3 d) were noted.CONCLUSION:The Clindamycin should be used in line with the perioperative preventive medication principle by strictly following its indications to ensure the safety and rationality of its clinical use.

OBJECTIVE:To standardize and improve the package inserts of Traditional Chinese medicine injections,and to guide clinical rational drug use and reduce incidences of adverse drug reactions(ADRs).METHODS:The package inserts of 34 kinds of traditional Chinese medicine injections commonly used in the clinic were subjected to an analysis.RESULTS & CONCLUSION:Part of the package inserts were not standard in writing contents in that they are unscientific and incompact,which thus remain to be improved.

OBJECTIVE: To evaluate the efficacy and safety of tacrolimus (FK506) instead of cyclosporine (CsA) in renal transplant recipients with hepatic impairment. METHODS: Eighteen patients with hepatic impairment, including 10 male and 8 females, aged 19-68 years (mean aged 40 years), 2 out of them suffered diabetes mellitus, 1 of them had hepatitis B prior to operation. After operation, all patients were treated with CsA 6 mg/(kg?d), the mass concentration was changed from 250-400 ?g/L at 1 month after operation to 250 ?g/L after half year. Totally 30 mg/d prednisone was used at first and changed to 20 mg/d at 1 month after operation. Mycophenolate was applied with 1.5 g/d, or azothioprine 50-100 mg/d. FK506 was used instead of CsA when alanine aminotransferase was over 1 500 nkat/L, with over 25.1 ?mol/L bilirubin direct. The initial dose of FK506 was 0.1 mg/(kg?d) at the second day after drug withdrawal and adjusted to base on its blood trough levels and the degree of hepatic impairment. The dosage of mycophenolate or prednisone was invariably. RESULTS: Hepatic function and bilirubin metabolism of all patients were returned to normal leverl without reject reaction in 15-60 days. One patient, who had severe hepatic impairment, was recovered in 46 days. Five patients had high blood sugar levels, and one had high blood cholesterol. After hypoglycemic and cholesterol lowering therapy, the blood glucose was controlled below 7.5 mmol/L from at the beginning of (16.7?2.8) mmol/L, and the blood fat was kept in a normal level. CONCLUSION: FK506 substituting for CsA can recover hepatic function with high safety in recipients with hepatic impairment.

Objective To observe the expression and correlation of Twist,p53 and E-cadherin mRNA in breast cancer.Methods Thirty breast cancer tissue and adjacent noncancerous tissue in patients underwent modified radical surgery,and the normal breast tissue in 10 patients with benign breast lesions,respectively,were detected the expression of Twist,p53 and E-cadherin mRNA by RT-PCR and the relationship with clinicl pathological factors and their interrelationships.Results There was significant correlation between the expression of Twist mRNA and the degree of differentiation[high and middle differentiation 93.33％(14/15),1ow differentiation 53.33％(8/15)],lymphatic invasion[yes 93.75％(15/16),no 50.00％(7/14)]and TNM staging[Ⅰ-Ⅱ?stage 46.15％(6/13),III-Ⅳ?stage 94.12％(16/17)]in breast cancer tissue(P＜0.05),while there was no obvious correlation between the expression of Twist mRNA and the age,tumor diameter,adventitial infiltration,estrogen receptor,progesterone receptor(P＞0.05).The expression of Twist and p53 mRNA in breast cancer tissue were significantly higher than those in adjacent noncancerous tissue and normal breast tissue[(112.36±12.53)％ vs.(101.37±9.12)％ and(98.03±9.04)％,(101.73±13.32)％ vs.(91.43±7.43)％ and(90.83±6.58)％,P＜0.01],while the expression of E-cadherin mRNA in breast cancer tissue was significantly lower than that in adjacent noncancerous tissue and normal breast tissue[(55.43±12.49)％ vs.(69.39±5.63)％ and(72.73±7.93)％,P＜0.01],there was no significant difference between adjacent noncancerous tissue and normal breast tissue(P＞0.05).The expression of Twist mRNA in breast cancer tissue was positively correlated to the expression of p53 mRNA(r=0.526,P=0.004),and negatively correlated to the expression of E-cadherin mRNA(r=-0.500,P=0.000).Conclusions Twist and p53 in breast cancer tissue show higher expression,while E-cadherin shows lower expression.Twist can promote invasion,metastasis of breast cancer by up expression of p53 and down expression of E-cadherin,and it plays an important role.

Objective To investigate the effect of different head flexion/extension angles on static sitting balance in normal youth. Methods34 selected healthy college students were measured with the track length of the centre of gravity under eyes closed, head in a neutral position,flexed in 15°, 30°, 45°, and extended in 15°, 30° (30 s each position). Results the average length from small to big were: head flexedin 30°, neutral position, flexed in 15°, flexed in 45°, extended in 15°, extended in 30°. There was no significant difference among the averagelength when head flexed in 30°, in neutral position and flexed in 15° (P>0.05). Conclusion The static sitting balance is the most whenhead put in neutral position to flexed in 30°, and worst in extended in 30° in healthy youth.

BACKGROUND:The resin infiltration technique for masking white spot lesions has obtained a result superior to the conventional remineralization. Up to now, few studies have evaluated the color of carious incipient lesions treated with the resin infiltration.
OBJECTIVE:To assess the color change of caries incipient lesions in the enamel treated with resin infiltration.
METHODS: Forty-eight extracted teeth were exposed to demineralizing solution for 4 weeks to establish artificial caries models. Then artificial caries models were treated with resin infiltration and randomized into four groups: these specimens were immersed in red wine, coffee, tea and artificial saliva for 2 and 4 weeks, respectively. The base line color was evaluated by spectrophotometer. The variation in color (ΔE) was analyzed by one-way analysis of variance and Tukey’s tests.
RESULTS AND CONCLUSION:Al specimens underwent color and lightness changes, irrespective of immersion media. After 2 weeks of immersion, ΔE values were ranked as folows: red wine > coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05). After 4 weeks of immersion,ΔE values were ranked as folows: red wine≈ coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05) but not between the red wine and coffee groups (P > 0.05). Significant changes in the color were found in the red wine and coffee groups at different time after immersion (P < 0.05). Immersed in red wine, coffee and tea, the?E value was > 3.7, which is not acceptable in clinic. These findings indicate that the color stability of carious incipient lesions located in the enamel treated with resin infiltration is associated with the soak solution and soak time. In addition, immersion in red wine and coffee results in significantly increased color alteration (ΔE) compared with the artificial saliva.
