ABSTRACT

Objective:To explore the association between location of lower extremity deep venous thrombosis and incidence of pulmonary embolism in patients with lower extremity fracture during hospitalization.Methods:A retrospective study was conducted of the 1,620 patients who had been treated for lower extremity fracture and deep vein thrombosis from October 2014 to November 2019 at Department of Orthopaedic Trauma, Honghui Hospital. They were 726 males and 894 females, aged from 18 to 98 years (average, 64.0 years). By the anatomical location of thrombosis, they were divided into a proximal thrombosis group and a distal thrombosis group; by the laterality of thrombosis, they were divided into a bilateral thrombosis group and a unilateral thrombosis group which was further divided into a left thrombosis subgroup and a right thrombosis subgroup. The incidences of pulmonary embolism were compared between 2 corresponding groups and subgroups.Results:Pulmonary embolism occurred in 13 of the 1,400 patients with distal thrombosis and in 12 of the 220 patients with proximal thrombosis; the incidence of pulmonary embolism in the proximal thrombosis group (5.45%, 12/220) was significantly higher than that in the distal thrombosis group (0.93%, 13/1,400) ( P<0.001). Pulmonary embolism occurred in 10 of the 337 patients with bilateral thrombosis and in 15 of the 1,283 patients with unilateral thrombosis; the incidence of pulmonary embolism in the bilateral thrombosis subgroup (2.97%, 10/337) was significantly higher than that in the unilateral thrombosis group (1.17%, 15/1,283) ( P=0.017). Pulmonary embolism occurred in 5 of the 677 patients with left thrombosis and in 10 of the 606 patients with right thrombosis; the incidence of pulmonary embolism in the right thrombosis subgroup (1.65%, 10/606) was insignificantly higher than that in the left thrombosis subgroup (0.74%, 5/677) ( P=0.129). Conclusions:In patients with lower extremity fracture, those with proximal or bilateral thrombosis are more prone to pulmonary embolism than those with distal or unilateral thrombosis, but the possibility of pulmonary embolism cannot be ignored clinically in those with distal or unilateral thrombosis.

ABSTRACT

This project aimed to explore the protective effect of ginsenoside Rg_1 on hypoxia/reoxygenation(H/R)-induced H9 c2 cardiomyocyte injury and its underlying signaling pathway. The H/R model of H9 c2 cardiomyocytes was established and then the cells were divided into different treatment groups. CCK-8(cell counting kit-8) was used to detect the activity of cardiomyocytes; Brdu assay was used to detect the proliferation of H9 c2 cells; the caspase-3 activity was tested, and then the protein expression was assessed by Western blot. Flow cytometry was used to evaluate the apoptosis level of cardiomyocytes. Ginsenoside Rg_1 inhibited H/R-induced cardiomyocyte apoptosis and caspase-3 activity, promoted nuclear transcription of nuclear factor erythroid-2 related factor 2(Nrf2), and enhanced the expression of the downstream heme oxygenase-1(HO-1). Ginsenoside Rg_1 could increase Nrf2 nuclear transcription and HO-1 expression with the increase of concentration(10, 20, 40, 60 μmol·L~(-1)). However, the protective effect of ginsenoside Rg_1 on cardiomyocytes was significantly weakened after the transfection of Nrf2-siRNA. Ginsenoside Rg_1 could protect cardiomyocytes by activating the Nrf2/HO-1 pathway.

