To explore the new pattern of Chinese medicine solid preparations (CMSP) in vitro dissolution, a method testing the bio-thermal activity in combination with UPLC was used. Microcalorimetry was used to obtain the characteristic metabolic growth power-time curves and a series of biothermodynamic parameters of the inhibition of Staphylococcus aureus by Yinhuang tablet dissolving solutions at the pH 6.8 (phosphate buffer) dissolution medium at different times. From these results, the cumulative dissolution of Yinhuang tablet based on bio-thermal activity was obtained. The dissolution rates of two components of chlorogenic acid and baicalin were determined by UPLC method. Then f2 similar factor method was used to evaluate the relevance of these two methods. The result showed that f2 values all were more than 50, indicating that there is a good correlation between the two methods of measuring the dissolution rate. It is feasible to determine CMSP in vitro dissolution by using bio-thermal activity, and to provide new evaluation methods for controlling the quality of CMSP.

Objective To observe the therapeutically effect of kangnao liquid on Pi3k mRNA and Aktm RNA ex-pressions in rats with focal cerebral ischemia-reperfusion (I/R) injury. Methods 180 male SD rats were randomly divided into 6 groups:sham operated group, model group, three kangnao liquid groups (high-dose, medium-dose and low-dose) and nimodipine group. Rats in kangnao liquid groups were administrated with kangnao liquid of 24 g/(kg · d), 12 g/(kg · d) and 6 g/(kg · d), orally once a day. Rats in nimodipine group were given nimodipine 1 mg/(kg · d). Rats in model group and sham group were treated with the same volume of distilled water for 7 days. The animal model of middle cerebral artery occlusion (MCAO) was established by a monofilament method from right internal carotid artery. The neurological evaluation was per-formed 24 h after reperfusion. The in situ hybridization was used to investigate the expression levels of Pi3k mRNA and Akt mRNA in rats on 12 h, 24 h, 48 h, 72 h and 168 h after ischemia for 2 h. Results Compared with model group, neurological functions were improved significantly in kangnao liquid groups. The expression levels of Pi3k mRNA and Akt mRNA were al-so significantly higher in kangnao liquid groups than those of model group. The expression levels of Pi3k mRNA and Akt mRNA were significantly higher in nimodipine group than those of model group, but which were lower compared with those of high-dose and medium-dose kangnao liquid groups. Conclusion Kangnao liquid can protect nerve cells by enhancing the expressions of Pi3k mRNA and Akt mRNA in rats with cerebral ischemia-reprefusion injury.

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

Objective To investigate the early diagnostic and prognostic value of plasma D-dimer level in acute aortic dissection.Method Data of totally 500 acute chest pain patients were studied,in which 250 cases were in group of acute aortic dissection (group AAD) confirmed by aortic computerized tomographic angiography (CTA) or cardiac ultrasonography,and the rest 250 cases were in non AAD group (group control).The D-dimer test was performed in all patients within 72 hours after onset of chest pain,and comparison of plasma D-dimer concentration was carried out between two groups.The D-dimer diagnostic value in AAD was analyzed by plotting the receiver operating characteristic (ROC) curve.According to AAD patients with aortic CTA findings,the whole aortic artery was divided into four segments by the major vascular branches,and the false lumen area was measured by degree score,the relationship between the score and D-dimer level were analyzed.To study the prognostic value of D-dimer in AAD,the comparison of D-dimer level was carried out between survival group and death group,and the AAD patients were further stratified by the surgery and Stanford type.Results The plasma D-dimer concentrations in AAD group were significantly higher than those in controls (P ＜0.01).The sensitivity,specificity,positive predictive value and negative predictive value of D-dimer (＞ 1.14 mg/L) in the diagnosis of AAD were 81.2％,79.39％,74.63％ and 72.4％ respectively,and the area under the ROC curve was 0.083.The elevated level of D-dimer was positively correlated with the extent of AAD false lumen (Spearman-Rho =0.418,P ＜ 0.01).D-dimer levels in the death group were higher than those in the survival group.Conclusions D-dimer may be a valuable biomarker in early diagnosis of AAD.The elevated level of D-dimer was useful to evaluate the extent of the dissection and prognosis of AAD.

Aiming at molybdate and boron deficient acid purple soil from main peanut cultivated areas in Sichuan,and Mo and B requirement of peanut growth,the feasibility of Co-inoculum of peanut Bradyrhizobium and molybdate and boron was studied.The tolerance to molybdate and boron of the tested strains Spr2-9,Spr4-5 was inspected.The result indicated that the two tested strains could tolerate higher concentration of molybdate than that of boron.The compound inoculum of Bradyrhizobial strain and trace element Mo was developed.The optimum concentration of Mo was 0.4%.

"Heyaofenji", "Hehe", " Heji" in ancient Chinese medicine, herbal medicine literature and law were collected, and then things were sorted out according to traditional Chinese medicine dispensing theory, skills and legal norms. Firstly, "Tang Ye Jing Fa" is the earliest book which marks the rudiment of traditional Chinese medicine dispensing. Secondly, traditional Chinese medicine dispensing theory formed in "Shen Nong's herbal classic". Thirdly, Zhang Zhongjing's "Treatise on Febrile Diseases" marked the formation of Chinese medicine dispensing skills. Lastly, Provisions in Tang Dynasty law marks the development of traditional Chinese medicine dispensing.
