Objective To evaluate the curative effect of coenzyme complex and potassium magnesium aspartate on the restoration of rhythm and anti-arrhythmia in postoperative valve replacement patients for rheumatic heart disease.Methods Eight two patients with rheumatic heart disease were randomized into 2 groups,with no statistical significance in the patients' parameters.Treatment group A (n =41 )received i.v.coenzyme complex and potassium magnesium aspartate 30 ml during operation.Group B ( n =41 ) were only given potassium magnesium aspartate 30 ml.Other conventional therapies were the same for the two groups.At the same time,rate of spontaneous restoration of rhythm and severe arrhythmia incidences and low cardiac output syndrome were also recorded.Results The rate of spontaneous restoration of rhythm in the treatment group were higher than that in the control group ( 97.56％ vs 80.49％,x2 =6.12,P =0.01 ).There were significant differences in the severe ventricular tachycardia,ventricle fibrillation and auricular flutter events between the 2 groups ( 19.51％ vs 41.46％,x2 =4.67,P =0.03 ).The rate of low cardiac output in the treatment group were lower than that in the control group( 14.63％ vs 36.58％.x2 =5.18,P =0.02).To evaluate the effect of combination therapy on the spontaneous restoration of rhythm,Logistic regression analysis showed that OR( odds ratio) value was 9.69 and 95％ CI( confidence interval) was 1.15 - 81.55 ( P =0.03 ).Other variables affecting the spontaneous restoration of rhythm included the time of aortic obstruction( OR =9.28,95％ CI 1.21 - 78.18,P =0.02) and cardiac function before operation ( OR =4.95,95％ CI 1.27 - 17.88,P =0.02),operating time (OR=3.99,95％CI 1.18- 11.62,P =0.04),age(OR=2.77,95％CI1.11 -9.74,P=0.04).Conclusion Combined administration of coenzyme complex and potassium and magnesium aspartate in the operation of valve replacement in patients with rheumatic heart disease is able to promote the spontaneous heart rhythm restoration and reduce the chance of severe ventricular tachycardia and low cardiac output events.

Retmperitoneal ganglioneuroma is a rare neurogenic benign tumor.The prognosis of patients was good when the tumor was completely resected,while the surgical procedure is complicated.In March of 2013,a male patient with complex retroperitoneal ganglioneuroma was treated at the First Affiliated Hospital of Chongqing Medical University.A hypoechoic solid lesion (size,6.5 cm ×4.5 cm) adjacent to the head of the pancreas was detected by color Doppler ultra-sonography 9 months ago,and no any other clinical symptoms were detected.Perioperative abdominal computed tomography and the surgery confirmed that the tumor (size,8.5 cm × 7.5 cm × 4.5 cm) was located beneath the pancreas,encompassing thc ccliac artery,hepatic artery,splenic artery and superior mesenteric artery,surrounding the head and uncinate process of the pancreas,making it impossible to be separated.The tumor was closely connected with the portal vein,superior mesenteric vein,splenic vein and left renal vein.The tumor was separated from the major blood vessels,the body and tail of the pancreas,while the tumor could not be resected from the pancreatic head,and thus tumor resection and pancreaticoduodenectomy were performed.The surgery was extremely diffcult,but the complete removal of tumor was successfully achieved without excision of the major blood vessels and the patient recovered well.

Objective To develop the personalized 3D printing scaffolds for bone grafts,to meet the needs of the patients with the bone defect.Methods The model of three-dimensional woodpile structure was designed by the software of computer-aided design (CAD).The β-tricalcium phosphate (β-TCP),hydroxyapatite (HA),and polylactic acid (PLA) composite scaffolds with three-dimensional woodpile structure was simulated using 3D printing method by three-dimensional air floating platform.The three-dimensional bone graft scaffolds was then vacuum heat-treated,and the residual chloroform was detected by energy dispersive X-ray spectrometer.The morphology of the β-TCP/HMPLA scaffolds was characterized by scanning electron microscope,and in vitro cytotoxicity against osteoblasts hFOB 1.19 was assessed by thiazolyl blue tetrazolium bromide (MTT) assay.Results When the extrusion pressure of printing slurry was 137.9-413.7 kPa,the three-dimensional bone graft scaffolds could be printed out.Then the scaffolds was vacuum treated at 90 ℃ and preheated at 150 ℃,which could eliminate the solvent CHC13.The three-dimensional bone graft scaffolds,with a through-hole and rough surface,was co-cultured with osteoblasts hFOB1.19 for 7 d,and it's cytotoxicity grade was grade 0.Conclusions The three-dimensional bone graft scaffolds have a through-hole and rough surface,which is favorable to the osteoblasts culture and bone induction,indicating the advantage and development prospects of 3D printing in the preparation of porous materials for bone grafts.

