Objective To know the effects of dietary intervention for constipation of patients with lung cancer when cured by chemotherapy. Methods Divided 62 patietns with lung cancer who had post-chemotherapy constipation and had accepeted 2-course of chemotherapy into the control group and the in-tervention group randomly, there were 31 cases in the each group. Dietary intervention was used in the in-tervention group, while routine nursing cares was used in the control group according to patients owns habits. Compared the incidence condition of constipation between the two groups. Results The incidence rate in the intervention group was 19.4%, which had significant lower than the 87.1% in the control group. Conclusions Dietary intervention can effective prevent or release the constipation for patients with lung cancer when cured by chemotherapy.

Helicobacter pylori (H. pylori) is one of the most common pathogens in human and it is closely related to gastrointestinal diseases. It is essential for us to understand the transmission process of H. pylori to prevent its spreading. The oral cavity has been proposed as a reservoir for gastric H. pylori, which has been detected by culture and polymerase chain reaction (PCR) in both dental plaque and saliva. Some researchers have proposed H. pylori in oral cavity may play an important role in its transmission and reinfection. Oral-oral or fecal-oral transmission are thought to be the most possible transmit way. This review will discuss the evidence for the role of the oral cavity in the transmission of H. pylori, the difficulties encountered in addressing this topic and possible directions for future research. Oral H. pylori may also play a role in the diagnosis and prevention of deceases related to H. pylori such as gastritis, gastric ulcer and gastric carcinoma. The recent progresses in this area are also reviewed. Moreover, we also discussed the relationship between oral H. pylori and oral deceases like periodontal disease and oral ulcer.

Objective To study the relationship between diabetic retinopathy(DR) and Landsteiner-Wiener,Indian blood group genes.Methods Peripheral blood samples were collected from 50 DR patients,and 160 unrelated volunteer blood donors(the control).CDNA,including LW gene generated by reverse transcription polymerase chain reaction(RT-PCR),was subjected to sequence analysis,and the genomic DNAs,extracted from each sample,were sequenced directly for LW gene and IN gene.Woolf method was used for calculating relative risk(RR).Results In the 160 control samples,there was A at the nt380 locus in Exon1 of the LW gene,which were genotyped as LWa;and there was G at the nt252 locus in Exon2 of the IN gene,which were genotyped as INb.All the 53 samples from DR patients were LWa homozygous genotypes and all INb homozygous genotypes.Conclusion These two candidate genes are not associated with the incidence of DR.

Objective To investigate the residual risks of transfusion-transmitted HBV/HCV/HIV in current donor screening system of Qingdao area.Methods After the ELISA tests(HbsAg,anti-HCV,anti-HIV) were performed,NAT tests of HBV-DNA,HCV-RNA,and HIV-RNA on plasma samples were conducted.Such specimens as have discrepant ELISA and NAT results(N+/E-,or N-/E+) were subject to further follow-up confirmation tests.Results Among 12000 donor samples,no sample with anti-HCV(-)/HCV-RNA(+) or with anti-HIV(-)/HIV-RNA(+) was detected.However,2 individuals were detected as HBsAg(-)/HBV-DNA(+).One donor had negative ELISA test results in HBsAb,HBeAg,HBeAb,and HBcAb at the first screening.But the HBsAg,HBeAg and HBcAb were confirmed positive along with HBV-DNA after 11 weeks.The other donor was negative for HBsAb,HBeAg,and HBeAb but positive for HBcAb.Follow up tests after 3 weeks indicated the same serological results,with a similar low viralload at about 1000 IU/mL.Conclusion Due to the window period and occult HBV infection,current blood donor screening system has some residual risks of transfusion-transmitted HBV.NAT and HBcAb tests should be implemented to reduce the residual risks of transfusion-transmitted HBV.

