Objective To study the effect of fluorine on the bone histomorphometry of humbar in rats.Methods Ninety 2-month-old SPF Sparague-Dawley rats,half male and female,were randomly divided into 9 groups:control[(childhood(CS),adult(AS),long-time(NS)]group and drug group[childhood high-fluoride and low-fluoride group(CHS,CLS),adult high-fluoride and low-fluoride(AHS,ALS),long-term high-fluoride and low-fluoride(CLHS,CLLS)].The control group was administered orally with solution of 0.9%NaCl,while the drug group was given orally with different dose of NaF at the same time. Sections of the fifth lumbar were made which was undecalicified for bone histomorphometric analysis, including the percentage of trabecular bone area (% Tb.Ar),trabecular thickness(Tb.Th), trabecular number(Tb.N), trabecular separation(Th.Sp) ; broken trabecular bone area cells (Oc.N), osteoclast perimeter percentage (% Oc.Pm), the percentage of labeled perimeter (% L.Pm), bone mineral apposition rate(MAR), osteoblast perimeter(Ob.PM), trabecular bone perimeter formation rate (BFR/BS),trabecular bone area formation rate (BFR/BV), the total area of bone formation rate (BFR/TV). Results [1]The percentage of Tb.Ar, Tb.Th, Tb.N,%L.Pm, MAR, BFR/BS, BFR/BV and BFR/TV of CHS group [(50.63 ±7.44)%, (150.26 ± 27.51 )μm, (3.44 ± 0.47)N/mm, (50.63 ± 7.44)%, (0.85 ± 0.03)μm/d, (8.45 ± 2.36)μm/d ×100, (381.16 ± 41.62)%/year, (75.07 ± 4.81)%/year] was higher than that of CS group [(29.71 + 9.32)%,(110.93 ± 28.19)μm, (2.68 ± 0.34)N/mm, (24.00 ± 1.22)%, (0.65 ± 0.03)μm/d, (5.43 ± 0.18)μm/d × 100,(141.32 ± 9.29)%/year, (58.14 ± 2.3)%/year, all P < 0.05)]. The %Tb.Ar, Tb.Th, %L.Pm, MAR, BFR/BS,BFR/BV, BFR/TV and Ob.PM of CLS group [(40.76 ± 6.43)%, (164.25 ± 45.65)μm, (42.02 ± 6.12)%, (0.85 ±0.04)μm/d, (8.95 ± 3.73)μm/d × 100, (378.73 ± 35.39)%/year, (73.52 ± 8.71)%/year, (1.41 ± 0.05)μm] were increased (all P < 0.05). [2]Compared with AS group, the %Tb.Ar,Oc.N, %Oc.Pm, %L.Pm, MAR, BFR/BS,BFR/BV and BFR/TV of AHS group[ (50.62 ± 5.76)%, (0.51 ± 0.05)N/mm, (1.13 ± 0.05)%, (42.3 ± 7.02)%,(1.28 ± 0.09)μm/d, (12.91 ± 1.52)μm/d × 100, (390.12 ± 43.56)%/year, (65.21 ± 22.13)%/year] was higher than that of AS group[ (42.73 ± 5.22)%, (0.41 ± 0.17)N/ram, (0.77 ± 0.52)%, (28.43 ± 6.93)%, (0.80 ± 0.03)μm/d, (9.83 ± 1.44)μm/d × 100, (324.43±53.44)%/year and(48.35 ± 9.36)%/year, all P < 0.05)] . The %Tb.At, Oc.N, %Oc.Pm, %L.Pm, MAR, BFR/BS, BFR/BV and BFR/TV of ALS group [(51.14 ± 6.22)%, (0.49 ±0.61)N/mm, (1.17 ± 0.11)%, (45.06 ± 6.92)%, (1.39 ± 0.08)μm/d, (12.87 ± 1.35)μm/d × 100, (394.6 ±50.23)%/year and(66.31 ± 18.93)%/year] were higher than that of AS group(P < 0.05) .[3] The Ob.PM ,Oc.N and %Oc.Pm of CLHS group[ (1.47 ± 0.27)μm, (0.58 ± 0.13)N/mm, (1.14 ± 0.07)%] were obviously increased(P <0.05), as compared with NS group [ (0.82 ± 1.20)μm, (0.42 ± 0.25)N/mm and (0.75 ± 0.64)%, all P < 0.05].Conclusions The short-term administration of NaF on rats in the growing period increases the bone formation and osteoblast activities of young rats and adult rats. The long-term administration of NaF on rats does not increase the bone formation of rats in growth period. The osteoblast activities as well as the bone absorption of lumbar vertebra were strengthened. The likelihood of bone fracture became larger. The negative effects on bone metabolism and bone quality of rats were gradually displayed along with the prolongation of sodium fluoride usage.

