The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

A series of noscapine analogues have been synthesized via 13-step reaction starting from 2-hydroxy-3-methoxybenzaldehyde. Anti-tumor activities of these compounds were evaluated against HL-60 cell lines in vitro by the standard MTT assay. It was found that most of these derivatives showed appreciable inhibitory activity against HL-60 and tubulin polymerization. The results also indicated that the potency of compound 31 is about three times more than that ofnoscapine against HL-60 cell line and tubulin polymerization. Moreover, it induced a massive accumulation of cells in G2/M phase. These results showed noscapine and its derivatives were worth to be intensively studied further.

Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P＜0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P＜0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P＞0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P＜0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P＞0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

Objective To investigate the prevalence of glomerular microthrombosis in lupus nephritis (LN) and the significance of antibodies to anti-coagulation related factors and anti-phospholipid antibodies in glomerular microthrombosis (GMT).Methods Kidney biopsy specimens and plasma samples were obtained consecutively from 124 patients with LN. Kidney biopsy specimens were examined for the presence of glomerular microthrombi.Plasma samples from 25 LN patients with GMT (LN-GMT group) and 99 LN patients without GMT (LN-non-GMT group) were tested for lupus anticoagnlant (LA) and antibodies to cardiolipin (ACL),β2 glycoprotein I (β2GP I ),plasmin,thrombin,tissue plasminogen activator (t-PA) and Annexin A II.Results The prevalence of GMT in LN patients was about 20.2%.Compared to LN-non-GMT group,LN-GMT group had elevated SLE disease activity indices (SLEDAI),elevated activity and chronicity indices of kidney tissue injury,and elevated serum creatinine,blood urea nitrogen and proteinuria levels,and also had a higher frequency of hypertension (P＜0.01).The positive rates of LA,IgG class anti-β2GP I and anti-thrombin antibodies were higher in LN-GMT group than in LN-non-GMT group (P＜0.05).The positive rates of IgG class antibodies to ACL,plasmin,t-PA and Annexin A II in LN-GMT group were not statistically different from those in LN-non-GMT group (P＞0.05).No difference was found in the positive rate of any IgM class antibody between the two groups (P＞0.05).Conclusion This study has shown that GMT occurs approximately in 20.2% of the LN patients.Patients with GMT have more severe kidney tissue injury and more poor renal outcomes than patients without GMT.LA and antibodies to β2GP I and thrombin play a role in glomerular microthrombosis in lupus nephritis.

Objective To detect peripheral blood level of CD4+ CD25high CD127low regulatory T (Treg) cells in patients with B cell non-Hodgkin lymphoma (B-NHL) and to explore its clinical significance.Methods The levels of peripheral blood CD4+ CD25high CD127low Treg cells of 100 newly diagnosed patients with B-NHL and 50 healthy adults were detected and analyzed by flow cytometry.Results The levels of peripheral blood CD4+ CD25high CD12low Treg cells were 5.00 ％ and 7.20 ％ in healthy adults and newly diagnosed B-NHL patients,respectively.The difference was statistically significant (P ＜ 0.001).The level of peripheral blood CD4+ CD25high CD127low Treg cells was significantly higher in the male patients than that in the female (P ＜ 0.01).The level of peripheral blood CD4+ CD25high CD127low Treg cells was significantly higher in elevated LDH patients than that in normal LDH patients (P ＜ 0.01).The level of peripheral blood CD4+ CD25high CD127low Treg cells in stage Ⅲ-Ⅳ patients was significantly higher than that in stage Ⅰ-Ⅱ patients (P ＜ 0.01).The level of peripheral blood CD4+ CD25high CD127low Treg cells in B symptom patients was significantly higher than that in no B symptom patients (P ＜ 0.01).There was no significant relationship between the level of peripheral blood Treg cells and age,IPI score,bulky disease or pathologic subtype (all P ＞ 0.05).Conclusions B-NHL patients were in an immunosuppresive statue.Male,elevated LDH level,B symptom and Ⅲ-Ⅳ stage were correlated with higher level of peripheral blood CD4+ CD25high CD127low Treg cells.Level of peripheral blood Treg cells may be a useful prognostic factor for B-NHL.

