Kochiae Fructus, the Fruit of Common Potherb Kochia scoparia (L.) Schrad: A Review on Phytochemistry, Pharmacology, Toxicology, Quality Control, and Pharmacokinetics.

Kochiae Fructus (KF) is the fruit of an annual potherb Kochia scoparia (Linn.) Schrad and has been traditionally used for the treatment of diseases in the skin, eyes, and urinary tract for thousands of years in China. Recent studies have showed its anti-inflammatory, antifungal, antiallergic, and antipruritogenic effects to clarify the mechanisms of these actions. Meanwhile, its other effects, such as anticancer, hypoglycemic, and hepatoprotective effects, also have been reported. The achievement of these therapeutic effects is contributed by its chemical constituents. A total of 153 compounds have been identified in KF, mainly including triterpenoids, flavonoids, carbohydrates, amino acids, organic acids, and essential oils. Momordin Ic is the representative triterpene glycoside compound, which is used as a phytochemical marker for the quality control of Kochiae Fructus. The research on toxicity is insufficient, and only one article reported that the LD50 was 7.15 ± 0.03 g/kg for water extract of KF after oral administration in KM mice. In addition, the pharmacokinetic study was carried out on momordin Ic with linear pharmacokinetic characteristics. Above all, this review provides comprehensive information about Kochiae Fructus and may provide the theoretic foundation of its clinical application and further development.

Anti-inflammatory effect of traditional Chinese medicine preparation Penyanling on pelvic inflammatory disease.

ETHNOPHARMACOLOGICAL RELEVANCE: Penyanling is made up of Smilacis Glabrae Rhizoma (SG, from Smilar glabra Roxb.), Angelicae Sinensis Radix (AS, from Angelica sinensis (Oliv.) Diels), Salviae Miltiorrhizae Radix et Rhizoma (SM, from Salvia miltiorrhiza Bunge), Sargentodoxae Caulis (SC, from Sargentodoxa cuneata (Oliv.) Rehd.et Wils.), Linderae Radix (LR, from Lindera aggregata (Sims) Kosterm.), Paeoniae Radix Rubra (PR, from Paeonia lactiflora Pall.), Sparganii Rhizoma (SR, from Sparganium stoloniferum (Graebn.) Buch.-Ham.), Corydalis Rhizoma (CoR, from Corydalis yanhusuo W. T. Wang), Cyperi Rhizoma (CyR, from Cyperus rotundus Linn.), Glycyrrhizae Radix et Rhizoma (GR, from Glycyrrhiza uralensis Fisch.), and Patrinia Scabiosaefolia (PS, from Patrinia scabiosaefolia Fisch. ex Trev.) recorded in Chinese Pharmacopoeia. It has been used on pelvic inflammatory disease (PID) for more than twenty years. AIM OF THE STUDY: This study was carried out to illustrate its pharmacological action and clarify its substantial composition. MATERIALS AND METHODS: The anti-inflammatory effects of Penyanling were studied on a PID rat model and a lipopolysaccharides (LPS)-stimulated THP-1 cell line. Histological changes and levels of inflammatory factors in the uterine tube of the PID rat were examined. Levels of nuclear factor-kappa B (NF-κB) in the nuclear of THP-1 cells and NF-κB, IκB-α, and FPR2 in the cytoplasm were tested by Western blot analysis. Substances within Penyanling were scanned with liquid chromatography-quadrupole-time of flight-mass spectrometry (LC-Q-TOF-MS). The contents of total flavonoids, phenolics, and saponins were quantified. RESULTS: The anti-inflammatory effects of Penyanling were observed on PID rats, such as suppressing the infiltrations of lymphocytes and neutrophils in the uterine tube, decreasing the release of interleukin (IL)-1ß, IL-6, IL-8, and monocyte chemotactic protein (MCP)-1, and promoting the production of lipoxin A4 (LXA4). On the other hand, Penyanling regulated the activity of NF-κB signal pathway on the LPS-stimulated THP-1 cell line, which suggested the potential mechanism of its anti-inflammatory effect. Besides, it could promote the expression of formyl peptide receptor 2 (FPR2), which suggested its effect on enhancing the resolution of inflammation. Seventy-six substances were identified by their accurate molecular weights, mass fragment patterns, retention times, and standards if available. Most of these substances were flavonoids, phenolics, saponins, and alkaloids. The contents of total flavonoids, phenolics, and saponins within Penyanling were 0.186, 1.371, and 4.321 mg/mL, respectively. CONCLUSION: Penyanling showed an anti-inflammatory effect on PID, and its potential mechanism involved suppressing NF-κB signal pathway and promoting the resolution of inflammation. The main substances within it were flavonoids, phenolics, saponins, and alkaloids.

Siderophore Production by Rhizosphere Biological Control Bacteria Brevibacillus brevis GZDF3 of Pinellia ternata and Its Antifungal Effects on Candida albicans.

