OBJECTIVETo explore the clinical effect of Shugan Jieyu Capsules (SJC) on type III B prostatitis complicated by sexual dysfunction.

METHODSA total of 98 patients with type III B prostatitis complicated by sexual dysfunction were equally randomized to a control and a trial group, the former treated with the combination of biofeedback/electrical stimulation and the α-blocker Tamsulosin Hydrochloride, and the latter with oral SJC in addition, both for 8 weeks. Before and after treatment, the severity of the symptoms was determined with NIH-CPSI, the patients'sexual function evaluated with CIPE-5 and IIEF-5, and their anxiety, depression and other psychological problems assessed with Hamilton Anxiety Scale (HAMA) and Hamilton Depression Rating Scale ( HAMD). The results were subjected to statistical analysis and compared between the two groups.

RESULTSStatistically significant differences were found between the control and trial groups in the NIH-CPSI score (26.31 ± 7.91 vs 18.84 ± 6.63, P < 0.01), CIPE-5 premature ejaculation score (10. 41 ± 3.03 vs 14.37 ± 2.35, P < 0.05), IIEF-5 score (10.29 ± 3.97 vs 14.69 ± 4.19, P < 0.05), HAMA score (24.31 ± 1.78 vs 13.41 ± 4.21, P < 0.01), and HAMD score (25.24 ± 2.83 vs 14.49 ± 4.44, P < 0.01).

CONCLUSIONSJC can effectively relieve anxiety, depression and other psychological problems in type III B prostatitis patients with sexual dysfunction and improve their clinical symptoms as well.

Objective To assess the removal efficiency of bacteria by water purifiers using different purifying materials. Methods The bacterial removal effectiveness of 7 types of commercially available water purifiers was tested using the National Standard Methods. Results Apart from one type using a single activated-carbon filtering material, the bacteria removal effectiveness of the other 6 types of water purifiers met the requirements of water purification device according to the rated treated-water-capacity conditions. Conclusion The removal efficiency of bacteria by water purifiers made from different filtering materials was different. Bacteria elimination effectiveness of a single-filtering material was lower and it is inversely proportional to its water-treating capacity. Water purifiers using multiple-purifying materials gave better removal efficiency of bacteria.

Objective To evaluate the diagnostic value of transbronchial lung biopsy (TBLB) via bronchoscope for lung diffuse lesions and peripheral pulmonary lesions. Methods The results of TBLB were retrospectively analyzed from 256 diagnoses of unknown patients with lung diffuse lesions or peripheral lung lesions. Results Eighty-nine final diagnosis cases via TBLB only once, the diagnostic rate of double lung diffuse lesions was the highest, [51.06% (24/47)], local non-nodule lesions, nodule lesions, cavity lesions were 33.33%(23/69), 29.91%(35/117), and 28.57%(4/14), respectively. Among 24 diagnostic cases of double lung diffuse lesions, there were 6 cases of pneumonia of pulmonary tuberculosis, 9 cases of lung carcinoma, 7 cases of adenecarcinoma; 6 cases of pneumonia, 2 cases of fungous infection, and 1 case of lung hemosiderusis. The diagnostic yield about 58 cases of local lesions was low, among which non-nodule lesions accounted for 33.33% and nodule lesions accounted for 29.91%. In 89 cases of peripheral lung lesions with histological diagnosis, lung carcinoma and pulmonary tuberculosis were frequent diseases, which accounted for 86.52%. Conclusion TBLB is a reliable, safe, effective and repeatable operation method in diagnosis of lung diffuse lesions and peripheral pulmonary lesions.

BackgroundHypoxia-inducible factor-1 α (HIF-1α) specific double-stranded RNA ( dsRNA ) mediated by liposome inhibit reinal neovascularization in mice at dose-dependent manner. ObjectiveThe present study was to investigate the inhibitory effect of dsRNA targeting HIF-1α on retinal neovascularization in mice.MethodsModels of oxygen-induced retinal neovascularization were set up in C57BL/6J mouse through exposure of postnatal day 7 ( P7 ) to (75±3) ％ oxygen for 5 days.Fluorescein conjugated Dextran angiography of retinal vascular was performed to identify the retinal neovascularization.The 8 mice of the normal group were raised in the room air.Fifty-one P7 mice exposed to(75±3)％ oxygen for 5 days and then returned to the room air and assigned to control group ( 3 mice),empty vector group( 3 mice) and gene therapy group (45 mice),and the latter were medially divided to 9 groups randomly according to dose-ratio ( liposomes ∶ plasmid).The pSilencer 2.1-U6 hygro was injected in the model mice of empty vector group,and different dose-ratios of pSilencer2.1-U6 hygro-HIF-1α dsRNA were injected respectively in the model mice of various gene therapy groups.Fluorescein conjugated Dextran angiography of retinal vascular was performed to observe the morphology of new blood vessels,and retinal slides were prepared to score the numbers of nuclei extending beyond the inner limiting membrane( ILM ),and expression of vascular endothelial growth factor(VEGF) was detected in the retina by immunohistochemistry.Results The retinal blood vessels of the normal group formed a fined radial branching pattern.The retinal vascular patterns in the control group and the empty vector group were characterized by decreased central perfusion in both the superficial and the deep layers.The abundant vessels were distorted and irregular in the control group and empty vector group,and the obstructed capillary and lots of neovascular tufts were seen.The retinal neovascularization and non-perfusion distraction in the every gene therapy group were reduced markedly with the most severe appearance in 1 ∶ 1 ( liposomes ∶ plasmid) dose-ratio group.Few vascular endothelial cell nucleus extending beyond the ILM were found in the normal group;while a large number of vascular endothelial cell nucleus were showed in the control group and empty vector group with the occurring rate 100％.Statistically,no significant difference was seen in the number of nuclei extending beyond the ILM between the control group and the empty vector group(11.57±5.85 vs 11.53±6.15),however,that in 1∶1 (liposomes∶plasmid) group was reduced markedly ( 2.17 ± 4.23 ) ( P ＜ 0.01 ).Immunohistochemistry revealed that VEGF was faintly expressed in the normal group but strongly expressed in the control group and the gene therapy group.VEGF expressions of various gene therapy groups were weaker than ones of the control group and the empty vector group.ConclusionsRetinal neovascularization can be efficiently inhibited by intravitreal injection of the pSilencer2.1-U6 hygro-HIF-1α dsRNA mediated by liposome.Proportion of 1 ∶ 1 (liposomes ∶ plasmid)has a maximized efficiency.

