Retinal microcirculatory disorder is a key factor in the occurrence and development of diabetic retinopathy （DR）， and also an important link in the prevention and treatment of DR. The theory of "Gaozhuo" holds that the microcirculatory disorder in DR is based on the deficiency of spleen Qi and is characterized by the obstruction caused by "Gaozhuo" and blood stasis. The deficiency of spleen Qi is an essential precondition for the endogenous formation and accumulation of Gaozhuo， while Gaozhuo invasion is the direct cause of microcirculatory disorders in DR. The deficiency of spleen Qi and the endogenous formation of Gaozhuo mean the process in which glucose metabolism dysfunction induces an excessive production of inflammatory factors and lipid metabolites. The obstruction caused by "Gaozhuo" and blood stasis is the direct pathogenesis of microcirculatory disorders in DR， encompassing two stages： Gaozhuo obstruction and turbidity and stasis stagnation. Gaozhuo obstruction and turbidity and stasis stagnation represent the process in which inflammatory factors and lipid metabolites damage the retinal microcirculation and induce thrombosis， thus mediating microcirculatory disorders. Turbidity and stasis stagnation and blood extravasation outside the vessels reveal the progression to microvascular rupture and hemorrhage resulting from the microcirculatory disorders. According to the pathogenesis evolution of the theory of "Gaozhuo"， microcirculatory disorders in DR can be divided into deficiency of spleen Qi with Gaozhuo obstruction， deficiency of spleen Qi with turbidity and stasis stagnation， and turbidity and stasis stagnation with blood extravasation outside the vessels. Clinically， treatment principles should focus on strengthening the spleen and benefiting Qi， resolving turbidity， and dispersing stasis. Different syndrome patterns should be addressed with tailored therapies， such as enhancing the spleen and benefiting Qi while regulating Qi and reducing turbidity， strengthening the spleen and benefiting Qi while resolving turbidity and dispelling stasis， and strengthening the spleen and resolving turbidity while removing stasis and stopping bleeding.

ObjectiveTo explore the effect of elbow-wrist functional orthosis on plantar pressure distribution and balance function in stroke patients with hemiplegia. MethodsFrom June, 2024 to April, 2025, 60 patients with post-stroke hemiplegia were recruited from Huashan Hospital, Fudan University, and Shanghai Hebin Rehabilitation Hospital. They were randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine neurological rehabilitation, while the intervention group received additional training with an elbow-wrist functional orthosis on the affected side, for eight weeks. Before and after intervention, the Modified Ashworth Scale (MAS) of the elbow joint, plantar pressure symmetry index (SI), plantar contact area and mean plantar pressure were recorded, and balance and mobility were assessed using the Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-Meter Walk Test (10MWT). ResultsTwo cases dropped out in the control group. After treatment, MAS grades of the elbow joint, forefoot SI, affected side plantar pressure area, BBS scores, TUGT and 10MWT of both groups improved (|Z| > 3.969, |t| > 3.528, P < 0.01), while the hindfoot SI and average pressure of the affected foot improved in the intervention group (∣t∣ > 4.264, P < 0.001). Except for TUGT and 10MWT, the intervention group was superior to the control group (∣Z∣ > 2.030, ∣t∣ > 2.096, P < 0.05). ConclusionThe elbow-wrist functional orthosis can enhance balance function in stroke patients with hemiplegia by reducing upper-limb spasticity, optimizing center-of-gravity distribution, and improving postural control.

ObjectiveTo investigate the variation of drug resistance genes in human immunodeficiency virus (HIV)-1 strains in Huzhou City, Zhejiang Province, so as to provide a basis for guiding the adjustment of treatment plans for ADIS patients or patients infected with HIV. MethodsA total of 555 samples were collected from 396 newly diagnosed HIV/AIDS patients who did not receive antiviral treatment from 2021 to 2023, in addition to 159 HIV/AIDS patients who received antiviral treatment for at least twelve months but failed during the same period.Reverse transcription polymerase chain reaction (RT-PCR) and nested polymerase chain reaction (nested PCR) were used to amplify the pol region gene of HIV-1. Lastly, the sequenced data were submitted to the HIV resistance database of Stanford University in the United States for resistance gene mutation analysis. ResultsDrug resistance mutations were detected in samples from 97 newly diagnosed HIV/AIDS patients and 77 patients with failed treatment, with the main subtypes being CRF01AE and CRF07-BC. The mutation rates of drug resistance genes in the patients untreated and patients with failed treatment were 24.49% (97/396) and 48.43% (77/159), respectively. Drug resistance gene mutations against protease inhibitor (PI), nucleotide reverse transcriptase inhibitor (NRTI), and non-nucleoside reverse transcriptase inhibitor (NNRTI) were detected both in the untreated and failed treatment group. The drug resistance rates of untreated and failed treatment patients were 10.61% (42/396) and 45.28% (72/159), respectively. ConclusionThe pre-treatment drug resistance rate of HIV-1 strains in Huzhou City is at a moderate level, and which is at a relatively low level nationwide after antiviral treatment. The resistance genes in the region exhibit diverse and complex characteristics, and the prevalence of drug resistance is in the process of upward and evolution compared to the monitoring results in the previous years. It is necessary to continue to monitor the occurrence and development of drug resistant strains, and to adjust treatment plans in time to prevent the occurrence of transmissible drug resistance.

