OBJECTIVE: To draw the attention of our country and the concerned party on the shortage of certain drugs. METHODS: Based on the drug shortage condition in our hospital in recent years, we analyzed the reasons for drug shortage, put forward the solution and summarized the clinically indispensable categories. RESULTS & CONCLUSIONS: We should draw experiences from US by solving shortage problem of certain drugs through the co-efforts of government, manufactures and medical institutions to satisfy patients' needs of disease prevention and treatment.

Objective To explore the effect of psychological intervention on patients with advanced ovarian cancer. Methods A total of 80 patients with advanced ovarian cancer patients combined with carboplatin or Western him paclitaxel combined with cisplatin in the treatment of patients, the implementation of grouping according to nursing, patients in the control group for routine care, patients in the observation group in the control group on the basis of psychological nursing. The two groups were observed and compared the clinical effect of intervention. Results The observation group the effective rate of the treatment and nursing satisfaction rate were significantly higher than the control group; the implementation of group nursing, observation group patients psychological status and improve the psychological status of patients in the observation group after treatment were better, and the control group have obvious difference. Conclusion For patients with advanced ovarian cancer chemotherapy, combined with psychological intervention on the basis of routine nursing, can significantly improve the treatment efficiency, improve the psychological status of patients, is worthy of clinical application

Objective To investigate the association of age,precipitating factors and seasons of symptom onset of urinary stones with patients who have or have no family history. Methods The questionaires were used to survey 360 urinary stone cases with family history,1200 cases without family history and 1000 normal controls in Chongqing Area. Results In the 360 patients with family history,the morbidity rates of the first degree relatives and second degree relatives were 10.71%(147/1372) and 1.68%(54/3214), respectively.But in those without family history,the morbidity rates of the first degree relatives and second degree relatives was 0.66%(23/3480) and 0.12%(9/7345),respectively.Among the patients with family history,the mean age of morbidity for the males (26.35 years) was younger than that of the females (36.4 years, t=1.75,P 0.05).There was no significant difference of the precipitating factors and symptom onset seasons between patients with or without family history,while the enviropmental factors had significant effects on the morbidity of urinary stone patients,without regard to family history(? 2=0.23, P

Objective To observe and analyze the correlation between the DNA methyltransferase-3B (DNMT3B) gene single nucleotide polymorphisms (SNP) rs 1569686 and the susceptibility to colorectal cancer (CRC) in Tianjin Han population.Methods A case-control study was performed.89 CRC patients and 94 normal controls were examined,and Sequenom MassArray system was applied to detect the genotype of rs1569686 in DNMT3B gene polymorphisms.The association results were analyzed of the SNP and CRC.Results The frequencies of genotypes TT,GT and GG at SNP rs1569686 were 74.2％,24.7％ and 1.1％ in CRC patients respectively,which there were no significant differences from that in controls(73.4％,23.4％ and 3.2％; P＞0.05).Conclusion It suggests that the SNP rs1569686 of DNMT3B gene may not be related to susceptibility of CRC in Tianjin Han population.

Objective To investigate the clinical significance of changes in vascular endothelial cells during the development of glucocorticoid-induced avascular necrosis of femoral head(GANFH),and the preventive and therapeutic effects of "Cugusu Keli",a mixture of traditional Chinese medicines,on GANFH in rabbit.Methods Forty-eight New Zealand white rabbits were randomly assigned to four groups,12 in each,as control group,model group,therapy group and prevention group.The contents of plasma von Willebrand's factor(vWF),6-keto-prostaglandin F1?(6-keto-PGF1?)and the activity of plasminogen activator inhibitor 1(PAI-1)were determined at the 2nd,4th,6th,8th and 12th week after treatment.Meanwhile,rabbits were sacrificed at the 4th,8th and 12th week,and both femoral heads of all rabbits were obtained for histopathological examination.Results Compared with control group,the level of vWF and activity of PAI-1 in model group were elevated since the 4th and the 2nd week,while the level of 6-keto-PGF1? increased since the 4th week(P0.05).Compared with the model group,the level of vWF and activity of PAI-1 in therapy group was lowered,while the level of 6-keto-PGF1? increased(P

Aim To investigate the protective effects of omapatrilat on human umbilical vein endothelial cells (HUVECs) injury induced by angiotensin Ⅱ (AngⅡ) in culture. Methods Cultured HUVECs were randomly divided into 4 groups:①control; ②AngⅡ;③omapatrilat and ④AngⅡ+omapatrilat. Lactate dehydrogenase (LDH) leakage was evaluated by spectrophotometer and cell cycle by flow cytometry (FCM); Nitric oxide (NO) was measured by colorimetry and endothelin-1 (ET-1) by radioimmunoassay. Results 10 -7 mol?L -1 AngⅡ significantly increased LDH leakage and ET-1 release, and this increase was inhibited by omapatrilat (10 -6 mol?L -1). Omapatrilat promoted HUVECs proliferation and NO release. Conclusion Omapatrilat can protect human umbilical vein endothelial cells injury induced by angiotensin Ⅱ in culture, suggesting that it may play an important role in prevention and treatment of vascular diseases.

Objective: To set up the animal model of precancerous lesion of rats' pancreatic acinar cellular cancer,and to learn estrogen's effect on this lesion's biological feature and K-ras gene mutation. Methods: male Wistar rats were injected Azaser-ine 30mg/kg(ip). Some rats received Estradiol-17 P Valerate(0.18mg/100g/2weeks, im) .4 months later, rats'pancreas were autopsied and K-ras gene mutation were detected by PCR-SSCP method. Results : The incidence of AACN were very high. The incidence of K-ras gene mutation was 42.1% in rats without estrogen and 25.6% with estrogen. Conclusion: Azaserine could induce precancerous lesion of rats' pancreatic acinar cancer successfully, K-ras gene mutation was early change during this process Estrogen could inhibit this precancerous lesion's happen and development to some degree.
