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.

Objective To explore the value of the Accordion severity grading system (ASGS) in predicting short-term outcomes after orthotopic liver transplantation for severe hepatitis by classifying post-surgery complications.Methods The clinical documents of 159 patients were retrospectively analyzed who underwent orthotopic liver transplantation for severe hepatitis between Aug.1,2004 to Sept.1,2014 at our center.Complications were categorized according to the ASGS:grade 1 (mild),grade 2 (moderate),grade 3-5 (severe),and grade 6 (death).Outcome measures included ventilator support time,the length of ICU stay,postoperative recovery time.Spearman rank correlation analysis was used to test the correlation between the different grades with these outcome measures.1-year survival trends of different grade complication groups were demonstrated by Kaplan-Meier method and compared by Log-rank test.Results In total,43 (27.0％) patients had a grade 2 complication;41 (25.8％) grade 3;31 (19.5％) grade 4;9 (5.7％) grade 5;and 35 (22.0％) grade 6.There was no grade 1 patient.There was a significant correlation between the complication grades and the ventilator support time,the length of ICU stay and postoperative inpatient time (P＜0.01).With the increase of the complication grades,the outcome measures were even worse.Severe grade complication group had a longer ventilator support time,the length of ICU stay and postoperative inpatient time than the moderate grade complication group (P＜0.01).There was a significant downward trend in 1-year survival with the increase of the complication grade (P＜0.01).Conclusion The ASGS is helpful to assess risks and predict short-term outcomes after liver transplantation for severe hepatitis.Higher Accordion grades are correlated with even worse short-term outcomes.

Objective:To evaluate the effectiveness of correction of sunken upper eyelid with central orbital fat transposition during upper blepharoplasty.Methods:We performed 58 cases of upper blepharoplasty with sunken upper eyelids during January 2016 and June 2020. The lateral portion of the central orbital fat was dissected and reversed 180 degrees, and then fixed to the medial fat pad. Photographs before and 6 months post-operatively were measured to determine the degree of the upper eyelid depression. The results were compared statistically. At the consultation 6 months postoperatively, the patients were asked to evaluate the results of the operation using the Clients Satisfying Questionnaire, with the grade between 4 (very satisfactory) and 0 (very dissatisfactory).Results:Sunken eyelids were effectively corrected in 41 of the 52 patients, but 11 patients had minimal effect because of the lack of sufficient central fat volume mostly due to the prior blepharoplasty. At 6 months post-operatively, 52 of the 58 patients finished the satisfaction questionnaire. Forty one of the 52 patients were satisfying with the results. The mean score was 3.3+ 0.73. The degree of the upper eyelid depression was (4.9+ 1.1) mm preoperatively and (2.4+ 0.7) mm postoperatively. There was a statistically significant difference ( P<0.05). Conclusions:The central orbital fat transposition is an effective way to correct the sunken upper eyelids during the upper blepharoplasty. The results are satisfactory with full upper eyelids and smooth double eyelids.

Objective:To study the role of indocyanine green(ICG)fluorescence imaging in laparoscopic partial splenectomy (LPS).Methods:The data of 4 patients who underwent ICG fluorescence imaging technology for LPS at Beijing Luhe Hospital Affiliated to Capital Medical University from May 2017 to May 2020 were retrospectively analyzed. There were 3 females and 1 male, aged 46, 41, 27 and 12 years respectively. The extents of spleen preservation were compared between ICG fluorescence imaging with ordinary white light during operation. The residual splenic remnants were tested with fluorescence imaging after splenectomy, which showed fluorescence fading indicating good vascular perfusion.Results:ICG fluorescence imaging was performed on 4 patients. The operation time ranged from 180.0 to 250.0 min, and the intraoperative blood loss ranged from 40.0 to 200.0 ml. The postoperative hospital stay ranged from 4 to 14 days. There were no serious complications. Postoperative histopathology showed: splenic cyst ( n=1), splenic hemangioma ( n=2), and splenic laceration ( n=1). Conclusions:ICG fluorescence imaging technology had a significant role to play in partial splenectomy. This study showed this technique to improve safety of laparoscopic partial splenectomy.

