Basic research and clinical research on multiple myeloma (MM) have extensively progressed, as proven by the change in the definition of complete response (CR). With improvements in laboratory technology and introduction of novel agents, CR particu-larly emphasized both micro-and macro-models. The development of CR yielded therapeutic advances in MM and vice versa. The defi-nitions of response and treatment strategies were closely connected and improved. A need exists for further detailed studies on long-term disease control, such as optimal combination of agents. Given the shortage of new drugs and the distinctiveness of health in-surance, Chinese doctors should select the best treatment projects based on real-life situation in China.

Objective To observe the variations and distribution of the pulmonary fissures of normal subjects in China on multi-planar recontruction (MPR) images of 64- slice helical CT.Methods A total of 1235 subiects underwent 64- slice helical CT scan with a slice thickness of 0.6 mm.The MPR images were observed to find normal interlobar fissures and the variations including the accessory fissures occurred in lobar or segmental lungs.Results Of the all cases,no variation was seen in 80.08%(989/1235),and pulmonary fissure variations occurred in the remaining 19.92%(246/1235).Among pulmonary fissure variations,20.33% (50 cases) occurred bilaterally,with the other 79.67%(196 cases) unilaterally.Of the unilateral pulmonary fissure variations,63.01%(155 cases) was seen in right lungs,and 16.66% (41 cases)was found in left lungs.There was neither oblique nor horizontal fissure in 1.22%(3 cases) of right lungs.Absence of oblique fissure happened more frequently in left lungs (6.91%,17 cases) than right lungs(3.65%,9 cases).Incomplete oblique fissure happened more frequently in left lungs (8.53%,21 cases)than in right lungs(4.06%,10 cases).Totally,absence of the horizontal fissures were found in 27.24%(67 cases) of the subjects,and incomplete horizontal fissures were found in 9.76% (24 cases).Accessory fissure were found in 83.33%(205 cases) of the subjects,and they happened more frequently in right lungs than in left lungs(53.66%,132 cases on the right,while 29.67%,73 cases on the left).Accessory fissures on right lower lobe and segments happened much more than on the left(40.65%,100 cases on the right,while 7.72%.19 cases on the left).Lingular fissures in the lungs were found in 15.85%(39 cases).The changes in shape and location of the oblique and horizontal fissures were found in 41.06%(101 cases),and happened more frequently in right lungs than left lungs (35.37%,87 cases on the right,5.69%,14 cases on the left).Conclusions Sixty-four-slice helical CT with MPR can clearly display pulmonary fissures and their variations,and it can distinguished small lesions from small vessels.

we examined the serum copper level in 125 pregnant women (83) normal pregnant women of 28～40 weeks of pregnancy; 12 patients with se-vere edema-proteinurine-hyperterision syndromeduring 37～40 weeks of pregnancy; 30 patientswith prolonged pregnancy) and compared it withurine E/C value and Apgar score in order to deter-mine the reliability of serum copper value in diag-nosing placental insufficiency. The results con-firmed that the serum copper value was increasingwith the growth of weeks of pregnancy, but it wasdecreasing after the fortieth week of pregnancy.Comparison of the serum copper value with theurine E/C value showed that when the E/C or = 10. And when the Apgar score7. These results indicatethat the serum copper value can serve as an indexof placental function in the third trimester of preg-nancy.

Objective To study the feasibility and morphological characteristics of wide caliber of local biliary tract constructed by increasing pressure of local bile duct in a short period of time.Methods Twelve mongrel dogs were randomized into 2 groups.In group A,only inlaid bile duct dilator(IBDD)was placed for biliary drainage in common bile duct.In group B,IBDD was placed in tommort bile duct for biliary drainage and dilated it through affusing 0.1 ml,0.1 5 ml,0.2 ml and 0.25 ml water on postoperative day 1,8,15 and 22,respectively.The expandable ballbladders were kept on being dilated with increasing pressure for a month.Total bilirubin(TB),alanine aminotransferase (ALT),aspartate aminotransferase;aspartate transaminase(AST)of serum,bile duct diameter (BDD),histologic changes of biliary duct wall and hepatic tissue,and postoperative biliary tract contrast were determined before and after operation in both groups.Results There was no significant difference in TB,ALT,AST and histologic changes of hepatic tissue in bilary predilation and postdilation of each group and between group A and group B.There was great difference in BDD in bilary predilation and postdilation of each group and between group A and group B.In group B,the biliary wall was thickened and the lumina of bile duct widened,favorable tenacity of broaden biliary tract was shown.The specific staining of the broadened biliary wall showed that collagen and elastic fibers compacted fine and close and there was no breakage.Conclusion Dilated local bile duct constructed by increasing internal pressure of local bile duct has thick wall,wide caliber and its collagen and elastic fibers compact fine and close.This provides condition to supply early-stage cholangio-jejunostomotic reconstruction of bile duct iniury and create wide stoma for cholangio-jejunostomy in dogs.

