ABSTRACT
ObjectiveTo analyze the community structure of endophytes in Panax quinquefolium root and explore the dominant endophytic bacteria and fungi, to provide scientific basis for the establishment of endophytic microbial bank in P. quinquefolium root. MethodInternal Transcribed Spacer (ITS) sequencing and 16S sequencing were performed on six P. quinquefolium root samples collected from Wendeng, Shandong province on PacBio Sequel Ⅱ. ResultA total of 8 phyla, 11 classes, 23 orders, 27 families and 53 genera of endophytic bacteria were identified in P. quinquefolium root, among which an unidentified Burkholderiaceae and an unidentified Rhizobiaceae were dominant. A total of 9 phyla, 23 classes, 35 orders, 43 families and 48 genera of endophytic fungi were identified in P. quinquefolium root, among which an unclassified Helotiales and Pseudogymnoascus were dominant. The community structure of endophytic bacteria revealed that the roots were selectively enriched with nitrogen-fixing bacteria such as unidentified Rhizobiaceae, Bradyrhizobium and Herbaspirillum, which suggested that nitrogen is important for the growth of P. quinquefolium root. The community structure of endophytic fungi indicated that P. quinquefolium in Shandong province might be infected by unclassified Helotiales. ConclusionThere is a rich diversity of endophytic bacteria and fungi in P. quinquefolium root, which provides scientific basis for studying the interaction of the plant with endophytic microorganisms and screening the endophytes to promote the growth of P. quinquefolium root.
ABSTRACT
By reviewing ancient materia medica, prescription books, medical books and modern literature, this article makes a systematic textual research on the name, origin, commercial specification, producing area, harvesting and processing of Scutellariae Radix used in famous classical formulas according to the historical development, in order to provide a reference for the development and utilization of famous classical formulas. Scutellariae Radix was first named as Qian, Qin and so on, while Huangqin was used as the official name in ancient literature, as well as many aliases such as Fuchang, Huangwen and Dufu. The main origin of Scutellariae Radix in the past dynasties was Scutellaria baicalensis, and other Scutellaria plants were also used for Scutellariae Radix at different times. The medicinal parts of Scutellariae Radix in all dynasties are roots, since the Northern and Southern dynasties, it has gradually differentiated into Ziqin and Kuqin with different efficacy according to their different growth stages and characteristics, and continued to this day. At present, most of Scutellariae Radix are Ziqin in the market, due to the influence of cultivation cost, index component content requirements and other factors. The production area of Scutellariae Radix recorded in ancient literature was wide and gradually expanded from the Yangtze River basin to the northward. Since modern times, Chengde city of Hebei province has been respected as a geo-authentic area, now S. baicalensis is cultivated in a wide area, spreading over north and northeast China. Scutellariae Radix was mostly used as raw products in the early period, and a variety of processed products appeared in the Ming dynasty. Development continues to this day, Scutellariae Radix mainly includes raw products and wine-processed products. According to the research conclusion, it is suggested that S. baicalensis should be used as Scutellariae Radix in famous classical formulas, and the selection of its commercial specifications and processed products can be comprehensively determined according to the requirements of original prescription and the clinical effect.

Preoperative general conditions, cumulative dissipated energy(CDE), effective phacoemulsification time(EPT), postoperative best corrected visual acuity(BCVA), uncorrected visual acuity(UCVA), endothelial cell loss rate(ECL), central macular thickness(CMT)and complications were compared and analyzed.<p>RESULTS:There was no significant difference in preoperative general data between the two groups(<i>P</i>>0.05). In both groups, UCVA at 1d, 1wk and 1mo after surgery and BCVA at 1wk and 1mo after surgery were better than those before surgery, and at 1d after surgery, UCVA in FLACS group was better than that in Phaco group, the difference was statistically significant(<i>P</i><0.05). In the FLACS group, CDE, EPT, ECL at 1wk and 1mo after surgery, and the incidence of corneal edema at 1d and 1wk after surgery were all lower than those in the Phaco group(all <i>P</i><0.05). There was no significant change in CMT in either the intragroup comparison or the intergroup comparison(<i>P</i>>0.05).<p>CONCLUSION:FLACS is safe and effective in patients with shallow anterior chamber cataract, which can significantly reduce the rate of endothelial cell loss, quickly restore vision, reduce the incidence of complications, and has no significant effect on macula.
