OBJECTIVE: To investigate the effectiveness of knee arthroscopy with wire anchor nailing composite double pulley technique in the treatment of anterior cruciate ligament (ACL) tibial avulsion fracture involving the anterior root of the lateral meniscus (LM). METHODS: Clinical data of 35 patients with ACL tibial avulsion fracture involving the anterior root of the LM admitted between January 2019 and September 2023 and met the selection criteria were retrospectively analysed. There were 20 males and 15 females; ages ranged from 10 to 57 years, with a mean of 29 years. The time from injury to surgery ranged from 3 to 20 days, with a mean of 9.6 days. Meyers-McKeever classification included 5 cases of type Ⅱ, 12 cases of type Ⅲ, and 18 cases of type Ⅳ. Preoperative anterior knee instability Lachman test and anterior drawer test were positive. The anterior root of the LM as well as the avulsion fracture block were fixed using suture anchor nails compounded with double pulley technique under arthroscopy. Postoperative X-ray films were performed to assess fracture healing; knee stability was assessed using the anterior drawer test and Lachman test, anterior laxity of the knee was measured by KT-2000, and knee function was assessed using the Lysholm score and the International Knee Documentation Committee (IKDC) score; at last follow-up, the recovery of the meniscus was assessed using the McMurry test and knee hyperextension test. RESULTS: All the patients were successfully operated, the operation time ranged from 56 to 78 minutes,with an average of 67.6 minutes, and there was no nerve or blood vessel injury during operation. Thirty-five cases were followed up 12-18 months with an average of 15.1 months. During the follow-up, there was no infection, knee stiffness, loosening of internal fixation, fracture displacement, or re-fracture. The fractures all healed, with a clinical healing time of 8-15 weeks, averaging 10.9 weeks. At last follow-up, 4 patients had weakly positive anterior drawer test and Lachman test, and the rest were negative; McMurry test and knee hyperextension test were negative; no patient complained of knee extension pain or straightening obstacles, and all the patients resumed their normal life or sports and labour; 16 patients with unclosed epiphyses did not have any epiphyseal injuries or growth disorders. Lysholm score, IKDC score, and KT-2000 anterior knee laxity at last follow-up significantly improved when compared with preoperative ones ( P<0.05). CONCLUSION The treatment of ACL tibial avulsion fracture involving the anterior root of the LM with suture anchor composite double pulley technique can effectively fix the anterior root of the LM while fixing the avulsion fracture block, and better restore the function and stability of the knee joint.

OBJECTIVES: To evaluate the feasibility, efficacy and safety of Sentinel cerebral embolic protection device (CEPD) during transcatheter aortic valve replacement (TAVR). This study is a subgroup analysis of the China Moderate to Severe Valvular Heart Disease Registry, which has been registered at the Chinese Clinical Trial Registry (ChiCTR2300075006). METHODS: Patients undergoing TAVR with the Sentinel CEPD from October 2023 to September 2024 were retrospectively enrolled. A total of 80 patients were included, with a median age of 72 (68, 76) years, including 52 males (65.0%) and 28 females (35.0%); 62 patients (77.5%) with tricuspid valves, and 18 patients (22.5%) with bicuspid valves; 34 patients (42.5%) with type Ⅰ aortic arch, 24 patients (30.0%) with type Ⅱ aortic arch, 12 patients (15.0%) with type Ⅲ aortic arch, and 10 patients (12.5%) with bovine-type aortic arch. Clinical data of the patients were summarized and analyzed. The primary endpoints were success rate of Sentinel CEPD implantation, as well as all-cause death, symptomatic stroke, transient ischemic attack, and Sentinel CEPD access vessel complications during hospitalization and within 30 days postoperatively. RESULTS: In the 80 patients, self-expanding valves were used in 68 cases (85.0%) and balloon-expandable valves in 12 cases (15.0%). Seventy-nine patients (98.8%) successfully underwent TAVR with Sentinel CEPD deployment. Macroscopically visible debris was captured in 92.5% (74/80) by filters of Sentinel CEPD. Although the procedure time for Sentinel CEPD placement was slightly longer in patients with bovine-type aortic arch, there was no statistically significant difference in deployment time among different aortic arch types (P>0.05). During hospitalization and within 30 days postoperatively, only one case of transient ischemic attack occurred, and there was no all-cause mortality, symptomatic stroke, or access-site vascular complications related to the Sentinel CEPD observed. CONCLUSIONS The Sentinel CEPD demonstrates high feasibility across aortic arch types, potential efficacy in embolic capture, and excellent safety in TAVR.

