Objective　To explore the effect of the psychological intervention on the treatment of dental anxiety (DA).Methods Measured with Corah's dental anxiety scale , 316DA patients were selected from department of dentistry and were divided into two groups: the intervention group and the control group . The psychological intervention as well as regular dental therapeutics were applied to the patients in the intervention group , whereas only regular dental therapeutics were used to those in the control group.Results　The patients had a lower clinical dental anxiety in the intervention group , significantly different from that of the control group ( P＜ 0.01). After the treatment , more patients in the intervention group had a slower pulse than those in the control group and fewer had a faster pulse .The results also showed that the psychological intervention had a better curative effect on male patients than female ( P＜0.05). Conclusion　The psychological intervention was efficient to patients with dental anxiety.

OBJECTIVE:To explore the effects of xingnaojing combined with naloxone on related indexes of patients with he-patic encephalopathy. METHODS:In retrospective analysis,76 patients with hepatic encephalopathy were divided into control group(40 cases)and observation group(36 cases)according to drug use. Based on routine treatment,control group was additional-ly given Naloxone injection 1 mg added into 10% Glucose solution 100 mL intravenously twice a day. Observation group was addi-tionally given Xingnaojing injection 20 mL added into 0.9% Sodium chloride injection 250 mL intravenously once a day on the ba-sis of control group. Treatment courses of 2 groups lasted for 2 weeks. HDS score,MMSE score,the levels of blood ammonia,β-endorphin,CRP,IL-6 and TNF-α,the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS:Af-ter treatment,HDS score and MMSE score of 2 groups were significantly higher than before treatment,and the observation group was significantly higher than the control group;the levels of blood ammonia,β-endorphin,IL-6,CRP and TNF-α in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statis-tical significance(P<0.05). There was no statistical significance in the level of IL-10 between 2 groups before and after treatment (P>0.05). There was no statistical significantly in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,Xingnaojing combined with naloxone can significantly improve cognitive function for patients with hepatic en-cephalopathy and reduce peripheral blood neurotoxin and inflammatory factor,moreover,do not increase the incidence of ADR.

Diabetic peripheral neuropathy( DPN) is one of the most common chronic complications and the disabling one, which is related to chronic hyperglycemia and microvascular changes. Currently, the treatments of diabetic peripheral neuropathy contains glu-cose control,pain management,etiological treatment,prevention and remove risk factors. So we make a review on the progress on the treatment of DPN by now , providing a scientific basis to a advanced and effective program.

OBJECTIVE:To explore the effects of the early use of heparin on the prognosis related indicators of patients with acute respiratory distress syndrome(ARDS). METHODS:Data of 86 ARDS patients were retrospectively analyzed and divided in-to observation group(45 cases)and control group(41 cases)by whether the early use of heparin. Control group received invasive mechanical ventilation,using end-expiratory pressure(PEEP)ventilation method,enteral nutrition support,nasogastric enteral nu-trition suspension 35-40 kcal/(kg·d);patients with combined infection were given Sodium ceftizoxime for injection 2 g,adding in-to 0.9% Sodium chloride injection 100 mL by intravenously infused,twice a day. Observation group was additionally given Hepa-rin sodium injection 6250 units by continuous intravenously pumped. They were treated for 14 d. The cumulative incidence of dis-seminated intravascular coagulation(DIC),and D-dimer,platelet count(PLT)before treatment and after 3,7,14 d of treatment, IL-6,IL-8,IL-10,TNF-α levels before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RE-SULTS:The cumulative incidence of DIC in observation group was significantly lower than control group,with statistical signifi-cance(P<0.05). Before treatment,there were no significant differences in the D-dimer,PLT,IL-6,IL-8,IL-10,TNF-α levels, with no statistical significance (P>0.05). After treatment,D-dimer,IL-6,IL-8 and TNF-α levels in 2 groups were significantly higher than before,while observation group was significantly lower than control group;PLT in 2 groups was significantly lower than before,while observaton group was higher than control group,with statistical significance (P<0.05). There was no signifi-cant difference in the IL-10 level in 2 groups before and after treatment (P>0.05). And there were no obvious adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,early use of heparin can significantly decrease the DIC rick for ARDS patients,which can improve coagulation disorders,reduce inflammatory response,and dose not increase the incidence of adverse reactions.

Objective To investigate the effect of geldanamycin(GA) on the expression of HSP(HSP90,HSP70,HSP27) and oncoprotein(mutant p53,CDK4) in human breast cancer cell line MDA-MB-435s.Methods Proliferation of MDA-MB-435s cells was measured with MTT assay.The mRNA expression levels of HSP90,HSP70 and HSP27 were detected by RT-PCR.The protein expression levels of HSP90,HSP70,HSP27,mutant p53 and CDK4 were detected by Western blot.Results GA inhibited the proliferation of MDA-MB-435s cells in a time-dose dependent manner.The expression level of mRNA and protein of HSP90,HSP70 and HSP27 were increased,and the increasing of HSP70 was the most significant,while the protein expression level of mutant p53 and CDK4 in MDA-MB-435s cells were reduced obviously after 48-hour treatment with 400 nmol/L GA as compared with that of control cells.Conclusion GA inhibits the proliferation of MDA-MB-435s cells by down-regulating the level of mutant p53 and CDK4 protein,and GA involves in the protection of cell stress through increasing the expression of HSP90,HSP70 and HSP27.

Objective To study the expression of P450arom(P450A)protein and mRNA in human ovarian endometriosis and normal endometrium and the relationship with its local estrogen abnormal synthesis.Methods PT-PCR was used to assess P450arom messenger RNA(mRNA)expression of 45 ovarian endometriosis and 35 normal eutopic endometrium;immunohistochemical assay was performed to locate and examin the protein expression of P450arom in the above cases.Results P450A mRNA level was higher in the ectopic endometrium than that in eutopic endometrium(P

Objective:To study the preventive and therapeutic effects of Acalypha decoction on 2,4,6-trinitrobenzene sulfonic acid induced ulcerative colitis(UC) in rats.Methods: Totally 70 male SD rats were equally randomized into 7 groups, and UC was induced by intrarectal administration of TNBS (125 mg/kg in 50% ethanol). Six hours later the rats were given 3 different doses of Acapha decoction (2.5, 6.5, 9.5 g crude drug/kg body weight) daily for 10 d.Some rats were pretreated with Acalypha decoction (6.5 g crude drug/kg body weight) 3 d before the colitis was induced. Sulfasalazine was used as the standard drug for comparison. The efficacy of Acalypha decoction was assessed through the following parameters: bodyweight loss, diarrhea and bloody stool, macroscopic score,histological changes,and MPO activity in colon tissue. Results: Acalypha decoction treatment(9.5 g/kg, 6.5 g/kg) and prevention administration (6.5 g/kg) significantly inhibited the bodyweight loss and occurrence of diarrhea and rectal bleeding in the rats(P

In inflammatory bowel disease, the experimental model s have been proven to be important tools to investigate the potential therapeuti c agent and to study the mechanism of pathogenesis. Literatures available were r eviewed on the methods of induction, characteristic and availability of all kind s of chemically induced IBD animal models. It would provide some information for selection of the experimental model in pharmacology and pathogenesis study.
