Objective To investigate the curative effect of YU Yun pulse-feeling-based acupuncture therapy for the treatment of middle-late liver cancer. Methods A total of 60 middle-late liver cancer patients were divided into control group and treatment group by stratified randomization method,30 cases in each group. The control group was given integrated Chinese and western medicine therapy according to the clinical pathway, including anti-cancer treatment such as vascular interrention,molecular targeted therapy,chemotherapy,radio therapy, and focal ablation therapy,as well as chinese medicine treatment based on disease differentiation and syndrome differentiation. And the treatment group was given YU Yun pulse-feeling-based acupuncture therapy on the basis of treatment for the control group. The two groups received 12-week treatment, and then their curative effects were compared. Results The treatment group had better effect on increasing the survival rate, prolonging survival time, improving the scores of clinical symptoms, stabilizing tumor size, and increasing the scores of Karnofsky Performance Status (KPS)than the control group,the difference being significant (P < 0.05 or P <0.01). Conclusion YU Yun pulse-feeling-based acupuncture therapy exerts certain curative effect for the treatment of middle-late liver cancer.

Objective To investigate the prevention and rescuing measures of postoperative fatal bleeding induced by carotid blowout in head and neck tumors. Methods Seven cases with postoperative carotid bleeding treated from October 2003 to August 2009 were reviewed retrospectively. Of the patients, 6 were with common carotid blowout and one with internal carotid artery blowout. All patients underwent preor post-operative radiotherapy for primary head and neck tumours and 3 patients had neck defect repair with deltopectoral skin flap, frontal flap or free radial arm flap respectively. After carotid blowout bleeding, the patients were treated in time with X ray transcatheter intervention including transcatheter arterial embolization (TAE) and self-expanding covered stent implantation, followed by repairing the carotid region with appropriate myocutenous flaps. Results Of 7 patients with carotid blowout, 5 patients were successfully rescured with X ray transcatheter intervention, of them 2 with self-expanding covered stent implantation and 2 with TAE respectively, and other 2 patients died due to rapid bleeding. Of the successfully rescued patients, 2 patients were with the repair of carotid area by pectoralis major myocutaneous flap, one by submental flap and one by local flap, but another one not with flap repair. Follow-up showed the 3 patients rescued with self-expanding covered stent implantation were survival for 6,12,and 20 months, respectively, and the 2 patients rescued with TAE died of repeated carotid blowout in 2 and 13 months later, respectively. Conclusions The planned and timely X ray transcatheter intervention is an effective method to treat carotid blowout bleeding in the patients underwent head and neck tumour surgeries. Compared with TAE, selfexpanding covered stent implantation may be more reliable for restoring the blood supply of head and neck region, with less complications. One-stage repair of caratid region with myocutenous flap is of great importance to protect the carotid and to promote the wound healing.

Objective To explore the clinical features of sleep disorder in patients with stroke and its related factors. Methods Two hundred and four patients with stroke, admitted to our hospital from January 2005 to June 2010, were chosen; Pittsburgh Sleep Quality Index (PSQI) was employed to determine whether these patients had sleep disorder; the prevalences of sleep disorder in patients with different ages, genders and lesions of stroke were compared. Symptom Checklist-90 (SCL-90)questionnaire was used to compare the physical and mental conditions of patients with or without sleep disorder; Hamilton Depression Rating Scales (HAMD), Barthel index, and National Institutes of Health Stroke Scale (NIHSS) were employed to compare the differences of depression, viability and neurologic impairment in patients with or without sleep disorder. Results The prevalence of sleep disorder was 46.6% (95/204), and it was higher in female group (53.8% vs 38.8%; x2=3.851, P=0.033). Patients aged ≥70 years had the highest rate of sleep disorder (57.6%), followed by patients aged ＜50 years (41.5%),and then patients aged between 50 and 69 years showed the lowest rate (32.9%). The sites of stroke located in the subcortex, cortex, and cerebellum enjoyed their prevalences of 64.2%, 27.4% and 4.5%,respectively. The incidence of sleep disorder in patients with stroke located in the left hemisphere was obviously higher than that in the right hemisphere (x2=7.688, P=0.008). The results of 9 indexes of SCL-90, scores of HAMD and NIHSS in patients with sleep disorder were significantly higher than those in patients without sleep disorder, while the Barthel index was in the opposite position with obvious differences (P＜0.05). Conclusion High prevalence of sleep disorder in patients with stroke is noted,which is related to gender, age of the patients and the sites of stroke, and may lead to depression, anxiety,neurological functional deficit and decrease of life quality. And we should pay more attention to nursing care during all the treatment.

