Objective To establish the method of thin layer identification of Phellodendri Chinensis Cortex and solid phase extraction - high performance liquid chromatography (SPE-HPLC) determination of the content of phellodendrine in Leshu Lotion. Methods Thin layer chromatography (TLC) was used for qualitative identification of Phellodendri Chinensis Cortex in Leshu Lotion and the Bond Elutplexa PCX strong cation-exchange solid phase was used for extraction small column purification. Platisil-NH2 column was as chromatographic column; column temperature was 30 ℃; triethylamine pH 3.82 (phosphoric acid), tetrahydrofuran, acetonitrile was 18:12:70, isocratic elution; flow rate was 1.0 mL/min; detection wavelength was 286 nm. Results TLC could obviously identify active ingredients of phellodendrine in Phellodendri Chinensis Cortex. The phellodendrine had good linear relationship between concentration and peak area within the scope of 1.22–12.2 μg (r=0.9999); the average recovery rate of phellodendrine was 101.18%, RSD was 1.71%. Conclusion This method is simple to operate, with accuracy and repeatability, and can be used for quality control of Leshu Lotion.

Objective To explore the clinical value of plasma D -D and blood glucose change in treating patients with bone trauma.Methods Selected 200 patients with bone trauma as the observation group,60 cases of healthy persons as the control group.The plasma D -D and blood glucose of the two groups were detected,and the results were analyzed.Results The plasma D -D and blood glucose of the observation group were more than those of the control group,and it was gradually reduced from first day to third day and fifth day.The plasma D -D of the observation group was (174.7 ±40.2)μg/L,blood glucose was (5.2 ±0.4)mmol/L.The plasma D -D of first day, third day and fifth day of the observation group were (1 452.6 ±303.4)μg/L,(982.2 ±215.2)μg/L,(705.6 ± 152.9)μg/L respectively.The blood glucose of first day,third day and fifth day of the observation group were (14.2 ±2.3)mmol/L,(10.3 ±1.2)mmol/L,(7.6 ±1.9)mmol/L,respectively.The difference was statistically sig-nificant(F =3.49,P <0.05).In the observation group,the more severe injury in patients,the higher plasma D -D and blood glucose,and it was gradually reduced from first day to third day and fifth day,the difference was statistically significant(F =4.83,P <0.05).Conclusion In judging the condition of bone trauma,it is important to measure plasma D -D and blood glucose levels,and this method should be popularized in clinical use.

A central portion of nifS, designated nifS', was amplified from Azotobacter vinelandii. The nifS' was cloned into pUC18 to make pUCS. Then pUCS was integrated into Azotobacter vindandii chromosome DNA by homologous recombination. This nifS disruption mutants were generated by single cross-over event and selected by Amp resistence on BBGN medium. The nifS disruption mutant (named SU1) was affirmed by southern blot and PCR amplification. SU1 grows rapidly on BBGN, but very slowly on Burk's N-free medium. This phenomenon showes that SU1 nearly lost its nitrogen fixation ability because of the disruption of nifS. The successful construction of SU1 is helpful for further research on the effect of nifS on the structure and function of nitrogenase component-Ⅰ and Ⅱ.

Abstract?AIM: To investigate the influence on blood-retina barrier after intense light exposure in rats.?METHODS: The rats were randomly divided into light exposure group and control group. Rats in light exposure group were exposed in white light (10000lux, 12h on-off, continuing 1-14d) .Rats in control group were only exposed in natural light.The eyes of the rats in the two groups were removed when the rats in light exposure group acceptted intense light after 1, 3, 7 and 14d.We observed the change of retinal structure using hematoxylin-eosin ( HE ) staining, and observed the change of retinal ultrastructure using electron microscope.We quantified the change of retinal vascular permeability using laser scanning confocal fluorescence microscope and spectrophotometry after perfusion of Evans-blue, to evaluate the change of blood-retinal barrier.?RESULTS: At 1d after intense light exposure, the retinal ultrastructure of rats changed, such as denaturation of photoreceptor cells and falling of membranous disc outer segment and thinning of the outer nuclear layer thickness, and so on;and the longer the rats exposure to intense light, the more serious change of the retinal ultrastructure were found.At 3d later, photoreceptor cells began apoptosis.At 14d later, the outer nuclear layer became thinner obviously, and the number of cells reduce obviously.At 1d after intense light exposure, EB leaked from the retinal vascular, and at 14d later the leaking of EB was more obvious.?CONCLUSION: The photoreceptor cell of the outer nuclear layer of retina will degenerate and apoptosis, and the outer nuclear layer will be thinner, and the structure and function of blood-retinal barrier will be destroied, if the eyes of rats exposed in intense light.

