BACKGROUND:Glutathione S-transferase can get rid of active oxygen and enhance organism's antioxidative capability.OBJECTIVE:To analyze the association between glutathione S-transferase P1-105 (GSTP1-105)genetic polymorphisms and human exercise capacity in the high altitude environment.DESIGN,TIME AND SETTING:A controlled analysis was performed in the PLA Institute of Physical Education in 2007.PARTICIPANTS:A total of 86 professional mountain climbers who had strong physical performance in the high altitude environment served as experimental subjects.An additional 90 healthy students randomly selected from the PLA Institute of Physical Education served as controls.METHODS:Blood sample was taken from 86 experimental subjects and 90 healthy controls for extraction of genome DNA.GSTP1-105 genetic polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism analysis.Distribution of GSTP1-105 alleles and genotypes were compared between experimental and control subjects.MAIN OUTCOME MEASURES:Distribution of GSTP1-105 genotype.RESULTS:Totally 3 GSTP1-105 genotypes were detected:homozygous genotype of the A allele (NA,also called wide type genotype),heterozygous genotype (NG),and homozygous genotype of the G allele (G/G).The frequency of the G allele and variant genotype (A/G+G/G)were significantly lower in the experimental than in the control subjects (P＜0.01).Variant genotype (A/G+G/G)was taken as an exposure factor,then OR=2.19 and 95% CI=1.16-4.13,indicating that in the high altitude environment,the exercise capacity in individuals with GSTP1-105 variant genotype was decreased by 1.19 times than that in individuals with GSTP1-105 wide type genotype.CONCLUSION:GSTP1-105 genetic polymorphisms correlate to human exercise capacity in the high altitude environment.Subjects with wide type genotype have exercise predominance.

Objective To investigate the impact factors for temperature of cornea(TOC) and analyse the relationship between TOC and evaporative dry eye. Methods Two hundred and fifty-seven patients(405 eyes) with normal lacrimal secretion received dry eye tests.Patients were divided into positive group and negative group according to the results,and were randomly subdivided into 4 groups with different environment temperature(T) and relative humidity(RH).For all eyes,TOC,body surface temperature(TBS) of forehead and center corneal thickness(CCT) were measured right after blinking.The impact factors for TOC and the differences in TOC between positive group and negative group were analysed.Results TOC was positively correlated with TBS(r=0.89),T(r=0.75) and RH(r=0.60)(P

Objective To investigate the clinical manifestations, endoscopic manifestations, histological characteristics, diagnosis and treatment of the primary gastrointestinal melanoma in China. Methods The gender, age, position, endoscopic manifestations, histological characteristics, treatment, prognosis of the primary gastrointestinal melanoma were gathered and analyzed by reviewing retrospectively the data of 2 cases seen at our hospital and 449 cases searched in CNKI from 1983 to 2015. Results The primary gastrointestinal melanoma was mostly seen in the rectum and anus, and secondly in the esophagus. A typical endoscopic finding was a protuberant or nodular tumor, with erosion or dirty surface on it. Most lesions were friable and easily hemorrhagic. The maximum diameters of most lesions, accounted for 83.3 %, were larger than 2.0 cm. The average value of the maximum diameters was (4.79 ± 2.67) cm. Most cases presented brown or black, followed by hoar. However, some lesions presented various colors, such as blue, red, even co-exited color or achromatic color. Preoperative misdiagnosed rate was 73.64 % and 1-year mortality was 54.19 %. Negative correlation was observed between survival time and lesion size, infiltration depth. Positive correlation was observed between lesion size and metastasis infiltration depth. Survival time had nothing to do with metastasis and age. Conclusion The primary gastrointestinal melanoma was highly aggressive, and usually found in the terminal age, usually together with extensive metastasis, misdiagnosed and poor prognosis. Knowing the clinical features, endoscopic manifestations, histological and immunohistochemical characteristics is the key to early diagnosis.

Objective To detect serum bone specific alkaline phosphatase(BAP) and osteocalcin(OC) in children with idiopathic short stature(ISS),and explore the status of osteoblast.Methods Thirty-six cases of ISS in this study were divided into two groups(preaddescence group and adolescence group),50 healthy children as control group.The height,weight and body mass index in every group were measured.Left hand and wrist were measured with CHN way for bone age.Serum BAP and OC were measured by enzyme linked immunosorbent assay(ELISA).Results BAP and OC in ISS group of preadolescence were(79.90?25.96) U/L,(60.96?18.46)?g/L,and(152.17?35.36)U/L,(76.16?28.03)?g/L in normal children.In the ISS group of adolescence BAP and OC were(108.33?35.20)U/L,(63.82?24.81)?g/L,and(156.30?35.29)U/L,(104.92?28.26)?g/L in normal group.There was significant difference between ISS and control group in both age in the levels of BAP and OC(Pa