OBJECTIVEThe purpose of this study was to describe survival status and risk factors of mortality on inpatients with ischemic stroke.

METHODS617 patients with continuous ischemic stroke cases were collected from January 2002 to June 2005 retrospectively in the Department of Neurology, Xijing Hospital, Fourth Military Medical University. In order to perceive relevant information on survival and the cause of death. All patients were followed through phone calls or mailing. The follow-up program was completed in January 2006. Kaplan-Meier methods were used for survival description. Monovariant and multivariant Cox's proportional hazard regression model were used to analyze prognostic factors on mortality.

RESULTSThe longest time in the follow-up program was 47 months with 59 dropped-out cases, making the dropout rate as 9.5%. Of these patients, 80 cases died during the period of study(60 for ischemic stroke,3 for cerebral hemorrhage, 10 for cardiac disease, 7 for other cause). The median survival time was 42. 16 months. The survival rates of one-year, two-year and three-year period were 91.9%, 89.4% and 85.3%, respectively. Monovariant and multivariant Cox's proportional hazard regression model showed that the risk factors associated with mortality were old age (RR = 1.043, 95% CI: 1.013-1.074), lower Glasgow scores (RR = 0.855, 95% CI: 0.742-0.985) ,poor conscious levels(RR = 4.085, 95% CI: 2.128-7.844) and having complication (RR = 1.765, 95% CI: 1.108-2.812).

CONCLUSIONThe results of this study suggested that the risk factors were old age, lower Glasgow scores, poor conscious levels and having complication on mortality of ischemic stroke.

OBJECTIVETo explore the effects of percutaneous transhepatic radiofrequency ablation (PRFA) combined with tumor edge of percutaneous absolute ethanol injection (PEI) on liver cancer adjacent to major blood vessels.

METHODSSeventy five patients with liver cancer adjacent to major blood vessels were randomly divided into two groups: PRFA+PEI therapy group (38 cases) and PRFA control group (37 cases). Tumor necrosis rate, AFP levels, local recurrence rate, median for survival time and cum survival were used as the evaluation index to evaluate the efficacies of the two methods.

RESULTSTumor necrosis rates of the therapy group and the control group were 84.2% and 54.1% (P < 0.01), respectively; AFP levels of therapy group and control group at 1, 3, 6 and 12 months after treatment were (105.0 ± 35.5) μg/L, (28.4 ± 4.3) μg/L, (58.6 ± 6.7) μg/L, (89.5 ± 12.5) μg/L and (137.2 ± 34.6) μg/L, (84.2 ± 18.4) μg/L, (106.6 ± 20.3) μg/L, (173.7 ± 32.0) μg/L, respectively. The rates of therapy group was significantly lower than of control group. Local recurrence rates of the therapy group and control group were 2.6%, 7.9%, 13.2% and 31.6% vs 10.8%, 21.6% , 40.5% and 62.1% (P < 0.05) at 3, 6, 12 and 24 months after treatment, respectively. Median for survival time of the therapy group and control group were 28.0 ± 2.8 months and 19.0 ± 3.6 months, respectively. Cum survival of the therapy group and control group were 84.2%, 78.9%, 60.5% and 31.6% vs 78.4%, 67.6%, 37.8% and 8.1% (P < 0.05) at 6, 12, 24 and 36 months after treatment, respectively.

