ABSTRACT

Objective:To describe the current status and efficacy of additional acarbose combined with insulin therapy in adult patients with type 1 diabetes mellitus (T1DM) .Methods:Adult T1DM patients with acarbose combined with insulin (acarbose group) or insulin alone (insulin group), age≥18 years and disease course≥1 year, who were registered in the T1DM Translational Medicine Research Project of Guangdong Province from June 2011 to December 2014 were enrolled in the study. The hemoglobin A1c (HbA 1c), body weight, body mass index (BMI), waist-to-hip ratio (WHR), insulin dosage and hypoglycemia of acarbose group and insulin group after 1 year were compared. Results:A total of 717 adult patients with T1DM were included (62 cases in acarbose group and 655 cases in insulin group). At the time of enrollment, the onset age of acarbose group was higher than that of insulin group [(31.1±12.3)years vs (27.4±12.4)years, P=0.019]; There were no significant differences in gender, age, course of disease, body weight, BMI, WHR, proportion of carbohydrate heat ≥50%, proportion of exercise time ≥150 min per week, HbA 1c, dosage of insulin, occurence of hypoglycemia and proportion of patients with dyslipidemia between the 2 groups (all P>0.05). After 1 year of follow-up, the HbA 1c in acarbose and insulin group decreased from baseline ( P=0.014, P<0.001), the body weight and BMI increased from baseline (all P<0.05), but WHR, insulin dosage and hypoglycemia occurrence were not statistically significant between the two groups (all P>0.05). After 1 year of follow-up, there were no significant difference in changes of HbA 1c, body weight, BMI, WHR, insulin dosage and hypoglycemia occurrence in acarbose group compared with insulin group from baseline (all P>0.05). Conclusions:In the clinical practice of T1DM treatment, acarbose is used more frequently in patients with a slightly older age of onset. Treatment of T1DM with insulin combined with acarbose did not increase the incidence of hypoglycemia, and no benefit was observed in improving HbA 1c, maintaining body weight, and reducing insulin use.

ABSTRACT

Objective@#To investigate the effect of pediatric early warning score(PEWS) on the evaluation of severity of emergency children admitted to pediatric intensive care unit(PICU).@*Methods@#A total of 1 069 cases hospitalized through emergency room into PICU in Guiyang Children′s Hospital, from January to December in 2017 were analyzed, and the PEWS was recorded for the first time in emergency room and PICU, while receiver operating curve was used to analyze the efficacy of PEWS to diagnose the children, who were at risk of clinical deterioration and required transfer to the PICU, which included the sensitivity, specificity, Youden index.The diagnostic value of PEWS in asse-ssing the severity of disease in critically ill children was explored.@*Results@#The 1 069 severe cases of PICU ranged from 1 month to 13 years and 8 months, and PEWS score was (4.6±0.8) scores in the emergency room, and (5.1±0.5) scores in the PICU, so there were significant differences of the PEWS score between the death group [(8.0±0.5) scores] and the survival group [(4.8±0.8) scores] in the emergency room and PICU(all P<0.05). The PEWS score of the respiratory, nervous, circulatory and digestive system groups in PICU was (5.8±0.5) scores, while other systemic diseases (blood, kidney, poisoning, and so on) PEWS score was(4.2±0.5) scores; which showed significant differences between 2 groups(t=4.60, P<0.05). In PICU, the score of PEWS was greater than or equal to 4.7, which was the demarcation point to distinguish the critical condition and predict the death risk of the patient.@*Conclusions@#PEWS is of great significance for assessing the children sent to PICU.Patients with mainly respiratory, circulatory, neurological, and digestive system diseases have higher PEWS scores.The PEWS score of other system diseases is significantly reduced.It is suggested that PEWS is not able to reflect the disease of such a system and needs to be taken seriously.

ABSTRACT

Objective The management of poor-grade ruptured aneurysm is important and challenging in intravascular inter-vention. This study aimed to investigate the safety of external ventricular drainage(EVD)after stent-assisted embolization for patients with poor-grade ruptured aneurysm in the acute stage. Methods From January 2015 to July 2017,27 patients with poor-grade rup-tured aneurysm underwent EVD after endovascular embolization by stent-assisted coiling(n=14)or simple coiling(n=13). We com-pared the clinical data about and the postoperative complications between the two groups of patients. Results There were no statisti-cally significant differences in the patients'age,gender,Glasgow Coma Scale(GCS)scores before embolization and discharge,the in-terval between EVD and the end of embolization,preoperative intraventricular hemorrhage and hydrocephalus,puncture-related bleed-ing after EVD,catheter-indwelling time,perioperative bleeding in other parts,or poor prognosis between the stent-assisted coiling and simple coiling groups(all P>0.05). Conclusion EVD after stent-assisted embolization is a relatively safe strategy for the treatment of poor-grade ruptured aneurysm in the acute stage.

