OBJECTIVETo examine the oral health status among the orphan children and adolescents of Chongqing and assist in planning of the oral health programs.

METHODSAccording to the third national oral health investigation of epidemiology, the dental caries, gingival bleeding and calculus was examined among 317 orphan living in Chongqing, by cluster sampling. The statistical software SPSS 17.0 was used for the data analysis.

RESULTSIn primary and permanent teeth, the prevalence of dental caries and mean DMFT (dmft) were found to be 50.00%, 1.94 +/- 2.81 and 39.53%, 0.90 +/- 1.38. There were no significant difference between female and male (P>0.05). But there was significant difference of the prevalence of permanent tooth caries between the age group under 12 (include 12) and above 12 (P < 0.05). It was also found that 35.25% of the orphan children and adolescents had caries in the first permanent molar, and there was significant difference between female and male (P < 0.05). Neither of the caries teeth above was treated nor the healthy teeth were sealed. The prevalence rate of gingival bleeding was 78.22%, and the calculus rate was 67.66%.

CONCLUSIONThe oral status of the orphan is poor, and this community has experienced a low utilization of preventive or therapeutic oral health services. In the future work, orphans should be considered as a priority group when make plans for oral health care.

Objective To explore the effectiveness of KAP-HBM-TTM(KHT)-based health management on patients with chronic diseases in community. Method From April 2014 to June 2015, 834 patients with chronic diseases living in Desheng Community were randomly sampled and assigned to the intervention group (n=423, and the control group n=411). The K-H-T mode was used for the intervention group, and the routine management mode was applied to the control group. Using self-made questionnaire we tested two groups of patients' knowledge, attitude and life-style behavior. Chi-square test was used for data analysis. Result After one year KHT-based health management, the proportion of patients with reaching the standard knowledge such as diagnosis based, risk factors, correct treatment method, life-style for prevention of chronic disease and regular check-up of the intervention group (84.9%, 88.0%, 95.2%, 89.6%, 96.9%) obviously raised compared with the control group (56.3%, 53.6%, 59.5%,55.8%, 62.7%), and the difference was statistically significant (? 2=81.270, 118.394, 155.166, 119.672, 150.173,P<0.05). The proportion of patients with reaching the standard attitude such as on the importance of chronic diseases, the family doctor service, the nurses' health management and changing risk factors of the intervention group (80.8%, 78.2%, 81.8%, 77.5%) obviously raised comapred with the control group (59.0%, 54.3%, 52.8%, 56.5%), and the difference was statistically significant (?2=46.573, 52.429, 78.435, 40.744,P<0.05). The proportion of patients with reaching the standard life-style behavior such as diet, physical exercises, psychological states, correct medication, monitoring blood pressure and glucose of the intervention group (76.7%, 72.2%, 90.6%, 99.3%, 86.1%,42.0%) obviously raised than the control group (30.9%, 30.6%, 58.0%, 73.1%, 57.5%, 28.9%), and the difference was statistically significant (? 2=174.142, 142.147, 115.318, 119.783, 83.164, 15.341,P<0.05). The rate of blood pressure and glucose control of the intervention group (84.2%, 74.8%) also improved as compared with the control group (74.3%, 60.0%), and the difference was statistically significant (? 2=11.598, 20.576,P<0.05). Conclusion KAP-HBM-TTM (KHT)-based health management was proved to be effective in the control of chronic diseases of community and improve the effectiveness of the management.

[ ABSTRACT] AIM:To investigate the effect of HOX transcript antisense RNA ( HOTAIR) on the migration and invasion abilities of liver carcinoma HepG 2 cells.METHODS:The expression of phosphoinositide-3-kinase regulatory sub-unit 3 (PIK3R3) in the liver cancer and normal liver tissues was detected by immunohistochemistry .The efficiency of gene silencing of HOTAIR or PIK3R3 by LV3-shHOTAIR or LV3-shPIK3R3 was determined by qPCR and Western blot .The mi-gration and invasion abilities of HepG 2 cells after silencing of HOTAIR and PIK3R3 were measured by wound healing assay and Transwell Matrigel invasion assay .The expression of miR-214 after silencing of HOTAIR and PIK3R3 was analyzed by qPCR.The expression of HOTAIR and PIK3R3 in the HepG2 cells was also evaluated by qPCR after transfected with miR-214 mimics or miR-214 inhibitor .Dual-luciferase reporter assay system was used to determine the regulatory effect of miR-214 on HOTAIR and PIK3R3 expression.RESULTS:PIK3R3 expression increased significantly in the liver cancer tissues compared with normal liver tissues .The abilities of invasion and metastasis of hepatocellular carcinoma were reduced after silencing of HOTAIR and PIK3R3.miR-214 expression was increased when silencing of HOTAIR and PIK3R3 was per-formed.HOTAIR and PIK3R3 expression was reduced after transfection with miR-214 mimics.HOTAIR and PIK3R3 ex-pression was increased after transfection with miR-214 inhibitor.The results of dual-luciferase reporter assay test showed that miR-214 directly regulated HOTAIR and PIK3R3 transcription activity .CONCLUSION: HOTAIR regulates the ex-pression of PIK3R3 through miR-214, thus promoting the migration and invasion abilities in the liver cancer cells .

