Blood glucose control is not only the key issue of diabetes management, but also one of the goals of diabetes treatment.Pain associated with self-monitoring of blood glucose(SMBG)results in poor compliance with blood glucose testing.With the advent of continuous glucose monitoring(CGM), it is more convenient to detect blood glucose and realize dynamic glucose monitoring.Continuous glucose monitoring(CGM)is widely used in adults with diabetes, and the usage among children is also increasing.Many studies have conducted clinical trials on the use of CGM in children with diabetes, initially confirming the use of CGM in children with diabetes.However, some studies still have controversies on the use of CGM in children.In this paper, the clinical studies of CGM in children′s diabetes in recent years were summarized to further understand the application of CGM and its combined insulin pump in pediatrics.

The study aims to develop an LC-MS/MS method for the simultaneous determination of amygdalin and paeoniflorin in urine samples, and to investigate their urinary excretion characteristics in healthy volunteers after intravenous infusion administration of Huoxue-Tongluo lyophilized powder for injection (HTLPI). The urine samples were extracted by methanol, and then separated on a Hedera ODS-2 column with a mobile phase of acetonitrile and 5 mmol · L(-1) ammonium acetate buffer solution containing 0.05% formic acid (20:80). Electrospray ionization source was applied and operated in the positive ion mode using MRM. The method exhibited good linearity over the concentration range of 0.03 -40 µg · mL(-1). The values on both the occasions (intra- and inter-day) were all within 15% at three concentration levels. No matrix effect and carry-over effect were observed. Amygdalin and paeoniflorin were stable in human urine under different storage conditions. Approximately 79.6% of the administered amount of amygdalin was excreted unchanged in urine within 24 h and which was 48.4% for paeoniflorin. The developed LC-MS/MS method can be applied to evaluate the urinary excretion of amygdalin and paeoniflorin.

Objective To investigate the relationship between pancreatic cancer and diabetes mellitus (DM). Methods Two hundreds and twenty patients with pancreatic cancer and 300 controls, who suffered from non-digestive tract, non-neoplastic or non-hormone-related disorders, were enrolled from 1997 to 2007. The incidence of diabetes between the two groups and the relationship between pancreatic cancer and diabetes were compared, pancreatic cancer patients with DM were compared with patients without DM for their gender, age, location and differentiate degree of the cancer. Results The incidence of DM in the two groups were 33.1% and 9.67%, respectively, and the difference was significant (P < 0.05). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2 years or for more than 10 years were 25.91% (57/73) and 3.18% (7/73), which were significant higher than those in the control group 6.0% (18/29) and 0.67% (2/29)) (χ2=46.15, P<0.01, 0R=6.07; χ2 =4.72, P<0.01, OR=4.90). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2～5 years or 5～10 years was not significant different when compared with that of the control group, and there was no significant difference in terms of gender, age and cancer location between the pancreatic cancer patients with DM and without DM. The majority of pancreatic cancer patients with DM had corpora mammillaria or well differentiated adenocarcinoma, and the majority of pancreatic cancer patients without DM had differentiated adenocarcinoma. Conclusions DM was closely related with pancreatic cancer and DM may be one of the presentations of pancreatic cancer, as well as a possible risk factor for the tumor.

