Objective To observe the curative effect of fresh amniotic membrane and biotic amniotic membrane grafting for treating eye burn in early stage. Method We collected 19 cases (19eyes) with burn in ocular surface treated in our hospital from January 2006 to March 2007. The 19 cases were divided into two groups. One group was treated with amniotic membrane grafting (FAMG) and the other group was treated with biotic amniotic membrane grafting(BAMG) ,with follow time of 3 ～ 18 month after operation. Results After opera-tion, all the grafted membranes in the 19 cases survived. The corneal epithelium was well healed without rejection and secondary infection. No symblepharon or corneal neovascularization was noted and the vision improved with different degree. Conclusion Both fresh amniotic membrane and biotic amniotic membrane are used for recovering the ocular surface to cure bye burn and biotic amniotic membrane has the same curative effect as compared with fresh amniotic membrane.

Glucose-6-Phosphatase (G6Pase) was regarded as a marker enzyme of the endoplasmic reticulum in a number of different cells. The purpose of this report is to study the localization of G6Pase activity in the rat left ventricular myocardial cells. G6Pase activity was found in the lumen of the nuclear envelope, the sarcoplasmic reticulum(SR) and the subsarcolemmal cisterns. The SR tubules between the adjacent myofibrils displayed characteristic distribution on their longitudinal profiles, as a curtain-like network, the tubules appeared to be tight network facing A-band, whereas tubules formed large polygonal meshes facing I-band. It is thought that the SR tubules facing A- and I-bands, respectively, represented an adaptation of SR to the selective shortening of the myofibrils at the I-band during contraction.

Left ventricular myocardial hypertrophy was produced in the rats by ligation of the abdominal aorta below the diaphragm for seven weeks.Ultrastructurally, it was observed that the nucleus and nucleolus were enlarged, and the density of the chromatin of the hypertrophied myocardial cells was decreased. Free ribosomes and endoplasmic reticulum were increased. Golgi apparatus was well developed and was increased in number.Cytochemically, G6Pase activity was localized in the lumen of the sarcoplasmic reticulum, nuclear envelope and subsarcolemmal cisterns, and it was also positive in the regenerative rough endoplasmic reticulum. TPPase activity appeared in the Golgi apparatus, and it was especially prominent in the Golgi apparatus of the hypertrophied cells.These findings suggest that the protein synthetic activity was increased in the hypertrophied myocardial cells.

To investigate the therapeutic effect of high-dosage gamma-aminobutyric acid (GABA) on acute tetramine (TET) poisoning, 50 Kunming mice were divided into 5 groups at random and the antidotal effects of GABA or sodium dimercaptopropane sulfonate (Na-DMPS) on poisoned mice in different groups were observed in order to compare the therapeutic effects of high-dosage GABA with those of Na-DMPS. Slices of brain tissue of the poisoned mice were made to examine pathological changes of cells. The survival analysis was employed. Our results showed that both high-dosage GABA and Na-DMPS could obviously prolong the survival time, delay onset of convulsion and muscular twitch, and ameliorate the symptoms after acute tetramine poisoning in the mice. Better effects could be achieved with earlier use of high dosage GABA or Na-DMPS. There was no significant difference in prolonging the survival time between high-dose GABA and Na-DMPS used immediately after poisioning. It is concluded that high-dosage GABA can effectively antagonize acute toxicity of teramine in mice. And it is suggested that high-dosage GABA may be used as an excellent antidote for acute TET poisoning in clinical practice. The indications and correct dosage for clinical use awaits to be further studied.

