Objective To explore the therapeutic effect of choledochojejunostomy with a subcutaneous blind loop of interposed jejunum for treating postoperative residual biliary stones.Methods The clinical data of 72 cases of choledochojejunostomy with subcutataneous blind loop of interposed jejunum were retrospectively analysed.Results After exploration of distal common bole duct,and when a No.8-10 bougie could pass through the sphincter of Oddi,a 10-15 cm segment of jejunum with its vascular pedicle was mobilized,and an end to-side choledochojejunal anastomosis was performed at the proximal side of the jejunal segment and its distal end was converted to a blind loop and fixed subcutaneously to relevant abdominal wall.A T-tube for external drainage was inserted across the choledochojejunal anastomosis and exited through the blind jejunal loop.Seventy-two patients were cured without any complication or mortality.Conclusions The procedure is simple and minimally invasive,so that it could be carried out very easily and quickly by general surgeons with basic choledochojejunostomy skill.

OBJECTIVE: To analyze the epidemiological characteristics and treatment situation of pelvic fractures in 5 cities in Hunan, improve the treatment and provide epidemiological data for policymakers. METHODS: The clinical data of 65 patients with pelvic fractures were collected from 9 third-tier hospitals in Hunan from October 2012 to March 2013. The gender, age, cause, volume of blood transfusion, and prognosis were analyzed with SPSS 13.0. RESULTS: There were 44 male and 21 female patients (2.10:1.00). The age ranged from11 to 86 years and 74.6% of the patients were between 20 and 59. The main cause was traffic injury (30 cases, 46.2%) and fall injury (22 cases, 33.8%). About 73.8% patients suffered associated injuries all over the body. By Tile's classification of pelvic fractures, the average blood transfusion of type A was 483.33 mL, that of type B was 1 026.92 mL and type C was 1 905.56 mL. Compared with type A, the treatment outcome of type C patients was worse. CONCLUSION Pelvic fractures are mostly caused in young and middle-aged males by high-energy. Tile C pelvic fractures need more blood transfusion and have poor prognosis. Patients had better be taken straight to municipal hospitals by expertise. Safety education for high-risk groups should be enhanced to reduce the incidence of pelvic fractures.

Objective To investigate the expression of ki-67 and the development of the intimal hyperplasia(IH) of the irradiated human umbilical artery incorperated with nofloxacin and silver(IHUAINS) grafts into the carotid arteries of the rabbit. Methods Twenty IHUAINSs were sterilely produced. Thirty rabbit were performed bilateral carotid bypass grafting. The IHUAINS(experimental group)and the left carotid arteries (control group) were implanted in the left and right carotid arteries respectively. Graft patency was checked at the 2nd and 6th week after implantation, and the grafts were studied with standard histological techniques and immunohistochemieal method for meas-urement of intimal thickness and the expression of ki-67. Results The total patency rate of the grafts was 89.6%. Light microscopic exami-nation of the grafts revealed intimal and media proliferation, cellular in-filtration. The endothelial cells covered the vascular lumen. There was no significant difference of the intimal thickness between two groups at the 2nd week after grafting (P>0.05). The intimal thickness of the experimental group was larger than that in control group at the 6th week after implantation without statistical significance (P>0.05). At the same time, immunocytochemical analysis showed that the expression of ki-67 in the experimental group was stronger than that in control group without statistical significance(P>0.05). Conclusion The IH of the IHUAINS was larger than that of the autologous artery, but there is no difference between these two groups. Thus, IHUAINS may be an ideal graft in the field of coronary surgery.

