ABSTRACT
AIM: To analysis of cataract prevalence and operation status in people aged 65 years old in the eastern Fengxian of Shanghai.?METHODS:In the period of January to December 2015, random stratified sampling in the whole group was taken in 3050 people over 65 years, in Situan and Fengcheng, two towns at the Eastern District of Fengxian Town. Ophthalmologic examination and questionnaire survey were given to those people, including slit lamp microscopy and visual acuity ( LogMAR ) and the conditions on cataract surgery.?RESULTS: Totally 1244 cases of cataract were found in 3050 subjects, the prevalence rate was 40. 79％. The prevalence rates in the subjects of different ages were different, as the age increases, the prevalence rate was rising. The difference of prevalence rate in different age groups was statistically significant (x2=558. 6, P<0. 001);the prevalence rate of male and female were 31. 06％ and 49. 94％, the difference was statistically significant ( x2 =112. 4, P<0. 001 ); the rate of illiterate and literate was 52. 04％ and 38. 76％ respectively with significantly difference (x2 = 28. 78, P<0. 001). Cataract surgery was taken in 765 cases, surgical coverage rate was 61. 25％;difference on age, gender was not statistically significant;the degree of education: the rate in literate was significantly far higher than in the illiterate, the difference was statistically significant ( x2 = 39. 72, P < 0. 001 ). Postoperative corrected visual acuity ≥ 0. 3 was considered as removing from disable and postoperative corrected visual acuity≥0. 05 as removing from the blind. The rate removing from disable was 71. 50％, the rate removing from the blind was 95. 29％. In 765 eyes receiving surgery, postoperative complications occurred in 29 eyes, 3. 79％ of the total eye receiving surgery.?CONCLUSION: Cataract is the common blind causing disease in the elderly, and the prevalence rate of cataract in eastern Fengxian of Shanghai is high. Although in recent years, the Restoring Vision Project has been developed, the surgical coverage has been improved, and the prevention and control of cataract is still the primary task of blind prevention.
ABSTRACT
To evaluate the clinical efficacy and safety of tripterygium glycosides (TG) in the treatment of henoch-schonlein purpura nephritis(HSPN). Seven English and Chinese databases (up to Nov. 9, 2017), were searched to collect the RCTs on TG for HSPN. Two researchers independently screened the literature according to inclusion criteria and exclusion criteria, extracted data, and evaluated the quality of the literature. After completion, cross-checking was performed and Meta-analysis was performed using RevMan 5.3 software. At the same time, different outcomes of the interventions were analyzed subgroupically. A total of 46 RCTs were included, with 1 659 in the experimental group and 1 596 in the control group. All the clinical studies showed a low quality. In terms of complete remission rate, the group with TG performed better than the group with conventional therapy or GC（RR=1.82，95%CI[1.39，2.39];RR=2.03，95%CI[1.37，2.99]），the group with TG+GC performed better than the group with GC（RR=1.46，95%CI[1.32，1.60]），and the group with CTX+GC performed better than the group with TG+GC（RR=0.35，95%CI[0.16，0.75]）. In terms of total effective rate, the group with TG performed better than the group with conventional therapy or GC（RR=1.44，95%CI[1.19,1.74];RR=1.30，95%CI[1.16，1.46]），the group with TG+GC performed better than the group with GC（RR=1.27，95%CI[1.21，1.34]），and the group with CTX+GC performed better than the group with TG+GC（RR=0.60，95%CI[0.43，0.85]）. No significant difference was found between the group with TG+GC and LEF+GC（RR=0.68，95%CI[0.30，1.53]）. In terms of urinary protein, urine occult blood negative time，the group with TG performed better than the group with conventional therapy（MD=-9.00，95% CI[-11.99，-6.01];MD=-12.00，95%CI[-16.13，-7.87]），the group with TG+GC performed better than the group with GC（MD=-8.86，95%CI[-10.08，-7.64];MD=-16.24，95%CI[-23.80，-8.67]）. In terms of recurrence rate, the group with TG+GC was lower than the group with GC（RR=0.13，95%CI[0.06，0.25]）, but there were no significant difference between the group with TG and conventional therapy（RR=0.43，95%CI[0.15，1.19]）. In adverse reactions, the common adverse effects of TG were gastrointestinal discomfort, liver damage and leucopenia. TG for the treatment of HSPN can improve clinical efficacy, reduce recurrence, and the adverse reactions are relatively safe. Due to the generally low methodological quality of the included studies, which affected the accuracy and reliability of the result. Therefore, more high-quality, large samples and multi-center randomized controlled trials are necessary for further evidence.
