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 investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

Objective To analyze the outcomes of frozen-thawed blastocyst and cleavage embryo transfer after whole embryos cryopreservation. Methods The data of 489 IVF-ET cycles in reproductive medicine center of our hospital from September 2012 to August 2013 were analyzed retrospectively. Whole embryos cryopreservation in 214 patients were carried out with vitrification method and served as group A , 275 cycles performed fresh embryo transfer were served as group B. Then group A and group B were subdivided into group A1 (83 cycles),group A2 (131 cycles), group B1 (120 cycles)and group B2 (155 cycles)according to blastocyst transfer or cleavage-stage embryo transfer. The clinical outcomes of all groups were compared each other. Results The pregnancy rate and embryo implantation rate in group A1 were significantly higher(71.1% ,53.0%)than those in group A2, B1 and B2 (A2 group: 57.3%, 34.0%, B1group: 55.0%,42.1%, B2 group: 52.9%, 32.7%,respectively)(P<0.05). The embryo implantation rate in group B1 were higher than those in group B2 (P < 0.05). Conclusion F-ET after whole embryos freezing could significantly improve the embryo utilization rate and clinical pregnancy rate. Frozen-thawed blastocyst transfer could get better clinical outcomes than frozen-thawed cleavage-stage embryo transfer.

Objective To evaluate the clinical value of frozen-thawed blastocyst transfer and the blastocyst derived from frozen-thawed cleavage stage embryo transfer.Methods The data of 5 1 8 cycles in reproductive medicine center of the hospital from Sep-tember 2012 to August 2013 were analyzed retrospectively.According to the frozen-embryos type,all patients were divided into three groups,group A:frozen-thawed blastocyst transfer,129 cycles;group B:blastocysts derived from frozen-thawed cleavage stage embryos transfer,123 cycles;group C:frozen-thawed cleavage embryos transfer,266 cycles.The clinical outcomes of all groups were compared with each other,and the rates of blastocyst formation and cancellation were compared between group A and group B.Re-sults The rates of biochemical pregnancy,clinical pregnancy and embryo implantation in group A(70.5%,61.2%,42.3%)and group B(67.5%,58.2%,40.2%)were significantly higher than group C(53.0%,42.5%,23.1%)(P<0.05);there were no signif-icant differences in the rates of early abortion,ectopic pregnancy,multiple pregnancy among three groups(P>0.05);there were no significant differences in the blastocyst formation rates of the high quality cleavage embryos at D3 in fresh cycles and the frozen-thawed cleavage embryos(62.5%vs.57.7%)(P>0.05)and those two groups were both significantly higher than the poor quality cleavage embryos at D3 in fresh cycles(20.3%)(P<0.05).Conclusion Blastocyst transfer in vitrified-thawed cycles could get rel-atively satisfactory clinical outcomes.There are higher blastocyst formation rate and better clinical outcomes of transfer blastocyst derived from frozen-thawed cleavage embryo.

Objective To explore a simple and convenient method for the treatment of penis skin defect.Methods Since Jan.1995,the scrotal skin flaps have been used to repair the defects of the penis skin in 8 patients with penis skin infection.6 of these cases lost their whole penis skin,and 2 of them lost 2/3 of their penis skin.The granulation tissues in the defective area of penis skin were cut away,and then the normal aponeurosis of corpus cavernosum or spongiosum exposed.The scrotal skin flaps were designed and shaped.The flaps were transferred to cover the defects,and the incisions were closed.Results All the flaps in 8 cases survived completely.The follow-up period was 3 to 12 months after operation.All cases obtained satisfactory results to the contour and function of the penises.Conclusion This procedure is a much better method for repairing skin defects in the penis.It can be easily operated and completed in one-stage.The postoperative results are satisfactory.

The tongue and its surrounding structures have special anatomical and functional characters and how to restore its shape and function after glossectomy (especially total glossectomy) still remains a difficult problem. The authors devised a new method of repair by using a forearm free flap with results in 16 out of 17 patients. The selection and shaping of the flap, the evaluation of the recipient site and its blood vessels, the prevention of the oral infection,the monitoring of the circulatory status of the flap and the evalution of the operative result were discussed.

Objective To summarize the diagnosis and treatment experience for patients with appendiceal carcinoid tumors.Methods 21 patients with appendix carcinoid tumors were admitted and received surgery from 1967 to 1997 in our hospital.Results 12 patients (57%) presented with signs and symptoms suggestive of acute appendicitis.In 9 patients(43%) tumors were discovered incidentally.The tumors were at the tip in 17 patients,at the middle third in 3,and at the base of the appendix in one.The tumor was less than 1 cm in diameter in 16 patients,between 1 and 2 cm in 3 patients,and larger than 2 cm in 2 patients.Tumor invasion was confined to the submucosa or muscle layers in 15 patients,serosa involved in 4 patients,and into the meso appendicular fat in the remaining 2 patients.Twenty patients underwent appendectomy alone.One patient with a tumor size larger than 2 cm and positive lymph nodes in the mesoappendix underwent secondary right hemicolectomy.Complete follow up was achieved in 19 patients,and all patients remained free of tumor recurrence and metastasis.Conclusion Appendiceal carcinoids of less than 1 cm could be adequately managed by appendectomy alone.The appropriate treatment for tumors of 1 to 2 cm are still controversial.Right hemicolectomy is recommended for tumors larger than 2 cm .
