ABSTRACT
ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8th order（0χ-8χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUCT） of AFI and AF were （10.57±2.45）×106， （5.09±0.89）×106 μV·s， the values of total first-order moment（MCRTT） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRTT） were（24.49±2.30）， （26.49±2.54） min2， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of 0χ-8χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of 0χ-8χ MCI of flavonoids were 8.47 and 8.47， the average values of 0χ-8χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.
ABSTRACT
Objective To explore the significance of parathyroid hormone (PTH) measurement in drainage liquid after thyroid surgery,and to evaluate its relationship with parathyroid glands in situ.Methods Form Dec.2013 to Aug.2014,166 patients who underwent unilateral thyroidectomy were chosen as the research object.According to the number of parathyroid reserved in situ,patients were divided into group A0,group A1 and group A2.The levels of blood PTH and serum calcium were measured before and after operation,and postoperative PTH in drainage liquid was measured.Results The levels of postoperative blood PTH and serum calcium were lower than those before operation(P＜0.05).The difference of PTH level in drainage liquid in each group had statistical significance(P＜0.05).The level of drainage liquid PTH was highest in group A2,following group A1,and finally group A0.We found a positive correlation between the number of parathyroid glands protected in situ and the level of drainage liquid PTH.Conclusion Drainage liquid PTH measurement can be used to determine whether parathyroid gland is reserved in situ and its secretion function.
ABSTRACT
Objective To assess clinical significance of the right side lymph node dissection behind recurrent laryngeal nerve (RLN) in papillary thyroid carcinoma (PTC).Methods Clinical data of 111 cases of PTC adimitted in our hospital (Department of Vascular and Thyroid Surgery,the Union Hospital of Fujian Medical University) from Feb.2013 to Mar.2014 were retrospectively analyzed.Central lymph node metastasis was analyzed.Univariate and multivariate analysis were made to analyze relations between the right side lymph node (Ⅵ b2) metastasis behind RLN and gender,age,tumor size,capsule infiltration and so on.Results Among 111 cases of PTC,71 had central lymph node metastasis (63.96％).Total metastasis number of the right side lymph node behind recurrent laryngeal nerve (Ⅵ b2) was 2.720±2.037,and the transfer rate was 27.03％ (30/111) (P＜0.05),all lower than those of Ⅵ bl.The one-way ANOVA results showed that metastasis of the right side lymph node behind RLN (Ⅵ b2) was related with age,lateral neck dissection,and Ⅵ b1 lymph node metastasis (P＜0.05) while Ⅵ bl lymph node metastasis was the only independent risk factor for metastasis of the right side lymph node behind RLN(Ⅵ b2) in PTC.Conclusion For patients with right PTC,the metastasis rate of Ⅵ b2 is high,thus dissection of this area is favorable and can accurately reflect lymph node metastasis and further to guide tumor staging and postoperative treatment.
ABSTRACT
Objective To assess the clinical significance of reverse trendelenburg position in preventing postoperative nausea and vomiting(PONV)in thyroid surgery.Methods 110 patients with papillary thyroid carcinoma(PTC) admitted from Feb.2013 to Mar.2014 were prospectively divided into experimental group and the control group according to whether reserve trendelenburg position was adopted.Univariate and multivariate method were used to analyze relations between PONV and surgical position,gender,age,body mass index,hypertension,surgical time,ASA classification,anesthesia,and motion sickness.Results Of the 110 cases of PTC,the incidence of PONV was 16.28％ (7/43) in the experimental group while it was 37.31％ (25/67) in the control group.The difference had statistical significance(P ＜ 0.05).Statistical analysis showed that PONV was related to patients'gender,surgical position,surgical time,and motion sickness,while only surgical position and motion sickness was the independent risk factors.Conclusion Reverse trendelenburg position surgery can help to prevent PONV and promote recovery.
