[Objective]To observe the effect of electroacupuncture at Baliao on a chronic pelvic pain syndrome. [Method] Choice in March 2014 to January 2016 in our hospital clinic of 103 patients with chronic pelvic pain syndrome, according to the order of the patient, with reference to random number table, divided the patients into the treatment group and control group, the treatment group patients with 50 cases, control group 53 cases. Treatment group patients given cuppingBaliaopoint treatment, control group patients give Tensorosin hydrochloride sustained-release capsules, one time a day, 0.2 mg each time, after meals, a total of two groups of patients in the treatment of 4 weeks, observe two groups of patients with prostatic inflammation at the end of the treatment of NIH-CPSI score, clinical curative effect and clinical relapse over 3 months of treatment. [Results] (1)After the treatment, two groups of patients with pain or discomfort, micturition abnormal, the quality of life score and NIH-CPSI total score were improved significantly, the difference was statistically significant;Comparison between the two ways, found that the treatment group patients in pain or discomfort, the quality of life, and the NIH-CPSI total integral comparison, obviously improved compared with control group, difference had statistical significance( P<0.05), but the two groups of patients with abnormal micturition, had no statistically significant difference(P>0.05); (2) the treatment group patients clinical total effective rate was 85.4%, the control group was 74.5%, two groups of clinical curative effect comparison, had no statistically significant difference( P>0.05); (3) 3 months after treatment, the treatment group patients there were 7 cases of recurrence of patients with recurrence(17.1%), the control group 14 cases of recurrence of patients with recurrence(36.8%), compared two groups of clinical relapse rate, difference had statistical significance( P<0.05), recurrence of clinical treatment group was obviously less than the control group. [Conclusion] Take electroacupuncture at Baliao point can obviously improve clinical symptoms in patients with the disease, improve patient's quality of life and reduce recurrence forward, but in the future it's a worthy research to adopt a more scientific research design, including evaluationBaliaopoint for the clinical curative effect of treatment of the disease.

Objective To investigate the differential expression of microRNAs(miRNAs) in transplanted kidney undergoing chronic rejection by the technique of RNA microarray.Methods Four biopsy specimens from transplanted kidney undergoing chronic rejection were harvested as test group(CR),and 3 biopsy specimens were obtained from normal renal cortex as normal control group(NC).Total RNA of each sample was extracted using Trizol reagent.miRNAs were isolated and differential expression of miRNAs were screened by miRNA array analysis.The results of miRNA array were validated by RT-PCR.The quantity and quality of all the RNA samples were checked by gel electrophoresis and absorbance at A260/280,respectively.Results It was confirmed that the isolated RNA was of appropriate quality.The results of miRNA array analysis showed that there were 63 differential expression miRNAs in CR group,of which 35 were up-regulated and 28 down-regulated.There were 9 differential expression miRNAs which distributed in 3 gene clusters: 14q32.31,22q11.21 and xq27.3.The miRNAs hsa-miR-637,hsa-miR-648 and hsa-miR-516-5p were randomly selected for relative quantification by real-time PCR.It was showed that the expression ratios of hsa-miR-637,hsa-miR-648 and hsa-miR-516-5p in AR/NC,when detected by RT-PCR,were 0.034,2.670 and 7.846,while the ratios were 0.035,2.660 and 7.857 when analyzed by miRNAs array.The results from two methods were not significantly different,so the method of miRNAs array was reliable.Conclusions It is notable that the differential expression of miRNAs existed in the transplanted kidney undergoing chronic rejection.miRNAs might be helpful in protecting the patients undergoing kidney transplantation against chronic rejection.

Objective To evaluate the value of diffusion-weighted imaging (DWI)in diagnosing the acute centrum ovale infarction, and also to investigate the pathogenesis of the infarction. Methods All 58 patients underwent conventional MRI and DWI scanning after symptoms’ onset. DWI findings were compared to the findings of T_1WI and T_2WI. Results The sensitivity and specificity in diagnosing the ischemia stroke were 96.4% and 98.8% within 7 days after onset. Of all the cases, 62.1% were associated with the cerebral large-vessel disease and emboligenic heart disease. Only 36.2% had a classic lacunar syndrome but 69.0% had more frequently an abrupt onset of symptoms. Conclusion DWI is of high accuracy for diagnosing centrum ovale infarction and detecting early infarction lesions which are difficult to be displayed in conventional MRI, and very helpful in differentiating the acute from non-acute lesions; symptomatic centrum ovale infarction is suggested to be associated with large-vessel and heart disease which should be distinguished from the lacunar infarcts.

