The diameters of parietal cells were measured. The results showed that the mucosal cells were successfully isolated, and it was confirmed that the parietal cells were the biggest cells among all the mucosal cells.

Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P

Objective To study the characteristics of calcific valvular heart disease (CVHD) with the aid of echocardiography. Methods Nine thousand and seventeen patients over 50 year-old who had received transthoracic echocardiographic examination were enrolled in the study. Diagnosis of CVHD was made with 2 dimension, M-mode and color Doppler echocardiography. General state of health, clinical manifestation and history of CVHD patients were also analyzed. Results Five hundred and seventy-four cases of CVHD were diagnosed and the characteristics of CVHD were observed. The diagnostic rate increased as the age increased. There was no significant difference between male and female. The calcified regions were commoner in aortic valves than in mitral valves, more frequent in non-coronary valves than in right or left coronary valves, and more frequently seen at tips of aortic valves and annuli of mitral valves than in other parts. The size of calcific plaques was usually between 3 and 10mm. Hemodynamic changes could be found in some patients. History of hypertension, coronary artery disease, and arteriosclerosis of the aorta were often found in these patients. Conclusions Echocardiography can be used to evaluate the position of calcification, size of calcification area, and degree of valvular stenosis or insufficiency, thus offers useful information for early diagnosis and treatment, and prognosis of CVHD in clinic.

Objective To explore the incidence and predisposing factors of coronary heart disease (CHD) among the patients with different types and extent of calcified valvular heart disease (CVHD). Methods 574 patients with CVHD diagnosed by echocardiography were divided into mild and severe groups based on the hemodynamic changes. The differences of incidence and predisposing factors of coronary heart disease between the two groups were compared. Results Ninety-seven cases of CVHD were categorized as having severe lesion, including aortic stenosis subgroup (AS group), aortic insufficiency subgroup (AI group) and mitral valve subgroup (MV group). All other patients were having mild lesions. There was no significant difference in blood pressure, blood lipid, fasting blood glucose, age and incidence of CAD, incidences in hypertension, hyperlipidemia and diabetes mellitus between two groups. Conclusions Mild CVHD showed similar prognostic value as that of severe CVHD, therefore it should not be ignored.

Objectives To determine the significance of serum total bile acid (TBA) in the diagnosis and treatment of infantile hepatitis syndrome. Methods Serum TBA and other liver function related items were determined with automatic enzymatic assay techniques in 67 with infantile hepatitis syndrome patients (age 26 days～7 months) and 100 normal infants (age 20 days～1 year). Results In the control group, the serum TAB level was 0～11.3 ?mol/L. TBA level was abnormal in 89.5% patients and the values were 0.5～226.0 ?mol/L ?s =(79 5?54.3) ?mol/L]. The difference was significant between the two groups. The TBA levels were well related to those of ALP, DBIL and ? GT and TBA was better than others in sensitivity and specificity. . The difference was significant between the two groups. The TBA levels were well related to those of ALP, DBIL and ? GT and TBA was better than others in sensitivity and specificity. Conclusion Serum TBA level is important in evaluating the diagnosis, treatment, and prognosis of infantile hepatitis syndrome.

Objective To reveal the hepatitis A vaccine (HepA) coverage among pre-school children in Shandong province before Hepatitis A vaccine was introduced to the EPI and to provide evidence for improving the strategy for hepatitis A control.Methods A cross-section survey was conducted among children aged between 2 and 6 years old in Shandong province in March 2008.The study population was selected by random sampling method and HepA immunization history was obtained by immunization record or recall.Results 78.90% had received one dose of HepA at least.The coverage rate decreased with age and the differences in three age groups were statistically significant (x 2 =11.54,P=0.02).The coverage rates among the boys and girls were 77.67% and 80.30% respectively,the difference was not significantly(x 2 =1.17,P=0.28).The HepA coverage rates among the children living in the eastern areas and in the richer areas were higher than the centrale and western areas and poverty areas,the difference has statistic significance (x 2 =27.25,58.17,P

Objective To study the effect of poly- DL- lactic acid (PDLLA) absorbable membrane on preventing adhesion after repair of peripheral nerve injury. Methods 60 SD rats were divided into 2 groups randomly: the suturing+ PDLLA group (experimental group) and the purely suturing group (contrast group), with 30 rats in each group. Their sciatic nerves were cut off and then sutured microsurgically. In the experimental group, the anastomotic stoma was encapsulated with PDLLA membrane; in the contrast group, there was no such a treatment. We conducted gross observations and histological examinations at 2, 4, 8, 12, and 16 weeks after operation, neural electrophysiological examinations at 12 and 16 weeks after operation, and image analysis by computer at 16 weeks after operation. Results The scar proliferation and adhesion near the anastomotic stoma in the experimental group were less extensive than those in the contrast group; regenerative nerve fibers grew more straight and orderly manner. Electrophysiological examinations and image analyses by computer also showed that the experimental group achieved better results than the contrast group. Conclusion Poly- DL- lactic acid (PDLLA) absorbable membrane can prevent scar proliferation and adhesion after repair of peripheral nerve and promote nerve functional recovery effectively.
