Experience in Treatment of COVID-19 by Elimination of Pathogens Through Purgation and Diuresis / 中国实验方剂学杂志

Coronavirus disease-2019 (COVID-19) outbreaks were spreading rapidly around the world in early 2020. This disease is within the category of "damp epidemic" and "damp toxin epidemic" in traditional Chinese medicine, with lung and spleen as the lesion focuses, while dampness and toxin as especially prominent properties. Through clinical observation, we found that dampness would often transform into damp heat during the development and evolution of the disease, and the "triple energizer" treatment was an important therapeutic method, eliminating pathogens through purgation and diuresis: for those with damp-heat accumulation toxin diffused to the triple energizer, we could use Ganlu Xiaodudan as primary prescription, which can spread the upper part, smooth the middle part and infiltrate the lower part, so as to provide a way out for the pathogenic factors and regulate Qi movement. For those with damp-heat in Shaoyang channel, we could use Haoqin Qingdantang to clear heat and promote diuresis, harmonize Shaoyang, eliminate damp-heat and epidemic pathogenic factor. For those with pathogen hidden in membrane source dampness trapping and hidden heat, we could use Dayuanyin to eliminate pathogens between interior and exterior parts, and regulate Qi movement. At the same time we shared three typical cases treated in Wuhan, and conducted an in-depth analysis in this study. Clinically, the method of elimination of pathogens through purgation and diuresis is mainly used in the early and middle stage of this disease. When the disease is still located in Qi system, it also can be applied to mild, ordinary patients and severe patients that have accurate syndrome differentiation. In such cases, it can effectively improve symptoms, reduce pathogenic toxin, truncate and reverse the course of disease, give way to pathogen, and avoid disease aggravating.

Dietary supplementation with soybean oligosaccharides increases short-chain fatty acids but decreases protein-derived catabolites in the intestinal luminal content of weaned Huanjiang mini-piglets.

The improvement of gut health and function with prebiotic supplements after weaning is an active area of research in pig nutrition. The present study was conducted to test the working hypothesis that medium-term dietary supplementation with soybean oligosaccharides (SBOS) can affect the gut ecosystem in terms of microbiota composition, luminal bacterial short-chain fatty acid and ammonia concentrations, and intestinal expression of genes related to intestinal immunity and barrier function. Ten Huanjiang mini-piglets, weaned at 21 days of age, were randomly assigned to 2 groups. Each group received a standard diet containing either dietary supplementation with 0.5% corn starch (control group) or 0.5% SBOS (experimental group). The results showed that dietary supplementation with SBOS increased the diversity of intestinal microflora and elevated (P < .05) the numbers of some presumably beneficial intestinal bacteria (e.g., Bifidobacterium sp, Faecalibacterium prausnitzii, Fusobacterium prausnitzii, and Roseburia). Soybean oligosaccharide supplementation also increased the concentration of short-chain fatty acid in the intestinal lumen, and it reduced (P < .05) the numbers of bacteria with pathogenic potential (e.g., Escherichia coli, Clostridium, and Streptococcus) and the concentration of several protein-derived catabolites (e.g., isobutyrate, isovalerate, and ammonia). In addition, SBOS supplementation increased (P < .05) expression of zonula occludens 1 messenger RNA, and it decreased (P < .05) expression of tumor necrosis factor α, interleukin 1ß, and interleukin 8 messenger RNA in the ileum and colon. These findings suggest that SBOS supplementation modifies the intestinal ecosystem in weaned Huanjiang mini-piglets and has potentially beneficial effects on the gut.

Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure.

