The c-Jun N-terminal kinase （JNK） signaling pathway， a key member of the mitogen-activated protein kinase （MAPK） family， plays a central role in the pathogenesis and progression of central nervous system （CNS） diseases by regulating core biological processes such as apoptosis， inflammatory responses， synaptic plasticity， and autophagy. This article sorts out and analyzes relevant literature published domestically and internationally in recent years， summarizing the mechanisms of action of the JNK signaling pathway in common CNS diseases and the research progress in traditional Chinese medicine （TCM） interventions in CNS diseases through the regulation of the JNK signaling pathway. Studies have shown that active components of TCM， such as berberine， paeoniflorin， and astragaloside Ⅳ， as well as compound formulations like Heixiaoyao san， Ditan tang， and Buyang huanwu tang， can exert neuroprotective effects in various CNS disorders， including Alzheimer’s disease， Parkinson’s disease， cerebral ischemia-reperfusion injury， and epilepsy， by inhibiting the aberrant activation of the JNK signaling pathway， thereby alleviating neuroinflammation， oxidative stress， and neuronal apoptosis， while improving synaptic function and cognitive behavioral deficits， regulating autophagy， and maintaining blood-brain barrier integrity.

Objective To compare and analyze the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR) combined with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) combined with coronary artery bypass grafting (CABG) for the treatment of significant aortic stenosis (AS) and coronary artery disease (CAD). Methods The data of patients with significant AS and CAD who underwent surgical treatment at Central China Fuwai Hospital of Zhengzhou University from January 2018 to July 2023 were collected. These patients were divided into a TAVR+PCI group and a SAVR+CABG group according to the operation method. Propensity score matching (PSM) was used to select patients with close clinical baseline characteristics, and the early- to mid-term outcomes of the two groups were compared. Results A total of 272 patients were enrolled, including 208 males and 64 females, with a mean age of (64.16±8.24) years. There were 47 patients in the TAVR+PCI group and 225 patients in the SAVR+CABG group. After 1 : 1 PSM, 32 pairs were selected. There was no statistical difference in baseline data between the two groups (P>0.05). Compared with the SAVR+CABG group, the TAVR+PCI group had significantly shorter operative time, mechanical ventilation time, ICU stay, postoperative hospital stay, and less intraoperative bleeding, and significantly lower postoperative transfusion and complete revascularization rates (P<0.05). The differences in the rates of postoperative in-hospital death, myocardial infarction, stroke, or other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of moderate-to-severe perivalvular leakage, death, or readmission in the mid-term follow-up were not statistically significant (P>0.05). Conclusion In patients with significant AS and CAD, the early- and mid-term rates of death and complications are similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.

Objective To compare perioperative outcomes of minimally invasive aortic valve surgery by a right anterior minithoracotomy (RAMT) and conventional sternotomy. Methods A retrospective analysis of patients who underwent isolated aortic valve surgeries in Central China Fuwai Hospital of Zhengzhou University between May 2021 and August 2023 with a minimal incision via the RAMT approach (a RAMT group) or conventional incision via the full sternotomy approach (a conventional group). A propensity score matching analysis was performed to balance preoperative data and compare perioperative data of the two groups. Results There were 58 patients in the RAMT group, including 46 males and 12 females with an average age of (52.0±14.1) years; 128 patients were enrolled in the conventional group, including 87 males and 41 females with an average age of (60.0±12.4) years. After propensity-score matching, there were 51 patients in each group. The RAMT group had a longer average operation time, cross-clamping time and cardiopulmonary bypass time compared to the conventional group (all P<0.05). However, ICU length of stay, ventilator-assisted time and postoperative hospital stay were significantly shorter in the RAMT group (all P<0.05). Patients in the RAMT group had lower 24 hour chest drain output (P<0.05). RAMT was associated with a trend towards a lower blood transfusion rate in comparison to the sternotomy group, although this was not statistically significant (P>0.05). The occurrence of all-cause death, and perioperative complications was also similar in both groups (P>0.05). Conclusion RAMT has less trauma, faster recovery, less postoperative drainage, and shorter hospital stay than conventional approach. RAMT in patients undergoing isolated aortic valve surgery is a safe approach.

