Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.

Objective:To investigate the efficacy and safety of transurethral incision for the treatment of ureterocele in infants.Methods:A retrospective analysis of 28 cases of ureterocele admitted from March 2012 to May 2023 were reviewed, all of which were less than 1 year old, 16 male and 12 female, with an average age of(5.7±3.5)months. The ureterocele was located on the left side in 8 cases, on the right side in 15 cases, and bilaterally in 5 cases. There were 12 cases of single system ureterocele, of which 7 cases were unilateral and 5 cases were bilateral. Duplex system ureterocele was observed in 16 cases, all of which were unilateral. Clinical manifestations: urinary tract infection in 13 cases, 11 cases of ureterocele or hydronephrosis and ureteral dilation were found during antenatal examination, and 4 cases of ureterocele were found after birth. Urological ultrasound, intravenous pyelography(IVP) and voiding cystourethrography(VCUG) were performed in all children, and 17 cases underwent magnetic resonance urolography (MRU), and confirm the diagnosis of ureterocele preoperatively. All of the cases were performed the transurethral incision.The ureterocele was punctured and incised 1-2 mm at the base of the bulge, and 2-4 points were punctured according to the bulge atrophy. Bilateral ureteroceles were punctured and incised simultaneously. Postoperative urine routine test, urinary tract color ultrasound and VCUG were performed to determine if there is urinary tract infection, hydronephrosis, ureteral dilation and bulging, and whether a second surgery is needed.Results:All operations were conducted successfully. The intraoperative bleeding was less than 3 ml and no intraoperative complications. The operative time was (28.4±10.3) min. The median postoperative follow-up was 34 (32, 36) months. Six cases underwent postoperative VCUG examination. Eleven children were recovered well with single systemic ureterocele. One child developed grade Ⅳ vesicoureteral reflux(VUR)and combined with bladder diverticulum, and ureterocele underwent open diverticulotomy and ureteral reimplantation six months after surgery. Nine children were recovered well with duplex systemic ureterocele. Six cases of children developed infection, of which 2 cases had an infection once within one month after TUI, and the other four cases still had intermittent infections after six months and VCUG was performed, and one case showed grade Ⅲ VUR of the lower ureter, which was observed conservatively, while the other three cases had enlarged cysts but no VUR, and upper heminephrectomy was performed, and the patients recovered well after surgery. Except for these 6 exceptions, in another case, after ten years of follow-up, the ureterocele became larger but no VUR, and the results were good after a second transurethral incision. There was no significant difference in the postoperative infections, new VUR cases, and secondary surgeries between the two groups.Conclusions:Transurethral incision has good surgical effect on children with single system ureterocele and duplex system ureterocele, and has advantages of easy operation, less trauma, safety and effectiveness, and few complications. It deserves to be recommended as the treatment of choice, especially for infants and young children.

Objective To explore the mechanism of Wenyang Yiqi Huoxue Prescription(WYYQHXP)in the treatment of chronic heart failure(CHF)by regulating miR-126-3p and PI3K/Akt signaling pathway based on network pharmacology and experimental studies.Methods Active components and targets of WYYQHXP were obtained through TCMSP,SwissTargetPrediction,SwissADME and PubChem.Four miRNA databases were used to obtain miR-126-3p targets,and four disease databases were used to obtain CHF related targets.The intersection of the three was taken as the potential target of action;the protein-protein interaction network relationships of potential targets were explored using STRING and Cytoscape 3.9.1 software,and the main active components and core targets were screened;GO and KEGG pathway enrichment analysis was performed using R 4.2.1 software;Molecular docking was performed on the main active components with the core targets.Isoproterenol was used to induce a rat model of CHF with qi deficiency and blood stasis syndrome,and intervened with WYYQHXP.MiR-126-3p and core target expression in coronary endothelial cells were detected by immunohistochemistry,RT-qPCR,and Western blot.Results Network pharmacology screened main active components of WYYQHXP,including β-sitosterol,doustanol,kaempferol,quercetin,baicalein and luteolin,and the core targets of EGFR,VEGFA and AKT1;KEGG was enriched to the signaling pathways such as PI3K/Akt,and the 3 core targets were distributed to the PI3K/Akt signaling pathway;molecular docking showed good binding ability of β-sitosterol and stigmasterol to three core targets.Animal experiments showed that WYYQHXP could increase left ventricular ejection fraction and left ventricular fractional shortening in model rats(P<0.01),reduce serum brain natriuretic peptide content(P<0.01),increase expression of miR-126-3p(P<0.05,P<0.01,P<0.001),the medium-dosage of WYYQHXP could increase mRNA and protein expressions of EGFR,PI3K,AKT1 and VEGFA in coronary endothelial cells(P<0.01).Conclusion WYYQHXP may activate PI3K/Akt signaling pathway by acting on miR-126-3p,thereby restoring endothelial dependent vasodilation of coronary arteries,repairing endothelial dysfunction of coronary arteries,and treating CHF.

