[Objective]To summarize Professor WANG Xiaoming's academic experience in the treatment of children with tic disorder with the method of harmonizing the liver and spleen.[Methods]The essence of Professor WANG's method of treating children with tic disorder was analyzed from four aspects:theoretical source,theoretical basis,specific application and case study.[Results]The pathogenesis of children's tic disorder is mainly"liver effulgence and spleen deficiency",which is manifested as liver Yang hyperactivity,liver wind internal movement,spleen and stomach disharmony,even spleen and stomach weakness and muscle dystrophy.Therefore,in the treatment of this disease,the general idea is to harmonize the liver and spleen.Professor WANG stresses that the using this method to treat tic disorders,needs to flexibly sooth the liver,soften the liver,strengthen the spleen,relax the tendons,eliminate accumulation and stagnation,and other methods to adjust the liver and spleen,often choose Tianma Gouteng Drink,Erchen Decoction,Chaihu Shugan Powder,Sini Powder and other prescriptions for treatment.In the medical case of the article,Professor WANG distinguished the syndrome of liver effulgence and spleen deficiency,and treated it to harmonize the liver and spleen,the prescription was Tiaohe Zhidong Decoction,and the effect was remarkable.[Conclusion]Professor WANG's clinical treatment of children with tic disorder takes the coordination of liver and spleen as the starting point.According to the different clinical manifestations and syndrome groups of children,flexible prescription has a remarkable effect on relieving the tic symptoms of children,which is worth learning and promoting.

ObjectiveTo investigate the effect of high-definition transcranial direct current stimulation (HD-tDCS) combined with rehabilitation robot on upper limb and hand dysfunction in patients with subacute stroke. MethodsFrom December, 2019 to December, 2021, 50 inpatients with subacute stroke in Zhejiang Provincial People's Hospital were randomly divided into control group (n = 25) and experimental group (n = 25). Both groups received routine rehabilitation therapy, while the control group added sham HD-tDCS combined with rehabilitation robot, and the experimental group added HD-tDCS combined with rehabilitation robot, for four weeks. The upper limb and hand function was assessed with Action Research Arm Test (ARAT), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Motor Assessment Scale (MAS) before and after treatment. ResultsAfter treatment, the scores of ARAT, FMA-UE and MAS increased in the two groups (∣Z∣ > 3.320, t > 6.379, P < 0.01), while the scores of FMA-UE and MAS were higher in the experimental group than in the control group (Z = -2.379, t = 3.181, P < 0.05), as well as the scores of grasping and gross motor of ARAT (∣Z∣ > 2.033, P < 0.05). ConclusionThe combination of HD-tDCS and rehabilitation robot can be more effective on upper limb and hand function in patients with subacute stroke than rehabilitation robot alone.

Brain functional network changes over time along with the process of brain development, disease, and aging. However, most of the available measurements for evaluation of the difference (or similarity) between the individual brain functional networks are for charactering static networks, which do not work with the dynamic characteristics of the brain networks that typically involve a long-span and large-scale evolution over the time. The current study proposes an index for measuring the similarity of dynamic brain networks, named as dynamic network similarity (DNS). It measures the similarity by combining the "evolutional" and "structural" properties of the dynamic network. Four sets of simulated dynamic networks with different evolutional and structural properties (varying amplitude of changes, trend of changes, distribution of connectivity strength, range of connectivity strength) were generated to validate the performance of DNS. In addition, real world imaging datasets, acquired from 13 stroke patients who were treated by transcranial direct current stimulation (tDCS), were used to further validate the proposed method and compared with the traditional similarity measurements that were developed for static network similarity. The results showed that DNS was significantly correlated with the varying amplitude of changes, trend of changes, distribution of connectivity strength and range of connectivity strength of the dynamic networks. DNS was able to appropriately measure the significant similarity of the dynamics of network changes over the time for the patients before and after the tDCS treatments. However, the traditional methods failed, which showed significantly differences between the data before and after the tDCS treatments. The experiment results demonstrate that DNS may robustly measure the similarity of evolutional and structural properties of dynamic networks. The new method appears to be superior to the traditional methods in that the new one is capable of assessing the temporal similarity of dynamic functional imaging data.

