PIEZO2 expression is an independent biomarker prognostic for gastric cancer and represents a potential therapeutic target.

Gastric cancer (GC) is one of the most prevalent malignant tumors of the gastrointestinal system in the globe. The effect of PIEZO2 on the immune function and pathological features of gastric cancer remains to be explored. The Online database of cancer genes and GSE54129 have been used to analyze the clinical characteristics of PIEZO2 expression. We looked at the relationship between PIEZO2 and the immune systems of GC patients. The TIDE algorithm was used to explore the value of PIEZO2 in immunotherapy. Investigated the enrichment of PIEZO2 gene ontology and associated signal pathways using Online gene databases. The results show that overexpression of PIEZO2 was identified as an independent risk factor for patients with GC who had poor overall survival. Individuals may have a better prognosis if they had poorly differentiated GC and increased PIEZO2 expression (P < 0.05). We demonstrated a strong correlation between PIEZO2 and immune cells. The majority of immune checkpoint and immunological-related genes were associated with PIEZO2 expression. And PIEZO2 might be used as an immunotherapy target. Finally, the differential PIEZO2 genes in GC were mostly implicated in the processes of inflammation, immunological response, and tumor metastasis, according to functional analysis. PIEZO2 has a negative correlation with cell stemness and mutation levels in patients with GC and a positive correlation with immune cell infiltration and gene expression in the tumor microenvironment. These findings point to PIEZO2 as a potential new immunotherapy target of GC.

Association between glycemic traits and melanoma: a mendelian randomization analysis.

Background: The causation of Glycemic Traits and risks of Melanoma remains unknown. We used Mendelian Randomization (MR) to assess the links between Glycemic Traits and Melanoma. Method: Pooled data from Genome-Wide Association Studies (GWAS) were utilized to examine the relationships that exist between Fasting Insulin (n = 26), 2-h Glucose (n = 10), Fasting Glucose (n = 47), HbA1c (n = 68), and Type-2 Diabetes (n = 105) and Melanoma. We evaluated the correlation of these variations with melanoma risk using Two-Samples MR. Result: In the IVW model, Fasting Glucose (OR = 0.99, 95%CI = 0.993-0.998, p < 0.05, IVW), Type-2 Diabetes (OR = 0.998, 95%CI = 0.998-0.999, p < 0.01, IVW) and HbA1c (OR = 0.19, 95%CI = 0.0415-0.8788, p < 0.05, IVW) was causally associated with a lower risk of Melanoma. In all models analyzed, there was no apparent causal relationship between Fasting Insulin and Melanoma risk. There was no obvious causal difference in the IVW analysis of 2-h Glucose and Melanoma, but its p < 0.05 in MR Egger (OR = 0.99, 95%CI = 0.9883-0.9984, p < 0.05, MR Egger), and the direction was consistent in other MR analyses, suggesting that there may be a causal relationship. Conclusion: The results of this study suggest that a higher risk of Fasting Glucose, Type-2 Diabetes, 2-h Glucose, and HbA1c may be associated with a lower risk of Melanoma. However, no causal relationship between fasting insulin and melanoma was found. These results suggest that pharmacological or lifestyle interventions that regulate plasma glucose levels in the body may be beneficial in the prevention of melanoma.

[A pilot study of ocular diseases screening for neonates in China].

