Objective To investigate the effect of cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma. Methods 124 cases with primary liver carcinoma were randomly divided into two groups:60 cases were treated by TACE and cryotherapy; the other 64 cases were simply done by TACE as control. In general, TACE was undertaken once a month and altogether three times for a course. Cryotherapy was undergone 1-3 times for a course. Results The total effective rates (CR+PR) were 45.3% for the control group and 68.3% for the combined therapy group, with an obvious difference between the two groups, 0.5,1,1.5 years survival rate were 81.3%,62.5%,43.8% respectively in the control group;93.3%,83.3%,63.3% respectively for the combined group. There was an obvious difference between the two groups of 1,1.5 years of survival rates. Conclusions Cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma is feasible with raising the effective rate and prolonging survival time.

Objective To explore changes of levels of interferon‐γ(IFN‐γ) ,interleukin‐32(IL‐32) and interleukin‐6(IL‐6) in pe‐ripheral blood and the correlation between peripheral IFN‐γ,IL‐32 ,IL‐6 and liver function level and hepatitis B virus(HBV) DNA load in HBV carriers .Methods Sixty HBV carriers ,including 39 cases of chronic HBV carriers and 21 cases of inactive hepatitis B surface antigen(HBsAg) carriers ,and 50 healthy individuals were collected .Serum levels of IFN‐γ,IL‐32 and IL‐6 ,the amount of HBV DNA and liver function were detected ,and clinical correlations were analysed .Results Compared with the control group ,ser‐um levels of IFN‐γ,IL‐32 and IL‐6 of chronic HBV carriers and inactive HBsAg carriers were significantly increased (P<0 .05) . Compared with chronic HBV carriers with low amount of HBV DNA loads and high amount of HBV DNA loads ,chronic HBV car‐riers with medial HBV DNA loads had higher serum levels of IFN‐γ,IL‐32 and IL‐6 ,but no statistically significant differences were observed(P>0 .05) .There was positive correlation between IL‐32 level and ALT level (r=0 .32 ,P<0 .05) ,and negative correla‐tion between IL‐32 level and ALB level(r= -0 .27 ,P<0 .05) .Conclusion IFN‐γ,IL‐32 and IL‐6 may play important roles in chro‐nic HBV infection ,the levels of IFN‐γ,IL‐32 and IL‐6 could be used as important indicators to assess the severity of inflammation in HBV carriers .

Objective To observe the expression of TLR4 in hepatocellular carcinoma cell line HepG2 after transient and stable HBV genome transfection. Methods Immunofluorescence flow cytometry was used to detect mean fluorescence intensity (MFI) of TLR4 and TLR4 positive cell percentage in hepetocellular carcinoma cell lines HepG2 and HepG2. 2.15. Various doses of HBV DNA plasmid were transfected into HepG2 cells with lipefectamine 2000. Immunofluoroscenee flow cytometry was used to detect MFI of TLR4 and TLR4 positive ceil rate of infected HepG2 ceils. Trypan blue staining was used to examine the sum of living cells. Results MFI of TLR4 and TLR4 positive cell rate of HepG2.2.15 cells were significantly higher than those in HepG2 cells (both P' <0. Ol). MFI of TLR4 and TLR4 positive cell rate of HepG2 cells transfected by various doses of HBV DNA were significantly higher than those in control group (all P' < 0. 01). MFI of TLR4 and TLR4 positive cell rate of infected HepG2 cells were positively correlated with the doses of HBV DNA (both P' <0. 01) and negatively correlated with the sum of living cells (both P' <0. 01). Conclusions Enhanced expression of TLR4 appeared in HepG2 cells with both transient and stable HBV infection, along with reduction of living cells.

Objective To obtain reasonable treatment by urodynamic detection and analysis in patients with diabetic cystopathy (DCP) complicated with benign prostatic hyperplasia (BPH).Methods Sixty patients with DCP complicated with BPH were selected,among the total 32 patients (duration of diabetes ＞ 12 years,blood glucose control was not ideal) were recognized as experimental group,and 28 patients (duration of diabetes ≤ 8 years,blood glucose control was stable) were recognized as control group.Using the Laborie UDS-120XLT urodynamic detection instrument,the urodynamic was detected and the international prostate symptom score (IPSS) was evaluate,and the results were compared between the 2 groups.Results There was no statistical difference in residual urine volume between experimental group and control group [(146 ±71) ml vs.(160 ±64) ml,P ＞0.05].The maximum urinary flow-rate in experimental group was significantly lower than that in control group [(5.4 ± 2.0) ml/s vs.(8.0 ± 3.2) ml/s],the symptom total score of IPSS was significantly higher than that in control group [(25.8 ± 4.1) scores vs.(22.6 ±5.0) scores],there were statistical differences (P ＜0.01).The maximum bladder capacity,compliance,incipient micturition desire volume in experimental group were significantly lower than those in control group,there were statistical differences (P ＜ 0.01).Conclusions The influence of DCP on the function of the bladder in BPH patients is significant.Urodynamic detection can provide objective basis for the selection of therapeutic methods,suitable to be operated and forecast the postoperative effect.It has an important reference value in DCP complicated with BPH patients.

