International Eye Science 2016;16(6):1063-1066
? Intraoperative floppy iris syndrome is a particular symptom in phacoemulsification, and it is often occurred in patients with the history of using alpha-1 adrenergic antagonist before cataract surgery. Although the pupil be fully mydriatic before the operation, the progressive constricting of the pupil, the relaxing of iris even the iridoptosis and the unstable anterior chamber still can be found during the phacoemulsification. If treated inappropriately, severe complications and terrible outcomes may happen, which would influenced the surgery effectives. This paper reviewed the epidemiological characteristics, pathogenesis, risk factors, clinical manifestations, complications, and coping strategies of the intraoperative floppy iris syndrome.

Clinical characteristics were analyzed in a child with very long chain acyl-CoA dehydrogenase deficiency( VLCADD) . The gene analysis was performed in 20 exon all coding regions and 10 bp shear zone in the very long chain acyl-CoA dehydrogenase( VLCAD) gene of the case and his family members by direct sequencing of PCR-DNA from peripheral blood. The results showed that the patient presented with acute onset, clinical manifestations of repeated vomiting, poor spirit, abnormal liver function, increased myocardial enzyme kinase. At the age of one year old, this child was diagnosed with Reye's syndrome for liver injury. Genetic testing results revealed that E14 c. 1349G>A, p. R450H heterozygous mutation in VLCAD gene was found in this case, his mother, and his younger sister, and E15 c. 1532G>A, p. R511Q heterozygous mutation was found in this case and his father. The pathogenic genes of the case are from his mother and the younger sister is a carrier.

The famous veteran doctors of traditional Chinese medicine ( TCM ) are models to combine TCM the-ories , previous practitioners' clinical experiences with current medical practice for the difficult to solve clinical problems . The selection of appropriate inheritance study method is especially important in the learning of fa-mous veteran doctors of TCM . This article discussed the inheritance method of academic experiences of famous veteran doctor of TCM professor Huang Yongsheng from four aspects, which were the reading of classic books, clinical practice, following medical masters, and summarization of clinical cases. It was hoped that during the inheritance process , efforts can be made to academic characteristics of TCM itself in accordance with its own law in order to create more and better clinical experience inheritance method.

The overall concept is the core theory of traditional Chinese medicine ( TCM ) diagnosis and treat-ment system. During the process of building TCM effect evaluation on coronary heart disease (CHD), with the defined connotation and extension of heart diseases , except the consideration on its clinical symptoms , TCM four diagnosis and various current modern cardiovascular disease diagnostic methods should be organically com-bined according to the original macro basis . The micro quantitative evaluation is given on therapeutic effect of disease treatment in order to construct the complete TCM effect evaluation system.

BACKGROUND:With the improvement of hemodialysis technology, the long-term survival rate of maintenance hemodialysis patients has been increased continual y. Nowadays, how to improve the quality of life in maintenance hemodialysis patients has been aroused widespread concern, and gradual y become the reliable indicator for comprehensive evaluation of the effect of hemodialysis. OBJECTIVE: To evaluate the effect of individualized intervention and col ective intervention on quality of life in maintenance hemodialysis patients. METHODS:Eighty maintenance hemodialysis patients, who had accepted more than 3 months of dialysis, were randomly divided into two groups (40 cases in the experimental group and 40 patients in the control group). Al the patients in the control group received 6 weeks of individualized intervention according to the pre-established schedule based on the hemodialysis routine care. Patients in the experimental group also have a period of six weeks of col ective intervention according to the pre-established weekly schedule based on the hemodialysis routine care. The quality of life of the patients was evaluated with MOS 36-item short form health survey and kidney disease quality of life short form before and after intervention. RESULTS AND CONCLUSION:After the intervention, both of the experimental group and the control group achieved significantly greater improvement than before in MOS 36-item short form health survey and kidney disease quality of life short form (P<0.01). The physical impact, overal health, emotional state, emotional impact, social function and energy of MOS 36-item short form health survey in the patients of the experimental group were higher than those of the control group after intervention (P<0.01);and the social quality, sleep, social support and patient satisfaction of kidney disease quality of life short form in the experimental group were higher than those in the control group (P<0.01). The results show that both individualized intervention and the col ective intervention based on the individualized intervention are effective in improving quality of life in maintenance hemodialysis patients and the col ective intervention can better improve the quality of life from physical, psychological and social aspects.

With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.