ObjectiveTo evaluate the clinical effects of surgery using scar flap in situ combined with radiotherapy in 24 hours in the restorative treatment of keloids on the auricula and the preventive effects of the therapy in the recurrence of the keloids.MethodsThe scar flap in situ was designed,its size was large enough for covering the wound of the keloid on the auricula.The keloids along the designed lines were excised using local anesthesia,the flap was clipped into the one with even thickness and suitable size which covered the wound tensionlessly to ensure that the scar flap in situ survived well,and then the wound was bandaged with pressure and drained when necessary.18-24 hours after the surgery the wound was perpendicularly irradiated by the 5 MeV high energy electron beam (beta particle) of the Siemens Primus linear accelerator.After the dressing change was performed and the drain was removed; the wound was exposed to the irradiation,3-4 Gy segmentation dose per time,and the wound was then bandaged with pressure.The radiation was performed every two days and four times altogether with a total irradiation dose of 12-16 Gy.Stitches were removed 8-10 days after the surgery.ResultsThere were no avascular necrosis in the 25 scar flaps in situ and the wounds were all primary healing with normal color and fine appearance.All the patients were satisfied with the surgery.There was no recurrence of the 23 patients during the 8 to 42 months' follow-up,but there was a tendency to recur in 2 patients after 4-6 months,and the recurrence was controlled after the beta methasone was locally injected for 2-4 times.ConclusionsIt is not necessary to harvest the flaps on the other sites applying the sear flap in situ in the restorative treatment of keloids on the auricula,and therefore it prevents the formation of the keloids on the donor sites.Furthermore,the surgery is simple and the appearance of the auricula is fine,and it presents satisfactory clinical effects to irradiate the wound in 24 hours after the surgery.

Objective To analyze the delay in diagnosis and treatment lung cancer expressed as solitary pulmonary nodules (SPN) found by physical examination,and to discover the relative reasons and consequence for future improvement.Methods From January 2000 to August 2011,162 patients (93 males,69 females,ranging 33-82 years,median age 63.9 years) with SPN found by physical examination and diagnosed lung cancer by surgical pathology subsequently were enrolled to this study.Depending on the interval between the date when finding SPN and the date of surgery,these cases were divided into 6 groups,including the group with interval less than 1 month (74 patients),1-3 months (48 patients),3-6 months (10 patients),6-12 months (7 patients),12-24 months (8 patients),and more than 24 months (15 patients).Factors which impact the delay interval between SNP finding and surgery were discussed.The change of tumor' s diameter during observation period,and the pathological characters were also analyzed among each group.Results Of all the delay cases,30.2％ were attributed to doctor,30.9％ attributed to patients themselves,and 38.9％ attributed to hospitals.51.0％ (25/49) of the cases delayed by doctors were misdiagnosed as inflammation,16.3％ (8/49) misdiagnosed as tuberculosis,and 16.3％ (8/49)misdiagnosed as old lesions,which were three common reasons.Patients delayed more than 3 months were more likely to be related to doctor's misdiagnosis than those delayed less than 3 months[70.0％ (28/40) vs.36.8％ (21/57),x2 =10.338.P =0.001].Moreover,the possibility of SPN enlargement was positively correlated with the delay interval.In groups with delay interval more than 24 months or between 12 and 24 months,the percentage of SPN enlargement were 73.3％ (11/15) and 87.5％ (7/8) separately.The proportion of patients with stage IV disease in groups whose delay interval exceeded 12 months (13.3％ for more than 24 months and 12.5％ for 12-24 months) also significantly surpassed others groups with shorter delay interval.Conclusion There exists obvious delayed diagnosis and treatment in lung cancer initially expressed as solitary pulmonary nodules (SPN) during physical examination.Nearly 1/3 patients were delayed by doctors and half of them were misdiagnosed as inflammation.Increase of observation time could result in enlargement of SPN and advancement of disease staging.Thus,patients and doctors should pay more attention and clarify the diagnosis through surgery in less than 3 months after finding SPN,which could remarkably benefit early treatment.

Objective To investigate the expression of histone acetylated H3 and H4, methylated H3K4 and H3K9 in diffuse large B-cell lymphoma (DLBCL). Methods The expression of histone acetylated H3 and H4, methylated H3K4 and H3K9 were examined by SP immunohistochemistry technique in lymphoid tissue of 40 cases with DLBCL and 16 cases with proliferative lymphadenitis. Results The expression of histone acetylation of H3 and H4 were lower than that in proliferative lymphadenitis. Histone methylated H3K4 was lower in expression and H3K9 was in higher expression. There was a positive correlative expression between the global histone acetylation of H3 and H4, the global histone acetylation of H3, H4 and histone methylation of H3K4. Conclusion Improper modification of histone acetylations and methylations may play an important role in pathogenesis in DLBCL.
