The status of medication review in addressing drug-related problems of elderly patients in the community / 中国药房

With the increasing aging of our population， the incidence of drug-related problems among elderly patients in the community is gradually increasing. Drug-related problems can lead to an increased incidence of adverse health outcomes such as falls and frailty in elderly patients in the community. Medication review is one of the effective means of addressing drug-related problems. The medication review models in Europe and the United States have been developed for decades to address drug-related problems； medication review model in the United Kingdom focuses on the management of drug therapy for elderly patients in aged care facilities， while the medication review models in the United States and Australia have a broader scope（covering all elderly patients in the community）， and the frequency of medication reviews in the United States and Australia are clearer and more standardized. Compared with the above countries， China’s medication review model has a late start. Our country can learn from the advanced experience of the United Kingdom， the United States， Australia and other countries， actively explore and build a drug review model suitable for China’s national conditions， so as to improve the health level of elderly patients in the community and save social public medical resources.

OBJECTIVE To explore the pharmaceutical care model for elderly patients with drug-related problems （DRPs） based on the comprehensive medication management review （CMMR）， and to observe the effect of pharmaceutical care under the model. METHODS The pharmaceutical care new model for elderly patients was established by concerning CMMR guidelines in Australia. In other words， clinical pharmacists receive medical care through referral by health practitioners and active consultation by patients or their caregivers. Visits were made by a combination of face-to-face and telephone interviews. Follow-up was carried out in the form of outpatient follow-up， telephone follow-up， appointment， and home guidance to know about the treatment of DRPs by healthcare practitioners or patients.Under this model， the occurrence status and classification of DRPs in elderly patients were studied through cross-sectional investigation. The effect of pharmaceutical care was evaluated from the aspects of hospitalization rate， adverse drug reaction （ADR） incidence，medication compliance， the number of medications， blood lipid level， etc.， through self-before-after comparison. RESULTS In this study， a patient-centered， evaluation-intervention-reevaluation closed-loop pharmaceutical care model was formed. Among 317 study subjects， the average number of DRPs was 1.03 （0-7） cases. Compared before and after the intervention， the number of drug types increased from 2.00（0.00，3.00） to 2.00（1.00，3.00）， but the level of low-density lipoprotein cholesterin in patients decreased from 3.48 （2.58， 4.29） mmol/L to 3.11 （2.29，3.81） mmol/L （P＜0.05）. There was no statistical significance in hospitalization rate， ADR incidence within or medication compliance.

Protective effect and mechanism of Astragalus membranaceus and Angelica sinensis compatibility against triptolide-induced hepatotoxicity by regulating Keap1/Nrf2/PGC-1α / 中国中药杂志

This paper aims to investigate the protective effect and mechanism of Astragalus membranaceus and Angelica sinensis before and after compatibility against triptolide(TP)-induced hepatotoxicity. The experiment was divided into a blank group, model group, Astragalus membranaceus group, Angelica sinensis group, and compatibility groups with Astragalus membranaceus/Angelica sinensis ratio of 1∶1, 2∶1, and 5∶1. TP-induced hepatotoxicity model was established, and corresponding drug intervention was carried out. The levels of alanine transaminase(ALT), aspartate transaminase(AST), and alkaline phosphatase(ALP) in serum were detected. Pathological injuries of livers were detected by hematoxylin-eosin(HE) staining. The levels of malondialdehyde(MDA), superoxide dismutase(SOD), glutathione peroxidase(GSH-Px), and reduced glutathione(GSH) in the liver were measured. Wes-tern blot method was used to detect the expression of nuclear factor erythroid 2-related factor 2(Nrf2), Kelch-like ECH-associated protein 1(Keap1), peroxisome proliferator-activated receptor gamma, coactivator-1 alpha(PGC-1α), heme oxygenase-1(HO-1), and NAD(P)H quinone dehydrogenase 1(NQO1) in livers. Immunofluorescence was used to detect the expression of Nrf2 and PGC-1α in livers. The results indicated that Astragalus membranaceus/Angelica sinensis ratio of 2∶1 and 5∶1 could significantly reduce the levels of serum AST, ALT, and ALP, improve the pathological damage of liver tissue, increase the levels of GSH and GSH-Px, and reduce the content of MDA in liver tissue. Astragalus membranaceus/Angelica sinensis ratio of 1∶1 and 2∶1 could significantly improve the level of SOD. Astragalus membranaceus and Angelica sinensis before and after compatibility significantly increased the protein expression of HO-1 and NQO1, improved the protein expression of Nrf2 and PGC-1α, and decreased the protein expression of Keap1 in liver tissue. The above results confirmed that the compatibility of Astragalus membranaceus and Angelica sinensis had antioxidant effects by re-gulating Keap1/Nrf2/PGC-1α, and the Astragalus membranaceus/Angelica sinensis ratio of 2∶1 and 5∶1 had stronger antioxidant effect and significantly reduced TP-induced hepatoto-xicity.

