Objective To explore the causes and risk factors affecting early death in patients with traumatic cervical spinal cord injury (SCI). Methods Clinical data of 553 patients with traumatic cervical SCI were analyzed retrospectively to discuss the related factors affecting early death of patients with traumatic cervical SCI by using univariate analysis and multivariate logistic regression analysis. Results The early mortality of the patients with traumatic cervical SCI was 4.0% ( 22/553 ). The main causes of the early death were respiratory failure in nine patients (40.9%) and electrolyte disorders in five (22.7%). Univariate analysis showed that age, cervical spinal cord injury severity, complications in respiratory, cardiovascular, digestive systems and electrolyte disturbance as well as tracheotomy were considered statistically significant for early death in patients with traumatic cervical SCI ( P < 0, 05 ). Multivariate logistic regression analysis showed that age, cervical SCI severity, complications in respiratory,cardiovascular system and electrolyte disturbance as well as tracheotomy. Conclusion Severe cervical SCI, combined respiratory, cardiovascular system and electrolyte disorder complications as well as tracheotomy are high risk factors for the early death in patients with traumatic cervical SCI.

Hematoma enlargement is a common harmful event after cerebral hemorrhage, which can lead to deterioration of neurological function and poor outcome. Early detection of high-risk patients can help prevent hematoma enlargement and improve the outcome of patients. Although the exact mechanism of hematoma enlargement is unclear, more and more evidence shows that many imaging signs may be related to hematoma enlargement, such as dot sign, mixed sign, black hole sign, island sign, etc. This article mainly reviews the relevant imaging prediction factors of hematoma enlargement from the perspective of imaging.

ObjectiveTo investigate the characteristics of traumatic spinal cord injury (TSCI) urban inpatients of Tianjin in 2007. MethodsInpatients with TSCI of 8 hospitals in Tianjin in 2007 were reviewed. ResultsThere were 73 patients in total. Mean age was (51.34±14.597) years. Male∶Female was 3.56∶1. Falling, motor vehicle accidents （MVC） were the main causes of TSCI. The cervical spinal cord injuries were predominant. 26% were complete injury and 74% were incomplete. 6 cases were dead. Patients with ASIA grade D recover well.

This paper summarizes the factors affecting schistosomiasis transmission in the middle and lower reaches of the Yangtze River before and after the completion of the Three Gorges Dam and analyzes schistosomiasis prevalence trends to provide a basis for the application of the Three Gorges project methodologies in other areas.The Three Gorges Dam has demonstrated a positive effect on schistosomiasis control.Hubei,Hunan,Jiangxi,Anhui,and Jiangsu in the middle and lower reaches of the Yangtze River are currently regions with a high prevalence of schistosomiasis.These five provinces contained 97.62％ of known snail areas and 93.66％ of calculated schistosomiasis cases with 90.07％ of counties (cities,districts) not yet meeting the criteria for schistosomiasis transmission interruption by the end of 2016.After the Three Gorges Dam was built,the prevalence of schistosomiasis in the middle and lower reaches of the Yangtze River decreased.By the end of 2016,the estimated number of cases decreased by 92.75％ and the snail habitat areas decreased by 6.56％ compared to 2004.No acute schistosomiasis cases have occurred for two consecutive years since 2015.

OBJECTIVETo observe the effect of N-acetylcysteine (NAC) on intestine injury induced by cardiopulmonary bypass (CPB) in rats.

METHODSThirty-two rats were randomly divided into sham-operated group, NAC control group, CPB model group, and CPB plus NAC treatment group (n=8). In the latter two groups, the rats were subjected to CPB for 1 h. The rats received intraperitoneal injections of normal saline or NAC (0.5 g/kg) as appropriate for 3 successive days prior to CPB, and those in CPB plus NAC group were given NAC (100 mg/kg) in CPB prime followed by infusion at 20 mgsol;(kg·h) until the cessation of CPB. Intestinal and blood samples were collected 2 h after CPB for pathological analysis and measurement of intestinal concentrations of malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interlukin (IL)-6 and activity of superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-Px) and serum levels of diamine oxidase (DAO).