Objective:To evaluate the effect of intermittent fasting on postoperative cognitive function in aged rats and the role of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway in it.Methods:Eighty SPF healthy male Sprague-Dawley rats, aged 20 months, weighing 600-650 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), postoperative cognitive dysfuction (POCD) group (group P), intermittent fasting + POCD group (group IF+ P), and intermittent fasting+ JAK2/STAT3 signaling pathway agonist C-A1+ POCD group (group IF+ A+ P). IF+ P group and IF+ A+ P group underwent a 4-week intermittent fasting procedure: fasting for 24 h followed by free eating for 24 h, without limiting water intake throughout the entire process, in addition C-A1 100 μg/kg was intraperitoneally injected daily during intermittent fasting in IF+ A+ P group. Rats underwent exploratory laparotomy under sevoflurane anesthesia to prepare POCD models in P group, IF+ P group and IF+ A+ P group. Three days after surgery, open field tests were conducted to evaluate the autonomous motor function of rats, and Morris water maze tests were conducted to evaluate the cognitive function of rats on 3-7 days after surgery. After the Morris water maze tests, the rats were sacrificed and the hippocampal CA1 area was removed for determination of the expression of JAK2, phosphorylated JAK2 (p-JAK2), STAT3, and phosphorylated STAT3 (p-STAT3) (by Western blot) and contents of interleukin-6 (IL-6), IL-1β and tumor necrosis factor-alpha (TNF-α) (by enzyme-linked immunosorbent assay) and for microscopic examination of pathological changes of hippocampal CA1 region (using HE staining). Results:There was no statistically significant difference in the speed, distance and duration of stay at the center of the open field test among the four groups ( P>0.05). Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were increased ( P<0.05), and the pathological damage occurred in the hippocampal CA1 region in group P. Compared with P group, the escape latency was significantly shortened, the number of crossing the original platform was increased, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were decreased ( P<0.05), and the pathological damage in the hippocampal CA1 area was significantly alleviated in IF+ P group. Compared with IF+ P group, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were increased ( P<0.05), and the pathological damage in the hippocampal CA1 area was aggravated in group IF+ A+ P. Conclusions:Intermittent fasting can improve postoperative cognitive function in aged rats, and the mechanism may be related to inhibiting the JAK2/STAT3 signaling pathway and reducing the neuroinflammatory responses in the hippocampal CA1 region.

Objective:Exploring the clinical characteristics and treatment outcomes of tailgut cysts, and improving the understanding of this disease.Methods:A retrospective analysis of 42 patients with tailgut cyst surgically treated from Jan 2012 to Mar 2024 was conducted.Results:This study included 42 patients (28 females,14 males) with a median age of 51 (23-76)years old. Nineteen cases of perineal/abdominal pain, 13 cases of perianal swelling, 10 cases of perianal abscess, 7 cases of sacrococcygeal sinus, and 4 cases of anal mass were observed. These symptoms often occurred simultaneously. All 42 patients had lesions located behind the rectum, with a relative position to the coccyx (7 above the coccyx, 17 below the coccyx, 11 above and between the coccyx levels, and 7 horizontally).Tailgut cysts were located in the pelvic floor, with 3 cases above the levator ani muscle, 17 cases below the levator ani muscle, and 22 cases between the levator ani muscle levels. Forty-one cases were treated with posterior approach, and 1 case was treated with combined approach. Thirty-two were unilocular and 10 multilocular. Female patients with multiple compartments were significantly more common than males ( P<0.05), while tumor location, tumor size, recurrence, and malignancy were all independent of gender. After surgery, 8 cases (19％) experienced recurrences and 5 cases of malignant transformation patients had a long term multiple relapses. Conclusions:Tailgut cysts are rare,while women were common seen.Non-specific symptoms of pain in the perineum or abdomen, perianal swelling or abscess, are usually observed. In addition, multiple relapses could have malignant transformation. Surgical complete resection is the most reasonable treatment method and the appropriate surgical path should be selected based on the size, location, and relationship with adjacent tissues of the tumor.

Objective:To evaluate the role of ryanodine receptor 2 (RyR2) in postoperative cognitive dysfunction (POCD) in aged rats.Methods:Sixty SPF healthy male Sprague-Dawley rats, aged 20 months, weighing 600-650 g, were divided into 3 groups ( n=20 each) using a random number table method: control group (group C), POCD group (group P) and dantrolene group (group D). A rat POCD model was prepared by closed reduction and internal fixation of left tibial fractures with sevoflurane anesthesia in P and D groups. RyR inhibitor dantrolene 2 mg/kg was injected via a tail vein at 30 min before surgery in group D. Morris water maze tests were conducted on day 1 before surgery and day 7 after surgery to evaluate the cognitive function. An open field test was conducted to detect the spontaneous motor function starting from day 7 after surgery. The rats were sacrificed after the end of Morris water maze tests and hippocampal tissues were taken for determination of the expression of RyR2 and cleaved caspase-3 (by Western blot), apoptosis rate and cytoplasmic calcium ion concentrations (by flow cytometry) and for microscopic examination of the pathological changes in hippocampal CA1 area (using HE staining). Results:There was no significant difference in the speed, distance and duration of stay in the center in the open field test among the three groups ( P>0.05). Compared with group C, the escape latency was significantly prolonged after surgery, the number of crossing the original platform was reduced, the expression of RyR2 and cleaved caspase-3 was up-regulated, and the neuronal apoptosis rate and cytoplasmic calcium ion concentration were increased ( P<0.05), and the pathological changes were found in the hippocampal CA1 area in group P. Compared with group P, the escape latency was significantly shortened after surgery, the number of crossing the original platform was increased, the expression of RyR2 and cleaved caspase-3 was down-regulated, and the neuronal apoptosis rate and cytoplasmic calcium ion concentration were decreased ( P<0.05), and the pathological changes were significantly reduced in the hippocampal CA1 area in group D. Conclusions:RyR2 activation is involved in the process of POCD in aged rats, which may be associated with increased calcium overload-induced hippocampal neuronal apoptosis.

