0.05. Conclusions Radical nephrectomy remains the cardinal method for the treatment of primary renal cell carcinoma. Extensive retroperitoneal lymphadenectomy does not improve the survival.

ObjectiveTo study the diagnosis and therapy of circumcaval ureter.MethodsFifteen cases of circumcaval ureter were studied retrospectively.The cardinal symptoms include discomfort over the back and loins,nephrocolic and bloody urine.The diagnosis mainly depends on IVU and retrograde urography.12 patients underwent ureteroureterostomy,2 ureteropyeloneostomy and 1 nephrectomy.ResultsAll the patients have been follewed up from 1 to 15 years by IVU and ultrasonography,and no nephrohydrosis or stenosis of the anastomosis site has been noted.All the patients have been free from any complaints.ConclusionsIVU and retrograde urography are the cardinal means for the diagnosis of circumcaval ureter,and operation is indicated in order to improve the renal function.It is important to choose a proper time and an adequate surgical technique.

Objective To investigate the impact of relevant factors in mechanical ventilation on intraabdominal pressure in patients with ALI/ARDS by continuous monitoring of intra-abdominal pressure.Methods A total of 116 ALI/ARDS patients treated with mechanical ventilation in ICU were enrolled in this study.Intra-abdominal pressure (IAP) was recorded continuously.Meanwhile ventilator parameters, arterial blood gas analysis, hemodynamic variables, and as well as the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid (BALF) were determined and recorded.The detection of risk factors for intra-abdomen hypertension (IAH) were carried out using multivariate stepwise logistic regression.ROC curve analysis used to estimate the diagnostic performance of these parameters for IAH.Results The oxygenation index (PaO2/FiO2) in patients with IAH after 2 hours' mechanical ventilation was significantly lower than that in patients with normal intra-abdomen pressure (IAP) (P ＜ 0.01);PEEP and RR in mechanical ventilation were higher in IAH group (P ＜ 0.01 or P =0.001);Mean artery pressure (MAP), ejection time percent (ET), stroke volume (SV), cardiac index (CI) were lower in IAH group than those in normal IAP group (P ＜ 0.01);the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid were higher in IAH group than those in normal IAP group (P ＜ 0.01);IAH patients have a higher mortality on 28 d (Log rank test, P =0.023).Poor oxygenation index (PaO2/ FiO2) after 2 hours' ventilation, high PEEP setting, low MAP, ET, SV, CI and elevated IL-4 in the BALF were resulted in increasing risk of IAH for ARDS patients under mechanical ventilation support.Conclusions The monitoring of intra-abdominal pressure should be emphasized for ALI/ARDS patients when mechanical ventilation was employed.PaO2/FiO2, SV and IL-4 in BALF might be the independent risk factors of IAH.

Objective To explore the clinical effect of traditional Chinese medicine (TCM) dialectical therapy for treatment of gastrointestinal dysfunction in patients with acute lung injury / acute respiratory distress syndrome(ALI/ARDS)undergoing mechanical ventilation. Methods A prospective,randomized controlled trial was conducted. Ninety-six ALI/ARDS patients admitted in intensive care unit(ICU)and treated with mechanical ventilation in Tianjin First Central Hospital were chosen and randomly divided into traditional Chinese medicine(TCM) group and conventional therapy group using a random number table,48 patients in each group. Conventional therapy alone was used in conventional therapy group,and TCM therapy of primarily using Dachengqi decoction combined with conventional therapy was applied in TCM group〔Dachengqi decoction was composed of mongolian milkvetch root 15 g, pilose asiabell toot 15 g,Chinese angelica 10 g,officinal magnolia bark 10 g,tangerine peel 10 g,immature tangerine fruit 10 g,peach seed 10 g,white peony root 12 g,red peony root 12 g,immature bitter orange 6 g,mongolian dandelion herb 30 g,radish seed(stir-fried)30 g,foxtail millet sprout 20 g,barley sprout 20 g,glauber salt 9 g (with water),rhubarb 10 g(added in water at last)〕,one dose orally taken daily for 28 days. The intra-abdominal pressure(IAP),gastrointestinal diseases in TCM symptom score and the incidence of gastrointestinal dysfunction were compared between the two groups before treatment and on the 3rd,6th and 8th day after treatment. Results There were no statistical significant differences in IAP and TCM symptom scores between the two groups before treatment (both P>0.05),but after treatment with the prolongation of therapeutic time the IAP and TCM symptom scores were decreased gradually compared with those before treatment,having reached the valley value on the 18th day and the changes in TCM group were more remarkable〔IAP(mmHg,1 mmHg=0.133 kPa):0.91±0.69 vs. 2.08±0.92, TCM symptom score:48.33±10.41 vs. 88.33±20.21,both P<0.05〕. In the TCM group,the incidences of the untoward symptoms and signs of gastrointestinal dysfunction such as bleeding of stress ulcer,toxic intestinal paralysis, abdominal distension,diarrhea and so on were lower than those in conventional therapy group〔stress ulcer bleeding:16.7%(8/48)vs. 39.6%(19/48),toxic intestinal paralysis:16.7%(8/48)vs. 43.8%(21/48),abdominal distension:10.4%(5/48)vs. 37.5%(18/48),diarrhea:6.3%(3/48)vs. 33.3%(16/48),all P<0.05〕. Conclusion Addition of TCM Dachengqi decoction on conventional treatment can effectively lower the incidence of gastrointestinal dysfunction in treatment of patients with ALI/ARDS undergoing mechanical ventilation.

