Study of therapeutic effects of Alprostadil Injection and Composite Salvia Injection on diabetic foot / 药物评价研究

Objective To study the therapeutic effects of Alprostadil Injection and Composite Salvia Injection on diabetic foot.Methods Selected 210 cases of patients with diabetic foot who were treated in our hospital from January 2012 to December 2016,divided into three groups randomly.The group A was treated with Alprostadil Injection,group B was treated with Composite Salvia Injection,the group C was treated with Alprostadil Injection and Composite Salvia Injection.The clinical therapeutic effects of the three groups were compared,and the levels of blood lipid,urea nitrogen,creatinine,beta-globulin and urinary microalbumin before and after treatment were compared.Results After treatment,the effective rate of the group C was 92.86％ (65/70),significantly higher than that of the group A and B (P ＜ 0.05).After treatment,the levels of TG,TC and LDL-C in the three groups were significantly lower than before treatment (P ＜ 0.05),HDL-C levels were significantly higher than before treatment (P ＜ 0.05),and the group C was more significant (P ＜ 0.05).After treatment,the levels of urea nitrogen,creatinine,beta 2 and urinary microalbumin were significantly decreased in the three groups than before (P ＜ 0.05),and the group C was more significant (P ＜ 0.05).Conclusion The effect of Alprostadil Injection and Composite Salvia Injection on diabetic foot is better,which is safe and effective.

[Epidemiologic Survey of Blood Donors with HBsAg⁻/HBV DNA⁺ in Chinese Xiamen Area].

OBJECTIVE: To understand the characteristics of infections from blood donors with HBsAg⁻/HBV DNA⁺ in Xiamen area. METHODS: Donors in Xiamen area were assayed by routine ELISA and those with negative results were tested by nucleic acid amplification testing (NAT). HBsAg⁻/HBV DNA⁺ samples were tested by quantitative detection of HBV DNA. Epidemiological analysis and following up examination were conducted in HBsAg⁻/HBV DNA⁺ donors. RESULTS: Out of 130659 samples 113 were tested as HBsAg⁻/HBV DNA⁺ and with a rate of 0.09%. Among those, 62 samples were tested by quantitative detection of HBV DNA. All of the quantitative results were less than 1 × 10³ IU/ml and 93.5% (58/62) of which were less than 100 IU/ml. The possitive rate of HBsAg⁻/HBV DNA⁺ donors rose with ages. The possitive rate in male donors was higher than that in female and was lower in highly educated ones. Students and public servants had a lower positive rate. CONCLUSION: The possitive rate of HBsAg⁻/HBV DNA⁺ donors is higher in Xiamen and the distribution of possitive donors has certain epidemiological characteristics. It is necessary to mobilize and recruit more people with a lower rate of HBsAg⁻/HBV DNA⁺ infection.

Molecular characteristics of occult hepatitis B virus from blood donors in southeast China.

The characteristics of 30 carriers with occult hepatitis B virus (HBV) infection (OBI) were compared with those of 30 individuals diagnosed as being HBV carriers at the time of blood donation, 60 asymptomatic carriers, and 60 chronic hepatitis patients. The prevalence of genotype C was significantly higher in carriers with OBIs than in any other HBsAg-positive (HBsAg(+)) group (P < 0.001). Specific amino acid substitutions in the regions from amino acids 117 to 121 and amino acids 144 to 147 located in the major hydrophilic region of the S gene were associated with carriers with OBIs (P < 0.01 for carriers with OBIs versus HBsAg(+) donors, carriers with OBIs versus HBsAg(+) asymptomatic carriers, and carriers with OBIs versus HBsAg(+) chronic hepatitis patients). G145R was the major variation in the HBV isolates responsible for local occult HBV infections.

[Surveillance for occult HBV infection and HBsAg variants in blood donors].

Occult hepatitis B virus (HBV) infection status of blood donors in a southern city in China was investigated by immunological assays and nucleic acid testing. Overall, 17 (0.19%, 95% CI: 0.11%-0.30%) of the 9023 HBsAg negative samples were found to be positive for the presence of HBV DNA. "A" epitope sequences were obtained from 14 among them. Mutation(s) in aa124-aa147 existed in 6 (42.9%, 6/14) samples and 4 (66.7%, 4/6)were G145R mutation. Ratio of genotype C in occult donors (10/17) was statistically higher than HBs-positive donors (0/15, P<0.01), which implied that HBV genotype C leaded to occult infection more easily.
