Understanding the research methods for drug protein targets is crucial for the development of new drugs, clinical applications of drugs, drug mechanisms, and the pathogenesis of diseases. Cellular thermal shift assay (CETSA), a target research method without modification, has been widely used since its development. Now, there are various CETSA-based technology combinations, such as mass spectrometry-based cellular thermal shift assay (MS-CETSA), isothermal dose response-cellular thermal shift assay (ITDR-CETSA), amplified luminescent proximity homogeneous assay-cellular thermal shift assay (Alpha-CETSA), etc., which combine their respective advantages and further expand the application scope of CETSA. These technologies are suitable for the entire drug development chain, from drug screening to monitoring the target binding and off-target toxicity of drugs in patients. Based on the author's research experience, this paper reviews the principles of CETSA and related binding technologies, their application in target discovery, and the progress of data processing and analysis in recent years, aiming to provide reference and reference for the further application of CETSA.

"Paired medicine" belongs to the TCM compatibility, and is often relatively fixed applied in some special cases, with advantages of positive efficacy and simplified medication. The efficacy of paired medicine is not derived from the use of single medicine. It's new function can be realized through the compatibility between single medicine. Professor WEI Zi-xiao is expert in using paired medicine. Most of his commonly used paired medicine comes from some famous TCM prescriptions. Professor WEI Zi-xiao brings forth new ideas on the basis of his own experience and the outcome of modern research, with obvious clinical efficacy.

To develop an analytic method for qualitative and quantitative analysis of dodecatetraenamides A, B in 42 samples of two official species of Asari Radix et Rhizoma( ARR) (37 samples of Asarum heterotropoides var. mandshuricum with different collection time and 5 samples of Asarum sieboldiivar. seoulense). The HPLC-IT-TOF-MS/MS methods for the qualitative and UPLC-PDA methods for the quantitative analysis were established. Dodecatetraenamides A, B were identified by comparing the retention time, UV absorption spectrum and quasi-molecular ion peak [ M + H]+ with the reference compound using HPLC-IT-TOF-MS/MS. The content of dodecatetraenamides A and B in ARR were determined by UPLC-PDA. The separation was successfully carried out on a ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 µm) column eluted with mobile phases of water (A) and acetonitrile (B) in gradient program (0-3 min, 35% B; 3-5 min, 35%-36% B; 5-6 min, 36%-43% B; 6 min-11 min 43% B; 11-12 min, 43%-100% B). The column temperature was 45 °C, and the detection wavelength was set at 254 nm. The flow rate was 0.6 mL · min(-1). On one level mass spectrometry scanning, the results showed that the quasi-molecular ion [M + H] + of both dodecatetraenamides A and B were m/z 248.20. The quantitative method with UPLC-PDA has made the baseline separation of the constituents, which were reported as mixtures in the most literatures. The average recovery of dodecatetraenamides A and B were 97.90% and 99.86%, the relative standard deviation were 0.4% and 1.1%, respectively. The contents of dodecatetraenamides A, B in all ARR samples was in the range of 0.11-3.89 and 0.24-6.65 mg · g(-1). Their contents reduced with the extension of storage time. Compared with the samples of 2013, the average content of the two constituents in the samples collected in year 2002-2003 reduced 34% and 36%, respectively (P < 0.05). Compared the A. sieboldii var. seoulense and A. heterotropoides var. mandshuricum with the same collective time and production area, the average contents of the two constituents in latter were up to (1.59 ± 0.75) mg · g(-1) and (2.90 ± 1.17) mg · g(-1), respectively, significantly higher than that in A. sieboldii var. seoulense (dodecatetraenamide A were (0.78 ± 0.52) mg · g(-1), dodecatetraenamide B were (1.69 ± 0.83) mg · g(-1)) (P < 0.05). The content of the dodecatetraenamide A in overground part was in the range of 0.11-0.33 mg · g(-1), dodecatetraenamide B was 0. 24-0.60 mg · g(-1), which were much lower than that of the underground part of ARR (dodecatetraenamide A was in the range of 0.73-3.89 mg · g(-1), dodecatetraenamide B was 2.11-6.24 mg · g(-1)). The method was certified to be simple, accurate and reliable and could be used for qualitative and quantitative analysis of dodecatetraenamide A and B in different species of ARR, also can be used for the comprehensive quality control of traditional Chinese medicine, Asari Radix et Rhizoma.

OBJECTIVETo explore the relationship between Chinese medicine syndrome patterns (CMSP) and their associated factors in patients with type 2 diabetic nephropathy stage III (DN2-3).

METHODSRetrospective analysis was conducted on 209 patients with type 2 diabetes mellitus (T2DM). The patients were allocated into two groups, the DN2-3 group and the control group. Some related clinical materials and laboratory indexes, including age, course of disease, body mass index (BMI), glycosylated hemoglobin A1c (HbA1c), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood levels of total cholesterol (TC), triglyceride (TG), high and low density lipoprotein (HDL and LDL), serum creatinine (Scr) and microalbuminuria (MALB) as well as their CMSP (both the essential syndrome and the superficial syndrome) in the DN2-3 group were collected and compared.

