Objective To observe the effects of blood pressure by intravenous infusion of different doses ofoxytocin in cesarean section.Methods Sixty full-term pregnant women undergoing cesarean section with continuous epidural anesthesia were divided into three groups by random digits table method with 20 cases each:group A,B and C.Three groups were injected 10 U oxytocin in uterine muscle after infant delivery.Group A,B and C received 5,10 and 20 U oxytocin (sodium lactate ringer,500 ml) continuous intravenous infusion at the speed of 10 ml/min.If happened uterine contractions bad,they were sublingual administering 0.2 mg misoprostol.If happened severe hypotension,they were intravenous injected 5 mg ephedrine.The change of mean arterial pressure (MAP) and heat rate before anesthesia (T0),after fetal childbirth (T1),5 m in (T2),10 min (T3),30 min (T4) after infusion of oxytocin and the dosage of ephedrine and misoprostol were recorded.Results There were no significant differences in MAP and heart rate at every time point between group A and B (P＞ 0.05).MAP decreased and heart rate increased in group C at T2,T3 compared with those in group A and B,and there were significant differences (P＜ 0.05).The number of cases of sublingual misoprostol were increased in group A (7 cases) compared with that in group B (2 cases) and group C(1 case).The 8 patients injected ephedrine in group C were more than group A(1 case) and group B (3 cases).Conclusion Cesarean section after the delivery of the fetus in the uterus muscle injection of oxytocin 10 U,after 10 U of oxytocin added 500 ml sodium lactate ringer injection at the speed of 10 ml/min intravenous infusion has little effect on the blood pressure and heart rate,and has good uterine contractions.

Objective To explore the clinical effect of radio-frequency ablation in the treatment of advanced pancreatic cancer.Methods Retrospectively analyzed the clinical data of 28 cases of radio-frequency ablation in the treatment of advanced pancreatic cance between January 2008 and December 2012 in 304 hospital.And choosed made 140 cases patients who only underwent the conservative treatment as the control group at the same period.Then compared the data of two groups patients.Results The mean tumor diameter was (4.8 ± 1.6) cm.The average radio-frequency time was (17.7 ± 4.3) minutes.There was no patient occurred of pancreatic fistula or postoperative bleeding,and no patient dead.Peri-operation pain relief rate was 88.9％.Twenty-three patients were followed up,and the follow up rate was 82.1％.The patients' survival rate who underwent radio-frequency ablation of 1 month,6 months and 1 year were 95.7％,65.2％ and 38.2％.The average survival time was (14.6 ± 2.2) months.And the data was significantly higher than that of the control group patients (97.4％,45.3％,19.1％,P =0.0306).Conclusions The radio-frequency ablation was one of an effective treatment method for the advanced pancreatic cancer patients.It can prolong the survival time of pancreatic cancer patients and alleviate the patient's pain.

Objective:To investigate the risk factors for anterior circulation and posterior circulation symptomatic intracranial atherosclerotic stenosis (sICAS).Methods:The clinical data of patients admitted to Hebei General Hospital for ischemic stroke or transient ischemic attack (TIA) and diagnosed with sICAS by digital subtraction angiography from May 2019 to May 2020 were retrospectively included. The patients were divided into anterior circulation group and posterior circulation group according to the stenosis sites, and the distribution of sICAS and its risk factors were analyzed.Results:A total of 134 patients with sICAS were enrolled, including 82 males (61.2%) and 52 females (38.8%). Their age was 60.28±11.46 years; 115 (85.8%) had ischemic stroke and 19 (14.2%) had TIA. There were 92 patients (68.7%) in the anterior circulation group and 42 (31.3%) in the posterior circulation group. Body mass index (BMI), systolic and diastolic blood pressure levels, as well as the proportion of patients with hypertension, diabetes, smoking and drinking in the posterior circulation group were significantly higher than those in the anterior circulation group (all P<0.05). Multivariate logistic regression analysis showed that higher BMI (odds ratio [ OR] 1.191, 95% confidence interval [ CI] 1.029-1.379; P=0.019), hypertension ( OR 4.073, 95% CI 1.135-14.616; P=0.031) and diabetes ( OR 2.783, 95% CI 1.149-6.738; P=0.023) were independently correlated with the posterior circulation sICAS. Conclusions:Compared with anterior circulation, high BMI, hypertension and diabetes are the independent risk factors for posterior circulation sICAS.