Colorectal cancer （CRC） ranks as the second leading cause of cancer death worldwide. Although preventive colonoscopy screening has improved the survival rate of CRC patients in the past few years， there are still many patients diagnosed after symptoms appear. The surgery for CRC carries high risks and high recurrence， and ideal therapies remain to be developed. The Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway has become a focus of research due to its central role in cellular activities. As a classic oncogenic pathway， the JAK/STAT signaling pathway offers new possibilities for diagnosing and treating various malignancies， and it paves a new way for developing therapies for CRC. This pathway not only participates in basic cellular processes， such as proliferation， differentiation， and apoptosis but also plays a crucial role in immune responses and inflammation. Abnormal activation of the JAK/STAT signaling pathway is closely related to the occurrence and development of CRC. Studies have shown that the active components and compound prescriptions of traditional Chinese medicine （TCM） can inhibit the proliferation， invasion， migration， and angiogenesis while promoting the apoptosis and autophagy of CRC cells by interfering with the JAK/STAT signaling pathway. Furthermore， this pathway may also play a role in regulating the sensitivity of tumor cells to chemotherapy and radiotherapy， thus influencing the effectiveness of tumor treatment and impeding the progression of CRC. In recent years， research results have been updated rapidly， and previous literature summaries have failed to incorporate the latest findings， creating obstacles to accessing current literature. Therefore， this article supplements and summarizes information from the definition of the JAK/STAT pathway， association of this pathway with CRC， and TCM intervention of CRC. This review aims to provide references for future development of molecular biology regarding CRC and the research and development of new drugs.

Objective To explore the lung protective effect of pressure controlled ventilation-volume guaranteed(PCV-VG)combined with driving pressure(DP)guided lung protective ventilation strategy in patients undergoing thoracoscopic and laparoscopic radical esophagectomy.Methods 70 patients scheduled for elective thoracoscopic and laparoscopic radical esophagectomy were allocated into two groups using a random number table method:Conventional lung protective ventilation strategy group(group C)and DP guided lung protective ventilation strategy under PCV-VG mode group(group P),35 case in each group.Peak airway pressure(Ppeak),plateau pressure(Pplat),dynamic compliance(Cdyn)and DP were compared between the two groups at 5 minutes after intubation(T1),30 min after pneumoperitoneum established(T2),just prior to one lung ventilation(OLV)(T3),30 min after OLV(T4),60 min after OLV(T5)and 15 min from recovery of two lung ventilation(TLV)(T6).The blood pressure(BP),heart rate(HR),arterial partial pressure of oxygen(PaO2),partial pressure of carbon dioxide in arterial blood(PaCO2)and pH were recorded before anesthesia(T0),T2,T3,T4,T5 and T6 time points.The occurrence of postoperative pulmonary complications(PPCs)also recorded.Results Compared with group C,Ppeak in group P at T1,T2,T4,T5 and T6 time points was significantly decreased,and Cdyn was obviously increased,the differences were statistically significant(P＜0.05).At the T1,T4,T5 and T6 time points,the DP was lower in group P compared to group C,and Pplat at T6 time point was lower than that in group C,the differences were statistically significant(P＜0.05).At the time points of T4 and T5,the PaO2 in group P was higher than that in Group C,and the PaCO2 at T6 time point was also higher than that in group C,the differences were statistically significant(P＜0.05).The comparison of PaCO2 at T0,T2,T3,T4 and T5 time points of the two groups,the difference was not statistically significant(P＞0.05).Comparison of pH between the two groups,the difference was not statistically significant at all time points(P＞0.05).The systolic blood pressure(SBP)of group P was higher than that of group C at the T4 time point,and the diastolic blood pressure(DBP)was lower than that of group C at T6 time point,and the differences were statistically significant(P＜0.05);There were no significant differences in SBP and DBP at T0,T2,T3 and T5 time points,and HR at each time point between the two groups(P＞0.05).There was no statistically significant difference in the occurrence of PPCs within 7 d after operation between the two groups(P＞0.05).Conclusion DP guided lung protective ventilation strategy under PCV-VG mode can improve intraoperative respiratory mechanics,and increase oxygenation during OLV in patients undergoing thoracoscopic and laparoscopic radical esophagectomy,but it does not significantly affect the incidence of PPCs within 7 d after operation.It is worthy clinical significant.

