Objective To observe the circadian rhythm of blood pressure and investigate the impact of Norvasc and Tanatril administrated at different time points based on the theory of time therapeutics in hypertensive patients. Methods The 24-hour ambulatory blood pressure was monitored in 130 inpatients and outpatients with grade 3 or 2 hypertension from May 2008 to November 2009. A total of 34 dipper hypertensive patients were grouped into dipper blood pressure group and 5 mg/d of Norvasc and Tanatril were taken by them at 6:00 AM. A total of 96 nondipper hypertensive patients were further divided into three subgroups after adjustment for age and gender: 5 mg/d of Norvasc and Tanatril were taken by group I (n = 30) at 6:00 AM; 5 mg/d of Tanatril at 6:00 AM and 5 mg/d of Norvasc at 18:00 PM by group Ⅱ (n = 32); 5 mg/d of Norvasc at 6:00 AM and 5 mg/d of Tanatrilat 18:00 PM by group Ⅲ(n=34).The 24-hour ambulatory blood pressure monitoring was performed again after four weeks treatment and 24-hour mean systolic blood pressure(24 hSBP),24-hour mean diastolic blood pressure(24 hDBP),daytime and nighttime mean systolic blood pressure(dSBP,nSBP)and daytime and nighttime mean diastolic blood pressure(dDBP,nDBP),were analyzed.Results The 24 hSBP,24 hDBP and dSBP,and dDBP were reduced from(154.3±5.6),(95.4±3.1),(158.7±6.5),(99.6±3.7)mmHg to(137.2±3.9),(82.5±2.7),(139.7±3.8),(85.2±3.5)mmHg,respectively,in dipper blood pressure group(t=2.124,2.356,2.278,2.449,all P<0.05).The 24 hSBP and 24 hDBP of the three groups in nondipper blood pressure were decreased from(154.4±6.1),(156.7±6.7),(156.6±5.2),(95.8±2.8),(94.9±3.8),(95.7±3.2)mmHg to (139.6±4.1),(134.5±4.6),(133.4±3.5),(83.5±4.2),(80.8±5.6),(81.6±4.7)mmHg,respectively(t=2.038,2.040,2.135,2.142,2.213,2.216,all P<0.05).dSBP and dDBP were decreased from(158.6±3.50),(158.4±5.6),(159.5±4.),(98.4±3.7),(99.6±3.7),(83.9±5.2)mmHg to(138.9±5.4),(136.7±4.1),(137.4±6.4),(85.8±5.3),(83.6±5.1),(83.9±5.2)mmHg,respectively(t=2.021,2.252,2.261,2.217,2.167,2.076,all P<0.05).nSBP and nDBP were decreased from(146.7±6.9),(149.8±3.9),(150.2±4.1),(93.7±4.2),(95.7±4.3),(93.4±3.3)mmHg to(133.7±4.6),(129.8±5.7),(127.6±2.8),(87.8±2.9),(78.5±6.4),(77.8±4.8)mmHg,respectively(t=1.798,2.032,2.014,1.864,2.157,2.166,all P<0.05).There were significant differences in nSBP and nDBP among all groups after treatment(F=2.32,2.17,all P<0.05),and the effect of the drugs was better in groug Ⅱ and Ⅲ than in group Ⅰ(q=3.17,4.03,3.32,4.19,all P<0.05),but there were no significant differences between group Ⅱ and Ⅲ(P>0.05).Conclusions Blood pressure can be controlled effectively by taking two antihypertensive medictions in the morning in hypertensive dipper patient but the blood pressure of nondipper hypertensive patients were able to be controlled more efficiently by taking the two antihypertensive medictions separately in the morning and at the evening compared with that taking the two drugs together in the morning.

OBJECTIVETo explore the efficacy and safety of recombinant human thrombopoietin (rhTPO) combined with high-dose dexamethasone (DXM) in the treatment of children with refractory immune thrombocytopenic purpura (ITP).

METHODSFifty-eight ITP children who had failed first-line therapy were randomly divided into two groups: DXM treatment (n=27) and rhTPO + DXM treatment (n=31). The DXM treatment group received two continuous cycles of DXM treatment; in each cycle, patients received high-dose DXM (0.6 mg/kg daily) by intravenous drip for 4 days every 28 days. The rhTPO group received subcutaneous injection of rhTPO (300 U/kg daily) for 14 days additional to DXM treatment. The overall response rate (marked response rate + slight response rate) and adverse reactions were evaluated after 3, 7, and 14 days and 1, 2, and 3 months of treatment.

