We built rats model of endometriosis applying autologus endometrial transplants to compare the graft vol-ume of the modeling rats before and after dosing,serum tumor necrosis factor alpha(TNF-α)levels in rats,and the expressions of vascular endothelial cell growth factor(VEGF)in ectopic endometrium.To compare with the control group,the graft volume of DingKunDan group was reduced and the serum TNF-αlevel declined ,and also the ex-pression of VEGF in ectopic endometrium was reduced.Their differences were statistically significant (P <0.05). DingKunDan can inhibit the growth of ectopic endometrium in endometrosis model rats.The mechanism may be re-lated to the decrease of the serum TNF-αlevel and the VEGF expression.

BACKGROUND: Different isolation and culture methods for bone marrow mesenchymal stem cell (BMSCs) will result in varying cell activity and purity, which will influence repair effect of tissue engineering. OBJECTIVE: To investigate the optimized methods of isolation and culture of BMSCs in vitro and validate the efficacy of cell acquisition. DESIGN, TIME AND SETTING: In vitro cytology trial was performed at the laboratory of Department of Orthopedics, Second Hospital of Shanxi Medical University from October to December 2007. MATERIALS: Two 3-month-old New Zealand rabbits were provided by Shanxi Institute of Livestock. METHODS: Lymphocyte isolation solution was added to DMEM culture solution containing fresh bone marrow. BMSCs were obtained and purified by gradient centrifuge and adhesion culture in vitro. Non-attached cells were moved to new culture flask every 8 hours. The solution was changed firstly after 5 days of culture. Trypsinization was conducted at cell confluence of 90%. The first, third and fifth passages of cells were harvested. MAIN OUTCOME MEASURES: The morphology of BMSCs was observed with phase contrast microscope; the growth curve was drawn to determine doubling time. The percentage of the wel1 growth P2 cells were identified by CD44 staining by flow cytometry. RESULTS: Primary cultured BMSCs were oval, spindle-shaped or polygonal, and adhered to plastic surface within 48 hours, exhibiting spindle-shaped or polygonal with clear nucleus, and reached 90% confluence within 14 days. The first, third and fifth passages of BMSCs showed S-type, and were in latent phase at 1-3 days, in log phase 3 days later, and cells came into platform phase at 7-8 days. The mean doubling time was 24.22 hours. CD44-positive cells were found in the second passage, with positive rate of 93.0%. CONCLUSION: BMSCs are easily isolated and cultured in vitro with good growth and high purity by gradient centrifuge and adhesion culture with lymphocyte isolation solution.

Objective To observe the expression of cyclooxygenase(COX)-2 in different malignancy astrocytoma by immunohistochemistry,so as to judge the invasive action of COX-2 in astrocytoma.Methods A total of 55 cases with astrocytoma underwent 63 times operation including 8 recurrent cases were selected,and 9 cases with severe brain injury who needed decompression surgery were selected as control group.The astrocytoma tissues and decompression surgery to remove tissues removed immediately fixed in 10％ formalin buffer solution.The expression of COX-2 was determined by immunohistochemistry.Results The positive expression rate of COX-2 in astrocytoma tissues was higher than that in decompression surgery to remove tissues[69.84％ (44/63) vs.1/9],and there was significant difference (x2 =11.589,P ＜ 0.01).The positive expression rate of COX-2 in recurrent astrocytoma tissues was higher than that in primmy astrocytoma tissues [8/8 vs.65.45％ (36/55)],and there was significant difference (x2 =3.957,P ＜ 0.05).With increased astrocytoma malignancy,the positive expression rate of COX-2 also increased,and there was significant difference (P ＜ 0.05).Conclusion COX-2 may have some relationship with the invasion of astrocytoma,leading to increase tumor grade,and relapse.

OBJECTIVE:To establish the quality standard of Chushi pill. METHODS:Microscopic identification and TLC were adopted for the qualitative identification of Cortex moutan,C. dictamni,Angelica sinensis,Rubia cordifolia and Gardeniae fructus in Chushi pill;HPLC was performed to determine the contents of paeonol and baicalin. It was performed on column of Kro-masil 100-5 C18 with mobile phase of methanol-water-phosphoric acid(47∶53∶0.2,V/V/V)at the flow rate of 1.0 ml/min,the detec-tion wavelength was 280 nm,the temperature was 25 ℃ and the volume was 10 μl. RESULTS:The microscopic identification showed microscopic characteristics of C. moutan and C. dictamni,and characteristics of A. sinensis,R. cordifolia and G. fructus were identified by TLC;the linear range of paeonol was 0.106 24-2.124 8 μg(r=0.999 9)and baicalin was 0.059 04-1.180 8 μg (r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 2.06%;average recoveries were respective-ly 101.56%(RSD=1.68%,n=9)and 100.16%(RSD=1.13%,n=9). CONCLUSIONS:The method is simple,accurate and re-producible,and can be used for the quantity control of Chushi pill.

OBJECTIVETo explore evaluation strategies for middle ear dysfunction in cleft palate patients, to optimize the diagnosis and treatment of this dysfunction, and ultimately to improve the comprehensive treatment of cleft palate.

METHODSThe relationship among abnormal tympanic types (B, C, and Anomaly), effusion rate, tympanic pressure, and hearing loss were analyzed. We collected relevant information on 469 ears of cleft palate patients and traced one-year longitudinal changes in the tympana of 124 ears from 62 patients with both cleft lip and cleft palate.

RESULTSThe effusion rates of cleft palate patients with type B, type C, and type Anomaly were 50.3% (97/193), 34.8% (8/23), and 20.9% (53/253), respectively. The tympanic pressure of the ears with and without effusion showed no significant difference (P>0.05). The hearing loss in type B cleft palate patients with middle ear effusion was worse than that in patients without effusion (P=0.001). However, the hearing loss in type Anomaly showed no difference (P>0.05). The constituent ratio of each tympanic type remained constant during the period between cheiloplasty and palatoplasty for cleft lip and palate patients (P>0.05).

CONCLUSIONCleft palate patients of all tympanic types may all suffer from middle ear effusion at different rates. Examination by centesis is suggested for ears with abnormal tympanic types. Early aggressive therapy is essential for type B cleft palate patients with middle ear effusion to avoid hearing loss. However, catheterization may be not necessary for type Anomaly patients, and conservative observation should be performed instead. Myringotomy with grommet insertion during palatoplasty does not delay treatment timing for patients with both cleft lip and cleft palateg.

With the wide application of acupuncture in the world, the research results of neurosciences have made scientific approval on some of efficacy and mechanism of acupuncture, and the concept of western medical acupuricture (WMA) is gradually developed. During the spread of Chinese acupuncture into western countries, WMA is an adaptive improvement when facing basic theories of western medicine including anatomy, physiology and pathology as well as evidence-based medicine system. WMA which is based on theory of muscle trigger point has obvious efficacy on muscular fasciae pain, which attracted wide attention. But when Chinese acupuncture spreads into western world, the theories of Chinese acupuncture such as meridian and specificity of acupoint are questioned due to the results of western clinical study. In this paper, the origin, theory development, stimulating location and method, and categories of diseases of WMA are compared with Chinese acupuncture, and the enlightenment of this difference on Chinese acupuncture research is analyzed.
