Objective To investigate the effect of cyclosporine blood level at first year after kidney transplantation on patients with a survival time over 10 years. Methods 380 patients with functional allograft, a survival time over 10 years and long-term administration of cyclosporine A (CsA) were studied, and received CsA-based treatments. According to the blood CsA level at the first year after kidney transplantation, patients were divided into five groups: group 1, blood CsA level was above 0. 208 μmol/L (1 μmol/L = 1201.9 μg/L), group 2, blood CsA level between 0. 166-0. 208μmol/L; group 3, blood CsA blood level between 0. 125-0. 166 μmol/L; group 4, blood CsA blood level between 0. 083-0. 125 μmol/L; group 5, blood CsA level less than 0. 083 μmol/L. Systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine(SCr), uric acid (UA), cholesterol (CH), triglyceride (TG), alanine aminotransferase (ALT), direct bilirubin (DBil) and total bilibubin (TBil), albumin (Alb), hemoglobin (Hb), count of white blood cells and positive rate of proteinuria in 5 groups at the 1st, 5th and 10th year after kidney transplantation were analyzed. Results At the 5th year SBP in groups 1 and 2 was higher than in groups 3, 4 and 5. UA level in group 5 was lower than other groups, and Alb level in group 5 was higher than other 4 groups. Proteinuria positive rate in groups 4 and group was lower than other groups. At the 10th year after kidney transplantation,indexes among 5 groups had no statistically significant difference, except for SBP, DBP, DBil and CH in some groups. There was also no significant difference in SCr level among 5 groups at the 5th or 10th year after transplantation. Conclusion Blood CsA levels at the first year after kidney transplantation has no significant effect on long-term allograft function. But higher level of CsA (＞0. 166μmol/L) at the first year maybe predict high rate of hypertension, high blood UA and proteinuria at the 5th and 10th year after transplantation.

OBJECTIVETo investigate a method for quantitative differential diagnosis of damp-heat and cold-damp impeding syndrome of rheumatoid arthritis (RA) in Chinese medicine (CM).

METHODSLaboratory parameters were collected from 306 patients with RA. The clinical symptoms and laboratory parameters were compared between patients with these two syndromes (158 with RA of damp-heat impeding syndrome, and 148 with RA of cold-damp impeding syndrome), and a regression equation was established to facilitate discrimination of the two RA syndromes.

RESULTSThere were significant differences in disease activity score in 28 joints [DAS28 (4)], erythrocyte sedimentation rate (ESR), white blood cell count (WBC), C-reactive protein (CRP), platelet count (PLT), albumin (ALB) and globulin (GLB) between the two syndrome of RA (P<0.05). Logistic regression analysis showed that the parameters ESR, WBC, CRP, joint pyrexia, joint cold, thirst, sweating, aversion to wind and cold, and cold extremities were statistically useful to discriminate damp-heat from cold-damp impeding syndrome. The regression equation was as follows: P=1/{1+exp[-(3.0-0.021X (1)-0.196X (2)-0.163X (3)-1.559X (4)+1.504X (5)-0.927X (6)-1.039X (7)+1.070X (8)+1.330X (9))]}. The independent variables X (1)-X (9) were ESR, WBC, CRP, hot joint, cold joint, thirst, sweating, aversion to wind and cold, and cold limbs. A P value > 0.5 signified cold-damp impeding syndrome, and a P value < 0.5 signified damp-heat impeding syndrome. The accuracy was 90.2%.

CONCLUSIONThe regression equation may be useful for discriminating damp-heat from cold-damp impeding syndrome of RA.

BACKGROUNDType 2 diabetes mellitus (T2DM) has traditionally been considered to affect mainly the elderly; however, the age at diagnosis has gradually reduced in recent years. Although the incidence of young-onset T2DM is increasing, it is still not fully clear the onset characteristics and risk factors of early-onset T2DM. The aim of this study was to describe the initiating characteristics of early-onset T2DM in Chinese patients and evaluate the risk factors for diabetes mellitus.

METHODSThis cross-sectional controlled study was performed using a questionnaire survey method in outpatients of multiple centers in China. A total of 1545 patients with T2DM with an age at onset of <40 years were included, and the control group consisted of subjects aged <40 years with normal blood glucose level.