OBJECTIVE To compare the difference of methods for active systemic anaphylactic reaction induced by breviscapine injection between ″Pharmacopoeia″ 2010 edition, an Attached ⅫG in Traditional Chinese Medicine lnjection Safety Test Application Guidelines ″ Anaphylactic Reaction Test″(thereafter referred to as the method of ″Pharmacopoeia″) and the Traditional Chinese Medicine, Natural Medicine lmmune Toxicity (Anaphylaxis, Anaphylactic Reaction of Light) Technology Guiding Principles in the 2005 Version (thereafter referred to as the method of ″Guiding Principle″) and provide reference for non-clinical safety evaluation of drugs. METHODS According to the methods of ″Pharmacopoeia″and ″Guiding Principle″, respectively, the effect of breviscapine injection on active systemic anaphylactic reaction of guinea pigs was investigated. The guinea pigs were divided into four groups, negative control group, positive control group, breviscapine injection 5 and 50 mg.kg-1 groups. ln the sensitization phase, the guinea pigs were ip administrered with breviscapine injection 0.5 mL each every other day for 3 times. The dose was 5 and 50 mg.kg-1 , respectively. For the method of ″Pharmacopoeia″, on the 14th and 21st days after the first sensitization, the guinea pigs were iv administrered with breviscapine injec-tion 1 mL. For the method of ″Guiding Principle″, the guinea pigs were provocated on the 12th day after the first sensitization. Each group was studied by observing the symptom of anaphylactic reaction and immune time. RESULTS For the method of ″Pharmacopoeia″, on the 14th day after the first sensitization, there was 1 guinea pig with sneezing and (or) the nose-scratching at different time in the 5 mg.kg-1 group. ln the 50 mg.kg-1 group, there was one or two cases of sneezing and (or) 1 case of nose-scratc-hing. The 5 and 50 mg.kg-1 dose groups conformed to the regulations. On the 21st day after the first sensitization, trembling occurred in the 5 mg.kg-1 group, with 1 or 2 guinea pigs sneezing and ( or) scratching the nose. There were 4 guinea pigs (4/ 4) with sneezing 1 and 3 times, cough once or twice, 1 scratching nose and urination at different time, and 1 guinea pigs (1/ 4) appeared 3 times consecutive sneezing and shivering in 50 mg.kg-1 group. The 5 mg.kg-1 group conformed to the regulations, while the 50 mg.kg-1 group did not. For the method of ″Guiding Principle″, the 5 mg.kg-1 group was weak positive or positive, with different degrees of symptoms of an anaphylactic reaction, including 3 guinea pigs scratched nasal symptoms. And the 50 mg.kg-1 group of anaphylactic symptoms including scratc-hing nose, sneezing, coughing and (or) urination, showed positive. CONCLUSION During the active systemic anaphylactic reaction of drugs non-clinical safety evaluation of drugs the advantage of either method should be brought into play. The method of ″ Pharmacopoeia″ may be used for preliminary screening of test samples. ln case pf suspected reactions, the method of ″Guiding Principle″ should be used for more detailed observations.

Objective: To investigate the effects of basic fibroblast growth factor(bFGF) on nerve regeneration of the posterior cricoarytenoid muscles(PCM) in dogs. Methods: After transection of the laryngeal recurrent nerves, the denervated PCM were reinnervated by nerve muscle pedicle implantation in 9 dogs. The animals were divided into 3 groups: bFGF and fibrin glue(FG) group(bFGF+FG), FG group and control group. Functional recovery of PCM was observed laryngoscopically. Electrophysiological acvitity and muscle contract strength were determined. Histochemical studies were demonstrated by Karnovsky and H E stain. Results: Six months after operation, functional recovery and nerve regeneration of the PCA in bFGF+FG group were the best in 3 groups (close to normal), and functional recovery in FG group was better than that in control group. The parameters of electrophysiological acvitity and muscle contract strength were different in bFGF+FG group , FG group, and control group( P

This study examined endogenous cannabinoid (ECB)-anandamide (AEA) and its cannabinoid receptors (CBR) in mice liver with the development of schistosoma japonicum. Mice were infected with schistosoma by means of pasting the cercaria onto their abdomens. Liver fibrosis was pathologically confirmed nine weeks after the infection. High performance liquid chromatography (HPLC) was employed to determine the concentration of AEA in the plasma of mice. Immunofluorescence was used to detect the expression of CBR1 and CBR2 in liver tissue. Morphological examination showed typical pathological changes, with worm tubercles of schistosoma deposited in the liver tissue, fibrosis around the worm tubercles and infiltration or soakage of inflammatory cells. Also, CBR1 and CBR2 were present in hepatocytes and hepatic sinusoids of the two groups, but they were obviously enhanced in the schistosoma-infected mice. However, the average optical density of CBR1 in the negative control and fibrosis group was 13.28+/-7.32 and 30.55+/-7.78, and CBR2 were 28.13+/-6.42 and 52.29+/-4.24 (P<0.05). The levels of AEA in the fibrosis group were significantly increased as compared with those of the control group. The concentrations of AEA were (0.37+/-0.07) and (5.67+/-1.34) ng/mL (P<0.05). It is concluded that the expression of endocannabinoids AEA and its cannabinoid receptor CBR were significantly increased in schistosoma-infected mice. Endogenous endocannabinoids may be involved in the development of schistosoma-induced liver fibrosis.
