Background: The optimal treatment for large impacted proximal ureteral stones remains controversial. The aim of this study was to evaluate the efficacy, safety, and potential complications of mini-percutaneous nephrolithotomy (MPCNL) and retroperitoneal laparoscopic ureterolithotomy (RPLU) in the treatment of impacted proximal ureteral stones with size greater than 15 mm. Methods: A total of 268 patients with impacted proximal ureteral stones greater than 15 mm who received MPCNL or RPLU procedures were enrolled consecutively between January 2014 and January 2019. Data on surgical outcomes and complications were collected and analyzed. Results: Demographic and ureteral stone characteristics found between these two groups were not significantly different. The surgical success rate (139/142, 97.9% vs. 121/126, 96.0%, P = 0.595) and stone-free rate after 1 month (139/142, 97.9% vs. 119/126, 94.4%, P = 0.245) of RPLU group were marginally higher than that of the MPCNL group, but there was no significant difference. There was no significant difference in the drop of hemoglobin between the two groups (0.8 ± 0.6 vs. 0.4 ± 0. 2 g/dL, P = 0.621). The mean operative time (68.2 ± 12.5 vs. 87.2 ± 16.8 min, P = 0.041), post-operative analgesics usage (2/121, 1.7% vs. 13/139, 9.4%, P = 0.017), length of hospital stay after surgery (2.2 ± 0.6 vs. 4.8 ± 0.9 days, P < 0.001), double J stent time (3.2 ± 0.5 vs . 3.9 ± 0.8 days, P = 0.027), time of catheterization (1.1 ± 0.3 vs. 3.5 ± 0.5 days, P < 0.001), and time of drainage tube (2.3 ± 0.3 vs . 4.6 ± 0.6 days, P < 0.001) of MPCNL group were significantly shorter than that of the RPLU group. The complication rate was similar between the two groups (20/121, 16.5% vs . 31/139, 22.3%, P = 0.242). Conclusions: MPCNL and RPLU have similar surgical success and stone clearance in treating impacted proximal ureteral stones greater than 15 mm, while patients undergoing MPCNL had a lower post-operative pain rate and a faster recovery.

Neurofibromatosis type 1 (NF1) is an inherited autosomal dominant disorder. Haematoma is an unusual complication of neurofibromatosis and extremely rare in the maxillofacial region. A case of haematoma in NF1 of the left face is presented. MR images of acute haematoma in NF1 and radiographic features of the mandible are described. Stenosis of the internal jugular vein was noted in MR angiography (MRA). Surgical resection of the tumour and evacuation of blood clots were performed. Histological and immunohistochemical examination demonstrated that the neurofibroma tumour cells infiltrated the mural layer of vessels without malignant translation. MRI is a good choice for depicting haematoma in neurofibromatosis. Intratumour haemorrhage may result from the infiltration of vessels into the lesion and minor trauma on the affected area.

This study was based on the perspectives of tourists, with data obtained through a questionnaire survey of users of the Kaiyuan Temple Scenic Area in Quanzhou City, Fujian Province, China. Through statistical evaluation and principal component analysis, the data collected from 351 questionnaires were analyzed, and five common factors affecting tourists’ perceptions were obtained: spatial structure, functional structure, utility plants, heritage characteristics and sensory characteristics. Through data analysis and research, the following conclusions were drawn: (1) most tourists have high expectations in terms of the overall layout of the temple garden plant landscape; (2) they like eye-catching and interesting plants and comfortable spaces for recreation and leisure; (3) they pay attention to the health-giving properties of plants; (4) tourists like it when the temple garden plant landscape includes a diverse range of plant forms while maintaining distinctive regional characteristics; and (5) tourists find bright flowers and aromatic plants relaxing and mood-enhancing, functioning to promote interaction between the temple landscape and tourists. The findings of the study can therefore be used as theoretical guidance for the design of urban temple garden plant landscape construction that meets the needs of tourists.

Working memory has been considered an active buffer for processing perceptual representations in a progressive manner, integrating information involuntarily to form structured mental representations. The automatic integration of objects' physical features in working memory has been well documented, although its social aspect remains unknown. The current study examines whether working memory would automatically process social information, that is, extract social information from memory content to form a higher-level social representation. Through four experiments, we demonstrate that participants could spontaneously infer personality traits when required to hold the social information implying others' traits in working memory, without the explicit goal of trait inference or awareness of the inference processes. Results show that participants mistook the memorized words for inferred trait words; such "errors" were then accumulated and amplified when the information was transmitted from person to person, during which the social information was briefly stored in working memory and reproduced after a short time. These findings indicate that working memory may automatically integrate social information into hierarchically structured mental representations.

Background: Outbreaks of hand-foot-and-mouth disease (HFMD) have occurred in many parts of the world, particularly in China. The disease usually has ease of communicability and a higher risk of developing severe complications leading towards death. In this study, we aim to evaluate the clinical features, laboratory examination, and treatment for serious cases of HFMD, using a retrospective analysis based on clinical data. Methods: We report the clinical features of 22 deceased patients with confirmed diagnoses of HFMD, who presented to hospitals in the Shanxi Province of China between June 2010, and August 2012. Demographic, clinical and laboratory data from inpatients were collected. Results: The findings of this report showed that Enterovirus 71 (EV71) is the causative agent of HFMD, particularly in male children under the age of 3. Some common symptoms including fever, rash, and malfunctioning of respiratory, circulatory, and neurologic systems were observed in all studied patients. However, circulatory failure was the most important cause of death for these patients. Furthermore, increases in the peripheral white blood cell count (>15 × 10 9 /L) and the blood sugar level (>8.3 mmol/L) are among the important reference indices for serious cases. Hence, on time provision of respiratory and circulatory supports enhance the efficiency of a comprehensive treatment strategy. Conclusion: HFMD, characterized by high fever, convulsions, mental fatigue, vomiting and cold limbs, carries a high risk of death. Earlier identification of higher-risk infants might allow for more rapid intervention. Our findings suggest that the peripheral white blood cell count (>15 × 10 9 /L) and the blood sugar level (>8.3 mmol/L) should be considered as warning signs while, clinicians manage surges of children diagnosed with HFMD to avoid death.