ABSTRACT
The purpose of this study was to investigate how Zuogui pills from the Kidney-tonifying and Nourishing Yin formula, in combination with the gonadotrophin-releasing hormone antagonist cetrorelix, affected the ovarian local oxidative stress response in decreasing ovarian reserve (DOR) mice. All animal experiments were carried out in accordance with the guidelines and standards established by Jinan University's Experimental Animal Management Committee. Cyclophosphamide (CTX)-treated DOR mice were given Zuogui pills, cetrorelix, or a combination of the two drugs intragastrically. After treatment, there were changes in the estrous cycle, serum sex hormone levels, oxidative stress-related indexes, growth biochemical factor levels, and SIRT1/P53/P21 expression. In comparison to the model group, the Zuogui pills and the cetrorelix+Zuogui pills group had significantly prolonged estrous periods and shortened interestrous periods, and the cetrorelix+Zuogui pills group had a significantly shortened cycle length. Follicle-stimulating hormone (FSH) decreased and estradiol (E2) increased in all treatment groups compared to the model group, oxidative stress indexes nitric oxide synthase (NOS), nitric oxide (NO), and reactive oxygen species (ROS) decreased, growth biochemical factors brain derived neurotrophic factor (BDNF) and growth differentiation factor 9 (GDF-9) concentrations increased significantly, and leukemia inhibitory factor (LIF) showed no significant change. SIRT1/P53/P21 immunohistochemical results revealed that, when compared to the model group, the expression of SIRT1 increased while the expression of P53 and P21 proteins decreased in all treatment groups, with the cetrorelix+Zuogui pills group having the largest decrease, with significant differences in all indicators. We conclude that cetrorelix combined with Zuogui pills for kidney nourishing and Yin recipe improved the oxidative stress response in the follicle by regulating the SIRT1/P53/P21 pathway, reducing peroxide product production, protecting ovarian function, and regulating ovarian hormone secretion, and its efficacy is superior to that of cetrorelix or Zuogui pills alone.
ABSTRACT
Objective:To explore the role and molecular mechanism of DNAJB6 in liver regeneration during partial liver transplantation(PLT).Methods:Dark agouti(DA, donor)and Lewis(recipient)rats were prepared for liver regeneration model of PLT.Rats were divided into before perfusion, after split liver perfusion, after portal vein opening, before abdominal closure and Day 3/7 after surgery groups(n=6 each)for timepoints of PLT.C57 mice were performed for residual liver regeneration model of partial hepatectomy and divided into control, Day 1/2/3/4/5 groups(n=6 each)for timepoints of hepatectomy.Gene Expression Omnibus liver regeneration data were utilized for locating DNAJB6 in liver regeneration.DNAJB6 low-expression human hepatocytes were constructed by DNAJB6-Si transfection.The relationship between DNAJB6 and liver regeneration was examined by Western blot detection of cell proliferation markers PCNA and CCK8 cell proliferation experiments.And the possible molecular mechanism of DNAJB6 regulating liver regeneration in PLT was studied by Western blot detection of nuclear protein and protein in cell proliferation signal pathway.Results:The result of residual liver regeneration of partial hepatectomy showed that DNAJ family genes were differentially expressed on regenerated liver gene chip and DNAJB6 was lowly expressed on regenerated liver gene chip.Meanwhile, DNAJB6 was lowly expressed in regenerated liver tissues of PLT and partial liver resection.After silencing DNAJB6 by transfecting DNAJB6-Si, the cellular expression level of PCNA and proliferation rate increased.However, nuclear extraction failed to detect the nuclear/plasma changes of β-catenin and the level of Wnt4 protein had no obvious change.Although the activation levels of p38 and JNK2 downstream of Ras/MAPK showed no change, there was a higher activation level of ERK.Conclusions:In regenerating liver tissue, hepatocytes may suppress the Ras/MEK/ERK signaling pathway by lowering the expression level of DNAJB6 to promote liver regeneration.