ABSTRACT

Nonunion of femur is a common complication after intramedullary nail operation of femoral fracture, with an incidence of 1% to 12.5%. At present, the treatment of femoral nonunion is mainly divided into surgical treatment and non-operative treatment, and surgical treatment is the first choice. The gold standard for surgical treatment of femoral nonunion is replacement of intramedullary nail, but for non-isthmus femoral nonunion, larger diameter intramedullary nail could not solve the problem of rotation and angular displacement of the broken end of nonunion. For malnourished nonunion, atrophic nonunion and bone nonunion with large bone defect, the replacement of intramedullary nail and autogenous bone graft are not enough to eliminate the gap between the broken ends and increase the contact area between the broken ends. It cannot provide a good biological environment for the broken ends. Because the replacement of intramedullary nail does not expose the broken ends of bone nonunion, and the corresponding tissue cannot be taken for bacteriological culture, so it is difficult to judge whether the broken end sare complicated with infection. The double plate technique is to find the site of bone nonunion under direct vision, and two plates are placed with different angles. This paper reviews the literature related to the treatment of femoral nonunion with double plate technique published at home and abroad in the past 10 years, and concludes that double plate fixation combined with autogenous iliac bone graft provides a three-dimensional fixation model for the healing of nonunion. It has the characteristics of strong stability and plays an active role in improving the biological behavior and mechanical stability of the fracture ends. The operation is beneficial to the flexion and extension of the knee joint, with the characteristics of high healing rate, low complication rate, effective pain relief and so on.

ABSTRACT

Objective:To investigate the risk factors of deep venous thrombosis in patients before hip arthroplasty, and to explore the possible causes of postoperative thrombosis.Methods:The clinical data of 361 patients with hip arthroplasty treated in the Department of Orthopaedic Trauma of Xi′an Honghui Hospital from September 2015 to December 2019 were studied retrospectively, including 102 males and 259 females, aged 65 to 94 years, and the average age was 72.25 years old. All fracture patients were given subcutaneous injection of low molecular weight heparin calcium to prevent lower extremity thrombosis. The deep veins of both lower extremities were examined before and after operation. The general data of the two groups of patients were collected and recorded, including age, sex, whether complicated with medical diseases (essential hypertension, type 2 diabetes, coronary heart disease), serological indexes, time from injury to admission, and time from admission to operation. The software of SPSS 19.0 was used for statistical analysis.Results:The incidence of lower limb DVT, before operation was 29.92%, including 26 males (24.07%) and 82 females (75.93%). The results of multivariate logistic regression analysis showed that diabetes mellitus ( OR=2.127, 95% CI: 1.134-3.989, P=0.019), coronary heart disease ( OR=1.692, 95% CI: 1.056-2.713, P=0.029) and the time from injury to admission ( OR=1.677, 95% CI: 1.037-2.712, P=0.035) were independent risk factors for DVT in elderly patients undergoing hip arthroplasty. The incidence of lower limb DVT, after operation was 46.54%. After operation, proximal thrombus were occurred in 2 cases (1.19%), distal thrombus in 143 cases (85.12%), and mixed thrombus in 23 cases (13.69%). Postoperative thrombus was ipsilateral to the fracture limb in 84 cases (50.00%), thrombus was located in the healthy side of the fracture in 19 cases (11.31%), and DVT occurred in 65 cases (38.69%) in both lower limbs. Conclusions:Delayed admission longed than 48 hours, coronary heart disease and diabetes mellitus are the risk factors for the formation of DVT. The thrombus that existed before operation and did not disappear after operation accounted for 48.81% of the total incidence of postoperative thrombosis, and the new thrombus accounted for 51.19% of the total incidence of postoperative thrombosis. For the elderly patients with femoral neck fracture undergoing hip arthroplasty, ultrasonic examination of both lower limbs should be performed before and after operation to find the changes of thrombus in time and do a good job of prevention and treatment.

ABSTRACT

Tibial fracture is a kind of common long bone fracture of extremities, most of which are complex tibial fractures caused by high energy. Because of the special anatomical structure of tibia, the incidence of postoperative complications such as malunion and nonunion is higher. This brings some difficulties to the treatment. With the patient′s higher requirements for function, doctors have a deeper understanding of biomechanics, which promotes the further development of internal fixation materials. The indications of intramedullary nails have been expanded and gradually replaced the steel plate internal fixation for the treatment of tibial fractures and achieved good therapeutic effect. This article focuses on the application and new development of intramedullary nail in the treatment of proximal, middle, distal and open tibial fractures, providing more reference for the future clinical treatment.

