This paper summarized Professor BU He's clinical experience in the integrative internal and external treatment of pediatric functional constipation. He believes that dysfunction of the spleen in transportation leads to impaired function of the sanjiao (三焦) and intestinal obstruction, which constitutes the core pathogenesis of pediatric functional constipation. The treatment emphasizes regulating the spleen and harmonizing the pivot, as well as unblocking the bowel and eliminating stagnation. An integrated approach combining internal and external therapies is advocated. Internally, Chinese herbal medicine, primarily Modified Sijunzi Decoction and Shaoyao Gancao Decoction (四君子汤合芍药甘草汤加减) is used to regulate the internal organs. Externally, pediatric tuina and moxibustion on qi interlocking are employed. Together, these methods fortify the spleen and facilitate transportation, restoring the smooth function of the sanjiao pivot, and ensuring intestinal patency, thereby relieving constipation.

ObjectiveTo explore the mechanism by which Zuoguiwan improves the pancreas development in the gestational diabetes mellitus (GDM) model by observing the effects of Zuoguiwan on the expression of key regulatory factors in different stages of pancreas development. MethodsPregnant Wistar rats were randomly assigned into blank, model, insulin detemir (20 U·kg-1) and Zuoguiwan (1.89 g·kg-1) groups (n=18). GDM was induced by peritoneal injection of streptozotocin on day 6.5 (E6.5d) in the embryonic stage, and the blank group was given an equal volume of sodium citrate buffer. The modeling performance was assessed by measuring the blood glucose of pregnant rats. Except the blank group and model group, pregnant rats in other groups were administrated with corresponding drugs from E9.5d to delivery. The random blood glucose of pregnant rats was monitored, and the embryos and offspring rats were measured for the length and weighed on E12.5d, E18.5d and day 21 after birth (B21d). The Lee's index of rats on B21d was calculated. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the fasting insulin (FINS) levels of B22d rats and the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) was calculated. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), total cholesterol (CHO), triglyceride (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL) in E18.5d pregnant rats and B22d offspring were determined. The pathological changes in the pancreas of E12.5d, E18.5d and B22d rats were observed by hematoxylin-eosin (HE) staining. Western blot was used to determine the protein levels of pancreatic duodenal homeobox 1 (Pdx1), pancreas-specific transcription factor 1a (Ptf1a), and sex-determining region Y-box protein 9 (Sox9) in the pancreas of E12.5d embryos, Pdx1, Nkx2 homeobox 2 (Nkx2.2), and hairy and enhancer of split-1 (Hes1) in the pancreas of E18.5d embryos, and Pdx1, v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (Mafa), and NK transcription factor-related homeobox gene family 6 locus 1 (Nkx6.1) in the pancreas of B22d rats. ResultsCompared with the blank group, the model group showed elevated blood glucose levels in pregnant rats on B0d, E9.5d, E12.5d, E15.5d, and E18.5d (P<0.05, P<0.01), decreased body weight and body length (P<0.01) and increased Lee's index in the offspring. In addition, the B22d offspring showed rising levels of FBG, FINS, HOMA-IR, AST, and TG (P<0.01), a declined level of HDL (P<0.01), and pancreatic acinous cells with edema and loose arrangement. The pregnant rats on E18.5d exhibited raised levels of ALT, AST, and TG (P<0.05, P<0.01) in the pancreas and a declined level of HDL (P<0.05). The E12.5d embryos showed up-regulated protein levels of Pdx1, Sox9, and Ptf1a in the pancreas (P<0.01) and the E18.5d embryos exhibited down-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas (P<0.01). The protein levels of Pdx1, Nkx6.1, and Mafa in the pancreas of B22d offspring were down-regulated (P<0.01). Compared with the model group, the insulin group exhibited lowered blood glucose in pregnant rats on B0d, E15.5d, and E18.5d (P<0.05, P<0.01). The offspring in all treatment groups showcased increased body weight and body length (P<0.01) and decreased Lee's index. The B22d offspring exhibited declined levels of FBG, FINS, and HOMA-IR in the insulin group (P<0.01) and lowered levels of FBG and HOMA-IR in the Zuoguiwan group (P<0.01). The B22d offspring in all the treatment groups showed reduced levels of ALT, AST, TBIL, CHO, TG, and LDL, a raised level of HDL, and alleviated edema of pancreatic acinous cells. The pregnant rats on E18.5d demonstrated declined levels of TG and ALT (P<0.05, P<0.01) and an elevated level of HDL (P<0.05). The pancreas of E12.5d embryos presented down-regulated protein levels of Pdx1 and Sox9 and an up-regulated protein level of Ptf1a in the insulin group (P<0.05). The pancreas of E12.5d embryos in the Zuoguiwan group presented down-regulated protein levels of Pdx1, Sox9, and Ptf1a (P<0.01). All the treatment groups showed up-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas of E18.5d embryos (P<0.01) and Pdx1, Nkx6.1, and Mafa in the pancreas of B22d embryos (P<0.05, P<0.01). ConclusionZuoguiwan can promote the growth and development and ameliorate the pathological changes in the pancreas of the offspring of GDM model by regulating the expression of Pdx1 pathway-related regulatory factors in different stages of pancreas development.

