Objective: To develop the ultra performance liquid chromatography tandem mass spectrometry ( UPLC-MS/MS ) for the determination of perfluorocarboxylic acids ( PFCAs ) in fish. Methods: The fish samples were extracted with tert-butyl methyl ether and purified by WAX columns. The WAX cartridges were rinsed with methanol and 25 mmol/L ammonium acetate, and the target compound residues were eluted with 0.5% ammonia methanol and then redissolved with 50% methanol aqueous solution after nitrogen blowing to nearly dry. Nine kinds of PFCAs were simultaneously quantified by UPLC-MS/MS with 1 mmol/L ammonium acetate-methanol solution as the mobile phase. Results: The extraction was separated well in UPLC BEH C18 column. There were good linear correlations of nine kinds of PFCAs in the range of 1.0-200.0 ng/mL, with the coefficients all more than 0.99. The limits of detection and quantification were 0.06-0.19 μg/kg and 0.19-0.62 μg/kg, respectively. The recovery rates were 70.08%-117.24% at different spiked levels ( 5.0, 25.0, 50.0 μg/kg ), and the relative standard deviations were 2.31%-19.68%. Conclusion Through optimizing the pretreatment conditions, the mobile phase of liquid chromatography and the detection conditions of mass spectrometry, the UPLC-MS/MS could meet the monitoring requirements of PFCAs in fish.

To study whether commercial traditional Chinese medicinal preparations Injection Paederiae (IP) or Injection Stauntonia (IS) has anti-nociceptive and/or anti-inflammatory effects, we used two persistent pain models (bee venom and formalin test) to evaluate the systemic effects of IP or IS on the chemical tissue injury-induced persistent spontaneous pain-related responses (PSPR), primary thermal/mechanical hyperalgesia and inflammation in conscious rats. Injection of bee venom (BV, 0.1 mg, 50 microl) into the plantar surface of one hind paw resulted in not only a 1-h monophasic PSPR such as flinching reflex in the injected paw and a subsequent period of 3-4 days primary heat and mechanical hyperalgesia, but also a marked sign of inflammation, including redness and swelling of the plantar surface in the injected paw. Intraplantar injection of formalin produced two phases of PSPR as reported previously. Systemic pre-treatment with three doses of IP (0.32, 1.6 and 9.0 ml/kg, 500%) or IS (0.32, 1.6 and 9.0 ml/kg, 250%) produced a dose-dependent suppression of the BV- or formalin-induced flinching reflex of 1 h time course as compared with the saline control group. Post-treatment with IP or IS 5 min after BV injection also produced a significant suppression of the flinching reflex in both BV test and formalin test respectively, as compared with the control group. However, neither pre- nor post-treatment with IP or IS produced any significantly suppressive effect on the BV-induced primary heat and mechanical hyperalgesia and inflammation. The analgesia produced by IP or IS was not mediated by the endogenous opioid receptors since naloxone, a non-selective opioid receptor antagonist, had no reversal effect on the IP and IS-produced analgesia in the BV-induced PSPR. Our present results suggest that IP or IS might prevent and relieve clinical persistent spontaneous pain, but without any anti-nociceptive and anti-inflammatory effects on the primary heat hyperalgesia, mechanical hyperalgesia, as well as inflammatory responses. The BV test might be a useful model of pain to evaluate and screen anti-nociceptive and anti-inflammatory effects of certain compounds of the Chinese medicinal herbs on the pathological origins of pain.

LncRNAH19 has been implicated as having both oncogenic and tumor suppression properties in cancer. LncRNAH19 transcripts also serve as a precursor for miR-675. However, it is unknown whether LncRNAH19 and miR-675 are involved in the migration and invasion of hepatocellular carcinoma (HCC) cells. The purpose of this study was to investigate the effect and mechanism of LncRNAH19 and miR-675 on migration and invasion of HCC cells. The migration and invasion of HCC cells were measured by Transwell migration and invasion assays after transfection of HCC cells with miR-675 inhibitors and LncRNAH19siRNA. The levels of LncRNAH19 and miR-675 were detected by quantitative reverse transcriptase real-time polymerase chain reaction (qRT-PCR), and the protein expression of AKT, GSK-3β and Cdc25A by Western blotting analysis. The expression levels of LncRNAH19 and miR-675 were higher in MHCC-97H cells than in L02, Huh-7 and HepG2 cells. Transwell migration assay revealed that the miR-675 inhibitor and LncRNAH19siRNA could significantly increase the migration of HCC cells (P<0.01) as compared with the control group. Transwell invasion assay demonstrated that the miR-675 inhibitor and LncRNAH19siRNA could significantly increase the invasion of HCC cells (P<0.01) as compared with the control group. Western blotting analysis showed that the expression levels of AKT and Cdc25A were significantly increased (P<0.05), and the expression level of GSK-3β was significantly decreased (P<0.05) after treatment with miR-675 inhibitors and LncRNAH19siRNA as compared with the control group. These findings suggested that inhibition of LncRNAH19 and miR-675 expression can promote migration and invasion of HCC cells via AKT/GSK-3β/Cdc25A signaling pathway.

