The fibre projections of the caudate nucleus to the cerebral cortex and the nonspecific thalamic nucleus in the rabbit were studied by tracing the degenerated axons and terminal fibres from electrolytic lesions in the head portion of the nucleus on sections prepared with Nauta and Glees methods.The results were as follows:The efferent fibres from the head portion of the caudate nucleus were projected to frontal (especially the praecentral areas) and limbic cortex, and terminated in all the layers of the cerebral cortex.The efferent fibres from the head portion of the caudate nucleus were projectet to the centromedian nucleus and parafascicular nucleus of the nonspecific thalamic nuclei.The above observations suggest that the projection of the efferent fibres from the caudate nucleus to the cerebral cortex and nonspecific thalamic nuclei may be a parf of the nonspecific conducting pathway; and the caudate nucleus is not only a part do the extrapyramidal system but a structure of the nonspecific conducting system which may serve as the morphological basis for the role played by the caudate nucleus in the acupunctural analgesia.

Objective To explore the efficacy of captopril and methylprednisolone in the implosive therapy of RNS.Methods 21 cases of RNS who have captopril 1.25 mg/d and intravenous dripping methylprednisolone of 20mg/kg·d sustained 1-2h for 3 days,if non-remissions,using once more after a week.Results 21 cases of children with complete remission in 13 cases,partial remission in 5 cases,non-remission in 3 cases.The overall response rate was 86%.In complete remission 13 cases,4 cases remission after 2 courses treatment,5 cases remission after four courses treatment,4 cases remission after 6 courses treatment.Conclusion Combined captopril with methylprednisolone in treating refractory nephritic syndrome can improve the rate of remission.

Calculation of linear parameters, such as time-domain and frequency-domain analysis of heart rate variability (HRV), is a conventional method for assessment of autonomic nervous system activity. Nonlinear phenomena are certainly involved in the genesis of HRV. In a seemingly random signal the Poincaré plot can easily demonstrate whether there is an underlying determinism in the signal. Linear and nonlinear analysis methods were applied in the computer words inputting experiments in this study for physiological measurement. This study therefore demonstrated that Poincaré plot was a simple but powerful graphical tool to describe the dynamics of a system.

? Diabetic retinopathy is one of those significant complications of diabetes.With the increasing number of diabetic patients, blind caused by diabetic retinopathy is a serious threat to human health which cannot be neglected, but there is no highly effective treatment for it. Consequently, early detection and preventive treatment for it are important.Currently, studies have found that urine microalbumin had a close relation with diabetic retinopathy and that urine microalbumin might play an important role in early predicting of diabetic retinopathy. The review is about the diagnostic significance of urine microalbumin test for early diabetic retinopathy.

Objective To evaluate the effect of bandage rollers compression on pocket hemostasis in patients after implantation of permanent pacemaker.Methods A total of 591 patients after implantation of permanent pacemaker were enrolled in this study and divided into trial group and control group.The wounds of 296 patients in trial group received compression by two bandage rollers,which were placed parallelly on the wound side by side,above the pocket of pacemaker,fixed by 3M adhesive tapes so that no bleeding of wound and no shifting of rollers.6 hours after the operation,the tapes and bandage rollers were released.The wounds of 295 patients in control group received compression by 1 000 g sand bag which were taken off 6 hours after the operation.The safety and effects of hemostasis in patients between the two groups were compared.Results The incidences of incision bleeding,pocket hematoma and pocket skin pressure injury were not significantly different between the two groups(P>0.05).The incidences of postoperative pain,urinary retention and insomnia were significantly different between the two groups(P<0.05).Conclusion The incidences of postoperative pain,urinary retention and insomnia are significantly reduced in patients who received bandage roller compression.

