OBJECTIVES: To explore the risk factors for malnutrition in patients with ulcerative colitis complicated with pyoderma gangrenosum and establish a nutritional risk prediction model for these patients. METHODS: A total of 277 patients with ulcerative colitis complicated with pyoderma gangrenosum treated from 2019 to 2024 were divided into malnutrition group (n=185) and normal nutrition group (n=92) according to whether malnutrition occurred. The data of 25 potential related factors pertaining to general demography, living and eating habits, and disease-related data were compared between the two groups. Lasso regression was used to screen the risk factors, and a nomogram model was established based on the screened factors and its prediction performance was assessed. RESULTS: The patients in the malnutrition group and normal nutrition group showed significant differences in 21 factors including gender, age, education level, BMI, place of residence, course of disease, and SAS language score (P<0.05). Lasso regression analysis identified 6 factors associated with malnutrition in these patients, namely the duration of ulcerative colitis, activity of ulcerative colitis, duration of pyoderma gangrenosum, number of chronic diseases, SAS score, and sleep quality. The nomogram prediction model established based on these 6 factors had an AUC of 0.992 (95% CI: 0.984-1.000) for predicting malnutrition in these patients, and its application in 14 clinical cases achieved an accuracy rate of 100%. CONCLUSIONS The duration of ulcerative colitis, activity of colitis, duration of pyoderma gangrenosum, number of chronic diseases, anxiety, and sleep quality are closely related with malnutrition in patients with ulcerative colitis complicated by pyoderma gangrenosum, and the nomogram prediction model based on these factors can provide assistance for predicting malnutrition in these patients.

This consensus provides a comprehensive overview of hair transplantation, covering preoperative preparation, surgical procedures, intraoperative coordination, postoperative management, and complication prevention and treatment. It serves as a key reference and guide for implementing standardized perioperative nursing care in FUE hair transplantation.

Objective To investigate the effects of high-definition transcranial direct current stimulation(HD-tDCS)on the modulation of the H-reflex and M-wave during ankle dorsiflexion-plantar flexion fatigue tasks to provide direction for the application of HD-tDCS in mitigating neuromuscular fatigue.Methods Twenty healthy young male participants were recruited and randomly assigned to either the real stimulation or sham stimulation group,with 10 participants in each group.The intervention consisted of a 5-day single-blind HD-tDCS application(duration:20 min;intensity:2 mA;target:Cz).Baseline measurements of the H-reflex and M-wave under resting conditions,M-wave during maximal voluntary isometric contraction(MVIC)of the dorsiflexor muscle,and MVIC torque of the dorsiflexor and plantar flexor muscles were obtained.An ankle dorsiflexion fatigue task was performed to determine the time to achieve fatigue for the task.The same fatigue task was repeated and evaluated one day after the intervention.A repeated-measures two-factor(stimulation condition x pre/post fatigue)analysis of variance(ANOVA)was used to analyze the effects of independent variables on the mechanical properties of the muscles and α-motoneuron conduction characteristics.Results After fatigue,voluntary activation(VA),maximal H-reflex(Hmax),maximal M-wave(Mmax),and dorsiflexor and plantar flexor MVIC torques in both groups were significantly reduced compared with pre-fatigue levels(P＜0.05).However,compared to the real stimulation group,the sham stimulation group showed a more significant decline in VA and plantar flexor MVIC torque(P＜0.05).Conclusions A continuous 5-day HD-tDCS intervention can effectively increase α-motoneuron activity at the spinal segment.It can also exert an inhibitory effect on reducing information transmission capacity at the peripheral neuromuscular junction under the ankle dorsi-plantarflexion fatigue task.