OBJECTIVE To establish the characteristic chromatogram of Chaenomeles sinensis, determine the contents of rutin, hyperin and quercitrin, and to identify C. sinensis and C. speciosa. METHODS HPLC method was performed on Agilent 5 TC-C18 column, with acetonitrile-0.2% formic acid solution as the mobile phase for gradient elution, at the flow rate of 1.0 mL/min. The column temperature was 30 ℃ . The detection wavelength was 330 nm in characteristic chromatogram and 350 nm in content determination. The characteristic chromatogram of C. sinensis was established and similarity was evaluated by the Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012 edition). Hierarchical cluster analysis of 15 batches of C. sinensis (S1-S15) was performed by using SPSS 23.0 software. The contents of 3 flavones in 15 batches of C. sinensis and 7 batches of C. speciosa (S16-S22) were determined, while their characteristic chromatograms were compared. RESULTS The similarities of the characteristic chromatogram for 15 batches of C. sinensis ranged from 0.783 to 0.969, and 11 characteristic peaks were confirmed. Four constituents were identified as chlorogenic acid, rutin, hyperin and quercitrin. The medicinal materials in 15 batches of C. sinensis could be divided into 2 categories: S5-S8 were one category, and the others belonged to one category. The characteristic chromatogram of C. sinensis was obviously different from C. speciosa. The contents of rutin, hyperin and quercitrin in 15 batches of C. sinensis were 48.99-294.45, 3.49-102.55, 31.98-149.49 μg/g, respectively. The content of rutin in C. speciosa was lower than that in C. sinensis. None of hyperin (except for S20) and quercitrin were detected in C. speciosa. CONCLUSIONS The characteristic chromatogram and the method for content determination of 3 flavones in C. sinensis are established successfully and can be used for the quality control of C. sinensis and its identification from C. speciosa.

OBJECTIVE To investigate the inhibitory effects of Ginkgo biloba extract (GBE) on renal inflammation in diabetic nephropathy (DN) model mice, and its potential mechanism. METHODS KK/Ay mice were fed with high fat and high sugar to induce DN model. They were divided into model group, positive control group [metformin 200 mg/(kg·d)], GBE low-dose and high-dose groups [100, 200 mg/(kg·d)], with 6 mice in each group. Six C57BL/6J mice were fed with a regular diet as the control group. Administration groups were given relevant liquid intragastrically, control group and model group were given constant volume of normal saline intragastrically, once a day, for 8 consecutive weeks. The body weight, fasting blood glucose, 24-hour food intake, 24-hour urine output, monocyte chemoattractant protein-1 (MCP-1), interleukin-12 (IL-12), IL-10, advanced glycation end products (AGEs), blood urea nitrogen (BUN) and serum creatinine (Scr) of mice were measured, and the ratio of bilateral kidneys to body weight was also calculated. The pathological injury and fibrotic changes of the renal cortex were observed, and the expressions of macrophage polarization marker proteins [type M1: inducible nitric oxide synthase (iNOS); type M2: arginase-1 (Arg-1)] and AGEs-the receptor of advanced glycation end products (RAGE)/Ras homolog gene pharm_chenjing@163.com family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) signaling pathway-related proteins were determined in renal cortex. RESULTS Compared with the model group, the symptoms such as renal cortical hyperplasia, vacuoles, infiltration of inflammatory cells, and renal cortical fibrosis had been improved in GBE low-dose and high-dose groups; body weight, serum level of IL-10, the expression of Arg-1 in the renal cortex were significantly higher than model group (P< 0.01); fasting blood glucose, 24-hour food intake, 24-hour urine output, serum levels of MCP-1, IL-12, BUN, Scr and AGEs, the ratio of bilateral kidneys to body weight, renal injury score, the proportion of renal interstitial fibrosis, the protein expressions of iNOS, RAGE, RhoA and ROCK1 (except for GBE low-dose group) in renal cortex were significantly lower than model group (P<0.01). CONCLUSIONS GBE could improve kidney damage and alleviate inflammatory response in DN model mice, the mechanism of which may be related to inhibiting the AGEs-RAGE/RhoA/ROCK signaling pathway and regulating macrophage polarization.

