Objective Toinvestigatethevalueofimagingdiagnosisofthe lymphangioleiomyomatosis( LAM ).MethodsFifteen patients with LAM confirmed by pathological assessment were analyzed retrospectively for radiologic findings.They had chest radiograph, chest highresolution CT (HRCT),abdominal CT, direct lymphangiography(DLG), chest CT and abdominal CT after DLG.Results Chest radiograph findings included normal (1),increasing of lung markings (3),disseminated honeycomb or reticular pattern ( 11 ), pneumothorax ( 2 ), and pleural effusion ( 14 ). Chest conventional CT and HRCT showed typical imaging manifestation of PLAM in all cases, including sporadic or disseminated cysts in bilateral lungs. According to the grading standard of pulmonary disease made by Avila et at, there were 3 cases in grade Ⅰ , 5 cases in grade Ⅱ and 7 cases in grade Ⅲ . Fourteen of 15 patients with LAM had positive abdominal CT findings in retroperitoneum and pelvic cavity. Common abdominal CT findings included cystic lymphangioma in 9 of 14 patients, lymphangiomyoma in 13 and both coexisting in 7.One of the14patients alsohadhepaticlipomaandangiomyolipomas.Onepatienthadrenal angiomyolipomas; and one patient had hysteromyoma. All 15 cases underwent DLG, 1 cases had lymphatic obstruction in the lumbar 3 level, the remaining 14 cases had varying degrees of thoracic duct stenosis, or obstruction. Neck trunk, subclavian trunk and bronchial trunk showed lymphatic reflux. On post-DLG CT,thoracic duet outlet obstruction was not demonstrated in 3 cases, the remaining 12 cases showed thoracic outlet obstruction, consistent with the DLG findings.Conclusion HRCT is a useful diagnostic method showing characteristic findings of PLAM. MSCT can help to detect abdominal LAM. DLG and MSCT after DLG have value in displaying obstruction site of thoracic duct or lymphatic trunks and provide guidance for operative treatment.

Objective To investigate the oxalate-degrading and growth abilities of lactic acid bacteria coming from yoghourt in vitro culture broth. Methods The species of lactic acid bacteria obtained from 6 brands of yoghourt were identified. Different brands of yoghourt were separately cultured in broth and incubated at 37 ℃,5% CO2 for 48 h, getting the concentration of lactic acid bacteria through slab counting method. The brand of yoghourt with the highest quantity of bacteria was chosen as the study subject. Three species of bacteria and the mixture bacteria obtained from the chosen brand of yoghourt were cultured separately for 72 h in MRS broth which contained three different concentrations of ammonium oxalate, and the broth without inoculating of bacterium was prepared as control. The amount of bacteria in culture was detected, the concentration of ammonium oxalate was detected through photometric determination of oxalic acid by its catalytic reaction of methyl red by potassium chromate. Results Three species of lactic acid bacteria (L.bulgaria, L.acidophilus and L.thermophilus) were detected in each brand of yoghourt. The quantity of bacteria in Weiquan yoghourt is the highest. After 72 h incubation, the concentrations of oxalate in all the broths containing bacteria were lower than those in the control. L.acidophilus showed the best degrading activity. The higher the concentration of oxalate was, the bigger the amount of oxalate degraded was, the smaller the percent of degrading was, and the less the growth ability of bacteria was. Conclusion All the species coming from yoghourt have the ability of oxalate degrading, which increases with the concentration of oxalate in culture.But the high concentration of oxalate restrains the growth of bacteria.

Objective To evaluate the therapeutic effect of acupoint catgut embedding on gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury.Methods Sixty-eight consecutively hospitalized patients with gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury admitted to the Department of Intensive Care Unit (ICU) in the First Affiliated Hospital of Zhejiang University of Chinese Medicine from January 2015 to December 2015 were enrolled.Six of those patients were withdrawn from the course of observation,and actually only 62 patients entered the study.They were divided into an observation group (32 cases) and a control group (30 cases) by random number table.All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days.The observation group was additionally treated with acupoint catgut embedding.The control group took mosapride tablets via a nasogastric tube 5 mg,3 times a day.Intra-abdominal pressure (IAP),gastric residual volume (GRV),time for reaching standard enteral nutrition,serum diamine oxidase(DAO),D-Lactate activity,incidence of hospital-acquired pneumonia (HAP),hospitalization days in ICU,28-day mortality and adverse reactions of acupoint catgut embedding were observed in the two groups.Results After treatment,the levels of IAP,DAO,D-lactic acid were lower than those before treatment,GRV was less than that before treatment in the two groups,and after treatment for 7 days the changes were more significant in the observation group [IAP (cmH2O,1 cmH2O =0.098 kPa):12.42±3.11 vs.17.70 ± 2.98,GRV (mL):129.54 ± 57.54 vs.242.91 ± 99.29,DAO (U/L):9.06± 2.84 vs.13.60 ± 7.16,D-Lactate (mg/L):16.47 ± 5.39 vs.26.29 ± 9.62,all P ＜ 0.01].Days of mechanical ventilation (days:6.97 ± 4.13 vs.9.23 ± 4.61),time for reaching standard enteral nutrition (days:4.25 ± 3.15 vs.5.50 ± 3.12) and hospitalization days in ICU (days:9.50± 4.03 vs.12.20 ± 6.38) in observation group were significantly shorter than those in control group (all P ＜ 0.05).The incidence of HAP [15.6％ (5/32) vs.40.0％ (12/30)] and 28-day mortality [3.1％ (1/32) vs.6.7％ (2/30)] in observation group were obviously lower than those in control group.The patients in observation group had no significant adverse reactions of acupoint catgut embedding.Conclusions Acupoint catgut embedding therapy is not only easy to operate,but also can effectively improve gastrointestinal motility and intestinal barrier function in patients with gastrointestinal dysfunction after surgery of severe head injury,thus it is beneficial to reaching the enteral nutritional goal in less time,reducing the incidence of HAP,shortening the hospitalization time in ICU and promoting the recovery of the patients.

