Lymph nodes (LN)are the main parts of the esophageal cancer metastasis,and the current status of LN is the important indicator of prognosis.LN metastasis appears in early stage of esophageal cancer.One side,LN metastasis easily appears in the regions near the tumor and some special areas.On the other side,LN metastasis has the characteristics of wide metastasis and skip metastasis.Therefore,the researches of the pattern of esophageal cancer lymph node metastasis can help to comform the scope of the esophageal cancer lymph node dissection and the target regions of radiotherapy.

Post management should replace capacity management in the reform of the personnel system in the health sector. The authors expound in the first place the connotations and the necessity of post management, and then discuss respectively three key links, viz. change of ideological concepts of people at various levels in the implementation of post management; establishment of necessary setups and mechanisms for post management; and organic combination of responsibilities, powers and interests in post management. Finally the authors put forward the following viewpoints in light of Tongren Hospital's practice in adopting post management: ①setting up a primary personnel system based on double engagements; ②setting up a system of selecting key members for posts based on a mechanism of post reward, such as the classification of chief experts into three classes; ③setting up a managerial mechanism conducive to the rational flow of personnel; ④conducting checks so as to provide basis for distributing appropriate salaries, with the elements of management, expertise and responsibilities taken into consideration in the distribution. The effects are also discussed.

Objective To evaluate the clinical significance of the multiple cytokines in the serum of SARS patients and explore the rel ationship between the immune-reactivity and pathological damages. Methods 12 different serum cytokines have been detected in 4 groups ( inchoation, metaphase, convalescence of SARS patients and Healthy control) by using biochips technique(RANDOX) and to study the changes of each cytokine level in SARS patients. Results Compared with healthy group, IL-6 , IL-8 , IL-10 ,IFN? increased obviously and IL-1? ,IL-2,IL-4,VEGF,EGF,MCP-1, TNF?decreased obviously. Whereas IL-1?has no statistic changes among different stages of SARS. Conclusion There were obvious changes of multiple cytokines in different phase of SARS pathological process, especially in the early phase. It is further support the hypothesis that over-reaction of the immune system initiated the pathological injuries of the patients.

Objective To detect the change of serum cystatine C ( cys C ) level in Parkinson ’ s disease ( PD ) patients with obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and explore its influencing factors .Methods Fifty-six PD patients with polysomnography examination from July 2011 to December 2013 in the Department of Neurology , the Second Affiliated Hospital of Soochow University were collected.Eighteen healthy controls who took the polysomnography examination during the same period were included.According to the apnea-hypopnea index ( AHI) , PD patients were further divided into two groups:PD with OSAHS group ( n=26 ) , and PD group ( n=30 ).The general conditions , movement function , biochemistry parameters , and sleep parameters were assessed.Statistical analysis was performed using SPSS ver 17.0 software.Results The mean serum levels of cys C in PD with OSAHS group , PD group and control group were (1.05 ±0.17) mg/L, (0.96 ±0.12) mg/L and (0.84 ±0.20) mg/L, respectively.Statistical analysis showed that there was significant difference in the three groups (F=9.184,P<0.05), and the mean serum level of cys C in PD with OSAHS group was the highest.In PD with OSAHS group , Spearman correlation analysis showed a positive and significant correlation between cys C levels and creatinine levels (r=0.459,P =0.018), urea levels (r =0.405,P =0.040), AHI (r =0.482,P =0.013), the oxygen desaturation index (r=0.408,P=0.038), the arousal index (r=0.392,P=0.047) as well as Hoehn and Yahr (H-Y) stage (r=0.467,P=0.016).Correlation was not observed between cys C levels and other clinical parameters (P>0.05).Multivariate analysis showed that creatinine levels (B=0.007,P=0.005), AHI (B=0.004,P=0.013) , H-Y stage (B=0.102,P=0.026) may be influencing factors of cys C levels in PD patients (P<0.05).Conclusions Cys C level is elevated in PD patients, especially in PD patients with OSAHS.The degree of hypoxia and severity of PD is related to the level of cys C in PD patients with OSAHS .

Objective:To analyze the characteristics of regional lymph node metastasis in patients with resectable non-small cell lung cancer (NSCLC) and assess its clinical significance in surgical mediastinal lymph dissection and the target volume definition of postoperative radiotherapy. Methods:We retrospectively reviewed 810 patients with NSCLC, and analyzed the metastatic frequency of each regional lymph node station as well as the correlation between tumor location and regional lymph node metastases. Results:Re-gional lymph node metastases were significantly associated with the age of patients, histology, tumor size, and tumor location (P=0.013, 0.000, 0.009 and 0.000, respectively). Conclusion:The younger patients with left lung adenocarcinomas and large tumor size tended to regional lymph node metastases. The trend of regional lymphatic drainage in the lobes of lung occurred differently. The prior location of involved regional lymph nodes in different lobes of the NSCLC patients was as follows:The station 2-4 for right upper lobe tumors, the station 2-4 and 7 for right middle lobe tumors and right lower lobe tumors, the station 5-6 for left upper lobe tumors, and the station 5-6 and 7 for left lower lobe tumors. We should pay more attention to the regions regarding the higher frequencies of lymph node metastases, when determining the extent of lymph node dissection or delineating the target volume of postoperative radiotherapy for NSCLC patients.

