Objective Studying the related factors of left ventricular hypertrophy for hypertensive disease, to provide the basis for clinical treatment. HZ Methods 500 hypertensive disease patients were performed dynamic monitoring of blood pressure and UCG. Then 130 patients with left ventricular hypertrophy were compared the dynamic blood pressure, age, sex and diseases course with 130 patients who had not left ventricular hypertrophy. Results (1) Systolic pressure, the load and the night descent rate of systolic pressure were significantly related to left ventricular hypertrophy, there was obviously difference in two groups. To the patients with systolic pressure and diastolic pressure were all increased, the incidence rate of left ventricular hypertrophy was reduced. (2) The age of left ventricular hypertrophy group was higher than no left ventricular hypertrophy group. (3) The female's incidence rate of hypertensive disease in left ventricular hypertrophy group was higher than no left ventricular hypertrophy group. (4) The course of diseases in left ventricular hypertrophy group was extended than no left ventricular hypertrophy group. The incidence rate of left ventricular hypertrophy was obviously higher in the patients whose blood pressure was increased in the daytime. Conclusion (1) The pulse pressure is a important forecast factor in numerous risk factor. (2) The advanced age is a risk factor to hypertensive disease. (3) The female hypertensive disease patients take place left ventricular hypertrophy is easier than the male. (4) Left ventricular hypertrophy is significantly related to hypertensive disease course, and isn't significantly related to blood pressure's durative. The clinic must think highly of observing and evaluating the pulse pressure, the long disease course of old female patients. There is important clinical significance to reinforce monitoring the risk factor of left ventricular hypertrophy, and to perform pertinent treatment and prevention for the high risk patients.

Objective To evaluate the therapeutic effect of ureteroscopy with holmium laser on ureteral stricture associated with calculi.Methods The clinical data of 36 cases of ureteral stricture associated with calculi undergoing ureteroscopy with holmium laser treatment were analyzed retrospectively with 26 cases of male patients and 10 cases of female patients.The age was 26-65 years.There were upper and middle ureteral stricture associated with calculi in 8 cases,and lower segment of ureteral stricture associated with calculi in 28 cases.All the patients were treated with ureteroscopy with holmium laser.All cases were followed up for 6-12 months.In the follow-up of 36 cases B ultrasound and urinary tract flat piece or intravenous urinary tract imaging were performed to evaluate the therapeutic effect.Results Thirty-six patients underwent ureteroscopy with holmium laser successfully.No conversion to open surgery occurred.Mean operating time was 30 (20-45) min.Mean hospital stay postoperatively was 3-5 d.Postoperative 8 cases with low thermal,alleviated by the anti-infection treatment,no ureteral avulsion,leakage and severe complications such as hemorrhage.Postoperative follow-up,32 cases (89％,32/36) were cured and 4 cases (11％,4/36) were improved.Conclusion Ureteroscopy with holmium laser in treatment of ureteral stricture associated with calculi is a simple and effective minimally invasive method.

Objective To investigate the efficacy and safety of oxcarbazepine combined with levetirac-etam on children with epilepsy. Methods According to different treatments, 62 cases of children with epilepsy were divided into the OXC group (treated with oxcarbazepine, 40 cases) and the OXC combined with LEV group (treated with oxcarbazepine and levetiracetam, 20 cases). Then the therapeutic efficacy, EEG changes and ad-verse reactions of patients in the two groups were studied. Results The total efficacy was 87.5% in the OXC group, and was 95.5% of the OXC combined with LEV group, with no significant difference. EEG improvement rate was 52.5% in the OXC group and 81.8% in the OXC combined with LEV group , with significant difference (P < 0.05). The rate of adverse reactions in the OXC combined with LEV group was lower than that in the OXC group (P < 0.05). Conclusion Both levetiracetam and oxcarbazepine has good curative effect on children with epilepsy , but combination with levetiracetam can significantly decrease the epileptic discharges on EEG , with higher security.

Methods 97 cases with HD were included in this study.The morphological and numeral change of the neuron and ganglion cell of the lesions was observed and compared with the normal controls.NSE and S-100 protein immunohistochemical markers were performed in 21 cases.Result The number of the neuron and ganglion cell of allied HD was statistically significantly higher than those in the normal control or HD group (P

To investigate the effects of different surface conditioning methods on the shear bonding strength of glass-infiltrated ceramic to dentine, 24 glass-infiltrated ceramic testing-pieces were divided into four groups randomly. Among them 3 groups were treated with A(sandblasting+silance), B(etching+silace) or C(silance), separately, while group D was set as the control. Bonding the ceramic pieces to dentine with Super-Bond and the shear bonding strengths was measured. The results showed that the shear bonding strength of group D was lower than that of group A, B and C (P0.05). It is suggested that surface conditioning using combined sandblasting with silance can remarkbly improve the shear bonding strength of glass-infiltrated ceramic to dentine.

Objective To investigate the expression and characteristics distribution of ciliary neurotrophic factor (CNTF) and its receptor during the development of retina of healthy Sprague-Dawley(SD)and Royal College of Surgeons (RCS) rats with hereditary retinal degeneration. Methods The expression and distribution of ciliary neurotrophic factor and its receptor were detected by immunohistochemical staining in the retinal paraffin sections of SD and RCS rats from newborn to 12 moths old. Results In the normal retina of SD rats 0-7 days after birth, positive CNTF staining was found in all of the retinal layers and the staining of ganglion cells strengthened and other cells weakened as the age of rats increased; the staining of ganglion cells reached the peak at the 4th week and lasted till the agedness. The same results of the CNTF staining were also found in RCS rats retina. Weak positive staining of CNTFR in all of the retinal layers was seen in the 0-3-day-old SD rats; the ganglion cells were darkly stained and incontinuous positive staining at the site which would develop to be the external segment was found; as the age increased, the positive staining of external segment of photoreceptor enhanced and reached the peak at the 14-28th day after birth. At the 56th day, the staining of ganglion cells in retina of SD rats was strengthened while the staining of external segment weakened till the agedness. The expression of CNTFR in retina of 3-14-day-old RCS rats was the same as which of normal SD rats basically, but the staining of external segment weakened obviously from the 21st day on, and negative staining of external and positive ganglion cells were detected at the 28th day till the agedness. Conclusions Expression of CNTF in normal SD rats and RCS rats with hereditary retinal degeneration is almost the same. The presence of significant difference of expression of CNTFR between normal SD rats retina and RCS rats retina may provide the experimental gist for the CNTF treatment to retinal degeneration.
