OBJECTIVE:To evaluate the efficacy and safety of salmon calcitonin plus Xianling gubao for osteoporosis and ostealgia in postmenopausal women. METHODS:160 women with postmenopausal osteoporosis and ostealgia were randomized to 3 groups (treatment group and 2 control groups):the treatment group received(500 IU q.d) salmon calcitonin nasal spray plus Xianling gubao(1.5 g b.i.d orally); the control group Ⅰ received(500 IU q.d) salmon calcitonin nasal spray alone and the control group Ⅱ received Xianling gubao(1.5 g b.i.d orally) alone. All the patients received oral Caltrate D (1 tablet q.d). A course was defined as 30 days. After treatment for a total of 3 courses,the nature and degree of ostealgia in all the patients were assessed,and the outcome indexes were measured and the adverse drug reactions were recorded. RESULTS:There were significant differences between the treatment group and two control groups in total effective rates(92.59% for treatment group vs. 69.81% for control group Ⅰ and 67.92% for control group Ⅱ,P0.05). CONCLUSION:Treatment of osteoporosis and ostealgia in postmenopausal women with salmon calcitonin plus Xianling gubao has been proved to be safe and effective in that the bone density can be increased effectively and the osteoporotic pain of lumbar and back of the patients can be relieved.

Objective The different distribution and clinical significance of mean platelet volume (MPV) in the healthy normoglycemic and impaired fasting glucose (IFG) individuals were discussed.Methods The 499 individuals including 184 male and 315 female,who had undergone health checks in Tianjin Huanhu Hospital during May and July 2012 were studied retrospectively.Average age is forty-five ( thirty-five to eighty).Subjects were categorized into four groups according to fasting plasma glucose ( FPG) levels:G1 (3.89 mmol/L≤FPG<5 mmol/L, n=125),G2(5 mmol/L≤FPG <5.5 mmol/L, n=121), G3(5.5 mmol/L≤FPG<6.1 mmol/L, n=142), and G4(6.1 mmol/L≤FPG<7 mmol/L, n=111).G1, G2, and G3 are defined as normal FPG groups and G 4 is defined as IFG group.Eighty-nine cases in the same age patients with type II diabetes mellitus group ( G5 ) were observed at the same time.Results The MPV increased with the increasing FPG levels in the following order:G1(8.62 ±0.77) fl, G2 (8.85 ±0.80) fl, G3(8.90 ±0.69) fl,G4(9.14 ±0.78) fl and G5(12.03 ±1.42) fl.MPV[(12.03 ±1.42) fl] of type Ⅱdiabetes mellitus group(G5) was higher than that in the IFG group (G4)[(9.14 ±0.78) fl] and normal FPG groups[G1(8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01);MPV of the IFG group [ ( 9.14 ±0.78 ) fl ] was significantly higher than that in normal FPG groups [ G1 (8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01 for G4 vs.G1 and G2, P<0.05 for G4 vs.G3) ;MPV in the high-normal glucose group (G3) [(8.90 ±0.69) fl] was obviously higher than that in the low-normal glucose group (G1) [(8.62 ±0.77) fl] (F=12.773,P<0.05);MPV was positively associated with FPG in normal FPG groups ,IFG group and type Ⅱ diabetes mellitus group (G1-3:r=0.22, P<0.05;G4:r=0.26, P<0.01;G5:r=0.29, P<0.01).Conclusions Significant difference of MPV was observed in population of different FPG levels.Especially, MPV in IFG group was evidently higher than that in normal FPG group and was positively associated with FPG levels.

