ABSTRACT
Objective:To explore the application effect of ultrasound-guided pectoralis Ⅱ(PECS-Ⅱ)blocks anesthesia in benign tumor resection of breast.Methods:A total of 60 female patients who underwent benign tumor resection of breast were selected from Maternity and Child Care Center of Qinhuangdao from January 2021 to December 2021,and they were divided into the thoracic nerve block group(nerve block group)and local infiltration anesthesia group(local anesthesia group)according to the random number table method.The nerve block group used ultrasound-guided PECS-Ⅱ anesthesia,and the local anesthesia group used local infiltration anesthesia for tumor.The hemodynamic indicators,postoperative visual analogue score,first intervention time of postoperative analgesic drugs,and the use of sufentanil within 24 hours after surgery were compared and analyzed between the two groups of patients.Results:The average operation time of the nerve block group was(127.32±34.56)min,and the difference of that between the nerve block group and local anesthesia group(128.11±33.84)min was no statistically significant(P>0.05).The differences of the heart rate(HR)and mean arterial pressure(MAP)before anesthesia(T0)between two groups of patients were not statistically significant(P>0.05).The HR and MAP levels at the time of skin incision(T1),at the 0.5 h after the surgery was conducted(T2)and the time of completing surgery(T3)in nerve block group were significantly lower than those of the local anesthesia group,respectively.The differences were statistically significant(tHR=5.709,5.836,5.662,tMAP=3.501,3.223,3.128,P<0.05),respectively.Compared with the local anesthesia group,the pain level at the same time point in the nerve block group was significantly reduced,and the difference was statistically significant(t=4.501,6.575,8.197,8.262,P<0.05),respectively.The intervention time of analgesic medication at the first time of the nerve block group was significantly later than that of the local anesthesia group,and the consumption of sufentanil within 24 hours after surgery of the nerve block group was also significantly reduced,and the differences of them were statistically significant(t=13.741,9.482,P<0.05),respectively.Conclusion:Ultrasound-guided PECS-Ⅱ can effectively relieve postoperatively early pain in patients with benign tumors of breast,and delay the intervention time of postoperative analgesic medication,and reduce the intake amount of opioid drugs.
ABSTRACT
Objective To explore the psychological stress of young nurses facing patients' death. Methods Young nurses in emergency department, ICU and hospice care ward (96 cases, research group) and young nurses in other departments(94 cases,control group)from 8 general hospitals were investigated by self-rating anxiety scale (SAS)and serf-rating depression scale (SDS).The results underwent comparison and analysis. Results SAS and SDS score,incidence of anxiety and depression in the research group were higher than those of the control group (P ＜ 0.05). Conclusions Young nurses who face patients' death frequently have high incidence rate of psychological stress.They show low psychological health level which deserves the close attention of nursing managers.
ABSTRACT
OBJECTIVE:To discuss the effects of Rujieping capsule on estrogen receptor(ER) and progesteron receptor(PR) of pathological tissues in rats with hyperplasia of mammary glands.METHODS:The rats were injected i.m with Estradiol benzoate injection for 25 days followed by the injection of Progesterone injection i.m for 5 days to establish the model of hyperplasia of mammary glands.Which were treated with high and low doses of Rujieping capsule respectively for 30 days with tamoxifen as positive control.RESULTS:Both tamoxifen and high and low doses of Rujieping capsules could lessen the symptoms of red swelling of nipples or hyperplasia of mammary glands,lower the levels of E2 and PRL,enhance the level of progestone,lower the index of uterus,markedly reduce the number of layers of the ductal epithelial cells,reduce the levels of ER and PR in mammary glands,and suppress mammoplasia.CONCLUSION:Rujieping capsules is effective in the treatment of hyperplasia of mammary glands in rats by regulating the level of estrogen and improve pathomorphologic change of hyperplastic mammary glands.
ABSTRACT
OBJECTIVE:To study the immunoregularoty effect of Lappaconitine in S180 tumor-bearing mice.METHODS: Each mouse was inoculated hypodermically with S180 tumor cells and normal sodium suspension,24 hours later,all the mice were injected i.m.with Lappaconitine q.d for 10 consecutive days.The immune function of the S180 tumor-bearing mice was detected.RESULTS: In Lappaconitine-treated mice,serum IgG level was heightened significantly;the 2,4-DNFB-induced delayed type hypersensitivity was enhanced;the induction of transformation of lymphocytes into lymphoblast was achieved;the phagocytic function of reticuloendothelial system was enhanced significantly,and the immune function of red cells was promoted.CONCLUSION: Lappaconitine could inhibit the growth of S180 tumor cells and significantly enhance the cellular immune function of S180 tumor-bearing mice.
ABSTRACT
OBJECTIVE:To optimize the basic formula of Compound Salicylic Acid and Chloramphenicol Gel with orthogonal design test.METHODS:The closage of CMC-Na、glycerin and ethanol were taken as the review object with the oligation grade as the evaluation index to conduct L9(33) orthogonal test and the contents of salicyclic acid and the chloramphenicol were determined by HPLC. RESULTS: The optimized basic formula was as follows: sodium carboxymethylcellulose 3 g, glycerine 10 g, and alcohol 35 mL.The average recovery of Salicylic Acid and Chloramphenicol were 99.1% and 101.6%,the RSD were 0.8% and 1.3%.CONCLUSION: The basic formula optimized with orthogonal test is proved to be stable and serve as theoretic basis for the industrialized production of this preparation.
