The therapeutic efficacy in the treatment group was better than the control group.Conclusion: The clinical therapeutic efficacy treated with lumber vertebral traction plus Ding's Rolling Technique was better than simple lumber vertebral traction in treating prolapse of lumbar intervertebral disc.

Objective To study the characteristics and diagnosis of renal sinus lipomatosis (RSL) complicated with renal staghorn calculi, and report our preliminary experience on percutaneous nephrolithotripsy for the disease. Methods A total of 547 patients with complex renal calculi were admitted to our hospital from January 2005 to June 2007. In 2 of them, RSL complicated with renal staghorn calculi was diagnosed by B-ultrasonography, CT, and MRI. Both the patients were female, aged 42 and 82 years respectively. B-ultrasonography-guided percutaneous nephrolithotripsy was performed on the two patients without removing the kidneys.Results Totally, 7 ml and 5 ml of stones were removed respectively from the two patients by percutaneous nephrolithotripsy. No retained calculi were found by KUB performed one week postoperation. Biopsy of the submucosal fat obtained from the renal pelvis during the operation showed hyperplasia and fibrosis of fatty tissues and inflammatory effusion. The patients were followed up for half a year, during which no recurrence of renal calculi occurred, and no abnormal fatty tissues were found at the renal sinus or surrounding the kidney. Conclusions Imaging examination is valuable for the diagnosis of RSL. B-ultrasonography-guided percutaneous nephrolithotripsy is safe and effective for RSL complicated with renal calculi.

Objective To investigate the expression and distribution of aquaporin 3 (AQP3) in mouse early embryos at different stages.Methods Controlled ovarian hyperstimulation model of Kunming mouse was used to collect four-cell embryos,eight-cell embryos,morula stage,and early blastocysts.Immunofluorescence microscopy and laser confocal microscopy were used to detect expression and distribution of AQP3 channels in these stages.Results Fluorescence signal of AQP3 was found in four embryonic stages of mice.Distribution within embryo was different at different embryonic stages.AQP3 was mainly expressed on the karyotheca of blastomeres at four-cell and eight-cell stage.In morula stage,AQP3 was mainly expressed on cell membrane of each blastomere.In early blastocysts,AQP3 was predominantly expressed on the cell membrane and cytoplasm of trophoblastic cell.Conclusions AQP3 trans-membrane channel might have potential regulation function on mouse embryonic development.

Objective:To compare the efficacy and safety of tubeless percutaneous nephrolithotomy ( tubeless-PCNL) and ureteroscopic lithotripsy ( URL) in treatment of impacted upper-ureteral calculi ≥1.5 cm in size.Methods:Patients with ureteral stones sized ≥1.5 cm and lodged above the fourth lum-bar vertebra who were treated between September 2009 and July 2013 in Peking University People ’ s Hos-pital were retrospectively analyzed .In the study , 182 patients underwent tubeless-PCNL or URL treat-ment respectively , and the operation success rates were compared .The duration of operation , intraopera-tive blood loss ( average hemoglobin decrease ) , complications , mean hospital stay and residual stone rates were also compared.Results: Fifty-four patients underwent tubeless-PCNL treatment,the average stone size was (1.9 ±0.4) cm,nephrostomy tubes were placed in two patients ,and the operation success rate was 96.3%(52/54).In the rest of the 52 patients,and the mean operation time was (30.1 ±14.8) minutes with an average postoperative hemoglobin decrease of (10.2 ±6.1) g/L, and the mean hospital stay was (3.0 ±1.4) days.Only one of the patients had residual fragments (2%).The main complica-tions included minor perirenal hematoma in 1 patient, fever in 2 patients, elevated blood WBC in 11 patients,and analgesics requirement in 3 patients.In the study, 128 patients were treated with URL,the average stone size was (1.7 ±0.3) cm.19 procedures failed,and 10 patients were converted to PCNL, extracorporeal shock wave lithotripsy was executed subsequently after double -J stent placement in 5 patients,and migration of calculi or stone fragments happened in 4 patients.The mean operative time was (51.3 ±25.5) minutes for the remaining 109 patients with a hemoglobin reduction of (5.2 ±7.2) g/L. The mean hospital stay was (2.9 ±1.3) days, and residual stones were found in 13 of the 109 patients (11.9%).The main complications included fever in 3 patients, elevated blood WBC in 42 patients, an-algesics requirement in 13 patients because of pain in the urethra or flank .The size of the stones between the two group didn ’ t show significant difference ,but the success rate of the tubeless-PCNL procedure was significantly higher .Except that hemoglobin decrease was slightly higher in the tubeless-PCNL group ,the mean operative time , the rate of residual stones and rate of complications of the tubeless-PCNL group were lower significantly.Conclusion:Treating stones above 4th lumbar vertebra larger than 1.5 cm were challenging .It is difficult to treat these stones with URL because of a high probability to fail , but on the contrary, tubeless-PCNL was more likely to be performed successfully .For surgeons experienced with the PCNL technology, treating stones≥1.5 cm with tubeless-PCNL procedure may turn out to be more effi-cient and with a higher operation success rate , and the risk of complications was lower without lengthe-ning the postoperative hospital stay .

