We present a case with numbness of the left cheek because of the injury. The patient were treated by endoscopic assisted on the left infraorbital nerve decompression through the approach of the canine fossa. The symptom shows improvement after the operation. The patient feels numbness significantly ease on 4 months after the operation.

Objective To test the reliability and validity of the Chinese version of Quality-of-Life Questionnaire for Mechanically Ventilated Patients (QOL-MV). Methods The English version of QOL-MV was revised and translated into Chinese version. The reliability and validity of the Chinese version of QOL-MV was tested in 120 mechanically ventilated patients. Results The Cronbachαcoefficient of the Chinese QOL-MV was 0.904. The item-level content validity index of Chinese QOL-MV were 0.86-1.00 and the scale-level content validity index of Chinese QOL-MV was 0.92. Two factors were extracted by factor analysis and the cumulated variance was 80.18%. The dimensional factor loading of each item was greater than 0.565. The correlation coefficient between the score of Chinese QOL-MV and the Euroqol Group′s 5-domain 3 Level Questionnaire (EQ-5D) and Richards Campbell Sleep Questionnaire (RCSQ) was 0.947 and 0.561 respectively (P<0.01). Conclusions The Chinese version of QOL-MV has been proved to be reliable and valid.It can be used to measure the quality-of-life for mechanically ventilated patients.

Objective To observe the effect of beraprost sodium on elderly patients with type 2 diabetic nephropathy (DN) and to observe the change of the plasma vascular endothelial growth factor(VEGF) and endothelin(ET-1) level.Methods The levels of plasma VEGF and ET-1 in the 27 cases of type 2 diabetes without nephropathy and 48 cases with type 2 diabetic nephropathy were measured.The possible role of VEGF and ET-1 in diabetic nephropathy was explored.48 cases of type 2 diabetic nephropathy patients were randomly divided into 2 groups:the conventional treatment group and beraprost sodium treatment group.The changes of VEGF and ET-1 level in the 2 groups before and after the treatment were measured.Results The plasma VEGF and ET-1 levels were significantly higher in type 2 diabetic nephropathy patients than in type 2 diabetes patients without nephropathy(P <0.01).Compared with the control group,beraprost sodium significantly reduced the plasma VEGF and ET-1 levels in patients with diabetic nephropathy(P < 0.05),and also reduced urinary albumin excretion rates (UAER) significantly (P < 0.05).Conclusions The increasing level of VEGF and ET-1 plays an important role in the onset of diabetic nephropathy.Beraprost sodium can correct the balance of the plasma VEGF and ET-1 in treatment of patients with diabetic nephropathy,improves the endothelial function in diabetic nephropathy,decreases urine protein,and plays a protective role in diabetic nephropathy.

OBJECTIVE:To determine the equilibrium solubility of albendazole(ABZ)and its apparent oil-water partition coef-ficient. METHODS:The equilibrium solubility of ABZ in various solutions was determined at 37 ℃ by HPLC and saturation solu-bility method,including water,7 kinds of common organic solvents with different polarities(methanol,ethanol,etc.),organic ac-id(oleic acid,glacial acetic acid,lactic acid,formic acid),hydrochloric acid of pH 1.2,phosphate buffer solution(PBS)of dif-ferent pHs(2.0-7.8)and 6 kinds of common surfactants with mass concentrations of 10,50 and 100 mg/ml(polysorbate 80,polox-amer,etc.). The apparent oil-water partition coefficient(P)was calculated with the concentration ratio of ABZ in oil phase(N-oc-tyl alcohol)and water phase(water and PBS of different pHs)after partition equilibrium. RESULTS:The equilibrium solubility of ABZ reached(0.26±0.02)μg/ml in water,with the lgP of 3.66±0.01. The equilibrium solubility of ABZ in common organic sol-vents and organic acids was higher than in water. The higher the polarity of the organic solvent was and the weaker of organic acid was,the weaker of its ability to solubilize ABZ would be. The equilibrium solubility of ABZ was higher in the medium of pH 1.2-2.5 than in that of pH 5.0-7.8. The ability of the surfactant to solubilize ABZ was related to its type,and the higher of the mass concentration of the surfactant was,the stronger of its ability to solubilize ABZ became. lgP was less than 1.6 at pH 1.2-2.0 and changed little at pH 5.0-7.8 [(3.71 ± 0.26)-(3.68 ± 0.26)]. CONCLUSIONS:ABZ is insoluble in water. Its equilibrium solubility demonstrates a negative correlation with the polarity of the organic solvent and a positive correlation with the acidity of the organic acid and with the mass concentration of the surfactant. It has higher water solubility and lower lipid solubility in a strong acidic en-vironment,and higher lipid solubility and weaker water solubility in weak acidic,weak basic and neutral environments.

OBJECTIVE:To optimize freeze-drying technology of albendazole nanosuspension so as to prepare albendazole nanometer powder. METHODS:By adopting freeze-drying method,with particle size and Zeta potential as the indexes,single fac-tor test and verification were made on pre-freezing temperature and the type,ratio and mass fraction of cryoprotectants,and then the albendazole nanosuspension prepared by liquid phase precipitation method was made into albendazole nanometer powder. RE-SULTS:When the pre-freezing temperature was-20℃and the cryoprotectant was 4%glucose-mannitol(3∶7),the average parti-cle size of the prepared nanometer powder was (208.03 ± 2.13) nm,and average Zeta potential was (-15.53 ± 0.18) mV. CON-CLUSIONS:Albendazole nanometer powder with better particle size and potential can be prepared by freeze-drying technology.

Objective To investigate the effect of long hairpin RNA ( lhRNA) expression vector targeting HBV X gene ( HBx) on replication of hepatitis B virus ( HBV) and gene expression.Methods Four kinds of small interference RNAs ( siRNAs) were synthesized and lhRNA expression vectors targeting HBx were constructed.Four siRNA oligonucleotides and two lhRNA expression vectors were transfected into HepG2.2.15 cells.HBsAg, HBV DNA in culture supernatants and HBx mRNA in HepG2.2.15 cells were detected by time-resolved immunofluorometric assay, real-time quantitative PCR, and reverse transcription PCR, respectively.Negative sequence group or empty vector group was taken as the control.Independent-samples t test was performed to evaluate the inhibition effect on replication of HBV and gene expression. Results Compared with the negative control, HBsAg, HBV DNA level in culture supernatants and HBx mRNA in HepG2.2.15 cells were significantly decreased after siRNA-1 and siRNA-4 transfected at high concentrations (60 nmol/L or 90 nmol/L) (P<0.05), especially the HBsAg and HBV DNA levels in the siRNA-1 transfection group, which were significantly decreased at 24, 48 and 72 h after transfection ( P<0.05 or P <0.01 ) . Two lhRNA expression vectors ( pMD-HBxlh1 and pMD-HBxlh4 ) were successfully constructed and transfected into HepG2.2.15 cells, HBsAg and HBV DNA level in transfected cells was significantly lower than those in negative control (P<0.05).Conclusion The novel siRNA-1 is confirmed to target HBx gene and lhRNA expression vector targeting HBx can effectively inhibit the replication of HBV and expression of HBV gene.
