Niigata Prefecture is suffering from a chronic shortage of physicians. The 2000 statistics shows the number of physicians in active service is 162.5 for 100,000 population. This ranks the prefecture 40th among all the 47 administrative divisions of Japan (Average : 191.6 physicians). In the area including Ojiya, where our hospital is located, the number of physicians per 100,000 population works out at 124.5. A lack of physicians poses a serious problem. It is extremely difficult to maintain the quality of medical treatment and meet emergencies. As one of the countermeasures, the Niigata Prefectural Federation of Agricultural Cooperatives for Health and Welfare has made a network of seven hospitals in the Chuetsu area. The network is functioning well between our hospital and the surrounding four hospitals-Nagaoka Chuo General Hospital (Nagaoka), Nakajo Hospital and 2nd Nakajo Hospital (Tokamachi) and Kariwa-gun General Hospital (Kashiwazaki) because of favorable geographic conditions. Our hospital accepts psychiatric patients from 2nd Nakajo Hospital who need surgical treatment. Although our hospital does not have a psychiatric department, we accept those patients and have obtained good results.

To compare the clinical efficacy among different acupuncture and moxibustion therapies on stable angina pectoris (SAP) of coronary heart disease by means of network Meta-analysis. The articles of randomized controlled trial (RCT) for SAP of coronary heart disease treated with acupuncture and moxibustion therapies were searched from PubMed, Web of Science, Cochrane Library, CNKI, Wanfang database and VIP database from May 1, 2002 to May 1, 2022. The quality of them was assessed with the risk of bias assessment tool of Cochrane 5.3, and the network Meta-analysis was undertaken with Stata 13.1 software. A total of 29 articles were included with the acupuncture and moxibustion therapies involved, e.g. acupuncture, acupoint application and moxibustion. In comparison with the simple routine western medication, the effective rate was better on SAP treated with the combined treatments, in which, acupoint application, moxibustion, acupuncture and intradermal needling were combined with routine western medication (P<0.05). Of those combined treatments, the combination of the acupoint application with routine western medication had high probability, suggesting the optimal regimen (area under the curve [SUCRA]=0.711, P<0.05). The effective rate of acupuncture combined with routine western medication for ECG improvement was better than that of routine western medication (P<0.05), and such combined treatment was high in probability, underlying its optimal treatment (SUCRA=0.800, P<0.05). Combined with routine western medication, acupuncture, acupoint application, moxibustion and intradermal needling all improve the clinical efficacy on SAP of coronary heart disease. But, with different outcomes considered, the optimal treatments may be different. It needs more multi-central and large-sample randomized controlled trials to validate these results.

Background and Objectives:
Type 2 diabetes mellitus (T2DM) is a global health concern affecting more than 400 million people worldwide. Diabetic neuropathy, nephropathy, retinopathy, and cardiovascular complications lead to debilitating effects to patients. To prevent these, the treatment goal is to lower the blood sugar levels and maintain at a normal range which is achieved through conventional treatments like insulin and oral hypoglycemic agents. However, the high cost of these medications implicates patient treatment outcomes. Hence, alternatives are sought for including the use of herbal medicines. Momordica charantia (MC) and Lagerstroemia speciosa (LS) are common herbal medicines used to manage T2DM. In the Philippines, these herbal preparations are validated for their glucose lowering effects and are commonly found in combination in food supplements. The study aims to screen the possible mechanisms of compounds present in these herbal medicines which can offer possible explanations for their synergistic effects and rationalization of their combination in preparations.
Methods:
Network pharmacology was employed to determine pivotal proteins that are targeted by MC and LS compounds. Molecular docking was then done to evaluate the favorability of the binding of these compounds toward their target proteins.
Results:
Our results showed that TNF, HSP90AA1, MAPK3, ALDH2, GCK, AKR1B1, TTR and RBP4 are the possible pivotal targets of MC and LS compounds in T2DM.
Conclusion
Terpenoids from MC and decanoic acid from LS are the compounds which showed favorable binding towards pivotal protein targets in T2DM. By binding towards the different key proteins in T2DM, they may exhibit their synergistic effects. However, the results of this study are bound to the limitations of computational methods and experimental validation are needed to verify our findings.

