Objective To investigate the clinical effect and the safety of paroxetine in the treatment of elderly patients with chronic primary insomnia. Methods Ninety elderly patients who met Chinese Classification and Diagnostic Criteria of Mental Disorders, 2nd Rev Ed, (CCMD 2 R) for elderly patients with chronic primary insomnia were randomly divided into paroxetine group (30 cases), alprazolam group (30 cases), and placebo group (30 cases) for 12 weeks as a course. Effects were evaluated with Pittsburgh Sleep Quality Index (PSQI) and treatment emergence symptoms scale (TESS) before and after the 4th, 8th, 12th week of treatment. Results The excellent response rate of paroxetine group and alprazolam group were 83% and 53% respectively( P

Objective To observe the therapeutic efficacy of continuous arterial infusion chemotherapy combined with radiofrequency hyperthermia in the treatment of patients with advanced colorectal cancer.Methods A total of 20 advanced colorectal cancer patients with various distant metastasis were treated by the combined continuous intra-arterial infusion chemotherapy and radiofrequency hyperthermia.For the chemotherapy,a dose of 200mg/m2 surface body area of calcium folinate(CF) was given for 1 to 3 days.80mg/m2 of cisplation was infused intravenously for the first day and repalced by etoposide Vp16,60mg/m2 for 1 to 3 days in patients with renal dysfunction.For intra-arterial infusion,a dose of 500mg/m2 5-FU was given for 72 hours.For patients with liver metastases,chemoembolization(ADM 30mg/m2+MMC 6mg/m2 mixed with ultra-lique fied lipiodol) was carried out.Radiof requency hyperthermia with a frequency of 41MHz was performed on the second day after chemotherapy.Results Response rates were as sessed by CT scan and ultrasonography.The overall response rate(CR+PR) of the cases was 70.0%.No serious side effect or complication was found in the course of chemotherapy.Local pain and lipid nodule were occasionally observed in some patients after hyperthermia.Conclusion Continuous intra-arterial infusion chemotherapy in combination with radiofrequency hyperthermia is an useful and safe method for the treatment of patients with advanced colorectal cancer.

Objective:To investigate the effect of HMGB1 and TLR-4 in the renal injury of SLE.Methods:The level of HMGB1 in serum from 16 patients suffering from SLE without kidney damage,18 patient with lupus nephritis (LN),and 12 healthy individuals were measured by ELISA.The fresh PBMCs were isolated and the total RNA was extracted.Then the mRNA expression of HMGB1 was amplified by RT-PCR.Flow cytometric analysis(FCM) was performed to study cell surface markers and the expression of TLR-4.Results:RT-PCR and ELISA results showed that the expressions of mRNA and protein were higher in patients with LN than in SLE without kindey damage and healthy people.The expression of TLR-4 in CD14+ monocytes of patients with LN was higher either,while there were no significant changes in CD3+ T cells among LN,SLE and healthy control.Conclusion:PBMCs in patients with LN could synthesize and secrete HMGB1 initiatively,which are correlated with serum HMGB1 level.HMGB1 might play a role in autoimmunity of lupus nephritis partly by activation of monocytes through its binding to TLR-4.

