Objective To investigate the protective effects of Ulinastatin (UTI) and 1, 6 fructose diphosphate (FDP) on cerebral ischemia-reperfusion injury, and to discuss the protective mechanisms of UT1 and FDP on cerebral ischemia-repeffusion injury. Method Rabbit ischemia-repeffusion injury models were prepared by"four arteries occlusion". All rabbits were divided into four groups (n=6): control group, UTI (10 U/kg) group, FDP (200 mg/kg) group, UTI+ FDP group. Salt water, UTI, FDP and UTI + FDP were respectively used immediately after ischemia-reperfusion. Plasmic MDA and GSH-Px were measured at 30 minutes, 1 hour, 3 hours and 6 hours after reperfusion. Results The concentrations of plasmic MDA in every group were significantly improved compared with those in control group (P0.05 ), but significant difference could be found after 3 hours (P

Objective To analyze the manifestation,reason,the processing method of the steel wire implantation with the sereotactic mammography to improve the accuracy of the preoperative positioning.Methods Seventy-nine cases which got the stereotactic steel wire implantation.In 96 lesions, 13 had steel wire displacement.Among them,5 cases got steel wire displacement during the sereotactic process,5 cases got steel wire displacement after the stereotactic process,2 cases got steel wire displacement during the operation,one case did not show the calcification on the postoperative radiography.Results The steel wire displacement occurred in 5 cases during the stereotactic process came from the patients and doctors respectively and the repositioning was needed.The steel wire displacement after the stereoscopic positioning was attributed to the overdose injection of local anesthesia,which led to the mismatch between the depth of Z axis of the mammary gland and the actual depth the computer given,the incorrect method for needle placement,and,neglecting whether the steel wire have got the lesion anchored when pulling out the needle set of steel wire hood,besides,these three kinds of instances above were all exaggerated by the accordion effect.For the displacement within 2 cm,the lesion can be excised toward the pathological change direction according to the position that steel wire prompted and re-place the second steel wire,putting the J-shaped steel wire into the needle hood and taking it out of the body.After repositioning,2 cases had the steel wire prolapse during operation,which resulted from the over-lifting of the steel wire.After placing the steel wire, the radiologist should give an accurate description on the depth and direction to the surgeon and the notch should be taken for incision from the steel wire head end which is proximate to skin.The postoperative specimen from one case had no calcification,which might be related to the condition that the calcification was located in the gland body,which got destruction from the surgical electrical electrotome.The excisionscope should be extended and the short term reexamination is recommended to make sure the complete excision of the calcification.Conclusion It is the gold standard method that implanting the steel wire with the stereotactic mammography to guide the surgical dissecting technique to diagnose non-palpable breast lesion(NPBL).Thorough understanding of the displacement manifestation of implanting steel wire with stereotactic technique and the treatment methods will be helpful in the surgical dissecting guidance.

ObjectiveTo investigate the hemostatic effect of fibrin sealant (FS) powder on severe wound surface and find out the minimum effective dosage.Methods1 cm2 round wound surface was made on the liver of New Zealand white rabbits. Different dosages of FS powder were administrated on the wound surface. Bleeding time and bleeding volume were examined to find out optimized dosage. Hemostatic effect of FS powder was observed and compared with chitin cotton, gelfoam and normal gauze.ResultsBleeding time (0.57±0.21 min)and bleeding volume (0.35±0.29 ml)of FS 10 mg/cm2 group were obviously different from FS 8 mg/cm2 group (P<0.05), not significantly different from FS 12 mg/cm2 group. FS 10 mg/cm2 group got the shortest bleeding time and the lowest bleeding volume, which was obviously different from chitin cotton, gelfoam and gauze groups (P<0.05～0.01).ConclusionThe hemostatic effect of FS powder is better than gelfoam, chitin cotton and gauze and its optimized dosage is 10 mg/cm2.

OBJECTIVETo explore the clinical effect of combined application of magnetic attachments and extracoronal attachments in prosthodontics.

METHODSTwenty-two cases of dentition defect with isolated residual root or residual crown were selected. All the cases accepted the restorative treatment combined magnetic attachments with extracoronal attachments. The clinical effect of dentures and the condition of abutment teeth were evaluated by chief complaint of patients and clinical examination. The follow-up time ranged from 2 years to 4 years.

RESULTSSatisfactory functional, stable and esthetic results of dentures were achieved for all the cases. And there was no abutment loosening and no secondary caries. Alveolar bone loss around abutment occurred in 1 case, gingivitis of abutments appeared in 5 cases. Chewing pain occurred in 1 case and unstable state of dentures appeared in 5 cases after the use of denture for 2 years. The dentures of above-mentioned cases were used normally after symptomatic treatment.

CONCLUSIONThe combined application of magnetic attachments and extracoronal attachments in prosthodontics is an effective treatment option for cases of dentition defect with isolated residual root or residual crown.

