OBJECTIVE:To provide reference for further standardizing and perfecting the management of drug unpacking in outpatient pharmacy.METHODS:A total of 6 primary and secondary health institutions (4 community health service centers and 2 secondary hospitals) were selected from 2 districts in Shanghai to conduct a questionnaire survey on the use of their drugs and drug unpacking in outpatient pharmacy.The survey data was analyzed statistically.RESULTS:Totally 6 institution questionnaires and 6 pharmaceutical staff questionnaires were sent out,all were received with recovery of 100％.In 2015,the average number of essential medicines in community health service centers and secondary hospitals were 496.50,542.00,respectively,and the average number of varieties sold were 530.75,1 052.00.In outpatient pharmacy of surveyed community health service center,the number of unpacked drugs was 10-21 which were essential drugs and class A medical insurance drugs,and the consumption sum of unpacked drug ranged 5.56-16.70 ten thousand yuan.In outpatient pharmacy of 2 two secondary hospitals,the number of unpacked drugs were 17 and 23,respectively,most of which were essential drugs and class A medical insurance drugs,and the consumption sum of unpacked drug ranged 13.19 to 158.06 ten thousand yuan.The proportion of unpacked drugs was less than 5％ of the total number of varieties sold,and the proportion of consumption sum of unpacked drugs was less than 1％ of total consumption sum.Estazolam tablets and Alprazolam tablets took up the top 5 in the list of consumption sum of unpacking drugs in 2 types of intervi ewed instiutions.All the surveyed institutions were not equipped with drug dispensing machine in the outpatient pharmacy,still depended on manually unpacking.There were four institutions to regularly arrange the unpacking,unpacking frequency was usually 1 to 3 times a week,supplemented by the need to arrange unpacking,and another two to implement a daily unpacking.There were 5 institutions to develop a drug unpacking mechanism in the institutions,but the relevant system was not perfect.CONCLUSIONS:The enthusiasm of pharmaceutical saff in primary and secondary health institutions in Shanghai to carry out or engage in unpacking work need to be improved,the instructions for unpacked drugs are not available on request,and the way to unpack drugs still needs to explore.

Objective To investigate the optimal interventional therapy for primary hepatocellular carcinoma (HCC) complicated by main portal vein tumor thrombus.Methods Three-stage treatment, i.e. transcatheter arterial chemoembolization (TACE) combined with portal vein stenting and 125I seeds strand implantation, biliary stenting plus 125I seeds strand implantation and endoscopic variceal ligation, was carried out in one patient with primary HCC complicated by main portal vein tumor thrombus. The clinical results were analyzed combined with a review of the relevant literature in order to compare the efficacies of various interventional therapies employed in clinical practice nowadays. Results The sequential therapies of the three-stage treatment program were successfully accomplished. The patient was followed up for over five years and lived well when the report was made. Conclusion At present, TACE combined with portal vein stenting and implantation of 125I seeds strand is the optimal treatment for primary HCC associated with portal vein tumor thrombus.

Objective To study the expressions of programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) in liver injury of acute liver failure (ALF) in rats and the role of PD-1/ PD-L1 in liver inflammatory injury. Methods SD rats were divided into two groups: 6 in normal group and 30 in ALF model group. The ALF models in rats were induced by D-galactosamine (D-Gal). The sera and hepatic tissue samples were collected at 12, 24, 48, 72 and 120 hours after D-Gal injection. Expressions of PD-1 mRNA and PD-L1 mRNA in hepatic tissue samples were detected by reverse transcription-polymerase chain reaction (RT-PCR). Comparison of measurement data between groups was done by t test. Correlation test was performed using Pearson linear correlation analysis. Results The levels of alanine animotransferase (ALT) and aspartate animotransferase (AST) at 12 h of D-Gal injection were (217. 3±33. 7) U/L and (397. 2± 101.3) U/L, respectively,which were both significantly higher than those in normal group [(30. 5 ±3. 1) U/L and (78. 6±4.2) U/L, respectively; t=-8. 921 and -6. 121, respectively; both P＜0.01] and peaked at 48 h.The expression of PD-1 mRNA in model group at 12 h (0. 385±0. 074) was significantly higher than that in normal group (0. 097±0.009) (t= -7. 725, P＜0.01) , and peaked at 48 h (0. 927±0. 132),then decreased obviously at 72 h. The expression of PD-L1 mRNA in the liver tissue of normal rats was very little, while that in model group was increased gradually over time, then peaked at 48 h (0. 593±0. 105; t =- 10. 076, P＜0. 01). The expressions of PD-1 and PD-L1 were positively correlated with ALT level (r=0. 807 and 0. 792, respectively; both P＜0. 01). Conclusion The expressions of PD-1/PD-L1 may play an important role in liver inflammatory injury in rat model of acute liver failure.

