Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases， originated from the Yan's Prescriptions to Aid the Living （Yan Shi Ji Sheng Fang） written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix， Cirsii Herba， Talcum， Akebiae Caulis， Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， Angelicae Sinensis Radix， Gardeniae Fructus， and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding， draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living， while dispute has emerged during the inheritance of this prescription. In this study， the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms： powder and decoction. According to the measurement system in the Song Dynasty， the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder， 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba， Talcum， Akebiae Caulis， stir-fried Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， wine-processed Angelicae Sinensis Radix， stir-fried Gardeniae Fructus， and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue， the decoction was taken warm before meals， 3 times a day （i.e.， 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time）. In the preparation of Xiaoji Yinzi decoction， 20.65 g each of the above 10 herbs are used， with stir-fried Typhae Pollen， wine-processed Angelica Sinensis Radix， stir-fired Gardeniae Fructus， stir-fired Glycyrrhizae Radix et Rhizoma， and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer， which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice， Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

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.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Zhigancao Tang （also known as Fumaitang） is a classic formula for treating "intermittent pulse and palpitations" and is widely used in clinical practice. Sanjia Fumaitang， included in the Catalogue of Ancient Classical Formulas （First Batch） published by the National Administration of Traditional Chinese Medicine of China in 2018， is derived from this formula. This paper employed bibliometric methods to comprehensively investigate and summarize the historical evolution， drug composition， herb origins and preparation， prescription meanings， and ancient and modern applications of Zhigancao Tang， analyzed the composition and usage of Zhigancao Tang， and discussed the reasons and applications of the "Fumaitang" variants created by Wu Jutong. A total of 47 valid pieces of data from 38 ancient texts were included. Results showe that Zhigancao Tang originates from the Treatise on Cold Damage （Shang Han Lun）， and the name "Fumaitang" is also recorded in the formula's description. Converted to modern measurements from the Han dynasty system， the recommended preparation for Zhigancao Tang includes 55.2 g of fried Glycyrrhizae Radix et Rhizoma， 41.4 g of Cinnamomi Ramulus， 27.6 g of Ginseng Radix et Rhizoma， 220 g of fresh Rehmannia glutinosa， 27.6 g of Asini Corii Colla， 53 g of Ophiopogonis Radix， 45 g of Cannabis Fructus， and 90 g of Jujubae Fructus. All herbs should be decocted with 1 400 mL of yellow rice wine and 1 600 mL of water until 600 mL. Once the Asini Corii Colla is fully dissolved， the decoction should be taken warm at a dosage of 200 mL， three times a day. Zhigancao Tang is effective for replenishing Qi， warming Yang， nourishing Yin， and nourishing blood and is primarily used to treat “intermittent pulse and palpitations” caused by deficiencies in heart Yin and Yang， as well as malnutrition of the heart meridian and conditions like lung atrophy. Modern applications mainly focus on cardiovascular and cerebrovascular diseases， including arrhythmias， coronary heart disease， and premature ventricular contractions. The findings from this research provide a reference for the further development of Zhigancao Tang.

Objective To investigate the effect of visceral fat area (VFA) on perioperative related indi-cators and short-term prognosis of patients with colorectal cancer (CRC).Methods Clinical data of 102 pa-tients who underwent laparoscopic radical surgery for CRC in the First Affiliated Hospital of Baotou Medical College from September 2020 to August 2023 were retrospectively analyzed.All patients underwent preopera-tive abdominal CT examination,and the transverse CT images at the level of the third lumbar vertebra (L3) were selected.VFA was measured using Slice-O-Matic software,and patients were divided into the high VFA group (VFA≥100 cm2) and the low VFA group (VFA<100 cm2) based on the measurement results.Clinical data,patho-logical data,surgical data,postoperative complications,and perioperative coagulation and inflammation indicators were collected.Results Compared with the low VFA group,the high VFA group had higher BMI,longer hospital stay,greater intraoperative blood loss,and fewer lymph node dissections (P<0.05).The WBC and PCT lev-els before and after surgery in the high VFA group were higher than those in the low VFA group (P<0.05). Compared with preoperative levels,WBC,C-reactive protein (CRP),PCT,plasma prothrombin time (PT), plasma fibrinogen (FIB),and international standardized ratio (INR) increased and PLT decreased in both groups after surgery,the differences were statistically significance (P<0.05);Compared with preoperative conditions,the activated partial prothrombin time (APTT) in the high VFA group and the thrombin time (TT) decreased in the low VFA group decreased after surgery,the differences were statistically significant (P<0.05).The total incidence of postoperative complications (21.2％) and the incidence of incision compli-cations (15.4％) in the high VFA group were higher than that in the low VFA group (4.0％,2.0％),the differences were statistically significant (P<0.05).Conclusion Colorectal cancer patients with high VFA during the perioperative period exhibit higher levels of inflammation indicators and poorer prognosis.

