Acute kidney injury caused by rhabdomyolysis which is induced by intestinal infection: a case report and literature review / 中国基层医药

Objective:To report a case of acute kidney injury caused by rhabdomyolysis and summarize its etiology, pathogenesis, and treatment strategy.Methods:The clinical data of a case of rhabdomyolysis complicated by acute kidney injury admitted to Affiliated Huadu Hospital of Southern Medical University on August 30, 2020, were collected, including clinical manifestation, auxiliary examination, and disease outcome. Referring to the previous literature reports of rhabdomyolysis complicated by acute kidney injury, this paper discusses its etiology, monitors and analyzes some indicators such as serum creatinine, blood urea nitrogen, creatine kinase, myoglobin, and 24-hour urine volume during the treatment, and summarizes the clinical diagnosis and treatment ideas of the disease.Results:This case developed an intestinal infection after an unclean diet, which induced rhabdomyolysis and acute kidney injury. Renal pathology after renal biopsy showed that renal biopsy result was consistent with an acute tubulointerstitial injury caused by myoglobin tubular nephropathy. The biochemical indexes such as creatine kinase and myoglobin decreased rapidly after ordinary hemodialysis, but the levels of serum creatinine and blood urea nitrogen did not decrease markedly, and there was continuous oliguria. After switching to hemodialysis filtration and continuous intensive dialysis treatment, the levels of serum creatinine and blood urea nitrogen decreased rapidly, the amount of urine increased gradually, and finally, the renal function recovered.Conclusion:For acute kidney injury caused by rhabdomyolysis, early sufficient blood purification can accelerate the clearance of myoglobin, promote the recovery of the injured kidney, and improve the prognosis of the disease.

Significance of anti-Jo-1 antibody's clinical stratification in idiopathic inflammatory myopathy and disease spectrum / 北京大学学报(医学版)

OBJECTIVE@#To investigate the significance of anti-histidyl tRNA synthetase (Jo-1) antibody in idiopathic inflammatory myopathies (IIM) and its diseases spectrum.@*METHODS@#We enrolled all the patients who were tested positive for anti-Jo-1 antibody by immunoblotting in Peking University People's Hospital between 2016 and 2022. And the patients diagnosed with anti-synthetase antibody syndrome (ASS) with negative serum anti-Jo-1 antibody were enrolled as controls. We analyzed the basic information, clinical characteristics, and various inflammatory and immunological indicators of the patients at the onset of illness.@*RESULTS@#A total of 165 patients with positive anti-Jo-1 antibody were enrolled in this study. Among them, 80.5% were diagnosed with connective tissue disease. And 57.6% (95/165) were diagnosed with IIM, including ASS (84/165, 50.9%), immune-mediated necrotizing myopathy (7/165, 4.2%) and dermatomyositis (4/165, 2.4%). There were 23.0% (38/165) diagnosed with other connective tissue disease, mainly including rheumatoid arthritis (11/165, 6.7%), undifferentiated connective tissue disease (5/165, 3.0%), interstitial pneumonia with autoimmune features (5/165, 3.0%), undifferentiated arthritis (4/165, 2.4%), Sjögren's syndrome (3/165, 1.8%), systemic lupus erythematosus (3/165, 1.8%), systemic vasculitis (3/165, 1.8%), and so on. Other cases included 3 (1.8%) malignant tumor patients, 4 (2.4%) infectious cases and so on. The diagnoses were not clear in 9.1% (15 /165) of the cohort. In the analysis of ASS subgroups, the group with positive serum anti-Jo-1 antibody had a younger age of onset than those with negative serum anti-Jo-1 antibody (49.9 years vs. 55.0 years, P=0.026). Clinical manifestations of arthritis (60.7% vs. 33.3%, P=0.002) and myalgia (47.1% vs. 22.2%, P=0.004) were more common in the ASS patients with positive anti-Jo-1 antibody. With the increase of anti-Jo-1 antibody titer, the incidence of the manifestations of arthritis, mechanic hands, Gottron sign and Raynaud phenomenon increased, and the proportion of abnormal creatine kinase and α-hydroxybutyric dehydrogenase index increased in the ASS patients. The incidence of myalgia and myasthenia were significantly more common in this cohort when anti-Jo-1 antibody-positive ASS patients were positive for one and more myositis specific antibodies/myositis associated autoantibodies (P < 0.05).@*CONCLUSION@#The disease spectrum in patients with positive serum anti-Jo-1 antibody includes a variety of diseases, mainly ASS. And anti-Jo-1 antibody can also be found in many connective tissue diseases, malignant tumor, infection and so on.

