Sangjuyin, as a pungent and cooling agent with precise therapeutic effect, is a classic pungent formula for cooling relief of the epidermis, which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty, on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition, concoction, decoction, efficacy, and previous and modern application of Sangjuyin. After examination, the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris, family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa, family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx, family Labiatae. Mori Folium is the dried leaves of Morus alba, family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium, family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum, family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family, and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum, 5.60 g Forsythiae Fructus, 2.98 g Menthae Haplocalycis Herba, 9.33 g Mori Folium, 3.73 g Chrysanthemi Flos, 7.46 g Platycodonis Radix, 2.98 g Glycyrrhizae Radix et Rhizoma, and 11.19 g Phragmitis Rhizoma, with 400 mL water added, and the solution was boiled to obtain 200 mL, taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat, promoting lung and relieving cough, and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough, pneumonia, rhinitis, and other respiratory diseases, and the results of this study provide a reference for the later development of Sangjuyin.

Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore, in this study, we conducted systematic research into the historic origin, composition, and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions, with "Neixian Fufang", "Jiawei Jianghuangwan", "Peizhensan", and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty, inherited and developed by YANG Lishan from Qing dynasty, and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan, and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties, the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan, Bombyx Batryticatus of 74.6 g, Curcumae Longae Rhizoma of 9.325 g, Cicadae Periostracum of 9.325 g, and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g, Curcumae Longae Rhizoma of 0.14 g, Cicadae Periostracum of 0.14 g, and Rhei Radix et Rhizoma of 2.3 g, with halved dosage applied for children. For the powder version of Shengjiangsan, the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g, Curcumae Longae Rhizoma of 0.28 g, Cicadae Periostracum of 0.92 g, and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g, Curcumae Longae Rhizoma of 0.37 g, Cicadae Periostracum of 1.23 g, and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g, Curcumae Longae Rhizoma of 1.84 g, Cicadae Periostracum of 0.55 g, and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula, four herbs were ground to fine powder. For patients with mild symptoms, the whole formula was divided into four dosages, and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added, and the solution was stirred and taken cold till full recovery. For patients with severe symptoms, the whole formula was divided into three dosages, and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added, and the solution was stirred and taken cold. For patients with critical conditions, the whole formula was divided into two dosages, and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added, and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity, dissipating wind, and clearing heat. It is specialized in treating severe heat in exterior, interior, and triple energizers in warm diseases and has a wide modern clinical application. In this study, the historic evolution and key information of Shengjiangsan were reviewed and analyzed, and the key information table of Shengjiangsan was attached, serving as a reference for scholars' research and a theoretical basis for its market transformation.

Objective:To investigate the affection of high mobility group nucleosome-binding protein 5(HMGN5) gene in the hepatocellular cancer tissue and HepG2 cell and its function in the growth of HepG2 cell.Methods:70 Patients with hepatocellular carcinoma who under-went surgical resection and were confirmed by postoperative pathology in Sunshine Union Hospital of Weifang City from January 2017 to June 2020 were selected. Their clinical and pathological data, surgical resection of liver cancer tissue and adjacent normal liver tissue were collected, their survival time were also recorded. The contents of HMGN5 protein in the hepatocellular cancer tissues and adjacent normal liver tissues of 70 patients were detected by immunohistochemistry. Compare the expression of HMGN5 protein in liver cancer tissue and normal liver tissue and the positive expression rate of HMGN5 protein in liver cancer tissues of hepatocellular carcinoma patients with different clinical characteristics, to analyze the relationship between HMGN5 expression and prognosis of patients with hepatocellular carcinoma.The mRNA contents of HMGN5 gene in HepG2 cells and HL-7702 cells were determined by quantitative real time polymerase chain reaction(qRT-PCR) method. After transfectHepG2 cells with HMGN5 shRNA, the proliferation ability of HepG2 cells were evaluated by cell proliferation assay and the cell apoptosis was analyzed by flow cytometry. Measurement data with normal distribution were expressed as ±s, two independent samples t test was used for comparison between groups. Counting data was expressed as n(%), χ2 test was used for comparison between groups. Survival analysis of patients was performed by Kaplan-Meier method. Results:Immunohistochemical tests showed that HMGN5 staining is strong in liver cancer tissue, but weak in normal liver tissue. HMGN5 protein expression was positive in 48 of 70 patients with hepatocellular carcinoma. The positive expression rate of HMGN5 protein in hepatocellular carcinoma tissues of patients with pathological grade 3+4 and clinical stage Ⅲ+Ⅳ was higher than that of patients with grade 1+2 and stage Ⅰ+Ⅱ, respectively. There was no significant difference in cumulative survival rate between HMGN5 positive expression group and HMGN5 negative expression group ( χ2=3.81, P=0.051). The results of qRT-PCR showed that the expression level of HMGN5 mRNA in hepatoma HepG2 cells was higher than that in normal liver HL-7702 cells [(4.51±0.45) vs (1.35±0.27), the difference was statistically significant ( t=10.43, P=<0.001). After 24, 48 and 72h of the HMGN5 gene was knockout, the survival rate of HepG2 hepatoma cells was lower than that of HL-7702 hepatoma cells (all P<0.05) and the apoptosis rate of hepatoma HepG2 cells was higher than that of liver HL-7702 cells [(18.63±1.76)%vs(1.81±0.21)%] ,the difference was statistically significant ( t=16.44, P<0.001). Conclusions:HMGN5 genes and proteins are highly expressed in the hepatocellular cancer tissues and HepG2 cells. HMGN5 gene plays an important role in the growth of hepatocellular cancer and can be used as a potential target of treatment for hepatocellular cancer.