Objective: To investigate the antidepressant effects of Yuanzhi (Polygalae Radix, PR) aqueous extract on chronic unpredictable mild stress (CUMS)-induced depression rat models and the underlying mechanisms. Methods: A total of 40 male Sprague Dawley (SD) rats were randomly divided into control, model, low dose of PR (PR-L, 0.5 g/kg), high dose of PR (PR-H, 1 g/kg), and fluoxetine (10 mg/kg) groups, with 8 rats in each group. Except for the rats in control group, those in the other four groups underwent CUMS-induced depression modeling. PR and fluoxetine were administered intragastrically once daily, 30 min prior to the CUMS procedure, for 14 consecutive days until the behavioral tests were performed. After CUMS modeling, the sucrose preference test (SPT), open field test (OFT), novelty-suppressed feeding test (NSFT), forced swim test (FST), and tail suspension test (TST) were employed to assess the pharmacological effects of PR on the mitigation of depressive-like behaviors in rat models. Additionally, the enzyme-linked immunosorbent assay (ELISA) was utilized to quantify the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the rats. Western blot analysis was also conducted to evaluate the protein expression levels of nuclear factor kappa-B (NF-κB), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nucleotide-binding oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein containing caspase recruitment domain (ASC), and caspase-1 in the hippocampal tissues of the rats. Immunofluorescence staining was performed to observe the morphological changes in ionized calcium-binding adapter molecule 1positive (Iba-1+) cells in the dentate gyrus (DG) of rats with CUMS-induced depression. Result: (i) Treatment with PR-H and fluoxetine resulted in significant enhancements in both the total distance and time the rats moved during tests (P < 0.01 and P < 0.05, respectively). Post-administration of PR-H and fluoxetine also led to statistically significant increase in sucrose preference among rats (P < 0.05). Besides, PR-L, PR-H, and fluoxetine treatment markedly decreased the latency of ingestion (P < 0.05, P < 0.05, and P < 0.01, respectively). As observed from the FST, PR-L, PR-H, and fluoxetine presented antidepressant effects on rats with CUMS-induced depression, leading to the reduction in time of their immobility (P < 0.05, P < 0.01, and P < 0.01, respectively). The results of TST indicated reduced immobility time in rats receiving PR-H and fluoxetine treatment as well (P < 0.01). (ii) Rats in model group showed an increase in the levels of Iba-1+ microglia in their left and right brains in comparison with control group (P < 0.01). However, such increase was negated post PR treatment (P < 0.01). Treatment with PR-L, PR-H, and fluoxetine considerably reduced the levels of inflammatory factors (TNF-α, IL-1β, and IL-6, P < 0.01). In addition, treatment of PR-L and PR-H effectively counteracted the elevated levels of NLRP3, ASC, and caspase-1, and markedly down-regulated the expression levels of phosphorylated p65 (p-p65), COX-2, and iNOS in rats’ hippocampus (P < 0.01). Conclusion Collectively, these findings indicate that PR exerts an antidepressant effect on rats with CUMS-induced depression partially through the modulation of the NLRP3 and NF-κB signaling pathways.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

ObjectiveTo investigate the therapeutic effect of Ganmai Dazao Tang on breast cancer-related depression and explore the mechanism of the decoction in regulating immune inflammation and neurotransmitters via the mitogen-activated protein kinase （MAPK）/nuclear factor-κB （NF-κB） pathway. MethodBALB/c mice were randomized into control， model， fluoxetine （5 mg·kg^-1·d^-1）， and low- and high-dose （crude drug 20 and 40 g·kg^-1， respectively） Ganmai Dazao Tang groups （n=10）. The mouse model of 4T1 orthotopic transplantation-induced breast cancer-related depression-like behavior was established. The depression-like behavior of mice was assessed by the tail suspension test and the forced swimming test. RT-qPCR was employed to determine the mRNA levels of interleukin （IL）-17A， forkhead box P3 （FoxP3），IL-1β， IL-6， and tumor necrosis factor-α （TNF-α） in the cerebral cortex. Flow cytometry was employed to measure the proportions of immune cell subsets in the spleen and thymus. HPLC-MS/MS was employed to measure neurotransmitter levels in the cerebral cortex. Western blotting was employed to detect the activation of the MAPK/NF-κB pathway. ResultCompared with the model group， administration of Ganmai Dazao Tang at a dose of 40 g crude drug·kg^-1 continuously for 4 weeks shortened the immobility time of modeled mice in the tail suspension and forced swimming tests （P<0.05）， down-regulated the mRNA levels of IL-1β， IL-17A， and TNF-α （P<0.05）， increased the proportions of T cells， CD4⁺ T cells， B cells， helper T 17 （Th17） cells， and regulatory T （Treg） cells， and reduced the proportion of CD8⁺ T cells （P<0.05）. Furthermore， it lowered the levels of 5-hydroxyindoleacetic acid （5-HIAA） and kynurenine （Kyn）， decreased the kynurenine/tryptophan （Kyn/Trp） ratio （P<0.05）， increased the content of 5-hydroxytryptamine （5-HT）， and down-regulated the protein levels of phosphorylated extracellular signal-regulated kinase （p-ERK）， phosphorylated p38 MAPK， and phosphorylated nuclear factor-κB p65 （P<0.05）. ConclusionGanmai Dazao Tang can down-regulate the expression of inflammatory cytokines such as IL-1β， IL-17A， and TNF-α， restore 5-HT metabolism and Kyn/Trp balance， increase the 5-HT content， and reduce the activation of p38 MAPK， ERK， and the MAPK-mediated NF-κB signaling pathway to reduce neuroinflammation in the treatment of cancer-related depression.

