AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

Abstract:
Occupational epidemiology aims to explore the effect of occupational hazards on the health of workers and understand
,
their mechanisms. It plays an important role in occupational health and occupational medicine.Currently occupational
, ,
exposures in the workplace are complex and diverse and multiple factors affect workers´ health at the same time. Therefore it
is important to elucidate the pathogenesis of occupational disease caused by occupational hazards and implement early
- -
intervention. System epidemiology collects data on multi level exposure and multi omics information to conduct network analysis
-
on the relationship amongrisk factors. and to study the mechanisms of exposures and health outcomes based on multi level data.
, , , ,
Using the study design of system epidemiology occupational environmental lifestyle and social factors are combined as a
,
system to evaluate the health of workers which can better evaluate the adverse health effects caused by occupational hazards.
- , ,
The studies base on multi omics design will explore the pathogenesis of occupational diseases at the molecular cellular and
tissue levels to evaluate the impact of occupational hazards on workers´ health and to explore interventions from multiple
-
perspectives to reduce the occurrence of occupational or work related diseases.

Objective To preliminarily evaluate the value of color power doppler ultrasonography in the diagnosis of sacroiliitis in ankylosing spondylitis(AS). Methods Fifty-seven sacroiliac joints in 31 patients with active AS and 40 sacroiliac joints in 20 volunteers were detected by color power doppler ultrasonography.The color flow signs inside the sacroiliac joints were observed,and the resistance index(RI) was measured. Results In active AS,color flow signs were seen in 55 joints,and the mean RI value was 0.53?0.08 in 45 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography.In the volunteers,color flow signs were seen in 16 joints,and the mean RI value was 0.97?0.01 in 6 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography. Conclusion The abnormal flow signs at the sacroiliac joints can be detected by color power doppler ultrasonography.Low RI values provide diagnosis evidence for active AS.

The prescriptions containing pericarpium citri reticulatae that built by Professor. Yan were collected to build a database based on traditional Chinese medicine (TCM) inheritance assist system. After analyzed by data mining, such as apriori algorithm, the frequency of single medicine, the frequency of drug combination, the association rules between drugs and core drug combinations can be get from the database. Through the analysis of 1 027 prescriptions with pericarpium citri reticulatae, these prescriptions were commonly used to treat stomach aches, cough and other syndromes. The most frequency drug combinations were "Citri Reticulatae Pericarpium-Poria", "Paeoniae Radix Rubra-Citri Reticulatae Pericarpium" and so on. The drug association rules that the confidence was 1 were "Glycyrrhizae Radix ex Rhizoma --> Citri Reticulatae Pericarpium", "Paeoniae Alba Radix-Cyperi Rhizoma --> Citri Reticulatae Pericarpium", "Poria --> Citri Reticulatae Pericarpium", and so on. The drugs in the prescriptions containing pericarpium citri reticulatae that built by Professor Yan mostly had the effects of regulating the flow of Qi and invigorate blood circulation, which reflected the clearly thought when making prescriptions.

Objective To investigate the prognostic influencing factors and recovery of CD4+ T lymphocytes in elderly HIV/AIDS patients after antiviral therapy by analyzing basic data and clinical follow-up data of elderly HIV/AIDS patients. Methods The clinical data of 3 618 elderly AIDS patients aged ≥50 yeas who received antiretroviral therapy (ART) at HIV ART sites in Liuzhou City from 2005-2015 were collected. The data, including basic information, CD4+ T cell count, WHO clinical stage, infection route and follow-up, were retrospectively analyzed. Kaplan-Meier method was used to compare the differences in patient survival, multivariate Cox regression to analyze the independent influencing factors influencing the risk of death, and to compare the recovery of CD4+ T cell counts during follow-up of patients of different genders. Results During the follow-up period, the 5-year cumulative survival rate up to the observation endpoint was 0.82 (female) and 0.66 (male). Multivariate logistic regression analysis showed that the risk factors affecting the effect of antiviral treatment were age (OR=1.909, 95%CI:1.474-2.464, P<0.001), body mass index (BMI) (OR=0.744, 95%CI: 0.574-0.965, P=0.026), opportunistic infections (OI) (OR=1.223, 95%CI:1.028-1.454, P=0.023), gender (OR=0.692, 95%CI:0.503-0.952, P=0.023) and baseline CD4+ T lymphocytes count (OR=0.563, 95%CI:0.429-0.739, P<0.001). Recovery of CD4+ T lymphocyte counts showed when baseline CD4+ T lymphocyte counts were less than 200 cells/mm3, older women with HIV/AIDS had higher CD4+ T lymphocytes than men at all times of ART treatment (P<0.05). Conclusions Older women have a higher survival rate than older men after five years of antiviral therapy. Age, BMI, gender, OI and baseline CD4+T lymphocyte count may be important indicators that affect the survival of elderly HIV/AIDS patients. Older women showed better recovery of CD4+ T lymphocytes than older men during the 4-year follow-up period after ART.
