OBJECTIVETo explore the association between C825T polymorphism of G protein beta3 subunit (GNB3) gene and different Hilit types of essential hypertension (EH) in the Uygur nationality of Xinjiang.

METHODSAccording to Uygur medical theories, EH patients (as the EH group) and non-EH patients (as the control group) were assigned to four Hilit groups. The C825T polymorphism of GNB3 was detected in 161 EH patients and 379 non-EH subjects of different Hilit types by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to explore the difference of the genotypes and allelic frequencies and hypertension.

RESULTS(1) In Xinjiang Uygur population, the distribution frequencies of GNB3 C825T polymorphism were in accordance with Hardy-Weinberg (chi2 = 0.871, P = 0.647). (2) There was no statistical difference in the distribution frequencies of three genotypes and two alleles of GNB3 between the EH group and the control group (P > 0.05). (3) There was statistical difference in distribution frequencies of three genotypes between the abnormal Sapra and non-abnormal Sapra group (the sum of abnormal Sewda, abnormal Kan, and abnormal Balhem) (chi2 = 6.905, P = 0.032), especially between the abnormal Sapra and abnormal Balhem groups (chi2 = 10.404, P = 0.006), but there was no statistical difference in distribution frequencies of alleles between the two groups (P > 0.05). (4) In 161 EH patients, there was statistical difference in the distribution frequencies of three genotypes and two alleles between the abnormal Sapra and non-abnormal Sapra group (chi2 = 9.034, P = 0.011; chi2 = 4.701, P = 0.03).

CONCLUSIONSBoth TT genotype and T allele of GNB3 C825T polymorphism might not be associated with EH patients in Xinjiang Uygur populations. However, they were correlated with hypertension patients of non-abnormal Sapra, indicating the pathogeneses of EH with different Hilit types might be different.

For securing large, giant, and wide-neck aneurysms, conventional coil embolization has substantial limitations, such as incomplete occlusion, recanalization, and a high recurrence rate. To overcome these limitations, a novel paradigm was suggested and, as a result, flow-diverting device was developed. The flow-diverting device is an innovative and effective technique to allow securing of large, giant, and wide-neck aneurysms. In numerous studies, the flow-diverting device has shown better outcomes than coil embolization. However, the flow-diverting device has also some risks, including rupture of aneurysm, intracerebral hemorrhage, and ischemic stroke. In addition, with more experience, unexpected complications are also reported.5) 7) In the present case, we experienced a delayed ischemic stroke at 27 days after endovascular treatment. The patient had multiple aneurysms and, among them, we treated a large posterior communicating artery aneurysm using Pipeline™ Embolization Device. The patient was tolerable for 25 days, but then suddenly presented intermittent right hemiparesis. In the initial diffusion magnetic resonance imaging (MRI), there was no acute lesion; however, in the follow-up MRI, an acute ischemic stroke was found in the territory of anterior choroidal artery which was covered by Pipeline Embolization Device. We suspect that neo-intimal overgrowth or a tiny thrombus have led to this delayed complication. Through our case, we learned that the neurosurgeon should be aware of the possibility of delayed ischemic stroke after flow diversion, as well as, long-term close observation and follow-up angiography are necessary even in the event of no acute complications.