Objective:To analyze the color Doppler flow imaging (CDFI) features of familial exudative vitreoretinopathy (FEVR) at different stages.Methods:A retrospective study. A total of 104 patients with 201 eyes from Department of Ophthalmology of Beijing Tongren Hospital who were hospitalized for fundus examination and diagnosed with FEVR from 2018 to 2022 were included. There were 69 male cases with 133 eyes and 35 female cases with 68 eyes. The age was ranged from 2 months to 11 years, with a mean age of 2.9 years. Fundus and CDFI examination were performed in both eyes. Fluorescein fundus angiography was performed in 72 cases (144 eyes). FEVR staging was conducted according to literature standards. The presence of avascular areas in the peripheral retina or abnormal retina neovascularization was stage 1; the presence of retinal neovascularization at the vitreoretinal interface in the avascular area was stage 2; partial retinal detachment without macula involvement was stage 3; partial retinal detachment involving the macula was stage 4; complete retinal detachment was stage 5. The CDFI ultrasound features of FEVR at different stages were analyzed. The CDFI image features of FEVR patients in different stages were observed.Results:Among the 104 patients, 97 (93.3%, 97/104) cases were binocular and 7 (6.7%, 7/104) cases were monocular. In 201 eyes, stages 1 to 5 of FEVR were 49 (24.4%, 49/201), 23 (11.4%, 23/201), 39 (19.4%, 39/201), 71 (35.3%, 71/201), and 19 (9.5%, 19/201) eyes, respectively. CDFI examination showed no abnormality or mild vitreous opacity in 49 eyes vitreous body at stage 1. Vitreous opacities were observed in all 23 eyes in stage 2, and the echo of the temporal ballwall was not smooth. In 39 eyes at stage 3, the anterior globular cluster echo in temporal peripheral eyes was observed in 17 eyes and partial retinal detachment was observed in 13 eyes. In 71 eyes at stage 4, 51 eyes had temporal or infratemporal retinal folds, and 20 eyes had temporal retinal detachment. All the 19 eyes in stage 5 had total retinal detachment, of which 15 eyes had closed "funnel-shaped" retinal detachment. Among the patients with retinal folds, 13 had bilateral folds, and the fellow eyes of the other 25 patients with unilateral folds all had vitreous opacity or clump echo in front of the temporal spherical wall. Blood flow signals could be detected on the retinal folds with Doppler imaging.Conclusions:The CDFI manifestations of FEVR patients at different stages have different characteristics. The possibility of FEVR should be considered when the temporal or infratemporal retinal folds of both eyes are present, as well as the retinal folds of one eye, the contralateral vitreous body opacity, or the anterior temporal peribulbar cluster echoes are present.

Sinisan is a classical prescription developed and applied by ancient medical experts and it is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Eastern Han Dynasty. Later physicians have modified this prescription based on this original one. The bibliometrics methods were used to analyze the key information and research trend of Sinisan. According to the inclusion and exclusion criteria, 69 pieces of effective data were extracted, involving 67 ancient traditional Chinese medicine (TCM) books. The results showed that the name, composition, and decocting methods of Sinisan in later generations were inherited from the original record in the Treatise on Cold Damage. The original plants of medicinal materials used in Sinisan are basically clear. We recommend Bupleuri Radix as the dried root of Bupleurem scorzonerifolium, Paeoniae Radix Alba as the dried root of Paeonia lactiflora, Aurantii Fructus as the dried fruit of Citrus aurantium, Glycyrrhizae Radix et Rhizoma as the dry root and rhizome of Glycyrrhiza uralensis. Raw materials of Bupleuri Radix and Paeoniae Radix Alba, Aurantii Fructus stir-fried with bran, and stir-fried Glycyrrhizae Radix et Rhizoma should be used for preparation of Sinisan. According to measurement system in the Han Dynasty, a bag of Sinisan is composed of 1.25 g Bupleuri Radix, 1.25 g Paeoniae Radix Alba, 1.25 g Aurantii Fructus, and 1.25 g Glycyrrhizae Radix et Rhizoma. The materials should be grounded into coarse powder and taken with a proper amount of rice soup, 3 times a day. Sinisan has the effects of regulating qi movement and harmonizing the liver and spleen. It can be used for treating reversal cold in limbs and cold damage. In modern clinical practice, Sinisan can be used to treat chronic gastritis, irritable bowel syndrome, and dyspepsia. The above research results provide scientific reference for the future research and development of Sinisan.

