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.

Objective To explore the chest features of patients with the novel influenza type A H1N1 on HRCT. Methods One hundred and seventy-two chest HRCT examinations on 163 cases with Influenza type A H1N1 (9 cases were reexamed) were retrospectively analyzed using standard pulmonary window and mediastinal window, respectively. HRCT imaging appearances were summarized. Results Ninety-seven cases showed normal on chest HRCT, while the others showed abnormalities of parenchymal and interstitial. Among them, HRCT identified ground-glass opacity in 35 cases (53.0%), centrilobular nodules in 30 cases (45.5%), thickening of intralobular septa in 31 cases (47.0%), intralobular thin reticulation and micro-nodule in 8 cases (12.1%), single-lobular inflammation in 19 cases (28.8%), consolidation of lung(the large consolidation and multiple small consolidations)in 15 cases (22.7%), pulmonary atelectasis in 3 cases (4.5%), and irregular lines in 2 cases (3.0%). Pleurisy was also revealed including 8 cases with right pleurisy, 5 cases with left pleurisy, and 19 cases with bilateral pleurisy. Mediastinal and axillary lymphadenopathy were found in 7 cases, who were spared of pleural effusion. All above abnormalities resolved quickly after anti- virus treatment. Conclusion Parenchymal and interstitial abnormalities, mediastinum and axillary fossa lymphadenopathy, and pleural effusion were the common findings on HRCT in patients with Influenza type A H1N1, which were similar to those of other viral pneumonia.

ObjectiveTo study the appearances and dynamic changes of chest high resolution computed tomography (HRCT) in clinically diagnosed critical influenza A (H1N1) pneumonia.MethodsOne hundred chest HRCT scanning examinations were performed in 36 cases of influenza A (H1N1) pneumonia who were diagnosed by the clinical manifestations in one month.The onset,progress and resolve of pulmonary manifestations were analyzed.Results Chest HRCT was performed in six patients,and small patchy opacity presented in three cases and ground-glass opacities presented in the other three cases within 3 days after onset when the disease was at the initial stage.Multiple larger opacities were visualized in all cases at the progressive stage (3 days later after onset),which included the pure ground-glass opacities (9 cases,25.0％ ),ground-glass opacities accompanied by consolidations (20 cases,55.6％),prominent consolidations (7 cases,19.4％),and accompanied pleural lesions (10,27.8％).The lesions strongly progressed within (8.0± 2.6) d and distinctly absorption in all cases (100.0％,36/36) within (16.0±4.8) d after onset of the disease.The pulmonary interstitial hyperplasia was found in 23 cases (63.9％).Dynamic change types of the lesions include absorption after progression,absorption and progression coexistence then absorption and gradually absorption,andabsorptionafterprogressionwas themajor type(41.7％).ConclusionHRCT could distinctly demonstrate the shape,range and dynamic changes of pulmonary lesions of critical influenza A (H1 N1) pneumonia.

Two cases of incomplete regression of ventral mesogastrium were reported. Their nomenclature, etiology, symptoms and characteristic roentgenologic findings were discussed in relation to anatomical study. Because of its unique etiology and symptoms, charecteristic roentgenologic findings, and effectual remedy, it is suggested that this disease should be distinguished from "abnormal adhesion of fibrous bands" as an independent anomaly called incomplete regression of ventral mesogastrium. The roentgenological findings were: An incisure was found in the upper portion of pars descendens duodeni. It sank deeply and reduced two thirds of the normal diameter of the intestinal lumen to form an eccentrie intestinal stenosis. The intestinal lumen, near the inner border of the incisure was smooth, and there was no sign of serrated image formed by intestinal mucosa. The part of intestinal lumen was not distended in hypotonic radiography. All the above signs were caused by the traction and binding of the nonregressed mesogastrium.

Objective To screen a sensitive method for detecting respiratory viruses from three different methods of singleplex conventional PCR , multiplex conventional PCR and multiplex real-time RT-PCR.Methods Parallel examination of 17 respiratory viruses was performed on 73 throat swab specimens collected from patients with upper respiratory tract infection by the three methods .The detection rates of dif-ferent respiratory viruses were used as evaluating indicator for the three methods .Results The numbers of respiratory viruses detected by singleplex conventional PCR , multiplex conventional PCR and multiplex real-time PCR were 56, 41 and 87, respectively.Conclusion The multiplex real-time RT-PCR might be used for the detection of respiratory viruses in laboratory as its high detection rate in comparison with the other two methods .

