Objective To investigate the clinical features , treatment regimen , and prognosis evaluation of tertiary peritonitis (TP). Methods Seventy-eight cases with TP were randomly enrolled into 2 groups, including the simple western medicine-treated group (32 cases) and the integrated traditional Chinese and western medicine-treated group (46 cases). The prognoses were evaluated according to the acute physiology and chronic health evaluationⅢ (APACHEⅢ, APⅢ) scoring. Results The mortality rate was 71.9% (23 of 32) in patients received the simple western medicine and was 32.6%(15 of 46) in patients received the integrated traditional Chinese and western medicine with significant difference between these two groups (P < 0.01). There was a significant correlation between AP Ⅲscore and actual mortality (r=0.73,P<0.01), and predicted mortality (r=0.76, P<0.01). Conclusions The therapeutic effect is acceptable and satisfactory for the TP patients received the integrated traditional Chinese and western medicine. The AP Ⅲ scoring system can be used to predict the prognosis of TP patients.

Objective To investigate the effects of total nutrient admixture (TNA) on the recovery of patients with gastric cancer after radical gastrectomy.Methods The clinical data of 50 patients with gastric cancer who were admitted to the Affiliated Hospital of Luzhou Medical College between March 2013 and March 2014 were retrospectively analyzed.Among 50 patients receiving radical gastrectomy,26 patients receiving TNA were allocated to the experimental group and 24 patients receiving conventional fluid infusion were allocated to the control group.Patients in the experimental group received the nutritional support therapy using TNA at preoperative day 5 and at postoperative days 1-5,and patients in the control group received the postoperative intravenous rehydration including water,glucose,electrolyte,vitamins and micro elements.The nutritional indexes [albumin (Alb),prealbumin,transferrin and hemoglobin (Hb)],time to anal exsufflation,incidence of complications (wound infection,anastomotic leakage,blooding and intestinal obstruction) and duration of hospital stay were observed before nutritional support therapy and at postoperative day 8.The count data were analyzed using the chi-square test.The chi-square value of correction for continuity was used when 1 ≤ minimum theoretical frequency ≤ 5.The measurement data with normal distribution were presented as (x) ±s and analyzed using the t test or repeated measures ANOVA.The ordinal data were analyzed by the analysis of variance.Results The Alb,prealbumin,transferrin and Hb in the experimental group were (38.6 ± 2.0) g/L,(281 ± 33) mg/L,(2.5 ± 0.9) g/L and (111 ± 20) g/L before nutritional support therapy and (38.2 ± 1.9) g/L,(277 ± 16) mg/L,(2.3 ± 1.1) g/L and (112 ± 37) g/L at postoperative day 8,respectivley.The Alb,prealbumin,transferrin and Hb in the control group were (38.3 ±2.4) g/L,(287 ± 34) mg/L,(2.4 ± 1.1) g/L and (107 ± 21) g/L before nutritional support therapy and (30.3 ±2.3) g/L,(190 ± 41) mg/L,(1.6 ± 0.3) g/L and (93 ± 22) g/L at postoperative day 8,respectivley.There were significant differences in the nutritional indexes at postoperative day 8 between the 2 groups (F =174.042,95.637,9.529,4.919,P ＜ 0.05).The time to anal exsufflation in the experimental group were (52 ± 11) hours,which was significantly different from (70 ± 12) hours in the control group (t =-5.176,P ＜ 0.05).The incidence of complications was 15.4％ (4/26) in the experimental group,which was significantly different from 58.3％ (14/24) in the control group (x2=6.460,P ＜0.05).Patients with complications in the 2 groups were cured by anti-infective or symptomatic treatment.The duration of hospital stay was (9 ± 3) days in the experimental group and (12 ± 4) days in the control group,with a significant difference between the 2 groups (t =-2.912,P ＜ 0.05).Conclusion TNA can improve the nutritional status of patients after radical gastrectomy in a short time.It could help patients to get through the perioperative period smoothly,and enhance the postoperative recovery.

Objective To explore the clinical value of gastric bare area (GBA) for the prognosis of gastric fundus and cardia carcinoma.Methods The data of 82 patients with gastric fundus and cardia carcinoma from January 2010 to December 2011 were retrospectively analyzed.The patients were divided into group A (49 cases) with cancer cell invasion in GBA and group B (33 cases) without invasion in GBA.All the patients underwent D2 gastrectomy plus surgical resection of GBA and were treated by 6 cycles of postoperative FOLFOX-4 chemotherapy scheme.Postoperative follow-up and survival analysis were carried out for patients in both groups.Results According to survival analysis (Kaplan-Meier method),the postoperative 1-,2-and 3-year cumulative survival rates of the patients in group A were 91.8 ％,57.3 ％ and 29.0 ％,respectively,while those of the patients in group B were 93.9 ％,75.0 ％ and 48.2 ％,respectively.The median survival times of the patients in group A and group B were 27.0 months and 36.0 months,respectively,which was demonstrated existing statistical significance(X2 =4.972,P =0.026).Conclusions The prognosis of gastric fundus and cardia carcinoma patients with invasion in GBA by cancer cells is poor.Surgical resection of GBA may help to improve the prognosis of the patients with gastric fundus and cardia carcinoma.

Objective To investigate the clinical value of gemstone spectral imaging (GSI) associated with patient-based low dose of contrast medium protocol in carotid CTA. Methods One hundred and twenty patients who were suspected with stenotic carotid artery or carotid plaque were prospectively enrolled in the study. All of them were divide into two groups by random number table. Group A (routine group): 60 were scanned with 120 kVp after the administration of moderate-concentration CM(320 mg/ml) with 5 ml/s injection velocity, Group B (low dose group):60 were scanned with GSI which was reconstructed using 50%ASiR after the administration of the same CM with 3 ml/s injection velocity. The contrast dose [(test bolus peak time +2 s – 5 s) × injection velocity] was calculated. Images of the two groups were compared in terms of arterial attenuation, signal-noise-ratio (SNR), contrast-to-noise ratio (CNR), and subjective image quality (IQ) score. The value of CT dose index volume (CTDIvol), dose length product (DLP) and effective dose (ED) was recorded, respectively. Data were analyzed by using independent samples t test or Mann-Whitney U test. Results The mean attenuation, noise, SNR, CNR, subjective image quality score, contrast dose, CTDIvol, DLP and ED of routine group was (363 ± 56)HU, (13 ± 4)HU, 30 ± 10, 38±13, 3.0 score, (69 ± 13) ml, 13.61 mGy,527 mGy · cm and 3.11 mSv, respectively. The above variables of low-dose-group was (378 ± 69) HU, (9 ± 4)HU, 48 ± 19, 62 ± 24, 2.0 score,(49 ± 7)ml, 12.72 mGy, 478 mGy · cm and 2.82 mSv, respectively. The mean attenuation and subjective IQ score of carotid artery had no significant differences statistically between two groups (P>0.05), respectively. The noise, SNR, CNR, contrast dose, CTDIvol, DLP and ED had significant differences statistically between two groups (P<0.05), respectively. Conclusion Compared with 120 kVp protocol, the use of GSI associated with patient-based low dose of contrast medium protocol in carotid CTA could provide equivalent image quality and higher SNR and CNR of carotid artery with a smaller amount of iodine and a lower radiation dose.
