Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

Objective To evaluate accuracy of cefoxitin disk testing for detecting oxacillin resistance coagulase-negative staphylococci (MRCNS). Methods 139 clinical coagulase-negative staphylococci (CNS) were detected with ID32 STAPH. Cefoxitin disk and oxacillin disk testing were used to detect MRCNS. PBP2a was tested by latex agglutination us a reference method. Results 139 CNS isolates were identified to 8 species: Staphylococcus haemolyticus , S. epidermidis , S. hominis , S. xylosus , S. saprophyticus , S. auricularis , S. simulans and S. warneri. The sensitivity and specificity for cefoxtin disk and oxacillin disk testing were 99.0% vs. 86.0% and 91.7% vs. 74.4%, respectively. One S. epidermidis strain was identified to affect the sensitivity of cefoxitin disk testing. S. xylosus, S. warned, and S. saprophyticus were major species related to the decrease of specificity of cefoxitin disk testing. S. haemolyticus, S. hominis, S. simulans and S. auricularis were major species related to the decrease of sensitivity of oxacillin disk testing. And the decrease of specificity of oxacillin disk testing were mainly related to S. hominis , S. simulans , S. xylosus , S. auricularis , S. saprophyticus and S. warneri. Conclusions The accuracy of MRCNS detection by cefoxitin disk testing is varied due to different CNS species. So it is necessary to test PBP2a or mecA gene according to CNS species, especially for S. xylosus, S. warned and S. saprophyticus.

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

Background Corneal transplantation is the most reliable and effective means to treat the corneal blindness in the clinical,immune rejection is a major cause of corneal graft failure after the keratoplasty.Objective This study aimed to investigate the role of Tim-1 in the immune reaction following corneal transplantation in rats.Methods Forty clean female Wistar rats were randomized into normal control group,autologous corneal transplantation group and allogeneic corneal transplantation group.Penetrating corneal transplantation was performed with the Wistar rat donors and Wistar rat receipts in the autologous corneal transplantation group,while with the SD rat donors and Wistar rat receipts in the allogeneic corneal transplantation group.The corneal graft diameter was 3.5 mm and the plant bed diameter was 3.0 mm.The inflammatory response of the grafts was examined under the slit lamp microscope 7 days and 14 days after operation and scored based on the criteria of Larkin.Rejection index (RI),mean survival time and survival rate were calculated.The histopathological examination was performed 7 days and 14 days after surgery to evaluate the inflammatory manifestation,and the expressions of Tim-1 protein and mRNA were assayed by immnunochemistry and real-time fluorescence quantitative PCR (RT-qPCR)in the time points mentioned above.Results Mild edema of the grafts were found 7 days after operation in both the autologous corneal transplantation group and the allogeneic corneal transplantation group.In postoperative 14 days,the grafts were clear in the autologous corneal transplantation group,but the thickening,neovacularization and cloudy of the grafts were exhibited in the allogeneic corneal transplantation group.The survival rate of the grafts was 100％ in the autologous corneal transplantation group and that of the allogeneic corneal transplantation group was 0 with the survival time of (9.8±1.2) days.Histopathological examination revealed the stromal infiltration of inflammatory cells in both the autologous and allogeneic corneal transplantation groups in the seventh day,however,the inflammatory cells were obvious decreased in the autologous group but increased in the allogeneic corneal transplantation group in the fourteenth day.Immunochemistry showed a gradually declined positive cells for Tim-1 protein in the autologous corneal transplantation group,but the positive cells were exactly elevated in the allogeneic corneal transplantation group from 7 days through 14 days after operation;While only few positive cells were seen in the normal control group.The expression levels of Tim-1 mRNA in the grafts were 1.24 ± 0.03,5.85 ± 0.08 and 6.54 ± 0.20 in the normal control group,autologous corneal transplantation group and that of the allogeneic corneal transplantation group,respectively,in the seventh day,and in the fourteen day after operation,the expression level declined to 1.54 ±0.10 in the autologous corneal transplantation group and elevated to 8.62±0.24 in the allogeneic corneal transplantation group,showing significant differences among the different groups and various time points (Fgroup =3 277.590,P =0.000 ; Ftime =136.000,P =0.000).Conclusions Tim-1 may play an important role not only in the inflammatory response but also in the rejection reaction of the corneal transplantation.

