Résumé
AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P<0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃~15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

<p><b>BACKGROUND</b>Trabeculectomy has become a mainstream treatment in intraocular pressure (IOP) reduction for primary angle-closure glaucoma (PACG); combined trabeculectomy and cataract surgery was reported to reduce IOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract.</p><p><b>METHODS</b>This is a comparative case series study. Thirty-one patients (31 eyes) with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone. IOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final IOP less than 21 mmHg without IOP-lowering medication.</p><p><b>RESULTS</b>After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding IOP reduction ((20.59 ± 7.94) vs. (24.85 ± 14.39) mmHg, P = 0.614), complete success rate (88% vs. 71%, P = 0.370), formation rate of functioning blebs (65% (11/17) vs. 93% (13/14), P = 0.094), and complications (41% (7/17) vs. 57% (8/14), P = 0.380). IOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group.</p><p><b>CONCLUSION</b>Phacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.</p>

Objective To compare the prevalence rate of metabolic syndrome(MS)using the criteria of Chi- nese Diabetes Society(CDS)or International Diabetes Federation(IDF)in hypertension patients in China.Methods The prevalence of MS in hypertension patients(n=17861)in China and its relations with age,gender and levels of blood pressure were studied.Results 1)the prevalence of MS in hypertension patients was 42.2 % or 46.3 %,ac- cording to the definition of CDS or of IDF.The diagnostic rate of the definition of IDF was higher(P80 years group,the diagnostic rate by IDF definition was slightly but significantly higher in all ages groups(P0.05),on contrary,the female prevalence was increased while the male prevalence decreased by IDF. The prevalence of MS increased with levels of blood pressure by both definition.4)The prevalence rate was in- creased with the elevation of BP,compare with CDS criteria the diagnostic rate of MS was slightly higher by IDF cri- teria in all levels of BP.Conclusion Compared with the definition of CDS,the diagnostic rate of MS by the defini- tion of IDF was higher in hypertension patients,addressing more aggressively control global risk factors.

<p><b>OBJECTIVE</b>To investigate the relationship of insulin resistance and the polymorphisms of insulin receptor-related genes in essential hypertension patients of two different kinds of TCM constitution.</p><p><b>METHODS</b>Oral glucose tolerance test (OGTT) and insulin release test (InRT) were conducted in 217 essential hypertensive patients of either sluggish meticulous (SM) constitution (139 cases) or prosperous impetuous (PI) constitution (78 cases), and the polymorphism of three genes, including insulin-like growth factor-1 receptor (IGF-1R), insulin receptor substrate-1 (IRS-1) and 2 (IRS-2) genes were detected.</p><p><b>RESULTS</b>(1) OGTT, InRT and insulin resistance index (Homa-IR) were higher and insulin sensitive index (ISI) was lower in the patients of SM constitution than those in patients of PI constitution. (2) Significant difference of ISI and Homa-IR was shown in patients of both constitutions with genotype G of the 3 genes.</p><p><b>CONCLUSION</b>Decrease of insulin sensitivity and increase of insulin resistance are more obvious in hypertensive patients with genotype G of the 3 genes of SM constitution than in those of PI constitution. Therefore, the difference in constitution might be one of the genetic characteristics for insulin resistance in hypertensive patients.</p>

<p><b>OBJECTIVE</b>To investigate the relationship between the polymorphism of alpha-adducin (ADD1) gene and the two phenotypes of constitution in patients with essential hypertension, the Yang-hyperactive (YH) type and phlegm-dampness (PD) type, classified by traditional Chinese medicine (TCM) approach.</p><p><b>METHODS</b>Two hundred and seven patients differentiated by TCM approach as YH type (113 cases) or PD type (94 cases) were observed, with the systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), fasting blood glucose (FBG), serum creatinine (Cr), uric acid (UA), total cholesterol (TC) and triglycerides (TG) as the criteria of observation. Gly460Trp polymorphism of the ADD1 gene was detected by MALDI-TOF mass spectrometry. Results The levels of BMI, DBP, FBG and UA, etc. in the PD group were significantly higher than those in the YH group respectively. The rate of GG, GT and TT type of ADD1 gene was 29.2%, 41.6% and 29.2% in the YH group, 28.7%, 48.9% and 22.3% in the PD group, showing no significant difference in ADD1 genotype distribution between the two groups, while there was also no difference in the hypertension phenotype distribution among different genotypes (both P > 0.05). For the patients with TT genotype, there were significant differences between the YH group and the PD group in BMI (24.11 +/- 3.04 kg/m2 vs 26.20 +/- 2.30 kg/m2), DBP (96.79 +/- 4.05 mmHg vs 99.56 +/- 3.90 mmHg), FBG (5.01 +/- 0.53 mmol/L vs 5.51 +/- 1.07 mmol/L) and UA level (302.22 +/- 71.95 micromol/L vs 358.25 +/- 88.75 micromol/L, all P < 0.05).</p><p><b>CONCLUSION</b>There was no relation between ADD1 gene polymorphism and the TCM genotype of constitution in patients with essential hypertension. However, it is likely that for hypertension patients with TT genotype, those of PD type are more susceptible to cardiovascular disease and have worse prognosis than those of YH type.</p>
