To investigate some rare causes of obstructive jaundice in children. Three school children with obstructive jaundice caused by uncommon causes were analyzed. Despite pre operative physical examination, B Ultrasonic and CT examinations, the diagnosis was not established. The main clinical manifestation of three patients was obstructive jaundice. Postoperative pathological examination proved that one patient was suffering from cryptococcus neoformans infection of the common bile duct, another embryonal rabdomyosarcoma of common bile duct, and the third primary hydatid cysts in the common bile duct. They were all treated with surgical removal of the lesions, followed by reconstruction of the bile duct and other adjunctive treatment with satisfactory result. The results suggest that obstructive jaundice in children may be caused by some unusual diseases. Comprehensive analysis and corresponding treatments were recommended.

Objective:To compare 5-year overall survival (OS) and disease free survival (DFS) between preoperative three dimensional conformal radiotherapy (3DCRT) and volumetric medulated arc therapy (VMAT) concurrently combined with chemotherapy for locally advanced rectum cancer (LARC), and analyze the value of induction and/or consolidation chemotherapy in these circumstances.Methods:334 patients with LARC treated with preoperative 3DCRT (172 cases) and VMAT (162 cases) concurrently combined with chemotherapy, main protocol XELOX (capecitabine plus oxaplatin), and subsequent surgery in Sun Yat-sen University from May 2007 to April 2013 were retrospectively analyzed. The radiation prescription dose for VMAT group was 50 Gy 25 fractions for planning target volume1(PTV 1), and 46 Gy 25 fractions for PTV 2. The radiation prescription dose for 3DCRT group was 46 Gy 23 fractions for PTV 2. One hundred and eighty-five cases of all received preoperative concurrent chemoradiotherapy (namely, CCRT group), 149 cases received preoperative concurrent chemoradiotherapy plus median 2 courses (1-7 courses) induction and/or consolidation chemotherapy (namely, CCRT±induction chemotherapy±consolidation chemotherapy group), whose main chemotherapy protocol was XELOX. Difference of 5-year OS and DFS between 3DCRT and VMAT group was compared. The rate differences of acute toxicity during chemoradiotherapy, postoperative complications, ypCR, and survival between CCRT group and CCRT±induction chemotherapy±consolidation chemotherapy group were analyzed. Results:After a median follow-up of 62.3 months (2.4-119months) for the 334 patients, no any significant difference for 5-year OS (79.0% vs. 83.2%, P=0.442) and 5-year DFS (77.0% vs. 82.1%, P=0.231) between 3DCRT and VMAT group was observed. There was no any significant difference for the Grade 3 hematological toxicity (7.0% vs. 12.1%, P=0.114) and non-hematological toxicity (14.1% vs. 16.8%, P=0.491) during chemoradiotherapy, postoperative complications (17.3% vs. 17.4%, P=0.971), ypCR rate (25.4% vs. 30.2%, P=0.329), 5-year OS (80.5% vs. 82.0%, P=0.714) and 5-year DFS (78.8% vs. 81%, P=0.479) between CCRT group and CCRT±induction chemotherapy±consolidation chemotherapy group. Conclusions:Compared with 3DCRT, the physics advantage of VMAT technique does not significantly convert into clinical benefits and improve 5-year OS and DFS, even further boosting radiation dose to the gross tumor volume. It is safe for median 2 courses of induction and/or consolidation chemotherapy before and or after preoperative concurrent chemoradiotherapy in the treatment of LARC, though it does not significantly improve ypCR rate and survival.

Objective To evaluate the efficacy of chemoradiotherapy alone and prognostic factors for locally advanced rectal cancer. Methods The clinical data of 47 patients with locally advanced rectal cancer who were admitted to our hospital and mostly treated with chemoradiotherapy alone from 2003 to 2010 were retrospectively analyzed. Three of the patients received radiotherapy alone. The Kaplan?Meier method was used to estimate overall survival (OS), progression?free survival (PFS), and distant metastasis?free survival ( DMFS ) rates, and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox regression model was used for multivariate prognostic analysis. Results In all patients, the 3?and 5?year OS rates were 53?2% and 33?2%, respectively, while the 3?and 5?year PFS rates were 37% and 31%, respectively. During the follow?up, 15 patients (32%) had local progression with PFS of 1?60 months (median PFS, 14 months);23 patients (49%) had distant metastasis with DMFS of 2?60 months ( median DMFS, 17 months) . Patients treated with high?dose radiotherapy had significantly lower 3?and 5?year local progression rates than patients treated with medium?dose radiotherapy ( 11% vs. 54%;11%vs. 57%;P=0?004). After chemoradiotherapy, 9 patients (19%) had clinical complete response (cCR), and the 3?and 5?year OS and PFS rates in those patients were all 8/9. The univariate analysis indicated that tumor distance from the anus and cCR were influencing factors for prognosis ( P= 0?026;P= 0?000 ) . However, the multivariate analysis showed that cCR was the only influencing factor for survival ( HR=12?24;95% CI, 1?64 ?91?29;P= 0?015 ) . Conclusions Chemoradiotherpay or radiotherapy alone is effective and safe in the treatment of patients with locally advanced rectal cancer who have to give up surgery or have unresectable tumors. High?dose radiotherapy may improve local control rate. Complete response to chemoradiotherapy predicts satisfactory treatment outcomes.

Objective:To investigate the value of the ratio of heparin binding protein (HBP) to albumin (ALB) in diagnosis and predict the severity of Kawasaki disease shock syndrome (KDSS).Methods:This study was a retrospective study. Pediatric patients with Kawasaki disease (KD) admitted to the Children's Intensive Care Unit and department of Pediatric Emergency Center of Hunan Children's Hospital from January 2019 to May 2022 were enrolled. The HBP/ALB ratio was calculated according to HBP and serum ALB. The children were divided into three groups (low, medium, and high ratio groups) according to the median and upper and lower quartiles of the HBP/ALB ratio. The differences of each index among the three groups were compared. The receiver operating characteristic curves were drawn to evaluate the clinical value of the HBP/ALB ratio in diagnosis of KDSS and the severity of the disease.Results:A total of 111 cases were included in this study, including 28 cases in the low ratio group, 56 cases in the medium ratio group, and 27 cases in the high ratio group. There were 24 cases with coronary artery damage, 87 cases without coronary artery damage, 27 cases with abnormal ECG findings, and 17 children with KDSS (including 5 cases in the medium ratio group, and 12 cases in the high ratio group). The incidence of KDSS, coronary involvement, and abnormal electrocardiogram proportions in the high ratio group were significantly higher than those in the other two groups. Compared with low and medium ratio groups, the levels of cardiac troponin I, N-terminal pro-brain natriuretic peptide, lactate, stroke output variation, trends in thoracic fluid content, white blood cell count, C-reactive protein, procalcitonin, and D-dimer levels were higher in the high ratio group, while ALB and blood sodium levels were lower in the high ratio group (all P<0.05). There was no significant difference in above indicators between the low and medium ratio groups (all P>0.05). The HBP/ALB ratio had a higher area under the curve, sensitivity, and specificity (0.942, 0.882, and 0.883, respectively) in predicting KDSS compared to HBP alone (0.776, 0.842, and 0.670, respectively). Conclusion:The HBP/ALB ratio could reflect the severity of children with KD and has certain clinical value for prognostic evaluation.
