Objective:To assess the efficacy and safety of pain control nursing for burn patients.Methods:Databases including CNKI, Wanfang Data Knowledge Service Platform, Weipu Database, China Biomedical Literature Database, Web of Science and Cochrane Library were searched to collect the literature on pain control nursing of burn patients from their inception to December 31, 2024. Literature screening, data extraction and quality assessment were performed independently by 2 researchers based on inclusion and exclusion criteria. Meta-analysis of the included studies was performed by applying RevMan 5.4 software. The efficacy of pain control care was assessed in terms of improving care satisfaction, alleviating negative emotions, reducing pain, and decreasing infection rate. Publication bias was analyzed on the related studies.Results:A total of 9 papers were included, all of which were randomized controlled trial (RCT) studies, involving 791 burn patients, with 392 in the pain control nursing group and 399 in the conventional care group. Meta-analysis showed that compared with the conventional care, pain control nursing significantly increased satisfaction of care ( OR=0.28, 95% CI 0.22, 0.34), improved negative emotions ( SMD=-3.06, 95% CI -4.65, -1.47), reduced pain ( SMD=-2.49, 95% CI -3.41, -1.58), and effectively reduced the incidence of infection ( OR=0.13, 95% CI 0.05, 0.34). The studies related to negative emotions were at the risk of publication bias. Conclusion:Compared with conventional care, pain control nursing can significantly increase care satisfaction, alleviate negative emotions, reduce pain, and lower infection risk in burn patients.

In recent years,cancer incidence has been rising.Chemotherapy is a key clinical treatment,yet long-term use of antitumor drugs can lead to multidrug resistance(MDR).This review introduces the causes and mechanisms of MDR,mainly including genomic mutations,cellular autophagy,tumor micro-environment,and apoptosis.Subsequently,the concept and mo-lecular mechanisms of Cuproptosis are introduced,pointing out that the abnormal accumulation of Cu2+in cells and the chain reaction triggered by the binding of excess Cu2+with mitochon-drial enzymes ultimately lead to cell death.Finally,copper ionophores,copper complexes as drugs,and strategies for indu-cing cuproptosis to reverse drug resistance are introduced.The prospects for exploring antitumor drugs that can reverse MDR are briefly discussed,bringing new ideas to overcoming tumor resist-ance.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Objective:To investigate the predictive value of neutrophil/lymphocyte ratio (NLR) on the discharge outcome in elderly patients with acute ischemic stroke (AIS) receiving intravenous thrombolysis (IVT).Methods:Elderly patients with AIS received IVT in the Department of Neurology, the Second Affiliated Hospital of Soochow University from August 2018 to August 2020 were retrospectively included. The modified Rankin Scale was used to evaluate discharge outcome, and the score >2 was defined as poor outcome. Symptomatic intracranial hemorrhage (sICH) was defined as any intracranial hemorrhage found on imaging examination accompanied by neurological deterioration, where the National Institutes of Health Stroke Scale (NIHSS) score increased by ≥4 from baseline or bleeding led to death. Multivariate logistic regression analysis was used to determine independent risk factors for sICH and poor discharge outcome. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of NLR for sICH and poor discharge outcome. Results:A total of 228 elderly patients with AIS receiving IVT were enrolled, including 118 males (51.8%), aged 73.64±8.16 years, with a baseline NIHSS score of 6.23±6.54. Ninety patients (39.5%) had poor outcome at discharge, and 16 (7.0%) developed sICH. Univariate analysis showed that the NLR in the poor outcome group was significantly higher than that in the good outcome group ( P<0.01). Multivariate logistic regression analysis showed that a higher NLR was an independent risk factor for poor discharge outcome (odds ratio [ OR] 1.245, 95% confidence interval [ CI] 1.044-1.484; P< 0.05) and sICH ( OR 1.124, 95% CI 1.010-1.251; P<0.05). ROC curve analysis showed that the area under the curve of NLR for predicting poor discharge outcome was 0.693 (95% CI 0.620-0.765; P<0.01). The optimal cutoff value was 4.345. Its corresponding sensitivity and specificity were 47.8% and 87.7%, respectively. The area under the curve of NLR for predicting sICH was 0.651 (95% CI 0.498-0.804; P<0.05). The optimal cutoff value was 3.515. Its corresponding sensitivity and specificity were 68.8% and 61.8%, respectively. Conclusions:A higher NLR is independently associated with sICH and poor discharge outcome in elderly patients with AIS receiving IVT, and have certain predictive value for sICH and poor discharge outcome.

