Objective To study occupational hazards effects of electric welding,and evaluate protective measurements for different occupational hazards. Methods During 2008,occupational health services for 11 factories with shield carbon-dioxide arc welding work were provided,including surveillance of the work environment and surveillance of workers’health. Surveys of workers’health through various types of health examinations were carried out. Four hundred and thirty-three welding workers of 11 factories were included. Results The concentrations of 17 welding fume samples and 6 manganese dioxide samples were over the released limits of national standard,the maximum was 5.5,1.6 times of the limit respectively. The exceeding standard rate. of welding fume had positive correlation with the density of welding equipment(r= 0.72,P=0.01) and negative correlation with the ventilation area(r =-0.63,P =0.04) .The examination results showed that nobody suffered occupational diseases or occupational contraindications. Conclusion For the environmental risk factors existed in the electric welding operation site,more attention should be paid to the potentially occupational adverse effects of electric welding.

Objective To investigate the basic perceptions, attitudes and needs towards delirium among ICU professionals in Shandong province, so that to help the ICU supervisors design target training for ICU professionals. Methods A survey was employed utilizing a self-designed questionnaire among 917 ICU professionals(doctors and nurses) from 62 hospitals in Shandong province. Results The score of ICU professionals′ basic perception and behavioral attitude concerning ICU delirium were (24.56 ± 6.36) and (19.00 ± 3.01) points respectively. The score had significant positive correlation and indicates statistic significance (r=0.53, P<0.01). Academic, work experience and title had influence on the score of basic perception (F=14.49, 26.25, 40.16, P<0.05), work experience, category of ICU, title and category of hospital were the effect on the score of behavior and attitude (F=11.87, 8.64, 6.55, P<0.05;t=4.81, P<0.05). The lower rate of correct responding to knowledge of ICU delirium were as follows:the correct rate of delirium in ICU of typing to 56.92%(522/917); the clinical manifestations of ICU delirium accuracy 65.32%(599/917); andrisk factors for delirium in ICU of the correct rate for 70.34%(645/917).ICU professionals acquire knowledge pertaining delirium mainly through lectures, conferences, knowledge brochure , exchange of experience. Conclusions The ICU professionals in Shandong province have less knowledge on ICU delirjum.ICU management should recognize the importance of ICU delirium to strengthen the training of relevant knowledge, enhance delirium management, ensure the patient's safety and improve the prognosis of patients.

OBJECTIVE: To observe the repairing effects of bone marrow transplantation with nerve tissue committed stem cell (NTCSCs) on experimental rats with injury of noise-induced hearing loss. METHOD: Guinea pigs were randomly divided into control group, noise exposure group and the transplanting group. A week after white noise exposure of 110 dB, NTCSCs and PBS were injected into guinea pigs of the noise exposure group and the transplanting group respectively. One week after noise exposure to four weeks continuous administration. ABR thresholds were measured respectively prior to the experiment, 1 week post-noise,1, 2 and 4 weeks post-drugs, The changes of cochlea hair cells were also observed by a scan electron microscope (SEM). RESULT: The ABR threshold shifts in the transplanting group were significantly fewer than that in the noise exposure group. SEM showed that hear hair of the inner and outer hair cells in noise exposure group displayed mess, fusion and imperfections. In the transplanting treatment group, the hair cells displayed slight pathological changes, there wasn't significant differents comparied with normal group. The number of OHCs were relatively stable in the normal group, while the obvious OHC loss was observed in other groups. There was significant difference among the three groups, however, the OHC loss in the transplanting group was no significantly different to that in the noise exposure (P > 0.05). CONCLUSION The bone marrow NTCSCs which had been transplanted to rat cochlea could reduce the damage of the noise on the hair cell, and thus played a role in repairing the damage of auditory nerve.

