OBJECTIVETo study the correlation between various complications of chronic heart failure (CHF) patients and Chinese medical syndromes, thus indicating distribution laws of Chinese medical syndromes in various complications of CHF patients.

METHODSChinese medical syndrome typing was performed in 630 CHF patients by cross-sectional study of the demographic data, history of present diseases, related information on Chinese medical four diagnostic methods, and the distribution of complications. Logistic regression analysis was used to determine the correlation of various complications of CHF patients and Chinese medical syndromes.

RESULTSIn this study, recruited were common complications such as hypertension, diabetes, arrhythmia, hyperlipemia, and cerebral vascular accident, and so on. Main syndromes were sequenced as qi deficiency syndrome, blood stasis syndrome, water retention syndrome, yin deficiency syndrome, phlegm turbid syndrome, yang deficiency syndrome. Results of Logistic regression analysis indicated that correlation existed between common complications and Chinese medical syndromes. In CHF complicated hypertension patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with hypertension (P < 0.05). In CHF complicated diabetes patients, Logistic regression analysis showed phlegm turbid syndrome and water retention syndrome were positively correlated with diabetes (P < 0.05). In CHF complicated arrhythmia patients, there was no statistical difference in the distribution of each syndrome (P > 0.05). In CHF complicated hyperlipemia patients, Logistic regression analysis showed qi deficiency syndrome and water retention syndrome were negatively correlated with hyperlipemia (P < 0.05), while blood stasis syndrome, yin deficiency syndrome, and phlegm turbid syndrome were positively correlated with hyperlipemia (P < 0.01). In CHF complicated cerebral vascular accident patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with cerebral vascular accident (P < 0.01, P < 0.05).

CONCLUSIONSThere existed certain correlations between complications of CHF and the distribution of main Chinese medical syndromes. It could be used as guidance for treating CHF and its various complications by Chinese medicine and pharmacy.

Objective To evaluate the value of blood coagulation biomarkers in orthopaedic traumatic patients after surgery and analyze its diagnostic values for venous thrombosis embolism.Methods In thiscase control study, we consecutive enrolled 108 traumatic patients after surgery.54 patients have thrombosis and other 54 patients have no thrombosis.Blood was taken 3 -4 days after surgery.Routine coagulation screening test , FDP(fibrinogen/fibrin degradation products) , D dimer and new item such as TM( thrombomodulin) , TAT( thrombin-anti-thrombin complex) , t-PAIC( tissue-type plasminogen activator-plasminogen activator inhibitor complex),PIC(plasmin-anti-plasmin complex) were tested.The difference between groups of these biomarkers was compared, and then the receiver operation curve ( ROC) was drew to determine the diagnostic cut-off point and diagnostic performance.Results ALL blood coagulation biomarkers in orthopaedic traumatic patients after surgery were significantly increased.The group of patients with thrombosis have higher TM(9.04 ±2.06) IU/ml,t-PAIC(10.15 ±4.23) ng/ml, PIC(1.15 ±0.70)μg/ml, D dimer(5.31 ±5.10) ng/ml than group without thrombosis TM(7.50 ±1.70) IU/ml, t-PAIC (6.97 ±2.56)ng/ml, PIC(0.93 ±0.84)μg/ml,D dimer(2.35 ±2.12)ng/ml,and P=0.000 2,<0.000 1,<0.000 1,<0.000 1, respectively.However, TAT(4.79 ±4.32)ng/ml, (6.51 ±5.92)ng/ml, FDP (8.87 ±7.68 )μg/ml, ( 4.91 ±4.67 )μg/ml showed no difference between thrombosis groupand no thrombosis group, (P=0.212 3,0.050 8; respectively).The area under the ROC curve of TM, t-PAIC, PIC and D-dimer were 0.718 5,0.741 6,0.648 0,0.670 0, respectively; P values were <0.000 1,<0.000 1, 0.009 3,0.004 1, respectively; cut-off values were 11.15 IU/ml, 10.65 ng/ml, 1.36 μg/ml, 7.69 ng/ml, respectively;positive likelihood ratios were 9.00,11.29,3.66,14.60, respectively;specificity were 98.15%,96.23%, 90.20%, 97.96%, respectively; the diagnostic rates were 20.3%, 46.3%, 35.8%, 25.9%, respectively.Conclusions There were coagulation and fibrinolysis system activated in orthopaedic traumatic patients after surgery.TM, t-PAIC, PIC, D dimer were good biomarkers for the diagnosis of thrombosis after trauma surgery.TAT was not fit for screening thrombosis after surgery because of influence of anti-coagulation.

