OBJECTIVE:To study the effect of catalpol on the activity and apoptosis of osteoclasts (OC) in the osteoblasts (OB)-OC co-culture system and its mechanism. METHODS:OB and OC were isolated respectively from the SD rats of 1-3 days and 5-7 days old to establish OB-OC co-culture system. After treated with 0(blank control),0.05,0.5,5,50 and 100 mg/L catal-pol for 48,72 and 96 h,the number of bone absorption lacuna for OC was observed by inverted microscope to reflect OC activity. After treated with 0(blank control)and 0.05 mg/L catalpol for 48,72 and 96 h,the activity of tartrate resistant acid phosphatase (TRACP)in OC was detected,and the apoptosis rate of OC was calculated. After treated with 0(blank control)and 0.05 mg/L ca-talpol,mRNA expression of osteoprotegerin(OPG)in OB was detected. RESULTS:In OB-OC co-culture system,the number of bone absorption lacuna in 0.05-50 mg/L catalpol groups was significantly lower than blank control group(P<0.01),indicating ca-talpol could inhibit OC activity,especially 0.05 mg/L catapol. Compared with blank control,0.05 mg/L catapol lowered the activity of TRACP but increased the apoptosis rate of OC(P<0.05);mRNA expression of OPG was up-regulated in OB(P<0.01). CON-CLUSIONS:In OB-OC co-culture system,catalpol can inhibit the activity of OC and induce the apoptosis of OC,and its mecha-nism may be associated with the mRNA expression up-regulation of OPG in OB.

AIM: To investigate the angiogenesis effect and protective mechanism of cordycepin on rhesus macaque choroid- retinal endothelial ( RF/ 6A) cell line cultured in high glucose condition.
METHODS: Cultured RF/ 6A cells were divided into normal control group, high glucose group and high glucose (HG) + different concentration cordycepin groups (HG+ 10μ g/ mL group, HG+ 50μ g/ mL group, HG+ 100μ g/mL group). The cell proliferation was assessed using cholecystokinin octapeptide dye after treated for 48h. The cell migration was investigated by a Transwell assay. The tube formation was measured on Matrigel. Furthermore, the impact of cordycepin on high glucose - induced activation of VEGF and VEGF receptor 2 (VEGFR-2) was tested by Western blot analysis.
RESULTS: Compared with normal control group, cell viability markedly increased in high glucose group ( P <0. 05). Cordycepin inhibited RF/ 6A cell proliferation in a dose- dependent fashion: 10. 2 ± 0. 9%, 23. 4 ± 1. 5% and 31. 1±1. 2% inhibition as the concentrations of cordycepin were 10, 50 and 100μ g/ mL, respectively. The difference had statistically significant (P<0. 05) compared with high glucose group. The number of cell migration were 55. 6±2. 70, 87. 4 ± 2. 40, 65. 4 ± 2. 7, 57. 8 ± 2. 38, 62. 4 ± 2. 77 in normal control group, high glucose group and HG+10μ g/mL group, HG + 50μ g/ mL group, HG + 100μ g/ mL group respectively. Migration of RF/ 6A conspicuously increased in high glucose group ( P < 0. 05) compared with normal control group; while showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference compared with high glucose group (P<0. 05). The number of tube formation were 18. 7±2. 08, 25. 7 ± 1. 52, 19. 9 ± 1. 57, 16. 3 ± 2. 51, 5. 67 ± 1. 72 in the abovementioned group. Similarly showing a gradually reducing trend with the increase of cordycepin dose and a statistically significant difference with high glucose group (P< 0. 05). In addition, the number of tube formation of RF/ 6A in high glucose group significant increased compared with normal control group ( P < 0. 05 ). The expression of VEGF and VEGFR-2 dramaticlly increased in high glucose group vs normal control group, oppositely gradually decreased with the increase of cordycepin concentrations, and had a statistically significant difference vs high glucose group (P<0. 05).
CONCLUSION: Cordycepin can suppress the proliferation, migration and tubu formation of RF/ 6A in high glucose condition, might via inhibiting expression of VEGF and VEGFR-2.

