second stage length and pregnancy outcomes was analyzed with Cramer's V. After adjusted for maternal age, gestational weeks at delivery, body mass index before pregnancy, complications during pregnancy and neonatal birth weight, the relationship between the duration of the second stage and adverse outcomes was analyzed by binary logistic regression analysis. Results:The 95 th percentile of the second-stage labor duration was 143 min for primiparae and 52 min for multiparae. The rates of vaginal delivery, forceps delivery, cesarean section in the second stage, episiotomy, third- or fourth-degree perineal laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion, umbilical arterial blood gas pH<7.15 and transferring to neonatal intensive care unit (NICU) were all correlated with the duration of second stage in primiparae (Cramer's V values: 0.22, 0.23, 0.03, 0.22, 0.05, 0.10, 0.03, 0.03, 0.03 and 0.07, respectively, all P<0.05), and so did those of vaginal delivery, forceps delivery, episiotomy, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion and transferring to NICU in multiparae (Cramer's V values: 0.18, 0.19, 0.28, 0.14, 0.09, 0.13 and 0.06, respectively, all P<0.05). Logistic analysis showed that in primiparae, the duration of second stage >1 h was an independent risk factor for episiotomy, third- or fourth-degree perineum laceration, forceps delivery, postpartum hemorrhage, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 2.080 (1.907-2.268), 1.773 (1.080-2.911), 1.625 (1.420-1.859), 1.365 (1.231- 1.514), 1.305 (1.165-1.462) and 1.246 (1.081-1.436), respectively], while second stage length >2 h was the independent risk factor for episiotomy, forceps delivery, third- or fourth-degree perineum laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, blood transfusion, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 4.844 (4.132-5.678), 4.223 (3.571-4.993), 3.289 (1.806-5.989), 1.952 (1.675-2.274), 1.781 (1.057-3.001), 1.654 (1.025-2.668), 1.682 (1.421-1.991) and 1.298 (1.039-1.620), respectively]. In multiparae, the length of second stage >1 h was an independent risk factor for episiotomy, blood transfusion, forceps delivery, postpartum hemorrhage and admission to NICU [adjusted OR (95% CI): 8.796 (5.717-13.534), 7.469 (2.874-19.411), 6.135 (3.217-11.699), 2.697 (1.624-4.477) and 1.814 (1.063-3.097), respectively], while the duration of second stage >2 h was the independent risk factor for episiotomy, third- or fourth-degree perineum laceration, blood transfusion, grade Ⅱ postpartum hemorrhage, forceps delivery and postpartum hemorrhage [adjusted OR (95% CI): 38.868 (14.948-101.063), 28.046 (2.780-282.490), 20.076 (5.384-74.866), 16.327 (3.406-78.274), 14.337 (5.351-38.411) and 9.036 (3.880-21.011), respectively]. Conclusions:The duration of the second stage of labor without epidural anesthesia is between that reported by Friedman and by Zhang. A prolonged second stage of labor may increase the risk of adverse pregnancy outcomes.

Objective:To investigate the effect of milk on sebum secretion in golden hamsters, and to explore its possible mechanism of action.Methods:Eighteen golden hamsters were randomly and equally divided into 3 groups: blank control group receiving no intervention, whole-milk group gavaged with whole milk, and skimmed-milk group gavaged with skimmed milk. The gavage feeding was performed at a dose of 2.5 ml twice a day for 4 consecutive weeks. The maximum transverse diameter and maximum longitudinal diameter of bilateral sebaceous gland spots were measured on days 0, 7, 14, 21 and 28 after the start of intervention, and the area of sebaceous gland spots was calculated; at 24 hours after the last gavage, bilateral sebaceous gland spot tissues were resected, and subjected to immunohistochemical study to determine the expression of insulin-like growth factor-1 (IGF-1) /sterol regulatory element-binding protein-1 (SREBP-1) /acetyl-coenzyme A carboxylase (ACC-1) signaling pathway in sebaceous gland spots. Statistical analysis was carried out by using repeated measures analysis of variance, one-way analysis of variance for independent groups, Kruskal-Wallis H test, and least significant difference- t test for multiple comparisons. Results:Repeated measures analysis of variance showed that there was no significant difference in the area of sebaceous gland spots of golden hamsters among the 3 groups ( F= 0.96, P= 0.417) . The IGF-1 expression was significantly higher in the skimmed-milk group (0.39 ± 0.03) than in the blank control group (0.35 ± 0.03, t= 2.62, P= 0.021) and whole-milk group (0.33 ± 0.02, t= 3.82, P= 0.002) ; compared with the blank control group (0.36 ± 0.02) , the skimmed-milk group showed significantly increased SREBP-1 expression (0.42 ± 0.04, t= 2.64, P= 0.021) ; the ACC-1 expression was significantly higher in the skimmed-milk group (0.40 ± 0.03) and whole-milk group (0.40 ± 0.05) than in the blank control group (0.34 ± 0.03; t= 2.39, 2.47, P= 0.031, 0.026, respectively) . Conclusion:Milk may promote sebum secretion in golden hamsters through the IGF-1/SREBP-1/ACC-1 signaling pathway.

