Abstract
Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults. Patients often complain of hematuria, flank pain, or abdominal pain. Complications of lymphangioma have been reported to include infection, ruputure, or hemorrhage. There are three types of lymphangioma commonly identified: capillary, cavernous, and cystic. Cystic type is the one commonly found intra-abdominally or retroperitoneally, and may be uniloculated or multiloculated. All these perirenal tumors have a very low incidence, make it difficult to diagnose. Differential diagnosis must be performed with the primary renal lymphoma, urinoma, polycystic kidney, teratoma, both benign and malignant tumors, etc. Endoscopic ultrasound guided fine needle aspiration is recommended in some literatures, which may help make diagnosis and further guide subsequent therapeutic strategy. Regarding treatment, surgical excision can be performed via either laparotomy or laparoscopy. And injection of sclerosants into lympahgioma has been described in the literature in nonsurgical candidates. The optimal definitive treatment is total surgical excision. Despite being rare, the tumor has an excellent prognosis. Here, we report a case of a 48-year-old woman with a left renal mass found in an abdominal ultrasonography during a health checkup. In the case presented, abdominal ultrasonography and magnetic resonance urography (MRU) revealed an approximately 11.3 cm×10.6 cm×12.8 cm multilocular cystic mass in the left perirenal space. There was no history of bowel or bladder complaint, either previous illness episodes. Full blood count and kidney function tests were within normal limits. Laparoscopic surgical removal of the cyst was accomplished without incident. A benign cystic perirenal lymphangioma was diagnosed on histology and confirmed with immunohistochemical stains. One month after the surgery the ureteral stent was removed. The patient was free of disease after a 3-month follow-up period. We report the case and discuss the management of perirenal lymphangiomatosis with a literature review.

Abstract
OBJECTIVE To analyze the efficiency of ureteroscope and biopsy in the diagnosis of tumor grade, muscle-invasiveness and multifocality in suspected upper tract urinary carcinoma (UTUC) patients in order to find out whether it can be used in the risk stratification of UTUC patients. METHODS A retrospective study of 76 UTUC patients who underwent preoperative ureteroscope and/or biopsy and received radical nephroureterectomy in Peking University Third Hospital during January 2014 to December 2016 was undertaken. RESULTS In this study, 76 patients were included. There were 31 males (40.8%), and 45 females (59.2%). The median age was 64.5 years (31-88), and 51 patients had the symptom of hematuresis. The tumor was located in renal pelvis in 39 patients, and in ureter in 37 patients. Post-operative pathology confirmed that all the 76 patients included in this study suffered from UTUC, of whom 21 (21.6%) were of low-grade, 51 (67.1%) were of high-grade, 4 (5.3%) were undetermined, and 47 (61.9%) patients were muscle-invasive, and 27 (35.5%) were not, and 2 (2.6%) were undetermined. Among the 50 patients, in whom the grade of the tumor could be diagnosed by biopsy, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for low-grade tumor was 88.2%, 69.7%, 76.0%, 60.0% and 92.0%, respectively. Among the 27 patients, in whom the muscle-invasiveness could be diagnosed by biopsy, 5 patients were diagnosed with muscle-invasiveness, all confirmed by pathology after surgery and 22 patients were diagnosed with none muscle-invasiveness, turned out to be 50% muscle-invasive and 50% none-muscle invasive after surgery. The accuracy was 59.3%. The accuracy of ureteroscopic biopsy to diagnosis multifocality was 61.0%. On univariate analysis, biopsy grade was associated with postoperative pathology (P=0.001), while gender, age, side, body mass index (BMI), hematuresis, preoperative estimated glomerular filtration rate (eGFR), hydronephrosis, tumor size, location, multifocality and sessile were not associated with postoperative pathology grade. Biopsy grade (P=0.02), preoperative eGFR<90 mL/(min×1.73 m2)(P=0.025) and tumor located in pelvis (P=0.049) were associated with muscle invasiveness. Gender, age, side, BMI, hematuresis, hydronephrosis, tumor size, multifocality and sessile were not significantly associated with muscle invasiveness. CONCLUSION Ureteroscope and biopsy can assist risk stratification in upper tract urothelial carcinoma patients.

