OBJECTIVETo observe therapeutic effects of bird-pecking moxibustion in children of hand, foot and mouth disease, and to analyze the mechanism.

METHODSSeventy-five children of hand, foot and mouth disease were randomly divided into 3 groups, a combined moxibustion and medicine group (n = 22), a Chinese medicine group (n = 29), and a western medicine group (n = 24). The combined moxibustion and medicine group was treated with bird-pecking moxibustion combined with routine western medicine, the Chinese medicine group with oral administration of Chinese medicine and routine western medical therapy, and the western medicine group with routine western medicine. After treatment of 7 days, the therapeutic effects on skin rash, oral herpes, constipation or loose stool, dyspepsia and anorexia, etc. were comprehensively assessed, and their therapeutic effects were compared.

RESULTSThe total effective rate was 95.5% in the combined moxibustion and medicine group, 86.2% in the Chinese medicine group, and 83.3% in the western medicine group, the former being significantly better than those of the other two groups (both P < 0.05). The combined moxibustion and medicine group was significantly better than the other two groups in the relieving time of skin rash, oral herpes, constipation or loose stool, dyspepsia and anorexia, etc. (all P < 0.05)

CONCLUSIONThe combined moxibustion and medication can effectively improve symptoms of the digestive tract, shorten duration of disease, reduce pain in the patient with hand, foot and mouth disease.

OBJECTIVETo analysis comparatively the primary clinic outcomes between minimal extracorporeal circulation (MECC) and conventional extracorporeal circulation (cECC).

METHODSForty cases accepted coronary artery bypass grafting from August to October at 2006 were divided into MECC group and cECC group at random, 20 cases for each group. Record and analysis of the general information, clinic data perioperatively, and complications postoperatively for each group were performed.

RESULTSThere were no deference between groups in gender, anamnesis and preoperative cardiac function, while age (P < 0.05), standard EuroSCORE and logistic EuroSCORE were much more higher in MECC group than in cECC group (P < 0.01). Similarly, there were no deference in operative time, bypass time, ischemic time and graft number between two groups. Contrasted with cECC group, the values of cTNI were lower in MECC group at 2 h, 6 h and 12 h post-ECC (P < 0.01), oxygen index were higher post-operatively and there was a statistic deference at 12 h post-ECC (P < 0.05). The valves of ALT and TBIL in cECC group were higher abnormally at early post-ECC, and significant higher than in MECC group at 2 h, 6 h post-ECC of ALT (P < 0.05), and at termination, 2 h post-ECC of TBIL (P < 0.05). The values of activated partial thromboplastin time were almost at physiological status in MECC group, but were significantly prolonged in cECC group at early post-ECC, and were statistically longer than in MECC group at 2 h, 6 h, 12 h post-ECC (P < 0.05). The concentration of free hemoglobin in cECC group were higher than in MECC group peri-operative, and there was a statistic deference at 2 h post-ECC (P < 0.05). There were no deference between the two group in Cr, PLT and WBC.

CONCLUSIONSCompared with cECC, MECC carries more biocompatibility, more safe and credible. MECC system can alleviate the organ injury postoperatively and decrease the incidence of complications, especially in high-risk patients.

OBJECTIVETo analyze the gene mutation in two pedigrees of inherited coagulation factor VII (FVII) deficiency, and investigate the relationship between the genotype and phenotype.

METHODThe coagulation function and coagulation factors activity of probands were detected for phenotype diagnosis, all exons and junctions of FVII gene from the family members' genomic DNA were amplified using polymerase chain reaction (PCR), and detected the gene mutation by direct sequencing. Mutations were confirmed by reverse sequencing.

RESULTThe prothrombin time (PT) of proband 1 was 265.2 s, FVII:C was 22% and the PT of proband 2 was > 120 s, FVII:C was 1%. Homozygous 17844G→A mutation in No. 8 exon of FVII gene was identified in the proband 1 resulting in Gly343Ser, and heterozygosity for the same mutations were confirmed in his parents and a sister. The proband 2 was compound heterozygous, one mutation was the same as the proband 1 but was a heterozygosity that can also found in his mother and brother; the other heterozygosity mutation was located on No. 8 exon 18055G→A that resulted in Gln413Arg which was inherited from his father.

