Objective To investigate the approach and safety of minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi. Methods Clinical data of 21 cases with symptomatic caliceal diverticular calculi were retrospectively reviewed. Twelve females and 9 males aged 22 to 57 years old. The average diameter of caliceal diverticulum was 3.7 cm (2.5-7.0 cm) and average diameter of calculi was 2.3 cm (0.8-3.5 cm). The patients underwent flexible ureteroscopic lithotripsy, PCNL or mPCNL, laparoscopic techniques and laparoscopy-assisted transperitoneal PCNL, respectively. Four cases underwent flexible ureteroscopic lithotripsy. PCNL (2 cases) or mPCNL(5 cases)were performed in 7 cases. Nine cases underwent laparoscopic techniques. Laparoscopyassisted transperitoneal PCNL was performed in 1 case. Results The operations were performed successfully in 21 cases. No case need to transfer to open surgery during the operation and no major complications like perforation or organic injury were noted. One case with iatrogenic arteriovenous fistula of the kidney after 1 week postoperative was cured by delayed hemorrhage 2 days later, while clinical symptoms of 2 cases with residue calculi relieved. 19 cases without residue calculi were followed up for 6 to 12 month without recurrence. Conclusions After handling indication of treatment efficiently and creating advisable therapeutic decision-making, minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi appears to be effective and safe.

OBJECTIVETo study and identify the protein markers in the urine of children with steroid-sensitive (SSNS) and steroid-resistant nephrotic syndrome(SRNS).

METHODSTotal urinary proteins were extracted from children with SSNS before and after steroid therapy, SRNS, and healthy children (n=5 in each group). Urinary proteins were separated by immobilized pH gradient based on two-dimensional gel electrophoresis (2-DE). The silver-stained 2-DE gels were scanned with digital Image Scanner and analyzed with Image Master 2-DE Elite 3.01 software. Peptide mass fingerprint (PMF) of differential protein spots was obtained with MALDI-TOF-MS. Proteins were identified by Mascot software based on NCBI protein database.

RESULTSThere were 66 spots with different expression of protein between SRNS children and SSNS children before steroid therapy, and 24 spots and 27 spots only occurred in SRNS children and SSNS children before steroid therapy, respectively. There were 75 spots with different expression of protein between SSNS children after steroid therapy and healthy controls, and 11 spots only occurred in SSNS children after steroid therapy. Eighteen protein spots with different expression (6 spots in each nephrotic group) were chose and analyzed by MALDI-TOF-MS, and 9 types of proteins were identified.

CONCLUSIONSNine types of urinary proteins with different expression (6 spots in each nephrotic group) were identified between SRNS and SSNS children, and they might be the biomarkers for SRNS or SSNS.

Objective:To explore the effects of nutrition management based on Patient-Generated Subjective Global Assessment (PG-SGA) on nutritional idicators,quality of life and other indicators in patients with pancreatic cancer undergoing chemotherapy, to provide guidance for the implementation of the intervention plan for pancreatic cancer patients undergoing chemotherapy.Methods:This was a randomized controlled study. From January 2021 to December 2022, 96 patients with pancreatic cancer who received chemotherapy in Shanghai Changzheng Hospital and Affiliated Cancer Hospital of Fudan University were selected using convenience sampling method and divided into the observation group and the control group according to the random number table, with 48 cases in each group. The control group was given routine nursing intervention, and the observation group was given PG-SGA-based nutrition management intervention. Patients in both groups continued the intervention until discharge. Nutritional indexes, quality of life, the score of cancer-related fatigue, sleep quality and mental state before and after intervention, intervention compliance and satisfaction after intervention, and complications during intervention of both groups were compared.Results:There were 48 patients in each group ultimately. In the control group, there were 28 males, 20 females, aged (63.33 ± 4.31) years old; in the observation group, there were 27 males, 21 females, aged (63.15 ± 4.25) years old. After intervention, the PG-SGA score, serum triacylglycerol level, and scores of Revised Piper ′s Fatigue Scale and Arsens Insomnia Scale, Self-rating Anxiety Scale and Self-rating Depression Scale in the observation group were (3.87 ± 1.16) points, (1.35 ± 0.52) mmol/L, (3.79 ± 0.67) points, and (5.31 ± 2.05), (44.55 ± 5.14), (45.15 ± 5.08) points respectively, lower than the control group ′s (5.77 ± 1.58) points, (2.04 ± 0.35) mmol/L, (4.82 ± 0.88) points, and (7.29 ± 2.14), (51.74 ± 5.18), (52.26 ± 5.11) points, the differences were statistically significant ( t values were 4.63-7.63, all P<0.05); the serum levels of retinol binding protein and transferrin were (18.13 ± 2.41) mg/L and (61.25 ± 5.34) ng/L, respectively, higher than the control group ′s (15.29 ± 2.33) mg/L and (48.31 ± 5.28) ng/L, with statistical significance ( t=5.87, 11.94, both P<0.05). The symptom domain score in the observation group after intervention was (56.17 ± 5.25) points, lower than (66.22 ± 5.57) points in the control group, while the cognitive, social, emotional, role, and physical scores were (76.35 ± 5.71 ), (77.55 ± 6.51 ), (75.87 ± 6.45), (77.38 ± 6.61), (75.75 ± 6.37) points, higher than (66.29 ± 5.39), (65.74 ± 6.34 ), (64.22 ± 6.18), (66.56 ± 6.26), (65.74 ± 6.11) points in the control group ( t values were 7.86 to 9.10, all P<0.05). Conclusions:Nutritional management based on PG-SGA could reduce the degree of cancer-induced fatigue, relieve negative emotions, improve the overall nutritional status, improve intervention compliance, reduce the occurrence of complications; improve sleep quality, quality of life, and patient ′s satisfaction.

