@#AIM: To investigate the postoperative visual acuity and ophthalmic complications after phacoemulsification in cataract patients with acquired immunodeficiency syndrome(AIDS). <p>METHODS: We enrolled 47 eyes of 33 patients with AIDS who underwent phacoemulsification and intraocular lens implantation in our department between May 2016 and April 2019. The visual acuity, diopter, intraocular pressure(IOP), anterior chamber cell count(ACCC), and postoperative complications were recorded postoperative 1d, 1wk, 1mo, and 3mo.<p>RESULTS:The postoperative visual acuities, including uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)at postoperative 1d, 1wk, 1mo, and 3mo, were significantly better than that of preoperation(<i>P</i><0.05). The ACCC count on the first day after surgery increased as compared with preoperation, but the difference was not significant from the first week after surgery. Furthermore, there was no apparent ophthamolic complications occurred after surgery. <p>CONCLUSION: The phacoemulsification and intraocular lens implantation is a safe and effective surgery for cataract patients with AIDS.

Evaluation of diopter after cataract surgery in high myopia combined cataract / 国际眼科杂志(Guoji Yanke Zazhi)

To observe the diopter after cataract surgery for vision gain in high myopia and its effect on visual outcomes.METHODS: Sixty ( 120 eyes ) high myopia combined with cataract cases received phacoemulsification and intraocular lens implantation in our hospital were retrospective studied. The patients were divided into three groups based on postoperative diopter: -1. 0 ~ -2. 0D (group A), -2. 25~-3. 0D (group B) and -3. 25 ~-4. 0D ( group C ) . The uncorrected distance visual acuity ( UCDVA) , best corrected distant visual acuity ( BCDVA) , uncorrected near visual acuity ( UCNVA ) and questionnaire of Activities of Daily Vision Scale ( ADVS ) were collected to assess the vision gain at 3mo after cataract surgery.RESULTS: At 3mo after surgery, UCDVA of group A was better than that of group B, and UCDVA of group B was better than that of group C. There were no differences in BCDVA among groups. There were significant differences between the three groups' UCNVA, it was best for the group C, followed by the group B, group A was the worst. For questionnaire, no difference was observed in patients' satisfactory for surgical results, but a significant difference was detected in postoperative glasses wearing frequency between groups.CONCLUSlON: For cataract surgery in high myopia combined cataract, postoperative diopter should be calculated based on patients' daily requirements. For patients had not used to wearing glasses and near distant working condition, it's appropriated to reserve a minor degree of myopia. Conversely, for patients require near distant working and received wearing moderate and low hyperopia mirror, higher degree of myopia can be reserved.

Relativity of commercial specification of Menthae Herba based on chemical analysis / 中国中药杂志

In order to compare the differences of 35 Menthae Herba samples collected on the market and at producing areas, the contents of six total terpenoids, the essential oil and chromatographic fingerprints were analyzed, which provided evidences for drawing up the commodity specifications and grading criteria of Menthae Herba. GC-MS method was used to analyze the chemical constituents of 35 different samples. The chromatographic fingerprints obtained by using GC were then evaluated by similarity analysis, hierarchical clustering analysis and principal component analysis. The relativity between the content of six terpenoids and the essential oil were studied. In this study, the chemical profiles of 35 samples from different producing areas had significant disparity. All samples collected in the report could be categorized into four chemical types, L-menthol, pulegone, carvone and L-menthone, but the chemical profiles had no relationship with the areas. The chromatographic fingerprints of the samples from different types were dissimilar, while the different producing areas were difficult to be separated. It was indicated that the content of volatile oil was positively correlated with the content of L-menthol and the sum of six total terpenoids. The content of the essential oil, L-menthol and the sum of six total terpenoids of Menthae Herba were considered as one of the commercial specifications and grading criteria. These results in the research could be helpful to draw up the commercial specification and grading criteria of Menthae Herba from a view of chemical information.

Study on content of iodine in food in Tianjin market and iodine nutrition conditions among college students / 中华预防医学杂志

<p><b>OBJECTIVE</b>To know about content of iodine in foods sold in Tianjing markets presently, and the iodine nutrition conditions in college students. It was also aimed to probe the functions of the iodized salt complement with the dietary iodine intake, and whether the urine iodine could reflect dietary iodine intake.</p><p><b>METHODS</b>278 food samples in markets were collected by a randomly stratified sampling method, while the arsenic-cerium catalytic contact method was used to determine the content in food. The dietary information of students for seven days was recorded, and the urine iodine was determined through the arsenic-cerium catalytic spectrophotometry.</p><p><b>RESULTS</b>The determination of 47 kinds and 278 food samples indicated that the content of iodine within animal foods (7.8 microg/100 g - 30.8 microg/100 g) was higher than that within plant foods (1.8 microg/100 g - 16.1 microg/100 g). The investigation also showed that students who regarded vegetarian food as principle accounted for 70. 19%. The amount of dietary iodine intake among those students, based on the dietary survey, was (111.67 +/- 53.18) microg/d, while supplementary iodine from iodized salt was about (230.27 +/- 45.55) microg/d. Therefore, the total iodine provided from diet would be (341.95 +/- 89.58) microg/d. Modified by urine creatinine, the median of urine iodine was 271.28 microg/gCr, and the urine iodine and dietary iodine intake was found positively related (r(s) = 0.463, P < 0.01).</p><p><b>CONCLUSIONS</b>Regarding the vegetarian food as the principle, most of students investigated are not rich. The dietary iodine intake is lower than RDA (150 microg), but it can be obtained the iodized salt by 230. 27 microg, which is the possible supplement to the shortage from foods.</p>
