OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.

METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.

RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).

CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.

After testing the resistance of Streptomycin to the strain NS-41-80 which is the Meilingmycin producer- Streptomyces nanchangensis , a lot of streptomycin-resistant ( str ) mutants were screened after the spores regenerated on the lethal media when they were treated with 4 different dosage of super-mutagent EMS. We have abtained the high-yield strain 80-5. 11-221 from these str mutants which only produces Meilingmycin and no Nanchangmycin in the rotation-flask experiments. The productivity of 80-5. 11-221 is 1521?g/mL 77. 9% higher than CK's 855?g/mL. After the shake flask fermentation experiment of 80-5. 11-221 for six generations, the productivity of F 2 and F 3 is stable and the productivity of F 4?F 5?F 6 decreases hastily with the increment of generations. It was showed that the chemical-resistance mutation of the strains had closely relation with yield mutation and the EMS dosage of the yield mutation was higher than the resistance-chemical mutation's through the statistical analysis between the dosage of mutation and the chemical-resistance mutational frequency?the variate capacity of the mutants' yield. A model of the resistance-chemical mutational labelling rational selection of the strain producing Meilingmycin was established.

Objective To explore the clinical features, diagnosis and treatment of Wunderlich syndrome (WS).Methods Fifteen patients with WS were included from September 2008 to February 2014, and their clinical features, diagnosis and treatment were retrospectively reviewed.The most common clinical manifestations were flank or abdominal pain (15/15), hypovolemic shock (5/15), gross hematuria (4/15) and percussion pain on kidney region ( 15/15 ) .Laboratory tests showed anemia ( 9/15 ) and coagulation abnormalities (5/15).Five of 15 cases were critical patients with moderate to severe shock ( systolic blood pressure≤90 mmHg, 1 mmHg =0.133 kPa ) accompanied with severe anemia ( Hb <60 g/L ) and coagulation abnormalities.Results In the acute stage, the diagnostic ratios of ultrasonography and contrast enhanced CT for WS were 11/15 and 15/15, and cause determination ratios were 4/15 and 10/15, respectively.The latter was significantly higher than the former ( P <0.05 ) .Contrast enhanced MRI was performed in 5 cases, and the results were identical to those of CT.According to the causes made by emergent imaging, critical patients underwent emergent operations or renal arteriography plus selective arterial embolization, and the other patients underwent conservative management, emergency operations, or renal arteriography plus selective arterial embolization, respectively.The causes of WS included angiomyolipoma (8 cases), renal cell carcinoma (3 cases), metastatic tumor of lung cancer (1 case) and renal cyst (3 cases) in this study.The mean follow-up period was 34 months.One critical patient died, and all the other patients were cured or relieved.Conclusions WS has no specific clinical features.Contrast enhanced CT or MRI is the main approach for diagnosis and cause determination, which is superior to ultrasonography.Treatments for WS vary according to severity classification and imaging diagnosis.

After testing the resistance of streptomycin to NS-41-80 Streptomyces Nanchangensis NS-41-80, the spores treated with 4 different dosage of super-mutagent EMS were regenerated on the lethal media, thus 3,000 streptomycin-resistant ( str ) str mutants were obtained. Then 202 spore mutants were screened through the pre-screening experiments and their yields are beyond 20% higher than the original strains respectively. In the re-screening experiments 48, 7 and 1 mutants were obtained whose yields are 100%, 200% and 300% higher than the original strains respectively and take the precentage of 23.76% and 1.60%, 3.46% and 0.23% and 0.5% and 0.03% of the number of the pre-screened strains and the rescreened strains respectively. Then 5 mutants were fermented whose yields are above 240% higher and the original strain through the continuous 3 batches fermentation, the yields are 57%～96.4% more than the original strains. Among them the yield of 80-5.3-165 is upwards of 6,000?g/mL and its norm is 5,855?g/mL. And a model of the streptomycin-resistance mutational screening of the strain producing Nanchangmycin was established.

Objective To study the difference in post-resuscitation lung injury between cardiac arrest induced by anoxia and ventricular fibrillation in porcine model.Methods WuZhiShan inbred miniature pigs were randomly (random number) divided into the asphyxia (AS,n =24) and ventricular fibrillation group (VF,n =24).Cardiac arrest (CA) was induced by endotracheal tube clamping or programmed electric stimulation.Cardiopulmonary resuscitation (CPR) or defibrillation was performed for returning of spontaneous circulation (ROSC).Pulmonary perfusion/ventilation measured with isotope scanand positron emission tomography-computed tomography (PET-CT) scanning were done before and 4hrs after ROSC.The oxygenation index (OI),respiratory index (RI),oxygen delivery (DO2),blood lactic acid,and dynamic pulmonary compliance (Cdyn),airway resistance (Raw),extra-vascular lung water index (EVLWI),pulmonary vascular permeability index (PVPI),were measured before cardiac arrest,ROSC 0 h,ROSC15 min,ROSC 30 min,ROSC 1 h,ROSC 2 h,ROSC 4 h and ROSC 6 h.All pigs were sacrificed with euthanasia at ROSC 6 h and the lungs were dissected for observing histopathological changes.The level of Na +-K +-ATPase,Ca2+-ATPase,superoxide dismutase (SOD),Methane Dicarboxylic Aldehyde (MDA),Bcl-2,Bax,Caspase3 and apoptosis index (AI％) in lung were measured.Results The ROSC rate and ROSC 6hrs survival rate of in AS group was lower (P ＜0.01) than those of the VF group.The damages of lung in AS group were more severe than that in VF group by the results of enzymology and protein detection (Na +-K +-ATPase,Ca2 +-ATPase,SOD,MDA,Bax,Bcl-2 and Caspase3).AI％ was higher in AS group (P＜0.01).The deterioration of the indexes (OI,RI,DO2,Lac,Cdyn,Raw,EVLWI,PVPI) at all time points were more severe in AS group than those in VF group.Obvious filling-defect was found by the PET-CT scan of both groups,but not revealed by the isotope scan.Conclusions The lung injury after CA was closely related to the cause of CA rather than the external chest compression.Asphyxia induced more serious lung injury than ventricular fibrillation.
