OBJECTIVETo determine the difference of post-operative mortality between ORIF (open reduction internal fixation) and hip replacement for the treatment of intertrochanteric fracture in elderly by using survival analysis.

METHODSThe clinical data of 110 patients above 60 years old who underwent surgical treatment (ORIF or hip replacement) for the intertrochanteric fracture between April 2003 and May 2013 were retrospectively analyzed. Among the patients, 83 cases were treated with ORIF (ORIF group), there were 32 males and 51 females, aged from 61.44 to 98.75 years old with an average of (78.52 ± 7.98) years old; and 27 cases were treated with hip replacement (arthroplasty group), there were 8 males and 19 females, aged from 71.82 to 96.54 years old with an average of (79.99 ± 6.11) years old. A survival analysis was performed on the clinical data by using SPSS 110 software. The survival rate of 1-year,2-year, 5-year and the mean survival time for the total patients, the mortality rate of 1-year, 2-year in each group, the survival rate of 1-year, 2-year and mean survival time and survival curve in each group were included.

RESULTSAll wounds achieved primary healing and no deaths were found in stay hospital. All patients were followed up from 1 to 125 months with an average of (46.93 ± 29.53) months. Among all 110 cases, 31 were dead and 79 survived. The survival rate of 1-year, 2-year and 5-year was (90.7 ± 2.8)%, (82.5 ± 3.9)% and (57.6 ± 6.5)%, respectively,while the ensemble mean survival time was (84.137 ± 5.902) months. The mortality rate of 1-year, 2-year in ORIF group was 7.2% and 12.0%, respectively; and in arthroplasty group, there was 14.8% and 25.9%, respectively. There was no significant difference in mortality rate of 1-year and 2-year between two groups. According to the survival analysis of the ORIF group, the survival rate of 1-year, 2-year was (92.6 ± 2.9)%, and (85.8 ± 4.3)%, respectively, and the mean survival time was (87.508 ± 6.063) months. In arthroplasty group, the survival rate of 1-year, 2-year was (85.2 ± 6.8)% and (73.9 ± 8.5)%,and the mean survival time was (67.294 ± 11.180) months. There was significant difference in mean survival time between two groups (P < 0.05).

CONCLUSIONORIF can achieve a better postoperative survival compare with hip replacement in treating intertrochanteric fracture in elderly.

This study was aimed to retrospectively analyze and compare the clinical curative efficacy of patients with hematologic malignancies after G-CSF-mobilized sibling HLA-matched (sm) peripheral blood hematopoietic stem cell transplantation (sm-allo-PBHSCT) and sm-allo-PBHSCT combined with bone marrow transplantation (BMT). 100 patients received sm-allo-HSCT in a single center from October 2001 to October to 2010, included 38 patients received sm-allo-PBHSCT and 62 patients received sm-allo-PBHSCT combined with BMT. The myeloablative or reduced intensity conditioning regimens were chosen according to the condition of patients. All patients received standard cyclosporine (CsA) and mycophenolate mofetil (MMF) as prophylaxis for GVHD. The results showed that the rapid hematopoietic reconstitution was observed in all patients. The median time of ANC ≥ 0.5 × 10(9)/L in both groups were 12 days, the median time of platelet count ≥ 20 × 10(9)/L was 15 days in sm-allo-PBHSCT group and 16 days in sm-allo-PBHSCT + BMT group. The incidence of acute GVHD, acute GVHD of III-IV grade and chronic GVHD in sm-allo-PBHSCT and sm-allo-PBHSCT + BMT groups were 37.1% and 34.2%, 7.89% and 8.06%, 36.11% and 41.38% respectively, there were no statistical differences. The relapse rates were similar in two groups (sm-allo-PBHSCT 13.16% vs sm-allo-PBHSCT + BMT 12.9%). The 3-year disease-free survivals in sm-allo-PBHSC and sm-allo-PBHSCT + BMT groups were 57.1 ± 8.7% and 61.3 ± 6.4% respectively (p = 0.852). The 2-year overall survival of high-risk patients was 41.4 ± 12.8% in sm-allo-PBHSCT group, while 60.9 ± 9.6% in sm-allo-PBHSCT + BMT group (p = 0.071). It is concluded that the rhG-CSF mobilized sibling matched allo-PBHSCT + BMT is superior to the rhG-CSF mobilized sibling matched allo-PBHSCT in increasing the overall survival of high-risk hematologic malignancies.

