- Abstract：Chinese medicine (CM) has been used in clinical treatment for thousands of years in China, Japan, Korea, and other countries. CM is at present attracting many attentions around the world for reproductive health care and disease prevention, including treatment of female infertility. This review focuses on the CM treatment for female infertility patients, and supplies a summary on the efficacy, safety, and mechanism of some Chinese herbal medicines, herbal medicine-derived active compounds, and acupuncture. A large number of researches have reported that CM could alleviate or even cure female infertility by regulating hormone, improving reproductive outcome of in vivo fertilization, affecting embryonic implantation, curing polycystic ovarian syndrome, endometriosis, pelvic inflammatory disease, relieving mental stress, and regulating immune system. Meanwhile, a few studies claimed that there was little adverse reaction of CM in randomized controlled trials. However, up to present there is a lack of adequate evidences with molecular mechanistic researches and randomized controlled trials to prove the CM as an effective and safe treatment for infertility. Thus, utility of CM as a complementary medicine will be a feasible method to improve the outcome of female infertility treatment.Keywords：female infertility;Complementary Medicine;Chinese Medicine;combination therapy

Published：2021-08-27 - Abstract：To identify key symptoms of two major syndromes in chronic hepatitis B (CHB), which can be the clinical evidence for Chinese medicine (CM) doctors to make decisions. Standardization scales on diagnosis for CHB in CM were designed including physical symptoms, tongue and pulse appearance. The total of 695 CHB cases with dampness-heat (DH) syndrome or Pi (Spleen) deficiency (SD) syndrome were collected for feature selection and modeling, another 275 CHB patients were collected in different locations for validation. Key symptoms were selected based on modified information gain (IG), and 5 classifiers were applied to assist with models training and validation. Classification accuracy and area under receiver operating characteristic curves (AUC) were evaluated. (1) Thirteen DH syndrome key symptoms and 13 SD syndrome key symptoms were selected from original 125 symptoms; (2) The key symptoms could achieve similar or better diagnostic accuracy than the original total symptoms; (3) In the validation phase, the key symptoms could identify syndromes effectively, especially in DH syndrome, which average prediction accuracy on 5 classifiers could achieve 0.864 with the average AUC 0.772. The selected key symptoms could be simple DH and SD syndromes diagnostic elements applied in clinical directly.

Published：2021-08-27 - Abstract：To investigate the chemical transformation of volatile compounds in sulfur-fumigated Radix Angelicae Sinensis. A comprehensive two-dimensional gas chromatography (GC×GC) and high-resolution time-of-flight mass spectrometry (HR-TOF/MS) with colorized fuzzy difference (CFD) method was used to investigate the effect of sulfur-fumigation on the volatile components from Radix Angelicae Sinensis. Twenty-five compounds that were found in sun-dried samples disappeared in sulfur-fumigated samples. Seventeen volatile components including two sulfur-containing compounds were newly generated for the first time in volatile oils of sulfur-fumigated Radix Angelicae Sinensis. The strategy can be successfully applied to rapidly and holistically discriminate sun-dried and sulfur-fumigated Radix Angelicae Sinensis. GC×GC-HR-TOF/MS based CFD is a powerful and feasible approach for the global quality evaluation of Radix Angelicae Sinensis as well as other herbal medicines.Keywords：Radix Angelicae Sinensis;comprehensive two-dimensional gas chromatography and high-resolution time-of-flight mass spectrometry;colorized fuzzy difference;volatile components

