The most cited references mainly focused on inflammation. Gastrointestinal and cardiovascular disorders were the most active medical conditions studied in this field. CONCLUSIONS: Research related to acupuncture regulation on the ANS mainly focused on anti-inflammation, and regulating gastrointestinal and cardiovascular function over the past decade. However, the mechanisms of the autonomic effects of acupuncture need further investigation. High-quality clinical studies are required to determine the optimal parameters of acupuncture for clinical application.

Physalis pubescens L. branch and leaf extracts inhibit lymphoma proliferation by inducing apoptosis and cell cycle arrest.

Physalis pubescens L. is an annual or perennial plant in the family Solanaceae It is used in traditional medicine for treating sore throats, coughs, urinary discomfort, and astringent pain, and externally for pemphigus and eczema in northern China. The proliferation inhibitory activity and mechanisms of the ethyl acetate extract (PHY-EA) from the leaves of Physalis pubescens were investigated. High performance liquid chromatography was used to identify the chemical composition of PHY-EA; sulforhodamine B was used to detect the proliferation inhibitory effect of PHY-EA on MCF-7, CA-46, Hela, HepG2, B16, and other tumor cells; flow cytometry was used to detect the effect of PHY-EA on the lymphoma cell cycle and apoptosis; Western blot was used to detect the expression of the cycle- and apoptosis-related proteins. The expression of Ki-67 and cleaved caspase 3 was detected by immunohistochemistry. The results showed that PHY-EA contained physalin B, physalin O, and physalin L. PHY-EA blocked the cell cycle of G2/M→G0/G1 in lymphoma cells and induced apoptosis in tumor cells. Mouse transplantation tumor experiments showed that PHY-EA had a significant inhibitory effect on mouse transplantation tumors, and the tumor volume and weight were significantly reduced. In conclusion, PHY-EA has a good antiproliferative effect on Burkkit lymphoma, indicating its potential medicinal value.

Treatment and prognosis of primary ocular adnexal extranodal marginal zone mucosa-associated lymphoid tissue lymphoma: a report from a single center / 中华血液学杂志

Objective: This study aimed to see how different initial treatment regimens affected the long-term prognosis of patients with extranodal marginal zone mucosa-associated lymphoid tissue lymphoma confining to the ocular adnexal (OAML) . Methods: Between April 2008 and April 2019, 109 patients with initial mucosa-associated lymphoid tissue confining to ocular adnexal were evaluated and followed-up, and the prognosis of various initial treatment regimens were examined. Results: A total of 36 patients underwent complete surgical resection of the lesions, and 73 patients had residual lesions after surgery, of which 37 patients chose watchful waiting, and 36 patients chose treatment. The treatment regimen included local radiotherapy and systemic treatment (chemotherapy, immunochemotherapy, the combination of radiotherapy and chemotherapy, etc.) , and no serious toxic and side effects were observed in patients receiving systemic treatment. The median follow-up time was 61 (10-142) months. The 5-year and 10-year progression-free survival (PFS) of monocular involvement patients were 78.2% and 76.0% . The 5-year and 10-year PFS rates of patients with binocular involvement were 64.4% and 23.5%. There was significant diference in PFS between patients with monocular and binocular involvement (P=0.010) . Patients who received additional treatment had higher PFS than those patients in the watchful waiting group (P=0.046) . The 5-year PFS was 71.4% and 90.1% among patients in the watchful waiting group and those who received additional treatment, whereas the 10-year PFS was 63.5% and 75.1% , respectively. Patients with OAML were still a risk of disease progression after 5 years. Conclusions: Patients with binocular involvement OAML at the start of the disease had a poor prognosis, but treatment could reduce the risk of recurrence/progression. Systemic therapy is one of the first-line treatment options for patients with OAML, who require long-term monitoring.

