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 the safety and efficacy of target-controlled infusion (TCI) sedation with low dose ketamine and propofol during rigid cystoscopy in elderly male patients. Methods Forty-five elderly male patients with I - III grade of the American Society of Anesthesiologists (ASA)rigid cystoscopy examination were divided into 3 groups randomly: group A, 2% lydocaine gel was filled in urethra, n=15; group B, 2% lydocaine gel filled with propofol TCI sedation, n=15; group C, 2% lydocaine gel filled with combined ketamine and propofol TCI sedation, n= 15. The mean artery pressure (MAP), heart rate(HR), pulse oxygen saturation (SPO2)were measured at 5 time points; preoperation, during local anesthesia, inserting the scope, during testing and the end of testing. The concentration of effect room, wake time when alertness and calm grading (OAA/S)was 3 scores in B and C groups and visual analogue scale( VAS) score of pain after operation were detected. Results The MAP and HR at the time point of inserting the scope in group A had significant difference,compared with preoperation(P0. 05) . In group A, 10 cases pain VAS score were light pain, 4 moderate and 1 severe. In group B and C,no pain and no memory of the operation were reported. Conclusions TCI sedation with low dose of ketamine and propofol in elderly male patients under rigid cystoscope has good effects on sedation, analgesia and anterograde amnesia. The hemodynamics is stable and wake time is short.

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.

The major surgical managements for tibial plateau fractures are anatomical reduction, firm fixation and bone grafting. There have appeared many new techniques in recent years, such as less invasive stability system (LISS) and arthroscopy assisted treatment. But such complications as loss of reduction, infection, soft tissue lesion around the knee, nonunion, posttraumatic arthritis, and knee stiffness seem to be inevitable. This article introduces the mechanism, treatment and prevention of the complications of the tibial plateau fracture.

OBJECTIVE: To compare the efficacy and safety of bevacizumab plus FOLFIRI program or FOLFOX program for metastatic colorectal cancer.

OBJECTIVE: To establish the method to analyze γ-hydroxybutyric acid (GHB) and its precursors 1,4-butanediol (1,4-BD) and gamma-butyrolactone (GBL) in urine through LC-MS/MS and provide evidence for related cases. METHODS: GHB-d6 and MOR-d3 were used as the internal standard. The urine sample was separated by LC after protein precipitation with methanol. The electrospray ion source was for ionization. Each compound was detected through multiple-reaction monitoring (MRM) mode. RESULTS: The limits of detection of GHB and its precursors 1,4-BD and GBL were 0.1, 0.1 and 2 μg/mL. The accuracy was 87.6%-98.1%. The intra-day and inter-day precisions were less than 15% and matrix effects were higher than 80%. CONCLUSION The method is high sensitive, simple, rapid, specific and with high reliability. This study has provided technical support and basic data for forensic cases involving GHB.

Objective:To examine the osmolality of domestic recombinant human interferon α2b injection to provide evidence for the improvement of the national quality standard. Methods:Totally 66 batches of recombinant human interferonα2b injection produced by 9 manufacturers were withdrawn, and the osmolality was determined according to the appendix of Chinese Pharmacopoeia Ⅲ(2010 edition). The results were analyzed with statistical methods. Results:The pass rate of osmolality was 98. 5%. The osmolality of more than 90% of the batches was between 85% and 115% of the intermediate value set by the manufacturers. Conclusion:Comprehensive understanding of the quality control of osmolality of domestic recombinant human interferon α2b injection is obtained, which provides data support for the improvement of quality standard of osmolality.
