ABSTRACT
Objective:To evaluate the clinical efficacy of Guizhi Mahuang Geban Decoction combined with conventional western medicine in the treatment of post infections cough (PIC), and to explore the mechanism.Methods:A total of 100 PIC patients in our hospital from January 2020 to July 2021 who met the inclusion criteria were divided into 2 groups according to the random number table method, with 50 in each group. The control group was treated with conventional western medicine, and the study group was treated with Guizhi Mahuang Geban Decoction and the treatment of the control group. Both groups were treated for 10 days. TCM symptom scores were performed before and after treatment. The levels of neurokinin A (NKA), substance P (SP), neurokinin B (NKB) and calcitonin gene related peptide (CGRP) were detected by ELISA. Adverse events were recorded and clinical effects were evaluated.Results:The total clinical effective rate was 90.0% (45/50) in the study group and 68.0% (34/50) in the control group, and there was significant difference between the two groups ( χ2=7.29, P=0.007). The scores of cough, expectoration, pharyngeal itch and total score in the study group were significantly lower than those in the control group ( t values were 8.04, 6.30, 9.03, 9.71, all Ps<0.01). After treatment, NKA [(86.08±18.21) ng/L vs. (137.68±28.29) ng/L, t=10.85], SP [(54.23±11.28) ng/L vs. (71.75±15.34) ng/L, t=6.51], NKB [(96.15±20.19) ng/L vs. (149.84±30.22) ng/L, t=10.45], CGRP [(62.93±18.35) ng/L vs. (89.59±23.25) ng/L, t=6.37] levels in the study group were significantly lower than those in the control group ( P<0.01). The incidence of adverse events was 8.0% (4/50) in the control group and 10.0% (5/50) in the study group, and there was no significant difference between the two groups ( χ2=0.13, P=0.727). Conclusions:Compared with western medicine alone, Guizhi Mahuang Geban Decoction combined with western medicine can rapidly improve patients' symptoms, improve curative effect and have better safety for PIC. Its mechanism may be related to the regulation of NKA, SP, NKB and CGRP levels.
ABSTRACT
Objective To explore the impact of different doses of dexmedetomidine on the anesthetic sedative and analgesic effect of anesthesia agents in hysterectomy of patients with uterine fibroids under laparoscopy.Methods 90 patients with uterine fibroids with ASA class Ⅰ or Ⅱ who were going to undergoing general intravenous anesthesia laparoscopic hysterectomy were selected and they were divided into group A (dexmedetomidine 0.4μg·kg-1·h-1,n=30) and group B (dexmedetomidine 0.2μg·kg-1·h-1,n=30) and group C (no dexmedetomidine,n=30) by digital random method.The analgesia effect (VAS score) of group A,group B and group C preoperation and postoperative 1h,12h and 24h,and the sedation (Ramsay sedation score) were compared.General information,postoperative blood pressure,heart rate,pulse oxygen saturation,postoperative patients'' satisfaction on analgesic effect and the sedation effect and adverse reactions of the three groups were also compared.Results Age,body mass index and other basic information of three groups had no statistically significant differences (all P＞0.05).The preoperative VAS score of the three groups also had no statistically significant difference (F=0.625,P＞0.05).Postoperative 12h,24h,the VAS scores of group A and group B were lower than those of C group,which of group A were lower than group B (F=11.250,P＜0.05,F=21.181,P＜0.05).The Ramsay sedation score was higher than that of C group[(3.67±0.18) vs.(2.13±0.11)].The satisfaction of group A was significantly higher than group B and group C (96.67％ vs.73.33％,46.67％,χ2=25.953).The Ramsay sedation score and satisfaction were higher than those of group B (all P＜0.05).There were no significant differences in blood pressure (F=0.362,P＞0.05),pulse oxygen saturation (F=0.978,P＞0.05) and heart rate among the three groups before and after operation (F=1.268,P＞0.05).There was no obvious adverse reaction in the three groups.Conclusion Dexmedetomidine can promote anesthetic sedative and analgesic effect of anesthesia agents in hysterectomy of patients with uterine fibroids under laparoscopy,and the dose 0.4μg·kg-1·h-1 of dexmedetomidine has better effect,feasibility and safety,it is worthy of clinical promotion.