Objective To report a case of foot hyalohyphomycosis due to Fusarium subglutinans. Methods Medical history was collected and physical examination performed for this patient.Biopsy samples were obtained from the inner side of right ankle of this patient and subjected to pathological examination. Discharge was collected from the lesions for direct microscopic examination and culture.Results A 72-year-old woman presented with an ulcer on the right foot for 3 years.Physical examination disclosed an ulcer,measuring 3 cm x 1.5 cm,with a moist surface and obvious tenderness,at the inner side of the right ankle.Proliferation of dusky-red granulomatous tissue was observed at the base of the ulcer.Pathological examination revealed necrotic granulomatous tissue and slender,septate and hyaline hypha-like structure in the superficial dermis with scattered infiltration of inflammatory cells.PAS staining showed sausage-like hypha and scattered orbicular-ovate spores.Microscopic examination of lesional discharge exhibited septate, branching and hyaline hypha.The isolated fungus was identified as Fusarium subglutinans by culture,and appeared to be highly sensitive to terbinafine,nystatin and amphotericin B.The lesion completely healed after 2 months of treatment with oral terbinafine (0.25 g,twice a day).Conclusions This is a case of foot hyalohyphomycosis due to Fusarium subglutinans,and terbinafine is effective for this condition.

Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

Objective To investigate the clinical value of serum metabonomic profile of pancreatic cancer using nuclear magnetic resonance (NMR)-based metabonomics.Methods The retrospective case-control study was adopted.The clinical data of 23 patients with pancreatic cancer (PC group) and 16 healthy volunteers (control group) who were admitted to the Fujian Medical University Union Hospital between December 2013 and December 2014 were collected.The serum of the 2 groups was measured by 1H NMR spectroscopy.Multivariate statistical analyses were performed to identify the characteristic metabolites in the 2 groups,including principal component analysis (PCA),partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA).Observation indicators included:(1) multivariate statistical analysis of serum metabonomic profile,results of PCA,PLS-DA and OPLS-DA,(2) screening of metabolites.Measurement data with normal distribution were presented as x ± s.The comparison between groups was evaluated with the t test.The count data were analyzed using the chi-square test.Results (1) The multivariate statistical analysis of serum metabonomic profile:results of PCA showed that expression rates of principal component 1 (PC1) and principal component 2 (PC2) to original data were 54.9％ and 23.5％,with both cumulative contribution rate of 78.4％.Results of PLS-DA showed that the separative trend between PC group and control group was appeared,and variance of X and Y matrixes and predictive value were 0.254,0.816 and 0.385.Results of OPLS-DA showed that the differences of samples between the 2 groups were further increased,and differential metabolites were screened according to the distinction of scores between the 2 groups,value of R2X,R2Y and Q2 was 0.254,0.816 and 0.433.(2) Screening of metabolites:35 serum metabolites were detected in the 2 groups.Compared with the control group,levels of 3-hydroxybuyarate,citrate,formate,glutamate,isoleucine,methionine and phenylalanine in the PC group were elevated (r =0.524,0.511,0.656,0.566,0.503,0.498,0.648,P ＜0.05),and levels of 3-methylhistidine,alanine,glutamine,LDL and VLDL in the PC group were decreased (r =-0.607,-0.508,-0.560,-0.568,-0.559,P ＜ 0.05).Conclusions Compared with healthy controls,several amino acids,citrate and lipoproteins demonstrate the metabolic differences in the serum of patients with pancreatic cancer.NMR based metabonomic profile technology can distinguish the difference of serum metabolites between patients with pancreatic cancer and healthy controls.NMR based metabonomic technology may be a promising method for the diagnosis of pancreatic cancer.

Objective To analyze the metabolic profile in serum between normal and orthotopic xenograft nude mice burdened with three human pancreatic cancer cell lines,which were differentiated differently.Methods Human pancreatic cancer lines SW1990,BxPC-3 and Panc-1 were subcutaneously injected into the nude mice,respectively.When the tumor volume reached 1.0 cm3,the nude mice were euthanized and the tumor tissues were removed and implanted to the pancreas to establish the orthotopic xenograft mice model.The serum from three orthotopic xenograft tumor nude mice and the normal controls were collected and then analyzed by 1H nuclear magnetic resonance spectroscopy.Results The three orthotopic xenograft nude mice models were successfully established.In SW1990,BxPC-3 and Panc-1 group,the orthotopic xenograft tumor formation rate was 79％ (11/14),93％ (13/14) and 86％ (12/14),while the mortality was 7％ (1/14),0 and 7％ (1/14),respectively.Compared with control group,the content of metabolites in the serum of orthotopic xenograft tumor nude mice was increased including creatine,alanine,glutamine,1-methylhistidine,isoleucine,lactate,phenylalanine,tryptophan and valine,but the glycerolphosphocholine (GPC) and glucose levels were reduced.As the tumors progressed to be more malignant,the content of valine and isoleucine tended to increase.Conclusions The establishment of the orthotopic implantation tumor nude mice model was stable and reliable with high tumor formation rate.Obvious metabolic differences of glucose,lipid and amino acids were observed between normal and human pancreatic cancer tumor burdening nude mice models.The common metabolic features identified in all three nude mice models burdened with human pancreatic cancer could be used as the potential markers for diagnosing human pancreatic cancer.
