Objective To research the recent efficacy of advanced cervical cancer treated with two different ways of uterine artery intervention and systemic intravenous chemotherapy respectively combined with radiotherapy.Methods Eighty-two patients with stage Ⅱ B-ⅣA cervical cancer confimed by pathology were given systemic intravenous chemotherapy combined with radiotherapy(vein group,S0 cases)and uterine artery intervention chemotherapy combined with radiotherapy(intervention group,32 cases).The therapeutic effect and remission rate of parametrium were compared.Results The total therapeutic effect rate in vein group was 90.0％(45/50),and intervention group was 93.8％(30/32),there was no significant difference between two groups(P ＞ 0.05).The remission rate of parametrium in vein group was 50.0％ (25/50),and intervention group was 75.0％(24/32),there was significant difference between two groups (P ＜ 0.05).Conclusion The effect of uterine artery intervention chemotherapy for parametrium is better than that of systemic intravenous chemotherapy.

Objective To evaluate the effect of prosthetic rehabilitation and analyze the exercise training program with myoelectric signal for upper limb stumps.Methods Twenty canes with 22 upper limb stumps were treated with exercise for strength training,muscle contraction and control training and the complication of stump were managed.The myoelectrlc signal of upper limb stumps were detected and the stumps were trained with electronic biofeedback software system,including basic signal of biofeedback training and visual biofeedback training.Then the myoelectric prostheses were assembled.Results After prosthetic rehabilitation and myoelectfic signal training,there Wan no significant atrophy of muscle of stumps,muscle strength and range of motion of these twenty limb stumps increased.The amputees could control muscle contraction and grasp,pinch,wrist rotation,elbow extension or flexion consciously.Twenty myoelectrie prostheses were assembled.Conclusion The prosthetic rehabilitation and myoelectric signal training of limb stump is important for assembling myoelectric prosthesis.

Objective:To explore the outcome of soft tissue sarcoma (STS) on patients with soft tissue metastasis. Methods:We ana-lyzed 25 STS patients with soft tissue metastasis primarily localized on extremity and trunk. The study was conducted from June 2010 to June 2016 by retrospective analysis of the clinical and pathological characteristics of the patients. The assessed endpoints were overall survival. Results:Six patients (24%) had synchronous soft tissue metastasis, and 19 patients (76%) had metachronous metasta-sis. The average time for primary tumor recession of metastatic lesions was 45.3 months. Metastases were most common in parts of the trunk in 18 patients (72%), followed by the head and neck in 5 patients (20%). Eleven patients (44%) with lung metastasis had poor prognosis. Conclusion:STS occurred more rarely in soft tissue metastasis than in pulmonary metastasis. Neoadjuvant chemotherapy and surgical treatment were the major therapies employed. Targeted therapy as a new treatment rendered good results.

Objective To investigate the changes of extracellular histones during the course of acute liver failure in mice as well as its therapeutic potential.Methods WT mice (C57BL/6) were randomly (random number) allocated to inducing acute liver failure by lethal doses of GalN/LPS injected i.p.Hepatic function,apoptosis of hepatocytes and histological indexes were measured at different intervals following GalN/LPS challenge.The levels of extracellular histones were determined by using ELISA and Western blot methods.Meanwhile,GalN/LPS-treated mice were administered with anti-histone H3 and antihistone H4 neutralized antibodies,respectively.Results Administration of GalN/LPS to mice caused acute liver failure,characterized by significant elevation of plasma ALT levels and massive hepatocyte apoptosis or necrosis.All mice died within 9-12 hours.The levels of nucleosomes and extracellular histones H3 and H4 were increased considerably in a time-dependent manner.The survival rates in GalN/LPS-treated mice were improved remarkably following administration of anti-histone H3 and H4 neutralized antibodies (P =0.037,P =0.025),likely due to the significant inhibition of TNF-production.Conclusions Extracellular histones are an important mediator implicated in the pathogenesis of acute liver failure.Anti-histones show promising potential in the treatment of acute liver failure,which deserves further investigation in the future.