Abstract
BACKGROUND An unexpected, large dengue outbreak, spreading to 20 cities of Guangdong province, occurred in July 2014. Considering the overwhelming influence of this seasonal epidemic, whether this dengue virus outbreak has an significant impact on the blood donors of the ajacent areas in Guangdong requires at least a preliminary investigation. Liuzhou City of Guangxi was chosen as a good representative of the neighbouring geographical location of the dengue virus (DENV) outbreak areas in this research. We therefore investigated qualified blood donations during potential dengue epidemic seasons and thus provided critical information for public health and donation policy making. METHOD A total of 1685 donations from 2013 to 2014 were collected at the Guangxi blood centre. Anti-DENV testing was performed using enzyme-linked immunosorbent assay (ELISA). Dengue IgG indirect ELISA and Dengue IgM capture ELISA were used to detect anti-DENV IgM and IgG. Repeat-reactive samples with ELISA test and 1685 donations with 421 pools were screened for dengue RNA by reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) using an in-house assay. RESULTS There was a total of 13 seropositive donors, including 6 IgM seropositive and 7 IgG seropositive. The total seropositive rate was 0·78%, with IgM 0·36% and IgG 0·42%. Seropositive donors were identified mostly between April and November, with a peak in November. .All samples in reactive pools and individual seropositive samples were negative in the follow-up RT-PCR test. CONCLUSION Our results suggested that the Guangdong dengue outbreak had limited impact on blood safety in surrounding areas under our current testing system.

Abstract
Objective:To investigate the changes of speech and voice acoustics in patients with thyroid disease before and after operation, get objective values, and conducive to guiding the clinical diagnosis and treatment and recurrent laryngeal nerve protection. Method:A total of 216 patients undergoing thyroid surgery from October 2015 to October 2016 were treated with TVQ and GRBAS at 1 day before surgery, 1 week, 1 month, and 3 months postoperatively to phonological assessment, and Praat software was used to collect and analyze the acoustic acoustics index for preoperative and postoperative comparative analysis. Result:All patients did not damage the recurrent laryngeal nerve, unilateral or bilateral thyroid subtotal resection (no exploration of recurrent laryngeal nerve) in patients with postoperative speech and voice index F0 was decreased at 1 week after surgery (P<0.05), the other indicators did not change significantly; difference was found out in single-sided total thyroidectomy+ipsilateral central area lymph node dissection, bilateral thyroidectomy+unilateral central area lymph node dissection (exploration of unilateral recurrent laryngeal nerve) in patients with TVQ, GRBAS and F0, HNR after surgery 1 week compared with preoperative (P<0.05), However, there was no significant difference 3 months; TVQ, GRBAS and F0, HNR were significantly changed in patients with bilateral thyroidectomy+bilateral central lymph node dissection (revealed bilateral recurrent laryngeal nerve) at 1 week after operation (P>0.05). F0 and HNR were lower than those before operation, and the patients were treated with Jitter and Shimmer. The patients were treated with TVQ, GRBAS, Jitter and Shimmer before operation, however, the majority of patients' TVQ, GRBAS, Jitter, Shimmer can be restored to preoperative level after surgery 3 months (P>0.05). Conclusion:The appearance of speech and voice problems in patients after thyroid surgery may increase with the expansion of the surgical range, the change in speech and voice after neck lymph node dissection is reversible.

Abstract
UNLABELLED Magnesium has a key role in osteoporosis and could enhance implant osseointegration in osteoporotic patients. Titanium implants impregnated with Mg ions were installed in the tibia of ovariectomized rats. The release of Mg induced a significant increase of bone formation and the expression of anabolic markers in the peri-implant bone. INTRODUCTION The success of endosseous implants is highly predictable in patients possessing normal bone status, but it may be impaired in patients with osteoporosis. Thus, the application of strategies that adjuvate implant healing in compromized sites is of great interest. Magnesium has a key role in osteoporosis prevention and it is an interesting candidate for this purpose. In this study, the cellular and molecular effects of magnesium release from implants were investigated at the early healing stages of implant integration. METHODS Osteoporosis was induced in 24 female rats by means of ovariectomy and low-calcium diet. Titanium mini-screws were coated with mesoporous titania films and were loaded with magnesium (test group) or left as native (control group). The implants were inserted in the tibia and femur of the rats. One, 2 and 7 days after implantation, the implants were retrieved and histologically examined. In addition, expression of genes was evaluated in the peri-implant bone tissue at day 7 by means of quantitative polymerase chain reactions with pathway-oriented arrays. RESULTS The histological evaluation revealed that new bone formation started already during the first week of healing for both groups. However, around the test implants, new bone was significantly more abundant and spread along a larger surface of the implants. In addition, the release of magnesium induced a significantly higher expression of BMP6. CONCLUSIONS These results provide evidence that the release of magnesium promoted rapid bone formation and the activation of osteogenic signals in the vicinity of implants placed in osteoporotic bone.

