Objective:To investigate the effects of thalidomide on vascular endothelial growth factor(VEGF) and quality of life in patients with primary hepatocellular carcinoma after transcatheter arterial chemoembotization.Methods:A total of 60 patients with HCC,who were treated with transcatheter arterial chemoembolization (TACE) in Affiliated Hospital of Chengde Medical University from January 2014 to January 2016,were randomly divided into group A (n=30)and group B (n=30).Group A was treated with Thalidomide in combination with TACE,oral 200 mg every night for 1 month;group B was treated with TACE alone.The levels of VEGF in the two groups were detected before treatment and 3 weeks after treatment;the quality of life of patients before treatment and 1 month after treatment was evaluated by quality of life scale (QOL);the weight of two groups before and after treatment and adverse reactions during treatment were compared.Results:There was no significant difference in VEGF levels between the two groups before treatment (P＞0.05).After treatment,the levels of VEGF in the two groups were higher than those before treatment,and the VEGF levels in the group A was significantly lower than that in the group B,the difference was statistically significant (P＜0.01).There was no significant difference in QOL score and body weight between the two groups before treatment (P＞0.05).The QOL scores of the two groups after treatment were lower than those before treatment,but the QOL scores of patients in group A were significantly higher than those in group B (P＜0.05).There was no significant difference in weight between the two groups before and after treatment (P＞0.05).In group A,1 patients (3.33％) had severe somnolence,2 (6.67％) patients stopped taking thalidomide due to severe dry mouth,and the remaining 27 patients were able to tolerate.Conclusion:Thalidomide combined with TACE in the treatment of patients with HCC can reduce the levels of VEGF and improve the quality of life of cancer patients,which is worthy to be popularized in clinic.

Objective To investigate the correlation between the formation of pigmented biliary calculus and biliary H.pylori infection.Methods Bile from 35 patients with pigmented biliary calculus and 10 healthy controls was cultured for aerobic,anaerobic and H.pylori.The expression of H.pylori- DNA in bile,bile duct mucosa and pigmented calculus were determined by PCR.The expression of H. pylori associated protein in bile duct mucosa was determined by Western-blot and Warthin-Starry staining.Results H.pylori culture was negative in all bile samples.In 35 patients with biliary pigmen- ted calculus,H.pylori was detected by PCR in the center of calculus,bile and bile duct mucosa of 14.29%,31.43% and 56.67% patients,respectively.Among H.pylori-DNA positive bile samples,7 contained anti-CagA antibodies,and 6 contained Vac A.in addition to Vacuolating cytotoxin(35000), glycoprotein(30000),Urase Band Urase A.Bacteria resembling H.pylori by Warthin-Starry stainning were found in 7 of 30(23.33%)bile duct mueosal samples from patients with biliary pigmented calculus. H.pylori-DNA and its associated protein were not detected in all bile and bile duct mucosae samples from the healthy controls.Conclusions The evidence of H.pylori-DNA and its associated protein in biliary system might indicate the role of H.pylori in the formation of biliary pigmented calculus.

Objective To explore the effect of different dosage of radial extracorporeal shock waves on fracture disunite and bone nonunions.Methods 42 patients were divided into 3 groups based on the different shock dosage, every group contained 14 patients and the shock dosages were 1000, 2000 and 3000 in Groups A, B and C respectively. All patients accepted the therapy for 3 times and followed up with X rays. Results 3 months after treatment, calluses were formated iin 2(14.7%), 8(57.1%) and 8(57.1%) patients in 3 groups respectively,which was lower in Group A than in Groups B and C (P<0.05), but there was no significant difference between Group B and Group C (P>0.05). 9 months after treatment, the corresponding cure rates were 28.6%, 85.7% and 78.6% in 3 groups respectively. The cure rate was lower in Group A than in Groups B and C (P<0.05), but there was no significant difference between Groups B and C (P>0.05). Conclusion The radial extracorporeal shock waves had dose-dependence and saturation for the shock dosage, 2000 is the optimal choice

OBJECTIVETo examine the effect of acetylcholine (ACh) on the electric activities of pain-excitation neurons (PEN) and pain-inhibitation neurons (PIN) in the hippocampal CA1 area of normal rats or morphinistic rats, and to explore the role of ACh in regulation of pain perception in CA1 area under normal condition and morphine addiction.

METHODSThe trains of electric impulses applied to sciatic nerve were set as noxious stimulation. The discharges of PEN and PIN in the CA1 area were recorded extracellularly by glass microelectrode. We observed the influence of intracerebroventricular (i.c.v.) injection of ACh and atropine on the noxious stimulation-evoked activities of PEN and PIN in the CA1 area.

RESULTSNoxious stimulation enhanced the electric activity of PEN and depressed that of PIN in the CA1 area of both normal and addiction rats. In normal rats, ACh decrease the pain-evoked discharge frequency of PEN, while increased the frequency of PIN. These effects reached the peak value at 4 min after injection of ACh. In morphinistic rats, ACh also inhibited the PEN electric activity and potentialized the PIN electric activity, but the maximum effect appeared at 6 min after administration. The ACh-induced responses were significantly blocked by muscarinic receptor antagonist atropine.

CONCLUSIONCholinergic neurons and muscarinic receptors in the hippocampal CA1 area are involved in the processing of nociceptive information and they may play an analgesia role in pain modulation. Morphine addiction attenuated the sensitivity of pain-related neurons to the noxious information.
