Objective To observe the clinical efficacy of Shen Shuai Ⅱ Granules combined with integrated Western medicine therapy in patients with primary chronic kidney disease(CKD)in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis,and its effects on expression of serum autophagy related proteins.Methods Totally 88 patients were randomly divided into treatment group and control group,with 44 cases in each group.Both groups were given an integrated Western medicine therapy.On this basis,the treatment group was given Shen Shuai Ⅱ Granules,while the control group was given Shen Shuai Ⅱ placebo,1 bag at a time,twice a day,orally.The treatment for both groups lasted for 24 weeks.The clinical efficacy of the two groups was observed.The TCM symptom scores,serum creatinine(Scr),blood urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),blood phosphorus(P3-),parathyroid hormone(PTH),and 24-hour urinary protein quantification(24 UPro)before and after treatment were compared in the two groups.The serum levels of autophagy related protein Beclin-1,Atg7,and LC3-Ⅱ were detected by ELISA before and after treatment in the two groups.Safety indexes of both groups were monitored.Results During the treatment,4 cases fell off in the treatment group and 4 cases in the control group.The total effective rate in the treatment group was 55％(22/40),while that in the control group was 30％(12/40).The therapeutic effect in the treatment group was better than that in the control group(P<0.01).Compared with before treatment,the TCM symptom scores in the treatment group decreased after treatment(P<0.01),the levels of Scr,BUN,UA,P3-,PTH,and 24 UPro decreased(P<0.05,P<0.01),while eGFR increased(P<0.01).The levels of Scr in the control group increased(P<0.05),while eGFR decreased(P<0.01).After treatment,the treatment group had lower various TCM symptom scores,Scr,BUN,UA,P3-,PTH,and 24 UPro levels than the control group(P<0.01,P<0.05),and higher eGFR than the control group(P<0.01).Compared with before treatment,the serum levels of Beclin-1,Atg7,and LC3-Ⅱ increased in the treatment group after treatment(P<0.01,P<0.05),while the serum level of Beclin-1 decreased in the control group after treatment(P<0.01).After treatment,the improvement of the above indicators in the treatment group were better than those in the control group(P<0.01,P<0.05).Correlation analysis showed that Beclin-1,Atg7,and LC3-Ⅱ were negatively correlated with Scr and BUN(P<0.05),and positively correlated with eGFR(P<0.05).There was no obvious adverse reaction in both groups.Conclusion The combination of Shen Shuai Ⅱ Granules and integrated Western medicine therapy for the treatment of primary CKD in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis has confirmed efficacy,which can effectively alleviate clinical symptoms,improve renal function,and delay the progression of CKD.The mechanism may be related to improving the level of autophagy in renal.

Discussion on the Prevention and Treatment of Urolithiasis by Integrated Traditional Chinese and Western Medicine based on “Shen-kidney Theory” / 中医杂志

The pathogenesis of urolithiasis is not yet clear， and there are obvious limitations in the prevention and treatment of urolithiasis by either Chinese or western medicine. The microscopic pathological changes of the kidney from anatomical perspective have a certain internal connection with viewpoint of “kidney storing insufficiency， and kidney deficiency as the root” in the traditional Chinese medicine （TCM） zang-fu （脏腑） theory. Accordingly， the prevention and treatment of urolithiasis by integrated traditional Chinese and western medicine based on “shen-kidney” theory has been proposed. It is believed that the prevention and treatment of urolithiasis can be divided into two stages， that is expelling stones and preventing stones. In terms of preventing stones from kideny， it is recommended to focus on the early pathological changes of the kidney； for preventing stones from shen， it is advised to prevent and treat urolithiasis from kidney deficiency. The treatment should be time-based and stage by stage. Adhering to the principle of “prevention before disease occurs， prevention is more important than treatment” aims to advance the intervention targets for the prevention and treatment of urolithiasis. Emphasizing on the simultaneous treatment of kidney disease and urolithiasis， it is critical to put focus on the development of calcium-containing crystalline nephropathy in the early stage of stone formation， as well as the fundamental pathogenesis of kidney deficiency in TCM. Shen-kidney theory aims to further promote the integration of traditional Chinese and western medicine in the prevention and treatment of urolithiasis， which may provide certain reference for solving the current dilemma of urolithiasis prevention and treatment.

