Pathogenesis and Differentiated Treatment Strategies of Childhood Tic Disorders Based on WANG Xugao's “Thirty Methods of Treating the Liver” / 中医杂志

Based on WANG Xugao's “thirty methods of treating the liver”， it is believed that the occurrence and development of childhood tic disorders follow the dynamic progression from liver qi disease to liver fire disease and then liver wind disease. The basic pathogenesis of three stages are characterized by binding constraint of liver qi， liver fire hyperactivity， and internal stirring of liver wind. Moreover， liver-blood deficiency and stagnation， and malnutrition of liver yin as the main point in terms of the imbalance of liver qi， blood， yin， and yang should be considered， as well as the imbalance relationship of the five zang organs such as the involvement of other organs and the gradually reach of the other organs. Guided by the principles of “thirty methods of treating the liver”， the treatment of tic disorders in liver qi stage should focus on soothing the liver and rectifying qi， soothing the liver and unblocking the collaterals， using Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散）. The treatment of tic disorders in liver fire stage involves clearing， draining and resolving liver heat， using Longdan Xiegan Decoction （龙胆泻肝汤）， Xieqing Pill （泻青丸）， Danggui Longhui Pill （当归龙荟丸）， and Huagan Decoction （化肝煎）. The treatment of tic disorders in liver wind stage involves extinguishing wind and subduing yang， using Lingjiao Gouteng Decoction （羚角钩藤汤） and Liuwei Dihuang Pill （六味地黄丸）. Throughout the treatment process， attention should be paid to harmonizing the liver's qi， blood， yin， and yang， as well as addressing the pathology of other organs.

Medicated Serum of Bupleuri Radix Regulates HFL1 Apoptosis and Fibroblast-myofibroblast Transition via Smad3/Rheb Axis / 中国实验方剂学杂志

ObjectiveTransforming growth factor-β1 （TGF-β1） was used to stimulate human fetal lung fibroblast 1 （HFL1） for simulating the pathological process of idiopathic pulmonary fibrosis （IPF） and thereby the effects and mechanism of medicated serum of Bupleuri Radix against IPF were investigated. MethodTGF-β1 （10 μg·L-1） was employed to stimulate HFL1， and cells were treated with medicated serum of Bupleuri Radix （5%， 10%， 15%， 20%） for 24 h. Then cell proliferation rate was determined with cell counting kit-8 （CCK-8）. Subsequently， cells were classified into the control group （20% blank serum）， TGF-β1 group （20% blank serum and 10 μg·L-1 TGF-β1）， TGF-β1 + medicated serum of Bupleuri Radix group （5% blank serum， 15% medicated serum， and 10 μg·L-1 TGF-β1）， and TGF-β1 + SIS3 group （3 μmol·L-1 SIS3， 20% blank serum， 10 μg·L-1 TGF-β1）. Based on in situ end labeling （TUNEL） staining， the apoptosis rate was examined， and mRNA expression of apoptosis-related proteins B-cell lymphoma 2 （Bcl-2）， Bcl-2 associated X protein （Bax） and myofibroblast marker α-smooth muscle actin （α-SMA） was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The protein expression of α-SMA， Ras homolog enriched in brain （Rheb）， and phosphorylated （p）-Smad3 was determined by immunofluorescence. Expression of Rheb， p-Smad3， and Smad3 was examined by Western blot. ResultThe cell proliferation rate of TGF-β1 group increased compared with that of the control group （P<0.05）. The cell proliferation rate of TGF+15% medicated serum of Bupleuri Radix group and TGF+20% medicated serum of Bupleuri Radix group decreased compared with that of the TGF-β1 group （P<0.01）. Compared with the control group， TGF-β1 group showed decrease in apoptosis rate， increase in mRNA expression of Bcl-2 and α-SMA， reduction in Bax mRNA expression， and rise of α-SMA and Rheb protein expression and p-Smad3 level （P<0.05）. Compared with TGF-β1 group， TGF-β1 + medicated serum of Bupleuri Radix group and TGF-β1 + SIS3 group demonstrated high apoptosis rate， low Bcl-2 and α-SMA mRNA expression， high Bax mRNA expression， and low α-SMA and Rheb protein expression and p-Smad3 level （P<0.05）. ConclusionMedicated serum of Bupleuri Radix can inhibit TGF-β1-induced HFL1 proliferation and fibroblast-myofibroblast transition and promote fibroblast apoptosis by regulating the Smad3/Rheb axis.

