The Rhei Radix et Rhizoma was one of the most widely used traditional Chinese medicine for its special biological activities. The content of rhein, one of its major compounds, was an important standard for the quantity control of Rhei Radix et Rhizoma. The major method used for the detection of rhein was instrumental analysis like HPLC, but it was complex, time-consuming and cannot detect large samples at the same time. The enzyme-linked imunmosorbent assay (ELISA) was accurate, reliable, simple, low costs, and of a high-throughout. Recently, it was widely used for the determination of those small molecule compounds in some traditional Chinese medicinal plants. In this study, an artificial antigen were synthesized by the carbodiimide (CDI) method. Rhein-bovine (rhein-BSA) conju gate and rhein-ovalbumin (rhein-OVA) conjugate, were produced as the immunogen and coating antigen, respectively. The conjugate and the hapten number in the conjugate were determined by UV-Vis spectrophotometry (UV). The conjugation ratio of Rhein and BSA was about 4.0:1, rhein acid and OVA was 2.6 : 1, respectively. Rhein-BSA conjugate was used to immunize Bal b/c mice to produce antiserum. The antiserum titer of the Rhein were higher than 8000 detected by ELISA. The successfully synthesized conjugate antigen rhein-BSA implies its feasibility in the establishment of fast immunoassay for the rhein content determination.

In this study, five rhesus macaques were inoculated intravenously with SIVmac251 to establish a model of simian autoimmune deficiency syndrome (SAIDS). Peripheral blood samples were collected at different time points to monitor changes in the total T cell number and T lymphocyte subset. Plasma viral loads, cytokine expression levels and anti-SIV antibody levels were also assayed to acquire certain basic indexes to evaluate disease progression in the rhesus macaque SAIDS model. During the acute stage of infection, plasma viral loads reached a peak at week 1 post-inoculation and lasted for approximately 3 to 44 weeks. The CD3+ CD4+ T lymphocyte count in peripheral blood also transitorily decreased. During the same period, the level of interferon-gamma show an increasing trend, whereas IL-12 levels decreased; IL-2, IL-4, IL-10 and TNF-alpha were maintained at normal levels or could not be detected. During the asymptomatic and ARC phases, plasma viral loads persisted above 10(4) RNA copies/mL and either increased or declined during the later stages of disease; CD3+ CD4+ counts showed a steadily declining trend and the ratio of CD4 to CD8 decreased during late-stage disease. Moreover, antibodies against viral proteins were detected in the plasma and showed a significant increasing trend, while there were no apparently changes in the levels of IFN-gamma, IL-12, IL-2, IL-4, IL-10 and TNF-alpha. In conclusion, the characteristics of the SIV animal models in our study are similar to those of patients with AIDS. Therefore, the rhesus macaque SIVmac251 infection models can be applied for further studies into AIDS.

Objectives To investigate the changes in the masseter muscle following osteotomy of the prominent mandibular angle using real-time three-dimensional (3D) ultrasonography, and to supply guidance for resection of the mandibular angle. Methods Real-time 3D ultrasonography was applied preand post-operatively (over a 6-month follow-up period) to 10 patients who underwent curved osteotomy with the following objectives: (1) to reconstruct the morphological changes of the masseter under different conditions; (2) to assess masseter muscle volume changes, and (3) to obtain the dynamic morphological changes of masseter during mouth opening and closing. Results The reconstructed 3D images revealed that longitudinal diameters of masseter muscle decreased and angle regions changed to be arc-shaped with significant thinning 6 months after operation. The mean volume of masseter muscle was (18. 222 ±3. 028) cm36 months post-operatively, compared with the pre-operation mass of (25. 480 ± 7. 113) cm3,the statistical difference was significant (P＜0.01). Transverse and longitudinal changes of the thickest masseter muscle section 6 months post-operatively were of no statistic difference (P＞0. 01) compared with pre-operation status during mouth opening and closing motions. Conclusion A certain extent of atrophy occurs primarily in the angle region of masseter muscle after mandibular angle ostectomy. However, these changes do not significantly impair masseter muscle function. Real-time 3D ultrasonography offers a novel, safe, and convenient technique for masseter muscle reconstruction and observation of masseter muscle movement.

