Objective:To investigate the family history of congenital heart disease (CHD) in Chogqing for studying the genetic relation of CHD families. Methods:The materials were collected from the population survey about families with more than one members being CHD patients. Map pedigrees for high-risk families were made. The probands and the first and second grade relatives were asked to fill in questionnaires and the high-risk families were analyzed. Results:In the survey of 4387 families, there were 21 high-risk families in which the disease types of the relative patients were inconsistent with those of the probands, the coincidence being 33.33%(7/121).The incidence rates of the first and second grade relatives were 16.49%(16/78),1.89%(5/265) respectively and their difference was significant ( ? 2=27.73, P

Teachers'quality is an essential factor to improve teaching,and nowadays,lack of medical English teachers has become a serious problem many medical colleges have to deal with in our country. While designing the cours "eMedical English Watching,Listening and Speaking" ,English teachers,relying on their advantages of oral communication in English,can learn more basic medical theories and knowledge,and can gradually be trained as qualified medical English teachers after several years'teaching practice.

Objective To analyze the compliance of defecation function training of patients with ultra- low rectal cancer after intersphincteric resection and the influencing factors. And therefore to provide theoretical reference for the problems and nursing management of training. Methods The study was a reviewing trial. The enterostomal therapist educated patients with ultra-low rectal cancer after intersphincteric resection. Research used the basic information questionnaire, compliance evaluation of defecation function training, defecation diary and Fecal Incontinence Quality of Life Questionnaire as research instruments. And statistical analysis was used to acquired data. Results The score of the defecation function training compliance was (67.67 ± 5.28) points; Anal function and the fecal incontinence quality of life was in negative correlation with the compliance; At 9 and 12 months, anal function of patients who had good compliance were obviously improved (P < 0.05). Factors such as complications, internal sphincterotomy, operation, degree of education, pathologic stage, payment of medical expenses were related to the compliance (P < 0.05 or 0.01); The correlation analysis demonstrated that the compliance decreased with time. Conclusions The compliance of defecation function training of patients is related to anal function and the fecal incontinence quality of life. A effective training program and follow- up appointment is very important. Nurses should provide psychological counseling and health education for them to boost confidence improve quality of life.

Phosphatidylinositol 3-kinase,Akt,and the mammalian target of rapamycin (PI3K/Akt/mTOR)signaling pathway is shown to play a key role in the tumorigenesis,proliferation,metastasis,apoptosis,and angiogenesis of hepatocellular carcinoma (HCC)by regulating gene expression.The components and functions of PI3K/Akt/mTOR signaling pathway are briefly described,and the research advances in the action mechanism of PI3K/Akt/mTOR signaling pathway in the progression of HCC and related inhibitors are reviewed.It is disclosed that blocking the PI3K/Akt/mTOR signaling pathway may become a new therapy for HCC.

BACKGROUND:Maxilary posterior tooth defects can be repaired using the dental implant. However, implantation accuracy is not ensured by traditional plaster models used as implant template, which leads to the incidence of complications,andaffectsthe repair effects.
OBJECTIVE:To study application effects of surgical guide plates designed using the computer aided design (CAD)/computer aided manufacturing (CAM) technology for the repair of maxilary posterior tooth defects.
METHODS:Implant treatment was performed in 30 patients with maxilary posterior tooth defects. Surgical guide plate was made using the CAD/CAM technology after CT scan of the jaw bone. The repair was conducted with guideplateassistant. The deviation between the virtual and actual implant position was measured after implantation. The clinical repair effects and periodontal tissues were observed during the 12-month folow-up.
RESULTS AND CONCLUSION:Thirty-sixCAD/CAM surgical guide plates in 30 patients werestabilized after implantation. Thirty-six implants were emplaced precisely with the assist of the surgical guide plates. There was no any problem during the process of implantation. The deviation of the head between the virtual and actual implant position was very smal, which did not affect the accuracy of implant placement. Before and 6 and 12 months after the repair, gingival crevicular fluid, tumor necrosis factor-α, and sulcus bleeding index were not obviously changed in the patients. Our results suggest that the implant head deviation and angle deviation appearduring the repair process of maxilary posterior tooth defects using CAD/CAM surgical guide for dental implants;however, the implantation accuracy is not affected. The repair effect is ideal and periodontal tissue is in good status after implantation.

BACKGROUND:Targis/composite fiber is a new type of non-metalic repair material that has good hardness and strength, but it is rarely reported on its application in the repair of young permanent tooth defects.
OBJECTIVE:To investigate the clinical effect of Targis/composite fiber in repairing young permanent tooth defects.
METHODS:Sixty cases of young permanent teeth defects 10-17 years of age were enroled, including 27 males and 33 females. Al cases were subjected to Targis/composite fiber repairing. After 36 months of folow-up, alkaline phosphatase level, probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminotransferase level in patients were detected; the integrity and edge of dental prosthesis and the color matching.
RESULTS AND CONCLUSION:After 36 months, the alkaline phosphatase level in the patients had no significant changes (P> 0.05), but the probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminot ransferase level were decreased significantly compared with those before repair (P< 0.05). Additionaly, there were two cases of incomplete dental prosthesis, six of color mismatching, andtwo of unsealed prosthesis edge. These findings indicate that the Targis/composite fiber for repairing young permanent tooth defects has good histocom patibility maintains periodontal health in good condition, is a kind of ideal repair materials.

Objective To observe the safety and severity of heat-sensitive moxibustion in treating poisonous snakebites-induced bladder dysfunction of different degrees.Method Twenty-six patients diagnosed with bladder dysfunction due to poisonous snakebites were examined by type-B ultrasonic scanning for residual urine volume and uroflowmetry. The patients were treated with heat-sensitive moxibustion. The residual urine volume and uroflowmetry parameters were compared between different severity degrees of bladder dysfunction before and after treatment.Result The residual urine volumes were changed significantly in the mild group and moderate group after treatment (P<0.01); the residual urine volume showed insignificant change after treatment in the severe group (P>0.05). The maximum urine flow rate (Qmax) was significantly changed in the mild group after the treatment (P<0.05); the Qmax was insignificantly changed in the moderate and severe groups after treatment (P>0.05).Conclusion Heat-sensitive moxibustion is significantly effective in treating mild-moderate bladder dysfunction due to poisonous snakebites, and it’s safe and reliable.
