Journal of Acupuncture and Tuina Science 2021;19(4):321-328
Objective: By sorting and analyzing pertinent modern studies targeting auricular point therapy treating primary insomnia (PI), to summarize the point selection rules and clinical efficacy of using auricular points alone or combining it with other therapies in treating PI. Methods: A search on China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed, Springer and Ovid were conducted from January 1, 1998 till January 31, 2020. Point selection, diagnostic criteria and Pittsburgh sleep quality index (PSQI) in the eligible studies were analyzed and summarized. Results: The difference in PSQI before and after using auricular point therapy alone was more significant than that of using Chinese medication alone (P<0.05), but less significant than that of combining auricular point therapy and acupuncture-moxibustion and Chinese therapeutic massage (tuina) (P<0.05). In the included studies, Shenmen (TF4) was the most commonly used (370 times), followed by Heart (CO15), which was 344 times, and Subcortex (AT4), which was 325 times. In terms of auricular points distribution, points in the auricular concha were the most commonly used (1500 times), followed by those in the antitragus (474 times) and triangular fossa (387 times). Correlation analysis showed that Shenmen (TF4) and Liver (CO12), Sympathetic (AH6a) and Heart (CO15) were used together more often, followed by Shenmen (TF4), Liver (CO12), Spleen (CO13), Kidney (CO10) and Subcortex (AT4), and then Shenmen (TF4), Liver (CO12), Sympathetic (AH6a), Subcortex (AT4) and Heart (CO15). Cluster analysis showed that the auricular points used for PI can be divided into 6 clusters in 2 major groups. One group was Heart (CO15), Subcortex (AT4), Shenmen (TF4), Sympathetic (AH6a), Spleen (CO13), Kidney (CO10), Liver (CO12) and Endocrine (CO18); the other was Occiput (AT3), Stomach (CO4), Pancrease-gallbladder (CO11), Chuiqian (LO4), Small Intestine (CO6), Central Rim (AT2,3,4i) and Sanjiao (CO17). In terms of patterns in traditional Chinese medicine, the pattern of dual deficiency of heart and spleen accounted for the largest proportion in the studies of using auricular points alone or combining it with other treatments to treatment PI, and then it was the pattern of liver depression transforming into fire. Conclusion: In treatment of PI with auricular points alone or combo therapy involving auricular points, Shenmen (TF4) was commonly used, and the commonly used point group consisted of Shenmen (TF4), Liver (CO12), Sympathetic (AH6a) and Heart (CO15). Auricular point therapy can be taken as a complementary therapy in treating PI.

BACKGROUND:Researches on attentional blink (AB) emphasized the importance of the distractors directly following targets and that of the leading distractors in rapid serial visual presentation (RSVP) streams in the production of the AB,but little has been mentioned about the subsequent distractors after the second target (except the one in direct succession to it).OBJECTIVE: To investigate the effect of subsequent distractors in RSVP stream on AB after the second target (T2).DESIGN: A randomized and controlled study.SETTING: Laboratory of Cognitive Science, South-central University for Nationalities.PARTICIPANTS: Twenty-five undergraduates aging 18-21 years with the mean age of 19 years were selected from South-central University for Nationalities. All undergraduates participated in the experiment did not have nervous mental diseases but had normal sight or corrected visual acuity; meanwhile, all of them provided the confirmed consent. The subjects were divided into experimental group (n =14) and control group (n =11). There were no significant differences between the two groups in age and sex (P > 0.05).METHODS: The experiment was carried out in the Laboratory of Cognitive Science, South-central University for Nationalities from January to April 2007. ① Experimental intervention: The stimuli were RSVP streams consisted of digit distractors and two letter targets (T1 and T2). ② Experimental grouping: The experimental group participated in the omitted condition and the control group participated in the preserved condition. ③ Experimental analysis: One-way ANOVA was used to evaluate the data for statistically significant difference in the same group, and t test was used to compare data between two groups.MAIN OUTCOME MEASURES: Report accuracy of T1 and T2.RESULTS: A total of 25 subjects were involved in the final analysis. ① Report accuracy in the preserved condition:Correct identification of the first target, averaged across all lags, was 94.6%. The percentages of correct identification of the second target as a function of lag was high at Lag1 (92.7%), dropped dramatically at Lag2 (79.8%), then kept improving with increase of lag, revealing a significant effect of lag [F(4,40) = 10.98, P< 0.01]. ② Report accuracy in the omitted condition: Correct identification of the first target T1, averaged across all lags, was 96.2%. The percentages of correct identification of the second target as a function of lag, T2 report was high at Lag1 (94.4%), decreased at Lag2(84.4%), then improved at Lag3 (91.1%), but dropped remarkably again at Lag5 and Lag7 (44.9 vs. 43.9%), revealing a significant effect of lag [F (4,52) = 224.0, P < 0.01]. ③ Comparison of the results in two conditions: T2 accuracy in the omitted condition was significantly lower than that in the preserved condition at Lag5 [t (23)=34.44, P < 0.01], and Lag7 [t (23)=42.56, P < 0.01], but did not differ from each other at Lag1 [t (23)=0.65, P > 0.05], at Lag2 [t (23)=1.04, P >0.05], and at Lag3 [t (23)=0.64, P > 0.05].CONCLUSION: The absence of subsequent distractors after T2 can introduce a bias on the attentional status of subjects to bring the T2 accuracy down to unusual low level at long lags.

