Objective:To compare the quality of sleep and rehabilitation after routine surgery versus day surgery in pediatric patients with snoring.Methods:This was a prospective study.Seventy pediatric patients with snoring, aged 4-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing adenoidectomy and/or tonsillectomy in the Guangzhou Women and Children′s Medical Center from March to June 2023, were divided into routine surgery group (group R) and day surgery group (group D), with 35 cases in each group. A sleep-detecting bracelet was used to monitor the sleep status. The proportion of deep sleep, light sleep and rapid eye movement, sleep continuity score and the maximum and minimum heart rate were recorded on the night before surgery, the first and second night after surgery. Rehabilitation was assessed using Quality of Recovery-15 at 1 day before surgery and 24 and 48 h and 28 days after surgery.Results:Compared with group R, the maximum heart rate at the night before surgery was significantly decreased, the proportion of light sleep on the second night after surgery was increased, the proportion of rapid eye movement sleep on the second night after surgery was decreased, the scores for items on " getting support from hospital doctors and nurses", " feeling comfortable and in control", and " having a feeling of general well-being" and the total score of Quality of Recovery-15 were significantly decreased at 24 and 48 h after operation, and the score for items on " feeling rested" and " have had a good sleep" at 48 h after surgery was decreased in group D ( P<0.05). Conclusions:Pediatric patients with snoring have poor quality of early sleep and rehabilitation after day surgery compared with routine surgery.

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.

Tear film hyperosmolarity plays a core role in the development of dry eye disease (DED) by mediating the disruption of ocular surface homeostasis and triggering inflammation in ocular surface epithelium. In this study, the mechanisms involving the hyperosmolar microenvironment, glycolysis mediating metabolic reprogramming, and pyroptosis were explored clinically, in vitro, and in vivo. Data from DED clinical samples indicated that the expression of glycolysis and pyroptosis-related genes, including PKM2 and GSDMD, was significantly upregulated and that the secretion of IL-1β significantly increased. In vitro, the indirect coculture of macrophages derived from THP-1 and human corneal epithelial cells (HCECs) was used to discuss the interaction among cells. The hyperosmolar environment was found to greatly induce HCECs' metabolic reprogramming, which may be the primary cause of the subsequent inflammation in macrophages upon the activation of the related gene and protein expression. 2-Deoxy-d-glucose (2-DG) could inhibit the glycolysis of HCECs and subsequently suppress the pyroptosis of macrophages. In vivo, 2-DG showed potential efficacy in relieving DED activity and could significantly reduce the overexpression of genes and proteins related to glycolysis and pyroptosis. In summary, our findings suggested that hyperosmolar-induced glycolytic reprogramming played an active role in promoting DED inflammation by mediating pyroptosis.

Objective: To observe the effect of moxibustion on the colonic mucosal barrier of rats with ulcerative colitis (UC) induced by dextran sulfate sodium (DSS). Methods: Forty male Sprague-Dawley rats were randomly divided into a normal group and a modeling group, with 20 rats in each group. Rats in the modeling group were subjected to preparing experimental UC models by drinking 4％ DSS for seven consecutive days. Two modeled rats and two normal rats were randomly selected for model identification. After the success of UC model was confirmed, the remaining 18 modeled rats were randomly divided into three groups, a model group, a model + herbal cake-partitioned moxibustion group, and a model + mild moxibustion group, with six rats in each group; the remaining normal rats were randomly divided into three groups, a normal group, a normal + herbal cake-partitioned moxibustion group, and a normal + mild moxibustion group, with six rats in each group. After 7 d of intervention with the herbal cake-partitioned moxibustion or the mild moxibustion, hematoxylin-eosin (HE) staining technique was used to observe the pathological changes of colon tissue under a light microscope; Western blotting and/or immunohistochemical techniques were used to detect the protein expression levels of Occludin, Claudin, junction adhesion molecular 1 (JAM1), mucin 2 (MUC2), and transforming growth factor beta1 (TGF-β1) in rat colon tissue. Results: Compared with the normal group, the colon tissue was severely damaged, the pathological score was significantly increased, and the protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 were significantly decreased in the model group (P<0.01); while there were no significant differences in the colonic histopathological score, protein expression levels of Occludin, Claudin, JAM1, MUC2, and TGF-β1 in the normal + herbal cake-partitioned moxibustion group and the normal + mild moxibustion group (P>0.05). Compared with the model group, the model + herbal cake-partitioned moxibustion group and the model + mild moxibustion group showed repaired colon tissue, ulcer healing, significantly reduced pathological score, and significantly increased protein expression levels of JAM1, MUC2, and TGF-β1 (P<0.05); the Occludin protein expression level in the colon tissue of the model + mild moxibustion group was increased (P<0.01). Conclusion: Neither herbal cake-partitioned moxibustion nor mild moxibustion influences the colonic histopathology and intestinal mucosal barrier-related protein expression in the normal rats; both herbal cake-partitioned moxibustion and mild moxibustion can up-regulate the protein expression levels of JAM1, MUC2, and TGF-β1 in the colon tissue of UC rats. Mild moxibustion can up-regulate Occludin protein expression. This may be a mechanism of moxibustion in reducing colonic mucosa inflammation in UC.

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.

