ObjectiveTo evaluate the clinical efficacy of gelatin sponge particles chemoembolization for liver metastasis of gastric cancer patients. MethodsThe clinical data of 5 cases from December 2009 to July 2010 with gelatin sponge particles chemoembolization for liver metastasis after radical gastrectomy patients was analyzed retrospectively. ResultsVarious degrees of necrotic lesions were observed in all cases, 6 months after operation, 1 case received complete remission (CR),3 cases with partial remission (PR), 1 case with stable condition (SD), the total effective (CR + PR) rate was 80%(4/5). Conclusion Gelatin sponge particles chemoembelization for liver metastasis of gastric cancer has achieved a good shortterm effect,while the long-term efficacy remains to be identified.

Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.

Objective To evaluate the safety and efficacy of combined transcatheter intraarterial chemoembolization with 350-560 μm gelatin sponge particles and lobaplatin (GSPs-TACE) and oral Chinese herb medication Huaier granules in patients with hepatocellular carcinoma (HCC).Methods This is a case-control,single-institution clinical trial.31 HCC patients receiving GSPs-TACE (group A) were matched with 31 patients receiving GSPs-TACE and Huaier granules (group B).Tumor response was evaluated by CECT using response evaluation criteria in solid tumors at 1 month after initial GSPs-TACE.The overall survival was calculated from the data of initial GSPs-TACE using the Kaplan-Meier method.Results The overall mean follow-up period was 28.7 (range 12-42) months.The overall 6-and 12-month survival rates in group A and group B were 90.3% and 80.6% vs 100% and 93.5%,respectively.There was statistically significant difference in 12-month survival rates (x2 =5.213,P <0.05).Median survival time respectively was 17.1 and 20.6 months(x2 =0.745,P >0.05).The average TACE times were (4.1 ±7.3) and (2.9 ±8.7) respectively in group A and group B (P =0.01).Tumor objective response rate was statistically different in 6-and 12-month in two arms(x2 =5.945,6.384,P <0.05).There was no statistically significant difference in complications (respectively x2 =0.435,0.485,2.037,0.137,0.325,all P > 0.05).Conclusions Huaier granules combined with transcatheter intraarterial chemoembolization with 350-560 μm gelatin sponge particles and carboplatin for HCC is safe and effectively prolongs patients' survival.

Objective To discuss interventional procedures before feeding tube placed in the DSA guidance,influence postoperative enteral nutrition support for the presence of nutritional risk of clinical outcomes in elderly patients with hepatocellular carcinoma. Methods 33 patients acquired with interventional therapy of hepatic carcinoma were selected as the study group.All of patients un-derwent preoperatively the nutritional risk screening and insertion of nasogastric feeding tube under DSA.Enteral nutritional support by the nasogastric feeding tube was used after interventional therapy.33 similar patients underwent parenteral nutritional support af-ter international therapy were selected as the control group.The change of the nutritional indexes,the incidence of the systemic in-flammatory response syndrome,the incidence of infection,and the length of hospital stay after operation were compared between the two groups.Results There were no significant differences in the plasma albumin levels and body weight changes compared between the two groups (P >0.05).However,the incidence of infection and the length of hospital stay were lower significantly in the study group than in the control group (P >0.05).Conclusion The nutritional risk screening before interventional treatment is necessary for the elder patients with hepatic carcinoma.The patients with nutritional risk can be placed the nasogastric feeding tube preopera-tively under DSA,and perform combined nutritional support to promote the recovery of nutritional state after operation.

OBJECTIVETo study the protective effect of limb ischemic preconditioning against liver ischemia/reperfusion injury in the rat.
METHODSRats were randomly divided into four groups (n = 8): (1) Sham group (S group), rats without ischemic preconditioning (IPC), (2) Ischemia/reperfusion (I/R) without IP (I/R group); (3) Rats with 5 min IPC (IPC group); (4) Rats with lower limbs IPC and repeated three times (remote ischemic preconditioning, RPC group); The rats were subjected to 60-min sustained liver ischemia followed by 180-min reperfusion except S group. All ischemia rats were only subjected to 70% liver ischemia. Finally, blood and liver samples were obtained to determine the activity of ALT and AST, liver wet/dry weight (W/D), PMN counts and pathology.
RESULTSAll IPC group and RPC group had obviously lower levels of ALT, AST, W/D, PMN counts than that of the I/R group (P < 0.01).
CONCLUSIONThe limb ischemic preconditioning has a protective effects against liver ischemia/reperfusion injury in the rat, possibly are due to suppression of liver inflammatory reaction, improvement of liver microcirculation.

The electrospray ionization-ion mobility spectrometric (ESI-IMS) technique has the potential as an analytical separation tool in analyzing polypeptides and amino acids for fast screening unknown samples in anti-chemical and biological terror attacks. A method for detecting several polypeptides and amino acids was developed based on ESI-IMS using air as drift gas at room temperature. The ion mobility of four amino acids and two polypeptides dissolved in methanol was determined on the system at elution rate of 2 mL/ min. The spectra of these compounds had characteristics of finger-printing maps. The limit of detection of this instrument for Substance P could reach 855 ng / mL in 1 min. The results showed that a small, self-contained ESI-IMS instrument with reservoirs of air could be used to quickly detect and accurately identify polypeptides and amino acids.

OBJECTIVE: To investigate the efficacy and safety of nebulized inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease. METHODS: From December 2016 to April 2018,440 cases of lower respiratory tract infection with cough and wheezing were hospitalized for treatment in the Department of Respiratory Medicine of Children's Hospital of Soochow University,Chengdu Women's & Children's Central Hospital and Dalian Children's Hospital of Dalian Medical University. The children were selected and randomly divided into terbutaline sulfate for injection group(Group A),terbutaline sulphate solution for nebulization group(Group B)and control group(Group C). The efficacy and adverse reactions of the three groups were compared. RESULTS: The scores of wheezing symptoms in group A and group B decreased more significantly than those in group C(P<0.05). Group A and group B had a certain influence on heart rate,and the heart rate at 30 minutes and 60 minutes after nebulization was higher than that of group C. In addition to the effect on heart rate,no other adverse reactions were found in group A and group C;one patient in the group B developed arm tremor and disappeared after stopping the drug. CONCLUSION: Inhalation of terbutaline sulfate for injection in the treatment of children with wheezing disease can shorten the treatment time and effectively improve the clinical treatment effect. The clinical efficacy is comparable to that of terbutaline sulphate solution for nebulization,and it is safe and worthy of clinical application.
