Objective To develop a practical image acquisition strategy using intermittent breath?hold cone beam computed tomography (CBCT). Methods A breathing phantom was used to simulate the movement of tumor near the diaphragm during free breathing and breath hold and scanned by conventional breath?hold CBCT and type Ⅰ/Ⅱ intermittent breath?hold CBCT. In the conventional breath?hold CBCT, scan paused and free breathing occurred at the break of breath hold and free breathing was not included in the scan. In the intermittent breath?hold CBCT, one scan covered several breath holds separated by free breathing in a ratio of 3 vs1. Image quality and three?dimensional registration accuracy were quantitatively compared between conventional breath?hold CBCT and type Ⅰ/Ⅱ intermittent breath?hold CBCT. Comparison of image quality parameters between conventional breath?hold CBCT and intermittent breath?hold CBCT was made by paired t test. Results Motion artifacts arose in type I and Ⅱ intermittent breath?hold CBCT scans. There were no significant differences in the reconstructed pixel value or uniformity between intermittent breath?hold CBCT and conventional breath?hold CBCT ( P>0. 05, and P= 0. 02, 0. 53 ) . Compared with conventional breath?hold CBCT images, the signal?to?noise ratios of type I andⅡintermittent breath?hold CBCT images were reduced by 30% and 60%, respectively ( P<0. 05 ) . The registration error was up to 0 . 4 cm in the anterior?posterior direction and less than 0 . 1 cm in other directions . Conclusions The phantom study shows that intermittent breath?hold CBCT does not significantly reduce image quality or registration accuracy compared with conventional breath?hold CBCT. The feasibility of intermittent breath?hold CBCT in clinical application needs to be further validated among a large number of patients.

Objective To explore the CT and MR imaging features of nodular fasciitis(NF), which will in return improve the standard and quality of diagnosis. Methods CT (n = 4) and MRI (n = 5) findings of pathologically proved nodular fasciitis in 9 patients were retrospectively analyzed. Results Of 9 NF, 5 were located in the lower extremities, 2 in the abdominal wall, and the others in the acoustic duct. The resected tumor size vary from 1.1 to 9. 5 cm in the largest diameter and mean (3.7±0.3) cm. All lesions appeared as a discrete solid mass on imaging. The CT value of lesions was similar to muscle. MR imaging manifested as a hypo to isointense lesion on T_1WI and hyperintense signal intensity on T_2WI. There was homogeneous or heterogeneous moderate to significant enhancement in the lesions. Conclusion CT and MRI can provide helpful information for the clinical and differential diagnosis of NF.

Objective To evaluate the clinical efficacy of universal self-locking anatomical plate for acetabulum and pelvis (USAPAP) in the treatment of posterior acetabular fractures.Methods Data of 55 patients with posterior acetabular fractures who were treated with the USAPAP from January 2014 to January 2016 were retrospectively analyzed.There were 39 males and 16 females with an average age of 38.5 years old (range,17-82 years).There were 35 fractures on the left side while the other 20 fractures were on the right side,including 52 fresh cases and 3 old cases.According to Letournel-Judet classification,there were 32 cases of posterior wall,9 cases of transverse and posterior wall,5 cases of anterior column and posterior wall,2 cases of posterior column,2 cases of transverse,2 cases of two columns,1 case of anterior column and posterior hemitransverse,2 cases of Pipkin type Ⅳ.All patients were managed operatively by the USAPAP,which allows simultaneous fixation for two columns and quadrilateral surface fractures through a single Kocher-Langenback approach.The quality of reduction was assessed by Matta's score system.The mean follow-up period was 18.5 months (range,12-24 months).Average operation time was 95 min,and average blood loss was 350 ml.Average operation time of plate and screws fixation was 19 min,and average fluoroscopy times in the surgery was 2 times.The mean time of bony union was 4.3 months.According to the criteria described by Matta,the excellent and good rate of radiological score was 92.7％ (51/55),including 39 cases excellent,12 cases good and 4 cases poor.The excellent and good rate of Merle d'Aubigne-Postel score was 87.3％ (48/55),including 35 cases of excellent,13 cases of good,5 cases of fair,and 2 cases of poor.Heterotopic ossification occurred in 1 patient (Brooker type Ⅱ) at three months postoperatively.One case with Pipkin type Ⅳ fracture underwent total hip arthroplasty due to femoral head necrosis at seven months postoperatively.Complications including wound infection,sciatic nerve injury,screw invade joint,redisplacement of the fracture,avascular necrosis of bone fragment,hardware failure,nonunion or malunion was not found in any case at the latest follow-up.Conclusion The USAPAP through the single posterior Kocher-Langenback approach provides strong and stable fixation for complex acetabular fractures associated with posterior region including posterior wall,both columns and quadrilateral surface.Satisfactory clinical results can be achieved by the use of this method.

