OBJECTIVE:To compare therapeutic efficacy and safety of indapamide separately combined with benazepril,irbe-sartan or amlodipine for grade 2 essential hypertension(EH). METHODS:A total of 150 patients with grade 2 EH were randomly divided into benazepril group(50 cases),irbesartan group(50 cases)and amlodipine group(50 cases). 3 groups were given Indap-amide tablet 2.5 mg orally,once a day. Benazepril group was additionally given Benazepril hydrochloride tablet 10 mg orally,once a day;irbesartan group was additionally given Irbesartan tablet 150 mg orally,once a day;amlodipine group was additionally giv-en Amlodipine tablet 5 mg orally,once a day. 3 groups were treated for 12 weeks. The levels of systolic pressure,diastolic pres-sure,heart rate,total cholesterol(TC),three triacylglycerol(TG)and serum potassium as well as the occurrence of ADR were ob-served in 3 groups before and after treatment. RESULTS:The total response rate of berazopril group,irbesartar group and a mloelip-ire group had no significant difference(90.0% vs. 88.0% vs. 92.0%,P>0.05). There were no statistical significances in the levels of systolic pressure,diastolic pressure,heart rate,TC,TG and serum potassium among 3 groups before treatment(P>0.05). Af-ter treatment,systolic pressure and diastolic pressure of 3 groups were significantly lower than before,with statistical significance (P<0.01);but there was no statistical significance among 3 groups(P>0.05). There were no statistical significance in heart rate, TC,TG of 3 groups before and after treatment and the level of serum potassium in benazepril group and irbesartan group (P>0.05). After treatment,the level of serum potassium in amlodipine group was significantly lower than before,with statistical signifi-cance (P<0.05). The incidence of ADR in irbesartan group was significantly lower than benazepril group and amlodipine group, with statistical significance (P<0.05);but there was no statistical significance between benazepril group and amlodipine group (P>0.05). CONCLUSIONS:The indapamide separately combined with benazepril,irbesartan or amlodipine have similar therapeu-tic efficacy for grade 2 EH,but the safety of irbesartan is better than those of benazepril and amlodipine.

Electron donatung capacuty and electron acceptung capacuty uncreased furstly and then decreased. However, the electron shuttlung capacuty uncreased persustently durung the landfull process. Proteun-luke components were the maun components of dussolved organuc matter durung the unutual landfull stage, and ut was maunly responsuble for the electron donorung capacuty and electron acceptung capacuty of DOM. Electron shuttlung capacuty resulted from humuc-luke components durung the cycluc redox process. Electron shuttlung capacuty persustently uncreased durung the landfull process based on humuc-luke components generated durung the stage.

Objecitve:To investigate effects of urotensin Ⅱ( UⅡ)/UT system on innate immune inflammatory signal pathway TLR4-IRF3 in the lipopolysaccharide (LPS)-stimulated Kupffer cells (KCs).Methods: Rat KCs were isolated and cultured.Pro-in-flammatory cytokines including IL-6,IFN-βand IFN-γwere assayed by ELISA in culture supernatant of KCs.Cell surface TLR4 were tested with flow cytometry technique.Expression of IRF3 were tested with real-time PCR and Western blot.Results: Significant increases were showed in IL-6, IFN-βand IFN-γsecretion, TLR4-expressed positive rates and IRF3 mRNA levels in KCs after stimulated by LPS,but were inhibited via urantide pretreatment.In addition,LPS induced upregulation of nuclear IRF3 protein and downregulation of cytoplasm IRF3 protein in KCs,which were blocked by urantide pretreatment.Conclusion:UⅡ/UT system mediates immune inflammatory response in part through activating TLR 4-IRF3 pathway in LPS-stimulated KCs.