BACKGROUND:As the regulators of cytokines, suppressors of cytokine signaling (SOCS) play an important role in the inflammation reaction. Some studies found that SOCS-1 and SOCS-3 were involved in the pathogenesis of some inflammatory diseases such as rheumatoid arthritis, inflammatory bowel disease. But the expressions of SOCS in coronary heart disease have not yet been reported. This study aimed to investigate the expression and clinical significance of SOCS-1 and SOCS-3 in the myocardium of patients with sudden cardiac death (SCD).METHODS:Myocardial autopsy specimens were collected from 24 patients at the Forensic Medicine Department of Sun Yat-Sen University, Guangzhou, China between 2005 and 2006. Of them, 9 patients had autopsy findings consistent with coronary atherosclerosis (non-myocardial infarction) leading to SCD (non-MI group), 7 died of acute myocardial infaction (MI group), and 8 died from traffic accidents and trauma (control group). The expressions of SOCS-1 mRNA and SOCS-3 mRNA in the myocardium of the non-MI, MI and control groups were detected using RT-PCR. The levels of SOCS-1 and SOCS-3 proteins were detected using immunohistochemistry. Statistical analyses were performed using SPSS version 13.0 software and the data were analyzed by ANOVA.RESULTS:The expressions of SOCS-1 mRNA and SOCS-3 mRNA in the non-MI and MI groups were significantly higher than those in the control group[(0.788±0.101), (0.741±0.111) vs. (0.436±0.044), (P<0.01); (0.841±0.092), (0.776±0.070) vs. (0.454±0.076), (P<0.01)] respectively. The antibody-positive cells of SOCS-1 protein in the myocardium of the non-MI and MI groups were significantly higher than those in the myocardium of the control group[(320.00±48.48), (347.14±70.88) vs. (42.50±10.35), (P<0.01)] respectively. The antibody-positive cells of SOCS-3 protein in the myocardium of the non-MI and MI groups were significantly higher than those in the myocardium of the control group[(381.11±59.25) vs. (40.00±10.69), (P<0.01)] and[(332.86±111.91) vs. (40.00±10.69), (P=0.001)].CONCLUSION:The expressions of SOCS-1 and SOCS-3 in the myocardium of patients with SCD from coronary heart disease are significantly increased and contribute to the pathogenesis of SCD.

OBJECTIVETo explore the clinical effect of low dose pituitrin in children with septic shock.

METHODSA total of 48 pediatric cases with septic shock, in whom 6 hours, conventional treatment could not reverse shock from January 2008 to December 2010, were selected for this study. The patients were divided into two groups randomly (completely random design) (control group 24, remedial group 24). The conventional treatment included antibiotics/fluid resuscitation/correcting acid-base imbalance, glucocorticoid, organ (heart/lung) support, dopamine 1 - 15 µg/(kg·min) and norepinephrine 0.5 - 2 µg/(kg·min) pumped in continuously in the control group. In initial 6 hours the same treatment was given to the remedial group, while low dose pituitrin (0.01 - 0.03 U/min) was pumped additionally during the rest of time. The therapeutic effect on correcting shock was evaluated in both groups.

RESULTSThe total effective rate was 76.2% in the remedial group and 40.0% in the control group; the mortality was 33.3% and 60% respectively. The difference between both groups was significant (P = 0.025).

CONCLUSIONLow dose pituitrin could improve the clinical effect significantly in children with septic shock in whom 6 hours conventional treatment failed to correct shock, shorten the total periods of treatment, and decrease mortality.