Some thoughts on the research of mesenchymal stem cell exosomes and wound microenvironment / 中华烧伤杂志

Since researchers have found that the conditioned medium and exosomes of mesenchymal stem cells (MSCs) had the biological effects equivalent to those of MSCs, MSC exosomes (MSC-Exos), the representative product of MSCs' paracrine effect, have become the research focus of the "cell-free" therapy of MSCs. However, most researchers currently use conventional culture condition to culture MSCs and then isolate exosomes for the treatment of wound or other diseases. Theoretically, the paracrine effect of MSCs is directly associated with the pathological condition of the wound (disease) microenvironment or in vitro culture condition, and their paracrine components and biological effects may be altered with the changes of the wound (disease) microenvironment or in vitro culture condition. Thus, the feasibility of using traditional culture condition to culture MSCs for exosome extraction for the treatment of different diseases without considering the actual situation of the disease to be treated needs further discussion. Therefore, the author suggests that the research of MSC-Exos should consider the microenvironment of the wound (disease) to be treated. as much as possible, otherwise the extracted MSC-Exos may not be "accurate" or may not really achieve the treatment effect of MSCs. In this article, we summarized some thoughts of the author and problems related to the researches about MSC-Exos and wound microenvironment, and hoped to discuss with researchers.

Discussion on the Pathogenesis and Treatment of Sjögren's Syndrome Based on YE Gui's Theory of “Upper Dryness Treats Qi and Lower Dryness Treats Blood” / 中医杂志

The pathogenesis of Sjögren's syndrome （SS） was considered to involve external dryness， internal injured essence and blood， yin-deficiency endowment， and abnormal emotion and spirit， and it was believed that SS has the characteristics of dryness and impassability， and the pathogenesis of deficiency-excess in complexity. According to the theory “upper dryness treats qi， and lower dryness treats blood” in YE Gui's monograph “Medical Records for Clinical Guidance”， the dryness was divided into upper dryness and lower dryness syndromes to be differentiated and treated. When treating dryness syndrome， the patient should follow the characteristics of the five zang organs， using soft and cool medicines， avoiding warm and dry medicines， and valuing the animal products. The upper dryness could be treated with Sangxiang Decoction （桑杏汤） to clear the qi and moisten the dryness， Qiaohe Decoction （翘荷汤） to clear the upper with pungent-cool， and Shashen Maidong Decoction （沙参麦冬汤） to nourish yin and promote the production of body fluid. The lower dryness could be treated with Fumai Decoction （复脉汤） to enrich and nourish the five kinds of fluid. Liuwei Dihuang Pill （六味地黄丸） to nourish the kidneys and supplement essence， and Wuren Pill （五仁丸） to moisten the dryness and nourish the blood， which provided a new way of thinking for differentiation of the dryness syndrome.

Research progress of histidine-based tumor-targeting drug delivery systems / 药学学报

As a basic amino acid, histidine has a pKa close to the acidity of the tumor microenvironment, thus the charge and solubility of histidine are able to vary as the pH changes. Under a neutral environment, histidine is not charged and exhibits hydrophobic properties, while it can be protonated and becomes hydrophilic when exposed to mildly acidic pH, such as tumor microenvironment. Therefore, histidine is widely used in the design of drug delivery systems to target the mildly acidic pH of tumor microenvironment. This article reviews the recent progresses of histidine-based tumor-targeting drug delivery systems, and summarizes the principles on promoting internalization and tuning drug release by taking advantage of histidine. Finally, we point out the common issues on histidine application and illustrate its future prospects.

Progress on identification and management of Parkinson′s disease-related fatigue / 中华神经科杂志

Fatigue is one of the most common and disabling symptoms of Parkinson′s disease (PD), which has an important impact on the quality of life. Due to the lack of a strict and unified definition and classification of PD-related fatigue, as well as a clear quantitative standard, clinical studies on fatigue in PD have drawn different conclusions, making fatigue research challenging. Normative studies in this area have been complemented by the publication of the 2016 expert consensus on diagnostic criteria for PD associated fatigue. In this paper, the incidence, influencing factors, clinical evaluation measures and treatment of PD-related fatigue were reviewed to provide the latest information for clinical identification and management of PD-related fatigue patients.

