Objective:To investigate the clinical efficacy of different doses of budesonide/formoterol in the treatment of an acute exacerbation of chronic obstructive pulmonary disease in patients.Methods:A total of 200 inpatients with an acute exacerbation of chronic obstructive pulmonary disease graded C/D by global initiative for chronic obstructive lung disease (GOLD) staging system who received treatment in Jiuquan City People's Hospital, China from January to December in 2019 were included in this study. They were randomly divided into a control group and a treatment group ( n = 100/group). Based on anti-infection and expectorant treatment, the treatment group was given inhalation therapy (higher dose budesonide/formoterol, 320 μg/9 μg), while the control group was identically given inhalation therapy (lower dose budesonide/formoterol, 160 μg/4.5 μg), with a total course of 9 days in each group. Before treatment and at 5 and 9 days of treatment, procalcitonin (PCT), high-sensitivity C-reactive protein (hs-CRP), fractional exhaled nitric oxide (FeNO), percentage of eosinophils (EO%), partial pressure of oxygen (PaO 2), lactic acid, interleulin-6 (IL-6), forced expiratory volume in 1 second (FEV 1), the ratio of FEV 1/ forced vital capacity (FVC) were monitored in each group. COPD assessment test (CAT) score, modified Medical Research Council (mMRC) dyspnea score, 6-minute walking test (6MWT), and symptom improvement were determined in each group. Results:Before treatment, there were no significant differences in PCT and PaO 2 between the control and treatment groups (both P > 0.05). There were significant differences in PCT, PaO 2, FeNO, hs-CRP, E0 (%), IL-6, FEV 1, FEV 1/FVC, 6MWT, mMRC, cough, expectoration, shortness of breath and CAT score measured at 5 days of treatment between the treatment and control groups ( t = 2.416, 3.289, 3.982, 4.871, 3.332, 4.098, 5.253, 6.214, 3.843, 7.268, 5.387, 7.392, 5.398, 6.349, all P < 0.05). There were significant differences in PCT, PaO 2, FeNO, hs-CRP, E0 (%), IL-6, FEV 1/FVC, FEV 1, 6MWT, mMRC, cough, expectoration, shortness of breath and CAT score measured at 9 days of treatment between the treatment and control groups ( t = 2.508, 4.032, 2.948, 3.527, 3.118, 5.251, 5.325, 6.338, 2.907, 6.289, 3.246, 2.084, 2.151, 2.527, all P < 0.05). At 5 days of treatment, lactic acid level in the observation group was significantly lower than that in the control group ( t = 4.341, P < 0.05). At 9 days of treatment, there was no significant difference in lactic acid level between the control and observation groups ( t = 1.173, P > 0.05). There was no significant difference in the incidence of adverse reactions between the control and treatment groups [4%(4/100) vs. 5%(5/100), P > 0.05]. Conclusion:Inhalation of high doses of budesonide/formoterol can greatly improve pulmonary function, 6MWT performance, decrease mMRC and CAT scores, alleviate cough, expectoration, shortness of breath, and decrease serum levels of FeNO, hs-CRP, E0(%), IL-6 and other inflammatory factors. Inhalation of higher doses of budesonide/formoterol exhibits better efficacy in the treatment of an acute exacerbation of chronic obstructive pulmonary disease in patients than inhalation of lower doses of budesonide/formoterol.

Objective To evaluate the efficacy of acupuncture combined with tropisetron in treating nausea and vomiting induced by carboprost tromethamine in cesarean section. Methods Sixty-six patients aged 22-40 yr who received carboprost tromethamine and developed nausea and vomiting during cesarean section under lumbar anesthesia, were randomly divided into 3 groups(n=22 each): acupuncture group (group A), tropisetron group(group T)and acupuncture+ tropisetron group(group AT). In group A, 09% normal saline 2 ml was intravenously injected immediately, acupuncture was given at Renzhong, Neiguan and Hegu acupoints with lifting thrusting twirling the acupuncture needle for 10 min. In group T, tropisetron 10 mg was intravenously injected immediately, the needle was placed on Renzhong, Neiguan and Hegu skin surface. In group AT, tropisetron 10 mg was intravenously injected immediately, acupunc-ture was given at Renzhong, Neiguan and Hegu acupoints with lifting thrusting twirling the acupuncture nee-dle for 10 min. The nausea and vomiting score was assessed before anesthesia induction(T0), when nause-a or vomiting occurred(T1)and at 1, 3, 5 and 15 min after acupuncture or administration(T1-5). The degree of patient′s satisfaction with therapeutic effect was recorded. Results Compared with group A, the nausea and vomiting scores were significantly decreased at T4, and the patient's satisfaction score was in-creased in group AT(P<005). Compared with group T, the nausea and vomiting scores were significantly decreased at T2-4and the patient's satisfaction score was increased in group AT(P <005). Conclusion Acupuncture combined with ondansetron can quickly and effectively relieve the nausea and vomiting induced by carboprost tromethamine during cesarean section.