Objective:To evaluate the efficacy of Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization in the treatment of tubal obstructive infertility of liver depression and qi stagnation type.Methods:A total of 60 patients with tubal obstructive infertility of liver depression and qi stagnation type who met the inclusion criteria were selected, between August 2018 and June 2020, and they were divided into the observation group with 31 cases and the control group with 29 cases, according to the random number table method. The control group was treated with hysteroscopic recanalization, while the observation group was given Chaichuan Tongren Mixture on the basis of the control group. Both groups were treated for 4 months and followed up for 12 months. TCM syndromes were scored before and after treatment, and prostaglandin E 2 (PGE 2) was detected by fully automatic biochemical analyzer and levels of TNF-α, CRP and IL-6 were measured by ELISA. The tubal patency of patients after treatment was observed, the pregnancy status was recorded after the end of follow-up and the clinical efficacy was evaluated. Results:The total effective rate was 96.77% in the observation group and that in the control group was 75.86% ( χ2=4.01, P<0.01). The scores of breast distending pain, irregular menstruation, dark purple menstrual flow and lumbosacral pain in the observation group after treatment were significantly lower than those in the control group ( t values were 17.69, 21.67, 20.89, 14.67, 18.20, respectively, all Ps<0.001). After treatment, the levels of serum PGE 2, TNF-α, CRP, and IL-6 were significantly lower in the observation group than those in the control group [(65.31±6.73) ng/L vs. (87.10±8.85) ng/L, t=10.78; (6.90±0.71) ng/L vs. (11.35±1.23) ng/L, t=17.30; (2.47±0.25) mg/L vs. (5.10±0.52) mg/L, t=25.23; (12.38±1.26) ng/L vs. (30.16±3.15) ng/L, t=29.05] ( P<0.01). After treatment, there was statistical significance in the total effective rate of tubal patency of 96.8% (30/31) in the observation group compared to 79.3% (23/29) in the control group ( χ2=4.43, P<0.01). At the end of follow-up, the pregnancy rate was 71.0% (22/31) in the observation group and 44.8% (13/29) in the control group, and the difference was statistically significant ( χ2=4.21, P<0.01). Conclusion:The Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization can reduce the levels of inflammatory mediators and increase the pregnancy rate of patients with tubal obstructive infertility of liver depression and qi stagnation type.

Inositol 1,4,5-trisphosphate receptor 1 (ITPR1) is an important intracellular channel for releasing Ca²⁺. In order to investigate the effects of the ITPR1 overexpression on Ca²⁺ concentration and lipid content in duck uterine epithelial cells and its effects on calcium transport-related genes, the structural domain of ITPR1 gene of duck was cloned into an eukaryotic expression vector and transfected into duck uterine epithelial cells. The overexpression of the ITPR1 gene, the concentration of Ca²⁺, the lipid content, and the expression of other 6 calcium transport-related genes was determined. The results showed that the concentration of Ca²⁺ in uterine epithelial cells was significantly reduced after transfection (P<0.05), the triglyceride content was significantly increased (P<0.01), and the high-density lipoprotein content was significantly decreased (P<0.01). The correlation analysis results showed that the overexpression of the C-terminal half of the ITPR1 gene was significantly positively correlated with the total cholesterol content (P<0.01), which was significantly positively correlated with the low-density lipoprotein content (P<0.05). The overexpression of the N-terminal half of the ITPR1 gene was significantly positively correlated with the triglyceride content (P<0.01), which was significantly negatively correlated with the concentration of Ca²⁺ (P<0.05). RT-qPCR results of 6 calcium transport-related genes showed that the overexpression of the C-terminal half of the ITPR1 gene significantly inhibited the expression of the IP3R2, VDAC2 and CAV1 genes, and the overexpression of the N-terminal half of the ITPR1 gene significantly promoted the expression of the IP3R3 and CACNA2D1 genes. In conclusion, the ITPR1 gene overexpression can promote Ca²⁺ release in duck uterus epithelial cells, promote the synthesis of triglyceride, low-density lipoprotein and cholesterol, and inhibit the production of high-density lipoprotein, and the ITPR1 gene overexpression affected the expression of all 6 calcium transport-related genes.

Objective To investigate the effects of transient receptor potential cation channel 6 (TRPC6) on the expression of nephrin, desmin and caspase 9 and on the apoptosis of podocytes in a mouse model of podocyte injury induced by TGF-β1.Methods Conditionally immortalized mouse podocytes were cultured in vitro and divided into four groups: control, TGF-β1 treatment, TGF-β1+PGPU6/GFP/Neo-TRPC6-mus-581 (TRPC6 knockdown) and TGF-β1+PGPU6/GFP/Neo-NC (negative control).Real-time RT-PCR and Western blot analysis were performed to detect the expression of nephrin, desmin and caspase 9 at mRNA and protein levels, respectively.Flow cytometry was used to analyze the apoptotic rate of podocytes.DAPI fluorescent staining was used to observe the morphological changes of apoptotic podocytes.Results Green fluorescent protein (GFP)-expressing podocytes at 48 hours after transfection were significantly more than those at 24 hours after transfection.The level of TRPC6 in mouse podocytes transfected with PGPU6/GFP/Neo-TRPC6-mus-581 was significantly decreased as compared with that of the control group (P<0.05).No significant difference in the expression of TRPC6 was observed between the negative control group and the control group.Compared with the control group, the TGF-β1 treatment group showed increased expression of desmin and caspase 9 at both mRNA and protein levels (P<0.01), but decreased expression of nephrin at mRNA and protein levels at 48 hours after TGF-β1 intervention (P<0.05).The up-regulated desmin and caspase 9 and the down-regulated nephrin induced by TGF-β1 could be inhibited by the means of TRPC6 knockdown.The apoptosis rate of podocytes in TGF-β1 treatment group was (14.0±2.1)%, while that in TRPC6 knockdown was (10.90±0.56)% (P<0.05).The apoptosis rate of podocytes in negative control group was higher than that in TGF-β1 treatment group (P>0.05).More apoptotic cells with typical morphological features of apoptosis were observed after exposure to TGF-β1 for 48 hours.Conclusion TGF-β1 could induce the apoptosis of podocytes, inhibit the expression of nephrin and enhance the expression of caspase 9 and desmin, the possible mechanisms of which may be related to TRPC6 signal pathway.These changes in TGF-β1-treated podocytes could be alleviated by inhibiting the expression of TRPC6, which might have a protective effect on podocyte injury.
