[Objective]To investigate the protective effect and mechanism of Ganoderma lucidum extract(GLE)on liver cirrhosis in mice.[Methods]Ten male C57BL/6 mice were randomly selected as control group,the remaining forty mice were intraperitoneally injected with carbon tetrachloride olive oil suspension to induce liver cirrhosis model.They were randomly divided into model group and GLE low(50 mg/kg·d),medium(100 mg/kg·d)and high(200 mg/kg·d)dose groups,while the control group and model group received 0.9％sodium chloride solution gastric irrigation,and the control group mice were given the same volume of olive oil solution twice a week.Liver index was calculated.The activities of alanine aminotransferase(ALT),aspartate transaminase(AST)and the levels of total cholesterol(TC),total bilirubin(TB)and creatinine(Cr)in serum of mice were detected by automatic biochemical analyzer.Hematoxylin eosin(HE)staining was used to observe the histopathological changes of liver,and Masson staining was used to observe the degree of liver fibrosis.Terminal-deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL)staining was used to observe the apoptosis of hepatocytes.The levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-6,malondialdehyde(MDA)and activity of superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in serum were detected by enzyme linked immunosorbent assay(ELISA).The relative expression of nuclear factor E2 related factor 2(Nrf2)and nuclear Nrf2,heme oxygenase-1(HO-1)and NAD(P)H:quinone oxidoreductase 1(NQO1),α-smooth muscle actin(α-SMA),Collagen Ⅰ and E-cadherin protein in liver tissue were detected by Western blot.[Results]Compared with control group,the liver had significant damage,the liver index,serum ALT,AST activities,TC,TB and Cr levels,liver fibrosis degree,hepatocyte apoptosis index,the levels of serum TNF-α,IL-1 β,IL-6 and MDA,the relative expression of α-SMA and Collagen I protein increased(P＜0.05),while the activity levels of serum SOD and GSH-Px,and the relative expression of total Nrf2 and nuclear Nrf2,HO-1,NQO1 and E-cadherin protein in liver tissue decreased in model group(P＜0.05).Compared with model group,liver injury gradually reduced,the liver index,serum ALT,AST activities,TC,TB and Cr levels,liver fibrosis degree,hepatocyte apoptosis index,the levels of serum TNF-α,IL-1β,IL-6,MDA and the relative expression of α-SMA,Collagen I protein decreased(P＜0.05),while the activity levels of serum SOD and GSH-Px,and the relative expression of Nrf2 and nuclear Nrf2,HO-1,NQO1 and E-cadherin protein in liver tissue increased in GLE low,medium and high dose groups(P＜0.05).[Conclusion]GLE can alleviate the histopathological damage and improve liver function in cirrhotic mice.This may be related to the decreased level of oxidative stress and inflammatory reaction after activation of Nrf2/ARE signaling pathway,which may interfere with liver fibrosis.

Objective:To investigate the early auditory discrimination of vowels, consonants and lexical tones in prelingually-deafened children with cochlear implants (CI) using auditory event-related potentials.Methods:Nineteen prelingually-deafened CI children and 19 normal hearing (NH) children were recruited in this study. A multi-deviant oddball paradigm was constructed using the monosyllable/ta1/as the standard stimulus and monosyllables/tu1/,/te1/, /da1/,/ra1/,/ta4/and/ta2/as the deviant stimuli. The event-related potentials evoked by vowel, consonant and lexical tone contrasts were recorded and analyzed in the two groups.Results:NH children showed robust mismatch negativities (MMNs) to vowel, consonant and lexical tone contrasts ( P<0.05), whereas CI children only showed positive mismatch responses (pMMRs) and P3a responses to the vowel ( P<0.05) and consonant contrasts ( P<0.05) and no significant event-related potential to the lexical tone contrasts ( P>0.05). The longer pMMR and P3a peak latencies ( P<0.01) but similar amplitudes ( P>0.05) were found in CI children than in NH children. CI children showed weaker phase synchronization of θ oscillations than NH children ( P<0.05). The duration of CI use was positively correlated with the scores of Categories of Auditory Performance (CAP) ( P=0.004), Speech Intelligibility Rate (SIR) ( P=0.044) and Meaningful Auditory Integration Scale (MAIS) ( P=0.001) in CI children. Conclusions:Prelingually-deafened CI children can process vowels and consonants at an early stage. However, their ability of processing speech, especially lexical tones, is still more immature compared with their NH peers. The event-related potentials could be objective electrophysiological indicators reflecting the maturity of CI children′s auditory speech functions. Long-term CI use is beneficial for prelingually-deafened children to improve auditory and speech performance.

