PURPOSE: To evaluate the prognosis of nasopharyngeal carcinoma (NPC) patients who developed bone-only metastasis after primary treatment and the stratification of these patients into different risk groups based on independent prognostic factors. MATERIALS AND METHODS: Eighty NPC patients who developed bone-only metastasis after definitive radiotherapy from October 2005 to December 2010 were enrolled. All these patients received palliative treatment for bone metastasis, including chemotherapy and/or radiotherapy. Clinical features, treatment modality, and laboratory parameters were examined with univariate and multivariate analyses. RESULTS: The median follow-up time was 15.5 months (range, 2-67 months) for the whole cohort. The median overall metastatic survival (OMS) time and the 2-year estimate OMS rate were 26.5 months and 52%, respectively. Multivariate analysis indicated that patients with short metastases-free interval, multiple bone metastases sites, high serum lactic dehydrogenase levels, and treated with radiotherapy or chemotherapy alone had significantly worse outcomes. Patients were stratified into three different risk groups based on the number of adverse factors present. The OMS curves of the three groups were all significantly different (p<0.001). CONCLUSION: Severl prognostic factors were found to be associated with worse outcomes. According to the number of adverse factors present, bone-only metastasis patients can be stratified into three risk groups with significantly different prognoses. Such grouping may help in improving the design of clinical trials and in guiding individualized treatment for NPC patients with bone-only metastasis.

Objective To investigate the clinical features, treatment strategies and outcomes of patients with Moyamoya disease and lenticulostriate artery (LSA) aneurysm rupture. Methods Patients with moyamoya disease and LSA aneurysm rupture admitted to Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medicine School from October 2012 to March 2015 were analyzed retrospectively. They were followed up for 1 year. The modified Rankin Scale (mRS) was used to evaluate the outcomes, and 0-2 was defined as good outcome. The demographic characteristics, image anatomical features, treatment schemes, and outcomes of the patients were summarized. The Pubmed database was used to retrieve other similar studies, which combined with this group of cases for analysis. Results A total of 10 patients were enrolled, 2 males and 8 females, aged 29-72 years, with an average of 43. 6 years. All cases were intracranial hemorrhage, including 3 cases of cerebral hemorrhage, 6 cases of ventricular hemorrhage, and 1 case of subarachnoid hemorrhage. At the time of admission, 7 patients had disturbance of consciousness, and 3 patients underwent emergency extraventricular drainage. Among them, 5 patients received endovascular embolization, 4 had good outcome, 1 had mild neurological deficit (mRS score 3); 2 received surgical treatment, all had good outcome; 3 received conservative treatment, all had re-bleeding, 2 died, and 1 had severe disability (mRS score 4). Fourteen eligible articles were included, and a total of 18 patients were included in the analysis: surgical treatment in 7 cases, endovascular treatment in 6 cases, and conservative treatment in 5 cases (self-healing in 1 case). According to the data of this group of patients and literature reports, the good outcome rate of the patients with early interventional embolization or craniotomy clipping treatment was significantly higher than that of conservative treatment (70. 6％vs. 22. 2％; P = 0. 038). Conclusion There is a certain risk of conservative treatment of Moyamoya disease complicated with LSA aneurysm rupture and requires active treatment. Interventional embolization of the parent artery or surgically clipping of aneurysm can effectively improve the clinical outcome of such patients. Interventional embolization of the parent artery and aneurysm can be selected simultaneously if the condition of the parent artery is allowed. Surgery can be selected when the condition of parent artery is poor and the aneurysm is located in the superficial part.