Objective To explore the clinical efficacy of nibble debridement combined with silver ions dressing in treatment of diabetic foot ulcer.Methods The data of 238 patients with diabetic foot ulcer in people's hospital of Meishan from January 2012 to December 2016 were retrospectively analyzed.Of which 125 patients were treated by nibble debridement combined with silver ions dressing(nibble debridement group),113 patients were treated with surgical debridement combined with silver ions dressing(surgical debridement group).The clinical efficacy,wound healing time and complication between two groups were compared.Results The wound healing time of nibble debridement group was (37.5 ± 10.8) days,which was shorter than (45.3 ± 11.7) days of surgical debridement group,the difference was significant (P ＜0.05).The total effective rate of nibble debridement group was 92.80％,which was higher than 73.45％ of surgical debridement group,the difference was significant(P ＜ 0.05).No complication occurred in two groups.Conclusion The method of nibble debridement combined with silver ions dressing treatment has a better satisfactory clinical result,shorter wound healing time and lower medical costs for patients with diabetic foot ulcer.

Objective To explore the specific role of autophagy and ubiquitin-proteasome pathway in apoptosis, specific protease inhibitor and (or) macroautophagy inhibitors.Methods The stimulators were selected to work on the pheochromocytoma (PC12) cell lines transfected with human mutant α-synuclein (A53T).Cell activity and apeptosis rate were detected by MTT law and flow cytometry.NO energy, heat shock protein 70 (Hsp70) and Caspase-3 expression were determined in cell culture.Results A53T cell survival rate significantly decreased 24 hours after handling with the protease inhibitor (100 nmol/L) and (or) autophagy inhibitors 3-MA (10 mmol/L, A =0.23±0.01,0.19±0.01 and 0.17±0.01 respectively; P <0.05) compared with the control group (A =0.32±0.06).Cell survival rate was significantly higher than the other drug group after 24 hours handling with autophagy stimulators (A =0.44±0.08).Compared with the control group or autophagy stimulator of rapamycin (0.2 μg/ml) group (1.55%±1.15%), A53T cells apeptosis percentage rate was significantly higher after treated with proteasome inhibitor and macroautophagy inhibitors 24 hours (4.74%±0.91%, 4.59%±1.18% and 5.40%±1.75%respectively, P <0.05); and a slight decrease with stimulators.Protein Hsp70 and NO were significantly higher in proteasome inhibitor groups than the control group.But in antophagy inhibitor and stimulator group, NO and Hsp70 protein was similar to the control group.Conclusion The inhibition of macroautophagy and proteasome can promote apoptosis.Inhibiting or stimulating autophagy has less impact on Hsp70 and NO than proteasome pathway.

Objective To evaluate the outcome of radiotherapy for recurrent esophageal cancer after surgery and to determine the prognostic factors. Methods From Jan 2004 to Dec 2009, 93 patients of esophageal carcinoma with loco-regional recurrence as the first site of failure after surgery were retrospectively reviewed. Kaplan-Meier method was used to analyze the survival. Logrank test was used to evaluate the difference between the groups. Multivariate survival analysis was conducted using a Cox proportional hazard regression model with a backward stepwise procedure. Results The overall survival rates at 1, 2 and 3 years were 40. 9% , 10. 1% and 6. 7% ,respectively,but with a median survival time of 11.0 months(95% CI 9. 4-12. 6) . In univariate analysis, age,PS, radiation dose and retreatment methods were independent prognostic factors. In multivariate analysis, only radiation dose and retreatment methods were independent prognostic factors for overall survival. Conclusions The prognosis of patients with postoperative loco-regional recurrence of esophageal cancer is poor. However, a long-term survival maybe expected by definitive chemoradiotherapy.

Objective To explore the distribution characteristics of ankle-brachial index ( ABI) examination for peripheral arterial dis-ease in diabetic patients, and to provide basis for clinical diagnosis. Methods Randomly selected 110 cases of patients who were admitted into our hospital from February 2014 to January 2015, and divided them into the observation group (34 cases with diabetic lower extremity peripheral vascular lesions) and the control group (76 cases without diabetic lower extremity peripheral vascular lesions). Measured the ABI of the two groups, and analyzed the value of ABI data range for the diagnosis of diabetic lower extremity peripheral vascular lesions. Mean-while, analyzed the risk factors of peripheral arterial disease in diabetic patients according to ABI. Results The sensitivity of ABI for diag-nosis of diabetic lower extremity peripheral vascular lesions was 91. 18%, and the coincidence rate was 95. 36%, the specificity was 98. 68%, the misdiagnosis rate was 8. 82%, and the omission diagnostic rate was 8. 82%. ABI of the observation group was obviously lower than that of the control group, and the difference was statistically significant (P<0. 05). Conclusion ABI examination could be basis of clinical diagnosis and important standard of disease assessment for peripheral arterial disease in diabetic patients. It is suggested to strengthen the control of blood glucose, blood pressure and weight of patients with diabetes in order to reduce the risk of morbidity.
