BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

Based on the holistic view of "spleen-vessels-heart-spirit" system， this article explores the pathogenesis and progression of atrial fibrillation. It is proposed that the onset of atrial fibrillation is due to failure of the spleen to transport and disharmony of blood vessels； phlegm and blood stasis obstructing the collaterals and damage to the heart structure are the basis of its pathogenesis； the unclear mind and disorder of body and spirit are the causes of its progression. Based on the characteristics of pathological changes in different stages of the disease， it is proposed that early treatment should focus on restoring the middle jiao， clearing and promoting blood vessels， using modified Yigong Powder （异功散）； during the progression of the disease， treatment should remove blood stasis and phlegm， nourish heart and protect the pulse， using self-prescribed modified Mengshi Tongmai Decoction （礞石通脉汤）； meanwhile， calming mind and stabilizing palpitations， and regulating spirit should be sequentially incorporated， with self-prescribed Jiazao Ningmai Decoction （甲枣宁脉汤） or Shenying Dingji Decoction （参英定悸汤） and modified as appropriate. Clinical treatment should focus on the whole disease course of atrial fibrillation， implementing stage-based treatments to enable early intervention and holistic regulation.

PURPOSE: To compare the effects of empirical and modified hemostatic resuscitation for liver blast injury combined with seawater immersion. METHODS: Thirty rabbits were subjected to liver blast injury combined with seawater immersion, and were then divided into 3 groups randomly (n = 10 each): group A (no treatment after immersion), group B (empirical resuscitation with 20 mL hydroxyethyl starch, 50 mg tranexamic acid, 25 IU prothrombin complex concentrate and 50 mg/kg body weight fibrinogen concentrate), and group C (modified resuscitation with additional 10 IU prothrombin complex concentrate and 20 mg/kg body weight fibrinogen concentrate based on group B). Blood samples were gathered at specified moments for assessment of thromboelastography, routine coagulation test, and biochemistry. Mean arterial pressure, heart rate, and survival rate were also documented at each time point. The Kolmogorov-Smirnov test was used to examine the normality of data distribution. Multigroup comparisons were conducted with one-way ANOVA. RESULTS: Liver blast injury combined with seawater immersion resulted in severe coagulo-fibrinolytic derangement as indicated by prolonged prothrombin time (s) (11.53 ± 0.98 vs. 7.61 ± 0.28, p＜0.001), activated partial thromboplastin time (APTT) (s) (33.48 ± 6.66 vs. 18.23 ± 0.89, p＜0.001), reaction time (R) (min) (5.85 ± 0.96 vs. 2.47 ± 0.53, p＜0.001), decreased maximum amplitude (MA) (mm) (53.20 ± 5.99 vs. 74.92 ± 5.76, p＜0.001) and fibrinogen concentration (g/L) (1.19 ± 0.29 vs. 1.89 ± 0.32, p = 0.003), and increased D-dimer concentration (mg/L) (0.38 ± 0.32 vs. 0.05 ± 0.03, p = 0.005). Both empirical and modified hemostatic resuscitation could improve the coagulo-fibrinolytic states and organ function, as indicated by shortened APTT and R values, decreased D-dimer concentration, increased fibrinogen concentration and MA values, lower concentration of blood urea nitrogen and creatine kinase-MB in group B and group C rabbits in comparison to that observed in group A. Further analysis found that the R values (min) (4.67 ± 0.84 vs. 3.66 ± 0.98, p = 0.038), APTT (s) (23.16 ± 2.75 vs. 18.94 ± 1.05, p = 0.001), MA (mm) (60.10 ± 4.74 vs. 70.21 ± 3.01, p < 0.001), and fibrinogen concentration (g/L) (1.68 ± 0.21 vs. 1.94 ± 0.16, p = 0.013) were remarkably improved in group C than in group B at 2 h and 4 h after injury. In addition, the concentration of blood urea nitrogen (mmol/L) (24.11 ± 1.96 vs. 21.00 ± 3.78, p = 0.047) and creatine kinase-MB (U/L) (85.50 ± 13.60 vs. 69.74 ± 8.56, p = 0.013) were lower in group C than in group B at 6 h after injury. The survival rates in group B and group C were significantly higher than those in group A at 4 h and 6 h after injury (p < 0.001), however, there were no statistical differences in survival rates between group B and group C at each time point. CONCLUSIONS Modified hemostatic resuscitation could improve the coagulation parameters and organ function better than empirical hemostatic resuscitation.

