Enamel hypoplasia is a surface defect of the tooth crown caused by a disturbance of enamel matrix secretion.Enamel hypoplasia may be inherited,or result from illness,malnutrition,trauma,or high concentrations of fluorides or strontium in the drinking water or food.Different types of enamel hypoplasia have been distinguished,such as pit-type,plane-type,and linear enamel hypoplasia.Hypoplasia has been related to the intensity and duration of stress events,the number of affected ameloblasts,and their position along the forming tooth crown.Amelogenesis imperfecta(AI) is a heterogeneous group of inherited defects in dental enamel formation,most teeth are affected in both the primary and permanent dentition.The malformed enamel can be unusually thin,soft,rough and stained.The strict definition of AI includes only those cases where enamel defects occur in the absence of other symptoms.Currently,there are seven candidate genes for AI: amelogenin,enamelin,ameloblastin,tuftelin,distal-less homeobox 3,enamelysin,and kallikrein 4.Since the enamel is formed according to a strict chronological sequence,and once formed,undergoes no repair or regeneration.Then the analysis the phenotype of enamel hypoplasia can provide insights of the severity of inherited or environmental stress and the molecular mechanism during the period of enamel formation.

Objective:To investigate the expression and distribution of aquaporin 5(AQP5) in allergic rhinitis(AR)treated by fluticasone propionate and levocabastine.Method:Forty Wister rats were divided randomly into AR(n=30) and control groups(n=10). After AR models were established, the AR rats were divided evenly into F group, L group and AR control group.Three groups were treated respectively for 28 days, then the expression of AQP5 in nasal mucous membrane were detected by immumohistochemistry assay.Result:The distribution of AQP5 was consistent in all groups. The expression of AQP5 in F group was significantly different from L group and AR group (P < 0.05), while there was no significant difference between that of AR group and L group(P>0.05). The expression of AQP5 in L group was significantly different from that in control group(P<0.05).Conclusion:High expressions of AQP5 in rat with AR indicated the positive correlation between AQP5 and AR. AQP5 might be one of pathological factors of AR concered with gland's excessive secretion and tissue edema. Glucocorticoid can down-regulate the expression of AQP5,but H1-receptor antagonist can not reduce the expression of AQP5.

OBJECTIVE To estimate the value of Mycoplasma pneumoniae(Mp)-IgM,C-reactive protein(CRP) and WBC on diagnosis of children respiratory infection.METHODS Serum Mp-IgM antibody,CRP and WBC were tested in 225 children with respiratory infection by passive particle agglutination,ITM immunoturbidimetry and analyzer of blood cell.RESULTS Forty-six cases of 225 children were identified positive in Mp-IgM.The positive rate of Mp-IgM was 20.4%.Compared the CRP and WBC among cases positive in Mp-IgM,bacterial infected and virus infected,there was significant difference bewteen cases positive in Mp-IgM and bacterial infected,no significant difference bewteen cases positive in Mp-IgM and virus infected.CONCLUSIONS The joint detection of serum Mp-IgM antibody,CRP and WBC can be a valuable clue to diagnosis of children respiratory infection.

The property theory of Chinese herbal medicine (CHM) is regarded as the core and basic of Chinese medical theory, however, the underlying mechanism of the properties in CHMs remains unclear, which impedes a barrier for the modernization of Chinese herbal medicine. The properties of CHM are often categorized into cold and heat according to the theory of Chinese medicine, which are essential to guide the clinical application of CHMs. There is an urgent demand to build a cold/heat property classification model to facilitate the property theory of Chinese herbal medicine, as well as to clarify the controversial properties of some herbs. Based on previous studies on the cold/heat properties of CHM, in this paper, we described a novel strategy on building a cold/heat property classification model based on herbal bio-effect. The interdisciplinary cooperation of systems biology, pharmacological network, and pattern recognition technique might lighten the study on cold/heat property theory, provide a scientific model for determination the cold/heat property of herbal medicines, and a new strategy for expanding the Chinese herbal medicine resources as well.

