Objective:We aimed to explore the clinical features, computed tomography (CT) findings, treatment, and prognosis of bronchopulmonary carcinoid. Methods:Clinical data of 31 patients with primary carcinoid tumor of the lung were retrospectively re-viewed. The prognostic factors were analyzed via Cox univariate and multivariate analyses. Results: Clinical symptoms included coughing or expectoration in 17 of the 31 cases, hemoptysis or blood-stained sputum in 7 cases, and chest pains or shortness of breath in 8 cases. Six cases were asymptomatic. The CT scans showed round or oval nodules with clear boundaries, and enhancement CT scans indicated mild, homogeneous enhancement. Immunohistochemistry results revealed the positive expression rates of synaptophy-sin (Syn), chromogranin A (CgA), and neuron-specific enolase (NSE) were 90.3%(28/31), 87.1%(27/31), and 90.3%(28/31), respec-tively. Therapy and prognosis results were as follows:28 of the total number of patients underwent surgery, among which 3 underwent postoperative adjuvant therapy, 2 received chemotherapy; and only 1 refused treatment. The 1-year overall survival rates were 100%(18/18) and 92.3%(12/13), whereas the 3-year survival rates were 94.4%(17/18) and 69.2%(9/13) in the typical and atypical carcinoid cases, respectively. Cox univariate analysis results revealed that lymphatic metastasis (P=0.02), tissue types (P=0.017), TNM stage (P=0.005), and therapies (P=0.01) were the prognostic factors. Cox multivariate analysis results showed that lymphatic metastasis (P=0.032) and tissue types (P=0.002) were the independent prognostic factors. Conclusion:Compared with other lung cancers, the bron-chopulmonary lung carcinoid has no special clinical manifestation in clinical and radiographic images. The diagnosis was mainly based on histopathology results. Surgery was the main and effective treatment, whereas chemotherapy and radiotherapy showed unsatisfactory results. The overall prognosis was satisfactory. However, the atypical carcinoid was inferior to the typical carcinoid in terms of progno-sis. Pathological typing and lymph node metastasis were significant prognostic factors.

OBJECTIVETo investigate the treatment for tibial exposure wounds.

METHODS39 patients with tibial exposure wounds were divided into three groups according to the exposure location (upper, medium and below). The local muscular flaps were designed to cover the tibial exposure, followed by skin grafts and VSD. VSD was removed one week later.

RESULTSAll the muscular flap and skin graft survived. Mild epidermis erosion happened in 2 cases, which healed spontaneously after dressing. The patients were followed up for 3-6 months with good healing and no walking malfunction.

CONCLUSIONSThe local muscular flap combined with skin graft and VSD is a simple and effective method for tibial exposure wound with short healing time and high successful rate.

Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Objective 　To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods　253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results　Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions　Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.

Objective To investigate the compound donkey-hide gelatin syrup in reducing adverse reactions of qi-blood weakness patients caused by clozapine.Methods 132 patients from Psychiatric Hospital of Yunnan Province between January 2010 and June 2010 were randomly divided into a treatment group and a control group.Both groups were taken clozapine orally.On this basis,the treatment group was taken compound donkey-hide gelatin syrup and the control group was taken placebo syrup.After 8 weeks treatment for both groups,the PANSS,TESS,physical examination and experiment examination were observed to evaluate the clinical efficacy and safety.Results ① the total curative effect:the treatment group was 73.53％,the control group was 65.63％,showing statistical difference (x2=2.543,P＜0.05).② PANSS scores changes before and after the treatment:PANSS score at 2,4,6,8 weeks after the treatment of both groups were [(72.51 ±27.55),(60.54±24.03),(53.12± 15.27),(48.15± 11.88) in treatment group respectively,and (70.71 ±23.90),(58.89± 18.95),(53.06± 14.38),(48.98 ± 9.78) in the control group,respectively],both showing significant difference than the same group before the treatment [(103.99±39.12) in the treatment group,(99.78±34.35) in the control group] (P＜0.05).But there was no statistical significance between two groups (F=2.413,P＞0.05).③ adverse reactions:during the treatment liver function,blood cell analysis,dystonia,Parkinson's obstacle,akathisia,abnormal gastrointestinal reaction,heart rate,heart rate variability and blood pressure in the treatment group was significantly lower than the control group (x2=4.562,P＜0.05).Conclusion Compound donkey-hide gelatin syrup can effectively relieve adverse reactions in qi-blood weak psychosis patients after clozapine treatment and improve their drug tolerance.