OBJECTIVETo compare the inhibitory effects of cytokine-induced killer (CIK) cells alone, chemotherapeutic drug alone, and CIK cells combined with chemotherapeutic drug on the growth of hepatocellular carcinoma (HCC) cells transplanted in nude mice.

METHODSPeripheral blood mononuclear cells (PBMC) collected from five healthy donors by blood cell separator were incubated in vitro to induce CIK cells in the presence of interferon-gamma (IFN-gamma), IL-2 and anti-CD3 monoclonal antibody (mAb). The phenotype of CIK cells was characterized by flow cytometric analysis. BEL-7402 HCC cells were inoculated subcutaneously to nude mice. On day 5, at the inoculation site were injected normal saline (group 1), CIK cells (3 x 10(7) and 6 x 10(7), group 2 and 3), mitomycin-C (MMC 80 microg in 0.2 ml, group 4), and CIK cells combined with MMC (group 5), respectively.

RESULTSThe percentage of CD3(+), CD3(+)CD8(+), CD3(+)CD56(+), CD25(+) cells increased from 64.0%, 28.0%, 7.8%, and 9.1% to 94.7%, 67.7%, 61.3%, and 84.0% respectively after cytokine induction. The percentage of CD3(+) and CD3(+)CD8(+) cells remained at high levels during incubation period, but that of CD25(+) and CD3(+)CD56(+) cells peaked respectively on day 7 and 13 and then declined. During the 90-day observation, the tumor formation rates were 100%, 70.0%, 80.0%, 70.0% and 66.7%; and the mouse survival rates were 10.0%, 60.0%, 40.0%, 50.0% and 75.0%, respectively from group 1 to group 5. Compared to the other groups, in the combined therapy group of mice, not only the tumor grew slowly and but also showed more marked tissue necrosis.

CONCLUSIONThe growth inhibitory effect on human HCC transplanted in nude mice of combined CIK cells and MMC treatment is more potent than that of CIK cells or MMC alone.

OBJECTIVETo investigate the effect of ecdysterone (EDS) on the proliferation of human bone marrow mesenchymal stem cells (hMSCs) in vitro.

METHODShMSCs were isolated from human bone marrow cell suspension by density gradient centrifugation. The expression of integrins CD44, CD105, CD34 and CD29 were examined by immunocytochemical method. EDS at 10, 25, 50 or 100 microg/ml were added in hMSC culture system, using the routine culture medium for hMSCs as control. The cell viability were analyzed by MTT assay and the cell cycle changes were examined by flow cytometry.

RESULTSThe optical density (OD) differed significant between the EDS treatment groups and the control group (P<0.01), and 25 microg/ml EDS group showed the highest OD value (P<0.01) without significant differences among 10, 50 and 100 microg/ml EDS groups (P>0.05). Flow cytometry showed that treatment of the cells with 25 microg/ml EDS significantly increased the cell percentages in S and G(2)M phases and the proliferation index (PI) of the cells as compared with the control group.

CONCLUSIONWithin a given concentration range, EDS can promote the proliferation of hMSCs in vitro, and this effect can be the most obvious at the concentration of 25 microg/ml. The effect of EDS in promoting the proliferation of hMSCs does not positively correlate to EDS concentration administered.

OBJECTIVETo evaluate the safety and effectiveness of endourological techniques in the treatment of benign prostate hyperplasia (BPH) in aged high-risk patients.

METHODSWe used endourological techniques in the treatment of 283 BPH patients aged over 70 years and complicated with hydronephrosis, renal failure, heart failure, cerebral infarction, respiratory dysfunction, anemia, diabetes, bladder tumor, or prostate weight over 80 g, TURP (transurethral resection of the prostate) for 112 cases and PKRP (transurethral plasmakinetic resection of the prostate) for the other 171. All the patients were followed up for 1-30 months.

