AIM: To explore the protective effect of pretreatment with pentamethylquercetin(PMQ) on anoxia/reoxygenation (A/R) injury and mitochondrial function in rat cardiomyocytes. METHODS: Primary neonatal SD rat cardiomyocytes were cultured and pretreated with PMQ in final dose of 10, 30, 100 μmol/L for 24 h, and then underwent A/R injury. After treatment, the activity of LDH was determined by auto-biochemistry analysator, cells viability was analyzed by MTT, cell apoptosis and mitochondrial membrane potential were detected by flow cytometry, opening of mitochondrial permeability transition pore (mPTP) was determined by Ca²⁺-induced swelling of isolated cardiac mitochondria.RESULTS: Pretreated with different dose of PMQ (10, 30,100 μmo/L) for 24 h could reduce LDH activity, increase cell viability, decrease cell apoptosis(P<0.05 or P<0.01)in dose-dependent manner; Moreover, pretreated with 30, 100 μmol/L PMQ for 24 h, mitochondrial membrane potential could be more stable(P<0.05 or P<0.01), and the opening of mPTP could be more lessened(P<0.05 or P<0.01). CONCLUSION: Pretreated with PMQ for 24 h could have Pharmacology delay protection, the mechanism involved in stabilizing mitochondrial membrane potential, inhibiting mPTP opening, and reducing cell apoptosis.

AIM: To observe the in vitro effects of Agrimoni Pilosa aqueous extract on platelet aggregation, coagulation function and hemorheology, and to explore its related mechanisms of action on hemostatic and coagulation function. METHODS: Platelet rich plasma (PRP) and platelet poor plasma (PPP) from volunteers were mixed with 0, 4 , 20 and 80 g/L Agrimoni Pilosa aqueous extract. The maximal platelet aggregation rate (PAR) of PRP induced by adenosine diphosphate (ADP) with platelet aggregation analyzer, expression levels of P-selection and fibrinogen receptor (Fg-R) were detemined by Flow cytometry. Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (Fg) of PPP were detected with blood coagulation analyzer, respectively, blood cloting time (CT) and plasma ionized calcium (Ca²⁺) were detected with manual method and blood-gas analyzer, respectively, coagulable factor VII, VIII, IX and XI were detected by poor factor plasma correcting test. Blood viscosity, plasma viscosity and index of red cell aggregation were measured with hemorheology analyzer. RESULTS: At 4 g/L group, PAR, Fg-R and P-selectin expression levels were significantly lower than those at 0 g/L group (R<0.01). There was negative correlation between extract dose and any one of PAR, Fg-R and P-selectin level, but positive correlation between extract dose and inhibitory rate of platelet aggregation (R<0.01). At 4 g/L group, APTT, CT and FVII levels were remarkably higher , but PT, FVIII, FIX and FXI levels were lower, than those at 0 g/L group (R<0.01). APTT, CT and FVII levels showed positive correlation, but PT, FVIII, FIX and FXI levels showed negative correlation with extract dose (R<0.01). At 4 g/L group, levels of blood viscosity (1 s^-1 and 200 s^-1), plasma viscosity and index of red cell aggregation were markedly higher than those at 0 g/L group (R<0.01). They all indicated positive correlation with extract dose (R<0.01).CONCLUSION: Agrimoni Pilosa aqueous extract has anticoagulation efficacy mainly via platelet aggregation and coagulation function inhibition caused by inhibition of platelet Fg-R activation, secretion reaction and blood coagulable factors of intrinsic pathway, respectively. The extract is able to promote blood coagulating via activating blood coagulable factors of extrinsic pathway and increasing blood viscosity.

AIM: To observe effects of curcumin on oxidative damage in intestines of newborn rats with necrotizing enterocolitis (NEC) , as well as investigate the potential mechanism of NEC. METHODS: Twenty four Sprague-Dawley (SD) rats were randomly divided into 3 groups right after birth. Rats in the groupⅠwere subjected to formula feeding, cold stress, hypoxic-reoxygenation treatment as well as LPS intragastric administration. NEC intestinal damage was evaluated by histological scoring. Animals in group II were managed according to the same way except the intraperitoneal injection with curcumin. Rats in Group Ⅲ were delivered naturally and were dam fed. All rats were weighed every day and sacrificed on the 4th day. Proximal intestines of ileocecal junction were undertaken pathological sectioning and evaluated for pathological scoring by hematoxylin and eosin (HE) staining. The activity of intestines malonaldehyde (MDA),superoxide dismutase (SOD) and the expression of heme oxygenase-1(HO-1) in all rats were also detected respectively. RESULTS: Compared with group Ⅲ, rats in groupⅡshowed better growing development, improved physical activity and milder intestine gross characteristics than groupⅠeven after the same stress. The pathological scores were significant different among these three groups (P<0.05). Intestinal MDA concentration increased with the severity of intestine injure (P<0.05). SOD activities of group I and II decreased than that of group III. There was a significant difference in the first two groups (P<0.05). The expression of HO-1 was significant increased in groupⅠand group Ⅱ.The difference between the two groups was statistical significant (P<0.05).CONCLUSION: Curcumin could alleviate the intestinal injure in the experimental necrotizing enterocolitis rats. The potentional mechanism might be reducing intestinal oxidative damage through upregulating the expression of HO-1, decreasing MDA concentration as well as enhancing the activity of SOD.

