Background Proliferative vitreoretinopathy (PVR) is one of the major causes of retinal detachment surgery failure.Based on proteomic studies of PVR vitreous,the insulin-like growth factor binding protein-6 (IGFBP-6) protein was specifically expressed in the vitreous and serum of PVR patients.Furthermore,its expression level is higher in the vitreous and serum in severe PVR patients than that in mild PVR patients.Objective This experiment was to detect the expression of IGFBP-6 in a PVR rat model.Methods Seventy 7-week old male SPF Wistar rats were included and were randomized into the PVR model group and control group.A mixture of RPE-J cell suspension(5 μl) and platelet-rich plasma (5 μl) was intravitreally injected in the left eyes of adult Wistar rats to establish the PVR model,and normal saline solution was administered in the same way in the control group.The rat eyes were clinically examined 1 week,2,3 and 4 weeks after injection,and PVR was graded based on the criteria of Francine.The animals were sacrificed after 1 week,2,4 or 8 weeks for the preparation of retinal sections and liver extraction.Expression levels of IGFBP-6 mRNA in the rat retina and liver were assayed by real-time Q-PCR.The expression of IGFBP-6 protein in the rat serum and vitreous was detected by ELISA.The use of animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results Purified IGFBP-6 RNA was extracted from the liver and retina of Wistar rat and quantified by real-time Q-PCR.The expression level of IGFBP-6 mRNA in retina was (3.79± 1.33) × 10-4 in the PVR model rats,showing a significant decline in comparison with the control rats with a level of(8.32±2.96) × 10 4,4 weeks after injection (t =3.42,P＜0.01).The expression of IGFBP-6 mRNA in the 4th week was significantly lower than that of 1 week,2 or 8 weeks after the establishment of the PVR model(P＜0.05).No significant difference was found in the IGFBP-6 mRNA level in the liver between the PVR group and control group(27.60± 14.01 × 10 4 vs.25.01 ± 12.04 ×10-4,respectively),as well as among the different time points(P＞0.05).IGFBP-6 mRNA content in the retina was significantly reduced in grades 1,2 or 3 of the PVR groups compared with the control group(P＞0.05),but there was no significant difference among the different grades of PVR groups (P＞0.05).Concentrations of IGFBP-6 protein in grades 1,2 and 3 of the PVR model group were (221.00 ± 19.32),(229.63 ± 18.89) and (225.70 ± 26.71) μg/L,with a significant elevation in comparison with (173.25 ±21.11) μg/L of the control group (t =2.14,P＜0.05).However,there was no significant change among the different grades of PVR groups(t=1.24,1.46,P＞0.05).The concentrations of IGFBP-6 protein in the vitreous and serum were higher in PVR rat samples (vitreous:225.44±19.36 μg/L;serum:108.48 ± 15.78 μg/L) than in control rats (vitreous:173.25 ± 21.11 μg/L,serum:95.96 ±17.40 μg/L)(P＜0.05).Conclusions The concentrations of IGFBP-6 protein in the vitreous and serum increase in PVR rats.The results indicate that the increased IGFBP-6 in the vitreous might be a localized autocrine secretion of the eye.

Objective To provide the guidance for the control and treatment of blood stream infec-tion caused by Serratia marcescens strains through analyzing the homology and drug resistant genes of the iso-lates collected from the Intensive Care Unit ( ICU) of Shaoxing County Central Hospital.Methods Serratia marcescens strains were isolated from ICU patients with blood stream infection and also from the hands of health care providers in the ICU from June 1st to September 30th, 2013.The antibiotic susceptibilities of the Serratia marcescens isolates were tested.PCR was performed to amplify the common drug resistant genes. Pulse-field gel electrophoresis ( PFGE) was carried out for analyzing the homology of all isolates.The com-plete clinical data of the patients were collected and statistically analyzed with Spearman′s rank correlation coefficient.Results Seventeen strains were isolated in this study.All of the 17 strains were resistant to the first and second generation Cephalosporin, Gentamicin and Ciprofloxacin, and sensitive to Amikacin and Ceftazidime.The drug resistant rates to Carbapenems ranged from 11.76%to 35.29%.One of the isolates (5.88%) carried the TEM gene.The results of PFGE showed that the phenotypes of all isolates were identi-cal.Conclusion Serratia marcescens strains were critical hospital infectious pathogens.They were able to spread in the hospital and were resistant to multiple antibiotics.Clinical physicians should properly use anti-biotics for the patients based on the result of drug susceptibility test.A control regulation for Serratia marces-cens infection within hospital should be enforced to avoid the cross infection and the outbreak of resistant strains.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

Objective To investigate the relationship between the ultrasonography diagnosis in prenatal and the postnatal placental vascular casts of the twins reversed arterial perfusion(TRAP) sequence. Methods Six cases of TRAP sequence underwent the two-dimensional and color Doppler ultrasonography, and performed placental vascular casts after termination of pregnance. Results According to the anatomical features and ultrasonography, there were 3 cases of acardius acephalus( IV) ,2 cases of acardius anceps( II ) , and 1 case of acardius acormus( I ). In all 6 cases,there were arterio-arterial and veno-venous anastomoses at the level of the chorionic plate between the normal co-twin and the acardiac twin,these anastmosis vessels were superficial and large calibre, and the distances of the placental insertions of the umbilical cords were different,4 cases <0. 5 cm, 2 cases were 4-5 cm. In 4 cases, the vessels entered and went out of the acardiac twin were just one large umbilical artery and one large umbilical vein. In 2 cases, the umbilical artery and umbilical vein had many vascular branches in the placenta. Out of 6 cases of the pump twin, 4 cases died,and 2 cases survived. Conclusions Ultrasonography was consistent with the placental vascular casts,the contrast observing gives us new information for the further research of the special type of the vascular anastmosis and prognosis of the TRAP sequence.