Objective:To explore the early predictive value of the triglyceride-glucose (TyG) index and the controlling nutritional status (CONUT) score for severe acute pancreatitis (SAP).Methods:Clinical data from 1 050 hospitalized patients with acute pancreatitis (AP) at the General Hospital of Central Theater Command between January 2019 and December 2023 were retrospectively analyzed. Patients were categorized into mild acute pancreatitis (MAP) group ( n=606), moderately severe acute pancreatitis (MSAP) group ( n=320), and SAP group ( n=124) based on AP severity. General clinical data, laboratory parameters, modified computed tomography severity index (MCTSI), bedside index for severity in acute pancreatitis (BISAP), TyG index, and CONUT score were compared among the three groups. Spearman correlation analysis was used to evaluate the relationship between TyG index, CONUT score and AP severity. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for AP severity. Receiver operating characteristic curves (ROC) were plotted to calculate the area under the curve (AUC), sensitivity, and specificity for evaluating the predictive efficacy of TyG index, CONUT score, and their combination for SAP. Results:Significant differences on TyG index and CONUT score were observed among AP patients with varying severity (all P value <0.001). Spearman correlation analysis further revealed positive correlations of TyG index ( r=0.174), CONUT score ( r=0.306) with AP severity (both P<0.001). Multivariate logistic regression identified neutrophil count ( OR=1.076, 95% CI 1.027-1.125), MCTSI ( OR=2.565, 95% CI 2.250-2.921), BISAP ( OR=3.522, 95% CI 2.726-4.549), TyG index ( OR=1.859, 95% CI 1.276-2.707), and CONUT score ( OR=1.155, 95% CI 1.035-1.288) as independent risk factors for AP severity. The combined predictive model equation was: -7.342+0.76×TyG+0.439×CONUT. ROC analysis showed that the AUC values of the TyG index, CONUT score, and the combined index (TyG index+CONUT score) were 0.583 (95% CI 0.529-0.637), 0.701 (95% CI 0.652-0.75), and 0.755 (95% CI 0.710-0.801), with sensitivities of 0.706, 0.677, and 0.742, and specificities of 0.884, 0.629, and 0.657, respectively (all P value <0.05). Conclusions:TyG index and CONUT score are positively correlated with AP severity and may serve as reliable predictors for SAP. Their combination could enhance the predictive accuracy for AP.

Objective:To explore feasible surgical options for management of persistent Müllerian duct syndrome (PMDS) in children.Methods:A retrospective case summary was made.The clinical data of 8 patients who were diagnosed with PMDS and treated at Shanxi Children′s Hospital from September 2011 to November 2020 were retrospectively reviewed.Of the 8 PMDS patients, 6 were sporadic cases, 2 were twins (monochorionic), with an age range from 1 year to 12 years.All cases had normal male external genital organs and a chromosomal karyotype of 46, XY.During the operation, the surgical plan was selected according to clinical classification, vas structure and the development of the initial uterus.After the operation, the Müllerian structure in the abdominal cavity and the testicular development of the children were followed up through color ultrasound at the outpatient department.Results:Four patients had oblique inguinal hernia, 3 had bilateral cryptorchidism, and 1 had transverse testicular ectopia.Müllerian inhibitory hormone (MIH) levels were significantly decreased in 5 cases and normal in 1 case.The other 2 cases were not tested for MIH.All bilateral gonadal biopsies were testicular tissue, but undifferentiated gonadal tissue was detected in 3 cases.Four cases underwent radical surgery after gonadal biopsy.Among these 4 children, 3 received one-stage radical operation, and 1 received repair of oblique hernia before the radical surgery.Three patients had a well-defined vas structure and underwent hysterectomy and bilateral orchidopexy; three patients had a vague vas structure and received orchidopexy with the uterus preserved; one case underwent hysterectomy, orchidopexy on one side and orchiectomy on the other side; one case had bilateral orchidectomy in Fowler-Stephens stage.All the 8 children were followed up for 2 to 12 years.Ultrasound showed that the descending testis was well developed, with no cryptorchidism retraction or hernia recurrence.No tumor was observed in the preserved uterus in the abdominal cavity.Conclusions:The plan for PMDS management in children should be determined based on its clinical classification.Gonadal biopsy is essential, and whether to remove the Müllerian structure depends on the vas structure and the development of the uterus.