Extracts of Poria cocos polysaccharides improves alcoholic liver disease in mice via CYP2E1 and NF-κB inflammatory pathways / 中国中药杂志

The present study investigated the effect of extract of Poria cocos polysaccharides(PCP) on cytochrome P450 2 E1(CYP2 E1) and nuclear factor κB(NF-κB) inflammatory signaling pathways in alcoholic liver disease(ALD) mice and explored its protective effect and mechanism. Sixty male C57 BL/6 N mice of SPF grade were randomly divided into a control group, a model group, a positive drug group(bifendate, 200 mg·kg~(-1)), and high-(200 mg·kg~(-1)) and low-dose(50 mg·kg~(-1)) PCP groups. Gao-binge mo-del was induced and the mice in each group were treated correspondingly. Liver morphological and pathological changes were observed and organ index was calculated. Serum levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were detected. Malondialdehyde(MDA) and superoxide dismutase(SOD) in liver tissues were detected by assay kits. The levels of interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) were detected by ELISA. The activation of macrophages was observed by immunofluorescence staining and protein expression of CYP2 E1, Toll-like receptor 4(TLR4), NF-κB p65, and phosphorylated NF-κB p65(p-NF-κB p65) were analyzed by Western blot. The ALD model was properly induced. Compared with the model group, the PCP groups significantly improved the pathological injury of liver tissues. Immunofluorescence staining revealed that compared with the model group, the groups with drug intervention showed decreased macrophages in liver tissues. Additionally, the PCP groups showed reduced ALT, AST, MDA, IL-6, and TNF-α(P<0.05), and potentiated activity of SOD(P<0.01). PCP extract has the protective effect against alcoholic liver injury in mice, and the underlying mechanism may be related to the regulation of the expression of CYP2 E1 and inhibition of TLR4/NF-κB inflammatory signaling pathway to reduce oxidative stress and inflammatory injury, thereby inhibiting the development of ALD.

Establishment of Feedforward Control Model for Dry Granulation of Polysaccharide Components Based on Quality by Design / 中国实验方剂学杂志

ObjectiveA feedforward control model for dry granulation of polysaccharide components was established to guide the adjustment and optimization of critical process parameters （CPPs） in the design space， so as to reduce the impact of fluctuations in raw materials properties on the quality of medicines. MethodTaking Astragali Radix extract powder as the model drug， the design space of dry granulation CPPs was determined by Box-Behnken design. Astragali Radix mixed powder with different powder properties were prepared by mixture design， the variance inflation factor （VIF） was used to diagnose the multicollinearity of the powder properties， and principal component analysis （PCA） was used to extract the characteristic data of the model. Radial basis function neural network （RBFNN） was used to establish a feedforward control model for reflecting the relationship between the powder properties of polysaccharide components， dry granulation CPPs and one-time molding rate. ResultThe design space for dry granulation CPPs of polysaccharide components was 16-35 Hz for feeding speed， 10-23 Hz for roller speed， and 10-46 kg·cm-2 for roller pressure. The established RBFNN feedforward control model had a good predictive effect on the one-time molding rate of dry granulation of polysaccharide components， which could be used to guide the adjustment and optimization of CPPs in the design space， the relative error was 0.38%-6.73%， and the average relative error was 3.42%. ConclusionThe established feedforward control model can well reflect the relationship between the powder properties of the polysaccharide components， the dry granulation CPPs and the one-time molding rate of the granules， which can be used to guide the adjustment and optimization of CPPs in the design space， reduce the impact of material property fluctuation on product quality， and provide ideas for promoting the quality of traditional Chinese medicine from passive control to active control.

Efficacy and Safety of Traditional Chinese Herbal Medicine for Antipsychotic-Related Constipation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Constipation is a common but often ignored side effect of antipsychotic treatment, although it is associated with adverse outcomes. The results of the efficacy and safety of traditional Chinese herbal medicine (TCM) in treating constipation are mixed across studies. This is a systematic review and meta-analysis of randomized controlled trials (RCTs) of the efficacy and safety of TCM compared to Western medicine (WM) in treating antipsychotic-related constipation. Methods: Major international electronic (PubMed, EMBASE, Cochrane Library, and Web of Science) and Chinese (Wanfang, WeiPu VIP, SinoMed, and CNKI) databases were searched from their inception to November 29, 2020. Meta-analysis was performed using the random-effects model. Results: Thirty RCTs with 52 arms covering 2,570 patients in the TCM group and 2,511 patients in the WM group were included. Compared with WM, TCM alone was superior regarding the moderate response rate [risk ratio (RR) = 1.165; 95% confidence interval (CI): 1.096-1.238; P < 0.001], marked response rate (RR = 1.437; 95% CI: 1.267-1.692; P < 0.001), and remission rate (RR = 1.376; 95% CI: 1.180-1.606; P < 0.001) for constipation, while it was significantly associated with lower risk of rash (RR = 0.081; 95% CI: 0.019-0.342; P = 0.001). For the moderate response rate, meta-regression analyses revealed that publication year (ß = -0.007, P = 0.0007) and Jadad score (ß = 0.067, P < 0.001) significantly moderated the results. For the remission rate, subgroup and meta-regression analyses revealed that the geographical region (P = 0.003), inpatient status (P = 0.035), and trial duration (ß = 0.009, P = 0.013) significantly moderated the results. Conclusions: The efficacy of TCM for antipsychotic-related constipation appeared to be greater compared to WM, while certain side effects of TCM, such as rash, were less frequent.