Intelligent acupuncture-moxibustion medical equipment is an important force in promoting the inheritance, innovation, and modernization of acupuncture-moxibustion. This paper reviews the development status of intelligent acupuncture-moxibustion medical equipment and related new technologies, as well as the challenges faced. It is found that, with the advancement of technologies such as big data and artificial intelligence, acupuncture-moxibustion medical equipment has shown characteristics of greater precision, miniaturization, intelligence, and portability. However, deficiencies remain in areas such as standardization and regulation, including relatively low rates of effective transformation and a lack of innovation in research outcomes. Therefore, there is an urgent need to formulate corresponding strategies: improving the development of relevant standards for intelligent acupuncture-moxibustion medical equipment, encouraging the integration of medicine and engineering, cultivating interdisciplinary talents, and strengthening the protection of invention patents. It is necessary to establish a demand-oriented pathway connecting "equipment development, equipment evaluation, product formation" through multiple stages such as talent training and research project initiation, thereby promoting the modernization and standardization of intelligent acupuncture-moxibustion medical equipment and supporting the revitalization of traditional medicine.

Objective:To explore the impact of neoadjuvant immunotherapy on the occurrence of low anterior resection syndrome (LARS) in patients with locally advanced rectal cancer who underwent restorative anterior resection, and to analyze associated risk factors.Methods:This study was an observational study. Patients with adenocarcinoma, mucinous adenocarcinoma, or signet ring cell carcinoma of the rectum located 0-10 cm from the anal verge who received neoadjuvant immunotherapy followed by curative restorative anterior resection at Peking University Cancer Hospital between November 2019 and February 2024 were retrospectively examined. Exclusion criteria were as follows: (1) metastasis detected preoperatively;(2) follow-up <1 year or stoma closure <6 months; (3) local recurrence or metastasis during follow-up; and (4) stoma without closure or stoma re-creation. The Chinese version of the LARS questionnaire was used to assess bowel function by telephone interview, and patients were classified based on score into no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30–42 points). The incidence of LARS, major LARS, and associated risk factors were analyzed.Results:A total of 52 patients (34 men) were included for analysis. Mean age was 58.0 ± 9.8 years and mean body mass index was 25.1 ± 2.6 kg/m 2. Median follow-up was 27.5 months (range, 12.0-63.7). Median LARS score was 21 (range, 1-41). Twenty-six patients (50.0%) developed LARS after surgery, and half of these (13 cases) were classified as major LARS. Stool clustering (repeated defecation within 1 hour) was observed in 80.8% (42/52) of patients. Distance between the tumor edge and the dentate line [odds ratio (OR), 3.597; 95% confidence interval (CI), 1.140-11.360; P=0.026], management of the left colic artery (OR, 0.133; 95% CI, 0.026-0.691; P=0.008), and interval of stoma closure (OR, 5.250; 95%CI, 1.381-19.960; P=0.011) were significantly associated with LARS. Interval of stoma closure was significantly associated with major LARS (OR, 4.200; 95%CI, 1.064–16.584; P=0.040). In multivariate logistic regression, ≤3.5 cm between the tumor edge and the dentate line (OR, 7.407; 95%CI, 1.377-40.000; P=0.020), non-preservation of the left colic artery (OR, 8.403; 95%CI, 1.183-58.823; P=0.033) and interval of stoma closure >6 months (OR, 10.865; 95% CI, 2.039-57.896; P=0.005) were independent risk factors for LARS. Interval of stoma closure >6 months (OR, 4.356; 95% CI, 1.105-17.167; P=0.035) were independent risk factors for major LARS. Conclusion:Patients with locally advanced rectal cancer treated with neoadjuvant immunotherapy experienced a high incidence of LARS after curative surgery, with stool clustering as the predominant symptom. Tumor edge–dentate line distance ≤3.5 cm, non-preservation of the left colic artery, and interval of stoma closure >6 months were risk factors for LARS.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.
