?AIM:To investigate the effects of Bevacizumab on the proliferation and the expression of E -Cadherin and fibronectin in human retinal pigment epithelial cell ( ARPE-19) in vitro.?METHODS: Different concentrations (0, 0.625, 1.25, 2.5, 5.0mg/mL) of bevacizumab were exposed to ARPE-19 cells, then cell viability was analyzed by CCK-8, cell cycle was determined by flow cytometry, and the expression of E-Cadherin and fibornectin was detected by Western blot and RT-PCR.?RESULTS:The concentration as 2.5mg/mL or 5.0mg/mL of bevacizumab was shown to effectively suppress the proliferation and cell cycle of ARPE-19 cell (P<0.05). In addition, 2.5mg/mL or 5.0mg/mL of bevacizumab could downregulate the expression of E-cadherin and promote the transcription of fibronection gene (P<0.05).?CONCLUSION:High concentration of bevacizumab was able to inhibit ARPE-19 proliferation, downregulate E-Cadherin expression and promote fibronectin expression, indicating epithelial-mesenchymal transition induced by bevacizumab in ARPE-19 cell.

Objective To study the effects of the duration and degree of the peripheral facial paralysis due to middle ear cholesteatoma on the recovery of postoperative nerve functions.Methods The clinical data of 30 cases (single ear) of patients with cholesteatoma complicated with facial paralysis were retrospectively analyzed.The mean age was 54.7±8.9 years old (range 21~77years old) including 17 males and 13 females.The duration of facial paralysis, degree and location of facial nerve injury,surgical timing of facial nerve decompression,recovery of facial paralysis after surgery were followed up.According to the course of paralysis, the patients were divided into ≤2 months group (14 cases) and >2 months group (16 cases).According to the degree of paralysis, the patients were divided into the incomplete facial paralysis group (III-IV grade,14 cases) and the complete facial paralysis group (V-VI grade,16 cases).The influence of the course and degree of paralysis on the postoperative recovery of neurological function were analyzed by the Fisher exact probability test.Results Three cases underwent open radical surgery with no facial nerve damage confirmed by intraoperative exploration, and their postoperative facial nerve functions were fully restored.Facial nerve canal damage was found in 27 cases, accompanied by facial nerve congestion, edema or granulation formation.Among them, the facial nerve damage location was the tympanic segment in 20 cases.The open radical operation and local facial nerve decompression were carried out, and the postoperative facial paralysis recovery rate was 46.67%(14/30).The facial nerve function recovery rate in less than 2 months group was higher than the >2 months group (P<0.05).The facial nerve function recovery rate of the incomplete paralysis group was higher than the complete facial paralysis group (P<0.05).Conclusion This study suggests that facial nerve damage most occurred in the tympanic segment of the facial nerve.Radical mastoidectomy and local facial nerve decompression are effective for the treatment of middle ear cholesteatoma complicated with facial paralysis.The shorter course and lighter degree of paralysis lead to the better postoperative recovery of neurological function.

Objective:To provide ideas for the participation of clinical pharmacists in clinical individualized medication.Methods:Clinical pharmacists participated in the clinical consultation for one senior patient with acute cholangitis treated with biapenem.Results:The consultation comments and suggestions proposed by clinical pharmacists were accepted by clinics,which played an important role in assisting doctors in the rational drug use and significantly improved the medical treatment.Conclusion:Clinical pharmacists should participate in individualized medication and help clinicians optimize drug therapy,which can improve the safety and efficacy of medication.

Objective To solve the problem of army hospital expenditure over budget software controlling.Methods In the army hospital accounting reckoning system,database trigger mechanism was used to intelligently control expenditure over budget.Results Expenditure was controlled strictly and intelligently.Financial problems were checked effectively.Conclusion The methods that automatically control budget by trigger is simple and effective.It enhances budget management of hospital effectively.

Objective To search for a candidate DNA vaccine of Fasciola hepatica. Methods Using RT-PCR and digestion with Hind III and BamHI, Fasciola hepatica secreted cathepsin L1(FheCL1) cDNA was cloned into the expression vector pcDNA3.1. Results The cloning was successful, the cDNA sequence and its deduced amino acid sequence were analyzed. There was much difference between the cloned FheCL1 and the published one. But the first 20 residues of their amino acid sequences were the same. Conclusion The recombinant plasmid pcDNA3.1-FheCL1 may be a new type of candidate DNA vaccine candidate for Fasciola hepatica. It is possible that Fasciola hepatica presents different sub-species but their amino acid residues (1 to 20) encoded by FheCL1 might build up membrane spanning helix.

Aim To investigate the effects of ?,?-methylene ATP ( ?,?-MeATP) on the P2X1 purino-ceptor-mediated vasoconstriction by different administration ways in the rat mesenteric artery. Methods Isometric vasoconstrictive responses to ?,?-MeATP,administered in non-accumulative manner or single concentration manner,were recorded in the rat isolated mesenteric arterial rings. Results ?,?-MeATP ( 10 -7 ～ 10 -4 mol ? L -1 ) administered in both of the two manners produced concentration-dependent vasocon-strictive responses in the rat isolated mesenteric artery. The vasoconstrictive responses to ?,?-MeATP in single-concentration administration group were greater than those in non-accumulative administration group when the vasoconstriction was standardized either by tissue wet weight or by maximal response to 120 mmol ?L-1 KCl ( P

The thalamic reticular nucleus (RT) is a sheet-like nucleus which surrounds the anterolateral aspect of the dorsal thalamus. In this study, we present data on the connections of the dorsocaudal portion of the RT in hamsters using anterograde, retrograde and transneuroual fiber tracing techniques. After injection of one eye with a mixture of ~3H-proline and ~3H-fucose (2 animals; 10 and 15 days survival time), transneuronal label was located in the dorsocaudal portion of the RT (dc RT) on both sides of the thalamus.After separate injection of horseradish peroxidase (HRP) into the thalamic lateral posterior nucleus (LP), dorsal and ventral nuclei of the lateral geniculate body (LGd, LGv) (8 animals, one day survival time), HRP labelled neurons wereobserved in the dorsal, middle and ventral area of the ipsilateral dc RT respectively.A small iontophoretic injection of a mixture of ~3H-proline and ~3H-leucine was made into different sites of area 17 in each of 3 hamsters (one day survival time),in each case an elongated patch of label was located in nearly the entire rostrocaudal extent of the ipsilateral dc RT. A caudal Injection in area 17 resulted in labelling the dorsal area while a progressively more rostral injection resulted in labelling a more ventral area of the dc RT.Thus, the dorsocaudal portion of the RT can be defined as the visual portion of the nucleus because it has connections with many of the known visual centres, namely, the visual cortex, LP, LGd, LGv Furthermore, because of the topographic connection with area 17 and the visual thalamic nuclei, the notion that the dc RT as a nucleus which is capable of processing specific and localised visual information. should be considered.
