Objective:To investigate intraoperative pathological findings and the interventional effects of "deep cervical lymphaticovenous anastomosis+" (dcLVA+) on deep cervical lymphatic drainage as well as the blood flow of carotid artery and jugular vein in elderly patients with cognitive impairment, and to put forward the thoughts based on the findings from the surgery.Methods:Between May 2024 and December 2024, retrospective analysis of Microsurgery Hospital, Fengcheng Hospital, Xi'an Medical College performed dcLVA+ between the deep cervical lymphatics or lymph nodes and jugular veins in 50 elderly patients with cognitive impairment (19 males and 31 females, aged 55-88 years with 69.94 years in average). Nine patients were found with Clinical Dementia Rating (CDR) score at 1 (mild), 7 with CDR score at 2 (moderate) and 34 with CDR score at 3 (severe). Intraoperative observations based on literature reviews had identified anatomical relationships between the lymphatic sacs containing cervical lymphatic chain and the carotid sheath. The lymph node count, size, distribution, thickness of fat tissue and conditions of lymphatic vessels were documented. Ultrasound was used to compare the blood flow of carotid artery and jugular vein as well as the cross-sectional areas at the planes of hyoid and cricoid cartilage before and after the closure of incisions under anaesthesia in 39 patients. Correlation analyses for Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCa), Activities of Daily Living (ADL) and Agitation behavior score before and 1 week after surgery were performed using Spearman's correlation and Wilcoxon paired tests. P<0.05 was considered statistically significant. Postoperative follow-ups were conducted via the visit of outpatient clinic and WeChat and telephone interviews. Results:In surgery, the cervical lymphatic chain was found running within an almost enclosed sac surrounding the carotid sheath. There were enlarged lymph nodes, increased fat deposition, lymphatic dilation or fibrosis in the sac. The preoperative blood flow in the carotid artery at the planes of hyoid and cricoid cartilage in the 39 patients was recorded at 150.52 ml/min±40.33 ml/min and 358.29 ml/min±129.30 ml/min, while that in the jugular vein was at 172.50 ml/min±63.94 ml/min and 317.00 ml/min±105.21 ml/min, respectively, both were far lower than the normal blood flow. There were statistically significant differences in the blood flow of carotid artery and jugular vein before and after surgery ( P<0.01). It was found that the preoperative blood flow of the internal carotid artery at the plane of hyoid was positively correlated with the preoperative scores of MMSE ( P<0.01), MoCa ( P<0.05) and ADL ( P<0.01). The blood flow of the common carotid artery at the plane of cricoid cartilage was found significantly and positively correlated with the preoperative scores of MMSE ( P<0.05). It was also noted that the blood flow of the internal carotid artery at the plane of hyoid was significantly and positively correlated with the postoperative ADL ( P<0.01) but negatively correlated with the Agitation behavior score ( P<0.05). The blood flow of the common carotid artery at the plane of cricoid cartilage was significantly and positively correlated with the postoperative scores of MMSE and MoCa ( P<0.05). The blood flow of the internal jugular vein at the plane of hyoid was negatively correlated with the Agitation behavior score ( P<0.01). The cross-sectional area of carotid artery at the plane of left hyoid was significantly and positively correlated with the MMSE score ( P<0.05). Statistically significant differences were observed in MMSE, MoCa, ADL and Agitation behavior score before and after surgery ( P<0.01). Conclusion:dcLVA+ shows a certain therapeutic benefit to the elderly patients with cognitive impairment. The intraoperatively observed pathological changes in cervical lymphatic sacs affect deep cervical lymphatic drainage and the blood flow of carotid artery and jugular vein. Further studies are necessary to find out whether the findings from this study would be the specific pathological changes and the morbidity mechanisms among the elderly patients with cognitive impairment.

