The treatment and signaling pathway regulation effects of kidney- tonifying traditional Chinese medicine on osteoporosis have been widely studied, but without a systematic summary currently. This review comprehensively collected and analyzed the traditional Chinese medicine on the treatment and signaling pathway regulation of osteoporosis in recent ten years, such as Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen and Dipsacus. Based on the existing findings, we concluded the following conclusions: (1) kidney-tonifying traditional Chinese medicine treats osteoporosis mainly through BMP-Smads, Wnt/β-catenin, MAPK, PI3K/AKT signaling pathway to promote osteoblast bone formation and through OPG/RANKL/RANK, estrogen, CTSK signaling pathway to inhibit osteo?clasts of bone resorption. ① Epimedium, Drynariae Rhizoma, Cnidium and Psoralen up-regulate the key proteins and genes of BMP-Smads and Wnt/β-catenin signaling pathways to promote bone formation.② Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen, Dipsacusinhibit the bone resorption by mediating the OPG/RANKL/RANK signaling pathway. (2) Kidney-tonifying traditional Chinese medicine prevent and treat osteoporosis through a variety of ways: Icariin, Naringin, Osthol, Psoralen can regulate BMP-Smads, Wnt/β-catenin signaling pathway to promote bone formation, but also activate OPG/RANKL/RANK, CTSK and other signaling pathway to inhibit bone resorption. (3) The crosstalk of the signaling pathways and the animal experiments of the traditional Chinese medicine on the prevention and treatment of osteoporosis as well as their multi-target mechanism and comprehensive regulation need further clarification.

This study is to investigate the effect of low doses of insulin (1 u x kg(-1)) and selenium (180 microg x kg(-1)) in combination on general physiological parameters and insulin signal molecules in cardiac muscle of STZ-induced diabetic rats. The levels of blood glucose were estimated using One Touch SureStep Blood Glucose meter. HbA1c levels were estimated using microcolumn assay. TG and TC were estimated using enzymatic assay. The levels of PI3K and GLUT4 in cardiac muscle were examined by immunoblotting and immunohistochemistry. The result showed that insulin in combination with selenium could significantly lower blood glucose and blood lipid levels and markedly restored the PI3K and GLUT4 levels in cardiac muscle. It could be concluded that there was cooperation between insulin and selenium, and that treatment of diabetic rats with combined doses of insulin and selenium increased cardiac glucose uptake by upregulating the level of PI3K-mediated GLUT4 in cardiac muscle, eventually ameliorating myocardial dysfunction.

OBJECTIVETo investigate the protective effect and mechanism of curcumin derivatives B06 on myocardium from type 2 diabetic rats.

METHODSThirty-five male SD rats were randomly divided into 5 groups, normal control group (NC group), high fat group (HF group), high fat treatment group (FT group), diabetes mellitus group (DM group) and diabetes treatment group (DT group) (n = 7). The late four groups were fed with high fat food, after four weeks of high fat feeding, the rats from DM group and DT group were injected with low dosage of streptozocin intraperitoneally to induce diabetes mellitus, FT group and DT group were gavaged with curcumin derivatives B06 at the dosage of 0.2 mg/kg x d. The blood glucose and lipid were detected biochemically, blood insulin was assayed by ELISA and the insulin resistance index was calculated, the morphology of myocardium was observed by light and transmission electron microscopy, the protein expression of AMP-activated protein kinase alpha (AMPKalpha) and phosphorylated AMP-activated protein kinase alpha (p-AMPKalpha) in myocardium were tested by Western blot.

RESULTSThe level of blood glucose, lipid, insulin and the insulin resistance index were increased in HF group and DM group, but they were decreased after the treatment with B06. The expression of AMPKalpha and p-AMPKalpha were decreased, but they became increased after the treatment of B06. There were increased collagen fibers in interstitium and expansion of mitochondria in cytoplasm of myocardium from DM group, but they were ameliorated in B06 treatment group.

CONCLUSIONIt is suggested that B06 may relieve the damage of myocardium from type 2 diabetic rats and the increased expression of AMPKalpha and p-AMPKalpha may be involved in it.

OBJECTIVETo investigate the effects of ulinastatin (Uti) and low-molecular-weight heparin (Lmwh) on coagulation function and deep vein thrombosis (DVT) in patients undergoing hip joint replacement.

METHODSFrom March to December 2010 150 ASAI-II patients with average age of 72.5 (65 - 85) years undergoing hip joint replacement were randomly divided into 3 groups (n = 50 each): normal saline (NS) control group (Group C), Uti group (Group U) and Lmwh group (Group L). Group U received intravenous infusion of ulinastatin (10 000 U/kg) at preoperative, perioperative and after operation 1, 2 and 3 d, respectively. Group C received the same volume of NS instead of Uti. Group L were injected Lmwh subcutaneously (3200 U/d) at preoperative, after operation 1, 2 and 3 d. Blood samples were taken before operation (T(0)), at the end of surgery (T(1)), 1 d (T(2)), 2 d (T(3)) and 3 d (T(4)) after operation for determination the values of R, K, α angle, MA and CI, using thromboelastography, and the DVT were also examined through color Doppler ultrasonography at 3 d after operation.

RESULTSCompared with T(0), R, K were shorter, α angle, MA and CI were larger in group C, the values at T(2) were up to the peak then declined at T(4). Compared with group C, the value of R, K were larger, the value of α angle, MA and CI were shorter in group U and group L. The DVT checked by ultrasonography were found in 20 cases in group C, 1 case in group U, and zero case in group L. The differences were no statistically significant between group U and group L.

