Objective To investigate the changes of amplitude of low frequency fluctuation (ALFF) of the resting state fMRI in cognitively impaired Parkinson' s disease patients and discuss its underling neurophysiological mechanism.Methods Blood oxygen level-dependent low-frequency amplitude (ALFF) in resting-state functional magnetic resonance imaging were calculated in 16 healthy controls(HC) and 29 idiopathic Parkinson's disease patients (16 of which were patients with cognitive normal,PDCN and 13 with cognitive impairment,PDCI).The brain regions showing increased and decreased ALFF in patients were demonstrated by comparing normal subjects with 2-sample t-test with threshold of P＜ 0.05 and the analysis of the relationship between the different regions of the brain activity and cognitive function tests scores were also analyzed.Results Compared with PDCN,the PDCI patients showed decreased activity in the caudate nucleus (-3,9,12),occipital lobe (0,-78,-15) and medial temporal lobe (42,9,-27) and increased activity in the superior frontal gyrus (9,63,24).PDCI patients showed increased activity mainly in the precuneus and inferior parietal lobules compared with controls.Additionally,the regions with ALFF changes had significant correlations with the cognitive performance of patients as measured by Montreal cognitive test(Beijing Version) and neuropsychological tests (including memory,attention,visuospatial functions and executive function).Conclusion The results demonstrate that there is a specific pattern of intrinsic activity in PDCI providing insights into neurophysiological mechanisms of the Parkinson's disease dementia.

Objective To evaluate the diagnostic performances of seven estimation formulas for glomerular filtration rate (GFR) in pre-operative patients with renal cell carcinoma.Methods A total of 386 pre-operative patients with renal cell carcinoma in the first affiliated hospital of Chongqing medical university from January 2012 to October 2014 were selected.All the patients' GFRs were measured by the renal dynamic imagingwith 99mTc-DTPA as reference (rGFR) and the seven GFR estimation equations (eGFR) were compared with the rGFR respectively.Their correlations and consistencies were observed with spearman correlation analysis and Bland and Altman analysis.The diagnostic sensitivity,specificity and likelihood ratios were calculated and the eGFR accuracies were assessed with receiver operator curve (ROC) analysis.Results The correlations between the rGFR and eGFRs were significantly (P＜0.001).In addition,CKD-EPI-Asian Crea and Ruijin formula were more accurate than others in different stages with larger ROC area in diagnosing renal cell carcinoma.Conclusion There were significant correlations between the eGFRs and rGFR,but some deviations existed.CKD-EPI-Asian Crea and Ruijin formula were more suitable for assessment of eGFR of pre-operative patients with renal cell carcinoma.However,both of these equations had a few limitations.

Objective To investigate the prevalence of latent tuberculosis infection(LTBI),and to identify the risk factors in primary schoolchildren from Shanghai through the population-based field investigation combined with the tuberculosis infection enzyme-linked immunospot assay(T-SPOT.TB)assay.Methods The children in grade 4 and 5 were enrolled from four primary schools in Pudong new district and Yangpu district of Shanghai.Questionnaire interview was applied to investigate the soeiodemographic and clinical information related to LTBI.The T-SPOT.TB assay was used to detect LTBI in the enrolled subjects.Univaitate and multivariate analyses were used to identify the risk factors associated with LTBI among the primary schoolchildren.Results Totally 472 schoolchildren were enrolled in the present study,with 439(93.0%)being vaccinated with bacillus calmette-guerin (BCG) and ten (2.1%) having contact history with tuberculosis (TB) patients.Among the 472 eligible subjects,16(3.4%) children were T-SPOT.TB positive,who had no clinical symptoms andsigns relevant to TB and were defined as LTBI.The LTBI prevalence in BCG vaccinated and unvaccinated children were 2.7% and 12.1%,respectively (OR:6.972;95%CI:1.834-26.500);those in TB contacts and children without TB contact history were 30.0% and 2.8%, respectively (OR: 16. 38; 95% CI: 3. 692-72. 700). Conclusions The prevalence of LTBI among senior schoolchildren in Shanghai is 3.4%. BCG vaccination is protective for children from LTBI, while daily contacts with TB patients increases the risk of LTBI in schoolchildren.

