Objective To study the phenolic compounds from Sagina japonica. Methods The separation and purification were carried out by silica gel Sephadex LH-20 gel and RP C-18 colomn chromatography. The structures were identified by spectra. Results Nine phenolic compounds were isolated from S. japonica. They were identified as:p-E-methoxy cinnamic acid methyl ester (Ⅰ),umbelliferone (Ⅱ),7-methoxy coumarin (Ⅲ),5,7-di-hydroxy coumarin (Ⅳ),5,7-di-methoxy coumarin (Ⅴ),cerarvensin-7-O-glucoside (Ⅵ),5,7,2'-trihydroxy-8-methoxy flavone (Ⅶ),5,7-di-hydroxy-8,2'-di-methoxy flavone (Ⅷ),5,7,3',4'-tetrahydroxy-6-methoxy flavone (Ⅸ). Conclusion All of these compounds are first isolated from S. japonica.

[Objective]To discuss the initiating and developing mechanism of OPLL,and the influence of different operations on happening and developing of OPLL.[Method]We subgroup healthy adult S-D rats into groups,did operation on C 3~6 level.The first group:laminectomy;the second group:laminectomy and muscle cutting;the third group:muscle cutting only;the fourth group:exposure only;contrasting group:no treatment.We got the tissue of posterior longitudinal,ligament at 1,2,4,and 8 weeks post-operation and quantify BMP-2 and BMP-7 by PCR method.[Result]BMP-2,BMP-7 increased significantly in the 1st,2nd and 3rd group compared with the contrastinggroup;BMP-2,BMP-7 of only exposure group had no significant difference compared with the contrasting group.[Conclusion]BMP-2 and BMP-7 play important roles in the early stage of OPLL,they could be the on-setting factors of OPLL.BMP-7 may play an important roles in the later ossification period.

Objective To define the indications of direct transpedicular lag screw to treat traumatic spondylolisthesis of axis (Hangmans fracure) and to evaluate the result of the technique. Methods From February 1998 to December 2000, 22 patients with acute traumatic spondylolisthesis of axis were treated. Ten of them achieved anatomic reduction by skull traction but no acceptable stability was ensured by traction alone. Among the ten patients, eight had integral and normal shaped C2 vertebral bodies (6 male, 2 female; age ranged from 18 to 42 years with an average of 28.2 years; 5, 2 and 1 patients classified as type Ⅰ, Ⅱ and Ⅱa injuries respectively according to Levine-Edwards classification and graded as D spinal injury in 2 cases and E in 6 cases according to Frankel scale) were further fixed with transpedicular lag screw. Under general anesthesia, the patients were laid in prostrate decubitus in a prepared head-neck-chest ventral plaster plate with skull traction in place to maintain reduction and lateral image intensification was applied to confirm the reduction. A posterior midline incision from C1-C3 was performed, and soft tissue was released to expose clearly the lamina, lateral mass, superior and medial aspect of the C2 pars interarticularis (isthmus plus pedicle). Points of entry for screw insertion were located at the entrance at the posterior aspect of lateral mass. The drill bit is parallel to both of the medial and superior border of C2 pars interarticularis (usually 25?-30? cephalad to the transverse plane and 30?-35? medial to the sagittal plane). The screw hole in the posterior cortex was overdrilled with a 3.5 mm drill bit for interfragmentary compression. 3.5 mm screws (25-30 mm, determined by depth gauge) were drived in after the cortex being tapped with a 3.5 mm tap. The whole procedure was done under monitoring of "C" arm fluoroscopy for safety and accuracy. Results It costs an average of 70 minutes to finish the procedure with mean blood loss of 250 ml. Hospital stay was about 18 days. A mean follow up time of 14 months (11 to 18 months) didnt confirm any early or late postoperative complications, all cases gained bony union 3 months later with complete neurological function recovery. The range of neck rotation was restored normal with no C2,3 instability or screw loosing found. Conclusion With appropriate indications, transpedicular lag screw fixation provides good reduction and stability to Hangmans fracture. This technique can only be applied to the fractures which are reductable.

