【Objective】 To sequence P1 gene(184～1946 bp) includ ing SBR gene in expressional plasmid of transgenic plant. 【Methods】 pROP1 plas mid was extracted from E. coli DH5α, P1 gene was sequenced by PCR sequence kit and DNA autosequencer and compared with surface protein gene of Streptococc us mutans in GenBank. 【Results】 616 base pairs from 5′ end and 466 base pairs from 3′ end were sequenced, its accuracy is up to 98%. 【Conclusion】 The seq uence of P1 gene's 5′ end and 3′ end is consistent with DNA sequence of SBR re gion of Streptococcus mutans surface protein pac gene and may provide useful in formations to construct the transgenic plant anticaries vaccine.

Objective To analyze the clinical characteristic of disseminated intravascular coagulation(DIC)complicated by placental abruption,improving the diagnosis and treatment level.Methods A retrospective analysis of clinical data of placental abruption complicated by DIC was made in 28 cases.Results In 28 cases,hypertensive disorders in pregnancy( n =15) was the main cause,persistent abdominal pain and vaginal bleeding was the most common complaint.There were 6 cases delivery through vaginal,and 22 cases delivery by cesarean section,complicated by hemorrhagic shock in 9 cases,accounting for 32.1％,concurrent stillbirth in 20 cases,accounting for 71.4％.In 28cases,there were live births in 8 cases,after childbirth and newborn severe asphyxia in 6 cases,including 2 cases after the rescue of neonatal death,and another 4 patients after the rescue of neonatal survival.The occurrence of uterine subtotal or total hysterectomy was in 6 cases,accounting for 21.4％,acute renal failure in 2 cases,no maternal death.Conclusions Placental abruption complicated with DIC made a serious threat to maternal and child life and health,and the pregnancy should be terminated immediately after clinical diagnosis.DIC was not a hysterectomy indications,coagulation factors can help to correct the coagulation disorders,and to preserve the uterus and maintain the maternal physical and mental health.

Objective:To observe the therapeutic efficacy of acupuncture plus heat-sensitive moxibustion in treating chronic pelvic inflammatory disease (CPID), for selecting an effective acupuncture-moxibustion method in treating chronic pelvic inflammation. Methods:Eighty CPID subjects were enrolled and divided into two groups by randomized single-blind method, 40 in each group. The observation group was intervened by acupuncture plus heat-sensitive moxibustion, while the control group was by acupuncture plus box-moxibustion, once every other day, 10 sessions as a treatment course, but the period time was skipped. The therapeutic efficacy was observed after 3 treatment courses. Results:The recovery rate was 45.0% and the total effective rate was 95.0% in the observation group, versus 20.0% and 80.0% in the control roup. There were significant differences in comparing the recovery rate and the total effective rate between the two groups (P<0.05). Conclusion:Acupuncture plus heat-sensitive moxibustion can produce a higher therapeutic efficacy in treating CPID than acupuncture plus box-moxibustion, and this is an easy-to-operate and safe method without adverse effect.

Objective To study the correlation between the expression of activator protein-1 (c-Fos/c-Jun) mRNA and gingival inflammation,so as to discuss the pathogenesis of periodontitis.Methods The gingival tissues were divided into three groups according to the gingival index (GI),including GI=0 group (control group,14 cases),GI=1 group (15 cases) and GI=2 group (11 cases).The total RNA in each gingival tissue was extracted,and cDNA was synthesized by reverse transcription synthesis.The expressions of c-Fos and c-Jun mRNA in healthy gingival tissue (GI=0 group) were detected by reverse transcription-polymerase chain reaction.The levels of c-Fos and c-Jun mRNA in all the groups were detected by real-time quantitative PCR.Results Both c-Fos and c-Jun mRNA was expressed in healthy gingival tissues.The levels of c-Fos and c-Jun mRNA in GI=1 group was 15.58±9.19 and 3.47± 1.77,respectively,which was significantly higher than 1.31±1.03 and 1.32±0.94 in GI=0 group,and the differences were statistically significant (all P＜0.05).The level of c-Fos mRNA in GI=2 group was 3.01±1.48,which was lower than that in GI=1 group (P＜0.05) and higher than that in GI=0 group (P＜0.05).The level of c-Jun mRNA in GI=2 group was 1.48±0.65,which was lower than that in GI=1 group,and had no significant difference with GI=0 group (P＞ 0.05).Conclusions Activator protein-1 (c-Fos/c-Jun) is associated with the degree of gingival inflammation,suggesting that it is involved in the occurrence and development of gingival inflammation.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.
