Objective To explore differential expression of protiens between patients with esophageal cancer and healthy individuals, and to screen out the tumor biomarkers to construct a dignostic model. Methods From January to August, 2008, the clinical data of 127 patients with esophageal cancer (esophageal cancer group) who had been admitted to the First Affiliated Hospital of Xinjiang Medical University and 63 healthy individuals (control group) were retrospectively analyzed. The serum proteomic profiles of the esophageal cancer pateints and healthy individuals were deteced by weak cation exchange and hydrophobic surface ProteinChip using the surface enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDT-TOF-MS) technique.Serum differentially expressed markers of esophageal cancer were screened out to establish the diagnostic model for esophageal cancer. All data were analyzed using rank sum test. Results Six proteins were high-expressed in the esophageal cancer group, and the mass-to-charge ratios were 4488, 5495, 15964, 3948, 8154, 8166. Four were low-expressed in esophageal cancer group, and the mass-to-charge ratios were 8789, 6682, 8714, 6650. A diagnostic model consisting six proteins was established. A total of 124 patients were correctly diagnosed and three were misdiagnosed in the esophageal cancer group, and 60 were correctly diagnosed and three were misdiagnosed in the control group. The accuracy, sensitivity and specificity of the diagnostic model were 96.8% ( 184/190),97.6% ( 124/127 ) and 95.2% (60/63). Conclusions The diagnostic model established based on the tumor markers screened out by the SELDT-TOF-MS is highly sensitive and specific.

Objective To investigate clinical presentations,laboratory examinations,magnetic resonance imaging (MRI) appearances and treatment of hypertrophic cranial pachymeningitis (HCP).Methods The clinical data of 13 patients with HCP receiving comprehensive therapy in Huashan Hospital from January 2007 to January 2013 were analyzed retrospectively.Results The onset of HCP was mostly chronic with an average duration of 26.7 months.The main clinical manifestations of the 13 patients were chronic headaches (12/13) and cranial nerve paralysis (12/13).Inflammation markers and cerebro-spinal fluid (CSF) protein levels increased in patients with HCP and gradually became normal after the treatment.The MRI demonstrated local or diffused thickened dura located in tentorium (10/13),falx cerebrum (5/13),frontal lobe (4/13),temporal lobe (7/13) and parietal lobe (4/13).The signal intensity was isointense on T1-weighted MR images and hypointense on T2-weighted MR images.Enhanced MR images showed conspicuous enhancement of the dural edges.Corticosteroid therapy improved the clinical symptoms in 12 of 13 patients.Conclusions HCP typically causes headache and paralysis of multiple cranial nerves.Enhanced MRI shows characteristic manifestations.At present corticosteroid therapy is the treatment of choice followed by immunosuppressive agent and radiotherapy.

As the complexity of samples and experimental processes, the repeatability of mass spectrometry experiments is still not satisfactory, the results of peptide identification and quantification show high randomicity), the probability of peptide being detected by mass spectrometry in proteome research, especially in quantitative proteomic study, has received much attention. Therefore, a lot of experimental researches have been done, as well as a number of computational prediction methods have been developed. In this article, we summarized the important factors impacting the peptide detectability, investigated the existing prediction methods) and reviewed their applications in experimental study.

Objective To investigate the effects of reducing the auditory organ dose by limitation of sub regional auditory organ in IMRT plan. Methods Total 223 cases of nasopharyngeal carcinoma patients were divided into group A and group B. In group A, the IMRT plans of 114 patients were designed by limiting overall auditory organ dose. In group B, the IMRT plans of 109 patients were designed by limiting sub regional auditory organ dose. According to the Clinical prescription, the IMRT plans were designed. Paried t?test was difference between groups. Results By comparing the two groups of auditory organ dose, in all stages, the tympanic cavity Dmean average in group B decreased by T1 vs. 17?? 7%,T2 vs. 22?? 4%,T3 vs. 15?? 7% and T4 vs. 14?? 2% ( P= 0?? 000,0?? 000,0?? 000,0?? 000);cochlea Dmean average decreased by T1 vs. 11?? 0%, T2 vs. 20?? 1%, T3 vs. 10?? 0% and T4 vs. 9?? 0%(P= 0?? 004,0?? 000,0?? 007,0?? 036);vestibule Dmean average decreased by T1 vs. 22?? 6%, T2 vs. 31?? 8%, T3 vs. 20?? 6% and T4 vs. 21?? 4%, significantly less than in group A (P= 0?? 000,0?? 000,0?? 000,0?? 000). The bony portion of eustachian tube Dmean average in group B decreased were not significantly less than in group A (decreased by 3?? 4%,6?? 8%,3?? 6%,0?? 1%;P= 0?? 291, 0?? 006,0?? 155,0?? 963). Conclusions In IMRT plan, optimization on dose limitation of sub regional auditory organs were used to reduce the auditory organ dose and decrease the radiation damage to auditory organ.

