ABSTRACT
Objective To observe the change of serum smooth muscle myosin heavy chain (smMHC) level in the patients with aortic dissection (AD),and evaluate the effect of smMHC in the early diagnosis and prognosis of AD.Methods Forty-two patients with AD were selected as AD group,30 healthy subjects were selected as control group.Blood samples were collected at four time periods (within 3 h of onset,6 h,12 h,24 h),and serum smMHC level were measured by enzyme-linked immunosorbent assay.Results Serum smMHC level of AD group,which collected (within 3 h of onset,6 h,12 h) were significantly higher than that of control group [(88.6 ±21.7),(59.4 ± 18.7),(41.3 ± 10.7) ng/L vs.(17.2 ± 8.3) ng/L,P ＜ 0.01].There was no significant difference between the serum smMHC level of AD group and control group at 24 h after onset [(18.9 ±9.5) ng/L vs.(17.2 ±8.3) ng/L,P ＞ 0.05].Serum smMHC level of Stanford A type group (25 cases) was higher than that of Stanford B type group (17 cases) within 3 h of onset [(95.4 ± 17.8) ng/L vs.(78.5 ± 18.3) ng/L,P＜0.01],and there was no significant difference bewteen the two groups which collected at 6,12 h and 24 h after onset (P ＞ 0.05).Preoperative serum smMHC level was significantly higher than that after intracavitary isolation operation [(58.6 ± 15.9) ng/L vs.(30.1 ± 12.5) ng/L,P ＜ 0.01].Serum smMHC level decreased rapidly after the operation,and there was no significant difference between the two grougs when 12 h after operation [(18.7 ± 8.9) ng/L vs.(17.2 ± 8.3) ng/L,P ＞ 0.05].The serum smMHC level of the deaths (7 cases),which collected within 3 h of onset,6 h,12 h,was significantly higher than that of the survivors (35 cases) [(101.2 ± 20.7) ng/L vs.(86.1 ± 18.9) ng/L,(65.2 ± 16.7) ng/L vs.(58.2 ± 14.2) ng/L,(50.4 ± 10.8) ng/L vs.(39.5 ± 8.3) ng/L,P ＜ 0.05],and there was no significant difference at 24 h after onset (P ＞ 0.05).Detecting serum smMHC level within 3 h of onset,the area under the receiver operating characteristic curve was 0.913,with 51.7 ng/L as a diagnostic critical value,sensitivity and specificity respectively was 88.1％ (37/42) and 96.7％ (29/30).When detecting at 6 h after onset,the area under the curve was 0.865,with 38.5 ng/L as a diagnostic critical value,sensitivity and specificity respectively was 90.4％(38/42) and 90.0％ (27/30).Conclusions The level of serum smMHC in patients with AD increase rapidly after onset,and detecting serum smMHC level within 6 h of onset have important clinical significance in early diagnosis and prognosis of AD.
ABSTRACT
Objective To observe the traditional Chinese medicine (TCM) and umbilical treatment on diarrhea-predominant irritable bowel syndrome(IBS-D)with mental disorders. Methods Thirty-seven cases with IBS-D were randomized into a treatment group(33 cases) and a control group(31 cases). The treatment group was given Shugan-Jianpi TCM decoction and pepper umbilical dressing. The control group was given Pinaverium Bromide Tablets and Flupentixol and Melitracen tablets. After having been treated for 4 weeks, Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), IBS Symptom Severity Scale(IBS-SSS), IBS quality of life questionnaire (IBS-QOL) were determined. Results After the treatment, HAMD, HAMA, IBS-SSS in the treatment group and the control group all significantly decreased (the treatment group t=14.280, 13.530, 18.847,the control group t=11.514, 9.424, 13.829, P<0.01), and IBS-QOL increased markedly(t=-16.848, -11.712, P<0.01). Compared with HAMA, IBS-SSS and IBS-QOL in treatment group, the control group showed statistical difference(t=-3.183, -2.549, 3.904, P<0.01 or 0.05). The total effective rate of the treatment group was 94%higher than 75%of the control group(χ2=4.727, P<0.05). Conclusion Shugan-Jianpi TCM decoction and pepper umbilical dressing can improve the clinical symptoms and psychological symptoms and improve the quality of life of IBS-D patients.
ABSTRACT
Objective To investigate the TCM constitution and living habit of inhabitant of Guangzhou nansha.Methods 500 inhabitants of Guangzhou nansha in our hospital were determined by questionnaire,including TCM Constitution,eating habit,sleeping habit and exercise habit.Results There were 26 cases of harmonious constitution(5.2％),474 cases of partial constitution(94.8％).Among the partial constitution,there were 211 cases of single-side constitution (42.2％),the frequency order from high to low was Qi deficiency constitution (12.8％),dampness heat constitution (8％),yang deficiency constitution (6.2％); 179 cases of two-side constitution(35.8％),the sequence was qi deficiency with phlem-dampness constitution (6.2％),Qi deficiency with dampness heat constitution (4.2％),Qi deficiency with Yin deficiency constitution (3.8％).Eating habit (x2=22.449),sleeping habit (x2=17.726) and exercise habit (x2=16.207) had significant dependablity with partial constitution (P＜0.01).Conclusion The main TCM constitution of inhabitant of Guangzhou nansha was Qi deficiency constitution,dampness-heat constitution,Yang deficiency constitution,phlegm-dampness constitution.Partial constitution was closely related with living habit.