ABSTRACT

Hoxa3-Pax1/Pax9-Eya1-Six1/4 regulatory pathway seems to be operating during forming the bilateral parathyroid/thymus common primordial in early embryonic development.The specification of the parathyroid domain in the parathyroid/thymus primordial is regulated through a Shh-Tbx1-Gcm2 pathway.Gcm2 also may play roles in later steps of parathyroid development,including CaSR and PTH gene expression.MafB and Gcm2 interact with each other and synergistically activate PTH transcription.Genetic basis and the etiology of some hypoparathyroid disorders in man are involved defects in transcription factors that include GCMB,GATA3,Tbxl,SOX3 and GNA11.This marker expression in thymus and parathyroid primordium includes HoxA3,Pax1,Eya1,and Six1;and expression of parathyroid cell-like cells includes Gcm2,CaSR,and PTH.These expressions may serve as markers of stem cell differentiation into parathyroid cell-like cells.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the indications, safety and efficacy of catheter directed thrombolysis for early left lower extremity deep venous thrombosis (DVT) without vena cava filters protection.</p><p><b>METHODS</b>Clinical data of 54 cases of early left lower extremity DVT received catheter directed thrombolysis without vena cava filters from July 2008 to June 2010 were retrospectively analyzed. The thrombosis was entire without free floating clots and no thrombosis in vena cava detected with ultrasound scan. Twenty-five patients were male and 29 were female with the average age of 52.8 years. Fifty-one of which were iliofemoral and popliteal, the other 3 were iliofemoral. The course were ≤ 7 d in 45 cases and these were 8 to 30 d in 9 cases. Urokinase of 300 000 U was infused through catheters per 2 h twice a day. Meanwhile 4000 U of low weight heparin was administered subcutaneously per 12 h, or heparin infusion at dosage of 18 U×kg(-1)×h(-1).</p><p><b>RESULTS</b>The procedure technically succeeded in all patients. In total cases venous score decreased to 4.6 ± 2.1 post 6 to 10 d of thrombolysis from 10.8 ± 1.0 with thrombolysis rate of 58% ± 18% which was not significantly different between groups of ≤ 7 d and 8 to 30 d (t = 1.02, P = 0.34). On 14(th) day, 11 patients (20.4%) completely recovered, 35 cases (64.8%) experienced large improvement, 8 patients (14.8%) had mild improvement and nobody was failed, resulting in total efficacy of 100%. No patient developed clinical symptomatic pulmonary embolism. SpO2 did not alter markedly post thrombolysis [(91.0 ± 2.6)% vs. (90.8 ± 2.4)%, t = 2.03, P = 0.05]. No patients suffered from cerebral hemorrhage and haemoturia, and catheter induced inflammation occurred in 4 cases (7.41%). There was mild bleeding in puncture sites in 11 patients (20.4%) during the course. There were 36 patients (66.7%) had been followed up with the time of 6 to 21 months. In which 31 cases had no lower extremity edema or had mild edema after activities. Two patients developed serious edema after activities for deep venous insufficiency. Three cases combined with malignant tumor or renal failure recurred.</p><p><b>CONCLUSIONS</b>For early left extremity DVT which is entire without free floating clots and no thrombosis in vena cava, catheter directed thrombolysis without filter protection maybe administered with safety, efficiency and lower expense.</p>

ABSTRACT

ObjectiveTo investigate the application of rapid immunohistochemical staining technique in intraoperative frozen section diagnosis of thyroid neoplasm.Methods MaxVision one-step rapid immunohistochemical staining technique was used to detect the expression of CK19,HBME-1,and Gal-3 in frozen section of papillary thyroid carcinoma(PTC)andthyroid benign lesions.MaxVision conventional immunohistochemistry of frozen remaining tissue was served as control.ResultsMaxVision one-step rapid immunohistochemical staining technique could be completed in 20 minutes.The positive localizations of three markers detected by rapid immunohistochemistry were similar to conventional immunohistochemistry, in general.The expression of CK19 was located in cytoplasm and cellular membrane.Gal-3 and HBME-1 were mainly detected in follicular luminal border and/or surface of papilla. The staining intensity in rapid immunohistochemistry was stronger than that in conventional immunohistochemistry. The positive rates of CK19,HBME-1,and Gal-3 by rapid immunohistochemistry in frozen sections were: 0 (0/28),10.7 % (3/28),0 (0/28),respectively,for benign lesions (nodular goiter,Hashimoto thyroiditis,thyroid adenoma); and 94.9 %(37/39),92.3 % (36/39),92.3 % (36/39),respectively,for PTC.The expression of three markers between thyroid benign lesions and PTC had a significant difference (x2 =59.326,55.861,44.605,all P < 0.001).In benign lesions,the rate of same case with two and more positive markers was 0,while in PTC it was 100 % and significantly different (x2 =67.000,P < 0.05).ConclusionMaxVision one-step rapid immunohistochemical staining technique could be applied in intraoperative frozen section diagnosis.Detecting CK19,HBME-1,and Gal-3 expression in intraoperative frozen section has an auxiliary value for diagnosis of PTC.

