With dwindling number of new antibiotics and inappropriate use of antibiotics, the emergence and spread of antibiotics resistance occurs commonly in healthcare institutions worldwide. In China, antibiotics are commonly overprescribed and misused. This study is to assess the effect of the nationwide special campaign on antibiotic stewardship program (ASP) at specialized hospitals in China by investigating prescription information from 2011 to 2012. Data on the hospital consumption and prescription of systemic antibiotics were obtained from four specialized hospitals, including maternity, children's, stomatological and cancer hospitals. Systematic random sampling was used to select outpatient prescriptions and inpatient cases. A total of 105 specialized hospitals in 2011 and 121 specialized hospitals in 2012 were analysed. The defined daily doses (DDDs) per 100 inpatient days, the percentage of antibiotic use in outpatient prescriptions, and the percentage of antibiotic use in inpatient cases were used as measurements of antibiotic use. The overall antibiotic use density in the selected hospitals decreased between 2011 and 2012 from 39.37 to 26.54 DDD/100 inpatient days (P<0.001). The percentage of antibiotic use in outpatient prescriptions (range: 24.12%-18.71%, P=0.109) and inpatient cases (64.85%-60.10%, P=0.006) also decreased within the two years. Significant changes were observed among regions and different hospitals within the two years. And antibiotic consumption was correlated with the type and size of specialized hospital in 2012, but not with the regions. This analysis of antibiotic consumption of specialized hospitals allows relevant comparisons for benchmarking and shows that national ASP has improved antibiotic rational use in China. The data will assist policymakers in formulating effective strategies to decrease antibiotic overuse and identify areas that require further work.

OBJECTIVETo investigate the effects of serum containing Chinese medicine (CM) Sanpi Pingwei (, SPPW) formula on the proliferation and apoptosis of human SGC-7901 cells and the possible mechanism.
METHODSSerum containing CM SPPW formula (SPPW serum) was prepared by a serum pharmacology method. Human SGC-7901 cells were incubated with SPPW serum at three different concentrations and with the anticancer drug 5-fluorouracil (5-FU), respectively. Cell proliferation was assessed by MTT assay, and cell apoptosis was detected by flow cytometry assay. Real-time quantitative polymerase chain reaction (RT-PCR) and Western blot assay were employed to confirm the expressions of Bcl-2, Bax and p53 in SGC-7901 cells at mRNA and protein levels, respectively.
RESULTSSPPW serum suppressed the proliferation of SGC-7901 cells in a time- and dose-dependent manner. The colony forming rate of negative control was 48.2%, while those in the three SPPW serum groups and the 5-FU group decreased significantly (P<0.01). The number of colony forming units in the SPPW high dosage group was significantly smaller than that in the 5-FU group (P<0.01). MTT assay showed that SPPW serum restrained the proliferation of SGC-7901 cells, and the inhibition rate increased significantly in a dose-dependent manner. Annexin V/PI Assay suggested that SPPW serum induced the apoptosis of SGC-7901 cells significantly. RT-PCR and western blot assay indicated that SPPW serum upregulated the protein and mRNA expression levels of Bax and p53 in SGC-7901 cells, but downregulated the protein and mRNA expressions of Bcl-2.
CONCLUSIONSSPPW formula inhibits the proliferation of SGC-7901 cells in vitro and induces the cell apoptosis. It plays an anticancer role by regulating the expressions of Bax, p53 and Bcl-2 in SGC-7901 cells.

Objective:To analyze the clinical features and prognosis of lymphoma patients with monoclonal immunoglobulin (McIg).Methods:The data of 14 patients who were pathologically diagnosed as lymphoma and with McIg in the First Affiliated Hospital of Fujian Medical University from January 2014 to January 2019 were retrospective analyzed. At the same time, 40 lymphoma patients without McIg were sellected as controls. The patients'age, gender, international prognostic index (IPI) score, B symptoms, tumor cell source and Ki-67 index were analyzed by prognostic single factor analysis. Kaplan-Meier method was used for survival analysis, and the overall survival (OS) and progression-free survival (PFS) were compared between the two groups.Results:Among 14 lymphoma patients with McIg, 6 were males and 8 were females. The median age of onset was 63 years (42-78 years). There were 13 cases of clinical stage Ⅲ-Ⅳ, and 12 cases of extranodal disease. The most common type was IgM-κ. The results of univariate analysis showed that IPI score≥3 points and elevated D-dimer level were related to poor prognosis (both P < 0.05). At the end of follow-up, the median OS time of lymphoma patients with McIg had not reached, the 2-year OS rate was 64.3%, and the median PFS time was 16 months; the median OS time of lymphoma patients without McIg had not reached, the 2-year OS rate was 90.8%, and the median PFS time was 37 months; the difference of OS between the two groups was statistically significant ( P = 0.040). Conclusions:Most lymphoma patients with McIg have extranodal involvement, the clinical stage is more inclined to stage Ⅲ-Ⅳ, IPI score ≥3 points and elevated D-dimer level are poor prognostic factors. The secretion of McIg is an important factor for the poor prognosis of patients with lymphoma.

