OBJECTIVE:To provide reference for health service support at high altitude area. METHODS:375 servicemen who rapidly entered high altitude area were investigated by questionnaire in 2013 to investigate the compliance of using high alti-tude special medicines and incidence of mountain sickness and analyze its correlation. RESULTS:375 questionnaires were distribut-ed and 324 questionnaires were collected with effective response rate of 86.4%. The utilization rate of Multivitamin tablet,Skin cream and Lip balm for high altitude area were 30.9%,13.3% and 40.1% respectively. The compliance of using high altitude spe-cial medicines had effect on the incidence of related mountain sickness. The incidence of mountain sickness of people who followed the physician’s instructions was significantly lower than those who did not. The difference was statistically significant(P<0.05). CONCLUSIONS:High altitude special medicines can relieve and prevent the mountain sickness. But the overall compliance of us-ing high altitude special medicines was not ideal. The education of high altitude special medicines should be strengthened,and dos-age forms and medicine instruction should be enhanced to improve its compliance and play better protective effect.

Objective To assess the effectiveness and safety of heat moisture exchangers (HMEs) on the artificial airway humid-ification in the mechanically ventilated patients .Methods The related literature in the Cochrane Library ,PubMed ,Embase ,CNKI , VIP ,WanFang database and CBM from the establishment to March 2012 were retrieved ,then included the randomized controlled trial(RCT) and quasi-RCT on the effect of HMEs for the artificial airway humidification in the mechanically ventilated patients were performed the meta analysis by using RevMan 5 .1 .2 software .Results 19 RCT were included(involving 2 960 patients) , which were the random parallel controlled trials .The meta analysis results showed that HMEs could not reduce the incidence rate of ventilator-associated pneumonia(VAP)(RR=0 .78 ,95% CI 0 .61-1 .01 ,P=0 .06) ,also could not decrease the hospitalization mor-tality(RR=0 .94 ,95% CI 0 .83-1 .08 ,P=0 .40) ,the length of ICU stay(MD= -0 .32 ,95% CI -3 .13 -2 .50 ,P=0 .82) and the occurrence rate of catheter occlusion (RR=0 .65 ,95% CI 0 .22 -1 .93 ,P= 0 .44) ,the differences between the two groups had no statistical significance .But 5 RCT reported that using HMEs could reduce the patient′s costs .Conclusion HMEs can not reduce the incidence rate of VAP ,mortality ,length of ICU stay ,occurrence rate of airway occlusion ,but can cut down the patient′s cost . Due to the risk of bias existing in all included RCT and the low quality of the obtained evidences ,more strictly designed and imple-mented RCTs are needed to further verify thse evidences .

Harmful substances are produced during the metabolism of alcohol in the human body, which causes liver disease.The mechanism of oxidative stress is the main pathogenesis of alcoholic liver disease, which plays a major role in the occurrence and development of alcoholic liver disease.Alcohol-induced oxidative stress mediated by reactive oxygen species(ROS)/reactive nitrogen species(RNS) brings about liver disease via apoptotic signaling pathway and MAPK signaling pathway, and alleviates liver disease through Nrf2 signaling pathway.In this paper, the studies on the mechanism of oxidative stress in alcoholic liver disease are reviewed.

Reactive oxygen species (ROS) is defined as the electron reduction product of oxygen with high reactivity which can maintain normal physiological functions and redox homeostasis. The tumor microenvironment is in a state of oxidative stress. ROS can affect multiple processes of tumor immune response by modulating the phenotype and functions of tumor cells and immune cells. With the rapid development of immunology, ROS-based tumor immunomodulation has been widely concerned and studied. In this review, the mechanism of ROS participating in tumor immune response is elaborated. Meanwhile, the research process and application of ROS in tumor immunomodulation in recent years are reviewed and analyzed.

Objective:To evaluate the effect of vacuum disk(VD) for non-invasive treatment of recurrent and acquired pectus excavatum(PE).Methods:From June 2017 to June 2019, 29 patients recruited from our outpatient clinic were included in this retrospective study and followed-up every 3 month according to the schedule. The patients were distributed into three groups(group 1 treated ≤6 months; group 2 treated from 6 months to 12 months; group 3 treated >12 months). The device should be applied regularly for more than 2 hours daily. The deformity chest wall was scanned by three-dimensional(3D)scanner at clinic, and the 3D-depth(3D-DE) and 3D-Haller index(3D-HI) of PE were calculated through Geomagic software.Results:In this cohort, 29 patients were eligible, 18 symmetrical PE and 11 asymmetric PE. The application time ranged from 3 months to 15 months(average 7.6 months). 4 paitents was lifted to a normal level, 23 patients were differently improved. However, 2 paitents had no improvement. The average of the depth and 3D-HI of all patients were improved from 17.7 mm to 11.6 mm and 1.739 to 1.598, respectively. It’s no statistically significant difference for the elevation of 3D-DE and 3D-HI between symmetrical and asymmetric PE( t=-2.821, P=0.558; t=0.074, P=0.068). When comparing the improvement of 3D-DE or 3D-HI of PE to the patient's treatment time, a statistically significant difference was proved between the group 2 and group 1( t=-2.261, P=0.014; t=-0.436, P=0.043), but not between the group 3 and group 2( t=-1.240, P=0.139; t=0.622, P=0.568). The main side effects include moderate subcutaneous hematoma(84%), petechial bleeding(27%), thoracalgia(32%) and chest tightness(17%), no other side effect appear till now. Conclusion:VD for treatment of recurrent and acquired PE is convenient, safe and noninvasive, which can be an alternative treatment for recurrent and acquired PE, However, long term of efficacy evaluation is still needed.