Objective The equilibrium solubility and oil-water partition coefficient of caffeic acid in different pH environments were determined,and its biopharmaceutical classification system(BCS)classification was speculated.The dissolution curve of caffeic acid tablets was determined,and the above parameters were substituted into the rat PBPK model for modeling.Gastroplus software was used to predict the in vitro and in vivo correlation of caffeic acid tablets.Methods Quantitative analysis of caffeic acid was performed by a high-performance liquid chromatography in this research,the chromatographic column was Agilent Eclipse Plus C18(4.6 mm×250 mm,5 μm),the mobile phase was 0.32%glacial acetic acid solution-methanol(70∶30),the flow rate was 1.0 mL·min-1,the detection wavelength was 323 nm,the column temperature was 25℃,the injection volume was 10 μL.The equilibrium solubility,solubility volume(DSV)and oil-water partition coefficient(P)of caffeic acid in different pH buffers were measured by the shake flask method and n-octanol-water system,and its BCS classification was speculated.The dissolution curves of caffeic acid tablets in water,pH1.2,pH4.5 and pH6.8 were determined.The Z-Factor values of these dissolution curves were analyzed using Gastroplus software.The relevant parameters were substituted into the physiological pharmacokinetic(PBPK)model of rats to simulate the in vivo pharmacokinetic(PK)curve of rats.Compared with the measured PK curve that was reported previously,the correlation between in vivo and in vitro was speculated.Results The equilibrium solubility of caffeic acid in pH1.2,pH4.5 and pH6.8 were 0.676,1.266 and 4.624 mg·L-1,and the DSV were 443 787,236 967 and 64 879 mL,which showed that caffeic acid was an insoluble drug which had a strong pH dependence in dissolution;The oil-water partition coefficients(P)of caffeic acid in water,pH1.2 buffer,pH4.5 buffer and pH6.8 buffer were 4.33(logP=0.64),28.87(logP=1.46),19.77(logP=1.30)and 0.28(logP=-0.56),which indicated that caffeic acid was a BCS Ⅱ drug with high permeability.The results of the Cmax,tmax and AUC of caffeic acid in rats obtained by a software simulation was 0.358 μg·mL-1,0.39 h and 0.320 μg·h-1·mL-1,which was basically matched with the results[Cmax∶(0.250±0.037)μg·mL-1、tmax∶(0.33±0.12)h、AUC∶(0.303±0.024)μg·h-1·mL-1]that reported previously,so was the PK curves.Conclusion Caffeic acid is a drug with low solubility and high permeability.It is speculated that caffeic acid is a BCS Ⅱ drug,and its tablets show a high correlation in vivo and in vitro in rats.