Abstract
Extracellular matrix (ECM) is a system used to model the design of biomaterial matrices for tissue regeneration. Various biomaterial systems have been developed to mimic the composition or microstructure of the ECM. However, emulating multiple facets of the ECM in these systems remains a challenge. Here, a new strategy is reported which addresses this need by using silk fibroin and chitosan (CS) nanocomposite materials. Silk fibroin was first assembled into ECM-mimetic nanofibers in water and then blended with CS to introduce the nanostructural cues. Then the ratios of silk fibroin and CS were optimized to imitate the protein and glycosaminoglycan compositions. These biomaterial scaffolds had suitable compositions, hierarchical nano-to-micro structures, and appropriate mechanical properties to promote cell proliferation in vitro, and vascularization and tissue regeneration in vivo. Compared to previous silk-based scaffolds, these scaffolds achieved improvements in biocompatibility, suggesting promising applications in the future in tissue regeneration.

Abstract
Objective: To investigate the relationship between optic nerve sheath diameter (ONSD) and volume status of patients after cardiac surgery. Methods: A total of consecutive 56 patients who were treated in Critical Care Unit in Peking Union Medical College Hospital after open heart surgery from January to August 2015 were screened in this study. Central venous pressure (CVP) and 72 h net fluid balance were monitored. ONSD and diameter of inferior vena cava (IVC) were measured by ultrasound. Results: A total of 44 patients were finally included in the study. The postoperative baseline ONSD was (5.31±1.96)mm, compared to (5.07±1.77)mm after 72 h treatment, with ΔONSD(0.22±0.21)mm. Baseline and post-treatment at 72 h CVP were (11.98±4.09)mmHg and (8.95±4.02)mmHg respectively. IVC dropped from (19.75±4.12)mm to (17.11±4.68)mm. ΔONSD and ΔCVP were significantly correlated (r=0.422, P<0.05), ΔONSD and net fluid balance (NFB) at 72 h were significantly correlated (r=-0.388, P<0.05). While ΔONSD were significantly correlated with ΔIVC (r=0.423, P<0.05), ΔCVP and ΔIVC were also significantly correlated (r=0.391, P<0.05). Conclusion: The change of ONSD in patients after cardiac surgery is related to the change of volume status. Therefore ONSD is helpful to estimate brain edema, not only could be a potential index to evaluate volume status, but also be used to guide improving prognosis after cardiac surgery.

Abstract
OBJECTIVE Isolated systolic hypertension (ISH) is the most important risk factor for ischemic stroke. Genetic variants influencing hypertension can also be risk factors for ischemic stroke. Here, we examined the how single nucleotide polymorphisms (SNPs) associated with blood pressure impact the risk for ischemic stroke. PATIENTS AND METHODS We selected 300 ischemic stroke patients and 300 controls. Then, we genotyped three single nucleotide polymorphisms associated with systolic hypertension in both groups. RESULTS Logistic regression analysis showed that the rs11099098 genotype was associated with a significantly decreased risk of IS (Dominant model: OR = 0.55, 95% CI = 0.37-0.82, p = 0.003). Two other SNPs, rs880315 and rs11072518, showed a trend towards association with stroke risk, but did not reach statistical significance. CONCLUSIONS Our study suggests that genetic variants in systolic pressure-related genotypes may contribute to the etiology of ischemic stroke.

Abstract
Rodents act as an indicator for evaluation of environment contaminations and public health risks caused by parasites. A survey of parasites in wild rodents was conducted in 14 villages in Xijin County, where alveolar echinococcosis by Echinococcus multilocularis is epidemic. In total, 72 rodents including 25 mice, 16 Citellus dauricus (Daurian ground squirrel), 12 squirrels and 19 mole rat (Myospalax fontanieri) were captured. Infections (2.8%) of Taenia taeniaeformis, which is transmitted mainly between mice and cats, were found in mice in Wangping (WP) and Miaoping (MP) villages, but other cestodes' infections were not observed. WP and MP isolates were principally similar in morphology but, unlike WP isolate, MP isolate had no hooks on the scolex. Using 18S rRNA as a biomarker, the phylogenetic analysis showed that WP and MP isolates grouped together with European and Asian isolates and formed a separate cluster. These results highlights the prevalence of T. taeniaeformis in cats or/and dogs and a risk of opportunistic infections in human populations.

