Jianghuanglian is one of the representative processed products of Coptidis Rhizoma for treating cold syndrome with drugs of heat nature， and ginger is used to restrict the bitter cold of Coptidis Rhizoma， which can be traced back to Bojifang， and it is suitable for stagnation of damp-heat in middle-jiao， cold-heat mutual knots and other symptoms. Jianghuanglian retains the alkaloids， phenylpropanoids and flavonoids of Coptidis Rhizoma， and also introduces gingerol components such as 6-gingerol in ginger， which has pharmacological activities such as anti-inflammatory， antibacterial， anti-tumor， and improving gastrointestinal function. The 2020 edition of Chinese Pharmacopoeia and many local processing specifications have included the traditional processing process and quality standards of Jianghuanglian， but the specific process parameters and quality standards are incomplete， which limits the production and clinical application of this processed product. By summarizing the processing history， process research， quality evaluation， pharmacodynamic and medicinal property changes and application of Jianghuanglian in the past 20 years， there are differences in the processing methods and standards in various provinces and cities， which are mainly reflected in the preparation method， dosage， processing process and quantitative standards of ginger juice. In addition， there are also certain differences in the changes of the main components of Jianghuanglian prepared from ginger or dried ginger， as well as their efficacy and medicinal properties. The research on the processing process of Jianghuanglian plays an important role in improving its quality standards， and this review can provide a reference for improving the quality evaluation system of Jianghuanglian.

Objective To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures.Methods Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively,and divided into open reduction and internal fixation group(posterior medial approach hollow anchor system fixation)and arthroscopic fixation group(Endobutton with loop plate fixation under arthroscopy).There were 20 patients in open reduction and internal fixation group,including 16 males and 4 females,aged from 26 to 74 years old with an average of(42.9±18.8)years old;13 patients on the left side and 7 patients on the right side;12 patients were classi-fied to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;14 patients were grade Ⅱ and 6 patients were grade Ⅲ in back drawer test.There were 18 patients in arthroscopic fixation group,including 11 males and 7 fe-males;aged from 24 to 70 years old with an average of(53.5±13.4)years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classifica-tion;11 patients were grade Ⅱ and 7 patients were grade Ⅲ in back drawer test.Operation time,blood loss,and quality of im-mediate reduction were compared between two groups.Knee range of motion,knee back drawer test,and International Knee Documentation Committee(IKDC)grading,KT2000 stability evaluation and Lysholm function score of knee joint were com-pared at 6 months after operation.Results All patients were followed up for 8 to 16 months with an average of(12.3±1.9)months.There were no complications such as incision infection,fracture malunion or non-union,and internal fixation loosening occurred.The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation.Operation time and blood loss in open reduction and internal fixation group were(56.4±7.1)min and(63.2±10.2)ml,while(89.9±7.4)min and(27.7±8.7)ml in arthroscopic fixation group,respectively,and had significant difference between two groups(P＜0.05).There were no differences in immediate reduction quality(x2=0.257,P=0.612),knee joint range of motion at 6 months after opertaion(t=0.492,P=0.626),knee joint rear drawer test(x2=0.320,P=0.572),IKDC classification of knee joint(x2=0.127,P=0.938),KT2000stability evaluation(x2=0.070,P=0.791),and knee Lysholmfunction score(t=0.092,P=0.282)between two groups.Conclusion Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixa-tion for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results,and arthroscopic surgery has less bleeding,but also has a longer learning curve and longer operation time than traditional inci-sion surgery.The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

Post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is one of the most common complications after endoscopic retrograde cholangiopancreatography(ERCP).Numerous PEP prediction models have been established based on different statistical methods at home and abroad.The PEP prediction model,as a tool for evaluating and screening high-risk populations,can provide a basis for medical staff to find high-risk PEP patients early and take effective preventive measures.In recent years,new PEP prediction models have appeared one after another,but there is still a lack of recognized reliable prediction models in clinic.This article reviews the research status of PEP risk prediction models,aim to provide a direction for establishing a more reliable,accurate,and practical PEP risk prediction model in the later period.