ABSTRACT

Objective:To explore the incidence and risk factors of perioperative deep vein thrombosis (DVT) in patients with intertrochanteric femur fractures.Methods:A retrospective case-control study was used to analyze the clinical data of 485 patients with intertrochanteric femur fracture treated from June 2014 to September 2018 in Honghui Hospital affiliated to Xi'an Jiaotong University Medical College. There were 196 males and 289 females, aged 16 to 102 years, with an average of 74.6 years. All patients were divided into preoperative DVT group, non-DVT group, and postoperative DVT group and non-DVT group according to the results of preoperative and postoperative lower limb vein color Doppler ultrasound. The preoperative and postoperative incidence of DVT was counted and the preoperative to postoperative changes of the DVT was detected. The risk factors related to the preoperative and postoperative DVT were evaluated, including general patient information, operation time, intraoperative blood loss, intraoperative infusion volume, Surgical methods, intraoperative blood transfusion, serological indicators, etc. Single factor analysis was used to screen for risk factors, and then multivariate logistic regression analysis was used to determine the main independent risk factors.Results:The incidence of DVT before and after operation was 36.5%, 57.1%, respectively ( P<0.05). The incidence of unilateral DVT before and after operation was 30.5%, 37.1%, respectively ( P<0.05). The incidence of bilateral DVT before and after operation was 6.0%, 20.0% ( P<0.05). The preoperative rates of proximal, mixed, and distal DVT were 2.8%, 6.8% and 90.4%, respectively. The postoperative rates of proximal, mixed, and distal DVT were 2.2%, 4.7% and 93.1%, respectively. There were 293 patients (60.4%) showing no change in thrombosis, 164 patients (33.8%) aggravation, and 28 patients (5.8%) reduction. Univariate analysis showed the preoperative DVT group and non-DVT group had significant differences in gender, age, time from injury to operation, hemoglobin, hematocrit, D-dimer, previous history of venous thromboembolism (VTE), combination with injuries in other sites ( P<0.05), while not in fracture side, American Society of Anesthesiologists (ASA) score, time from injury to admission, fibrinogen, fracture AO classification, combination with medical disease, and combination with multiple medical diseases ( P>0.05). Postoperative DVT group and non-DVT group were significantly different in gender, operation method, time from injury to operation, and previous history of VTE ( P<0.05), while not in age, fracture side, operation time, intraoperative blood loss, intraoprative blood transfusion, ASA score, time from injury to admission, time from injury to operation, fracture AO classification, combination with medical disease, combination with multiple medical diseases, and combination with injuries in other sites ( P>0.05). Preoperative multivariate logistic regression analysis showed that gender, hemoglobin, hematocrit, previous history of VTE, and combination with injuries in other sites were significantly associated with preoperative DVT ( P<0.05). Postoperative multivariate logistic regression analysis showed gender, time from injury to operation and previous history of VTE were significantly associated with postoperative DVT ( P<0.05). Conclusion:The incidence of DVT is high in patients with intertrochanteric femur fractures, with a significant increase after operation. The type of thrombosis is mainly distal thrombosis and the effect of preventive anticoagulation is not satisfactory. Female, hemoglobin, hematocrit, previous history of VTE, and combination with injuries in other sites are independent risk factors for DVT before operation. Female, time from injury to operation, and previous history of VTE are independent risk factors for DVT after operation.

