Objective To investigate the expression level of Annexin Ⅱ in bronchial lung cancer tissue,alveolar lavage fluid(BALF) and pleural effusion and its value in the diagnosis of lung cancer.Methods From January 2014 to March 2016 in Jingzhou Infectious Disease Hospital,80 cases of patients with pleural effusion of lung cancer (Lung Cancer Group),40 patients with benign pleural effusion (benign group) were chose.The expression level of Annexin of two groups of patients with pleural effusion,BALF were detected and compared.Sixty specimens of department of pathology past (after lung cancer surgery cancer) and 30 cases of previously collected normal lung tissues (normal lung tissue) were collected,differential expression by immunohistochemical staining were compared between the two groups of Annexin Ⅱ protein.Results The positive expression of Annexin Ⅱ in lung cancer was 61.67％ (37/60),higher than that in normal lung tissue of 23.33％ (7/30),the difference was statistically significant(P＜0.001).The positive expression of Annexin Ⅱ in lung cancer patients was significantly correlated with rate of lymph node metastasis and clinical stage of lung cancer(P =0.039,0.029).Group of patients with pleural effusion,BALF expression of Annexin Ⅱ the level was higher than that in benign group(P＜0.001).When the critical value of Annexin in pleural effusion of lung cancer diagnosis was 10.94 μg/L,the sensitivity of diagnosis of lung cancer was 83.47％,the specificity was 80.66％,AUC value was 0.837.The critical value when BALF Annexin Ⅱ in the diagnosis of lung cancer was 52.08 μg/L,the sensitivity of diagnosis of lung cancer was 86.19％,the specificity was 89.22％,the AUC value was 0.898.Conclusion The expression level of Annexin Ⅱ in the BALF and pleural effusion of patients with bronchial lung cancer and lung cancer is increased,and it has a certain clinical value for the differential diagnosis of lung cancer.

Objective To investigate the diagnosis and treatment of the patients with lung cancer hospital-ized in affiliated hospital of Hainan Medical College.Methods A retrospective study was performed from January 1st 2005 to December 31th 2009 in the Hospital.201 patients were enrolled in this study.Results The average onset age of patients with lung cancer was 66 years old.No difference in different gender.The incidence of male was 72.1%, which was higher than of female(27.9%).Male to female ratio was 2.6:1.70.3% of male patients with lung cancer had a history of smoking.146 cases(72.6%)were diagnosed by clinical data,only 55 cases(27.4%)were diagnosed by histopathology.134 cases(66.7%)hadn′t indications for surgery.only 17 cases(25.4%)agreed to have surgery among 67 cases (33.3%)with indications for surgery,50 cases(74.6%)didn't agree to have surgery.34 cases (16.9%)had no indications for chemotherapy.40 cases(24.0%)agreed to have chemotherapy among 167 cases (83.1%)with indications for chemotherapy,but only 14 cases(35.0%)had completed 4 to 6 cycles of chemotherapy, and 26 cases(65.0%)hadn't completed 4 to 6 cycles.8 cases(4.0%)agreed to have radiotherapy.3 cases(1.5%) agreed to have targeted therapy.3 cases (1.5%)transfered to other hospital.Conclusion The ratio of lung cancer patients in male is higher than female in the hospital.smoking is closely related to male patients.Clinical diagnosis rate of patients is high,whereas histopathologic diagnosis rate is low.The rate of the intervention that patients accepted is low and many patients give up available management after the diagnosis is made.

