AlM:To explore treatment efficacy of the lower eyelid twitch muscle transposition surgery in senile entropion.METHODS:Fifty cases (86 eyes) of senile lower eyelid entropion patients underwent lower eyelid twitch muscle transposition correction surgery as the experimental group, and the other 42 cases (68 eyes) of senile lower eyelid entropion patients received orbicularis muscle shortening correction as controls group. The correction rate, double eyelid symmetry and overcorrection rate of patients were observed one week after surgery. The patients were followed up for 6~12mo to be observed the long-term recurrence rate, double eyelid symmetry and overcorrection rate.RESULTS: One week after operation, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05); After followed up for 6 ~12mo, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05). CONCLUSlON: Folding and orbicularis muscle shortening treatment of senile entropion was compared with the lower eyelid twitch muscle transposition surgery treatment of senile entropion, We can find that clinical results in double eyelid surgery symmetry and overcorrection rate are of obvious advantage.

OBJECTIVETo assess the value of fluorescence in situ hybridization (FISH) in the diagnosis of bladder cancer.
METHODSUrine samples from 100 patients suspected of having bladder cancer were collected before cystoscopy for immediate urine cytology and FISH analysis. The criteria for FISH abnormality were determined by evaluating the urine specimens from 20 subjects without urogenital neoplasm.
RESULTSThe overall sensitivity of cytology and FISH was 43.2% and 82.4%, and their specificity was 92.3% and 88.5%, with diagnostic concordance rate of 56.0% and 84.0%, respectively. The differences between FISH and cytology showed statistical significance in the sensitivity, diagnostic concordance rate, non-muscle-invasive cancer and primary cancer.
CONCLUSIONThe sensitivity and efficiency of FISH in the detection of bladder cancer are superior to those of cytology, especially for prophase cancer.

The growth inhibitory effects of D-glucosamine hydrochloride (GlcNH(2).HCl), D-glucosamine (GlcNH(2)) and N-acetyl glucosamine (NAG) on human hepatoma SMMC-7721 cells in vitro were investigated. The results showed that GlcNH(2).HCl and GlcNH(2) resulted in a concentration-dependent reduction in hepatoma cell growth as measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. This effect was accompanied by a marked increase in the proportion of S cells as analyzed by flow cytometry. In addition, human hepatoma SMMC-7721 cells treated with GlcNH(2).HCl resulted in the induction of apoptosis as assayed qualitatively by agarose gel electrophoresis. NAG could not inhibit the proliferation of SMMC-7721 cells. GlcNH(2).HCl exhibited antitumor activity against Sarcoma 180 in Kunming mice at dosage of 125-500 mg/kg, dose of 250 mg/kg being the best. GlcNH(2).HCl at dose of 250 mg/kg could enhance significantly the thymus index, and spleen index and could promote T lymphocyte proliferation induced by ConA. The antitumor effect of GlcNH(2).HCl is probably host-mediated and cytocidal.

OBJECTIVETo investigate the effects of Shadu Cao Mixture (SDCM, traditional Chinese medicine) on immune functions of immunosuppression mice.
METHODSFifty BALB/C mice were randomly divided into blank control group, model group, SDCM low-dose, middle-dose and high-dose group. Except the blank control group, other groups were intraperitoneal injected with cyclophosphamide (40 mg/kg) to establish immunosuppression mice model. The blank control group and model group received gavage administration with nonnal saline, while the other groups received gavage administration with different doses of SDCM (10, 20, 40 m/kg for 15 days) respectively. The number of leukocytes and serum levels of interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in peripheral blood, spleen index, and the function of NK cells were measured.
RESULTSCompared with the model group , SDCM increased the number of leukocytes and serum concentrations of IL-2, TNF-α and IFN-γ in peripheral blood and improved the spleen index and the function of NK cells significantly (P < 0.05-0.01).
CONCLUSIONSDCM could remarkably enhance the immune functions of immunosuppression mice induced by cyclophosphamide.

