Objective To study the feasibility of laparoscopic procedures in the treatment of ectopic pregnancy with hemorrhagic shock. Methods Laparoscopic procedures were carried out in 35 patients with ectopic pregnancy concurrent with hemorrhagic shock. Patients' blood pressures were all above 60/30 mmHg, and B-ultrasonography revealed the intra-abdominal blood loss

Objective To study the correlation between pain, lower limb strength and physical function in patients with primary osteoporosis. Methods Fifty-seven female patients diagnosed with menopause-related low bone mass or primary osteoporosis using a GE calcaneus bone density detector were involved in this study. The muscle strength of their lower limbs was tested with a Biodex system 4 machine. Pain was assessed with a visual analogue scale, and physical function (PF) with the SF-36 instrument. Results Low back pain was significantly correlated with PF, and so was leg pain. Leg pain was also significantly correlated with the strength of the extensors of the dominant leg during low velocity and medium velocity movement. Leg pain was not, however, significantly correlated with the strength of the flexors of the dominant leg during low and medium velocity movement. Conclusions Pain predicts poor physical function in patients with primary osteoporosis or low bone density. During low and medium velocity movement, leg pain significantly predicts poor muscle strength in the extensors of the dominant lower leg, but it has no correlation with the muscle strength of the flexors.

Objective:To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately,and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.

Objective To establish an automatic synthesis method for 11C-carfentanil (CFN) as an novel opiate receptor radioligand and study its biodistribution in rats. Methods 11C-Triflate-CH3 was bubbled into 0.5 mg precursor desmethyl-CFN (which was dissolved in 0.15 ml DMSO) to generate 11C-CFN in a V-tube at room temperature. Sep-Pak C2 column was used for purification of 11C-CFN, which was eluted by 3ml binary system aqueous solution, 10 ml water thrice, and then I ml ethanol. The biodistribution (% ID/g) of 11C-CFN in SD rats was studied. SPSS 13.0 was used for statistical analysis. Non-normal distribution data were analyzed using nonparametric test. Results The synthesis time for 11C-CFN was 20 min (end of bombardment, EOB). The synthesis yield was (35.5 ± 2.2) % on average (n = 12, uncorrected)with the radiochemical purity over 98%. Biodistribution study in rats showed that the tracer had a high brain uptake, rapid blood clearance, and a metabolic pathway via liver and kidney. The highest tracer uptake was in thalamus (4.26 ± 0.89) % ID/g and striatum (4.05 ± 1.08) % ID/g at 5 min after injection, followed by cerebral cortex (2.63±0.89) %ID/g, pons (2.26 ±0.57) % ID/g, hippocampus (2. 17 ±0.55) %ID/g and cerebellum (2. 15 ±0.39) %ID/g. Conclusions The automatic synthesis of 11C-CFN is fast and reliable, and this radioligand can be used for opiate receptor imaging.

Objective To investigate the glucose metabolic pattern of brain functional loop in patients with refractory obsessive compulsive disorder (OCD) using 18 F-FDG PET.Methods Eight patients with refractory OCD and 8 age- and gender-matched healthy volunteers underwent 18F-FDG PET brain imaging.SPM software was used for image post-processing and quantitative analysis.Correlation analysis between 18F-FDG uptake and Yale-Brown obsessive compulsive scale(Y-BOCS) score was performed.Results Compared with the controls,the glucose metabolism of bilateral frontal cortices ( including the rectal gyrus,orbital gyrus and cingulate gyrus),left thalamus,right temporal lobe and bilateral cerebellum in refractory OCD patients increased significantly ( Zmax =3.45 - 5.80,all P ＜ 0.001 ).Bilateral motor cortices and bilateral parietal lobes (BA7),however,showed decreased glucose metabolism (Zmax =3.44 - 4.46,all P ＜0.001 ).Y-BOCS score was positively correlated with the glucose metabolism of the bilateral anterior cingulate cortex (Zmax =3.77,3.48 and 2.97,all P ＜ 0.01 ).Conclusions There is a characteristic metabolic pattern of increased glucose utilization in the fronto-striato-thalamic loop and decreased glucose utilization in bilateral motor cortices and parietal lobes in patients with OCD.The glucose metabolism in the anterior cingulate cortex might serve as a quantitative parameter for the assessment of the severity of OCD.

