Objective To evaluate the advantages and disadvantages of different puncture positions in percutaneous nephrolithotomy. Methods Three hundred fifty-six patients who underwent PCNL were analyzed from March 2012 to October 2015. The passage caliber was 16F-20F. There were 217 cases in prone position and 139 cases in supine position. Results The successful operation in PCNL was 354 cases , while the remaining 2 cases were performed by open surgery. The primary stone clearance rate was 75.5%. The additional PCNLs were performed in 23 cases, and 63 cases of residual calculi were treated by ESWL. 11 patients were treated due to infection or bleeding by the additional PCNLs. There were 3 cases with massive hemorrhage which were treated by Interventional embolization therapy , 12 cases in postoperative fever , no renal resection , no intestinal injury, no deaths. There was no significant difference in stone clearance rate and complication rate between the two groups. Conclusion The puncture position of PCNL can be optional based on the stone size , stone location, degree of hydronephrosis ,and patient′s cardiopulmonary condition individually.

Objective To evaluate the factors influencing the reproducibility and validity of food group intakes measured by a food frequency questionnaire (FFQ) for Chinese men. Methods A total of 214 adult men were randomly selected from the Shanghai Men Health Study (SMHS), an ongoing cohort study conducted in urban Shanghai. Each subject who had completed the first FFQ survey at recruitment took 24-hour dietary recall (24-HDR) surveys which were conducted once a month for 12 consecutive months and a second FFQ at the end of the study. Two FFQs were administered approximately 1.2 years apart. The food items listed in FFQ and obtained from 24-HDR were categorized into 11 food groups. The factors influencing the reproducibility of the FFQ was assessed by comparing the Pearson correlation of intake levels from the two FFQs, while the factors influencing the validity was evaluated by comparing intake levels from the second FFQ with the multiple 24-HDRs. Results A total of 195 men completed all 12 times of 24-HDR and twice FFQ surveys. The median Pearson correlation coefficients of the food groups between the two FFQs in older vs younger age group were 0.62 vs 0.50;in higher vs lower education level group were 0.58 vs 0.50;in higher vs lower income group were 0.51 vs 0.50;in higher vs lower BMI group were 0.50 vs 0.49. The median Pearson correlation coefficients of the food groups between the second FFQ and 24-HDRs in older vs younger age group were 0.61 vs 0.45;in higher vs lower education level group were 0.49 vs 0.47;in higher vs lower income group were 0.43 vs 0.57;in higher vs lower BMI group were 0.48 vs 0.51. Conclusions Age is the main factor influencing the reproducibility of the food group intakes by a FFQ used in the SMHS, while the factors influencing the validity are age and family income.

Objective To study the image examination of renal injuries and discuss renal explorative indications so as to spare the kidney or nephron as much as possible and improve curative rate of diagnosis and treatment. Methods An analysis was done on 286 cases that included 231 cases with close injury, 54 with open injuries, one with iatrogenic injury and 91 with combined injuries. Of all, 212 cases were examined by B-ultrasonography, 163 by CT and 132 by intravenous urography(IVU) and 6 by digital subtraction angiography(DSA); 202 cases were treated with conservative treatment and 84 with operation. Results The diagnostic positive rates of IVU, B-ultrasonography and CT were 67.4%, 72.2% and 87.7%, respectively. Among the operation cases, 42 cases were treated by renal repair, 12 by partial nephrectomy and 30 by nephrectomy. The operation rate was 29.4% and the nephrectomy rate 35.5%. Interventional treatment of the kidney was carried out in three cases. Conclusions For renal injury cases, the first and most important step is to evaluate the injury condition so as to correctly determine whether an operation exploration is needed. The injury conditions and severity are mainly determined by the image examinations that change according to injury cause, injury type and clinical symptoms. Renal exploration or not, and the operation time exert great influence on renal reservation rate and complication rate.

A thiosulfate-oxidizing bacterium TX was isolated from polysulfide wastewater treatment system.It was preliminarily identified as Halothiobacillus sp.according to its morphological,physiological proper-ties and similarity analysis of 16S rRNA gene sequence(GenBank accession No.EU871645).This bacte-rium was an obligate chemolithoautotrophic sulfur-oxidizing bacterium since it could utilize thiosulfate,elemental sulfur,tetrathionate,sulfide or sulfite as sole energy source but did not show growth on the me-dium with glucose,sucrose,fructose,lactose,mannose or yeast extract as sole carbon source.The optimal growth condition for thiosulfate oxidation was 30?C~35?C and pH 3.0~5.0 respectively.Significant reduc-tion in medium pH from 4.0 to 1.2 was observed due to oxidation of thiosulfate to sulfate during the batch culture incubation period.During the course of thiosulfate oxidation accumulation of tetrathionate was ob-served either in synthetic medium or in the mixed liquor from aeration tank of the polysulfide wastewater treatment system.This indicates that the "S4 intermediate(S4I)" pathway was responsible for thiosulfate oxidation in this bacterium.

Objective To observe the influences of stemona alkaloids on esterase isozymes activities and glycogen content of Oncomelania hupensis in order to explore the molluscicidal mechanism of stemona alkaloids.Methods O.hupensis snails were immersed in the liquid of stemona alkaloids at the concentration of 6.5 mg/L(72 h LC50),the surviving ones were picked out and sampled after being immersed for 12,24,48,72,96 h,then PAGE and anthrone colorimetry methods were used to observe the changes of liver esterase isozymes activities and tissue glycogen content of O.hupensis during the immersion period.A group of snails immersed in de-chlorinous water served as control.Results Esterase isozymes activities firstly increased,and then decreased until almost lost completely during the 96 h immersion period.Meanwhile,glycogen content gradually decreased as the immersion time extended.After being immersed for 96 h,glycogen content decreased by 72.00% compared with the control group.Conclusion Stemona alkaloids could inhibit the viability of O.hupensis by causing decrease of esterase isozymes activities and glycogen content.

Objective To investigate the state of Th1/Th2 cytokine imbalance in patients with lupus nephritis (LN) and its role in the pathogenesis. Methods Plasma level of interleukin-18 and interleukin-13 in 18 patients with active LN and 16 normal controls were measured by enzyme-linked immunoadsordent assay (ELISA). IL-18 and IL-13 expression in the renal tissues from 18 patients and 6 normal renal tissues were also detected by immunohistochemical assay. The ratio of plasma and renal IL-18/IL-13 was then calculated. Results Plasma levels and renal expression of IL-13 and IL-18 in patients with LN were increased significantly compared to those of normal controls (P0.05). The ratio of renal IL-18/IL-13 was not significantly different among all types of LN and normal controls. The ratio of plasma IL-18/IL-13 was positively correlated with LN renal tissue activity index (AI), but no correlationship could be found in renal IL-18/IL-13 ratio. Conclusion It seems that the immune disturbance in systemic lupus erythematosus (SLE) can not be simply divided into Th1 predominant and Th2 predominant. It seems far complicated than this Th1/Th2 paradigm. It may be affected by the state of disease activity, the lesion location and the type of pathology.
