@#AIM: To compare the clinical effects of retinal detachment with choroidal detachment(RD/CD)treatment by posterior subcapsular Tenon injection triamcinolone acetonide and intravenous drip of dexamethasone combined vitrectomy.<p>METHODS: Totally 52 cases(52 eyes)of RD/CD patients in our hospital from March 2014 to October 2017 were retrospectively reviewed. According to the preoperative intervention methods, the patients were divided into two groups: A group and B group. Group A(27 cases, 27 eyes)received intravenous drip of dexamethasone once a day 3-5d before operation. Group B(25 cases, 25 eyes)received posterior subcapsular Tenon injection triamcinolone acetonide 5d before operation. The intraocular pressure, CD, retinal reattachment, visual acuity and complications were measured before and after the intervention.<p>RESULTS: After intervention, the intraocular pressure of group B was 8.09+3.56mmHg, which was significantly higher than 5.65+2.19mmHg before intervention in group B and 6.25+2.53mmHg after intervention in group A. The difference was statistically significant(<i>P</i><0.05). After intervention, the CD height of group A and B was 3.98(1.01, 5.34)mm and 0.92(0.03, 3.88)mm, significantly lower than that in group A and B before intervention, which was 5.22(3.14, 6.64)mm and 5.16(3.34, 7.71)mm. CD loci 6.0(3.0, 10.0)and 3.0(0.0, 6.0)were significantly lower than those of 11.0(9.0, 12.0)and 10.0(8.0, 12.0)before intervention. The CD height and the number of CD loci in group B were lower than those in group A(<i>P</i><0.05). From the last follow-up, the success rate of retinal reattachment in groups A and B were 78% and 96%, respectively(<i>P</i>>0.05). At 1, 3mo and the last follow-up, the visual acuity of group A was 1.69±0.79, 1.39±0.72 and 1.38±0.61 better than that of group A before intervention 2.06±0.28. The visual acuity of group B was 1.42±0.66, 1.29±0.56 and 0.97±0.51 better than that of group A before intervention 2.02±0.58. The visual acuity of group B was better than that of group A at the last follow-up, with statistical difference(<i>P</i><0.05). At 1 and 3mo after operation, 4 eyes in group A had high intraocular pressure, which was significantly lower than that of 11 eyes and 12 eyes in group B(<i>P</i><0.05). At the last follow-up, there was still 1 eye with high intraocular pressure in group A and 2 eyes in group B(<i>P</i>>0.05).<p>CONCLUSION: In the treatment of RD/CD, the effect of posterior subcapsular Tenon injection triamcinolone acetonide with vitrectomy is better than that of intravenous drip of dexamethasone combined vitrectomy, the intraocular pressure should be monitored after operation. If high intraocular pressure occurs, appropriate drug control or removal of triamcinolone acetonide from the posterior Tenon capsule is required.

Comparison of Therapeutic Efficacy of 2 Kinds of Methotrexate Administration Routes Combined with Complete Curettage of Uterine Cavity in the Treatment of Cesarean Scar Pregnancy / 中国药房

