Objective To observe the bacteriostasis of herba houttuyniae liquid in bladder irrigation for treatment of rabbit bladder infection model, and to offer a new way for prevention and treatment of urinary tract infection.Methods Twenty male New Zealand long-eared white rabbits were divided into gentamicin control group and three different concentrations herba houttuyniae groups according to random number table method, each group 5 rabbits. The rabbit bladder infection model was replicated by injecting coli liquid 1 mL (105 cfu/mL) into the urinary bladder through a urethral catheter, and clipping the catheter for 1 hour. After model establishment for 3 days, in the three herba houttuyniae groups, 0.25, 0.50, 1.00 g/mL herba houttuyniae liquid 50 mL were injected into the bladder respectively, and in the gentamicin control group, 160 kU gentamicin was injected into the bladder. Before molding and after molding for 3, 5, 7, 9 days, ear blood in rabbit was taken, and white blood cell (WBC) count and neutrophil percentage (N%) were tested; at the same time, the middle segment morning urine was taken to detect bacteriuria and urine WBC positive rates; after the experiment, the animals were sacrificed, the urinary bladder tissues were taken, and the pathological changes in urinary bladder tissue were observed by a light microscope.Results Before molding, the bacteriuria in animals of each group was negative and the results of urine WBC, blood WBC and N% were within normal range. After molding for 3 days, bacteriuria and urine WBC positive rates reached 100%; with the prolongation of treatment after molding, the above two rates in each group were gradually decreased, and herba houttuyniae 0.50 g/mL and 1.00 g/mL groups appeared statistical significance on the 5th day (bacteriuria positive rate was 60% and 40%, urine WBC positive rate was 60% and 40% respectively, while the gentamicin control group and herba houttuyniae 0.25 g/mL group was still 100% positive, allP < 0.01); on the 9th day, the bacteriuria positive rate in both higher dosage herba houttuyniae groups was 0, in 0.25 g/mL group, it still had the positive rate 20%, showing herba houttuyniae 0.50 g/mL and 1.00 g/mL had stronger inhibitory effect than herba houttuyniae 0.25 g/mL. WBC and N% were increased in each group after molding, and on the 3rd day, WBC and N were significantly higher in each group than those before molding [WBC (×109/L): gentamicin control group 13.00±5.23 vs. 8.95±2.69, herba houttuyniae 0.25 g/mL group 14.52±10.28 vs. 8.73±3.16, herba houttuyniae 0.50 g/mL group 12.97±11.33 vs. 7.83±4.51, herba houttuyniae 1.00 g/mL group 13.03±9.17 vs. 6.45±3.85. N%: gentamicin control group 80.99±14.93 vs. 63.41±7.96, herba houttuyniae 0.25 g/mL group 89.62±9.41 vs. 70.01±9.13, herba houttuyniae 0.50 g/mL group 87.69±11.34 vs. 67.75±8.91, herba houttuyniae 1.00 g/mL group 85.67±12.81 vs. 65.12±4.63]. On the 7th day, WBC and N% fell, and on the 9th day, the WBC and N% were restored to normal range in herba houttuyniae 0.50 g/mL and 1.00 g/mL groups [WBC (×109/L): herba houttuyniae 0.50 g/mL group 8.56±5.38, herba houttuyniae 1.00 g/mL group 7.93±4.82. N%: herba houttuyniae 0.50 g/mL group 65.97±8.35, herba houttuyniae 1.00 g/mL group 65.57±9.12]. Under light microscopy, it was shown that the morphological appearances of tissue cells in various layers of bladder mucosa were normal in herba houttuyniae group, demonstrating that herba houttuyniae fluid in bladder did not cause allergic inflammatory reaction, etc.Conclusion The bacteriostatic action of herba houttuyniae liquid for bladder irrigation in treatment of rabbits with urinary tract infection is better than that of gentamicin.

Seeds of Bupleurum chinense cultivar, Zhongchai No. 1, were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15, 20, 25, 15-25 degrees C) and light (8,12 h) to germinate, respectively. The lower constant temperature (15 degrees ) and the higher constant temperature (25 "C) were not conducive to the sprouting characteristics of B. chinese. While they were able to enhance root activity to some extent; The seeding growth of B. chinese was significantly better in the variable temperature than correspondence in the constant temperature, significantly. The emergence speed, emergence index, vigor index and root activity of Bupleurum were improved under the 12 h of light-time, but the germination rate was not improved. The sprouting of Bupleurum's seeds could be improved to some extent by soaking with hormone, such as gibberellin, cytokinin, salicylic acid. Gibberellin promoted seeds' sprouting and seedings's root activity of Bupleurum, while salicylic acid increased the root activity of seeding. There is a significant influence of light, temperatures and hormone treatment on the germination of Zhongchai No. 1 seeds, and all three are remarkably interacted; It is beneficial to promote seed germination by the temperature (20 + 5) degrees C, lighting (8 h) and gibberellin concentration (10 x 10(-6)).

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.

BACKGROUND:Stem cel transplantation has gained considerable support recently. It provides new opportunities for treating diabetic neurogenic bladder. OBJECTIVE:To summarize the research progress in bone marrow mesenchymal stem cel s (BMSCs)transplantation in the treatment of diabetic neurogenic bladder. METHODS:The first author retrieved Sciencedirect, PubMed, Embase, Wangfang and CNKI databases, for relevant articles of BMSCs transplantation in the treatment of diabetic neurogenic bladder, published from 2000 to 2016. The key words were“bone marrow mesenchymal stem cel s, diabetic neurogenic bladder, differentiation, transplantation”in Chinese and English, respectively. RESULTS AND CONCLUSION:In patients with diabetic neurogenic bladder, the transplantation of BMSCs may provide safer and longer-lasting outcomes by repairing the damaged bladder and urethra. And it can produce various bioactive substances, which wil have nutritional paracrine effects on the bladder microenvironment, including anti-inflammation, promoting cel proliferation and improving cel survival. On the one hand, the BMSCs have the ability to migrate to the injury site via the blood circulation. On the other hand, BMSCs can produce various growth factors, as wel as the cytokines that can inhibit the inflammatory response. While the current clinical studies are lacking, its efficacy and safety needs further verification.
