OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

?-cell tumor is the most common functional neoplasm in islets.The localization of the tumor remains difficult in clinical practice.The application of various diagnostic imaging techniques are reviewed.

Objective To investigate the stimulate angiogenesis effect of bone marrow stem cell mobilization on coronary collateral development in the hearts of experimental myocardial infarction rats.Methods Left anterior descending coronary arteries were ligated to produce acute myocardial infarction(AMI)model in Wistar rats.Bone marrow stem cells were mobilized and home to the site of myocardial infarction by ginsenoside Rgl and Simvastatin.Hearts were harvested in the 24th hour,1st and 4th week after AMI modeling for histopathological examination.Immu nohistochemisty were used to detect infiltration of CD+34 cells and the expression of VⅢ factor in the part of ischemia.And infarct area were measured.Results Infarct area in mobilized group was obviously less than in AMI group.There were a great number of monocytes infiltrating with CD34 expression by immunohistochemisty in myocardial infracted zone in mobilized rats.Capillary density in mobilized group was greater than those of AMI and sham-operated groups.Conclusion In the AMI model of rat,bone marrow stem cells can be mobilized by ginsenoside Rgl and Simvastatin.The capillary density can be increased by mobilizing bone marrow stem cells.Ginsenoside Rgl and Simvastatin can improve the acute ischemic cardiac function by enhancing angiogenesis.

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.

Objective To establish an evaluation system to assess the effect of personnel training program for health professionals in the hospital,in order to achieve the goal that improve the overall competitiveness of the hospital.Methods Comparing and analyzing the differences in research project,research achievements,personnel capacity building before and after implementation of the training program.Paired T-test was used to exam the differences.Results There are statistically significant differences for proposed analyses (p ≤ 0.05).Conclusions The outcome of this study indicates that the personnel training program is extremely important to further development of the hospital.

Objective To observe effects and mechanisms of insulin on reperfusion injury after cerebral ischemia.Methods Sixty-six male Wistar rats were used in this study.All rats were divided into 3 groups as treated group(A),control group(B) and random sham-operated group(C).Four-vessel occlusion was used to establish global cerebral ischemia reperfusion model in study groups.The treated group were divided into 5 groups(A1-A5) and intraperineally injected with biosynthetic human insulin 2 IU/(kg?d) and 50%glucose 2 g/(kg?d) for 7 days,the blood glucose was monitored in preoperative and postoperative 3,6,12,24 h,and the blood glucose was maintained between 3.5-6.5 mmol/L.These animals of control group were given with saline 2 mL/(kg?d) for 7 days in abdominal cavity.All the rats were killed in the seventh day,brain homogenate was collected for detection of neuron specific enolase(NSE)and nitric oxide(NO).The hippocampus was separated for observation of electronic microscope.Results Concentration of NSE in brain tissue in group C was significantly higher than that of group A and group B,while the level in group A was higher than that of group B.Concentration of NO in group C was lower than that of group A and group B while the level of NO in group A was significantly lower than that of group B.Electron microscope showed that the ultrastructure of sham-operated group was nearly normal,damage degree of hippocampal neuron and gliacyte and capillary was gradually worse from group A1,A2 to A4,the damage degree of group B1,B2 and B4 was serious and there was no difference among them.Conclusion Insulin can really promote recovery of the cerebral injury after ischemia reperfusion.

Objective To investigate clinical features and therapeutic protocols of vulvovaginal-gingival syndrome(VVGS). Methods Clinical data were collected from 11 female patients with VVGS and analyzed. Results Among the 11 patients, the mean and median ages at a definite diagnosis of VVGS were both 46 years, and the average disease duration was 4 years. Painful erosive erythema was found on the vaginal vestibule in 7 patients, on the gingiva in 10, as well as on the bilateral buccal mucosa in 5. Additionally, 8 and 4 patients reported dyspareunia and vaginal hemorrhage, respectively. Seven patients were treated with low-dose oral methylprednisolone combined with hydroxychloroquine or colchicine, and the other 4 were treated with oral hydroxychloroquine alone. Furthermore, all of the 11 patients applied topical tacrolimus 0.1%ointment. Finally, 8 patients were cured or markedly improved. No obvious adverse reactions were observed in any of the patients. Conclusions VVGS mostly occurs in middle-aged women, with the vaginal vestibule and gingiva as predilection sites of painful erythema and dyspareunia as common symptoms. Patients have good responses to methylprednisolone combined with hydroxychloroquine, and hydroxychloroquine alone also shows good efficacy in patients with mild VVGS. Tacrolimus 0.1%ointment can be one of drugs for topical maintenance treatment of VVGS.