Objective:To investigate the protective effect of Momordica charantia polysaccharide (MCP) on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice and the possible mechanism. Methods:MCP was extracted from Momordica charantia (MC). Fifteen C57BL/6J mice were randomly divided into three groups with five in each group: control group, DSS group and DSS+ MCP group. The body weight and disease activity index (DAI) of the mice were monitored every day. Mouse colon tissues and serum samples were collected. Pathological changes in intestinal tissues and the expression of inflammatory factors, CD4 + T cells, neutrophils and macrophages were analyzed by HE staining, ELISA, RT-qPCR and flow cytometry. Results:MCP alleviated the DSS-induced UC in mice by restoring body weight and stool consistency and reducing bleeding. Moreover, MCP could repair the mucosal barrier function of colon tissues, decreasing inflammatory cell infiltration and lessening the edema in mucosal layer and muscle layer, and therefore protect the damaged intestinal tract of mice. The expression of inflammatory cytokines (TNF-α and IL-1β) and the level of CD4 + T cells were decreased in the colonic tissues of MCP-treated mice. Conclusions:MCP ameliorated DSS-induced UC in mice through inhibiting weight loss, repairing colonic tissue damage, improving immune system disorder and decreasing the expression of inflammatory cytokines. This study provided reference for further study of MCP as a potential dietary intervention in the treatment of UC.

Objective:To investigate the value of brain functional connectivity density (FCD) derived from resting-state functional magnetic resonance imaging (rs-fMRI) in differentially diagnosing 2 subtypes of Parkinson's disease (PD): tremor dominant (TD) and non-tremor dominant (nTD), as well as its correlation with clinical symptom scores.Methods:A retrospective analysis was performed; 45 PD patients (25 with TD and 20 with nTD), admitted to Department of Neurology, Drum Tower Hospital Affiliated to Medical School of Nanjing University were chosen; and 24 middle-aged and elderly volunteers matched in age, gender and years of education at the same time were chosen as normal controls (NCs). The rs-fMRI data were collected and FCD map of the whole brain was computed. The FCD differences in whole brain and brain regions enjoying different FCD were compared among the 3 groups. ROC curve was used to analyze the differential diagnostic efficacy of FCD in brain regions enjoying different FCD in TD and nTD. Correlations of FCD in brain regions enjoying different FCD with disease course, Hoehn-Yahr (H-Y) grading, unified Parkinson's disease rating scale (UPDRS) III scores, tremor scores and non-tremor scores were analyzed by Pearson or Spearman correlation analyses.Results:Brain regions enjoying different FCD among the TD, nTD, and NC groups were the right lingual gyrus, right orbital medial frontal gyrus, right insula, left superior temporal gyrus, left insula, right anterior central gyrus, left posterior central gyrus, right medial and paracingulate gyrus, and left angular gyrus. FCD in the right orbital medial frontal gyrus and left angular gyrus of TD group was significantly higher than that in the nTD group ( P<0.05); while FCD in the right insula, right anterior central gyrus, left posterior central gyrus and right medial and paracingulate gyrus of TD group was significantly lower than that in the nTD group ( P<0.05). Area under the curve of combined application of FCD in brain regions enjoying different FCD in differentially diagnosing TD and nTD was 0.842, with sensitivity and specificity of 80.0%. FCD in the left superior temporal gyrus and left posterior central gyrus was positively correlated with H-Y grading ( P<0.05), while FCD in the left angular gyrus was negatively correlated with H-Y grading ( P<0.05). FCD in the left superior temporal gyrus was positively correlated with UPDRS III scores ( P<0.05). FCD in the right lingual gyrus, right insula, left insula, right anterior central gyrus, left posterior central gyrus, right medial and paracingulate gyrus was negatively correlated with tremor scores ( P<0.05). FCD in the left superior temporal gyrus, right medial and paracingulate gyrus was positively correlated with non-tremor scores ( P<0.05), whereas that in the left angular gyrus was negatively correlated with non-tremor scores ( P<0.05). Conclusion:Abnormalities in FCD exist in certain brain regions of PD patients, with disparities between TD and nTD. Combined application of FCD in brain regions enjoying different FCD can effectively differentiate TD and nTD, and this FCD is also partially correlated with the symptom scores of PD patients.

