Objective To investigate the origin of prostatic blood-supply by digital subtraction angiography (DSA) and provide references for the arterial embolization of prostatic hyperplasia. Methods A total of 72 male patients with successful selective and super-selective prostatic arterial catheterization angiographies were observed and recorded the original arterial blood-supply of the prostate, number of the prostatic arteries and the predominant blood supply. Results The blood-supply of prostate is very complicated including the original prostatic arterial supply from the inferior vesicle arteries (69); the internal iliac arteries (63); the internal pudendal arteries (52); the inferior rectum arteries (29); the superior vesicle arteries (14). The predominant arterial supply include the internal iliac arteries (37); the inferior vesicle arteries (20); the internal pudendal arteries (6) and the inferior rectum arteries (2). Conclusion Arterial contrast medium angiography can correctly demonstrate and assess the original arterial supply of prostate, providing significant guidance for further interventional embolization.

Objective To evaluate the advantage of single -source spectrum CT in differentiating of calcifi-cation and tophus.Methods 146 cases of clinical suspected patients with gout pain were scaned by single -source spectrum CT,observed the adjacent to the bone and joint hyperplasia and showing characteristics of gout stone,coun-ted quantity,size and position of the sedimentary tophus.Diagnosed by American rheumatism association standard as the gold standard,computed the sensitivity,specific degrees and accuracy of showing tophus of single -source spec-trum CT and conventional CT,and evaluated the advantage of differentiating adjacent to the bone and joint hyperplasia and gout stone of single -source spectrum CT.Results Diagnosis of gout in 105 cases.Scaned 349 joints,positive in 341 of them,The first plantar toe joint involvement was obvious[118,34.60%(118/341)];The result showed that the sensitivities of the tophus,specific and accurate rate of the conventional CT were 63.80%(67 /105),65.85%(27 /41),64.38%(94 /146),which of single -source spectrum CT were 96.19%(101 /105),87.80%(36 /41), 93.84%(137/146),the differences of sensitivity,specificity and accuracy between the two methods were statistical significance(χ2 =34.42,555,38.34,all P <0.05).Conclusion Single -source spectrum CT in gout stone adjacent to the bone and joint has higher sensitivity and accuracy,specific degree,it is higher than conventional CT and provide a new noninvasive imaging technique for the identification of the peripheral bone and joint of the bone.

Objective To investigate and analyze the health care seeking behavior,financial burden and relative factors of patients with rheumatic diseases in Fujian Province.Methods Patients diagnosed with rheumatic diseases were investigated in Fujian Provincial Hospital from December 2013 to February 2014,including demographic data,health care seeking behavior and financial burden.Relevant factors were analyzed by Logistic regression.Results ① In this study,474 patients were enrolled.The ratio of male to female was 1∶2.38.② At the onset of symptoms,51.9％(246 cases) of patients visited a doctor as soon as possible,and 36.1％(171 cases) of them went to hospital within a month after disease onset.③ 74.1％(351 cases) of patients could adhere to medication regimen prescribed by doctors,and the most common reason for stopping medication was symptoms relieved (33.3％,41 cases).④ 63.1％(299 cases) of patients learned about the knowledge of rheumatic diseases from hospitals and doctors.⑤ 34.2％(162 cases) of patients spent 1 000-5 000 yuan every month on treatment.⑥ Insurance type could affect the time of first visit to hospital (P=0.004),while income and cost of therapy might impact patients' compliance (P=0.013,P=0.004).Conclusion Most patients will go to hospital as soon as possible and adhere to treatment.Economic situation is the main factor influencing health care seeking behavior of patients with rheumatic diseases.

Objective To investigate the changes of pathogens distribution and antimicrobial resistance in children with urinary tract infection (UTI) in 10 years. Methods The results of urine culture and drug sensitivity in children with UTI from January 2001 to December 2003, and from January 2011 to December 2013 were retrospectively analyzed.Results In recent 10 years, there was no obvious change in the ratio of gram-negative bacteria to gram-positive bacteria. Escherichia coli was still the main bacteria causing UTI in children. The detection rate of enterococcus was signiifcantly increased from 18.3%in 2011-2013 to 7.5%in 2001-2003 (P<0.05) and it had become the second pathogenic bacteria. The isolation rate of ESBLs producing strains was signiifcantly higher in 2011-2013 than in 2001-2003 (P<0.05). The rate of Escherichia coli sensitive to imipenem re-mained at 100%and it is also sensitive to enzyme inhibitors antibiotics and nitrofuranto. Sensitivities to antibiotics were changed in different species of enterococcus. Conclusions The distribution of pathogens and antimicrobial resistance in children with UTI are constantly changing. The clinician should pay close attention to changes of epidemiology in the region and hospital and rational use of antimicrobial drugs.

