Objective To study the efficacy of the deroofing-fixation operation for postoperative recurrent simple hepatic cysts (RSHC).Methods 21 patients who developed postoperative RSHC underwent the deroofing-fixation operation at the First Affiliated Hospital,Henan University of Science & Technology from August 2012 to August 2016.The data were analyzed retrospectively.Results The recurrent sites varied and included S6,7 (n=9),S7 (n=5),S8 (n=3) and S7,8 (n=4).The first operations for all these patients were either laparoscopic fenestration or windowing decompression.The recurrence time ranged from 4 to 13 months (average 6 months) after the first operation.All these patients were reoperated using the deroofing-fixation method,i.e.taparotomy,cyst deroofing and cyst edge fixation to the right hepatorenal ligament (n =9),or to the hepatic falciform ligament (n =12).All these patients were followed up for 11 to 60 months after the reoperation,and no recurrence was found.Conclusion The deroofing-fixation is an efficacious operation for post-operative RSHC.

OBJECTIVE: To investigate the diagnostic value of diffusion kurtosis imaging (DKI) histogram analysis in hepatic fibrosis staging. MATERIALS AND METHODS: Thirty-six rats were divided into carbon tetrachloride-induced fibrosis groups (6 rats per group for 2, 4, 6, and 8 weeks) and a control group (n = 12). MRI was performed using a 3T scanner. Histograms of DKI were obtained for corrected apparent diffusion (D), kurtosis (K) and apparent diffusion coefficient (ADC). Mean, median, skewness, kurtosis and 25th and 75th percentiles were generated and compared according to the fibrosis stage and inflammatory activity. RESULTS: A total of 35 rats were included, and 12, 5, 5, 6, and 7 rats were diagnosed as F0–F4. The mean, median, 25th and 75th percentiles, kurtosis of D map, median, 25th percentile, skewness of K map, and 75th percentile of ADC map demonstrated significant correlation with fibrosis stage (r = −0.767 to 0.339, p < 0.001 to p = 0.039). The fibrosis score was the independent variable associated with histogram parameters compared with inflammatory activity grade (p < 0.001 to p = 0.041), except the median of K map (p = 0.185). Areas under the receiver operating characteristic curve of D were larger than K and ADC maps in fibrosis staging, although no significant differences existed in pairwise comparisons (p = 0.0512 to p = 0.847). CONCLUSION: Corrected apparent diffusion of DKI histogram analysis provides added value and better diagnostic performance to detect various liver fibrosis stages compared with ADC.

OBJECTIVE: To investigate the relationship between serum level of homocysteine and the development of collaterals in patients with severe coronary artery stenosis (SCAS). METHODS: Eighty patients with at least one vessel stenosis over 90% among the 3 main vessels of coronary artery were consecutively enrolled into the study according to angiographic estimation. The development of collaterals was classified by Rentrop's method. RESULTS: The serum levels of homocysteine among the single-vessel, bi-vessel and tri-vessel coronary artery disease groups had no significant difference; there was no linear correlation between the serum level of homocysteine and Gensini's score. The level of homocysteine in the poorly developed collaterals was significantly higher than that in the well-developed collaterals in the SCAS patients (P<0.001). Multiple stepwise logistic analysis revealed that homocysteine negatively correlated with the development of collaterals (P<0.001, odds ratio=0.353; 95% confidence interval=0.201 - 0.620), whereas it positively correlated with the number of stenosis vessels. CONCLUSION The serum level of homocysteine is independently and negatively associated with the development of collateral circulation in severe SCAs patients.

OBJECTIVE: To explore the value of transthoracic echocardiography (TTE) in transcatheter closure of atrial septal aneurysm (ASA) combined with secoundum-type atrial septal defect (ASD). METHODS: Fourteen patients (3 males and 11 females) who had ASA combined with secoundum-type ASD were diagnosed by TTE or transesophageal echocardiography. The ASA projected to the right atrium in all patients. The width of basilar part was 13 approximately 24 (18.5+/-3.9) mm, and the vertical extent was 7 approximately 11(9.7+/-1.8) mm. Ten patients combined with single hole ASD and 4 patients with multiple hole ASD. Blood shifting from the left atrium to the right atrium was displayed in color Doppler in all patients. All patients were treated by transcatheter closure under the guiding of X fluoroscopy and TTE, and examined with TTE during the follow-up. RESULTS: Transcatheter closure was successfully performed by 14 occluders in all patients. No residual shunt was detected immediately by TTE after the procedure in all patients. During the 6 approximately 12 month follow-up, no residual shunt or occluder shifting was found, the dimensions of the heart became normal in 11 patients (79%) and were significantly decreased in 4. CONCLUSION Transcatheter closure is feasible in patients with ASA combined with secoundum-type ASD, and extra attention must be paid to the specialty. TTE is very important in case selection before transcatheter closure, and it may be used to monitor and guide the procedure during transcatheter closure.

