AIM: To evaluate the effect of the chosen incision on corneal astigmatism after implantable collamer lens ( ICL) surgery.
METHODS:The study included 195 eyes of 102 patients, and all eyes were randomly divided into two groups: the chosen incision group ( Group A, 97 eyes) and temporal corneal incision ( Group B, 98 eyes ) . Before the operation, and 1wk, 1mo and 3mo after the operation, each patient was examined with corneal topography to observe the changes of corneal astigmatism.
RESULTS: Preoperative corneal astigmatisms were (1-26±0. 35) D in group A and (1. 28±0. 38) D in group B, thus there was no statistically significant difference ( P>0-05). One week postoperatively, the astigmatism were (0.93±0.29)D in group A and (1.32±0.33)D in group B. One month postoperatively, the astigmatism were (0. 85±0.16)D in group A and (1.27±0.18)D in group B. Three months postoperatively, the astigmatism were ( 0. 80±0-13)D in group A and (1. 25±0. 20) D in group B. The differences between the two groups were statistically significant (P<0. 01).
CONCLUSION: The chosen incision can reduce postoperative astigmatism to a certain extent after ICL surgery.

To investigate and analyze the epidemiology of serious corneal ulcer.
● METHODS: A total of 133 serious corneal ulcercases from June 2010 to December 2013 in Xiangya Hospital Affiliated to Central South University were retrospectively reviewed for risk factors, demographic characteristics and diagnosis.
●RESULTS: There were 91 male patients (68. 4%) in the 133 patients. A peak incidence age was from 41 to 60 years old (82 cases, 44. 4%). Most of patients were peasant (77 cases, 57. 9%) and the percentage of the low schooling patients was 85. 0% (113 cases). The number of patients who had been sick was 73 before hospitalization (54. 9%) in all cases. The peak incidence season was January (34. 6%). Average length of stay was 9. 84d. The number of emergency cases was 44 (33. 1%). Most of patient were not only corneal ulcer cases but the hypopyon (92 cases, 69. 2%). The figure of inpatients who received operations was 102 cases ( 76. 7%). And the most of operations was amniotic membrane transplantation (31 cases, 39. 2%). Additionally, this data was classified regard to gender differences.
● CONCLUSlON: The peasant of the middle age and elderly represents a distinct clinical group in the serious corneal ulcer in hospital. Severity, ocular trauma in agriculture and health awareness are the major predisposing factors.

OBJECTIVE To investigate the application of antibacterials in patients accepted operation in grass-roots(hospitals),so to standardize the application of antibacterials and cut down the medical cost.METHODS Full-time administrators for nosocomial infection investigated the application of antibacterials in patients who accepted(operation) in Sep 2004,and filled in the questionnaires.RESULTS In 1 383 cases of 11 hospitals the application rate of antibacterials was 98.63%;in which 86.50% were for prophylactic usage and 13.50% for therapeutic usage;(29.90%) for single antibiotics treatment and 50.15% for bigeminy,18.70% were for trigeminy.Time of(application) differentiated(6.90,7.00,6.60d) fromⅠto Ⅲ kinds of operation.Per capita cost of antibacterials was $956.50(47.60%).CONCLUSIONS High cost of antibacterials results from such factors as multiple kinds,long time and(combined) application.

AIM: To test the ability of multifocal visual evoked potential (mfVEP) in the detecting of glaucoma by comparing the mfVEP recorded from normal subjects and glaucoma patients.METHODS: The mfVEP of 32 normal eyes (n =21) and of 58 eyes (n =37) with primary glaucoma were recorded with the Vision Monitor electrophysical apparatus by the second kernel analysis and to determine the correlation of the topographic location between them.RESULTS: There were significant variability (the coefficient of variation was 43.05%) in mfVEP RMS amplitude in the normal subjects; The RMS amplitude of eyes with glaucoma were smaller than that of the normal eyes and significantly statistical difference were found in the relatively center (namely the 0° -10° ring zone) and in superior nasal quadrant (P＜0.05) while there were no significantly statistical differences of the latency time between them.CONCLUSION: The normal subjects have large individual variability of mfVEP responses. The RMS amplitude of the mfVEP of glaucomatous eyes descends, especially in center zone and superior nasal quadrant.

Through retrieval of all medical journals of CNKI and VIP from Jan. 1996 to Oct. 2012, ninety-nine articles were selected and analyzed. The result shows that reliable effect can be found in pain relieving, especially in pain of muscles and soft tissues. In mechanism research, action mechanism of Fu's subcutaneous needling (FSN) on pain relieving is expounded through theory of traditional medicine and modern medicine. Although the effect of FSN on pain relieving has been confirmed by numerous clinical trials, it is still lack of explanation on mechanism revealing. The further studies should focus on mechanism expounding, improving research methods and selecting more objective and reasonable evaluation system. Therefore, the effectiveness and scientificalness of FSN can be further enhanced.

OBJECTIVETo study the proliferation and apoptosis of tetramethylpyrazine (TMP) on leukemic U937 cells and its possible mechanism.

METHODThe inhibitory effect of TMP on the proliferation of U937 cells was detected by CCK-8 assay. The cell apoptosis and cycle distribution were examined by the flow cytometry. The mRNA expressions of bcl-2 and P27 were determined by the Real-time PCR. Western blot was carried out to detect bcl-2, caspase-3, cyclin E1, CDK2 and P27 expressions.

RESULTTMP inhibited the proliferation of U937 cells in a dose-and-time dependent manner, with IC50 value of 160 mg x L(-1) at 48 h. In addition, TMP could induce the apoptosis of U937 cells and block the cell cycle in G0/G1 phase. According to the results of Real-time PCR and Western blot, TMP could down-regulate the expression of apoptosis-related molecule bcl-2, cycle-related protein cyclin E1 and CDK2 and up-regulate caspase-3 and P27.

CONCLUSIONTMP shows the effects in inhibiting the proliferation of leukemic U937 cells and inducing the apoptosis. Its mechanism may be related to the impacts on the cell cycle distribution, down-regulation of the bcl-2 expression, which finally activates caspase-3, starts the apoptosis path and causes the cell apoptosis.

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.
