OBJECTIVE:To summarize the key issues such as the drug waste and the phone calls affecting the working efficiency in pharmacy intravenous admixture service(PIVAS)and to put forward countermeasures so as to improve the working quality there.METHODS:The records about the drug waste in PIVAS and the phone calls that affected the working efficiency from clinical departments were analyzed statistically.RESULTS:Dispensing error and drug return were the main factors accountable for the drug waste in PIVAS.The proportion of phone calls from clinical departments demanding drug bills and drug dispensing was the highest,which greatly affected the working efficiency in PIVAS.CONCLUSIONS:The clinical staff should be informed not to make the unnecessary calls to PIVAS so as to improve the working quality in PIVAS.

Endotoxin,which is also called lipopolysaccharide (LPS),is a unique element of Gram-negative bacteria.Liver is the main site for removing bacteria and endotoxin.Meanwhile,it is also the most vulnerable organ.Liver injury initially occurs in the hepatic sinu-soids.This article mainly introduces the impact of LPS on Kupffer cells,hepatic sinusoidal endothelial cells,oxidant/antioxidant balance in the hepatic sinusoids,and liver blood flow.It is believed that the function of hepatic sinusoids in LPS-induced liver injury should not be ig-nored,and the hepatic sinusoids would play an important role in the prevention and treatment of LPS-induced liver injury.

OBJECTIVE: To analyze the drug return in our hospital and to put forward countermeasures.METHODS: The drug return in our hospital from 2004 to 2006 was analyzed retrospectively in respect of the amount of money,drug variety and causes.RESULTS: The amount of money of returned drugs increased rapidly in 2005 than the previous year,but decreased in 2006.The major varieties were injectable drugs,followed by anti-infective drugs.Doctors' modification of medical orders was the main reason accountable for drug return.CONCLUSION: It is suggested that effective measures be taken in hospital to strengthen publicizing and management on the rational drug use,standardize procedure of drug return,and improve hospital computer system etc.

Objective To investigate the effect of dexamethasone on the expression of APQ-4 and cytokines in the hematoma and brain tissue of ICH rats. Methods The treatment group was treated with injection of 1mg/kg and dexamethasone, and the model group and the sham operation group were injected with the same amount of normal saline. Results The model group APQ-4, TNF- positive cells. The proportion of second, third, the highest in the 7d after the operation, the sham operation group was the lowest (P<0.05). Conclusion Dexamethasone is beneficial to reduce the APQ-4 expression in brain tissue of rats in ICH, while reducing the expression of TNF- alpha.

Objective To evaluate the value of 3-dimensional conformal radiotherapy combined with Hydroxycamptothecin(HCPT) in the treatment of local advanced non-small cell lung cancer.Methods A total of 95 cases were enrolled and randomly assigned to treatment group and control group.The treatment group was treated with 3-dimensional conformal radiotherapy(3DCRT) combined with HCPT.The control group was treated with 3DCRT only.Results Response rate(CR+PR) is respectively 73.4 % and 62 %.The response rate of treatment group is higher than that of control group(P

Objective To investigate the therapeutic effect,safety and its prognostic factors of capecitabine as maintenance treatment agent for prolonging the PFS of patients with recurrent and metastatic breast cancer after they received combination chemotherapy.Methods From January 2011 to June 2013,38 cases with recurrent and metastatic breast cancer were collected in the department of medical oncology of the First Hospital of Lanzhou University.All the 38 patients received NX scheme (vinorelbine combined capecitabine chemotherapy),and some patients among of them had stabile disease after chemotherapy and were administered X scheme (capecitabine,twice a day,2 000 mg/m2 daily,withdrawal for 7 days after a consecutive intake of 14 days,21 days as a cycle,at least 2 cycles) until disease progressed or toxicity could not be tolerated.Adverse reactions and PFS were observed and recorded.Single factor chi square test and multivariate COX proportion hazard model were used to evaluate the relationships between clinic features and RR,PFS.Results The overall response rate (CR + PR) was 55.26％ (21/38),clinical benefit patients rate (CR + PR + SD) was 84.2％ (32/38),with 4 patients of CR (4/32),17 patients of PR,11 patients of SD,6 patients of PD.Thirty-two no progressived patients were administered capecitabine until PD.The median PFS was 10.0 months.Stratification analysis showed that patients whose Karnofsky (KPS) ≥80 had an average PFS of 14.1 months,while an average PFS of 6.8 months for patients whose KPS ＜ 80,with a statistical significance (x2 =6.251,P =0.000).Cox proportion hazard model also showed that age (RR =3.561,95％ CI:1.372-5.216,.x2 =4.025,P =0.031),menopausal status (RR =1.895,95 ％ CI:1.124-4.452,x2 =5.725,P =0.048),KPS score (RR =4.553,95％ CI:1.131-7.703,x2 =11.205,P =0.005),the number of metastasis (RR =5.781,95％ CI:2.321 ～11.243,x2 =3.925,P =0.011) were important prognostic factors for the patients with breast cancer.Major treatment-related adverse reaction was grade Ⅰ-Ⅱ hand-foot syndrome.One patient discontinued treatment because of grade Ⅲ hand-foot syndrome.Conclusion Capecitabine as maintenance treatment can significantly prolong the PFS of patients with recurrent and metastatic breast cancers at remission or stable stage after combination chemotherapy with a better tolerance.Age of patients,menopausal status,KPS score,the number of metastasis are the prognostic factors for the efficacy of NX-X regimen.

Objective:To investigate the characteristics of urinary stones composition in children and the differences in their distribution among different sexes and age groups.Methods:The clinical data of 592 children with urinary stones who underwent stone composition analysis using infrared spectroscopy at Hunan Children's Hospital from October 2015 to October 2019 were retrospectively analyzed. There were 430 males and 162 females.The median age was 4.0 (0.3 to 18.0) years old. The stone composition and the differences in its distribution in different sex and age groups were analyzed.Results:A total of 643 urinary stones were analyzed in 592 cases, with 419 (65.2%) single-component stones and 224 (34.8%) mixed-component stones. The main stone components were calcium oxalate in 361 cases (56.1%), ammonium hydrogen urate in 130 cases (20.0%), cystine in 56 cases (8.7%), calcium phosphate in 33 cases (5.1%), uric acids in 33 cases (5.1%), magnesium ammonium phosphate in 25 cases (3.9%), and xanthine in 5 cases (0.8%). The percentage of calcium oxalate stones was higher in women than in men [65.6% (118/180) vs. 52.5% (243/463), P<0.05]. The proportion of upper urinary tract stones was higher in girl than in boy[93.4%(168/180) vs. 73.2%(339/463), P<0.05]. The differences in the composition ratios of calcium oxalate stones, ammonium hydrogen urate, cystine, and magnesium ammonium phosphate stones in different age groups were statistically significant ( P<0.05), with the highest proportion of calcium oxalate stones (35.6%) at 6 to 10 years of age, ammonium hydrogen urate and cystine stones at 1 to 2 years of age (45.4% and 42.9%), and magnesium ammonium phosphate stones at 3 to 5, 6 to 10, and 11 to 18 years of age, the percentage of urinary stones in children was 24%. Conclusions:The main component of urinary stones in children is calcium oxalate, followed by ammonium hydrogen urate and cystine. Age and gender correlate with the distribution of stone components. Calcium oxalate stones are common in females and in children aged 6 to 10 years, ammonium hydrogen urate and cystine stones are common in children aged 1 to 2 years, and magnesium ammonium phosphate stones are more common in children aged 3 to 5 years, 6 to 10 years, and 11 to 18 years.
