ABSTRACT
Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.
ABSTRACT
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder. A 44-year-old man visited second Xiangya Hospital, Central South University due to hypoglycemia. He was eventually diagnosed as MEN1. A novel homozygous frameshift for c.640-643delCAGA (p.V215Mfs*13) of MEN1 gene was identified in the patient. After MDT (Multiple Disciplinary Team), open bilateral exploration with total parathyroidectomy and autotransplantation as well as partial pancreatectomy excision of all the macroscopic pancreatic tumors were performed at the same time. The patient recovered well. Individualized diagnosis and treatment are important for MEN1 patients.

ABSTRACT
Surface molecularly imprinted polymers (SMIPs) for selective adsorption of ampicillin sodium were synthesized using surface molecular imprinting technique with silica gel as a support. The physical and morphological characteristics of the polymers were investigated by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), elemental analysis and nitrogen adsorption–desorption test. The obtained results showed that the SMIPs displayed great adsorption capacity (13.5μg/mg), high recognition ability (the imprinted factor is 3.2) and good binding kinetics for ampicillin sodium. Finally, as solid phase extraction adsorbents, the SMIPs coupled with HPLC method were validated and applied for the enrichment, purification and determination of ampicillin sodium in real milk and blood samples. The averages of spiked accuracy ranged from 92.1%to 107.6%. The relative standard deviations of intra-and inter-day precisions were less than 4.6%. This study provides a new and promising method for enriching, extracting and determining ampicillin sodium in complex biological samples.

ABSTRACT
ObjectiveTo explore the relationship between plasma A-FABP and obesity type and degree,glucose and lipid metabolism parameters and insulin sensitivity.MethodsPlasma adipocyte fatty acid binding protein (A-FABP) was detected by double antibody sandwich ELISA in fasting status in subjects with normal glucose regulation and normal weight (NW-NGR,n =44),overweight or obese subjects with normal glucose regulation (OB-NGR,n =36),newly-diagnosed type 2 diabetes mellitus (T2DM) and its subgroups of T2DM with normal weight ( NW-T2DM,n =89 ) and T2D)M with overweight or obesity (OB-T2DM,n =44).And glucose,lipids,insulin levels as well as anthropometrical parameters such as body mass index ( BMI ),fat content ( Fat％ ),waist circumference (WC) and waist hip ratio (WHR) were measured.Meanwhile insulin sensitivity was assessed by HOMA-IR.ResultsAfter age and sex adjustment,plasma A-FABP levels in OB-NGR,NW-T2DM,and OB-T2DM were significantly higher than that of NW-NGR [11.32(6.54 - 15.43)μg/L,14.60(10.35 -20.10) μg/L,18.25(12.85 -26.65) μg/L vs 9.32(3.72 - 14.00) μg/L,all P ＜0.05].There was no difference in plasma A-FABP levels between OB-NGR and NW-T2DM [ 11.32 (6.54 - 15.43 ) vs 14.60 ( 10.35 -20.10) μg/L,P ＞ 0.05 ],but the plasma A-FABP levels in OB-NGR and NW-T2DM were significantly lower than that of OB-T2DM [ 11.32(6.54 - 15.43) μg/L,14.60( 10.35 -20.10) μg/L vs 18.25( 12.85 -26.65 ) μg/L,P ＜0.01 ].In a multiple stepwise regression analysis,HOMA-IR,sex,WC and age were the most significant independent determinants for plasma A-FABP concentration (all P ＜ 0.05 ).Conclusions Plasma A-FABP is strongly associated with the abdominal obesity and insulin resistance,measurement of plasma A-FABP concentrations might be useful for diagnosis of abdominal obesity and type 2 diabetics.
ABSTRACT
OBJECTIVE@#To determine the correlation of serum soluble CD14 (sCD14) level with the injury of vascular endothelial cells and chronic low grade inflammation in newly diagnosed Type 2 diabetes (T2DM).@*METHODS@#ELISA was used to examine serum sCD14 and serum soluble E-selectin (sE-selectin) level, while immunoturbidimetric assay was used to detect serum high sensitivity C reactive protein (hsCRP).@*RESULTS@#The levels of serum sCD14, sE-selectin, and hsCRP in newly diagnosed T2DM group were higher than those in the euglycemic group [sCD14: (300.7+/-136.6) ng/mL vs. (273.3+/-86.0) ng/mL); sE-selectin: (21.3+/-7.7) ng/mL vs. (32.9+/-11.4) ng/mL; hsCRP: (1.45+/-1.21) mg/L vs. (2.37+/-1.45)mg/L], and there was a significant difference in the latter two parameters between the 2 groups(P<0.01). In the patients with newly diagnosed T2DM, after matching blood pressure, blood sugar, and blood lipid, the levels of serum sCD14, sE-selectin, and hsCRP in the obese group were higher than those in the non-obese group. There was no significant difference in the former 2 parameters between the 2 groups. The serum sE-selectin was correlated with fasting blood sugar (r=0.369, P<0.001), 2-hour postprandial blood sugar (r=0.421, P<0.001), glycosylated hemoglobin (r=0.291, P=0.005), sCD14(r=0.312, P=0.002), and homeostasis model assessment-insulin resistance(r=0.247, P=0.018) in the newly diagnosed T2DM group. Stepwise regression ana-lysis showed that the serum sCD14 was one of the chief influencing factors on serum sE-selectin.@*CONCLUSION@#Serum sCD14 levels tend to increase in newly diagnosed T2DM patients, especially in the obese diabetic patients, which is one of the chief influencing factors to induce the injury of vascular endothelial cells. The innate immunity mediated by Toll-like receptor 4 may take part in the injury of vascular endothelial cells in newly diagnosed T2DM patients.

