OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.

METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.

RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).

CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.

BACKGROUND:The position of median and radial nerves corresponding to elbow is usual y estimated by macroscopical measurements, but there are big data errors when the elbow is bent. OBJECTIVE:To measure and analyze the impacts of elbows in different positions on median and radial nerves under X-ray. METHODS:Ten fresh frozen upper limb specimens were selected. The distance of median and radial nerves to the osseous marks inside the elbow was measured when the elbow was in extension, extension-half pronation, bent at flexion 90 degrees and bent at 90 degrees with the injection of normal saline into the joint capsule, respectively. RESULTS AND CONCLUSION:The positions of median and radial nerves were not influenced when the elbow was in extension or in extension-half pronation (P>0.05). The distance of median and radial nerves to the osseous mark of the elbow was significantly lengthened when the elbow was moved from from extension to was bent at 90 degrees (P<0.05). The intra-articular injection of normal saline when the elbow flexion 90 degrees significantly elongated the distance of median and radial nerves to the osseous mark of elbow (P<0.05). These results suggest that the elbow in different positions can induce the displacement of median and radial nerves. In addition, the distance between median, radial nerves and the osseous marks of the elbow is obviously lengthened when the elbow is in flexion with intra-articular injection of normal saline.

OBJECTIVETo observe the therapeutic effect of Wenshen Huatan Recipe (WHR) on patients with early or middle stage chronic renal insufficiency (CRI) and investigate the clinical validity of applying sputum and blood stasis theory in treating CRI.

METHODSSixty CRI patients were selected and randomly assigned to the treated group (n = 32) and the control group (n = 28), all received conventional and symptomatic treatment, but those in the treated group were given WHR additionally. Two months were taken as one treatment course and the study lasted for 3 treatment courses. Total effective rate was assessed at the end of the 2nd and 6th month, changes of clinical symptom scores of TCM, and levels of blood urea nitrogen (BUN) and serum creatinine (SCr) in the two groups were observed as well.

RESULTSThe total effective rate of the 2nd and 6th month was 68.8% and 75.0% respectively in the treated group and 42.9% and 35.7% in the control group respectively, the difference between the two groups was significant (P < 0.05). Symptoms were improving along with the increasing medication time, and the improvement between the two groups was significant (P<0.01). Levels of SCr and BUN were significantly lowered in the treated group after 2-month and 6-month treatment (P < 0.05, P < 0.01).

CONCLUSIONWHR can significantly improve the clinical effect of treatment on CRI during early-middle stage, suggesting that CRI could be treated based on sputum and blood stasis theory with definite clinical efficacy.

Objective To observe the effect of early goal directed therapy (EGDT) on tissue perfusion,microcirculation and tissue oxygenation in patients with septic shock.Methods A prospective observational study was carried out in 20 patients with early septic shock admitted to ICU within 24 hours after onset.Patients with one of following conditions,including stroke,brain injury,other types of shock,severe heart failure,acute myocardium infarction,ages below 18,pregnancy,terminal stage of disease,cardiac arrest,extensive bums,mouth bleeding,oromandiblular dyetonia (difficult to open the mouth),and the time elapsed over 24 hours after onset of septic shock,were excluded.The eligible patients were treated with the standard procedure of EGDT.The partial pressure of transcutaneous oxygen and carbon dioxide (PtcO2,PtcCO2) was monitored and hemodynamic data were recorded.Sidestream dark field imaging device was applied to detect the sublingual microcirculation.Hemodynamics,tissue oxygen,and sublingual microcirculation were compared before treatment and after EGDT.When the variables met the normal distribution,t test was applied.Otherwise,Wilcoxon test was used.Correlation between variables was analyzed with Pearson Correlation Analysis.Results Of 20 patients,19 met all 4 elements in criteria of EGDT after treatment and were eligible for study.PtcO2 and PtcCO2 were monitored in 19 patients.Sublingual microcirculation was obtained in four of them.(1) After the criteria of EGDT were entirely met,PtcO2 increased from (62.7 ± 24.0) mm Hg to (78.0 ± 30.9) mm Hg (P ＜ 0.05) ; tissue oxygenation index (PtcO2/FiO2) was (110.7 ± 60.4) mm Hg before treatment and (141.6 ± 78.2) mm Hg after EGDT (P ＜ 0.05).PtcCO2 and PaCO2 gap (difference between PtcCO2 and PaCO2) decreased significantly after EGDT (P ＜ 0.05).(2) Both proportion of small vessels with perfusion (PVP) and microcirculatory flow index of small vessels (MFI) showed a trend of increase after EGDT,but there were no significant differences between pre-and post-EGDT (P was 0.051 and 0.074 respectively).(3) PtcO2,PtcO2/FiO2,and PtcCO2 were not linearly related to central venous saturation,lactate,oxygen delivery,and oxygen consumption (All P ＞ 0.05).Conclusions Peripheral perfusion improved after EGDT in patients with septic shock but those hemodynamic variables might not exactly reflect the authenticity of global perfusion.