BACKGROUND:Different races, genders, heredity, geographical environment can cause different bone ages. Therefore, an assessment of hand-wrist bone age has been done in the Han and Uygur adolescents and children in Xinjiang region.
OBJECTIVE: To investigate the actual conditions of hand-wrist bone age in Han and Uygur adolescents and children in Urumqi.
METHODS: 760 children and adolescents (aged 4.0-4.0 years) of Uighur and Han nationalities were enroled in this study. Two years acted as an age group. The hand-wrist bone age was estimated by hand-wrist X-ray using theChinese Wrist Skeletal Development Standard CHN Method. The correlation between bone age and chronological age was analyzed statisticaly as wel as difference in the bone age and chronological age between two ethnic groups.
RESULTS AND CONCLUSION: (1) A close correlation was found between hand-wrist bone age and chronological age for two ethnic groups (P < 0.05). (2) Thirteen age group showed higher bone ages than chronological ages, including four age groups of Han nationality girls aged 4.0-11.9 years, three age groups of Han nationality boys aged 4.0-9.9 years, three age groups of Uygur girls aged 4.0-9.9 years, and three age groups of Uygur boys aged 4.0-9.9 years. (3) The bone and chronological ages were higher in the Han girls aged 10-11.9 year than the Uygur girls aged 10-11.9 years as wel as in the Han boys aged 12-13.9 years than the Uygur boys aged 12-13.9 years. Results show that the two ethnic groups of children and adolescents exhibit the early mature trend of skeletal development in multiple age groups; and there is a difference in skeletal and chronological age between Han and Uygur adolescents in some age groups.

Objective To explore the clinical features, imaging and their diagnosis vaule of Baló's concentric sclerosis (BCS). Methods The clinical manifestation, laboratory examination, neuroimaging characteristics, pathology and follow-up of 12 (2 outpatients and 10 inpatients) cases of BCS were analyzed retrospectively. Results The onset age of 12 patients (male 4, female 8) ranged from 8 to 54 years old (mean 36.8 years). Unconcerned and slowness response were common in the disease onset (7 cases).Other symptoms and signs such as hypophrenia ( 10 cases), limitation of limb or hand movement (8 cases),urinary and fecal incontinence (7 cases), hypo-myodynamia (7 cases), positive pyramidal sign (6 cases)were not rare in course of disease. Eight cases underwent the examination of cerebrospinal fluid myelin basic protein, which increased in 7 cases. Demyelinating change and perivascular inflammatory infiltration were shown in 6 brain biopsies. The involvements of multi-lesions were found in 11 cases. Four patients underwent CT scanning and all the cases showed with hypodense lesions and couldn' t be enhanced. On MRI, all cases appeared round or round-like in shape. Enhanced lesions showed ring-like or half-ting-like shape (8 cases) and concentric ring (3 cases). It's easy to be misdiagnosed as brain tumor (8 cases).Conclusions BCS is a kind of demyelinating disease of subacute or chronic onset accompanied with cognitive disorder being the most common initiating symptoms. It's prone to be misdiagnosed. Diagnosis depends on MRI and corticosteroid treatment is effective. BCS has a good prognosis and presents with benign clinical course.

Objective To explore the clinical significance of serum concentrations of Cystatin C (CysC) in children with kidney disease in different disease courses. Methods The serum concentrations of CysC, creatinine(Cr) and endogenous creatinine clearance rate(Ccr) were determined in 182 children with kidney disease. They were divided into five study groups:normal renal function group (73 cases), compensatory renal disfunction group (44 cases), non-compensatory renal disfunction group (35 cases), renal failure group(22 cases) and end stage of renal failure group(8 cases). Meanwhile 70 healthy children were involved in control group. Relationships among CysC, Cr and Ccr were calculated and the diagnostic efficiency was assessed by comparing the areas under the ROC curves. Results The serum concentrations of CysC increased in different courses of renal function impairment in children and were significantly related to the severity of impairment. CysC was positively correlated to Cr and negatively correlated to Ccr. The areas under the ROC curves of Cr and CysC were 0.764 and 0.725. Conclusions The serum concentrations of CysC can accurately identify different impairment grades of renal function and the function of glomerular filtration. As an indicator of early reduction of renal function, its sensitivities and specificities are superior to Cr and Ccr. CysC can be a sensitive endogenous marker for glomerular filtration rate determination. With simple, convenient and applicable assays methods, CysC is essential for early diagnosis of children kidney diseases.

A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.