Objective:To evaluate the accuracy and feasibility of sentinel lymph node biopsy (SLNB) marked by 99Tcm-IT-Ritux-imab and to discuss the clinical value of the method in diagnosis and treatment of cutaneous melanoma. Methods:A total of 67 patients with cutaneous malignant melanoma received 99Tcm-IT-Rituximab-tagged SLNB from March 2008 to March 2012. Lymphoscintigra-phy was conducted 30 min to 1 h after intra-dermal injection of 99Tcm-IT-Rituximab. Subsequently, the surgery of SLNB was carried out using gamma probe. The detection and positive rates of SLNB were counted. The relationship between the status and the clinical features of the sentinel lymph node (SLN) was analyzed, such as the T stage, ulceration, age, gender, and location. The influence of SLN status on overall survival (OS) and disease-free survival (DFS) was evaluated. Results:SLNs were detected in all the 67 patients by SPECT and gamma detector, with detection rate of 100%. Fifteen patients had SLN metastasis, and the positive rate was 22.4%. Chi-square indicates that SLN metastasis is associated with age, T stage, and ulceration (P<0.05). A total of 63 patients were followed up for 24-69 months, and the median follow up time was 43 months. Kaplan-Meier survival analysis shows that both OS and DFS in the SLN-negative group are better than those in the SLN-positive group (OS:93.9%vs. 57.1%, P<0.01;DFS:79.6%versus 28.6%, P<0.01). Cox-regression multiple factors analysis suggests that both SLN status and T stage are independent factors that affect the DFS of malignant melanoma. Conclusion:SLNB assisted by 99Tcm-IT-Rituximab can well reflect the state of lymph node metastasis and is es-sential for accurate staging, prognosis judging, and treatment guiding. Its operation procedure is simple with high accuracy, and the im-aging status is stable. Therefore, it is convenient and feasible as a means of SLNB.

BACKGROUND:Autologous bone graft is the best method to repair bone defects after tumor curettage, but its shortcomings are as folows: increased surgical trauma, sequelae at bone graft site such as infection and pain, and a limited amount of autologous bone. OBJECTIVE:To analyze the effectiveness of xenograft and calcium sulphate artificial bone in treating bone defects after benign bone tumor removed. METHODS:Totaly 26 cases of benign bone tumor were selected, including 8 cases of giant celltumor, 5 of enchondroma, 4 of fibrous histiocytoma, 3 of bone fibrous dysplasia, 2 of non-ossifying fibroma, 2 cases of bone cysts, 1 of aneurysmal bone cyst and 1 of aneurysmal bone cyst and 1 case of chondroblastoma. Of the 26 cases, 12 cases underwent calcium sulphate pelets alone to fil bone defects after benign bone tumor removed, 6 cases were subjected to xenograft alone, and 8 cases were treated with calcium sulphate pelets combined with xenograft. The X-rays were taken at 1 week, 3 months, and 1 year after the operation in al patients to assess the bone healing process. RESULTS AND CONCLUSION:Al the patients were folowed up for 36-72 months. The absorption of calcium sulphate appeared to be absorbed earlier, the earlier absorption appearance could be observed as earlier as 1 month after the implantation, and most calcium sulphate was absolved and replaced by new bone at 3 months after the operation. The xenograft bone was degraded at 3 months post implantation and new bone formed. Osseo integration of the graft was observed at the periphery of the implant at 6 months post implantation. One year post implantation, trabecular bone was observed at the site with uniform bone density. In the combined group, thecalcium sulphate pelets were absorbed earlier and new bone formed earlier than the calcium sulphate alone group, and the xenograft absorbed later than the calcium sulphate pelets. Generaly, bony union was detectable 1 year after operation. These findings indicate that xenograft and calcium sulphate in treating benign bone tumor have acquired good results, which can be used as a substitute of autologous bone.

Objective To establish the reference range of thyroid function from the normal pregnant women in different pregnant period in Hanzhong region.Methods According to the NACB inclusion criteria,collected local resident pregnant women 4 031 cases,from July 2012 to December 2015.With the combination of random sampling,stratified sampling and cluster sampling,thyroid hormone levels were measured by a fully automated chemiluminescence analyzer and its accompanying reagents.All patients were divided into three groups:998 cases in early pregnancy (T1),1 543 cases in mid-pregnancy (T2),1 490 cases in late pregnancy (T3),and 105 cases of non-pregnant women in childbearing age (T0) were selected as control group.Results The levels of thyroid hormones were different among three periods of pregnant women.TSH were 0.25～5.32,0.42～6.26 and 0.61～7.68 mIU/L respectively in the early,middle and late stages.FT3 were 3.54～6.04,3.57～5.94 and 2.93～5.40 pmol/L,respectively.FT4 was 7.11～16.88,6.78～16.94 and 6.03～16.87 pmol/L.Thyroid hormone levels in pregnant women compared with non-pregnant women,there were significant differences (TSH:x2=233.183,P＜0.05,FT4:x2 =388.12,P＜0.05 and FT3:x2 =558.795,P＜0.05).TSH were lower in early pregnant women comparing to non-pregnancy women,and higher in middle-late pregnant women.The change of FT3 and FT4 were consistent,and reduced with the extension of pregnancy comparing to non-pregnancy women.Conclusion The level of thyroid function in pregnant women were different from non-pregnant women.and the normal reference range of local pregnant specific thyroid hormone should be established.