Objective To evaluate clinical features,therapeutic effects and outcomes of patients with non-human immunodeficiency virus(HIV)-infected cryptococcal meningitis treated with fluconazole or fluconazole and flucytosine.Methods Twenty-four cases of non-HIV-infected cryptococcal meningitis(fluconazole with or without flucytosine as initial therapy)in Huashan Hospital,Fudan University from 1997 to 2007 were retrospectively reviewed.Clinical manifestations,therapeutic effects and outcomes of the patients were collected.Results Fluconazole was administered with median dosage of 400 mg/d,for a median duration of 20.5 days.After fluconazole initial therapy for 2 weeks,16.7% showed partial response,83.3% showed no response,and the overall response rate was 16.7%.After 10 weeks,33.3% showed partial response,29.2% showed complete response,16.7% showed no response,and the overall response rate was 62.5%.Mortality at week 10 was 20.8%.Twenty-two patients who failed to respond to initial therapy were switched to other antifungal drugs(amphotericin B,amphotericin B colloidal dispersion,itraconazole)or other fluconazole containing combined therapy.Eleven out of the 24 patients died during one-year follow-up,8 of whom died of eryptococcal meningitis,and 3 died of other diseases.Conclusions The initial therapy of fluconazole with or without flucytosine is inefficient,and most of the patients need other antifungal drugs because of initial therapy failure.Therefore,fluconazole might not be appropriate for initial therapy in non-HIV-infected cryptococcal meningitis.

VP1 gene encoded by the newly identified caprine enterovirus CEV-JL 14 was amplified and cloned to prokaryotic expression vector pGEX-4T-1.Recombinant GST-VP1 fusion protein was expressed,purified,emulsified with Freund's complete adjuvant and used to immunize the BALB/c mice following a standard procedure.The spleen cells from immunized mice were collected and fused with myeloma cells after its antibody titer reached over 104 times detected by indirect ELISA.Hybridoma cell clones secreting monoclonal antibodies against VP1 were screened and their stability and specificity were further determined.The identified hybridoma cells were injected to mice intraperitoneally and ascites were collected at 7 DPI.Isotypes of the monoclonal antibodies against the recombinant VP1 protein were characterized to be either IgG1 or IgG2b,which showed a high specificity for detection of caprine enterovirus antigens by immunoperoxidase monolayer assay,thus laying a solid basis for future study related to viral pathogenesis,detection and diagnostics for caprine enterovirus infection.

Objective To investigate the predictive value of depth of invasion (DOI) of tongue squamous cell carcinoma (TSCC) for cervical lymph node metastasis and prognosis. Methods We retrospectively analyzed the clinical and pathological data of 73 patients with T_1/2 TSCC. ROC curve was used to determine the optimal cut-off value of DOI for predicting cervical lymph node metastasis, and logistic regression analysis was performed to analyze the related factors affecting cervical lymph node metastasis of TSCC. Kaplan-Meier method and Cox regression analysis were used for survival analysis. Results Among 73 patients, 18 patients were with lymph node metastasis and 55 patients were without lymph node metastasis. The median DOI with and without lymph node metastasis were 8.00 and 5.00 mm, respectively (P=0.003). The optimal cut-off value for DOI was 6.15 mm, with AUC 0.75 (95%CI: 64.1%~87.1%, P=0.001), sensitivity 77.8% and specificity 63.6%. DOI and pathological differentiation were independent prognostic factors for cervical lymph node metastasis in multivariate analysis. DOI, nerve invasion and pathological differentiation were independent prognostic factors of survival in Cox regression analysis. Conclusion DOI of TSCC patients has important predictive value for both cervical lymph node metastasis and prognosis. Neck lymph node dissection is recommended for patients with DOI > 6.15 mm to improve survival rate and reduce recurrence rate.

BACKGROUNDReconstruction of carina, bronchoplasty and arterioplasty are widely used to extend the indication of lung cancer operation. Because these procedures preserve as many healthy lung tissues as possible, their therapeutic effect is better than pneumonectomy in many central lung cancer cases with poor cardiopulmonary function. The aim of this study is to explore the feasibility and indication of extended resection in selected patients with centrally located lung cancer.

METHODSFrom November, 1979 to January, 2003, lobectomy or pneumonectomy combined with extended resection of tracheo-carina, bronchus or vessels were performed in 50 patients with centrally located lung cancer. Tracheo-carinal reconstruction and bronchoplasty were performed in 48 cases, and pulmonary arterioplasty in 2 cases.

RESULTSPostoperative complications occurred in 4 patients (8.0%), and operative death occurred in 2 patients (4.0%). All the 48 patients were followed up from 1 to 10 years. The 1-, 3-, 5- and 10-year survival rate was 89.4% (42/47), 57.1% (20/35), 42.1% (8/19) and 25.0%(2/8) respectively.

CONCLUSIONSExtended pulmonary resection combined with tracheo-carinal reconstruction, bronchoplasty and vascular reconstruction is feasible for selected patients with centrally located lung cancer. It is helpful to prolong the long-term survival of patients with lung cancer.
