Thirty patients with malignant obstructive jaundice were treated with biliary stent implantation+brachytherapy+conformal radiotherapy (study group; n=15) or biliary stent implantation alone (control group; n=15). Total bilirubin (TBIL) levels significantly declined within 1 month in both groups. However, at 6 months, TBIL values began to increase in the control group and continuously declined in the study group. Maximum tumor diameter increased in the control group, while decreased in the study group (remission rate, 13/15 ). As for the study group, the survival rate at 0. 5, 1, and 2 years was 15/15,14/15, and 10/15, respectively, higher than the control group (15/15,5/15,and 1/15) . Combining biliary stent implantation with brachytherapy and conformal radiotherapy might be a safe and effective treatment of choice for patients with malignant obstructive jaundice.

Objective To study the application value of radiotherapy optimization after modified radical mastectomy.Methods From January 2012 to January 2015,one hundred and twelve patients treated with modified radical mastectomy in Taizhou Cancer Hospital were enrolled and divided randomly into group A,B and C.40 patients in group A received modulated radiation therapy(MRT) with 2.0Gy/f,25 times,DT50Gy for 33-35d;35 cases in group B received concurrent chemoradiotherapy with MRT and 37 cases in group C received concurrent chemoradiotherapy with large segmentation scheme of 2.66Gy/f,16 times,DT42.56Gy for 22-24d.The recurrence rate,survival rate and the incidence of acute and chronic radiation injury of the 3 groups were compared.The parameters of V5,V10,V20 and V30 of ipsilateral lung was recorded by dose volume histogram(DVH).Results The total recurrence rate in group C was significantly lower than that of the other two groups (16.2％(6/37) vs.28.6％(10/35) vs.42.5％(17/40),x2 =6.409,P=0.041),while the total survival rate was significantly higher than that of the other two groups (89.2％ (33/37) vs.77.1％ (27/35) vs.65.0％ (26/40),x2 =6.313,P =0.043),and there was no significant difference in the local recurrence and distant metastasis rate in the 3 groups (P＞0.05).The incidence of total radiation injury in group C was lower than that of the other two groups (21.6％ (8/37) vs.42.9％ (15/35) vs.50％ (20/40),x2 =6.973,P =0.031),and there was no significant difference in the incidence of acute and chronic injury and the grade of injury in the 3 groups (P＞0.05).The values of VS,V10,V20 and V30 increased gradually in the 3 groups.The V5 and V10 in group C were significantly higher than those of the other two groups ((32.9 ± 7.4) ％ vs.(17.5 ± 5.9) ％ vs.(16.8 ± 6.4) ％,F =18.625,P=0.000,(42.4±7.3)％ vs.(39.3±5.8)％ vs.(35.5±6.0)％,F=15.624,P=0.000),and there was no significant difference in V20 and V30 among the three groups (P＞ 0.05).Conclusion The combination of concurrent chemoradiotherapy and breast cancer after modified radical mastectomy is of great value in improving prognosis and reducing radiation damage.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.