Objective To evaluate the diagnostic value of cerebrospinal lactate for the diagnosis of bacterial meningitis in patients post-neurosurgical operation (PNBM) with blood-contaminated cerebrospinal fluid (CSF). Methods A prospective observational study was conducted. 101 patients underwent neurosurgical operation and clinically suspected PNBM admitted to neurosurgical intensive care unit (NSICU) of the First Affiliated Hospital of Sun Yat-sen University from October 2015 to December 2016 were enrolled. Based on red blood cell quantitative test in CSF, the patients were divided into blood-contaminated and non blood-contaminated CSF groups. According to the PNBM diagnostic criteria of 2008 Centers for Disease Control and Prevention/National Healthcare Safety Network (CDC/NHSN), all patients were divided into PNBM group and non-PNBM group. The biochemical indexes levels in CSF were compared among the groups. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic power of CSF lactate for PNBM in blood-contaminated patients.Results A total of 101 suspected PNBM patients were enrolled. In 77 blood-contaminated CSF patients, 39 patients were diagnosed as PNBM (account for 50.6%); in 24 non-blood-contaminated patients, 12 patients were diagnosed as PNBM (account for 50.0%). ① In non-PNBM patients, the lactate level in blood-contaminated CSF was significantly higher than that of non-blood-contaminated CSF (mmol/L: 3.5±1.3 vs. 2.3±1.1,P < 0.01). In PNBM patients, there was no significant difference in lactate level between blood-contaminated CSF and non blood-contaminated CSF (mmol/L: 6.8±2.1 vs. 6.9±2.5,P > 0.05). ② In both blood-contaminated and non blood-contaminated CSF, white blood cell (WBC), protein and lactate levels in PNBM group were significantly higher than those in non-PNBM group [WBC (×106/L): 660.0 (67.5, 1105.0) vs. 41.0 (15.0, 142.5) in blood-contaminated CSF,168.0 (86.5, 269.5) vs. 34.5 (7.0, 83.5) in non-blood-contaminated CSF; protein (mg/L): 4757.8 (2995.2, 10219.8) vs. 1292.8 (924.2, 1936.2) in blood-contaminated CSF, 39247.3 (14900.6, 62552.2) vs. 1441.6 (977.3, 2963.9) in non blood-contaminated CSF; lactate (mmol/L): 6.8±2.1 vs. 3.5±1.3 in blood-contaminated CSF, 6.9±2.5 vs. 2.3±1.1 in non blood-contaminated CSF, allP < 0.05], and glucose and CSF glucose/blood glucose ratio in PNBM group were significantly lower than those in non-PNBM group [glucose (mmol/L): 2.5±1.2 vs. 4.4±1.6 in blood-contaminated CSF, 1.9±1.4 vs. 3.4±0.9 in non blood-contaminated CSF; CSF glucose/blood glucose ratio: 0.28±0.15 vs. 0.46±0.16 in blood-contaminated CSF, 0.24±0.16 vs. 0.45±0.11 in non blood-contaminated CSF, allP < 0.01]. ③ It was shown by ROC curve analysis that CSF lactate level was a good diagnostic parameter for PNBM both in blood-contaminated and non blood-contaminated CSF, and the area under ROC curve (AUC) was 0.91 and 0.97, respectively. When the cutoff value of lactate in non blood-contaminated CSF was 3.35 mmol/L, the sensitivity was 100%, and the specificity was 91.7%. When the cutoff value of lactate in blood-contaminated CSF was 4.15 mmol/L, the sensitivity was 92.3%, and the specificity was 71.1%, and the combination of CSF lactate and glucose achieved better diagnostic specificity (AUC = 0.96, sensitivity was 97.4%, specificity was 84.2%).Conclusions Blood in CSF led to the elevation of CSF lactate as compared with that in non-blood-contaminated CSF of patients with PNBM. CSF lactate was still a good diagnostic parameter for PNBM both in blood-contaminated patients, and the combination of CSF lactate and glucose achieved better diagnostic specificity.

Objective To explore the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and metabolic syndrome (MS) in obese middle-aged and older men. Methods We selectively recruited 154 obese middle-aged and older men matched for body mass index (BMI) and age. The polysomnography was performed for diagnosing OSAHS and for discriminating disease severity. The BMI, waist circumference, blood pressure, plasma glucose and lipid profiles were measured and analyzed in all subjects. Appropriate statistical methods were used to compare the components of MS in each group. Logistic regression was taken to elucidate the relationship between OSAHS and MS. Results Compared to control group, severe OSAHS group had significantly lower high density lipoprotein cholesterol level [( 1.03 ± 0.29 ) mmol/L vs. ( 1.31 ± 0. 38) mmol/L,P＜0. 05] and higher fasting glucose [(6.61±1.76) mmol/L vs. (5.47±0.64) mmol/L, P＜0. 05]as well as higher systolic blood pressure [( 133 ± 13) mm Hg vs. ( 125 ± 12) mm Hg, P＜0. 05] and diastolic blood pressure [(99±10) mm Hg vs. (80±5) mm Hg, P＜0. 05]. The prevalence of MS was significantly higher in OSAHS group than in control group (mild OSAHS group: 25.7%,moderate OSAHS group: 46. 5%, severe OSAHS group: 84.4%, control group: 16. 1 %, all P＜0. 01). OSAHS was independently associated with an increased prevalence of MS Odds ratio, 6.16).Conclusions OSAHS is independently associated with MS in obese middle-aged and older men.

