3.Titanium versus polymethyl methacrylate resin complete denture base A phonology evaluation
Chinese Journal of Tissue Engineering Research 2010;14(42):7976-7980
BACKGROUND: Several studies have demonstrated that the range,thickness and morphology of oral prosthesis directly influence patient's phonetic function,and titanium base and polymethyl methacrylate(PMMA)resin base yield different influences on phonetic function due to different thicknesses of materials.OBJECTIVE: To analyze the phonetic parameters in one complete denture patient who wear titanium base and PMMA resin base simultaneously and investigate the influences of maxillary complete denture base on phonetic function.METHODS: Through the use of computer-based voice analysis software PRAAT4.4.34,frequency value of the first concentrated frequency area when speaking consonant sounds/x,sh,r,zh,ch,j,q/and voice onset time when speaking consonant sounds/g,k,zh,ch,j,q/were statistically analyzed in the same patient who separately wear titanium complete denture base and PPMA resin complete denture base,and spectrogram of velar stops between complete denture bases was compared.RESULTS AND CONCLUSION: MMPA resin complete denture base was to some extent poor in promoting the recovery of phonetic function owing to great base thickness.Titanium complete denture base with less thickness in the tongue or palate region would help recovery of phonetic function.Extraction and analysis of phonological parameters,such as frequency value of first concentrated frequency area and voice onset time,using CSL computer*based voice analysis system,would provide objective evidence for lamprophony analysis after wearing complete denture.Maxillary denture with thinner base in tongue and palate regions better promotes the recovery of patient's phonetic function.

Chinese Journal of Minimally Invasive Surgery 2017;17(3):202-205
Objective To investigate the relevant factors of early stage hyponatremia in patients with complete cervical spinal cord injury (CSCI). Methods A retrospective study was conducted in consecutive 49 individuals with complete CSCI from January 2010 to December 2015.The diagnostic criteria for hyponatremia was two consecutive tests (interval <24 h) of serum sodium <135 mmol/L.Twenty-six patients with hyponatremia were classified as hyponatremia group , and the other 23 patients without hyponatremia were classified as control group .Ten factors were included in the univariate analysis: age, gender, the highest level of CSCI , the degree of CSCI , the blood albumin when transferred to ICU , the serum sodium when transferred to ICU , the use of glucocorticoid , the incidence of neurogenic shock , the average daily urine output , and the average daily liquid balance .The variables with significance (P<0.05) in the univariate analysis then entered stepwise logistic regression analysis .The optimal critical point of the continuous variables with statistical significance in the univariate analysis was determined by drawing the receiver operator characteristic curve . Results There were differences in two variables between the two groups ( P<0.05 ) .The incidence of neurogenic shock before the occurrence of hyponatremia was 57.7% ( 15/26 ) in the patients with hyponatremia and 26.1% ( 6/23 ) in the patients without hyponatremia(χ2 =6.516,P=0.011).The average daily urine output was (2225 ±389) ml in the patients with hyponatremia and (1936 ±289) ml in the patients without hyponatremia (t=2.924,P=0.005).The stepwise logistic regression analysis indicated that these two factors may be the independent relevant factors (OR =13.708 and 0.996, P =0.004 and 0.002, respectively).The receiver operator characteristic curve demonstrated the average daily urine output more than 2331 ml was the optimal critical point . Conclusion The neurogenic shock and the average daily urine volume more than 2331 ml are the independent relevant factors of early stage hyponatremia in patients with complete CSCI .

Objective: To explore the effect of initial lower PO_2 controlled reperfusion on cyanotic hypoxic immature myocardium protective during post-ischemia reperfusion. Methods: 24 hypoxic neonatal rabbits were randomized into 3 groups (8 in each group). Group I (initial lower PO_2 controlled reperfusion), group II (normal PO_2 controlled reperfusion), group III (high PO_2 reperfusion group). Using isolate heart Langendorff ischemia-reperfusion model, the myocardial protection results were observed and the mechanism were discussed from molecular biological and ultrastructural view. Results: Compared with high PO_2 reperfusion group and normal PO_2 reperfusion group, the products of oxygen free radical were lowered at the end of reperfusion in initial lower PO_2 controlled reperfusion group. ATP content was increased, myocardial contractility was elevated, coronary sinus flow was raised, the degree of myocardium edema was reduced, and ultrastructure alteration was lessened significantly. Conclusion: Initial lower PO_2 controlled reperfusion reduces oxygen free radical injury, enhances myocardial energy metabolism, lessens myocytic structure destruction and improves postischemic function recovery of cyanotic myocardium.