Treatment resistant depression is a common and severe mental disorder associated with significant burden of disease .Most individuals receiving conventional pharmacotheraphy fail to achieve and sustain remission.So this is still one of the difficult challenges for the psychiatrist .Much of the research pro-vided indications that the efficacy of treatment for the disease was not optimistic, but the treatment was still made great progress .The common treatments for this disease included pharmacotherapy,psychotherapy,elec-troconvulsive therapy(ECT),transcranial magnetic stimulation (TMS),magnetic resonance guided focused ultrasound surgery( MRgFUS) ,deep brain stimulation ( DBS) ,aerobic exercise,light therapy and so on.Each therapeutic strategy has its own features, and could be suitable or unsuitable in some situations.The high rates of non-remission with first-line treatment strategies make the combination of antidepressant and non-drug treatments to be the new trend of the treatments for treatment resistant depression in the future.

Objective: To learn the characteristics of road traffic injury cases caused by electric bicycles in Changshan County from 2013 to 2016,and to provide evidence for the development of preventive measures or traffic regulations. Methods: The surveillance data of road traffic injuries caused by electric bicycles was collected from the hospital-based product injury monitoring system in Changshan County during 2013-2016. The descriptive epidemiologic analysis on demographic characteristics,body parts and degree of injury was conducted. Results: A total of 7 078 road traffic injury cases caused by electric bicycles were reported from 2013 to 2016,accounting for 49.58% of road traffic injuries. The proportion of electric bicycle injuries was higher in females than in males（P<0.05）. There were 4 893 cases aged 30-64 years,accounting for 69.13%;5 562 cases with an education level of junior high school or below,accounting for 78.58%;2 005 cases occurring from July to September,accounting for 28.33%;5 216 cases occurring from 8:00 to 19:00,accounting for 73.69%. The injury mainly lay in head,accounting for 30.77%（2 178 cases）. Most injuries were flesh wounds,accounting for 74.96%（5 306 cases）. Most cases went home after treatment,accounting for 76.09%（5 386 cases）. Conclusion The incidence of road traffic injury caused by electric bicycles is high in Changshan County. Improving the safety awareness of women and people aged 30-64 years should be focused on.

Objective:To analyze the clinical prognostic factors of liposarcoma on the extremities and trunk, as well as to retrospectively analyze the effect of adjuvant radiotherapy and chemotherapy on liposarcoma of the extremities. Methods:Patients with liposarcoma of the extremities treated in our hospital from July 1, 2007 to December 31, 2012 were followed up. The relationship of clinical prognostic factors with gender, age, location, depth, and size of the tumors, as well as the histological grade and admission status, were statistically analyzed. The effects of adjuvant radiotherapy or chemotherapy on overall survival (OS) and disease free survival (DFS) were evaluated. Results:A total of 82 patients with extremity liposarcoma received surgery-based comprehensive treatment in our hospital. Of the total patients, 73 received a 24-month to 88-month satisfied follow-up;the median follow-up time was 47 months. The OS rate was 83.6%(61/73), and the DFS rate was 68.5%(50/73). Multivariate Cox regression analysis showed that the tumor location, histological grade, and admission status were the independent correlative factors influencing DFS, and the age and pathologic grading were the independent correlative factors influencing the OS. Kaplan-Meier survival analysis showed that radiation therapy can significantly improve the DFS and OS of the G2 and G3-grade liposarcoma (DFS:59.1 months vs. 28.4 months, P<0.01;OS:70.8 months vs. 55.1 months, P<0.05). Significant difference was not found in the effect of chemotherapy on OS and DFS. Conclusion:The prognosis of liposarcoma was significantly associated with the pathologic grades and subtypes. Auxiliary radiotherapy could improve the survival and prognosis of G2 and G3 liposarcoma of the extremities, but the role of chemotherapy in treating liposarcoma remained unclear.