OBJECTIVEThe purpose of this study was to analyze the electrocardiographic features of the people living in the area with high incidence of unexplained sudden deaths in Yunnan province.

METHODThe electrocardiograms of 338 residents from three villages (Dayao, Ninglang, Heqing) with high incidence of unexplained sudden deaths and one control village (Dali) were analyzed [averaged age was (33.4 +/- 11.7) years, 175 men and 163 women].

RESULTSThe incidence of cardiac arrhythmias was similar low in all groups. The left ventricular hypertrophy was observed in 34.6% of residents from Dayao. QTc significantly prolonged in the residents from all 3 high incidence areas compare the control area of Dali [control (386.8 +/- 27.22) ms, Ninglang (428.92 +/- 25.71) ms, Heqing (440.67 +/- 28.03) ms, Dayao (417.7 +/- 24.00) ms, P < 0.05 vs. control]. Incidence of U wave was significantly higher in Heqing village than that in control village (P < 0.05). The QUc of these 3 villages was: (613.67 +/- 37.34) ms, (597.19 +/- 46.47) ms, (608.59 +/- 39.59) ms respectively, and also significantly longer than the control village of Dali (589.33 +/- 41.27) ms (P < 0.05). The typical pattern of U wave presents as enlarged U wave and apparent T-U complex. In the 7 residents who have the family history of unexplained sudden death, 6 residents have U wave, and 4 of them present typical U wave pattern.

CONCLUSIONThe significant ECG changes in villages with high incidence of unexplained sudden death in Yunnan province were prolonged QTc, enlarged U wave and apparent T-U complex and these ECG features suggested the repolarization abnormalities of the heart in these subjects.

Objective: To inhibit the stemness maintenance potential of endometrial cancer and increase the sensitivity of endometrial cancer side population cells to chemotherapy drugs by inducing extensive deSUMOylation modification of proteins. Methods: Flow cytometry was used to sort and culture CD133(+) CD44(+) KLE endometrial cancer cell clone spheres. Protein expression level of small ubiquitin-related modifier 1 (SUMO1) and two stemness maintenance genes of tumor side population cells, octamer binding transcription factor-4 (Oct4) and sex determining region Y-box2 (Sox2), were detected by western blotting method. Lentivirus-mediated Sentrin/SUMO-specific proteases 1 (SENP1) gene was stably transfected into KLE side population cells. Western blotting was used to detect the protein expressions of SENP1, SUMO1, Oct4 and Sox2. The clone formation rate was compared between KLE side population cells with or without SENP1 overexpression. Flow cytometry was applied to detect cell cycle changes. 3-(4, 5-Dimethylthiazole-2)-2, 5-diphenyl-tetrazolium bromide (MTT) experiment and flow cytometry apoptosis method were used to detect the chemosensitivity of the side population of endometrial cancer cells to cisplatin. Tumor-bearing mouse models of endometrial cancer were established to detect the effect of SENP1 overexpression on the chemotherapy sensitivity of cisplatin. Results: Compared with CD133(-)CD44(-) KLE cells, CD133(+) CD44(+) KLE side population cells could form clonal spheres and express higher levels of SUMO1, Oct4 and Sox2 proteins (P<0.05). Compared with KLE side population cells that were not transfected with SENP1 gene, the expression level of SENP1 protein in KLE side population cells overexpressing SUMO1、Oct4 and Sox2 were lower. The clonal sphere formation rate was reduced from (25.67±5.44)% to (7.46±1.42)%, and cell cycle shifted from G(0)/G(1) phase to G(2) phase. IC(50) of cisplatin decreased from (55.46±6.14) μg/ml to (11.55±3.12) μg/ml, and cell apoptosis rate increased from (9.76±2.09)% to (16.79±3.44)%. Overexpression of SENP1 could reduce the tumorigenesis rate of KLE side population cells in vivo and increase their chemotherapy sensitivity to cisplatin (P<0.05). Conclusion: Overexpression of SENP1 can induce protein deSUMOylation modification, inhibit the stemness maintenance potential of endometrial cancer side population cells, and enhance their chemotherapy sensitivity, which provides a new reference for gene therapy of endometrial cancer.

