Objective To investigate the expression and role of Caspase-3 during the development of non-traumatic avascular/aseptic necrosis of femoral head(ANFH).Methods Tissue samples were obtained from 22 femoral heads of 21 patients with ANFH.The samples were divided into three groups:early stage(6 cases),middle stage(8 cases) and late stage(8 cases) groups according to the progress of the disease.Meanwhile,19 tissue samples of 19 femoral heads were obtained from 19 cases of acute femoral neck fracture and set as a control group.The level of apoptosis of each group was compared in terms of the percentages of TUNEL positive osteocytes and empty osteocyte lacuna,and then the activity of Caspase-3 was detected by colorimetric method.Results Both the pecentages of empty osteocyte lacunae(F=45.43,P=0.000) and the TUNEL positive osteocytes(F=120.86,P=0.000) increased significantly with the progress of ANFH.The two indexes in the early and middle stage groups were significantly higher than those in the control(q=18.899,P0.05).Caspase-3 activity was not significantly related to the capacity of osteogenesis(r=0.126,P=0.425).Conclusions Caspase-3 is not the major executor of apoptosis in ANFH.It is very likely that it does not play a nonapoptotic role in the progress of the diseases.

Objective To study the analgesic effects of combination of fortanodyn and verapamil. Methods Used the model of the acetic acid induction writhing in mice and the method of hot-plate in mice, then observe the action of the mice after treatment with combination of fortanodyn and verapamil. Results Low dose Verapamil com-bined AP237 (40 mg/kg, 80 mg/kg)could enhance the threshold of pain of the mouse ache response obviously, and postponed the time which the mouse ache appeared (comparing using simply AP237 P <0.05 with controlled group P <0. 01) ;Low dose Verapamil combined AP237 (20 mg/kg,40 mg/kg) had the obvious inhibitory action in the body turning times of the mouse. Conclusion Verapamil can strengthen the analgesia function of AP237.

Ultrasonography (US) is extensively used in the diagnosis of prostate cancer; but with its disadvantages of poor sensitivity and specificity, frequently causes underdiagnosis, and over 50% of the results of transrectal ultrasound (TRUS)-guided biopsy fail to accord with those of surgical pathology. In addition to contrast-enhanced ultrasound and real-time elastography, various new ultrasonic techniques have been developed nowadays, such as prostate histoscanning, brachytherapy template-guided 3-dimensional mapping biopsy (3DMB), and MRI/US fusion. Prostate histoscanning is an ultrasound-based technology that uses computer-aided analysis to identify and characterize the foci of prostate cancer. 3DMB, involving the whole gland, has an even higher accuracy. MRI/US fusion integrates the advantages of pre-interventional MRI with those of peri-interventional ultrasonography, and offers high-resolution images and convenient puncturing. Constant development of ultrasonography will continue to add to its clinical application value.

AIM: To observe the clinical effect of the tonifying kidney pills with mingmuwuzi treating evaporative dry eyes.METHODS: This study adopted the positive drug control,prospective study,random number remainder grouping method to 65 cases of outpatient patients diagnosed with evaporative dry eyes which were divided into the treatment group 32 cases (64 eyes) and the control group 33 cases (66 eyes).The treatment group took the decoction of kidney pills with mingmuwuzi,combined with sodium hyaluronate eye drops.The control group simply use sodium hyaluronate eye drops,both group were set to 4wk for a course of treatment.To observe the symptoms and signs of two groups before and after the treatment,the change of the evaluation index and curative effect were evaluated.RESULTS: The effectiveness of the treatment group was 87.5%,the control group was 78.8%,the difference was statistically significant (z=-3.149,P<0.05).CONCLUSION: The treatment of the kidney pills with mingmuwuzi combined with sodium hyaluronate eye drops to evaporative dry eyes is more effective than the simple use of sodium hyaluronate eye drops.

Objective To measure the setup errors in thoracic esophageal carcinoma treated with intensity modulated radiotherapy (IMRT) using kilo-voltage cone-beam CT (kV-CBCT),and to evaluate the impact of the setup errors on the dose distributions in tumor target volume and the peripheral normal tissues.Methods Twenty-one patients with thoracic esophageal carcinoma undergoing image guided IMRT (IG-IMRT) were included in this study. Using kV-CBCT,173 setup errors of these patients were acquired before treatment.By shifting the isocenters,these setup errors were simulated in the 3-dimentional treatment planning system and the corresponding impact of the dose distribution in tumor target volume and peripheral organs were evaluated.Results The translational deviations of lateral,longitudinal and vertical directions were ( 2.73 ± 1.85 ),( 3.19 ± 2.71 ),and ( 2.35 ± 1.71 ) mm,respectively.The dose of gross tumor volume (GTV) was not impacted significantly by the setup errors. However,comparing with the standard plan without setup errors,the setup errors in the simulated plan reduced the dose of 95% planning target volume (PTV) by 3.38 Gy.The dose to PTV Dmin and PTV Dmean were also reduced by 9.83 Gy and 0.65 Gy respectively. The correction of setup errors improved the conformity index (CI) and the homogeneity index (HI) for PTV.The C1 and HI for the standard plan were 0.74 ± 0.10 and 1.07 ±0.02, respectively. The C1 and H1 for the simulated plan were 0.69 ± 0.08 and 1.13 ± 0.07,respectively.Statistically significance was observed in these differences ( t =3.43 and -3.91 respectively,P < 0.05 ). No statistical significance was observed in the dose differences in lungs,spinal cord and heart between the two plans ( P > 0.05).The mean maximum dose of the spinal cord was (42.20 ± 4.97 ) Gy in the simulation plan,which was (41.37 ± 2.75 ) Gy in the standard plan.For some patients,the maximum dose of the spinal cord exceeded the tolerance level of 45 Gy in the simulation plan,and one case even reached 52.8 Gy.Conclusions Using the image guidance of kV-CBCT,the setup errors can be reduced significantly for patients with esophageal carcinoma receiving IG-IMRT.The correction of setup errors can increase the treatment precision and enhance the dose in PTV.No significant dose changes were observed in the lung,spinal cord and heart as a result of setup error correctio.

Objective To evaluate the effect of endoluminal treatment for Budd Chiari syndrome (BCS) .Methods In 36 patients with BCS were treated by inferior vena cava(IVC) dilation and endoluminal stent placement guaded by ultrasonography, including self expanding mental Giaturco stent placement in 33 patients and pure dilation in 3 patients. Portosystemic shunts(PSSs) were followed in 13 patients with hepatic venous occlusion a week after the endoluminal treatment, including splenorenal(S R) shunts in 5 cases,and mesocaval (M C) shunts in 8 cases. Results After endoluminal procedures ,slight heart dysfunction appeared in 3 cases . After shunting ,acute pancreatitis occurred in 1 case, and upper gastrointestinal hemorrhage occurred and finally resulted in death in another case on the 10th day after PSS.All the 36 patients were followed up for 1 month to 8 years. Restenosis of the distal part of stent was found in 1 case 2 years after the operation,hepatic vein occlusion occurred in 1 case 1 year after the treament, hepatoma occurred in 1case 3 years after the treatment,and 1 patient died of C type hepatitis a year later; and 2 cases with infertility had babies 1 year later. All patients had no stent migration or occlusion of shunts .Conclusions Endoluminal therapy guarding by ultrsonography is a convenient, safe and effective method for Budd Chiari syndrome. For patients with hepatic venous occlusions, a portosystemic shunt is recommended.The above mentioned methods provide a feasible and effective means for some kinds of Budd Chiari syndrome.
