OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Objective To understand the mortality rate and cause of the injury in Hebei province in order to provide scientific theoretical basis for drawing up effective prevention measures.Methods The injury deaths data was collected from 18 surveillance spots in Hebei province during 2004—2005,and the injury was classified with ICD-10 and the corresponding mortality rates were calculated.Results The average injury mortality rate was 54.02/100 000(the age-adjusted rate was 51.62/100 000).It was the 5 th-ranked cause of death.The leading five causes of injury were traffic injury by motor vehicles, traffic injury by non-motor vehicles,suicide,poisoning and fall,which accounted for 23.96%,22.05%,13.10%,11.99%, 5.62%,respectively.The average injury mortality rate in rural(58.48/100 000)was higher than in urban(31.60/100 000)(?~2= 255.82,P

The process of exercise regulating bone metabolism is complicated, which involves a number of signaling pathways. A large number of studies in vitro have indicated that mechanical stress regulates bone metabolism by Wnt, bone morphogenetic protein (BMP), and osteoprotegerin (OPG)/receptor activator of NF-κB ligand (RANKL)/receptor activator of NF-κB (RANK) signaling pathways. Both the in-tensity and frequency of mechanical stress have varing impact on bone tissue and cells. Plenty of studies in vivo also have shown that exer-cise regulates bone metabolism by key factors in bone metabolism signaling pathways. This paper reviewed the effects of exercise on bone metabolism pathways and their mechanisms.

Background Recombinant hirudin variant Ⅲ(rHV3) can effectively prevent galactose-induced human lens epithelial cells LECs injury,but little is known about the molecular mechanism of its action.Objective The present study was to investigate the effects of rHV3 on the expression of apoptosis-related genes in damaged LECs induced by galactose.Methods The rHV3 was extracted by our research group,and the biological activity of rHV3 was identified by titration of thrombase according to Markwardt's method.Human LECs (SRA01/04) were cultured using 125×10-3 mol/L D-galactose+10% FBS+D/F12 medium to establish the damaged human LECs model.rHV3 was added into the medium of the damaged human LECs model.Human LECs were cultured in D/F12 medium containing 10% FBS as normal control.The expression of apoptosis-related genes,such as aldose reductase (AR),bax,bcl2 and p53,in LECs at the mRNA level was detected using RT-PCR.The abundance ratio of target genes was presented with the absorbance (A) of gene mRNA/GAPDH mRNA.Results Compared to the normal control group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were significantly elevated in model group (t=3.90E-06,t=8.44E-04,t=5.15E-08,P＜0.01).However,in the rHV3-treated group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were lower than those of model group (t=5.90E-06,t=1.51E-04,t=3.42E-06,P＜0.01).The bcl2 mRNA/GAPDH mRNA was markedly downregulated in the model group when compared with the normal control group (t=1.86E-05,P＜0.01);while after rHV3 addition,bcl2 mRNA/GAPDH mRNA increased in comparison with the model group (t=8.56E-05,P＜0.01).Conclusion 125×10-3mol/L D-galactose induces the damage and apoptosis of human LECs.rHV3 likely plays a protective function on D-galactose-induced damage of human LECs by inhibiting the polyol pathway and mitochondria-mediated pathway.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

Objective To discuss the effectiveness of anterolateral thigh propeller flaps for treatment of inguinal skin and soft tissue defects.Methods From June,2009 to October,2014,12 patients with inguinal skin and soft tissue defects were treated with anterolateral thigh propeller flaps pedicled with perforator of descending branch of lateral circumflex femoral artery.Of them there were 8 males and 4 females,aged from 22 to 51 years.The left side was involved in 3 cases and right side 9 cases.Defects were caused by traffic accident injury in 5 cases,crash injury of heavy object in 7 cases.There were mere skin and soft tissue in 2 cases,combined with bone fractures,nerves,vessels and muscles injury in 10 cases.The area of defects ranged from 9.0 cm×5.0 cm to 22.0 cm×9.0 cm.During operation,anterolateral thigh propeller flaps ranging from 11.0 cm×7.0 cm to 24.0 cm×1 1.0 cm were used to repair the wounds.Results All flaps and skingrafts survived after operation and the wounds obtained primary healing.After 8-24 months follow-up,all flaps were characterized by soft texture,good color,and satisfactory appearance.According to the Britain's Medical Research Council at 8 months after operation,the sensation of the flaps were recovered to S2 ～ S3+,No obvious scar contracture and chromatosis were observed at donor site.Conclusion Anterolateral thigh propeller flaps pedicled with artery descending branch of lateral circumflex femoral perforator is an ideal choice for the reconstruction for inguinal skin and soft tissue defects.

