Cancer is a complex disease associated with multiple gene mutations and malignant phenotypes, and multi-target drugs provide a promising therapy idea for the treatment of cancer. Natural products with abundant chemical structure types and rich pharmacological characteristics could be ideal sources for screening multi-target antineoplastic drugs. In this paper, 50 tumor-related targets were collected by searching the Therapeutic Target Database and Thomson Reuters Integrity database, and a multi-target anti-cancer prediction system based on mt-QSAR models was constructed by using naïve Bayesian and recursive partitioning algorithm for the first time. Through the multi-target anti-cancer prediction system, some dominant fragments that act on multiple tumor-related targets were analyzed, which could be helpful in designing multi-target anti-cancer drugs. Anti-cancer traditional Chinese medicine (TCM) and its natural products were collected to form a TCM formula-based natural products library, and the potential targets of the natural products in the library were predicted by multi-target anti-cancer prediction system. As a result, alkaloids, flavonoids and terpenoids were predicted to act on multiple tumor-related targets. The predicted targets of some representative compounds were verified according to literature review and most of the selected natural compounds were found to exert certain anti-cancer activity in vitro biological experiments. In conclusion, the multi-target anti-cancer prediction system is very effective and reliable, and it could be further used for elucidating the functional mechanism of anti-cancer TCM formula and screening for multi-target anti-cancer drugs. The anti-cancer natural compounds found in this paper will lay important information for further study.

Objective:To explore the type distribution and severity of central nervous system(CNS) complications in severe hand, foot and mouth disease (HFMD) cases prior to the introduction of human enterovirus A group 71 type (EV-A71) vaccine, and provide scientific data for early clinical intervention.Methods:A total of 3 583 laboratory-confirmed severe HFMD cases in Jiangsu province during 2010-2016 were collected and analyzed retrospectively. Related early warning signs of increased HFMD severity were estimated with logistic regression analyses.Results:The severity-fatality rate, severity-pediatric intensive care unit(PICU) admission rate, and sequelae rate were 8.09‰(29/3 583), 11.75% (421/3 583)and 5.30‰(19/3 583). Of them, 39.02% (1 398/3 583) patients suffered from mild CNS involvement, 59.22% (2 122/3 583) patients suffered from severe CNS involvement, 1.76%(63/3 583) suffered from critical CNS involvement. The rates of the cases whose age of onset was 6-11 months, the rates of cases with atypical rash, respiratory-related signs and symptoms (shortness of breath, slowed breathing, dyspnea, etc), neurological-related signs and symptoms [(hand and foot shaking, convulsions, lethargy(sleepiness), etc], circulatory-related system signs and symptoms (faster heart rate, abnormal skin color, arrhythmia, cold limbs), laboratory-related indicators (increased white blood cell count, increased lymphocyte count, increased platelet count, increased C-reactive protein, etc), clinical auxiliary examination [electroencephalogram(EEG), brain CT, chest X-ray)] were highest in the critical CNS involvement group, and the differences were significant ( P<0.05). Multivariate logistic regression analysis showed that with the increase of proportion of convulsions, slowed breathing, vomiting, meningeal irritation and other 7 variables, the severity of CNS complications increased ( P<0.05). Conclusions:The indicators such as easily startled, slow breathing, vomiting, elevated lymphocytes, abnormal EEG and other indicators have important clinical significance for children with severe HFMD to progress to CNS complications of different severity.

