ABSTRACT
Objective:To explore the early application effect of the bedside sitting respiratory training in patients with respiratory failure and noninvasive positive pressure ventilation of the acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:A total of 102 patients with respiratory failure and noninvasive positive pressure ventilation of the AECOPD treated in Shanghai Public Health Clinical Center from June 2018 to December 2019 were selected and divided into the control group and the research group by random digits table method with 51 cases in each group. The control group was given the conventional treatment and nursing measures; and the research group was given the bedside sitting respiratory training. Pulmonary functional and blood -gas analysis parameters, clinical outcome of patients, etc. before and after the intervention between the two groups were compared. Results:After the intervention, the forced expiratory volume in one second (FEV 1), forced vital capacity(FVC), FEV 1/FVC were (1.79±0.22) L, (3.09±0.28) L, (62.16±5.94)% in the research group, and (1.43±0.18) L, (2.66±0.23) L, (53.48±5.31)% in the control group, the differences were statistically significant(t values were 8.36, 8.00, 7.19, P<0.01). Arterial partial pressure of carbon dioxide (PaCO 2) and arterial partial pressure of oxygen (PaO 2) in blood gas analysis were (51.14±3.79) mmHg(1 mmHg=0.133 kPa), (71.07±5.49) mmHg in the research group, and (57.52±3.86) mmHg, (65.62±5.27) mmHg in the control group, the differences were statistically significant ( t values were -7.78, 4.72, P<0.01). The non-invasive positive pressure ventilation time, hospital stays were (7.41±1.76) d, (11.27±2.41) d in the research group, and (9.79±2.11) d, (15.46±3.12) d in the control group, the differences were statistically significant ( t values were -5.71, -6.70, P<0.01). The incidence of adverse events was 3 cases in the research group, 1 case in the control group, the difference was no statistically significant ( P>0.05). Conclusions:The application of the bedside sitting respiratory training in patients with respiratory failure and noninvasive positive pressure ventilation of the AECOPD can effectively improve the pulmonary physiological function, shorten the noninvasive positive pressure ventilation time and hospitalization time, which has clinical application value.
ABSTRACT
Objective:To explore the efficacy and adverse reaction of TOMOX regimen combined with three dimensional conformal radiotherapy in the treatment of middle and advanced esophageal cancer. Methods:51 cases of hospitalized patients with esophageal cancer were selected from January 2013 to December 2015 in our hospital who were divided into observation group (n=27) and control group (n=24) by random number table method. The control group was treated with three dimensional conformal radiotherapy, and the observation group was added with the TOMOX scheme based on the control group. Compare the efficacy of the two groups, the control period, the survival period, the toxicity and side effects.Results: The rate of complete response(CR)and partial response (PR) in the observation group was significantly higher than that in the control group, the difference was statistically significant (P0.05). The rate of acute esophagitis in the observation group group was higher than that in the control group, the difference was statistically significant (P<0.05).Conclusion: TOMOX combined with three-dimensional conformal radiation therapy can effectively improve the short-term efficacy and long-term survival rate, reduce adverse reactions.
ABSTRACT
Objective To assess the safety and efficacy of preoperative intensity-modulated radiotherapy(IMRT) with oral capecitabine in patients with locally advanced mid-low rectal cancer using a simultaneous integrated boost (SIB) of tomotherapy.Methods Total 16 patients with resectable locally advanced mid-low rectal cancer (patients with T3 to T4 and/or N ± rectal cancer) were enroll in current study.Patients were received IMRT to 2 dose levels simultaneously (55 and 47.5 Gy in 25 fractions) with concurrent capecitabine 825 mg/m2 twice daily,5 days/week.Total mesorectal excision was performed at 8 to 9 week after the completion of chemoradiation.The primary end point included side effect,the rate of sphinctersparing,postoperative complication and pathological complete response rate (pCR) were observed.Side effects were scored using the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0.Results All patients were received chemoradiotion therapy without any break.Tomotherapy showed superiority with respect to target coverage,homogeneity and conformality.Two patients refused to perform radical surgery because of almost complete primary tumor regression and complete symptom relief after neoadjuvant therapy.Fourteen patients underwent surgical resection and 11 patients (78.6％) underwent sphincter-sparing lower anterior resection.Four patients(28.6％) had a pathological complete response.The incidence of grade 1-2 hematologic,gastro-intestinal toxicities were 62.5％ (10/16) and 18.8％ (3/16).The incidence of grade 3 skin toxicities were 68.8％(10/16).Grade Ⅳ side effect was not observed.Surgical complications (incisional infection on thirteen after surgery) were observed in 1 patient.Conclusion Preoperative simultaneous integrated boost of tomotherapy with concurrent oral capecitabine is safe and well tolerated in patients with a promising local control.However,a larger number of patients and a long follow-up are required to assess its potential superiority.

ABSTRACT
Objective:To introduce the fabrication of lead eyeshade and its use in the radiotherapy of both malignant and benign eye tumors and observe the preliminary clinical effect. Methods:To lead sheet with thickness of 2.5-3mm was fabricated into spherical eyeshade and erythromycin Eye Ointment was smeared onto it. Results:According to EORTC criteria, the first level side effect was occasional and mild pain and drying of the eye. The second level was intermittent and tolerable pain and drying of the eye. The third level was constant and intense pain and drying of the eye and the fourth level was incurable and intolerable and drying of the eye. Conclusion:It was shown that the use of lead eyeshade can not only ensure the efficacy of radiotherapy, but also reduce the incidence of radiation injury of surrounding normal tissues. The method used for making of lead eyeshade is effective and easy to grasp.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the anaphylaxis and hemocytolysis of 6 kinds of tween-80 injection from different source.</p><p><b>METHOD</b>The Hartley albinism guinea pig was used to carry on the active systematic anaphylaxis (ASA) and the passive cutaneous anaphylaxis (PCA). The in vitro hemolytic experiment and the hemocytolysis was observed by means of spectrophotometry on the domestic rabbit.</p><p><b>RESULT</b>The result of ASA and PLA of 6 kinds of tween-80 injection from different source assumed the negative. In observation time, the temolysis rate of 3 kinds of tween-80 injection are more than 5%, while the others are also more than 5% only in the highly concentrated test tube.</p><p><b>CONCLUSION</b>Six kinds of tween-80 injection from different source have not caused the immune-mediated anaphylaxis, but it may have hematolysis tendency on intravenous injection. The hemocytolysis of tween-80 may not be entirely caused by the impurities. It is worthy of further study that the physical and chemical properties of the product itself and the undeserved concentration is doubtful whether there is also some internal relations with the generation of hemolytic.</p>

OBJECTIVE To investigate and analyze the reasons of nosocomial infection(NI) in patients in intensive care unit( ICU),to find effective countermeasures for preventing NI and reducing the incidence rate of NI in ICU,and to enhance the management of ICU.METHODS All data of patients who suffered MRSA in ICU from Dec 2005 to Feb 2006,were analyzed by prospective monitoring and retrospective studies.RESULTS The nine patients were with lower respiratory tract.All were infected by the same MRSA.The same MRSA strain was found from hand,mouth and nose among the treating doctor and nurses based on the sample-analysis.CONCLUSIONS The incidence rate of NI in ICU is much higher than that in other departments.Risk factors depend on the severity of underlying diseases,invasive procedure,the quality of disinfection and sterilization,the incorrect use of the antibiotic,and patients′ immunity status especially among elderly.The key way to reduce incidence rate of NI is to take comprehensive measures and strengthen the antibiotic management.