Aim To investigate the levels of a disintegrin and metalloprotease 10(ADAM-10)and soluble uro-kinase plasminogen activator receptor(suPAR)in the serum of hypertension patients with atherosclerosis and their relation-ship with the severity of disease.Methods From February 2021 to February 2023,125 hypertension patients with atherosclerosis who visited our hospital were collected as the study group,and 76 healthy people were collected as control group.The patients in the study group were grouped into mild group(n=40),moderate group(n=42)and severe group(n=43)according to the degree of atherosclerosis,after 60 days of treatment,the patients were grouped into a good prog-nosis group(n=74)and a poor prognosis group(n=51)based on their prognosis.Enzyme linked immunosorbent assay(ELISA)was applied to measure serum ADAM-10 and suPAR levels;Clinical data of patients with different prognosis were compared;Pearson method was applied to analyze the relationship between serum ADAM-10,suPAR levels and carotid in-tima-media thickness(IMT)in patients with hypertension and atherosclerosis;Multivariate Logistic regression was applied to analyze the influencing factors of poor prognosis in patients with hypertension and atherosclerosis;Receiver operating characteristic(ROC)curve was applied to evaluate the predictive value of ADAM-10 and suPAR alone and jointly for poor prognosis of hypertension with atherosclerosis.Results The levels of serum ADAM-10 and suPAR were significantly higher in the study group than those in control group(P＜0.05);The serum ADAM-10 and suPAR levels in moderate group and severe group were obviously higher than those in mild group(P＜0.05),while the serum ADAM-10 and suPAR levels were obviously higher in severe group than those in moderate group(P＜0.05);The serum ADAM-10 and suPAR levels,left and right IMT,systolic blood pressure,and diastolic blood pressure of patients with poor prognosis were signifi-cantly higher than those of patients with good prognosis(P＜0.05);Pearson correlation analysis showed that serum ADAM-10 and suPAR levels in patients with hypertension and atherosclerosis were positively correlated with systolic blood pres-sure,diastolic blood pressure and IMT(P＜0.001);Logistic regression analysis showed that the increased levels of systolic blood pressure,diastolic blood pressure,ADAM-10,suPAR and IMT were risk factors for poor prognosis of hypertension patients with atherosclerosis(P＜0.05);ROC curve analysis showed that the area under the curve(AUC)of serum AD-AM-10 and suPAR levels alone and jointly predicting poor prognosis of hypertension with atherosclerosis was 0.819,0.830 and 0.900,respectively,the combination of the two was superior to their individual predictions(Zcombination-AD AM-10=2.766,P=0.006;Zcombination-suPAR=2.602,P=0.009).Conclusion The levels of serum ADAM-10 and suPAR in patients with hypertension and atherosclerosis are significantly increased,and are positively correlated with the severity of atherosclero-sis.Both of them have a high predictive value for evaluating the prognosis of patients with hypertension and atherosclerosis.

