Hepatocyte growth factor participates in many gynecologic and obstetric diseases such as gynecological tumor,endometriosis and hypertensive disorder complicating pregnancy by combination with its receptor c-Met.This article reviews the expression and mechanism of HGF in these diseases.

Objective To investigate the clinical effect of flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of irritable bowel syndrome with constipation (IBS-C) in elderly patients. Methods Fifty paients aged from 65 to 95 years with IBS-C were randomly divided into 2 groups: control group (23 patients) and treatment group (27 patients). The patients in treatment group received flupentixol and melitracen tablets (1 tablets, once a day) combined with macrogol 4000 powders (1 bag/time, 2 times a day) , while the patients in control group received macrogol 4000 powders alone. The treatment period was 4 weeks. The curative effect, the scores of self-rating depression scale (SDS) and self-rating anxiety scale (SAS) and adverse reaction were compared between two groups. Results At the improvement of depressive symptoms, the effective rate in treatment group and control group was 88.9%(24/27) and 39.1%(9/23), and there was significant difference (P<0.01). At the improvement of anxiety symptoms, the effective rate in treatment group and control group was 74.1%(20/27) and 26.1%(6/23), and there was significant difference (P<0.01). The total effective rate in treatment group and control group was 88.9%(24/27) and 65.2%(15/24), and there was significant difference (P<0.05). Conclusions Flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of aged IBS-C patients have more distinguished therapeutic effect in improving constipation symptoms, stools times, anxiety and depression.

Objective To evaluate the mutagenicity of mercury, cadmium, arsenic, chromium(Ⅵ)and lead in water on Vicia faba root tip cells. Methods The micronucleus assay of Vicia faba root tip cells were conducted to determine micronucleus rate of Vicia faba root tip cells induced by mercury (0.000 5-1.0 mg/L), cadmium (0.005-1.0 mg/L), arsenic(0.05-2.0 mg/L), chromium (Ⅵ) (0.05-2.0 mg/L) and lead (0.05-3.0 mg/L ) ,and pollution indexes were calculated. Results When the concentration of mercury was ≥ 0.5 mg/L, cadmium ≥ 0.1 mg/L, arsenic ≥ 0.5 mg/L and chromium(Ⅵ)≥ 2.0 mg/L in the water, the micronucleus rate were significantly higher compared with the negative control group, respectively(P

ISO 300 mg/kg ip markedly inhibited the corton oil induced ear inflammation in mice. Same dose ip showed significant inhibition on the hind-paw edema in rats induced by carragreenin. All these actions of ISO were similar to sod .salicy late.ISO 300 mg/kg im markedly inhibited the immunolpgical function in mice, but the potency was lower than prednisolone.

The growing number of cognitive dysfunction patients is bringing heavy mental and financial burdens to the society and families.Voltage-gated potassium channels (Kv), which consist of delayed rectifier potassium channels and transient outward po -tassium channels , are involved in the incidence of cognitive dysfunction .This review summarized the role of Kv channels in cognitive dysfunction and their relationship with N-methyl-D-aspartic acid receptors ( NMDARs) that play an important role in the process of learning and memory .

In vitro fertilization and embryo transfer (IVF- ET) technology is now widely used in the world in infertility patients. Psychological intervention can help the IVF- ET patients and their spouses reduce the negative emotions and improve pregnancy outcomes. This review provides a summary of the negative emotions in IVF- ET couples and the psychological intervention on them, so as to provide reference to establish a systematic and standardized clinical psychological nursing mode.