As the actual clinical reflecting of transform Chinese medicine special curative effect, Chinese medicine preparation not only satisfies the need of hospital clinic, scientific research and teaching, but also plays an important role in deepening medical and health system reform, improving people's health level and contributing to the economic growth. However, some problems about administration and approval (tending to western medicine), contraction of the scale, lack of synchronization for clinic and scientific research, and the imbalance of regional development make Chinese medicine preparation move forwards slowly in contradiction. It has not only reduced the effectiveness of the Chinese medicine preparation in hospital clinic, but also brought bad effect on modernized development of Chinese medicine preparation. Research shows that main influencing factors of status quo of Chinese medicine preparation in medical institution include imperfect laws and regulations, high cost than income, and shortage of talents in preparation research. The analysis indicated that the necessary measures to break the contradiction, improve clinical effect of Chinese medicine, and promote the modernization development of Chinese drugs preparation were as follows: government and related departments should strengthen the supporting force in policy by adjusting the examination and approval policy, speeding up dispensing use, reforming pricing system, including into medicare reimbursement, integrating advantage resources and so on; medical institution should actively carry out research and development of traditional Chinese Medicine through drawing the traditional and modern essence, reserving professional talents, and developing characteristic preparation; companies cooperate with hospitals for complementary advantages, which can rapidly transform Chinese medicine preparation into clinical practice.

OBJECTIVE To investigate the effect of norepinephrine (NE) on expression of interleu?kin-6 (IL-6) in human macrophages and explore its pro-inflammatory and pro-atherosclerotic mecha?nisms. METHODS Murine U937 macrophages were cultured and stimulated with 0.01-10μmol·L-1 of NE for 6, 9, 12, 24 and 48 h. The IL-6 mRNA level of 24 h was analyzed by RT-PCR, and IL-6 protein expression in the supernatant at 0, 6, 9, 12, 24 and 48 h was detected by ELISA. After 24 h, intracellular reactive oxygen species (ROS) generation was observed by DCF fluorescence. The cells were pretreated with antioxidant N-acetylcysteine (NAC), complexⅡinhibitor thenoyltrifluoroacetone (TIFA) and NADPH oxidase inhibitor diphenyleneiodonium (DPI) for 1 h, and stimulated with different concentrations of NE for 24 h, before the level of IL-6 protein was detected by ELISA. RESULTS The expression of IL-6 mRNA and protein increased with the concentration NE 0.01-10 μmol · L-1 and incubation time. IL-6 mRNA and protein levels in macrophages were 2.62 and 4.47-fold those in cell control group when treated with NE 1.0μmol·L-1 for 24 h. Meanwhile, as the concentration of NE increased, the generation of ROS was 1.87, 2.56, 2.91 and 5.36-fold that of cell control group (P<0.01). NAC 10 mmol · L-1 and DPI 10 μmol · L-1 significantly antagonized the effect of NE on IL-6 expression, but TIFA had no effect. CONCLUSION NE upregulates IL-6 expression, which may contribute to the formation and develop?ment of atherosclerosis via ROS mediated by NADPH oxidase in macrophages.

BACKGROUND:Precision attachment has been widely used in complete denture because of its strong retention, good appearance, comfort and durability. Among them, magnetic attachment and bal-cap attachment are commonly applied for mandibular complete denture.
OBJECTIVE:To compare the clinical effects of magnetic attachment, bal-cap attachment and traditional clasp retainer used in the mandibular removable partial denture.
METHODS:A total of 45 patients with dentition defects were included in this study, they were treated with magnetic attachment, bal-cap attachment and traditional clasp retention of mandibular removable partial denture. Fifteen patients received one means. The satisfaction of patients and the periodontal health of abutments were observed after 3 years.
RESULTS AND CONCLUSION:Comparison of the patient satisfaction showed that, the aesthetics, retention conditions, masticatory function and comfort in magnetic attachment group were significantly better than traditional clasp retention group (P<0.05). The aesthetics and comfort in bal-cap attachment group were also better than traditional clasp retention group (P<0.05). There were significant differences on the retention conditions and comfort between magnetic attachment group and bal-cap attachment group (P<0.05). Gingival index was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). The abutment tooth mobility degree was the lowest in magnetic attachment group, then in bal-cap attachment group, and the highest in traditional clasp retention group (P<0.05). The periodontal pocket depth in magnetic attachment group and bal-cap attachment group was lower than that in traditional clasp retention group (P<0.05). The alveolar bone height was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). Experimental findings indicate that, precision attachment over-denture retention superior to traditional clasp removable partial denture in mandibular denture repairing. Magnetic attachment can provide better retention power and better protect the health of periodontal tissue compared with bal-cap attachment.
