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.

OBJECTIVE:To prepare Weiyoukang intragastric floating tablet,and to investigate in vitro releasing characteristics of it. METHODS:Weiyoukang intragastric floating tablet was prepared by full powder compression method using HPMC-K15M (framework material),octadecanol(low density bleaching promoter),sodium bicarbonate(foaming agent),PVP-K30(release reg-ulator)and magnesium stearate(lubricant)as excipients. The amounts of HPMC-K15M,octadecanol and PVP-K30 were optimized by orthogonal test and validated with 2 h,4 h and 8 h accumulative release rate of berberine (Y2 h,Y4 h,Y8 h) as index,start time (T1)and duration(T2)of floating as adjunctive index. The releasing regularity of berberine,tetrahydropalmatine,baicalin and glyc-yrrhizic acid in Coptis chinensis,Corydalis vanhus,Scatellaria baicalensis and Glycyrrhiza uralensis were measured by release model fitting method and Peppas equarion fitting method. Similar factor(f2)method was used to investigate the similarity of 4 com-ponents. RESULTS:The optimized formulation was as follows as HPMC-K15M 40 g,octadecanol 14 g,PVP-K30 2 g for 200 tab-lets. Y2 h,Y4 h and Y8 h of berberine of preparations were 31.94%,55.88%,93.34%(RSDs were 1.2%,1.5% and 1.5%,n=3),re-spectively. T1 and T2 were about 1 min and 13 h. The drug release of four ingredients all fitted Higuchi models,and were synergis-tic action of diffusion and matrix erode. The f2 were all more than 80,indicating that the release of four ingredients were similar. CONCLUSIONS:Weiyoukang intragastric floating tablet is prepared successfully,showing fast onset,long floating,sustained-re-lease and balanced release of multiple indigents.

OBJECTIVE:To screen Gongshisong's active sites for anti-sports fatigue. METHODS:Gongshisong extract was prepared with 80% ethanol extraction technology,and extracted with petroleum ether,chloroform,ethyl acetate and n-butyl alco-hol after dispersed with water to obtain the extract. 70 mice were randomly divided into blank control group(1% sodium carboxy-methylcellulose,CMC-Na),positive control group [Rhodiola wallichiana capsules,590 mg/(kg·d)],petroleum ether,chloro-form,ethyl acetate and n-butyl alcohol extracts and aqueous layer of Gongshisong groups(TS,TL,TY,TZ,TW groups). Gong-shisong extracts groups was given relevant medicine 2.5 g(crude drug)/(kg·d),ig,for consecutive 7 days. Exhaustion time of bur-den swimming test was detected. 70 mice were grouped according to above method,and the contents of liver glycogen,muscle gly-cogen and the coefficient of liver were tested in mice. 80 mice were grouped according to above method,and model group was es-tablished additionally(1% CMC-Na). The contents of lactic acid(LA),creatine kinase(CK)and urea nitrogen(BUN)in serum of mice were determined after 90 minutes of unburden swimming. RESULTS:Compared with blank control group,exhaustion time of burden swimming mice in TS,TY and TZ groups prolonged;the content of liver glycogen increased in TY,TZ and TW groups;the content of muscle glycogen increased in TS and TW groups;the contents of BUN,LA and CK in mice increased in model group (P<0.05 or P<0.01). Compared with model group,the serum content of BUN in mice decreased in TS and TY groups;that of LA in mice decreased in TZ and TW groups;that of CK in mice decreased in TS group (P<0.05 or P<0.01). CONCLUSIONS:The petroleum ether and n-butanol extract site and water layer of Gongshisong are good anti-fatigue active sites.

The teaching contents and methods were also properly worked out and good results were got.

Objective To explore the clinical value of multi-slice CT enhancement perfusion imaging (MSCTPI) in diagnosis and differential diagnosis of thyroid disease. Methods Thirty-three patients with benign thyroid diseases were enrolled in the benign group, and were divided into subgroups of nodular goiter (n=17) and thyroid adenoma (n=16), while 10 patients with thyroid carcinoma were enrolled in the malignant group. All patients underwent routine CT scanning and MSCTPI with GE LightSpeed 16-detector row CT scanner. Time-density curve (TDC) of common carotid for benign thyroid diseases and thyroid carcinoma was depicted. Perfusion parameters of blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface area product (PS) were obtained automatically. All parameters were statistically analyzed among groups. Results TDC showed single peak in common carotid artery, with small peak of speed up and slow down in benign group, while with baseline segment, up above, down segment and horizontal segment in thyroid carcinoma. There was statistical difference between benign and malignant groups in BF, BV, MTT and PS value (P=0.001, <0.001, 0.003 and <0.001, respectively). No significant difference of BV and MTT was found between subunits of benign and thyroid carcinoma (all P>0.05). BF was significantly different in benign and maligant groups (P<0.05), whereas PS in thyroid carcinoma and nodular goiter was significant different (P<0.05). No statistical difference of BF, BV, MTT and PS was detected between nodular goiter and thyroid adenoma. Conclusion MSCTPI can exactly show the blood flow features of thyroid. The analysis of BF, BV, MTT and PS is helpful for differential diagnosis between benign thyroid disease and thyroid carcinoma.

Objective To study the clinical value of DSA diagnosis and interventional therapy for non-neoplastic lower digestive tract hemorrhage. Methods Non-neoplastic lower digestive tract hemorrhage were diagnosed in 21 patients. Eight cases underwent embolization with gelfoam and 13 cases with infusion of pitressin. Results Intestinal angiodysplasia was found in 14 cases, colonic diverticulum in 2 and hemorrhage of unknown cause in 5. Hemorrhage in all patients was stopped after the interventional therapy with no serious complications. During the follow-up of 25～74 months, intestinal angiodysplasia bleeding recurred in 4 patients. Conclusions DSA is very helpful in the diagnosis of non-neoplastic lower digestive tract hemorrhage and interventional therapy is safe and effective for the stoppage of the bleeding.

The human immunodeficiency virus type 1(HIV-1)can interact with and exploit the host cellular machinery to replicate and propagate itself.Numerous studies have shown that the Mitogen-activated protein kinase(MAPK)signal pathway can positively regulate the replication of HIV-1,but exactly how each MAPK pathway affects HIV-1 infection and replication is not understood.In this study,we used the Extracellular signal-regulated kinase(ERK)pathway inhibitor,PD98059,the Jun N-terminal kinase(JNK)pathway inhibitor,SP600125,and the p38 pathway inhibitor,SB203580,to investigate the roles of these pathways in HIV-1replication.We found that application of PD98059 results in a strong VSV-G pseudotyped HIV-1NL4-3 luciferase reporter virus and HIV-1NL4-3 virus inhibition activity.In addition,SB203580 and SP600125 also elicited marked VSV-G pseudotyped HIV-1NL4-3 luciferase reporter virus inhibition activity but no HIV-1NL4-3 virus inhibition activity.We also found that SB203580 and SP600125 can enhance the HIV-1 inhibition activity of PD98059when cells were treated with all three MAPK pathway inhibitors in combination.Finally,we show that HIV-1virus inhibition activity of the MAPK pathway inhibitors was the result of the negative regulation of HIV-1 LTR promoter activity.