Objective:To observe the clinical efficacy of electroacupuncture (EA) combined with tuina for chronic tension-type headache (CTTH). Methods:A total of 97 CTTH cases were randomly allocated into an observation group (n=52) and a control group (n=45). Patients in the observation group were treated with EA plus tuina based on pattern identification, whereas patients in the control group were treated with oral amitriptyline and oryzanol. Patients in both groups were treated for 8 weeks. A follow-up was conducted 3 months after the treatment. The intensity, duration, and frequency of the headache were recorded and compared before and after the treatment. Additionally, the patients' psychological state and quality of life (QOL) were compared between the two groups. Results:There were intra-group statistically significant differences in headache intensity score, headache duration, and headache frequency after the treatment and during the follow-up compared with those before the treatment (allP<0.05); and there were between-group statistically significant differences during the same time frame (allP<0.05). The Hamilton depression scale-17 items (HAMD-17) and Hamilton anxiety scale (HAMA) scores were significantly reduced in both groups after the treatment or during the follow-up (allP<0.01); and there were no between-group statistical significances during the same time frame (allP>0.05). The World Health Organization quality of life-BREF (WHOQOL-BREF) scores were significantly reduced in both groups after the treatment or during the follow-up (allP<0.05); and the scores in the observation group were significantly lower than those in the control group (allP<0.05) during the same time frame. The total effective rate was 88.0% in the observation group, versus 71.4% in the control group, showing a significant difference (P<0.05). Conclusion:EA combined with tuina can significantly decrease the frequency of chronic tension-type headache, alleviate headache intensity, shorten headache duration, and improve the patients' wellness. It is better than amitriptyline plus oryzanol.