SUN Shen-tian's clinical experience in treating Tourette's syndrome with acupuncture / 中国针灸

To introduce the clinical experience of professor SUN Shen-tian in treatment of Tourette's syndrome (TS) with acupuncture. TS is a psychosomatic disease and the core pathogenesis refers to blood deficiency producing internal wind. The disease is located in the heart and liver. Acupoints are selected according to the functional orientation of the cerebral cortex. The extrapyramidal system area is preferred for tic disorder, and the emotional area is for behavioral disorder. The treatment focuses on regulating the mind by multiple methods, including manual needling technique used the transcranial repeated acupuncture, and regulating the mind by taking multiple acupoints, Baihui (GV 20), Neiguan (PC 6), Shenmen (HT 7) and Dazhong (KI 4) are stimulated. For abdominal twitching and mental symptoms of TS children, the first and third abdominal areas are selected. The target symptoms (biao) are treated specially by local acupoints, the combination of the starting and ending acupoints of the affected meridian, or the acupoints of the meridians with same name. The modified chaihu longgu muli decoction and siwu decoction are prescribed to sooth liver, nourish blood and soothe wind. In association with the characteristics and target symptoms of TS, the sequential therapy is used with filiform needling, intradermal needling, Chinese herbal medication and psychotherapy.

Traditional Chinese medicine health care from "long term taking" drugs in Shen Nong's Classic of Materia Medica / 中国中药杂志

"Taking drugs for a long term" is a qualitative expression of medication method based on the efficacy and safety of Chinese medicine, and the study on it is conducive to the full utilization of the efficacy and rational use of drugs. There are 148 drugs that can be taken for a long time recorded in Shen Nong's Classic of Materia Medica, accounting for 41% of the total drugs. This paper analyzed three-grade classification, natural qualities, four properties and five flavors, and efficacy features of the "long-term taking" drugs(LTTD), thus exploring the herbal source of traditional Chinese medicine health care and the rationality of effect accumulation by long-term taking. It was found that there were more than 110 top-grade LTTD in Shen Nong's Classic of Materia Medica, most of which were herbs, with sweet flavor, flat property, and no toxicity. The efficacies were mainly making body feel light and agile(Qingshen) and prolonging life. Eighty-three LTTD were included in the Chinese Pharmacopoeia(2020 edition). In the modern classification, tonic LTTD accounted for the most, followed by damp-draining diuretic LTTD and exterior-releasing LTTD. Twenty LTTD were included in the "List of Medicinal and Edible Products" and 21 were in the "List of Products Used for Health-care Food", involving in various modern health care effects, such as enhancing immunity, assisting in reducing blood lipids, and anti-oxidation. Shen Nong's Classic of Materia Medica is the classic source of traditional Chinese medicine health care, and its medication thought of taking drugs for a long term to accumulate effects has guiding significance for the regulation of sub-health and chronic diseases nowadays. The efficacy and safety of LTTD have been examined in practice for a long time, and some of the drugs are edible, which is unique in the whole cycle of health-care service, especially in line with the health-care needs in the aging society under the concept of Big Health. However, some records in the book are limited by the understanding of the times, which should be scientifically studied according to the Chinese Pharmacopoeia and the related regulations and technical requirements, under the attitude of eliminating falsifications and preserving the truth and keeping the right essence, so as to achieve further improvement, innovation, and development.

