OBJECTIVETo observe protective effects of Schisandra extract (SE) on embryotoxicity and reproductive toxicity of early pregnant rats exposed to Benzo[a]pyrene (Bap).

METHODSPregnant rat model was prepared using periodic screening cage method. Totally 50 female pregnant SD rats were divided into five groups by randomized block design according to the weight, i.e., the BaP model group, the low dose SE group, the middle dose SE group, the high dose SE group, the normal control group, 10 rats in each group. Rats in the BaP model group were administered with BaP at a daily dose of 2 mg/kg by gastrogavage. Rats in low, middle, and high dose SE groups were administered by gastrogavage with BaP (at a daily dose of 2 mg/kg) plus SE at a daily dose of 40, 200, and 1 000 mg/kg, respectively. Equal volume of olive oil was administered to rats in the normal control group by gastrogavage. All medication was performed for 8 successive days. Changes of rat body weight in each period were observed. The uterus embryonic total quality and ovary quality were measured, and organ index calculated. The number of corpus luteum, the number of embryo implantation, and the number of absorbed embryo were statistically calculated respectively. The implantation rate and the absorbed embryos rate were calculated. Serum levels of human chorionic gonadotrophin β (β-HCG) and progesterone (PROG) were detected by ELISA.

RESULTSCompared with the normal control group, the weight of 9-day pregnant rats, the number of embryo implantation, the uterus embryonic total index, ovary index, serum levels of β-HCG and PROG all decreased in the Bap model group with significant difference (P < 0.05, P < 0.01). Compared with the Bap model group, body weight, the uterus embryonic total index, and the PROG level increased in 3 dose SE groups (P < 0.05, P < 0.01). Ovary index and serum β-HCG increased in middle and high dose SE groups (P < 0.05, P < 0.01). The number of implantation obviously increased in the high dose SE groups (P < 0.01).

CONCLUSIONSE could reduce the embryotoxicity and reproductive toxicity of early pregnant rats exposed to Benzo[a]pyrene.

Objective: To investagate the antioxidative action of aloe and its dose-effect relationship. Methods:Sprague-Dawley rats were killed and then the livers were removed to isolate the microsome which can generate the reactive oxygen species in the presence of VC and Fe2+ or cumene hydroperoxite(CHP). In these peroxidative damage models, different dosages of aloe extract were added. Then the contents of malondialdehyde (MDA) were examined for analyzing the antioxidative action of aloe extract. Results:In CHP model, the content of MDA in those groups with different dosages of aloe extract decreased significantly (P

OBJECTIVE:To study the influence of calcineurin gene polymorphism on the efficacy of cyclosporine A (CsA). METHODS:The blood samples of patients treated with CsA were collected. The trough blood concentration of CsA was detected by EMIT. The genotype of PPP3CA and PPP3CB was assayed by RFLP-PCR method. The expression of NFAT-regulated gene IL-2, IFN-γand GM-CSF were measured by RT-qPCR,which were used to define the index of indirect efficacy of CsA. The relationship of gene polymorphism with CsA efficacy was study by relationship analysis and multiple factor regression method,etc. RESULTS:A to-tal of 100 blood samples were collected. There was no significant correlation between the expression of CsA efficacy-related NFAT-reg-ulated gene GM-CSF and trough concentration of CsA(rGM-CSF=-0.04,P=0.238);the expression of IL-2 and IFN-γ were negatively correlated with trough concentration of CsA significantly(rIL-2=-0.384 3,P<0.001;rIFN-γ=-0.335 4,P<0.001). Using the average value of mRNA expression of IL-2 and IFN-γas indirect efficacy index,the polymorphism of PPP3CB rs3763679 site significantly in-fluenced the efficacy of CsA(P<0.05),but PPP3CA rs3804358 had no any effect on it(P>0.05). Stratified analysis showed that among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 genovariation(TC+TT) were better than those with wild-type gene (CC)(P<0.05). After the efficacy was normalized by CsA trough concentration, multivariate analysis showed that normalized efficacy of CsA was negatively correlated with gender,PPP3CB rs3763679,lactate dehy-drogenase and creatinine significantly,but positively correlated with PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate,etc. CONCLUSIONS:PPP3CB rs3763679 gene polymorphism influence the efficacy of CsA;among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 TT+TC is better than that of CC type. At the same time,gender,PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate and other factors all can influence the nor-malized efficacy of CsA to different extent. Multiple factors should be considered when using CsA.

