The levels of ?_2-m、IgG and Alb in CSF of 13 patients with cerebral haemorrhage and 20 patients with cerebral thrombosis and the levels of ?_2-m in CSF of control group consisting of 14 eases were measured. It Was showed that the levels of ?_2-m in CSF of the two groups of the patients with cecrebrovascular disease were obviously higher than that of the control group and the levcls of ?_2-m in CSF of the two groups of the patients with cerebrovascular discase also had rclation to the levels of ?_2-m in serum of the groups of the patients themselves, the valucs of ?_2-m did not corre- lated with the valucs of IgG or Alb in CSF of the paticnts with cerebral hacmorrhage, but there existed a strong correlation between IgG and Alb in CSF of these patients. The values of ?_2-m, IgG and Alb in CSF of patients with cerebral thrombosis were exactly inversdy correlated with that of patients with cerebral haemorrhage. Reviewing some other data about ?_2-m the authors suggest that the clevated ?_2-m in CSf may indicate an increased cell-mediated immune phenomenon of central nervous system in teh pathological process of cerebral haemorrhage, but this phenomenon in the pathological process of cerebral thrombosis is not obviuos.

Objective To evaluate carbon nanoparticles suspension in protection and identification of parathyroid in total thyroidectomy for thyroid papillocarcinoma.Methods This retrospective analysis included the clinical and pathological data of 97 patients from January 2014 to December 2014,52 cases injected carbon nanoparticles suspension (the test group).Serum calcium and parathyroid hormone (PTH) were measured preoperatively and on lst,3rd,7th day and one month postoperatively.Results Incidental parathyroidectomy occurred in 1 case (1.9％,1/52) in test group and in 7 cases (15.6％,7/45) in control group(P ＜0.05).The mean numbers of parathyroid glands identified intraoperatively were 3.1 ± 0.4/case and 2.6 ± 0.3/case respectively (P ＜ 0.05).The occurrence of temporary PTH hypofunction was 19.2％ (10/52) and 42.2％ (19/45) respectively (P ＜ 0.05).Also,test group had a higher level of PTH on postoperative day 1,3,7 and one month (P ＜ 0.05).Conclusions Carbon nanoparticles suspension significantly improved the identification of parathyroid gland during thyroid cancer surgery and reduced the risk of incidental parathyroid ectomy in total thyroidectomy.

Purpose:It is the authors' intention to improve the diagnostic and differential diagnostic accuracy of ultrasound for acute tes-tis diseases by analyzing the sonographic features.Materials and Methods:The sonographic features of 78 acute testis diseasess were analyzed.The results were compared with the clinical,surgical and pathological results.Results:78 patients had obviously different sonographic features between different types of acute testis diseases.12 testicular tumors were big mass with uneven internal echoes and often with calcification.The distributions of the vessels in the lesions were irregular or branch-like.26 cases of testicular contusion had scrotal wall edema and thickening,with low echo and liquid collection in the lesions.21 cases of acute orchitis usually intumesced with color ball-shaped rich blood flow signals.18 cases with testicular torsion had blood flow on the affected side decreased or disappeared,lcase of tuberculocele showed extremely uneven and various echoes mixed in testis.Conclusion: A fast and exact diagnosis or differential diagnosis of acute testis diseases can be obtained with ultrasound.

OBJECTIVETo evaluate facial morphology characteristics of patients with unilateral complete cleft lip and palate (UCCLP) after cleft palate repair in different periods.

METHODS46 nonsyndromic UCCLP patients were chosen as test group and divided into three kinds (under 4-year-old, 4-7-year-old, over 7-year-old) according to periods of palate repair. 38 age and gender matched non-clefts children were involved as control group. 26 cephalometric measurements were measured to evaluate facial morphology of four groups.

RESULTSCompared with patients who received palate repair before 4-year-old, patients who received repair after 4-year-old had more protrusive ANS point (Ba-N-ANS, Ba-ANS) and less Y-axis angle. Patients who received palate repair after 7-yesr-old had greater A-PMP and ANS-PMP than patients who received palate repair before 4-year-old, patients who received palate repair before 7-year-old had smaller ANS-Me but after had no significant difference when compared with non-clefts.

CONCLUSIONWhenever palate repair is undertaken in the period of maxillary growth and development, patients' maxillary growth would be restrained, the delayed repair sample have better lower face height, maxillary protrusion, maxillary sagittal length and mandible growing direction when compared with the early repair sample, that is to say, the delayed repair sample have preferable head-face morphology.

Exposure to ionizing radiation intervenes in genomic stability and gene expression,resulting in the disruption of normal metabolic processes in cells and organs by causing complex biolog-ical responses.Altered genomic variations,gene expression and metabolite concentrations in blood or tissue samples reflect systemic radiation damage.With the application of new techniques and exten-sive study on the mechanisms for ionizing radiation damage,related indicators such as chromosomal variation,gene expression,lipid and metabolism are being recognized and promise to be the markers for early diagnosis and prognosis of radiation exposure.Therefore,this article reviews recent progress in and potential applications of biomarkers related to ionizing radiation injury.

