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.

The hydride generation technique was used to determination of germanium in the presence of L-cysteine.The GeH4 was absorbed and coloured by a mixed solution of 2-(5-NO2-2-pyridylazo)-5-diethylaminophenyl(5-NO2-PADAP),NaClO and (CH2)6NH+.The maximum absorption of the colour complex was at 564nm.Its apparent molar absorption coefficient was 1.84×105L·mol-1·cm-1.Beer＇s law was obeyed for 0～500μg/L germanium.The recoveries of spiked samples were in the range of 89%～97%,while the relative standard deviation was less than 6.3%.This method is sensitive,simple and reproducible.The method has been applied to the determination of Ge in the chinese medicine with satisfactory result.

Objective To investigate the immunophenotype characteristics,the clinical significance of CD28 and International staging system in multiple myeloma (MM).Methods BM aspirate samples from 49 newly diagnosed MM patients and 22 patients after treatment were assessed using 4 color flow cytometric analyses.These MM patients were classified according to International staging system and the consolidated risk staging system,and the survival rates and treatment efficiency of 2 staging system were compared.Results The higher stage,according to the international staging system,the lower treatment efficiency [the efficacy rates of Ⅰ,Ⅱ,Ⅲ stage were 83.3 ％ (4/6),38.5 ％ (5/13),38.5 ％ (5/13),36.5 ％ (19/52)](x2 =4.235,P =0.04),and the survival and progression-free survival time of high-risk group were significantly shortened (P ＜ 0.05).The rate of CD28 abnormal expression was no significant different between the initial and the treatment group [27 (55.1％),14 (63.4 ％)],also similar in the impact of survival and progression-free survival time (P ＞ 0.05).According to the consolidated risk staging system,the treatment efficiency,the survival and progression-free survival time of high-risk group were significantly shortened than the low ones (P =0.040).Conclusions The patients with higher ISS stage,abnormal expression of CD28,and high-risk group have poor prognosis.

Objective To investigate the effect of mesenchymal stem cell(MSC) on the balance of Th1/ Th2 with different stimulations.Methods To inoculate MSC in 24-well tissue culture plates.after 3 days, added T lymphocytes co-stimulated by PMA and Ionomycin,or the MSC were added to the two-way mixed lymphocyte culture according to different proportion.The subsets and cytokines of T lymphocytes were analyzed by flow cytomety.Results Differentiation into Th1 of T lymphocytes activated by co-stimulation can be inhibited MSC;In MLC,CD8~+T cell subsets and Th1 were evidently decreased.But Th2 cells were slightly increased.Conclusion MSC can significantly suppress CD8~(+)T cell,Th1,increase Th2.MSC has potentialities of alleviating acute graft-versus-host disease(aGVHD) and maintaining graft versus leukemia(GVL).

Objective:To establish the sensitive,specific,stable and convenient sgp130 ELISA kit.Methods:The mAb T2 against human gp130 was used as coating antibody;the other mAb T12 recognized different epitope with T2 was labeled by biotin,then a ELISA kit for detecting sgp130 was set up.Results:sgp130 ELISA kit is successfully established and its sensitivity is 10 ng/ml.After the kit is placed in 4℃ for 3 months,the kit's CV is less than ?7.6% and the retrievable rate is 95%～111%.These indicate that it has highly sensitivity,stability and accuracy.The normal serum concentration of sgp130 in healthy donors is 536.92～287.88(ng/ml),but there is higher in patients with hyperthyroidism(937.16?217.5) and chronic nephritis(806.45?138.47).Significant difference is found comparing with normal control(P

ve To improve the method of determination of aluminium in water. Methods The method of aluminium chrome azurol S-cetylpyridinium bromide spectrophotometry was used. Results The improved determi-nation of aluminium revealed perfect linear relationship in determining the standard aluminium solution series at the range of 0. 0-6.0?g/25 ml aluminium. The regression equation was calculated as y = 1. 031x + 0. 008(r=0.9994) . The detection limit was 0.02 mg/L aluminium. The coefficient variation was below 4.90% . The recovery rate ranged from 93.3% to 100.0% . Conclusion The improved method was rapid and easy to operate, suitable for determination of Al3+ in a large number of water samples.

Objective:To describe the doctors' satisfaction of the doctor-patient relationship and find out the influencing factors of the patients,gathering evidence to improve the doctor-patient relationship.Methods:This study was a cross-sectional study,in which doctors and nurses in 10 hospitals of Beijing,Shandong and Chongqing were surveyed with structured questionnaires and in-depth interviews.Results:The mean score of the doctors' satisfaction of the doctor-patient relationship was 59.97,which was much lower than the patients'.The patients' socio-demographic characteristics,social economic status(SES) and behavior characteristics influence the interaction of the doctors and the patients.The doctors' satisfaction of the doctor-patient relationship was influenced by the patients' trust.Conclusion:The doctors' perspective is helpful to define the tension and the cause of the doctor-patient relationship.The patients' characteristics have important influence on the doctor-patient relationship.It's necessary to take action on the patients to improve the doctor-patient relationship.