Relationship of EGFR-TKI Targeted Therapy and Pyroptosis in Non-small Cell Lung Cancer / 肿瘤防治研究

Objective To explore the relationship between pyroptosis and treatment in non-small cell lung cancer patients treated with tyrosine kinase inhibitors targeted therapy. Methods Stable transfection strains with common EGFR mutations found in clinical practice were constructed through lentiviral transfection. LDH and Western blot experiments were conducted to determine the degree and mechanism of pyroptosis after osimertinib treatment. Animal experiments verified the effect of pyroptosis on treatment efficacy. ELISA was used to explore the potential connection between pyroptosis and tumor immunotherapy. Results After osimertinib treatment on stable lines, the EGFR-L858R mutation had obvious pyroptosis at the morphology and protein levels. Western blot experiment confirmed that pyroptosis was mediated by GSDME (P < 0.0001). Experiments through the overexpression of GSDME and corresponding animal studies discovered that the degree of pyroptosis affected the treatment outcome. Blood analysis revealed that the level of IL-1β secreted by EGFR-L858R and EGFR-L858R-GSDME-OE mice after treatment was higher than that of the control group (P < 0.0001), and it may regulate tumor immunity to a certain extent. Conclusion Osimertinib can induce pyroptosis in EGFR-L858R mutant strains mediated by GSDME, and the level of pyroptosis in cell lines is positively correlated with therapeutic effect to a certain extent.

Nature-effect transformation mechanism of mulberry leaves and silkworm droppings based on chemical composition analysis / 中国中药杂志

Starting with the relationship between mulberry leaves and silkworm droppings as food and metabolites, this study systematically compared the chemical components, screened out differential components, and quantitatively analyzed the main differential components based on ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and UPLC-Q-TRAP-MS combined with principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Moreover, the in vitro enzymatic transformation of the representative differential components was studied. The results showed that(1) 95 components were identified from mulberry leaves and silkworm droppings, among which 27 components only exist in mulberry leaves and 8 components in silkworm droppings. The main differential components were flavonoid glycosides and chlorogenic acids.(2) Nineteen components with significant difference were quantitatively analyzed, and the components with significant differences and high content were neochlorogenic acid, chlorogenic acid, and rutin.(3) The crude protease in the mid-gut of silkworm significantly metabolized neochlorogenic acid and chlorogenic acid, which may be an important reason for the efficacy change in mulberry leaves and silkworm droppings. This study lays a scientific foundation for the development, utilization, and quality control of mulberry leaves and silkworm droppings. It provides references for clarifying the possible material basis and mechanism of the pungent-cool and dispersing nature of mulberry leaves transforming into the pungent-warm and dampness-resolving nature of silkworm droppings, and offers a new idea for the study of nature-effect transformation mechanism of traditional Chinese medicine.