Objective To investigate the characteristics and risk factors for cognitive decline in elderly patients with cerebral infarction.Methods A cross-sectional study was performed to investigate the population of Jiang'an Town,Rugao,Jiangsu Province from November 13,2014 to December 21,2014.The samples from the Rugao longitudinal study of aging included 1 788 individuals from 31 villages aged from 70 to 84 years.They were all Han nationality,including 830 males and 958 females.History of cerebral infarction was identified according to the neurological diagnosis confirmed by the secondary hospital and above or brain CT.The modified Kyohko Hasegawa dementia scale was used to evaluate the cognitive function.Five dimensions (orientation,memory,near memory,computing power,and common sense) of this population were assessed.The total score >21.5 was non-cognitive impairment and ≤21.5 was cognitive impairment.Multivariate logistic regression was used to analyze the risk factors for cognitive decline in elderly patients with cerebral infarction.Results (1) In the 1 788 subjects,133 had cerebral infarction (7.4%),and 1 655 did not have cerebral infarction.The proportion of hypertension in patients with cerebral infarction was higher than that without cerebral infarction (63.9% [n=85] vs.41.7% [n=690]).The high-density lipoprotein cholesterol level was lower than that of the non-cerebral infarction group (1.40±0.29 mmol/L vs.1.47±0.33 mmol/L).There was statistically significant difference (all P<0.05).(2) The patients with cerebral infarction were partially impaired in orientation and computational power,and the overall cognitive function score was 20±7,which was significantly lower than patients with non-cerebral infarction (21±6).The difference between the two groups was statistically significant (P<0.05).(3) In 133 patients with cerebral infarction,76 had cognitive impairment,the incidence was 57.1%,and 59 of them were women.The average value of serum creatinine in patients with cognitive impairment was 59±15 μmol/L,which was significantly lower than those with non-cognitive impairment (66±14 μmol/L).There was significant difference (P<0.05).(4) Multivariate logistic regression analysis showed that the education level below primary school (OR,2.86,95%CI 2.19-3.72) and female (OR,1.85,95%CI 1.50-2.28) were the independent risk factors for cognitive decline in elderly patients with cerebral infarction.High serum creatinine concentration (OR,0.96,95%CI 0.95-0.97) was a protective factor for it.Conclusion The cognitive function of the elderly was decreased after cerebral infarction,especially in the aspect of orientation and calculation.The education level below primary school and women were the independent risk factors for cognitive impairment,and high serum creatinine concentration had a certain protective effect.

Sulfonamides (SAs), such as sulfaguanidine (SGD), sulfadiazine (SDZ), sulfathiazole (STZ) and sulfamethazine (SMZ), can drastically inhibit the chemiluminescence (CL) intensities generated in both Ag-Luminol and Ni-Luminol systems.Based on these observations, a novel method of high performance liquid chromatography (HPLC) coupled with CL detection was established.Both the Ag-Luminol and Ni-Luminol CL systems were employed as detectors, and the performances of the two detecting systems were compared.After separated by HPLC, four SAs reacted with Ag-Luminol and Ni-Luminol CL system, respectively.Chromatographic conditions were as follows: reversed-phase C18 column (250 mm × 4.6 mm,5 μm), gradient elution, and 0.1% (V/V) formic acid-methanol as mobile phase with flow rate of 1 mL/min.CL conditions were as follows: [Ag]=1.4×10.-4 mol/L (in 0.12 mol/L NaOH);[Ni]=1.5×10.-5 mol/L (in 0.12 mol/L NaOH);[Luminol]=1.2×10.-7 mol/L;and flow rate=1.0 mL/min.Under the optimal conditions, the detection limits of Ag-Luminol CL system were 0.15, 0.96, 1.10, 1.50 μg/mL for SGD, SDZ, STZ, and SMZ, respectively, and the recovery were 81.0%-101.5%.Comparatively, the detection limits of Ni-Luminol CL system were 1.5, 17.2, 16.8 μg/mL for SGD, SDZ and STZ, and the recoveries was 83.9%-110.8%.The result showed that the Ag-Luminol CL system had a much better performance.The method was applied to the determination of the residues of the above four SAs in milk with satisfactory results.