Objective To evaluate the resuscitation efficacy of novel lyophilized platelets(LP,thrombin-stimulated platelets)combined with lactated Ringer's(LR)solution in rabbits with hemorrhagic shock and seawater immersion.Methods Fifty rabbits were randomly assigned to 5 groups(Groups A,B,C,D and E,n=10).After all rabbits were anesthetized with 3%pentobarbital sodium at a dose of 1 mL/kg,soft tissue injury was inflicted in the left lower limb.The blood loss from the soft tissue injury was quantified after gauze hemostasis.The right lower limb was subjected to femoral artery catheterization,followed by blood withdrawal equivalent to 26%of the total blood volume of the rabbit.The rabbits were then vertically immersed in 3%artificial seawater,with the water level reaching above the xiphoid process,and were retrieved in 15 min later.Resuscitation strategies were applied to the rabbits from different group:Group A(no resuscitation),Group B(resuscitation with LR solution),Group C(resuscitation with LR solution and fresh platelets),Group D(resuscitation with LR solution and LP),and Group E(resuscitation with LR solution and novel LP).Coagulation function test,routine blood test,blood gas analysis,and thromboelastography were conducted at baseline and at 1,2 and 4 h after injury.Results The LP and rabbit model of hemorrhagic shock and seawater immersion were successfully prepared.At 1 h after injury,the mean arterial pressure(MAP)of Groups C,D and E(infused with platelet preparations)was significantly higher than that of Group A(without resuscitation,P<0.05);the lactate(Lac)content of Group C was obviously lower than that of Groups A and B(P<0.05);the base excess(BE)and blood urea nitrogen(BUN)levels of Groups C,D and E were notably lower than those of Groups A and B(P<0.05);and the prothrombin time(PT)of Group A was significantly longer than that of before injury(P<0.05).At 2 h after injury,the MAP of Groups C and D was significantly higher than that of Groups A and B,and that of Group E was notably higher than that of Group A(P<0.05);the Lac content of Groups C and E was obviously lower than that of Groups A and B,while that of Group D was also lower than that of Group A(P<0.05);the BE and BUN levels of Groups C,D and E were remarkably lower than those of Groups A and B(P<0.05);the maximum amplitude(MA)value of Group C was higher than that of Group A,while the value of Groups A and D at this time was significantly lower than the corresponding value before injury(P<0.05);and the activated partial clotting time(APTT)of Groups A and D was statistically longer than the corresponding baseline time(P<0.05).At 4 h after injury,the MAP of Groups C,D,and E was higher than that of Groups A and B,and that of Group B was higher than that of Group A(P<0.05);the Lac and BUN levels of Groups C,D,and E were lower than those of Groups A and B(P<0.05);the BE level of Groups C and D were lower than those of Groups A and B(P<0.05);the MA value of Groups B,C,and E were higher than those of Group A(P<0.05),while the MA value and APTT value of Groups A and D were significantly lower than their corresponding baseline values(P<0.05).Conclusion For rabbits with hemorrhagic shock and seawater immersion,the novel LP combined with LR solution can significantly increase the MAP level,reduce Lac content,and sustainably maintain blood clot firmness and coagulation function.

Paroxysmal atrial fibrillation can be attributed to the category of xinji （palpitations） and zhangchong （severe palpitations） in traditional Chinese medicine， and its onset has the characteristics of urgency， change， and movement， which is similar to the characteristics of diseases induced by wind pathogen. It is believed that the internal movement of wind pathogen runs through the whole course of this disease， and palpitations due to wind as the direct pathogenesis. Palpitations caused by wind pathogen showed different characteristics of deficiency and excess pattern. In the acute exacerbation period， excess wind is the main cause of disease. For excessive heat generating wind， the treatment is to clear the liver and extinguish wind by self-modified Lingxia Qinggan Decoction （羚夏清肝汤）； for blood stasis generating wind， the treatment is to remove blood stasis and stop wind by self-modified Yandan Limai Decoction （延丹理脉汤）； for phlegm-heat accumulation with wind， the treatment is to dissolve phlegm and eliminate wind by self-modified Lianlou Danxing Decoction （连蒌胆星汤）. In the prolonged recovery period， deficiency wind is more common. For stirring of wind due to yin deficiency， the treatment is to nourish yin and extinguish wind by self-modified Zaoshao Zhenzhu Deoction （枣芍珍珠汤）； for spleen deficiency generating wind， the treatment is to strengthen spleen and nourish wind by self-modified Shenying Dingji Deoction （参英定悸汤）. Clinical prescriptions closely follow the characteristics of wind， weigh the changes of deficiency and excess， tailor with the patterns， and regulate qi and blood of the zang-fu organs， in order to extinguish wind and arrest convulsion.