CONCLUSIONPEI as a supplementary treatment of PRFA can effectively improve the treatment of liver cancer adjacent to major blood vessels and significantly reduce the local recurrence rate and improve long-term survival rates.

BACKGROUNDIt is unclear whether a history of paroxysmal atrial fibrillation (PAF) would impact the effect of catheter ablation on persistent atrial fibrillation (AF). This study aimed to compare the effect of catheter ablation on persistent AF with and without a history of PAF.

METHODSOne hundred and eighty-three patients underwent catheter ablation of persistent AF lasting for > 1 month and were reviewed. Patients were divided into two groups according to whether they had a history of PAF or not. Group I consisted of persistent AF patients with a history of PAF, and group II consisted of persistent AF patients without such a history. All patients received catheter ablation focused on pulmonary vein isolation and were observed for arrhythmia recurrences, which were defined as documented episodes of AF or atrial tachycardia after a blanking period of 3 months.

RESULTSOne hundred and three patients (60.9%) in group I and sixty-six patients (39.1%) in group II were successfully followed and included in analysis. There were no significant differences in clinical and echocardiographic characteristics between both groups except for a younger age and more male patients in group II. After (15.5 ± 10.7) months of follow-up, 59 (57.3%) patients in group I and 49 (74.2%) patients in group II maintained sinus rhythm free of anti-arrhythmia drugs (P = 0.025). Multivariate analyses found left atrial anteroposterior diameter (P = 0.006) and persistent AF with a history of PAF (OR 1.792, 95%CI 1.019 - 3.152; P = 0.043) as the only independent statistical predictors of arrhythmia recurrences.

CONCLUSIONThe arrhythmia recurrence rate of catheter ablation based on pulmonary vein isolation in persistent AF with a history of PAF was higher than those without a history of PAF.

The present report demonstrates two cases of transient inferior ST-segment elevation accompanied by profound hypotension and bradycardia immediately after transseptal puncture for catheter ablation of atrial fibrillation. This rare complication of transseptal puncture was resolved quickly within several minutes. The most likely mechanism of this phenomenon is coronary vasospasm, although coronary embolism can not be ruled out completely. This complication is characterized as follows: (1) The right coronary artery might be the most likely involved vessel and therefore myocardial ischemia usually occurs in the inferior wall of left ventricular; (2) Reflex hypotension and bradycardia by the Bezold-Jarisch reflex secondary to inferior ischemia often occur at the same time. Though it appears to be a transient and completely reversible phenomenon, there are still potential life-threatening risks because of myocardial ischemia and profound haemodynamic instability. Clinical cardiologists should be aware of this rare complication and properly deal with it.