Objective To summary our experiences in percutaneous nephrolithotomy for treating the caliceal diverticular calculi and postoperative outcome with technical modification.Methods A retrospective review was performed on 34 patients with caliceal diverticular calculi who underwent percutaneous nephrolithotomy between January 2009 and June 2013.The patients were divided into 2 groups.In group A (1 1patients),stones were removed and diverticular neck was incised.In group B (23 patients),fulguration of diverticular wall was performed after the stone removal and diverticular neck incision.Group A had 11 cases including 4 male and 7 female with average age (36.7± 16.0) years.Mean size of stone was (1.8±0.4) cm.Mean maximum diameter of diverticulum was (2.3±0.5) cm.Group B had 23 cases including 10 male and 13 female with average age (40.1±12.0) years.Mean size of stone was (1.9±0.6) cm.Mean maximum diameter of diverticulum was (2.3±0.8) cm.There were no significant difference in stone size and maximum diameter of diverticulum within two groups (P＞0.05).The following parameters such as operative time,drop in hemoglobin,stone clearance,complication rate and ablation rate of diverticulum were compared between two groups.Results In group A,average operative time was (62.7±11.7) min.Mean hemoglobin dropping was (12.0t9.7) g/L.Stone clearance rate was 90.9％ (10/11) and overall complications rate was 18.2％ (2/11).The ablation rate of diverticulum was 63.6％ (7/11).In group B,average operative time was (76.3±21.6) min.Mean Hemoglobin reducing was (12.9±16.7) g/L.Stone clearance rate was 91.3％(21/23) and overall complication rate was 21.7％.The ablation rate of diverticulum was 91.3％ (21/23).There was no significant difference in stone clearance and complication rate between two groups.It seemed that the operativc timc in group B was longer than that in group A.However,no significant difference was found (P＞0.05).The ablation rate of diverticulum in group B was significantly higher than that in group A (P＜0.05).Conclusion In percutaneous nephrolithotomy treatment for caliceal diverticular calculi,fulguration to diverticular wall is an effective method to achieve diverticular obliteration and reduce possibility of stone recurrence.

Objective Maple syrup urine disease (MSUD) is a rare metabolic disorder caused by deficiency of the activity of branched-chain 2-keto acid dehydrogenase complex.The complex contains E1α,E1β and E2 subunits which are encoded by BCKDHA,BCKDHB or DBT genes respectively.Mutation in any gene will cause MSUD.The aim of this study was to analyze the gene mutations of four cases with MSUD and carry out prenatal diagnosis for these four families for MSUD.Methods From 2005 to 2010,four neonates (two males and two females) were diagnosed as MSUD at 2,5,10and 26 days of life.The coding regions of BCKDHA gene and BCKDHB gene in the above four cases were amplified by polymerase chain reaction and analyzed by direct DNA sequencing.During the second pregnancy of the same mother,the amniotic fluid was drawn out at 16-20 weeks for gene mutation analysis after the amniocytes were cultured.Results Mutation analysis revealed six mutations in four patients,including four novel mutations (c.308T＞C,c.562G＞T,c.1279C＞G and c.1280-1291de112) and two previously reported mutations.Five mutations (c.308T＞C,c.562G ＞T,c.868G＞A,c.1279C＞G and c.1280-1291de112) were detected on BCKDHA gene in three patients.While one mutation (c.853C＞T) was found on BCKDHB gene in one patient.Only one mutation was found in the amniocytes of each patient's mother at their second pregnancies suggesting a MSUD heterozygous fetus.Conclusions Analysis of BCKDHA and BCKDHB allowed preliminary understand of gene mutations in the four MSUD families,and made prenatal diagnosis possible,which helped in consultation in the second pregnancy.

OBJECTIVETo assess the feasibility and safety of thoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation.

METHODSSixty patients with pulmonary bulla were randomized into two groups (n=30) to undergo video-assisted thoracoscopic surgery (VATS) for bulla resection with laryngeal mask anesthesia and high-frequency low tidal volume lung ventilation general anesthesia and or with intubation anesthesia and one-lung ventilation through double-lumen endotracheal intubation.

RESULTSNo significant differences were found in anesthesia time, surgery time, intraoperative lowest SpO2, intraoperative highest PetCO2, operative field, anesthetic effects, or blood loss between the two groups. The post-operative WBC and NEU% showed significantly smaller increments in the mask anesthesia group than in the intubation group, and the postoperative awake time, initial eating time, ambulation time, in-hospital stay, and drainage time were significantly shortened in the former group with also lower incidences of gastrointestinal reactions, throat discomfort and hoarseness.

CONCLUSIONThoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation is safe and feasible and results in better patient satisfaction and shorter in-hospital stay than procedures performed under intubation anesthesia with one-lung ventilation.
