Objective To evaluate the effects of different dialysis treatment on femoral artery elasticity in uremia patients by Echo-tracking technique. Methods 81 cases of uremia patients (42 peritoneal dialysis patients and 39 hemodialysis patients) and 31 cases of normal adults as control were recruited in this study. The Intima-media thickness (IMT), Internal systolic diameter (Ds), Internal diastolic diameter (Dd), Value difference between Dd and Ds (△D), Arterial stiffness (β), Pressure strain elastic modulus (Ep), Arterial compliance (AC), Pulse wave conducting velocity (PWVβ) and Augmentation index(AI) parameters were analyzed for evaluation the right femoral arterial elasticity. Results The parameters ofβ, Ep, PWVβin dialysis patients significantly increased (P<0.05) and their AC significantly decreased (P<0.05) compared with normal group. Theβand Ep in hemodialysis patients is higher that those patients not receiving dialysis (P<0.05). Theβand Ep in peritoneal dialysis patients is lower that those patients not receiving dialysis (P<0.05). Theβ, Ep and PWVβin hemodialysis patients are higher than those in peritoneal patients (P<0.05). And AC is lower than control group (P<0.05). In uremia patients, Vascular stiffness was positively correlated with age, duration of dialysis, IMT, pulse pressure, Dd, and negatively correlated with△D(P<0.05). Conclusions Femoral artery endothelial function in uremia patients was damaged earlier than morphological changes. Vascular intimal injury resulting from hemodialysis is more serious, and vascular elasticity decrease is correlated with age, dialysis duration and pulse pressure. Echo-tracking technique could provide quantification evidences for early diagnosis of the femoral artery endothelial dysfunction in uremia patients. The echo-tracking technique has certain significance in early intervention and improvement the prognosis, however, the influence factor of the accuracy of measurement should be consider during the procedure.

CD4+ ..CDS+ -.CD4+ /CDS+ was decreased more significantly in those patients who were older, severe, demential and depressive. Conclusion:Severe natural kill cell and T lymphocyte immune functional decline and disbalance were observed in PD patients. The significant decline of the levels of CD3+ ,CD4+ .CD8+ ,CD4+ /CD8+ in PD patients might be closely related to it's pathogenesis. The levels of CD3+ ,CD4+ ,CD8+ CD4+/CD8+ was even significantly lower in older, severe,dementia and depressive patients, so the levels of natural kill cell and T lymphocyte subsets can provide basis for evaluating severity .progression and prognosis of disease in PD. It was a new connotation for the study of PD on prevention and therapy in the future.

Objective To summarize and evaluate the clinical feature and misdiagnosis of pulmonary granulomatosis with polyangitis (GPA).Methods The clinical data of 47 patients of pulmonary GPA were analyzed retrospectively.The clinical feature and misdiagnosis were summarized.Results These patients were most commonly misdiagnosed as pulmonary infectious disease (61.8％,34/55) and pulmonary malignancy (27.3％,15/55) was the next in line.70.2％(33/47) patients had nose and sinus involvement,40.4％(19/47) patients had kidney involvement,25.5％ (12/47) patients had rash,19.1％(9/47) patients had eyes involvement,6.4％ (3/47) patients had peripheral neuritis,6.4％ (3/47) patients had gastrointestinal bleeding,4.3％(2/47) patients had pericardial effusion,87.2％(41/47) patients had positive for antineutrophil cytoplasmic(cANCA),76.6％(36/47) patients had positive for proteinase-3.Conclusions Almost all pulmonary GPA patients have extra-pulmonary multi-systemic involvement.They are often misdiagnosed as pulmonary infectious diseases and malignancy.Educating doctors on GPA constantly and screening possible patients with cANCA testing may help reduce the misdiagnosis.

This study aimed at investigating the effects of Guttiferone K (GUTK),a polycyclic polyprenylated acylphloroglucinols (PPAPs) compound isolated from Garcinia yunnanensis,on the cell proliferation of human prostate cancer LNCaP cell line.Human prostate cancer LNCaP cells in the period of logarithmic phase were treated with GUTK.MTI assay was used to detect cell proliferation.Flow cytometry of propidium iodide (PI) staining,BrdU assay and immunocytochemistry were adopted to analyze the cell cycle phase distribution.Protein levels of Cyclin A,p27 and SKP2 were detected by western blotting.The results showed that GUTK inhibited the proliferation and induced G0/1 arrest of LNCaP cells in a time and dose dependent manner.The protein levels of Cyclin A and SKP2 were decreased,while p27 was increased by GUTK in human prostate cancer LNCaP cells.It was concluded that GUTK,a compound isolated from G.yunnanensis,presented the effect of inhibiting the cell proliferation by inducing G0/1 arrest of human prostate cancer LNCaP cells,with potential anti-prostate cancer action.

