OBJECTIVE:To provide reference for health service support at high altitude area. METHODS:375 servicemen who rapidly entered high altitude area were investigated by questionnaire in 2013 to investigate the compliance of using high alti-tude special medicines and incidence of mountain sickness and analyze its correlation. RESULTS:375 questionnaires were distribut-ed and 324 questionnaires were collected with effective response rate of 86.4%. The utilization rate of Multivitamin tablet,Skin cream and Lip balm for high altitude area were 30.9%,13.3% and 40.1% respectively. The compliance of using high altitude spe-cial medicines had effect on the incidence of related mountain sickness. The incidence of mountain sickness of people who followed the physician’s instructions was significantly lower than those who did not. The difference was statistically significant(P<0.05). CONCLUSIONS:High altitude special medicines can relieve and prevent the mountain sickness. But the overall compliance of us-ing high altitude special medicines was not ideal. The education of high altitude special medicines should be strengthened,and dos-age forms and medicine instruction should be enhanced to improve its compliance and play better protective effect.

Objective: To investigate the molecular mechanism and identify potential drugs for subthreshold depression (SD), and elucidate the detalied mechanism of Danzhi Xiaoyao powder (DZXY) in SD. Methods: Using RNA-sequencing, we identified differentially expressed genes (DEGs) in leukocytes of SD compared to healthy controls, deciphered their functions and pathways, and identified the hub genes of SD. We also assessed changes in leukocyte transcription factor activity in patients with SD using the TELiS platform. The Connectivity Map database was retrieved to screen candidate drugs for SD. Based on network pharmacology, we elucidated the “multi-component, multi-target, and multi-pathway” mechanism of DZXY in the treatment of SD. Results: We identified 1080 DEGs (padj <0.05 and |log2 (fold change)| ≥ 1 & protein coding) in the leukocytes of patients with SD. These DEGs, including hub genes, were primarily involved in immune and inflammatory response-related processes. Transcription factor activity analysis revealed similarities between the leukocyte transcriptome profile in SD and the conserved transcriptional response to adversities in immune cells. Connectivity Map analysis identified 28 potential drugs for SD treatment, particularly SB-202190 and TWS-119. Constructing the “Direct Compounds-Direct Targets-Pathways” network for DZXY and SD revealed the curative mechanisms of DZXY in SD, primarily including inflammatory response, lipid metabolism, immune response, and other processes. Conclusion These results provide new insights into the characteristics and functional changes of leukocytes in SD, partially illustrate the pathogenesis of SD, and suggest potential drugs for SD. The curative mechanisms of DZXY in SD are also partially elucidated.

OBJECTIVETo explore the neuropsychological characteristics of children with attention deficit hyperactivity disorder (ADHD).

METHODSNeuropsychological tests, including visual working memory, Stroop test, digits inverse reciting, vocabulary fluency, Wisconsin card sort test (WCST), and Temporal discounting were used to evaluate the capacity of response inhibition, phonological working memory, visual working memory executive function and delayed satisfying capacity of subjects.

RESULTS1. The ADHD children spent longer time [ADHD-I (84(20), ADHD-C: 98 (31), normal: 70 (28)] to accomplish color naming and made more errors [ADHD-I: 3 (3), ADHD-C: 6 (19), normal: 2 (5)] than the normal control when the color was inconsistent with the word meaning in Stroop test (P < 0.01). 2. The scores of digits reciting [ADHD-I: 3 (3), ADHD-C: 3 (4), normal 4 (4)] inverse was lower in ADHD than in normal control (P < 0.01). 3. The representation of ADHD was poorer than normal control in visual working memory [ADHD-I: 21 (3), ADHD-C: 20 (5), Normal: 20 (3)], and in delayed visual memory [ADHD-I: 19 (5), ADHD-C: 19 (5), Normal: 20 (5)] (P < 0.01). 4. The scores of vocabulary fluency [ADHD-I: 1 (1), ADHD-C: 2 (1), normal: 0 (0)] was lower in ADHD than in normal control (P < 0.01). 5. In WCST, the ADHD children made more errors [ADHD-I :15 (17), ADHD-C: 15 (15), normal: 13 (13)] and less classification [ADHD-I: 5 (4), ADHD-C: 5 (4), normal: 5 (3)] than normal control (P < 0.01). 6. In Temporal discounting, the ADHD children showed significantly more impairments than normal control did (P < 0.01). 7. There was significant difference between the two subtype groups on some tests (P < 0.01).

