ObjectiveTo evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) for muscle atrophy in patients with immobilization after surgical fixation of foot and ankle fractures.MethodsThis was a two-arm randomized controlled trial wherein 80 patients were recruited and divided into control (n = 40) and intervention (n = 40) groups. The control group received conventional orthopedic treatment, whereas the intervention group received TEAS and conventional treatment. The intervention group received TEAS 3 times a week for 30 min each time for 8 weeks. The primary outcomes were muscle thickness (MT) and cross-sectional area (CSA) of the rectus femoris and gastrocnemius muscles, whereas the secondary outcome measure was echo intensity (EI). Data were collected before the fixation operations (baseline assessment) and 4 and 8 weeks after intervention.ResultsCompared with baseline, the MT and CSA were reduced in both groups by the end of treatment, whereas EI increased in both groups. At week 4, the reduction in the rectus femoris CSA in the intervention group was significantly lower than that in the control group (P = .02); however, the between-group differences in the MT and EI (all P .05) were not significant. No serious adverse events were observed in either group.ConclusionOur study showed that TEAS can improve muscle atrophy by attenuating the decline in the muscle CSA. Because this was only a pilot trial, subsequent studies will need longer follow-ups and larger sample sizes.

Objective:To explore the influencing factors for pneumonia occurrence within three months in patients undergoing partial laryngectomy combined with radiotherapy, and to construct a nomogram prediction model for the risk of pneumonia occurrence.Methods:A total of 165 patients with laryngeal squamous cell carcinoma who underwent partial laryngectomy combined with postoperative radiotherapy in the Affiliated Cancer Hospital of Zhengzhou University from 2017 to 2023 were divided into three groups: a group without pneumonia, a low risk pneumonia group, and a medium to high risk pneumonia group according to the occurrence of pneumonia. The receiver operating characteristic (ROC) curve was used to determine the optimal cutoff values of the mean dose to the larynx (Larynx-Dmean) and the mean dose to the pharyngeal constrictor muscles (PCM-Dmean) for predicting the occurrence of pneumonia. Logistic regression analysis was used to screen out the influencing factors of pneumonia within three months after partial laryngectomy combined with radiotherapy, and a nomogram prediction model was constructed.Results:Among the 165 patients, 59 were in the group without pneumonia, 60 were in the group with a low risk of pneumonia, and 46 were in the group with a medium to high risk of pneumonia. The overall incidence of pneumonia was 64.2% (106/165). ROC curve analysis showed that the area under the curve (AUC) of the Larynx-Dmean for predicting the occurrence of pneumonia was 0.876, and the optimal cutoff value was 60.8 Gy. When the Larynx-Dmean was >60.8 Gy, the incidence of pneumonia was 96.7%. The AUC of the PCM-Dmean for predicting the occurrence of pneumonia was 0.747, and the optimal cutoff value was 54.6 Gy. When the PCM-Dmean was >54.6 Gy, the incidence of pneumonia was 74.7%. The AUC of the Larynx-Dmean for predicting the occurrence of medium to high risk pneumonia was 0.987, and the optimal cutoff value was 68.2 Gy. When the Larynx-Dmean was >68.2 Gy, the incidence of medium to high risk pneumonia was 100.0%. The AUC of the PCM-Dmean for predicting the occurrence of medium to high risk pneumonia was 0.850, and the optimal cutoff value was 58.7 Gy. When the PCM-Dmean was >58.7 Gy, the incidence of medium to high risk pneumonia was 85.2%. Multivariate logistic regression analysis showed that the incidence of pneumonia was higher in patients with a history of smoking ( OR=1.54, 95% CI: 1.02-1.74), a higher smoking index ( OR=2.43, 95% CI: 1.16-7.59), a higher Larynx-Dmean ( OR=3.79, 95% CI: 1.25-6.49), and a higher PCM-Dmean ( OR=2.44, 95% CI: 1.53-3.16). A nomogram prediction model for the risk of pneumonia and medium to high risk pneumonia within three months after partial laryngectomy combined with radiotherapy was successfully constructed, with C indices of 0.78 and 0.98, respectively, which had good predictive performance and clinical efficacy. Conclusions:When the Larynx-Dmean was >60.8 Gy and the PCM-Dmean was >54.6 Gy for postoperative radiotherapy after partial laryngectomy, the possibility of pneumonia occurrence in patients within three months increased significantly. Smoking history, smoking index, Larynx-Dmean, and PCM-Dmean were independent influencing factors for the occurrence of pneumonia. The nomogram prediction model constructed based on this can guide clinicians to take intervention measures to prevent the occurrence of pneumonia in patients with laryngeal cancer.

