Objective To study the efficacy of sacral nerve stimulation combined with tolterodine in patients with female idiopathic overactive bladder (IOAB).Methods A total of 200 female patients diagnosed with IOAB from January 2005 to January 2011 were included in the study,and according to random number table method were divided into treatment group and control group with 100 cases in each.Each group was divided into 3 subgroups according to urinary frequency and urgency,urge incontinence,and both of them together.In the treatment group,patients received percutaneous sacral nerve stimulation and tolterodine 2 mg orally,1 time/d,while in the control group,only given tolterodine 2 mg orally,1 time/d,treatment for 3 months.The voiding diary and urodynamics parameters were observed between the two groups before and after treatment and application of self-rating depression scale (SDS) and self-rating anxiety scale (SAS) to evaluate the psychology of concomitant depression and anxiety score.Results After treatment,the average number of urination,daily average unit urine,the single biggest urine and urine feel capacity (FDV),the maximum capacity of the bladder pressure (MCBC),maximum urinary flow rate (Qmax) in two groups were improved,and the daily average unit urine,single biggest urine and FDV,MCBC,Qmax in treatment group after treatment were higher than those in control group [daily average unit urine:urinary frequency and urgency (248 ± 46) ml/times vs.(150 ± 77) ml/times,urge incontinence (249 ± 69) ml/times vs.(144 ± 81) ml/times,both of them together (247 ± 69) ml/times vs.(170 ± 46) ml/times; the single biggest urine:(320 ± 87) ml/times vs.(212 ± 44) ml/times,(315 ± 65) ml/times vs.(211 ± 56) ml/times,(333 ±59) ml/times vs.(201 ±66) ml/times;FDV:(176 ±64) ml vs.(142 ±44) ml,(190 ±69) ml vs.(142±55) ml,(188 ±60) mlvs.(138 ±49) ml;MCBC:(265 ±46) ml vs.(203 ±50) ml,(288 ±48) ml vs.(197 ± 41)ml,(287 ± 43) ml vs.(189 ± 44) ml],there were significant statistical differences (P ＜ 0.01).The SDS and SAS scores were reduced in two groups after treatment,and the SDS and SAS scores in treatment group after treatment were significantly lower than those in control group [SDS scores:urinary frequency and urgency (33.0 ± 6.2) scores vs.(44.0 ± 5.9) scores,urge incontinence(31.1 ± 6.2) scores vs.(41.6 ± 6.1) scores,both of them together(33.4 ± 7.2) scores vs.(44.5 ± 5.0)scores;SAS scores:(30.3 ± 4.4) scores vs.(41.3 ±4.4) scores,(33.3 ±5.8) scores vs.(42.5 ±6.4) scores,(31.9 ±4.7) scores vs.(43.5 ± 5.6) scores],there were significant statistical differences (P＜ 0.01).Conclusions The combined treatment of tolterodine and sacral nerve stimulation can not only improve the voiding dysfunctions symptoms but also the concomitant depression and anxiety in patients with female IOAB,thus improving the patient's quality of life.

In order to achieve auxiliary timing of ventricular assisting device to automatically track the ECG signals, we designed a set of ECG acquisition circuit in our study for the first time. Then we carried out ECG acquisition, smoothing filter and QRS detection on the LabVIEW. With the QRS signal as a benchmark, the control system immediately triggered ventricular assisting device to trigger the heart to contract for ejection for about 300 ms, and then to assist to make it relax. The practical effects of the experiment proved that ECG acquisition circuit had the feature of strong anti-interference, and control system had no false QRS detection and no false triggering of assist device. This achieves the auxiliary timing which could automatically track the ECG signal.

Objective To observe the clinical efficacy of dye laser combined with Xin'an repair solution in the treating superficial infantile hemangioma(IH). Methods 100 patients with superficial IH were randomly divided into observation group and control group.The observation group received dye laser combined with Xin'an re-pair solution,while the control group was treated only with dye laser.The clinical efficacy and the rate of complica-tions after treatment were compared between the two groups,and the different efficacy between the head neck group and the non head neck group in the observation group was further analyzed. Results The total effective rate of the observation group(90%)was significantly higher than the control group(70%),and the difference was sta-tistically significant(P<0.05).The rate of complications in the observation group was significantly lower than that in the control group(6%vs.32%,P<0.05).In the observation group,the total effective rate of head neck group was better than that the non head neck group(P<0.05). Conclusion Dye laser combined with Xin'an repair so-lution is effective in the treatment of superficial IH,and it can significantly reduce complications.It is evidently ef-fective for head and neck superficial IH.

OBJECTIVE: We hypothesize that the amplitude of low-frequency fluctuations (ALFF) is involved in the altered regional baseline brain function in social anxiety disorder (SAD). The aim of the study was to analyze the altered baseline brain activity in drug-naive adult patients with SAD. METHODS: We investigated spontaneous and baseline brain activities by obtaining the resting-state functional magnetic resonance imaging data of 20 drug-naive adult SAD patients and 19 healthy controls. Voxels were used to analyze the ALFF values using one- and two-sample t-tests. A post-hoc correlation of clinical symptoms was also performed. RESULTS: Our findings show decreased ALFF in the bilateral insula, left medial superior frontal gyrus, left precuneus, left middle temporal gyrus, right middle temporal pole, and left fusiform gyrus of the SAD group. The SAD patients exhibited significantly increased ALFF in the right inferior temporal gyrus, right middle temporal gyrus, bilateral middle occipital gyrus, orbital superior frontal gyrus, right fusiform gyrus, right medial superior frontal gyrus, and left parahippocampal gyrus. Moreover, the Liebowitz Social Anxiety Scale results for the SAD patients were positively correlated with the mean Z values of the right middle occipital and right inferior occipital but showed a negative correlation with the mean Z values of the right superior temporal gyrus and right medial superior frontal gyrus. CONCLUSION: These results of the altered regional baseline brain function in SAD suggest that the regions with abnormal spontaneous activities are involved in the underlying pathophysiology of SAD patients.