ObjectiveTo investigate the value of urinary BNP for diagnosis of chronic heart failure (CHF). MethodsThe levels of Urinary BNP and plasma BNP were measured by microparticle enzyme immunoassay (MEIA) in 83 patients with CHF and 30 control subjects. The heart function was classified according totheNYHAcriteria. Leftventricularejectionfractions(LVEF)weremeasuredby echocardiology. ResultsThe level of urinary BNP in patients with CHF was[90. 0(38. 3 -209. 5 )]ng/L and the level of plasma BNP was[680. 0 ( 289. 7 - 1543.5)]ng/L, both of them were much higher than those in healthy subjects,[17. 0 ( 13.0 - 33. 0)]ng/L and[84. 5 ( 56. 0 - 158.0 )]ng/L, respectively (P＜0. 01 ). The concentrations of urinary BNP increased gradually with more severe symptoms ( NYHA cl ass Ⅰ -ⅣV ). The level of urinary BNP was positively correlated with NYHA class ( r = 0. 742, P ＜ 0. 01 )and the level of plasma BNP (r =0. 842,P ＜0. 01 ) while negatively related with LVEF (r = -0. 801 ,P ＜0. 01 ). The level of urinary BNP in patients with LVEF ＜ 40％ was[143.0 ( 85. 0 - 258.0)]ng/L , which was much higher than that in patients with LVEF≥40％ ,[31.5( 17.3 -38. 8)]ng/L, (P ＜0. 01 ). At a decision threshold of 36. 5 ng/L, the urine BNP assay demonstrated a clinical sensitivity and specificity of 84％ and 80％ ,respectively. In this study,the area under the curve(AUC) was 0. 905. ConclusionUrinary BNP is a new candidate marker for the diagnosis of CHF,it provides a similar accuracy with plasma BNP.

AIM: To set the model of rat bone marrow me se nchymal stem cells (BMMSCs) that differentiate into cardiomyocytes and observe t he connection structure between cells. METHODS: BMMSCs were isolated by adhering to culture plates and cultured in vitro to expand. Induction of BMMSCs to differentiate into cardi omyo cytes was conducted by treating the cells with 5-aza. Immunocytochemical stainin g was used to identify sarcomeric actin and intercalated disc-like structure wh en the cells were cultured for additional 1 week, 2 or 3 weeks, respectively. RESULTS: Sarcomeric actin positive cells were observed in 1 week , 2 or 3 weeks after 5-aza treatment. Some cells stained positive for connexin4 3 at 1 week and 2 weeks after 5-aza treatment, with brown pellet located disper sively around nucleus. 3 weeks after 5-aza treatment, connexin43 positive cells s howed brown pellet arranging in thready structure around nucleus, such structure could be seen between very few cells which was similar to intercalated disc-lik e structure in normal heart tissue. CONCLUSION: During the process of BMMSCs differentiating into ca rdiomyocytes, intercalated disc-like structure is gradually formed with increas e in culture time and cell density.

Objective To study the clinical features and treatment of cervical spondylosis with dissociated motor loss in upper extremity. Methods Data analysis was done in 10 patients with cervical spondylosis with dissociated motor loss in upper extremity, in aspects of symptoms, sign, radiologic feature, electromyogram and treatment. Results There are 2 subtypes of cervical spondylosis with dissociated motor loss in upper extremity: Keegan and Non-Keegan types. The patients with Keegan type of cervical spondylosis manifested weakness and atrophy in the upper extremity, and no radicular pain was reported. The Non-Keegan type is in fact a combination of radicular and spinal insult in the cervical region. Our clinical practice showed that surgical operation was preferred to the conservative treatment for patients with this disease. Conclusion A well understanding of this disease is of great importance for avoiding mistakes in diagnosis and treatment of this disease.

