Supported by various departments concerned of the district government, medical workers in Luwan District of Shanghai started in 1994 to set up in the whole district community based social help network for the medical care of SCGFD. In the last 4 years, the annual outpatient volume of SCGFD averaged 3.9 times and the annual visits received by SCGFD averaged 2.2 times. The conditions of 78.1% of SCGFD suffering from an illness turned for the better or became stable. The annual hospitalization utilization ratio averaged 5.4%. After hospitalization, 89.5% of SCGFD suffering from a serious illness fully recovered from their illness or were discharged after turning for the better. The average outpatient expenses per time, hospitalization expenses per day and per time of SCGFD respectively dropped 32.1%, 21.5% and 30.4%, as compared with the group of senior citizens enjoying free medical care. The authors hold that the social help network for the medical care of SCGFD in Luwan District is an easy to operate and effective community based medical security system for SCGFD. It has produced sound social repercussions after being put into practice. The controlled use of medical funds has ensured the normal operation of the network.

Objective To evaluate the performance of ultrasonography (US) for the preoperative staging of papillary thyroid carcinoma (PTC). Methods One hundred and twenty-one patients with cytologically proven PTC were prospectively collected. Patients were recruited at the Chinese Academy of Medical Sciences Cancer Hospital from January 2014 to November 2014. Preoperative US was performed for the evaluation of primary tumor size, extrathyroidal extension and neck lymph node metastasis according to the 6th UICC TNM staging system. Results The sensitivity, specificity, positive predictive value (PPV) and negative predicative value (NPV) of US in predicting extrathyroidal extension were 89.6%(60/67), 72.2%(39/54), 80.0%(60/75), 84.8%(39/46), respectively. The accuracies of preoperative US for T1, T2, T3, T4 stage were 75.0%(36/48), 100%(1/1), 81.9%(59/72), 0, respectively. The sensitivity, specificity, PPV, and NPV of US in predicting neck lymph node metastasis were 47.5%(29/61), 90.0%(54/60), 82.9%(29/35), 62.8%(54/86), respectively. Conclusion Ultrasonography is a feasible tool for preoperative staging of PTC and is helpful for accurate prediction of extrathyroidal tumor extension and lateral neck lymph node metastasis.

Objective To evaluate the role of endorectal ultrasonography with coupling gel intrarectal filling in preoperative T stage of rectal cancer. Methods One hundred and fifteen patients with rectal cancer underwent endorectal ultrasonography with coupling gel intrarectal filling. The preoperative T stage according to ultrasonic manifestations was compared with histological findings. Results The total diagnostic accordance rate of preoperative T stage by endorectal ultrasonography with coupling gel intrarectal filling was 89.57%. The sensitivity of ultrasonography for T1, T2, T3 and T4 was 93.10%, 61.11%, 96.61%, 88.89%, while the specificity was 97.67%, 96.91%, 89.29%, 99.06%, respectively. The overstaging rate of ultrasonography was 6.96% (8/115), and the understaging rate was 3.48% (4/115). Conclusion Endorectal ultrasonography with coupling gel intrarectal filling is a valuable diagnostic method for T stage of rectal cancer.

Objective:To explore the effect of revision endoscopic sinus surgery (RESS) on quality of life in the patients with chronic rhinosinusitis with nasal polypsis (CRSwNP).Method:To survey and evaluate 60 cases of RESS patiens (treatment group) and 120 normal ones with physical examination (Control group) through the medical outcomes survey short form questions (MOS SF-36) and the Sino-Nasal Outcome Test-20 (SNOT-20), and comparison and analysis of the two groups results which we got were carried out.Result:With SF-36 scales for evaluation of quality of life, the results show that: the scores of CRSwNP patients (treatment group) without surgical treatments with RESS were significantly lower than that of the control group(P<0.05); while use of SNOT-20 scales in evaluation of the properative treatment group patients, the results were significantly higher than that of the control group(P<0.05). While the CRSwNP patients with surgical treatments with RESS for 6 monthes, not only with SF-36 scales but also with SNOT-20 scales,there was no significant difference between the two groups(P>0.05 ).Conclusion:RESS may obviously improve the clinical symptom of CRSNP patients. The SF-36 and SNOT-20 assessment scales could reflect the patient's QoL change.

Objective To evaluate the respiration-induced dosimetric variance in 3DCRT for midthoracic esophageal carcinoma, in order to guide the radiation oncologist to choose the expansion margin. Methods Ten patients with mid-thoracic esophageal carcinoma were scanned by multi-spiral CT simulator respectively in free breathing ( FB), breath-hold after normal inspiration and expiration ( IBH and EBH )with the same scanning range. Then the CT images of three series were transferred to the treatment planning system. The target volume was outlined following the same standard. Plan1 was designed in the images of FB and transported completely to the images of IBH and EBH as Plan2 and Plan3 respectively to observe the dosimetric variance in target volume. Results For GTV, there was a statistical difference only in V100 of the three plans ( H = 6.423, P = 0.040 ) and no significant difference was found in other indexes. For CTV, the V100 and V95 were better in Plan1 (F=3.992, P=0.030; H=9.920, P=0.007) and no significant difference was found in other indexes. While ()TV, the Dmin, V100 and V95 was better in Plan1 ( F = 3.677, P = 0.039; F = 4.539, P = 0.020; H = 6.846, P = 0.033 ) and no significant difference was found in other indexes. There were no significant differences in all the indexes for the spinal cord and lung in the three plans. Conclusions The change in dose distribution was not so much with the standard expansion. It can meet the needs of clinical treatment.

Objective To investigate the therapeutic effects,adverse effects,and patterns of failure of elective irradiation of lymphatic drainage area (extended-field) and involved-field irradiation in three-dimensional radiotherapy (3DRT) in patients with esophageal cancer via a Meta-analysis.Methods The databases Wanfang Data,CNKI,VIP,CBM,PubMed,Embase,and Cochrane Library were searched to collect the controlled clinical trials on extended-field irradiation and involved-field irradiation in 3DRT in patients with esophageal cancer.Stata 11.0 was used for data analysis.The odds ratio (OR) with 95％ confidence interval was used to describe the differences between two groups.Results According to the inclusion and exclusion criteria,a total of 12 controlled clinical trials involving 1 095 patients with esophageal cancer were included in this meta-analysis.The results of the meta-analysis showed that compared with the involved-field irradiation group,the extended-field irradiation group had a significantly reduced rate of out-field failure in patients with esophageal cancer who received 3DRT (OR=3.727,P=0.007),but showed significantly higher rates of grade ≥ 3 acute radiation pneumonitis and radiation esophagitis (acute radiation pneumonitis:OR =0.348,P =0.001;radiation esophagitis:OR =0.385,P =0.000).The two groups had similar 1-,2-,and 3-year local control rate and overall survival rate (local control rate:OR=0.966/0.946/0.732,P=0.837/0.781/0.098;overall survival rate:OR=0.952/1.149/0.768,P=0.756/0.422/0.120),as well as a similar distant metastasis rate (OR=0.986,P=0.937).Conclusions Compared with involved-field irradiation,extended-field irradiation can reduce the rate of out-field failure in patients with esophageal cancer who receive 3DRT.However,it does not have significant advantages in local control rate and overall survival rate and has an increased incidence rate of adverse effects.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.