ObjectiveTo investigate the effect and mechanism of Zhenwutang on renal oxidative damage in the mouse model of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency via the nuclear factor erythroid 2-related factor-2 （Nrf2）/heme oxygenase-1 （HO-1）/glutathione peroxidase 4 （GPX4） signaling pathway. MethodTwenty-five 7-week-old SPF-grade male db/m mice and 95 7-week-old SPF-grade male db/db mice were adaptively fed for a week. A blank group was set with the db/m mice without treatment， and the other mice were administrated with Rhei Radix et Rhizoma decoction and hydrocortisone for the modeling of diabetic kidney disease with the syndrome of spleen-kidney Yang deficiency. The modeled mice were randomized into the model， irbesartan （25 mg·kg^-1）， and high-， medium-， low-dose （33.8， 16.9， 8.45 g·kg^-1） Zhenwutang groups （n=15） and administrated with corresponding drugs for 8 weeks. The survival status of mice was observed， and the traditional Chinese medicine （TCM） syndrome score was recorded. The indicators related to spleen-kidney Yang deficiency， fasting blood glucose （FBG）， and renal function indicators were determined. Hematoxylin-eosin staining was employed to observe the histopathological changes of the renal tissue in each group. Biochemical kits were used to determine the oxidative stress-related indicators in the renal tissue. Real-time polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Nrf2， HO-1， glutamate-cysteine ligase catalytic subunit （GCLC）， and GPX4 in the renal tissue of mice in each group. ResultCompared with the blank group， the modeling increased the TCM syndrome score （P<0.05）， elevated the estradiol （E₂） and FBG levels （P<0.05）， lowered the testosterone （T）， triiodothyronine （T3）， and tetraiodothyronine （T4） levels （P<0.05）， and weakened the renal function （P<0.05）. In addition， the modeling led to glomerular hypertrophy and glomerular mesangial and basal thickening， decreased the catalase （CAT） activity， total antioxidant capacity （T-AOC）， and glutathione （GSH） content （P<0.05）， increased the malondialdehyde （MDA） content （P<0.05）， and down-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. Compared with the model group， high and medium doses of Zhenwutang decreased the TCM syndrome score and E₂ content （P<0.05）， increased the T， T3， and T4 content （P<0.05）， improved the renal function （P<0.05）， alleviated the pathological changes in the renal tissue， increased CAT， T-AOC， and GSH （P<0.05）， reduced MDA （P<0.05）， and up-regulated the mRNA and protein levels of Nrf2， HO-1， GCLC， and GPX4 in the renal tissue （P<0.05）. ConclusionZhenwutang can improve the general state and renal function and reduce the oxidative damage and pathological changes in the renal tissue of db/db mice with spleen-kidney Yang deficiency by regulating the Nrf2/HO-1/GPX4 signaling pathway.

Yuhuanglian is one of the representative processed products to change the medicinal properties of Coptidis Rhizoma， which was first published in Hanshi Yitong. Its processing method is to mix Evodiae Fructus juice with Coptidis Rhizoma with stir-frying for drying， that is， Coptidis Rhizoma processed with Evodiae Fructus juice can reduce the bitterness and cold properties on the basis of retaining the effect of purging fire and detoxification， so that Yuhuanglian is cold but not stagnant， which can clear dampness-heat in Qifen， and is effective in treating the liver-qi invading stomach， vomiting and swallowing acid. As a representative variety of processing with medicine juice， Yuhuanglian is included in the 2020 edition of Chinese Pharmacopoeia and local processing standards， and its processing technology research and optimization has been attracting much attention. Modern studies have shown that Yuhuanglian not only contains berberine， jatrorrhizine， palmatine and other components， but also contains evodiamine， rutaecarpine， limonin and other components from Evodiae Fructus， which have anti-inflammatory， antibacterial， anti-tumor and other pharmacological activities. This paper collated and summarized the related research reports of Yuhuanglian in the past 20 years from the perspectives of processing history， efficacy and medicinal properties， quality evaluation and clinical application， and found that the processing methods and standards of Yuhuanglian were quite different in different provinces and cities， mainly involving the preparation and dosage of Evodiae Fructus juice and the criteria for the processing end point. In addition， the changes in the major components of Yuhuanglian before and after processing varied greatly among different studies， presumably related to the different processes and quality standards， this paper summarized the processing history， technology， pharmacodynamics， quality evaluation and clinical application of Yuhuanglian， in order to provide reference for improving its quality evaluation system.

