Abstract
Objective: To evaluate the effects of percutaneous nephrolithotomy (PNL) in the treatment of medullary sponge kidney with calculi. Methods: A total of 77 patients (91 renal units) of medullary sponge kidney with calculi (MSK group) and 77 patients (77 renal units) with common kidney stone (control group) received PNL at Department of Urology in Peking University People's Hospital from September 2006 to February 2016 were analyzed retrospectively. The MSK group included 33 males and 44 females with a mean age of (42.1±13.2) years, the mean stone burden was (3.9±1.8) cm. The control group included 36 males and 41 females with a mean age of (45.3±13.0) years, the mean stone burden was (3.6±1.5) cm. The numbers of tracts, the time of operation, the drop of hemoglobin, the change of creatine, the time of hospitalization, the stone free rate and major complications were compared between the two groups. The measurement data and numeration data were compared with t test and χ(2) test. Results: There were no significant differences in sex, age, preoperative urinary tract infection, stone type, and stone burden between the two groups (all P>0.05). The proportion of bilateral renal calculus in MSK group was higher (18.2% vs. 0, χ(2)=15.400, P=0.000). There were 159 percutaneous channels were established in MSK group while 90 percutaneous channels were established in control group. Compared with the control group, the operation time ((88.1±37.5) minutes vs. (68.5±30.1) minutes, t=3.543, P=0.000) and hospitalization time ((15.1±8.3) days vs. (10.1±3.6) days, t=4.816, P=0.000) were longer, the creatinine level increased ((101.2±62.6) μmol/L vs. (71.3±23.6) μmol/L, t=3.777, P=0.000), the rate of stone free decreased (27.5% vs. 83.1%, χ(2)=51.840, P=0.000) and the rate of complications increased (29.9% vs. 11.7%, χ(2)=8.114, P=0.004) in MSK group. There was no statistically difference in hemoglobin drop ((12.5±13.2) g/L vs. (13.0±10.9) g/L, t=-0.260, P=0.795). Conclusions: Using PNL for patients of MSK with calculi has a lower stone free rate and a higher complications. It is an effective method for patients of MSK with large and complex calculi.

Abstract
OBJECTIVE To evaluate the risk factors of systemic inflammatory response syndrome (SIRS) in the patients with type 2 diabetes diagnosed with kidney stone after percutaneous nephrolithotomy (PCNL). METHODS In this study, 461 patients with type 2 diabetes who received PCNL in Peking University People's Hospital from June 2006 to December 2015 were reviewed. There were 281 males and 180 females with an average age of 57 years were included, of whom, 137 were diagnosed with SIRS after PCNL. The demographic data, clinical features, and test results were compared between the patients with SIRS and without SIRS, trying to identify the correlation between their clinical characters and the occurrence of SIRS. RESULTS The SIRS was significantly correlated with the patients' preoperative white blood cell counting (×109/L) [7.76 (4.00-17.96) vs. 6.31 (2.00-17.40), P<0.001], preoperational blood glucose level (mmol/L) [7.30 (3.08-19.90) vs. 6.40 (3.42-16.78), P<0.001], operative time (min) [75 (20-270) vs. 60 (20-200), P<0.001], length of stay (d) [12 (2-46) vs. 11 (3-29), P=0.019], staghorn stones [38.8% (33/85) vs. 27.7% (104/376), P=0.042], and preoperational urinary tract infection [36.8% (50/136) vs. 26.6% (81/304), P=0.032]. There was no significant correlation between the SIRS and the patients' age, body mass index, preoperative hemoglobin level, preoperative serum creatinine, and transfusion. In multivariate analysis, abnormal preoperative white blood cell counting (OR=3.194, 95% CI: 1.531-6.666, P=0.002), operative time longer than 60 min (OR=1.635, 95% CI: 1.088-2.456, P=0.018), and preoperational blood glucose level higher than normal 7.1 mmol/L were significantly correlated with the presence of SIRS. CONCLUSION The high level of preoperational blood glucose, abnormal preoperative white blood cell counting, and long operative time were significantly correlated with the presence of SIRS in patients with type 2 diabetes after PCNL.

Abstract
The microbial abundance, the percentage of viable bacteria, and the diversity of bacterial isolates from different regions of a 83.45-m ice core from the Puruogangri glacier on the Tibetan Plateau (China) have been investigated. Small subunit 16S rRNA sequences and phylogenetic relationships have been studied for 108 bacterial isolates recovered under aerobic growth conditions from different regions of the ice core. The genomic fingerprints based on ERIC (enterobacterial repetitive intergenic consensus)-polymerase chain reaction and physiological heterogeneity of the closely evolutionary related bacterial strains isolated from different ice core depths were analyzed as well. The results showed that the total microbial cell, percentages of live cells, and the bacterial CFU ranged from 10(4) to 10(5) cell ml(-1) (Mean, 9.47 x 10(4); SD, 5.7 x 10(4), n = 20), 25-81%, and 0-760 cfu ml(-1), respectively. The majority of the isolates had 16S rRNA sequences similar to previously determined sequences, ranging from 92 to 99% identical to database sequences. Based on their 16S rRNA sequences, 42.6% of the isolates were high-G + C-content (HGC) gram-positive bacteria, 35.2% were low-G + C (LGC) gram-positive bacteria, 16.6% were Proteobacteria, and 5.6% were CFB group. There were clear differences in the depth distribution of the bacterial isolates. The isolates tested exhibited unique phenotypic properties and high genetic heterogeneity, which showed no clear correlation with depths of bacterial isolation. This layered distribution and high heterogeneity of bacterial isolates presumably reflect the diverse bacterial sources and the differences in bacteria inhabiting the glacier's surface under different past climate conditions.

Abstract
To assess the significance of polymorphisms of the genes for angiotensin-converting enzyme (ACE), angiotensin-converting enzyme 2 (ACE2) and urotensin II (UTS2) as risk factors for essential hypertension in two populations from north-western China, we enrolled 198 patients with essential hypertension and 131 healthy controls from the Han population and 120 patients with essential hypertension and 102 healthy controls from the Dongxiang population. Polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism were used to analyse gene polymorphisms. The results provided evidence that genetic variants of UTS2 and ACE2 may play a role in the development of essential hypertension in these populations. Polymorphisms of ACE were not associated with essential hypertension in either population. This is the first report showing that the S89N single-nucleotide polymorphism of the UTS2 gene is associated with essential hypertension.

Abstract
Three ice core samples were collected from the Malan ice core drilled from the Tibetan Plateau, and three 16S rDNA clone libraries by direct amplification from the ice-melted water were established. Ninety-four clones containing bacterial 16S rDNA inserts were selected. According to restriction fragment-length polymorphism analysis, 11 clones were unique in the library from which they were obtained and used for partial sequence and phylogenetic analysis, and compared with 8 reported sequences from the same ice core at depth 70 m. Differences among the samples were apparent in clone libraries. The phylotypes were dominated by the Proteobacteria group, Acinetobacter sp. and Cytophaga-Flavobacterium-Bacteroides (CFB) group. They accounted for 92.5% (Proteobacteria), 100% (Acinetobacter sp.), 34.4% (CFB) and 100% (beta-Proteobacteria) in the clone libraries from the samples at ice depths 35, 64, 70, and 82 m, respectively. The Acinetobacter sp. was only found in the deposition at ice depth 82 m and closely clustered with gamma-Proteobateria. Two members (Malan A-21 and 101) of alpha-Proteobacteria from the sample of 35 m and two (Malan B-26 and 48) of beta-Proteobacteria of 64 m were loosely clustered (< 95% similarity) with known bacteria, represented new genera in ice bacteria.