ABSTRACT
Global efforts to identify groups at high risk for schistosomiasis have mainly concentrated on identifying their geographical distribution. Investigations on the socioeconomic characteristics of high-risk groups are relatively scarce. This study aimed to explore the associations between schistosomiasis among students and their parents’ occupations. A nationwide cross-sectional survey was conducted targeting 105,167 students in 1,772 primary schools across Sudan in 2017. From these students, 100,726 urine and 96,634 stool samples were collected to test for Schistosoma haematobium and S. mansoni infection. A multi-level mixed effect analysis was used with age and sex as fixed factors, and school as a random factor. The odd ratios (ORs) of practicing open defecation among farmers’ children were almost 5 times higher than their counterparts whose parents were government officials (OR=4.97, 95% confidence intervals (CIs): 4.57-5.42, P<0.001). The ORs of contacting water bodies for watering livestock among farmers’ children were more than 4 times higher than those of children whose parents were government officials (OR=4.59, 95% CIs: 4.02-5.24, P<0.001). This study shows that schistosomiasis represents a disease of poverty and that farmers’ children constituted a high-risk group.

ObjectiveUncommon medicinal herbs are valuable medicinal resources, but their identification is a difficult problem in Chinese medicine due to their particularity and complexity. It is, therefore, urgent to establish a method for the identification of uncommon medicinal herbs. In this study, DNA signature sequence (DSS) tags were used to establish a specific polymerase chain reaction (PCR) identification method for Hibisci Cortex, the origin plant of Hibisci Cortex, and its adulterants. MethodThe candidate DSS tags were obtained from the chloroplast genome sequence analysis, and the DSS tags were verified by DNA sequencing. The specific identification primers for H. syriacus were designed based on the obtained reliable DSS tags. The PCR reaction conditions were optimized, and the tolerance and feasibility were investigated. ResultA DSS tag for identification of H. syriacus was obtained from the comparison of sequencing results of the amplified products with DSS, which revealed the distinguishing characteristics of Hibisci Cortex and its adulterants. A pair of specific primers for H. syriacus was designed according to the DSS tag. After PCR amplification and gel electrophoresis with the primers, a single bright band of about 270 bp was observed from H. syriacus, which did not appear in the four adulterants. ConclusionA DSS tag obtained in this study can be used to identify H. syriacus. The specific primers designed based on this DSS tag can accurately and simply identify the original plant of Hibisci Cortex and its adulterants, which provides a new method and idea for the molecular identification of genuine and counterfeit products of Hibisci Cortex.

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
Through consulting the ancient and modern literature, this paper makes a textual research on the name, origin, producing area, harvesting and processing of Poria, so as to provide a basis for the development of the famous classical formulas containing this medicinal material. The description of Poria and the characteristics of the attached figures in the Chinese herbal literature of the past dynasties are consistent with Poria cocos. The medicinal parts are dried sclerotia or P. cocos peel. Poria was originally produced in Taishan, Shandong province. In the Tang dynasty, along with the change of pine forest resources, producing area of Poria was transferred to Huashan area in Shaanxi province. In the Ming dynasty, the authentic producing area was transferred to Yunnan, and has continued to now. In ancient times, the processing methods of Poria were steaming, boiling, slicing, mashing and other subsequent processing after peeling. It is suggested that Poria in famous classical formulas should be sliced according to the 2020 edition of Chinese Pharmacopoeia.
