Objective To compare the genetic polymorphism of 34 Yersinia pest strains of 3 kinds of ecotypes(Microtus fiscis,Qilian Mountain and Qinghai-Tibet Plateau ecotype)that isolated from the Sanjiangyuan area in Qinghai Province and Shiqu County in Sichuan Province,in order to know the ecotype relationship among the strains.Methods Thirty-four strains were amplified using the application of random amplified polymorphism DNA(RAPD)and were detected with agaroge gel electmphoresis.Results Amplified products by ngarose gel electrophoresis method showed same stripes in 31 strains,only 3 strains had slight differences.Conclusion The Microtus fuscas,Qilian Mountain and Qinghai-Tibet Plateau ecotype strains isolated from Sanjiangyuan area are genetically homologous.

Objective To analyze human plague from 2001 to 2011 in Qinghai Province and to provide a scientific basis for formulating prevention and control measures.Methods Using the descriptive epidemiological methods,epidemiological field survey data and medical records of each case of human plague were collected from 2001 to 2011 in Qinghai Province.Human plague was judged in accordance with the Plague Diagnostic Criteria (WS 279-2008).Results From 2001 to 2011,human plague was reported 14 times,with incidence of 38 cases,17 dead and death rate was 44.74％ in Qinghai Province.Epidemic areas mainly distributed in the 12 townships of 9 counties.Prevalent season was from May to October,September and October accounted for 57.89％ (22/38).There were cases of Tibetan herders and Han farmers,accounting for 76.32％ (29/38) and 23.68％ (9/38),respectively;onset age from 5 to 67 years,mainly around the age of 20-45 [68.42％ (26/38)].The most prevalent clinical types were pneumonic and septicemic plague and initial case was caused by actively contact with infected plague animals.Conclusions Qinghai human plague is mainly caused by approaching the plague infected animals,human plague in Qinghai Province is on the rise,the risk of long-distance transmission of the plague is significantly increased.

Objective: To study the pharmacodynamic differences between Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma on the treatment of adjuvant arthritis. Methods: Wistar rats were randomly divided into blank control group (normal saline), model control group (normal saline), Tripterygium wilfordii glycosides (TWG) group (9.45 mg/kg), low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (crude Atractylodis Rhizoma) group, low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (stir-baked Atractylodis Rhizoma with bran) group. Except the blank control group, the other groups were modeled to adjuvant arthritis with complete Freund's. Paw edema value, spleen and thoracic gland indexes, serum interleukin-1β (IL-1β), and nitric oxide (NO) were observed. Results: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma could inhibit paw edema, decrease spleen index, advance the thoracic gland index, and decrease IL-1β and NO. The Simiao Pills with crude Atractylodis Rhizoma showed better effects. Conclusion: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma show a certain therapeutic effect on adjuvant arthritis, but the crude Atractylodis Rhizoma is in favor of the efficacy of Simiao Pills.

Objective To discuss the clinical features,diagnosis and operative treatment in Crohn disease(CD)characterized by acute abdomen.Method The clinical data of 26 CD cases testified by pathology after emergency operations from April 1997 to February 2009 were retrospectively analyzed.Results In 26 cases of acute abdomen,17 cases characterized by mechanical obstruction,6 cases characterized by peritonitis,3 cases characterized by hemorrhage of digestive tract.Eight cases(30.8%)were diagnosed before operation,and 13 cases(50.0%)were diagnosed during operation,totally 80.8%(21/26).All patients received surgical operations as following:resection and anastomosis in 21 eases,resection and fistulation in 4 cases,ileotransverso-stomy in 1 case.Two cases died after operation,and others discharged including 1 case received second operation within 5 days.Conclusion It is difficult to be diagnosed before operation when CD characterized by acute abdomen,and appropriate emergency operations are needed according to the particular cases.

Objective To evaluate the efficacy and safety of disodium cantharidinate injection combined with transcatheter arterial chemoembolization(TACE) compared with TCAE alone in the treatment of hepatocellular carcinoma(HCC) by meta-analysis.Methods Databases of Pubmed, CNKI,Wangfang and VIP were searched electronically, and the randomized controlled trials about disodium cantharidinate injection combined with TACE in the treatment of HCC were included.Meta-analyses were conducted after the quality of the included studies was assessed.Results Seven eligible studies that included a total of 562 HCC patients were identified in the present meta-analysis.The combined results showed that disodium cantharidinate injection combined with TACE in the treatment of HCC, compared with TACE alone, could increase effective rate ( RR =1.31, 95%CI 1.10-1.56) and clinical benefit rate (RR =1.20, 95%CI 1.04 -1.39), improve the life quality (RR =1.60, 95%CI 1.26 -2.03) and improved the 1, 2 year survival (RR =1.57 with 95%CI 1.28 -1.93 and RR =2.08 with 95%CI 1.46 -2.97, respectively).Conclusion Meta-analysis indicates that the efficacy of disodium cantharidinate injection combined with TACE is superior to TACE alone for the patients with HCC.

Objective To explore the feasibility of dual-source CT virtual scan replace conventional scan in the CT peritoneography. Methods Prospective enrolled 29 cases who accepted peritoneal dialysis (PD) treatment and were highly suspected with PD-related complications. The patients were firstly underwent CT conventional in the fasting state by applied the dual-source CT (single energy pattern), and then 2 L dialysate which mixed with contrast medium was infused into peritoneal cavity, and the CT scan was performed again after 30 min (dual-energy pattern). Scaning data were processed by virtual post-processing software to obtain virtual CT scan imaging. Subjective evaluation (including lesions and image quality score) and objective evaluation (including the CT value, noise and signal to noise ratio) were performed on the conventional scan and virtual scan, and recorded the radiation dose. Wilcoxon test was used to analyse the differences of lesions revealing and image quality score of conventional scan imaging and virtual scan imaging, and paired t test was applied to compare the differences of radiation dose and the other quality objective evaluation index. Results There was no significant difference between conventional CT scan and virtual CT scan in the cyst, calcification, calculus, hematoma and catheterization (P>0.05). The image quality score of conventional CT scan and virtual CT scan was 5.0±0.0 and 4.9±0.4, and there was no significant difference (Z=-1.6,P=0.10). There was no statistically significant difference in CT value of muscle, kidney, subcutaneous fat, urine in bladder and intraperitoneal fluid between the two groups (P>0.05), and the CT value of liver in the virtual CT scan was higher than that in the conventional CT scan (P<0.05), but the value of bone in the virtual CT scan was lower than that in the conventional CT (P<0.05). The noise of conventional CT was significant higher than that of invirtual CT, but the SNR was significant lower than virtual CT scan (P<0.05). The effective radiation dose in the conventional CT scan and virtual CT scan were(9.6±1.4)and(15.9±4.9)mSv, and showed significant difference. Furthermore, the effective radiation dose decreased by 39.6%(6.3/15.9). Conclusion Dual-energy CT scan can replace conventional CT scan in the CT peritoneography, which can guarantee the accuracy of diagnosis and reduce radiation dose.

With the increasing frequency of international exchanges and cooperations,students from foreign countries,such as India and Pakistan,have come to our country for their higher degree education.We studied retrospectively and explored the teaching methods of Histology in English,and further provide our thoughts and viewpoints on improving the teaching qualities of foreign students.
