The prevention,diagnosis,treatment,and recovery of serious diseases can't be well done without the family's proper awareness and wisdom of choices.The target population of the prevention and control of serious diseases and health education should take a family as the basic unit and let the family become the first line of defense against the serious diseases.The idea and practice of Healthy Family has established a strong bond between the Healthy China strategy and the broad masses of the people,helping achieve the bottom-up interconnection and promoting Healthy China 2030 to benefit all.

Ethanol tolerance is related to the expression of multiple genes, and genome-based engineering approaches are much more efficient than manipulation of single genes. In this study, ultraviolet (UV) mutagenesis, dielectric barrier discharge (DBD) air plasma mutagenesis, and artificial transcription factor (ATF) technology were adopted to treat an industrial yeast strain S. cerevisiae Sc4126 to obtain mutants with improved ethanol tolerance. Mutants with high ethanol tolerance were obtained, and the ratio of positive mutants was compared. Among the three approaches, the rate of positive mutation obtained by ATF technology was 10- to 100-folds of that of the two other methods, with highest genetic stability, suggesting the ATF technology promising for rapid alteration of phenotypes of industry yeast strains for efficient ethanol fermentation.

Objective To explore the clinical features and possible carcinogenesis mechanism of the ulcerative colitis (UC)-associated colorectal cancer. Methods From 1984 to 2008, 6 clinical cases of UC-associated colorectal cancer were collected at Peking Union Medical College Hospital. The characters of morbidity, clinical features, pathology type, treatment and prognosis were analyzed.Immunohistochemistry(IHC) was performed to study the protein expression of adenomatous polyposis coli protein(APC), β-catenin, P53 and Wnt-1 in the specimens. Results The canceration of UC was 1.1 %, higher in female cases (5/6), the average duration was 14.3 years. All cases presented typical UC manifestation, most involved total colon (5/6) and none of them complicated with primary sclerosing cholangitis (PSC). There were 4 rectal cancers and 2 descending colon caners the UC cases collected. The major pathology type was adenocarcinoma with poor prognosis. The positive protein expression ratio of APC, β-catenin, P53 and Wnt-1 were 6/6, 6/6, 5/6 and 6/6 respectively.Conclusion The rectal cancer should be monitored and prevented in UC patients with total colon involved and long disease duration. Multi-pathway may possibly be involved in the carcinogenesis.

Violent trespass against medical right dangerously harms medical staffs' health,both physically and mentally.It disarranges normal infirmary system on medical diagnosis and treatment.The research carried out in 80 hospitals covering 10 provinces indicates that presently violent trespass against medical right occurs from time to time;moreover this shows an up-growing trend.Such phenomena take place in various medical colonies and medical organizations diverse themselves obviously.This passage analyzes the causes of violence from the aspects of society,hospital and physician-patient relationship.

Objective To study the rule of lower-cervical lymphatic metastasis in thoracic esophageal carcinoma,and make evaluation about the reasonable extent of lymphadenectomy. Methods One hundred and eight cases of thoracic esophageal carcinoma through chromatic ultrasound and CT before operation were divided into different groups selectively,while three fields lymphadenectomy (3-FL) was adopted in 31 cases,and two fields lymphadenctomy (2-FL) was adopted in 77 cases. Results The rate of lower-cervical lymphatic metastasis was 87.1%(27/31) through chromatic ultrasound and CT,and that was 25.0%(27/108) before the two up-mentioned examinations (P<0.05). In all cases, the rate of lower-cervical lymphatic metastasis in the upper pectoral esophageal carcinoma was 47.6% (10/21),that in the middle pectoral esophageal carcinoma was 21.3%(13161),and that in the middle and lower pectoral esophageal carcinoma was 19.5%(17187) ,P<0.05. Through 3-FL, the rate of lower--cervical lymphatic metastasis in the upper pectoral esophageal eareinoma was 57.1%(12/21), that in the middle pectoral esophageal carcinoma was 23.0%(14/61), and that in the middle and lower pectoral esophageal carcinoma was 21.8%(19/87), P<0.05. Conclusions The regionality metastasis is the main fashion in thoracic esophageal carcinoma with lower-cervical lymphatic metastasis. It is feasible to judge lower-cervical lymphatic metastasis through chromatic ultrasound and CT before operation.The 3-FL of the upper pectoral esophageal carcinoma is recommended. The 3-FL is selectable in the middle and lower pectoral esophageal carcinoma according to the result of chromatic ultrasound and CT.

