【Objective】 To analyze the height growth of children aged 6 - 15 years in Nanning, Guangxi Zhuang Autonomous Region, so as to provide evidence for the assessment of local children′s height development. 【Methods】 A total of 25 225 children aged 6 - 15 years were selected to get their physical examination data from 41 primary schools in Nanning by stratified cluster sampling method in December 2021.Then the height data were compared with the current domestic standards. 【Results】 The average height of boys in Nanning was lower than the national standard before the age of 10 years and 7 months, and the gap with the national standard gradually narrowed after the age of 10 years and 7 months. The average height of boys in Nanning City exceeded the national standard between the age of 11 years and 1 month and 13 years and 6 months, and then lagged behind the national standard again after the age of 13 years and 7 months. The mean height of girls in Nanning City was lower than the national standard height in several age groups, and it was more obvious before the age of 9 years and 7 months. The proportion of height ≤-2s,≤-s,≥ +s and ≥+2s in boys aged 6 to 15 years in Nanning City fluctuated from 2.59% to 6.04%, 12.09% to 23.43%, 7.18% to 18.79% and 0.93% to 3.14%, respectively; the total proportions were 4.56%, 17.46%, 11.35% and 1.74%, respectively; the minimum/maximum proportion values of each height group were at 11 years old /8 years old, 14 years old/8 years old, 8 years old/12 years old, and 6 years old/11 years old, respectively. The proportions of girls aged 6 - 15 years in Nanning City with height ≤-2s, ≤-s, ≥+s, and ≥+2s fluctuated from 2.06% to 5.19%, 9.35% to 25.15%, 8.21% to 15.80% and 1.23% to 3.49%, respectively; the total proportions were 3.38%, 16.91%, 11.97% and 2.29%, respectively; and the minimum/maximum proportion values of each height group were at 13 years old/6 years old, 12 years old/6 years old, 7 years old/12 years old, and 6 years old/11 years old, respectively. 【Conclusions】 The overall height level of children in Nanning is still lower than the national level, with short prepubertal basal heights, an earlier age of onset of accelerated pubertal height, and a shorter duration of accelerated pubertal height in boys. Strengthening pre-pubertal height management and emphasizing the onset and duration of children′s pubertal development, especially the height development of boys during puberty, can help improve the adult lifelong height of children in this region.

This study aimed to investigate the prevalence and clinical characteristics of epilepsy in patients with patent foramen ovale (PFO) and the effect of PFO closure on seizures. Patients diagnosed with PFO were recruited and underwent brain magnetic resonance imaging, electrocardiography, transesophageal echocardiography, and transthoracic echocardiography with right ventriculography. In patients with epilepsy, electroencephalography was performed. A total of 110 patients completed the assessment. A chief complaint of chest tightness or palpitations was proportionately higher in patients aged<18 years, whereas headaches and seizures were higher in patients aged≥18 years ( χ2=4.69 ,P<0.05). Comorbid epilepsy was observed in 20.9% of patients with PFO. The age at admission in the epileptic group (14-66(27±14)years) was significantly lower than that in the non-epileptic group (16-81(38±21)years) and that in patients with headache as the chief complaint (16-68(39±12)years) ( t=3.29, P<0.05). The multivariate analysis found no risk factors related to the prognosis of epilepsy. The incidence of epilepsy was significantly higher in patients with PFO than in the general population.

Many people affected by fragile X syndrome (FXS) and autism spectrum disorders have sensory processing deficits, such as hypersensitivity to auditory, tactile, and visual stimuli. Like FXS in humans, loss of Fmr1 in rodents also cause sensory, behavioral, and cognitive deficits. However, the neural mechanisms underlying sensory impairment, especially vision impairment, remain unclear. It remains elusive whether the visual processing deficits originate from corrupted inputs, impaired perception in the primary sensory cortex, or altered integration in the higher cortex, and there is no effective treatment. In this study, we used a genetic knockout mouse model (Fmr1^KO), in vivo imaging, and behavioral measurements to show that the loss of Fmr1 impaired signal processing in the primary visual cortex (V1). Specifically, Fmr1^KO mice showed enhanced responses to low-intensity stimuli but normal responses to high-intensity stimuli. This abnormality was accompanied by enhancements in local network connectivity in V1 microcircuits and increased dendritic complexity of V1 neurons. These effects were ameliorated by the acute application of GABA_A receptor activators, which enhanced the activity of inhibitory neurons, or by reintroducing Fmr1 gene expression in knockout V1 neurons in both juvenile and young-adult mice. Overall, V1 plays an important role in the visual abnormalities of Fmr1^KO mice and it could be possible to rescue the sensory disturbances in developed FXS and autism patients.

