Objective To elucidate the relationship between Child-Pugh grading and the degree of hep- atic cirrhosis.Method Six patients each with hepatic cirrhosis in Child-Pugh grade A and B were selected.The livers were observed with gross examinations during operation,and the liver specimens were observed with gross ex- aminations and also checked with light and electron microscopies.Results With naked eyes,it was quite difficult to find differences in size,shape and between different Child-Pugh grades.With hght microscopy,hepatic fibrosis of Ⅰ-Ⅱ degrees was commomly seen in Child-Pugh grade A and necrosis of hepatic cells was slight,while fibrosis of Ⅲ-Ⅴ degrees was usually found in grade B and necrosis was severe.With electron microscopy the collagen fib- rils in Disse's spaces were white cloud-like in grade A,while they were band-like in grade B.Of swelling and de- generation of organellae of hepatic and Kupffer cells,they were worse in grade B than in grade A.Conclusion The parameters in Child-Pugh grading are not complex,but they can be used to evaluate the degree of lesions. There is a positive relationship between them.

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P＜0.001; LM: t = 9. 346, P＜0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

Radiomics is an emerging tumor diagnosis and auxiliary detection technique that has undergone rapid development in the past few decades.The availability of new imaging equipment and reagents, as well as the use of standardized imaging protocol, has made quantitative and standardized imaging analysis possible.Radiomics is a field of study that involves the extraction of a large number of quantitative features from areas of interest in medical images using data-characterization algorithms, and transformation of these data into first-order or high-order data.The accuracy of clinical diagnosis and prognostic value of radiomics can be further improved by analyzing the relationship between data layers.Although radiomics has many advantages and has made great progress, its standardization, reliability, and application in large data and multicenter studies will need to be further optimized.

The new generation cyclooxygenase (COX-2) inhibitor could reduce the gastrointestinal side effect of NSAID drugs, but eventually increase the cardiovascular risk, because its selective inhibition of COX-2 induces the imbalance between PGI2 and TXA2 and the reduction of vasodilatory NO. Under pathological conditions, active oxygen species (O2-*2, etc) were used to induce endo- thelial dysfunction, activate NF-κB to induce expressions of pro-inflammatory cytokines IL-1β and TNF-α, increase ET-1, TXA2 with vasoconstrictor effect, reduce PGI2 and NO with vasodilatory effect, generate further oxidative damage together with NO, and reduce the bioavailability of NO. NO-NSAIDs and NO-Coxibs drugs raised the level of NO by introducing NO-donor (ONO2). NSAIDs drugs enhanced the anti-inflammatory activity of COX-2 and reduced gastrointestinal side effects by inhibiting selectively COX-2. If antioxidant structures with active ingredients of traditional Chinese medicines were introduced to improve the antioxidant activity of NSAIDs, they could scavenge the active oxygen species to protect the normal function of vascular endothelia and enhance the bioavailability of NO, which is conducive to enhance the cardiovascular safety of cyclooxygenase (COX-2) inhibitor.

Objective To investigate the epidemic characteristics and trends of incidence and mortality of prostate cancer in cancer registration areas in Zhejiang province from 2000 to 2009.Methods Clinical data incidence and mortality of prostate cancer were collected from 6 cancer registration areas in Zhejiang province,including Hangzhou,Jiaxing,Jiashan,Haining,Shangyu and Xianju.Crude rates,standardized rate and change trend,age-specific rates and annual percent change (APC,95％ CI) of prostate cancer were checked,sorted and analyzed in Zhejiang Cancer Center.Results The prostate cancer incidence rate from 2000 to 2009 was 9.79/100 000,age-standardized incidence rates by world standard population (ASIRW) was 6.39/100 000,and the incidence cumulative risk of males aged 0-74 was 0.72％ ; while the mortality rate was 2.73/100 000,age-standardized mortality rates by world standard population was 1.74/100 000,and the mortality cumulative risk of males aged 0-74 was 0.14％.Age-specific incidence of prostate cancer remained low before 50,years old and peaked at over 85-year-old group (130.30/100 000).Age-specific mortality of prostate cancer increased after 55,and also peaked at over 85-year-old group (81.19/100 000).The annual prostate cancer incidence rate generally grew from 1.39/100 000 (2000) to 13.89/100 000 (2009),and the APC was 14.18％ (95％ CI,9.68％-18.98％).Meanwhile,the prostate cancer mortality rate also increased from 1.52/100 000 (2000) to 3.58/100 000 (2009),and the APC was 11.83％ (95％ CI,5.69％-18.33％).Conclusion Prostate cancer incidence and mortality in Zhejiang cancer registration areas increased sharply,and the prevention and treatment of prostate cancer should be strengthened.

Objective To investigate the value of MRI combined with serum CA125 test in the diagnose of ovarian tumor.Methods To investigate the MRI and serum CA125 level of healthy control group (40 cases),benign tumor group (52 cases),and the malignant tumor group (43 cases).Results Of 95 patients with ovarian masses,CA125 was detected in the malignant patients with the sensitivity of 79.3 ％,specificity of 72.6 ％ and accuracy of 75.1％.MRI was 73.8 ％,81.2 ％,and 82.6 ％ respectively.Combined with CA125 and MRI was 69.4 ％,97.3 ％,and 88.6 ％.Youden' s index of combined detection was significantly higher than single detection (MRI combined with CA125 and single MRI u =1.97,P =0.012 5,and CA125 u =1.96,P =0.012 0).Conclusion MRI combined with CA125 could improve the accuracy of diagnosis ovarian neoplasm in clinic.
