Objective:To summarize the establishment and management experience of extracorporeal membrane oxygenation (ECMO) rapid response team, and explore a more efficient rescue mode.Methods:From January 2015 to September 2020, 85 patients treated with ECMO in Affiliated Hospital of Qingdao University were selected as the research objects. Thirty-eight patients treated with conventional ECMO from January 2015 to December 2019 were selected as the control group, and 47 patients treated with ECMO rapid response team from January 2020 to September 2020 were selected as the experimental group. The differences in team preparation time, catheterization time, treatment success rate, incidence of complications and equipment failure frequency between the two groups were compared.Results:There were no significant differences in gender, age or disease types between the two groups. The team preparation time and catheterization time of the experimental group were significantly shorter than those of the control group [team preparation time (minutes): 31.79±6.10 vs. 67.16±30.49, catheterization time (minutes): 40.62±7.13 vs. 84.89±19.29], and the incidence of complications was significantly lower than that of the control group [4.3% (2/47) vs. 21.1% (8/38)], and the differences were statistically significant (all P < 0.05). Conclusion:ECMO rapid response team can shorten the rescue preparation time, reduce the occurrence of complications, improve the team treatment efficiency, and provide ideas for emergency and critical patients.

The patients with dedifferentiated thyroid carcinoma were induced by all-trans retinoic acid (ATRA). The treatment was effective in 5 patients (5/9,55.6%), and 5 patients were benefited from following 131 I treatment(5/8, 62.5% ). Three patients(3/12,25.0% ) quitted because of neurological side-effects. It is efficacious to apply ATRA to induce dedifferentiated thyroid carcinoma and improve radio-iodine uptake and acquire benefit for patients, but clinic application of ATRA must be cautious.

The medium and process parameters were optimized in batchaminoglycoside antibiotic JI-20A fennentation. The optimal medium consists mainly of comstarch 60g/L, peanut meal 30g/L, com slurry 8g/L, maltose 10g/L, inorganic compound and amylase moderate , methionin 1g/L and cobalt chloride 6?g/mL. It was significant to adjust medium pH after autoclaving and oxygenate the fennentation medium for the cell growth and JI-20A product.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P＜0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P＜0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P＜0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.

To make a preliminary study on the mechanism of Coptidis Rhizoma(CR) and Rehmanniae Radix(RR) before and after the combined administration in treating type II diabetes mellitus. The type I diabetes animal model in rats was established by fat emulsion and intraperitoneal injection with streptozotocin, in order to compare the hpyerglycemic and hypolipidemic effects of CR, RR and their combined administration of different ratio. The urinary metabolic profiling in rats of Coptidis Rhizoma and Rehmanniae Radix before and after the combined administration was analyzed by using the gas chromatography-mass spectrometry. The differences among groups in metabolome were analyzed by the principal component analysis (PCA). The biochemical index results indicated that both CR and RR before and after the combined administration could lower high blood glucose, hypertriglyceride and high cholesterol. According to the analytical results of PCA of the rats' urine samples, the CR group was the most close to the normal group, with no significant difference in CR and RR group of different combination ratios. Twelve differentiated metabolites were identified to be related to type II diabetes. Compared with the normal group, the CR-treated group showed significant increase in seven differentiated metabolites. Among CR and RR drugs with different combination ratios, CR played a major role and thus acted as the monarch drug. Whereas RR served as the ministerial drug and assisted CR to show the efficacy. This study laid a foundation for the explanation of the combination mechanism of traditional Chinese medicines.

AIM: To analyze the effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
METHODS: Fifty patients (50 eyes) with neovascular glaucoma collected from January 2013 to August 2015 in our hospital were treated by trabeculectomy combined with intraoperative application of mitomycin C. Single factor and multi factor variables analysis were used for effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
RESULTS: By results of single factor variable analysis,< 50 years old, preoperative intraocular pressure ( IOP) was ≥45mmHg and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and gender, proliferative diabetic retinopathy and previous cataract surgery and prior photocoagulation were not the risk factors for failure (P>0. 05 ). By multivariate analysis, < 50 years old and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and preoperative IOP≥45mmHg was not a risk factor (P>0.05). CONCLUSION: For patients < 50 years old with neovascular glaucoma, should be careful on the selection of surgical treatment. For high- risk patients, we should strengthen the monitoring and give timely intervention, which are helpful to improve the prognosis.

Objective To analyze the monitoring results of human and animal plague in Zhangye city from 1982 to 2011,and further explore the prevention and control policies and measures to control the spread of the disease.Methods The trends of human and animal plague were studied by retrospective survey in Zhangye city.Information of animal and human plague epidemic and prevention and control measures were collcoted and assessed with epidemiology methods,and the density of rodents,the rodents infected with flea,flea index and other indicators were calculated.Results 1982-2011,there were 6 cases of human plague incidence of 6 cases,of which 2 cases cured,4 cases died,the mortality rate was 67％; detection of Yersinia pestis from the captured 5167 animals was 93 strains from 1982 to 2011,the detection rate was 1.80％; 29 840 various vector insects were collected from the body surface of the 5167 animals captured,21 206 hole dries,and three marmot dens.A total of 7050 groups of Marmota parasites and hole stem fleas were inspected,52 strains of Yersinia pestis were isolated,and the average detection rate was 0.74％; 3912 marmot serums were detected,178 were positive,and the positive rate was 4.55％.Conclusions The prevention and control of plague is still very grim in Zhangye city.It is recommended to take publicity,education and active surveillance measures in the future to deal with emergencies and other.

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2), (+)-reticuline (3), (+)-laurotetanine (4), (+)-isoboldine (5), (+)-N-methyl-laurotetanine (6), and berberine (7), respectively. Among them, 7 was isolated from the genus for the first time. The evaluation of these compounds showed weak anti-inflammatory activity against NO production in RAW 267.4 and BV-2 cells.
