Objective To evaluate the length of hospital stay and the incidences of complications after omentoplasty with non-omentoplasty for the patients with esophageal cancer.Methods The databases including Pubmed,Embase,The Cochrane Library,Web of Science,CBM,CNKI,VIP and Wanfang data were searched for collecting randomized controlled trials on the omentoplasty.According to the inclusive and exclusive criteria,the datas were extracted.Two reviewers independently screened literatures and assessed the qualities of the included studies and extracted data.Meta-analysis was performed by using of RevMan 5.2 software.Results A total of 6 RCTs including 2 167 patients from 206 original articles were included in this analysis.In terms of the anastomotic leakage after esophagectomy and the hospital stays,the incidence of anastomotic leakage (OR =0.19,95％ CI:0.09 ～ 0.39,Z =4.55,P ＜ 0.000 01) and hospital stays (MD =-1.91,95％ CI:-2.26--1.57,Z =10.87,P ＜ 0.000 01) with omentoplasty was significantly lower than those of the non-omentoplasty,with significant differences.However,in terms of anastomotic stricture (OR =0.76,95％ CI:0.29-2.01,Z=0.55,P=0.58) and mortality rate (OR =0.72,95％ CI:0.24-2.21,Z=0.57,P=0.57),there wrer no significant differences.Conclusion Comparing with non-omentoplasty,the use of omentoplasty has beneficial effects for the postoperative complication such as anastomotic leakage and hospital stays,and does not increase the incidence of anastomotic stricture and mortality rate.

Objective:To observe the clinical efficacy of Ba-pulling and Qian-traction manipulation with neck suspension and movement for acute cervical radiculopathy. Methods: A total of 85 patients who met the inclusion criteria were randomized into an observation group and a control group by random numbers, with 43 cases in the observation group and 42 cases in the control group. The observation group was treated with Ba-pulling and Qian-traction manipulation with neck suspension and movement;while the control group was treated with Bashen-pulling and stretching manipulation in a supine position. The treatment was performed once a day, 10 times as a treatment course. The therapeutic efficacy was evaluated after 1 treatment course, and the changes in the scores of visual analog scale (VAS) and neck disability index (NDI) were observed. Results: The total effective rate was 97.7% in the observation group, and 83.3% in the control group, and the difference between the two groups was statistically significant (P＜0.05). After treatment, the VAS and NDI scores of both groups were significantly decreased (both P＜0.01), and the differences in the VAS and NDI scores between the two groups were statistically significant (both P＜0.01). Conclusion: Both Ba-pulling and Qian-traction manipulation with neck suspension and movement and Bashen-pulling and stretching manipulation in a supine position can relieve pain and improve cervical function in patients with acute cervical radiculopathy, and Ba-pulling and Qian-traction manipulation with neck suspension and movement can produce more significant efficacy than Bashen-pulling and stretching manipulation in a supine position.

Objective To develop a method of studying fiber projecting in the spinal cord duiring chicken embryo development.Methods At embryonic incubation 3 day (E3), pCAGGS-green fluorescent protein (GFP) plasmid was injected into the spinal cord using in vivo electroporation.Three days after transfection (E6), GFP-positive embryos were collected under a stereo fluorescence microscope .Subsequently , the spinal cord was separated from the embryos and cut from the roof plate as an open book .After fixed with 4%paraformaldehyde ( PFA) for one hour , the opened spinal cords were used for immunohistochemistry with N-cadherin antibody and with DAPI for nuclei .Finally, the nerve fiber projecting was photographed and analyzed under a fluorescence microscope . Results Based on the opened spinal cord and immunostaining in the cryosection , we observed that the nerve fibers projected across the midline of the floor plate and reached to the sulcus terminalis along the white matter of the contra side .The immunoreaction against N-cadherin indicated that overexpression of GFP has no significant effect on chicken embryonic development .Conclusion A new method to study fiber projecting in the developing chicken spinal cord is established successfully in this study .

Objectlve To investigate the value of basic and contrast-enhanced ultrasound in the diagnosis of superficial cervical lymph nodes.Methods Five hundred and forty-five cases of superficial cervical lymph nodes were sacned by basic ultrasound,in which 52 cases were also scaned by contrast-enhanced ultrasound.All cases were performed ultrasound-guided biopsy.Lymph nodes were divided into benign group and malignant group according to pathology reports.The differences of the two groups were analysed,and statistical analysis was performed.Results Two hundred and thirty cases were benign,315 cases were malignant.S/L(P＜0.01),RI(P＜0.01),vascular pattern(P＜0.01)and contrast enhancement pattern(P＜0.01)between benign and malignant group showed statistical significant differences,while no statistical difference in coefficient correlation of the time-intensity curve between the two groups was found.Conclusions A combination of basic and contrastenhanced ultrasound can significantly enhance the ability to identify malignant lymph nodes from benign lymph nodes.

