Objective: To evaluate the effects of dietary intervention on blood pressure and renal function in patients with hypertensive nephropathy, so as to provide dietary and nutritional guidances for this population. Methods: Hypertensive nephropathy patients who were treated at Zhucheng People's Hospital from March 2023 to February 2024 were selected as the study subjects and randomly divided into the intervention group and the control group. The control group received routine antihypertensive treatment and health lifestyle guidance. On the basis of the treatment and guidance received by the control group, the intervention group implemented dietary intervention in accordance with the Clinical Practice Guidelines for Nutritional Therapy of Chronic Kidney Disease in China (2021 edition) for a period of 3 months. Systolic blood pressure (SBP), diastolic blood pressure (DBP) were measured before and after the intervention, and serum creatinine (Scr), blood urea nitrogen (BUN), uric acid (UA), cystatin and β2-microglobulin were detected. Differences of indicators before and after intervention between the two groups were compared using generalized estimation equation. Results: A total of 83 patients with hypertensive nephropathy were followed up, including 43 cases in the intervention group and 40 cases in the control group. There were no statistically significant differences in gender, age, body mass index, duration of hypertension, family history of hypertension, hypertension grade, physical activity index, or smoking status between the two groups (all P>0.05). The differences in SBP, DBP, Scr, BUN, and UA between the two groups, as well as the differences before and after the intervention, were statistically significant, and there was an interaction between the groups and the intervention time (all P<0.05). After intervention, the levels of SBP, DBP, Scr, BUN, and UA in the intervention group were lower than those in the control group (all P<0.05). The differences in cystatin and β2-microglobulin between the two groups and before and after the intervention were not statistically significant, and there was no interaction between the groups and the intervention time (all P>0.05). Conclusion Dietary intervention has a certain effect on reducing blood pressure and improving renal function indicators in patients with hypertensive nephropathy.

Mental disorders are characterized by disturbances in behavior,volition,emotion,and cognition and are considered emotional diseases in traditional Chinese medicine.Acupuncture is one of the most widely used complementary alternative therapies for the treatment of mental disorders.Recently,there has been growing interest in the use of the Tong Du Tiao Shen(Dredging Du meridian to regulate the spirit)as a primary treatment.However,a comprehensive summary of the establishment and related acupuncture methods of Tong Du Tiao Shen is lacking.This paper aims to address this gap by exploring the origin and development of Tong Du Tiao Shen,its application in treating mental disorders,and the modern biological mechanisms involved.Ultimately,this paper seeks to expand the clinical application of Tong Du Tiao Shen acupuncture and provide a scientific basis for future research in this field.

A lightweight residual attention enhanced Unet(LRAE-Unet)is designed for the fully automatic brain tumor segmentation.LRAE-Unet uses lightweight residual module to solve the problems of gradient disappearance and network degradation when the network layers increases,lightweight self-attention module to suppress the irrelevant areas and highlight the significant features of specific local areas,and enhanced average pooling module with a larger field of perception to reduce the space of feature map,save computing resources and avoid over-fitting.The experiment on BraTS 2019 dataset shows that the proposed method has a Dice similarity coefficient of 91.24%,88.64%and 88.32%in the segmentations of the whole tumor,tumor core and enhanced tumor,which proves its feasibility and effectiveness for brain tumor segmentation.