ABSTRACT
Through consulting the ancient and modern literature, this paper makes a textual research on the name, origin, producing area, harvesting and processing methods of Asini Corii Colla, so as to provide a basis for the development of the famous classical formulas containing the medicinal material. Before the Tang dynasty, cow leather was the main source of Asini Corii Colla, and donkey was rare as an introduced species. From the end of Tang dynasty to Song dynasty, due to the development of doctors' understanding of the properties and effects of medicines, with the increase of the number of donkeys and the limitation of the use of cow leather, the source of Asini Corii Colla changed from cow leather to donkey skin. During the Ming and Qing dynasties, the theory of medicine property was further developed, and all doctors basically agreed that black donkey skin and E-well water were two essential factors for making genuine Asini Corii Colla. Therefore, it is suggested that Asini Corii Colla should take Equus asinus as the authentic origin in the development of the famous classical formulas, attach importance to the quality of water source, take Liaocheng in Shandong province as the authentic producing area, and the processing should be carried out in accordance with the requirements of the 2020 edition of Chinese Pharmacopoeia.
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
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
In this paper, the name, origin, producing area, quality evaluation, harvesting and processing methods of Scrophulariae Radix used in the famous classical formulas were researched by consulting related ancient materia medica, medical books and prescription books. The results showed that the name of Scrophulariae Radix originated from its shape and color. Scrophularia ningpoensis, one of the eight flavors of Zhejiang, has been highly praised in the past as a genuine base, and its authentic production area is Zhejiang. Quality of Scrophulariae Radix is best if it has a dry body, thin skin, thick branches, firm physique, black inner color, net basal part of stem, and no fine whiskers. In ancient times, the origin processing was divided into two types, including sun-dried after steaming and directly sun-dried. While it mostly used a combination of drying and sweating in modern times. Before the Ming dynasty, the processing of Scrophulariae Radix was mainly steamed. Occasionally, the stir-frying appeared. In the Ming dynasty and after the Ming dynasty, wine processing emerged such as hot wine mixed roasting, wine washing, wine steaming, because the ancients believed that wine could enhance its efficacy and reduce its cold property. In the Qing dynasty, the method of steaming and baking appeared in the water and fire system. According to the 2020 edition of Chinese Pharmacopoeia, the processing of Scrophulariae Radix includes removing rhizome residues and impurities, washing, moistening, cutting into thin slices, and drying, or soaking slightly, steaming thoroughly, drying slightly, cutting into thin slices, and drying. Referring to the relevant national documents, it is suggested that raw products of Scrophulariae Radix should be used in Liangditang and Simiao Yong′antang.
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
In this paper, the name, varieties, raw materials and manufacturing technology of maltose in the famous classical formulas were researched by consulting the herbal medicines, medical books, prescription books and modern literature of past dynasties, which provided the basis for the development and utilization of formulas containing maltose. Through textual research, it can be seen that the name of maltose has been derived from its shape, texture, preparation method, raw materials and producing area. In ancient times, maltose was mainly divided into soft and hard types according to the texture. Those who are wet and soft as honey are called "syrup" or "jelly", while those who are hard and white are called "malt" and "sugar". In modern times, they are mostly called malt sugar, only jelly is used as medicine, and malt is mostly used as food. Throughout the ages, medicinal maltose were made of Oryza sativa var. glutinosa as the raw material and Hordeum vulgare as malt, prepared by fermenting, decocting and concentrating. The maltose made from other cereals such as Setaria italica var. germanica, Panicum miliaceum is slightly inferior in quality. The 2020 edition of Chinese Pharmacopoeia did not include maltose, but included malt sugar, a pharmaceutical excipient, which was a crystal powder with high purity. But maltose was included in the national food standard and the local processing specification. Based on the textual research results, it is suggested that malt syrup in GB/T 20883-2017 can be used as the reference for the development of formulas containing maltose, and O. sativa var. glutinosa, H. vulgare are clearly used as raw materials.