Objective:To improve the quality and efficiency of pharmaceutical care of clinical pharmacists by standardizing phar-maceutical care process using tracking table design for clinical drug therapy. Methods: The experience and skills of pharmaceutical care performed by clinical pharmacists in endocrinology department were summarized and the tracking table for clinical drug therapy was designed, which could provide information for patients clearly and concisely, and make the process of pharmaceutical care more system-atical. Results:After using the tracking table, clinical pharmacists improved work efficiency significantly. In addition, the average hospitalization, average hospitalization expenses and drug proportion significantly reduced resulting in higher satisfaction of patients. Conclusion:The standardized pharmaceutical care process performed by clinical pharmacists in endocrinology department makes phar-maceutical care more specific, comprehensive and convenient.

Objective:To evaluate the safety of discontinuing nucleoside/nucleoside analogue (NAs) therapy in patients with compensated hepatitis B cirrhosis after HBsAg negative conversion.Methods:A total of 3 783 patients with hepatitis B cirrhosis in compensated stage were treated with NAs at Taizhou Hospital, Taizhou Municipal Hospital and Taizhou Enze Hospital from January 2008 to December 2020. The clinical data and laboratory tests results of 85 patients with HBsAg negative conversion were retrospectively analyzed, including 36 cases discontinued the drug, and 49 continued to use drug. Chi-square test and rank-sum test were used for data analysis.Results:During the 24 and 48 months of follow-up, the ALT levels were within the normal range in both groups. There were no significant differences in positive rates of anti-HBs and HBeAg ( χ2=0.75, 0.39 and 0.90, P=0.78 0.84 and 0.34; χ2=0.40, 0.00 and 0.00, P=0.84, 1.00 and 1.00) between two groups. After 48 months of follow-up, 2 cases of primary liver cancer occurred in the discontinuation group and no primary liver cancer occurred in the continuation group ( χ2=0.89, P=0.34). Throughout the follow-up, HBsAg remained negative and HBV DNA load was below the lower limit of detection in both groups. Conclusions:Discontinuation of NAs can be considered after the HBsAg negative conversion in patients with compensated hepatitis B cirrhosis.

Protein ubiquitination is widely observed in cells and is a modification after protein translation. Hepatitis B virus (HBV) and ubiquitination of related proteins have attracted more and more attention. This article reviews HBV and the ubiquitination of related proteins, so as to provide a reference for further research on the regulation of HBV replication and the ubiquitination of related proteins, as well as new ideas and methods for curing chronic HBV infection.

OBJECTIVE: To explore the application value of MAR algorithm in metal artifact removal of CT simulator. METHODS: CT phantom with titanium plate was scanned using conventional algorithms and MAR algorithms, respectively. Artifact index(AI), contrast-to-noise ratio(CNR) and AI values at different slices were used to analyze the artifact images. RESULTS: In artifact index, MAR algorithm (10.28±2.60) is significantly lower than conventional algorithm (20.65±5.04); In contrast-to-noise ratio index, MAR algorithm (7.81±1.12) is better than conventional algorithm (5.61±1.36). The above indicators were statistically significant in both algorithms (P<0.01). In the slices affected by metal artifacts, the artifact index decreased by 21.72%~88.40% after the MAR algorithm. CONCLUSIONS MAR algorithm can significantly reduce the metal artifacts and improve the clinical value of CT data.
