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 dosimetric characteristics of intensity modulated proton therapy (IMPT) and photon volumetric modulated arc therapy (VMAT) in typical head and neck malignant tumors.Methods:Three types of typical head and neck tumors (nasopharyngeal carcinoma, parotid gland carcinoma, laryngeal carcinoma) treated at Shandong Cancer Hospital and Institute from December 2023 to December 2024 were taken as research subjects. IMPT and VMAT radiotherapy plans were created according to clinical prescription requirements of target and organs at risk limits respectively. The conformity index (CI), homogeneity index (HI) and gradient index (GI) for target coverage of two radiotherapy plans were evaluated for 3 patients, as well as the dosimetric indicators of organs at risk.Results:The CI of IMPT for nasopharyngeal carcinoma, parotid gland carcinoma and laryngeal carcinoma were 0.70, 0.72 and 0.67, respectively. The HI were 0.11, 0.08 and 0.08, respectively. The GI were 3.08, 2.49 and 3.75, respectively. The CI of VMAT plans were 0.77, 0.82 and 0.91, respectively. The HI were 0.12, 0.10 and 0.04, respectively. The GI were 3.67, 2.63 and 3.45, respectively. The results showed that CI of IMPT plan was slightly lower than that of VMAT plan, and HI of IMPT plan was comparable to that of VMAT plan, the GI of the IMPT plan for patients with nasopharyngeal carcinoma and parotid gland carcinoma was lower than that of the VMAT plan, and the GI of the IMPT plan for patient with laryngeal carcinoma was higher than that of the VMAT plan, and all were within the clinically acceptable range. The IMPT plan has demonstrated significant dose advantages in the treatment of nasopharyngeal carcinoma, parotid gland carcinoma and laryngeal carcinoma. For patient with nasopharyngeal carcinoma, the IMPT plan reduced the D max of the left and right crystals by 54.1% and 50.4%, respectively, compared to VMAT plan, and reduced the D mean of the oral and laryngeal tissues by 40.5% and 49.6%, respectively. For patient with parotid gland carcinoma, IMPT plan reduced the D max of the brainstem and spinal cord by 66.2% and 40.5%, respectively, compared to VMAT plan. For patient with laryngeal carcinoma, IMPT reduced spinal cord D max by 77.0%, while thyroid cartilage D mean increased by 8.0% compared to VMAT plan. For the additional dose in the patients' body, taking the absolute volumes occupied by the prescribed dose areas of 10%, 30%, and 50% in the patients' body as examples, IMPT plan of nasopharyngeal carcinoma patient decreased by 29.7%, 29.6%, and 34.9% compared to VMAT plan, respectively. IMPT plan of parotid gland carcinoma patient decreased by 61.0%, 39.7%, and 17.4% compared to VMAT plan, respectively. IMPT plan of laryngeal carcinoma patient decreased by 63.9%, 31.7%, and 4.1% compared to VMAT plan, respectively. Conclusions:Compared with VMAT plan, IMPT plan can effectively reduce the irradiation dose of most organs at risk near the target of head and neck tumors, but the dose of string organs close to the target area may be higher, which needs attention.

Objective:To evaluate the clinical efficacy and impact on quality of life of the biofeedback (BF) therapy combined with the Wenyang Yiqi Prescription and self-efficacy interventions in patients with functional defecation disorders (FDD).Methods:A prospective, randomized controlled trial design was employed. A total of 128 FDD patients were selected from the Pelvic Floor Center of the Department of Proctology, Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine, between January 2021 and April 2023. These patients were randomly divided into two groups, with 64 cases in each group. Additionally, 41 historical control patients, who had received conventional BF training between June 2015 and January 2018 at the same center, were included for comparison. The historical control group received conventional BF therapy, the intervention group 1 combined BF therapy with self-efficacy interventions, and the intervention group 2 added the Wenyang Yiqi Prescription based on intervention group 1's treatment. All three groups underwent two treatment courses. Constipation symptom scores before and after treatment were performed; self-efficacy was assessed via the Self-Rated Abilities for Health Practices scale (SRAHP); health behaviors were evaluated using the Health-Promoting Lifestyle Profile (HPLP); anxiety and depression were evaluated through Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS); quality of life was measured through SF-36. Clinical efficacy was evaluated based on constipation symptom scores.Results:During the treatment period, seven patients dropped out due to personal reasons, leaving 61 patients in intervention group 1 and 60 patients in intervention group 2 for efficacy analysis.　The total effective rates were 80.32% (49/61) in intervention group 1, 83.33% (50/60) in intervention group 2, and 56.10% (23/41) in the historical control group. The total effective rates of both intervention groups were significantly higher than those in the historical control group ( χ2=7.06, 9.15; P=0.029, 0.010, respectively). After treatment, intervention group 2 showed significantly lower constipation-related straining scores [1 (1, 2) vs. 2 (1, 2), Z=-4.51] compared to intervention group 1 ( P<0.05). Additionally, intervention group 2 had lower scores for straining [1 (1, 2) vs. 2 (1, 2), Z=-3.15] and defecation time [1 (0, 1) vs. 1 (1, 2), Z=-3.13] compared to the historical control group ( P<0.05). Psychological comfort efficacy (19.13 ± 2.51 vs. 16.98 ± 1.86, t=5.36), health responsibility efficacy (23.63 ± 4.69 vs. 22.59 ± 3.05, t=2.06), and overall SRAHP scores (75.98 ± 4.44 vs. 72.33 ± 5.16, t=4.17) were higher in intervention group 2 compared to intervention group 1 ( P<0.05). The HPLP scores (79.33 ± 11.13 vs. 72.80 ± 9.20, t=3.10) of intervention group 2 were higher than those of the historical control group ( P<0.05). Emotional functioning scores (75.98 ± 18.45 vs. 68.92 ± 20.58 and 68.55 ± 18.21, F=20.91) in intervention group 2 were higher than in both intervention group 1 and the historical control group ( P<0.05). Conclusion:The combination of the Wenyang Yiqi Prescription with BF therapy and self-efficacy interventions effectively improves the clinical symptoms and quality of life in FDD patients.

