Neamine inhibits growth of pancreatic cancer cells in vitro and in vivo / 华中科技大学学报（医学）（英德文版）

Neamine, a non-toxic derivative of neomycin, has recently been shown to have antitumor activities in various types of cancers. However, its effect on pancreatic cancer is still unknown. The study aimed to investigate its antitumor activity on pancreatic cancer and the underlying mechanisms. MTT assay was used to observe the effect of neamine on angiogenin (ANG)-induced AsPC-1 cell proliferation. Tissue microassay and immunofluorescence staining were used to detect the expression of ANG and its nuclear translocation, respectively. Tumor xenografts were established by subcutaneous inoculation of AsPC-1 pancreatic cancer cells into the right flanks of nude mice, and neamine was injected subcutaneously. Immunohistochemistry was done to observe the expression of ANG, CD31 and Ki-67 in tumor xenografts. It was found that neamine blocked the nuclear translocation of ANG effectively and inhibited ANG-induced AsPC-1 cell proliferation in a dose-dependent manner. Neamine had anti-tumor effects on AsPC-1 xenograft models. Consistently, neamine reduced the expression levels of ANG, Ki-67 and CD31 in tumor xenografts. It was concluded that neamine may be a promising agent for treatment of pancreatic cancer.

Risk factors associated with bacteriological cure, new infection, and incidence of clinical mastitis after dry cow therapy with three different antibiotics

Factors affecting bacteriological cure rates (BCR) and new intramammary infections (IMI) during the dry period as well as clinical mastitis (CM) during early lactation were investigated in 414 German Holstein dairy cows receiving dry cow therapy. Cows were treated with either benethamine benzylpenicillin (300,000 IU), penethamate hydriodide (100,000 IU), and framycetin sulphate (100 mg, n = 136), or cefquinome (150 mg, n = 135), or benzathine cloxacillin (1,280 mg, n = 143). Overall BCR, IMI, and CM at parturition were 86.4%, 20.7%, and 4.3%, respectively. The three antibiotic treatments differed only in BCR, with cloxacillin yielding better results than the others. Udder quarters from cows with > 4 lactations had a higher risk of IMI and CM at calving. Chronic changes in udder tissues were linked to a lower BCR and were associated with a higher risk of CM during early lactation. The risk of CM at calving was higher in udder quarters with unspecific or subclinical mastitis before drying off. In conclusion, with antibiotic dry cow therapy, age and health status of the udder appear to be major determinants of IMI and CM during the dry period and early lactation, while BCR was associated with the antibiotic type and udder tissue status.

HIV-1 Rev and related inhibitors / 药学学报

HIV-1 Rev is an indispensable regulatory factor of the virion protein expression. The interaction between Rev and RRE RNA accelerates the nuclear export of viral mRNA. The unspliced and singly spliced mRNA will be degraded in the absence of Rev, resulting in the interception of HIV-1 replication at the same time. The pivotal role that Rev plays in HIV-1 replication as a trans-acting factor makes it a new target in the research of AIDS drugs. In this review, the function of Rev, Rev-RRE interaction, as well as their related inhibitors are reported.

Prescription pattern for treatment of hemorrhoids under the universal coverage policy of Thailand.

The Universal Coverage Policy (UCP) or "30 Baht Scheme" was launched in Thailand in 2001. The policy caused a cutback in the budgets of all public hospitals and health service centers. Traditional medicine was then viewed as an alternative to save costs. This study examines whether this had any influence on hemorrhoid treatment prescription patterns, ratio of traditional/modern medicine, or the cost of hemorrhoid treatment after the UCP was implemented at a community hospital. The traditional medicine prescribed was Petch Sang Kart and the modern alternative was Proctosedyl. All hemorrhoid prescriptions at a community hospital from October 2000 to January 2003 were surveyed. Segmented Regression Analysis was applied to evaluate prescription trends, the ratios between the types of medicine, and the hemorrhoid treatment cost. A total of 256 prescriptions were analyzed. The average number of traditional medicine prescriptions per month were more than modern medicine (41 versus 16). During the study period, the trend of modern medicine use and the treatment cost was decreased (p < 0.01). The ratio of traditional/modern medicine increased 0.2 times (p = 0.02).

Randomized, double-blind trial comparing topical nitroglycerine with xylocaine and Proctosedyl in idiopathic chronic anal fissure.

OBJECTIVE: To compare symptomatic relief, healing, and changes in maximal anal resting pressure with the use of topical formulations in patients with chronic anal fissure. METHODS: Sixty-four consecutive patients with chronic anal fissure were randomized into 4 groups that received, in a double-blind manner, a topical ointment that contained 0.2% nitroglycerine (GTN), 5% xylocaine, Proctosedyl (hydrocortisone acetate, heparin, framycetin sulfate, esculoside, ethoform, butoform) or petroleum jelly (Vaseline), to be applied twice daily. Patients were reviewed at 2-week intervals for 6 weeks. Anal manometry was done before, and 20 minutes after, the first application of the ointment. RESULTS: There was significant (p < 0.0001) reduction in mean anal resting pressure after application of GTN, but not any other ointment. Of 16 patients receiving GTN, complete pain relief occurred in 6 and 15 patients after 2 and 4 weeks of treatment, respectively; this was more frequent than in the other 3 groups. At 6 weeks also, complete pain relief occurred more often with GTN than with Vaseline or xylocaine. After 4 weeks of treatment, 3 patients on GTN had complete healing of fissure as compared to one each in the xylocaine and Proctosedyl groups and none in the Vaseline group. At 6 weeks, healing of fissure had occurred in 15 of 16 patients receiving GTN as compared to 4 receiving Vaseline, 11 receiving xylocaine, and 12 on Proctosedyl. CONCLUSIONS: Topical nitroglycerine produces 'chemical sphincterotomy' with reduction in mean anal resting pressure. Pain relief and healing of fissure occurred earlier with GTN than with other treatments. GTN should be considered as the treatment of choice for the non-surgical management of patients with chronic anal fissure.

Esperson(R), a new topical steroid ointment containing 0. 05% 17-Desoxymethasone,. was used in several kinds of dermatoses. Framycetin which was isolated and uientified by the research organisation of Roussel Laboratories (SOFRAPEN) in 1950 from culture broths of a strain of Streptomyces species is a wide spectrum antibiotics on various bacterial infectious diseases. Total 50 patients including 10 cases of 2ndary infected Atopic dermatitis, 10 of infected Contact dermatitis, 6 of infected Seborrheic dermatitis, 7 of infected Neurodermatitis, 3 of infected Chronic dermatitis, 5 of lmpetigo, 2 of infected Nummular eczema, 2 of infected Infantile ecze;na, 1 of infected Intertrigo, 1 of Eczematoid Otitis extema, 1 of 2nd degree Bum, 1 of infected Pruritis ani, 1 of infeeted 1nsect bite. were treated with Frason(R) (0.05% 17-desoxymethasone & 0.5% Framycetin combination). Among these 50 patiants, we observed excellent effects in 7 patients (14%), good effect in 29 patients (58%), fair effect in 10 patients (20%), Totally 36 patients (72%) revealed excellent to good therapeutic effects on their skin conditione after unoccluded application of Frason(R). 3 times daily for about 14 days. There was no sid ffect in all subjects after application of Esperson-F.
