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.

Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.

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.

OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

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.

Objective To investigate the effects of different doses of remifentanil on learning and memory ability,the expression of hippocampal tissue phosphorylation of cAMP response element binding protein (p-CREB)in developing rats.Methods A total of 72 Sprague-Dawley rats (1 9-23 g) were randomly divided into 4 groups (n =18 each):Group C:normal saline control group;R1,R2, R3 group received continuous intraperitoneal remifentanil 1,5,10 μg·kg-1 ·min-1 for 2 hours re-spectively.Both total volume of remifentanil and saline were 2 ml.The SpO 2 and pulse rates were mo-nitored during the experiment.Step-down test was used to evaluate the learning and memory ability, while Western blot analysis was performed to measure the expression of hippocampal p-CREB protein in 4 h,24 h,1 week when the rats were awake.Results Compared with group C,group R1 and R2, pulse rates of group R3 decreased significantly (P <0.05 ),but the changes of SpO 2 in each group were not statistically significant.At 4 h point:compared with group C and group R1,the error times in step-down test were increased in both group R2 and R3,the latencies were shortened (P <0.05);Compared with group R2,the error times were increased in group R3,latency was shortened (P <0.05).At 24 h point,compared with group C and group R1,the error times were increased in group R2,R3,latencies were shortened (P < 0.05 );Compared with group R2,the error times were in-creased in group R3,latency was shortened (P <0.05 ).The error times and latency of each group had not statistical significance in one week.At 4 h point,the expression of p-CREB protein in hippo-campus of group R3 downregulated compared with group C and group R1,R2,respectively (P <0.05).At 24 h point,the expression of p-CREB protein in hippocampus of group R2,R3 decreased compared with group C and group R1 respectively(P <0.05);The expression of p-CREB protein in each group had no statistical significance in one week.Conclusion 5-10 μg · kg-1 · min-1 dose of remifentanil can result in a decline of learning and memory ability in the developing rats in short-term,and the mechanism may relate to the inhibition of p-CREB protein expression in hippocampus.
