Objective To investigate the clinical effect of high dose of calcitriol on end-stage renal disease (ESRD) in patients with secondary hyperparathyroidism (SHPT). Methods The clinical data of patients with ESRDcomplicated with SHPT were retrospectively analyzed. According to the treatment method were divided into control group and observation group, the control group were given conventional dose of calcitriol treatment, the observation group were treated with high dose of calcitriol. The differences of calcium and phosphorus levels, parathyroid hormone (PTH) level and quality of life were observed between the two groups before and after treatment. Results The serum phosphorus, calcium and calcium-phosphorus product in two groups of patients before treatment had no significant difference. After treatment, the above indicators decreased in two groups of patients compared with those before treatment, and the observation group was significantly lower (P<0.05). Before treatment, there was no difference in the levels of PTH between the two groups. After treatment, the level of PTH in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). There was no significant difference in quality of life between the two groups before treatment. After treatment, the quality of life in the two groups were higher than before treatment, and the observation group was significantly higher (P<0.05). Conclusion High dose of calcitriol has good therapeutic effect for ESRD patients with SHPT and can significantly improve the patient's calcium and phosphorus and PTH levels, improve the quality of life of patients.

Beta-Elemene is an antitumor drug which is isolated from the traditional Chinese medicinal herb Curcumae Phaeocaulis Rhizoma, it is the main component of elemene which is extracted from the plant and delivered via blood circulation after intravenous injection. The antitumor effect of beta-elemene in vitro and in vivo was definite, and beta-elemene could improve the patient immunity and no sever side effect, drug resistance or bone marrow suppression were found during the clinical studies. And human serum albumin (HSA) is a primary extracellular protein which has a high concentration distribution in blood plasma and has many characteristic physiological functions. Therefore, the binding of beta-elemene to protein may be very important for absorption, distribution, metabolism and elimination. Therefore, the study on the interaction of beta-elemene with drug-carrying protein is very important. In this work, molecular binding of beta-elemene to human serum albumin (HSA) was investigated by using spectrofluorometer. the binding constants suggested that a strong interaction and the formation of a complex between beta-elemene and HSA. This clearly implies that beta-elemene can be stored and removed by the proteins in the body. Furthermore, the fluorescence quenching results showed that the HSA fluorescence was quenched by beta-elemene through static quenching mechanism. Thermodynamic parameters showed that hydrophobic interactions play a role in the binding of beta-elemene to HSA. The negative deltaH(0) and positive deltaS(0) in case of beta-elemene therefore showed that electrostatic attraction play a role in the binding of beta-elemene to HSA.

Objective To evaluate the diagnostic value of different sequences of magnetic resonance imaging (MRI) in repaired meniscus.Methods From September 2002 to December 2008,118 patients (130 menisci) underwent arthroscopic meniscus suture in our hospital,including 94 males and 24 females,aged from 15 to 50 years (average,25.7t7.5 years).All patients underwent MRI and second-look arthroscopy postoperatively.Different sequences of MRI were taken to evaluate the grade of meniscal signal at repaired site and the slices involved by grade 3 signal.The diagnostic sensitivity,specificity,accuracy,positive predict value (PPV) and negative predict value (NPV) were calculated for each sequence by using second-look arthroscopy as the gold standard.Results The total healing rate was 80.8％ (105/130) by second-look arthroscopy,which was higher than that by different sequences of MRI.The integrated T2 sequence held the highest diagnostic value,and the sensitivity,specificity,accuracy,PPV and NPV were 76.0％,71.4％,72.3％,38.8％ and 92.6％,respectively.According to the second-look arthroscopy result,the menisci were divided into the healed group and unhealed group.In the healed group,28.6％ of cases (30/105) showed grade 3 signal in MRI,which was less than that (76.0％) in the unhealed group.The rate of the new grade 3 signal (8.6％) and the slices involved by grade 3 signal (0.8±1.0) in the healed group were less than those (16.0％ and 3.0±2.0) in the unhealed group.Conclusion The diagnostic value of the integrated T2 sequence is encouraging with high sensitivity,specificity and accuracy.The new grade 3 signal in the repaired meniscus usually implies that the meniscus is not healed.

