The study aimed at investigation the effect of the transgenic biocontrol bacteria 308R(pCPP430) on the tomato rhizosphere bacterial communities. Strain 308R (Pantoea agglomerans), an adnascent bacterium isolated from tomato, was a biocontrol bacterium. The recombinant cosmid pCPP430 contained the hrp gene cluster of Erwinia amylovora was transformed into 308R Strain. Transgenic biocontrol bacterium 308R(pCPP430) produced Harpin protein which induce hypersensitive response and disease resistance in plants and, surprisingly, increase plant growth. Two complementary methods, sole-carbon-source utilization tests (SCSU) and ERIC-PCR, were used to compare the characterization of bacterial communities from three groups of tomato roots dipped in sterilized water, 308R suspended liquid and 308R(pCPP430) suspended liquid. The cluster analysis and principal components analysis of the number of colonies from SCSU indicated consistent differences in the rhizosphere of each group. Cluster analysis of SCSU data showed that there were consistent differences in the rhizosphere of each group. The rhizosphere bacteria communities of root dipped with 308R(pCPP 430) and 308R have a relative good replication, but the differences of corresponding replicates in dipped with distilled water was increased by degrees. Cluster analysis of ERIC-PCR fingerprints revealed that most of results (eight in ten) have overlaps between roots dipped in water and those dipped in 308R liquid. The methods used in this study may prove a useful approach for the comparison of bacterial communities.

Objective: To investigate the factors affecting drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019, so as to provide insights into the prevention of drug-induced liver injury. Methods: Demographic features, presence of drug-induced liver injury, and disease history prior to anti-tuberculosis therapy were captured from patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019 through the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System and Ningbo Regional Diagnosis and Treatment Information Platform. Factors affecting drug-induced liver injury was identified using the multivariable logistic regression analysis. Results: A total of 9 397 patients with pulmonary tuberculosis were enrolled, among whom 66.43% ( 6 242 case ) were male, 65.89% ( 6 192 cases ) were at ages of <60 years, and 92.35% ( 8 678 cases ) were treatment-naïve. There were 1 425 patients with drug-induced liver injury (15.16% incidence), including 729 cases with grade 1 (51.16%), 24 cases with grade 2 (1.68%), 7 cases with grade 3 (0.49%), 7 cases with grade 4 ( 0.49% ), and 658 cases with ungraded drug-induced liver injury ( 46.18% ). The median duration between drug administration and development of drug-induced liver injury was 24 ( interquartile range, 44 ) days. Multivariable logistic regression analysis identified treatment-naïve ( OR=1.464, 95%CI: 1.153-1.859 ) and history of liver disease ( OR=2.001, 95%CI: 1.709-2.342) as risk factors for drug-induced liver injury in patients with pulmonary tuberculosis. Conclusion The incidence of drug-induced liver injury was 15.16% among pulmonary tuberculosis patients in Ningbo City from 2015 to 2019. Treatment-naïve and a history of liver disease are associated with drug-induced liver injury among patients with pulmonary tuberculosis.

Four impurities were isolated from raw material of clindamycin phosphate (CP), and their structures have been determined. LC-MS was used to determine the molecular weights of the impurities in the raw material of CP. Reversed-phase preparative HPLC was used to prepare them, and their chemical structures were identified by HR-MS and NMR. The four unknown impurities were determined as clindamycin-B-phosphate (1), clindamycin-2,4-diphosphate (2), 3',6'-dehydro clindamycin phosphate (3), epi-clindamycin phosphate (4). Impurity 1 has been included in BP and EP, while 2, 3 and 4 have not. The impurities 2, 3, 4 are first separated from raw material of CP.

For most of nonlinear systems, control strategy is complicated. The adaptive control methods based on the model identification can effectively improve the control precision and stability. According to the nonlinear and time-changeable characteristics of the wrist movement in the functional electrical stimulation, modeling and identification of wrist movement based on Hammerstein model were implemented. By using M sequence and invert-repeated M sequence as excitation signal, the wrist model is divided into the linear dynamic part and the nonlinear static part. The characteristics of nonlinear part being taken into consideration, an adaptive control method based on time-changeable characteristics of linear part is presented. This method simplifies the control strategy, and it is validated by the simulation experiment of FES.

Objective To explore the causes of per-hospitalization high inpatient expenditure of a tertiary hospital in 2015,by analyzing the influencing factors.Methods We retrospectively studied 1 282 inpatient cases who cost more than 100 000 yuan per case at a tertiary hospital in 2015,analyzing statistically major influencing factors of such expenditure in variance analysis and multiple stepwise regression analysis.Results The average days of stay of these cases were 27.6 days,and the average medical cost of those cases was 149 153 yuan per person.Costs for medicines and material made up a large proportion of medical costs,respectively accounting for 33.38% and 31.98% of the total.The days of stay,prognosis of the patient,complications as well as hospital infection,surgeries,gender of the patients constituted major factors on inpatient medical expenditure.Conclusions Reducing the average days of stay,guiding reasonable applications of drugs and medical materials,strengthening management on operations and controlling excessive medical services are effective approaches to reducing excessive growth of medical costs.

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.

To evaluate the differences of Ophiopogonjaponicus from different cultivations, the metabolomics based method was conducted to compare the effects of Hangmaidong and Chuanmaidong (Chinese name) on plasma endogenous metabolites of normal rats. Data were collected by ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-Q-TOF/MS), and were analyzed by multivariate statistical method, such as Principal Component Analysis and Orthogonal Signal Correction Partial Least Square Discriminant Analysis. Results revealed that the plasma metabolites profiling of low and middle dose group of Chuanmaidong were similar to the control group, but different from the high dose group obviously. Meanwhile the high, middle and low dose groups of Hangmaidong were different from control group notably, and the difference is dose dependent. Lysophosphatidylcholines, the possible endogenous metabolites which contribute to the classification most significantly, are closely related to cardiovascular system diseases. Compared with the group of Chuanmaidong, Hangmaidong has greater impact on the plasma metabolic profiling of normal rats. Hangmaidong and Chuanmaidong showed significant differences pharmacodynamically.