OBJECTIVE:To compare clinical efficacy and safety of intravenous dripping of methotrexate and uterine arterial perfusion embolization combined with complete curettage of uterine cavity (CCUC) in the treatment of cesarean scar pregnancy (CSP).METHODS:A total of 90 CSP patients were randomly divided into group A and B,with 45 cases in each group.Group A was given Methotrexate (MTX) injection 50 mg/m2 intravenously before CCUC.Group B received Seldinger catheterization in supine position before CCUC,and was given sequential infusion of MTX injection 50 mg/m2 and gelatin sponge particles into the uterine artery;the catheter was removed after satisfactory embolization by imaging examination.The levels of β-HCG of 2 groups were reexamined every 24 h,and CCUC was performed when serum β-HCG level was below 1 000 mU/mL.Perioperative bleeding volume,postoperative bleeding volume,the time of blood β-HCG returning to normal,the time of menstruation returning to normal,hospitalization time as well as the lesion diameters,the levels of blood β-HCG,the occurrence of compliance and ADR before and after treatment were compared between 2 groups.RESULTS:The intraoperative bleeding amount and postoperative bleeding amount of group B were significantly lower than those of group A,while the time of blood β-HCG returning to normal,the time of menstruation returning to normal and hospitalization time were significantly shorter than group A,and the incidence of total compliance was significantly lower than group A,with statistical significance (P＜0.05).Before medication,there was no statistical significance in lesion diameters between 2 groups (P＞0.05).Before CCUA,the lesion diameters of 2 groups were significantly smaller than before medication,and the group B was significantly smaller than group A,with statistical significance (P＜0.05).Before medication,there was no statistical significance in blood β-HCG levels between 2 groups (P＞0.05).Before and after CCUC,blood ββHCG levels of 2 groups were significantly lower than before medication,and the group B was significantly lower than group A,with statistical significance (P＜0.05).There was no statistical significance in the incidence of ADR between 2 groups (P＞0.05).CONCLUSIONS:Compared with methotrexate by intravenous drip,methotrexat by uterine artery embolization combined with CCUC for CSP can effectively reduce intraoperative bleeding amount,promote the decrease of blood β-HCG and menstrual recovery,and contribute to the reduction of complication risk with good safety.

Objective To investigate the clinical effect of continuous infusion of vancomycin in the treatment of intracranial infection secondary to traumatic brain injury by intrathecal injection and intravenous infusion. Methods 96 patients with traumatic brain injury from December 2015 to March 2017 were randomly divided into study group and control group, the patients were randomly divided into study group and control group (n=48).The study group of patients with continuous drainage combined with vancomycin intrathecal injection treatment, the control group of patients with continuous drainage combined with vancomycin intravenous infusion. The clinical effects of two groups of patients with secondary intracranial infection after traumatic brain injury were recorded.

Excel-based Design of Intermittent Intravenous Drip Dose Regimen of Antibiotics / 中国药房

OBJECTIVE:To design intermittent intravenous drip dose regimen of antibiotics. METHODS: The pharmacokinetic data were computed using the multidoses function method taking cefazolin,ceftriaxone and amikacin as examples. Then computation program was programmed using Excel software based on pharmacokinetic parameters combined with pharmacodynamic parameters to design rational dosage regimen. RESULTS: The bactericidal effect of time-dependent antibiotics was chiefly dependent on the time during which the drug blood concentration was higher than minimal inhibitory concentration(MIC).For those antibacterials with short elimination half life(t1/2)in plasma,the best regimen was to give patients the med-icine in a small average divided dose or continuous medication. For those with(t1/2) greater than 12～24 h,single dose admin-istration was advisable. For concentration-dependent antibiotics,the best PK/PD parameters for optimal clinical antibiotic effect were Cmax/ MIC,and which should be administered in single time (daily dose). CONCLUSION: PK/PD parameters -based intermittent intravenous drip dosage regimen of antibiotics designed by means of Excel function is simple,reliable and intuitionistic.

0.05),respectively.CONCLUSION:Intravenous drip combined with oral administration of Amoxicillin/Clavulanate Potassium can replace intravenous dip of Amoxicillin/Clavulanate Potassium bid.For those ?-Lactams drugs with short t1/2,the unreasonable intravenous drip of which qd can be replaced by the intravenous drip combined with N-time oral administration or with N-time intramuscular injection.

Design for Tolerance Trial of Traditional Chinese Medicine for Intravenous Drip in Human Body / 中药新药与临床药理

Intravenous preparations take more risk than oral preparation and externally applied agent.In phaseⅠtoler- ance trial of intravenous preparations of TCM on human subjects,minimum dose and maximum dose should be decided in light of data derived from preclinical pharmacodynamic and toxicological experiments,combined with practical situation in clinic.Dose-ascending coefficient of the should be reasonable.During the application of intravenous preparations of TCM in tolerance trial,clinical monitoring must be done to ensure the safety of subjects.Overall and integrated observa- tional indices should be designed on the basis of the features of preparation types,administration methods,the nature of medicine,etc.,so as to provide full-scale data for safe dose range,concentration of the preparation,dripping veloci- ty and possible adverse reactions,etc.