The lumbosacral transitional vertebra (LSTV) is a common lumbar vertebral variation characterized by unilateral or bilateral enlarged transverse processes. When the enlargement of the transverse processes alters the local biomechanics of LSTV, it may give rise to a series of clinical symptoms known as Bertolotti syndrome. The main manifestations include pain in the lumbosacral region, buttocks, outer side of the lower limbs, numbness, and symptoms related to the sciatic nerve. LSTV is often classified using the Castellvi classification. The presence of lumbosacralization and sacralization of vertebrae in LSTV makes it challenging to accurately locate and number LSTV. So various anatomical landmarks and spinal parameters have been proposed to assist in the localization and numbering of LSTV, but they all have a certain error rate. Even after the lumbar vertebrae is clearly numbered, there is often controversy over the baseline selection for preoperative spinal parameters. Currently, the horizontal level of S 1 is considered the optimal measurement baseline, but this conclusion needs further confirmation in a clinical context. The main basis for LSTV diagnosis is imaging signs, while the diagnosis of Bertolotti syndrome requires local injection of local anesthetics or corticosteroids into the pseudo-joint and the exclusion of other degenerative diseases of the lumbar spine. The treatment of Bertolotti syndrome includes conservative and surgical approaches. Common surgical procedures include fusion and decompression, both of which can achieve good short-term outcomes. However, due to the limited number of patients studied or a lack of direct comparisons, it is challenging to determine the superiority of these two methods in terms of medium to long-term effectiveness. This article provides a comprehensive review of the symptoms and causes of Bertolotti syndrome, preoperative localization and numbering of LSTV, baseline selection for preoperative spinal parameter measurements, and treatment methods.

The clinical practice guidelines of traditional Chinese medicine （TCM） have problems such as limited clinical application and unclear implementation effects， which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice， this article proposes a model of combining TCM guidelines with real-world study， which includes 4 steps. Firstly， during the implementation process of the guidelines， a high-quality research database is established. Secondly， the recommendations in the guidelines are evaluated based on the established database in multiple dimensions， including applicability， effectiveness， safety， and cost-effectiveness， and thus their effectiveness in practical applications can be determined. Thirdly， based on the established database， core prescriptions are identified， and the targeted populations and medication plans are determined. That is， the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies， dosages， and duration on efficacy. Fourthly， the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions， improving their application in clinical practice. Moreover， this model can reduce research costs and improve research efficiency. When applying this model， researchers need to pay attention to the quality of real-world evidence， ensuring that it can truly reflect the situation in clinical practice. In addition， importance should be attached to the clinical application of guideline recommendations， ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally， full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion， the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.

The classification of traditional Chinese medicine （TCM） syndromes is one of the core technical elements in the industry standard of Specification of Diagnosis and Therapeutic Effect Evaluation of Diseases and Syndromes in TCM. In the past，when clinical standards for TCM were formulated，the determination of TCM syndrome classification relied heavily on textbooks and expert experience，lacking systematic research. This approach thus failed to reflect the advancement and scientificity of the standards，thereby affecting their implementation and application. This article reviewed the presentation forms and technical methods of TCM syndrome classification，including the two-tier syndrome classification model with primary and secondary symptoms，as well as the application of modern literature research，ancient literature research，Delphi method，in-depth expert interviews，consensus conferences，and real-world research. When syndrome classification standards are developed，it is necessary to build upon modern literature research，adopt a mixed approach combining qualitative research and quantitative analysis results，and reach expert consensus through consensus conferences. Through systematic research，the scientificity，applicability，and coordination of TCM syndrome classification standards can be enhanced，providing guidance for the standardization of TCM.

Due to the non-targeted release and low solubility of anti-gastric cancer agent,apatinib(Apa),a first-line drug with long-term usage in a high dosage often induces multi-drug resistance and causes serious side effects.In order to avoid these drawbacks,lipid-film-coated Prussian blue nanoparticles(PB NPs)with hyaluronan(HA)modification was used for Apa loading to improve its solubility and targeting ability.Furthermore,anti-tumor compound of gamabufotalin(CS-6)was selected as a partner of Apa with reducing dosage for combinational gastric therapy.Thus,HA-Apa-Lip@PB-CS-6 NPs were constructed to synchro-nously transport the two drugs into tumor tissue.In vitro assay indicated that HA-Apa-Lip@PB-CS-6 NPs can synergistically inhibit proliferation and invasion/metastasis of BGC-823 cells via downregulating vascular endothelial growth factor receptor(VEGFR)and matrix metalloproteinase-9(MMP-9).In vivo assay demonstrated strongest anti-tumor growth and liver metastasis of HA-Apa-Lip@PB-CS-6 NPs adminis-tration in BGC-823 cells-bearing mice compared with other groups due to the excellent penetration in tumor tissues and outstanding synergistic effects.In summary,we have successfully developed a new nanocomplexes for synchronous Apa/CS-6 delivery and synergistic gastric cancer(GC)therapy.

