Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective To compare the detection rate of right hemicolonic polyp between indigo carmine staining and white light endoscopy.Methods A total of 1052 patients with colonoscopic examination in Qing-baijiang District People's Hospital of Chengdu City from July 2022 to March 2023 were selected as the study subjects and divided into the indigo carmine staining group and white light endoscopy group,526 cases in each group.The right hemicolon was observed by indigo carmine staining and white light pattern respectively.The difference in the detection rate of right hemicolonic polyp was compared between the two detection methods. Results Compared with the white light endoscopic examination group,the detection rate of the right hemico-lonic polyp (41.6％),detection rate of the right hemicolon adenoma (20.9％),detection rate of wide basal ser-rated lesion (2.1％),detection rate of proliferative polyps (20.3％),detection rate of Paris type 0-Ⅱ (38.0％),detection rate of NICE 1 type (pale lesion,22.2％),detection rate of polyps with a diameter<5 mm (30.5％) and the consistency rate of pathological biopsy (86.4％),specificity (84.7％) and sensitivity (88.2％) in the indigo carmine staining group were higher,and the differences were statistically significant (P<0.05).There was no statistical difference in the duration of mirror withdrawal between the white light endoscopy group and the indigo carmine staining group (t=1.407,P=0.160).Conclusion The endoscopic examination with indigo carmine staining has a higher detection rate for right hemicolonic polyp,and is easier to detect micropolyps and flat polyps with pale color.

Objective To explore the clinical efficacy of high hip center technique total hip arthroplasty(THA)for CroweⅡ and Ⅲ developmental dysplasia of hip(DDH)and severe hip osteoarthritis(HOA).Methods From January 2018 to Jan-uary 2020,74 patients with Crowe type Ⅱ and Ⅲ DDH and severe HOA were admitted,and 37 cases of anatomical hip center reconstruction were taken as control group,including 7 males and 30 females,aged from 42 to 65 years old with an average of(58.40±4.98)years old,body mass index(BMI)ranged from 18 to 29 kg·m-2 with an average of(23.02±2.21)kg·m-2.Thirty-seven routine high hip center technical reconstruction were performed as study group,including 5 males and 32 females,aged from 41 to 65 years old with an average of(57.31±5.42)years old,BMI ranged from 18 to 29 kg·m-2 with an average of(23.14±2.07)kg·m-2.The patients presented with hip pain,limited function and range of motion,and gait instability before surgery.All patients underwent THA,the control group underwent intraoperative anatomical hip center reconstruction,and the study group underwent intraoperative high hip joint reconstruction.The perioperative indicators of the two groups were com-pared.The hip joint function,balance function and gait of the patients were evaluated before surgery,3 months,6 months,and 12 months after surgery.The length difference of both lower limbs,horizontal distance of rotation center,vertical distance of ro-tation center and femoral eccentricity were measured before operation and 1 year after operation.The incidence of complica-tions in the two groups during the operation and postoperative follow-up was counted.Results The operation time of the study group was shorter than that of the control group,and the intraoperative blood loss was less than that of the control group(P＜0.05).After 12-months follow-up,1 was lost to followvup in study group and 2 were lost to follow-up in control group.The Har-ris scores and Berg balance scale(BBS),pace,stride frequency and single step length in the study group were higher than those in the control group at 3 months and 6 months after operation(P＜0.05);there was no statistically significant difference between the two groups in the indexes 12 months after operation(P＞0.05).The vertical distance of the center of rotation of the study group was greater than that of the control group 12 months after operation(P＜0.05),and there was no significant difference in the length difference of the lower limbs,the horizontal distance of the center of rotation,and the femoral eccentricity between two groups(P＞0.05).There were no complications in either group.Conclusion The long-term effects of TH A in patients with DDH and severe HO A were similar between the two central hip reconstruction methods,and the safety was good,and the high hip central reconstruction technique could shorten the operation time and reduce the amount of intraoperative blood loss.At the same time,it has certain advantages in early recovery of hip joint function,balance function and walking function of patients.