Objective:To explore the relation of the radiochemical purity and in vivo imaging effect of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)- D-phe1-Tyr3-Thr8-octreotide (TATE) injection. Methods:High performance liquid chromatography (HPLC) and thin-layer chromatography (TLC) methods were established to determine 68Ga-DOTATATE, 68Ga 3+ , 68Ga in colloidal form and 68Ga-DOTA- D-Phe1-Tyr3-Thr8-dethreonine-octreotide (heptapeptide) and to study the influence of precursor purity on radiochemical purity of labelled products. The uptake of 68Ga-DOTATATE injection with different radiochemical purities was investigated in nude mice bearing AR42J cells by microPET imaging and the tumor target/non-target (T/NT) value was calculated. One-way analysis of variance and Pearson correlation analysis were used to analyze the data. Results:The contents of 68Ga 3+ and 68Ga in colloidal form were not related with precursor purity ( r values: 0.385, 0.497, P values: 0.306, 0.137), while the content of 68Ga-DOTA-heptapeptide was positively related with the purity of DOTA-heptapeptide ( r=0.957, P<0.001). The radiochemical purities of 68Ga-DOTATATE injection were (87.0±2.3)%, (86.8±0.8)% and (94.0±3.1)% when the DOTATATE purities were 90.9%, 91.6% and 99.2%, respectively. The results of microPET imaging showed that the tumor uptake was positively related with the radiochemical purity of 68Ga-DOTATATE injection ( r=0.828, P<0.001), and the T/NT values of 68Ga-DOTATATE injection with radiochemical purities of 95.7%, 85.8%, 84.5% and 79.9% were 21.25±8.84, 8.50±1.51, 11.38±1.65 and 6.01±0.99, respectively ( F=11.48, P=0.001). Conclusion:The radiochemical purity of 68Ga-DOTATATE injection is impacted by the purity of labelled precursor and manufacturing processes and is related with the imaging effect in vivo.

Objective:To explore the application effect of new whole-course closed sputum specimen collection technology in intensive care unit patients.Methods:From April 2020 to January 2022, the convenient sampling was used to select 442 ICU mechanical ventilation patients admitted to 6 hospitals in Jiaxing City as the research objects.

The control group adopted the traditional open sputum specimen collection technology, while the experimental group adopted the new whole-course closed sputum specimen collection technology. The heart rate, the incidence of hypooxygen saturation and the incidence of sputum spatter were compared between the two groups after sputum sample sampling. Results:The incidences of hypooxygen saturation and sputum spatter in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The new whole-course closed sputum specimen collection technology can effectively stabilize the oxygen saturation of ICU patients in the process of sputum specimen collection, reduce the incidence of sputum spatter and promote the safety of both patients and medical staff, which is worthy of clinical promotion and application.

Objective:To investigate the clinical characteristics and therapeutic methods of coronary artery aneurysm (CAA).Methods:The clinical data and coronary angiography of 32 patients confirmed by coronary angiography as coronary aneurysm in Shenzhen Hospital of Southern Medical University and Shenzhen People′s Hospital were collected. They were followed up, and the different therapeutic methods were analyzed.Results:Thirty-two cases (1.8%) of coronary artery aneurysms were found in 1 778 patients undergoing coronary angiography. The main sites of coronary ectasia were right coronary artery, anterior descending branch and circumflex branch, and the left main branch was rare. Among the patients with coronary artery aneurysms, there were 25 patients with coronary artery stenosis. All the 32 patients were given anticoagulant, antiplatelet, improvement of coronary spasm and statin therapy, among whom 2 patients were treated with stent implantation and 6 patients were treated with coronary artery bypass graft (CABG) and ligation of coronary aneurysm. During the follow-up (average 15 months) of 1 patient, acute myocardial infarction reoccurred, and coronary angiography indicated that the stenosed coronary segments after artery ectasia was occluded because of thromboembolism. In the remaining patients, there were no major cardiovascular events such as angina pectoris, acute myocardial infarction and sudden cardiac death.Conclusions:Coronary artery aneurysm is not a rare heart disease. Coronary thromboembolism, thrombosis and vasospasm are the main causes of angina pectoris and myocardial infarction. Anticoagulant, antiplatelet, antispasmodic drugs and suitable coronary artery bypass can significantly improve the clinical prognosis of patients with coronary artery aneurysm.

One major strategy to generate genetically modified mouse models is gene targeting in mouse embryonic stem (ES) cells, which is used to produce gene-targeted mice for wide applications in biomedicine. However, a major bottleneck in this approach is that the robustness of germline transmission of gene-targeted ES cells can be significantly reduced by their genetic and epigenetic instability after long-term culturing, which impairs the efficiency and robustness of mouse model generation. Recently, we have established a new type of pluripotent cells termed extended pluripotent stem (EPS) cells, which have superior developmental potency and robust germline competence compared to conventional mouse ES cells. In this study, we demonstrate that mouse EPS cells well maintain developmental potency and genetic stability after long-term passage. Based on gene targeting in mouse EPS cells, we established a new approach to directly and rapidly generate gene-targeted mouse models through tetraploid complementation, which could be accomplished in approximately 2 months. Importantly, using this approach, we successfully constructed mouse models in which the human interleukin 3 (IL3) or interleukin 6 (IL6) gene was knocked into its corresponding locus in the mouse genome. Our study demonstrates the feasibility of using mouse EPS cells to rapidly generate mouse models by gene targeting, which have great application potential in biomedical research.