Objective To investigate the efficacy and safety of tirofiban for emergency interventional therapy in patients with acute ST segment elevation myocardial infarction.Methods The 96 acute ST segment elevation myocardial infarction patients having accepted emergency percutaneous coronary intervention (PCI) were divided into treatment group and control group according to the treatment method with 48 cases each.The treatment group was given conventional standard treatment combined with tirofiban treatment [tirofiban intracoronary injection 10 μ g/kg and then intravenous 0.15 μ g/(kg· min) for 24-48 h].The control group was given conventional standard treatment only.The postoperative 60 min electrocardiogram ST segment recovery,the coronary blood flow TIMI grade,the major adverse cardiac events (angina,myocardial infarction,heart failure,death) and postoperative bleeding in 4 weeks were compared between the two groups.Results The patients having postoperative 60 min electrocardiogram ST segment recovery in treatment group was 45 cases (93.8％,45/48),in control group was 35 cases (72.9％,35/48),and there was statistical difference (P ＜ 0.05).The incidence rate of infarction vascular TIMI grade ≥ 3 grade flow in treatment group was 95.8％ (46/48),in control group was 75.0％ (36/48),and there was statistical difference (P ＜ 0.05).The incidence rate of the major adverse cardiac events 4 weeks in treatment group was significantly lower than that in control group,and there was statistical difference (P ＜ 0.05).There was no statistical difference in the incidence rate of bleeding between the two groups (P ＞ 0.05).Conclusion In patients with acute ST segment elevation myocardial infarction,the emergency interventional therapy with tirofiban is efficacy and safety.

Objective To investigate the role of microRNA-155 (miR-155) on post-transcription regulation of SH2 domain-containing inositol 5'-phosphatase 1 (SHIP1) gene expression in the pathogenesis of acute myeloid leukemia (AML).Methods Quantitative real-time polymerase chain reaction (RT-PCR) was performed to detect the expression of miR-155 and SHIP1 mRNA in the AML patients and controls.miR-155 mimics was transfected into U937cells (U937m) by using X-treme GENE siRNA transfection reagent.Cells without transfection (U937c) and cells with negative transfection (U937mc) were used as controls.RT-PCR was performed to detect the expression of miR-155 and SHIP1 mRNA in these cells.The expression of SHIP1,TAKT and pAKT were detected by Western blot in U937 cells.Apoptosis was studied by flow cytometry (FCM).Results The average level of SHIP1 protein content in 15 samples of patients with AML-M4 or AML-M5 from 30 AML patients was significantly lower compared with that of patients with the other types of AML,and the levels of miR-155 were significantly higher in the same group of patients (P ＜ 0.05).Significantly decreased levels of SHIP1 protein were found in U937m cells compared that of U937c and U937mc (P ＜ 0.05).Significantly decreased rate of apoptosis was observed in U937m cells compared with that of U937mc and U937c.U937m cells also exhibited no alteration in total AKT content,while increased p-AKT levels were found (P＜ 0.05).Conclusion SHIP1 was also a primary target of miR-155 in AML.Overexpression of miR-155 could activate PI3K-AKT pathway to depressing SHIP1 and decrease the apoptosis rate of AML cells.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P ＜ 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps ＜ 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps ＞ 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps ＜ 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P ＜ 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

OBJECTIVETo explore the effect and mechanism of electroacupuncture (EA) for Z syndrome without organic lesion (metabolic syndrome combined with obstructive sleep apnea hypopnea syndrome).

METHODSFifty-eight patients with Z syndrome were divided into three groups according to mild,moderate and severe degree. Acupuncture and EA were used at Daimai (GB 26), Zhongwan (CV 12), Xiawan (CV 10), Zusanli ST 36), Qihai (CV 6) and Huaroumen (ST 24), etc., once a day and five times a week. The treatment of ten times was a course, and two courses were acquired continuously. Sleep respiration monitoring (PSG) was done before EA and in one week after treatment respectively. Triacylglycerol (TG) fasting blood glucose (FBG) fasting insulin (INS) and serum leptin (Lep) were tested before and after treatment in the three groups.

RESULTSAfter treatment apnea hypopnea index (AHI) and the percentage of the time of arterial oxygen saturation (SaO₂) less than 90% taken in the total sleep time (SLT 90%) were improved apparently than those before treatment in the three groups (all P < 0.05). The levels of TG, FPG, INS and Lep were decreased after treatment in all groups (all P < 0.05).

CONCLUSIONEA can improve AHI and nocturnal hypoxia of Z syndrome, and the mechanism may be related to decreasing the indices of metabolism syndrome and leptin.
