With the development of modern medical science and technology,especially modern assisted reproductive technologies,the natural attribute of human reproductive behavior is being increasingly eliminated by its social attribute.The quantity and quality of reproduction have direct influence on the status of social existence and development,thus human have made more and more interfere in human reproductive behavior for social benefits by controlling the demand of childbearing,changing the manner of reproduction,and designing and choosing the result of childbearing.The interference is eliminating the connection of reproduction and sexes,and breaking the original stable social relation based on natural order.While the nature attribute of human reproductive behavior is being eliminated,the urgent problem facing modern people is how to rebuild the stability of social order.

AIM: To evaluate effects of rutecarpine on the movements of gastrointestinal tract in experimental animals. METHODS: In mice, the accelerated movement model of intestinal transit was induced by neostigmine, and metoclopramide or apoplon was applied to induce the accelerated gastric emptying movements. Acetylcholine or histamine was used to induce the contractions occurring in the isolated ileum from guinea pigs. RESULTS: Rutecarpine inhibited normal intestinal transit and demonstrated more effective suppression on the accelerated movement induced by neostigmine in mice; meto- clopramide and apoplon induced-accelerated gastric emptying movements were also significantly inhibited by rutecarpine in a dose-dependent manner. Meanwhile rutecarpine significantly inhibited the isolated ileum contractions induced by acetylcholine or histamine. CONCLUSION: Rutecarpine is an effective inhibitor to intestinal motility and this activity is probably mediated by its antagonistic effects on the cholinergic nerve or its responsible modulations.

Objective To discuss the surgical methodology for sunken upper eyelid and its curative effect by eyelid orbital fat reset.Methods 26 patients with the sunken upper eyelid were operated,in which blepharoplasty incision was used to open musculus orbicularis oculi and septum orbitale,dissected levator,displaced orbital fat were extended and replaced to the sunken region of upper eyelid,to mild-to-moderate ptosis evator tendon membrane folding suture was carried out at the same time and the wound was routinely sutured through 7-0 nylon thread.Results All cases were followed up for 12 months after operation.There was no obvious complication occurred,All cases got ideal outcomes,with smooth and symmetry lid folds.Conclusions The postoperative effects of upper eyelid orbital fat reset for correction of eyelid sunken are satisfactory,without inequality complications,and therefore it is worth promoting.

AIM: To evaluate its pharmacodynamic effects of zhi-chuan-ling (ZCL) oral liquor, a traditional Chinese medicinal prescription, on asthma. METHODS: Asthma models of guinea pigs were established by aerosol inhalation of mixed solution of histamine and acetylcholine for the observation of effects of ZCL on the latent period of asthma attack. Some other indices were also investigated including the contraction of smooth muscle strips isolated from the trachea or intestinum ileum, and variations of the tracheal volume and the bronchotracheal perfusion in guinea pigs. RESULTS: ZCL elongated the latent period of asthma attack induced by areol inhalation of mixed solution of histamine and acetylcholine, antagonized activities against the contraction of the trachea and intestinum ileum induced by histamine or acetlcholine, and increased the tracheal volume and the bronchotracheal perfusion in ginea pigs in vitro. CONCLUTION: ZCL can reduce airway hyperresponsibility, relax bronchospasm, remit ventilation disturbance, and improve ventilatory function by its biologic activities against acetlcholin and histamine.

To find the rule of alterations in AFP mRNA concentration in peripheral blood in patients with hepatocellular carcinoma(HCC) before and after the treatment with transhepatic arterial chemotherapy and embolization(TAE), 15 cases of the pateints with HCC were included in this survey. The AFP mRNA concentration in peripheral blood of the patients were investigated using compatitive RT PCR technique before and 1,2,3,4, 5,6,7, 14, 28 days after TAE. The results showed that AFP mRNA concentration on the third day after TAE was the highest. It declined to the level before treatment during one week.It suggested that AFP mRNA concentration changed with a rule, and following the rule, preventive measure to distant metastasis could be instituted in clinical work.

Objective To evaluate the value of non invasive examinations in the diagnosis of vascular disease of lower extremity. Methods Segmental systemic pressure (SEG), pulse volume recorder (PVR) and continuous wave (CW) were adopted to examination of 36 patients with arterosclerosis obliterans of lower limbs, and the foundings were compared with that of MRA and operation . Results In all 36 cases, non invasive examinations detected abdominal aorta and common iliac artery with femoral artery occlusion in 12 cases ,femoropoplitea artery occlusion in 28 cases, popliteal artery and the distal artery occlusion in 16 case; MRA together with operation confirmed abdominal aorta and common iliac artery with femoral artery occlusion in 11 cases, femoropopliteal artery occlusion in 32 cases and popliteal artery and the distal artery occlusion in 13 cases. The accurent diagnosis rate of non invasive examination was 85.7%. Conclusions Although PVR has not yet been used to replace the arteriography to directly observe the local situation of arterial lesions , it can preliminarily determine the obstruction sites and severe degree of the occluded arteries. PVR has convenient and reliability in the diagnosis,evaluation of the therapeutic effect and the postoperative follow up of blood vessel diseases,it is worthy to be widely applied in the clinical practice.

