RESUMEN
Objective@#To compare the clinical effects between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) assisted by Microendoscopic discectomy (MED) and Quadrant for the treatment of degenerative lumbar spinal stenosis (DLSS).@*Methods@#All of 59 patients suffered from DLSS treated surgically from May 2015 to October 2017 were reviewed. According to the surgery method, all cases were divided into MED group (27 cases) and Quadrant channel group (32 cases). All patients were followed up for an average of 18.5 months (11-29 months). Comparison was made on the operative time, intraoperative blood loss, postoperative drainage, postoperative time in bed, postoperative creatine kinase (CK), fusion rate and the degree of muscle fibrosis shown in MRI, as well as visual analogue scale (VAS)score and Oswestry dysfunction index (ODI) score in two groups.@*Results@#The duration of operation in MED group was significantly longer than that in Quadrant group (161.7±22.4 min vs. 145.6±19.4 min, t=4.541, P<0. 01), but less intraoperative blood loss (138.1±26.9 ml vs. 155.6±21.5 ml, t=-2.724, P< 0. 01) and shorter time in bed after surgery (2.3±0.7 d vs. 3.5±1.1 d, t=-4.564, P<0.01). Compared with Quadrant group, CK levels were risen slightly on the first and third postoperative day (P<0.01). CK on the fifth postoperative day in both groups returned to normal. VAS score of lower back pain in MED group was lower than that in Quadrant group on the third day and twelfth month after operation (P<0.05). After 3 months, there was no significant difference in VAS score and ODI between the two groups (P>0.05). ODI was lower in MED group than that in Quadrant group after 6 months and 12 months.The fusion rate was88.9%(24/27) in MED group and 93.8%(30/32) in Quadrant channel group. There was no statistical difference in fusion rate of two groups. 10 patients in MED group and 12 patients in Quadrant group underwent MRI examination of lumbar spine one year after operation. The ratio of postoperative and preoperative atrophy of multiplex muscle area was measured. Muscle atrophy of lower back muscle was lighter in MED group (0.12±0.05 vs. 0.22±0.04, t=-2.428, P<0.05). For intraoperative and postoperative complications, 1 case of dural sac rupture occurred in both groups. Gelatin sponge immediately with fibrin glue was used for plugging up, no postoperative cerebrospinal fluid leakage was found. In Quadrant channel group, 1 case had less blood supply of skin incision edges and epidermal necrosis while the other case had fat liquefaction.@*Conclusion@#Compared with the aid of Quadrant, MIS-TLIF assisted with MED had less blood loss, less trauma and faster recovery and could reduce the incidence of postoperative incision complication.
RESUMEN
Dopa preparations are currently first choice for the clinical treatment of Parkinson' s disease. With the application time extension and the dose increase of dopa preparations, the therapeutic effect is smaller and smaller, while the side effects are more and more significant, which have become the main problems affecting their clinical application. The current researches showed that the combination of traditional Chinese medicines and dopa preparations can improve the efficacy, decrease the dose of western medicines, reduce the adverse effects and so on. The paper reviewed the progress in the combination of dopa preparations and traditional Chinese medicines in the treatment of Parkinson' s disease in recent ten years.
RESUMEN
Vinblastines as third-generation chemotherapy drugs are widely used in the treatment of a variety of cancers.Among them, vinorelbine (NVB) is a first-line chemotherapy drug for non-small cell lung cancer, while its side effects often limit its clinical use.There are more and more clinical studies show that Chinese medicine and NVB in the chemotherapy program has a synergistic anti-tumor effect, which can improve quality of life and immunity of patients, and reduce such side reactions as gastrointestinal reactions, bone marrow suppression and so on.In this paper, the application progress in traditional Chinese medicine combined with vinblastine in the treatment of lung cancer in recent ten years was reviewed.
RESUMEN
Objective To explore the characteristics and laws of burned children,and to find the coping strategies on preventing and reducing the incidence of pediatric burns.Methods The age distribution,burn causes, degree of burn,easy -happening months and on -site treatment of 978 children under 12 years old were retrospective-ly analyzed.Results 978 pediatric burns patients made up 55.4% of all burned patients among which there were 601 male patients and 377 female patients.Most of them were 1 -3 years old.The main reason of burn was hot liquid. Most of them were minor and moderate burned.The easy -happing months were from May to September.Only 11.0%of these children were correctly treated.Most burn children were from countryside.Conclusion The main reasons of children being burned are poor management of hot liquid,carelessness and the indifference of safety consciousness. The cases of burned children are regular.It is important to strengthen the publicity and education of precaution and the consciousness of safety protection of custodian.The publicity of knowledge about burning safety and correct on -site treatment are important for prevention and cure of burned children.