Objective To study effect of triple viable bacterium of bacillus (small peifeikang) on the intestinal microflora and inflammation factors in patients with infectious diarrhea.Methods From October 2010 to October 2014, 120 patients with infectious diarrhea were chosen as study objects, 30 cases of health examination were selected as healthy control group, All patients were divided into 2 groups:60 patients in small peifeikang group and 60 patients in control group.The therapeutic effect and the change of intestinal microflora and inflammation factors were compared between two groups.Results The effective rate of small peifeikang groupwas 100.00%, while that of control group was 96.67%,the difference had statistical significance (χ2 =5.52,P<0.05).The symptom disappearance time of diarrhea, vomiting and fever had statistical difference between two groups (P<0.05), that of dehydration had no statistical significance.After treatment, in small peifeikang group and control group, the number of bifidobacterium, lactobacillus, and B/E value had decreased significantly (P<0.05), and the number of intestinal bacteriahad increased significantly(P<0.05).The distribution of intestinal flora in small peifeikang group was better than that of control group, and the difference had statistical significance(P<0.05).After treatment, in small peifeikang group and control group, the level of endotoxin, IL -6, TNF-αand CRP had decreased significantly( P <0.05).The extent of decreasing in small peifeikang group was more significant than that of control group, and the difference had statistical significance ( P <0.05 ) . Conclusion The triple viable bacterium of bacillus can promote the recurrence of patients with infectious diarrhea by adjusting the distribution of intestinal microflora, and by its immune regulation function.

Glycosylated hemoglobin A1c(HbA1c)is the products of slow,continuous non-enzymatic saccharification reaction,which can reflect the average blood glucose of 2~3 months of the patients,and it is the most important index for long-term monitoring of glucose.There are so many methods for detecting HbA1c that America,Japan and Swede proposed their own standardized detection methods to reduce the difference laboratories.However,these methods were non-specific.A new method for was developed by International Federation of Clinical Chemistry and laboratory medicine (IFCC) in 2007,which was of high specificity,but which resulted in relatively low glycosylated hemoglobin.To avoid the confusion in reference value of glycosylated hemoglobin,average blood glucose was recommended by American Diabetes Association (ADA),European Association for the Study of Diabetes (EASD),and International Diabetes Federation (IDF).This paper review the origin of average blood glucose substituting HbA1c,relationship of HbA1c with average blood glucose,and the international multiple-center research of ADAG and its enlightenment,and we also discuss the relevant development in future.

Objective To investigate the bladder responses to different rates of bladder infusion in healthy and spinal cord injured rats.Methods Fourteen adult female Sprague-Dawley rats were used and divided into two groups:healthy group (n =7) and spinal transection injury group (n =7).The intravesical pressures induced by continuous infusion of saline with different rates under general anesthesia were recorded and compared between the two groups.Results In healthy group the responses of bladder contraction were dependent upon the rate of bladder infusion,and contraction time became shorter while increasing the infusion rate (P ＜ 0.05),i.e.contraction time was (401.0±132.4),(215.7 ±95.9),(108.3 ±59.1) and (52.5 ±32.8)s,respectively,when the infusion rate was 0.05,0.1,0.2 and 0.5 mL/min.Compared with healthy group,spinal transection injury group had significantly shorter bladder contraction time (P ＜ 0.05),however the relationship between bladder contraction time and infusion rate was much weakened.Spinal transaction injury rats had significantly lower peak of bladder pressure (P ＜ 0.05) compared with healthy rats.There was no significant difference for contraction durations between the two groups.Conclusions The infusion rates influenced the contraction periods for both healthy and spinal cord injured rats.During bladder infusions with a same rate,the contraction time and the peak of bladder pressure were determined by bladder conditions,i.e.healthy or neurogenic with spinal cord injury.

Objective To compare clinical value of peripheral blood collection and venous blood collection methods in blood tests.Methods 467 patients who received blood test were selected.The venous blood and peripher-al blood were collected,the indicators of blood test were detected,and the test results were analyzed.Results The white blood cell count (WBC),red blood cell count (RBC),platelet count (PLT),red blood cell hematocrit (HCT),hemoglobin (HB)of venous blood were (5.7 ±1.2)×109 /L,(3.72 ±0.48)×109 /L,(218.0 ±57.5)× 109 /L,(41.8 ±19.8)g/L,(115.7 ±13.8)g/L respectively,those of peripheral blood were (6.7 ±3.4)×109 /L, (3.62 ±0.72)×109 /L,(204.0 ±87.7)×109 /L,(32.7 ±20.7)g/L,(103.6 ±19.6),the differences were statis-tically significant (t =5.994,2.497,2.885,6.865,10.908,all P <0.05).The mean red cell hemoglobin concentra-tion (MCHC),mean red cell volume (MCV),mean erythrocyte hemoglobin (MCH)and other indexes had no signifi-cant differences(all P >0.05).Conclusion The test results in patients with venous and peripheral blood was quite different,venous blood test results obtained with greater value in clinical use,it is recommended that routine blood test used venous blood.