Objective To summarize and explore the current state,hotspots,and trends in the field of surgical treatment for intracerebral hemorrhage(ICH)over the past decade through a bibliometric and visualization analysis of relevant literature.Methods Relevant Chinese and English literature on the surgical treatment of ICH,published from January 1,2014 to April 1,2024,was retrieved and screened from CNKI and Web of Science databases.Visualization analysis was conducted using CiteSpace,VOSviewer,and other software to analyze the number of published papers,authors,countries,institutions,etc.Social network analysis diagrams of authors,keyword clustering network analysis diagrams,keyword burst strength,and keyword timeline maps were also utilized.Results(1)A total of 3 456 relevant papers were included,with 2 173 in Chinese and 1 283 in English.From 2014 to 2021,the annual number of Chinese publications on ICH surgery was higher than that of English publications,but the number of Chinese publications began to decline from 2016.The number of English publications showed an overall increasing trend.(2)A total of 6 367 authors were identified from the English literature,with notable collaboration networks led by researchers such as Mocco J,Hanley DF,Ziai WC,You C,and Tang ZP.The Chinese literature included 6 522authors,with prominent collaboration networks led by Wang LK,Cai Q,Ku HB,Zhang S,and Zhu SQ.(3)Analysis of the countries involved in the English literature showed that 31 countries participated in research on ICH surgery,with China leading in the number of publications(505),followed by the United States(330)and Germany(106).The top three countries in centrality were the United States(0.32),China(0.16),and Canada(0.11).The top three institutions in English literature publications were Johns Hopkins University(51 papers),Ohio State University(39 papers),and Harvard University(38 papers).In China,Sichuan University(32 papers),Huazhong University of Science and Technology(30 papers),and Capital Medical University(27 papers)had multiple English publications;Wuhan University People's Hospital(15 papers),Affiliated Hospital of Guizhou Medical University(13 papers),and Affiliated Hospital of Yan'an University(13 papers)had multiple Chinese publications.There was close collaboration among research institutions in the English literature,whereas Chinese researchers often established research teams within their medical units with relatively less collaboration between teams.(4)Research on ICH surgery primarily focused on surgical methods,complications,and comprehensive perioperative treatment.Research hotspots included hypertensive ICH,minimally invasive surgical techniques,and perioperative management and treatment."neuroendoscopy"was the most recent emergent keyword in Chinese literature with high centrality and the strongest burst strength,while"randomized trial"had the highest burst strength in English literature.Research trends included the integration of artificial intelligence with minimally invasive techniques to optimize ICH surgery management and treatment strategies,analysis of risk factors,and evaluation of imaging value.Conclusions Over the past decade,the overall publication volume on the surgical treatment of ICH has been in a stable development phase,with research directions covering surgical techniques,diagnosis and treatment,evaluation,and management.Core research teams led by key authors were the main contributors to the publications.Future research hotspots and trends in ICH surgery may include the optimization of surgical techniques,complication management,large-scale multicenter clinical trials and integration of artificial intelligence with minimally invasive techniques.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective:To investigate the effect and mechanism of Myosin X on the radiosensitivity of non-small cell lung cancer (NSCLC) cell line H1975 in vitro. Methods:Western blot was applied to detect the expression level of Myosin X expression. The H1975 cell line with stable knockout of Myosin X (KO group) and infected with control virus (NC group) were constucted by using CRISPR/Cas9 technique. The knockout efficiency was validated. The radiosensitivity of two cell lines was measured by colony formation assay and single-hit multi-target model. γ-H 2AX focus formation test and RNA sequencing (RNAseq) analysis were employed to identify the regulatory mechanism of the radiosensitivity of lung cancer cell lines mediated by Myosin X. Results:The expression level of Myosin X in the H1975 cells was significantly up-regulated than those in other NSCLC cell lines (all P<0.01). The lentiviral vector of Myosin X sgRNA-Lenti-CRISPR v2 was successfully constructed. After the puromycin screening, H1975 cell lines with complete knockout of Myosin X and control cell lines (NC group) were obtained. Colony formation assay demonstrated that compared with the NC group, the radiosensitivity in the KO group was significantly higher (The D 0 value was decreased from 1.28 Gy to 1.03 Gy, SF 2 decreased from 0.29 to 0.21, and the sensitization ratio was 1.24). The γ-H 2AX focus formation test showed that the number of damage focus formed at 1 h and 6 h after irradiation in the KO group was significantly larger than that in the NC group ( P<0.05. RNAseq analysis indicated that the expression level of ISLR in the KO group was significantly down-regulated than that IN the NC group ( P<0.05). Conclusion:Knockout of Myosin X can increase the radiosensitivity of H1975 cells probably by interfering the repair of DNA double-strand damage and down-regulating the expression level of ISLR.

Objective: To investigate postoperative recurrent pattern of the thoracic esophageal squamous cell carcinoma (TESCC), aiming to provide a basis for the delineation of postoperative radiotherapy volume for TESCC. Methods: Clinical data of 66 TESCC patients who recurred after the radical esophagectomy in Zhongnan Hospital of Wuhan University from 2011 to 2017 were retrospectively analyzed. According to the AJCC 8^th edition-defined classification of esophageal carcinoma, regional lymph node stations 1 to 8M were defined as the upper-middle mediastinum region (UMMR), and stations 8Lo, 9 and 15 were defined as the inferior mediastinum region (IMR), stations 16 to 20 were regarded as the upper abdominal lymph node region (UAR). Results: Among all 66 patients, 41 cases (62%) experienced loco-regional recurrence alone, 25 cases (38%) presented with distant metastasis alone. A total of 54 patients with 148 lymph node recurred after treatment. The highest risk region of lymph node recurrence was UMMR (118/148, 80%), after that, followed by UAR (24/148, 17%). With regard to 9 cases of UAR, 6 patients had lower TESCC, and 8 patients (89%) were graded as ≥ pathological stage Ⅲ. Conclusions The highest risk region of lymph node recurrence is UMMR in TESCC patients undergoing radical esophagectomy, which should be considered as the target volume in postoperative radiotherapy. For patients with lower TESCC ≥ pathological stage Ⅲ, UAR might be the target volume with cautions. Anastomosis and IMR are probably not the routine treatment volumes.