Objective To evaluate the effects of different fluid therapy protocols on postoperative nausea and vomiting (PONV) in pediatric patients undergoing ambulatory surgery.Methods A total of 160 pediatric patients,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 3-7 yr,weighing 14-24 kg,with body mass index ＜30 kg/m2,undergoing elective lower abdominal ambulatory surgery,were randomized into Ⅰ and Ⅱ groups (n=80 each) using a random number table method.Lactated Ringer's solution 10 ml · kg-1 · h-1 and 30 ml · kg-1 · h-1 were intravenously infused in group Ⅰ and group Ⅱ,respectively.Ibuprofen 20 mg/kg was given orally after operation to maintain Face Legs Activity Cry Consolability score ＜4.The development of PONV and thirst and requirement for antiemetics was recorded within 24 h postoperatively.The time of first PONV,time of first thirst and score for satisfaction of family members were also recorded.Results Compared with group Ⅰ,the incidence of PONV and thirst was significantly decreased,the time of first requirement for antiemetics and time of first thirst were prolonged,and the score for satisfaction of family members was increased (P＜ 0.05),and no significant change was found in the requirement for antiemetics in group Ⅱ (P＞0.05).Conclusion Intravenously infusing fluid 30 ml · kg-1 · h-1 can decrease the occurrence of PONV when compared with intravenously infusing fluid 10 ml · kg-1 · h-1 in pediatric patients undergoing ambulatory surgery.

Objective: To explore the relationship between glycemic control and visceral adiposity index (VAI) among type 2 diabetes mellitus (T2DM) patients.Methods: A community-based epidemiological field study for patients with T2DM aged ≥ 40 years was conducted in China.Every participant underwent physical examinations, biochemical tests of fasting glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and so on, and a questionnaire, including anthropometric characteristics, lifestyle, disease history, family history, and medication use.Those participants with HbA1c ≥7.0% were classified as the poorly controlled in our analysis of relationship between glycemic control and VAI.Anthropometric characteristics, lifestyle, and biochemical indexes of the participants were compared among the groups of different VAI levels.Logistic models were applied in multiple analysis adjusting for possible confounders.Results: A total of 1 607 patients with T2DM were recruited in our analysis with a mean age of (59.4±8.1) years and an average T2DM duration of (7.0±6.4) years.Among them, 78.3% were on hypoglycemic therapy.The cutoff points of quartiles of VAI were calculated for the males and females, respectively.According to the ascending order of the quartiles of VAI, the participants were divided into four groups, i.e.Q1, Q2, Q3, and Q4.The poor glycemic control rate for these groups were 60.6%, 65.7%, 70.1%, and 71.0%, respectively (Trend χ2=12.20, P<0.001).After adjustment for age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), LDL-C, smoking, cardio-cerebral vascular disease (CVD) history, hypoglycemic therapy, T2DM duration, and family history of diabetes, the Logistic regression models showed that the glycemic control rate was significantly associated with VAI levels among the patients with T2DM.Compared with the participants in group Q1, the ORs of poor glycemic control for those in groups Q2, Q3, and Q4 were 1.239 (95%CI 0.918 to 1.672), 1.513 (95%CI 1.117 to 2.050), and 1.535 (95%CI 1.128to 2.088), respectively (trend P=0.003).With each quartile increase in VAI, the OR of poor glycemic control was 1.162 (95%CI 1.054 to 1.282).Conclusion: The glycemic control among the patients with T2DM is significantly associated with VAI.High level of VAI is an indicator of poor glycemic control.

Objective:To explore the correlation between glycemic control of type 2 diabetes mellitus (T2DM) patients and brachial-ankle pulse velocity (baPWV). Methods:A community-based cross-sec-tional study was conducted in Beijing, China. Every subject underwent physical examinations, glycated hemoglobin ( HbA1 c ) , blood lipid and baPWV measurements and completed a standardized question-naire. T2DM patients were divided into well controlled and poorly controlled groups according to HbA1c levels. The correlation between glycemic control of T2DM patients and baPWV was analyzed. Results:In this study, 1 341 subjects were recruited, including 733 T2DM patients and 608 non-diabetes sub-jects. Compared with non-diabetes subjects, abnormal baPWV ( baPWV≥1 700 cm/s) rate for T2DM patients was higher (40. 8% vs. 26. 8%, P<0. 001). With HbA1c<6. 5% or <7. 0% as the aim of glycemic control in T2DM patients, the abnormal baPWV rates for non-diabetes subjects, well controlled and poorly controlled T2DM patients were significantly different (non-diabetes vs. HbA1c<6. 5% T2DM vs. HbA1c≥6. 5% T2DM: 26. 8% vs. 32. 8% vs. 42. 6%, P <0. 001; non-diabetes vs. HbA1c <7. 0% T2DM vs. HbA1c≥7. 0% T2DM:26. 8% vs. 36. 1% vs. 43. 4%, P<0. 001). After being ad-justed for gender, age, smoking status, diabetes mellitus family history, T2DM duration, cardiovascular diseases ( CVD ) , waist hip ratio ( WHR ) , systolic blood pressure ( SBP ) , diastolic blood pressure ( DBP) , total triglycerides ( TG) , high density lipoprotein cholesterol ( HDL-C) , and low density lipo-protein cholesterol ( LDL-C ) , the Logistic regression models suggested that glycemic control status of T2DM patients was associated with abnormal baPWV. Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1 c <6 . 5% T2 DM patients and HbA1 c≥6 . 5% T2 DM patients were 0 . 927 (95%CI 0. 560-1. 537) and 1. 826 (95%CI 1. 287-2. 591). Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<7. 0% T2DM patients and HbA1c≥7. 0% T2DM patients were 1. 210 (95%CI 0. 808-1. 811) and 1. 898 (95%CI 1. 313-2. 745). Conclusion:The glycemic con-trol status of T2DM patients from communities is significantly associated with baPWV. Poor glycemic con-trol is a risk factor for abnormal baPWV. Keeping HbA1c under control might lower the risk of cardiovas-cular diseases in T2DM patients.
