Cervical cancer poses a major threat to public health worldwide, early diagnosis of cervical cancer can improve the survival rate of patients. The detection rate of the existing cervical cancer screening methods is not very stable, and there is no reliable non-invasive index to predict the recurrence, metastasis and prognosis of cervical cancer. We searched literaruture for cervical cancer-related diagnostic and prognostic indicators and included 20 related literature, confirming that liquid biopsy is expected to replace and supplement the existing methods of screening and testing. Circulating nucleotides are an important part of liquid bioassays, including circulating cell-free DNA (cfDNA) and circulating cell-free RNA (cfRNA), among which cfRNA is a potentially rich source of tumor biomarkers, especially in the early diagnosis of cervical cancer. It has unique specificity and great potential value in the early diagnosis.

Objective To investigate the effect of focal cerebral ischemic preconditioning (IPC) on brain edema and the expression of nuclear factor-?B( NF-?B) and its target gene MMP-9. Methods Forty-five SD rats were divided into 3 groups in which control group received sham surgery only, and the other two groups received 2 hours of middle cerebral artery occlusion (MCAO) followed by 22 hours of reperfusion with or without 10 minutes of IPC 3 days before. Brain water content, expression of NF-?B and MMP-9 mRNA were evaluated in each group by wet-dry weight method, immunohistochemistry staining and RT-PCR. Results Compared with the SS group, there was a lower NF-?B immunoreactivity and MMP-9 mRNA level (16 098.2?1 265.3 vs 23 565.8?1 978.4,50.7% vs 84.1%, P

Objective:To determine the relationship between injury risk and alcohol drinking. Methods:Totally 531 patients (age≥18 years) who were treated for the ifrst time and came to the emergency room within 6 h atfer the injury were included. hTe American National Institute of Health questionnaire was used to investigate the trauma type, intentional injury, drinking before the injury, drinking volume, and drinking history in the past years and so on. hTe case-crossover method was used to analyze the data and relationship between alcohol drinking and injury.Results:Compared with the non-drinkers, subjects who drank alcohol 6 h before the injury had a higher risk of intentional injury (OR=2.79, 95%CI: 1.61–4.84). Male, drunken, patients with positive alcohol test results were more likely to suffer from intentional injury. Compared with the non-drinkers, victims who drank alcohol 6 h before injury had a higher risk of injury in traffc accidents (OR=2.41, 95%CI: 1.29–4.51). Compared with the non-drinkers, subjects who drank alcohol 6 h before injury had a higher risk of injury (OR=11.86, 95%CI: 5.48–25.65). Subjects who drank more than 6 standard drinks of alcohol 6 h before injury had much higher risks than non-drinkers (OR=24.52, 95%CI: 5.84–102.86). Conclusion:Alcohol drinking before injury is associated with increased the risk of trauma, intentional injury and injury related to traffc accidents.

With the content of gallic acid, loganin, paeoniflorin and paeonol as the indexes, to screen out dissolution determination conditions, establish the dissolution determination method for multi-index components in Liuwei Dihuang concentrated pills, calculate and map the accumulative dissolution curve, and then compare the dissolution of products from different pharmaceutical factories through the similarity factor (f2). According to the results, the optimum dissolution determination conditions were the paddle method, with 250 mL 0.1 mol x L(-1) hydrochloric acid as the dissolution medium, and a rotation rate of 100 r x min(-1). The similarity factor values (f2) of the dissolution curves of the four main components of Liuwei Dihuang concentrated pills from different pharmaceutical factories were mostly less than 50. This demonstrated a significant difference in the dissolution of Liuwei Dihuang concentrated pills from different pharmaceutical factories, and provided scientific basis for improving the equality evaluation of Liuwei Dihuang concentrated pills.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) on plasma visceral adipose tissue-derived serine protease inhibitor ( vaspin ) levels in patients with recentonset type 2 diabetes mellitus, and to study the association between insulin sensitivity and vaspin levels.Methods Thirty patients with recent-onset type 2 diabetes mellitus were treated with CSII for 2 weeks.Euglycemic-hyperinsulinemic clamps (EHC) were performed to evaluate the insulin sensitivity in type 2 diabetes group. Plasma vaspin levels were measured by an ELISA kit. The association between plasma vaspin levels and metabolic parameters were analyzed. Results Fasting plasma vaspin levels were higher in type 2 diabetes than in impaired glucose regulation and normal glucose tolerance groups [( 1.83±0.55 vs 0. 43±0.21 and 0.56±0.26) ng/ml,P＜0.05]. With CSII,vaspin levels [( 1.19 ±0.57 vs 1.83 ±0.55 ) ng/ml, P＜0.05] and homeostasis model assessment for insulin resistance [HOMA-IR ,2.30 ( 1.09-7.2 ) vs 4.28 ( 1.7-6.47 ), P＜0.05] were significantly decreased,accompanied with an increase in glucose metabolic rate [(5. 10±0.51 vs 2.99±0.42 )mg·kg-1·min-1 ,P＜0.05] in type 2 diabetes group. Changes in circulating vaspin concentrations were correlated positively with changes in HOMA-IR. Conclusion In type 2 diabetic patients,elevated plasma vaspin levels are significantly decreased after CSII treatment. Vaspin may play a role in improving insulin sensitivity of diabetic humans.

Objective Via targeted inhibition of oncogene Bmi-1 expression by RNAi interfering technology in vitro, to observe its effect on the proliferation and cell cycle of gallbladder cancer cells. Methods Four miRNABmi-1 recombinant plasmids were constructed according to different Bmi-1 sites. RT-PCR and Western blot were used to mRNA and protein expression of Bmi-1 in gallbladder cancer cells were measured by RT-PCR and Western blot. mRNA and protein expression of Bmi-1 in gallbladder cancer cells. The most effective interfering plasmids in the miRNABmi-1 groups were transfected into GBC-SD cells. Cell proliferation and cell cycle were analyzed 48 h after transfection by BrdU and flow cytometry. Results Bmi-1mRNA expression in miRNAbmi1-1,-3 and-4 was significantly lower than the control group (P<0.05);and Bmi-1 protein expression in miRNAbmi1-2,-3 and-4 was significantly lower than the control group (P<0.05). The recombinant plasmid in miRNAbmi1-4, with the strongest inhibitive effect of Bmi-1mRNA and protein expression, was transfected into GBC-SD cells,then the cell proliferation rate (46.63 ± 5.31) was significantly lower in mRNABmi1-4 group than the control groups (P<0.05);G0/G1 phase cells increased (72.20 ± 1.71) and G2/M and S phase cells decreased (18.30 ± 7.21, 9.50 ± 6.01) in miRNABmi1-4 group. Both were significantly different from the control groups (P<0.05). Conclusions Targeting and silencing Bmi-1 expression can effectively inhibit the proliferation of GBC-SD cells and restrain the cell cycle atin G0/G1 phase. Bmi-1 gene may be a novel target for geneic therapy of gallbladder carcinoma.