? AlM: To examine choroidal thickness and its relationship with axial length and spherical equivalent by spectral domain optical coherence tomography ( SD -OCT ) in patients with myopic choroidal neovascularization ( mCNV) .
?METHODS: We prospectively recruited 30 cases of mCNV in Beijing Anzhen Hospital from October 2010 to December 2014. SD-OCT was used to measure choroidal thickness subfoveally and at 1. 5mm superiorly, inferiorly, nasally and temporally ( SFCT, SCT1. 5mm , lCT1. 5mm , NCT1. 5mm , TCT1. 5mm ) . Paired t- test was conducted to assess the difference of spherical equivalent, axial length and choroidal thickness between mCNV group and controls. Logistic regression analysis was performed to evaluate the correlation between spherical equivalent, axial length, choroidal thickness and mCNV.
?RESULTS: The difference of spherical equivalent and axial length between mCNV group and controls was not significant (P>0. 05). lnferior was decreased in mCNV group compared with controls (140. 85±33. 46μm vs 168. 95±45. 36μm). The difference was significant (P=0. 008). Logistic regression demonstrated that decreased choroidal thickness ( lCT1. 5mm ) at inferior location was associated with mCNV (OR=2. 12;95%CI 1. 35~3. 28;P=0. 02).
?CONCLUSlON: The decrease of lCT1. 5MM may be one of the risk factors of mCNV.

Objective To explore the accuracy of bedside arterial blood gas analyzer in detecting electrolytes and anionic gap (AG) in ICU patients, and compare it with auto-analyzer. Methods Results of blood sodium, potassium, chlorine, bicarbonate ions and AG measured by arterial blood gas analyzer and auto- analyzer of 376 ICU adult patients admitted to ICU were retrospectively analyzed. With the outcomes of auto-analyzer as standard, the correlation and difference of electrolytes and AG measured by 2 methods were analyzed. Results The sodium, potassium, chlorine and AG measured by auto-analyzer were 121 - 183 mmol/L, 2.13 - 6.77 mmol/L, 86 - 146 mmol/L and 1 - 62 mmol/L. The blood sodium, potassium, chlorine and AG measured by arterial blood gas analyzer were 114 - 180 mmol/L, 1.78 - 6.36 mmol/L, 94 - 150 mmol/L, -7 - 40 mmol/L. The blood sodium, potassium and AG measured by arterial blood gas analyzer were lower than those measured by auto-analyzer, but the blood chlorine was higher than that measured by auto- analyzer. There were statistical differences in the difference of low, normal and high electrolytes and AG between 2 methods (P<0.01). Conclusions The electrolytes and AG measured by arterial blood gas analyzer and auto-analyzer are significantly different, and the electrolytes measured by arterial blood gas analyzer are unreliable to calculate AG.

0.05).Conclusions The serum MMP-9 can be tested as an objective index in appraisal the severity of the left to right shunt.The increased level of MMP-9 may be one of important mechanism for developing heart failure process in children with left to right shunt CHD.Monitor the level of MMP-9 will help us find adverse myocardial remodeling earlier and begin treatment immediately to prevent heart failure developing.

AIM: To report a case of wet age-related macular degeneration (AMD) treat with multiple transpupillary themotherapy (TTT) and choroidal neovascularization (CNV) disappeared but retinal pigment epithelial(PRE) and choroidal atrophy occurred with a low vision at the end point.METHODS: Clinical data including fundus hotographs, fundus fluorescein angiography (FFA), indocyanine angiography (ICGA) and optical coherence tomography(OCT) was reviewed.RESULTS: A 72-year-old man complained about blurred vision of his left eye and FFA revealed polypoidal choroidal vasculopathy (PCV) in the macula. His left eye had stable vision of 0.1 for 6 years without any treatment of CNV. About 2 years later, his right eye presented a piece of CNV. During the period of 3 years, the lesion remained more (3×5 PD) and less (1×2PD) in size with remarkable exudates and bleeding, and 7 sessions of TTT were applied with 80-280mW, 2mm of spot, and 60 seconds exposure and with the interval of 3 months or more. The CNV lesion finally disappeared, but there left a white area in the macula and vision decreased from 0.3 to 0.04.CONCLUSION: Although CNV lesion can be eliminated by TTT, obvious atrophy of RPE cells and the choroids can happen and this may not be of help for patient vision. It suggests that the parameters of TTT will be lower than 120 mW/mm and limited less two sessions if applicable, especially for Asia people.