By analyzing the understandings of water points (acupoints connected with the kidney) and its association with water (kidney), zangfu organs and meridian-collateral recorded in Suwen: Shuire Xue Lun (Discussion on Water and Heat Diseases in Plain Question), it is found that the recognition on the water points is different from that on water diseases in Huangdi Neijing (the Yellow Emperor 's Inner Classic). The recognition on the water points focuses on the core theory, "rooted at the kidney", to explain the water diseases. Besides, in association with the study on the connotation of "luo" in Huangdi Neijing, it is discovered that "yinluo" discussed in water points is actually the misunderstanding of "zang zhi yinluo" that means "the connection by the kidney". It is shown that the discussion of water points refer to the elaboration of zangfu organs and 57 acupoints connected with water (the kidney), rather than the theory of collaterals. The characteristics of these 57 acupoints involved and the related needling techniques provide a new approach to the treatment of zangfu diseases.

The diseases and pathological manifestations associated with chongmai (thoroughfare vessel) are the representative in the practical applications of chongmai theory. Elucidating this theory serves as a prerequisite of acupuncture and moxibustion therapy. Based on literature analysis, the diseases and clinical manifestations of chongmai recorded in the time of Huangdi Neijing (The Yellow Emperor's Inner Classic) were analyzed so as to reinterpret the diagnostic process, pathological characteristics, and clinical manifestations of disorders, and evaluate the value of chongmai theory. Chongmai diseases were identified from the palpation initially, known as the "palpation on abdominal pulse". The "qi reversion" of chongmai represents a typical clinical manifestation of chongmai diseases, such as ji (abdominal mass), jia (abdominal hematoma), and shan (hernia), occurring in different sites of the abdomen and in different pathological stages. A part of distribution of chongmai is considered in clinical manifestation, diagnosis and treatment of acupuncture and moxibustion. To emphasize the significance of chongmai in modern acupuncture-moxibustion theory and practice, the diagnostic and therapeutic patterns of the related disorders should be considered in clinical practice. The characteristics of chongmai are reflected in three aspects: qi, blood and abdomen, which are determined by both its inherent properties and the clinical manifestations of related diseases.

Objective To explore the clinical efficacy of edaravone dexborneol combined with intravenous thrombolysis with alteplase,in the treatment of patients with acute ischemic stroke(AIS).Methods The patients with AIS undergoing intravenous thrombolysis with alteplase between January 7,2021 and December 31,2022 were enrolled and randomly divided into observation group and control group.The control group was treated with standard treatment according to the AIS guidelines,and the observation group was treated with edaravone dexborneol injection within 48 hours from thrombolysis to the onset of the disease on the basis of the treatment in the control group.7-day post-thrombolysis National Institutes of Health stroke scale(NIHSS),discharged NIHSS,difference between 7-day post-thrombolysis NIHSS and pre-thrombolysis NIHSS,and 3-month all-cause mortality and 3-month poor prognosis ratio were compared between the two groups.Results A total of 232 patients with AIS were randomly allocated to the observation group(n=1 16)and the control group(n=1 16).The differences between the two groups were not statistically significant for 7-day post-thrombolysis NIHSS and difference between 7-day post-thrombolysis NIHSS and pre-thrombolysis NIHSS(P＞0.05),and there were statistical differences in distribution of the discharged NIHSS score between the observation group and control group[2.0(0,3.0)vs.2.0(1.0,5.0),P＜0.05].The 3-month poor prognosis ratio was significantly lower in the observation group than in the control group(12.1％vs.28.4％;OR=0.252,95％CI 0.105 to 0.602,P=0.002).Conclusion Edaravone dexborneol enhances the efficacy of AIS undergoing intravenous thrombolysis with alteplase and improves the 3-month outcome of patients.