In view of the anatomical and physiological barrier of the ocular surface and the intraocular structure, the conventional ophthalmic agents cannot efficiently reach the lesion site.Currently, the different types of nanomaterials possess great advantages in delivering drugs due to their characteristics of small size, easy preparation, degradability, strong targeting and less irritation to biological tissue.As drug delivery carriers, nanomaterials have been widely used in ocular drug delivery so as to treat different types of eye diseases.In this paper, the applications of nanomaterials as drug delivery carriers in treating eye diseases are briefly reviewed.

Objective To explore the relationship between wild rodent plague and human in wild rodent plague foci of the northwestern area in Yunnan to probe the possible transmission mechanism of wild rodent plague to human. Methods Data of component ratio of rodents and fleas was collected in different areas from 1985 - 1995. Activities and habits of residents regarding the way they keep cats and dogs and parasitic fleas and free fleas indoor were investigated, the dog serum was collected for detecting F1 antibody. Results Eothenomys miletus were main rodents in farmland and shrub, accounting for 48.00% (4753/9902) and 54.50% (4282/7857), Apodemus chevrieri were main rodents in garden, being 50.47% (1332/2639). The component ratio of Neopsylla specialis specialis was 13.31%(229/1720), 12.31%(1678/13 739) and 10.87%(957/8802) respectively in garden, farmland and shrub, higher than in indoor. The component ratio of Frantcpsylla spodix was 39.88% (686/1720), the highest in garden. Thirty-two per cent (32/100) of residents kept cats,in which 63% (20/32) with cat fleas, 68% (68/100) of villages kept dogs, in which 76%(52/68) with fleas. Eighteen parasitic fleas were caught from 43 dogs with a flea index of 0.119 and a rate for fleas of 11.63%, 7 pulex were collected from 17 indoor. Forty-three blood serum samples were obtained from dogs, among which 3 were positive blood serum. Conclusions Residents touch affected animals or media in different situations. The possibility of transmission for wild rodent plague to human exists in loci in a chain of wild rodent plague → fleas or predation → homebred animal plague (cats or dogs) →touching or respiratory → human.

OBJECTIVEIn order to provide scientific basis for introduction breeding and production regionalization of Panax notoginseng, the environment of producing area, agronomic traits and medicinal material output were investigated.

METHODUsing field survey sampling at harvest time, agronomic traits indicators of leaf segment, stem segment and roots segment etc. of commodity P. notoginseng, longitude and latitude, elevation, soil type, landform of producing area were measured and observed.

RESULTThe P. notogiseng cultivation was expanding from traditional area like Wenshang to new areas as Honghe, Kunming, Qujing at large scale. Comparing with traditional cultivated fields, the elevation of new fields, which are red soil of moderate or low mountain slopes and gentle hills between 1 800-2 130 m, increases markedly. The agronomic traits of new cultivated fields such as plant height, stem diameter, the ground and underground biomass were better than those of traditional cultivated fields in varying degree. Furthermore, the root weight, taproot weight, taproot length and other agronomic index augmented more than 20%. Comparison among different cultivated fields showed P. notoginseng of Honghe Shiping Niujie, Kunming Shilin Guishan, Honghe Jiangshui Guanting etc. had better agronomic traits, the plant were thick and tall, the taproot and the top of reed were large, the number of root was more. Inversely, P. notoginseng of Kunming Guandu Xiaoshao, Guangxi Jingxi Lutong, Wenshang Yanshan Jiangna were thin and small. Cluster analysis showed that cultivated fields of P. notoginseng which was across clustered by traditional and new cultivated fields can be divided into three groups, including a high-yielding region insist of three new cultivated fields Honghe Shiping Niujie, Kunming Shilin Guishan, Honghe Jiangshui Guanting and one traditional cultivated field Wenshan Yanshan Jiangna. Correlation analysis indicated that the size and weight of taproot and top of reed were significantly positive correlated with plant height, stem diameter, leaf size, leaf weight and stem weight. Regression analysis pointed out that stem diameter, leaf width, leaf length/width, leaf weight were the main factors affecting the dry weight of taproot, and the main factors influencing the dry weight of top of reed were plant height, petiole, leaf length, leaf width and other agronomic traits.

CONCLUSIONFrom agronomic traits, P. notoginseng in new cultivated fields were more robust than that in traditional fields, but besides the length of taproot, the difference of rest agronomic traits didn't reach the significant level. It is suggested that, in the west and the north of traditional area, the red soil land of moderate or low mountain slopes and gentle hills where the elevation is between 1 800-2 130 m is suitable for cultivating P. notoginseng. Honghe Shiping Niujie, Honghe Jianshui Guanting, Kuming Shilin Gongshan can be used as vital development area for commodity P. notoginseng.
