Mechanism of Modified Liuwei Dihuangtang in Bone Protection of CKD-MBD Model Rats： An Exploration Based on Klotho-FGF23 Axis / 中国实验方剂学杂志

Objective:To observe the effects of modified Liuwei Dihuangtang on serum fibroblast growth factor 23 （FGF23）， full-length intact parathyroid hormone （iPTH）， and 1，25-dihydroxyvitamin D₃［1，25（OH）₂D₃］ levels and Klotho and FGF23 protein expression in renal and bone tissues of rats exposed to high phosphorus combined with adenine， so as to explore the mechanism of modified Liuwei Dihuangtang against renal osteopathy. Method:One hundred and thirty healthy adult SD rats were randomly divided into five groups， namely normal group（<italic>n</italic>=10），high phosphorus group（<italic>n</italic>=30），model group（<italic>n</italic>=30），modified Liuwei Dihuangtang group（<italic>n</italic>=30） ， and calcitriol group（<italic>n</italic>=30），and rats in each group were further classified based on three time points， namely 8，10， and 12 weeks. Rats in the normal group were fed with normal diet， the ones in the high phosphorus group with high phosphorus diet， and those in the other groups with adenine and high phosphorus diet for inducing renal osteopathy. Rats in the normal group，high phosphorus group， and model group were intragastrically administered with distilled water （10 mL·kg^-1·d^-1），the ones in the modified Liuwei Dihuangtang group with modified Liuwei Dihuangtang （2.556 g·kg^-1·d^-1） ， and those in the calcitriol group with calcitriol （0.09 μg·kg^-1·d^-1）. Result:Compared with the normal group and high phosphorus group at the weeks of 8，10 and 12，the model group displayed significantly elevated blood urea nitrogen（BUN），serum creatinine（SCr），serum phosphorus，iPTH，FGF23，renal interstitial fibrosis score， and FGF23 expression in renal and bone tissues， but lowered serum calcium and 1，25（OH）₂D₃ and Klotho protein expression in renal and bone tissues（<italic>P</italic><0.05 ，<italic>P</italic><0.01）. Compared with the model group at the weeks of 8，10 and 12， the modified Liuwei Dihuangtang and calcitriol both significantly decreased the serum BUN，SCr，serum phosphorus，iPTH， FGF23， tubulointerstitial semi-quantitative score， and FGF23 expression in renal and bone tissues， while increased the serum calcium，1，25（OH）₂D₃， and Klotho protein expression in renal and bone tissues （<italic>P</italic><0.05，<italic>P</italic><0.01）. There was no significant difference in the above-mentioned indexes between the modified Liuwei Dihuangtang group and the calcitriol group at the same time point. Conclusion:Klotho-FGF23 axis is probably involved in renal osteopathy. The modified Liuwei Dihuangtang effectively improves renal function，alleviates pathological changes in renal and bone tissues，and regulates calcium and phosphorus metabolism to protect the bone， which is related to its regulation of Klotho-FGF23 axis.

Treatment effect of hemifacial dysplasia by injecting transplantation of autologous tissue in the second stage surgery for total auricle reconstruction / 中华耳鼻咽喉头颈外科杂志

Objective: To observe the treatment effect of hemifacial dysplasia by injecting transplantation of autologous dermis and fat granules in the second stage surgery for total auricle reconstruction. Methods: From March 2013 to March 2018, 57 patients with unilateral microtia and mild-to-moderate hemifacial dysplasia were divided into concurrent treatment group (32 cases, including 13 females and 19 males and aged 6-33 years old with an average age of 12.5 years) and traditional treatment group (25 cases, including 10 females and 15 males and aged 6-21 years old with an average age of 11.3 years) according to the different surgical methods. Modified Nagata method of auricular reconstruction was chosen, in the second stage surgery (cranial ear angle plasty), patients in concurrent treatment group received the treatment of hemifacial dysplasia with autologous dermal and fat injection transplantation at the same time; Patients in traditional treatment group only received cranial ear angle plasty. Statistical analysis of the two groups of patients was carried out for the average operation time, the average length of hospital stay, the incidence of common complications and postoperative satisfaction rate. SPSS 21.0 software was used for statistical analysis. Results: The mean operation time of the concurrent treatment group (282.0±3.4)min was longer than that of the traditional treatment group (243.0±3.1)min, and the difference was statistically significant (t=9.884, P<0.05). There were no statistically significant differences in the average length of stay between the the concurrent treatment group (9.4±0.3)d and the traditional treatment group(9.5±0.2)d, t=0.256, P>0.05. There were no statistically significant differences in the incidence of common surgical complications between the concurrent treatment group (12.5%, 4/32) and the traditional treatment group(12.0%, 3/25), χ2=0, P>0.05. Postoperative satisfaction rate of the concurrent treatment group(90.6%, 29/32) was significantly higher than that of the traditional treatment group(56.0%, 14/25), the difference was statistically significant (χ2=9.081, P<0.05). Conclusions: Auricular reconstruction with treatment of hemifacial dysplasia should not significantly increase the average length of stay and the incidence of common complications compared with auricular reconstruction alone. Although the operation time is slightly extended, the scheme of concurrent treatment can reduce the times of operations, save medical resources and increase the satisfaction rate of patients.

