Surgical treatment of vidianneurectomy and selective vidianneurectomy in 60 cases of refractory allergic rhinitis / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the effect of vidian neurectomy and selective vidian neurectomy in the treatment of moderate and severe persistent allergic rhinitis (AR). Methods: A total of 60 patients with moderate-to-severe persistent AR treated in Zhejiang Provincial Hospital of Integrated Traditional Chinese and Western Medicine from June 2018 to June 2020 were selected, including 28 males and 32 females. A total of 40 cases in the observation group were subjected to vidianneurectomy, while, 20 cases in the control group underwent selective vidianneurectomy. Patients in the two groups were followed up at 6 months, 1 year, and 2 years, respectively, and evaluated according to AR diagnostic and efficacy assessment criteria. Four symptoms of sneezing, clear runny nose, nasal congestion, and nasal itching were scored as efficacy indices before and at 6 months, 1 year, and 2 years after surgery. The regression of the lower turbinate swelling after surgery was assessed by nasal endoscopy or sinus CT. Postoperative tear secretion was followed up in both groups, and patients with dry eyes were counted in combination with ocular symptoms. SPSS 19.0 software was used to statistically analyze the data before and after the surgery and between the two groups. Results: The preoperative, 6-month, 1-year, and 2-year postoperative inferior turbinate signs were (2.73±0.45), (1.20±0.41), (1.25±0.49) and (1.30±0.56) points in the observation group and (2.75±0.44), (1.45±0.69), (1.75±0.72) and (1.90±0.85) points in the control group, respectively, with a statistically significant difference in the between-subjects effect test between the two groups (F=8.28, P<0.05), indicating a more durable surgical effect in the observation group. The total effective rate at 2 years after surgery was 95.0% (38/40) in the observation group and 50% (10/20) in the control group. The difference between the two groups by Fisher's exact test was statistically significant. No dry eye patient was found in either group at a 1.5-year postoperative follow-up. Conclusion: Both vidianneurectomy and selective vidianneurectomy have good recent treatment effects, vidianneurectomy has better long-term curative effects than selective vidianneurectomy.

Effect of SAM junctional tourniquet on respiration when applied in the axilla: A swine model / 中华创伤杂志(英文版)

PURPOSE@#SAM junctional tourniquet (SJT) has been applied to control junctional hemorrhage. However, there is limited information about its safety and efficacy when applied in the axilla. This study aims to investigate the effect of SJT on respiration when used in the axilla in a swine model.@*METHODS@#Eighteen male Yorkshire swines, aged 6-month-old and weighing 55 - 72 kg, were randomized into 3 groups, with 6 in each. An axillary hemorrhage model was established by cutting a 2 mm transverse incision in the axillary artery. Hemorrhagic shock was induced by exsanguinating through the left carotid artery to achieve a controlled volume reduction of 30% of total blood volume. Vascular blocking bands were used to temporarily control axillary hemorrhage before SJT was applied. In Group I, the swine spontaneously breathed, while SJT was applied for 2 h with a pressure of 210 mmHg. In Group II, the swine were mechanically ventilated, and SJT was applied for the same duration and pressure as Group I. In Group III, the swine spontaneously breathed, but the axillary hemorrhage was controlled using vascular blocking bands without SJT compression. The amount of free blood loss was calculated in the axillary wound during the 2 h of hemostasis by SJT application or vascular blocking bands. After then, a temporary vascular shunt was performed in the 3 groups to achieve resuscitation. Pathophysiologic state of each swine was monitored for 1 h with an infusion of 400 mL of autologous whole blood and 500 mL of lactated ringer solution. Tb and T0 represent the time points before and immediate after the 30% volume-controlled hemorrhagic shock, respectively. T30, T60, T90 and T120, denote 30, 60, 90, and 120 min after T0 (hemostasis period), while T150, and T180 denote 150 and 180 min after T0 (resuscitation period). The mean arterial pressure and heart rate were monitored through the right carotid artery catheter. Blood samples were collected at each time point for the analysis of blood gas, complete cell count, serum chemistry, standard coagulation tests, etc., and thromboelastography was conducted subsequently. Movement of the left hemidiaphragm was measured by ultrasonography at Tb and T0 to assess respiration. Data were presented as mean ± standard deviation and analyzed using repeated measures of two-way analysis of variance with pairwise comparisons adjusted using the Bonferroni method. All statistical analyses were processed using GraphPad Prism software.@*RESULTS@#Compared to Tb, a statistically significant increase in the left hemidiaphragm movement at T0 was observed in Groups I and II (both p < 0.001). In Group III, the left hemidiaphragm movement remained unchanged (p = 0.660). Compared to Group I, mechanical ventilation in Group II significantly alleviated the effect of SJT application on the left hemidiaphragm movement (p < 0.001). Blood pressure and heart rate rapidly increased at T0 in all three groups. Respiratory arrest suddenly occurred in Group I after T120, which required immediate manual respiratory assistance. PaO2 in Group I decreased significantly at T120, accompanied by an increase in PaCO2 (both p < 0.001 vs. Groups II and III). Other biochemical metabolic changes were similar among groups. However, in all 3 groups, lactate and potassium increased immediately after 1 min of resuscitation concurrent with a drop in pH. The swine in Group I exhibited the most severe hyperkalemia and metabolic acidosis. The coagulation function test did not show statistically significant differences among three groups at any time point. However, D-dimer levels showed a more than 16-fold increase from T120 to T180 in all groups.@*CONCLUSION@#In the swine model, SJT is effective in controlling axillary hemorrhage during both spontaneous breathing and mechanical ventilation. Mechanical ventilation is found to alleviate the restrictive effect of SJT on thoracic movement without affecting hemostatic efficiency. Therefore, mechanical ventilation could be necessary before SJT removal.

Effect of moxibustion on clinical symptoms, peripheral inflammatory indexes and T lymphocyte subsets in COVID-19 patients / 中国针灸

OBJECTIVE@#To explore the therapeutic effect and the mechanism of the adjuvant treatment with moxibustion on coronavirus disease 2019 (COVID-19).@*METHODS@#A total of 95 patients with COVID-19 were randomly divided into a moxibustion group (45 cases) and a basic treatment group (50 cases). The routine treatment of western medicine was applied in the patients of both groups. In the moxibustion group, on the base of the treatment of western medicine, moxibustion was applied to Dazhui (GV 14), Feishu (BL 13), Qihai (CV 6) and Zusanli (ST 36), once daily and consecutively for 14 days. At the end of treatment courses, clinical symptom scores for cough, asthmatic breathing, chest oppression and short breath, as well as their remission rates were compared between the two groups before and after treatment. Before and after treatment, the white blood cell (WBC) count, the levels of c-reactive protein (CRP) and interleukin-6 (IL-6) and the absolute number of T lymphocyte subsets, i.e. , and of the peripheral blood were compared in the patients between the two groups. The principal component analysis was adopted to analyze the common data extracted from the above 10 clinical indexes variables and comprehensively evaluate the differences in the therapeutic effect of two regimens.@*RESULTS@#The clinical symptom scores were all decreased after treatment in both of the moxibustion group and the basic treatment group as compared with those before treatment (@*CONCLUSION@#On the base of the routine treatment with western medicine, moxibustion therapy supplemented relieves the clinical symptoms, reduces the levels of inflammatory indexes, i.e. IL-6 and CRP as well as improves the absolute number of peripheral T lymphocyte subsets. The clinical therapeutic effect of such regimen with moxibustion supplemented is significantly better than the simple routine treatment of western medicine.