BACKGROUND:Traumatic patellar dislocation with medial patellofemoral ligament tearing at femoral attachment or body is usually performed by medial patellofemoral ligament reconstruction surgery.To promote tendon bone healing after medial patellofemoral ligament reconstruction,the researchers used a variety of biological treatment technologies including growth factors,stem cells and platelet-rich plasma. OBJECTIVE:To investigate the clinical effect of medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with autologous hamstring tendon for traumatic patellar dislocation. METHODS:Thirty-seven patients with traumatic patellar dislocation in First Hospital of Qinhuangdao from February 2019 to February 2021 were randomly divided into a trial group(n=18)and a control group(n=19).The trial group received medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with an autologous hamstring tendon.The control group received medial patellofemoral ligament reconstruction by a simple autologous hamstring tendon.Patients in the two groups were followed up for 12 months.Knee pain and functional status were evaluated by visual analog scale score,Lysholm score,Kujala patellofemoral joint score and knee range of motion.The patellar tilt angle,patellar congruence angle and patellar lateral shift rate of the patellofemoral joint were measured by MRI and CT films to evaluate the stability and improvement of the patellofemoral joint. RESULTS AND CONCLUSION:(1)The visual analog scale scores of the two groups at 6 and 12 months after operation were lower than those before operation(P<0.05).The Lysholm score and Kujala patellofemoral joint score at 6 and 12 months after operation were higher than those before operation(P<0.05).The Lysholm score and Kujala patellofemoral joint score in the trial group were higher than those in the control group 6 months after operation(P<0.05).There was no significant difference between the two groups in the visual analog scale score,Lysholm score and Kujala patellofemoral joint score 12 months after operation(P>0.05).(2)The patellar tilt angle,patellar congruence angle,patellar lateral shift rate and range of motion of the patellofemoral joint were significantly improved in both groups 12 months after operation(P<0.05).The patellar tilt angle was smaller in the trial group than that in the control group 12 months after operation(P<0.05).Patellar congruence angle,patellar lateral shift rate,range of motion and MRI score were not statistically significant between the two groups 12 months after operation(P>0.05).(3)These results confirm that medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with autologous hamstring tendon can treat traumatic dislocation effectively,improve the function of the knee joint,and restore the movement track of the patella.

Objective:To analyze the epidemiological characteristics and clinical features of pertussis cases reported in Shandong Province of China.Methods:Data on pertussis cases in Shandong Province from 2007 to 2022 were collected from China Information System for Disease Control and Prevention. At the same time, some case information was collected from the database of notifiable pertussis in Shandong Province from 2007 to 2022. The distribution characteristics and clinical features of pertussis were analyzed. A spatial distribution map of pertussis cases in Shandong Province was drawn.Results:A total of 26 122 pertussis cases were reported in Shandong Province during 2007-2022, with an annual incidence rate ranging from 0.11 to 5.77 cases per 100 000 people. Cases occurred throughout the whole year, with a seasonal peak occurring in spring and summer, especially in July and August. In recent years, reported cases were mainly distributed in the central and western regions of Shandong Province, with fewer cases in the eastern region. The hot spots of the disease shifted from Heze and Dezhou City in 2007-2013 to Jinan and Tai′an city in 2014-2022. The age range of onset was from 1 day to 93 years old. The proportion of cases with age≤1 year was the largest (41.81%, 10 922/26 122), and the proportion of cases aged 0-6 months decreased from 32.21% (67/208)-55.67% (157/282) within the period of 2007 to 2013 to 16.78% (883/5 263)-41.97% (444/1 058) within the period of 2014 to 2022, with a statistically significant trend ( χ2 trend=670.01, P<0.001). There were 13 682 male cases and 12 440 female cases, with a male-female ratio of 1.10∶1. The male-female ratio was 1.45∶1 (806∶556) from 2007 to 2013 and 1.08∶1 (12 876∶11 884) from 2014 to 2022. The proportion of women increased from 42.31% (88/208) in 2007 to 47.84% (2 518/5 263) in 2022, and with a significant trend ( χ2 trend=22.25, P<0.001). In pertussis cases, the proportions of scattered children, kindergarten children and students were 71.38% (18 645/26 122), 15.13% (3 951/26 122), and 11.60% (3 031/26 122), respectively.