Objective To explore the clinical features and operative treatment of chronic bladder entrapment and bowel herniation after traumatic symphysis pubis diastasis. Methods One patient of late pelvic posttraumatic mal-alignment as Tile C2 type, which was associated with serious symphysis separation and combination of chronic bladder entrapment and bowel herniation, was admitted to our hospital in August 2002. The X-ray, three-dimensional CT reconstruction, MRI, and the bladder cystography were performed respectively in order to confirm the conditions. With the usage of ilioinguinal approach, the symphysis pubis diastasis was exposed and restored firstly; then, the malunion site of the left iliac was corrected; finally, after the reduction and internal fixation of the pelvis, the bowel herniation was resolved and the inferior abdominal wall defect was repaired with artificial materials. During the operation, the abnormal conditions were ob-served as follow: 1) The distance of symphysis pubis separation was about 7.5 cm; 2) the full-thick of the ectus abdominis was torn longitudinally tear along the middle line, and the transversalis fascia was fibrosis and adhered to the peritoneum, which consisted of hernia capsule; 3) the small bowel had been entrapped over the bladder through the gap of rectus abdominis and the right Hesselbach triangle. Results The pa-tient was followed up of 6 months. The limb discrepancy had been corrected satisfactory with a sound frac-ture healing and a good gait recovering after operation. The urinary function has recovered with a normal ap-pearance of penis. The patient felt stronger then to relieve the bowels than he did preoperatively. The erected dysfunction did not improve postoperatively. Conclusion The combined osteotomy and rigid fixation through anterior and posterior pelvic ring in the same stage is an effective method to close the symphysis seperation, decrease the volume of pelvic cavity, construct the pelvic floor indirectly, repair the inferior ab-dominal wall defect, cure the bowel herniation, and improve the bladder entrapment.

Tolylene Diisocyanate (TDI) is the important industrial material in producing polyurethane dope. In recent years, with the development of fitment, polyurethane product was widely used. During the procedure in production and usage, TDI is dissociated from polyurethane production and will pollute indoor air. TDI is highly volatile and can irritate the skin, mucous membranes, eyes, nose and throat. The most common and most serious response occurs in the lungs. Thus, in many countries, the limit for TDI has been established and put into practice, in China the work for establishing limit for TDI in indoor air has been doing also. The character of TDI and harmfulness to human, the limit for TDI in indoor air in China and in the other countries, the measurements to control TDI pollution were reviewed in the present paper

The macroscopy and ultrasondgraphy analysis for thirty reseeted specimens of esophageal carcinoma proved by pathology was reported in this paper.The ultrasonic features of esophageal carcinoma as follows:the local wails became thicker,their layers were unclear or disap-peared,the normal walls were insteaded of irregular masses with hypoechoic patterns, the borders of the masses were definite or indefinite,and the posterior echoes of the masses had little change.In addi-tion,the depth of tumor invasion Was compared by the ultrasonography and pathology.The ultrasonic features of the esophageal walls without tumor were also described.

The incidence rate of thyroid cancer is increasing very rapidly during the past years.131I treatment for DTC is an effective method.However,DTC refractory to 131I treatment or therapeutic failure is not uncommon.High level expression of nuclear factor-kappa B (NF-λB) in thyroid cancer is closely related with carcinogenesis,progression,anti-apoptosis and therapeutic resistance.NF-κB inhibitor was effective for the treatment of thyroid cancer.Combined NF-κB inhibitor with131I may improve the therapeutic efficacy.

Objective To observe the clinical efficacy of thread embedding plus Chinese medication in treating primary dysmenorrhea due to blood stagnation caused by cold accumulation. Methods Totally 136 patients with primary dysmenorrhea due to blood stagnation caused by cold accumulation were randomized into a treatment group and a control group, 68 in each group. The treatment group was intervened by thread embedding at Shiqizhui (EX-B 8) and bilateral Ciliao (BL 32) plus Chinese medication;while the control group was by Chinese medication alone. The dysmenorrhea symptom score and Visual Analogue Scale (VAS) were observed before and after intervention, and the clinical efficacies were compared. Results The total effective rate and recovery-markedly effective rate were respectively 93.8%and 78.1%in the treatment group, versus 85.2%and 50.0%in the control group, and there was a significant difference in comparing the recovery-markedly effective rate (P<0.05). After intervention, the dysmenorrhea symptom score and VAS score were significantly changed in both groups (P<0.01);there were significant differences in comparing the symptom score and VAS score between the two groups (P<0.05). The half-a-year follow-up study showed that the total effective rate and recovery-markedly effective rate were respectively 90.6%and 68.8%in the treatment group, versus 70.6%and 38.2% in the control group, and the differences were statistically significant (P<0.05, P<0.01). Conclusions Thread embedding plus Chinese medication is an effective approach in treating dysmenorrhea due to blood stagnation caused by cold accumulation, and it’s easy-to-operate and causes less pain.