AIM: To study the clinical efficacy of traditional Chinese medicine (TCM) intervention "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") for treating liver failure due to chronic hepatitis B. METHODS: We designed the study as a randomized controlled clinical trial. Registration number of Chinese Clinical Trial Registry is ChiCTR-TRC-12002961. A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study. Participants were randomly assigned to the following three groups: (1) a modern medicine control group (MMC group, 36 patients); (2) a "tonifying qi and detoxification" ("TQD") group (72 patients); and (3) a "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") group (36 patients). Patients in the MMC group received general internal medicine treatment; patients in the "TQD" group were given a TCM formula "tonifying qi and detoxification" and general internal medicine treatment; patients in the "TTK" group were given a TCM formula of "TTK" and general internal medicine treatment. All participants were treated for 8 wk and then followed at 48 wk following their final treatment. The primary efficacy end point was the patient fatality rate in each group. Measurements of various virological and biochemical indicators served as secondary endpoints. The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups. RESULTS: At the 48-wk post-treatment time point, the patient fatality rates in the MMC, "TQD", and "TTK" groups were 51.61%, 35.38%, and 16.67%, respectively, and the differences between groups were statistically significant (P < 0.05). However, there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups (P > 0.05). Patients in the "TTK" group had significantly higher levels of serum total bilirubin compared to MMC subjects (339.40 µmol/L ± 270.09 µmol/L vs 176.13 µmol/L ± 185.70 µmol/L, P = 0.014). Serum albumin levels were significantly increased in both the "TQD" group and "TTK" group as compared with the MMC group (31.30 g/L ± 4.77 g/L, 30.72 g/L ± 2.89 g/L vs 28.57 g/L ± 4.56 g/L, P < 0.05). There were no significant differences in levels of alanine transaminase among the three groups (P > 0.05). Safety data showed that there was one case of stomachache in the "TQD" group and one case of gastrointestinal side effect in the "TTK" group. CONCLUSION: Treatment with "TTK" improved the survival rates of patients with liver failure due to chronic hepatitis B. Additionally, liver tissue was regenerated and liver function was restored.

The prevention and treatment of heijingpaichitang for immune rejection following high-risk corneal transplantation in rats / 中华实验眼科杂志

The rate of corneal graft rejection is still high for high-risk keratoplasty although immune suppression drug is routinely used.The role of traditional Chinese medicine in corneal transplantation is concerned gradually.Heijingpaichitang on the prevention and treatment of rats with high-risk corneal allograft rejection needs further study.Objective This study was to investigate the inhibitory effect of heijingpaichitang on high-risk corneal transplantation immune rejection in rats.Methods Sixteen female SD rats were used as the donors and 32female Wistar rats were served as recipients.The high-risk corneal trasplantation models were established by corneal suture in 32 Wistar rats,and then homogeneity variant SD-Wistar corneal transplantation was performed.The recipients were randomized into model control group,cyclosporinc A (CsA)group,heijingpaichitang group and CsA +heijingpaichitang group.CsA,heijingpaichitang and CsA + heijingpaichitang was orally administered 4 days after operation once per day for 15 days,and normal saline solution was used at the same way in the model control group.Ocular anterior segment reaction was examined under the slit lamp and corneal opacification,edema and neovasculation were scored based on Larkin' s criteria.Rejection index of the corneal graft was recorded and the graft survival time was calculated.The pathological examination of the corneal graft was carried out in all rats,and the inflammatory cells in the corneas and CD4+ cells in the periphery blood were assayed using flow cytometry.The use of the animals complied with ARVO Statement.Results Corneal graft rejection occurred in 10 days after operation in the model control group,12-13 days in the CsA group and heijingpaichitang group and 22 days in the CsA +heijingpaichitang group.Compared with model control group,the scores of the corneal opacification,corneal edema and neovascularization were significantly lower in the CsA group,heijingpaichitang group and CsA+heijingpaichitang group (P＜0.05),and all the scores were declined in the CsA+ heijingpaichitang group compared with CsA group and heijingpaichitang group(P＜0.01),but no significant differences were seen in the scores between the CsA group and heijingpaichitang group(P＞0.05).The mean survival time of grafts was (10.38 ±1.69)days in the model control group,(22.50 ± 3.07) days in the CsA + heijingpaichitang group,with the significant difference (t =-9.790,P =0.000).The pathological examination of graft showed that the lymphocytes and new blood vessels were less in the CsA+heijingpaichitang group compared with CsA group and heijingpaichitang group 15 days after operation.Flow cytometry verified that the number of lymphocytes in graft,CD4+cells and CD4+/CD8+ in periphery blood were significantly lower in the heijingpaichitang group,CsA group and CsA+heijingpaichitang group compared with model control group (P＜0.05).Conclusions Heijingpaichitang can inhibit immune rejection to certain extent in high-risk corneal transplantation rat and has a similar effect to 0.1％ CsA.Heijingpaichitang and 0.1％ CsA have a synergistic effect.

