Objective To investigate the diagnostic value of MRI in reversible splenial lesion syndrome (RESLES) in children.Methods The clinical and MRI imaging data of 14 cases of RESLES in children were retrospectively reviewed.There were 4 males and 10 females,aging 11 to 35 months.Average age was (20±3) months.MRI studies were conducted in all the cases.Two experienced doctors analyzed independently the images and reached consensus.Results Fourteen cases showed the single abnormal signal in the splenial of corpus callosum on the initial cerebral MRI.Lesions in 10 of 14 cases appeared as isointensity on T1WI,hypo-intensity in 4 cases.Lesions in 14 cases were appeared as hyper-intensity on T2WI,hyper-/slightly hyper-intensity on FLAIR T2WI.The lesions were round,oval or irregular,with fuzzy boundary.DWI showed round or oval high signal with clear boundary.No edema around the lesion and no occupying effect were detected.After treatment,8 of 14 cases were reviewed after 7-14 d,and the abnormal signal in the corpus callosum disappeared in 5 cases,while the range was significantly reduced in 3 cases.MRI were reexamined after 1-2 months in 5 cases,and the lesions disappeared in the corpus callosum.One case didn't have MRI examination again after treatment and the clinical symptoms disappeared.Conclusions The clinical manifestations of RESLES in children are lack of specificity.And the cerebral MRI imaging is characterized by the reversible solitary lesion of the splenium,which can provide a reliable basis for clinical diagnosis and prognosis.

Objective To observe the clinical effect on sleep improvement about acupoint application in treating the chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.Methods A total of 68 patients with chronic insomnia with Liver-stagnation and Spleen-deficiency Syndrome were randomly and blindly divided into treatment group and control group by registration order. In the treatment process, 1 was eliminated and 33 were completed in the treatment group, 2 were eliminated and 32 were completed in the control group. The treatment group underwentAn Mian Tietherapy half an hour before bed and the control group underwent placebo therapy in the same way of treatment group. Two groups were treated for 40 days and followed-up visit six months. The change of Pittsburgh Sleep Quality (PSQI), Index Insomnia Severity Index (ISI) and TCM Syndromes Scale were detected.Results The clinical total effective rate of treatment group was 72.7% and the control group was 9.4%, and the difference was statistically significant (χ2=46.977,P<0.01). The PSQI scores after treatment (7.55 ± 1.52vs. 13.90 ± 2.44,t=148.165), and follow up 1 month (8.97 ± 2.51vs. 13.17 ± 2.79,t=37.926) in the treatment group were significantly lower than those in the control group (P<0.01). The ISI scores after treatment (7.03 ± 3.37vs. 20.89 ± 4.40,t=73.75), and follow up 1 month (9.81 ± 3.16vs. 19.41 ± 3.66,t=40.79) in the observation group were significantly lower than those in the control group (P<0.01). The TCM Syndromes Scale scores after treatment (2.05 ± 1.09vs. 6.98 ± 1.23,t=17.116), and follow up 1 month (4.06 ± 1.59vs. 6.83 ± 0.91,t=68.055) and follow up 6 month (5.12 ± 1.84vs. 7.19 ± 1.07,t=27.716) in the observation group were significantly lower than those in the control group (P<0.01).Conclusions Acupoint application could obviously change the sleep quality and Chinese medicine symptom in chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Objective:To explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.

Objective:To study the effects of electron beam irradiation and 60Co irradiation on the composition changes of four alkaloids in Sophorae Flavescentis Radix, intermediate extracts of Sophorae Flavescentis Radix and Lixieling Tablets. Methods:Sophorae Flavescentis Radix, intermediate extracts of Sophorae Flavescentis Radix and Lixieling Tablets were irradiated at different doses of 0, 1.5, 3, 5, 7, 10, 20, 30, 40 kGy by electron beam irradiation and 60Co irradiation. The contents of oxymatrine, oxysophocarpine, matrine and sophocarpine were determined by HPLC, and the changes of the components before and after irradiation were compared. Results:Oxymatrine, oxysophocarpine, matrine and sophocarpine were among 0.046 9-0.937 4 μg, 0.020 5-0.410 4 μg, 0.098 9-1.977 9 μg, 0.048 7-0.973 1 μg, respectively. The linear relationship was good. The average recovery rates were 98.1%, 100.1%, 100.5%, 96.6%, respectively, and the RSDs were 1.69%, 2.03%, 3.14% and 1.10%, respectively. Electron beam irradiation and 60Co irradiation had no statistical significance on the changes of oxymatrine, oxysophocarpine, matrine and sophocarpine in Sophora flavescens, but had statistical significance in the contents of intermediate extracts of Sophorae Flavescentis Radix and Lixieling Tablets. Conclusion:The established method for the determination of matrine is accurate, reproducible, simple and practical, and can be used for the quality control of Lixieling Tablets. Irradiation has no significant effect on the content of Sophorae Flavescentis Radix, while high dose irradiation has significant effect on the intermediates and finished products of Sophorae Flavescentis Radix, which can provide a basis for quality control and sterilization irradiation of enterprises.

OBJECTIVE：To optimi ze the optimal composition proportion of 4 ingredients （Panax ginseng ，Astragalus membranaceus，Polygonatum sibiricum ，Lycium chinensis ）in Compound ginseng immune-enhancing formula （CGIF），and to study immune activity and acute toxicity of the extracts with the optimal ratio. METHODS ：The cell activity test was used to screen the crude drug concentration range of 4 ingredients. After treated with different crude drug concentrations of each medicinal material，using the contents of NO ，IL-6 and TNF-α as indexes，uniform design was used to determine the optimal ratio of each ingredient in CGIF. Totally 240 mice were taken and randomly divided into 4 batches，with 60 mice in each batch. Each batch of mice was randomly divided into blank group （normal saline ），model group （normal saline ），positive drug group [levamisole ，4 mg/（kg·d）]，and optimal proportion extract of CGIF low-dose ，medium-dose and high-dose groups [ 0.952 8，1.905 6，3.811 2 g/（kg·d）]，with 10 mice in each group ；they were given medicine intragastrically ，qd，for consecutive 30 d. Except for blank group，mice in the other groups were intraperitoneally injected with cyclophosphamide [ 40 mg/（kg·d）] on the 24th day after first administration，qd，for consecutive 3 d to induce immunocompromised model. The immune activity of the optimal proportion extract was evaluated by determining visceral coefficients ，spleen lymphocyte transformation capacity ，serum contents of hemolysin，IL-2，IgM，IgG and IgA ，phagocytosis function of peritoneal macrophages. Another 20 mice were collected and given the optimal proportion extract 20 mL/kg intragastrically ，twice；acute toxicity of the formula was investigated with oral maximum tolerated dose （MTD）. RESULTS ：The optimal ratio of CGIF was that crude drug mass ratio of P. ginseng ， membranaceus，P. sibiricum ，L. chinensis was 1 ∶ 2 ∶ 2 ∶ 4. The immunological activity experiment showed that theoptimal proportion extract can significantly improve visceral indexes of mice ， spleen lymphocyte proliferation ability serum contents of hemolysin ，IL-2，IgM，IgG and IgA as well as macrophage phagocy tosis ability （P＜0.05 or P＜ 0.01）. The acute toxicity test indicated that oral MTD was over 15 g/kg，which was non-toxic. CONCLUSIONS ：The optimal proportion extract of CGIF can significantly enhance the immune function of mice and are non-toxic.