RESULTSIn the TURP group, the scores on IPSS and QOL were decreased from 27.5 +/- 2.8, 5.5 +/- 1.0 to 5.8 +/- 1.2, 1.0 +/- 0.5, and the residual urine volume (RUV) from (75.0 +/- 20.0) ml to (8.0 +/- 3.0) ml, but the maximal flow rate (Qmax) increased from (6.5 +/- 2.0) ml/s to (18.5 +/- 1.5) ml/s (P < 0.05), while in the PKRP group, the scores on IPSS and QOL were decreased from 28.2 +/- 2.2, 5.5 +/- 1.0 to 5.4 +/- 1.6, 1.0 +/- 0.5, and RUV from (80.0 +/- 20.0) ml to (7.0 +/- 3.0) ml, and Qmax increased from (6.8 +/- 2.1) ml/s to (20.0 +/- 1.5) ml/s (P < 0.05). There were no statistically significant differences in IPSS, QOL, Qmax and RUV after treatment between the two groups (P > 0.05), but significantly less complications were found in the PKRP than in the TURP group (P < 0.05).

CONCLUSIONEndourological treatment, especially PKRP, with comprehensive perioperative preparations, unerring operative skills, well-controlled operation time, and intensive postoperative monitoring and nursing, has the advantages of high safety, less bleeding, fewer complications and definite effectiveness for aged high-risk BPH patients.

OBJECTIVETo observe the effect of acupuncture on cortical functional areas of the patient with ischemic stroke activated by the index finger motion.

METHODSThe cortical magnetic resonance imaging (fMRI) were carried out in 15 cases of ischemic stroke during the index finger motion at acupuncture or non-acupuncture. The distribution of the cortical functional areas activated and the size of the activated region and the intension of signals were measured.

RESULTSThe finger motion with no acupuncture could activate the contralateral primary somatomotor area (M1), contralateral premotor area (PMA) and contralateral first somatosensory area (S1). The finger motion with acupuncture could activate the same areas and also activate ipsilateral M1, focus area contralateral superior parietal lobule, contralateral superior temporal gyrus, and contralateral insular lobe, etc.. Both the area of the activated region and the minimum signal in the finger motion with acupuncture were statistically significantly larger than those in finger motion with no acupuncture.

CONCLUSIONRehabilitation of motor functions of the patient with ischemic stroke by acupuncture is related with improvement of blood circulation functional area in the cortex.

OBJECTIVETo observe the therapeutic effect of autologous cytokine-induced killer cells (CIK) on HBV DNA positive patients with liver cirrhosis.

METHODSHBV DNA positive 33 patients with cirrhosis were treated with CIK. Before and after cultured in vitro and post-treatment, CD3+, CD3+CD4+, CD3+CD8+, CD3+CD56+ cells, mDC and pDC were detected by flow cytometry. The indexes of virus and liver function were compared between pre- and post-treatment.

RESULTSCD3+, CD3+CD8+ cells and CD3+CD56+ cells were higher after cultured in vitro and after transfused back than those before culture (91.5 +/- 10.3, 74.4 +/- 9.9 vs. 67.9 +/- 12.8; 60.9 +/- 15.5, 37.3 +/- 15.1 vs. 27.9 +/- 10.9; 18.4 +/- 11.7, 14.5 +/- 7.5 vs. 10.6 +/- 7.1). The percentages of mDC and pDC also increased after-treatment vs. pre-treatment (0.54 +/- 0.18 vs. 0.70 +/- 0.29; 0.26 +/- 0.13 vs. 0.41 +/- 0.25). HBV DNA became undetectable in 12 patients and decrease exceeded 100 times in 4 patients after treatment. HBeAg became undetectable in 10 of 14 patients who were HBeAg positive pretreatment patients, among them 2 patients had HBeAb sero conversion. The liver function was improved after treatment. All patients tolerated the treatment.

CONCLUSIONCIK treatment can increase immune effector cells and has some antiviral effect and is safe.