BACKGROUND:The Y-shaped mesh graft material weaved using lightweight polypropylen has the appropriate porosity, which not only can make the vaginal tissues grow and fuse rapidly on the mesh, but also can maintain good biological strength to ensure the fixed strength for the presacral suspension. OBJECTIVE:To retrospectively analyze the clinical effect of Y-shaped mesh for the biological function reconstruction of the female pelvic floor. METHODS:Ten female cases of pelvic floor dysfunction were enrol ed, aged 37-73 years, and al were given the treatment of sacral colposuspension under laparoscopy. Then perioperative complications were recorded;patients were fol owed up regularly to record the Pelvic Organ Prolapse Quantification (POP-Q) score at different time points;and the subjective satisfaction was investigated using the Pelvic Floor Impact Questionnaire (PFIQ-7). RESULTS AND CONCLUSION:After at least 6-month fol ow-up, no postoperative pelvic infection, nerve damage and complications appeared, the patients healed wel , and no mesh erosion, infection and other adverse reactions occurred. The POP-Q and PFIQ-7 scores at 1, 3 and 6 months after repair were significantly improved than those before repair (P<0.05). These results suggest that the Y-shaped biological mesh repairing female midpelvic floor dysfunction has good biocompatibility, and can restore the anatomy of the pelvic floor.

Objective To observe the clinical efficacy of Sanyinjiao acupoint sticking with Gushen Yutai Tie on threatened abortion. Methods A total of 216 women diagnosed with threatened abortion were randomly assigned to trial group (108 cases) and control group (108 cases). Both groups were treated with TCM syndrome differentiation treatment and progesterone soft capsule, and the trial group was treated with Gushen Yutai Tie acupoint sticking at Sanyinjiao (SP6) additionally. One treatment course was five days, and both groups were treated for three courses. Vaginal bleeding and lower abdominal pain, lumbar pain, nausea and vomiting were observed, pulsatility index (PI) and resistance index (RI) of the uterine artery were detected after treatment. Results The total effective rate in the trial group was 97.22% (105/108), which was significantly higher than that of 90.74% (98/108) in the control group (P<0.05). Symptom scores in the trial group were also significantly higher than those in the control group (P<0.01). PI and RI in the ineffective (pregnancy failure) group were much lower than that of effective (threatened abortions with normal outcome) group (P<0.01). Conclusion The treatment that Gushen Yutai Tie acupoint sticking at Sanyinjiao combined with TCM syndrome differentiation and progesterone soft capsule had a better effect to improve pregnancy success rate in threatened abortion. PI and RI in uterine artery could be used to evaluate the outcome of pregnancy.

OBJECTIVETo investigate the effects of angiotensin II (Ang II) antagonist telmisartan on retina vessel endothelial cell apoptosis and its impact on the ACE2-Ang-(1-7)-Mas axis in spontaneous hypertensive rats (SHR).

METHODSThirty-six SHR 16 week-old were randomly divided into 3 groups (n = 12 each): SHR, SHRT (telmisartan 10 mg · kg-1 · d-1 by gastric gavage) and SHRTA group (telmisartan 10 mg · kg-1 · d-1 by gastric gavage plus intravenous injection of A-779 0.5 mg · kg-1 · d-1), twelve WKY rats served as normotensive control group. Systolic blood pressure was measured at pre-treatment and 8 weeks later. After 8 weeks, rats were sacrificed, the expression of ACE2 and Mas in retina were analyzed by qRT-PCR, Western blot and Immunohistochemistry, the Ang-(1-7) concentration in serum was measured by ELISA. Specimens were obtained and stained by hematoxylin and eosin, and the morphology of retina vessel was observed. Apoptosis of vessel endothelial cells were determined by using terminal deoxynucleotidyl transferase mediated dUTP nick end labeling method.

RESULTSThe systolic blood pressure of SHR, SHRT and SHRTA groups at baseline were significantly higher than age-matched WKY group (all P < 0.01). Eight weeks later, the systolic blood pressure group was significantly lower in SHRT group than in the SHR group (P < 0.01), this effect was partly reversed in SHRTA group. The retinal ACE2 mRNA and protein expression was significantly lower in SHR group than in WKY and SHRT groups (P < 0.01), which was similar between SHRT group and SHRTA group (P > 0.05). The retinal Mas mRNA and protein expression were significantly lower in SHR group compared to WKY and SHRT groups (all P < 0.01), which was significantly lower in SHRTA group than in the SHRT group (P < 0.05). ELISA results showed that serum Ang-(1-7) protein level was significantly lower in SHR group than in WKY group and SHRT group (both P < 0.05), which was lower in SHRTA group compared to SHRT group. Retinal vessel endothelial cell apoptosis was higher in SHR group than in WKY group, which could be reduced by cotreatment with telmisartan and this beneficial effect could be reversed by A-779.

CONCLUSIONTelmisartan can reduce retinal vessel endothelial cell apoptosis via upregulating the ACE2-Ang-(1-7)-Mas axis.

The patient was a young woman with a history of syphilis, gross hematuria onset, chronic course, exacerbation in the second and third trimesters. The clinical manifestations were gross hematuria, nephrotic syndrome, rapidly progressive glomerulonephritis requiring dialysis, decreased complement C3 and C4, and monoclonal IgG-kappa deposition in blood and urine immunofixation electrophoresis. Membranous proliferative glomerulonephritis with crescent formation under renal pathological light microscopy, only single IgG3 deposition in the immunofluorescent IgG subtype, and restrictive expression of light chain kappa, were diagnosed as proliferative glomerulonephritis with monoclonal IgG (IgG3-kappa) deposits (PGNMID). The was the first case with a history of syphilis that worsened during pregnancy. After treatment with bortezomib, cyclophosphamide, and dexamethasone, the patient was finally released from dialysis, renal function recovered, and proteinuria improved.
