To investigate the anti-inflammatory, analgesia and antipyretic effects of Chaige Qingre granules. Meth-ods:Kunming mice were used to make auricle swelling model by dimthylphenanthrene, and the auricle swelling degree was measured to test the anti-inflammatory effect of Chaige Qingre granules. Mice were used to make pain models by acetic acid, and the body twis-ting of the mice was counted to observe the analgesia effect of the granules. The fever model in rats was induced by yeast, and the body temperature of the rats was measured to investigate the antipyretic effects of the granules. Results:Chaige Qingre granules could relieve the auricle swelling degree significantly, and the inhibition rate was 46. 3% in the high dose group. High and middle dose groups could reduce the body twisting frequency with the inhibition rate of 51. 1% and 61. 8%, respectively. Every Chaige Qingre granules group could lower the body temperature after one hour of the administration, and the temperature could be reduced 0. 56 degrees Celsius in the high dose group. Conclusion:Chaige Qingre granules can effectively inhibit auricle swelling degree, relieve pain and reduce heat.

Objective:To study influence of renal sympathetic denervation (RDN)on cardiac function of dogs with heart failure (HF).Methods:A total of 40 dogs were randomly and equally divided into RDN group [received bilat- eral renal artery radiofrequency ablation (RFA)]and model group (only received femoral puncture).Pacemaker was implanted in every dog,and dog HF model was established using rapid right ventricular pacing.Cardiac and re-nal function indexes,BNP and sympathetic activity index levels were observed and compared between two groups be- fore RFA/sham operation,instant and four weeks after model establishment.Results:After operation four weeks, compared with model group,there were significant reductions in levels of epinephrine (E)[(362.69±42.54)ng/ml vs.(290.36±42.32)ng/ml],renin (R)[(305.46± 39.68)ng/ml vs.(230.04±32.80)ng/ml],aldosterone (AD)[(408.00±38.56)ng/ml vs.(246.00± 48.37)ng/ml],angiotensin Ⅱ (ATⅡ)[(280.00±48.08)pg/ml vs.(172.00±25.04)pg/ml]and norepinephrine (NE)[(425.65±50.54)ng/ml vs.(316.76±46.29)ng/ml]in RDN group (P<0.05 all);there were significant reductions in HR,respiratory rate (RR)and BNP level in RDN group,P<0.05 all;there were significant rise in SBP,LVEF,CO,CI,left ventricular pressure maximal rising rate (+dp/dtmax),left ventricular pressure maximal dropping rate (-dp/dtmax)and left ventricular end-systolic pressure (LVESP),and significant reductions in left ventricular end-systolic dimension (LVESd),left ventricular end-diastolic dimension (LVEDd)and left ventricular end-diastolic pressure (LVEDP)in RDN group,P<0.05 all.Conclusion:RDN can decrease renal sympathetic activity,improve heart function,inhibit myocardial remode- ling,its therapeutic effect is significant

Objective: To observe influence of long-term exercise training on carotid intima-media thickness (IMT) in patients with mild-moderate hypertension. Methods: A total of 92 patients with essential mild-moderate hypertension were randomly divided into routine treatment group (n=46) and exercise group (n=46, received exercise training based on routine treatment) according to number table. All patients were followed up for one year, and the blood pressure, carotid artery diameter and carotid IMT were measured, compared and analyzed in two groups before and after treatment. Results: There was no significant difference in systolic and diastolic blood pressure before treatment between two groups (P＞0.05). Compared with baseline value, there were significant decrease in systolic blood pressure [(176.66±l1.78)mmHg vs. (130.89±13.01)mmHg], diastolic blood pressure [(101.43±6.41)mmHg vs. (81.71±8.45)mmHg], carotid artery diameter [(6.62±0.97)mm vs. (6.22±1.01)mm] and carotid IMT [(0.98±0.12)mm vs. (0.84±0.11)mm] in exercise group after one-year training (P<0.05 all), and they were all significantly lower than those of routine treatment group (P<0.05 all ). Conclusion: Long-term exercise training can effectively control blood pressure, decrease carotid artery diameter and carotid intima-media thickness.

Objective To investigate changes of GP73 after hepatectomy and its correlations with hepatocellular carcinoma (HCC) recurrence. Methods Perioperative serum GP73 was monitored in hepatic hemangioma and HCC patients undergoing hepatectomy. Clinicopathologic features and follow-up results were collected to evaluate the relationship between serum GP73 level and patients' prognosis.Results There was no statistical difference between preoperative GP73 and postoperative GP73 in hepatic hemangioma group.While preoperative GP73 in HCC group was 9.9(3.7 - 15.8) relative unit (RU),and that on POD3 (postoperative day 3 ) was 9.1 ( 3.4 - 13.3 ) RU,on POD7 was 74.3 ( 1.7 - 9.0) RU,on POD14 was 3.3(2.1 -5.4) RU ( F =72.606,P ＜ 0.001 ).HCC recurred in 21 cases during follow-up,GP73 in recurrent cases [ 11.0 (8.4 - 13.8 ) RU ] was significantly higher than postoperative trough values while it was not different from their preoperative GP73 level [ 9.9 ( 2.9 - 15.0) RU ] ( Z =1.185,P ＞0.05). The preoperative GP73 level between recurrent subgroup and nonrecurrent subgroup was not significantly different (Z =- 1.546,P ＞ 0.05 ).Preoperative GP73 did not correlate to patients' survival.Conclusions Hepatectomy for HCC leads to a significant decrease of GP73 and postoperative HCC recurrence accompanies reelevation of GP73. GP73 could be used as a postoperative monitor for HCC recurrence.

