ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

BACKGROUND: To discuss the basic theory of traditional Chinese medicine (TCM) related to stem cell for a try to offer a new combining site +for the modernization research of the basic theory of TCM.METHODS: Comparatively analyzing the characteristic of stem cells and the essence theory in TCM.RESULTS: Stem cells have the capacity for both self-renewal and differentiation and can produce the daughter cells with the same phenotype and genotype as themselves. Stem cells have the plasticity that a stem cell may differentiate into cells other than the lineages to which it is committed, and therefore, is also termed transdifferentiation. So it is of great value for stem cell application in tissue engineering, curing tissue-damaged diseases and as the vector for transgene therapy. We compared the character of stem cells with essence theory, an elementary and important part of the basic theory of TCM, and found that stem cells are related greatly to essence,according to its two origin, congenital essence and acquired essence, and four kinds of functions of essence, which are controlling reproduction,controlling growth and development, manufacturing marrow and transforming blood; nourishing and moistening the zangfu-organs. Furthermore, stem cells especially have direct connected with the congenital essence which is stored in the kidneys. Congenital essence is the reproductive essence accepted from parents. Sperm and ovum merge to be oosperm, that is just the totipotent stem cell. The connotative meanings of congenital essence include all germ plasm and the special developing message of a genus in the oosperm. Genital stem cells are in charge of the function of controlling reproduction of congenital essence. Growth and development function is related to the proliferation and differentiation of adult stem cells controlled by gene. Manufacturing marrow function has relation with bone marrow stem cells and neural stem cells (NSC) in medullary cavity in which contains bone marrow, spinal cord and brain. Dominating bones function of the kidneys is related to mesenchymal stem cells (MSC), and hematopoietic stem cells (HSC) execute the function of producing blood completely.CONCLUSION: We consider that stem cells have a close relation with the congenital essence, and we put forward a new viewpoint in this research that stem cells have the same properties of congenital essence, and they are existence formation of congenital essence in cell level.

Objective To assess the feasibility and effectiveness of transcatheter arterial embolization for the treatment of splenic artery aneurysms (SAAs). Methods Transcatheter splenic arterial embolization with coils was performed in eight cases of SAAs. The patients were followed for 3-36 months. The follow-up examinations with CT or color Doppler ultrasonic angiography were made. Results Technical success was achieved in all eight cases with no severe complications. During the follow-up period, one patient died of severe abdominal bleeding 10 months after the operation and the other seven patients remained in good condition with no occurrence of re-canalization of the lesions. Conclusion Transeatheter arterial embolization is a safe and effective treatment for splenic artery aneurysms. It is necessary to make a regular follow-up imaging study.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

ObjectiveTo investigate the correlation of lipids and lipoproteins with cardiac function in patients with coronary heart disease (CHD).MethodsParameters of blood pressure, serum lipids and lipoproteins, clinical features, radionuclide ventriculographic and coronary angiographic findings were analyzed retrospectively in 584 CHD patients treated with standard treatment.ResultsThe left cardiac dysfunction of CHD patients was correlative positively with age, systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose, body mass index (BMI), smoking, total cholesterol(TC) and low density lipoprotein cholesterol(LDL-ch) significantly(P<0.001), not correlative with high density lipoprotein-cholesterol (HDL-ch). The left ventricular ejection fraction (LVEF) and left ventricular peak filling rate (LVPFR) were decreased along with the levels of TC and LDL-ch increased (P<0.05～0.01).ConclusionTC and LDL-ch are positively correlative with left cardiac dysfunction in CHD patients. In order to reduce cardiac damage of CHD associated with hyperlipoidemia, more attention should be paid to the amelioration of coronary arteriosclerosis and the reduction of serum lipids and lipoproteins.

OBJECTIVETo observe the changes in expression of microRNA-203 and P63 in human epidermal stem cells and KCs, and to investigate their effects and significance in the epidermal proliferation and differentiation.

METHODS(1) Five normal foreskin tissue specimens were collected from 5 patients by circumcision in Department of Urinary Surgery of the First Affiliated Hospital of Nanchang University from March to June in 2013. Then single cell suspension was obtained by separating epidermis with trypsin digestion method. The cells were divided into quick adherent cells and non-quick adherent cells by type IV collagen differential adherent method. The biological characteristics of cells were observed by inverted phase contrast microscope immediately after isolation and on post culture day (PCD) 3. The expression of CD29, keratin 19, keratin 1, and keratin 10 was identified by immunocytochemical staining. The expression of microRNA-203 and mRNA of P63 was determined by real-time fluorescent quantitative RT-PCR. The protein expression of P63 was determined by Western blotting. Data were processed with t test and Pearson correlation analysis.

RESULTS(1) Immediately after isolation, quick adherent cells were small, round, and dispersed uniformly. On PCD 3, the cells adhered firmly, and they grew in clones. Immediately after isolation, non-quick adherent cells appeared in different shapes and sizes, and dispersed unevenly. On PCD 3, the cells adhered precariously and did not show clonal growth. Quick adherent cells showed positive expression of CD29 and keratin 19, while non-quick adherent cells showed positive expression of keratin 1 and keratin 10. Quick adherent cells were identified as epidermal stem cells, and non-quick adherent cells were identified as KCs. (2)The expression level of microRNA-203 in epidermal stem cells (0.74 ± 0.20) was lower than that in KCs (3.66 ± 0.34, t =16.582, P <0.001). The mRNA expression level of P63 in epidermal stem cells (4. 16 ± 0.28) was higher than that in KCs (2.90 ± 0.39, t =5. 850, P =0.001). The protein expression level of P63 in epidermal stem cells (1.42 ± 0.05) was higher than that in KCs (0.73 ± 0.03, t =26.460, P <0. 001). (3) The expression level of microRNA-203 was in significantly negative correlation with the expression levels of mRNA and protein of P63 (with r values respectively - 0. 94 and -0.98 , P values below 0.05).

CONCLUSIONSThe expression levels of microRNA-203 and P63 in human epidermal stem cells and KCs were significantly different, which might be related to the different characteristics of proliferation and differentiation of the cells.