Objective To explore the effect and potential mechanism of Huayu Mingmu Recipe(HMR)-containing serum on high glucose-induced angiogenesis of human retinal microvascular endothelial cells(HRMECs).Methods CCK-8 method is used to screen the optimal sugar concentrations,as well as volume fraction of drug-containing serum.A model of high glucose-induced HRMECs dysfunction was established.The HRMECs were divided into 6 groups such as normal control group which was treated with normal ECM culture medium(containing 5.5 mmol·L-1 glucose)and 10%blank serum,the mannitol control group and the high glucose model were given 19.5 mmol·L-1 mannitol and 19.5 mmol·L-1 D-glucose on the basis of the treatment of normal control group,respectively.The low-,medium-,and high-dose groups of HMR were given 10%low-,medium-,and high-dose medicated serum(without blank serum)on the basis of the model group.The colony experiment was used to detect the number of cell colonies.Transwell experiment was used to test the number of cell migration,and tube formation experiment was used to determine the forming of tubes.Immunofluorescence,Western Blot and RT-PCR were used to detect levels of protein and mRNA expression of FactorⅧ,platelet endothelial cell adhesion molecule-1(CD31),cell differentiation factor(CD34),vascular endothelial growth factor A(VEGFA),vascular endothelial growth factor receptor 2(VEGFR2).Results Compared with the normal control group,the model group could promote colony formation of HRMECs(P＜0.01),cell migration(P＜0.01),and lumen formation(P＜0.01).The levels of protein and mRNA expressions of Factor VIII,CD31,CD34,VEGFA,VEGFR2 were significantly increased(P＜0.01)in model group.Compared with the model group,low-,medium-and high-dose HMR-containing serum groups could inhibit colony formation of HRMECs(P＜0.05,P＜0.01),cell migration(P＜0.01),and lumen formation(P＜0.05,P＜0.01).The levels of protein and mRNA expressions of Factor VIII,CD31,CD34,VEGFA,VEGFR2 were significantly reduced(P＜0.05,P＜0.01)in HMR-containing serum groups.There was no statistically significant difference in results of various tests between the normal control group and the mannitol control group(P＞0.05).Conclusion HMR-containing serum can inhibit the proliferation,migration,and tube formation of HRMECs induced by high glucose,and then prevent or reduce angiogenesis.The mechanism may be related to the regulation of VEGFA/VEGFR2 signaling pathway.

OBJECTIVETo evaluate the feasibility of PCR/reverse line blot hybridization (RLB) assay in the detection and identification of clinical pathogens in fungal sinusitis (FS).

METHODSTwenty-six formalin-fixed and paraffin-embedded tissues and 8 fresh tissues of FS were collected from Beijing Tongren Hospital, Capital Medical University from May 2009 to February 2010. Pathological examination, fungal culture and ITS2 region sequencing were carried out. The DNA of all samples was extracted by standard procedure and fungal universal primers ITS3 and ITS4 were used for PCR amplification of all tissues. Then the amplified products were used for RLB with five fungal species-specific probes. The results of PCR/RLB were compared with ITS region sequencing, fungal culture and pathological examination.

RESULTSFor the biopsy tissues, fungal cultures were positive in 14 cases (41.2%); pathologic examination demonstrated fungal hyphae in all cases; ITS2 region sequencing was successful in 16 cases (47.1%); PCR/RLB showed A. flavus in 14 cases, A. fumigatus in 10 cases, A. niger in four cases, A. nidulans in one case, A. flavus and A. fumigatus in three cases, and A. fumigatus and A. niger in two cases.

CONCLUSIONSThe PCR/RLB assay is suitable for rapid and accurate detection and identification of the pathogenic fungus of FS. Compared with the conventional fungal culture and microscopy, pathologic examination and DNA sequencing, the PCR/RLB has the advantages of more economy, time saving, and higher sensitivity, specificity and throughput.

This study compared the efficacy and safety of tiotropium bromide inhalation powder (spiriva) and doxofylline oral tablet (doxofylline) in the treatment of chronic obstructive pulmonary disease (COPD). A multi-center, randomized, double-blind, double-dummy, parallel-controlled study involved 127 eligible stable moderate to severe COPD patients treated with inhaled tiotropium dry powder (18 μg/day) or oral doxofylline tablets (0.2 g/time, 2 times a day) for 12 and 24 weeks. Before and after treatment for 12 weeks and 24 weeks, respectively, pulmonary function, 6-min walking distance and dyspnea index were recorded. The results showed that in both tiotropium group and doxofylline groups, after 12-week treatment, FEV(1), FEV(1)/FVC% and 6-min walk distance were significantly higher than those before the medication, while dyspnea index decreased as compared with that before treatment. After 24-week treatment, a slight improvement in the measures was observed as compared with that of 12-weeks treatment, but the difference was not statistically significant. With both 12-week and 24-week treatment, the effect of tiotropium was slightly better than that of doxofylline tablets, with the difference being statistically insignificant. The major adverse events in the tiotropium group and doxofylline group were observed in 9 cases (9.9%) and 12 cases (12.9%), respectively, and no statistically significant difference was found between them. We are led to conclude that both tiotropium at 18 μg a day and doxofylline tablets at 0.2 g/day (two times a day) are effective and safe for the treatment of COPD.
