Objective To investigate the relationship between MLCP and hypertension pathomechanism of SHR by comparing 130 kD、38 kD、21 kD subunits in aorta,heart,kidney and brain of spontaneously hypertensive rat(SHR) and Wistar Kyoto rat(WKY).Methods The aorta,heart,kidney and brain were obtained from 10 SHRs and 10 WKY rats,and each tissue was freshly removed and weighed and rapidly frozen in liquid nitrogen,homogenized with buffer solution,total protein concentration was rectified according to the methods of Bradford,and SDS-PAGE、Western blots and chemo-luminescence were carried out to determine the content of three subunits,the results were estimated by ABS.t-Test and ANOVA were used to analyzed data.Results The contents of 130kDa,38kDa,21kDa subunits of SHR among the different organs were markedly different,the highest contents of 130kDa was located in the aorta;but the kidney had the highest contents of 38kDa subunit and 21kDa subunit was the highest in the aorta too.Conclusion The difference among the contents of 130kDa subunit、38kDa subunit and 21kDa subunit of SHR and WKY in the different organs implied that abnormity of MLCP' structure and function was associated with hypertension pathomechanism of SHR.

Objective:To explore the imaging features of complicated lymphocele after the pelvic lymph node dissection. Methods: After pelvic lymph nodes dissection, lymphoceles in pelvic cavity of 47 patients with gynecological malignant tumor were found by magnetic resonance imaging (MRI) and all of these imaging data were retrospectively analyzed.Results:All of 47 cases had lymphoceles in pelvic cavity, and the number of lymph node lesion was 52 (30 were at left side of pelvis, 22 were at right side of pelvis); the distribution of most lymphocele were around of external vein and artery of iliac; the main MRI features were roundness, oval, reniform or dumb-bell shape with smooth and uniform lymphocele wall, and the intracystic manifestations were long T1signal and long T2signal; the manifestation of DWI was high signal of limited dispersion; after enhancement scan, the wall of lymphocele and intracyst appeared middle reinforcement signal, and there was no obvious reinforcement signal in cystic contents.Conclusion: There are characteristic MRI imaging manifestations in lymphocele, and the diagnosis of MRI is reliable and accurate.

Objective To explore the effect of aerobic exercise on cardiac function,heart rate recovery and the quality of life of elderly heart disease patients.Methods One hundred senile heart disease patients were studied.They were randomly divided into a control group and an observation group,with 50 in each group.Both groups were provided with the conventional anti-platelet aggregation treatment,dilation of blood vessels and control of blood pressure.The observation group was also given individualized aerobic exercise training.At the outset and after 3 months the cardiac function and heart rate recovery of both groups were observed,and their quality of life was evaluated using the SF-36 life quality scale.Results After the treatment,the average left ventricular ejection fraction of those in the observation group was significantly better than before the treatment,and significantly better than the average among the controls.The average 6-minute walking test time and average maximum oxygen uptake in the observation group were also significantly better than before the treatment and significantly better than among the controls.The average peak heart rate and HRR1 in the observation group had increased significantly,and significantly more than those of the control group.The average total SF-36 score in the observation group was also significantly higher.Conclusion Individualized aerobic exercise can significantly improve cardiac function and promote heart rate recovery in elderly patients with heart disease,which is of clinical value for improving their quality of life.

Objective To explore the clinical diagnositic code(CDC)in ovarian endometrial cysts (OEC).Methods 218 cases of pelvic masses were investigated by use of symptoms,signs,B mode sonography and CA125.172 cases were diagnosed with OEC out of 218 cases,While 46 cases were ruled out by combination exploratory laparotomy and laparoscopy.Meanwhile we compared it with revisional american fertility society(r-AVS)including diagnosis and staging.Results The operation results of 218 cases were compared with the results of CDC and its Diagnositic Sensitiveness;Specificness;Positive predictive value;Negative predictive value;Diagnositic accordance rate as well as Diagnositic index of CDC were 96.4%,79.6%.93.0%,90.0%,91.7% and 73.4% respectively(χ2=127.818,P＜0.001).Further more,172 cases of OEC which diagnosed with CDC were further subdivided into three stages as 1,2,3 according to its score,mild;moderate;heavy and this stage category were compared with the category of AFS(Ⅰ-Ⅱ,Ⅲ,Ⅳ),the Diagnositic accordance rate of two categories were 95.6%,95.6% and 83.0% respectively,No significant difference were found in Var.mitis and medium-sized(χ2=0,P＞0.05).but the Medium-sized and Gravis tape was significance(χ2=4.472,P＜0.05).Conclusion CDC has a better coincidence with operation in the diagnosis of OEC which can be used in the non-traumatic diagnosis and staging of OEC in clinic.

Objective To investigate the clinical efficacy of electrothermal acupuncture in treating ankylosing spondylitis.Method Sixty patients were randomly allocated to treatment and controlgroups, 30 cases each.The treatment group received electrothermal acupuncture and the control group took methotrexate plus sulfasalazine.The extent of chestexpansion, the severity of sacroiliac joint tenderness, the number of tender joints and morning stiffness time were examined,Schober's testscores at different time points were recorded and interleukin-1 (IL-1) and interleukin-6 (IL-6) contents were measured before and after 4 and 8 weeks of treatment.Result In the treatment group, there were statistically significant differences in the extent of chestexpansion, the severity of sacroiliacjoint tenderness, the number of tender joints, morning stiffness time andSchober's testscores after 4 and 8 weeks of treatment compared with before treatment (P<0.05).There were statistically significant pre-/post-treatment differences in IL-1 and IL-6 contents in the two groups (P<0.05). The total efficacy rate was 80.0% in the treatment group and 73.3% in the control group; there was no statistically significant difference between the twogroups(P>0.05). ConclusionElectrothermal acupuncture has a marked therapeutic effect onankylosing spondylitisand is of high safety.The mechanism of electrothermal acupuncture treatment forankylosing spondylitismay be related to its regulating IL-1 and IL-6 levels in the body.