Objective To investigate the expression level of Gas6 in patients with Immune Thrombocytopenia (ITP) and its clinical significance.Methods The experimental group was peripheral blood samples collected from 35 cases diagnosed with ITP in hematology department of Changhai Hospital in Shanghai from October 2013 to December 2015.Control group was peripheral blood from 35 healthy examined individuals at the same time.After separating plasm from the two group samples,the protein level of Gas6,IFN-α,IL-4,IFN-γ and IL-17 were measured by Enzyme-linked immunosorbent assay (ELISA),comparison of expressional level of the two groups was measured by t test.Pearson correlation analysis was used to decide the relation between Gas6 and cytokines such as IFN-α.Results The expression level of Gas6 in experimental and control groups was 27.28±7.56 ng/ml vs 20.51±5.39 ng/ml (t=4.314,P＜0.000 1);IFN-γ was 221.67±57.64 pg/ml vs 45.32 ±16.79 pg/ml (t=17.38,P＜0.000 1);IL-4 was 113.86±26.48 pg/ml vs 49.87±14.98 pg/ml (t=12.44,P＜0.000 1);IL-17 was 168.96±47.88 pg/ml vs 109.56±28.97 pg/ml (t=6.28,P＜0.000 1);IFN-α was 34.83±8.12 pg/ml vs 29.89 ± 5.76 pg/ml (t=2.936,P=0.004 5),all with statistical differences (P＜0.05).Pearson analysis showed that Gas6 was positively related with IL-17,IL-4,IFN γ (r=0.564,0.486,0.449,P＜0.05) and there was difference statistically,but Gas6 was not correlated with IFN-α.Conclusion Gas6 may participate in the disease formation of ITP through affection on cytokines secreted by Th cell subsets,and it was the potential therapeutic and predicted target for this disease clinically.

Children's food behaviors have been expressed in a various ways because of recent changes in their family environment. Thus, this study was performed to investigate in-depth qualitative research on the mother's perception on children's food behaviors by focused group interview. This study was designed in four steps of planning, collection of participants, process, and analysis. Participants for the focus group interview were recruited and sampled from households with elementary school students in the Seoul and Gyeonggido areas. Groups were divided by total income and education expense levels. 1) High income household: It is better to improve currently existing web sites for nutrition education. 2) Mid income household: Easy, practical, and inexpensive off-line cooking class/nutrition education classes for mothers are needed. Nutrition programs for children should be developed through mass media and be promoted in the broadcasting circle. 3) Low income household: Motivation is required for mothers' education and the serious nutritional problems of children should be informed through mass media and home correspondence from school. And interesting educational materials should be developed for children to read whenever they want.

OBJECTIVETo study the effects of long-term exposure to carbon disulfide (SC(2)) on cardiovascular system of workers.

METHODSThe concentrations of CS(2) were detected in the representative workshops with different exposure levels. The indicators related to cardiovascular system were tested in 633 workers occupationally exposed to CS(2), which included blood pressure, electrocardiogram, blood routine (blood RT), cholesterol (TCHO), triglyceride (TG) and so on. The data were analyzed by chi-square test and multiple logistic regression analysis.

RESULTSThe exposure concentration of CS(2) for 389 workers was less than or equal to 5 mg/m(3), which for other 244 workers was higher than 5 mg/m(3). The maximum exposure concentration of CS(2) was 15.73 mg/m(3). There were no significant effects of CS(2) on the electrocardiogram, red blood cells, white blood cells, blood platelet, TCHO and TG of workers. However, the positive effects of CS(2) on blood pressure and negative effects of CS(2) on hemoglobin were found. The rates of high TCHO, TG and hypertension in male workers were significantly higher than those in female workers (P < 0.05). The rates of high TCHO, hypertension and sinus arrhythmia in older workers (≤ 30 years old) were significantly higher than those in young workers (> 30 years old) (P < 0.05). The rate of sinus arrhythmia in workers with 1 - 10 working years was significantly higher than that in workers with more than 10 working years (P < 0.05). The rate of hypertension in workers with 1 - 10 working years was significantly lower than that in workers with more than 10 working years (P < 0.05).

CONCLUSIONThere were no significant effects of CS(2) exposure on the indexes of cardiovascular system of workers.

Objective To evaluate the value of serum CEA and CA19-9 concentration for clinical staging of colorectal cancer. Methods A total of 350 patients who underwent the surgical treatments for colorectal cancer between February 2015 to January 2017 were enrolled. The serum CEA and CA19-9 were detected by chemoluminescence method. Results The positive rate of CEA of patients in stageⅠto Ⅳ was 25.00%, 36.69%, 50.78% and 66.67%, respectively. The positive rate of CA19-9 of patients in stageⅠto Ⅳwas 2.94%, 10.07%, 17.97% and 53.33%, respectively. The positive rates of CEA and CA19-9 were gradually increased with the stage developing (P<0.05). Results from multivariate logistic regression analysis showed that the positive levels of CEA and CA19-9 were risk factors in the TNM staging of colorectal cancer. The ORs and 95%CI were 1.790 (1.163-2.755)and 3.476(1.790-6.749), respectively. Conclusion The positive serum concentrations of CEA and CA19-9 showed significant associations with TNM staging. Preoperative serum concentrations of CEA and CA 19-9 could be auxiliary diagnostic indicators to assess the condition of colorectal cancer.

