AIM:To observe the change of nitric oxide(NO)and hydrogen sulfide(H_2S)in blood and lung homogenate of hypoxic pulmonary hypertension(HPH)rat model,and to discuss the meaning of inhalation sodium nitrite and these factors in the treatment of HPH. METHODS:Fifty healthy male Wistar rats were assigned randomly into 5 groups(10 rats each):normoxia control group(NC),normoxia sodium nitrite group(NNI),hypoxic control group(HC),hypoxic normal saline group(HNS)and hypoxic sodium nitrite group(HNI). The mean pulmonary arterial pressure(mPAP),weight of right ventricle,weight of left ventricle plus septum,and the ratio of the weight of right ventricle to that of left ventricle plus septum(right ventricle hypertrophy index,RVHI)were also determined. The serum level of NO and plasma level of H_2S were measured,and at the same time the levels of NO in the lung homogenate were detected. The structures in pulmonary arteries were examined using optical microscope. RESULTS:After model established,compared to that in the normoxia groups,the body weight decreased significantly in hypoxia groups(P<0.05),although no difference of body weight in five groups before producing model was observed. Compared to that in normoxia groups,the levels of mPAP and RVHI increased significantly in hypoxia groups,and compared to that in hypoxia control groups and hypoxia normal saline group,mPAP and RVHI levels decreased significantly in hypoxia sodium nitrite group(P<0.05). Compared to that in normoxia groups,the serum level of NO decreased significantly in hypoxia groups(P<0.05). NO level in lung homogenate decreased significantly in hypoxia control group and hypoxia normal saline group as compared to that in normoxia groups(P<0.05),and no obvious difference between hypoxic sodium nitrite group and normoxia groups was found. The plasma level of H_2S was decreased significantly in hypoxia groups(P<0.05)as compared to that in normoxia groups. H_2S level increased significantly in hypoxia sodium nitrite group as compared to that in hypoxia control groups and hypoxia normal saline group(P<0.05). Observation under optical microscope,the lumen structure of lung in normoxia control group was normal. No significant change in normoxia sodium nitrite group was found. The proliferation of smooth muscle cells(SMCs),the collagen fiber deposition in the vessel wall and every caliber thickening was observed in hypoxic control group. The same changes were also observed in hypoxic normal saline group. The thickened caliber was relieved significantly in hypoxic nitrite group. CONCLUSION:Pulmonary hypertension and right ventricle reconstitution can be relieved by inhalation of sodium nitrite,and can be regulated by the level of NO and H_2S in rats. Above all,inhalation of sodium nitrite may degrade HPH directly or by affecting the externalization and synthesizing of gas signaling molecule indirectly.

OBJECTIVETo evaluate the histological changes on the femoral heads of the SANFH rabbit animal models and after it were intervened by Osteoking (herbs of the Yi minority in Yunnan province) using general and light microscope observation.

METHODA total of 150 New Zealand white rabbits were randomly divided into a non-treatment control group (A group, n = 24), normal rabbits with Osteoking treatment group (B group, n = 24), and the experimental group (n = 102). The experimental group was injected with escherichia coli endotoxin (10 microg x kg(-1)) into auricular vein twice by 24-hour intervals, and prednisolone (20 mg x kg(-1)) was injected into buttock three times by 24-hour intervals to make steroid-induced femoral head necrosis model. At the fifth week, 48 out of 53 rabbits were equally divided into model group (C group, n = 24, models with non-treatment Osteoking) and abnormal rabbits with Osteoking treatment group (D group, n = 24). B group and D group were intragastrically administrated with Osteoking, once every two days. A group and C group were intragastrically administrated with the equal volume of saline. At 8th, 12th and 16th week after model preparation, the femoral head specimens were observed under the general and a light microscope.

RESULTMacroscopic and light microscopic analysis showed that, clear bone necrosis of femoral head was observed in the C group, and a large number of fat cell proliferation was found in the bone marrow cavity. As compared with C group, the damage level of cells in D group was milder, however, the density of bone trabecula from Osteoking treatment was high, and the ratio of bone lacuna was very low. It is also demonstrated that the surface area of bone necrosis was decreased, and the number of cells from adiposities was reduced significantly. The phenomenon of bone necrosis repaired apparently. The morphology of femoral head from A group and B group is normal.

CONCLUSIONIt suggested that Osteoking could effectively help repair steroid-induced femoral head necrosis in the early stage.

Objective To investigate the clinical value of coronary artery Z-scores on echocardiography in diagnosing coronary artery abnormalities. Methods The echocardiography results of 612 patients with Kawasaki disease (KD) at the acute and recovery phase were retrospectively studied. Coronary artery luminal diameters were converted to body-surface-area-adjusted Z-scores. According to coronary Z-scores classiifcation, all the subjects were divided to four groups:415 cases with no dilation (ND), 133 cases with small coronary artery abnormalities (SCAAs), 47 cases with large coronary artery abnormalities (LCAAs), and 17 cases with giant coronary artery abnormalities (GCAAs). Clinical features (gender, age, typical clinical manifestations, fever duration) and laboratory results (CRP, ESR, WBC, PLT) were compared among all the four groups. Coronary artery diameters and the Z-scores were compared between acute and convalescence phase. Results Along with the increase of coronary Z-score, fever duration was prolonged [ND group:(7.75±3.12) d, SCAAs group (8.50±4.12) d, LCAAs group: (8.57±3.58) d, GCAAs group: (11.88±4.33) d, F=22.375, P<0.05]. With coronary Z-score increasing, PLT also increased (F=22.029, P=0.000), and the highest PLT was observed in GCAAs group. There were no significant differences in the CRP, ESR and WBC among all the four groups (F=0.236, 1.116, 0.121, all P>0.05). No significant different coronary diameters were found in ND cases between recovery and acute phase [(2.24±0.34) mm vs (2.33±0.36) mm, t=1.926, P > 0.05]. But there were significant difference in the coronary Z-scores of ND patients between recovery and acute phase (0.41±0.82 vs 1.17±0.75, t=8.332, P < 0.05). The coronary Z-scores in SCAAs group (1.32±0.89 vs 3.40±0.62, t=11.073, P < 0.05), LCAAs group (3.12±2.27 vs 6.20±1.28, t=4.579, P<0.05) and GCAAs group (11.88±6.77 vs 20.4±9.70, t=3.480, P<0.05) at recovery phase were smaller than values at acute phase. Conclusions The KD coronary Z-scores are the body-surface-area-adjusted standard value, and not subject to the influence of children growth and development. Therefore, it may accurately evaluate the severity of coronary artery abnormalities and its recovery process. Accurate quantitative of the coronary artery luminal dimensions is important in KD clinical management and prognosis prediction.
