Visceral leishmaniasis (VL) is a parasitic disease ,which is still endemic in western China .An earthquake struck south-western China on May 12th ,2008 ,which affected Longnan City of Gansu Province considerably .The objective of this survey is to determine the effect of the Wenchuan earthquake on the Kala-azar epidemic in Longnan City .In this study ,VL cases were collected from 2005 to 2013 and diagnosed on positive test for anti-rK39IgG antibodies by the Kala-azar Detect rK39 dip-stick (InBios ,USA) .The incidence rates were calculated among various counties of Longnan City with SPSS 19 .0 soft-ware .The epidemiological characteristics of the disease were analyzed before and after the Wenchuan earthquake .From 2005 to 2013 ,there were 825 VL cases in Longnan City ,with an annual incidence of 3 .36/100 000 and a significantly higher incidence in males than that in females (P＜ 0 .001) .All age groups were affected .During this period ,there was an obvious upward trend from 2005 to 2008 ,and a distinct downward tendency since 2010 .The incidences of VL between 2008 and 2010 were sig-nificantly different with that in other years (P＜0 .01) .Results revealed that VL was widespread in Longnan City ,which was likely exacerbated by the earthquake in 2008 .Earthquake created diverse natural environment and social circumstances ,w hich may contribute to the spread of the VL epidemic .Together ,our data strongly suggest that the epidemic of VL should be close-ly monitored after earthquake .

OBJECTIVETo assess clinical therapeutic effect and safety of acupuncture combined with fuxiting on depression.

METHODSFifty-three cases of depression were divided into an observation group (n = 30) treated by acupuncture combined with fuxiting and a control group treated by fuxiting. Their clinical therapeutic effects were assessed by HAMD, HAMA and CGI, and adverse effects by TESS.

RESULTSAfter treatment of 6 weeks, the total effective rate was 80.0% in the observation group and 69.6% in the control group with no significant difference between the two groups (P > 0.05). There were significant differences in scores of HAMD and HAMA before and after treatment in the two groups (P < 0.01), with no significant difference between the two groups (P > 0.05). The adverse effect in the observation group was less and milder than that in the control group.

CONCLUSIONAcupuncture combined fuxiting has good therapeutic effect on depression with less and mild adverse effects.

Background The proliferation and migration of vascular endothelial cells is a primary link during angiogenesis.Studies showed that heat shock protein B6 (HspB6) promotes the secretion of multiple angiogenesis-related factors and therefore leads to neovascularization.Understanding the effects of neutralizing HspB6 antibody on the biological behavior of human choroidal vascular endothelial cells has an important significance in the target treatment of choroidal neovacularization diseases.Objective This study was to address the role and mechanism of neutralizing HspB6 antibody in tube formation of human choroidal vascular endothelial cells.Methods Human choroidal vascular endothelial cell line was normally cultured and harvested for total RNA extraction.Expressions of HspB6 mRNA and protein in human choroidal vascular endothelial cells were detected by reverse transcription PCR (RT-PCR) and flow cytometry (FCM).The cells were seeded on 96-well plate covered with matrigel at the density of 2×104/hole.Then the neutralizing HspB6 antibody at the concentration of 100 μg/Land 500 μg/L was added into the medium respectively,and the control cells were set without the addition of HspB6 antibody.The number of capillary tubes was calculated 12 hours after culture by three-dimensional matrigel assay.In addition,0,50,100,500 μg/L of neutralizing HspB6 antibody were added into the cell medium separately for 24hours,cell counting kit-8 (CCK-8) method was employed to assay the inhibitory rate(IR) of the cells.Transwell test was used to count the cell number across chamber membrane for the evaluation of migration ability of the cells.The apoptosis of the cells was assayed by FCM.Results Both HspB6 mRNA and protein were expressed on human choroidal vascular endothelial cells.The number of capillary tube formation of human choroidal vascular endothelial cells was (67.25±5.75),(60.39±6.41) and (39.76±10.73) /field in the 0,100 and 500 μg/L neutralizing HspB6 antibody groups,with significant difference among them (F =10.210,P =0.012),and the tube number was significantly less in the 500 μg/L neutralizing HspB6 antibody group compared with 0 μg/L neutralizing HspB6 group (P =0.005).The IR of neutralizing HspB6 antibody to the cellular proliferation and migration was enhanced with the increases of concentration and time lapse(Fconcentration =7.485,P =0.002 ; Ftime =16.684,P =0.001).The number of the cells through Transwell chamber membrane was 14.0 ± 2.5,11.1 ± 0.8,6.6 ± 0.1,6.7 ± 0.2 in the 0,50,100,500 μg/L neutralizing HspB6 antibody group respectively,and that in the 100 μg/L and 500 μg/L neutralizing HspB6 antibody group was lessened in comparison with the 0 μg/L neutralizing HspB6 antibody group(both at P=0.000).The apoptosis rate of the cells was (22.73 ± 2.53)％ in the neutralizing HspB6 antibody group,which was significantly lower than (13.33±2.08) ％ of the control group (t=4.967,P=0.008).Conclusions Neutralizing HspB6 antibody inhibits capillary tube formation of human choroidal endothelial cells in vitro in dose-and timedependent manner,probably through suppressing the proliferation and migration and promoting the apoptosis of choroidal endothelial cells.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.

