Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

Objective To study the distribution of the specific fragment R049 of uropathogenic E. coli(UPEC) 132 in UPEC and fecal E. coli strains. Methods The specific fragment R049 was amplified by PCR from 20 UPEC strains and 40 fecal E. coli strains, and 5 genes encoding virulence factors (papC, fimH, hly, aer, cnf1) were detected from fragment R049 positive strains. Pulse field gel electronphoresis (PFGE) was applied for isolating the Xba Ⅰ restriction fragments of the genomes of fragment R049 positive strains, and then Southern blot was applied for analyzing the distribution features of the positive hybridization bands by digoxin-labeled R049 ORF probe. Results The specific fragment R049 was amplified from 8 of 20 UPEC strains (40%) and 3 of 40 fecal E. coli strains (7.5%), and statistics analysis showed significant difference (P<0.01). The specific fragment 11049 was closely related with 5 virulence factors of UPEC in the fragment R049 positive strains. Southern blot showed the sizes of positive bands were 150 kb, 15 kb and 240 kb in 3 fecal E. coli strains, 350 kb in 6 of 8 UPEC strains, and 280 kb and 25 kb in the rest two UPEC strains. Conclusion The specific fragment R049 of UPEC132 possessed the feature of clustering distribu-tion in domestic isolated UPEC strains.

Objective To characterize the changes in the dimensions during systolic and diastolic periods in the aorta with ECG-gated multi-detector CTA scans.Methods The CT angiograms of 115 patients (78 males,mean age 55.2 ± 9.4 years;37 females,mean age 60.1 ± 8.5 years) both in systolic and diastolic periods were obtained on a 64-slice ECG-gated multi-detector CT scanner.The diameters were measured at four anatomic levels of the aorta.(Level A:1 mm proximal to the innominate artery;Level B:1 mm distal to the left common carotid artery;Level C:1 mm distal to the left subclavian artery;Level D:10cm distal to the left subclavian artery).On each level,the maximal and the minimal diameters were measured both in systolic and diastolic periods.Results The paired sample t test results showed a significant difference between the systolic and diastolic diameters in all individual subjects on every level (P ＜0.001).The mean maximum diameter changes were 1.95％ (range-2.0％ to 7.0％),2.12％ (range-3.0％ to 6.0％),1.88％(range-1.0％ to 8.0％)and2.47％(range-3.0％ to 10.0％)at level A,B,C and D,respectively.The mean minimum diameter changes were 1.43％ (range-3.0％ to 5.0％),2.67％ (range-2.0％ to 11.0％),1.75％ (range-14.0％ to 9.0％)and 2.99％ (range -2.0％ to 11.0％) at level A,B,C and D,respectively.Conclusions The differences of the aortic diameters between systolic and diastolic periods are significant.The pulsatility of aorta in Chinese population may be different from published Western literature.

Objective To supply a scientific basis for standardizing the normal reference value of forced vital capacity (FVC) of Chinese younger women. Methods We studied the relationship between the normal reference value of 21767 samples of FVC of younger women and eight geographical factors in 157 areas in China. Results It was found that the correlation between geographical factors and the normal reference value of FVC of younger women was quite significant (F=5.884, P=0.000). By adopting the method of mathematical regression analysis, one regression equation was inferred: =3.146+0.00006919X1+0.01315X4-0.006966X6+0.09524X8±0.254. In the above equation, is the normal reference value of younger women' FVC (L); X1 is the altitude (m); X4 is the annual mean air temperature (℃); X6 is the annual mean relative humidity (%); X8 is the annual mean wind speed (m/s); 0.254 is the value of the residual standard deviation. Conclusion If geographical values are obtained in a certain area, the normal reference value of FVC of younger women in this area can be obtained by using the regression equation. Furthermore, according to the geographical factors, China can be divided into eight regions: Northeast China Region, North China Region, Shanxi-Shaanxi-Inner Mongolia Region, middle and lower reaches of the Yangzte River Region, Southeast China Region, Northwest China Region, Southwest China Region, and Qinghai-Tibet Plateau Region.

Objective To observe the injury of high intensity focused ultrasound combined with radiotherapy (RT) to the pancreas,the unintended abdominal tissues and organs of swine in vivo.MethodsAccording to the criterion to grade the gross and histological injury of the pancreas and the unintended tissue,the scores of injury between the groups to get the data of safety and feasibility of high intensity focused ultrasound(HIFU)combined with RT were compared.Results There was a better tolerance in each group and no fatal complication was observed.For the pancreas there was significant difference for the combined group compared with the other groups.For the unintended target tissue there was no significance difference except the control group with the other groups.Conclusion HIFU combined with RT can increase the injury to the pancreas of the swine compared with HIFU alone; while there was no increase for the injury to the unintended target tissue.The main toxicity of combination treatment is the toxicity of RT and can be tolerated by the animals.If the HIFU treatment is strictly controlled,the combination of HIFU and RT is safe and feasible.