Objective To investigate the effect and mechanism of HPV16-E7 gene specific CRISPR/Cas (clustered regularly interspaced short palindromic repeat/CRISPR associated system) on the cell apoptosis and proliferation of human cervical cancer SiHa cell line.Methods HPV16 positive cervical cancer SiHa cells and HPV16 negative human embryonic kidney HEK293 cells were cultured and each of the cells were divided into 3 groups respectively in the experiment:the control group was untreated,the C9 group was transfected only with Cas9 plasmid,and the Cri group was cotransfected with guide RNA (gRNA) plasmid and Cas9 plasmid (1∶3).T-7endonuclease Ⅰ assay was used to detect double strand break (DSB) formation in SiHa cells.The apoptosis rates of SiHa and HEK293 cells were detected by flow cytometry (FCM).CCK-8 was used to evaluate the proliferation of SiHa and HEK293 cells.Western blotting was applied to detect E7 and pRb protein expression.Results The SiHa cells in Cri group showed DSB formation at 48 h after transfection.The apoptosis rate of Cri group at 48 h was 26.6％,higher than 2.6％ in control group (x2 =5.455,P =0.020) and 3.1％ in C9 group (x2 =6.279,P =0.012).The apoptosis rates of control,C9 and Cri group were 7.4％,7.6％,7.9％ for HEK293 cells respectively.Compared with the control and C9 group,the apoptosis rate of the Crigroup showed no statistical significance (x2 =0.032,P =0.858;x2 =0.034,P =0.853).After 72 h transfection,the inhibition rate of SiHa cells in Cri group was 29.4％,higher than 15.0％ in control group (x2 =22.481,P =0.000) and 18.0％ in C9 group (x2 =24.879,P =0.000).The inhibition rate of the HEK293 cells in Cri group was 3.2％,and it showed no significant difference compared with the inhibition rate of C9 group (2.2％,x2 =2.857,P =0.091) and control group (2.3％,x2 =3.438,P =0.064) respectively.Down-regulated expression of E7 protein and up-regulated expression of pRb protein were detected of the SiHa cells in Cri group compared with the control group,while the E7 protein and pRb protein level did not show difference in the C9 group.Conclusion CRISPR specifically targeting HPV16-E7 oncogene can promote apoptosis of SiHa cells,and inhibit the cell proliferation.It is speculated that CRISPR system may induce DSB event of E7 gene,and result into increased expression of tumor suppressor protein pRb.

To determine immune responses and immunopathology in ICOSL knockout (ICOSL KO) mice infected with Schistosoma japonicum,ICOSL- KO mice and wild-type C57BL/6J mice were used as experimental models for Schistosoma japonicum infection.The splenic lymphocytes were isolated from the mice the day before infection (0 week) as well as 4,7,12,16 and 20 weeks post infection,and stimulated with SEA for 72 hours in culture.The concentrations of Th1 cytokines (IFN-γand IL- 12) and Th2 cytokines (IL- 4,IL-10 and IL-13) in the culture supernatants were measured by sandwich ELISA.The levels of SEA-specific IgG antibody and its subtypes (IgG1 and IgG2a) were measured in mouse sera by ELISA.Pathological changes of hepatic granuloma in mice were determined by hematoxylin and eosin (H&E) staining.After the infection,the levels of Th1 cytokines,IFN- γ and IL 12,in ICOSL- KO mice were higher than those in wild-type C57BL/6J mice.However,the levels of Th2 cytokines (IL- 4,IL- 10 and IL- 13) were significantly decreased in ICOSL-KO mice compared to those in wild-type C57BL/6J mice.The levels of SEA-specific IgG antibody and its subtypes (IgG1 and IgG2a) in the sera of ICOSL- KO mice were also significantly lower than those of wild -type C57BL/6J mice.Moreover,the Th2 differentiation index was lower in ICOSL- KO mice than in wild-type C57BL/6J mice at 4,7,12,16 and 20 weeks post-infection.Similarly,the ratio of IgG1/IgG2a in ICOSL-KO mice was significantly lower than that in wild- type C57BL/6J mice at 7,12 and 16 weeks post- infection.Furthermore,throughout the course of disease progression,the volume of hepatic egg granuloma in ICOSL- KO mice was significantly smaller than that in wild-type C57BL/6J mice.In conclusions,there is a substantially down-regulated Th2 immune response in ICOSL- KO mice infected with Schistosoma japonicum,thus results in an attenuated hepatic lesion caused by egg granulomas.The findings indicate that the ICOS ICOSL co-stimulatory pathway plays an important role in the hepatic egg granuloma formation of schistosomiasis.

Bone is an active tissue in which the processes of remodeling are continuous to ensure normal bone integrity and strength. Steroids play an important role in regulating bone growth, development and remodeling. Glucocorticoids excess will induce bone damages especially osteoporosis. Otherwise, estrogen and androgen are bone protective steroids in both female and male. To develop a new selective steroid receptor modulator is one of the targets in future study to treat osteoporosis.
