AIM: To explore the clinical significance of Krüpple-like factor 15 (KLF15) protein expression in the patients with lung adenocarcinoma for exploring the therapeutic and prognositic biomarkers of lung cancer.ME-THODS: Four cases of lung adenocarcinoma tissues and matched adjacent tissues were collected from our hospital, and the expression of KLF15 protein in these tissues was analyzed by Western blot.At the same time, 72 cases of archived paraffin-embedded samples and clinical data of the patients with lung adenocarcinoma were also collected.The KLF15 protein expression in the archived paraffin-embedded lung adenocarcinoma samples was detected by immunohistochemical staining.The correlations between KLF15 protein expression and clinical characteristics of the patients including prognosis were also analyzed.In addition, the KLF15 protein was up-regulated in A549 cells, and then the effects of KLF15 protein on the viability of the cells were measured by CCK-8 assay.RESULTS: The protein expression of KLF15 in the 4 cases of lung adenocarcinoma tissues was significantly lower than that in matched paracancerous tissues.Fifty-three cases of lung adenocarcinoma specimens showed low expression or no expression of KLF15 protein in total 72 cases (73.6%).The 5-year survival rate of the patients with high expression of KLF15 protein in their specimens was higher than that of the patients with the low expression of KLF15 protein (P<0.01), and the expression of KLF15 protein was significantly correlated with the pathological staging (P<0.01) and T stage (P<0.01) of the patients with lung adenocarcinoma.Furthermore, the low expression of KLF15 protein was an important poor prognostic indicator of the patients.Up-regulation of KLF15 protein in the A549 cells significantly inhibited the growth of the cells.CONCLUSION: KLF15 inhibits the growth of lung adenocarcinoma cells.It could be used as a therapeutic target and a prognostic biomarker for the patients with lung adenocarcinoma.

OBJECTIVE:To explore and analyze signals of Xiyanping injection-induced urticaria from spontaneous reporting system database of Jiangxi province. METHODS:The continuous ADR report monitoring data were collected from spontaneous re-porting system of Jiangxi province,and established database. Bayesian confidence propagation neural network(BCPNN) method was used to calculate information component,IC value of Xiyanping injection-induced urticaria. The year-to-year changes of IC val-ue and its interval were analyzed. RESULTS:A total of 328324 ADR reports were collected in Jiangxi province during 2004-2016. The IC value of Xiyanping injection-induced urticaria detected by BCPNN method was 1.10(the lower limit of IC value was 0.65, and upper limit was 1.54),i.e. there was signal and the IC value ranged from-0.87 to 1.65. CONCLUSIONS:The results of BCPNN method suggest that urticaria is a warning signal of Xiyanping injection. The risk is increasing gradually,and prediction precision increase with the addition of report quantity.

Objective To detect the plasma level of tissue factor (TF) in non-small cell lung cancer (NSCLC) patients,and to discuss its association with hypercoagulation,venous thromboembolism and prognosis of lung cancer.Methods Sixty-one impatients in our hospital with confirmed lung cancer were enrolled as the study group.Thirteen patients with benign pulmonary diseases and 14 healthy volunteers were selected as the control groups.Bseline and follow-up clinical data were collected from participants.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of TF in plasma of all subjects.Results The levels of TF in plasma from NSCLC patients and participants with benign pulmonary diseases was significantly higher than that in healthy controls((550.88 ± 201.58) ng/L vs (510.77 ± 201.20) ng/L vs (178.34 ±66.73) ng/L,P ＜0.05).According to the plasma levels of TF,which have been detected in all subjects,the patients were divided into two groups:low level group (range from 103.73 ng/L to 476.22 ng/L) and high level group (range from 476.221 ng/L to 1003.00 ng/L).Statistical analysis showed that there was a positive correlation between plasma TF levels and TNM stages in NSCLC patients (P =0.026).Patient with metastasis had a higher plasma TF level than other patients (P =0.020).The log-rank test revealed that there was no significant difference in survival between the high level group and low level group (x2 =0.145,P =0.704).Multivariate Cox proportional hazards regression analysis indicated that plasma TF levels did not predicted for death(RR =1.001,95％CI0.998-1.004,P=0.452).Conclusion The plasma TF level in NSCLC patients was correlated with TNM stages;it had no significant relationship with hypercoagulation state and survival rate in NSCLC patients.Limitations should be aware of while evaluating the clinical course and prediction of prognosis of NSCLC patients using plasma TF levels.

