OBJECTIVE: To explore the genetic etiology of two patients with Perrault syndrome (PRLTS) in a family. METHODS: Whole exome sequencing (WES) was carried out to screen potential variants within genomic DNA extracted from the proband. Suspected variants were validated by clinical data and results of Sanger sequencing. RESULTS: WES has identified two heterozygous variants of TWNK gene, namely c.1172G>A (p.Arg391His) and c.1844G>C (p.Gly615Ala). Sanger sequencing confirmed that the c.1172G>A (p.Arg391His), a known pathogenic variant, was derived from her father, while the c.1844G>C (p.Gly615Ala), a novel variant, was derived from her mother. Her brother, who was similarly affected, has carried the same compound heterozygous variants. CONCLUSION The compound heterozygous variants c.1172G>A (p.Arg391His) and c.1844G>C (p.Gly615Ala) of the TWNK gene probably underlie PRLTS in the sib pair. The above results have facilitated genetic counseling and prenatal diagnosis for the affected family.

Objective To investigate the diagnostic value of 3.0T MR high field high-b-value diffusion weighted imaging (DWI) in prostate cancer (PCa) and to analyze its correlation with Gleason classification.Methods A total of 78 cases proved by operation and pathology were collected,including 41 cases of benign prostatic hyperplasia(BPH) and 37 cases of PCa.PCa patients were classified according to postoperative pathological scores,and their correlation with ADC values was analyzed subsequently.Parameter scanning was performed in all patients by using Philps 3.0T MR with b value at 0 s/mm2,1 000 s/mm2 and 1 500 s/mm2.The signal intensity and ADC value of PCa and BPH were compared under two kinds of high-b-values,and the correlation between ADC value and Gleason classification was analyzed.Results It was found that the specificity and accuracy of T2WI combined with b value of 1 500 s/mm2 were higher than these of T2WI combined with b value of 1 000 s/mm2 for the diagnosis of PCa.The ranking result of ADC value corresponding to Gleason score of PCa after operation was:2-4 points ＞ 5-6 points ＞7 points ＞ 8-10 points.Besides,the ADC value of the corresponding lesion with b value of 1 500 s/mm2 was lower than that with b value of 1 000 s/mm2,and the difference was statistically significant (P＜0.05).Conclusion High field high-b-value DWI combined with T2WI is of high value in differential diagnosis of PCa and BPH,and the specificity and accuracy of PCa and BPH improve obviously with the increase of the b value.Additionally,the ADC value is negatively correlated with the Gleason score.

OBJECTIVETo evaluate the feasibility, safety and short-term clinical outcomes of robot-assisted minimally invasive esophagectomy (RAMIE).

METHODSClinical data of 17 patients with esophageal cancer who received RAMIE between April 2016 and July 2016 were analyzed retrospectively.

RESULTSThe age of the patients ranged from 44 to 83. Six patients received neoadjuvant radiochemotherapy while 11 patients underwent surgery alone. All patients were performed by the robot-assisted thoraco-laparoscopic minimally invasive esophagectomy. In-hospital mortality was 0%. None was converted to open transthoracic or laparotomy approach. In the neoadjuvant radiochemotherapy group, 3 patients received pathological complete response while 2 patients were stage II(A and 1 patient was stage II(B. In the surgery alone group, 1 patient was stage I(A, 3 patients were stage II(A, 5 patients were stage II(B, 1 patient was stage III(A and 1 patient was stage III(B. The mean operation time was 195 minutes (range 145 to 305 minutes). The mean blood loss was 60 ml (range 30 to 200 ml). Mean lymph node harvest was 28 nodes. The rate of radical resection was 100%. Median ICU stay was 4.5 days (range 1 to 36 days), and median overall postoperative hospital stay was 15.2 days(range 9 to 45 days). Postoperative complication occurred in 4 (23.5%) patients, including 3 (17.6%) of lung lesion, 2 (11.8%) of hoarseness, 1 (5.9%) of chylothorax, while no anastomotic leakage and arrhythmia was observed.

CONCLUSIONRAMIE for esophageal cancer is feasible and safe with favorable early outcomes.

