1.Long-term treatment of chronic hepatitis B.
Chinese Journal of Hepatology 2014;22(12):884-890
Nucleoside and nucleotide analogs (NAs) have been successfully used for treatment of chronic hepatitis B. Hepatitis B virus (HBV) replication is now recognized as the key driver of liver injury and disease progression, so the primary aim of treatment for chronic HBV infection is to maximize sustained suppression of HBV replication to undetectable levels. The long-term treatment has also been shown to achieve substantial histological improvement and regression of liver fibrosis or cirrhosis, and reduction of hepatocellular carcinoma. This paper has reviewed the necessity, clinical benefits, and the management of long-term treatment for chronic hepatitis B.

Objective To investigate the distribution of acquired resistance-related genes and markers of mobile genetic elements, and their relationships in multidrug-resistant Escherichia coli. Methods From October 2008 to March 2009, 28 strains of multidrug-resistant Escherichia coli isolated from urine were collected from the Ningbo First Hospital. Then, 47 kinds of acquired resistance genes to beta-lactams, aminoglycosides, quinolones, 2 kinds of acquired drug efflux gene and 13 kinds of genetic markers of mobile genetic elements: conjugal plasmids, transposons, insertion sequences, and integrons were analyzed by PCR. The index cluster analysis was used to investigate their relationships. Results In 28 strains of Escherichia coli, 7 kinds of acquired beta-lactam-resistance genes, 8 kinds of acquired aminoglycosideresistance genes, 1 kind of acquired drug efflux gene, 2 kinds of genetic markers of conjugal plasmids, 3 kinds of genetic markers of transposon and insertion sequences, 1 kind of genetic marker of integron were detected; but other 46 kinds of genes were not detected. Two clusters, A and B, were divided by index cluster analysis depending on positive genes. Conclusions In this group of Escherichia coli, acquired resistance related genes may be associated with resistant phenotypes of antimicrobial agents. Horizontal transfer of mobile genetic elements may bring rapid spread of resistance of bacterial pathogens, not only among the same kind of pathogens, but also among the different kinds. In addition, index cluster analysis suggests that correlation might exist between acquired resistance-related genes and mobile genetic elements.

Abstract: To report on two patients with Coronavirus Disease 2019 (COVID-19) combined with diffuse connective tissue disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection followed for nearly 3 years, in order to understand the long-term effects on the patients' immune system. Both patients were male, aged 81-82 years, and were hospitalized with fever on January 29, 2020 and February 10, 2020, respectively. Both were diagnosed with COVID-19 after positive SARS-CoV-2 polymerase chain reaction (PCR) tests. After receiving anti-infection treatment, cough suppressants, ex‐pectorants, and symptomatic supportive treatment, their body temperature returned to normal and two consecutive PCR tests were negative for SARS-CoV-2, and they were discharged from hospital. However, due to recurring fevers and varying degrees of rheumatic disease-related symptoms, both patients were readmitted to the hospital, indicating the presence of positive auto‐ antibodies and organ involvement. One patient recovered from COVID-19 with recurrent fever, joint pain, muscle aches and subcutaneous nodules, and was subsequently diagnosed with undifferentiated connective tissue disease. The other patient developed recurrent fever, mouth ulcers and rash after recovery from COVID-19 and was subsequently diagnosed with anti neutro phil cytoplasm antibody (ANCA)-associated vasculitis (AAV). The patient was treated with glucocorticoids and immunosuppres sive drugs and the symptoms resolved rapidly and subsequent laboratory and imaging examinations showed stable condition. However, due to self-termination of medication, their symptoms quickly relapsed, and further treatment with glucocorticoids and immunosuppressive agents resulted in sustained stability of their condition. The erythrocyte sedimentation rate and hyper‐sensitive C-reactive protein remained within normal limits, and lung CT scans showed stable lesions with partial absorption.SARS-CoV-2 infection may have long-term effects on patients' immune systems, leading to abnormal immune responses and diffuse connective tissue disease. This suggests that regular follow-up observation of immune system-related diseases may be necessary for elderly patients with COVID-19.

BACKGROUND:The majority of published article on cardiopulmonary resuscitation (CPR) used healthy animals. In fact, patients commonly have severe heart diseases before CPR, leading to ventricular fibrillation. OBJECTIVE: To investigate outcome of myocardial function and cardiopulmonary resuscitation in myocardial infarction rats treated with bone marrow mesenchymal stem cells (MSCs) transplantation.DESIGN, TIME AND SETTING: A randomized, controlled animal experiment was performed at the University of Southern California and Second Hospital of Sun Yat-sen University from April to August 2007.MATERIALS: A total of 18 adult male SD rats were randomly divided into model control and cell transplantation groups with 9 animals in each group. In addition, 1 SD rat aged 1 month was used to prepare bone marrow MSCs.METHODS: Myocardial ischemia was induced by ligation of the left anterior descending artery (LAD). Animals respectively received 5×106 MSCs (0.1 mL) marked with PKH26 in phosphate buffer solution (PBS) or PBS alone 4 weeks after LAD ligation. Ventricular fibrillation and CPR were performed 4 weeks after MSCs or PBS injection.MAIN OUTCOME MEASURES: Heart function was evaluated by ultrasound cardiography 2, 4 weeks after transplantation; hemodynamics was measured before and 4 hours following CPR. Myocardial tissues were harvested 72 hours after CPR for pathological exanimation.RESULTS: Compared with model control group, ejection fraction of transplantation group was significantly increased 2 and 4 weeks after transplantation (P<0.01), and cardiac index, dp/dt40, and -dp/dt were significantly improved before and within 4 hours after CPR (P<0.01, P<0.05). Moreover, the rats survived longer in transplantation group (72 hours) after CPR compared with control group (P<0.05). Pathological section results showed a large number of PKH26-1abeled MSCs in the rnyocardium.CONCLUSION: Myocardial function, hemodynamics and survival time after CPR were significantly improved in animals treated with MSCs transplantation.