Objective To study the incidence of osteopenia in patients with initial systemic lupus erythematosus(SLE). Investigate the levels of the vitamin D (VitD) endocrine system in peripheral blood of SLE patients and its relation to bone mineral density (BMD). Analyse the relationship between the estrogen receptor (ER) and BMD and evaluate the role of ER in the pathogenesis osteopenia. Methods Serum levels of 25-OH VitD_3 and 1,25-(OH)_2 VitD_3 were detected by enzyme linked immunosorbent assay. The gene expression levels of VitD receptor (VDR) and ER were determined by real-time PCR. BMD measurements in the lumbar spine (L1-L4) and left proximal femur (femoral neck) were performed using dual X-ray absorptiometry before treatment. Results The initial SLE patients had significantly lower BMD values, and higher frequency of bone loss at both sites of measurement compared with normal controls (P < 0. 05). The levels of 25-OH VitD_3 and 1,25-(OH)_2 VitD3 were lower in the initial SLE patients than normal controls(P<0.01 both). There is no difference in the levels of 25-OH VitD_3 and 1,25-(OH)_2 VitD_3 between the osteopenia SLE group and the normal BMD SLE group (P > 0. 05, P > 0. 05). There are no correlations between the Vitd and BMD in initial SLE patients (P>0.05 both). The expressions of VDR gene were significantly increased in the initial SLE patients compared with the normal controls(P<0.01). There was no difference in VDR gene expression between osteopenia SLE group and normal BMD SLE group (P>0.05). The VDR gene expression does not correlate with the bone mass (P>0.05). The levels of ER-β gene expression are higher in the initial SLE group than the normal controls (P<0.01).Conclusions The incipient SLE patients may have lower BMD than expected. SLE patients present abnormal VitD endocrine system and higher ER-β mRNA expression than those in normal controls, but these weren't concerned with osteopenia.

ObjectiveTo find out the inhibitory effects of CD4 - CD8 - DNT cells on growth of which depresses the pancreatic cancer in vitro and in vivo.Methods The inhibitory effects of DNT cells on the growth of Panc- 1 were studied in vitro by MTT method.Eighteen BALB/c mice were divided into 3 groups randomly.Human pancreatic cancer xenografts were established in 2 groups randomly.The last group was injected the cell suspension which comprises DNT and Panc- 1 cells ( Panc- 1∶ DNT =1∶ 5 ).When the diameter of tumor was about 5 mm,the first 2 group mice were further divided into 2 groups randomly.One was control,treated with distilled water.The other was treated with celebrex (4 mg/d).The size of the tumors was calculated every 2 weeks and tumor growth curve was depicted.At the end of the treatments,the mice were sacrific and the tumors were harvested.The tumor inhibition rate was calculated.Results( 1 ) MTT study showed that DNT cells produced a dose- dependent inhibition of Panc- 1 proliferation in vitro.(2) The growth of transplanted pancreatic cancer was down-regulated by treatment of DNT cells.ConclusionDNT cells can inhibit the growth of pancreatic cancer in vitro and in vivo.

Objective ① To investigate the level of the vitamin D endocrine system in peripheral relationships with bone mineral density (BMD) and the disease activity respectively. Methods The level of the 25-hydroxylate vitamin D3 (25OHD3) and 1,25-dihydroxyvitamin D3 [1,25(OH)D3] in plasma from 43 SLE patients and 44 normal controls were detected by enzyme linked immunosorbent assay. Vitamin D receptor (VDR) gene expression was determinied by real-time PCR in peripheral blood. BMD measurements in the lumbar spine (L1-4) and left proximal femur (femoral neck) were performed using dual X-ray absorptiometry before treatment. The relationship between the vitamin D endocrine system and the bone mass were studied. We also discussed the relationship between the vitamin D endocrine system and the disease activity. Results The levels of 25OHD3 and 1,25 (OH)2D3 were lower in the initial SLE patients than normal controls (P<0.01, P<0.01). The expressions of VDR gene were significantly increased in initial SLE compared with normal controls (P<0.01). The initial SLE patients had significantly lower BMD values, and higher frequency of osteopenia (35%) at both sites of measurement compared with matched healthy controls (P<0.01). The initial SLE patients were divided into two groups by BMD, abnormal group and normal group. There were no differences in 25OHD3, 1,25 (OH)D3 and VDR gene expression (P0.05). There was no correlation between the vitamin D endocrine system and BMD in initial SLE patients. There was no correlation between the vitamin D endocrine system and the disease activity either. Conclusion Vitamin D endocrine system may play an important role in SLE, but the level of VDR gene is not correlated with BMD and disease activity.
