OBJECTIVE: To explore the laws of traditional Chinese medicine (TCM) syndromes in unstable angina, and to establish the preliminary diagnostic criteria for TCM syndromes. METHODS: Multi-center prospective research on TCM syndromes in 815 cases of unstable angina was done with the nonlinear dimension reduction by factor analysis. RESULTS: There were five extracted factors in factor analysis: F1, F2, F3, F4 and F5. F1 was yin deficiency of heart and kidney, F2 was deficiency of both heart and spleen, F3 was intermingled phlegm and blood stasis, F4 was qi deficiency and blood stasis, and F5 was yang deficiency and coagulated cold. Qi deficiency and blood stasis (F4) syndrome accounted for the maximum proportion. The diagnostic criteria for TCM syndromes were preliminarily and respectively established. CONCLUSION: Qi deficiency and blood stasis is the key factor of pathogenesis. The factor analysis can help us classify traditional Chinese medicine syndromes and establish the preliminary diagnostic criteria.

Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

OBJECTIVE: To discuss the distribution laws of traditional Chinese medicine (TCM) syndrome factor and their combination in coronary heart disease (CHD), and to study the correlation between the TCM syndrome factor combination and cardiac function as well as blood-lipid. METHODS: The parameters of the cardiac function of 300 patients with a final diagnosis of CHD by coronary angiography were measured by echocardiography, and the levels of blood lipids in the CHD patients were detected. An analysis of the correlation was done between the TCM syndrome factor combination and cardiac function as well as blood-lipid in CHD. RESULTS: The TCM syndrome factor combinations of CHD were blood stasis due to qi deficiency, qi and yin deficiency, intermingled phlegm and blood stasis, and yang deficiency and blood stasis. The ejection fraction of CHD patients with yang deficiency and blood stasis was markedly decreased. The levels of triglyceride and low-density lipoprotein cholesterol in CHD patients with intermingled phlegm and blood stasis were markedly increased, and the level of triglyceride in CHD patients with qi and yin deficiency was markedly increased too. CONCLUSION: The treatment of CHD should aim directly at the symptoms and causes. It is also proved that some compound traditional Chinese herbal medicines for supplementing qi and activating blood circulation, nourishing yin and resolving phlegm, and activating yang should be used in treatment of CHD. In cases of CHD with low cardiac function, particular emphasis should be laid on activating yang and blood circulation, while in cases of CHD with blood-lipid disturbance, particular emphasis should be laid on resolving phlegm and activating blood circulation, replenishing qi and nourishing yin.

Objective To achieve personalized assessment of cumulated activity distribution in patients undergoing 18F-FDG PET scans using the biokinetic model based on the single-time-point PET images.Methods A biokinetic compartmental model for the organs of interest was established,and the variation of activities in each compartment was described as a set of differential equations.The PET image data at a specific time point of each patient was used to obtain the kinetic model parameters which were then optimized by a simulated annealing algorithm to calculate the cumulated activity of each organ.Additionally,the effects of different voiding patterns on the cumulated activity of the bladder were analyzed.Considering the heterogeneity of radioactive nuclide distribution in organs,a whole-body cumulated activity distribution map was computed,and the accuracy of the proposed method was evaluated by comparison with the existing methods.Results For the 11 cases analyzed in the study,the calculation results of the biokinetic model generally showed a good agreement with experimental data,with an average deviation of less than 15%.Meanwhile,under different urinary excretion conditions,the average cumulated activity in the bladder differed by up to 2.4 times,indicating the positive significance of enforced urination in reducing radiation exposure.The comparison with the biokinetic data obtained from ICRP Publication 128 revealed relatively large deviations for certain organs such as the brain and heart,with standard deviations of 61.0%and 46.3%,respectively.Conclusion The constructed biokinetic model can effectively estimate the individualized cumulated activity distribution in patients undergoing PET scans,providing valuable insights for the internal dosimetry assessment.

BACKGROUND: In the process of bone defect healing, the use of biological materials loaded with drugs for local defect intervention can accelerate the repair of the defect, which provides a new method for the local treatment of bone defects. OBJECTIVE: To introduce the local application of bone tissue engineering scaffolds loaded with bisphosphonates in bone defect repair and to summarize the effects of bone tissue engineering scaffolds as a drug delivery system on the bone defect healing. METHODS: The authors retrieved PubMed, Web of Science, Springerlink, Medline, WanFang and CNKI databases with "bisphosphonates, alendronate, zoledronate, bone defect, bone tissue engineering" as key words for relevant articles published from 2006 to 2018. Initially, 235 articles were retrieved, and finally 70 articles were selected for further analysis. RESULTS AND CONCLUSION: Bisphosphonate drug is an effective inhibitor of osteoclast dissolution. It can form a drug sustained release system on the local defect by being loaded to composite scaffolds, promote the formation of new bone and accelerate the healing of the defect. For the drug delivery system of bisphosphonates, suitable scaffold materials are crucial to the osteogenic effect of composite scaffolds in the defect area. At present, the carrier materials used for bisphosphonate-loaded composite scaffolds are mainly divided into organic materials and inorganic materials. Most polymeric organic materials can directly load bisphosphonates to form good drug sustained release in the local area and obviously exert their pro-osteogenic effects, while natural materials and most inorganic materials are often combined with other materials to form composite materials as carriers to optimize the carrier performance. Most studies have also confirmed that these composite materials loaded with bisphosphonates in the defect area exert osteogenic effect in the defect area.
