OBJECTIVE: Adopting methods of cell culture to explore the effects and mechanisms of Jianpi Bushen Huoxue Prescription (JPBSHXP), a traditional Chinese compound herbal medicine for strengthening spleen, reinforcing kidney and activating blood circulation, in inhibiting hematopoietic cells apoptosis in a mouse model of aplastic anemia (AA). METHODS: Blood serum of AA mice was made from an AA mouse model. Blood serums containing different traditional Chinese compound herbal medicine were made from rats after intragastric administration of JPBSHXP and its related decoctions, respectively. Bone marrow cells of normal mice were incubated by these blood serums for 24 hours, respectively. The apoptosis of the bone marrow cells were assayed by flow cytometry and transmission electron microscopy (TEM). RESULTS: It was indicated that the bone marrow cells of normal mice incubated with blood serum of AA mice displayed typical apoptosis. The apoptosis rates of bone marrow cells of the AA mice incubated by blood serum containing different traditional Chinese herbal medicine were decreased. The effect of Bushen (reinforcing kidey) Recipe was better than Jianpi (strengthening spleen) Recipe and Huoxue (activating blood circulation) Recipe, while the effect of JPBSHXP was the best. TEM results showed that the effect of Bushen Recipe was better than that of the Jianpi Recipe and the Huoxue Recipe, while the effect of JPBSHXP was the best. CONCLUSION: JPBSHXP and its related decoctions can significantly decrease the apoptosis rate of bone marrow mononuclear cells of the AA mice. It is inferred that JPBSHXP can promote bone marrow hematogenesis.

Objective To investigate the effects of ghrelin on proliferation of vascular smooth muscle cells(VSMC)and the expression of mitochondrial fusion 2(Mfn-2)in cultured human aortic smooth muscle cells(HASMCs).Methods HASMCs were cultured in vitro,treated with different concentrations(10-9,10-8,10-7,10-6,10-5 mol/L)ghrelin or 10-6 mol/L ghrelin for different time(0,6,12,18,24 h).Subconfluent HASMCs at passage 4-6 were used in experiments.MTT essay was used to investigate the effect on proliferation of HASMCs.RT-PCR and Western blot were used to analyse the expression of Mfn-2.Results 10-7-10-5 mol/L ghrelin inhibited the proliferation of HASMCs,and the inhibitory effect of concentration of 10-6 mol/L was the most obvious(P<0.01).Ghrelin inhibited the proliferation of HASMCs in 6-24 h,and it reached the peak at 24 h(P<0.01).10-6 mol/L ghrelin significantly increased the expression of Mfn-2 mRNA and protein(P<0.01).The up-regulation of 10-6 mol/L ghrelin on Mfn-2 mRNA and protein expression reached the peak at 18 h(P<0.01).Conclusion Ghrelin might inhibit the proliferation of HASMC by up-regulating the expression of Mfn-2.

Objective To investigate the clinical value of serum carbohydrate antigen (CA125,CA199)and vascular endothelial growth factor C (VEGF-C)in early diagnosis of ovarian carcinoma.Methods 51 cases of ovarian cancer patients with retroperitoneal lymph node dissection were performed in the observation group,including 23 cases of ovarian cancer retroperitoneal lymph node metastasis,32 cases of ovarian benign tumor were selected as the control group.The serum levels of CA199 and CA125 were detected by the method of chemiluminescence detection,and the serum VEGF-C level was detected by enzyme-linked immunosorbent assay (ELISA).Results The serum level of CA125 in patients with ovarian cancer (1 682.5 ±261.5)u/mL was significantly higher than that in the control group (30.5 ±6.3)u/mL(P <0.01),serum VEGF-C level in ovarian cancer patients (2 125.6 ±96.7)pg/mL was signif-icantly higher than that in the control group (1 738.0 ±79.8)pg/mL (P <0.01 ).The serum CA199 level of 51 patients with newly diagnosed epithelial ovarian cancer was (72.5 ±30.6)u/mL,serum CA199 level of the control group was (17.4 ±8.5)u/mL,CA199 level of retroperitoneal lymph node metastasis was (134.9 ±72.5)u/mL, ovarian cancer retroperitoneal lymph node metastasis CAl99 serum level were significantly higher than those without lymph node metastasis and the control group (t =7.39,18.34,all P <0.01).The diagnostic sensitivity,specificity and accuracy of serum VEGF-C +CA199 +CA125 in detection of ovarian cancer retroperitoneal lymph node metasta-sis were 95.5%,96.5%,99.5%.Conclusion Combined detection of CA125,VEFG-C and CA199 in serum has important clinical value in predicting lymph node metastasis of ovarian cancer.

