Objective The aim of this study was to investigate the distribution and clinical significance of CD8+ T cells in bladder cancer tissues in situ.Methods Immunohistochemistry were used to examine the distribution of CD8+ T cells in bladder cancer tissues,which were obtained from January 2003 to December 2009 from 302 patients.Among all the patients,262 were male while 40 were female;mean age is 60 years;tumor size ≤ 3 cm was in 235 and tumor size ＞ 3 cm was in 67;Unifocal tumor was in 214 and multifocal tumors were in 88.Amount of tumor stage Ta-T1 was 212 and T2-T4 was 90.Sixteen patients have lymph node metastasis.Histological low grade was diagnosed in 175 and histological high grade was diagnosed in 127.According to the differences between anatomic structure and cellular composition,bladder tumor tissues can be classified to two localization patterns:(1) intratumoral regions,defined as tumor cell nests;(2) stromal regions,defined as stromal areas that lack direct contact with tumor cells.Therefore,we divided 302 bladder cancer patients into two groups based on the median frequency of intratumoral CD8+ T cells (median,3/× 400 high resolution) and stromal CD8+ T cells (median,37/× 400 high resolution),respectively.x2 analysis was used to evaluated the correlation between CD8+ T cell density and clinicalpathological variables.Kaplan-Meier analysis and Cox proportional hazards regression models were applied to estimate overall survival (OS).Results CD8+ T cells were predominantly located in the intratumoral regions (mean,14 ± 2/× 400 high resolution) rather than in associated stromal regions (mean,50 ± 3/× 400 high resolution,P ＜ 0.05).The density of intratumoral CD8+ T cells was inversely associated with age (P =0.026),tumor size (P ＜ 0.05) and tumor stage (P ＜ 0.05),and could represent a favorable prognostic predictor of OS (HR =0.427,P =0.003).However,the density of stromal CD8+ T cells was positively associated with age (P =0.004) and histological grade (P ＜ 0.01),and could represent an adverse prognostic predictor of OS (HR =2.206,P =0.009).Conclusions Our findings suggest that intratumoral/ stromal CD8+ T cells could potentially serve as favorable/ adverse prognostic markers for bladder cancer patients,respectively.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.

Objective To investigate the dynamic changes and the clinical significance of T-cell subsets and serum soluble interleukin-2 receptor (sIL-2R)in neonates with hyperbilirubinemia.Methods Thirty-one neonates with hyperbilirubinemia, admitted to the hospital from Decembr 1,2006 to January 31, 2007, were enrolled and divided into two subgroups: severe jaundice group and mild jaundice group according to the bilirubin level. Thirty-two age-mached healty newborns were as controls(control group Ⅰ). The T-cell subsets and sIL-2R of peripheral venous blood samples from these neonates were measured and compared. Sixteen of these 31 neonates with hyperbilirubinemiawere followed up and another twenty-six age-mached healty newborns were as controls(control group Ⅱ ). The level of serum bilirubin in convalescence of sixteen hyperbilirubinemia neonates and control group Ⅱ were tested and analyzed also. Results The levels of CD3, CD4, CD4/CD8 in the neonates with hyperbilirubinemia were lower compared with those of control group Ⅰ [(54.0±5.1)% vs (62.0±4.7)%, (26.8±5.0)% vs (43.0±4.7)%, 0.8±0.1 vs 1.4±0.2] (P＜0.01), but was higher in convalescence than in peak phase[ (62.4±3.3)% vs (55.1±4.2)%, (43.6±2.5)% vs (26.1±4.4)%, 1.4 ± 0.1 vs 0.8±0.1] (P＜0.01). The peak level of sIL-2R in the hyperbilirubinemia group was (319.4± 185.2) kU/L, higher than that in the convalescence [(129.7±99.3) kU/L] and in the control group Ⅱ [(171.9±102.2) kU/L] (P＜0.01). The serum bilirubin level showed negative correlation with CD4/CD8 ( r = -0.99, P ＜ 0.01 ) and positive correlation with sIL-2R (r=0.95, P＜0.05). The sIL-2R level was negatively correlated with CD4/CD8 (r=-0.92, P＜0.05). Conclusions Neonates, when suffering from hyperbilirubinemia, are immunosuppressed which may recover with the alleviation of jaundice.

Objective To investigate the effects of siRNA targeting decoy receptor 3 on the cell proliferation of ovarian carcinoma cell CAOV3. Methods We constructed siRNA targeting decoy receptor 3,which was transfected into ovarian carcinoma cells CAOV3 , and observed the effects of DcR3 siRNA on the cell proliferation of CAOV3 cell by MTT experiment. The experiment contained 3 groups, including the normal control group (CAOV3 cell was not transfected), the negative control group (CAOV3 cell was transfected with blank vector) and the experimental group (CAOV3 cell was transfected with DcR3 siRNA). The expression levels of DcR3 mRNA were detected by Real-time PCR. Results DcR3 siRNA recognized and degraded DcR3 mRNA in CAOV3 cells of the experimental group. DcR3 mRNA of the experimental group was significantly decreased. The proliferation of CAOV3 cell was significantly decreased by DcR3 siRNA comparing with the normal control group and negative control group (P < 0.01). Conclusion DcR3 siRNA can inhibit the proliferation of ovarian cancer cell line CAOV3 by recognized and degraded DcR3 mRNA.