FMS-like tyrosine kinase 3 (FLT3) is a receptor of tyrosine kinase that is constitutively activated in most of acute myeloid leukemia patients and seems to give an adverse prognosis. In order to explore the silencing effect of FLT3 targeted short hairpin RNA (FLT3-shRNA) on acute leukaemia cell line THP-1, three FLT3-shRNAs (shRNA1, shRNA2, shRNA3) were designed and synthesized by transcription system in vitro and then transfected into THP-1 cells. FLT3 mRNA was analyzed by semi-quantitative RT-PCR, FLT3 protein was detected by Flow cytometry and immunofluorescence. The results indicated that FLT3 expression was downregulated by shRNA1 and shRNA3, and shRNA1 showed stronger inhibitory effect. At 48 hours following transfection, the inhibitory rate of 25 nmol/L shRNA1 was 72.95 +/- 2.07%, lasting 72 hours. The 5 nmol/L and more concentration of FLT3 shRNA1 could downregulate FLT3 mRNA level, which displayed a quantity-effect relation; the inhibitory rate of 15 nmol/L shRNA1 was 67.53 +/- 0.66%. FLT3 protein was located on THP-1 cell membrance, its expression was downregulated obviously by shRNA1, at 72 hours following transfection the inhibitory rate of shRNA1 was 79.67 +/- 0.66%. shRNA1 showed the best inhibitory effect on FLT3 protein, the optimal time of which was 72 hours with an inhibitory rate of 79.67%. It is concluded that FLT3-shRNA1 shows a desireable FLT3-targeted inhibitory effect, which can be used for further investigation of FLT3 mechanism or FLT3 targeting treatment.

OBJECTIVETo analyze hepatotoxicity of Polygonum multiflorum and clinical character- istics of drug-induced liver injury (DILI) caused by Polygonum multiflorum and its preparations.
METHODSA retrospective study was performed in 158 patients treated at 302 Military Hospital between January 2009 and January 2014. All of them had used Polygonum multiflorum and its preparations before the onset of DILI, and their clinical characteristics and prognoses were analyzed.
RESULTSOf the 158 DILI patients who used Polygonum multiflorum or its preparations, 92 (58.2%) combined with Western medicine or Chinese herbal preparations without Polygonum multiflorum; 66 patients (41.8%) used Polygonum mult florum and its preparations alone. In 66 DILI patients induced by Polygonum multiflorum or its preparations alone, 51 cases (77.3%) were induced by Polygonum multiflorum compounds and 22.7% by single Po- lygonum multiflorum; 4 cases (6.1%) were caused by crude Polygonum multiflorum and 62 (93.9%) by processed Polygonum multiflorum and its preparations. Clinical injury patterns were hepatocellular 92.4% (61 cases), cholestatic 1.5% (1 case), and mixed 6.1% (4 cases). Pathological examination was per- formed by liver biopsy in 32 cases (48.15%), manifested as hepatocellular degeneration and necrosis, fibroplasia, Kupffer cells with pigment granule, and a large number of eosinophil infiltration, were ob- served. Four patients were developed into liver failure, 4 into cirrhosis, and 1 died.
CONCLUSIONPolygo- num multiflorum and its preparations could induce DILI, but clinical diagnosis of Polygonum multiflorum induced hepatotoxicity should be cautious.

OBJECTIVETo study the anatomy of the small intestine,and investigate the optimal selection of donors,recipients,and their small intestine vessels in piglet small intestine transplantation.
METHODSThe weight and length of 30 piglets were measured. Angiography and pigments perfusion were used to observe the main vessels of the small intestine,and the length of the small intestine,and the external diameter of the main vessels of the small intestine were measured in vivo and ex vivo.
RESULTSThe length of the small intestine was 11.5 times as long as the body length, and its weight accounted for 2.3% of the body weight. The outer diameters of abdominal aorta (AT), mesenteric anterior artery (MAA) and its 5(th)-6(th) branches in vivo and ex vitro were 4.3/4.6mm, 2.5/2.7mm and 1.9/2.2mm respectively. The total number of MAA's branches was 6-8 in general and its 5(th)-6(th) branches were the longest [(20.0 +/- 7.0) mm, (22.0 +/- 8.2) mm]. The outer diameter of mesenterial anterior vein (MAV) was 1-2 mm wider than that of MAA.
CONCLUSIONSAT, MAA and its 5(th)-6(th) branches are the preferable vessels for small intestine transplantation. In segmental small intestine transplantation, the length of the small intestine and body weight can be used to primarily select the suitable animals.

Two giant pandas (Ailuropoda melanoleuca) died of unknown causes in a Chinese zoo. The clinical disease profile suggested that the pandas may have suffered a viral infection. Therefore, a series of detection including virus isolation, electron microscopy, cytobiological assay, serum neutralization and RT-PCR were used to identify the virus. It was determined that the isolated virus was a canine coronavirus (CCV), on the basis of coronavirus, neutralization by canine anti-CCV serum, and 84.3% to 100% amino acid sequence similarity with CCV. The results suggest that the affected pandas had been infected with CCV.

This study was aimed to investigate the mechanism of indoleamine 2, 3-dioxygenase (IDO) activity in acute myeloid leukemia cells contributing to tumor immune escape. Myeloid leukemia cells were isolated from bone marrow of 23 patients with acute myeloid leukemia (AML) and IDO expression was detected by immunochemistry and RT-PCR methods. Then mixed lymphocyte reaction (MLR) of one way was carried out, leukemia cells were used as stimulating cells and T-lymphocytes were used as reactive cells in culture with or without 1-MT. T-lymphocyte proliferation rate was determined by MTT assay and IDO activity in supernatant of MLR was detected by high-performance liquid chromatography (HPLC). The results showed that IDO expression was found in 17 out of 23 cases of acute myeloid leukemia cells; IDO enzyme activity in leukemia cells inhibited T-lymphocyte proliferation in MLR cultures. It is concluded that IDO activity expressing in leukemia cells can suppress T-lymphocyte proliferation responses, which may be contributing to tumor immune escape.