ObjectiveTo investigate the antiviral effect of Menispermi Rhizoma total alkaloids and its relationship with the type Ⅰ interferon （IFN-Ⅰ） signaling pathway. MethodThe effects of Menispermi Rhizoma total alkaloids on the intracellular replication of influenza A virus （H1N1）， vesicular stomatitis virus （VSV）， and cerebral myocarditis virus （EMCV） were detected by fluorescent inverted microscope， flow cytometry， Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and Western blot. A mouse model infected with H1N1 was constructed， and the mice were divided into a control group， H1N1 model group， Menispermi Rhizoma total alkaloids groups （10， 20， 30 mg·kg^-1）， and oseltamivir group （40 mg·kg^-1）， so as to study the effects on the weight and survival rate of infected mice. Real-time PCR was used to detect the activation effect of Menispermi Rhizoma total alkaloids on the IFN-Ⅰ pathway in cells， and the relationship between the antiviral effect of Menispermi Rhizoma total alkaloids in IFNAR1 knockout A549 cells （IFNAR1^-/--A549） and IFN-Ⅰ pathway was detected. ResultCompared with the control group， the virus proliferated significantly in the model group （P<0.01）. Compared with the model group， Menispermi Rhizoma total alkaloids could significantly inhibit the replication of H1N1， VSV， and EMCV in vitro （P<0.01）， inhibit the weight loss of the mice infected with the H1N1 in vivo， and improve the survival rate of mice （P<0.05）. In addition， Menispermi Rhizoma total alkaloids activated the IFN-I pathway and relied on this pathway to exert the function of antiviral infection. ConclusionMenispermi Rhizoma total alkaloids exert antiviral effects in vivo and in vitro by activating the IFN-Ⅰ pathway.

ObjectiveAlthough expression of the TEAD1 protein in preadipocytes has been established, its function remains unclear. In this study, we sought to detect transcripts of TEAD1 in chicken and to examine the effects of this protein on the proliferation, migration, apoptosis, and differentiation of immortalized chicken preadipocyte cell lines (ICP1). MethodsThe full-length sequence of the TEAD1 gene was cloned and the two transcripts were subjected to bioinformatics analysis. The subcellsular localization of TEAD1 transcripts was determined based on indirect immunofluorescence. The effects of TEAD1 transcripts overexpression on the proliferation of ICP1 cells were examined by RT-qPCR, CCK-8, and EdU assays; the effects of TEAD1 transcripts on ICP1 cells migration were examined based on the scratch test; and the effects of TEAD1 transcripts overexpression on ICP1 cells apoptosis were analyzed using apoptosis-Hoechst staining and RT-qPCR. The expression of TEAD1 transcripts in different tissues, cells lines, and ICP1 at different periods of differentiation was analyzed by RT-qPCR. The effects of TEAD1 transcripts overexpression on lipid droplet accumulation and adipogenic-related gene expression in ICP1 cells were analyzed based on Oil Red O and BODIPY staining, RT-qPCR, Western blot, and dual-luciferase reporter gene assays. Finally, the content of triglyceride (TG) was measured in TEAD1 overexpressed ICP1 cells. ResultsThe full-length TEAD1 was cloned and two TEAD1 transcripts were identified. The TEAD1-V1 protein was found to be localized primarily in the cell nucleus, whereas the TEAD1-V2 protein is localized in the cell cytoplasm and nucleus. The overexpression of both TEAD1-V1 and TEAD1-V2 significantly inhibited the proliferation of ICP1 cells. Whereas the overexpression of TEAD1-V1 promoted ICP1 cell migration, the overexpression of TEAD1-V2 had no significant effects on ICP1 migration; the overexpression of both TEAD1-V1 and TEAD1-V2 significantly promoted the apoptosis of ICP1 cells. We found that the different transcripts of TEAD1 have similar expression pattern in different tissues and cells lines. During induced preadipocyte differentiation, the expression of these genes initially declined, although subsequently increased. Overexpression of TEAD1-V1 promoted a significant reduction in lipid droplet formation and inhibited C/EBPα expression during the differentiation of ICP1 cells (P<0.05). However, the overexpression of TEAD1-V2 had no significant effect on lipid droplet accumulation or the expression of adipogenic-related proteins (P>0.05). Overexpression of TEAD1-V1 significantly decreased triglyceride content in ICP1 cells (P<0.05), while overexpression of TEAD1-V2 had no effect on triglyceride content in ICP1 cells (P>0.05). ConclusionIn this study, for the first time, identified two TEAD1 transcripts. Overexpressed transcripts TEAD1-V1 and TEAD1-V2 both inhibited the proliferation of chicken preadipocytes and promoted apoptosis of chicken preadipocytes. TEAD1-V1 inhibited the differentiation of preadipocytes and promoted the migration of preadipocytes, while TEAD1-V2 had no effect on the differentiation and migration of preadipocytes.
