ABSTRACT
Liver failure (LF), as a clinical syndrome of severe hepatocyte damage and liver dysfunction, has become a major obstacle to human health due to the triple superposition of high mortality, high morbidity, and high medical resource depletion. It is of great significance to further study the core factors of the disease and supplementary treatment methods to improve the survival rate of patients with LF. The pathogenesis of LF is complex, and mitochondrion is one of the sensitive organelles in hepatocytes and the central link of intracellular energy metabolism. A large number of studies have shown that the structure and function of mitochondria in hepatocytes are changed in LF, and the abnormal structure and function of mitochondria play an important role in the process of LF disease. Among them, multiple factors such as mitochondrial respiratory chain disorder, mitochondrial DNA damage, mitochondrial permeability transition pore opening, mitochondrial quality control imbalance, and mitochondrial oxidative stress are intertwined, forming a complex and unified whole network, which becomes the key node affecting the progression of LF. In recent years, researchers have begun to study drugs that can regulate the function of liver mitochondria to prevent and treat LF. With the deepening of research, traditional Chinese medicine has made breakthroughs in the prevention and treatment of LF. Many studies have confirmed that traditional Chinese medicine can play a role in the prevention and treatment of LF by protecting mitochondrial function, which can be summarized as reducing liver cell damage, inhibiting liver cell death, and promoting liver cell regeneration, so as to effectively compensate for liver function and promote the recovery of liver parenchyma quality and function. This article summarized the structure and function of mitochondria, the relationship between LF and mitochondria, and the research on the intervention of mitochondrial function in the field of traditional Chinese medicine to prevent and treat LF, so as to provide certain ideas and references for the clinical treatment of LF with traditional Chinese medicine.
ABSTRACT
Objective: Prior research has shown mixed results regarding the effectiveness of combining donepezil and traditional Chinese medicine (TCM) to treat mild cognitive impairment (MCI). In light of this, our study aims to examine the efficacy and safety of this treatment approach for patients with MCI. Methods: We conducted a comprehensive search of various databases, including Medline (via PubMed), Cochrane, Embase, Web of Science, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wanfang Database from their inception to November 16, 2022. The selection of studies, risk of bias assessment, and data extraction were carried out independently by two authors. The statistical analysis was performed using STATA. Results: Our meta-analysis included a total of 35 studies with 2,833 patients, published between 2008 and 2022, with intervention durations ranging from 4 weeks to 12 months. However, most of the studies had a high risk of detection bias. Our findings indicated that the combination of donepezil and TCM significantly improved the Montreal Cognitive Assessment (MoCA) score (weighted mean difference [WMD] = 2.79, 95% confidence interval [CI]: 1.82 to 3.75) and the Barthel Index score (WMD = 9.20, 95% CI: 5.39 to 13.00) compared to donepezil alone. However, subgroup analyses showed that the MoCA score did not increase significantly in patients with MCI resulting from cerebrovascular disease (WMD = 1.47, 95% CI: -0.02 to 2.96). Conclusion: The combination of donepezil and TCM may have a more positive effect on cognitive function and activities of daily living in patients with MCI compared to the use of donepezil alone. However, due to the limited quality of the studies included in our analysis, these findings should be interpreted with caution.