Professor SUN Shen-tian's experience in acupuncture treatment of depression based on "psychosomatic medicine" / 中国针灸

This paper introduces professor SUN Shen-tian's clinical thoughts and his characteristics of acupuncture techniques for the treatment of depression based on "psychosomatic medicine". Professor SUN, the master of traditional Chinese medicine, believes that depression refers to comorbidity of "heart mind" and "body", resulting from the "body-mind" disharmony, specially dominated by the emotional disorder. This disease is located in the brain, with the injury of mind and closely related to the heart and liver dysfunction. In pathogenesis, the dysfunction of brain mind and the unhealthy conditions of body and mind are involved. The treatment should focus on "regulating the mind, improving the intelligence, co-modulating the abdominal and brain functions and treating the physical and mental disorders". Baihui (GV 20), Ningshen (Extra) and emotional area on the head are selected as the main points to benefit the intelligence and calming down the mind; the abdominal region 1 and region 8 of "Sun's abdominal acupuncture" are used as the main points of the abdomen to regulate the brain functions. The point prescription is modified according to the symptoms and etiologies. The repeated transcranial acupuncture stimulation and electroacupuncture at low frequency (2 Hz) are crucial to the therapeutic effect. Reliving anxious emotions is specially considered before acupuncture, and the mind is protected and deqi is consolidated during acupuncture.

Shen Qi Wan attenuates renal interstitial fibrosis through upregulating AQP1 / 中国天然药物

Renal interstitial fibrosis (RIF) is the crucial pathway in chronic kidney disease (CKD) leading to the end-stage renal failure. However, the underlying mechanism of Shen Qi Wan (SQW) on RIF is not fully understood. In the current study, we investigated the role of Aquaporin 1 (AQP1) in SQW on tubular epithelial-to-mesenchymal transition (EMT). A RIF mouse model induced by adenine and a TGF-β1-stimulated HK-2 cell model were etablished to explore the involvement of AQP 1 in the protective effect of SQW on EMT in vitro and in vivo. Subsequently, the molecular mechanism of SQW on EMT was explored in HK-2 cells with AQP1 knockdown. The results indicated that SQW alleviated kidney injury and renal collagen deposition in the kidneys of mice induced by adenine, increased the protein expression of E-cadherin and AQP1 expression, and decreased the expression of vimentin and α-smooth muscle actin (α-SMA). Similarly, treatmement with SQW-containing serum significantly halted EMT process in TGF-β1 stimulated HK-2 cells. The expression of snail and slug was significantly upregulated in HK-2 cells after knockdown of AQP1. AQP1 knockdown also increased the mRNA expression of vimentin and α-SMA, and decreased the expression of E-cadherin. The protein expression of vimentin increased, while the expression of E-cadherin and CK-18 significantly decreased after AQP1 knockdown in HK-2 cells. These results revealed that AQP1 knockdown promoted EMT. Furthermore, AQP1 knockdown abolished the protective effect of SQW-containing serum on EMT in HK-2 cells. In sum, SQW attentuates EMT process in RIF through upregulation of the expression of AQP1.

Mechanism of action of Shen-Fu decoction on cardiogenic shock based on network pharmacology and experimental validation / 中国药理学通报

Aim To investigate the mechanism of action of Shen-Fu decoction in the prevention and treatment of cardiogenic shock based on network pharmacology and animal experiments. Methods The relevant targets and signaling pathways of cardiogenic shock of Shen-Fu decoction were predicted by network pharmacology, and a cardiogenic shock rat model was created by coronary artery ligation. Before modeling, rats were given the appropriate dose of Shen-Fu decoction or saline by gavage for 14 days according to the group, and real-time mean arterial pressure (MAP) changes were recorded after successful modeling. HE method was used to detect the myocardial histopathological changes of cardiogenic shock. TUNEL method was employed to detect rat myocardial cell apoptosis, and Western blotting was applied to determine the expression levels of rat myocardial Bax, Bcl-2, caspase-3, cleaved caspase-3 proteins. Results A total of 51 potential active ingredients of Shen-Fu decoction were screened out by network pharmacology, 80 targets of co-action with cardiogenic shock, and 43 core targets of close relationship between proteins, and GO enrichment analysis revealed that the core proteins were involved in the biology process (BP), mainly involving positive regulation of apoptotic process. KEGG enrichment analysis showed signaling pathways involving atherosclerosis-related, apoptosis and other signaling pathways. The results of animal model validation showed that Shen-Fu decoction could increase the shock blood pressure of rats with cardiogenic shock and alleviate the pathological changes of myocardial tissue, reduce the degree of apoptosis of rat cardiomyocytes, reduce the expression level of caspase-3, cleaved caspase-3 and Bax protein in rat myocardial tissue, and improve the expression level of Bcl-2 protein in myocardial tissue of rats. Conclusions The potential active ingredient of Shen-Fu decoction may play a role in the prevention and control of cardiogenic shock rats by acting on the target Bax, Bcl-2 to regulate the apoptosis signaling pathway of cardiomyocytes.

