Objective:To investigate the abnormity of arterioles in gallbladder and its relation with gallbladder hypomotility in patients with gallstone and diabetes mellitus.Methods:30 patients with simple gallstone and 30 patients with gallstone accompanied with diabetes mellitus were analyzed.Their gallbladder emptying function was measured with B ultrasound before operation.After operation,the arterioles of gallbladder rinsed with PAS reagent in photos were analyzed in tubular area and stereo system with BEIHANG CM-2000B biological and medical photo system.Results:The gallbladder volumes of fasting(V 0),two hours after eating(V 2) increased (59.3?0.6 vs 37.9?5.4,44.7?6.6 vs 14.3?4.9 respectively),whilethe ejective volume of bile(EV) and the ejective rate of gallbladder two hours after eating[GBEF 2 (%)] decreased in patients with diabetes mellitus(14.5?7.1 vs 23.4?9.3,24.9?12.7 vs 61.5?8.5,respectively).In patients with gallstone and diabetes mellitus,the area ratio of arterioles wall to whole arterioles in cross section was significantly higher than in the patients with simple gallstone(0.81 ?0.09 vs 0.58?0.15, P 0.05).Conclusion:The emptying function is significantly impaired in patients with gallstone and diabetes mellitus.The sedimentation of PAS positive material in the wall of arterioles lead to the stenosis of arterioles,and it is probably the cause for gallbladder hypomotility.

Bile dut injury (BDI) is one of the severe complications of laparoscopic cholecystectomy (LC).The classification,diagnosis and treatment of the BDI caused by LC are partly controversial.The most efficient classification of the BDI is Strasberg-Bismuth's classification and the three modes and four classes developed by the Biliary Surgery Group of Surgery Branch of Chinese Medical Association.Although the success rate of intraoperative diagnosis for the BDI is very low,in most cases,the BDI is diagnosed by clinical manifestations and assistant examinations.Accurate classification and early diagnosis could help us to make a specific one for each patient according to certain situation.In this review,we focus on the classification,diagnosis and treatment of the BDI caused by LC.

This article summarizes 32 cases of the SCI patients suffered from bladder stones.Respects relating to causes,characteristic,diagnosis,treatment and prevention of bladder stones after SCI are discussed in the article.In order to decrease or avoid complication of indwelling urethral catheter,the patients with neuropathic bladder dysfunction are treated by intermittent catheterization.If it is necessary for SCI patients to indwell urethral catheter,we must strengthen management of the catheter and renew a catheter in time(once a week).

Objective To investigate the way of resection of high-sacrum tumors and the reconstruction way of the sacrum. Methods From October 2001 to October 2005,7 patients with high-sacrum tumors were enrolled. After resection, the pelviclring were recormtmcted with Chinese Great Wall pedicle screw system and fibulae graft,corresponding chemotherapy and radiotherapy were given after operation. Results The short-term results were satisfactory with the lumbosacral pain reduced and the neurological function improved in different degrees, however dysuria occurred in 1 ease and 1 case cerebrospinal fluid leakageand 1 case postoperative infection and delayedunion among the 7 eases in this group. In the follow-up period of 6 months to 3 years,4 eases died for tumor recurred or metastasis. Conclusions Surgical procedure,reconstruction of the sacrum and postoperative comprehensive treatment have important effects on the prognosis. Meanwhile,it is operative key to lessen operative hemorrhage,reserve the function of caudal equine and rebuild weight high post function of the pelvis after superior sacrum tumor is removed.

Hepatocellular carcinoma(HCC)is a common world wide disease.Transcatheter arterial chemoembolization(TACE)has been the first choice for the unresectable midadvanced ones.However, TACE has its own limitation such as high recurrence rate and many complications, what's more, recurrence induced by neovascularization which is stimulated by activation of vascular endothelial growth factors promoted by ischemia and hypoxia in local tissues after the embolization always reduce the effect of treatment.And combination of TACE and anti-angiogenesis therapy is capable to make up the shortage of each other and reduce the recurrence rate, which has been a hot issue for non-surgical treatment of HCC.

Objective To study the role of HMGA2 in the occurrence and the progression of uterine leiomyomas.Methods Fifty cases of uterine leiomyomas who met the inclusion criteria(aged 30-50 years old,free from hormone at least for 6 months before surgery,no other diseases,postoperative pathological diagnosis as uterine leiomyoma) admitted to our hospital from January to July 2003 were studied.The expression of HMGA2 mRNA in uterine leiomyomas and neighbour normal myometrium was detected by ISH.Results HMGA2 mRNA was strongly expressed in 30 cases of uterine leiomyomas but not expressed in neighbour normal myometrium.There was no difference in HMGA2 mRNA between proliferative stage and progestational stage.Conclusion The increased expression of HMGA2 in uterine leiomyomas may be important in the occurrence and the progression of uterine leiomyomas.

Objective To investigate the effect of gadolinium chloride (GdCl3) on the H22 experimental hepatocarcinogenesis in mice. Methods Totally 80 mice were inflicted to experimental hepatoma by implanting H22 cells to their liver lobes, and then equally and randomly divided into experimental hepatoma group (B) and GdCl3 pretreatment group (10 mg/kg, C). Another 40 mice served as normal control group (A). Ten mice from every group were killed respectively 7, 14, and 28 d after implantation. The left 10 mice were used for recording survival time and measuring the mass weight. Hepatic pathological histology was observed, and the expression of TNF-? was detected by ELISA and RT-PCR. Results ①Survival time was obviously higher in group B than in group C (P

This paper presented the relationship between age and Ⅹ—ray signs in metacarpophalanges of children's hands with Kashin—Beck disease. The result showed that Ⅹ—ray signs of metaphysis in metacarpophalanges of children were decreased with age ,but the types and the positive rate of Ⅹ—ray signs in the distal end of bones ,epiphyses and carpals were increased with age. The authors consider that articular lesions in Kashin—Beck disease will be more serious and enlarge with age.

Objective To investigate the renoprotective effects of KB-R7943 on renal injury induced bycontrast media. Method Tubular epithelial cells were trested with varions cencentration of KB-B7943 (10-5,10-6 mol/L) for 12 hours before contrast media was used. After cells we, re incubated with contrast media (CM)(110 mgI/L) for 1 hour, cells injury was assessed by using LDH, and cell morphologic changes and cells apopto-sis were evaluated with inverted microscope and flow cytometry, respoelively. Intracellular Ca2+ and reactive oxy-gen species (ROS) were analyzed by using confocal microscope. The expression of Na+/Ca2+exchanger mRNAwas evaluated by RT-PCR. Mannitol with same osmolarity (20% mannitol, 770 mOsm/L) of CM was used as con-trol. One-way analysis of variance and q-test were used for comparison between groups. The simple linear correla-tion was employed to analyze the correlation. P < 0.05 was considered significant. Results Contrast media sig-nificantly induced tubular cells damage significantly and apoptosis at 1 hour after incubation, meanwhile, intracel-lular Ca2+ and ROS were inoreased progressively in CM group. KB-R7943 significantly attenuated cells damage andapoptosis in dose-dependent in association with decreased intracellular Ca2+ and ROS. Expression of Na+/Ca2+exchanger mRNA was not changed. Conclusions KB-R7943 has renoprotective effects on the contrast-media-in-duced renal tubular cyotoxicity