Material manufacturability classification in high shear wet granulation process of Chinese medicine / 中国中药杂志

The high shear wet granulation(HSWG) process of Chinese medicine has a complicated mechanism. There are many influencing factors that contribute to this process. In order to summarize the manufacturability of different kinds of materials in HSWG, this paper constructed a material library composed of 11 materials, including 4 Chinese medicine extracts and 7 pharmaceutical excipients. Each material was described by 22 physical parameters. Several binders were employed, and their density, viscosity and surface tension were characterized. Combining empirical constraints and the principle of randomization, 21 designed experiments and 8 verification experiments were arranged. The partial least squares(PLS) algorithm was used to establish a process model in prediction of the median granule size based on properties of raw materials and binders, and process parameters. The surface tension and density of binders, as well as the maximum pore saturation were identified as key variables. In the latent variable space of the HSWG process model, all materials could be divided into three categories, namely the Chinese medicine extracts, the diluents and the disintegrants. The granulation of Chinese medicine extracts required low viscosity and low amount of binder, and the resulted granule sizes were small. The diluent powders occupied a large physical space, and could be made into granules with different granule sizes by adjusting the properties of binders. The disintegrants tended to be made into large granules under the condition of aqueous binder. The combination use of material database and multivariate modeling method is conducive to innovate the knowledge discovery of the wet granulation process of Chinese medicine, and provides a basis for the formulation and process design based on material attributes.

Effects of Shuanghuanglian oral liquids on patients with COVID-19: a randomized, open-label, parallel-controlled, multicenter clinical trial / 医学前沿

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

Anti-tumor Effect and Mechanism of Kaempferol： A Review / 中国实验方剂学杂志

Cancer is a threat to human health. New treatments for cancer can significantly prolong the survival time of patients， but fail to improve the adverse reactions induced by chemoradiotherapy. Improving patient outcomes still requires the effort of cancer researchers. In recent years， the anti-tumor effects of active components from Chinese herbs have received wide attention. Kaempferol， a flavonoid mainly found in the medicinal plant Kaempferia galanga， can be used to treat obesity， cardiovascular diseases， diabetes and other diseases. It has also exhibited good efficacy in inhibiting the occurrence and development of liver cancer， colon cancer， lung cancer， ovarian cancer， and other malignant tumors. Kaempferol mainly exerts the anti-cancer effect by inducing apoptosis. Specifically， it promotes the production of intracellular reactive oxygen species （ROS） and triggers cell apoptosis through the mitochondrial pathway. Besides， it is capable of interfering with the cancer cell cycle， causing most cancer cells to arrest in the G2/M phase， and inducing cell autophagy， a programmed cell death， thus inhibiting cell migration and invasion and angiogenesis， synergistically improving chemotherapeutic drug efficacy， and reducing adverse effects. Kaempferol acts on a series of intracellular and extracellular targets to participate in the regulation of tumor cell signaling pathways， involving phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， epidermal growth factor receptor （EGFR）， mitogen activated protein kinase （MAPK）， and Wnt signaling pathways， with the PI3K/Akt signaling pathway being most significant. In addition， kaempferol also plays an important regulatory role in tumor epigenetics. This paper reviewed the anti-tumor effect and mechanism of kaempferol， aiming to provide reference for in-depth study on its prevention and treatment of tumor and the development of new anti-tumor drugs.