The resin ethanol extract of Gegen Qinlian Decoction(GGQLD) has been found to significantly alleviate the intestinal toxicity caused by Irinotecan, but further research is needed to establish its overall quality and clinical medication standards. This study aimed to establish an HPLC characteristic fingerprint of the resin ethanol extract of GGQLD, predicted the targets and signaling pathways of its pharmacological effects based on network pharmacology, identified core compounds with pharmacological relevance, and analyzed potential quality markers(Q-markers) of the resin eluate of GGQLD for relieving Irinotecan-induced toxicity. By considering the uniqueness, measurability, and traceability of Q-markers based on the "five principles" of Q-markers and combining them with network pharmacology techniques, the overall efficacy of the resin ethanol extract of GGQLD can be characterized. Preliminary predictions suggested that the four components of puerarin, berberine, baicalin, and baicalein might serve as potential Q-markers for the resin etha-nol extract of GGQLD. This study provides a basis and references for the quality control and clinical mechanism of the resin ethanol extract of GGQLD.

To optimize the extraction process of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair by network pharmacology combined with analytic hierarchy process(AHP)-entropy weight method and multi-index orthogonal test. The potential active components and targets of Chuanxiong Rhizoma-Gastrodiae Rhizoma were screened by network pharmacology and molecular docking, and the process evaluation indexes were determined with reference to the Chinese Pharmacopoeia(2020 edition). The core components of Chuanxiong Rhizoma-Gastrodiae Rhizoma were determined as gastrodin, parishin B, parishin C, parishin E, ferulic acid, and 3-butylphthalide. With the extraction volume of each indicator and yield of dry extract as comprehensive evaluation indicators, the extraction conditions were optimized by the AHP-entropy weight method and orthogonal test as the ethanol volume of 50%, the solid-liquid ratio of 1∶8(g·mL~(-1)), extraction for three times, and 1.5 h each time. Through network pharmacology and molecular docking, the process evaluation index was determined, and the optimized process was stable and reproducible for the extraction of Chuanxiong Rhizoma-Gastrodiae Rhizoma herb pair, which could provide reference for in-depth research.

This study aimed to compare the efficacy of Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke with network Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library were searched from database inception to October 2022 for randomized controlled trial(RCT) on 11 Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke. The risk of bias plot was made by RevMan 5.3, and network Meta-analysis and efficacy ranking were performed by Stata 17. Ninety-two RCTs were included, involving 10 608 patients. According to the network Meta-analysis, in terms of the clinical total effective rate, surface under the cumulative ranking curve(SUCRA) as followed: Qilong Capsules+conventional western medicine>Zhishe Tongluo Capsules+conventional western medicine>Longshengzhi Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Tongsaimai Tablets+conventional western medicine>Naoan Capsules+conventional western medicine>Naoluotong Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine=Tongxinluo Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine. In terms of the improvement in National Institute of Health stroke scale(NIHSS) score, SUCRA as followed: Longshengzhi Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Naoluotong Capsules+conventional western medi-cine>Tongxinluo Capsules+conventional western medicine>Naoan Capsules+conventional western medicine>Qilong Capsules+conventional western medicine. In terms of safety, the overall adverse reactions/events of Qi-benefiting and blood-activating Chinese patent medicines + conventional western medicine were less than those of the control group. Since Qilong Capsules+conventional western medicine and Zhishe Tongluo Capsules+conventional western medicine were preferred to improve the clinical total effective rate. In the aspect of improving NIHSS score, Longshengzhi Capsules+conventional western medicine and Naomaitai Capsules+conventional western medicine were first options. Due to the lack of direct comparisons between drugs, the overall quality of RCT was not high, so more studies are needed to verify the strength of the evidence.

