[Abstract] Objective To evaluate the clinical and endoscopic manifestations of abdominal type allergic purpura in adult patients as the evidences in reaching early diagnosis. Methods The clinical and endoscopic manifestations of 32 patients with abdominal type allergic purpura were analyzed retrospectively. Re-SllltS All the patients complained of paroxysmal abdominal colic, 59. 4% patients complained of nausea and vomiting, 50% patients had hematochezia and haematemesis, the occult blood test was positive in all patients, and 25% patients had elevated level of amylase in the blood and urine. Purpura was found in 2-10 days after the presentation of abdominal pain. Endoscopy found hyperaemia, edema, bleeding spots, erosion and ulcer in gastroenterologic mucosa. Duodenal, ileum and caecum had more severe mucous lesions, but the esophageal mucosas in all patients were normal. The clinic and endoscopic misdiagnosis rates were 87.5% and 85.7% respectively. Glucocorticoids were the especially effective medicine in its treatment, while those agents for relieving spasm or antacids were ineffective. Conclusion Many scattered bleeding spots and snow flower-like ulcers on the gastrointestinal mucosa are the most important findings in adult abdominal type allergic purpura patients. Clinic manifestations of these patients are very severe abdominal colic in indefinite sites and merely with mild abdominal objective signs is the important characteristic feature.

BACKGROUND: Transplantation of microencapsulated rabbit Schwann cells in the rat spinal cord can relieve inflammatory reaction, promote spinal cord regeneration, but the precise mechanisms remain unclear. OBJECTIVE:To observe basic fibroblast growth factor (bFGF)expression and movements recovery following transplantation of microencapsulated rabbit Schwann cells in rat spinal cord. METHODS: The sciatic nerves taken out from rabbits wore digested with mixed enzyme and were made into Schwann cells suspension. Then we used air-jet method to make Schwann cells microcapsule. Using the same method, empty microcapsule was made. Sprague Dawiey rats were randomly divided into cell group, empty microcapsule group and microcapsule group. Conducted by hemisection injury of spinal cord,the rats in cell group,empty microcapsule group and microcapsule group were implanted with gelatin sponge with 10μL Schwann cells suspension, gelatin sponge with 10 μL empty microcapsule and 10 μL microencapsulated Schwann cells. Normal group was left intact. After operation, we observed hindlimb movements recovery in rats with the Basso, Beattie, and Bresnahan (BBB) scale. Meanwhile,a set of sections were stained immunohistochemically for bFGF expression, another set of sections wore stained for hematoxylin-eosin and Nissal. RESULTS AND CONCLUSION: After spinal cord injury, rat right hindlimb affected paralysis immediately. At 7, 14 and 28 daysfollowing transplantation,motor function in rat hindlimb was significantly recovered, and the BBB scores were significantly higher in microencapsulated schwenn cells than in cell and empty microcapsule group (P < 0.05 or P < 0.01). bFGF positive products were mainly distributed in cytoplasm of the spinal neuron and nucleus of neuroglical cell. The numbers of bFGF positive glial cells mainly appeared surrounding the spinal cord injured site on days 1, 3, 7 and rose to its peak on day 3 and began to appear in neuronal calls on day 14. The number of bFGF positiv cells in microcapsule group was significantly superior to that in cell group and empty microcapsule group. From then on, the bFGF expreSsion was significantly decreased in each group. These indicated that transplantation of microencapsulated Schwann cells can inhibit the immunological rejection after xenotransplantation, suppress inflammatory reaction, improve the expression of bFGF, increase hindlimb movements recovery and spinal cord regeneration after spinal cord injury.

Objective:To evaluate the efficacy and safety of pegylated liposomal doxorubicin (PLD) in CHOP regimen for un-treated elderly patients with advanced diffuse large B-cell lymphoma (DLBCL). Methods:In a prospective phase II study, we analyzed the feasibility of PLD-modified CHOP regimen in elderly patients with advanced stages of DLBCL. PLD was administered at 30 mg/m2 in combination with cyclophosphamide, vincristine, and prednisone at standard doses every 21 d for six cycles. CD20 positive patients were given option for rituximab treatment. Results:From November 2011 to March 2014, 30 patients with a median age of 70 years (range:63 to 80) were enrolled in this study. Up to 24 cases (80.0%) obtained an International Prognostic Index of≥3. The overall re-sponse rate was 86.7%, and the complete remission rate was 66.7%. With a median follow-up of 20.1 months, the 18-month overall and progression-free survival rates were 82.4%and 70.1%, respectively. The main toxicity was neutropenia, reaching grades 3 to 4 in the 24 cases (80.0%). No significant changes existed in patients' left ventricular ejection fraction and serum troponin-T during the study. Four patients (13.3%) showed asymptomatic abnormal changes in electrocardiogram after PLD infusion. Conclusion:CHOP regimen with PLD is an effective alternative for the treatment of DLBCL in elderly patients, exhibiting an acceptable toxicity.

To promote quality of the whole nursing,build harmonious relation of nurse and patient is basement.Nurse how to make language art utilize at the interflow of nurse and patient,to promote understanding and sustain between nurse and patient,improve cure,nursing effect,reduce contradictory of nurse and patient is the key of building harmonious relation of nurse and patient.

Comparing the patients with type 2 diabetes and the control and using the animal models,the researchers have found some disease related proteins and the marks for disease detection.They have set some new detection methods and give us a special view into type 2 diabetes.We do some primary discussions about recent studies and future development directions in the proteomics study of type 2 diabetes in this article.

Abstract: Objective To explore the correlation between lung function in patients with chronic obstructive pulmonary disease (COPD) and tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels in exhaled breath condensate (EBC), and to provide a convenient methodological basis for the diagnosis and treatment of COPD and the determination of its efficacy. Methods A total of 81 COPD patients and 40 healthy controls were selected from the respiratory department of the Fourth Affiliated Hospital of Guangzhou Medical University from August 2020 to February 2022 as the research subjects. The COPD patients were divided into 41 cases in the acute exacerbation group and 40 cases in the remission group according to their status. All participants underwent lung function detection, venous blood and EBC collection, and the levels of TNF-α and IL-1β in EBC and venous blood were analyzed by enzyme-linked immunosorbent assay (ELISA), and correlation analysis was performed by Pearson correlation analysis method. Results The levels of TNF-α and IL-1β in EBC of in the acute exacerbation group, the healthy control group, the remission group were (5.16±0.18) pg/μL and (7.75±0.27) pg/μL, (2.66±0.31) pg/μL and (2.41±0.24） pg/μL, (3.61±0.29) pg/μL and (3.17±0.38) pg/μL, respectively. Compared with the healthy control group, the levels of TNF-α and IL-1β in EBC in the COPD acute exacerbation group were significantly higher than those in the healthy control group and the COPD remission group (F=9.451, 8.217, P<0.001). Serum tests were consistent with this result. Correlation analysis showed that the levels of TNF-α and IL-1β in EBC were significantly positively correlated with the level of serum inflammation levels (P<0.001), while significantly negatively correlated with lung function (P<0.001).  Conclusions TNF-α and IL-1β in EBC are potential biomarkers of inflammation in patients with COPD, and their detection can be used to effectively assess lung function in patients with COPD.