Mechanism of Chinese Medicine Against Angiogenesis in Lung Cancer： A Review / 中国实验方剂学杂志

Lung cancer is a malignant tumor with high incidence and high mortality， posing a great threat to human health. Neovascularization may be one of the important mechanisms of lung cancer. The growing lung cancer cells can obtain necessary nutrients from the newly formed blood vessels， thereby causing the spread and metastasis of lung cancer. Nowadays， anti-angiogenic drugs are commonly used in western medicine in addition to surgery，radiotherapy， chemotherapy， and immunotherapy. However， the resulting adverse reactions such as thrombosis， hypertension， diarrhea， and cardiotoxicity have seriously affected the quality of life of patients. As the recognition of angiogenesis deepens， the selection of lung cancer treatment options has become a research hotspot and difficulty in the field of lung cancer treatment. In traditional Chinese medicine（TCM）， angiogenesis is believed to fall into the category of “collateral disease”. The invasion of external pathogens and deficiency of healthy Qi will cause visceral dysfunction， which can be gradually followed by Qi obstruction and blood stasis and phlegm-turbidity congesting the collaterals. As a result， the collateral function will be damaged， providing favorable conditions for the occurrence of lung cancer. More and more modern studies have confirmed that TCM is able to inhibit angiogenesis in the lung cancer， thereby resisting the tumor. In addition， by virtue of the unique advantages， TCM effectively reduces adverse reactions， enhances the efficacy， and improves the living conditions of patients. Moreover， it can synergize with other western medicine therapies in the treatment of lung cancer， exhibiting a wide application prospect. This paper summarizes the mechanisms of TCM in inhibiting angiogenesis of lung cancer reported in relevant experimental research， hoping to provide reference for the optimization of clinical treatment strategies for lung cancer.

Prediction of Disintegration Time of Traditional Chinese Medicine Tablets Based on Generalized Regression Neural Network / 中国实验方剂学杂志

Objective:This paper constructs a generalized regression neural network （GRNN） model to predict the disintegration time of traditional Chinese medicine （TCM） tablets. Method:Taking Astragali Radix as a model drug， the mixed Astragali Radix powders with different powder properties were prepared by mixing Astragali Radix extract powders with microcrystalline cellulose and lactose， which were made to Astragali Radix tablets by direct compression method. The powder properties of mixed Astragali Radix powders and the disintegration time of Astragali Radix tablets were determined， respectively. The correlation between the original data was eliminated by principal component analysis （PCA）. The principal component factors were used as the input layer of the GRNN model， and the disintegration time was used as the output layer for network training. Finally， the verification group data was used to predict the disintegration time， and the network prediction accuracy was calculated by comparing with the actual value. Result:Three principal component factors were obtained through PCA by analyzing the original nine variables that were correlated with each other （Hausner ratio， true density， tap density， compression degree， angle of repose， bulk density， porosity， water content and total dissolved solids）， which reduced the complexity of the network. The prediction value of the disintegration time based on this prediction method was in good agreement with the actual value， the error of disintegration time was 0.01-1.34 min and the average relative error was 3.16%. Conclusion:Based on the GRNN mathematical model， the physical properties of Astragali Radix extract powders can be used to accurately predict the disintegration time of Astragali Radix tablets， which provides a reference for studying the disintegration time of TCM tablets.

Systematic evaluation of Huaier Granules adjuvant treatment of primary liver cancer / 中国中药杂志

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.

Network Meta-analysis of oral Chinese patent medicine for adjuvant treatment of primary liver cancer / 中国中药杂志

Network Meta-analysis was used to evaluate the efficacy and safety of different oral Chinese patent medicines combined with transcatheter arterial chemoembolization(TACE) in the treatment of primary liver cancer. Randomized controlled trials of oral Chinese patent medicines for primary liver cancer were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and EMbase databases from inception to May 2020. According to the Cochrane recommendation standard, the quality of the included articles was evaluated, and the data were analyzed by RevMan, R software and GeMTC software. A total of 10 kinds of oral Chinese patent medicines and 68 RCTs were included. Network Meta-analysis results showed that: as compared with TACE alone, 10 kinds of oral Chinese patent medicines combined with TACE showed advantages in effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence. In the pairwise comparison of oral Chinese patent medicines, the results showed that Cidan Capsules were superior to Jinlong Capsules and Xihuang Pills in 1-year survival rate. According to the probabi-lity ranking results: Shenyi Capsules and Ganfule were more obvious in improving the effective rate; Cidan Capsules and Shenyi Capsules were more effective in improving the 1-year survival rate; Pingxiao Capsules and Shenyi Capsules had better efficacy in improving 2-year survival rate; Huaier Granules and Shenyi Capsules had better efficacy in improving the quality of life; Huisheng Oral Liquid and Ganfule were more effective in reducing the incidence of adverse reactions(such as nausea, vomiting and leukocytosis). The current evidence showed that oral Chinese patent medicine combined with TACE was superior to TACE alone in efficacy and safety. In terms of the effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence, the optimal treatment measures were Shenyi Capsules, Cidan Capsules, Pingxiao Capsules, Huaier Granules and Huisheng Oral Liquid in turn. However, due to the limitations of the research, the current level of evidence is not high, and clear conclusions and evi-dence strength still need to be further verified and improved by high-quality researches.

