Objective: To study the quality and transdermal properties of matrine microemulsion-based hydrogel (MBH) to provide basis for the development of the preparation.Methods: The stability of MBH was observed at 4 ℃ for 3 months and the changes of particle appearance, viscosity, pH and matrine content were observed.The transdermal permeation of MBH was investigated by a dual chamber permeation and diffusion device with excised mouse skin as the barrier.Taking rabbits as the experimental subjects, the irritation of MBH to the normal skin and damaged skin was investigated.Results: The appearance, viscosity, pH and matrine content of MBH at 4 ℃ in 3 months did not change significantly.In vitro transdermal test showed that MBH had a good penetration rate on mouse skin, and no skin irritation occurred after single or multiple administrations.Conclusion: MBH has good stability and high rate of transdermal penetration without skin irritation, which is a promising drug delivery system of matrine with good application prospects.

Objective To investigate the relationship between CIDE-B change and apoptosis by detecting expression of CIDE-B gene and protein under various injuring conditions(firearm injury and in- cision injury)and comparing neuronal apoptosis.Methods A total of 108 New Zealand rabbits were randomized into firearm injury group,incision injury group and control group.Samples were harvested at different time points after injury for measuring CIDE-B mRNA expression level by RT-PCR,demonstrating morphological distribution of CIDE-B mRNA by in situ hybridization and determining CIDE-B protein level by Western blot.Results Following nerve injury,CIDE-B mRNA expression in spinal cord was en- hanced markedly in the firearm injury group,increased from at day 1,reached peak at day 7,lasted for two weeks and declined after four weeks.CIDE-B mRNA expression was increased late,with small range in the incision injury group.The changes in CIDE-B protein level accorded with those in CIDE-B mRNA level.There was slight CIDE-B mRNA expression,distributing in spinal cord neuronal cytoplasma,in spinal cord tissues in the control group.Conclusions Following peripheral nerve injury,expressions of CIDE-B mRNA and protein are enhanced in spinal cord neurons and distributed in the grey matter of spi- nal cord.Such enhancement is more marked after firearm injury than incision injury.

Objective To summarize the features of esophageal hiatus hernia (EHH) on contrast-enhanced ultrasound (CEUS) and investigate the diagnostic value of CEUS in EHH.Methods A retrospective analysis of 88 EHH patients and 50 healthy controls was conducted with focus on their findings on CEUS.Results The structures of the cardiac and abdominal esophagus were clear in 50 healthy controls,and the esophageal hiatus diameters were (1.96±0.39) cm.In contrast,the cardiac and abdominal esophagus in EHH patients were unable to be identified in subdiaphragm region.The esophageal hiatus was wider with a diameter of (3.24±0.76) cm.The difference was statistically significant(t=2.36,P＜0.05).The hernia sacs were found in 78 EHH patients at rest.And the hernia sacs were present on the diaphragm in 10 EHH patients after pressure.The maximum diameter of hernia sac was 7.6 cm.The size of hernia sac may change with abdominal pressure.In sliding EHH patients,the sac wall was found to slide up and down the diaphragm.A mass was found on the wall in 2 patients.The B ring was present in 76 patients.For healthy controls in supine position,contrast-enhanced ultrasound showed that the gastric bottom and diaphragm were at dependent or horizontal position.The gastric bottom and diaphragm was upward in 73 patients.Conclusions The EHH has characteristic appearance on CEUS.It is easy to detect and diagnose EHH with CEUS,which has a diagnostic value in detection of space-occupying lesions in hernia sac.CEUS can be used for EHH screening.

AIM: To report a two- year's results of iontophoresis-assisted transepithelial corneal cross-linking (I-CXL) for progressive keratoconus.
METHODS: Thirty - four eyes in 24 patients with progressive keratoconus ( mean age 21. 0 ± 5. 6 years;range: 14-32 years) were treated. After 1g/ L riboflavin-distilled water solution was administered by iontophoresis-assited (current 1mA) transepithelial method for 5min in total, standard surface UVA irradiation ( 370nm, 3mW/cm2 ) was performed at a 1 - cm distance for 30min. The best corrected visual acuity ( BCVA ) measured as LogMAR number, corneal refractive astigmatism, K1, K2, Kmean, Kmax, intraocular pressure, endothelial cell density, the thickness at corneal apex and the thinnest point were measured preoperatively and 2a postoperatively.
RESULTS:At 2a after the procedure, BCVA (LogMAR) improved from 0. 32 ± 0. 25 to 0. 25 ± 0. 19 ( t = 2. 849, P =0. 015). K1 decreased from 47. 12±4. 33 to 46. 06±4. 77 (t =2. 652, P= 0. 015). K2 decreased from 51. 36±5. 59 to 50. 40±6. 16 (t= 2. 121, P= 0. 047). Kmean decreased from 49. 12±4. 76 to 48. 10±5. 25(t = 2. 663, P = 0. 015). Kmax decreased from 57. 57±8. 30 to 55. 91±8. 14 (t = 2. 398, P = 0. 026). The corneal apex thickness decreased from 476. 90±38. 71μ m to 454. 43 ± 40. 86μ m ( t = 2. 853, P = 0. 010 ). The thinnest thickness decreased from 464. 38 ± 39. 92μ m to 433. 86 ±50. 78μ m ( t = 3. 485, P = 0. 002 ). Corneal refractive astigmatism, intraocular pressure and endothelial cell density did not show significant changes.
CONCLUSION: I - CXL for progressive keratoconus is safe and effective which can prevent deterioration of progressive keratoconus within 2a, but further long-term studies are necessary still.

Objective To study the effect of exogenous prostaglandin E 1 (PGE 1) on the superoxide dismutase(SOD) and nitric oxide(NO) levels in brain tissue of neonatal rats with hypoxic-ischemic brain damage(HIBD).Methods Sixty 7-day old newborn Wistar rats to establish HIBD models,intraperitoneally and subcutaneous injected PGE 1 and TMP,then the rats were killed after hypo- xia and ischemia for 48 hours.Take cerebral cortex of arteria carotis ligation side and made them into homogenate to detect SOD and NO levels in brain tissue.Results SOD level in HIBD group was lower,and NO level was higher than those of normal group(P

Objective To study the association between functional genetic polymorphisms of IL-1B(T-31C,C-511T),IL-1RN and the susceptibility to gastric cancers. Methods A case-control study was conducted in 180 gastric cancer cases and 308 age-and sex-matched cancer-free controls.Genotypes were detected by PCR-restriction fragment length polymorphism(PCR-RFLP) assays,and association between genotypes,environmental factors and risk of gastric cancers were determined. Results IL-1B T-31C was in strong linkage disequilibrium with IL-1B C-511T(D'=0.862,R2= 0.721,P=0.000).Multivariate logistic regression analysis revealed that the variant genotypes of IL-1B T-31C and C-511T were not significantly associated with risks for gastric cancers(adjusted OR,0.95 and 95% CI,0.62-1.47 for IL-1B T-31C;and adjusted OR,0.85 and 95% CI,0.55-1.31 for IL-1B C-511T).The variant genotypes(1/2,2/2) in IL-1RN were associated with a non-significantly increased risks for gastric cancers(adjusted OR,1.32 and 95% CI,0.71-2.36) in all subjects and with a significantly increased risks for gastric cancers in subjects with H.pylori infection(adjusted OR,2.03 and 95%CI,1.02-4.80).Conclusion The functional genetic polymorphisms of IL-1RN may contribute to the risks of gastric cancers in high-risk population,particularly in those with H.pylori infection.
