Objective To prospectively evaluate the efficacy and safety of Computed Tomography (CT)-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity prior to thoracoscopic resection.And to investigate the indication for CT-guided microcoil localization for small solid pulmonary nodules and ground-glass opacity.Methods From December 2012 to February 2014,85 enrolled patients with pulmonary solid nodules and ground-glass opacity underwent CT guided microcoil localization prior to video assisted thoracoscopic surgery.The procedures of localization were performed by trailing method or routine method under CT guided percutaneous pneumocentesis.For Trailing method,the microcoil was placed with the distal part coiled adjacent to the lesion and the proximal end coiled beyond the parietal pleura.By routine method,the entire microcoil was injected adjacent to the lesion.Results CT-guided microcoil placements were successful in all ninety-one lesions,including 15 solid nodules,15 mixed ground glass opacity,and 61 pure ground glass opacity,with an average diameter of 8.75mm(5-26 mm).The Complication rate of the localization procedure was 23.5％ (20/91),with 13 cases of asymptomatic pneumothorax,and 7 cases of pulmonary hematoma.None patient required surgical intervention,nor severe Complication occurred.All patients underwent video assisted thorascopic surgery on the same day or the next few days after microcoil localization.VATS removal of the pulmonary lesions was successful in all patients.However,two of 91 microcoils were found displaced during VATS resection.The success rate of microcoil marking VATS resection for pulmonary small solid nodules and ground-glass opacity was 97.8％.Microcoil marking was required for 84.6 percent of all the resected lesions.Conclusion Preoperatively CT-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity is a feasible safe and effective marking technique for video assisted thoracoscopic resection.The indication for microcoil localization in our study meet the requirement of VATS resection.

OBJECTIVETo investigate the migration of fluorescent dye PKH26-labeled BM-MSC in the Alzheimer's model rats.

METHODSNormal human bone marrow extracted for isolation of BM-MSC was cultured in vitro. The 5th passaged BM-MSC was labeled with PKH26, and observed under a fluorescence microscope for PKH26 labeling efficiency, and using flow cytometry BM-MSC surface markers was checked. The PKH26 labeled BM-MSC injected into the tail vein of the normal control group and AD animal model group, 14 days after finding the PKH26-labeled BM-MSC cells in the rat hippocampus using fluorescence microscopy. Using the Morris water maze experiment comparison of AD model and BM-MSC transplantation group of spatial learning and memory ability.

RESULTSTFlow cytometry showed BM-MSC surface markers CD73 and CD105 were positive. In vitro, PKH26-labeled rate of BM-MSC was 100 %. The Morris water maze experiment comparison of BM-MSC transplantation group and AD group of animals, BM-MSC transplantation group at 13, 14 days of spatial learning and memory ability than AD animal group had significantly improved. 14 days after BM-MSCs in rat hippocampus could be found which were PKH26-positive, consistent with DAPI staining. PKH26-positive cells in animal models of AD were significantly more than those in the normal control group.

CONCLUSIONBM-MSC in AD rats not only migrates through the blood-brain barrier, but also mainly survives in the hippocampus of AD rats, and it can improve AD rat model of learning disabilities.

ObjectiveTo observe the effect of Huanglian Wendan decoction and Danshen decoction combined with Wester medicineon stable coronary heart disease.Methods60 patients with angina or myocardial infarction were randomly divided into the control group and treatment group with 30 cases in each group. The patients of the control group were treated with routine medicine and those of the treatment group were added with traditional Chinese medicine (TCM) Huanglian Wendan decoction combined with Danshen decoction. The changes of angina, symptoms and signs of TCM, electrocardiogram (ECG), low density lipoprotein cholesterol (LDL-C) and high sensitive C-reactive protein (HS-CRP) of all patients were observed before and after treatment.ResultsAfter treatment, the frequency and duration of angina, dose of notroglycerine of patients in two groups were significantly different from those before treatment (P<0.01 ), but there was no significant difference between two groups (P>0.05). The symptoms such as chest discomfort and palpitation of patients of two groups improved after treatment (P<0.05～0.01), but the treatment group improved more obviously than the control group (P<0.05). The total effective rate showed by ECG were 53.3% in the control group and 73.3 % in the treatment group, there was no significant difference between two groups. HS-CRP and LDL-C of all patients decreased after treatment (P<0.01), but the treatment group was lower than the control group (P<0.05).Conclusion Huanglian Wendan decoction combined with Danshen decoction can relief clinical symptoms of stable coronary heart disease, which may be related with lipid decrease and inflammation reduction.