Objective:To analyze hepatic hemodynamic parameters detected by Doppler ultrasound (DU) of uncomplicated children who underwent left lateral segment(LLS) LDLT (LLS-LDLT), explore their change trends over time and determine the normal reference intervals.Methods:This retrospective study involved the data from 261 pediatric LLS-LDLT cases in Tianjin First Central Hospital from June 2014 to January 2018. Hemodynamic parameters included peak systolic velocity (PSV), end diastolic velocity (EDV), resistivity index (RI), and pulsation index (PI) of hepatic artery (HA), and portal vein velocity (PVV) during intra-operative and on the 1st, 3rd, 5th and 7th days after operation were collected. Among whom, 232 cases with uncomplicated and normal recovery were finally involved in our study, with 200 cases who were collected from June 2014 to August 2017 as test group. Those collected from September 2017 to January 2018, totally 32 cases were set as validation group. The change trends and normal ranges of hemodynamic parameters over time were analyzed in test group, and the results were further tested in the validation group.Results:In the test group, PSV HA, EDV HA showed a similar change trend at one week after surgery, with an overall decrease-rise trend; RI HA, PI HA also changed similarly with an overall rise-decrease trend. PVV at surgery was lower than at all time points after surgery. In addition, this study provided the normal reference intervals of hemodynamic parameters for LDLT patients at early postoperative period, which at intra-operation they were PSV HA 18.4-98.3 cm/s, EDV HA 0-43.3 cm/s, RI HA 0.41-1.0, PI HA 0.51-2.0, PVV 19.0-83.7 cm/s. Within 1 week after surgery: PSV HA 21.0-97.7 cm/s, EDV HA 0-32.7 cm/s, RI HA 0.47-1.0, PI HA 0.62-2.0, PVV 23.0-92.0 cm/s. By using those results, the coincidence rate of Doppler parameter change trend was 84.3%(27/32), 84.3%(27/32), 78.1%(25/32), 78.1%(25/32), 87.5%(28/32) for PSV HA, EDV HA, RI HA, PI HA, PVV in the validation group, respectively. As for the normal reference intervals of blood flow parameters, RI HA and PI HA in one case in the validation group were lower than the lower limits of the normal reference intervals, accounting for 3.1% of the total. PSV HA in two cases was lower than the lower limit of normal reference interval, accounting for 6.2% of the total. Conclusions:The hepatic hemodynamic in post-transplanted children detected by DU has specific changing trends and normal ranges, which provides valuable reference values for ultrasonologists and pediatric transplant clinicians.

With the continuous advancement of the deepening reform of the medical security system, the medical insurance payment method, as an important part of it, has become the focus of the reform. As one of the main types of innovative payment methods, payment for performance combines payment and medical service quality to improve the efficiency of medical and health services and patient satisfaction. In order to accelerate the clinical application of new medical technologies, improve patients′ access to innovative technologies, and reduce the disease economic burden of patients, Shanghai has carried out a pilot reform of paying for performance for three new technologies including Cryoablation in the treatment of cancer, Da Vinic Robotic Surgical System and Plasma MicroRNA Panel detection. Through multiple rounds of expert consultation and on-the-spot investigation, the positive detection rate, complication rate and tumor reduction rate were finally determined as the performance evaluation indicators of the three technologies, and the corresponding payment standards were defined. The pilot reform in Shanghai could provide reference for other regions to carry out performance based payment.
