Objective To develop a new instrument to assess swallowing function which will be suitable for nurses to screen dysphagia in the patients with stroke.MethodsItems closely related to symptoms and signs of dysphagia were found with literature review, forming a preliminary instrument. All items retrieved were selected and modified by experts interview and a pilot study in patients with stroke. Then, a clinical nursing swallowing assessment tool (CNSAT) was formulated.ResultsTotally, seven items of symptoms and signs related to dysphagia in patients with stroke were found with literature review. All the seven items retrieved were selected again by experts interview and finally a CNSAT was formed with six modified items by a pilot study in 10 patients with stroke, each item with four choice based on its severity of their symptoms and signs.ConclusionCNSAT is a simple, convenient and safe instrument and suitable for nurses to assess swallowing function of patients with stroke.

Aim To investigate the effect of DHA on NGF-induced neuronal differentiation of PC12 cells and explore the possible mechanism via regulating BMP pathway. Methods PC12 cells were treated with 100μg·L-1 NGF and 100 μg·L-1 NGF + 10 μmol· L-1 DHA for 3, 6 and 9 days respectively. The length and number of neurite were detected by immunofluores-cenc. DHA content was analyzed by gas chromatogra-phy in all groups. The protein expression of BMP4, BMP7 , BMPR-II and p-Smad 1/5/8 was determined by Western blot. Results The length of total primary neurite in NGF+DHA groups was obviously increased, longer than that in NGF group; DHA content in 10μmol · L-1 DHA group was higher than that in the control group;NGF+DHA groups also unregulated the protein expression of BMP4 , BMP7 , BMPR-II and p-Smad 1/5/8 . Conclusion DHA promotes NGF-in-duced neuronal differentiation in PC12 cells, which may be associated with the upregulation of BMP path-way protein.

Objective To observe the clinical parameters, self-management, and compliance in peritoneal dialysis (PD) patients before and during Spring Festival, and to describe holiday syndrome in PD patients.Methods We prospectively observed PD patients with regular follow-up in our center before Chinese Spring Festival (January 8-February 7, 2016) and during Chinese Spring Festival (February 8-March 8, 2016).Demographic and clinical characteristics, self-management, and compliance with its influencing factors were collected by face-to-face method in outpatient care.Results Totally 130 PD patients were enrolled.The average age was (58.5±15.4) years, and women accounted for 53.1％.The primary diagnosis was diabetic kidney disease (32.3％), followed by primary glomerulonephritis (26.2％).Fourteen patients (10.8％) received automated peritoneal dialysis (APD), and most of the remaining patients chose continuous ambulatory peritoneal dialysis (CAPD,73.8％), with a median dialysis age of 34 months.During the 4-week followed-up, the appetite was stable, while the serum phosphate and pre-albumin increased [(1.5±0.4)mmol/L vs.(1.6±0.4)mmol/L, P=0.025;325.3 (272.2,355.1)mmol/L vs.326.0(284.2,376.5)mmol/L, P<0.01, respectively].No difference was observed in edema, dyspnea, and nighttime lying flat.However, the weight elevated significantly [(61.3±13.9)kg vs.(63.4±13.0)kg, P=0.002], with the median peritoneal ultrafiltration volume increased from 783.3 ml to 900.0 ml (P=0.005).During the holiday, the incidences of dialysis-related infections were unchanged, while the incidences of digestive system comorbidities increased significantly (5.4％ vs.13.8％, P=0.021).As for the compliance, 8 patients reduced their PD cycles during the holiday, which was more frequent than before holiday (P=0.018).One patient changed his PD pattern, and 6 patients did not follow the medication orders.Demographic characteristics such as gender, age, and marriage conditions were not associated with the compliance.Conclusions Holiday syndrome remarkably affects PD patient''s volume load, metabolism, and compliance.Poor self-management of PD patients during holidays needs further concern.

Objective To investigate the quality of the chronic kidney information found on websites. Methods Three search engines were searched for relevant chronic kidney websites. The independent raters use HON code(The Health On Net Code of Conduct for medical and health Web sites, HON code) and DISCERN instrument to evaluate the chronic kidney websites in Chinese. Results A total of 18 websites were included into our study.The overall mean quality of HON code was 3.6±1.6.The overall mean quality of DISCERN instrument was 32.3 ± 10.8. In the research site, the number of sites built by nonprofits accounted for only 5.6%(1/18). Conclusions The information quality on chronic kidney found online was of poor.The main reason is health websites contain lots of advertisement,and it is rare that non-profit websites can provide medical information which is suitable for general public,the overall reliability is poor,Chinese health websites need to put efforts on developing the quality of health information.

OBJECTIVETo evaluate the efficacy of combined newborn hearing screening and deafness-related mutation screening.

METHODSEleven thousand and forty-six newborn babies were screened with otoacoustic emission, automatic auditory brainstem response and genetic testing using a standard protocol. Common mutations of three deafness-related genes have included GJB2 (c.235delC, c.299-300delAT), mtDNA 12srRNA (c.1494C>T, c.1555A>G) and SLC26A4 (c.2168A>G, c.IVS7-2A>G).

RESULTSThe detection rate for hearing loss in the first-step screening was 0.81% (90/11,046). 513 individuals were found to carry one or two mutant alleles, which gave a carrier rate of 4.64% (513/11,046). Five hundred and eighty-four newborns were positive for hearing screening and genetic screening. Among these, 19 have failed both tests, 71 have failed hearing screening, and 494 have failed genetic screening. The combined hearing and genetic screening has given a positive rate of 5.29%.

CONCLUSIONNeither hearing screening nor genetic screening is sufficient to identify individuals susceptible to auditory disorders. Combined used of these methods can improve the rate of detection.

Background: Granular cell tumor (GCT) is an uncommon tumor, and gastrointestinal tract GCT is even more rare. Aims: To investigate the clinicopathological characteristics, treatment and prognosis of gastrointestinal tract GCT. Methods: Nine cases of gastrointestinal tract GCT from January 2017 to June 2021 at the 903rd Hospital of Joint Logistics Support Force, PLA and Jinhua Municipal Central Hospital Medical Group were retrieved. The clinical data, histopathological characteristics, treatment, and prognosis were retrospectively analyzed. Results: In the 9 patients with gastrointestinal tract GCT, ratio of male to female was 2:1, age at diagnosis was 19-60 years, with a median age of 52 years. Six GCT were found in esophagus, 2 in colorectum and 1 in anus. Endoscopic results showed submucosal protrusion or sessile polyps ranging in size from 2-12 mm with a median of 5 mm. Histology results showed that tumors were located in mucosa and/or submucosa, arranged in solid sheets or nests, with an infiltrative margin and inflammatory infiltrates. Tumor cells were mainly plump and polygonal with abundant cytoplasm and eosinophilic granules. Nuclei were small, the nuclear-cytoplasmic ratio was very low. Mitotic figure was rare. Immunohistochemistry results showed that S100 and CD68 proteins were positive in all patients, SOX10, CD56, Calretinin and Syn were positive in some patients, and CKp, Desmin, SMA, CD117, CD34, Dog1, and α-inhibin were negative in all patients. Esophageal and colorectal GCT patients received endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD). The anal GCT patient underwent local resection. Recurrence or metastasis were not observed during 9-53 months of follow-up. Conclusions: Gastrointestinal tract GCT is rare with non-specific clinical symptoms and submucosal protrusion or sessile polyps under endoscopy. Gastrointestinal tract GCT has special pathomorphology and immunophenotype. EMR or ESD is recommended for small and superficial lesions. Long-term follow-up should be performed.
