The therapeutic approaches for non-small cell lung cancer (NSCLC)patients with solitary bone metastases include surgery,radiotherapy,chemotherapy and so on.Recently,molecular targeted therapy such as the Denosumab has become a new option.Though there are so many options,the outcomes of the NSCLC with bone metastases are not so good.But for those with solitary bone metastases,radical treatment is necessary to improve the survival time and prognosis.

Background Recently,small incision lenticule extraction (SMILE) procedure is used to correct myopia.The clinical safety and efficiency of SMILE have been approved,but its predictability to corneal ablation depth is brought into focus.Objective This study was to compare the predictability of ablation depth in central cornea between SMILE and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia.Methods A nonrandomized controlled clinical study was performed.Two hundred and seventy eyes of 135 myopic patients who were going to receive corneal refractive surgery were included in Beijing Tongren Hospital from October 2015 to May 2016.SMILE and FS-LASIK were performed on 138 eyes of 69 patients and 132 eyes of 66 patients matched in demography respectively under the informed consent.Central corneal thickness was measured by RTVue FD-OCT before and 1 week after surgery.The refractive power,actual ablation depth (difference of central corneal thickness before and after surgery) and central corneal cutting error (difference between theoretically expected ablation depth and real ablation depth) were intergrouply compared,and the correlation of real ablation depth with theoretically expected ablation depth was assessed.Results No significant difference was found in spherical power,astigmatic power and spherical equivalent after surgery between SMILE group and FS-LASIK group (t =-1.826,-1.405,-1.420,all at P＞0.05).The actual ablation depth was (76.96± 15.27)μm in the SMILE group,which was significant lower than (96.76± 16.52) μm of theoretically expected ablation depth (t =-23.016,P ＜ 0.01);however,there was no significant difference in the FS-LASIK group between actual and expected ablation depth ([77.92 ± 18.69] μm versus [77.42± 15.60] μm) (t =-0.604,P =0.547).The central corneal cutting error was (20.55 ± 8.51) μm in the SMILE group and (7.17±5.97) μm in the FS-LASIK group,showing a significant difference between them (t=14.950,P＜0.01).The positive linear correlations were seen between actual and expected ablation depth in both SMILE group and FS-LASIK group (r=0.799,0.867,both at P＜0.01).The actual ablation depth was increased over expected ablation depth,with the regression equations of Y=3.892+0.749X in the SMILE group and Y=3.443 + 0.957X in the FS-LASIK group.Conclusions The actual corneal ablation depth is less than expected corneal ablation depth in SMILE procedure,while in FS-LASIK procedure,the actual corneal ablation depth appears to be consistent with the expected one,inferring a good predictability in corneal ablation depth in FS-LASIK surgery.

[Summary] The characteristics ot clinical data and relevant inspection (quantitative sensory and electrophysiological studies) in 5 patients hospitalized with acute painful neuropathy following rapid glycaemic control with insulin from 2010 to 2012 in our hospital were analyzed.The results showed that 5 patients were all males,aged 31-49 years,with lower body mass index,and diagnosed as latent autoimmune diabetes of adults (LADA) or type 2 diabetes.Glycaemic control was poor before application of insulin.When insulin was used,the hyperglycemia was rapidly corrected in a short time,with recurrent episodes of hypoglycemia during insulin treatment.The painful neuropathic symptoms appeared within 2-4 weeks after application of insulin,and were relieved partially or completely after 2-6 months.Neuropathic symptoms manifested as tingling and tenderness,with worsening during night and after insulin injection.The neuropathic symptoms were not significantly alleviated after application of neurotrophic drugs such as methycobal,protogen,and prostaglandin.These patients often suffered from severe anxiety.Nerve electromyogram examination showed slowed or normal motor conduction velocity of tibial and fibular nerves,and normal feeling threshold.