ObjectiveTo investigate the effects of acupuncture on the serum leptin and IGF-1 in patients with post-stroke depression (PSD).MethodsBy using Hamilton rating scale for depression (HAMD),94 patients with PSD were recruited and randomly divided into 2 groups:acupuncture group and control group.All patients were given routine clinical treatments and second level medical prevention.Patients in the acupuncture group received Linggui Ba fa acupuncture treatment and oral administration of Sertraline and patients in the control group were treated with oral administration of Sertraline only.Serum levels of letpin and insulin growth factor (IGF-1) were measured by enzyme linked immunosorbent assay (ELISA) before and after treatments in all patients.ResultsThe levels of leptin and IGF-1 in patients of acupuncture group were significantly lower than that of the control group after treatment[(17.06 ± 12.38) ng/ml vs (32.27 ± 15.09)ng/ml,P＜0.01; (52.61±24.74)ng/ml vs (77.15±20.83)ng/ml,P＜0.01 respectively].The scores of HAMD in acupuncture group were significantly lower than that of control group after the treatment[(8.06±3.32)、(13.67±8.05)]and 6 month later[(6.52±2.08)、(10.26±6.16)].ConclusionThe serum levels ofleptin and IGF-1 were significantly lower and depression symptoms were improved after acupuncture in elderly patients with post-strok depressin.

Interventional value of total flavonoids from Rhizoma Drynariae on Cathepsin K, a potential target of osteoporosis.

Osteoporosis, the sixth most common disease in the world, is bringing increasingly serious harm to people's health. Cathepsin K, which plays an important role in bone resorption, is a potential target in the treatment of osteoporosis. Total flavonoids, the active ingredients in Rhizoma Drynariae, have shown obvious, therapeutic effect on osteoporosis. In previous studies, it was presumed that the mechanism for the therapeutic effect was through inhibiting the expression of Cathepsin K. However, there are still no detailed reports on some key issues such as the specific inhibitory results of total flavonoids on Cathepsin K and the pathway of inhibition and so on. Based on previous studies on total flavonoids from Rhizoma Drynariae, the pathway for the effect of, total flavonoids inhibiting Cathepsin K and their interventional value on Cathepsin K were analyzed in this paper, so as to explore the interventional feasibility and value of total flavonoids in Rhizoma Drynariae on Cathepsin K.

[Effect of qianggu drink ([Chinese characters: see text]) on bone histomorphometry of lumbar vertebrae in ovariectomized rats].

OBJECTIVE: To observe the effect of Chinese herbal medicine Qianggu drink ([Chinese characters: see text]) on bone histomorphometry of lumbar vertebrae in ovariectomized rats and to explore its mechanism. METHODS: Sixty female SD rats (weight 230 to 280 gram) were randomized into three groups: Qianggu drink ([Chinese characters: see text]) group (treatment group), Miacalcic group (control group) and blank group. The osteoporosis model was established successfully after all rats were ovariectomized for 10 weeks. The treatment group was used intragastric infusion with Qianggu drink ([Chinese characters: see text]) 0.001 ml/kg once a day. The control group was used hypodermic injection once a day with Miacalcic 0.72 U/kg. Five rats were killed respectively and the lumbar specimens were taken and cut for bone histomorphometric analysis at 45, 90, 135 and 180 days after the treatment. RESULTS: The thickness of trabecular bone in treatment group had the statistical significance with control group at 135 days after ovariectomized rats were given the medicine. The data of BV/TV and the thickness and space of trabecular bone had statistical significance compared with control group and blank group 180 days later. CONCLUSION: Qianggu drink ([Chinese characters: see text]) could effectively improve the histomorphometry indexes. The mechanism probably plays by stimulating osteogenesis and inhibiting the cytoactive of osteoclast and the trend of bone transform.

SP, DP, HR, SpO2, the degree of motor and sensory blockade and the side effect were observed.@*RESULTS@#SP/DP was significantly decreased in Group C than that in Group and Group B (p<0.05), HR and SpO2 in group B were decreased to different degrees 15 min after the injection (p<0.05). The complete recovery time of motor nerve blockade and the regression time of sensory blockade were obviously prolonged in Group C (p<0.05). There were no significant differences in analgesic effect among the three groups during the operation, but the incidence of pruritus was higher in both group A and Group B than that in Group C during the first 24 hours after the injection.@*CONCLUSION@#Spinal anesthesia with low dose sufentanil-bupivacaine possesses relatively steady hemodynamics. The blockade degree of motor and sensory blockade in this spinal anesthesia is lower than that in standard spinal bupivacaine in TURP.