Objective To investigate the short axis systolic function of children with single-left ventricle(LV),and to appraise the clinical value of velocity vector imaging(VVI) on assessing it.Methods The study group consisted of 14 patients with single-LV.The control group consisited of 14 age-matched normal children.VVI was used to analyse the circumferential and radial strain and strain rate of regional single-LV at the level of papillary muscle.Results Compared with values in control group,single-LV circumferential strain values were significantly lower in anterior septum,posterior septum,anterior wall,lateral wall and inferior wall(all P ＜0.05).Single-LV circumferential strain rate values were significantly lower in anterior septum,posterior septum,anterior wall,lateral wall and posterior wall compared with controls(all P ＜0.05). In control group,circumferential strain and strain rate were higher in inferior septum and anterior septum compared with other segments( P ＜0.05).Single-LV radial strain values were significantly lower in all segments compared with values in control (P ＜ 0.05).In control group,radial strain and strain rate of papillary muscle level showed no significantly difference( P ＞0.05).Conclusions Circumferential and radial systolic ventricular function are impaired in children with single-LV.VVI can beused as a quantitative tool in evaluating the short axis systolic function of single-LV.

Objective To investigate the characteristics of blood donors’psychological activity,take reasonable intervention measures to improve the success rate of blood donation recruitment and the ratio of repeated blood donation.Methods The data of blood donors’psychological activity was collected by distributing questionnaires randomly,and the psychological characteristics and worries were analysed.Results In terms of the blood donation purpose,there were 62.73% of the blood donors who donate blood for the first time and take the“utility psychological”as the principal thing.There were 76.01% of the blood donors who donate blood repeatedly and take the“dedication psychological”as the principal thing.In terms of wor-ries,there was 72.69% of the blood donors who donate blood for the first time and take the“safety of blood donation”as the principal thing.There was 77.91% of the blood donors who donate blood repeatedly and take the “service quality of blood donation”as the principal thing.Conclusion The success rate of blood donation recruitment and the ratio of repeated blood donation could be effectively improved by attaching importance to the psychological needs and worries of blood do-nors,by taking different psychological intervention measures strategies for different kinds of blood donors,and by meeting their needs and eliminating their worries.

Objective To investigate the difference of effect between interventional treatments and intravenous therapy of lidamycin on VX2 rabbit liver cancer.Methods VX2 Carcinoma cells were surgically implanted into the left liver lobe of 12 New Zealand white rabbits to establish the VX2 rabbit liver tumor model.Tumor size was detected by type-B ultrasonic diagnostic instrument.The rabbits were randomly divided into two groups of six,respectively treated with the hepatic inter-ventional administration of lidamycin (LDM)(1 ml,0.05 mg/kg)under the guidance of digital subtraction angiography (DSA)(group A)and with the auricular intravenous administration of LDMat the same dose (group B).All the rabbits were sacrificed and anatomized on day 10 after treatment,whose liver tumor was fixed with 4% paraformaldehyde solution and embedded in paraffin.Proliferating cell nuclear antigen (PCNA)and CD34 expression in the sample sections of tumor tissue were assessed through immunohistochemical staining.The levels of alanine transaminase (ALT)and aspartate trans-aminase(AST)were detected by Cobas 8000.Finally,the inhibition of VX2 tumor was evaluated.Results The VX2 tumor volumes were all increased at 10 day after LDMtreatment.However,the tumors in group A were smaller than those of group B (P <0.05).The results of immunohistochemistry showed that the intervention therapy of LDM could further lower the expression of CD34 and PCNA compared to group B.Conclusion Hepatic interventional administration of LDM under the guidance of DSA produces a better effect on attenuating the tumor growth than the intravenous administration of LDM.