Objective To analyze the differences in the expression levels of the lncRNA MALAT1, NEAT, NEAT2 in peripheral blood mononuclear cell (PBMC) from tuberculosis patients and healthy controls. Methods We detected the lncRNA expression levels in PBMC from 79 tuberculosis patients and 82 healthy controls by quantitative reverse transcription polymerase chain reaction, and analyzed the correlation between lncRNA expression levels and some clinical features and laboratory indicators in tuberculosis patients. Results The expression levels of MALAT1, NEAT1 in PBMC of tuberculosis patients were significantly higher than healthy controls (Z=-4.386, P<0.001; Z=-10.175, P<0.001). There was no significant difference in the expression of NEAT2 between tuberculosis patients and healthy controls (Z=-0.203，P=0.839). The correlation results of lncRNA levels and some clinical features, laboratory indicators in tuberculosis patients suggested that the NEAT2 level in PBMC of newly treated tuberculosis patients was higher than recurrent tuberculosis patients, while the NEAT2 level in PBMC of sputum smear positive tuberculosis patients was lower than that of sputum smear negative tuberculosis patients (all P<0.05). There was a negative correlation between MALAT1 level and erythrocyte sedimentation rate (rs=-0.256, P=0.034). Conclusion MALAT1 and NEAT1 are abnormally expressed in PBMC of tuberculosis patients, and may be involved in the pathogenesis of pulmonary tuberculosis.

OBJECTIVETo study the changes in pelvic floor morphology and relationships of the pelvic organs in patients with outlet obstructive constipation (OOC).

METHODSFifty-nine OOC patients and 12 healthy volunteers were examined by simultaneous pelvic four-contrast defecography, including pelvicography, vaginal opacification, voiding cystography and defecography. The levels of perineum, peritoneum and bladder, and anorectal angle were measured and recorded.

RESULTSAmong the 59 OOC patients, 46 cases of internal rectal prolapse (IRP), 29 cases of pelvic floor hernia, 7 cases of rectocele (RC), 7 cases of spastic pelvic floor syndrome (SPFS), 5 cases of descending perineum syndrome were diagnosed by pelvic four-contrast defecography. Six cystoceles and 10 uterine prolapses were also found by pelvic four-contrast defecography. Compared with healthy volunteers, OOC patients had significantly large anorectal angles during defecation (P<0.05), abnormality descending of perineum during rest and defecation (P<0.05, P<0.01), and a deep pouch of Douglas during defecation (P<0.01). OOC patients combined with urinary system symptoms had an abnormal descent of the bladder during rest and defecation (P<0.05, P<0.01).

CONCLUSIONPelvic four-contrast defecography is an effective method for the diagnosis of IRP, RC, pelvic floor hernia, peritoneocele, cystocele and uterine prolapse, and is helpful in the selection of proper surgical procedures for the treatment of OOC.
