Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) was adopted to analyse the relative expression of histamine H_1 receptor. And the base sequence of its PCR product was detected. RESULTS The relative mRNA expression of histamine H_1 receptor was significantly decreased in hepatic carcinoma tissue, compared with that part far from cancer and control group (P

Aim To study the biotransformation of gly-cyrrhizin in rat intestine-liver. Methods The in situ vascularly perfused rat intestine-liver model was estab-lished with a validated LC-MS/MS method for assay of the model perfusate glycyrrhizin and glycyrrhetinic acid. Results The steady state intestinal and liver ex-traction ratios in the once-through perfused rat intes-tine-liver model for glycyrrhizin were ( 4. 2 ± 0. 6 )%and (28. 0 ± 3. 0)%, respectively; the first-order ab-sorption rate constant for glycyrrhizin in the recircula-tion of perfusate to the intestine model was ( 0. 33 ± 0. 06 ) min-1;after intraduodenal administration of gly-cyrrhizin,the main active metabolite in was the perfu-sate glycyrrhetinic acid, which was also found in intes-tinal luminal fluids. Conclusions The first-pass effi-cacy of glycyrrhizin is obvious and there is only a small amount of metabolite in the intestinal mucosa cells;gly-cyrrhizin is metabolized by gut bacteria or liver cells af-ter oral administration;the in situ vascularly perfused rat intestine-liver model can be used in glycyrrhizin pharmacokinetic studies.

Objective To screen and identify the novel markers for renal cell carcinoma. Methods The renal cancer A498 cell line was used as the antigen and human normal renal cell line HK-2 was used as control for subtraction biopanning from a phage display peptide library at 37 ℃ The positive and specific binding clones were identified by cell-based ELISA and immunocytochemical staining, and the identified clones were sequenced. Thus the amino acid sequence was deduced and the peptide was synthesized. The peptide was identified by immunofluorescence. Results Through a cell-based ELISA, immunocytochemical staining, and immunofluorescence, the Phage ZT-2 and synthetic peptide ZT-2 were shown to specially bind to the A498. The affinity binding to A498 was the highest (A_(ZT-2)/A_(control) = 3. 15) among the peptides assayed. The optical density of ZT-2 in renal cancer tissue (0. 453±0. 123) was significantly higher than that in normal and inflammatory renal tissue (0. 148±0. 075)(P<0. 01). Conclusions A peptide ZT-2 which is specific binding to renal cancer cell line A498 had been selected from phage display peptide libraries. Therefore, it provides a potential tool for early diagnosis of renal cancer or targeted drug delivery in chemotherapy.

Aim To determine the effective compo-nents of Semen Ziziphi Spinosae for sedative-hypnotic and its mechanism. Methods The extraction of Se-men Ziziphi Spinosae and the rat brain homogenates were prepared. High concentrations of Diazepam com-petitively replaced the ligand compounds of Semen Ziz-iphi Spinosae combining BDZ receptor in brain tissue, and all the compounds with sedative and hypnotic effects were collected and identified by HPLC and LC-MS technique, as the compounds extracted from the brain tissue were administered with Semen Ziziphi Spi-nosae. The brain tissue was administered with Diaze-pam, and with Semen Ziziphi Spinosae and Diazepam. Results The HPLC chromatograms show that the peak time of BDZ receptor ligand compounds was 2. 71 min and 46. 87min, when compared with Diazepam. And the LC-MS chromatograms display the relative molecu-lar weight of the ligand compounds was 274. 28 m/z, 453. 34 m/z,496. 34 m/z and 608. 38 m/z respective-ly. According to the fingerprint of Semen Ziziphi Spi-nosae, these compounds may be fatty acid substances and lupine pill triterpene compounds. Conclusions On the basis of the principle of receptor ligand bind-ing, we established a way to quickly analyze and iden-tify the role of natural products in the same drug target compounds. The method not only can clearly define the effective components of natural products, but also clar-ify the mechanism of action of the compounds. The ac-tive ingredient of calm hypnosis in Semen Ziziphi Spi-nosae may be fatty acid substances Palmitic acid ( C16 H32 O2 ) and lupine pill triterpene compounds Alphitolic acid( C30 H48 O4 ) and Spinosin( C28 H32 O15 ) . They exert their sedative and hypnotic effects by combining with BDZ receptor, and the research has laid a theoretical foundation for the further study about mechanism of Se-men Ziziphi Spinosae.