Objective To evaluate the manifestations and diagnostic value of CT enterography (CTE) in primary intestinal T-cell lymphoma (PITCL).Methods Eighteen patients with PITCL confirmed by pathology were reviewed retrospec tively.The characteristics of lesion site,amount of foci,pattern and degree of contrast enhancement,lymphadenopathy,involvement of other organs and complications were recorded.Results In all of the 18 patients with PITCL,multiple lesions were seen in 13 cases (13/18,72.22％),and solitary involvement was seen in 5 cases (5/18,27.78％).Twelve ca ses were located at jejunum/ileum,3 of them were also involved in the colon.Five cases were located only in the colon,and 1 in the duodenum.Six cases were complicated with intestinal perforation.The patients were categorized into 6 types according to the CT manifestation:infiltration type (n=7),diffuse jejunum mucosa ileum metaplasia type (n =3),luminal aneurismal dilatation type (n =3),polypoid mass type (n =2),mesentery type (n=1),mixed type (n =2).Conclusion CTE can clearly display the imaging of PITCL and it has high value for the diagnosis of PITCL.

Objective To investigate the correlation between the paired inspiratory and expiratory quantitative CT and pulmonary function tests (PFTs) in patients with chronic obstructive pulmonary disease (COPD).Methods A total of 84 patients with COPD were enrolled.For each patient,CT scan was performed in deep inspiration and expiration.Using automatic post-processing software,a three-dimension quantitative measurement was employed to assess the CT parameters of emphysema and air trapping.The correlation between CT and PFT was evaluated by the Spearman rank correlation test and multivariate linear regression analysis.Results The percent 1 [Perc1,(-984.28 ± 17.93) HU] and percent 15 [Perc15,(-948.35 ± 22.26) HU] from the CT parameters of emphysema were positively correlated with the forced expiratory volume in 1 second predicted (FEV1％,48.69 ± 23,47),the ratio of forced expiratory volume in 1 second over forced vital capacity [FEV1/FVC,(45.89 ± 15.36)％,r =0.454.-0.67,P ＜0.01],was negatively correlated with the ratio of residual volume to total]ung capacity [RV/TLC,(61.32 ±14.48)％].The other CT parameters of emphysema index (EI) and the parameters of air trapping,the change in relative lung volume with attenuation values from-860 to-950 HU [RVC-860--950,(17.66 ±22.36)％],the expiration to inspiration ratio of mean lung density (MLDex/in,0.93 ± 0.06),the expiration to inspiration ratio of lung volume(LVex/in,0.71 ± 0.14) had negative correlations with logFEV1 ％,FEV1/FVC (r=-0.48--0.69,P＜0.01) and positive correlations with RV/TLC (r =0.41-0.66,P ＜0.01).The further univariate linear regressions showed that EI,Perc1,Pere15,RVC-860--950,MLDex/in,LVex/in were correlated with the parameters of PFTs (R square values of the regression equation,ranged from 0.27 to 0.66,P ＜ 0.01).After the pairwise combinations of the parameters of emphysema and air trapping,multivariate stepwise regressions showed better R square values from 0.66 to 0.85.Conclusions CT parameters of emphysema and air trapping can reflect pulmonary function in COPD patients.The combinations of the two types of CT parameters are more correlated with the PFTs parameters.