Objective To investigate changes in the expression of prepro-orexin and orexin receptor-1 ( OX1R) following permanent middle cerebral artery occlusion ( MCAO ) with or without preconditioning through electrical stimulation of the cerebellar fastigial nucleus (FNS). Methods Wistar rats were subjected to permanent MCAO and randomly divided into 5 groups: a sham-operated control group (PO), an FNS preconditioning + shamoperated control group (FNS-PO) , an ischemia group, an FNS preconditioning + ischemia group (FNS-PI) and a cerebellar fastigial nucleus injury + FNS preconditioning + ischemia group (FNL-FNS-PI). Each group was divided into 5 subgroups according to the time at which the animals were sacrificed after the MCAO ( 1, 3, 6, 12 and 24 h).RT-PCR was used to detect expression of OX1R mRNA, and ELISA to measure the levels of orexin-A in the hypothalamus and plasma. Results The immunoreactivity of prepro-orexin decreased significantly in the PI groups, with further decreases over time. At the 12th h after MCAO, the immunoreactivity of prepro-orexin reached a minimum.There were significant differences between the rats in the PO and FNS-PO groups. On the contrary, the immunoreactivity of OX1R increased significantly in the PI groups, with further increases continuing over time, peaking at 12 h after the MCAO. There were significant differences between the PO and FNS-PO groups. In the rats with FNS preconditioning (PI-FNS) , the decrease in prepro-orexin and the increase in OX1R were significantly inhibited compared to the PI subgroups at the 6th and 12th hour. There was no significant difference between the FNL-PIFNS group and the PI group. The expression of OX1R mRNA increased significantly in the PI group, with further increases continuing over time, peaking at 24 hours. The plasma levels of orexin-A were not significantly different among the groups, but the levels of orexin-A in the hypothalamus decreased significantly in the PI and FNL-PI-FNS groups, with further decreases continuing over time. At the 12th h after the MCAO the levels were significantly different compared with the PO and PO-FNS groups. While in the rats with FNS preconditioning (PI-FNS) , the decrease in orexin-A level was reversed and there was no significant difference compared with PO and PO-FNS groups. Conclusions The orexinergic system is altered following cerebral ischaemia. FNS preconditioning may be able to regulate these changes.

Objective To study the clinical features of children with rotavirus enteritis complicated with respiratory infection.Methods The clinical features of 32 children with rotavirus enteritis were evaluated retrospectively complicated with respiratory infection (respiratory infection group) and 37 children with rotavirus enteritis complicated without parenteral infection (control group).Results 1. The respiratory symptoms became alleviative as the alimentary symptoms changed for better. 2.

Objective To evaluate the clinical value of prone flexed posture lumber CT/MRI examination for lumber disc herniation. Methods Supine posture CT/MRI (SPCT/MRI) and prone flexed posture CT/MRI (PFPCT/MRI) examinations were performed on 1200 patients with lumber disc herniation.The imaging findings on SPCT/MRI and PFPCT/MRI of each case were compared. According to the CT/MRI diagnostic criteria for encapsulated lumber disc herniation ( HLDH ), adhered lumber disc herniation (ALDH) and ruptured lumber disc herniation ( RLDH), the 1200 cases were divided into three groups. On the basis of PFPCT/MRI findings, 868 cases were selected for percutaneous lumbar diskectomy (PLD) with half to twelve years follow up. Treatment effects of PLD on HLDH, ALDH and RLDH were analyzed with x2test. Results Among 249 ALDH cases diagnosed by SPCT/MRI 35 were identified as HLDH by PFPCT/MRI. Among 163 RLDH cases diagnosed by SPCT/MRI, 9 HLDH and 17 ALDH were identified by PFPCT/MRI. In 868 cases treated with PLD, the effective rate of HLDH ( n = 832), ALDH ( n = 25 ), RLDH ( n =11 ) were 825/832 (99. 2% ), 13/25, and 1/11 respectively. The effective rate of HLDH is significantly different from that of ALDH and RLDH ( x2 = 369. 69, P ＜ 0. 01 ). Conclusion PFPCT/MRI may change the grouping result of lumber disc herniation made by SPCT/MRI and can be used to objectively select patients for PLD.