[Molecular regulatory mechanisms of hypoxia-inducible factor and interventional effect of Chinese herbal medicine].

Hypoxia-inducible factors(HIFs)are the key transcription factors that sense and regulate cellular oxygen concentration in vivo. HIF-1 is composed of 2 subunits,α and ß,in which,the molecular regulatory mechanism of HIF-1α involves the main processes of its degradation and activation. The degradation of HIF-1α is regulated by oxygen-dependent pathways,including "von hippel-lindau protein(pVHL)-dependent pathway" and "pVHL-independent pathway". The activation of HIF-1α is regulated by oxygen-independent pathways,including mammalian target of rapamycin(mTOR)/eukaryotic initiation factor 4 E-binding protein 1(4 EBP1)/HIF-1α pathway,phosphatidylinositol 3-kinase(PI3 K)/proteirrserinc-threonine kinases(Akt)/HIF-1α pathway and silent information regulator1(Sirt1)/HIF-1α pathway. In recent years,based on the molecular regulatory mechanism of HIFs,Roxadustat,a new drug for the treatment of renal anemia has been developed. Besides, some macromolecular substances with similar pharmacological effect to HIFs have been found in the extracts from Chinese herbal medicine(CHM),such as emodin,notoginseng triterpenes,honokiol and clematichinenoside. These natural macromolecular substances play the regulatory roles in inflammatory response,epigenetic modification and auto-phagy. It is worth noting that,for common hypoxic-related diseases including diabetic kidney disease,HIFs-mediated "pyroptosis" may be a new target of CHMs for clearing dampness and heat and its representative classical prescriptions(Ermiao Pills)in treating inflammatory injury in cells and tissues.

Phytochemical studies on the plants in the genus have demonstrated a large amount of terpenoids and alkaloids. Modern pharmacological studies have demonstrated cytotoxicity, antivirus, antibacterial, anti-inflammation and other pharmacological activities. In this paper, chemical compositions and biological activities of Trigonostemon genus at home and abroad over the past decade were summarized, in order to provide scientific basis for the further development and utilization of Trigonostemon plants.

An innovative wax-based enteric coating for pharmaceutical and nutraceutical oral products.

In this work, a novel enteric coating based on natural waxes and alginate was reported. Initially, theophylline tablets were coated with emulsified ceresin wax in heated aqueous alginate solution using a fluidised bed coating technology. A coating level of 10% proved sufficient to prevent tablets from uptaking gastric medium (<5%) and produced a delayed release profile that complies to the pharmacopeial criteria of enteric coating release. Then, a wide range of emulsions based on other natural waxes (white beeswax, yellow beeswax, cetyl palmitate, carnauba wax or rice bran wax) yielded coatings with similar disintegration times and release profiles. Interestingly, the ceresin-based coating showed a superior performance at inhibiting acid uptake and enabling highly pH-responsive drug release in comparison to different commercially available GRAS enteric coating products (Eudraguard® Control, Swanlac® ASL10, and Aquateric™ N100). The coating was stable for 6 months at 30 °C and 65% RH. This innovative approach of applying hot O/W emulsion of natural waxes yielded an aesthetically attractive and stable coating with gastric protection and pH-sensitive release properties. The novel coating can be an efficient and promising alternative to overcome the shortcomings of current GRAS grade enteric coating products.

Lycium barbarum Polysaccharide Extracted from Lycium barbarum Leaves Ameliorates Asthma in Mice by Reducing Inflammation and Modulating Gut Microbiota.