Objective To investigate the short-term clinical outcome of one-level degenerative diseases for a single surgeon during his initial phase of performing a minimally invasive surgery oblique lumbar interbody fusion (OLIF) on the basis of perioperative parameters and follow-up data.Methods A prospective analysis of 49 consecutive patients that underwent a OLIF between November 2014 and March 2016 by corresponding author was performed.Only those patients that were single level,index surgeries were included.Every patient had a diagnosis of degenerative lumbar diseases including lumbar spondylolisthesis (25 cases),discogenic low back pain (14 cases) or segmental instability (10 cases).Patients underwent an indirect decompression and fusion using an expandable tubular retractor and single intervertebral cage with bilateral percutaneous pedicle screw fixation.49 patients were divided into the A group (the first 24 patients) and the B group (25 patients after the initial 24 patients).The following data were compared between the two groups:surgical time for Skin-Skin (minutes),estimated blood loss (ml),radiograph exposure time (seconds),the clinical and radiographic results,and intra-/postoperative complications.All intraoperative parameters only included the measurement and findings related with the OLIF procedure.The short-term clinical outcome of single level degenerative lumbar diseases treated by OLIF was assessed on the basis of follow-up data.The learning curve was measured using a logarithmic curve-fit regression analysis.Results Average operative time was significantly longer in the A group 47.1±10.6 min compared with the B group 37.2± 10.0 min.In comparison with the B group,the A group had significantly more X-ray exposure time (25.3±6.1 s versus 17.1±6.9 s).The operative and X-ray exposure time gradually decreased as the series progressed,and an asymptote was reached after about 20 cases.There was no statistically significant difference in intraoperative blood loss between the A group (28.1± 18.2) ml and the B group 24.4± 10.9 ml.The most observed complication was donor site pain (11 cases,45.8％),followed by thigh numbness/pain (5 cases,20.8％) and psoas/quadriceps weakness (2cases,8.3％),paralytic ileus (one case,4.2％) and sympathetic nerve injury (one case,4.2％) in the A group.Donor site pain occurred in four patients (16.0％),thigh numbness/ pain in three patients (12.0％),psoas/quadrieeps weakness in one patient (4.0％) and sympathetic nerve injury in one patient (4.0％) in the B group.All complications were transient and resolved within 3 months.The incidence of complications excluding donor site pain in the early period (A group) and the later period (B group) was 37.5％ and 20.0％,respectively,although there were no significant differences in perioperative complications between both groups.Forty nine patients were followed up for more than 1 year,and the average follow-up period was 18.5±3.9 months.The back pain VAS and ODI scores decreased respectively from 6.4±2.3 before surgery to 1.5±0.9 in final follow-up and from 37.1 ±9.4 before surgery to 11.8±3.9 in the last follow-up time.Total fusion rate was 89.8％ (44/49 cases)in final follow-up.Radiographic evaluation showed similar bony fusion in the A group (22 of 24 cases) with the B group (22 of 25 cases) in the last follow-up time.Conclusion Single level degenerative lumbar diseases can safely and effectively be treated by using OLIF with a good short-term clinical outcome.The procedure presents a learning curve to the practicing spine surgeon with regards to operative time,X-ray exposure time and intra-/postoperative complications.Intraoperative parameters improved with understanding the minimally invasive technique.Close attention to details can minimize complications that may be associated with the learning curve.

The Epstein-Barr virus (EBV) is a gamma herpes virus associated with several types of malignancies. The EBV encodes viral microRNAs (miRNAs) that can target genes within cells. The EBV participates in signal transduction as well as the proliferation and differentiation of cells. How the target genes and functions of EBV-encoded miRNAs contribute to the pathogenesis of EBV is an important research topic. Some target genes have been validated since EBV-encoded miRNAs were discovered and, in this article, we summarize them and their functions.