RESULTSIn patients with young-onset T2DM, the mean age and initial hemoglobin 1Ac at diagnosis were 32.96 ± 5.40 years and 9.59 ± 2.71%, respectively. Most of the patients were obese, followed irregular diet pattern and sedentary lifestyle, had life or work pressure, and had a family history of diabetes mellitus. Compared with subjects with normal blood glucose level, logistic regression analysis showed that waist-to-hip ratio (odds ratio [OR] 446.99, 95% confidence interval [CI] 42.37-4714.87), family history of diabetes mellitus (OR 23.46, CI 14.47-38.03), dyslipidemia (OR 2.65, CI 1.54-4.56), diastolic blood pressure (OR 1.02, CI 1.00-1.04), and body mass index (OR 0.95, CI 0.92-0.99) are independent factors for early-onset T2DM.

CONCLUSIONSWe observed that abdominal obesity, family history of diabetes mellitus, and medical history of hypertension and dyslipidemia are independent risk factors for early-onset T2DM. It is, therefore, necessary to apply early lifestyle intervention in young people with risk of diabetes mellitus.

Laser induced breakdown spectroscopy ( LIBS ) was proposed to rapidly discriminate microbe species. Ten species of microbes were prepared in lab. Filter papers were selected as substrate for enriching bacteria and enhancing the quality of LIBS. The images of plasma were collected by ICCD camera and LIBS spectra were obtained by spectrometers. The results displayed that the images and spectra were different from 10 bacteria. It was demonstrated that this method was feasible to discriminate bacteria species by analyzing image and/or spectroscopy. Furthermore, nine smooth and multiple scattering correction ( MSC) were utilized to preprocess the LIBS full-spectrum data in the wavelength range of 200-420 nm and 560-680 nm. And principal component analysis ( PCA) and PCA-RF ( Random forest) were compared to validate the accuracy of discrimination. The investigation showed that the PCA-RF model coupled with suitable methods in preprocessing data could identify bacteria. The accuracy was 99. 6% for ten species of microbes by evaluating LIBS spectra in training set, and 96. 7% in predicting set. This report indicated that it is feasible to differentiate bacteria species by analyzing LIBS spectra.

OBJECTIVETo explore the pattern of lymph node metastasis and evaluate the modes and extent of mediastinal lymph node dissection in patients with ≤ 3 cm, clinical stage I primary non-small cell lung cancer (NSCLC).

METHODSData of 270 eligible patients who underwent pulmonary resection with systematic lymph node dissection in our hospital between March 2012 and August 2013 were retrospectively analyzed in order to investigate the relationship between the clinicopathological features and lymph node metastatic patterns. Patients with multiple primary carcinomas or non-primary pulmonary malignancies and those who received any chemotherapy or radiotherapy or did not undergo systematic nodal dissection were excluded. The criteria of systematic nodal dissection included the removal of at least six lymph nodes from at least three mediastinal stations, one of which must be subcarinal. The data were analyzed and compared using Chi-square test.

RESULTSThe postoperative morbidity rate was 14.8% and no death occurred in this series. The imaging findings showed 34 cases of pure ground glass opacity lesions, 47 partial solid nodules, and 189 solid nodules. Apart from 34 p-GGO lesions, among the other 236 cases, ≤ 1 cm lesions were in 22 cases, 1 cm- ≤ 2 cm lesions in 138 cases, and >2 cm- ≤ 3 cm lesions in 76 cases based on radiologic findings. The pathological types included adenocarcinoma (n = 245), squamous cell carcinoma (n = 18) and other rare types (n = 7). The overall lymph node metastasis rate was 18.9% (51/270), and the incidence of lymph node involvement was 0(0/34) in cancers with p-GGO, 2.1% (1/47) in mixed solid nodules, 26.5% (50/189) in solid nodules, 18.2% (4/22) in nodules ≤ 1 cm, 14.5% (20/138) in 1 cm < nodules ≤ 2 cm, and 35.5% (27/76) in 2 cm < nodules ≤ 3 cm. The metastasis rates of non-specific tumor-draining region lymph nodes detected in the patients with positive and negative lobe-specific lymph node involvement were 20.0%-50.0% vs. 0-2.9% (P < 0.001).

CONCLUSIONSUsually NSCLC with p-GGO nodules has no lymph node metastasis, therefore, systematic nodal dissection may be not necessary. The larger the tumor size is, the higher the lymph node metastatic rate is for mixed or solid nodules. Intraoperative frozen-section examination of the lobe-specific lymph nodes should be performed routinely in patients with ≤ 2 cm stage I NSCLC, and systematic nodal dissection should be done if positive, but it may be not necessary if negative. However, the effectiveness of the systematic selective lymph node dissection still needs to be further confirmed.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.
