Objective To investigate the psycho-social factors related to functional gastrointestinal disorders (FGD).Methods Using Eysenck personality questionnaire (EPQ), Coping styles questionnaire (CSQ), Life events scale (LES) and Social support rating scale (SSRS) to study psycho-social factors in FGD patients. The results were compared with normal controls.Results The number of FGD patients who possessed introversion and neurosis personality was significant higher than the controls (P

Objective To develop a programmable neuromuscular electrical stimulation system as a potential countermeasure for muscle atrophy in long-term microgravity.Methods The system was mainly composed of a controllable constant current pulse generator,wires and skin electrodes.To meet the requirements of stimulating recipes selection,the stimulating parameters could be adjusted independently and the combinatorial output of different stimulating phases should also be achieved.Results The system worked well with high accuracy outputs.The sensation,contraction,tetany and pain thresholds of all the 5 waveforms stimulating signals were measured.For different stimulating waveforms,thresholds of each state were different and the subjective sensations induced by same stimulating amplitude were dissimilar.Conclusion The developed system providing powerful programmable and accurate stimulating signals,is convenient for the selection and verification of stimulating recipes and can be used as an instrument platform for study of electrical stimulation to prevent muscle atrophy in microgravity.Volunteer experiments have proved its validation for function of muscle contraction and provide primary basses for the optimization of stimulating recipes.

Objective To explore the epidemiologic al features of emergency calls around the spring festival holiday in past 5 years,so as to guide emergency medical services during holldays.Methods An investigation was made into emergency calls around the spring festival holiday in 2001～2005(1～7 of the first month of the lunar year) as well as one week before and after the holiday.Results The person-times to emergency during the spring festival holiday was correspondly stabilize in the recent 5 years,compared to the datas of the previous and subsequent 1 week,the person-times of emergency and the patients needed to rescue at first significantly increased,and the patients to pediatric emergency increased most significantly.The most part of the person-times to emergency were internal medicine.Conclusion It is essential to do a good job of health education and disease prevention,especially among high risk groups of people,and to reinforce the establishment of the emergency medical services system so as to effectively guarantee the the development of holiday economy.

AIM: To construct a human recombinant immunoglobulin library containing D-Dimer by using phage surface display technology. METHODS: Human immunoglobulin heavy chain and light chain genes were amplified respectively by RT-PCR from different human lymphocytes using family specific primers and signal sequences of immunoglobulin as half-nested PCR primers. The heavy chain and light chain PCR products were cloned into phagemid vector pComb3H and the human immunoglobulin recombination library was generated with helper phage VCSM13. RESULTS: A human combinatorial antibody library consisting of 2.8?10~8 in dependent clones was generated with a titer of 4.1?10~(17)PFU/L. The recombinant frequency of Fab genes was 46%. CONCLUSION: A human combinatorial antibody library was generated. It will be beneficial for selecting Fab antibodies of D dimer from the library.

Objective To find out about the epidemiological features of emergency calls around the National Day holiday so as to guide emergency medical services during holidays. Methods An investigation was made into e-mergency cases during the National Day holiday in 2002 (October 1-October 7) as well as one week before and after the holiday and comparison was made between the numbers of emergency cases in the past three years. Results In the past three years, the number of emergency cases around the National Day holiday has been going down year by year whereas at the same time the number of hospitalized patients and patients admitted to the observation ward has been going up. During the National Day holiday in 2002, the number of emergency cases, hospitalized patients and patients admitted to the observation ward increased markedly compared with those before and after the holiday, with the most remarkable increase in the number of pediatric emergency cases and the biggest number of emergency cases in internal medicine. Conclusion It is essential to do a good job of health education and disease prevention, especially among high risk groups of people, and to reinforce the establishment of the emergency medical service system so as to effectively guarantee the development of holiday economy.

Objective To investigate the clinical value of thromboelastography (TEG) in monitoring the coagulation function change after plasma supplementation in the patients with severe liver cirrhosis diges-tive tract hemorrhage.Methods A total of 48 patients with high risk and extreme high risk liver cirrhosis a-cute upper digestive hemorrhage receiving the treatment in ICU of this hospital from February 2020 to March 2023 were selected as the study subjects.After plasma infusion with the dose of 10 mL/kg,the coagulation function status was detected.The patients were divided into the TEG group (n=20) and the control group (n=28) according to different detection modes of coagulation function.The TEG group simultaneously detec-ted TEG and traditional coagulation function detection,while the control group only conducted the traditional coagulation detection.TEG and coagulation function detection indicators after the infusion of plasma were compared between the two groups.The plasma infusion amounts at 24 h after admitting in ICU were recorded and the control status of digestive tract hemorrhage was evaluated.Results The R value in the TEG group was (8.02±6.09)min,the K vale was 2.5(1.3,5.0)min,the coagulation comprehensive index (CI) was-4.70±6.29,the maximal shear stress coefficient (MA) was 50.35±18.84,LY30 was 0.The Pearson corre-lation analysis showed that MA was positively correlated with FIB and PLT (r=0.470,0.526,P<0.05),and the other indexes had no correlation.Compared with the control group,the plasma infusion amounts in the TEG group was more[(419.00±143.18)mL vs. (400.00±137.54)mL],the digestive tract hemorrhage con-trol rate was higher[75.00％(15/20) vs. 53.57％(15/28)],but the differences were not statistically signifi-cant (P>0.05).The multiple linear regression was MA=-3.427+11.200×Ln(PLT)+10.230×Ln(FIB).Con-clusion In the patients with severe lever cirrhosis acute upper gastrointestinal bleeding,TEG could earlier find the co-agulation function improvement situation after plasma supplementation than the traditional coagulation detection.

Objective To investigate the prevalence of metabolic syndrome(MS)and its components among people aged over 15 years in Guangxi Zhuang Autonomous Region and to compare the difference between Zhuang and Han populations.Methods Adopting cluster sampling,a survey of diabetes mellitus was conducted in Guangxi from 2003 to 2005.A total of 27 240 subjects aged over 15 years with complete data,including background information of each individual,blood pressure,lipid profile,plasma glucose,blood uric acid and fasting insulin were analyzed in this study.The prevalence of MS and its components were analysed in Han and Zhuang Chinese in Guangxi.The criteria of International Diabetes Federation(IDF)in 2005 and the China Diabetes Society(CDS)in 2004 were applied for diagnosis.Results(1)The crude prevalence rates of MS according to IDF definition were 13.15%in total,12.41%in male and 14.11%in female respectively.The age- standardized prevalence rates of MS(according to the population composition in China in 2000)were 7.66%in total,7.26%in male and 8.81%in female.The crude prevalence rates of MS according to CDS definition were 10.75%in total,13.45%in male and 7.28%in female respectively and the age-standar-dized prevalence rates of MS were 5.9%in total,7.21%in male and 4.31%in female.The prevalence of MS in total,male and female was increasing with age(P
