The inhibitory effects of growth-inhibitor on the growth of Isochrysis galbana, malondialdehyde (MDA) content and activities of antioxidant enzymes (superoxide dismutase and peroxidase) were studied. And the inhibition effects of 4 species of antioxidants on this damage to its cells were also investigated. The results showed that 0.10 mg/L of GI marked decreased cell densities, activities of superoxide dismutase (SOD) and peroxidase (POD), and MDA content increased. With increase of GI concentrations, cell densities and activities of SOD and POD decreased sharply, and MDA content increased obviously. When concentration of GI was 0.30 mg/L, the cell densities, activities of SOD and POD decreased to 0.05, 0.56 and 0.59 folds of the control, respectively, and MDA content increased to as higher as 2.2 folds of that of the control set. L-Ascorbic acid, citrazinic acid, lenediamiaetetraacetic acid disodium salt (Na2EDTA) and 3-tert-butyl-4-hydroxyanisole could decrease MDA content obviously, and marked increased cell densities and activities of SOD and POD. When 4 species of antioxidants were added to the medium, the cell densities, and activities of SOD and POD increased to as high as 1.38～1.90, 1.49～2.12 and 1.55～2.13 folds of that of the control set, respectively, and MDA content decreased by 57.7%～87.9%. It was indicated that the excess active oxygens were produced under growth-inhibitor stress and active oxygen participated in the damage of growth-inhibitor to Isochrysis galbana; the L-ascorbic acid, citrazinic acid, lenediamiaetetraacetic acid disodium salt and 3-tert-butyl-4-hydroxyanisole could effectively inhibit membrane lipid peroxidation and further alleviated algal damage.

Objective To investigate the early post-operative nutritional support for kidney transplant recipients.Methods Totally 67 patients who received early post-operative nutrition supports were randomly divided into three groups:group A (n = 24,relatively high nitrogen intake),group B (n = 25,intermediate nitrogen intake) and group C (n = 18,relatively low nitrogen intake).Two weeks after operation,albumin,hemoglobin,the nutrition indieators,serum lipids,and renal function 1 day before operation and 2 weeks after operation were evaluated. Results Body weight was significantly different among three groups;the nitrogen balance in group A was significantly better than those in groups B and C (P ＜0.05);albumin and hemoglobin were not significantly different between group A and group B (P ＞ 0.05),but were significantly higher than those in group C (P ＜ 0.05).The renal function in group C was significantly better than those in group A and group B (P ＜ 0.05).The triglyceride level was not significantly different among three groups,while the cholesterol level in group A was significantly higher than those in group B and group C (P ＜ 0.05),but not between group B and group C.Conclusion Proper nitrogen intake in early post-operative nutrition support can improve the recovery of renal function and nutritional status in kidney transplant recipients.

Objective: To assess the peculiarity in fluorine-18 fluorodeoxyglucose (FDG) uptake in patients with bronchial alveolar carcinoma. Methods: From December, 1998 to April, 2002, 22 patients with bronchial alveolar carcinoma (BAC) were imaged with FDG-PET (positron emission tomography) before surgery. Their maximum and mean standard uptake value (SUVmax and SUVmean ) of tumor and SUV of normal lung (SUVlung) were measured. Results: All tumors were detected by FDG-PET. FDG uptake of tumor was higher than that of normal lung (P

[Objective] To observe the clinical effect of TCM diet therapy on type-2 diabetes.[Method] Select the said patients 76 cases,randomly divide them into treatment group and control group with 38 cases in each group,which were administered with routine western medicine,while the treatment one was added with TCM diet medication.[Result] Compare the fasting glucose before medication,showing marked difference(P

In allusion to high labor intensity, low working efficiency and high error rate in hospital laboratory, a detection system of the enzyme-linked analyzer based on Multiscan EX instrument is developed. Being easy to operate, the detection system proves effective in enhancing working efficiency. It deserves popularizing because of its comprehensive applications to the detection.