OBJECTIVE: To explore the clinical strategies for the screening of newborn eye diseases and obtain information concerning the incidence of newborn ocular diseases. METHODS: Newborns in a baby-friendly nursery were evaluated for mass screening of eye diseases 2 to 7 days after birth (including reaction to light stimulation, external ocular examination and test for pupil red reflex) and those with abnormalities were subjected to diagnostic examination (external ocular examination with a hand-held slit-lamp, pupil red reflex and mydriatic examination). Newborns in neonatal intensive care unit (NICU) were subjected to screening 5 to 14 days after birth and then, together with those with high risk factors, received a comprehensive examination for screening and diagnostic purposes. The suspected cases were referred to department of ophthalmology for definite diagnosis. RESULTS: Among the 15,398 (91.65%) newborns who were enrolled the screening program, 12 different eye diseases (involving 1266 cases) were detected, with a prevalence of 8.22%. Of these eye diseases, 7 were congenital ocular diseases, involving 809 cases (5. 254%) and including congenital ptosis in 2 cases (0.013%), congenital corneal opacity in 6 cases (0.039%), persistent pupillary membrane in 724 cases (4.702%), congenital cataract in 15 cases (0.097%), persistent hyaloid artery in 54 cases (0.351%), obstruction of nasolacrimal duct in 7 cases (0.046%) and lacrimal gland prolapse in 1 cases (0.007%). Five different diseases (457 cases, 2. 968%) detected were acquired in nature, including neonatal conjunctivitis in 391 case (2.539%), vitreous hemorrhage in 6 cases (0.039%), retinal hemorrhage in 34 cases (0.221%), and neonatal dacryocystitis in 23 cases (0.149%). Of 27 premature babies with body weight lower than 1500 g, 3 had retinopathy of prematurity (ROP, 6 eyes involved). CONCLUSIONS: Early intervention is of great importance for the prevention and treatment of neonatal ocular diseases. The screening of newborn ocular diseases is not only feasible but also effective in the monitoring and control of the eye diseases in neonates.

[Flash visual evoked potentials on newborns and infants].

OBJECTIVE: To explore the feasibility of applying flash visual evoked potentials (FVEPs) for visual function test newborns and infants and bring out the consultable laboratory values of FVEPs. The technology of FVEP could be used as diagnostic tests for those who failed the screening and the infants who were cared for in the NICU. METHODS: 41 normal neonates (

[Simultaneous screening program for newborns hearing and ocular diseases].

OBJECTIVE: To explore the model and the feasibility of newborn hearing and ocular disease simultaneous screening program and to study the birth prevalence of newborn hearing loss and newborn ocular diseases. METHODS: The universal newborn hearing screening (UNHS) was performed using transient otoacoustic emission (TEOAE) in well baby nursery and by a two-stage TEOAE and auto auditory brainstem response (AABR) protocol in neonatal intensive care unit (NICU). The UNHS was simultaneous done with newborn ocular disease screening program. The examination technical method was following: the response to light, external inspection of the eyes and lids, pupil examination, red reflex examination, funduscope examination after pupil dilation for referral (for all newborn in NICU). The infants who were referred by two-stage hearing screening and/or had high-risk factors of hearing loss received following-up and routine audiological evaluation and personalized intervention from 6 months to 3 years of age. The cases had positive sign and (or) abnormal results of the ocular disease screening were referred for further examination by pediatric ophthalmologists. RESULTS: A total of 16 800 children born in Jinan Maternal and Child Hospital from October 1, 2002 to April 30, 2005. Of these infants, 15 398 cases (91.7%) had access to the simultaneous screening program for hearing and ocular diseases. The incidence of congenital sensorineural hearing loss (SNHL) among infants who did UNHS was 0.312% (48/15 398) in bilateral and 0.227% (35/15 398) in unilateral; Of the 4 cases of congenital SNHL complicated with newborn ocular diseases: 1 profound SNHL (bilateral), auditory neuropathy with congenital cataract (bilateral), 1 mild SNHL (bilateral) with membrana papillaris perseverance (left) and 1 mild SNHL (bilateral) with retina vein dilatation (bilateral), 1 mild SNHL (right) with persistent hyaloid artery (bilateral). In all 15 398 newborns, 15 neonates with congenital cataract were detected (22 eyes, 0.10%). Twenty seven neonates with less than 1500 g birth weight admitted to NICU, retinopathy of prematurity was detected in 3 neonates (6 eyes). CONCLUSION: Hearing loss and ocular diseases was not rare in neonatal and infancy. Newborn hearing and ocular disease simultaneous screening program was not only feasible but also effective in detecting hearing loss and (or) ocular disorders. Early intervention was important for the prevention or treatment of neonatal hearing loss and (or) ocular diseases, such as newborn hearing loss with congenital cataract, retinopathy of prematurity and so on.
