Objective To assess the awareness of nutrition issues among patients with type 2 diabetes mellitus (T2DM) and to find effective nutrition education models. Methods According to cluster random sampling method,256 T2DM patients from 2 hospitals in Zhengzhou City were enrolled and randomly assigned to the study or control group. The participants in the study group received traditional nutrition education and real object-based diabetic diet guidance, and those in the control group received traditional nutrition education only. Awareness about nutrition and blood glucose levels were compared between the two groups by using independent t test and Chi-square test Results After the intervention, the study group showed significantly higher nutrition scores ( 86. 5 ± 3.8 vs 71.5 ± 4. 6, P ＜ 0. 05 ) and lower 2 h postprandial glucose level ( ( 9. 15 ± 1.06 ) mmol/L vs ( 11.32 ± 0. 84) mmol/L, P ＜ 0. 05 ). Conclusion Real object-based diabetic diet teaching could foster the awareness in nutrition and decrease postprandial blood glucose level in T2DM patients.

Three compounds were isolated from solid culture of endophyte Myrothecium roridum IFB-E091 in Artemisia annua. Their structures were determined as (S)-(-)-N-[2-(3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl)-ethyl]-acetamide (1), N-(4-hydroxyphenethyl)acetamide (2) and asperfumoid (3), in which compound 1 was a new indole derivative. In cytotoxicity assay, the compound 1 had no obvious inhibition activity in human hepatoma cell line SMMC-7721 and human cervical carcinoma cell line HeLa.

OBJECTIVETo explore the effect and mechanism of electroacupuncture (EA) for Z syndrome without organic lesion (metabolic syndrome combined with obstructive sleep apnea hypopnea syndrome).

METHODSFifty-eight patients with Z syndrome were divided into three groups according to mild,moderate and severe degree. Acupuncture and EA were used at Daimai (GB 26), Zhongwan (CV 12), Xiawan (CV 10), Zusanli ST 36), Qihai (CV 6) and Huaroumen (ST 24), etc., once a day and five times a week. The treatment of ten times was a course, and two courses were acquired continuously. Sleep respiration monitoring (PSG) was done before EA and in one week after treatment respectively. Triacylglycerol (TG) fasting blood glucose (FBG) fasting insulin (INS) and serum leptin (Lep) were tested before and after treatment in the three groups.

RESULTSAfter treatment apnea hypopnea index (AHI) and the percentage of the time of arterial oxygen saturation (SaO₂) less than 90% taken in the total sleep time (SLT 90%) were improved apparently than those before treatment in the three groups (all P < 0.05). The levels of TG, FPG, INS and Lep were decreased after treatment in all groups (all P < 0.05).

CONCLUSIONEA can improve AHI and nocturnal hypoxia of Z syndrome, and the mechanism may be related to decreasing the indices of metabolism syndrome and leptin.

BACKGROUND: Vascular restenosis alter carotid endarteractomy (CEA) is an important factor affecting curative affect ofoperation.OBJECTIVE: To explore the role of matrix metalloproteinase-9 (MMP-9) mRNA dynamic expression in the development of early vascular restenosis after carotid endarterectomy.DESIGN, TIME AND SETTING: A random grouping contrast observation was completed in the General Hospital of Beijing Military Area Command of Chinese PLA from February 2006 to December 2007. MATERIALS: Forty-one healthy male New Zealand rabbit, weighing about 3.0 kg, with 36 ones used for preparing carotid atherosclerotic stenosis (CASS) models. experimental group, each 6 of the CASS rabbit models (n =36) were selected at the time points of hour 4, day 1, 3, 7, 30, and 90 following CEA respectively. Then they were fixed with 40 g/L polyoxymethylene perfusion and stained with hematoxylin-eosin to observe their morphologic changes.MAIN OUTCOME MEASURES: The expression changes of MMP-9 mRNA were observed dudng the development of early vascular restenosis by the quantitative real-time polymerase chain reaction technique preoperatively as well as at day 1, 3 and 7 following CEA.RESULTS: Several stages could be seen in the reparative process of neointima after CEA, including the thrombosis, the inflammatory reaction, the repair of endothelium, the proliferation of vascular smooth muscle call, the formation and accumulation of extracellular matrix. MMP-9 mRNA was expressed since day 1, reached a peak at day 3 and then decreased significantly at day 7 postoperatively.CONCLUSION: MMP-9 plays an important role in the proliferation, migration and reconstruction of vascular smooth muscle calls, the mediated reconstruction of local blood vessels, as well as the development of vascular restenosis.