Published：2021-08-27 - Abstract：To observe the effects of Huannao Yicong Formula (还脑益聪方, HYF) on learning and memory and it’s regulating effect on γ-secretase related anterior pharynx defective 1 (APH-1), presenilin enhancer-2 (PEN-2) signaling pathway, so as to discuss and further clarify the mechanism of HYF on Alzheimer’s disease. Sixty APP/PS1 transgenic mice, randomly allocated into 4 groups, the model group, the donepezil group (0.65 mg/kg), HYF low-dose group (HYF-L, 5.46 g/kg) and HYF high-dose group (HYF-H, 10.92 g/kg), 15 for each group. Another 15 C57BL/6J mice with the same age and same genetic background were allocated into the control group, proper dosage of drugs or distilled water were given by intragastric administration once daily for 12 weeks. After 12 weeks of administration, the learning and memory abilities of mice in each group was evaluated by the morris water maze test, amyloid precursor protein (APP), Aβ1-40 and Aβ1-42 levels in hippocampus were detected by enzyme-linked immunosorbent assay, γ-secretase was detected by dual luciferase assaying, the levels of APH-1a, hypoxia-inducible factor 1α (HIF-1α), cAMP response element-binding protein (CREB) and PEN-2 and their mRNA expression was measured by Western blot and real-time polymerase chain reaction. HYF can ameliorate learning and memory deficits in APP/PS1 transgenic mice by decreasing the escape latency, improving the number of platform crossing and swimming speed (P<0.01, P<0.05). HYF can decrease the levels of APP, Aβ1-40, Aβ1-42 and the activity of γ-secretase in hippocampus of Alzheimer’s disease model mice. HYF can down-regulate the levels of CREB and PEN-2 and the expression of their mRNA. HYF can improve the learning and memory ability by inhibiting the activity of γ-secretase through the CREB/PEN-2 signaling pathway, and this may be one of the therapeutic mechanisms of HYF in Alzheimer’s disease.Keywords：Huannao Yicong Formula;Alzheimer’s disease;γ-secretase;β-amyloid

Published：2021-08-27 - Abstract：To investigate the effects of Huaiqihuang Granules (槐杞黄颗粒, HQH), a mixture of Chinese herbs including Trametes robiniophila Murr, Fructus Lycii and Polygonatum sibiricum, on adriamycininduced nephropathy (ADRN) in rats and its underlying mechanisms. Rats with ADRN were divided into four groups: the sham group, the model group (distilled water), the low-dose HQH-treated (2 g/kg) group, and the high-dose HQH-treated (4 g/kg) group. Body weight and 24-h urinary protein (Upro) were checked every week. After 5-week intervention, at the end of the study, the rats were sacrificed and blood samples were collected for examination of biochemical parameters, including glomerular morphological makers, podocyte shape, cellular apoptosis, expressions of nephrin, inflammatory and apoptosis markers. HQH ameliorated the rat’s general status, proteinuria, renal morphological appearance and glomerulosclerosis. The decreased expression of nephrin in ADRN rats was increased by HQH, as well as the impaired podocyte foot process fusion. Cytosolic levels of p65 and inhibitor of nuclear factor κBα (IκBα) were decreased in ADRN rats, and recovered by the treatment of HQH. Consistently, the induced expression of tumor necrosis factor α (TNF-α), phosphorylated nuclear factor κB p65 (p-NFκB p65) and IκBα in ADRN were markedly suppressed by HQH. In addition, induction of Bax, cleaved caspase-3 and cytochrome C in ADRN rats were suppressed by HQH, indicating the amelioration of apoptosis. HQH could ameliorate renal impairments in ADRN rats by increasing nephrin expression, inhibiting NF-κB signaling pathway via the down-regulation of p-NF-κB p65 and p-IκBα, and suppression of glomerular and tubular apoptosis.Keywords：adriamycin-induced nephropathy;Huaiqihuang Granules;nephrin;nuclear transcription factor kappa B;apoptosis;Chinese Medicine

Published：2021-08-27 - Abstract：To explore the effects of bufalin on inhibiting proliferation, up-regulating methylation of Wilm’ tumor 1 gene (WT1) as well as its possible mechanisms in human erythroid leukemic (HEL) cells. The HEL cells were treated with bufalin at various concentrations to observe cellular morphology, proliferation assay and cell cycle. The mRNA and protein expression levels of WT1 were detected by reverse transcription polymerase chain reaction (RT-PCR), Western blot and immunocytochemistry, DNA methylation of WT1 and protein expression levels of DNA methyltransferase 3a (DNMT3a) and DNMT3b were analyzed by methylation-specific PCR, and Western blot respectively. The bufalin was effective to inhibit proliferation of HEL cells in a dose-dependent manner, their suppression rates were from 23.4%±2.1% to 87.2%±5.4% with an half maximal inhibit concentration (IC50) of 0.046 μmol/L. Typical apoptosis morphology was observed in bufalin-treated HEL cells. The proliferation index of cell cycle decreased from 76.4%±1.9% to 49.7%±1.3%. The expression levels of WT1 mRNA and its protein reduced gradually with increasing doses of bufalin, meanwhile, the methylation status of WT1 gene changed from unmethylated into partially or totally methylated. While, the expression levels of DNMT3a and DNMT3b protein gradually increased by bufalin treatment in a dose-dependent manner. Bufalin can not only significantly inhibit the proliferation of HEL cells and arrest cell cycle at G0/G1 phase, but also induce cellular apoptosis and down-regulate the expression level of WT1. Our results provide the evidence of bufalin for anti-leukemia, its mechanism may involve in increasing WT1 methylation status which is related to the up-regulation of DNMT3a and DNMT3b proteins in erythroid leukemic HEL cells.Keywords：bufalin;human erythroid leukemic cells;Wilm’s tumor 1 gene;methylation;DNA methyltransferase 3a;DNA methyltransferase 3b

