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 clinical significance of dynamic determination of serum procalcitonin(PCT)levels in judgment of infection and prognosis in patients with severe craniocerebral injury.Methods A total of 80 patients with severe craniocerebral injury were selected and they were divided into infection group and non-infection group.Infection group was divided into improved group and non-improved group.Acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and Glasgow coma scale(GCS)score was compared between infection group and non-infection group.The level of serum PCT,white blood cell count(WBC),C-reactive protein(CRP)and interleukin(IL)-6 was compared on the first,third,fifth day of admission in intensive care unit among these groups.Results Infection group in 48 patients,and non-infection group in 32 patients.There was no significant difference in age,sex and GCS score between two groups(P ＞0.05).APACHE Ⅱ score in infection group was higher than that in non-infection group [(21.71 ± 7.13)scores vs.(15.32 ± 6.17)scores],and there was significant difference (P＜ 0.05).The level of serum PCT on the first day of admission in intensive care unit in infection group was higher than that in non-infection group[(2.15 ± 1.79)ng/L vs.(0.56 ± 0.47)ng/L],and there was significant difference(P＜ 0.05).There was no significant difference in WBC,CRP and IL-6 between two groups(P＞0.05).The level of serum PCT,WBC,CRP,IL-6 on the third day of admission in intensive care unit in infection group was higher than that in non-infection group,and there was significant difference(P＜ 0.05).The level of serum PCT on the fifth day of admission in intensive care unit in infection group was higher than that in non-infection group [(3.09 ± 1.98)ng/L vs.(1.06 ± 0.63)ng/L],and there was significant difference (P＜0.05).WBC,CRP,IL-6 on the fifth day of admission in intensive care unit was(15.13 ±6.32)×109/L,(103.56 ±40.62)mg/L,(230.41 ± 121.83)ng/L in improved group(38 cases),and (18.62 ±8.89)× 109/L,(134.38 ± 34.16)mg/L,(268.73 ± 138.12)ng/L in non-improved group(10 cases),and there were significant differences between two groups(P ＜ 0.05).The level of serum PCT on the first,third,fifth day of admission in intensive care unit in improved group was lower than that in non-improved group,and there was significant difference(P ＜ 0.05).Conclusion The alteration of serum PCT level may be used as one of the effective predictors for infection in patients with severe craniocerebral injury and for their prognosis.

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.
