China Pharmacist 2015;18(12):2119-2122
Objective:To investigate the adverse drug reactions ( ADR) caused by carbapenem antibiotics and discuss the influen-cing factors to provide reference for the rational use of carbapenems in clinics. Methods:The ADR caused by carbapenems from March 1, 2008 to August 1, 2014 in our hospital were statistically analyzed. Results:Totally 73 cases of ADR were caused by carbapenems. The number of ADR for men and women was similar. The ADR occurred in 80-year-old people with more frequency. The incidence of ADR on the first day of administration was relative high. The ADR were mainly manifested as skin and appendages disorders and nerve system damage. Conclusion: Great attention should be paid to the ADR of carbapenems and the state of patients. The medication should be adjusted in the patients with declined renal function and nerve system basic diseases in order to reduce the damage of ADR.

Journal of Acupuncture and Tuina Science 2004;2(2):40-42
To search for the best method in treating prolapse of lumbar intervertebral disc, the cases of prolapse of lumbar intervertebral disc were treated by Tuina plus acupuncture. The cure rate was high, the course of treatment was short and the effect was satisfactory. Tuina can relax muscles and tendons,promote the blood circulation, acupuncture can warm the meridians to disperse cold pathogen, promote the blood circulation to remove blood stasis, and the combination of these two treatments can enhance the therapeutic effect.

Objective To study whether vancomycin dosage 2 g daily in Chinese adult patients would achieve the target serum trough concentration of 10-20 mg/L.Methods The data of 122 adult inpatients under therapeutic drug monitoring while receiving vancomycin were collected from September 2011 to December 2012.The correlation between vancomycin trough concentration and dosage,age,sex,body weight,concomitant medications were analyzed retrospectively.Results Vancomycin trough concentration was below the target concentration in 62.1% of the included patients.Age is an independent risk factor for attainting target concentration.Serum concentration was below target concentration in 70.0% of the patients below 60 years of age.Serum concentration was above target concentration in 62.5% of the patients above 60 years of age.Conclusions Clinicians and pharmacists should assess the dosage regimen of vancomycin cautiously,and age should be considered especially as an independent risk factor.

Objective To investigate the relationship between IgG antibody titer in pregnant women with maternal-fetal ABO blood incompatibility and hemolytic disease of fetuses and newborns.Methods From January 31 2009 to January 31 2010,1269 singleton pregnant women who were suspected to have maternal fetal ABO blood incompatibility in Department of Obstetrics and Gynecology,Southwest Hospital,Third Military University were collected.Anti-A or anti-B IgG titers of them were detected at 28-30 gestational age,and umbilical cord blood were taken when delivery and hemolytic disease of the newborn serological test were done to diagnose hemolytic disease of the newborn (HDN).The relationship between the titers and incidence of fetal or neonatal hemolytic disease was retrospectively analyzed by Kendall tau rank correlation.Results No IgG of anti-A or anti-B in serum were found in 58.4% (741/1269) pregnant women,while the antibody titer of 5.1% (65/1269) pregnant women were more than or equal to 1 ∶ 128.When they were tested again at 36 gestational week,the titer of 17 cases increased twice but lower than 1 ∶ 512.No signs of intrauterine hemolysis,such as edema,ascites and pleural effusion,were found.Three hundred and eighty neonates (29.9%,380/1269) were diagnosed as HDN.Among which,12 cases (3.2%,12/380) showed mild anemia and (or) jaundice within 24 hours after delivery.There was positive correlation between incidence of neonatal hemolysis and antibody titer(Tb=-0.293,P<0.01).The incidence of HDN increased from 85.4% (35/41) in women with antibody titer of 1 ∶ 128 to 5/5 inwomen with antibody titer at 1 ∶ 512 (x2=108.906,P<0.01).Among 380 HDN neonates,322 cases were transferred to neonatal intensive care unit for phototherapy based comprehensive therapy,and two underwent exchange transfusion.All patients were cured.Conclusions The intrauterine hemolysis incidence of patients with suspected maternal-fetal ABO blood incompatibility is very low,and no special care is required during pregnancy.Anti-A or anti-B tests during pregnancy is helpful in early diagnosis and management of HDN.

OBJECTIVE: To verify the biocompatibility between diamond-like carbon (DLC) film and human vascular endothelial cells and to provide evidences for construction of artificial mechanical valve prosthesis. METHODS: Nanophase DLC film was deposited using pulse laser deposition, while vascular endothelial cells derived from human umbilical vein was cultured with nanophase DLC film in vitro. Cell growth and adhesion were observed under inverted microscope, and cell proliferation was measured with MIT method. In addition, levels of nitric oxide (NO) and prostacyclin (PGI2) were measured in the DLC group and blank control group in order to evaluate their activities. RESULTS: Adhesion, proliferation, and growth of vascular endothelial cells derived from human umbilical vein were great on the surface of nanophase DLC film. There were no significant differences in the levels of NO and PGI2 between DLC group and blank control group (P > 0.05), showing that nanophase DLC film had no effect on activity of vascular endothelial cells derived from human umbilical vein. CONCLUSION: Nanophase DLC film has a good biocompatibility, and it can become an ideal material of tissue-engineering artificial mechanical valve prosthesis.