Among 24 802 cases, there were 15 542 cases (62.66%) with a history of immunization against pertussis vaccine. Conclusion:From 2007 to 2022, the incidence rate of pertussis cases in Shandong Province shows an upward trend, with the majority being young children, and the clinical symptoms are relatively typical.

Objective:To identify the risk factors for prolonged length of stay in post-anesthesia care unit (PACU-LOS) and development of a prediction model in the patients undergoing radical esophagectomy.Methods:The medical records from patients of both sexes, aged 40-80 yr, of American Society of Anesthesiologists Physical Status classificationⅠ-Ⅲ, transferred to PACU with tracheal intubation after radical esophagectomy under general anesthesia in our hospital from January 2019 to December 2020, were retrospectively collected. The patient′s age, gender, American Society of Anesthesiologists Physical Status classification, smoking history, drinking history, history of non-thoracic surgery, history of hypertension, history of diabetes mellitus, preoperative anemia, respiratory diseases, doses of anesthetics, preoperative nerve block, intraoperative consumption of opioids and dexmedetomidine, operation method (thoracotomy and endoscopic surgery), operation time, usage of vascular drugs, bradycardia, hypotension, red blood cell infusion, plasma infusion, total infusion volume, blood loss and urine volume were collected. The extubation time in PACU, visual analog scale scores at rest at 10 min after extubation, consumption of rescue analgesics in PACU, hypoxemia after extubation, and occurrence of nausea and vomiting were also collected. Patients were divided into PACU-LOS normal group (PACU-LOS≤2 h) and PACU-LOS prolonged group (PACU-LOS>2 h) according to the PACU-LOS. Logistic regression analysis was used to identity the risk factors for prolonged PACU-LOS in the patients undergoing radical esophagectomy, and the predictive model was established and verified. The receiver operating characteristic curves were used to evaluate the model discrimination and Hosmer-Lemshow goodness-of-fit test was used to evaluate the consistency of the model.Results:A total of 943 patients were included in this study, and the incidence of prolonged PACU-LOS was 15.7%. The results of logistic regression analysis showed that chronic obstructive pulmonary disease ( OR=4.900, 95% confidence interval [ CI] 2.512-9.556), increasing age ( OR=22.154, 95% CI 6.736-73.003), prolonged time of extubation ( OR=1.214, 95% CI 1.174-1.256) and hypoxemia after extubation ( OR=4.891, 95% CI 2.167-11.039) were risk factors for prolonged PACU-LOS, and the preoperative use of nerve block ( OR=0.358, 95% CI 0.190-0.672) was a protective factor for prolonged PACU-LOS in the patients undergoing radical esophagectomy ( P<0.05). The area under the receiver operating characteristic curve (95% CI) was 0.947 (0.925-0.963), the sensitivity was 0.878, and the specificity was 0.906. The internal validation of the prediction model was carried out using the receiver operating characteristic curve in the validation set, and the area under the curve (95% CI) was 0.942 (0.895-0.942, P<0.001) and the Youden index was 0.784. The line chart prediction model was developed. The prediction analysis model was verified by Hosmer-Lemshow test, P<0.001, and the C-index visualized line chart prediction model was 0.946. Conclusions:Preoperative chronic obstructive pulmonary disease, increasing age, prolonged time of extubation and hypoxemia after extubation are risk factors for prolonged PACU-LOS, and preoperative use of nerve block is a protective factor for prolonged PACU-LOS. The risk prediction model developed can effectively predict the occurrence of prolonged PACU-LOS in the patients undergoing radical esophagectomy.

