Objective To study into the influence of Ze Xie and Dan Shan root on the immunity regulation and the expression of radical in mice with chronic pelvic infection. Methods The model of mice with chronic pelvic infection was established by putting phenol into the endometrium of the mice. The density change of serum IL -2, TNF, SOD and MDA of the mice was measure by the method of radiation immunity and the method of biochemistry. Results The expression of serum IL - 2 and SOD in Ze Xie and Dan Shan root group was obviously higher than that in the model group( P

To explore the feasibility of rapid proto-typing ( RP) technology in the treatment of Standford type A aortic dissection. 5 patients with Standford type A aortic dissection received computed tomography angiography (CTA) of their aortas. The CTA images were then processed by 3D reconstruction with MIMICS16. 0 in order to create aortic dissection models through RP technology based on real patient aorta size with a ratio of 1 ∶ 1 . Accord-ing to these models, the surgeons were able to fully understand the aortic diseases of patients, thus establish indi-vidualized treatment strategies for each patient. Besides, the surgeons simulated operations on the models, which helped them achieve better results in real surgery. These patients experienced no post-operative complications and were discharged from hospital with recovery. In conclusion, RP technology can provide adequate preoperotive prep-arations for patients with Standford type A aortic dissection, improve operation efficiency and accuracy in aortic dis-section and guide precise proximal anchoring of stents during intracavitary therapy.

A simple and green method for the determination of trace bisphenol A( BPA) was established by coupling supported ionic liquid solid phase extraction to β-cyclodextrin modified ionic liquid carbon paste electrode-based electrochemical detection ( SILs-SPE-ED) . The synthesized imidazolium ionic liquid modified styrene type macroporous resin was used as adsorbent for SPE of BPA. The critical parameters that affect the extraction efficiency were optimized, including 0. 4 g of packing material quantity, 200 mL of sample solution at pH 7. 0, 5 mL of methanol as an eluent solvent, and 4. 5 mL/min of the SPE flow rate. Dynamic adsorption test showed that the maximum adsorption capacity of BPA on the SILs-SPE cartridge was 10. 1 mg/g, and the enrichment factor was 40 . The calibration curve showed a good linearity between the anodic current and the BPA concentration in the range of 1. 0×10-8-1. 0×10-6 mol/L (i. e. 2. 3-228μg/L). The detection limit was 4. 16×10-9 mol/L (equal to 0. 95 μg/L). The SILs-SPE-ED method was applied to the analysis of water and plastic samples and the results agreed well with HPLC method.

Objective: To investigate the influencing factors for delay in healthcare-seeking, definitive diagnosis and identification in patients with pulmonary tuberculosis (PTB) in Minhang District, Shanghai Municipality, so as to provide the basis for effectively reducing delay in PTB patients. Methods: Data of PTB patients in Minhang District from 2017 to 2022 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. The prevalence rates of delay in healthcare-seeking, definitive diagnosis and identification were analyzed, and factors affecting delay in healthcare-seeking, definitive diagnosis and identification were identified using multivariable logistic regression models. Results: A total of 4 214 PTB patients were reported in Minhang District from 2017 to 2022, including 2 802 males and 1 412 females, with a male-to-female ratio of 1.98∶1. The majority of patients were aged 25 to <45 years (1 664 cases, 39.49%). The prevalence rates of delay in healthcare-seeking, definitive diagnosis and identification were 36.81%, 30.21% and 38.09%, respectively. Delay in healthcare-seeking was associated with the year (2018, OR=0.708; 2019, OR=0.549; 2020, OR=0.670; 2021, OR=0.682), gender (female, OR=1.199), occupation (worker, OR=1.379; housekeeping service/housework/unemployed, OR=1.481), case identification route (symptom-based consultation, OR=11.159), and level of the first-diagnosed hospital (city-level, OR=1.528). Delay in definitive diagnosis was associated with age (45 to <65 years, OR=1.476), occupation (commercial service, OR=0.687; housekeeping service/housework/unemployed, OR=0.672), household registration (non-local, OR=0.820), case identification route (symptom-based consultation, OR=0.616), pathogen test result (negative/not tested, OR=1.903), and the level of the first-diagnosed hospital (city-level, OR=0.311). Delay in identification was associated with the year (2018, OR=0.785; 2019, OR=0.647; 2020, OR=0.790; 2021, OR=0.710), occupation (commercial service, OR=0.687), household registration (non-local, OR=0.848) and level of the first-diagnosed hospital (city-level, OR=0.560) Conclusions Year, gender, occupation, case identification route and level of the first-diagnosed hospital are influencing factors for delay in healthcare-seeking in PTB patients. Age, occupation, household registration, case identification route, pathogen test result and level of the first-diagnosed hospital are influencing factors for delay in definitive diagnosis. Year, occupation, household registration and level of the first-diagnosed hospital are influencing factors for delay in identification.

