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 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 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.

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.

Objective:To study the effects of different calcium ion concentrations on epithelial mesenchymal transformation (EMT) of human peritoneal mesothelial cell (HPMC) via endoplasmic reticulum stress (ERS).Methods:HPMC cell line HMrSV5 was cultured in vitro and treated in groups. The cells in the control group, high calcium group 1, and high calcium group 2 were treated with medium containing calcium ion concentrations of 1.25, 1.75, and 2.25 mmol/L, respectively. The solvent control group was treated with medium containing 1.25 mmol/L physiological calcium ion concentration and 0.1% dimethyl sulfoxide (DMSO), the high calcium+solvent group was treated with medium containing 2.25 mmol/L calcium ion concentration and 0.1% DMSO, the high calcium+4-phenylbutyric acid (4-PBA) group was treated with medium containing 2.25 mmol/L calcium ion concentration and 1 mmol/L ERS inhibitor 4-PBA, and each group was treated for 48 hours. Morphological changes of cells in each group were observed under light microscope. The expressions of epithelial cell phenotype marker zonula occluden-1 (ZO-1) and mesenchymal cell phenotype marker α-smooth muscle actin (α-SMA) in the cells were observed by immunofluorescence staining. The expressions of EMT marker genes E-cadherin, ZO-1, α-SMA and Vimentin were detected by fluorescence quantitative polymerase chain reaction (PCR). The expressions of ERS marker proteins phosphorylated protein kinase R-like endoplasmic reticulum kinase (p-PERK), phosphorylated eukaryotic initiation factor 2α (p-eIF2α), transcription activating factor 4 (ATF4) and C/EBP homologous protein (CHOP) were detected by Western blotting. Results:Compared with the control group, the morphology of HMrSV5 cells became slender and fibrotic, the fluorescence intensity of ZO-1 increased, and the fluorescence intensity of α-SMA decreased in high calcium 1 and high calcium 2 groups, indicating that the cells transformed from epithelial cells to mesenchyme cells. The mRNA expressions of E-cadherin and ZO-1 were significantly decreased, while the mRNA expressions of α-SMA and Vimentin and the protein expressions of p-PERK, p-eIF2α, ATF4 and CHOP were significantly increased, moreover, the expressions of the above marker genes or proteins in the high calcium 2 group was more obvious than those in the high calcium 1 group [E-cadherin mRNA (2 -ΔΔCt): 0.53±0.05 vs. 0.75±0.09, ZO-1 mRNA (2 -ΔΔCt): 0.42±0.06 vs. 0.69±0.06, α-SMA mRNA (2 -ΔΔCt): 1.81±0.16 vs. 1.32±0.14, Vimentin mRNA (2 -ΔΔCt): 2.05±0.22 vs. 1.48±0.16, p-PERK protein (p-PERK/β-actin): 0.81±0.09 vs. 0.59±0.06, p-eIF2α protein (p-eIF2α/β-actin): 0.87±0.10 vs. 0.50±0.06, ATF4 protein (ATF4/β-actin): 0.93±0.10 vs. 0.72±0.06, CHOP protein (CHOP/β-actin): 0.79±0.09 vs. 0.46±0.04, all P < 0.05]. Compared with the solvent control group, the morphological changes of cells, the expressions of EMT marker genes and ERS marker proteins after high calcium ion concentration of 2.25 mmol/L were consistent with those in the high calcium 2 group than control group. Compared with the high calcium+solvent group, the cell morphology recovered the characteristics of polygonal and pebble-like epithelial cells in the high calcium+4-PBA group, the fluorescence intensity of ZO-1 increased, the fluorescence intensity of α-SMA decreased, and the mRNA expressions of E-cadherin and ZO-1 in the cells were significantly increased [E-cadherin mRNA (2 -ΔΔCt): 0.86±0.09 vs. 0.57±0.04, ZO-1 mRNA (2 -ΔΔCt): 0.81±0.06 vs. 0.48±0.05, both P < 0.05], the mRNA expressions of α-SMA and Vimentin and the protein expressions of p-PERK, p-eIF2α, ATF4 and CHOP were significantly decreased [α-SMA mRNA (2 -ΔΔCt): 1.21±0.13 vs. 1.77±0.15, Vimentin mRNA (2 -ΔΔCt): 1.30±0.14 vs. 1.94±0.20, p-PERK protein (p-PERK/β-actin): 0.38±0.04 vs. 0.92±0.11, p-eIF2α protein (p-eIF2α/β-actin): 0.34±0.05 vs. 1.05±0.13, ATF4 protein (ATF4/β-actin): 0.57±0.06 vs. 0.97±0.11, CHOP protein (CHOP/β-actin): 0.51±0.04 vs. 0.90±0.12, all P < 0.05]. Conclusion:High calcium ion concentrations of 1.75 mmol/L and 2.25 mmol/L promote EMT of HPMC via activating ERS.

Objective:To analyze the molecular epidemiological characteristics of the Corona virus disease 2019 (COVID-19) cases in Shijiazhuang, which can reveal the origin of the outbreak and provide a scientific basis for COVID-19 prevention and control.Methods:From January 2 to January 8, 2021, a total of 404 samples from 170 COVID-19 cases were collected from the Shijiazhuang Fifth Hospital. The consensus sequence of 2019 novel Coronavirus(2019-nCoV) was obtained through multiplex polymerase chain reaction-based sequencing. The sequences of 170 COVID-19 cases were analyzed by the PANGOLIN, and the data were statistically analyzed by T-test.Results:Among the 404 COVID-19 samples, a total of 356 samples obtained high quality genome sequences (>95%,100×sequencing depth). The whole genome sequences of 170 COVID-19 cases were obtained by eliminating repeated samples. All 170 sequences were recognized as lineage B1.1 using PANGOLIN. The number of single nucleotide polymorphism arrange from 18-22 and most of the single nucleotide polymorphism were synonymous variants. All of 170 genomes could be classified into 48 sub-groups and most of the genomes were classified into 2 sub-groups (66 and 31, respectively).Conclusions:All cases in this study are likely originated from one imported case. The viruses have spread in the community for a long time and have mutated during the community transmission.