Abstract: Objective　To explore the early diagnostic value of peripheral blood peroxisome proliferator-activated receptor γ (PPARγ) combined with γ-interferon (IFN-γ) release assay (IGRA) in the diagnosis of pulmonary tuberculosis in patients with end-stage renal disease (ESRD), and to provide reference for clinical diagnosis and treatment. Methods　From January 2019 to December 2021, 70 ESRD patients with suspicious symptoms of pulmonary tuberculosis were treated at Hebei Chest Hospital were selected as the research objects. According to the examination results, they were divided into ESRD group (40 cases) and ESRD complicated by pulmonary tuberculosis (40 cases, comorbidity group). In addition, 40 cases with pulmonary tuberculosis were used as the PTB group. All three groups of patients underwent IGRA test, and the peripheral blood PPARγ level was detected by enzyme-linked immunosorbent assay, and the diagnostic value of PPARγ combined with IGRA test for ESRD patients with pulmonary tuberculosis was explored. Results The expression level of PPARγ and IFN-γ content in the PTB group and the comorbidity group were obviously higher than those in the ESRD group (P<0.05), while the differences in PPARγ expression level and IFN-γ content between the PTB and comorbidity groups were not statistically significant (P>0.05). The ROC curve showed that the areas under the curve (AUC) of PPARγ and IGRA in the diagnosis of end-stage renal disease combined with tuberculosis were 0.823 (95%CI: 0.722-0.925) and 0.773 (95%CI: 0.662-0.883), respectively, and the AUC of combined detection was 0.928 (95%CI: 0.871-0.984), which was better than that of PPARγ and IGRA alone (Z/P=2.057/0.039, 2.843/0.005). The Kappa values of serum PPARγ and IGRA test compared with the clinical gold standard results in the diagnosis of ESRD complicated with pulmonary tuberculosis were 0.557 and 0.444 (P<0.05). The combined screening of ESRD with pulmonary tuberculosis was consistent with the clinical gold standard (Kappa=0.661, P<0.05). Among the 30 ESRD patients complicated with pulmonary tuberculosis, the sensitivity of PPARγ combined with IGRA test in diagnosis of ESRD complicated with pulmonary tuberculosis was 93.33% (28/30), which was higher than 70.00% (21/30) of PPARγ and 66.67% (20/30) of IGRA test alone (P<0.05). Conclusions Peripheral blood PPARγ and IGRA tests have certain diagnostic value for ESRD complicated with tuberculosis, and the combined detection of the two can improve the sensitivity and reduce the rate of missed diagnosis, which is worthy of clinical promotion.

Objective To explore the timing of local anesthesia in ultrasound-guided modified Seldinger technique PICC puncture, so as to provide theoretical basis for formulating unified operating standards in clinic. Methods Totals of 128 patients with PICC after operation were randomly divided into pre-anesthesia group and post-anesthesia group (64 cases in each group).In pre-anesthesia group, 0.2 ml 2%lidocaine was injected in the puncture point before puncturing; in post-anesthesia group, 0.2 ml 2% lidocaine was injected after puncturing.Body pain score in the process of puncturing and times of puncturing were compared between the two groups.Results The body pain score in pre-anesthesia group was (1.64 ±1.58),and (1.64 ±1.21)in post-anesthesia group, the difference was not statistically significant (t=0.00,P>0.05).The times of puncturing in pre-anesthesia group was (1.59 ±1.35), which higher than (1.18 ±0.50) in post-anesthesia group, and the difference was statistically significant (t=2.20,P<0.05).In pre-anesthesia group, the distance from local anesthesia point to the actual piercing point was positively related to pain score (r =0.319,P <0.05). Conclusions The pain were no different caused by local anesthesia before and after piercing, but less piercing times in condition of anesthesia after putting thread in, which can improve the success rate of puncture.
