Objective To understand the guidance significance of sputum smear on the sputum culture by comparing the micro-scopic detection results of sputum smear with the sputum culture results in 227 cases.Methods 227 cases of sputum specimen were collected for observing the character and smear staining by microscopy.These specimens were divided into the class A,B,C and D according to the standards and simultaneously conducted the culture.The relationship between smear and culture was analyzed.Reˉ sults Among 227 cases of sputum specimen,158 cases were qualified and accounted for 69.60%,and 69 cases were unqualified and accounted for 30.40%.Potential pathogens were detected in 128 cases,the positive detection rate was 56.39%,the positive detec-tion rate of qualified sputum specimens was 70.39% and which of unqualified sputum specimens was 28.00%.The coincidence rate of qualified sputum specimen smear results and the culture results was 72.78%.The positive rate of cytophagic bacteria in the qual-ified sputum specimens was 11.72%,in which 14 cases of cytophagic bacteria were the qualified class A sputum specimens with the positive rate of 16.67% and 5 cases of cytophagic bacteria were the class B sputum specimens with the positive rate of 6.76 %. Conclusion The sputum smear microscopic detection can provide the important information for the diagnosis and treatment of re-spiratory infections and the sputum smear has the important guiding significance for sputum culture.

The clinical application of GlucoWatch used in 32 Chinese diabetic patients was evaluated to determine its value in following blood glucose trends and track patterns and to know the compliance of patient. The results confirmed the accuracy of GlucoWatch and showed that it could follow blood glucose trends and track patterns. The skin irritation was mild and most subjects thought that blood glucose monitoring by GlucoWatch could reduce the pain caused by traditional methods.

Objective To observe the glucose profile in type 2 diabetic gastroparesis.Methods 31 patients diagnosed with type 2 diabetes were enrolled into this study for measurement of gastric emptying of solids and continuous glucose monitoring to observe blood glucose 1evels for 72 hours on a balanced diet;the results were compared with 7 subjects with norinal glucose regulation.Results 58.1%of 31 type 2 diabetic patients were found to have delayed gastric emptying of solids.The average glucose level was lower after breakfast[(7.82±1.42)mmol/L vs(9.35±2.28)mmol/L,P<0.01]in the patients with gastroparesis than in those without.Maximal blood glucose level after breakfast[(10.21±2.17)mmol/L vs (12.24±2.82)mmol/L,P<0.01]was lower in the patients with gastroparesis but it reached the peak at a similar time.Two hour AUC was also lower after breakfast in the patients with gastroparesis[(877.62±Post-prandial glucose levelin type 2 diabetic patients with gastroparesis tends to be lower than those without.

Intravoxel incoherent motion (IVIM) can distinguish the molecular diffusion from the pseudo-diffusion of microcircular perfusion to obtain true diffusion coefficient (D),pseudo-diffusion coefficient (D*) and perfusion fraction (f),which are sensitive to detect alterations in cellularity and microcirculation perfusion.IVIM can also evaluate early therapeutic effects,optimize treatment plan,predict prognoses,and provide information for choosing appropriate treatment methods.In this paper,the principle of IVIM and its application in tumor response evaluation were reviewed.

ObjectiveTo summarize the research and manufacturing ideas of precise positioning instrument and its feasibility and safety in the minimally invasive percutaneous nephrolithotripsy.Methods The precise positioning instrument was preliminarily made by integrating ruler with protractor.Fifty cases of kidney stones or upper ureteral stones were recruited in the study.There were 32 males and 18 females with mean age of 47 years (21 -75 years).Of them,6 cases had open surgery history and 31 cases had different degrees of hydronephrosis.The distance from the mid-point of renal pelvis to the plane of the dorsal surface and the distance from the incident point of the mid-point of pelvis on the dorsal surface to spinous process were measured by ruler on the preoperative CT images.According to the measured results,the point,angle,direction and depth of needle were calculated by geometric formula,and then fix position puncture and percutaneous puncture channel expansion were completed by precise positioning instrument and calibrated by Carm X-ray machine.ResultsThe puncture channels were established successfully in all of the 50 cases.Forty-six cases were punctured successfully by just one try,and the success rate of one puncture only was 92.0％.C-arm was used in none of the cases during the channel establishing process.Each patient was Xrayed 1 -3 times,and the average was 1.4 times.Targeting deflection or renal pelvis injury occurred in none of these cases.ConclusionThe application of the homemade precise positioning instrument is a safe and quick method for the establishment of puncture channel during percutaneous nephrolithotripsy,meanwhile the surgeons can reduce the exposure to radiation.