Objective: To find out the relationship between the use of different dosages of mannitol and the changes of cerebral blood flow in patients with stroke at the peak of edema formation. Methods: Twenty-eight patients with hemispheric stroke were treated with 20% mannitol solution for reduction of increased intracranial pressure, at the dosages of 125 ml or 250 ml. Transcranial Doppler was used to monitor the blood flow of the bilateral middle cerebral arteries before and after the treatment. The monitoring parameters included peak systolic velocity (Vs), end diastolic velocity (Vd), mean velocity (Vm), and pulsatility index (PI), and percentage rate (PR) of change in each parameter. At the same time, the blood pressure of brachial artery was monitored. Results: Vs, Vd, and Vm on the affected and unaffected sides were improved significantly in patients using 125 ml mannitol. The PI on the affected sides decreased markedly (P = 0.002, P = 0.028) from 45 min to 60 min; the PI on the unaffected sides did not decrease significantly (P > 0.05); there were no significant differences in the PR of Vs, Vd, Vm and PI on both sides (P > 0.05). Vs, Vd, and Vm on the affected and unaffected sides were improved fluctuatly in patients using 250 ml mannitol. The PI on the affected sides did not decrease markedly (P > 0.05 ); the PI on the unaffected sides decreased significantly (P = 0.005) 60 min after mannitol infusion; the PR of PI at 60 min had significant difference between two sides (P = 0.006). The peaks of the velocity of blood flow increasing and PI decreasing on the affected sides occured later than that on the unaffected sides in patients both using 125 ml and 250 ml mannitol. Conclusion: The improvement of cerebral hemodynamics on the affected sides is more significant than that on the unaffected sides with 125 ml mannitol, and the improvement of cerebral hemodynamics on the unaffected sides is more significant than that on the affected sides with 250 ml mannitol.

Objective To investigate the efficacy of patient-controlled epidural analgesia(PCEA)with ropivacaine plus fentanyl for postoperative analgesia after suprapubic prostatectomy(SPP).Methods Thirty-six ASAⅡorⅢpatients aged 62-78 yrs weighing 52-84 kg undergoing SPP were randomly divided into 3 groups with 12 patients in each group:groupⅠreceived PCEA with 0.12% ropivacaine and fentanyl 1?g?ml~(-1);groupⅡreceived PCEA with 2% ropivacaine and fentanyl 1?g?ml~(-1) and groupⅢreceived patient-controlled intravenous analgesia(PCIA)with morphine 0.2 mg?ml~(-1).Postoperative pain was assessed using VAS(0=no pain,10= worst pain).The degree of motor blockade(modified Bromage scale)was evaluated at 6,24,48 and 72 h after operation(T_(1-4)).Bladder spasm episodes were recorded.Side effects including nausea,vomiting and pruritus and the total number of RBC in rinse solution were also recorded.Results(1)Bromage score(0=no motor block,3 =inability to flex ankle joint)was significantly higher in groupⅠandⅡthan in groupⅢat T1(6 h after op.), but significantly lower in groupⅠandⅢthan in groupⅡat T_(2-4)(24-72 h after operation).(2)VAS score(0= no pain,10=worst pain)was not significantly different among the 3 groups without bladder spasm but significantly higher in groupⅢthan in other 2 groups during episodes of bladder spasm.(3)The number of bladder spasm episodes was not significantly different among the 3 groups within 6h after operation,but was significant larger in groupⅢthan in the other two groups during 6-72 h after operation.During 6-24 h after operation more bladder spasm attacks occurred in groupⅠthan in groupⅡ.(4)The incidence of side effects was significantly lower and the total number of RBC in rinse solution was significantly smaller in groupⅠandⅡthan in groupⅢConclusion PCEA with 0.12% or 2% ropivacaine plus fentanyl can effectively reduce the number of bladder spasm attack and postoperative bladder bleeding.Different concentrations of ropivacaine should be used for PCEA during different postoperative periods.