Factors associated with low skeletal muscle index among patients with Crohn's disease

SUMMARY OBJECTIVE: Disease-related skeletal muscle loss is highly prevalent among patients with Crohn's disease. Low skeletal muscle mass lead to disability and interventions to prevent skeletal mass loss as an effective strategy to prevent disability. The aim of this article was to identify the factor associated with skeletal muscle loss of Crohn's disease and seek for management target for the prevention of sarcopenia-related disability. METHODS: Patients with Crohn's disease were divided into low and normal skeletal muscle mass groups based on L3 skeletal muscle index using abdominal CT scans. The clinical and laboratory parameters and colonoscopy were compared between the two groups. Univariate and multivariate regression logistic models were built to identify the prognostic markers of Crohn's disease-associated muscle loss. RESULTS: A total of 191 Crohn's disease patients were enrolled in this study, of whom 116 (60.73%) were detected to have low L3 skeletal muscle index, including 71 (68.26%) males. The multivariate logistic regression analysis showed that age (OR: 1.031, 95%CI: 1.006-1.057), female gender (OR: 2.939, 95%CI: 1.386-6.233), disease duration (OR: 0.988, 95%CI: 0.980-0.996), endoscopic disease activity (simple endoscopic score for Crohn's disease) (OR: 0.923, 95%CI: 0.855-0.996), serum albumin (OR: 1.079, 95%CI: 1.009-1.154), and serum creatinine (OR: 1.037, 95%CI: 1.011-1.063) were associated with L3 skeletal muscle index among Crohn's disease patients. CONCLUSION: The gender, age, and duration of disease were uncontrollable factors associated with muscle loss of Crohn's disease. The treatment target of mucosal healing and improved nutritional status may be beneficial for maintaining muscle mass among Crohn's disease patients.

Anti-hepatocarcinoma HepG2 Cell Mechanism of Jaranol： Based on PI3K/Akt Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo study the in vitro anti-hepatocarcinoma HepG2 cell mechanism of Jaranol. MethodThe methyl thiazolyl tetrazolium （MTT） assay was employed to examine the inhibition of Jaranol （0， 5， 10， 25， 50， 100， 150， 300 μmol·L-1） on HepG2 cell proliferation at different time （24 ， 48 ， 72 h）， annexin V-fluorescein isothiocyante/propidium iodide （Annexin V-FITC/PI） kit to detect the effect of Jaranol （0， 3， 15， 75 μmol·L-1） on HepG2 cell apoptosis， and Western blot to determine the influence of Jaranol on the expression of B-cell lymphoma 2 （Bcl-2） and Bcl-2-associated X protein （Bax） in HepG2 cells. Transcriptome sequencing was performed to analyze the differential expression of genes and changes of related signaling pathways after the treatment of HepG2 cells with Jaranol （15 μmol·L-1）. Real-time PCR was carried out to verify the relative mRNA content of differential genes ［TEK， platelet-derived growth factor receptor α （PDGFRA）， spleen tyrosine kinase （SYK）， phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit gamma （PIK3CG）， Janus kinase 3 （JAK3）， membrane-associated guanylate kinase inverted 2 （MAGI2）］. ResultCompared with the blank group， Jaranol decreased HepG2 proliferation （P<0.05， P<0.01）， increased apoptosis rate of HepG2 cells （P<0.05， P<0.01）， raised Bax expression （P<0.05， P<0.01）， and reduced Bcl-2 expression （P<0.05， P<0.01）. Transcriptome sequencing yielded 59 000 regulated genes， 125 of which showed significantly different expression， with 47 up-regulated and 74 down-regulated. Kyoto Encyclopedia of Genes and Genomes （KEGG） analysis showed that the differential genes related to apoptosis in the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway changed significantly after drug addition. The mRNA expression of TEK， PDGFRA， SYK， PIK3CG， JAK3， and MAGI2 decreased in Jaranol （15 μmol·L-1） group compared with that in the control group （P<0.05）. ConclusionIn vitro cytological experiment verified that Jaranol inhibited the proliferation of HepG2 cells and promoted the apoptosis， possibly by influencing the expression of some differential genes in the PI3K/Akt signaling pathway. The result lays an experimental basis for the follow-up study of the anti-tumor effect of Jaranol， and the further development and utilization of flavonoids.