OBJECTIVE: To present a new approach for the research of effective components extracted from compounds of traditional Chinese medicine and their action mechanisms by high-throughput screening assay. METHODS: We observed the anti-oxidation activities of 240 sequential components (L1-L120 and A1-A120) extracted from Xiaoxuming Recipe, the effects of these components on SH-SY5Y cells with H(2)O(2)-induced and L-glutamic acid-induced damages and the levels of resting calcium ion in neurocytes of rats. RESULTS: Some components (L1-L40, A100-A120) extracted from Xiaoxuming Recipe had the corresponding effects listed above. The combination of these components was regarded as the groups of effective components of Xiaoxuming Recipe in treating sequelae resulting from brain ischemia. CONCLUSION: Xiaoxuming Recipe has protective effect on brain-ischemia-induced damages through the actions of multiple components with multiple targets.

A cidithiobacillus ferrooxidans is a chemolithotrophic microorganism capable of using ferrous ions and sulphides as energy sources. This microorganism has an important role in the bioleaching of minerals. During this process, the bacteria are normally subjected to several stressing conditions, such as temperature changes, lack of nutrients or pH changes, which may affect the efficiency of the bacterial action. SELDI is a recent technology that allows for high-throughput proteomics studies. The Protein Chip SELDI technology was used to generate comparative protein profiles of A c idithiobacillus ferrooxidans grown under phosphate starvation or normal condition additionally adding Fe2+ as energy resource. There were 13 significantly differential expressed protein's peaks found by using SELDI Protein Chip technologies, which made a solid foundation for further isolation these low molecular proteins by adopting technologies such as HPLC etc.

Background Keratectasia after laser in situ keratomileusis (LASIK) is a rare but severe complication,which threatens the visual acuity and corneal strength.Corneal collagen crosslinking (CXL) is a new therapy that increases the security and decreases the risk of complication.However,the effectiveness and safety of LASIK-CXL is still need to be concerned.Objective This study was to evaluate the safety of LASIK-CXL for myopia and astigmatism with thin cornea.Methods A prospective cohort study was designed.A total of 128 eyes of 64 patients with thin corneal and myopic astigmatism enrolled in Beijing Tongren Eye Center from January 2014 to January 2015.The patients were assigned to LASIK group (74 eyes of 37 patients) and LASIK-CXL group (54 eyes of 27 patients).Refractive surgery was performed by Visumax femtosecond lasrer and VISX S4 excimer laser.Eyes of LASIK-CXL group applied accelerated CXL immediately after LASIK.The follow-up was 6 months.Manifest refraction,uncorrected (UDVA) and corrected distance visual acuity (CDVA),average keratometry values (AveK),anterior segment OCT (AS-OCT),corneal hysteresis (CH) and corneal resistance factor (CRF) were examined before and after operation.This research passed through Ethics Committee of Beijing Tongren Hospital.Results The spherical equivalent (SE) of the LASIK group and LASIK-CXL group were (-6.49 ±2.41)D and (-6.97 ±2.41) D before operation and decreased to (-0.68 ±0.88) D and (-0.75 ±0.94) D 6 months after operation.The UDVA (LogMAR) was 1.18±0.28 and 1.05±0.38 before operation and elevated to-0.06±0.09 and-0.03±0.186 months after operation in the LASIK group and LASIK-CXL group.The preoperative AveK values were (44.37 ±1.46) D and (44.47± 1.50)D in the LASIK group and LASIK-CXL group and reduced to postoperative (39.30±2.06) D and (38.66± 1.80) D.The preoperative SRI of LASIK group and LASIK-CXL group were 0.25 ±0.21 and 0.24±0.22,which increased to 0.29±0.24 and 0.28±0.24.The SAI values were 0.36±0.16 and 0.39±0.15 before operation,which increased to 0.57 ±0.31 and 0.75 ±0.376 months after operation,and the SAI value of the LASIK-CXL group was significantly higher than that of LASIK (F =10.220,P--0.002).CRF values of LASIK and LASIK-CXL were (8.44±1.44)mmHg and (8.63±1.35) mmHg in preoperation,which decreased to (5.74±1.31) mmHg and (6.25± 1.24) mmHg in postoperation.The result of LASIK-CXL was higher than that of LASIK (F=8.650,P =0.040).CH values were 8.78 ± 1.51 and 8.69 ± 1.62 in preoperation,which decreased to (7.23 ± 1.08) mmHg and (6.50±1.32)mmHg.The value of LASIK-CXL was lower than that of LASIK (F =5.860,P =0.017).The mean depth of demarcation line was (228.45±28.24) μm (range 165 to 310 μm) on OCT,which was presented in 45 eyes (81.82％) at 1 month in postoperation.Conclusions Accelerated CXL with FS-LASIK is effective and safe in improving visual acuity in myopic astigmatism patients with thin cornea,which also can increase the rigidity of the cornea.