Background/Aims: This study aims to evaluate the effects of acute codeine administration on primary and secondary esophageal peristalsis in patients with ineffective esophageal motility (IEM). Methods: Eighteen IEM patients (8 women; mean age 37.8 years, range 23-64 years) were enrolled in the study. The patients underwent highresolution manometry exams, consisting of 10 single wet swallows, multiple rapid swallows, and ten 20 mL rapid air injections to trigger secondary peristalsis. All participants completed 2 separate sessions, including acute administration of codeine (60 mg) and placebo, in a randomized order. Results: Codeine significantly increased the distal contractile integral (566 ± 81 mmHg · s · cm vs 247 ± 36 mmHg · s · cm, P = 0.001) andshortened distal latency (5.7 ± 0.2 seconds vs 6.5 ± 0.1 seconds, P < 0.001) for primary peristalsis compared with these parameters after placebo treatment. The mean total break length decreased significantly after codeine treatment compared with the length after placebo (P= 0.003). Codeine significantly increased esophagogastric junction-contractile integral (P= 0.028) but did not change the 4-second integrated relaxation pressure (P= 0.794). Codeine significantly decreased the frequency of weak (P= 0.039) and failed contractions (P= 0.009), resulting in increased frequency of normal primary peristalsis (P < 0.136). No significant differences in the ratio of impaired multiple rapid swallows inhibition and parameters of secondary peristalsis were detected. Conclusions In IEM patients, acute administration of codeine increases contraction vigor and reduces distal latency of primary esophageal peristalsis, but has no effect on secondary peristalsis. Future studies are required to further elucidate clinical relevance of these findings, especially in the setting of gastroesophageal reflux disease with IEM.

Objective: To investigate the outcomes including major complications and prognosis of extremely preterm infants with gestational age ≤25⁺⁶ weeks. Methods: The cross-sectional study enrolled 233 extremely preterm infants with gestational age ≤25⁺⁶ weeks who were admitted to the Department of Neonatology of Shenzhen Maternity and Child Healthcare Hospital from January 2015 to December 2021. The clinical data including perinatal factors, treatments, complications, and prognosis were extracted and analyzed. These extremely preterm infants were also grouped according to gestational age and year of admission to further analyze their survival rate, major complications, causes of death, and long-term outcomes. The comparisons between the groups were performed with Chi-square test and Kruskal-Wallis. Results: Among these 233 extremely preterm infants, 134 (57.5%) were males and 99 (42.5%) females. The gestational age was (24.6±0.9) weeks, the birth weight was 710.0 (605.0,784.5) g, and the overall survival rate was 61.8% (144/233). Among the surviving extremely preterm infants, the earliest gestational age was 22⁺² weeks and the lowest birth weight was 390 g. There were 17.6% (41/233) of extremely preterm infants had treatment withdrawn and were discharged in line with the will of guardians. Among the rest 192 extremely preterm infants managed with aggressive treatments, 14 (7.3%) died in hospital and 34 (17.7%) had treatment withdrawn later due to severe complications. Of the 192 extremely preterm infants, 144 (75.0%) survived, and the survival rate increased year by year (χ²=26.28, P<0.001) while the mortality decreased year by year (χ²=14.09, P=0.027). Among the survivors, 20.8%(30/144) had no major complications, and the incidence of complications was also negatively related with the gestational age (χ²=7.24, P=0.044), and the length of invasive ventilation was negatively related to the gestational age (χ²=29.14, P<0.001). In the group of less than 23⁺⁶ weeks, all extremely preterm infants had one or more major complications. The follow-up were completed in 122 infants and revealed that delayed motor development, language retardation, and hearing and vision impairment accounted for 17.2% (21/122), 8.2% (10/122) and 17.2% (21/122), respectively. Conclusions: Extremely preterm infants with gestational age ≤25⁺⁶ weeks are difficult to treat, but the survival rate of infants undergoing aggressive treatments increases year by year. Although the prevalence of major complications is still high, most extremely preterm infants have acceptable prognosis during follow-up.

Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.

OBJECTIVE: The mode of human immunodeficiency virus (HIV) transmission via injection drug use (IDU) still exists, and the recent shift in IDU-related transmission of HIV infection is largely unknown. The purpose of this study was to analyze the spatiotemporal sources and dynamics of HIV-1 transmission through IDU in Guangxi. METHODS: We performed a molecular epidemiological investigation of infections across Guangxi from 2009 to 2019. Phylogenetic and Bayesian time-geographic analyses of HIV-1 sequences were performed to confirm the characteristics of transmission between IDUs in combination with epidemiological data. RESULTS: Among the 535 subjects, CRF08_BC (57.4%), CRF01_AE (28.4%), and CRF07_BC (10.7%) were the top 3 HIV strains; 72.6% of infections were linked to other provinces in the transmission network; 93.6% of sequence-transmitted strains were locally endemic, with the rest coming from other provinces, predominantly Guangdong and Yunnan; 92.1% of the HIV transmission among people who inject drugs tended to be transmitted between HIV-positive IDUs. CONCLUSION HIV recombinants were high diversity, and circulating local strains were the transmission sources among IDUs in Guangxi. However, there were still cases of IDUs linked to other provinces. Coverage of traditional prevention strategies should be expanded, and inter-provincial collaboration between Guangxi, Yunnan, and Guangdong provinces should be strengthened.