OBJECTIVE@#To evaluate the effectiveness and safety of Zhenqi Buxue Oral Liquid (ZQ), progesterone capsules, and their combination in treating oligomenorrhea and hypomenorrhea with qi-blood and Kidney (Shen) essence deficiency.@*METHODS@#This was a prospective, randomized, multi-center controlled trial between June 2022 to December 2022. Ninety-six oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency were randomly assigned to receive ZQ (ZQ group, 29 cases), progesterone capsules (PG group, 32 cases), or the combined Chinese and Western medicine (COM group, 31 cases) at a ratio of 1:1:1. Patients in the ZQ or PG group took daily 10 mL twice a day of ZQ or 200 mg once a day of progesterone capsules for 10 consecutive days on day 15 of the menstrual cycle respectively, and patients in the COM group received the same ZQ combined with progesterone capsules. The treatment course lasted for 3 months and follow-up was performed at 1 and 3 months after the end of treatment. Primary endpoint was the menstrual Traditional Chinese Medicine Syndrome Scale (TCMSS) scores. Secondary endpoints included pictorial blood loss assessment chart (PBAC) scores, clinical efficacy rate, 36-item Short Form Health Survey (SF-36) scores, sex hormones and thickness of endometrium. Adverse events (AEs) were recorded.@*RESULTS@#TCMSS scores after 1- and 3-month treatment in all groups were significantly lower than those at baseline (P<0.05). Only TCMSS scores after 3-month treatment in the ZQ and COM groups continuously decreased compared with those after 1-month treatment in the same group (P<0.01). TCMSS scores after 3-month treatment in the ZQ and COM groups were significantly lower than those in the PG group (P<0.05, P<0.01). Compared with baseline, PBAC scores in the ZQ and COM groups after 3 months of treatment were also significantly higher (both P<0.01). The total effective rates of TCM syndrome of 3-month treatment were significantly improved in all groups compared with that after 1 month of treatment (P<0.05). The total effective rate of the COM group was the highest in the 3rd month of treatment and significantly higher than that of PG group alone (P<0.05). Compared with baseline, only the SF-36 scores of COM group were significantly improved after 3 months of treatment (P<0.05). No serious adverse reactions were observed after treatment.@*CONCLUSIONS@#The combination of ZQ and PG, or ZQ only had better effects on reducing TCMSS scores compared with PG, and COM showed the higher total effective rate compared with monotherapy. Besides, COM could effectively improve menstrual blood loss and quality of life. ZQ combined with PG may be an effective and safe option for oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency.

Objective To investigate the effect of Liu-Shen-Wan on transplanted tumors in mice with colon cancer based on the polarization of M2 macrophages in the tumor microenvironment. Methods We established a subcutaneous transplantation tumor model of mice with CT26 colon cancer. Mice were randomly divided into vehicle, oxaliplatin, and oxaliplatin combined with Liu-Shen-Wan groups. Treatment was administered for three weeks, and tumor volume was measured. All mice were weighed during the administration. After the end of the treatment, the mice were dissected and tumors were photographed and weighed. Spleen index was calculated. The expression levels of IFN-γ and IL-12P40 in serum and related blood biochemical indices were measured. The expression levels of M2 macrophage polarization indices, namely, IL-10 and TGF-β, in serum and tumor tissues were detected. The infiltration degree of M2 macrophages in each group was observed by immunohistochemical experiments. Results The tumor volume and mouse weight in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased compared with those in the vehicle group. The spleen index increased, and the expression levels of IFN-γ and IL-12P40 in serum also significantly increased. The mice had no obvious side effects after the drug treatment. In addition, the expression levels of IL-10 and TGF-β in the serum and tissues of mice in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased. The expression levels of CD68 and CD206 in tumor tissues also decreased. Conclusion The anti-tumor effect of Liu-Shen-Wan on the transplanted tumors of mice with colon cancer is related to the inhibition of M2 macrophage polarization in the tumor microenvironment.

