Objective The control rate of blood pressure in hypertension patients is very low in our country , while follow-up intervention can significantly improve the situation .This study aimed to evaluate the clinical effects of anti-hypertension under follow-up intervention . Methods From October 2013 to October 2014 , 125 patients with hypertension were chose as the study objectives after first clinical anti-hypertension and were divided into intervention group (follow-up,n=65) and control group(no follow-up,n=60). Comparative analysis was made in blood pressure control , compliance with therapy and cardiovascular event incidence between the two groups after 12 weeks'intervention. Results After 12 weeks, diastolic and systolic blood pressure in intervention group was signifi-cantly lower than that in control group (P<0.05).Significant difference was also found in the compliance with drug-taking between in-tervention group and control group (73.8%vs 43.3%, P<0.01).During the follow-up period, 1 case in the control group suffered stroke and unstable angina pectoris hospitalized for treatment . Conclusion Follow-up intervention after clinical service can improve the efficacy of blood pressure control and encourage the patients to live healthy lifestyle .

Objective:To investigate the efficiency of carbon nanotube(CNT)-PAMAM mediated entrance of anti-survivin oligonucleotide into HepG2 cells,and its effects on the proliferation of HepG2 cells.Methods:CNT-PAMAM-anti-survivin oligonucleotide compounds were prepared and characterized by AFM and 1% agarose gel electrophoresis analysis.TEM was used to observe the distribution of CNT-PAMAM-ASODN compounds in HepG2 cells.CNT-PAMAM-ASODN compounds were added into the medium and co-cultured with HepG2 cells for 24 h,48 h,72 h,and 96 h at 37℃,5% CO_2.MTT method was used to detect the effects of ASODN and CNT-PAMAM-ASODN on the proliferation of HepG2 cells.Results:CNT-PAMAM-ASODN compounds were successfully synthesized via AFM and agarose gel electrophoresis.TEM showed that the compounds were located in the cytoplasm.When CNT-PAMAM-ASODN(1.0 ?mol/L)and ASODN(1.0 ?mol/L)were used for a 48 h culture,the inhibitory rates of HepG2 cells were(45.97?4.28)% for CNT-PAMAM-ASODN compounds group,(9.33?0.85)% for ASODN group,and(6.37?0.69)% for CNT-PAMAM group.CNT-PAMAM-ASODN compounds at 1.5 ?mol/L inhibited HepG2 cells by(70.22?7.25)%,and the inhibitory effects were in a time-and concentration-dependent manner.There was statistical difference between experiment group and control group(P

OBJECTIVE The aim of the study was to evaluated the difference and consistency in tumor size measured by sonographic and pathological examination in papillary thyroid carcinoma(PTC).METHODS A total of 114 patients with PTC, including 122 malignant nodules, was collected from Hangzhou First People's Hospital between Jun 2012 and Jun 2014. The tumor sizes were measured by preoperative sonographic and postoperative pathologic evaluation. Pearson correlation analysis, paired t-test, and Bland-Altman plot were used to evaluate the correlation and consistency in tumor size measured by the two methods.RESULTS Pearson correlation analysis showed that the largest tumor size measured by sonography were positively correlated with pathologic size (r=0.957, P=0.000). Paired t-test showed that there were statistically difference between sonographic size and pathological size (8.24±5.06) mmvs (7.79±4.75) mm,P=0.001. The absolute difference value of the largest tumor size measured by the two methods was from zero to 6.5 mm, with the average of (1.03±1.14) mm. Bland-Altman analysis showed that the limits of agreement (LoA) of difference was from -2.41 mm to 3.33 mm, with the 95% confidence interval from -2.87 mm to 3.78 mm.Within the limit of the consistency, the maximum moduli was 2.9 mm.CONCLUSION There is a significant discrepancy between the preoperative sonographic and the pathologic size of the papillary thyroid carcinoma, which should be taken into account in clinical practice.

To understand Lophatherum gracile plant community's structural characteristics, a survey of community structure and species diversity was conducted through quadrat sampling in Yongchuan district of Chongqing. The results showed that there were 386 species vascular plants, belonging to 117 families and 229 genera. Based on habitat, community structure and species composition, L. gracile were found in three community types: Pinus massoniana community, banboo community, shurb community. Vertical structure was composed of three layers, including tree layer, shrub layer and herb layer. Species in shrub layer was the richness. P. massoniana is the only dominant species of the community, it can not regenerate naturally, the shrub layer has a greater effect on the community of L. gracile in the future. In addition, the banboo community and shurb community is not stable because of human's activity. Therefore, the community characters of L. gracile should be taken care of conservation when the resources are utilized.