ABSTRACT

Objective To investigate the anatomical distribution and change of distal deep venous thrombosis in patients with hip fracture,to provide evidence for prevention and treatment of deep vein thrombosis in patients with hip fracture and lower limb deep vein ultrasound examinatio.Methods The clinical data of 383 patients with hip fractures who were admitted in Department of Orthopaedics Trauma,Xi'an Jiaotong University Medical College Red Cross Hospital from July 2014 to April 2018 were analyzed retrospectively.There were 122 males and 261 females,the age range was 17 to 94 years,the median was 78 years,and the interquartile range was 12 years.There were 154 cases of femoral neck fracture,208 cases of femoral intertrochanteric fracture,and 21 cases of femoral subtrochanteric fracture.Deep venous thrombosis was assessed by ultrasonography before and 3-5 days after operation,and the anatomical location and changes of deep vein thrombosis were analyzed.The skewed distribution data were represented by the median and interquartile range.The proportion of the number of deep venous thrombosis case in the anatomical position of the lower extremities was expressed as a percentage.Results Of the 383 patients with hip fracture who had distal deep venous thrombosis before surgery,isolated distal deep vein thrombosis (IDDVT) accounted for 89.30% (342/383),and multivessel thrombosis accounted for 10.70% (41/383).In IDDVT,intermuscular venous thrombosis was the most common,and no anterior venous thrombosis occurred.In multivessel thrombosis,two or three of the intermuscular vein,the posterior tibial vein,and the iliac vein were more common.Twenty-eight (7.31%) patients had distal thrombus extension to the proximal end (including 21 cases involving the iliac vein and 7 cases involving the superficial femoral vein),IDDVT accounted for 61.88% (237/383).The involvement of multiple venous thrombosis accounted for 16.19% (62/383),62.40% (239/383) of the distal thrombus position did not change,and 14.62% (56/383) of the distal thrombus disappeared.Conclusions For patients with hip fracture,the intermuscular vein is the most common site of distal deep venous thrombosis,ultrasound examination of anterior tibial vein is not necessary.Under anticoagulatio(n),7.31% of distal deep venous thrombosis may extend to the proximal and 14.62% of distal deep venous thrombosis disappear.For patients with hip fracture complicated with distal deep venous thrombosis in hospital,patients without contraindication of anticoagulation should be treated with anticoagulation at an early stage to prevent the proximal progression or fall off of thrombosis and reduce the risk of distal deep venous thrombosis.

ABSTRACT

Objective To investigate the occurrence of deep venous thrombosis (DVT) in the perioperative period of patients with fracture distal to the knee,so that clinicians have a better understanding of the occurrence of DVT in the perioperative period of the fracture distal to the knee.Methods A retrospective analysis of the clinical data of 365 patients with distal knee fractures who underwent surgery in the Department of Orthopaedics Trauma,Xi'an Jiaotong University Medical College Red Cross Hospital from June 2014 to March 2018 was conducted.There were 213 males and 152 females,aged (45.05 ± 15.24) years,with an age range of 17-83 years.Classification of fracture sites:177 cases of tibiofibular shaft fracture,130 cases of ankle fracture,and 58 cases of foot fracture.According to whether thrombosis occurred or not,the patients were divided into thrombotic group and non-thrombotic group before and after operation.There were 66 patients with thrombosis before operation,299 patients without thrombosis before operation,88 patients with thrombosis after operation,and 277 patients without thrombosis after operation.The incidence of thrombosis and the location of the thrombus were recorded.The sex,age,fracture site,ASA score,operation time,the time from injury to admission,the time from injury to surgery,intraoperative tourniquet time,intraoperative blood transfusion volume,intraoperative blood loss,intraoperative transfusion volume,hemoglobin volume at admission and 1 day after operation,D-dimer level at admission and 1 day after operation,multiple injuries,chronic hepatitis and medical diseases were analyzed.The measuremernt data of normal distribution and homogeneity of variance were expressed as mean ± standard deviation (Mean ± SD),the t test was used for comparison between two groups.The comparison of count data was performed by x2 test or Fisher exact probability method,and multivariate logistic regression analysis was performed on the risk factors affecting the occurrence of DVT in both lower extremities.Results The preoperative DVT rate was 18.1% (66/365).In patients with thrombosis,distal thrombosis accounted for 93.94% (62/66),and mixed thrombosis accounted for 6.06% (4/66).The incidence of postoperative DVT was 24.1% (88/365).In patients with thrombosis,distal thrombosis accounted for 94.32% (83/88),proximal thrombosis accounted for 1.14% (1/88),and mixed thrombus accounted for 4.55% (4/88).Fracture site,ASA score,operation time,intraoperative tourniquet time,intraoperative blood transfusion volume,intraoperative blood loss,intraoperative transfusion volume were not statistically significant(P >0.05).Age ≥ 40 years (OR =2.691,95% CI:1.422-5.093,P =0.002),the time from injury to admission > 3 days (OR =1.927,95 % CI:1.072-3.463,P =0.028)were independent risk factors for DVT formation in fracture distal to the knee before operation.Age ≥ 40 years (OR =3.925,95 % CI:2.161-7.129,P =0.000),the time from injury to surgery > 5 days (OR =1.835,95 % CI:1.080-3.119,P =0.025),D-dimer level at 1 day after operation (OR =1.191,95% CI:1.096-1.293,P =0.000),combined with multiple injuries (OR =1.981,95% CI:1.006-3.902,P =0.048),combined with coronary atherosclerotic heart disease (OR =2.692,95% CI:1.112-6.517,P =0.028) were independent risk factor for DVT formation after operation for fracture distal to the knee.Conclusions The occurrence of DVT before and after the fracture of the knee is mainly caused by distal thrombosis,and proximal thrombosis also occurs.Those patients aged≥40 years,combined with multiple injuries and coronary heart disease,should focus on preventing the occurrence of DVT.After the injury,the patient is immediately admitted to the hospital for DVT screening,and when the general condition allowed,shortening the preoperative waiting time can reduce the occurrence of DVT.

