Objective To improve early diagnosis of testicular torsion,reduce misdiagnosis and reduce the rate of orchiectomy.Methods The diagnosis and treatment of testicular torsion in 31 cases were retrospectively ana-lyzed.Results 54.8% misdiagnosis rate was in this group,all the 31 cases were diagnosed by color Doppler ultra-sound,including 19 cases of retained testicle and orchiectomy in 12 cases (38.7%).In 19 cases of this group retained testis,testicular torsion time within 5 hours was 2 cases,and postoperative had testicles survival.In the 6 cases of testicular torsion time within 5 hours to 10 hours,5 cases had the testis survival.In the 5 cases of torsion of testis time was 10 hours to 24 hours,3 caseshad the testis survival.In the 6 cases of testicular torsion time more than 24 hours,2 cases of testis survival.After postoperative following-up,19 cases of retained testis had no recurrence,all the 31 cases were found no contralateral testicular torsion and all cases sex hormone levels were in the normal levels. Conclusion Testicular torsion is easily misdiagnosed,color doppler ultrasound should be preferred.Early diagnosis and aggressive surgical exploration,unity and strictly control the orchiectomy surgery indications,means a lot to reduce the rate of orchiectomy.

Objective To observe the clinical therapeutic effect of hyperbaric oxygen (HBO) therapy and swallowing training combined with Fengchi acupoint acupuncture on dysphagia caused by pseudobulbar paralysis after stroke. Methods Seventy-five patients were randomly divided into control group, HBO therapy group, swallow training group, acupuncture group and combined treatment group (n = 15). Patients in all groups were given cerebro-vascular disease routine treatment. In addition, the patients in HBO therapy group, swallowing training group and ac-upuncture group were given HBO therapy, swallowing training and Fengehi (GB20) acupoint acupuncture simultane-ously, respectively. The patients in combined treatment group were given HBO therapy combined with swallowing training and Fengchi acupoint acupuncture. Modified Kubota-Chiari's swallowing functional classification was used to assess swallowing function before and on the 3rd d,6th d,9th d, 12th d, 15th d, 18th d and 21st d after treatment. Results It was shown that the patients in all groups but the control group got significant improvement in swallowing after treatment, as demonstrated by the swallowing function scores (P < 0.05). Moreover, the priority order in im-provement of swallowing function and recovering rate were: combined treatment group > acupuncture group > swal-low training group > HBO therapy group > control group(P < 0.05). Conclusion The combination of HBO ther-apy, swallowing training and Fengchi acupoint acupuncture could act synergically to ameliorate dysphagia caused by pseudobulbar paralysis after stroke.

Objective To observe the effect of hyperbaric oxygen,rehabilitation training or acupuncture at Fengchi acupoint on pseudobulbar paralysis after stroke.Methods 90 patients were divided into group Ⅰ(A,B,C) or Ⅱ(A,B,C) randomly.Patients in all groups were given conventional therapy,while those in groups ⅠB and ⅡB were given hyperbaric oxygen,ⅠC and ⅡC were given swallowing training and group Ⅱ was given acupuncture at Fengchi acupoint additionally.They were assessed with Modified Kubota-Chiari's swallowing functional classification before and after treatment.Results In all groups except ⅠA,swallowing function scores improved after treatment significantly(P<0.05).The scores were different significantly between group Ⅰ and group Ⅱ after treatment(P<0.05).Except 3 d after treatment,the scores were different significantly between sub-group of group Ⅰ or group Ⅱon other time points(P<0.05).Conclusion The hyperbaric oxygen is more effective than conventional therapy on pseudobulbar paralysis,but less than swallowing training.Acupuncture at Fengchi acupoint can improve their efficacy.

Aggressive fibromatosis(AF)is a rare soft tissue tumor clinically that presents with local aggressive growth, are prone to relapse, but rarely metastasize to distant sites. It occurs in the limbs, trunk, mesentery, etc., but is rare in the pelvis or around the urinary system. This article reported a case of ureteral stenosis secondary to pelvic AF. The surgical treatment was effective.

