Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11＜0,95％ confidence interval (CI)-6.01 to-2.22,P＜0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42＜0,95％CI-5.19 to-1.66,P＜0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19＜0,95％CI-8.87 to 0.50,P＞0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08＜0,95％CI-3.09 to-1.06,P＜0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

The expression of silence of death domains (SODD) and its clinical significance and relationship with phospho-NF-kappaB-p65 proteins in bone marrow cells of childhood acute lymphoblastic leukaemia (ALL) were explored, and the expression of SODD and phospho-NF-kappaB-p65 in Jurkat cells treated with chemotherapeutic drugs was detected in order to find a new chemotherapeutic target. The expression of SODD and phospho-NF-kappaB-p65 proteins in bone marrow cells was detected by immunohistochemistry in 25 children with ALL. The apoptosis rate was measured by Annexin-V-Fluorescence/PI double-labeling flow cytometry and the expression of SODD and phospho-NF-kappaB-p65 proteins determined by Western blotting in the Jurkat cells. It was found that the expression of SODD and active P65 in ALL was significantly higher than that in normal control group (P<0.05). The expression of the SODD and phospho-NF-kappaB-p65 proteins in the high-risk (HR) group was significantly higher than that in the standard-risk (SR) group (P<0.05). The Pearson rank correlation analysis revealed that there was a positive correlation between SODD and phospho-NF-kappaB-p65 expression (P<0.01, r=0.69). VCR could effectively induce the apoptosis of Jurkat cells, and down-regulate the expression of SODD and phospho-NF-kappaB-p65 proteins in a time-dependent manner, but DNR could not down-regulate the expression of SODD effectively. It was concluded that SODD may be closely related to the clinical classification and prognosis of ALL in children. The expression of SODD and phospho-NF-kappaB-p65 had a definite synergistic relationship with the onset and development of ALL. VCR could down-regulate the expression of SODD and inhibit the NF-kappaB activation, which could recover the sensibility of apoptosis in leukemic cells.

BACKGROUND:Segmental bone defects resulting from osteoporotic fractures, trauma, congenital bone dysplasia and progressive bone disorder are very common, and bone tissue engineering provides a new approach to bone defect repair. Growth factors related to bone tissue engineering bone have been reported a lot and have achieved some results. How to mimick the natural timing of different growth factors with different bioactivities has become the current hotspot in bone repair. OBJECTIVE: To review the new developments in vascular endothelial growth factor and bone morphogenetic protein in bone tissue engineering. METHODS: The first author searched CNKI (1990/2015) and Medline database (1990/2015) for related articles using the key words of “osteogenic factors, angiogenic factors, tissue engineering bone, bone repair, vascularization, vascular endothelial growth factor, bone morphogenetic protein, sequential release, seed cels, cytoskeleton” in Chinese and English, respectively. Mechanism of action and research direction about vascular endothelial growth factor and bone morphogenetic protein were summarized. RESULTS AND CONCLUSION:Totaly 313 papers were searched initialy, and finaly 87 papers were enroled in result analysis. The results show that different growth factors play different roles in bone repair. Vascularization and osteogenesis are the most important processes in bone repair. The osteogenic factors play an important role in maintaining bone structure and bone formation. The angiogenic factors can provide oxygen and nutrients for tissue growth, differentiation and functionalization. The combination of osteogenic and angiogenic factors has a better osteogenic effect than osteogenic or angiogenic factors used alone. However, the most important problem is how to control the exogenous osteogenesis and the release dosage of angiogenic factors in bone repair.

Objective To study the clinical significance of the serum angiopoietin-2(Ang-2) in the diagnosis,recurrence,invasion and metastasis of gastric cancer.Methods The serum Ang-2 and carcino-embryonic antigen (CEA) levels in 158 patients with gastric cancer (gastric cancer group) and 30 normal controls(control group) were measured by enzyme linked immunosorbent assay(ELISA) technique respectively.The serum Ang-2 and CEA levels were also measured 2 weeks after operation in gastric cancer group and reexamined in the recurred gastric cancer patients in 2 years after operation (recurred and metastasis group).The correlation between the serum Ang-2 level and pathologic c haracterization of gastric cancer was evaluated.Results The serum Ang-2 and CEA levels in gastric cancer group [ (331.8 ±64.3),(42.6 ±37.3)μg/L] and recurred and metastasis group [(318.7 ±72.9),(40.5 ±36.7)μg/L] were significantly higher than those in control group [ (187.4 ± 32.7),(4.2 ± 3.1 )μ g/L] (P ＜ 0.01 ),and the serum Ang-2 level 2 weeks after operation [ (211.6 ± 75.1 ) μ g/L ] was significantly decreased to the control group (P ＞ 0.05 ),while the serum CEA level [ (33.4 ± 30.6) μ g/L ] was still significantly higher than the control group (P ＜ 0.01 ).The sensitivity of the serum Ang-2 for diagnosis of gastric cancer was markedly higher than that of the serum CEA (P ＜ 0.01 ).There was correlation between serum Ang-2 and degree of tumor differentiation,TNM pathological staging,lymphatic metastasis,invasion depth and tumor size (p ＜0.01 ),but there was no correlation between serum Ang-2 and tissue classification and location of gastric cancer (P＞ 0.05).Conclusion The serum Ang-2 level is suggested to be a valuable gastric cancer marker and conduce to the diagnosis of gastric cancer,the monitoring of recurrence after operation and evaluation of prognosis.