Objective To evaluate the relationship between the lung volume (LV) in inspiration and expiration,pulmonary function tests(PFT),and other CT measurements of emphysema index (EI) and mean lung density (MLD) in patients with chronic obstructive pulmonary disease (COPD).Methods Seventy-six patients with COPD were included.Three-dimension analysis was performed to obtain the following CT parameters on the inspiratory and expiratory phases:EI,MLD,LV.The ratios and differencesof MLD and LV between the two phases were calculated(ΔMLD,ΔLV,MLDex/in,LVexin).Not only the linear correlations between the lung volume parameters and PFT but also the correlations of lung volume parameters with the other CT parameters were tested by the Spearman rank correlation test and multivariant step wise regression.Results LVex/in had negative correlations with forced expiratory volume in 1 second ％ predicted [FEV1 ％,(54.32 ± 7.11)] and the ratio of forced expiratory volume in 1 second to forced vital capacity [FEV1/FVC,(49.12 ±8.01)％] (r =-0.69,-0.56,P ＜0.01),but it had the positive correlation with the ratio of residual volume to total lung capacity [RV/TLC,(58.03 ± 8.55) ％,Spearman coefficients 0.66,P ＜ 0.01].LV/exin (0.67 ± 0.12) was positively correlated with MLDex/in (0.89 ± 0.04,r =0.88,P ＜0.01).The further multivariate step wise regression denonstrated that EI,LV and MLD could introduce a regression equation with R2 =0.77 and 0.73,respectively (P ＜ 0.01).Conclusions There is an association between LVex/in and the parameters of routine PFT,which can reflect the collapsibility of lung.Moreover,LVex/in can be considered to be equivalent to MLDex/in.Taking into account the impact of scanning parameters on MLDex/in,LVex/in may play a complementary role in the assessment of pulmonary function.

OBJECTIVETo analyze the drug-sensitivity-related genes to anti-tumor drugs navalbine (NVB) and docetaxel (Doc) in four SCLC and six NSCLC cell lines.

METHODSThe sensitivity of 4 SCLC lines and 6 NSCLC lines to NVB and to Doc was determined with MTT test. The expression of 1291 anti-tumor drug sensitivity-related genes in the 10 cell lines was assayed by cDNA macroarray technique, and cluster analysis was performed to find the relationship between the results obtained by the above mentioned two measurements.

RESULTS(1) The anti-tumor effect of NVB on the 10 cell lines was apparently better than that of Doc. (2) The drug sensitivity-related genes in these 10 cell lines showed a more close positive correlation with Doc than that with NVB, whereas more genes showed negative correlation with NVB than that with Doc. But in 6 NSCLC cell lines, more genes showed the same positive or negative correlation with the two drugs. (3) 51 genes in the 10 cell lines showed correlation with Doc or NVB. 13 of them had negative correlation with Doc, 11 of them showed positive correlation. 24 of them showed negative correlation with NVB, 3 of them showed positive correlation. 67 genes in 6 NSCLC cell lines showed a correlation with sensitivity to Doc or NVB, among them 34 had negative correlation with Doc, 4 had positive correlation. 25 genes had negative correlation with NVB, 4 had positive correlation. (4) Rab 1, Rab 3, Rho B, Rho C, Rac 1, Rac 2, Gho GDI beta, CD44, integrin alpha5, integrin alpha6, integrin beta5, vinculin showed to be cytoskeleton-related genes differently expressing in SCLC or NSCLC cell lines.

CONCLUSIONThere is obvious difference in the drug sensitivity-related genes to NVB or Doc between SCLC and NSCLC cell lines.

OBJECTIVETo investigate the effects of oral administration of low-dose propranolol on heart rate variability (HRV), acceleration capacity (AC), deceleration capacity (DC), and cardiac conduction in the treatment of infantile hemangioma.

METHODSA total of 118 infants with hemangioma (≤1 year) were enrolled, and 24-hour ambulatory electrocardiography was performed before oral administration of low-dose propranolol and after one month of administration. The changes in time-domain indices [standard deviation of all normal sinus RR intervals (SDNN), standard deviation of all mean 5-minute RR intervals (SDANN), root mean squared successive difference (RMSSD), and percentage of successive normal sinus RR intervals >50 ms (PNN50)] and frequency-domain indices [low frequency (LF) and high frequency (HF)] for HRV, AC, and DC were observed, as well as abnormalities in cardiac conduction and other aspects after administration of propranolol.

RESULTSAfter administration of propranolol, the infants had significantly increased SDNN, RMSSD, LF, HF, and PNN50 (P<0.01), and significantly reduced AC, mean heart rate (HR) and minimum HR (P<0.01). The 24-hour ambulatory electrocardiographic findings showed a nonsignificantly higher abnormal rate after administration of propranolol.

CONCLUSIONSIn the treatment of infantile hemangioma, propranolol can inhibit the activity of sympathetic nerve and block cardiac conduction, but without any serious adverse effect.
