Objective To investigate whether intervention with two different dosage of atorvastatin may benefit to plasma level of fibrinogen (Fg) in patients with acute cerebral infarction. Methods One hundred and two patients with acute cerebral infarction were randomly assigned into three groups:the control group (33 cases) treated without lipid-lowering drugs, 10 rag (30 cases) and 20 mg (39 cases) atorvastatin group with 3 days of treatment. Before and after the treatment, the plasma levels of Fg and lipids were detected.Results The treatment of 10 mg atorvastatin did not significantly decrease the level of Fg. Compared to the control group, the level of Fg was markedly reduced by 20 mg atorvastatin (21.6% vs 3.2%,P< 0.05). No changes of lipid levels were observed in any group before and after the treatment, whilst there was no relation between the decreasing percentage of Fg and that of TC(r = 0.125 ,P= 0.618), TG(r = 0.147,P = 0.573) or LDL- C (r = -0.279, P = 0.235 ), HDL-C (r = -0.021, P = 0.157). Conclusion Treatment with high dose atorvastatin (20 mg) for 3 days could reduce the level of Fg, and improve the function of vascular endothehum,which may promote the stabilization of atherosclerotic plaque.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus medications on senile osteoporosis (SOP), and to explore the related mechanisms. Methods: A total of 70 elderly participants with osteoporosis were randomly divided into an observation group and control group, with 35 cases in each group. The control group was treated with conventional drugs, and the observation group was treated with heat-sensitive moxibustion on the basis of the conventional drugs. Both groups were treated for 3 months. Before and after treatment, assessed the visual analog scale (VAS) and Oswestry disability index (ODI) scores, determined the bone mineral density of the participants' lumbar spine (L2-L4) and left femoral neck, and detected the participants' serum bone morphogenetic protein-2 (BMP-2) and osteoprotegerin (OPG) levels. Results: After treatment, the VAS scores of both groups were lower than before treatment (both P<0.05), and the VAS score of the observation group was significantly lower than that of the control group (P<0.05). After treatment, the bone mineral density values of the lumbar spine and left femoral neck in both groups were significantly higher than before treatment (both P<0.05), and the bone mineral density values of the observation group were higher than those of the control group (P<0.05). After treatment, the ODI scores of the two groups were lower than those before treatment (both P<0.05), and the ODI score of the observation group was lower than that of the control group (P<0.05). After treatment, the serum BMP-2 and OPG levels in the observation group were significantly higher than those in the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus medications for SOP can significantly relieve patients' pain, improve dysfunction, and increase bone density, which may be related to the improvement of the serum BMP-2 and OPG levels.

AIM:To observe the effects on human keratocytes by cationic liposome LipofectamineTM 2000(LF2000).to investigate the efficiency and safe range applied in human keratocytes,and establish basis for gene therapy of human keratocytes.METHODS: Human keratocytes cultured in vivo within 3 to 5 passages were used in experiment after being identified.The effects on proliferation of cultured human keratocytes by LF2000 with different concentrations and time were evaluated By MTT:the effects of LF2000 on the survival rate and its relation with 5,10,20,40.80mg/L concentration and time were detected by trypan blue staining.related with concentration and time.The cellular proliferation and survival rate declined when concentration of LF2000 was above certain level,and this effect increased as time became longer.LF2000 had no effect with concentration under 40mg/L for 24 hours. CONCLUSION:LF2000 did ont cause cytotoxicity during a concentration range"tested",and it is hoped to play an important role in gene therapy of human keratocytes.

Objective To investigate the effect of testosterone on mitotic orientation in rat prostate epithelial cells and the relative differential gene expression.Methods Twenty SPF male SD rats were divided into 2 groups at random and then subjected to castration.One group of rats was administrated with testosterone 3.7 mg daily for 30 days and the control group was only injected with olive oil.Microscopic analysis was performed using immunohistochemistry.Differential gene expression analysis was conducted by gene microarray and RT-PCR techniques.Results In the testosterone-adminis-trated group, there was a significant mitosis orientation parallel to the basement membrane.But in the control group, mito-sis orientation was oriented perpendicular to the basement membrane.Using the gene microarray and RT-PCR techniques, the cell proliferation genes such as Ran, Tgm4 and Wnt2 in Wnt signal pathway were up-regulated in the testosterone group.Conversely, suppressor cell proliferation genes such as Dkk3 and Fas were down-regulated.Conclusions Mitotic orientation of prostate epithelia cells is changed after testosterone administration.Wnt signal pathway and AR singling path-way also have an influence on the mitosis orientation and cell proliferation.

