Objective The objective of this study was to explore the difference factors for PHC patients by transcatheter arterial chemoembolization of different age groups of senior people in China and support reference for individualized intervention by clinical medical workers.Methods 153 cases of PHC patients by TACE were selected by convenience sampling method from October 2013 to June 2014.The data were collected using general data questionnaire,Health Promotion Strategy Scale,QOL-LC,Memorial Symptom Assessment Scales and Social Support Scale to evaluate the physical,psychological and social aspects of the PHC patients.We divided the patients into young,middle-aged and elderly groups.Single factor and multiple factors regression analysis were used to compare the status and influencing factors.Results Psychological function,value of blood AFP,marital status entered the model and were self-care efficacy and correlated factors of young-aged patients,which could explain 50.6％ of the total varience.Physical symptoms,exploitation degree of support and intervention treatment times entered the model and were self-care efficacy and correlated factors of middle-aged patients,which could explain 47.8％ of the total varience.Symptom distress,degree of cuhural and psychological function entered the model and were self-care efficacy and correlated factors of elderly-aged patients,which could explain 42.4％ of the total varience.Conclusions The self-care efficacy were low in all ages of PHC patients by TACE,it is associated with a variety of factors.Doctors and nurses should pay more attention to the self-care efficacy for PHC patients by transcatheter arterial chemoembolization with different age groups.Also we should evaluate and make well-targeted policies and personalized inter-ventions to promote self-management self-efficacy.

To study the expression of some protooncogenes in burn wounded skin tissue. Methods: The protooncogene expression was analysed by mRNA dot blot hybridization,autoradiography and densitermeter. Results: Thermal injury induced C-myc, C-myb, C-jun and C-sis mRNA expression. How-ever, those four protooncogenes showed different expression models. Expression of C-myc and C-jun in-creased at d 1, and peaked 1 and 3 d postburn, respectively. Expression of C-myb and C-sis increased 3and 5 d, and peaked 10 d after thermal injury. Conclusion: Thermal injury can induce some protooncogeneexpression which sh0wed temporal order and well controlled manifestation. Those results suggest thatthose four protooncogenes are involved with the repair process as a regulator.

Vascular endothelial growth factor (VEGF) plays an important role in tissues angiogenesis. The adaptation of animals to hypoxic environment is relative to the microvessel density (MVD) in tissues. To further explore the adaptation mechanisms of plateau zokor (Myospalax baileyi) to the hypoxic-hypercapnic burrows, the VEGF mRNA and the MVD in cerebral tissues of the plateau zokor were studied. Total RNA was isolated from liver, and VEGF cDNA was obtained by RT-PCR, then the VEGF cDNA was cloned and sequenced. The coding sequence of plateau pika (Ochotona curzniae), rat (Rattus norvegicus) and mouse (Mus musculus) VEGF cDNA are obtained from GenBank, and the nucleotide and amino acid sequence homology of plateau zokor VEGF cDNA coding sequence with that of plateau pika, rat and mouse were analyzed and compared by using of bioinformatics software. The VEGF mRNA was detected by real-time PCR, and the MVDs in cerebral tissues of the plateau zokor, plateau pika and Sprague-Dawley (SD) rat were measured by immunohistochemical staining. The results showed that the open reading frame of the plateau zokor VEGF was 645 bp, and the coding sequence of the plateau zokor VEGF cDNA shared 92.1%, 93.6% and 93.8% nucleotide sequence homology to that of the plateau pika, rat and mouse, respectively. The deduced amino acid sequence of the plateau zokor VEGF cDNA was composed of 188 amino acids and the amino acids from 1 to 26 were signal peptide sequence. The plateau zokor VEGF188 was 90.2%, 94.9% and 94.4% homologous to that of plateau pika, rat and mouse. The level of VEGF mRNA in brain of the plateau zokor was significantly lower than that of SD rat, but there was no obvious difference in VEGF mRNA level between plateau zokor and plateau pika. The MVD in brain of the plateau zokor was markedly higher than that of plateau pika and SD rat. In conclusion, plateau zokor enhances its adaptation to the hypoxic environment by increasing the MVD. The level of VEGF mRNA in the brain of plateau zokor is lower than that of SD rat, which may be as a result of inhibition by the higher concentration of carbon dioxide in the burrow.