ObjectiveTo study the effect of flower removal on the content of three alkaloids in different parts of Fritillaria thunbergii from different regions and at different growth stages. MethodThe content of peiminine， peimine， and peimisine in the bulb， root， stem， and leaf of F. thunbergii after flower removal and with flower un-removed at different growth stages and in different regions were determined simultaneously by ultra-performance liquid chromatography-evaporative light scattering detection （UPLC-ELSD） method. The UPLC was conducted on ACQUITY UPLC BEH C18 column （2.1 mm × 150 mm， 1.7 μm） with the mobile phase of 0.02% triethylamine aqueous solution （A） and methanol （B）elution gradient（0-2 min， 45%A； 2-5 min， 45%-25%A； 5-7 min， 25%A； 7-17 min， 25%-10%A； 17-20 min， 10%A）， flow velocity of 0.20 mL·min-1， column temperature 35 °C， sample room temperature of 20 °C， and injection volume of 3 µL. The ELSD was carried out at drift tube temperature 45 °C and with the sprayer parameter of 40%. ResultThe flower removal significantly increased the yield of F. thunbergii. At the budding stage， the alkaloid content in the bulb of F. thunbergii from Ningbo in Zhejiang， Pan'an in Zhejiang， and Nantong in Jiangsu after flower removal were significantly higher than that of flowering un-removal treatment， while it showed no significant difference between the flower removal and un-removal treatments for the samples from Fengjie in Chongqing. At the flowering stage， the alkaloid content in the bulb of F. thunbergii from Nantong in Jiangsu after flower removal was significantly higher than that of flower un-removal treatment， while it showed an opposite trend for the samples from Pan'an in Zhejiang and Fengjie in Chongqing and had no significant difference between the two treatments for the samples from Ningbo in Zhejiang. At the bulb expansion stage， the alkaloid content in the bulb of F. thunbergii from Ningbo in Zhejiang and Pan’an in Zhejiang after flower removal were significantly higher than that of flower un-removal treatment， which was opposite for the samples from Nantong in Jiangsu and had no significant difference between the treatments for the samples from Fengjie in Chongqing. At the harvest stage， except for the samples from Pan'an in Zhejiang， the samples from the rest 3 regions showed decreased alkaloid content in the bulb after flower removal compared with that of flower un-removal treatment. The alkaloid content in the leaf was higher than that in the bulb of F. thunbergii at all growth stages and from different origins. ConclusionFlower removal can increase the yield of F. thunbergii. The alkaloid content in the bulb of F. thunbergii with flower removed was higher than that with flower un-removed at the budding stage， while this trend was reversed at the harvest stage. Both the yield and the alkaloid content of F. thunbergii from Pan'an in Zhejiang were increased by flower removal. The above-ground part of F. thunbergii has a potential development value.

Research Progress on Anti-atherosclerosis Mechanism of Mongolian Medicine / 中国实验方剂学杂志

Atherosclerosis is one of the most common diseases that threaten human health. How to effectively inhibit atherosclerosis， extend the survival time and improve the quality of life has become one of the most urgent issues to be solved clinically. Mongolian medicine， with a long history of managing human diseases， is an important part in traditional Chinese medicine （TCM） and has distinct ethnic characteristics. It has been gradually formed and developed by absorbing some theories of Tibetan medicine， Indian medicine and relevant knowledge of TCM. Mongolian medicine has many advantages， including but not limited to， low toxicity and diverse structure. However， the action mechanism of Mongolian medicine in preventing and managing atherosclerosis has yet to be fully clarified， which has been a major obstacle for further promotion and application of Mongolian medicine in clinical settings. In this review， the up-to-date research findings on Mongolian medicine were collected， analyzed and summarized， and the anti-atherogenic action mechanism of Mongolian medicine were reviewed from the aspects of anti-inflammatory， lipid-lowering， anti-oxidative stress， vascular endothelial cell protection， and inhibition of vascular smooth muscle cell proliferation and migration.