OBJECTIVE To investigate the effect and mechanism of Panax notoginseng saponins （PNS） on wound healing after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF）/ vascular endothelial growth factor receptor-2 （VEGFR2） signaling pathway. METHODS SD rats were selected to establish a postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model group， PNS low-dose and high-dose groups （15， 30 mg/cm2）， high-dose of PNS+2-methoxyestradiol （2ME2） group （PNS 30 mg/cm2+HIF-1α inhibitor 2ME2 4 mg/kg）， with 10 rats in each group. Another 10 normal rats were selected for back hair removal treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or （and） intraperitoneally， once a day， for 3 weeks. After the last administration， the wound healing rate （excluding the control group）， microvascular density （MVD）， the expression of collagen Ⅰ and fibronectin （FN） in the wound tissue were detected in each group； the levels of angiogenic factors [VEGF， E-mail：842710813@qq.com angiopoietin-Ⅰ （Ang-Ⅰ）， Ang-Ⅱ] in serum， the levels of inflammatory factors [interleukin-6 （IL-6） and IL-2] in serum binggui7183@163.com and wound tissue as well as the expressions of the related proteins of HIF-1α/VEGF/VEGFR2 signaling pathway in the wound tissue of rats were also detected in each group. RESULTS The MVD， the expression of collagen Ⅰ and FN in the wound tissue， and the levels of IL-6 and IL-2 in serum and wound tissue of rats increased significantly in the model group， compared to the control group （P＜0.05）， while the serum levels of VEGF， Ang- Ⅰ and Ang-Ⅱ decreased significantly （P＜0.05）. The wound healing rate， the MVD in wound tissue， the serum levels of VEGF， Ang-Ⅰ and Ang-Ⅱ， the expressions of collagen Ⅰ and FN in the wound tissue， and protein expressions of HIF-1α， VEGF and VEGFR2 in the PNS low-dose and high-dose groups increased significantly， compared to the model group （P＜0.05）， while the levels of IL-6 and IL-2 in serum and wound tissue decreased significantly （P＜0.05）； the high-dose PNS had a stronger effect （P＜ 0.05）. 2ME2 could weaken the effect of PNS on above indicators of rats after anal fistula surgery （P＜0.05）. CONCLUSIONS PNS can promote the production of angiogenic factors and inhibit the production of pro-inflammatory factors， thereby promoting wound healing in rats after anal fistula surgery. The above effects are related to the activation of HIF-1α/VEGF/VEGFR2 signaling pathway.

Objective To compare the effects of ginsenosides Rg1 and Rb1 on depression-and anxiety-like behaviors in chronic unpredictable stress-induced rats.Methods Seventy male SPF grade SD rats were tested for sugar and water preference after 5 days of adaptation and divided into seven groups according to their preference index:a control group,model group,fluoxetine hydrochloride group,ginsenoside Rg1 24 mg/kg group,ginsenoside Rg1 48 mg/kg group,ginsenoside Rb1 33 mg/kg group,and ginsenoside Rb1 67 mg/kg group.All rats,except for the control group,were subjected randomly to one or two different stimulating factors every day for a total of 35 days.On the 36th day,behavioral experiments including sugar and water preference,open field,novel environment feeding inhibition,elevated cross maze,and forced swimming experiments were conducted to investigate the anti-depression and anti-anxiety effects of the treatments.Serum and hippocampal levels of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-α and serum corticosterone were measured by enzyme-linked immunosorbent assay.Results Compared with the model group,ginsenoside Rg1 and Rb1 significantly increased sucrose consumption in the sucrose preference test and decreased immobility in the forced swimming test.Ginsenoside Rg1(48 mg/kg)significantly reduced the latency to eat in the novelty-suppressed feeding test,and ginsenoside Rg1(24 and 48 mg/kg)significantly increased the percentage of open arm entries and time in the elevated cross maze test.Serum corticosterone levels were significantly decreased in the ginsenoside Rg1 and Rb1 groups,serum IL-1β and IL-6 levels were significantly decreased in the ginsenoside Rg1(48 mg/kg)group,serum TNF-α and IL-6 levels were significantly decreased in the ginsenoside Rb1(33 mg/kg)group,and IL-1β,IL-6,and TNF-α levels in the hippocampus were significantly decreased in the ginsenoside Rg1(48 mg/kg)and Rb1(67 mg/kg)groups.Conclusions Both ginsenosides can regulate the hypothalamic-pituitary-adrenal axis and inhibit neuroinflammation,improving depression-and anxiety-like behaviors in rats induced by chronic unpredictable stress.Ginsenoside Rg1 has a significantly better anti-anxiety effect than Rb1.
