Objective To investigate the expression,synergistic relationship and clinical significance of alcohol de-hydrogenase(ADH1A)and vascular endothelial growth factor-A(VEGFA)in hepatocellular carcinoma(HCC).Methods The expression and correlation of ADH1A and VEGFA in HCC and adjacent normal tissues were ana-lyzed by GEPIA.TCGA and GSEA were used to analyze the pathway of ADH1A in HCC.The clinical and patho-logical data of 84 patients with HCC were collected,and 54 patients with paracancer normal tissue samples were se-lected as controls to analyze the correlation between ADH1A and VEGFA and clinicopathological parameters of HCC.Immunohistochemistry was used to detect the protein expression of ADH1A and VEGFA in cases and con-trols,and the correlation between the expression of ADH1A and VEGFA and the clinical progression and prognosis of patients with HCC was analyzed based on clinical pathological parameters and Kaplan-Meier.Results Bioinfor-matics analysis found that ADH1A was low-expressed in HCC and VEGFA was highly expressed in HCC,and there was a negative correlation between the two(P<0.001);immunohistochemical detection results showed that the expression of ADH1A in HCC tissue was lower than that in normal tissue adjacent to cancer(P<0.01)while the expression rate of VEGFA in HCC tissue was significantly higher than that of normal tissue adjacent to cancer(P<0.01);The recurrence rate of vascular thrombus and HCC patients in HCC group with high expression of ADH1A was lower(P<0.05).The proportion of tumor diameter>5 cm,high TNM stage,microsatellite and G2-G3 dif-ferentiation in HCC tissues in VEGFA high expression group was higher(P<0.05).Kaplan-Meier survival analy-sis showed that patients with high ADH1A expression and low VEGFA expression had a higher five-year survival rate.Conclusion Low expression of ADH1A and high expression of VEGFA in tumor tissues of patients with HCC indicate tumor progression and can be used as one of the prognostic evaluation indicators for patients with HCC.

Objective To investigate the effect of respiratory training based on core stability training on feedforward control in pa-tients with chronic nonspecific low back pain(CNLBP). Methods A total of 60 patients with CNLBP in Jiaxing Second Hospital from January,2022 to March,2023 were ran-domly divided into control group(n=30)and experimental group(n=30).Both groups received health educa-tion,physical factor therapy and core stability training,while the experimental group received respiratory training in addition,for four weeks.Visual Analogue Scale(VAS)score,Japanese Orthopaedic Association low back pain(JOA)score and Oswestry Dysfunction Index(ODI)were compared between two groups before and after treat-ment,while surface electromyography was used to detect the root mean square(RMS)and integrated electromy-ography(iEMG)of transversus abdominis,multifidus and triceps(movement muscles),and the activation se-quence and relative activation time of transversus abdominis,multifidus and triceps were calculated. Results After treatment,the scores of VAS,JOA and ODI improved significantly in both groups(|t|>8.515,P<0.001),and the scores were better in the experimental group than in the control group(|t|>2.089,P<0.05).RMS and iEMG of transversus abdominis and multifidus improved significantly after treatment in both groups(|t|>18.831,P<0.001),and were significantly better in the experimental group(|t|>3.481,P<0.05).The transversus abdominis and multifidus in both groups were activated before the movement muscles,and the relative activation time of transversus abdominis and multifidus increased in negative(|t|>48.115,P<0.001),the experimental group being better(|t|>3.229,P<0.05). Conclusion Combination of core stability training and respiratory training is beneficial in reducing the pain of patients with CNLBP,reducing the lumbar dysfunction,improving the order of muscle activation,and strengthening feed-forward control.

Objective:To explore any effect of blood flow restriction during exercise on knee proprioception and motor coordination after anterior cruciate ligament (ACL) reconstruction.Methods:Thirty patients recovering from ACL reconstruction were randomly divided into an experimental group and a control group, each of 15. Both groups were given routine rehabilitation training, while the experimental group was additionally provided with 45 minutes of training with blood flow restriction, 3 times a week for 8 weeks. The blood flow restriction training involved constant pressure in the groin while the patient performed knee flexion and extension resistance training, squats, alternate knee flexion and extension and ergometer cycling. Before and after the intervention, both groups′ knee function, proprioception and lower limb motor coordination were evaluated using the Lysholm knee scale, the Humac isokinetic measurement system and surface electromyography.Results:Before the experiment there were no significant differences between the two groups in any of the measurements. After the intervention, both groups′ average Lysholm score had improved significantly, and errors in reproducing a knee angle had decreased significantly. Significantly better improvement was observed in the observation group than in the control group. That group′s average coordinated contraction rate on the affected side in extension and flexion was also significantly better than the control group′s ave-rage. Indeed, there were no significant differences in the contraction rates between the healthy and affected sides.Conclusions:Training with restricted blood flow can significantly improve knee function, proprioception and motor coordination after anterior cruciate ligament reconstruction.

