According to two theories,which are "traditional Chinese medicine researching is in the face of a complex opening gigantic system" and "Chinese materia medica compound(CMMC) is the natural combinatorial chemical libraries",the study on active fractions of CMMC has been facing to a complex system with a large number of data that is non-linear,multi-variable,and varieties related to each other.The thinking and method of "combinatorial screening" has been put forward based on these two theories,that is the principle "using the diverse structures of molecules to simulate the diverse organism" used in combinatorial chemistry and the data mining technique was taken into the study on complex system of CMMC.In order to create combinatorial libraries,the two methods were used to obtain the fractions of CMMC.Re-combination group of the CMMC was used,and various industrial separation techniques, such as resin,membrane,were used to replace the diversity of chemosynthesis routes to create "Building Block".Through data mining and knowledge discovery, the intrinsic correlation of CMMC "multi-components and multi-targets" between the chemical composition and the mechanism was carried out.The new technologies which aim at high-throughput screening of CMMC were explored,in order to provide the evidence for setting up an idea with "optimal separation" and optimization design about application system of refining technology.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.

METHODUV was applied to determine the concentration of total alkaloids and total flavones; Simultaneous determination of berberine, jatrorrhizine, palmatine, baicalin and geniposide were carried out by HPLC; The solid holdup and precipitation rate were calculated by the formula. The relativity among these parameters was analyzed by the SPSS software program.

RESULTThe contains of berberine, jatrorrhizine, palmatine in total alkaloids showed a good correlation with total alkaloids. The correlation between baicalin and total flavones was lower than that between geniposide and total flavones. Compared to precipitation rate, solided hold up shows a larger relevance with index component

CONCLUSIONWith the change of time, the total alkaloids represented by berberine alkaloids and baicalin at a certain concentration can be regarded as the equilibrium point, or one generated by the critical point of precipitation, the reaction can generate "sediments"; because "precipitation objects" generated, reducing the concentration of the above-mentioned components, destroy the" balance". The relevant components of herbal medicine increased dissolution rate, at the same time might partly dissolved sediment, reaching a new equilibrium state.

Objective To examine the effect of patient-centered care services on compliance to treatment among patients with multidrug-resistant (MDR) or rifampicin-resistant (RR) pulmonary tuberculosis (PTB), so as to provide the scientific evidence for promoting the widespread application of the appropriate nursing process of MDR/RR-PTB patients in the hospital. Methods The MDR/RR-PTB patients that were definitely diagnosed at the Sixth People’s Hospital of Nantong City during the period from January 2017 to October 2020 were enrolled. The patients with confirmed diagnosis of MDR/RR-PTB during the period January 2017 to December 2018 served as controls, who were given routine care in the hospital, and those with confirmed diagnosis of MDR/RR-PTB during the period January 2019 to October 2020 served as the care group, who were given patient-centered personalized care services, including one-to-one consultations, periodic group activities, informatization case management, and personal reminder for return visits. The proportion of inclusion into treatment, loss to follow-up, return visits and sputum examinations were compared between the care and control groups. Results A total of 104 MDR/RR-PTB patients were included, including 54 cases in the control group and 50 cases in the care group. There was no significant difference in gender and age distribution between the two groups (χ² = 3.013, 1.336, P > 0.05). The proportion of inclusion into treatment was higher in the care group (100.00%, 50/50) than in the control group (87.04%, 47/54) (P = 0.013), and the proportion of loss to follow-up was lower in the care group (0, 0/43) than in the control group (19.05%, 8/42) (P = 0.002). In addition, the overall proportion of return visits was higher in the care group (93.09%, 377/405) than in the control group (83.56%, 371/444) (χ² = 18.345, P < 0.001), and the proportion of sputum examinations was higher in the care group was (83.70%, 339/405) than in the control group (79.28%, 352/444) (χ² = 2.737, P = 0.098). Conclusion Patient-centered care services facilitate the improvements in the proportion of inclusion into treatment and compliance to treatment and reduction in the proportion of loss to follow-up among MDR/RR-PTB patients, which deserves widespread applications.

Objective:To explore the effect of clinical conventional fractionated dose radiation on the expression levels of immunogenic cell death (ICD) related proteins in patients with nasopharyngeal carcinoma (NPC).Methods:A total of 38 newly-treated NPC patients admitted to the Affiliated Cancer Hospital of Guizhou Medical University from November 2020 to December 2021 were enrolled, all of whom received induction chemotherapy and concurrent chemoradiotherapy, and another 20 healthy volunteers were selected as controls for a prospective study. The contents of ICD related proteins, namely calreticulin (CRT), high mobility group box 1 protein (HMGB-1) and heat shock protein 70 (HSP70) and the proportion of dendritic cell (DC) in the peripheral blood of patients were detected before treatment, after induction chemotherapy and after concurrent chemoradiotherapy, respectively. The correlation between the above indicators, general clinical data and short-term efficacy was analyzed by statistical methods such as t-test and analysis of variance (ANOVA). Results:The levels of HSP70 and HMGB-1 in peripheral blood of NPC patients before treatment were higher than those of healthy controls (both P<0.05). After concurrent chemoradiotherapy, the content of CRT was significantly higher than that before treatment ( P<0.05), whereas the difference before and after induction chemotherapy and the difference before and after concurrent chemoradiotherapy were not significantly correlated with the short-term efficacy of NPC patients. HSP70 level was significantly decreased after concurrent chemoradiotherapy ( P<0.001). There were no significant differences in the content of HMGB-1 after induction chemotherapy and concurrent chemoradiotherapy (both P>0.05). Conclusion:NPC patients receiving TPF regimen (docetaxel+cisplatin+fluorouracil) for induction chemotherapy and sequential cisplatin concurrent chemotherapy may induce ICD in NPC cells, and CRT has potential value in reflecting the clinical efficacy of NPC.