Objective To investigate the clinical characteristics,distribution and drug sensitivity of pathogens causing intravenous catheter-related bloodstream infections (CRBSIs) in pediatric intensive care unit (PICU) so as to use antibiotics reasonably.Methods All patients with CRBSIs in PICU of Guangdong General Hospital from September 2009 to September 2014 were investigated and the drug resistance profiles of pathogens causing CRBSIs were also analyzed retrospectively.Results Between 2009 and 2014,there were totally 10 834 catheter days and 23 episodes of CRBSIs with an incidence of 2.1 infections per 1 000 catheter days.Catheter indwell time ＜ 7 days in 9 cases (39.1％),8 to 14 days in 10 cases (43.5％),14 to 21 days in 4 cases (17.4％).There were 13 strains (56.6％) of gram-positive bacteria,5 strains (21.7％) of gram-negative bacteria and 5 strains (21.7％) of fungi.The main pathogens causing CRBSIs were coagulase negative Staphylococci (7 strains,30.4％),Staphylococcus aureus (3 strains,13.0％),Candida albicans(3 strains,13.0％),Candida parapsilosis(2 strains,8.7％),and Enterobacter cloacae (2 strains,8.7 ％).The susceptibility to Vancomycin,Linezolid and Teicoplanin of coagulase negative Staphylococ cus such as S.epidermidis and to Imipenem,Piperacillin/Tazobactam,Cefoperazone/ Sulbactam and Amikacin of gram-positive bacteria arrived at 100.0％,respectively.The candida were 100％ susceptible to Amphotericin B,5-Flucytosine,Fluconazole and Voriconazole.Twenty-one cases (91.3％) received antibiotic treatment versus no antibiotic in 2 cases (8.7％).The average number of antibiotic kinds administered on the patients with fungal infection was 4.4,bacteria were 1.4.Ten cases (43.5％) treatment with 1 kind of antibiotic,4 cases (17.4％) with 2,4 cases (17.4％) with 3,5 cases (21.7％) with more than 3.Twenty-two cases (95.7％) cured and 1 case died (4.3％).Conclusions The major species of pathogen causing CRBSIs was coagulase negative staphylococci in PICU.It is critical for clinicians to guard against fungal infection because of prolonged catheter indwelling time and more antibiotics administered before indwelling catheter.It is effective way to prevent the CRBSIs by reasonably using antibiotics and shortening the time of catheter indwelling.Monitoring CRBSIs pathogenic bacteria distribution and drug susceptibility helps reasonable administration of antibiotics in the earlier time.

Objective To analyze how is the elastography of renal tissue correlated to clinical biochemical indexes and pathological changes in patients with chronic kidney disease (CKD), and toexplore the potential of renal elastography to become a new noninvasive method available for the dynamic monitoring of renal disease progression, as well as its efficacy assessment and prognosis evaluation. Methods Patients admitted to the department of nephrology of the First Affiliated Hospital of China Medical University and received renal biopsy from August 2014 to January 2015 were selected. One hundred and thirteen cases of CKD patients, 61 males and 52 females were enrolled, including 23 cases of IgA nephropathy, 39 cases of membranous nephropathy, 15 cases of minimal change nephropathy and 7 cases of focal segmental glomerulosclerosis. The Young modulus of renal cortex and medulla (YMcortex and YMmedul a) were detected by Aix Plorer type full digital color Doppler ultrasound. The correlations between the YMs and clinical biochemical indicators in blood and urine, and the difference of YMs among different pathological changes in patients with CKD were analyzed by statistics. Results The YMcortex and YMmedul a in CKD patients were higher than those in the control group (all P<0.05); and with the progression of CKD, the YMcortex and YMmedul a gradually increased. The YMcortex in CKD G5 patients was higher than that in CKD G1?3 patients (all P<0.05). The YMmedul a in CKD G3?5 patients was higher than that in CKD G1?2 patients (all P<0.05). The YMcortex was correlated with systolic pressure, serum creatinine, cystatin C, serum albumin, serum phosphorus, calcium and phosphorus product, uric acid, intact parathyroid hormone (iPTH), urinary NAG, estimate glomerular filtration rate (eGFR) and hemoglobin (all P<0.05). The YMmedul a was correlated with systolic pressure, serum creatinine, serum albumin, uric acid, iPTH, urine microalbumin (MA), urinary NAG and hemoglobin (all P<0.05). Serum cystatin C (β=0.485, P=0.018) and uric acid (β=0.418, P=0.039) were independently correlated with the YMcortex. Serum creatinine (β=0.380, P=0.019), uric acid (β=0.482, P=0.004) and smoking (β=0.337, P=0.009) were independently correlated with YMmedul a. The YMcortex and YMmedul a in different pathological types were statistically significant (P<0.001, P=0.003). The YMcortex and YMmedul a in patients with membranous nephropathy and IgA nephropathy were higher than those in the patients with minimal change nephropathy (all P<0.05). The YMmedul a in patients with focal segmental glomerulosclerosis was higher than that in the patients with minimal change nephropathy (P<0.05). The YMcortex in the patients with phases Ⅳ and Ⅴ based on the Lee grading system of IgA nephropathy was higher than that in the patients with phases Ⅱ andⅢ (P<0.05). According the Oxford classification for IgA nephropathy, the YMcortex and YMmedul a in the T1 and T2 patients were higher than those in the T0 patients (P<0.05). The YMcortex and YMmedul a showed no statistically significant differences among different stages of membranous nephropathy. Conclusions The YMcortex and YMmedul a are associated with the progress of renal insufficiency, which may become new indicators for determining CKD progression. The renal ultrasound elastography may become a new non?invasive method for early diagnosing CKD, dynamic monitoring disease progression, and assessing efficacy and prognosis.
