Several genetic polymorphisms of the aldosterone synthase gene(CYP11B2),which may influence the plasma aldosterone levels,had been reported to influence the blood glucose levels.In addition to the effects of sodium()(and consequently water) resorption and potassium excretion(),aldosterone could be involved in the development and progression of diabetes and its chronic complications.This paper also discussed the therapeutic significance of aldosterone receptor antagonists on the occcurance of chronic diabetic complications.

Objective To investigate the change of 25-hydroxyl vitamin D level and its impact on glucose metabolism and bone mineral density in type 2 diabetic patients.MethodsTwo hundred and fifty-eight cases of type 2 diabetic patients in our hospital were collected.In accordance with 25 (OH) D =50 nmol/L for the critical values,they were grouped into vitamin D deficiency group ( n =192) and the relative lack of vitamin D group ( n =66).Dual-energy X-ray absorptiometry (DXA) measurement of the lumbar vertebrae L2 - L4 and femoral neck bone mineral density were undertaking.Taking the total value of the lumbar spine,femoral neck and total value as judgment indicators,homeostasis model assessment of insulin resistance (HOMA-IR),we collected and statistically analyzed glucose metabolism and bone metabolism indicators in patients with diabetes.Results Among 258 cases of type 2 diabetes,there were 57 cases of osteoporosis accounting for 22.1%.There was significant difference on the duration of diabetes [ (7.98 ± 1.09 ) years old vs (3.77 ± 1.21 ) years old,t =4.849,P <0.05],FINS [ (6.42 ± 1.30) mU/L vs (5.79 ± 1.08) mU/L,t =3.871,P <0.05] and HOMA-IR [ (2.35 ±0.54) vs ( 1.85 ±0.41 ),t =2.705,P <0.05],but no significant difference on the FPG and HbA1c ( P > 0.05 ) between two groups.PTH [ ( 36.51 ± 7.59) ng/L vs ( 32.02 ± 6.89 ) ng/L,t =2.008,P < 0.05 ],bone mineral density in the lumbar total value [ (0.87 ±0.14) g/cm2 vs (0.99 ±0.12) g/cm2,t =2.799,P <0.05 ],femoral neck Neck [ ( 0.70 ± 0.10 ) g/cm2 vs ( 0.79 ± 0.11 ) g/cm2,t =2.564,P < 0.05 ] and Total [ (0.84 ± 0.14) g/cm2 vs (0.97 ± 0.15 ) g/cm2,t =3.340 P < 0.05 ] were statistically different,but no significant difference on the rest of the indicators.Conclusion The prevalence of vitamin D deficiency was found in patients with diabetes.Vitamin D level could affect insulin resistance and glycemic control and bone mineral density level.Therefore,routine vitamin D testing to the diabetic patients and giving vitamin D replacement therapy to vitamin D deficiency patients in a timely manner were necessary.

Objective To analyze the efficacy of the combination of MALDI-TOF and immunoadsorption to detect new biomarkers for lupus. Methods Twenty lupus patients at active stage (SLE group), 10 SLE patients in remission (SLE control group), 10 RA patients and 10 PSS patients (other rheumatic disease control group) and 20 healthy volunteers (healthy control group) were enrolled. The serum samples before and after immunoadsorption from SLE group and those from the control groups were co-incubated with activated chitosan copper derivative nano material. The adsorbed nano material was spotted onto the matrix used in MALDI-TOF for analysis by the Axima-CFR plus MALDI-TOF mass spectrometer. T-test was used for statistical analysis. Results MALDI-TOF MS screening showed that three potential protein biomarkers of mass-to-charge (m/z) ratio 3136, 3264, 3326 were found to be very specific for lupus patients: All of them were expressed before immunoadsorption in high quantity and none of them could be detected both after immunoadsorption and in all the three control groups. None of them (<10 000) were in the molecular weight range of the biomarkers used nowadays such as auto antibodies and complement (>50 000). Conclusion The combination of MALDI-TOF and immunoadsorption is effective in the detection of new serum protein biomarkers for lupus and it may be helpful in the screening of SLE patients at active stage from healthy people.