Objective To investigate the feasibility of ultrasmall superparamagnetic iron oxide- enhanced(USPIO)-enhanced MR imaging for monitoring synovitis of antigen-induced arthritis in rabbit model and explore the optimal MR imaging sequences.Methods Nine female white rabbits with antigen(0.5 ml mBSA,2 mg/ml)induced arthritis of the right knees were used in the study.The left knees of these rabbits and both knees of another 3 rabbits served as the control.Nine to 28 days(mean 21.3 d)after successful model induction,all knees were imaged before and 24 h after intravenously injection of USPIO (0.3 ml/kg),among which 2 rabbits were also imaged at 48 and 72 h after administration of USPIO respectively.The MR protocol included spin-echo(SE) T_1WI,fast spin-echo(FSE)T_2WI,gradient echo (GRE)T_2~* WI and short tau inversion recovery(STIR).Images were analyzed quantitatively and qualitatively based on signal characteristics and patterns of the synovium.Paired t-test was used for the analysis of the signal intensity of inflammatory synovial membrane before and 24 h after injection of USPIO. MR findings were correlated with histopathology.Results Arthritis was successfully induced in all 9 right knees with intraarticular injection of mBSA.Pathological examination revealed hyperplasia of synovium with infiltration of USPIO-loaded-macrophages.MR depicted synovial thickening(thickness 2.07?0.97 mm) and joint effusion.Synovium and joint fluid appeared as slightly hypo- or iso-intense on T_1 WI and hyper- intense on T_2 WI or T_2~* WI.Twenty four hours after USPIO injection,significant T_1 enhancement(ASNR 41.91%?27.94%),negative T_2 and T_2~* enhancement(△SNR -34.92%?11.77% and -57.24%? 16.05%)were demonstrated in the region of synovial inflammation respectively.The signal at 48 h and 72 h changed less than that at hour 24.No signs of arthritis occurred in all left knees and in all knees of the artificial model group.Conclusion Iron oxide phagocytized into macrophages can be a root cause resulted in signal change on USPIO-enhanced MR images.The gradient echo sequence should be the optimal sequence to be used in USPIO-enhanced MR imaging in antigen-induced arthritis.

OBJECTIVETo investigate extracellular splitting pattern of mitochondria and the depressant effects of CsA on the process and explore the mechanism of post-traumatic SIRS and its therapeutic strategy.

METHODSTen male SD rats with 60 to 70 days age and 240 to 280 g weight were used for mitochondrial isolation. Freshly isolated mitochondria were randomly divided into two groups, which were cultured in blood plasma with or without CsA respectively for 8 h. COX and MDH were assayed by ELISA every 30 min. Meanwhile, Rat macrophage cell line NR8383 were treated as follows, control (group A): cultivation with normal medium; NR8383+CsA co-culture group (group B): culture medium was supplemented with CsA of 10 mmol/L; NR8383+intact mitochondria co-culture group (group C): culture medium was supplemented with intact mitochondria (mtDNA=5 g/ml); NR8383+intact mitochondria+CsA co-culture group (group D): culture medium was supplemented with intact mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L; NR8383+disrupted mitochondria co-culture group (group E): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml); NR8383+disrupted mitochondria+CsA co-culture group (group F): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L. TNF-α and IL-6 concentrations in supernatant were assessed at 1, 3, 5 h after culture.

RESULTSIn the mitochondria plasma cultures, MDH and COX levels were increased with the time and peaked at about 3 h and 3.5 h; CsA can delay the appearance of peak to 4.5 h. Among different treated groups,there was no significant difference in TNF-α and IL-6 between group A and group B; there was significant difference in TNF-α and IL-6 other groups. After 1 h culture, compared with group C, no significant difference of TNF-α and IL-6 was observed in group D, while TNF-α and IL-6 were significant higher in group E; after 3 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while TNF-α and IL-6 were significantly higher in group E; after 5 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while no significant difference of TNF-α and IL-6 were observed in group E. At each time point, there was no significant difference in TNF-α and IL-6 between group F and group E.

CONCLUSIONMitochondria can split in serum with time, which will further activate macrophages. CsA has depressant effect to mitochondrial splitting on the process and will therefore inhibit the activation of macrophages.