ABSTRACT
OBJECTIVE@#To investigate the neuroprotective effect of electroacupuncture (EA) at "Quchi" (LI 11) and "Zusanli" (ST 36) in the rats with cerebral ischemic reperfusion and the potential mechanism of microglia pyroptosis.@*METHODS@#Sixty SD rats were randomly divided into a sham-operation group, a model group and an EA group, with 20 rats in each group. The Zea Longa method was employed to establish the rat model of the middle cerebral artery occlusion and reperfusion (MACO/R) in the left brain. In the EA group, since the 2nd day of modeling, EA was given at "Quchi" (LI 11) and "Zusanli" (ST 36) of right side with disperse-dense wave, 4 Hz/20 Hz in frequency and 0.2 mA in current intensity, 30 min each time, once a day for lasting 7 consecutive days. The reduction rate of cerebral blood flow was measured with laser Doppler flowmetry during operation. The neurological function of rats was observed using Zea Longa neurobehavioral score. The cerebral infarction volume was detected by TTC staining method. The microglia positive expression in the ischemic side of the cortex was detected with the immunofluorescence method. Under transmission electron microscope, the ultrastructure of cell in the ischemic cortex was observed. The mRNA expression levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), cysteinyl aspartate specific proteinase-1 (Caspase-1) and gasdermin D (GSDMD) in the ischemic cortex were detected using real-time PCR.@*RESULTS@#Compared with the sham-operation group, in the model group, the reduction rate of cerebral blood flow was increased during operation (P<0.001); Zea Longa neurobehavional score and the percentage of cerebral infarction volume were increased (P<0.001), the numbers of M1-type microglia marked by CD68+ and M2-type microglia marked by TMEM119+ were elevated in the ischemic cortex (P<0.001), the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was increased (P<0.001, P<0.01); the cytomembrane structure was destroyed, with more cell membrane pores formed in the ischemic cortex. Compared with the model group, after intervention, Zea Longa neurobehavioral score and the percentage of cerebral infarction volume were reduced (P<0.05), the number of M1-type microglia marked by CD68+ was reduced (P<0.05) and the number of M2-type microglia marked by TMEM119+ was increased (P<0.05); and the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was decreased (P<0.01, P<0.05) in the EA group. Even though the cytomembrane structure was incomplete, there were less membrane pores presented in the ischemic cortex in the EA group after intervention.@*CONCLUSION@#The intervention with EA attenuates the neurological dysfunction and reduces the volume of cerebral infarction in the rats with cerebral ischemic reperfusion. The underlying mechanism is related to the inhibition of microglia pyroptosis through modulating NLRP3/Caspase-1/GSDMD axis.

ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.

The name, origin, place of origin, medicinal parts, harvesting and processing of lotus are verified by consulting ancient Chinese herbal medicines and medical books, combined with modern literature, providing a basis for the development of famous classical formulas containing lotus. According to textual research, the original base of lotus is Nelumbo nucifera since ancient times, rhizome (Nelumbinis Rhizomatis Nodus), leaf (Nelumbinis Folium), seed (Nelumbinis Semen), embryo (Nelumbinis Plumula), receptacle (Nelumbinis Receptaculum), stamen (Nelumbinis Stamen) and other medicinal parts of N. nucifera can be used as medicine and have different clinical effects. Nelumbinis Semen was originally produced in Henan, and then gradually expanded to Jiangnan. Today, it can be cultivated and planted throughout the country, with Fujian, Hunan, and Jiangxi as the authentic production areas. After combing the medicinal parts of N. nucifera and the historical evolution of its processing, it is suggested that the dried and mature fruits of N. nucifera taking in autumn and removing the shell and Nelumbinis Plumula should be used in Qingxin Lianziyin. Nelumbinis Folium in Erdongtang should be harvested in summer and autumn, and the raw products was used as medicine and processed in accordance with the provision of the 2020 edition of Chinese Pharmacopoeia.
ABSTRACT
Based on various ancient documents such as materia medica, prescription books, classics and history, combined with relevant research materials in modern times, this paper made a textual research on the name, origin, geoherbalism, harvesting time, processing methods of Chuanxiong Rhizoma, which provides a basis for the development of famous classical formulas containing this herb. According to the textual research, the original name of Chuanxiong is Xiongqiong (芎䓖), which was first recorded in Shennong Bencaojing , there are many aliases and trade names in the past dynasties. Since the Song dynasty, doctors all take Xiongqiong produced in Sichuan as the best medicine, so they take Chuanxiong as the rectification of name. In the early stage, the origin of Chuanxiong Rhizoma was relatively complicated, and the main origin was Ligusticum chuanxiong, which was a cultivated and domesticated species of Ligusticum. However, wild related plants of Ligusticum are still used as medicine. After the Ming dynasty, new cultivated varieties appeared in various places, such as Jiangxi L. sinense cv. Fuxiong, which gradually turned to self-production and self-marketing after the Republic of China. After several changes in the authentic producing area of Chuanxiong Rhizoma, Tianshui in Gansu province was highly praised in the Tang dynasty, and Dujiangyan in Sichuan province was the best place in the Song dynasty and later dynasties. Chuanxiong Rhizoma has been widely used in the past dynasties as raw products, and it has also been processed with excipients. For example, wine-processed products can enhance the effect of promoting blood circulation, promoting Qi circulation and relieving pain. There are other processing methods such as stir-frying and vinegar processing. Chuanxiong Rhizoma in the famous classical formulas can be selected according to this research conclusion.