Influence of ganciclovir and astragalus membranaceus on proliferation of hematopoietic progenitor cells of cord blood after cytomegalovirus infection in vitro / 中华儿科杂志

<p><b>OBJECTIVE</b>Cytomegalovirus (CMV) infection was greatly common in the world. CMV infection produces usually mild or asymptomatic infections in individuals with normal immune responses, whereas it may cause serious disease in immunosuppressive patients. Clinical manifestations include suppression of myelopoiesis, a mononucleosis like syndrome, hepatosplenomegaly, lymphadenopathy, thrombocytopenia, and hemolytic anemia. In patients undergoing bone marrow transplantation CMV remains the most common infectious causes of morbidity and mortality. But the treatment drugs with specific effect for CMV was fewer at the present. This study was to investigate the effect of CMV on proliferation of colony forming unit granulocyte-macrophage (CFU-GM), CFU-erythroid (CFU-E), brust forming unit-erythroid (BFU-E), CFU-multipotential (CFU-Mix) and CFU-megakaryocyte (CFU-Mk) progenitor cells of cord blood (CB) with the presence of ganciclovir (GCV) and astragalus membranaceus in vitro.</p><p><b>METHODS</b>Twenty CB samples were collected from fetal umbilical vein of normal term spontaneous delivery neonates. The colony forming unit-assay was applied to observe the suppression effect of CMV-AD169 strain on CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk of CB with the presence of GCV and astragalus membranaceus in vitro. The technique of PCR was used to demonstrate the existence of CMV-AD169 DNA in the colony cells of cultured CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk.</p><p><b>RESULTS</b>(1) The numbers of CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk colonies in CMV infection groups were significantly less than those in blank and mock group, respectively. The last time of colonies in groups with CMV infection was significantly shorten compared with the blank and mock group. (2) CMV-DNA was positively detected in the colony cells of CMV infection groups by PCR, while negative in the control groups. (3) The lasting time of CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk colonies infected with CMV extended significantly with the presence of astragalus membranaceus and GCV, and the numbers of those increased significantly compared with the CMV infection group, respectively. The increasing rate of colonies was 27.2%, 45.2%, 49.1%, 39.0% and 11.9% with astragalus membranaceus group, 37.4%, 74.2%, 71.7%, 67.4% and 38.9% with GCV group, 53.6%, 83.8%, 88.7%, 87.8% and 61.5% with astragalus membranaceus and GCV group, respectively.</p><p><b>CONCLUSIONS</b>The differentiation and proliferation of CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk were significantly inhibited after infected with CMV-AD169 strain. The suppression effect of CMV-AD169 on CFU-GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk was inhibited with the presence of GCV and astragalus membranaceus in vitro. This suggested that CMV-AD169 may be inhibited or killed by GCV and Astragalus Membranaceus in vitro.</p>

Effects of hyperbaric oxygenation on rabbits 'testes with varicocele / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the mechanism of male infertility caused by varicocele by evaluating the effects of hyperbaric oxygenation (HBO) therapy on the testicular tissue morphology and function of rabbit model with varicocele(VC).</p><p><b>METHODS</b>Twenty-four mature male rabbits were randomly divided into three groups: pseudo-operation, VC model and VC model administered by HBO. Experimental varicocele was induced by partial ligation of the left "lumbotesticular" trunk vein in rabbits. HBO was administered to one of the two groups of VC model rabbits after the operation. Weight and volume of both testes, parameters of seminal fluid, histological changes of testicular tissues, MTDs, TFI, and Sertoli cell index (SI) of seminiferous tubules were studied.</p><p><b>RESULTS</b>The average weight and volume of the left testes significantly increased in the rabbits treated by HBO. The semen quality was improved, and MTDs increased significantly compared with VC group(P < 0.0001). The testicular tissue morphology became nearly normal in VC + HBO group.</p><p><b>CONCLUSIONS</b>1. Both the structure and spermatogenetic function of testes can be damaged by the presence of varicocele; 2. Chronic ischemia, anoxia and microcircular dysfunction may be the key process and essential factor that make varicocele contributive to testicular damage and spermatogenetic dysfunction; 3. HBO can effectively alleviate, even eliminate, chronic ischemia, anoxia and microcircular dysfunction in testicular tissues with varicocele, and thus protect the structure and functions of testes.</p>
