Objective To investigate the safety and efficiency of laparoscopic gallbladder - preserving chole-lithotomy in the treatment of cholecystolithiasis in children. Methods The clinical data obtained from 18 children with gallstones undergoing laparoscopic gallbladder - preserving cholelithotomy at Dalian Children′s Hospital of Dalian Medi-cal University during July 2010 and December 2016 were retrospectively analyzed. Eight boys and 10 girls of 5 - 14 years old [mean (9. 2 ± 3. 1)years old]were included in the study,of whom 11 cases had a single stone,7 cases with multiple stones. All patients were followed up for 3 - 72 months. Results All of 18 patients without pancreaticobiliary maljunction were diagnosed by Color Doppler ultrasound and magnetic resonance cholangiopancreatography(MRCP). Gallbladder functions were assessed preoperatively and they were all in good condition. Laparoscopic gallbladder - pre-serving cholelithotomy was successfully performed in all patients without conversion to cholecystectomy. Operation time was 28 - 66 min,with mean value of (40. 2 ± 14. 3)min;intraoperative blood loss was 4 - 12 mL,with mean value of (8. 3 ± 2. 8)mL;postoperative hospital stay lasted 3 - 5 d,with mean value of (3. 8 ± 1. 2)d. There were no complica-tions such as bile leakage,postoperative bleeding,biliary duct damage,biliary pancreatitis during therapy. The patients were followed up for 3 - 72 months,and the Color Doppler ultrasound showed no gallstone recurrence after surgery. Conclusions For children with good gallbladder function,laparoscopic gallbladder - preserving cholelithotomy can preserve gallbladder function and the integrity of biliary tract. The operation is easy and reliable,with minimal invasion, quick recovery,and low recurrence rate. It is a feasible method for the treatment of gallstones in children.

A sandwiched electrochemical immunoassay based on the AuNPs@GSH-CdTe as a signal label, which formed by GSH-CdTe QDs and AuNPs, with dual signal amplified by reduced graphene oxide and AuNPs was proposed for the sensitive detection of prostate specific antigen(PSA). Through a sandwich immunoreaction, the target PSA and AuNPs@GSH-CdTe labeled Ab1 were captured to rGO/AuNPs-Ab2 surface. After the HNO3-dissolution step, square wave stripping voltammetry(SWSV)analysis of the captured CdTe QDs was used to quantify the concentration of PSA. In this system, AuNPs possessedlarge specific surface and good biocompatibility, which could effectively expand the amount of antigen and GSH-CdTe QDs loading and signals amplifying, while rGO played a synergistic amplification role due to its large specific surface. The proposed method showed good linearity ranging from 0. 5 to 200 ng/mL with the detection limits of 5. 0 pg/mL. It also showed excellent selectivity, good reproducibility, satisfactory stability. In addition, the method was successfully applied to the determination of real samples. The result was satisfactory and the recovery could fall in 98. 20%- 106. 2%, which represented a novel approach for versatile detection of tumor markers.

Exclusion criteria: lower urinary tract obstruction not caused by BPH, post-void residual urine volume(PVR) >250 ml; history of acute urinary retention in the last 3 months; prostate nodules and suspected prostate cancer were revealed by digital rectal examination and transrectal B-ultrasoundor; prostate-specific antigen (PSA)≥10 ng/ml; neurogenic bladder, perivous history of bladder, prostate, or urethra operations; suffering from serious heart, lung, liver, kidney and other diseases. The patients in the experimental group were orally treated with black tomato concentrated sauce(30 g/once, 3 times/day). The patients in the placebo group were orally administrated with placebo. In the positive control group, the patients with PV≤30ml were orally treated with tamsulosin(0.2mg/once, 1 time/day), the patients with PV>30ml were orally administrated with tamsulosin and finasteride(5 mg/once, 1 time/day). All enrolled patients were treated for 3 months. At the end of third month, the IPSS, QOL, PV, PVR, Q max, average urinary flow rate(Q ave), total PSA(tPSA), free PSA (fPSA), testosterone(TST) and the incidence of adverse reaction were assessed. Results:128 of 150 cases, including 52 cases in experimental group, 36 cases in placebo group and 40 cases in positive control group, completed the study, the rest was excluded due to not take medication regularly and fail to follow-up. There were no significant differences in baseline parameters among experimental group, placebo group and positive control group ( P>0.05) in age[(63.21±8.61) vs.(62.36±6.32) vs. (63.94±7.78)years old], body mass index[(23.74±3.17) vs. (23.94±3.09) vs. (24.26±2.91)kg/m 2], IPSS[(17.5±6.6) vs. (15.4±5.8) vs. (17.9±6.8)], QOL[4.0(3.0, 4.0) vs. 4.0(3.0, 4.5) vs. 4.0(3.0, 5.0)], Q max [(8.60±3.04) vs. (9.13±2.92) vs. (9.58±3.26) ml/s], Q ave[(4.39±1.69) vs. (4.66±1.76) vs. (4.88±1.60)ml/s], PV [32.00(25.55, 45.40)vs. 30.00(24.45, 38.35)vs. 34.80(27.65, 56.65)ml], PVR[23.50(8.25, 45.75) vs.5.50(0, 47.75) vs. 29.00(0, 84.00)ml], tPSA [1.53(0.89, 3.00) vs. 1.23(0.69, 1.98) vs. 2.23(0.90, 4.15)ng/ml], fPSA [0.37(0.28, 0.76) vs. 0.37(0.22, 0.52) vs. 0.54(0.30, 0.97) ng/ml] and TST[(443.64±156.32) vs. (493.97±176.16) vs. (450.89±135.08)ng/dl]. After 3 months of treatment, the IPSS in experimental group was(9.9±5.7), QOL score 2.0(2.0, 3.0), Q max(11.78±5.24)ml/s, Q ave(5.86±3.00)ml/s, tPSA 1.64(0.96, 3.32)ng/ml and TST (475.91±177.33)ng/dl, which were significantly different compared with pre-treatment( P<0.05). In positive control group, IPSS was (9.0±6.2), QOL 2.0(2.0, 3.0), Q max(11.73±4.50)ml/s, Q ave(6.11±2.53)ml/s, tPSA 1.57(0.80, 3.09)ng/ml, fPSA 0.37(0.24, 0.63)ng/ml and TST (526.11±126.88)ng/dl, which were statistically different compared with pre-treatment( P<0.01). However, there were no significant differences in all the above indexes in placebo control group compared with the baseline( P>0.05). The numerical changes of IPSS, QOL, Q maxand Q ave between experimental group and placebo group had statistically significant differences ( P<0.05). The changes of IPSS, QOL, Q max, Q ave, PV, tPSA, fPSA and TST between positive control group and placebo group had significant differences ( P<0.05). The changes of PV, tPSA and fPSA between positive control group and experimental group had statistically significant differences ( P<0.05). The incidence of adverse reactions was 5.77% (3/52, including 1 headache and 2 stomach discomfort) in experimental group, 5.56% (2/36, including 1 headache and 1 stomach discomfort) in placebo group, and 10.00%(4/40, including 1 dizzy, 1 nasal obstruction and 2 erectile dysfunction) in positive control group. And there was no statistical difference in the incidence of adverse reactions among three groups ( P>0.05). Conclusions:Black tomato concentrated sauce shows an excellent effect on patients with LUTS/BPH, and improves the quality of life with few adverse events.
