Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

Objective To study the mechanism of mast cell increase in cellular leiomyoma of uterus.Methods Tissue sections from 30 cases of cellular leiomyoma of uterus,15 cases of leiomyosarcoma and 30 cases of ordinary leiomyoma were studied using immunohistochemical double labeling techniques.The expression of mast cell tryptase ahd Ki-67 as well as mast cell tryptase and chemotactic factors RANTES,Eotaxin,monocyte chemoattractant protein-1(MCP-1),transforming growth factor-? (TGF-?)were double immunostained.Results Ki-67 in mast cells was rarely expressed in each group. Expressions of regulate upon activation normal T cell expressed and secreted(RANTES),Eotaxin and TGF-? in cellular leiomyoma were 78%,89%,91%,respectively.They were all higher than those in ordinary leiomyoma and leiomyosarcoma(P

Objective To investigate the effect of local injection of Botulinum toxin type A(BTXA) on spasticity and function of the affected upper limb in stroke patients.Methods A total of 32 stroke patients were re- cruited and randomly divided into two groups:a BTXA group and a control group.All the patients had spasticity of upper limb muscles,which scored grade 2 to 3 with the Modified Ashworth Scale(MAS) ,and decreased elbow joint range of motion.The 16 patients in the BTXA group received BTXA injection in the biceps brachii muscles and flexor muscles of forearm on 10～15 points,while those in the control group did not.All the patients in both groups were treated with rehabilitation training techniques.The MAS,Fugl-Meyer upper limb function assessment and Barthel In- dex were employed to evaluate the changes of muscle tone,upper limb function and activity of living (ADL)perform- ance of the patients before injection and at 1st,2nd,6th 12th weeks after injection.Results The therapeutic effect between the BTXA group anti control group was significantly different in terms of biceps muscle tone,the scores of Fugl-Meyer upper limb function assessment and Barthel Index.Compared with preinjection,muscle tone was de- creased significantly and ADL performance was improved after injection in BTXA group.The effects of BTXA lasted more than 12 weeks.Conclusion Intramuscular muhipoint injection of BTXA was useful in reducing muscle spas- ticity,and was helpful for increasing motor ability of the affected upper limb and ADL performance of the stroke pa- tients.

OBJECTIVEThis aimed to investigate the effect of specific sequence oligodeoxynucleotide MT01 on the biological properties of osteoblasts invaded by Porphyromonas gingivalis (P. gingivalis ) by evaluating proliferation, cell cycle, and apoptosis.

METHODSMG63 osteoblasts were recovered and incubated with MT01, CpG ODN, metronidazole (MNZ), and gentamicin (GEN) for 3 h. P. gingivalis (the multiplicity of infection was 100:1) was added subsequently and cocultured for another 24 and 48 h. Cells with PBS comprised the blank group, whereas cells with P. gingivalis comprised the negative controls. Six experimental groups were established: PBS group, P. gingivalis group, MT01+P. gingivalis group, CpG ODN+ P. gingivalis group, MNZ+P. gingivalis group, and GEN+P. gingivalis group. The proliferative ability was measured by methyl thiazolyl tetrazolium assay, and the percentages of apoptosis and cell cycle were examined by flow cytometry.

RESULTSCompared with the blank group, proliferation increased significantly in the MT01+P. gingivalis group (P < 0.05). The ratio of cells was lower at the G₁ phase and higher at the S phase in the MT01+P. gingivalis group compared with the results in the P. gingivalis group (P < 0.05). Early cell apoptosis in the MT01+P. gingivalis group was significantly lower than that in the P. gingivalis group (P < 0.05).

CONCLUSIONMT01 can promote the proliferation, reduce the ratio of the G₁phase, increase the ratio of the S phase, and inhibit the early apoptosis of osteoblasts invaded by P. gingivalis.
