Objective To study the effect of preemptive analgesina of morphine injected to subarachnoid space on postoperative epidural analgesia with morphine. Methods Sixty ASA Ⅰ-Ⅱ patients were randomly divided into two groups. All patinents received combination spinal-epidural anesthesia(CSEA). In experimenta group (n=30), 0 5% bupivacaine 2ml and morphine 0 5mg were injected into the subarachnoid space of the patients for CSEA, and morphine 2 8mg was used for postoperative epidural analgesia. In control group (n=30),0 5% bupivacaine 2ml was injected into the subarachnoid space of the patients for CSEA, and morphine 3 3mg was used for postoperative epidural analgesia. The numerical rating score (NRS) and Ramsay sedation scores were performed after operation. The postoperative analgesic duration and frequency of side effect were recorded. Rusult NRS was significantly less and postoperative analgesic duration was obviously longer in experimental group compared with control group. Ramsay sedation scores and the frequency of side effect significantly increased in the experimental group compared with the control group. But the shaking frequency in experimental group was significantly less than that in the control group. Conclusions Preemtive analgesia of morphine injected to subarachnoid space could improve postoperative epidural analgesia with morphine and increase analgesia time. But it had more side effects.

Objective:To investigate the adherence of patients with chronic airway disease with inhalation therapy and to explore the influencing factors.Methods:A total of 180 outpatients with chronic airway disease were selected by convenient sampling. The general information, adherence of inhalation therapyquestionnaire, asthma knowledge questionnaire, chronic obstructive pulmonary disease (COPD) health literacy questionnaire (COPD-Q) were used to evaluate the general information, adherence of inhalation therapy and disease knowledge level of the patients. The severity of the disease was evaluated by asthma control test (ACT) score and COPD assessment test (CAT) score. ANOVA and t-test were used to analyze the adherence of patients with chronic airway disease, and multivariate linear regression was used to analyze the adherence. Results:The adherence score of asthma patients was 89.74 ± 7.27 and the adherence score of COPD patients was 86.80 ± 9.16, which were in the middle level. The risk factors of non-adherence of inhalation therapy were retirement, living alone and smoking. The effect of inhaled treatment time on the adherence of inhaled therapy is not linear, and the turning point of adherence decline occurs one year after the patients received inhaled therapy. The results of multiple linear regression showed that the effect of course and employment on the adherence of inhalation therapy was statistically significant.Conclusions:The adherence of chronic airway disease patients with inhalation therapy is not ideal, especially for the patients with long course, smoking, retirement and living alone, the medical staff should pay more attention, take appropriate intervention measures to improve the adherence of inhalation therapy.

Objective To evaluate the necessity and feasibility of low-dose dual-source CT coronary angiography imaging in the evaluation of high body mass index (BMI) patients. Methods Sixty patients with BMI≥28 kg/m2 and heart rate 65-90 beats/min were selected, and they were divided into prospective electrocardiography gated scanning group and retrospective electrocardiography gated scanning group by random digits table method with 30 cases each. The image quality, CT dose weighing index (CTDI) and dose length product (DLP) were compared between 2 groups. Results There was no statistical difference in the score of coronary image quality between retrospective electrocardiography gated scanning group and prospective electrocardiography gated scanning group:(3.47±0.61) scores vs. (3.18±0.94) scores, P>0.05. The CTDI and DLP in prospective electrocardiography gated scanning were significantly lower than those that in retrospective electrocardiography gated scanning: (32.44 ±10.18) mGy vs. (45.86 ±15.34) mGy and (458.00±95.27) mGy/cm vs. (532.15±154.43) mGy/cm, and there were statistical differences (P<0.05). Conclusion For high BMI patients, different low-dose dual-source CT scanning, especially prospective electrocardiography gated scanning, can guarantee image quality and reduce the radiation dose and the radiation damage at the same time.