Methods:Sixty SD rats were randomly divided into blank group, model group, positive control group, high dose Shen’an Decoction group, medium dose Shen’an Decoction group and low dose Shen’an Decoction group, with 10 rats in each group. Except the blank group, the other groups were intraperitoneally injected with cisplatin 7.5 mg/kg to prepare the acute kidney injured rat model. After the modeling, the high, medium and low dose groups of Shen’an Decoction were gavaged with 0.698, 1.395 and 2.790 g/ml Shen’an Decoction respectively, and the positive control group was gavaged with benazepril hydrochloride suspension of 5 mg/kg, once a day for 14 days. The kidney histopathological changes of rats in each group were observed by HE staining. The content of BUN, creatinine(CR), Cystatin C (Cys-C), TNF-α, and IL-6 in serum were detected by ELISA. The expression of TLR-4, NF-κB p65, myeloid differentiation factor (MyD88), and tumor necrosis factor receptor related factor 6 (TRAF-6) in renal tissue were detected by Western blot. Results:Compared with the model group, the growth condition of rats in each dose group of Shen’an Decoction was significantly improved ( P<0.05), and the kidney coefficient was significantly decreased ( P<0.05). The serum levels of BUN, Cr, Cys-C, TNF-α, IL-6 of rats in each dose group of Shen’an Decoction were significantly decreased ( P<0.05). The expression of TLR-4 (0.54 ± 0.07, 0.52 ± 0.09, 0.41 ± 0.04 vs. 0.86 ± 0.06), NF-κB (0.74 ± 0.02, 0.72 ± 0.06, 0.67 ± 0.05 vs. 0.93 ± 0.03), MyD88 (0.86 ± 0.02, 0.82 ± 0.03, 0.61 ± 0.02 vs. 1.04 ± 0.03), and TRAF-6 (0.65 ± 0.04, 0.58 ± 0.08, 0.54 ± 0.07 vs. 0.90 ± 0.06) in kidney tissue of rats in each dose group of Shen’an Decoction was significantly decreased ( P<0.05). Conclusion:Shen’an Decoction can protect the renal function of rats by inhibiting TLR4/NF-κB signaling pathway and alleviating the pathological changes of renal injury induced by cisplatin.

Effect of Bu Shen Yi Jing Fang on differentiation of peripheral blood stem cells and expression of ciliary neurotrophic factor in retina of dry ARMD mouse model / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the differentiation of bone marrow-derived mesenchymal stem cells from peripheral blood to the retina and the expression of ciliary neurotrophic factor(CNTF). We also investigate the mechanism by which Bu Shen Yi Jing Fang could treat dry age-related macular degeneration(ARMD). <p>METHODS:C57BL/6 mice were administered with sodium iodate(NaIO3)by tail intravenous injection. One day after modeling, 3×106 green fluorescent protein labeled bone marrow-derived mesenchymal stem cells(GFP-BMSCs)were injected into the tail vein. The injected mice were randomly divided into distilled water group and Bu Shen Yi Jing Fang group according to random number table, and 12 mice in each group. The mice were intragastrical administrated with either Bu Shen Yi Jing Fang solution or distilled water every day. Twelve healthy C57BL/6 mice were fed regularly as the normal group. At 14d after the treatment, the differentiation of GFP-BMSCs in retina was determined by immunofluorescence, and the expression of CNTF in the retina was detected by immunofluorescence and quantitative real-time PCR.<p>RESULTS: Immunofluorescence staining showed that there were more glial fibrillary acidic protein(GFAP)and GFP double-stained positive cells in the Bu Shen Yi Jing Fang group than in the distilled water group(<i>P</i><0.01), and the positive rate of retinal pigment epithelium 65(RPE65)was not significantly different between two groups(<i>P</i>>0.05). There were no Rhodopsin and GFP double-stained positive cells in the two groups. Immunofluorescence and quantitative real-time PCR showed that the expression of CNTF in the Bu Shen Yi Jing Fang group was higher than which in the distilled water group(<i>P</i><0.05). <p>CONCLUSION: Bu Shen Yi Jing Fang facilitated the differentiation of peripheral blood stem cells into glial cells in the retina and the expression of CNTF, which might be one of the mechanisms of Bu Shen Yi Jing Fang in the treatment of dry ARMD.

