Aim To investigate the effects of CP1 54526,a corticotropin releasing hormone (CRH) receptor 1 antagonist,on the hippocampal neuron ap-optosis.Methods Rat hippocampal neurons were primarily cultured.Cell viability was estimated using MTT assays.Neurons were randomly divided into four groups:Normal cultures (Control);CRH-exposed cul-tures (CRH);CRH and CP1 54526 co-exposed cul-tures (CRH + CP ); CP1 54526-exposed cultures (CP).Cell apoptosis was examined by TUNEL or flow cytometry Annexin Ⅴ-PI staining.The protein levels of Bax,Bcl-2 and Caspase-3 were investigated by West-ern Blotting.Results 1 0 -8 mol·L -1 CRH decreased cell viability of cultured hippocampal neuron (P <0.05),while 50 mmol ·L -1 CP1 54526 significantly increased neuron viability (P <0.05).Compared with Control group,cell apoptotic rate,the ratio of Bax and Bcl-2 and the protein level of Caspase-3 were elevated in hippocampal neuron induced by CRH.Combined with CP1 54526 reversed the effects of CRH.Applica-tion of CP1 54526 alone had no obvious effects on cell apoptosis.Conclusions A certain concentration of CRH can induce hippocampal neuron apoptosis,and its receptor 1 antagonist CP1 54526 can effectively re-duce the apoptosis and play a neuroprotective role.

Objective To establish and evaluate a rat model presenting symptoms of arthritis-hypertension disease (AHD).Methods A total of forty healthy 5-6 week-old male SD rats were used in this study.Hypertension was induced by constriction of the left renal artery by two kidney one clip (2K1C) with a 0.25 mm silver clamp, and AHD model was established by injecting 0.1 mL complete Freund adjuvant to the left hind paw.Tail artery pressure was measured with a non-invasive blood pressure measurement system.The degree of swelling in the non-inflammatory joint of rats was measured with a paw volume measuring instrument, the arthritis index and incidence of inflammation were evaluated.The rats were sacrificed on the 35th day.The thoracic aorta, ankle joint and spleen tissues were examined by pathology using HE staining.Results The joint of AHD model rat was significantly swollen, extensive synovial cell hyperplasia, inflammatory cell infiltration, vascular pannus formation, and bone and cartilage destruction.The number of germinal centers in spleen was increased, and a large number of lymphocyte infiltration, diffuse proliferation of white pulp, and red pulp infiltration were present.The arthritis index, incidence of inflammation and histopathological scores of the joint and spleen were significantly higher than adjuvant arthritis (AA) rats;meanwhile, the blood pressure of AHD model rat was significantly increased, the thickness and cross-sectional area of thoracic aorta were significantly increased, while the lumen diameter was significantly reduced.The blood pressure and vascular injury were significantly increased or aggravated compared with the HT rats.Conclusions A rat model of arthritis-hypertension disease is successfully established by using complete Freund adjuvant intradermal injection to the footpad and surgery to narrow the left renal artery.

To explore an effective method with few operative complications for treating circumferential mixed hemorrhoids (CMH).Sixty three cases of CMH (Group A) were treated with limited external incision and internal ligation combined with restoration of intervenient skin and 34 cases (Group B) were treated with traditional external incision and internal ligation as control. Anal canal diameter (ACD), anal canal quiescent pressure (ACQP) and anal canal systolic pressure (ACSP) were determined before and after operation. Short term and long term therapeutic effects were also observed and compared in the two groups.Short term and long term therapeutic effects in Group A were better than those in Group B (P

