Objective To investigate the changes of cesarean section rate and indications in different level hospitals of different areas in China during 2000 to 2009. Methods Literatures published in Chinese journals on variation of cesarean section rate and indications from 2000 to 2009 were analyzed. Cochran-Armitage test was used to analyze the trend. The differences of cesarean section rate between different areas or different level hospitals were analyzed by chi-square test.Results Forty-nine papers were enrolled in this study.Cesarean section rate had risen from 2000 (32.1％,10 353/32 258) to 2009 (52.5％,3674/6992)(Z=-20.8267,P＜0.01).During 2000 to 2008,the average cesarean section rate of level one grade A hospital was 45.7％ (3754/8214),which was higher than 34.5％(25 015/72 507) in level three grade A hospital and 32.3％(28 140/87 121) in level two grade B hospital (P＜0.05,respectively).Except for level three grade A hospital,cesarean section rate had risen in the other two level hospitals during 2003 to 2008. The average cesarean section rate was 58.6％ (4982/8502) in northeast area during 2000 to 2007,which was higher than that of other areas (P＜0.01); and the average cesarean section rate was 27.5％ (12 264/44 595) in central China and 33.0％ (23 239/70 421) in southern China,which were lower than that of other areas (P＜ 0.01 ). Social factor,instead of dystocia,became the most important indication for cesarean section,and its proportion kept rising annually,from 11.3％ (1170/10 353) in 2000 to 27.1％(2094/7726) in 2008 and remained above 20.0％(5159/24 691) since 2004.The proportion of scar uterus rose from 6.7％(694/10 353) in 2000 to 12.5％ (459/3674) in 2009. Conclusions Cesarean section rate rises fast and its major indications had changed in China. It is suggested that special method should be taken to control the current situation.

The experimental research literatures on traditional Chinese medicines in the treatment of systemic lupus erythematosus ( SLE) in recent years were systematically reviewed , which focused on single herb and its effective components , and compound herbs therapy.It is confirmed that Chinese medicines show exact therapeutic activity on SLE with multi-targeting effects.

This paper summarized training status of the Master of Nursing Specialist (MNS) at home and abroad,described and analyzed the cultivation program at home and abroad,and discussed the problems about cultivation objective, enrollment, course system, specialty orientation, clinical training model, teaching method, connotation of practical ability, teachers strength, evaluation and assessment in cultivation of MNS in China. Then MNS training program is proposedso as to provide references for the future cultivation program of MNS in China.

In the face of escalating problems with pathogen control, the development of proper formulations of existing antibiotics is as important as the development of novel antibiotics. Daptomycin is a lipopeptide antibiotic with potent activity against Gram-positive bacteria. Currently, only injectable solution of daptomycin has been approved for clinical use. In the present study, the formulation of PEGylated liposomal daptomycin (PLD) was prepared and optimized, and its efficacy against methicillin-resistant Staphylococcus aureus (MRSA252) strains was investigated. The obtained PLD had a mean vesicle diameter of (111.5 +/- 15.4) nm and a mean percent drug loading of (5.81 +/- 0.19) % with high storage stability. Potent activity of PLD against MRSA was demonstrated in vitro with a more sustained effect than that of conventional liposomal daptomycin and daptomycin solution. In addition, intravenous administration of a single dose (equal to human use) of PLD significantly increased the survival of mice in a MRSA252 systemic infection model compared with other formulations. Drug distribution in the lung was significantly enhanced following administration of PLD, and no measurable tissue lesions or pathological changes were detected during PLD treatment. Taken together, PEGylated liposomes loaded with daptomycin may represent a promising approach to reduce MRSA252 infections, especially those involving bloodstream dissemination, such as hematogenous pulmonary infection.

The HPLC fingerprint determination method of Jinzhen oral solution was established to provide a new method for quality control of Jinzhen oral solution. RP-HPLC was used for phenomenex Luna C18 (4.6 mm x 250 mm, 5 μm) chromatographic column, with 0.1% H3 PO4 water solution and acetonitrile as the mobile phase for gradient elution. The detection wavelength was 280 nm. HPLC fingerprint of Jinzhen oral solution was established to identify 17 common peaks in Jinzhen oral solution. The similarity of fingerprints of 10 batches of finished products was more than 0. 90. The established HPLC fingerprint has a better precision, reproducibility and stability, and can be applied in quality control of Jinzhen oral solution.

In this study, we developed a novel liposome-silica hybrid nano-carrier for tumor combination therapy via oral route, using paclitaxel and cyclosporine as a model drug pair. Optimization of the preparation of the drug-loading formulation and characterization of its physicochemical parameters and drug release profile were performed in vitro. Then in vivo pharmacodynamics and pharmacokinetics studies were performed. The results showed that the obtained formulation has a small particle size (mean diameter of 100.2 +/- 15.2 nm), a homogeneous distribution [the polydispersity index was (0.251 +/- 0.018)] and high encapsulation efficiency (90.15 +/- 2.47) % and (80.64 +/- 3.52) % for paclitaxel and cyclosporine respectively with a mild and easy preparation process. A sequential drug release trend of cyclosporine prior to palictaxel was observed. The liposome-silica hybrid nano-carrier showed good biocompatibility in vivo and co-delivery of cyclosporine and paclitaxel significantly enhanced the oral absorption of paclitaxel with improved anti-tumor efficacy, suggesting a promising approach for multi-drug therapy against tumor and other serious diseases via oral route.

OBJECTIVE: To establish bacterial endotoxin test for adenosine disodium triphosphate (ATP) raw material by TAL method. METHODS: The sensitivity of TAL and the limit of endotoxin were reviewed and confirmed. Preliminary interference test was used to determine the dilution ratio of samples and interference test was applied to determine maximum non-interference concentration. Bacterial endotoxin test was performed on 11 batches of samples according to the method stated in Chinese Pharmacopoeia (2005 edition). RESULTS: The sensitivity of TAL was up to the standard and the limit of endotoxin in samples were 2.0 EU?mg-1. The maximum non-interference concentration was 0.125 mg?mL-1. Results of bacterial endotoxins test of 11 batches of samples were all in line with the standard. CONCLUSIONS: It is feasible to detect the bacterial endotoxin of ATP raw material by TAL methods, which can replace pyrogen test.

Sjögren's syndrome is a chronic autoimmune disease with unclear etiology. From the point of etiology, Chinese medicine (CM) theory holds that pathological products like dry toxin, blood stasis are produced in the pathological process. They are both pathologic results and pathogenic factors for its further development. So pathological products are also named as second pathogenic factors. In this article, the concept of second pathogenic factors was sorted and defined. Main second pathogenic factors of Sjögren's syndrome were pinpointed, and their modern medical bases were analyzed. Authors came to a conclusion that clearing away second pathogenic factors is a key point in treating Sjögren's syndrome.