The research on risk factors for stroke is of great significance for the early identification of high-risk groups and the improvement of prognosis. Studies have confirmed that insulin resistance （IR） is an independent risk factor for cerebrovascular diseases. Triglyceride-glucose （TyG） index has a great potential value as a simple and reliable alternative index for IR. A relatively high TyG index is associated with increases in atherosclerosis， carotid intima-media thickness， carotid plaque instability， and the incidence rate of cardiovascular diseases. A large number of evidence has proved that TyG index can predict the risk of ischemic stroke. TyG index is independently associated with the adverse clinical outcomes of ischemic stroke， which can aggravate the deterioration of the nervous system during hospitalization and cause the recurrence of ischemic stroke. Individuals with a high TyG index are more likely to develop cerebrovascular diseases， and a potential linear dose-response relationship is observed. This article systematically summarizes the evidence for the association between TyG index and stroke and discusses the value of TyG in optimizing the risk stratification of ischemic stroke.

Objective To investigate the demographic characteristics, clinical features, diagnosis and treatment of patients with gout in China.Methods Clinical data of 6 814 patients with gout from 100 hospitals in 27 provinces, municipalities or autonomous regions in China were collected and analyzed. Results (1)The ratio of male to female in patients with gout was 14.7:1.The mean age of onset was(48.8 ± 15.1)years old.Mean serum urate level was(526.7 ± 132.3)μmol/L.Patients'education background was of U-shaped distribution; (2) Hypertension was the most common comorbidity [15.8%(1 079/6 814)], then overweight or obesity[51.9%(3 536/6 814)];(3)Alcohol and high-purine food intake were dominant triggering factors in men. The diagnosis of gout was made after onset in majority of patients with cardinal symptom arthralgia.Most patients had the disease less than 5 years,and the longer the course,the more flares in the previous year of entry;(4)Febuxostat was the mostly used urate-lowering medication.20.7%(1 412/6 814), 10.8%(739/6 814) and 3.9%(265/6 814) of patients were followed up in 4 weeks, 12 weeks and 24 weeks after registration,and 18.9%(267/1 412),29.1%(215/739)and 38.1%(101/265)of them reached the control target of serum urate levels,respectively.After treatment,patients'liver function was not affected,but serum creatinine levels decreased significantly. Conclusions The proportion of gout patients who reach target serum urate level is very low.Further steps including education and survey need to be carried on.