Objective This study investigated the regulatory effect of high mobility group protein B1 (HMGB1) in the peripheral blood of patients with primary immune thrombocytopenia (ITP) on myeloid dendritic cells (mDC) and Th17/regulatory T cells (Treg) balance. Methods The study enrolled 30 newly diagnosed ITP patients and 30 healthy controls.Flow cytometry was used to measure the proportion of mDC, Th17, and Treg cells in the peripheral blood of ITP patients and healthy controls. ELISA was conducted to quantify the serum levels of HMGB1, interleukin 6 (IL-6), IL-23, IL-17, and transforming growth factor β(TGF-β). The mRNA levels of retinoic acid-related orphan receptor γt(RORγt) and forehead box P3(FOXP3) were detected by real-time PCR. The correlation between the abovementioned cells, cytokines, and platelet count was assessed using Pearson linear correlation analysis. Results The proportion of Th17 cells and the expression levels of HMGB1, IL-6, IL-23, IL-17 and the level of RORγt mRNA in the peripheral blood of ITP patients were higher than those in healthy controls. However, the Treg cell proportion and TGF-β level were lower in ITP patients than those in healthy controls. In patients with ITP, the proportion of mDC and the level of FOXP3 mRNA did not show significant changes. The proportion of mDC cells was significantly correlated with the expression of IL-6 and IL-23. Moreover, the expression of HMGB1 showed a significant correlation with the expression of mDC, IL-6, IL-23, RORγt mRNA, and IL-17. Notably, both the proportion of mDC cells and the expression of HMGB1 were negatively correlated with platelet count. Conclusion The high expression of HMGB1 in peripheral blood of ITP patients may induce Th17/Treg imbalance by promoting the maturation of mDC and affecting the secretion of cytokines, thereby potentially playing a role in the immunological mechanism of ITP.

ObjectiveThis study aims to examine the effect of Rhei Radix et Rhizoma-Coptidis Rhizoma on reducing insulin resistance in db/db mice by regulating the adenylate activated protein kinase （AMPK）/UNC-51-like kinase 1 （ULK1）/key molecule of autophagy， benzyl chloride 1 （Beclin1） pathway and elucidate the underlying mechanism. MethodSixty 6-week-old male db/db mice were studied. They were randomly divided into the model group， metformin group （0.26 g·kg^-1）， and low-， middle-， and high-dose groups （2.25， 4.5， 9 g·kg^-1） of Rhei Radix et Rhizoma-Coptidis Rhizoma. A blank group of db/m mice of the same age was set， with 12 mice in each group. After eight weeks of continuous intragastric administration， the blank group and model group received distilled water intragastrically once a day. The survival status of the mice was observed， and fasting blood glucose （FBG） was measured using a Roche blood glucose device. Fasting serum insulin （FINS） was measured using an enzyme-linked immunosorbent assay， and the insulin resistance index （HOMA-IR） was calculated. Hematoxylin-eosin （HE） staining was performed to observe the pathological changes in the liver of the mice. The protein expression levels of AMPK， Beclin1， autophagy associated protein 5 （Atg5）， and p62 in liver tissue were determined by using Western blot. The protein expression levels of autophagy associated protein 1 light chain 3B （LC3B） and ULK1 in liver tissue were determined using immunofluorescence. Real-time fluorescence quantitative PCR （Real-time PCR） was used to measure mRNA expression levels of AMPK， Beclin1， Atg5， ULK1， and p62. ResultCompared with the blank group， the model group exhibited a significant increase in body mass （P<0.01）. Additionally， the levels of FBG， FINS， and HOMA-IR significantly changed （P<0.01）. The structure of liver cells was disordered. The protein expression levels of AMPK， Beclin1， and Atg5 in liver tissue were significantly decreased （P<0.01）， while the expression level of p62 protein was significantly increased （P<0.01）. The expression levels of mRNA and proteins were consistent. Compared with the model group， the body mass of the metformin group and high and medium-dose groups of Rhei Radix et Rhizoma-Coptidis Rhizoma was significantly decreased （P<0.05）. FBG， FINS， and HOMA-IR were significantly decreased （P<0.05，P<0.01）. After treatment， the liver structure damage in each group was alleviated to varying degrees. The protein expressions of AMPK， Beclin1， Atg5， LC3B， and ULK1 were increased （P<0.05，P<0.01）， while the protein expression of p62 was decreased （P<0.01）. The expression levels of mRNA and proteins were generally consistent. ConclusionThe combination of Rhei Radix et Rhizoma-Coptidis Rhizoma can effectively improve liver insulin resistance， regulate the AMPK autophagy signaling pathway， alleviate insulin resistance in db/db mice， and effectively prevent the occurrence and development of type 2 diabetes.