Objective To investigate the expression of c-kit and analyze its relationship with proliferating cell nuclear antigen (PCNA) in RCC subtypes and its clinical progression. Methods Expression of c-kit protein was retrospectively studied with immunohistochemistry in paraffin sections from 137 cases of clear renal cell carcinoma (CCRCC), 82 papillary renal cell carcinoma (PRCC), 51 chromophobe renal cell carcinoma (ChRCC). Results The positive rate of c-kit in ChRCC was 94.1%(48/51), it was statistically higher than that in CCRCC (16. 1%, 22/137) and PRCC (28.1 %, 23/82)(P=0. 001 ). In ChRCC, the positive expression of c-kit was related with TNM stages. The positive expression of PCNA was related with the grade in CCRCC and PRCC. But there was no relationship between PCNA expression and grade of ChRCC. It also had the relationship with the metastasis in CCRCC. Conclusions The expression of c-kit in ChRCC is higher than in other subtype of RCC, and associated with tumor local progression. That makes c-kit as a helpful marker to discriminate different subtypes of kidney cancer.

AIM: To evaluate the safety of the laser peripheral iridoplasty ( LPIP ) for the early-stage chronic primary angle-closure glaucoma ( ECPACG) .
METHODS:Sixty-five eyes of 36 patients with ECPACG received LPIP. At preoperative and postoperative, patients were examined with intraocular pressure ( IOP ) , anterior chamber, optical coherence tomography ( OCT) , visual acuity, visual field, fundus and complications. The mean follow-up was 18. 2±6. 7mo (ranged 12~24mo).
RESULTS: The preoperative average IOP were 23. 8±5.6mmHg, postoperative 1wk, 1, 3, 6, 12mo and in the last follow-up time the average IOP were 18. 7±3. 8, 17. 9±3. 2, 17. 6±3. 5, 18. 4±3. 7, 18. 6±3. 7, and 18. 6±7. 8mmHg. There was statistical difference comparing with preoperative (P<0. 05, decreasing average 6. 5±3. 1mmHg compared with the preoperative, the difference was statistically significant (t=5. 32, P<0. 05). Postoperative 1wk, 1, 3, 6mo, the trabecular-iris angle ( TIA500 ) and the angle opening distance at 500μm ( AOD500 ) had the statistical difference comparing with preoperative ( P <0.05). At Postoperative 1a and the last follow-up time, the TIA500 and AOD500 did not have statistical difference comparing with preoperative (P>0. 05). The postoperative visual acuity, visual field, fundus had not changed. There were no complications found.
CONCLUSION:LPIP is safe, and has the short time effect in the treatment of ECPACG. With elapse of time, the effect of LPIP is weakened. We can repeat the treatment.

Objective To evaluate the efficacy and quality of life of segmental bowel resection for bowel endometriosis. Methods Totally 62 symptomatic patients with bowel endometriosis undergoing segmental bowel resection were recruited. A visual analogue scale (VAS) and the 36-item short form health survey (SF-36) questionnaire were administered before and at least 1 year after surgery, respectively. Pregnancy rates were also recorded. Results Sixty-two patients in total underwent follow-up ranging from 12 to 74 months. All patients complained of obvious pain symptoms, including dysmenorrhea, dyspareunia, pain on defecation and chronic pelvic pain. The relief of dysmenorrhea (2.9 ± 2.2 versus 7.5 ± 2.9), dyspareunia (0.7 ± 0.5 versus 4.3 ± 2.2) and pain on defecation (1.6 ± 0.7 versus 7.3 ± 1.9) after surgery was statistically significant (all P<0.01). The scores for all 8 domains of the SF-36 questionnaire were significant improved after segmental bowel resection (all P<0.01). The complication rate was 45% (28/62), including 18 cases of urinary retention, 4 rectovaginal fistulas, 2 cases of vaginal dehiscence, and 1 case each of thrombogenesis, pelvic abscess and general peritonitis. All of the patients with complications recovered well throughout follow-up. The postoperative pregnancy rate of the previous infertile patients was 6/10. Among the 6 gestational cases, 2 had labour, 2 underwent caesarean sections, one had a spontaneous natural abortion, and one underwent uterine curettage. Conclusion Segmental bowel resection could significantly relieve pain and improve quality of life for patients with bowel endometriosis.