Objective To investigate the changes of the constitution and its ratio of collagen fiber in the process of masseter reattachment following different osteotomies of the prominent mandibular angle so as to offer guidance for the resection of mandibular angle. Methods Sixteen adult goats were randomized into four groups. In group A we performed unilateral curved osteotomy of the mandibular angle. In group B unilateral curved ostectomy was performed with partial masseter resection. In group C unilateral angle splitting ostectomy, while in group D unilateral dissection of the masseter muscle was conducted. The constitution and its ratio of collagen fiber in the interface were observed at 1-month, 2-month, 3-month, and 6-month after operation. Results On the changes of collagen fiber in the process of muscular reattachment, at 1-month post-operation, the constitution of collagen fiber (types Ⅰ and Ⅲ) in groups A and B were significantly different from that of control group (P<0.05). However, both groups C and D had no statistic difference from control group (P>0.05). At 2-month, 3-month and 6-month post-operation, those of all experimental groups had no statistic difference from control group. And with time, the percentage of collagen fiber type Ⅰ increased and type Ⅲ decreased gradually. Conclusion The recovery sequences of masseter muscle reattachment in this study are firstly group C, secondly group A and finally group B. It suggests that the recoveries of mastication and other oral activities are different. Group B turns out to be with a slow muscle reattachment. Thus, we recommend treating different kinds of mandibular hypertrophy with different ostectomies.

BACKGROUND:Being used in senile intertrochanteric fracture, the third generation of Gamma nail may isolate fracture fragments and it is difficult to be secured in the rotor, so the stability is poor. Varus deformity easily appears, which is difficult to support or satisfactorily reset. OBJECTIVE:To compare the effects and stability of the proximal femoral locking plate and the third generation of the gamma nail in the treatment of stable intertrochanteric fracture. METHODS:(1) A total of 64 patients with intertrochanteric fractures were respectively treated with the third generation of the gamma nail fixation (n=32) and proximal femoral locking plate fixation (n=32). Fracture reduction and healing were assessed using anteroposterior and lateral radiographs. Femoral rotor varus angle and intertrochanteric medial inclination received biomechanical measurement. (2) Eight femoral specimens whose shape and size were approximated were selected to be randomly assigned to Gamma 3 group and proximal femoral locking plate group (n=4), which respectively received Gamma 3 fixation and proximal femoral locking plate fixation. After axial compression test and destruction test, load-displacement curve was drawn. The maximum yield load value was calculated by torsion test. RESULTS AND CONCLUSION:Operative time and intraoperative blood loss were significantly more in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). The fracture quality assessment results were better in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). The axial stiffness and corresponding torque of various torsion angles were smaler in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). Experimental results indicated that in the course of fixating intertrochanteric fracture merged with greater trochanter fracture, the proximal femur locking plate has obtained more biomechanical stability.

OBJECTIVE:To explore the efficacy and safety of probucol combined with butylphthalide in the treatment of pa-tients with acute cerebral infarction. METHODS:172 patients with acute cerebral infarction were randomly divided into observation group and control group,86 cases in each group. All patients received conventional treatment for acute cerebral infarction,includ-ing thrombolysis,anti-platelet aggregation,reducing intracranial pressure,nutritional support,intensive lipid-lowering within onset 4.5 h,timely treatment of the underlying diseases;based on it,control group received Probucol tablet,0.5 g every times,bid. Ob-servation group additionally received Butylphthalide and sodium chloride injection,100 ml every times,bid,in 9:00 and 17:00 ev-ery day,infusion within 50-90 min. Both groups lasted for 2 weeks. Lipid metabolic indexes,the changes of serum S100β,NSE and hs-CRP levels,NIHSS score,clinical efficacy before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:Compared with before treatment,triglyceride(TG),total cholesterol(TC)and low-density lipoprotein cholesterol (LDL-C) levels in 2 groups significantly decreased,high-density lipoprotein cholesterol level significantly increased, and TG,TC and LDL-C levels in observation group decreased more significantly,the differences were statistically significant(P<0.05). Serum S100β,NSE and hs-CRP levels and NIHSS scores in 2 groups significantly decreased,and NSE level NIHSS scores and in observation group decreased more significantly,the differences were statistically significant (P<0.05). The total effective rate in observation group was 89.5%,significantly higher than control group (62.8%),the difference was statistically significant (P<0.05). There were no obvious adverse reactions during treatment,and also no obvious liver and kidney function,blood coagula-tion and ECG changes. CONCLUSIONS:Probucol combined with butylphthalide can effectively improve the lipid metabolism and decrease serum NSE level in the treatment of patients with acute cerebral infarction,and plays positive role in early recovery of neu-rological function.