OBJECTIVE: To present an approach to phenotyping ACEs and explore the association between ACEs and adolescent health risky behaviors based on the social context of China. METHODS: Totally, 5,726 adolescents aged 12-18 years were investigated about their ACEs in the family, peer, school, and personal domains and the occurrence of six types of risky health behaviors (i.e., smoking, drinking, sexual intercourse, self-harm, and suicidal ideation and attempts). Latent class analysis (LCA) was used to explore the ACE patterns. RESULTS: Six latent classes of ACEs were identified, including low adversity, school adversity, school adversity and peer victimization, peer victimization, maltreatment and peer victimization, and high adversity, and associated with risky health behaviors in adolescents. Being physically punished by a teacher, experiencing sexual abuse, and experiencing family trauma most strongly differentiated from the six ACE classes and were correlated with an increased risk for risky adolescent health behaviors. CONCLUSION This study supports a positive association between ACEs and risky adolescent health behaviors. Peer victimization, school adversity and associated contexts need to be considered in future ACE studies.

The incidence of infertility has recently risen. Semen quality is an important male fertility indicator, and dietary factors can affect semen quality. We conducted this systematic review and meta-analysis to determine the effects of healthy dietary patterns on semen quality. A literature search was conducted in 3 databases (Embase, Web of Science and PubMed) on August 21, 2021. The included cross-sectional studies examined the influence of the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and prudent diet patterns on semen quality parameters; six studies (1244 subjects) were included. By comparing high consumption with low consumption of healthy dietary patterns, the results of the meta-analysis showed significantly higher sperm concentrations (mean difference [MD] = 6.88 × 10⁶ ml^-1, 95% confidence interval [CI]: 1.26 × 10⁶ ml^-1-12.49 × 10⁶ ml^-1; P < 0.05), a significant increase in total sperm count (MD = 16.70 × 10⁶, 95% CI: 2.37 × 10⁶-31.03 × 10⁶; P < 0.05), and a significant increase in progressive sperm motility (MD = 5.85%, 95% CI: 2.59%-9.12%; P < 0.01). The sperm concentration, progressive sperm motility, and total sperm count were significantly higher in men with higher versus lower consumption of healthy dietary patterns. However, the results must be interpreted with caution.

Objective To analyze the overall functioning of children with learning disabilities, and develop individualized exercise rehabilitation protocol using International Classification of Functioning, Disability and Health (ICF). Methods Based on the theoretical framework of ICF and the disease diagnosis of International Classification of Diseases (ICD-11), and with the perspective of child development, the functional profiles of cognition, understanding, attention, thinking, motor, and activity and participation of children with learning disabilities were analyzed. A function-oriented and individulized exercise rehabilitation protocol for children with learning disabilities was constructed in light of ICF bio-psycho-social health paradignm and the theory of somatic and mental interaction. Results The functional performance of children with learning disabilities mainly demonstrated in mental dysfunction in physical functioning in the activities and participation limitations, such as learning and applying knowledge, general tasks and demands, and communication. For the environment factors, products and technology for education, products and technology for culture, recreation and sports, and services, systems and policies could also affect children with learning disabilities. Physical activity was beneficial for children with learning disabilities to improve mental and motor functioning and to effectively enhance intellectual, cognitive, attentional, communication, and mobility skills for the overall development of the children. Physical activity for children with learning disabilities was selected according to WHO guidelines for physical activity and sedentary behavior for children, and moderate to vigorous physical activity for at least 60 minutes, as well as high-intensity training no less than three times a week, together with appropriate physical games and leisure physical activities could effectively improve learning outcomes and reduce learning disabilities. Conclusion The health condition, functioning and motor development of children with learning disability had been analyzed using ICD-11 and ICF, and with the theories of somatic and metal interaction and ICF bio-psycho-social model, the holistic and function-oriented exercise rehabilitation program was developed that recommended at least 60 minutes of moderate intensity physical activity, including aerobic exercise and physical games, per day, and at least three times a week of high intensity physical activity of no less than 30 minutes, including plyometrics and physical competition. The development of individualized function-based exercise rehabilitation programs incorporating the learning disability and motor function characteristics of children could effectively improve the cognitive, attentional, and thinking functions of children with learning disabilities, reduce learning disabilities, and promote the overall development of children.