Traditional Chinese medicine for prevention and treatment of hepatocellular carcinoma: A focus on epithelial-mesenchymal transition / 中西医结合学报

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant cancers worldwide. Epithelial-mesenchymal transition (EMT), which endows epithelial cells with mesenchymal properties, plays an important role in the early stages of metastasis. Conventional cancer therapies have promising effects, but issues remain, such as high rates of metastasis and drug resistance. Thus, exploring and evaluating new therapies is an urgent need. Traditional Chinese medicines (TCMs) have been acknowledged for their multi-target and coordinated intervention effects against HCC. Accumulating evidence indicates that TCM can inhibit the malignancy of cells and the progression of EMT in HCC. However, studies on the effects of TCM on EMT in HCC are scarce. In this review, we summarized recent developments in anti-EMT TCMs and formulae, focusing on their underlying pharmacological mechanisms, to provide a foundation for further research on the exact mechanisms through which TCM affects EMT in HCC.

The purpose of this study is to observe the protective effect and molecular mechanism of SDX on the function damage of human umbilical vein endothelial cells induced by pregnancy serum of PE.Methodsthe indicated concentrations of SDX (0, 0.1, 0.3, 1, 3, 10, 30 LSU/mL) were used to interfere with HUVEC and Ea.hy926 cells. CCK8 and Matrigel methods were used to detect cell proliferation and tube formation. The normal pregnant women serum (NPS) or PE patients serum (PES) which collected at the 12 th week of pregnancy and the effective concentration of SDX were used to intervene the cells. Matrigel methods were used to observe the protective effect of SDX on endothelial function damage which induced by pathological serum. The secretion level of sFLT-1 and PlGF in supernatant were determined by ELISA.ResultsCompared with the control group, high concentration of SDX inhibited the proliferation of endothelial cells. SDX significantly promoted the tube formation activity wiht a peak at 0.3 LSU/mL (P<0.01). PES damaged the tube formation activity. 0.3 LSU/mL SDX protected cells from tube formation damage which induced by PES (P<0.01). PES promoted the secretion of sFLT-1 and inhibit the secretion of PlGF, while 0.3 LSU/mL SDX reversed the secretion of sFLT-1 and PlGF induced by PES (P<0.01).Conclusion0.3 LSU/mL SDX can protect endothelial cells from PES induced endothelial dysfunction, which is associated with the secretion balance regulation of sFLT-1 / PlGF.

Objective: To explore the clinical efficacy and safety of modified Huqianwan in treatment of rheumatoid arthritis (RA) liver-kidney Yin deficiency syndrome, and investigate its possible mechanism. Method: A total of 184 patients with RA liver-kidney Yin deficiency syndrome were randomly divided into Chinese medicine group (62 cases), western medicine group (57 cases) and integrated Chinese and western medicine group (65 cases) according to the digital table method. The patients in Chinese medicine group were treated with Huqianwan; the patients in western medicine group were treated with methotrexate tablets and leflunomide tablets; and the patients in integrated Chinese and western medicine group received Huqianwan+methotrexate tablets and leflunomide tablets,with a treatment course of 12 weeks in all groups. The pain visual analog scale (VAS), swelling and tenderness scores of 28 joints (DAS28), average hands grip strength, morning stiffness time and liver-kidney Yin deficiency syndrome differentiation of traditional Chinese medicine (TCM) syndrome score were compared between groups before and after treatment. The changes of erythrocyte sedimentation rate (ESR), C reactive protein (CRP), immunoglobulin (Ig) G, tumor necrosis factor-alpha (TNF-α) and rheumatoid factor (RF) were detected in all groups after treatment. Clinical efficacy, and incidence of adverse reactions such as gastrointestinal response, liver injury, leukopenia, serum glutamate oxaloacetic aminotransferase (GOT) and platelet (PLT) level changes were compared between the groups, so as to investigate the efficiency and safety of the different medicines. Result: After 12 weeks of treatment, the total clinical effective rate was 79.0%, 80.7%, and 92.3% respectively in Chinese medicine group, western medicine group, and integrated Chinese and western medicine group; the integrated Chinese and western medicine group was significantly better than the Chinese medicine group and western medicine group (PPPPConclusion: The efficacy in treating RA liver and kidney Yin deficiency syndrome shows no significant difference between modified Huqianwan and methotrexate tablets+leflunomide tablets. In the treatment of RA liver and kidney Yin deficiency syndrome, Huqianwan has fewer adverse reactions. Huqianwan combined with methotrexate tablets+leflunomide tablets is superior to that in methotrexate tablets+leflunomide tablets in treatment of RA liver-kidney Yin deficiency syndrome.

Application of scenario simulation teaching in cardiopulmonary resuscitation training for junior surgical residents / 中华医学教育探索杂志

Objective To explore the effect of scenario simulation teaching method in the training of cardiopulmonary resuscitation (CPR) for junior surgical residents. Methods 133 junior residents (working life<3 years) in the author's hospital rotating Cardiac Surgery department were selected and divided into control group (n=65) and observation group (n=68), in which the control group adopted traditional classroom teaching: teacher explanation-demonstration-student practice-teacher counseling; the observation group adopted scenario simulation teaching: teacher explanation-demonstration-student practice-teacher counseling scenario simulation. Before and after training, two groups both received the CPR theory and double operation assessment , comparing the difference of assessment scores between groups before and after training . Results There was no statistically significant difference in the demographic characteristics between the two groups. The assessment scores of CPR theory and operation were improved in both groups after training, and there were significant differences (P=0.000). There were no statistically significant differences in the CPR theory and operation assessment scores between the two groups before training (P>0.05);compared with the scores of CPR operation between the two groups after training, the observation group [(84.62±3.94)] was significantly higher than that of the control group [(79.68±5.45)] and there were significant statistical differences (P=0.000), while there was no statistically significant difference in CPR theory assessment scores between the two groups (P>0.05). Conclusions Both traditional classroom teaching and scenario simulation teaching methods could improve the CPR theory and skill level of the surgical junior resident, but situa tional simulation teaching method is better than traditional classroom teaching method in improving students' CPR performance.