Brevibacillus brevis GZDF3 is a gram-positive, plant growth-promoting rhizosphere bacterium (PGPR) isolated from the rhizosphere soil of Pinellia ternata (an important herb in traditional Chinese medicine). The GZDF3 strain produces certain active compounds, such as siderophores, which are the final metabolite products of non-ribosomal peptide synthetase (NRPS) and independent non-ribosomal peptide synthetase (NIS) activity. With the present study, we attempted to investigate the siderophore production characteristics and conditions of Bacillus sp. GZDF3. The antibacterial activity of the siderophores on pathogenic fungi was also investigated. Optimal conditions for the synthesis of siderophores were determined by single factor method, using sucrose 15 g/l, asparagine 2 g/l, 32°C, and 48 h. The optimized sucrose asparagine medium significantly increased the production of siderophores, from 27.09% to 54.99%. Moreover, the effects of different kinds of metal ions on siderophore production were explored here. We found that Fe3+ and Cu2+ significantly inhibited the synthesis of siderophores. The preliminary separation and purification of siderophores by immobilized-metal affinity chromatography (IMAC) provides strong antibacterial activity against Candida albicans. The synergistic effect of siderophores and amphotericin B was also demonstrated. Our results have shown that the GZDF3 strain could produce a large amount of siderophores with strong antagonistic activity, which is helpful in the development of new biological control agents.

Immunological modulation effects of an acid Epimedium polysaccharide on immune response in chickens.

The purpose of the present study is to investigate the immunological activities of EPS-1 in the non-specific immune response and specific immune response of chickens. In vitro, the results showed that EPS-1 could increase the proliferation and cytokine secretion (IL-2, IL-4, IFN-γ and TNF-α) of spleen lymphocytes, expression of key surface molecules (MHC II, CD11c, CD40 and CD86) and cytokine secretion (TNF-α and IL-10) of matured chBM-DCs, phagocytic rate of matured chBM-DCs, and enhance the maturation and stimulating capacity of chBM-DCs. In vivo, EPS-1 could also prompt the HI antibody titer, boost the peripheral lymphocyte proliferation, enhance the release of cytokine products in blood (IFN-γ, IL-4 and IL-2) and duodenum (IL-17 and sIgA) of chickens. These results indicated that EPS-1 may have the potential as a powerful immune adjuvant in the treatment of chicken diseases.

Value of pulmonary ventilation score in evaluating extravascular lung water of patients with acute respiratory distress syndrome / 第二军医大学学报

Objective To discuss the value of pulmonary ventilation score in evaluating the extravascular lung water (EVLW) of patients with acute respiratory distress syndrome (ARDS). Methods We retrospectively collected the clinical data of 32 patients with ARDS, who were treated in the Department of Critical Care Medicine of Seventh People’s Hospital of Shanghai University of Traditional Chinese Medicine from Jun. 2015 to Feb. 2017 and improved within 7 days. The total pulmonary ventilation score, extravascular lung water index (EVLWI), oxygenation index (PaO2/FiO2), and central venous pressure (CVP) of patients at admission and after treatment for 7 d were recorded. The correlations between total pulmonary ventilation score and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, EVLWI, oxygenation index and CVP were analyzed. Results The APACHE Ⅱ score, total pulmonary ventilation score and EVLWI of the ARDS patients after treatment for 7 d were significantly decreased compared with those at admission, and the oxygenation index was significantly increased (all P0.01). The pulmonary ventilation score was positively correlated with the APACHE Ⅱ score, EVLWI and CVP (r＝0.95, 0.95, 0.64; all P0.01), and was negatively correlated with the oxygenation index (r＝－0.94, P0.01). Conclusion Pulmonary ventilation score can effectively evaluate the EVLW of patients with ARDS, and can be used as an effective supplement for EVLW monitoring in patients with ARDS in addition to pulse indicator continous cadiac output.

[Risk factors for congenital anal atresia].

OBJECTIVE: To investigate the risk factors for the development of congenital anal atresia in neonates. METHODS: A total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia. RESULTS: The univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086). CONCLUSIONS: Infection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

A randomized controlled trail of combination therapy of neuromuscular electrical stimulation and balloon dilatation in the treatment of radiation-induced dysphagia in nasopharyngeal carcinoma patients.

Dysphagia is a most common complication induced by radiotherapy in nasopharyngeal carcinoma (NPC) patients. This randomized controlled trail (RCT) was performed to evaluate the therapeutic effect of combination therapy of neuromuscular electrical stimulation (NMES) and balloon dilatation in the treatment of radiation-induced dysphagia in NPC patients. Sixty NPC patients with radiation-induced dysphagia were assigned to either the combination rehabilitation group (treatment group) or the routine rehabilitation group (control group) at random. Both groups were subjected to routine rehabilitation treatment, while the combination rehabilitation group also received combination therapy of NMES and balloon dilatation for 4 months. The water swallow test (WST) and videofluoroscopic swallowing study (VFSS) were used to evaluate the severity of dysphagia. The treatment group showed a significant improvement in swallowing function when compared with the control group. When the WST was used, the efficacy rate (percentage of patients with excellent and effective results) of treatment group was higher than that of control group (90.1 vs. 76.3%), and the difference was statistically significant (χ(2) = 8.55, p = 0.036). When the VFSS was used, the videofluoroscopy results in our study showed that the values of oral transit time (OTT), swallow reaction time (SRT), pharyngeal transit time (PTT) and laryngeal closure duration (LCD) in treatment group were notably improved when compared with those in control group. In conclusion, combination rehabilitation treatment can improve swallow function in the treatment of radiation-induced dysphagia in NPC patients.

