?AIM:To compare the curative effect of conjoint fascial sheath( CSF) suspension and levator muscle resection for moderate or severe congenital ptosis.?METHODS: Forty - three patients ( 74 eyes ) with moderate or severe ptosis were treated by CSF suspension or levator muscle resection randomly, and followed up for 6mo. The normalization rates of the two operations were then compared by statistical method, and the complications of the two operations were analyzed.?RESULTS: The two operations appeared no significant difference on the normalization rate for moderate congenital ptosis (P>0. 05), while the normalization rate of CSF suspension on severe congenital ptosis was significantly higher than that of levator muscle resection (P<0. 05). Less complication was happened in the CSF suspension group than in the levator muscle resection group.?CONCLUSION:CSF suspension is more effective on the treatment of severe congenital ptosis than levator muscle resection, and has advantages such as less trauma, repeatable, and less complication.

OBJECTIVETo study the methylation of CpG islands in the promoter region, expression of caveolin 1 (Cav-1) gene and their clinical significance in non-small cell lung cancers (NSCLC).
METHODSImmunohistochemistry and quanta Qd600 staining were used to detect the expression of Cav-1 in tissues from benign lung lesions (n = 17) and NSCLC (n = 123). DNA was treated with sodium bisulfite and the Cav-1 promoter region was screened using methylation-specific polymerase chain reaction for the possible methylation sites.
RESULTSCav-1 protein was highly expressed in cytoplasm and cell membrane of normal bronchial epithelium, alveolar epithelium, endothelial cells, fibroblasts and smooth muscle cells. The expression rates of Cav-1 protein were 100% (17/17) in the control group and 43.1% (53/123) in the NSCLC group (P = 0.001). Amongst the NSCLC group, there was no statistically significant difference in Cav-1 protein expression in different histologic types (P = 0.552) and tumor grades (P = 0.160). On the other hand, Cav-1 protein immunoreactivity was remarkably higher in advanced tumor stage: 72.7% in stage III A + III B, compared with 9.4% in stage I A + I B and 38.3% in stage II A + II B (P = 0.001). The expression rate of Cav-1 protein in the NSCLC cases with lymph node metastasis was 53.6%, compared with 20.5% in those without nodal involvement (P = 0.001). DNA from 40 NSCLC cases with negative Cav-1 protein expression and 12 cases of peritumoral lung tissues were extracted. Methylation in the promoter region of Cav-1 gene was not detected in lung cancer or peritumoral tissues.
CONCLUSIONSHigh expression of Cav-1 protein is respected of the aggressive clinical behavior and advanced tumor stage. Loss of Cav-1 protein expression seems not correlated to the methylation status in the promoter region of Cav-1 gene.

OBJECTIVETo study the hypoglycemic effect of the extract of B. polyandra (SHG).
METHODThe diabetic mice were induced by alloxan in ICR mice. The blood glucose concentration was measured by glucose oxidase method. The serum insulin level was determined by 125I-insulin radioimmunoassay kit. The hypoglycemic effect was evaluated by the levels of both fasting and no-fasting blood glucose. The effect on serum insulin level was estimated by the values of the blood insulin and the changes of the blood glucose induced by the glucose intraperitoneal injection. The effect on the glucose absorption was investigated by the oral sucrose or starch tolerance test.
RESULTBoth of the fasting and no-fasting blood glucose levels were decreased significantly by the treatment of 20 or 30 g raw materials crude drug x kg (-1) SHG orally for 7-10 d in ICR mice or in alloxan diabetic mice. In the oral sucrose tolerance test or oral starch tolerance test, the administration of SHG reduced significantly the peak value of the blood glucose and the area under the blood glucose-time curve (AUC) in normal or alloxan diabetic mice, respectively. These effects of SHG were similar to those of acarbose, a kind of alpha-glucosidase inhibitors. In the oral glucose tolerance test in normal and alloxan diabetic mice, SHG decreased both the blood glucose peak and the AUC induced by the glucose loading. But in the intraperitoneal injection glucose tolerance test the levels of insulin in both SHG and control mice were similar, however, the changes of the blood glucose level after the glucose-loading for 30 min in SHG mice was much lower than that in control mice.
CONCLUSIONWith the treatment of SHG, the fasting and no-fasting blood glucose concentrations were decreased and the glucose tolerance improved significantly in both normal and alloxan diabetic mice, and the inhibition of a-glucosidase might be one of its major mechanisms.