Objective To study the effect of flee radical on kidney repedusion injury caused by infra-renal abdominal aorta occlusion in rat model and its possible mechanism. Methods Forty-two healthy Wis-ter rats were randondy divided into 6 groups as following ( n = 7) : the control group( sham group) ; simply isehemia 5 h without reperfusion( group I) ; 2 hours reperfusinn following ischemia 5 h ( I/R 2 h), 4 honrs reperfusion following isebemia 5 h ( I/R 4 h), 8 hours reperfusinn following ischemia 5 h( I/R 8 h) and 12 hours reperfusion following ischemia 5 h ( I/R 12 h). In each group the rats were killed to obtain samples of blood and kidney at the specified time points. The contents of BUN, Cr, MDA, SOD in blood and in renal homogenate were measured in each group. We observed the morphological changes of kidney and muscles of lower limb by light microscope. Results BUN level of serum in model group I, I/R 2 h, I/R 4 h, I/R 12 h were higher obvionsly than those of control group, which were maximal in I/R 4 h, then decreased. MDA level of plasma in model group I, I/R 2 h, I/R 4 h, I/R 8 h, I/R 12 h groups were higher obvionsly than those of control group, which were maximal in I/R4 h group, then decreased. SOD level of plasma in model I/R 4 h, I/R 8 h groups were lower obviously than those of control group; SOD level of renal homogenate in model group I, I/R 2 h, I/R 8 h, I/R 12 h groups were higher obviously than those of group I/R 4 h, which were minimal in I/R 4 h group, then increased. By light microscope: The injury degree of kidney and muscles of lower limb in ischemia group was slight, the injury degree of repedusion group was severer than ischemia group. Conclusion The kidney repedusion injury caused by infrarenal abdominal aorta occlusion in rat model might be concerned with the increase of lipid peroxidatian damage after ischemia-repedusion in-jury of lower limbs.

ObjectiveTo explore the value of CT virtual endoscopy in the treatment strategies in low rectal cancer surgery.MethodsFifty- seven cases of rectal cancer in Jining First Hospital were collected,preoperative rectum CT virtual endoscopy,detailed records of patients with rectal invasion and the circumstances surrounding lymph nodes were investigated.Differences were compared in patients after routine pathological examination.And the distance of the tumor from the anal margin was compared with the preoperative rectum on rectal examination and rectal CT virtual endoscopy.ResultsPreoperative rectum CT virtual endoscopy had no significant difference in evaluation of metastases of the surrounding lymph nodes.Compared with postoperative pathological examination( x2 =2.5,P ＞ 0.05 ),while had significant difference in evaluation in perirectal infiltration( x2 =4.44,P ＜ 0.05 ).Rectal examination and rectum CT virtual endoscopy had no significant difference judgement of the tumor from the anal margin ( P ＞ 0.05 ).ConclusionsCT virtual endoscopy has a great significance in the preoperative evaluation of rectal cancer surgical treatment strategies,which should be further studied.

Objective To investigate the value of Adobe Photashop images software in the verifica-tion of radiation portal. Methods The portal and simulation films or CT reconstruction images were impor-ted into computer using a scanner. The image size, gray scale and contrast scale were adjusted with Adobe Photoshop images software, then image registration and measurement were completed. Results By the com-parison between portal image and simulation image, the set-up errors in right-left, superior-inferior and ante-rior-posterior directions were (1.11 ± 1.37) mm, (1.33 ± 1.25) mm and (0.83±0.79) mm in the head and neck;(1.44±1.03) mm,(1.6±1.52) mm and (1.34±1.17) mm in the thorax;(1.53±0.86) mm, (1.83 ± 1.19) mm and (1.67 ± 0.68)mm in the abdomen; (1.93 ± I. 83) mm, (1.59 ± 1.07)mm and (0.85 ± 0.72)mm in the pelvic cavity. Conclusions Accurate radiation portal verification and posi-tion measurement can be completed by using Adobe Photoshop, which is a simple, safe and reliable method.

Objective To discuss the necessity and rationality of regional pancreatoduodenectomy combined vas-cular reconstruction in the treatment of chronic pancreatitis with lump in the head. Methods Thirteen patients who suffered from pancreas with lump in the head, were operated in our department from January 2000 to March 2006. The clinical data were analyzed retrospectively,there were 10 men and 3 women with an age ranging from 37 to 71 (mean = 51 ), all the patients underwent pancreatoduodenectomy combined PV and SMV reconstruction. Results All thirteen patients were pathologically confirmed chronic pancreatitis without postoperative deaths, in which stom-ach empty disorder and pancreatic fistula occurred and were cured conservatively in one case. All the 13 patients who were followed up 19～86 months had no pain and jaundice at all after the operation. Conclusion Combined vascular reconstruction to treat the lump in the head of the pancreas that packages blood vessel and hard to separa-tion is proved to be a safe and reliable method, being capable of raising lump resection rate, which can improve quality of life of patients remarkably to avoid omit minimum cancer in lump to result in lose the curative opportunity.
