Arsenic trioxide (ATO) is involved in a variety of biological processes of hepatocellular carcinoma (HCC) cells, including apoptosis induction, proliferation inhibition, invasion and metastasis inhibition, and tumor stem cell inhibition. ATO has a variety of therapeutic approaches in the treatment of HCC, mainly including single drug therapy, combined local therapy, combined systemic therapy, and so on. Further research on the anti-cancer mechanism and clinical application of ATO is expected to provide new ideas for the treatment of liver cancer.

Objective: Empirical findings confirmed that autistic and schizotypal traits are associated with attentional function as well as include various dimensions. So far, no study has reported which dimension of these traits relates to attentional networks. This study aimed to find out whether there are associations between attentional networks and autistic traits; and between attentional networks and schizotypal traits. Methods: A total of 449 volunteers was included in this study, and autism-spectrum quotient (AQ), schizotypal personality questionnaire (SPQ), and attention network test (ANT) were used to measure autistic traits and schizotypal traits. The three independent attentional networks, including alerting network, orienting network, and executive control network, were also measured. Results: Autistic traits were associated with the orienting network, whereas schizotypal traits were associated with the orienting network and executive control network. Furthermore, attentional networks could be predicted by specific dimensions of autistic and schizotypal traits. AQ-attention switching [0.104 (-1.175– -0.025), p=0.041] and AQ-attention to detail [-0.097 (-0.798– -0.001), p=0.049] were significant predictors of orienting network and gender were significant predictor of executive network (Beta=0.107; 95% CI=-0.476–10.139; p=0.031). Whereas, schizotypal dimension “interpersonal” was a significant predictor of all three attentional networks [Alerting: 0.147 (-0.010–0.861), p=0.045; Orienting: 0.147 (0.018–0.733), p=0.040; Executive: 0.198 (0.215–1.309), p=0.006]. Conclusion This study demonstrated that autistic and schizotypal traits were associated with attentional networks. The specific dimensions of autistic and schizotypal traits could predict attentional networks. Nevertheless, the attentional networks predicted with these two traits were different.

Objective To conduct the molecular epidemiologic analysis of Staphylococcus aureus (S.aureus) in the intensive care units(ICUs) and general wards and to compare their clinical characteristics.Methods Ninety-six clinically isolated strains of S.aureus(43 strains from the emergency intensive care unit(EICU) and neurosurgical intensive care unit(NICU) and 53 strains from the general wards) collected from Sepetember 2015 to April 2016 were performed the bacterial identification and antibiotic susceptibility test.The molecular typing was performed by adopting staphylococcal protein A (spa) typing method.Results Among 96 strains of S.aureus,the detection rate of methicillin-resistant S.aureus(MRSA) was 40.6%(39/96),which among 43 strains in ICU was 62.8%(27/43) and which among 53 strains in the general words was 22.6%(12/53).The resistance rates of strains from ICUs to gentamicin,levofloxacin,clindamycin,fosfomycin and minocycline were 23.3%,48.8%,46.5%,32.6% and 32.5% respectively,while which from the general wards were 7.5%,24.5%,18.9%,2.1% and 0% respectively.The Spa typing results showed that the main types of ICUs were t002,t091 and t311.The major epidemic strain was t002(n=16,37.2%) and mainly isolated from EICUs(12 strains),26 spa types were identified among the general wards trains,mainly were t189,t377,t571,t034,t091,t127.Conclusion The detection rate of MRSA in ICUs is higher than that in the general wards,these strains have high resistant rate to routine antibacterial drugs.t002 is the major epidemic strain.The general wards have more spa types with higher genetic diversity.

To summarize the clinical experience of Professor WANG Meng-yong in the treatment of uric acid nephropathy. Professor WANG believes that the disease is mainly caused by spleen and kidney deficiency, disorder of function of Sanjiao, and pathological products, such as phlegm dampness and blood stasis and other metabolic disorders. Therefore, the treatment should distinguish symptoms and essence. Starting from pathogenesis and pathological features of spleen and kidney deficiency and phlegm dampness and blood stasis, the treatment should flexibly apply the methods of nourishing spleen and kidney, reducing phlegm and dispelling humidity, and activating blood and using diuretic of hydragogue to alleviate water retention, which can greatly reduce side effects caused by the long-term use of Western medicine and the onset of gout, and then to help disease recovery.

Objective Objective To evaluate the efficacy of Heqi San combined with metformin in the treatment of obese polycystic ovary syndrome (PCOS). Methods A total of 60 patients with obese polycystic ovary syndrome who met the inclusion criteria were randomly divided into 2 groups, 30 patients in each group. The control group was treated with metformin, and the treatment group was treated with Heqi San on the basis of the control group. Both groups were treated for 3 months. The FPG was determined by glucose oxidase method, and fasting insulin (FINS), TC, TG, LDL-C, HDL-C level were measured by radio immunoassay, and the insulin resistance index (IR) was measured by the method of HOMA-IR. The luteotropic hormone (LH), pro follicle stimulating hormone (FSH) and testosterone (T) were detected by the automatic electrochemical light detector, and the ratio of LH/FSH was calculated. The ovarian volume and body mass index changes and clinical effect were evaluated. Results After treatment, the BMI (20.09 ± 3.12 kg/cm2 vs. 23.39 ± 1.43 kg/cm2, t=6.889), FPG (4.44 ± 0.17 mmol/L vs. 4.74 ± 0.16 mmol/L, t=6.945), FINS (10.69 ± 2.41 IU/L vs. 16.29 ± 5.95 IU/L, t=4.778), TC (3.91 ± 0.50 mmol/L vs. 4.20 ± 0.39 mmol/L, t=2.505), LDL-C (2.64 ± 0.63 mmol/L vs. 3.18 ± 0.62 mmol/L, t=3.346), LH (8.70 ± 2.44 U/L vs. 10.27 ± 2.69 U/L, t=2.934), the ratio of LH/FSH (1.33 ± 0.58 vs. 2.18 ± 0.56, t=5.775), T (1.73 ± 0.74 nmol/L vs. 2.95 ± 1.10 nmol/L, t=5.040) and ovarian volume (12.61 ± 2.29 mm3 vs. 14.26 ± 2.52 mm3, t=6.982) in the treatment group were significantly lower than those in the control group (P<0.01 or P<0.05). The FSH (7.33 ± 2.28 U/L vs. 5.95 ± 1.20 U/L, t=2.934) in the treatment group were significantly higher than those in the control group (P<0.05). The total effective rate in the treatment group was 83.3% (25/30) and 63.3% (19/30) in the control group. The difference between the 2 groups was statistically significant (χ2=3.068, P=0.050). Conclusions The Heqi San combined with metformin can effectively improve the body mass index, glucose metabolism, lipid metabolism index and sex hormone level, and reduce the volume of ovary in patients with PCOS, and the curative effect is better than that of oral metformin alone.

Many studies have proven that arsenic trioxide (As2 O3 )as a single agent is not effective against hepatocellular carcinoma (HCC).Many scholars believe that chemotherapy drug resistance of HCC to As2 O3 is the most important reason.The underlying drug resistance mechanism of HCC cells to As2 O3 remains unclear.Studies show that potential mechanism may be tightly associated with As2 O3 pharmacokinetics and properties of HCC tissues and complex molecular biology.