RESULTSAfter 7 and 14 days and 1 month of treatment, the rhTPO + DXM treatment group had a significantly higher marked response rate and a significantly higher overall response rate than the DXM treatment group (P<0.05). After 2 months of treatment, the rhTPO + DXM treatment group had a significantly higher overall response rate than the DXM group (P<0.05). One patient in the DXM treatment group had liver damage during the first week of treatment. There was no hypertension, fever, rash, allergy, or weakness in the two groups.

CONCLUSIONSrhTPO combined with high-dose DXM is an effective and safe approach for treating refractory ITP.

OBJECTIVETo study the expression of MUM-1/IRF4 and its significance in follicular lymphoma.

METHODSNinety-eight cases of follicular lymphoma were enrolled into the study. They were graded according to the 2008 WHO criteria. The expression of MUM-1/IRF4 protein and other markers (CD10, bcl-6, bcl-2 and Ki-67) was studied using tissue microarray and immunohistochemistry.

RESULTSAmongst the 98 cases studied, there were 24 grade 1 cases, 30 grade 2 cases, 26 grade 3A cases and 18 were grade 3B cases. The rates of expression of MUM-1/IRF4, CD10, bcl-6, bcl-2 and Ki-67 (≥ 25%) were 39.8% (39/98), 62.2% (61/98), 80.6% (79/98), 87.8% (86/98) and 50.0% (49/98), respectively. MUM-1/IRF4 predominantly expressed in high-grade follicular lymphoma and showed a significantly positive correlation with lymphoma grade (r = 0.628, P = 0.000) and Ki-67 index (r = 0.473, P = 0.000). MUM-1/IRF4 expression had a significantly negative correlation with CD10 expression (r = -0.597, P = 0.000), but no correlation with bcl-6 and bcl-2 expression.

CONCLUSIONSMUM-1/IRF4 expression is significantly higher in high-grade follicular lymphoma, indicating that these cases have a high proliferative activity, more aggressive behavior and poorer prognosis. MUM-1/IRF4, when strongly expressed, is another helpful marker for the diagnosis of high-grade follicular lymphoma.

Paired box transcription factors (paired box, PAX) and their homologues found in a large number of vertebrates and invertebrates play a key role in many stages of embryonic development. The gene family gets its name because of its conserved paired domain, in addition to its octapeptide and homologous domain. According to the composition of the domain and sequence homology, the gene family is mainly divided into four subfamilies: PAX1 / 9 (PAX1, PAX9), PAX2 / 5 / 8 (PAX2, PAX5, PAX8), PAX3 / 7 (PAX3, PAX7), PAX4 / 6 (PAX4, PAX6). Each subfamily has different characteristic structures, such as PD-OP of PAX1 / 9 subfamily, PD-OP-PTHD of PAX2 / 5 / 8 subfamily, PD-OP-PTHD of PAX3 / 7 subfamily and PD and PTHD of PAX4 / 6 subfamily. Among them, the three members of the PAX family, PAX2 PAX4 and PAX6, play an important role in multiple stages of pancreatic development and differentiation, and also play a key role in regulating the synthesis and secretion of islet hormone. Understanding the original and differentiated roles of these transcription factors in pancreas will help finding potential treatment for diabetes. Furthermore, PAX1 / 9 families may serve as potential biomarkers for evaluation of tumor development and progression, such as the methylation levels of PAX1 and expression of PAX9 in tumor. PAX3 / 7 was transcription factors involved in the development of skeletal muscle. This paper reviewed the special and temporal expression of PAX genes in a wide variety of tumor and the function and structural abnormalities PAX gene were summarized in this paper.

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.0 g) were matched according to body weight and randomly assigned to one of three groups: control, total body irradiation exposure (IR, 7.2 Gy) only, and IR (7.2 Gy) + SB203580 (15 mg x kg(-1)). 30 days survival rate was observed in the experiment. In intestinal injury experiment, the expression levels of caspase-3, Ki67, p53 and p-p38 were assayed in the mice intestine crypts. The results showed that the 30 days survival rate was 100% (control), 0 (IR) and 40% (IR+ SB203580), separately. Compared to the IR groups, the positive cells of caspase-3, p53 and p-p38 in crypt cells decreased 33.00%, 21.78% and 34.63%, respectively. The rate of positive cells of Ki67 increased 37.96%. Significant difference was found between all of them (P < 0.01). SB203580 potently protected against radiation-induced lethal and intestinal injury in mice, and it may be a potential radio protector.

OBJECTIVETo evaluate the clinical effects of total hip arthroplasty (THA) for Crowe type IV developmental dysplasia of the hip (DDH) and analyze perioperative complications.

