AIM:To investigate the effects of high concentration of glucose on the expressions of serum and glucocorticoid induced protein kinase 1 (SGK1) and fibronectin in human podocytes and detect the production of fibronectin in human podocytes transfected with active and mutant forms of SGK1.METHODS: The expressions of SGK1 and fibronectin in human podocytes exposed in high glucose for 24 h were detected by using Western blotting. Human podocytes were transfected with three kinds of plasmid: pIRES2-EGFP-SGK1SD (SGK1-active plasmid), pIRES2-EGFP-SGK1KN (SGK1-mutant plasmid) and pIRES2-EGFP (empty vector plasmide). The synthesis levels of fibronectin were detected by immunofluorescence.RESULTS: The expression of SGK1 in normal human podocytes was observed and the expression level was up-regulated in podocytes exposed to high glucose for 24 h (50?4 vs 35?3), parallelly with the high expression of fibronectin (19?4 vs 12?2). The secretion of fibronectin was increased obviously in SGK1-active plasmid (SGK1SD) transfected podocytes compared with the vector transfected podocytes. Whereas, the fibronectin level was decreased significantly but not completely abolished in SGK1-mutant plasmid (SGK1KN) transfected podocytes, compared with SGK1SD transfected podocytes. CONCLUSION: SGK1 may be involved in the synthesis of fibronectin in human podocytes induced by high glucose and play a critical role in the activation of human podocytes during early stage of diabetic nephropathy.

OBJECTIVE: To observe the influence of repeated shallow fire-needle acupuncture stimulation plus cupping on local neuralgia and serum substance P(SP)content in patients with acute herpes zoster (AHZ). METHODS: A total of 60 cases of AHZ patients were randomly divided into control (medication) group and treatment (medication plus fire-needle) group (n＝30 in each). Patients of both groups were ordered to take Famciclovir (0.25 g/time, three times a day) and Mecobalamin (0.5 g/time, three times a day) orally for 7 days. In addition, patients of the treatment group were also treated by repeated shallow fire-needle stimulation and cupping, once a day for 7 days. Before and after the treatment, the patient's pain severity was assessed using visual analogue scale (VAS) and serum SP concentration was measured using ELISA. RESULTS: After the treatment, the VAS scores and serum SP concentrations in both groups were significantly decreased in comparison with those of their own pre-treatment (P<0.01), and were significantly lower in the treatment group than in the control group(P<0.01). There was a highly positive correlation between the decreased VAS score and serum SP content in the treatment group(P<0.01). CONCLUSION: Repeated shallow fire-needle stimulation plus cupping can accelerate the relief of local neuralgia in AHZ patients, which may be associated with its effect in down-regulating serum SP level.

Objective:To optimize the formulation of HA-CA liposomes and to study the anti-tumor effect of HA-CA liposomes on uterine cervical carcinoma mice.Methods:The methods of preparing HA-CA liposomes were screened,and the optimal fomulation was selected by the orthogonal design experiment with the the phospholipids/cholesterol ratio,the drug/lipids ratio and the pH value of PBS buffer was 7.4 as entrapment enfficiency was the index.The release of HA-CA liposomes was studyed by dialysis bag method.Uterine cervical carcinoma cells were inoculated subcutaneously into right axillary ofBal b/c mice,after continuous treatment of 14 d,we weighed the tumor and calculated the rate of tumor growth inhibition.Results:HA-CA liposomes were prepared by thin film hydration methods.The optimal parameters were as follows:the phospholipids/cholesterol ratio was 4∶1,the drug/lipids ratio was 1∶ 30,the pH value of PBS buffer was 7.4.The release curve of HA-CA liposome and CA liposome was basically the same,both of which a sustained-release efficacy.The cumulative release of HA-CA liposomes and CA liposomes were 78.39％ and 83.01％ at 48h.The inhibition rate of HA-CA liposomes on U14 cervical cancer mice was 60.39％ and significantly higher than that of positive control group,which was higher than that of CA and CA liposomes.Conclusions:HA-CA liposomes can significantly inhibit the effect of U14 cervical cancer nude mice higher than that of CA and CA liposomes owe to the modification of the active target ligand HA.

Objective To investigate the methods of steroid supplement following adrenalectomy in the patients with Cushing syndrome.Methods The methods and outcome of steroid supplement following adrenalectomy in 75 cases of Cushing syndrome were retrospectively reviewed.Results Supraphysiological doses of glucocorticoid was given during the perioperative period,and the dosage was reduced gradually.Prednisone with a dosage of 5 to 7.5 mg was given once a day on discharge.In the patients with adrenocortical adenoma,4 to 15 month of steroid supplement was required.The patients undergoing bilateral adrenalectomy required lifelong steroid supplementation.Steroid withdrawal syndrome occurred during steroid tapering in 8 patients with adrenocortical adenoma,2 of them had normal plasma cortisol level.Conclusion In the patients with Cushing syndrome,even those with normal plasma cortisol level might have steroid withdrawal syndrome episodes during steroid tapering.

