AIM: To investigate the effects of different phacoemulsification incision for tear film stability in cataract patients.
METHODS: From January 2014 to September 2015, 108 patients (144 eyes) who underwent cataract surgery were divided into two groups: group A with clear corneal incision ( 52 cases with 74 eyes), group B with scleral tunnel incision (56 cases with 70 eye). Two groups of patients were taken the same incision width. Symptoms of dry eye and tear film break - up time ( BUT) were observed 1d before and 1d, 1, 3wk, 1 and 3mo postoperatively.
RESULTS:After performing cataract phacoemulsification 1d, 1wk, symptoms score of dry eye of group A was less than that of group B, the difference was statistically significant (t = -6. 199, -2. 871, P<0. 01), while at other times after operation there were no significant differences ( t = - 1. 639, - 0. 829, - 0. 301, P >0. 05); at postoperative 1d, 1 and 3wk, BUT of group B was better than those of group A, there were a statistically significant differences ( t = - 3. 718, -2. 342,-2. 506, P<0. 05), there were no significant differences at other the time after operation (t= -0. 882,1. 225, P>0. 05).CONCLUSION: The difference on effect of two different incision on the tear film stability only last a short time, which disappeared at 1mo after operation. The clear corneal incision has stronger impacts on tear film stability than scleral tunnel incision, while with a lower score on symptoms of dry eye.

Since the first reported case of swine influenza A in Mexico, a total of 15 510 cases have been confirmed in 53 countries by May 29, 2009. On April 29, 2009, the World Health Organization (WHO) raised its pandemic alert from grade 4 to grade 5. The virus is described as a new subtype of A/H1N1 and is not detected in pigs or humans previously. The virus is sensitive to oseltamivir and zanamivir, but resistant to amantadine and rimantadine. The genetics of the virus are so novel that humans are unlikely to have much immunity to it. The virus can transmit from human to human; therefore it is necessary to enforce quarantine measure for close contactors because the virus transmits during latency. Precaution methods like covering noses and mouths with a tissue when coughing or sneezing can reduce the transmission opportunity. Hands should be washed frequently with soap, especially after coughing or sneezing. Public places with ventilation conditions, personal health behavior and health condition are critical for the prevention and control of this epidemic.

Objective: To analyze evolutionary characteristics of the matrix protein (M) and nucleoprotein (NP) genes of influenza virus A/H1N1 in 2009 pandemic. Methods: The M and NP genes of A/H1N1 viruses were downloaded from NCBI database. MEGA4.0 software and NJ method were used for sequence alignment, protein sequence alignment, and the phylogenetic tree construction. Meanwhile, Epi Info software was used to analyze the linear trend of evolutionary distance of the M and NP genes of human H1N1 strains isolated during 1918 to 2009. Results: The M and NP gene sequences were similar among the novel A/H1N1 viruses, but different from those of the previous influenza H1N1 viruses. Using reference sequences of human H1N1 strains isolated during 1918 to 2008, we found that changes in evolutionary distances of the M genes between novel A/H1N1 strains and each of the reference A/H1N1 strains increased with increasing year intervals (Ptrend = 0.001). Compared with the amino acid sequence of M2 protein of reference human A/H1N1 virus strains isolated during 1918 to 2008, the novel A/H1N1 viruses had the amino acid substitutions at 6 sites: 11, 43, 54, 57, 77, and 78. Compared with swine and avian A/H1N1, the novel A/H1N1 virus only had the amino acid substitutions at 43 and 77. Conclusion: The NP gene of novel A/H1N1 virus, which is routinely considered as a conserved sequence, is different from those of the previously isolated human H1N1 influenza viruses; the related mechanisms and consequences on viral activity remain to be elucidated. The substitution to threonine at 11 and 43 amino acids of M2 protein might contribute to amantadine resistance of the novel H1N1 virus pandemic in 2009.
