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.

The clinical value of whole body positron emission tomography/computed tomography (PET/CT) as an imaging tool in diagnosis of ophthalmic tumors was investigated.The retrospective observational case series were performed on the patients with suspected ophthalmic tumors who underwent whole body PET/CT.The golden standard of diagnosis was the final pathological diagnosis or the results of long-term follow-up for patients without surgery/ biopsy.PET/CT findings were compared with the golden standard.The sensitivity,specificity,accuracy and positive likelihood ratio of PET/CT in the detection of ophthalmic tumors were calculated.The clinical application of PET/CT in different types of ophthalmic tumors was evaluated.The results showed that 30 patients (18 males and 12 females) with a mean age of 43.0 years (range 4-63 years) were collected.The mean sizes of orbital tumors and intraocular tumors were 26.8 mm×17.8 mm and 11.2 mm×6.1 mm,respectively.The overall sensitivity,specificity,accuracy and positive likelihood ratio of whole body PET/CT in ophthalmic tumors were 76.5％,71.4％,75.0％ and 2.67,and were 62.5％,100％ and 70.0％ in intraocular tumors,and those were 100％,60.0％ and 84.6％ in orbital tumors,respectively.PET/CT findings were applied to help make appropriate treatment options in 27 out of 30 patients (90.0％),and 12 (40.0％) patients changed the treatment strategy.False negative results in 4 cases and false positive results in 2 cases were observed in this series.It was suggested that PET/CT was an effective imaging modality in detecting,diagnosing and developing therapeutic schedule for patients with ophthalmic tumors.It was more sensitive and accurate for detecting orbital tumors than for detecting intraocular tumors.

The aim of this study was to design a simple, economic, with high Common Mode Rejection Ratio (CMRR), preamplifier and multi-channel masticatory muscle surface electromyography (sEMG) signal acquisition system assisting to diagnose temporomandibular disorders (TMD). We used the USB interface technology in the EMG data with the aid of the windows to operate system and graphical interface. Eight patients with TMD and eight controls were analyzed separately using this system. In this system, we analyzed sEMG by an optional combination of time domain, frequency domain, time-frequency, several spectral analysis, wavelets and other special algorithms under multi-parameter. Multi-channel sEMG System of Masticatory Muscles is a simple, economic system. It has high sensitivity and specificity. The sEMG signals were changed in patients with TMD. The system would pave the way for diagnosis TMD and help us to assess the treatment effect. A novel and objective method is provided for diagnosis and treatment of oral-maxillofacial disease and functional reconstruction.

Methods Fifteen healthy New Zealand white rabbits were included in this study.0.2 mL tumor tissue suspensions were injected into the rabbits’posterior limb.14 days later,all rabbits were underwent conventional MRI examination.PET were performed to all the tumors under the guidance of MRI in the next day of the examination.T2 WI was used as guidance and monitoring means.MR com-patible puncture needle with lateral hole was stabed into the lesion center,and inj ected anhydrous ethanol according to the volume of tumors’diameter (1 mL/cm )slowly.the tumors signal characteristics,morphological feature and pathological feature were ob-served pre and post-operation.Results All of the 1 5 rabbits were established soft tissue tumor model successfully;the success rate is 100%.The tumors were oval or round,3-4 cm in diam.MRI scanning showed low signal on T1 WI and high signal on T2 WI be-fore PEI.PEI was performed to all the tumors under the guidance of MR successfully with 3.5 mL ethanol injected into the tumors in average.T2 WI could monitor the ethanol in dispersion and distribution within the tumors clearly.Histologically,tumors were composed of large,uniform,oval/round cells arranged in solid nests which was intensive in the periphery of tumors.Necrosis tissue was apparent in the center of the tumors.10 days after operation,most tissue in the periphery of tumors was coagulative necrosis , only a few tumor cells left.Ranges of necrosis in the tumors center were obviously increased compared with pre-operation.Conclusion Rabbit VX2 tumor of soft tissue model is suitable for the therapeutic evaluation of tumor .It is an animal model which has the characteristic of simple to operate and high rate of suc-cessful.MR T2 WI can monitor the ethanol in dispersion and distribution within the tumors clearly.It is a good guidance and monitoring imaging method of tumor ablation.