- Abstract：To study the efficacy of Chinese medicine (CM) on isolated systolic hypertension. Seven electronic databases were searched for randomized controlled trials (RCTs) published until August 2015. Subgroup analyses and meta-analysis were performed to assess the efficacy and safety of the included studies. A total of 24 studies, including 2,096 patients (1,058 patients in the intervention group and 1,038 in the control group), were evaluated in the final analysis. Compared with a conventional therapy used alone, CM as additional intervention was more effective on systolic blood pressure [mean difference (MD)=–0.66, 95% confidence interval (CI)=(–0.97,–0.36), P<0.00001] and significantly diminished the pulse pressure [MD=–7.49, CI=(–12.69,–2.29), P<0.00001]. However it showed no additional benefit on diastolic blood pressure [MD=1.16, CI=(0.02, 2.29), P=0.87]. Adverse events were not explicitly reported in most RCTs. CM might be a promising approach for the elderly with isolated systolic hypertension, while the evidence for CM employed alone was insufficient. Considering the inherent limitations of the included studies, larger high-quality RCTs with extensive follow-up should be performed to validate our findings in the future.Keywords：Chinese Herbal Medicine;isolated systolic hypertension;meta-analysis;systematic review;randomized controlled trial

Published：2021-08-27 - Abstract：To systematically evaluate the clinical effectiveness and safety of Danshen Injection (丹参注射液, DS) as one adjuvant treatment for conventional therapy with Western medicine (WM) for unstable angina pectoris (UAP). Using literature databases, a thorough and systematic retrieval of randomized controlled trials (RCTs) comparing DS plus WM with WM was conducted from inception to April 2015. The extracted data from included studies was analyzed by Review Manager 5.2 software. The Cochrane risk of bias tool was used to assess the quality of included studies, and Begg’s and Egger’s tests conducted by Stata 12.0 were used to evaluate the potential presence of publication bias. A total of 17 RCTs, which involving 1,433 participants, were identified and reviewed. The meta-analysis indicated that the combined use of DS and WM was significantly superior to WM alone for UAP in terms of the total effectiveness rate of angina pectoris [risk ratio (RR) =1.23, 95% confidence interval (CI): 1.17, 1.29, P<0.01] and the total effectiveness rate of electrocardiogram (ECG) [RR=1.18, 95%CI: 1.06, 1.30, P=0.001]. Additionally, DS could also further reduce the content of fibrinogen, adjust blood lipid level, correct T wave inversion, and so on. Fifteen adverse drug reactions were reported in two studies, Four of which appeared in the experimental group. Based on the systematic review, the combined use of DS and WM was more effective than WM alone, it can be further widely used in clinic, however, there was no exact conclusion for its safety.Keywords：Danshen Injection;unstable angina pectoris;systemic review;meta-analysis

- Abstract：It is very common to use Chinese medicine (CM) combined with Western medicine (WM) in clinical practice. The appropriate combination of CM with WM can reduce toxicity and enhance effects in order to make the best use of advantages and bypass the disadvantages. However, an inappropriate combination can not only affect the curative effect but even cause death. Therefore, strengthening the complementary advantages of the CM and WM to improve the therapeutic efficacy and reduce side effects has become an important research topic of clinical medicine and pharmacy. Many researchers try to clarify the effects of combining CM with WM on therapeutic efficacy and absorption, distribution, metabolism and excretion by pharmacodynamics and pharmacokinetics studies, providing evidence for clinical application. This review focuses on the new developments in the pharmacodynamics and pharmacokinetics of the combination of CM with WM in order to give references for clinical treatment.Keywords：combination of Chinese and Western medicine;pharmacodynamics;pharmacokinetics