Hemodynamic Analysis of Redissection after Endovascular Repair for One Stanford Type B Aortic Dissection Case / 医用生物力学

Objective Based on hemodynamic analysis, to investigate the cause of distal re-entry tear in Stanford type B aortic dissection after thoracic endovascular aortic repair (TEVAR).Methods A patient with type B aortic dissection was reexamined regularly with computed tomography angiography (CTA) at 1st month, 6th month, 12th month and 24th month after TEVAR. Based on the CTA images in each period, three-dimensional (3D) aorta models were reconstructed to perform morphological analysis and hemodynamic simulation.Results Compared with the diameter at 1st month after TEVAR, the diameter of true lumen at 12 months after TEVAR increased by 1.8 times and the global distortion of aorta increased by 16.67%. At postoperative 1st, 6th and 12th month, the maximum blood velocities at the new entry tear in systole were 69.6%, 33.7% and 92.1% higher than the average ones at distal landing zone, and the maximum wall shear stresses (WSSs) were 2.52, 2.32 and 3.52 times of the average WSSs respectively. In addition, the maximum time-averaged WSS (TAWSS) at 1st, 6th and 12th month after TEVAR were 1.88, 2.53 and 3.62 times of the mean TAWSS respectively.ConclusionsThe morphology of the aorta remodeled after TEVAR, and a sudden change in the diameter of true lumen occurred at distal anchoring zone and continued to increase. As a result, the blood flow velocity in this area accelerated, and the intima was continuously exposed to high WSS, leading to the redissection.

Clinical application effects of two longitudes three transverses method in perforator location of thoracodorsal artery perforator flap and deep wound repair / 中华烧伤杂志

Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Differences in the chemical composition of Dendrobium officinale Kimura et Migo and Dendrobium crepidatum Lindl based on UPLC-Q-TOF-MS/MS and metabolomics / 药学学报

italic>Dendrobium officinale Kimura et Migo is a rare Chinese herbal medicine, while Dendrobium crepidatum Lindl is a local medicine in Yunnan, both of which have the function of nourishing yin and stomach. To reveal the differences in chemical composition between the two species, ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) was used to analyze the chemical composition of stems and leaves of D. officinale and D. crepidatum. Principal component analysis (PCA) and partial least squares discriminant analysis (OPLS-DA) were used to determine the differences in metabolites between species and parts of Dendrobium. Fifty-eight chemical compounds were identified in the two species. Analysis indicated that the side ring of alkaloids connected with nitrogen was readily cleaved during analysis. The results of PCA analysis showed that the stems and leaves of D. officinale and D. crepidatum could be easily differentiated, and the chemical constituents of D. officinale and D. crepidatum were significantly different. OPLS-DA analysis showed that there were 16 metabolite differences between the stems and 22 differences in metabolites between the leaves of D. officinale and D. crepidatum. The main metabolite differences in components between the two Dendrobium species were dendrocrepidine B, dendrocrepidine C and dendrocrepine. There were 14 differences in metabolites between the stems and leaves of D. crepidatum. In conclusion, the chemical compositions of D. officinale and D. crepidatum are quite different; the small molecular compounds of D. officinale are mainly terpenoids and flavonoids, and the content of alkaloids is low. There is no significant difference between stem and leaf. In contrast, D. crepidatum is mainly composed of alkaloids and terpenoids, with crepidamine and dendrocrepine as its unique components, and there are great differences in the components between stems and leaves. This study provides a theoretical basis for the development and utilization of Dendrobium resources.