CONCLUSIONSObvious cognitive impairments were found in children with ADHD, involving poor response inhibition, impaired working memory, dysfunction of planning and set-shifting, and there was no significant difference between the two subtype groups.

'Shuhui527' is a promising restorer line bred by Rice Research Institute of Sichuan Agricultural University in recent years. However, this line is susceptible to Bacterial Blight (BB), which limits its use. The IRBB60, from the International Rice Research Institute (IRRI), contains dominant genes Xa21 and Xa4 conferring resistance to BB. The objective of this study is to improve the BB resistance of 'Shuhui527' by introgressing Xa21 and Xa4, the two broad-spectrum BB resistance genes, into 'Shuhui527' with IRBB60 as the donor, pTA248 and MP12, linking tightly with Xa21 and Xa4 respectively as DNA markers. BC1 F1 progenies of (Shuhui527 x IRBB60), containing Xa21 and Xa4 identified using PCR screening and with agronomic traits including plant type, grain type and days to heading etc similar to those of 'Shuhui527', were subsequently backcrossed to 'Shuhui527' and self-pollinated to generate BC2 F1 and BC1 F2 . The BC3 F1 and BC3 F2 were subsequently developed using the same approach. Among the 20 BC3 F2 plants, homozygous Xa21 and Xa4,10 plants were the most similar to 'Shuhui527' in the agronomic traits, and were screened using 120 pairs SSR and 100 pairs RAPD markers. Based on the results of the background screening and the performance of the agronomic traits, 5 plants were identified as improved-'Shuhui527' and designated as 527R-5, 527R-6, 527R-8, 527R-9 and 527R-10. The improved-' Shuhui527' lines expressed high resistance to Xanthomonas oryzae pv . oryzae (Xoo) stains C I - C VII, P1 and P6. The evaluation of the polymorphisms and selection accuracies of pTA248 and MP12 demonstrated that the polymorphisms of the two markers were obvious and co-dominant and the accuracies were more than 97% and 83% respectively, indicating the two markers are good for Xa21 and Xa4 in Molecular Marker-assisted Selection.

OBJECTIVETo evaluate the abilities of population-based birth defects surveillance system (PBBDSS) and hospital-based birth defects surveillance system(HBBDSS).

METHODSWe used capture-mark-recapture method(CMR) to analyze the data of the two kinds of birth defects surveillance systems from 1 Oct. 2006 to 31 Dec. 2006 in a county of Hunan province. Data from PBBDSS were defined as the first source and data from HBBDSS were defined as the second source.

RESULTS49 and 28 birth defect cases were found from PBBDSS and from HBBDSS respectively. Among these cases, 20 were marked. With the method of CMR, the estimated birth defects cases were 68 (95% CI: 56-70). The coincident rates of PBBDSS and HBBDSS were 72.1% and 41.2%, while the total coincident rates was 83.8% and the coincident rates from different sources was 57.1%. The unreported rates of PBBDSS and HBBDSS were 27.9% and 58.8%.

CONCLUSIONNot only the HBBDSS but also the PBBDSS appeared to have had high unreported rates, suggesting that we could use CMR to adjust the rate of birth defects from the birth defects surveillance data.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eighty-two colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P=0.011). The patients with IL10 rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P=0.007) and in multivariate Cox regression model (P=0.044) adjusting for age, gender, carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion, and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

OBJECTIVETo improve Madigan prostatectomy (MPC) for a much satisfactory effect in open surgery.

METHODSA total of 52 patients with benign prostatic hyperplasia (BPH) were treated using MPC. The MPC procedure was modified by exposing anterior prostatic urethra near the bladder neck and conjunction with cystotomy. This modified procedure preserved prostatic urethra intact and could also deal with intracystic lesions at the same time.

RESULTSThe intact of prostatic urethra was kept completely or almost for 48 cases. The hemorrhage amount during modified procedure was a less. The mean operative time was 120 minutes. The 35 patients had been followed up for 1 - 12 months. The average Qmax was 18.9 ml/s. The cystourethrography revealed that the urethra and bladder neck were intact in 8 patients postoperatively. Furthermore, the prostatic urethra was obviously wider after modified MPC.

CONCLUSIONSThe modified MPC can reduce the urethra injury and enlarge the MPC indications. The modified technique is easy to perform with little complications and much more satisfactory clinical result. The modified MPC is highly recommended.