ABSTRACT

Objective To investigate the regularity in and risk factors for perioperative deep venous thrombosis (DVT) and the changes in plasma D-dimer in patients with tibiofibular fracture.Methods A retrospective analysis was done of the 180 patients with tibiofibular fracture who had been treated at Department of Orthopaedics and Trauma,Xi'an Honghui Hospital from September 2014 to February 2018.They were 114 males and 66 females,aged from 16 to 83 years (average,47.6 years).The levels of plasma D-dimer were detected at admission,one day preoperation,and 1,3,5 days postoperation.B-ultrasound examination of both lower extremities was performed before and after surgery.According to the results of B-ultrasound,the patients were divided into a DVT group and a non-DVT group.The 2 groups were compared in the plasma D-dimer levels measured at different time points.DVT risk factors were screened by univariate analysis,and multivariate logistic regression analysis was used to determine independent risk factors.Results Of this cohort,54 cases (30%) developed DVT and 39 cases (21.7%) did preoperation.Of the 39 cases (mixed DVT in one and distal DVT in 38 ones),DVT disappeared in 14 postoperation.Of the 40 cases (22.2%) of postoperative DVT (proximal DVT in one,mixed DVT in one and distal DVT in 38 ones),15 developed newly postoperation.Multivariate logistic regression analysis showed that age,time from injury to operation,preoperative and postoperative D-dimer elevation were independent risk factors for DVT in the patients.The D-dimer levels in the DVT group were significantly higher than in the non-DVT group at one day preoperation,and 1,3,5 days postoperation (P < 0.05).The area under the receiver operating characteristic curve was 0.704.When the critical value of D-dimer was 1.4 mg/L,its sensitivity for DVT diagnosis was 0.944 and its specificity 0.246 (poor).When the concentration of D-dimer was 4.45 mg/L,its sensitivity for DVT diagnosis was 0.574 and its specificity 0.817 (the highest).Conclusions Perioperative DVT may happen in patients with tibiofibular fracture,mostly at the distal end beyond the popliteal vein.Clinically,patients who are advanced in age,have plasma D-dimer elevation at admission and after operation,and have waited long for operation should be alert to the occurrence of DVT.The plasma D-dimer level with a recommended threshold of 4.45 mg/L may have a certain diagnostic value for patients with tibiofibular fracture.

