Objective To explore the relationship between wild rodent plague and human in wild rodent plague foci of the northwestern area in Yunnan to probe the possible transmission mechanism of wild rodent plague to human. Methods Data of component ratio of rodents and fleas was collected in different areas from 1985 - 1995. Activities and habits of residents regarding the way they keep cats and dogs and parasitic fleas and free fleas indoor were investigated, the dog serum was collected for detecting F1 antibody. Results Eothenomys miletus were main rodents in farmland and shrub, accounting for 48.00% (4753/9902) and 54.50% (4282/7857), Apodemus chevrieri were main rodents in garden, being 50.47% (1332/2639). The component ratio of Neopsylla specialis specialis was 13.31%(229/1720), 12.31%(1678/13 739) and 10.87%(957/8802) respectively in garden, farmland and shrub, higher than in indoor. The component ratio of Frantcpsylla spodix was 39.88% (686/1720), the highest in garden. Thirty-two per cent (32/100) of residents kept cats,in which 63% (20/32) with cat fleas, 68% (68/100) of villages kept dogs, in which 76%(52/68) with fleas. Eighteen parasitic fleas were caught from 43 dogs with a flea index of 0.119 and a rate for fleas of 11.63%, 7 pulex were collected from 17 indoor. Forty-three blood serum samples were obtained from dogs, among which 3 were positive blood serum. Conclusions Residents touch affected animals or media in different situations. The possibility of transmission for wild rodent plague to human exists in loci in a chain of wild rodent plague → fleas or predation → homebred animal plague (cats or dogs) →touching or respiratory → human.

It's difficult to identify Aucklandiae Radix and Vladimiriae Radix because of their similar composition. In this paper, UPLC method was used to establish their UPLC fingerprint to identify them with the mobile of acetonitrile -0. 05% phosphoric acid water solution by gradient elution at the detection wavelength of 238 nm. Clustering analysis and principal components analysis showed that Vladimiriae Radix was significantly different from Aucklandiae Radix. Eight common peaks and twelve common peaks were defined respectively in Aucklandiae Radix and Vladimiriae Radix herbs by fingerprint analysis. Six of them were identified as syringoside, chlorogenic acid, isochlorogenic acid A, isochlorogenic acid B, costunolide and dehydrocostuslactone by comparing with standard references. There are four peaks in all of Vladimiriae Radix samples and in none of Aucklandiae Radix samples. So UPLC fingerprint can be used to identify these two herbs.

[Objective]To analyze the short-term (24 h) and long-term (3 months) effects of thrombolysis in patients with acute cerebral infarction and its influencing factors.[Methods]Fifty-three patients with acute ischemic stroke,admitted to our hospital fiom January 2006 to December 201 i,were treated with urokinase (UK);the effects were observed by NIHSS and Modified Rankin Scale (mRS).Influencing factors were analyzed by Stepwise logistic regression.[Results] Twenty-eight patients had good outcome (52.8％) 24 h after thrombolytic therapy;multivariate logistic regression indicated that gender,interval between onset and receiving thrombolytic therapy,and fibrinogen level before thrombolytic therapy were the independent predictors of good outcome (P=0.007,0.017 and 0.001,respectively).Forty patients (75.4％) had good outcome 3 months after thrombolytic therapy;multivariate logistic regression indicated that the scores of NIHSS before thrombolysis and 24-h thrombolytic effect were the independent predictors of good outcome (both P=0.002).[Conclusion] Risk factors associated with short- and long-term thrombolytic effects might be different,which needs us make a difference in clinical work.

OBJECTIVETo verify the clinical efficacy of acupuncture combined with auricle cutting method for treatment of blood stasis-type psoriasis.