Objective To compare the efficacy of operative and non-operative methods in the treatment of severe thoracic trauma in Tibetan Plateau.Methods A retrospective case-control study was conducted to analyze 286 patients with severe thoracic trauma admitted to the Shigatse People's Hospital from August 2016 to October 2018.There were 206 males and 80 females,aged 13-71 years [(34.3 ±11.6) years].The duration from injury to hospital ranged from 2 to 49 hours [(22.8 ± 8.3) hours].The causes of injury including fall from height in 109 patients,traffic injury in 98,crush injury in 32,blunt injury in 29,cattle head injury in 9,knife stab injury in 6 and other causes in 3.The injury severity score (ISS) varied from 16 to 48 points on admission [(24.2 ± 8.8) points].A total of 159 patients underwent operation (Operation group) and 127 patients underwent non-operative treatment (Non-operation group).The ISS score was (25.2 ± 8.3)points in Operation group and (23.7 ±7.9)points in Non-operation group.The length of hospital stay,intensive care unit (ICU) care time,complication rate and mortality were recorded in two groups.The correlation of ISS and age with mortality was investigated.Results The length of hospital stay was (12.2 ± 3.8) days in the Operation group and (19.7 ± 5.8) days in the Non-operation group (P ＜ 0.05).In the Operation group,27 patients were admitted to the ICU and stayed for (4.7 ± 1.3)days,and in the Non-operation group 33 patients were admitted to the ICU and stayed for (11.7 ± 3.2) days (P ＜ 0.05).The complication rate was 17.6％ in the Operation group and 31.5％ in the Non-operation group (P ＜0.05).Two patients died in the Operation group,with the mortality rate of 1.3％;six patients died in the Non-operation group,with the mortality rate of 4.7％,with no statistical difference (P ＞ 0.05).There were statistically significant differences in the age of death between the Operation group and the Non-operation group (P ＜ 0.05).The differences in the ISS score and age between the survival and death patients within the two groups were statistically significant (P ＜0.05).Logistic regression analysis showed age (OR =1.090,95％ CI 1.002-1.186) and ISS (OR =1.058,95％ CI 1.027-1.090) were slqnificantly related to mortality.Conclusions For severe thoracic trauma in Tibetan Plateau,operative treatment can shorten the length of hospital stay and ICU care time and reduce the incidence of complications.The mortality ratio of the two groups has no significant difference.Age and ISS may be the high risk factors for death of severe thoracic trauma patients.

Objective:To evaluate the visibility of intracranial deep medullary vein (DMV) by sensitivity weighted imaging (SWI), and explore its correlation with recent small subcortical infarct (RSSI).Methods:From March 2021 to May 2022, 277 patients with cerebral small vascular disease (CSVD) confirmed by cranial MRI in Department of Neurology, Third Hospital of Hebei Medical University, were consecutively enrolled. These patients were divided into RSSI group ( n=128) and non-RSSI group ( n=149) according to RSSI presence or not within one week of onset. According to the DMV scores, these patients were divided into mild-moderate DMV group (0-12 scores, n=199) and severe DMV group (13-18 scores, n=78). The clinical and imaging data of these groups were analyzed retrospectively and compared. Multivariate Logistic regression analysis was used to determine the correlation between DMV and RSSI, as well as the independent influencing factors for DMV grading. Results:The cerebral microbleed (CMB), periventricular white matter hyperintensity (WMH) scores, deep WMH scores, total WMH scores, total CSVD burden scores, and DMV scores in patients of the RSSI group were significantly higher than those in the non-RSSI group ( P<0.05); and patients in the RSSI group had significantly younger age and significantly lower high density lipoprotein cholesterol (HDL-C) level than those in the non-RSSI group ( P<0.05). Multivariate Logistic regression analysis showed that DMV score ( OR=1.142, 95%CI: 1.026-1.271, P=0.016) was an independent influencing factor for RSSI after adjusting for HDL-C and deep WMH scores. The severe DMV group had significantly older age, statistically higher percentages of patients having history of hypertension, CMB, lacuna and moderate to severe EPVS in basal ganglia, and significantly higher periventricular WMH scores, deep WMH scores, total WMH scores, and total CSVD burden scores as compared with the mild-moderate DMV group ( P<0.05). Multivariate Logistic regression analysis showed that age ( OR=1.101, 95%CI: 1.060-1.143, P<0.001) and total CSVD burden scores ( OR=3.589, 95%CI: 2.506-5.141, P<0.001) were independent influencing factors for DMV scores. Conclusion:DMV is involved in the mechanism of RSSI, and DMV visibility can be used as an indicator to diagnose RSSI and evaluate RSSI progression.