Objective:To evaluate the improved efficacy of transversus abdominal plane (TAP)-rectus sheath (RS) block combined with general anesthesia in the patients undergoing laparoscopic pancreaticoduodenectomy.Methods:Fifty-six American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged 45-64 yr, with body mass index of 18-25 kg/m 2, scheduled for elective laparoscopic pancreaticoduodenectomy, were divided into 2 groups ( n=28 each) using a random number table method: general anesthesia group (group G) and TAP-RS block plus general anesthesia group (group TRG). In group TRG, after induction of general anesthesia, bilateral TAP-RS block was performed with 0.375% ropivacaine mixed with 0.5 μg/kg dexmedetomidine under ultrasound guidance, 20 ml was injected into the plane of bilateral transverse abdominis, and 10 ml was injected into the posterior sheath of the bilateral rectus abdominis, and the tube was placed on the plane of the transverse abdominis, and 5 ml/h was continuously pumped after operation.In both groups, anesthesia was induced with IV midazolam, sufentanil, etomiddate and cisatracurium besylate and maintained using combined intravenous-inhalational anesthesia, and patient-controlled intravenous analgesia (PCIA) was performed after operation.Pulmonary function indexes were measured before induction of anesthesia (T 0) and at 6, 12 and 24 h after removal of the tracheal tube (T 1-3). Blood gas analysis was performed at T 0, T 2 and T 3.The occurrence of high/low blood pressure, tachycardia/bradycardia, consumption of opioids, PACU stay time, pressing times of PCIA within 24 h after surgery, rescue analgesia, time of passing the first flatus, the first postoperative off-bed time, length of postoperative hospital stay, and 48 h quality of recovery-40 (QoR-40) were recorded.The occurrence of adverse reactions and nerve block-related complications were recorded within 48 h after operation. Results:Conversion to laparotomy during operation was found in 4 patients, changing the scope of resection in 2 patients, and a total of 50 patients were enrolled in this study.Compared with group G, the pressing times of PCIA was significantly reduced, the requirement for postoperative rescue analgesia was decreased, the intraoperative consumption of sufentanil and remifentanil was reduced, the incidence of intraoperative hypertension and tachycardia was decreased, the FEV1, FVC and PEFR were increased at T 2, 3, the 48 h QoR-40 score was increased, the time of passing the first flatus, the first postoperative off-bed time, and length of postoperative hospital stay were shortened, the incidence of nausea, agitation, somnolence, and hypoxemia was decreased ( P<0.05), and no significant change was found in the indicators of blood gas analysis at each time point in group TRG ( P>0.05). Nerve block-related complications were not found in group TRG. Conclusion:Compared with general anesthesia alone, TAP-RS block combined with general anesthesia is helpful in carrying out anesthetic model of low-consumption opioids and improving the quality of early postoperative recovery when used in the patients undergoing laparoscopic pancreaticoduodenectomy.

Objective:To explore the polymorphism of the uridine diphosphateglucuronosyl transferase 1A1 ( UGT1A1) gene in children of multiple nationalities with etiology-unknown neonatal hyperbilirubinemia in Qiubei County. Methods:Full-term neonates with unknown cause hyperbilirubinemia were collected.They were admitted to neonatal ward of Qiubei People′s Hospital from September 2017 to June 2018.All of them were performed UGT1A1 gene test. Results:A total of 100 neonates were enrolled in this study.Among them, 53 infants were Han, and others were minorities.Ten mutation sites of UGT1A1 gene were found.Five sites were never reported before and 4 sites could be pathogenic mutations.In addition, c.211G>A.was the most common genetic mutation, and 13 cases of homozygote and 32 cases of heterozygote were revealed by exome sequencing.The bilirubin levels of children with homozygote c. 211G>A were higher than those without the variation in this study and the differences were statistically significant ( t=2.621, P=0.008). The incidence of c. 211G>A mutation was similar between Han and minority nationalities.Among new-found mutations, c.1091C>CA heterozygous mutation was found in 19 children and in several nationalities, suggesting that this was a common UGT1A1 gene mutation in Qiubei County.Besides c. 211G>A and c. 1091C>CA were the most common variants.The incidence of c. 211G>A had no significant difference between Han and minority nationalities (χ 2=0.215, P=0.643). Neither had the incidence difference of c. 1091C>CA between Han and minority nationalities (χ 2=0.017, P=0.897). Conclusion:c. 211G>A and c. 1091C>CA mutations , which are distributed in both Han and minority nationalities, are common UGT1A1 mutations in Qiubei County.The distribution rate of c. 211G>A mutation is high in the population.The homozygous variation of c. 211G>A is associated with neonatal hyperbilirubinemia.
