OBJECTIVE: To identify a suitable polymer system for iguratimod (T-614), a poorly water-soluble compound with high melting point, and prepare a chemically stable single phase solid dispersion (SD) of T-614 by hot-melt extrusion (HME) technique to enhance its dissolution rate. METHODS: Melting method and adsorption based screening techniques were utilized to screen hydrophilic polymers suitable for immediate release formulations. T-614 SDs were prepared with polymer carriers such as PVP/VA 64, Soluplus, HPMC AS-LF and HPC-SL via HME below the drug melting point, and suitable temperature and plasticizer for HME were chosen. The dissolution behaviors of SD powder and SD tablets were compared with those of T-614 powder and commercial T-614 tablets, respectively. State of T-614 in HME SDs was characterized by X-ray powder diffraction. The homogenous SD tablets were analyzed further for physical stability in an influencing factors test. The bioavailability of SD tablets was assessed in rats. RESULTS: Results of the screening studies demonstrated that PVP/VA 64, Soluplus, HPMC AS-LF and HPC-SL provided higher degree of miscibility and dissolution enhancement. The HWE SD tablets showed significantly enhanced dissolution. The supersaturation state of HME SD powder in water was maintained for at least 120 min, suggesting that PVP/VA 64 had an inhibitory effect on recrystallization of T-614 from a supersaturated solution. Samples prepared via HME at 160°C were substantially amorphous, which were unchanged in the influencing factors test at high temperature and strong light, but recrystallization occurred at high humidity. PEG1500 appeared to be a promising plasticizer. Same bioavailability was achieved when compared with commercial T-614 tablets. CONCLUSION: The polymersas carriers for T-614 SD have significant impact on the dissolution behavior and state of T-614. Using PVP/VA 64 as the carrier, hot-melt extrusion is an effective technology for improving the in vitro dissolution of T-614.

AIM:To evaluate the efficacy and safety of methazolamide in treating refractory uveitic macular edema.METHODS: Retrospective self-controlled study was designed.A total of 15 patients (20 eyes) with refractory uveitic macular edema which used methazolamide as adjuvant therapy were enrolled in Shanghai First People`s Hospital from January 2015 to June 2016.The changes of central macular thickness (CMT) and best corrected visual acuity (BCVA) were observed at baseline and 2, 4, 8wk after treatment.We also focused on the incidence of complications and relapse.RESULTS: The CMT was 445.95±154.10μm, 338.83±138.34μm, 251.50±40.20μm, 244.90±35.68μm at baseline, 2, 4 and 8wk after treatment, respectively.The differences among them were statistically significant (F=15.467, P<0.05).The BCVA (log MAR) were 0.40±0.17, 0.28±0.21, 0.19±0.20, 0.18±0.21 at baseline, 2, 4 and 8wk respectively, with a significant difference among them (F=5.208, P<0.05).When the cumulative dose reached to 700mg and 1400mg, no one had methazolamide-related complications;and when it came to 2800mg, 5 patients (33%) had methazolamide-related complication.After the withdrawal of methazolamide 1wk, 1 and 3mo, 3 patients (20%), 5 patients (33%) and 8 patients (53%) relapsed, respectively.CONCLUSION: Methazolamide is beneficial in improving macular edema and vision in 4wk.When the cumulative dose is more than 1400mg, we need pay attention to the complications.After discontinuing methazolamide for 1wk, macular edema relapsed in some patients, and more than half of patients recurred after 3mo.So the patients should be followed closely in 3mo after withdrawal of methazolamide.

Objective:To study the effects of parathyroid hormone(PTH) upon dentinogenesis by investigating the effects of hPTH1-34 on the development and calcification of parathyroidectomy rats' dentin. Methods: hPTH1-34 were injected into SD rats at different dosages after parathyroidectomy. Six weeks later lower incisors were dissected and prepared for light microscopy and image analysis. Results:The concentration of serum calcium decreased after parathyroidectomy, while increased after being injected hPTH1-34. The results of light microscopy and image analysis revealed the enlargement of the predentinal tubules and the presence of mineralization defects in the PTX group(P

Glaucoma,especially common primary open-angle glaucoma and primary angle-closure glaucoma,shows high genetic heterogeneity. The causing-disease genes known are difficult to explain some glaucomatous cases,and the study on the susceptibial gene of glaucoma do not achieve new breakthroughs. Combined with the newest progression in genetic study of glaucoma,some views were proposed in this paper in order to better understand the updating study of the pathogenesis mechanism.

AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

Objective To investigate the principles of combined traditional Chinese and western medicine treatment of early postoperation inflammatory small bowel obstruction(EPISBO).Methods 93 cases of EPISBO were randomly divided into two groups including group A,47 cases received combined traditional Chinese and west- ern medicine treatment,and group B 46 received only western medicine treatment.Results 93 patients were all cured through nonsurgical treatment.The combined traditional Chinese and western medicine treatment was better in symtom improvement and reduce of expense.Conclusion The principle treatment of EPISBO is mainly nonsurgical. The traditional Chinese medicine and somatostatin are very important.

Only by working out and implementing scientific and rational developmnent strategies can hospitals contend for the initiative and have a leading edge in the fierce market competition. At present, it is imperative for hospitals to develop the new century-oriented market competition strategy in view of their respective current conditions and circumstances, the talent developnent strategy based on the reform of the personnel system, the strategy of scientific and technological development, and the strategy of the socialization of rear services. Hospital managers ought to promote the construction of their hospitals in light of the above strategies. Nevertheless, in implementing hospital development strategies, it is important to guarantee the continuity and stability of the overall development strategies and not to make unpredictable changes. Only by doing so can the development of hospitals be pushed forward via working out hospital development strategies.