Objective To investigate the impact of AG490 on the blood-brain barrier (BBB ) permeability and the expression of interleukin-6 (IL-6 )and tumor necrosis factor-α(TNF-α)after traumatic brain injury (TBI)in rats. Methods A total of 144 healthy male SD rats were randomly divided into a control group,a trauma group,and an AG490 intervention group (n=48 in each group). The rats in each group were redivided into four subgroups (4 h,1 d,3 d,and 7 d subgroups)according to the time points after cerebral injury (n=12 in each subgroup). A brain trauma models were induced by hydraulic shock method. Evans blue was used to determine the changes of the BBB permeability after cerebral injury in each group. Real-time fluorescence quantitative PCR was to detect the expression levels of TNF-αand IL-6 mRNA in rat brain tissue. Immunohistochemistry was used to detect the expression of human phospho tyrosine kinase (P-JAK2). Results (1)The permeability of BBB:The permeability of BBB increased at 4 h,1 d,3 d and 7 d after brain injury in the trauma group (Evans blue permeation:10. 4 ± 1. 2,16. 0 ± 1. 4,22. 3 ± 2. 0,and 8. 4 ± 0. 9μg/g,respectively). Compared with the control group, there were significant differences (all P<0. 01). The Evans blue permeation of the AG490 intervention group were 9. 1 ± 1. 0,12. 8 ± 1. 1,17. 5 ± 1. 4 and 7. 1 ± 0. 8μg/g,respectively at each time point,and they were all significantly lower than those of the trauma group (all P<0. 01). (2)The expression of IL-6 and TNF-α mRNA:The expression levels of IL-6 mRNA and TNF-α mRNA at 4 h,1 d,3 d and 7 d after traumatic brain injury in the trauma group were 2. 31 ± 0. 35,2. 73 ± 0. 35,3. 32 ± 0. 29,2. 14 ± 0. 24 and 7. 46 ± 1. 18,9. 42 ± 1. 54,13. 76 ± 1. 89,and 6. 28 ± 1. 00,respectively,they were all significantly higher than those of the control group (all P<0. 01). The expression levels of IL-6 mRNA and TNF-α mRNA of the AG490 intervention group were 1. 14 ± 0. 22,1. 54 ± 0. 23,1. 94 ± 0. 32,1. 26 ± 0. 21 and 5. 57 ± 0. 88, 7. 78 ± 1. 02,11. 51 ± 1. 29,and 5. 05 ± 0. 97,respectively,they were all lower than those of the trauma group,but they still higher than the control group. There were significant differences (all P<0. 01). (3 )The expression of P-JAK2:The expression levels of P-JAK2-positive cells at each time point after traumatic brain injury in the trauma group were significantly higher than the control group (all P<0. 01),they were 17. 4 ± 2. 7,56. 2 ± 6. 7,26. 1 ± 5. 4,and 15. 3 ± 2. 5,respectively;those of the AG490 intervention group were 12. 2 ± 1. 4,41. 5 ± 4. 6,19. 4 ± 4. 1,and 9. 6 ± 2. 0,respectively,they were all lower than those of the trauma group,but still higher than the control group. There were significant differences (all P<0. 01). Conclusion During the acute phase after TBI,AG490 may activate the factor signaling pathways by inhibiting the non-receptor tyrosine kinase/signal transduction and transcription,significantly inhibit the expression of brain tissue inflammatory cytokines IL-6 IL-6 and TNF-α,reduce the BBB damage,and help to reduce secondary brain injury.

Objective: The purpose of the current study was to determinate the prevalence of dating violence perpetration and victimization and to examine its relationship with childhood abuse among medical college students. Methods: Cluster sampling survey was carried out among 3 727 freshmen and sophomores in two medical colleges from Anhui Province. Information with general demographic variables, childhood abuse and dating violence was obtained. Logistic regression was used to identify the relationship of different types of childhood abuse and dating violence after controlled for confounding factors. Results: The rate of dating violence perpetration and victimization was 37.8% and 27.8%, respectively. Female students had higher childhood emotional abuse experience (61.9%) than male students (51.6%), while male students had higher childhood physical and sexual abuse (28.2% and 19.4%) than females (24.3% and 10.5%) (χ2=33.84，6.33，52.97，P<0.01). Results showed that increased dating violence perpetration [OR(95%CI)=1.71(1.48-1.98),1.55(1.33-1.82),1.75(1.43-2.15)]and victimization [OR(95%CI)=1.84(1.43-2.16),1.59(1.34-1.87),1.62(1.32-2.00)](P<0.01) among individuals with physical, emotional and sexual abuse after controlling for confounding variables. No gender difference was found within other groups in the relationship between childhood abuse and dating violence(P>0.05). Conclusion Childhood abuse experiences are associated with higher risk of dating violence perpetration and victimization among college students. Reducing childhood abuse is beneficial to the prevention and control of dating violence among medical college students.