Objective:The drug resistance of E.coli to fluoroquinolones is getting stronger in the recent years.This study aimed at the drug resistance of E.coli induced by fluoroquinolones in vitro,so as to provide a guidance for the rational use of antibiotics and effective control of nosocomial infections.Methods: Drug resistance was induced in vitro by a multi-step method in 10 strains of E.coli from clinical isolates with Ciprofloxacin,Levofloxacin and Gatifloxacin.The minimal inhibition concentration(MIC) of the E.coli was determined by the agar dilution method before and after the induction.Results: After in vitro induction,the E.coli acquired a high resistance(MIC ≥ 128 ?g/ml).And one drug could induce different degrees of resistance to the other two.Conclusion: The MIC of the E.coli induced by fluoroquinolones in vitro was increased by 8 to 8 205 folds compared with that before induction,which demonstrated a gradually developed resistance of E.coli strains to fluoroquinolones.

Objective To explore the effect of psychological intervention combined with drug multimodal treatment on analgesic effect and stress reaction in Department of orthopedics.Methods80 cases of Department of orthopedics patients in Ruian City People's Hospital from March 2016 to March 2017 were selected and randomly divided into control group and observation group, 40 cases in each group.The control group was treated with drugs only, and the observation group was treated with psychological intervention combined with multi multimodal.The analgesic effect and stress response of the 2 groups were observed.ResultsThe satisfaction rate in observation group were significantly higher than the control group.There was no significant difference in heart rate, diastolic blood pressure and systolic blood pressure between two groups before intervention, after group intervention, the changs in observation group were relatively small, and the difference was statistically significant(P<0.05).Visual acupuncture scores were observed at different time points,the pain in the observation group was significantly lower than that in the control group, the difference was statistically significant (P<0.05).ConclusionMultimodal therapy for analgesia in the Department of orthopedics and found psychological intervention combined with stress reaction the drug, compared with simple drug intervention, can play a good analgesic effect, at the same time to reduce the patient's stress response, so it is worthy of reference.

Background Oxidative stress has been implicated in the pathogenesis of angiotensin Ⅱ(Ang Ⅱ)related hypertension.Superoxide anion,produced by NAD(P)H oxidase,plays important roles in hypertension and its complications.Ang Ⅱ infusion increases cerebral NAD(P)H oxidase activity,which is inhibited by angiotensin Ⅱ receptor blocker(ARB)candesartan and NAD(P)H oxidase inhibitor.However,the underlying mechanism of ARB in preventing hypertensive stroke is not elucidated clearly.Objective To investigate the effects of candesartan on the expression of cerebral NAD(P)H oxidase mRNA in salt-loaded stroke-prone spontaneously hypertensive rats(SHRsp).Methods Twelve-week-old salt-loaded SHRsp were treated with candesartan [1.0 mg/(kg?d)],trichlormethiazide [TCM,1.6 mg/(kg?d)] or vehicle(n=12 in each)for 2 weeks.Age-matched salt-loaded WKY rats were served as control(n=12).Blood pressure was measured every week.After two weeks,cerebrums were harvested and 24 h urine was collected.Urinary albumin was examined by ELISA.Cerebral cortex NAD(P)H oxidase subunits(p22phox,p47phox and gp91phox)mRNA expression were assayed by real-time PCR.Results The systolic blood pressure was increased significantly in salt-load SHRsp.Candesartan and TCM reduced SBP to the similar level.Urinary albumin excretion and cerebral cortex NAD(P)H oxidase subunits were markedly higher in salt-loaded SHRsp than those in salt-loaded WKY rats.Incidence of stroke was significantly reduced in candesartan treated group as compared with TCM treated SHRsp(P

ve To assess the cytogenetic toxicological safety of fish raised in water containing effluent. Methods The mutagenecity of organic extracts of uncooked meat specimens of fish raised in fishpond water mixed with sewage water taken from South and North Sewer Drainage Canals of Tianjin was detected by mice bone marrow micronucleus test. Results The organic extracts of uncooked fish meat specimens showed positive result for all of the 3 observed groups of fish raised in water of fish ponds with sewage, and negative result for fish raised in clean fishpond water in micronucleus test. Conclusion The results indicated that some kinds of organic mutagenic compounds ex-isted in the uncooked meat of fish raised in fishpond water containing effluent, which might have some potentially hazardous effects on human health through the food chains.