Objective:To compare the clinical efficacy of arthroscopic partial and complete repair for massive rotator cuff tears.Methods:A total of 32 patients who underwent arthroscopic partial repair of massive rotator cuff tears in the Department of Sports Medicine, Peking University Third Hospital from March 2016 to December 2019 were retrospectively analyzed, including 15 males and 17 females, aged 62±6.8 years (range, 51-77 years), with 5 cases on the left side and 27 cases on the right side. Cause of injury: 4 cases were injured by car accident, 8 were injured by fall, and 20 had no obvious cause. 32 patients who underwent arthroscopic complete repair of massive rotator cuff tears during the same period were included according to a sample size of 1∶1 matched based on age, sex, tear size and fat infiltration index. Clinical outcomes were evaluated using the visual analogue scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, Simple Shoulder Test (SST) score, and range of motion. Fatty infiltration and cuff healing were assessed using the Goutallier and Sugaya classifications on MRI, respectively.Results:All patients successfully completed the surgery and were followed up for 46.1±11.3 months (range, 36-72 months). Preoperative and final follow-up VAS scores were 6.6±1.8 and 1.6±1.1 in the complete repair group, and 6.4±1.9 and 1.4±1.3 in the partial repair group. Both groups showed significant postoperative improvement ( P<0.05), with no significant difference between groups at the final follow-up ( t=-0.729, P=0.468). The ASES score, UCLA shoulder score, and SST at the final follow-up were 81.7±6.5, 28.6±2.9, and 9.8±2.5, respectively, in the complete repair group, and 82.4±7.3, 28.1±2.6, and 9.1±1.9 in the partial repair group, and the difference between the groups was not statistically significant ( P>0.05). In the complete repair group, one case underwent reverse shoulder replacement for rotator cuff re-tear two years after surgery, and one case developed pseudoparalysis for rotator cuff re-tear 8 months after surgery but had no significant pain and did not receive further treatment; in the partial repair group, two cases underwent tendon transposition surgery for shoulder pain. Conclusion:Arthroscopic partial repair improves shoulder function and reduces pain in patients with massive rotator cuff tears, with similar efficacy to complete repair and has high surgical safety.

Objective:To investigate the efficacy and safety of retroperitoneal soft tissue sarcoma resection combined with nephrectomy.Methods:The clinical data of 27 cases undergoing retroperitoneal soft tissue sarcoma resection combined with nephrectomy at the Gastrointestinal Tumor Center , Guangdong Provincial Hospital , Traditional Chinese Medicine from Jun 2017 to Aug 2022 were retrospectively analyzed for the indication of nephrectomy, postoperative progression of renal insufficiency and survival rate.Results:Twenty-six cases (96%) achieved R 0/R 1 resection and 1 case nderwent R 2 resection. Six cases underwent combined unilateral nephrectomy and 21 patients underwent combined multi-organ resection with a median number of resections of 4 (2,5). Postoperative pathology suggested that the combined resected kidney was positive for tumor infiltration in 17 cases. Five cases had Clavien-Dindo grade 3 or higher complications and no deaths occurred within 30 days after surgery. At the 90th day after surgery, 19 cases (70%) had decreased renal function ( Z=2.88, P=0.04), with a median decrease of -3.96 (-30.36, 0.31)ml·(min·1.73 m 2) -1, including 8 cases of preoperative Chronic Kidney Disease(CKD)1 stage progression (6 cases of CKD 2 stage, 2 cases of CKD 3 stage); 2 cases of CKD 2 stage progressed to CKD 3 stage; 1 case of preoperative CKD 3 stage progressed to CKD 4 stage. During the follow-up period of 3-38 months, no patient progressed to CKD 5 stage and no patient required dialysis treatment. Conclusion:Retroperitoneal soft tissue sarcoma resection combined with nephrectomy is safe and feasible while improving tumor radicality.