Objective To classify and grade the environments with Oncomelania hupensis snails inside embankment in marsh-land and lake areas,so as to improve the work efficiency and realize the systematic management. Methods The schistosomiasis endemic area Liaodi and Xiongdi villages in Jiangling County,Hubei Province were selected as the experiment villages,and the environments with snails in the two villages were divided into sections with a length of 500m,then the snail situation were sur-veyed by the systematic sampling method with 10m and 50m a frame respectively. The environments were classified according to the discovery of infected snails and wild fecal contamination,and the numbers of sites with snails and their areas in different class-es were recorded. Meanwhile,the data of sites with infected snails in Jingzhou City during the recent 5 years were collected and graded according to the average density of snails,so as to discuss the correlativity between the grades of environments with snails and the numbers of sites with infected snails and the occurrence rate of frames with snails. Results There were 1 967 sites with in-fected snails in Jingzhou City during the recent 5 years,and there was a positive correlation between the grades of environments with snails and the occurrence rate of frames with snails(rs=0.77,P<0.01),when the grade was 5,the constituent ratio of num-bers of sites with infected snails was 3.1%,and when the grade was 2-3,the ratio raised to 56.3%. There were 39 sites with snails in the two villages,the Class 1,2 and 3 environments included 1,18 and 20 sites,with the areas of 1 080,51 640 m2 and 41 220 m2 , respectively. There were no statistically significant difference between the grades divided by snail survey with 10m and 50m a frame(χ2=4.667,P>0.05),but the time-consuming of the former was 3 times of the latter. Conclusions The classification and grading of the environments with snails inside embankment in marshland and lake areas can master the key point of the snail survey. The subsection and setting frames at a suitable distance can save time and manpower,improve work efficiency,as well as understand the distribution of snail status of the environment with snails,which can realize the sort management of the snail envi-ronments inside embankment.

Objective:To investigate the safety and utility of using polyester spacers in conventional pancreatico-enteric anastomosis in pancreaticoduodenectomy to achieve prevention of postoperative pancreatic fistula.Methods:The clinical data of 82 patients with pancreaticoduodenectomy completed by the same physician in Anyang People's Hospital from August 2018 to August 2023 were retrospectively analyzed, including 52 males and 30 females, aged (62.21±9.75) years. They were divided into two groups, test group ( n=40) and control group ( n=42) according to whether polyester spacers were used in pancreatico-intestinal anastomosis, the perioperative data of the two groups were compared, and Logistic analysis was used to analyze the risk factors affecting postoperative pancreatic fistula. Results:There was no statistically significant difference between the two groups in terms of biliary fistula, intestinal fistula, abdominal infection, abdominal bleeding, and postoperative mortality rate (all P>0.05). The incidence of postoperative pancreatic fistula in the test group was 20.0% (8/40) which was lower than that in the control group 45.2% (19/42), and the difference was statistically significant ( P=0.015). Soft pancreas texture ( OR=16.595, 95% CI: 1.891~145.657) was an independent risk factor for postoperative pancreatic fistula, while improved pancreatic enterostomy with polyester spacers ( OR=0.332, 95% CI: 0.114~0.969) could reduce the risk of postoperative pancreatic fistula. Conclusion:Use of polyester spacers to reinforce the pancreatico-enteric anastomosis during pancreaticoduodenectomy reduces the incidence of postoperative pancreatic fistulae with good safety and practicality.

Objective: The aim of this paper is to understand the associations between childhood abuse experience,parent-child relationship and non-suicidal self-injury (NSSI) in middle school students. Methods: Stratified cluster sampling method was used to select 14 500 middle school students from Shenzhen,Zhengzhou,Nanchang and Guiyang as participants. Questionnaire survey was conducted to collect information on childhood abuse exposure,parent-child relationship and NSSI. Results: The prevalence of NSSI was 14.81%,while it was higher among male students (15.95%) than female students (13.64%) (χ2=15.29,P<0.01). A multivariate Logistic regression models showed that the moderate and high level of childhood abuse (OR=2.23,3.27) and the low level of parents-child relationship (OR=1.80,1.36) were associated with high NSSI detection rate among middle school students (P<0.01). In each group of childhood abuse,low level of father-child relationship was associated with high NSSI detection rate among middle school students (OR=1.36,1.34,1.56,P<0.05). In the group with high level of childhood abuse experience,low level of mother-child relationship was associated with high NSSI detection rate (OR=1.20,P<0.05). Among male students,those with high level of childhood abuse experience,low level of parentchild relationship were associated with high NSSI detection rate (OR=1.46,1.35,P<0.01); regardless of the level of childhood abuse experience,low level of father-daughter relationship was associated with NSSI detection rate (OR=1.64,1.54,1.68,P<0.01) among females. Conclusion Childhood abuse experience and poor parent-child relationship are associated with NSSI in middle school students, with distinct gender difference. Prevention of childhood abuse and the improvement of parent-child relationship are beneficial to the prevention and control of NSSI.