Objective To investigate the role of silencing regulatory protein 1(Sirt1)in the regulation of Vibrio vulnificus sepsis-induced macrophage apoptosis and the molecular mechanisms.Methods Mouse RAW264.7 macrophages which stably overexpressed Sirt1 were constructed and screened by genistein G418.CCK-8 analysis was used to detect the proliferation of cells in the control group and Sirt1-Flag group.The changes of expression levels of apoptosis-associated protein poly ADP-ribose polymerase(PARP),cleaved-PARP,caspase3,cleaved-caspase3 and acetylated p53 in different treatment groups were detected via Western blotting.A Vibrio vulnificus sepsis model in mice was established,and the expression levels of apoptosis-associated protein cleaved-caspase3 in the lung,spleen and liver of mice of different treatment groups were detected by immunohistochemistry.Results Overexpression of Sirt1 reduced VVC-induced RAW264.7 cell damage.Overexpression of Sirt1 as well as RSV pretreatment lowered the expression of apoptosis-associated protein cleaved-PARP,cleaved-caspase3 and acetylated p53 in VVC-stimulated RAW264.7 cells and mouse peritoneal macrophages.In the mouse model of Vibrio vulnificus sepsis,therapeutic administration of RSV reduced the expression of apoptosis-associated protein marker cleaved-caspase3 in lung,spleen and liver tissues.Conclusion Sirt1 can inhibit p53 acetylation and reduces apoptosis in mouse macrophages,which helps protect against Vibrio vulnificus sepsis.

Objective:To conduct a retrospective analysis of efficacy and safety of different conversion schemes of tacrolimus to slow-release dosage forms for recipients in stable phase after renal transplantation to provide rationales for the conversion strategy of tacrolimus.Methods:From January 2020 to June 2020, clinical data were reviewed for 101 kidney transplant recipients converting from common tacrolimus dosage form to tacrolimus sustained-release dosage form during postoperative stable period.There were 62 males and 49 females with an age range of 19 to 69 years.They were divided into two groups according to iso-dose and incremental-dose switching schemes.The common dosage form of tacrolimus was converted into a sustained-release dosage form with different conversion doses, They were divided into two groups of 1∶1 conversion( n=55)and >1∶1 conversion( n=46). The clinical parameters of serum creatinine(Scr), blood urea nitrogen(BUN), alanine aminotransferase(ALT)and aspartate aminotransferase(AST), alkaline phosphatase(ALP), serum albumin(ALB), white blood cell count(WBC), urinary white blood cell(UWBC), hemoglobin(Hb)and fasting blood glucose(Glu)were compared between two groups after conversion. Results:Regarding numerical change trend after switching to tacrolimus sustained-release dosage form, drug dose/variation trend was smaller and blood drug concentration more stabilized.In two subgroups converted by 1∶1 and 1>1 initial dose, change trend of dose/blood concentration in 1∶1 conversion group appeared to be more stable.However, no inter-group difference existed in long-term parameters.Scr was lower at 1 week and 3 months after switching to extended-release dosage form( P<0.05)and BUN was lower at 2 weeks( P<0.05). In addition, at 5 months after conversion, ALT and AST significantly improved as compared with common dosage form( P<0.05). Significant differences existed in urinary WBC(UWBC)at 2/3 weeks( P<0.05). After switching for 2 weeks, hemoglobin significantly improved compared with common dosage form( P<0.05). No significant differences existed in ALP, ALB or Glu at other timepoints and pre-conversion( P>0.05). In 1∶1 switch group, renal function tended to improve.At 2 weeks, BUN was lower than pre-conversion; at 1/3 weeks, Scr was lower than pre-conversion( P<0.05). In addition, there was also a trend of improvement in liver function in 1∶1 conversion group.At 1 week and 5 months, ALT was lower than pre-conversion( P<0.05). However, no significant differences existed in AST, ALB, ALP, Glu, UWBC and serum WBC count at each timepoint between two different dose conversion groups( P>0.05). After conversion, intra-individual variability of tacrolimus trough concentration significantly improved( P<0.05). Conclusions:With the same safety and efficacy as common dosage form, sustained-release dosage form of tacrolimus may improve drug variability of individuals.When converting common dosage form into sustained-release dosage form, individual differences should be considered.While monitoring trough concentrations, proper doses should be adjusted on the basis of various clinical parameters.