BACKGROUND :Although the conventional 20 G pars plana vitrectomy can improve the prognosis of vitreous-retina diseases,but it would also cause serious operation related injury and much complications.OBJECTIVE:To evaluate the practicability and safety of 25-gauge transconjunctival sutureless vitrectomy system (TSV25G) in the macular surgery, so as to elicit the preliminary clinical experience of mimimally invasive vitrectomy system.DESIGN:Case analysisSETTING: Department of Ophthalmology, General Hospital of Chinese People's Armed Police Force; Department of Ophthalmology, Beijing Sino Japen Friendship Hospital; Department of Ophthalmology and Visual Science, Chinese University of Hong Kong; Department of Ophthalmology,Prince of Wales Hospital, Hong Kong PARTICIPANTS: From July 2003 to July 2004, 16 patients with macular diseases were admitted to the Department of Ophthalmology in the General Hospital of Chinese People's Armed Police Force and taken as subjects (n=16), they were confirmed as epiretinal membrane in 9 eyes, idiopathic macular hole in 3 eyes, traumatic macular hole in 2 eyes and vitreo-macu lar tractional syndrome in 2 eyes. The course of disease ranged from 3 to 36 months with eyesight varied between 0.06 and 0.4.METHODS: 16 eyes underwent preoperative ophthalmic evaluation in cluding visual acuity measurement, Amsler chart test, slit lamp microscopy,.indirect ophthalmoscopy tonometry and optical coherence tomography (OCT). For the macular hole patients OCT was performed. 25-gauge Transconjunctival Sutureless Vitrectomy System (TSV25G) was used to carry on minimally invasive surgery under anesthesia state, the surgical parameter was set as: high speed cutter with rate of 1500 cuts per minute,BSS bottle was hang at height of 40-50 cm, the maximum aspiration of TSV25G was 550 mm Hg with the intraocular pressure remained at around 29-35 mmHg during the operation. Three-beveled trocar were used to make three-transeonjunctival incision on sclera of about 0.5 mm long respectively in the infratemporal, superotemporal, and supraotemporal quan drants, meanwhile a transconjunctival cannula was placed. One end of the infusion tube was inserted into the infratemporal cannula to establish infusion with the other two cannulas used for the intraocular operation with 25-gauge vitreous cutter and other instruments, such as vitreoectomy and membrane dislocation. The surgery was terminated by removing the cannula except for ceaseless leak, the conjunctival and scleral incision were not sutured. Patients received follow-up examination for 1-12 months postoperatively.MAIN OUTCOME MEASURES:①The operative time and the time for the establishment of three access. ② Changes of intraocular pressure after operation. ③ The effusion from the puncture after the intraocular perfor mance. ④ The postoperative vision, operative complication and the sealing of the holes.RESULTS:All of the 16 patients completed the vitrectomy; and entered the data analysis.①16 patients complete the vitrectomy with the operative time of 28-56 minutes (the mean of 37 minutes). The average time for the establishment of three access and closing was 84 s and 32 s respectively.②The average preoperative intraocular pressure was 16.4 mm Hg,comparing with 13.5,15.5,17.9 mm Hg at postoperative 1 day, 1 w and 1 m. ③Water leakage were found in 4 wounds of three patients after operation, 3 wounds were sealed after injecting 1-2 mL disinfected air into the eyes, the other one sutured with 6-0 absorbable suture. ④The mean time of inpatients were 5 days postoperatively. The visual acuity improved in 14 patients by the average of three lines, amongst which visual acuity was found improved to above 0.8 in 5 patients and the visual distortion disappeared in 8 eyes and attenuated in 3 eyes. But still there were 2 cases without improvement.No surgical complications were noted and macular hole gained clinical sealing in totally 5 eyes.CONCLUSION: TSV25G system can simplify the surgical procedure with many other advantages such as decreasing the operation related injury and complications, as well as shortening operative time, which benefits the rapid rehabilitation.