RESULTSSignificant differences were found between the DN2-3 group and the control group in aspects of course of disease (months, 107.74 +/- 96.19 vs. 82.03 +/- 79.10), BMI (kg/m2, 26.25 +/- 4.02 vs. 24.95 +/- 3.56) and Scr level (mmoL/L, 71.93 +/- 24.24 vs. 65.91 +/- 13.70, P < 0.05). The qi-yin deficiency SP (38 cases, 36.19%), and the blood stasis (51 cases, 48.58%) presented as the dominant essential and superficial CM-SP respectively in DN2-3 patients, holding the highest proportion. Analysis on the relationship of associated indices among patients with different CMSP showed statistical differences presented in level of MALB, i.e. which in pi-shen qi-deficiency SP (128.77 +/- 103.59 mg/24 h) was higher than in yin-deficiency dryness-fire SP and qi-yin deficiency SP (88.43 +/- 68.93 mg/24h and 82.60 +/- 55.22 mg/24 h, P < 0.05); it also presented in HbA1c (%) and TG levels(mmol/L), those in stasis SP were 10.73 +/- 2.71 and 2.29 +/- 1.58 ), in dampness SP were 8.80 +/- 2.19% and 4.37 +/- 5.92, and in stasis-phlegm SP were 8.83 +/- 2.09 and 2.40 +/- 2.18 (all P < 0.05).

CONCLUSIONSThe risk factors for occurrence of DN2-3 may be the course of disease, BMI and Scr. Qi-yin deficiency with blood-stasis is the most commonly encountered syndrome in patients with DN2-3. Relations of MALB with Pi-Shen qi-deficiency pattern; HbA1c with blood-stasis pattern, and TG with dampness syndrome are distinctly exhibited in them.

Methods According to "The Executing Plan for the Work of Surveying Brucellosis Disease in Shaanxi Province", 35 villages(towns) of designated monitoring locations and 24 villages (towns) of randomized monitoring locations in five countries of Weinan were chosen to survey brucellosis disease. The five countries were Chengcheng, Dali, Heyang, Tongguan and Hancheng. High risk populations with a history of contacting livestock and livestock products aged between 7 and 60 underwent clinical and serology examination[rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT)]. All manipulation methods and judging standards were in accord with the "Diagnostic Standard for Brucellosis" (WS 269-2007). Results In the designated monitoring location, a total of 8664 people at high risk were investigated, among whom 1407 people were tested by RBPT test and 27 people were positive,the positive rate was 1.92%(27/1407); 27 people were tested by SAT test and 27 people were positive, the positive rate was 100% (27/27); 25 people were diagnosed and the diagnosis rate was 92.59%(25/27). In the randomized monitoring location, a total of 3464 people at high risk were investigated, among whom 411 people were tested by RBPT test and 3 people were positive, the positive rate was 0.73%(3/411 ), 3 people were tested by SAT test which were all positive and made a definite diagnosis. Twenty-eight new cases were made a definite diagnosis and its incidence was 2.06 in a hundred thousand(28/1 361 618). Conclusions The infection of human brucellosis in Weinan city stays at higher level. The governments should increase input for the monitoring,investigating and disinfecting to prevent the disease from increasing and outspreading.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.

METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).

RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).

CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

OBJECTIVETo explore the mechanism of immunomodulatory activity of triptolide on primary immune thrombocytopenia (ITP)patients-derived plasmacytoid dendritic cells (pDCs).

METHODSpDCs in peripheral blood of ITP patients before therapy (group 1), ITP patients in complete response (ITP-CR, group 2) and healthy donors (group 3) were sorted by flow cytometry, then incubated with triptolide at 0, 5, 10 or 30 µg/L. After 24 hours, we collected the supernatants and then detected the concentrations of IFN-α, IL-6 and TNF-α using ELISA. After 5 days, the cultured cells were collected and CD11c, CD80 and CD86 expressions of myeloid dendritic cells (mDCs) were analyzed by flow cytometry, the morphology of mDC was observed by light microscope and electron microscope.

RESULTSAfter incubation with triptolide at 10 µg/L, the levels of IFN-α, IL-6 and TNF-α in group 1 \[(451.32 ± 85.77) ng/L, (105.68 ± 23.85) ng/L and (135.78 ± 30.62) ng/L\] and group 2 \[(391.71 ± 72.49) ng/L, (84.73 ± 17.77) ng/L and (108.16 ± 23.21) ng/L\] were significantly higher than those in group 3 \[(335.51 ± 67.54) ng/L, (73.62 ± 21.82) ng/L and (95.58 ± 32.85) ng/L\] (all P < 0.05); the levels of IFN-α, IL-6 and TNF-α in group 1 were significantly higher than those in group 2 (all P < 0.05) in a dose-dependent manner (P < 0.05). CD11c, CD80 and CD86 expressions of mDC in group1 and group 2 were significantly higher than those in group 3 (all P < 0.05); CD11c, CD80 and CD86 expressions of mDC in group 1 were significantly higher than those in group 2 (all P < 0.05) also in a dose-dependent manner (all P < 0.05). Triptolide could inhibit pDCs from differentiation into mDCs, the latter displayed more immature morphology than untreated-pDCs.

CONCLUSIONTriptolide could decrease the immune function of pDCs from ITP, inhibit pDCs from differentiation and maturation.
