Progress of suspension in the treatment of severe mixed hemorrhoids / 国际外科学杂志

The incidence of severe mixed hemorrhoids is increasing year by year, and its surgical method has always been the focus in the study of anoenterology. On the basis of anal cushion downward movement theory, anal cushion suspension surgery moves up prolapsed anal cushion by suturing or ligating the mucosa above the dentate line. This not only ensures the effect of surgical treatment, but also protects the structure and function of the canal and anus in the most fine, which is in line with the minimally invasive treatment idea of severe mixed hemorrhoids, and is gradually widely used in clinical practice. As a new surgical method, anal cushion suspension surgery has unique advantages in treating severe mixed hemorrhoids, especially in severe prolapsed hemorrhoids. This paper will analyse the key points of anal cushion suspension surgery combined with procedure for prolapse and hemorrhoids, milligan morgan, hemorrhoidal artery ligation, automatic ligation of hemorrhoids, injection sclerotherapy, laser ablation and mixed surgeries respectively, in order to provide reference for clinicians to operate on severe mixed hemorrhoids.

Retrospective and cost-effective analysis of the result of Changsha Municipal Public Welfare Program by Noninvasive Prenatal Testing / 中华医学遗传学杂志

OBJECTIVE@#To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program.@*METHODS@#A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed.@*RESULTS@#NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035.@*CONCLUSION@#NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.

Correlation of childhood trauma and cognitive function in patients with schizophrenia / 中华行为医学与脑科学杂志

Objective:To explore the relationship between the childhood trauma and neruocognition in patients with schizophrenia.Methods:Sixty-two patients with schizophrenic were selected from Anhui mental health center, and sixty-three community health controls were selected. All subjects were assessed with the childhood trauma questionnaire (CTQ), Wisconsin card sorting Test (WCST), attention network test (ANT), verbal fluency test (VFT) and digit span test (DST). SPSS 17.0 was used for statistical analysis. t-test was used to compare the measurement data of normal distribution and Mann-Whitney U test was used to compare the measurement data of non-normal distribution. Spearman correlation analysis was used to analyze the relationship between CTQ score and cognitive function score. Results:Compared with health controls(34.00(30.00, 37.00), 6.00 (5.00, 7.00), 5.00(5.00, 5.00), 5.00(5.00, 5.00), 9.00(6.00, 11.00), 7.00(6.00, 10.00)), the total score of CTQ, subscores of emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect in patients with schizophrenia were significantly increased (48.50(37.75, 57.00), 9.00(6.00, 12.25), 7.00(5.00, 9.25), 5.50(5.00, 7.25), 13.00 (9.00, 16.25), 11.00(8.00, 13.00)) ( Z=-4.781--6.724, all P<0.01). Compared with the control group, the number of WCST classification completed in the patient group was lower, while the number of wrong answers, continuous answers and persistent errors increased ( Z=-5.655--6.060, all P< 0.01). The correct rate of ant decreased, but the reaction time increased ( Z=-5.796, -6.094, all P< 0.01). VFT and DST scores were decreased ( Z=-3.492--8.499, both P< 0.01). In patients with schizophrenia, CTQ sexual abuse subscore were negatively correlated with completed categories scores ( r=-0.384) and positively correlated with total errors ( r=0.360), perseverative responses( r=0.394) and perseverative errors ( r=0.381) on WCST(all P<0.01). CTQ physical neglect scores were negatively correlated with the ANT correct ratio( r=-0.400) and conflict resolution( r=-0.417) (all P<0.01). CTQ emotional neglect scores were negatively correlated with VFT scores( r=-0.345) ( P<0.01). The significant associations remained after controlling for age, education and PANSS scores. Conclusion:Patients with schizophrenia experience more traumatic events in their early years and have extensive cognitive defects. The childhood trauma has negative effects on cognitive flexibility, attention, memory and speech function in patients with schizophrenia.However, the positive correlation between childhood trauma and executive conflict of attention network needs to be further verified and explored.

