Application of buried auricular point combined with Wenjing Sanhan prescription in arteriosclerosis obliterans patients with resting pain

BACKGROUND

Research on the combined use of ear acupoint embedding beans and warming meridians with cold-dispersing formulas for alleviating resting pain in patients with arteriosclerosis obliterans (ASO) remains limited.

AIM

To explore the therapeutic efficacy of auricular point embedding beans combined with Wenjing Sanhan prescription in alleviating resting pain in patients with lower-limb ASO.

METHODS

A total of 100 patients with ASO experiencing resting pain who were treated at our hospital from January 2022 to January 2023 were enrolled. They were randomly allocated into two groups using a double-blind approach. The control group was treated using a warming meridian with a cold-dispersing formula, while the study group received additional treatment with ear acupoint embedding beans. The clinical efficacy, ankle-brachial artery pressure ratio, hemorheological indicators, and traditional Chinese medicine symptom scores were compared between the two groups.

RESULTS

The clinical efficacy rate in the study group was significantly higher (94.00%) than that in the control group (72.00%, P < 0.05). Moreover, the ankle-brachial artery pressure ratio was significantly higher in the study group after treatment (P < 0.05). Hemorheological parameters, including whole blood viscosity, plasma viscosity (1.83 ± 0.11) mPa/s, fibrinogen levels (3.30 ± 0.21) g/L, platelet adhesion rate (49.87% ± 10.51%), and erythrocyte aggregation index (1.79 ± 0) were improved in the study group compared to the control group. In addition, the scores for decreased skin temperature (1.41 ± 0.26), intermittent claudication (1.30 ± 0.20), and resting pain (1.23 ± 0.31) were significantly lower in the study group than those in the control group (all P < 0.05). The level of oxidative stress in the study group also exhibited significant improvement (P < 0.05), and the levels of inflammatory factors were considerably lower than those in the control group.

CONCLUSION

The combination of ear point embedding beans and Wenjing Sanhan prescription demonstrates promising clinical efficacy in alleviating resting pain associated with ASO.

[Effect of blue range light-emitting diode radiation on platelets and blood coagulation factors in patients with chronic ischemia of lower limbs]

Chronic arterial insufficiency of lower limbs (CAILL) is a common cardiovascular disease that affects 200 million subjects worldwide: from 4 to 12% of people aged 55-70 years and 20% - over 70 years. The cause of blood circulation disorder in this disease is usually a complex of pathological changes including abnormality of vessel walls' anatomical structure or integrity, disorder of blood rheological properties and alterations of its thrombotic potential. Thus, the therapy of patients with CAILL aiming at hemostasis and, in particular, platelets' aggregation is one of the most urgent problems of medicine.

OBJECTIVE

To study the effectiveness of blue range visible radiation combined with basic therapy to improve hemostasis in patients with CAILL.

MATERIAL AND METHODS

The number of male patients with CAILL equal 63 aged 43-57 years was examined. Blood flow parameters on a fixed part of femoral artery outside the occlusion area were registered based on subjective criteria, number of painless steps and ultrasound doppler flowmetry according to the Fontaine-Pokrovsky classification. The second degree of ischemia was diagnosed in 38 patients, the third degree - in 25 patients. All patients received basic pharmacotherapy. Patients were divided into 2 groups by simple randomization method: control group included 18 patients with II degree of ischemia and 12 patients with III degree of ischemia who received basic pharmacotherapy combined with photohemotherapy (PHT). A set of commonly used laboratory methods for examination of blood coagulation system was applied to assess the effectiveness of PHT. The number of apparently healthy people equal 26 was examined to evaluate normal value of hemostasiological parameters.

RESULTS

Basic pharmacological treatment had a certain positive effect on studied hemostasis parameters and its thrombotic component. However, they did not differ statistically significantly from similar parameters before treatment on the 14th day after treatment. As a result of comprehensive therapy the changes in hemostasis system had identical and statistically significant in percentage terms changes compared to norm and baseline in patients' subgroups of study group with II and III degrees of ischemia. In addition, most hemostasis parameters in patients with II degree of ischemia were close to those of apparently healthy volunteers. Hemostasis parameters in patients with III degree of ischemia decreased to the levels of patients with II degree of ischemia before treatment.