Objective:To design a modified S1PR3 specific agonist, GPS-725.017, and investigate its protective effect on acute lung injury by promoting macrophage clearance of bacteria.Methods:A short peptide derived from the intracellular region of S1PR3 receptor was named GPS725.017, which was modified with norleucine (Nle) and myristicacid (myr) at its N terminus. Mice were divided into the sham operation group, solvent group and GPS-725.017 treatment group. The acute lung injury model was induced by endotracheal injection of E. coli (5×10 6 CFU), and the experimental group was treated with GPS-725.017 (10 mg/kg). The 48-h survival rate of mice was recorded. After 5 h of modeling, the bacterial load and inflammatory cytokines in peripheral blood and lung were detected, and Vps34 protein content in alveolar macrophages was determined by Western blot. After 12-h of modeling, lung tissues were collected for H&E staining and pathological scores. Results:Compared with the solvent group, the survival rate of mice in the GPS-725.017 treatment group was significantly improved ( P<0.01), the bacterial CFU in blood and alveolar lavage fluid was significantly lower than that in the solvent group ( P<0.001), and the levels of TNF-α and IL-1β in blood and alveolar lavage fluid were significantly lower than those in the solvent group ( P<0.001). Western blot showed that the expression level of Vps34 protein in alveolar macrophages was significantly higher than that in the solvent group ( P<0.01). Histopathology result showed that the pathological damage of lung in the treatment group was significantly less than that in the solvent group ( P<0.001). Conclusions:The modified synthetic S1PR3 specific agonist GPS-725.017 could specifically activate the S1PR3 receptor on the membrane of alveolar macrophages and up-regulate the expression level of intracellular Vps34 protein, which can promote the removal of bacteria in alveolar macrophages, significantly reduce the degree of lung injury and improve the survival rate in ALI mice.

Background In recent years, the incidence of metabolic syndrome (MS) is increasing significantly in China. Some studies have found that temperature is related to single metabolic index, but there is a lack of research on associated mechanism and identifying path of the influence of temperature on MS. Objective Based on the data of Guangdong Province, to investigate the effect of temperature on MS and its pathway. Methods A total of 8524 residents were enrolled by multi-stage random sampling from October 2015 to January 2016 in Guangdong. Basic characteristics, behavioral characteristics, health status, and physical activity level were obtained through questionnaires and physical examinations, and meteorological data were obtained from meteorological monitoring sites. We matched individual data both with the temperature data of the physical examination day and of a lag of 14 d. A generalized additive model was used to explore the exposure-effect relationship between temperature and MS and its indexes, calculate effect values, and explore the effects of single-day lag temperature. Based on the literature and the results of generalized additive model analysis, a path analysis was conducted to explore the pathways of temperature influencing MS. Results The association between daily average temperature on the current day or lag 14 day and MS risk was not statistically significant. When daily average temperature increased by 1 ℃, the change values of fasting blood-glucose (FBG), systolic blood pressure (SBP), diastolic blood pressure (DBP), and high density lipoprotein cholesterol (HDL-C) were −0.033 (95%CI: −0.040-−0.026) mmol·L⁻¹, −0.662 (95%CI: −0.741-−0.583) mmHg, −0.277 (95%CI: −0.323-−0.230) mmHg, and −0.005 (95%CI: −0.007-−0.004) mmol·L⁻¹ respectively. The effects of average daily temperature on FBG, blood pressure, HDL-C, and waist circumference lasted until lag 14 day. The effects of daily average temperature on SBP and DBP were the largest on the current day. Daily average temperature of current day had direct and indirect effects on FBG and SBP. Temperature had an indirect effect on TG, and the intermediate variables were waist circumference and FBG, with an indirect effect value of −0.011 (95%CI: −0.020-−0.002). The indirect effects of daily average temperature on SBP, FBG, and TG were weak. Conclusion There is no significant correlation between temperature and risk of MS, and daily average temperature of current day could significantly affected blood pressure and FBG with a lag effect. Daily average temperature of current day has indirect effects on FBG and TG.