Objective To investigate the effects of [Gly14]-Humanin(HNG) on SOD, MDA, GSH and cell apopto?sis in a rat model of secondary brain injury. Methods One hundred thirty-five adult and healthy male rats were random?ly divided into 3 groups: sham model group (n=45), vehicle control group (n=45) and HNG group (n=45). Secondary brain injury was induced in the vehicle control and HNG groups using improved Feeney method. Vehicle control received abdominal injections of Sodium Chloride Injection (2 ml/kg) whereas the HNG group received abdominal injections of HNG (2 μL/kg) immediately and 24 h after injury. Each group was divided into three subgroups (n=15 rats per each group) by sacrificed time including 1 h, 3 d, and 7 d after injury. The expression levels of SOD, MDA and GSH of the brain tissue were analyzed and the cell apoptosis was examined using TUNEL method after brain contusion. Results MDA and cell apoptosis around the lesion started to increased at 1h, reached a peak at 3d and then gradually subsided but still remained a higher level at 7 d than 1 h. HNG significantly attenuated brain injury-induced increase in MDA and apopto?sis at all time points (P<0.05). By contrast, SOD started to decrease at 1h, reached the lowest point at 3 d and then gradu? ally recovered but still remained a lower level at 7 d than 1 h. HNG significantly mitigated brain injury-induced increase in MDA and apoptosis at all time points (P<0.05). The time course of GSH expression followed a pattern similar to that of MDA. MDA expression was strongly positive correlated with the number of cell apoptosis (r=0.720, P<0.05), strongly neg?ative correlated with the level of SOD and GSH(r=-0.702, P<0.05;r=-0.674, P<0.05). Conclusions After brain injury, HNG inhibits oxidative stress levels and reduces apoptosis, thereby mitigating secondary brain injury.

Objective To evaluate the value of pre-operative 99Tcm-MIBI SPECT/CT in patients with HPT by comparing with planar 99Tcm-MIBI and ultrasound imaging. Methods A total of 57 patients (9 males, 48 females; average age: (52.9±15.5) years) were enrolled into this retrospective study. They all underwent 99Tcm-MIBI planar scintigraphy, 99Tcm-MIBI SPECT/CT and ultrasound during March to October in 2016. All patients received parathyroidectomy and the surgical pathology was considered as the gold standard. The diagnostic efficiencies were compared using χ2 test. Results A total of 86 HPT lesions were confirmed, including 47 lesions in 46 PHPT patients and 39 lesions in 11 SHPT patients. The sensitivities of SPECT/CT, planar, ultrasound and combined imaging (planar plus ultrasound) were 87.21%(75/86), 69.77%(60/86), 65.12%(56/86) and 84.88%(73/86), respectively. The overall sensitivity of SPECT/CT was significantly higher than that of individual planar imaging and that of ultrasound (χ2 values: 4.691 and 7.818, both P<0.05), but similar to that of the combined imaging (χ2=0.044, P>0.05). No significant difference was observed among the specificities of all these modalities (χ2=2.219, P>0.05). For PHPT lesions, the sensitivities of SPECT/CT, planar imaging, combined imaging and ultrasound were 9574%(45/47), 93.62%(44/47), 97.87%(46/47) and 76.60%(36/47), respectively. No statistically significant difference was found in the sensitivity of the former 3 modalities (χ2=1.044, P>0.05), but the sensitivity of ultrasound was the lowest(χ2=16.223, P<0.05). For SHPT, the sensitivities of the corresponding 4 modalities were 76.92%(30/39), 41.03%(16/39), 51.28%(20/39) and 69.23%(27/39), respectively. SPECT/CT was significantly superior to planar imaging and ultrasound(χ2 values: 10.386 and 5.571, both P<0.05), but comparable to the combined imaging(χ2=0.586, P>0.05). Only SPECT/CT could accurately localize 5 ectopic HPT lesions. Conclusion Compared to planar imaging and ultrasound, SPECT/CT has higher sensitivity for SHPT patients, and could provide precise localization for ectopic lesions, thus facilitating patient planning for minimally invasive surgery.

OBJECTIVETo understand the laws and characteristics of silicosis incidence of the workers exposed to the uranium dust from 1956 to 2002.

METHODSThe length of employment, age of occurrence of silicosis, and its duration and death age were compared between the uranium miners and uranium geological prospecting teams, and also between the miners exposed to uranium dust and those exposed to mixed uranium dust by single factor analysis method.

RESULTSWith time going on, the length of employment, age of occurrence of disease and its duration and death age were prolonged respectively in the workers exposed to uranium dust. The length of employment and age of occurrence of disease in uranium geological prospecting teams [(10.15 +/- 5.95) and (40.60 +/- 9.86) years respectively] were shorter than those in uranium miners [(14.23 +/- 8.12) and (41.38 +/- 10.98) years], but the duration (P(50)) and death age were longer [(14.29 years vs 12.52 years), (53.69 +/- 10.04) years vs (51.45 +/- 10.85) years respectively]. The length of employment and age of occurrence of disease in those exposed to uranium dust only [(11.78 +/- 8.06) and (38.04 +/- 9.89) years] were shorter than those exposed to mixed uranium dust [(12.74 +/- 6.29) years, (41.40 +/- 10.67) years], but the duration (P(50)) and death age were longer than the mixed uranium dust ones [(14.59 years vs 13.20 years), (53.93 +/- 10.60) years vs (51.82 +/- 10.20) years].

CONCLUSIONThe difference in the occurrence of silicosis in the workers exposed to uranium dust may be attributed to the physical and chemical character of the uranium dust and the different working circumstance.
