Objective To evaluate three-axis otoconia maneuver (TOM) for benign paroxysmal positional vertigo (BPPV). Methods The data from twenty BPPV patients who received three-axis otoconia maneuver treatment and 20 BPPV patients who received canalith repositioning (CRP) maneuver treatment were analyzed retrospectively. Results There were 17 patients received 1 TOM session and 3 patients received 2 TOM sessions while 16 patients received 1 CRP session and 4 patients received 2 CRP sessions. The chi-square (x2) test was used in evaluating the association between two independent samples in a contingency table. Both methods had no statistically significant. The significance level for statistical tests was 5% (α = 0. 05). Conclusions Three-axis otoconia maneuver could be effective used in benign paroxysmal positional vertigo with the advantage of repeatedly practicable and instrumental.

OBJECTIVETo observe the effects of blood activating wind dissipating acupuncture (BAWDA) on blood pressure (BP) of prehypertension (PHT) patients.

METHODSTotally 60 PHT patients were assigned to the control group and the acupuncture group according to random digit table, 30 in each group. All patients were intervened by life style. BAWDA was additionally performed in patients in the acupuncture group for 6 weeks (30 times). The improvement of BP after intervened by acupuncture was observed. BP success rates and the proportion of PHT progressing to hypertension (HT) were also observed after 6-week intervention of acupuncture and at 1-year follow-up.

RESULTSSystolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after 6-week intervention in the acupuncture. The BP control rate was 56.7% (17/30 cases) in the acupuncture group vs.10.0% (3/30 cases) in the control group with statistical difference (chi2 = 14.70, P < 0.01). At 1-year follow-up BP success rate was 36.7% (11/30 cases) in the acupuncture group, remarkably higher than that of the control group [13.3%, (4/30 cases)] (chi2 = 4.36, P < 0.05).

CONCLUSIONSBAWDA showed BP regulating roles in a gradually stable decreasing tendency. It also could elevate BP success rate of PHT, and reduce the risk of PHT progressing to HT.

BACKGROUNDRheumatoid arthritis (RA) is a chronic, systemic autoimmune inflammatory disorder. Many methods have been used to observe the progress of RA. The purpose of this study was to observe the progress of RA in rats with 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT), magnetic resonance (MR) imaging and arthritis score, and analyze the relationships among different methods in evaluation of RA.

METHODSSixteen healthy Sprague Dawley (SD) rats about 8-week old were randomly assigned to a RA group and a control group. Bovine type II emulsified incomplete Freud's adjuvant was used to induce arthritis in the RA group. Arthritis score of the rats in two groups were recorded, and (18)F-FDG PET/CT, MR imaging were performed both on the corresponding rats every 3 days. All the rats were sacrificed at week 5, and histopathological examination was performed on rat knees stained with haematoxylin and eosin.

RESULTSThe arthritis score and the standard uptake value (SUV) of knee joints in RA rats increased with the progression of arthritis gradually. Both peaks of arthritis score and SUV appeared at 21 days after the first immune injection, then the arthritis score and SUV of knee joints decreased slowly. The arthritis scores of knee joints in RA rats were positively correlated with their SUV changes. The MR images were confirmed by the histopathological studies.

CONCLUSIONPET/CT can detect the earliest molecular metabolism changes of RA, and MR imaging can follow up the dynamical anatomical changes of RA, all of which indicated that PET/CT and MR imaging may be applied as useful tools to monitor the progress of RA.

OBJECTIVETo evaluate the differences in oncologic outcomes between inflammatory adhesion and malignant adhesion in patients with stage IIC colorectal cancer after multivisceral resection(MVR).

METHODSA retrospective review was undertaken of 287 patients who underwent MVR for stage IIC CRC, 120 patients for stage IIB, and 140 patients for IIIA. Patients were divided into two groups: inflammatory adhesion(IA) and malignant invasion(MI).

RESULTSThere were 153 patients with colon cancer and 135 patients with rectal cancer in the stage IIC group. The overall survival was significantly lower in the MI group at 5 years(38.5% vs. 59.4%, P<0.05). Stage IIC patients with IA had similar survival rate to the patients with stage IIB CRC. Compared to the MA group, patients with stage IIIA CRC showed significant differences in 5 years overall survival rate. Univariate analysis showed that differentiation, adhesion pattern, and complication were significant prognostic factors for patients with colon cancer, while pathological characteristics, adhesion pattern, and differentiation were significant for rectal cancer.

CONCLUSIONSMI is an adverse prognostic factor for patients with stage IIC CRC. T4 should be further classified according to the adhesion pattern.