CONCLUSIONNo. 8 exon of FVII gene encodes catalytic domain. Mutation found in those domain could change the FVII catalytic domain spatial structure, affected FVII function and stability, and the sufferer of homozygote and compound heterozygous may have clinical bleeding tendency. Almost no clinical findings in simple heterozygotes, however, a few of heterozygotes could have a tendency of bleeding because of genetic polymorphism which would reduce the FVII:C.

OBJECTIVETo identify the relative factors of recent discovered atrial fibrillation (AF) following isolated coronary artery bypass grafting (CABG).

METHODSClassified the 649 cases undergoing isolated CABG from January 2005 to December 2006 to two groups according to whether AF appeared after operation. Collected the peri-operative data and operative strategy, then analyzed with single-factor analysis and Logistic regression.

RESULTSThe incidence of AF was 8.0% (52 cases), and 84.6% (44 cases) recovered sinus-rhythm leaving hospital. Age, standard European system for cardiac operative risk evaluation (EuroSCORE), ratio of high-operative-risk, left atrium diameter and ratio of left coronary artery dominance were higher in AF group than in non-AF group. Age, eject fraction, left atrium diameter, operative risk evaluation, left coronary artery dominance and anastomosis on right coronary artery were the relative factors of recent discovered AF following isolated CABG. But off-pump operation, prescription of adrenergic beta-antagonists pre-operatively and degree of coronary artery stenosis had no influence to AF.

CONCLUSIONSAF following CABG is a result of common influence by many factors. EuroSCORE might forecast partially the incidence of AF following CABG. Improve the myocardial protection and reduce the surgical damage during operative progress maybe the mostly approach to decrease the incidence of AF following CABG.

OBJECTIVETo analyze the clinical effect of minimal extracorporeal circulation (MECC) in blood conservation perioperatively coronary artery bypass graft (CABG).

METHODSThe data of 120 cases received simple CABG since August 2006 to October 2009 was analyzed retrospectively. All the patients were divided to three groups according to the mode of circulation support in-operation: MECC, conventional extracorporeal circulation (cECC) or off-pump, 40 cases in each group. Jostra MECC system with normal temperature was used in MECC group, and common membrane oxygenator with moderate hypo-temperature was used in cECC group. Collect the data of coagulation and the blood cytological examination perioperatively, the draining volume during the first 24 h after operation, and consumption of blood products perioperatively.

RESULTSStandard and logistic EuroSCORE were higher in MECC group than the others (P < 0.01). The operative time and the number of distal anastomosis of off-pump group were less than MECC and cECC groups (P < 0.05), while no difference between MECC group and cECC group. Intrinsic coagulation (activated partial thromboplastin time) were much more prolonged early postoperatively in cECC group, and higher than in MECC group and off-pump group at 2 h, 6 h and 12 h postoperatively (P < 0.05), but no difference in extrinsic coagulation (prothrombin time) among three group. Adjusted by hematocrit of the same sample, free hemoglobin level rose up during the ECC procedure and reached the maximum at the end of ECC in cECC group and MECC group, but the levels were more higher in cECC group than in MECC group (P < 0.05). The draining volume during the first 24 h after operation of cECC group was larger than MECC group and off-pump group (P < 0.05). Although the decreased platelet count perioperatively and more consumed of the blood products in cECC group, but no difference among the three groups.

CONCLUSIONMECC could reduce the ruin to blood cell and interfere to coagulation function during the conventional ECC procedure, decrease the postoperative draining volume and requirement of blood products.

OBJECTIVETo investigate the prevention and rescuing measures of postoperative fatal bleeding induced by carotid blowout in head and neck tumors.

METHODSSeven 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 pre- or 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 myocutaneous flaps.