Objective: To explore the mechanism of acupuncture in regulating cognitive deficits in insomnia rats by observing the effect of acupuncture on microglia in thalamic reticular nucleus (TRN). Methods: Thirty rats were randomly divided into a control group, a model group and an acupuncture group, with 10 rats in each group. The insomnia model was established by intraperitoneal injection of para-chlorophenylalanine (PCPA) once a day for 2 d. Rats in the control group were intraperitoneally injected with the same amount of normal saline. Rats in the acupuncture group received acupuncture at Neiguan (PC 6) and Zusanli (ST 36) for 5 consecutive days. The CLOCKLAB 2 data acquisition system was used to dynamically observe the sleep of the rats throughout the experiment. The cognition of rats was evaluated by event-related potentials (ERPs). After intervention, brain tissue was extracted. Immunofluorescence was used to test the fluorescence expression in TRN region. The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. Results: After intraperitoneal injection of PCPA suspension, the spontaneous activity in light period of rats in the model group and acupuncture group increased significantly compared with the control group (both P<0.01). After acupuncture treatment, the rats in the acupuncture group had much less spontaneous activity during the light period than those in the model group (P<0.01), and the results indicated that acupuncture could effectively improve the sleep quality of insomnia rats. Compared with the control group, rats in the model group showed that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α increased significantly (all P<0.05), and the P3 amplitude decreased significantly (P<0.01). Compared with the model group, rats in the acupuncture group presented that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α were significantly decreased (all P<0.05), and the amplitude of P3 was significantly increased (P<0.05). Conclusion: Acupuncture possesses an ability to improve the cognitive state in insomnia rats. The mechanism may be related to inhibiting the microglial activation, diminishing the levels of pro-inflammatory mediators like IL-1β and TNF-α, and promoting the recovery of central nervous system function.

To develop a core-shell structure pDNA-CaPi-PLGA nanoparticles (CS-pDNA-CaPi-PLGA-NPs), calcium phosphate-pDNA nano complexes (CaPi-pDNA) were encapsulated inside of PLGA shells. The characteristics of the nanoparticles, including morphology, average particle size, zeta potential, entrapment efficiency, loading efficiency, stability in medium, pDNA protection ability from nuclease degradation, in vitro release, cytotoxicity and cell transfection were investigated and compared with the embedded structured CaPi modified PLGA nanoparticles (embedded-pDNA-CaPi-PLGA-NPs). The results showed that the obtained CS-pDNA-CaPi-PLGA-NPs were spherical in shape with an average particle size of (155 +/- 4.5) nm, zeta potentials of (-0.38 +/- 0.1) mV, entrapment efficiency of (80.56 +/- 2.5)% and loading efficiency of (1.16 +/- 0.04)%. The CS-pDNA-CaPi-PLGA-NPs were stable in the release media and could protect pDNA against nuclease degradation. And they also exhibited sustained release of pDNA in vitro. The highest gene transfection efficiency of the CS-pDNA-CaPi-PLGA-NPs in vitro reached (24.66 +/- 0.46)% (after 72 h transfection), which was significantly higher than that of free pDNA [(0.33 +/- 0.04)%, P < 0.01] and the pDNA-PLGA-NPs [(1.5 +/- 0.07)%, P < 0.01]. Besides, the transfection lasted for longer time than that of embedded-pDNA-CaPi-PLGA-NPs and the cytotoxicity of it was significantly lower than that of PEI (P < 0.01). These results indicate that CS-pDNA-CaPi-PLGA-NPs are a promising non-viral gene vector. Key words: gene delivery system; polylactic-co-glycolic acid; calcium phosphate; nanoparticle

BACKGROUNDThere has been a marked global increase in the incidence of human Campylobacter enteritis in recent years. This study investigated the epidemiological and clinical features of Campylobacter enteritis in adult patients suffering from acute diarrhea.

METHODSThis was a retrospective review of Campylobacter enteritis in adult patients with acute diarrhea presenting at Beijing University First Hospital, Beijing, China, in the summer and autumn (April to October) of 2005 to 2009. The data collected included the species of campylobacter identified, and the age, gender, clinical manifestations and results of laboratory test on stool samples collected from the patients. Campylobacter sensitivity tests to various antimicrobial agents were conducted on 80 specimens. Chi-square tests were applied using SPSS13.0 software and a two-sided P value of < 0.05 was considered statistically significant.

RESULTSCampylobacter spp. isolated from the stool specimens of 142 patients with diarrhea represented 14.9% of all the cases examined. C. jejuni was identified in 127 patients (89.4%) and C. coli in 15 others (10.6%). The infection incidence was highest in the age range of 21 - 30 years which comprised 21.7% of the total cases examined. Most cases of diarrhea (46 patients) occurred in June. Watery diarrhea (97.2%), abdominal pain (72.5%) and fever (64.8%) were the most common manifestations of enteric campylobacteriosis. Only four patients (2.8%) had bloody diarrhea. The antimicrobial resistance rates were: cefoperazone (100%), levofloxacin (61.3%), gentamicin (12.5%), erythromycin (6.3%), and azithromycin (2.5%).

CONCLUSIONSCampylobacter was prevalent among adults with acute diarrhea from 2005 to 2009 in Beijing, China. The large number of those afflicted by the disease warrants the commission of a large multicenter study to determine the extent of enteric campylobacteriosis in this region.
