Objective To ob serve the clinical effect of blood-activating and stasis-dissolving drugs combined with western medicine ( WM) for the treatment of recurrent spontaneous abortion ( RSA) induced by prethrombotic state ( PTS). Methods A total of 120 patients with RSA at PTS were randomly assigned to treatment group (68 cases) and control group (52 cases). Patients in both groups were treated with aspirin and low molecular weight heparin, while those in the treatment group additionally received Chinese medicine for activating blood and dissolving stasis. Before and after treatment, indexes of coagulation-fibrinolysis and the development of embryos were compared between the two groups. Results The therapeutic effective rate was 88.24% in the treatment group, higher than that of the control group ( 69.23%, P<0.05). The levels of plasma thrombin time ( TT) , D-dimer, fibrinogen and antithrombin Ⅲ ( AT-Ⅲ) were all improved ( P<0.05) in the two groups after treatment. Besides, the treatment group had better effect on improving levels of plasma D-dimer, fibrinogen and AT-Ⅲ ( P<0.05). During the treatment, no drug-induced adverse reaction was found. Neither neonatal deformity nor maldevelopment occurred. Ninety-seven cases achieved successful pregnancy, and 45 cases had given term girth ( 29 cases from the treatment group and 16 from the control group). Fifty-two cases were in stable middle- and late-stage of pregnancy. Conclusion Therapy of activating blood and dissolving stasis is an effective method for RSA at PTS. It has obvious effects on improving high coagulation state during pregnancy. Chinese medicine combined with WM shows better therapeutic efficacy than WM alone.

Objective To induce adult adult adipose-derived stem cells(ADSCs) in vitro to differentiate into neuronal-like cells,and to analyze the features of their cell morphology and ultrastructure. Methods Adipose stromal cells were obtained and amplified in vitro. Then make use of chemical induction to induce them. Observed ADSC and differentiation of cells in morphology and ultrastructure under inverted microscope and transmission electron microscopy. Immunocytochemistry to detection of Nestin, Neuron Specific Endolase( NSE) ,and glial fibrillary acidic protein(GFAP) expression in cells. Used Real-time PCR to detection of Nestin,GFAP gene mRNA expression before and after induction in ADSC. To observe the morphology and ultrastructure of the cells prior to and after induction under microscope and electron microscope. Results The morphology of ADSC was similar to fibroblasts ,and could be amplified stability within 10 passages in vitro. Some of the cells induced display a typical astrocyte-like cells in ultrastructure. Followed neuronal induction,astrocyte-like cells began to stain brightly for CFAP, Nestin. GFAP stained in both the cytoplasm and nuclei of astrocyte-like cells, but Nestin only stained in the cytoplasm. The peak positive expression rate within 14d following neuronal induction. The rate of positive expression cells was( 14.4 ± 3. 6) % for Nestin, (87. 3 ± 5. 3 ) % for GFAP. Then two kinds of protein expression remained the similar rate. The average relative concentration of GFAP and Nestin gene mRNA have significant statistical difference between ADSC and differented cells analyzed by Real-time PCR (P<0.05).The peak concentration of GFAP was within 20 d after induction,and GFAP was within 14 d after induction. Conclusion In the cytoplasm of adult adipose-derived cells possess Nestin genetic material,which is the marker of neural stem cell. The differential astrocyte-like cells have the typical morphology, ultrastructure and GFAP phenotype of mature astrocytes.

Objective To reseach the time point of the highest percentage of neural precursor cells derived from adipose stromal cells (ADSCs) in vitro, and to observe the ultrastructure features of neural precursor cells. Methods Used the β-mercaptoethanol to induce ADSCs to differentiate into neural precursor cells and neuron-like cells. The morphology of the uninductedcells and inducted cells were observed with inverted phase contrast microscope. The expression of nestin which was the marker of neural precursor cell in each group was detected using immunofluorescence staining method. The ultrastructural feature of cells which was induced for 3 hours were observed. Results The highest ratio of positive expression of nestin was 3 hours following induction,with the ratio ( 86.25 ± 4.82) %. There were many protuberance on the cell membrane under transmission electron microscopy.There were plenty of organelles in the neural precursor cells. The neural precursor cells had a large size nucleus,large nucleoplasmic index, much extended chromatin,and less condensed chromatin. The nucleus had double-layer nuclear envelope, more nuclear pore on the nuclear envelope. Conclusion The time point of the highest percentage of neural precursor cells derived from ADSCs is 3 hours,and the ultrastructral feature of induced neural precursor cells confirm that cells at this time point are in a state of split active period.

