This paper provided a systematic review of this disease entity in order to promote neurologists, neurosurgeons and radiologists′ experience in the diagnosis and treatment of the disease.

Objective To explore the safety and therapeutic effect of Xuebijing injection for treatment of patients with capillary leak syndrome (CLS).Methods Seventy-seven patients with clinical diagnosis of CLS admitted to Intensive Care Unit (ICU) of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine (TCM) from November 2015 to October 2016 were enrolled, they were divided into a control group (35 cases) and a Xuebijing group (42 cases) according to random number table method. The conventional treatment was given and at the same time the primary disease was actively treated in the control group; while in the Xuebijing group, on the basic treatment of the control group, additionally, Xuebijing injection 100 mL+ 0.9% normal saline (100 mL) was intravenously dripped, twice a day, 5 days constituting one therapeutic course. Before and after treatment for 5 days, the white blood cell count (WBC), neutrophils percentage (N), alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), serum creatinine (SCr), procalcitonin (PCT), pH value, partial pressure of blood oxygen (PaO2), blood lactic acid value (Lac), activated partial thromboplastin time (APTT), prothrombin time (PT), blood platelet count (PLT) in the patients of the two groups were compared; and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was recorded; the length of stay in ICU, mechanical ventilation time, and 28-day survival rate were statistically calculated in two groups.Results After treatment, the levels of WBC, N, PCT, ALT, AST, BUN, SCr, Lac, APACHE Ⅱ score in Xuebijing group were lower than those in the control group [WBC(×109/L): 9.85±0.61 vs. 13.87±2.58, N: 0.75±0.08 vs. 0.90±0.10, PCT (μg/L): 1.13±0.71 vs. 4.99±1.38, ALT (U/L): 79.56±30.85 vs. 84.21±27.32, AST (U/L): 91.98±38.10 vs. 110.28±35.79, BUN (mmol/L): 7.35±0.82 vs. 8.57±1.43, SCr (μmol/L): 111.67±43.96 vs. 132.51±55.10, Lac (mmol/L): 1.88±1.01 vs. 3.31±1.46, APACHE Ⅱ score: 11.34±3.59 vs. 17.65±4.77]; the PaO2, PLT, 28-day survival rate in Xuebijing group were higher than those in the control group [PaO2 (mmHg, 1 mmHg = 0.133 kPa): 75.47±21.10 vs. 54.22±15.23, PLT (×109/L): 211.54±58.25 vs. 153.27±49.69, 28-day survival rate: 85.71% (36/42) vs. 71.43% (25/35), allP < 0.05]; the PT, APTT, ICU hospitalization time and mechanical ventilation time in Xuebijing group were shorter than those in the control group [PT (s): 13.62±2.11 vs. 18.45±4.26, APTT (s): 31.33±4.27 vs. 36.85±5.56, length of stay in ICU (days): 12.4±3.7 vs. 20.5±4.1, mechanical ventilation time (days): 10.5±4.9 vs. 18.7±5.5, allP < 0.05].Conclusion The application of Xuebijing injection for treatment of patients with CLS can relieve their disease situation, reduce inflammatory indicators, improve the blood coagulation function and hypoxemia, shorten the ICU hospitalization time and mechanical ventilation time, elevate the 28-day survival rate, and has no harmful effects on liver and kidney functions.

Objective: To study the content of alkaloids in Huanglianjiedu Decoction and its disassemble prescription. Methods: The contents of four alkaloids such as berberine, jatrorrhizine, coptisine, palmatine in Huanglian jiedu Decoction and its disassemble prescription were determined by HPLC. Results: The content of four alkaloids extracted by tranditional decoction had a tendency to low. On the coutrary, when Rhizoma Coptis and Cortex Phellodendri were decocted together the quantity of alkaloids was additive, and when two herbs above decocted with Radix Scutella and Fructus Gardeniae the quantity of alkaloids decreased obviously. Conclusion:This study can provide a basis for establishing rational quanlitative standard for Huanglianjiedu Decoction.

Influences of environment on medical equipment lie in many fields and exist independent of human consciousness.In order to lengthen the service life of medical equipment and produce the best possible results,human beings use scientific methods to utilize and change the natural situation.Bad influence from natural conditions to medical equipment is expatiated from such aspects as influence from thunder,rain,snow,electricity,warmth,humidity,mist,magnetism,etc.The management and the protection of the medical equipment under the natural situations are discussed.

BACKGROUND: Collagen sponge is considered the most useful biomaterial owing to its excellent function and properties, easy processing, sterilization, and preservation and has been widely used in scientific research and clinical application. OBJECTIVE: To describe the properties of collagen sponge and to review the research progress of collagen sponge in clinical application in recent years. METHODS: A computer-based retrieval was performed by the first author to search for manuscripts published from January 2000 to August 2010 in Pubmeds and Elsevier databases and for manuscripts published from January 1993 to August 2010 in CNKI database using key words "collagen, collagen sponge, clinical application" in title and abstract items in English and Chinese language, respectively. RESULTS AND CONCLUSION: Collagen sponge, as a new biological material, has been widely applied in tissue engineering research in terms of hemostasis, wound healing, anti-infection, cartilage repair, and nerve repair. But at present, nearly all collagen is from animals and immunogenicity cannot be thoroughly eliminated. Researchers outside of China have synthesized recombinant human collagen using bioreactor and transgenic technology, but its efficacy and safety in clinical application needs further investigation and research.

Fibroblast growth factor(FGF)-21 is a novel insulin-independent glucose regulator,and can be a potential therapeutics for treatment of type Ⅱ diabetes.Although FGF-21 was discovered recently,the insight into its biology and therapeutic utility is rapidly evolving.A number of key metabolically-linked molecules and pathways have been suggested to be involved in the mechanism of action of FGF-21,which enables us to renew the understanding of the FGF-21.The aim of this review is to report the update research outcomes.

Objective: A HPCE capillary zone eletrophoretic method for the determination of evodiamine in Fructus Evodia was established. Similarly, areliable HPCE-FPS (fingerprint spectrum) was applied to compare quality of Fructus Evodia to 14 samples of 3 species from different areas. Methods: The evodiamine was detected on 254nm and proteins was on 196nm、254nm by HPCE. The electrophoretic parameters were optimized by studying the efffect of the buffer composition. Results: Calibration graph was constructed in the range 1.944 ?g?mL -1～7.766 ?g?mL -1 for evodiamine (r=0.9974). The regression equation was y= 188.7x-32.1. The average recovery was 101.3 (n=3). In this paper, the proteins of Frutus Evodia HPCE-FPS was established at 196nm and 254nm. Conclusion: Content of evodiamine from Fructus Evodia was determined by HPCE-CZE and HPCE-FPS and distinguished three species from different growing areas related to intrinsic quality of them. The research provides new technique for evaluating quality of traditional Chinese medicine.
