Uncertain Impact Statements Syndrome Objective Indicators Of Clinical Research

Clinical study of objective quota in diagnosis of unidentified clinical syndrome Postgraduate:Sang Qingwen Tutor:hn Xlangmo Objective To Investigate tile objective quota In diagnosis of unldenttfled clinical syndrome(UCS),to clarify its exal。lining methods and diagnostic value．Methods 50 patients wltll UCS were selected and divided Into two groups according to their sequence ofconsulting a doctor,the former 25 patients were unldentlhed clinical syndrome groupl(UCSI),the latter25 patients were unldentlhed clinical syndrome group 11(UCSll)．25 healthyhuman beings were normal control group(CON)．There was no difference In sex and age among three groups(P＞0．05)．The autonomic nervous function of Datl＊ms lfl乙hi WeTe eX＊mllleQ Wltll CV卜＊e3了t TC二leX ．test(EHRT),skin－scratching test(SST)and the orthostatlc test(TOT)．The autonomic nervous function ofpatlents In UCS 11 were examined with hand－gripping test(HGT), deCp－bf～8thlllg tCSt(DBT),lylllg－to－Stslldlllg t6St(LST), Valsalva maneuvering test(VMT)and whether the symptom＠lofcoldexlstedwasdlagnosedwlthShellong'slying－to－ ,3standing test(SLST). The healthy human beings in CON weredone with all the above tests. Results The patients with UCS?had autonomic nervous dysfunction, they had sympathetichyperfunction and relativeparasympathetic hypofunc-tion.The heart rate(HR) of UCS I was higher than that ofCON after pressing in EHRT(P<0.O1).The positive rate ofwhite line of UCS I was higher than that of CON (P<0.05)while the positive rate of red line was no difference betweenUCS I and CON(P>0.05) in SSRT. The longest R-R intervalwas significant difference(P<0.05), the shortest R-R intervalwas no difference(P>0.05) between UCS II and CON, theratio of UCS IL was lower than that of CON(P<0.05) in DBT.The 30th R-R interval was significant difference(P<0.05),the 15th R-R interval was no difference(P>0.05) betweenUCS H and CON, the 30/1 5 ratio of?UCS II was lower thanthat of CON(P0.05) between UCS II and CON, theValsalva ratio(VR) of UCS II was lower than that ofCON(P<0.05) in VMT. The systolic BP(SBP), strokevolume(SV), cardiac index(CI) and SVR were significantdifference(P<0.05) while the diastole BP(DBP) and HR were慡ino difference(P>0.05) after standing between UCS II and 4CON, showing the symptom of cold existed SBP and DBPduring TOT and HGT respectively were no differencebetween two groups (P>O.05). Conclusion The clinicalsymptoms of UCS were brought about by autonomic nervousdysfunction, especially, sympathetic hyperfunction. Theexamining methods of autonomic nervous system could giveits diagnosis.