Objective To study the precision of computer-aided preoperative templating for total hip arthroplasty. Methods Thirty patients (11 males, 19 females; age ranged from 42 to 85 years, mean 56 years) received unilateral total hip arthroplasty from March 2008 to December 2008. Preoperative tem-plating was done with LINK -Preop-PlanTM to compare the size of the planned hip joint with the size of the prosthesis, as well as the discrepancy of the limbs before and after operation. Results The predicted sizes of the prosthesis corresponded well with the actual ones. The cup size of the prosthesis completely matched the actual ones in 19 patients (63%), and the variation was within 1 size in 8 patients (27%) and ≥2 sizes in 3 patients (10%). The stem size of the prosthesis completely matched the actual ones in 19 patients (63%), and the variation was within 1 size in 9 patients (30%) and ≥2 sizes in 2 patients (7%). The variation of the cemented and cementless stem size of the prosthesis was within 1 size in 16 patients (89%) and 12 patients (100%), respectively, with no statistical difference (P > 0.05). The discrepancy of limb length was (9.0±8.5) mm preoperatively and (1.1±2.4) mm postoperatively. Conclusions Preoperative planning is of paramount significance in total hip arthroplasty. Computer-ai-ded preoperative templating can accurately anticipate the type of the prosthesis, which is helpful in correc-ting the discrepancy in leg length.

OBJECTIVE: To observe the clinical effect of Shengxueling Granule (SXLG) in treating idiopathic thrombocytopenic purpura (ITP), and to study its possible mechanism. METHODS: Eighty-six cases of ITP were divided into two groups randomly. Fifty-six cases in the treatment group were treated with SXLG, a traditional Chinese medicine, and 30 cases administered with Western medicine (prednisone) were taken as control. Patients in each group took drugs for three months and were under follow-up observation. RESULTS: In SXLG-treated group, the total effective rate in 3 months was 85.71%, similar to 83.33% in prednisone-treated group (P>0.05), while the total effective rate in 6 months in the SXLG-treated group was 91.07%, higher than 53.33% of the prednisone-treated group (P<0.01), and no obvious side-effects were observed. The patients' bleeding was alleviated or stopped, and their general condition was improved. And the blood platelet count (BPC) was increased, the platelet associated immunoglobulin (PAIg) and interleukin-4 (IL-4) were markedly dropped, the level of natural killer cells activity (NKCA) increased, and the rate of T lymphocyte subsets gradually returned to normal level. Megakaryocytes tended toward maturation on bone marrow smear after SXLG treatment. All differences above were statistically significant. CONCLUSION: SXLG is an effective and safe medicine for ITP. It can regulate the cellular immunity, inhibit the platelet antibody to reduce the destruction of the platelet and to increase the number of platelet, promote the differentiation and maturation of megakaryocyte, facilitate the production and release of platelet, lower the fragility of capillary, and prevent the hemorrhagic tendency.

Objective To observe the effect of Guanxinning Tablet (GXNT) on myocardial infarction and cardiac autonomic nervous function in rats with myocardial ischemia reperfusion injury (MI/RI).Methods Seventy SD rats were divided into 7 groups randomly (n=10);the sham group, the MI/RI group, 75 mg/kg, 150 mg/kg, 300 mg/kg and 600 mg/kg GXNT groups and 300 mg/kg Compound Danshen Tablets (DST) group.All rats were administered orally for 7 days, and then the MI/RI model was made by ligating the left anterior descending branch of coronary artery in rats.The changes of electrocardiogram were recorded and the electrocardiogram of J points and heart rate variability (HRV) parameters were analyzed.At the end of reperfusion, the myocardial infarct size was measured by using Evans blue and tetrazolium chloride (TTC) double staining, and pathological changes of myocardium were observed by HE staining.The changes of serum lactate dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA) and nitric oxide (NO) levels were also detected.Results Compared with MI/RI group, GXNT and DST groups were significantly reduced myocardial infarct size and inhibited the rising of serum LDH and CK activities (P < 0.05, P < 0.01), and also reduced the total or average value of J point during reperfusion (P < 0.05, P < 0.01).Meanwhile, GXNT and DST groups were markedly increased HRV and serum NO level as well as decreased serum MDA content (P < 0.05, P < 0.01), and improved myocardial tissue pathology.Conclusions GXNT can reduce the myocardial infarction in rats with MI/RI, and also improve the cardiac autonomic nervous function.
