0.05) and the cost-effectiveness ratios were 1 898.85 and 1 599.81,respectively.CONCLUSION:Levoflocaxin is superior to cefoperazone sodium/sulbactam sodium for community acquired pneumonia.

Objective To explore the role of phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT) pathway in recombinant human erythropoietin( rhEPO) protecting new type BPD. Methods Injected LPS or PBS to 40 spra-gue-dawley (SD) rats, gestational sacs on 15th day of gestation, the newborn rats were divided into four groups:control group, hyperoxia group, rhEPO group, rhEPO+LY294002 group. To detect the expression of lung tissue BCL-2 and Caspase - 9 protein and mRNA by Western blot and RT-PCR. Results In the hyperoxia group and rhEPO+LY294002 group, BCL-2 expression was decreased,while Caspase-9 expression was increased apparently;in the rhEPO group, BCL-2 expression was increased, while Caspase-9 expression was decreased. The differences between each group were statistically significant on 1st,7th and 14th day of hyperoxia exposure (P<0. 05). Con-clusion Intrauterine inflammatory exposure combined with hyperoxia after birth can cause lung cell apoptosis in-creases. While rhEPO has certain control effects on BPD, possibly by reducing the pulmonary apoptosis. The mechanism may be associated with PI3K/AKT signaling pathway.

In patients with initially diagnosed unresectable cancers,resection of cancer sometimes becomes possible by systemic chemotherapy,and this model of chemotherapy is defined as conversion chemo-therapy. Conversion chemotherapy can improve objective response rate and resection rate,and it has shown an important value in metastatic colorectal cancer,advanced gastric cancer and unresectable hepatocellular carci-noma.

Gastrointestinal microbiota is a huge and complex system that has multiple influential factors. As an exogenous pathogen,Helicobacter pylori(Hp)may interact with gastrointestinal microbiota. It has been revealed that Hp infection led to an increase in Lactobacillus acidophilus in intestinal tract and a decrease in Actinobacteria,Bacteroidetes and Firmacutes in stomach. Proton pump inhibitors and antibiotics,the major components of eradication regimens for Hp infection,may also have an impact on gastrointestinal microbiota. On the other hand,gastrointestinal microbiota interferes with Hp’s attachment into gastric mucosa. Probiotics combined with eradication therapy could benefit the eradication rate of Hp infection and reduce adverse events.

626 adolescent patients undergoing orthodontic treatment were divided into 4 groups according to the oral health score and ap-pointment score.(1)The score in highly educated two-parent family is higher than that in highly educated single-parent family,and the score of oral hygiene in highly educated family is higher than that in lowly educated family(P <0.05).(2)There is no statistical difference between two-parent family and single-parent family in oral hygiene when they have equal educational background.

Objective To optimize the formulation of self-microemulsifying drug delivery systems containing tanshinone ⅡA(tanshinone ⅡA-SMEDDS) and assess the quality of tanshinone ⅡA-SMEDDS. Methods Pseudoternary phase diagrams were used to choose the oil,emulsifier,co-emulsifier,and their proportion in the formulation on the basis of the ability to form emulsions and regions. Then the self-emulsifying time,droplet and morphology,size distribution,?-potential,stability,and other aspects of the quality were evaluated. Results The formulation of tanshinone ⅡA-SMEDDS was as follows:ethyl oleate-Labrasol-PEG 400=10%:45%:45%,drug loading ratio was 2.25 mg/g. The self-microemulsifying time of tanshinone ⅡA-SMEDDS in 0.1 mol/L hydrochloric acid solution was less than 1 min,the emulsion drops were spherical shape with average particle size of (84.9?2.1) nm and the average ?-potential (-24.0?1.15) mV (n=3). So tanshinone ⅡA-SMEDDS was stable. Conclusion In this paper,the tanshinone ⅡA-SMEDDS has a good self-emulsifying performance. It is expected to further stabilize the preparation of tanshinone ⅡA self-microemulsifying agents.

The surgical intervention and criteria of severe acute pancreatitis has significantly changed in the last several years with the advent of enhanced imaging techniques and minimally invasive surgery.Many kinds of minimally invasive technologies which take laparoscopy as a representative are constantly applied to the treatment of severe acute pancreatitis and make its mortality and postoperative complication rate decrease obviously.However,there are many different ways using laparoscopic techniques to treat severe acute pancreatitis.In this review,the author will discuss the current status of the different approaches.

As a way of gene modification,alternative splicing is an important factor of eukaryotic gene expression and regulation.It makes various transcripts from one protein-coding gene,and greatly extends the genetic information.Alternative splicing of pre-messenger RNA plays an important role in tumor cells.By alter-native splicing,some important genes can generate splicing variants different from those in normal cells.The existence of tumor-specific splicing variants leads to the occurrence and progression of tumor.Therefore,explo-ration on the alternative splicing of tumor-associated genes may be of great significance in tumor diagnosis and treatment.

As small non-coding RNAs,microRNAs (miRNAs)have been recognized as important reg-ulatory factors in the post-transcription regulation network.Studies have shown that miR-133a and miR-133b, as members of miR-133 family,can regulate the expression of target genes such as epidermal growth factor receptor and oncogene.They regulate the mitogen-activated protein kinases and protein kinase B signaling path-ways,which affect tumor cell proliferation,invasion and migration.MiR-133 plays a key role in the process of tumor development and progression,suggesting that it could be served as a new target for cancer treatment.