Objective To explore the application of adaptive statistical iterative reconstruction (ASIR)scanning technique in low dose pediatric cervical CT, especially in reducing the radiation dose for thyroid. Methods We retrospectivly analyzed 140 pediatric cervical CT. 70 cases of group A scaned with ASIR technology and preseting noise index 12 HU in Discovery CT 750 HD (GE Healthcare), and 70 cases of group B scaned with filtered back projection (FBP) technology and preseting noise index 14 HU in VCT 64 (64 Lightspeed VCT, GE Healthcare). The other scan parameters were same in 2 groups. The distribution characteristics of gender and age were completely consistent between groups. The minimum current, the maximum current, the current of thyroid on CT images and CT dose volume index (CTDIvol), scanning length and dose length product (DLP) on dose reports were all recorded for each child. The noise values of CT images were measured. 4 scores standard was used to evaluate the subjective image quality. The data were analyzed with SPSS 13, Kappa method for the test of consistency and t test for the differences of the measured data. Excel was used for mapping. Results The minimum current, the maximum current, the average current, the current for thyroid of the two groups were respectively (26.8 ± 4.2), (43.2 ± 15.4)mA;(35.8±9.6),(41.8±13.6)mA;(34.6±8.6), (41.0±13.2)mA;(36.8±12.3), (44.7±21.0)mA. The CTDIvol, DLP and the scanning length of the two groups were respectively(1.3 ± 0.3), (1.8 ± 0.6)mGy;(29.0 ± 8.3), (40.3 ± 15.6) mGy·cm and(157.5±20.2), (157.6±21.8)cm. The average current, the thyroid current, CTDI and DLP in group A were 15.8%, 17.9%, 27.3%and 28.4%lower than those in group B (t=-5.50—-0.02, P<0.01). The subjective image quality scores of the two doctors were respectively 3.4 ± 0.9, 3.3 ± 1.0, they were highly consistent (Kappa=0.834, P<0.01). The objective image noise of cancellous bone and neck muscles were respectively (32.5 ± 5.3),(32.9 ± 5.1)HU and (9.2 ± 2.3), (9.1 ± 2.0)HU, there were not statistically difference between the two groups (t=-0.47—0.24, P<0.05). Conclusion Compared with FBP, low dose pediatric cervical CT with 30%ASIR could provide dose reduction for thyroid and the whole neck while maintaining diagnostically acceptable images .

Objective To investigate the chest HRCT characteristics of pediatric perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) associated systemic vasculitis. Methods Retrospectively analysis of the clinical and HRCT data of 15 pediatric cases diagnosed as p-ANCA related pneumonia according to the classification and diagnostic criteria of Chapel Hill meeting of 1994 in our hospital were retrospectively analyzed. They were 13 girls and 2 boys. The age range was 1—17 years and the median was about 10 years old, In the 15 patients, 12 were diagnosed as primary MPA, 2 were secondary MPA, 1 was CSS. Two radiologists with 10 years of radiological experience read the CT imaging together. Results 1 of 12 primary MPA were found large opacities and ground glass shades in both sides of lung,especially the posterior parts on CT images with bilateral pleural effusion; 1 case had focal opacities in left lower lobe, around with thickened interlobular septa and pleural effusion; Another 1 case only had focal thickened interstitial in right middle lobe; The other 9 cases showed scattered or diffused ground glass opacity, with thickened pulmonary interstitial and (or) pleura. 1 of the 2 secondary MPA who had hemoptysis showed ground glass opacity on CT images with no thickened septal nodules or pleural effusion. The other one who had renal anomalies and no respiratory symptoms showed subpleural nodules with halo sign in right low lobe. The CSS showed diffused patchy ground glass opacity, consolidation of both lingular lobes, nodules of centri-and peri-lobular, thickened septa near the pleura, obviously thickened bronchial wall, slightly widened bronchial lumen and thickened pleura. Conclusion The classic imaging features of p-ANCA pneumonia on HRCT is the non-specific small pulmonary vessel hemorrhage.

Objective To evaluate of the effect and safety of wearing orthokeratology contact lens or frame glasses for controlling myopia in children. Methods The clinical data from myopia children, who wore orthokeratology contact lens or frame glasses to control myopia, were analyzed retrospectively. Of 219 children (396 eyes), 145 children (277 eyes) wore orthokeratology contact lens, and 74 (119) frame glasses. The changes of diopter, axial length and corneal endothelial cells were observed and compared one year after treatment in the two groups. Results After wearing one year, the diopter and the variation of diopter were significantly less in the children wearing orthokeratology contact lens than those in the children wearing frame glasses ([-3.03±0.89] DS vs [-3.83±1.25] DS, [-0.84±0.90] DS vs [-1.83±0.71] DS; both P<0.05). There was no significant difference in the axial length between the children wearing orthokeratology contact lens and frame glasses. While the extension of axial length was significantly less in the children wearing orthokeratology contact lens than that in the children wearing frame glasses ([0.14±0.15] mm vs [0.40±0.17] mm, P<0.05). No significant differences in the area or density of corneal endothelial cells were found between the children wearing orthokeratology contact lens and frame glasses. Conclusion Wearing orthokeratology contact lens can effectively control myopia in children within one year, and it had no adverse effects on corneal function.
