· Application of capsular tension ring ( CTR ) in phacoemulsification has become a common method to increase the stability of the capsular bag. CTR can effectively reduce the posterior capsular opacification ( PCO) , prevent intraocular lens ( lOL ) decentration and tilt, not cause lOL degree deviation and aberration increase.ln this review, we summarized the development overview of CTR in phacoemulsification.

Objective To evaluate the efficacy of itraconazole oral solution for prevention of invasive fungal infection ( IFI ) in neutropenic patients with acute leukemia after chemotherapy.Methods Clinical data of 136 neutropenic patients with acute leukemia after chemotherapy at the Department of Hematology,Nanfang Hospital from January 2008 to December 2010 were retrospectively analyzed.Patients were divided into itraconazole group ( n =67 ) and control group ( n =69).There were 36 patients with acute nonlymphocytic leukemia ( ANLL),31 with acute lymphoblastic leukemia (ALL) in itraconazole group;while in control group,there were 30 patients with ANLL,38 with ALL and 1 with biphenotypic acute leukaemia (BAL).Patients in itraconazole group received intraconazole after chemotherapy until the neutrophil count was increased to 0.5 × 109/L or the body temperature returned to normal and without any imaging evidence of IFI.The incidence of IFI and clinical features were compared between the groups using SPSS 13.0 software.Pearson x2 test was used for nominal variables,for measurement data,t (normal distribution) or Mann-Whitney U (skewed distribution) test were used.Results There were 12 cases ( 17.9％ ) suffering from IFI in itraconazole group and 32 cases (46.4％) in the control group (x2 =12.59,P ＜ 0.01 ).For ANLL patients,the incidence of IFI in itraconazole group was significantly lower than that in control group ( 16.7％ vs.56.7％,x2 =11.53,P ＜0.01 ).In itraconazole group,the incidence of IFI in female patients was significantly lower than that in male patients ( 8.6％ vs.28.1％,x2 =4.35,P ＜0.05 ).And for the female patients,the incidence of IFI in itraconazole group was significantly lower than thatin the control group (8.6％ vs.44.7％,x2 =11.98,P＜0.01).Conclusion Itranconzole oral solution can effectively prevent IFI in neutropenic patients with acute leukemia after chemotherapy,especially for the female patients with ANLL.

Objective To observe the clinical changes in resin and porcelain veneer in restoring dental fluorosis in order to provide a basis for the repair of dental fluorosis. Methods Fifty six severe dental fluorosis patients were divided into porcelain and resin teeth group in the department of Prosthetics, school of Stomatology, Harbin Medical University during 2005 to 2008. All 162 teeth of 25 patients in porcelain group were veneered with porcelain. 201 teeth of 31 patients in resin group were repaired with resin. To evaluat the clinic effect, the veneer surface color was detected by the Easyshade computer-aided colorimeter when the repair was completed and 18 months afterward. The edge of veneer adaptation, retention, secondary caries and abutment were examined after 18 months, and classified by color, shape, function and feeling. Results The color difference between the porcelain and resin teeth group was 0.27±0.20 and 0.21±0.15 when it was completed, and it was 0.28±0.21 and 0.77± 0.68 respectively after 18 months. The color difference value of the porcelain teeth group was lower when it was completed than 18 months later(t=-13.55, P<0.01). The color difference value of the resin teeth group was lower than the porcelain teeth group after 18 months(t=-12.60, P<0.01). The percentage of level A of veneer adaptation in the porcelain group[100%(162/162)] was higher than the resin group[91.04% (183/201), χ2=15.26, P< 0.01) after 18 months. The clinical effect was divided into three degrees of excellent, moderate or failed, into which the number of the teeth catergorized was 158, 4 and 0 in porcelain group, 148, 56 and 4 in resin group respectively. The clinical effect of the porcelain group was superior to the resin group(χ2=44.24, P<0.01). Conclusions The surface color of porcelain veneer last 16nger than the resin veneer, the adaptation and clinical effect is also superior to the resin veneer. But the long-term efficacy of two methods needs further study, especially of the resin veneer.

Objective To study the clinical significance and changes of serum cardiac troponin I (CTnI) levels in children's viral encephalitis merged with myocarditis or myocardium injury.Methods CTnI and myocardium zymogram levels were detected in 40 children with viral encephalitis and other 40 children as the controls by means of ELISA.Results CTnI and myocardium zymogram levels in viral encephalitis were significantly higher than those in controls(P

OBJECTIVE: To study the percentages of polymorphonuclear leukocytes (PMN), mononuclear cells (MNC) and fibroblastic cells (FBC) in different post-traumatic intervals after skeletal muscle mechanical injury in rats. METHODS: The rat model of skeletal muscle mechanical injury was established. The rats were divided into injured groups (6 h, 12 h, 1 d, 3 d, 7 d, 10 d and 14 d after injury) and control group. The percentages of PMN, MNC and FBC in different post-traumatic intervals after skeletal muscle mechanical injury were assessed with HE staining and image analysis. RESULTS: At post-injury 6-12h, the percentages of PMN and MNC infiltration appeared in injured sites and that of PMN reached peak. At 1 d, the percentage of MNC infiltration appeared and reached peak, while that of PMN decreased. At 3-7 d, the percentage of FBC gradually increased, while that of PMN and MNC decreased. At 10-14d, the percentage of FBC reached peak. CONCLUSION The percentages of PMN, MNC and FBC in injured zones showed time-dependent changes, which might be used as reference index for determination of age of skeletal muscle injury.

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.