RESULTSEvident oxidative stress and pathological damages of the intestines were observed in rats after CPB. NAC treatment obviously alleviated intestinal damages induced by CPB, decreased the levels of intestinal MDA, TNF-α, IL-6 and serum DAO and increased activity of SOD, GSH, and GSH-Px in the intestines.

CONCLUSIONPerioperative NAC treatment can alleviate intestinal injury induced by CPB in rats by suppressing oxidative stress and inflammatory response.

Traditional Chinese medicine holds that chemotherapy drugs belong to “medicinal toxins”， which are fierce in nature， and while killing tumor cells， they also damage human vitality， firstly disturbing spleen and stomach functions. Based on LI Gao's theory that “fire and original qi are restricted to each other， and one wins while the other loses”， it is believed that the balance between fire and original qi is the guarantee to maintain the material and energy metabolism of the body. As the driving force of human life activities， original qi is the “yang qi” that dominates the qi of the whole body. When the function of spleen and stomach is impaired， and the replenishment of acquired source is insufficient， there will be deficiency of yang qi and hyperactivity of yin fire， manifested as various adverse reactions of the body after chemotherapy. Following the treatment principle of tonifying the spleen and stomach and lifting yang qi， it is recommended to use sweet and warm medicinals to remove heat， and take formulas such as Buzhong Yiqi Decoction （补中益气汤） and Danggui Buxue Decoction （当归补血汤） to treat various post-chemotherapy adverse reactions mainly manifested as fire pathogen damaging fluid and consuming qi， yin deficiency and fire exuberance， alleviate related symptoms， which can not only ensure adequate chemotherapy cycle， but also improve the anti-tumor effect， and improve the quality of life of patients.

Objective To detect the change of the anti-S. japonicum antibody level after people migrated from outside embankment to newly established town. Methods Three pilot spots were established for the investigation: one spot thut both inhabitancy and cultivation disused (A), one spot that only inhabitancy disused but farming continued (B) and the third one served as control (C). DIGFA and ELISA were used to detect the antibody level in the populations from 2002 to 2005. Results The positive rate of anti-S.japonkum antibody declined significantly from 6.63% to 3.52% by DIGFA and from 7.26% to 3.71% by ELISA at spot A (X2=5.2625, P

Esophageal cancer is a common malignant tumor of the digestive tract. At present， the pathogenesis of esophageal cancer has not been fully clarified. Although surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy have achieved good clinical results in the treatment of esophageal cancer， there are still many complications and severe adverse reactions. As an important part of traditional Chinese medicine （TCM）， in recent years， many basic experiments and clinical studies have proved that Chinese medicine has a good effect in treating esophageal cancer. At the same time， the multi-component and multi-target characteristics of Chinese medicine and unclear pathogenesis of esophageal cancer determine that there are some problems such as unclear mechanisms of Chinese medicine in preventing and treating esophageal cancer. It is necessary to start with modern medicine and reveal the mechanism of Chinese medicine in preventing and treating diseases from the aspects of molecular biology and network pharmacology. It is believed in TCM that the occurrence of esophageal cancer is mostly attributed to stagnation of liver Qi， phlegm stasis and Qi stagnation， fluid consumption and heat accumulation， the decline of healthy Qi， and the cementation of cancer toxicity. According to the literature review， Chinese medicinal compounds mainly include tonic formulae （such as Liu Junzitang）， drying and moistening formulas （such as Qigesan）， and heat-clearing formulas （such as Fufang Kushen injection）. Chinese medicinal monomers mainly include drugs potent in attacking poison and killing insects， clearing heat， activating blood and resolving stasis， and regulating Qi， which is consistent with the etiology and pathogenesis of esophageal cancer in TCM. It is also found that Chinese medicine can promote cell apoptosis and autophagy， block cell cycle， and reverse cell resistance by regulating phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， neurogenic locus notch homolog protein （Notch）， Wnt/β-catenin， mitogen-activated protein kinase （MAPK）， nuclear factor-κB （NF-κB）， Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3）， and other related signaling pathways， but there is no systematic summary. This study systematically summarized the relevant signaling pathways of Chinese medicine in regulating esophageal cancer， which is helpful to clarify the relevant mechanisms of Chinese medicine in the process of esophageal cancer occurrence， development， invasion， and metastasis， so as to provide new targets and new perspectives for the treatment of esophageal cancer and promote the modernization of TCM.
