A digital customer service platform in hospital wards is equivalent to a platform to provide convenient, value-added and fine bedside services to in-patients as customers (customers admitted into hospitals and those for physical check inclusive).These services are provided via a set-top box and/or TV set installed with corresponding software.This platform supports such services as bills check, food order, non-medical services, VOD, games and entertainment, as well as commercial services from outside the hospital This article introduces the system structure, functionality, as well as the outcome and value of this platform, pointing out that this platform is an innovation of information technology, and that of hospital management and service mode as well

OBJECTIVE This objective of this study was to investigate intranasal anatomic abnormalities in cases of contact point headaches caused by contact between the nasal septum and the lateral nasal wall,as well as the clinical outcomes in these cases treated by endoscopic sinonasal surgery. METHODS A retrospective review was performed on 58 cases that met the criteria of having contact points between the septum and the lateral nasal wall, as demonstrated by CT scans of the sinuses and endoscopic examinations. These patients underwent surgical intervention in order to correct the contact points. They were re-evaluated for clinical parameters three months after the surgical correction of their anatomic abnormalities. RESULTS Abnormal nasal septa, enlarged turbinates and other anatomic abnormalities were the most common findings in contact point headaches. Fifty-eight patients underwent surgical correction of intranasal anatomic abnormalities. After follow-up periods of 3-18 mouths, 32 patients were cured, 23 were relieved to an extent, and 3 did not benefit. A significant decrease in the severity and frequency of headaches was noted after surgery. CONCLUSION Pressure from mucosal contact between the septum and lateral nasal wall mucosa is the key cause of contact point headaches, as seen in CT scans of the sinuses and endoscopic examinations. Clinically significant pain may improve after surgical correction of intranasal anatomic abnormalities.

Objective To investigate ecological isolation between Oncomelania hupensis snail populations in hilly regions and marshland and lake regions in Yuanjiang valley, Changde City, Hunan Province, and to unravel its underlying mechanisms. Methods Taoyuan County, Shimen County, Linli County and Lixian County in Changde City were selected as snail sampling sites in hilly regions, and Lixian County, Jinshi City, West Lake Administration District, Hanshou County and Dingcheng District were selected as snail sampling sites in marshland and lake areas. Cytochrome C oxidase 1 (cox 1) gene was amplified in snail samples and sequenced. The genetic sequences of O. hupensis snails were aligned using the software MEGA 11, and the haplotypes of O. hupensis snails were determined using the software DNASP 5.10.01. The phylogenetic tree was generated using Bayesian inference with the software MrBayes 3.2, and analysis of molecular variance (AMOVA) was performed to analyze the source of genetic divergence and estimate the genetic divergence index (F_ST) among snail populations with the software Arlequin 3.5.2.2. The genetic barrier among 11 O. hupensis snail populations was estimated using the Monmonier algorithm of adegenet toolkit in R package. The settings with “land in winter and water in summer” in the Yuanjian River section were divided into two categories according to the upstream and downstream, and the areas with “land in winter and water in summer” in the upstream and downstream were transformed into raster data, and then loaded into the software Fragstats 4 for analysis of landscape indicators. The trends in changes of digital elevation were extracted from the Yuanjiang River section based on the digital elevation model, and made three-dimensional visualization using the R package. Results The mitochondrial cox 1 gene were amplified in 165 O. hupensis snais from 11 sampling sites and sequenced, and a total of 152 valid gene sequences were obtained, with 46 haplotypes or 9 populations determined. No haplotype was shared in snails between Taoyuan County and Dingcheng District and Hanshou County along the downstream of the Yuanjiang River. The total area of settings with “land in winter and water in summer” was 617.66 hm² in the upsteram of the Yuanjiang River, which consisted of 473 patches, with each patch measuring 1.31 hm², the largest area index of 0.735 2, the landscape division index of 0.999 9, and the landscape shape index of 45.293 7. The total area of settings with “land in winter and water in summer” was 9 956.92 hm² in the downstream of the Yuanjiang River, which consisted of 771 patches, with each patch measuring 12.91 hm², the largest area index of 97.839 9, the landscape division index of 0.042 7, and the landscape shape index of 7.249 6. The area of settings with “land in winter and water in summer” was much larger in the downstream than that in the upstream of the Yuanjiang River, and the stronger landscape connectivity and non-remarkable alteration of riverbed elevation provided suitable habitats for snail breeding. Conclusion The hydrological and environmental characteristics of the upstream of the Yuanjiang River restrain the breeding and spread of O. hupensis, resulting in ecological isolation between Oncomelania hupensis in Taoyuan County and those in the downstream of Yuanjiang River.