RESULTSOf 7 patients with carotid blowout, 5 patients were successfully rescued 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.

CONCLUSIONSThe 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, self-expanding covered stent implantation may be more reliable for restoring the blood supply of head and neck region, with less complications. One-stage repair of carotid region with myocutaneous flap is of great importance to protect the carotid and to promote the wound healing.

Objective To analyze the clinical and imaging features of a family(3 patients)with familial hemangioblastoma,and their diagnosis and prognosis.Methods The detailed data about clinical and imaging features of all patients diagnosed as familial hemangioblastoma,admitted to our hospital from October 2004 to May 2010,were analyzed,and the lesions of other regions,besides the tumor lesion,were observed.Results No lesions of other regions were noted in these 3 patients.Cranial MRI showed that 2 had cystic and solid tumor and 1 had solid tumor;,total removal was performed on these patients under microscope; regular follow-up was given and no recurrence was noted.Conclusion Familiar hemangioblastoma is serious hereditary disease; and MRI is the most important detective method; microsurgical operation is the most important therapy.Early diagnosis and treatment should be given to the patients with familiar hemangioblastoma due to its high recunence rate,having difficulty in operation and its trend to combining with other lesions of the other parts.

The type I interferon and IFNAR play an important role in hepatitis B virus (HBV) infection and anti-HBV therapy. However, its mechanism of action is still poorly understood. To gain more insights into the role of type I interferon and type I interferon receptor (IFNAR) in HBV infection, we established an HBV persistent replication IFNAR knockout (IFNAR(-/-)) mouse model and preliminarily applied this model. At first, the progeny of IFNAR(-/-) mouse was reproduced. Then hydrodynamic injection with pAAV/HBV1.2 plasmid was conducted to establish the persistent HBV replication IFNAR(-/-) mouse model. At last, we applied this model to evaluate the effect of nucleoside analogues entecavir (ETV) on HBV replication. It was found that there was no difference in the serum HBsAg and HBeAg levels and HBcAg expression in the liver tissue between the ETV treated groups and normal saline (NS) treated group, but the serum HBV DNA levels were significantly suppressed 10, 25, 40 and 55 days after the ETV treatment [P=0.035, P=0.00, P=0.149 and P=0.084, IFNAR knockout (KO) control group vs. C57BL/6 ETV groups, respectively; P=0.081, P=0.001, P=0.243 and P=0.147, IFNAR KO control group vs. IFNAR KO ETV groups, respectively]. Interestingly, there was no difference in serum HBV DNA levels between the ETV treated IFNAR(-/-) and C57BL/6 mice. This result suggests that HBV suppression during ETV treatments doesn't depend on type I interferon and IFNAR. Collectively, persistent HBV replication IFNAR(-/-) mouse model that we established is a useful and convenient tool to detect the function of the type I interferon and IFNAR in HBV infection and anti-HBV treatments.

Long-term compliance with regular surveillance is important for the prevention and timely management of chronic hepatitis B (CHB). However, there are no researches focusing on the compliance of hepatitis B virus infected patients in regular surveillance so far. The purpose of our study was to investigate the outpatient compliance with long-term regular surveillance in China. Data of 3257 CHB outpatients was pooled and analyzed to assess the outpatient's compliance with the long-term regular surveillance plan. In all outpatients, the non-follow-up and the follow-up group accounted for 73.2% and 26.8%, respectively. Among the follow-up outpatient's, only 48.9% received ongoing-follow-up and 51.1% were finally lost to follow-up; the median length of visiting duration was 25 months; and the predictive 1-, 2-, 3-, 4- and 5-year ongoing follow-up rate was 72.7%, 52.5%, 42.4%, 33.8%, and 26.3%, respectively. In conclusion, our survey proved that the regular long-term surveillance on Chinese chronic HBV carrier is difficult to be fully implemented. A large proportion of outpatients do not receive routine follow-up and are at risk of treatment delay due to various social reasons.
