Objective To provide theoretical and scientific evidences for plague control,through understanding the F1 antibody level distribution and affected factor of population having healed from plague from plague natural focus of Rat.flavipectus in Yunnan Province.Methods The places and population investigated were chosen according to plague surveillant data in Yunnan Province from 1986 to 2005,using caso-control study and quesfionary. All samples were detected by indirect hemagghtination(IHA),including 248 serum samples from population having heaIed from phsue in 23 counties as case group.295 senlm samples from healthy population inoculated with EV vaccine in 7 counties as artificial immunization group, and 235 serum samples from healthy population not inoculated it in a non-plagued foei county as negative comparison group,with the diagnosing standard for positive titor being not less than 1:20.Results(①The difference WSS statistically significant(X2=44.80,P<0.05)between plague and non-plagued foci with F1 antibody positive rates being 22.10%(120/543)and 0(0/235),respectively.② The F1 antibodv positive rate of case group,35.89%(89/248)and geometric mean titer(GMT)1:84,was higher than that of artiIicial immunization group,which was 10.51%(31/295)and with GMT 1:34,respectively,the difference being statistically significant(X2=50.41,P<0.0125);the positive rate of case group wgs hisher than the neganve comparison group,the difference being statistically significant(X2=103.39,P<0.0125):the posifive mte of artificial immunization group was higher than the negative comparison group,the difference being statisticallv significant(X2=26.23,P<0.0125).③The differences were not statistically significant in the F1 antibedy positive rates of case group for age,sex,nation and occupation(X2=1.88,2.01,5.46,0.04,P>0.05).④The difference was not statistically significant in 89 plague patients with positive F1 antibody at the time of onset and rehabilitation(t= 1.23,P>0.05).Conclusions ①Plague FI antibody in people distributes the sanle a8 the plague natural focus of Rat.flavipectus does in Yunnan Province.②For naturally infected plague patients,only 1/3 popuhtion get long- term immunity,and still 2/3 can be infected again.The protecting rate and effect of naturally acquired immunity due to infection of plague are better than amfieially acquired immunity from inoculation of EV vaccine.③For the population having healed from plague,the positive rotes of FI antibody are not affected by age,sex,nation and occupation,however for those whose plague F1 antibody is still positive after some time,the titer will remain or even increase.

Renal transplantation to 37 dog was done to study relationship of the fluid imbalance with pathological changes. 1. The 9 dogs of 37 renal homografts without immunosuppressive drug survived more than 3 days. 2. In the 9 cases, BUN was elevated above the 40,K was elevated above the 7.2 mEq/L except 1 case and CI was below the normal level in 5 cases. Sodium was not changed in all cases. 3. Main direct causes of death was other than bleeding, occlusion of renal and fluid imbalance. 4. Almost all cases that showed lymphocyte and monocyte infiltation with intact glomeruli and tubule was thought to be functioning despite of histological findings of rejection. But those case that showed glomeruli and tubular necrosis was thought to be nonfunctioning because of renal ischemia. Renal necrosis and renal rejection were not related with chemical changes of the serum.

The clinic main application of medical ultrasonic techniques are introduced,including ophthalmology,neurology,angiology,cardiopathy,digestive system,urology,gynaecology and obstetrics,and surgery. Four kinds of medical ultrasonic techniques in the value on the clinic diagnosis are important,namely transcranial color -coded duplex sonography(TCCD),tissue harmonic imaging(THI),three dimensional imaging(3D),and extended field Of view(EFV).