Objective To investigate the effects of D-limonene on the proliferation and ras P21 expression in human bladder carcinoma EJ cell.Methods The cell proliferation was measured by XTT assay.The expression of ras mRNA was detected by real-time PCR,and the expression of its protein product was analyzed by Western Blot.Results The proliferation of EJ cell was inhibited by exposure to 2 mmol/L and 4 mmol/L D-limonene for 48h.The optical density (A) was 0.801±0.016 and 0.148±0.008,respectively.There were significant differences between the experimental groups and the control group (1.2181±0.031,P<0.05).The expressions of ras P21 and its protein product of EJ cell were decreased obviously when exposure to 1 mmol/L of D-limonene for 48h.The expres-sions were significantly different compared with the control group(P<0.05).Conclusions D-limo-nene could inhibit human bladder carcinoma EJ cell proliferation,which is in a dose-dependant man-ner.In a lower dose (<1 mmol/L),D-limonene can decrease the expression of ras mRNA and its protein product.

Purpose To investigate the influence of the region of interest (ROI) selection on the repeatability of 64 slice spiral CT perfusion parameters for the peripheral lung cancer.Materials and Methods The 64 slice spiral CT perfusion images of thirty-seven patients with peripheral lung cancer were retrospectively analyzed.The perfusion parameters including blood flow (BF),blood volume (BV),Patlak blood volume (PBV),permeability surface area product (PS),and mean transit time (MTT) were obtained by using three ROI selection methods including maximum area of ROI (ROIm),round of ROI (ROIr),and volume of ROI (ROLv),and these parameters were measured by two observers repeatedly.The repeatability and reliability of the values of these perfusion parameters by using different ROI methods or measured by different observer were determined.Results The perfusion parameters derived from three ROIs all had a excellent intraobserver and interobserver agreement (ICC＞0.75).Besides,the values of the perfusion parameters by using different ROI methods had no significant difference (P＞0.05),but the data obtained by ROIm and ROIv were more stable than that obtained by ROIr.Conclusion The repeatability of the perfusion parameters obtained from above three ROIs is excellent,but ROIm and ROIv may be more suitable than ROIr to assess vascular perfusion of peripheral lung cancer.

OBJECTIVE: Our goal was to find whether inreversible function damage of saccule was exist and correlated in Meniere's patients with different audition. METHOD: Senenty-nine patients with unilateral Meniere's disease, who visited the Dizziness Diagnosis and Treatment Centre of the Second Military Medical University from January to July in 2015 were included. They were grouped as slightly audition damage group (41 cases), mildly-severely audition damage group(38 cases). Meanwhile 20 normal controls underwent the research. The cervical vestibular evoked myogenic potentials were conducted in symptom free period. RESULT: There was no significant difference of the C-VEMP inducing rate between slightly audition damage group and normal control group. While a statistically difference showed between mildly-severely audition damage group and normal control group or slightly audition damage group. P1, N1 latency had no statistically difference between three groups. The P1-N1 amplitude and asymmetric ratio had no difference between slightly audition damage group and normal control group, but had a statistically difference between mildly-severely audition damage group and slightly audition damage group, normal control group. CONCLUSION The function of saccule in Meniere's patients decreased with the aggravation of audition damage.