Objective:To explore the feasibility and value of performing a three-sided encapsulation procedure based on fascia anatomy in laparoscopic lateral lymph node dissection (LLND) for middle and low rectal cancer.Methods:This was a retrospective review. The study cohort comprised patients who met the diagnostic criteria for rectal cancer according to the Chinese Guidelines for the Diagnosis and Treatment of Colorectal Cancer, had a short lymph node diameter of >5 mm on the lateral side within the 15 days before surgery, were evaluated as feasible candidates for laparoscopic total mesorectal excision+LLND surgery, had been diagnosed with low or intermediate level rectal cancer, and whose tumor was less than 8 cm away from the anal verge according to pathological examination of the operative specimen. Patients with a history of other malignant tumors of the abdomen or with incomplete follow-up data were excluded. Forty-two patients with middle and low rectal cancer who had undergone lateral lymph node dissection in diagnosis and treatment center of Gastrointestinal Cancer of Guangdong Hospital of Chinese Medicine from Jan.2018 to Dec.2022 were enrolled. There were 24 men (57.1%) and 18 women (42.9%) aged 58.4±11.8 years and the median BMI was 22.5 (19.3–24.1) kg/m 2. The main point of the three-sided encapsulation procedure is to expand the external side medial to the external iliac artery and vein, narrowing the range of exterior side dissection. The anterior-medial side is designed to expand the vesical fascia to define the range of anterior-medial side extension. The internal side is fully extended to the ureterohypogastric nerve fascia; the distal point of the caudal extension reaches the level of the Alcock canal and the bottom reaches the piriformis, enabling dissection of the obturator nerve and No.283 lymph nodes. No.263D lymph nodes are dissected by exposing the internal iliac artery and its branches, dissecting the group No.263P lymph nodes, and severing the inferior vesical artery. Finally, the lateral lymphatic tissue is completely resected. Relevant variables were recorded, including the number of lateral lymph nodes detected, the rate of lymph node metastasis, operation duration, intraoperative blood loss, postoperative complications, postoperative hospital stay, and 3-year overall survival rate. Results:Laparoscopic surgery was successfully completed in all patients with no conversions to open surgery and no intraoperative complications. Twenty-seven (64.3%) of the study patients underwent left-sided LLND, 10 (23.8%) right-sided LLND, and five (11.9%) bilateral LLND, with lymph nodes cleared on both sides. All patients' lymph nodes were examined pathologically. A median of 17.0 (11.7, 26.0) lymph nodes was detected, the median of lateral lymph nodes being 5.0 (2.0, 10.2). The median operation time was 254.5 (199.0, 325.2) minutes. The median intra-operative blood loss was 50.0 (30.0, 100.0) mL. All patients were diagnosed with adenocarcinoma by pathological examination of the operative specimen. Two patients developed postoperative intestinal obstruction, one lymphatic leakage, and one a perineal incision infection. There were no cases of anastomotic leakage. The median postoperative hospital stay was 6.0 (5.0, 7.0) days and the median follow-up time 23.5 (9.0, 36.7) months. During follow-up, three patients (7.1%) died of tumor recurrence and metastasis. Two (4.8%) experienced mild urinary dysfunction, and one (2.4%) had moderate postoperative erectile dysfunction. One patient (2.4%) was found to have prostate and lung metastases 3 month after surgery. The 3-year overall survival rate was 74.4%.Conclusions:Three sided encapsulation is a safe and feasible procedure for LLND, achieving accurate and complete clearance of lateral lymphatic tissue.