OBJECTIVETo study the effect of tea polyphenols (TP) on the apoptosis of germ cells in rats with experimental varicocele.

METHODSThirty-two adolescent male Wistar rats were randomly and equally divided into groups A (sham-operation), B (high-dose TP), C (low-dose TP), and D (experimental left varicocele). Experimental varicocele was induced by partial ligation of the left renal vein in the latter three groups of rats. The animals in groups A and D were fed with normal saline, while those in B and C with TP at 40 and 10 mg per kg per d, respectively, all for 4 weeks. Then, all the rats were sacrificed and the left testes harvested for determination of the expression of HIF-1, Bcl-2, Bax, CytC, and caspase-3 by immunohistochemistry and measurement of the apoptosis index (AI) of spermatogenic cells.

RESULTSThe expression of Bcl-2 was higher in groups B and C than in D but lower than in A (P < 0.05), and lower in C than in B (P < 0.05). However, the expressions of HIF-1, Bax, CytC, and caspase-3 were lower in groups B and C than in D but higher than in A (P < 0.05), and higher in C than in B (P < 0.05). The AI of spermatogenic cells was the lowest in group A, higher in D than in the other groups but lower in B than in C (P < 0.05).

CONCLUSIONTP can reduce the apoptosis of spermatogenic cells in a dose-dependent manner in varicocele rats.

OBJECTIVETo investigate the antitumor effect of a benzoquinone ansamycin antibiotic, geldanamycin (GA), against HER2 /neu tyrosine kinase-overexpressing human breast cancer cell line SKBr3.

METHODSTo evaluate the antitumor activity of GA, the degradation of HER2 /neu tyrosine kinase in GA-treated SKBr3 cells was analyzed by Western blotting, their proliferation assessed using MTT assay, and the cell cycle distribution identified by flow cytometry. RT-PCR and Real-time PCR were employed to detect cyclin D1 mRNA expression and cell culture inserts model was used to evaluate the motility of the cells.

RESULTSGA induced a dose- and time-dependent degradation of HER2 /neu tyrosine kinase and cell proliferation inhibition. GA treatment obviously decreased the survival rates of the cancer cells, leading also to a dose-dependent G(1) arrest. The antitumor effects of GA proved to be relevant with declined transcription of cyclin D1. The GA-treated cells also exhibited reduced motility.

CONCLUSIONGA can efficiently destabilize HER2 /neu tyrosine kinase and inhibit the proliferation and motility of human breast cancer cell line SKBr3 overexpressing HER2 /neu tyrosine kinase.

OBJECTIVETo investigate the effect of extract of Ginkgo Biloba(EGB) on nerve growth factor(NGF) and Neurotrophin-3(NT-3) expression of hippocampus neurons in streptozotocin-induced type I diabetic rats.

METHODSThirty male SD rats were divided into three groups (n = 10): the control group, diabetic group and EGB-treated group. Strepozotocin were injected intraperitoneally in the later two groups to induce diabetes. EGB-treated group was injected intraperitoneally with EGB, and the same volume of normal saline was injected to the other groups. Concentration of blood glucose and body weight and behaviour were dynamicly monitored. At the end of the 12th week, morphological changes of the hippocampus neurons were observed under microscopy by HE stain. The expression of NGF and NT-3 were assayed by Western blot and RT-PCR respectively.

RESULTSCompared with diabetic group, the behaviour and body weight (P < 0.05) and the concentration of blood glucose (P < 0.05) were significantly improved and the escape latency of Morris water maze test (P < 0.05) was significantly shortened, while the platform searching score was significantly increased (P < 0.01) in EGB treated group; The pathological changes of hippocampus neurons were significantly attenuate by EGB treated; The expression of NGF and NT-3 in hippocampus neurons were significantly increased which assayed by Western blotting and RT-PCR respectively (P < 0.05) in EGB treated group.

CONCLUSIONEGB may improve the learning and memory ability of diabetic rats the mechanism may be attributed to its improvement of the expression of NGF and NT-3 and reducing apoptosis in hippocampus neurons.