Abstract
Tricyclic indolines are common in both natural products and synthetic chemical probes. In this study we demonstrated that enantiomerically pure tricyclic indolines can be prepared from an inexpensive commercially available chiral starting material, pyroglutamic acid. The synthesis features a highly diastereoselective gold-catalyzed cyclization of alkyne-tethered indoles and subsequent diastereoselective reductive ring-opening reaction. Using this approach, we synthesized analogs of our previously discovered tricyclic indoline probes that possess antibacterial and resistance-modifying activity. The biological activity against methicillin-resistant Staphylococcus aureus (MRSA) of these analogues was evaluated and reported. The synthetic approach reported may be leveraged in the future to prepare diastereopure chemical probes for the determination of biological targets for drug discovery.

Abstract
Research indicates that after EGFR-tyrosine kinase inhibitors (EGFR-TKIs) treatment of non-small cell lung cancer (NSCLC), patient immune function significantly improved, and that circulating tumor cells (CTCs) measurements and peripheral blood epidermal growth factor receptor (EGFR) mutation data can guide TKIs treatment. Sixty-six advanced NSCLC patients treated with TKIs were enrolled and CTCs, EGFR expression, T cell subsets and natural killer (NK) cells in peripheral blood were measured using flow cytometry before and after treatment and assessed with respect to patient prognosis. CTCs and EGFR expression were negatively correlated with cellular immune function and immune recovery after EGFR-TKI treatment. Thus, CD4+/ CD8+ ratios and NK cells may be useful prognostic indicators for advanced NSCLC patients who receive TKIs treatment.

Abstract
OBJECTIVES Mesenchymal stem cells (MSCs) have been widely used for regenerative medicine. Traditionally, the procedures of MSC isolation are usually invasive and time-consuming. Urine is merely a body waste, and recent studies have suggested that urine represents an alternative source of stem cells. We, therefore, determined whether the possibility of isolating mesenchymal-like stem cells was practical from human urine. METHODS A total of 16 urine samples were collected from pediatric patients. Urine-derived cells were isolated, expanded, and identified for specific cell surface markers using flow cytometry. Cell morphology was observed by microscopy. Osteogenic and adipogenic differentiation potential were determinded by culturing cells in specific induction medium, and assessed by alkaline phosphatase and oil red O stainings, respectively. RESULTS Clones were established and passaged successfully from primary cultures of urine cells. Cultured urine-derived cells at passage 3 were fusiform and arranged with certain directionality. Urine-derived cells at passage 5 displayed expressions of cell surface markers (CD29, CD105, CD166, CD90, and CD13). There was no expression of the general hematopoietic cell markers (CD45, CD34, and HLA-DR). Under in vitro induction conditions, urine-derived cells at passage 5 were able to differentiate into osteoblasts, but not adipocytes. CONCLUSIONS Urine may be a noninvasive source for mesenchymal-like stem cells. These cells could potentially provide a new source of autologous stem cells for regenerative medicine and cell therapy.

BACKGROUND Cadmium (Cd) is an environmental and industrial pollutant that induces a broad spectrum of toxicological effects, influences a variety of human organs, and is associated with poor semen quality and male infertility. Increasing evidence demonstrates that Cd induces testicular germ cell apoptosis in rodent animals. However, the specific effect of Cd exposure on autophagy in germ cells is poorly understood. METHODS We investigate the role of high-mobility group box 1 protein (HMGB1), a ubiquitous nuclear protein, on Cd-evoked autophagy in a mouse spermatocyte cell line (GC-2spd). RESULTS Our data have shown that autophagy was significantly elevated in GC-2spd cells exposed to Cd. Furthermore, there was a reduction in rapamycin (RAP)-mediated apoptosis. In addition, Cd exposure reduced cell viability, which is an effect that could be significantly inhibited by RAP treatment. These results indicate that autophagy appears to serve a positive function in reducing Cd-induced cytotoxicity. In addition, HMGB1 increased coincident with the processing of LC3-I to LC3-II. Thus, the upregulation of HMGB1 increases LC3-II levels. CONCLUSIONS Our data suggest that HMGB1-induced autophagy appears to act as a defense/survival mechanism against Cd cytotoxicity in GC-2spd cells.