OBJECTIVETo evaluate the clinical value of radial endorectal ultrasound (ERUS) in the assessment of preoperative staging of rectal carcinoma.

METHODSOne hundred and ten patients with rectal cancer underwent preoperative endorectal ultrasound (ERUS) examination in our hospital from February 2010 to September 2011. ERUS was performed using a Hitachi 900, Hitachi HI Vision Preirus US scanner, with a 5 - 10 MHz rigid rotating radial transducer and a focal length of 2 - 5 cm. The size, shape, echo pattern, infiltration depth, degree of circumferential involvement, extra-rectal invasion of the lesions and lymph node involvement were observed. The results of ERUS staging were compared with histopathological findings of the surgical specimens.

RESULTSThe accuracy of ERUS for T staging was 91.4%. The accuracy of ERUS in diagnosing stage T1, T2, T3, T4 cancers was 92.7%, 88.2%, 88.2% and 96.4%, respectively. The sensitivity of ERUS in diagnosing stage T1, T2, T3, T4 cancers was 92.3%, 72.7%, 85.4% and 71.4%, respectively. The specificity of ERUS in diagnosing stage T1, T2, T3, T4 cancer was 92.9%, 92.0%, 90.3% and 100.0%, respectively. Comparing the consistency of preoperative T-staging and postoperative pathological results, the Kappa value was 0.75, with a considerable consistency. The sensitivity, specificity, and accuracy of ERUS in the assessment of lymph node metastasis were 74.2%, 89.9% and 85.5%, respectively. Comparing the consistency of preoperative N-staging and postoperative pathological results, the Kappa value was 0.64, with a considerable consistency.

CONCLUSIONSERUS is a practical and accurate tool in assessment of preoperative staging of rectal tumors in regard to tumor invasion depth (T) and regional lymph node status (N), with advantages of simple operation, less pain, and high accuracy.

OBJECTIVETo investigate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in preoperative T-staging of gastric cancer.

METHODSA sulfur hexafluoride-filled microbubble ultrasound contrast agent and a continuous real-time imaging technique of contrast pulse sequencing were used. Normal gastric wall was examined by CEUS in 8 healthy volunteers and the results were compared with the findings on multislice computed tomography. Sixty-two patients with gastric cancer proved by biopsies who received preoperative CEUS examination were involved in this study, and the CEUS result was compared with postoperative pathological findings.

RESULTSThe normal gastric wall presented a one-layer structure in the portal venous phase and a three-layer structure in the arterial and equilibrium phase including a slightly hyper-enhanced inner layer, a hypo-enhanced intermediate layer, and a markedly hyper-enhanced outer layer, which corresponded histologically to the mucosal, submucosal, and muscular-serosal layer, respectively. The accuracy of transabdominal ultrasonography and CEUS in determining the T stage of gastric cancer was 72.9% and 88.1% respectively, and the difference was statistically significant (chi(2)=4.37, P=0.036).

CONCLUSIONSCEUS shows the normal gastric wall as a one- or a three-layer structure, which provides a theory base for CEUS in preoperative T-staging of gastric cancer. CEUS is a useful diagnostic method for preoperative T-staging of gastric cancer.

Objective To investigate the association between nudix hydrolase 1 (NUDT1) polymorphism and the purine-induced leukopenia.Methods A total of 176 patients with Crohn's disease were enrolled.NUDT1 rs3735092 and rs34996498 were detected using Sequenom (R) Massarray matrix-assisted laser desorption/ionization-time of flight platform.The association between different genotypes and the purine-induced leukopenia was been analysed.Results NUDT1 rs34996498 (A ＞ G) was significantly associated with the purine-induced leukopenia (P ＜0.05),and this mutation showed marginal effect after Bonferroni correction.The mutation of NUDT1 rs3735092 (C ＞ T) was not associated with the purine-induced leukopenia (P ＞ 0.05).We found female had significant higher risk of the purine-induced leukopenia than male (P ＜0.01).Conclusion NUDT1 rs34996498 polymorphism might influence the purine-induced leukopenia and further study with larger sample size was warranted.

Objective To investigate the association between polymorphisms in ADCY3,C10orf55,IL18RAP,CARD9,NFIL3 and susceptibility for Crohn's disease in Chinese population. Methods A total of 192 patients with Crohn's disease and 192 healthy controls were enrolled. Polymorphisms of those genes was detected by Sequenom iPLEXTM Mass Assay platform. The relationship between gene polymorphisms and Crohn's disease susceptibility was analyzed. Results A polymorphism within ADCY3, rs6545800,was susceptibility loci for Crohn's disease. Compared with the TT genotype,CC + CT carriers were less likely to develop Crohn's disease (P = 0. 004,OR = 0. 45,95％ CI: 0. 26-0. 78) . There was a weak correlation between rs4743820 within the NFIL3 gene and the susceptibility to Crohn's disease. Compared with TT carriers,CC + CT carriers had a lower probability of experience Crohn's disease (P = 0. 056, OR = 0. 64, 95％ CI:0. 40-1. 02). In addition,we also found that CC + CT of rs4743820 carriers had a lower incidence of upper gastrointestinal lesions than TT carriers (P = 0. 017,OR = 0. 26,95％ CI: 0. 08-0. 83). Conclusion The polymorphisms in ADCY3 and NFIL3 gene are associated with susceptibility to Crohn's disease in Chinese population.

OBJECTIVETo evaluate the efficacy and safety of capecitabine as first-line therapy in patients with advanced and recurrent colorectal cancer.