Houpo Sanwutang, included in the Catalogue of Ancient Classical Prescriptions (Second Batch), was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining, statistical analysis, and data processing, combined with modern articles, this study employed bibliometrics to investigate the historical origin, composition, decoction methods, clinical application, and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty, it is recommended that 110.4 g Magnolia Officinalis Cortex, 55.2 g Rhei Radix et Rhizoma, and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first, and 1 000 mL should be taken from the decocted liquid. Following this, Rhei Radix et Rhizoma should be added for further decoction, and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL, and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi, relieving stuffiness and fullness, removing food stagnation, and regulating bowels. It can be used in treating abdominal distending pain, guarding, constipation, and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach.

Qingfeitang, specialized in resolving phlegm to stop cough and producing fluid to moisten dryness, is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions (First Batch) published by the National Administration of Traditional Chinese Medicine (TCM) in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin, formula composition, herb origin, preparation methods, processing methods, clinical effect, and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study, a total of 43 pieces of effective data on relevant ancient literature, including 35 ancient TCM books, were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows: "Scutellariae Radix of 5.60 g, Platycodon grandiflora, Poria, Tangerine, Fritillaria, and Cortex Mori of 3.73 g respectively, Angelicae Sinensis Radix, Asparagi Radix, Gardeniae Fructus, Armeniacae Semen Amarum, and Ophiopogonis Radix of 2.61 g respectively, Schisandra of 1 g, and Glycyrrhizae Radix et Rhizoma of 1.12 g, and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water, with 3.37 g ginger and 6 g jujubae fructus, to 320 mL, and taken after a meal, three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness, specialized in treating cough, asthma, rash, and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system, used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

Objective:To analyze the time to reach full enteral feedings (TFEF) among preterm infants with gestational age (GA)<32 weeks admitted to the neonatal intensive care unit (NICU) of Chinese Neonatal Network (CHNN).Methods:This was a retrospective analysis based on the database from the CHNN 89 participating centers between January 1 st, 2019 and December 31 st, 2022. All 16 155 preterm infants with a GA <32 weeks and a birth weight <1 500 g, admitted to the NICU within 24 h after birth, hospitalization for at least 7 d and achieved full enteral feedings before discharge were included. According to the birth weight, these infants were divided into extremely low birth weight (ELBW) group and very low birth weight (VLBW) group. The practice characteristics of TFEF across different GA, the severity of neonatal admission, the NICU interventions before reaching full enteral feeding, and relevant neonatal diseases were described. Mann-Whitney U tests or Kruskal-Wallis H tests was used for comparison between groups. Results:Among the 16 155 preterm infants with a GA <32 weeks, 8 505 case (52.6%) were male. The TFEF in 3 374 cases of ELBW groups was 32 (22, 46) d, 351 cases (10.4%) with TFEF ≤2 weeks, 1 050 cases (31.1%) with TFEF >2-4 weeks, 964 cases (28.6%) with TFEF >4-6 weeks, and 1 009 cases (29.9%) with TFEF >6 weeks. The TFEF in 12 781 cases of VLBW group was 22 (15, 32) d, 439 cases (3.4%) with TFEF ≤1 week, 2 565 cases (20.1%) with TFEF >1-2 weeks, 5 526 cases (43.2%) with TFEF >2-4 weeks, and 4 251 cases (33.3%) with TFEF >4 weeks. The TFEF was 36(23, 52) d of 625 preterm infants at a GA ≤25 weeks and 20 (13, 28) d of 2 606 preterm infants at a GA 31 weeks. Inborn infants had a shorter TFEF than those outborn infants and the infants with breast-fed achieved shorter than formula and mixed feeding both in ELBW and VLBW groups (all P<0.001). The earlier enteral feeding started, the shorter TFEF will be both in ELBW and VLBW groups (both P<0.001). The TFEF of preterm infants who were treated before full enteral feeding like peripherally inserted central catheters, and blood transfusions and blood product providers were all longer than those who were not treated (all P<0.001). The TFEF of preterm infants with complications like hemodynamically significant patent ductus arteriosus, necrotizing enterocolitis, late onset sepsis, severe retinopathy of prematurity and bronchopulmonary dysplasia were all longer than those without (all P<0.001). Conclusions:The distribution of TFEF in VLBW and ELBW has a large difference. The TFEF of preterm infants varies with different GA, treatment measures and complications. Further quality improvement is required to shorten TFEF.
