The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.

Background Even though the change in wavefront aberrations with correction modality is well documented in the literature,little is known about the underlying mechanism.Complete understanding of the causes responsible for the wavefront change in the combined lens-eye system is important since it provides basic knowledge for further improving the technique to correct refractive error by correcting lenses.Objective The aim of this study was to investigate the influence of refractive correction lens on optical property of the eye by analyzing Zernike aberrations in myopic eyes with contact lens correction.Methods This study was approved by the Ethic Committee of Wenzhou Medical College.Written informed consent was obtained from each subject before entering this study.Zernike aberrations of 52 myopic eyes of 26 subjects with the spherical equivalent-1.75 to-8.50 D were measured using a Hartmann-Shock wavefront sensor.The human eye aberrations were examined at the uncorrected condition,rigid-gas-permeable contact lens (RGP-CL) corrected condition and soft contact lens (Soft-CL) corrected condition.The differences of wavefront aberrations and Zernike coefficients were compared by repeated measurement of single factor variance analysis,and correlation of the aberration changes between uncorrected condition and RGP-CL corrected condition or Sofi-CL corrected condition,between the right eyes and left eyes in different conditions were analyzed by Pearson linear correlation.Results Mean total root-mean-square (tRMS) was (0.71 ± 0.30)μm,(0.54±0.19)μm and (0.74±0.32)μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference (F =8.758,P＜0.001),and tRMS was significant declined under the RGP-CL corrected condition compared with uncorrected condition (t =2.746,P =0.008),and tRMS in RGP-CL corrected condition was significantly lower than that in Soft-CL corrected condition (t =3.428,P =0.001).The high RMS (hRMS) was (0.34±0.12) μm,(0.28 ±0.12) μm,(0.40±0.14) μm in the uncorrected condition,RGP-CL corrected condition and Soft-CL corrected condition,with a significant difference among them (F =10.681,P＜0.001).An insignificant decrease of hRMS was seen in the RGP-CL corrected condition compared with uncorrected condition (t =1.987,P=0.053),but hRMS value was significant higher in the Soft-CL corrected condition than that in the uncorrected condition (t=2.101,P=0.041) and RGP-CL corrected condition (t=4.266,P＜0.001).Compared with uncorrected condition,the axis astigmatism (C5) and spherical aberration (C12) in the RGP-CL corrected condition and spherical aberration (C12) in the Soft-CL corrected condition were significantly reduced (P＜0.05),and the absolute values of trefoil (C6),vertical coma (C7) and tetrafoil (C10) in the RGP-CL corrected condition were lower than those of the uncorrected condition,but vertical coma (C7) absolute value in the Soft-CL corrected condition was increased (P＜0.05).A significantly positive correlation was seen in the spherical aberration (C12) between the RGP-CL corrected condition and uncorrected condition (r =0.763,P＜0.001),and less significant correlation was in the secondary astigmatism (C11) between the Soft-CL corrected condition and uncorrected condition(r=0.469,P＜0.001).Conclusions Different contact lens corrected conditions exert their effects on ocular wavefront structure due to its unique interaction with the eye.RGP-CL wearing has strong modification on wavefront aberrations probably due to its molding effect on corneal surface,which reduces the bilateral symmetry.High order wavefront aberration can be modified by Soft-CL wearing.

Objective To compare the diagnostic value of adenosine and exercise stress myocardial perfusion imaging (MPI) for detecting coronary heart disease (CHD) in women. Methods One hundred and thirty-eight patients with CHD were randomly divided into two groups: adenosine stress group (n = 69)and exercise stress group (n = 69). All patients underwent myocardial SPECT evaluation. Coronary angiography (CAG), referred as "gold standard" , was performed in each patient within 1 week before or after MPI. The diagnostic value of the two stress MPI was compared with χ2 test or Fisher's exact test. Results In adenosine stress group, the sensitivity, negative predictive value and accuracy were 88.2% (45/51),72.7% (16/22), 88.4% (61/69), respectively, which were not significantly different from those of the exercise stress group (91.7% (44/48), 66.7% (8/12), 81.2% (52/64); χ2 =0. 571, 0. 714, 0.249, P >0.05). However, the false positive rate of adenosine stress (11.1%, 2/18) was significantly lower than that of exercise stress (50.0%, 8/16), P = 0.023. Conclusions Adenosine and exercise stress MPI have similar value for CHD diagnosis in women, however, adenosine stress MPI may have an advantage of low false positive rate.

Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective To study effective treatment for deep burn on the face caused by coal-dust burning and blasting to prevent severe disfigurement.Methods Early conservative eschar-scraping, delayed skin graft,early strain-diminution for the eyelids in both sides,and wound expansion with skin graft were used to treat 12 patients with deep burn on their faces caused by coal-dust burning and blasting. Results Facial wound of all the 12 patients healed within three weeks after burn.No significant cicatricial hyperplasia and deformity were found on their faces during three-month follow-up,with natural facial expression and abundant emotion.Conclusions Early eschar-scraping and delayed skin graft for deep facial burn can promote fast repair of burn-wound,diminish cicatricial hyperplasia and prevent deformity on the face.

OBJECTIVETo observe the clinical efficacy of Xiaoshui decoction (XSD) combined with intrapleural perfusion of cisplatin in the treatment of malignant pleural effusion.

METHODSFifty-one patients with malignant pleural effusion were randomly assigned to two groups. The treated group (26 patients) received oral administration of XSD combined with intrapleural perfusion of cisplatin, and the control group (25 patients) was only treated with intrapleural perfusion of cisplatin. The effects of the short-term efficacy, quality of life scores and clinical symptom scores of malignant pleural effusion were evaluated.

RESULTSThe short-term efficacy in the treated group and the control group was 72.0% and 58.3%, respectively, and no significant difference was found (P>0.05). In contrast, the quality of life in the treated group was significantly improved compared to that of the control group (P<0.05), and so was the symptom remission (P<0.05).

CONCLUSIONSThe combined therapy of XSD and intrapleural perfusion of cisplatin did not show obvious improvement in short-term efficacy, but the therapy remarkably alleviated the symptoms and improved the quality of life of patients.