ABSTRACT

Objective@#To investigate the regularity in and risk factors for perioperative deep venous thrombosis (DVT) and the changes in plasma D-dimer in patients with tibiofibular fracture.@*Methods@#A retrospective analysis was done of the 180 patients with tibiofibular fracture who had been treated at Department of Orthopaedics and Trauma, Xi'an Honghui Hospital from September 2014 to February 2018. They were 114 males and 66 females, aged from 16 to 83 years (average, 47.6 years). The levels of plasma D-dimer were detected at admission, one day preoperation, and 1, 3, 5 days postoperation. B-ultrasound examination of both lower extremities was performed before and after surgery. According to the results of B-ultrasound, the patients were divided into a DVT group and a non-DVT group. The 2 groups were compared in the plasma D-dimer levels measured at different time points. DVT risk factors were screened by univariate analysis, and multivariate logistic regression analysis was used to determine independent risk factors.@*Results@#Of this cohort, 54 cases (30%) developed DVT and 39 cases (21.7%) did preoperation. Of the 39 cases (mixed DVT in one and distal DVT in 38 ones), DVT disappeared in 14 postoperation. Of the 40 cases (22.2%) of postoperative DVT (proximal DVT in one, mixed DVT in one and distal DVT in 38 ones), 15 developed newly postoperation. Multivariate logistic regression analysis showed that age, time from injury to operation, pre-operative and postoperative D-dimer elevation were independent risk factors for DVT in the patients. The D-dimer levels in the DVT group were significantly higher than in the non-DVT group at one day preoperation, and 1, 3, 5 days postoperation (P<0.05). The area under the receiver operating characteristic curve was 0.704. When the critical value of D-dimer was 1.4 mg/L, its sensitivity for DVT diagnosis was 0.944 and its specificity 0.246 (poor). When the concentration of D-dimer was 4.45 mg/L, its sensitivity for DVT diagnosis was 0.574 and its specificity 0.817 (the highest).@*Conclusions@#Perioperative DVT may happen in patients with tibiofibular fracture, mostly at the distal end beyond the popliteal vein. Clinically, patients who are advanced in age, have plasma D-dimer elevation at admission and after operation, and have waited long for operation should be alert to the occurrence of DVT. The plasma D-dimer level with a recommended threshold of 4.45 mg/L may have a certain diagnostic value for patients with tibiofibular fracture.

ABSTRACT

Objective To investigate the relationship between the incidence of deep vein thrombosis (DVT) during hospitalization and the energy of injury in tibial plateau fractures (TPFs).Methods 140 patients were enrolled in the study between September,2014,and October,2017 in Honghui Hospital,Xi'an Jiaotong University.According to the Schatzker classification,the low-energy group (Schatzker Ⅰ-Ⅲ) X-ray showed a simple or lateral fracture or compression fracture of the lateral plateau (n =63);the high-energy group (Schatzker Ⅳ-Ⅵ) X-ray showed the medial tibia or double of the tibial plateau (n =77).Duplex Ultrasonography was performed in lower extremities before and after surgical intervention for DVT evaluation and record the incidence of DVT,the days during hospitalization,the blood loss during surgery and the level of D-Dimer.All patients received mechanical and chemical thromboprophylaxis.The patient was followed up for one month after surgery,and the lower extremity ultrasound was reviewed and recorded.The measurement data were expressed as ((x) ± s),and the categorical variables were expressed in composition ratio.The measurement data were all in accordance with the normal distribution and the variance was uniform.The t-test was used,and the Chi-square test was used for comparison between groups.Results The incidence of thrombosis of tibial plateau fracture in TPFs was 36.43% and 46.43% pre-operation and post-operation respectively.The thrombosis incidence was 31.75 % (20/63) in the low-energy group and 40.26% (31/77) in the high-energy group pre-operation.The thrombosis incidence was 44.44% (28/63) in the low-energy group and 48.05% (37/77) in the high-energy group post-operation.Statistical analysis showed no significant difference between the two groups pre-operation (P =0.298) and post-operation(P =0.785).The days during hospitalization [(11.94 ± 4.18) d,(9.56 ± 2.54) d],the blood loss during surgery [(208.96 ±224.43) ml,(129.68 ± 142.14) ml] and the level of D-Dimer [(2.39 ± 3.38) mg/L,(1.21 ± 2.32) mg/L] at pre-operation showed differences in the high energy group and the low energy group,respectively.Conclusions The incidence of DVT in TPFs is high during the hospital,but most of DVT is concentrated in the distal to the knee.Although the incidence of high energy injury and low energy injury DVT is not significantly different in TPFs,we should also be alert to the occurrence of DVT.