ABSTRACT
This paper made a systematic textual research on the historical evolution and changes of the name, origin, producing area, harvesting and processing methods of Jujubae Fructus used in famous classical formulas by referring to the ancient literature, so as to provide a basis for the sampling and research of the formulas containing the medicinal materials. According to textual research, there are many names of Jujubae Fructus, most of which are named by characters or producing areas, which are called Dazao. Ziziphus jujuba has always been the mainstream variety in all dynasties, and Z. jujuba var. inemmis has also been used. Considering that the differences between the two are not obvious, we can use Z. jujuba and Z. jujuba var. inemmis as the origins of Dazao. The germplasm resources of Jujubae Fructus are rich, which are distributed all over the country. Qingzhou (now Shandong), Jinzhou (now Shanxi) Jiangzhou (now Shanxi), Puzhou (now Shanxi) have been recorded as authentic producing areas of Jujubae Fructus in the past dynasties, especially in Shandong. At the beginning of the 21st century, the planting of Jujubae Fructus in Xinjiang gradually developed, and now has a high market recognition, becoming an emerging production area of high-quality samples. Harvest period of Jujubae Fructus is mostly August in the past dynasties, and this is basically the same as today. The main processing method is simple cleansing and drying. Through textual research, it is suggested that Jujubae Fructus in famous classical formulas should be mainly from Shandong, Shanxi and other traditional high-quality producing areas, the processing method should follow the 2020 edition of Chinese Pharmacopoeia for simple cleansing and drying.
ABSTRACT
Based on the ancient literature of all dynasties, this article makes a systematic textual research on the name, origin, producing area, quality, harvesting and processing of Magnoliae Officinalis Cortex used in the famous classical formulas, and clarifies its information of each link in different historical periods, so as to provide a reference and basis for the development and utilization of the related formulas. The results showed that the main varieties of Magnoliae Officinalis Cortex were Magnolia officinalis or M. officinalis var. biloba. The main production areas are Hubei, Sichuan, Chongqing and other places, forming the famous authentic medicine. The processing methods of the past dynasties are mainly cleansing and processing with ginger. In the formulas clearly marked with ginger processing, ginger-processed products is suggested to choose. If not clearly marked, raw or ginger-processed products can be used as needed.
ABSTRACT
Through consulting the ancient herbal medicine, prescription books and medical books, combined with modern relevant literature, standards and other information, this paper made a textual research on the name, origin, producing areas, harvesting and processing methods of Astragali Radix according to different historical development periods, providing a basis for the development of famous classical formulas containing Astragali Radix. According to the textual research, the original name of Astragali Radix is Huangqi, and "Qi" originally refers to the medicinal material Zhimu. Some people began to mistake it for Huangqi in the Ming dynasty, and then gradually used Astragali Radix as a medicinal material. The mainstream basis of Astragali Radix can be determined as the dried roots of Astragalus membranaceus var. mongholicus or A. membranaceus. In different historical periods, A. floridus, A. chrysopterus, A. emestii and other plants of Astragalus or even non-Astragalus were used as local Astragali Radix. The earliest production areas of Astragali Radix were Sichuan, Shaanxi, and Gansu, and then gradually expanded to the northeast. Since the Song dynasty, Mianqi in Shanxi province has been regarded as the genuine variety. In the Qing dynasty, besides Shanxi province, Inner Mongolia was also regarded as a genuine place. In the Republic of China, Huangqi produced in northeast China was praised highly. It is mainly produced in Shanxi, Inner Mongolia, Gansu, northeast and other provinces. The main commodity is cultivated products, and the quality of wild imitation cultivation in Datong and Xinzhou is better than other places. There are many processing methods of Huangqi recorded in the materia medica and prescription books, most of which are raw products, and honey processing is the mainstream of processed products. Based on the current situation of resource cultivation and production, 11 famous classical formulas in The Catalogue of Ancient Famous Classical Formulas (The First Batch) containing Huangqi suggested that all use A. membranaceus var. mongholicus, especially those from Datong and Xinzhou in Shanxi Province. In addition to honey processing of Qingxin Lianziyin, it is suggested to use raw products for other formulas.
