OBJECTIVE: To observe the chemical groups changing in rat kidney with regard to fatal hyperthermia by Fourier transform infrared microspectroscopy (FTIR-MSP) and to provide a new method to diagnose fatal hyperthermia. METHODS: Rats were sacrificed by hyperthermia, brainstem injury, massive hemorrhage and asphyxiation and divided into groups. The renal samples were dissected immediately after death. The data of infrared spectroscopy in glomerulus were measured by FTIR-MSP. RESULTS: The absorbances of 3290, 3070, 2850, 1540 and 1396 cm(-1) significantly increased (P < 0.05), and the ratios of Al650/A3290 and A1650/A1540 significantly decreased (P < 0.05) in group of hyperthermia. CONCLUSION FTIR-MSP can analyze the changes of chemical groups of kidney as an auxiliary diagnosis for discriminating hyperthermia with other causes of death.

Objective To develop a blood gas,acid-base imbalance analysis computer software to diagnose systematically,rapidly,accurately and automatically determine acid-base imbalance type,and evaluate the clinical application. Methods Using VBA programming language,a computer aided diagnostic software for the judgment of acid-base balance was developed. The clinical data of 220 patients admitted to the Second Affiliated Hospital of Guangzhou Medical University were retrospectively analyzed. The arterial blood gas〔pH value,HCO3-,arterial partial pressure of carbon dioxide(PaCO2)〕and electrolytes included data(Na+and Cl-)were collected. Data were entered into the software for acid-base imbalances judgment. At the same time the data generation was calculated manually by H-H compensation formula for determining the type of acid-base imbalance. The consistency of judgment results from software and manual calculation was evaluated,and the judgment time of two methods was compared. Results The clinical diagnosis of the types of acid-base imbalance for the 220 patients:65 cases were normal,90 cases with simple type,mixed type in 41 cases,and triplex type in 24 cases. The accuracy of the judgment results of the normal and triplex types from computer software compared with which were calculated manually was 100%,the accuracy of the simple type judgment was 98.9% and 78.0% for the mixed type,and the total accuracy was 95.5%. The Kappa value of judgment result from software and manual judgment was 0.935,P=0.000. It was demonstrated that the consistency was very good. The time for software to determine acid-base imbalances was significantly shorter than the manual judgment(seconds:18.14±3.80 vs. 43.79±23.86,t=7.466,P=0.000),so the method of software was much faster than the manual method. Conclusion Software judgment can replace manual judgment with the characteristics of rapid,accurate and convenient,can improve work efficiency and quality of clinical doctors and has great clinical application promotion value.

Purpose To explore the immunohistochemical features of neuroendocrine markers, CKpan and TTF-1 and their relationship to TNM stage and prognosis in small cell lung cancer (SCLC). Methods The expression of NSE, CgA, Syn, CD56, TTF-1 and CK-pan in SCLC tissue specimens were detected using immunohistochemical EnVision indirect method. Clinical data and TNM stage of 90 patients were collected and the overall survival ( OS) was followed up by telephone. Results Of 90 cases of SCLC, the vast majority were occured in the elderly men. The ratio of man to woman was 5 to 1. The median age was 64 years old. The stageⅠ+Ⅱ was 21 cases, 30 in stageⅢand 39 cases in stage IV. The positive rate of immunohistochemical staining of neuroendocrine markers for NSE, CgA, Syn and CD56 were 83. 3%, 70%, 65. 5% and 86%, respectively. The positive rate of CKpan, TTF-1 were 92. 2% and 81. 1%. Kaplan-Meier analysis indicated that the expression of TTF-1 and NSE were significantly correlated with the TNM stage and over-all survival of patients with SCLC (P<0. 05). The median OS was 8 months in positive expression of TTF-1, which was higher than those in negative expression of TTF1 (5. 5 months)(P=0. 000). The median OS was 7 months in NSE positive expression which was lower than those in negative expression of NSE (11 months)(P=0. 009). The median OS of stageⅠ+Ⅱ,ⅢandⅣwere 16 months, 9 months and 4 months with significant difference ( P=0. 000 ) . Cox multivariate analysis indicated the TTF-1 expression and TNM were independent prognostic factors for the OS of the SCLC patients. Conclusion Most of SCLC has neuroendocrine differentiation, expression CKpan and TTF-1. The expression of TTF-1 may be negative correlation but NSE positive correlation with the prognosis of SCLC patients. And the TTF-1 expression and TNM may be independent prognostic factors for the OS of the SCLC patients.
