ABSTRACT
OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.
ABSTRACT
OBJECTIVE： To investigate the effects of dexmedetomidine combined with mild hypothermia on the levels of High mobility group box 1 protein （HMGB1）， Toll like receptor 4 （TLR4） and Triggering receptor expressed on myeloid cells 1 （Trem-1） in lung tissues of sepsis model rats. METHODS： Totally 100 SD rats were randomly divided into sham operation group （normal saline）， model group （normal saline）， dexmedetomidine group （2 μg/kg）， mild hypothermia group （normal saline+anal temperature 32-35 ℃ caused by whole body spraying of cold water） and combination group （dexmedetomidine 2 μg/kg+anal temperature 32-35 ℃ caused by whole body spraying of cold water）， with 20 rats in each group. Except that sham operation group received sham operation， sepsis model was induced in other groups. After ligation and incision， the corresponding drugs were pumped into the jugular vein and the corresponding body temperature was maintained. Plasma samples were collected 6 h after operation. Interleukin 1 （IL-1）， IL-6， tumor necrosis factor α （TNF-α） were determined by ELISA. The lung wet mass/dry mass ratio （W/D） was calculated by weighing the mass. Lung tissue sections were observed by HE staining， and lung injury scores were scored. The activity of MPO in lung tissue was determined by immunoturbidimetry. The expression of HMGB1，TLR4 and Trem-1 protein was determined by Western blot. RESULTS： Compared with sham operation group， the contents of IL-1， IL-6 and TNF-α， W/D， lung injury score， MPO activity， the protein expression of HMGB1， TLR4 and Trem-1 were increased significantly， with statistical significance （P＜0.05）； lung tissue section showed that alveolar wall was obviously thickened； a large number of inflammatory cells infiltrated； blood vessels were obviously dilated and congested. Compared with model group， above indexes of rats in dexmedetomidine group， mild hypothermia group and combination group were decreased significantly， with statistical significance （P＜0.05）； the degree of pathological changes in lung tissue was significantly reduced. Compared with dexmedetomidine group and mild hypothermia group， above indexes of combination group were decreased more significantly， with statistical significance （P＜0.05）. Alveolar walls were thickened， inflammatory cell infiltration was relieved significantly and no vascular diatation and congestion was found. CONCLUSIONS： Dexmedetomidine combined with mild hypothermia can significantly improve lung injury in sepsis model rats， and down-regulate the protein expression of HMGB1， TLR4 and Trem-1. Therapeutic efficacy of combination therapy is better than single therapy.
ABSTRACT
With more and more international medical students studying medicine in China,international medical education becomes an important part of Chinese medical education.By integration of basic and clinical pharmacology,the teaching mode of theory,experiment,problem based learning and seminar was applied to the international medical students according to their characteristics and specificity.75％,80％ and 70％ of the total international medical students respectively passed the two consecutive final exams and one pharmacology group exam.Through the teaching of pharmacology for international medical students major in MBBS,this author aims to explore the teaching mode of pharmacology for the international medical students.
ABSTRACT
Objective To improve the traditional nursing method in the postoperative children with cheiloplasty. Method Using the arm clipboards in 150 postoperative children with cheiloplasty, and then expanded using in 120 children who have accepted other surgery operation. Observed the nursing effects among these children. Results The nursing effects when using this kind of arm clipboards was significant, the re-injection rate was reduced. Conclusion Using arm clipboards among postoperative children can effective improve the nursing quality, and then increase the satisfaction of patients.
