Objcetives To sparch for the change of cerebrospinal fluid ferritin (CSF-Ft) content and its clinical significance.Methods The 42 patients with acute lymphatic leukemia(ALL)diagnosed by bone marrow biopsy were divided into 3 groups. There were 14 cases in Ⅰ group [introduced therapy stage without central nervous system leukemia(CNSL)7, 24 cases in Ⅱgroup (complete remission stage without CNSL) and 18 cases in Ⅲ grotip (with CNSL). There were 17 patients with viral encephalitis in viral encephalitis group and 15 patients without central nervous system oisease in control group. The CSF-Ft and SFt were determined by radioimmunoassay.Results The CSF-Ft contents of Ⅰ、Ⅱ、Ⅲ 、viral encepbalitis and control groups are 7.03 ?2.21 ?g/L,6.75 ?1.94?g/L, 31.06 ? 8.85?g/L, 7.26?1.83?g/L and 6.52 ?1.57?g/L. The CSF-Ft content in Ⅲ group are bigher than that in the other group (P

OBJECTIVETo assess the clinical efficacy, safety and compliance of tianwang buxin decoction (TWBXD) combined with dormancy hygiene education (DHE) and TWBXD alone in treatment of sub-healthy insomnia patients of yin deficiency fire excess syndrome.

METHODSThe multi-centered, single blinded randomized clinical trial design was adopted. One hundred and one sub-healthy insomnia subjects of yin deficiency fire excess syndrome were randomly assigned to two groups. The 50 in the treatment group were treated by combined treatment with TWBXD and DHE, while the 51 in the control group were treated with TWBXD alone. The therapeutic efficacy, Pittsburgh sleep quality index (PSQI) score, clinical global impression-improvement (CGI) score, quality of life made by WHO (WHOQOL-BREF) score, and safety in the two groups were compared.

RESULTSThe effective rate in the treatment group was 68.08%, lower than that in the control group (75.00%), but the difference between them was statistically insignificant. The PSQI score in the treatment group were reduced from 12.00 +/- 2.25 to 7.55 +/- 2.91 (P < 0.01). It was reduced from 11.68 +/- 2.21 to 7.16 +/- 3.13 in the control group (P < 0.01). The improvement of CGI score and WHOQOL-BREF score was also shown in the two groups after treatment (P < 0.01). No significant difference was shown in each index between the two groups. There was no significant difference in CGI between two weeks after drug withdrawal and by the end of the therapeutic course in the same group (P > 0.05). There was no statistical significance in inter-group comparison (P > 0.05).

CONCLUSIONSignificant effect was achieved by TWBXD combined with DHE and by TWBXD alone. Their efficacies were equivalent, with high compliance and safety.

ObjectiveTo explore the curative effect in the patients with internal endometriosis by interventional therapy.MethodsUsing Seldinger technique,34 cases with internal endometriosis wereperformed bilateral uterine artery embolization.Observed postoperative menstrual quantity,dysmenrrhea degree,anemia and the change of the volume of uterine lesions.ResultsAll the patients were followed up for 1-3 years,menstrual quantity average decreasd of 59.1％P ＜ 0.05 ),the symptoms of dysmenorrhea was significantly eased in 28 cases (82.4％,28/34).All the patients of anemia haemoglobin were back to normal,volume of uterus average reduced 43.8％P ＜ 0.05 ),lesion was obviously smaller or disappear.Ultrasonography showed myometrium and blood flow signal of lesion was was obviously reduced.Conclusion Internalendometriosis by interventional therapy can get good results,symptoms improve significantly.

