The strain Acidiphilium cryptum DX1-1 producing PHB was irradiated respectively by UV and Co60 to raise PHB production. The results indicated that the effect of UV better than using Co60. One strain of the UV mutagenized called UV60-3 has the highest PHB production yield, showing final PHB concentra- tion of 28.56 g/L, 1.45 times higher than that of original strain. FT-IR spectroscopy analysis shows that the polymers obtained from the strain DX1-1 have the same IR spectra of standard PHB. Further research about the best appropriate C/N ratio of the mutant was done. The optimum ratio of C/N was about 3.76, the final PHB concentration reaches to 30.57 g/L.

There have been very few studies on the effect of Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction in inhibiting apoptosis in myocardial ischemial injury caused by coronary heart disease. In this experiment, Gualou Xiebai Banxia decoction combined with-Xuefu Zhuyu decoction were used to intervene the miniature swine phlegm and blood stasis type coronary heart disease model, in order to observe the effect of the combined prescription on the myocardial apoptosis and the expressions of Bcl-2, Bax, Caspase-3, Caspase-9 in the model. Totally 15 Chinese experimental miniature swine were adopted and randomly divided into the control group, the model group and the phlegm and stasis-treating group. The model group and the stasis-treating group were fed with high fat diets for two weeks, intervened with the coronary artery injury and then given drugs and high fat diets for eight weeks. The control group was fed with ordinary diets for 10 weeks, without the coronary artery injury. After the experiment, myocardia at the juncture of infracted areas were collected and made into formalin-fixed paraffin sections. The TDT-mediate dUTP nick end labeling (TUNEL) assay was used to detect the myocardial apoptosis. The immunohistochemistry (IHC) technique was applied to detect Bcl-2, Bax, Caspase-3, Caspase-9 levels in myocardial tissues. According to the findings, the apoptosis indexes (AI) for the control group, the model group and the phlegm and stasis-treating group were 0.92%, 27.68%, 17.28%, respectively. The AI of the phlegm and stasis-treating group was significantly lower than that of the model group (P < 0.01). Compared with the model group, the phlegm and stasis-treating group showed significantly higher Bcl-2 protein expression (P < 0.01) and lower Bax, Caspase-3 and Caspase-9 protein expressions (P < 0.01). In conclusion, Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction have a significant protective effect against the myocardial apoptosis in miniature swine phlegm and blood stasis type coronary heart disease model.

OBJECTIVETo observe the improvements of synchronous treatment of bilateral scalp acupuncture and rehabilitation training on activities of daily life in patients with cerebral infarction at acute phase, so as to compare the efficacy differences between scalp acupuncture at bilateral and affected side as well as differences between synchronous and non-synchronous treatment.

METHODSNinety patients of acute-phase cerebral infarction with motor dysfunction were randomly divided into three groups. The observation group was treated with synchronous treatment of scalp acupuncture at the Dingzhongxian (middle line of vertex), bilateral Dingnieqianxiexian (anterior oblique line of vertex-temporal) and bilateral Dingniehouxiexian (posterior oblique line of vertex-temporal) and rehabilitation training; the control group A was treated with synchronous treatment of affected scalp acupuncture at the Dingzhongxian, affected Dingnieqianxiexian and affected Dingniehouxiexian and rehabilitation training; the control group B was treated with bilateral scalp acupuncture for 4 h, followed by rehabilitation training. All the patients took the treatment once a day, and 6 days for a course of treatment for total of 4 courses. The modified Barthel index (MBI), activities of daily living (ADL) and Fugl-Meyer motor assessment (FMA) were used to perform efficacy assessment before treatment, in the 14th days of treatment and in the 28th days of treatment in three groups.

RESULTSAfter treatment, three indices at each time point were superior to those before the treatment in three groups (all P<0.01) ; the improvements of ADL and FMA in the observation group after 28 days of treatment were superior to those in the control group A and control group B (all P<0.05), and the improvement of MBI was superior to that in the control group B (P<0.05).