Objective To study the signification of p57kip2 immunostaining to distinguish molar gestations from hydropic abortions.Methods To observe the p57kip2 immunohistochemical expression in 58 cases of histological hydropic villi which were divided into complete mole(18 cases) ,partial mole(19 cases),hydropic abortion(11 cases)and undetermined hydropic abortion or molar gestations(10 cases) and in 3 normal placentas.Results Normal villi,partial mole and hydropic abortions show positive staining for p57kip2, which expressed in the nuclei of cytotrophoblast and villous mesenchyme,and complete moles show complete absence of staining in the cytotrophoblast and villous mesenchyme.According to the comparison of the diagnosis based on morphology and the one based on p57kip2 stai-ning,the later whose sensitivity is 96% (46/48) confirmed the earlier diagnosis in 58 cases studied and the later conformed to the earlier very well.Conclusion The immunohistochemical staining for p57kip2 is a valuable diagnostic mean to distinguish molar gestations from hydropic abortions and is a sensitive and specific marker for the diagnosis of complete mole.

Objective Using MR defecography to assess the morphological and functional anorectal anomalies related to female outlet obstruction constipation, and evaluate the joint disease of anterior and mid pelvic. Methods One hundred and seven female patients, aged 20 to 84 years ( average, 55 years), were diagnosed as outlet obstruction constipation based on clinical symptoms and signs. They all received MR defecography in our institution. The high compliance homemade balloon was inserted into rectum to simulate stool Then relevant measurements were obtained during rest, squeezing and straining, respectively. Results In all the 107 cases, 70 ( 65.4% ) presented rectocele on dynamic MRI; 28 ( 26. 2% ) presented anismus;60 (56. 1% ) presented cystocele; 59 presented vaginal or cervical prolapse(55. 1% ); and, 54 (50. 5% )presented descending perineum. In 85 females (79.4%) multiple disorders were detected, involving more than one pelvic compartment. Conclusion MR defecography allowed to accurately evaluate the morphological and functional anorectal anomalies related to female outlet obstruction constipation, and the joint disease of anterior and mid pelvic.

Objective To investigate the role of renal nerve in cardioprotection provided by renal ischemic preconditioning(RIP).Methods The effects of ischemia-reperfusion and RIP on the hemodynamics, myocardial oxygen consumption, epicardial electrography and infarct size were examined in anesthetized rabbit.Results During the 45 min of myocardial ischemia and 180 min of reperfusion, all hemodynamic parameters and myocardial oxygen consumption decreased progressively significantly. Epicardial electrographic ST-segment was elevated significantly during myocardial ischemia and return to baseline progressively in the course of reperfusion. The myocardial infarct size occupied 55.80±1.25% of area at risk,and RIP significantly reduced the myocardial infarct size to 36.51±2.80%(P＜0.01). The renal nerve section (RNS) per se didn't affect myocardial infarct size produced by ischemia-reperfusion, while cardioprotection afforded by RIP was completely abolished by RNS.Conlusion RIP have the protective effect on heart, and activation of renal afferents by transient ischemia-reperfusion play an important role in such a cardioprotection.

Objective:To investigate the reasons of the tension of doctor-patient relationship and the medical violence from the perspective of the doctors, in order to provide a reference for finding a viable solution. Methods:Questionnaires survey were conducted about doctors' working conditions in 45 hospitals of 9 provinces. Results:On-ly 3. 6% medical staff had a harmonious doctor-patient relationship, the causes for the tense doctor-patient rela-tionship were poor communication with patients (75%), medical limitations (46. 2%);From the patients perspec-tive, the patients 'unpleasant caused by overtreatment due to complex illness accounted for 54. 2%;Institutional health-related reasons accounted for 82 . 6%. Conclusions:In the past five years after the new health care re-form, the tense doctor-patient relationship has not been released. So, should focus on training to enhance the com-munication skills of medical personnel and medical humanities education while the implementation of the national health care reform, in order to reduce iatrogenic conflicts.
