Objective To study the pharmacokinetic characters of cyclosporin A(CsA) in aqueous humor in rabbit after implanting different dosages of CsA in eyes and to provide a theoretical basis for the treatment of after cataract. Methods ECCE was performed in all rabbit eyes. CsA-MS was injected into the anterior chamber and the capsular bag in left eyes as expression group and MS was given in the same way in right eyes as control group. The concentration of CsA in the aqueous humor was monitored with high-performance liquid chromatogram. The follow-up period was 4 weeks. The samples were separated on a C18 column at 60℃ and detected at 210nm. The mobile phase was acetonitrile-water (67∶33). Results The correlation analysis showed a positive correlation within the range of 0.13-1.25mg/L (r=0.9951) and the detection limit was 0.13mg/L. The accuracy was 95.91% and the inter-day and intro-day precision was less than 5%. CsA in aqueous humor sustained a high concentration within 2 weeks. There were no significant differences in t1/2Ka and CL between the two dosage groups. AUC and Cmax increased in a dose-dependent manner. Conclusion The sustain-released CsA ophthalmic gels provided significant ocular bioavailability in rabbit eyes and they can reach the therapeutic dose in order to inhibit after cataract.

BACKGROUND:Studies have shown that the vacuum sealing drainage technology can effectively promote the wound healing, and it has a wide prospect of clinical application, but there are few reports addressing the
treatment of diabetic foot.
OBJECTIVE:To discuss the clinical effect of vacuum sealing drainage technology in the treatment of diabetic foot wounds.
METHODS: Sixty diabetic foot patients were randomly divided into two groups: traditional treatment group,
regulating blood sugar level, dressing and traditional debridement; vacuum sealing drainage group, conventional treatment combined with the vacuum sealing drainage technology. The clinical efficacy of two treatments for
diabetic foot was evaluated.
RESULTS AND CONCLUSION: Compared with the traditional treatment group, the vacuum sealing drainage
showed better outcomes in switching frequency, stable blood sugar control, preparation time, wound healing time and cure rate (P < 0.05). It indicates that the vacuum sealing drainage technology in the treatment of diabetic foot ulcers can resolute wound inflammation, stimulate the growth of granulation, create a favorable surgical condition for secondary skin grafting or flap coverage, significantly shorten the treatment time, and exhibit better curative effects than the traditional treatment.

Objective:Plerixafor,an analog of C-X-C motif chemokine receptor 4(CXCR4),which allows the release of stem cells from the bone marrow into peripheral blood(PB)by disrupting the interaction of CXCR4 with stromal cell-derived factor-1(SDF-1),is effective in mobilization for peripheral blood stem cells(PBSC).Due to its market approval has not been long and its high price in China,the clinical application of plerixafor is still very limited.The clinicians are actively seeking the optimal use of plerixafor to improve the success rate of PBSC collection and reduce the cost.This article reviews the latest research progress related to plerixafor application,in order to summarize the optimal use of plerixafor in autologous hematopoietic stem cell transplantation(auto-HSCT).

Acetabular is an important human joint for weight bearing. Quadrilateral plate is a crucial structure of medial acetabulum with special morphology and important function. Quadrilateral plate fractures are common fracture in acetabulum. Quadrilateral plate fracture is hard to expose and reduction because it is in the medial of acetabulum. At the same time,the bone in the quadrilateral plate is not easy to fixed for thinning bones and adjacent to the articular cavity. The operator should know well about the anatomy and choose the suitable internal fixation. After quadrilateral plate fractures, the femur head maybe displace medially even break into pelvis. That make reduction and treatment always be a challenge. With different kinds of fractures,the efficacy of treatment is not the same. This paper intend to review the relation of anatomic features,approaches, internal fixations, key point of treatment and efficacy.

