As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.

AIM: To isolate peptides targeted binding and internalizing into glioblastoma cell line SWO-38. METHODS: Tumor cells were screened five rounds of whole cell screen through the Ph.D.-12 phage display library. The monoclone specific binding efficiency to the tumor cell was analyzed, and the DNA of phages were extracted, sequenced and translated to the sequences of amino acid. RESULTS: In the phage library after five rounds of screen , 10 of 13 monoclones had highly selective binding to SWO-38 cells. We found two repeated peptide sequences. CONCLUSION: Whole cell screening against tumor cells through random phage peptide library can obtain phage peptides with highly specific binding and internalizing ability. The peptides could be used as a therapy vector for tumor targeted delivery.

Objective To assess circulating miRNAs’diagnosis value of breast cancer.Methods Conducted PubMed,Embase, the Cochrane Library,CNKI,cqvip,and wangfang database search in any language before June 2014.A total of 12 publica-tions were included in the meta-analysis.Then,the meta-analysis was performed using Meta-Disc 1.4.Meanwhile,the diag-nostic sensitivity,specitivity,positive likelyhood ratio,negative likelyhood ratio and diagnostic odds ratio were pooled by ran-dom-effects models.And the overall diagnostic performance was estimated by summary receiver operating characteristic curves (sROC)approaches.Stata12.0 was used to evaluated the publication bias.Results The pooled sensitivity was 80%(95%CI 0.77~0.82),specificity was 78% (95%CI 0.75~0.81);positive likelihood ratio was 4.09 (95%CI 2.80~5.99), negative likelihood ratio was 0.22 (95%CI 0.15~0.31),diagnostic odds rations was 20.64 (95%CI 10.24~41.62).The AUC for circulating miRNAs was 0.89 with Q value of 0.82.Publication bias was observed in existing literatures.Conclu-sion Circulating miRNAs is a potential biomarker in the diagnosis of breast cancer.

Objective To search for an easy standardization p aternity testing method. Methods Based on nine completed da ta and stable tetranucleotide STR loci, 45 paternity cases were typed by using f luorescence labeling primer, multiplex PCR, higher sensitivity 377 DNA sequencer , and then the computer automatically collected the data and made analysis, STR loci alleles and genotypes were determined. Results Th ere was no relationship between alleged fathers and children in 21 cases. But in 24 cases the relationship could not be excluded. Conclusion The STR loci genescan method is convenient, time-saving, fast and has hig her sensitivity. The results are accurate and reliable.

Objective To assess the efficacy of methylprednisolone (MP)pulse therapy in treatment of Hashimoto thyroiditis(HT) complicated with goiter.Methods 30 patients with HT complicated with goiter participated in the study and received MP pulse therapy.The patients had to be euthyroid for at least 3 months before the date of inclusion with plasma concentrations of thyroid hormones within their reference range.The goiter was still obvious and had no improvement.A dose of 250 mg MP was administered intravenously for seven consecutive days,and then treated with oral prednisone 10 mg,three times per day for 6 weeks with the dosage in each week gradually reduced at 5 mg to none.Ultrasonic was used to measure thyroid size before and after MP treatment.Results The treatment was successful at the end of the trial in all of the 30 patients receiving MP.The thyroid size from length,breadth,thickness to isthmus obviously decreased (P ＜ 0.05).The length of the left lobe was (57.42 ± 12.87) mm and (46.37 ± 7.67) mm (t =4.58) before and after treatment; The breadth of the left lobe was(26.68 ±7.71) mm and(22.21 ±6.09) mm(t =4.56) before and after treatment; The thickness of the left lobe was (27.18 ± 6.60) mm and (21.14 ± 5.67) mm(t =7.28) before and after treatment.The length of the right lobe was(58.17 ± 12.32)mm and(49.73 ±9.35) mm(t =3.84) before and after treatment; The breadth of the right lobe was (26.14 ± 7.37)mm and (23.00 ± 6.68) mm(t =3.29) before and after treatment ; The thickness of the right lobe was(27.57 ± 6.42)mm and(22.00 ±5.55)(t =5.88)before and after treatment.The isthmus before and after treatment was(9.94 ±4.15)mm and(6.19 ±2.57)mm(t =6.09).The recurrence rate was 17％ (5/30) after one year.Conclusions MP pulse therapy is an effective treatment for HT complicated with goiter.The recurrence rate is low.

OBJECTIVETo explore the effects of Wenyang Huazhuo Tongluo Recipe (WYHZTLR) containing serum on transforming growth factor β1 (TGF-β1)/Smad signaling pathway of skin fibroblasts in systemic sclerosis (SSc).

METHODSTotally 36 SSc patients were randomly assigned to Chinese medicine (CM) group, Western medicine (WM) group, and integrative medicine (IM) group according to random digit table, 12 in each group. Patients in the CM group took WYHZTLR decoction (one dose per day). Patients in the WM group took penicillamine tablet (0. 125 g each time, bid) and Prednisone Acetate Tablet (PAT 20 mg, qd). Patients in the IM group took penicillamine, PAT, and WYHZTLR decoction (in the same dosage of corresponding drugs as aforesaid). All patients were treated for one month to get drug containing serum. Besides, 10 untreated SSc patients' serum was taken as the control group. Healthy subjects' skin fibroblasts were originated from healthy skin tissue of the upper arms of 2 female patients undergoing plastic surgery. Corresponding serum of each group was added in the culture system of SSc patients' and healthy subjects' dermal fibroblasts respectively. Expression levels of TGF-β1 receptor type I (TGF-β1 RI), TGF-β1 receptor II (TGF-β1 RII), p-Smad2/3 and Smad7 protein were examined by Western blot. Expression levels of collagen type I and collagen type III (Col-I, Col-III) mRNA were examined by reverse transcription PCR. Contents of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) in the supernatant of SSc, skin fibroblasts were examined by ELISA.

RESULTSCompared with the control group, expression levels of TGF-β1 R I and p-Smad2/3 protein significantly decreased, but expression levels of Smad7 protein significantly increased in skin fibroblasts of SSc patients and healthy subjects of WM, CM, and IM groups (P <0.05, P <0. 01). Meanwhile, the expression level of TGF-β1 RII decreased in the IM group (P <0. 05, P <0. 01). Compared with the WM group, expression levels of TGF-β1 RI and p-Smad2/ 3 protein significantly decreased, but that of Srnad7 protein significantly increased in IM groups (P <0. 01). mRNA expression levels of Col-I and Col-II in SSc skin fibroblasts significantly decreased more in WM, CM, and IM groups than in the control group (P <0. 05, P <0. 01). Besides, the expression level of Col-III mRNA was significantly lower in the IM group than in the WM group (P <0.01). Compared with the control group, serum levels of MMP-9 and MMP-9/TIMP-1 ratios increased more obviously in WM, CM, and IM groups (P <0.05, P <0.01). But expression levels of TIMP-1 decreased significantly in CM and IM groups (P <0.01). Expression levels of MMP-9 and MMP-9/TIMP-1 ratios increased more in the IM group than in the WM group (P <0. 01). Expression levels of TIMP-1 decreased more in CM and IM groups than in the WM group (P <0.01).

CONCLUSIONWYHZTLR containing serum could reduce expression levels of Col-I and Col-III possibly through regulating key signal molecules, such as TGF-β1 RI, p-Smad2/3, and Smad7 in TGF-β1/Smad signaling pathway of SSc skin fibroblasts, and inhibiting transduction of TGF-β1/Smad signaling pathway.
