OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.
METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.
RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).
CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

Objective:To find absorbable adhesives with suitable bonding properties for the absorbable polylactic acid root canal post. To test and compare the bond strengths of absorbable polylactic acid root canal post with three different adhesives. Methods:The absorbable polylactic acid root canal posts were used to restore the extracted teeth, using 3 different adhesives: cyanoacrylates, fibrin sealant and glass ionomer cement. The teeth were prepared into slices for micro-push-out test. The bond strength was statistically analyzed using ANOVA. The specimens were examined using microscope and the failure mode was divided into four categories:cohesive failure between absorbable polylactic acid root canal posts and adhesives, cohesive failure between dentin and adhesives, failure within the adhesives and failure within the absorbable polylactic acid root canal posts. Results:The bond strength of cyanoacrylates [(16. 83 ± 6. 97) MPa] and glass ionomer cement [(12. 10 ± 5. 09) MPa] were significantly higher than fibrin sealant [ ( 1 . 17 ± 0 . 50 ) MPa ] , P <0 . 001 . There was no significant difference between cyanoacrylates and glass ionomer cement (P =0. 156). In the group of cyanoacrylates, the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 25 . 0%, the cohe-sive failure between the dentin and the adhesives was 16. 7%, the failure within the adhesives was 33. 3%, and the failure within the absorbable polylactic acid root canal posts was 25 . 0%. In the group of fibrin sealant , the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives was 66 . 7%, the cohesive failure between the dentin and the adhesives was 22 . 2%, the failure within the ad-hesives was 11. 1%. In the group of glass ionomer cement, the cohesive failure between the absorbablepolylactic acid root canal posts and the adhesives was 87. 5%, the failure within the adhesives was 12. 5%. The major failure mode in fibrin sealant and glass ionomer cement was the cohesive failure between the absorbable polylactic acid root canal posts and the adhesives. No major failure modes were found in the group of cyanoacrylates. Conclusion:The bond strength of fibrin sealant is low, which cannot meet the requirement of clinical use. The bond strengths of cyanoacrylates and glass ionomer cement are suitable for clinical use. The cyanoacrylates are a kind of absorbable adhesive which has suitable bonding proper-ties for the absorbable polylactic acid root canal post.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. This review, we summarized the research findings over the past years, and discussed the nano-reinforcing materials used to prepare molecular imprinting of proteins and the perspective of these nano-reinforcing materials.

Objective To investigate the application of colostomy care products in managing the leakage around PTCD drainage tube, and to discuss its clinical effect. Methods A total of 56 patients with malignant obstructive jaundice, who had received PTCD and suffered from postoperative leakage around PTCD drainage tube, were randomly and equally divided into the study group (n=28) and the control group (n=28). The colostomy care powder, the skin protective film and the colostomy bag were used for the patients of the study group, while iodophors, sterile gauze and mupirocin ointment were employed for the patients of the control group. The incidence of irritant dermatitis around PTCD drainage tube, the degree of comfort to the indwelling tube judged by the patient, and the nursing workload for PTCD drainage tube were determined, and the results were compared between the two groups. Results The incidence of irritant dermatitis around PTCD drainage tube in the study group was obviously lower than that in the control group. And the degree of comfort to the indwelling tube judged by the patient in the study group was much higher than that in the control group. The differences between the two groups were statistically significant (P<0.05). Conclusion Combination use of colostomy care powder, skin protective film and colostomy bag can effectively reduce the incidence of irritant dermatitis around PTCD drainage tube and improve the patient’s condition. Therefore, this method is worthy of popularization in clinical practice.

Objective To investigate the regulating effects of Zuogui Jiangtang Jieyu Formula (ZJJF) on Bcl-2, Bax and Caspase-8 in hippocampus neuron damage in diabetes mellitus with depression (DD). Methods Hippocampal neurons from 18 d pregnant rats were primitively cultivated, and then combination of glucose and corticosterone was used to construct DD simulation environment. Cultivated hippocampal neurons were randomly divided into normal group, blank serum group, model group, positive medicine (metformin+fluoxetine) serum group and to-be-tested medicine (ZJJF) serum group. Normal group and model group were given same amount culture medium, while other group were given relevant amont of 10% medicine serum or blank serum. After modeling intervention for 18 h,Hoechst staining was used to detect the apoptosis of hippocampal neurons. The expression of Bcl-2, Bax and Caspase-8 was detected by high content analysis. Results Compared with the control group, hippocampal neuron dendrites ruptured or decreased, neural network connection decreased, cells showed significant staining, broken, uneven distribution of light spots, the expression of Bcl-2 protein decreased significantly (P<0.05), but Bax and Caspase-8 were increased (P<0.05, P<0.01). Compared with the model group, hippocampal neurons in both positive medicine serum group and ZJJF serum group gradually recovered. Hoechst staining showed that the nuclei were significantly homogenized, local highlights were significantly reduced, Bcl-2 protein expression levels were significantly increased (P<0.05, P<0.01), while Bax and Caspase-8 were obviously down-regulated (P<0.05, P<0.01). Conclusion ZJJF has protective effects on hippocampal neurons in DD of model rats, and its mechanism is related to regulating the expression of Bcl-2, Bax and Caspase-8 in hippocampus neuron.