Objective:To investigate the clinical characteristics of elderly patients with coronavirus disease 2019(COVID-19), in order to provide scientific evidence for the diagnosis and treatment of COVID-19 in elderly patients.Methods:Clinical data of 102 patients with COVID-19 admitted to the B11 East Ward of the Zhongfaxincheng campus and the E1-3 ward of the Guanggu Campus of Tongji Hospital affiliated to Huazhong University of Science and Technology in Wuhan from 1 February 2020 to 28 February 2020 were retrospectively collected and analyzed.Patients were categorized into 2 groups: the elderly group(≥60 years old)and the young and middle-aged group(<60 years old). Differences in epidemiological features, demographics, clinical symptoms, laboratory results and imaging findings between the two groups were retrospectively analyzed.Results:Among 102 patients with COVID-19, 58 were in the elderly group(≥60 years old), with a median age of 67.0(63.8, 71.0)years old, and 44 in the young and middle-aged group(<60 years old), with a median age of 47.5(38.0, 51.8)years old.There was no significant difference in gender ratio between the two groups( χ2=0.033, P=0.855). Of 102 patients, 42.0%(21/50)had close contact with an infected person, 14.0%(7/50)were from infection clusters, and 18.0%(9/50)had suspected hospital-acquired infections.Fever and cough remained the most common symptoms, but gastrointestinal symptoms such as nausea, poor appetite, diarrhea and muscle cramps were also warning signs.Fatigue and cough were the most common presenting symptoms in elderly male patients.Bilateral patchy infiltrates(57.9%, 22/38)and ground-glass opacities(42.1%, 16/38)were the main imaging features and 42.1%(16/38)patients had multiple areas of the lungs involved.Over 50% patients had increased levels of blood glucose, D-dimer, fibrinogen, C-reactive protein, procalcitonin, multiple cytokines and neutrophil-to-lymphocyte ratio, as well as decreased levels of albumin, hemoglobin, hematocrit, lymphocytes and serum calcium.Compared with the young and middle-aged group, the elderly group had higher rates of abnormality in levels of D-dimer and serum calcium( χ2=7.067 and 4.166, P=0.008 and 0.041). Conclusions:Fever and cough are the most common symptoms in elderly patients with COVID-19.Elderly patients with COVID-19 have multiple abnormalities in clinical laboratory test results, which show a certain level of specificity compared with young and middle-aged patients.

OBJECTIVETo evaluate curative effects of intramedullary nail and volar plate internal fixation for distal radius fractures.

METHODSThe studies concerning about randomized controlled trial of intramedullary nail and volar plate internal fixation for distal radius fractures from create database to May, 2016 were searched from PubMed, Cochrane Library, Web of Science, CNKI, Wan Fang data and VIP. Information was screen and taken out according to inclusion and exclusion criteria, quality of literature was evaluated according to Cochrane Handbook evaluating system. Meta analysis was performed by RevMan 5.2 software. Postoperative grip strength, clinical effects(results of flexion and extension, pronation, supination, deflection of ulnar and radialis) , imaging evaluation (ulnar variance, radial height, volar tilting angle and radial inclination) and the incidence of postoperative complications were analyzed.

RESULTSTotally 6 RCT including 370 patients were chosen. According to the Meta analysis, there were no statistical differences in extension[MD=5.63, 95%CI(-7.01, 18.27),=0.38], flexion[MD=3.10, 95%CI(-0.67, 6.86),=0.11], pronation[MD=2.58, 95%CI(-0.49, 5.65),=0.10], supination[MD=0.82, 95%CI(-1.89, 3.54),=0.55], radial deviation[MD=-5.16, 95%CI(-14.42, 4.11),=0.28], ulnar deviation[MD=0.19, 95%CI(-2.39, 2.77),=0.88], ulnar variance[MD=-0.01, 95%CI(-0.43, 0.42),=0.97], ulnar inclination[MD=-0.31, 95%CI(-1.37, 0.73),=0.56], radial height[MD=-0.27, 95%CI(-0.98, 0.44),=0.45], radial inclination[MD=0.29, 95%CI(-0.41, 0.99),=0.42] and the incidence of postoperative complications[RR=0.71, 95%CI(0.46, 1.09),=0.12] between intramedullary nail and volar plate internal fixation.

CONCLUSIONSCompared with volar plate internal fixation, intramedullary nail has the same effect in grip strength, clinical effect, but could not reduce the occurrence of postoperative complications. However, a large number of prospective randomized controlled study should be carried out to prove clinical effect of intramedullary nail for distal radius fractures.

OBJECTIVETo study the effect of chronic multiple stress on learning and memory, and the expression and activation of cerebral extracellular signal-regulated protein kinase (ERK) 1/2 of rats in vivo.

METHODSNinety male SD rats were divided randomly into control group and stress group. Rats in stress group were stressed everyday by one of the seven stressors including cold exposure, foot shock, white noise, restraint, tail hung up, sleep deprivation, and level shake, and then the ability of learning and memory was determined by Morris water maze test. Serum corticosterone (CORT) level was determined by radioimmunoassay kit. Western blot was performed to determine the expression and phosphorylation of ERK in hippocampus and prefrontal cortex of the brain.

RESULTSThe escape latencies of stressed rats were substantially longer than those of the controls in the water maze test (P < 0.01) except a transient recovery at the end of the third week after the stress. The stress also resulted in significantly higher serum CORT level and decreased P-ERK level in hippocampus and prefrontal cortex (PFC) (P < 0.01). Similarly, transient elevation of both CORT and P-ERK levels were observed at the end of the third week.

CONCLUSIONChronic multiple stress can lead to impaired learning and memory by decreasing the phosphorylation of ERK in the hippocampus and PFC. The partial recovery of learning and memory, CORT and P-ERK levels at the end of the third week may due to the adaptation of the rats to stressors.