Objective:To explore the effect of blood flow restriction training on the quadriceps femoris and on knee stability after anterior cruciate ligament reconstruction.Methods:Forty patients recovering from anterior cruciate ligament reconstruction were randomly divided into an experimental group and a control group, each of 20. In addition to routine rehabilitation training, the control group was given routine knee flexion and extension strength training, while the experimental group trained for an additional 20 minutes doing knee flexion and extension resistance training with the blood pressure in their groins at 70% of their individual arterial occlusive pressure. (The mean pressure was (123±11.23)mmHg). The training lasted 8 weeks, three times a week. Knee function and hamstring and quadriceps peak torque were assessed before and after the intervention using a Lysholm scale and Humac Norm isokinetic muscle strength tests.Results:There were no significant differences between the two groups in any of the measurements before the training. After the intervention, all of the measurements had improved significantly in both groups, with the average Lysholm score, H/Q% and peak torque of the experimental group significantly better than the control group′s averages.Conclusions:Blood flow restriction training can improve the effectiveness of quadriceps femoris strength, knee stability and knee function training after anterior cruciate ligament reconstruction.

Abstract: Objective To analyze the epidemiological characteristics of viral hepatitis E in Fujian Province from 2012-2021, and to provide scientific evidence for the prevention and control of hepatitis E in the future. Methods Descriptive epidemiological method was used to analyze hepatitis E cases in Fujian Province from 2012 to 2021. Results From 2012 to 2021, a total of 8 877 cases of hepatitis E were reported in Fujian Province from 2012-2021. The overall incidence rate showed a decreasing trend (χ2trend =458.14, P<0.001), with the lowest incidence rate of 1.32/100 000 in 2020 and an annual average incidence rate of 2.29/100 000 per year. The incidence was higher in winter and spring, with the months of March and April having the highest number of reported cases (2 146, 24.17%) and the fewest cases were reported in September (571, 6.43%). The difference in reported incidence rates between cities was statistically significant (χ2=1 877.75, P<0.01). The comprehensive experimental zone of Pingtan had the highest average reported incidence rate of 6.03/100 000, while Zhangzhou had the lowest at 0.94/100 000. The number of male cases was higher than the number of female cases, with a male to female ratio of 2.04∶1. The disease was most prevalent among middle-aged and elderly individuals, with the age group of 40-<65 years having the highest number of reported cases, accounting for 57.44% (5 099/8 877) of all cases. The age group of 50-<55 years had the highest reported incidence, with the number of reported cases increasing with age below 50 years, but decreasing with age over 50 years. As for occupational distribution, peasants had the highest proportion of the disease, accounting for 34.49% (3 062 cases) of the total cases. Conclusions The reported incidence rate of hepatitis E in Fujian showed a downward from 2012 to 2021. Due to the impact of COVID-19, incidence of the lowest was 2020, but it did not reflect the true situation of the disease, which may have affected trend of hepatitis E. In order to control and reduce the incidence of hepatitis E, efforts should be made to increase publicity and education on health knowledge and vaccination among key areas and populations, strengthen monitoring and diagnostic capability, and implement comprehensive prevention and control measures.

Objective:To explore any effect of training assisted by a pelvic rehabilitation robot on trunk control and walking after cerebral infarction.Methods:Forty cerebral infarction survivors with hemiplegia were randomly divided into an experimental group and a control group, each of 20. Both groups were given routine neurological medication and rehabilitation training, while the experimental group was additionally provided with 20 minutes of robot-assisted gait training daily, five times a week, for 4 weeks. Before and after the intervention, the motor function, walking function, trunk control and pelvic movement were assessed using a simplified version of the Fugl-Meyer assessment (FMA-LL), functional ambulation categories (FAC) and the trunk control test (TCT).Results:After the treatment, significant improvement was observed in all of the above measurements in both groups. The average FMA-LL, FAC and TCT results of the experimental group as well as their average pelvic lateral displacement, height displacement, rotation angle and roll angle were all significantly superior to the control group′s averages.Conclusions:Robot-assisted training can effectively improve lower limb motor functioning, trunk control, walking and pelvic motion after cerebral infarction, with better curative effect than routine rehabilitation training alone.

Objective:To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed.Methods:The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up.Results:All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia.Conclusions:Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.