To assess the clinical effect and safety of Chinese traditional medicine injection combined with radiotherapy for esophageal cancer. The relative randomized controlled trials (RCTs) of Chinese medical injections (CMI) combined with radiotherapy as well as simple radiotherapy for esophageal cancer were searched from PubMed, Cochrane Library, EMBASE, Chinese Biomedical Literature Database(CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and VIP Database as at September 2014. Two researchers completed the data extraction and quality evaluation independently. The data were analyzed by GeMTC 0.14.3 and Stata 12. 0 software. Finally, 43 RCTs involving 3 289 patients were finally included. The star network was constructed by different comparison groups. The results of network meta-analysis showed that the seven CMIs combined with radiotherapy was superior to simple radiotherapy in the treatment of esophageal cancer in efficacy, quality of life, and reduction in the incidence of nausea and leucopenia, but with no significant difference among the seven CMIs. Probability ranking result showed a great possibility for Shenqi Fuzheng and astragalus polysaccharide injections in improving the overall response rate and quality of life, which were followed by cinobufagin and kangai injections. However, only one study was included for Shenqi Fuzheng and astragalus polysaccharide injections. Therefore, cinobufagin or kangai injections were preferred in improving the overall response rate and quality of life. Aidi or compound sophora injections were better than other CMIs in reducing? the incidences of nausea (III-IV) and leukopenia. More RCTs of Shenqi Fuzheng and astragalus polysaccharide injections combined with radiotherapy for patients with esophageal cancer were expected in the future to confirm our results. Moreover, study findings will be reported, particularly for the adverse events in radiotherapy for esophageal cancer.

OBJECTIVETo analyze the survival status and prognostic factors of patients with liver metastases from colorectal cancer.

METHODSThe survival rate and prognostic factors of 112 patients with liver metastases from colorectal cancer, who had complete follow-up data, were retrospectively assessed by Kaplan-Meier analysis and multivariate regression analysis.

RESULTSThe median survival time of the 112 patients was 18.25 months. The 1-, 2-, 3- and 5-year overall survival rates were 60.8%, 35.0%, 20.3% and 4.8%, respectively. Univariate analysis demonstrated that gender, age, primary tumor site, chemotherapy and pathological types had no significant correlation with the overall survival. But the treatment of primary tumor, time of liver metastasis, gross type of tumor, resection of liver metastases and clinical stage status were all independently related with the prognosis of patients. Multivariate regression analysis showed that resection of liver metastases, gross type of tumor and clinical stage were key factors affecting the prognosis of patients with liver metastases from colorectal cancer.

CONCLUSIONPatients with advanced stage, infiltrative gross type of colorectal cancer should be followed-up closely so that liver metastases from the cancer can be diagnosed and treated early. Resection of both the primary tumor and liver metastasis may improve survival of the patients.

AIMTo analyze the relationship between autosomal aberrations and testicular dysgenesis or spermatogenic arrest in Chinese patients and to map the corresponding regions on each autosome in regard to the recorded aberrations accompanying these distubances.

METHODSOne hundred and nineteen cases of aberrant karyotypes with testicular dysgenesis, azoospermia or oligozoospermia reported in five Chinese journals and one monograph were analyzed. For each autosome, the type and frequency of chromosomal aberrations were counted and the regions corresponding to the disturbances were mapped out.