Objective To evaluate the effects of domestic irbesartan on blood pressure and renal function in the aged with primary hypertension.Methods Renal function,plasma and urine β2 microglob ulin WBS measured and blood pressure was investigated by 24-hour ambulatory blood monitoring in 42 aged with primary hypertension who received domestic irbesartan(1 50 mg/d,followed up every 1-2 weeks.If the effect was not ideal,the dose could be added to 300 mg/d)in 8-week's treatment.Results After the treatment.24 hours recall systolic blood pressure,24-hour mean diastolic blood pressure,mean day systolic blood pressure,mean day diastolic blood pressure,mean night systolic blood pressure,mean night diastolic blood pressure were significantly reduced.At the same time,domestic irbesartan induced a remarkable reduction of plasma and urine β2 microglobulin [(5.9±3.3)μg/L vs(2.6±2.6)μg/L, (811.2±97.2) mmol/L vs(457.6±69.8)mmol/L,respectively].Conclusion The antihypertensive effects of domestic irbesartan can persist for 24-hour and Can reduce urinary protein.

Objective To explore the effects of beta-amyloid precursor protein (APP17) peptide on the changes in the expressions of phosphoinositide 3-kinase(PI3K), protein kinase B(PKB) and phosphorylation of cAMP response element binding protein (p-CREB) in the neurons of hippocampal gyms in rats after cardiopulmonary resuscitation. Method Twenty-one Wistar rats were randomly divided into three groups, namely the sham-operated control group, the resuscitation group and resuscitation with APP17 peptide-treated group. The rat model of asphyxial cardiac arrest was made by clamping the endotracheal tube and the standard external cardiopulmonary resuscitation ( CPR) was performed until the restoration of spontaneous circulation ( ROSC) observed.ROSC was defined by the appearance of normal QRS waves of electrocardiogram and mean artery pressure ( MAP)≥60 mmHg for more than 10 minutes. Rats of resuscitation group and control group received intravenous 0.9%NaCl, and the rats of the APP17 peptide group were treated with APP17 peptide(10μg·300 g~(-1), i. v.) after ROSC. Rats were sacrificed by decapitation after reperfusion 2 hours and then the cerebral hippocampal gyrus was immediately separated to detect PI3K, PKB and p-CREB by immunohistochemistry ( IHC) and Western-blot analysis. Statistical comparisons were made by one-way analysis of variance (ANOVA) . Results IHC showed that there was no significant difference in PDK positive cells between resuscitation group and control group (2.75 ±1.80 vs. 2.53 ± 1.53, P > 0.05) . The PDK obviously more increased in the APP17 peptide group than in resuscitation group(5.85 ± 2.83 vs. 2.75 ± 1.80, P < 0.01) .The counts of PKB and p-CREB positive cells were obviously lower in resuscitation group than those in control group (2.45 ± 1.36 vs. 5.22 ± 2.50, P < 0.05);(2.41 ± 1.11 vs. 8.31 ±3.02, P < 0.01 ). The PKB and p-CREB positive cells were significantly higher in the APP17 peptide group than in resuscitation group (9.66±4.32 vs. 2.45 ±1.36, P < 0.01);(14.18 ± 3.96 vs.2.41 ± 1.11, P <0.01). The PKB and p-CREB protein levels in resuscitation group were lower than those in the control group. Conclusions The expressions of PKB and p-CREB in neurons of hippocampus gyrus 2 hours ROSC, and APP17 peptide could restorer the expression of PDK, PKB and p- CREB and thereby protect the neurons of hippocampus gyrus from the injury of CPR.