Objective To construct four types of glucagon-like peptide-1 (GLP-1) and human serum albumin (HSA) fusion proteins that can be realeased at different rate in vivo by introducing protease cleavage sites between these two moieties.The therapeutic effect and release rate are studied to achieve balanced pharmacokinetics ( PK) and pharmacody-namics ( PD) of GLP-1 and HSA fusion proteins.Methods The gene with different polypeptide joint of GLP-1 and HSA fusion proteins were synthesized by overlap extension PCR amplification, cloned into expression vector pPIC9 and transformed into Pichia pastoris GS115.Then, fusion proteins were obtained by protein purification after being induced by methanol.The preliminary PK and PD of the fusion proteins were studied after purification.Results The fusion protein Gly2-GLP-1-GGGGG-HSA showed no release while Gly2-GLP-1-VTR-HSA, Gly2-GLP-1-SARSVRA-HSA, and Gly2-GLP-1-GRSRVTRSV-HSA showed a slow, medium and fast release rate, respectively, after incubation with furin.In vitro biological activity test results dispalyed that each type of fusion protein promoted insulin secretion of MIN6 cells.In vivo PK test indicated the half-life size of fusion proteins was the largest in Gly2-GLP-1-GGGGG-HSA, followed by Gly2-GLP-1-VTR-HSA, Gly2-GLP-1-SARSVRA-HSA, and Gly2-GLP-1-GRSRVTRSV-HSA.In vivo PD test exhibited hypoglycemic activity that was the highest in Gly2-GLP-1-VTR-HSA, followed by Gly2-GLP-1-SARSVRA-HSA, Gly2-GLP-1-GRSRVTRSV-HSA, and Gly2-GLP-1-GGGGG-HSA.Conclusion GLP-1 can be released from fusion proteins with full activity after the introduction of protease cleavage sites.Releasable fusion proteins at an appropriate release rate have the most balanced PK and PD.

Objective:To characterize the injury to the ipsilateral ankle joint after low energy spiral fracture of the distal tibia.Methods:A retrospective study was conducted to analyze the 80 patients with distal tibial spiral fracture who had been treated at Department of Traumatic Orthopedics, Affiliated Hospital of Jining Medical University from March 2010 to March 2021. There were 61 males and 19 females with an age of (43.5±12.5) years. Their mean follow-up time was 67.0 (38.5, 90.0) months. All patients underwent preoperative X-ray examination, 64 ones preoperative CT examination, and 30 ones preoperative MRI examination. Of the 80 patients, 3 received conservative treatment with plaster external fixation, 3 closed reduction and intramedullary nail fixation, and 74 plate fixation. Statistically analyzed were incidence of posterior malleolus fracture, characteristics of posterior malleolus fracture lines, normal matching rate of the ipsilateral ankle joint, positive rate of intraoperative Cotton test or stress external rotation test of ipsilateral ankle joint, positive rates of passive pronation-external rotation and supination-external rotation stress tests during follow-up, incidences of short-term ankle pain (≤2 years) and medium-long term pain (>2 years) after operation, injuries to the anterior inferior tibiofibular ligament, the deep medial malleolus deltoid ligament and the posterior malleolus, and incidence of ankle injury.Results:The diagnostic rate for posterior malleolus fracture was 16.3% (13/80) on X-ray film, 60.9% (39/64) on CT and 76.7% (23/30) on MRI. 74.5% (35/47) of the posterior malleolus fracture lines opened on the lateral side. The normal matching rate of the ipsilateral ankle joint was 96.3% (77/80). The positive rates of intraoperative Cotton test and stress external rotation test were 34.8% (8/23) and 7.1% (1/14), respectively. The positive rates of passive pronation-external rotation and supination-external rotation stress tests during follow-up were 46.2% (12/26) and 34.6% (9/26). The incidences of postoperative short term (≤2 years) and medium-long term (>2 years) ankle pain were 37.7% (29/77) and 20.8% (16/77). MRI examination showed that the rates of injury to the anterior inferior tibiofibular ligament, deep medial malleolus deltoid ligament and posterior malleolus were 80.0% (24/30), 80.0% (24/30) and 76.7% (23/30). The incidence of ankle injury was 88.8% (71/80).Conclusions:It is highly probable that spiral fracture of the distal tibia is complicated with ipsilateral ankle injury. The medial malleolus, lateral malleolus, and posterior malleolus are prone to the following hidden injuries while the ankle joint is normally matched in the most cases: injury to the deep deltoid ligament in different degrees, rupture of the inferior tibiofibular anterior ligament and posterior malleolus fracture. Therefore, the ankle injury is likely to be missed in diagnosis. The secondary torsion injuries to the pronation-external rotation and supination-external rotation at the leg are likely to cause ipsilateral ankle injury.