Background: Intralesional excision with curettage is the standard method of giant cell tumor (GCT) treatment, but the ideal filling material after curettage remains controversial. The purpose of this study was to compare the oncological and functional outcomes which underwent cementation or bone grafting after GCT curettage around the knee. Methods: We reported 136 cases with GCTs in distal femur or proximal tibia who accepted curettage from five clinical centers during the last 15 years. All patients were divided into two groups according to filling materials. Recurrence?free survival proportions were used to evaluate oncological outcomes while the Musculoskeletal Tumor Society (MSTS) 93 functional score was used to evaluate functional outcomes. Other parameters including surgical complication, general condition, and radiological classification had been analyzed. The valid statisitical data was analyzed using SPSS 13.0 software. Results: After GCT curettage, 86 patients (63.2%) accepted bone grafting while 50 patients (36.8%) accepted cementation. There was no statistical difference in age, gender, tumor location, radiological classification, fixation, follow?up time, and MSTS 93 functional score between cementation group and bone grafting group. The recurrence?free survival proportions showed that the recurrence rate in bone grafting group was higher than it in cementation group (P = 0.034). Surgical complication was lower in cementation group than that in bone grafting group but without statistically significant difference (P = 0.141). Conclusions: Parameters including patients'age, gender, tumor location, and radiological classification did not affect surgeons'treatments in cavity filling after GCT curettage. Cementation should be recommended because of easy usage, the similar postoperative knee function with bone grafting, and the better local tumor control than bone grafting.

The output and agronomic characters of 3-year-old Panax notoginseng cultured under stereo structure (upper, middle and down layers) were investigated, and the annual change of N, P and K of its planting soil were also studied. Results showed that, compared with field cultured Panax notoginseng, growth vigour and output of stereo-cultivation were significantly lower. But the total production of the 3 layers was 1.6 times of field. The growth vigor and production of P. notoginseng was in the order of upper layer > middle layer > down layer. The content of ginsenoside in rhizome, root tuber and hair root of P. notoginseng was in the order of upper layer > field > middle layer > down layer. Organic matter content and pH of stereo-cultivation soil decreased with the prolonging of planting time, which with the same trend of yield. Organic matter content of stereo-cultivation soil was significantly higher than field, but the pH was significantly lower. Contents of total and available N, P and K in stereo-cultivation soil and field decreased with the prolonging of planting time. The content of N and P were in the order of upper layer > middle layer > yield > down layer, the content of K was in the order of upper layer > middle layer > down layer > yield. Compared with field, the proportion of N and P in the organ of underground (rhizome, root tuber and hair root) of upper layer were increased, while decreased in middle and down layers. Proportion of K in underground decreased significantly of the 3 layers. In conclusion, the agronomic characters and production of stereo-cultivation were significantly lower than that of yield. But the total production of the 3 layers were significantly higher than field of unit area. And the aim of improving land utilization efficiency was achieved. Nutritions in the soil of stereo-cultivation were enough to support the development of P. notoginseng, which was not the cause of weak growth and low production. The absorbing ability of P. notoginseng to N, P and K nutrients was decreased by stereo-cultivation mode. So, improve the growth vigour of P. notoginseng from the perspective of adjusting the stereo-cultivation mode so as to improve the nutrient absorption capacity is the future direction.

The study was aimed to evaluate if the modified in situ cryopreservation could affect the biological function of mesenchymal stem cells (MSC) in vitro. Mesenchymal stem cells from human bone marrow were isolated by standard method and characterized with their morphology, cell-surface antigen profile and differentiation repertoire in vitro. The culture-expanded MSC were cryopreserved in situ with culture medium (DMEM-LG) containing 10% D MSO and 30% selected FCS in -70 degrees C. Following recovery of cryopreservation, differentiation to adipocytes, chondrocytes, and osteoblast in vitro and cell cycle analysis were performed to investigate whether the cryopreservation would change the differentiation potential of MSC. The results showed that after recovery of cryopreservation, there was no changes detected as compared with the culture-expanded MSC in both differentiation potency and growth pattern at 12 weeks. In conclusions: this optimized short term in situ cryopreservation at -70 degrees C could retain biological characteristics of human MSC for at least 3 months, and this method may be useful for cryopreservation of hum an bone marrow MSCs.