Objective To investigate the feasibility of laparoscopic extirpation for mammary multiple fibroadenoma. Methods A total of 12 patients with multiple fibroadenoma that were diagnosed by ultrasonography and fine needle aspiration were enrolled in this study. Through an axillary small incision, the air was inflated into the retromammary space, which had been obtusely separated to build a surgical space. Then, 58 fibroadenomas were resected under a laparoscope. Frozen-section examination was carried out during the operation. Results All the masses of the 12 patients were laparoscopically extirpated successfully, without operative complications. The operation time was 40-150 minutes with a mean of 80 minutes. One month after the operation, the shape of the breast looked well and the sensation of the nipple remained normal. During a 1- to 36-month follow-up (mean 18.5 months), none of the patients had scars on the breast or tumor recurrence. All of them were satisfied with the cosmetic results. Conclusion Laparoscopic extirpation of mammary multiple fibroadenoma through the retromammary space is safe and feasible.

Using gene fusion technology, polypeptide fusion tags can be engineered into target proteins at the genetic level.The resultant recombinant proteins may possess the biochemical properties of the imported fusion tags.Therefore, it is possible to take advantage of fusion tags to improve and evaluate protein expression, to detect and track protein targets, and to purify and characterize proteins.However, it is necessary to eliminate any influence of the fusion tag in structural characterization experiments or in isolating pharmaceutical proteins.Scientists must therefore remove fusion tags prior to structural and functional analyses when fusion tags are suspected of interfering with the biological activity of a protein or influencing its behavior.The fusion tag can be removed by several methods including harsh chemical treatment, mild enzymatic cleavage by endoprotease or exoprotease, and intein-mediated self-cleavage.Here the literature is reviewed in relation to principles, applications, and approaches of each method.

Hereditary disease, especially monogenic disease is one of the major causes for malformation and disability of children. Most hereditary diseases have no effective therapy besides clinical symptomatic treatment. Biological techniques targeting casual genes or related signaling genes, such as transgenic, RNA interfere, genome editing, have been successfully applied in treating some hereditary diseases. However, most biological, treatments were carried out in animals, further confirmation of the effectiveness and safety of these therapies, and development of more therapeutic approaches based on mechanisms are needed before clinical trials.

In the presence of ZnO nanoparticles ( ZnO NPs ) and EDTA, luminol could produce strong chemiluminescence ( CL) without any oxidant. Therefore, a new CL system was established based on luminol-EDTA-ZnO NPs. As caffeic acid could strongly inhibit the CL, a flow injection CL method for the determination of caffeic acid was proposed. Under the optimized conditions, the relative CL intensity was linear over the logarithm of concentration of caffeic acid ranging from 1 . 0í10-7 mol/L to 1 . 0í10-5 mol/L with the detection limit of 1. 8í10-8 mol/L (3σ). The relative standard deviation (RSD) for the determination of 4 . 0í10-7 mol/L caffeic acid was 3 . 5% ( n=11 ) . The new method was successfully applied to determine the caffeic acid content in the tablets with the recoveries in the range of 97%-101%.

ObjectiveTo observe the healing effect of deep partial thickness burns by the injecting of breviscapine and discuss the possible mechanisms. Methods A rat model of deep partial thickness burns was designed,and was injected with breviscapine.The control group was injected with normal saline.The healing time of burn wound of the two groups was recorded,respectively.Seven days later,the tissues of bum wound of each group were extracted and the contents of hydroxyproline,collagenase-1,nitrogen monoxidum,erythrocuprein,and malonaldehyde that were contained in each extracts were measured.The results of each group were statistically analyzed.ResultsThe healing time of burn wound of the experimental group was [ ( 12 ± 1.428 ) days ],which was significantly shorter than the control group [ ( 14.75 ±1.291 )days] ( P <0.05).The contents of hydroxyproline[ (3.17 ± 1.136) mg/g],collagenase-1 [ ( 1.28± 0.651 ) mg/g ],nitrogen monoxidum [ ( 2.62 ± 0.30 ) μmol/gprot ],and erythrocuprein [ ( 221.25 ±25.94) U/mgprot ] in the experimental group were all higher than the control group [ (7.32 ± 2.173 )mg/g,(5.38 ±0.363) mg/g,(7.28 ± 0.40) μmol/gprot,(296.36 ± 29.29) U/mgprot ] ( P < 0.05 or P <0.01 ).However,the content of malonaldehyde [ (6.36 ± 0.93 ) nmol/mgprot ] was lower than the control group [ ( 1.25 ± 0.59) nmoL/mgprot ] ( P < 0.05 ).ConclusionsThe breviscapine injection can decurtate the healing time of deep partial thickness bums and it may be related to the extension of blood vessel,improvement of microcirculation,elimination of oxygen free radical,and degradation of lipid peroxidation.

Objective To analyze the treatment effect of deep venous thrombosis (DVT) in acute pulmonary thromboembolism (PTE) with thrombolytic and anticoagulant therapy. Methods Post hoc analysis of data from a prospective multicenter randomized control thrombolytic and anticoagulant trial of 516 patients with acute symptomatic PTE from June 2002 to December 2004. Thrombolytic therapy was performed in patients with massive and sub-massive PTE and anticoagulant therapy was given in patients with non-massive PTE. A total of 362 patients that accepted compression uhrasonography (CUS) before and 14 days after treatment constituted this study. Results The ratio of detected DVT by CUS 14 days after treatment was reduction than that before treatment ( x2 = 22. 667, P < 0. 001 ), but 11.6% patients had new or recurrent DVT. The rates of recanalization in thrombolysis group and anticoagulant group were 56. 5% and 47. 8% respectively (x2 = 1. 435 ,P =0. 231 ). The results after three months follow up showed not recovery in 30. 4% DVT patients and new or recurrent DVT in 10. 4% patients. Conclusions The normalization rate of DVT is low during 14 days treatment, and recurrence rate is high. Thrombolysis has no better rate of recanalization than anticoagulant. The prognosis of DVT hasn't improved significantly during short term treatment.
