Surgical resection is the treatment of choice for patients with colorectal liver metastases.The criteria for hepatic resection of colorectal liver metastases have been extended.Patients who were expected to have complete tumor resection,negative resection margin and adequate remnant liver volume could receive surgical resection.Surgical resection combined with local ablation can expand the resectability of liver metastases.There is no significant difference of long-term survival between simultaneous and staged resection for colorectal and liver tumors.Laparoscopic surgery has been proved as safe and feasible for colorectal liver metastases.The survival benefits of adjuvant chemotherapy during perioperative period is unclear,and neo-adjuvant chemotherapy might not benefit all the patients with colorectal liver metastases.

Adenosine receptors (AR) play an important role in the regulation processes for body temperature and vigilance states. During our previous studies, we noticed that aminophylline (a non-selective, blood-brain-barrier penetrably AR antagonist) could attenuate the effects of YZG-330 [(2R,3S,4R,5R)-2-(hydroxymethyl-5-(6-(((R)-1-phenylpropyl)amino)-9H-purin-9-yl)tetrahydrofuran-3, 4-diol] on lowering the body temperature. Hereby, we focused ourselves on the character of thermal regulation effect of YZG-330 in mice and tried to specify the receptor subtype via giving typical adenosine receptor antagonists. The results showed that both of the magnitude and lasting time of the effect that YZG-330 played on decreasing body temperature are in a dose-dependent manner: within the next 3 hour after intragastric administration (ig) of 0.25, 1 or 4 mg . kg-1 YZG-330, the extreme values on body temperature decreasing were (1.2 ± 0.3) °C, (3.6 ± 0.4) °C (P<0.001) and (7.4±0.5) °C (P<0.001), separately; whereas the duration that body temperature below 34 °C were 0, (10±5) and (153±4) min, separately. Adenosine A1 receptor (A1R) antagonist (DPCPX) could effectively reverse YZG-330's effect on decreasing body temperature, with intraperitoneal administration of DPCPX (5 mg . kg-1) 20 min prior than YZG-330 (4 mg.kg-1, ig), the extreme value on body temperature decreasing was (3.5 ± 0.7) °C (P<0.001), the duration that body temperature below 34 °C was (8±6) min (P<0.001). However, adenosine A2a receptor antagonist, SCH-58261, did not show any influence on the effects of YZG-330 at all. Combined with the fact that 8-SPT (a non-selective, blood-brain-barrier impenetrably AR antagonist) did not reverse the effect of YZG-330, we come to the conclusion that central-adenosine A, receptor plays a significant role on the thermal regulation effect of YZG-330.

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.

OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.
METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.
RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.
CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.
METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.
RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).
CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.
