Many clinical studies showed that the traditional Chinese medicine (TCM) syndromes in stroke have been dynamically changing since the onset of the disease. The changing of TCM syndromes can be attributed to multiple correlative factors such as age, sex, area distribution, underlying diseases, and constitutional factor. Data-driven methods involving multivariate statistical methods and descriptive approach have been used to analyze the regularity of dynamically changed TCM syndromes of stroke. However, expressing non-linear relationship between symptom or correlative factors and syndrome patterns by data-driven models is challenging. Model-driven methods involving artificial neural networks and Bayesian networks are new methods for studying the changes in TCM syndromes in patients with stroke. In this review, the authors summarized the studies of dynamically changed patterns of stroke syndromes based on data-driven methods and some clinical trials on TCM syndromes based on model-driven methods. Further studies are needed to improve the understanding of the dynamically changing regularity of TCM syndromes for stroke by using model-driven methods so as to develop appropriate and timely TCM treatments.

Objective To summarize the 18F-FDG PET/CT findings of LCH in children,and explore its value in the diagnosis of LCH.Methods PET/CT imaging and clinical data of 13 patients (6 males,7 females;average age (3.0±2.3) years) with LCH confirmed by histology before treatment from August 2011 to December 2015 in Xin Hua Hospital were retrospectively analyzed.Results All 13 patients have different degrees of bone destruction with increased metabolism,the common lesion sites were craniofacial bone,spine,limb long bones,ribs/chest/shoulder blade and pelvic bone.Lymph node lesions which manifested lymph node enlargement with increased metabolism were found in 10 cases,and the SUVmax was 4.0±1.3.Diffuse FDG uptake in spleen was found in 10 cases.There were 4 cases with liver lesions,3 with lung lesions,1 with high metabolic nodules in muscle,1 with orbital lesions and 1 with intraspinal high metabolic nodules.Conclusion 18F-FDG PET/CT could display the distribution and activity of LCH,and plays an important role in the diagnosis and systemic evaluation of LCH.

Objective: To investigate the cognitive impairment features in patients with amnestic mild cognitive impairment(aMCI) and vascular cognitive impairment-no dementia(VCI-ND).Methods:Sixteen normal elders,10 patients with aMCI and 12 patients with VCI-ND were recruited.The normal elders were selected from communities in Shanghai,while the aMCI and VCI-ND patients were selected from outpatient clinic.All participants ranged in age of 50～80 years,with education level of junior middle school or above,and they completed cranial CT or MRI and a series of neuropsychological tests.Results:In the three memory tests,aMCI group performed worst.The scores of both aMCI and VCI-ND groups were lower than that of the normal elders.For example,the delayed recall scores of the Rey-Osterrich complex figure test in the three groups were(18.8?9.5)(normal),(5.6?5.6)(aMCI) and(9.6?7.0)(VCI-ND)(P

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.

Objective To investigate the usefulness of 99Tcm-MDP whole body bone scintigraphy (WBBS) in patients with synovitis,acne,pustulosis,hyperostosis,osteitis (SAPHO) syndrome.Methods 99Tcm- MDP WBBS was performed in 25 patients (6 males,19 females,mean age =(55.1 ±9.8) years)with SAPHO syndrome.Bone lesions were classified into five categories:anterior chest wall,spine,mandible,sacroiliac joint,and limbs.The typical scintigraphic manifestations of SAPHO syndrome were summarized and compared to other radiological imaging data.Results Among 25 patients,32％ of cases (8/25)were associated with skin lesion; 48％ ( 12/25 ) were pathologically diagnosed with chronic nonspecific bone inflammation by bone biopsy.On 99Tcm-MDP WBBS,abnormal metabolic foci at anterior chest wall were found in all cases,most of which located in the sternocostoclavicular region (96％,24/25 ),including sternoclavicular joints (60％,15/25),first costosternal junctions (48％,12/25),and manubriosternal junctions (44％,11/25 ).Only 20％ of the patients (5/25) demonstrated the typical scintigraphic characteristic:“bull's head” sign.The second most frequent part was spine (44％,11/25).Appendicular skeleton was affected in 16％ (4/25) patients.WBBS also demonstrated additional skeletal lesions in 68％ (17/25 ) of the patients,mainly in first costosternal junctions (7 patients),sternoclavicular joints (6 patients),manubriosternal junctions (5 patients) and spine (4 patients).Conclusions Abnormal metabolic foci in sternocostoclavicular region and other imaging manifestations on 99Tcm- MDP WBBS can be used to diagnose,differentiate,and localize the insidious lesion and evaluate the lesion activity in patients with SAPHO syndrome.

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.

METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.

RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).

CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.