Advances in studies on susceptibility genes of bronchial asthma / 国际儿科学杂志

Asthma is a chronic inflammatory disease in the respiratory tract,which is composed of eosinophils,mast cells,T cells,airway epithelial cells and other inflammatory cells.Globally,the incidence of the disease increases year by year,which brings heavy health and financial burden to the patients,their families and the society.At present,much progress has been made in the study of asthmatic susceptibility genes with advances in genome-wide association studies(GWAS) and whole genome sequencing(WGS).This article describes the new development of asthma susceptibility genes and gene testing methods,to illustrate the association between asthma phenotypes and susceptibility genes.Some genes,such as interleukin-33 (IL-33)and thymic stromal lymphopoietin(TSLP),are likely to be potential biomarkers.These studies have certain guiding significance for the diagnosis and treatment of asthma.

A correlation study of humor experience and theory of mind in schizophrenia / 中华行为医学与脑科学杂志

Objective To explore humor experience and its relationship with theory of mind in patients with schizophrenia. Methods sixty?one schizophrenic patients without treatment and sixty?three healthy subjects were assessed with the Humor Picture Test ( HPT) ,Humor Video Test ( HVT) and the Theory?of?Mind Picture?Se?quencing Task ( ToM?PST) . Results Compared with healthy subject in HPT,schizophrenic patients showed sig?nificantly higher non?humor picture rating score (24.41 ± 8.82 vs 28.41 ± 11.56, P<0.05),and less humor picture rating score (45.65 ± 11.49 vs 34.41 ± 13.06, P<0.05). Compared with healthy subject in HVT,schizophrenic patients also showed significantly less humor video rating score (3.56 ± 0.57 vs 2.46 ± 0.79, P<0.01) and the number of standard humorous moments (3.68 ± 1.19 vs 2.42 ± 1.40, P<0.01) and the sensitivity of standard hu?morous moments?d’(humor) score (1.11 ± 0.46 vs 0.47 ± 0.42, P<0.01). Schizophrenic patients had significant?ly less total score (39.89 ± 12.33 vs 58.76 ± 0.64, P<0.01) of ToM?PST compared to normal control. Correlation analysis showed a negative correlation between d’ ( humor) score and the Positive and Negative Syndrome Scale ( PANSS) total score ( r=-0.380, P<0.01) for the patients. There was significantly negative correlation between non?humor picture rating score and ToM?PST total score ( r=-0.316, P<0.05) ,and positive correlation between d’ (humor) score and ToM?PST total score ( r=0.400, P<0.01) in schizophrenic patient. After controlling for the PANSS total score,the correlation between d’(humor) score and ToM?PST total score remained significant. Conclusion Schizophrenic patients have poor humor experience,which is related to the impairments of theory of mind.Humor experience deficit may share a common neuropsychological base with the impairment of theory of mind.

Effects of magnetic field on the behaviors of depression rat model / 中华物理医学与康复杂志

Objective To study influences of magnetic field on behavior of depressive rats under chronic unpredictable mild stress,and possible mechanisms under such phenomena.Methods Thirty-six Wistar rats were divided into model group,magnetic field group and control group (n =12 in each group) according to random number table.The model group and the magnetic field group received CUMS stimulation daily for 5 weeks,while the control group received no any treatment.At the end of the fifth week,rats in the magnetic field group were placed in the center of a magnetic machine (400 mT),and the model group was raised freely for4 weeks.The severity of depressive behaviors,cortisol levels and contents of C-reactive protein in blood and urine sample were tested pre-treatment,at the end of 5 weeks and 9 weeks.Results After 5 weeks,consumption of glucose solution of the control group was higher than the other two groups (P ＜ 0.05).After 5 and 9 weeks,body weights of the magnetic group and the model group were lower than the control group (P ＜ 0.05).At the end of 9 weeks,performance of the magnetic group as indicated by frequency of grid crossing,grooming time and suspending tail test were improved to a significantly greater extent than the other two groups (P ＜ 0.05).In addition,the urine content of cortisol in 24 hours in magnetic field and model groups was higher than the control group at the end of 5 weeks,and the serum level of cortisol in the magnetic field group were significantly higher than the model group at the end of 9 weeks (P ＜ 0.05).Conclusion The 400mT magnetic field can reduce the severity of behavior changes of rats with CUMS-induced depression,which might be attributable to its influence on the cortisol levels in blood and urine.