Journal of the Japanese Association of Rural Medicine 2007;56(1):34-38
Basal ganglia are an area where cerebral haemorrhage occures frequenthy. Recently our knowledge of the brain and its function increases rapidly, but this knowledge is not much used in rehabilitation yet. Parallel neural networks (Hikosaka, 1999) are a model of sequential procedures learning, and basal ganglia perform an important function in it. Using this model, we designed a rehabilitation approach and applied it to a patient with left putamen hemorrhage. In the early stage, we promoted passive movement of her paralysed arm and fingers in the spatial coordinates with her eyes opened. Afterwords, we guided her to motor leaning in the motor coordinates with somatic sensation with her eyes closed. We intended to integrate the spatial coordinates and motor coordinates, by which we encouraged her to move her arm and fingers with her eyes opened after her recognition of motion perception improved. Her motor paralysis of fingers in particular improved by rehabilitation, which lasted about 1.5 month. We recognized some improvement in her arm, but it was slightly insufficient than her fingers. We considered that a difference in the degree of improvement occurred because she could not confirm enough on her shoulder in the early stage.

Based on progress in home visits for rehabilitation and health guidance since 1979, the trend after the Nursing Care Insurance Law was enforced in 2000 was investigated. In home visits for rehabilitation, cooperation with many related organizations is required, and reorganization of the network built before the enforcement of the said Law is needed. The role of each home visiter for rehabilitation is being formed and cooperation with care managers is being strengthened. The tendency that the participation of the local government may decrease can't be denied. Connection with the hospital and the local government should be maintained, and a new community-based network needs to be built.

This study aimed to explore the mechanism of albiflorin in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking, and in vitro experiments. Network pharmacology was used to predict the potential targets and pathways of albiflorin against AD, and molecular docking technology was used to verify the binding affinity of albiflorin to key target proteins. Finally, the AD cell model was induced by Aβ_(25-35) in rat pheochromocytoma(PC12) cells and intervened by albiflorin to validate core targets and pathways. The results of network pharmacological analysis showed that albiflorin acted on key targets such as mitogen-activated protein kinase-1(MAPK1 or ERK2), albumin(ALB), epidermal growth factor receptor(EGFR), caspase-3(CASP3), and sodium-dependent serotonin transporter(SLC6A4), and signaling pathways such as MAPK, cAMP, and cGMP-PKG. The results of molecular docking showed that albiflorin had strong binding affinity to MAPK1(ERK2). In vitro experiments showed that compared with the blank group, the model group showed decreased cell viability, decreased expression level of B-cell lymphoma 2(Bcl-2), increased Bcl-2-associated X protein(Bax), and reduced phosphorylation level of extracellular signal-regulated kinase 1/2(ERK1/2) and the relative expression ratio of p-ERK1/2 to ERK1/2. Compared with the model group, the albiflorin group showed potentiated cell viability, up-regulated expression of Bcl-2, down-regulated Bax, and increased phosphorylation level of ERK1/2 and the relative expression ratio of p-ERK1/2 to ERK1/2. These results suggest that the mechanism of albiflorin against AD may be related to its activation of the MAPK/ERK signaling pathway and its inhibition of neuronal apoptosis.

Analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacology were employed to identify the potential quality markers(Q-markers) of Gei Herba. According to the new concept of Q-markers in traditional Chinese medicine(TCM), the AHP-EWM was applied to quantitatively identify the Q-markers of Gei Herba. The AHP was used for the weight analysis of primary indicators(factor layer), and the EWM for the analysis of literature and experimental data of secondary indicators(control layer). In addition, network pharmacology was employed to build the "component-target-disease-efficacy" network for Gei Herba, and the components showing strong associations with the Qi-replenishing, spleen-invigorating, blood-tonifying, Yin-nourishing, lung-moistening, and phlegm-resolving effects of Gei Herba were screened out. According to the results of AHP-EWM and network pharmacology, four components, i.e., ellagic acid, gallic acid, gemin G, and gemin C, were finally identified as potential Q-markers of Gei Herba. In this study, the AHP-EWM and network pharmacology were employed to screen the Q-markers of Gei Herba, which provided ideas for the quantitative evaluation and identification of Q-markers of TCM.
