Purpose:To determine the impact of serum tissue polypeptide specific antigen (TPS) in the treatment for advanced cancer patients. Methods:Serum TPS was examined in 60 advanced cancer cases. 42 of the patients received hepatic arterial chemoembolization or chemotherapy. For those with tumors derived from digestive system, TPS monitoring was performed in serial during the therapeutic courses. Results:No significant differentiation was observed in terms of age, gender, disease or tumor stage. Patients with initial TPS lower than 300 U/L had the most favorable response rate to treatment (PR,CR or MR) of 52.94%, while those with initial TPS higher than 1000 U/L showed no evidence of remission after therapy. 55.56% of the latter developed into PD ( P

BACKGROUND:With the improvement of cervical posterior surgical techniques, lateral mass screw fixation technology has been widely used in the reconstruction surgery of the cervical spine for stability. However, currently, the finite element study on the lateral mass screw fixation reconstruction of the cervical spine is rare. OBJECTIVE:To establish a fine normal lower cervical spine (C3-C7 ) three-dimensional finite element model and a reconstructed finite element model with three-segment laminectomy with lateral mass screw fixation. Then, to do an initial biomechanical analysis of the lateral mass screw fixation reconstructed lower cervical finite element model. METHODS:We col ected a normal female volunteer aged 30 years old to do CT scan for the whole cervical spine. The Dicom data were obtained. Then, the CT scanning images were dealt with software Mimics 10.01, Geomagic Studio 12.0, Solidworks2012, HyperMesh 10.1 and Abaqus 6.12 software to build the normal lower cervical spine (C 3-C7 ) finite element model, the laminectomy finite element model and the rebuilt finite element model. At last, we analyzed the stress changes of reconstructed models under the state of flexion, extension, lateral bending and rotational motion. RESULTS AND CONCLUSION:The lower cervical spine finite element model contained 503 911 elements and 93 390 nodes with a fine realistic appearance. It successful y passed the validation. The surgical procedure was completed in the software, and the lateral mass screw fixation reconstruction finite element model has been established. Lateral mass screw fixation system provides good stability for the postoperative finite element model. The activity of rebuilt finite element model is much lower than the normal finite element model. In the extension condition, the stress of lateral mass screw fixation system becomes strong.

OBJECTIVE: To evaluate the treatment effect, quality of life and side-effect of transcatheter arterial chemoembolization (TACE) and traditional Chinese medicine (TCM) in treating metastatic liver cancer. METHODS: Thirty-nine cases of colon metastatic liver cancer were randomly divided into two groups. Both TACE and TCM were used in the treatment group, while only TACE was used in the control group. The drug used in TACE included floxuridine, pirarubicin, cisplatin, and the herbs for strengthening the spleen and regulating Qi were used in TCM. RESULTS: The response rate in the treatment group was 30% (45% including minor remission patients), and the median survival time was 18.6 months. While in the control group the response rate was 15.8% (36.8% including minor remission patients), and the median survival time was 14.3 months. The 1-, 2-, 3- year survival rates of treatment group and the control group were 70.2%, 40.3%, 13.0% and 68.7%, 29.5%, 10.3% respectively. There were fewer other organ metastases in the treatment group. The score from the EORTC quality of life questionnaire QLQ-C30 in treatment group was higher than that in the control group. CONCLUSION: Integration of TACE and TCM in treating colon metastatic liver cancer has better results.

Objective To analyze the profile of dermcidin (DCD) changes in different stages of acute coronary syndrome (ACS) by quantifying the serum 4 183Da DCD peptide fragment deriving from different ACS patients treated with early antithrombotic therapy.Methods A total of 118 patients with confirmed diagnosis of ACS were enrolled. Immediately after visiting a doctor, the venous blood was collected and afterwards instantly the patient was given orally 300 mg of aspirin and 300 mg clopidogrel, and according to the patient's condition and the consent of his/her or acknowledgement of family members achieved, emergency percutaneous coronary interference (PCI) or thrombolysis or conservative treatment was adopted separately. After anti-thrombotic treatment, at 2, 4, 6, 8, 10, 12, 16, 20, 24, 32, 40, 48, 60 and 72 hours, venous blood was collected and serum isolated respectively. The concentration of 4 183Da DCD fragment in serum was determined by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). Simultaneously, the myoglobin (Myo), cardiac troponin I (cTnI) and MB isoenzyme of creatine kinase (CK-MB) were also detected.Results The mean relative strength of nature logarithmic transformations of 4 183Da DCD fragment of 118 patients with ACS was 2.75±1.02 before treatment on admission, and after intervention therapy (mainly antithrombotic therapy) it was decreased to 1.84±1.19 (P = 0.005) and 1.74±1.12 (P = 0.000) at 2 hours and 4 hours, respectively, and then after 4 hours it was slightly elevated. 4 183Da polypeptide increased earlier than myocardial injury markers.Conclusion Aspirin and clopidogrel can significantly decrease the concentration of 4 183Da DCD peptide fragment in serum in patients with ACS, which indicates that the DCD fragment could be used as one of the indexes for observation on early efficacy of antithrombotic therapy.

