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.

Objective To observe the clinical efficacy of abdominal acupuncture plus herbal medicine in treating chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases.Method Sixty patients with chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by abdominal acupuncture plus herbal medicine, while the control group was by herbal medicine alone. After 3 menstrual cycles, the Visual Analogue Scale (VAS) for abdominal pain and McCormack scale were observed.Result After intervention, the abdominal VAS score and McCormack score were changed significantly in both groups (P<0.01,P<0.05). After intervention, there were significant differences in comparing the VAS score and McCormack score between the two groups (P<0.01).Conclusion Abdominal acupuncture plus herbal medicine can reduce chronic pelvic pain due to qi stagnation and blood stasis after pelvic inflammatory diseases.

Objective To explore whether antibiotic prophylaxis is beneficial in tension-free in-guinal hernia repair Method A perspectiverandomized controlled study was conducted which included 1 28 patients who underwent tension-free inguinal hernia repair from July 201 1 to August 201 3.In the anti-biotic prophylaxis group,antibiotic was intravenously administrated within 30 minutes before surgery.In the control group,no preoperative antibiotic wasadministrated.The incidence of incision infection was com-pared between groups.Result Incision infectiondeveloped in onepatient of the antibiotic prophylaxis group and two patientsin the placebo group,indicating no significant difference between the groups(P >0.05).Conclusion Before tension-free repair,there is no real need to apply prophylactic antibiotics reg-ularlyfor inguinal hernia without high risk factors.

One hundred kinds of excellent books on basic medicine were selected from Wanfang Data Knowledge Platform to develop a books-papers citation database.Their academic levels of the selected books were evaluated by PageRank algorithm.The chapters and sections of the books were divided into 4 parts according to their PageRank value and the distribution characteristics of their citation frequencies to study the PageRank and the top 20 cited chapters and sections of the books.The advantages and disadvantages of PageRank algorithm in book evaluation were described.

Clinical obstetrics practice is a very important process. According to our exploration on it on 7-year-systemmedical students in our hospital for nine years, we think that if you want high quality 7-year-system medical students,five concepts should be emphasized besides traditional basic knowledge, basic theory and basic skill, which are familyplanning and eugenics, loving infants, whole concept, new medical model and renewing knowledge.

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.

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