With a PII-300 computer, an intelligentized microcomputer system for HBV marker detection and reporting is developed in this paper, which is based on Windows operating system and accomplished through Visual Basic6.0. More than 10, 000 cases have proved that the result from the system accords with the one from artificial detection completely. This system solves the problems in hospital laboratory such as high labor intensity, low working efficiency and high error rate, and thus a quantitative detection method for HBV marker comes into existence.

Objective To study on wavelet transform in calcium sparks image de-noising when excitation contraction cou-pling(ECC) was studied and researched by scanning confocal microscopy,in order to elucidate the mechanism of ECC.But due to the noise exist in most calcium sparks image,it is hardly to recognize and analyze the useful information of calcium sparks.So how to increase the signal-to-noise rate is very important in calcium spark studying.Methods By using the self-developed software based on multi-scale wavelet transform to remove the noise exists in the calcium sparks images.Results The experiments shows that the method can be increased the signal-to-noise rate in about 80 calcium sparks images.Con-clusion The new method for calcium spark expression and spatial and temporal analysis is provided.

Objective To discuss the method of calling MATLAB in VB application program based on ActiveX.Methods MATLAB provided automatic service support to ActiveX,and MATLAB could be called as ActiveX of interpreter through ActiveX automatic interface.Results Good effect was achieved when this method was applied to noise filtering of patch clamp.Conclusion By using this method,users can embedded mix programming in self-developed application software conveniently,thus reducing the difficulties in programming.

Objective To investigate the clinicopathological characteristics, diagnosis and treatment of huge adrenal tumor.Methods Retrospectively analysed the clinical data of the 2 patients with huge adrenal tumor more than 10 cm in diameter, who were admitted in our hospital from September 2013 to January 2015.Clinical manifestations, treatment and prognosis were evaluated.Results Two patients were both suspected of adrenocortical carcinomas.Case 1 was a 28-year-old female.Laparoscopic surgery was performed at first but was conversed to open palliative adrenalectomy due to tumor rupture and bleeding.The postoperative pathology was adrenocortical carcinoma.The patient died of gastrointestinal bleeding caused by tumor metastasis 10 months later.Case 2 was a 39-year-old female, who underwent laparoscopic adrenolectomy with tumor excision completely.The postoperative pathology showed neoplasm of malignant potential, and no tumor recurred in 15 months follow-up.ConclusionsOpen surgery should be the priority if the diameter of adrenal tumor is more than 10 cm and diagnosis as suspicious of malignancy.Huge adrenocortical carcinoma is related to poor therapeutic response,and multimodality therapy may improve the prognosis.

Objective To compare the effects of thoracoscopic 2 hole and 3 hole for congenital pulmonary bulla resection.Methods 38 cases of congenital pulmonary bulla patients,both in the VATS downlink congenital pulmonary bulla resection.According to the number of holes,thoracoscopic operation were divided into the two groups. To observe the use of group 19 cases of 2 holes,19 cases 3 holes were adopted in the control group.Pull the chest tube operation time,operation time of the two groups were compared after.and the average hospitalization time after opera-tion,postoperative analgesia drug application.Results The observation group operation time,operation time,pulling the chest tube after operation the average hospitalization time, analgesic drug application rate respectively were (46.89 ±9.11)min,(3.95 ±0.85) d,(7.37 ±1.34) d,21.1%,The control group were (66.05 ±12.09) min, (4.37 ±0.98)d,(7.32 ±1.57)d,52.6%.There were statistically significant differences in rate of the two groups in operation time,analgesic drug application.(t=-5.516,χ2 =4.071,P<0.05);38 cases were cured,followed up for 3-24 months,no recurrence occurred in 1 cases.Conclusion Video assisted thoracic descending congenital pulmona-ry bulla resection,the 2 hole 3 hole more than minimally invasive,short operation time,postoperative analgesic use rate is low.
