Objective To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis based on individual condition. Methods Twelve patients with intracranial venous sinus thrombosis were treated with endovascular management according to the severity and course of disease after they failed to respond to anticoagulant therapy. The clinical signs and symptoms,cerebrospinal fluid pressure and arteriovenous circulation time were observed and followed up (including MRV). Intravenous thrombolysis and mechanical thrombus maceration were carried out in all 12 patients,while intravenous thrombolysis, mechanical thrombus maceration in combination with intra-arterial thrombolysis were employed in 3. After the treatment, anticoagulant therapy was carried out for 6 months.The patients were followed up for 12 to 24 months. Results Of the twelve patients, clinical signs and symptoms included slight headache (2 cases), mild hemiplegia (1 case), ambiopia or blurred vision (3 cases). The cerebrospinal fluid pressure returned to under 26 cm H2O (1 cm H2O =0.098 kPa)following treatment from 28 to 38 cm H2O [ mean (32. 4 ±3.0) cm H2O] in preoperative measurement and the arteriovenous circulation time returned to below 10 s in all patients following treatment. Neither recurrence of thrombosis nor new symptoms of neurologic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation with the exception of a subcutaneous bleeding at the venopuncture site. Conclusion Endovascular treatment is effective and safe for patients with intracranial venous sinus thrombosis.

Objective To investigate the effect of bibliotherapy in soothing the postoperative pain in children and relieving the perioperative anxiety of children and their care givers. Methods Hospitalized children and their care givers from August 2007 to March 2009 were studied. 153 cases from August 2007 to May 2008 were assigned to the control group and the other 153 cases to the intervention group. Routine surgical nursing were applicated in the control group by introduction of perioperative nursing procedures.Bibliotherapy were applicated in the intervention group on the basis of the control group-using "bibliotherapy materials for hospitalized children" which was designed by ourselves and correspond with the theory of bibliotherapy to interfere in the 153 cases in the intervention group. The variance of preoperative anxiety of care givers and perceptions of postoperative pain of children between the two groups were compared with scales of mYPAS, STAI and FLACC and Wong- Baker Facial Scale. Results The scores of mYPAS in children of the intervention group and the control group was (35.875+4.441)and(46.796+8.606 )respectively and the variance was significant. The scores of STAI in care givers of the two groups was(38.125+4.371 )and (49.901 +7.420) respectively and revealed significant variance. The scores of Wong-Baker and FLACC in children of both groups 1 hour after operation were compared and revealed no statistical significance. The scores of Wong-Baker and FLACC in children at 6 hours and 24 hours postoperative were compared subjectively and objectively and revealed statistic significance. Conclusions Bibliotherapy can ameliorate the anxiety level of both children and their care givers, relieve the perception of postoperative pain in children and improve their comforts. Bibliotherapy thus conduces to the recovery of postoperative children.

AIM:To determine the effect of rhBMP2 on the migration of human breast cancer cells MCF-7. METHODS:MCF-7 was induced by rhBMP2 (30 ?g/L) for 24 h. Atomic force microscopy (AFM) was used to observe the changes in cell morphology. Cell migration and invasion abilities were assayed by scratch healing and transwell experiments. RESULTS:The formation of lamellipodia and cell polarity together with increased cell length were observed in the cells treated with rhBMP2,whereas lamellipodia of cells in control group were not obvious and the majority of cells tended to be rounder with shorter cell diameter. Compared to control group,scratch healing and transwell experiments showed that the migration and invasion capacity of rhBMP2-induced MCF-7 cells was markedly enhanced. CONCLUSION:rhBMP2 induces human breast cancer cell MCF-7 to present the phenotype of migration and enhances the invasion capacity.

Objective To evaluate the immune effects of bivalent inactivated rotavirus vaccine (IRV) and investigate the viability of development of bivalent IRV.Methods Firstly,bivalent IRV was prepared by mixing G1 IRV and G3 IRV with equal amount,G1 IRV and G3 IRV as monovalent control,PBS as negative control.Secondly,those vaccines were vaccinated to the mice by intramuscular injection.Then,to evaluate the immune effects of bivalent IRV,the levels of serum or fecal rotavirus specific IgG and IgA were assessed by ELISA,the levels of serum neutralized antibody were measured by microneutralization assay,the number of IFN-γ or IL-4 secreting cells were analyzed by ELISPOT assay.Results Compared to negative control group,bivalent IRV induced the higher levels of serum and fecal G1 and G3 rotavirus specific antibody.It was found that there were no significant differences for the levels of serum IgG and IgA,fecal IgG and IgA,serum neutralized antibody between induced by bivalent IRV and induced by G1 type monovalent vaccines ; but there were significantly increase for the levels of serum IgG (t =2.691,P＜0.05) and serum neutralized antibody (t =2.561,P＜0.05) between induced by bivalent IRV and induced by G3 monovalent vaccines,there were no significant differences for other antibodies between induced by bivalent IRV and induced by G3 monovalent vaccines.At the same time,compared to negative control group,bivalent IRV induced significantly increase in the number of IFN-γ or IL-4 secreting cells in spleen lymphocytes.It was found that there were no significant differences for the number of IFN-γ or IL-4 secreting cells stimulated by G1 rotavirus between bivalent IRV and G1 monovalent vaccines; but there were significantly increase for the number of IL-4 secreting cells (t =2.327,P＜0.05) stimulated by G3 rotavirus between bivalent IRV and G3 monovalent vaccines,there were no significant differences for the number of IFN-γ secreting cells stimulated by G3 rotavirus between bivalent IRV and G3 type monovalent vaccines.Conclusion The bivalent IRV can induce effective immune response,in which there were no inhibitory interference between the components of bivalent IRV,which provided the experimental basis for the development of bivalent IRV.