A HPLC method for determination of limonin, evodiamine and rutaecarpine in Evodia rutaecarpa was optimized. The mobile phase was [acetonitrile-tetrahydrofuran (25: 15)] -0.02% H3 PO4 (35:65). The detection wavelength was 220 nm and the flow rate was 1.0 mL x min(-1). Limonin, evodiamine and rutaecarpine were all well separated from other substances and their UV spectrums were essentially the same to the standards . The liner ranges of limonin, evodiamine and rutaecarpine were 0.196 8-3.936, 0.153 6-3.072, 0.097 4-1.948 microg. The average recoveries were 97.8%, 100.7% and 98.4%. RSD were 1.7%, 1.3% and 1.1% (n = 6). The method of this article is accurate, reproducible and can be used to enhance the quality control of E. rutaecarpa.

Objective:To investigate the influence of moxibustion products on mitochondrial transmembrane potential (MTP) and mRNA expression of Bax/Bcl-2 in alveolar typeⅡ epithelial A549 cells, and to further explore influence of moxibustion products on the oxidative damage of A549 cells. Methods:Smoke and particles generated by moxibustion were collected using the filter box for gas sampling. The moxa smoke extract (MSE) was diluted sequentially to the final concentrations of 0.05 mg/mL, 0.1 mg/mL, 0.2 mg/mL, 0.3 mg/mL and 0.4 mg/mL using the cell culture medium, and A549 cells were then intervened by the above MSE solution. Cell MTP was detected by JC-1 staining. Fluorescence quantitative polymerase chain reaction (PCR) was used to detect Bax/Bcl-2 mRNA expression of A549 cells. Results: Compared with cells in the normal control group, MTP was significantly decreased in cells of 0.3 mg/mL and 0.4 mg/mL MSE intervention groups (P<0.01); while MTP showed no significant changes in cells of 0.05 mg/mL, 0.1 mg/mL and 0.2 mg/mL MSE intervention groups (P>0.05); compared with cells in 0.05 mg/mL MSE intervention group, MTP was decreased significantly in cells of 0.1 mg/mL, 0.2 mg/mL, 0.3 mg/mL and 0.4 mg/mL MSE intervention groups (P<0.05 ); compared with cells in 0.1 mg/mL MSE intervention group, MTP was decreased significantly in cells of 0.4 mg/mL MSE intervention group (P<0.01). Bax mRNA expression of cells in each concentration of MSE intervention group all showed no significant difference compared to that in the normal control group; Bcl-2 mRNA expression of cells was reduced with the increase of MSE intervention concentration. Wherein, Bcl-2 mRNA expressions of cells in 0.4 mg/mL and 0.3 mg/mL MSE intervention groups were significantly reduced compared with that of cells in the normal control group (P<0.05); Bcl-2 mRNA expression of cells in 0.4 mg/mL MSE intervention group was significantly reduced compared to that in 0.05 mg/mL MSE intervention group (P<0.05). Conclusion:Certain higher concentration of moxa smoke could reduce MTP and mRNA expression of the anti-apoptosis gene Bcl-2 in alveolar typeⅡ epithelial A549 cells. Oxidative damage may be the important mechanism of apoptosis caused by the high concentration of moxa smoke solution, and further studies are necessary on the specific mechanisms.