Objective:To analyze the correlation between blood glucose index and peripheral neuropathy in type 2 diabetes patients under continuous blood glucose monitoring.Methods:A total of 110 patients with type 2 diabetes admitted to the Lu′an Hospital Affiliated to Anhui Medical University from November 2022 to January 2024 were retrospectively observed, and the blood glucose indexes of patients were monitored by continuous glucose meter [glucose time in range (TIR), mean blood glucose (MBG), estimated hemoglobin A 1c (eHbA 1c), blood glucose standard deviation (SD), coefficient of variation (CV), largest amplitude of glycemic excursions (LAGE), mean amplitude of glycemic excursions (MAGE), means of daily differences (MODD), etc ]. All patients with type 2 diabetes were grouped according to whether they had peripheral neuropathy or not, and were divided into the developing group and the non-developing group. General data and blood glucose indexes of the two groups were collected and sorted out. Receiver operating characteristic (ROC) curve was used to analyze the value of various blood glucose indicators in predicting peripheral neuropathy in patients with type 2 diabetes. Spearman correlation analysis was also used to evaluate the correlation between blood glucose index and peripheral neuropathy. Results:The disease course, TIR, MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD of the occurrence group were significantly different from those of the non-occurrence group (all P<0.05). By plotting the ROC curve, It was found that the area under the curve (AUC) of TIR, MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD predicting peripheral neuropathy in patients with type 2 diabetes were 0.942, 0.840, 0.705, 0.759, 0.819, 0.813, 0.857 and 0.677, respectively. The AUC of the combined prediction was 0.971(95% CI: 0.946-0.997), which was higher than that of the single indicator (all P<0.05). Spearman correlation assessment showed a negative correlation between TIR and peripheral neuropathy ( r=-0.738, P<0.05). MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD were positively correlated with peripheral neuropathy ( r=0.554, 0.376, 0.452, 0.490, 0.527, 0.625, 0.272, all P<0.05). Conclusions:Based on continuous blood glucose monitoring, the blood glucose index of type 2 diabetes patients is closely related to peripheral neuropathy, and the above blood glucose index can accurately predict peripheral neuropathy, providing a reference for reducing or preventing the occurrence of peripheral neuropathy.

OBJECTIVE To study the mechanisms and effect of sufentanil(SUF)on protection of sepsis-induced myocardial injury.METHODS The in vitro experimental models of sepsis-induced myocardial injury were estab-lished by using lipopolysaccharide(LPS).The myocardial H9C2 cells were divided into the Control group,the LPS group,the SUF-L group,the SUF-M group,the SUF-H group,the SUF-H-ComC group and the SUF-H-ML385 group;the LPS group,the SUF-L group,the SUF-M group,the SUF-H group,the SUF-H-ComC group and the SUF-H-ML385 group were the experimental groups.The cells from the experimental groups were respec-tively inoculated and incubated in culture media containing 25 mg/L of LPS,and the culture media were respec-tively added SUF with the terminal dose of 0,5,10,20,20 and 20 μmol/L;the culture media of the SUF-H-ComC was added ComC with the terminal dose of 10 μmol/L,and the culture media of the SUF-H-ML385 was added ML385 with the terminal dose of 5 μmol/L.The cells from the Control group were incubated in normal cul-ture media.The same amount of culture media and CCK-8 reagent without containing myocardial H9C2 cells were assigned as the blank group.The cell viability was determined by CCK-8 method,the levels of reactive oxygen species(ROS),malondialdehyde(MDA),lactate dehydrogenase(LDH),superoxide dismutase(SOD)and gluta-thione peroxidase(GSH-Px)were detected.The