Effect of shenfu injection on isolated empty beating hearts from miniature pigs

Abstract Objective: To investigate the effect of Shenfu (SF) injection on donor heart preservation. Methods: Twelve pigs were randomly divided into SF group (n=6) and control group (n=6). After eight hours of perfusion, the differences in hemoglobin, the expression of Bcl-2 and BAX, and changes in the myocardial ultrastructure were compared to illustrate the effects of SF injection in heart preservation. Results: The differences in free hemoglobin between the SF group and the control group were statistically significant (P=0.001), and there was significant interaction of groups with times (P=0.019), but the perfusion time may not be associated with the hemoglobin concentration (P=0.616). According to Western blotting analysis, the expression of Bcl-2 was higher in the SF group than in the control group, while the expression of BAX was not different between the two groups. As to ultrastructural changes, both groups exhibited mitochondrial swelling and myofilament lysis, but the degree of damage in the SF group was smaller. Conclusion: Our study suggests that the application of SF injection for heart preservation may protect against cardiomyocytes and erythrocytes apoptosis, and Bcl-2 protein may play a role in these physiological processes.

Comparative study on icariin and Bu-Shen-Gu-Chi-Wan for alveolar reconstruction in chronic periodontitis in rats / 口腔疾病防治

Objective@#To observe the effects of icariin (ICA) and Bu-Shen-Gu-Chi-Wan on the alveolar bone absorption of chronic periodontitis in rats, and to explore the effect and possible mechanism of ICA in the treatment of chronic periodontitis. @*Methods@#After the establishment of the periodontitis model, the rats were divided into the periodontitis group (group P), ICA high dose group (group H), ICA low dose group (group L) and Bu-Shen-Gu-Chi-Wan treatment group (group B). Each group received treatment for one month and two months, separately, and the serum osteocalcin (OCN) level was measured. Three-dimensional reconstruction was performed after micro computed tomography (micro CT) scanning to measure the bone parameters of specific points, and the distance between the enamel cementum boundary and alveolar crest (CEJ-ABC) was recorded as alveolar bone resorption value. Tissue sections were generated to evaluate the effect of ICA on alveolar bone repair and reconstruction in rats with experimental periodontitis. @*Results@# Compared with the periodontitis group (group P), OCN levels in the serum in treatment groups (groups H, L and B) were decreased significantly (P < 0.05); the values of bone volume/tissue volume (BV/TV) and trabecular number (Tb.N) in treatment groups (groups H, L and B) were significantly higher than that in group P (P < 0.05). Compared with group P, trabecular thickness (Tb.Th) values of groups H and B significantly increased, and trabecular separation (Tb.Sp) of groups H and B significantly decreased (P < 0.05). The changing trend of parameters in group L was the same as that in group H but only after two months of administration. The difference between Tb.Sp values in groups L and P was statistically significant (P < 0.05). Compared with group P, the CEJ-ABC distance significantly reduced in group L (1 month and 2 months after administration), group H (1 month and 2 months after administration), and group B (only 2 months after administration) (P < 0.05).@*Conclusion@#ICA and Bu-Shen-Gu-Chi-Wan improve the alveolar bone resorption in an experimental model of chronic periodontitis in rats, and the mechanism may be related to the regulation of osteocalcin serum levels.
