Objective To explore the value of strain rate imaging (SRI) technology in the diagnosis of hypertension patient with re-gional left ventricular early diastolic dysfunction. Methods 50 essential hypertension patients were divided into hypertension Group Ⅰ and Group Ⅱ, including 31 patients with normal left ventricular and 19 patients with left ventricular hypertrophy. 25 healthy people were used as the control group. SRI was done in the six different basal myocardial segments and the parameters of SRI were compared with that of Doppler tissue imaging (DTI) and pulse Doppler (PW). Results In the hypertension group, SRe of the six different basal myocardial segments was lower than that in the control group (P<0.05), but (SRa) of hypertension group was higher (P<0.05). SRe was negatively correlated with the patients'illness development (r=-0.89, P<0.05), but SRa was positively correlated (r=0.97, P<0.05). And the SRe/SRa<1 detection rate of Group Ⅱ was higher than that in Group Ⅰ, and the ratio in the control group was lowest(P<0.05). Total detection rate of SRI (88%) was higher than Em/Am <1 of DTI (79.67%) and E/A < 1 of PW(60%), and these changes were more obvious in Group Ⅰ. SRI was higher than DTT and PW (P<0.05). Conclusion Compared with traditional technology and methods, SRI could pro-vide more accurate diagnoses to hypertension patient with regional left ventricular early diastolic dysfunction.

Objective: To observe the effect of moxibustion on acupoints Zusanli (ST 36) and Liangmen (ST 31) on cell proliferation and cell apoptosis of gastric mucosa in rats with stress ulcer, investigatethe mechanism of moxibustion in promoting the repair of gastric mucosal injury at cellular and molecular levels. Methods: Sixty healthy Sprague-Dawley rats were randomly divided into four groups: the restraint control group, model group, moxibustion on acupoints group and moxibustion on non-acupoints group. Water immersion and restraint stress (WRS) was used to copy the stress ulcer model of rats, radio-immunoassay was used to detect the content of transforming growth factor (TGF-α), and S-P immunohistochemical assay was adopted to determine the HSP70 expression, the proliferating cell nuclear antigen (PCNA) and cell apoptosis index in gastric mucosa. Results: For the WRS-induced gastric ulcer model of rat,the gastric mucosal injury (gastric ulcer index, UI) was increased, the content of TGF-α was decreased, PCNA was also decreased, HSP70 expression and cell apoptosis index were all increased (P<0.01). Moxibustion on acupoints Zusanli (ST 36) and Liangrnen (ST 31) could decrease UI, increase the content of TGF-α, promote the expression of PCNA and HSP70,decrease cell apoptosis index in gastric mucosa, with significant differences when compared with the model group and control group (P<0.01). Conclusions: Moxibustion on acupoints Zusanli (ST 36) and Liangmen (ST 31) had protective effect on the gastric mucosa of stress ulcer, its mechanism may be promoting the TGF-α synthesis, stimulating cell proliferation in gastric mucosa and inhibiting cell apoptosis in gastric mucosa, and this process is related to the moxibustion-induced HSP70 expression.

Objective To evaluate the nephrotoxicity induced by radiographic contrast media with different osmolality in rats with hypercholesterolemia, and to explore the protective effect of pentoxifylline. Methods Forty-eight healthy SD male rats were randomly divided into normal dietary group (NN, n =8) and high cholesterol supplemented dietary group (H, 4% cholesterol and 1% cholic acid, n=40). At the end of 8th week, the rats with high cholesterol diet were randomly divided into five subgroups (n=8, respectively): high cholesterol diet group(HN), high cholesterol plus iso-osmolar contrast media (iodixanol, IOCM) group (HI), high cholesterol plus low-osmolar contrast media (iohexle, LOCM) group (HL), high cholesterol diet plus high-osmolar contrast media (diatrizoate, HOCM) group (HH) and high cholesterol plus HOCM plus pentoxifylline group (HHP). Forty-eight hours after contrast media injection, the rats were executed and blood samples were prepared to determine total cholesterol, triglyceride, serum creatinine, creatinine clearance(Ccr), fractional excretion of sodium and potassium(FeNa, FeK), and angtension Ⅱ (Ang Ⅱ) levels. The renal injury was assessed by HE staining and TUNEL staining, respectively. The expression of NF-κB protein in the renal tissue was detected by using immunohistocbemical method. Results An increase of cholesterol was observed in all the rats with high cholesterol diet. Scr, FeNa%, FeK% and Ang Ⅱ levels of rats in HH group were obviously higher than those in HL and HI groups respectively. Ccr in HH group [(0.11±0.02) ml·min-1·(100 g)-1] was significantly lower than that in HHP group [(0.43±0.03) ml·min-1·(100 g)-1], HL group [(0.25±0.02) ml·min-1·(100 g)-1] or HI group [(0.27±0.03) ml·min-1,(100 g)-1] (P<0.05). TUNEL staining showed that the pewentage of apoptotic cells in HH group [(89.60±6.40)% ] was higher than that of the other groups [NN (2.40±0.77)%, HN (5.60±1.08)%, HHP (8.91±1.44)%, HL (63.34±11.97)% and HI (61.50±9.40)%]. Immunohistochemistry staining showed that the average gray value of NF-κB positive cells in HH group decreased (P<0.05). There were no significant differences of all indices between HL and HI groups (P0.05). Conclusions Contrast media can cause kidney injuries in the rats with hypercholesterolemia. PTX can protect the renal tissue from nephrotoxicity induced by HOCM in hypercholesterolemia.