To investigate the effect of compound Chinese traditional medicine PC-SPES II I in inhibiting proliferation of human prostate cancer cell LNCaP based on the androgen receptor (AR) signaling pathway. The effect of PC-SPES II on LNCaP cell proliferation was detected by MTT assay. According to the findings, at the mass concentration of 180-1 440 mg x L(-1), PC-SPES II significantly inhibited the proliferation of LNCaP cells; the IC50 of PC-SPES II at 24 h and 48 h were 311.48, 199.01 mg x L(-1), respectively. The flow Cytometry detection showed 240 mg x L(-1) PC-SPES II arrested cells in G2/M phase, and an obvious apoptotic peak appeared before G0/G1 peak and rose over time. Meanwhile, Hoechst 33258 staining revealed apoptotic cellular morphology. Annexin V-FITC/PI staining manifested an increase in apoptotic cell ratio at the PC-SPES II concentration of 480 mg x L(-1) in a dose dependent manner. The prostate specific antigen (PSA) secretion of LNCaP cells was tested by PSA ELISA kit. Besides, compared with 25 mg x L(-1) Bic, 480 mg x L(-1) PC-SPES II significantly reduced the cell secretion of PSA. The AR and PSA mRNA and protein expressions were detected by qRT-PCR and Western blot. According to the results, after the induction of LNCaP cells with synthetic androgen 25 μg x L(-1) R1881, 240-480 mg x L(-1) PC-SPES II notably down-regulated the AR and PSA mRNA and protein expressions and inhibited the translocation of AR from cytoplasm to nucleus. In summary, PC-SPES II significantly can inhibit the in vitro proliferation of LNCaP cells and arrest cell cycle arrest in G2/M phase. Its mechanism may be associated with the down-regulation of the AR and PSA expressions and the inhibition of AR nuclear translocation.

Objective To investigate the low density lipoprotein receptor (LDLR)gene and apolipoprotein (Apo) B gene mutation in a Chinese family with familial hypercholesterolemia(FH) and give the kindrids clinical check-ups. Methods After physical examination, the kindreds underwent ECG and ultrasound checks. Blood samples were tested for lipid profiles. The promoter and all eighteen exons of LDLR gene were investigated by using PCR and agarose gel electrophoresis in combination with DNA sequence analysis. The results were compared with the normal sequences in GenBank and FH database ( www. ucl. ac. uk/fh ) to find mutations. In addition, the apolipoprotein B100 gene for known mutations (R3500Q,R3531C,R3501W and R3480W)that cause familial defective ApoB100 (FDB)was also tested using the same method. Results A novel homozygous G ＞ A mutation at the 1581 bp of exon 10 was detected in the proband and his siblings. It caused a substitution of amimo acid Glu to Gly at codon 496. A novel heterozygous G ＞A mutation at the 1581 bp of exon 10 was detected in his parents. No mutations of R3500Q,R3531C,R3501W and R3480W of ApoB100 were observed. ECGs were normal. Atherosclerosis were found in all family members by ultrasound checks. Conclusions The homozygous G ＞ A mutation at the 1581 bp of exon 10 was first determined in our country. The change of amino acid Glu to Gly is responsible for FH of the family. The type of the gene mutation was not found in the FH database( www. ucl.ac. uk/ih). It's a new type of LDLR mutation.