Objective:To explore the clinical effect of different flow rates of transnasal humidified rapid-insufflation ventilatory exchange (Thrive) on hypoxic events during painless gastroscopy.Methods:Patients who underwent painless gastroscopy in Nanjing First Hospital from April to July 2020 were randomly selected by random number table method and assigned to Thrive groups of 30 L/min ( n=52), 50 L/min ( n=55) and 70 L/min ( n=54). The incidences of different degree of hypoxic events (including subclinical respiratory depression, hypoxia and severe hypoxia) and adverse events related to Thrive were recorded. Results:The total incidence of hypoxic events in the 70 L/min group was 0 (0/54), which was significantly lower than that in the 30 L/min group (21.3%, 11/52, χ2=12.75, P<0.001) and 50 L/min group (12.7%, 7/55, P=0.007). There were no significant differences in subclinical respiratory depression [13.5% (7/52) VS 5.5% (3/55), χ2=1.19, P=0.194] or hypoxia [7.7% (4/52) VS 7.3% (4/55), P=0.610] between 30 L/min group and 50 L/min group. No severe hypoxia occurred in any group. The oxygenation of patients with hypoxemia in 30 L/min and 50 L/min groups was improved (SpO 2>95%) after opening the airway by mandibular support. In addition, there were no significant differences in the incidence of adverse events except hypoxemia among the three groups ( P>0.05). Conclusion:The flow rates of Thrive of 30 L/min, 50 L/min, and 70 L/min can prevent the occurrence of severe hypoxia during painless gastroscopy, and the flow rate of 70 L/min can further reduce the incidence of subclinical respiratory depression.

SAM pointed domain containing E26 transformation-specific transcription factor (SPDEF) plays dual roles in the initiation and development of human malignancies. However, the biological role of SPDEF in head and neck squamous cell carcinoma (HNSCC) remains unclear. In this study, the expression level of SPDEF and its correlation with the clinical parameters of patients with HNSCC were determined using TCGA-HNSC, GSE65858, and our own clinical cohorts. CCK8, colony formation, cell cycle analysis, and a xenograft tumor growth model were used to determine the molecular functions of SPDEF in HNSCC. ChIP-qPCR, dual luciferase reporter assay, and rescue experiments were conducted to explore the potential molecular mechanism of SPDEF in HNSCC. Compared with normal epithelial tissues, SPDEF was significantly downregulated in HNSCC tissues. Patients with HNSCC with low SPDEF mRNA levels exhibited poor clinical outcomes. Restoring SPDEF inhibited HNSCC cell viability and colony formation and induced G0/G1 cell cycle arrest, while silencing SPDEF promoted cell proliferation in vitro. The xenograft tumor growth model showed that tumors with SPDEF overexpression had slower growth rates, smaller volumes, and lower weights. SPDEF could directly bind to the promoter region of NR4A1 and promoted its transcription, inducing the suppression of AKT, MAPK, and NF-κB signaling pathways. Moreover, silencing NR4A1 blocked the suppressive effect of SPDEF in HNSCC cells. Here, we demonstrate that SPDEF acts as a tumor suppressor by transcriptionally activating NR4A1 in HNSCC. Our findings provide novel insights into the molecular mechanism of SPDEF in tumorigenesis and a novel potential therapeutic target for HNSCC.

Objective:
To analyze the feasibility and safety of enhanced recovery after surgery (ERAS) in colorectal surgery in municipal hospitals.
Methods:
The clinical data of patients with colorectal cancer in Zhangzhou Affiliated Hospital of Fujian Medical University from June 2016 to December 2018 were retrospectively analyzed. A total of 50 patients who underwent laparoscopic surgery combined with ERAS in the perioperative period were selected as the ERAS group, and 50 patients who underwent laparoscopic surgery combined with conventional methods in the perioperative period were treated as the control group. The general data were compared in the two groups, including age, gender, body mass index and the tumor site. The postoperative recovery was compared including fart time, defecation time, total fluid food intake time, nutritional indexes, postoperative leaving hospital time. And the postoperative complications were also compared, including wound infection, lung infection, anastomotic fistula, abdominal infection as well as the urinary infection.
Results:
The first fart time and total fluid food intake time in the ERAS group were earlier than those in the control group [(1.5±0.5) d vs. (2.1±0.8) d, (2.2± 0.8) d vs. (3.4±1.6) d], and the differences were statistically significant (