Objective:To evaluate the value and identify the prognosic factors of postoperative radiotherapy (PORT) in completely resected stage Ⅲ(pN 2) lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) wild-type who received adjuvant chemotherapy. Methods:Clinical data of 172 patients with stage Ⅲ(pN 2) EGFR wild-type lung adenocarcinoma who underwent radical resection and adjuvant chemotherapy from 2009 to 2016 were retrospectively analyzed. All patients received platinum-based adjuvant chemotherapy combining two drugs for>4 cycles, and divided into the PORT group and the non-PORT group. The survival rate was calculated by Kaplan- Meier method and log-rank test, and multivariate prognostic analysis was performed by Cox’s regression model. Results:Among 172 patients, the median overall survival (OS), 3-year and 5-year OS rates were 40 months, 55.9% and 28.3%, respectively. The median disease-free survival (DFS), 3-year and 5-year DFS rates were 17 months, 24.5% and 13.0%, respectively. DFS was significantly improved in the PORT group (29 months vs. 13 months, P=0.001), whereas OS did not significantly differ between two groups (51 months vs. 38 months, P=0.151). In subgroup analysis, DFS of patients with multistation N 2 or the number of N 2 metastases of&ge;3 or skip N 2 in the PORT group was significantly longer ( P<0.05), whereas PORT exerted no significant effect on OS ( P>0.05). Conclusions:For patients with completely resected stage Ⅲ(N 2) EGFR wild-type lung adenocarcinoma receiving adjuvant chemotherapy, PORT might increase DFS and have a trend toward longer OS. However, these findings remain to be validated by large sample size investigations.

OBJECTIVETo observe the optimal timing of operation and the therapeutic effect of endoscopic optic nerve decompression for traumatic optic neuropathy (TON).

METHODSThe clinical records of 90 consecutive patients with TON (93 eyes) after head and/or maxillofacial trauma from April 1998 to March 2007 were reviewed and analyzed. All patients were either unresponsive or intolerant to medication before they underwent intranasal endoscopic optic nerve decompression. The time interval between the injury and operation ranged from one day to 97 days (median 5.5 days). Among the 93 eyes, there were 71 eyes with no visual acuity before operation and 22 eyes with residue visual acuity, including light perception in 1 eye, hand movement in 5 eyes, counting fingers in 13 eyes, 0.04 in 1 eye, and 0.1 in 2 eyes. Duration of follow-up ranged from 6 days to two years (median 8 days).

RESULTSAfter decompression, 35 patients (36/93 eyes, 38.7%) showed improvement of visual acuity, 53 patients (55 eyes, 59.1%) remained the same as before operation, while 2 patients (2 eyes, 2.2%) showed decreased visual acuity. Among patients with visual acuity beyond light perception before decompression, 68.2% of them (15/22 eyes) experienced visual improvement, whereas only 22.9% (8/35 eyes, 0.02 in two eyes) among patients who lost visual acuity immediately after injury, and 36.1% (13/36 eyes, 0.02 in five eyes) among those who lost visual acuity gradually after injury. There was a significant difference in visual improvement between group with visual acuity and group with no visual acuity (chi(2) = 11.864, P < 0.01). Among patients with no visual acuity, 41.2% of those (7/17 eyes) who underwent operation within 3 days of injury, experienced improvement in visual acuity, compared with 25.9% (14/54 eyes) for those who underwent the operation more than 3 days after injury. It was indicated that no significant difference in visual improvement between these two groups (chi(2) = 1.46, P > 0.05). When comparing different sites of fracture, the effect of surgery was the most desirable (55.6%, 10/18 eyes improved) if the fracture occurred simultaneously in both exterior and interior walls of optic canal, followed by the interior wall fracture (45.7%, 21/46 eyes). The operation was less effective if there was no fraction (20%, 4/20 eyes) or if the fracture occurred in exterior wall alone (11.1%, 1/9 eyes).

CONCLUSIONSEndoscopic optic nerve decompression is a minimally invasive procedure with no adverse cosmetic effects. Early operation is recommended for saving vision, even though visual acuity is lost immediately after injury. However, the satisfactory clinical effects of endoscopic optic nerve decompression require further study.

OBJECTIVETo investigate the availability of serum level of macrophage clony stimulating factor (M-CSF) as a marker for early diagnosis of Alzheimer's disease (AD).

METHODSThe serum levels of M-CSF in 70 patients with AD, 52 healthy controls, 22 patients with VAD (vascular dementia) were measured and the serum levels of IL-1 beta, IL-6, TNF-alpha in 32 patients with AD and 20 controls were measured as well.

RESULTSSerum levels of M-CSF were significantly elevated in patients with AD when compared with healthy controls (P < 0.01) and VAD controls (P < 0.05) respectively. At the early stage of mild dementia and middle dementia, serum levels of M-CSF were significantly elevated, but at the later stage of severe dementia, they returned to normal level. Serum levels of IL-1 beta were significantly elevated in AD patients compared with controls (P < 0.05), and serum levels of TNF-alpha and IL-6 were within the normal range in patients with AD.

CONCLUSIONSThe results suggest that serum M-CSF level may provide a convenient and sensitive means for the early diagnosis of Alzheimer's disease.
