Objective:To evaluate the effect of buccal acupuncture on analgesia after tonsilloadenoidectomy in pediatric patients.Methods:This was a randomized controlled study. One hundred and twenty-six American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ pediatric patients, aged 3-12 yr, weighing 12-34 kg, with body mass index <30 kg/m 2, undergoing elective tonsilloadenoidectomy with general anesthesia, were divided into 2 groups ( n=63 each) by the random number table method: buccal acupuncture group (group B) and control group (group C). All pediatric patients received the same anesthesia induction and intraoperative anesthesia maintenance. The concentration of sevoflurane was adjusted to keep the fluctuation amplitude of vital sign parameters within 20% of the baseline value. After surgery, the drug was immediately stopped and the children were transferred to the postanesthesia care unit for resuscitation under general anesthesia. In group B, the bilateral neck points, upper neck points, hologram points on the head and Zhongjiao points were selected before removal of the tracheal catheter, and disposable acupuncture needles were inserted directly into the acupoints and remained for 20-30 min. Group C received no buccal acupuncture. The pain Assessment Scale (FLACC) was used to assess the severity of postoperative pain. The postoperative agitation score was evaluated by Aono four-point rating method to evaluate the occurrence of agitation. The effective pressing times of patient-controlled analgesia, rescue analgesia and occurrence of nausea and vomiting within 48 h after operation were recorded. The occurrence of bleeding, infection and broken needle at acupuncture sites was recorded. Results:Compared with group C, the effective pressing times of patient-controlled analgesia and incidence of nausea and vomiting were significantly decreased in group B ( P<0.05). There was no significant difference in the rate of rescue analgesia and incidence of postoperative agitation between the two groups ( P>0.05). No infection or broken needle was found at acupuncture sites after buccal acupuncture, only 2 cases had slight bleeding at the puncture site, and there was no abnormality after pressing in group B. Conclusions:Buccal acupuncture can enhance the analgesic effect after tonsilloadenoidectomy in pediatric patients.

Objective:To evaluate the efficacy of auricular acupoint pressure therapy combined with intranasal dexmedetomidine for transthoracic echocardiography in pediatric patients.Methods:A total of 117 pediatric patients with congenital heart disease, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, aged 3-36 months, weighing 5-20 kg, scheduled for elective transthoracic echocardiography under outpatient sedation, were selected.Transthoracic echocardiography was performed under sedation using intranasally administered dexmedetomidine or using auricular acupoint pressure therapy combined with intranasal dexmedetomidine.The interval between the two sedation methods was at least 1 week.Intranasal dexmedetomidine: Dexmedetomidine 3 μg/kg was administered to both nostrils via a nebulizer, with 1/2 dose in each nostril.Intranasal dexmedetomidine combined with auricular acupoint pressure: auricular acupressure with Wang Bu Liu Xing (semen vaccariae) seeds was used at the auricular acupoints.After each acupoint was rubbed for about 1 min, dexmedetomidine 3 μg/kg was administered to both nostrils via a nebulizer, with 1/2 dose in each nostril.After the examination, auricular acupoint pressure therapy was continued at home, and pressing-rubbing at the acupoints was manipulated for 3 times daily, one of which was performed at 30 min before going to bed, for 3 consecutive days.When the University of Michigan Sedation Scale score≥2 and body movement score ≥2 within 30 min after giving dexmedetomidine, sedation was considered to be successful.The onset time of sedation, examination time, waiting time, recovery time and the success of sedation were recorded.The incidence of adverse reactions such as bradycardia, hypotension, hypertension, hypoxemia, nausea and vomiting, respiratory depression, restlessness, hyperactivity, action imbalances and allergic reaction were recorded within 24 h after administration of dexmedetomidine.Time to recovery and improvement of sleep quality at night were recorded.Results:Compared with intranasal dexmedetomidine, the successful rate of sedation and incidence of improvement of sleep quality at night were significantly increased ( P<0.05), and no significant change was found in adverse reactions using intranasal dexmedetomidine combined with auricular acupoint pressure ( P>0.05). Conclusion:Intranasal dexmedetomidine combined with auricular acupoint pressure therapy can increase the successful rate of sedation and improve the sleep quality at night in pediatric patients undergoing transthoracic echocardiography when compared to intranasal dexmedetomidine.

Background: Studies have shown that abnormal expression of circular RNA (circRNA) is closely related to the development, progress and prognosis of a variety of tumors, and is an ideal diagnostic indicator and therapeutic target. However, the role of circRNA in the development and progress of pancreatic cancer needs to be further explored. Aims: To investigate the expression of circ-RANBP1 in pancreatic cancer tissue and its effect on pancreatic cancer cell proliferation, migration and invasion. Methods: The expression of circ-RANBP1 in pancreatic cancer tissue and normal para-cancerous tissue was detected by in situ hybridization. MIA PaCa-2 cells and SW 1990 cells were cultured, and transfected with knockdown oligomer and overexpressed plasmid of circ-RANBP1, respectively, and corresponding control groups were served. Expression of circ-RANBP1 in pancreatic cancer cells was detected by qRT-PCR. EdU method was used to detect the effect of circ-RANBP1 on cell proliferation. Transwell assay was used to detect the effect of circ-RANBP1 on cell migration and invasion. Western blotting and immunofluorescence were used to detect the effect of circ-RANBP1 on epithelial-mesenchymal transition (EMT). Angiogenesis assay was used to explore the effect of circ-RANBP1 on angiogenesis ability. Results: The expression of circ-RANBP1 was significantly increased in pancreatic cancer tissue when compared with paired normal tissues, and was closely associated with poor prognosis of patients. Circ-RANBP1 knockdown inhibited the proliferation of MIA PaCa-2 cells, while overexpression of circ-RANBP1 promoted the proliferation of SW 1990 cells. Compared with control group, circ-RANBP1 knockdown suppressed the migration and invasion of MIA PaCa-2 cells, and overexpression of circ-RANBP1 promoted the migration and invasion of SW 1990 cells. Knockdown of circ-RANBP1 could inhibit EMT, while circ-RANBP1 overexpression showed opposite effect. Inhibition of circ-RANBP1 significantly reduced angiogenesis, while overexpression of circ-RANBP1 significantly enhanced angiogenesis. Conclusions: Circ-RANBP1 is highly expressed in pancreatic cancer tissue, and can promote the proliferation, migration, invasion, EMT and angiogenesis of pancreatic cancer cells.