RESULTSChromosomes 13, 14, 9, 21 exhibited a high frequency of aberration and bands 14q11 and 13p11 were the two regions showing the highest linkage to testicular dysgenesis or infertility. The frequency of chromosomal aberrations was higher in bands 9p11 and 22q than in others.

CONCLUSIONAutosomes 13, 14, 9 and 21 in the order of importance play a critical role in testicular development and spermatogenesis and other autosomes may also contribute; the following regions, 14q11, 13p11,9p11, and 22q, are of high significance.

Erythroderma with complicated etiology is one of the severe skin diseases and has high mortality,of which the incidence was 0.5％-1.5％ in skin diseases.Erythrodermic psoriasis (EP) is the commonest type of erythroderma.In addition,there are drug-induced erythroderma,erythroderma secondary to preexisting dermatoses,malignancy-related erythroderma,and idiopathic erythroderma of unknown etiology.Erythroderma of different etiologies has various clinical manifestations,resulting in relevant curative effects and outcomes.In this article,we retrospectively investigated 205 erythroderma patients about clinical symptoms,auxiliary examination and treatments,and evaluated the efficacy and prognosis.There were 84 cases of EP among 205 patients,10 cases of erythroderma caused by specific drugs,77 cases of erythroderma secondary to preexisting dermatoses (excluding psoriasis),7 cases of erythroderma patients suffering from malignancy and 27 cases with unknown causes.We concluded that the etiology of male patients in different age groups had significant difference.The incidence of EP was the highest among all types.The EP was commonly accompanied with hypoproteinemia,and changed into psoriasis vulgaris after treatment.Drug-induced erythroderma was commonly accompanied with fever,and mostly cured by systematic steroid therapy.For erythroderma secondary to preexisting der matoses,the original dermatoses must be actively treated to achieve a satisfying prognosis.Erythroderma with malignancy or unknown causes had long-term duration,poor response to the treatment,and high potential to relapse.Therefore,clarifying the etiology,providing an appropiate and individual regimen,and regular follow-up are crucial for the successful treatment of erythroderma with unknown causes.

To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated. Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all <0.001).In the ultra-early stage after surgery,HCR was significantly higher in the KAES group(<0.001),whereas in the early and sub-early stage,HCR showed no significant differences(all >0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all >0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all >0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(=0.413). Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

OBJECTIVETo explore the experience on venoarterial extracorporeal membrane oxygenation (ECMO) in adult patients with cardiac failure.

METHODSFrom February 2005 to June 2008, 45 patients (male 34, female 11) undergoing cardiogenic shock required temporary ECMO support. Average age was (49.0 +/- 14.1) years. Average body weight was (67.0 +/- 12.8) kg. Coronary heart disease occupied in 21 cases, valve disease occupied in 8 cases, and cardiomyopathy occupied in 7 cases. All the patients could be divided into 3 groups: post-cardiotomy (group 1, n = 31), post-transplantation (group 2, n = 5), decompensate of chronic heart failure (group 3, n = 9). Fourteen patients need cardiac resuscitation before ECMO support. ECMO implantation was performed through the femoral vessels or axillary artery or through the right atrium and ascending aorta.

RESULTSAverage support duration of ECMO was (126.7 +/- 104.3) h. Twenty-seven patients could be successfully weaned from support (60.0%), additionally, 5 were bridged to heart transplantation. The in-hospital mortality was 42.2% (19/45). Twenty-six patients (57.8%) could be successfully discharged. The discharge rate was 58.1% in group 1, 4/5 in group 2 and was 4/9 in group 3. Twelve patients were re-operated for hemostasis. Three patients need femoral arterial thrombectomy because of ischemia of lower extremity. Additional intra-aortic balloon pumps were used in 11 patients, with 6 patients successfully discharged. The mortality rate for patients with acute renal failure treated by continuous renal replacement therapy under ECMO support was obviously high (7/9). The dominant mode of death was multisystem organ failure (9/19).

CONCLUSIONEarly indication, control of complications, and paying attention to the treatment after ECMO support could improve our results with increasing experience.