Objective: To explore the characteristics of psychological control of parents of college students and their correlation with health risk behaviors, and to provide a reference for further improving parenting styles and improving the physical and mental health of college students. Methods: With the method of multi-stage stratified random sampling, 3 318 college students from 6 universities in Guizhou Province were selected. The parents’ psychological control questionnaire and Chinese adolescent health-related behavior questionnaire were used to conduct anonymous field survey. Results: A total of 660 students’ parents have got low score of mental control in low-score group (<26), 1 844 in the middle group (26-49) and 814 in the high group (>49). Students who had suicide plans scored higher in the dimensions of invasion of privacy, inhibition of speech expression, and sense of disability than those who had not(t=4.08, 3.74, 3.82, P<0.01); The scores of smokers in achievement expectation, invasion of privacy and ability ineffectiveness were higher than those of non-smokers(t=7.12, 3.91, 8.10, P<0.01); the scores of drinkers in all dimensions were higher than those of non drinkers(t=9.35, 4.64, 5.90, 8.78, P<0.01); the scores of Internet addicts in all dimensions were higher than those of non-smokers(t=8.92, 14.27, 3.70, 15.94, P<0.01). Spearman correlation analysis showed that smoking, drinking and Internet addiction were positively correlated with parents’ psychological control(r=0.11, 0.15, 0.19, P<0.01). Conclusion Parents’ psychological control of college students in achievement expectation, ability ineffectiveness and speech inhibition; parents’ psychological control is positively related to smoking, drinking and Internet addiction behavior. Parents should give more active encouragement and guidance to their children and strengthen communication.

Objective: To understand the smoking of college students in Guizhou Province and to explore associated factors for better prevention and control of smoking behavior. Methods: A multi-stage stratified random sampling method was used to describe the current smoking situation of college students. And 2 451 college students of different majors and grades from three cities with high, medium and low economic development levels were selected. Besides, we used multivariate logistic regression analysis to analyze the major factors affecting current smoking. Results: Ever smoking rate of college students in Guizhou Province was 50.8%, the peak age of first smoking attempt was 8-13(35.2%); current smoking rate of college students in Guizhou Province was 20.8%. Logistic regression analysis showed that male, upper grade, monthly living expenses of not less than 1 000 yuan, single parents, family smoking and peer smoking were the main risk factors affecting college students’ smoking(OR=5.52,1.44,1.48,1.69,1.47,1.88,P<0.05). Conclusion College students in Guizhou Province have a higher rate of smoking attempt and low rate of current smoking, as well as low tobacco dependence which is determined by multiple factors. Tobacco hazard education, mental health education and living environment intervention for college students may help reduce the probabitity for tobacco use.

Objective:To investigate the predictors of the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi, and to evaluate the predictive value of the maximum ureteral wall thickness (UWT) in the treatment of ureteral calculi with ESWL.Methods:The clinical data of 138 patients with ureteral calculi treated with ESWL in the Second People's Hospital of Hefei from January 2020 to December 2020 were retrospectively analyzed. There were 91 males and 47 females. The age was (50.9±14.8) years old. The body mass index was (25.3±3.6) kg/m 2. The stones of 73 cases were located on the left side and 65 cases were on the right side. 70 cases had upper ureteral stones, 18 cases had middle ureteral stones, and 50 cases had lower ureteral stones. The median length of the stone was 8.5 (7.5, 10.5) mm. The CT value of the stone was 509 (343, 783) HU. The anteroposterior diameter of the renal pelvis was 12.0 (10.1, 16.0) mm, and UWT was (2.8 ± 0.8) mm. All patients underwent urinary non-contrast CT before lithotripsy, and the UWT of the stone bed was measured on the CT images. According to the stone removal situation 2 weeks after the operation, the patients were divided into a successful lithotripsy group and a failed lithotripsy group. Univariate analysis was used to compare the differences of various indicators between the two groups, and multivariate logistic regression was used to analyze the independent predictors of ESWL in the treatment of ureteral calculi for the indicators. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) of each independent predictor, and the cut-off value, sensitivity and specificity were analyzed. Results:All operations were successfully completed, and the success rate of the first-stage lithotripsy was 71.7% (99/138). The results of univariate analysis showed that the stone length diameter, stone CT value, anteroposterior diameter of renal pelvis, stone skin distance, and UWT were significantly different between the successful lithotripsy group and the failure group ( P<0.05). There was no significant difference in age, gender, body mass index, stone side and stone location ( P>0.05). The results of multivariate logistic analysis showed that stone length ( OR=1.393, P=0.015), stone CT value ( OR=1.002, P=0.043) and UWT ( OR=17.997, P<0.001) were all for the efficacy of ESWL in the treatment of ureteral stones. The ROC curve was used to compare the three independent predictors. The area under the UWT curve was the largest (AUC=0.898, P<0.001), followed by the length of the stone (AUC=0.744, P<0.001), and the CT value of the stone (AUC=0.672, P= 0.002). The cut-off value for UWT was 3.19 mm, which had a sensitivity of 91.9% and a specificity of 71.8% for predicting the success of ESWL lithotripsy. When dividing the patients into thin wall group (UWT ≤3.19 mm) and thick wall group (UWT>3.19 mm) according to the cut-off value, the success rates of one-stage lithotripsy in the two groups were 89.2% (91 / 102) and 22.2% (8/36), respectively ( P<0.05). Conclusions:UWT, calculus length and calculus CT value are independent predictors of the efficacy of ESWL in the treatment of ureteral calculi, and UWT has the best predictive value. When UWT≤3.19 mm, the success rate of ESWL in the treatment of ureteral calculi is higher.