Ypsilandra thibetica belongs to the family Liliaceae. Its whole plant has the medicinal functions of heat-clearing and detoxifying, relieving congestion and other effects, and is used as the folk medicine to cure scrofula, dysuria embolism and other symptoms. Previous chemical studies revealed that its major and active ingredient is steroidal saponin. Up to now, more than fifty steroidal saponins, mainly composed of spirostan and furostanol types, have been described. Pharmacological and clinical studies have demonstrated that Y. thibetica has anti-tumor, uterine contractions, hemostatic and antibacterial activities, in particular for the treatment of a variety of gynecological hemorrhagic diseases. In an effort to provide references for the advanced research and development of this species, this paper summarized the research progress on its pharmacognosy, including botany and authentication, its isolated secondary metabolites, biological activities and pharmacological applications. In addition, some advantages of this species which could be potentially used as a substitute for Paridis Rhizoma, one of ingredients of the well-known drug "Yunnan Baiyao", together with the future prospect are also briefly included.

A meta-analysis of the efficacy of acupuncture in treating dysphagia in patients with a stroke.

BACKGROUND: Dysphagia, or deglutition difficulty, is a common manifestation in patients with a stroke and its management is an important aspect of rehabilitation. Acupuncture, a complementary and alternative therapy, is the subject of growing public interest for treatment of stroke. OBJECTIVE: A meta-analysis was performed to study the effect of acupuncture for treatment of dysphagia in patients affected by a stroke. METHODS: Randomised controlled trials (RCTs) comparing acupuncture treatment with non-acupuncture treatment of dysphagia in patients with a stroke were identified from the databases of PubMed, Embase, Cochrane Library and CBM disc (China Biological Medicine Database). Eligible investigations were included and data on the effectiveness of acupuncture were extracted and synthesised by meta-analysis using RevMan 5.1.4. Results were expressed as OR for dichotomous data; 95% CIs were also calculated. RESULTS: Seventy-two RCTs (3208 patients in the treatment group and 2926 patients in the control group) were identified. Details of randomisation and blinding were not reported and information on withdrawals and dropouts was missing in most of included reports. Meta-analysis showed that the effectiveness of treatment in the group receiving acupuncture was higher than that in the non-acupuncture group (OR=5.17, 95% CI 4.18 to 6.38; p<0.00001). However, the study quality was generally low and of insufficient quality to make recommendations about using acupuncture in the rehabilitation of patients with dysphagia due to stroke. CONCLUSIONS: Acupuncture might be beneficial in the rehabilitation of patients with dysphagia caused by stroke, and the evidence justifies future high-quality studies.

Efficacy of intramuscular matrine in the treatment of chronic hepatitis B.

BACKGROUND: Hepatitis B virus (HBV) infection, a global public health problem, is the leading cause of cirrhosis and hepatocellular carcinoma (HCC) worldwide. There are more than 350 million HBV carriers in the world and up to one million die annually due to hepatitis B associated liver disease. So far no optimal treatment is available for patients with chronic hepatitis B. In the paper we investigated the efficacy of intramuscular matrine in the treatment of chronic hepatitis B. METHODS: One hundred and twenty patients with chronic hepatitis B were randomly divided into matrine treatment group (n=60) and control group (n=60). The patients of the matrine group were given intramuscularly with matrine (an alkaloid extracted from a traditional Chinese herb Radix Sophorae Flavescentis by Guangzhou Ming Xing Pharmaceutical Factory, Guangzhou, China) of 100 mg daily for 90 days in addition to conventional liver-protective drugs including glucurone, inosine, compound vitamin B and caryophyllin. The control group received conventional liver-protective drugs alone. Clinical manifestations and laboratory parameters including liver biochemistry and serum hepatitis B virus markers were monitored before and after treatment in the two groups. RESULTS: Significant differences were seen between the two groups in terms of improvement of clinical symptoms and signs, recovery of liver functions, and serum conversion from hepatitis Be antigen to HBe antibody and from positive to negative serum HBV DNA (P<0.05-0.01). The result of the matrine group was more marked than that of the control group. Serious side-effects were not observed except mild pain at the site of injection of matrine in a few patients. CONCLUSION: These results indicate that intramuscular matrine may be an economical, efficacious, safe drug for the treatment of chronic hepatitis B.
