AlM:To observe the relationship between axial length and complications of phacoemulsification with intraocular lens ( lOL) implantation in high axial myopia eyes and normal axis eyes.
METHODS: A retrospective review of 843 consecutive patients ( 1 042 eyes ) of cataract extraction with phacoemulsification and lOL implantation in our hospital from February 2012 to February 2013 was performed. The patients were divided into two groups according to the axial length: 853 eyes were in normal axis group ( 21-24mm) and 189 eyes were in high axial myopia group (≥26mm). The two groups were compared regarding surgical complications, such as vitreous loss, posterior capsular rupture, nucleolus drop, and abnormal location of lOL.
RESULTS:Age was a risk factor in both groups. There was positive correlation between age and surgical complications, and between axial length and surgical complications, especially for complications with posterior capsular rupture and vitreous loss.
CONCLUSlON:As the results illustrate, in this survey, age and high axial lengthare statistically significant risk factors for incidence of complications of phacoemulsification. Anticipation of these complications and also preparation and prophylactic measures may decrease incidence of these complications.

OBJECTIVETo evaluate the short term clinical results of scaling and root planning (SRP) only, SRP combined with amoxicillin (AMX) and metronidazole (MTZ) after supragingival scaling or after SRP in the treatment of aggressive periodontitis (AgP).
METHODSA total of 45 patients with AgP were randomly divided into SRP group, SRP with AMX + MTZ after supragingival scaling group and AMX + MTZ after SRP group. Subgingival scaling and root planning were performed one week after supragingival scaling and finished within 1 month. AMX and MTZ were given for 7 days immediately after supragingival scaling or the last time of SPR. Clinical examinations including probing depth (PD), attachment level (AL) and bleeding index (BI) were performed at baseline and 8 weeks after non-surgical periodontal treatment by the same examiner.
RESULTSThere were more PD reduction and AL gain in both AMX + MTZ after supragingival scaling group and AMX + MTZ after SRP group compared with SRP group [2.5 (1.8, 3.3) mm, 2.3 (1.9, 2.7) mm vs. 1.8 (1.3, 2.1) mm, P < 0.05]; [0.9 (0.5, 1.4) mm, 0.8 (0.4, 1.3) mm vs. 0.4 (0.2, 1.0) mm, P < 0.05]. In sites PD ≥ 7 mm, PD reduction was more in AMX + MTZ after supragingival scaling group than AMX + MTZ after SRP group [4.0 (3.0, 5.0) mm vs. 4.0 (3.0, 4.0) mm, P < 0.05)].
CONCLUSIONSThe combined use of AMX and MTZ during non-surgical periodontal treatment for patients with AgP was effective in short term. In patients with most sites PD ≥ 7 mm, AMX and MTZ could be taken after supragingival scaling, but the long-term clinical effects needs further investigation.

OBJECTIVE Liver cancer is one of the most common causes of cancer related deaths worldwide, specially, in China. Hinesol, extracted from Atractylodeslance a(Thunb.) DC. has been proved that has anti-cancer effect in leukemia in vitro and in vivo.However,it has been not well under-stood in liver cancer cells.METHODS Cell proliferation,apoptosis,cell cycle and invasion were performed to investigate the anti-liver cancer effect of hinesol in SMMC-7721 and LM3 by MTT assay,flow cytometry and scratch assay.Western blot was used to research the potential mechanism.RESULTS We revealed that hinesol suppresses cell proliferation and invasion,prompts population of G1 phase,induces apop-tosis in dose-dependent manner in SMMC-7721 and LM3 cells.Western blot data showed that hinesol could inhibits the expression of cyclin-D1, Bcl-2 and Bax, and inhibited phosphorylation of MEK and ERK, down-regulated the expressions of NF-κB p65 and phosphor-p65 in nucleus. The results indicated that hinesol reduces cell proliferation via arresting cell cycle at G1 phase and induces apoptosis.Further-more,western blot showed that hinesol inhibited phosphorylation of MEK and ERK,down-regulated the expressions of NF-κB p65 and phosphor-p65 in nucleus.CONCLUSION Our results demonstrate that hinesolreduces cell proliferation via arresting cell cycle at G1 phase and induces apoptosis, it has potent anti-cancer effect against liver cancer cells via down-regulation of MEK/ERK and NF-κB pathway,and indicate that hinesol is a potential liver cancer drug for further research.