Objective:To investigate the prevalence of chronic constipation in maintenance hemodialysis (MHD) patients and analyze the risk factors of chronic constipation.Methods:Using the cross-sectional survey method, patients who received MHD in Huadu District People′s Hospital of Guangzhou from September 1, 2021 to September 30, 2021 were enrolled as the research objects. The patient′s demographic, general data and laboratory results were collected. The anxiety level and quality of life were assessed by questionnaires. The patients were divided into constipation group and non-constipation group according to whether they had chronic constipation. The Rome Ⅳ criteria was used to diagnose chronic constipation, and the differences of clinical data between the constipation group and the non-constipation group were compared. The risk factors of chronic constipation in MHD patients were analyzed by logistic regression analysis method.Results:A total of 321 MHD patients were enrolled in this study, with 168 males, 153 females and age of (59.5±13.4) years old (ranged from 29 to 87 years old). There were 160 patients (49.8%) with chronic constipation. The proportions of males, long dialysis age, taking sevelamer and lanthanum carbonate, diabetic nephropathy, and diabetes in the constipation group were higher than those in the non-constipation group, and the differences between the two groups were statistically significant (all P<0.05). The serum calcium, serum phosphorus, calcium-phosphorus product, anxiety scores, average weekly ultrafiltration volume/dry weight in the constipation group were significantly higher than those in the non-constipation group (all P<0.05), and the serum albumin, serum magnesium, urea clearance index (Kt/V) and geriatric nutritional risk index were significantly lower than those in the non-constipation group (all P<0.05). The results of logistic regression analysis showed that moderate to severe anxiety (moderate, OR=3.233, 95% CI 1.339-7.805, P=0.009; severe, OR=5.103, 95% CI 1.906-13.663, P=0.001), existed risk of nutrition (low risk, OR=3.705, 95% CI 1.440-9.533, P=0.007; moderate risk, OR=5.638, 95% CI 2.557-12.430, P<0.001; severe risk, OR=15.097, 95% CI 4.112-55.436, P<0.001), >60 years old (≤40 years old as a reference, OR=4.050, 95% CI 1.366-12.006, P=0.012), diabetes history ( OR=2.224, 95% CI 1.253-3.946, P=0.006), taking sevelamer ( OR=2.290, 95% CI 1.207-4.346, P=0.011), and calcium-phosphorus product ( OR=1.704, 95% CI 1.329-2.186, P<0.001), intact parathyroid hormone ( OR=1.013, 95% CI 1.003-1.022, P=0.007), blood urea nitrogen ( OR=1.092, 95% CI 1.002-1.189, P=0.045) and serum magnesium ( OR=0.042, 95% CI 0.006-0.294, P=0.001) were the independent influencing factors for chronic constipation in MHD patients. Conclusions:The prevalence of chronic constipation in MHD patients is 49.8%. Adequate dialysis, improving calcium and phosphorus metabolism, improving nutritional status, relieving anxiety, and increasing serum magnesium level may help to reduce the risk of chronic constipation in MHD patients.

ObjectiveTo explore the regulatory effect of Gouqi chewable tablets on innate and adaptive immunity in normal mice and its antioxidant activity in vitro and in vivo. MethodThe effects of low-， medium-， and high-dose groups （0.25， 0.5， 1.5 g·kg-1） on the immune function of normal mice were observed by carbon clearance test， immune organ index test， serum hemolysin test， ConA-induced splenic lymphocyte proliferation test， and natural killer cell （NK cell） activity test. The effects of Gouqi chewable tablets on the antioxidant capacity in vivo were determined by detecting the content of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， and malondialdehyde （MDA） in mice serum. The in vitro antioxidant activity of Gouqi chewable tablets was detected by 2，2'-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid） diammonium salt （ABTS）， 2，2-diphenyl-1-picrylhydrazyl （DPPH）， and hydroxyl radical scavenging tests. ResultCompared with the blank control group， the low-， medium-， and high-dose groups of Gouqi chewable tablets improved the viability of NK cells， the proliferation of splenic lymphocytes， and the level of serum hemolysin antibody in mice （P<0.05）. The high-dose group increased the thymus index， spleen index， and phagocytic function of macrophages （P<0.05， P<0.01）. As compared with the blank control group， the activity of GSH-Px in mice serum in the medium-dose group was increased （P<0.05）， and the content of MDA in mice serum in the high-dose group was decreased （P<0.05）. In in vitro antioxidant tests， the median inhibitory concentration （IC50） values of Gouqi chewable tablets were 1.64±0.20， 2.04±0.03， and 10.27±0.03 g·L-1 by the DPPH， ABTS， and OH- free radical method， respectively. Those results indicated that Gouqi chewable tablets have good antioxidant effects in vitro. ConclusionGouqi chewable tablets can enhance the immune function of mice with good antioxidant effects.