Objective To compare the incidence of perioperative complications and the degree of traumatic stress reaction between thoracoscopic radical esophagectomy and open radical esophagectomy for esophageal cancer.Methods 97 patients with esophageal cancer in our hospital were divided into group A (thoracoscopic esophagectomy,n =51) and group B (open esophagectomy,n =46) according to the operation method.The group A was given thoracoscopic radical resection of esophageal cancer,while the group B was given open radical resection of esophageal cancer.The operative indexes (intraoperative blood loss,intraoperative fluid volume,operative time,incision length),the incidence rate of perioperative complications,body traumatic stress response indexes [white blood cell count (WBC),serum C-reactive protein (CRP),free thyroxine (FT4)] and tumor markers [squamous cell carcinoma antigen (SCC),carbohydrate antigen 125 (CA125)] were compared between the two groups.Results The group A had less intraoperative blood loss,intraoperative fluid volume and shorter operative time and incision length compare with group B (P ≤ 0.05).The incidence rate of perioperative complications in group A was lower than that in group B (17.65％ vs 36.96％) (P ≤ 0.05).There was no significant difference in the levels of WBC,CRP and FT4 between the two groups at the same time (P ＞ 0.05),so as the levels of SCC and CA125 (P ＞ 0.05).Conclusions Compared with open radical esophagectomy,the thoracoscopic esophagectomy had lower incidence of perioperative complications,but there was no significant difference in the degree of traumatic stress reaction between the two methods.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

Objective: To analyze the clinical characteristics of two groups(vascular classification declines or not in narrow band imaging (NBI) of patients with advanced hypopharyngeal carcinoma after induced chemotherapy, to follow-up and compare the survival differences between the two groups, and to explore the effect of vascular changes on clinical prognosis after induced chemotherapy in patients with advanced hypopharyngeal carcinoma. Methods: Clinical data of 56 patients with advanced hypopharyngeal carcinoma from August 2014 to September 2016 in Beijing Tongren Hospital, Capital Medical University were collected. The patients were divided into two groups according to NBI vascular classification declines or not after induced chemotherapy. The survival of patients and the impact of different factors on the prognosis were retrospectively analyzed. SPSS 24.0 statistical software was used for analysis. Frequency data were compared between the two groups using χ² test. Kaplan-Meier method and Cox regression analysis were employed for survival analysis and Log-Rank test was used for inter-group comparison, P<0.05 was statistically significant. Results: There was significant difference in overall survival rate(OS) between two groups of patients with advanced hypopharyngeal carcinoma after induced chemotherapy (P<0.05). Multivariate analysis showed that NBI vascular classification changes after induced chemotherapy was the impact factor for prognosis of advanced hypopharyngeal carcinoma after induced chemotherapy. Conclusion In addition to recurrence and metastasis, NBI vascular classification changes is the important impact factor for prognosis of advanced hypopharyngeal carcinoma after induced chemotherapy. Patients with NBI vascular classification declines have significant survival benefit. The patients with advanced hypopharyngeal carcinoma should be checked with NBI examination before and after induced chemotherapy. NBI should be included in the routine screening indicators for prognosis of advanced hypopharyngeal carcinoma.
