Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

International Eye Science 2017;17(10):1960-1962
AIM: To assess the effect of two different suture methods on the degree of pain and corneal epithelium healing condition after pterygium excision combined with autologous conjunctival flap graft transplantation. ·METHODS: Retrospective case-series study. According to the suture method, a total of 92 patients (92 eyes) with pterygium who received treatment in the First Affiliated Hospital of Huzhou University from June 2015 to June 2016 were divided into two group. There were 48 patients ( 48 eyes) in Group A were received intermittent suture, and 44 patients ( 44 eyes ) in Group B were received continuous interlocking suture. The degree of pain after surgery were evaluated between the two groups at 2h, 1d and 1wk after surgery by visual analogue score ( VAS). The healing status of corneal epithelium were observed between the two groups at 1d and 1wk after surgery by fluorescent staining. ·RESULTS: There was no significant difference in the average pain value 2h after surgery between Group A and Group B (P>0. 05). The average pain values 1d and 1wk after surgery in Group B was lower than that in Group A respectively (P<0. 01). Mean scores of corneal epithelium healing condition at 1wk were significantly better in Group B than in Group A (0. 54 ± 0. 32 vs 0. 86 ± 0. 34, P<0. 05), while not significantly different at 1d after the surgery (4. 04±1. 46 vs 4. 30±1. 42, P>0. 05). · CONCLUSION: Compared to intermittent suture, continuous interlocking suture can release pain response after pterygium excision combined with autologous conjunctival flap graft transplantation and promote the healing status of corneal epithelium.

Objective To study the relationships of serum neuroglobin and neuron-specific enolase level with periventricular hemorrhage-intraventricular hemorrhage ( PVH-IVH) and periventricular leucumalacia ( PVL) in preterm infants. Methods There were 241 cases of preterm infants whose gestational age was less than 34 weeks and were admitted in NICU of Guangzhou Women and Children′s Medical Center, Guangzhou Huadu District Matermal and Child Health Hospital and Dongguan Taiping Hospital from Jan. 2010 to May. 2013, enrolled in the study. The serum level of neuroglobin and neuron-specific enolase were detected within 12 hours and on the 3 d, 7 d, 14 d after birth. Cranial ultrasound was preformed 2~3 d, 1week, 2weeks, 3weeks, and 4 weeks after birth. They also received Cranial MRI examination before discharge or when the correct gestational age reached 40 weeks. All 241 cases were divided into 3 groups ( no brain damage group, PVH-IVH group and PVL group) according to the result of cranial US and MRI. The differences of the serum levels of neuroglobin and neuron-specific enolase among each groups were compared. Results The results of cranial ultrasound and /or MRI showed: 162 cases had no brain damage ( in no brain damage group) , 50 cases had PVH-IVH ( in PVH-IVH group) , and 20 cases had PVL, 9 cases had PVL and PVH-IVH ( both in PVL group) . Within 12 h and 3 d after birth, the serum levels of neuroglobin in PVL group and PVH-IVH group was significantly higher than those in no brain damage group (P<0. 05), and the serum levels of neuroglobin in PVL group were signigicantly higher than those in PVH-IVH group ( P <0. 05 ) . On 7 d and 14 d after birth, the serum levels of neuroglobin were no significant difference between PVH-IVH group and no brain damage group ( P>0. 05 ) , and there were still significantly higher than those in no brain damage group and PVH-IVH group (all P<0. 05). The serum levels of neuron-specific enolase within 12 h and 3 d after birth in PVH-IVH group and PVL group were significantly higher than those in no brain damage group ( P<0. 05 ) , and there were no significant difference between PVL group and PVH-IVH group (P>0. 05). On 7 d and 14 d after birth, the serum levels of neuron-specific enolase in PVL group were no significant difference compared with PVH-IVH group and no brain damage group (all P>0. 05). Conclusion The increased serum levels of neuroglobin and neuron-specific enolase in preterm infants within 12 h and 3 d after birth would have certain clinical significance for judging whether early brain damage and PVL would happen.

Medical Journal of Chinese People's Liberation Army 1983;0(02):-
To obtain the criterion of Laser induced Autofluorescence (LIF) spectroscopy in the differentiation of normal lung tissue and lung cancer and study the feasibility of LIF spectroscopy in the diagnosis of lung cancer, the LIF spectra of normal lung and lung cancer in 42 surgical specimens have been measured with a detecting system which consists of an YAG laser(wavelength 355nm) and an optical multichannel analyzer(OMA). Spectroscopic differences between normal lung and cancerous tissues have been found which could be used as a criterion to distinguish from them . The pathological examinations were done to compare with the criterion. The results showed:① The location of the principal spectral peaks of the normal lung tissue (470.8?6.3)nm and lung cancer ( 463.7 ?4.8)nm are different( P
