Comparative analysis of characteristic of species and esterase-isoenzyme of isolates of Polyporus umbel-latus from different regions were processed. The results indicated that isolates of Jizhaoling ( Z) and Zhushiling (ZJ) have significant differences in characteristic, and enzymatic band types of the two species also have significant differences. The homology at genetics between the two isolates is 0% , and consanguinity between the two i-solates is the farthest.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

OBJECTIVETo investigate the effects of ginsenoside Rh2 (GS-Rh2) on growth inhibition and cell cycle of Eca-109 esophageal carcinoma cell line in culture.

METHODThe effects of GS-Rh2 on cell growth inhibition was detected by MTT assay. Cell cycle was analyzed by flow cytometry (FCM). Cell morphology was observed by a light microscope after HE staining. The protein expression of cell cycle components (cyclinE, CDK2, p21WAF1) were examined by immunocytochemistry and Western blot. The mRNA expression were examined by semiquantitative RT-PCR.

RESULTGS-Rh2 inhibited the proliferation of Eca-109 cells in dose and time-dependent manners. The inhibition rate was about 50% after 1-day treatment with 20 microg x mL(-1) GS-Rh2 x 20 microg x mL(-1) GS-Rh2 induced the mature differentiation and morphological reversion. With increasing dose of GS-Rh2 treatment, the cell number of G0/G1 phase was increased, whereas it decreased at S and G2/M phase. There was significant difference between 10, 20 microg x mL(-1) GS-Rh2 groups and the corresponding group without GS-Rh2 treatement. After treating cells by 20 microg x mL(-1) GS-Rh2 for 1, 2, 3 days individually, the protein and mRNA expression of both cyclinE and CDK2 reduced, while the expression of p21WAF1 enhanced gradually.

CONCLUSIONGS-Rh2 could arrest Eca-109 cells at G0/G1 phase and induce cell differentiation tending to normal. Furthermore, GS-Rh2 had an effect on expression of cell cycle components (cyclinE, CDK2 and p21WAF1) to inhibit Eca-109 cell proliferation.

Objective To observe the effect of different doses of atorvastatin combined with probucol on contrast induced acute kidney injury (CIAKI) and serum uric acid in elderly patients.Methods Totally 121 cases admitted for coronary angioplasty were randomly divided into three groups.In standard combining treatment group (n＝35),atorvastatin 20 mg qn and probucol 0.25 g,tid were given with no loading dose intake before angioplasty.In intensively combined treatment group (n＝41),atorvastatin 40mg qn and probucol 0.25 g,tid were given with a loading dose of atorvastatin 40 mg and probucol 0.5 g at 2 hours before angioplasty.In intensive atorvastatin therapy group(n＝45),atorvastatin 40 mg qn were given,with a loading dose of atorvastatin 40 mg 2 hours before angioplasty.All patients were then evaluated 24 hours before and after angioplasty procedure,and their blood urea nitrogen (BUN),serum creatinine (Scr),serum uric acid (SUA),estimated glomerular filtration rate (eGFR) by modified diet in renal disease study (MDRD) method were tested.The serum and urine at 24 hours before and after operation were collected.Neutrophil gelatinase associated lipocalin (NGAL) were determinated by enzyme linked immunosorbnent assay (ELISA) method.Results After operation,eGFR was decreased in standard combining treatment group [(76.2±14.3) ml· min-1 · 1.73 m-2 vs.(71.9±17.9) ml· min-1 · 1.73 m-2,P＜0.05],while Scr,eGFR and uNGAL showed no changes in intensively combining treatment group and intensive atorvastatin therapy group (P＞0.05) ; BUN in the two groups was decreased [(5.6± 1.4)mmol/L vs.(4.7±0.9) mmol/L,(5.3±1.2) mmol/L vs.(4.8±1.2) mmol/L,P＜0.01,P＜0.05].SUA was reduced in intensively combining treatment group (P ＜ 0.05).uNGAL was increased in standard combining treatment group (P ＜ 0.05).Conclusions For elderly patients,intensive atorvastatin therapy and combining intensive treatment can both improve CIAKI.Only combination and intensive treatment benefit for decrease of uric acid.

Objective To investigate the application of fetuses with talipes equinovarus (TE) using chromosomal microarray analysis (CMA) technology. Methods From May 2012 to June 2015, 54 fetuses were found with TE and with or without other structural anomalies by prenatal ultrasound. Karyotyping was taking for them all, and the fetuses with normal karyotypes took another CMA test. The data were analyzed with CHAS software. Finally all the cases were followed up to know about their pregnancy outcomes. Results One of the 54 cases was detected with abnormal karyotype which was trisomy 18 (2%, 1/54). CMA was undertaken to the remaining fetuses, they were divided into 2 groups, including isolated TE group (n=38) and complex TE group (n=15). The detection rate of clinical significant copy number variations (CNV) by CMA was 11% (6/53), while isolated and complex TE group were 5% (2/38) and 4/15, respectively (P=0.047). Of the 53 cases, 51 cases were successfully followed up. Eleven cases were found without TE after birth, and the false positive rate (FPR) of TE was 22%(11/51). Conclusions Whole-genome high-resolution CMA increased the detection rate by 11% in fetuses with TE. With the FPR and the detection rate of the clinical significant CNV of 2 groups, whole-genome CMA could be recommended to the fetuses with complex TE group but normal karyotypes. A series of ultrasonic tests should be suggested to the isolate TE group, while with the abnormal ultrasound, fetuses would be suggested to have CMA test for decreasing the rates of invasive prenatal diagnosis and FPR.

Objective To investigate the clinical characteristics, diagnosis and treatment of acute mesenteric venous thrombosis(MVT) in the elderly. Methods The clinical features, diagnosis, treatments and prognosis of 10 aged cases with acute MVT were retrospectively analyzed. Results The chief complaints of the 10 cases were different degrees of abdominal pain, which not paralleled with abdominal signs. The accompanying symptoms were nausea, vomiting and bloody stools and so on. All of these patients were misdiagnosised as pancreatitis, appendicitis or intestinal obstruction and so on. diagnosis of two cases was confirmed by ultrasound, 8 by CT. At the same time, 2 cases underwent angiography examination. Of the 8 cases who underwent operation, 5 cases were cured, 3 cases died (1 died of toxic shock and 2 died of multiple organ failure ). Two cases underwent conservative intervention thrombolysis. Conclusions It is essential to improve the knowledge of acute MVT,especially its intricate clinical characteristics, high rates of misdiagnosis and mortality. Early proper diagnosis is crucial. The main treatment is operation and conservative intervention thrombolysis can be performed in the patients whose bowel has not necrosed yet.