Objective This study aims to observe the clinical effect of bone plate reduction in combination with a re-sorbable plate on large mandibular cysts.Methods Between October 2017 and September 2022,patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study.Intraoral approach was performed for bone plate reduction.Cone beam computed tomography(CBCT)scan was reviewed at 3,6,and 9 months postoperatively to observe postoperative complications.Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure.Results Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated.The average thickness of the cortical bone on the labial and buccal sides was measured to be about(1.98±0.37)mm before surgery,with a mean value of(0.73±0.17)mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate.The cystic cavities were well re-vealed during the surgeries,which were completed suc-cessfully.Postoperatively,the wounds healed in one stage without infection.The percentages of cyst shrinkage were 20.01%,41.76%,and 73.41%at 3,6,and 9 months after surgery,respectively.Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software.The bone mineral densities of the adult bone were 313.78,555.85,and 657.45 HU at the 3,6,and 9 month time intervals,respectively.No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale.Conclusion Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial re-gion with the presence of cortical bone.

Objective To explore the effect of modified graded motor imagery(mGMI)on upper limb motor function for stroke pa-tients. Methods From June to December,2023,68 stroke patients from Zhejiang Tongde Hospital were randomly divided into control group(n=34)and mGMI group(n=34).Both groups received routine rehabilitation,and the control group received routine motor imagery,while mGMI group received mGMI,for four weeks.They were assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Action Research Arm Test(ARAT)and modified Barthel Index(MBI)before and after treatment. Results One case dropped down in mGMI group.The scores of FMA-UE,ARAT and MBI increased in both groups after treatment(t>3.448,P<0.01),and they were higher in mGMI group than in the control group(t>7.504,P<0.001). Conclusion mGMI is more effective on upper limb motor function and activities of daily living for stroke patients than routine motor imagery.

Objective:To explore and analyze the clinical features of patients with immunoglobulin (Ig)G4-related hepatobiliary-pancreatic disease and the independent factors affecting the prognosis of IgG4-related sclerosing cholangitis (IgG4-SC).Methods:The clinical data of 179 adult cases diagnosed with IgG4-related hepato-pancreato-biliary disease in the Division of Gastroenterology and Hepatology, Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2011 to December 2022 were retrospectively analyzed. Patients were divided into three groups: isolated IgG4-SC, IgG4-SC/type 1 autoimmune pancreatitis(type 1 AIP), and isolated AIP according to the clinical manifestations. Demographic characteristics, baseline biochemical immunological indexes, and imaging manifestations were analyzed. The treatment response rate and survival rate were compared. The COX proportional hazards model was used to analyze the independent factors related to prognosis.Results:The mean age of diagnosis of patients with IgG4-related hepatobiliary-pancreatic disease was 60.3±12.0 years. Males accounted for 74.9%, and the median follow-up time was 38 months. The 1-year clinical response rate of patients with isolated IgG4-SC was lower than that of IgG4-SC/AIP (67.9% vs. 91.7%, P=0.019), and the primary endpoint-free 5-year survival rate was significantly reduced (64.9% vs. 95.9%, P<0.001). COX regression analysis showed that having cirrhosis before treatment ( HR=6.708, P=0.004) and poor response after half a year of treatment ( HR=11.488, P=0.002) were independent risk factors associated with the occurrence of adverse events in hepatobiliary diseases among patients with IgG4-SC. Conclusions:The clinical response rate and survival rate of patients with isolated IgG4-SC are lower than those of patients with IgG4-SC/AIP. Patients with IgG4-SC who do not respond well at six months of treatment and who have progressed to cirrhosis before treatment are at significantly increased risk of adverse events.
