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 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.

[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 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 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.

Objective:To observe the clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH).Methods:A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method,with 59 cases in each group.The observation group was intervened by balance-impact tuina therapy,while the control group was intervened by conventional tuina therapy,both for consecutive two weeks.The scores of visual analog scale (VAS),Oswestry disability index (ODI),quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment.The data were statistically analyzed.Results:After intervention,the total effective rate was 96.6％ in the observation group versus 91.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The VAS and ODI scores declined significantly after treatment in both groups (all P＜0.05),and the observation group was markedly lower than the control group (P＜0.05,P＜0.01).The QOL-C30 score increased significantly after treatment in both groups (both P＜0.05),and the observation group was markedly higher than the control group (P＜0.05).The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P＜0.05,P＜0.01).Conclusion:Compared with the conventional tuina therapy,the balance-impact tuina therapy shows advantage in lessening pain,improving the function and enhancing the quality of life in the treatment of LIDH,and it has a lower relapse rate.Thus,this therapy is worth promoting in clinic.

OBJECTIVETo evaluate the clinical efficiency of circumferential ablation around orifice of pulmonary vein by radiofrequency (RF) energy in the cure of chronic atrial fibrillation (AF) in patients with rheumatic valvular disease.

METHODSRadiofrequency catheter ablation was performed in 20 patients with rheumatic valvular disease and chronic AF who underwent heart valve surgery. The ablation temperature was 50 - 60 degrees C and the linear RF ablations were performed encircling the four openings of pulmonary veins and connecting the posterior mitral annulus with the probe made by ourselves especially for this ablative procedure. And amiodarone was given from the third day before the surgery and lasted for 3 months thereafter. Twenty patients with chronic AF who underwent valvular surgery but refused RF ablation were considered as the control group.

RESULTSSinus rhythm (SR) restored in 19 patients either spontaneously or after intraoperative direct current cardioversion, immediately after the operation, as compared with 16 patients in the control group. During the follow-up (24 +/- 3) months, 16 of 20 patients (80%) remained in sinus rhythm in patients received ablation, but in control group, SR was presented in only 7 of 20 patients (35%).

CONCLUSIONSCircumferential ablation around orifice of pulmonary vein by RF energy is safe and effective in restoration and maintenance of SR in patients with rheumatic valvular disease and chronic AF.

OBJECTIVESTo explore the clinical, pathological features and prognosis of patients with chromophobe renal cell carcinoma.

METHODSFrom January 1998 to January 2008, clinical data of 29 patients with chromophobe renal cell carcinoma including clinical manifestations, imaging examinations, treatment models, pTNM stages and follow-up results, were summarized to investigate its features and prognosis.

RESULTSAll cases had no obvious clinical and preoperative imaging presentation. There were 23 patients underwent radical nephrectomy, and 6 cases underwent nephron sparing surgery. Postoperative pathological findings confirmed the diagnosis of chromophobe renal cell carcinoma. Macroscopically, the cut surface of the tumors were generally beige in color. Histologically, it showed polygonal chromophobe cells and small round eosinophilic cells with eccentric hyaline degeneration. These tumor cells had a clear and sharp membrane, lightly stained abundant cytoplasm with a fine reticular translucent pattern and irregular nuclei. And a perinuclear halo was often seen in these cells. Histochemically, the tumor cells generally show a diffuse and strong reaction for CK-8 with a negative expression of Vimentin. The pTNM stages of the tumor were as follows, pT1N0M0 in 11 cases, pT2N0M0 in 8 cases, pT3aN0M0 in 5 cases, pT1N1M0 in 3 cases, pT2N1M0 in 2 cases. Twenty-six cases of patients were followed up (24 to 144 months, with an average of 90 months), 3 cases died of cardio-cerebrovascular disease, and local recurrence involved in 6 cases with reoperation in 4 cases, as well as distant metastasis in 1 case. Twenty-one cases survived with tumor-free. The statistical results indicated that the survival rates of the patients with chromophobe renal cell carcinoma in five years and ten years were 83.9%, 77.9%, respectively, compared with renal cell carcinoma of the same stage 63.8% and 49.9% at the same periods, and there is no difference in the survival rate of five years (P > 0.05) but significant difference in that of ten years (P < 0.01).

CONCLUSIONSChromophobe renal cell carcinoma is a morphologically uncommon subtype of renal cell carcinoma with the good prognosis. Definite diagnosis depends on its typical pathological feature. Radical nephrectomy is the first choice for the treatment of chromophobe renal cell carcinoma.