We analyzed genetic evolution characteristics of avian influenza A (H7N9) virus isolated in Zhaoqing,China,2014-2016.Nucleic acid were extracted and sequenced from 17 samples of H7N9 positive cases in Zhaoqing.Genetic characteristics of homology and important amino acid sites were analyzed by using BioEdit5.0 and MEGA6.0.The evolutionary trees were constructed by Neighbor-Joining and the referenced sequences were downloaded from GenBank,Eight nucleic acid fragments from 7 strains of H7N9 viruses were successfully generated.The highest homology was found in HA gene with A/chicken/Dongguan/695/2014(H7N9),and NA gene with A/chicken/Dongguan/1075/2014(H7N9).The internal genes were high homology with avian H7N9 and H9N2 virus from Dongguan and Shenzhen in Guangdong,China.The HA and NA genes were directly evolved in the Pearl River Delta evolution branch with the H7N9 sequences from the cities of Dongguan,Guangzhou and Shenzhen,while the sequences from the provinces of Anhui,Zhejiang,and Jiangsu were in the Yangtze River Delta evolution branch.There were 2 alkaline amino acids in cleavage site of HA,2 mutations (G186V and Q226L) in the crucial sites related with the receptor of HA protein,1 mutation (E627K) in PB2 protein,and 1 drug resistance mutation (S31N) in M2 protein.And no evidence of neuraminidase resistance in NA protein was found.In conclusion,the H7N9 virus for human infection in Zhaoqing may originate from avian H7N9 and H9N2 viruses,which circulated in the Pearl River Delta region of Guangdong from 2013 to 2014.The mutations of G186V,Q226L and E627 K might be related with high susceptibility to human beings.

Based on ancient literature of acupuncture in Canon of Chinese Medicine (4th edition), the articles regarding acupuncture for urinary incontinence were retrieved and collected to establish a database. By Weka data mining software, the multi-level association rules analysis method was applied to analyze the acupoints selection characteristics and rules of ancient acupuncture for treatment of urinary incontinence. Totally 356 articles of acupuncture for urinary incontinence were collected, involving 41 acupoints with a total frequency of 364. As a result, (1) the acupoints in the yin-meridian of hand and foot were highly valued, as the frequency of acupoints in yin-meridians was 2.6 times than that in yang-meridians, and the frequency of acupoints selected was the most in the liver meridian of foot-jueyin; (2) the acupoints in bladder meridian of foot-taiyang were also highly valued, and among three yang-meridians of foot, the frequency of acupoints in the bladder meridian of foot-taiyang was 54, accounting for 65.85% (54/82); (3) more acupoints selected were located in the lower limbs and abdomen; (4) specific acupoints in above meridians were mostly selected, presenting 73.2% (30/41) to the ratio of number and 79.4% (289/364) to the frequency, respectively; (5) Zhongji (CV 3), the front-mu point of bladder meridian, was seldom selected in the ancient acupuncture literature, which was different from modern literature reports. The results show that urinary incontinence belongs to external genitalia diseases, which should be treated from yin, indicating more yin-meridians be used and special acupoints be focused on. It is essential to focus inheritance and innovation in TCM clinical treatment, and applying data mining technology to ancient literature of acupuncture could provide classic theory basis for TCM clinical treatment.

Rapid detection and classification of bacteria colonies ( Escherichia coli, Listeria monocytogens and Staphylococcus aureus) were investigated by using hyperspectral imaging. The hyperspectral reflectance images (390-1040 nm ) of bacterial colonies on agar plates were collected. Bacterial spectra were extracted automatically based on the masks produced by segmenting a band difference image using the OTSU method. Full wavelength and simplified PLS-DA models were established for classification of bacterial colonies. For the full wavelength model, the overall correct classification rate ( OCCR) and confident OCCR for the prediction set were 100% and 95. 9%, respectively. Besides, competitive adaptive reweighted sampling ( CARS), genetic algorithm ( GA ) and least angle regression-least absolute shrinkage and selection operator ( LARS-Lasso) were used to select feature wavelengths for the development of simplified models. Among them, the CARS-model outperformed the other two in terms of precision, stability and classification accuracy with OCCR and confident OCCR of 100% and 98. 0% for the prediction set, respectively. It was demonstrated that hyperspectral imaging was an effective technology for nondestructive detection of bacterial colonies with high accuracy and high speed. The allocated feature wavelengths by CARS could lay theoretical basis for developing low cost multispectral imaging systems for bacterial colony detection.

Objective To analyze the therapeutic efficacy and treatment related toxicities for patients with locally advanced cervical cancer treated with three-dimensional conformal radiotherapy (3DCRT) combined with concurrent chemotherapy. Methods From January 2007 to February 2008, 181 patients with stage ⅡA-ⅣA cervical cancer were retrospectively analyzed. All patients were treated with CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent weekly cisplatin-based chemotherapy. The median age was 50 years (range, 32 to 82 years). The overall survival ( OS), disease-free survival (DFS) and local control (LC) rates were calcalated by Kaplan-Meier method and the difference was compared using Log-rank test. The treatment related toxicities were evaluated according to Radiotherapy Oncology Group (RTOG) criteria. Results With a median follow-up time of 34 months and following rate of 92. 2%, the 3-year OS, DFS and LC rates were 73.4%, 70. 4% and 91.3%,respectively. The 3-year OS rate was 66. 9% for patients with tumor diameter ≥4 cm and 86. 4% for those with tumor diameter ＜4 cm( χ2 =6. 29 ,P =0. 012). The incidences of grade 1 and grade 2 acute toxicities of the lower gastrointestinal tract and the genitourinary system were 40. 0% ,45.0% and 19. 9% ,4. 4%,retrospectively. There were no grade 3 or more acute toxicities. The incidence of grades 3 or 4 late toxicities of the lower gastrointestinal tract was 4. 9%. Conclusions CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent chemotherapy can achieve good therapeutic effects for locally advanced cervical cancer. The acute and late toxicities are significantly reduced compared with historic controls as a result of incorporation of 3DCRT technique.