To explore the pharmacogenomic markers that affect the platinum-based chemotherapy response in non-small-cell lung carcinoma (NSCLC), we performed a two-cohort of genome-wide association studies (GWAS), including 34 for WES-based and 433 for microarray-based analyses, as well as two independent validation cohorts. After integrating the results of two studies, the genetic variations related to the platinum-based chemotherapy response were further determined by fine-mapping in 838 samples, and their potential functional impact were investigated by eQTL analysis and in vitro cell experiments. We found that a total of 68 variations were significant at P < 1 × 10^-3 in cohort 1 discovery stage, of which 3 SNPs were verified in 262 independent samples. A total of 541 SNPs were significant at P < 1 × 10^-4 in cohort 2 discovery stage, of which 8 SNPs were verified in 347 independent samples. Comparing the validated SNPs in two GWAS, ADCY1 gene was verified in both independent studies. The results of fine-mapping showed that the G allele carriers of ADCY1 rs2280496 and C allele carriers of rs189178649 were more likely to be resistant to platinum-based chemotherapy. In conclusion, our study found that rs2280496 and rs189178649 in ADCY1 gene were associated the sensitivity of platinum-based chemotherapy in NSCLC patients.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective: To investigate the automatic implicit attitude and explicit stigma of mental illness, and the intervention effectiveness on the stigma of mental illness in college students. Methods: Single category implicit association test(SC-IAT) and questionnaire survey were used to study the degree of implicit and explicit mental illness stigma among 30 college students of Peking University, and investigated the effect of two strategies, education and contact.Data were analyzed by SPSS 22.0 with t-test and variance analysis. Results: The D values of SC-IAT in the three dimensions of cognitive evaluation, emotional response and behavioral tendency of college students were 0.29±0.37, 0.24±0.43, and 0.10±0.43.There was a statistically significant difference between the cognitive evaluation dimension, the emotional response dimension and 0(t=4.069, P<0.01; t=2.925, P<0.01). There was no statistically significant difference between the implicit stigma and the 0 in the behavioral tendency dimension(t=1.423, P=0.167). In the explicit stigma, the mercy dimension score(1.94±0.61) was lower than the median, and the difference was statistically significant(t=-12.286, P<0.01), while the scores of anger dimension(4.62±0.44) and fear dimension (4.55±0.31) were higher than the median(t=13.243, 3.200, both P<0.01). There were no significant differences in the values of implicit and external stigma among pre-intervention, education intervention and after contact(P>0.05). The correct rates of questions "Which of the following situations do you think are considered mentally unhealthy? " and "Which of the following disorders are mental illnesses" (42±13)%, (54±13)%) increased after receiving educational intervention ((49±12)%, (64±13)%), the difference was statistically significant (F=3.682, P<0.05; F=3.576, P<0.05). Conclusion College students have implicit mental illness stigma, educational and contact intervention strategies can help improve college students' understanding of relevant knowledge, and cannot improve the level of implicit stigma of college students on mental illness.

Objective To explore the correlation between spinal sagittal balance and quality of life after the treatment of percutaneous kyphoplasty in osteoporotic vertebral compressive fractures. Methods We retrospec-tively enrolled and screened 85 patients with osteoporotic vertebral compression fractures(OVCF),treated by per-cutaneous kyphoplasty(PKP)in spinal surgery department of Shanghai East Hospital from January 2012 to Decem-ber 2016. The full length of the spine X-ray examinations had been taken preoperatively,pre-discharge and during the follow-up and spine-pelvis sagittal parameters included C7 sagittal vertical axis(C7SVA),thoracic kyphosis (TK),lumber lordosis(LL),pelvic incidence(PT)and sacral slope(SS). Shot Form 36 Health Survey Question-naire(SF-36)was used for the scoring. Results In the last follow-up,C7SVA decreased from(35.9 ± 17.1)mm to(30.8 ± 12.8)mm(P=0.002)and SF-36 scores varied significantly(P<0.01). Before the surgery,follow-up 3 days,6 months and 12 months after the surgery,C7SVA was negatively correlated with the general health status in each period of SF-36(r=-0.343,-0.264,-0.272,-0.258;P=0.001,0.015,0.012,0.017). Conclusions PKP has a significant effect on OVCFs and changes the spine-pelvic sagittal balance in patients with OVCF. Spinal-pel-vic sagittal balance is closely related to the quality of life of these patients.

OBJECTIVE:To promote quality control management of TCM decoction piece in secondary and tertiary TCM hospitals, integrated traditional Chinese and western medicine hospitals, and to guarantee the safety of drug use in patients. METHODS:According to 2016 TCM Decoction Piece Management Special Test Score of National Medical Institution made by quality control center of TCM in Shanghai,TCM decoction piece management of 22 secondary and tertiary TCM hospitals, integrated traditional Chinese and western medicine hospitals (14 and 8,respectively) in Shanghai were scored (the total score is 100),summarized and analyzed by on-site inspection from 7 modules,such as pharmaceutical management,acceptance and storage maintenance, dispensing, decocting or outside processing, prescription standardization and prescription review. The suggestions were put forward. RESULTS & CONCLUSIONS:Average score of 22 hospitals was 91.97, and hospitals with excellent(the secondary and tertiary hospitals are 11 and 5,respectively)and good(the secondary and tertiary hospitals are 2 and 3,respectively) score accounted for 95.45％. Those hospitals obtained good score in respect of pharmaceutical management (the total score is 12,scored 11.73). But in many hospitals,there are shortcomings in acceptance and storage maintenance,dispensing, outside processing,prescription standardization and prescription review management. It is suggested to control TCM decoction piece purchase and acceptance,strengthen TCM decoction piece maintenance and storage,enhance TCM decoction piece batch number management, effectively monitor TCM decoction piece outside processing, improve prescription standardization, implement TCM decoction piece prescription comment and standardize prescription name of TCM decoction piece so as to improve total quality of TCM decoction piece management.