Purpose To explore the CT features of renal cell carcinoma with cystic change and to compare them with pathological ifndings, so as to improve its diagnostic accuracy. Materials and Methods A retrospective study was carried out in 44 cases of renal cell carcinoma with cystic change conifrmed surgically and pathologically, among which 10 were multilocular cystic renal cell carcinoma, 21 were renal clear cell carcinoma and 13 were papillary renal cell carcinoma. The CT features of these 3 kinds of diseases were analyzed comparatively. Results All of 10 cases of multilocular cystic renal cell carcinoma appeared to have multilocular cysts with thin cystic walls and septa. The mean CT value of cyst was (15.8±5.6) HU. The diameter of wall nodule was larger than 5 mm in 4 cases. The contrast-enhanced CT scan showed that the cystic walls and septa had early moderate enhancement in 8 cases. Among 21 cases of renal clear cell carcinoma, 9 presented to have multilocular cysts with thick cystic walls and septa. The mean CT value of cyst was (32.5±6.7) HU. The diameter of wall nodule was larger than 5 mm in 19 cases. The cystic walls and septa had obvious early enhancement in 20 cases. As to the 13 cases of papillary renal cell carcinoma, 4 appeared to have multilocular cysts with thick cystic walls and septa. The mean CT value of cyst was (26.1±5.6) HU. The diameter of wall nodule was larger than 5mm in 12 cases, and 12 cases appeared to have slight to moderate delayed enhancement. Conclusion The CT features of renal cell carcinoma with cystic change could be used in differential diagnosis, such as with or without pseudocapsule, mean CT value of cyst, thickness of cystic wall and septum, size, boundary, and enhancement of nodule.

Objective To report the clinical results of the treatment of subtrochanteric fractures of the femur with reconstruction intramedullary nails. Methods 51 cases of femoral subtrochanteric fractures were treated with reconstruction intramedullary nails in our department in the period from January 1997 to June 2003. Among them 9 cases belonged to Russell Taylor type ⅠA, 26 ⅠB, 2 ⅡA, and 14 ⅡB. 34 patients sustained high energy injury, and 17 low energy one. 17 cases had some complicated injuries. 5 cases were open fractures. Results The mean follow up of 18.5 (3 36) months revealed that fractures healed in all the 51 cases. The clinical healing time of the fracture averaged 13.5 (8 26) weeks after surgery. The functional evaluation was done by Sanders traumatic hip rating scale. The good and excellent rate was 94.11%(48/51). Three elderly patients experienced hip pain after surgery. There were no infection,varus deformity and implant breakage. Conclusion The Russell Taylor reconstruction intramedullary nail can be used to treat all kinds of femoral subtrochanteric factures with good results, high union rate and rare complications.

Developmental changes in children can affect drug disposition and clinical effects. A physiologically-based pharmacokinetic (PBPK) model is a mathematical model that can be used to predict blood drug concentrations in children and gain insight into age-dependent physiological differences in drug disposition impact. Pediatric PBPK (P-PBPK) models have attracted attention over the past decade. With the concerted efforts of academia, pharmaceutical companies, and regulatory agencies, there are more and more examples of pediatric clinical studies using PBPK models. Nevertheless, the number of P-PBPK models and their predictive performance still lag behind adult models. By referring to the literature, we study the process of children adapting to adult absorption, distribution, metabolism, and excretion (ADME) parameters and analyze the general principles of P-PBPK model establishment. In addition, we summarize the functions and application examples of commonly used P-PBPK modeling software to provide a basis for the rational application of modeling software.

In this paper, an analysis was made on the varieties and standards of labiatae medicinal plants used in Tibetan medicine. The results showed 71 species of labiatae plants in 21 genera (including varieties) recorded in relevant literatures, involving 44 varieties of medicinal materials. Specifically, seven species (9.9%) were intersected with traditional Chinese medicines (TCM), 19 varieties (43%) were recorded in Chinese medicinal material standards at all levels, and 27 species (38%) were source plants. In Tibetan medicine standards and literatures, there are great differences between Tibetan names and translated Chinese names and among varieties of source plants. Apart from a few of varieties intersected with traditional Chinese medicines had complete standards and regulations in Chinese Pharmacopoeia, most of species only had characters, microscopic, physical and chemical identifications in Standards Issued by Ministry of Health-Tibetan Medicine, Tibetan Medicine Standard and local standards. Therefore, the Tibetan medicinal material variety-source specification and quality standard system shall be promoted on the basis of literatures research, investigations for resources and current applications and modern pharmaceutical studies.
