OBJECTIVE:To explore the effects of dual-phase insulin aspart with different dosing regimens on the related indica-tors of type 2 diabetic (T2DM) patients with poor glycemic control. METHODS:70 T2DM patients with poor glycemic control were randomly divided into group A and group B. All patients were given metformin and stopped other antidiabetic drugs;based on it,group A was additionally given Dual-phase insulin aspart injection,0.5 U/(kg·d),in the morning and evening before a meal by subcutaneous injection;group B was given Dual-phase insulin aspart injection,0.5 U/(kg·d),once before lunch time for 6-10 U and other twice in the morning and evening before a meal by subcutaneous injection. Both groups were treated for 12 weeks. Glu-cose control rate,glucose control time,and glucose indicators,daily fluctuations of glucose before and after treatment and incidenc-es of hypoglycemia and adverse reactions in 2 groups were observed. RESULTS:Glucose control rate in group B was significantly higher than group A,glucose control time was significantly shorter than group A,incidence of hypoglycemia was significantly low-er than group A(P<0.05). After treatment,glucose indicators and daily fluctuations of glucose in 2 groups were significantly lower than before,and group B was lower than group A(P<0.05). There were no obvious adverse reactions during treatment. CONCLU-SIONS:Conpared with 2 times a day,Dual-phase insulin aspart with 3 times a day for administration can effectively improve the glucose control rate and glucose levels in the treatment of T2DM patients with poor glycemic control,with good safety.

0.05). Conclusions:Compared with normal esophageal mucosa, the expression of HSP27 mRNA in esophageal squamous carcinoma and mucosa with atypical hyperplasia was markedly decreased.This indicated that the expression of HSP27 mRNA to a greater or less extent lost in the carcinogenesis and development of esophageal squamous carcinoma. To up-regulate the expression of HSP27 mRNA in esophageal squamous carcinoma may be a very effective biological therapy.

The association of plasma tissue type plasmingogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) with carotid atherosclerosis in patients with type 2 diabetes was explored.The subjects with type 2 diabetes (n =91) and control subjects (n =30) were enrolled for this study.According to carotid artery intima media thickness in Color Doppler Ultrasonography,the subjects with type 2 diabetes were divided into four groups:normal carotid group(group 1,n =25),lining thickening group (group 2,n =30),stable plaques group (group 3,n =23),carotid stenosis group(group 4,n =13).Plasma t-PA and PAI-1 levels were measured by ELISA.Compared with the control group,there was no significant change in the levels of plasma t-PA and PAI-1 in group 1 (P＞0.05),plasma t-PA activity was decreased significantly(P＜0.05) and PAI-1 activity increased obviously (P＜0.05) in group 2,group 3,and group 4.Carotid atherosclerosis degree was negatively correlated with t-PA(r=-0.723,P＜0.01) and positively correlated with PAI-1 (r=0.851,P＜0.01).The results suggested that the abnormal fibrinolysis function may take part in the development of atherosclerosis of carotid arteries in patients with type 2 diabetes.

OBJECTIVETo explore the central regulatory mechanism of electroacupuncture (EA) on patients with post-traumatic stress disorder (PTSD).

METHODSFourteen patients of PTSD were selected as study objects and treated with "regulating mind and restoring consciousness" acupuncture method, in which Baihui (GV 20) and Shenting (GV 24) were used as main acupoints and Sishencong (EX-HN 1) and Fengchi (GB 20) were used as supporting acupoints for acupuncture. After the arrival of qi, Han's acupoint nerve stimulator was connected for 30 min per treatment, three times a week for consecutive 12 weeks. Before treatment and 12 weeks into treatment, the clinician administered PTSD scale (CAPS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were evaluated; a Siemens 3.0 T magnetic resonance imaging system was used to perform resting-state scan, and bilateral hippocampus were taken as region of interested to perform encephalic function connectivity analysis.

RESULTSAfter the treatment, the scores of CAPS, SAS and SDS were all reduced compared with those before treatment (all P<0.05) ; function connectivity was enhanced in bilateral hippocampus, right posterior central gyrus and left superior parietal lobule (2.3

CONCLUSIONElectroacupuncture has certain improving effects on PTSD symptoms, which is likely to be related with enhancing the connectivity between parietal lobe and hippocampus, suppressing the connectivity between hippocampus and parahippocampal gyrus, amygdaloid, leading to an indirect influence on limbic system.

Objective To compare the short-term safety and efficacy of radiofrequency ablation (RFA) and microwave ablation (MWA) for treatment of large benign thyroid nodules.Methods A total of 34 patients with large benign thyroid nodules were studied retrospectively,including 13 patients treated with ultrasound-guided RFA and 21 patients treated with MWA between Jun.,2016 and Feb.,2017 in Zhongshan Hospital.The thyroid function parameters,serum antibodies,complications and thyroid nodules volume reduction rate(VRR) were compared between the two groups during the follow-up.Results There were no statistically significant differences(P＞0.05)among those patients before and after treatment in serum free triiodothyronine (fT3),free thyroxine (fT4),thyroid stimulating hormone (TSH),anti-thyroglobulin antibodies (TG-Ab) levels,and thyroid peroxidase antibodies (TPO-Ab).One patient in the MWA group had mild hoarseness after ablation and another patient in the RFA group had intraoperative hemorrhage for about 10 mL.There were no other complications such as neck scar,postoperative infection,skin burns,tracheal and esophageal injury.One day after the ablation,all nodules were showed hypoecho and contrast-enhanced ultrasound proved there was no blood supply.One month after treatment,no statistically significant difference was found in VRR between two groups (23.8％ vs.22.6％,P =0.127).Conclusions RFA and MWA are safe and effective treatments for large benign thyroid nodules,and no significant difference was observed in short-term follow-up.