Conclusion The experimental results show that the concentration of standard substance has a great influence on the measurement process, so it is necessary to standardize the dilution process and simplify the dilution procedure to improve the accuracy of measurement results.

Objective To investigate the occurrence and reporting of sharp injuries among health care workers (HCWs)at all levels of hospitals in Xuzhou City,provide evidences for formulating protective measures against sharp injuries and improving the reporting system.Methods From July to August 2016,13 hospitals in Xuzhou City were randomly selected by multi-stage stratified random sampling method,the general information,occurrence of sharp injuries,and reporting situation was performed questionnaire survey.Results A total of 2 694 valid question-naires were collected,incidence,case incidence,and reporting rate of sharp injuries were 10.32%,12.84%,and 30.64% respectively.Case incidence of sharp injuries among HCWs in primary,secondary,and tertiary hospitals were 44.83%,11.53%,and 12.52% respectively,case incidences of sharp injuries in different levels of hospitals were significantly different (χ2＝55.148,P＜0.001).The main opportunity for sharp injuries was when HCWs re-turned needle cap (79 cases,22.83%),the main device involving sharp injuries was hollow-bore needle (297 cases, 85.84%).Incidences of sharp injuries among HCWs receiving different training were significantly different (χ2＝66.760,P＜0.001).Conclusion Current situation of sharp injuries among HCWs in this region is not optimistic, there are some problems such as poor training efficacy,low reporting rate and low use rate of safety devices,effec-tive measures should be taken to establish an effective monitoring and tracking system for sharp injuries,so as to re-duce the occurrence of sharp injuries.

Autophagy is a self-decomposing process that is used to degrade long-lived proteins or necrotic organelles.It is extremely dependent on lysosomes,widely present in eukaryotic cells and highly conserved.Autophagy can protect the cells themselves and help them resist the adverse environment at a proper level,but excessive autophagy can result in autophagic cell death.In recent years,with the comprehensive research of autophagy,it has been found that autophagy is closely related to the development and progression of most tumors.More drugs associated with autophagy are used for the clinical treatment of tumors,but they have different therapeutic effects on different tumors,so the impact of autophagy-related drugs on normal cells need to be identified through more clinical trials and experimental studies.This paper reviews the roles of autophagy in the occurrence and development of tumors,and recent progress in the treatment of cancer by regulating autophagy through drugs.

The combination of pungent-warm medicinal has experience 3 changing processes during initial stage of warm diseases:simply using pungent-warm medicinal,combination of pungent-warm with bitter-cold medicinal and combination of pungent-warm with pungent-cool medicinal.There were 3 important periods during the formation of warm disease school, which were infancy stage(period from Warring States to Jin and Tang Dynasties),growth stage(periods of Song,Jin and Yuan Dynasties)and forming stage(periods of Ming and Qing Dynasties).With the deuolopment of warm disease school, the use of pungent-warm medicinal altered from hot to slight warm, and proportion of pungent-warm medicinal and cold-cool medicinal changed continuously.The combination administration of pungent-warm and cold-cool medicinal for treating febrile diseases at the initial stage was summed up,clinical prescribing according to pathogenesis was emphasized,and thinking train of property-flavor combination was stressed.The combi-nation of pungent-warm and cold-cool medicinal aimed at releasing depression and eliminating pathogen combined with clearing heat,cooling and dispelling pathogen at the initial stage of warm diseases.The selection and dosage of medicinal should be determined according to the degree of depression of qi move -ment and intense heat toxin.The thought of combination of pungent-warm and cold-cool medicinal should be thought of when practicing and treating warm diseases in chinic.