ABSTRACT
ObjectiveTo observe the therapeutic effect of Radix Paeoniae Rubra-Radix Aconiti Lateralis on acute-on-chronic liver failure (ACLF) rats and its effect on M1/M2 macrophage polarization. MethodMale SD rats were randomly divided into normal group, model group, positive group (lactulose, 1.8 g·kg-1) and traditional Chinese medicine (TCM) group (Radix Paeoniae Rubra-Radix Aconiti Lateralis, 5.85 g·kg-1), six in each group. The ACLF rat model was established by subcutaneous and tail vein injection of bovine serum albumin combined with intraperitoneal injection of D-galactosamine+lipopolysaccharide. Then the modeled rats were intervened with corresponding drugs for one week. The normal group and model group were given the same dose of distilled water. The histopathological changes of liver tissue were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expression levels of CD86, inducible nitric oxide synthase (iNOS), CD206 and arginase 1 (Arg1) were detected by real-time polymerase chain reaction (Real-time PCR), Western blot and immunohistochemistry. ResultCompared with the conditions in the normal group, pseudolobule formation in liver tissue and morphological changes and necrosis of hepatocytes were observed in ACLF rats, accompanied by a large number of inflammatory cell infiltration. Moreover, the mRNA and protein expression levels of CD86, iNOS were up-regulated(P<0.01). Compared with the model group, the treatment groups had improved necrosis and inflammatory infiltration of hepatocytes, down-regulated mRNA and protein expression of CD86 and iNOS (P<0.01) and up-regulated mRNA and protein expression of CD206 and Arg1 (P<0.05, P<0.01), with the up regulation in the TCM group better than that in the positive group. ConclusionACLF rats had unbalanced M1/M2 macrophage polarization, and the imbalance shifted towards M1. Radix Paeoniae Rubra-Radix Aconiti Lateralis inhibited the activation of M1 macrophages and reduced the inflammatory response of liver failure by promoting the polarization of liver macrophages towards M2.
ABSTRACT
Objective:To investigate the effect of fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space in differentiated thyroid cancer surgery.Methods:Sixty patients with differentiated thyroid cancer who received treatment in Ningbo Hospital of Traditional Chinese Medicine from January 2017 to April 2020 were included in this study. They were randomly assigned to receive either fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space (observation group, n = 30) or routine surgery + inferior thyroid artery exposure of recurrent laryngeal nerve (control group, n = 30). Operative time, the volume of intraoperative blood loss, and the number of lymph node dissected were compared between the two groups. Parathyroid hormone (PTH) and blood calcium (Ca 2+) concentrations in the two groups were determined. The adverse reactions such as recurrent laryngeal nerve and parathyroid injury were observed in each group. Results:Operative time, the volume of intraoperative blood loss, and the number of lymph node dissected in the observation group were (71.28 ± 10.08) minutes, (16.69 ± 4.65) mL, and (4.78 ± 1.26), respectively, which were significantly different from those in the control group [(69.27 ± 11.89) minutes, (17.14 ± 4.52) mL, (4.76 ± 1.22), t = 0.706, 0.380, 0.062, all P > 0.05]. Before surgery, there were no significant differences in PTH and Ca 2+ concentrations between the two groups [PTH: (50.24 ± 11.21) g/L vs. (50.21 ± 11.19) g/L; Ca 2+: (2.18 ± 0.08) mmol/L vs. (2.17 ± 0.09) mmol/L, t = 0.010, 0.454, both P > 0.05]. After surgery, PTH and Ca 2+ concentrations in the observation group were significantly higher than those in the control group [PTH: [(31.44 ± 6.09) g/L vs. (16.57 ± 2.35) g/L; Ca 2+: (2.07 ± 0.10) mmol/L vs. (1.23 ± 0.12) mmol/L, t = 12.477, 29.454, both P < 0.01]. Total incidence of adverse reactions in the observation group was significantly lower than that in the control group [10.00% (3/30) vs. 46.67% (14/30), χ2 = 9.931, P < 0.01). Conclusion:Application of fine anatomy combined with exposure of recurrent laryngeal nerve in cricothyroid space in differentiated thyroid cancer surgery is highly effective in the clinic. Accurate identification of recurrent laryngeal nerve in cricothyroid space is helpful to preserve the parathyroid gland and blood supply in situ, leads to a small range of changes in PTH and Ca 2+ concentrations, reduces postoperative complications, so as to protect the recurrent laryngeal nerve and parathyroid gland and thereby promote postoperative recovery.