METHODSFrom March 2000 to March 2010, 19 patients (23 hips, of them, 4 patients with bilateral hips) with Crowe type IV DDH underwent THA. There were 5 males and 14 females, with average age of 61.3 years (ranged, 41 to 72 years). All hips were treated with small acetabular components combined with medial protrusion technique in acetabular reconstruction, as well as subtrochanteric shortening osteotomy in femur. Joint function of hips were evaluated according to Harris scoring.

RESULTSAll patients were followed up with an average of 4.2 years (ranged, 1 to 8 years). Postoperative X-ray films showed all acetabular prosthesis were in true acetabulum. No loosening and nonunion were found in all patients. Harris scoring improved from preoperative 34.0 +/- 6.9 to postoperative 85.0 +/- 7.5. Complications occurred in 11 cases in the patients, including femoral split fracture in 3 cases, nerve injury in 3 cases, delayed union in 2 cases, dislocation in 3 cases.

CONCLUSIONTotal hip arthroplasty using small acetabular component, medial protrusion, femoral subtrochanteric shortening osteotomy technique for the Crowe type IV DDH can effectively restore hip function and leg length. But incidence of complications is high. The long-term follow-up is necessary for further study.

OBJECTIVETo evaluate the sensitivity and usefulness of 99mTc-sestamibi scintigraphy (SS) and neck ultrasonography (US) as preoperative localization procedures in patients with primary hyperparathyroidism (pHPT).

METHODS160 patients with proved pHPT in Peking Union Medical College Hospital from June 1983 to June 2002 were studied. There were 107 women(66.9%) and 53 men (33.1%), with a mean age of 38.9 years (10-73 years). 100 patients were underwent SS and 148 patients were underwent US prior to surgery, and the results were compared with operative and histological findings.

RESULTSThe sensitivity of SS and US in localization of the enlarged parathyroid glands was 94.0% and 85.1% respectively, and the positive predictive value of SS and US was 100% and 89.1% respectively, the overall sensitivity was 98.9% by combination of SS and US. In solitary parathyroid adenomas group (n = 145), the sensitivity of SS and US was 93.3% and 84.7% respectively; There was no significant difference (P = 0.428) in sensitivity of SS between the parathyroid glands correctly identified and undetected in classical neck location as compared with ectopic parathyroid glands, whereas significantly (P = 0.026) influenced by the US sensitivity.

CONCLUSIONSDifferent sensitivity exit between SS and VS in preoperative localization in patients with pHPT undergoing parathyroidectomy. The combined use of SS and US could increase the sensitivity of localization technique. Ectopic parathyroid had no influence on the sensitivity of 99mTc-MIBI scanning, but decreased the sensitivity of ultrasonography. The size of parathyroid tumors had effects on the sensitivity of ultrasonography. Otherwise, various conditions causing SS false negative were observed. Some interfere factors should be excluded when SS negative results were encountered in clinical practice.

OBJECTIVETo evaluate whether neutrophil-lymphocyte ratio(NLR) predicts risk of recurrence in patients with advanced colon cancer undergoing curative resection followed by adjuvant chemotherapy.

METHODSA total of 149 patients with advanced colon cancer undergoing curative resection followed by adjuvant chemotherapy(FOLFOX6 protocol) were included. NLR was calculated preoperatively and before chemotherapy. The changes in NLR and the predictive value of NLR for prognosis were analyzed.

RESULTSThe NLR of 149 patients was 2.8±1.5. NLR of 3.5 was identified according to the ROC curve. NLR<3.5 and NLR≥3.5 were classified as low and high NLR group, respectively. The 5-year recurrence-free survival(RFS) of patients with high preoperative NLR(n=22) was significantly worse than that of those with low preoperative NLR(n=127)(50.9% vs. 76.4%, P=0.025). The difference of 5-year RFS between high pre-chemotherapy NLR group(n=34) and low pre-chemotherapy NLR group(n=115) was statistically significant(50.1% vs. 71.4%, P=0.032). The 5-year RFS was 79.5% in patients with low preoperative NLR converting to high pre-chemotherapy NLR(n=16), similar to the group with high pre-chemotherapy group(P=0.077). The 5-year RFS was 17.7% in patients with high preoperative NLR reverting to low pre-chemotherapy NLR(n=12), similar to the group with low pre-chemotherapy group(P=0.978). There was significant difference in 5-year RFS between the postoperatively elevated group and postoperatively decreased group(P=0.036).

CONCLUSIONAn elevated blood NLR may be a biomarker of poor RFS in patients with advanced colon cancer after curative resection and chemotherapy.