Analysis on Role of mTORC1/4E-BP1 Axis in Idiopathic Pulmonary Fibrosis and Research Progress of Bupleuri Radix on Its Intervention / 中国实验方剂学杂志

Idiopathic pulmonary fibrosis （IPF） is a common， lethal interstitial lung disease characterized by airway remodeling， inflammation， alveolar destruction， and fibrosis. The mammalian target of rapamycin complex 1/4E binding protein 1 （mTORC1/4E-BP1） axis is closely related to the expression of collagen by fibroblasts， and its role in pulmonary fibrosis remains to be further elucidated. Traditional Chinese medicine （TCM） has shown promising efficacy in improving the lung function， exercise capacity， and quality of life in patients with IPF. The theory of "same treatment for different diseases" provides a TCM theoretical basis for the treatment of pulmonary fibrosis with Bupleuri Radix， while the research in western medicine has preliminarily shown that both the formulation and single herb as well as the active ingredients of Bupleuri Radix have good therapeutic effects on pulmonary fibrosis. Therefore， this review will elaborate on the role of the mTORC1/4E-BP1 axis in the pathomechanism of IPF， as well as the research results of the active components of Bupleuri Radix on the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin protein（PI3K/AKT/mTOR） pathway， so as to provide a reference for the treatment and drug development of IPF.

BACKGROUND@#To observe the effects of Chinese medicine (CM) Polygonum cuspidatum (PC) on adenosine 5'-monophosphate-activated protein kinase (AMPK), forkhead box O3α (FOXO3α), Toll-like receptor-4 (TLR4), NACHT, LRR and PYD domains-containing protein 3 (NLRP3), and monocyte chemoattractant protein-1 (MCP-1) expression in a rat model of uric acid-induced renal damage and to determine the molecular mechanism.@*METHODS@#A rat model of uric acid-induced renal damage was established, and rats were randomly divided into a model group, a positive drug group, and high-, medium-, and low-dose PC groups (n=12 per group). A normal group (n=6) was used as the control. Rats in the normal and model groups were administered distilled water (10 mL•kg) by intragastric infusion. Rats in the positive drug group and the high-, medium-, and low-dose PC groups were administered allopurinol (23.33 mg•kg), and 7.46, 3.73, or 1.87 g•kg•d PC by intragastric infusion, respectively for 6 to 8 weeks. After the intervention, reverse transcription polymerase chain reaction, Western blot, enzyme linked immunosorbent assay, and immunohistochemistry were used to detect AMPK, FOXO3α, TLR4, NLRP3, and MCP-1 mRNA and protein levels in renal tissue or serum.@*RESULTS@#Compared with the normal group, the mRNA transcription levels of AMPK and FOXO3α in the model group were significantly down-regulated, and protein levels of AMPKα1, pAMPKα1 and FOXO3α were significantly down-regulated at the 6th and 8th weeks (P<0.01 or P<0.05). The mRNA transcription and protein levels of TLR4, NLRP3 and MCP-1 were significantly up-regulated (P<0.01 or P<0.05). Compared with the model group, at the 6th week, the mRNA transcription levels of AMPK in the high- and medium-dose groups, and protein expression levels of AMPKα1, pAMPKα1 and FOXO3α in the high-dose PC group, AMPKα1 and pAMPKα1 in the mediumdose PC group, and pAMPKα1 in the low-dose PC group were significantly up-regulated (P<0.01 or P<0.05); the mRNA transcription and protein levels of TLR4 and NLRP3 in the 3 CM groups, and protein expression levels of MCP-1 in the medium- and low-dose PC groups were down-regulated (P<0.01 or P<0.05). At the 8th week, the mRNA transcription levels of AMPK in the high-dose PC group and FOXO3α in the medium-dose PC group, and protein levels of AMPKα1, pAMPKα1 and FOXO3α in the 3 CM groups were significantly up-regulated (P<0.01 or P<0.05); the mRNA transcription levels of TLR4 in the medium- and low-dose PC groups, NLRP3 in the high- and low-dose PC groups and MCP-1 in the medium- and low-dose PC groups, and protein expression levels of TLR4, NLRP3 and MCP-1 in the 3 CM groups were down-regulated (P<0.01 or P<0.05).@*CONCLUSION@#PC up-regulated the expression of AMPK and its downstream molecule FOXO3α and inhibited the biological activity of TLR4, NLRP3, and MCP-1, key signal molecules in the immunoinflammatory network pathway, which may be the molecular mechanism of PC to improve hyperuricemia-mediated immunoinflflammatory metabolic renal damage.