OBJECTIVE: To study the clinical features of sleep-disordered breathing (SDB) in children with neuromuscular disease (NMD). METHODS: A retrospective analysis was performed on the medical data of 18 children who were diagnosed with NMD and underwent polysomnography (PSG) (NMD group). Eleven children without NMD who had abnormal sleeping habit and normal sleep structure on PSG were enrolled as the control group. The two groups were compared in terms of the daily and nocturnal symptoms of SDB, incidence rate of obstructive sleep apnea (OSA), pulmonary function, end-tidal partial pressure of carbon dioxide (PetCO RESULTS: In the NMD group, 16 children (89%) had related daily and nocturnal symptoms of SDB, and the youngest age was 1 year at the onset of such symptoms. Compared with the control group, the NMD group had significant reductions in total sleep time and sleep efficiency ( CONCLUSIONS There is a high proportion of children with SDB among the children with NMD, and SDB can be observed in the early stage of NMD, which results in the damage of sleep structure and the reduction in sleep efficiency. Respiratory events are mainly obstructive events, and oxygen reduction events are mainly observed during REM sleep.

OBJECTIVE: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province. METHODS: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017. RESULTS: The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01). CONCLUSIONS Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

Purpose::Blast lung injury (BLI) is the most common damage resulted from explosion-derived shock wave in military, terrorism and industrial accidents. However, the molecular mechanisms underlying BLI induced by shock wave are still unclear.Methods::In this study, a goat BLI model was established by a fuel air explosive power. The key genes involved in were identified. The goats of the experimental group were fixed on the edge of the explosion cloud, while the goats of the control group were 3 km far away from the explosive environment. After successful modeling for 24 h, all the goats were sacrificed and the lung tissue was harvested for histopathological observation and RNA sequencing. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) analysis were performed to identify the main enriched biological functions of differentially expressed genes (DEGs). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to verify the consistency of gene expression.Results::Of the sampled goat lungs, 895 genes were identified to be significantly differentially expressed, and they were involved in 52 significantly enriched GO categories. KEGG analysis revealed that DEGs were highly enriched in 26 pathways, such as cytokine-cytokine receptor interaction, antifolate resistance, arachidonic acid metabolism, amoebiasis and bile secretion, JAK-STAT, and IL-17 signaling pathway. Furthermore, 15 key DEGs involved in the biological processes of BLI were confirmed by qRT-PCR, and the results were consistent with RNA sequencing.Conclusion::Gene expression profiling provide a better understanding of the molecular mechanisms of BLI, which will help to set strategy for treating lung injury and preventing secondary lung injury induced by shock wave.

Background:Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD).The study is to evaluate the efficacy and safety of tACS treating MDD.Methods:This is an 8-week,double-blind,randomized,placebo-controlled study.Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min,77.5-Hz,15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4),following a 4-week observation period (week 8).The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8.Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17,the proportion of participants having improvement in the clinical global impression-improvement,the change in HDRS-17 score (range,0-52,with higher scores indicating more depression) over the study,and variations of brain imaging and neurocognition from baseline to week 4.Safety will be assessed by vital signs at weeks 4 and 8,and adverse events will be collected during the entire study.Discussion:The tACS applied in this trial may have treatment effects on MDD with minimal side effects.

Objective: To evaluate the diagnostic value of bronchoalveolar lavage (BAL) for pulmonary complications in patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and its safety. Methods: Patients with pulmonary complications after allo-HSCT underwent BAL. Microbiological smears, culture, PCR of CMV-DNA, EBV-DNA and TB-DNA, macro genomes new generation sequencing (mNGS) techniques were performed to detect pathogens in BAL fluid (BALF) . Results: A total of 73 allo-HSCT patients with 86 times of pulmonary complications enrolled this prospective study. They underwent 132 times of BAL procedures. The clinical diagnoses of 88.4% cases were made based on BALF analysis. Of them, 67 cases (77.9%) had infectious pulmonary complications, including 29 cases (33.7%) of fungal infection, 18 cases (20.9%) of mixed infection, 11 cases (12.8%) of viral infection and 9 cases (10.5%) of bacterial infection. The other 9 cases (10.5%) of non-infectious pulmonary complications included 8 cases (9.3%) of idiopathic pneumonia syndrome (IPS) and 1 case (1.2%) of pulmonary infiltration of lymphoma. The diagnoses of the remaining 10 cases (11.6%) were not determined. The platelet counts of 33 patients were less than 50×10(9)/L before BAL. None of them developed severe bleeding complications during or after BAL. Transient fever occurred in 10 patients after BAL. Blood cultures showed staphylococcal bacteremia in them and anti-infection therapies were effective. No life-threatening complications occurred in all of the patients during or after BAL. Conclusion: BALF analysis was informative for the diagnosis of pulmonary complication and safe for patients with pulmonary complications after allo-HSCT.

