[Objective]To study the clinical experience of Professor LIU Zhe treatment of essential tremor with acupuncture.[Methods]The paper states Professor LIU's understanding of treating essential tremor from the pathogenesis, acupuncture points and acupuncture manipulations, then summarizes the principle, regularity, and the features of acupuncture manipulations for Professor LIU treating essential tremor of different types of syndrome, so as to elaborate the clinical experience of Professor LIU. [Result] Professor LIU Zhe considers the age-dependent deficiency of qi and blood and insufficient liver and kidney syndrome to be a common one of essential tremor, as an experienced doctor, he distinguishes different types of syndrome from sign, tongue, pulse and so on. He places great emphasis on nourishing the bone marrow and tonifying liver and kidney. According to the symptoms select acupuncture points with the effects of nourishing the bone marrow and calming the liver to stop the wind, tonifying liver and kidney and supplementing qi and nourishing blood. Professor Liu sets a high value on selecting points of head and makes use of the point of Fengchi with unique acupuncture manipulations to relax cerebrovascular. In clinically, the curative effects are remarkable. [Conclusion]The unique method for treating essential tremor of Professor LIU gives some inspirations for clinic. It is worth of a deep study and spreading.

Objective To explore the clinical characteristics and effects of thrombolytic and anti coagulation treatment in over 70 year old patients with pulmonary thromb embolism(PTE). Methods The clinical findings, diagnostic techniques, effects of thrombolytic therapy and anti coagulation in 58 over 70 year old patients with PTE were analyzed retrospectively. Results Deep venous thrombosis (DVT) in lower limbs (74 1%) was the most common thrombolism prone factors in our study. Limitation of movement and long term stay in bed due to a variety of causes were in the next place. The clinical findings were atypical, associated with a false diagnostic ratio of 46 5% in elderly patients with PTE. Undefined causal and different degree of dyspnea along with sudden and persistent hypoxemia were the main characteristics. Spiral CT and radioactive nuclear ventilation perfusion scan were important methods for diagnosis of PTE with positive finding of 95 7% and 62 5%, respectively. The effective and cure rate of thrombolytic therapy combined with anti coagulation, anti coagulation and anti platelet therapy was 91 3%, 75 8%, 0 and 47 8%, 17 2%, 0, respectively. Conclusions The most common risk factors of PTE in the elderly was DVT and the long term stay in bed or stay without active moving. The clinical symptoms were not only atypical but also variable. Thrombolytic with anti coagulation therapy is safe and effective, but anti platelet coagulation alone is not benefit.

Objective To study the influence of oral antigens on the expression of costimulatory molecules CD80/CD86 on the surface of M and to investigate the genesis of pregnancy immunological tolerance induced by oral antigens through CD80/CD86. Methods Mice of spontaneous abortion(CBA/J?DBA/2) were divided into two groups: immune group and non-immune group.Trophoblast membrane antigen-2(TMA2)or ovum albumin(OVA) was administered orally to the mice in the immune group.Mice of normal pregnancy(CBA/J?BALB/c) were served as controls.The number of CD80/CD86 M of spleen and mesenteric lymph node(MLN) were determined by double-label FCM method. Results In the MLN,CD80 M of non-immune group was increased significantly as compared with that of the control group(P

Objectives To study the changes of hard tissue before and after orthodontic treatment for Angle's class Ⅲ malocclusion adolescence patient with maxillary front traction. Methods 20 cases of Angle's class Ⅲ malocclusion adolescence patients were treated by front traction in maxilla, while there were 20 cases of Angle's class Ⅰ malocclusion adolescence patients as the control group. Cephalometric a-nalysis was carried out before and after the treatment. Data were analyzed by SPSS11.0 system using paired t-test. Results There were significant increases in the length, anteroposterior diameter and thick-ness of maxillary sinus (P<0.05), while there was no significant differences in the site and central point of maxillary sinus(P>0.05). Conclusions It is a effective approach to change the hard tissue after ortho-dontic treatment for Angle's class Ⅲ malocclusion adolescence patient with front traction in maxillary area.

[Objectives]This study was designed to evaluate the treatment effects of a new movable molardistalization appliance for distal movement of maxillary first molars on Angle's Class Ⅲ malocclusion adolescence patients with the second premolar crowded.[Methods]Sixteen patients were treated by a new movable molardistalization appliance.Cephalometric analysis and model measurement was carried out before and after the treatment.Data were analyzed by paired t-test.[Results]The molars were distalized 5 mm during an average time of 3.8 months.There were significant increases in the Angle SNA and A-NPg(P ＜0.05).[Conclusion]it was a effective way to get space and improve patient's profiles on Angle's Class Ⅲ malocclusion adolescence patients with the second premolar crowded by the new movable molardistalization appliance.It was also conducive to patient's oral hygiene.

Objective To investigate the effect of Gum mastic combined with gemcitabine on human pancreatic carcinoma BxPc-3 cells and its mechanism.Methods Cell proliferation and apoptosis were examined using the methyl thiazolyl tetrazolium assay and propidium iodine staining,respectively.After BxPc-3 cells were treated with different concentrations of Gum mastic and gemcitabine,the expression of NF-κB p65 subunit,IkB,Bcl-2 and Bax proteins was detected by Western blot.BxPc-3 cells were injected subcytaneously into nude mice to establish pancreatic xenograft tumors,and the changes of tumor volume were monitored.Results Compared to either single agent,treatment with Gum mastic (40 mg/L) combined with gemcitabine (10 mg/L) for 72 h signi cantly inhibited the proliferation of BxPc 3 cells (P＜0.01).Its rate of apoptosis(45.13±4.01)was more than Gum mastic,gemcitabine(P＜0.01) and control group (5.07 ± 1.37,P＜ 0.01).When cells were treated with gemcitabine in combination with gum mastic in human pancreatic carcinoma BxPc-3 cells for 48 h,the IκB level was increased,whereas NF-κB activation was blocked; the expression of Bax protein was substantially increased,but Bcl-2 protein was down-regulated; gum mastic or combined with gemcitabine could significantly inhibit the growth of pancreatic xenograft tumors (P ＜ 0.05).Conclusions Gum mastic could effectively strengthen the sensitivity of human pancreatic carcinoma BxPc-3 cells to gemcitabine.It may inhibit the expression of NF-κB p65 subunit and Bcl-2 proteins and increase the expression of IκB and Bax proteins.

BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.
