Objective To compare clinical efficacy of clobetasol propionate ointment and vitamin A acid cream in the treatment of skin papule type amyloidosis.Methods 100 cases of skin papule type amyloidosis were randomly divided into the observation group and control group,each had 50 patients.The control group was treated with Vitamin A acid cream while the observation group used clobetasol propionate ointment for treatment.Skin lesion area,infiltration,skin color,skin itching score as well as the cure rate and efficiency were compared after 4 weeks of treatment.Results The two groups' symptoms was improved,symptom scores was decreased gradually after treatment than before,the observation group's symptom scores at 1,2,3,4 weeks were (9.35 ± 1.88),(6.54 ±2.16),(4.08 ±1.32),(2.04 ± 0.95) points which was significant better than (10.86 ± 2.08),(7.98 ± 2.57),(6.25 ± 1.44),(4.56 ± 1.18) points of the control group,the difference of two groups was statistically significant (t =6.22,6.71,7.30,7.41,all P ＜ 0.05) ;4 weeks after treatment,the observation group's efficience and cure rates were 94％ and 34％,significantly higher than 70％ and 22％ of the control group,the difference was statistically significant (x2 =9.040,8.391,all P ＜ 0.05).Conclusion Clobetasol propionate ointment has a exact effect in treatment of skinpapule type amyloidosis than vitamin A acid cream,which is worthy of clinical application.

OBJECTIVE:To establish a turbidimetric method for the determination of the potency of the crude drugs and tablets of oxytetracycline. METHODS: By turbidimetric method in which Staphylococcus aureus was used as the test organism with biomass concentration of 1.0%～1.5% (V/V). The culture temperature was 37 ℃ and the culture time was about 4 h. The method was compared with the cup-plate method in potency. RESULTS: The linear range of oxytetracycline was 0.05～0.4 IU?mL-1. The average recovery of the crude drug of oxytetracycline was 99.59% (RSD=2.0%) and that of oxytetracycline tablets was 99.51% (RSD=1.91%), showing no significant difference as compared with the cup-plate method in contents. CONCLUSIONS: The method was sensitive and rapid yet with few influencing factors thus applicable for the determination of the potencies of oxytetracycline and its tablets.

OBJECTIVE:To determine the titer of main component in kitasamycin tablets and acetylkitasamycin dry suspension.METHODS:Staphylococcus aureus was used as test organism and which were cultured at (37?0.5) ℃ for about 4～5 hours by adding 1.0%～1.5% kitasamycin and 2.0%～2.5% acetylkitasamycin,then the absorbance was determined at a wavelength of 530 nm.RESULTS:The linear range of kitasamycin was 0.5～4.0 IU?mL-1 and that of acetylkitasamycin was 0.45～6.3 IU?mL-1,and their recovery rates were 101.7%(RSD=1.9%,n=9) and 101.1%(RSD=2.1%,n=9),respectively.CONCLUSION:The established turbidimetry is sensitive,rapid yet with few influencing factors,thus it is applicable for the titer determination of main component in kitasamycin tablets and acetylkitasamycin dry suspension.

OBJECTIVE: To develop a rapid, accurate and sensitive method for the determination of nifedipine, nitrendipine and nimodipine which were added into traditional patent medicine illegally. METHODS: The LC-MS method was used to detect the extractive of Chinese patent medicine for antihypertension in respects of relative molecular mass, tandem mass spectrometry fragment, retention time, UV spectrum. The compounds added into the Chinese patent medicine were identified by comparing with standard sample in terms of spectrum, chromatographic and mass spectrometric behavior. RESULTS: According to four aspects of determination, nifedipine, nitrendipine and nimodipine were found in three kinds of Chinese patent medicine for antihypertension. CONCLUSION: The method is selective and sensitive for the detection of nifedipine, nitrendipine and nimodipine which were added into traditional patent medicine illegally.

Objective To analyze and identify the mutations of ATP6V0A4 and ATP6V1B1 gene in autosomal recessive distal renal tubular acidosis (rdRTA) children,and study the association of genotype and phenotype. Methods Genome DNA was amplified by PCR.Mutations of ATP6V0A4 and ATP6V1B1 gene in 3 children from 3 families were examined by direct sequencing.One hundred unrelated healthy subjects were selected to evaluate all mutations found in this study. Results A novel homozygous nonsense mutation was identified in ATP6VOA4 gene in one child, and a novel heterozygous nonsense variant and a frame-shift alteration were found in another child.No mutation of both genes was found in the third child.Conclusions Study of mutant genes of rdRTA in Chinese patients is helpful to understand the association in genotype and phenotype and increase the level of cognition and treatment to this disease.

Objective To investigate the vessel structure changes of carotid artery with age in normal adults with a newly-developed 3-dimensional ultrasound imaging modality.Methods One hundred and twenty-five normal adult volunteers were divided into five groups:group A,20-29 years old,25 cases;group B,30-39 years old,27 cases;group C,40-49 years old,28 cases;group D,50-59 years old,23 cases;group E,older than 60 years old,22 cases.The straight sections of common carotid arteries were scanned by full-volume three-dimensional ultrasound probe.With a vessel plaque quantification software (VPQ),the following parameters were obtained:intima-media thickness (IMT),vessel total area (VTA),vessel lumen area (VLA),vessel wall area (VWA),and normalized wall index (NWI).Results IMT,VTA,VWA,VLA and NWI were all positively correlated with age (r =0.79,0.48,0.77,0.27 and 0.67 respectively,P =0.00),and there was significant difference among age groups (P ＜0.01).IMT,VTA,VWA increased with age gradually whereas VLA increased only in group E and NWI showed no significant difference between group E and D.VWA and VTA of males were significantly greater than those of females in group A,B and C,and VLA of males was significantly greater than females in group A and B.There was no significant difference in IMT and NWI between gender groups.Conclusions Age is an important factor to carotid remodeling,and IMT,VTA and VWA increase with age,but VLA keeps constant in people under 60-year-old while NWI becomes stable in people over 50-year-old.It is essential to consider the physiological changes of carotid with age when pathophysiological process of atherosclerosis is involved.

Objective To investigate the inhibitory effect of silencing survivin gene with siRNA on the growth of gastric cancer cells and its mechanism,and provide evidence in treatment for gastric cancer.Methods DNA template coding survivinspecific siRNA was designed and synthesized.Two recombinant plasmids (pGCsilencerU6/GFP/survivin-siRNA-1 and-2) were constructed.The gastric carcinoma cel1 line SGC-7901 were divided into three groups: liposome-treated control group,empty plasmid-transfected control group and survivin-siRNA-1 transfected group.In order to observe the effect of survivin-siRNA,the expressions of survivin mRNA and protein were detected by RT-PCR and Western blotting,respectively.Methyl thiazolyl tetrazolium(MTT) assay was applied to determine the cell growth status.Apoptotic rates were evaluated by flow cytometry(FCM).Results The results of Western blotting and RT-PCR indicated that the inhibitory rates of protein and mRNA in pGCsilenerU6/GFP/survivin-siRNA-1 transfected group(78.25% and 88.75%) were higher than those in liposome-treated control group(5% and 2%) and empty plasmid-transfected control group(1% and 6%)(P