Objective To investigate the effects of urotensin Ⅱ/urotensin Ⅱreceptor ( UⅡ/UT) system on the expression of inflammatory signal molecules p 38 mitogen-activated protein kinase ( p38 MAPK) and nuclear factor-κB ( NF-κB ) in lipopolysaccharide ( LPS )-stimulated Kupffer cells ( KCs ) . Methods Rat KCs were isolated and purified by means of in situ perfusion and density gradient centrifuga-tion.The isolated cells were randomly divided into six treatment groups including group 1:UⅡ(-) urantide (-)LPS(-), group 2:UⅡ(+)urantide(-)LPS(-), group 3: UⅡ(-)urantide(+)LPS(-), group 4:UⅡ(-)urantide(-)LPS(+), group 5:UⅡ(+) urantide(-) LPS(+) and group 6:UⅡ(-)urantide(+) LPS(+) .Western blot assay was performed to detect p 38 MAPK/p-p38 MAPK protein and NF-κB p65 sub-unit.The DNA-binding activity of NF-κB was tested by electrophoretic mobility shift assay (EMSA).Re-sults There was no significant difference with the expression of p 38 MAPK protein in KCs among the six groups (P>0.05).The expression of p65 protein and p-p38 MAPK and the DNA-binding activity of NF-κB were significantly enhanced in LPS-stimulated KCs from groups 4, 5 and 6 in comparison with those in group 1 (P<0.01).No significant differences with the levels of p65 protein and phosphor-p38 MAPK and the DNA-binding activity of NF-κB were observed between UⅡ/urantide-treated cells ( group 2 or group 3) and untreated cells (group 1) (all P>0.05), but that were decreased in group 6 than those in group 4 (all P<0.01).Conclusion UⅡ/UT system participated in the activation of p38 MAPK and NF-κB signaling pathways in LPS-stimulated primary Kupffer cells .

Objective To study the modulation of central amygdale (CeA)on cardiac nociception with electrical stimulation in rats.Methods The heart pain model of adult male Sprague-Dawley rats was established with intrapericardial injection of capsaicin; then the evoked electromyography (EMG ) responses in the spinotrapezius (SPT)were observed as an index.Immunohistochemical method was used to observe the expression of c-fos in CeA;The rats were divided into normal control group,intrapericardial saline injection control group,and intrapericardial capsaicin injection group. The changes of EMG responses after electrical stimulation on CeA (intensity of 30μA and 70μA)were observed separately by electrophysiology in different groups.Results① Compared with normal control group, intrapericardial capsaicin injection group had significantly increased expression of c-fos in CeA.However,c-fos expression did not differ significantly between intrapericardial saline injection group and normal control group;② After 30μA electrical stimulation on CeA,EMG response in SPT significantly decreased in intrapericardial capsaicin injection group compared with that in control group;the total discharge rate was (78.58±4.62)% of that of control group (P<0.05).After 70μA electrical stimulation on CeA, the total discharge rate was (54.89±3.98)% of that of control group (P<0.05).Conclusion CeA may be involved in cardiac nociceptive transmission in rats and has inhibitory effects on the modulation of rat cardiac nociception.

Objective:To observe the efficacy of gentle moxibustion combined with Western medicine in treating rheumatoid arthritis(RA)due to damp heat affecting bones/joints to further certificate the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy". Methods:A total of 78 patients with RA due to damp heat affecting bones/joints were divided into an observation group and a control group using the random number table method,with 39 cases in each group.The control group was treated with regular Western medicine,on the basic of which the observation group was treated with additional gentle moxibustion.Patients in the observation group received gentle moxibustion therapy once a day for 8 weeks with a one-day rest every 2 weeks.The wrist circumference,wrist pain degree,skin color and temperature of the wrist,and range of dorsiflexion motion of the wrist in the two groups of patients were compared before and after treatment under the condition of safety observed. Results:The total effective rate in the observation group was 94.9%,which was higher than the result of 79.5%in the control group(P<0.05).Among the quantitative indicators of syndrome differentiation,the wrist circumference,pain degree,skin temperature,and range of dorsiflexion motion in both groups were significantly improved(P<0.01),and the improvements were more significant in the observation group than in the control group(P<0.05).The skin color of the wrist joint was improved in both groups after treatment(P<0.05),and there was no statistical significance in comparing the improvement of skin color and the occurrence of adverse reactions between the two groups(P>0.05). Conclusion:Compared with Western medicine treatment alone,the combination of gentle moxibustion and Western medicine treatment has significantly better treatment efficacy and shares high safety,which helps to prove the scientific nature of the theory that"heat pattern can be treated by moxibustion therapy".
