Traditional Chinese Drug Research & Clinical Pharmacology 1993;0(02):-
Objective To observe the attenuated effect of Kanglaite Injecti on (KI) combined with chemotherapeutic drugs on transplanted human lung cancer A54 9 in nude mice. Methods Ninety- six nude mice were transplanted subcutaneousl y with human lung cancer A549; 7 days later, the mice were randomized into 16 gr oups(n=6) and were given antitumor drugs according the regimen. Other 12 normal mice were used as controls. KI groups were given KI 1.25, 2.5 and 5.0 g/kg respe ctively and were administered (iv) continuously for 10 times on 7th day of trans plantation; cisplatin (DDP, 1.5 mg/mg or 3 mg/kg) and Gemzar (30 mg/kg or 60 mg/ kg) were given one dose by intraperitoneal injection on 10th day of transplantat ion; Gemzar was given again 4h after medication of DDP. Taxotere (25 mg/kg) was given one dose by intraperitoneal injection on 7th day of transplantation. The m ice were killed to examine the body weight, tumor weight and tumor- inhibiting rate. Results KI 1.25, 2.5 and 5.0 g/kg respectively combined with DDP 3mg/kg and Gemzar 60 mg/kg had a better inhibitory effect on the growth of human lung c ancer A549 than KI, DDP and Gemzar alone. KI in three doses respectively combine d with DDP 1.5 mg/kg and Gemzar 30 mg/kg not only had a better inhibitory effect than those of KI, DDP and Gemzar alone, but also promoted the antitumor actions . The tumor- inhibitory rate of KI in three doses respectively combined with Ta xotere (25 mg/kg) was higher than KI and Taxotere alone. Conclusion KI combine d with DDP and Gemzar or with Taxotere can shorten the tumor mass and has tumor - inhibitory and attenuated effect.

Objective To observe the preventive and therapeutic effect of Ka ng laite Injection (KI) on acute nephrotoxicity in rats induced by cisplatin (DDP) and gemzar.Methods Forty SD rats, male and female in a half, were randomized in to normal control group, KI group, DDP+ Gemzar group and KI+ DDP+ Gemzar gro up, 5 male and 5 female in each group. The KI+ DDP+ Gemzar group were given K I 10 mL/kg first,DDP injection 6 mg/kg 2 hours later and Gemzar injection 90 mg/ kg 4 hours later. After treatment, acute nephrotoxicity was observed.Results On e week after treatment, all of the rats survived; the body weight of the male an d female rats in group was similar in KI group and in the normal control group, but lower in DDP+ Gemzar group, in particular the male rats, than that in norma l control group. Body weight in KI+ DDP+ Gemzar group was lower than that in the normal control group but higher than that in DDP+ Gemzar group.The serum le vels of biochemical parameters were similar in KI group and the normal control g roup; serum levels of total protein (TP) and albumin(ALB) were markedly lower bu t those of blood urea nitrogen (BUN) and creatine (CRE) higher in DDP+ Gemzar g roup than those in the normal control group; the above indexes were improved in KI+ DDP+ Gemzar group as compared with those in DDP+ Gemzar group and arrive to the normal level.Conclusion KI has preventive and therapeutic effect on acu te nephrotoxicity in rats induced by DDP and Gemzar.

Chinese Medical Equipment Journal 2017;38(4):74-77
Objective To explore a safe and effective imaging method by the application of 3D contrast-enhanced MR Angiography (3D CE-MRA) with low-or conventional-dose contrast agent to the examination of lower extremity arterial disease.Methods Totally 31 patients suspected with lower extremity arterial stenosis or occlusion underwent 3D CE-MRA examination including one patient had right leg cut due to the disease,of whom,18 ones had conventional-dose contrast agent (38 ml) injected in 1.5T MR machine and 13 ones had low-dose agent (15 ml) injected in 3.0T MR machine.Quality evaluation was carried out for the images by different doses of agents.Results All the patients had no agent allergy occurred,and one patient had left tibia-fibula motion artifact due to involuntary movement.3.0T MR machine with low-dose agent behaved better than 1.ST MR machine with conventional-dose agent in leg imaging,while there were no significant differences between the quality of the images except that of popliteal artery (P>0.05).Conclusion 3D CE-MRA is an effective and safe method in detecting lower extremity artery disease,and 3.0T MR machine with low-dose agent lays a foundation for clinical diagnosis and treatment.

Objective To observed the analgesia and adverse reactions of continuous patients-controlled in-terscalene analgesia with patient-controlled intravenous analgesia for the shoulder arthroscopic surgery.Methods 40 patients with ASA Ⅰ ~Ⅱ anesthesia in general anesthesia for the shoulder arthroscopic surgery were selected and randomly divided into the two groups,20 cases in each group.They were continuous patients-controlled interscalene analgesia(PCNA)and patient-controlled intravenous analgesia (PCA).PCNA with 0.2% ropivacaine +saline to 100mL,background parameters 4ml/h,a single dose of 0.5mL,lock 20min.24 hours after dosing.PCA with fentanyl lmg +tropisetron 5mg +saline to 100mL,background parameters 2mL/h,a single dose of 3.5mL,lock 20min.Record the VAS score 6h,12h,24h,48h after surgery,and adverse side effects of postoperative dizziness,nausea,vomiting and itchy skin.And the patient's analgesic satisfaction survey 48h after surgery.Results PCNA after surgery 6h,12h, 24h,48h in VAS score was significantly lower than the PCA(P <0.05).PCNA were dizziness,nausea,vomiting and the incidence is lower than the PCA,the difference was statistically significant(P <0.05).The PCNA of patients sat-isfaction was 100%,the PCA of patients satisfaction is 75%,the difference was statistically significant(P <0.05). Conclusion In the postoperative analgesia of shoulder arthroscopic surgery,the analgesic effect and patient satisfac-tion of continuous patients-controlled interscalene analgesia are better than patient-controlled intravenous analgesia. And the dizziness,nausea,vomiting is lower.

Objective To investigate the changes of antibiotic resistance and its correlations with antibiotics use density (AUD) in intensive care unit (ICU) after implementation of antimicrobial stewardship. Methods Data on AUDs and synchronous antibiotic resistance in ICU of the Affiliated Hospital of Taishan Medical University during 2010 and 2014 were retrospectively reviewed.Autoregressive integrated moving average ( ARIMA) model was used to identify the correlation between AUDs and antibiotic resistance.Results The total AUD which stood at 163.46 DDDs· 100 person-1 · d-1 in the year 2010 decreased to 68.20 DDDs · 100 person-1 · d-1 in 2014, and the most significant decreases were found in quinolones, imidazole, carbapenems, aminoglycosides, other beta lactam and macrolides. Synchronously, a wide range of improvements in antibiotic resistance of major pathogens were also observed from 2010 to 2014, and the improvements were positively correlated with the decrease of AUDs.However, antibiotic resistance in 2014 was not significantly improved compared with that in 2013. The rate of ciprofloxacin resistance in Pseudomonas aeruginosa and the resistant rates of amikacin, imipenem, and meropenem in Acinetobacter baumannii even increased in 2014.Conclusions With the implementation of antimicrobial stewardship, antibiotic consumption in ICU was decreasing, and antibiotic resistance rate in major pathogenic bacteria was decreasing.But the rebound in antibiotic resistance in some types of bacteria was also observed and should be put on enough caution.