Objective: To detect the mutation of epidermal growth factor receptor (EGFR) gene in peripheral blood of non-small cell lung cancer (NSCLC) patients in Yunnan area with Super-ARMS, and to explore its correlation with clinicopathological characteristics. Methods: A total of 222 blood samples from patients with NSCLC were collected between January 2017 to December 2018 in the Molecular Diagnostic Center of Yunnan Cancer Hospital. The EGFR gene mutation in peripheral blood samples was detected by SuperARMS, and the relationship between EGFR gene mutation and clinicopathological features was analyzed. Meanwhile, the independent risk factors influencing EFGR mutation were also analyzed. Results: In the peripheral blood of 222 NSCLC patients, there were 81 cases (36.5%) with EGFR gene mutation. Among them, exon 19 deletion and L858R gene point mutation were the most common (75.3% of total mutation); female patients had a higher mutation rate than male patients (45.9% vs 27.0%); patients <60 years old had a higher incidence of mutation than patients≥60 years old (43.2% vs 28.8%) (P<0.05 or P<0.01); moreover, patients with no history of smoking, no history of radical surgery, adenocarcinoma, advanced stage and no history of chemotherapy had higher incidence of EGFR mutation (43.9% vs 21.6%, 39.2% vs 21.2%, 43.9% vs 4.8%, 39.7% vs 23.3% and 44.0% vs 23.5%) (P<0.05 or P<0.01). Multivariate logistic analysis showed that young, no smoking history, adenocarcinoma and no surgical history were independent risk factors for EGFR gene mutation (all P<0.01). Conclusion: In the peripheral blood of patients with NSCLC in Yunnan, the mutation rate of EGFR gene is higher in patients with age<60 years old, adenocarcinoma and non-smoking. Super-ARMS method is more sensitive in the detection of EGFR mutation in peripheral blood of lung cancer patients.

Objective To explore the clinical efficacy and safety of hyper-early embolotherapy in treatment of intracranial ruptured aneurysm.Methods A retrospective analysis was made on 33 patients with intracranial ruptured aneurysm.Preoperative Hunt-Hess grade:grade Ⅰ-Ⅱ in 16 patients,gradeⅢin 5 patients,grade Ⅳ in 9 patients,grade Ⅴ in 3 patients.All patients were confirmed with subarachnoid hemorrhage (SAH) by angiography and then underwent embolization under general anesthesia by detachable coils within 6 h from onset.Results After operation,25 patients (75.8％) recovered well,4 patients (12.1％) were with mild disability with paralysis and aphasia,4 patients (12.1％) were dead (1 patient for intraoperative aneurysm rupture,1 patient for postoperative pneumonia,1 patient for infection of hematoma at puncture site and 1 patient for postoperative gastrointestinal bleeding).Followed up 1-6 months,no rebleeding occurred.Conclusions Hyper-early embolotherapy could avoid rebleeding of the aneurysm,and relieve the vasespasm,without increasing the intra-operative rebleeding rate.Moreover hyper-early embolotherapy could greatly decrease the mortality of poor-grade SAH patients.

OBJECTIVETo evaluate the efficacy and safety of mechanical thrombectomy with the Solitaire AB device in recanalization of patients with acute ischemic stroke of posterior circulation.

METHODSThe clinical data of 17 consecutive patients with acute ischemic stroke of posterior circulation, treated with the Solitaire AB device from August 2011 to August 2015 in Department of Neurosurgery, the Military General Hospital of Beijing People's Liberation Army, were extracted and then retrospectively analyzed. There were 12 male and 5 female patients with a median age of 60 years (ranging from 44 to 75 years). Among them, 8 cases occluded in basilar artery, 4 cases occluded in vertebral artery and 5 cases occluded in vertebral plus basilar artery. Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after treatment, measured by National Institute of Health stroke scale (NIHSS) score, were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after treatment.

RESULTSFifteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath time were above 7.5 hours. The NIHSS score at 7 days was 11±10, which was significantly decreased compared to the admission NIHSS score 17±5 (t=2.949, P=0.009). No symptomatic intracranial hemorrhage case was found after thrombectomy. At 90 days, one patient died(mRS 6), one patient seriously disabled (mRS 5), two patients moderately seriously disabled (mRS 4), four patients resulted in moderate outcome (mRS 3) and the other 9 patients achieved good outcome (mRS 0 to 2). The dead and seriously disabled cases were both due to failure in recanalization. Two moderately seriously disabled cases were probably attributed to their severe admission condition (NIHSS >20) and prolonged time (onset to sheath time >6 hours).

CONCLUSIONMechanical thrombectomy with the Solitaire AB device contributes to a high rate of recanalization with a low probability of complication and improves functional outcome in patients with acute ischemic stroke of posterior circulation.
