Pathological myopic choroidal neovascularization(PM-CNV)is a common complication leading to vision loss in patients with pathological myopia.Its pathogenesis involves various factors,including mechanical traction,hypoxia,and inflammation.Anti-vascular endothelial growth factor therapy has been proven to be effective in the treatment of PM-CNV.Clinical trials have demonstrated that anti-vascular endothelial growth factor drugs,such as ranibizumab,aflibercept,and conbercept,can improve the vision of patients with PM-CNV,each with its characteristics and applicable scope.This article reviews the latest advancements in drug treatment for PM-CNV,aiming to provide valuable reference for the clinical management of this disease.

As a physical treatment technique, modified electro-convulsive therapy (MECT) is used to treat mental and certain neurological disorders by causing seizures with short, suitable electrical currents applied to the brain while the patient is under general anesthesia and muscle relaxants. MECT is recognized for its therapeutic efficacy and clinical safety, rendering it one of the most prevalent interventions in psychiatric care. To enhance clinical outcomes and minimize adverse effects, this consensus document delineates the indications, therapeutic parameters, therapeutic procedures, potential adverse effects, and associated management strategies for MECT. These guidelines are informed by the latest clinical research and expert consensus, integrating evidence-based medicine methodologies. The objective is to furnish clinicians with precise operational guidelines and to advance the standardization of MECT practices in clinical settings.

Objective To investigate the effect of acupuncture at Hegu(LI4)on neural activity in the visual cortex of healthy volunteers using functional near-infrared spectroscopy(fNIRS).Methods Each healthy volunteer underwent three sets of trials in a resting state:the LI4 group received acupuncture stimulation at the right Hegu(LI4)acupoint;the negative control was the sham acupoint group(SHAM group);and the positive control was the visual stimulation group(VISUAL group).fNIRS was used to simultaneously monitor changes in oxygenated hemoglobin(Oxy-Hb)levels in the vis-ual cortex during various stages of acupuncture or visual tasks,thereby reflecting the activation level of the visual cortex.The entire acupuncture procedure was performed with the subjects' eyes closed.fNIRS recorded the raw optical density values of hemodynamics in the region of interest(ROI)of the visual cortex during each task phase.The relative coefficientβ value for oxygenated hemoglobin was obtained via Matlab analysis,and the coefficient difference Δβ value between the task period and the baseline period was calculated,representing the degree of change in oxygenated hemoglobin content in-duced by the stimulus,which reflected the change in activation level of the visual cortex after acupuncture or visual stimu-lation.A larger Δβ value indicates a higher degree of visual cortex activation.Generalized estimating equations(GEE)were applied to analyze the differences in visual cortex activation levels among the LI4,SHAM,and VISUAL groups.Results In channels 15 and 17 of the striate area and channels 10 and 13 of the extrastriate area,the Δβ values of sub-jects in the LI4 group during the needle manipulation and withdrawal phases were significantly higher than those in the SHAM group(all P＜0.01).When comparing the Δβ values of the LI4 group during the needle manipulation and withdrawal phases with those of the VISUAL group,under the current sample size,the differences were not statistically significant(all P＞0.05).The Δβ values in both the striate and extrastriate areas of the LI4 group peaked during the needle manipulation phase.Conclusion Acupuncture at Hegu(LI4)can effectively activate the visual cortex in healthy volunteers,with the most significant increase in activation observed during the needle manipulation phase.

Nitric oxide(NO)is an endothelial-derived relaxing factor produced by endothelial cells and catalyzed by nitric oxide synthase(NOS), which is present in many organs and tissues of the human body. NO is a key gaseous signaling molecule that mediates a variety of physiopathological processes in organisms. NO and NOS have many functions including the regulation of vascular tone, the relaxation of smooth muscle, activation of immune responses and modulation of neuro-transmission. They have been used in the treatment of diseases in a certain field. In recent years, the incidence of ophthalmic diseases has been on the rise, and the quality of life of patients has been reduced. However, treatment for most diseases is limited. It is find that NO and NOS can be detected in various tissue of ocular parts, and they are involved in the occurrence and transformation of many ocular surface and fundus diseases. This article reviews the correlation between them and ocular diseases, analyzes the mechanism and principle of the occurrence and development of diseases, and provides new ideas for the clinical treatment of ophthalmic diseases in the future.

Objective:To explore the application effect of hydration therapy in patients with intermittent claudication (IC) of peripheral arterial disease, and to provide reference for clinical application.Methods:A randomized controlled trial method was used to select 86 patients with IC of peripheral arterial disease who attended the Department of Vascular Surgery of Shanxi Bethune Hospital from June to September 2023 as the study subjects by convenience sampling method, and they were divided into the control group and the intervention group by using the method of randomized numerical table, each group had 43 cases. In the control group, routine care was provided, and in the intervention group, hydration therapy was implemented on the basis of the control group. Ankle-brachial index, transcutaneous partial pressure of oxygen, and claudication distance were assessed in both groups 1d before and 6 months after the intervention.Results:Forty-two patients in each group completed the study, 21 males and 21 females, aged (61.33 ± 8.93) years in the intervention group; 24 males and 18 females, aged (61.33 ± 9.01) years in the control group. Compared with the ankle-brachial index, transcutaneous oxygen partial pressure and limp distance of the 2 groups 1 d before intervention, the differences were not statistically significant (all P>0.05), and 6 months after the intervention, the transcutaneous oxygen partial pressure of the patients in the intervention group was (37.69 ± 8.86) mmHg (1 mmHg=0.133 kPa), and that of the control group was (29.69 ± 7.79) mmHg, and the differences between the 2 groups were statistically significant ( t=4.40, P<0.05). The differences in patients′ transcutaneous partial pressure of oxygen and limp distance before and after intervention in the intervention group were -7.00 (-13.00, -1.75) mmHg and -50.00 (-100.00, 0.00) m, respectively, and in the control group were 0.01 (-1.00, 1.00) mmHg and 0.01 (-1.25, 20.00) m, respectively, and the differences between the 2 groups were statistically were statistically significant ( Z=5.59, 4.33, both P<0.05). Conclusions:Hydration therapy improves transcutaneous oxygen partial pressure values and claudication distance in patients with peripheral arterial disease IC, and improves microcirculation of the affected limbs in patients.

Objective: To analyze the clinical manifestation, imaging characteristics and prevention of medication-related osteonecrosis of the jaw (MRONJ) after intravenous bisphosphonate (BP) for cancer patients with bone metastases. Methods: The clinical data and radiographic findings of 6 primary breast cancer patients with bone metastases diagnosed as MRONJ from January 2014 to April 2018 in Shanxi Dayi Hospital were retrospectively analyzed. Results: All 6 patients were female, with the median age of 65.5 years old. All patients had no history of systemic application of hormone therapy, no history of diabetes, no history of radiation therapy, no history of metastasis of the jaw, and no history of infection. The average usage time of BP was 28 months. MRONJ occurred in 2 cases on maxilla and 4 cases on mandible. There were 2 patients with tooth extractions history in BP treatment. Clinical symptoms included maxillofacial pain, loosened teeth, fistula suppuration, and exposed sequestrum. Radiographic findings included osteolysis and bone sclerosis or the mixed manifestation of both, with or without periosteal reaction. In addition, nonhealing tooth sockets and sequestrum separation imaging were also included. Conclusions Tooth extraction is considered as an increased risk for MRONJ in patients with malignant bone metastases after BP therapy. MRONJ is more likely to appear in the mandible, but it can also appear in the maxilla. Early screening and initiation of appropriate dental care are necessary for the patients before using BP therapy.