ABSTRACT

Objective To investigate the correlation between the types of constitution in TCM and the sleep status in the PLA Navy divers. Methods Eighty-nine PLA Navy divers who performed 10m diving professional training were selected. Constitution in TCM was classified and determined by the standardized standard Constitution in Chinese Medicine Questionnaire, sleep status was evaluated by the Pittsburgh Sleep Quality Index. Results 62.9% of Navy divers were the mild constitution in TCM. The eight kinds of the biased constitution in TCM are ranked with yang deficiency, phlegm-dampness, dampness-heat, qi deficiency, yin deficiency, blood stasis, qi stagnation and special intrinsic quality. Among 78 Navy divers with good sleep quality, there were 49 divers (72.1%) with the mild constitution in TCM and 19 (27.9%) with the biased constitution in TCM. Among 21 Navy divers with poor sleep quality, there were 7 divers (33.3%) with the mild constitution in TCM (accounting for) and 14 (66.7%) with the biased constitution in TCM. For Navy divers with poor sleep quality, the sleep quality scores were positive correlated with the blood stasis constitution in TCM (r=0.481,P<0.05). Conclusion Sleep status is correlated with the types of the constitution in TCM, and regulating constitution in TCM can improve sleep quality in PLA Navy divers.

ABSTRACT

Objective To measure the chromatic differences of the tongue tip and tongue side and provide quantitative evidence for tongue color diagnosis. Methods Totally 683 healthy people were recruited, and their tongue photos were taken. Then ICC specific documents were used for the correction of all tongue photos, and chromatic values (L*, a*, b*, C*and h°) of tongue tip and tongue side were obtained for further statistical analysis. CIEDE2000 was used for calculating the color differences. Results The average color difference of tongue tip and tongue side in normal pink tongue was 5.4. When pink tongue has abnormal red tongue tip, the average color difference of tongue tip and tongue side was 10.85. Compared with normal tongue tip, the average color difference of tongue tip and tongue side in abnormal color tongue with abnormal red tongue tip increased from 5.4-7.0 to 11.23. Conclusion Red tongue tip is a sensitive sign indicating abnormal heat in the body. Tongue tip quantitative diagnosis is valuable in the determination of heat sign in TCM preventive treatment of disease, and reveal the diagnosis meaning and scientific connotation of red tongue tip.

ABSTRACT

This study was aimed to discuss the diagnosis significance of the diseased tongue demonstration in Shanghuo (heatiness) people. Based on 303Shanghuo cases, the relevance of diseased tongue demonstration and inquiry data were analyzed. The results showed that 53.14%Shanghuo cases had at least more than 2Shanghuo inducing causes. The most common inducing cause combinations were pathogenic factors neither endogenous nor exogenous (unbalanced diet, overworked) and internal factors (over stressed, emotional). When there were several Shanghuo causes occurred at the same time, the probability of appearing diseased tongue demonstration increased significantly. There were 29.95%Shanghuo cases occurredShanghuo experience frequently. And in these cases, the probability of appearing diseased tongue demonstration increased significantly. It was concluded that when Shanghuo people had diseased tongue demonstration appeared, it was not merely just“is going to get ill”, but was already suffering from heat syndrome. In traditional Chinese medicine (TCM) physical examination, to effectively differentiate“is going to get ill” and“being ill” was initially important. And the diseased tongue demonstration was a crucial diagnostic basis.