Objective To study the effect of camphor oil in killing Demodex in vitro and to further analyze the killing mechanism.Methods The mites were collected with adhesive cellophane tape and randomly divided into six groups.The killing effect of camphor oil was investigated with different concentrations against Demodex in vitro.The reaction progress was pictured using Motic Images software.Results Camphor oil had better killing effect on Demodex folliculorum than on D.brevis in vitro.The death rate increased with the drug concentration and time.The most suitable and effective concentration of killing both Demodex folliculorum and D.brevis in vitro was 12.5%.After the drug was given,the mites contracted and twisted,and then relaxed and died.Conclusion Camphor oil has strong killing effect on Demodex in vitro.The main mechanism of camphor oil may be related to direct contact and neuromuscular toxicity.

Objective To explore the effects of deoxynivalenol (DON) on apoptosis of human gastric carcinoma cell line SNU in vitro. Methods SNU cells were treated with DON at different concentrations (50, 100, 1000, 2000 μg/L) for 12 hours, and then cells were harvested for cell apoptosis by flow cytometric (FCM) DNA analysis and the expression of Bax, Bcl-2 and Caspase-3 at protein level with FCM and Western blotting. Results FCM results showed that the apoptosis rates of SNU cells in DON treatment groups were all higher than that in control, especially in DON 1000 μg/L and 2000 μg/L groups (P<0.05). In the concentration range from 50 to 2000 μg/L, a significant concentration-depended response correlation could be found between apoptosis rate and DON concentration (r =0.940, P <0.01). FCM and Western blotting showed Bax and Caspase-3 expression in often SNU cells DON treatment for 12 hours were up-regulated while that of Bcl-2 was down-regulated. Conclusion DON can induce apoptosis of SNU cells in vitro in dose-dependent manner, and possible mechanisms of apoptosis induction effects may be up-regulation of the expression of Bax and down-regulation of that of Bcl-2 and activation of the key enzyme of apoptosis Caspase-3.

Objective To evaluate the application of three dimensional time-of-flight (3D-TOF) MRA in screening intracranial aneurysms in the population of Wenling community. Methods A total of 2 124 patients with suspicious intracranial aneurysm in Wenling community, who received 3D-TOF MRA and three dimensional digital subtraction angiography(3D-DSA) during the period from September 2011 to August 2012, were enrolled in this study. The epidemic data of intracranial aneurysm in Wenling community were analyzed, the effectiveness of 3D-TOF MRA in detecting intracranial aneurysm was assessed, and the consistency between 3D-TOF MRA and 3D-DSA (regarded as the golden standard) in detecting intracranial aneurysm was statistically analyzed. Results The results of 3D-TOF MRA showed that the morbidity of intracranial aneurysm in the population of Wenling community was 6.87% (146/2 124), among which the morbidities in males and females were 48.63% (n=71) and 51.37% (n=75) respectively; the mean age of patients was (41.2±11.6) years old. The accompanying diseases included hypertension, diabetes mellitus, arteriosclerosis and cerebrovascular lesions. 3D-TOF MRA examination revealed 149 intracranial aneurysms, among which misdiagnosis was made in 5 patients and missed diagnosis in 2 patients. The sensitivity, specificity and accuracy of 3D-TOF MRA in diagnosing intracranial aneurysm were 98.63% (144/146), 99.72%(1 773/1 778) and 99.67%(2 117/2 124) respectively. No statistically significant difference in measuring the longitudinal diameter and neck width of intracranial aneurysms existed between 3D-TOF MRA and 3D-DSA examinations (P>0.05). Conclusion In detecting intracranial aneurysm, 3D-TOF MRA carries higher sensitivity, specificity and accuracy, and its non-invasive advantage is more suitable for the screening of intracranial aneurysms.

Objective To investigate the curative effect of transcatheter arterial chemoembolization (TACE) combined with endovascular 125I seed strip implantation for the treatment of primary hepatocellular carcinoma (PHC) complicated by extensive portal vein tumor thrombus. Methods The clinical data of 72 patients with PHC complicated by extensive portal vein tumor thrombus were retrospectively analyzed. The patients were divided into group A (n=32) and group B (n=40). TACE combined with endovascular 125I seed strip implantation was performed for the patients of group A, while only TACE was employed for the patients of group B. The changes of portal vein tumor thrombus, the survival time and procedure-related adverse events were recorded. The preoperative and postoperative measured values were compared using paired samples t test, the count data were evaluated by χ2 test, and the survival time was analyzed with Kaplan-Meier method. Results Technical success rate of portal vein 125I seed strip implantation was 100%. No serious procedure-related adverse events occurred. The median survival periods of group A and group B were 210 days and 141 days respectively, the difference between the two groups was statistically significant (P=0.012). Conclusion For the treatment of primary hepatocellular carcinoma complicated by extensive portal vein tumor thrombus, TACE combined with endovascular 125I seed strip implantation can significantly improve the patient’s survival time.