ObjectiveTo improve the long term outcomes of the surgery for Stafford type A aorticdissection, we performed ascending aorta and total aortic arch replacement combined with transaorticstented graft implantation into the descending aorta for acute type A aortic dissection.MethodsFrom May 2005 to February 2011,36 consecutive patients with acute Stanford type A aorticdissection underwent this procedure.Right axillary artery cannulation was routinely used forcardiopulmonary bypass and selected cerebral perfusion.The stented elephant trunk was implanted through the aortic arch under hypothermic circulatory arrest.The stented elephant trunk was a 10 cm long selfexpandable graft.34 patients were followed up for 2 ～36 months.ResultsCardiopulmonary bypass time was (160 ± 31)min, average cross clamp time was (101 ±26)min, and average selective cerebral perfusion and lower body arrest time was (31 ± 16)min.The in-hospital mortality was 5.5％ (2/36).One patient died of multi-organ failure postoperatively and another died of cerebral infarction 9 day after surgery.No one suffered from spinal cord injury perioperatively.There was no late death during follow up.ConclusionsAscendingaorta and total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta is an effective way in closing the residual false lumen of the descending aorta and might contribute to better long term outcomes of type A aortic dissection.

Objective To explore the application effect of web-based model of Just-in-Time-Teaching (JiTT) in nursing courses in higher vocational education.Methods A total of 362 nursing students enrolled in 2014 to Nanyang Medical College were selected as the observation group, and the 397 nursing students enrolled in 2013 as the control group. In the course of Fundamental Nursing, offered in the first semester in the second year, students in the control group were taught with traditional teaching method, while those in the experimental group with model JiTT. Performance of the students between the two groups was compared in terms of theoretical exam and skill evaluation, and their autonomous learning ability.Results In the course Fundamental Nursing, scores of theoretical exam (85.66±3.23), skill evaluation (88.43±3.92), and total scores of autonomous learning (101.47±9.33) in the observation group were all higher than those in the control group (t=5.574, 5.626, 5.427;P<0.01).Conclusions The model JiTT can improve autonomous learning ability and teaching efficiency, which makes it a positive reference for use of modern information technology in nursing courses in higher vocational education.

The aim of this study was to investigate the expression of circulating microRNAs (miRNAs) in apolipoprotein E (apoE) knockout mice (apoE-/-) and to validate the role of these miRNAs in human coronary artery disease (CAD). Pooled plasma from 10 apoE-/- mice and 10 healthy C57BL/6 (B6) mice was used to perform the microarray analysis. The results showed that miR-34a, miR-21, miR-23a, miR-30a and miR-106b were differentially expressed in apoE-/- mice, and these expression changes were confirmed by real-time quantitative reverse-transcription PCR. Then, miR-34a, miR-21, miR-23a, miR-30a and miR-106b were detected in the plasma of 32 patients with CAD and of 20 healthy controls. Only miR-34a, miR-21 and miR-23a were significantly differentially expressed in the plasma of CAD patients (all P<0.01). In conclusion, miR-34a, miR-21 and miR-23a were elevated in CAD patients, which means that these miRNAs might serve as biomarkers of CAD development and progression.

Objective:To investigate the self-measured health status of college students in Tibet, and to construct the self-measured health scale (SRHMS V1.0) norm of College students in Tibet.Methods:This was a cross-sectional study. A multistage stratified sampling method was used. From April to June 2022, a total of 7 990 college students were selected from all colleges and universities in the Tibet Autonomous Region (7 in total). The self-rated health of Tibetan college students was investigated and evaluated by combining demographic information and SRHMS V1.0. Descriptive statistics, t-test, analysis of variance ( Brown-Forsythe test for unequal variance, LSD test for multiple comparisons), and Spearman correlation analysis were used to construct mean norm, percentile norm, and delimitation norm of physiological scale health (PSH), mental scale health (MSH), social scale health (SSH) score and total scale health (TSH) scores. Results:The total score of self-assessed health assessment among college students in Tibetan universities was (72.18±12.35). For different genders, the PSH, MSH, SSH and TSH scores were (73.85±13.78), (65.80±14.73), (69.85±16.00) and (73.44±12.77) for boys and (71.18±13.36), (62.81±14.03), (68.57±14.90) and (70.92±11.94) for girls, respectively. Scores on each subscale and total scale were statistically significant different between the different sexes ( t=2.531, 2.672, 1.867, 2.623, all P<0.05). For different grades, the PSH, MSH, SSH and TSH scores of the freshman were (73.36±13.23), (65.77±14.58), (70.98±15.60) and (73.51±11.91); the sophomore were (70.74±13.73), (62.40±13.60), (66.92±14.62) and (70.16±12.28), the junior were (75.48±13.09), (64.08±15.12), (71.90±15.12) and (74.10±12.36); and the senior were (67.21±14.41), (59.19±17.67), (64.91±18.59) and (66.94±14.59) respectively, with the differences in scores of each subscale and the total scale in different grades being statistically significant ( F=3.952, 3.611, 4.841, 5.583, all P<0.05). The mean norm, percentile norm and demarcation norm of the total score and each subscale of self-measured health of college students in Tibetan universities were constructed with gender and grade as the cut-off values. Conclusion:The model of self-measured health assessment scale for students in colleges and universities in Tibet is established, which can provide evaluation criteria for evaluating the health status of college students in Tibet and plateau areas.