Flap surgery is a complex surgical procedure that has become an effective method for the treatment of many diseases and traumas. Flap survival is closely related to a variety of factors including cellular autophagy, oxidative stress, inflammatory response, mesenchymal stem cells (MSCs) function, and vascular regeneration. Cellular autophagy maintains intracellular homeostasis and plays a key role in reducing oxidative stress and inflammation and promoting injury repair. Excessive oxidative stress and inflammatory responses pose a threat to flaps, affecting their survival and successful transplantation. Endothelial cells are involved in vascular regeneration through proliferation, migration, and production of angiogenic factors, and vascular endothelial growth factor directly promotes blood vessel formation and maintains endothelial cell function.MSCs play an important role in promoting flap survival and tissue repair due to their unique biological properties and multiple mechanisms of action. The multiple roles played by cellular autophagy, oxidative stress, inflammatory response, MSCs function, and vascular regeneration in influencing postoperative flap survival are hereby elaborated. The aim is to provide a basis for the clinical application of regulating the above factors to improve postoperative flap survival, improve the success rate of flap surgery, reduce complications, and bring more hope for the recovery and quality of life of patients.

Liangmianzhen(Zanthoxyli Radix) has long been used as medicine. The current medicinal parts are different from those in the ancient. As recorded in the Chinese Pharmacopeia, the medicinal part is root. However, in ancient works, the medicinal parts include root, stem, leaf, and fruit. In an attempt to find the historical basis that stem is a reasonable medicinal part, the herbalogical study was carried out on this medicinal based on the formal names, synonyms, original plant, medicinal parts, habitat of the medicinal plant, producing area, processing and preparation methods, efficacy, and indications recorded in ancient Chinese materia medica and local gazetteers. The results showed that Liangmianzhen was firstly recorded as a medicinal in Shennong's Classic of Materia Medica with the formal name of "Manjiao". "Manjiao" was adopted from the Han Dynasty to the Qing Dynasty when it was changed to "Rudijinniu", the name originating from the folk in the south of the Five Ridges. Now, the formal name is "Liangmianzhen", which was firstly recorded in Wuxuan County Gazetteer in 1914 and then as a synonym in the Updated Records of Picking Herbs in the South of the Five Ridges. According to the formal names, synonyms, and the descriptions of the original plant, the medicinal plants of Liang-mianzhen have the characteristics of shrub-like young seedlings, vine adult seedlings, corymbiform thyrsus, stems with thorns, amphitropous golden-yellow roots with horn-like branches, and thorns on both sides of the leaves. Thus, "Manjiao", "Rudijinniu", and "Liangmianzhen" were from the same species of Zanthoxylum nitidum(Rutaceae), which was also verified based on the growth environment, habitat, processing and preparation methods, efficacy, and indications. In ancient times, the stem and root were the main medicinal parts and leaves and fruits were also used. However, in the Chinese Pharmacopeia, root is recorded as the only medicinal part, which is obviously inconsistent with the records in the ancient classics. In light of the limited medicinal resources for Liang-mianzhen, other medicinal parts of Z. nitidum is recommended. This study clarified the medicinal parts of Z. nitidum in history. It is recommended that the stem be added to the medicinal parts of Z. nitidum in the next edition of Chinese Pharmacopeia.

