Nucleoside analogues have been the mainstay of clinical treatment of herpes simplex virus 1 (HSV-1) infections since their development. However, the emergence of drug resistant strains has underlined the urgency of the discovery of novel anti-HSV-1 drugs. Natural products, which provided many novel drug leads, are known to be an important source of anti-HSV-1 agents. Herein, we present an overview of natural products with anti-HSV-1 activities isolated from a variety of plants reported in recent years. Several different compounds, mainly belonging to the three groups of polysaccharides, polyphenols and terpenes, showed antiviral effects against HSV-1, indicating their potential to be promising anti-HSV-1 agents.

Objective To systematically evaluate the clinical efficacy and safety of azithromycin (Az) versus amoxicillin-clavulanic acid (A-Cva) in the treatment of some acute respiratory infections in children. Methods Pubmed, EMBase, Medline, Cochrane Library and CJFD were retrieved to collect the randomized controlled trial (RCT) of their clinical efficacy and safety in the treatment of acute respiratory infections in children. The methodological quality of included studies was evaluated. The RevMan5.2 software was chosen for data analysis. Results Twenty RCTs involving 4980 pediatric patients were included for assessment of the clinical efficacy. Meta-analysis showed that Az had more significant effect on the treatment of some bacterial repiratory infections in children (OR=0.78, 95%CI (0.65,0.93), P=0.007) than A-Cva. In the treatment of upper respiratory infections, acute otitis media and so on, Az had more significant effect (OR=0.75, 95%CI (0.62,0.91), P=0.003); in the treatment of lower respiratory infections, such as community acquired pneumonia and so on, Az and A-Cva acid had the similar effect (OR=1.20, 95%CI(0.62, 2.33), P=0.58). Thirteen RCT involving 3474 pediatric patients were included for assessment of the clinical safety. Meta-analysis shows that the difference between Az and A-Cva is statistic significant in the treatment of some bacterial repiratory infections in children (OR=0.49, 95%CI (0.40, 0.60), P<0.000 01). Conclusion Overall, Meta-analysis shows that Az is more effective and safer in the treatment of some bacterial repiratory infections in children than A-Cva.

Objective To study Keshan disease and its developmental trend in Zhangjiakou City in 2010 and to provide a scientific basis for further prevention of the disease.Methods From the eight diseased counties of Zhangjiakou City,five diseased countries were selected; in each diseased county a diseased village was selected as the clinical investigating point.Physical examination and Electrocardiography (ECG) tracings were carried out to suspicious patients with Keshan disease.Suspected heart enlargement,and ECG abnormalities were taken anteroposterior chest X-ray to measure the cardiothoracic ratio.Results A total of 2519 people were examined,16 cases were diagnosed as chronic Keshan disease,79 as latent Keshan disease,and the detection rate was 0.64％ (16/2519) and 3.14％(79/2519),respectively.Total of 2519 ECG tracings were taken,and electrocardiogram abnormalities were 268 cases,with a abnormal rate 10.64％,and most of them were complete right bundle branch block[accounted for 17.16％ (46/268)].Totally 94 cases of anteroposterior chest X-ray films were taken and 42 cases were cardiac enlargement,with a detection rate 44.68％.The numbers of mild,moderate and severe cases were 20,12 and 10,respectively,and the constituent ratio was 47.62％ (20/42),28.57％ (12/42),23.81％ (10/42),respectively.Conclusions The incidence of Keshan disease in Zhangjiakou City is relatively low,and the condition is stable.But monitoring and comprehensive prevention and control measure still should be strengthened.

Objective To analyze the epidemiological characteristics of Mycobacterium tuberculosis by enterbaeterial repetitive intergenic consensus-polymerase chain reaction(ERIC-PCR)DNA fingerprint. Methods Mycobacterium tuberculosis positive sputum samples between September 2003 to May 2006 were collected and cultured.Chromosomal DNA were extracted and ERIC-PCR DNA fingerprinting was analyzed by software,such as RAPD PHYLIP and Treeview.Results A total of 42 different fingerprints were detected.Phylogenetic analysis showed that they could be classified into three clusters,the clustering rate was 72.6%.The characteristics of ERIC-PCR fingerprint patterns were related to age,drug resistance,and type of resistance.Conclusions ERIC-PCR DNA fingerprinting technique used in this study is good for epidemiological studies with its strong discrimination,simplicity and rapidness.A high level of recent transmission is found in our city.