Objective: To observe the therapeutic efficacy of warm needling moxibustion plus intra-articular injection of sodium hyaluronate in treating chondromalacia patellae and its effect on inflammatory factors in knee joint fluid. Methods: Sixty-eight patients with chondromalacia patellae were randomized into a control group and an observation group, with 34 cases in each group. The control group was treated with intra-articular injection of sodium hyaluronate, while the observation group was given additional warm needling moxibustion treatment. Before and after treatment, the two groups were scored using Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analog scale (VAS), examined by magnetic resonance imaging (MRI) and determined for the levels of nuclear factor-κB (NF-κB), tumor necrosis factor (TNF)-α and interleukin (IL)-1β in knee joint fluid. Clinical efficacy was estimated after treatment. Results: The effective rate was higher in the observation group than in the control group (P<0.05). After treatment, the scores of pain, stiffness and daily activities, as well as the general score of WOMAC declined significantly in both groups (all P<0.05), and were lower in the observation group than in the control group (all P<0.05); the time cost for climbing up and down one staircase and VAS score decreased markedly in both groups (all P<0.05), and were shorter or lower in the observation group than in the control group (both P<0.05); the MRI grading showed no significant change in the control group after intervention (P>0.05), while the grading in the observation group showed notable improvement (P<0.05), and was better than that in the control group (P<0.05); the levels of NF-κB and IL-1β in knee joint fluid dropped significantly in the control group after treatment (both P<0.05), while the levels of NF-κB, TNF-α and IL-1β in knee joint fluid all decreased significantly in the observation group (all P<0.05) and were lower than those in the control group (all P<0.05). Conclusion: Warm needling moxibustion plus intra-articular injection of sodium hyaluronate can produce definite efficacy in treating chondromalacia patellae; it can mitigate the clinical symptoms, improve the lesion extent of chondromalacia and down-regulate the levels of NF-κB, TNF-α and IL-1β in knee joint fluid.

Objective To assess the prevalence of carotid atherosclerosis in adult patients with KaschinBeck disease(KBD) in endemic area, and to investigate the association between KBD and atherosclerosis. Methods B-mode ultrasound was used to investigate carotid atherosclerosis in patients with KBD over 40 years old in Shanhe farm and Shangzhi city and residents in Shuangcheng county in 2009. Ultrasonography images were saved and graded according to intima media morphology. Results The prevalence rates of carotid atherosclerosis in patients with KBD from the 5 villages affiliated to Shanhe farm were 50.0%(26/52),37.3%( 19/51 ),42.5%(30/71 ),58.2% (39/67) and 44.0% (22/50) , respectively. The prevalence rates of carotid atherosclerosis in patients with KBD from the 5 villages affiliated to Shangzhi city were 63.0% (34/54), 45.3% (24/53), 47.2% (25/53), 60.0% (30/50)and 51.9% (28/54), respectively. The prevalence rates of carotid atherosclerosis in people without KBD in the 5 control villages affiliated to Shuangcheng county were 63.9% (46/72),43.1% (31/72),57.1% (40/70),46.9% (30/64) and 53.0%(35/66), respectively. Ten villages in KBD endemic area and 5 villages in control area were investigated. The prevalence rates of carotid atherosclerosis in the 15 villages were standardized and compared by Wilcoxon test. The differences were not significant between two KBD endemic areas and one control( T = 25.0,24.5,all P ＞ 0.05). There was no significant difference in prevalence of atherosclerosis in the 3 areas(x2 = 0.36, P＞0.05). Comparing the severity of carotid atherosclerosis in 3 locations, the difference was statistically significant (x2 = 15.28, P ＜ 0.05) and there was significant difference statistically between the subjects in Shangzhi city and that in the control group(x2 = 8.92, P ＜ 0.05). There was no significant difference between the detection rate of atherosclerosis and the severity of KBD, and similar results in the grade of atherosclerosis and the severity of KBD were found (x2 = 1.88,5.07, all P ＞ 0.05). Conclusions The prevalence rate of carotid atherosclerosis in historical endemic area in Heilongjiang province is not higher than that in the control area.