CONCLUSION

The use of basic pharmacological therapy with optical exposure to blood by blue light allows to correct hemostasis and its thrombotic component in patients with CAILL.

Effect of alprostadil plus cilostazol on the treatment outcomes and inflammatory factors in patients with lower extremity arteriosclerosis obliterans receiving evidence-based care

This study aims to elucidate the effect of alprostadil (ALP) plus cilostazol (CIL) on the treatment outcomes and inflammatory factors in patients with lower extremity arteriosclerosis obliterans (LEASO) receiving evidence-based care. Firstly, 130 patients with LEASO were selected from February 2020 to February 2023 and then randomly divided into two groups with 65 patients each. Excluding the dropouts, 59 patients in the control group (6 cases of dropout) received ALP and 62 patients in the research group (3 cases of dropout) received ALP plus CIL. Both groups were cared for in accordance with the evidence-based care model. Treatment outcomes, arteriosclerosis indexes (blood flow of dorsalis pedis artery [DPA], ankle-brachial index [ABI] and toe-brachial index [TBI]), hemorheological parameters (erythrocyte aggregation index [EAI], erythrocyte deformation index [EDI], high blood viscosity [HBV] and haematocrit [HCT]), inflammatory factors (interleukin [IL]-6, IL-8 and tumour necrosis factor [TNF]-α) and complications (nausea, diarrhoea, headache and transaminase elevation) were compared between the control and research groups. Results show that the overall response rate was markedly higher in the research group (90.32%) than in the control group (74.58%). Additionally, the blood flow of DPA, ABI and TBI in the research group significantly increased after the treatment and were higher than those in the control group. Meanwhile, the EAI, EDI, HBV, HCT, IL-6, IL-8 and TNF-α were significantly lower. The two groups did not differ markedly in the complication rate. The above findings suggest that ALP plus CIL is effective for patients with LEASO receiving evidence-based care. It can significantly improve arteriosclerosis indexes and hemorheological parameters while inhibiting serum inflammatory responses, with some certain safety.

Clinical Efficacy of Interventional Therapy on Lower Extremity Arteriosclerosis Obliterans and Prognostic Factors

Objective

This study was designed to analyse the clinical efficacy of interventional therapy on lower extremity arteriosclerosis obliterans (LEASO) and prognostic factors.

Methods

A total of 122 patients with LEASO diagnosed in our hospital from March 2017 to March 2019 were retrospectively analysed. Among them, 72 patients who received conservative therapy were assigned to a conservative group, and 50 patients who received interventional therapy additionally based on conservative therapy were assigned to an intervention group. The short-term (12 weeks after therapy) and long-term (3 years after therapy) clinical efficacies on the two groups were compared. Death, amputation, and vascular restenosis (vascular stenosis > 50% in computed tomography reexamination) were defined as unfavourable outcomes, and Cox regression was conducted to analyze the factors influencing the prognosis of patients. The incidence of adverse events in the two groups within 3 years was compared and statistically analyzed. Additionally, the hospital stay, therapy cost, claudication distance, and ankle brachial index were compared between the two groups.

Results

After therapy, the conservative group showed a notably lower total effective rate than the intervention group (P < 0.05), but the clinical efficacy after 3 years was similar between the two groups (P > 0.05). Additionally, the conservative group experienced notably longer hospital stay than the intervention group (P < 0.05), and cost less in treatment than the intervention group (P < 0.05). However, the conservative group experienced a notably shorter claudication distance and showed a notably lower ankle brachial index than the intervention group (P < 0.05). The two groups were not significantly different in mortality, amputation rate, and vascular restenosis rate (P > 0.05). Moreover, Cox regression analysis revealed that age and conservative therapy were independent risk factors for the prognosis of patients (P < 0.05).

Conclusion

Interventional therapy can substantially improve the short-term efficacy and prognosis of patients with LEASO, but the cost is high, so the therapeutic regimen should be selected according to the patient's economic condition.