Objective To study the curative effect of posterior diskoscope discectomy for adolescent lumbar disc herniation.Methods Eleven adolescent patients with lumbar disc herniation were treated with posterior diskoseope discectomy,the Japanese orthopaedic association (JOA) lower back pain score was observed and compared before operation and after operation 3,6,12 months.Results The JOA lower back pain score were (15.45 ± 2.73),(27.18 ± 2.08),(28.18 ± 1.25),(28.54 ± 1.21) scores before operation and after operation 3,6,12 months,there was statistical difference in JOA lower back pain score between before operation and after operation 3,6,12 months (P ＜ 0.01).The patients were followed up for 1-10 years,mean 7.9 years,excellent was in 8 cases,good was in 2 cases,general was in 1 case.Recurrence and iatrogenic lumbar instability were not found.Conclusions The posterior diskoscope discectomy with less trauma,less bleeding,faster recovery,and can achieve the same decompression objective with the traditional open surgical.So posterior diskoscope discectomy can be used as adolescent treatment of lumbar disc herniation.

Objective To study the analgesic sites and mechanism of total alkaloids in Papaver nudicaule (TAPN). Methods The sites of analgesic action of TAPN were observed by adopting Formalin test and two different routes of intracerebroventricular (icv), intrathecal (ith) in mice and rats and comparing ED 50 of TAPN in writhing reaction in mice induced by acetic acid by ip and iv administration. Results TAPN significantly lowered pain score of the early and late phase of Formalin response and was more sensitive in the late phase. Inhibition of TAPN at the same dose by ip administration in writhing reaction in mice induced by acetic acid was stronger than that by iv. The ED 50 value of TAPN at any time by ip administration was lower than that by iv administration. By means of central microinjection, TAPN by icv administration induced remarkable analgesic effect in mice, but TAPN by ith administration had no significant analgesic effect. Conclusion The sites of analgesic action of TAPN are mainly at periphery. TAPN has also central analgesic effect, and the site may be at the level above the spinal cord.

Objective To study the relationship between analgesic effect of total alkaloids in Papaver nudicaule(TAPN) and prostaglandins(PGs) with opium receptors.Methods The analgesic effect of TAPN was studied by hot-plate, writhing,electric-evoked methods of mice.The analgesic mechanisms of TAPN and PGs with opium receptors were studied by the writhing numbers induced by different substances(Ach,AA,MgSO_4),the PGE_2 level in celiac fluid in mice after treated by AA writhing test and the antagonistic experiment of Naloxone.Results The inhibitory effect of TAPN on the writhing induced by Ach and AA in mice was stronger than that induced by MgSO_4.TAPN could also lower the PGE_2 level in celiac fluid.In the antagonistic experiment of Naloxone,no antagonism to the analgesic effect of TAPN had been found by ip or icv Naloxone.Conclusion It may be the mainly peripheral analgesic mechanism that TAPN could lower the PGE_2 level in celiac fluid.Its central analgesic mechanisms are not related to opium receptors.

Objective To produce the experimental pig model of obstructive sleep apnea hypopnea syndrome(OSAHS) through raising pigs in the lower pressure container in order to study the effect of low pressure on morphology of upper respiratory soft tissue in pig.Methods The pigs were living in a container of low pressure for 6 months to make up the pig models of OSAHS.When the symptoms like OSAHS appearing and the pharyngeal respiratory pressure changing like the characteristics of OSAHS,the pigs were scanned by CT and compared with controls.Results The pharyngeal rear wall and soft palate in model pigs were thickened(0.94 cm?0.16 cm and 1.06 cm?0.23 cm respectively),while in control groups were(0.60 cm?0.11 cm and 0.59 cm?0.13 cm respectively).The cross-sectional area of upper airway in anterior,middle and rear parts were(1.49?0.12) cm2,(1.37?0.32) cm2 and(1.00?0.21) cm2 respectively,the narrowest part was in rear area,and in control groups were(1.30?0.14) cm2,(1.57?0.32) cm2 and(2.48?0.42) cm2 respectively.Conclusion The lower pressure condition can be used to produce animal experimental model of OSAHS,the low pressure is the important factor to cause OSAHS.
