Chronic constipation (CC) is one of the most common digestive diseases with high prevalence and long course.CC patients often suffer from sleep disorders and psychological problems such as anxiety and depression.Somatic and mental symptoms may affect with each other, so a vicious circle will develop to impair patients′ quality of life (QOL) and increase their economic burden.The article reviews the impact of chronic constipation on QOL and economic burden of patients, indicating that clinician should pay sufficient attentions on chronic constipation.

Objective:To investigate the current status of periodontal diseases in the population at the age of 12,35~44 and 65~74 years in Chongqing,to provide information for the establishment of oral health care policies in Chongqing. Methods:A stratified equal-sized randomly sampling design was applied to obtain 751 objects aged at 12 years old,723 objects aged at 35~44 years old and 722 objects aged at 65~74 years old of three cities and three rural areas in Chongqing. The status of gingival bleeding,dental calculus,periodontal pocket and loss of attachment were assessed according to "The Guidline for the Third National Oral Health Survey" by using a CPI prode.The detection rates were calculated and were compared in aspect of area and gender. Results:In the group aged 12,the detection rates of gingival bleeding and dental calculus were 79.49% and 86.68% respectively and the detection rates of dental calculus in rural areas were higher than that of urban residents(P

Objective:To explore the significance of ethical issues in emergency medicine.Method:Literature review combined with specific features of emergency department in author's hospital is employed to explore the ethical issues in current emergency medicine,and the necessity to emphasize ethical issues.Related countermeasures are also come up with according to a small sample investigation among emergency residents in author's hospital.Result:Due to the unique characteristics of emergency medicine,there are specific ethical issues arising in emergency department.Conclusion:Enough emphasis should be attached to the reasons for ethical issues in emergency medicine.Relevant regulations and patients triage should be improved in emergency medical treatment.It is also called for to value patients' legal rights,strengthen physician-patient communication,and protect patients' life safety after emergency treatment.Meanwhile,it is also significant to relieve emergency doctors' stress at work,and strengthen sustainable on-job training and team-work of emergency doctors.

Solutions of chitosan and carrageenan were co-reacted under various experimental conditions to form water-insoluble precipitates. DR. spectroscopic studies and the counter -ions analyses revealed that the combination of the polyions proceeded through the electrostatic interaction between the - NH+3 of chitosan and the - SO3 of carrageenan, and the mole retios of N/S in the poly-electrolyte complexes (PEC) thus prepared have large scope depending on pH, the degree of deacetyla-tion (DD) of chitosan as well as the mixin ratio of the complexing components. The observation of the PEC by scanning electron microscopy showed that there exist fibrous structures in some PEC depending on such reactive conditions as pH, DD of chitosan related with the charge densities of chitosan chains. The solubility of PEC, which is greatly affected by the DD of chitosans, and the blood compatibility have also been studied.

The strain and transversal area of human anterior cruciate ligament (ACL) were investigated in 30 samples of the knee joint. The length of ACL changes with movement of the knee. The maximum strain and extension are 19.42％ and 4.65mm respectively. The mean transversal area of the ACL is 39.95?10.22mm~2. The resuults of the investigation provide morphological data for reparation and reconstruction of the ACL in clinic.

Objective To study the correlation between expression of mannose-ligand receptor(MR) on capacitated human sperm in vitro and acrosome reaction induced by zona pellucida(ZP). Methods The swimming-up sperms were incubated in capacitating medium BWW for 6 hours at 37℃, and then treated with solubilized mouse zona pellucida(mZPS).After an hour, the percentages of spermatozoa labeled with FITC-DMA were counted and used to show the expression of MR; the percentages of acrosome-reacted sperm visualized with fluoresceinated Pisum sativum agglutinin(PSA) were recorded. Results There is no correlation between expression of MR on capacitated human sperm in vitro and acrosome reaction induced by mZPS.Conclusion Expression of MR on capacitated human sperm in vitro might not be the essence of capacitation.;

Objective:To evaluate the long-term effectiveness of free transfer of Abductor hallucis muscle plus anastomosis of blood vessels and nerves for dynamic reanimation of the established facial paralysis.Methods: Twenty-eight patients who received the above-mentioned treatment during March 1999 to November 2006 were followed up.The follow-up period was 1 to 16 years,with a median period of 4 years.The facial pictures of frontal view were analyzed before and after operation.T-FGS and facial nerve function index(FNFI) were used to evaluate the facial nerve function before and after operation.Meanwhile,the survival of the graft,the width of the face,the scar,and the function of the foot were analyzed and compared.Results: All patients obtained satisfactory symmetric faces in static state and voluntary contraction of the transferred muscles.Twenty-two patients obtained ideal smiling faces.The T-FGS score increased by(27?7.2) points and the score of FNFI increased by(57?10.7)% after transplantation(P

OBJECTIVE:To establish the quality standard of New Tongzhi surunjiang capsule. METHODS:Qualitative identification of Folium Sennae,Crocus sativus and Colchicum autumnale was conducted by TLC method. The content of gallic acid in the formulation was determined by HPLC. RESULTS:The TLC spots of Folium Sennae,Crocus sativus and Colchicum autumnale were clear and well-isolated. The linear range of gallic acid was 0.155 7～1.401 3 ?g(r=0.999 8) with a mean recovery rate of 101%(RSD=1.64%,n=9).CONCLUSION:The established standard is suitable for the quality control of New Tongzhi surunjiang capsule.

Objective To optimize the processing parameters for the extraction of chlorogenic acid in Fule Granula by Box-Behnken experimental design.Methods The content of chlorogenic acid in Fule Granula was determination.The separation was performed on a Agilent ZORBAX Eclipse XDB C18 column(4.6 mm ×250 mm, 5 μm), and column temperature 30 ℃.Aetonitrile-0.2% H3PO4 was used as the mobile phase.The detection wavelength was at 327 nm.A three-factor and three-level Box-Behnken experimental design was employed to investigate effects of extraction time, solid-liquid ratio and extraction times on composite score of extracting amount of chlorogenic acid.Results Optimum process conditions were as follows:12 times the amount of water extracted three times, each time 60 min; chlorogenic acid extraction rate of 3.379%.Conclusion This optimized extraction technology has good predictability by Box-Behnken experimental design, and overall desirability, it provides a reference for application of Fule Granula.