METHODSFifty-six cases of blood stasis-type psoriasis were randomly divided into a combined therapy group, a auricle cutting group, an acupuncture group and a control group, 14 cases in each one. Based on regular treatment of TCM decoction in four groups, the combined therapy group was treated with acupuncture and auricle cutting method, and the auricle cutting group was treated with sham-acupuncture and auricle cutting, and the acupuncture group was treated with acupuncture and sham auricle cutting, and the control group was treated with sham-acupuncture and sham auricle cutting. The acupuncture was applied at Dazhui (GV 14), Feishu (BL 13), Ganshu (BL 18) and Geshu (BL 17), etc., and manipulated with routine technique; in the sham acupuncture, the needle was inserted into dermis layer so that the needles could be swung without being dropped out. In the auricle cutting, erbeixin (P1) of unilateral auricle was selected and cut by Chan needle to perform bloodletting; in the sham auricle cutting, the neighborhood approximately 0.5 cm next to erbeixin (P) of auricle was selected as cutting area. The treatment was given once a day, seven days as a treatment session for totally two sessions. Psoriasis area and severity index (PASI) before and after treatment was observed and efficacy of each group was compared.

RESULTSThe effective rate was 57.1% (8/14) in the combined therapy group, which was superior to 14.3% (2/14) in the auricle cutting group, 7.1% (1/14) in the acupuncture group and 0.0% (0/14) in the control group (all P < 0.05). The scores of PASI were all decreased in each group after the treatment (all P < 0.05), which was the most significant in the combined therapy group (all P < 0.05). After factorial analysis, the main effect was P < 0.05 in the auricle cutting, P < 0.05 in the acupuncture and P < 0.05 in interaction effect of combined therapy.

CONCLUSIONThe scores of PASI of blood stasis-type psoriasis could be effectively reduced by acupuncture, auricle cutting method and TCM decoction, among which the interaction effect of auricle cutting and acupuncture combined with TCM decoction is the most significant.

OBJECTIVETo investigate if the interaction between TGF-beta1/Smad pathway and ERK pathway in vascular smooth muscle cells exists.

METHODSThe rat arota was removed. The primary VSMC were isolated and cultured in vitro, then the VSMC were divided into four groups: (1) control group, (2) (TGF-beta1 group, (3) ERK blocking agent group, (4) TGF-beta1 + ERK blocking agent group. The expression of Smad2/3, ERK1/2 proteins, the content of phosphorylated ERK1/2 and Smad2/3 proteins were detected by Western blot, and the expression of Smad2/3 mRNA was detected by reverse transcription-polymerase chain reaction(RT-PCR) .

RESULTS(1) In contrast to control group, the content of phosphorylated Smad2/3 and phosphorylated ERK1/2 proteins in TGF-beta1 group was increased (P < 0.05), that in ERK blocking agent group was decreased (P < 0.05). There was no difference between control group and TGF-beta1 + ERK blocking agent group. Compared with TGF-beta1 group, the contents of phosphorylated Smad2/3 and phosphorylated ERK1/2 proteins in TGF-beta1 + ERK blocking agent group was decreased (P < 0.05). There was no difference in the expression of Smad2/3 and ERK1/2 proteins among different groups. (2) There were no differences in expression of Smad2 and Smad3 mRNA among different groups.

CONCLUSION(1) TGF-beta1 can induce Smad2/3 proteins to be phosphorylated dependent on the activated ERK pathway. (2) ERK pathway does not effect the expression of Smad2/3 at the level of protein and mRNA.

OBJECTIVETo compare macroporous microcarrier Cytopore 2 and Cultispher S for their effects in microgravity culture of CL-1 cells.

METHODSCL-1 cells were cultured on Cytopore 2 and Cultispher S respectively in a rotational cell culture system (RCCS) in a volume of 50 ml. Dynamic morphological observation and cell counting and functional test were carried out during the cell culture.

RESULTSThe cells were capable of adhering to and proliferating on both of the microcarriers, reaching the growth peak on day 9 of cell culture with the maximum cell density of 4x10(6)/ml on cultispher S. Albumin was significantly higher in the supernatant of Cytopore 2 than in that of Cultispher S on days 10, 11, and 12 (P<0.05), and the urea level in the supernatant of cytopore 2 was also significantly higher on days 10 and 11 (P<0.05).

CONCLUSIONThe cells cultured on Cytopore 2, though with a smaller cell number, display better functions than those cultured on Cultispher S under RCCS conditions.