Fe2+level of the cells was detected by iron ion colorimetric meth-od.The levels of interleukin(IL)-1β,IL-6 and tumor necrosis factor-α(TNF-α)in supernatant fluid of the culture media were detected with the use of enzyme-linked immunosorbent assay.The expression levels of adenosine 5'-monophosphate-activated protein kinas(AMPK),phosphorylated-AMPK(p-AMPK),nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)were detected by means of Western Blot.RESULTS The cell viability of the LPS group was lower than that of the Control group;the levels of ROS,MDA,LDH,Fe2+,IL-1β,IL-6 and TNF-α of the LPS group were higher than those of the Control group;the levels of SOD and GSH-Px of the LPS group were lower than those of the Control group;the expression levels of p-AMPK/AMPK,Nrf2 and HO-1 proteins of the LPS group were lower than those of the Control group(P＜0.05).As compared with the LPS group,the cell viability of the SUF-L group,the SUF-M group and the SUF-H group was succes-sively increased,the levels of ROS,MDA,LDH,Fe2+,IL-1β,IL-6 and TNF-α were successively reduced,the levels of SOD and GSH-Px were successively elevated,and the expression levels of p-AMPK/AMPK,Nrf2 and HO-1 proteins were successively increased(P＜0.05).AMPK pathway inhibitor and Nrf2 pathway inhibitor could reverse the viability of SUF-affecting LPS-induced myocardial H9C2 cells,levels of ROS,MDA,LDH,Fe2+,SOD,GSH-Px,IL-1β,IL-6 and TNF-α and downregulated the expression levels of p-AMPK/AMPK,Nrf2 and HO-1 proteins(P＜0.05).CONCLUSION SUF can improve the sepsis-induced myocardial injury,and the mecha-nism may be associated with activation of AMPK/Nrf2/HO-1 signaling pathways,inhibition of ferroptosis,oxi-dative stress injury and inflammatory reactions.

Objective To establish a nomogram prediction model of hyperuricemia(HUA)onset risk in overweight and obese children and adolescents in order to provide reference for the prevention and treatment of HUA in this population.Methods The clinical data of 1 410 overweight and obese children and adolescents aged 6-17 years old visiting in this hospital from September 2021 to August 2022 were retrospectively analyzed.A total of 987 overweight and obese children and adolescents were randomly extracted according to a ratio of 7:3 to establish the model,and the remaining 423 cases were validated internally.Referring to the definition of high uric acid in"Zhu-futang Practical Pediatrics",the subjects were divided into high uric acid group and non-high uric acid group.The logis-tic regression analysis was used to analyze the influencing factors of HUA in overweight and obese children and adoles-cents.The nomogram model was constructed by using the R language.The area under the receiver operating character-istic(ROC)curve(AUC),decision analysis curve(DIC),clinical impact curve(CIC)and C-index were used to evalu-ate the predictive ability of the model,and the Bootstrap repeated sampling method(taking samples for 1000 times)was used for internal validation of the model.Results The results of multivariate analysis showed that the age(OR=2.324,95％CI:1.155-4.672,P=0.018),gender(OR=0.456,95％CI:0.256-0.810,P=0.007),triglycerides(OR=3.775,95％CI:2.321-6.138,P＜0.001),blood calcium(OR=26.986,95％CI:3.186-228.589,P=0.003)and blood creatinine(OR=1.047,95％CI:1.026-1.070,P＜0.001)were the influen-cing factors of HUA in overweight and obese children and adolescents.AUC of the ROC curve of the model was 0.840,the sensitivity was 0.786,the specificity was 0.762,the Youden index was 0.548,and the C-index was 0.840.The risk probability of DC A was 0.1-0.8,the net benefit rate of both models was＞0,AUC of ROC curve in the internal verification was 0.871.Conclusion The constructed nomogram in this study has a good predictive efficiency for the onset risk of HUA in overweight and obese children and adolescents,and may provide reference for the early diagnosis and treatment of this population.