AIM: To evaluate the relationship between the expression of excision repair cross-complement 1 (ERCC1) gene and platinum-based chemotherapy sensitivity in non-small cell lung cancer. METHODS: Database including Medline (1991.1-2009.12), Pubmed, CBMDisc were searched and randomized clinical trials as well as retrospective case studies were collected. Meta analysis was executed using RevMan 4.2 software. RESULTS: One randomized controlled trial (RCT) and nine case reports were identified and anlyzed. The results of nine case reports indicated that the response rate of ERCC1-negative patients to platinum-based chemotherapy was obviously higher than that of ERCC1-positive patients(P=0.02). One retrospective research reported longer time to progression (TTP) (P<0.05) and two reported longer overall survival in ERCC1-negative patients (P<0.05) compared with those ERCC1-positive patients. The results of RCT indicated that adjuvant chemotherapy significantly prolonged survival among low ERCC1 expression patients compared with observation but not among patients with high ERCC1 expression. Better adjuvant regimen for high ERCC1 patients is needed.CONCLUSION: Low ERCC1 expression patients are benefit from platinum-based chemotherapy, but patients with high ERCC1 expression are not sensitive to platinum-based chemotherapy. ERCC1 is a useful biomarker to clinically predict the efficacy of adjuvant chemotherapy in NSCLC.

AIM: To compare the clinical efficacy and safety of perospirone and quetiapine in the treatment of senile dementia patients with behavioral and psychological symptoms. METHODS: 106 cases of senile dementia patients were randomly divided into the perospirone group and the quetiapine group. The efficacy and adverse reaction were evaluated by Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Cohen-Mansfield Agitation Inventory (CMAI), Mini-Mental State Examination (MMSE), Activity of Daily Life (ADL) and Treatment Emergent Symptoms Scale (TESS) in baseline and after 12 weeks of treatment. RESULTS: After 12 weeks of treatment, the efficiacy rate was 82.0% in perospirone group and 85.7% in quetiapine group.There were no significant differences between the two groups (P>0.05). The scores of BEHAVE-AD and other factors were significantly decreased after the 12 weeks of treatment with perospirone, especially factors of hallucinations, behavior disorders and aggressive behavior (P<0.01). The MMSE and ADL scores of two groups after the 12 weeks of treatment were higher than the scores before treatment, but there were no significant differences between before and after treatment. The adverse reactions of perospirone group was lower than that of quetiapine group, but there were no significant differences between the two groups. CONCLUSION: Compared with quetiapine, perospirone has similar efficacy and safety in the treatment of behavioral and psychological symptoms of senile dementia, and fewer adverse reactions were found in perospirone group.

AIM: To investigate the safety and efficacy of dexmedetomidine(DEX) combined with propofol for sedation of patients undergoing painless enteroscope. METHODS: Sixty six patients with ASA I-II requiring enteroscope were randomized to (Group D, n=33) and (Group P, n=33). After venous pass way was conducted, the mean arterial pressure(MAP), heart rate(HR),hemoglobin oxygen saturation levels(SpO₂)were recorded. Group D received DEX 0.1μg/kg and Group P received saline placebo 3 mL initial loading dose, followed by propofol 1.5mg/kg, according to the body activity and operation time, whether to add propofol 30-50 mg or not. And the consumed dose of propofol, the body movement response, respiratory depression were recorded. RESULTS: Compared with Group D, the total administered dose of propofol, the time of patients awaken, the body activity in Group P were increased. During the painless anesthesia, propofol could lead to the circulation inhibition and the heartbeat was significantly quickened. Dexmedetomidine has little influence on the circulation, but it induced the decreased of heart rate. CONCLUSION: There were more efficacy and safe for DEX combined with propofol for sedation of patients undergoing painless enteroscope.

miRNAs are endogenous non-coding single-stranded small RNA molecule and are predicted to regulate 30% of all human genes by targeting mRNA sequences in their 3'UTR. As important post-transcriptional regulators, miRNAs play a positive role in various biological processes, including proliferation, differentiation, apoptosis, metabolism, and so on. Recent studies have indicated that miRNAs are associated with caner, cardiac disease, diabetes, Parkinson syndrome and multidrug resistance. Herein the article reviews the regulation on miRNAs to osteoporosis.

Recently, bevacizumab in the treatment of advanced breast cancer is controversial. Although the E2100 had doubled the progression-free survival when bevacizumab was added to chemotherapy, this magnitude of benefit could not be replicated in subsequent studies. Furthermore, individual studies and meta-analyses failed to demonstrate an overall survival benefit with the addition of bevacizumab to different chemotherapy regimens. The US FDA has withdrawn the approval of bevacizumab as a therapeutic option for the treatment of metastatic breast cancer in November, 2011; because that it cannot prolong the overall survival time. In addition, this agent is associated with an increased incidence of serious adverse events such as hypertension, congestive heart failure and thromboembolism, and its cost is likely to be a consideration in its use worldwide. Reevaluation of the benefit-versus-risk is indispensable. Biomarker-based studies aiming to identify the subpopulation of patients most likely to benefit from the addition of bevacizumab to standard chemotherapy in breast cancer should be a research priority in future.