Objective To compare the safety and efficacy between flexible ureteroscope lithtripsy (FURL) and percutaneous nephrolithotomy (PCNL) in treating the renal calculus.Methods From Jan.2012 to Oct.2013,120 male and 87 female patients with renal calculus were accepted FURL (n =108)or PCNL (n=99) in our hospital.In FURL group,108 cases were classified according to the diameter of the stone,including 33 patients with the diameter of renal stone more than 20mm (range 20-39 mm,mean 29.2±5.6 mm)and 75 patients with the diameter of renal stone less than 20 mm (range 13-19 mm,mean 16.8± 1.3 mm).In PCNL group,99 cases were also classified according to the diameter of the stone,including 51 patients with the diameter of renal stone more than 20 mm (range 20-45 mm,mean 30.4±6.6 mm)and 48 patients with the diameter of renal stone less than 20 mm (range 14-19 mm,mean 17.2±1.4mm).There were no significant differences between the groups FURL and PCNL in the stone size(P＞0.05).Demographic data,operative duration,postoperative hospital stay,complication rate,and stone-free rate were recorded and compared.Results The overall stone free rate in group FURL was significantly lower 80.6％ (87/108) than that in group PCNL 91.9％ (91/99) (P＜0.05).In those patients with the diameter of stones less than 20 mm,the stone free rate was 88.0％ (66/75) in group FURL vs 93.8％ (45/48) in group PCNL (P＞0.05).The operative time was 30-65 (mean 49.5±6.9) min and 30-65 (mean 46.9±7.2) min in FURL and PCNL group,respectively (P＞0.05).In those patients with the diameter of stones more than 20 mm,the stone free rate was 63.6％ (21/33) in group FURL,which was lower than that in group PCNL 90.2％ (46/51) (P＜0.05).The operative time was 60-115 min (85.0±16.3) min and 30-95 min (68.3± 16.7) min in FURL and PCNL group,respectively (P＜0.05).The overall complication rate was significantly lower in group FURL 2.8％ (3/108) compared to group PCNL 8.1％ (8/99) (P＜0.05).Postoperative hospitalization stay were 2-6 d (3.5±1.4) d and 3-9 d (5.8±1.9) d in FURL and PCNL group,respectively (P＜0.05).Conclusions Both PCNL and FURS are efficacy and safe surgical alteration for patients with renal calculus.As to the FURS,its merits were faster recovery,less invasiveness than those in PCNL.Therefore,it can be considered as the first-line treatment for renal calculus ＜20 mm.However,for renal calculus ≥20 mm stones,FURS is still effective.

Objective:To investigate the seroepidemiological status of Toxoplasma gondii among humans, dogs and cats and its influencing factors in three counties of Yunnan Province, and to assess the risk of dogs and cats transmitting Toxoplasma gondii to humans and causing disease and epidemics. Methods:Three pestis foci of demestic rodent in Mile City, Mang City and Lianghe County in Yunnan Province were selected as the investigation areas, and blood samples of humans, dogs and cats from 16 natural villages were collected. Serum IgG antibodies against Toxoplasma gondii were detected by indirect enzyme-linked immunosorbent assay, and the influencing factors were analyzed by logistic regression. Results:A total of 368 human serum samples, 307 dog serum samples, and 12 cat serum samples were tested. The positive rates of serum IgG antibodies against Toxoplasma gondii in humans, dogs and cats were 54.62% (201/368), 90.88% (279/307), and 91.67% (11/12), respectively. Logistic regression analysis showed that the risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans of Mang City and Lianghe County were 8.20 times ( AOR = 8.20, 95% CI: 4.38 - 15.36) and 2.22 times ( AOR = 2.22, 95% CI: 1.24 - 3.97) higher than those in Mile City, respectively, and the risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans in the age group of 30 - < 40 years old decreased by 57% compared to the age group of 30 years old ( AOR = 0.43, 95% CI: 0.19 - 0.98, P < 0.10). The risk of Toxoplasma gondii infection (serum IgG antibodies positive) in dogs of Lianghe County was 89% lower than that in Mile City ( AOR = 0.11, 95% CI: 0.02 - 0.47). The risk of Toxoplasma gondii infection(serum IgG antibodies positive) in dogs aged 2 years old and older was 2.05 times higher than that in dogs aged younger than 2 years old ( AOR = 2.05, 95% CI: 0.91 - 4.64, P < 0.10). Conclusions:The positive rates of serum IgG antibodies against Toxoplasma gondii in humans, dogs and cats in the three counties where the three pestis foci of demestic rodent are located in Yunnan Province is relatively high. The risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans, dogs is related to the region and age. The risk of dogs and cats transmitting Toxoplasma gondii to humans and other animals is relatively high. It is necessary to strengthen monitoring in key regions, carry out health education, and take corresponding health measures.