Objective To evaluate the risk of microsurgery and reduce the incidence of postoperative complications in patients with lon-gitudinal fissure meningioma. Methods The clinical data of 106 patients with longitudinal fissure meningioma after microsurgery in the neu-rosurgery department of Xuzhou medical university from January 2011 to December 2017 were retrospectively analyzed.Longitudinal fissure meningioma were defined as the meningioma whose base were attached to the brain’s sickle sinus,sagittal sinus and the brain’s sickle sagit-tal sinus.Patients were divided into two groups according to whether there were postoperative complications.The gender,age,chief complaint symptoms,tumor base,tumor location,tumor size,tumor shape,MR enhancement,MR peritoneal edema, peritoneal adhesion of central sulcus vein and drainage vein,tumor invasiveness,tumor boundary,previous history of circulatory system were compared.Univariate analysis was per-formed on these factors to screen out the influencing factors of patients with postoperative complications.Binary logistic regression analysis was performed on the factors with statistical significance.Results Central sulcus vein and drainage vein adhesion were independent protective factors for postoperative complications.The risk of postoperative complications in patients without adhesion at peri-tumor stage was only 0.209 times of that in patients with adhesion.Conclusion For patients with longitudinal fissure meningioma,preoperative risk of postoperative com-plications can be assessed objectively according to the condition of central sulcus vein and drainage vein adhesion around the tumor.In the treatment of patients with obvious peritumoral vascular adhesion,the central sulcus vein and drainage vessels should be carefully protected to significantly reduce the incidence of postoperative complications.

Objective To analyze the role of telehealth?based dialysis registration systems in real?time and dynamic reflection of renal anemia in hemodialysis (HD) patients, and discuss the prospect of its application in dialysis registration management. Methods The Red China project was to build up a dialysis registration system based on the WeChat mobile terminal platform. Demographic and baseline laboratory parameters such as age, gender, primary disease, dialysis age, creatinine were recorded in this system. Hemoglobin (Hb) level was monthly recorded. The platform generated Hb statistics report for each HD center monthly, including the detection rate, target rate and the distribution level of Hb, and released it to physicians through the WeChat terminal of mobile phone. After that, physicians could change the treatment of anemia individually on basis of this report. Here the demographic and baseline laboratory parameters, the detection rate, target rate, the average level and the distribution of Hb from June 2015 to October 2017 after the project launched were analyzed. Results From June 2015 to October 2017, 8392 maintenance HD patients from 28 HD centers in Shanghai were enrolled, of whom 5059(60.3％) were male.The average rate age was (60.5 ± 13.7) years old. Baseline average Hb was (108.3±16.0) g/L. Baseline detection rate and target rate were 54.2％and 47.5％, respectively. After 28 months follow?up, the detection rate of Hb increased from 54.2％ to 73.6％ (P<0.001), the target rate of Hb increased from 47.5％ to 56.1％ (P<0.001), and the level of average Hb rose from (108.3±16.0) g/L to (110.7±16.0) g/L. The difference between average Hb in two consecutive months was less than 1.3 g/L. Conclusions The telehealth?based dialysis registration system can timely report the anemia situation of HD patients, which may improve the awareness rate of anemia, the degree of attention and the compliance of anemia monitoring, so as to improve the detection rate and target rate of Hb and reduce the fluctuation of Hb, which helps to maintain the HD patients to correct anemia in a timely, stable and long?term way. The telehealth?based dialysis registration system, as an improved mode of dialysis registration is a promising way for long?term management of renal anemia in dialysis patients.