OBJECTIVE: To summarize the research progress of anterior cutaneous nerve injury and repair in knee arthroplasty. METHODS: The relevant literature at home and abroad in recent years was reviewed and summarized from the anatomy of anterior cutaneous nerve, nerve injury grade, clinical manifestations, prevention and treatment of anterior cutaneous nerve. RESULTS: The anterior cutaneous nerve injury is a common complication of knee arthroplasty. Because the anterior cutaneous nerve branches are many and thin, and mainly run between the first and second layers of fascia, this level is often ignored during surgical exposure. In addition, the knee arthroplasty does not routinely perform the exploration and repair of the cutaneous nerve. So the anterior cutaneous nerve injury is difficult to avoid, and can lead to postoperative skin numbness and knee pain. At present, studies have explored the feasibility of preventing its occurrence from the aspects of improved incision and intraoperative separation of protective nerve. There is no effective prevention and treatment measures for this complication. For patients with skin numbness after knee arthroplasty, the effectiveness of drug treatment is not clear. Local nerve block or nerve excision can be used to treat patients with painful symptoms after knee arthroplasty considering cutaneous pseudoneuroma. CONCLUSION Knee arthroplasty is widely used and anterior cutaneous nerve injury is common in clinic. In the future, more high-quality clinical studies are needed to further explore the prevention and treatment measures of this complication and evaluate the clinical benefits obtained.

OBJECTIVE: To investigate the repair method of type Ⅱc injury in the lateral meniscus popliteal tendon area based on the porcine knee joint. METHODS: Eighteen commercially available fresh porcine knee joints were randomly divided into 3 groups ( n=6). After preparing a type Ⅱc injury in the lateral meniscus popliteal tendon area, and the anterior (group A), posterior (group B), or anterior and posterior (group C) of the popliteal hiatus (PH) was sutured by vertical mattress. The tension meter was used to apply gradient tensions of 2, 4, 6, 8, and 10 N along the tibial plateau horizontally, respectively, to pull the midpoint of the lateral meniscus popliteal tendon area. The displacement values before modeling, after modeling, and after suture were recorded. The reduction value of lateral meniscus displacement and reduction rate after suture were calculated and compared between groups. RESULTS: There was no significant difference between groups ( P>0.05) in the displacement values before modeling, after modeling, and after suture under different tensions. There was no significant difference between groups A and C ( P>0.05) in the reduction value of lateral meniscus displacement and reduction rate after suture under different tensions. The reduction value of lateral meniscus displacement and reduction rate after suture in group B were lower than those in groups A and C. The reduction value of lateral meniscus displacement under tension of 2 N and the reduction rates under tensions of 2, 4, and 6 N between groups A and B showed significant differences ( P<0.05). The reduction value of lateral meniscus displacement and the reduction rate under tensions of 2, 4, and 6 N between groups B and C showed significant differences ( P<0.05). CONCLUSION Suturing the anterior area of PH is the key to repairing type Ⅱc injury of lateral meniscus popliteal tendon area.

Objective:To investigate the role of serum CX3CR1 in the diagnosis of coronary artery stenosis and in the evaluation of prognosis after percutaneous coronary intervention.Methods:A total of 101 patients with coronary artery stenosis (≥ 50% stenosis) confirmed with coronary angiography (CAG) in Haiyang People's Hospital from January 2018 to May 2019 who were followed up till May 2021 were included in the observation group. Thirty-four healthy individuals who underwent physical examination during the same period were included in the control group. Patients in the observation group were divided into an in-stent restenosis group (ISR group, n = 28) and a non-ISR group ( n = 73). The expression of CX3CR1 was detected. The incidence of adverse cardiac events was calculated. The sensitivity, specificity, and area under the curve (AUC) plotted for the use of CX3CR1 to diagnose coronary artery stenosis and predict adverse cardiac events were evaluated. Results:The expression of CX3CR1 in the observation group was (3.95 ± 1.05) μg/L, which was significantly higher than (2.30 ± 0.65) μg/L in the control group ( t = 2.87, P < 0.05). The receiver operating characteristic curve analysis showed that the AUC, sensitivity, and specificity of the use of CX3CR1 in diagnosing coronary artery stenosis were 0.892, 75.2%, and 88.2%. The incidence of non-fatal myocardial infarction, angina pectoris, heart failure, and cardiac death in the ISR group was significantly higher compared with the non-ISR group ( χ2 = 8.06, 7.17, 8.06, 7.17, all P < 0.05). The receiver operating characteristic curve analysis results showed that the AUC value of CX3CR1 in predicting non-fatal myocardial infarction, angina pectoris, heart failure, and cardiac death were 0.786, 0.895, 0.997, and 0.887, respectively. Conclusion:CX3CR1 is highly expressed in coronary artery stenosis, which can provide a reference for the diagnosis and prognostic evaluation of coronary artery stenosis.