Herbal Textual Research on Astragali Radix in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Poria in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Asini Corii Colla in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Magnoliae Officinalis Cortex in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Jujubae Fructus in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Scrophulariae Radix in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Chuanxiong Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Maltose in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Bambusae Caulis in Taenias in Famous Classical Formulas / 中国实验方剂学杂志

By consulting the ancient herbal and medical books， combined with modern literature， the name， origin， geoherbalism， harvesting and processing changes of Bambusae Caulis in Taenias in famous classical formulas were sorted out. According to the research， ancient doctors only approved three kinds of bamboo medicinal materials， namely， Jinzhu （䈽竹）， Kuzhu （苦竹） and Danzhu （淡竹）， and took bamboo leaves， made Bambusae Caulis in Taenias and Zhuli （竹沥） for medicine. Bamboo medicinal materials with different origins have different properties， tastes and effects， after clinical optimization， it is gradually considered that Danzhu is the best source of Bambusae Caulis in Taenias and Zhuli. According to the morphological description of the original plants and the attached drawings， it is considered that the Danzhu in ancient Chinese materia medica should be Phyllostachys nigra var. henonis， which has been included in the 2020 edition of Chinese Pharmacopoeia as one of the genuine sources of Bambusae Caulis in Taenias. Therefore， It is suggested that P. nigra var. henonis can be added as the source of Bambusae Caulis in Taenias in famous classical formulas， and the medicinal part is the dry middle layer of its stem. Ginger-processed can increase the anti emetic effect of Bambusae Caulis in Taenias， and the three formulas involving Bambusae Caulis in Taenias from The Catalogue of Ancient Famous Classical Formulas （The First Batch） all contain ginger， and the processing method of Bambusae Caulis in Taenias is not marked in the original formula， so it is suggested to use raw products in the three formulas of Jupi Zhurutang， Wendantang and Zhurutang.

Herbal Textual Research on Alismatis Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

In this study， name， origin， producing areas， harvesting time and processing methods of ancient Alismatis Rhizoma were systematically researched by consulting the literature of ancient herbs， medical and prescription books， so as to provide a basis for the development of famous classical formula containing this herb. According to textual research， the main base of ancient Alismatis Rhizoma was Alisma plantago-aquatica and A. orientale. A. canaliculatum and A. gramineum and other genera were sometimes used as the source of Alismatis Rhizoma， there was a confusion of medicinal varieties. The earliest producing area of Alismatis Rhizoma was in today's Henan province， and later Hanzhong， Shaanxi province， became the high-quality producing area of Alismatis Rhizoma. Since the Ming dynasty， its production area expanded to Fujian. In the Qing dynasty， Jian'ou in Fujian was the authentic production area of Alismatis Rhizoma. In the period of the Republic of China， Sichuan and Jiangxi were added to the production areas of Alismatis Rhizoma. Based on the research results， it is suggested that the dried tubers of A. orientale from Fujian and Jiangxi or A. plantago-aquatica from Sichuan should be used in the famous classical formulas. In ancient times， Alismatis Rhizoma was processed by wine， but most of the standards and specifications in modern times are no longer included the processing specifications of Alismatis Rhizoma with wine. Although salt-processed Alismatis Rhizoma is commonly used in modern times， it didn't become one of the main processing methods until the Qing dynasty. According to the relevant national documents， it is suggested that Alismatis Rhizoma without clear processing requirements in famous classical formulas should be used as raw products， and the formulas with processing requirements should be selected as processed products such as salt and wine according to the meaning of the formulas.

Herbal Textual Research on Dendrobii Caulis in Famous Classical Formulas / 中国实验方剂学杂志

