Objective To discuss the role of therapeutic drug monitoring (TDM) in pharmaceutical care by successful intervention of severe drug-drug interaction in 3 patients with hematological disease treated with voriconazole and rifampin.Methods Three patients with hematological disease were monitored for the plasma concentration of voriconazole before,during,and after the concomitant use of rifampin.The severity of this drug interaction was revealed,risks for developing invasive fungal infection and tuberculosis dissemination after chemotherapy were evaluated based on the TDM results,and alternative regimens were recommended.Results Voriconazole plasma concentration was normal at baseline but significantly depressed after combination with rifampin in all 3 cases.Concomnitant use of rifampin leads to a rapid decline in plasma concentration of voriconazole in 2-3 days,and withdraw of this enzyme induction effect takes 8-10 days after discontinuation of rifampin.Conclusion TDM is a helpful tool for providing pharmaceutical care,it helps to objectively visualize the degree of clinically important drug-drug interactions.Clinical evidence together with TDM results suggests high risk for developing invasive fungal infection and tuberculosis dissemination in hematology patients while using this combination therapy.Discontinuation of rifampin was suggested and accepted.For these patients,combination of voriconazole and rifampin should be avoided.

Objective To observe the clinical efficacy of Huoxue Bitong Plaster on lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome. Methods Totally 120 patients were randomly divided into treatment group (60 cases) and control group (60 cases). Huoxue Bitong Plaster was applied externally in the treatment group, while Goupigao Plaster was used externally in the control group, once a day, for two weeks. The clinical efficacy was evaluated by observing TCM symptom scores, VAS, Oswestry dability index (ODI), and onset time in both groups before and after treatment. Results The total effective rate was 86.67%(52/60) in treatment group, and 85.00% (51/60) in the control group, with no statistical significance (P>0.05). TCM symptom scores of both groups decreased after treatment (P<0.05). For the effect of relieving back pain and morning stiffness, the treatment group was superior to control group (P<0.05). For the effect of relieving waist heaviness, the control group was better than the treatment group (P<0.05). Besides, VAS and ODI of the treatment group were lower than the control group after treatment (P<0.05). The onset time of lightening back pain, morning stiffness in the treatment group was quicker than control group (P<0.05). For waist heaviness, the onset time in control group was quicker than treatment group (P<0.05). Conclusion Huoxue Bitong Plaster has good efficacy for lumbar osteoarthritis with blood stasis and cold-dampness blocking collaterals syndrome.

Objective To study the predictive value of umbilical cord blood regulatory T cells (Treg) for bronchopulmonary dysplasia (BPD) in preterm infants. Method From June 2017 to December 2018, premature infants with gestational age less than 32 weeks admitted to NICU of our hospiatal were prospectively selected. The umbilical cord blood was collected at birth to examine the Treg amount. The infants were assigned into BPD group and non-BPD group according to the diagnosis at discharge. The differences of Treg amount between the two groups and different degrees of BPD were analysed. Result A total of 124 premature infants (GA<32 weeks) were admitted, including 41 cases in BPD group (mild, n=18;moderate, n=14; severe, n=9) and 83 cases in the non-BPD group. The BPD group had GA of (29.6 ± 1.1) weeks and birth weight (BW) of (1128 ± 135) g. The non-BPD group had GA of (29.8 ± 1.1) weeks and BW of (1316 ± 180) g. The birth weight, 1min and 5min Apgar scores in BPD group were lower than the non-BPD group (P<0.001). The BPD group had higher incidence of respiratory distress syndrome, longer duration of mechanical ventilation (MV) and oxygen inhalation(P<0.001) than the non-BPD group. The MV duration and oxygen inhalation duration in the severe BPD group were significantly longer than the moderate and mild BPD groups, and the duration in the moderate group was longer than the mild group (P<0.001). The number of Treg in cord blood in the BPD group [(1.43 ± 0.06) × 105 cells/ml] was significantly lower than the non-BPD group [(2.57 ± 0.09) × 105 cells/ml], and the difference was statistically significant (P<0.001). Multivariate Logistic regression analysis showed that a significant decrease in the number of Treg was a risk factor for BPD in premature infants (OR=0.000, 95%CI 0.000 ~ 0.012, P=0.009). The number of Treg in umbilical cord blood was negatively correlated with the severity of BPD. The area under the ROC curve showed that the cut-off value was 1.95 × 105 cells/ml, with Youden index 0.613, sensitivity 85.4% and specificity 75.9%. Conclusion The number of cord blood Treg cells may be a useful biomarker for predicting BPD in premature infants.

Objective:
To investigate the current basic situation of the staff of ultrasound departments in Shanghai′s medical institutions, for providing references in making management policy of these professionals.
Methods:
Questionnaire surveys on human resource and service ability were made to all the ultrasound departments of medical institutions in Shanghai in December 2013 and November 2018 respectively. Data of the two surveys were compared and analyzed, and were descriptively analyzed by mean and percentage.
Results:
The number of ultrasound professionals per 10 000 people in Shanghai was 1.04 in 2018. Tertiary hospitals had advantages in the number of the professionals, and the proportion of professional qualification, age, education background and professional title of the professionals. Compared to those data in 2013, the number of ultrasound professionals had increased 31.8% in 2018. The proportion of medical practitioners with medical imaging specialty was 95.6%(2 063/2 158), and had increased by 4.7 percent. The medical services workload of ultrasound was 19.82 million person-time, and had increased 45.8%.
Conclusions
Development of ultrasound departments was rapid, but the development of professionals was unbalanced with the development of medical services. It is suggested to strengthen training of ultrasound professionals and improve the system of hierarchical medical system.
