Objective To investigate the respiratory burst function of neutrophils in very low birth weight infants (VLBWI).Methods Twenty two VLBWI was divided into two groups:neonatal respiratory distress syndrome (NRDS) and non NRDS (11 in each).The respiratory burst function of neutrophils in the peripheral blood of VLBWI within 48 hours after birth was determined using the flow cytometrydihydrorhodamine 1,2,3 method before and after the chemical stimulation of phorbol-12-myrismte 14 acetate (PMA),and the gp91Phox was also measured in resting neutrophils by flow cytometry.Twenty healthy term neonates served as controls.Mann-Whitney U test was used for statistical analysis.Results Before the stimulation of PMA,the percentage of activated neutrophils of VLBWI [(49.10±20.19) ％] producing a respiratory burst was higher than that of term neonates [(18.73 ±6.81) ％] (Z--4.911,P=0.000),however,after the stimulation of PMA,the percentage of activated neutrophils of VLBWI [(96.58 ± 3.44) ％] was lower than that of term neonates [(99.20±0.62) ％] (Z--3.186,P=0.001),and the stimulation index (SI) of VLBWI (171.40 ± 103.35) was lower than that of term neonates (306.30 ± 138.47),with significant difference (Z=-3.413,P=0.001).The geometric mean of gp91Phox in VLBWI (21.66± 19.87) was higher compared with term neonates (19.60±8.03),however,the difference was not significant (P=0.350).The percentage of neutrophils that expressed gp91Phox [(56.11 ± 29.40) ％] was lower in VLBWI than that in term neonates [(80.14± 14.87) ％],with significant difference (Z=-2.374,P=0.018).Before the stimulation of PMA,the percentage of activated neutrophils of VLBWI with NRDS (63.40± 16.45) ％] was higher than that of VLBWI without NRDS [(34.80± 11.65) ％],with significant difference (Z=-3.382,P=0.001),the SI of VLBWI with NRDS (129.46 ± 75.36) was significantly lower than that of VLBWI without NRDS (213.35 ± 113.49) (Z=-2.331,P=0.020).Conclusions Neutrophils producing a respiratory burst in both VLBWI and term neonates are active without stimulation of PMA,while the phenomenon is more obvious in VLBWI.Neutrophils in VLBWI and term infants can be activated by the stimulation of PMA,and express gp91Phox.The activation and gp91Phox expression of neutrophils in VLBWI with NRDS tend to be lower than those in VLBWI without NRDS.

Objective To explore the relationship between plasma homocysteine levels and diabetic retinopathy (DR).MethodIn 40 DR patients and 63 non-DR patients,the indexes including plasma homocysteine concentrations,duration of diabetes,ages,blood pressure,preprandial blood glucose(PBG),plasma GHbA,e,plasma lipids,serum folie acid and semm vitamin B12 were analyzed.ResultsPlasma homocysteine level was significantly higher in DR patients (12.9μmol/L) than that in non-DR patients (7.8μ.mol/L) (P＜0.01),and the relationship remained significant correlation after adjusted for duration of diabetes,GHbA1c,ages,serum folic acid and serum vitamin B12(OR = 1.23,P＜0.05).ConclusionHyperhomocysteinimia is a risk factor and an independent predieator of DR.

We investigated the roles of the crude antigen(CA) of Clonorchis sinensis and excretory secretory products (ESPs) in the polarization of Th1 and Th2 cells.Bone marrow-derived cells were generated from BALB/c mice and isolated into immature DCs;immature DCs were then treated with either CA (CA stimulated group),ESPs (ESPs stimulated group),LPS (positive control group) or PBS (negative control group) for 24 hours.Then the CD4+T cells were isolated from mouse spleen by using anti mouse-CD4 Microbeads,and further cocultured with stimulated DCs for another 72 hours.The purities of DCs and CD4+ T cells were evaluated by flow cytometry and the expressing levels of T-bet mRNA and GATA-3 mRNA were detected by real-time PCR.ELISA was used to detect the levels of IFN-γ and IL-4 cytokines in the supernatant.mRNA levels of T-bet and GATA-3 in the ESPs group were higher than those in PBS-stimulated group (P＜0.05).The concentrations of IFN-γ and IL-4 cytokines in the culture were increased in the ESPs group,compared with PBS stimulated group(P＜0.05).IFN-γ but not IL-4 was increased in CA group (P＜0.05).The results implied that CA might play a role in Th1 type immune response,and ESPs likely play roles in both Th1 and Th2 immune responses.

Objective To explore the risk factors for lung cancer-related cerebral infarction . Methods The hospitalized active lung cancer patients on anti-cancer therapy with no traditional stroke risk factors, who experienced an acute cerebral infarct in the First Affiliated Hospital of Guangxi Medical University from January 2005 to December 2015, were consecutively collected as the LCRS ( lung cancer-related stroke) group.The active lung cancer patients without cerebral infarction hospitalized at the same peroid matched with the LCRS group for age and gender were collected as the LC ( lung cancer ) group. Clinical data from the two groups were analyzed .Results A total of 139 LCRS patients and 139 LC patients were enrolled in the study , with 110 male and 29 female in each group , and there were no significant difference for the mean age between the LCRS group (52.1 ±10.4 years old ) and the LC group (52.1 ± 10.1 years old).Two or more acute ischemic lesions of the brain were showed by MRI in most patients in the LCRS group (117 cases, 84.2%).Compared with the LC group, more patients in the LCRS group were found with adenocarcinoma , metastasis, elevated plasma D-dimer, CA125 and CA199 levels [ 88 cases (63.3%) vs 47 cases (33.8%);98 cases (70.5%) vs 56 cases (40.3%);(468.38 ±291.37) μg/L vs (277.59 ±191.22) μg/L;(221.42 ±146.34) U/ml vs (106.84 ±69.97) U/ml;(254.68 ±185.84) U/ml vs (97.15 ±63.64) U/ml;with all P<0.001].By logistic regression analysis of multiple factors , the elevated plasma D-dimer, CA125 and CA199 levels were showed to be independent risk factors for the cerebral infarction (OR=1.003, 95%CI 1.001 -1.004; OR=1.006, 95%CI 1.003 -1.010; OR=1.011, 95%CI 1.007-1.015).Conclusions The elevated plasma D-dimer, CA125 and CA199 levels are the risk factors for the lung cancer related cerebral infarction , which may lead to hypercoagulation and induce cerebral infarction eventually .

