ObjectiveTo investigate the relation between body mass index(BMI) and postoperative complications after coronary artery bypass grafting (CABG).MethodsThe clinical data of 99 patients who underwent CABG at Fujian Provincial Hospital were analyzed. The patients were divided into three groups according to their preoperative BMI: normal group(n=21), overweight group(n=33), and obese group(n=45). And the related observation indexes were compared among the 3 groups.ResultsThe hospital mortality of normal, overweight and obese groups were 0%, 3.03% and 4.44% respectively (P>0.05). The rate of pulmonary infection (24.44%) or wound infection (24.39%) in the obese group was significantly higher than those in the normal group(4.76% or 0%) (P<0.05). The time stay ICU or hospital in the obese group were significantly greater than those in the normal and overweight groups (P<0.05). 6-minute walking test (6MWT) in the obese group was significantly less than that in the normal and overweight groups 3 months after the operation(P<0.001).ConclusionHigh preoperative BMI can take a negative effect on patients after CABG following postoperative complications.

The key point of study on CO2 removal by microalgae cultured in a photobioreactor is to improve CO2 removal capability. In this paper, a model of air-lift photobioreactor was developed by combination of conditions including the velocity of flow, the degree of mixing, the gas-liquid mass transfer and the rate of photosynthesis, and two corresponding simplified methods, such as time discretization and lumped parameters were put forward. Using a method of lumped parameters, the model for simulation of time course of DO, pH in the column air-lift photobioreactor and prediction of CO2, O2 concentrations in the outlet gas under different CO2 concentration in the aeration gas was thoroughly discussed. Experimental data were also used to verify the model which could potentially be applied to rational design of the photobioreactor, high-density culture of microalgae and efficient removal of CO2.

Chloroplast genome sequences have comprehensive application prospects in DNA barcoding and chloroplast engineering in traditional Chinese medicine. The complete chloroplast genome of Magnolia officinalis sequenced by high-throughput pyrosequencing and a sequencing procedure was established. Fourteen contigs were obtained after de nove assembly. The sequencing percent of coverage was 99.99%. The chloroplast genome is 160 183 bp in size, and has a typical quadripartite structure with the large (LSC, 88 210 bp) and small copy (SSC, 18 843 bp) regions separated by two copies of an inverted repeat (IRs, 26 565 bp each). chloroplast genes were successfully annotated, of which 17 genes located in each IR region. The chloroplast genome features in Magnolia officinalis are nearly identical to those from other Magnoliid chloroplast genomes. Phylogenetic analyses were performed based on 81 shared coding-genes for a total of 9 Magnolia samples of 5 closely related species. Results showed that distinguishing among species was generally straightforward at the species and population level. This study confirmed the effectiveness of our chloroplast genome sequencing procedure. The chloroplast genome can provide distinguishing differences to help identify Magnolia officinalis and its closely related plants.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.