Objective To investigate the expression and clinical value of miR-127-3p in plasma of patients with breast cancer .Methods 80 cases of breast patients , 70 cases of benign breast tumor patients and 70 cases of normal control group were recruited .A real-time fluorescent quantitative reverse transcription polymerase chain reaction ( RT-PCR ) method for detecting miR-127-3p was established; Liner, reproducibility, and specificity were evaluated.In addition, correlations between the relative expression of plasma miR-127-3p and the concentrations of CEA and CA 153 were assessed.the relationship of miR-127-3p expression and clinicopathological features was further determined by Mann-Whitney test.Results The method for detection of plasma miR-127-3p was established.The relative plasma expression of miR-127-3p in breast patients [ 10.561 ( 5.424 -16.465 ) ] was significantly higher than that in benign breast tumor patients [3.015 (1.987-5.035)] (P=0.000 6) and healthy controls [2.375 (1.173-4.370)] (P=0.000 2).However, there was no significant difference between benign tumor patients and healthy control group (P=0.143).Positive relationship was found between the relative expression of miR-127-3p and the concentration of CA153 (R2 =0.457, P=0.003).The area under the ROC curve (AUC) of miR-127-3pwas 0.763, which was higher than that of CEA and CA 153.No significant difference was found between plasma miR-127-3p expression and clinicalpathological features including tumor size , differentiation and tumor node metastasis stage (P>0.05).Conclusions miR-127-3p was increased in breast cancer patients and may be an important diagnostic index for breast cancer .

ObjectiveTo analyze the clinical outcome of locking plate and hemiarthroplasty in treatment of Neer three- and four-part proximal humeral fractures.Methods A totalof 63 consecutive patients aged over 55 years with Neer three- and four-part proximal humeral fractures were treated surgically from June 2006 to June 2010.In the retrospective study,36 patients were treated by open reduction and locking plate fixation ( locking plate fixation group) and 27 patients treated by hemiarthroplasty (hemiarthroplasty group).Clinical outcomes including operation time,blood loss,visual analog scale ( VAS),Constant-Murley score and complications were evaluated.ResultsThe average 19.7 months follow-up showed complication rate of 28％ in the locking plate group,including one patient with varss malunion,one with axillary nerve injury,one with humeral head necrosis,one with heterotopie calcification and four with impingement syndrome.The complication rate was 24％ in the hemiarthroplasty group,including two patients with tuberosity nonunion,one with tuberosity migration,one with impingement syndrome and one with joint semiluxation.The mean Constant-Murley score of three-part fractures in the locking plate group was ( 76.5 ±5.8) points,better than (69.2 ±7.2) points in the hemiarthroplasty group (P ＜0.05 ).While the two groups showed no significant differences with regards to operation time,blood loss and visual analog scale (VAS).As for the four-part fractures,the mean operation time was shorter and the mean blood loss was less in the hemiarthroplasty group compared with the locking plate group (P ＜0.05),while there were no obvious differences in VAS score and Constant-Murley score between the two groups. Conclusions Both locking plate and hemiarthroplasty are the reliable methods for the three- and four-part proximal humeral fractures.The patients' age,bone quality,fracture type,comminution degree and evaluation of osteonecrosis possibility,are critical for surgery decision.

Objective To investigate the effect of sterol regulating element binding protein (SREBP1c) and its ac-tive form (SREBP1cm) on human protein kinase R-like endoplasmic reticulum kinase (PERK).Methods Re-porter victors of PERK promoter and its truncations were constructed with pGL 3-basic and co-transfected with internal reference pRL-SV40 into cell and luciferase activity was detected .pcDNA3.1 ( -)-SREBP1c or pcDNA3.1 ( -)-SREBP1cm was co-transfected with PERK promoter transcriptional activity core regions and the detection of dual -lu-ciferase reporter gene was used to analyze the regulation of SREBP 1c/1cm on PERK promoter transcriptional activity . The expression level of PERK mRNA and protein were detected by RT-PCR and Western blot .Results PERK pro-moter and truncations were successfully constructed into pGL 3-basic, and PERK promoter core area of transcription-al activity had determined;Dual-luciferase report gene showed that SREBP 1c inhibited PERK promoter transcrip-tional activity and SREBP1cm promoted PERK promoter transcriptional activity .RT-PCR and Western blot showed that SREBP1c decreased PERK mRNA and protein expression , but SREBP1cm increased PERK mRNA and protein expression, which was consistent with the detection of dual-luciferase report gene .Conclusions SREBP1c and SREBP1cm have a opposite regulation effect on PERK promoter transcriptional activity and its expression .

One hundred and fifty two actinomycetes were isolated from forty two radiation-polluted soil samples,using six different isolation media. Sixty cultures were chosen for 16S rRNA gene sequence and systematic analysis,which based on their morphology and ARDRA. Results of 16S rRNA gene sequences blasting showed that the strains were assigned to 12 recognized genera of actinomycetes,most of them fall within Streptomyces genus and a great deal of strains belonged to rare actinomycetes,which indicated a rich diversity of actinomycetes in the radiation-polluted soil.

Cancer-related fatigue (CRF) is a common symptom which associated with cancer itself or cancer treatments. CRF will not only interrupt the patient's treatment, but also affect the patient's quality of life seriously. To date, the pathogenesis of CRF is still unclear, and recognized effective treatment is lacking. It is the precondition of establishing standardized animal models for CRF to find effective treatments. This paper summarizes the animal model of CRF in order to find suitable methods, and distinguish the effects of different interventions.