Objective To study the expression of cyclooxygenase-2(COX-2) and survivin in children with acute leukemia(AL) and its significance.Method The expression of COX-2 and survivin were determined by immunohistochemical SABC assay.Results The expression rate of COX-2 and survivin were 52.4%(22/42 cases)and 45.2%(19/42 cases)in AL,and the expression rate of COX-2 and survivin were 46.9%(15/32 cases)and 40.6%(13/32 cases)and in acute lymphonate leukemia(ALL),both of them were higher than those in control group(Pa0.05).The positive rate of COX-2 was 84%(16/19 cases)in 19 cases with survivin positive expression,and the negative rate of COX-2 was 85%(17/20 cases)in 20 cases with survivin negative expression,and there was positive correlation between COX-2 expression and survivin expression(r=0.579 P

This study was aimed to investigate the changes of silencer of death domains (SODD), survivin, caspase 3, caspase 8 and caspase 9 in the apoptotic process of human leukemia cells induced by chemotherapeutic drugs in order to explore the molecular mechanism of apoptotic modulatory genes and to search for the new target of chemotherapeutic drugs. After Jurkat cells were induced by chemotherapeutic drugs, the translocated phosphatidylserine was labeled with annexin V/PI, and the apoptosis incidence was measured by FCM; The expression changes of SODD, caspase 3, caspase 8 and caspase 9 were determined by Western blot; the changes of survivin mRNA and protein were determined by RT-PCR and immunohistochemistry SABC method respectively. The results indicated that high expressions of SODD and survivin could inhibit apoptotic signaling pathway; VCR down-regulated the function of SODD protein and effectively induced the apoptosis of Jurkat cells in a time-dependent manner and activates caspase 3 through the death receptor-mediated activation of caspase 8, in which caspase 9 and survivin were not degraded. It is concluded that SODD participates in the apoptotic process induced by VCR which induces the Jurkat cell apoptosis by downregulating expression of SODD protein and priming death receptor pathway. In the apoptotic process, the mitochondrion apoptotic pathway is not trigged.

OBJECTIVEMalignant middle cerebral artery (MCA) infarction is characterized by mortality rate of up to 80%. The aim of this study was to determine the value of decompressive craniectomy in patients presenting malignant MCA infarction compared with those receiving medical treatment alone.

METHODSPatients with malignant MCA infarction treated in our hospital between January 1996 and March 2004 were included in this retrospective analysis. The National Institute of Health Stroke Scale (NIHSS) was used to assess neurological status on admission and at one week after surgery. All patients were followed up for assessment of functional outcome by the Barthel index (BI) and modified Rankin Scale (RS) at 3 months after infarction.

RESULTSTen out of 24 patients underwent decompressive craniectomy. The mean interval between stroke onset and surgery was 62.10 h. The mortality was 10.0% compared with 64.2% in patients who received medical treatment alone (P<0.001). The mean NIHSS score before surgery was 26.0 and 15.4 after surgery (P<0.001). At follow up, patients who underwent surgery had significantly better outcome with mean BI of 53.3, RS of 3.3 as compared to only 16.0 and 4.60 in medically treated patients. Speech function also improved in patients with dominant hemispherical infarction.

CONCLUSIONDecompressive craniectomy in patients with malignant MCA infarction improves both survival rates and functional outcomes compared with medical treatment alone. A randomized controlled trial is required to substantiate those findings.

OBJECTIVETo investigate the etiology, pathology, and mechanism of pathogenesis of Moyamoya disease.

METHODSA total of 15 human autopsies were analyzed. In addition, in order to create an animal model of the disease, 21 Japanese rabbits were divided randomly into two groups and subjected to injections of horse serum either intravenously or locally in the area of the sympathetic ganglia. Pathological and immunohistochemical characteristics were observed.

RESULTSThe pathological features of the autopsies and the animal models both involved intima hyperplasia and stenosis or even occlusion of the lumen in the terminal ends of the internal carotid artery and the anterior and middle cerebral arteries. Disconnections or even breakages of the inner layer of the lumen were also observed, without an obvious inflammatory response. Hyperplasic smooth muscle cells of the medial membrane had extended inward through broken portions of the internal elastic lamina, with intima cell hyperplasia resulting in lumen stenosis. The hyperplastic vascular walls were positive for IgG and IgM.

CONCLUSIONSThe etiology of Moyamoya disease may involve allergic angiitis. A possible mechanism is that proximal portions of the circle of Willis first develop chronic stenosis or occlusion, leading to compensatory small vessel proliferation, which perforates into the cerebral parenchyma.