CONCLUSIONThe synchronous treatment of bilateral scalp acupuncture and rehabilitation training could significantly improve the activities of daily life and motor function in patients with cerebral infarction at acute phase, which is superior to scalp acupuncture at affected side and non-synchronous treatment.

Objective To explore the relationship between serum homocysteine (Hcy) level before coronary angiography(CAG) and contrast induced nephropathy (CIN) after CAG.Methods We included 2264 cases of suspected coronary heart disease from May 2013 to May 2016 and all patients received CAG examination.According to whether CIN has developed or not after CAG, the patients were divided into the non-CIN group (n=2162) and the CIN group (n=102).We analyzed and compared the clinical baseline data, serum Hcy and creatinine (Cr) levels and the estimated glomerular filtration rate between the 2 groups eGFR.Results Patients in the non-CIN group were younger and with less comorbidities of diabetes and chronic kidney disease (all P<0.05).The volume of contrast media consumed in the non-CIN group was less than the CIN group [(122±21)ml vs.(147±24)ml, P=0.012).Hcy level in the non-CIN group (12.81±6.71) μmol/L was lower than that in the CIN group (21.74±11.9)μmol/L before CAG (P<0.05).No significant differences in serum Cr level and eGFR before CAG (P>0.05).At 72 hours after CAG, Cr level of the non-CIN group (69.34±19.54 μmol/L) was lower than that of the CIN group (87.34±21.38) μmol/L (P<0.05).eGFR was higher in the non-CIN group (79.34±19.54)ml/min than that in the CIN group (67.34±21.38)ml/min (P<0.05).Linear regression analysis showed that Hcy level before CAG were positively correlated with Cr level after CAG (r=0.547,P<0.01) and negatively correlated with eGFR after CAG (r=-0.271,P<0.01).Conclusions Hcy level before CAG can be used as one of an effective parameter to predict CIN.

Objective:To investigate the value of chest CT quantitative index in clinical classification and lung injury severity evaluation of COVID-19.Methods:The current study retrospectively analyzed the clinical and CT data of 438 patients with COVID-19 between January 2020 and March 2020 in Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology. The clinical types included common type ( n=146), severe type ( n=247) and critical type ( n=45). The chest CT indexes of all patients were quantitatively analyzed by artificial intelligence (AI) deep learning, including whole lung volume, CT lung opacification, ground glass opacification volume (GGO volume; CT value<-300 HU), solid opacification volume (SO volume; CT value ≥-300 HU) and the ratio of volume to the whole lung volume, the ratio of SO volume to GGO volume (SO volume/GGO volume). Kruskal-Wallis test was used to conduct statistical analysis of the differences in quantitative parameters among clinical types, and multiple ordered logistic regression was used to analyze the correlation between quantitative parameters and clinical types. Results:Among the 438 patients diagnosed with COVID-19, severe and critical patients were older ( P<0.05), and most of the critical patients were male ( P<0.05). The main clinical manifestations of all clinical types were fever, followed by cough, fatigue, chest tightness, dyspnea, gastrointestinal symptoms and so on. GGO volume was the main CT manifestation of all the three clinical subtypes. The whole-lung opacification volume, GGO volume, SO volume and their proportions in whole-lung volume significantly increased from common, severe to critical types (all P<0.05). SO volume/GGO volume increased with the severity of clinical type [common type 0.12 (0.03, 0.34), severe type 0.29 (0.11, 0.59), critical type 0.61 (0.39, 0.97)]. Multiple ordered logistic regression analysis showed that whole-lung opacification volume (OR=1.009), SO volume/GGO volume (OR=1.866), GGO volume (OR=1.008) and SO volume (OR=1.016) had a significant positive effect on the severity of clinical typing ( P<0.01). Conclusion:Quantitative indicators of chest CT based on deep learning algorithm (SO volume, GGO volume, SO volume/GGO volume) are closely related to the clinical severity of COVID-19.