OBJECTIVE： To conduct virtual screening for active component， target and pathway of TCM Yiqi ziyin decoction in the treatment of type 2 diabetes mellitus， and to elucidate the pharmacodynamic mechanism of this decoction in the treatment of type 2 diabetes mellitus at molecular level so as to provide theoretical basis for its popularization， application and rational organization. METHODS： Chemical compounds isolated from 10 ingredients of Yiqi ziyin decoction were retrieved from Handbook of Chemical Constituents of Original TCM Plants. Drug/drug-like molecules for the treatment of type 2 diabetes mellitus were retrieved from DrugBank database. Three-dimensional molecular structures of each component were downloaded from PubChem Compound database. The structure was optimized by using Cerius2 4.10 software， and the small molecular data set of Yiqi ziyin decoction was established. Using “type 2 diabetes mellitus” as keywords， target protein of type 2 diabetes mellitus were retrieved and screened from target protein databases， and their three-dimensional structures were downloaded from protein database. The selected compound molecules （ligands） were docked with target proteins （receptors）， and small molecules with high activity （sorted according to the values of Degree and Betweenness） and target proteins with high correlation were found. The interaction mechanism between ligand and receptor was discussed by taking the fine docking of selected small molecules with target protein （N-trans-caffeoyl tyrosine molecule and glycogen synthase kinase-3β） as an example. RESULTS： There were 732 kinds of chemical components and 127 drug/drug-like molecules； 30 target proteins of type 2 diabetes mellitus were screened. According to the values of Degree and Betweenness， 8 molecules with high activity （such as N-trans-caffeoyl tyrosine， hyperin and so on） and 10 target proteins with high correlation （such as carbonic anhydrase1， glycogen synthetase kinase-3β and so on） were screened out. The interaction between N-trans-caffeoyl tyrosine and glycogen synthase kinase-3β could form hydrogen bonds and π alkylation， thus affecting the structural stability and activity of the latter and reducing blood glucose. CONCLUSIONS： In this study， it found there existed not only one molecule compound interacting with multiple targets， but also different molecule compound  interacting with the same target on Yiqi Ziyin decoction for the treatment of type 2 diabetes mellitus by virtual screening， it revealed the characteristics of multi-component and multi-target synergism of TCM prescriptions at the molecular level， providing reference for screening lead compounds and structural modification of new drug for diabetes mellitus.

Objective:To verify the clinical efficacy and safety of Qufeng Tongxuan method in treating low- and moderate-volume intracerebral hemorrhage at acute stage.Methods:A prospective, multicenter, randomized, double-blind, placebo-controlled study was performed; patients with low- and moderate-volume intracerebral hemorrhage at the basal ganglia and/or thalamus accepted treatment in 16 hospitals from September 2019 to April 2022 were enrolled. These patients were divided into experimental and control groups with a block randomized method by SAS software. Patients in control group were given conventional western medicine treatment; those in experimental group accepted Qufeng Tongxuan method (sequential therapy of Shexiang Huayu Xingnao granules and Zhilong Huoxue Tongyu granules) besides conventional western medicine treatment. NIHSS was used to assess neurological function before treatment and on 7 th, 14 th, 30 th, and 90 th d of treatment. Prognoses of these patients were assessed by modified Rankin scale (mRS) before treatment and on 180 th d of treatment. Brain CT was performed before treatment and on 7 th and 14 th d of treatment to calculate the hematoma volume. Before treatment and on 14 th d of treatment, changes of coagulation function, liver and kidney functions of the 2 groups were compared. Adverse reactions during treatment in the 2 groups were recorded. Results:No significant differences in NIHSS scores were noted between the 2 groups before treatment, on 7 th, 14 th, and 30 th d of treatment ( P>0.05); NIHSS scores in experimental group on 90 th d of treatment were signficantly lower than those in control group ( P<0.05); NIHSS scores in experimental group decreased gradually before treatment and on 7 th, 14 th, 30 th and 90 th d of treatment, with statistical significances ( P<0.05). No significant differences in mRS scores were noted between the 2 groups before treatment ( P>0.05); mRS scores in experimental group on 180 th d of treatment were signfciantly lower than those in control group ( P<0.05). No significant difference in hematoma volume was noted between the 2 groups before treatment and on 7 th and 14 th d of treatment ( P>0.05); both groups had gradually decreased hematoma volumes before treatment and on 7 th and 14 th d of treatment, respectively, with significant differences ( P<0.05); the volume difference of hematoma between 14 th d of treatment and before treatment in experimental group (6.42[4.10, 11.73]) was significantly higher than that in control group (4.00[1.25, 10.58], P<0.05). No significant differences in liver and kidney function indexes or coagulation function indexes were noted between the 2 groups before treatment and on 14 th d of treatment ( P>0.05). Adverse reaction incidence was 9.52% ( n=12) in experimental group and 10.34% ( n=12) in control group, without statistical difference ( P>0.05). Conclusion:Under premise of conventional western medicine treatment, Qufeng Tongxuan method can promote hematoma absorption and improve neurological deficit symptoms in low- and moderate-volume intracerebral hemorrhage at acute stage, without obvious adverse reactions.