Objective To verify the association between common breast cancer susceptibility loci which have been confirmed in European and Asian populations and breast cancer susceptibility in sporadic breast cancer among the Han nationality in Henan province , and to analyze their genotypes in the internal type of breast cancer . Methods In 253 breast cancer patients ( the case group ) and 343 patients who had benign breast lesions ( the control group), rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)were genotyped by SNP im-LDR technique.According to estrogen receptor(ER), progesterone receptor (PR), human epidermal growth factor receptor 2(HER2)and Ki67, breast cancer are divided into 5 types:Lu-minal A, Luminal B, HER2-enrich, Luminal HER2, and triple negative breast cancer ( TNBC).Results rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1)had no statistical differences between the case group and the control group(P=0.421, 0.459, and 0.468), but the genotype of rs3803662(TOX3/TNRC9)in the case group and the control group had statistical difference (P=0.037).The allelic frequencies of rs3803662 between the case group and control group were different in codominant inheritance ( OR=2.19, 95%CI:1.19-4.02)and recessive genetic models (OR =2.06,95% CI:1.15 -3.70).Compared with AA and GA, GG in-creased the risk of breast cancer ( P =0.012, 0.015 ).The genotypes of rs2046210 ( 6q25.1 ), rs2981582 (EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)had no difference in different types of breast cancer.Conclusions Four common breast cancer susceptibility loci from GWAS are not entirely associated with breast cancer risk among the Han nationality in Henan province .Only rs3803662(TOX3/TNRC9)is confirmed to increase the risk of breast cancer .Different genotypes of 4 loci distribute equally in different types of breast cancer .

OBJECTIVETo explore the effect of Shoutai Pill (STP) containing serum on bioactivity behaviors of trophoblast cells in spontaneous abortion (SA) patients such as cell proliferation, invasion, migration and secretion.

METHODSTrophoblast cells in artificial abortion in normal pregnancy and SA patients were isolated and cultured in vitro, which were then treated with STP containing serum at various concentrations (5%, 10%, 20%, respectively). Blank serum was taken as the normal control group and dydrogesterone containing serum as the dydrogesterone control group. The proliferation, cycle distribution, invasion and migration capacity, and beta human chorionic gonadotropin (p-HCG) level were detected by methyl thiazolyl tetrazolium (MTT) colorimetry, flow cytometry (FCM), Transwell experiments, and ELISA, respectively.

RESULTSCompared with the normal control group, the activity of cell proliferation obviously decreased, ratios of apoptotic cells (SubGO/G1) and G2/M phase were obviously elevated, S phase cell ratio was obviously reduced (all P < 0.05). Transwell experiments indicated invasion and migration capacity obviously decreased, secreted beta-HCG level were obviously reduced after 72-h intervention (P < 0.05). Compared with the SA group, the activity of cell proliferation obviously increased, ratios of apoptotic cells and G2/M phase were obviously reduced, S phase cell ratio was obviously elevated, invasion and migration capacity were obviously enhanced, secreted beta-HCG level were obviously elevated after 72-h intervention in the dydrogesterone control group and each STP containing serum group (all P < 0.05). The activity of trophoblastic cell proliferation, S phase cell ratio, invasion and migration capacity, and secreted beta-HCG level were strengthened along with increased STP containing serum. Besides, the effects of 20% STP containing serum group were significantly superior to those of the dydrogesterone control group (P < 0.05).

CONCLUSIONSTP containing serum could dose-dependently enhance the proliferative activity of trophoblastic cells, invasion and migration capacity, secretion of beta-HCG, and reduce the apoptosis of trophoblast cells, which might be one of mechanisms for STP preventing and treating SA.