Objective To investigate cartilage oligomeric matrix protein( COMP) gene mutation in a three-generation pedigree with two cases of pseudoachondroplasia, and to definitize genotype-phenotype correlation. Methods The clinical data and peripheral blood were collected from the patients with pseudoachondroplasia and their family members. All the 19 exons and their flanking sequences of COMP gene in two patients and three unaffected family numbers and 50 unrelated individuals were analyzed by PCR amplification and direct sequencing. Results The proband, a 6-year-old girl presented with typical clinical features of pseudoachondroplasia, including disproportionate short limb dwarfism, staggering gait, double genu varus deformity, and wider clinical and imaging long bone metaphysis. The 33-year-old father showed a similar manifestation including disproportionate short limb dwarfism and double genu varus deformity, and was performed correcting operation on lower limbs for double genu varus at the age of 10 years. DNA sequencing analysis of the COMP gene revealed a del mutation ( c. 1417 1419delGAC)in exon 13 in two patients with pseudoachondroplasia, but not in the other unaffected members from the pedrgree and 50 control subjects. Conclusion A del mutation c. 1417 1419delGAC of COMP gene may contribute to the disease in the pedigree.

OBJECTIVETo investigate the burden of infectious disease of the Chinese population in 1990 and 2010 and changing pattern in the past 20 years.

METHODSResults of the Global Burden of Disease Study 2010 (GBD 2010) were used to demonstrate the burden of infectious disease of the Chinese population in 1990 and 2010 and changing pattern from 1990 to 2010 by gender and age groups, including indicators of incidence, mortality, years of life lost due to premature mortality (YLL), years lived with disability (YLD), disability-adjusted life years (DALY), and their age-standardized rates using data of the 2010 National Census as a standard population.

RESULTSIn 1990 incidence, standardized incidence rate, mortality, standardized mortality rate, DALY, standardized DALY rate, YLL, standardized YLL rate, YLD, and standardized YLD rate of infectious disease in China were 3 067 469 200 cases, 242 669.34 cases/100 000, 824 300 cases, 72.27 cases/100 000, 58 937 700 person-years (PYRS), 3 992.85 PYRS/100 000, 46 504 100 PYRS, 2 932.99 PYRS/100 000, 12 433 600 PYRS, and 1 059.86 PYRS/100 000, respectively. All the aboved indicators were declined from 1990 to 2010, in 2010 they were 3 065 985 800 cases, 224 351.66 cases/100 000, 388 600 cases, 30.74 cases/100 000, 19 492 200 PYRS, 1 440.75 PYRS/100 000, 12 045 700 PYRS, 891.87 PYRS/100 000, 7 446 500 PYRS, and 548.89 PYRS/100 000, respectively. When 2010's indicators were compared to those in 1990, the rates of increase of incidence, incidence rate, mortality, mortality rate, DALY, DALY rate, YLL, YLL rate, YLD, and YLD rate were 56.84%, -9.85%, -33.07%, -61.54%, -27.68%, -58.42%, -32.46%, -61.17%, -16.75%, and -52.13% for 50-69 age group; for ≥ 70 age group, 57.90%, -5.86%, 7.41%, -36.12%, -5.00%, -43.51%, -5.14%, -43.59%, -4.52%, and -43.2%.

CONCLUSIONSThe burden of infectious disease of the Chinese population was declined from 1990 to 2010; however, the incidence of infectious disease was increased in ≥ 50 age groups.