Objective:To investigate the effect of MT01 on the differentiation of osteoblasts under infected condition through determining the expression level of collagen Ⅰ (Col Ⅰ )mRNA in MG63 cells treated with Porphyromonas gingivalis (Pg).Methods:The cultured MG63 cells were divided into blank control,MT01,Pg, and MT01+Pg groups.MT01 at a concentration of 1 mg·L-1 was added into the MG63 cells,and the cells were incubated for 3 h.The cells treated with PBS (1 mg·L-1 )were used as control group.Then Pg (MOI=100∶1) was added.Real-time PCR was used to detect the expression levels of ColⅠ mRNA in MG63 cells at 2,4,6,8, 12 and 24 h after incubation.Results:Compared with blank control group,the levles of ColⅠ mRNA in the MG63 cells in MT01 and MT01 + Pg groups had no significant changes at 2 and 4 h (P > 0.05);the Col Ⅰ mRNA expression levels in MT01 group at 8,12 and 24 h were increased (P < 0.05 or P < 0.01).Compared with Pg group,the expression levels of ColⅠ mRNA in MT01+ Pg at 2 and 4 h were decreased,but the expression levels of ColⅠ mRNA were increased at 6,8,12 and 24 h (P <0.05 or P <0.01).Conclusion:MT01 can up-regulate the expression level of Col Ⅰ mRNA in the infected MG63 cells; MT01 could promot the differentiation of osteoblasts under infected condition.

Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.

Objective To evaluate the clinical efficacy of dragon-tiger contending needling at Xi-cleft points plus electroacupuncture in treating postherpetic neuralgia (PHN).Method Seventy PHN patients were randomized into a treatment group of 36 cases and a control group of 34 cases. The treatment group was intervened by dragon-tiger contending needling at Xi-cleft points plus electroacupuncture, while the control group was treated with electroacupuncture alone. In the 4-week treatment, the Visual Analogue Scale (VAS) scores right before and after the 1st, 2nd, 6th, 9th and 12th treatment sessions were recorded, “the maximum pain intensity since the last treatment session” and “real-time analgesic effect” were observed, and the total therapeutic efficacy was also evaluated.Result The real-time analgesic effects right after the 1st, 2nd and 6th treatments in the treatment group were significantly better than those in the control group (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 2nd, 6th, 9th, and 12th treatment sessions were significantly different from the pain intensity before the intervention in the two groups (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 6th, 9th, and 12th treatment sessions were significantly different from those in the control group (P<0.05). The total effective rate and recovery plus markedly-effective rate were respectively 97.2% and 77.8% in the treatment group, versus 91.2% and 59.2% in the control group. There was a statistically significant difference in the recovery plus markedly-effective rate between the two groups (P<0.05).Conclusion Dragon-tiger contending needling at Xi-cleft points plus electro- acupuncture is an effective approach in treating PHN; it acts efficiently and can produce a satisfactory real-time analgesic effect.

OBJECTIVEThis aimed to investigate the effect of specific sequence oligodeoxynucleotide MT01 on the biological properties of osteoblasts invaded by Porphyromonas gingivalis (P. gingivalis ) by evaluating proliferation, cell cycle, and apoptosis.

METHODSMG63 osteoblasts were recovered and incubated with MT01, CpG ODN, metronidazole (MNZ), and gentamicin (GEN) for 3 h. P. gingivalis (the multiplicity of infection was 100:1) was added subsequently and cocultured for another 24 and 48 h. Cells with PBS comprised the blank group, whereas cells with P. gingivalis comprised the negative controls. Six experimental groups were established: PBS group, P. gingivalis group, MT01+P. gingivalis group, CpG ODN+ P. gingivalis group, MNZ+P. gingivalis group, and GEN+P. gingivalis group. The proliferative ability was measured by methyl thiazolyl tetrazolium assay, and the percentages of apoptosis and cell cycle were examined by flow cytometry.

RESULTSCompared with the blank group, proliferation increased significantly in the MT01+P. gingivalis group (P < 0.05). The ratio of cells was lower at the G₁ phase and higher at the S phase in the MT01+P. gingivalis group compared with the results in the P. gingivalis group (P < 0.05). Early cell apoptosis in the MT01+P. gingivalis group was significantly lower than that in the P. gingivalis group (P < 0.05).

CONCLUSIONMT01 can promote the proliferation, reduce the ratio of the G₁phase, increase the ratio of the S phase, and inhibit the early apoptosis of osteoblasts invaded by P. gingivalis.