Objective To study the effect of poly- DL- lactic acid (PDLLA) absorbable membrane on preventing adhesion after repair of peripheral nerve injury. Methods 60 SD rats were divided into 2 groups randomly: the suturing+ PDLLA group (experimental group) and the purely suturing group (contrast group), with 30 rats in each group. Their sciatic nerves were cut off and then sutured microsurgically. In the experimental group, the anastomotic stoma was encapsulated with PDLLA membrane; in the contrast group, there was no such a treatment. We conducted gross observations and histological examinations at 2, 4, 8, 12, and 16 weeks after operation, neural electrophysiological examinations at 12 and 16 weeks after operation, and image analysis by computer at 16 weeks after operation. Results The scar proliferation and adhesion near the anastomotic stoma in the experimental group were less extensive than those in the contrast group; regenerative nerve fibers grew more straight and orderly manner. Electrophysiological examinations and image analyses by computer also showed that the experimental group achieved better results than the contrast group. Conclusion Poly- DL- lactic acid (PDLLA) absorbable membrane can prevent scar proliferation and adhesion after repair of peripheral nerve and promote nerve functional recovery effectively.

Objectives To study the clinical results of Liuwei Dihuang Wan plus jinkui Shenqi Wan treating small renal calculus (diameter< 1.0cm) which are not suitable for surgical operation. Methods 200 eases were randomly recruited into a control group and a treatrnent group, with 100 cases in each group. 100 cases in the treatment group was further enrolled into team A (having the syndrome of kidney Yin deficiency) and team B (having the syndrome of kidney yang deficiency), with 50 eases in each team. Team A and team B was treated with Liuwei Dihuang Wan and Jinkui Shenqi Wan respectively. The control group was treated with drugs that removing urinary calculus. Results The cure rate and the effective rate in team A was 60% and 86% respectively; and 62% and 88% respectively in team B. The total cure rate and effective rate of the treatment was 61% and 87% respectively. On the other hand, the cure and effectively rate of the control group was 7% and 35% respectively. The difference between the two groups were significant (P<0.01). Conclusion Liuwei Dihuang Wan plus jinkui Shenqi Wan has good effect in treating small renal calculus.

Objective To explore the expression of lectin-like oxidized low-density lipoprotein receptor-1 ( LOX-1) in a rat model after balloon arterial injury and investigate the effect of cilostazol on the mRNA and protein expressions of LOX-1. Methods Twenty-four male SPF SD rats were randomly divided into 3 groups ( n =8 for each group) ,sham operation group,balloon arterial injury group and cilostazol treatment group. For the rats from balloon arterial injury group and cilostazol treatment group,the left common carotid artery were in- juried by a balloon catheter. The expression of LOX-1 mRNA and protein in neointimal hyperplasia after balloon arterial injury were examined by RT-PCR and immunohistochemistry respectively. The contents of MDA in blood serum was examined by TBA. Results LOX-1 mRNA and protein were expressed in the neointimal hyperplasia after balloon arterial injury but not in the sham-operation group. The expression level of LOX-1 was significantly lower in the cilostazol treatment group than that in the model group ( P

AIM To compare the new methods which can be used fo r soring the stages of rat sleep. METHODS Cortical EEG and hippocampal potential(HP) were collected by implanted electrodes in freely moving rats. Gravity frequency (f g) and the complexities(Kc,C 1), were calculated. According to the characteristics of each stage and by studying the histogram of f g, Kc and C 1, the stages of rat sleep were distinguished. RESULTS The methods of f g, Kc and C 1 can distinguish the Waking, nonrapid eye movement(NREM) and REM sleep well. Comparing the results of visual and our analysis, the rate of accordance is above 85%, and the analysis based on the complexity measure is more believable than that based on the f g. CONCLUSION The gravity frequency and the complexities of Kc,C 1 can be used to distinguish the different stages of rat sleep.

365 low birth weight infants have been born inour Obstetric Department in the past two years. Aretrospective investigation of their morthers' con-ditions during pregnancy and delivery which had aneffect on their babies weight was done. The resultsshowed that incidence of low birth weight infantswas 7. 99% and mortality rate was 15. 07%. The care.X~2 test indicated that hypertention syndrome ofpregnancy and anemia which the mothers sufferedfrom were the main diseases which affected birthweight of infants. The analysis of multiple stepwiseregression showed that the most dangerous factorswere peasant mothers, premature and neonate ab-normity. So we must strengthen perinatal healthcare.