Objective To investigate the clinical effects and significance of different-dose atorvastatin on soluble CD105(sCD105),high sensitive-C reactive protein(hs-CRP)and the parameters of heart rate turbulence in patients with acute coronary syndrome(ACS). Methods One hundred and six ACS patients were divided into three groups by random digits table: control group(30 patients, routine treatment),treatment group Ⅰ(38 patients, routine treatment + atorvastatin 20 mg), and treatment group Ⅱ(38patients, routine treatment + atorvastatin 40 mg). All patients were treated for 4 weeks. The levels of serum sCD105,hs-CRP,and the parameters of heart rate turbulence before and after treatment. Results Before treatment, the levels of turbulence onset(TO), turbulence slope(TS),sCD105 and hs-CRP in three groups had no significant difference(P ＞ 0.05). After treatment, TO,sCD105 and hs-CRP decreased significantly,and TS increased significantly(P＜ 0.05 or ＜ 0.01). The change amplitude of treatment group Ⅱ was the most obvious, and the levels of above mentioned index showed significantly difference compared with that of treatment group Ⅰ[TO:(0.22 ±0.18)% vs.(0.66 ± 0.23)%;TS:(6.22 ±0.83)ms/RR interval(RRI)vs.(3.90 ±0.73)ms/RRI;sCD105:(1.65 ±0.43)mg/L vs.(2.92 ±0.50)mg/L;hs-CRP:(1.68 ±0.55)mg/L vs.(2.08±0.61)mg/L](P ＜0.01). Correlation analysis showed the levels of sCD105 and hs-CRP had significantly positive correlation with TO(P ＜ 0.01)and had negative correlation with TS(P ＜ 0.01).Conclusions The atorvastatin treatment in patients with ACS may stabilize coronary vascular endothelial cells and atherosclerotic plaque, and improve autonomic nerve function. Larger doses of atorvastatin may get more benefit.

In present study, animal model of cardiac hypertrophy induced by abdominal aortic stenosis was utilized, and the lysosomes were investigated by electron microscopy and ultrastructural cytochemistry. The results showed that while cardiac hypertrophy developed, lysosomes participate in apparent remolding of cardiac muscle cells; in the late stage of cardiac hypertrophy, a great deal of autophagocytoses were viewed in some muscle cells which may result in irreversible cell damage.

The biochemical study of the nutritional status of 101 healthy pregnant women and cord blood samples showed that maternal serum protein, albumin, hemoglobin (Hb), iron (Fe), zinc (Zn) and calcium (Ca) were decreased, and serum transferrin and copper (Cu) were increased in the course of gestation.Correlation coefficients and stepwise regression analysis suggested that the concentrations of serum protein, Fe, Zn, Ca,Hb were positively correlated with the intake of calories, proteins, animal foods (especially fish and meats), Ca and vitamin C.The concentration of cord blood Ca,Zn and Fe were found highly related to the maternal serum levels in the late stage of pregnancy (P

Eight parameters about iron nutrition were observed longitudinally in eighty pregnant women from the first trimester to delivery. Their nutrients intake were recorded at the same time. It was noted that serum iron store (ferritin) decreased markedly in the course of pregnancy and the incidence of iron deficiency increased. Total iron intake was closely related to the variation of these parameters, the degree of iron deficiency in pregnant women and the content of cord ferritin. Iron in maternal serum is correlated to ferritin in the cord blood. It suggested that natural food abundant in iron, or food fortified with iron should be taken in early pregnancy to prevent iron deficiency of mothers.

Objective To propose a new observation procedure of blood pressure after the surgery of fiducial implantation for cyber knife, using the statistical analysis of the measurements of blood pressure at different time after the surgery. Methods By taking 200 patients after the surgery of fiducial implantation, the usual blood pressures and the blood pressures at different time after the surgery were compared statistically. Results Based on the statistical analysis, the usual blood pressures were statistically different from the blood pressure immediately after surgery, as well as the blood pressure at 0.5 hours after surgery [ systolic pressure (131.60 ±16.86), (129.08 ±14.77) mmHg (1 mmHg=0.133 kPa) vs. (123.00 ±11.80) mmHg, t=2.897 and 2.308, P<0.01 or 0.05;diastolic pressure (83.49±10.01), (81.75±8.99) mmHg vs. (78.22±7.59) mmHg, t=2.901 and 2.066, P<0.01 or 0.05]. The blood pressures measured at the other time after surgeries were not statistically different from the usual blood pressures, P>0.05. Conclusions Measuring the blood pressures at the time of 0, 0.5, 3.5 hours after the surgery can not only assure the complete recovery of the patients after the surgery, but also greatly reduce the work of nurses.