Significant research progress has been made in the development of antibody-drug conjugates (ADCs) for the treatment of ad-vanced breast cancer (ABC),ushering new hope for patients with this refractory disease. Through the conjugation of specific antibodies with highly potent cytotoxic drugs,tumor cells can be precisely targeted and killed while minimizing damage to normal tissues. ADCs such as trastuzumab-emtansine (T-DM1) and trastuzumab deruxtecan (T-DXd),have shown excellent efficacy in the treatment of HER2-positive ABC,significantly prolonging patient survival. Furthermore,ADCs targeting triple-negative breast cancer (TNBC),such as sacituzumab govitecan (SG),have also achieved positive results in clinical trials. With the continuous research,development,and optimization of ADCs,as well as the exploration of combination treatment strategies,ADCs are expected to play an increasingly important role in the treatment of ABC in the future. This article provides an overview of the research progress of ADCs in the treatment of ABC,exploring their efficacy and safety. We aim to offer more treatment options and renewed hope for patients with ABC.

ObjectiveTo explore the mechanism of Dahuang Mudantang in alleviating the intestinal injury in the rat model of acute pancreatitis via the high-mobility group box 1 （HMGB1）/receptor for advanced glycation endproduct （RAGE）/nuclear factor-κB （NF-κB） signaling pathway. MethodOne hundred and twenty SPF-grade Wistar rats received retrograde injection of 5% sodium taurocholate into the biliopancreatic duct for the modeling of intestinal injury in acute pancreatitis. The rats were randomized into blank， model， low-， medium-， and high-dose （3.5， 7， 14 g·kg^-1， administrated by gavage） Dahuang Mudantang， and octreotide （1×10^-5 g·kg^-1， subcutaneous injection） groups （n=20）. The rats in blank and model groups received equal volume of distilled water by gavage. Drugs were administered 1 h before and every 12 h after modeling， and samples were collected 24 h after modeling. The general status of the rats was observed. The biochemical methods were employed to measure the levels of amylase （AMS） and C-reactive protein （CRP） in the serum. The enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and IL-6 in the colon tissue. The morphological changes of pancreatic and colon tissues were observed by hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to measure the expression levels of HMGB1， RAGE， inhibitor of NF-κB kinase （IKK）， and NF-κB suppressor protein α（IκBα）in the colon tissue. ResultThe rats in the model group showed poor general survival， writhing response， reduced frequency of defecation， and dry stool. The symptoms of rats in the model group were mitigated in each treatment group， and the high-dose Dahuang Mudantang showed the most significant effect. Compared with the normal group， the model group had elevated AMS and CRP levels （P<0.05）， which were lowered by Dahuang Mudantang （P<0.05）， especially that at the high dose （P<0.05）. Compared with the normal group， the modeling elevated that levels of TNF-α， IL-1β， and IL-6 （P<0.05）. Such elevations were lowered by Dahuang Mudantang （P<0.05）， and the high-dose group and the octreotide group showed better performance （P<0.05）. The modeling caused necrotic， congested， and destructed pancreatic and colonic tissues， which were ameliorated by the drugs， especially high-dose Dahuang Mudantang. Compared with the normal group， the modeling up-regulated the mRNA levels of HMGB1， RAGE， IKK， IκBα， and NF-κB （P<0.05）. Compared with the model group， Dahuang Mudantang and octreotide down-regulated the mRNA levels of HMGB1， RAGE， IKK， IκBα， and NF-κB （P<0.05）， and the high-dose Dahuang Mudantang demonstrated the best performance （P<0.05）. Western blot results showed a trend consistent with the results of Real-time PCR. ConclusionDahuang Mudantang can improved the general status， reduce inflammation， and alleviate histopathological changes in the pancreatic and colon tissues in the rat model of acute pancreatitis by inhibiting the HMGB1/RAGE/NF-κB signaling pathway.