Objective:To investigate the change of the detection rate of colorectal cancer (CRC), colorectal adenoma and advanced adenoma in adults under colonoscopy in Shihezi in the past ten years.Methods:Data of patients who completed colonoscopy in the First Affiliated Hospital of Shihezi University School of Medicine from January 1, 2010 to December 31, 2019 were investigated. The medical records were collected by consulting the electronic medical record system, including the age and sex of patients and the location, quantity, size and pathological type of lesions. The detection rates, including the overall detection rate in the past 10 years, those in the first 5 years (from 2010 to 2014) and the second 5 years (from 2015 to 2019) of colorectal adenomas, advanced colorectal adenomas and CRC, were studied.Results:A total of 50 645 cases were included, 14 931 cases were excluded by the exclusion criteria, and finally a total of 35 714 cases were included in the data analysis. The 10-year overall detection rates of colorectal adenoma, advanced colorectal adenoma and CRC were 17.65% (6 302/35 714), 4.45% (1 589/35 714) and 3.71% (1 324/35 714), respectively. The overall detection rates of colorectal adenoma and advanced colorectal adenoma in the second 5 years were higher respectively than those in the first 5 years [20.33% (4 565/22 457) VS 13.10% (1 737/13 257), 4.69% (1 053/22 457) VS 4.04% (536/13 257)]. The overall detection rate of CRC in the second 5 years [3.30% (741/22 457)] was lower than that in the first 5 years [4.40% (583/13 257)].Conclusion:Compared with 2010 to 2014, the detection rate of colorectal adenoma in Shihezi area in 2015 to 2019 increased significantly, the detection rate of advanced colorectal adenoma increased slightly, and the detection rate of CRC decreased slightly. Therefore, the detection and resection of colorectal adenoma by colonoscopy may be important in reducing the incidence of CRC.

Objective:To analyze the intervention effect of rehabilitation platform-based online psycho-education on patients with bipolar disorder (BD) in remission stage.Methods:In this randomized controlled study, 91 patients with BD in remission stage who attended the community health center in Xicheng District, Beijing from July to August 2021 were randomly divided into a test group (46 cases) and a control group (45 cases) according to a 1∶1 ratio using the random number table. Baseline data were collected from both groups, and the control group received conventional medication and community telephone follow-up, while the test group was given online mental health education in the form of a WeChat subscription number on this basis, including BD mental health education course push (twice a week) and disease self-management (daily recording of mood, sleep, medication, exercise and gratitude diary), and the intervention period was 6 months in both groups. During the intervention, one patient in the test group was admitted to hospital due to exacerbation of mental illness and the trial was terminated. A total of 90 cases were included in the study. The scores of Medication Adherence Rating Scale (MARS), Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS) and Perceived Devaluation-Discrimination Scale (PDD) were assessed at baseline, after 3 months and 6 months of intervention in both groups, respectively. And the differences in baseline data between the two groups were compared using two independent samples t test and χ2 test, and the repeated-measures ANOVA was used to compare the differences in MARS, HAMD, YMRS, and PDD scores between the two groups before and after the intervention, and to analyze the intervention effects of network mental health education based on the rehabilitation platform on patients in remission stage of BD. Results:After 6 months of intervention, MARS scores in the test group was significantly higher than that in the control group [(8.47±1.75) vs (7.47±1.85)], and was significantly higher than that at baseline (7.36±2.13) and after 3 months of intervention (8.04±1.68) (all P<0.05). YMRS and PDD scores in the test group were significantly lower than those at baseline after 3 and 6 months of intervention [YMRS, 2.0(1.0,4.0),2.0(0,3.0) vs 3.0(1.0,5.5); PDD, (31.18±4.65), (30.13±4.76) vs (32.51±4.51)] (all P<0.05); the differences in YMRS and PDD scores in the control group were not statistically significant (all P>0.05). There was no statistically significant difference in HAMD scores between the two groups before and after the intervention (all P>0.05). Conclusion:Combining mental health education based on rehabilitation platform with conventional medication and community management can significantly improve the medication compliance of patients with BD in remission stage, and improve their manic symptoms and reduce the stigma of the disease.
