Objective To evaluate the risk of plague occurrence via surveying and analyzing indoor rat density and flea index in natural villages having previous plague experience. Methods During August to September 2007, 30 natural villages experiencing previous plague were selected based on the surveillance data, and then all households were coded with numbers and 20 households in each village were randomly selected via computer. Cages and sticky papers were set in 600 selected households to capture rats and fleas. Rat density, flea prevalence, flea index and median were estimated. Results One hundred thirty-three Rattus flavipectus and 33 Suncus murinus were caught and averaged rat density was 2.8 rats per one hundred cage. nights (166/6000), the median was 5 rats each village. One hundred and one mice infected fleas, flea prevalence on rats was 60.8% (101/166), 296 Xenopsylla cheopis and 48 Leptopsylla segnis were collected. Rat flea index was 2.1 fleas per rat (344/166). A total of 315 dissociated flea was caught, average dissociated flea index was 0.026 fleas per sticky paper (315/11888). The median was 5.5 dissociated fleas per village. Of dissociated fleas, Ctenocephalides felis felis (205) and Xenopsylla cheopis (103) accounted for 97.8% (308/315). The proportion for species of the rat flea and the dissociated flea was different(Fisher test: P < 0.01). The rat flea was significantly associated with the rat density(r = 0.68, P < 0.01), but the dissociated flea was significantly associated with neither the rat density(r = -yield than fried wheat batter(χ2 = 5.59, P < 0.05). Conclusions In these villages having previous plague experience of Lianghe County, Rattusflavipectus was dominant species of indoor rats, Xenopsylla cheopis and Ctenocephalides felis felis were dominant species of rat flea and dissociated flea, respectively. Mengsong, Bangdu, and Tangjiatun village had potential risk of plague emergence.

Objective: To observe the influence of sot alol on the QT dispersion in patients with atrioventricular accessory pathways u nderwent radiofrequency catheter ablation (RFCA). Methods: Thirt y-six patients were divided into 2 groups by random. One was the drug group(18 cases) treated by RFCA, and sotalol 160 mg was orally administered and intracar diac electrophysiological study was performed every 30 min for 5 times. Th e other group(control group, 18 cases) only treated by RFCA.QTd,QTcd and QTLcd w ere measured before and after RFCA. Results: There was no signif icant difference with QT dispersion before and after RFCA in control group. When compared with before RFCA, QTd in patients administered sotalol was (30.9 ±14.3) ms vs (24.7±9.6) ms; QTcd(33.7±17.1) ms vs (25.2±10.1) ms; QT Lcd(30.8±14.1)ms vs (25.6±19.4) ms (P<0.05). Conclusion: Sotalol can slightly lower QT dispersion, which is beneficial for preventing malignant ventricular arrthythmia. It is safe in RFCA in pateints with accessory pathway.

At present, albumin is mainly used to prevent post-paracentesis circulatory dysfunction in patients with cirrhotic ascites, prevent renal dysfunction in patients with spontaneous peritonitis, and treat hepatorenal syndrome. Recent studies have shown that long-term albumin treatment can reduce the incidence rate of complications and improve overall prognosis in patients with cirrhotic ascites, which brings new insights into the indication for clinical application of albumin. This article reviews the clinical studies on the long-term administration of albumin in patients with cirrhotic ascites, aiming to provide evidence-based advice for further clinical research on long-term application of albumin in China.

OBJECTIVETo investigate the influence of total flavonoids of epimedium (TFE) on the streptozocin (STZ)-induced kidney injury in diabetic rats and discuss the possible mechanism.
METHODSDiabetes was produced by a single injection of streptozocin (40 mg/kg, iv) in male SD rats. The rats were randomly divided into three groups (n = 10): control group, model group and TFE group (100 mg/kg, ig). Animals were sacrificed 12 weeks later. The level of blood glucose, blood urea nitrogen (BUN) and creatinine (Cr) as well as the renal index were determined. Detect the specific biochemical of renal tissue: superoxide dismutase (SOD), malondialdehyde (MDA). Use masson staining to observe the morphology of the renal tissue. Immunohistochemistry was employed to determine the protein levels of transforming growth factor-beta1 (TGF-beta1).
RESULTSCompared to control group, the enhancement of blood glucose, renal index, BUN and Cr was found in model group, which was significantly attenuated by treatment with TFE. Meanwhile, elevated MDA level in renal tissue as well as decreased SOD activities in renal tissue were significantly remitted by TFE. Furthermore, TFE decreased the expression of TGF-beta1.
CONCLUSIONTFE can evidently relieve renal damage in rats with diabetic nephropathy induced by STZ, which might be related to antioxidation and modulating the expression of TGF-beta1 protein.

OBJECTIVETo explore the mechanism of acupoint thread embedding (ATE) in treating Alzheimer's disease (AD) by means of brain functional magnetic resonance imaging (fMRI).
METHODSTwenty-six patients with mild to moderate AD were assigned to the tested group and the control group in pairing, 13 in each group. ATE was performed in patients of the tested group at Shenmen (HT7), Fenglong (ST40), Taixi (KI3) and Zusanli (ST36) acupoints, once every month for 6 times in total; but for patients of the control group only sham operation was done at the same acupoints. The correlation between cognitive ability and fMRI were assessed by comparing the scores of Mini-Mental State Examination (MMSE) and Alzhemer's Disease Assessment Scale-Cognitive section (ADAS-Cog), monitored at two time points, namely, in one week before starting treatment and 1 week after terminating 6-month treatment. Furthermore, fMRI was detected to obtain the data of the cerebral blood oxygen content before treatment and 6 months after completing the 6-month therapeutic course. Correlation analysis was conducted on the obtained data using software SPM.
RESULTSAfter treatment, changes of MMSE score significently increased in the test group (P < 0.01) and decreased in the control group (P < 0.01), and ADAS-Cog decreased in the test group (P < 0.01) and increased in the control group (P < 0.05), showing statistical significance between the two groups (P < 0.01, P < 0.05). The activated regions related with the change of MMSE were mainly inferior frontal gyrus, middle frontal gyrus, superior frontal gyrus, transverse temporal gyrus, on the left cerebrum and superior frontal gyrus, middle frontal gyrus, precentral gyrus, hippocampal gyrus, cingulate gyrus, postcentral gyrus, paracentral lobule on the right cerebrum; those related with change of ADAS-Cog were superior frontal gyrus, middle frontal gyrus, fusiform gyrus, inferior temporal gyrus, hippocampal gyrus on the left cerebrum, and superior frontal gyrus, middle frontal gyrus, precentral gyrus, fusiform gyrus, transverse temporal gyrus, postcentral gyrus, middle occipital gyrus on the right cerebrum.
CONCLUSIONATE could improve the cognitive ability of AD patients, its possible mechanism may be through the activation on the cognition related regions of frontal, temporal lobe and marginal system, as well as those of cerebellum.
