Objective:To analyze the disease burden of Parkinson's disease (PD) in China from 1990 to 2021 and predict the disease burden of PD from 2022 to 2030.Methods:Based on the data of PD incidence in China from the Global Burden of Disease Study 2021 (GBD 2021), changes in PD disease burden from 1990 to 2021 were analyzed. Age-period-cohort model was used to analyze the independent influences of age, period and cohort in PD incidence (according to age group of 5 years, patients were divided into 15 groups: group of 20-24 years, group of 25-29 years..., and group of 90-94 years; according to a 5-year period, patients were divided into 6 groups: group of 1992-1996, group of 1997-2001..., and group of 2017-2021; because of birth cohort=period-age, patients were divided into 20 birth cohorts: birth cohort of 1897-1906, birth cohort of 1902-1911..., and birth cohort of 1992-2001). Nordpred model was used to predict the disease burden of PD from 2022 to 2030.Results:(1) From 1990 to 2021, number of PD patients, and PD incidence and standardized incidence in China showed upward trends. The standardized incidence increased by 89.68% for the total population, 89.71% for males, and 77.64% for females. (2) PD incidence was low in young subjects and increased obviously in subjects aged 60 years. PD incidence in subjects aged 20-24 years or 90-94 years was 0.07/100 000 and 643.31/100 000, respectively. Compared with female subjects, male subjects aged 60-94 years had higher PD incidence. (3) The onset relative risk increased from 0.71 (95% CI: 0.69-0.73) in group of 1992-1996 to 1.17 (95% CI: 1.16-1.19) in group of 2017-2021 in the total population, increased from 0.68 (95% CI: 0.66-0.70) to 1.18 (95% CI: 1.16-1.21) in males, and increased from 0.75 (95% CI: 0.73-0.77) to 1.14 (95% CI: 1.12-1.16) in females. (4) Onset relative risk was 0.40 (95% CI: 0.33-0.48) in the earliest birth cohort (1897-1906), which increased to 1.81 (95% CI: 0.95-3.43) in the latest birth cohort (1992-2001). (5) Number of PD patients in males, females and total population in China would increase to 455 010, 301 173 and 756 183, respectively, and the standardized incidence would increase to 56.45/100 000, 32.28/100 000 and 43.40/100 000, respectively, till 2030. Conclusion:PD disease burden in China from 1990 to 2021 is severe, particularly among males and the elderly; the disease burden is projected to continue rising up till 2030.

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 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.

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.
