In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

Objective To discuss human papilloma virus(HPV)prevalence and HPV genotypes distribution and the infection factors,to provide scientific guidance for the prevention and treatment of cervical cancer.Methods From March to November in 2009,605 women received cervical HPV testing in the Tumor Hospital of Harbin Medical University,to obtain specimens of cervical cytology,rapid flow-through hybridization technique (namely Hybribio flow-through hybridization)was used to detect HPV genotypes simultaneously.Single-factor and multivariate factors non-conditional Logistic regression analytic method was used to discuss the relationship between HPV infection of females and age,marital condition,level of education,level of income,occupation,initial age for sex,contraception,number of pregnancies,delivery approach and smoking.Results HPV infection rate was 21.49%(130/605),the positive rate of HPV infection in high-risk subtypes was 15.70%(95/605),the most common type was 5.29%(32/605)in the samples.Single factor non-conditional logistic regression model analysis showed that initial age for sex was the risk factor(X2=4.4618,P<0.05),HPV prevalence increased with a lower initial age for.sex reduced.But there was no significant difference in age,marital condition,education,income,occupation,contraception,number of pregnancy,delivery approach and smoking teams(X2=0.0525,1.8510,1.0348,0.2592,1.1176,1.5664,2.8835,1.4597,2.6161,all P>0.05).The analysis of multivariate factors nonconditional Logistic regression showed that the age of initially having sex,marital status and number of pregnancies were the risk factors(X2=21.6637,8.0574,15.7573,all P<0.05).Conclusions The risk factors for HPV infection are mainly about having sex too young,marital status and number of pregnancies,attention should be paid to screening for HPV.

Diabetic ulcer is recognized as a chronic nonhealing wound, often associated with bacterial infection and tissue necrosis, which seriously affect patients' health and quality of life. The traditional treatment methods exist some problems, such as bacterial resistance and secondary trauma, so it is urgent to find new methods to meet the requirements of diabetic ulcer treatment. In this study, we prepared a drug delivery system (DFO@CuS nanoparticles) based on hollow copper sulfide (CuS) nanoparticles loaded with deferoxamine (DFO), which realized the synergistic therapy of promoting angiogenesis and photothermal antibacterial. The morphological structure and particle size distribution of DFO@CuS nanoparticles were characterized by transmission electron microscopy and particle size analyzer, respectively. The antibacterial effect of DFO@CuS nanoparticles was evaluated by the plate coating method. The effects of DFO@CuS nanoparticles on the proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs) were evaluated by CCK-8 (cell counting kit-8) assay, cell scratch assay, and tube formation assay. The results showed that DFO@CuS nanoparticles were hollow and spherical in shape with an average particle size of (200.9 ± 8.6) nm. DFO@CuS nanoparticles could effectively inhibit the growth of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (PA) under near-infrared (NIR) light irradiation. DFO@CuS nanoparticles showed negligible cytotoxicity and effective acceleration of cell migration and tube formation in a certain concentration range. In conclusion, the prepared DFO@CuS nanoparticles exhibit good photothermal antibacterial properties and pro-angiogenic effects, providing a basis for their application in the treatment of diabetic ulcer.

This study was purposed to investigate the effects of interferon (IFN)-γ on expression of adhesion molecules in mesenchymal stromal cells derived from human umbilical cord tissue (UC-MSC). The UC-MSC were isolated from human umbilical cord by tissue culture. The expressions of specific markers on UC-MSC were detected by flow cytometry in the physiological condition. The adipogenic and osteogenic induction of UC-MSC was detected by alizarin and Oil red O staining. UC-MSC were exposed to IFN-γ (100, 1 000, 10 000 U/ml) for 24 h, the expressions of CD54, CD58, CD44, CD49d, CD62p, CD62L, CD102 and CD106 on cell surface were detected using flow cytometry. The results showed that in physiological condition, UC-MSC extremely low expressed CD102, CD106, CD62P, CD62L, while the expression of CD54 was relatively high (41.58 ± 0.83)%. When stimulated by IFN-γ, the expression of CD102, CD106, CD62P, CD62L increased slightly, but still low (< 5%), while CD54 and CD58 upregulated concentration-dependently up to (59.66 ± 1.36)% and (43.96 ± 0.62)% respectively. The expression of CD49d upregulated to (51.33 ± 0.74)% when UC-MSC exposed to IFN-γ 100 U/ml. CD44 increased to (73.22 ± 1.93)% when UC-MSC exposed to IFN-γ 1 000 U/ml. It is concluded that IFN-γ can elevate significantly the expression of CD54, CD49d, CD44 and CD58, but has no significant effect on CD102, CD106, CD62P and CD62L expression on the surface of UC-MSC.