Objective To determine the diagnostic value of anti-mutated citrullinated vimentin(anti- MCV)antibodies for rheumatoid arthritis(RA).Methods The anti-MCV were determined in 136 patients with RA,80 non-RA patients and 19 normal peoples.The diagnostic value of anti-MCV was assessed and compared with anti-CCP,AKA and RF.Results The sensitivity and specificity of anti-MCV in the 136 RA patients was 95.6% and 80.8% respectively,there was significanl difference between the test group and the control group(P

Objective:To investigate the efficacy and safety of Rituximab (RTX) in treating children with refractory steroid-resistant nephrotic syndrome (SRNS).Methods:The clinical data of 10 children with refractory SRNS receiving RTX in the Department of Pediatrics, Jinling Hospital from September 2013 to March 2018 were analyzed retrospectively.Results:The age of onset of 10 children (including 5 males and 5 females) was (4.47±2.75) years old.The renal biopsy showed focal segmental glomerular sclerosis in 5 cases (50%), minimal change nephropathy in 3 cases (30%), IgM nephropathy in 1 case (10%), and mesangial proliferative glomerulonephritis in 1 case (10%). Ten children received RTX treatment (1 or 4 doses; 375 mg/m 2 once; maximum: 500 mg) at the age of (6.74±2.62) years old.There were 8 patients (80%) receiving a single dose of RTX, 1 patient (10%) receiving 3 doses, and 1 patient (10%) receiving 8 doses.The follow-up time was 11.93 (5.17, 25.66) months.The remission rates at the 3-month follow-up, 6-month follow-up and last follow-up were 30% (3 patients), 40% (4 patients), and 40% (4 patients), respectively.The 24-hour urinary proteinuria and serum albumin levels were improved in 10 children after RTX treatment, but there were no significant statistical difference(all P>0.05). No significant difference was found in humoral immunity and renal function before and after RTX treatment (all P>0.05). During the treatment and follow-up, 3 patients (30%) developed infusion reaction, 2 patients (20%) showed severe pulmonary infection, and 1 patient (10%) died of severe pulmonary infection. Conclusions:RTX is effective in treating some children with refractory SRNS, and a long-term follow-up should be conducted to prevent infection.

The amino acid sequence of the fusion protein FP3 was measured by two types of LC-MS/MS and its primary structure was confirmed. After reduction and alkylation, the protein was digested with trypsin and glycosyl groups in glycopeptide were removed by PNGase F. The mixed peptides were separated by LC, then Q-TOF and Ion trap tandem mass spectrometry were used to measure b, y fragment ions of each peptide to analyze the amino acid sequence of fusion protein FP3. Seventy-six percent of full amino acid sequence of the fusion protein FP3 was measured by LC-ESI-Q-TOF with the remaining 24% completed by LC-ESI-Trap. As LC-MS and tandem mass spectrometry are rapid, sensitive, accurate to measure the protein amino acid sequence, they are important approach to structure analysis and identification of recombinant protein.

BACKGROUND: Researches on the hand allograft have been transited from laboratory aspects to clinical application.OBJECTIVE: To evaluate the clinical significance of serial monitoring of co-stimulating signals in double hand transplantation.DESIGN: Case controlled observation.SETTING: Department of Traumatic Orthopaedics, Nanfang Hospital,Southern Medical University.PARTICIPANTS: From September 2001 to December 2001, a patient who was proposed to have double hand transplantation in the Department of Traumatic Orthopaedics, Nanfang Hospital Affiliated to Southern Medical University was taken as the subject of the experiment, meanwhile 15healthy adult man were enrolled as controls.METHODS: Before operation, blood sample was collected from the patient once before given immunodepressant and twice after given immunodepressant; blood sample was also collected before arteriovenous connection during operation, as well as once a day during the first week after operation, once every other day on the second week, twice a week on the third and fourth week, followed by once a week for total two month. The first week after operation was taken as inducing period with the remainder as maintaining period. 2 mL peripheral venous blood was collected from healthy adult and anti-coagulated by EDTA of mass scores of 20 g/L.Flowcytometry was used to carry out a serial monitoring of T cell surface co-stimulating moleculars (CD28, CD54, CD11a).MAIN OUTCOME MEASURES: The change of co-stimulatingmolecules on the surface of T lymphocyte before and after transplantation.RESULTS:The changes of the three co-stimulating molecules were consistent with each other after double hand transplantation (CD28,CD54,CD11a),displaying decrement during inducing period comparing to pre-operation [(9.84±5.28)%, (55.50±3.62)%; (71.03±5.33)%, (95.10±1.26)%;(9.40±9.17)%, (29.70±3.23)%] and keeping at lower level at maintaining period [ (22.54±6.56) %, (91.28±8.12 ) %, ( 11.22±4.08 ) %].CONCLUSION:The serial monitoring of the co-stimulating signals in the peripheral blood of patients with linb allograft is beneficial to the observation of the posopertaive immunologic reaction, providing important guidance for the application of immunosuppression medicine, as well as the prediction and diagnosis of postoperative immune rejection. Meanwhile, costimulating signal induced immunological tolerance is proved promising for the application of hand transplantation.