ObjectiveTo understand the prevalence of maternal anemia and iron deficiency during the second and third trimesters and their relationship with adverse pregnant outcomes.MethodsData of 3 262 gravidas, who received prenatal care and delivered at Drum Tower Hospital from October 1, 2013 to October 31, 2014, were retrospectively collected and analyzed. Blood routine test was performed for all subjects both at the second (20-22 weeks) and third trimesters (38 weeks of gestation or before delivery) using automatic blood analyzer. Moreover, serum ferritin level was determined at the second trimester with microparticle chemiluminescence immunoassay. Treatment was offered to those diagnosed as iron deficiency anemia or severe iron deficiency, and the adverse pregnancy outcomes were analyzed.Chi-square test and TrendChi-square test were performed for statistics.Results(1) Out of the 3 262 women, 601 (18.42%) were diagnosed as anemia at second trimester, among which 444 (73.88%) recovered at the third trimester after proper treatment. However, there were 285 (8.74%) new-onset anemia pregnancies at last trimester. Thus, the total prevalence of anemia in pregnancy was 27.16% (886/3 262). (2) The mean serum ferritin level at the second trimester was (29.40± 30.12) ng/ml, and 1 565 (47.98%) were diagnosed as iron deficiency at the same period. (3) During the mid-term pregnancies, 345 iron deficiency anemic women were identified, which accounted for 57.40% of all anemic cases in this study. Two hundred and fifty out of the 345 women were cured at the third trimester. However, another 206 new-onset iron deficiency anemic pregnancies were identified at the third trimester. For iron deficiency anemia both at mid- and late-term pregnancy, the prevalence was 16.89% (551/3 262), which accounted for 62.19% (551/886) of all anemic patients. (4) There were more women with microcytic hypochromic anemia in the late-trimester than in the mid-trimester [19.93%(60/301) vs 4.93% (17/345),χ2=34.478,P<0.01]. (5) Among women with serum ferritin≥30,≥20- <30,≥10- <20- <10 ng/ml, the prevalence of mild anemia in mid-trimester was 13.33%(142/1 065), 14.40%(91/632), 14.71%(130/884) and 24.82%(169/681), the prevalence of new-onset anemia in the third trimester was 3.94%(42/1 065), 5.85%(37/632), 12.78%(113/884), and 13.66%(93/681) respectively. The lower the serum ferritin level, the higher the prevalence of anemia in the mid-trimester (χ2trend=30.697,P<0.01) and the new-onset anemia in the last trimester (χ2trend=69.871,P<0.01). (6) The incidence of postpartum hemorrhage in pregnancies with serum ferritin level at≥10 but <20 ng/ml was significantly higher than those normal one [20.39%(52/255) vs 11.92%(75/629),χ2=10.577,P<0.01]. Neither serum ferritin level nor anemia was associated with other adverse pregnancy outcomes.ConclusionsThe incidences of anemia and iron deficiency remain at a high level at the second and third trimesters. The lower the serum ferritin level at mid-trimester, the higher the incidence of anemia.

Aim Toresearchthemolecularmecha-nisms of DADS-induced apoptosis in human leukemia K562cells.Methods Cellviabilitywasmeasuredby MTT. Levels of DADS-induced ROS were measured by 2ˊ, 7ˊ-dichlorofluorescein diacetate ( DCFH-DA) fluo-rescence. DADS-induced mRNA levels of components of the NADPH oxidase were detected by Real-time PCR. The combination of protein Rac2 and p67phox was measured by immunoprecipitation assays. Flow cy-tometry methods were used to determine the percentage of apoptosis cells. DADS-induced Rac2 levels were measuredbyWesternblot.Results TheDADS-trea-ted K562 cells showed a dose-and time-dependent de-crease in cell viability and proliferation. There was sig-nificant up-regulation of the mRNA level of components of the NADPH oxidase complex in K562 cells after treatment with 6 mg·L-1 DADS for 6 h. Western blot results revealed that, compared with the control group, there was a significant up-regulation of Rac2 protein in K562 cells treated with 5. 0 and 10. 0 mg·L-1 DADS for 24h. And Rac2 combined with p67phox in DADS-induced apoptosis in K562 cells. PMA markedly in-creased the percentage of apoptotic cells, and DPI re-duced the percentage of apoptotic cells in DADS-in-duced K562 cells. Levels of DADS-induced ROS, also showed enhancement when exposed in PMA, but there was no DADS-induced ROS production evident when exposed in DPI in DADS induced K562 cells. Conclu-sions TheseresultsindicatethatNADPHoxidaseis the main source of DADS-induced ROS production. Diallyl disulfide induces apoptosis in human leukemia K562 cells through activation of NADPH oxidase.

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.

OBJECTIVE:To investigate the preventive and therapeutic effect of Shuganning injection on alcoholic liver fibrosis (ALF) in model rats,and provide experimental basis for its clinical application for alcoholic liver disease. METHODS:50 rats were enrolled and intraperitoneally given mixed liquid of 60% alcohol-corn oil-pyrazole to reduce ALF model. Another 10 rats were enrolled and intraperitoneally given normal saline,as normal control group. After 16 weeks,survived model rats(n=40)were ran-domly divided into model group,positive control group(Anluo huaxian pill 0.75 g/kg,ig),Shuganning injection high-dose,medi-um-dose,low-dose groups(4.8,2.4,1.2 mL/kg,ip),8 in each group. Normal control group and model group were intraperitone-ally injected equal volume of normal saline (5 mL/kg),administration groups were given relevant medicines,once a day,for 8 weeks;and modeling was contiuously conducted at the same time. After administration,body mass of rats was weighed,and the levels of liver function indexes [aspartate aminotransferase(AST),alanine aminotransferase(ALT)] and liver fibrosis indexes [hyal-uronic acid(HA),laminin(LN),type Ⅲ procollagen(PⅢNP),type Ⅳ collagen(Ⅳ-C)] in serum of rats were detected. Liver index of rats was determined and pathological changes of liver tissue were observed. RESULTS:Compared with normal control group,body mass of rats in model group was significantly decreased(P<0.05);liver index,and liver function index,liver fibro-sis index levels in serum were significantly increased (P<0.05 or P<0.01). Liver tissue showed steatosis,hepatocyte vacuoliza-tion,a large number of fibrous tissue deposition around portal areas and other pathological changes. Compared with model group,above-mentioned changes were improved significantly in administration groups (P<0.05 or P<0.01). CONCLUSIONS:Shugan-ning injection can obviously improve liver tissue damage of model rats with ALF,showing certain preventive and therapeutic effect on alcoholic liver disease.
