1.Expressions of IL-6 receptor subunit gp80 and gp130 genes in bone marrow of osteoporotic rat
Chinese Journal of Endocrinology and Metabolism 2000;0(06):-
Gene expressions of interleukin-6 receptor subunit gp130 and gp80 were investigated by competitive RT-PCR in the rat model of osteoporosis. A significant increase in expressions of gp130 and gp80 was found in bone marrow of osteoporotic rat, this change may be a possible mechanism in osteoporosis due to loss of estrogen.

Objective:To investigate the effect of catgut implantation at acupoint,Compound Erxian Decoction on levels of serum cytokine in ovariectomized rats.Methods:Sixty 3-month-old female Sprague-drawley rats,weighed 230?20g each,were divided into six groups,ten rats in each group.The first group were sham-operated(Sham-G),while the remaining groups,established by excising both sides ovary,were catgut-acupuncture group(CAG),Chinese herb group(CHG),catgut-acupuncture plus Chinese herb group(CCG),estrogen group(EG)and model group(MG).There wasn’t any therapy in sham-operated group and model group.After 12 weeks corresponding therapy,all groups were sacrificed to procure blood serum for testing the contents of E 2 ,GM-CSF,IGF-1,TNF-?by means of radioimmunoassay and both retral thighbone for testing bone mineral density(BMD) and bone mineral content(BMC)in each specimen.Results:The BMD and BMC of thighbone,E 2 and IGF-1 of serum and in CAG,CHG,CCG and EG was compared with Sham-G,there was no significant difference,but which was higher than MG(P

AIM: The synergistic effect of basic fibroblast growth factor (bFGF) and endothelin- 1 (ET-1 ) on rat aortic vascular smooth muscle cells(VSMC) proliferation was observed. The possible mechanism of the synergism was also investigated. METHODS: BrdU incorporation and cell counting method were adopted to value the pro - proliferative effect of VSMC. Western- blotting was used to observe the variation of bFGF and FGFR - 1 isoforms expression. RESULTS: bFGF and ET- 1 could promote VSMC proliferation separately, and synergistically in combination. The synergism was dose - and time - dependent. ET- 1 increased all the three bFGF isoforms and FGFR - 1 protein level in dose - and time- dependent manner. In addition, after exhaustion of intracellular PKC, the upregulation effects of ET- 1 on bFGF and FGFR - 1 expressions in VSMC both inclined. CONCLUSION: bFGF and ET- 1 had synergistic effect on VSMC proliferation. ET- 1 may increase the responsiveness of VSMC to bFGF through modulation of bFGF isoforms together with FGFR - 1, which was PKC - dependent.

Anatomical hepatic segmentectomy is the treatment of choice for hepatolithiasis. However, in consideration of the volume of residual liver and the liver function, anatomical polysegmentectomy of the bilateral lobes for hepatolithiasis is restricted. Protection of the portal pedicles to the segments preserved and avoidance of ischemia/reperfusion injury to the residual liver parenchyma are critical steps during the operation.A female patient with hepatolithiasis and had a surgical history of choledocholithiasis removal and T-tube drainage received ana tomic polysegmentectomy with segments Ⅰ and Ⅳ preservation at the General Hospital of Kunming Medical College. During the operation, Portal pedicles to the segments Ⅰ , Ⅱ, right lobe,and segments Ⅱ and Ⅲ were isolated prior to liver parenchyma transection. Portal pedicles to segments Ⅰ and Ⅳ were protected under direct visualization. Hepatoduodenal ligament occlusion was not applied during liver parenchyma transaction. Segments Ⅱ- Ⅲ and Ⅴ-Ⅷ were anatomically resected, and segments Ⅰ ,Ⅳ were preserved with satisfactory vascularization. The patient recovered uneventfully and was discharged 14 days after the operation.

This paper summarize the perioperative nursing of 12 newborns with thyroglossal cyst. The preoperative nursing measures focused on prone position,gastric tube feeding,close monitoring of vital signs and tracheal intubation as needed. If the TeSO2 was normal,oxygen therapy was not recommended. After the operation,continuously monitoring vital signs,respiratory care and use of sedatives as needed were carried out. As a result,all of the 12 infants recovered and discharged.

Objective To monitor lung growth rule of normal middle-late pregnancy fetal. Methods 599 cases of 18 and 40 weeks normal singletons were grouped by every two weeks. The length of right lung in the sagittal plane and the cross-sectional plane were measured, and the growth curve was described. The ratio of right lung area (RLa) and head circumference (Hc),chest circumference (Tc) and of the chest area (Ta) in different gestational ages was calcalated. The correlation coefficient was obtained by applying statistical analysis. Results There was a linear relationship between RLa/Hc and RLa/Tc and growth of gestational age;the regression equation was:(RLa/Hc: ?Y= 0.948X-1.221, r2 =0.898, the RLa/Tc: ?Y=0.944X-1.800, r2 =0.894). RLa/Ta in different ges-tational age was in constant range:0.42~0.55. The length of right lung in the sagittal plane and the cross-sectional plane increased along with the gestational age, and the growth speed was:before and after diameter(the cross-sec-tional plane) > upper and lower diameter (sagittal plane) > about size (the cross-sectional plane). Conclusion Prenatal ultrasound can evaluate the growth rule of normal fetal lung and provide the basis for assessment of fetal lung maturity.