ABSTRACT
Objective:To discuss the surgical strategies for anteromedial tibial plateau compression fracture complicated with posterolateral corner injury.Methods:From 2015 January to 2020 July, 18 patients with anteromedial tibial plateau compression fracture complicated with posterolateral corner injury were admitted to Department Ⅲ of Orthopaedics, Zhongshan Hospital of Traditional Chinese Medicine. They were 11 males and 7 females, aged from 28 to 57 years (average, 38.6 years). By the CT three-column theory, all their fractures were medial column ones; by the Fanelli classification, there were 5 cases of type B and 13 cases of type C. Seventeen patients with fresh fracture were treated with arthroscopic ligament reconstruction and meniscus repair followed by primary reduction and fixation of tibial plateau fracture. The one patient with obsolete injury was treated with high tibial osteotomy around the knee joint and reconstruction of the anterior cruciate ligament. Recorded were the patients' fracture healing time, knee Lysholm score, joint range of motion and complications.Results:The 17 patients with fresh injuries were followed up for 12 to 24 months (average, 18.4 months). Their fracture healing time ranged from 12 to 24 weeks (average, 17.7 weeks). By one year after surgery, their knee extension reached 0° and their knee flexion from 120° to 135° (average, 131.9°); their knee Lysholm scores ranged from 88 to 95 points (average, 91.2 points). The one patient with old injuries was followed up for 18 months, with fracture healing time of 18 weeks, knee range of motion from 0° to 120° and knee Lysholm score of 86 points by one year after operation. None of the patients reported such complications as neurovascular injury, wound infection, internal fixation failure or nonunion.Conclusion:For anteromedial tibial plateau compression fracture complicated with posterolateral corner injury, primary repair and reconstruction can restore knee joint stability, leading to fine therapeutic outcomes.
ABSTRACT
OBJECTIVE@#To investigate the potential mechanisms of electroacupuncture (EA) to prevent ischemic stroke.@*METHODS@#The method of middle cerebral artery occlusion (MCAO) was employed to establish a rat model of ischemic stroke. Seventy-eight Sprague-Dawley rats were divided into the sham group, MCAO + EA control (EC) group, and MCAO + EA (EA) group according to a random number table (n=26 per group). EA was applied to the acupoints of Baihui (DU 20) and Shenting (DU 24) 5 min and 6 h, respectively after the onset of MCAO. Rats in the sham and EC groups received only light isoflurane anesthesia for 30 min after MCAO. The neuroprotective effects of EA were evaluated by rota-rod test, neurological deficit scores and infarct volumes. Additionally, Nissl staining and immunostaining were performed to examine brain damage, rod formation, cellular apoptosis, and neuronal loss induced by ischemia. The activities of caspase-3, and expression levels of cofilin and p-cofilin in mitochondria and cytoplasm after ischemic injury were determined by Western blot.@*RESULTS@#Compared with the EC group, EA significantly improved neuromotor function and cognitive ability after ischemic stroke (P<0.05 or P<0.01). Therapeutic use of EA also resulted in a significant decrease of cofilin rod formation and microtubule-associated protein-2 (MAP2) degradation in the cortical penumbra area compared with the EC rats (P<0.01). Furthermore, Western blot analysis showed that EA stimulation significantly inhibited mitochondrial translocation of cofilin and caspase-3 cleavage (P<0.05 or P<0.01). Additionally, brain damage (infarct volume and neuropathy), cellular apoptosis and neuronal loss induced by ischemia were remarkably suppressed by EA in the cortical penumbra of rats (P<0.05 or P<0.01).@*CONCLUSION@#EA treatment after ischemic stroke may attenuate ischemic brain injury and cellular apoptosis through the regulation of mitochondrial translocation of cofilin, a novel mechanism of EA therapy.
