OBJECTIVETo investigate clinical effects of minimally invasive fixation and bone grafting througn medial side for the treatment of Schatzker III tibial plateau fracture.

METHODSFrom April 2009 to August 2011, 18 patients with Schatzker III tibial plateau fracture were treated with minimally invasive fixation and bone grafting through medial side. There were 15 males and 3 females ranging in age from 64 to 73 years, with an average of (69.75 ± 1.22) years. Sixteen patients were caused by falling down, 2 cases were caused by traffic accident. Operative time and length of incision were be recorded. Clinical and radiological follow-up was performed after operation. Hospital for Special Surgery (HSS) score and Kellgren-Lawrence score were used to evaluate clinical effects.

RESULTSThe mean operative time was (45.32 ± 1.58) min, and the mean length of incision was (5.21 ± 0.65) cm. Postoperative X-ray showed excellent reduction. Eighteen patients were followed up for 10 to 13 months with an average of (11.5 ± 1.35) months. The mean HSS score was 86.51 ± 2.71, 12 cases got excellent results,4 good and 2 fair. Three patients were developed mild osteoarthritis according to the Kellgren-Lawrence system.

CONCLUSIONMinimally invasive fixation and bone grafting through medial side, not only could reduce surgical invasive, but also guarantee early function activities. It has advantages of keeping well after reduction. So it has the favorable future in clinic.

A novel drug delivery system combining oral fast dissolving film with sodium deoxycholate/phospholipid mixed micelles was prepared to increase the absorption of cucurbitacin B that is a poor aqueous solubility substance. Encapsulation efficiency, particle size, zeta potential, polydispersity coefficient, investigated the morphology, disintegration time of oral fast dissolving film and the pharmacodynamic properties of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles before and after solidified in mice were evaluated and compared. The oral fast dissolving film prepared in this study showed a homogeneous pale yellow and could completely disintegrated in the 30 s. It could meet the requirements of rapidly disintegrating fully. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles loaded in oral fast dissolving film were (43.36 +/- 2.12)%, (108.82 +/- 5.2) nm, (-34.18 +/- 1.07) mV, 0.088 +/- 0.012, respectively. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles in solution were (41.26 +/- 2.22)%, (181.82 +/- 4.48) nm, (-30.67 +/- 0.81) mV, 0.092 +/- 0.012, respectively. The difference of pharmacodynamics among film of cucurbitacin B-loaded micelles, cucurbitacin B-loaded micelles and free cucurbitacin B in vivo was compared. Solubility of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles has also been greatly improved. The tumor inhibition rate of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles was significantly improved and did not change significantly before and after solidified. These showed that the sodium deoxycholate/phospholipid-mixed micelles could enhance the antitumor activities of cucurbitacin B and the stability of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles was improved significantly after solidified by oral fast dissolving film technology without pharmacodynamic properties changed significantly.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.METHODS: Totally 39 patients (39 eyes) with punctual stenosis were selected from October 2013 to October 2015 in the Second People`s Hospital of Foshan.All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube.These tubes were removed at 3mo after operation.A follow-up of 6mo was taken for final analysis.The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation.The curative effect of the operation at 6mo after the extubation was assess.RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones.The difference was statistically significant(P<0.05).At the last following up, 35 eyes (90%) were cured completely, 4 eyes (10%) were improved significantly, no patients recurred.Effective rate was 100%.No serious intraoperative and postoperative complications happened.CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.

Objective To observe the long term effects of arthroscopic knee debridement and reconstructing operation for treating osteoarthritis in patients with Kaschin-Beck disease. Methods Thirty-one cases of patients with Kaschin-Beck disease were followed for 6 years after operation of articular clearing by arthroscope. Index of pain, symptoms of self-evaluation, range of motion, walking distance, standing test by affected leg when bending at 30° or 60° were recorded and compared with the preoperative results. Results Twenty-four cases were followed up for 6 years. Six years after operation the pain index(3.38 ± 2.87) was dramatically decreased compared to that before operation (6.88 ± 1.45, t = 5.30, P ＜ 0.05). Patients symptoms markedly improved by subjective self-evaluation was 70.83% (17/24), the effective rate was 100% (24/24). The number of cases that could stand up when leg bending at 30° or 60° were 21,18 cases, respectively, compared with that of preoperative of 14, 11 cases, respectively, the difference was statistically significant(x2 = 5.17,4.27, all P ＜ 0.05). Six years after operation the walking distance(3 cases ＜ 1 km, 11 cases 1 - 5 km and 10 cases ＞ 5 km) were greatly improved compared to the results before operation (12 cases ＜ 1 km, 9 cases 1 - 5 km and 3 cases ＞ 5 km, U = 2.88, P ＜0.05). Six years after operation the knee activity[(132.25 ± 14.52)°] remained at the same level, compared with that of preoperative [(131 .58 ± 14.68) °], the difference was not statistically significant (t = 0.16, P ＞ 0.05) .Conclusions The method of arthroscopic joint debridement to cure Kaschin-Beck disease knee osteoarthritis can significantly reduce pain, improve function and walking distance, with more stable long-term satisfactory outcome.