Objective To investigate the role ofglutamic acid decarboxylase autoantibody(GAD-Ab)and protein tyrosine phosphatase autoantibody(IA-2A) in postpartum follow-up of gestational diabetes mellitus (GDM).MethodsGAD-Ab,IA-2A,insulin and glucose metabolism index were measured in 82subjects with normal glucose tolerance (control group) and 84 patients with GDM(GDM group) during 24 to 28 weeks in pregnancy,postpartum 6 to 12 weeks and 2 years.GDM group was divided into antibodies positive group (GAD-Ah or IA-2A were positive) with 18 cases and antibodies negative group (GAD-Ab and IA-2A was negative) with 66 cases.Results Homeostasis model insulin resistance index (HOMA-IR) in GDM group was higher than that in control group (3.87 ± 2.17 vs.2.31 ± 0.52,P ＜ 0.05 ).Homeostasis β -cell function index (HBCI) and 30 min net increment of insulin/30 min net increment of glucose ( △ I30/△ G30) in GDM group were lower than those in control group[206.38 ± 138.06 vs.422.43 ± 228.93 and (20.16 ±11.38) mU/mmol vs.(26.54 ±24.30) mU/mmol,P ＜0.05].The numbers who had the family history of diabetes mellitus and the used of insulin for treatment in antibodies positive group were higher than those in antibodies negative group[ 83.3％ (15/18) vs.28.8％ (19/66) and 77.8％ ( 14/18 ) vs.30.3％ (20/66) ],HOMA-IR,△ I30/ △ G30 and HBCI in antibodies positive group were lower than those in antibodies negative group [3.20±0.84 vs.4.02±0.36,(16.81 ±2.91) mU/mmol vs.(21.55± 11.11) mU/mmol and 124.95 ± 5.03 vs.217.43 ± 115.64,P＜ 0.01 ].Fasting plasma glucose (FPG),2 hours postprandial glucose (2hPG)and glycosylated hemoglobin (HbA1c) in antibodies positive group were higher than those in antibodies negative group during postpartum 6 to 12 weeks and 2 years [postpartum 6 to 12 weeks: (8.20 ±3.11)mmol/L vs.(5.39 ±0.76) mmol/L,(15.22 ±7.29) mmol/L vs.(8.15 ± 1.93) mmol/L,(7.26 ± 1.04)％ vs.(5.88 ±0.41)％ ;postpartum 2 years: (8.91 ±2.80) mmol/L vs.(4.93 ±0.66) mmol/L,(15.75 ±7.87)mmol/L vs.(7.85 ± 1.79) mtmol/L,(7.18 ± 1.22)％ vs.(5.64 ± 0.32 )％,P ＜ 0.01].△ I30/ △ G30 and HBCI were significantly decreased in antibodies positive group postpartum 2 years.No change of the above parameters in antibodies negative group was found.The occurrence rate of type 1 diabetes mellitus (T1DM) was 16.7％(3/18) and 33.3％(6/18) postpartum 6 to 12 weeks and 2 years in antibodies positive group,there was no T1DM in antibodies negative group.ConclusionsWomen with GDM are partly associated with T1DM.Requiring insulin therapy during pregnancy and GAD-Ab or IA-2A positive have considerable risk for developing T1DM.It is also an important predictor to GDM after parturition.

Objective To probe into the clinical features, ways of diagnosis and treatment measures of concurrent paratyphoid fever A after renal transplantation. Methods The 5 patients were all town or village people under the county level. After the operation, the immunosuppressive scheme of ciclosporin A (or Tacrolimus) + mycophenolate mofetil (MMF) + prednisone acetate was adopted. One case was caused by catching cold and the rest 4 had no any distinct inducement. Five patients fell ill respectively at the 5th, 7th, 7th, 9th and 14th month after the operation. On the admission, the 5 patients suffered from gastrointestinal symptoms such as vomiting and diarrhea to varying degrees; 3 from toxic symptoms such as fever, intolerance of cold, hypodynamia and headache; 3 from symptoms of the respiratory system such as stuffy nose and congestion of throat; 1 from elevation of blood pressure; 1 from relative slow pulse. In 3 patients with decrease of urine volume, 1 suffered from gross hematuria, swelling of transplanted area of the kidney, pain on pressure and rise of blood pressure. Only 1 patient's paratyphoid fever A antibody in the Widal's test gastroenteritis or untoward reaction of MMF and the curative effect was bad. After definite diagnoses,the combined treatment of the third-generation cephalosporin and FQNS were given to all of them.After treatment for 7-10 days, the symptoms in all patients all disappeared. During the treatment, 1 patient was diagnosed as acute rejection and given the methylprednisolone shock for 3 days. After that, the patient's graft function was improved; 3 patients suffered from relatively great fluctuation of blood concentration of immunosuppressive agent and toxic symptoms such as decrease of the graft function, etc. After adjustment of dosage, their indicators of renal function became normal. Conclusion Early symptoms and accessory examinations of paratyphoid fever A after renal transplantation lack specificities. Diagnosis of paratyphoid fever A after renal transplantation mainly depends on blood culture. Drugs of first choice include FQNS and the third-generation cephalosporin. During the treatment, the doctor should closely monitor blood concentration of the immunosuppressive agent.
