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.

OBJECTIVE: To investigate the epidemiological features in patients with allergic rhinitis (AR) in Yichang city, and put forward effective prevention and control measures. METHOD: Collecting the data of allergic rhinitis in city proper from 2010 to 2013, input the data into the database and used statistical analysis. RESULT: In recent years, the AR patients in this area increased year by year. The spring and the winter were the peak season of onset. The patients was constituted by young men. There was statistically significant difference between the age, the area,and the gender (P < 0.01). The history of allergy and the diseases related to the gender composition had statistical significance difference (P < 0.05). The allergens and the positive degree in gender, age structure had statistically significant difference (P < 0.01). CONCLUSION Need to conduct the healthy propaganda and education, optimizing the environment, change the bad habits, timely medical treatment, standard treatment.

Objective To provide ideal endometriosis animal models for research new treatment methods. Methods 64 Sexual mature without pregnant SD rats who has regular oestrous cycle were underwent operation that autologous endometrium were transplanted to peritoneum and subcutaneous with lancet gently cut tissue of where to transplant in the rut, and compared the model of peritoneum and subcutaneous after 4 weeks.Results The general success rate of autologous endometrium transplantation in rat estrus was 93.3%,and the peritoneum transplantation success rate was 51.7%, subcutaneous was 88.3%, the difference of the two place transplantation has statistical significance. Compare the two parts of volume of endometriosis,there was no statistically significant difference.Conclusion Using the lancet to establish the endometriosis model has a high success rate, and subcutaneous model is better than peritoneum.

Objective To evaluate the effect of fingolimod(FTY720) on angiotensin Ⅱ(AngⅡ)-induced renal oxidative stress in rats and its possible mechanisms.Methods Thirty-six male Sprague-Dawley rats were divided into three groups through random number tables:AngⅡ infusion group(twelve rats,infusion of AngⅡvia subcutaneous osmotic pumps),0.9% sodium hydrochloride solution infusion group(twelve rats,infusion of equal volume of 0.9% sodium hydrochloride solution via subcutaneous osmotic pumps) and FTY720 intervention group(twelve rats,intra-gastric administration of FTY720 besides AngⅡ infusion).Urine samples were collected for 24 hours every week.Blood samples and kidneys were collected when rats were sacrificed at day 14 and 28 d respectively.MDA and T-SOD assay Kits were used to detect the concentrations of MDA and T-SOD in serum and kidney homogenates.Renal pathological changes were observed by light microscope.The expression of Nox4 in the kidneys was evaluated by immunohistochemistry.Results Compared with 0.9% sodium hydrochloride solution infusion rats of the same period,AngⅡ-infused rats developed significant proteinuria.The concentration of serum creatinine,urea nitrogen,AngⅡ and MDA were increased(P<0.05),T-SOD was significantly decreased on days 14 and 28(P<0.05),the serum albumin was significantly increased on day 28(P<0.05),while FTY720 partially reversed these changes.The renal tissue of AngⅡ-infused rats presented mesangial cells proliferation,mesangial matrix deposition,tubular epithelial cells effacement,sclerosis and atrophy in part of the glomerular.FTY720 can alleviate these changes.Immunohistochemistry showed that Nox4 was primarily located in the distal tubule.The expression of Nox4 was significantly increased in AngⅡ-infused rats as compared with that of 0.9% sodium hydrochloride solution infused group rats,and FTY720 administration prevented the change effectively.Conclusion AngⅡ-induced renal injury could be attenuated by FTY720 via preventing oxidative stress.

OBJECTIVE:To observe clinical efficacy and safety of tiotropium bromide combined with budesonide formoterol in the treatment of severe bronchial asthma in adults. METHODS:A total of 110 adult patients with severe bronchial asthma were selected from our hospital during Mar. 2013-Mar. 2016 were divided into control group and observation group according to random number table,with 55 cases in each group. Control group was given Budesonide formoterol powder for inhalation,2 inhalations each time,bid;observation group was additionally given Tiotropium bromide powder for inhalation 18 μg,qd,on the basis of con-trol group. Both groups were treated for 6 months. Clinical efficacies as well as ACT scores,respiration function indexes and the times of acute attack of asthma before and after treatment,the occurrence of ADR were compared between 2 groups. RESULTS:The efficiency rate and total response rate of observation group were 54.55% and 96.36%,which were significantly higher than 32.73%,78.18% in control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in ACT scores,respiration function indexes or the times of acute attack of asthma between 2 groups(P>0.05). After treatment,ACT scores of 2 groups were significantly higher than before treatment;FEV1,FEV1/FVC and PEF were significantly greater than be-fore treatment,PEFR was significantly lower than before treatment;and the indexes in observation group was significantly better than control group,with statistical significance(P<0.05). 1,3,6 months after treatment,the times of acute attack of asthma in 2 groups were significantly less than before treatment,and that in observation group was significantly less than control group,with statistical significance(P<0.05). The incidence of ADR in observation group was 20.00%,and there was no statistical signifi-cance compared to 14.55% of control group(P>0.05). CONCLUSIONS:Tiotropium bromide combined with budesonide formoter-ol in the treatment of severe bronchial asthma in adults can effectively relieve the severity of disease,improve respiration function, reduce the times of acute attack of asthma,and have good therapeutic efficacy and safety.