Although bone tissue has a certain ability of self-healing, bone transplantation is still needed for bone defects beyond the limit of self-healing. Calcium and phosphorus materials, such as hydroxyapatite and tricalcium phosphate, are currently common biological scaffold materials for bone repair, but these bioactive materials often lack osteoinductive activity, ability of promoting seed cell adhesion and angiogenesis. The traditional method to remedy these defects is to use growth regulators such as bone morphogenetic proteins to regulate the osteogenesis process on bioactive materials. However, these active factors often have the disadvantage of high cost and can not be used for a long time. In order to solve the above problems, a variety of small molecule active peptides were developed and played a good osteogenic effect. In this paper, a variety of common small molecule active peptides that induce osteogenesis were summarized and their research progress was reviewed.

Objective·To compare the effects and complications of carbon dioxide laser laryngectomy and open partial laryngectomy in the treatment of laryngeal carcinoma.Methods·Clinical data of 101 patients with stage Ⅰ-Ⅲ laryngeal squamous cell carcinoma admitted to Renji Hospital,Shanghai Jiao Tong University School of Medicine from January 2013 to January 2018 were selected and divided into open surgery group and minimally invasive group according to different surgical methods.The open surgery group received open partial laryngectomy(57 cases),and the minimally invasive group received carbon dioxide laser laryngectomy(44 cases).Follow-up visits were made by telephone and outpatient visits,and the operation time,postoperative laryngeal mucosa edema time,length of stay,5-year survival rate,complication rate and recurrence rate of the two groups were compared in the different clinical stages(stage Ⅰ,stage Ⅱ,and stage Ⅲ)and tumor locations(glottic type and non-glottic type).Results·The operation time,postoperative laryngeal mucosa edema time and length of stay of the minimally invasive group were shorter than those of the open surgery group(P＜0.05).Comparison of the 5-year survival rates of patients with the same clinical stage and glottic type between the two groups showed no statistically significant difference(both P＞0.05);while comparison of the 5-year survival rates of patients with non-glottic type between the two groups(62.5％in the open surgery group vs 0 in the minimally invasive group)showed a statistically significant difference(P＜0.05).In the minimally invasive group,there were 3 cases of complications,including 1 case of fever and 2 cases of lung infection;in the open surgery group,there were 14 cases of complications,including 5 cases of fever,7 cases of lung infection and 2 cases of pharyngeal fistula.The complication rate of patients in the minimally invasive group(6.82％,3/44)was lower than that in the open surgery group(24.60％,14/57),and the difference was statistically significant(P＜0.05);the complication rate of patients with stage Ⅱ and glottic type in the minimally invasive group was significantly lower than that in the open surgery group(P＜0.05).Comparing the recurrence rate of patients in the two groups(10.53％in the open surgery group vs 2.27％in the minimally invasive group),the difference was not statistically significant(P＞0.05).Conclusion·Compared with open partial laryngectomy,carbon dioxide laser laryngectomy has faster postoperative recovery and lower complication rate in the treatment of early and middle laryngeal malignant tumors,so it is worth promoting.

This paper was aimed to study the effect of Qing-Chang Wen-Zhong (QCWZ) decoction on interferon gamma induced protein 10 (IP10) in colon tissues of rats with ulcerative colitis (UC).The UC model was induced using 4.5％ DSS added to distilled water for 7 days.At the same time,low-,medium-and high-dose of QCWZ decoction and mesalazine was given by gavage route daily.Then,the rats were killed and the colon tissues were taken.Expression level of interleukin-1 alpha (IL-1α),IL-1β,IL-6,tumor necrosis factor alpha (TNF-α) and interferon gamma (INF-γ) in colon were detected by Elisa assay.The expression and distribution of IP10 protein were detected by immunohistochemistry (IHC).The results showed that compared with the normal group,inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ) and IP10 expression level in DSS-induced UC rats were significantly increased.After 7 days of intervention,inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ) and IP10 decreased significantly (p＜0.01,p＜0.05).It was concluded that QCWZ decoction may down-regulate the expression of IP 10 and inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ),and then inhibit intestinal inflammation and repair intestinal mucosal damage,so as to achieve the purpose of UC treatment.
