To obtain the caries experience and, plaque accumulation severity and pit and fissure morphology in first permanent molars in 7-8 children in Wuhan, as a reasonable prediction of caries risk and preventive attention in the future, a convenient sample of five primary schools in the vicinity of the Wuhan University School and Hospital of Stomatology was drawn. Two calibrated examiners orally examined all present grade 2 children in the classroom, using standard caries plaque and tooth morphology criteria. Dental caries was scored at enamel (D(2)) and dentine (D(3)) for tooth and surface level. Independent variables were age, gender and school. Data analysis used analysis of variance and t-test. The sample comprised 1 043 7- and 8-year-olds. The prevalence of dental caries in permanent dentition was 8.7% and in primary dentition, 68.7%. Mean Decayed, Missing, Filled Teeth/S (DMFT/S) scores were 0.11 and 0.14, respectively. Mean dmft/s scores were 2.8 and 5.0. The d-component constituted 75% of the d(3)mft index, while enamel carious lesions constituted 36% of the total number of carious lesions (d(2,3)-component). Prevalence of medium and deep pits and fissures was 84.6%. Prevalence of medium and severe plaque accumulation was 67.4%. Prevalence of dental caries in the deciduous and permanent dentitions of 7- to 8-year-old children was high. Deep pits and fissures in high caries risk children should be sealed.

Objective To investigate short-term hemodynamic changes in selected patients with middle cerebral artery(MCA) stenting by transcranial Doppler sonography(TCD).Methods Stenting was given to 29 cases (31 MCAs) of patients with moderate and severe MCA stenosis if they had recurred symptoms during the standard antiplatelet therapy.TCD was applied to assess the hemodynamic changes in the stenosis segment and stenotic distal segment before stenting, 1 h and 3 d after stenting. Results Angiography showed that the rate of post-procedure residual stenoses of MCA were less than 20%.Compared with the pre-stentinng peak systolic velocity [PSV, (273±77)cm/s], the post-stenting PSV significantly decreased,which was (162±38) cm/s (P<0.01) at 1 hour and (168±45)cm/s ( P<0.01)at 3 days, respectively.Three cases (3 MCA) experienced recurrent stenosis-like spectra at stenosis segments 3 d after stenting and brain CT showed that 2 out of 3 cases suffered intracranial hemorrhage,which was potentially induced by hyperperfusion; PSV doubled in the stenotic distal segment in at least 28.6% patients.There was no statistic difference between pre- and post-stenting in the contralateral MCA (P>0.05).Conclusions Stenting can dramatically improve the hemodynamic compromise of stenosis segments and their distal segments in selected patients with symptomatic MCA stenosis, however, potential hyperperfusion risk might he taken into consideration after MCA stenting.

Objective To test the effect of bone marrow mesenehymal stem cells (MSCs) transplantation on oxidative stress and the development of pulmonary emphysema in rats. Methods SD rats (n=26) were randomly divided into three groups:normal control group (group A, n=8),emphysema group (group B, n=8) and emphysema+MSCs transplantation group (group C, n=10).Rat models of emphysema was established by exposing rats to cigarette smoking for 14 weeks. Then rats of group C received MSCs transplantation. At the 14th and 28th days after 4 course of MSCs transplantations, one rat in group C was sacrificed at each time point and their lungs were preserved in frozen sections. Survival of MSCs in the lung tissues were observed by fluorescence microscopy. Eight weeks after transplantations, lung sections were stained by hematoxylin and eo?sin (HE) to observe the morphological alterations.Mean linear intercept (MLI) and mean alveolar numbers (MAN) were also measured. Serum and lung malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity were also examined. Re?sults At the 14th day and 28th day after transplantations of MSCs, MSCs successfully localized to lung and survived in rat models of emphysema. Emphysematous changes of lung tissues were observed in both group B and group C. MLI was higher while MAN was lower in group B and C than those in group A (P<0.05). MLI and MDA levels in serum and lung were high?er while MAN level and SOD activity were lower in group B than those in group C (P<0.05).MDA levels in serum and lung was higher while SOD activity was lower in group B and C than those in group A (P<0.05). Conclusion MSCs transplanta?tions can effectively alleviates pulmonary emphysema in rat models which might through reducing oxidative stress .

OBJECTIVETo evaluate the clinical efficacy and side effects of Shelian capsule (SLC) as adjuvant of embolismic chemotherapy on primary hepatic carcinoma.
METHODSOne hundred and twenty patients with hepatic carcinoma were conducted arterial embolismic chemotherapy with FAM program for two therapeutic cycles. The 60 patients in the treated group were taken SLC orally for auxiliary treatment, and the other 60 in the control group were given glucurolactone instead. The tumor size, Karnofsky score, clinical symptoms, alpha fetoprotein (AFP), NK cell, T cell-subgroup and adverse effect before and after treatment between the two groups were compared respectively.
RESULTSAs compared with the control group, in the treated group the Karnofsky score was better ((P < 0.05) and the remission rate of clinical symptom were superior (66.7% vs 88.3 %, P < 0.05). The ratio of CD4/CD8 and NK cell activity was significantly different between the two groups (P<0.05). There was no obvious adverse effect in the treated group.
CONCLUSIONSLC can effectively enhance the immunity of patients with tumor, remit clinical symptoms, improve quality of life and without any side effects.
