The effect of TRH on endotoxic shock in rats was studied, iv 0. 22-2 mg ?kg-1 TRH significantly reversed hypotension induced by iv coli E. endotoxin (40 mg ?kg-1) into rats and caused a 4. 2 kPa rise in mean arterial pressure (MAP). MAP after TRH administered could be stablized over a higher level than control for 30 min and maintained for 3 h during observation. Interestingly enough, the MAP rose gradually in TRH-treated rats as contrast with increasingly falling of that in control group during the late shock. TRH also improved 24 h sur-vival of shock rats. The dose-response relationship could be observed between 0. 22 ~0. 67 mg ?kg-1 TRH and disappeared over a highest dose (2 mg ?kg-1). It was shown that the best dose to reverse hypotension and to improve survival was 0. 67 mg ?kg-1 TRH. Naloxone 2 mg ?kg-1 showed the nearly same effect as 0. 22 mg ?kg-1 TRH in increasing MAP, but the former had higher 24 h survival of rats than the later.

Objective To study the efficacy of laparoscopic ligation and resection for the treatment of interstitial tubal pregnancy.Methods Totally 32 patients with interstitial tubal pregnancy were enrolled into this study.The cases were randomly divided into groups A and B(16 in each).Laparoscopic ligation and resection was performed in group A,while the patients in group B received traditional salpingectomy to remove the embryo after local electrical coagulation.The operation time,intraoperative blood loss,rates of conversion to open surgery and postoperative complications,the 24-hour change of ?-hCG,and the recovery time of ?-hCG level were compared between the two groups.Results Compared to the group B,group A had significantly shorter operation time and less blood loss (40?16)min vs(60?19)min,t=-3.178,P=0.004;and(40?12)ml vs(95?26)ml,t=-7.644,P=0.000].The 24-hour change and recovery time of the level of ?-hCG were similar between the two groups (9889?7945)mIU/ml vs(9696?7883)mIU/ml,t=0.068,P=0.946;(10.1?3.2)d vs(9.8?2.4)d,t=0.294,P=0.771].Conclusions Laparoscopic ligation and resection is effective for the treatment of interstitial tubal pregnancy.

Objeictivie To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibody, anti-cyclic citrullinated peptide (anti-CCP) antibodies and glucose-6-phospha-teisomerase (GP1) for rheumatoid arthritis (RA). Methods Anti-MCV antibody, GPI and anti-CCP antibody were detected in serum samples of 109 RA patients, 24 non-RA rheumatic diseases patients and 19 healthy blood donors. The sensitivity and specificity of these parameters for the diagnosis of RA were analyzed. Results Both the positive rate and average cut off concentration of anti-MCV and GPI in RA were higher than those of non-RA rheumatic diseases or healthy controls (P<0.05). A significant difference was found between anti-MCV and GPI in RA patients. The most sensitive and specific parameter in RA was anti-MCV (99.1%) and anti-CCP (90.7%) respectively, but, when anti-MCV combined with anti-CCP, or GPI or anti-CCP and GPI, the specificity could be up to 98.1%. Coniclusions Anti-MCV, anti-CCP and GPI alone or in combination may be valuable parameters for the diagnosis of RA.

Objective:To review the drug absorption evaluation methods for pulmonary delivery. Methods: The drug absorption cell models, in vitro pulmonary membrane model and in vivo animal model were systematically summarized, and the advantages and disadvantages of those models and applications were reviewed by referring to the databases in CNKI and Pubmed. Results:The appro-priate animal model and method for the study of pulmonary absorption should be chosen according to the experimental purpose and char-acteristics of drugs. Conclusion:The review provides the thoughts and theoretical basis for the research and development of pulmonary delivery.

Objective To observe the effect of WeChat -based health education on young patients with initial treatment of pulmonary tuberculosis(TB).Methods A total of 180 TB patients were randomly divided into control group and observation group,90 cases in each group.All patients received health education for six months under the guidance of specialist nurses and physicians,but WeChat-based health education for the observation group and telephone health education for control group.Patients of the two groups were evaluated with TB cognitive level and compliance at 6 months after discharge.Results The pulmonary tuberculosis knowledge level of the observer group was significantly higher than that of the control group (89.8%vs 73.3%),the difference was statistically significant (χ2 =11.07,P<0.01);And after 6 months of follow-up,in the observation group,the compliances of patients taking medicine on time(97.8%vs 80.0%,χ2 =15.59,P<0.01),reasonable diet(95.5%vs 81.1%,χ2 =23.24, P<0.01),moderate exercise(97.8%vs 83.4%,χ2 =36.51,P<0.01) and timely referral(96.7% vs 82.2%,χ2 =20.63,P<0.01) were higher than those in the control group,the differences were statistically significant (all P<0.01).Conclusion WeChat -based health education is effective for improving TB cognitive level and the compliance of the patients.Since WeChat has been widely used,WeChat-based health education can be promoted.

We studied the influence of electrode array parameters on temperature distribution to the retina during the use of retinal prosthesis in order to avoid thermal damage to retina caused by long-term electrical stimulation. Based on real epiretinal prosthesis, a three-dimensional model of electrical stimulation for retina with 4 X 4 microelectrode array had been established using the finite element software (COMSOL Multiphysics). The steady-state temperature field of electrical stimulation of the retina was calculated, and the effects of the electrode parameters such as the distance between the electrode contacts, the materials and area of the electrode contact on temperature field were considered. The maximum increase in the retina steady temperature was about 0. 004 degrees C with practical stimulation current. When the distance between the electrode contacts was changed from 130 microm to 520 microm, the temperature was reduced by about 0.006 microC. When the contact radius was doubled from 130 microm to 260 microm, the temperature decrease was about 0.005 degrees C. It was shown that there were little temperature changes in the retina with a 4 x 4 epiretinal microelectrode array, reflecting the safety of electrical stimulation. It was also shown that the maximum temperature in the retina decreased with increasing the distance between the electrode contacts, as well as increasing the area of electrode contact. However, the change of the maximum temperature was very small when the distance became larger than the diameter of electrode contact. There was no significant difference in the effects of temperature increase among the different electrode materials. Rational selection of the distance between the electrode contacts and their area in electrode design can reduce the temperature rise induced by electrical stimulation.