Objective:To explore the anti-inflammatory effect of pomegranate peel polyphenols on a rat auriclular model of acne and its mechanism of action.Methods:Totally, 36 specific-pathogen-free SD rats were randomly divided into 6 groups: blank group, model group, low-, medium- and high-dose pomegranate peel polyphenol groups and positive control group. In all groups except the blank group, 0.5 ml of 100% oleic acid was applied to the openings of bilateral auricular ducts once a day for 3 consecutive weeks, followed by subcutaneous injections of 50 μl of Propionibacterium acnes suspension at the oleic acid-applied sites once a day for 3 consecutive days, so as to establish a rat auriclular model of acne. After the model was confirmed to be successfully established by naked eyes, the low-, medium-, high-dose pomegranate peel polyphenol groups were topically treated with 0.5 mg of 1.4%, 2.8%, 5.6% (mass fraction) pomegranate peel polyphenol ointment respectively, the positive control group was topically treated with 0.5 mg of clindamycin hydrochloride gel, and the blank group and model group were topically treated with the same amount of distilled water. All the topical treatments were performed twice a day for 2 consecutive weeks. Twenty-four hours after the last topical treatment, abdominal aortic blood samples were collected, and enzyme-linked immunosorbent assay (ELISA) was conducted to detect the serum level of interleukin 17 (IL-17) in rats; rat auricular tissues were resected, hematoxylin-eosin (HE) staining was performed to observe histopathological changes of the skin tissues in each group, and immunohistochemical study to determine the expression of mammalian target of rapamycin (mTOR) , hypoxia-inducible factor-1α (HIF-1α) , and retinoic acid-related orphan receptor-γt (RORγt) in local tissues. Data meeting the assumptions of homogeneity of variances were analyzed by using one-way analysis of variance, and those that did not meet the assumptions of homogeneity of variances were analyzed by using Kruskal-Wallis H test; multiple comparisons were performed by using least significant difference- t test. Results:Compared with the model group, the pomegranate peel polyphenol groups and positive control group showed marked improvement in cysts, desquamation, crusts and epidermal keratinization, and reduced infiltration with inflammatory factors in the dermis at the modeling site. The serum level of IL-17 was significantly lower in the low-, medium- and high-dose pomegranate peel polyphenol groups (61.03 ± 5.99 ng/L, 55.35 ± 2.24 ng/L, 54.35 ± 4.29 ng/L, respectively) , positive control group (48.11 ± 4.07 ng/L) and blank group (42.10 ± 5.62 ng/L) than in the model group (70.24 ± 3.30 ng/L; t = 3.12, 5.34, 5.70, 8.29, 10.54, respectively, all P<0.05) . Immunohistochemical study revealed that the HIF-1α expression level was significantly lower in the low-, medium- and high-dose pomegranate peel polyphenol groups (0.29 ± 0.05, 0.29 ± 0.03, 0.33 ± 0.02, respectively) and positive control group (0.30 ± 0.01) than in the model group (0.41 ± 0.04; t = 4.89, 5.50, 3.62, 5.21, respectively, all P<0.05) ; the RORγt expression level was significantly lower in the low- and high-dose pomegranate peel polyphenol groups (0.28 ± 0.02, 0.31 ± 0.04, respectively) than in the model group (0.35 ± 0.02, t = 3.68, 2.18, respectively, both P<0.05) ; there was no significant difference in the mTOR expression level among these groups ( P = 0.119) . Conclusion:Pomegranate peel polyphenols could improve inflammatory reactions in the rat auriclular model of acne, which may be related to the down-regulation of HIF-1α/RORγt signaling pathway.

Multiple sclerosis (MS) is an idiopathic inflammatory demyelinating diseases of the central nervous system, the underlying cause of which has not been cleared. Previous studies have shown that the pathogenesis of MS is related to the destruction of blood brain barrier, furthermore the drugs used to treat MS have a certain protective effect on the function of blood brain barrier. Therefore, this review combines the research progress at home and abroad to clarify the relationship between the blood brain barrier and MS in pathogenesis and treatment, proposing possible orientation of development.