Objective:To investigate the short-term efficacy of rotational femoral neck osteotomy with preservation of the round ligament in the treatment of subchondral insufficiency fracture of the femoral head (SIFFH) in young and middle-aged people.Methods:A retrospective case series study was used to analyze the clinical data of 13 patients with SIFFH, who were admitted to 920th Hospital of Joint Logistics Support Force from January 2017 to January 2022. The patients included 10 males and 3 females, aged 22-49 years [(33.5±8.3)years]. There were 6 patients with fracture on the left hip and 7 on the right hip. All the patients were treated by rotational femoral neck osteotomy with preservation of the round ligament. Postoperatively, standardized joint functional training was given. The operative time and intraoperative bleeding were recorded. The modified Harris hip score and visual analogue score (VAS) were compared preoperatively, at 3, 6 months postoperatively and at the final follow-up. Radiological examinations were used to observe the occurrence of any collapse of the femoral head, non-union at osteotomy site or other complications.Results:The patients were followed up for 13-24 months [(17.9±3.1)months]. The operative time was (127.3±9.8)minutes, with the intraoperative bleeding of (393.9±21.9)ml. The values of modified Harris hip score were (61.6±3.3)points, (80.2±4.4)points, and (91.9±4.1)points at 3, 6 months postoperatively and at the final follow-up, respectively, being significantly higher than the preoperative (51.4±3.5)points (all P<0.05), and there were significant differences between different postoperative timepoints (all P<0.05). The values of VAS were (4.9±1.1)points, (3.0±0.9)points, and (1.4±0.5)points at 3, 6 months postoperatively and at the final follow-up, respectively, being significantly lower than preoperative (6.7±0.9)points (all P<0.05), and there were significant differences between different postoperative timepoints (all P<0.05). Imaging examination showed no femoral head collapse, with all the bones healed at the osteotomy site. There were no serious complications such as bone non-union, incision infection or peripheral nerve injury. Conclusion:Rotational femoral neck osteotomy with preservation of the round ligament in treating SIFFH in the young and middle-aged population has the advantages of shortened operative time, less intraoperative bleeding, promoted hip function recovery, attenuated pain and decreased complications, showing a satisfactory early effect.

Pelvic floor muscle training (PFMT) is the first-line intervention for non-surgical treatment of female patients with stress urinary incontinence (SUI). However, due to the particularity of the physiological position of the pelvic floor muscles, 13% to 53% of patients are unable to perform PFMT correctly after the initial visit. In view of this, scholars at China and abroad put forward some other sports rehabilitation methods and achieve good clinical results. In this paper, exercise rehabilitation methods for female SUI patients were reviewed, including PFMT, core muscle training, Pilates, yoga, physical activities, etc., in order to provide reference for medical personnel to formulate scientific and feasible exercise rehabilitation programs for female SUI patients.