CONCLUSIONIntravenous infusion of Uti during the period of operation can correct the hypercoagulability of blood and decrease the incidence of DVT after operation.

BACKGROUNDTransurethral resection of prostate (TURP) has been widely used as a golden standard therapy of benign prostatic hyperplasia for over 40 years. However, not all patients achieved favorable outcome postoperatively. Since the level of bladder outlet obstruction and the dysfunction of detrusor (overactive and underactive) were both found to affect surgical efficacy, urodynamics was recommended as routine preoperative examination in selecting proper surgical candidates by International Continence Society in spite of its invasiveness and high cost. The aim of this research was to compare the predictive value between ultrasonography and urodynamics for TURP efficacy and determine if preoperative urodynamic test could be replaced by ultrasonography.

METHODSTwo hundred and seventy-one patients took part in the retrospective analysis. All the subjects had preoperative evaluation of symptoms, life quality, and combined examination of ultrasonography and urodynamics. Surgical efficacy was measured according to the recovery of international prostate symptom score, quality of life score, and maximal flow rate 6 months after TURP. Fisher's linear discriminant analysis was applied to establish the predictive models of surgical efficacy by choosing parameters from ultrasonography or urodynamics as independent factors. Receiver's operating characteristic curve was then plotted to compare the values between the models.

RESULTSSensitivity, specificity, positive and negative predictive value of models consisting of parameters from both ultrasonography and urodynamics were favorable. Corresponding models of ultrasonography and urodynamics were found to have non-significant difference in area under curve (P > 0.05).

CONCLUSIONSPreoperative ultrasonography has as strong value as urodynamics does in predicting surgical outcome of patients undergone TURP and might take the place of urodynamics in selecting surgical candidates. Further prospective analysis with larger popularity and longer period of follow up should be launched to verify the result of this research.

To determine heat-shock protein (Hsp)90 expression is connected with cellular apoptotic response to heat stress and its mechanism, chicken (Gallus gallus) primary myocardial cells were treated with the Hsp90 promoter, aspirin, and its inhibitor, geldanamycin (GA), before heat stress. Cellular viability, heat-stressed apoptosis and reactive oxygen species level under different treatments were measured, and the expression of key proteins of the signaling pathway related to Hsp90 and their colocalization with Hsp90 were detected. The results showed that aspirin treatment increased the expression of protein kinase B (Akt), the signal transducer and activator of transcription (STAT)-3 and p-IKKα/β and the colocalization of Akt and STAT-3 with Hsp90 during heat stress, which was accompanied by improved viability and low apoptosis. GA significantly inhibited Akt expression and p-IKKα/β level, but not STAT-3 quantity, while the colocalization of Akt and STAT-3 with Hsp90 was weakened, followed by lower cell viability and higher apoptosis. Aspirin after GA treatment partially improved the stress response and apoptosis rate of tested cells caused by the recovery of Akt expression and colocalization, rather than the level of STAT-3 (including its co-localization with Hsp90) and p-IKKα/β. Therefore, Hsp90 expression has a positive effect on cellular capacity to resist heat-stressed injury and apoptosis. Moreover, inhibition of Hsp90 before stress partially attenuated its positive effects.

OBJECTIVETo study the clinical effect and safety of early postnatal application of glucocorticoids in the prevention of bronchopulmonary dysplasia (BPD) in preterm infants.

METHODSThe databases including PubMed, Cochrane Library, Embase, CNKI, Wanfang Data, and VIP were comprehensively searched for articles on early postnatal application of glucocorticoids in the prevention of BPD in preterm infants published up to June 2016. Review Manager 5.3 was used for the Meta analysis of 16 randomized controlled trials (RCTs) that met the inclusion criteria.

RESULTSA total of 2 962 participants were enrolled in the 16 RCTs, with 1 486 patients in the trial group and 1 476 in the control group. The Meta analysis showed that early postnatal application of glucocorticoids reduced the incidence rate of BPD at a corrected gestational age of 36 weeks (OR=0.73, 95%CI: 0.61-0.87, P=0.0004), but there was an increase in the risk of hyperglycemia (OR=1.61, 95%CI: 1.24-2.09, P=0.0003), hypertension (OR=1.63, 95%CI: 1.11-2.38, P=0.01), and intestinal perforation (OR=1.51, 95%CI: 1.12-2.04, P=0.007).

CONCLUSIONSAt present, it is not recommended to use glucocorticoids to prevent BPD in preterm infants. Its advantages and disadvantages need further studies, with special focuses on the adverse effects of hyperglycemia, hypertension, and intestinal perforation.

OBJECTIVETo evaluate the correlation of clinical effect and prognosis between patients with metastatic colorectal cancer (mCRC) and different K-ras status.

METHODSThe clinical characteristics, chemotherapeutic regimens and survival of 153 mCRC patients with different K-ras status were analyzed retrospectively.

RESULTSThe median overall survival (OS) in patients without K-ras mutation were 31.7 months, significantly longer than 21.3 months in the patients with K-ras mutation (P = 0.037). The median progression-free survival (PFS) and OS in patients who received chemotherapy followed by anti-EGFR antibody treatment were 11.5 and 39.3 months, respectively, significantly longer as compared with the PFS and OS in those received chemotherapy in combination with anti-EGFR antibody concomitantly (5.7, P = 0.02, and 28.7 months, P = 0.034, respectively).

CONCLUSIONSK-ras status is a prognostic biomarker for mCRC patients treated with anti-EGFR antibody. The combination settings of anti-EGFR in combination with chemotherapy may improve survival of mCRC patients with wild-type K-ras status.