Objective To explore the nursing intervention on the pregnant women with syphilis during pregnancy so as to reduce the harm to maternal and baby.Methods Many information such as age,occupation,dwelling environment,marriage and sexual life,curing during pregnancy,pregnant and perinatal infant outcome from medical records were reviewed. Gestational syphilis women of 847 cases were randomly divided into nursing intervention group with 427 cases and control group with 420 cases.Nursing intervention group received one-by-one psychological care and health education,got cooperation from families,and received routine blood test and cure cooperation,while control group only received routine blood test and curing cooperation.Patients were followed up for seven days.Results The rate of adherence to treatment in nursing intervention group was 98.1％ which was significantly higher than 61.7％ in control group ( x2 =176.2,P ＜ 0.01 ),and the rate of accepting standard treatment between early and late pregnancy,middle and late pregnancy were significantly higher than that in control group ( x2 =17.8,P ＜ 0.01 ).The week was shorter for receiving nursing intervention and the patients' compliance was better ( P ＜ 0.01 ). Only 23 syphilis infection babies in the nursing intervention group were born,but 149 babies in control group were infected by syphilis,and the difference was significantly different( x2 =123.2,P ＜ 0.01 ).Conclusions Nursing intervention can effectively increase the compliance of pregnant women with syphilis and improve the outcome of pregnancy and perinatal infant.

OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).

METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.

RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.

CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

An antibiotic-producing bacterium, which was numbered as 20 #-5, was separated from the soil in Chongqing. It was identified as the member of pseudomonas. Gram positive bacteria are badly suppressed by it. The antibiotic secreted by 20 #-5 can endure 100℃ for half an hour, and it can also go through the ultrafiltration membrane with pores of 0.22?m.

Objective To explore the value of electrocardiogram in predicting culprit vessels in acute inferior myocardial infarction.Methods The clinical data of 129 patients with acute inferior myocardial infarction admitted to First Affiliated Hospital of Army Medical University from January 2015 to December 2021 were retrospectively analyzed.Patients were received coronary intervention treatment,and the culprit vessels were identified by coronary angiography.The culprit vessels during surgery were recorded.The preoperative electrocardio-gram of patients were analyzed,a new method for predicting culprit vessels in acute inferior myocardial infarction was established based on the previous researches,and the accuracies of the Fiol method,Tiala method,Huang's algorithm and new method in predicting the culprit vessels in acute inferior myocardial infarction were also counted.The predictive abilities of various methods on culprit vessels were evaluated using receiver operating characteristic(ROC)curve and the area under the curve(AUC)was calculated.Results The culprit vessels of 109 patients were the right coronary artery,16 cases were the left circumflex artery,and 4 cases were the anterior descending artery.A total of 52 patients developed clinical complications,of which the culprit vessels of 47 cases were right coronary artery and 5 cases were circumflex artery.The accuracies of the Fiol method,Tierala method,Huang's algorithm,and new method in predicting culprit vessels were 83.7%,81.4%,82.9%,and 85.3%,respectively.The ROC curve analysis showed that the Fiol method(AUC=0.941),Tierrala method(AUC= 0.945),Huang's algorithm(AUC=0.945),and new method(AUC=0.964)all had strong predictive ability for culprit vessels.Conclusion For patients with acute inferior myocardial infarction,the Fiol method,Tierala method,Huang's algorithm,and new method all have high predictive value for culprit vessels in analyzing the preoperative electrocardiogram,and the new method has a higher predictive value.

OBJECTIVETo explore the prevalence of syphilis and risk factors on pregnant women in Fujian province.

METHODSFrom July 1st, 2004 to June 30th, 2006, epidemiologic methods as questionnaires to fill in and rapid plasma reagent testing (RPR) were performed. Pregnant women with positive RPR test and then were confirmed by treponema pallidum test (TP). Intervention was provided to the pregnant women who were followed up to the postpartum periods. Results were compared during the peri-neonatal stage between syphilis-infected and non-infected women. Factors which were relative to syphilis infection were analyzed by simple and then further logistic regression analysis.

RESULTSThere were 38 418 pregnant women under study, of whom 772 were confirmed including 60 who were still pregnant. The prevalence of syphilis during pregnancy was 1.85% (712/38 418), with mostly underlying syphilis which played an important role during the neonatal stage. Main risk factors to have been found as: women's occupation, cultural background, place of living, husband's occupation, family income, having sexually transmitted disease(STD) infection. The prognosis of peri-neonatal stage was worse if the mother was having blood RPR test positive. Mortality of peri-neonatal, preterm birth rate and low-birth weight rate were found also higher among mothers when RPR was positive (P < 0.01).

CONCLUSIONThe prevalence of syphilis in Fujian province was going up yearly. 8 factors including women's occupation, cultural background, place of living, received poor health education, having multiple sexual partners, husband's occupation, family income and having STD were main risk factors in the province, the mother's status of syphilis infection would strongly relate to the peri-neonatal stage of pregnancy.
