Background Pseudoexfoliation syndrome (PEX) has a high incidence in Uygur population and usually leads to secondary glaucoma and complicated cataract.The abnormal change of lens tissue and degeneration of zonular fibers bring a lot of difficulties for phacoemulsification (phaco) with intraocular lens implantation,especially stop-and-chop phaco technique.Prechop technique is a new choping technology,but its application in PEX with cataract is less.Objective This study was to compare the efficacy and safety of pre chop phaco technique and stop-and-chop phaco technique for PEX combined cataract.Methods A randomized controlled Clinical trial was designed.Forty-one eyes of 41 patients with PEX combined cataract of Ⅲ degree of nucleus were enrolled in People's Hospital of Hetian District from March 2015 to January 2016.The patients were randomized into the prechop group and stop-and-chop group according to random nubmer table,and cystotome-assisted prechop phaco surgery and stop-and-chop phaco surgery were performed in different groups,respectively.The effective phaco duration,corneal endothelium loss rate,cornea edema eye number after operation,vision outcomes and complications were compared between the two groups.Results The mean effective phaco duration was 14.0 (13.0,16.5) minutes and 18.5 (16.5,24.0) minutes in the prechop group and stop-and-chop group,with a significant difference between them (Z =17.354,P ＜ 0.01).The corneal endothelial cells were (2 101.90 ± 209.08)/mm in the prechop group,and the number was similar to (2 002.30 ± 207.04)/mm of the stop-and-chop group (t =-1.530,P =0.134).Corneal endothelial cell lossing rate was (8.27±2.23)％ in the prechop group,which was lower than (13.09±4.26)％ in the stop-and-chop group (t =3.810,P =0.001).The BCVA was better in the prechop group than that in the stop-and-chop group in postoperative day 3 (P =0.044),and the corneal edema degree was not signigicantly different in postoperative day 1 and day 3 between the two groups (P=0.221,0.446).Intraoperative complication was rapture of zonule and occurred in 1 eye and 2 eyes in the prechop group and stop-and-chop group,respectively.Conclusions Compared with the stop-and-chop phaco technique,the prechop phaco tequnique can decrease intraoperative complication,lighten the postoperative damage of corneal endothelial cells and accelerate visual rehabilitation in PEX combined with cataract patients.

OBJECTIVE: To investigate the therapeutic effect of obstructive sleep apnea hypopnea syndrome (OSAHS) by modified uvulopalatopharyngoplasty (UPPP). METHOD: Forty-nine cases of OSAHS were treated by modified UPPP, and followed-up on 6 months, 1 year and 2 years after operation and carried out polysomnography (PSG) every time. RESULT: Therapeutic effect was evaluated by standard of Hangzhou (2002) . In 6 months, symptoms of snore, breath holding, headache and lethargy disappeared or reduced obviously, the total effective rate was 100%. In 12 and 24 months, the effective rate was 95.92% and 91.84% respectively. CONCLUSION This operation can enlarge venting area of palatopharyngeal cavity effectively and keep density of soft palate as well as the normal function of pharyngeal mucous membrane, and can also elevate operative effect and decrease postoperative complications.

Fifteen compounds were isolated from the seed coat of Juglans regia by silica gel, MCI gel and Sephadex LH-20 gel column chromatography, as well as high preparative performance liquid chromatography. Their structures were identified as salidroside (1), (6S, 9S)-roseoside (2), (6S, 9R)-roseoside (3), blumenol C glucoside (4), byzantionoside B (5), 5-hydroxy-2-methoxy-1, 4-naphthoquinone (6), gallic acid (7), glycerol 1-(9Z-octadecenoate)-2-(9Z, 12Z-octadecadienoate)-3-(9Z, 12Z, 15Z-octadecatrienoate) (8), glycerol 1, 2, 3-tri-(9Z, 12Z-octadecadienoate) (9), glycerol 1, 2, 3-tri-(9Z, 12Z, 15Z-octadecatrienoate) (10), glycerol 1-hexadecanoate-2, 3-di-(9Z, 12Z-octadecadienoate) (11) on the basis of EI-MS, FAB-MS and NMR spectra. Moreover, 35 volatile compounds were identified by GC-MS.

OBJECTIVE: To present the experience of nasal reconstruction with forehead flap. METHOD: nasal reconstruction with forehead flap were applied in eight nasal carcinoma cases after operation and 5 nasal trauma cases with defects. RESULT: These forehead flaps were alive in all patients, all incision healed in I stage, no post operative complications were found. The shapes of nose were satisfactory, there were no recurrence of tumor during 1 to 17 year follow up. CONCLUSION The method can be clinically applied for its simple procedure, reliable flap's blood supply, high survival rate and satisfied result.