Multivariate Logistic regression analysis showed that age, occupational status, average income per person in family, number of comorbidities, and attachment anxiety scores were important predictors of patterns of demoralization trajectories in young and middle-aged maintenance hemodialysis patients. Conclusions:This study identified three distinct demoralization trajectories in young and middle-aged maintenance hemodialysis patients, clinical nursing should formulate individualized intervention strategies according to the types of patients′ delirium trajectories.

Objective:To explore the feasibility of functional reconstruction of muscle power in treatment of traumatic muscle defects by transferring part of superficial vastus of lateral thigh.Methods:From March 2020 to March 2023, reconstruction of muscle power with transfer of superficial lateral thigh muscle was performed on 9 patients in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Nine patients were assigned in a study group. A total of 48 patients who previously had the surgery of chimerically grafted superficial vastus of lateral thigh were recruited as the "previous surgery group" and another group of 71 staff volunteers from our hospital were recruited as the "healthy control group". Of the study group, 5 patients had Gustilo type ⅢB injury in forearm (two with defects of flexor muscle group and 3 with extensor muscle group, 2 with the defects in the left and 3 in the right), one had defect of both flexor and extensor muscle groups in dorsal hand, one had defect of right 1st metacarpal with defects of soft tissue and thenar muscle, one had a completely severed right upper arm with a withdrawn musculocutaneous nerve from the biceps brachii and one had Gustilo ⅢC injury in right calf with defects of tibialis anterior, extensor longus and extensor phalangeal muscle. In the emergency surgery, part of the superficial muscles of lateral thigh were taken to reconstruct the muscular power for the defected traumatic muscles. During the surgery, the excessed nerve with a length of 3.0 cm proximally was removed at 3.0 cm from the point where the nerve entered the muscle. In the transfer of superficial chimeric muscle of lateral thigh, a 3.0 cm of sample nerve tissue was taken for HE staining to find out the number of nerve fibers. Musculoskeletal ultrasonography, electromyography and muscle strength test were performed in the postoperative follow-up for observations and evaluations of the effects of surgery. Average length and thickness of muscle were taken from the 48 patients in the "previous surgery group". The measurement was compared with the length of muscle fibers and the number of nerve fibers in the gracilis muscle of the 9 patients in study group. The cross-sectional areas (SCA) at contraction state (C) and resting state (R) of the superficial vastus of lateral thigh were taken from the 71 volunteers in the healthy control group, and the C/R ratio was calculated (CR value). All the 9 patients were included in the postoperative follow up by outpatient visits and via telephone or internet reviews to observe the recovery of muscle strength of the reconstruction of muscle dynamics.Results:In the study group, the number of nerve fibers shown by immunohistochemical HE staining was 1 088±213, with the CR value of graft muscle measured by musculoskeletal ultrasonography at 1.44±0.17. The wound healed smoothly without complication. The average time of postoperative follow-up for the 9 patients was 22.6 (10-38) months. Recovery of muscle strength was found at M5 in 6 patients and M4 in 3 patients. The appearance of the joints was normal. In the previous surgery group, the average muscle thickness of the superficial vastus lateralis muscle was 1.74 cm±0.35 cm and the length of muscle fiber was 8.86 cm±1.59 cm. In the healthy control group, the CR value of the superficial muscle vastus of lateral thigh was found at 1.17±0.12.Conclusion:Reconstruction of muscular power with partial muscle transfer of the superficial vastus of lateral thigh is proposed in this study.