OBJECTIVETo evaluate the relationship between PAR1 (Protease-Activated Receptor 1) expression and the clinicopathologic features and to investigate the prognostic value of PAR1 expression in hepatocellular carcinoma (HCC) in early stage after curative resection.
METHODSReal-time PCR was used to detect PAR1 expression in 41 pairs of tumors and matched peritumoral samples of HCC in early stage. Prognostic value of PAR1 mRNA expression was evaluated. Meanwhile, another 49 tissue paraffin slices of HCC were tested using immunohistochemistry (Envision) and the prognostic value of PAR1 expression and other clinicopathologic factors were evaluated.
RESULTSPeritumoral PAR1 mRNA expression was significantly increased in HCCs from the patients with tumor recurrence as compared with those without recurrence (P < 0.05). Peritumoral PAR1 protein expression was related to tumor differentiation (P < 0.05). Kaplan-Meier analysis showed that Peritumoral PAR1 protein expression was associated with the overall survival (OS) (P < 0.05) of HCC patients and the time to recurrence (TTR) (P < 0.05). The 1, 3 and 5 -year overall survival time and the cumulative recurrence time in the high PAR1 protein expression group were significantly lower as compared to the low PAR1 expression group in the peritumoral liver tissue.
CONCLUSIONSPeritumoral PAR1 expression is closely associated with the prognosis of early stage HCC patients after curable surgery. PAR1 may be involved in thrombin-mediated invasion process and may be used as a prognostic marker for HCC.

OBJECTIVES:
To find the appropriate method for age estimation for different ages and sexes.
METHODS:
The costal cartilage, sternum and pubic symphysis of 91 unknowns from 2000 to 2020 from the Forensic Department of the Criminal Investigation Team of Shanghai Public Security Bureau were collected. Costal cartilage, sternal and pubic symphysis inferences were used to estimate the age, and the consistency between the estimated results and the actual physiological age of the unknowns was tested. The accuracy of age estimation of different samples was compared, and the relationship between accuracy and age and sex was analyzed.
RESULTS:
Using the costal cartilage method, the inference errors of males, females and the whole population under 40 years old were (0.608±2.298) years, (0.429±1.867) years and (0.493±2.040) years, while those over 40 years old were (-1.707±3.770) years, (-3.286±4.078) years and (-2.625±4.029) years. The differences between different age groups in these three populations were statistically significant (P<0.05). Using the sternum method, the inference errors of males and females under the age of 40 were (0.921±3.019) years and (0.452±1.451) years, while those over the age of 40 were (-5.903±5.088) years and (-1.429±2.227) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the pubic symphysis method, the inference errors of males and females under 40 years old were (-0.204±1.876) years and (0.238±2.477) years, while those over 40 years old were (1.500±2.156) years and (-2.643±4.270) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the sternum method and pubic symphysis method for age estimation of over 40 years old, the difference between different sexes was statistically significant (P<0.05).
CONCLUSIONS
All three methods of age estimation are stable and effective and more accurate for people under 40 years old. For age estimation of unknowns over 40 years old, the pubic symphysis method is preferred in males and the sternum method is preferred in females.

Tripolinolate A (TLA) is recently identified as a new compound from a halophyte plant Tripolium vulgare and has been shown to have significant in vitro activity against the proliferation of colorectal cancer and glioma cells. This study was designed to further investigate the effects of TLA on the proliferation of human normal cells, and the apoptosis and cell cycle in colorectal cancer cells, and the growth of tumors in the colorectal cancer-bearing animals. The data obtained from this study demonstrated that: 1) TLA had much less cytotoxicity in the human normal cells than the colorectal cancer cells; 2) TLA remarkably induced apoptosis in the human colorectal cancer cells and blocked cell cycle at G/M phase, and 3) TLA had significant anti-colorectal cancer activity in the tumor-bearing animals.