Objective To observe the expression level change of vascular endothelial growth factor (VEGF) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the relationships of VEGF expression with OSAHS, OSAHS related cardiovascular and cerebrovascular diseases. Methods Polysomnography (PSG) was used to conduct sleep apnea monitoring in 24 OSAHS patients from 6OSAHS popular families and 48 healthy controls with normal physical examination results. The expression of VEGF mRNA was examined by reverse transcriptionpolymerase chain reaction (RT-PCR) analysis, meanwhile, the level of VEGF in plasma was measured VEGF mRNA in PBMC were significantly higher in simple OSAHS group [plasma levels: (205.75±2.79) pg/ml; mRNA: 0. 61±0. 02] than in control group [(168.72±4.64) pg/ml; 0. 47±0. 02,cardiovascular and cerebrovascular diseases group [(288.74 ± 2.73) pg/ml, 1.16 ± 0. 03] than in simple OSAHS group [ ( 205.75 ± 2.79 ) pg/ml, 0. 61 ± 0.02, P ＜ 0. 01]. ( 2 ) There was a positive correlation of the levels of VEGF in plasma and mRNA with AHI as well as systolic and diastolic blood pressure in early morning. There was a negative correlation of the level of VEGF in plasma and VEGF mRNA with the lowest saturation of blood oxygen. There was a positive correlation of the level of VEGF mRNA with AHI as well as systolic and diastolic blood pressure in early morning.Conclusions The level of VEGF in OSAHS significantly increases, which may play a role in the pathophysiology of OSAHS and OSAHS related cardiovascular and cerebrovascular diseases.

Objective: This study aimed to detect the expression levels of the key proteins involved in the insulin-like growth factor signaling pathway of patients with ovarian cancer. These proteins include insulin-like growth factor-1 (IGF1), insulin-like growth factor-1 receptor (IGF1R), and protein kinase B (AKT). Methods: Ovarian cancer tissues were subjected to drug resistance tests using the ATP-TCA method. IGF1, IGF1R, AKT, and multidrug resistance protein2 (MRP2) expressions were detected in the sera of patients with ovarian cancer by conducting enzyme-linked immunosorbent assay. IGF1, IGF1R, and AKT protein expressions were detected in the surgical specimens by immunohistochemistry. Patients were instructed to monitor their cancer antigen 125 (CA125) levels monthly from the date a patient was discharged to the last day of chemotherapy (or until chemotherapy was completed). A color Doppler ultrasound, CT, or MRI scan was required if CA125 value is abnormal. The total follow-up time was one year. Results: IGF1, IGF1R, and AKT expressions were significantly higher in the cisplatin-resistant group than in the cisplatin-sensitive group (P =0.000 1). Immunohistochemical results showed that IGF1, IGF1R, and AKT expressions were significantly higher in the cisplatin-resistant group than in the cisplatin-sensitive group (P<0.05). The monthly CA125 values of 40 patients were obtained after chemotherapy. In the cisplatin-sensitive group, 18 of the 24 cases exhibited normal CA125 values for more than one year, and the remaining 6 cases maintained normal values for more than half a year. In the cisplatin-resistant group, 16 cases revealed higher than normal CA125 values for half a year after chemotherapy. Recurrent lesions were observed in their color Doppler ultrasound results or MRI scans. Conclusion: Cisplatin resistance in ovarian cancer is strongly correlated with the expressions of IGF1, IGF1R and AKT. IGF1 is a potential candidate for the targeted therapy of ovarian cancer.