Objective To investigate the impact of multi-drug transporters including P-glycoprotein (PGP) and multi-drug resistance associated protein (MRP) on concentration of lamotrigine in the extracellular fluid in hippocampus of epilepsy rat models induced by pilocarpine, and to deduce the multi-drug resistance mechanisms in refractory epilepsy. Methods The epilepsy rat models were established by repeated administration (by ip) of pilocarpine. A microdialysis probe was placed into the hippocampus of the epileptic rats and dialysate was collected at five time-points from 30--150 minutes after systemic injections of lamotrigine (10 mg/kg). The concentration of lamotrigine in the extracellular fluid in the hippocampus was determined by high-performance liquid chromatography (HPLC). Then PGP inhibitor verapamil and MRP inhibitor probenecid was added individually through microdialysis probe and the concentration of lamotrigine was detected again. Results Compared with control group (0. 41 ± 0. 10 in 60 minutes, 0. 50 ±0.04 in 90 minutes, 0. 39 ±0. 09 in 120 minutes and 0. 30±0.06 in 150 minutes), verapamil significantly increased the concentration of lamotrigine in extracellular fluid of the hippocampus 60--150 minutes (0. 65 ±0. 11, 0. 84 ± 0. 09, 0. 70± 0. 09 and 0. 58 ± 0. 08 respectively) after injection (F value were 5.01, 8.61, 10. 23 and 7.89, all P < 0. 05) and probenecid also enhanced the concentration of lamotrigine 90--150 minutes (0. 75 ± 0. 09, 0. 58±0. 10 and 0. 49±0. 07) after injection (F = 6. 58, 4. 56, 4. 75, all P < 0. 05). Conclusions Penetration of lamotrigine through blood-brain barrier in pilocarpine induced epilepsy rats is restricted by PGP and MRP, resulting in decreased concentration of lamotrigine in the extracellular fluid of the hippocampus. Therefore, increasing expression of PGP and MRP in brains of epilepsy patients might be an important mechanism involved in multi-drug resistance in refractory epilepsy.

Objective To study the influences of hepatolobectomy on space learning capability and the expressions of Drebrin and PSD95 in the hippocampus in APP/PS1 transgenic mouse model of Alzheimer's disease.Methods A total of fifty-four 3-month-old APP/PS1 transgenic mouse were randomly divided into 3 groups:3-month-old control group,sham surgery group,hepatolobectomy group,3-month-old littermates control group and 6-month-old control group.Morris water maze test was used to observe space learning capability on the 1st,3rd,7th,14th day after surgery,meanwhile the expressions of Drebrin and PSD95 in hippocampus were measured by Western blotting.Results Compared with the sham surgery group,the results of the Morris water maze test were decreased in hepatolobectomy group at day 3,7,14 after surgery [(62.9±6.9) s vs.(35.7±12.2) s,(66.3± 9.5) s vs.(39.3±8.3) s,(67.1±7.5) s vs.(32.6±14.1) s],and 6-month-old control group [(75.9±12.1) s] (all P＜0.05).The escape latency were (62.9±6.9)s,(66.3±9.5)s,(67.1± 7.5)s and (75.9±12.1)s,the probe trials were (2.1±0.7) times,(1.83±1.5) times,(2.5±1.9) times and (1.8±0.8) times respectively in hepatolobectomy group at day 3,7,14 after surgery and 6-month old control group.No significant differences in the results of the Morris water maze test were found among 3-month-old control group,3-month-old littermates control group,and sham surgery group.Compared with 3-month-old control group and sham surgery group atday 1,3,7,14 after surgery the expressions of Drebrin were decreased in 6-month-old control group and the hepatolobectomy group at the same time points.Meanwhile,the expression of Drebrin in hepatolobectomy group was increasedat day 14 versus day 7 after surgery.Compared with 3 month-old control group,the expression of Drebrin was increased at day 7 after sham surgery.Compared with 3-month-old control group and sham surgery group at day 3,7 and 14,the expressions of PSD95 were decreased in hepatolobectomy group at the same time points.Compared with 3-month-old control group,the expression of PSD95 was increased in sham surgery group at 7th day (P＜0.05).Between 3 month-old control group and 3-month-old littermates control group,the expressions of Drebrin and PSD95 had no significant differences.Concltsions Hepatolobectomy can impair the capabilities of space learning and memory in 3-month-old APP/PS1 transgenic mice,which may be associated with the decreased expressions of Drebrin and PSD95 in hippocampus.