This study was designed to explore the impact of Lycium barbarum polysaccharide (LBP) on inflammation and gut microbiota in mice with allergic asthma. Mice were divided into four groups: control group, OVA (ovalbumin) group, Con+LBP group, OVA+LBP group. After 28 days of LBP intervention, mice were euthanized and associated indications were investigated. Histopathological examination demonstrated that LBP reduced lung injury. The results of our current study provide evidence that supplementation with LBP in asthmatic mice decreases TNF, IL-4, IL-6, MCP-1, and IL-17A in plasma and bronchoalveolar lavage fluid (BALF). Sequencing and analysis of gut microbiota indicated that compared with the OVA group, Lactobacillus and Bifidobacterium were increased, but Firmicutes, Actinobacteria, Alistipes, and Clostridiales were decreased in the OVA+LBP group. We also found that gut microbiota were related to inflammation-related factors. Therefore, we speculate that LBP may improve allergic asthma by altering gut microbiota and inhibiting inflammation in mice.

Multi-targeted therapeutic effects of Huangkui Capsules on insulin resistance and urine microalbumin in early diabetic kidney disease patients / 中国中药杂志

To observe the multi-targeted therapeutic effects of Huangkui Capsules(HKC)on insulin resistance(IR)and urine microalbumin in the early diabetic kidney disease(DKD)patients. The case data from the 83 DKD patients at G2 and A2 stage were collected respectively and analyzed retrospectively. According to the different treatment,all patients were divided into the control(A)group(40 cases)and the treated(B)group(43 cases). Among them,the A group patients were received "routine basic treatment";the B group patients were received "routine basic treatment+HKC". For the 2 group patients,firstly,the baseline parameters before receiving the treatment were compared respectively,and then,the changes of the total scores of traditional Chinese medicine(TCM) syndromes and the indicators of IR,urine protein,renal function,blood lipids and safety after receiving the treatment for 8 weeks were compared,respectively. Furthermore,for the all patients,the correlation analysis between IR and urine protein or IR and the total scores of TCM syndromes was carried out,respectively. The results showed that,for the B group patients received "routine basic treatment",their total scores of TCM syndromes,urine protein indicators including urine microalbumin(micro-UAlb) and urine microalbumin/urinary creatinine(UACR),IR indicators including fasting serum insulin(FIN)and homeostasis model assessment of insulin resistance(HOMA-IR)were significantly improved,respectively. For the all DKD patients,before and after the treatment,the main IR indicators(FIN and HOMA-IR)were positively correlated with urine protein indicators(micro-UAlb and UACR). The main IR indicators(FIN and HOMA-IR) were also positively correlated with the total scores of TCM syndromes. In addition,2 treatments had no significant effects on renal function,blood lipids and safety indicators in the all DKD patients. Overall, "routine basic treatment+HKC" can ameliorate IR and reduce urine microalbumin in the early DKD patients. Its therapeutic targets may be not only proteinuria,but also IR,which is the upstream risk factor of proteinuria.

Research on Bayesian fault diagnosis model of traditional Chinese medicine dry granulation based on failure model and effect analysis (FMEA) / 中国中药杂志

This paper aims to construct a Bayesian(BN) fault diagnosis model of traditional Chinese medicine dry granulation based on the failure model and effect analysis(FMEA), effectively control risk factors and ensure the quality of granules.Firstly, the risk ana-lysis of dry granulation process was carried out with FMEA, and the selected medium and high risk factors were taken as node variables to establish corresponding BN network with causality.According to the mathematical reasoning method of probability theory, the model was accurately inferred and verified by Netica, and the granule nonconformance was used as the evidence for reversed reasoning to determine the most likely cause of the failure that affected the granule quality.The BN fault diagnosis model of traditional Chinese medicine dry gra-nulation was established based on the medium and high risk factors of process, prescription and equipment screened out by FMEA, such as roller pressure, raw material viscosity, clearance between rollers in the paper.The fault diagnosis of traditional Chinese medicine dry granulation process was then carried out according to the model, and the posterior probability of each node under the premise of nonconforming granule quality was obtained.This method could provide strong support for operators to quickly eliminate faults and make decisions, so as to improve the efficiency and accuracy for fault diagnosis and prediction, with innovation in its application.