【Objective】 To evaluate the appropriate optimal capacity and matching probability of the platelet donor database with known HLA/HPA genotype in Shaanxi aera, and provide data support for subsequent construction, maintenance and application of the local platelet donor database. 【Methods】 A total of 11 755 individuals from the Shaanxi Branch of China Marrow Donor Program, 401 and 249 unrelated random platelet donors in Shaanxi aera were enrolled to the population study of HLA-A, -B polymorphisms, HPA genotyping and CD36 antigen expression, respectively. The frequencies of HLA-A, -B alleles, HPA alleles and haplotypes were calculated with Arlequin 3. 5. 2. 2 software; matching probability and capacity evaluation of platelet donor database was conducted according to the phenotypic frequencies. 【Results】 The population genetic and phenotypic polymorphisms data of HLA-A, -B and HPA1-6, 10, 15, 21 in Shaanxi aera were obtained. The frequency of CD36 type Ⅰ or Ⅱ deficiency was 0.40%(1/249). According to the subsequent calculating and deriving, with a database size of 194 donors, the patient having approximate 95% probability could achieve matching of HPA1-6, 10, 15, 21 genotype. With a database size of 1500 donors, there is a 95% probability of matching at least one donor with HLA-A-B phenotype frequency >0.002 or haplotype frequency >0.001; meanwhile, the probability of matching a cross-reactive group donor should be 44.95%-97.57%. Based on database size of 8 856 and 15 033, the probabilities of matching HLA-A, -B phenotype were about 80% and 90%, respectively. 【Conclusion】 The differences in the distribution of HLA/HPA polymorphism in different regions make the establishment mode and optimal capacity of platelet donor database different. It is necessary to apply a variety of platelet matching transfusion strategies to expand the range of donor selection, thereby effectively reducing the database construction cost and resource requirements.

【Objective】 To explore the association of HLAII(-DRB1, -DQB1, -DPB1) alleles and haplotypes polymorphisms with acute myeloid leukemia (AML) in northern Han population. 【Methods】 A total of 308 AML (non-M3) patients (patient group) and 824 unrelated healthy bone marrow donors (control group) were genotyped at a high-resolution level using polymerase chain reaction-sequence-based typing (PCR-SBT), next-generation sequencing (NGS) with Ion Torrent S5 platform and sequence specific oligonueleotide probes (SSO) with LABScan^® 3D platform. Frequencies of HLA II alleles and haplotypes were calculated with Arlequin 3.5.2.2 software. The odds ratio (OR) of AML was also calculated for case-control study. 【Results】 By χ² test and correction, an increased frequency of HLA-DRB1^*07∶01(14.61% vs 9.53%, P<0.01), HLA-DQB1^*02∶02(12.82% vs 8.31%, P<0.01), HLA-DQB1^*06∶02(11.53% vs 8.74%, P<0.05) and HLA-DPB1^*17∶01(5.84% vs 3.16%, P<0.01) among AML patients was discovered in significant comparison with the control group. After Bonferroni correction, the frequency of HLA-DRB1^*07∶01(Pc<0.05), HLA-DQB1^*02: 02(Pc<0.05) and HLA-DPB1^*17∶01(Pc<0.05) in AML patients were still higher than those in the control group, which had a strong positive correlation with AML (OR=1.62 (95% CI=1.23~2.14), 1.62(95% CI=1.21~2.18) and 1.91(95% CI=1.23~2.94), respectively. The frequency of two loci haplotype HLA-DRB1^*07∶01-DQB1^*02∶02 in AML patients was still higher than that of the control group after Bonferroni correction (12.66% vs 8.19%, Pc<0.05). The frequency of the 3 loci haplotype HLA-DRB1^*07∶01-DQB1^*02∶02-DPB1^*17∶01, as a susceptible haplotype of AML, was higher than that of the control group and was strongly correlated with AML. 【Conclusion】 The data on the association of HLA II (-DRB1, -DQB1, -DPB1) alleles and haplotype polymorphisms with AML in northern Han populations was obtained in this study. HLA-DRB1^*07∶01, HLA-DQB1^*02∶02, HLA-DPB1^*17∶01 and the HLA-DRB1^*07∶01-DQB1^*02∶02-DPB1^*17∶01 haplotype are the risk genes and susceptible extended haplotype for AML. The risk prediction based on HLA haplotype might be more accurate than that based on single allele.
