Objective To observe the oncololigcal and cosmetic outcomes and complication of breastconserving surgery and radiotherapy for early breast cancer. Methods A total of 78 early breast cancer patients, who were treated in the First People's Hospital of Pingdingshan between January 2001 and September 2008, were identified and followed. Among them, 36 were in stage Ⅰ and 42 in stage Ⅱ. Tangential irradiation was used with a dose of 50 Gy. Tumor bed received a boost dose of 10 Gy electron beam. For axillary lymph node-positive patients, ipsilateral supraclavicular field was hybrid irradiated with 50 Gy X and electron beam.Results The total follow-up ranged from 6 to 98 months. Local recurrence was observed among 4.9% of the patients. The 3-year and 5-year overall survival rate were 96.6% and 92.7% ,respectively. The breast cosmetic satisfaction rate was 94.9%. The main complications reported were acute skin reaction and upper limb edema.Conclusion Breast-conserving surgery and post-operative radiotherapy in early breast cancer patients can lead to satisfactory survival rates and cosmetic effects and hence improved life quality.

AIM:To investigate the value of pattern visual evoked potential (PVEP) and flash electroretinogram (FERG) in early diagnosis and prevention of diabetic retinopathy (DR), analyzing the correlation of early stage DR with PVEP and FERG.
METHODS: Sixty patients, 30 males and 30 females, participated in observation group. Their average age was 19. 42 ± 7. 78years. The duration of DM was < 5a. Best corrected visual acuity was 5. 0. Fasting blood glucose was 7. 8± 3. 6mmol/ L. There were 60 subjects, 30 males and 30 females, in control group. Their average age was 17. 2 ± 6. 52years. Best corrected visual acuity was 5. 0. Every participator was tested with PVEP and FERG according to ISCVE standard. The amplitude of PVEP and P100 latency were recorded. And the b-wave latency, b-wave amplitude, a - wave latency, a - wave amplitude were showed down.
RESULTS: In observation group, P100 amplitude decreased and P100 latency increased, compared to those of control group ( P< 0. 01); b - wave latency, b -wave amplitude, a - wave latency, a - wave amplitude were different from those in control group(P<0. 01); the fasting blood glucose kept stable; P100 amplitude, b -wave amplitude and a-wave amplitude were not related to the DM duration; P100 latency, a-wave latency and b-wave latency were related to the DM duration.
CONCLUSION: PVEP are sensitive to optic neuron damage; FERG is desirable to detect the lesion of Müller cells and bipolar cells. P100 amplitude by PVEP, b-wave amplitude by FERG may be the most sensitive parameter for DR at early stage.

Objective In clinical practice,ultrasound-guided fine-needle aspiration biopsy (US-G FNAB) is the gold standard in diagnosing the pathological nature of undetermined thyroid nodules before operation.Re---sults of FNAB may vary substantially among operators with different skills.The aim of this study is to evaluate whether operator experience in US-G FNAB influences the rate of diagnostic procedures.Methods A total of 600 consecutive US-guided FNAB done by a single radiologist with 22-or 27-gauge needles from Feb.2008 to Apr.2012 were retrospectively analyzed.All specimens were prepared and fixed without the cytologist on site and were subsequently analyzed by 2 expert cytologists.The procedures were chronologically divided into 6 groups and further stratified according to the overall (A),solid nodules (B),mixed nodules (C),pure cystic nodules (D),acellular sample(E),heavily blood-stained sample(F),exclusively colloid material(G),incorrect slide fixation(H) and they were classified as diagnostic or no-diagnostic.Results The rate of no-diagnostic procedures for each group in learning curves were reported as:① Among A,34％ in group 1,15％ in group 2,18％in group 3,10％ in group 4,7％ in group 5,and 8％ in group 6.② Among B,4％ in group 1,1％ in group 2,0％ in group 3,0％ in group 4,0％ in group 5,and 0％ in group 6.② Among C,10％ in group 1,1％ in group 2,4％ in group 3,0％ in group 4,1％ in group 5,and 0％ in group 6.④ Among D,20％ in group 1,13％ in group 2,14％ in group 3,10％ in group 4,6％ in group 5,and 8％ in group 6.⑤ Among E,25％ in group 1,15％ in group 2,15％ in group 3,10％ in group 4,6％ in group 5,and 8％ in group 6.⑥ Among F,4％ in group 1,0％ in group 2,1％ in group 3,0％ in group 4,0％ in group 5,and 0％ in group 6.⑦ Among G,1％ in group 1,0％ in group 2,1％ in group 3,0％ in group 4,1％ in group 5,and 0％ in group 6.⑧ Among H,4％ in group 1,0％ in group 2,1％ in group 3,0％ in group 4,0％ in group 5,and 0％ in group 6.Among the 600 procedures,there were 2 cases of vertigo and 4 cases of moderate bleeding at the biopsy site,all of which resolved spontaneously.No major complications were recorded.Conclusions The rate of no-diagnostic US-guided FNAB is heavily dependent on the operator's experience.We estimate that at least 200 procedures are needed in order to achieve the levels of diagnostic accuracy reported in the literature.We therefore suggest operators to get specific training before routinely perform this procedure in clinical practice.

Quantitative proteomics is a novel subject of proteomics research. There are several new techniques employed for the protein quantitative study. Isobaric tags for relative and absolute quantitation (iTRAQ) technology for protein quantitation using mass spectrometry is a recent powerful means of determining relative and absolute protein levels in up to four samples simultaneously. The iTRAQ reagent produced high quality, reproducible result in enriched complexes, organelles, and whole cell lysates. The status of the recent promising techniques and their possible future evolution were reviewed.

Objective To explore the value of plasma C-peptide levels in early prediction of type 2 diabetes mellitus with peripheral sensory neuropathy.Methods The vibration perception threshold,pain,temperature sensation,touch-pressure sensation,ankle reflex was detected in 500 eases of type 2 diabetes mellitus,and the patients were divided into 4 groups according to peripheral sensory nerve test results:normal group (159 cases),mildly abnormal group (120 cases),moderately abnormal group (121 cases) and severely abnormal group (100 cases).Fasting and 2-hour postprandial C-peptide levels were determined and analysed with peripheral sensory nerve changes.The receiver-operating characteristic (ROC) curve was used to find the best critical point for diagnosis of diabetic peripheral sensory neuropathy.Results The fasting C-peptide among 4 groups had no significant difference (F =1.632,P ＞0.05).Two-hour postprandial C-peptide from normal group to mildly abnormal group and then moderately abnormal group gradually increased [(1.110 ± 0.526),(1.324 ± 0.490),(1.573 ± 0.716) μ g/L],while 2-hour postprandial C-peptide in severely abnormal group was significantly decreased and lower than that in normal group,and there were significant differences (P＜ 0.05).The max Youden Index was 0.366 when 2-hour postprandial C-peptide was 1.173 μ g/L.Conclusions The fasting C-peptide might be not related to early diabetic peripheral sensory neuropathy,but 2-hour postprandial C-peptide might be closely related to early diabetic peripheral sensory neuropathy.It is helpful to detect the early diabetic peripheral sensory neuropathy if we can take a dynamical observation of 2-hour postprandial C-peptide.