Objective To investigate the correlation between serum level of gamma-glutamyl transferase (GGT) and coronary heart disease (CHD) in military pilots. Methods Sixty male military pilots hospitalized in Airforce General Hospital having coronary angiography examination(CAG) from March 2005 to May 2015 were involved then were divided into CHD group (n = 24) and control group (n = 36) according to the results of coronary angiography (CAG). The patients with CHD were divided into low score group (Gensini score ≤ 20) and high score group (Gensini score > 20) according to Gensini score. Results There were significant increase of the level of TG, GGT and decrease of the level of HDL-C in CHD group than those in control group(P<0.05);there was no significant difference with the level of GTT between high score group and low score group (P > 0.05); logistic regression analysis showed that serum GGT was an independent risk factor of CHD in military pilots (OR = 1.168, P < 0.01). Conclusion Serum GGT is associated with CHD in military pilots and is the independent risk factor of CHD in the pilots.

ObjectiveTo investigate the therapeutic effectiveness of low-power laser on myofascial pain syndrome. Methods73 self-controlled patients with myofascial pain syndrome were irradiated on myofascial trigger points with Nd:YAG laser in wavelength 830nm, power 500mW, 20 minutes per day for 5 times. At pre-and post-treatment,pain intensity and pressure pain of myofascial trigger points were checked. ResultsAfter treatment, score of pain intensity was reduced signficantly from (7.24±2.41) to (2.21±1.22) (P<0.001). The pressure pain of myofascial trigger points were improved . Conclusions Low-power laser can reduce the pain intensity and increase the pressure pain threshold of myoficial trigger points.

Abstract?AIM: To assess the current situation of trachoma in Shaanxi Province and analyze its epidemiology and clinical features.?METHODS: The World Health Organization ( WHO ) simplified trachoma grading system was used for the recognition and registration of cases of trachoma. Trachoma rapid assessment ( TRA ) was conducted and 30.3687 million people from Shaanxi province were screened. Eyelids, eyelashes, conjunctiva and cornea were examined.The prevalence of trachoma trichiasis ( TT) in Shaanxi Province was estimated.?RESULTS: Totally 987 cases with TT were collected in Shaanxi province, in which 395 cases were male and 592 cases were female. The overall TT prevalence was 0.0325‰.The age of TT cases ranged from 25-86 years old, and concentrated in the 60-80 years old, only 58 cases were <50 years old.There were 12 cases of TT combined corneal opacity (CO) and the ratio was 1.2%. Sixty-four patients were cured by electrolysis trichiasis, the remaining 923 patients corrected by surgery interventions.?CONCLUSION: Based on the results of this study, trachoma blind is no longer estimated as a public health problem in Shaanxi province, as the detection rate of TT was less than 1‰ which is the goal of “elimination of trachoma” worldwide.

OBJECTIVETo investigate the hemodynamics evidence of the descending branch of lateral circumflex femoral artery in a reversed way. To explore the clinical result of using the reversed descending branch of the lateral circumflex femoral artery as the receipt artery for free flaps for reconstruction of the leg soft-tissue defect.

METHODSFrom October 2005 to February 2012, 38 patients with severe leg soft-tissue defects were treated. The proximal antegrade and retrograde mean artery pressure of the descending branch of the lateral circumflex femoral artery in 16 of 38 patients were recorded during operation. All wounds had osteomyelitis, bone and tendon exposure requiring coverage reconstruction. And there was no recipient artery in the injured lower leg for free flaps in all 38 patients. Reversed descending branches of lateral femoral circumflex arteries were used as recipient arteries for free flaps (free latissimus dorsi flap, free thoracoumbilical flap, and free anterolateral thigh flap) in all patients. The flap donor site was closed directly or with the skin graft.

RESULTSThe proximal antegrade mean artery pressure of the descending branch of lateral circumflex femoral artery was(81.6 +/- 12.4) mmHg. The proximal retrograde pressure was(48.2 +/- 10.7) mmHg. The proximal retrograde mean artery pressure was 59.07 percent of the proximal antegrade pressure. The donor skin graft survived and wound healed primarily. After operation, 2 flaps had distal partial necrosis and healing was achieved after dressing change. All the other flaps survived completely without vascular problems. All the patients were followed up for 11 months to 2.5 years (mean, 1.6 years). The flap appearance was satisfactory. The texture and color of flaps in all cases were good.

CONCLUSIONSThe reverse descending branch of lateral circumflex femoral artery is a reliable recipient artery for the free flaps. It is an easy and simple technique that can be used for reconstruction of the defects in the lower leg, with the reversed descending branch of lateral circumflex femoral artery as recipient artery.
