The application of Toric intraocular lens (IOL) provides an opportunity for patients who want to remove cataract and correct astigmatism at the same time.In order to optimize the postoperative result and minimize the residual astigmatism, the accurate preoperative measurement and calculation of Toric IOL are crucial.To improve the accuracy, different astigmatism measurement devices with various advantages have been introduced into clinical practice one after another.Knowing the principle, advantages and disadvantages of the devices contributes to personalized selection of devices according to the patient's condition.Manual keratometer is still the gold standard tool for measuring curvature, and corneal topography is used to assess whether the corneal astigmatism is regular.Most devices can provide reliable corneal data for Toric IOL calculation, and it is recommended that at least three different devices should be used to enhance the prediction accuracy preoperatively.The posterior corneal astigmatism, which has an effect on the measurement and calculation of Toric IOL, has been attracting more attention of ophthalmologists.With high accuracy and strong applicability, Barrett Toric Calculator is preferred in Toric IOL calculation.Moreover, various Toric calculators and formulas can give stable and accurate results after modification and optimization.In this article, the effects of various corneal curvature measurement devices, posterior corneal astigmatism and Toric calculator on Toric IOL measurement and calculation were reviewed.

Geographic information system (CIS) was applied to analyse the endemic situation of schistosomiasis and the distribution of snails in Dali City. Hie data of endemic situation of schistosomiasis in Dali City from 2002 to 2008 were collected and a CIS database was set up. The endemic situation and the distribution of snails and acute schistosomiasis cases were analyzed by ArcGIS 9. 2 software. The results showed that the schistosomiasis transmission areas included 11 towns, 91 villages, and 401 nature villages. The trend surface analysis suggested that snail distribution in 2008 had a trend to accumulate in the northwest, while the population infection had a trend of gathering to the southeast. All acute schistosomiasis cases distributed in 6 towns, 23 villages, which showed significant aggregation by space-time clustering analysis, and three endemic villages in Xizhou Town in 2002 were identified as the first stratum endemic areas. It is concluded that CIS as database and graphics management tools can describe the epidemic situation intuitively, imaginably and macrosopically.

To explore the hemodynamic characteristics during burn shock stage in dogs immigrated onto high altitude, dogs scalded with 40% TBSA of Ⅲ degree burn (n=8) were randomly divided into a high altitude treatment group (H group) and a flatlands treatment group (F group) . All subjects were infused with lactated Ringefs solution at 1 postburn hour according to the Parkland formula. The changes in hemodynamic parameters, organ water content, pulmonary microvascular permeability, serum activity of PLA2 and CK-MB were determined. The results showed that under simulated high altitude condition sustained hypoxemia and acidosis as well as hypoxic damage of myocardial function were present before scalding, and sustained increase of PAP, PCWP and RVWI, even pulmonary hypertension and lung edema were found at 24 postburn hour in H group. At 48 postburn hour, the organ water content of heart, lung, etc increased more remarkably but urine output decreased more obviously in H group than those in F group. Serum activity of PLA2 and CK-MB increased gradually after burn. It is suggested that tissue edema may easily supervene with infusion according to Parkland formula under plateau condition. Hypoxic damage of organs should be corrected by increase of colloid volume resuscitation and dehydration treatment. Administration of hypertonic solution is able to correct burn shock.

Objective To explore the cancer incidence in registration areas in Shanxi Province. Methods Data of 8 cancer registration areas in 2011 were taken into account and cancer incidence in different areas with different ages was compared with that in other domestic areas. Results 8 395 new cases in Shanxi all cancer sites were reported in 2011, including 4 810 male and 3 585 female. The incidence of malignant cancer of Shanxi was 207.53/100 000, and the standardized incidence of Chinese population and world population were 125.20/100 000 and 165.72/100 000, respectively. In urban areas, the incidence of Shanxi and the standardized incidence of Chinese population were 202.49/100 000 and 112.81/100 000, respectively. In rural areas, incidence rate of Shanxi was 211.96/100 000 and the standardized incidence of Chinese population was 138.43/100 000. In Shanxi Province, the major malignant cancer sites for males involved stomach, lung, esophagus, liver and colorectum, and cancer sites for females were more on cervix, lung, breast, stomach and esophagus. Conclusions Upper gastrointestinal cancer and uterine cervix cancer are the major cancers in Shanxi registration areas. The incidence of stomach cancer and uterine cervix cancer in Shanxi Province are much higher than national average.

Objective To compare the RIFLE and AKIN diagnosis criteria for acute kidney injury ( AKI) in patients undergoing cardiac surgery. Methods Patients undergoing cardiac surgery from January 2004 to June 2007 were retrospectively evaluated. RIFLE and AKIN criteria were employed for the diagnosis and staging of AKI which occurred 7 d after cardiac surgery. The diagnosis sensitivity and precision for prediction of hospital mortality were compared between these two criteria. Results One thousand and fifty-six patients were included in this study. There was no significant difference between the prevalence of AKI after cardiac surgery diagnosed by RIFLE criteria and that diagnosed by AKIN criteria (29.55% vs 31.06%, P>0.05). There was no significant difference between the total hospital mortality and the hospital mortality of each stage of AKI diagnosed by RIFLE criteria and those diagnosed by AKIN criteria ( P > 0. 05). Logistic regression analysis suggested that the relative risk of hospital mortality for AKI was similar between patients diagnosed by AKIN criteria and those diagnosed by RIFLE criteria. The area under the ROC curve for hospital mortality was 0. 856 for RIFLE and 0.865 for AKIN in all patients (P<0.001). Conclusion Compared to RIFLE criteria, AKIN criteria do not improve the sensitivity of diagnosis and predictive ability of hospital mortality of AKI after cardiac surgery.

Objective To analyze the efficacy of early management of eomplications in patients with multi-ple traumas by applying the damage control theory. Method All total of 116 patients admitted to Wuhan Tongji Hospital between Jan 2006 and Jan 2008 were included in this retrospective study and were classified according to treatment method. Overall, 55 cases underwent damage control operations and 61 cases underwent conventional management. The groups of patients were compared in terms of parameters such as length of operation time, time to resuscitate from shock, lethal triad of death (LTD), complications and treatment outcomes after operation. Results The length of operation time was (67.43±19.52) min, resuscitation time from shock was (6.77±3.16) h and LTD was (11.54±4.10) h in the damage control group, and (163.95±55.41) min, (22.51±11.65) h and (34.55±5.63) h, respectively, in the conventional group, with significant differences between the two groups (P< 0.01). The per capita complication and mortality rates were 227.27 % and 3.64 %, respectively, in the dam-age control group and 363.93 % and 9.84%, respectively, in the conventional group (P <0.05). Couclusions Here, we demonstrated that early management of patients with multiple traumas undergoing operations by apply-ing the damage control theory significantly decreased the operation time, and decreased time to resuscitation from shock and LTD. Furthermore, this approach significantly reduced the incidence of comphcations and the mortality rate of patients with severe multiple traumas.