Objective To observe the protective effect of ulinastatin (UTI) on the intestinal barrier function of septic rats.Methods Septic rat model was established using Sprague-Dawley rats by cecal ligation and puncture (CLP) method.Thirty Sprague-Dawley rats were randomly divided into 3 groups (n =10 for each grop) : sham group, septic group and UTI group.All rats received intraperitoneal injections of 0.9％ saline (10 mL/kg) after and 8 h after surgery.In UTI group, UTI (10 × 104 U/kg in 10 mL/kg saline) was injected after and 8 h after surgery.Collect blood samples after 0, 8, 12 h after surgery to examine levels of procalcitonin (PCT), intestinal fatty acid binding protein (iFABP) and diamine oxidase (DAO) by enzyme-linked immunosorbent assay (ELISA) method.Rats were killed 12 h after surgery to collect intestine tissue samples.Pathological changes of intestine were observed under microscopy, and the expression of tight junction protein-1 (ZO-1) and occludin were analyzed by Western blot.Results In sham group, the mucosa structure was complete and the shape was normal, and villi stood neatly.In septic group, intestinal was expanded, intertinal mucosal was atrophic, villi were scanty.An inflammatory infiltrate with numerous nuetrophils was found in the mucosal.In UTI group, the level of severity was relatively slight.The relative optical density of Western blot images were decreased on ZO-1 and occludin in CLP and UTI groups, and decreased more in CLP group (F =43.15 and 52.23, P ＜ 0.05).At 0h after surgery, the plasma values of PCT, iFABP and DAO were similar in three groups (F =11.17, 22.45 and 13.58, P ＞ 0.05).At 8h and 12h after surgery, values of PCT, iFABP and DAO in septic and UTI groups were much higher than those in the sham group, and those in UTI group were also significantly higher than those in septic group (F8h=85.26, 44.59 and 101.47, F12h =59.44, 49.26 and 69.57, all P＜0.05).PCT, iFABP and DAO levels were first increased and then fell down in sham group, those in septic group were keeping increasing, and those in UTI group were first increased and then kept stable.Conclusion UTI shows protective effect to intestinal barrier function in rats with sepsis.

Objective To investigate the effects of hippocampal?sparing intensity?modulated radiotherapy ( IMRT) on dose distribution of target volume and organs at risk ( OARs) in locally advanced nasopharyngeal carcinoma. Methods A retrospective dosimetric analysis was performed among 11 patients with locally advanced nasopharyngeal carcinoma. The MONACO ? v5. 10 Treatment Planning System was used to design three treatment plans:routine volumetric modulated arc therapy ( VMAT ) , hippocampal?sparing VMAT, and nine fixed?fields IMRT. The D98%, D50%, D2%, Dmean , conformity index ( CI ) , and homogeneity index (HI) of planning target volume (PTV) and PTVnx as well as dose distribution of the hippocampus and OARs were evaluated. Using single factor analysis of variance,two group comparative was LSD or paired t?test. Results For the above three plans,the D2% values of PTVnx were ,7 513,and 7 462 cGy,respectively (P=0. 016);the D98% values of PTV were 5837,5812,and 5914 cGy,respectively (P=0. 029);the average D2% values of PTV were 7 399,7 380,and 7 333 cGy,respectively ( P=0. 047);the HI values of PTV were 0. 239,0. 241,and 0. 220,respectively (P=0. 016);the V10 values of the brain stem were 97. 2%,88. 1%,and 90. 3%,respectively ( P=0. 001);the V20 values of the brain stem were 74. 2%, 62. 3%,and 67. 1%,respectively ( P=0. 032);the V30 values of the brain stem were 50. 9%,35. 8%,and 45. 5%, respectively ( P= 0. 020 );the V40 values of brain stem were 24. 4%, 14. 4%, and 23. 3%, respectively ( P=0. 018);the Dmean values of hippocampus were 1 518,899,and 896 cGy,respectively ( P=0. 000);the D40% values of hippocampus were 1 379,642,and 639 cGy,respectively ( P=0. 000);the V10 values of the hippocampus were 54. 1%,25. 1%,and 3. 8%,respectively ( P=0. 000);the V20 values of the hippocampus were 26. 2%, 12. 6%, and 12. 0%, respectively ( P=0. 001 ) . Conclusions Hippocampal?sparing VMAT and nine fixed?fields IMRT can significantly reduce the dose to the hippocampus without affecting dose distribution of target volume and OARs. VMAT may be superior to IMRT because VMAT can simultaneously reduce the dose to the brain stem.

ObjectiveTo evaluate the clinical efficacy of acupuncture at Waiguan (TE5) and Zhigou (TE6) in treating post-stroke hand spasm.MethodSixty patients with post-stroke hand spasm graded≥Ⅰand≤Ⅲby the Modified Ashworth Scale (MAS) were randomized into a treatment group (30 cases) and a control group (30 cases). The treatment group was intervened by acupuncture at Waiguan and Zhigou plus rehabilitation training, while the control group was by dry rehabilitation training alone. The acupuncture and rehabilitation were performed once a day, 5 sessions a week, totally for 3 months. The change of hand spasm degree was observed by using MAS; the Fugl-Meyer Assessment (FMA) was adopted to observe the change of hand function; the Modified Barthel Index (MBI) was used to observe the change of the activities of daily living (ADL).ResultAfter treatment, there was a significant difference in comparing the MAS score between the two groups (P<0.05); there was a significant difference in comparing the FMA score between the two groups after treatment (P<0.05); after intervention, there was a significant difference in comparing the MBI score between the two groups (P<0.05).ConclusionAcupuncture at Waiguan and Zhigou can significantly improve the hand spasm sate after stroke; acupuncture plus rehabilitation can substantially improve the hand function and ADL of the patients, and can produce a more significant efficacy compared to dry rehabilitation training.
