OBJECTIVE: To observe the clinical effect of perforated bovine amnion combined with recombinant bovine basic fibroblast growth factor (rb-bFGF) on degree Ⅱ burn wounds.METHODS: A total of 43 patients with small and medium-size thermal burn were collected, and the area of testing wound was 1% -2%. The wounds with the same nature were divided into three groups: perforated bovine amnion (treatment group), bovine amnion (control 1 group), and vaseline gauze dressing (control 2 group). All the three groups combined with rb-bFGF. RESULTS: Compared with control 1 group (P < 0.01) and control 2 group (P < 0.05), the treatment group could obviously decrease the healing time of deep degree Ⅱ burn wounds. For superficial degree Ⅱ burn wounds, compared with the control 2 group, the treatment group could also decrease the healing time; however, there was no significant difference between treatment group and control 1 group (P > 0.05). Dressing was not changed frequently, and the pain was relieved. Rash or other adverse effects were not detected in the three groups.CONCLUSION: The combination of perforated bovine amnion and rb-bFGF can obviously promote the healing of burn wounds.

Objective To assess the effect of low-dose cytarabine and aclarubicin in combination with gran-ulocyte colony-stimulating factor (G-CSF) protocol (CAG) in patients with acute myeloid leukemia (AML),and to understand the potential factors affecting the outcome of CAG induction therapy, therefore to find the optimum pa-tients for CAG therapy. Methods Twenty-one AML patients were enrolled in the current study. All patients were treated with CAG regimen including cytarabine (10 mg/m~2, subcutaneously, every 12 h, days 1 - 14), lacinomycin (5～7 mg/m~2,intravenously,every day, days 1 -8) ,and G-CSF (200 μg/m~2,subcutaneously, every day,12 h be-fore Ara-C was given) priming. Results The overall complete remission (CR) rate of the 21 AML patients was 66.7% (14/21). The CR rates was 87.5% (7/8) in patients older than 60 yrs,60.0% (9/15) in the refractory or relapsed patients,83.3% (5/6) in the MDS transformed AML patients. The CR rates for patients with hyperprolif-erative BM and median to poor proliferative BM were 33.3% and 91.7% ,respectively(P =0.009). The median o-verall survival (OS) time of the 21 AML patients was 450 days. Two-year survival rate estimated by Kaplan-Meier Method was 30.6%. The overall median disease free survival (DFS) was 165 days. The median OS time for those refractory or relapsed was 435 days. The median OS time for those with poor cytogenetic state or standard or good cytogenetic state was 140 days and 620 days, respectively (P = 0.001). The median OS time for patients with hyperproliferative BM and median to poor proliferative BM was 321 days and 620 days, respectively (P = 0.05). The median recovery time of granulocytes above 1.0×10~9/L was 8 days. The median duration of fever was 3.5 days. The rate of infections exceeding WHO grade Ⅱ was 42.9%. No early death occurred. Conclusions The CAG induction therapy may have a higher CR rate in patients with refractory or relapsed AML, elderly AML and secondary AML from MDS transformation, and extend the median overall survival time in refractory or relapsed patients. CAG therapy can not improve the outcome of patients whose BM was in high grade proliferation state or whose cytogenetic state was poor. CAG therapy can shorten the duration of agranulocytosis and decrease the inci-dence of serious infection. Therefore, CAG therapy is worth recommending to patients who can not endure the rou-tine intensive chemotherapy.

Objective To explore an improving primary culture method of human pituitary adenoma cells.Methods Thirty-six pituitary adenoma specimens,collected from excision and conformed by pathology in our hospital from November 2014 to June 2015,were used.Based on the former experience from papers and ourselves,our primary culture methods of several different kinds of human pituitary adenomas were improved.Purification and passage culture of cells were performed in the following experiments.CCK-8 assay was used to detect the multiplication capacity of pituitary adenoma cells;immunofluorescent staining and Western blotting were used to observe the cytokeratin and vimentin protein expressions.Results By using the improve culture methods,tumor cells proliferated in suspension with good status and had the tendency of aggregation in culture medium.The proliferation test showed that the tumor cells enjoyed proliferation ability in vitro;tumor cells could pass over five generations.The growth curve of pituitary adenoma cells showed S pattern.Immunofluorescent staining and Western blotting indicated negative cytokeratin and vimentin protein expressions,showing that the cells were from epithelium.Conclusion Each type of pituitary adenoma cells has characteristics of suspended growth and tendency of gathering by using this improved method.

Objective To systematically evaluate the risk factors for new-onset atrial fibrillation after off-pump coronary artery bypass grafting (OPCABG). Methods PubMed, EMbase, The Cochrane Library, CNKI, Wanfang, VIP, SinoMed were searched to collect published literature on risk factors for new-onset atrial fibrillation after OPCABG from inception to September 2022. Two authors independently screened, extracted data and evaluated the quality. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies, and Stata 12.0 and RevMan 5.4 softwares were used for meta-analysis. Results A total of 18 researches were included, including 6 354 patients of OPCABG. The NOS scores of the included studies were 6-8 points. Meta-analysis showed that age [MD=2.56, 95%CI (1.61, 3.52), P<0.001], hypertension [OR=1.77, 95%CI (1.18, 2.66), P<0.001], EuroSCORE Ⅱ score [MD=0.70, 95%CI (0.34, 1.06), P<0.001], frequent atrial premature beats or atrial tachycardia [OR=3.77, 95%CI (2.13, 6.68), P<0.001], left atrium diameter (LAD) [MD=1.64, 95%CI (0.26, 3.03), P=0.010], left ventricular ejection fraction (LVEF) [MD=−1.84, 95%CI (−2.85, −0.83), P<0.001], right coronary stenosis [OR=2.49, 95%CI (1.29, 4.81), P=0.006], three-vessel coronary artery lesions [OR=0.73, 95%CI (0.54, 0.97), P=0.030], not using β blockers [OR=0.81, 95%CI (0.69, 0.96), P=0.010], operation time [MD=10.13, 95%CI (8.15, 12.10), P<0.001], duration of mechanical ventilation [OR=2.85, 95%CI (1.79, 3.91), P<0.001] were risk factors for new-onset atrial fibrillation after OPCABG. Conclusion Advanced age, hypertension, high EuroSCOREⅡ score, frequent atrial premature beats or atrial tachycardia, increased LAD, decreased LVEF, right coronary stenosis, three-vessel coronary artery lesions, not using β blockers, prolonged operation time and mechanical ventilation are risk factors for new-onset atrial fibrillation after OPCABG. Due to factors such as the methodology, content and quality of the included literature, the conclusion of this study need to be supported by more high-quality studies.