Objective To understand the status of HIV infection and sexual behaviors with men and women among men who have sex with men and women (MSMW) and documented for HIV epidemic among men who have sex with men to the general population.Methods 300 participants were recruited by using "snowballing" sampling in Chengdu and Guangzhou,respectively.Participants completed the questionnaire and HIV test.The questionnaire included social demographic characteristics,number of male sexual partners,sexual behaviors and condom use in the past 6 months.Relations with female sexual partners,vaginal intercourse and condom use in the past 12 months were also studied.Results Of the 600 oarticioants,the overall prevalence of HIV infectionwas 26.2％ and the detection rate of HIV-positives in this survey was 8.5％.In the past 6 months 28.0％ of the participants had 5 or more male sexual partners and the percentage of MSMW who had used condoms consistently during anal sex intercourse with men,was 44.2％.Of the participants,52.3％ had used condoms in the last three anal sex events and 63.0％ in the last event.In the past 12 months,86.0％ of the participants who had vaginal sex with female partners and the proportions of MSMW who had wife,girlfriend,lover,female casual partner and female commercial partner were 65.0％,27.2％,1.5％,12.7％,4.5％,respectively.About a third of the MSMW had always used condoms when having vaginal sex in the past 12 month.In the last three vaginal sex events,the proportion of participants who had never used condoms was 36.5％.In the past 6 months,55.7％ of the MSMWs had used condoms consistently during anal sex with men in Chengdu,which was higher than those MSMW in Guangzhou (32.7％).In the past 12 months,the proportion of MSMW who had used condoms consistently during vaginal sex was 38.3％,which was higher than MSMW of Guangzhou (25.3％).Among those HIV-positive MSMWs,91.1％ had anal sex with men in the past 6 months and 49.7％ HIV-positive MSMW had used condoms consistently during anal sex with men.The number of HIV-positive MSMW who had used condoms in the last or last three anal sex events with men,accounted for 60.5％ and 69.4％,respectively.In the past 12 months,82.8％ of the HIV-positive participants had vaginal sex with women.Of the HIV-positive participants,42.0％ used condoms consistently and the percentage of HIV-positive MSMWs who used condom during last three vaginal sexes was 47.8％.In the past 6 months,the percentage (4.3％) of MSMW who were HIV-positive prior to the survey and never used condoms during anal sex with men was lower than the percentage (22.0％) of MSMW who were HIV-positive found in this survey.In the past 12 months 12.9％ of the MSMW who were HIV positive prior to the survey never used condoms when having vaginal sex event,which was lower than MSMW (46.3％) who were HIV positive in this survey.Conclusion The prevalence of HIV infection had reached a quite high level and with high rates of unprotected anal sex with men and vaginal sex with women among MSMWs,indicating that the inherent bridging aspect of MSMW might accelerate the spreading of HIV infection to the general population.

This report aims to investigate the dynamical changes of HBcAg18-27 epitope specific cytotoxic T lymphocytes(CTL), alanine aminotransferase (ALT), HBV DNA and HBsAg in peripheral blood of acute hepatitis B patients, and to explore the roles of HBcAg18-27-specific CTLs in virus clearance and liver injury. Acute hepatitis B (AHB) and chronic hepatitis B (CHB) patients were divided into two groups according to results of HLA-A0201. Patients with positive HLA-A0201 were classified into HBcAg-specific CTL group and those with negative HLA-A0201 were referred as control group. The specific CTLs were stained with HLA-A0201 limited HBcAg18-27 epitope MHC-Pentamer and the frequencies of CTLs, T, B, NK and NKT cells were detected by flow cytometry (FCM). The serum ALT, HBV DNA and HBsAg were examined using speed analysis, quantitative PCR and abbott chemiluminescent technology. The frequencies of HBcAg18-27-specific CTLs in AHB patients were higher in the early three weeks as compared to the late three weeks. The apex time of HBV-specific CTL frequencies lagged behind those of HBV DNA, HBsAg and ALT. The loss of HBsAg in patients with high frequencies of HBV-specific CTL was earlier than that in patients with low frequencies (t = 2.018, P value is less than 0.05). In the second week the peak frequencies of CD3+CD8+ cells overlapped with that of HBcAg18-27-specific CTLs and with a positive correlation between (r = 0.420, P value is less than 0.05). During the early stages of AHB, the frequencies of NK and NKT cells were found significantly lower than that of control group and CHB group and the levels were back to normal after recovery. Moreover, a negative correlation existed between the frequencies of NK cells and the dynamic changes of HBcAg18-27-specific CTLs (r = -0.435, P value is less than 0.01) in AHB group. The frequencies of HBcAg18-27-specific CTLs were significantly higher as compared to CHB group in the first three weeks (z = -3.258, -4.04, and -3.259, P value is less than 0.01). The early loss of HBsAg was closely related to the high frequencies of HBcAg18-27 specific CTLs in AHB patients. HBcAg-specific CTL frequencies in peripheral blood could be used to predict clinical outcome after HBV infection. The frequencies of CD8+ T cells can reflect the changes of frequencies of HBcAg-specific CTL during acute HBV infection.