ObjectiveTo explore clinical effect and safety ofShaoyao-Gancao decoction combined withSiwu decoction for the patients with diabetic peripheral neuropathy (DPN).MethodsA total of 76 patients with DPN in our hospital from 2013 July to October 2015 were divided into control group and observation group by the random number method, 38 patients in each group. The control group were treated with conventional treatment combined with oryzanol injection, and the observation group were treated with Shaoyao-Gancaodecoction combined withSiwu decoction on the basis of control group. Both groups were treated for one month. The level of FPG, 2 hPG, HbAlc, TC, TG, LDL-C and HDL-C was detected respectively before and after treatment. The whole blood viscosity and plasma viscosity was detected with LBY-N6A self-cleaning rotary viscosimeter. The red blood cells deposited and platelet aggregation rate were tested with Winchester points vascular method and turbidimetric method, respectively.The leg nerve and sural nerve of nerve conduction velocity (nerve conduction velocity, NCV) were determined with electromyography, at the same time the clinical curative effect was evaluted.ResultsTotal effect rate of observation group was 89.5% (34/38), which was significantly higher than the control group 71.1% (27/38), and the difference was statistically significant (χ2=4.070,P=0.044); After treatment, the levels of FPG (6.12 ± 0.38 mmol/Lvs.6.58 ± 0.52 mmol/L, t=4.403), 2 hPG (7.83 ± 0.82 mmol/Lvs. 8.41 ± 0.93 mmol/L,t=2.884), HbAlc (6.27 ± 0.52%vs. 6.82 ± 0.64%, t=4.112) in the observation group were lower than those in the control group (P<0.05). The levels of TC (4.73 ± 0.83 mmol/L vs. 5.11 ± 0.64 mmol/L,t=52.235), TG (1.83 ± 0.35 mmol/Lvs. 2.03 ± 0.41 mmol/L, t=2.287) and LDL-C (2.91 ± 0.54 mmol/Lvs. 3.25 ± 0.58 mmol/L,t=2.645) in the observation group were lower than those in the control group (P<0.05), and the HDL-C (1.47 ± 0.33 mmol/Lvs. 1.26 ± 0.31 mmol/L,t=-2.859) in the observation group was higher than than that in the control group(P<0.05). The level of whole blood specific viscosity (10.16 ± 2.12 mPa?svs. 11.33 ± 2.51 mPa?s,t=2.195), plasma viscosity (1.24 ± 0.25 mPa?svs. 1.62 ± 0.37 mPa?s,t=5.246), red blood cell volume (0.31 ± 0.16L/Lvs. 0.42 ± 0.08 L/L,t=3.791) and platelet aggregation rate (50.21% ± 8.03%vs. 54.16% ± 7.82%,t=2.172) in the observation group were significantly lower than those in control group (P<0.05). The tibial nerve velocity (45.22 ± 3.20 m/svs. 38.26 ± 5.19 m/s,t=-7.037) and the common nerve velocity (43.22 ± 6.34 m/svs. 36.23 ± 4.81,t=-5.415) in the observation group were as significantly higher than those in control group (P<0.05).ConclusionsThe Shaoyao-Gancaodecoction combined withSiwu decoction could improve the state of blood sugar, blood lipid and blood rheology of patients with DPN, and improve nerve transfer speed of leg nerve and sural nerve, the curative effect is better than conventional western medicine therapy alone.

Therefore, the significance of “nine needles” is evident. This article expounded “nine needles” from the following six aspects:the origin, the name, the types, the functions, the use and the application, with a purpose to standardize the contents of “nine needles”, and analyse the connotation.

Immune-checkpoint blockers(ICBs)have been well received in a variety of tumors,and the quality of patient life has improved significantly.However,the reasons why not all patients treated with ICBs benefit from lesion control,symptom improvement,and survival time.Many patients are resistant to the first time when they have been using ICBs for a period of time.This is a clinical challenge.This review lists possible causes of primary drug resistance and acquired resistance to ICBs.The primary resistance is associated with several mechanisms,including tumor microenvironment,cancer cells themselves and other related factors.The acquired resistance includes nonclassical immunoprecipitation molecules secondary overexpression,abnormalities of antigen presenting signal pathway and dysfunction of T cell activation killer.Finally,we have described a variety of possible new combination of treatment,including combined radiotherapy and chemotherapy,and combined targeted therapy with other measures.

Objective To observe dynamically the location and time of attachment and invasion of Toxoplasma gondii tachyzoites to murine intestinal mucosa by chromogenic in situ hybridization targeting SAG2 mRNA. Methods Thirty 7- to 8-week-old BALB/c mice were randomly divided into experiment group(24 mice)and control group(6 mice). Each animal in the experiment group was given 2?104 tachyzoites of RH stain in 0.2 ml PBS by intragastric administration and that in the control group was given 0.2 ml PBS. Four mice in the experiment group and one in the control group were sacrificed at 15 min,30 min,1 h,2 h,4 h and 8 h after infection,respectively,and paraffin sections of duodenum,jejunum and ileum were prepared to perform the in situ hybridization with Dig-labeled oligonucleotide probe complementary to SAG2 mRNA of T. gondii. Results Tachyzoites were found on the striated border of small intestine epithelial cells (absorptive cells,goblet cells and endocrine cells),in or between two absorptive cells or in the lamina propria. At 15 min-2 h after infection,there was significant difference in the number of attachment on jejunum and ileum (P