OBJECTIVETo investigate the influence of total flavonoids of epimedium (TFE) on the streptozocin (STZ)-induced kidney injury in diabetic rats and discuss the possible mechanism.

METHODSDiabetes was produced by a single injection of streptozocin (40 mg/kg, iv) in male SD rats. The rats were randomly divided into three groups (n = 10): control group, model group and TFE group (100 mg/kg, ig). Animals were sacrificed 12 weeks later. The level of blood glucose, blood urea nitrogen (BUN) and creatinine (Cr) as well as the renal index were determined. Detect the specific biochemical of renal tissue: superoxide dismutase (SOD), malondialdehyde (MDA). Use masson staining to observe the morphology of the renal tissue. Immunohistochemistry was employed to determine the protein levels of transforming growth factor-beta1 (TGF-beta1).

RESULTSCompared to control group, the enhancement of blood glucose, renal index, BUN and Cr was found in model group, which was significantly attenuated by treatment with TFE. Meanwhile, elevated MDA level in renal tissue as well as decreased SOD activities in renal tissue were significantly remitted by TFE. Furthermore, TFE decreased the expression of TGF-beta1.

CONCLUSIONTFE can evidently relieve renal damage in rats with diabetic nephropathy induced by STZ, which might be related to antioxidation and modulating the expression of TGF-beta1 protein.

OBJECTIVETo explore the relationship between the expression of caspase-3 in testicular germ cells of rats with experimental left varicocele (ELV) and apoptosis of germ cells.

METHODSTwenty-four male SD rats were randomly divided into three groups with eight animals each: sham-operation group (SOG), 30-day post-operation group (PG1) and 60-day psot-operation group (PG2). ELV model was established by the partial ligation of the left renal vein. To detect apoptosis of germ cells and expression of caspase-3, TUNEL assay and immunohistochemistry (SABC) were used respectively.

RESULTSThe number of caspase-3 positive germ cells per tubular cross section in left and right testes of rats in SOG, PG1, PG2 were 0.1175 +/- 0.0129, 0.2463 +/- 0.0421, 0.2938 +/- 0.0511 and 0.1650 +/- 0.0192, 0.2538 +/- 0.0219, 0.2775 +/- 0.0343, respectively. Compared with SOG, the expression of caspase-3 in bilateral testes of rats in PG1 and PG2 were increased, and the differences were statistically significant(P = 0.0115 and P = 0.0144).

CONCLUSIONExpression of caspase-3 protein increased in germ cells of rats with ELV, which may be one of the molecular mechanisms related to excessive testicular germ cell apoptosis.

OBJECTIVETo evaluate the clinical practice of laparoscopic rectopexy in the treatment of severe rectal prolapse.

METHODSFrom March 1998 to February 2007, 4 cases of complete rectal prolapse, including 1 male and 3 female,ranged 21-82 years old, were treated by laparoscopic rectopexy. In one case, the posterior wall of rectum was freed and elevated, and pre-rectal introcession was closed by silk suture, then the posterior wall was suspended and fixed on sacral promontory fascia, finally the sigmoid colon was fixed by sutures on the fascia of left psoas major. In other three cases, insertion of mesh was performed. Rectum was freed and elevated to the level of levalor ani. A sheet of T-shape polypropylene mesh was placed posterior to the rectum, whose lower margin was at the level of levator ani and wrapped around the rectum covering except the anterior wall. The free margin of the mesh was sutured on the muscular layer of rectum, then the mesh was put posterior to the rectum and fixed on the sacral promontory fascia by clipping to repair hernia. After that, the pelvic peritoneum was closed, and finally the sigmoid colon was fixed by sutures on the fascia of left psoas major.

RESULTSFour operation procedures were completed successfully. There was no conversion operation. The time was consumed 92.5 (80-100) min, and the bleeding amount was 6.5 (5-10) ml. No post-operative complications were found. Urine incontinence and encopresis were relieved. No recurrence and constipation was found after 2 months to 3 years follow up postoperatively.

CONCLUSIONLaparoscopic rectopexy is a safe, workable and effective procedure, which can reduce operative trauma and shorten hospitalization time.