ABSTRACT
Biofilm producing clinical bacterial isolates were isolated from periodontal and dental caries samples and identified as, Lactobacillus acidophilus, Streptococcus sanguis, S. salivarius, S. mutansand Staphylococcus aureus. Among the identified bacterial species, S. aureus and S. mutansshowed strong biofilm producing capacity. The other isolated bacteria, Streptococcus sanguis, S. salivarius showed moderate biofilm formation. These pathogens were subjected for the production of extracellular polysaccharides (EPS) in nutrient broth medium and the strain S. aureus synthesized more amounts of EPS (610 ± 11.2 µg/ml) than S. sanguis (480 ± 5.8 µg/ml).EPS production was found to be less in S. salivarius (52 ± 3.8 µg/ml).The solvent extract of A. sativum bulb showed the phytochemicals such as, carbohydrate, total protein, alkaloids, saponins, flavonoids, tannins and sterioids. The solvent extract of A. sativum bulb showed wide ranges of activity against the selected dental pathogens. The difference in antibacterial activity of the solvent extract revealed differences in solubility of phytochemicals in organic solvents. Ethanol extract was highly active againstS. aureus (25 ± 2 mm). The Minimum Inhibitory Concentration (MIC) of crude garlic bulb varied widely and this clearly showed that bacteria exhibits different level of susceptibility to secondary metabolites. MIC value ranged between 20 ± 2 mg/ml and 120 ± 6 mg/ml and Minimum Bactericidal Concentration (MBC) value ranged from 60 ± 5 mg/l to 215 ± 7 mg/ml. To conclude, A. sativum bulb can be effectively used to treat periodontal and dental caries infections.
ABSTRACT
Endophytic fungi can produce beneficial active components during symbiosis with host plants. Fifteen purified endophytic fungal strains were isolated and screened from root, stem, leaf, and fruit of the Chinese medicine food homologous plant Siraitia grosvenorii. These strains were fermented, and then the fermented solution was extracted using acetonitrile. The extracts were analyzed by high performance liquid chromatography (HPLC) and mass spectrum (MS), using standard mogroside V as control. The results showed that strain LHG-F5 and strain LHG-L4 could produce mogroside V with output of 3.814 µg/mL and 2.675 µg/mL, respectively. By morphological observation together with similarity of internal transcribed spacer (ITS) sequence by Clustan X method, LHG-F5 and LHG-L4 were classified as Diaporthe angelica and Fusarium solani, respectively.

Objective::To study the effect of warming and heat-clearing method (Wenyang Jiedu Huayu decoction) on the expressions of Forkhead box P3 (FoxP3), Retinoic acid-related orphan receptor gamma t (ROR-γt) in colon tissue of mice with acute-on-chronic liver failure (ACLF), in order to explore the possible regulatory mechanism on intestinal endotoxemia (IETM) in liver failure mice. Method::The 130 SD rats were randomly divided into normal group (10 rats) and model group (120 rats). The ACLF mice model was established through the subcutaneous injection with bovine serum albumin and the intraperitoneal injection with D-galactosamine(D-Gal) and lipopolysaccharide (LPS). The model mice were randomly divided into model group, heat-clearing group (Yinchenhao decoction, 6.68 g·kg-1), warming group (Yinchen Zhufu decoction, 7.09 g·kg-1) and warming and heat-clearing group (Wenyang Jiedu Huayu decoction, 19.53 g·kg-1). The normal group and the model group were given distilled water by gastric lavage, while the other groups were given equal volume of corresponding Chinese herbal medicines for a week. The value of each index at 1, 12 and 24 h was measured. The ratio of Treg/Th17 cell in peripheral blood were detected and calculated by flow cytometry. Real-time fluorescence quantitative PCR (Real-time PCR) was used to detect the expressions of FoxP3 and ROR-γt in colon tissues of mice at different time points. In situ hybridization and immunohistochemistry were used to observe the expressions of FoxP3 and ROR-γt genes and proteins. Result::Compared with normal group, the ratio of Treg/Th17 in the model group decreased significantly at each time point (P<0.01). Compared with the model group, the Treg/Th17 ratio increased only in the warming and heat-clearing method group (P<0.05). Compared with normal group, the expression of ROR-γt in the model group was significantly higher (P<0.01), and the expression of ROR-γt in the model group was higher than FoxP3.Compared with the model group, the expressions of FoxP3 and ROR-γt mRNA in the heat-clearing group and the warming group decreased at each time point (P<0.05), and the expressions of FoxP3 and ROR-γt in the warming and heat-clearing method group decreased significantly (P<0.01). The expressions of FoxP3 and ROR-γt mRNA in warming and heat-clearing group decreased compared with those in the warming group and heat-clearing group (P<0.05). Conclusion::The mechanism of the warming and heat-clearing method on IETM in liver failure may be related to the regulation of FoxP3 and ROR-γt expressions.