OBJECTIVETo identify a rare α-thalassemia gene mutation in a family from south China and perform a pedigree analysis and genetic diagnosis of hemoglobin H (HbH) disease caused by this mutation.
METHODSPeripheral blood samples were collected from the family members for analysis of the hematological phenotype and routine test of thalassemia genes. DNA sequencing was carried out for samples that showed genotype and phenotype inconsistency.
RESULTSA rare α-thalassemia *92A>G gene mutation was detected within this family. The proband and his sister were confirmed to have non-deletional HbH disease with α--/αα genotype. The proband's brother was confirmed to have an α-thalassemia trait with the genotype of -α/αα. The proband's father was identified as an α-thalassemia silent carrier with the genotype of αα/αα.
CONCLUSIONA rare α-thalassemia *92A>G gene mutation was identified for first time in south China. The description of the basic phenotypic characteristics of α-thalassemia trait and silent carrier caused by this mutation enriches the α-thalassemia gene mutation spectrum in Chinese population and helps in population screening, clinical molecular diagnosis and genetic counseling.

OBJECTIVETo report our data of patients with clinical stage T(1-3)N(1-2)M(0) renal cell carcinoma (RCC) and explore the biological behavior of this malignancy.
METHODSA total of 531 patients with no distant metastatic RCC underwent open radical nephrectomy at our institution between 1988 and 2008, among whom 42 patients with histological nodal metastases had successful surgical tumor resection. The clinical data and outcomes of the 42 patients were analyzed.
RESULTSOf those 42 patients, 19.0% had T1, 21.4% had T2, and 59.5% had T3 stage tumors; 42.9% had N1 and 57.1% had N2 stage tumors. Tumor recurred in 30 (71.4%) patients after the surgery, and death occurred in 26 (61.9%) cases at the last follow-up; among the recurrent cases, 83.3% (25/30) had multiple metastases at the initial recurrence. The median cancer-specific survival (CSS) and disease-free survival (DFS) was 23 and 11 months in these cases, respectively. Multivariate analysis demonstrated that Fuhrman grade (P=0.005), N stage (P=0.014) and T stage (P=0.037) were the independent predictors of CSS; Eastern Cooperative Oncology Group (ECOG) performance status (PS) (P=0.002), tumor size (P=0.007), Fuhrman grade (P=0.009) and N stage (P=0.019) were the independent predictors of DFS.
CONCLUSIONPatients with T(1-3)N(1-2)M(0) RCC have poor prognosis. N stage is an independent predictor of both CSS and DFS, suggesting that extended lymph node dissection should be performed when suspicious enlarged nodal disease is found during surgery.

OBJECTIVETo investigate subtype and genetic analysis of human immunodeficiency virus type-1 (HIV-1).
METHODSDNA sequences were amplified by nested-PCR from uncultured peripheral blood mononuclear cells (PBMC) obtained from 100 HIV-1 patients from Guangdong Province. The C2 to V3 region of the envelope glycoprotein gp120 of HIV-1 was sequenced directly. The analysis of the gene-based phylogenetic tree and variation of amino acid were carried out by using Wisconsin software package or genetics computer group (GCG).
RESULTSDNA fragments were amplified from 75 PBMC samples by using nested polymerase chain reaction (PCR). Sequence analysis showed that there were 3 HIV-1 subtypes or circulating recombinant forms (CRF): CRF01-AE (n = 44), CRF-BC (n = 27) and B' (n = 4).
CONCLUSIONSThree HIV-1 subtypes or circulating recombinant forms: CRF01-AE, CRF-BC and B' might be circulating in Guangdong Province. Findings from this study suggested that several subtypes might exist in Guangdong Province and the epidemic situation of AIDS be serious. It should be a challenge for Guangdong Province in treating patients, preventing and controlling AIDS in the future.