Objective To compare the differences of target-volume(PTV) coverage and organ at risk (OAR) protection between three dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy(IMRT) for patients with pelvis metastasis of cervical cancer underwent radical hysterectomy and pelvic lymphadenectomy. To explore the optimal treatment methods for pelvis metastasis of cervical cancer.Methods 10 patients with pelvis metastasis of cervical cancer underwent radical hysterectomy and pelvic lymphadenectomy were selected for this study. The images scanned by CT were transferred to treatment planning system to generate 3DCRT and IMRT plans. The impacts of 3DCRT on PTV were compared with those of IMRT. Isodose line and dose volume histograms(DVH) were used to evaluate to the dose-distribution in PTV and OAR. Results For 95 % confidence interval, the margin from CTV to PTV was 1 cm. Conformal indexs (CIs) of PTV for 3, 4, 5 and 6 fields 3DCRT were 0.46, 0.67, 0.68 and 0.68, respectively. When beyond 4 fields, the advantage of adding fields was not significant. CIs of PTV for 5, 7, 9, 11 and 13 fields IMRT were 0.75, 0.83 0.84, 0.85 and 0.85, respectively. When beyond 9 fields, the advantage of adding fields was not significant. The maximum dose of the bowl and spine cord in IMRT plans were lower than that in the 3DCRT plans (P <0.05). Maximum dose of OAR had no significant differences (includingt the bone, recttum and bladder) between IMRT and 3DCRT plans. Conclusion For patients with pelvis metastasis of cervical cancer after radical surgery, 4 fields planning in 3DCRT and 9 fields planning in IMRT are feasible. At high dose levels, the IMRT plans can more significantly protect the bowl and spine cord and decrease the radiation volume of colorectal and urinary bladder at risk than 3DCRT, so IMRT may potentially diminish probability of the normal tissue complications.

BACKGROUND:Drug treatment is the main method for the treatment of diabetes currently, but the development of the disease and occurrence of related complications are the chal enges to the effect of drugs. OBJECTIVE:To investigate the effect and feasibility of co-transplantation of bone marrow mesenchymal stem cells and islet cells for the treatment of diabetes. METHODS:The rat bone marrow mesenchymal stem cells were separated and purified, and cultured in vitro to establish the diabetes models. The rat diabetes models were injected with bone marrow mesenchymal stem cells, co-cultured mixture of bone marrow mesenchymal stem cells and islet cells, and normal saline or phosphate buffer (control). The effect of transplantation was evaluated through observing the blood glucose levels, insulin secretion, and pathological changes of pancreatic tissue in the rat diabetes models. RESUTLS AND CONCLUSION:In the diabetes rats treated with bone marrow mesenchymal stem cel transplantation, the C-peptide levels were significantly increased after transplantation, while the blood glucose levels were significantly decreased, but not lower than the normal level, and the blood glucose levels were increased again with the time prolonging. In the diabetes rats treated with co-transplantation of bone marrow mesenchymal stem cells and islet cells, the blood glucose levels were decreased significantly and lower than the normal level which was maintained in a certain time, and the decreasing degree was larger than that in the rats treated with simple bone marrow mesenchymal stem cel transplantation. Co-transplantation of bone marrow mesenchymal stem cells and islet cells is feasible for the treatment of diabetes with a certain effect.

Objective To explore the application value of diffusion-weighted imaging(DWI) in distinction of skull base chordoma from chondrosarcoma.Methods The clinical data and imaging findings of basicranial tumor confirmed by pathology,including 14 patients with classic chordoma,9 with poorly differentiated chordoma and 18 with chondrosarcoma were analyzed retrospectively.The lesion location,enhancement patterns,signal intensity on T2 WI relative to gray matter,and apparent diffusion coefficient (ADC) values were reviewed.The enhancement pattern was scored as 0 (little or non-enhancement),1 (heterogeneous enhancement),or 2 (homogeneous enhancement in ≥90％area).The data were analysed by Kruskal-Wallis test.Results There were significant differences in the mean,minimum and maximum ADC values,the intensity on T2 WI and the enhancement pattern among the three tumor types (P ＜0.05).However,the differences in the score of enhancement pattern and lesion location were not found (P＞0.05).Conclusion DWI may be helpful for the diagnosis of skull base chordoma from chondrosarcoma,and the accuracy rate will be improved when combined with T2WI intensity.

As an important material in pharmaceutical and chemical industry, β-alanine was mainly produced by chemical methods. L-aspartate-α-decarboxylase could catalyze the α-decarboxylation from L-aspartate to β-alanine. Determinations for specific activities of PanDs from Escherichia coli, Corynebacterium glutamicum and Bacillus subtilis were performed in this study (0.98 U/mg, 7.52 U/mg and 8.4 U/mg respectively). The optimal temperature and pH of PanDs from C. glutamicum and B. subtilis were 65 degrees C, pH 6.5 and 60 degrees C, pH 6.5 respectively. According to our research, PanD from B. subtilis could be more appropriate for industrial application because of the higher activity and thermostability when compared to PanDs from E. coli and C. glutamicum which had been the most studied. We also analyzed and discussed the special post-translation self-cleavage phenomenon and the mechanism based inactivation.
