Objective To study the relationship between pathological, immunohistochemical and ultrastructural changes of skeletal myodystrophy (SMD) and the development of the disease.Methods SMD tissue of 20 cases were routinely processed,the paraffin sections,the semi thin sections and the ultrasthin sections were observed by light microscopy and electron microscopy.Results 20 cases with SMD tissue were divided into three groups: Simple SMD for 8 cases, major changes were regional; Progressive SMD for 10 ca ses, the pathological changes were diffuse with large amount of degeneration of cell organs; SMD derived from nerve injury for 2 cases, pathological changes of the part controlled by the nerve were observed. While SMD was injured, myosin got deneration first.Conclusion The pathological and ultrastructure changes could be used to judge the progressive degree of myodystrophin. The amount of lost myosin could forecast the progression of the disease.

[Objective] To investigate the protective effects of different extraction of Agaricus blazei Murrill on HaCaT cells damaged by UVB. [Methods] The cell viability which was detected by MTT method was used to determine the impact of different dose of UVB and different extraction of Agaricus blazei Murrill on normal HaCaT cells and HaCaT cells damaged by UVB. [Results] ①The HaCaT cells viability declined after irradiation with UVB, and it was a dose-dependent manner. The cell viability was 53.23%when the dose of UVB was 20mj/cm2. ②The water extraction at the concentration of 0.2~4mg·mL-1, aqueous extraction at the concentration of 0.1~2mg·mL-1 and crude polysaccharide at the concentration of 0.2~1mg·mL-1 could promote the proliferation of HaCaT cells, while aqueous extraction and crude polysaccharide inhibited the proliferation of HaCaT cells at higher concentrations.③The water extraction at the concentration of 1~4mg·mL-1, aqueous extraction at the concentration of 1~2mg·mL-1 and crude polysaccharide at the concentration of 0.5~1mg·mL-1 could enhance the cells viability which was irradiated by 20mj/cm2 UVB (P<0.01). [Conclusion] The different extraction of Agaricus blazei Murrill all could relieve the photo-damage caused by UVB, and it has the potential of anti-photoaging.

Objective To observe the synapse formation in hippocampal dentate gyrus, and the memory ability after transplanting bone marrow stromal cells (BMSCs) into lateral ventricle of ischemic brain injury rats. Methods BMSCs from femur of a Sprague-Dawley rat were cultured for 3 generations in vitro. 60 newborn Sprague-Dawley rats were divided into sham group (n=20), model group (n=20) and BMSCs group (n=20). The latter 2 groups were ligated the left common carotid artery, and the BMSCs group were injected BMSCs into the lateral ventricle 7 days after ligation. They were tested with Morris's water maze 8 weeks later, and then, the brains were immunohistochemical staining to detect synaptophysin (SY). Results The time of probe trial of acquisition phase (T1) and reveral phase (T2) decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). The integral optical density (IOD) of SY positive cells decreased in the model group compared with the sham group (P<0.05), and increased in the BMSCs group compared with the model group (P<0.05). Conclusion BMSCs implantation through lateral ventricle can improve the learning and memory ability of rats, which may associated with the synapse formation in dentate gyrus.

Objective To compare the clinical efficacy of nedaplatin and cisplatin combined with docetaxel in the treatment of cervical cancer.Methods 80 patients with cervical cancer were selected as the research subjects.According to different chemotherapy regimens,they were divided into observation group(40 cases)and control group(40 cases).The observation group adopted nedaplatin combined with docetaxel chemotherapy regimen,while the control group used cisplatin plus docetaxel chemotherapy regimens.The clinical curative effect,adverse reaction of chemotherapy,hospitalization related indicators,etc were compared between the two groups.Results The total effective rate of the observation group was 85.0%,which of the control group was 77.5%,the difference was not statistically significant(x2=0.739,P=0.739).The incidence rate of gastrointestinal reaction(Ⅰ-Ⅳ)in the observation group was 25.0%,which was lower than 82.5% in the control group(x2=26.560,P=0.000).The incidence rate of renal toxicity(grade Ⅰ-Ⅱ)of the observation group was 2.5%,which was lower than 17.5% of the control group(x2=5.000,P=0.025).The length of hospital stay of the observation group was(2.93 ±0.39)days,which was shorter than(4.97 ±0.81)days of the control group(t=14.352,P=0.000).The incidence rate of bone marrow inhibition(grade Ⅰ-Ⅱ)of the observation group was 43.0%,which was significantly higher than 25.0% of the control group(x2=4.381,P=0.036).1 year overall survival(OS),no local recurrence rate(LRF)and no distant metastasis survival rate(DMF)between the two groups had no statistically significant differences(all P>0.05).Conclusion Efficacy of nedaplatin or cisplatin combined with docetaxel in adjuvant chemotherapy of cervical cancer has similar prognosis,nedaplatin has less toxicity,and can shorten the time of hospitalization,patients are more likely to accept,it is worthy of clinical promotion.

Objective To explore the imaging characteristics of malignant lymphoma of intestinal tract.Methods Thirty-two cases of malignant intestinal lymphoma proved operatively and pathologically were studied .All cases were subjected to Ba-meal or double contrast Ba-enema examinations. There were 10 cases studied by CT scan and 19 cases by B-ultrasonography.Results By Barium studies we found 20 cases of lesions involving the small intestine or ileocecal junction and 12 involving the large intestine. In the former subgroup , we found regional dilatation of small intestine in 6, multiple intraluminal polypoid filling defects in 7, intestinal wall infiltration in 4, intraluminal nodular proliferation with ulcer formation in 3; while in the latter subgroup ,there were polypoid masses seen in 6, narrowing of intestinal lumen in 5 and coarse intestinal mucosa in 1.On CT scan , we found irregular thickening of intestinal wall in 5 cases , eccentric intraluminal mass in 2 and intestinal dilatation associated with thickening of intestinal wall in 3. B-ultrasonography showed beltoid low echo thickened intestinal wall in 5 cases ,pseudo kidney sign in 6 and lumpy low echoes in 2. Conclusion Barium study , CT scan and B-ultrasonography have different specific diagnostic characteristics for malignant intestinal lymphoma.In combination with these examinations are mutually beneficial in the diagnostic process.