ObjectiveTo reveal the intervention effect of Dahuang Mudantang on pancreatic injury in rats with acute pancreatitis （AP） of dampness-heat in large intestine syndrome and explore its possible mechanism based on network pharmacology. MethodNinety-six SPF-grade Wistar rats were randomly divided into the following six groups： a blank group， a model group， low-， medium-， and high-dose Dahuang Mudantang groups （3.5， 7， and 14 g·kg^-1）， and a Qingyi Lidan granules group （3 g·kg^-1）， with 16 rats in each group. The AP model of dampness-heat in large intestine syndrome was induced in rats except for those in the blank group by "high-temperature and high-humidity environment + high-sugar and high-fat diet + retrograde injection of 5% sodium taurocholate into the pancreaticobiliary duct". The blank and model groups received equal volumes of distilled water by gavage， while the treatment groups were administered Dahuang Mudantang or Qingyi Lidan granules 1 hour before modeling， and 12 and 24 hours after modeling. Samples were collected 1 hour after the last administration. The general conditions of the rats were observed. The AP model of dampness-heat in large intestine syndrome was evaluated. Serum amylase （AMS） and C-reactive protein （CRP） levels were determined using biochemical methods. Pancreatic tissue morphology was observed using hematoxylin-eosin （HE） staining. Network pharmacology was employed to predict potential targets of Dahuang Mudantang in the intervention in AP， and molecular biology technique was used to verify relevant targets. ResultCompared with the blank group， the model group exhibited lethargy， unkempt fur， loose and foul-smelling stools， elevated anal temperature with arching and twisting reactions， significantly increased serum levels of AMS and CRP （P<0.05）， abnormal pancreatic ductules， disordered interlobular spaces， and inflammatory cell infiltration in histopathological examination， as well as pathological changes including pancreatic acinar cell swelling， congestion， and necrosis. Compared with the model group， the treatment groups showed varying degrees of improvement in general survival conditions， reduced twisting reactions， visibly improved stool characteristics， reduced pancreatic tissue edema and necrosis， decreased serum AMS and CRP levels （P<0.05）， with the high-dose Dahuang Mudantang group showing the most pronounced effects （P<0.05）. Network pharmacology prediction indicated that hederagenin， β-sitosterol， and quercetin were the most widely connected active compounds with disease targets. Protein-protein interaction （PPI） network analysis revealed that protein kinase B （Akt）， tumor protein P53 （TP53）， tumor necrosis factor （TNF）， interleukin-6 （IL-6）， transcription factor （JUN）， vascular endothelial growth factor α （VEGFα）， interleukin-1β （IL-1β）， and vascular cell adhesion molecule-1 （VCAM1） were key targets in the "drug-disease" interaction. KEGG enrichment analysis suggested that the response of the mitogen activated protein kinase （MAPK） signaling pathway might be a core mechanism for DHMDT in the intervention in AP. Molecular biology analysis showed that compared with the blank group， the model group had significantly increased levels of TNF-α， IL-6， and VCAM-1 in pancreatic tissue （P<0.05）， as well as significantly elevated expression levels of p38 mitogen-activated protein kinase （p38 MAPK）， mitogen-activated protein kinase-activated protein kinase 2 （MK2）， and human antigen R （HUR） genes and proteins （P<0.05）. Compared with the model group， the treatment groups exhibited decreased levels of TNF-α， IL-6， and VCAM-1 in pancreatic tissue （P<0.05）， reduced expression levels of p38 MAPK， MK2， and HUR genes and proteins， with the high-dose Dahuang Mudantang group showing the most pronounced effects （P<0.05）. ConclusionDahuang Mudantang activates and regulates the p38 MAPK/MK2/HUR signaling pathway to suppress the release of inflammatory factors， thereby improving pancreatic injury.