Objective To explore a rapid,simple and effective therapy for serious pneumothorax which could be used in pre-hospital and in-hospital first-aid.Methods Sixty-seven patients were randomly divided into the observation group and control group .Patients in the observation group were treated using laparoscopic trocar for rapidly closed thoracic drainage,and patients in the control group were treated by using the traditional large caliber drainage tube and the intercostal incision method of conventional closed thoracic drainage.The operation time,remaining time of drainage,length of stay,effective rate,and complications,including of postoperative pain,hemorrhage,subcutaneous emphysema and infection were observed in both groups. Results The total effective rate was 94.1%(32/34) in the observation group,which was significantly higher than that in the control group(90.9%,30/33)(x2=1.876,P＞0.05).No significant difference was found on the remaining time of drainage and length of stay between the two groups(remaining time of drainage:[4.56±1.65]d vs.[6.26±3.45]d;length of stay:(6.0±2.6)d vs.(6.7±2.2)d ,t=1.335 and 0.779,respectively,Ps＞0.05).The operation time of using laparoscopic trocar was significantly lower than that of the control group((5.00±1.28)min vs.(15.00±4.03)min,t=3.031,P＜0.05).The incision length was(0.95±0.11)cm in the observational group,which was significantly lower than that in the control group((2.41±0.52)cm ,t=2.585,P＜0.05).Postoperative pain occurred in 14.7%(5/34) of patients in the observational group,which was significantly lower than that in the control group(87.9%(29/33))(t=2.983,P＜0.05).In the observational group no hemorrhage and infection occurred,whereas in the control group the hemorrhage and infection rate was 36%(12/33) and 33%(11/33),respectively(x2=5.880 and 3.687,respectively,Ps＜0.05). Conclusion The use of laparoscopic trocar for rapidly closed thoracic drainage in the treatment of serious pneu-mothorax is simple,easy,convenient,effective and reliable,with few complications.This therapy is suitable for using in pre-hospital and in-hospital first-aid.

Objective To evaluate the clinical effect of the chest orthosis on patients with multiple rib or(and) sternal fracture in early period of closed chest trauma.Methods Patients with multiple fractured of ribs or (and) sternal fracture were divided into control group (n =16)treated with the traditional fixation methods ( thoracic girdle added with folding towels) and experimental group ( n =30 ) treated with chest orthosis between January 2009 and December 2011.Correlated parameters of these patients in the two groups,including pain,indexes of blood gas analysis,pulmonary complications and hospitalization time were evaluated.Results There were significant differences on visual analogue scale(VAS) [ (4.45 ±2.23) vs (8.15 ±2.02),t =2.921,P ＜0.01 ],blood gas analysis including PaO2 [ 88.16 ± 9.12) mm Hg vs (77.22 ± 6.24 ) mm Hg,t =2.413,P ＜0.05] andPaCO2[ (40.91 ±3.40)mm Hg vs (46.06 ±5.40)mm Hg,t =2.335,P＜0.05] between experimental group and control group.The incidence rate of pulmonary complications in experimental group was significantly lower than that in control group [ 17％ ( 5/30 ) vs 44％ ( 7/16 ),x2 =23.478,P ＜ 0.05 ].And hospitalization time in experimental group was significantly shorter compared with control group[ (7.26 ± 4.17) d vs ( 14.26 ±3.53)d,t =2.430,P ＜0.05].Conclusion The chest orthosis in early treatment of chest trauma can reduce the pain and improve the condition of patients,and it is a simple,effective and cheap method with significant clinical effect.

Objective:To investigate the clinical effect of myocutaneous flap combined with antibiotic-loaded polymethylmethacrylate (PMMA) cement in the treatment of Cierny-Mader type III-IV osteomyelitis.Methods:From April, 2014 to March, 2019, 53 patients with Cierny-Mader type III-IV chronic osteomyelitis were treated with myocutaneous flap combined with antibiotic-loaded PMMA cement. There were 33 males and 20 females, with an average age of (52.2±3.0) (29-78) years old. The area of the wound ranged from 2.0 cm×2.0 cm to 14.0 cm×28.0 cm. All flaps were closed directly. There were 23 patients who were removed the cement at 3 months after surgery, and the other 30 were not. After the surgery, the blood supply of the flap, the effusion of the wound, the complications of the donor area, signs of fresh bone destruction on X-ray and the color, the texture and scar of the flap were observed in the follow-up at the clinic.Results:Forty-nine cases healed in one stage, and 4 had delayed healing. Postoperative vascular crisis occurred in 6 cases and releasesd by prompt surgical exploration. The patients were followed-up for 0.6-3.0 years, with an average of 18 months. All 53 myocutaneous flaps completely survived ultimately. The color of flaps was similar to the recipient areas, and the flaps were smooth and soft and satisfactory in appearance. During the follow-up period, X-ray examination showed no sign of fresh bone destruction. Osteomyelitis was significantly controlled. There was no inflammation reaction such as swelling, pain, ulceration and effusion of the flaps, and there was no recurrence of osteomyelitis. All donor areas healed primarily.Conclusion:Myocutaneous flap combined with antibiotic-loaded PMMA cement has achieved good anti-infection effects in satisfactory results, less postoperative complications and low recurrence rate in the treatment of Cierny-Mader type III-IV osteomyelitis. Application and promotion of such technique would deliver good benefits.