In order to obtain a series of dibenzoylmethane halophenols with strong anti-inflammatory and antioxidant effects targeting CAV-1, twenty-nine target compounds were therefore synthesized by Baker-Ventaraman rearrangement and demethylation reaction, starting from the substituted benzoyl chloride and o-hydroxyacetophenone, and their interactions with CAV-1 were investigated by BLI technique. Their in vitro anti-inflammatory and antioxidant properties were also evaluated. The results showed that compounds A6, A17, A18, and A29 not only specifically bind to CAV-1, but also present strong anti-inflammatory and antioxidant effects. These results suggest that this class of compounds can affect the signaling pathways related to inflammation and oxidative stress by directly acting on CAV-1. In particular, these compounds exhibit the most significantly inhibitory effects on IL-1β and COX-2 release. IL-1β plays a key regulatory role in the development of arthritis. Therefore, it is worth expecting for the application of such compounds in the prevention and treatment of arthritis.

Treatment of HBV Cirrhosis with Fuzheng Huayu Tablet () and Entecavir: Design of a Randomized, Double-Blind, Parallel and Multicenter Clinical Trial / 中国结合医学杂志

BACKGROUND@#Antiviral therapy can lead to regression of fibrosis in chronic hepatitis B (CHB), but it has a limited effect on cirrhosis. Chinese medicines (CMs), particularly Fuzheng Huayu Tablet (, FZHY), have an antifibrotic effect in patients with CHB.@*OBJECTIVE@#To observe the safety and efficacy of adjunctive FZHY in patients with hepatitis B virus (HBV) cirrhosis, this study was designed as a randomized, placebo-controlled, double-blind, parallel assignment, multicenter trial at 20 centers in China. The total 700 naive patients will be enrolled with compensate cirrhosis due to HBV, and randomly assigned into 2 groups, receiving entecavir (0.5 mg, daily) and FZHY placebo (1.6 g, 3 times a day), or entecavir (0.5 mg, daily) and FZHY (1.6 g, 3 times a day), respectively. The primary endpoint was histological improvement at week 48. The secondary outcome is the decline values of liver fibrosis using the noninvasive methods from baseline to week 48 in each arm of the study. Adverse events such as stomach upset, headache, fatigue, dizziness, nausea will be strictly recorded.@*DISCUSSION@#Through this study, we hope to generate a solid evidence for the therapeutic strategy of HBV cirrhosis with a combination of anti-viral such as ETV and anti-fibrotic herbal product such as FZHY. Protocol version: Version 1.3, Date: 2014.12.4.@*TRIAL REGISTRATION NUMBER@#NCT02241590.

Taenia saginata Infection Misdiagnosed as Acute Cholecystitis in a Tibetan Patient, in China

The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.

Efficacy and safty of Dexamethasone intravitreal implant in noninfectious refractory uveitis / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM:To evaluate the efficacy and safety of dexamethasone intravitreal implant for the treatment of noninfectious refractory uveitis and analyze its influence on application and dose of systemic corticosteroids and immunosuppressive agent.<p>METHODS: This was a retrospective, case series study conducted between January 2018 and September 2019, the patients with noninfectious refractory uveitis and treated with intravitreal implantation of dexamethasone intravitreal implant were included. The best corrected visual acuity(BCVA), central retinal thickness(CRT), vitreous haze score, and intraocular pressure(IOP)at 1mo, 2mo, 4mo and 6mo after the implantation of dexamethasone intravitreal implant were compared with the baseline. Meanwhile, the dosage of corticosteroids and immunosuppressive agent used before and after the implantation of dexamethasone was also evaluated. The data was displayed as mean±standard deviation and analyzed using the paired <i>t</i>-test.<p>RESULTS: A total of 19 patients(21 eyes)were included in the present study. The mean baseline BCVA of the included patients was 0.671±0.469, while the mean CRT was 369.667±177.100μm, and the mean intraocular pressure(IOP)was 14.252±3.181mmHg. One month, 2mo, 4mo and 6mo after the injection of Ozrudex, BCVA was significantly improved compared with the baseline(<i>P</i><0.05), while the CRT and vitreous haze score were significantly reduced(<i>P</i><0.05,<i> P</i><0.05). During the follow-up period, IOP of several patients significantly increased, but normal IOP can be observed at the end of the follow-up for all included patients. At baseline, 6 patients(6 eyes)were treated with systemic corticosteroids with an average dosage of 35.8mg/d, while only 2 patients were treated with systemic corticosteroids at the end of the 6mo follow-up(5mg/d). Apart from 3 eyes with Behcet's disease which showed recurrence of macular edema between 4-6mo, no other patient underwent that. <p>CONCLUSION: Dexamethasone intravitreal implantis considered to be a safe and effective approach for non-infectious refractory uveitis which can reduce systemic medication, with significant improvement of BCVA, reduction of CRT, vitreous haze score and the dosage of systemic corticosteroids.