Objectives To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on β cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism. Methods Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII. Serum soluble E-selectin (sE-selectin) was used to evaluate the injury of vascular endothelial cell, while serum high sensitivity C reactive protein (hsCRP) and soluble CD_(14) (sCD_(14)) were both used to assess inflammatory condition. Results (1) Compared with those before treatment, the blood glucose levels of IVGTT, the area under the curve of the blood glucose, glycosylated hemoglobin, TC and LDL-C in the patients were decreased after CSII (P < 0. 05 or 0. 01). (2) Compared with those before treatment, the insulin levels of IVGTT (except the fasting insulin), the area under the curve of insulin and acute insulin response were all increased after CSII(P < 0.05 or 0.01). (3) Compared with that before treatment, the glucose infusion ratio in the clamp test [(3.46±1.66)mg·kg~(-1)·min~(-1) increased to (7.14±2.37)mg·kg~(-1)·min~(-1)]and HOMA-β elevated, while HOMA-IR declined (P <0. 05 or 0. 01 in all). (4) Compared with those before treatment, the levels of serum sE-selectin, sCD_(14) and hsCRP were decreased (P < 0. 01, except for hsCRP) . Conclusion Transient intensive insulin therapy in patients with newly diagnosed T2DM is useful to restore 13 cell function, attenuate insulin resistance, repair vascular endothelial injury and improve the disorder of blood sugar and lipid. The mechanism may be related with the inhibition of inflammation in patients.
ABSTRACT
Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2 years, PAI-1 4G/4G genotype may be a negative predictor for the progression of CCA-IMT in T2DM patients.
ABSTRACT
Objective To investigate the role of polymorphisms of scavenger receptor class B gene CD36 in affecting the progress of subclinical atherosclerosis (AS) and the associated factors affecting the expression of CD36 on the surface of peripheral blood monouclear cells (PBMC) and the association between CD36 expression and progress of subclinical AS in type 2 diabetic patients.Methods CD36 polymorphisms (CD36-rs1984112, CD36-T620C) were typed by PCR-RFLP in 470 cases of type 2 diabetes mellitus and 220 non-diabetic controls of Hans in Hunan area.The genotypes and allele frequencies were compared between cases and controls.Fluorescence intensity of CD36 on the surface of PBMC was analyzed in 102 cases of type 2 diabetes mellitus by flow cytometry and was compared between the patients without AS and the patients with subclinical AS.Multiple linear regression was applied to evaluate the relevant factors contributing to CD36 expression.Results The genotypes and allele frequencies of CD36-rs1984112 in type 2 diabetes mellitus were not significantly different between cases and controls (P＞0.05), either did CD36-T620C (P＞0.05).The mean florescence intensity (MFI) of CD36 in type 2 diabetics with subclinical AS was higher than that without AS (1 382±659 vs 1 173±340, P＜0.05).Factors affecting the CD36 expression were: age (P=0.005), gender (P=0.021), systolic blood pressure (SBP) (P=0.027), standardized coefficients Beta was 0.28, 0.31 and -0.21, respectively.Age contributed to the CD36 expression level in males (P=0.002) and diastolic blood pressure in females (P=0.001) respectively.Conclusion CD36-rs1984112 and T620C seem not to be a functional polymorphism sites in Hans of Hunan, southern China.CD36 expression level is higher in type 2 diabetics with subclinical AS in contrast with those without AS.CD36 expression on PBMC surface is higher in aged males with lower SBP.
ABSTRACT
Objective To explore the characteristics of proinsulin secretion in latent autoimmune diabetes in adults (LADA). Methods Fasting and 2 h sera in oral glucose tolerance test from 36 LADA patients, 37 type 2 diabetic patients and 43 healthy controls were collected to test glucose, proinsulin (PI) and C-peptide (CP) by radioimmune assay. Glutamie acid decarboxylase antibodies (GAD-Ab) were determined by radioligand assay.Results (1) Fasting proinsulin (FPI) and 2 h proinsulin (PPI) level in LADA patients were lower than those in type 2 diabetic patients (P<0.05), being both significantly inereasad compared with healthy controls (P<0.05 or P<0.01); The ratios of FPI/FCP and PPI/PCP (%) in LADA were beth significantly higer than those of type 2 diabetes mellitus and controls (P<0.05 or P<0.01); (2) LADA type-1 (GAD-Abe>0.3) patients showed lower PI levels(P<0.05 or P<0.01) and higher PI/CP ratio (all P<0.05) than LADA type-2 (0.05≤GAD-Ab<0.3); Meanwhile, there were no significant differences in above parameters between LADA type-2 and type 2 diabetes meUitus (P>0.05). (3) GAD-Ab index was negatively correlated with FPI and PPI in LADA group (r=-0.236 and-0.268, both P<0.05), and positively correlated with PPI/PCP (r=0.254, P=0.030).Meanwhile BMI was positively correlated with FPI, PPI and PI/CP in type 2 diabetes mellitus (all P<0.01). No factor entered the multiple regression analysis for predieting the hyperproinsulinemia and dispropriately elevated proinsulin levels in LADA patients. (4) According to the 99.5 th percentile of proinsulinemia in the healthy controls, which is defined as the cutoff point dispropriately elevated proinsulin levels, the proportion of subjects with fasting dispropriately elevated proinsulin levels (FPI/FCP) were 77.8%, 62.2% and 2.3% in LADA, type 2 diabetes meUitus and controls respectively, and PPI/PCP 83.3%, 51.4% and 2.3% respectively. Conclusion LADA patients, as well as type 2 diabetic patients, all showed hyperproinsulinemia and disproportionately elevated proiasulin levels that were one of characteristics of defective β-cell function. Moreover, disproportionately elevated nproinsulin level is more evident in LADA patients than that in type 2 diabetics and this may be related to humoral immunity.
