International Eye Science 2006;6(5):984-987
AIM: To study the antiproliferation of vitamin E succinate (VES) on pterygium fibroblasts in vitro and to find a potential agent for prevention and treatment of primary and recurrence pterygium.METHODS: Primary culture and subculture of pterygium fibroblasts were established in vitro ,and different concentrations of VES (0, 10 and 20mg/L) were added to subcultured fibroblasts, respectively. Influence of VES on the growth curve of fibroblast was observed at day 2, 4 and 7 after treatment of VES. 3- [4,5-Dimethylthiazolzyl]-2,5-Diphenyl Tetrazolium Bromide (MTT) assay at 490nm was used to evaluate the effect of the cells proliferation.RESULTS: The addition of VES to culture caused the marked descent of growth curve in comparison with the control group, and the inhibiting rate of 10 and 20mg/L of VES was 33.2% and 46.7%, 67.9%, and 76.8%, 81.7% at day 2,4 and 7, respectively. VES could obviously inhibit the fibroblast proliferation in dose-dependent manner by MTT assay.CONCLUSION: VES can significantly inhibit the proliferation of pterygium fibroblast in vitro.

AIM: To evaluate the protective effects of mycophenolate mofetil on the kidneys of type 2 diabetic rats and discover their mechanisms. METHODS: Wistar rats were divided into three groups, such as normal control rats, diabetic rats, and diabetic rats in the treatment with mycophenolate mofetil (MMF, 15 mg?kg -1 ?d -1 ). Thirteen weeks later, urinary albumin excretory rate (UAE), creatine clearance (Ccr), blood glucose, blood insulin and blood lipid were measured, and kidney pathology was observed. Inmmunohistochemistry was used to analyze the expression of CTGF, ColI and ColⅢ. RESULTS: Mycophenolate mofetil decreased UAE, Ccr and reduced glomerular volume. The expression of CTGF and deposition of ECM decreased after diabetic rats received mycophenolate mofetil. CONCLUSION: Mycophenolate mofetil can protect the kidney of diabetic rats. Its mechanism may be related to the decrease of CTGF expression and extracellular matrix deposition in renal tissue.

OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).
METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.
RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.
CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

Object: To investigate the effects of Huaiqihuang Granule, a compound Chinese herbal medicine, on expressions of nephrin and podocin of slit diaphragm of glomerular podocytes in rats with adriamycin-induced nephrosis and to explore the mechanism in reducing the proteinuria. Methods: Twenty SD rats were randomly divided into five groups: control group, model group, glucocorticoid group, Huaiqihuang Granule group and Huaiqihuang Granule plus glucocorticoid group. The 24-hour urine was collected 7, 14, 21 and 28 days after adriamycin injection respectively to measure 24-hour urinary protein, and all rats were sacrificed after 28-day treatment. Pathological changes in renal tissues were observed under a light microscope and an electron microscope. Expressions of nephrin and podocin mRNAs in renal cortex were determined by real-time polymerase chain reaction, and protein levels of nephrin and podocin were detected by Western blotting. Results: (1) In the model group and the treatment groups, the level of urinary protein increased significantly from the 14th day. (2) Under the light microscope, inflammatory cells and slight fibroplasia were found in renal interstitium of the model group, but there were less inflammatory cells in renal interstitium in the intervention groups than in the model group. Under the electron microscope, 29 days after adriamycin injection, extensive fusion of foot processes was observed. (3) The expressions of nephrin and podocin were higher in treatment groups than in the model group. (4) Proteinuria level was negatively correlated with the expressions of nephrin mRNA and nephrin and podocin proteins. Conclusion: The above results indicate that Huaiqihuang Granule can maintain the integrity of the slid diaphragram in podocyte, alleviate the lesion of glomerular filtration membrane, and decrease the proteinuria by up-regulating the expressions of nephrin and podocin. Huaiqihuang Granule plus glucocorticoid maybe has better effects than glucocorticoid alone.