ABSTRACT
Objective::To detect the expression levels of peripheral blood Treg/Th17 cells and related cytokines in patients with Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) with different traditional Chinese medicine (TCM) syndrome " Yanghuang-Yinyanghuang-Yinhuang" , in order to explore the cellular immunological characteristics of different TCM syndromes of liver failure. Method::The 32 cases of patients with HBV-ACLF in early, middle and late stages in line with the " Yanghuang-Yinyanghuang-Yinhuang" TCM syndrome grouping were selected. Flow cytometry was used to detect the frequency expression of Treg/Th17 cells in peripheral blood. The expression levels of interleukin-10(IL-10), transforming growth factor-β(TGF-β), interleukin-17A(IL-17A), tumor necrosis factor-α(TNF-α) and interleukin-23(IL-23) were detected by cytometric bead array (CBA). The expressions of transcription factor forkhead box P3(FoxP3) and retinoid-related orphan nuclear receptor-γt(ROR-γt) mRNA were detected by Real-time PCR. The SPSS 20.0 software was applied in data statistics and processing to analyze the expression characteristics of Treg/Th17 cells and related cytokines in patients with different TCM syndrome types of HBV-ACLF. Result::The patients with HBV-ACLF Yanghuang syndrome were mainly distributed in the early stage of liver failure, those with Yinyanghuang syndrome were mainly distributed in the middle stage, and those with Yinhuang syndrome were distributed in the late stage. From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the frequency of Treg and Th17 cells gradually increased, and the differences among the groups were statistically significant (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, Treg cytokines IL-10, TGF-β gradually increased, and the differences among the groups were statistically significant (P<0.05). Th17 cytokines IL-17A, TNF-α, IL-23 gradually increased, of which IL-17A were differences between Yanghuang syndrome and the Yinyanghuang syndrome, as well as Yanghuang syndrome and Yinhuang syndrome (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the expression of FoxP3 was gradually decreased, while that of ROR-γt was gradually increased, and the differences among the groups were statistically significant (P<0.01). Conclusion::There is a certain correlation between the different course of early, middle and late stages of HBV-ACLF and the distribution of TCM syndromes. The frequency of Treg and Th17 cells and the correlation of IL-17A, TGF-β and IL-10 with TCM syndrome differentiation are related, suggesting that Treg and Th17 cells have a certain reference value for the diagnosis of patients with HBV-ACLF and the syndrome differentiation of TCM syndromes.
ABSTRACT
Objective::Through the retrospective study of Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) patients, the clinical features and the characteristics of traditional Chinese medicine (TCM) syndrome distribution of HBV-ACLF complicated with bacterial infection were preliminarily expounded, so as to provide the corresponding theoretical basis for the diagnosis and treatment of HBV-ACLF secondary bacterial infection. Method::A unified data collection form for patients with slow plus acute liver failure was designed by the retrospective epidemiological investigation method. The clinical data of 307 patients with HBV-ACLF who were hospitalized at the Hepatology Institute of the First Affiliated Hospital of Hunan University of Chinese Medicine were collected in strict accordance with the inclusion and exclusion standards, and the main symptoms and the TCM symptoms were screened. Then, according to whether or not there was a bacterial infection, the patients were divided into a combined bacterial infection group and a non-combined bacterial infection group. The distribution characteristics of the main symptoms and the TCM symptoms in two groups were compared, and the distribution characteristics of TCM symptoms of HBV-ACLF with bacterial infection were obtained. Result::Compared with patients with uncombined bacterial infection, patients with combined bacterial infection had significantly increased abdominal distension, puffiness, purple and dark tongue color, abdominal varicose tendons, subcutaneous stasis spots, and tooth marks on the side of the tongue. Compared with patients with combined bacterial infections, patients with uncombined bacterial infections mainly showed bright yellow head, yellow tongue coating, and significantly increased dry mouth (P<0.05, P<0.01). The main symptoms of patients with combined bacterial infections was the combination of syndrome (93.6%), and more spleen deficiency syndrome (81.6%), patients with uncombined bacterial infections mainly suffered from a single syndrome (53.5%), which was mostly damp-heat syndrome (51.9%), patients of concurrent syndrome with combined bacterial infections mostly suffered from false and real syndrome (94.4%), which was significantly higher than those with uncombined bacterial infections (58.9%). Conclusion::The patients with HBV-ACLF without bacterial infection mainly suffered from damp-heat symptoms and signs. With the combination of bacterial infection, the symptoms and signs of spleen deficiency and blood stasis gradually worsened. HBV-ACLF patients with bacterial infection mainly suffered from spleen deficiency and blood stasis, while patients with unincorporated bacterial infection mainly suffered from the single damp-heat symptoms and signs.