BACKGROUND: Enophthalmos deformity is the most common complication caused by orbital blow-out fractures, and others are diplopia and worsening of visual acuity. Since the therapeutic result of orbital blow-out is not satisfactory and many complications exist after operation, it is still a dispute to select implantation materials and therapeutic regimens.OBJECTIVE: To observe the therapeutic effect and assess the improvement of visual function by surgical reconstruction with porous high-density polyethylene (Medpor) for the correction of enophthalmos deformity caused by orbital blow-out fractures.DESIGN: A pre-and postoperative controlled study.SETTING: Beauty Center for Trauma Repair,Plastic Surgery Hospital,Peking Union Medical College, Chinese Academy of Medical Science .PARTICIPANTS: Totally 56 patients with orbital blow-out fractures who had enophthalmos deformity caused by fists or traffic accidents, treated at Beauty Center for Trauma Repair,Plastic Surgery Hospital, Peking Union Medical College, Chinese Academy of Medical Science, were selected in this study from December 1996 to March 2004. Final diagnosis were made with case history, X-ray film, two-demensional and three-dimensional CT before operation. 24 cases were accompanied with other areas fractures such as zygoma and nasal bone, 34 cases with diplopia, 35 cases with visual acuity worsening after injured.METHODS: ①Material implantation: Exposure of the orbital floor, inferior and medial walls could be performed through a 2 mm inferior subciliary incision of 3 cm long. To approach the orbital rim via a dissection plane anterior to the orbital septum, sub-periosteal dissection was then performed over the orbital rim, and along the orbital floor to the orbital apex. Mobilized the soft tissue from the bone throughout the entire area of fractures and re-position it to its proper position. Took Medpor (Type 6331) sheets as the implantation materials, trimmed Medpor sheets according to the radian and anatomic form, and 2 mm larger than the defect rim was needed.If other operations were needed during the operation, they could be done.Mannitol and dexamethasone should be used just postoperatively to decrease edema of the orbital contents and reduce inner orbital excessive pressure. ②Functional evaluation standard: Diplopia: completely disappear meant recovered, less diplopia residual meant improvement, no improvement meant inefficacy. Enophthalmos: marked improvement meant the degree of enophthalmos stabilizated at below 2 mm, less improvement meant stabilizated at above 2 mm.MAIN OUTCOME MEASURES: ①Improvement of enophthalmos; ②Improvement of diplopia ; ③Improvement of visual acuity.RESULTS: ①All 56 cases of enophthalmos deformities caused by orbital blow-out fractures improved greatly. ② Of all the 34 patients with diplopia, 27 recovered. ③ 9 patients' visual acuity of 35 improved with different degrees. No diplopia or visual acuity worsening occurred. With a follow-up ranging from 2 months to 5 years, the degree of enophthalmos stabilizated at below 2 mm, and no relapse and other complications occurred.CONCLUTION: Medpor has such advantages as better histocompatibility,fewer complications and better visual function improvement, so it is the preferred implantation material for correcting enophthalmos deformity caused by orbital blow-out fractures.

To discuss the protective effect of aralosides (AS) on I/R-induced rat myocardial injury. The adult rat ventricular myocyte ischemia model was established through perfusion with sodium lactate perfusate and reperfusion with Ca(2+) -containing Tyrode's solution simulation. The cell contraction and ion concentration synchronization determination system was applied to detect the effect of AS on single I/R cell contraction and Ca2+ transients. According to the findings, AS could increase resting sarcomere length, contraction amplitude, ± dL/dt(max), calcium transient amplitude and speed of post-reperfusion myocardial cells (P < 0.05, P < 0.01), and decrease in time for achieving 90.0% of maximum relaxation, time for achieving peak value, resting calcium ratio, contraction period [Ca2+] i, time for achieving 50.0% of maximum relaxation and attenuation rate of intracellular calcium transient (P < 0.05, P < 0.01). Therefore, it is suggested that AS improved the post-reperfusion cell contraction and injury of calcium homeostasis.