【Objective】 To investigate the frequency of platelet antibodies in voluntary blood donors and patients in Zhongshan, Guangdong Province, and to study the specificity and cross-matching of platelet antibodies. 【Methods】 Platelet antibodies of blood donors and patients were screened by solid-phase immunoadsorption (SPIA), rechecked by flow cytometry (FCM), and antibody specificity was identified by PakPlus enzyme immunoassay, and platelet cross-matching was simulated by SPIA. 【Results】 A total of 1 049 blood donor samples and 598 patient samples were tested, with 6 (0.57%) and 49 (8.19%) samples positive for SPIA,respectively(P<0.05); In SPIA positive samples, the positive concordance rate of FCM in blood donors and patients was 100% vs 95%, and that of enzyme immunoassay was 100% vs 88%. Among the initial screening positive samples of blood donors, 5 were anti-HLA Ⅰ antibodies, accounting for 83%, and 1 was anti CD36 antibody, accounting for 17%, with an incidence rate of 0.10%. Among the 14 samples of enzyme immunoassay positive patients, 2 were anti-GP Ⅱb/Ⅲa, 1 was anti-GP Ⅱa/Ⅱa, 8 were anti HLA Ⅰ, and 3 were mixed antibodies (HLA Ⅰ, GP Ⅱb/Ⅲa, GP Ⅰa/Ⅱa). According to the types of antibodies, HLA Ⅰ antibodies were the most common, accounting for 65% (11/17), followed by HPA related anti GP, accounting for 35% (6/17). The majority of patients had a platelet antibody positive typing rate below 30%, accounting for 71.4% (10/14). 【Conclusions】 The positive rate of platelet antibody of patients in Zhongshan area is significantly higher than that of voluntary blood donors, and most of them are anti-HLA Ⅰ and anti-GP, and the incidence of anti-CD36 is extremely low. Therefore, it is necessary to establish a known platelet antigen donor bank, and at the same time, carry out platelet antibody testing and matching of patients, which is helpful to solve the issue of platelet transfusion refractoriness.

Consumptive thirst is widely discussed in Huangdi Neijing and it is classified as a"strange disease"in Suwen·Strange Diseases Treatise,which reflects the intractable nature of consumptive thirst.This paper explores and analyzes consumptive thirst based on the core concept in Huangdi Neijing.First,this paper approaches the subject through the use of image thinking method from Huangdi Neijing,recognizing that consumptive thirst can lead to changes in the internal climate of the human body.Then,guided by the theories of essence and qi,yin and yang,and the five elements in Huangdi Neijing,it deconstructs and analyzes the causes of these changes and the laws of qi transformation.It points out that the changing climate of consumptive thirst is characterized by"heat symptoms".The main cause of"heat symptoms"is spleen deficiency and excessive dampness,and its qi transformation law is the heat transformation of Shaoyin.The intractable nature of consumptive thirst is mainly reflected in the uncontrolled"heat symptoms"caused by the imbalance of the five elements.Based on the understanding of the heat symptoms of consumptive thirst,this paper proposes a treatment strategy for preventing the disease by resolving dampness and regulating the spleen,harmonizing kidney qi to prevent progression,and balancing yin and yang to treat chronic and recalcitrant conditions.The aim is to provide a reference for optimizing the treatment of consumptive thirst.

Rheumatoid arthritis (RA) is an autoimmune disease with a complex etiology. Monocyte-derived macrophages (MDMs) infiltration are associated with RA severity. We have reported the deletion of G-protein-coupled receptor kinase 2 (GRK2) reprograms macrophages toward an anti-inflammatory phenotype by recovering G-protein-coupled receptor signaling. However, as more GRK2-interacting proteins were discovered, the GRK2 interactome mechanisms in RA have been understudied. Thus, in the collagen-induced arthritis mouse model, we performed genetic GRK2 deletion using GRK2f/fLyz2-Cre+/- mice. Synovial inflammation and M1 polarization were improved in GRK2f/fLyz2-Cre+/- mice. Supporting experiments with RNA-seq and dual-luciferase reporter assays identified peroxisome proliferator-activated receptor γ (PPARγ) as a new GRK2-interacting protein. We further confirmed that fms-related tyrosine kinase 1 (Flt-1), which promoted macrophage migration to induce angiogenesis, was inhibited by GRK2-PPARγ signaling. Mechanistically, excess GRK2 membrane recruitment in CIA MDMs reduced the activation of PPARγ ligand-binding domain and enhanced Flt-1 transcription. Furthermore, the treatment of mice with GRK2 activity inhibitor resulted in significantly diminished CIA pathology, Flt-1+ macrophages induced-synovial inflammation, and angiogenesis. Altogether, we anticipate to facilitate the elucidation of previously unappreciated details of GRK2-specific intracellular signaling. Targeting GRK2 activity is a viable strategy to inhibit MDMs infiltration, affording a distinct way to control joint inflammation and angiogenesis of RA.