Objective To investigate the genetic characteristic of whole-genome of influenza A/H3N2 viruses in severe acute respiratory infection cases in Beijing area.Methods From 2014 to 2016,the viral RNA was extracted from 32 strains isolated from SARI cases,then sequenced by Ion Torrent PGM Sequencer.The phylogeny and molecular features of whole-genome were analyzed by Mega and Consurf software.Results The HA gene of tested strains isolated in 2014-2015 influenza season belonged to lineage 3C.3a and 3C.2a,while those isolated in 2015-2016 influenza season belonged to cluster 3C.2a.Moreover,compared with the vaccine strains,7 variant amino acids of protein of HA1 were identified,and two of them were located in antigenic sites.All isolates were sensitive to neuraminidase inhibitors while showed resistance to blockers for M2 ion channel.Conclusion The phylogenetic features of isolates studied in this study are similar with that of current circulating strains.However,the difference between isolates and vaccines should not be overlooked.

Objective To evaluate the correlation of epicardial adipose tissue volume (EATV)with coronary plaques in patients with a coronary artery calcium score of zero.Methods 183 patients with a coronary artery calcium score of zero were selected.They were divided into plaque group and control group according to the findings of CT coronary angiography.Independent t test was used to analyze the difference of EATV between two groups.Results ①EATV was significant higher in plaque group than that in control group (P <0.05).②EATV was non-significant higher in plaque group than that in control group for female individuals (P >0.05), while it was significant higher in plaque group than that in control group for male individuals (P <0.05).③EATV was significant higher in plaque group than that in control group for the individuals with age< 50 years (P <0.05 ),meanwhile it was significant higher in plaque group than that in control group in age≥50 years(P <0.05).Conclusion EATV is correlated with coronary plaques in male patients with a coronary artery calcium score of zero while there is no correlation with female patients.EATV is correlated with coronary plaques in different age patients with a coronary artery calcium score of zero.

Objective To investigate the effect of ultrasound guided block of pericapsular nerve(PENG)combined with lateral femoral cutaneous nerve(LFCN)on analgesia,stress response and postoperative cognitive function in patients undergoing hip replacement.Methods 102 patients who underwent hip Joint replacement in our hospital from September 2020 to September 2022 were selected and randomly divided into control group(51 cases)and study group(51 cases).The control group was given ultrasound guided iliac fascia space block(FICB),and the study group was given ultrasound guided PENG combined with LFCN block.The perioperative related indicators,postoperative analgesia effect,stress response indicators and postoperative cognitive function of the two groups were compared.Results There was no statistically significant difference in the comparison of surgical time between the two groups(P＞0.05).The amount of sufentanil used and the number of analgesic pump used within 48 hours after surgery in the study group were significantly lower than those in the control group(P＜0.05).The first postoperative time of getting out of bed and hospitalization in the study group were significantly shorter than those in the control group(P＜0.05).There was no statistically significant difference in VAS scores between the two groups at 6 h,12 h,24 h,and 48 h after surgery(P＞0.05).The VAS scores of the study group were significantly lower than those of the control group at 6 h,12 h,and 24 h after surgery(P＜0.05).The heart rate(HR)and Mean arterial pressure(MAP)of the control group were higher at the time of block(T1),30 min of block(T1)(T2),and the end of block(T3)than at the time of entry(T0)(P＜0.05).HR and MAP of the study group were significantly lower than those of the control group(P＜0.05).The MMSE scores of the two groups at 6 h,12 h,24 h,and 48 h after surgery were lower than those before surgery(P＜0.05),but the MMSE scores of the study group were significantly higher than those of the control group(P＜0.05).Conclusion Using ultrasound guided PENG combined with LFCN block for patients undergoing hip Joint replacement can more effectively reduce the amount of opioids and the number of use of analgesia pump,reduce postoperative pain in the exercise state,reduce stress reaction,and have less impact on cognitive function,so as to promote faster recovery of patients.