Through consulting the ancient herbal and medical books， combined with the field investigation， the name， origin， collection and processing of Dendrobium medicinal materials were researched， which provided a basis for the development of famous classical formulas containing this kind of herbs. Due to the wide distribution of D. officinale， the Dendrobium species represented by D. officinale and D. huoshanense， which are short， fleshy and rich in mucus， should be the most mainstream of Dendrobium medicinal materials in previous dynasties. Compared with Shihu， Muhu with loose texture， long and hollow is born on trees. According to the characteristic description， it should be D. nobile， D. fimbriatum and so on， of which D. nobile was the mainstream. The Chinese meaning of Jinchai was confused in the past dynasties， so it was not suitable to be treated as a plant name. The production areas of Dendrobium medicinal materials in the past dynasties have changed with the discovery of varieties， artificial cultivation and other factors. Lu'an， Anhui province， was the earliest recorded in the Han and Wei dynasties. Since the Tang and Song dynasties， it had been extended to Guangdong and Guangxi， and it was considered that "Dendrobii Caulis in Guangnan was the best". In the Ming dynasty， Sichuan and Zhejiang products were highly praised， and in the Qing dynasty， Huoshan products were highly praised. Dendrobium medicinal materials had been used as medicine by stems in all dynasties. The medicinal materials were divided into fresh products and dry products. The fresh products can be used immediately after removing the sediment from the roots. The dry products need further processing， most of them used wine as auxiliary materials for steaming， simmer to paste or decoction into medicine. D. officinale and D. huoshanense have special processing specifications since the middle of Qing dynasty， that is， "Fengdou". According to the research results， in Ganluyin， the effect of Dendrobium medicinal materials is mainly heat clearing， and D. nobile with bitter taste can be selected. The main effect of Dendrobium medicinal materials in Dihuang Yinzi is tonic， D. officinale or D. huoshanense can be selected.

Textual Research on Perillae in Famous Classical Formulas / 中国实验方剂学杂志

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 Zisu （Perillae） in the famous classical formulas， so as to clarify the information of the drug in different historical periods and provide a reference for the development and utilization of the related formulas. The main origin of Perillae in the ancient literature was Perilla frutescens var. frutescens （purple leaf type）， followed by P. frutescens var. acuta （purple leaf type）， but not Baisu. Modern chemical composition studies also show that there are obvious differences between Perillae and Baisu， which provides a scientific basis for distinguishing them. Although they are often treated as a species in plant classification， P. frutescens var. frutescens （purple leaf type） is recommended in the development of famous classical formulas， and Baisu should be avoided. Perillae is widely distributed， but its producing area did not record in most of the literature in the past dynasties， or the producing area is described as everywhere today. In the period of the Southern and Northern dynasties， the medicinal parts of Perillae included stems， leaves and seeds， and doctors in the Ming dynasty began to pay attention to the differentiation of different medicinal parts. The harvesting and processing methods of Perillae in the past dynasties are close to that of today. Perillae Fructus is mostly stir-fried and ground into medicine， Perillae Folium and Perillae Caulis are mainly simple cleansing. In production， we can refer to the 2020 edition of Chinese Pharmacopoeia.

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.

Analysis of the etiology and clinical characteristics of infants with moderate-severe visual impairment / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the etiology classification and clinical characteristics of infants with moderate-severe visual impairment aged 0-2 years old, and preliminarily formulate a set of process for grass-roots health-care institutions to carry out the screening and management of children visual impairment.METHODS: There were 245 cases of children aged 0-2 years with moderate-severe visual impairment who were admitted to the Children Eye Care Specialist Clinic in Nanjing Maternal and Child Health Hospital from January 2009 to December 2020 were retrospectively analyzed. A complete profile of visual development was established, including age, sex, medical history, vision, eye position and movement, anterior segment examination, fundus examination, refractive examination under cycloplegia with 1% atropine ophthalmic gel, if necessary, some special eye examinations such as fundus photography, eye A/B ultrasound and visual electrophysiology were received.RESULTS: The average visit age of 245 cases of infants was 1.82±0.79 years, including refraction error of 128 cases(52.2%), among them, 100 cases(40.8%)were high refraction error; 79 cases(32.2%)were eye diseases, most of which were congenital cataract(33 cases); and 38 cases(15.5%)were cerebral visual impairment(CVI)(15.5%).CONCLUSION: It is necessary to proceed classified managements according to the etiology and clinical characteristics of infant visual impairment to find early and diagnose and treat multidisciplinary,including drawing up screening plans for remediable eye diseases, carrying out necessary refractive correction and training children to use residual visual function.