Objective To develop and optimize a module for the automatic production of N-succinimidyl-4-[18F] fluorobenzoate (18F-SFB) that is used for further 18F labelling C2A domain of Synaptotagmin Ⅰ . The conjugated compound was applied for detecting the tumor apoptosis in rabbit model after chemotherapy. Methods GE TRACERlab and TRACERlab FXF-N modules were modified and programmed to automatically produce 18 F-SFB which was further analyzed by high performance liquid chromatography (HPLC).C2A-glutathione S transferase (GST) was conjugated with 18F-SFB (18F-FB-C2A-GST) and subsequently purified by HPLC. Two rabbits grafted with VX2 lung cancer were first treated with chemotherapy and then,37 MBq of 18F-FB-C2A-GST was administered via the auricular vein. Serial PET/CT imagings were performed at 0.5, 1 and 2 h post-injection respectively. Tumor apoptosis was examined by pathological study. Results The TRACERlab FXFoG and TRACERlab FXF-N modules were successfully adapted to synthesize18F-SFB, with the radiochenmical yield (76.41 ±4.00)% (n = 10), the corrected yield (45.43 ±5.90 ) % and the radiochemical purity about 95%. The whole procedure for labeling 18 F-SFB was about 87 min.From PET/CT imagings, significant uptake was found in the tumor after chemotherapy, but no obvious up-take was found in heart, lungs and liver. HE staining demonstrated large number of apoptotic bodies within the tumor tissues. Conclusions 18 F-SFB can be automatically synthesized. 18F-FB-C2A-GST might be useful for the detection of apoptosis in tumor after chemotherapy.

BACKGROUND: Reducing perioperative blood loss in total hip arthroplasty is a hot topic for joint surgeons. Both intravenous infusion and intra-articular injection of tranexamic acid significantly reduce perioperative blood loss, blood transfusion volume, and need for blood transfusion in patients undergoing total hip arthroplasty. However, differences between the intravenous and intra-articular methods are not clear.OBJECTIVE: To evaluate the effects of these two tranexamic acid administration methods on perioperative blood loss in patients undergoing total hip arthroplasty.METHODS: We are conducting a prospective, single-center, open-label, randomized, controlled clinical trial at the Tengzhou Central People's Hospital, China. Ninety patients undergoing unilateral total hip arthroplasty have been randomized into three groups. In the intravenous infusion group (n=30), 15 mg/kg tranexamic acid diluted in 100 mL physiological saline was infused intravenously at the beginning of surgery and 20 mL of physiological saline was injected intra-articularly after deep fascia suturing. In the intra-articular injection group (n=30), 100 mL of physiological saline was infused intravenously at the beginning of surgery and a mixture of 1.5 g tranexamic acid and 20 mL physiological saline was injected intra-articularly after deep fascia suturing. In the control group (n=30), 100 mL of physiological saline was infused intravenously at the beginning of surgery and 20 mL of physiological saline was injected intra-articularly after deep fascia suturing. The primary outcome is hidden blood loss at 1 and 3 days postoperatively. The secondary outcomes are visible blood loss, need for blood transfusion, and mean blood transfusion volume intraoperatively and on days 1 and 3 postoperatively. Other outcomes are the incidence of adverse reactions and complications within 3 months of surgery. The study protocol has been approved by the Ethics Committee of Tengzhou Central People's Hospital of China, approval number 2015-026. All protocols will be performed in accordance with the Ethical Principles for Medical Research Involving Human Subjects in the Declaration of Helsinki. Written informed consent was provided by each patient and their family members after they indicated that they fully understood the treatment plan.DISCUSSION: This trial was designed in April 2015. Cases were collected in July 2015. Data analysis will be finished in December 2017. This study is designed to investigate the effects of intravenous infusion versus intra-articular injection of tranexamic acid on perioperative blood loss in patients undergoing total hip arthroplasty to determine the more effective mode of administration.

