OBJECTIVE:To explore the implementation methods of drug price reform in China. METHODS:Current condi-tion and disadvantages of drug price mechanism in China were analyzed,the problems of the implementation of drug price reform were concluded and summarized,and the implementation methods of drug price reform were put forward. RESULTS & CONCLU-SIONS:Current condition and disadvantages of drug price mechanism in China are mainly reflected as failure of policy for maxi-mum retail price causes part of drugs to be overpriced;government-led centralized procurement of drugs results in that part of drugs are underpriced;the defects in the regulation of drug price addition rate leads to hospitals’procurement of drugs at higher price;government’s excessive interference in drug price affects the fair competition and sound development of pharmaceutical in-dustry. However,there are some problems for drug price reform,including unsound drug distribution system,a lack of fair compe-tition in modern drug market,excessive centralization of power of medical insurance authorities,absent public participation and so-cial supervision,and the“practice of using pharmacy profits to subsidize medical services”leading to wrong medical behavior. These measures were suggested to resolve above problems,i.g. reform the drug distribution system,foster modern drug market,es-tablish a medical insurance authorities-led mechanism for drug price negotiation in which multiple interest parties participate,and develop drug retail enterprises gradually replacing the outpatient pharmacies in hospitals to separate medical services from pharma-ceutical services.

Objective: To investigate the effects of the tandem repeat polymorphisms in the enhancer region (ER) of thymidylate synthase (TS) gene and the 6-bp deletion/insertion (del6/ins6) polymorphism in the 3′ untranslated region (3′-UTR) of TS gene on the clinical outcomes of gastric cancer patients treated with 5-FU-based adjuvant chemotherapy. Methods: One hundred and sixteen patients with gastric cancer were treated with 5-FU-based adjuvant chemotherapy. The polymorphisms of TSER and TS 3′ -UTR in those patients were determined by polymerase chain reaction (PCR) method. Results: Of the 116 patients, the frequencies of the TSER 2R/2R, 2R/3R and 3R/3R were 7.8% (9/116), 31.9% (37/116), and 60.3% (70/116), respectively; the frequencies of the TS3′-UTR ins6/ins6, ins6/del6 and del6/del6 were 9.5% (11/116), 41.4% (48/116) and 49.1% (57/116), respectively. The median survival period in ins6/ins6 carriers was significantly shorter than that of del6/del6 (P = 0.017) or ins6/del6 (P = 0.022) carriers. There was no significant difference in median relapse-free survival period between different TSER carriers (P > 0.05). COX multivariate analysis showed that the ins6/ins6 carriers had increased death risk (P <0.05) compared to the other two genotypes. The median no-recurrence survival period had no statistical difference between them. Conclusion: The polymorphism of TS 3 UTR ins6/del6 may be an independent factor for the prognosis of gastric cancer patients treated with 5-FU-based adjuvant chemotherapy.

Objective To assess the feasibility of the treatment of unresectable late pancreatic cancer with laparoscopic choledochojejunostomy and gastric bypass. Methods From June 2000 to December 2003, laparoscopic choledochojejunostomy and gastric bypass were successfully performed in 15 patients with unresectable late pancreatic cancer. Endoscopic noso biliary drainage (ENBD) was performed before the operation. Results All procedures were completed laparoscopically. Jaundice and hepatic function of the patients were obviously improved after the bypass. Oral nutrition was recovered after operation. The mean operative time was (100?26) min (range 70-200 min); the mean operative blood loss was (60?15) ml (range 30-120 ml); the bowel function recovery was on the 3rd-5th postoperative day; the average hospital stay was (8.1?0.7) days (range 6-13 days). Incision infection ocurred in one patient. No operative complications occurred in other patients. Conclusion Treatment of unresectable late carcinoma of the pancreas with laparoscopic choledochojejunostomy and gastric bypass aided by ENBD is a minimally invasive technique with less postoperative pain,shorter hospital stay, lower procedure related morbidity,and better oral nutrition. The life quality of patients with late pancreatic cancer can be obviously improved.

Objective To investigate The effect of TAM(2.5 uM)in the chemotherapy of HCC and its mechanism. Methods An adriamycin-resistant human HCC cell subline(Hep-3B/ADM)was established,through exposure to gradually increased concentration of ADM.Drug sensitivity was measured by MTT.Modulation of ADM-induced apop- tosis of Hep-3B/ADM cells was assessed by Flow cytometry(FCM).PKC activity was determined by applying compet- itive protein binding method.Results TAM(2.5uM )decreased the IC50 of ADM from 1.64?g/mL to 0.23?g/mL in the Hep-3B/ADM cells.TAM exhibited a 2-fold potentiation on apoptosis caused by ADM in Hep-3B/ADM cells.With TAM,PKC activity was lower than that in control groups from 30 seconds to 24 hours.But this effect of TAM could be reversed by the co-treatment of the cells with TPA.Conclusion TAM(2.5 uM)significantly en- hanced ADM-induced cytotoxicity.The mechanism is that TAM potentiates the apoptosis induced by ADM through pro- tein kinase C inhibition.

OBJECTIVE: Invastigation of macrolides in the treatment of drug effects in chronic rhinosinusit. METHOD: The 165 patients with chronic rhinosinusit were randomly divided into 80 cases of macrolides drug group and 85 cases of cephalosporins group, and therapeutic effect was observed. The therapeutic effect of macrolides was also observed in refractory chronic rhinosinusit. RESULT: Comparing macrolides group and cephalosporins group,there is not statistically significant (P > 0.05). Treatment with macrolides cefixime tablet ineffective treatment of patients for 3 months, compared before and after treatment was statistically significant (P < 0.01). Treatment with cefixime tablet macrolides ineffective treatment of patients for 3 months, compared before and after treatment was not statistically significant (P > 0.05). CONCLUSION Long-term low-dose applications of macrolides have a good effect in patients with chronic rhinosinusit, particularly for refractory chronic rhinosinusit have a significant effect.

Abnormality of sphincter of Oddi is divided into the anatomical and functional ones. Anatomical abnormality includes stenosis and insufficiency, and the dyskinesia of sphincter of Oddi is composed of hypermotility and hypomotility. Many biliopancreatic diseases are associated with the abnormality of sphincter of Oddi, which include congenital pancreaticobiliary maljunction, gallstones, primary choledocholithiasis and hepatolithiasis, post-cholecystectomy syndrome, and pancreatitis. The proper acknowledgement of abnormality of sphincter of Oddi is of importance to improve the diagnosis and therapy of corresponding biliopancreatic diseases.