The clinical analgesic effect of electro-acupuncture (EA) stimulation (EAS) on breakthrough pain induced by remifentanil in patients undergoing radical thoracic esophagectomy, and the mechanisms were assessed. Sixty patients (ASAIII) scheduled for elective radical esophagectomy were randomized into three groups: group A (control) receiving a general anesthesia only; group B (sham) given EA needles at PC4 (Ximen) and PC6 (Neiguan) but no stimulation; and group C (EAS) electrically given EAS of the ipsilateral PC4 and PC6 throughout the surgery. The EAS consisting of a disperse-dense wave with a low frequency of 2 Hz and a high frequency of 20 Hz, was performed 30 min prior to induction of general anesthesia and continued through the surgery. At the emergence, sufentanil infusion was given for postoperative analgesia with loading dose of 7.5 μg, followed by a continuous infusion of 2.25 μg/h. The patient self-administration of sufentanil was 0.75 μg with a lockout of 15 min as needed. Additional breakthrough pain was treated with dezocine (5 mg) intravenously at the patient's request. Blood samples were collected before (T1), 2 h (T2), 24 h (T3), and 48 h (T4) after operation to measure the plasma β-EP, PGE2, and 5-HT. The operative time, the total dose of sufentanil and the dose of self-administration, and the rescue doses of dezocine were recorded. Visual Analogue Scale (VAS) scores at 2, 12, 24 and 48 h postoperatively and the incidence of apnea and severe hypotension were recorded. The results showed that the gender, age, weight, operative time and remifentanil consumption were comparable among 3 groups. Patients in EAS group had the lowest VAS scores postoperatively among the three groups (P<0.05). The total dose of sufentanil was 115±6.0 μg in EAS group, significantly lower than that in control (134.3±5.9 μg) and sham (133.5±7.0 μg) groups. Similarly, the rescue dose of dezocine was the least in EAS group (P<0.05) among the three groups. Plasma β-EP levels in EAS group at T3 (176.90±45.73) and T4 (162.96±35.00 pg/mL) were significantly higher than those in control (132.33±36.75 and 128.79±41.24 pg/mL) and sham (136.56±45.80 and 129.85±36.14 pg/mL) groups, P<0.05 for all. EAS could decrease the release of PGE2. Plasma PGE2 levels in EAS group at T2 and T3 (41±5 and 40±5 pg/mL respectively) were significantly lower than those in control (64±5 and 62±7 pg/mL) and sham (66±6 and 62±6 pg/mL) groups. Plasma 5-HT levels in EAS group at T2 (133.66±40.85) and T3 (154.66±52.49 ng/mL) were significantly lower than those in control (168.33±56.94 and 225.28±82.03) and sham (164.54±47.53 and 217.74±76.45 ng/mL) groups. For intra-group comparison, plasma 5-HT and PGE2 levels in control and sham groups at T2 and T3, and β-EP in EAS group at T3 and T4 were significantly higher than those at T1 (P<0.05); PGE2 and 5-HT levels in EAS group showed no significant difference among the different time points (P>0.05). No apnea or severe hypotension was observed in any group. It was concluded that intraoperative ipsilateral EAS at PC4 and PC6 provides effective postoperative analgesia for patients undergoing radical esophagectomy with remifentanil anesthesia and significantly decrease requirement for parental narcotics. The underlying mechanism may be related to stimulation of the release of endogenous β-EP and inhibition of inflammatory mediators (5-HT and PGE2).

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo investigate the impact of surgical resection extent and other clinicopathological characteristics on the prognosis in patients with clinical stage I endometrial carcinoma.

METHODSThe data of 135 surgically treated patients with clinical stage I endometrial carcinoma were retrospectively analyzed. Fifty-seven patients (group A) underwent simple hysterectomy and salpingo-oophorectomy with or without pelvic lymphadenectomy. The other 78 patients (group B) received sub-radical or radical hysterectomy and salpingo-oophorectomy with or without pelvic lymphadenectomy. The impact of surgery extent and other clinicopathological characteristics on the prognosis in patients with clinical stage I endometrial carcinoma were retrospectively analyzed.

RESULTSThere were no significant differences between two groups in the pathological stage, pathologic type, tumor grade, depth of myometrial invasion, vascular tumor emboli, ovary invasion, lymph node metastasis, positive peritoneal cytology and adjuvant therapy (P > 0.05). However, the patients in group A had a significantly shorter operating time (105 vs. 145 min), less estimated blood loss (150 vs. 300 ml) and blood transfusion (0 approximately 600 vs. 0 approximately 1200 ml), and a shorter postoperative hospital stay (12 vs. 13 days) than that in group B (all P < 0.05). The overall rates of post-operative complications were 15.8% in group A versus 26.9% in group B (P > 0.05). The recurrence rate in the group A was 14.0% versus 6.4% in group B (P > 0.05). Furthermore, the five-year survival rate in group A was 76.9% versus 85.8% in group B (P > 0.05). Multivariate analysis demonstrated that the important risk factors for clinical stage I endometrial carcinoma were deep myometrium invasion, high pathological grade, positive peritoneal cytology and ovarian metastasis, rather than surgical resection extent.

CONCLUSIONSurgery extent is not an important factor affecting the prognosis in patients with clinical stage I endometrial carcinoma, and extended surgery does not improve their survival. Therefore, excessive resection should be avoided in such cases.
