Objective To observe and compare the curative effects of zoledronic acid (ZA) combined with radiotherapy and ZA combined with chemotherapy in the treatment of bone metastasis of non-small cell lung cancer (NSCLC). Methods Seventy-eight patients with NSCLC bone metastasis treated by radiotherapy or chemotherapy were taken in our hospital from January 2010 to June 2014, including 39 cases of ZA combined conventional fractionation radiotherapy (radiotherapy combined group), and 39 cases of ZA combined with chemotherapy (paclitaxel liposome + cisplatin) (chemotherapy combined group). Each group had 39 cases. WHO objective evaluation standard, efficacy evalulation of solid tumor metastasis and curative effect standard grading of pain, anticancer agent toxicity classification standard, Karnofsky standard were used for evaluating and analyzing the patients with primary lung tumor, bone metastasis, degree of pain, adverse reactions and functional status (once before and after the treatment). Results The efficiency rate of primary lung tumor, the efficiency rate of bone metastasis, the total effective rate of pain relief and the improvement rate of functional status (Karnofsky score increased by 10 points or more)in the radiotherapy combined group and chemotherapy combined group were 82.05 % (32/39) vs. 79.49 % (31/39), 48.72 % (19/39) vs. 51.28 %(20/39), 82.05 % (32/39) vs. 84.62 % (33/39), 66.67 % (26/39) vs. 71.79 % (28/39) respectively, and the differences were not statistically significant (the values of x2 were 0.224, 0.237, 0.195, 0.259 respectively, all P> 0.05); Although the two groups showed low-grade fever, bone marrow suppression, esophagitis, liver and kidney damage, gastrointestinal reactions and other adverse reactions, the adverse reactions of two groups were close to [28.21 % (11/39) vs. 30.77 % (12/39)] (x2 = 0.314, P> 0.05). Fortunately, these reactions were controlled well after symptomatic treatment. Conclusion ZA combined with radiotherapy or chemotherapy is a safe and effective way for bone metastasis of NSCLC, which should be taken based on the individual condition of the patients.

Objective To assess the value of pulmonary vascular permeability index in differentiating acute lung injury (ALI) from cardiac pulmonary edema. Methods Critically ill patients with acute pulmonary edema were included from May, 2004 to September, 2008. Patients were divided into two groups, the ALI group and the cardiac pulmonary edema group (C group). Pulmonary vascular permeability index (PVPI) , intrathoracic blood volume (ITBVI) were determined by pulse indicator continuous cardiac output(PiCCO) system. Results ( 1 ) Thirty-four patients were enrolled, 22 cases in ALI group and 12 cases in C group. (2) The PVPI in patients of ALI group (2.7 ± 1.4) was higher than that of C group (1.9 ±0.6 ;P<0.05). EVLWI and ITBVI did not have the significant difference between the two groups (P >0. 05). (3) PVPI was positively correlated with EVLWI(r = 0. 762) , negatively correlated with PaO2/ FiO2(r= -0.478). (4)ARDS was diagnosed in 13 cases, including 8 pulmonary cause(ARDSp) and 5 extra-pulmonary cause ( ARDSexp). PVPI, EVLW/ITBV and EVLWI of patients with ARDSexp were obviously higher than those with ARDSp. Conclusions PVPI may be useful for differentiating the types of pulmonary edema in the critically ill.

Objective To describe our experience in laparoscopic radical prostatectomy (LRP)for incidental prostate cancer after TURP. Methods From April 2007 to July 2010, 5 patients with incidental prostate cancer after TURP were treated with a mean age of 73 years. The patients underwent LRP (2.8± 1.1) months after TURP. Results The five cases of LRP were performed successfully, with 1 case of transperitoneal approach and 4 cases of extraperitoneal approach. Mean operation time was (227.6±38.4) min, mean blood loss was (130±152.5) ml, and the mean follow-up was (16.1 ± 15.9) months. All five patients survived, and their urinary function was good without any incontinence. Conclusions Previous TURP represents a technical challenge when performing LRP, but highly skilled surgeons trained to perform LRPs can handle it.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5% of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P<0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score > 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P < 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1% of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2%of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

Objective To investigate the potential role of angiotensinⅡ(AngⅡ)-angiotensinⅡreceptor 1 (ATRI) pathway on inflammatory activation in the lung of rats. Method Twenty four Sprague-Dawley rats were randomly divided into four groups: control group, Ang II group, AngⅡ+losartan group and losartan group. Lung wet/dry weight (W/D) was recorded to assess lung injury. The total lung homogenates were prepared to detect nuclear factor-kappa B (NF-?B) activation by electrophoretic mobility gel shift assary (EMSA), tumor necrosis factor (TNF)-?mRNA expression by reverse transcription polymerase chain reaction (RT-PCR), myeloperoxidase (MPO) and malondialdehyde (MDA) by colorimetry. Plasma yon Willebrand Factor (vWF) were assessed by enzyme-linked immunosorbent assay (ELISA). Meanwhile, pathological changes were examined under optical microscope. Results Histologically, alveolar edema, hemorrhage, and massive inflammatory cell infiltration were observed in AngⅡgroup, but not in control group and losartan group. Compared with AngⅡgroup, histological injury was lesser in AngⅡ+ losartan group. In AngⅡgroup, lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF were markedly higher than those in the other three groups. There were not significant differences of lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF in control group, AngⅡ+ losartan group and losartan group. Conclusions Systemic infusion of AngⅡcould up- regulate inflammatory mediator expression and induce lung injury in rats. AngⅡ, acting mainly through ATRI, induced inflammatory activation in the lung of rats.

OBJECTIVETo analyze the epidemiological characteristics of occupational diseases in Guangzhou City, China in 2001 - 2010, and to provide a scientific basis for the prevention and control of occupational diseases.
METHODSStatistical analysis was performed on the reported data on the occupational diseases in Guangzhou from 2001 to 2010.
RESULTSA total of 380 cases of occupational diseases (37 types,8 classes) were diagnosed and reported in 2001 - 2010. The three most frequent diseases were occupational poisonings (48.9%), pneumoconiosis (20.0%), and occupational ear, nose, and throat (ENT) diseases (18.7%). In the cases of occupational poisonings, 25.3% suffered from acute occupational poisonings, especially the poisoning by dichloroethane (19.1%), and 74.7% suffered from chronic occupational poisonings, mainly caused by lead (38.8%), benzene (37.4%), and n-hexane (18.0%). The cases of silicosis accounted for 77.6% of all cases of pneumoconiosis. The cases of noise-induced deafness accounted for 97.2% of all cases of occupational ENT diseases. Patients with occupational diseases were reported in 13 districts of Guangzhou, mostly in Panyu (18.9%), Tianhe (13.2%), Baiyun (12.9%), and Liwan (11.1%). All the cases occurred in 19 industries, mainly including light industry (27.1%) and machinery industry (23.7%). Of all cases, 29.5% were in the public sector, 40.3% in the private sector, and 30.3% in the foreign-funded enterprises and those funded by businessmen from Hong Kong, Macao, and Taiwan. The ratio of male to female cases was 15:4. The mean age of onset was 42.2 ± 10.9 years. The average speed of development of occupational diseases was 134.0%, and the average growth rate was 34.0%.
CONCLUSIONThe incidence of occupational diseases tends to increase year by year, with younger age of onset and shorter history of exposure in patients. The occupational poisonings caused by lead, benzene, n-hexane, and dichloroethane, silicosis, and noise-induced deafness seem to be the main occupational hazards in Guangzhou, China. Occupational diseases occur in all districts of Guangzhou and in various industries. The private sector and small enterprises should be the focuses of occupational health supervision.