BACKGROUND:Increasing reports have focused on the application of tranexamic acid to reduce bleeding during total knee arthroplasty, but its usage method remains controversial.
OBJECTIVE:To explore the impact of topical articular application of tranexamic acid and intravenous application of tranexamic acid on blood loss during primary unilateral total knee arthroplasty.
METHODS:According to randomized control ed principle, 90 patients who received unilateral total knee arthroplasty in the Tengzhou Central People’s Hospital from October 2013 to December 2014 were enrol ed in this study, and randomly assigned to intravenous injection group and topical injection group (n=45). Patients in the intravenous injection group were given tranexamic acid by intravenous injection (10 mg/kg, maximum 1.2 g) during the induction of anaesthesia. Patients in the topical injection group were given intraarticularly tranexamic acid (2 g dissolved in 50 mL physiological saline) before articular capsule suture and after prosthesis fixation. Drainage amount after replacement, hemoglobin and hematocrit on the next day after replacement, and the number of blood transfusion population were compared between the two groups. Simultaneously, clinical symptoms of pulmonary embolism and deep vein thrombosis in the lower limb were observed. If necessary, lower extremity vascular Doppler ultrasound was conducted.
RESULTS AND CONCLUSION:No significant differences in drainage amount after replacement, hemoglobin and hematocrit on the next day after replacement, the number of blood transfusion population, and the proportion of blood transfusion were detected between the two groups (P>0.05). No deep vein thrombosis was found in the lower limbs at 14 days after replacement in both groups. These findings confirm that compared with intravenous systemic application, periarticular topical application of tranexamic acid during total knee replacement could obtain identical effects on reducing blood loss and blood transfusion after surgery, and could avoid relevant complications of intravenous application of tranexamic acid.

BACKGROUND: Open reduction and internal fixation is commonest surgical method for calcaneal fractures, but its postoperative complications are troublesome. Thereafter, choosing an appropriate treatment scheme is of great significance for reducing postoperative complications and promoting patients' functional recovery. OBJECTIVE: To compare the curative efficacy of the modified minimally invasive internal fixation with cannulated screws through tarsal sinus and traditional extended lateral "L-shape" incision with plate fixation for calcaneal fractures. METHODS: Sixty-eight cases of unilateral calcaneal fractures (Sanders II and III) were selected, followed by treated with modified minimally invasive internal fixation with cannulated screws through tarsal sinus (modified group, n=33) or traditional extended lateral "L-shape" incision with plate fixation (traditional group, n=35). The operation time, blood loss, and Visual Analogue Scale scores were compared between two groups; the preoperarive and postoperative American Orthopedic Foot and Ankle Society scores, Bohler angle, and Gissane angle as well as postoperative complications were detected and compared between both groups. Besides, the postoperative pain, range of motion, and ankle stability were evaluated. RESULTS AND CONCLUSION: (1) The American Orthopedic Foot and Ankle Society scores at 6 months postoperatively in both two groups were significantly higher than those at baseline, and the scores in the modified group were significantly higher than those in the traditional group (P < 0.05). (2) The Bohler angle, Gissane angle, and calcaneal width in the modified group were significantly improved compared with the traditional group at 1 week, 6 and 12 months postoperatively (P < 0.05). (3) Compared with the traditional group, the operation time, blood loss, and Visual Analogue Scale scores in the modified group were significantly improved (P < 0.05). (4) The incidence of complications in the modified group was significantly lower than that in the traditional group (P < 0.05). (5) These results manifest that compared with the traditional extended lateral "L-shape" incision with plate fixation for calcaneal fractures, the modified minimally invasive internal fixation with cannulated screws through tarsal sinus can significantly alleviate pain, and improve the range of motion and stability of the ankle joint.