Objective To observe the changes of serum potassium concentration in rectal cancer patients from the admission to before the operation,to provide clinical evidence for preventing serum potassium disorder during and after their operation.Methods Monitoring of the changes of serum potassium concentration of 40 cases of rectal cancer patients according to three time points including the first day of admission,before taking of cathartics and the morning before operation.They were divided into different groups according to their age(young,middle age and elderly group),gender(male and female group),diet(normal,decreased slightly and serious decline group) and course(long,middle and short course group) of disease.The serum potassium concentration was observed between each time point of each group and SPSS13.0 statistical software was used to analyze the changes above.Results The mean of all patients' serum potassium concentration was (4.09 ± 0.62) mmol/L on the first day of admission,was (3.83 ± 0.46) mmoL/L before taking of cathartics that was decreased compared to the former and there was significant difference (P ＜ 0.01),it was (3.36 ±0.40) mmol/L on the morning of operation and had significant difference with the above two groups (P ＜ 0.01).It hadn't significant difference between different gender and age groups at different time points (P ＞ 0.05) except between the young group and the elderly group in the morning of the operation (P ＜ 0.05).There were statistically significant differences between the different diet condition and different course at anytime point (P ＜ 0.01).Conclusions The rectal cancer patients were possiblely in hypokalemia before operation,the causes might be relative to the long course of disease,the decreased diet,the aged and infirm,the diet structure change after admission and taking cathartics cleaning intestinal tract.

Objective In order to provide clinical evidence of reducing postoperative complications of procedure for prolapse and hemorrhoids and observe the effects of constipation on postoperative complications of procedure for prolapse and hemorrhoids.Methods One hundred and sixty cases of hemorrhoid were divided into two groups according to whether suffering from constipation:there were eihgty cases who were suffered from constipation in the experimental group and eighty cases who were not suffered from constipation in the control group.All patients' postoperative bleeding,anal edema,stool impaction and satisfaction were observed within 30 days and these data were compared and analysed by using SPSS 13.0 software.Results In the experimental group,the postoperative bleeding incidence was 37.5 ％ (30/80),the anal edema incidence was 31.3 ％ (25/80),the stool impaction inci dence was 8.6％ (7/80),and the patients' satisfaction rate was 88.6％ (71/80).In the control group,the postoperative bleeding incidence was 18.6％ (15/80),the anal edema's incidence was 15.0％ (12/80),the stool impaction incidence was 1.3％ (1/80),and the patients' satisfaction rate was 97.5％ (78/80).All the indexes above were different statistically in the two groups (P ＜ 0.05).Conclusion constipation could increase complications and reduce the degree of satisfaction after procedure for prolapse and hemorrhoids.

A novel and sensitive HPLC-UV method has been developed for the simultaneous determination of twelve major compounds in Longdan Xiegan Pill.The chemical profile of the twelve compounds,including geniposidic acid (1),geniposide(2),gentiopicroside(3),liquiritin(4),crocin(5),baicalin(6),wogonoside(7),baicalein(8),glycyrrhizic acid (9),wogonin (10),oroxylin A ( 11 ) and aristolochic acid A (12),was acquired using high-performance liquid chromatography-diode array detector coupled with an electrospray tandem mass spectrometer (HPLC-DAD-ESI-MS).The analysis was performed on a Dikma Platisil ODS C18 column (250 mm × 4.6 mm,5 μm ) with a gradient solvent system of acetonitrile-0.1％ aqueous formic acid.The validation was carried out and the linearities ( r ＞ 0.9996),repeatability (RSD＜1.8％),intra- and inter-day precision (RSD＜1.3％),and recoveries (ranging from 96.6％ to 103.4％ ) were acceptable.The limits of detection (LOD) of these compounds ranged from 0.29 to 4.17 ng.Aristolochic acid A,which is the toxic ingredient,was not detected in all the batches of Longdan Xiegan Pill.Furthermore,hierarchical cluster analysis was used to evaluate the variation of the herbal prescription.The proposed method is simple,effective and suitable for the quality control of this traditional Chinese medicine (TCM).
