AIM: To investigate the effect of tetrandrine (Tet) on proliferation of human pterygium fibroblasts (HPF) in vitro and to search for a new method to prevent the recurrence after pterygium surgery.METHODS: With different concentrations (0 to 160μmol/L) of Tet acting on HPF cultured in vitro, the impact was observed at 24, 48, 72 hours respectively after Tet intervention. The MTT method was used to assay the biologic activities of Tet and inhibitive rate of cell growth. The expression of proliferating cell nuclear antigen (PCNA) in each group was detected by immunohistoche-mistry before and after Tet intervention.RESULTS:With different concentrations of 20, 40, 80 and 160μmol/L and acting for 24 to 72 hours, Tet could inhibit the proliferation of HPF in a dose- and time-dependent manner (P<0.05). After the intervention of Tet, the expression of PCNA protein declined. When the concentration of Tet was in the range of 20 to 160μmol/L, it was able to inhibit the expression of PCNA in a concentration-dependent manner (P<0.05).CONCLUSION:Tet could significantly inhibit the proliferation of pterygium fibroblasts, and the inhibitive action was in a dose- and time-dependent manner within a certain range of concentration. But in high concen-tration (>160μmol/L), Tet would have cytotoxity.

The over-expression of Polo-like kinase 1(Plk1)is critical in the producing and progressing of multi-ple human tumors and is recognized as an effective target for the development of novel anti-cancer drugs.Currently a variety of small molecules targeting ATP or substrates binding sites have entered different stages of clinical trials.Polo-box domain(PBD)is a unique domain of Plks which plays an important role in the sub-cellular location of Plks and also in the recognition of their substrates,therefore it has become an attractive target for the development of novel target-directed Plk1 inhibitors.In this paper,PBD function of Plk1 was intro-duced,the progress of small molecule and phosphoserine /phosphothreonine contained short peptide Plk1 inhibi-tors targeting PBD was summarized.Further development of this kind of inhibitors was also proposed.

The manuscript introduced the overview, training objectives, policy advantages, training process,curriculum, examination of the Australian College in Rural and Remote Medicine and further contrasted that with China's domestics.The authors held that Australia's training is better targeted due to its colleges tailored to this end;the training duration for general practitioners of rural and remote areas is longer,and the training schedule is reasonable;the curriculum design and training content are more targeted;and the homogeneous training is better achieved as its examination is run by the college in a standardized manner.The authors therefore hold that China should develop detailed regulations for general practitioners from rural and remote areas and explore the feasibility of setting up second-level disciplines institutes for internal medicine, surgery, gynecology and obstetrics, pediatrics and general at national and provincial level.

Objective To investigate the role of staging nutrition(SN) in the treatment of severe acute pancreatitis(SAP). Methods One hundred patients with SAP treated in our hospital since 1997 were randomly divided into two groups: Total parenteral nutrition group(TPN group,50 cases) and staging nutrition group (SN group,50 cases). The curative effects and complications between two groups were analyzed and compared. Results The incidences of total complications,incubation complication,double infection,hepatic function injury,abdominal cavity infection and hospital stay in SN-group were significantly lower than those in TPN-group(all P

BACKGROUND: How to promote the regeneration after peripheral nerve injury, especially after large defects, is a difficulty to be solved.OBJECTIVE: To review the mechanism of Wallerian degeneration and the development of nerve conduits.METHODS: PubMed database was searched for the literatures addressing the modular mechanism of Wallerian degeneration and nerve repair using the English keywords peripheral nerve regeneration, Wallerian degeneration, nerve guidance conduits. A total of 74 eligible literatures were included based on the exclusion criteria.RESULTS AND CONCLUSION: Rat SARM1 and fruit fly dSARM have been found to be highly implicated in Wallerian degeneration, indicating that the changes of nicotinamide adenine nucleotide/nicotinamide adenine dinucleotide may be related to the activated SARM1. Whether delaying Wallerian degeneration is good or bad is still in dispute. The future study should focus on the early inhibition of Wallerian degeneration and promotion of neuroregeneration following peripheral nerve injury.

Objective To investigate the expression and effect of miR-22-3p in non-small cell lung cancer (NSCLC). Methods The miR-22-3p expression level in seventy-six NSCLC tissues and para-cancer tissues was detected by qRT-PCR. The relationship between the expression of miR-22-3p and gender,age,tumor size,histolo-gy grade,pathological type and lymph node metastasis was analyzed. The function of miR-22-3p on the prolifera-tion of NSCLC cells was tested by growth curve assay. Target genes of miR-22-3p were predicted by online software Targetscan. Luciferase reporter assay and qRT-PCR was used to certificate the prediction. Results The expression of miR-22-3p was increased in NSCLC tissues than the para-cancer tissues and was correlated to lymph node metas-tasis. Overexpression of miR-22-3p could suppress the proliferation of A549 cells. Astrocyte-Elevated Gene-1(AEG-1) was predicted to be a target of miR-22-3p. MiR-22-3p was revealed to bind to AEG-13′UTR by luciferase report-er assay. Overexpression of miR-22-3p could inhibit the expression of AEG-1 in A549 cells. Suppression of miR-22-3p could increase AEG-1 expression. Conclusion MiR-22-3p could inhibit the proliferation of NSCLC by tar-geting AEG-1.

Total RNA was extracted from leaf of Suaeda hetroptera kitag, then the CMO ( choline monooxygenase) cDNA was amplified using the reverse transcriptase polymerase chain reaction ( RT-PCR) method and cloned into pMD-T-simple vector. The positive clones from the Blue/White Screen were sequenced. After confirming its validity, the CMO gene fragment was cloned into pBI121 vector. Double enzyme restriction and PCR analysis indicated that the pBI121/CMO recombinant plasmid was successfully constructed.
