0.05].In 48 patients without lymph node metastasis,there was no significant difference between the OPN-positive and OPN-negative patients in survival times.Multivariate analysis revealed that survival times was associated with patients′sex(P=0.032)and TNM stage(P

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.

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.

Objective To observe the effects of all-tram retinoic acid(ATRA)on intercellular communication function and connexin 43 expression in acute leukemia bone marrow stromal cells(ALBMSCs).Methods ALBMSCs were cultured in vitro,and the ATRA(1?10~(-5)mol/L)was added after serial subcultivation.The expression level of Cx43 was detected by immunochemistry and flow cytometry, and the gap junction intercellular communication(GJIC)was examined by using cell scarification with dye transfer(CSDT)technique.Re- sults Before and after addition of ATRA,the positive rates of Cx43 expression as detected by immunochemistry in ALBMSCs were(47.2?2.04)% and(54.5?5.86)%,respectively.The positive rates of Cx43 expression in ALBMSCs as detected by flow cytometry before and after the addition of ATRA were(38.75?23.95)% and(49.5?5.46)%,respectively.The expression of Cx43 in ALBMSCs after adding ATRA was significantly higher than that before the addition of ATRA(P

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.

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.

Objective To study the causes of early death of patients with acute severe cervical spinal cord injury.Methods A retrospective analysis was done on 78 cases of acute severe cervical spinal cord injury,who were treated in our hospital between January 2003 and December 2007.The patients were divided into death group and survival group(survived more than 30 days after the injury).The clinical data including age,level of spinal cord injury,time of injury and admission,surgical treatment,duration between injury and surgery,neurogenic shock,central hyperthermia,hyponatremia,serum level of albumin,percentage of lymphocytes in serum,tracheotomy,and pulmonary infection,were recorded and analyzed. Results The proportion of high-level spinal cord injures(C1-C4) in death group(8/9) was significantly higher than that in the survival group(49/69,?2=18.086,P=0.000).Whereas the duration between injury and surgery in the death group was significantly shorter than that in the survival group(1-12 d,median 2 d vs 1-39 d,median 3 d;Z=-2.664,P=0.008).In the death group,4 of the 9 patients had neurogenic shock,and 4 developed hyponatremia,which were significantly more than those in the survival group(6/69,?2=12.392,P=0.000;19/69,?2=4.526,P=0.033).The percentage of peripheral lymphocyte on admission was(11.84?5.80)% in the death group,which was significantly lower than that of the survival group(19.17?16.64)%(t=-4.006,P=0.000).In the death group,7 patients received tracheotomy,and 8 patients showed pulmonary infection,the proportions were significantly higher than those in the survival group(10/69,?2=29.749,P=0.000;and 15/69,?2=17.266,P=0.000).Conclusions Several factors,including high-level injury(C1-C4),neurogenic shock,pulmonary shock,and tracheotomy,may cause the death of patients with acute severe cervical spinal cord injury in an early stage.

Objective To study the optimal timing of tracheotomy in patients with acute cervical spinal cord injury who need ventilation for a long time . Methods A retrospective research on seventy-nine patients with acute cervical spinal cord injury who underwent tracheostomy in our hospital from January 2011 to December 2015 was conducted .The 79 patients were divided into two groups.The patients with a duration from intubation to tracheostomy less than or equal to 10 days were enrolled in group A , and the duration more than 10 days, group B.The duration of ventilation , the length of ICU stay , and the incidence rate of lung infection were compared between the two groups . Results The duration of ventilation in the group A (192 ±58) h was less than that in the group B (348 ±53) h (t=-12.490, P=0.000).The length of ICU stay in the group A (9.8 ±2.7) d was less than that in the group B (15.9 ±2.2) d (t=-11.058, P=0.000).The incidence of pneumonia in the group A (16.2%, 6/37) was lower than that in the group B (38.1%, 16/42,χ2 =4.686, P=0.030).Mechanical ventilation was successfully withdrawn in 34 and 38 cases of group A and B, without significant difference (χ2 =0.000, P=1.000). Conclusion Early tracheostomy in patients with acute cervical spinal cord injury who need ventilation for a long time could shorten the duration of ventilation and the length of ICU stay , and decrease the incidence of pneumonia .