RESUMEN
Objective To explore the role of toll-like receptor (TLR)/nitric oxide (NO) pathway in cervical tumor with high risk human papillomavirus (hrHPV) infection.Methods (1)Study was based on 36 women with nonmalignantcervical tissue as control group and 36 women with squamous cell cervical cancer (SCC),all with hrHPV infection which were assessed by using 14 types hrHPV E6/E7 mRNA real-time PCR kit.The amount of NO was detected by Griess reaction,the expression of inducible nitric oxide synthase (iNOS) was detected by immunohistochemistry (IHC).The mRNA expression of TLR3,TLR4,TLR7,TLR8,TLR9,nuclear factor-κB (NF-κB) p65 and iNOS in control and SCC epithelium which was captured by laser capture microdissection (LCM) were determined.(2)The expressions of TLR4 in CaSki,HeLa and C33a were detected by cell immunofluorescence method.The mRNA and protein expression of TLR/NO pathway transduction molecules including TLR4,NF-κBp65 and iNOS in CaSki,HeLa and C33a cell lines were detected by real-time PCR and western blot.Results (1)The level of NO was much higher in SCC group than that in control group [(42.92±0.36) μmol/L vs (15.49±0.24) μmol/L;P＜0.05].iNOS was detected in 75％ (27 cases) of patients with squamous cervical carcinoma,while only 6％ (2 cases) of normal controls were confirmed with positve result (P＜0.05).TLR/NO pathway maybe activated in SCC,for the mRNA levels of TLR3,TLR4,TLR7,TLR8,NF-κBp65 and iNOS increased significantly when compared to control group (all P＜0.05),and the greatest change in the expression level of TLR in SCC was spotted on TLR4(7.41±0.39 vs 1.86±0.21).(2)The results of immunofluorescence showed that TLR4 was located at plasma membrance of hrHPV positive HeLa and CaSki cells,while the integral optical density of TLR4 in HeLa cells (3 599±427) or CaSki cells (2 080±456) were higher than that in C33a cells (730±96;P＜0.05).The mRNA and protein level of TLR4,NF-κBp65 and iNOS in HeLa and CaSki cells were higher than those of C33a cells (P＜0.05).Conclusion TLR4/NO pathway is highly expressed in cervical cancer with hrHPV infection,while the pathway may be involved in cervical tumorigenesis with hrHPV infection.
RESUMEN
Objective To investigate whether immunization mice with an immune tolerogenic vac-cine could inhibit the occurrence of allergic asthma through regulating the inflammatory T cells . Methods The BALB/c mice were randomly divided into 5 groups, with 10 mice per group.The mice in different groups were treated with different immunization strategies , which were 100 μl of phosphate buffer ( PBS) for the negative control , 10 μg of ovalbumin for the unrelated antigen control , 10 μg of dexametha-sone for group 3, 10μg of ovalbumin protein and 10μg dexamethasone for group 4 and 100 μg of ovalbumin protein and 100 μg of dexamethasone for group 5.The mice were immunized subcutaneously on days 1, 4, 7, and 14.Seven days after the last immunization , all mice were used for the induction of allergic asthma . The incidences of asthma in mice from different groups were evaluated 24 hours after the induction .The eval-uation indicators included pathological changes in lung tissues , infiltration of inflammatory cells in bronchial alveolar lavage fluid , antibody in serum samples and allergic responses .Results Immunization mice with the immune tolerogenic vaccine significantly reduced the infiltration of inflammatory cells in lung tissues , de-creased the levels of IgE and IgG 1 antibodies in serum samples and alleviated the injuries and pathological changes in lung tissues.However, the percentages of CD4+CD25+Foxp3+regulatory T cells to CD4+T popu-lations were significantly increased .Moreover, immunization mice with the tolerogenic vaccine could inhibit the expression of Th2 type cytokines .Conclusion Immunization mice with the tolerogenic vaccine could in-duce high levels of regulatory T cells , reduce the infiltration of inflammatory T cells in lung tissues and in-hibit the expression of Th2 cytokines, resulting in the inhibited occurrence of asthma in the murine model .