Objective To evaluate the strategies and effect of surgical treatment for concomitant abdominal aortic aneurysm (AAA) and colorectal cancer (CRC). Methods Literatures on concomitant AAA and CRC published from January 1988 to December 2008 were retrieved from Pubmed, Sciencedirect, Ovid, CBMdisc, CNKI and et al, and correlated indexes were extracted for analysis. Differences among the groups were analyzed using the t test, chi-square test and fisher's exact test. Results A total of 367 cases of concomitant AAA and CRC treated by operation were retrieved. The length of operation delay of patients who received radical resection of CRC first was (115 ± 21 )days, which was significantly longer than (42 ± 8 )days of patients who received open abdominal aortic aneurysm repair (OAAR) first (t = 18. 9, P <0.05). The 30-day complication rate and accumulative length of hospital stay of patients who received one-stage radical resection of CRC + OAAR were 10.5% ( 12/114 )and (23 ±6) days, and 26.0% (47/181) and ( 16 ±4)days of patients who received two-stage radical resection of CRC + OAAR, with a significant difference ( χ2 = 10.42, t = 12. 01, P <0.05 ). The accumulative length of hospital stay of patients who received radical resection of CRC + endovascular aneurysm repair (EVAR) was (12 ±4) days, which was significantly shorter than that of patients who received radical resection of CRC + OAAR [ ( 19 ±5 ) days ] ( t = 9.48, P < 0. 05 ). The 4-year survival rate of patients who received two-stage radical resection of CRC + OAAR was 43.5% (27/62), which was significantly lower than that of patients who received two-stage radical resection of CRC + EVAR [69.2% (18/26) ] or one-stage radical resection of CRC + OAAR [73.7%(14/19) ] (χ2 =4.83, 5.28, P<0.05). Conclusions If the diameter of AAA is under 5 cm, radical resection of CRC should be firstly carried out; but if the diameter of AAA is above 5 cm, OAAR should be firstly carried out to prevent the rapture of tumors. One-stage surgery is better than two-stage surgery if patients could tolerate it.

Objective To investigate the correlation between NF-?B/COX-2 signal pathway and cell proliferation in diabetic nephropathy. Methods Uninephrectomized STZ-induced male Wister rats were used as animal model. Using immunohistochemistry to detect NF-?B and COX-2 protein expressions in diabetic kidneys at the 16th week. HKC were cultured separately in normal or high glucose medium for 24,48,72 h.The expression of NF-?B and COX-2 protein was detected by flow cytometry and the expression of PCNA was detected by immunocytochemical staining. Results 1 Volum of glomeruli, mesangial matrix, thickness of glomerular and tubular basement membrane increased in diabete group; 2 COX-2 were expressed in cytoplasm of tubules and glomeruli by immunohistochemistry. Compared with control group, the expression of COX-2 was higher; activated NF-?B expressed in nucli of both tubules and glomeruli, There was light stainings for in control group, while enhanced stainings were observed in DM, there was a positive correlation between NF-?B and COX-2.3 Compared with those in HKC cultured in the medium with normal level glucose, the stainings were strengthened for PCNA in HKC exposed to high glucose from 24 h. 4 By FCM, the expression of NF-?B and COX-2 in HKC cultured in high glucose medium was higherthan that in normal glucose medium; the expression of NF-?B and PCNA was positively correlated with the expression of COX-2. Conclusion Activating NF-?B and elevating the expression of COX-2 play an important role in regulating cell proliferation, which may be one of the injury mechanisms of the renal cells during diabetic nephropathy.

Objective To investigate the incidence of prozone phenomenon of rapid plasma reagin (RPR) test in syphilis serolog-ic testing and its correlation with the intensity of chemiluminescent microparticle immunoassay (CMIA) results.Methods A total of 101493 patients in our hospital from January 2014 to December 2015 were performed syphilis serologic testing by CMIA ,RPR and treponema pallidum particle agglutination (TPPA).The incidence rate of prozone phenomenon in RPR testing was evaluated.Its in-fluencing factors were investigated by using the Logistic regression.Results Among 101493 serum samples ,2180 cases were posi-tive by CMIA and 767 cases were positive by RPR ,the incidence rate of prozone phenomenon was 3.3% (26/767)in RPR.The Lo-gistic regression results indicated that the incidence of prozone phenomenon was significantly correlated with CMIA S /CO values and RPR titer ,but had no correlation with sex ,age and seasonality.Conclusion Although the incidence of prozone phenomenon is low in syphilis serologic testing ,but it is enough important.The patients with higher S/CO value in CMIA test have a higher inci-dence rate of RPR prozone phenomenon.