Objective To screen the distribution frequency of Mur blood group among voluntary blood donors in Hezhou,Guangxi,and further analyze the molecular basis of of Mur antigen positive samples.Methods The Mur pheno-type of voluntary blood donors in Hezhou was serologically screened using microplate method,and the distribution frequency of Mur antigens in different ethnic groups was analyzed.Genetic typing was performed on these positive samples with PCR-SSP method to verify the accuracy of the serological method,and the genetic background was sequenced and analyzed.Re-sults Among 3 298 samples from voluntary blood donors in Hezhou,432(13.10%,432/3 298)were screened positive for Mur antigen,and PCR-SSP genotyping validation showed that all 432 samples were electrophoretic positive.Among them,the proportion of Han blood donors with positive Mur antigen was12.79%(331/2 587),Yao ethnic group was13.25%(64/483),Zhuang ethnic group was 16.51%(36/218),and no statistically significant difference was found in the three groups(P＞0.05).Further sequencing results showed that 428 samples were GYP(B-A-B)Mur,also known as GYP.Mur type(12.98%,428/3 298),the other 4 samples were GYP(B-A-B)Bun,also known as GYP.Bun type(0.12%,4/3 298).Conclusion The Mur blood type frequency is high in the voluntary blood donors in Hezhou,Guangxi,and is predominant characterized by GYP.Mur genotype.Due to ethnic integration,no significant difference was noticed in the frequency of Mur blood type distribution between Han,Zhuang and Yao population.Therefore,conducting extensive Mur blood group antigen and antibody testing in Hezhou is of great significance for ensuring clinical blood transfusion safety.

Objective To explore the correlation between polarization status of microglia/macrophages(MG/MP)in brain tissue and edema around hematoma in patients with acute cerebral hemorrhage.Methods A total of 52 patients with acute intracerebral hemorrhage admitted to Anyang People's Hospital from December 2020 to November 2022 were selected as the research subjects.All patients underwent craniotomy to remove hematoma,and the normal brain tissue in the cortical area that was not invaded by the hematoma and the fragmented brain tissue around the hematoma(brain tissue around the hematoma)on the surgical pathway were obtained.The expression levels of inflammatory factors such as interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),IL-10 and transforming growth factor-β(TGF-β)protein in brain tissue were detected by Western blot.The expression levels of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue were detected by fluorescence quantitative polymerase chain reaction.The levels of M1-type and M2-type MG/MP in brain tissue was detected by immunofluorescence confocal technique.CT images data of patients before operation were collected and the relative-erihema-tomal edema(r-PHE)was calculated.The patients were divided into high r-PHE group(2.0≤ r-PHE＜2.5)and low r-PHE group(1.5＜r-PHE＜2.0)according to r-PHE.The relative expression of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue around the hematoma of patients between the high r-PHE group and the low r-PHE group was compared.Results The relative expressions of IL-1 β,IL-6,TNF-α protein and mRNA in brain tissue around the hematoma were significantly higher than those in the normal brain tissues(P＜0.05),but there was no significant difference in the relative expressions of IL-10 and TGF-β protein and mRNA between the brain tissue around the hematoma and the normal brain tissue(P＞0.05).The levels of M1 type and M2 type MG/MP in the brain tissue around the hematoma were significantly higher than those in normal brain tissue(P＜0.05).The relative expressions of IL-1β,IL-6 and TNF-α mRNA in the brain tissue around the hematoma of patients in the high r-PHE group were significantly higher than those in the low r-PHE group(P＜0.05),and there was no significant difference in the relative expressions of TGF-β and IL-10 mRNA in the brain tissue around the hematoma of patients between the two groups(P＞0.05).Conclusion The levels of pro-inflammatory factors and M1-type MG/MP are increased in the brain tissue around the hematoma in patients with acute cerebral hemorrhage,and the degree of polarization of M1-type MG/MP is consistent with the degree of edema around hematoma after cerebral hemorrhage.