Objective To evaluate the efficacy and safety of endoscopic submucosal excavation (ESE) and submucosal tunneling endoscopic resection (STER) for gastroesophageal junction (GEJ)submucosal tumors (SMTs) originating from the muscularis propria(MP) layer.Methods Clinical data of sixty-one patients with GEJ SMTs originating from the MP layer who were treated with ESE(ESE group,n=39) or STER(STER group,n=22) between January 2013 and December 2015 in Changhai Hospital were retrospectively analyzed.Outcomes and complications in the two groups were compared.Results Single lesion in 61 patients were all resected by therapeutic endoscopy successfully.Operation time in the STER group was shorter than that of the ESE group(47.27±20.89 min VS 66.56±40.07 min,P＜0.05).There was no significant difference in number of hemostatic clips between the two groups[7.10±5.57 VS 8.00± 1.88,P＞0.05].Hospitalization time of STER group was shorter than that of the ESE group [3.0(1.25) d VS 4.0 (1.00) d,P＜0.05].One patient developed delayed hemorrhage in ESE group,while no other complications occurred in either group.The wound healed in both groups under gastroscopy,and no residual or recurrent tumors were detected during the follow-up period.Conclusion Both STER and ESE can be used for GEJ SMTs originating from the MP layer,but STER is more safe and efficient.

Multiple sclerosis ( MS) is an autoimmune disease of the central nervous system ( CNS) characterized by demyelination and inflammation lesions.MS predominantly affects young adults with a high incidence of disability. However, the exact pathogenesis of MS is still not clear.Studies found that microglia polarization tending to pro-inflammatory M1-like state during the onset of MS, causing the M1/M2 ratio imbalance, forming pro-inflammatory microenvironment state, and which further leading to nervous tissue damage ultimately.Microglia polarization may be considered as the initiator of pathologic alterations by releasing pro-inflammatory cytokines and secondarily trigger the initial microglia response.Given the pivotal role of imbalanced microglia polarization in MS initiation, a critical review of microglia polarization is presented here, in order to elucidate the pathogenesis of MS and highlight the noteworthy candidate therapeutic targets for clinic treatment.

Objective To explore the physical/chemical properties and effect of photodynamic therapy (PDT) of iminodiacetic acid modified tetraphenylporphyrin on mice bearing H22 liver cancer.Methods The UV absorbance spectrum,singlet oxygen yield and lipid-water partition coefficient were measured by UV spectrophotometry.Mice bearing H22 liver cancer as animal model were divided into control group (no drug,no light),light treated group (no drug,only light),drug treated group (only drug,no light),experimental once group (with drug and light,once) and experimental twice group (with drug and light,twice,PDT twice).Tumor inhibition rate and index of liver,spleen,lung,thymus of the mice were calculated to evaluate the antitumor activity of iminodiacetic acid modified tetraphenyl porphyrin-PDT.Results The iminodiacetic acid modified tetraphenylporphyrin had absorption at 650 nm,while its singlet oxygen yield and lipid-water partition coefficient were 2.30 and 0.52,respectively.No antitumor effect on mice bearing H22liver cancer for light treated group and drug treated group respectively.However,significant antitumor effect (P＜0.001)was found at experimental group.The maximum tumor inhibition rate could be 95.15％ for PDT twice group.No significant differences were observed on weight gain and liver,lung,spleen,thymus index in each group.Conclusion Iminodiacetic acid modified tetraphenylporphyrin with high singlet oxygen yield,low toxicity and significant in vivo anti-tumor activity,is suitable to be developed as an anti-tumor drug candidate for photodynamic therapy.

This paper develops an intelligent NO delivery system cooperating with the ventilator to make NO inhaled safely, reliably, conveniently and economically, which is based on correlation between the parameter setup of the ventilator and the concentration of NO. The circuit control system consists of a mass flow controller and a CPU mainly. A mixing unit is designed to mix NO with the gas from the ventilator uniformly. Clinical experiments show that the NO from the intelligent delivery system can decrease PH and increase SaO2 with the concentration of generated NO2 less than 5ppm.