OBJECTIVE:To investigate general regularity and characteristics of tetanus antitoxin (TAT) induced by ADRs,in order to provide reference for rational drug use in the clinic.METHODS:Domestic and foreign literatures on ADRs induced by TAT were retrieved,and related information of 2 636 case of ADR were analyzed statistically.RESULTS:Among patients whose gender and age were recorded,male with ADR induced by TAT was more than female,mainly aged 15-35 years old,accounting for 70.32 ％ (289/411);28.28 ％ (56/198) used water for injection;ADR occurred within 30 min after medication in 5.84％ (154/2 636)cases;main ADR were lesion of skin and its appendents,circulatory system damage,systemic reaction damage.Main clinical manifestations were urticaria,rash,chest tightness and anaphylaetic shock,etc.Ten cases died and 7 cases had sequelae;the rest were all recovered and cured after symptomatic treatment.CONCLUSIONS:TAT has a higher proportion of allergic reactions,especially anaphylactic shock,but great importance should be attached to rare auditory and vestibular dysfunction,visual impairment,elevated white blood cell count and other ADR.It is suggested to strengthen medication monitoring and used drugs strictly in accordance with drug package inserts so as to promote rational drug use.

Objective To make analysis and diagnosis on backhand twist technique used by player A, who is the leading men’s player of national table tennis team, so as to provide references for improving his backhand twist technique. Methods The three-dimensional kinematics test and analysis were used. The backhand twist techniques of player A and those of player B who has good backhand twist techniques were compared by quantitative data and picture analysis. Results At the stage of swinging racket backward, the racket swing amplitude, shoulder angle and wrist angle of player A were significantly smaller than those of player B. The roll angle of trunk of player A was significantly larger than that of player B. At the stage of swinging and hitting the ball, the shoulder angle, elbow angle of player A were significantly bigger than those of player B, while the increasing amplitude of shoulder angle and elbow angle, as well as the changing amplitude in roll angle of trunk of Lin Guoyuan were significantly smaller than those of player B. At the stage of swinging racket forward, the shoulder angle and elbow angle of player A were significantly bigger than those of player B. The increasing amplitude of shoulder angle and elbow angle, as well as the roll angle of trunk and its changing amplitude of player A were significantly smaller than those of player B. Conclusions The racket swing amplitude of player A was smaller, and the distance between the racket and the ball of player A was close at the end of swinging racket backward stage. During swinging and hitting the ball stage, the hitting point was far from the body, the shoulder joint was not stable enough to support, so that the wrist was used more. The center of gravity was not enough to force forward, and the outburst power was not concentrated. At swinging racket forward stage, player A’s braking was not active enough, which affected the stability of hitting the ball. At hitting the ball stage, the torsion of the trunk was smaller, and the waist power was not concentrated. On the basis of unaffecting the forehand outburst power, player A should slightly adjust his backhand twisting technique, or appropriately increase the the racket swing amplitude and torsion of the body. In the process of hitting the ball, the sequence of outburst power was the waist, the forearm and the wrist.

Objective To study the relationship between socioeconomic status (SES) and esophageal squamous cell carcinoma(ESCC) in Taixing city,Jiangsu province.Methods A populationbased case-control study was carried out to collect data including demography,socioeconomic status indicators and possible risk factors.Unconditional logistic regression was used to compare different SES indicators and composite wealth scores constructed between cases and controls,using the principal component analysis methodology.Results Factors as:having received high school or higher education (OR=0.66,95％CI:0.46-0.96),living space over 67 m2 per-capita (OR=0.71,95％CI:0.54-0.94),drinking tap water longer than 5 years (OR=0.76,95％ CI:0.59-0.98) and wealth score ＞0.93 (OR=0.63,95％CI:0.48-0.83) were associated with increased risk of ESCC.Compared to those worked in farming,forestry,animal husbandry,fishery and water conservancy,the individuals who worked in business-service industry were at lower risk of ESCC (OR =0.65,95％CI:0.43-0.97).Conclusion An inverse association of low SES and ESCC were found in Taixing people that called for further explanation.

Chinese president Xi Jinping made clear at the National Health and Wellness Conference that health is the prerequisite for people's all-around development and a precondition for the sustainable development of China. Oral health is an indispensable component of overall health in humans. However, the long neglect of oral health in overall health agendas has made oral diseases an increasing concern. With this perspective, we described the global challenges of oral diseases, with an emphasis on the challenges faced by China. We also described and analyzed the recently released health policies of the Chinese government, which aim to guide mid-term and long-term oral health promotion in China. More importantly, we called for specific actions to fulfill the larger goal of oral health for the nation. The implementation of primordial prevention efforts against oral diseases, the integration of oral health into the promotion of overall health, and the management of oral diseases in conjunction with other chronic non-communicable diseases with shared risk factors were highly recommended. In addition, we suggested the reform of standard clinical residency training, the development of domestic manufacturing of dental equipment and materials, the revitalization traditional Chinese medicine for the prevention and treatment of oral diseases, and integration of oral health promotion into the Belt and Road Initiative. We look forward to seeing a joint effort from all aspects of the society to fulfill the goal of Healthy China 2030 and ensure the oral health of the nation.