Objective: By detecting the expression of interleukin-13 (IL-13) and periostin in the airway of asthmatic patients, the pathological changes and pulmonary functions of airway tissues in asthmatic patients were evaluated, and the role of IL-13 and periostin airway remodeling in bronchial asthma was preliminarily explored. Methods: The bronchial tissues adjacent to tumor nest were obtained from 12 patients with lung cancer complicated with bronchial asthma (asthmatic group) and 12 lung cancer patients without bronchial asthma (non-asthmatic group) after lung cancer resection. Pulmonary function was measured for all subjects before surgery. Pathological changes of airway tissues and degree of airway remodeling were assessed by hematoxylin-eosin (H&E) staining, masson′s trichrome staining, and periodic acid-silver methenamine (PASM) staining of paraffin-embedded sections. The expression of IL-13 and periostin in bronchial tissues were evaluated by immunohistochemistry. Results: Values of the forced expiratory volume in 1 second of the predicted value (FEV1% pred) and FEV1/forced vital capacity (FEV1/FVC%) in asthmatic patients were significantly decreased compared with the non-asthmatic patients (P<0.05), indicating that lung function was impaired in asthmatic patients. There was more severe airway remodeling representing as thickening of basement membranes, collagen deposition, and increasing of goblet cells and fibroblasts in asthmatic patients than in non-asthmatic patients (all P<0.05). The expression of IL-13 and periostin were higher in asthmatic tissues than in non-asthmatic tissues (P<0.05). The immunohistochemical expression of IL-13 and periostin in bronchial tissues were positively correlated with the degree of airway remodeling in asthmatic patients, and the expression of IL-13 and periostin in bronchial tissues were positively correlated with each other. Conclusions The expression of IL-13 and periostin were increased in bronchial tissue in patients with asthma. They work together to promote the occurrence of airway remodeling, which eventually lead to a decline in lung function.

ObjectiveTo investigate the association of lipid ratios with diabetes and pre-diabetes in residents aged 35-75 years in Changzhou City. MethodsA multistage whole-group random sampling method was used to survey permanent residents aged 35-75 years in Tianning and Wujin districts of Changzhou City， and the study data were obtained by questionnaires， physical examination and laboratory tests. The relationship between lipid ratios and diabetes and pre-diabetes was analyzed by dichotomous logistic regression method. ResultsThe prevalence of diabetes in the surveyed population in Changzhou was 18.69%， and the prevalence of pre-diabetes was 10.53%. In the total population， the risk of pre-diabetes was significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 68%， 93% and 38%， respectively； the risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. The risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. All three lipid ratios increased in women compared to men， leading to a stronger association with increased risk of diabetes and pre-diabetes. ConclusionLipid ratios TC/HDL-C， TG/HDL-C， and LDL-C/HDL-C were correlated with the risk of diabetes and pre-diabetes in people aged 35-75 years， with TG/HDL-C having the strongest association with diabetes and pre-diabetes， and is expected to be a key predictor for assessing the development of diabetes.

【Objective】 To investigate the variation of ferric metabolism indexes in male regular platetpheresis donors (MRPDs) with the low iron storage (plasma ferritin <30 μg/L). 【Methods】 The ferric metabolism indexes of 137 MRPDs with ferritin <30 μg/Lwere detected, including serum free iron (sFI), hemoglobin (Hb), unsaturated iron binding capacity (UIBC), total iron binding capacity (TIBC), transferrin (TRF) and prealbumin (PALB). The correlation between these indexes and the level of ferritin, the total number of platelet donation and the number of platelet donations in the previous year were analyzed. 【Results】 The UIBC of MRPDs with ferritin <30 μg/L showed a significant upward trendin comparison with the normal reference value, with the median level of UIBC at 55.1 μmol / L. The level of serum iron decreased significantly, with the median level at 10.9 μg / L. The level of ferritin was correlated with UIBC and Hb, and the indexes of iron metabolism were generally correlated to each other. The number of platelet donation in the previous year was correlated with TIBC, UIBC and TRF. The total number of platelet donation was correlated with TIBC and TRF. 【Conclusion】 MRPDs with ferritin <30 μg/L showed abnormalferric metabolism. It is necessary to detect both ferritin and ferric metabolism indexes to evaluate the iron deficiency in MRPDs.

【Objective】 To evaluate the residual risk of hepatitis C virus (HCV) in blood screening among voluntary blood donors in Zhengzhou. 【Methods】 The ELISA and NAT screening results of 497 171 voluntary blood donors in Zhengzhou from January 2019 to December 2020 were collected through the information management system of our blood center.The residual risk of HCV was assessed using the Prevalence-Window Period Residual Risk Model. 【Results】 The residual risk among repeated and first-time blood donors was 1∶132 280 (95% CI: 1∶95 520~1∶188 820) and 1∶44 090 (95% CI: 1∶31 840~1∶62 940), respectively. The overall residual risk of blood donors screening was 1∶68 540 (95% CI: 1∶65 910~1∶130 290). The reactive rate of HCV screening in first-time blood donors (0.144%, 334/231 168) was significantly higher than that in repeated blood donors (0.014%, 36/266 003) (P<0.05), and the reactive rate of repeated blood donors in 2019 (0.019%, 26/135 267) was significantly higher than that in repeat blood donors in 2020 (0.008%, 10/130 736) (P<0.05). 【Conclusion】 The residual risk of HCV among voluntary blood donors in Zhengzhou is low.The publicity and recruitment should be further strengthened to establish a stable team of voluntary blood donation, and health consultation and physical examination should also be strengthened to further reduce the residual risk of blood transfusion.
