Objective To observe the efficacy of Zhuang’s medicated thread moxibustion plus acupoint thread embedding in treating allergic rhinitis.Method By using random number table, 103 patients with allergic rhinitis were randomized into a treatment group (n=53) and a control group (n=50). The treatment group was intervened by Zhuang’s medicated thread moxibustion and acupoint thread embedding, while the control group was by acupoint thread embedding alone. The subjects were treated for 6 courses with a one-month follow-up. The therapeutic efficacies were compared between the two groups.Result The total effective rates were respectively 94.3% and 80.0% in the treatment group and control group.Conclusion Zhuang’s medicated thread moxibustion plus acupoint thread embedding has significant advantage in improving the symptoms of allergic rhinitis.

Objective To evaluate the value of dual-phase spiral CT scanning in diagnosis of small pancreatic carcinoma.Methods 21 cases with small pancreatic carcinoma (≤2 cm) underwent plain CT scan and dual-phase eahanced spiral CT including arterial phase(20~25 s after infusion)and pancreatic phase(50~60 s after infusion)with a 100 ml bolus injection of contrast material at 3~6 ml/s.CTattenuation values of tumor and normal pancreas in all scanning phase were obtained.Results The mean CT value of tumor was(42?14) HU(arterial phase)and (48?18) HU(pancreatic phase),the mean CT value of normal pancreas was (105?15) HU(arterial phase)and (86?11) HU(pancreatic phase).The dens difference of tumor-pancreas was significantly on arterial phase (69?15) HU.Conclusion The maximum dens difference of tumor-pancreas can be obtained on arterial phase CT scan,it has advantages in diagnosing pancreatic carcinoma of early period and to judge the resectionability of pancreatic carcinoma.

Objective To investigate the episodic memory monitoring in patients with white matter lesions (WML) and explore the relevance of episodic memory disorder and memory monitoring and the possible mechanism.Methods The feeling of knowing-episodic memory (FOK-EM) paradigm was adopted and subsequently administered in 30 WML patients and 30 control participants who were matched in age and educational level.Results Compared with control group (cued recall 4.37 ± 1.59;recognition 8.73 ± 1.05),the episodic memories of WML patients were significantly impaired on the cued recall performance (3.30 ± 1.51,t =2.666,P ＜ 0.05) and recognition performance (7.23 ± 0.77,t =6.306,P ＜ 0.01).Furthermore,the accuracy of FOK judgment (-0.13 ± 0.31),the correct judgment and correct recognition of FOK-EM (23.16％ ±5.96％) and the correct judgment and false recognition of FOK-EM (34.26％ ± 7.65％) in the WML patients group were significantly different compared with the control group (the accuracy of FOK judgment:0.34 ± 0.27,t =6.280,P ＜ 0.01;the correct judgment and correct recognition:35.12％ ± 6.82％,t =7.234,P ＜ 0.01;the correct judgment and false recognition:19.27％ ±6.50％,t =-8.174,P ＜ 0.01).In addition,the correct judgment and false recognition performance were positively correlated with the severity of periventricular lesions and deep white matter lesions in the WMLpatients group (r=0.716,P＜0.01;r=0.598,P＜0.01).Conclusions The WML patients demonstrated an overestimation of their recognition ability of episodic memory.Moreover,this impairment of memory monitoring was correlated with the deficit of executive function caused by the damage of the prefrontal-subcortical circuit,indicating that this mechanism could be an influential factor of episodic memory disorder in WML.

Objective To investigate the expression and relationship of livin and mutant p53 in hepatocellular carcinoma (HCC). Methods The expression of livin and mutant p53 were evaluated using the SP immunohistochemistry in 80 HCC tissue, 39 hepatic cirrhosis tissue, 33 normal tissue beside the hemangiomas of liver. Results The integrated A average results showed that the intension of positive expression of livin aligned by turns was HCC tissue (Median=5.09; P25～P75=3.06～8.28), hepatic cirrhosistissue(Median=3.05; P25～P75=2.49～4.25), normal liver tissue(Median=1.99; P25～P75=1.54～2.54) (P<0.001), respectively. It also showed that the intension of positive expression of p53 in HCC tissue (Median=43.13; P25～P75=20.41～78.53) was higher than that in hepatic cirrhosis tissue (Median=20.30;P25～P75=14.90～28.08), as well as in that of normal liver tissue (Median=15.52;P25～P75=12.81～21.80) (P <0.001), but it made no sense in statistics between hepatic cirrhosis tissue and normal tissue of liver. The expression of livin was obviously correlated with p53 in HCC tissue(r=0.241, P<0.05). Conclusion The overexpressian of livin and p53 and their positive correlation showed that livin may play a crucial role in the origin and development of HCC in coordination with p53.

K88ac-LT(B) gene derived from pQE30-K88ac-LT(B) was cloned into the expression vector pLA and then the recombinant vector was transformed into the competent cells Lactobacillus casei 525. The recombinant bacteria were grown at 37 degrees C, in MRS broth. Western blotting analysis with rabbit-anti-K88ac-LT(B) polyclonal serum indicated that the recombinant protein reacted with the specific antibodies. The results showed that the molecular weight of the recombinant protein was about 71.2 kD. The K88ac-LT(B) fusion protein on the cell surface was confirmed by immunofluorescence mciroscopy and flow cytometric analysis. In addition, the survival of recombinant Lactobacillus casei 525 was studied in imitative gastrointestinal environments such as artificial gastro fluid (pH 1.5-5.5), artificial intestinal fluid, bile(0.3-3.0 g/L). The results indicated that the recombinant strain survived well in artificial gastric fluids at pH 2.5-4.5 in 5 h. The recombinant Lactobacillus casei 525 could slowly grow in the artificial intestinal fluid for different time, and could survive in 0.3% bile.