ObjectiveBased on serum pharmacochemistry and ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） the transitional components in the serum of rats after intragastric administration of water extract of Alismatis Rhizoma（AR）and salt-processed Alismatis Rhizoma（SAR） were compared. MethodSD rats were randomly divided into blank group, AR group（10 g·kg^-1） and SAR group（10 g·kg^-1）, 3 rats in each group, the administration groups were given AR and SAR aqueous extracts by gavage, respectively, and the blank group was given an equal volume of drinking water by gavage once in the morning and once in the evening, for 3 consecutive days. Sixty minutes after the last administration, blood was collected from the eye orbits, and the serum samples were prepared. The serum samples were prepared on an ACQUITY UPLC BEH C18 column（2.1 mm×50 mm, 1.7 μm） with the mobile phase of acetonitrile（A）-0.1% formic acid aqueous solution（B） in a gradient elution（0-10 min, 10%-50% A; 10-27 min, 50%-95%A; 27-27.1 min, 95%-10% A; 27.1-30 min, 10%A）, the data were collected at a flow rate of 0.3 mL·min^-1 in positive ion mode with a scanning range of m/z 100-1 200. Based on the self-constructed chemical composition library of AR, the total ion flow diagrams and secondary MS fragmentation information of the aqueous extracts of AR and SAR, as well as the administered serum and the blank serum, were compared with each other by UNIFI 1.9.2, so as to deduce the possible blood-migrating constituents and their cleavage patterns in the aqueous extracts, and the response intensity ratios of each chemical component were calculated before and after processing. ResultA total of 20 components, including 5 prototypical components and 15 metabolites, were analyzed and deduced from the serum of rats given aqueous extract of AR. And 14 components, including 5 prototypical components and 9 metabolites, were analyzed and deduced from the serum of rats given aqueous extract of SAR. Of these, 13 components were common to both of them, including 5 prototypical components and 8 metabolites. The 5 prototypical components were 16-oxoalisol A, alisol A 24-acetate, alisol A, alisol B and alisol C. The metabolites were mainly involved in phase Ⅰ metabolism（oxidation） and phase Ⅱ metabolism（glucuronidation）. There was a big change in the intensity of response of the common components before and after salt-processing, and the response intensities of the prototypical components, 16-oxoalisol A, alisol B and alisol C, were elevated, while the type and response intensity of metabolites were generally decreased, and it was hypothesized that the metabolic rate of terpenoids might be slowed down after salt-processing of AR, so that the blood-migrating constituents could participate in the metabolism of the body more in the form of prototypes. ConclusionSalt-processing of AR may promote the absorption of prototypical components into the blood by slowing down the metabolic rate of terpenoids, which can provide support for the research on material basis of AR and SAR.

Objective:To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women.Methods:The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women.Results:For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% ( P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m 2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m 2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions:Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m 2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

ObjectiveTo evaluate the pharmacological effect of Alismatis Rhizoma （AR） and its processed product on rats with edema of kidney Yin deficiency and explore the mechanism. MethodA total of 42 male SPF SD rats were randomized into normal group （equivalent volume of distilled water）， model group （equivalent volume of distilled water）， positive medicine Liuwei Diguangwan group （1.4 g·kg^-1）， low- and high-dose AR groups （1， 4 g·kg^-1， respectively）， and low- and high-dose salt-processed AR （SAR） groups （1， 4 g·kg^-1， respectively）， with six rats in each group. Adriamycin （tail vein injection） and thyroxine （gavage） were used to induce edema of kidney Yin deficiency in rats except the normal group. The administration lasted 4 weeks for all the groups. After the last administration， histopathological changes of rat kidneys were observed based on hematoxylin-eosin （HE） staining. Serum content of triiodothyronine （T₃）， thyroxine （T₄）， follicle-stimulating hormone （FSH）， and testosterone （T） was determined by radioimmunoassay， and serum content of creatinine （CREA）， urea （UREA），cholesterol （CHOL） and triglyceride （TG） by automatic biochemical analyser. The levels of gonadotropin-releasing hormone （GnRH）， cyclic adenosine monophosphate （cAMP）， and cyclic guanosine monophosphate （cGMP） in plasma were measured by enzyme-linked immunosorbent assay （ELISA）， and the expression of aquaporin（AQP）-1 and AQP-2 and the transcription of mRNA in kidney were measured by immunohistochemistry and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）， respectively. ResultCompared with normal group， the rats in model group showed decrease in body mass and urine volume （P<0.01）， increase in water consumption （P<0.05）， infiltration of a large number of inflammatory cells and fibrous tissue proliferation in the kidney， rise of the expression and transcript levels of T₃， T₄， cAMP/cGMP， CREA， FSH， AQP-1， and AQP-2 （P<0.01）， the contents of CHOL and TG were significantly increased （P<0.05）， and reduction in the levels of GnRH and T （P<0.01）. Body mass increased in both the low- and high- dose groups of AR and SAR compared with that in model group， with significant differences between the low-dose AR group and the low-dose SAR group （P<0.01）. Moreover， compared with model group， low- and high-dose AR and SAR insignificantly increased the urine volume of rats， reduced the inflammatory cells in kidney tissues， significantly decreased the levels of T₄， cAMP/cGMP， UREA， CREA， FSH， CHOL and TG in serum （P<0.05，P<0.01）， and elevated the level of GnRH （P<0.01）， high-dose AR， low- and high-dose SAR significantly lowered the transcription levels of AQP-1 and AQP-2 mRNA in the kidneys of rats （P<0.01）. ConclusionBoth AR and SAR alleviated the edema of kidney Yin deficiency in rats by down-regulating the expression of AQP-1 and AQP-2 and correcting the hypothalamic-pituitary-gonadal （HPG） axis disorder.