The aim of this study was to investigate the effect of transmembrane 9 superfamily protein member 2 (TM9SF2) in proliferation and migration of triple negative breast cancer cell line MDA-MB-231.The expression of TM9SF2 in triple negative breast cancer cell line MDA-MB-231 and nontumorigenic mammary epithelial cell line MCF-10A were measured by Western blot. MDA-MB-231 cells were treated with siRNA-TM9SF2 to knock-down the expression of TM9SF2. The effect of silencing TM9SF2 was measured with Western blot.The proliferation of cells was tested by MTS,and the migration was measured with Transwell and wound-healing assay.Proteins related to proliferation (PI3K,AKT,SRC and ERK) and migration (Snail,Slug and N-cadherin) were measured with Western blot.Protein expressions of TM9SF2 was better improved in triple negative breast cancer MDA-MB-231 cell line than MCF-10A.Compared with the control group, the siRNA-TM9SF2 infected group had lower expressions of PI3K, Snail, Slug and N-cadherin, and at the same time phosphorylation of AKT was decreased. The results suggest TM9SF2 can promote the proliferation and metastasis of triple negative breast cancer MDA-MB-231 cell line.

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc. Among them, stir-frying, and stir-frying with the earth scraped from the wall facing east are still used nowadays. The bran stir-frying is the improved version of glutinous rice stir-frying in order to be adaptive to the modern-day situation and the needs of the present. In addition, the ancient shell removal and kernel keeping method are also included in the processing procedures in modern local processing specifications, which are combined with frying to form a new method named "Fazhi" processing( "Fazhi" means a processing method of multiple procedures). The 2015 edition of Chinese Pharmacopoeia records that Coicis Semen is helpful to clear dampness and promote diuresis, strengthen the spleen and prevent diarrhea, eliminate impediment, discharge pus, resolve toxin and a mass, etc., which are consistent with those contained in ancient monographs on materia medica. After the "Fazhi" processing, the cold nature of Coicis Semen has been removed and its nature,flavour and meridian tropism have been changed, so its application scopes expanded. The results of this study clearly traced the history of the collecting and proces-sing of Coicis Semen, summarized the nature, flavour and efficacy of Coicis Semen contained in both ancient and modern literature, and provided a historical basis for the standardization of the subsequent processing technology of Coicis Semen, the clinical application of various processed products, and the further development and utilization of medicinal materials.

As a representative foreign medicinal material, olibanum(Ruxiang) was imported to China since the Qin and Han Dynasties. Olibanum was first described as a medicinal by the name "Xunluxiang" in Miscellaneous Records of Famous Physicians(Ming Yi Bie Lu). This study investigated historical records on olibanum and conducted the herbalogical study. It was found that olibanum came from the resin mainly obtained from the bark of Pistacia lenticus before the Tang Dynasty. With the prosperity of the Maritime Silk Road, instead, the resin obtained from the bark of Boswellia carterii was mainly used as olibanum. In ancient time, the oleo-gum-resin secreted from the cut bark was collected in spring and summer, and the quality was judged based on transparency and shape. The processing methods of olibanum went through many evolutions, which changed from simple methods such as grinding and frying to complex methods such as levigating and grinding with wine, and now to frying and processing with vinegar. The usage of olibanum included alchemy, folk and religious incense, bathing, cosmetic and medicinal since ancient times. From the Song Dynasty, olibanum had been mainly used as medicinal because of its good effect to treat wounds. In traditional Chinese medicine, olibanum unblocks menstruation, relieves pain and reduces swelling and generated muscles. The medicinal efficacy of olibanum is not much different from ancient to modern. Only the efficacy of replenishing energy and promoting the movement of Qi was rarely mentioned in modern reference. In this article, the historical evolutions of olibanum about original plants, processing and medicinal efficacy were sorted out. The results could provide historical basis for the further development and clinical utilization of olibanum.