ABSTRACT

Objective To evaluate traditional surgical treatment, intraluminal strategy and hybrid operation on revascularization of atherosclerosis obliterans (ASO) of the lower extremity. Methods Clinical data of 197 ASO cases receiving revascularization from January, 1998 to December, 2008 were retrospectively analyzed. Seventy-seven cases underwent surgical treatment, 82 cases received intraluminal therapy, and 38 cases were treated by hybrid operation. The indications, clinical effect, complication and perioperational mortality of these three strategies were evaluated. Results 71% patients (164 cases) were followed up from 2 to 112 months. Surgical and intraluminal method had no statistical difference on long-term patency of aortic-iliac and femoral-popliteal artery (57% vs. 51%;48% vs. 42%). Hybrid procedure led to higher patency on multi-level lesion and concurrent thrombosis. The complications after surgery was higher than intraluminal on aortic- iliac and femoral-popliteal artery (31% vs. 12%;31% vs. 11%), and higher than intraluminal and hybrid on multi-level lesion (36% vs. 12% vs. 15%). The perioperative mortality of surgical group was 1.5% and 2.0% on aortic-iliac and multilevel lesion and 0% on other site;and that of intraluminal and hybrid procedure was 0%. Conclusion For aortic-iliac and femoral-popliteal artery revascularization, surgery was preferred in cases of long occlusive lesion and intervention was preferred for cases with short non-occlusive lesion. Hybrid procedure was the best for multi-level and concurrent thrombosis.

ABSTRACT

<p><b>BACKGROUND</b>Arthritogenic T lymphocytes with common T cell receptor (TCR) Vbeta clonotypes, infiltrating in the articulars of rheumatoid arthritis (RA) patients, play a central role in the pathogenesis of RA. TCR Vbeta5.2 and TCR Vbeta8.2 are the main pathogenic T cell clonotypes in the course of collagen-induced arthritis (CIA) progression in Lewis rats. To investigate a TCR-based immunotherapy for RA, we constructed recombinant DNA vaccines encoding TCR Vbeta5.2 and TCR Vbeta8.2, and evaluated the inhibitive effects of the two vaccines on CIA rats.</p><p><b>METHODS</b>Genes encoding TCR Vbeta5.2 and TCR Vbeta8.2 were amplified by RT-PCR from spleen lymphocytes of Lewis rats and cloned into the eukaryotic expression vector pTargeT. The expression of vaccines was confirmed by RT-PCR and immunohistochemistry. The inhibitive effects of the vaccines on articulars of CIA rats were assessed with arthritis index evaluation and histology. Interferon gamma (IFN-gamma) and interleukin (IL)-4 production by spleen lymphocytes were tested with enzyme-linked immunospot assay (ELISPOT) technique, the changes in peripheral CD4(+) and CD8(+) lymphocyte populations were tested by flow cytometry, and the level of anti-CII antibody in serum was assayed by enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>Recombinant DNA vaccines pTargeT-TCR Vbeta5.2 and pTargeT-pTCR Vbeta8.2 were successfully constructed. Both vaccines inhibited CIA, which alleviated the arthritis index score (P < 0.05), decreased the level of IFN-gamma (P < 0.05), and reduced the ratio of CD4(+)/CD8(+) lymphocytes (P < 0.05) and the anti-CII antibody in serum (P < 0.05). In addition, the histological change in DNA-vaccinated rats was less serious than CIA rats. Compared to pTCR Vbeta 8.2 and pTCR Vbeta 5.2 groups, the group that was injected with a combination of the two vaccines showed stronger inhibitive effects on CIA than either individual vaccine.</p><p><b>CONCLUSION</b>The recombinant plasmids pTargeT-TCR Vbeta5.2 and pTargeT-TCR Vbeta8.2 have obvious inhibatory effects on CIA rats and better effects could be achieved when the vaccines were used in combination.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of energy controllable steep pulses (ECSP) in the treatment of rabbit VX2 cancer implanted in livers.</p><p><b>METHODS</b>A tumor model was successfully established using 30 rabbits. ECSP were applied to liver cancer in half of these rabbits and the rest were used as controls. After exposure to ECSP, tissues were obtained and subjected by routine HE and transmission electron microscopic (TEM) observation. The survival time of the animals and the statuses of each group were recorded.</p><p><b>RESULTS</b>From pathological observations, ECSP showed effectively destructive action compared with that of the unexposed group. A clear borderline can be seen between necrotic cancer and its surrounding normal tissue. Irreversible cell changes were present under TEM. The survival periods of the experimental and control group were 83.1 days and 39.0 days respectively, and there was a significant difference between the two groups (Z = -2.943, P < 0.01).</p><p><b>CONCLUSION</b>ECSP can effectively treat rabbit VX2 cancer implanted in the liver; also it is safe for its surrounding normal tissues. ECSP can be a useful method for local treatment of liver cancer.</p>
