AIM: To evaluate the effects of glycemic control on refraction in diabetic patients. METHODS: Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose, HbA1c levels, fasting C-peptide and postprandial 2h C-peptide were measured before treatment. The patients with random blood glucose higher than 12.0mmol/L and HbA1c level higher than 10.0% were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1, 2, 3 and 4 during glycemic control.RESULTS: A transient hyperopic change occurred in all the patients receiving glycemic control. The maximum hyperopic change was 1.60D (range 0.50±3.20D). Recovery of the previous refraction occurred between two and four weeks after insulin treatment. There was a positive correlation between the maximum hyperopic changes and the HbA1c levels on admission (r=0.84, P<0.05). There was a positive correlation between the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment (r=0.53, P<0.05). During transient hyperopia, no significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length.CONCLUSION: Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of the blood glucose level.

Cheng and Church algorithm is an important approach in biclustering algorithms.In this paper, the process of the extended space in the second stage of Cheng and Church algorithm is improved and the selections of two important parameters are discussed. The results of the improved algorithm used in the gene expression spectrum analysis show that, compared with Cheng and Church algorithm, the quality of clustering results is enhanced obviously, the mining expression models are better, and the data possess a strong consistency with fluctuation on the condition while the computational time does not increase significantly.

ObjectiveTo evaluate the functional changes of stunned myocardium before and after coronary artery bypass graft(CABG) treatment,and clear the meaning of revascularization which CABG has brought to patients with diffused vascular changes.MethodsA total of 36 patients with 99％ diffused coronary artery stenosis in left anterior descending branch underwent non-pump CABG treatment in the Department of Cardiothoracic Surgery the First affiliated hospital of Harbin Medical University.Real-time three-dimensional echocardiography (RT3DE) was repeatedly performed 1 week before operation and 10 days,1 month,and 3 months after CABG.Regional diastolic volumes,systolic volumes,ejection fractions,regional stroke volume to global diastolic volume and the values of abnormal segments before and after CABG were studied.ResultsOne week before operation and 10 days,1 month and 3 months after CABG,the differences of volumes between groups in the last phases of diastole and systolic were statistically significant in anterior wall basement segment,anterior septal basement segment,anterior wall intercalary segment,anterior septal intercalary segment,anterior wall of apex cordis and septation of apex cordis(F =3.51,3.55,4.08,4.05,2.98,3.01,all P ＜ 0.05; F =4.51,4.55,4.08,3.00,2.96,2.99,all P ＜ 0.05).The values of the six segments mentioned above,3 months after operation[(6.74 ± 1.23),(6.64 ± 1.21),(6.02 ± 1.10),(5.95 ± 1.09),(5.82 ± 1.06),(5.10 ± 0.93)ml; (2.74 ± 0.50),(2.69 ± 0.49),(2.51 ± 0.46),(2.32 ± 0.42),(2.36 ± 0.43),(2.03 ± 0.37)ml] were compared with those of 1 week before operation[(8.33 ± 1.52),(8.20 ± 1.50),(7.43 ± 1.36),(7.36 ± 1.34),(7.19 ± 1.31),(6.29 ± 1.15)ml; (4.94 ± 0.90),(4.85 ± 0.88),(4.53 ± 0.83),(4.18 ± 0.76),(4.25 ± 0.78 ),(3.65 ± 0.67)ml],the differences were statistically significant (all P ＜ 0.05); the differences between groups in regional ejection fractions,regional-global ejection fractions were statistically significant(F =4.56,4.88,4.28,3.15,2.93,2.88,P ＜ 0.01 or ＜ 0.05; F =5.56,5.28,4.98,5.15,3.03,2.78,P ＜ 0.01 or ＜ 0.05).Compared with 1 week before the operation, 1 month after the operation in regional ejection fractions,10 days,1 month in regionalglobal ejection fractions after the operation,4 segments of them were significantly improved(all P ＜ 0.05) and 3 months after operation,all the 6 segments had been improved significantly(all P ＜ 0.05).The maximum volume of the sum of group difference of the 6 segments and the 4 segments in the last phase of diastole was statistically significant(F =2.58,5.81,P ＜ 0.05 or ＜ 0.01 ),and the summation began to decrease 10 days after the operation.The values of 3 months after operation[ (36.27 ± 1.10),(25.35 ± 1.16)ml] were compared with that of 1 week before operation[ (44.80 ± 1.36),(31.32 ± 1.43)ml ] the difference was statistically significant (all P＜ 0.05).The maximum volume summafion comparisons of 6 segments and 4 segments in the last phase of systolic had statistical significance(F =5.77,5.57,all P ＜ 0.01 ),and 10 days after the operation,the summation began to decrease.The values of 1 month[(16.4 0 ± 0.48),(11.58 ±0.51 )ml],and 3 months after operation[ (14.65 ± 0.45),(10.26 ± 0.46)ml],were compared with those of 1 week before operation[ (26.40 ± 0.80),(18.50 ± 0.84)ml],the differences were statistically significant (all P ＜ 0.05).ConclusionsStunned myocardium can be improved through CABG in myocardium systolic,diastole function and ejection fractions of the relevant segments and all of this have proved that patients undergoing CABG revascularization can improve the heart function of the ischemic area.

To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated. Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all <0.001).In the ultra-early stage after surgery,HCR was significantly higher in the KAES group(<0.001),whereas in the early and sub-early stage,HCR showed no significant differences(all >0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all >0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all >0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(=0.413). Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.
