ABSTRACT
This article summarizes the experience of Professor ZHANG Boli in the staged treatment of very early onset inflammatory bowel disease （VEO-IBD）. Grounded in the theory of “similar diseases and syndromes of damp-turbidity-phlegm-rheum”， it is believed that dampness and turbidity are crucial pathogenic factors in VEO-IBD. During the acute phase， the core pathogenesis centers on the accumulation of turbid toxins in the intestines. The treatment focuses on dispelling dampness and clearing turbidity to eliminate turbid toxins， while also regulating the flow of qi and nourishing the spleen and kidney. During the remission phase， the core pathogenesis involves spleen and kidney deficiency， which is treated by invigorating the spleen and warming the kidney to strengthen the body resistance. Additionally， promoting blood circulation and eliminating stasis is integrated throughout the treatment process. Medications are chosen to be mild and gentle， emphasizing balance and harmony， and attention is given to the methods of administration and psychological well-being， ensuring comprehensive care for both body and mind.
ABSTRACT
The global coronavirus disease 2019 (COVID-19) pandemic has had a massive impact on global social and economic development and human health. By combining traditional Chinese medicine (TCM) with modern medicine, the Chinese government has protected public health by supporting all phases of COVID-19 prevention and treatment, including community prevention, clinical treatment, control of disease progression, and promotion of recovery. Modern medicine focuses on viruses, while TCM focuses on differential diagnosis of patterns associated with viral infection of the body and recommends the use of TCM decoctions for differential treatment. This differential diagnosis and treatment approach, with its profoundly empirical nature and holistic view, endows TCM with an accessibility advantage and high application value for dealing with COVID-19. Here, we summarize the advantage of and evidence for TCM use in COVID-19 prevention and treatment to draw attention to the scientific value and accessibility advantage of TCM and to promote the use of TCM in response to public health emergencies.

Activation of the heart normally begins in the sinoatrial node (SAN). Electrical impulses spontaneously released by SAN pacemaker cells (SANPCs) trigger the contraction of the heart. However, the cellular nature of SANPCs remains controversial. Here, we report that SANPCs exhibit glutamatergic neuron-like properties. By comparing the single-cell transcriptome of SANPCs with that of cells from primary visual cortex in mouse, we found that SANPCs co-clustered with cortical neurons. Tissue and cellular imaging confirmed that SANPCs contained key elements of glutamatergic neurotransmitter system, expressing genes encoding glutamate synthesis pathway (Gls), ionotropic and metabotropic glutamate receptors (Grina, Gria3, Grm1 and Grm5), and glutamate transporters (Slc17a7). SANPCs highly expressed cell markers of glutamatergic neurons (Snap25 and Slc17a7), whereas Gad1, a marker of GABAergic neurons, was negative. Functional studies revealed that inhibition of glutamate receptors or transporters reduced spontaneous pacing frequency of isolated SAN tissues and spontaneous Ca
ABSTRACT
Skin photoaging is caused by long-term exposure to sunlight. It is a kind of exogenous aging and one of the important causes of skin aging. The main symptoms include dry skin, roughness, sagging, wrinkles and localized pigmentation. There are diverse and complex mechanisms for causing skin photoaging, mainly involving oxidative stress, apoptosis, the role of matrix metalloproteinases, inflammatory reactions. The prevention and treatment methods of skin photoaging mainly include sunscreens, antioxidants and anti-inflammatory preparations. In recent years, the prevention and improvement of skin photoaging have become hotspots in the world. Therefore, the development of drugs with a defined anti-photoaging effect and clear anti-photoaging mechanism is urgent. Clinically, although retinoic acid and other drugs can alleviate skin photoaging, long-term use can cause side effects on central nervous system, and most of them have a strong irritation and damage to the skin. Traditional Chinese medicine(TCM) has the advantages of natural material, stable action, less toxic and side effects; furthermore, TCM and its compound have a long history in curative application, with a unique effect. This paper explores the anti-skin photoaging mechanism of TCM in recent years, its modern application and study progress, in order to provide some reference for exploring the mechanism and prevention of skin photoaging.