Objective To investigate the clinical efficacy of laparoscopic spleen-preserving distal pancreatectomy (Kimura method and Warshaw method) for benign lesions of pancreatic body and tail.Methods The retrospective cohort study was conducted.The clinicopathological data of 39 patients with benign lesions of pancreatic body and tail who underwent laparoscopic spleen-preserving distal pancreatectomy in the Second Affiliated Hospital of Nanchang University between March 2008 and January 2018 were collected.Of 39 patients,28 undergoing Kimura method (splenic artery and vein-preserving distal pancreatectomy) were allocated into the Kimura group,and 11 undergoing Warshaw method (cutting splenic vessels and preserving short gastric vessels)due to serious adhesion between pancreatic body and tail and splenic hilum were allocated into the Warshaw group.Observation indicators:(1) operation situations;(2) postoperative situations;(3) follow-up situations.Followup using outpatient examination and telephone interview was performed to detect blood glucose level and tumor recurrence of patients up to March 2018.Measurement data with normal distribution were represented as (x)±s and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range) and comparison between groups was done using nonparametric rank-sum test.Comparisons of count data were analyzed using chi-square test or Fisher exact probability.Results (1) Operation situations:39 patients received laparoscopic spleen-preserving distal pancreatectomy,operation time and volume of intraoperative blood loss of 39 patients were respectively (194 ±58)minutes and 100 mL (range,30-800 mL).The operation time and volume of intraoperative blood loss were respectively (197±56)minutes,100 mL (range,30-800 mL) in the Kimura group and (186±63)minutes,150 mL (range,30-450 mL) in the Warshaw group,with no statistically significant difference between groups (t =0.494,Z =-0.597,P> 0.05).(2) Postoperative situations:time to anal exsufflation and duration of hospital stay were respectively (2.6±0.8)days,(9.2±7.3)days in 39 patients and (2.4±0.6)days,(7.5±4.2)days in the Kimura group and (2.8±1.3)days,(13.5±11.1)days in the Warshaw group,with no statistically significant difference between groups (t=-0.720,-1.736,P>0.05).Seven patients had postoperative complications.The incidence of complication was 2/28 in the Kimura group,1 patient with pancreatic leakage at 5 days postoperatively was cured by 15-day B ultrasound guided catheter drainage,and 1 who was diagnosed as pulmonary infection by chest CT examination at 5 days postoperatively was discharged from hospital after 8-day anti-infection and sputum-inductive treatments.The incidence of complication was 5/11 in the Warshaw group,3 patients with sustained fever at 5 and 7 days postoperatively who were diagnosed as grade 1 splenic infarction by epigastric enhanced CT examination were improved and discharged from hospital by antibiotic and low molecular weight heparin treatments,and then epigastric enhanced CT re-examination at 3 months postoperatively showed recovery of splenic perfusion;1 with pancreatic leakage at 7 days postoperatively was cured by 18-day conservative treatment;1 who was diagnosed as delayed gastric emptying by upper gastrointestinal contrast at 16 days postoperatively was improved and then discharged from hospital by 15-day placement of intestinal feeding tube and nutrition support therapy.There were statistically significant differences in the incidences of overall complication and splenic infarction between groups (x2 =5.485,4.878,P<0.05) and no statistically significant difference in the incidence of other complications between groups (P>0.05).(3) Follow-up situations:39 patients were followed up for 12 months (range,2-64 months).During the follow-up,six patients had normal blood glucose level,and all patients had good quality of life,without recurrence.Conclusions Laparoscopic spleen-preserving distal pancreatectomy for the benign lesions of pancreatic body and tail is satisfactory in short-and long-term curative effects.The incidences of complication and splenic infarction of Kimura method are lower than that of Warshaw method.
