ABSTRACT
@#AIM: To evaluate the refractive errors after phacoemulsification combined with intraocular lens(IOL)implantation in previously vitrectomized eyes.<p>METHODS: Thirty-eight patients(40 eyes)with cataract who had undergone vitrectomy were divided into two groups: vitrectomy alone as group A(22 eyes), vitrectomy combined with inert gas(C<sub>3</sub>F<sub>8</sub>)tamponade as group B(18 eyes). In addition, normal eyes(20 eyes)without vitrectomy history who required cataract surgery were included as a control group C. Axial length(AL), keratometric value(K), anterior chamber depth(ACD), and white-to-white(W-W)were measured with IOL Master 500 before the surgery. The power of IOL was calculated with the online Barrett Universal Ⅱ formula. Phacoemulsification combined with IOL implantation by an iris hook assistance technique was used to treat groups A and B, group C was treated only with phacoemulsification and IOL implantation. There were no complications, such as posterior capsule rupture. The postoperative refraction was obtained three months after surgery. The prediction error(PE), absolute prediction error(AE), and median absolute error(MedAE)among the three groups were compared.<p>RESULTS: There was no significant difference among the three groups in AL, K value, and IOL power. A significantly deep ACD was noted in groups A and B compared with group C(<i>P</i><0.01). There was a significant difference in the prediction error among the three groups(<i>P</i>=0.042). Group B showed a significant hyperopic shift compared with group C. AE and MedAE among groups showed no significant difference.<p>CONCLUSION: There was no significant difference in the refractive results of patients with phacoemulsification sequential to vitrectomy alone compared with the normal control group. However, a hyperopic shift was found in patients with phacoemulsification sequential to vitrectomy with inert gas tamponade comparing with the normal eyes. Undercorrection should be avoided when selecting IOL power.
ABSTRACT
Objective To understand the periodicity of the incidence of hand, foot and mouth disease (HFMD) in representative provinces from different climatic zones in China, and to analyze the seasonality and the factors influencing the HFMD transmission rate, to provide a scientific reference for the prevention and treatment of HFMD. Methods Five climate-representative provinces including Hainan, Hunan, Shandong, Qinghai and Inner Mongolia were selected as research objects. Wavelet analysis was used to analyze the cyclic pattern of HFMD incidence. Time series susceptible infected recovered (TSIR) model was established to examine the HFMD transmission rate of the five provinces and of the entire country. The parameters in the TSIR model were estimated by markov chain monte carlo (MCMC). Linear regression model was used to analyze the effects of climate factors, school terms and the Spring Festival travel rush on the transmission rate of HFMD. Results (1) HFMD incidence in the provinces and the entire country exhibited annual or semi-annual cycles and the transmission rates in all provinces showed obvious seasonality with similar patterns. February to May was the peak period of HFMD transmission rate. (2) The transmission rate of HFMD was affected by the climate or the contact rate, depending on which factor was dominant. Conclusions The transmission rate of HFMD had obvious seasonality, which had increased significantly in February, and it was necessary to strengthen its prevention and control during the Spring Festival.
ABSTRACT
Objective To evaluate the clinical nursing pathway in the treatment of stroke patients in combination with traditional Chinese medicine and western medicine. Methods A hundred patients were randomly divided into observation group and control group, 50 cases of each, which selected in Zhoushan Hospital of Traditional Chinese Medicine from January to December in 2015. The normal nursing methods were used in the control group and the clinical nursing paths were used in the observation group. Results The average value of Barthel score of the observation group was significantly better than that of the control group (55.93±9.12 vs. 46.51±9.29, P<0.05) . The recovery efficiency of the observation group was significantly higher than that of the control group (90.00％ vs. 62.00％, P<0.05) . The score of satisfaction of nursing work in the observation group was higher than that of the control group (9.13±0.49 vs.7.08±0.72, P<0.05), and the average length of stay was shortened (43.62±3.79 vs. 65.13±3.11, P<0.05) respectively compared with the control group, and the curative effect of topsis was evaluated by topsis method, and the Ci value of the observation group (Ci=0.781) was better than that of the control group (Ci =0.219) . Conclusion The clinical nursing pathway could significantly improve stroke patients Barthel score, muscle strength and nursing job satisfaction, and overall reduce the duration of hospital stays.
ABSTRACT
Objective To explore the relationship between detective time for serum cardiac troponin I(cTnI) and their positive rate in diagnosis of viral myocarditis(VM).Methods Twenty-one cases of VM were designed as the test group.The serum cTnI were dynamically detected and compared with the normal control group.Results The serum cTnI were all negative in the normal control group,of 6 cases(28.6%) in the test group were positive when admission,of 7 cases(33.3%),8 cases(38.1%),9 cases(42.9%),13 cases(61.9%) and 4 cases(19%) were positive 6,12,18,24,48,72 h and 10 to 14 days laters respectively.There were statistic significances,compared the accumulative total positive rate of 48 h and 72 h after hospitalization with of emission and of 10 to 14 days after hospitalization,respectively.Conclusion Monitoring serum cTnI dynamically may increase the positive rate of cTnI for the suspected patients.