ABSTRACT
Objective By analysis oflateralepicondylitis patients MRI features to explore the lateralepicondylitis namedrationality and authorized its opinions for the ninth edition surgery textbook. Methods Cochrane's systematic review methods were used to retrieve the literature about lateralepi-condylitis patients MRI features fromCochrane Library, Medline, OVID, EMBASE, Chinese biomedical literature database (CBM), VIP, CNKI, Wan fang digital journals, and totally 31 articles were reviewed. 13 articles met the inclusion criteria for the lateral epicondyle of humerus elbow in patients with MRI findings. In accordance with the case-control data RevMan 5.0 software was used for Meta analysis withodds ratio (OR) as count data statistics. Interval estimation wasmade of 95% confidence interval (CI). When the datacannot be performed Meta analysis, only qualitative analysis was made. Results 13 studies met the inclusion criteria, including 315 ipsilateralelbows (5 patients with bilateral disease, 305 patients with unilateral disease) and 169 asymptomatic side of the elbow (98 cases of patients with the contralateral elbow, 71 cases of healthy volunteers). The results of Meta analysis suggested that pa-tients and healthy volunteers of elbow MRI showed statistically significance [OR=88.55, 95%CI=(29.20, 268.57)]. Between ipsilateral elbow and contra lateral of elbow MRI showed statistically significance [OR=80.17, 95%CI=(21.53, 298.59)]. MRI analysis showed that in addition to signs of extensor tendon injury, the elbow was also widely associated with other changes, such as radial collateral ligament in-jury, bone marrow edema, joint effusion, tendon tear, and elbows muscle edema. Conclusion Through MRI findings,the maln pathological changes of the so-called lateralepicondyliti-saremalnly for total ex-tensor tendon and adjacent tissue of chronic injury, Naming the current external humeral epicondylitis is unreasonable. Therefore, periarthritis of lateral epicondyle of humerus seems to be the best appropri-ate term to be usedwhenthe ninth edition surgery textbooksisauthorized.
ABSTRACT
Background Corneal transplantation is the most reliable and effective means to treat the corneal blindness in the clinical,immune rejection is a major cause of corneal graft failure after the keratoplasty.Objective This study aimed to investigate the role of Tim-1 in the immune reaction following corneal transplantation in rats.Methods Forty clean female Wistar rats were randomized into normal control group,autologous corneal transplantation group and allogeneic corneal transplantation group.Penetrating corneal transplantation was performed with the Wistar rat donors and Wistar rat receipts in the autologous corneal transplantation group,while with the SD rat donors and Wistar rat receipts in the allogeneic corneal transplantation group.The corneal graft diameter was 3.5 mm and the plant bed diameter was 3.0 mm.The inflammatory response of the grafts was examined under the slit lamp microscope 7 days and 14 days after operation and scored based on the criteria of Larkin.Rejection index (RI),mean survival time and survival rate were calculated.The histopathological examination was performed 7 days and 14 days after surgery to evaluate the inflammatory manifestation,and the expressions of Tim-1 protein and mRNA were assayed by immnunochemistry and real-time fluorescence quantitative PCR (RT-qPCR)in the time points mentioned above.Results Mild edema of the grafts were found 7 days after operation in both the autologous corneal transplantation group and the allogeneic corneal transplantation group.In postoperative 14 days,the grafts were clear in the autologous corneal transplantation group,but the thickening,neovacularization and cloudy of the grafts were exhibited in the allogeneic corneal transplantation group.The survival rate of the grafts was 100％ in the autologous corneal transplantation group and that of the allogeneic corneal transplantation group was 0 with the survival time of (9.8±1.2) days.Histopathological examination revealed the stromal infiltration of inflammatory cells in both the autologous and allogeneic corneal transplantation groups in the seventh day,however,the inflammatory cells were obvious decreased in the autologous group but increased in the allogeneic corneal transplantation group in the fourteenth day.Immunochemistry showed a gradually declined positive cells for Tim-1 protein in the autologous corneal transplantation group,but the positive cells were exactly elevated in the allogeneic corneal transplantation group from 7 days through 14 days after operation;While only few positive cells were seen in the normal control group.The expression levels of Tim-1 mRNA in the grafts were 1.24 ± 0.03,5.85 ± 0.08 and 6.54 ± 0.20 in the normal control group,autologous corneal transplantation group and that of the allogeneic corneal transplantation group,respectively,in the seventh day,and in the fourteen day after operation,the expression level declined to 1.54 ±0.10 in the autologous corneal transplantation group and elevated to 8.62±0.24 in the allogeneic corneal transplantation group,showing significant differences among the different groups and various time points (Fgroup =3 277.590,P =0.000 ; Ftime =136.000,P =0.000).Conclusions Tim-1 may play an important role not only in the inflammatory response but also in the rejection reaction of the corneal transplantation.
ABSTRACT
Aortic valve calcification is a common disease in the elderly, but its cellular and molecular mechanisms are not clear. In order to verify the hypothesis that Wnt/β-catenin signaling pathway is involved in the process of calcification of aortic valve, porcine aortic valve interstitial cells (VICs) were isolated, cultured and stimulated with oxidized low density lipoprotein (ox-LDL) for 48 h to induce the differentiation of VICs into osteoblast-like cells. The key proteins and genes of Wnt/β-catenin signaling pathway, such as glycogen synthase kinase 3β (GSK-3β) and β-catenin, were detected by using Western blotting and real-time polymerase chain reaction (PCR). The results showed that the VICs managed to differentiate into osteoblast-like cells after the stimulation with ox-LDL and the levels of proteins and genes of GSK-3β and β-catenin were increased significantly in VICs after stimulation for 48 h (P<0.05). It is suggested that Wnt/β-catenin signaling pathway may play a key role in the differentiation of VICs into osteoblast-like cells and make great contribution to aortic valve calcification.

OBJECTIVE@#To investigate the interference and expression of human glial cell line-derived neurotrophic factor (hGDNF) and soluble TNF alpha (sTNFR I) receptor genes in neural stem cells and to evaluate the roles of these proteins in the genetic treatment of spinal cord injury.@*METHODS@#Full-length of GDNF cDNA (558 bp) and sTNFR I cDNA (504 bp) were inserted into the early 1 region of adenovirus genomic DNA respectively and were immediated by the human cytomegalovirus (gene promoter/enhancer). These adenoviruses were propagated in HEK293 cells via homologous recombination for 7-10 days in vivo, then they were used to infect human neural stem cells. The infection and expression of gene were tested under immunofluorescence, ELISA and Western-blot after 48 hours.@*RESULTS@#Almost all the cultured cells showed the nestin immunofluorescence positive staining, which was the characteristics of neural stem cell. A great quantity of EGFP and RFP were observed in neural stem cells, which indicated the expression of GDNF and sTNFR I. After transfection of GDNF and sTNFR I genes, many neural stem cells show GFAP and tubulin immunofluorescence positive staining, which meant that most neural stem cells differentiated into neuron at that condition.@*CONCLUSIONS@#The infective efficiency of adenovirus is greatly acceptable to neural stem cell, thus adenovirus provide a useful vector for exogenous GDNF and sTNFR I genes expressing in neural stem cells, which is useful for differentiation of neural stem cell.
